Description

Technical Field

[0001] This utility model relates to the technical field of automotive headlight structure, and in particular to an LED automotive headlight structure. Background Technology

[0002] In the context of low-carbon and environmentally friendly development, automobiles are an indispensable part of life. Car headlights are like human eyes, ensuring driving safety. Compared to traditional halogen and xenon lamps, LED lights have advantages such as high luminous efficiency, low energy consumption, high reliability, long lifespan, environmental friendliness, and small size. Currently, LED lights are widely used as car headlights.

[0003] Chinese Patent Publication No. CN219328024U discloses an LED light source structure for automotive headlights, including a main body. A connecting plate is provided at the lower end of the main body. An insert plate is provided on the lower surface of the connecting plate. A conductor is provided on the inner side of the insert plate. A working groove is provided on the inner side of the main body. A heat insulation plate is provided on the inner wall of the working groove. Grooves are uniformly provided on the outer surface of the heat insulation plate. Heat dissipation holes are provided at the lower end of the grooves. A positioning plate is provided on the inner side of the working groove. An mounting groove is uniformly provided on one side of the positioning plate. Cooling pipes are uniformly provided on the outer side of the mounting groove. A connecting groove is provided on the inner side of the positioning plate. A heating mesh is provided on the inner side of the connecting groove. A fan is provided at the upper end of the heating mesh. A coolant tank is uniformly provided on the outer side of the positioning plate. The coolant tank and the cooling pipes are connected by a connecting pipe.

[0004] In this existing design, although the connecting groove, fan, and heating grid inside the positioning plate can reduce the impact of fog caused by temperature differences on the lighting and improve the lighting effect of the car, and the heat insulation plate and heat dissipation holes on the inner wall of the working groove can reduce the impact of external temperature on the inner side of the working groove and increase the ventilation and heat dissipation of the working groove, thereby improving the service life of the device, and the cooling pipes on the outer surface of the mounting groove and the coolant tank inside the positioning plate can effectively dissipate heat from the installed LED lights to prevent overheating and damage to the LED lights, the use of cooling pipes and coolant tanks for cooling and heat dissipation increases the production cost of the car lights. And the heat dissipation effect of only using the heat insulation plate and heat dissipation holes is generally poor, and when the heat dissipation structure needs maintenance, the entire heat insulation plate needs to be removed, which is inconvenient for cleaning and maintenance.

[0005] Therefore, an LED automotive headlight structure was designed to solve the above problems. Summary of the Invention

[0006] To address the problems mentioned in the background section, this utility model provides an LED automotive headlight structure that features individually detachable and replaceable heat sinks, facilitating cleaning and maintenance.

[0007] This utility model adopts the following technical solution: an LED automotive headlight structure, including a main body, a connecting plate installed at the lower end of the main body, an insert plate installed on the lower surface of the connecting plate, a conductor provided on the inner side of the insert plate, a heat insulation plate installed on the inner wall of the main body, a front cover threadedly connected to the top of the main body, a fixing block installed inside the main body, a lamp body installed inside the fixing block, and a heat dissipation mechanism provided on the inner wall of the heat insulation plate. The heat dissipation mechanism includes a mounting groove, a spring, and a heat dissipation fin. The mounting groove is formed on the inner wall of the heat insulation plate, the spring is installed on the inner wall of the heat insulation plate through the mounting groove, and the heat dissipation fin is clamped and fixed inside the main body by the spring.

[0008] The shape and size of the spring and the mounting groove are matched, and an anti-slip pad is fixedly installed on the surface of the spring clamping arm.

[0009] The number of mounting slots, springs, and heat sinks is equal, and the mounting slots, springs, and heat sinks are all distributed in a circumferential array inside the main body.

[0010] The inner wall of the spring sheet is provided with a slot, and a block is fixedly installed on the side of the heat sink. Both the block and the slot are circular, and the block and the slot are positioned opposite each other.

[0011] The top surface of the heat insulation board is provided with a release mechanism, which includes a groove, a through groove, and a connecting rod. The groove is formed on the top surface of the heat insulation board, and the through groove passes through the groove, the mounting groove, and the spring piece. The connecting rod is inserted into the groove and the spring piece through the through groove.

[0012] A push plate is fixedly installed at one end of the connecting rod, and an extrusion plate is fixedly installed at the other end of the connecting rod.

[0013] A spring is fitted onto the surface of the connecting rod. One end of the spring is fixedly connected to the inner wall of the groove, and the other end of the spring is fixedly connected to the surface of the push plate.

[0014] A reinforcing block is fixedly installed between the extrusion plate and the connecting rod. There are two sets of reinforcing blocks, and the two sets of reinforcing blocks are symmetrically distributed on the surface of the connecting rod.

[0015] The extrusion plate has chamfers on both sides, and the chamfers are parallel to the inner wall of the spring sheet.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: a heat dissipation mechanism is set up, and the heat dissipation fins are fixed to the inner wall of the heat insulation plate by spring tabs. The heat dissipation fins are distributed in a circumferential array on the inner wall of the heat insulation plate, which improves the heat dissipation effect.

At the same time, the structure is simple and easy to operate. A release mechanism is also set up. Simply push the push plate to open the clamping arm of the spring tab, which makes it easier for the user to remove the heat dissipation fins, shortens the loading and unloading time, and further improves maintenance efficiency.

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0033] In the existing technology, the existing automotive headlight structure includes a main body 1, a connecting plate 2 installed at the lower end of the main body 1, an insert plate 3 installed on the lower surface of the connecting plate 2, a conductor 4 provided on the inner side of the insert plate 3, and a heat insulation plate 5 installed on the inner wall of the main body 1. This automotive headlight structure also has grooves uniformly arranged on the outer surface of the heat insulation plate, heat dissipation holes provided at the lower end of the grooves, a positioning plate provided on the inner side of the working groove, mounting grooves uniformly arranged on one side of the positioning plate, cooling pipes uniformly arranged on the outer side of the mounting groove, and a connecting groove provided on the inner side of the positioning plate. A heating grid is installed on the inner side of the connecting groove, and a fan is installed at the upper end of the heating grid. Coolant tanks are evenly arranged on the outer side of the positioning plate. The coolant tanks are connected to the cooling pipes through connecting pipes. Through the connecting groove, fan, and heating grid installed on the inner side of the positioning plate, the impact of fog caused by temperature difference on the lighting can be reduced, thus improving the lighting effect of the car. A heat insulation plate and heat dissipation holes are installed on the inner wall of the working groove. The heat insulation plate and heat dissipation holes reduce the impact of external temperature on the inner side of the working groove and increase the ventilation and heat dissipation of the working groove.

[0034] This application incorporates the aforementioned prior art, such as Figures 1 to 8As shown, this utility model provides a technical solution: an LED automotive headlight structure, with a front cover 6 threadedly connected to the top of the main body 1, a fixing block 7 installed inside the main body 1, a lamp body 10 installed inside the fixing block 7, and a heat dissipation mechanism 9 provided on the inner wall of the heat insulation plate 5. The heat dissipation mechanism 9 includes a mounting groove 901, a spring 902, and a heat dissipation fin 903. The mounting groove 901 is opened on the inner wall of the heat insulation plate 5, the spring 902 is installed on the inner wall of the heat insulation plate 5 through the mounting groove 901, and the heat dissipation fin 903 is clamped and fixed inside the main body 1 by the spring 902.

[0035] In this implementation scheme: a heat dissipation mechanism 9 is provided on the inner wall of the heat insulation plate 5. The heat dissipation effect of the device can be improved by the heat dissipation fins 903. At the same time, the heat dissipation fins 903 are fixed by spring tabs 902. The installation method is simple and easy to disassemble, while avoiding increased production costs. The heat dissipation fins 903 can be removed from the inner wall of the heat insulation plate 5 simply by opening the spring tabs 902. When a single heat dissipation fin 903 is damaged, it can be replaced by disassembling the damaged heat dissipation fin 903 individually, which improves maintenance efficiency.

[0036] Combining the above solutions:

[0037] Furthermore:

[0038] like Figure 3 , Figure 4 and Figure 7 As shown;

[0039] In order to prevent the clamping arm of the spring 902 from damaging the surface of the heat sink 903, in an optional embodiment, the spring 902 and the mounting groove 901 are matched in shape and size, and an anti-slip pad 904 is fixedly installed on the surface of the clamping arm of the spring 902.

[0040] In this embodiment: the spring 902 is fixed by the mounting slot 901, which can limit the movement of the spring 902 and prevent it from moving violently during vehicle operation, thus affecting the fixation of the heat sink 903. The anti-slip pad 904 is installed on the surface of the spring 902. On the one hand, it can increase the friction between the spring 902 and the heat sink 903, thereby better fixing the heat sink 903. On the other hand, it can protect the surface of the heat sink 903 and prevent the clamping arm of the spring 902 from damaging the surface of the heat sink 903 during the clamping process.

[0041] Combining the above solutions:

[0042] Furthermore:

[0043] like Figures 3 to 5 As shown;

[0044] To improve heat dissipation, in an optional embodiment, the number of mounting slots 901, springs 902, and heat sinks 903 are equal, and the mounting slots 901, springs 902, and heat sinks 903 are all distributed in a circumferential array inside the main body 1.

[0045] In this embodiment, the mounting slot 901, the spring piece 902, and the heat sink 903 are fixed in a circumferential array inside the main body 1, which can improve the heat dissipation effect to a certain extent, avoid affecting the use effect of the lamp body 10, and at the same time, prevent the lamp body 10 from generating fog that obstructs the front cover 6 when it is used for a long time.

[0046] Combining the above solutions:

[0047] Furthermore:

[0048] like Figures 7 to 8 As shown;

[0049] In an optional embodiment, in order to limit the spring 902, a slot 905 is provided on the inner wall of the spring 902, and a block 906 is fixedly installed on the side of the heat sink 903. Both the block 906 and the slot 905 are circular, and the positions of the block 906 and the slot 905 are opposite.

[0050] In this embodiment, a locking block 906 and a locking slot 905 are provided to limit the heat sink 903 inside the spring piece 902. This allows the user to judge whether the heat sink 903 is installed correctly by checking the degree of engagement between the locking block 906 and the locking slot 905, which can improve the installation efficiency of the heat sink 903 to a certain extent.

[0051] Combining the above solutions:

[0052] Furthermore:

[0053] like Figure 3 , Figure 4 and Figure 9 As shown;

[0054] To facilitate the rapid release of the heat sink 903, in an optional embodiment, a release mechanism 8 is provided on the top surface of the heat insulation plate 5. The release mechanism 8 includes a groove 801, a through groove 802, and a connecting rod 803. The groove 801 is formed on the top surface of the heat insulation plate 5. The through groove 802 passes through the groove 801, the mounting groove 901, and the spring piece 902. The connecting rod 803 is inserted into the groove 801 and the spring piece 902 through the through groove 802.

[0055] In this embodiment, a release mechanism 8 is provided. The connecting rod 803 can further fix the spring 902 and the mounting groove 901. At the same time, a pressing plate 805 is installed at one end of the connecting rod 803, which can facilitate the opening of the spring 902 to achieve the effect of quickly releasing the heat sink 903 and further improve the disassembly efficiency of the heat sink 903.

[0056] Combining the above solutions:

[0057] Furthermore:

[0058] like Figure 9 As shown;

[0059] To facilitate the opening of the spring sheet 902, in an optional embodiment, a push plate 804 is fixedly installed at one end of the connecting rod 803, and a compression plate 805 is fixedly installed at the other end of the connecting rod 803.

[0060] In this embodiment: by pushing the push plate 804, the push plate 804 drives the connecting rod 803 to move, and at the same time the connecting rod 803 drives the pressing plate 805 to move until both sides of the pressing plate 805 come into contact with the spring piece 902. By continuously pushing the connecting rod 803, the spring piece 902 can be opened, which can replace manual opening of the spring piece 902 and improve disassembly efficiency.

[0061] Combining the above solutions:

[0062] Furthermore:

[0063] like Figure 3 and Figure 9 As shown;

[0064] In an optional embodiment, to enable the extrusion plate 805 to automatically reset, a spring 806 is fitted onto the surface of the connecting rod 803. One end of the spring 806 is fixedly connected to the inner wall of the groove 801, and the other end of the spring 806 is fixedly connected to the surface of the push plate 804.

[0065] In this embodiment: the push plate 804 and the groove 801 are connected by the spring 806. When the heat sink 903 is removed and the push plate 804 is released, the connecting rod 803 will automatically reset under the action of the spring 806, thereby restoring the spring 902 to its initial state and preventing the spring 902 from being damaged due to the pressure plate 805 stretching the spring 902 for a long time.

[0066] Combining the above solutions:

[0067] Furthermore:

[0068] like Figure 9 As shown;

[0069] In order to improve the strength of the extrusion plate 805, in an optional embodiment, a reinforcing block 807 is fixedly installed between the extrusion plate 805 and the connecting rod 803. There are two sets of reinforcing blocks 807, and the two sets of reinforcing blocks 807 are symmetrically distributed on the surface of the connecting rod 803.

[0070] In this embodiment, two sets of symmetrically distributed reinforcing blocks 807 are installed on the surface of the connecting rod 803, which can improve the support strength of the extrusion plate 805 and prevent the extrusion plate 805 from bending on both sides when the clamping arm of the extrusion spring 902 is extruded, thus affecting normal use.

[0071] Combining the above solutions:

[0072] Furthermore:

[0073] like Figure 3 and Figure 9 As shown;

[0074] In order to facilitate the opening of the clamping arm of the spring sheet 902, in an optional embodiment, the two sides of the extrusion plate 805 are chamfered, and the chamfers are parallel to the inner wall of the spring sheet 902.

[0075] In this embodiment: by opening chamfers on both sides of the extrusion plate 805, and the chamfers are parallel to the inner wall of the spring sheet 902, when the extrusion plate 805 moves, the chamfers on both sides can slide along the inner wall of the spring sheet 902, which facilitates the pushing of the extrusion plate 805 and also improves the opening speed of the spring sheet 902.

[0076] Working principle: When the heat sink 903 needs to be replaced, manually push the push plate 804. The push plate 804 drives the connecting rod 803 to slide within the through slot 802. At the same time, the push plate 804 compresses the spring 806. The connecting rod 803 simultaneously drives the pressing plate 805 to move. At this time, the pressing plate 805 pushes the clamping arm of the spring 902 until the spring 902 is opened. At this time, the heat sink 903 is released from its fixation. The heat sink 903 can be removed from the spring 902. Then, take out the new heat sink 903 and let the locking block 906... Opposite to the slot 905, the heat sink 903 is pushed into the spring 902, and then the push plate 804 is released. Under the action of the spring 806's own elastic force, the spring 806 drives the push plate 804 to move in the opposite direction. The push plate 804 simultaneously drives the connecting rod 803 to move. The connecting rod 803 drives the pressing plate 805 away from the clamping arm of the spring 902 until the spring 806 is completely restored. At this time, the pressing plate 805 also returns to its initial state. At this time, due to the elasticity of the spring 902 itself, its clamping arm can clamp and fix the heat sink 903.

[0077] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
