Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for hemiplegic patients, in particular to a high-performance auxiliary mechanical arm for hemiplegic patients. Background Art

[0002] Hemiplegia, also known as hemiplegia, refers to the movement disorder of the upper and lower limbs, facial muscles and lower tongue muscles on the same side. It is a common symptom of acute cerebrovascular disease. Although patients with mild hemiplegia can still move, they often walk with their upper limbs bent and their lower limbs straight. The paralyzed lower limbs make a half circle with each step. This special walking posture is called hemiplegic gait. Severe cases are often bedridden and lose their ability to live.

[0003] When hemiplegic patients want to sit up after being bedridden, they are usually helped by their family members. This is an extremely physically demanding task and a burden to the family members. Moreover, the family members cannot stay by the patient's side at all times, which makes it very inconvenient for hemiplegic patients to sit up. In this regard, we proposed a high-performance hemiplegic patient auxiliary robotic arm to solve the above problems. Utility Model Content

[0021] A through slot 14 is provided on the top wall of the cross bar 7, and the through slot 14 is communicated with the inner cavity of the cross bar 7. The adjusting mechanism 10 includes a moving block 15, a pair of fixing seats 16 and a second servo motor 18. The moving block 15 is slidably connected in the through slot 14. The pair of fixing seats 16 are respectively arranged at both ends of the through slot 14. The fixing seats 16 are fixedly welded on the top wall of the cross bar 7. A screw 17 is rotatably installed between the pair of fixing seats 16. The moving block 15 is threadedly connected to the screw 17 through the screw hole provided. The bottom end of the moving block 15 is fixedly welded to the end of the slide bar 8 away from the flip plate 9. When the screw 17 rotates, the moving block 15 can be driven to slide in the through slot 14, thereby driving the slide bar 8 to slide in the inner cavity of the cross bar 7, thereby adjusting the flip plate 9 and realizing the retraction and extension of the flip plate 9.

[0022] The second servo motor 18 is fixedly mounted on a fixing base 16 close to the support plate 5 , the output end of the second servo motor 18 is transmission-connected to the screw 17 , the second servo motor 18 and the first servo motor 11 are both electrically connected to an external controller via wires, and the second servo motor 18 is used to drive the screw 17 to rotate.
