Description

TECHNICAL FIELD

[0001] The present application relates to the field of tires, more particularly, to an intelligent robot tire. BACKGROUND

[0002] A robot tire is a special tire designed for robots. Compared with traditional car tires, it has some unique characteristics. It is usually made of lightweight materials such as rubber, plastic or composite materials to reduce the weight of the robot and improve its movement efficiency and endurance.

[0003] In related technologies, in order to improve the obstacle crossing ability of intelligent robots and ensure the smooth movement of intelligent robots, for example, the existing technology with patent number CN216184251U provides a tire and a robot. The tire has the following advantages: the first protrusions and the second protrusions extend along the axial direction of the annular body and gradually bend along the circumferential direction of the annular body, so the length of the orthogonal projection of the first protrusions and the second protrusions in the plane perpendicular to the axis of the annular body is greater than the width. Even if the spacing between adjacent first protrusions is greater than the width of the first protrusions, the orthogonal projection of the adjacent first protrusions can still overlap with the orthogonal projection of the second protrusions in a partial area. Even if the spacing between adjacent second protrusions is greater than the width of the second protrusions, the orthogonal projection of the adjacent second protrusions can still overlap with the orthogonal projection of the first protrusions in a partial area. In this way, the tire can roll more smoothly, and the obstacle crossing ability of the tire is further improved, which is beneficial to the smooth operation of the robot.

[0004] Although the above-mentioned prior art solution can improve the obstacle crossing ability of the tire and facilitate the smooth operation of the robot by setting the first protrusions and the second protrusions, the anti-skid protrusions on the outer side of the first protrusions and the second protrusions are prismatic, cylindrical or hemispherical. Since the anti-skid protrusions are relatively independent, the anti-skid protrusions are prone to bending deformation during the movement of the intelligent robot, which leads to the failure of the anti-skid protrusions and reduces the service life of the tire.

[0005] In view of this, we propose an intelligent robot tire. CONTENT OF THE UTILITY MODEL

[0006] The purpose of the present application is to provide an intelligent robot tire that can effectively solve the problem in the prior art that the anti-skid protrusions are relatively independent, prone to bending deformation during the movement of the intelligent robot, leading to the failure of the anti-skid protrusions and reducing the service life of the tire.

[0015] As an optional solution of the technical scheme of the present application, the diameter of the bead is 165mm, and the circumferential diameter corresponding to the outer edge of the protrusion is 356mm.

[0016] As an optional solution of the technical scheme of the present application, the ends of the two protrusions in each group away from each other are extended to the outer side of the transition round corner, and gradually curved in the extension direction.

[0023] The application is further described in detail in combination with the accompanying drawings of the specification.

[0024] Reference Figure 1 and Figure 2 The application discloses an intelligent robot tire, which comprises a tread 1, a block 2 and a cord layer 3. The two sides of the tread 1 are fixedly provided with a sidewall 11, and the tread 1 and the sidewall 11 are integrally formed through a transition fillet 12. Every two blocks 2 are arranged in an annular array on the outer side of the tread 1, and the two blocks 2 in each group are arranged in the shape of a person. The outer side of the block 2 is provided with a protrusion 21, and the protrusion 21 is in a network shape. The cord layer 3 is a framework structure of the tire, and is fixedly arranged on the inner side of the tread 1 and the sidewall 11.

[0025] The thickness of the protrusion 2 is 15 mm, the radius of the outer edge of the protrusion 2 is 460 mm, and the radius of the cross section of the tread 1 is 445 mm. The inner side of the sidewall 11 is fixedly provided with the bead 13, and the bead 13 and the protrusion 2 form a cross section of the tire, and the thickness of the cross section is 95.5 mm. The acting width of the two protrusions 2 in each group is 106.08 mm. The diameter of the bead 13 is 165 mm, and the diameter of the circle corresponding to the outer edge of the protrusion 2 is 356 mm.

[0026] When the tire is driven to rotate by the intelligent robot, the running surface of the tire is wide, the cross section of the tire is low, the stability of the vehicle is good, and the design of the chevron pattern of the tractor tire is similar. The two protrusions 2 in each group are arranged in the shape of a "person" with a depth of 15 mm, and the outer surface is provided with a network of protrusions 21, so that the overall grip and braking performance of the tire are strong, the forward, backward and turning are flexible, and the intelligent robot can stably operate.

[0027] The sidewall 11 includes an arc segment A111 and an arc segment B112, the arc segment A111 is tangentially arranged with the arc segment B112, the arc segment A111 is tangentially arranged with the transition round corner 12, and the radii of the arc segment A111 and the arc segment B112 are 70 mm and 40 mm respectively. The cord layer 3 is woven by nylon cords with a model of 930 / dtex / 2, and the cord layer 3 is provided with two layers.
