Problems solved by technology
The problem of direct drive is that there are many restrictions on space layout, insufficient motor torsional torque, and poor self-locking performance
The link drive can have more space options, and can provide a larger torque at a specific angle, and it is easy to realize the self-locking of the mechanism itself, but the problem of many link drive devices is that they are large in size and heavy in weight

Embodiment Construction
[0020] The present invention will be described in detail below with reference to the drawings and embodiments.
[0021] Such as figure 1 As shown, the present invention provides a wearable dynamic joint rehabilitation device, which includes an upper support plate 1 and a lower support plate 2. A push rod drive mechanism 3 is provided on the upper support plate 1. The output end of the push rod drive mechanism 3 is a push rod 3-1 that outputs linear motion, and the end of the push rod 3-1 is connected to a triangular connecting rod 5 through a hinge shaft 4 The second end of the triangular connecting rod 5 is hinged to the upper support plate 1, the third end of the triangular connecting rod 5 is hinged to one end of the connecting rod 6, and the other end of the connecting rod 6 is hinged to the lower support plate 2.
[0022] In the above embodiment, such as Figure 4 As shown, the push rod driving mechanism 3 includes a support 3-2, a motor 3-3, a ball screw pair 3-4, and a push...

Description
Technical field [0001] The invention relates to a joint rehabilitation device, in particular to a wearable dynamic joint rehabilitation device. Background technique [0002] Assisted rehabilitation devices for the knee joint can generally be divided into wearable and non-wearable, power-driven and non-power-driven. The wearable auxiliary rehabilitation device refers to an appliance worn outside the large and small legs of the human body, which limits the extension and flexion of the joint within a suitable angle range, or maintains the knee joint at a certain angle to promote the early rehabilitation of the knee joint function. The current wearable non-power assisted rehabilitation device has a relatively simple structure, 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 wearable. It can increase the pat...
