Description

Technical Field

[0001] This utility model relates to a waterproof and dustproof housing structure for vehicle lights, specifically a waterproof and dustproof housing structure with dual lenses for switching between high and low beams. Background Technology

[0002] Automotive headlights are lighting devices installed at the front of a car to illuminate the road and indicate the vehicle's position at night or in low-light conditions. They consist of a lamp housing, lens, bulb (light source), etc., and mainly include headlights, fog lights, and dome lights. Headlights are further divided into high beams and low beams. Their main function is to provide sufficient road lighting to ensure that the driver can see the road conditions clearly at night or in bad weather conditions.

[0003] Currently, there are two main types of principles for switching between high and low beam headlights in automobiles: one is through mechanical adjustment of the light shield, where the light shield inside the headlight is raised, lowered, or rotated under the drive of a dimmer motor. When using low beam, it blocks the upper part of the light source to form an anti-glare beam, and when using high beam, it avoids the light to release all the light. The other is through independent control of the light source. Some models are equipped with independent low and high beam light sources, and the switching is directly controlled by the circuit to turn the corresponding light source on and off. The core reason for using the light shield method is that it allows a single light source to meet the needs of both low and high beams at the same time, without the need to set up an additional independent high beam light source, which simplifies the headlight structure and reduces costs and space occupation.

[0004] Existing headlight structures that use a raised and lowered sunshade to switch between high and low beams require a slot at the bottom of the headlight housing to accommodate the sunshade's movement. However, when the sunshade lowers to switch to high beam, this slot is completely exposed. This causes light to leak out of the headlight, disrupting the original beam shape and illumination range. This not only reduces the actual high beam efficiency but may also interfere with the vision of surrounding vehicles or pedestrians, posing a safety hazard. Furthermore, the exposed slot loses its protective function, becoming a direct channel for external impurities such as dust, rain, and fog to enter the headlight. These impurities, adhering to the reflector, lens, or light source surface, severely weaken the brightness and light transmission. Additionally, attempting to fix the slot to avoid these problems would conflict with the sunshade's raising and lowering action. The fixed structure would prevent the sunshade from rising and resetting normally to switch back to low beam, causing the high / low beam switching function to fail. Therefore, it is impossible to balance structural protection and functional implementation. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof and dustproof housing structure with dual-lens high and low beam switching to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waterproof and dustproof housing structure with dual-lens high / low beam switching includes a base and a headlight housing fixed to the top of the base. A slot is formed in the middle section of the headlight housing. A shielding ring for covering the slot is slidably mounted on the outer wall of the headlight housing. A light-shielding plate for high / low beam switching is slidably fitted onto the slot of the headlight housing. A support plate and a shaft are mounted on the top of the base. A tilting mechanism that moves with the light-shielding plate is rotatably mounted on the shaft. The tilting mechanism cooperates with a traction component rotatably mounted on the support plate. The traction component is connected to the shielding ring. An adjustment mechanism for raising and lowering the light-shielding plate is mounted on the top of the base.

[0008] The waterproof and dustproof housing structure with dual-lens high and low beam switching as described above: The deflection mechanism includes a deflection plate rotatably mounted on the shaft and a sliding block slidably mounted in the deflection plate. A connecting piece is rotatably connected to the upper part of the sliding block, and the connecting piece is slidably connected to the connecting seat connected to the bottom of the light shield.

[0009] The waterproof and dustproof housing structure with dual-lens high and low beam switching as described above: the deflection mechanism also includes an elastic contraction member connected between the support plate and the deflection plate. The support plate is equipped with a first limiting block and a second limiting block, which respectively limit the two positions of the deflection plate.

[0010] The waterproof and dustproof housing structure with dual-lens high and low beam switching as described above: the traction assembly includes a deflector rotatably mounted on the bottom of the support plate, and the deflector is in a pressing fit with the deflector plate.

[0011] The waterproof and dustproof housing structure with dual-lens high and low beam switching as described above: the traction assembly also includes a connecting arm connected to one side of the shield ring and a sliding groove formed at the bottom of the connecting arm, and one end of the deflector is slidably mounted on the sliding groove.

[0012] The waterproof and dustproof housing structure with dual-lens high and low beam switching as described above: a cylinder is rotatably installed inside the support plate and a connecting rod is slidably installed inside the cylinder. A spring for elastic extension and retraction of the connecting rod is installed inside the cylinder. The connecting rod is rotatably connected to one end of the deflector.

[0013] The waterproof and dustproof housing structure with dual-lens high / low beam switching as described above: The adjustment mechanism includes a drive motor mounted on the top of the base and a screw mounted on the output shaft of the drive motor, with the light shield threadedly connected to the screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By installing a shielding ring on the outside of the headlight housing, when the light shield is inside the headlight housing, the slot is closed by the shielding ring, preventing light leakage and enhancing waterproof and dustproof performance. When the light shield is lowered to switch to high beam, the shielding ring quickly moves to cover the slot to prevent light leakage and block dust and moisture intrusion. When the light shield is raised to switch to low beam, the shielding ring quickly retracts, ensuring smooth raising and lowering of the light shield without affecting its normal operation. This structure effectively solves the problems of light leakage and waterproof and dustproof issues caused by the traditional light shield lifting mechanism for switching between high and low beams.

[0016] The dynamic avoidance design of the visor ring of this utility model does not affect the normal lifting and lowering of the visor to achieve high and low beam switching, and does not require major modifications to the original structure of the headlight housing. It takes into account both structural practicality and operational convenience, and is suitable for various dual-lens headlights that adopt the principle of lifting and lowering the visor for switching, and has broad application prospects.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Please see Figures 1-13 As an embodiment of this utility model, the dual-lens high / low beam switching waterproof and dustproof housing structure includes a base 1 and a headlight housing 2 fixed on the top of the base 1. A slot 3 is provided in the middle section of the headlight housing 2. A shielding ring 4 for covering the slot 3 is slidably installed on the outer wall of the headlight housing 2. A light shield 5 for switching between high and low beams is slidably fitted on the slot 3 of the headlight housing 2. A support plate 6 and a shaft 7 are installed on the top of the base 1. A swing mechanism that moves and cooperates with the light shield 5 is rotatably installed on the shaft 7. The swing mechanism cooperates with a traction component rotatably installed on the support plate 6. The traction component is connected to the shielding ring 4. An adjustment mechanism for raising and lowering the light shield 5 is installed on the top of the base 1.

[0033] In this embodiment, the structure has a slot 3 corresponding to the outer side of the headlight housing 2. A linkage shield ring 4 is arranged at the slot 3. When the light shield 5 is in the low beam state inside the headlight housing 2, the bottom slot 3 is naturally closed. When the light shield 5 is driven to descend by the adjustment mechanism to switch to high beam, the sway mechanism will sway downward as the light shield 5 descends. Then, the sway mechanism will deflect the traction component to one side. After the light shield 5 descends to the bottom, the traction component will pull the shield ring 4, which will simultaneously drive the shield ring 4 to move quickly above the slot 3, achieving immediate coverage of the slot 3, effectively blocking the light leakage path and forming a sealed protection, improving waterproof and dustproof capabilities. When the light shield 5 rises back to switch back to low beam, the traction component will elastically return to its original position, so that the shield ring 4 will quickly withdraw from the slot 3 area, avoiding interference with the lifting and lowering action of the light shield 5, and ensuring a smooth and reliable high beam switching process.

[0034] As a further embodiment of this utility model, the deflection mechanism includes a deflection plate 8 rotatably mounted on the shaft 7 and a sliding block 9 slidably mounted in the deflection plate 8. A connecting member 11 is rotatably connected to the upper part of the sliding block 9, and the connecting member 11 is slidably connected to the connecting seat 10 connected to the bottom of the light shield 5.

[0035] In this embodiment, the shaft 7 is the rotation center shaft of the deflection plate 8, the sliding block 9 is slidably installed on the inner side of the deflection plate 8, the sliding block 9 and the connecting member 11 are rotatably connected, and the connecting member 11 can slide up and down in the connecting seat 10.

[0036] As a further embodiment of this utility model, the swaying mechanism further includes an elastic contraction member 12 connected between the support plate 6 and the deflection plate 8. The support plate 6 is equipped with a first limiting block 13 and a second limiting block 14, which respectively limit the two orientations of the deflection plate 8.

[0037] In this embodiment, the elastic contraction member 12 can apply an elastic tension to the deflection plate 8, which forces the deflection plate 8 to deflect to both sides. The first limiting block 13 and the second limiting block 14 can limit the deflection angle of the deflection plate 8. The first limiting block 13 allows the deflection plate 8 to deflect at a larger angle, while the second limiting block 14 only allows the deflection plate 8 to deflect at a small angle. This allows the deflection plate 8 to swing at a larger angle when deflecting upward, and conversely, to swing at a relatively smaller angle when deflecting downward.

[0038] As a further embodiment of this utility model, the traction assembly includes a deflector 15 rotatably mounted on the bottom of the support plate 6, and the deflector 15 is in a pressing fit with the deflector plate 8.

[0039] In this embodiment, the deflection plate 8 is rotatably mounted on the bottom of the deflection member 15, and a central rotation shaft is also mounted together with the deflection plate 8, and the deflection plate 8 rotates around the central rotation shaft.

[0040] As a further embodiment of this utility model, the traction assembly also includes a connecting arm 16 connected to one side of the shield ring 4 and a sliding groove 17 formed at the bottom of the connecting arm 16, with one end of the deflector 15 slidably mounted on the sliding groove 17.

[0041] In this embodiment, a connecting arm 16 is connected to one end of the bottom of the shielding ring 4, and a sliding groove 17 is provided at the bottom of the connecting arm 16. The end of the deflection plate 8 can be slidably mounted on the sliding groove 17.

[0042] As a further embodiment of this utility model, a cylinder 18 and a connecting rod 19 are rotatably installed inside the support plate 6. A spring 20 for elastically extending and retracting the connecting rod 19 is installed inside the cylinder 18. The connecting rod 19 is rotatably connected to one end of the deflector 15.

[0043] In this embodiment, a cylinder 18 is rotatably mounted on the inner side of the support plate 6, and a connecting rod 19 is slidably mounted inside the cylinder 18. The spring 20 extends the connecting rod 19 outward through elastic force.

[0044] As a further embodiment of this utility model, the adjustment mechanism includes a drive motor 21 mounted on the top of the base 1 and a screw 22 mounted on the output shaft of the drive motor 21, with the light shield 5 threadedly connected to the screw 22.

[0045] In this embodiment, when switching between high and low beams is required, the drive motor 21 drives the screw 22 to rotate. The rotation of the screw 22 will cause the light shield 5 to rise and fall. During the switching of high beams, the light shield 5 moves down, which will cause the deflection plate 8 to deflect downward. At this time, the elastic contraction member 12 will be stretched continuously. When the deflection plate 8 deflects to be in a straight line with the support plate 6, the stretch of the elastic contraction member 12 is at its maximum. At this time, the light shield 5 is completely removed from the slot 3, but the light shield 5 will still move down a little distance. After the deflection plate 8 deflects down by only a little angle, the elastic contraction member 12 will quickly pull back to make the deflection plate 8 quickly deflect to the position of the second limit block 14. At the same time, the deflection member 15 is pressed to one side after it is in contact with the deflection plate 8. At this time, the end of the deflection plate 8 will move diagonally upward. At this time, the connecting rod 19 moves synchronously. The spring 20 will be compressed. At this time, the end of the deflection plate 8 will drive the shield ring 4 to move above the slot 3 for immediate coverage, effectively blocking the light leakage path and forming a sealed protection.

[0046] When the light shield 5 is raised, the deflector plate 8 swings upward. Then, just as the light shield 5 is about to move onto the slot 3, the deflector plate 8 deflects to be flush with the support plate 6. When the deflector 15 is not compressed, the elastic force of the spring 20 will quickly and elastically return the connecting rod 19 to its original position. At this time, the connecting rod 19 pulls the deflector plate 8 to deflect back to its original position, driving the connecting arm 16 and the shield ring 4 to move to one side and away from the slot 3. This allows the shield ring 4 to quickly withdraw from the slot 3 area, avoiding interference with the raising and lowering action of the light shield 5 and ensuring a smooth and reliable high and low beam switching process.

[0047] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
