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.

[0054] 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.

[0055] 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.

[0056] On the one hand, combined with Figures 1 to 4As shown, this embodiment provides a fastening device, which includes a fastening member 1 and a fastening box 2. The fastening member 1 is provided with a claw portion 11; the fastening box 2 is hollow inside, and the top of the fastening box 2 is provided with an insertion interface 20a; the fastening box 2 is provided with a fastening member 21 and a limiting member 22, which are movably arranged respectively.

[0057] The fastening device has a fastened state and a disengaged state.

[0058] In the latching state, the latching member 1 is attached to the top surface of the latching box 2, and the claw portion 11 is inserted into the insertion interface 20a; the latching member 21 is located in the first position and is separated from the limiting member 22. The orthographic projection of the latching member 21 along the latching direction 002 at least partially coincides with the orthographic projection of the claw portion 11 along the latching direction 002, and a latching force is applied to the claw portion 11 toward the inside of the latching box 2.

[0059] In the separated state, the fastener 1 is separated from the top surface of the fastener box 2; the latch 21 is in the second position and is limited and connected to the limiting member 22. The orthographic projection of the latch 21 along the fastening direction 002 does not coincide with the orthographic projection of the claw part 11 along the fastening direction 002.

[0060] In this embodiment of the fastening device, the claw portion 11 of the fastening member 1 can be inserted into the fastening box 2. After the fastening member 21 moves to the first position, at least a part of the fastening member 21 moves above the claw portion 11, which can apply an inward fastening force to the claw portion 11, thereby realizing the fastening connection between the fastening member 1 and the fastening box 2. After the fastening member 21 moves to the second position, the fastening member 21 and the claw portion 11 do not overlap, and the claw portion 11 can be inserted or withdrawn from the fastening box 2. Moreover, the position of the fastening member 21 is restricted by the limiting member 22, which facilitates the next insertion and fastening of the claw portion 11.

[0061] In this embodiment, in the latching state, the orthographic projection of the latching member 21 along the latching direction 002 at least partially overlaps with the orthographic projection of the claw portion 11 along the latching direction 002. That is, the latching member 21 and the claw portion 11 have partially overlapping structures in the latching direction 002, so the latching member 21 can apply a latching force toward the inside of the latching box 2 to the claw portion 11. In the disengaged state, the orthographic projection of the latching member 21 along the latching direction 002 does not overlap with the orthographic projection of the claw portion 11 along the latching direction 002. That is, when the claw portion 11 moves along the latching direction 002, it will not be blocked by the latching member 21, so the claw portion 11 can extend into or exit from the latching box 2.

[0062] Combination Figures 3 to 6As shown, in some embodiments, the claw portion 11 includes a limiting head 111 and a connecting neck 112. The outer diameter of the limiting head 111 is larger than the outer diameter of the connecting neck 112. The connecting neck 112 is connected to the surface of the fastener 1 facing the fastener box 2, and the limiting head 111 is located at the end of the connecting neck 112 facing away from the fastener 1.

[0063] The fastener 21 includes a first limiting hole 211, the inner diameter of which is greater than the outer diameter of the connecting neck 112 and less than the outer diameter of the limiting head 111.

[0064] When the buckle 21 is in the first position, the connecting neck 112 is located inside the first limiting hole 211, and the limiting head 111 is located below the first limiting hole 211. The orthographic projection of the buckle 21 around the first limiting hole 211 along the fastening direction 002 at least partially coincides with the orthographic projection of the limiting head 111 along the fastening direction 002, and a fastening force towards the inside of the fastening box 2 is applied to the limiting head 111.

[0065] With the above arrangement, when the buckle 21 is in the first position, the buckle 21 can accommodate the connecting neck 112 through the first limiting hole 211. The limiting head 111 is located below the first limiting hole 211, so the buckle 21 can limit and block the limiting head 111, thereby playing the role of retracting the fastener 1 and fastening it on the fastener box 2.

[0066] Among some possible implementations, refer to Figure 3 and Figure 4 As shown, the limiting head 111 and the connecting neck 112 are integral structures, and / or, the claw portion 11 and the remaining part of the fastener 1 are integral structures. For example, the fastener 1 is a die-cast structural part.

[0067] In some possible implementations, the first limiting hole 211 is connected to one side edge of the fastener 21, and the limiting head 111 can move to the outside of the fastener 21 and below the fastener 21. When the fastener 21 moves, the connecting neck 112 enters the first limiting hole 211 from the edge of the fastener 21. At the same time, the limiting head 111 moves to the bottom of the first limiting hole 211.

[0068] Combination Figures 3 to 6 As shown, in some embodiments, the buckle 21 further includes a second limiting hole 212, the inner diameter of which is larger than the outer diameter of the limiting head 111, and the second limiting hole 212 is connected to the first limiting hole 211.

[0069] When the buckle 21 is in the second position, the second limiting hole 212 is aligned with the limiting head 111. The orthographic projection of the limiting head 111 along the fastening direction 002 is located within the orthographic projection range of the second limiting hole 212 along the fastening direction 002, and the limiting head 111 can pass through the second limiting hole 212.

[0070] With the above arrangement, the fastener 21 has a second limiting hole 212 with an inner diameter larger than that of the limiting head 111. The limiting head 111 can move through the second limiting hole 212 to the bottom of the fastener 21. Then, through the movement of the fastener 21, the limiting head 111 moves to the bottom of the first limiting hole 211, thereby blocking and limiting the limiting head 111. When it is necessary to release the blocking and limiting, the fastener 21 moves in the opposite direction, causing the limiting head 111 to move to the bottom of the second limiting hole 212, and can then exit from the second limiting hole 212, realizing the separation of the fastener 1 and the fastener box 2.

[0071] Combination Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments, the limiting member 22 is located below the fastening member 21. In the fastened state, the limiting member 22 moves downward and separates from the fastening member 21; in the separated state, the limiting member 22 moves upward and is limitedly connected to the fastening member 21.

[0072] With the above arrangement, the limiting member 22 can lock and unlock the position of the buckle member 21 by moving up and down.

[0073] Combination Figure 8 As shown, in some embodiments, the snap-fit ​​box 2 is further provided with a second elastic member 23. The second elastic member 23 is connected to the snap-fit ​​box 2 and the limiting member 22 respectively. The second elastic member 23 is used to provide the limiting member 22 with an elastic force that moves along the snap-fit ​​direction 002.

[0074] With the above arrangement, the second elastic element 23 can provide an elastic force to the limiting element 22, and the limiting element 22 can achieve semi-automatic movement by utilizing the elastic force of the second elastic element 23.

[0075] In some possible implementations, the second elastic member 23 is located below the limiting member 22 and is supported between the inner wall of the snap-fit ​​box 2 and the limiting member 22. The second elastic member 23 can apply an elastic force outward along the snap-fit ​​direction 002 to the limiting member 22. Under the elastic force of the second elastic member 23, the limiting member 22 can move toward the snap fastener 21, so that the limiting member 22 maintains the position and state of being limitedly connected with the snap fastener 21.

[0076] Combination Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, in some embodiments, the snap-fit ​​box 2 is provided with a second limiting post 25, the axis of the second limiting post 25 is parallel to the snap-fit ​​direction 002, and the limiting member 22 is provided with a third limiting hole 221, which is slidably connected to the second limiting post 25.

[0077] With the above arrangement, the limiting member 22 can achieve up-and-down movement guidance and limitation through the sliding cooperation of the second limiting post 25 and the third limiting hole 221.

[0078] Among some possible implementations, refer to Figure 3 and Figure 4 As shown, there are two first limiting posts 214 and two third limiting holes 221. The two first limiting posts 214 are arranged symmetrically, and the two third limiting holes 221 are arranged symmetrically on the limiting member 22. The first limiting posts 214 and the third limiting holes 221 are slidably connected in a one-to-one correspondence.

[0079] In some possible implementations, the second elastic element 23 is a helical spring, which is sleeved on the first limiting post 214. The first limiting post 214 can be used to install and fix the helical spring and provide guidance and limitation for the helical spring.

[0080] Combination Figure 7 As shown, in some embodiments, the limiting member 22 is provided with a first limiting structure 222, and the fastening member 21 is provided with a second limiting structure 213. The first limiting structure 222 and the second limiting structure 213 abut against each other along the first direction 001 so that the limiting member 22 and the fastening member 21 are limitedly connected.

[0081] With the above arrangement, the limiting member 22 can be limited and connected with the buckle member 21 by the first limiting structure 222 and the second limiting structure 213, so that the buckle member 21 is limited and fixed in the second position.

[0082] Combination Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the top surface inside the snap-fit ​​box 2 is provided with at least two first magnetic elements 26, the magnetic pole directions of the at least two first magnetic elements 26 are different, and the snap-fit ​​member 1 is provided with at least two second magnetic elements 13 facing the surface of the snap-fit ​​box 2, the magnetic pole directions of the at least two second magnetic elements 13 are different, and each second magnetic element 13 is magnetically attracted to one of the first magnetic elements 26.

[0083] With the above arrangement, when the fastening member 1 and the fastening box 2 approach each other, due to the mutual attraction of the first magnetic member 26 and the second magnetic member 13, the claw part 11 extends into the fastening box 2 and presses down against the limiting member 22, causing the limiting member 22 to separate from the fastening member 21. The fastening member 21 can move from the second position to the first position, thereby causing the limiting head 111 of the claw part 11 to move below the first limiting hole 211 and be blocked and locked by the first limiting hole 211. Thus, the first magnetic member 26 and the second magnetic member 13 can realize the automatic unlocking of the limiting member 22, and can also realize the magnetic positioning of the claw part 11 and the insertion interface 20a, realizing foolproof insertion and further improving the ease of use of the fastening device.

[0084] In some possible implementations, the first magnetic element 26 and the second magnetic element 2 are strip magnets, respectively.

[0085] Combination Figure 3 As shown, in some embodiments, the first magnetic element 26 is located inside the snap-fit ​​box 2, below the limiting element 22, and fixedly connected to the inner wall of the snap-fit ​​box 2. At least a portion of the claw portion 11 is ferromagnetic and can be magnetically attracted by the first magnetic element 26; in the snap-fit ​​state, the first magnetic element 26 and the claw portion 11 attract each other, and the claw portion 11 applies a downward pressure on the limiting element 22 to separate the limiting element 22 and the snap-fit ​​element 21.

[0086] In some possible implementations, at least a portion of the claw portion 11 is ferromagnetic. This could be because the claw portion 11 is supported by a ferromagnetic material, a portion of the structure of the claw portion 11 is supported by a ferromagnetic material, or a ferromagnetic material or magnet is embedded on or inside the surface of the claw portion 11.

[0087] Among some possible implementations, refer to Figure 3 and Figure 4 As shown, the limiting member 22 is provided with a clearance hole 223, and at least a portion of the locking part can pass through the clearance hole 223 to contact and adsorb with the magnetic member 26.

[0088] Combination Figure 3 and Figure 4 As shown, in some embodiments, the fastener 21 is movably arranged along the first direction 001, and the fastener 21 moves along the first direction 001 to switch between the first position and the second position. The first direction 001 is perpendicular to the fastening direction 002 of the fastener 1; the limiting member 22 is movably arranged along the fastening direction 002.

[0089] With the above arrangement, the latch 21 can switch between a first position and a second position along the first direction 001, thereby blocking and locking the claw part 11 in the first position and unlocking the claw part 11 in the second position.

[0090] Combination Figure 5 and Figure 8 As shown, in some embodiments, the inner wall of the snap-fit ​​box 2 is provided with a limiting groove 27 arranged along the first direction 001, and the snap fastener 21 is provided with a first limiting post 214, which is slidably arranged in the limiting groove 27.

[0091] With the above arrangement, the first limiting post 214 and the limiting groove 27 can provide guidance and limitation for the buckle 21 when it moves in the first direction 001, so that the buckle 21 can accurately reach the first position or the second position.

[0092] Combination Figure 3 and Figure 8 As shown, in some embodiments, the snap-fit ​​box 2 is further provided with a first elastic element 24, which is connected to the snap-fit ​​box 2 and the snap fastener 21 respectively. The first elastic element 24 is used to provide the snap fastener 21 with an elastic force that moves along the first direction 001.

[0093] With the above arrangement, the first elastic element 24 can provide an elastic force to the buckle 21, and the buckle 21 can achieve semi-automatic movement by utilizing the elastic force of the first elastic element 24.

[0094] In some possible implementations, the fastener 21 is also provided with a guide post (not shown in the figure), the axis of the guide post is parallel to the first direction 001, the first elastic member 24 is sleeved on the guide post, and the guide post provides installation and limiting guidance for the first elastic member 24.

[0095] Combination Figure 3 and Figure 8 As shown, in some embodiments, the snap-fit ​​box 2 has a pressing opening 20b on one side along the first direction 001, and the snap fastener 21 is inserted into the snap-fit ​​box 2 through the pressing opening 20b. When the snap fastener 21 is in the first position, at least a portion of the snap fastener 21 protrudes to the outside of the pressing opening 20b.

[0096] With the above arrangement, when the buckle 21 is in the first position, that is, when the fastening device is in the fastening state, at least a part of the buckle 21 can protrude to the outside of the fastening box 2. The buckle 21 can be moved from the first position to the second position by external force pressing, thereby controlling the buckle 21 to release the limiting lock on the claw part 11, so that the fastening device can be separated.

[0097] Combination Figure 5 and Figure 8 As shown, in some embodiments, when the buckle 21 includes a first limiting hole 211 and a second limiting hole 212, the first limiting hole 211 and the second limiting hole 212 are arranged along a first direction 001.

[0098] When the buckle 21 is in the first position, the axis of the first limiting hole 211 coincides with the axis of the claw portion 11; when the buckle 21 is in the second position, the axis of the second limiting hole 212 coincides with the axis of the claw portion 11.

[0099] With the above arrangement, the buckle 21 can block and limit the buckle part by using the first limiting hole 211 when it is in the first position, and can release the buckle part by using the second limiting hole 212 when it is in the second position, so as to realize the buckling and separation of the buckle 1 and the buckle box 2.

[0100] Combination Figure 5 and Figure 6 As shown, in some embodiments, the insertion interface 20a is a polygonal opening, and the surface of the fastener 1 facing the fastener box 2 is provided with an insertion boss 12, which has the same shape as the insertion interface 20a; in the fastening state, at least a portion of the insertion boss 12 is inserted into the insertion interface 20a.

[0101] With the above arrangement, after the insertion interface 20a and the fastening boss are connected, the circumferential position of the fastening piece 1 and the fastening box 2 is locked. Thus, the fastening device can not only limit the planar position of the fastening piece 1 and the fastening box 2, but also limit the circumferential position.

[0102] On the other hand, this application provides an exoskeleton device, which includes the fastening device of this application.
