Description

  The present invention relates to a bumper device for a vehicle provided with a lamp.

Some bumper devices for vehicles are formed by dividing a bumper face forming a design into an upper part and a lower part.
In this bumper face, an upper bumper that forms an upper part and a lower bumper that forms a lower part are coupled together by a concave and convex engaging portion. The concave / convex engaging portion is fitted with the lower bumper's locking claws in the front / rear direction of the vehicle body in the locking hole of the upper bumper, so that it can be positioned and the number of parts and assembly man-hours can be reduced (for example, Patent Document 1).

  Moreover, it fits by moving the front part of the 2nd bumper member which makes a lower part to the front part of the 1st bumper member which makes an upper part, and moves each side part connected to a front part to an up-down direction. The workability is improved (see, for example, Patent Document 2).

Further, there is a type in which a bumper face and a lamp are attached to a support member of a vehicle body. When this support member is pushed in at the time of a collision with the bumper face, the engaging claw is detached from the lamp body, so that a collision load is not transmitted from the support member to the lamp body (for example, Patent Document 3). reference).
In addition, a shock absorber is disposed between the vehicle body and the bumper face (see, for example, Patent Document 4).

On the other hand, there is a lamp that can be attached to the bumper face.
The lamp body is attached to the vehicle body, and the socket protection rib is provided so as not to come into contact with the vehicle body when the lamp body is moved in the lateral direction when removed, so that the lamp body can be protected (for example, Patent Document 5). reference).

  However, in the prior art (Patent Documents 1 and 2), the lamp body is not attached, but the lamp body may have to be attached. If a lamp body such as a fog lamp is attached to the bumper face, the lamp body is not It can be pushed and destroyed.

In Patent Document 3, the lamp is attached to the support member of the vehicle body, but it cannot be used when the lamp is attached to the bumper face due to conditions such as design or legal restrictions.
If the lamp body is attached to the bumper face, the lamp body is pushed together with the bumper face at the time of a collision, so that it is considered that the lamp body hits and is destroyed, and a separate member for protection is required.

In Patent Document 4, if a lamp body is attached to the bumper face, a dedicated shock absorbing material is required so that the lamp body is not pushed and destroyed at the time of collision. Providing a dedicated shock-absorbing material, such as polystyrene foam, complicates the production.
That is, a resin molding die for producing an impact cushioning material made of foamed polystyrene is required, the number of parts increases, management of the impact cushioning material made of foamed polystyrene occurs, and a process of assembling the impact cushioning material made of foamed polystyrene It is necessary to provide. That is, manufacturing is complicated.

  In Patent Document 5, the lamp body is attached to the vehicle body. However, if the lamp body provided with the socket protection rib is attached to the bumper face, the lateral direction (outward in the vehicle width direction) is caused by the collision load input to the bumper face. ) Can be protected by the socket protection rib, but there is no protection rib to protect when pushed in the longitudinal direction of the vehicle body, and it is necessary to attach a lamp corresponding to the load in the longitudinal direction of the vehicle body.

  Next, the operation of the bumper device 12 of the vehicle 11 will be described. A mechanism for protecting the lamp body 31 of the bumper device 12 will be described with reference to FIGS. 9A is a cross-sectional view corresponding to FIG. 3, and FIG. 9B is a detailed view of a portion b in FIG. 9A.

  In the bumper device (rear bumper device) 12, when the vehicle 11 collides rearward, the bumper face 27 moves up and down, so that the remaining bumper face upper 35 and the lamp body 31 are difficult to transmit the compressive load due to the rear collision, and the lamp body 31. Can be protected.

  Specifically, when an object 104 (for example, another vehicle or an obstacle) collides with the bumper face lower 36 shown in FIGS. 3 and 9A and a collision load is applied as indicated by an arrow b1, the bumper face is reduced. 27 is pushed from the position indicated by the two-dot chain line toward the vehicle body 14 as indicated by the arrow b2 as indicated by the solid line.

  That is, since a plurality of locations of the bumper face lower 36 are joined to the bumper face upper 35 (upper edge 86, lower edge 87), the bumper face upper 35 also tries to move, and the bumper lower separation mechanism 45 is almost centered. A force (moment) is generated obliquely forward and upward (in the direction of arrow a5) (see also FIG. 4). This force makes it easier for the locking claw 66 to come off.

  As shown in FIG. 9A, when the absorber portion 41 of the bumper face upper 35 to be pressed comes into contact with the vehicle body 14 (the skeleton member 28), the bumper face upper 35 moves toward the vehicle body 14 (in the direction of the arrow b2). Be regulated.

Even after the movement of the bumper face upper 35 is restricted, the bumper face lower 36 continues to be pushed toward the vehicle body 14 as shown by the arrow b2, and as shown in FIG. The engaging hole 61 of the engaging portion 62 is detached from the portion 65.
At that time, the engaging claw 66 is elastically deformed and bent upwards of the vehicle 11, so that the engaging portion 62 is easily detached.

  Since the engaging portion 62 is detached from the locking claw 66 and the engaging portion 62 is in a free state, the bumper face upper 35 does not follow the bumper face lower 36 any more, and the lamp body 31 is A distance Sa (Sa = S−As) is obtained by subtracting the compressed stroke amount As (not shown) of the absorber 41 from the distance S (FIG. 3) between the vehicle body 14 (the frame member 28). The lamp body 31 does not collide with the vehicle body 14 (the skeleton member 28).

  As shown in FIG. 9, when the absorber 41 abuts against the vehicle body 14 (the skeleton member 28) in the case of a rear collision, the absorber main body 46 is compressed and deformed, and the vertical wall 51 is bent and extended. Therefore, the collision load can be absorbed, and the function of the lamp body 31 can be secured.

  In the bumper lower separation mechanism 45, the absorber main body 46 and the locking claw 66 are integrally molded at the same time on the bumper face upper 35, and the engaging portion 62 is molded at the same time on the bumper face lower 36. There is an advantage that the mold does not increase, the number of parts does not increase, and the absorber main body 46, the locking claw 66, and the engaging portion 62 need not be individually managed or assembled. That is, manufacturing is simplified.

  Although the vehicle bumper device of the present invention is employed in the rear end portion 33 of the vehicle 11 in the embodiment, it may be employed in the front end portion of the vehicle 11 as a front bumper device. The front bumper device exhibits the same effect when a frontal collision occurs. Naturally, change the design of the bumper face.

  The bumper device 12 of the vehicle 11 of the present invention is suitable for an automobile.
