Description

  The present invention relates to a vehicular bumper that is integrally provided with a cover body that matches the shape of a hook cover that can open and close a hook hole formed in the bumper.

  Conventionally, the above-mentioned vehicle bumpers include those shown in Patent Documents 1 and 2 below.

  According to the thing of the said patent document 1, the bumper is provided with the lower bumper besides being mutually formed and connected mutually. Above these, a lamp hole for attaching a lamp is formed in the lower bumper among the lower bumpers. On the other hand, a lamp cover for closing the lamp hole is fixed to the upper bumper so as to be removable. The lamp cover protrudes downward from the lower end of the upper bumper.

  Here, the bumper having the above configuration is a case where a lamp is not attached. On the other hand, when attaching a lamp to the bumper, first, the lamp cover is removed from the upper bumper. Then, the lamp is inserted into the lamp hole opened by the removal and attached to the upper bumper.

Moreover, according to the thing of the said patent document 2, the bumper is provided with the bumper main body in which the hook hole which makes it possible to penetrate the hook for vehicle pulling was formed. A cover body whose shape matches a hook cover that can open and close the hook hole is formed separately from the bumper body. The cover body is temporarily fixed to the back side of the bumper body. Then, when the surface of the bumper main body is painted, the cover body is also painted to form the hook cover.

  By the way, in the thing of the said patent document 1, as above-mentioned, the lamp cover for closing the lamp hole formed in the lower bumper protrudes toward the downward direction from the upper bumper. For this reason, there is an inconvenience that an outer dimension of the combination of the upper bumper and the lamp cover is increased, and a mold used for forming the combination is increased.

  On the other hand, in the thing of the said patent document 2, the bumper main body with which a bumper is provided, and a cover body are mutually shape | molded separately. Moreover, when the bumper body and the cover body are painted, it is required to temporarily fix the cover body to the bumper body. For this reason, the painting operation on the bumper tends to be complicated.

  Further, as described above, the cover body is temporarily fixed to the back side of the bumper body. For this reason, at the time of the painting, the surfaces of the bumper body and the cover body are separated from each other, and a difference tends to occur between the painting conditions of these surfaces. Therefore, it is difficult to match the colors of the coatings between these surfaces.

  As a result, when a hook cover formed by painting the cover body is attached to the bumper body and the hook hole is closed, a sense of incongruity occurs between the bumper body and the hook cover in terms of color. There is a fear.

  The present invention has been made paying attention to the above situation, and an object of the present invention is to provide a cover body whose shape matches a hook cover that can open and close a hook hole formed in a painted portion of a bumper. In the bumper provided, the mold for the bumper can be made small, and the painting work on the bumper can be easily performed.

  Another object of the present invention is to make it possible to easily perform color matching of the coatings on the surfaces of the painted portion of the bumper and the cover body.

The invention of claim 1 is provided with a paint hole 6 to be coated with the surface 5 and a non-painted part 8 with the surface 7 to be unpainted, and a hook hole 12 that allows the vehicle towing hook 11 to pass therethrough. In the vehicle bumper formed in the painted portion 6 and having the opening 15 in the non-painted portion 8,
A cover body 18 having a matching shape is provided on a hook cover 17 capable of opening and closing the hook hole 12, and the cover body 18 is disposed in the opening 15 in a front view of the bumper 2 (FIGS. 1 and 3). The cover body 18 is displaced outwardly or inwardly from the surface 7 of the non-painted portion 8, and the cover body 18 is detachably and integrally fixed to the painted portion 6 or the non-painted portion 8. Is.

  According to a second aspect of the present invention, in addition to the first aspect of the invention, the cover body 18 is disposed outside the surface 7 of the non-painted portion 8 so as to be detachable integrally with the painted portion 6. Adhering, forming a shelf 24 along the boundary line between the painted portion 6 and the non-painted portion 8, and an outer edge portion of the masking material 25 covering the surface of the non-painted portion 8 when coating the painted portion 6 A notch 32 is formed in a part of the shelf 24 so as to be able to be locked to the shelf 24, and the cover body 18 to the painted portion 6 is viewed from the front of the bumper 2 (FIG. 3). The fixing portion 26 side and the notch 32 are arranged at the same place.

  In addition to the invention of claim 1 or 2, the invention of claim 3 is the one in which the hook hole 12 and the cover body 18 are arranged at substantially the same height in the front view of the bumper 2 (FIG. 1). It is.

  In this section, the reference numerals appended to the above terms are not to be construed as limiting the technical scope of the present invention to the section “Example” described later or the contents of the drawings.

  The effects of the present invention are as follows.

The invention of claim 1 is provided with a painted portion whose surface is to be painted and a non-painted portion whose surface is not to be painted, and a hook hole which allows a vehicle tow hook to pass therethrough is formed in the painted portion. In the vehicle bumper having an opening in the non-painted part,
A cover body having a matching shape is provided on a hook cover that can open and close the hook hole, and the cover body is disposed in the opening in a front view of a bumper, and the cover body is disposed more than the surface of the non-painted portion. The cover body is detachably attached to the painted part or the non-painted part so as to be detachable in an outward or inward direction.

  That is, as described above, the cover body is disposed in the opening formed in the non-painted portion when the bumper is viewed from the front.

  For this reason, in the front view of the bumper, since the cover body does not protrude from the non-painted part, the outer shape of the bumper can be suppressed to be smaller than that of the lamp cover protruded as in Patent Document 1, and the bumper The mold can be made smaller.

  Further, as described above, the cover body fixed to the painted portion or the non-painted portion is disposed outward or inward from the surface of the non-painted portion.

  For this reason, when coating each surface of the painted part and the cover body, it is not necessary to temporarily fix the cover body as in Patent Document 2, and the surface of the non-painted part is masked. When the masking operation for covering with is performed, since the cover body is displaced from the surface of the non-painted portion, the cover body is prevented from becoming an obstacle. Therefore, the masking operation can be easily performed, and thereby the painting operation to the bumper can be easily performed.

  According to a second aspect of the present invention, the cover body is disposed outwardly from the surface of the non-painted part, and is integrally fixed to the paint part so as to be removable, and a boundary between the paint part and the non-paint part. A shelf is formed along the line, and an outer edge portion of the masking material that covers the surface of the non-painted portion at the time of painting on the painted portion can be locked to the shelf.

  For this reason, when performing the masking operation, simply placing the masking material between the surface of the non-painted part and the cover body, and locking the outer edge of the masking material to the shelf, The masking operation is completed. Therefore, this masking operation can be easily performed, and thereby the coating operation to the bumper can be performed more easily.

  In addition, a notch is formed in a part of the shelf, and the fixing portion side of the cover body to the paint portion and the notch are arranged at the same position in front view of the bumper.

  For this reason, it is prevented that the shelf is present in the front and rear direction of the fixing portion side of the cover body to the painted portion, that is, between the fixing portion side and the shelf portion of the cover body in the front-rear direction. It is possible to prevent the concave portion from being formed on the surface. Therefore, when the bumper is injection-molded, for example, a slide mold that can move in the longitudinal direction of the bumper for molding the concave portion is not necessary, and the bumper can be molded more easily.

  According to a third aspect of the present invention, the hook hole and the cover body are disposed at substantially the same height in a front view of the bumper.

  Here, the painting work on the generally long bumper is generally as follows. That is, the nozzle is moved laterally along the bumper from one end side in the longitudinal direction of the bumper, and the paint is sprayed by the nozzle toward the bumper during the movement. When the nozzle reaches the other end side of the bumper, the nozzle is moved downward substantially by the coating width of the nozzle. Next, the nozzle is moved in the lateral direction opposite to the above, and the paint is sprayed by the nozzle toward the bumper during the movement. When this nozzle reaches the one end side of the bumper, the nozzle is moved downward by substantially the coating width of the nozzle. Thereafter, the bumper is painted by repeating the above operation.

  For this reason, as described above, when the hook hole and the cover body are arranged at substantially the same height in front view of the bumper, the surface of the coating portion around the hook hole, the surface of the cover body, and The difference between each coating condition can be reduced. Therefore, the color matching of the coating can be easily performed for each of these surfaces.

  The present invention relates to a bumper for a vehicle, and a bumper having a cover body whose shape matches a hook cover capable of opening and closing a hook hole formed in a painted portion of the bumper, and making the mold of the bumper small. In order to realize the object of facilitating the painting work on the bumper, the best mode for carrying out the present invention is as follows.

  That is, the vehicle bumper includes a painted portion whose surface should be painted and a non-painted portion whose surface should be unpainted. A hook hole that allows the vehicle towing hook to pass therethrough is formed in the painted portion, and an opening is formed in the non-painted portion.

  A cover body whose shape matches a hook cover that can open and close the hook hole is provided. In the front view of the bumper, the cover body is disposed in the opening, and the cover body is displaced outward or inward from the surface of the non-painted portion, so that the cover body is the painted portion. Alternatively, it is integrally fixed to the non-painted part so as to be removable.

  In order to explain the present invention in more detail, an embodiment thereof will be described with reference to the accompanying drawings.

  In the figure, reference numeral 1 denotes a vehicle body exemplified by an automobile, and reference numeral 2 denotes a front bumper that covers the front surface of the vehicle body 1 from the front and is supported by the vehicle body 1. Specifically, the bumper 2 is an intermediate molded product immediately before the bumper that is a finished product. In addition, an arrow Fr in the drawing indicates the front in the traveling direction of the vehicle.

  The bumper 2 is entirely made of resin and is injection-molded by front and rear molds. The bumper 2 extends long in the width direction of the vehicle body 1, that is, extends horizontally. The bumper 2 includes a painted part 6 whose surface 5 is to be painted by a paint 4 sprayed from a nozzle 3 actuated by a robot, and a non-painted part 8 whose surface 7 should be left unpainted. Yes. 1 and 3, the plain portion corresponds to the painted portion 6, and the satin pattern portion corresponds to the non-painted portion 8. In addition, the said coating means top coating after undercoating or intermediate coating, and undercoating or intermediate coating may be performed also in the non-coating part 8. FIG.

  A hook hole 12 that allows the hook 11 used when the vehicle is pulled forward to pass therethrough is formed in the paint portion 6. The hook 11 penetrating the hook hole 12 can be attached to and detached from the front end portion of the vehicle body 1 by a fastener 13. On the other hand, the non-painted portion 8 is formed with an opening 15 penetrating the non-painted portion 8 in the longitudinal direction of the vehicle body 1, and this opening 15 is used for reducing the weight of the bumper 2 or for work. The

  When the bumper 2 is viewed from the front (FIGS. 1 and 3), the hook hole 12 has a rectangular shape. A resin cover body 18 having a matching shape is provided on a hook cover 17 that can open and close the hook hole 12. The cover body 18 has a rectangular shape that is fitted in the hook hole 12 and closes the hook hole 12. When the cover body 18 closes the hook hole 12, the cover body 18 is detachably locked to the painted portion 6 by a known locking tool 19 such as a claw fitting.

  The entire cover body 18 is disposed in the opening 15 in a front view of the bumper 2 (FIGS. 1 and 3). The surface 20 of the cover body 18 is substantially parallel to the surface 5 of the painted portion 6 in the vicinity of the upper portion of the cover body 18. Further, the cover body 18 is disposed so as to be deviated outward (frontward) from the surface 7 of the non-painted portion 8, and is integrally and detachably attached to the painted portion 6 by a resin stay 21. It is fixed. Further, a handle 22 is formed integrally with the stay 21.

  If the stay 21 and the handle 22 are pinched with fingers and twisted, the stay 21 and the stay 21 are easily fixed to the painted portion 6 and the cover body 18, respectively. As shown by the middle one-dot chain line, the hook cover 17 is formed.

  A shelf 24 is integrally formed on the bumper 2 along a boundary line between the surface 5 of the painted portion 6 and the surface 7 of the non-painted portion 8. The shelf 24 has a narrow groove shape. When coating the surface 5 of the painted portion 6, the surface 7 of the non-coated portion 8 is covered with a sheet-like masking material 25, and at this time, the outer edge portion of the masking material 25 is pushed into the groove of the shelf portion 24. Is locked.

  The stay 21 protrudes downward from the lower edge of the cover body 18, and the protruding end is integrally fixed to the vicinity of the lower opening edge of the opening 15 and the shelf 24. That is, the fixing portion 26 of the cover body 18 through the stay 21 in the painted portion 6 is disposed in the vicinity of the opening edge portion of the opening 15 and the shelf portion 24.

  In the front view of the bumper 2 (FIG. 1), the hook hole 12 and the cover body 18 are disposed at substantially the same height.

  The painted portion 6, the non-painted portion 8, the cover body 18, the locking tool 19, the stay 21, and the handle 22 of the bumper 2 are integrally formed with each other by a rear die before forming the molding die. Thereafter, the non-painted portion 8 of the bumper 2 is covered with the masking material 25, and the outer edge portion of the masking material 25 is locked to the shelf portion 24. Then, the surface 5 of the painted portion 6 and the surface 20 of the cover body 18 are painted with the paint 4 from the nozzle 3, and then the cover body 18 is removed to form the hook cover 17. A bumper is formed. A license plate 29 is provided to cover the opening 15 in the finished bumper from the outside (front). The license plate 29 is supported by the fastener 30 on the non-painted portion 8 of the bumper.

  As shown by a three-dot chain line in FIG. 4, the cover body 18 is disposed so as to be displaced inward (rearward) from the surface 7 of the non-painted portion 8 so as to be integrated with the non-painted portion 8. It may be fixed. In this case, an opening that allows the paint 4 from the nozzle 3 to reach the surface 20 of the cover body 18 is formed in the portion of the masking material 25 facing the cover body 18.

  According to the above configuration, the cover body 18 having a matching shape is provided on the hook cover 17 that allows the hook hole 12 to be opened and closed, and the cover body 18 is disposed in the opening 15 in a front view of the bumper 2 (FIGS. 1 and 3). The cover body 18 is displaced outwardly or inwardly from the surface 7 of the non-painted portion 8 so that the cover body 18 can be removed from the painted portion 6 or the non-painted portion 8. It is fixed integrally.

  That is, as described above, the cover body 18 is disposed in the opening 15 formed in the non-painted portion 8 in a front view of the bumper 2 (FIGS. 1 and 3).

  For this reason, in the front view of the bumper 2, the outer shape of the bumper 2 can be suppressed to be smaller than that in which the cover body 18 does not protrude from the non-painted portion 8 as compared with the case where the lamp cover is protruded as in Patent Document 1. The molding die for the bumper 2 can be made small.

  In addition, since the entire cover body 18 is disposed in the opening 15, the entire cover body 18 can be molded by the molding die of the opening 15. Therefore, the molding mold of the bumper 2 can be formed. Can be made easier.

  Further, as described above, the cover body 18 fixed to the painted portion 6 or the non-painted portion 8 is disposed outward or inward from the surface 7 of the non-painted portion 8.

  For this reason, it is unnecessary to temporarily fix the cover body 18 as in Patent Document 2 when the surfaces 5 and 20 of the painted portion 6 and the cover body 18 are painted. When the masking operation for covering the surface 7 of the portion 8 with the masking material 25 is performed, the cover body 18 is displaced from the surface 7 of the non-painted portion 8, so that the cover body 18 becomes an obstacle. Is prevented. Therefore, the masking operation can be easily performed, and thereby the painting operation to the bumper 2 can be easily performed.

  Further, as described above, the cover body 18 is disposed outside the surface 7 of the non-painted portion 8 and is detachably fixed to the painted portion 6 so as to be integrated with the painted portion 6. A shelf portion 24 is formed along a boundary line with the portion 8, and an outer edge portion of a masking material 25 that covers the surface of the non-painted portion 8 at the time of painting on the painted portion 6 can be locked to the shelf portion 24. I try to do it.

  For this reason, when the masking operation is performed, the masking material 25 is simply disposed between the surface 7 of the non-painted portion 8 and the cover body 18, and the outer edge of the masking material 25 is placed on the shelf 24. If locked, the masking operation is completed. Therefore, this masking operation can be easily performed, and thereby the coating operation to the bumper 2 can be performed more easily.

  3 and 4, a notch 32 is formed in a part of the shelf 24, and the cover body 18 to the coating portion 6 is viewed from the front of the bumper 2 (FIG. 3). You may arrange | position the said stay 21 and the said notch 32 which are the adhering part 26 side in the mutually same place.

  In this way, the presence of the shelf 24 in the front and rear direction of the stay 21 on the side of the fixing portion 26 of the cover body 18 to the coating portion 6 is prevented. A concave portion is prevented from being formed between the fixing portion 26 side of the body 18 and the shelf portion 24. Therefore, when the bumper 2 is injection-molded, for example, a slide mold that can move in the longitudinal direction of the bumper 2 for molding the concave portion is not necessary, and the bumper 2 can be molded more easily. .

  Further, the fixing portion 26 of the cover body 18 in the painted portion 6 is disposed in the vicinity of the opening edge portion of the opening 15 and the shelf portion 24.

  Here, if the cover body 18 is removed from the painted portion 6 after painting on the cover body 18, a scar of the fixing portion 26 of the cover body 18 remains on the painted portion 6, It is not preferable in appearance.

  Therefore, as described above, the fixing portions 26 of the cover body 18 in the coating portion 6 are arranged in the vicinity of the opening edge portion of the opening 15 and the shelf portion 24, and therefore, after the cover body 18 is removed, Even if a scar is generated on the fixing portion 26 of the cover body 18, it is suppressed from being noticeable. Therefore, according to the bumper 2, a finished bumper having a good appearance can be obtained.

  In addition, as described above, the hook hole 12 and the cover body 18 are disposed at substantially the same height in front view of the bumper 2 (FIGS. 1 and 3).

  Here, the painting work on the above-mentioned horizontally long bumper 2 is as follows. That is, the nozzle 3 is moved laterally along the bumper 2 from one longitudinal end side of the bumper 2, and the paint 4 is sprayed by the nozzle 3 toward the bumper 2 during the movement. When the nozzle 3 reaches the other end side of the bumper 2, the nozzle 3 is moved downward by substantially the coating width by the nozzle 3. Next, the nozzle 3 is moved in the lateral direction opposite to the above, and the paint 4 is sprayed by the nozzle 3 toward the bumper 2 during the movement. When the nozzle 3 reaches one end side of the bumper 2, the nozzle 3 is moved downward by substantially the coating width by the nozzle 3. Thereafter, the painting operation on the bumper 2 is performed by repeating the above operation.

  Therefore, as described above, when the hook hole 12 and the cover body 18 are arranged at substantially the same height in the front view of the bumper 2 (FIGS. 1 and 3), the painted portion around the hook hole 12 The difference between the respective coating conditions for the surface 5 of 6 and the surface 20 of the cover body 18 can be reduced. Therefore, the color matching of the coating can be easily performed for each of the surfaces 5 and 20.

  Further, as described above, the opening 15 of the bumper as a finished product is covered with the license plate 29 from the outside.

  For this reason, even if the scar of the fixing part 26 remains as it is after the cover body 18 is removed, the license plate 29 prevents the appearance of the bumper from being damaged by the scar of the fixing part 26. Therefore, the finished bumper can be molded more easily because the scars on the fixing portion 26 need not be processed with high accuracy.

  Although the above is based on the illustrated example, the vehicle may be a truck or the like. The bumper 2 may be a rear bumper. Further, the cover body 18 may be integrally fixed to the upper opening edge of the opening 15 via the stay 21 or without the stay 21.

It is a front view of a bumper. It is the II-II sectional view taken on the line of FIG. It is the elements on larger scale of FIG. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3.
