[0026] The present invention will be further described with reference to the accompanying drawings.

[0027] like Figures 1 to 10 As shown, a pneumatically controlled universal side brush device comprises a car wash frame 1, a left pneumatic assembly 2, a right pneumatic assembly 3, a universal assembly 4, a drive assembly 5 and a large side brush 6. The left pneumatic assembly 2 and the right pneumatic assembly 3 are respectively fixed on both sides of the top of the car wash frame 1, and are staggered front and back. The right pneumatic assembly 3 is located in front of the left pneumatic assembly 2; the universal assembly 4 is respectively installed on the left pneumatic assembly 2 and the right pneumatic assembly 3, and is connected to the drive assembly 5; the drive assembly 5 is connected to the large side brush 6.

[0028] The two large side brushes 6 arranged in an interlaced manner can clean the front and rear of the vehicle respectively, avoiding the interference of the two large side brushes 6. The large side brush 6 on the left air pressure assembly 2 at the rear first contacts the front of the vehicle and is located at a position slightly to the right of the center of the front of the vehicle. The large side brush 6 on the left air pressure assembly 2 starts cleaning from the position slightly to the right of the center of the front of the vehicle, and then gradually moves to the left side of the front of the vehicle until it moves to the left side of the vehicle. Then the front of the vehicle touches the large side brush 6 of the right air pressure assembly 3. The large side brush 6 of the right air pressure assembly 3 is located at a position slightly to the left of the center of the vehicle. The large side brush 6 starts cleaning from the position slightly to the left of the center of the front of the vehicle until it moves to the right side of the vehicle. When cleaning the rear of the vehicle, the large side brush 6 on the left air pressure assembly 2 moves from the left side of the vehicle to the middle position of the rear of the vehicle until it moves to the right position of the center of the rear of the vehicle, completing the cleaning of the left side of the rear of the vehicle. Then the large side brush 6 on the right air pressure assembly 3 moves from the right side of the vehicle to the middle position of the rear of the vehicle until it moves to the left position of the center of the rear of the vehicle, completing the cleaning of the right side of the rear of the vehicle. The two large side brushes 6 arranged in an interlaced manner front and back will not interfere with each other, thus ensuring the cleaning effect of the front and rear of the vehicle.

[0029] The universal assembly 4 can realize the swinging of the large side brush 6 at any angle, which solves the problem that the large side brush 6 cannot swing at an angle when cleaning the front and rear of the vehicle, thereby resulting in insufficient fit with the front and rear of the vehicle and causing poor cleaning effect, thereby improving the cleaning effect of the front and rear of the vehicle.

[0030] The left pneumatic assembly 2 is symmetrical with the right pneumatic assembly 3. The left pneumatic assembly 2 includes a left pressure rod 22 and a left pressure cylinder 23. One end of the left pressure rod 22 is rotatably mounted on the top of the car wash frame 1 through a bearing seat, and the other end of the left pressure rod 22 is connected to the universal assembly 4. The tail of the left pressure cylinder 23 is rotatably mounted on the left side of the top of the car wash frame 1, and the end of the piston rod of the left pressure cylinder 23 is rotatably connected to the middle of the left pressure rod 22 through a fisheye joint. The left pressure cylinder 23 increases the force of the large side brush 6 pressing on the car. Since the gas inside the cylinder can also be compressed, the elastic compression of the large side brush 6 can be achieved, avoiding various problems caused by excessive pressure, and improving safety and reliability.

[0031] In order to improve stability and reliability, the left pneumatic assembly 2 also includes a raceway 26 and a roller 25. The raceway 26 is fan-shaped and fixed to the top of the car wash frame 1. The roller 25 is installed at the bottom of the left pressure rod 22 and movably rests on the raceway 26. The roller 25 and the raceway 26 are used to support the left pressure rod 22, and the roller 25 is installed near one end of the universal assembly 4 of the left pressure rod 22 to reduce the force arm of the left pressure rod 22 and avoid deformation of the left pressure rod 22.

[0032] In order to limit the movement range of the large side brush 6, the left pneumatic assembly 2 also includes a positioning member 24, which is fixed at both ends of the raceway 26. The positioning member 24 is also located on both sides of the left pressure rod 22 to limit the movement limit position of the left pressure rod 22.

[0033] like Figures 4 to 10 As shown, the universal joint assembly 4 includes an upper connecting seat 41, an elastic assembly 42 and a lower connecting seat 43 which are arranged in sequence from top to bottom, wherein an upper connecting flange 411 is provided on the upper connecting seat 41, and a lower connecting flange 431 is provided on the lower connecting seat 43, and the lower connecting flange 431 is located below the upper connecting flange 411 and is arranged opposite to each other; both ends of the elastic assembly 42 are respectively connected to the upper connecting flange 411 and the lower connecting flange 431.

[0034] When there is only one elastic component 42, the elastic component 42 is coaxially arranged with the upper connecting flange 411 and the lower connecting flange 431; when there are at least three elastic components 42, the elastic components 42 are arranged in a circular array along the axis of the upper connecting flange 411. The number of elastic components 42 is set as needed, and can usually be set to 6 to 10.

[0035] The elastic component 42 realizes an elastic connection between the upper connecting seat 41 and the lower connecting seat 43, thereby being able to realize angle adjustment in any direction and compression in any direction. In particular, when the large side brush 6 switches between the side and the front and rear of the car, it can clean the corners of the car very well, and when cleaning the front and rear of the car, it can also provide good compression force and angle adaptability, thereby improving the cleaning effect.

[0036] The elastic component 42 includes a connecting piece 422 and an elastic piece 421. The two ends of the connecting piece 422 are respectively connected to the upper connecting flange 411 and the lower connecting flange 431; the elastic piece 421 is arranged on the connecting piece 422, and the two ends are respectively against the upper connecting flange 411 and the lower connecting flange 431. The elastic piece 421 can be a spring or a rubber column. When a rubber column is used, the rubber column and the connecting piece 422 are an integral structure, and the two ends of the rubber column are respectively against the upper connecting flange 411 and the lower connecting flange 431. The connecting piece 422 usually adopts a screw rod, and the connecting piece 422 is fixed to the upper connecting flange 411 and the lower connecting flange 431 by a nut. When the elastic piece 421 adopts a spring, the spring is movably sleeved on the connecting piece 422, and the two ends of the spring are respectively against the upper connecting flange 411 and the lower connecting flange 431. The elastic piece 421 can also adopt other materials with specific elasticity.

[0037] In order to control the swing angle of the large side brush 6, the large side brush 6 is limited, and also includes a limiter 43. The limiter 44 is arranged on the upper connecting flange 411, and is movably sleeved on the lower connecting flange 431. The limiter 43 is used to limit the swing angle of the lower connecting flange 431, thereby limiting the swing angle of the large side brush 6. Further, the limiter 44 includes an upper limit plate 441, a limit connecting plate 442 and a lower limit plate 443 connected in sequence from top to bottom. The upper limit plate 441 and the lower limit plate 443 are arranged opposite to each other, and both are fan-shaped. The limit connecting plate 442 is arranged along the outer circumferential surface of the lower limit plate 443 and the upper limit plate 441. In order to facilitate observation and processing, the limit connecting plates 442 are arranged in an array, and the top and bottom of the limit connecting plates 442 are welded to the outer circumferential surfaces of the upper limit plate 441 and the lower limit plate 443, respectively. The limiting member 43 forms a limiting sleeve structure, and the upper limiting plate 441 is provided with a plurality of screw holes so as to be fixed on the upper connecting flange 411 of the upper connecting seat 41. The lower limiting plate 443 is movably located below the lower connecting flange 431. When the lower connecting flange 431 is subjected to force, the lower connecting flange 431 will rotate until the edge of the lower connecting flange 431 abuts against the lower limiting plate 443. The lower limiting plate 443 limits the rotation angle of the lower connecting flange 431, thereby realizing the limitation of the swinging angle of the large side brush 6, thereby preventing the swinging angle from being too large, avoiding interference between the large side brush 6 and other components, and avoiding the swinging angle from being too large resulting in a reduction in the contact area with the side, front and rear of the car, thereby ensuring the cleaning effect.

[0038] For the convenience of installation, two limiting members 43 are symmetrically provided, and are installed from both sides of the upper connecting flange 411 during installation.

[0039] For easy installation, an upper connecting column 412 and an upper fixing seat 413 are further provided on the top of the upper connecting seat 41. The upper fixing seat 413 is used to be installed on the end of the left pressure rod 22, and the upper connecting column 412 is used to connect the upper fixing seat 413 and the upper connecting flange 411. The upper connecting column 412, the upper fixing seat 413 and the upper connecting flange 411 can be an integral structure.

[0040] In order to facilitate the installation of the driving assembly 5 of the large side brush 6, the lower connecting seat 43 also includes a fixing flange 432, and the fixing flange 432 is connected to the lower connecting flange 431 through a lower connecting column 433.

[0041] The driving assembly 5 includes a motor and a reducer. The motor is mounted on the reducer. The reducer is mounted on the fixing flange 432 by screws. The output shaft of the reducer is connected to the shaft of the large side brush 6.
