Description

  The present invention relates to a vehicle front structure of an automobile in which headlamps are disposed in the vicinity of both side surfaces of a front portion.

  In order to improve visibility when traveling at night or the like, headlamps are arranged in the vicinity of both side surfaces of the front portion of the vehicle. The headlamp is generally configured to be attached to a structural member in the front portion of the vehicle. For example, in Patent Document 1, the structure of the front portion of the vehicle is formed by a metallic coupling member coupled to the housing of the headlight (headlamp). A headlamp is connected to the front end portion of the front side frame as a member and the front end portion of the apron reinforcement.

  By the way, when the collision object is a pedestrian at the time of collision between the vehicle and the collision object, a load is applied to the pedestrian from the vehicle. If the collision point of the collision object (pedestrian) is in the vicinity of the headlamp of the vehicle, the leg of the pedestrian receives a load from the headlamp. For example, in Patent Document 1, since the headlamp is connected to the front end portion of the apron reinforcement, the apron reinforcement exists on the rear side of the headlamp. That is, in the conventional structure as in Patent Document 1, since the structural member in the front part of the vehicle supports the rear side of the headlamp, the pedestrian receives the reaction force (load) from the headlamp. Therefore, it was difficult to reduce the load.

  In order to solve the above problems, the present inventors diligently studied, arranged such that the structural member of the front part of the vehicle does not exist on the rear side of the headlamp, and moved the headlamp to the rear side of the vehicle by a collision (rearward stroke Reached the view that it is most effective. However, the structural member in the front part of the vehicle plays a role of supporting the headlamp and ensuring rigidity in the front part of the vehicle. For this reason, if the structural member is simply removed from the rear side of the headlamp, there is a problem that the support of the headlamp becomes unstable or the rigidity of the front portion of the vehicle is insufficient.

  In view of such a problem, the present invention aims to reduce the load on the pedestrian by moving the headlamp toward the rear side of the vehicle at the time of a collision while ensuring the support stability of the headlamp and the rigidity of the front portion of the vehicle. An object of the present invention is to provide a vehicle front structure that can be used.

  In order to solve the above problems, a typical configuration of a vehicle front structure according to the present invention is a vehicle front structure of an automobile in which headlamps are disposed in the vicinity of both side surfaces of the front, An upper horizontal member extending in the vehicle width direction between the headlamps, a lower horizontal member extending in the vehicle width direction below the upper horizontal member at the front portion of the vehicle, and a front end portion connected to the lower horizontal member. The two apron side members extending in the vehicle length direction, the upper end portion is connected to the vicinity of both ends of the upper lateral member, the lower end portion is connected to the apron side member, and between the upper lateral member and the lower lateral member There are two lamp support braces extending in the vehicle height direction, and a fixing member that is passed through the gap between the lamp support brace and the head lamp and connects them, and the head lamp is connected to the inside of the vehicle via the fixing member. Lamp support The lamp support brace is curved so as not to interfere with the headlamp except at the support point of the headlamp when viewed from the front of the vehicle. It is characterized by.

  In the above configuration, since the upper lateral member extends between the headlamps and the lamp support brace is curved so as not to interfere with the headlamp, there is no structural member disposed behind the headlamp. That is, in the present invention, the lamp support member, the lamp support brace, and the like that are disposed behind the headlamp in the conventional structure are excluded from the rear of the headlamp. As a result, the headlamp can be easily moved (stroked) to the rear side of the vehicle at the time of a collision, so that the load on the pedestrian can be reduced. Further, by connecting the respective members as in the above configuration, in the vehicle front view, a frame shape having the upper lateral member and the lower lateral member as the upper and lower sides and the apron side member and the lamp support brace as the two side sides is obtained. Since it is formed, the rigidity of the front portion of the vehicle can be ensured. In particular, since the lamp support brace is connected to the apron side member extending in the vehicle length direction on the side of the frame shape, the rigidity against the force received from the front of the vehicle at the time of collision is increased, and deformation of the side is suitably suppressed. It becomes possible.

  Further, the vehicle lamp inner side of the headlamp is supported by the lamp support brace and the vehicle outer side is supported by the side member, thereby ensuring the headlamp support stability. In particular, when the lamp support brace and the headlamp are connected via the fixing member, the fixing member becomes a fragile portion and is broken by an impact at the time of a collision, and the connection between the lamp support brace and the headlamp is disconnected. Accordingly, the headlamp after the collision is supported only on the outer side of the vehicle by the side member, and the inner side of the vehicle moves toward the rear side of the vehicle with a support point on the outer side of the vehicle as an axis. Therefore, according to the above-described configuration, it is possible to reduce the load on the pedestrian by moving the headlamp toward the rear side of the vehicle at the time of collision while securing the support stability of the headlamp and the rigidity of the front portion of the vehicle. It becomes possible.

  In the headlamp, at least the vicinity of the upper part and the lower part of the surface other than the front surface outside the vehicle is supported by the front end of the side member, and at least the vicinity of the lower part is supported by the fixing member on the front surface of the lamp support brace inside the vehicle. Good.

  According to such a configuration, the vehicle outer side of the headlamp is supported in the vicinity of the upper part and the vicinity of the lower part, thereby further improving the support stability, and by being supported on a surface other than the front surface, Cutting (breaking) can be prevented. On the other hand, the vehicle inner side of the headlamp is supported on the front surface of the lamp support brace in the vicinity of the lower portion, so that the fixing member is easily subjected to an impact at the time of collision and is more easily cut. For this reason, it becomes possible to further ensure the movement of the headlamp to the vehicle rear side at the time of a collision.

  The fixing member may be a tab that is provided on the vehicle inner side of the headlamp and protrudes inward of the vehicle when viewed from the front of the vehicle. Thereby, since the headlamp and the fixing member are integrated, the number of parts is not increased.

  In the vicinity of the connecting portion between the apron side member and the lamp support brace, a reinforcing member connected to them may be provided. Thereby, the connection strength between the apron side member and the lamp support brace can be increased. Therefore, it is possible to further improve the rigidity of the side edges of the frame shape made of these, and to further suppress deformation.

  According to the present invention, a vehicle capable of reducing the load on a pedestrian by moving the headlamp to the rear side of the vehicle at the time of a collision while ensuring the support stability of the headlamp and the rigidity of the front portion of the vehicle. A front structure can be provided.

It is a perspective view which shows the front part of the vehicle which has the vehicle front part structure concerning this embodiment. FIG. 2 is an enlarged perspective view of the vicinity of the headlamp in FIG. 1. FIG. 3 is a front view of FIG. 2. It is a perspective view of a headlamp. It is a top view of the vehicle front part which shows the movement of the headlamp at the time of a collision.

  FIG. 1 is a perspective view showing a front portion of a vehicle having a vehicle front portion structure according to the present embodiment. FIG. 2 is an enlarged perspective view of the vicinity of the headlamp 110a in FIG. FIG. 3 is a front view of FIG. For easy understanding, the hood lock brace 160 (see FIG. 3) is not shown in FIG. 1, and the front fender panel 170 and the cowl side panel 180 are not shown in FIG. Further, since the front part of the vehicle and the headlamps 110a and 110b are symmetrical with respect to the hood lock brace 160, FIGS. 2 to 5 illustrate the right headlamp 110a and its vicinity in the vehicle front view. explain.

  As shown in FIG. 1, headlamps 110a and 110b are respectively disposed in the vicinity of both side surfaces at the front of a vehicle 100 (automobile). Thereby, visibility improvement at the time of night driving etc. can be aimed at.

  At the front portion of the vehicle 100, a hood lock member 120 that is an upper lateral member extending in the vehicle width direction between the headlamps 110a and 110b, and a lower lateral member that extends below the hood lock member 120 in the vehicle width direction. A lower cross member 130 is provided. In the present embodiment, the hood lock member 120 is illustrated as the upper horizontal member, and the front lower cross member 130 is illustrated as the lower horizontal member. However, the present invention is not limited to this, and other members include the upper horizontal member and the lower horizontal member. It is good.

  Front end portions 142a and 142b of two apron side members 140a and 140b are connected to the vicinity of both ends of the front lower cross member 130. In the apron side members 140a and 140b, extension portions 144a and 144b extend rearward in the vehicle length direction from the front end portions 142a and 142b at the front portion of the vehicle.

  Further, near the both ends of the hood lock member 120, upper ends of two lamp support braces 150a and 150b extending in the vehicle height direction are connected between the hood lock member 120 and the front lower cross member 130. The lower end portions of the lamp support braces 150a and 150b are connected to the apron side members 140a and 140b (strictly speaking, their front end portions 142a and 142b).

  With the above configuration, the front part of the vehicle has the hood lock member 120 and the front lower cross member 130 as upper and lower sides, and the two apron side members 140a and 140b and the two lamp support braces 150a and 150b in the vehicle front view. A frame shape with both sides is formed. Thus, the rigidity of the front part of the vehicle is ensured because the framework of the front part of the vehicle has a frame shape. In particular, as in this embodiment, the lamp support braces 150a and 150b are connected to the apron side members 140a and 140b extending in the vehicle length direction, so that the rigidity against the force received from the front of the vehicle at the time of a collision can be increased. It becomes possible to suitably suppress the deformation of the side.

  Further, in the present embodiment, reinforcing members 190a and 190b connected to the apron side member 140a and the lamp support brace 150a are provided in the vicinity of the connection portion between the apron side member 140a and the lamp support brace 150a and in the vicinity of the connection portion between the apron side member 140b and the lamp support brace 150b. It has been. Thereby, the connection strength between each apron side member and each lamp support brace can be improved. Therefore, the rigidity of the side of the frame shape described above can be further increased, and the deformation can be further suppressed.

  Further, in the present embodiment, as shown in FIG. 3, the lamp support brace 150a is curved so as not to interfere with the headlamp 110a except for a support point (a connecting portion 116c described later) of the headlamp 110a in a front view of the vehicle. . Due to the curvature of the lamp support brace 150a and the above-described hood lock member 120 extending between the headlamps 110a and 110b, the structural member at the front of the vehicle is not disposed behind the headlamp 110a. Therefore, as will be described later, the movement (stroke) of the headlamp 110a toward the vehicle rear side during a collision is easy.

  FIG. 4 is a perspective view of the headlamp 110a. As shown in FIG. 4, the headlamp 110a is configured by providing a lamp cover 114 on the front surface of a lamp housing 112 provided with a lamp unit (not shown) and serving as a main body of the headlamp 110a. In this embodiment, the lamp housing 112 is provided with connecting portions 116a, 116b, and 116c.

  Specifically, the connecting portion 116a is provided in the vicinity of the lower portion of the lamp housing 112 outside the vehicle, and the connecting portion 116b is provided in the vicinity of the upper portion of the lamp housing 112 outside the vehicle. Then, as shown in FIG. 2, the connecting portion 116a is connected to the front end portion of the front fender panel 170, and the connecting portion 116b is connected to the front end portion of the cowl side panel 180. It is supported by a front fender panel 170 and a cowl side panel 180 which are side members constituting the side surface. Thereby, the vehicle outer side of the headlamp 110a is stably supported.

  In particular, in the present embodiment, the connecting portion 116a is disposed so as to protrude downward from the headlamp 110a in the vehicle, and the connecting portion 116b is disposed so as to protrude rearward from the headlamp 110a. According to such a configuration, the headlamp 110a is supported on the upper surface on the outer side of the vehicle and on the side surface on the lower side. That is, the headlamp 110a is supported on a surface other than the front surface outside the vehicle. Thereby, as will be described in detail later, cutting (destruction) due to an impact at the time of collision can be suitably prevented.

  On the other hand, the connecting portion 116c is provided in the vicinity of the lower portion inside the vehicle of the headlamp 110a (specifically, the lamp housing 112), and is connected between the lamp support brace 150a and the headlamp 110a so as to protrude inward of the vehicle when viewed from the front of the vehicle. It is a tab passed over the gap. That is, the connection part 116c is a fixing member in the present embodiment. Thereby, since the headlamp 110a and the fixing member are integrated, the number of parts is not increased.

  As shown in FIG. 2, by connecting the connection portion 116c to the lamp support brace 150a, the vehicle inside of the headlamp 110a is supported by the lamp support brace 150a via the connection portion 116c (fixing member). In particular, in the present embodiment, the connecting portion 116c is disposed so as to contact the front surface of the lamp support brace 150a, and the vehicle inside of the headlamp 110a is supported on the front surface of the lamp support brace 150a. Thereby, as will be described later, the connection portion 116c is easily subjected to an impact at the time of collision, and the cutting is facilitated.

  FIG. 5 is a top view of the front portion of the vehicle showing the movement of the headlamp 110a during a collision. Before the collision, that is, at the normal time, as described above, the headlamp 110a is supported on the front fender panel 170 and the cowl side panel 180 by the connecting portion 116a (see FIG. 2) and the connecting portion 116b on the outside of the vehicle, and connected on the inside of the vehicle. It is supported by the lamp support brace 150a by the portion 116c and is in the state shown by the solid line in FIG.

  In the above state, when a collision with a pedestrian as a colliding body occurs and an impact is received from the direction of the white arrow, the headlamp 110a is pushed into the white arrow. As a result, the force in the same direction is also applied to the connecting portion 116c, and the vicinity of the portion adjacent to the headlamp 110a is broken (broken).

  When the connection portion 116c is broken, the connection between the lamp support brace 150a and the headlamp 110a is cut off, so that the headlamp 110a is supported only on the outside of the vehicle. Then, the inside of the vehicle of the headlamp 110a moves (strokes) around the support point on the outside of the vehicle so as to rotate toward the rear of the vehicle in the direction of the thick arrow in FIG. 5, and the two-dot chain line in FIG. It will be in the state shown.

  Accordingly, by connecting the lamp support brace 150a and the headlamp via the connection part 116c (fixing member) as in the present embodiment, the connection part 116c becomes a fragile part and the headlamp 110a is affected by an impact at the time of collision. The movement to the vehicle rear side can be ensured, and the load on the pedestrian can be reduced. Further, the connection portion 116c is brought into contact with the front surface of the lamp support brace 150a, and the vehicle inner side of the headlamp 110a is supported on the front surface of the lamp support brace 150a, thereby promoting breakage of the connection portion 116c due to an impact at the time of collision. Therefore, the headlamp 110a and the lamp support brace 150a can be easily cut.

  In the present embodiment, the vicinity of the upper portion and the lower portion of the head lamp 110a outside the vehicle is supported by the side member, and the vicinity of the lower portion inside the vehicle is supported by the lamp support brace 150a. However, such a configuration is merely an example. However, the present invention is not limited to this. Therefore, the vehicle outer side and the vehicle inner side of the headlamp 110a may be supported at other locations.

  However, troubles due to the increase of the support point on the vehicle outer side of the headlamp 110a are unlikely to occur, but if the support point is increased too much on the vehicle inner side of the headlamp 110a, the support strength increases too much, and the head at the time of the collision is increased. There is a possibility that the movement of the lamp 110a toward the vehicle rear side may be hindered. For this reason, it is preferable that only one place is supported inside the vehicle of the headlamp 110a as in the present embodiment.

  In the present embodiment, the front fender panel 170 and the cowl side panel 180 are illustrated as side members for supporting the vehicle outer side of the headlamp 110a. However, the present invention is not limited to this, and the vehicle outer side of the headlamp 110a is not limited to this. It may be supported by the side member. Furthermore, the fixing member does not necessarily need to be the connecting portion 116c integrated with the lamp cover 114 (head lamp 110a), and may be a separate member.

  As described above, according to the vehicle front structure according to the present embodiment, since there is no structural member arranged behind the headlamp 110a, the headlamp 110a can easily move to the vehicle rear side in the event of a collision (stroke it can. Then, by connecting the lamp support brace 150a and the headlamp 110a by the connecting portion 116c, which is a fixing member, the fixing member is broken by an impact at the time of collision, and the headlamp 110a is reliably moved to the rear side of the vehicle. Is possible. Further, the hood lock member 120, the front lower cross member 130, the apron side member 140a, and the lamp support brace 150a form a frame shape, so that the rigidity of the front portion of the vehicle can be secured and the deformation can be suitably suppressed. . Further, the vehicle lamp inner side of the headlamp 110a is supported by the lamp support brace 150a and the vehicle outer side is supported by the side member, so that the support stability of the headlamp 110a is ensured. Therefore, it is possible to reduce the load on the pedestrian by moving the headlamp 110a toward the rear side of the vehicle at the time of collision while securing the support stability of the headlamp 110a and the rigidity of the front portion of the vehicle.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.
