Waist assisting robot

Abstract

The invention relates to a waist assisting robot. The waist assisting robot comprises a back skeleton, an outer shell accessory, a drive device and exoskeleton lower limb parts. The back skeleton andthe outer shell accessory are fixed to the human trunk through body binding, and flexible binding belts are mounted on the upper portion of a backrest frame. The outer shell accessory comprises a front shell, a rear shell and other parts. The drive device comprises a left drive device and a right drive device. The left drive device and the right drive device are fixed to the back skeleton correspondingly, the drive device is located on the two sides of the hip joint of the human body, and the lower limb parts are fixedly mounted on the left side and the right side of the drive device. The waist assisting robot has the beneficial effects that the structure is simple, the body weight is low, control is convenient, motion is flexible, the comfort is high, the waist assisting robot is easy towear, the robot provides mounting positions of the flexible binding belts of the trunk and the thighs, a user flexibly makes contact with the robot through binding devices, wear is easy, attachment istight, robot joints are coupled with human body joints, and good comfort is provided for the user.

Description

technical field [0001] The invention relates to the technical field of assisting robot research, in particular to a waist assisting robot. Background technique [0002] According to statistics, as of 2017, the number of patients with lumbar diseases in my country has exceeded 300 million, making it the second most outpatient disease, second only to colds. Overwork, sudden external force, bad posture, cold and damp are the main causes of low back pain. Bending and carrying is a common action in daily activities of the human body, which generates the greatest pressure on the lumbar spine. For manual workers engaged in the transportation industry, lower back pain and upper limb pain are more obvious than fatigue in various parts of the body. Therefore, there is a need for a low-cost, simple method to solve this type of problem. [0003] At present, some mechanical exoskeletons at home and abroad mainly drive the human body to perform stable passive movements, with complicated...

Problems solved by technology

[0003] At present, some mechanical exoskeletons at home and abroad mainly drive the human body to perform stable passive movements, with complicated structures and poor flexibility; some robots have drives for each motion pair, which not only increases a lot of control costs, but also has poor control effects and is extremely It is easy to bring sports hazards; some robots are designed with ankle joints enough to unload the force on the ground, but it is extremely difficult to wear, and the experience is not good, and the cost is high; some robots use unpowered forms, but The power-assisted effect is lacking, and the knee joint cannot be self-locked; some robots use simple binding or even metal contact to contact the human body, which makes the power-assisted unstable and dangerous
