Description

Technical Field

[0001] The present invention relates to the technical field of car washers, and in particular to an unmanned car washer. Background Art

[0002] Against the backdrop of the global automotive industry's intelligent transformation and the penetration rate of new energy vehicles exceeding 40%, unmanned car washes have become an important part of the smart travel ecosystem. New energy vehicle owners are experiencing a surge in demand for efficient, safe, and all-weather car wash services. Traditional manual car washes suffer from low efficiency (average daily service of ≤80 vehicles per station) and insufficient standardization (only 72% pass rate for cleaning), driving unmanned technology to become a focus of industry innovation.

[0003] An unmanned car wash is an automated device used to provide car washing services, usually located in public areas. Car owners can complete the car washing process without interacting with staff. Existing unmanned car washes include tunnel-type car washes, which drive vehicles into the tunnel entrance and then advance them to various washing stages via a conveyor belt or roller system.

[0004] The tunnel-type car washers on the market are usually equipped with a soft-bristle roller brush to physically scrub the car body. When the vehicle passes through the tunnel, the swing bracket will drive the soft-bristle roller brush close to the surface of the car body to remove stubborn stains on the car body. However, due to the different curvatures of the body surfaces of various new energy vehicle models (for example, the door part and the window part on the side of the car body usually have a certain angle, and the surface angles of various models are different), and the soft-bristle roller brush itself is often set perpendicular to the ground, when the soft-bristle roller brush approaches the car body surface, it may not fit well to the side of the new energy vehicle body, especially the window part. Therefore, the existing tunnel-type car washers have the problem of not being able to fit the car body surfaces of different models, resulting in weak scrubbing force in some areas, thereby failing to fully remove stubborn stains or dirt on new energy vehicles;

A deflection motor 37 is fixedly mounted between the first measuring bracket 29 and the second measuring bracket 36. The first measuring bracket 29 and the second measuring bracket 36 are rotatably connected through the deflection motor 37. A spherical joint 33 is installed between the first brush roller 32 and the second brush roller 34.

The transverse motor end plate 30 is fixedly connected to the transverse swing frame plate 24.

[0038] In the above embodiment, it should be noted that the propulsion mechanism is activated to push the transverse swinging frame plate 24 toward the vehicle body until the first measuring bracket 29 contacts the door surface. The first measuring bracket 29 is linked to the first roller brush 32 via the transverse swinging frame plate 24 to move so as to contact the door surface. The locking mechanism is then activated to lock the distance between the transverse swinging frame plate 24 and the transverse deflection bracket 23. The second measuring bracket 36 is then rotated so as to contact the window surface. The second measuring bracket 36 is linked to the second brush roller 34 via the follower swing link 35 to deflect so as to contact the window surface.
