AI Technical Summary
The existing shoulder wear fixing scheme for hand exoskeletons relies on adhesive methods such as Velcro, which leads to reduced bond strength and failure problems. At the same time, the shoulder straps lack elasticity, affecting the movement flexibility of the exoskeleton.
A shoulder wear device is designed, including main side shoulder pads, ipsilateral and different sides annular straps, upper and lower shoulder pads and elastic straps, and adopts a press-type tension fixing and elastic pads to ensure the reliable fixing and movable space of the control box.
Through the design of the embossed strap tensioning and elastic cushion, the fixing reliability of the control box is improved, the bonding failure is avoided, and the flexibility of exoskeleton is increased.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rehabilitation auxiliary products, in particular to a shoulder wearing device of a hand exoskeleton. Background Art
[0002] Manipulators are rehabilitation-assist products used to assist patients with their daily lives and conduct rehabilitation training. They are worn and used frequently in daily life, and require high wearability and portability. Hand exoskeletons are a type of rehabilitation manipulators, consisting of an exoskeleton bound to the patient's hand and a control box that drives the exoskeleton. The control box includes a drive part, a battery, and a motor. For patients in the rehabilitation period, their hand strength is relatively weak, so the weight of the exoskeleton should be as light as possible. For this reason, this type of exoskeleton will place the heavier control box on the shoulder to reduce the weight on the patient's hand and arm, making it easier for the wearer to use the device.
[0003] At present, the wear and fixation scheme of this type of rehabilitation hand exoskeleton is still rigidly fixed to the shoulder strap by means of Velcro or other methods. Velcro and other adhesive methods will cause the bonding strength to decrease or even fail after multiple bonding; and the shoulder strap is not elastic, and if it is tied too tightly, the patient will feel resistance from the control box and the strap when using the exoskeleton, affecting the flexibility of the exoskeleton movement. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a shoulder-worn device for a hand exoskeleton, which is convenient for reliably arranging the control box of the hand exoskeleton on the patient's shoulder while leaving a certain amount of room for movement, thereby increasing the flexibility of using the exoskeleton.
[0005] The technical solution adopted by the utility model to solve its technical problems is: to provide a shoulder wearing device for a hand exoskeleton, including a main side shoulder pad arranged on a shoulder close to one side of the hand exoskeleton, the two sides of the main side shoulder pad are respectively provided with a same-side strap and an opposite-side strap, the main side shoulder pad includes a lower shoulder pad and an upper shoulder pad movably connected to the lower shoulder pad, the upper shoulder pad is provided with an exoskeleton control box connecting structure, the same-side strap and the opposite-side strap are both annular and are provided with length adjustment structures.
[0006] The exoskeleton control box connection structure is a Velcro fleece surface, and the Velcro fleece surface matches the Velcro hook surface arranged on the bottom surface of the control box.
[0007] Two elastic bands are fixed to the lower surface of the upper shoulder pad, and the upper surface of the lower shoulder pad is connected to the upper surface of the lower shoulder pad through the elastic bands.
[0008] The length adjustment structure includes a mouth buckle and a press buckle arranged on the same-side strap and the opposite-side strap.
[0009] The same-side strap, the opposite-side strap and the lower shoulder pad are made of PVC.
[0010] Beneficial Effects
[0011] The shoulder wearing device of the hand exoskeleton provided by the utility model makes the control box strap more reliable and less prone to failure through a buckle-type strap tensioning and fixing scheme and a cushion layer with elastic expansion and contraction capabilities. At the same time, the control box has a certain activity space, which increases the flexibility of the exoskeleton during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
[0018] like Figure 1 , 2As shown in Figure 3, the utility model provides a shoulder-worn device for a hand exoskeleton, including a main-side shoulder pad arranged on a shoulder near one side of the hand exoskeleton, with same-side straps 1 and opposite-side straps 8 provided on both sides of the main-side shoulder pad, the main-side shoulder pad including a lower-layer shoulder pad 3 and an upper-layer shoulder pad 4 movably connected to the lower-layer shoulder pad 3, an exoskeleton control box connection structure provided on the upper-layer shoulder pad 4, and both the same-side straps 1 and opposite-side straps 8 are annular and provided with length adjustment structures. Among them, the same-side strap 1 refers to a strap on the same arm side as the hand exoskeleton to be loaded, which is passed through the armpit of the shoulder where the main-side shoulder pad is located to achieve binding, and the opposite-side strap 8 refers to a strap arranged on the other side of the main-side shoulder pad, which is longer than the same-side strap 1, and can be passed through the armpit of the other side to complete fixation after the strap length is extended to the longest.
[0019] In a specific embodiment, the connection structure of the exoskeleton control box is a Velcro surface, and the Velcro surface matches the Velcro hook surface provided on the bottom surface of the control box. In other embodiments, other methods such as snaps and adhesives can also be used to achieve detachable connection. Two elastic bands 2 are fixed to the lower surface of the upper shoulder pad 4, and the two elastic bands 2 are arranged in parallel. The two ends of the elastic bands 2 are fixed to the upper surface of the lower shoulder pad 3 to achieve relative movement between the upper shoulder pad 4 and the lower shoulder pad 3, which can ensure that the control box bonded to the upper shoulder pad 4 can move relative to the shoulder within a certain range, and prevent the control box from being tied too tightly and affecting the flexibility of the hand exoskeleton movement.
[0020] In a specific embodiment, the length adjustment structure includes a shaped buckle and a pressure buckle arranged on the same-side strap 1 and the opposite-side strap 8, specifically, the same-side shaped buckle 5, the opposite-side shaped buckle 6, the same-side pressure buckle 7 and the opposite-side pressure buckle 9. The shaped buckle and the pressure buckle are both prior art, wherein the pressure buckle uses a spring to relax and tighten, which is more reliable and less likely to fail after repeated use. When in use, the length of the strap can be adjusted by adjusting the position of the strap on the shaped buckle. When the length is adjusted to a suitable length for tightening, the pressure buckle is pressed to fix the length of the strap to prevent slipping.
[0021] In a specific embodiment, the same-side strap 1, the opposite-side strap 8 and the lower shoulder pad 3 may all directly contact the skin, so their materials are PVC fabrics that have passed biocompatibility testing to ensure that the utility model can be used as an accessory of the hand exoskeleton on medical devices.
