Problems solved by technology

[0003]Existing limb rehabilitation training devices have a small range of motion in the rehabilitation training process except for the knee joints, and the surrounding muscle groups cannot achieve the expected rehabilitation training effect; Existing limb rehabilitation training devices do not take into account the training needs of the human ankle joint, or do not have an ankle joint training function, which will also cause the ankle joint to not be well trained during the rehabilitation training process, and the expected rehabilitation training effect cannot be achieved ; And the existing limb rehabilitation training device does not have effective ankle pump movement, and cannot realize the function of preventing venous thrombosis
[0004] In addition, the existing crank-rocker type limb training device has a small pedal inclination angle and insufficient ankle range of motion, which also cannot well meet the needs of rehabilitation training. The pedaling posture lacks an effective adjustment mechanism, which is difficult to meet different rehabilitation training situations

Embodiment 1

[0043] see Figure 1-4As shown, this embodiment introduces a crank-rocker-type limb training device, the crank-rocker-type limb training device includes a base and a crank 4, a rotating shaft 23, a rocker 21, a connecting rod arranged on the base 22. The supporting aid 3 and the first screw adjusting mechanism 6 . The crank 4 is rotatably installed on the base; the rotating shaft 23 is installed on the base and is located on one side of the crank 4, and the rotating shaft 23 can move relative to the base, so that the The rotating shaft 23 can move back and forth relative to the base; one end of the rocker 21 forms a rotating pair with the rotating shaft 23, and the rocker 21 can swing relative to the rotating shaft 23; one end of the connecting rod 22 is connected to the rotating shaft 23. The other end of the rocker 21 forms a rotating pair; the supporting aid 3 is fixedly installed on the connecting rod 22 , and the supporting aid 3 or the other end of the connecting rod 22...

Embodiment 2

[0061] see Figure 5 , this embodiment introduces another crank-rocker type limb training device. The difference between this embodiment and the first embodiment is the installation position of the support aid 3 on the connecting rod 22 through the second lead screw adjustment mechanism 9 .

[0062] Specifically, see Figure 5 , a second screw adjustment mechanism 9 is provided between the support aid 3 and the connecting rod 22 , and the second screw adjustment structure 9 is configured to adjust the support aid 3 on the connecting rod 22 To adjust the attitude inclination angle of the support aid 3 from the installation position on the top, the first lead screw adjustment mechanism 6 can be used as two realization structures for adjusting the attitude angle of the support aid 3 .

[0063] see Figure 5 , in this embodiment, the second screw adjustment mechanism 9 is arranged at the bottom of the support aid 3, and the second screw adjustment mechanism 9 includes a second s...

Embodiment 3

[0068] see Image 6 , this embodiment introduces a third crank-rocker type limb training device. The difference between this embodiment and the first embodiment is that the first screw driving device of the first screw adjusting mechanism 6 in this embodiment is a rotating handle 61 '. Other structures are basically the same, so the description is not repeated.

[0069] Specifically, see Image 6 , the rotating handle 61 ′ is arranged at the rear end of the outer side of the base, and the rotating handle 61 ′ is connected to the rear end of the first lead screw 63 in a driving connection, and the rotating handle 61 ′ can drive the first lead screw 63 . When the lead screw 63 rotates, the first lead screw nut 64 converts the rotation of the first lead screw 63 into the linear movement of the first lead screw nut 64 along the first lead screw 63, thereby driving all the The rotating shaft 23 moves along the length direction parallel to the first lead screw 63 to realize the a...

Abstract

The invention discloses a crank rocker type limb training device which comprises a base. The crank is rotationally mounted on the base; the rotating shaft is mounted on the base, is positioned on one side of the crank, and can move relative to the base; one end of the rocker and the rotating shaft form a rotating pair, and the rocker can swing relative to the rotating shaft; one end of the connecting rod and the other end of the rocker form a revolute pair; the supporting assistive device is fixedly installed on the connecting rod, and the other end of the supporting assistive device or the connecting rod and the crank form a revolute pair; and the first lead screw adjusting mechanism is used for adjusting the swinging center of the rocker. By means of the supporting assistive device, the local freedom degree can be eliminated, the ankle joints on the two sides can generate a certain movement angle, proper ankle pump movement is formed, the good ankle joint training effect is achieved, and the posture of the supporting assistive device is adjusted by adjusting the swing center of the rocker.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a crank rocker type limb training device. Background technique [0002] At present, my country's population is aging and the number of patients with unhealthy limbs is increasing. Therefore, assistive devices for limb rehabilitation have become a research hotspot in the field of rehabilitation. Various rehabilitation robots designed by domestic and foreign research teams have also been put into practical use. [0003] In the existing limb rehabilitation training device, the movement angles of the other joints except the knee joint are small during the rehabilitation training process, and the surrounding muscle groups cannot achieve the expected rehabilitation training effect; the existing limb rehabilitation training device does not consider the training of the human ankle joint demand, or no ankle joint training function is set, it will also cause the ankle joint not to...
