Description

Technical Field

[0001] This utility model relates to the field of automotive headlight housing technology, specifically an automotive headlight housing structure that is easy to disassemble and replace. Background Technology

[0002] In the assembly and maintenance of automotive headlights, the connection and fixing of the lamp housing and the transparent lens is a critical process, directly affecting the headlight's sealing performance, structural stability, and assembly efficiency. Currently, the industry commonly uses multiple bolts to connect and fix the lamp housing and the transparent lens. This requires workers to use tools to screw each bolt into its corresponding mounting hole, necessitating multiple alignment checks to ensure bolt hole alignment. This cumbersome process, especially in mass production, significantly reduces overall assembly efficiency and increases labor and time costs. Furthermore, during later maintenance or replacement of the lamp housing or transparent lens, the bolts must be removed one by one in reverse, which is also inconvenient and hinders the rapid completion of repair work. Furthermore, due to the structural limitations of bolted connections, the connection between the lamp housing and the transparent lamp cover is prone to forming large gaps due to uneven bolt distribution, force deviation during installation, or insufficient sealing structure design. These gaps not only allow external dust, rainwater, and other impurities to seep into the headlight, affecting the normal operation and lifespan of internal components such as bulbs and reflectors, but may also cause abnormal noises as airflow passes through the gaps during vehicle operation, reducing the user experience. The existing connection structure can no longer meet the automotive industry's requirements for efficient assembly, reliable sealing, and convenient maintenance. Therefore, this utility model provides a car headlight housing structure that is easy to disassemble and replace. Utility Model Content

[0014] 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.

[0015] Please see Figure 1-5 A removable and replaceable automotive headlight housing structure includes a housing 1 and a transparent lamp cover 11. A first annular groove 12 and a second annular groove 13 are formed on one side of the housing 1. Several through holes 121 are formed between the first annular groove 12 and the second annular groove 13. A sealing airbag 14 is installed in the second annular groove 13. A plug ring 15 is installed on one side of the transparent lamp cover 11 and is inserted into the inner wall of the first annular groove 12. When the sealing airbag 14 inflates, it presses against one side of the transparent lamp cover 11. Support plates 2 are installed on both sides of the transparent lamp cover 11. A connecting rod 21 is rotatably connected to one side of each support plate 2. Socket plates 3 are installed on both sides of the housing 1. Each socket plate 3 has a socket hole 31 and a clearance groove 311. A limiting block 22 is installed on one side of the connecting rod 21. The limiting block 22 is slidably connected to the inner wall of the clearance groove 311 and rotatably connected to one end of the socket plate 3.

[0016] It should be noted that a torsion spring is installed between the connecting rod 21 and the support plate 2 as described in this embodiment.

[0017] Specifically, in terms of the connection structure, the support plates 2 on both sides of the transparent lampshade 11 are inserted into the socket holes 31 of the socket plates 3 on both sides of the lamp housing 1 via the rotatable connecting rods 21. The torsion spring between the connecting rods 21 and the support plates 2 drives the limiting block 22 to rotate and lock into the relief groove 311. Fixing and disassembly can be completed quickly without tools, greatly improving assembly and maintenance efficiency. In terms of the sealing structure, the insertion ring 15 of the transparent lampshade 11 is inserted into the first annular groove 12 of the lamp housing 1 for initial positioning. The sealing airbag 14 in the second annular groove 13 expands and squeezes the transparent lampshade 11. At the same time, the through hole 121 balances the air pressure to ensure that the airbag expands evenly, forming a double seal to completely prevent dust and rainwater from seeping in. In terms of structural stability, the symmetrically distributed support plates 2 and socket plates 3 ensure even force distribution. With the elastic preload of the torsion spring, it effectively prevents the connection from loosening due to vibration during vehicle operation. Compared with traditional bolt connections, this structure has significantly improved disassembly and assembly efficiency, sealing reliability, and vibration resistance, meeting the needs of the automotive industry for efficient assembly, reliable sealing, and convenient maintenance.

[0018] In one embodiment of this utility model, such as Figures 1-5 As shown, an annular groove 111 is provided on one side of the transparent lampshade 11, and the sealing airbag 14 is engaged and connected to the inner wall of the annular groove 111.

[0019] Specifically, the annular groove 111 on one side of the transparent lampshade 11 engages with the sealing airbag 14 in the second annular groove 13 of the lamp housing 1. When the sealing airbag 14 expands, it will embed into the inner wall of the annular groove 111, forming a more fitting sealing structure. Through the engagement design of the annular groove 111 and the sealing airbag 14, the airbag can be precisely embedded into the groove after expansion, filling all possible gaps, completely eliminating the infiltration channels of dust and rainwater, and greatly improving the sealing reliability.

[0020] In one embodiment of this utility model, such as Figures 1-5 As shown, the side wall of the connecting rod 21 has a pinch groove 211, which corresponds to the position of the limiting block 22.

[0021] Specifically, the grip groove 211 on the side wall of the connecting rod 21 corresponds to the position of the limiting block 22. During disassembly, the operator can easily grip the connecting rod 21 through the grip groove 211 and apply rotational force to make the limiting block 22 disengage from the limiting state of the relief groove 311, thereby quickly separating the transparent lampshade 11 from the lamp housing 1.

[0022] In one embodiment of this utility model, such as Figures 1-5 As shown, a fixing magnet 32 ​​is installed at one end of the socket plate 3, and a connection notch 221 is opened on one side of the limiting block 22. The fixing magnet 32 ​​is engaged with the inner wall of the connection notch 221, and the fixing magnet 32 ​​and the limiting block 22 are magnetically attracted to each other.

[0023] Specifically, the fixing magnetic block 32 at one end of the socket plate 3 engages with the connection notch 221 on one side of the limiting block 22. At the same time, the fixing magnetic block 32 and the limiting block 22 are magnetically attracted. After the limiting block 22 rotates to the limiting position, the limiting block 22 is firmly fixed to one end of the socket plate 3 by means of the engagement structure and the dual action of magnetic force, preventing it from falling out of the limiting state due to vibration or other factors.

[0024] In one embodiment of this utility model, such as Figures 1-5 As shown, a piston ring 4 is slidably connected to the inner wall of the first annular groove 12, and one end of the insert ring 15 contacts the side wall of the piston ring 4.

[0025] Specifically, when the insert ring 15 of the transparent lampshade 11 is inserted into the first annular groove 12 of the lamp housing 1, one end of the insert ring 15 contacts the piston ring 4 on the inner wall of the first annular groove 12 and pushes it to slide. The piston ring 4 is tightly fitted under the pressure of the insert ring 15, forming a preliminary seal. At the same time, the sliding compensates for the assembly error between the insert ring 15 and the first annular groove 12, ensuring tight contact.

[0026] In one embodiment of this utility model, such as Figures 1-5 As shown, a number of return springs 41 are installed on one side of the piston ring 4, and the return springs 41 are all installed inside the first annular groove 12.

[0027] Specifically, the return spring 41 in the first annular groove 12 is connected to the piston ring 4. When the insert ring 15 of the transparent lamp cover 11 is inserted and pushes the piston ring 4 to slide, the return spring 41 is compressed and generates a reverse elastic force, so that the piston ring 4 always fits tightly against one end of the insert ring 15. After the transparent lamp cover 11 is removed, the return spring 41 extends and pushes the piston ring 4 back to the initial position.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: During assembly, firstly, insert the insertion ring 15 of the transparent lampshade 11 into the first annular groove 12 of the lamp housing 1. One end of the insertion ring 15 contacts and pushes the piston ring 4 on the inner wall of the first annular groove 12 to slide. The piston ring 4 squeezes the return spring 41 in the first annular groove 12. The return spring 41 generates a reverse elastic force to make the piston ring 4 tightly fit the insertion ring 15, forming a preliminary seal and compensating for assembly errors. Next, operate the connecting rod 21 on the support plates 2 on both sides of the transparent lampshade 11 and insert it into the socket holes 31 on both sides of the socket plate 3 of the lamp housing 1. The torsion spring between the connecting rod 21 and the support plate 2 drives the connecting rod 21 to rotate, so that the limiting block 22 slides along the relief groove 311 to one end of the socket plate 3. At this time, the fixing magnet 3 of the socket plate 3... 2. The connecting notch 221 of the limiting block 22 is inserted and magnetically attracted to achieve a stable connection between the transparent lampshade 11 and the lamp housing 1. Then, the sealing airbag 14 in the second annular groove 13 is expanded. The sealing airbag 14 is embedded in the annular groove 111 of the transparent lampshade 11 and squeezes the transparent lampshade 11. The through hole 121 between the first annular groove 12 and the second annular groove 13 balances the air pressure to ensure that the airbag expands evenly and forms a double seal. When disassembling, the connecting rod 21 is rotated by applying force through the pinch groove 211 of the connecting rod 21, so that the limiting block 22 is disengaged from the limiting of the fixed magnetic block 32 and the relief groove 311. The transparent lampshade 11 and the lamp housing 1 can be separated by pulling out the connecting rod 21. At the same time, the return spring 41 pushes the piston ring 4 to return to its original position.
