Embodiment

[0075] The flexible silk of this embodiment adopts flexible silk.

[0076] Such as figure 1 , figure 2 As shown, the device is a flexible wire driving device with a clutch, the double flexible wire can be controlled separately, and the elastic device is pre-tightened, and the stroke can be adjusted. The flexible wire driving device mainly includes a reduction motor mechanism 200, a clutch mechanism 300 , the flexible wire rope wheel mechanism 400 , the elastic pretensioning device 500 , the deceleration limit mechanism 600 , and the total mounting plate 101 .

[0077] Such as Figure 4 As shown, the reduction motor mechanism 200 includes a motor reduction unit 201 , a torque adapter plate 202 , a driving gear 204 and an adapter ring 205 . The motor deceleration unit 201 already includes components such as a DC motor, a harmonic decelerator, and an encoder. The motor reduction unit 201 is transferred and fixed on the general mounting plate 101 through an adapter ring 205 ....

Abstract

The invention relates to a flexible wire drive device which comprises a gear motor mechanism, a clutch mechanism, flexible wire wheel mechanisms and an elastic pre-tightening device. The flexible wirewheel mechanisms comprise flexible wire wheels. The flexible wire wheels are used for fixing one ends of flexible wires and are fixed to clutch shafts of the clutch mechanism and driven by the clutchshafts to rotate. The clutch mechanism is in engaged connection with the output end of the gear motor mechanism. Whether the clutch mechanism and the gear motor mechanism are engaged or not is controlled through on-off of a clutch of the clutch mechanism, and therefore on-off of torque transmission of the gear motor mechanism and the flexible wire wheels is controlled. The elastic pre-tighteningdevice is a torsion elastic device, the twist center of the elastic pre-tightening device is fixed, and the twist outer portion of the elastic pre-tightening device is fixedly connected with the flexible wire wheels. According to the flexible wire drive device, it can be guaranteed that a driven execution mechanism does not achieve self locking, the flexible wire wheels can be pre-tightened and cannot be wound, and the stroke range of the execution mechanism can be further adjusted.

Description

technical field [0001] The invention relates to the technical field of flexible wire driving, in particular to a flexible wire driving device. Background technique [0002] Rehabilitation and robotic devices that are part of the actuator are, for the most part, light weight, small and low complexity. For this type of rehabilitation equipment, it is generally required that in the event of a problem with the equipment, the system is not self-locking after the power is turned off, and the patient can act on his own to ensure personal safety. In addition, for rehabilitation equipment or wearing exoskeleton equipment for different patients, it is necessary to adjust the stroke range of the actuator for different limb lengths. [0003] The flexible wire driving method can place the driving mechanism remotely, and the power is transmitted to the actuator through the flexible wire, so that the actuator can be light in weight, small in size, simple in structure, and easy to maintain...
