Embodiment 1

[0030] Such as Figure 1-4 As shown, a dynamic feedback automatic adjustment lower limb rehabilitation robot includes a seat 1. The seat 1 is provided with a soft cushion 2. The top of the soft cushion 2 is provided with a pillow 3. The rehabilitation device for patients with bone injuries is combined with the seat 1. In the recovery process like this, the patient can sit and stand on the soft cushion 2, or lie on the soft cushion 2 and the pillow 3, which reduces the support of the patient's hands, reduces the burden on the patient's body, and increases the leg training of the patient The length of time, thereby ensuring the rapid recovery of patients.

[0031] The left and right armrests of the seat 1 are provided with a group of first joints 5, one end of the first joint 5 is connected to the seat plate 4 fixed on the seat 1, and the other end of the first joint 5 is movably connected with a second joint 8, and the second joint 8 The two joints 8 are provided with rotating...

Embodiment 2

[0034] The applicant has found in practice that the above-mentioned solution still has the following problems: some patients’ legs can only be lifted at a small angle due to limb stiffness, and if the biaxial motor 61 still rotates to drive the first joint 5 or the second joint 8 When rotating, not only is it easy for the patient to bear a large force, causing secondary damage, but also due to the reaction force of the patient's legs, the biaxial motor 61 will be blocked, causing the motor to burn out or reduce its lifespan. In order to solve this problem, the biaxial motor 61 of the present application is electrically connected to the governor, and the governor monitors the output current of the biaxial motor 61 in real time. , the output current of the biaxial motor 61 gradually increases. In order to effectively protect the patient during the process of lifting the legs, a feedback threshold is set for the output current monitoring value of the biaxial motor 61. When the out...

Embodiment 3

[0036] In order to adapt to patients with different leg lengths, the extension bar 9 includes a slide plate 93, and the inner side of the second joint 8 is provided with a movable groove, and the slide plate 93 is sleeved in the movable groove, and two slide bars 94 are interspersed on the slide plate 93. The upper and lower ends are respectively fixedly connected with the upper and lower sides of the inner wall of the movable groove, the slide bar 94 is sleeved with a downward pressure spring 95, the outer side of the slide plate 93 is fixedly connected with a connecting plate 92, and the bottom end of the connecting plate 92 is fixedly connected with a foot bar 91 . Due to the influence of the patient's sitting posture and the length of the legs, the patient can step down on the pedal 10 as needed, so that the extension rod 9 can move down on the slide bar 94 and squeeze the depressing spring 95. In such a process On the one hand, the length of the extension rod 9 can be adj...

Abstract

The invention relates to the technical field of lower limb robots, and discloses a dynamic feedback automatic adjustment lower limb rehabilitation robot. The lower limb rehabilitation robot comprisesa seat; the seat is provided with a soft seat cushion; the top part of the soft seat cushion is provided with a back cushion; armrests of the seat are each movably connected with a first joint; and one side of each first joint is movably connected with a second joint. According to the application scheme, through a regulating device, the first joints or the second joints can be selected to rotate with a dual-axis motor, and thus, vertical swing training is carried out on thighs or shanks, and meanwhile, synchronous stretching training can be performed on left and right thighs or shanks, or alternative stretching training can also be performed on the left and right thighs or shanks, so that a variety of combined training methods are realized, the rehabilitation effect is more significant, and the lower limb rehabilitation robot widely adapts to different patients.

Description

technical field [0001] The invention relates to the technical field of lower limb robots, in particular to a dynamic feedback automatic adjustment lower limb rehabilitation robot. Background technique [0002] At present, traditional rehabilitation training is generally labor-intensive, especially gait rehabilitation, which requires at least three therapists to manually assist patients to complete leg and trunk exercises. Medical staff are not only labor-intensive, but also difficult to ensure stable and continuous exercise training. The lower limb rehabilitation training robot is mainly aimed at patients with lower limb motor dysfunction, and its main function is to help patients with lower limb motor dysfunction complete various motor function rehabilitation training processes. At present, lower limb rehabilitation robots have been put into clinical use. However, the current rehabilitation equipment is far from meeting the intelligent and ergonomic requirements for patie...
