Description

Technical Field

[0001] This utility model relates to the field of car wash machine technology, and in particular to a swing-type vehicle drying device. Background Technology

[0002] The drying device in a car wash machine is a core functional module of automated car wash equipment. Currently, most car wash machine drying devices on the market use fixed or lifting fans to dry the water stains on the vehicle's exterior surface after washing. Traditional fixed fans have a single angle and are less effective at removing water stains from the vehicle's exterior surface; lifting fans are more effective, but their structure is more complex and the cost is higher. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of existing technologies, such as fixed fans having a single blowing angle and poor drying effect, and lifting fans having a complex structure and high cost and maintenance. The invention provides a swing-type vehicle drying device that controls the fan assembly to swing and blow air along the direction of oncoming vehicle through a drive mechanism and a limit mechanism, driving water stains on the vehicle surface toward the rear of the vehicle. It has a good drying effect and a simple structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a swing-type vehicle drying device, comprising: a gantry frame composed of side columns and a top crossbeam, and a fan assembly fixed to the top crossbeam, characterized in that the top crossbeam is rotatably supported on the top of the side columns, and the drying device further comprises a drive mechanism fixed to the side columns for driving the top crossbeam to rotate and a limiting mechanism for limiting the rotation angle of the top crossbeam, the limiting mechanism having a limiting member for resisting the top crossbeam and limiting the rotation angle of the top crossbeam.

[0005] Furthermore, the limiting member includes a first limiting block located on the side of the top crossbeam shaft in the direction of travel. The first limiting block has a first limiting surface for abutting against the lower surface of the top crossbeam, and the first limiting surface is parallel to the horizontal plane.

[0006] Furthermore, the limiting member also includes a second limiting block located on the side of the top crossbeam pivot in the vehicle departure direction. The second limiting block has a second limiting surface for abutting against the lower surface of the top crossbeam, and the second limiting surface forms an angle with the horizontal plane.

[0007] Furthermore, the angle between the second limiting surface and the horizontal plane is 30°.

[0008] In the technical solution described in this utility model, the fan assembly is restricted to swing within the angle formed by the first limiting surface and the second limiting surface. At the same time, the angle between the second limiting surface and the horizontal plane is set to 30°, so that the swing angle range of the fan assembly is 0°~30°, that is, the extreme position is the vertical downward direction, and the rotation of 30° from the vertical downward direction to the oncoming vehicle direction. This can effectively drive the surface water stains to the rear of the vehicle and the lower part of the vehicle body during the swinging process.

[0009] Furthermore, the driving mechanism includes: a first mounting base fixedly disposed on the side column, a driving component rotatably connected to the first mounting base, and a connecting component rotatably connected to the output end of the driving component and fixedly disposed on the lower surface of the top crossbeam.

[0010] Furthermore, the connector has a downwardly extending extension, the end of which is rotatably connected to the output end of the drive component. The purpose of this downward extension is to increase the driving arm of the drive component, allowing it to rotate the top crossbeam with less force, thereby causing the fan assembly to oscillate and reducing the possibility of damage to the drive component.

[0011] The beneficial effects of this utility model are as follows: The swing-type vehicle drying device of this utility model has a simple structure and strong practicality. The fan assembly is controlled to swing and blow air along the direction of the oncoming vehicle through the drive mechanism and the limiting mechanism. During the swinging process, the fan assembly drives water stains on the vehicle surface towards the rear and lower part of the vehicle body, resulting in good drying effect. At the same time, the first and second limiting surfaces of the limiting mechanism restrict the blowing angle of the fan assembly, allowing the airflow to effectively cover the vehicle surface, reducing dead zones, and improving the water stain removal effect, thus enhancing drying efficiency.

[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please refer to Figure 1 , Figure 2 As shown, this embodiment of a swing-type vehicle drying device includes: side columns 2, top crossbeam 1, fan assembly 3, drive mechanism 4, and limiting mechanism 5. The top crossbeam 1 is rotatably supported at the top of the side columns 2, forming a gantry frame for vehicle entry and exit. Bearings 15 are installed on the pivots at both ends of the top crossbeam 1, and the bearings 15 are mounted on bearing seats, which are bolted to the top of the side columns 2. The fan assembly 3 is fixedly mounted on the lower surface of the top crossbeam 1. The fan assembly 3 includes two fans 17 symmetrically arranged on the lower surface of the top crossbeam 1 and an air duct 18 connecting the two fans and guiding the airflow vertically downwards. The air outlet of the air duct 18 is a strip-shaped opening with a length of 2000mm and a width of 50mm. The drive mechanism 4 is fixed to the upper part of the right side column 2 to drive the top crossbeam 1 to rotate, and the limiting mechanism 5 is fixed to the upper part of the left side column 2 to limit the rotation angle of the top crossbeam 1.

[0022] Please refer to Figure 3As shown, the drive mechanism 4 includes a first mounting base 11, a drive component 12, and a connecting component 13. The first mounting base 11 is fixedly mounted on the upper inner side of the side column 2 by bolts. The bottom end of the drive component 12 is rotatably connected to the first mounting base 11. The connecting component 13 is rotatably connected to the output end of the drive component 12 and fixedly connected to the lower surface of the top crossbeam 1 by bolts. The connecting component 13 has a downwardly extending extension 14, the end of which is rotatably connected to the output end of the drive component 12. The downwardly extending extension of the connecting component increases the driving arm of the drive component, allowing the drive component to drive the top crossbeam to rotate with a smaller force, thereby causing the fan assembly to swing and reducing the possibility of damage to the drive component. In this embodiment, the drive component 12 is a cylinder. In another embodiment, it can also be a servo electric cylinder, which converts the rotary motion of the servo motor into linear motion through a ball screw and can flexibly adjust the stroke range. The swing angle of the top crossbeam 1 is controlled by the stroke of the servo electric cylinder. In another embodiment, the drive mechanism 4 can also be a crank-rocker mechanism, with the drive component 12 being a crank and the connecting component 13 being a connecting rod. The drive component 12 (crank) is rotatably connected to the side column 2 and is driven by a motor to perform circular motion. The drive component 12 is rotatably connected to the connecting component 13, which is rotatably connected to one side of the top crossbeam 1's rotating shaft. The distance from the rotation center of the connecting component 13 (connecting rod) to the center of the top crossbeam 1's rotating shaft is the rocker arm. The distance from the rotation center of the connecting component 13 (connecting rod) to the center of the top crossbeam 1's rotating shaft is the length of the rocker arm. The distance from the rotation center of the drive component 12 (crank) to the center of the top crossbeam 1's rotating shaft is the frame. Under the premise of satisfying the rod length condition, the swing angle of the top crossbeam 1 can be controlled by changing the length of the drive component 12 (crank) or the connecting component 13 (connecting rod).

[0023] Please refer to Figure 4As shown, the limiting mechanism 5 has a limiting member 6 for abutting against the top crossbeam 1 and limiting the rotation angle of the top crossbeam 1, and a second mounting base 16 fixedly installed on the inner side of the side column 2 and fixedly connected to the limiting member 6 by bolts. In this embodiment, the limiting member 6 includes: a first limiting block 7 located on the side of the top crossbeam 1 shaft in the direction of oncoming traffic and a second limiting block 9 located on the side of the top crossbeam 1 shaft in the direction of vehicle departure. The first limiting block 7 and the second limiting block 9 are rubber blocks. The first limiting block 7 has a first limiting surface 8 for abutting against the lower surface of the top crossbeam 1, and the first limiting surface 8 is parallel to the horizontal plane. The second limiting block 9 has a second limiting surface 10 for abutting against the lower surface of the top crossbeam 1, and the second limiting surface 10 forms an angle with the horizontal plane. The angle between the second limiting surface 10 and the horizontal plane is 30°. In this embodiment, the top crossbeam 1 is restricted to swing within the angle formed by the first limiting surface 8 and the second limiting surface 10. Simultaneously, the angle between the second limiting surface 10 and the horizontal plane is set to 30°, allowing the top crossbeam 1 and the fan assembly 3 to swing within a range of 0° to 30°. Specifically, the extreme swing position of the fan assembly 3 is vertically downward, and it can rotate 30° from the vertically downward direction towards the oncoming vehicle. This swing angle allows the airflow to effectively cover the vehicle surface, reducing dead zones and driving surface water stains towards the rear and lower part of the vehicle body during the swing process, improving drying efficiency. In another embodiment, the swing of the top crossbeam 1 and the fan assembly 3 within the range of 0° to 30° can be achieved solely by the first limiting surface 8 or the second limiting surface 10. The position of one extreme angle (0° or 30°) is limited by the first limiting surface 8 or the second limiting surface 10, while the position of the other extreme angle is controlled by the initial position of the cylinder stroke.

[0024] Please refer to Figure 5 , Figure 6 As shown, the specific working principle and process of this embodiment are as follows: The vehicle enters the drying device in the direction indicated by the arrow. Once the photoelectric switch detects the vehicle's entry, the blower assembly 3 starts blowing air. Simultaneously, the drive mechanism 4 controls the pneumatic solenoid valve to drive the cylinder in a reciprocating motion, thereby causing the top crossbeam 1 and the blower assembly 3 to sway. The limiting mechanism 5 restricts the swaying of the top crossbeam 1 and the blower assembly 3 within a range of 0° to 30°. That is, the blower assembly 3 can sway downwards and towards the oncoming vehicle within a 30° range for blowing air, or blow air at a fixed angle. Through testing, in this embodiment, the water-repelling effect is best when the blower assembly 3 forms a 30° angle with the vertical direction, effectively driving water stains from the vehicle surface towards the rear of the vehicle.

[0025] As the vehicle drives under the pillar, the fan assembly 3 oscillates and drives the water stains on the vehicle surface toward the rear and lower part of the vehicle body. As the vehicle continues to move forward, the water stains are driven away from the vehicle surface.
