[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0027] In the description of this application, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] 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.

[0029] 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.

[0030] On the one hand, combined with Figures 1 to 5 As shown, this embodiment provides a fastening device, which includes a male connector assembly 1 and a female connector assembly 2.

[0031] The male connector assembly 1 includes a male connector body 11 and a fastener 12. The fastener 12 is rotatably arranged on the male connector body 11. The fastener 12 is provided with a limiting head 121, which is non-circular. The female connector assembly 2 is provided with a limiting groove 21. The bottom of the limiting groove 21 and the opening of the limiting groove 21 have different shapes and / or sizes.

[0032] When the buckle 12 is in the first angle range, the limiting head 121 can pass through the opening of the limiting groove 21 and enter or exit the limiting groove 21; when the buckle 12 is in the second angle range, the limiting head 121 cannot pass through the opening of the limiting groove 21 and enter or exit the limiting groove 21.

[0033] The fastening device of this embodiment includes a male connector assembly 1 and a female connector assembly 2. The female connector assembly 2 has a limiting groove 21 with a bottom and an opening of different shapes and / or sizes. The male connector assembly 1 has a latching member 12, which is rotatably arranged. The limiting head 121 of the latching member 12 can pass through the opening of the limiting groove 21 within a first angle range, but cannot pass through the opening of the limiting groove 21 within a second angle range. In use, the latching member 12 is first positioned within the first angle range, allowing the limiting head 121 to pass through the opening of the limiting groove 21 and enter the limiting groove 21. Then, the latching member 12 is rotated to the second angle range, where the limiting head 121 is blocked by the opening of the limiting groove 21 and cannot exit, thus achieving the fastening of the male connector assembly 1 and the female connector assembly 2. When it is necessary to separate the male connector assembly 1 and the female connector assembly 2, it is only necessary to rotate the latching member 12 back to the first angle range.

[0034] The fastening device in this embodiment is simple to operate and has high reliability in fastening connection. Therefore, it can be applied to the disassembly and installation of exoskeleton devices, improving the ease of use of exoskeleton devices.

[0035] In some possible implementations, the first angle range and the second angle range are different rotation angles of the latching member 12 relative to the male head body 11. Figure 4 An example of the fastener 12 being within the first angle range is shown. Figure 3 An example of the snap fastener 12 being in the second angle range is shown.

[0036] For example, when the limiting head 121 is located in the limiting groove 21 and the buckle 12 is within the first angle range, the male head assembly 1 and the female head assembly 2 are in the unlocked state and can be separated.

[0037] When the limiting head 121 is located in the limiting groove 21 and the fastener 12 is in the second angle range, the male head assembly 1 and the female head assembly 2 are locked and cannot be separated.

[0038] In some possible implementations, the bottom of the limiting groove 21 and the opening of the limiting groove 21 have different shapes. For example, the bottom of the limiting groove 21 is circular, and the opening of the limiting groove 21 can be elongated, triangular, or square. At least part of the bottom of the limiting groove 21 is located outside the opening of the limiting groove 21.

[0039] In some possible implementations, the bottom of the limiting groove 21 and the opening of the limiting groove 21 are different in size. For example, the bottom of the limiting groove 21 and the opening of the limiting groove 21 are both circular in shape, and the opening of the limiting groove 21 is the inscribed circle of the bottom of the limiting groove 21. When the limiting head 121 rotates around the eccentric axis, it can rotate outside the opening of the limiting groove 21.

[0040] In some possible implementations, the bottom of the limiting groove 21 and the opening of the limiting groove 21 have different shapes and sizes.

[0041] Combination Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the buckle 12 is in the first angle range, and the orthogonal projection of the limiting head 121 along the axial direction is entirely located inside the opening of the limiting groove 21.

[0042] The latch 12 is in the second angle range, and at least a portion of the orthogonal projection of the limiting head 121 along the axial direction is located outside the opening of the limiting groove 21.

[0043] With the above arrangement, when the buckle 12 is in the first angle range or the second angle range, the relative position of the limiting head 121 and the opening of the limiting groove 21 changes. When the entire orthographic projection of the limiting head 121 is located inside the opening of the limiting groove 21, the limiting head 121 can pass through. However, when a part of the orthographic projection of the limiting head 121 is located outside the opening of the limiting groove 21, the limiting head 121 will be blocked by the opening of the limiting groove 21, so that the limiting head 121 is restricted within the limiting groove 21, thereby fastening the male head assembly 1 and the female head assembly 2 together.

[0044] For example, when the buckle 12 is within the first angle range, the opening angles of the limiting head 121 and the limiting groove 21 are the same.

[0045] For example, the buckle 12 is in the second angle range, and the angles of the limiting head 121 and the opening of the limiting groove 21 are staggered.

[0046] Combination Figure 4 As shown, in some embodiments, the shape of the opening of the limiting groove 21 is the same as the shape of the limiting head 121.

[0047] In this embodiment, the opening of the limiting groove 21 and the limiting head 121 have the same shape. Therefore, when the limiting head 121 is in the first angle range, the angles of the openings of the limiting head 121 and the limiting groove 21 are the same, and the limiting head 121 can pass through the opening of the limiting groove 21. When the limiting head 121 is in the second angle range, the angles of the openings of the limiting head 121 and the limiting groove 21 are staggered, and the limiting head 121 cannot pass through the opening of the limiting groove 21.

[0048] In some possible implementations, the shape of the opening of the limiting groove 21 and the shape of the limiting head 121 can be any one of polygon, ellipse, or cam shape.

[0049] For example, the opening of the limiting groove 21 and the shape of the limiting head 121 are both square.

[0050] Combination Figure 2 and Figure 5 As shown, in some embodiments, the limiting head 121 is provided with a first magnetic component 1211, and the limiting groove 21 is provided with a second magnetic component 222. The first magnetic component 1211 and the second magnetic component 222 are magnetically attracted to each other.

[0051] With the above arrangement, the limiting head 121 and the female head assembly 2 can be magnetically attracted by the first magnetic component 1211 and the second magnetic component 222, which helps to improve the docking efficiency of the male head assembly 1 and the female head assembly 2, and makes the use of the fastening device more convenient.

[0052] Combination Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, the female head assembly 2 includes a female head body 22 and a limiting frame 23.

[0053] The female head body 22 is fixedly connected to the limiting frame 23. The female head body 22 is provided with a groove structure 221, and the limiting frame 23 is provided with an insertion interface 231. The insertion interface 231 communicates with the groove structure 221 to form a limiting groove 21. The insertion interface 231 serves as the opening of the limiting groove 21, and the groove structure 221 serves as the bottom of the limiting groove 21.

[0054] With the above arrangement, the female head assembly 2, which is formed by combining the female head body 22 and the limiting frame 23, has a simpler structure and the limiting groove 21 is easier to process.

[0055] Combination Figure 7 and Figure 8 As shown, in some embodiments, the male connector component 1 further includes a drive button 13.

[0056] The drive button 13 is movably arranged on the male head body 11 along the first direction 001, which is perpendicular to the axis of the buckle 12; the drive button 13 is provided with a rack structure 131, and the buckle 12 is provided with a gear structure 122 arranged coaxially with the limiting head 121.

[0057] The rack structure 131 is meshed with the gear structure 122. The drive button 13 can drive the buckle 12 to rotate through the rack structure 131 and the gear structure 122, so that the buckle 12 can switch between the first angle range and the second angle range.

[0058] With the above arrangement, the drive button 13 can be used to drive the buckle 12 to rotate, control the rotation angle of the buckle 12, and thus control the switching of the locked or unlocked state of the male connector assembly 1 and the female connector assembly 2.

[0059] The drive button 13 is connected to the snap fastener 12 through the rack and pinion structure 131 and the gear structure 122, which is simple in structure and more reliable.

[0060] Combination Figure 5 , Figure 6 and Figure 9 As shown, in some embodiments, the buckle 12 is further provided with a limiting flange 123 arranged coaxially with the gear structure 122, and the limiting flange 123 is located between the limiting head 121 and the gear structure 122.

[0061] The male head body 11 is hollow inside, and a clearance channel 111 is provided on the top of the male head body 11. The gear structure 122 and the limiting flange 123 are located inside the male head body 11, and the size of the limiting flange 123 is larger than the clearance channel 111. The limiting head 121 extends through the clearance channel 111 to the outside of the male head body 11.

[0062] With the above arrangement, the fastener 12 can be reliably rotated within the male head body 11. Moreover, the limiting flange 123 can provide a high-strength supporting force for the limiting head 121, and the limiting head 121 can provide a high-strength supporting force for the female head assembly 2, thereby facilitating the connection strength between the male head assembly 1 and the female head assembly 2.

[0063] See also some possible implementations. Figure 2 , Figure 5 and Figure 6 As shown, the male head body 11 includes a first housing 114 and a second housing 115. The first housing 114 is located on top of the second housing 115, and the clearance channel 111 is located on the first housing 114. The first housing 114 and the second housing 115 form an internal cavity that can be used to accommodate the drive button 13 and the buckle 12.

[0064] For example, at least a portion of the drive button 13 protrudes beyond the side of the male body 11 along the first direction 001, so that the user can apply a pressing force to the drive button 13 to push the drive button 13 to move along the first direction 001.

[0065] For example, refer to Figure 7 As shown, the second housing 115 is provided with a support column 116 arranged along the axial direction of the fastener 12, and the fastener 12 is rotatably sleeved on the support column 116.

[0066] Combination Figure 5 and Figure 6 As shown, in some embodiments, the top of the male head body 11 is provided with a boss structure 112, and the clearance channel 111 is located on the boss structure 112.

[0067] The boss structure 112 and the opening of the limiting groove 21 have the same shape, and the boss structure 112 and the opening of the limiting groove 21 are connected in a limiting manner.

[0068] With the above arrangement, when the male connector 1 and the female connector 2 are fastened together, the openings of the boss structure 112 and the limiting groove 21 are connected to each other. This not only enables the male connector 1 and the female connector 2 to be positioned and docked quickly, but also provides limiting and locking along the mating surface, preventing the male connector 1 and the female connector 2 from being misaligned or rotated relative to each other, thus achieving a better locking effect.

[0069] For example, the openings of the boss structure 112 and the limiting groove 21 are both square in shape.

[0070] Combination Figure 7 and Figure 8 As shown, in some embodiments, the drive button 13 includes a button body 132, a first rod 133 and a second rod 134, the first rod 133 and the second rod 134 are connected to the button body 132 in parallel and at intervals, and extend along the first direction 001 respectively.

[0071] The gear structure 122 is located between the first link 133 and the second link 134, and the rack structure 131 is located on the side of the first link 133 facing the gear structure 122, or on the side of the second link 134 facing the gear structure 122.

[0072] With the above arrangement, the drive button 13 is composed of a button body 132, a first rod 133 and a second rod 134. The gear structure 122 can be accommodated between the first rod 133 and the second rod 134. The buckle 12 and the drive button 13 will not interfere with each other, which can reduce the overall size of the male connector assembly 1. In addition, the rack structure 131 is arranged inside the first rod 133 or inside the second rod 134, which improves the driving stability.

[0073] Combination Figure 7 and Figure 8 As shown, in some embodiments, the first rod 133 has a first limiting structure 1331 at one end of its side facing away from the gear structure 122 along the first direction 001, and a second limiting structure 1332 at the other end. The first limiting structure 1331 and the second limiting structure 1332 are used to abut against the inner wall of the male head body 11 to limit the travel of the drive button 13 along the first direction 001.

[0074] The second rod 134 has a third limiting structure 1341 at one end of its side facing away from the gear structure 122 along the first direction 001, and a fourth limiting structure 1342 at the other end. The third limiting structure 1341 and the fourth limiting structure 1342 are used to abut against the inner wall of the male head body 11 to limit the travel of the drive button 13 along the first direction 001.

[0075] With the above arrangement, the drive button 13 uses the first limiting structure 1331, the second limiting structure 1332, the third limiting structure 1341 and the fourth limiting structure 1342 to achieve travel limit along the first direction 001.

[0076] Combination Figure 7 As shown, in some embodiments, the male connector assembly 1 further includes an elastic element 14, which is connected to the male connector body 11 and the drive button 13 respectively. The elastic element 14 is used to provide an elastic force to the drive button 13 along the first direction 001.

[0077] With the above arrangement, the drive button 13 can move along the first direction 001 using the elastic force provided by the elastic element 14, and obtain a certain elastic pre-tightening force, further simplifying the operation difficulty of the fastening device.

[0078] For example, the elastic element 14 is used to provide the drive button 13 with an elastic force that allows the control latch 12 to rotate from a first angular range toward a second angular range.

[0079] Combination Figure 6 and Figure 7 As shown, in some embodiments, there are two elastic elements 14. The two elastic elements 14 are located on the outside of the first rod 133 facing away from the gear structure 122 and the outside of the second rod 134 facing away from the gear structure 122, respectively, and abut against the first limiting structure 1331 and the third limiting structure 1341 along the first direction 001.

[0080] With the above arrangement, elastic members 14 are respectively arranged on the outer sides of the first rod 133 and the second rod 134, which can provide a balanced elastic force for the drive button 13, and the drive button 13 has better activity characteristics.

[0081] Among some possible implementations, refer to Figure 7 As shown, the dimensions of the first limiting structure 1331 and the third limiting structure 1341 are larger than those of the second limiting structure 1332 and the fourth limiting structure 1342, so that the first limiting structure 1331 can abut against one end of the elastic member 14 along the second direction 002, and the other end of the elastic member 14 abuts against the male head body 11. The third limiting structure 1341 can abut against one end of another elastic member 14 along the second direction 002, and the other end of the elastic member 14 abuts against the male head body 11.

[0082] Combination Figure 2 , Figures 5 to 7 As shown, in some embodiments, the male connector assembly 1 further includes a switch 15, which is movably arranged on the male connector body 11 along a second direction 002, the second direction 002 being parallel to the axial direction of the latching member 12.

[0083] The switch 15 is used to lock the latch 12 within a first angle range when the limit head 121 is not inserted into the limit groove 21.

[0084] With the above arrangement, when the limiting head 121 is not inserted into the limiting groove 21, that is, when the male head assembly 1 and the female head assembly 2 are separated from each other, the buckle 12 can be locked by the switch 15 within the first angle range. At this time, the limiting head 121 can be maintained at an angle that allows it to pass through the opening of the limiting groove 21 and enter and exit the limiting groove 21. The male head assembly 1 and the female head assembly 2 can be directly connected without the need to adjust the angle of the buckle 12.

[0085] Combination Figure 2 , Figure 5 and Figure 10 As shown, in some embodiments, the male connector assembly 1 includes a drive button 13, the drive button 13 includes a limit rod 135, the switch 15 is provided with a limit hook 151, and at least one of the limit rod 135 and the limit hook 151 is provided with a guide slope 1351.

[0086] When the drive button 13 moves toward the switch 15 in the first direction 001, the limit hook 151 moves in the second direction 002 under the action of the guide inclined surface 1351 until the limit rod 135 moves into the limit hook 151, so that the limit hook 151 fixes the limit rod 135, the position of the drive button 13 is locked, and the buckle 12 is locked in the first angle range.

[0087] With the above arrangement, the switch 15 can use the limit hook 151 to hook and fix the limit rod 135, thereby locking the position of the drive button 13. The drive button 13 is connected to the buckle 12 through the rack structure 131 and the gear structure 122. When the position of the drive button 13 is locked, the rotation angle of the buckle 12 will also be locked.

[0088] For example, the guide ramp 1351 is located on the limiting rod 135, and the guide ramp 1351 can drive the limiting hook 151 to move upward.

[0089] When the drive button 13 moves the limit rod 135 toward the switch 15, under the action of the guide slope 1351, the limit hook 151 will move upward along the second direction 002. When the limit hook 151 moves to the top of the limit rod 135, as the limit rod 135 moves further, the limit hook 151 will fall behind the limit rod 135. That is, the limit hook 151 blocks the path of the limit rod 135 moving back, thereby limiting the movement of the limit rod 135.

[0090] Combination Figure 2 , Figure 5 and Figure 8 As shown, in some embodiments, the drive button 13 includes a button body 132, a first rod 133 and a second rod 134. The button body 132 is located at one end of the first rod 133 and the second rod 134 along a first direction 001, and the limiting rod 135 is located at the other end of the first rod 133 and the second rod 134 along the first direction 001, and the limiting rod 135 is perpendicularly connected to the first rod 133 and the second rod 134 respectively.

[0091] With the above arrangement, the button body 132, the first rod 133, the second rod 134 and the limiting rod 135 in the drive button 13 form a frame, which has higher structural strength. The pressing force received by the button body 132 can be simultaneously applied to the limiting rod 135 through the first rod 133 and the second rod 134. The limiting rod 135 moves more smoothly under the action of the two rods.

[0092] Combination Figure 6 , Figure 7 and Figure 10 As shown, in some embodiments, the switch 15 includes two movable bodies 152, which are respectively movably arranged in the switch groove 7 on the male body 11 along the second direction 002, and the limiting hook 151 is connected to the two movable bodies 152 respectively.

[0093] With the above arrangement, the switch 15 can be movably arranged on the male connector body 11 using the movable body 152, and can move along the second direction 002, thus having better mobility.

[0094] Combination Figure 11 As shown, in some embodiments, the switch 15 is provided with a third magnetic component 153, the female connector assembly 2 is provided with a fourth magnetic component 24, and the male connector body 11 is provided with a fifth magnetic component 113. The third magnetic component 153 is magnetically attracted to the fourth magnetic component 24 and the fifth magnetic component 113 respectively, and the magnetic force between the third magnetic component 153 and the fourth magnetic component 24 is greater than the magnetic force between the third magnetic component 153 and the fifth magnetic component 113.

[0095] With the above arrangement, the switch 15 can achieve relative attraction with the female connector assembly 2 using the third magnetic component 153 and the fourth magnetic component 24, moving towards the side where the female connector assembly 2 is located. It can also achieve mutual attraction with the male connector body 11 using the third magnetic component 153 and the fifth magnetic component 113, moving towards the side where the male connector body is located. This achieves reciprocating movement control of the switch 15 along the second direction 002. In addition, since the magnetic force of the female connector assembly 2 on the switch 15 is large, when the male connector assembly 1 and the female connector assembly 2 are fastened together, the switch 15 will move towards the female connector assembly 2. This will cause the limit hook 151 and the limit rod 135 to disengage, the drive button 13 will be unlocked, and the drive button 13 will move under the action of the elastic component 14, driving the buckle 12 to rotate from the first angle range to the second angle range, thereby locking the male connector assembly 1 and the female connector assembly 2. When the male connector assembly 1 and the female connector assembly 2 are separated, the switch 15 will move toward the male connector body 11, which will cause the limit hook 151 and the limit rod 135 to hook together, and the drive button 13 will be locked.

[0096] Combination Figure 12 As shown, in some embodiments, the switch 15 is provided with a third magnetic component 153 and a sixth magnetic component 154, the female connector assembly 2 is provided with a fourth magnetic component 24, and the male connector body 11 is provided with a fifth magnetic component 113. The third magnetic component 153 and the fourth magnetic component 24 are magnetically attracted, and the sixth magnetic component 154 and the fifth magnetic component 113 are magnetically attracted. Moreover, the magnetic force between the third magnetic component 153 and the fourth magnetic component 24 is greater than the magnetic force between the sixth magnetic component 154 and the fifth magnetic component 113.

[0097] Through the above arrangement, the switch 15 can achieve relative attraction with the female connector assembly 2 using the third magnetic component 153 and the fourth magnetic component 24, moving towards the side where the female connector assembly 2 is located. It can also achieve mutual attraction with the male connector body 11 using the sixth magnetic component 154 and the fifth magnetic component 113, moving towards the side where the male connector body is located. This achieves reciprocating movement control of the switch 15 along the second direction 002. Furthermore, because the female connector assembly 2 exerts a large magnetic force on the switch 15, when the male connector assembly 1 and the female connector assembly 2 are engaged, the switch 15 will move towards the female connector assembly 2. This will cause the limiting hook 151 and the limiting rod 135 to disengage, unlocking the drive button 13. The drive button 13 then moves under the action of the elastic component 14, driving the latching component 12 to rotate from the first angle range to the second angle range, thus locking the male connector assembly 1 and the female connector assembly 2. When the male connector assembly 1 and the female connector assembly 2 are separated, the switch 15 will move toward the male connector body 11, which will cause the limit hook 151 and the limit rod 135 to hook together, and the drive button 13 will be locked.
