Embodiment 1

[0046] Such as figure 1 To the walking assist device shown in Figure 4, including the following:

[0047](1) The device includes a waist wearing assembly 1 , a hip joint energy storage mechanism 2 , a swing connector 3 , a knee joint rotating assembly 4 and a calf wearing assembly 5 . Wherein, the waist wearing assembly 1 is used for binding the hip joint energy storage mechanism 2 on the waist of the user 6, see figure 1 with 2 , comprising a waist retainer 11, a controller 12, a waist binding belt 13, an adjustment belt 14, a rotating shaft 15 and a hem bracket 16, the hip joint energy storage mechanism 2 is fixedly connected to the waist wearing assembly 1, including a cam 21, a swinging machine Frame 22, push rod mechanism 23, angle sensor 24 and luminous ring 25, push rod mechanism 23 includes roller 231, roller shaft 232, spring guide rod 233, spring 234 and spring preload knob 235, angle sensor 24 includes magnet 241, electric The magnetic sensor 242 and the sensor f...

Embodiment 2

[0056] Such as Figure 5 , shown in Fig. 6 (a), Fig. 6 (b), differs from Embodiment 1 in that the cam 21 is an inner cam, and the cam 21 is provided with a cam groove 211 matching the inner contour line, and the roller 231 is installed on the side of spring guide rod 233, and is arranged in the described cam groove, and described roller 231 is kept in contact with the inner contour line of cam 21 by force sealing mode under spring 234 spring force and does not disengage. As shown by the dotted line in Fig. 6(a), when the lower limb on the wearing side is on the heel ground at the end of the swing phase, the flexion angle of the lower limb is 30° at this time, and the walking assist device starts to absorb the consumption of the lower limb from the swing phase to the support phase. Dispersed mechanical energy, the swing plate frame 22 and the push rod mechanism 23 installed on it are driven by the swing connector 3 to rotate around the center of rotation of the cam 21. At this ...

Embodiment 3

[0058] Such as Figure 7 , shown in Fig. 8 (a), Fig. 8 (b), differ from Embodiment 1 in that the cam 21 is formed by an eccentric installation of a circular wheel body. In this example, the center of rotation of the roller 231 is installed on the spring On the central axis of the guide rod 233, as shown by the dotted line in Fig. 8(a), when the lower limb on the wearing side is in the heel-ground at the end of the swing phase, the flexion angle of the lower limb is 30° at this time, and the walking assist device begins to absorb the movement of the lower limb. The oscillating phase transfers to the dissipated mechanical energy of the supporting phase, the oscillating plate frame 22 and the push rod mechanism 23 installed on it rotate around the center of rotation of the cam 21 under the drive of the oscillating connector 3, and the roller 231 moves from the cam 21 to the actual The starting point of the profile begins to rotate along the cam push section, the center distance b...

Abstract

A walking assist device includes a hip-joint energy storage mechanism, a wear component for binding a fixed portion of the hip-joint energy storage mechanism to the waist of a user and enabling a rotation center of the hip-joint energy storage mechanism to coincide with a rotation center of a hip joint, and a swinging connection member for connecting a movable portion of the hip-joint energy storage mechanism with a knee-joint rotation assembly, wherein the knee-joint rotation assembly is provided with a calf wearing assembly for facilitating fixing of the knee-joint rotation assembly on a lower leg, and the rotation center of the knee-joint rotating assembly coincides with the rotation center of a knee joint. The walking assist device disclosed by the invention can solve the problems thatexisting walking assist devices are complicated in system, heavy in weight, bad in wear comfort and high in cost, and are not conducive to mass application and the like.

Description

technical field [0001] The invention relates to the technical field of human walking assisting equipment, in particular to a walking assisting device. Background technique [0002] A walking assist device is a mechanical device or an electromechanical system that is worn on the outside of the human body to assist the recovery of the human walking function and enhance the muscle endurance of the human lower limbs. Hip assist is one of the most effective ways of sports rehabilitation for hemiplegic gait induced by spinal cord injury, stroke, etc. In addition, the human hip joint lacks the muscle-ligament tissue enriched by the ankle joint, which is not conducive to the effective movement of energy. Absorption and utilization, the walking assistance device with hip joint assist has a more significant assisting efficiency than the ankle joint assist walking assist device. Currently, the hip joint design of walking assistance devices mostly adopts active driving methods such as ...
