Description

Technical Field

[0001] This utility model relates to the field of car wash machine technology, specifically to a telescopic car wash machine swing arm. Background Technology

[0002] With the popularization of automation technology, tunnel car wash machines have become an important part of modern automotive aftermarket services due to their high efficiency and speed. Traditional tunnel car wash machines are usually equipped with a car wash arm that can move laterally (lateral movement mechanism, such as a crane). Sensors detect the shape of the vehicle and control the car wash arm to move laterally to conform to the surface of the vehicle of different widths and shapes for brushing or spraying, thereby ensuring the cleaning effect.

[0003] However, the presence of a lateral movement mechanism significantly increases the manufacturing cost, structural complexity, and failure rate of car wash machines. To reduce costs and maintenance difficulties, "non-lateral movement" car wash machines have emerged on the market. These car wash machines omit the complex lateral movement mechanism; the wash arms only rotate during the washing process, and the distance between the brushes or spray arms and the car body remains constant.

[0004] However, "non-lateral movement" car wash machines inevitably have the following problems: First, they cannot adapt to the varying widths and body contours of different car models (such as sedans, SUVs, and MPVs). For narrow cars, the wash arm distance is too far, resulting in insufficient brush pressure, increased blind spots, and significantly reduced cleaning effectiveness; for wide cars, the wash arm distance is too close, causing excessive pressure on the brush bristles, which not only accelerates bristle wear but may also pose a risk of scratching the paint. Second, to compensate for the potential inadequate cleaning due to a fixed distance, it is often necessary to increase the power of the water pump and the amount of cleaning agent used, resulting in a waste of water, electricity, and chemicals, leading to serious resource waste. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a telescopic car wash arm, comprising a fixed arm and a movable arm. A drive mechanism enables the movable arm to move, thereby adjusting the distance between the arm and the vehicle body to accommodate vehicles of different widths. This design offers strong applicability, ensures the optimal distance between the arm and the vehicle body, improves cleaning efficiency, and reduces material waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a retractable car wash arm, comprising a drive shaft connected to an external car wash rotation system, a horizontal plate, a drive moving assembly, an anti-scratch and collision structure, a lower fixing member, an upper fixing member, a fixed arm, and a movable arm.

The movable arm is fixedly connected to the side surface of the structure. The movable arm includes a horizontal section and a vertical section. The horizontal section of the movable arm is fixedly connected to one end of the anti-scratch structure. The spraying range of the horizontal section of the movable arm overlaps with the spraying range of the fixed arm. The driving moving assembly includes a motor, a threaded rod, a moving block, and a sliding member. The sliding member is fixedly installed on the lower bottom surface of the horizontal plate. The upper surface of the moving block is fixedly connected to the moving end of the sliding member. The motor is fixedly installed on the side wall of the vertical plate. The output end of the motor is fixedly connected to one end of the threaded rod. The moving block has a threaded hole in the horizontal direction. The threaded rod is screwed into the threaded hole. The lower bottom surface of the moving block is fixedly connected to the side surface of the anti-scratch structure through a lower fixing member.

[0007] Preferably, the sliding component includes a slide rail and a slider. The slide rail is fixedly disposed on the lower bottom surface of the horizontal plate in a horizontal direction, and the slider is slidably disposed on the slide rail. The lower bottom surface of the slider is fixedly connected to the upper surface of the moving block.

[0015] like Figure 1-2As shown, a retractable car wash arm includes a drive shaft 1 connected to an external car wash rotation system, a horizontal plate 4, a drive moving assembly, an anti-scratch structure 14, a lower fixing member 13, an upper fixing member 3, a fixed arm 17, and a movable arm 15. A conductive slip ring 2 is provided on the drive shaft 1. The lower end of the drive shaft 1 is fixedly connected to the horizontal plate 4 via the upper fixing member 3. A vertical plate 5 is fixedly provided on one side of the lower bottom surface of the horizontal plate 4. A first connecting plate 16 is fixedly provided on the vertical plate 5. The fixed arm 17 is horizontally designed and fixedly connected to the first connecting plate 16. The drive moving assembly is disposed on the lower bottom surface of the horizontal plate 4. The upper end of the lower fixing member 13 is fixedly connected to the moving end of the drive moving assembly, and the lower end of the lower fixing member 13 is fixedly connected to the side surface of the anti-scratch structure 14. The movable arm 15 includes a horizontal section and a vertical section. The horizontal section of the movable arm 15 is fixedly connected to one end of the anti-scratch structure. The spraying range of the horizontal section of the movable arm 15 overlaps with the spraying range of the fixed arm 17. The drive moving assembly includes a motor 6, a threaded rod 12, a moving block 11, and a sliding member. The sliding member is fixedly disposed on the horizontal plate 4. The lower bottom surface of plate 4, the upper surface of the movable block 11 is fixedly connected to the moving end of the sliding member, the motor 6 is fixedly mounted on the side wall of the vertical plate 5, the output end of the motor 6 is fixedly connected to one end of the threaded rod 12, the movable block 11 has a threaded hole 7 in the horizontal direction, the threaded rod 12 is screwed into the threaded hole 7, the lower bottom surface of the movable block 11 is fixedly connected to the side surface of the anti-scratching structure 14 through the lower fixing member 13; the sliding member includes a slide rail 9 and a slider 10, the slide rail 9 is fixedly mounted on the lower bottom surface of the horizontal plate 4 in the horizontal direction, and the slider 10 slides. The slider 10 is fixedly connected to the upper surface of the moving block 11 on the slide rail 9. Fixed plates 8 are respectively provided at both ends of the slide rail 9. The two ends of the threaded rod 12 are rotatably mounted on a pair of fixed plates 8 through bearings. One end of the threaded rod 12 passes through the fixed plate 8 and is fixedly connected to the output end of the motor 6. A second connecting plate 18 is fixedly provided on the fixed plate 8 on the side away from the first connecting plate 16. The second connecting plate 18 is fixedly connected to the fixed arm 17. An ultrasonic sensor 19 is fixedly provided on the vertical section of the movable arm 15.

[0016] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows: According to the instruction manual Figure 1-2As can be seen, when this utility model is working, the external car wash rotation system drives the drive shaft 1, the horizontal plate 4, the drive moving component, the anti-scratch structure 14, the fixed arm 17, and the movable arm 15 to rotate, thus cleaning the vehicle. Here, the external car wash rotation system can drive the drive shaft 1 to rotate, and the anti-scratch structure 14 can cut off the power after being scratched during the rotation of the movable arm 15. These are all existing technologies. The wires are connected to the motor 6 through the conductive slip ring 2 to ensure that the wires will not get tangled during operation. In this utility model, the motor 6 drives the threaded rod 12 to rotate. Since the threaded rod 12 is screwed into the threaded hole 7 of the moving block 11, and the moving block 11 is limited by the sliding part, the rotation of the threaded rod 12 can move the moving block 11, thereby driving the lower fixed part 13, the anti-scratch structure 14, and the movable arm 15 to move, adjusting the distance between them and the vehicle body to achieve the purpose of adapting to different width vehicle models. It has strong applicability, ensures the distance between the car wash arm and the vehicle body, improves the cleaning effect, and also reduces material waste. It is important to understand the significance of the fixed arm 17. Without the fixed arm 17, the spraying position would change after the movable arm 15 moves, resulting in some areas at the top not being sprayed. In this invention, the spraying range of the horizontal section of the movable arm 15 overlaps with the spraying range of the fixed arm 17. This is to ensure that the movable arm 15 can move within this overlapping range, thus preventing any areas from being missed.

[0017] The sliding component includes a slide rail 9 and a slider 10. The slide rail 9 is fixedly mounted horizontally on the lower surface of the horizontal plate 4, and the slider 10 is slidably mounted on the slide rail 9. The lower surface of the slider 10 is fixedly connected to the upper surface of the moving block 11. The design of the slider 10 and the slide rail 9 limits the movement of the moving block 11 to ensure its movement in conjunction with the threaded rod 12, and also ensures the stability of the movement of the moving block 11. In this utility model, the driving moving component includes a motor 6, a threaded rod 12, a moving block 11, and a sliding component. The motor 6 drives the threaded rod 12 to rotate, thereby driving the moving block 11, which is limited by the sliding component, to move, and in turn, driving the car wash arm to move. The structure is simple, using common parts, with low cost and easy maintenance. In addition, fixed plates 8 are respectively provided at both ends of the slide rail 9. The two ends of the threaded rod 12 are rotatably mounted on a pair of fixed plates 8 through bearings. One end of the threaded rod 12 passes through the fixed plate 8 and is fixedly connected to the output end of the motor 6. This is to ensure the stability of the threaded rod 12, thereby improving the overall stability.

[0018] A second connecting plate 18 is fixedly installed on the fixed plate 8 on the side away from the first connecting plate 16. The second connecting plate 18 is fixedly connected to the fixed arm 17 to increase the stability of the fixed arm 17.

[0019] Among them, an ultrasonic sensor 19 is fixedly installed on the vertical section of the movable arm 15. The ultrasonic sensor 19 can monitor the distance between the arm and the vehicle body, monitor and adjust the position of the movable arm 15 in real time, and improve the automation level of the car wash machine.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
