Portable and wearable upper limb exoskeleton rehabilitation training device

Abstract

The invention discloses a portable and wearable upper limb exoskeleton rehabilitation training device. The portable and wearable upper limb exoskeleton rehabilitation training device is characterized by comprising a back module, two shoulder modules, two elbow modules and a bearing mechanism, wherein the back module is used for bearing a control system and a battery power component and used for achieving the bearing function; the two shoulder modules are arranged on the left side and the right side of the back module; the two elbow modules are connected with the two shoulder modules; the bearing mechanism is arranged on the back module and used for achieving the bearing function. By means of the portable and wearable upper limb exoskeleton rehabilitation training device, the structure can be effectively simplified, the weight can be reduced, the size can be reduced, the battery life can be prolonged, portability of the device is enhanced, and the effect of assisting a patient with a damaged upper limb movement function in accepting rehabilitation training is guaranteed; meanwhile, due to the modular design, the patient can choose to wear the device with the shoulders or the whole arm module for certain life assisting, and the device has wider practicality.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a portable wearable upper limb exoskeleton rehabilitation training device. Background technique [0002] After the onset of stroke, patients often have movement disorders, sensory disorders, speech disorders, cognitive impairments, etc. Among these sequelae, movement disorders are the most common. Relevant studies have shown that about 85% of stroke patients have symptoms of upper limb paralysis in varying degrees, and in the post-stroke rehabilitation process, the functional recovery of upper limbs lags behind that of other parts. According to relevant statistical results, 6 months after the onset of stroke, 30%-60% of hemiplegic patients still cannot recover their upper limb function, and 25% of patients still have severe upper limb paralysis 5 years after stroke. This makes the patient's recovery period extremely long. [0003] Exoskeleton rehabilitation training robot is a n...

AI Technical Summary

Problems solved by technology

[0004] 1. The mechanism is complex and bloated, and it is inconvenient to wear. The desktop mechanism is used to integrate the power supply and drive equipment inside the platform, which makes the mechanical mechanism large and inflexible. It has high requirements for the use of space and is not easy to carry and popularize.

The joints of its arm mechanism adopt the design of motor superimposed reducer, which is very bulky, which makes it inconvenient for users to wear and feels heavy

[0005] 2 The traditional upper limbs are made of all-metal materials, and the reducer is made of multi-stage steel reducer, which has the defects of heavy weight and high noise. In addition, the protruding motor and reducer are easy to interfere with the external environment, causing unpredictable risk

[0006] 3. Because the traditional upper limb rehabilitation robots are designed in one-piece structure, they are relatively rigid and cannot be carried by users to meet their different training needs, and cannot assist patients in their daily life

[0007] 4. The complex and heavy mechanism and the extensive use of multi-stage reducers lead to the high economic cost and high price of the current upper limb rehabilitation training robot, which is not conducive to its production and promotion, and cannot meet the needs of a large number of patients in our country
