[0031] The present invention will be further described with reference to the accompanying drawings.
[0032] like Figures 1 to 13As shown, an automatic air-drying device for car washing includes an air-drying rack 5, a first lifting device 610, a first flipping device 410, a first rotary blowing device 110, a second lifting device 620, a second flipping device 420 and a second rotary blowing device 120. The air-drying rack 5 is installed on the ground, and the first lifting device 610 is installed at one end of the air-drying rack 5, which is located in the entry direction of the car; the first flipping device 410 is slidably installed on the air-drying rack 5, and the first flipping device 410 is also connected to the first lifting device 610. The first lifting device 610 is used to drive the first flipping device 410 to rise and fall to change the distance between the car and the first rotary blowing device 110; two first rotary blowing devices 110 are provided, and the first rotary blowing devices 110 are installed on the first flipping device 410, and are arranged relative to the front, front windshield, top, rear windshield, trunk and rear of the car. The rotating blowing device 110 is used to swing and blow air toward both sides of the air-drying rack 5, and the first flipping device 410 is used to drive the first rotating blowing device 110 to swing and blow air toward both ends of the air-drying rack 5; the second lifting device 620 is installed at the other end of the air-drying rack 5; the second flipping device 420 is slidably installed on the air-drying rack 5, and the second flipping device 420 is also connected to the second lifting device 620, and the second lifting device 620 is used to drive the second flipping device 420 to lift and lower; the second rotating blowing device 120 is arranged at two, and the second rotating blowing device 120 is symmetrically installed on the second flipping device 420, and is located on both sides of the second flipping device 420, the second rotating blowing device 120 is arranged opposite to the two sides of the car, and is used to swing and blow air toward both sides of the air-drying rack 5, and the second flipping device 420 is used to drive the second rotating blowing device 120 to swing and blow air toward both ends of the air-drying rack 5.
[0033] The first lifting device 610 and the second lifting device 620 are used to drive the first rotary blowing device 110 and the second rotary blowing device 120 to rise and fall, and then adjust the distance between the first rotary blowing device 110 and the second rotary blowing device 120 and the automobile, so that the first rotary blowing device 110 and the second rotary blowing device 120 are close to the automobile to blow air, reduce the damage of wind pressure and air volume, and can effectively improve the air-drying effect.
[0034] The first flip device 410 and the second flip device 420 respectively drive the first rotating blowing device 110 and the second rotating blowing device 120 to swing back and forth. The back and forth swinging can adjust the direction of the air outlet so that the air outlet can face the front, front windshield, top, rear windshield, trunk and rear of the car, or blow at an angle, thereby approaching the problem that the existing blowing devices can only blow in the vertical direction, resulting in the front and rear of the car cannot be dried. Moreover, since blowing directly can accelerate the flow of water on the surface of the car, the drying effect is effectively improved.
[0035] The first rotating blowing device 110 and the second rotating blowing device 120 can swing left and right, thereby causing the wind blowing onto the car to swing left and right, which can push the water on the surface of the car to flow quickly to both sides, effectively improving the air-drying effect.
[0036] The lifting device allows the air outlet to be close to the car, reducing the loss of wind pressure and air volume. The flip device 44 allows the air outlet to face the car to avoid dead angles for blowing air. The rotating air blowing can increase the speed of air drying, which improves the air drying effect as a whole, shortens the air drying time, improves the air drying efficiency, and reduces the cost of air drying.
[0037] In order to improve the use range of the automatic air-drying device for car washing, the automatic air-drying device for car washing also includes a moving device, which is installed at the bottom of the air-drying rack 5 and is used to drive the air-drying rack 5 to move back and forth, so that the car does not move and the automatic air-drying device for car washing moves forward and backward. The moving device includes a driving wheel 52, a driven wheel 51 and a moving motor 53. The driving wheel 52 and the driven wheel 51 are both provided with rolling grooves, and the rolling grooves are movably inserted into the guide rails on the ground. The rolling grooves and the guide rails enable the automatic air-drying device for car washing to move back and forth in a fixed direction. The driving wheel 52 and the driven wheel 51 are respectively installed at the two ends of the bottom of the air-drying rack 5, and the driving wheel 52 is connected to the moving motor 53. The moving motor 53 drives the air-drying rack 5 to move through the driving wheel 52.
[0038] The first rotary blowing device 110 has the same structure as the second rotary blowing device 120. The first rotary blowing device 110 includes: a first motor 22, a rotating device 3, a volute 11 and an impeller 12. The first motor 22 is connected to the volute 11 through the rotating device 3. The volute 11 is provided with an air inlet 111 and an air outlet 112. The impeller 12 is movably located inside the volute 11, and the impeller 12 is arranged opposite to the air inlet 111 and the air outlet 112. The impeller 12 is connected to the first motor 22, and the first motor 22 drives the impeller 12 to rotate to achieve blowing. The rotating device 3 is used to drive the volute 11 to rotate to adjust the air outlet direction of the air outlet 112.
[0039] The first motor 22 is used to drive the impeller 12 to blow air. The impeller 12 is a centrifugal impeller 12. The rotating device 3 is used to drive the volute 11 to rotate, thereby adjusting the air outlet direction of the air outlet 112. The rotating air outlet 112 can cover the vehicle body, and the surface of the vehicle body can be dried by reciprocating the air outlet 112. Since the air outlet 112 is directly arranged on the volute 11, the wind generated by the impeller 12 is directly blown out through the volute 11 and the air outlet 112, the wind pressure loss is small, and the wind pressure and air volume blown to the vehicle body are large, which can not only ensure the air drying effect, but also shorten the air drying time and improve the efficiency of car washing.
[0040] The impeller 12, the volute 11 and the first motor 22 form a centrifugal fan.
[0041] In order to facilitate the installation of the first rotary blowing device 110 and the second rotary blowing device 120 on the first flip device 410 and the second flip device 420, and to facilitate the assembly of the first rotary blowing device 110 and the second rotary blowing device 120, the first rotary blowing device 110 further includes a blowing bottom plate 39, and the first motor 22 and the rotating device 3 are both installed on the blowing bottom plate 39. The blowing bottom plate 39 enables the first rotary blowing device 110 and the second rotary blowing device 120 to form an integral structure, which is convenient for installation.
[0042] In order to facilitate the rotation of the volute 11, the rotating device 3 includes a rotating assembly 310 and a driving assembly 320. The rotating assembly 310 is rotatably arranged on the first motor 22 and connected to the volute 11; the driving assembly 320 is installed on the first motor 22 or the blowing base plate 39, and the driving assembly 320 is also connected to the rotating assembly 310 to drive the rotating assembly 310 to rotate. The rotating assembly 310 realizes the rotation connection between the volute 11 and the first motor 22, and the driving assembly 320 drives the volute 11 to rotate by driving the rotating assembly 310 to adjust the air outlet direction.
[0043] The rotating assembly 310 includes a rotating seat 32 and a rotating ring gear 31. The rotating seat 32 is arranged at the end of the first motor 22 and is coaxial with the motor shaft. The rotating ring gear 31 is movably sleeved on the rotating seat 32. The rotating ring gear 31 can rotate on the rotating seat 32, thereby driving the volute 11 to rotate. The rotating seat 32 facilitates the installation of the rotating ring gear 31.
[0044] In order to prevent the rotating gear ring 31 from moving along the axis, the rotating assembly 310 also includes a fixed retaining ring 321 and a movable retaining ring 33. The fixed retaining ring 321 is arranged at one end of the rotating seat 32. The fixed retaining ring 321 and the rotating seat 32 are an integral structure. The outer diameter of the fixed retaining ring 321 is larger than the outer diameter of the rotating seat 32, but smaller than the outer diameter of the rotating gear ring 31, and is located below the gear teeth of the rotating gear ring 31. The movable retaining ring 33 is fixed to the other end of the rotating seat 32 by screws. The movable retaining ring 33 is arranged opposite to the fixed retaining ring 321. The rotating gear ring 31 is movably located between the fixed retaining ring 321 and the movable retaining ring 33. The fixed retaining ring 321 and the movable retaining ring 33 realize the axial positioning of the rotating gear ring 31, so that the rotating gear ring 31 can only rotate. The movable retaining ring 33 also facilitates the installation of the rotating gear ring 31.
[0045] In order to facilitate the driving of the rotating gear ring 31, the driving assembly 320 includes a driving motor 36 and a driving gear 34. The driving motor 36 is installed on the blowing base plate 39 and is located on one side of the first motor 22. The driving motor 36 is also connected to the driving reducer 35. The output shaft of the driving reducer 35 is connected to the driving gear 34, and the driving gear 34 is meshed with the rotating gear ring 31. The driving motor 36 drives the driving gear 34 to rotate through the driving reducer 35, the driving gear 34 drives the rotating gear ring 31 to rotate, and the rotating gear ring 31 drives the volute 11 to rotate.
[0046] In order to prevent the volute 11 from rotating at an excessive angle, a sliding arc surface 311 is provided on the rotating gear ring 31, and the sliding arc surface 311 is arranged opposite to the driving gear 34. The sliding arc surface 311 is obtained by removing some gear teeth on the rotating gear ring 31. When the sliding arc surface 311 rotates to contact the driving gear 34, the driving gear 34 cannot drive the rotating gear ring 31 to rotate, making the driving gear 34 ineffective, thereby preventing the volute 11 from rotating at an angle exceeding the limit value, and limiting the blowing range of the volute 11.
[0047] In order to accurately control the angle of the air outlet 112 of the volute 11, the first rotating blowing device 110 also includes a blowing angle detection device 330, which is installed on the driving assembly 320 and is used to detect the angle of the air outlet 112 of the volute 11. The blowing angle detection device 330 can detect the real-time angle of the air outlet 112, which is convenient for control. Specifically, the blowing angle detection device 330 includes an angle detection seat 372, an angle detection sensor and an angle detection plate 371. The angle detection seat 372 is installed on the driving reducer 35. The angle detection seat 372 is provided with a first mounting groove 3721 for mounting the angle detection sensor. The first mounting groove 3721 is an arc groove and is coaxially arranged with the output shaft of the driving reducer 35. The arc-shaped first mounting groove 3721 facilitates the installation of the angle detection sensor. A plurality of angle detection sensors can be provided for detecting different positions. The angle detection sensor can adopt a proximity switch or an infrared sensor. The angle detection plate 371 is mounted on the output shaft of the driving reducer 35 and is arranged opposite to the angle detection sensor to enable the angle detection sensor to generate a signal.
[0048] The structure of the first flipping device 410 is the same as that of the second flipping device 420. The first flipping device 410 includes a lifting pulley frame 41, a flipping rod 42, a swing reducer 441 and a swing motor 442. The lifting pulley frame 41 is a U-shaped frame, and both ends of the lifting pulley frame 41 are slidably mounted on both sides of the air-drying rack 5 and connected to the first lifting device 610. The lifting pulley frame 41 can be lifted and lowered in the vertical direction. The swing shaft 443 is symmetrically fixed at both ends of the flip rod 42. The swing shaft 443 at one end of the flip rod 42 is rotatably mounted on one end of the lifting pulley frame 41 through a bearing seat. The swing shaft 443 at the other end of the flip rod 42 is connected to a swing reducer 441. The swing reducer 441 is mounted at the other end of the lifting pulley frame 41 and is connected to a swing motor 442. The swing motor 442 is used to drive the flip rod 42 to rotate through the swing reducer 441, thereby driving the volute 11 to rotate forward and backward, so that the volute 11 can be vertically opposite to the front and rear of the car, ensuring effective air drying of the front and rear of the car, and expanding the blowing range of the air outlet 112 of the volute 11. The flip device 44 has a simple structure and reliable operation.
[0049] The first flipping device 410 and the second flipping device 420 can enable the volute 11 to swing back and forth. The volute 11 that swings back and forth can blow toward the front fender glass and the rear windshield in a forward or tilted state, and blow toward the front, rear, front safe and rear bumper of the car in a forward or tilted state, thereby ensuring that the entire top, front and rear windshields, front and rear can be directly blown by the wind, thereby improving the air-drying effect and solving the problem that the existing air-drying can only blow air in the vertical direction.
[0050] In order to limit the limit position of the volute 11 swinging forward and backward and prevent the volute 11 and the flip rod 42 from forming a 360° rotation, the first flip device 410 also includes a limit assembly 45, which is connected to the flip rod 42 and the lifting pulley frame 41 respectively, and the limit assembly 45 is used to limit the swing angle of the flip rod 42. Specifically, the limit assembly 45 includes a limit seat 451 and a limit rod 453. There are two limit seats 451, which are fixed at one end of the lifting pulley frame 41, and the limit seats 451 are respectively located on both sides of the flip rod 42. The limit rod 453 is fixed at one end of the flip rod 42 and is arranged opposite to the limit seat 451, which is used to limit the limit swing angle of the flip rod 42. Two flip rods 42 can be set as needed. An elastic pad is installed on the limit seat 451, and the elastic pad is arranged opposite to the limit rod 453 to achieve a shock absorbing function. The limit rod 453 is located at one end of the swing reducer 441.
[0051] In order to realize the feedback of the swing angle of the volute 11, the multi-angle air-drying device for car washing further includes a positioning device 48, which is respectively connected to the flip rod 42 and the lifting pulley frame 41, and is used to detect the swing angle of the flip rod 42. By detecting the swing angle of the flip rod 42, the angle of the air outlet 112 of the volute 11 can be obtained, thereby improving the accuracy of controlling the angle of the air outlet 112. Specifically, the positioning device 48 includes a positioning sensor 481, a positioning detection rod 482 and a positioning detection seat 483. The positioning detection rod 482 is fixed at one end of the flip rod 42 away from the swing reducer 441. The positioning detection rod 482 and the positioning detection seat 483 are arranged opposite to each other. The positioning detection seat 483 is fixed at one end of the lifting pulley frame 41. The positioning detection seat 483 is provided with an arc-shaped positioning detection groove 4831. The positioning detection groove 4831 is coaxially arranged with the flip rod 42. The positioning sensor 481 is installed on the positioning detection groove 4831, and multiple positioning sensors can be provided. The positioning sensor 481 is used to detect the positioning detection rod 482, and then obtain the position of the flip rod 42. The positioning sensor 481 can adopt a proximity switch or a photoelectric sensor.
[0052] In order to conveniently control the swing angle of the first flip device 410 and the second flip device 420, so that the first rotating blowing device 110 and the second rotating blowing device 120 can accurately blow air to the front, front windshield, top, rear windshield, trunk and rear of the car, the automatic air-drying device for washing and drying the car also includes a profiling detection device (47), which is arranged on the first flip device 410 and the second flip device 420 and is used to detect the shape of the car body. Specifically, the profiling detection device (47) includes a car body detection frame 471 and a car body detection sensor; the car body detection frame 471 is symmetrically installed at both ends of the bottom of the lifting pulley frame 41, one end of the car body detection frame 471 is provided with a first detection hole 4711 and a second detection hole 4712, and the other end of the car body detection frame 471 is provided with a third detection hole 4713 and a fourth detection hole 4714, and the first detection hole 4711 and the second detection hole 4712 and the third detection hole 4713 and the fourth detection hole 4714 are all arranged up and down. Four vehicle body detection sensors are provided, and the four vehicle body sensors are respectively installed on the first detection hole 4711, the second detection hole 4712, the third detection hole 4713, and the fourth detection hole 4714. The vehicle body sensors on the second detection hole 4712 and the fourth detection hole 4714 are used to detect the vehicle body, while the vehicle body detection sensors on the first detection hole 4711 and the third detection hole 4713 are used to control the lifting height of the first lifting device 610, that is, the vehicle body sensors on the second detection hole 4712 and the fourth detection hole 4714 are in a state of detecting the vehicle body, while the vehicle body detection sensors on the first detection hole 4711 and the third detection hole 4713 are in a state of not being able to detect the vehicle body. The vehicle body sensor adopts a photoelectric opposite-beam sensor, and the vehicle body detection sensor is used to detect the shape of the car, thereby facilitating the control of the first lifting device 610 and the second lifting device 620 and the first flip device 410 and the second flip device 420. When air-drying begins, when both the vehicle body detection sensor on the second detection hole 4712 and the vehicle body detection sensor on the first detection hole 4711 detect the front of the vehicle, the first lifting device 610 drives the first flipping device 410 to rise until the vehicle body detection sensor on the first detection hole 4711 can no longer detect the vehicle body, and the state in which the lower vehicle body detection sensor detects the vehicle body but the upper vehicle body detection sensor can no longer detect the vehicle body is maintained to complete the air-drying of the front, front windshield and top of the car.When air-drying the rear windshield of the car, since the second detection hole 4712 is located above the trunk of the car, the vehicle body detection sensor on the second detection hole 4712 cannot detect the vehicle body. When the vehicle body detection sensor on the fourth detection hole 4714 also cannot detect the vehicle body, the first lifting device 610 drives the first flipping device 410 to descend until the vehicle body detection sensors on the fourth detection hole 4714 and the third detection hole 4713 can detect the vehicle body. Then the first lifting device 610 drives the first flipping device 410 to rise, so that the vehicle body detection sensor on the third detection hole 4713 cannot detect the vehicle body. The state where the vehicle body detection sensor on the fourth detection hole 4714 detects the vehicle body and the vehicle body detection sensor on the third detection hole 4713 cannot detect the vehicle body is maintained, and the drying of the rear windshield, trunk and rear is completed in sequence.
[0053] The first lifting device 610 and the second lifting device 620 have the same structure. The first lifting device 610 includes a lifting bracket 65, a lifting motor 61, a lifting shaft 62, a lifting material roll wheel 63 and a lifting belt 64. The lifting bracket 65 is fixed to the top of the air-drying rack 5 and is connected to the lifting motor 61. The lifting motor 61 is a reduction motor. The lifting motor 61 is connected to the lifting shaft 62. The lifting shaft 62 is installed on the top of the lifting bracket 65 through a plurality of lifting bearing seats. The lifting shaft 62 is also connected to the lifting material roll wheel 63. One end of the lifting belt 64 is fixed in the lifting material roll wheel 63, and the other end of the lifting belt 64 is fixed to the top of the lifting pulley frame 41. When the lifting motor 61 rotates forward, the lifting material roll wheel 63 releases the lifting belt 64, and the lifting belt 64 causes the lifting pulley frame 41 to descend. When the lifting motor 61 rotates reversely, the lifting material roll wheel 63 winds the lifting belt 64, and the lifting belt 64 causes the lifting pulley frame 41 to rise.
[0054] Rollers 411 are provided at both ends of the lifting pulley frame 41, and the rollers 411 are movably inserted into the lifting guide rails 66 on both sides of the air-drying rack 5. The lifting device drives the lifting pulley frame 41 up and down to adjust the distance between the air outlet 112 of the volute 11 and the vehicle body.
