Embodiment 1

[0049] see Figure 1-7 , the first embodiment of the present invention provides a knee joint auxiliary exercise device, which is applied to a knee joint support, and the knee joint support includes a first fixing member worn on the thigh, and a second fixed member worn on the calf. The fixing piece, the knee joint auxiliary exercise device includes a box body 201, a power source 301 arranged on the box body 201, a first rotating assembly, a telescopic assembly, and a second rotating assembly disposed on the telescopic assembly;

[0050] The box body 201 is rotatably connected to the first fixing member through the first rotating assembly, and the telescopic assembly is rotatably connected to the second fixing member through the second rotating assembly, that is, the box body 201 is rotatably connected to the first fixing member through the first rotating assembly. The power source 301 is arranged on the box body 201, and the telescopic assembly is rotatably connected to the se...

Embodiment 2

[0071] see Figure 8 , the second embodiment of the present invention provides a first control method of an auxiliary rehabilitation device, and the control method is applied to the auxiliary rehabilitation device of the above-mentioned first embodiment.

[0072] The control method includes steps S101 to S104:

[0073] S101, connecting the two ends of the auxiliary rehabilitation device to the first fixing member and the second fixing member respectively;

[0074] That is, the first connecting arm 601 is detachably connected to the thigh connecting plate 102 through the first locking structure, and the second connecting arm 602 is detachably connected to the calf connecting plate 104 through the second locking structure.

[0075] S102, toggle the mode switch 203 to adjust the current operating mode of the power source 301.

[0076] S103, if the current operating mode is adjusted to the active motion mode, control the power source to rotate back and forth at a first preset rota...

Embodiment 3

[0082] see Figure 9 , the second embodiment of the present invention also provides a second control method for an auxiliary rehabilitation device, and the control method is applied to the auxiliary rehabilitation device in the first embodiment.

[0083] The control method includes steps S201 to S206:

[0084] S201, connecting the two ends of the auxiliary rehabilitation device on the first fixing member and the second fixing member respectively;

[0085] That is, the first connecting arm 601 is detachably connected to the thigh connecting plate 102 through the first locking structure, and the second connecting arm 602 is detachably connected to the calf connecting plate 104 through the second locking structure.

[0086] S202, toggle the mode switch 203 to adjust the current operating mode of the power source 301.

[0087] S203, when the operation mode is adjusted to the auxiliary movement mode, the patient performs rehabilitation walking, so that the telescopic rod 401 slid...

Abstract

The invention discloses a knee joint auxiliary movement device and a control method thereof.The knee joint auxiliary movement device comprises a box body, a power source arranged on the box body, a first rotating assembly and a telescopic assembly, and a second rotating assembly arranged on the telescopic assembly enables the box body to be rotationally connected with a first fixing piece through the first rotating assembly; the telescopic assembly is rotationally connected with the second fixing piece through the second rotating assembly, the power source drives the telescopic assembly to stretch out and draw back, when the telescopic assembly stretches out and draws back, the power source rotates relative to the first fixing piece, the telescopic assembly rotates relative to the second fixing piece, and therefore the first fixing piece rotates relative to the second fixing piece; therefore, assistance is provided for knee joint bending / resetting. The technical problems that in the prior art, an auxiliary rehabilitation device is single in function, cannot provide assistance for a patient during walking, and lacks the function of assisting active movement are solved.

Description

technical field [0001] The invention relates to the technical field of joint movement assistance, in particular to a knee joint auxiliary movement device and a control method thereof. Background technique [0002] Rehabilitation after knee surgery is a common problem faced by orthopedics. Due to lack of exercise or poor exercise effect after surgery, some patients have not recovered their knee joint function to meet the normal needs of daily life until the injury is healed. [0003] The emergence of the CPM machine enables patients to obtain passive exercise rehabilitation effects. The CPM machine can be connected and fixed on the seat or nursing bed frame. It is a kind of physical exercise therapy. It usually uses power transformer, stepper motor, control board, driver, limit start switch, and casing as the main power components. Linear slide or reducer is used as the main power component. It simulates the human body to perform movements such as reciprocating stretching an...
