Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lamp devices, and in particular to a vehicle lamp device capable of switching between high and low beams with dual lenses and a switching method thereof. Background Art

[0002] The automotive lighting system is a core component that ensures nighttime driving safety. Its performance directly affects the driver's field of view and road interaction safety. Traditional headlights mainly rely on the following technical solutions to achieve high and low beam functions: Early vehicles used separate high and low beam groups, which required independent light sources and reflective cavities. This solution has problems such as large size, high power consumption, and abrupt light pattern transitions, and it is unable to achieve adaptive beam control.

[0003] With the development of automotive lighting technology, dual-lens headlights have been widely used because they can integrate high and low beam functions into a single optical system. However, existing technologies still have the following core problems: The mainstream solution relies on electromagnets to drive the movement of sun visors (such as lifting sun visors) to achieve switching between high and low beams. When the low beam is on, the sun visor drops to block part of the light, and when the high beam is on, the sun visor rises to release the light blocking. However, this design has obvious defects. If the lifting sun visor is set inside the headlight, the overall volume of the headlight needs to be designed to be large enough, occupying the space of the vehicle body. If the sun visor partially extends to the outside of the headlight, it is necessary to cut a groove on the top of the headlight, which will make the internal sealing of the headlight worse. Although it does not occupy the internal volume of the headlight, it still occupies the space of the vehicle body, and its use is limited.

[0004] To this end, we provide a high and low beam dual-lens drive switching vehicle lamp device and a switching method thereof to solve the above-mentioned problems. Summary of the Invention

[0005] The object of the present invention is to provide a vehicle lamp device with dual-lens drive switching for high and low beams and a switching method thereof, so as to solve the problem proposed in the above background technology that if the lifting sunshade is set inside the vehicle lamp, the overall volume of the vehicle lamp needs to be designed to be large enough, occupying the vehicle body space; if the sunshade is partially extended to the outside of the vehicle lamp, it is necessary to cut a groove on the top of the vehicle lamp, which will make the internal sealing of the vehicle lamp worse, and although it does not occupy the internal volume of the vehicle lamp, it still occupies the vehicle body space, and has limitations in use.

[0010] The vehicle lamp device with dual-lens drive switching for high and low beams as described above: the first gear mechanism includes a first gear arranged on the second rotating shaft and a second gear arranged on the third rotating shaft, and the first gear is meshed with the second gear.

[0011] As described above, a vehicle lamp device with dual lenses for driving and switching high and low beams: a second motor is provided on the fixing frame, and an output end of the second motor is connected to a third rotating shaft through a coupling to drive the third rotating shaft to rotate.

[0012] As described above, the vehicle lamp device with dual-lens drive switching for high and low beams: the limit clamping assembly includes a limit rod arranged on the fixing frame and a limit hole opened on the adjustment block, and the limit rod is inserted into the limit hole.

[0013] As described above, the vehicle lamp device with dual-lens drive switching for high and low beams: the second gear mechanism includes a third gear arranged on the second rotating rod and a fourth gear arranged on the first rotating rod, and the third gear is meshed with the fourth gear.

[0014] The vehicle lamp device with dual-lens drive switching for high and low beams as described above: a dual-lens is provided at the port of the cover shell, and the dual-lens is made of transparent glass or transparent plastic.

[0015] A method for switching high and low beams of a vehicle lamp device driven by a dual lens for switching high and low beams comprises the following steps: S1, when in use, the sun visor is initially in a horizontal state and closely attached to the top wall inside the cover. When it is necessary to switch to low beam, the second motor is started to drive the third rotating shaft and the second rotating shaft to rotate, thereby driving the first worm and the second worm to rotate. The worm gear is engaged with the first worm and the second worm to drive the worm gear to rotate and move downward at the same time, thereby driving the first rotating rod on the adjustment block to move downward. At the same time, the rotation of the worm gear will drive the second rotating rod to rotate. When the second rotating rod rotates, it will drive the first rotating rod to rotate synchronously, so that when the first rotating rod moves downward, it rotates and drives the sun visor to move downward and flip to a vertical state to block the light emitted by the bulb. At the same time, the first motor is started to drive the first rotating shaft to rotate counterclockwise, driving the bulb to flip counterclockwise, so that the bulb flips from a horizontal state to a downward tilt, thereby switching the headlight to low beam; S2, when it is necessary to switch to high beam, the first motor is started to drive the first rotating shaft to rotate clockwise, driving the light bulb to flip clockwise and reset to a horizontal state. In addition, the second motor is started to drive the third rotating shaft and the second rotating shaft to reverse, thereby driving the first worm and the second worm to rotate in the opposite directions. The worm gear is engaged with the first worm and the second worm to drive the worm gear to rotate and move upward at the same time, thereby driving the first rotating rod on the adjustment block to move upward. At the same time, when the worm gear rotates, it will drive the second rotating rod to rotate. When the second rotating rod rotates, it will drive the first rotating rod to rotate synchronously. Therefore, when the first rotating rod moves upward, it rotates by itself to drive the sunshade to move upward and flip to a horizontal state and stick to the top wall inside the cover. The sunshade no longer blocks the light emitted by the light bulb, thereby switching the headlights to high beam.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When in use, the sunshade is initially in a horizontal state and is tightly attached to the top wall inside the cover. When it is necessary to switch to low beam, the second motor is started to drive the third rotating shaft and the second rotating shaft to rotate, driving the first worm gear and the second worm gear to rotate, and the worm gear is engaged with the first worm gear and the second worm gear to drive the worm gear to rotate and move downward at the same time, thereby driving the first rotating rod on the adjusting block to move downward. At the same time, when the worm gear rotates, it will drive the second rotating rod to rotate. When the second rotating rod rotates, it will drive the first rotating rod to rotate synchronously, so that when the first rotating rod moves downward, its own rotation drives the sunshade to move downward and flip to a vertical state to block the light emitted by the bulb. At the same time, the first motor is started to drive the first rotating shaft to rotate counterclockwise, driving the bulb to flip counterclockwise, so that the bulb flips from a horizontal state to a downward tilt, When the headlight is switched to low beam, when it is necessary to switch to high beam, the first motor is started to drive the first rotating shaft to rotate clockwise, causing the bulb to flip clockwise and reset to a horizontal state. In addition, the second motor is started to drive the third rotating shaft, and the second rotating shaft is reversed, thereby driving the first worm and the second worm to rotate in opposite directions. The worm gear is engaged with the first worm and the second worm to drive the worm gear to rotate and move upward at the same time, thereby driving the first rotating rod on the adjusting block to move upward. At the same time, the rotation of the worm gear drives the second rotating rod to rotate, and the rotation of the second rotating rod drives the first rotating rod to rotate synchronously, so that when the first rotating rod moves upward, its own rotation drives the sunshade to move upward and flip to a horizontal state and stick to the top wall inside the cover. The sunshade no longer blocks the light emitted by the bulb, thereby switching the headlight to high beam. Therefore, the present invention arranges the sun visor inside the cover and the driving mechanism outside the cover. When the light is low beam, the sun visor moves down and gradually flips to a vertical state. When the light is high beam, the sun visor moves up and gradually flips to a horizontal state and fits against the top wall inside the cover for storage. As a result, the structure for switching the sun visor between high and low beams reduces the space occupied inside the headlight and the vehicle body, which is conducive to a lighter overall vehicle body design. In addition, when the light is high beam, the sun visor is stored in the top wall inside the cover, which can reduce the light blocking loss and have a better outward illumination effect. In addition, the number of through grooves adapted to the sun visor on the top of the headlight is reduced, which is conducive to increasing the sealing of the headlight.

[0032] In this embodiment, when it is necessary to switch to low beam, the first motor 4 is started to drive the first rotating shaft 5 to rotate counterclockwise, driving the bulb 2 to flip counterclockwise, so that the bulb 2 flips from a horizontal state to a downward tilt, so that the light of the bulb 2 is more directed to the bottom surface, and then the car light is switched to low beam. When it is necessary to switch to high beam, the first motor 4 is started to drive the first rotating shaft 5 to rotate clockwise, driving the bulb 2 to flip clockwise and reset to a horizontal state, so that the light emitted by the bulb 2 is emitted straight outward, and switching to the high beam state.

[0034] In this embodiment, a reflector is fixedly mounted on one side of the shading plate 7 close to the bulb 2.

[0035] As a further solution of the present invention, the driving mechanism includes a fixed frame 10 arranged on the cover shell 26, and a second rotating shaft 11 and a third rotating shaft 12 are rotatably arranged on the fixed frame 10, and the second rotating shaft 11 and the third rotating shaft 12 are transmitted through a first gear mechanism.

[0036] In this embodiment, when it is necessary to switch between high and low beams, the third rotating shaft 12 is driven to rotate, and the second rotating shaft 11 and the third rotating shaft 12 are transmitted through the first gear mechanism. When the third rotating shaft 12 rotates, it will drive the second rotating shaft 11 to rotate synchronously, and the second rotating shaft 11 and the third rotating shaft 12 rotate in opposite directions. The rotation of the second rotating shaft 11 and the third rotating shaft 12 drives the first worm 23 and the second worm 24 to rotate. The worm wheel 18 is engaged with the first worm 23 and the second worm 24 to drive the worm wheel 18 to rotate and move up and down at the same time, thereby driving the first rotating rod 8 on the adjusting block 16 to move up and down. At the same time, when the worm wheel 18 rotates, it will drive the second rotating rod 17 to rotate. When the second rotating rod 17 rotates, it will drive the first rotating rod 8 to rotate synchronously, so that when the first rotating rod 8 moves up and down, its own rotation drives the shading plate 7 to move up and down and flip to block or release the light emitted by the bulb 2.

[0037] As a further solution of the present invention, the first gear mechanism includes a first gear 14 provided on the second rotating shaft 11 and a second gear 15 provided on the third rotating shaft 12 , and the first gear 14 is meshed with the second gear 15 .

The worm gear 18 is engaged with the first worm 23 and the second worm 24 to drive the worm gear 18 to rotate and move downward, thereby driving the first rotating rod 8 on the adjusting block 16 to move downward. At the same time, when the worm gear 18 rotates, it drives the second rotating rod 17 to rotate. When the second rotating rod 17 rotates, it drives the first rotating rod 8 to rotate synchronously, so that when the first rotating rod 8 moves downward, it rotates and drives the sunshade 7 to move downward and flip to a vertical state to block the light emitted by the bulb 2. At the same time, the first motor 4 is started to drive the first rotating shaft 5 to rotate counterclockwise, driving the bulb 2 to flip counterclockwise, so that the bulb 2 flips from a horizontal state to a downward tilt, thereby switching the headlight to low beam; When it is necessary to switch to high beam, the first motor 4 is started to drive the first rotating shaft 5 to rotate clockwise, driving the bulb 2 to flip clockwise and reset to a horizontal state.

When the second rotating rod 17 rotates, it will drive the first rotating rod 8 to rotate synchronously, so that when the first rotating rod 8 moves upward, it rotates and drives the sunshade 7 to move upward and flip to a horizontal state and stick to the top wall inside the cover 26. The sunshade 7 no longer blocks the light emitted by the bulb 2, thereby switching the car light to high beam.

[0048] The above embodiments are exemplary rather than restrictive, so any technical solution that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.

At the same time, the first motor (4) is started to drive the first rotating shaft (5) to rotate counterclockwise and drive the light bulb (2) to flip counterclockwise, so that the light bulb (2) flips from a horizontal state to a downward tilt, thereby switching the car light to a low beam; S2, when it is necessary to switch to high beam, the first motor (4) is started to drive the first rotating shaft (5) to rotate clockwise, driving the light bulb (2) to flip clockwise and reset to a horizontal state, and the second motor (13) is started to drive the third rotating shaft (12) and the second rotating shaft (11) to reverse, thereby driving the first worm (23) and the second worm (24) to rotate in the opposite direction, and the worm wheel (18) is engaged with the first worm (23) and the second worm (24) to drive the worm wheel (18) to rotate and move upward at the same time, thereby driving the first rotating rod (8) on the adjustment block (16) to move upward, and at the same time, the worm wheel (18) will drive the second rotating rod (17) to rotate when the worm wheel (18) rotates, and the second rotating rod (17) will drive the first rotating rod (8) to rotate synchronously when the second rotating rod (17) rotates, so that when the first rotating rod (8) moves upward, it rotates and drives the shading plate (7) to move upward and flip to a horizontal state and stick to the top wall inside the cover (26), and the shading plate (7) no longer blocks the light emitted by the light bulb (2), thereby switching the headlight to high beam.
