Description

The present invention relates to a vehicle structure in which damage to exterior components due to a vehicle collision is less likely to occur (damageability: Damageability is improved) and repairability is improved.
Unless otherwise specified, the vehicle collision referred to in the present specification is mainly a light collision in which the vehicle collides relatively weakly with a pole or an oncoming vehicle at a traveling speed in a low speed region such as slow speed.

As an example of the vehicle structure, there is a vehicle structure described in Patent Document 1.
In the vehicle structure described in the document, the outer plate portions of the first and second exterior parts (eg, the lamp and the bumper cover) are adjacent to each other in the vertical height direction of the vehicle. Here, the second exterior component is attached to the support member having the fragile portion, while the engaging portion provided on the support member engages with the first exterior component. By such engagement, the relative positioning and fixing of the first and second exterior components are achieved.
In this vehicle structure, when the vehicle collides forward and the second exterior component retracts to the vehicle rear side due to the input of a load equal to or greater than the predetermined value, the support member is damaged at the position of the fragile portion and is engaged. The engagement state between the portion and the first exterior component is released. As a result, with respect to the first exterior component, it is possible to prevent the damage from occurring or to make the damage mild. Therefore, it is possible to improve the repairability and reduce the repair cost.

However, conventionally, there are problems to be solved as described below.

That is, in the above-mentioned Patent Document 1, the damage to the first exterior component at the time of a frontal collision of the vehicle can be suppressed by the first and second exterior components (more accurately, the outer plate portions thereof). The condition is that they are arranged side by side in the vertical direction, and if this condition is not met, the effect of preventing damage to the exterior parts cannot be obtained.
Specifically, in a vehicle such as an automobile, when two exterior components are provided side by side in the vehicle front-rear direction, a front collision or a rear collision of the vehicle causes one of the exterior components to front or Load input may occur from the rear. Similarly, when the two exterior components are arranged side by side in the vehicle width direction, a side collision of the vehicle may cause a load input to one of the exterior components. However, in Patent Document 1, in the case of load input in such a mode, the action of protecting the exterior component cannot be obtained. Therefore, it is desired to eliminate such a problem.

Further, in Patent Document 1, the engagement state of the engagement claw can be released at the time of a frontal collision of the vehicle. However, in order to ensure the release operation, the engagement claw and the engaged portion are It is necessary to make the engagement state considerably loose. This causes a problem that rattling occurs between the two exterior parts.

JP, 2008-49859, A

The present invention has been devised under the circumstances as described above, and two exterior parts are provided in an arrangement arranged side by side in the vehicle front-rear direction or the vehicle width direction. A vehicle in which damage to the exterior parts can be reduced and repairability can be improved when a load is input in the direction in which the exterior parts are lined up, and the exterior parts can be properly mounted during normal operation. The challenge is to provide a structure.

In order to solve the above problems, the present invention takes the following technical means.

The vehicle structure provided by the present invention is a resin first member that forms an outer surface portion of a vehicle under the condition that one of the vehicle front-rear direction and the vehicle width direction is the x direction and the other is the y direction. And a second outer plate portion, and the first and second outer plate portions are provided with first and second exterior parts provided so as to be adjacent to each other in the x direction. And a first and a second extending portion which are provided so as to extend inward of the vehicle in the y direction from the first and second outer plate portions and which face each other in the x direction, and the first and second extending portions. An engaging claw provided on the extending portion of the vehicle and protruding toward the second extending portion side, and an outside of the vehicle in the y direction provided on the second extending portion and more than the engaging claw. an engaging portion which is positioned in a square the side engaged with the engagement claws, of the second extending portion, provided in the region of the vehicle outer side in the y direction than the engaging portion, and wherein A corner portion is formed at the boundary with the engaging portion, and a gap is formed between the first extension portion and the width of the gap in the x direction increases toward the vehicle outer side in the y direction. An inclined surface that is inclined so that the first exterior component has a load input in the x direction that is greater than or equal to a predetermined value, and the first extension portion is pressed against the engagement portion. Sometimes, the first extension portion rotates about the corner portion as a fulcrum so as to disengage the engaging claw from the engaging portion and abuts on the inclined surface, and the inclined surface is the first exterior member. It is characterized in that it can be guided so that the parts are deflected to the outside of the vehicle in the y direction .
Here, the vehicle outer side in the y direction means the vehicle width direction outer side when the y direction is the vehicle width direction. Further, when the y direction is the vehicle front-rear direction, it is on the vehicle front side if the first and second exterior components are located on the vehicle front portion, and is on the vehicle rear side if it is located on the vehicle rear portion. The vehicle inward side in the y direction is the direction opposite to the direction described above.

According to such a configuration, as will be understood from the embodiment described later, for example, the first and second exterior components are provided so that the first and second outer plate portions are adjacent to each other in the vehicle front-rear direction. In this case, when the front collision of the vehicle occurs, it is possible to prevent the first exterior component from strongly pressing the second exterior component and damaging the second exterior component. The same action as this can be obtained even in the case of a rear-end collision of the vehicle, and in the state where the first and second outer plate portions are arranged side by side in the vehicle width direction, a side collision of the vehicle It is possible to obtain even when occurs. Therefore, the vehicle structure according to the present invention is excellent in versatility, and although various types of exterior components are used as the first and second exterior components, the exterior components are damaged due to the collision of the vehicle. This can be appropriately suppressed. As a result, there are advantages that the repairability is improved and the repair cost is reduced.
Further, according to the present invention, the operation of releasing the engagement state between the engagement claw and the engagement portion at the time of a vehicle collision is performed more smoothly and reliably than in Patent Document 1. Therefore, in the normal state, the engaging claw and the engaging portion can be firmly engaged with each other, and the first and second exterior parts can be prevented from rattling.

Other features and advantages of the present invention will become more apparent from the following description of the embodiments of the invention with reference to the accompanying drawings.

1 is an external perspective view showing an example of a vehicle to which a vehicle structure according to the present invention is applied. (A) is a plane cross-sectional view of a main part IIa-IIa of FIG. 1, and (b) and (c) are main parts showing an example of an operation when a load is input to the structural part shown in (a). It is a plane sectional view.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

The vehicle V shown in FIG. 1 includes a bumper 1 (front bumper) and a fender panel 2 (front fender panel) both made of resin.
The bumper 1 and the fender panel 2 correspond to specific examples of the first and second exterior parts referred to in the present invention, respectively.
In the present embodiment, the vehicle front-rear direction corresponds to the x direction in the present invention, and the vehicle width direction corresponds to the y direction in the present invention.

As shown in FIG. 2A, the bumper 1 and the fender panel 2 have first and second outer plate portions 10 and 20 (bumper body portion, fender panel body portion) that form an outer surface portion of the vehicle V. doing. In the bumper 1 and the fender panel 2, on the side surface portion of the vehicle V, the front end portion 20a of the second outer plate portion 20 is adjacent to the vehicle rear side of the longitudinal end portion 10a of the first outer plate portion 10. It is attached to the vehicle V in the state of being positioned as described above.

The first outer plate portion 10 of the bumper 1 is continuously provided with a first extension portion 11 extending inward in the vehicle width direction from the vicinity of the end portion 10a, and the tip of the first extension portion 11 is provided. Engagement claws 13 are formed on the portion so as to project rearward of the vehicle. On the other hand, the second outer plate portion 20 of the fender panel 2 has a region that extends inward in the vehicle width direction from the front end 20a and that has a region facing the first extending portion 11 in the vehicle front-rear direction. The extended portion 21 of is continuously provided.

The second extending portion 21 of the fender panel 2 includes a recess 24 into which the engaging claw 13 enters, an engaging portion 23 provided adjacent to the recess 24 and engaged with the engaging claw 13, Also, the inclined surface 25 is formed over substantially the entire width region of the region Sa on the vehicle width direction outer side of the engagement portion 23. The inclined surface 25 is also formed at a location corresponding to the end surface of the end portion 20a of the second outer plate portion 20. A portion 29 of the second extending portion 21 that is located on the vehicle width direction inner side or the vehicle front side of the recess 24 is used to fix the fender panel 2 to another vehicle body component.

The engaging portion 23 is located on the outer side in the vehicle width direction with respect to the engaging pawl 13, and the engaging pawl 13 engages with a side surface portion of the engaging portion 23. The tip of the engaging portion 23 is in contact with the first extending portion 11 so as to face it. The inclined surface 25 is inclined so as to be positioned on the vehicle rear side toward the vehicle width direction outer side, and between the inclined surface 25 and the portion near the base end portion of the first extending portion 11, A gap 3 is formed. The gap 3 displaces the first extending portion 11 toward the vehicle rear side by an appropriate distance at the time of a frontal collision of the vehicle V described later to release the engagement between the engaging claw 13 and the engaging portion 23. To help. A gap 30 is also formed between the end surface 10b of the first outer plate portion 10 and the inclined surface 25. This gap 30 is provided between the first and second outer plate portions 10 and 20. Since it is a so-called parting gap formed in the above, unlike the gap 3, it is preferably made as small as possible (however, the gap 30 is shown to be slightly larger in the drawing).

The first and second extending portions 11 and 21 are, for example, configured to extend uniformly in the vertical height direction, and the vertical lengths of the first and second extending portions 11 and 21 are the same as those of the first and second outer plate portions 10 and 10. The lengths of the end portions 10a, 20a of 20 in the vertical direction are substantially the same. However, the present invention is not limited to this, and, for example, the first and second extending portions 11 and 21 may have shorter vertical lengths, and the first and second outer plate portions 10 and 20 in the vertical height direction. It is also possible to have a configuration in which they are dispersed and provided in a plurality of locations.

Next, the operation of the vehicle structure described above will be described.

First, when the vehicle V has a front collision (light collision), and as shown in FIG. 2B, when a load F of a predetermined amount or more is input to the bumper 1 from the vehicle front side, the first extension of the bumper 1 is performed. While a part of the portion 11 is pressed against the engaging portion 23, a portion of the first extending portion 11 on the vehicle width direction outer side of the engaging portion 23 is displaced toward the vehicle rear side. Such a displacement causes the first extending portion 11 to rotate about the corner portion 23a of the engaging portion 23 as a fulcrum. By this rotation operation, the engagement claw 13 is displaced toward the vehicle front side relative to the engagement portion 23, and the engagement state with the engagement portion 23 is released. Since such engagement releasing operation displaces the engaging claws 13 according to the lever principle or a principle similar thereto, it can be smoothly and surely performed.

On the other hand, since the end surface 10b of the bumper 1 is pressed against the inclined surface 25, the end portion 10a of the bumper 1 is deflected outward in the vehicle width direction by the guide action of the inclined surface 25, and is inclined outward of the vehicle as indicated by an arrow Na. Displaces to the rear. As a result, as shown in FIG. 2C, the end portion 10a of the bumper 1 projects outward in the vehicle width direction from the second outer plate portion 20 of the fender panel 2, so that the fender panel 2 can be removed from the vehicle. Pushing backwards with great force is avoided. On the other hand, when the amount of deformation of the first extension portion 11 increases, the first extension portion 11 is also pressed against the inclined surface 25, but this portion is also guided to the outside of the vehicle by the guide action of the inclined surface 25. Displaced diagonally backward. Therefore, it is also possible to prevent the first extension portion 11 from pressing the fender panel 2 toward the vehicle rear side with a large force.

By such a series of actions, damage to the fender panel 2 can be prevented. As a result, the repairability is improved, and the repair cost of the vehicle V can be reduced.

The present invention is not limited to the contents of the above-mentioned embodiment. The specific configuration of each part of the vehicle structure according to the present invention can be modified in various ways within the scope intended by the present invention.

The exterior components (first and second exterior components) referred to in the present invention may be those provided with a resin outer plate portion forming an outer surface portion of the vehicle, and include, for example, the above-described front bumper and fender. In addition to the panel, a bumper or fender panel for the rear, a panel other than the fender panel, a head lamp, a grill, a front or rear turn lamp, a combination lamp, and the like are also included in the exterior component of the present invention. As will be understood from these specific examples, the exterior component is not limited to the one disposed at the front portion of the vehicle, and may be the one disposed at the rear portion of the vehicle and further at the side portion of the vehicle. Good.
