DETAILED DESCRIPTION
[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0035] Embodiment 1: When the existing automobile headlight is in use, the lampshade and the lamp body are usually rigidly connected, and there is no corresponding buffer structure between the two. When the lampshade is hit by an external force, it is easy to cause the lampshade to be damaged due to excessive impact force. In order to solve this technical problem, this embodiment discloses the following technical contents, such as Figure 1-Figure 5 ;
[0036] A car headlight that is easy to repair, comprising a lamp body 1, a lampshade 2 is arranged on the front side of the lamp body 1, and a sealing ring 3 is fixedly connected between the lamp body 1 and the lampshade 2; positioning blocks 4 are fixedly installed on the left and right sides of the lamp body 1, and a guide rod 5 is fixedly connected to the positioning block 4, the guide rod 5 is installed through the locking plate 7, and the locking plate 7 is connected to the positioning block 4 through an adjustment spring 6, and the side of the lampshade 2 is connected to the locking plate 7 through a positioning bolt 8; the sealing ring 3 is set to an elastic rubber material, and the shape of the sealing ring 3 is adapted to the shape of the lampshade 2. The inner wall of the locking plate 7 and the outer wall of the guide rod 5 fit each other, and the locking plate 7 forms an elastic telescopic structure through the adjustment spring 6 and the positioning block 4.
[0037] The sealing ring 3 is fixed to the lamp body 1 and the lampshade 2 by bonding. When the lamp beads and other parts inside the lamp body 1 need to be inspected and repaired, the positioning bolts 8 are turned to release the fixation between the lampshade 2 and the locking plate 7. Then the lampshade 2 and the sealing ring 3 can be pulled off the lamp body 1 to complete the disassembly, which is convenient for the inspection of the internal components of the lamp body 1. After the inspection is completed, the sealing ring 3 can be adhered between the lamp body 1 and the lampshade 2 with glue again. When the lampshade 2 is hit by an external force, the impact force is first released from the lampshade 2. At this time, the lampshade 2 can deform the sealing ring 3 after being subjected to force. At the same time, the lampshade 2 can move the locking plate 7 connected by the positioning bolts 8 on the guide rod 5 after being subjected to force. Through the movement of the locking plate 7 on the guide rod 5, the elastic deformation of the adjustment spring 6 can be used to play a buffering role to avoid damage to the lampshade 2 caused by excessive impact force.
[0038] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. In order to facilitate heat dissipation, the automobile headlight is provided with a corresponding heat dissipation aluminum sheet. However, after long-term use, a large amount of dust and impurities are easily attached to the surface of the heat dissipation aluminum sheet. As a large amount of dust and impurities are attached and cannot be cleaned, it is easy to affect the heat exchange effect between the heat dissipation aluminum sheet and the outside air. In order to solve this technical problem, this embodiment discloses the following technical content, such as Figure 4-Figure 6 As shown;
[0039] A heat absorbing plate 9 is fixedly connected to the back of the lamp body 1, and a heat radiating fin 10 for heat exchange with the outside air is fixedly installed on the outside of the heat absorbing plate 9, and a temperature control cleaning mechanism 11 is installed on the heat radiating fin 10, and the temperature control cleaning mechanism 11 is used to clean the dust on the surface of the heat radiating fin 10. The heat radiating fins 10 are evenly distributed on the heat absorbing plate 9 at equal intervals, and the heat radiating fins 10 and the heat absorbing plate 9 are an integrally formed structure. The temperature control cleaning mechanism 11 includes a guide rod 111, a moving plate 112, a cleaning groove 113 and a memory metal wire 114, and the guide rod 111 is fixed to the middle of the back of the lamp body 1, and the guide rod 111 is installed through the middle of the moving plate 112, and the moving plate 112 is provided with a cleaning groove 113, and a memory metal wire 114 is installed between the moving plate 112 and the heat absorbing plate 9. The moving plate 112 and the guide rod 111 are slidably connected, and the number of the cleaning grooves 113 is equal to the number of the heat radiating fins 10. The memory metal wires 114 are symmetrically arranged about the transverse center axis of the movable plate 112 , and the symmetrically distributed memory metal wires 114 are all arranged in a spiral structure.
[0040] When the lamp body 1 is heated, the heat can be absorbed by the heat absorbing plate 9. After absorbing the heat, the heat absorbing plate 9 contacts with the outside air through the heat dissipation fins 10, thereby dissipating the heat outward, thereby cooling the lamp body 1. After absorbing the heat, the heat absorbing plate 9 can transfer the heat to the memory wire 114. The memory wire 114 shrinks after absorbing the heat. At this time, the shrinking memory wire 114 pulls the movable plate 112 to move on the guide rod 111. After the movable plate 112 moves, the cleaning groove 113 thereon can be used to effectively clean the dust and impurities attached to the surface of the heat dissipation fins 10, so as to avoid the adhesion of too much dust on the heat dissipation fins 10 and affect the heat exchange effect. When the temperature of the lamp body 1 and the heat absorbing plate 9 returns to normal, the memory wire 114 recovers through its own characteristics. The recovered memory wire 114 also pushes the movable plate 112 to reset, so as to facilitate the next mobile cleaning use.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
