JP 2001-267762 A

  By the way, since the casing of the electronic device as described above has a flat and thin shape and has a space for storing the electronic component therein, even if the two casing members are connected sufficiently firmly, for example, the user can When lifting or opening the display housing, an external force such as twisting or twisting may be applied to the main body housing.

  When such an external force is applied, the four peripheral portions of the casing of Patent Document 1 are all screwed, so that a position shift occurs at the screwing portions connecting the upper and lower casing members. Then, even after the external force is released, the frictional force at the time of displacement remains, and the case member is solidified as it is, and the case may be distorted. When such a distortion occurs, locking occurs when the housing is placed on a placement surface such as a desk, and the product quality is significantly deteriorated.

The present invention has been made in consideration of the above problems of the prior art, and an object thereof is to provide with obtain a sufficient coupling strength, the electronic device including a housing capable of suppressing the quality degradation.

An electronic apparatus according to the present invention is an electronic apparatus provided with a flat box-shaped casing in which an electronic component is housed in a first casing member and a second casing member that are overlapped and connected. The one edge portion of the first casing member is provided with a protruding piece that protrudes in a direction intersecting the direction along the one edge portion, while the one edge portion of the second casing member is provided on one edge portion of the second casing member. An engagement groove with which the protruding piece is engaged is provided, and one of the first casing member and the second casing member has one edge side of the other casing member on the other casing member side. A locking member protruding toward the first housing member is provided on the one edge of the other housing member, and the first housing member and the first housing member The housing member of 2 is connected in the direction in which the locking member is locked to the locking portion so as to overlap each other, and the protruding piece is inserted into the engaging groove. Mutual relative displacement in the direction along the one edge by engagement is restricted, thereby the electronic device characterized that you have to form the housing.

  According to such a configuration, since the protruding piece provided on the first housing member is engaged with the engagement groove provided on the second housing member, the first housing member and the second housing member are engaged with each other. The relative displacement in the longitudinal direction at one edge of the casing member is restricted. As a result, for example, the user performs an operation such as gripping and lifting one edge side of the casing composed of the casing structure from a state where it is placed on a desk or the like, and twisting or twisting the casing. Even when an external force is applied, the first casing member and the second casing member are not misaligned, so that the initial state is restored again after the external force is released. For this reason, the casing constituted by the casing structure is distorted, and does not become unstable due to locking when placed on a placement surface such as a desk, thereby suppressing deterioration in product quality. be able to. In addition, since the locking member and the locking mechanism by the locking portion are provided on one edge portion where the engaging mechanism by the protruding piece and the engaging groove is provided, the first casing member and the second casing are provided. When the body member is firmly connected with high connection strength in the direction of overlapping with each other and the external force as described above is applied, the first housing member and the second housing member are separated in the connection direction. There is no end to it.

  The engagement groove may be formed of a softer material than the protruding piece. Moreover, the convex part formed with the softer material than the said protrusion piece may be formed in the inner surface of the said engagement groove | channel. Then, when the protruding piece is engaged with the engaging groove, the inner surface of the engaging groove or the convex portion provided on the inner surface can be compressed and deformed by the protruding piece, and the tolerance for fitting the two is made as much as possible. Can be set small. As a result, it is possible to more reliably prevent the relative displacement in the direction along the one edge portion between the first housing member and the second housing member, and to reliably generate rattling. Can be prevented.

  The locking member may be a hook that protrudes toward the other housing member, and the locking portion may be a recess that locks the hook portion of the hook. If it does so, it can connect reliably between two housing members, although it is a simple and easy structure.

  A direction in which the protruding piece is engaged with the engagement groove and a direction in which the hook is locked in the recess may be configured in the same direction. Then, when connecting the first housing member and the second housing member, for example, by aligning the edges of each other and overlapping the two shells so as to close the shell, The combined operation and the engaging operation of the hook claw portion with respect to the concave portion can be performed simultaneously, so that the assembling work is easy and the working efficiency is improved.

  The locking member is a screw in which a screw portion is screwed to the one housing member so that a head protrudes toward the other housing member, and the locking portion is a screw of the screw. You may be comprised by the hole which latches a head while inserting a screw part.

  The first housing member and the second housing member have at least one wall portion standing in a direction overlapping each other, and the protruding piece is the wall portion of the first housing member. The engaging groove is provided on a positioning member mounted on the inner side of the wall portion of the second casing member, and the locking member is provided on the first casing member or the The engaging portion is provided on the inner surface of the wall portion of the second housing member or the first housing member, while the locking portion is provided on the inner surface of the wall portion of the second housing member. May be. Then, the protruding piece and the engaging groove can be concealed inside the casing to improve the appearance quality of the product, and positioning in the direction orthogonal to one edge of each casing becomes accurate and easy.

  The wall portion of the first housing member is disposed between the wall portion of the second housing member and the positioning member, and the positioning member includes a wall of the first housing member. The structure provided with the contact convex part contact | abutted to the inner surface of a part may be sufficient. If it does so, positioning in the direction orthogonal to one edge part of mutual housing | casings can be performed more correctly and easily by making a contact convex part contact | abut with respect to a 1st housing member.

  In this case, the other casing may be connected to the other edge of the casing opposite to the one edge through a hinge so as to be opened and closed. Then, when the two housings are opened / closed via the hinge, the displacement on the one edge side to which the largest external force such as torsion or twisting is applied is engaged between the protruding piece and the engaging groove. Can be surely prevented.

  According to the present invention, it is possible to suppress the product quality from being deteriorated due to distortion in the housing due to the positioning action by the protruding piece and the engaging groove. In addition, the two casing members can be connected with high connection strength by the connecting action of the locking member and the locking portion.

FIG. 11 is a plan sectional view schematically showing the engaged state of the engaging mechanism 24 and the locked state of the locking mechanism 26. The cross-sectional shape along the line XI-XI in FIGS. This is shown schematically.

  First, as shown in FIGS. 2 and 3, the engagement mechanism 24 includes a protruding piece 30 formed on the inner surface side of the front wall portion 21 a of the lower cover 21 and an inner side (rear side) of the front wall portion 22 a of the upper cover 22. And an engaging groove 32 into which the protruding piece 30 is inserted.

  As shown in FIGS. 3, 5 and 6, the protruding piece 30 is formed integrally with the front wall portion 21a of the lower cover 21, and intersects the longitudinal direction of the front wall portion 21a. In this embodiment, the front wall It is a plate-like rib protruding upward and rearward from the front wall portion 21a so as to be orthogonal to the longitudinal direction of the portion 21a. Since the protruding piece 30 is integrally formed with the lower cover 21, the protruding piece 30 is made of the same metal or resin as the lower cover 21. The protruding piece 30 may have a separate structure from the lower cover 21. In this case, the protruding piece 30 may be made of a material different from that of the lower cover 21.

  As shown in FIGS. 3, 7, and 8, the engagement groove 32 is attached to the lower surface of the upper wall portion 22 d of the upper cover 22 at a position on the inner surface side (rear side) of the front wall portion 22 a of the upper cover 22. The positioning member 34 is provided. In the approximate center of the positioning member 34, a pair of left and right wall plate portions 35 that form the engaging grooves 32 are provided. The positioning member 34 is screwed and fixed to the lower surface of the upper wall portion 22d of the upper cover 22 by fixing screws 36 inserted through plate-like portions 34a extending in the left-right direction from the respective wall plate portions 35. In the case of the present embodiment, a concave portion 34b extending further in the left-right direction is formed outside the one plate-like portion 34a. The concave portion 34b is a portion where the hook 40 constituting the locking mechanism 26 is disposed.

  Each wall plate portion 35 protrudes downward from the end portion of each plate-like portion 34a, and the portions bulging upward are connected to each other, so that they are engaged in a substantially U-shape when viewed from the front. A groove 32 is formed (see also FIGS. 9 and 10). Accordingly, the gap between the inner surfaces of the wall plate portions 35, 35 facing each other is set equal to or slightly wider than the width (plate thickness) of the protruding piece 30.

  On the inner surface of each wall plate portion 35, convex portions 35a facing each other are formed extending along the vertical direction. Each convex portion 35a is in sliding contact with the protruding piece 30 inserted in the engaging groove 32 (between the wall plate portions 35 and 35) and, in some cases, is compressed and deformed to thereby form the engagement groove 32 and the protruding piece 30 with each other. It is a part for engaging the space more firmly and without rattling. Therefore, each convex portion 35a is preferably formed of a resin material that is softer than at least the protruding piece 30, such as polyacetal (POM), polytetrafluoroethylene (PTFE), or polyamide. The gap between the convex portions 35a, 35a is set to be the same as or slightly narrower than the width (plate thickness) of the protruding piece 30. In the present embodiment, the entire positioning member 34 including the wall plate portion 35 and the convex portion 35a is integrally formed of the soft resin material described above.

  On the front surface of each wall plate portion 35, a contact convex portion 35b having substantially the same shape as the convex portion 35a is formed extending in the vertical direction. Each contact protrusion 35b is in contact with the inner surface of the front wall portion 21a of the lower cover 21 when the lower cover 21 and the upper cover 22 are overlapped and connected to each other (see FIGS. 3 and 11). This is for positioning the front edge portions of the cover 21 and the upper cover 22.

  Next, as shown in FIGS. 2 and 4, the locking mechanism 26 includes a hook (locking member) 40 protruding from the inner surface side of the front wall portion 21a of the lower cover 21 toward the upper cover 22 side, A recess (locking portion) 42 that locks the hook 40 is formed on the inner surface of the front wall portion 22 a of the cover 22.

  As shown in FIGS. 4 and 5, the hook 40 has a claw portion 40 b that protrudes forward from the approximate center of the base member 40 a that is wide in the left-right direction and is attached to the inner surface of the front wall portion 21 a of the lower cover 21. The base member 40a has an upper edge overlapping the end surface (upper end surface) of the front wall portion 21a, and the claw portion 40b projects forward from the center of the upper edge portion to the front wall portion 21a ( (See also FIG. 11). The hook 40 is made of metal or resin, and may be the same material as the lower cover 21 or a different material. Further, the hook 40 may be integrally formed with the lower cover 21.

  In the case of the present embodiment, the hook 40 adjacent to the engagement mechanism 24 is disposed in the concave portion 34b of the positioning member 34 on the upper cover 22 side (see FIGS. 9 and 11), so that the lower cover 21 is covered with the upper cover. It also functions as a positioning portion in the left-right direction when connecting to 22.

  As shown in FIG. 4, the recess 42 has a shape in which the inner surface of the front wall portion 22a of the upper cover 22 is recessed forward, and is formed to extend, for example, in the longitudinal direction of the front wall portion 22a (see FIG. 4). 11). The recess 42 may have a short left and right width dimension such that the claw portion 40b of the hook 40 can be inserted. In this case, the recess 42 may be formed in a portion corresponding to each hook 40.

  Next, as shown in FIG. 2, the fastening portions 28 are screwing portions provided at a total of five locations along the rear edge portion from the left and right side edge portions of the main body housing 14. In each fastening portion 28, the lower cover 21 and the upper cover 22 are fastened and fixed by fixing screws 28 a that are inserted upward from the lower surface side of the lower cover 21 and screwed to the lower surface side of the upper cover 22.

  Next, an example of a procedure for connecting the lower cover 21 and the upper cover 22 constituting the housing structure 10 will be described.

  12 is an explanatory view showing a state in which the front edge portion of the lower cover 21 is positioned with respect to the front edge portion of the upper cover 22, and FIG. 13 shows that the lower cover 21 is moved to the upper cover 22 side from the state shown in FIG. It is explanatory drawing which shows the state which fell to. Here, FIGS. 12A and 13A are cross-sectional views showing the state of the engagement mechanism 24 shown in FIG. 3, and FIGS. 12B and 13B are shown in FIG. 4 is a cross-sectional view showing a state of the locking mechanism 26. FIG.

  When connecting the lower cover 21 and the upper cover 22 to form the main body casing 14 including the casing structure 10, first, as shown in FIG. 12, the upper cover 22 is placed with the upper wall portion 22d facing downward. It is mounted on a mounting table, and the lower cover 21 is aligned with the front edge (front wall 22a) of the upper cover 22 with its front edge (front wall 21a) facing down. Positioning in the left-right direction at this time can be performed by aligning the side walls 21c, 22c of the lower cover 21 and the upper cover 22. In the case of the present embodiment, the base members 40a of the two hooks 40 on the lower cover 21 side adjacent to the two positioning members 34 on the upper cover 22 side are respectively aligned with the concave portions 34b of the positioning member 34, thereby making it more accurate. In addition, positioning in the left-right direction can be easily performed.

  Thereby, in each engagement mechanism 24, each protrusion piece 30 is disposed opposite to each engagement groove 32 (see FIG. 12A), and in each locking mechanism 26, the claw portion 40b of each hook 40 is formed in each recess 42. They are arranged opposite to each other (see FIG. 12B).

  Subsequently, as shown in FIG. 13, the lower cover 21 is tilted in a direction overlapping the upper cover 22 with the front edge portion as the center. Then, in each engagement mechanism 24, each protruding piece 30 is gradually engaged with each engagement groove 32 (see FIG. 13A), and in each locking mechanism 26, the claw portion 40b of each hook 40 is in each recess. It is gradually inserted into 42 (see FIG. 13B).

  Finally, the lower cover 21 is placed on the upper cover 22 so as to lie on top of each other, so that each protrusion 30 is engaged with each engagement groove 32 in each engagement mechanism 24 (see FIG. 3 and FIG. 3). In each locking mechanism 26, the claw portion 40b of each hook 40 is locked to each recess 42 (see FIGS. 4 and 11). As a result, the front edge portion of the lower cover 21 and the front edge portion of the upper cover 22 are connected to each other by the housing structure 10. That is, the front edge portion of the lower cover 21 and the front edge portion of the upper cover 22 are connected in a direction overlapping each other by the claw portion 40b of the hook 40 being locked to the concave portion 42, and are prevented from coming off in the vertical direction. At the same time, the protruding pieces 30 are engaged with the engaging grooves 32, so that relative positional shifts in the direction along the front edge of the main body housing 14 (left and right direction) are restricted.

  In this state, the front wall portion 21 a of the lower cover 21 is inserted and disposed between the front wall portion 22 a of the upper cover 22 and the positioning member 34, and the abutment convex portion 35 b of the positioning member 34 is in front of the lower cover 21. It contacts the inner surface of the wall 21a (see FIGS. 3 and 11). As a result, the relative displacement between the front edge portion of the lower cover 21 and the front edge portion of the upper cover 22 is also restricted in the direction orthogonal to the front edge portion of the main body casing 14 (front-rear direction). .

  Next, the fastening part 28 is comprised by fastening the side edge part and rear edge part of the lower cover 21 and the upper cover 22 which connected between front edge parts as mentioned above with the fixing screw 28a (refer FIG. 2). As a result, the lower cover 21 and the upper cover 22 are also connected with respect to the side edge portion and the rear edge portion of the main body casing 14, and as a result, the lower cover 21 and the upper cover 22 are completely connected to each other. 14 is formed.

  In this case, in the housing structure 10 according to the present embodiment, the front cover of the lower cover 21 is provided with a protruding piece 30 that protrudes rearward and intersects the direction along the front cover. An engagement groove 32 for engaging the protruding piece 30 is provided at the front edge portion of 22, and a hook 40 protruding toward the upper cover 22 side is provided at the front edge portion of the lower cover 21, while the upper cover The front edge of 22 is provided with a recess 42 for locking the hook 40. The lower cover 21 and the upper cover 22 are connected in the direction in which they overlap each other when the hook 40 is locked to the recess 42, and the projecting piece 30 is engaged with the engagement groove 32, thereby the front edge portion. The relative positional deviation in the left-right direction along the line is regulated.

  Therefore, in the main body casing 14 configured with such a casing structure 10, since the protruding piece 30 is engaged with the engaging groove 32, the left and right sides at the front edge portions of the lower cover 21 and the upper cover 22 are arranged. The relative displacement of the direction is restricted. As a result, for example, as shown in FIG. 14 (A), the user performs an operation of gripping and lifting the front edge side of the main body housing 14 from the state of being placed on a desk or the like, and the result is shown in FIG. 14 (B). Thus, even when an external force such as twisting or twisting is applied to the main body casing 14, the positional displacement between the lower cover 21 and the upper cover 22 does not occur. It returns to the initial state as shown in (A). For this reason, the main body casing 14 is distorted, and does not become unstable due to locking when placed on a placement surface such as a desk, so that deterioration in product quality can be suppressed. In addition, in the housing structure 10, a locking mechanism 26 including a hook 40 and a recess 42 is provided on the front edge portion where the engaging mechanism 24 including the protruding piece 30 and the engaging groove 32 is provided. As a result, the lower cover 21 and the upper cover 22 are firmly connected with high connection strength in a direction in which they overlap each other, so that when the external force is applied as described above, the lower cover 21 and the upper cover 22 are connected in the connecting direction. It will not be separated. 14 (A) and 14 (B) are front sectional views schematically showing the connecting structure at the front end portions of the lower cover 21 and the upper cover 22, and the locking structure of the locking mechanism 26 is shown. For the sake of clarity, the insertion direction of the hook 40 with respect to the concave portion 42 is shown in the left-right direction instead of the front-rear direction shown in FIG.

  At this time, in the housing structure 10, a lateral displacement prevention structure (engagement mechanism 24) by the protruding piece 30 and the engagement groove 32 is provided at two locations along the front edge portion of the main body housing 14. Therefore, higher rigidity than the structure provided in one place is obtained. Of course, the engagement mechanisms 24 may be provided at three or more positions on the front edge, but in this case, it becomes difficult to manage the tolerance between the protruding piece 30 and the engagement groove 32 of each engagement mechanism 24. In consideration of assembly efficiency and strength, it is preferable to provide them at two locations.

  In the housing structure 10, the engaging groove 32 or at least the convex portion 35 a provided on the inner surface of the engaging groove 32 is formed of a material softer than the protruding piece 30. Thus, when the protruding piece 30 is engaged with the engaging groove 32, the inner surface of the engaging groove 32 or the convex portion 35a provided on the inner surface can be compressed and deformed by the protruding piece 30. Such tolerance can be set as small as possible. In other words, even if there is some assembly tolerance between the lower cover 21 and the upper cover 22, the convex portion 35a can be crushed and absorbed. As a result, it is possible to more reliably prevent the relative positional shift between the lower cover 21 and the upper cover 22 in the left-right direction, and to reliably prevent the occurrence of rattling.

  In the housing structure 10, the direction in which the protruding piece 30 is engaged with the engaging groove 32 and the direction in which the claw portion 40 b of the hook 40 is engaged with the recess 42 are both set in the front-rear direction. For this reason, when connecting the lower cover 21 and the upper cover 22, as shown in FIG.12 and FIG.13, after aligning the front-and-rear direction position of each front edge part, it overlaps so that both may close a shell. Thus, the engaging operation of the protruding piece 30 with respect to the engaging groove 32 and the engaging operation of the hook 40 with respect to the claw portion 40b with respect to the concave portion 42 can be performed simultaneously, so that the assembling work is easy and the working efficiency is improved.

  The locking mechanism 26 for preventing separation in the connecting direction (vertical direction) between the lower cover 21 and the upper cover 22 is other than the structure using the hook 40 and the recess 42, for example, as shown in FIG. A locking mechanism 52 that locks using a screw 50 that fastens with a play that can be displaced in the left-right direction between the lower cover 21 and the upper cover 22 may be used.

  The locking mechanism 52 shown in FIG. 15 includes a hole portion (locking portion) formed in the bottom portion of the hole portion 54 from an upward hole portion 54 formed on the inner side (rear side) of the front wall portion 21 a of the lower cover 21. ) And a screw (locking member) 50 that is screwed into the inside of the front wall portion 22a of the upper cover 22 through 54a. In the configuration example shown in FIG. 15, the screw portion 50 a of the screw 50 is inserted into the hole portion 54 a and the washer 56 that contacts the lower surface of the upper cover 22, and is screwed to the upper cover 22 side. The shaft portion 50b of the screw 50 that lands on the seating surface of the washer 56 has an outer diameter smaller than the inner diameter of the hole portion 54a, so that the shaft portion 50b has play that can move inside the hole portion 54a. On the other hand, the head 50c of the screw 50 has an outer diameter larger than the inner diameter of the hole 54a, thereby locking the head 50c to the outer peripheral edge of the hole 54a.

  Therefore, in such a locking mechanism 52, the screw 50 is in a state where the head portion 50c protrudes to the lower cover 21 side by screwing the screw portion 50a to the upper cover 22, and in this state the head portion 50c is engaged with the hole 54a through which the screw portion 50a and the shaft portion 50b are inserted, thereby connecting the lower cover 21 and the upper cover 22 in the vertical direction and preventing them from coming off. At this time, since the screw 50 has a play that can move between the shaft portion 50b and the hole portion 54a with respect to the lower cover 21, as shown in FIG. 14B, the main body housing 14 is twisted or twisted. Even when an external force is applied, the screw 50 simply returns to the initial state as shown in FIG. 15 after releasing the external force only by moving the shaft portion 50b within the hole portion 54a. As a result, the same effect as the above-described locking mechanism 26 can be obtained in the locking mechanism 52.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.

  For example, in the above embodiment, the protruding piece 30 constituting the engaging mechanism 24 is provided in the lower cover 21 and the engaging groove 32 is provided in the upper cover 22, but the protruding piece 30 is provided in the upper cover 22. Of course, the engaging groove 32 may be provided in the lower cover 21. Similarly, a hook 40 (screw 50) that is a locking member constituting the locking mechanism 26 (52) is provided in the lower cover 21, and a concave portion 42 (hole portion 54a) that is a locking portion is provided in the upper cover 22. Although the configuration is exemplified, the hook 40 (screw 50) may be provided on the upper cover 22 and the recess 42 (hole 54a) may be provided on the lower cover 21.

  In the above embodiment, the engaging mechanism 24 and the locking mechanism 26 (52) are provided at the front edge of the main body housing 14, but are provided at other edges such as the side edge and the rear edge. Also good. However, in the electronic device 12 of the notebook type PC as shown in FIG. 1, when the user grips and lifts the main body casing 14 or opens the display casing 20 from the main body casing 14, Since an external force of twisting or twisting is easily applied, it is desirable to provide the engaging mechanism 24 and the locking mechanism 26 (52) at least at the front edge portion. In other words, in the housing structure 10 according to the above embodiment, the rear edge portion and the side edge portion other than the front edge portion are screwed and fixed by the fastening portion 28, but these rear edge portion and side edge portion are Since there is almost no fear of causing a large misalignment in the left-right direction as in the front edge portion, even if the fastening portion 28 is used, no serious problem occurs.
