Detailed Description of the Invention

[0014] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure.

[0015] All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0016] Refer to Figures 1-3 .

[0017] The utility model provides a magnetic wheel drive structure, which includes a driving wheel 1 and a driven wheel 2; the driving wheel 1 includes a driving wheel body 10 and a first annular magnet group 11 sleeved on the driving wheel body 10. The first annular magnet group 11 includes several first sector-shaped magnets 110 connected end to end in a ring shape. The two poles of adjacent first sector-shaped magnets 110 are arranged in opposite directions, and the two poles of the first sector-shaped magnet 110 are respectively arranged on its outer arc and inner arc sides; the driven wheel 2 includes a driven wheel body 20 and a second annular magnet group 21 sleeved on the driven wheel body 20. The second annular magnet group 21 includes several second sector-shaped magnets 210 connected end to end in a ring shape. The two poles of adjacent second sector-shaped magnets 210 are arranged in opposite directions, and the two poles of the second sector-shaped magnet 210 are respectively arranged on its two end faces. The central axes of the driving wheel body 10 and the driven wheel body 20 are orthogonally arranged, and the driving wheel 1 can roll on one end face of the driven wheel 2.

[0018] Its working principle is as follows: fix the rotating shaft of the driving end on the driving wheel body 10, fix the rotating shaft of the driven end on the driven wheel body 20, place the driving wheel 1 on one end face of the driven wheel 2, and make the central axes of the driving wheel body 10 and the driven wheel body 20 orthogonal. In order to avoid abrasion of the driven wheel 2 caused by the rolling of the driving wheel 1, a gap can be left between the driving wheel 1 and the driven wheel 2. Since the two poles of adjacent first sector-shaped magnets 110 in the first annular magnet group 11 are arranged in opposite directions, and the two poles of adjacent second sector-shaped magnets 210 in the second annular magnet group 21 are arranged in opposite directions, when the same poles of the first sector-shaped magnet 110 and the second sector-shaped magnet 210 are close to each other, a repulsive force will be generated, and when the opposite poles of the first sector-shaped magnet 110 and the second sector-shaped magnet 210 are close to each other, an attractive force will be generated. By driving the driving wheel 1 to rotate on the end face of the driven wheel 2 and under the inertial action of the driven wheel 2, the driven wheel 2 can be driven to rotate, realizing the transmission function between the driving wheel 1 and the driven wheel 2, effectively reducing the transmission energy loss, reducing the abrasion of the driving wheel 1 and the driven wheel 2, reducing the maintenance frequency, reducing the use cost, and having high transmission stability.

[0019] Based on the above embodiment, the outer arc length of the first sector-shaped magnet 110 is greater than the inner arc length of the second sector-shaped magnet 210. During the rotation of the driving wheel 1, when the same poles of the first sector-shaped magnet 110 and the second sector-shaped magnet 210 are close to each other, the first sector-shaped magnet 110 will generate a repulsive force with the second sector-shaped magnet 210. When the first sector-shaped magnet 110 passes over the second sector-shaped magnet 210 and approaches the next adjacent second sector-shaped magnet 210, the first sector-shaped magnet 110 will generate an attractive force with the next second sector-shaped magnet 210, and so on, so that the driven wheel 2 continuously rotates in the same direction.

[0020] Based on the above embodiments, the driving wheel 1 further includes a first sleeve 12. The driving wheel body 10 includes a first disc 100 having an inner arc radius consistent with that of the first sector-shaped annular magnet 110, and a first limiting disc 101 provided at one end of the first disc 100. The inner wall of the first sector-shaped annular magnet 110 is attached to the outer wall of the first disc 100, and one end face of the first sector-shaped annular magnet 110 is adjacent to the inner end face of the first limiting disc 101. The first sleeve 12 includes a first cylindrical portion 120 matching the first limiting disc 101, and a first annular limiting portion 121 connected to the inner edge of one end of the first cylindrical portion 120. The outer arc radius of the first sector-shaped annular magnet 110 is consistent with the radius of the first limiting disc 101. The first cylindrical portion 120 is sleeved on the first limiting disc 101 and the first annular magnet group 11, and the top face of the first sector-shaped annular magnet 110 is adjacent to the bottom face of the first annular limiting portion 121. The driven wheel 2 further includes a second sleeve 22. The driven wheel body 20 includes a second disc 200 having an inner arc radius consistent with that of the second sector-shaped annular magnet 210, and a second limiting disc 201 provided at one end of the second disc 200. The inner wall of the second sector-shaped annular magnet 210 is attached to the outer wall of the second disc 200, and one end face of the second sector-shaped annular magnet 210 is adjacent to the inner end face of the second limiting disc 201. The second sleeve 22 includes a second cylindrical portion 220 matching the second limiting disc 201, and a second annular limiting portion 221 connected to the inner edge of one end of the second cylindrical portion 220. The outer arc radius of the second sector-shaped annular magnet 210 is consistent with the radius of the second limiting disc 201. The second cylindrical portion 220 is sleeved on the second limiting disc 201 and the second annular magnet group 21, and the top face of the second sector-shaped annular magnet 210 is adjacent to the bottom face of the second annular limiting portion 221. The first sleeve 12 can roll on the top face of the second annular limiting portion 221. The first sleeve 12 and the second sleeve 22 respectively play a role in positioning and protecting the first annular magnet group 11 and the second annular magnet group 21, ensuring that the wheel surface of the driving wheel 1 and the top face of the driven wheel 2 are smooth and neat, and reducing the resistance between the driving wheel 1 and the driven wheel 2.

[0021] Based on the above embodiments, a first shaft hole 102 is provided through the center of the first disc 100, and a second shaft hole 202 is provided through the center of the second disc 200. The first shaft hole 102 and the second shaft hole 202 are available for the assembly of the rotating shaft, making the assembly more convenient.

A circular groove 204 is provided on one end face of the second disc 200, which can reduce the weights of the driving wheel 1 and the driven wheel 2 and reduce energy loss.
