DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 5 As shown, in this embodiment, a heat dissipation assembly for a car lamp includes a central column 1, a plurality of heat dissipation fins 2 are fixedly connected to the outer wall of the central column 1, and the plurality of heat dissipation fins 2 are in a ring array. A mounting groove 3 is provided at the front end of the central column 1, and the mounting groove 3 is used to install the car lamp. A heat dissipation fan is provided at the rear end of the mounting groove 3. The heat dissipation fan is connected to the central column 1 through a connecting mechanism. The connecting mechanism is composed of a connecting column 9, a positioning column 10 and a limiting rod 11. The connecting column 9 is fixedly connected to the positioning column 10. One end of the fan is rotatably connected to the center position of the axial end of the positioning column 10, a connecting groove 16 is provided at the rear end of the center column 1, a positioning groove 17 is provided at the opening position of the connecting groove 16, the connecting groove 16 and the connecting column 9 are connected by threaded cooperation, the positioning column 10 and the positioning groove 17 are slidably fitted, a limiting rod 11 is provided at the side end of the positioning column 10, a reset mechanism acting on the limiting rod 11 is provided inside the positioning column 10, and a limiting groove 15 is provided on the inner wall of the positioning groove 17 with which the limiting rod 11 is slidably fitted.

[0022] Among them, the reset mechanism is composed of a movable block 12 and a spring 14. The movable block 12 is slidably installed in a movable groove 13 opened in the positioning column 10. The spring 14 is fixedly connected between one end of the movable block 12 close to the axis of the positioning column 10 and the inner wall of the movable groove 13. The other end of the movable block 12 is fixedly connected to the limiting rod 11. The other end of the limiting rod 11 slides through the positioning column 10 and extends to the outside of the positioning column 10.

[0023] With such arrangement, the limiting rod 11 can be extended and retracted in the movable slot 13 , and the spring 14 can ensure that the limiting rod 11 can automatically extend out of the movable slot 13 .

[0024] Among them, the cooling fan is composed of a rotating shaft 7 and cooling blades 5, a plurality of cooling blades 5 are fixedly connected to the outer surface of the rotating shaft 7, and the plurality of cooling blades 5 are in a ring array, a driving motor is arranged inside the connecting column 9, and the output shaft of the driving motor is fixedly connected to the rotating shaft 7.

[0025] The driving motor can drive the rotating shaft 7 to rotate, thereby driving the heat dissipation blades 5 to rotate.

[0026] The front end of the central column 1 is fixedly connected to a first limit block 4 , one end of the rotating shaft 7 away from the central column 1 is rotatably connected to a rear side plate 8 , and the other end of the rear side plate 8 is fixedly connected to a second limit block 6 .

[0027] The first limiting block 4 and the second limiting block 6 can be matched with the inner cavity of the automobile lamp housing, so as to facilitate the installation of the heat dissipation assembly.

[0028] The limiting groove 15 runs across the central column 1 .

[0029] With such arrangement, when the heat dissipation fan needs to be disassembled, the peripheral thin rod can be inserted into the limiting groove 15 on the outer wall of the central column 1, so that the limiting rod 11 is pushed out of the limiting groove 15, which facilitates the disassembly of the heat dissipation fan.

[0030] The end of the limiting rod 11 is in a truncated cone shape.

[0031] Such a configuration can facilitate the insertion of the limiting rod 11 into the limiting groove 15 .

[0032] The utility model provides a heat dissipation component for automobile lamps, and the specific working principle is as follows:

[0033] When in use, press the limit rod 11 into the movable groove 13 by hand. At this time, the spring 14 will be squeezed, and the cooling fan will be installed on the rear end of the center column 1 through the threaded cooperation of the connecting column 9 and the connecting groove 16. When the positioning column 10 enters the positioning groove 17, release the limit rod 11. At this time, the inner wall of the positioning groove 17 will resist the limit rod 11 to ensure that the limit rod 11 will not extend out of the movable groove 13. When the positioning column 10 is completely immersed in the positioning groove 17, the limit rod 11 will be just aligned with the limit groove 15. Under the action of the spring 14 restoring the deformation, the limit rod 11 will be inserted into the limit groove 15, thereby ensuring that the cooling fan and the center column 1 will not rotate, and the threaded connection between the connecting column 9 and the connecting groove 16 will not loosen, thereby ensuring the stability of the connection between the cooling fan and the center column 1. This connection method is simple to operate and easy to disassemble and assemble, and there is no need to worry about the connection loosening due to the rotation of the cooling fan.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
