Abstract

The invention discloses a self-service dining machine. A column is installed on the chassis. A large arm is hinged on the upper end of the column. There is a telescopic small arm in the large arm. The top of the small arm is connected to the tableware through the wrist joint. There is a right foot pedal on the chassis. Plate and left foot pedal, the knee control mechanism is connected to the column, the user can adjust the upper arm, forearm, wrist joint and tableware by operating the right foot pedal, left foot pedal and knee control mechanism with both feet and knees gesture to help the user eat. The invention is supported by upright columns, and does not require the user to bear the weight of the apparatus. The invention adopts a purely mechanical device, has good reliability, low price and strong flexibility.

Description

technical field [0001] The present invention relates to a kind of mechanical device for assisting the disabled. Background technique [0002] According to the survey of domestic and foreign disabled products market, the products for upper limb prosthesis mainly include intelligent upper limb prosthesis and myoelectric prosthesis. The intelligent upper limb prosthesis is equipped with a slip sensor on the contact part of the prosthetic hand and the object being held, which can output corresponding signals when there is relative sliding between the object and the contact surface of the hand. Action, a prosthetic hand with physical adaptation, is still being explored. Myoelectric prosthesis, also known as myoelectric-controlled artificial limb, uses the electrical signals generated by the stump muscles of the stump person, and the electrical signals generated by the sensors installed on the prosthetic hand are fed back to the brain and the movements of the prosthetic hand can ...
