[0010] In some embodiments, the first fastening structure is a socket, and the second fastening structure is a protrusion, which is inserted into the socket.

[0011] In some embodiments, the insertion hole is a through hole, the protrusion passes through the through hole, and the end face of the protrusion is flush with the outer surface of the first locking part.

[0012] In some embodiments, the second latch portion has two spaced upright plates that extend along a first direction and are protruded between the two upright plates, and the first latch portion is located between the two upright plates.

[0013] In some embodiments, the second strap portion is connected to one end of the two upright plates, the first buckle body is provided with a first stepped surface, and the other end of the upright plate abuts against the first stepped surface; and / or, the first buckle body is also provided with a second stepped surface, and the end of the second buckle portion away from the second strap portion abuts against the second stepped surface.

[0014] In some embodiments, the top surface of the upright plate extending in a first direction is flush with the outer surface of the first latch portion.

[0015] In some embodiments, the second buckle body includes a first shell and a second shell, with a protrusion formed on the first shell and the first shell connected to the second shell to form a second locking portion.

[0016] In some embodiments, the first buckle assembly further includes a reinforcing cover plate connected to the first buckle portion.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] like Figures 1 to 5 As shown, the magnetic latch provided in this application embodiment includes a first latch assembly 10 and a second latch assembly 20. The first latch assembly 10 includes a first latch body 11, a first magnetic member 12, and a first cover 13. The first latch body 11 has a first strap portion 111 and a first latch portion 112. The first latch portion 112 is provided with a first fastening structure 113. The first cover 13 is connected to the first latch portion 112 and forms a first mounting cavity 14 with the first latch portion 112. The first magnetic member 12 is installed in the first mounting cavity 14. The second latch assembly 20 includes a second latch body 21, a second magnetic member 22, and a second cover 23. The second latch body 21 has a second strap portion 211 and a second latch portion 212. The second latch portion 212 is provided with a second fastening structure 213. The second cover 23 is connected to the second latch portion 212 and forms a second mounting cavity 24 with the second latch portion 212. The second magnetic member 22 is installed in the second mounting cavity 24. The first magnetic member 12 and the second magnetic member 22 are magnetically attracted to each other when the first locking part 112 and the second locking part 212 overlap. Furthermore, the first fastening structure 113 and the second fastening structure 213 are detachably connected to prevent the first fastening structure 113 and the second fastening structure 213 from disengaging along the first direction, thereby completing the fastening operation between the first fastening assembly 10 and the second fastening assembly 20. When it is necessary to separate the first fastening assembly 10 and the second fastening assembly 20, simply apply a force along the second direction to separate the first locking part 112 and the second locking part 212, overcoming the magnetic attraction between the first magnetic member 12 and the second magnetic member 22. Then, the first locking part 112 and the second locking part 212 can separate from each other, completing the unfastening operation. The first direction is the arrangement direction of the first strap portion 111 and the second strap portion 211, and the second direction is the arrangement direction between the first buckle portion 112 and the second buckle portion 212 when they overlap, and the first direction is perpendicular to the second direction.

[0036] In the magnetic latch of this application embodiment, the first magnetic member 12 and the second magnetic member 22 are both built into the corresponding first mounting cavity 14 and second mounting cavity 24. That is, the first magnetic member 12 of the first latch assembly 10 is covered and hidden by the first cover member 13, and the second magnetic member 22 of the second latch assembly 20 is covered and hidden by the second cover member 23. This ensures that the first magnetic member 12 and the second magnetic member 22 will not be dislodged by external objects, thus ensuring the mutual magnetic attraction between the first magnetic member 12 of the first latch assembly 10 and the second magnetic member 22 of the second latch assembly 20, and ensuring that the magnetic latch can be properly fastened and used. Furthermore, when the first locking part 112 and the second locking part 212 overlap, the first magnetic member 12 and the second magnetic member 22 magnetically attract each other, enabling the first locking part 112 and the second locking part 212 to be positioned relative to each other. That is, the first fastening structure 113 and the second fastening structure 213 can be positioned relative to each other, and the first fastening structure 113 and the second fastening structure 213 automatically fasten together under the magnetic force of the first magnetic member 12 and the second magnetic member 22. The fastening operation is convenient, accurate, and fast. Moreover, after the first fastening structure 113 and the second fastening structure 213 are fastened together, the first magnetic member 12 and the second magnetic member 22 remain in a magnetically attracted state, thus ensuring that the first fastening structure 113 and the second fastening structure 213 remain in a fastened state.

[0037] In this configuration, both the first magnetic attractor 12 and the second magnetic attractor 22 can be made of magnets, resulting in opposite poles attracting each other. Alternatively, one of the first magnetic attractor 12 and the second magnetic attractor 22 can be a magnet, while the other can be a magnetic material, such as an iron block, in which case the magnet and the magnetic material will attract each other magnetically.

[0038] In the magnetic latch of this embodiment, both the first cover 13 and the second cover 23 can be made of flexible padding; or one of the first cover 13 and the second cover 23 can be made of flexible padding, while the other of the first cover 13 and the second cover 23 can be made of either flexible padding or a rigid material layer. Preferably, both the first cover 13 and the second cover 23 are made of flexible padding. The first cover 13 is bonded to the side of the first latching portion 112 facing the second latching portion 212, and the second cover 23 is bonded to the side of the second latching portion 212 facing the first latching portion 112. The first cover 13 and the second cover 23 come into contact when the first latching portion 112 and the second latching portion 212 overlap. Thus, when the first locking part 112 and the second locking part 212 overlap, they quickly come into contact under the magnetic attraction of the first magnetic member 12 and the second magnetic member 22, that is, the first cover 13 and the second cover 23 quickly come into contact, equivalent to them colliding with each other. Since at least one of the first cover 13 and the second cover 23 is made of a flexible pad, which has the buffering property of elastic deformation, the collision force between the first cover 13 and the second cover 23 is buffered and weakened by the elastic deformation generated by the flexible pad. This allows the first locking part 112 and the second locking part 212 to remain relatively quiet when they are fastened together, reducing the "click" sound emitted when they are fastened together and minimizing the impact on people resting next to the user.

[0039] The flexible padding layer can be made of silicone sheets or felt sheets, which are convenient to select and have low cost.

[0040] like Figures 1 to 5 As shown, the first fastening structure 113 is an insertion hole, and the first cover 13 has a first through hole corresponding to the insertion hole; correspondingly, the second fastening structure 213 is a protrusion protruding along the second direction, and the second cover 23 has a second through hole for the protrusion to pass through. The first fastening assembly 10 is commonly referred to as the female fastener, and the second fastening assembly 20 is commonly referred to as the male fastener. When the first locking part 112 and the second locking part 212 are overlapped, the first magnetic attractant 12 and the second magnetic attractant 22 attract each other, so that the protrusion is inserted into the insertion hole, thus completing the fastening operation and preventing the first fastening structure 113 and the second fastening structure 213 from disengaging along the first direction. Furthermore, as Figures 1 to 5As shown, the insertion hole is a through hole, and the protrusion passes through the through hole, with the end face of the protrusion flush with the outer surface 116 of the first locking part 112. Thus, after the first locking part 112 and the second locking part 212 are engaged, the user can observe the protrusion passing through the through hole, thereby ensuring that the first engaging structure 113 and the second engaging structure 213 are properly, stably, and reliably engaged, reducing the possibility that the first engaging structure 113 and the second engaging structure 213 are not actually engaged.

[0041] like Figures 2 to 4 As shown, the second locking part 212 has two spaced upright plates 214, which extend along a first direction and protrude between the two upright plates 214. The first locking part 112 is confined between the two upright plates 214. Thus, when the first locking part 112 and the second locking part 212 overlap and the first fastening structure 113 and the second fastening structure 213 are fastened together, the first fastening assembly 10 and the second fastening assembly 20 are restricted along the first direction. At the same time, the first fastening assembly 10 is restricted by the two upright plates 214 of the second fastening assembly 20, thereby preventing the first fastening assembly 10 and the second fastening assembly 20 from rotating around the central axis of the protrusion, thus improving the stability and reliability of the magnetic lock.

[0042] To make the overall shape of the second fastener assembly 20 compact and reduce the sharp edges and seams of the second fastener assembly 20, such as... Figure 2 and Figure 3 As shown, the second strap portion 211 is integrally connected to one end of each of the two upright plates 214. That is, there is no seam between the two upright plates 214 and the second strap portion 211. Furthermore, the first buckle body 11 has a first stepped surface 114, and the other end of each upright plate 214 abuts against the first stepped surface 114. This ensures a tight and reliable connection between the first buckle assembly 10 and the second buckle assembly 20 after they are interlocked. And, as... Figure 2 and Figure 3 As shown, the first buckle body 11 also has a second stepped surface 115, and the end of the second buckle portion 212 away from the second strap portion 211 abuts against the second stepped surface 115. Further, as... Figure 1 As shown, the top surface 2140 of the upright plate 214 extending along the first direction is flush with the outer surface 116 of the first latching part 112. Thus, when the first latching assembly 10 and the second latching assembly 20 are fully engaged, the overall shape of the magnetic latch is as follows: Figure 1 The magnetic lock is small and square in shape, and its overall shape is relatively flat and simple. The gap between the first buckle component 10 and the second buckle component 20 is small, which reduces the possibility that the joint edge of the magnetic lock may pinch the user's skin.

[0043] like Figure 5As shown, the second buckle body 21 includes a first shell 216 and a second shell 217. A protrusion is formed on the first shell 216, and a second cover 23 is adhered to the side of the first shell 216 opposite to the second shell 217. The first shell 216 is connected to the second shell 217 to form a second locking portion 212 and a second mounting cavity 24. A second strap portion 211 is formed on the second shell 217. The first shell 216 and the second shell 217 are locked together by screws, resulting in high installation efficiency.

[0044] like Figure 2 , Figure 3 and Figure 5 As shown, the first latch assembly 10 also includes a reinforcing cover plate 117, which is connected to the first latching part 112. The reinforcing cover plate 117 has a clearance space 118. The through hole, the clearance space 118, and the first through hole of the first cover member 13 are arranged opposite to each other. The first cover member 13 is bonded to the reinforcing cover plate 117. The reinforcing cover plate 117 enhances the structural strength of the first latching part 112 and improves the overall reliability of the magnetic latch.

[0045] The first buckle body 11 is a component integrally molded from plastic using an injection molding process. Furthermore, the first shell 216 and the second shell 217 of the second buckle body 21 are also integrally molded from plastic using an injection molding process. The first shell 216 and the second shell 217 are then locked together by screws to form the second buckle part 212.

[0046] According to a second aspect of this application, a neck massage device 100 is provided. For example... Figure 6 As shown, the neck massage device 100 includes a support structure 110 for wearing on a user's neck and a magnetic clasp as described above. Straps 120 are connected to both ends of the support structure 110. A first strap 111 is connected to one of the straps 120, and a second strap 211 is connected to the other strap 120. When the user wears the neck massage device 100, the first buckle assembly 10 and the second buckle assembly 20 are fastened, forming a closed loop around the user's neck with the support structure 110, the two straps 120, and the magnetic clasp. By adjusting the length of the two straps 120, they are kept taut after the first buckle assembly 10 and the second buckle assembly 20 are fastened. At this time, the detachably connected first buckle structure 113 and second buckle structure 213 prevent the first buckle assembly 10 and the second buckle assembly 20 from disengaging in the first direction, thus allowing the neck massage device 100 to be stably worn on the user's neck for massage.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
