[0022] 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.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: a heat dissipation structure of an automotive LED headlamp, comprising a shell 1, a fixed block 4 is fixedly connected to the left and right sides of the shell 1, a limiting groove 8 is provided inside the fixed block 4, a spring 9 is fixedly connected to the inside of the limiting groove 8, the other end of the spring 9 is fixedly connected to the limiting block 10, a pull rod 11 is fixedly connected to one side of the limiting block 10, and a clamping block 12 is fixedly connected to the other side of the limiting block 10, a filter screen 5 is installed on the inner side of the bottom of the shell 1, and a clamping groove 13 is provided on the left and right sides of the filter screen 5, a plurality of heat dissipation fins 6 are fixedly connected to the top of the shell 1, the outside of the clamping block 12 is clamped with the inside of the clamping groove 13 on an adjacent side, the outside of the limiting block 10 is slidably connected to the inside of the fixed block 4, and the spring 9 is sleeved on the outside of the pull rod 11.

[0024] Specifically, the two fixing blocks 4 are fixed on the left and right sides respectively through the outer shell 1, and then a snap-in assembly can be installed through the fixing block 4, so that the filter 5 can be installed on the inner bottom of the outer shell 1, so as to reduce the influence of dust entering the inner part of the outer shell 1 on heat dissipation. By pulling the pull rod 11 outside the fixing block 4, the limit block 10 can be driven to slide inside the limit groove 8, and the limit groove 8 will limit the limit block 10 so that the limit block 10 can maintain horizontal movement, so that the limit block 10 compresses the spring 9 and drives the clamping block 12 to disengage from the clamping groove 13, thereby realizing the disassembly of the filter 5, facilitating the cleaning of the fan 16 and the filter 5 inside the outer shell 1, avoiding excessive dust from affecting the heat dissipation effect of the fan 16 and the dustproof effect of the filter 5, so that the heat of the LED headlamp can be discharged stably, and the heat dissipation of the heat inside the outer shell 1 can be accelerated through multiple heat dissipation fins 6, thereby improving the heat dissipation effect.

[0025] Reference Figure 1 and Figure 2A cleaning assembly is provided on the outer side of the top of the housing 1. The cleaning assembly is used to clean the heat dissipation fins 6. The cleaning assembly includes a gear ring 17. The gear ring 17 is fixedly connected to the outer side of the top of the housing 1. The outer side of the gear ring 17 is slidably connected to a moving frame 18. A micro motor 19 is installed at the bottom of the moving frame 18. A gear 20 is fixedly connected to the output end of the micro motor 19. An L-shaped rod 7 is fixedly connected to the top of the moving frame 18. The gear 20 is rotatably connected to the inner side of the moving frame 18, and the outer side of the gear 20 is meshed with the outer side of the gear ring 17.

[0026] Specifically, fixing the micro motor 19 at the bottom of the moving frame 18 can keep the micro motor 19 stable during operation, thereby driving the gear 20 to rotate. Since the gear 20 is meshed with the gear ring 17, the gear 20 moves during rotation and drives the moving frame 18 to rotate around the gear ring 17. The L-shaped rod 7 is driven to move by the moving frame 18, so that the brush fixed on the surface of the L-shaped rod 7 can brush off the dust on the surface of the cooling fin 6, so that the cooling effect will not be affected by the accumulation of dust on the surface of the cooling fin 6, thereby improving the cooling efficiency and allowing the LED headlamp to maintain stable heat dissipation.

[0027] Reference Figure 4 The top of the shell 1 is fixedly connected with a connecting base 2, the top of the connecting base 2 is fixedly connected with an LED lamp body 3, the inner top of the shell 1 is fixedly connected with a heat sink 15, the inside of the shell 1 is fixedly connected with a fan 16, and a plurality of heat dissipation holes 14 are opened on the surface of the shell 1.

[0028] Specifically, by connecting the connecting base 2 with the outer shell 1, and installing the LED lamp body 3 on the top of the connecting base 2, the heat emitted by the LED lamp body 3 during operation can be transferred to the inside of the outer shell 1 through the connecting base 2, and then the heat is discharged, thereby cooling the connecting base 2, avoiding damage to the internal components of the LED headlamp caused by high temperature, and extending its service life. The heat dissipation area is increased through the heat dissipation plate 15, the heat transfer efficiency is accelerated, and the heat is discharged through the fan 16. The multiple heat dissipation holes 14 can accelerate the air circulation of the outer shell 1, further improving the heat dissipation.

[0029] Working principle: By starting the fan 16, the heat generated by the LED lamp body 3 during operation can be transferred to the inside of the housing 1 through the connecting seat 2, and the heat dissipation area can be expanded under the action of the heat dissipation plate 15, so that the fan 16 can discharge the heat, accelerate the heat dissipation speed of the lighting lamp, and discharge the heat in time, thereby avoiding damage to the internal components of the LED lamp caused by excessive temperature. By pulling the pull rod 11 outside the fixing block 4, the limit block 10 can be driven to slide inside the limit groove 8, so that the limit block 10 compresses the spring 9, and at the same time drives the card block 12 to separate from the card groove 13, and then the filter 5 can be removed from the housing 1 The inner side of the housing 1 can be disassembled, so that the fan 16 and the filter 5 inside the housing 1 can be cleaned to prevent excessive dust from affecting the heat dissipation effect of the fan 16 and the dust-proof effect of the filter 5, so that the heat of the LED headlamp can be discharged stably. By starting the micro motor 19, the gear 20 can be driven to rotate. Through the engagement of the gear 20 with the gear ring 17, the moving frame 18 can move around the gear ring 17, and then the L-shaped rod 7 can be driven to move. The dust on the surface of the heat dissipation fin 6 can be brushed off by the brush fixed on the L-shaped rod 7, thereby improving the heat dissipation effect of the heat dissipation fin 6 and preventing dust accumulation from causing the heat dissipation effect of the housing 1 to deteriorate.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
