[0046] like Figure 1 As shown, in an embodiment, a tire 1000 is provided, which can be applied to the moving wheel of the surface cleaning device, and can reduce the problem of slipping of the surface cleaning device during movement on a smooth ground or a ground with accumulated water.
[0047] The surface cleaning equipment may include but is not limited to floor scrubbers, mops, sweepers and the like.
[0048] like Figure 1 , Figure 4 and Figure 5 As shown, the tire 1000 may include a tire body 100. The tire body 100 may include a first side 101 and a second side 102 disposed in opposite directions. The first side 101 may be located on a side of the tire body 100 that is away from the central axis L of the tire 1000, and the second side 102 may be located on a side of the tire body 100 that is toward the central axis L of the tire 1000. That is, the first side 101 may refer to the outer side of the tire body 100, and the second side 102 may refer to the inner side of the tire body 100.
[0049] like Figures 1 to 5 As shown, in some embodiments, at least one group of anti-skid units 200 is protrudingly provided on the first side 101 of the tire body 100. The anti-skid unit 200 includes a plurality of anti-skid tooth modules 210, and the plurality of anti-skid tooth modules 210 may be sequentially distributed along the circumference of the tire 1000. Any two adjacent anti-skid tooth modules 210 are arranged at intervals and form a first drainage groove 221. The first drainage groove 221 may be extended along the axial direction of the tire 1000. In some embodiments, the anti-skid unit 200 and the tire body 100 may be an integrated structure.
[0050] The axial direction of the tire 1000 may be parallel to the extension direction of the central axis L. The circumferential direction of the tire 1000 may refer to the direction of the outer contour of the cross section of the tire body 100 perpendicular to the central axis L.
[0051] In some embodiments, the anti-skid tooth module 210 may include at least one anti-skid tooth group 211. The anti-skid tooth group 211 may include a plurality of anti-skid teeth 2111, and the plurality of anti-skid teeth 2111 are sequentially arranged along the axial direction of the tire 1000. Any two adjacent anti-skid teeth 2111 are arranged at intervals, and a second drainage groove 222 is formed between any two adjacent anti-skid teeth 2111. The second drainage groove 222 may be extended along the circumference of the tire 1000. In some embodiments, the side surface of the anti-skid teeth 2111 facing away from the tire body 100, that is, the surface facing the outside or in contact with the outside, may be a curved surface.
[0052] In other embodiments, the surface of the anti-slip teeth 2111 facing away from the tire body 100, that is, the surface facing the outside world or in contact with the outside world, may also be set to be a plane.
[0053] The tire 1000 provided by the present application can increase the friction between the tire 1000 and the ground when passing through a relatively smooth ground, thereby reducing the probability of slipping. When passing through a ground with accumulated water, the accumulated water can be diverted to the first drainage groove 221 and the second drainage groove 222, thereby reducing the amount of accumulated water between the surface of the side of the anti-skid teeth 2111 away from the tire body 100 and the ground, thereby reducing the probability of slipping of the tire 1000 and ensuring that the surface cleaning device using the tire 1000 works normally.
[0054] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the first side 101 of the tire body 100 may be protrudingly provided with two groups of anti-skid units 200, namely, a first anti-skid unit 201 and a second anti-skid unit 202. The first anti-skid unit 201 and the second anti-skid unit 202 may be sequentially arranged along the axial direction of the tire 1000. The first anti-skid unit 201 and the second anti-skid unit 202 are spaced apart, and a third drainage groove 223 is formed between the first anti-skid unit 201 and the second anti-skid unit 202, and the third drainage groove 223 may be arranged along the circumference of the tire 1000. Thus, the drainage volume of the tire 1000 can be further increased, the water accumulation between the surface of the side of the anti-skid teeth 2111 away from the tire body 100 and the ground can be reduced, the friction between the tire 1000 and the ground can be increased, the probability of the tire 1000 slipping can be reduced, and the obstacle crossing ability of the tire 1000 to smoothly cross the water can also be improved.
[0055] In other embodiments, the first side 101 of the tire body 100 may also be protrudingly provided with one, three, four, five, six or any other number of anti-skid units 200. When the first side 101 of the tire body 100 is provided with multiple groups of anti-skid units 200, the multiple groups of anti-skid units 200 may be sequentially spaced along the axial direction of the tire 1000, and a third drainage groove 223 may be formed along the circumferential direction of the tire body 100 between any two adjacent groups of anti-skid units 200.
[0056] In some embodiments, the third drainage groove 223 can be respectively connected to the first drainage groove 221 and the second drainage groove 222. The first drainage groove 221, the second drainage groove 222 and the third drainage groove 223 can also drain water from each other to reduce the accumulation of water between the anti-skid teeth 2111 and the ground, thereby reducing the possibility of the tire 1000 slipping.
[0057] like Figure 1 and Figure 2 As shown, in some embodiments, the structures of the two groups of anti-skid units 200 can be set to be similar. Accordingly, the first anti-skid unit 201 and the second anti-skid unit 202 can both include multiple anti-skid tooth modules 210. In the embodiment, the multiple anti-skid tooth modules 210 in the first anti-skid unit 201 can be staggered with the multiple anti-skid tooth modules 210 in the second anti-skid unit 202 along the circumferential direction of the tire body 100, so as to ensure that the anti-skid teeth 2111 are always in contact with the ground, ensure the friction between the tire 1000 and the ground, improve the grip of the tire 1000, and reduce the possibility of the tire 1000 slipping.
[0058] In some other embodiments, the multiple anti-skid tooth modules 210 in the first anti-skid unit 201 may also be arranged in a one-to-one correspondence with the multiple anti-skid tooth modules 210 in the second anti-skid unit 202 .
[0059] In some embodiments, the anti-skid unit 200 may include ten groups, sixteen groups, twenty groups, twenty-five groups or any other number of anti-skid tooth modules 210, which may be specifically configured according to the size of the tire 1000 and are not specifically limited herein.
[0060] like Figure 2 and Figure 3 As shown, in some embodiments, the anti-skid tooth module 210 may include multiple groups of anti-skid tooth groups 211, and the multiple groups of anti-skid tooth groups 211 may be sequentially spaced along the circumference of the tire 1000. A fourth drainage groove 224 may be disposed between any two adjacent groups of anti-skid tooth groups 211, and the fourth drainage groove 224 may be extended along the axial direction of the tire 1000. Thus, the friction between the tire 1000 and the ground and the drainage capacity can be further increased, and the probability of the tire 1000 slipping can be reduced.
[0061] For example, in some embodiments, the anti-slip tooth module 210 may include two, three, four, six, or other numbers of anti-slip tooth groups 211, and there is no specific limitation thereto.
[0062] In some other embodiments, the anti-slip tooth module 210 may also include a set of anti-slip tooth groups 211 .
[0063] like Figure 2 and Figure 3As shown, in some embodiments, the anti-slip tooth set 211 may include six, eight, nine, twelve or any other number of anti-slip teeth 2111 , and the number of the anti-slip teeth 2111 is greater than or equal to two, and there is no specific limitation.
[0064] In some embodiments, in the axial direction of the tire 1000, the width n of the anti-skid teeth 2111 may be greater than the width m of the second drainage groove 222. Thus, during the movement such as turning, it can be ensured that the anti-skid teeth 2111 are always in contact with the ground, thereby increasing the grip between the tire 1000 and the ground and reducing the probability of the tire 1000 slipping.
[0065] like Figure 1 , Figure 4 and Figure 5 As shown, the tire body 100 further includes a first end 103 and a second end 104 disposed axially along the tire 1000. In some embodiments, the first anti-skid unit 201 may be disposed near the first end 103, and the second anti-skid unit 202 may be disposed near the second end 104.
[0066] In some embodiments, the first end 103 of the tire body 100 may be provided with a first hollow groove group 111 , and the second end 104 of the tire body 100 may be provided with a second hollow groove group 112 .
[0067] In some embodiments, the first hollow groove group 111 may include a plurality of first hollow grooves 1101 and a plurality of second hollow grooves 1102. The plurality of first hollow grooves 1101 and the plurality of second hollow grooves 1102 may be arranged alternately in sequence along the circumferential direction of the tire 1000. The first hollow groove 1101 and the second hollow groove 1102 may both have a certain extension length along the axial direction of the tire 1000, and the first hollow groove 1101 and the second hollow groove 1102 are both blind grooves. Exemplarily, the size of the first hollow groove 1101 in the axial direction of the tire 1000 and the size of the second hollow groove 1102 in the axial direction of the tire 1000 may be slightly smaller than half of the size of the tire body 100 in the axial direction of the tire 1000.
[0068] In some embodiments, the cross-sectional shape of the first hollow groove 1101 may be inverted with the cross-sectional shape of the second hollow groove 1102. The cross-sectional shape of the first hollow groove 1101 and the cross-sectional shape of the second hollow groove 1102 are both perpendicular to the axial direction of the tire 1000. Exemplarily, the cross-sectional shape of the first hollow groove 1101 and the cross-sectional shape of the second hollow groove 1102 are both trapezoidal, and the cross-sectional shape of the second hollow groove 1102 may be inverted relative to the cross-sectional shape of the first hollow groove 1101.
[0069] In other embodiments, the cross-sectional shape of the first hollow groove 1101 and the cross-sectional shape of the second hollow groove 1102 can both be set to be a triangle.
[0070] In other embodiments, the cross-sectional shape of the first hollow groove 1101 may be different from the cross-sectional shape of the second hollow groove 1102. For example, the cross-sectional shape of the first hollow groove 1101 may be set to a trapezoid, the cross-sectional shape of the second hollow groove 1102 may be set to a triangle, and the shape of the second hollow groove 1102 may be inverted relative to the shape of the first hollow groove 1101.
[0071] In the embodiment, the first hollow groove group 111 may have a similar structure to the second hollow groove group 112. In some embodiments, the first hollow groove 1101 in the first hollow groove group 111 may be arranged opposite to the second hollow groove 1102 in the second hollow groove group 112. The second hollow groove 1102 in the first hollow groove group 111 may be arranged opposite to the first hollow groove 1101 in the second hollow groove group 112.
[0072] In some other embodiments, the first end 103 or the second end 104 of the tire body 100 is provided with a hollow groove group 110. Moreover, the first hollow groove 1101 and the second hollow groove 1102 provided on the tire body 100 are both blind grooves.
[0073] In other embodiments, a first hollow groove group 111 is provided on the tire body 100, and the first hollow groove group 111 includes a plurality of first hollow grooves 1101 and a plurality of second hollow grooves 1102, and the plurality of first hollow grooves 1101 and the plurality of second hollow grooves 1102 can be sequentially staggered along the circumferential direction of the tire 1000. Both the first hollow groove 1101 and the second hollow groove 1102 can be through grooves, that is, the first hollow groove 1101 and the second hollow groove 1102 both penetrate the tire body 100 along the axial direction of the tire 1000.
[0074] In the embodiment of the present application, by providing the hollow groove group 110 on the tire body 100, the elasticity of the tire 1000 can be improved, thereby improving the shock absorption performance of the tire 1000, and at the same time, the contact area between the tire 1000 and the ground can be increased, the grip can be increased, and the probability of the tire 1000 slipping can be further reduced. In addition, the weight of the tire 1000 itself can also be reduced, the amount of materials used can be reduced, and the material cost can be reduced.
[0075] like Figures 6 to 8 As shown, a moving wheel is also provided in the embodiment, which may include a wheel hub 2000, a cover plate 3000 and a tire 1000 provided in the embodiment.
[0076] The tire body 100 is sleeved on the circumference of the wheel hub 2000.

The anti-skid unit 200 can be located on the side of the tire body 100 away from the wheel hub 2000 and can be used to contact the ground. In some embodiments, the wheel hub 2000 can be arranged near the first end 103 of the tire body 100.
[0077] The cover plate 3000 can be fixedly connected to the wheel hub 2000 by screw connection or the like, and is located on a side of the wheel hub 2000 facing the second end 104 of the tire body 100 .

In an embodiment, the connecting ring 300 may have a certain extension length along the radial direction of the tire 1000. The connecting ring 300 may be inserted between the wheel hub 2000 and the cover plate 3000, and clamped and fixed by the wheel hub 2000 and the cover plate 3000. Thus, the tire 1000 may be further fixed, the stability of the installation of the tire 1000 and the wheel hub 2000 may be improved, and the tire 1000 may be prevented from being separated from the wheel hub 2000 at will.

The first limiting protrusion 2100 is inserted into the first limiting hole 310 to limit the circumferential position between the tire 1000 and the wheel hub 2000, and prevent the tire 1000 and the wheel hub 2000 from rotating relative to each other. In the embodiment, the number of groups of the first limiting protrusion 2100 and the first limiting hole 310 can be set as required, for example, the number of groups of the first limiting protrusion 2100 and the first limiting hole 310 can be set to one group, two groups, five groups, six groups, etc.
[0080] In other embodiments, the first limiting hole 310 may be replaced by a blind groove, and the opening of the blind groove may face one side of the first limiting protrusion 2100 .
[0081] In some embodiments, the cover plate 3000 is provided with a second limiting protrusion 3100 protruding toward one side of the connecting ring 300, and the connecting ring 300 is provided with a second limiting hole 320 adapted to the second limiting protrusion 3100. The second limiting protrusion 3100 can be inserted into the second limiting hole 320 to limit the position between the tire 1000 and the cover plate 3000, and the relative rotation between the cover plate 3000 and the tire 1000 can be prevented. In the embodiment, the number of groups of the second limiting protrusion 3100 and the second limiting hole 320 can be set as needed, for example, the number of groups of the second limiting protrusion 3100 and the second limiting hole 320 can be set to one group, two groups, five groups or six groups, etc.
[0082] In some embodiments, when a plurality of the first limiting holes 310 and a plurality of the second limiting holes 320 are provided, the plurality of first limiting holes 310 and the plurality of second limiting holes 320 may be alternately arranged in sequence.
[0083] In other embodiments, the second limiting hole 320 may be replaced by a blind groove, and the opening of the blind groove may face one side of the second limiting protrusion 3100 .
