[0002] Patients suffering from rheumatoid arthritis usually have inconvenient joint movements. Traditional joint rehabilitation training devices mostly adopt stepped adjustment methods such as gears. Such a design often brings a stuck-like pain to the joints of patients.

[0003] In view of this, we propose a stepless adjustment rehabilitation activity training device that can avoid the stuck pain and can also conveniently adjust the activity range of joints. Summary of the Invention

[0004] Aiming at the defects in the prior art, the present invention provides a joint activity trainer that is convenient for adjusting the activity range to achieve stepless speed regulation and reduce the discomfort of patients.

[0005] A joint activity trainer that is convenient for adjusting the activity range provided by the present invention includes: a connecting part, there are two connecting parts, and the connecting part includes an upper connecting head and a lower connecting chuck; a flexible group belt, there are two flexible group belts, and one is detachably connected to the upper connecting head; the other flexible group belt is detachably connected to the lower connecting chuck; and a driving part, both ends of the driving part are fixedly connected to the upper connecting head and the lower connecting chuck respectively, and drive the lower connecting chuck to move; the driving part includes an intermediate driving main block, not less than one connecting driving block and a stepless driving component; the stepless driving component is installed in the intermediate driving main block; one end of the connecting driving block is rotatably installed on the intermediate driving main block and is in transmission connection with the driving group; the other end of the connecting driving block is connected to the lower connecting chuck; the upper connecting head is installed on the intermediate driving main block.

[0006] Further, the flexible group belt includes an outer flexible belt, the outer flexible belt is made of a flexible material and is filled with liquid inside. In actual use, the purpose of this design is to reduce the joint discomfort of rheumatism patients. Through the comfort of the liquid, the discomfort caused by direct contact is effectively reduced. Moreover, the flexible material used is silicone material, which further reduces the discomfort.

[0007] Further, the flexible band further includes a magnetic fluid mesh sleeve, which is arranged inside the outer flexible band and is evenly distributed in a mesh shape; wherein the magnetic fluid mesh sleeve includes an outer mesh sleeve, magnetic fluid, and an inner wire; the outer mesh sleeve covers the inner wire, and the magnetic fluid is arranged between the outer mesh sleeve and the inner wire. In actual use, the purpose of this design is not only to support the outer flexible band; but also to effectively provide support during the rehabilitation of joint activities when the patient wears and uses it, ensuring the support for the patient's body.

[0008] Further, the outer mesh sleeve is made of rubber material and can be folded and bent together with the inner wire; when the inner wire is energized, the magnetic fluid is adsorbed on the inner wire. In actual use, on the one hand, the use of rubber material enables the achievement of the folding and bending effect; in this way, it can further meet the flexibility requirements of the overall flexible band; greatly satisfying the actual needs and facilitating wearing; and on the other hand, the design of the inner wire adsorbing magnetic fluid after being energized is to strengthen the inner wire, and its purpose is to change the magnetic fluid from a fluid state to a solid state; in this way, it can effectively ensure the support for the outer mesh sleeve, making the outer mesh sleeve become solid in the fixed state of the magnetic fluid, effectively realizing the support of the magnetic fluid mesh sleeve, changing the outer mesh sleeve from a flexible state to a solid state, so that it can further effectively support the outer flexible band in the flexible band, changing from a flexible state to a solid support effect, effectively meeting the support for the joint part, enabling solid support when rotation is required, and flexible fitting when no turning of the joint is needed, avoiding the discomfort of rigid contact to the joint. Moreover, the design of injecting liquid inside further ensures the effective fitting effect on the patient. At the starting state, that is, the initial state of joint activity training, this liquid-filled design also avoids the axial pushing feeling of rigid contact abutment, but provides a feeling of facing support.

[0009] Further, the middle driving main block is provided with a rotating groove, and there are two connecting driving blocks.

In practical applications, the purpose of this design is to achieve a driving effect. The magnetic connection design adopted is to achieve the effect of stepless transmission while realizing transmission. In this way, the transmission of the connecting driving block is realized through the magnetic connection inside the magnetorheological fluid sleeve.

[0012] Further, the stepless driving assembly further includes a driving electromagnet block; the driving electromagnet block is fixedly installed on the rotating shaft of the driving motor, the driving electromagnet block is provided with a charging section and an electromagnetic section, a battery is arranged in the charging section and is electrically connected to the electromagnetic section; the electromagnetic section is magnetically connected to the magnetorheological fluid sleeve and drives the connecting driving block to rotate under the drive of the magnetorheological fluid sleeve. In practical applications, in order to realize the rotation of the connecting driving block, the driving electromagnet block design adopted, on the one hand, after charging, the power is maintained, and then the electromagnetic section can be powered on. After the electromagnetic section generates magnetism, it magnetically connects to the magnetorheological fluid in the magnetorheological fluid sleeve; in this way, when the driving motor rotates, it can drive the rotation of the driving electromagnet block; and the rotating driving electromagnet block continues to drive the magnetorheological fluid sleeve and the connecting driving block fixed thereto to rotate; of course, the driving motor adopted is a stepper motor.

[0013] As can be seen from the above technical solutions, the beneficial effects of a joint movement trainer for facilitating the adjustment of the movement range provided by the present invention are as follows:

[0014] (1) In practical applications, the flexible group belt adopted reduces the discomfort of patients;

[0015] (2) At the same time, the connecting part design adopted, which is connected up and down respectively, corresponds to the two arms of the knee joint; in this way, it is convenient to adjust the movement range of the knee joint of rheumatism patients; and the driving part drives the connecting part to perform corresponding movements.
