Description

  The present invention relates to a component mounting structure configured to lock a locking hole formed at a corresponding position of a mounting component with respect to a locking claw portion formed in a vehicle body. Preferably, the present invention is applied to a bumper bracket structure in which a bumper side part is attached to a lower part of a fender via a guide bracket.

In a vehicle such as an automobile, various technologies are employed as a component mounting structure for mounting various components to a vehicle body. In particular, the bumper is detachably attached to the vehicle body, and if the vehicle body is damaged due to minor collisions or contact accidents in the front-rear direction, the damage can be minimized by replacing only the bumper. it can. Therefore, various techniques for attaching the bumper member to the vehicle body have been proposed. In recent years, the bumper skin member is often arranged around the vehicle body from the front and back surfaces to the side surface, and the device for attaching the bumper side portion to the vehicle body has been devised. One example is disclosed in Patent Document 1 below.
Japanese Utility Model Publication No. 4-35953 (see FIG. 1)

  What was described in the said patent document 1 is demonstrated using FIG. In this automobile bumper mounting structure, a cross member 102 having a wide support surface with which the back surface of the bumper member 109 abuts is disposed at the end of the side member of the frame 101. The bumper member 109 is fixed in a state where the back surface thereof is in contact with the support surface 103 of the cross member 102, and the side portion 108a of the bumper skin 108 covering the bumper member 109 is attached to the side body 120 at the rear edge portion. It is fixed to.

  Thus, although the side part 108a of the bumper skin 108 can be securely attached to the side body 120 via the bracket 121, the attachment of the side part 108a of the bumper skin to the bracket 121 is performed by a number of screws 129. As a result, it is inferior to the labor-saving workability for screw hole alignment and screw screwing. Therefore, a configuration has been proposed in which the bumper side portion and the guide bracket are attached with almost one touch by combining the engagement of the engagement claw portion with the engagement hole and the clip as shown in FIG. .

  This will be briefly described. As shown in FIG. 4A, when the bumper side portion 34 is attached to the guide bracket 33 attached to the lower portion of the fender that has been turned around from the front and rear surfaces of the vehicle body, A locking hole 39 formed in a corresponding portion of the bumper side portion 34 is locked to a locking claw portion 37 formed in the vicinity, and the guide bracket 33 and the bumper side portion 34 are connected by a clip 41. It is configured to be joined.

  With such a configuration, the locking hole 39 of the bumper side portion 34 is locked to the locking claw portion 37 of the guide bracket 33 with one touch, and is a view as viewed from the arrow B in FIG. 4 (A). As shown in FIG. 4, the bumper side portion 34 is effectively prevented from coming off by the latching claw portion 37, and the clip 41 inserted in the latching hole in the joint surface between the guide bracket 33 and the bumper side portion 34 is surely secured. The withdrawal of both was prevented. In addition, the engagement and disengagement of these are performed with one touch, and the workability is remarkably improved.

  However, since the bumper side portion 34, which is the bumper skin, is made of synthetic resin or the like, by repeatedly attaching and detaching the guide bracket 33 to and from the engaging claw portion 37, as shown in FIG. This led to a situation where 39 edges were cut. Therefore, it is conceivable that the locking claw portion 37 on the side of the guide bracket 33 is weakened so that it can be easily removed. However, although the clip 41 is locked, the holding function of the bumper side portion 34 with respect to the guide bracket 33 is improved. There was a risk of damage.

  Therefore, the present invention solves such a problem of the conventional component mounting structure, makes it easy to remove the mounting component from the vehicle body, and has a conflicting function that can be securely held after mounting. An object is to provide a component mounting structure.

  Therefore, according to the present invention, in the component mounting structure configured to lock the locking hole formed at the corresponding position of the mounting component with respect to the locking claw portion formed in the vehicle body, the locking claw portion can be elastically deformed. In addition, a clip that joins the vehicle body and the mounting part is configured to restrain the locking claw portion.

In the component mounting structure configured to lock the formed locking hole, the locking claw portion is configured to be elastically deformable, and the locking claw portion is configured by a clip that joins the guide bracket and the bumper side portion. It is characterized by being configured to restrain Further, the present invention is characterized in that the locking claw portion is connected to a vehicle body or a guide bracket via a neck portion so as to be elastically deformable. In the present invention, the locking claw portion is formed on the upper surface of the guide bracket, the locking hole is formed on the upper surface of the bumper side portion, and end surfaces formed substantially orthogonal to the upper surface are joined to each other. The latching claw portion is constrained by the latching leg portion of the clip. Further, the present invention is characterized in that the guide bracket is detachably attached to a fender flange below the fender, and these are used as means for solving the problems.

  According to the present invention, in the component mounting structure configured to lock the locking hole formed at the corresponding position of the mounting component with respect to the locking claw formed on the vehicle body, the locking claw can be elastically deformed. In addition, the clip that joins the vehicle body and the mounting part is configured to restrain the locking claw part, so that the locking claw part can be elastically deformed in a highly rigid vehicle body and has low rigidity. Therefore, it is easy and smooth to remove the mounting part from the vehicle body, and damage to the periphery of the locking hole of the mounting part is prevented. In addition, the latching claw portion having low rigidity that can be elastically deformed is reliably restrained by a clip that joins the vehicle body and the mounting component, so that the deformation is effectively prevented, and the mounting component does not fall off unnecessarily.
