Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0028] like figure 1 , figure 2 As shown, an exoskeleton-type finger rehabilitation training device for realizing the joint drive of the active / passive driver includes two parts: the feedback driver and the finger exoskeleton mechanism, wherein the feedback driver includes a base plate 11 and a right bracket fixed on the base plate 11 9. The housing composed of the left bracket 10 and the baffle plate 8 is fixed at one end of the right bracket 9 to generate a magneto-rheological fluid damper 2 for damping force, and at the other end of the right bracket 9 is fixed an encoder used as an angle sensor 1. The motor 3 used to provide power is fixed at one end of the left bracket 10, the magneto-rheological fluid damper 2 is connected to the running wheel 5 through the right coupling 4, and the motor 3 is connected to the running wheel 5 through the left coupling 6, The encoder ...

Abstract

The invention discloses an exoskeleton type finger rehabilitation training device driven by an active driver and a passive driver together. The exoskeleton type finger rehabilitation training device driven by the active driver and the passive driver together comprises a force feedback driver and a finger exoskeleton mechanism, wherein the force feedback driver comprises a shell body, a motor and a magnetorheological fluid damper, a rotary wheel is connected between the motor and the magnetorheological fluid damper through a coupler, a hauling cable is wound on the rotary wheel, the finger exoskeleton mechanism comprises a support, a linear guide rail and a finger fixing structure, a sliding block is arranged on the linear guide rail and is connected with the hauling cable, a first connecting block is fixed on the sliding block, an L-shaped crank is connected at the lower end of the first connecting block in a rotary mode, a middle finger knuckle block is connected at the other end of the crank in a rotary mode, and the other end of the middle finger knuckle block is connected on the finger fixing structure through a second connecting block. Due to the fact that the finger exoskeleton mechanism is a slider-crank mechanism similar to a plane four-bar mechanism, a given law of movement can be achieved, and the exoskeleton type finger rehabilitation training device driven by the active driver and the passive driver together is light in movement and high in transmission efficiency.

Description

technical field [0001] The invention relates to an exoskeleton type finger rehabilitation training device for realizing combined driving of a main / passive driver. Background technique [0002] The human hand is one of the most vulnerable parts of the body. Hand trauma accounts for a large proportion of trauma cases. According to the survey, the proportion of hand trauma is 15.0% to 28.6%. Due to the relatively fine structure of the hand and small muscles all over the hand, the treatment of hand injuries requires high requirements and is very difficult. However, my country lacks corresponding single-finger rehabilitation treatment equipment, resulting in many hand trauma patients not being able to receive rehabilitation in a timely manner. Therefore, single-finger rehabilitation plays an increasingly important role in the entire rehabilitation medicine system. [0003] The function of the hand is accomplished through the flexible movement of the fingers, and the movement d...
