Walking assistance device

Abstract

A walking assistance device includes a first rod, a second rod, a power unit, and a transmission rope. The second rod is rotatably connected to the first rod. The power unit is disposed on one side of the first rod and away from the rotary joint between the first and second rods. The transmission rope is connected to both the power unit and the second rod. In an active mode, the power unit is activated, stretching the transmission rope to create tension, thereby causing the second rod to rotate relative to the first rod. In a passive mode, the power unit is deactivated, and the transmission rope is slack.

Claims

1. A walking assistance device, comprising: The first member; A second member, rotatably connected to the first member; A power assembly is disposed on one side of the first link and away from a rotary joint between the first link and the second link; A transmission rope is provided, which connects the power unit and the second rod respectively. In an active mode, the power unit is activated and stretches the transmission rope to a taut state to drive the second rod to rotate relative to the first rod. In a passive mode, the power unit is deactivated and the transmission rope is slack.

2. The walking assistance device as claimed in claim 1, wherein the power assembly has a motor, a gearbox, a turntable and a battery pack, the motor is fixed to the first member, the gearbox is connected to the motor, the turntable is rotatably disposed in the gearbox, and the battery pack is located near the rotary joint between the first member and the second member and coupled to the motor.

3. The walking assistance device as claimed in claim 2, wherein the second rod has a fixing block, and a fixed end of the transmission rope is connected to the fixing block located on the battery pack.

4. The walking assistance device as claimed in claim 2, wherein the transmission rope has a loop and a bolt, a fixed end of the transmission rope is connected to the second rod, the loop is connected to a drive end of the transmission rope away from the second rod, the loop is disposed on the turntable, and the bolt passes through the loop and is screwed onto the turntable.

5. The walking assistance device as claimed in claim 4, wherein the turntable is adapted to rotate relative to the gearbox along a centerline, stretching the transmission rope through the bolt and the collar, while the collar rotates along the bolt.

6. The walking assist device as claimed in claim 4, wherein when the turntable rotates to a first position, the bolt and the collar move away from the battery pack and stretch the transmission rope, and when the turntable rotates to a second position, the bolt and the collar move closer to the battery pack and loosen the transmission rope.

7. The walking aid device as claimed in claim 4, wherein the collar is disposed on an outer edge of the turntable away from the center.

8. The walking assistance device as claimed in claim 1, wherein the first member has two first uprights, a first curved rod and a first strap, the two first uprights are arranged parallel to each other, the first curved rod is vertically connected to the two first uprights and away from the swivel joint between the first member and the second member, and the first strap is laterally disposed between the two first uprights.

9. The walking assistance device as claimed in claim 8, wherein the second rod has two second upright rods, a second curved rod and a second strap, the two second upright rods are arranged parallel to each other and pivotally connected to the two first upright rods respectively, the second curved rod is vertically connected to the two second upright rods and is away from the swivel joint of the first rod and the second rod, and the second strap is laterally disposed between the two second upright rods.

10. The walking aid device as claimed in claim 1, wherein the transmission rope is made of cotton or elastic material.
