Description

Technical Field

[0001] This utility model relates to the field of vehicle lamp heat dissipation, specifically a vehicle lamp heat dissipation structure. Background Technology

[0002] Automotive lights generate a lot of heat when they are working. For example, the photoelectric conversion efficiency of LED chips is only about 20%-30%, and the remaining energy is released as heat. If the heat cannot be dissipated in time, the LED junction temperature (TJ) will rise, which will lead to accelerated light decay, wavelength shift, and even circuit failure.

[0003] In automotive radiators, multiple pluggable heat sinks are often used, connected to the heat sink base. A cooling fan is installed on one side of the heat sink. During long-term use, it is necessary to clean the dust adhering to the heat sink to ensure heat dissipation efficiency. In order to facilitate the cleaning of the heat sink, this utility model proposes a vehicle headlight heat dissipation structure. Utility Model Content

[0004] The purpose of this utility model is to provide a heat dissipation structure for vehicle lights in order to solve the problems mentioned in the background above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vehicle lamp heat dissipation structure, including a vehicle lamp holder, and a heat dissipation seat connected to one end of the vehicle lamp holder for guiding the heat generated by the vehicle lamp holder. A heat dissipation fan is spliced ​​on one side of the heat dissipation seat to cool down the heat absorbed by the heat dissipation seat. The structure also includes a limiting mechanism provided on the vehicle lamp holder and the heat dissipation fan for limiting the installation of the heat dissipation fan.

[0006] The limiting mechanism includes a limiting unit and a docking unit;

[0007] The docking unit is used for pre-connection of the headlight socket and cooling fan;

[0008] The limiting unit is used to limit the pre-connected headlight socket and cooling fan.

[0009] As a further embodiment of this utility model: the docking unit includes a docking rod and a fixing seat;

[0010] The three connecting rods are evenly distributed circumferentially on the outer wall of the cooling fan, and the three connecting rods respectively pass through the three fixing seats fixed to the outer wall of the headlight housing. The connecting rods and fixing seats are used to provide limits for the splicing of the headlight housing and the cooling fan.

[0011] As a further embodiment of this utility model: the limiting unit includes a movable rod, a movable ring, a spring, a guide groove, and a limiting block;

[0012] The movable rod is axially slidably installed in the inner cavity of the docking rod. The outer wall of the movable rod extends to the outside of the docking rod and is fixed to the inner side of the movable ring through a connecting block. The movable ring is used to apply a compressive force to one end of the spring connected to the outer wall as the movable rod moves. The two ends of the spring are respectively connected to the movable ring and the outer wall of the docking rod. The spring is used to always apply a compressive force to the movable ring in one direction. The guide groove is opened in the inner cavity of the movable rod. The limiting block is vertically slidably installed in the inner cavity of the docking rod and its upper and lower ends extend to the outside of the docking rod and the inner side of the movable rod, respectively. The outer wall of the limiting block is fixed with a protrusion extending into the inner cavity of the guide groove.

[0013] As a further embodiment of this utility model: the protrusion fixed to the outer wall of the limiting block is cylindrical and matches the inner cavity of the guide groove, and the outer wall of the guide groove is inclined as a whole.

[0014] As a further improvement of this utility model, the outer wall of the connecting rod is formed with a groove for the axial movement of the connecting block fixed inside the movable ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting a limiting mechanism, when it is necessary to clean the heat sinks inserted on multiple heat sink bases, the limiting block can be moved from the outside of the fixed base to the inside of the connecting rod by pressing the end of the movable rod, thereby disengaging the cooling fan from the heat sink base and facilitating the cleaning of the multiple heat sinks inserted on the heat sink base, thus further improving work efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 In this embodiment of the utility model, a vehicle lamp heat dissipation structure includes a vehicle lamp holder 1, a heat dissipation seat 2 connected to one end of the vehicle lamp holder 1 for guiding the heat generated by the vehicle lamp holder 1, a heat dissipation fan 3 for cooling the heat absorbed by the heat dissipation seat 2 is spliced ​​on one side of the heat dissipation seat 2, and a limiting mechanism 4 provided on the vehicle lamp holder 1 and the heat dissipation fan 3 for providing a limit for the installation of the heat dissipation fan 3.

[0023] The limiting mechanism 4 includes a limiting unit and a docking unit;

[0024] The docking unit is used for pre-connection of the headlight socket 1 and the cooling fan 3;

[0025] The limiting unit is used to limit the pre-connected headlight mount 1 and cooling fan 3;

[0026] The docking unit includes a docking rod 401 and a fixing seat 407;

[0027] Three connecting rods 401 are evenly distributed around the outer wall of the cooling fan 3, and the three connecting rods 401 respectively pass through the three fixing seats 407 fixed to the outer wall of the headlight seat 1. The connecting rods 401 and the fixing seats 407 are used to provide limits for the splicing of the headlight seat 1 and the cooling fan 3.

[0028] The limiting unit includes a movable rod 402, a movable ring 403, a spring 404, a guide groove 405, and a limiting block 406;

[0029] The movable rod 402 is axially slidably installed in the inner cavity of the docking rod 401. The outer wall of the movable rod 402 extends to the outside of the docking rod 401 through the connecting block and is fixed to the inner side of the movable ring 403. The movable ring 403 is used to apply a compressive force to one end of the spring 404 connected to the outer wall as the movable rod 402 moves. The two ends of the spring 404 are respectively connected to the movable ring 403 and the outer wall of the docking rod 401. The spring 404 is used to always apply a compressive force to the movable ring 403 in one direction. The guide groove 405 is opened in the inner cavity of the movable rod 402. The limiting block 406 is vertically slidably installed in the inner cavity of the docking rod 401 and its upper and lower ends extend to the outside of the docking rod 401 and the inner side of the movable rod 402, respectively. The outer wall of the limiting block 406 is fixed with a protrusion extending to the inner cavity of the guide groove 405.

[0030] In this embodiment: This structure allows for axial movement of the movable rod 402 when cleaning of the heat sink 2 is required. This causes the portion of the movable rod 402 exposed at one end of the docking rod 401 to enter the interior of the docking rod 401. Simultaneously, the axially moving movable rod 402 drives the guide groove 405 and the movable ring 403 to move axially. The movable ring 403 moves axially along the outer side of the docking rod 401 and is subjected to compressive force by the spring 404. The guide groove 405 also applies oblique compressive force to the outer wall protrusion of the limiting block 406, causing the limiting block 406 to enter the interior of the docking rod 401 and the movable rod 402 along the inclined direction of the guide groove 405. This releases the limiting of the fixed seat 407 and the limiting block 406, making it easier to directly pull the docking rod 401 out of the inner cavity of the fixed seat 407, exposing the heat sink 2 for cleaning.

[0031] Please refer to this carefully. Figures 1-3 The protrusion fixed to the outer wall of the limiting block 406 is cylindrical and matches the inner cavity of the guide groove 405. The outer wall of the guide groove 405 is inclined as a whole.

[0032] In this embodiment: This structure can synchronously drive the guide groove 405 to move axially when the movable rod 402 moves axially, so that the outer wall protrusion of the limiting block 406 connected to the inner cavity of the guide groove 405 enters the interior of the docking rod 401 and the movable rod 402 along the inclined direction of the guide groove 405.

[0033] Please refer to this carefully. Figures 1-3 The outer wall of the connecting rod 401 is formed with a groove for the axial movement of the connecting block that is fixed inside the movable ring 403.

[0034] In this embodiment: with this structure, the movable ring 403 can be moved axially along the outer side of the docking rod 401 by the connecting block under the push of the movable rod 402.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
