Embodiments of the present application provide a bending machine and a control method, device, medium and equipment thereof. The bending machine comprises a first motor, a second motor, a vertical shaft, an up-down moving shaft, a swing shaft, a bending piece and a sliding block. The vertical shaft is a shaft structure vertically installed and fixed in position. The up-down moving shaft is axially connected with the vertical shaft and is used to move up and down along the vertical shaft under the control of the first motor. The swing shaft is movably connected with the up-down moving shaft. The sliding block is used to slide up and down under the drive of the second motor and keeps contact with the back inclined surface of the bending piece during the sliding process. The bending piece is movably connected with the swing shaft and has a cutting edge. The bending piece is used to passively move under the action of the sliding block and the swing shaft so that the cutting edge bends the fixed plate. The flexibility of the embodiments of the present application is relatively high and the production efficiency is not affected.

A micro constant passive motion machine for applying short arc constant passive motion to a knee joint of a user includes a base member and a sliding member secured to the base member so as to permit sliding, translational movement of the sliding member relative to the base member. The machine further includes a leg receiving member secured to the sliding member, and one or more motors. The machine further includes a primary rotative component whose rotation is configured to effect, via a connection strut secured to the primary rotative component and the base member, short arc sliding, translational movement of the sliding member relative to the base member. The machine still further includes a second rotative component whose rotation is configured to effect, via a pivot member, continually alternating rotation of the leg receiving member.

This utility model belongs to the field of motion platform technology, specifically an anti-hinged mechanism for a motion platform. It includes a support frame, with a cable hinge body on the left side of the support frame. The cable hinge body is composed of multiple cable placement mechanisms hinged together by hinge shafts. Each cable placement mechanism includes a base plate, a left support plate integrally mounted on the left side of the base plate, and a right support plate integrally mounted on the right side of the base plate. A cover plate is rotatably mounted on the left support plate. The cable hinge body is formed by the interconnection of several cable placement mechanisms. The cable placement mechanism includes a base plate, a left support plate, a right support plate, and a cover plate. These four components form a cable placement cavity, where the cable is placed. The cover plate is rotatably connected to the left support plate, facilitating the placement of the cable into the cable placement cavity. This design effectively prevents damage to the cable during passive movement.

The invention provides a man-machine compatible elbow joint rehabilitation robot, and relates to the technical field of medical instruments. The human-machine compatible elbow joint rehabilitation robot comprises an elbow joint flexion / extension active movement unit, an elbow joint inward rotation / outward rotation active movement unit, an elbow joint passive movement unit and a hand passive movement unit. Some passive motion pairs are additionally arranged at the man-machine connecting position, and the man-machine compatibility requirement can be met without strict alignment of machine joints and human body joints through motion of the passive free pairs. The series elastic driver is added between the driving motor and the load, the elastic characteristic of the tendon is simulated through the series elastic driver to improve the energy efficiency, in addition, part of energy is stored and then released slowly when the motor is started and stopped and is accidentally impacted, the time of the whole process that force generated by the motor acts on a patient is prolonged, and the energy efficiency is improved. The effect of reducing impact on the body of the patient is achieved, secondary injury to the patient when the machine is started and stopped is effectively avoided, and discomfort of the patient is reduced.

The invention relates to the technical field of wearable exercise assistance and rehabilitation assistive devices, in particular to a passive exercise assistance system and a method for providing passive assistance for the human body of the passive exercise assistance system, and the system mainly comprises a flexible assistance protection tool worn on the body of a user next to the skin and provided with a plurality of anchor point interfaces; the adjustable anchor point is arranged at the anchor point connector so as to adjust the mounting position and angle of the elastic band assembly mounted at the anchor point connector according to the body type and action requirements of different users; the elastic belt assembly is connected with the anchor point connector, when the elastic belt assembly is bridged between the two parts of the human body, the elastic belt assembly is stretched to store mechanical energy in the first stage of movement of the human body, and rebounds to release the mechanical energy in the opposite movement stage so as to apply assisting force to the human body along a preset force line; a bridging path and tension setting may be determined based on a preset motion digital twinning and depth motion data analysis system. Therefore, the problems that an existing passive power assisting device is insufficient in comfort, poor in universality, lack of individualized power assisting and the like are solved.

A system includes a platform supporting a vehicle on a first side of the platform and a passive motion device arranged on a second side of the platform opposite the first side to move upon actuation. A mechanical actuator actuates the passive motion device based on motion of one or more wheels of the vehicle to change a position of the vehicle. The position of the vehicle relative to the platform is unchanged and the passive motion device is actuated solely by motion of the one or more wheels of the vehicle to change the position of the vehicle.
