[0002] With the continuous advancement of science and technology, window cleaning robots have been widely used in the work of wiping windows, which is somewhat dangerous. A window cleaning robot is a professional equipment used to clean the exterior window glass of high-rise buildings, also known as a window cleaning machine or a window cleaning machine. It usually includes parts such as the machine body, a window cleaning device, a control system, and a safety device. Window cleaning machines are generally assisted by a base station to perform outdoor window cleaning operations. The base station plays a key role in the field of window cleaning machines. The base station usually includes a battery, a winding structure, a suction cup assembly, etc. The power cord is usually used to connect the window cleaning machine and the base station, wherein one end of the power cord is connected to the window cleaning machine, and the other end of the power cord is connected to the winding structure of the base station.

[0003] However, the power cord generally has a certain length. When the power cord is wound onto the winding structure, it is easy for the power cord to get stuck, knotted, or entangled when entering the winding structure inside the base station, requiring manual untangling, resulting in inconvenience in operation and uneven arrangement on the winding structure.

[0029] See also Figures 1 to 3, an embodiment of the present application provides a wire-winding structure 400 and a window-wiping base station 100 having the same. The wire-winding structure 400 is used in conjunction with a winding structure 200 so that the winding structure 200 can wind a rope, and the winding structure 200 is arranged in a base station housing 110, and a placement hole 111 is provided on the surface of the base station housing 110. The rope can be connected to the winding structure 200 through the placement hole 111. In this embodiment, the rope is a power cord 120, and in other embodiments, the rope can also be a safety rope, which is not limited here and can be selected according to actual conditions. It can be understood that the power cord 120 has a certain strength, so it can also serve as a safety rope.

[0030] See also Figures 2 to 4 The wire-winding structure 400 includes a wire-winding housing 410 and a rolling element 420 connected to the wire-winding housing 410 .

[0031] See also Figures 2 to 4 The wire-winding housing 410 is disposed at the placement hole 111 and connected to the base station housing 110. The wire-winding housing 410 is provided with a wire-passing hole 414 which is connected to the interior of the base station housing 110 and for the rope to pass through. The hole wall of the wire-passing hole 414 is provided with a positioning cavity 415 which is connected to the wire-passing hole 414. A plurality of positioning cavities 415 are arranged at circumferential intervals around the wire-passing hole 414 or the power cord 120.

[0032] The rolling element 420 is rotatably disposed in each positioning cavity 415, and the rolling element 420 is partially exposed and can abut and squeeze the rope. It can be understood that the rolling elements 420 are arranged around the circumference of the rope, and squeeze the side surface of the power cord 120 along the circumference of the power cord 120. When the rope slides through the wire hole 414, each rolling element 420 rotates around itself driven by the rope, and squeezes and reels the rope.

[0033] See also Figures 2 to 4 It can be understood that when the power cord 120 is pulled and wound by the winding structure 200, there is a rolling friction between the power cord 120 and each rolling element 420, so that the power cord 120 can pass smoothly between the rolling elements 420 without getting stuck. At the same time, since each rolling element 420 squeezes the power cord 120, the rolling of each rolling element 420 itself can straighten the knotted parts or bent parts on the power cord 120, or correct and straighten the power cord 120, so that the power cord 120 can be arranged in a row and wound on the winding structure 200, thereby improving the convenience of use.

[0034] See also Figures 2 to 4It can be understood that the rolling element 420 can rotate around the fixed axis in the positioning cavity 415, and the rotation axes of each rolling element 420 can be parallel or non-parallel, so that the power cord 120 can pass smoothly between the rolling elements 420; each rolling element 420 can also rotate freely around itself in the positioning cavity 415. There is no limitation here and it can be selected according to actual conditions.

[0035] It can be understood that the wire-drawing housing 410 can be detachably connected to the base station housing 110 by screws. The screw connection not only simplifies the structure and process, but also improves the convenience of installation and removal of the wire-drawing housing 410.

[0036] In some embodiments, the rolling element 420 is in a spherical shape.

[0037] See also Figures 2 to 4 Optionally, the shape of the inner wall of the positioning cavity 415 is adapted to the shape of the outer surface of the rolling element 420, and the inner wall of the positioning cavity 415 is a concave arc surface, so that the rolling element 420 can rotate freely in the positioning cavity 415, and the spherical surface of the rolling element 420 abuts and squeezes the power cord 120. Through the self-rotation of the rolling element 420, not only can the smoothness of the passage of the power cord 120 be improved, but the power cord 120 can also be straightened to avoid jamming and tangling.

[0038] In some embodiments, the rolling element 420 is made of plastic, metal steel or ceramic.

[0039] See also Figures 2 to 4 Optionally, the materials of the rolling elements 420 are the same, or the materials of at least two rolling elements 420 are different. This is not limited here and can be selected according to actual conditions.

[0040] Optionally, the rolling element 420 may be made of plastic, which has the following characteristics:

[0041] Lightweight: Plastic materials are lighter than metal materials, so the ball bearings made of plastic are lightweight, which is beneficial to reducing the total weight of the wire drawing structure 400.

[0042] Corrosion resistance: Plastic materials generally have good corrosion resistance and can resist the erosion of some chemicals. When the power cord 120 is bonded with cleaning liquid, the ball bearings can also resist the corrosion of the cleaning liquid.

[0043] Insulation performance: Plastic is an insulating material, so the ball made of plastic has good insulation performance and will not be electrically connected to the power cord 120.

[0044] Low noise: Balls made of plastic produce less friction noise during movement, thus having a lower noise level.

[0045] Optionally, the rolling element 420 may be made of metal steel, which has the following characteristics:

[0046] High strength: Metal steel materials have high strength and hardness, so the balls made of metal have excellent load-bearing capacity and wear resistance and can withstand large loads and impacts.

[0047] Wear resistance: Metal steel material has good wear resistance and can maintain good surface quality during high-speed operation and long-term use, thus extending the service life of the ball.

[0048] High stability: Balls made of metal have good stability under various environmental conditions and are not easily corroded by chemicals and affected by environmental changes.

[0049] Optionally, the rolling element 420 may be made of ceramic, which has the following characteristics:

[0050] High hardness: Ceramic materials generally have higher hardness, which is harder than metal materials. Therefore, balls made of ceramics have excellent wear resistance and can maintain a smooth surface under high-speed operation and high load.

[0051] Lightweight: Ceramic materials are lighter than metal materials, so ceramic balls have lower inertia and friction resistance, which can reduce dynamic friction with the power cord 120 and energy consumption.

[0052] Corrosion resistance: Ceramic materials have excellent corrosion resistance and can operate stably for a long time in harsh environments such as humidity, acid and alkali, and are not easy to rust and corrode.

[0053] Insulation performance: Ceramic material is an insulating material with good insulation performance, which can prevent the occurrence of problems such as static electricity and electric sparks.

It can be understood that the reverse process of the above process can separate the wire-winding base 412 from the wire-winding upper cover 411.

[0061] In some embodiments, two of the buckle feet 413 are arranged at intervals, and the wire hole 414 is located between the two buckle feet 413 .
