Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Such as Figure 1~5 As shown, the present invention includes an upper support plate 1 and a lower support plate 2, and a push rod drive mechanism 3 is arranged on the upper support plate 1, and the output end of the push rod drive mechanism 3 is a push rod 3-1 for outputting linear motion, and the push rod drive mechanism 3 The end of the rod 3-1 is tightly connected with the horizontal connecting rod 4, and the two ends of the horizontal connecting rod 4 are respectively connected with the lower support plate 2 through the connecting rod mechanism. The part where the lower support plate 2 is connected with the link mechanism is an elastic piece 5, and the elastic piece 5 is connected with the lower support plate 2 as a whole. Two elastic pieces 5 are symmetrically distributed on both sides of the central axis of the lower support plate 2 . A...

Abstract

The invention relates to a continuously-variable series flexible drive based wearable dynamic knee joint. The wearable dynamic knee joint is characterized by comprising an upper supporting plate and a lower supporting plate; a push rod driving mechanism is arranged on the upper supporting plate, an output end of the push rod driving mechanism is a push rod which outputs linear movement, the end of the push rod is fixedly connected with a transverse connecting rod, and two ends of the transverse connecting rod are connected with the lower supporting plate through link mechanisms respectively. An elastic sheet is arranged at the joint of the lower supporting plate and each link mechanism and integrally connected with the lower supporting plate, and the two elastic sheets are symmetrically distributed on two sides of the center axis of the lower supporting plate. A first gear is fixedly arranged at the lower end of the upper supporting plate, a second gear is fixedly arranged at the upper end of the lower supporting plate, and the second gear is meshed with the first gear.

Description

technical field [0001] The invention relates to a dynamic knee joint, in particular to a wearable dynamic knee joint based on continuously variable serial flexible drive. Background technique [0002] Auxiliary rehabilitation devices for the knee joint can generally be divided into wearable and non-wearable, power-driven and non-power-driven. Wearable auxiliary rehabilitation devices refer to devices worn outside the legs of the human body, which limit the extension and flexion of the joints within a suitable angle range, or maintain the knee joints at a certain angle, so as to promote early recovery of knee joint function. At present, the structure of wearable non-power-assisted rehabilitation devices is relatively simple, and generally supports and stabilizes the patient's damaged knee joint, and is relatively simple to use. Many power-assisted knee rehabilitation devices are non-wearable. This auxiliary rehabilitation device is more powerful than the wearable device. It...
