Description

  The present invention relates to a vehicle component mounting structure for mounting a panel-like component such as a scuff panel on a component mounting surface of a vehicle body, such as a rocker panel.

  As a conventional mounting structure for vehicle parts, for example, there is a structure disclosed in Patent Document 1. In this conventional structure, when a harness clamp is attached to the rocker panel, a locking claw having a pair of locking protrusions symmetrical to the insertion direction is provided on the lower surface of the harness base of the harness clamp, Each locking projection of the locking claw is locked to both edge portions of mounting holes formed on the mounting surface of the rocker panel.

Japanese Patent No. 3264583

By the way, in the mounting structure of the conventional vehicle parts, the mounting surface of the rocker panel and the insertion direction to the mounting hole of the locking claw of the harness clamp are orthogonal,
Even when the pair of locking projections of the locking claw are formed so as to be symmetrical with respect to the insertion direction, the locking claw can be locked in the mounting hole without any trouble.

On the other hand, the mounting surface of the mounting portion of the vehicle body is inclined with respect to the horizontal plane, and the insertion direction of the locking claw of the vehicle part is the vertical direction. May be diagonal. In such a case, depending on the shape of the locking claw, there is a concern that it is difficult to lock the locking claw in the mounting hole, or that the locking strength is insufficient and the removal is difficult.

  The present invention has been made in view of the above-described conventional situation. Even when the insertion direction of the locking claw is oblique to the mounting surface, the locking claw is easily and reliably engaged with the mounting hole with sufficient locking force. It is an object of the present invention to provide a vehicle component mounting structure that can be stopped and easily removed.

The present invention provides a vehicle component mounting structure in which a locking claw formed on a vehicle component is locked in a mounting hole formed on a component mounting surface of a vehicle body.
The component mounting surface is inclined with respect to the insertion direction of the locking claw,
The locking claw includes a low-side protrusion that is locked to a low-side edge that is located on a low-side of the inclined surface, and a high-side edge that is positioned on a high-side of the inclined surface. A high side protrusion and a low side protrusion, the front side inclined surface located on the front side in the insertion direction and the rear side inclined surface located on the rear side in the insertion direction. And has a Yamagata shape with
An angle of the rear inclined surface of the low-side protrusion with respect to the mounting surface is set to be smaller than an angle of the rear inclined surface of the high-side protrusion with respect to the mounting surface. Mounting structure.

  In the present invention, when the component mounting surface is inclined with respect to the insertion direction of the locking claw, the lower side protrusion of the locking claw that locks to the lower side edge of the mounting hole. The angle of the rear inclined surface with respect to the mounting surface is set to be smaller than the angle with respect to the mounting surface of the rear inclined surface of the high-side protrusion that is locked to the high-side edge of the mounting hole. Even when the mounting hole is low, the low side edge and high side edge of the mounting hole are locked to the low side projection and high side projection of the locking claw with approximately the same amount of lap. The locking claw can be locked in the mounting hole with force.

Further, when removing the vehicle part, the low-side protrusion is raised to the low side of the mounting hole by pulling up the part of the vehicle part where the low-side protrusion is provided in the direction opposite to the insertion direction. Since it comes off the edge, it is easy to remove the vehicle parts.

It is a front perspective view of the side panel of the motor vehicle provided with the attachment structure of the scuff panel which concerns on Example 1 of this invention. It is a front perspective view of the scuff panel. FIG. 3 is a cross-sectional view of the scuff panel (a cross-sectional view taken along line III-III in FIG. 2). FIG. 4 is a cross-sectional side view of the scuff panel mounting structure (a cross-sectional view taken along line IV-IV in FIG. 1). It is a perspective view of the latching claw of the attachment structure of the said scuff panel.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1-5 is a figure for demonstrating the attachment structure of the scuff panel which concerns on Example 1 of this invention.

In the figure, reference numeral 1 denotes a side panel constituting a vehicle body side portion. The side panel 1 has a front door opening 1a and a rear door opening 1b, and a front scuff panel is provided on each of the front part 2a and the rear part 2b of the rocker panel 2 constituting the lower side of the front door opening 1a and the rear door opening 1b. 3. A rear scuff panel 4 is attached according to the embodiment structure of the present invention. Since both the front and rear scuff panels 3 and 4 have the same mounting structure, the mounting structure of the front scuff panel 3 will be described below.

The rocker panel 2 is a cylindrical body formed by connecting a rocker outer panel 2c and a rocker inner panel 2d with flanges 2e 'and 2e', and a mounting surface 2e for mounting the front scuff panel 3 on the rocker outer panel 2c. Is formed. The attachment surface 2e is inclined with respect to the horizontal plane so that the outside in the vehicle width direction is lower, and an attachment hole 2f having a rectangular shape in plan view is formed in the middle.

The front scuff panel 3 has a length that covers substantially the entire length of the straight portion of the lower side of the front door opening 1a, and an outer portion 3a that covers the rocker outer panel 2c side of the rocker panel 2 and the rocker inner panel 2d side. And an inner part 3b covering the inner part. The inner portion 3b is generally arc-shaped, while the outer portion 3a is inclined so as to be substantially parallel to the mounting surface 2e of the rocker outer panel 2a.

A locking claw 5 is integrally formed on the lower surface of the outer portion 3a of the front scuff panel 3 so as to protrude vertically downward, and the locking claw 5 is inserted vertically downward with respect to the mounting hole 2f. . Accordingly, the mounting surface 2e of the rocker outer panel 2c is inclined with respect to the insertion direction.

The locking claw 5 is formed at a lower end portion of the leg portion 5c integrally formed on the lower surface of the outer portion 3a and at the lower end portion of the leg portion 5c, and the mounting hole 2f has a lower side in the inclination direction of the mounting surface 2e. A low-side protrusion 5a that engages with a low-side edge 2f 'that is positioned at a high-side, and a high-side protrusion 5b that engages with a high-side edge 2f' 'that is positioned at a high side in the inclination direction. . The low-side protrusion 5a has a front inclined surface 5a 'positioned on the front side in the insertion direction of the locking claw 5 and a rear inclined surface 5a' 'positioned on the rear side in the insertion direction, with a being the apex. Yamagata. Similarly, the high-side protrusion 5b has a front inclined surface 5b 'positioned on the front side in the insertion direction and a rear inclined surface 5b' 'positioned on the rear side in the insertion direction, and has a mountain shape with a as the apex. Yes.

  Here, the angle θ1 of the rear side inclined surface 5a ″ of the low-side protrusion 5a with respect to the mounting surface 2e is set to be equal to the mounting surface 2e of the rear inclined surface 5b ″ of the high-side protrusion 5b. It is set smaller than the angle θ2.

In addition, an angle θ1 ′ of the front inclined surface 5a ′ of the low-side protrusion 5a with respect to the attachment surface 2e is an angle θ2 ′ of the front inclined surface 5a ′ of the high-side protrusion 5b with respect to the attachment surface 2e. It is set smaller.

Furthermore, the lower side edge 2f 'of the mounting hole 2f is locked in the vicinity of the center in the vertical direction of the rear inclined surface 5a "of the lower side protrusion 5a. The height side edge 2f "is locked to the vicinity of the center in the vertical direction of the rear inclined surface 5b" of the height side protrusion 5b. Therefore, the amount of lap d1 between the low-side protrusion 5a and the low-side edge 2f 'is substantially equal to the amount of lap d2 between the high-side protrusion 5b and the high-side edge 2f' '. ing.

In this embodiment, when the front scuff panel 3 is mounted on the rocker panel 2, the inner portion 3b of the front scuff panel 3 is covered on the rocker inner panel 2d side, and the outer portion 3a is covered on the rocker outer panel 2c side. Then, the locking claw 5 is pushed substantially vertically downward toward the mounting hole 2f. Then, the lower side projection 5a and the high side projection 5b of the locking claw 5 have front inclined surfaces 5a 'and 5b' at the lower side edge 2f 'and the higher side edge 2f' 'of the mounting hole 2f. While being pressed and elastically deformed inward, the apex a passes through the low side and high side edges 2f ′ and 2f ″, and the low side and high side edges 2f ′ and 2f ″ Locking is performed with wrap amounts d1 and d2.

In the present invention, when the mounting surface 2e is inclined with respect to the insertion direction of the locking claw 5, the locking claw 5 is locked to the lower side edge 2f 'of the mounting hole 2f. The rear inclined surface 5b of the high-side protrusion 5b that locks the angle θ1 of the rear-side inclined surface 5a ″ of the high-side protrusion 5a with respect to the mounting surface 2e to the high-side edge 2f ″ of the mounting hole 2f. Since the angle ′ is smaller than the angle θ2 with respect to the mounting surface 2e, even when the mounting surface 2e is inclined, the low side edge 2f ′ and the high side edge 2f ″ of the mounting hole 2f The locking claw 5 can be locked to the mounting hole 2f with a sufficient locking force because it is locked to the low-side protruding portion 5a and the high-side protruding portion 5b with substantially equal wrap amounts d1 and d2. it can.

Further, an angle θ1 ′ of the front inclined surface 5a ′ of the low-side protrusion 5a with respect to the mounting surface 2c is defined as an angle θ2 ′ of the front inclined surface 5a ′ of the high-side protruding portion 5b with respect to the mounting surface 2c. Since it is set smaller, even when the mounting surface 2e is inclined, when the locking claw 5 is inserted into the mounting hole 2f, the lower side edge 2f ′ and the higher side edge 2f ″ of the mounting hole 2f. Since the lower side protrusion 5a of the locking claw 5 and the front inclined surfaces 5a 'and 5b' of the high position protrusion 5b start to contact substantially simultaneously, the locking claw 5 can be smoothly inserted into the mounting hole 2f. , Workability can be improved.

Incidentally, as in the conventional structure, when a locking claw that is formed so that the locking projection is symmetrical is inserted into the mounting hole on the inclined mounting surface, either locking projection is attached first. There is a concern that the locking claw tends to fall because it abuts against the edge of the hole, and the locking claw cannot be smoothly inserted into the mounting hole, resulting in a decrease in workability.

Furthermore, when the front scuff panel 3 is removed from the rocker panel 2, the front end portion 5d of the front scuff panel 3 on the side where the low-side protrusion 5a is provided is pulled up in the direction opposite to the insertion direction. As a result, the low side projection 5a is disengaged from the low side edge 2f 'of the attachment hole 2f, so that the front scuff panel 3 can be easily removed.

In the above-described embodiment, the case where the front and rear scuff panels 3 and 4 are attached to the rocker panel 2 has been described. However, the scope of application of the present invention is not limited to the above-described embodiment, and forms an inclined surface of the vehicle body. The present invention can be applied to any case where the locking claws of the panel-like component are inserted obliquely into the mounting holes formed on the component mounting surface.
