Description

TECHNICAL FIELD

The present invention relates to a car lamp, and more particularly, to a car lamp that obtains a better shock absorption effect by providing a shock absorption device. Background technique

Because cars often run on uneven roads, and there are various phenomena such as bumps, collisions, and braking, and the most vulnerable to damage during these phenomena is the bulb of the car's headlights. Therefore, the car lights need to be replaced frequently. Light bulbs, which will inevitably increase costs. In addition, due to the damage of the car's light bulb and the driver's failure to notice it in time, if it is not replaced in time, it will not only affect normal driving, but may also lead to traffic accidents and fines due to unqualified vehicle lights. As a result, serious losses are caused to the driver.

In order to solve the problem that the light bulb is easily damaged due to the above-mentioned vibration, the currently used car lights reduce the damage rate of the light bulb by providing a shock absorber between the light bulb holder and the light bulb. As shown in FIG. 1, the existing automobile headlight includes a base 3 that can be fixedly connected to the car through a connecting member 2, and a base 3 that can be detachably connected to the base 3 through a connecting member 20. A gasket 9 in the middle of the outer casing 4, a transparent cover 8 provided inside the outer casing 4, and a light bulb 1 connected to the light bulb holder 5. The bulb holder 5 is integrally formed at the middle portion of the base 3, and a shock absorber 7 is provided at the inner bottom of the bulb holder 5. At the same time, the shock absorber 提供 is used to provide the positive and negative power sources for the bulb 1. The shock absorber 7 includes a compression spring 70, and the compression spring 70 can be used to relieve the vibration of the bulb 1 in the axial direction and reduce the damage rate of the bulb 1. However, after using the shock absorber 7, the light bulb 1 can only act as a shock absorber in the axial direction, that is, the front-rear direction of the vehicle, and cannot make the light bulb 1 play a cushioning role in the radial direction. In the actual process, the vehicle The bump affects the light bulb 1 more in the radial direction, and the vibration in the radial direction is the main factor that affects the damage of the light bulb. Therefore, the currently used car lights still have a large damage rate. The problem of excessive cost. In view of this, the creator of the present invention, with his many years of experience and practice in related industries, and after intensive research and development, has finally created a method that can have better shock absorption in both axial and radial directions. And can be installed in different vehicle headlights. Summary of the invention
