Problems solved by technology

Most of the existing lower limb rehabilitation robots do not have a pelvic mechanism. Patients are greatly restrained during the training process and cannot move their bodies freely. The importance of balance training for the rehabilitation of hemiplegic patients is ignored, which affects the rehabilitation process.

Embodiment 1

[0017] see attached figure 1 , a pelvic mechanism for gait rehabilitation training, comprising a base (1), two rockers (2), a connection box (3), a cover plate (4), a swing piece (5), Four extension shafts (6), two support plates (7) and two support arms (8); characterized in that: the rocker (2) is connected to the connection box (3) and the base (1). ) hinged, the cover plate (4) is covered on the connection box (3), the swing piece (5) is located below the lower part of the connection box (3) and is movably connected with the connection box (3), the swing piece (5) There are two adjustable extension shafts (6) on both sides of ), the extension shafts (6) are fixedly connected by a support plate (7) and a support arm (8); the base (1) is connected with the robot, It can move up and down along the column of the robot to realize the degree of freedom of up and down movement at the pelvis; the connection box (3) can be swayed left and right around the base (1) through the rock...

Embodiment 2

[0019] see attached figure 2 and attached image 3 , this embodiment is basically the same as the first embodiment, the special feature is that the rocker (2) is hinged with the connection box (3) and the base (1) as follows: the rocker (2) ) has a hole up and down at both ends of the The rotating shaft fixed on the connection box (3) is rotated to reduce friction, and the thrust ball bearing (10) is used to bear the force in the vertical direction.

[0020] The structure in which the swing piece (5) is movably connected with the connection box (3) is: the swing piece (5) is connected with the connection box (3) through two joint bearings (11), and the upper end of the joint bearing (11) passes through A joint bearing seat (12) and a joint bearing sleeve (13) are fixed together with the connection box (3), the lower end is connected with the swing piece (5) through a locking bolt (14), and the joint bearing (11) can be wound around the center It rotates on all sides to rea...

Embodiment 3

[0023] This embodiment is basically the same as Embodiment 1 and Embodiment 2. The special feature is that: during training, the therapist assists the patient to wear the safety belt fixed to the end of the support arm (8) on the hip, and the support arm (8) is clamped on the hip. On both sides of the patient's pelvis, the patient performs various walking modes such as flat ground, steps, ramps, obstacles, etc. according to the rehabilitation needs. During the training process, the patient can move his body freely, and the pelvis needs to move up and down, left and right, and twist. , roll and pitch three rotations, the structural design of the present invention can ensure that the freedom of movement of the patient's pelvis is not restricted, the patient is training the balance ability while training the walking function of the legs, and ensures the safety of the patient and accelerates recovery process.

Abstract

The invention discloses a pelvis mechanism for gait rehabilitation training. The mechanism comprises a base, a rocker, a junction box, a cover plate, a swing member, an extension shaft, a supporting plate, a supporting arm and the like, wherein the base can move up and down along a stand column of a robot to realize the degree of freedom for vertical movement at the pelvis; the junction box can swing left and right around the base through the rocker to realize the degree of freedom for left-right movement at the pelvis of a patient; the swing member can rotate around the junction box through two joint ball bearings to meet the twist motion, roll motion and pitching motion of the pelvis. According to the pelvis mechanism, the constraint to the patient can be effectively reduced, so that the patient can freely move the pelvis, the comfort of the training process is improved, the balance capacity is trained while the lower limb walking function is trained, and a better training effect is achieved.

Description

technical field [0001] The invention relates to the field of rehabilitation medical equipment, in particular to a pelvic mechanism that can be used for gait rehabilitation training. Background technique [0002] In recent years, with the aging of the population, various unhealthy lifestyles, traffic accidents, work-related injuries, etc. have been increasing, and patients with walking dysfunction caused by stroke, spinal cord injury or accident have become a common group in modern society. In addition to the use of drugs and surgery, these patients mainly rely on physical therapy, that is, rehabilitation training. [0003] The upper part of the human pelvis is connected with the lumbar spine, and the lower part and the femur form the hip joint, which is the bridge between the spine and the lower limbs. The weight of the body is transmitted to the lower limbs through the pelvis, and the vibration of the lower limbs is also transmitted to the spine through the pelvis. It move...
