[0023] Figure 2 is a schematic diagram of the connection between the arc-shaped connecting plate and the glove shown in the present utility model;

[0026] To better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.

[0027] Combined with Figure 1 shown, when a patient usually performs hand rehabilitation training, the hand needs to wear the glove 20. Through the glove 20, the hand and the hand exoskeleton 100 are coupled, and the hand exoskeleton 100 drives the hand to complete the rehabilitation training actions. It can be seen that the glove 20 is an important factor in realizing the coupling between the patient's hand and the hand exoskeleton 100, and is also a necessity for realizing the rehabilitation training. Therefore, when it is necessary to replace the glove or the phalanx parts of the hand exoskeleton, whether the glove 20 and the hand exoskeleton 100 can be easily disassembled and assembled becomes particularly important.

[0028] As Figure 1-2 shown, a first aspect of the present utility model provides a quick installation device for a hand joint activity instrument glove, including an arc-shaped connecting plate 10 and a glove 20. There are multiple arc-shaped connecting plates 10, which are respectively connected to corresponding positions of the hand exoskeleton 100 and can be driven by the hand exoskeleton 100 to move to a predetermined position.

[0029] Combined with Figure 2 and Figure 4 shown, one side of each arc-shaped connecting plate 10 away from the arc-shaped groove 101 is connected to the hand exoskeleton 100. The multiple arc-shaped connecting plates 10 are independent of each other, and an arc-shaped groove 101 is provided on the inner side of each arc-shaped connecting plate 10.

[0030] The glove 20 includes multiple phalanx structures, and the phalanx structures can be placed in the corresponding arc-shaped grooves 101. A snap ring 21 is provided on the outer wall of each phalanx structure. In this way, the connection between the glove phalanx structure and the arc-shaped connecting plate 10 is realized through the snap ring 21. When each arc-shaped connecting plate 10 is driven by the hand exoskeleton 100 to move, the corresponding glove phalanx structure connected by the snap ring 21 also moves correspondingly, and the hand of the patient wearing the glove can perform corresponding rehabilitation training actions.

[0031] Combined with Figure 2-4 shown, a clamping structure 11 is provided on the outer side of the arc-shaped connecting plate 10, and a through hole is provided on the arc-shaped connecting plate 10. The snap ring 21 can pass through the through hole and be connected to the clamping structure 11 and be limited, so that the phalanx structure is kept connected to the corresponding arc-shaped groove 101.

[0032] Thus, after the snap ring 21 passes through the perforation and is limited by the snap connection structure 11, the snap ring 21 and the arc-shaped connecting plate 10 are in a relatively fixed state. At this time, the knuckle structure also remains relatively fixed with the arc-shaped connecting plate 10. Meanwhile, when the snap ring 21 is disconnected from the snap connection structure 11, the knuckle structure can be separated from the corresponding arc-shaped connecting plate 10.

[0033] In an alternative embodiment, in order to ensure the stable connection and limitation of the knuckle structure, snap rings 21 are respectively provided on both sides of the knuckle structure, and a pair of snap connection structures 11 are provided on the outer side of the arc-shaped connecting plate 10. The snap rings 21 located on both sides of the knuckle structure are respectively connected to a corresponding one of the pair of snap connection structures 11.

[0034] Combined with Figure 2-3 As shown, the snap ring 21 is provided in the area where the glove 20 fits with the arc-shaped groove 101.

[0035] In this way, the position of the snap ring 21 is close to the upper part of the arc-shaped connecting plate 10 and relatively close to the position of the perforation, making it easy to pass through the perforation and not easily causing deformation of the glove.

[0036] Furthermore, the perforation is closer to the open end of the arc-shaped groove 101 than the snap connection structure 11. In this way, when the snap ring 21 passes through the perforation and then extends upward to be connected to the snap connection structure 11, it is beneficial for user operation and makes the structure of the arc-shaped connecting plate 10 compact.

[0037] In an alternative embodiment, the snap ring 21 is a closed ring structure and the snap ring 21 is a flexible ring. Optionally, the snap ring 21 is made of a polymer material, for example, the same material as the glove.

[0038] Furthermore, the snap connection structure 11 includes a limiting groove 112, and the limiting groove 112 is configured to have a closed state and an open state. The snap ring 21 is placed in the limiting groove 112 when the limiting groove 112 is in the open state, and forms a limit on the snap ring 21 when the limiting groove 112 is in the closed state.

[0039] In an alternative embodiment, as Figure 4 shown, the snap connection structure 11 includes a hook-shaped portion 111 and a snap block 114. The first end of the hook-shaped portion is connected to the outer wall of the arc-shaped connecting plate 10, the second end extends outward and forms a hook-shaped structure, a card slot 113 is provided at the end of the hook-shaped portion 111, and the snap block 114 is detachably connected to the card slot 113. When the snap block 114 is connected to the card slot 113, the limiting groove 112 is configured in a closed state.

[0040] It can be understood that when the clamping block 114 is disengaged from the hook-shaped portion 111, an open end of the hook-shaped portion 111 forms a limiting groove 112. The snap ring 21 can be placed in the limiting groove 112, and then the clamping block 114 is clamped in the clamping groove 113. At this time, the limiting groove 112 is closed, and the snap ring 21 cannot be disengaged from the limiting groove 112, thereby realizing the limitation of the snap ring 21.

[0041] In an alternative embodiment, the clamping block 114 is connected to the hook-shaped portion 111 through a pin structure 115. The pin structure 115 can be a square or a pin structure with a special-shaped cross-section, which can prevent the relative rotation between the clamping block 114 and the hook-shaped portion 111.

[0042] Further, the one at the distal end in the phalanx structure is defined as the distal phalanx. Hooks 12 are provided on the arc-shaped connecting plate 10 corresponding to the distal phalanx, and an annular connecting member 22 is provided on the distal phalanx. The annular connecting member 22 can be connected to the hook 12.

[0043] In this way, by providing the annular connecting member 22 at the distal phalanx, the connection ability at the fingertip can be increased.

[0044] Combining the above embodiments, the arc-shaped connecting plate connected to the hand exoskeleton is provided in the present utility model, and a snap ring is provided at the phalanx of the glove. The snap ring can be connected to the clamping structure on the arc-shaped connecting plate, so that the glove and the hand exoskeleton can be switched between the coupled and uncoupled states. Especially when it is necessary to replace the glove or the phalanx member of the hand exoskeleton, the glove and the hand exoskeleton can be easily disassembled and assembled.

[0045] Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Those with ordinary knowledge in the technical field to which the present utility model belongs can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to that defined by the claims.
