Description

Technical Field

[0001] This utility model relates to the field of LED automotive lighting technology, specifically to an LED automotive light that is easy to assemble. Background Technology

[0002] LED automotive lights refer to light sources that use LED technology for both internal and external illumination. External lighting equipment involves thermal limits and EMC issues, as well as many complex standards for unloaded load testing. An LED is an electroluminescent device that uses a solid semiconductor chip as the light-emitting material. It emits light directly by causing photon emission through the recombination of charge carriers. LED automotive lights can be widely used to create the interior environment of a vehicle. They have a lifespan of 50,000 hours. LEDs have a robust structure and are not easily affected by vibration. The light output brightness will not decrease significantly during use.

[0003] Currently, most existing LED automotive lights are assembled using a threaded structure, which requires frequent installation and removal of screws during assembly or disassembly, resulting in relatively low assembly efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an LED automotive light that is easy to assemble and can improve the assembly efficiency of workers, in order to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-assemble LED automotive lamp, comprising a lamp body and LED lamp heads and heat dissipation components respectively installed at both ends of the lamp body, wherein one end of the LED lamp head is provided with a connector, the connector being inserted into the lamp body, and the outer surface of the lamp body is provided with a convex ring, characterized in that: two sets of pressing members are slidably provided on the convex ring, each pressing member having a first linkage member on the side near the lamp body, the first linkage member being linked with a second linkage member, a locking member being slidably provided on the inner surface of the lamp body through a through hole, and a locking groove for the locking member to engage on the outer wall of the connector, wherein the pressing member, through the first linkage member and the second linkage member, can cause the locking member to separate from or engage with the locking groove.

[0006] The above technical solution is adopted in a way that, compared with the existing technology where most LED automotive lights are assembled using a threaded structure, this utility model uses a pressing component to drive the first linkage component to drive the second linkage component, causing the second linkage component to drive the locking component to retract into the first mounting cavity. After the connector is inserted into the lamp body, the locking groove is connected to the through hole. Releasing the pressing component allows the locking component to enter the locking groove and engage, thus completing the installation between the LED lamp head and the lamp body. When disassembly is required, simply pressing the pressing component to disengage the locking component from the locking groove allows the LED lamp head to be removed.

[0007] A further feature of this invention is that the convex ring is provided with a first mounting cavity for mounting a first linkage member, a second linkage member, and a locking member, and a second mounting cavity for sliding mounting a pressing member. The first mounting cavity, the second mounting cavity, and the through hole are all interconnected, and the first linkage member can slide along the first mounting cavity.

[0008] The above technical solution facilitates the assembly of the pressing component, the first linkage component, the second linkage component, and the locking component onto the convex ring by setting the first mounting cavity and the second mounting cavity.

[0009] A further feature of this invention is that: a fixing plate extends downward from the top of the first mounting cavity; the first linkage includes a connecting plate and a first inclined surface located on the side of the connecting plate away from the pressing member; a first elastic member is provided between the fixing plate and the connecting plate; the second linkage includes a second inclined surface abutting against the first inclined surface and a third inclined surface adjacent to the second inclined surface; the first inclined surface can compress the second inclined surface, thereby causing the second linkage to move longitudinally; the third inclined surface is disposed opposite to both sides of the second linkage; a mounting seat is provided on the end of the locking member near the first mounting cavity; a second elastic member is provided between the mounting seat and the fixing plate; and linkage parts that can abut against the third inclined surface are provided at both ends of the mounting seat at the third inclined surface.

[0010] Using the above technical solution: During use, pressing the pressing member inward causes the first linkage member to move inward. At this time, the first elastic member is compressed, and the radial force generated at the contact point between the first and second inclined surfaces causes the second linkage member to move upward. Since the linkage part on the locking member is located on the third inclined surface, as the second linkage member moves, the force generated at the contact point between the third inclined surface and the linkage part causes the locking member to move inward, thereby retracting into the first mounting cavity. At this time, the second elastic member is compressed. Then, the connector is inserted into the lamp body to connect the locking groove with the through hole. Releasing the pressing member resets the first and second elastic members, allowing the locking member to enter the locking groove to achieve engagement and complete the assembly. When disassembly is required, simply pressing the pressing member is sufficient to separate the locking member from the locking groove.

[0011] A further feature of this invention is that: a first spring seat for mounting one end of the first elastic member is provided on one side of the fixing plate near the connecting plate, and a second spring seat for mounting the second elastic member is provided on the other side; a third spring seat for mounting the other end of the first elastic member is provided on the connecting plate; and a sliding groove for moving the second linkage member is provided on the inner wall of the first mounting cavity near the second linkage member.

[0012] The above technical solution facilitates the installation of the first and second elastic elements by setting up the first, second, and third spring seats; at the same time, the sliding groove guides the movement direction of the second linkage element.

[0013] A further feature of this invention is that: the upper part of the connector head is provided with a first sealing groove along its outer wall, the inner wall of the lamp body is provided with a second sealing groove corresponding to the first sealing groove, and a sealing cavity is formed between the first sealing groove and the second sealing groove, and a sealing ring is provided in the sealing cavity.

[0014] The above technical solution facilitates the installation of the sealing ring by creating a sealed cavity. Furthermore, the sealing ring improves the sealing performance at the connection between the lamp body and the LED lamp head, thus enhancing the sealing effect.

[0015] A further feature of this invention is that: a circuit board is provided inside the lamp body, a first wiring terminal is provided on one side of the circuit board, and a second wiring terminal is provided inside the connector of the LED lamp head.

[0016] The above technical solution is adopted: when the connector is inserted into the lamp body, the first terminal and the second terminal will be plugged together to realize the circuit connection of the LED lamp head and ensure that it can emit light.

[0017] A further feature of this invention is that the heat dissipation assembly includes heat dissipation fins fixedly connected to the lamp body and a heat dissipation fan installed on one side of the heat dissipation fins.

[0018] By adopting the above technical solution, the LED automotive lights can be efficiently cooled by the heat dissipation fins and cooling fans, ensuring the performance of the LED automotive lights.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Other structures can be referred to with ordinary design. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of this utility model, they are protected by patent law.

[0029] like Figure 1-7 The LED automotive lamp shown includes a lamp body 1 and LED lamp heads 2 and heat dissipation components 3 respectively installed at both ends of the lamp body 1. One end of the LED lamp head 2 is provided with a connector 21, which is inserted into the lamp body 1. The outer surface of the lamp body 1 is provided with a protruding ring 11, and two sets of pressing members 4 are slidably provided on the protruding ring 11. Each pressing member 4 is provided with a first linkage member 5 on the side near the lamp body 1, and a second linkage member 6 is linked on the first linkage member 5. A locking member 7 is slidably provided on the inner surface of the lamp body 1 through a through hole 113. The outer wall of the connector 21 is provided with a locking groove 211 for the locking member 7 to engage. The pressing member 4 can cause the locking member 7 to separate or engage with the locking groove 211 through the first linkage member 5 and the second linkage member 6.

[0030] like Figure 6-7 The convex ring 11 shown has a first mounting cavity 111 for mounting the first linkage member 5, the second linkage member 6, and the locking member 7, and a second mounting cavity 112 for sliding mounting the pressing member 4. The first mounting cavity 111, the second mounting cavity 112, and the through hole 113 are all interconnected, and the first linkage member 5 can slide along the first mounting cavity 111.

[0031] like Figure 3-6The first mounting cavity 111 shown has a fixing plate 111a extending downward from the top. The first linkage 5 includes a connecting plate 51 and a first inclined surface 52 located on the side of the connecting plate 51 away from the pressing member 4. A first elastic member 511 is provided between the fixing plate 111a and the connecting plate 51. The second linkage 6 includes a second inclined surface 61 abutting against the first inclined surface 52 and a third inclined surface 62 adjacent to the second inclined surface 61. The first inclined surface 52 can squeeze the second inclined surface 61, thereby causing the second linkage 6 to move longitudinally. The third inclined surface 62 is arranged opposite to each other on both sides of the second linkage 6. The locking member 7 has a mounting seat 71 at one end near the first mounting cavity 111. A second elastic member 711 is provided between the mounting seat 71 and the fixing plate 111a. The two ends of the mounting seat 71 are provided with linkage parts 72 that can abut against the third inclined surface 62.

[0032] like Figure 6-7 The fixed plate 111a shown is provided with a first spring seat 111b for mounting one end of the first elastic member 511 on one side near the connecting plate 51, and a second spring seat 111c for mounting the second elastic member 711 on the other side. The connecting plate 51 is provided with a third spring seat 512 for mounting the other end of the first elastic member 511. The first mounting cavity 111 is provided with a sliding groove 111d for moving the second linkage member 6 on the inner wall near the second linkage member 6.

[0033] like Figure 2 The connector 21 shown has a first sealing groove 212 along its outer wall on the upper part, and a second sealing groove 12 corresponding to the first sealing groove 212 is provided on the inner wall of the lamp body 1. A sealing cavity is formed between the first sealing groove 212 and the second sealing groove 12, and a sealing ring 22 is provided in the sealing cavity.

[0034] like Figure 5 The lamp body 1 shown has a circuit board 13 inside, and a first terminal 14 is provided on one side of the circuit board 13. The LED lamp head 2 is located inside the connector 21 and has a second terminal 213. The heat dissipation assembly 3 includes a heat dissipation fin 31 fixedly connected to the lamp body 1 and a heat dissipation fan (not shown in the figure) installed on one side of the heat dissipation fin 31.

[0035] In use, pressing the pressing member 4 inward causes the first linkage member 5 to move inward, compressing the first elastic member 511. The radial force generated at the contact point between the first inclined surface 52 and the second inclined surface 61 causes the second linkage member 6 to move upward. Since the linkage part 72 on the locking member 7 is located on the third inclined surface 62, as the second linkage member 6 moves, the force generated at the contact point between the third inclined surface 62 and the linkage part 72 causes the locking member 7 to move inward, thus retracting into the first mounting cavity 111. At this time, the second elastic member 711 is compressed. Then, the connector 21 is inserted into the lamp body 1, so that the locking groove 211 connects to the through hole 113. Releasing the pressing member 4 resets the first elastic member 511 and the second elastic member 711, allowing the locking member 7 to enter the locking groove 211 to achieve engagement and complete the assembly. When disassembly is required, simply pressing the pressing member 4 causes the locking member 7 to separate from the locking groove 211.
