Description

Technical Field

[0001] This invention relates to the field of lens module technology, specifically to a headlight lens module. Background Technology

[0002] The headlight lens module is a key component for improving the light focus, illumination distance, and uniformity of the light. Its ease of installation, connection stability, and efficiency of later maintenance and replacement directly affect the cost of vehicle manufacturing and after-sales maintenance, as well as the user experience.

[0003] Currently, common headlight lens module installation methods mainly include bolt fixing, clip connection, or adhesive bonding. While bolt fixing provides a secure connection, the installation and removal process is cumbersome, requiring specialized tools, limited operating space, and resulting in low efficiency. Furthermore, it carries the risk of loosening under frequent vibration, increasing maintenance difficulty. Clip connection, while relatively convenient, often suffers from issues such as easily damaged clips, insufficient connection strength, loosening after prolonged use, or difficulty unlocking at certain angles, affecting the optical stability and safety of the lens module. Adhesive bonding, on the other hand, offers virtually no removability; replacing the lens or repairing other components often requires destructive removal, which is costly and environmentally unfriendly.

[0016] This invention provides a headlight lens module. Compared with the prior art, it has the following advantages: 1. This headlight lens module, through the setting of an elastic plate, limiting block, pressure block, round rod, connecting rod, cylinder, seat, compression spring, moving rod, arc plate and stop block, connects the seat and cylinder. The connecting rod and round rod are inserted into the slot. The round rod squeezes the pressure block and elastic plate outward. After being inserted into the interior, the elastic plate gradually returns to its original shape. The pressure block presses down on the round rod, restricting the round rod from moving outward. The compression spring pushes the moving rod and stop block to move. The stop block blocks the limiting block, restricting the elastic plate from bending outward, preventing the pressure block from loosening and causing the cylinder and seat to separate. This makes the lens installation convenient and the connection firm.

[0017] 2. This headlight lens module, through the setting of a plug rod, a stop block, a stop block, a pressure rod, a moving frame, and a push block, connects the cylinder and the base. The cylinder presses against the pressure rod, the pressure rod pushes the moving frame and the push block to move, and the push block pushes the plug rod, causing the locking block and the stop block to separate. Then, the compression spring pushes the moving rod and the stop block to move, the stop block blocks the limit block, and the moving frame and the push block tilt to move. After the plug rod has moved, the push block and the plug rod separate, and the push spring pushes the plug rod back to its original position. This facilitates the separation of the cylinder and the base, making lens replacement convenient.

[0018] 2. The headlight lens module is connected by a blower mechanism, an air guide mechanism, and a ventilation slot. When the blower mechanism is activated, hot air enters the ventilation slot through the air guide mechanism to defog the surface of the lens, facilitating headlight illumination. The connection of the air guide mechanism is sealed to prevent hot air leakage and ensure that hot air passes through the ventilation slot. Attached Figure Description

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

[0022] Please see Figures 1 to 12 This invention provides a technical solution: a headlight lens module, including a lens 1, a fixing seat 2 fixed to the rear end of the lens 1, a mounting seat 3 provided at the rear end of the fixing seat 2, the mounting seat 3 including a seat body 306, a plurality of round rods 302 provided at the front of the seat body 306, connecting rods 303 fixed at both ends of the round rods 302 respectively, the connecting rods 303 and the seat body 306 being fixedly connected, a plurality of arc-shaped plates 304 fixed to the front surface of the seat body 306, a plurality of arc-shaped grooves 308 formed inside the arc-shaped plates 304, a compression spring 307 fixed inside the arc-shaped grooves 308, a moving rod 309 fixed to the other end of the compression spring 307, and the moving rod 309 being fixed to the other end of the compression spring 307. The other end of 09 is fixed with a stop 301. The fixed base 2 includes a cylinder 202. A slot 203 is opened at the rear end of the cylinder 202. Multiple elastic plates 201 are fixed inside the slot 203. Pressure blocks 204 and limiting blocks 206 are fixed on both sides of the elastic plates 201, which facilitates the replacement and installation of the lens 1. Limiting plates 205 are fixed on both sides of the elastic plates 201 inside the slot 203, which can limit the position of the connecting rod 303 and the round rod 302. A rotating ring 305 is rotatably connected to the outer wall of the base 306. The rear end of the stop 301 is fixedly connected to the rotating ring 305, which allows multiple stop blocks 301 to move simultaneously.

[0023] Furthermore, the stop block 301 has a movable groove 320 on the side near the moving rod 309. Inside the movable groove 320 is an insert rod 326. A locking block 310 is fixed to the end of the insert rod 326 away from the movable groove 320. The arc plate 304 has an insertion hole 324 on the end near the moving rod 309. A blocking block 325 is fixed inside the insertion hole 324. A pushing spring 319 is fixed to the rear surface of the insert rod 326. This can limit the stop block 301, facilitating the docking, installation, and removal of the cylinder 202 and the seat 306. A spring hole 318 is opened on the rear surface of the movable groove 320. The other end of the pushing spring 319 is located inside the spring hole 318, allowing the pushing spring 319 to be stored. A positioning rod 321 is slidably connected inside the insert rod 326. Both ends of the positioning rod 321 are fixedly connected to the inner sidewall of the movable groove 320, which can enhance the stability of the positioning rod 321.

[0024] Furthermore, a pressure rod 311 is slidably connected inside the stop block 301. An inclined groove 312 is formed at the end of the movable groove 320 away from the moving rod 309. The side of the inclined groove 312 away from the insertion rod 326 is an inclined surface. A limit rod 315 is fixed inside the inclined groove 312. A moving frame 314 is slidably connected to the outer wall of the limit rod 315. A return spring 322 is fixed inside the moving frame 314. A push block 323 is fixed to the other end of the return spring 322. The limit rod 315 is inclined, so when the cylinder 202 and the seat 306 are connected, the insertion rod 326 can move automatically, thereby separating the locking block 310 and the blocking block 325. A C-shaped rod 313 is slidably connected inside the pressure rod 311. Both ends of 313 are fixedly connected to the movable frame 314, thus connecting the pressure rod 311 and the movable frame 314. A movable magnetic block 316 is fixed to the rear end of the movable frame 314, and a fixed magnetic block 317 is fixed to the inner rear surface of the inclined groove 312. The fixed magnetic block 317 and the movable magnetic block 316 repel each other, and the repulsive force is greater than the elastic force of the return spring 322. Thus, when the push block 323 and the insertion rod 326 separate, and the cylinder 202 and the seat 306 separate, the repulsive force causes the movable frame 314 and the push block 323 to move forward, which is convenient for the next installation. The length of the fixed magnetic block 317 is greater than the length of the movable magnetic block 316, so that the movable magnetic block 316 will not move out of the fixed magnetic block 317 when it tilts and moves, and they can always repel each other.

[0025] Furthermore, the seat 306 has an internal air guiding mechanism 8, which includes multiple fixed tubes 801. The fixed tubes 801 are fixedly connected to the cylinder 202. An insert tube 802 is located inside each fixed tube 801, with the other end of the insert tube 802 passing through and fixedly connected to the seat 306. A compression sealing ring 803 is fixed inside the insert tube 802. An annular movable groove 812 is formed inside the fixed tube 801, and a compression ring 804 is located inside the annular movable groove 812. The interior of the 6 has multiple movable rods 805, which are fixedly connected to the compression ring 804. A pressure ring 806 is fixed to the movable rod 805. A fixing ring 809 is fixed to the outer wall of the insertion tube 802. A compression spring 808 is fixed to the other end of the fixing ring 809, and a push ring 807 is fixed to the other end of the compression spring 808. Multiple ventilation slots 7 are provided inside the cylinder 202. When the seat 306 and the cylinder 202 are connected, the insertion tube 802 is inserted into the fixing tube 801, and the compression spring 808 pushes the push ring. 807 pushes the pressure ring 806, which moves the movable rod 805 and the compression ring 804. The compression ring 804 inserts into the compression sealing ring 803, compressing it. The compression sealing ring 803 expands outward and fits tightly against the outer wall of the insertion tube 802, sealing it. In this way, hot air enters the fixed tube 801 through the insertion tube 802, and then passes through the ventilation slot 7 to dry and defog the lens 1. The compression sealing ring 803 seals the connection between the insertion tube 802 and the fixed tube 801, fixing the lens. A spring groove 810 is provided at one end of the tube 801 near the pressure ring 806. A movable spring 811 is fixed inside the spring groove 810. The other end of the movable spring 811 is fixedly connected to the pressure ring 806. The elastic force of the compression spring 808 is greater than that of the movable spring 811. This allows the compression ring 804, the movable rod 805, and the pressure ring 806 to return to their original positions, and the compression sealing ring 803 no longer expands. This reduces the friction between the compression sealing ring 803 and the insertion tube 802 and extends the life of the compression sealing ring 803.

[0026] Furthermore, an annular tube 4 is fitted on the outer side of the base 306, and the annular tube 4 is fixedly connected to the insertion tube 802. A connecting hose 5 is fixed to the outer wall of the annular tube 4, and a blower mechanism 6 is provided at the other end of the connecting hose 5. The blower mechanism 6 includes a fixed cylinder 601, and the connecting hose 5 is fixedly connected to the fixed cylinder 601. A fixed frame 602 is fixed inside the fixed cylinder 601, and a motor 603 is fixed inside the fixed frame 602. A fan blade 606 is fixed to the output shaft of the motor 603. An electric heating wire 607 is fixed inside the fixed cylinder 601, and an intercepting net 605 is fixed inside the fixed cylinder 601. A filter element 604 is provided inside the fixed cylinder 601 between the motor 603 and the intercepting net 605. When the motor 603 and the electric heating wire 607 are started, the motor 603 rotates the fan blade 606, which generates hot air. The hot air enters the insertion tube 802 to dry and defog the lens 1.

[0027] During operation, first, the rotating ring 305 is rotated, moving the stop block 301 along with it, causing the insertion rod 326 to be inserted into the insertion hole 324. The locking block 310 and the blocking block 325 move in opposite directions. Next, the base 306 and the cylinder 202 are aligned, and the connecting rod 303 and the round rod 302 are inserted into the slot 203. The round rod 302 pushes the pressure block 204 and the elastic plate 201 outward. Once inserted, the elastic plate 201 gradually returns to its original shape, and the pressure block 204... 4. Press down on the round rod 302 to restrict its outward movement. The cylinder 202 and the base 306 are connected. The cylinder 202 presses against the pressure rod 311. The pressure rod 311 pushes the moving frame 314 and the push block 323 to move at an angle. The push block 323 pushes the insert rod 326, causing the locking block 310 and the blocking block 325 to separate. Then, the compression spring 307 pushes the moving rod 309 and the stop block 301 to move. The stop block 301 moves to the limit block 206, blocking... Block 301 blocks the limiting block 206, restricting the elastic plate 201 from bending outwards, preventing insufficient compression of the cylindrical rod 302 by the pressure block 204, which could lead to loosening of the connection between the cylindrical rod 202 and the base 306. This facilitates the installation of the lens 1. The moving frame 314 and the push block 323 move at an angle via the limiting rod 315. When the push block 323 pushes the insertion rod 326, it reduces contact with the insertion rod 326. After the insertion rod 326 has moved completely, the push block... When 323 and the insertion rod 326 are separated, the spring 319 pushes the insertion rod 326 back to its original position. When it needs to be removed, rotate the rotating ring 305 so that the insertion rod 326 is inserted into the insertion hole 324. The locking block 310 and the blocking block 325 move away, and at the same time, the rotating ring 305 moves away from the limiting block 206 with the blocking block 301, no longer blocking the limiting block 206. Pull the cylinder 202 to separate the cylinder 202 from the base 306, making it easy to replace the lens 1. When the seat 306 moves downwards to align with the cylinder 202, the insertion tube 802 fixed to the seat 306 is inserted into the fixed tube 801 fixed to the cylinder 202. The end of the insertion tube 802 first contacts and pushes the compression ring 804 inside the fixed tube 801. The compression ring 804 transmits force to the pressure ring 806 through the movable rod 805 connected to it, forcing the pressure ring 806 to move against the elastic force of the movable spring 811. As the compression ring 804 is pushed into the insertion tube 802, the compression ring 806 moves against the elastic force of the movable spring 811. In the compression sealing ring 803, a radial compression force is generated on the compression sealing ring 803, forcing the soft compression sealing ring 803 to expand radially outward. After expansion, the outer side of the compression sealing ring 803 is tightly fitted with the inner wall of the insertion tube 802, and its inner side is in close contact with the compression ring 804, thereby forming a sealed air duct at the connection between the insertion tube 802 and the fixed tube 801, effectively preventing hot air leakage. When the blower mechanism 6 is started, the motor 603 drives the fan blade 606 to rotate, drawing air into the fixed tube 801. The fixed cylinder 601 draws in air that is filtered by the filter element 604 and heated by the electric heating wire 607, turning it into clean hot air. The hot air is delivered to the annular pipe 4 through the connecting hose 5 for distribution, and then evenly distributed to each insertion tube 802. The hot air flows through the sealed connection, through the fixed pipe 801, and finally blown out from the ventilation slot 7 on the cylinder 202, directly acting on the surface of the lens 1 to achieve the functions of drying and defogging. When the seat 306 separates from the cylinder 202, the external force disappears, and the previously compressed springs begin to release their elasticity. The compression spring 808 pushes the push ring 807 to reset. Subsequently, the elasticity of the movable spring 811 is released, pushing the pressure ring 806 to reset. The pressure ring 806 drives the compression ring 804 to exit from the compression sealing ring 803 through the movable rod 805. Once the compression ring 804 exits, the radial compression force applied to the compression sealing ring 803 disappears, and the sealing ring recovers its original shape by its own elastic contraction, no longer sticking tightly to the inner wall of the insertion tube 802.
