Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle lights, and more specifically, to a sealing structure for electric vehicle lights. Background Technology
[0002] With the rapid development of technology, various types of electric vehicles have emerged on the market to facilitate public travel. Riders often require electric vehicle lights for illumination at night, making these lights a core component for ensuring nighttime driving safety. Their sealing performance directly affects the reliability and lifespan of the lighting. Existing electric vehicle light sealing structures mostly employ threaded connections or snap-fit seals between the lampshade and housing, aiming to isolate them from external environmental interference such as rain, dust, and moisture. Traditional threaded connections rely on a single rubber ring; under frequent vibrations, such as when an electric vehicle is bumpy, the threaded gap can easily widen, allowing moisture to seep in. Furthermore, existing lampshades are often fixed at a single point using threads or snaps; the high-frequency vibrations during electric vehicle operation can easily cause the threads to unravel, reducing the fixing effect and increasing the gap between the lampshade and housing, thus diminishing the sealing effect. Additionally, some structures rely on bolts for auxiliary fixation, but installation requires tightening multiple bolts individually, making installation and disassembly inconvenient. Moreover, bolts are prone to corrosion in humid environments, and stripping may occur during disassembly and maintenance, preventing proper lampshade removal. How to improve these problems has become a pressing issue for those skilled in the art. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a sealing structure for electric vehicle lights. It aims to improve upon existing electric vehicle light sealing structures that often employ threaded connections or snap-fit seals between the lampshade and housing. These designs aim to isolate the light from external environmental interference such as rain, dust, and moisture. Traditional threaded connections rely on a single rubber ring, which can easily widen during frequent vibrations, such as when an electric vehicle is bumpy, allowing moisture to seep in. Furthermore, existing lampshades are often fixed at a single point using threads or snaps; the high-frequency vibrations during electric vehicle operation can easily cause the threads to unravel, reducing the fixing effect and increasing the gap between the lampshade and housing, thus diminishing the sealing performance. Additionally, some structures rely on bolts for auxiliary fixing, but this requires tightening multiple bolts individually, making installation and disassembly inconvenient. Moreover, bolts are prone to corrosion in humid environments, and stripping can occur during disassembly and maintenance, preventing the lampshade from being properly disassembled.
[0004] This utility model is implemented as follows: an electric vehicle headlight sealing structure includes a mounting shell and a protective lamp cover. The mounting shell contains a circuit board and LED beads. A connecting shell is installed on one side of the mounting shell. The outer wall of the connecting shell is provided with external threads and a sealing strip. The inner wall of the protective lamp cover is provided with internal threads to cooperate with the external threads. A reinforcement mechanism is installed on the upper end of the connecting shell to cooperate with the protective lamp cover.
[0005] In a preferred embodiment of this utility model, a sealing groove is provided on the inner wall of the protective lamp cover near the connecting shell. A second sealing strip is provided on the inner wall of the sealing groove in conjunction with the sealing strip. The protective lamp cover is initially connected by the internal thread and the external thread of the connecting shell. The second sealing strip completes the sealing between the protective lamp cover, the connecting shell, and the mounting shell by cooperating with the sealing strip, preventing moisture from entering. A mounting base is provided on one side of the mounting shell and it is mounted on the electric vehicle frame.
[0006] In a preferred embodiment of this utility model, the reinforcement mechanism includes a mounting box, which is mounted on the upper end of the connecting shell. A lead screw is rotatably mounted inside the mounting box, and a movable plate is threaded onto the lead screw. A clearance groove is provided on one side of the mounting box in conjunction with the movable plate, and a reinforcement block is mounted on one side of the movable plate. A reinforcement groove is provided on the outside of the protective lampshade in conjunction with the reinforcement block. The reinforcement groove is located on the shell outside the sealing groove. The rotation of the lead screw causes the movable plate to move the reinforcement block within the clearance groove, while simultaneously allowing the reinforcement block to fix the protective lampshade in conjunction with the reinforcement groove of the protective lampshade, preventing the protective lampshade from rotating in the opposite direction, which would reduce installation stability and reduce sealing performance, allowing moisture to enter the device.
[0007] In a preferred embodiment of this utility model, an auxiliary block is installed on one side of the movable plate, and an auxiliary groove is provided inside the mounting box to cooperate with the auxiliary block, which is used to improve the stability of the movable plate and the reinforcing block when they move.
[0008] In the preferred embodiment of this utility model, a rod is rotatably mounted inside the mounting box, a worm is fixedly mounted at one end of the rod, and a worm wheel is fixedly sleeved on the outside of the lead screw. The worm wheel and the worm are meshed together. Rotation of the rod causes the worm to drive the worm wheel to rotate, which in turn causes the lead screw to rotate. At the same time, the self-locking property of the worm prevents the lead screw from rotating in the opposite direction, which would affect the stability of the device reinforcement. This improves the stability and safety of the installation. In addition, the installation and disassembly operations are relatively simple, requiring no bolts for fixation, which saves time in the installation and disassembly process.
[0009] In a preferred embodiment of this utility model, the rod rotates through one side of the mounting box, and an external support is installed at one end of the rod.
[0010] In a preferred embodiment of this utility model, an mounting plate is installed on one inner wall of the protective lampshade, and a light-transmitting cover is installed on the inner wall of the mounting plate.
[0011] In a preferred embodiment of this invention, the sealing strip is arranged in an arc shape near the external thread to facilitate the installation of the protective lampshade.
[0012] The beneficial effects of this utility model are as follows: The electric vehicle headlight sealing structure obtained by the above design allows for initial connection of the protective headlight cover during installation. The protective headlight cover is initially connected via its internal thread engaging with the external thread of the connecting shell. A second sealing strip, in conjunction with the sealing strip, seals the protective headlight cover, connecting shell, and mounting shell, preventing moisture ingress. Rotating the rod via the external support causes the worm gear to rotate, which in turn rotates the lead screw. This rotation of the lead screw causes the moving plate to move the reinforcing block within the clearance groove. Simultaneously, the reinforcing block engages with the reinforcing groove of the protective headlight cover to fix it in place, preventing reverse rotation. The protective headlight cover can be disassembled by manually rotating the external support in the opposite direction. This device achieves an initial threaded connection between the protective headlight cover and the connecting shell, and further reinforces the protective headlight cover through the reinforcing mechanism. The fixing effect is good, and installation and disassembly are convenient and quick, saving time. Attached Figure Description

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] Please see Figures 1-4 The present invention provides a technical solution: a sealing structure for an electric vehicle headlight, comprising a mounting shell 100 and a protective lamp cover 400. The mounting shell 100 is provided with a circuit board 110 and a lamp bead 111. A connecting shell 200 is installed on one side of the mounting shell 100. The outer wall of the connecting shell 200 is provided with an external thread 210 and a sealing strip 220. The inner wall of the protective lamp cover 400 is provided with an internal thread 401 to cooperate with the external thread 210. A reinforcing mechanism 300 is installed on the upper end of the connecting shell 200 in conjunction with the protective lamp cover 400.
[0018] In some specific implementations, a sealing groove 402 is provided on the inner wall of the protective lamp cover 400 near the connecting shell 200. A second sealing strip 430 is provided on the inner wall of the sealing groove 402 in conjunction with the sealing strip 220. The protective lamp cover 400 is initially connected to the connecting shell 200 by the internal thread 401 and the external thread 210. The second sealing strip 430 completes the sealing between the protective lamp cover 400, the connecting shell 200 and the mounting shell 100 by cooperating with the sealing strip 220, so as to prevent moisture from entering. A mounting seat is provided on one side of the mounting shell 100 and it is mounted on the electric vehicle frame.
[0019] In some specific implementations, the reinforcement mechanism 300 includes a mounting box 310, which is mounted on the upper end of the connecting shell 200. A lead screw 320 is rotatably mounted inside the mounting box 310, and a movable plate 330 is threaded onto the lead screw 320. A clearance groove 311 is provided on one side of the mounting box 310 in conjunction with the movable plate 330. A reinforcement block 350 is mounted on one side of the movable plate 330. A reinforcement groove 403 is provided on the outside of the protective lamp cover 400 in conjunction with the reinforcement block 350. The reinforcement groove 403 is located on the shell outside the sealing groove 402. The rotation of the lead screw 320 causes the movable plate 330 to move the reinforcement block 350 within the clearance groove 311. At the same time, the reinforcement block 350, in conjunction with the reinforcement groove 403 of the protective lamp cover 400, fixes the protective lamp cover 400, preventing the protective lamp cover 400 from rotating in the opposite direction, which would lead to a decrease in installation stability, a decrease in sealing performance, and the entry of moisture into the device.
[0020] In some specific implementations, an auxiliary block 340 is installed on one side of the movable plate 330, and an auxiliary groove is provided inside the mounting box 310 to cooperate with the auxiliary block 340, which is used to improve the stability of the movable plate 330 and the reinforcing block 350 when they move.
[0021] In some specific implementations, a rod 380 is rotatably mounted inside the mounting box 310, and a worm 390 is fixedly mounted at one end of the rod 380. A worm wheel 370 is fixedly sleeved on the outside of the lead screw 320. The worm wheel 370 and the worm 390 are meshed. The rotation of the rod 380 causes the worm 390 to drive the worm wheel 370 to rotate, which in turn causes the lead screw 320 to rotate. At the same time, the self-locking property of the worm 390 prevents the lead screw 320 from rotating in the opposite direction, which would affect the stability of the device reinforcement. This improves the stability and safety of the installation. In addition, the installation and disassembly operations are relatively simple, requiring no bolts for fixation, which saves time in the installation and disassembly work.
[0022] In some specific implementations, the rod 380 rotates through one side of the mounting box 310, and an external support 381 is installed at one end of the rod 380.
[0023] In some specific implementations, a mounting plate 410 is installed on the inner wall of one side of the protective lampshade 400, and a light-transmitting cover 420 is installed on the inner wall of the mounting plate 410.
[0024] In some specific implementations, the sealing strip 220 is arc-shaped near the external thread 210 to facilitate the installation of the protective lamp cover 400.
[0025] Working principle: During use, when installing the protective lamp cover 400, the protective lamp cover 400 is initially connected by the internal thread 401 and the external thread 210 of the connecting shell 200. The second sealing strip 430, in conjunction with the sealing strip 220, completes the sealing between the protective lamp cover 400, the connecting shell 200, and the mounting shell 100, preventing moisture from entering. By rotating the rod 380 through the external holder 381, the worm gear 390 drives the worm wheel 370 to rotate, causing the lead screw 320 to rotate. The rotation of the lead screw 320 causes the moving plate 330 to move the reinforcing block 350 within the clearance groove 311. At the same time, the reinforcing block 350, in conjunction with the reinforcing groove 403 of the protective lamp cover 400, fixes the protective lamp cover 400, preventing reverse rotation. The operator can manually rotate the external holder 381 in the reverse direction to disassemble the protective lamp cover 400.
[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
