[0014] The following is a detailed description of the specific implementation of the utility model in conjunction with the accompanying drawings:

[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "back", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0016] The utility model discloses a magnetic suspension massage chair flexible guide rail, comprising a guide rail 1 and a massage movement 2 (the massage movement 2 may have massage functions such as kneading, beating, pushing and pulling, etc., which are related to the prior art and will not be described in detail herein). The massage movement 2 is provided with a walking shaft 21, a driven shaft 22 and a walking motor 23 that drives the walking shaft 21 to rotate. The walking shaft 21 and the driven shaft 22 are both sleeved with walking wheels 24, and the walking wheels 24 are located in the guide rail 1. The guide rail 1 comprises a seat frame guide rail 11, a transition guide rail 12 and a backrest frame guide rail 13 that are sequentially arranged. In the implementation case of the utility model, permanent magnets 25 are arranged on the seat frame guide rail 11, the transition guide rail 12 and the back frame guide rail 13. The massage movement 2 is provided with a suspension magnet 26 that cooperates with the permanent magnet 25. The suspension magnet 26 is located below the permanent magnet 25, and the relative surfaces of the permanent magnet 25 and the suspension magnet 26 are magnetically repelled from each other, so that the walking wheel 24 can be against the bottom of the seat frame guide rail 11, the transition guide rail 12 and the back frame guide rail 13. Of course, the permanent magnet 25 can also be arranged below the suspension magnet 26. At this time, the relative surfaces of the permanent magnet 25 and the suspension magnet 26 are magnetically attracted to each other.

[0017] By adopting the above technical solution, when the running wheel 24 runs on the seat frame guide rail 11, the transition guide rail 12 and the backrest frame guide rail 13, an extrusion force will be generated due to the mutual repulsion of the magnetic poles of the permanent magnet 25 and the suspension magnet 26, so that the running wheel 24 can run smoothly on the bottom of the guide rail 1 to prevent it from floating or idling, and there is no need to use the combination of gears and racks, thereby avoiding the defects caused by the combination of gears and racks.

[0018] The walking wheel 24 is provided with an anti-skid sleeve 241 (the walking wheel is most preferably made of nylon material, and the anti-skid sleeve 241 is made of rubber, and an anti-skid strip can also be provided on the anti-skid sleeve 241), and the bottom of the seat frame guide rail 11, the transition guide rail 12 and the backrest frame guide rail 13 is provided with an anti-skid surface 3 (the anti-skid surface 3 can be made by sandblasting or other processes to achieve the effect of increasing roughness and increasing friction), the walking wheel 24 is against the anti-skid surface 3 through the anti-skid sleeve 241, and the anti-skid sleeve 241 can prevent the walking wheel 24 from slipping when walking, and the use of the anti-skid surface 3 can further increase the friction and prevent slipping.

[0019] A plurality of magnet fixing frames 4 are arranged on opposite sides of the massage movement 2 (it is most preferred that three fixed sheet metals are arranged side by side on opposite sides of the massage movement, and the magnet fixing frames 4 are arranged on the corresponding fixed sheet metals), each magnet fixing frame 4 is provided with a suspension magnet 26, and two guide rails 1 are correspondingly arranged, and each guide rail 1 is provided with a permanent magnet 25. The two sets of guide rails 1 can make the massage movement 2 more stable when moving, and the use of multiple suspension magnets 26 can make its force more uniform, further improving the walking stability.

[0020] The backrest guide rail 13 can rotate relative to the seat frame guide rail 11, one end of the transition guide rail 12 is hinged to the backrest guide rail 13, and the other end is hinged to the seat frame guide rail 11, the backrest guide rail 13 can lie down relatively, and the hinged transition guide rail 12 does not affect the normal movement of the massage movement 2, and the cooperation of the permanent magnet 25 and the suspended magnet 26 can make the walking wheel 24 and the bottom of the seat frame guide 11, the transition guide rail 12 and the backrest guide rail 13 squeezed, so that the anti-slip sleeve 241 produces plastic deformation, increases friction to prevent slipping, and no rack is provided, so it will not interfere relatively when lying down, so that the lying angle of the backrest guide rail 13 exceeds 180°, and the backrest guide rail 13 can be controlled to lie down by an electric push rod, etc. The specific lying down method is common knowledge and will not be introduced in detail in this article.

[0021] The formula for calculating rolling friction is:

[0022] F=μ×N‌, where F is the rolling friction, μ is the rolling friction coefficient, and N is the normal reaction force.

[0023] The formula for calculating the magnetic force of a magnet is as follows:

[0024] (1) Calculation formula for permanent magnet magnetic field force: F = μ0 / (4S(H / δ)²) μ0 is the vacuum magnetic permeability, H is the permanent magnet magnetomotive force, S is the permanent magnet surface area, and δ is the air gap.

[0025] (2) Magnetic field force formula: F = mH, where m is the magnetic pole strength and H is the magnetic field strength. The magnetic field strength generated by the magnetic pole is inversely proportional to the cube of the distance r.

[0026] In summary: it can effectively avoid abnormal noise, tooth skipping, gear rack breakage and other problems caused by rack misalignment, displacement, wear and other factors, improve the user experience of the massage chair, and can achieve a maximum opening angle of 180° or more for the flexible guide rail, expand the application scope and use effect of the massage chair, and meet the market demand for efficient and comfortable massage chairs. Secondly, in the field of flexible guide rail technology, the magnetic levitation technology of this product can achieve wear-free, low-noise, and high-efficiency movement of the flexible guide rail, solving the problem of limited opening angle of the existing flexible guide rail.
