Abstract
Description
Technical Field
[0001] The utility model relates to the field of sweeping machines, in particular to an anti-skid tire. Background Art
[0002] With the rapid development of smart home technology, sweeping robots, as intelligent devices that can walk autonomously and clean dust and debris on the floor of the home, have been widely used in various environments such as homes, offices and public places. In order to further improve cleaning efficiency and user experience, many sweeping robots have integrated the function of sweeping and mopping at the same time. However, while this function brings convenience, it also introduces a new problem - when the bottom surface being cleaned is wet, the tires of the sweeping robot are prone to slipping, affecting the cleaning effect and equipment stability. Most sweeping robots on the market currently use tires as walking parts, which can provide good grip and stability in dry environments. However, when the sweeping robot performs the mopping task, the friction between the tires and the ground decreases significantly after the ground is wetted by water or cleaning fluid, resulting in frequent slipping.

[0005] According to the anti-skid tire of the present application, the water that contacts the ground with the anti-slip block is squeezed into the drainage groove to improve the anti-skid effect of the tire, and the water is squeezed into the longitudinal drainage groove or the transverse drainage groove by the water-cutting angle of the anti-slip block. The water-cutting angle is supported by the support part to avoid excessive elastic deformation of the water-cutting angle and affect the water-cutting effect, thereby affecting the squeezing of water into the longitudinal drainage groove or the transverse drainage groove. Subsequently, as the tire rolls, the middle part of the anti-slip block can continue to squeeze water into the longitudinal drainage groove or the transverse drainage groove along the water-cutting angle. The elasticity of the middle part of the anti-slip block is increased by the large trapezoidal groove so that it can be close to the ground and the drainage effect is improved. The small trapezoidal groove can appropriately increase the elasticity of the support part to avoid excessive support effect of the support part.

[0007] Furthermore, the water-cutting angle of the anti-sliding block is not chamfered.
[0008] Furthermore, the water-cutting angle of the anti-sliding block is 85°-95°.
[0009] Furthermore, the tire is a rubber tire.
[0010] Furthermore, the anti-sliding blocks on both sides of the longitudinal drainage groove are staggered.
[0011] Furthermore, the depth of the large trapezoidal groove is the same as the depth of the small trapezoidal groove, and the depth of the large trapezoidal groove is the same as the width of the anti-sliding block. BRIEF DESCRIPTION OF THE DRAWINGS

There is a support part 23; the outer ring 1 is provided with a drainage groove and an anti-slip block 11, the drainage groove includes a longitudinal drainage groove 12 and a transverse drainage groove 13, the longitudinal drainage groove 12 is arranged in the middle of the outer ring 1, the anti-slip block 11 and the transverse drainage groove 13 are alternately arranged on both sides of the longitudinal drainage groove 12, the transverse drainage groove 13 is connected with the longitudinal drainage groove 12, the position of the anti-slip block 11 corresponds to the position of the large trapezoidal groove 21, and the support parts 23 on both sides of the large trapezoidal groove 21 correspond to the two side parts of the anti-slip block 11, and the anti-slip block 11 forms a water cutting angle 111 on the two side parts; when the tire rolls, the water cutting angle 111 on one side of the anti-slip block 11 contacts the ground first, and the support part 23 provides support for the water cutting angle 111, so that it contacts the ground stably and squeezes the water on the ground into the longitudinal drainage groove 12 or the transverse drainage groove 13, and the support part 23 provides support for the water cutting angle 111 to avoid excessive elastic deformation of the water cutting angle 111 and affect the effect of water cutting, thereby affecting the squeezing of water into The large trapezoidal groove 21 provides an elastic deformation space for the middle portion 112 of the anti-sliding plate 11. The tire continues to roll, so that the middle portion 112 of the anti-sliding plate 11 is elastically deformed so that the middle portion 112 of the anti-sliding plate 11 can be close to the ground, thereby improving the drainage effect and continuing to squeeze water into the longitudinal drainage groove 12 or the transverse drainage groove 13.
