Indeed, in other embodiments, the third gap 544 may be disposed at other positions of the gear tooth 5411, and the direction of the third gap may be other, which is not specifically limited herein, depending on the actual situation.

Referring to fig. 2 and 4, in the driving process of the cleaning robot 100, since the tire 5 is deformed by a positive pressure after contacting the surface of the object, in order to increase the contact surface between the tire 5 and the surface of the object to enhance the overall grip of the tire 5, each carcass 51 further includes a set of first openings 52 distributed along the circumferential direction of the carcass 51, and the first openings 52 can be deformed by a force to increase the contact area between the tire 5 and the surface of the object. The first opening 52 is disposed radially inward of the gear tooth assembly 541 along the tire 5. The first opening 52 is located below the gear tooth assembly 541 in the overall height direction of the tire 5. As mentioned above, each gear tooth assembly 541 includes three gear teeth 5411, and the first aperture 52 opens below the centrally located gear tooth 5411 in each gear tooth assembly 541. Accordingly, the first openings 52 between each two adjacent carcasses 51 are arranged in a staggered manner. In the present embodiment, the cross-sectional shape of the first opening 52 is a regular hexagon. The regular shape of the regular hexagon is designed in such a way that after the tire 5 is deformed by a force, the first opening 52 with the regular hexagon can guide the deformation direction of the tire body 51, so that the stress state of the whole tire body 51 is consistent, and the purpose of protecting the tire body 51 is achieved. Indeed, in other embodiments, the cross-sectional shape of the first opening 52 may be other, and is not limited to the specific shape according to the actual situation. In addition, the first opening 52 may or may not be disposed through each carcass 51, and is not particularly limited herein according to the actual situation.

Each carcass 51 further includes a plurality of support ribs 55, and the plurality of support ribs 55 are distributed in the circumferential direction of the tire 5 and are disposed inside the first slit 542 in the radial direction of the tire 5, that is, the support ribs 55 are located below the first slit 542 and are disposed coaxially with the first slit 542. Accordingly, the first opening 52 is provided with support ribs 55 on both sides. The support ribs 55 serve to reduce deformation of the first slits 542 when the first slits 542 are in contact with the surface of the object to facilitate engagement with an obstacle and thus facilitate obstacle crossing.

Each carcass 51 further includes a second opening 53 disposed between the support rib 55 and the first opening 52, in this embodiment, only one second opening 53 is disposed between the first opening 52 and the support rib 55, correspondingly, the second openings 53 are disposed on both sides of each first opening 52, two second openings 53 are disposed between two adjacent first openings 52, and the two second openings 53 are disposed in a mirror image manner along the support rib 55. In the present embodiment, the second opening 53 has a crescent-shaped cross section. The crescent-shaped second opening 53 has a first side 531 located below the first gap 542 and away from the first opening 52, a second side 532 located below the gear teeth 5411 and close to the first opening 52, and a connecting side 533 for connecting the first side 531 and the second side 532. The first side 531 is straight to provide support to reduce deformation of the first gap 542; the second side 532 is curved to further guide the deformation of the tire 5 to increase the contact area.

Each carcass 51 further comprises an inner surface 512 disposed opposite outer surface 511, and tire 5 further comprises a mounting portion 56 disposed in cooperation with the hub, mounting portion 56 being disposed on inner surface 512. In this embodiment, the mounting portion 56 is a protrusion 56 protruding outward from the inner surface 512, and correspondingly, a slot for engaging with the protrusion 56 is disposed on the hub, so that the tire 5 and the hub can be mounted quickly and conveniently. Indeed, in other embodiments, the mounting portion 56 may be other, and is not limited herein, as the case may be.

The embodiment can realize the obstacle crossing function and the anti-skid function at the same time. However, in some application scenarios, if the obstacle crossing function of the tire 5 is enhanced, only the first opening 52 may be disposed on the tire 5, and the first opening 52 is disposed inside the gear tooth assembly 541; or, if the anti-skid function of the tire 5 is enhanced, only the first gap 542 and the second gap 543 may be provided in the tire 5, and the present invention is not limited thereto.

In summary, the following steps: by arranging the first opening 52 on the tire body 51, the first opening 52 can be stressed and deformed when being in contact with the surface of a target object, so that the contact area between the tire pattern 54 of the tire body 51 and the surface of the target object is increased, the contact surface of the tire 5 is further enhanced, and the effect of enhancing the friction force is achieved; meanwhile, the tire 5 can easily get over obstacles as a whole due to the deformation of the tire body 51, and is convenient and quick;

the first gap 542 is arranged between the two adjacent gear tooth assemblies 541, the second gap 543 is arranged between the two adjacent gear teeth 5411, and the width of the first gap 542 is larger than that of the second gap 543, so that the first gap 542 and the second gap 543 are engaged when the tire 5 crosses an obstacle, and the tire 5 can accommodate obstacles with different volumes, so that the tire 5 climbs on the obstacle and then crosses the obstacle without being blocked by the obstacle, and the device is convenient and fast; meanwhile, due to the existence of the first gap 542 and the second gap 543, the tire 5 deforms in the process of contacting with the target object, so as to achieve the effect of increasing the friction force.
