[0002] Currently, the driving wheels widely used in walking robots are rubber driving wheels, which have many limitations in actual applications, affecting the robot's ability to move. For example, rubber wheels perform poorly when crossing obstacles such as steps and stones. On the one hand, rubber wheels are prone to slipping on smooth or wet surfaces, resulting in insufficient grip, affecting the stability of the robot. On the other hand, it is difficult to effectively cross obstacles, limiting its application in complex terrain. The rubber wheels of such outdoor robots are often easily contaminated with dust, mud and other dirt during driving. At the same time, water is easily accumulated in humid environments, increasing the risk of slipping and shortening the tire life. They cannot self-clean, resulting in reduced friction and increased energy consumption, further affecting their performance. As a result, it is difficult to meet the use needs of walking robots in diverse environments. Utility Model Content

[0007] The anti-slip convex point includes a first anti-slip point, a surface of the first anti-slip point is provided with a soft rubber plug groove, and a soft rubber is installed in the soft rubber plug groove;

[0008] Furthermore, the first anti-slip point and the second anti-slip point are arranged crosswise.

[0010] Furthermore, the anti-slip protrusions further include a second anti-slip point, and the surface of the second anti-slip point is not installed with soft rubber.

[0011] Furthermore, the anti-slip convex dots are arranged in a circular array on the surface of the rubber coating.

[0012] Furthermore, the obstacle-crossing grooves are arranged in a circumferential array on the surface of the rubber coating, and the obstacle-crossing grooves evenly divide the circumferential drainage grooves.

[0013] Furthermore, the arc of the obstacle groove from two points on the surface of the rubber coating layer to the axis of the rubber coating layer is at least 10°.

[0014] Furthermore, the mounting boss further comprises mounting circular holes, and a plurality of mounting circular holes are provided in an annular array on the surface of the mounting boss; the mounting circular holes (3) penetrate the mounting boss (2) and are arranged in an annular array around the axis of the mounting boss (2).

Obviously, the described embodiments are only some of the embodiments of the present disclosure / this application, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present disclosure / this application, its application, or use. Example

[0024] This embodiment provides a driving rubber-coated wheel, comprising: a mounting boss 2 and a rubber layer, wherein the surface of the mounting boss 2 is provided with mounting circular holes 3, and the mounting circular holes 3 on the surface of the mounting boss 2 are arranged in a ring shape, and the driving rubber-coated wheel is installed through the mounting circular holes 3.

[0025] The rubber layer is covered on the outer surface of the mounting boss 2; a plurality of anti-slip bumps 1 are provided on the surface of the rubber layer, a water seepage hole is provided in the middle of the anti-slip bump 1 and the water seepage hole passes through the rubber layer, that is, the middle of the anti-slip bump 1 is a hollow structure and extends to the interior of the rubber layer, and the anti-slip bumps 1 are a uniform array, so the groove formed between two adjacent anti-slip bumps 1 in the circumferential direction of the rubber layer is an axial drainage groove 5; the axial drainage grooves 5 are provided in plurality; a circumferential drainage groove 4 is provided in the circumference of the rubber layer, and the circumferential drainage groove 4 is located in the middle of the rubber layer, and the circumferential drainage groove 4 is at the same distance from the two side surfaces of the rubber layer.

[0026] In order to ensure that the driving rubber-coated wheel can be dust-proof, the soft rubber plug groove 6 on the surface of some anti-slip bumps 1 is filled with soft rubber, that is, the first anti-slip point. The soft rubber installed on the surface of the first anti-slip point can be optionally set to different materials, and at least two.

[0027] In order to realize the obstacle crossing function of driving the rubber-coated wheel, an obstacle crossing groove 7 is provided in the circumference of the rubber coating layer, and the arc of the obstacle crossing groove 7 from two points on the surface of the rubber coating layer to the axis of the rubber coating layer is at least 10°, so that there can be a sufficiently large contact area to increase the force during the obstacle crossing process.

[0028] The second anti-skid point of the anti-skid protrusion 1 is not filled with soft rubber, so that it can serve as a drainage function to drive the rubber-coated wheel.

[0030] The obstacle-crossing grooves 7 are arranged in a circumferential array on the surface of the rubber coating, and the obstacle-crossing grooves 7 evenly divide the circumferential drainage grooves 4 .

[0031] This embodiment is based on ordinary rubber wheels. In order to enable the moving robot to move effectively in dusty or wet areas, the rubber wheels are grooved in the circumferential position and also have drainage grooves in the axial direction to better drain out the water or dust squeezed during the movement. At the same time, soft rubber can be installed in the anti-slip bumps 1 between each drainage groove. Rubbers of different materials are selected to effectively solve the problem of slipping in wet areas or dust. When facing higher steps, four large obstacle grooves 7 are designed to provide greater vertical force during the obstacle crossing process. Example
