Technical Field

[0001] The utility model relates to the technical field of rubber wheels, and more specifically to a rubber wheel for robot competitions. Background Art

[0002] With the rapid development of intelligent technology and the continuous update of educational concepts, as a technology that combines cutting-edge technologies such as information technology, electronic engineering, mechanical engineering, control theory, sensing technology, and artificial intelligence, robot technology is also contributing to educational reform. In order to promote the development of robot technology and cultivate students' innovative abilities, a series of robot competitions have emerged worldwide.

[0003] The mobility of wheeled mobile robots is one of their advantages, but at the same time, it also leads to poor stability. When encountering uneven ground, steep slopes, or collisions, wheeled mobile robots are prone to losing balance, tipping over, or being unable to move forward, thus affecting their work efficiency and operation safety. Currently, the tires used in existing wheeled mobile robots have a relatively limited scope of application and poor grip, resulting in great limitations in mobility and traction. When used in indoor environments, the friction and vibration with the ground will generate relatively large noise, which will pose a potential hazard to human health and affect the work efficiency and quality of life of staff.

[0004] Therefore, it is an urgent problem for those skilled in the art to provide a rubber wheel for robot competitions that is easy to install, has strong grip, and low noise. Summary of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solutions, mainly including:

[0007] A rubber wheel for robot competitions, including a wheel disc and a wheel body.

[0008] The wheel disc is composed of a wheel rim and a wheel plate. The wheel rim is provided with teeth, the center of the wheel plate is provided with a polygonal hub, a second through hole is opened in the polygonal hub, and a plurality of circular hubs are also provided on the wheel plate, and a third through hole is opened in the circular hub.

[0009] The wheel body has first installation grooves opened on both sides, a second installation hole is opened at the center of the first installation groove, a plurality of second installation grooves are opened in the first installation groove, and a plurality of first installation holes are opened in the first installation groove.

[0010] The roulette is installed inside the first installation grooves on both sides of the wheel body. There is an interference fit between the roulette and the wheel body. The polygonal hub of the roulette is fitted into the second installation holes of the wheel body, and the circular hubs of the roulette are respectively fitted into the first installation holes and the second installation grooves of the wheel body.

[0011] Preferably, the roulette is in the shape of a gear and is made of hard plastic material, such as materials like polycarbonate and polypropylene, and is integrally die-cast.

[0012] Preferably, the wheel body is made of rubber material.

[0013] Preferably, a number of first through holes with the same positions and equal sizes are provided on the roulette and the wheel body. The first through holes are "C"-shaped through holes, and the notches face the center of the circle.

[0014] Preferably, the first installation groove is a gear-shaped groove, and the first installation groove has the same diameter as the roulette.

[0015] Through the above technical solutions, compared with the prior art, the present utility model combines the roulette and the wheel body, improves the support stress of the tire, is used to support the tire, buffer external impacts, and realize the contact between the tire and the road surface. Multiple teeth are provided on the rim of the roulette and are fitted with the wheel body, which improves the connection strength between the roulette and the wheel body. The wheel body is made of rubber material, reducing the friction and vibration between the tire and the ground, improving the grip, reducing the noise. The roulette adopts a polygonal hub, further improving the transmission efficiency of the axle to the tire. At the same time, the overall shape of this application has a special aesthetic feeling, high ornamental value, and is convenient for popularization. BRIEF DESCRIPTION OF THE DRAWINGS
