Problems solved by technology

The clearance fit prevents the structure from completely eliminating the looseness after installation. If the interference fit is used, the installation will not be in place.
In addition, this structure is not conducive to the disassembly of the switch cover or small lamps. It is necessary to use a tool to push

Embodiment Construction

[0013] exist figure 1 In the shown embodiment, the car switch cover or small lamp 1 is installed through the elastic clip arm 2 with barbs on the back and the mounting hole 3 on the car body. Elastic clip arms 2 are evenly and symmetrically distributed along the circumferential direction on the back of the switch cover or small lamp 1, one on the left and one on the left, and a positioning surface A is provided on the back of the switch cover or small lamp 1 to fit with the installation surface B of the mounting hole 3. In this structure, the working surface of the barb 4 at the front end of the elastic arm 2 on the back of the switch cover or the small lamp 1 is designed as a 30° slope surface 41, and the distance between the two symmetrical slope surfaces 41 must be greater than that of the installation hole 3 aperture. At the same time, anti-slip stripes 42 parallel to the installation surface are provided on the slope surface 41 of the barb.

Abstract

The invention discloses a mounting structure for a switch cover and a small lamp of an automobile. The switch cover or the small lamp of the automobile is arranged in a mounting hole on the automobile body through elastic clasp arms with inverted hooks at the back thereof. The elastic clasp arms are uniformly symmetrically distributed along the peripheral direction at the back of the switch cover or the small lamp. The back of the switch cover or the small lamp has a positioning surface which is adhered to a mounting surface of the mounting hole. The mounting structure for the switch cover and the small lamp of the automobile changes the conventional 90-degree hook-shaped structure to a 30-degree slope structure. Non-slip stripes are arranged on the slope surface, so that the clearance fit between the slope surface and the mounting surface is changed into the interference fit, and higher requirement on manufacturing accuracy between the mounting structure and the mounting hole is reduced. The thickness of the mounting hole surface is in a greater tolerance range, so the assembly requirement can be met as long as the bottom edge falls at any position of the slope. The manufacturing cost can be reduced, the positioning quality is higher after assembly, and the disassembly is simpler and more convenient simultaneously.

Description

technical field [0001] The invention relates to an automobile lighting appliance, in particular to an automobile switch cover and a mounting structure for a small lamp. Background technique [0002] The installation of existing automobile switch covers or small lamps on the vehicle body usually adopts a direct clamping installation method. See the specific structure figure 2 , which is to arrange several elastic clip arms 2 with barbs symmetrically on the back of the switch cover or small lamp 1. The length of the elastic clip arms 2 exceeds the depth of the installation hole 3, and the front end is a barb 4 protruding 90° outward. . The corresponding width of the mounting hole 3 on the vehicle body is greater than the maximum distance between the symmetrical elastic clamping arms 2 , but does not include the barb 4 protruding outward by 90°. When installing, directly insert the tip of the barb 4 into the installation hole 3. When the positioning surface A of the switch c...
