Installation structure and method for vehicle signal lamp

Abstract

The invention provides an installation structure and method for a vehicle signal lamp. By means of the coordination of a lamp-holder installation portion arranged on a lamp-holder body and a lamp-holder installation hole and the coordination of a hand-shank installation portion arranged on the lamp-holder body and a hand shank, the plug-pull type installation of a lamp holder is realized. The lamp-holder installation portion is provided with position-limiting bosses, elastic installation clamping buckles, clamping-stopping bosses, reversed-thorn type elastic components and grooves, wherein theelastic installation clamping buckles are symmetrically arranged on the side wall of the lamp-holder body in an embedded manner in the axial direction, the clamping-stopping bosses are arranged on the outer side surfaces of the elastic installation clamping buckles, the reversed-thorn type elastic components are arranged on the inner side surfaces of the elastic installation clamping buckles, thegrooves are matched with the reversed-thorn type elastic components, and one ends of the elastic installation clamping buckles are higher than the end surface of the lamp-holder body and are hangingly arranged in tooth shapes; the lamp-holder installation hole forms an installation-hole inlet end surface and is provided with position-limiting clamping-stopping slots, positioning convex ribs, hoop-type convex ribs and open slots, wherein the positioning convex ribs are distributed on the inner side wall of the installation hole in the radial direction; and the hand-shank installation portion is provided with through-holes, a hand-shank base seat is composed of disc components and shank-shaped components which are arranged on the disc components, and the end portions of the shank-shaped components are provided with elastic clamping buckles.

Description

technical field [0001] The invention belongs to the field of vehicle lamps, and in particular relates to a vehicle signal lamp installation structure and an installation method thereof. Background technique [0002] The lamp holder is generally composed of a lamp holder body and a number of contact pieces. The tail of the contact piece can be connected to the outside with wires or PIN needles, etc., and a sealing ring can also be provided according to the sealing requirements. When in use, a light bulb used as a light source is put into the lamp holder, and the electrodes on the base of the bulb are in contact with the contact pieces provided in the lamp holder to realize electrical connection. Then, the lamp holder is installed on the lamp shell or the reflector to realize the installation of the bulb relative to the lamp. [0003] Plug-in lamp holders are generally installed with the lamp body or reflector through elastic mounting buckles. Ordinary elastic mounting buckle...

AI Technical Summary

Problems solved by technology

[0003] Plug-in lamp holders are generally installed with the lamp body or reflector through elastic mounting buckles. Ordinary elastic mounting buckles are generally connected on one side, and the root is prone to cracks or even broken risks. The reliability is not high, and there are potential safety hazards

In addition, it is difficult to set the pull-out force between the lamp holder and the lamp housing or reflector. Although it can be realized by increasing or decreasing the wall thickness of the elastic mounting buckle, if the pull-out force is set too small, it is easy to cause the lamp The seat falls off, and it is not easy to disassemble if the pull-out force is set too high
