Self adaptive support weight losing device for lower limb exoskeleton rehabilitation robot

Abstract

The invention discloses a self adaptive support weight losing device for a lower limb exoskeleton rehabilitation robot. The self adaptive support weight losing device comprises a gravity center following device arranged on the upper face of a lift platform moving plate and a lifting device arranged on the lower face of the lift platform moving plate and is characterized in that the gravity center following device comprises a slot type cam, a cam swing rod, a power exoskeleton support plate connected with a power exoskeleton device, one end of the cam swing rod is matched with an annular sliding slot of the slot type cam in a contacted mode through an idler wheel, the other end of the cam swing rod is connected with a parallelogram connecting rod structure, the rear edge of the parallelogram connecting rod structure is hinged to a stand column of the lift platform moving plate, and the front edge of the parallelogram connecting rod structure is hinged to a vertically moving mechanism which forms a sliding pair with the power exoskeleton support plate.

Description

technical field [0001] The invention relates to a rehabilitation medical device, in particular to a lower limb exoskeleton rehabilitation robot. Background technique [0002] Patients with cerebrovascular diseases such as stroke and central nervous system injuries such as brain or spinal injuries have a high disability rate, and the main sequelae include acute neurological paralysis, etc., and they have different degrees of loss of living ability and working ability. According to statistics, there are currently 8.77 million patients with limb dysfunction in my country due to stroke, spinal injury and various accidents, and more than half of them can improve their limb function through training, including regaining the ability to walk. Traditional rehabilitation training begins with the hands-on guidance of a professional physical therapist, and then the patient's healthy upper limbs or their family members or nurses manually pull the patient's affected limbs repeatedly.

Problems solved by technology

Among them, the first type is a suspension device, which is bulky and restricts the upper limbs of the patient, making it impossible for the patient to move independently, and the patient is prone to discomfort after long-term training.

The latter two are lumbar support and weight-reducing devices, but neither can be used with lower limb exoskeleton or other orthotics. Therefore, they are only suitable for rehabilitation training for patients with a certain degree of lower limb muscle strength in the late rehabilitation period. The scope of application is narrow, and in order to obtain Stable weight loss, difficult to control
