Description

Technical Field

[0001] This utility model relates to the field of car wash technology, specifically to a brush mechanism applied to a car wash machine. Background Technology

[0002] In the car wash industry, car wash machines are widely used due to their high efficiency and convenience. The middle brush mechanism, a key component of the car wash machine, is primarily responsible for cleaning specific areas of the vehicle, such as the side skirts and headlights.

[0003] Currently, most car wash machines on the market use vertically or horizontally installed brush mechanisms. However, vehicle side skirts typically have curves and indentations, and headlights also have complex curved surfaces. Vertically or horizontally installed brush mechanisms often struggle to achieve proper contact with the vehicle surface when cleaning these areas, resulting in incomplete cleaning and leaving blind spots. Some car wash machines have increased the complexity of the brush mechanism's movement trajectory to improve cleaning results, but this not only increases manufacturing costs but also raises the probability of malfunctions, hindering equipment maintenance and widespread adoption. Utility Model Content

[0004] The purpose of this invention is to provide a brush mechanism for use in car wash machines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a middle brush mechanism applied to a car wash machine, comprising:

[0006] Mounting base, swing arm, telescopic drive mechanism, tilting mounting base, brush body mechanism;

[0007] Wherein, one end of the swing arm is rotatably connected to the mounting base via a rotating shaft, the inclined mounting base is fixedly installed at the other end of the swing arm in an inclined manner, and the brush body mechanism is installed at the bottom of the inclined mounting base;

[0008] The two ends of the telescopic drive mechanism are rotatably connected to the side wall of the swing arm and the mounting base respectively via pins.

[0009] Preferably, the telescopic drive mechanism is a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0010] Preferably, the brush body mechanism includes a brush shaft, which is rotatably connected to an inclined mounting base via a bearing. The inclined mounting base is equipped with a drive mechanism for driving the brush shaft to rotate, and the outer wall of the brush shaft is provided with bristles.

[0011] Preferably, the angle between the axis of the brush shaft and the vertical direction is 8°-12°.

[0012] Preferably, the bottom end of the brush shaft is no more than 150mm from the ground.

[0013] Preferably, the drive mechanism includes a drive motor and a worm gear drive pair. The drive motor is mounted on the side of the inclined mounting base. The worm gear drive pair includes a matching worm wheel and a worm. The worm is connected to the output shaft of the drive motor. The worm wheel is mounted on the upper end of the outer wall of the brush shaft. The worm meshes with the worm wheel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The tilted mounting base, brush shaft, and brush bristles, compared to vertical mounting, allow the tilted bristles to conform obliquely to the curved surface of the headlight and the corners of the skirt when rotating.

[0016] During the car wash process, the telescopic drive mechanism drives the swing arm to rotate and swing appropriately. Due to the inclined structure of the inclined mounting base, when the bristles come into contact with the vehicle's headlights and sides, the bristles undergo a certain elastic deformation as the brush arm rotates and swings, further enhancing the adhesion between the bristles and the vehicle surface, thereby achieving better washing performance and improving the car wash effect.
