Description

Technical Field

[0001] The invention relates to the field of vehicle headlamp cleaning equipment, and in particular to a vehicle headlamp washing device. Background Art

[0002] When a car is driving, its headlights may be contaminated with dirt, which affects its lighting effect. When the car headlights need to be cleaned, the car headlight washer sprays cleaning fluid on the front perspective mirror of the headlight to clean it, so as to ensure the lighting effect of the car headlights and ensure the safety of car driving.

[0003] Publication number CN101020449B discloses an automotive headlamp washer, primarily comprising a nozzle assembly, a piston, a spring, a base, a water inlet, and a cylinder. The base is provided with an annular groove, which, together with the outer wall of the cylinder, forms a diversion channel. The cylinder has a diversion inlet and a diversion outlet. The piston has a diversion hole communicating with its inner cavity, and a sealing ring and an end cap are installed at the end of the piston extending into the cylinder. The nozzle assembly comprises a nozzle, a diversion cone, and a nozzle, and is in communication with the piston's inner cavity. These features collectively form a cleaning fluid channel. This invention has the advantages of a simple structure, a small number of parts, low manufacturing cost, reliable operation, and excellent cleaning performance.

[0036] To help those skilled in the art better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that the drawings are for illustrative purposes only and are not to be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the dimensions of actual products. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and are not to be construed as limiting this patent.

[0037] Reference Figure 1-10 , the present invention discloses a washing device for a vehicle headlamp.

[0038] For details, please refer to Figure 1-4 :

[0039] The vehicle headlamp 2 comprises a vehicle body panel 1, a base 3, and a mounting plate 4. The vehicle headlamp 2 is mounted on the vehicle body panel 1. When the device is in standby mode, the base 3 and the vehicle body panel 1 form a single unit, preventing aerodynamic impact during vehicle operation. The mounting plate 4 is fixed to one side of the back of the vehicle body panel 1, and a protective cover 9 is fixed to the surface of the mounting plate 4. A rotating mechanism is fixed to the back of the base. A spray mechanism is located on the back of the base and can deliver washing liquid to the base and spray washing liquid along the back of the base. The spray mechanism is connected to the vehicle's windshield water tank and draws water from the windshield water tank to clean the surface of the vehicle headlamp 2 by spraying it. A cleaning mechanism is fixed to the back of the rotating mechanism and can rotate the cleaning mechanism relative to the base, with the cleaning surface of the cleaning mechanism conforming to the outer surface of the vehicle headlamp. An angle adjustment and telescopic mechanism is located on the back of the base and can drive the base and cleaning mechanism into and out of the slot and rotate the base and cleaning mechanism to the vehicle headlamp.

[0040] See Figure 5 , in one embodiment:

[0041] The angle adjustment and telescopic mechanism includes a positioning plate 8, which is fixed to the surface of the mounting plate 4. A first motor 18 is fixed to one side of the positioning plate 8, and a first gear 17 is fixed to the output end of the first motor 18. The first motor 18 is used to drive the first gear 17 to rotate.

[0042] The angle adjustment and telescopic mechanism also includes a first support seat 11 and a rotary telescopic assembly. The rotary telescopic assembly includes a slide 16. The first support seat 11 is fixed to the surface of the mounting plate 4 and is located on one side of the positioning plate 8. A through hole is horizontally opened inside the first support seat 11, and deep groove bearings 12 are installed at both ends of the through hole. The slide 16 is rotatably connected to the inside of the first support seat 11 through the deep groove bearing 12. The deep groove bearing 12 is used to increase the smoothness of the connection between the slide 16 and the first support seat 11, and is also used to limit the slide 16 to prevent the slide 16 from sliding horizontally inside the first support seat 11, thereby increasing the stability of the equipment operation. One end of the slide 16 is fixedly connected to the second gear 19, and the second gear 19 is used to drive the slide 16 to rotate.

[0043] From the above-mentioned mechanism design, it can be seen that when the first motor 18 drives the first gear 17 to rotate, the first gear 17 drives the second gear 19 to rotate, and the second gear 19 drives the slide 16 to rotate, so that the slide 16 drives the rotating telescopic assembly, the cleaning mechanism and the base 3 to rotate, thereby adjusting the angle of the cleaning mechanism and the base 3.

[0044] See Figure 6-7 , in one embodiment:

[0045] The length of the rotating telescopic assembly is adjustable, and it also includes a second motor 20. The second motor 20 is fixed to one end of the inner wall of the slide 16. The output end of the second motor 20 is fixedly connected to a screw rod 22. The surface of the screw rod 22 is connected to a slide column 21 through a threaded rotation. The second motor 20 is slidably connected to the inside of the slide 16.

[0046] From the above-mentioned mechanism design, it can be seen that the second motor 20 rotates to drive the screw rod 22 to rotate. When the screw rod 22 rotates, it drives the slide column 21 to extend and retract inside the slide cylinder 16 through the thread. The rotating mechanism is fixed to the top of the slide column 21. When the slide column 21 moves, it drives the rotating mechanism to move, thereby driving the cleaning mechanism and the base 3 to move.

[0047] The second motor 20 can be fixed to the interior of the slide 16 by means of threads or bolts. The outer surface of the slide 21 is provided with an elongated slot 25 in the same direction as the slide's extension and contraction. A stopper 26 is provided on the side of the inner wall of the slide 16 at a position corresponding to the slot 25. The stopper 26 is slidably connected to the interior of the slot 25. The slot 25 and the stopper 26 are used to limit the position of the slide 21. With the stopper 26 slidably connected to the interior of the slot 25, the screw rod 22 can drive the slide 21 to extend and contract within the interior while preventing the slide 21 from rotating relative to the slide 16. When the slide 16 rotates, it can drive the second motor 20 and the slide 21 to rotate synchronously.

[0048] See Figure 5 and Figure 7 , in one embodiment:

[0049] The rotating mechanism includes a first shell 15 and a second shell 23. The second shell 23 is fixed to the top of the sliding column 21. A third motor 24 is fixed inside the second shell 23. One end of the other side of the first shell 15 is fixedly connected to the second shell 23. One end of the third motor 24 is fixedly connected to a first bevel gear 27. The first bevel gear 27 is located inside the first shell 15. The third motor 24 is used to drive the first bevel gear 27 to rotate.

[0050] See Figure 7-8 , in one embodiment:

[0051] The rotating mechanism also includes a transmission rod 30. Two limit blocks 29 are fixed inside the base 3. The transmission rod 30 is rotatably connected to the inside of the limit block 29. The limit block 29 is used to limit the transmission rod 30, offset the lateral force generated by the transmission rod 30, and make the transmission rod 30 more stable when rotating. One end of the transmission rod 30 is fixed with a second bevel gear 28, and the other end of the transmission rod 30 is fixedly connected to a third bevel gear 31. The second bevel gear 28 is meshed with the first bevel gear 27.

[0052] The other end of the other side of the first shell 15 is internally rotatably connected to the first connecting seat 33, and one end of the first connecting seat 33 is fixedly connected to the fourth bevel gear 32, and the fourth bevel gear 32 is meshed with the third bevel gear 31; the second shell 23 is rotatably connected to the inside of the second support seat 40, and can move along the angle adjustment and telescopic direction of the telescopic mechanism.

[0053] From the above structural design, it can be seen that when the third motor 24 drives the first bevel gear 27 to rotate, since the first bevel gear 27 is engaged with the second bevel gear 28, the first bevel gear 27 drives the second bevel gear 28 to rotate, and then the second bevel gear 28 drives the transmission rod 30 to rotate, and the transmission rod 30 drives the third bevel gear 31 to rotate. Since the third bevel gear 31 is engaged with the fourth bevel gear 32, the third bevel gear 31 drives the fourth bevel gear 32 to rotate, and the fourth bevel gear 32 drives the first connecting seat 33 to rotate. The cleaning mechanism is rotatably connected to the other end of the first connecting seat 33 through a pin, and the axis of the pin is perpendicular to the axis of the first connecting seat 33, driving the cleaning mechanism to rotate when the first connecting seat 33 rotates.

[0054] See Figure 8-10 In one embodiment:

[0055] The cleaning mechanism includes a spring steel plate 34, and a second connecting seat 10 is symmetrically fixed on the back of the spring steel plate 34. The second connecting seat 10 is rotatably connected to the other end of the first connecting seat 33 through a pin. A rubber strip 36 is clamped inside the spring steel plate 34, and a brush 37 is fixed on the side of the rubber strip 36 away from the spring steel plate 34. The second connecting seat 10 is rotatably connected to the first connecting seat 33, so that the angle between the brush 37 and the vehicle headlamp 2 can be compensated, thereby improving the fit between the brush 37 and the vehicle headlamp 2 and improving the cleaning effect of the brush 37 on the surface of the vehicle headlamp 2.

[0056] The cleaning mechanism further comprises a buckle 38 , a barb 14 is symmetrically provided on one side of the buckle 38 , and a square buckle hole 39 is symmetrically provided on one end of the spring steel plate 34 .

[0057] During assembly, the rubber strip 36 is clamped inside the spring steel plate 34 , and the hook 14 is clamped inside the square clamping hole 39 by inserting the buckle 38 into one side of the spring steel plate 34 to prevent the rubber strip 36 from slipping out of the spring steel plate 34 .

[0058] See Figure 4 In one embodiment:

[0059] The liquid spraying mechanism includes a fixed conduit 13 and a second water pipe 7. The fixed conduit 13 is fixed to the back of the base 3. A plurality of water nozzles 35 are fixed to one side of the fixed conduit 13. One end of the second water pipe 7 is fixedly connected to one end of the fixed conduit 13. The other end of the second water pipe 7 is fixedly connected to a self-priming water pump 5. One end of the self-priming water pump 5 is fixedly connected to a first water pipe 6. The first water pipe 6 is connected to the glass water tank of the car.

[0060] As can be seen from the above structural design, the self-priming water pump 5 draws windshield washer water through the first water pipe 6, and the self-priming water pump 5 pumps the windshield washer water into the interior of the fixed guide tube 13 through the second water pipe 7, and sprays the windshield washer water on the surface of the vehicle headlamp 2 through the water nozzle 35. When the brush 37 rotates to clean the surface of the vehicle headlamp 2, the water nozzle 35 sprays windshield washer water onto the surface of the vehicle headlamp 2, which can soften the stains on the surface of the vehicle headlamp 2. The water nozzle 35 can effectively remove stains and dust attached to the surface of the vehicle headlamp 2.

[0061] See Figure 2-4 , in one embodiment:

[0062] During use, the angle adjustment and telescopic mechanism drives the rotating mechanism, the cleaning mechanism and the base 3 to move away from the vehicle body cover 1, and the angle adjustment and telescopic mechanism drives the rotating mechanism, the cleaning mechanism and the base 3 to rotate 90 degrees clockwise, so that the cleaning mechanism reaches the position of the vehicle headlamp 2, and then the rotating and telescopic assembly drives the rotating mechanism, the cleaning mechanism and the base 3 to move in the direction close to the vehicle headlamp 2, so that the cleaning mechanism is close to the surface of the vehicle headlamp 2, and then the rotating mechanism drives the cleaning mechanism to rotate to clean the surface of the vehicle headlamp 2. While the cleaning mechanism rotates to clean, the spray mechanism sprays glass water on the surface of the vehicle headlamp 2, which can effectively remove dust and mud on the surface of the vehicle headlamp 2, thereby avoiding affecting the lighting effect of the vehicle headlamp 2 and ensuring driving safety.
