Problems solved by technology

[0004] Existing literature also records that the upper limb exoskeleton uses two elastic ropes on the back. The two elastic ropes can provide pulling force for the human body when the user lifts heavy objects and play a role in assisting. However, the pulling force will be lost during the assisting process. Increase the stress on the user's spine and lower back, and increase the extra burden, which will cause damage to the lower back

Embodiment Construction

[0034] Specific examples of the present invention are given below. The specific embodiments are only used to further describe the present invention in detail, and do not limit the protection scope of the claims of the present application.

[0035] The present invention provides an upper extremity lumbar back assist exoskeleton (exoskeleton for short, refer to Figure 1-12 ), characterized in that the exoskeleton includes a waist strap 1, No. 1 power part 5, No. 2 power part 11 and vest;

[0036] The lower part of the front side of the vest is hinged with the upper ends of the two No. 1 power parts 5, the lower ends of the two No. 1 power parts 5 are hinged with the front side of the waist strap 1, and the two No. 1 power parts 5 are symmetrically distributed on the left and right; The upper end of the No. 2 power part 11 is hinged with the middle part of the vest rear side, and the lower end of the No. 2 power part 11 is hinged with the middle part of the waist strap 1 rear s...

Abstract

The invention discloses an upper limb waist and back power-assisted exoskeleton which comprises a waist binding strap, first power piece, a second power piece and a waistcoat. The lower portion of the front side of the waistcoat is hinged to the upper ends of the two first power pieces, the lower ends of the two first power pieces are hinged to the front side of the waist binding strap, and the two first power pieces are distributed in a bilateral symmetry manner. The upper end of the second power piece is hinged to the middle of the rear side of the waistcoat, and the lower end of the second power piece is hinged to the middle of the rear side of the waist binding strap. In the process that the exoskeleton is worn to carry a heavy object from a low position to a high position, the exoskeleton applies upward pulling force to the heavy object through hydraulic muscles on the rear side, meanwhile, the two first power pieces on the front side extend to provide constant supporting force, then force borne by the spine of a human body is reduced, and damage to the spine is avoided.

Description

technical field [0001] The invention belongs to the technical field of exoskeleton booster devices, in particular to an upper limb lumbar back booster exoskeleton. [0002] technical background [0003] When manual laborers are engaged in activities such as carrying and carrying, high loads and long hours of labor can lead to damage to the back and back, and even lead to illnesses and other phenomena, reducing their work efficiency. The external force auxiliary device can provide a certain amount of assistance for the user, reduce the user's own effort, prevent or reduce the damage to the back and back caused by labor, and does not affect the comfort and efficiency of the work. [0004] Existing literature also records that the upper limb exoskeleton uses two elastic ropes on the back. The two elastic ropes can provide pulling force for the human body when the user lifts heavy objects and play a role in assisting. However, the pulling force will be lost during the assisting p...
