Description

Technical Field

[0001] The present application relates to the technical field of tires, and in particular to a tire for a lawn mowing robot. Background Art

[0002] A lawn mowing robot is a new category developed on the basis of a traditional lawn mower, which can autonomously complete the work of trimming the lawn without direct human control and operation. Lawn mowing robots generally have functions such as automatic lawn mowing, grass clippings cleaning, automatic rain avoidance, automatic walking, automatic obstacle avoidance, electronic virtual fence, automatic return to charging, and network control, and are suitable for lawn trimming and maintenance in places such as family courtyards and public green spaces.

[0003] Due to the special application scenario of the lawn mowing robot, its tires need to come into contact with the soil during operation. In order to increase the friction of the tires, patterns are generally formed on the tire surface. During walking, soil is more likely to be embedded in the patterns, and at the same time, a certain amount of soil is scattered during walking; for this reason, the present application aims at the tires for lawn mowers. Summary of the Utility Model

[0004] The purpose of the present application is to provide a tire for a lawn mowing robot to solve at least one of the above technical problems.

[0005] To solve the above technical problems, the present application provides a tire for a lawn mowing robot, including a tire body; a first anti-slip block is provided on the outer tread surface of the tire body, and a plurality of the first anti-slip blocks are provided and are in a herringbone shape;

[0006] The width of the first anti-slip block gradually decreases from the middle to both ends;

[0007] A plurality of the first anti-slip blocks are evenly distributed around the axis of the tire body at equal intervals, and a guiding groove is formed between two adjacent first anti-slip blocks, and the guiding groove gradually increases from the middle to both sides;

[0008] Second anti-slip blocks are provided on the outer tread surface of the tire body near both ends, and a plurality of the second anti-slip blocks are provided and are evenly distributed around the axis of the tire body at equal intervals;

[0009] In the above implementation process, in this solution, the first anti-slip block is in a herringbone shape, and its width gradually decreases from the middle to both ends. The guiding groove is formed between two adjacent first anti-slip blocks. In this way, the shape of the guiding groove gradually increases from the middle to both sides. When the tire is embedded in the soil, the guiding groove of this structure can promote the soil entering the guiding groove to be discharged from the wider positions on both sides, so as to effectively prevent the soil in the guiding groove from being thrown out when the tire rotates; in addition, this solution further provides second anti-slip blocks, and the second anti-slip blocks are arranged on both sides of the first anti-slip block, so as to enhance the anti-slip ability of the side of the tire, thereby improving the comprehensive anti-slip performance of the tire.

[0010] Preferably, the second anti-slip block is arranged on one side of the first anti-slip block and is located between two adjacent first anti-slip blocks;

[0011] Preferably, arc-shaped inclined surfaces are formed at both ends of the tire body, and the second anti-slip block is arranged on the arc-shaped inclined surfaces;

[0012] In the above implementation process, the second anti-slip block is arranged on one side of the first anti-slip block and is located between two adjacent first anti-slip blocks. By being arranged in an alternating manner with the first anti-slip blocks, the contact surface is more uniform when the tire contacts the ground; further, the second anti-slip block is arranged on the arc-shaped inclined surface. Although it is located between two first anti-slip blocks, due to the difference in the angle of the inclined surface, it will not have too much impact on the export of the soil in the guiding groove.

[0013] Preferably, convex columns are arranged side by side on the first anti-slip block, and the ends of the convex columns are conical;

[0014] In the above implementation process, the present solution further arranges convex columns on the first anti-slip block, which can enhance the grip of the tire, and at the same time assist in improving the obstacle-crossing ability and climbing ability of the lawn mowing robot, and reduce the probability of tire slipping.

[0015] Preferably, the longitudinal section of the first anti-slip block is trapezoidal;

[0016] In the above implementation process, the longitudinal section of the first anti-slip block is trapezoidal. In this way, two adjacent first anti-slip blocks form an open structure, which can reduce the probability of soil embedding and residue, and further reduce the probability of soil flying.

[0017] Preferably, the angle of the herringbone of the first anti-slip block is 115° - 118°;

[0018] Preferably, a plurality of buffer holes are formed axially through the tire body;

[0019] The plurality of buffer holes are equiangularly distributed around the axis of the tire body;

[0020] In the above implementation process, the present solution further arranges a plurality of buffer holes, which can effectively improve the deformation buffer performance of the tire, and further improve the seismic buffer ability of the lawn mowing robot.

[0021] Preferably, an annular buffer ring is arranged in the buffer hole;

[0022] In the above implementation process, the present solution further adds a buffer ring in the buffer hole. While the buffer holes endow the tire with sufficient buffer and seismic resistance, it also takes into account a certain tire strength and improves its deformation reset performance.

[0023] Compared with the prior art, the beneficial effects of the present application are as follows: In this solution, the first anti-slip block is in a herringbone shape, and its width gradually decreases from the middle to both ends. Two adjacent first anti-slip blocks form a guiding groove, so that the shape of the guiding groove gradually increases from the middle to both sides. When the tire is embedded in the soil, the guiding groove of this structure can prompt the soil entering the guiding groove to be discharged from the wider positions on both sides, so as to effectively prevent the soil in the guiding groove from being thrown out when the tire rotates; in addition, this solution further sets a second anti-slip block, and the second anti-slip block is arranged on both sides of the first anti-slip block, so as to enhance the anti-slip ability of the tire side and thus improve the comprehensive anti-slip performance of the tire.

[0035] Embodiment: Due to the special application scenario of the lawn mowing robot, its tires need to contact the soil during the working process. In order to increase the friction of the tires, patterns are generally formed on the tire surface. During walking, soil is more likely to be embedded in the patterns, and at the same time, a certain amount of soil flying phenomenon is caused during walking.

[0046] Specifically, the longitudinal section of the first anti-slip block 20 is trapezoidal;

[0047] In the above solution, the longitudinal section of the first anti-slip block 20 is trapezoidal, so that two adjacent first anti-slip blocks 20 form an open structure, which can reduce the probability of soil embedding and residue, and further reduce the probability of soil flying.

[0048] Furthermore, in one of the embodiments, the angle of the herringbone of the first anti-slip block 20 is 115° - 118°.
