Problems solved by technology

[0004] 1. The suspended lower limb medical robot has certain requirements on the health of the patient's upper limbs, and has a certain training burden on the patient's upper limbs;
[0005] 2. There are too few movement modes that can be realized by seat-type lower limb medical robots, and rehabilitation exercises are not suitable for human kinematics;
[0006] 3. The treatment effect of the horizontal lower limb medical robot is relatively poor, and the mechanical arm directly drives the lower limb movement instead of assisting the patient in rehabilitation exercise
[0007] 4. The control system used to control the lower limb rehabilitation medical robot in the prior art, when the upper computer is operated for a long time, the signal frequency band of the wireless transceiver module is unstable, causing the upper computer to be unable to control the motor movement, and the data and signal transmission will be interrupted at any time. At this time, it is necessary to reset the transceiver module to transmit, which leads to some accidents and insufficient convenience

Embodiment 1

[0047] Such as Figure 1-Figure 8 As shown, a lower limb rehabilitation device provided in this embodiment includes a base 4 and side support bases 11 welded on both sides of the top of the base 4. The middle position of the top of the side support base 11 is equipped with a support column 6 through a screw rod. The support column 6 The end far away from the base 4 is equipped with a seat 2 through a screw, the side of the seat 2 is provided with a chair back 1, the middle part of the inner side of the side support seat 11 is provided with a thigh mechanical arm, and the end of the thigh mechanical arm is provided with a calf mechanical arm , and the end of the calf mechanical arm is provided with a pedal 7, the top of the base 4 and the back of the side of the seat back 1 are provided with a seat back adjustment assembly for adjusting the angle of the seat back 1, and the side support seat 11 is provided with a seat for adjusting the first The outer tube 10 rotates the thigh ...

Embodiment 2

[0065] Such as Figure 9 As shown, a method for controlling a lower limb rehabilitation device, applied to a single-chip microcomputer, includes the following steps:

[0066] S1: MCU initialization;

[0067] S2: Start the rehabilitation action and collect action signals; specifically, obtain the rehabilitation action through the attitude sensor and convert it into attitude data;

[0068] S3: Send the attitude data to the data transponder; specifically, the attitude data is sent to the data transponder through the communication module;

[0069] S4: Convert the attitude signal and send it to the host computer for display; specifically, the data transponder converts the attitude data into an attitude signal and sends it to the host computer for display

[0070] S5: Determine whether the action is over; specifically, determine whether the data obtained by the attitude sensor reaches the final action data of the rehabilitation action, for example, the final action of the thigh mo...

Abstract

The invention discloses a lower limb rehabilitation device and a control method thereof, and belongs to the technical field of lower limb rehabilitation devices. According to the lower limb rehabilitation device, advantages of three different types of lower limb rehabilitation robots are combined, and complementary mutual assistance is provided to indirectly make up for shortcomings of the three different types of lower limb rehabilitation robots. Compared with the existing three main types of robots, the lower limb rehabilitation device can reduce a disadvantage of excessive burden on an upper limb of a patient during a treatment process, is closer to human kinematics and plays an auxiliary motion role instead of purely driving patients to perform lower limb movements. Compared with ordinary rehabilitation equipment, the lower limb rehabilitation device has more comprehensive functions, simple operation, and can achieve basic requirements for rehabilitation movements, so as to achievea purpose that the patient is able to complete rehabilitation training independently. Moreover, an nRF24l01 wireless transmission module is used for stable transmission.

Description

technical field [0001] The present invention relates to a rehabilitation device, in particular to a lower limb rehabilitation device, and also to a control method, in particular to a control method of a lower limb rehabilitation device, which belongs to the technical field of lower limb rehabilitation devices. Background technique [0002] The existing lower limb rehabilitation medical robots are mainly divided into three main types: suspension type, seat type, and supine type. Among them, the suspension type uses structures such as elastic bands to lift the upper limbs of the human body to reduce the weight of the lower limbs. At the same time, the lower limbs are worn Types of exoskeletons used to assist in therapy. The sitting type is for the patient to sit directly on the treatment chair, and the leg mechanical arm is used to drive the lower limbs to perform auxiliary therapeutic movements. [0003] The defects of the lower limb rehabilitation medical robot in the prior...
