[0037] When the flexible traction upper arm exoskeleton provided by the present invention is in use, the user first wears the exoskeleton on the body through the shoulder strap slot 3, and then holds the handle 1 to fix it to the object to be transported. The gravity of the object is transmitted to the two traction belts 2 through the two handles 1, and further transmitted to the two flexible elastic belts 5 through the two traction belts 2. The two flexible elastic belts 5 are stretched and provide reaction force to resist the tendency of being stretched, thereby providing assistance for transporting the object; at the same time, the two traction belts 2 overlapping with the two flexible elastic belts 5 are also automatically stretched. When the two traction belts 2 are straightened, the two traction belts 2 and the two flexible elastic belts 5 jointly bear the gravity of the object.

[0038] In the above embodiment, preferably, please continue to refer to Figure 2 The lower ends of the two flexible elastic bands 5 are respectively fixed to the second ends of the two traction belts 3, and the upper ends of the two flexible elastic bands 5 are installed with first adjustment buckles 6. At the same time, a plurality of positioning grooves 7 are arranged at intervals on the two traction belts 2 within the range of the fixing plate 4. The upper ends of the flexible elastic bands 5 are connected to the traction belts 2 through the first adjustment buckles 6 and the positioning grooves 7, and the excess traction belts 2 are folded and stored in the lower part of the flexible elastic bands 5. Through the above arrangement, the first adjustment buckle 6 can be connected to the positioning grooves 7 at appropriate positions according to different user needs, thereby providing different degrees of assistance.

[0039] In the above embodiments, preferably, please refer to Figure 1 and Figure 2 The flexible traction upper arm exoskeleton further includes a telescopic box 8 disposed outside the fixing plate 4, and the shape of the telescopic box 8 is adapted to the shape of the fixing plate 4, so as to encapsulate the flexible traction mechanism in the telescopic box 8, and the two lower ends of the telescopic box 8 are provided with stoppers 9 for preventing the stored traction belt 2 from escaping. Through the above arrangement, the flexible traction mechanism can be hidden inside the telescopic box 8 to protect the flexible traction mechanism, and the excess length of the traction belt 2 can be stored in the telescopic box 8.

[0040] In the above embodiment, preferably, the handle 1 can be replaced according to the shape of different objects. For example, when carrying objects with smooth surfaces, the handle 1 can be replaced with a suction cup mechanism. Figure 4 and Figure 5The suction cup mechanism 9 includes: a suction cup 91, which can be adsorbed on an object with a smooth surface by negative pressure; a pressure relief valve 92, which is arranged on the surface of the suction cup 91 and is used to release pressure to separate the suction cup 91 from the object; a cushion block 93, a transition plate 94 and a handle 95, which are arranged on the back side of the suction cup 91 in sequence and are fastened to the suction cup 91 by fastening screws 96, and a traction belt groove 97 is provided on the transition plate 94, and the traction belt 2 passes through the traction belt groove 97 to hang the suction cup mechanism 9 on the first end of the traction belt 2. Through the above-mentioned arrangement, negative pressure can be generated by squeezing the air in the suction cup 91, so that the suction cup 91 is tightly adsorbed on the object with a smooth surface, and then the object can be transported and moved; when the object is transported to the designated position, the pressure relief valve 92 can be opened to separate the suction cup 91 from the object.

[0041] In the above embodiments, preferably, please refer to Figure 3 The outer side of the handle 1 is fixedly connected with a handle pad 10. Through the above arrangement, the contact between the palm skin and the handle 1 can be isolated by the handle pad 10 to prevent the palm from being cut or bruised by the handle.

[0042] In the above embodiment, preferably, a finger wearing buckle 11 is fixed on the outside of the handle pad 10. Through the above arrangement, when the user is carrying heavy objects, the fingers of both hands can be inserted into the finger wearing buckle 11 to fix the finger position and prevent the palm from sliding sideways.

[0043] In the above embodiment, preferably, an anti-gravity shoulder strap 12 is installed at the lower part of the shoulder strap slot 3, and the anti-gravity shoulder strap 12 is composed of a 3D airbag array, and the airbags are connected by small channels. Through the above arrangement, the anti-gravity shoulder straps 12 on both sides can contact the user's shoulders to set off the downward pressure of the shoulders to reduce the uneven force damage. When the airbags are in a stressed state, the airflow flows mutually to produce uniform force, sharing the pressure in terms of area, and there are gaps between the airbags to have a ventilation effect.

[0044] In the above embodiment, preferably, a second adjusting buckle 13 suitable for adjusting the length of the traction belt 2 is provided on the traction belt 2 near the wrench 1. Through the above arrangement, the second adjusting buckle 13 can be fixed at different adjustment positions according to the length required by the user, thereby adjusting the traction belt 2 to a suitable length.

The first limiting shaft assembly 14 is composed of a shaft seat and two limiting shafts. The shaft seat is fastened to the fixing plate 4. The two limiting shafts are installed on the shaft seat, and a gap is left between the two limiting shafts for the traction belt 2 to pass through; please refer to Figure 3At the same time, a second limiting shaft assembly 15 is arranged at the second end of the shoulder belt slot 3. The second limiting shaft assembly 15 is composed of a shaft seat and a limiting shaft. The shaft seat is fastened to the first end of the shoulder belt slot 3. The limiting shaft is installed on the shaft seat, and a gap is left between the limiting shaft and the shoulder belt slot 3 for the traction belt 2 to pass through. The second end of the traction belt 2 passes through the second limiting shaft assembly 15 and the first limiting shaft assembly 14 in sequence and then enters the telescopic box 8. Through the above-mentioned settings, the traction belt 2 can be guided to pass through the path through the above-mentioned limiting shaft assemblies, which plays the role of guiding the traction belt 2 and limiting the swing of the traction belt 2.
