Description

The present invention relates to a vehicle structure that is less likely to cause damage to exterior parts due to a vehicle collision (damageability: improved damageability) and improves repairability.
The vehicle collision referred to in this specification is a light collision in which a vehicle collides relatively weakly with a pole, an oncoming vehicle, or the like at a traveling speed in a low speed range such as slow driving unless otherwise specified.

As an example of the vehicle structure, there is a vehicle structure described in Patent Document 1.
In the vehicle structure described in this document, for example, two exterior parts such as a lamp and a bumper are provided adjacent to each other in the vertical direction of the vehicle, and these are engaged via an engaging portion. However, when the vehicle collides and a load input to the bumper exceeds a predetermined value, the engagement state using the engagement portion is released. Thus, although the bumper is damaged due to the load input, the lamp is prevented from being damaged and the repairability can be improved.

  However, in the past, there was room for improvement as described below.

That is, in Patent Document 1 described above, exterior parts that can prevent damage during a vehicle collision are limited to exterior parts such as bumpers and lamps that are provided side by side in the vertical direction of the vehicle. On the other hand, many automobiles include a hood that covers an engine room at the front of the vehicle, and front fender panels are arranged on both the left and right sides of the hood in the vehicle width direction. In many cases, a hood (trunk lid) for covering the trunk room is provided at the rear of the vehicle, and rear fender panels are disposed on both left and right sides of the hood in the vehicle width direction.
In a vehicle equipped with a hood and left and right fender panels as described above, a side collision occurs, and when the load is input to one of the left and right fender panels, the hood is damaged as a result of the fender panel pressing the hood strongly. Or the load is transmitted to the other fender panel located on the opposite side of the fender panel via the hood, and the other fender panel may be damaged. On the other hand, in patent document 1, such a phenomenon cannot be prevented appropriately.

JP 2008-49859 A

  The present invention has been conceived under the circumstances as described above, and is a member located on the opposite side of the hood from the damage of the hood caused by a side collision of the vehicle or the side collision side of the vehicle. It is an object of the present invention to provide a vehicle structure that can appropriately prevent or suppress damage to the vehicle and improve repairability.

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

The vehicle structure provided by the present invention includes a hood provided at the front or rear of the vehicle, and is positioned on the outer side in the vehicle width direction of the hood, and an end is provided adjacent to the hood. A side collision hood raising means for raising the hood to a position higher than the end of the exterior member at the time of a side collision of the vehicle. It is characterized by being.

According to such a configuration, the following effects can be obtained.
That is, even if a side collision of the vehicle occurs and the exterior member is deformed or displaced inward in the vehicle width direction, the hood is disposed higher than the end of the exterior member by the operation of the side hood raising means. Therefore, it is avoided or suppressed that the exterior member collides with the hood. Accordingly, the hood is damaged due to deformation or displacement of the exterior member, or the collision load input to the exterior member is transmitted to the other exterior member located on the opposite side of the exterior member via the hood. It can prevent or suppress that this exterior member is damaged appropriately. As a result, repairability can be improved and repair costs can be reduced. Since a hood (engine hood or hood as a trunk lid) is provided in many automobiles, the present invention that can prevent damage to a hood or a member (such as a fender panel) adjacent to the hood is applied. Wide range is preferred.

  In the present invention, preferably, the side hood raising means is capable of maintaining an elastic member disposed below a hood hinge bracket that rotatably supports the hood and a state in which the elastic member is elastically deformed. And at least a portion of the elastic member and a regulating member provided so as to be positioned outward in the vehicle width direction relative to the hood hinge bracket, and the regulating member at the time of a side collision of the vehicle The hood can be lifted together with the hood hinge bracket using the elastic force of the elastic member by being displaced inward in the vehicle width direction by a load input from the outside in the vehicle width direction. Has been.

  According to such a configuration, it is possible to appropriately obtain the operation intended by the present invention while simplifying the configuration of the side collision hood raising means and making it relatively inexpensive.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present 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 IIa-IIa principal part sectional drawing of FIG. 1, (b) is principal part sectional drawing which shows the example of an effect | action when a load input is produced in the structure part shown to (a). It is a principal part cross-sectional perspective view of the part shown to Fig.2 (a).

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

  A vehicle V shown in FIG. 1 includes a hood 1 (engine hood) that covers an engine room 90 provided at a front portion, and a pair of fender panels 2 (front fenders) that are located on the left and right outer sides of the hood 1 in the vehicle width direction. Panel).

As shown in FIG. 2 (a), the hood 1 is configured by joining a hood outer panel 1a and a hood inner panel 1b. Both the panels 1a and 1b are made of, for example, a resin, such as a metal reinforcement. It is reinforced appropriately using. The hood 1 is rotatably supported via a hood hinge bracket 4 mounted on the apron member 3. Each fender panel 2 is made of, for example, resin, like the hood 1, and is fixed to the side of the vehicle so that its end 20 (upper end) is adjacent to the end 10 in the vehicle width direction of the hood 1. Yes.

The vehicle structure of the present embodiment is provided with a side hood raising structure portion A that raises the hood 1 at the time of a side collision of the vehicle V (see also FIG. 3).
The side hood raising structure portion A corresponds to an example of the “side collision hood raising means” in the present invention, and is connected to the base portion 40 of the hood hinge bracket 4 and extends below the base portion 40. A shaft-shaped or bar-shaped support member 5, a spring 6, and a regulating member 7 are provided. The spring 6 corresponds to an example of an elastic member in the present invention, and is, for example, a compression coil spring. The support member 5 includes a shaft-shaped portion 50 and a base 51 that is connected to the lower portion of the shaft-shaped portion 50 and has a larger diameter than the shaft-shaped portion 50. The spring 6 is externally fitted to the shaft-like portion 50 of the support member 5 and is interposed at a position between the base portion 40 of the hood hinge bracket 4 and the regulating member 7 while being compressed in the vertical direction. Has been.

  The restricting member 7 is set in a substantially horizontal posture extending in the vehicle width direction by being inserted through a pair of holes 30 provided in the apron member 3 and can be displaced in the vehicle width direction. The restricting member 7 includes a protrusion 70 protruding outward in the vehicle width direction from the apron member 3, a load receiving portion 71 formed by bending the tip of the protrusion 70 in a bent shape, and the support member 5. Is provided with an elongated hole 72 that is inserted in the vertical height direction. When the vehicle V collides sideways and, as shown in FIG. 2 (b), a load F having a magnitude larger than a predetermined value in a substantially horizontal direction is input to the load receiving portion 71 via the fender panel 2, the regulating member 7 Slide inward in the width direction. As shown well in FIG. 3, the hole 72 includes a long hole 72 a through which the shaft-like portion 50 of the support member 5 is inserted, and a large diameter hole 72 b having a diameter larger than the width of the long hole 72 a. Are connected.

  In the normal state of FIGS. 2A and 3, the base 51 of the support member 5 is positioned on the lower side of the restricting member 7 and engages with the edge of the long hole portion 72 a, and the support member 5 is lifted. It is blocked. On the other hand, when there is an input to the load receiving portion 71 and the regulating member 7 slides inward in the vehicle width direction as shown in FIG. 2B, a large-diameter hole portion is formed at the position of the base portion 51 of the support member 5. 72b shifts. Then, the base 51 enters the large-diameter hole 72b and the support member 5 is allowed to rise, and the hood hinge bracket 4 and the hood 1 are raised by the elastic force of the spring 6. The rising height of the hood 1 is a height at which the end portion 10 of the hood 1 is higher than the end portion 20 of the fender panel 2, and the fender panel 2 and the hood are displaced inward in the vehicle width direction. It is a height at which interference with 1 can be avoided.

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

  First, in the normal state shown in FIG. 2A, the hood hinge bracket 4 can be appropriately fixed on the apron member 3 to stabilize the attachment state of the hood 1.

  Next, a side collision of the vehicle V occurs, and as shown in FIG. 2 (b), when there is an input of the load F caused by the side collision, as described above, the regulating member 7 is moved inward in the vehicle width direction. As a result of sliding, the engaged state between the support member 5 and the regulating member 7 is released, and the hood hinge bracket 4 and the hood 1 are raised by the elastic force of the spring 6. As a result, interference between the hood 1 and the fender panel 2 is avoided or the amount of interference is reduced. In this embodiment, since the hood hinge bracket 4 that supports the hood 1 is raised, a wide area of the hood 1 can be accurately raised.

For this reason, the hood 1 is appropriately prevented or suppressed from being strongly pressed and damaged by the fender panel 2. Unlike the present embodiment, if the load F is transmitted from one fender panel 2 to the hood 1, the load F is also transmitted to the other fender panel 2 located on the opposite side of the vehicle V. The fender panel 2 may be damaged. On the other hand, according to the present embodiment, such a concern can be appropriately eliminated. Therefore, repairability is good and repair costs can be reduced. Moreover, if the side collision hood raising structure part A is a light collision, it is hard to break easily, and there is a high possibility that it can be reused.

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

In the above-described embodiment, the hood raising structure portion at the time of side collision is configured to raise the hood hinge bracket using the spring force of the spring, but instead of or in addition to this, the hood hinge bracket You may make it raise, supporting other parts.
In the present invention, it is preferable that the entire area of the portion adjacent to the fender panel is raised to a position higher than the end of the fender panel so that no interference between the hood and the fender panel occurs at the time of a side collision of the vehicle. However, the present invention is not limited to this. For example, based on the fact that a part of the hood does not rise to a position higher than the fender panel, even if this hood is somewhat damaged, the collision load input to one fender panel will be If it is possible to prevent or suppress the transmission to the fender panel and prevent or suppress the breakage of the other fender panel, the repairability is improved as compared with the conventional one. Therefore, such a configuration is also within the technical scope of the present invention. Be included. In the present invention, the fender panel and the hood need not be set so as not to interfere at all at the time of a side collision of the vehicle, and a part of these may interfere with each other.

  As the hood raising means at the time of a side collision, for example, it is possible to adopt a configuration in which the hood is raised using an actuator such as an air cylinder. Moreover, it can also be set as the structure which raises a hood using the inflation gas generated by the inflator or the airbag itself like an airbag.

When the actuator method or the airbag method is adopted, a configuration in which a side collision detection sensor (acceleration sensor) for detecting a side collision of the vehicle can be used. In such a case, different operation control can be performed according to the detection value of the side collision detection sensor (the magnitude of the impact of the vehicle collision).
That is, when the detected value of the side collision detection sensor is a light collision with a predetermined value or less, the hood is raised to prevent damage to the hood. On the other hand, when the detected value is a vehicle collision exceeding a predetermined value, the hood is not raised. Thus, the hood is deformed at the time of a vehicle collision with a large impact, and this hood can be used as a shock absorbing member.

  As described above, the hood in the present invention is a concept including a trunk lid in addition to the engine hood. The exterior member referred to in the present invention is not limited to a fender panel.
