Description

Technical Field

[0001] This utility model relates to the field of sports tools technology, specifically a floating massage mechanism. Background Technology

[0002] Currently, there is a floating massage mechanism (also known as a floating motion device or magnetic levitation motion device) that includes a base, a floating plate, a guide seat, a guide post, a spring, a coil, and a magnet. The coil is fixedly mounted on the base, and the magnet is fixedly mounted on the floating plate. The magnet and the coil are sleeved together. The guide seat, guide post, and spring are set between the floating plate and the base. One end of the spring is connected to the base, and the other end of the spring is connected to the floating plate, thus using the spring's elasticity to support the floating plate. The guide post cooperates with the guide seat to guide the movement of the floating plate. When the coil is energized, it generates an electromagnetic field. This electromagnetic field interacts with the magnet to push the magnet to move axially, thereby driving the floating plate to move, thus producing the effect of the floating plate's motion output.

[0003] As can be seen from the above, the coil and magnet are the core power structure. If a heavy object is placed on the floating plate, the coil will bear a large force due to the interaction force in order for the magnet and the floating plate to move together. Therefore, how to make the coil part lightweight and reliably fixed requires further research. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and propose a floating massage mechanism in which the coil part is lightweight and reliably fixed.

[0005] Compared with existing technologies, this utility model proposes a floating massage mechanism, including a base, a floating plate, a guide seat, a guide post, a spring, a coil, and a magnet. The magnet is fixedly mounted on the floating plate and is sleeved with the coil. The guide seat, guide post, and spring are arranged between the floating plate and the base. One end of the spring is connected to the base, and the other end is connected to the floating plate, thereby using the spring's elasticity to support the floating plate. The guide post cooperates with the guide seat to guide the movement of the floating plate. When the coil is energized, it generates an electromagnetic field, which interacts with the magnet to push the magnet's axis. The motion drives the floating plate to move, and also includes an aluminum cylindrical tube. The coil is wound around the outer peripheral wall of the aluminum cylindrical tube. After the coil is wound, the aluminum cylindrical tube is divided into upper and lower parts. The upper part is the wound part and the lower part is the non-wound part. The non-wound part is provided with a first radial connecting hole in the circumference. The base is provided with a collar. The non-wound part is fitted with the inner and outer sleeves of the collar. The collar is provided with a second connecting hole at the position corresponding to the first connecting hole. Fasteners are inserted radially from the outside to the inside of the second connecting hole and the first connecting hole to fix the non-wound part and the collar in the axial and circumferential directions.

[0006] Compared with the prior art, the present invention has the following advantages after adopting the above structure: By using an aluminum cylindrical tube to reduce weight, it is beneficial to lightness. Fasteners are inserted radially from the outside to the inside through the second and first connecting holes to fix the non-wound part and the collar axially and circumferentially. This not only facilitates assembly, but also makes it less likely for the aluminum cylindrical tube to move axially and / or rotate when the part where the coil is located is under force, thus stabilizing the coil and helping to maintain a good fit between the magnet and the coil.

[0007] In some embodiments, the aluminum cylindrical tube is configured as a thin cylindrical tube, the first connecting hole is a through hole provided in the thin cylindrical tube, and the fastener is a screw. The second connecting hole and the first connecting hole radially inserting the fastener from the outside to the inside means that the thread of the screw forms a threaded connection with the wall of the through hole.

[0008] In some embodiments, screws tighten and secure the non-wound portion to the collar via a threaded connection.

[0009] In some embodiments, the thin cylindrical tube is a cylindrical tube formed by winding and splicing aluminum sheets.

[0010] In some embodiments, the sidewall thickness of the thin cylindrical tube is less than or equal to the screw pitch.

[0011] In some embodiments, the ferrule has a radial notch, and the inlet and outlet ends of the wound coil extend downward and are led out through the radial notch. Attached Figure Description

Detailed Implementation

[0015] The following description is provided to disclose the present invention and enable those skilled in the art to implement it. The embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0016] The present invention will now be described in further detail: like Figures 1 to 2 As shown, a floating massage mechanism is disclosed, including a base 1, a floating plate 2, a guide seat 3, a guide post 4, a spring 5, a coil 6, and a magnet 7. The magnet 7 is fixedly mounted on the floating plate 2 and is sleeved with the coil 6. The guide seat 3, guide post 4, and spring 5 are arranged between the floating plate 2 and the base 1. One end of the spring 5 is connected to the base 1, and the other end of the spring 5 is connected to the floating plate 2, thereby using the spring 5 to elastically support the floating plate 2. The guide post 4 cooperates with the guide seat 3 to guide the movement of the floating plate 2. When the coil 6 is energized, it generates an electromagnetic field. This electromagnetic field interacts with the magnet 7 to push the magnet 7 to move axially, thereby driving the floating plate. 2. The movement also includes an aluminum cylindrical tube 8, on which the coil 6 is wound. After the coil 6 is wound, the aluminum cylindrical tube 8 is divided into upper and lower parts. The upper part is the wound part 9, and the lower part is the non-wound part 10. The non-wound part 10 is provided with a radial first connecting hole 11 in the circumference. The base 1 is provided with a collar 14. The non-wound part 10 and the collar 14 are fitted together in an inner and outer fit. The collar 14 is provided with a second connecting hole 12 at the position corresponding to the first connecting hole 11. Fasteners 13 are inserted radially from the outside to the inside of the second connecting hole 12 and the first connecting hole 11 to fix the non-wound part 10 and the collar 14 in the axial and circumferential directions.

[0017] Figure 1 As shown, in this example, the floating plate 2 is roughly rectangular, and a guide post 4 is connected to each of the four corners of the floating plate 2. Correspondingly, the base 1 is connected to four guide seats 3. The guide post 4 is inserted into the guide hole of the guide seat 3 to form a guide fit. There are also two springs 5. The springs 5 ​​are installed between two adjacent guide posts 4. The upper end of the spring 5 is connected to the floating plate 2, and the lower end of the spring 5 is connected to the base 1.

[0018] A collar 14 is provided between the four guide seats 3, and the magnet 7 is provided on the upper side of the collar 14 and is connected and fixed to the floating plate 2.

[0019] In some embodiments, such as Figure 1 , 2 As shown, the aluminum cylindrical tube 8 is configured as a thin-film cylindrical tube, and the first connecting hole 11 is a through hole provided in the thin-film cylindrical tube. The fastener 13 is a screw. The second connecting hole 12 and the first connecting hole 11 are radially inserted into the fastener 13 from the outside to the inside, meaning that the thread of the screw forms a threaded connection with the wall of the through hole. In this way, the structure is simple, the assembly is convenient, and the fixation after connection is relatively reliable.

[0020] Furthermore, the screws tighten and fix the non-wound portion 10 to the collar 14 via a threaded connection. In this way, the tightening setting makes the outer peripheral wall of the non-wound portion 10 fit tightly against the inner peripheral wall of the collar 14, further improving the fixing effect. In addition, it also helps to maintain the cylindrical shape of the aluminum cylindrical tube 8.

[0021] In some embodiments, such as Figure 1 , 2 As shown, the sidewall thickness of the thin cylindrical tube is less than or equal to the screw pitch. This further reduces the weight of the thin cylindrical tube and eliminates the need for internal threads in the first connecting hole 11, significantly simplifying the structure.

[0022] Furthermore, such as Figure 2 As shown, the thin-sheet cylindrical tube is a cylindrical tube made of rolled and spliced ​​aluminum sheets. This helps reduce costs, as it can be manufactured using only aluminum sheets. In this example, a single aluminum sheet is used. Figure 2 As shown, after the aluminum sheet is rolled up once, a splicing line 18 will be formed at the splicing point.

[0023] In some embodiments, such as Figure 1 As shown, the collar 14 has a radial notch 17, and the inlet end 15 and outlet end 16 of the coil 6 after winding extend downward and are led out through the radial notch 17. In this way, a structural design for how the inlet end 15 and outlet end 16 are led out is proposed, which has the advantages of simple structure, convenient wiring, and does not affect the connection and fit between the coil 6 and the magnet 7.

[0024] The magnet component 7 adopts existing technology, that is, a permanent magnet is installed on the inner circumference of the magnet component 7. The permanent magnet generates a magnetic field, which interacts with the electromagnetic field of the coil 6 to generate a force that pushes the permanent magnet, thereby driving the magnet component 7 to reciprocate along the axial direction of the coil 6.

[0025] When understanding this utility model, the above structure may be referred to other appendices if necessary. Figure 1 And that's understood, so I won't go into details here.

[0026] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
