Problems solved by technology

However, the disadvantage of these structures is that when the wearer enters the swing stage, they cannot provide active swing power-assisted effects, but can only use the swing of the thigh to drive the knee joint movement through training, which is adaptable to the patient's walking and different terrains. come a big impact

Embodiment Construction

[0017] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] see figure 1 , an active knee joint structure with load-bearing self-locking function, the overall structure is firmly connected with the human body through the connecting rods of the thigh and calf and the connecting rod bandages 1, 7, the knee joint connection mechanism and the limit mechanism 3 are connected with the thigh The rods 2 are fixedly connected together. The shank connecting mechanism is connected with the knee joint connecting mechanism through the spline 9, and the two can rotate relatively, and a stressed bearing is housed on the rotating shaft.

[0019] The knee joint connection mechanism is divided into two sides, the inner side and the outer side. The inner side is the side close to the wearer. The main function of the inner side is to complete the limit of the mechanical structur...

Abstract

The invention discloses an active knee joint structure with a function of load-bearing and self-locking. The active knee joint structure with the function of the load-bearing and the self-locking comprises a connecting rod bandage fixed with a thigh and a crus, a knee joint connecting mechanism, a limit mechanism, a crus connecting mechanism, a motor, a harmonic reducer, a self-locking elastic sheet, an oil pressure buffer and a self-recovery torsional spring. The active knee joint structure with the function of the load-bearing and the self-locking can not only guarantee the balance of a wearer in a standing stage through a locking mechanism, but also have the function of assisting power on the wearer in a swinging stage, improves the service efficiency of energy, and strengthens adaptability of the wearer to different landforms.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to an active knee joint structure with a load-bearing self-locking function. Background technique [0002] Among the existing prosthetic and orthotic technologies, many knee-ankle prosthetics and orthotics have a load-bearing self-locking function, which can ensure that the patient maintains a certain stability when entering the standing stage. Knee-ankle prosthetics are mainly adjusted by adjusting the damping coefficient of the pneumatic cylinder, while in orthotics, mechanical locks are used for light and easy-to-wear effects. However, the disadvantage of these structures is that when the wearer enters the swing stage, they cannot provide active swing power-assisted effects, but can only use the swing of the thigh to drive the knee joint movement through training, which is adaptable to the patient's walking and different terrains. come a big impact. [0003] In the existin...
