[0058] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0059] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0060] On the one hand, combined with Figures 1 to 4 , Figure 7 and Figure 8 As shown, this embodiment provides a fastening device, which includes a male fastening component 1 and a female fastening component 2.

[0061] The male buckle assembly 1 includes a male buckle body 11, at least one movable buckle 12, and a drive member 16.

[0062] The driving member 16 has a ring structure and is rotatably arranged on the male buckle body 11. At least one movable buckle 12 is located inside the driving member 16 and is movably connected to the male buckle body 11. The at least one movable buckle 12 includes a snap-on position and a snap-off position that can be switched between each other.

[0063] When the drive member 16 rotates, the drive member 16 can drive at least one movable latch 12 to move from the latching position to the unlocking position.

[0064] The female buckle assembly 2 includes a female buckle body 21, and the female buckle body 21 is provided with at least one slot portion 211.

[0065] When at least one movable latch 12 is in the latching position, at least a portion of the at least one movable latch 12 extends into at least one latching slot 211, and the male latch assembly 1 and the female latch assembly 2 are latched together; when at least one movable latch 12 is in the unlocking position, the entire at least one movable latch 12 is outside the at least one latching slot 211, and the male latch assembly 1 and the female latch assembly 2 are disengaged from each other.

[0066] The fastening device of this embodiment has a male fastening component 1 and a female fastening component 2. The male fastening component 1 has a movable buckle 12 and a driving member 16. The driving member 16 is rotatably arranged and can drive the movable buckle 12 from the engaging position to the disengaged position by its own rotation. When the movable buckle 12 is in the engaging position, it can engage with the slot 211 of the female fastening component 2, so that the male fastening component 1 and the female fastening component 2 are fastened together. When the movable buckle 12 is in the disengaged position, it can disengage from the slot 211 of the female fastening component 2, so that the male fastening component 1 and the female fastening component 2 are disengaged. Thus, the position of the movable buckle 12 can be controlled by rotating the driving member 16, so as to realize quick disassembly and quick assembly of the male fastening component 1 and the female fastening component 2. This can be applied to the disassembly and assembly of exoskeleton devices, improving the ease of use of exoskeleton devices.

[0067] In some possible implementations, the number of movable clips 12 can be one, two, three, etc. When the number of movable clips 12 is two or more, the two or more movable clips 12 can be arranged in different directions, for example, two movable clips 12 can be arranged back to back, or three movable clips 12 can be arranged back to back in a triangular shape.

[0068] Combination Figure 2 , Figures 6 to 8 As shown, in some embodiments, the inner wall of the drive member 16 is provided with at least one pressing boss 161.

[0069] When the drive member 16 rotates, at least one pressing boss 161 can press at least one movable latch 12 inward, so that at least one movable latch 12 moves from the engaged position to the disengaged position.

[0070] With the above arrangement, the driving component 16 can use the pressing boss 161 on the inner wall to press and drive the movable buckle 12, which has a simple structure and more reliable driving performance.

[0071] In some possible implementations, the pressing boss 161 includes a guide slope, and when the movable latch 12 contacts the pressing boss 161, the movable latch 12 can slide along the guide slope and be gradually pressed inward.

[0072] In some possible implementations, the number of abutment bosses 161 can be one, two, three, etc. When the number of abutment bosses 161 is two or more, the abutment bosses 161 are arranged circumferentially at intervals along the inner wall of the drive member 16.

[0073] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the male fastener assembly 1 further includes at least one first elastic element 15.

[0074] At least one first elastic element 15 is connected to at least one movable buckle 12 and male buckle body 11 respectively. The at least one first elastic element 15 is used to provide an elastic force to at least one movable buckle 12 so that at least one movable buckle 12 can move from the unlocked position to the engaged position.

[0075] With the above arrangement, the movable buckle 12 can move from the unlocking position to the engaging position using the first elastic member 15, so as to realize the mutual engagement of the male buckle assembly 1 and the female buckle assembly 2. Furthermore, the first elastic member 15 can apply a certain elastic preload to the movable buckle 12 in the engaging position to ensure the engagement stability of the movable buckle 12 and the slot portion 211.

[0076] Combination Figure 2 and Figure 7 As shown, in some embodiments, there are two movable latches 12, which are back to back and arranged along a diameter line of the drive member 16.

[0077] There are two first elastic elements 15. Each first elastic element 15 is connected to a movable buckle 12 and a male buckle body 11 respectively. The first elastic element 15 can provide a radially outward elastic force to the corresponding movable buckle 12.

[0078] There are two abutment protrusions 161, with each movable buckle 12 corresponding to one abutment protrusion 161. The abutment protrusion 161 can provide a radially inward abutment force to the corresponding movable buckle 12.

[0079] With the above arrangement, the male buckle assembly 1 and the female buckle assembly 2 can be connected by two movable buckles 12, resulting in higher connection reliability.

[0080] Combination Figure 6 and Figure 8 As shown, in some embodiments, the male buckle assembly 1 further includes at least one second elastic member 17, which is connected to the driving member 16 and the male buckle body 11 respectively. The at least one second elastic member 17 is used to provide an elastic force to the driving member 16 so that the position of at least one pressing boss 161 is circumferentially offset from that of at least one movable buckle 12.

[0081] With the above arrangement, after the rotating drive member 16 drives the movable buckle 12 from the engaging position to the disengaged position, the drive member 16 needs to be restored so that the position of the pressing boss 161 and the movable buckle 12 is misaligned, so as not to affect the next engagement of the male buckle assembly 1 and the female buckle assembly 2. Therefore, a second elastic member 17 is arranged between the male buckle body 11 and the drive member 16. The elastic force of the second elastic member 17 is used to drive the drive member 16 to rotate in the opposite direction, so that the drive member 16 rotates and resets.

[0082] Among some possible implementations, refer to Figures 6 to 9 As shown, the locking groove 162 is located on the axial end face of the driving member 16 facing the female buckle assembly 2. The driving member 16 has at least one hollowed-out groove 163 on the axial end face facing away from the female buckle assembly 2. A first connecting post 163a is provided in the hollowed-out groove 163, and a second connecting post 111b is provided on the male buckle body 11 at the corresponding position. The second connecting post 111b can extend into the hollowed-out groove 163. The second elastic member 17 is arranged in the hollowed-out groove 163 and is connected to the first connecting post 163a and the second connecting post 111b respectively, thereby realizing the elastic connection between the driving member 16 and the male buckle body 11.

[0083] Combination Figure 6 and Figure 9 As shown, in some embodiments, the male buckle body 11 is provided with at least two limiting posts 18, the at least two limiting posts 18 are arranged at intervals along the circumference of the driving member 16, the driving member 16 is rotatably sleeved on the at least two limiting posts 18, and the outer peripheral wall of the at least two limiting posts 18 is rotatably connected to the inner peripheral wall of the driving member 16.

[0084] At least two limiting posts 18 are provided with limiting structures 181 respectively. The position of the limiting structure 181 corresponds to the position of the pressing protrusion. The limiting structure 181 provides rotation limit for the driving member 16.

[0085] By using at least two limiting posts 18 arranged on the male buckle body 11, the drive member 16 can be rotated. Moreover, compared with the ordinary rotating shaft structure, the limiting posts 18 can free up space at the axis position of the drive member 16 for arranging components such as the movable buckle 12, the first elastic member 15, and the limit switch 13, which is beneficial to improving the structural compactness of the male buckle assembly 1.

[0086] Combination Figure 6 and Figure 9 As shown, in some embodiments, the male buckle body 11 is provided with at least two limiting posts 18, which are arranged at intervals along the circumference of the driving member 16. The driving member 16 is rotatably sleeved on the at least two limiting posts 18, and the outer peripheral walls of the at least two limiting posts 18 are rotatably connected to the inner peripheral walls of the driving member 16. The limit switch 13 includes a movable body 133, which is located between the at least two limiting posts 18. The at least two limiting posts 18 provide limiting and movement guidance for the movable body 133, and at least one locking part 132 is connected to the movable body 133.

[0087] With the above arrangement, at least two limit posts 18 can not only limit the rotation of the drive component 16, but also limit the movement of the limit switch 13, resulting in a simpler and more compact structure.

[0088] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the male buckle assembly 1 further includes a limit switch 13, which is movably arranged along a first direction and can lock at least one movable buckle 12 in the unlocked position; the first direction is the buckling direction of the male buckle assembly 1 and the female buckle assembly 2.

[0089] The limit switch 13 includes a first magnetic element 131 and a second magnetic element 22 on the female buckle body 21. The first magnetic element 131 and the second magnetic element 22 are magnetically attracted or repelled.

[0090] When the male buckle assembly 1 and the female buckle assembly 2 approach each other along the first direction, the first magnetic element 131 and the second magnetic element 22 interact to drive the limit switch 13 to move, so that the limit switch 13 releases the lock on at least one movable buckle 12, and at least one movable buckle 12 can move from the unlocked position to the engaged position.

[0091] With the above arrangement, when the male buckle assembly 1 and the female buckle assembly 2 approach each other, the limit switch 13 can be driven by the magnetic force between the first magnetic element 131 and the second magnetic element 22 to release the lock on the movable buckle 12, so that the movable buckle 12 can move from the unlocked position to the engaged position, and the male buckle assembly 1 and the female buckle assembly 2 are fastened together. This realizes the automatic unlocking of the limit switch 13 without additional operation, and further improves the efficiency of the fastening device.

[0092] The fastening device of this embodiment has a male fastening component 1 and a female fastening component 2. The male fastening component 1 has a movable buckle 12 and a limit switch 13. When the movable buckle 12 is in the engaging position, it can engage with the slot 211 of the female fastening component 2, so that the male fastening component 1 and the female fastening component 2 are fastened together. When the movable buckle 12 is in the disengaged position, it can disengage from the slot 211 of the female fastening component 2, so that the male fastening component 1 and the female fastening component 2 are disengaged. Thus, by controlling the position of the movable buckle 12, the male fastening component 1 and the female fastening component 2 can be quickly disassembled and installed. This can be applied to the disassembly and installation of exoskeleton devices, improving the ease of use of exoskeleton devices.

[0093] Furthermore, in this embodiment, after the movable latch 12 moves to the unlocked position, the position of the movable latch 12 can be locked by the limit switch 13, preventing the movable latch 12 from moving arbitrarily to the locked position. Otherwise, the position of the movable latch 12 would need to be adjusted to the unlocked position before the next fastening operation. By locking the movable latch 12 in the unlocked position using the limit switch 13, the male latch assembly 1 and the female latch assembly 2 can be directly fastened together during the next fastening operation, which improves the ease of use and efficiency of the fastening device.

[0094] In some possible implementations, when the limit switch 13 locks the movable latch 12 in the unlocked position, the limit switch 13 and the movable latch 12 can be in direct contact or indirectly connected.

[0095] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the male buckle body 11 is provided with a third magnetic element 14, and the third magnetic element 14 and the first magnetic element 131 are magnetically attracted or repelled.

[0096] When the male buckle assembly 1 and the female buckle assembly 2 move away from each other along the first direction, the third magnetic element 14 and the first magnetic element 131 interact to drive the limit switch 13 to move, so that the limit switch 13 locks at least one movable buckle 12 in the unlocked position.

[0097] With the above arrangement, when the movable buckle 12 moves to the unlocking position and the male buckle component 1 and the female buckle component 2 move away from each other, the limit switch 13 can be driven by the magnetic force between the first magnetic component 131 and the third magnetic component 14 to lock the position of the movable buckle 12, so that the movable buckle 12 will not move randomly. Only when the female buckle component 2 moves closer again can the limit switch 13 be driven in the opposite direction by the magnetic force of the second magnetic component 22 to unlock the position of the movable buckle 12.

[0098] Combination Figure 3 and Figure 4 As shown, in some embodiments, the second magnetic element 22, the first magnetic element 131 and the third magnetic element 14 are arranged sequentially along a first direction, and the second magnetic element 22 and the first magnetic element 131 are magnetically attracted to each other, and the third magnetic element 14 and the first magnetic element 131 are magnetically attracted to each other.

[0099] With the above arrangement, the second magnetic component 22 can attract the first magnetic component 131 to move the limit switch 13 toward the side where the female buckle assembly 2 is located, thereby releasing the position lock of the movable buckle 12. The third magnetic component 14 can attract the first magnetic component 131 to move the limit switch 13 toward the side where the male buckle assembly 1 is located, thereby locking the position of the movable buckle 12.

[0100] In some embodiments, the magnetic force exerted by the second magnetic element 22 on the first magnetic element 131 is greater than the magnetic force exerted by the third magnetic element 14 on the first magnetic element 131.

[0101] With the above arrangement, when the female buckle assembly 2 is not close, the first magnetic element 131 is attracted by the third magnetic element 14, and the limit switch 13 is magnetically attracted to the locked state. When the female buckle assembly 2 is close, the first magnetic element 131 is attracted by the second magnetic element 22, and the limit switch 13 is magnetically attracted to the unlocked state. By arranging the magnetic strength of the second magnetic element 22 and the third magnetic element 14, the limit switch 13 can be automatically unlocked when the female buckle assembly 2 is close and automatically locked when the female buckle assembly 2 is far away.

[0102] Combination Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, the limit switch 13 is located inside the drive member 16, the limit switch 13 includes at least one latching part 132, and the drive member 16 is provided with at least one latching groove 162.

[0103] When at least one movable latch 12 is in the unlocked position, at least one locking part 132 enters at least one locking groove 162, thereby locking the circumferential position of the drive member 16, and at least one pressing boss 161 presses at least one movable latch 12 to hold it in the engaged position.

[0104] With the above arrangement, the limit switch 13 can lock the rotation position of the drive member 16 by using the latching part 132 and the latching groove 162 on the drive member 16, and lock the drive member 16 in the position where the pressing boss 161 and the movable buckle 12 are pressed together, so that the movable buckle 12 is kept in the unlocked position, thereby realizing the locking of the position of the movable buckle 12.

[0105] In some possible implementations, the locking groove 162 is located on the axial end face of the drive member 16 facing the female buckle assembly 2. When the limit switch 13 moves toward the side where the female buckle assembly 2 is located, the locking part 132 disengages from the locking groove 162. The locking part 132 is located outside the axial end face of the drive member 16, and the drive member 16 can rotate. When the limit switch 13 moves toward the side where the male buckle assembly 1 is located, the locking part 132 is inserted into the locking groove 162 axially, and the drive member 16 cannot rotate, thereby locking the position of the movable buckle 12.

[0106] Combination Figure 6 and Figure 9 As shown, in some embodiments, the male buckle body 11 includes a bottom shell 111 and a top cover 112. The bottom shell 111 has a top-open receiving cavity 111a for accommodating at least one movable buckle 12 and a limit switch 13.
