Problems solved by technology
[0004] 1. Due to the use of a large number of sensors, electrical components, circuit boards and motors, the circuit is more complicated;
[0005] 2. Due to the need to be supported by electricity during use, battery life must be considered. If carrying a power supply will increase the load, direct power supply will greatly limit the range of activities of the user;
[0006] 3. There will be certain noise pollution when the motor and related electrical parts are working;
[0007] 4. The cost of motors, electrical components and chips is relatively high;
[0008] 5. Although this system can adapt to most people who need it, it is too cumbersome and complicated for those who only need a small amount of assistance

Embodiment 1
[0037] Such as figure 1 , 2 As shown, a mechanical walking assist device of the present invention is composed of a spring pressing rod 1, a thigh support rod 2 and a calf support rod 3 to form a frame.
[0038] Foot pedal 4, foot support spring 5, foot housing bottom 6, rack 11 and ratchet 12 are a foot mechanism, which are integrally encapsulated in the foot housing to provide a source of power for the entire booster system.
[0039] Spring pressing bar 1, thrust spring 7, thigh bracket 13 and thigh support bar 2 form the mechanism of energy storage and conversion, and are the parts of absorbing energy and outputting energy.
[0040] The steel wire rope 9, the support wheel 8 and the support wheel 10 are the energy transmission parts, which are the media for the conversion of kinetic energy and potential energy.
[0041] The overall motion process of the mechanical walking assist device is, for example, figure 1 Shown, people's state when bending one's leg, now thigh suppo...

The invention relates to the technical field of sports rehabilitation, and discloses a mechanical walking assist device, comprising: a spring compression rod (1), a thigh support rod (2), a calf support rod (3), a thrust spring (7) and a thigh bracket (13 ), wherein, the spring bar (1), thigh support bar (2) and calf support bar (3) form a frame; the spring bar (1), thrust spring (7), thigh bracket (13) It forms an energy storage and conversion mechanism with the thigh support rod (2), which is used for absorbing energy and outputting energy. The invention adopts a simple mechanical assisting structure, which converts the work done by gravitational potential energy into kinetic energy to assist people in walking; since only the mechanical structure does not use electric power, it avoids the load, duration and range limitations of power distribution for people's walking .
Description
technical field [0001] The invention relates to the technical field of sports rehabilitation, in particular to a simple mechanical walking assist device. Background technique [0002] At present, the existing walking assist systems basically use sensors and chips to judge the posture of the human body, and the motor provides power for assisting. [0003] The above-mentioned walking assist system has the following disadvantages: [0004] 1. Due to the use of a large number of sensors, electrical components, circuit boards and motors, the circuit is more complicated; [0005] 2. Due to the need to be supported by electricity during use, battery life must be considered. If carrying a power supply will increase the load, direct power supply will greatly limit the range of activities of the user; [0006] 3. There will be certain noise pollution when the motor and related electrical parts are working; [0007] 4. The cost of motors, electrical components and chips is relativel...
