[0012] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described below are only used to explain the utility model, and in these descriptions, the key words to be noted include "damper", "damping liquid", etc. These are only used to facilitate the description of the utility model and simplify the description, and therefore cannot be understood as a limitation on the utility model.

[0013] In the design process of an automobile lamp, if the positions of the support and the shell fixed by screws are not correct or the number of the screws is not enough, there is a risk of breakage between the two parts of the automobile lamp, and there may be a problem of powdering. After breakage, the entire automobile lamp is disabled and cannot be used. The problem of powdering has visible problems in appearance, which is a serious design failure. More seriously, breakage and damage may occur between the shell and the support, resulting in product failure.

[0014] The utility model discloses an automobile lamp spring damper, which is shown in the figure and can be divided into two buffering and damping parts. Figures 1-2 The first part adopts a high-quality spring 2, and the second part adopts a damper 4. The two are combined, and specifically include an upper plate 1, a spring 2, a lower plate 3, a damper 4 and a bottom plate 5. The damper 4 includes a shell, a piston rod 41 and a piston head 42. The shell is provided with a piston skirt and forms a closed cavity 44. One end of the piston rod 41 is fixedly connected with the piston head 42 and is installed in the cavity 44. The piston head 42 is provided with a through hole flow-through hole 43 (as shown by the dashed line in the figure). The cavity 44 is filled with damping liquid. The damper 4 is fixedly installed on the bottom plate 5. The other end of the piston rod 41 is fixedly connected with the lower plate 3. The lower part of the spring 2 is fixedly connected with the upper surface of the lower plate 3, and the upper part of the spring 2 is fixedly connected with the lower surface of the upper plate 1. Figure 2 The bottom plate 5 of the automobile lamp spring damper of the embodiment is fixedly and connectively installed on the support of the automobile lamp, and the upper surface of the upper plate 1 is fixedly and connectively installed with the shell of the automobile lamp.

[0015] The utility model discloses when using, in the normal driving of car on the relatively gentle road surface, can buffer a part of external excitation by spring 2, the structure of spring 2 is relatively simple, easy to manufacture and maintain, the use rate of spring 2 is higher under general conditions, and the support of support and shell is great, can provide certain buffer, and it is helpful to keep the stability of car light. The utility model discloses its core is when meeting the road surface condition of jolting, can start using damper 4, utilizes spring 2 to add damper 4 to buffer the excessive external excitation that spring 2 cannot bear, can effectively reduce the vibration of light fitting in driving, improves light fitting safety. In order to make the utility model discloses use effect to be enhanced, designs a kind of spring damper suitable for the narrow interior space of car light, and can utilize different methods to adjust the utility model to adapt to different road surface conditions, first, the rigidity of spring can be adjusted, the rigidity, length etc. of spring can be adjusted, provide an original support for car light, also can adjust the self characteristic of damping liquid in damper, such as selecting different viscous resistance damping liquid of silicon oil or glycerol etc. Still can be adjusted according to use scene and position, such as placing the damper between support and lamp shell, or between small support and big support.

[0016] Specific as follows:

[0017] Step 1: select high-quality spring 2, on the one hand can support the weight of car light itself, another aspect can also utilize the self characteristic of spring 2 to slow down a part of external vibration input.

[0018] Step 2: utilize the movement of damper 4 piston (piston rod 41 and piston head 42) to control the flow of damping liquid, when spring 2 cannot accept all external excitation, the piston is compressed to move downward, and the damping liquid enters the upper cavity through the flow hole 43 in the middle of the plug 42, to produce damping effect. When external excitation disappears, because spring 2 will spontaneously reset, the restoring force of spring 2 will pull the piston upward, so that the damper 4 resets, and the damping liquid, piston and spring 2 inside the damper 4 cooperate to transform and absorb the energy of external jolting, which can improve the stability of the entire light fixture of car light.

[0019] The above only describes the general embodiment of the utility model, and the utility model can have various changes and other embodiments for those skilled in the art, which are not described here. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model is included in the protection scope required by the utility model.
