Generator with enclosed liquid vesicle for shoes

Abstract

The invention discloses a shoe power generation device provided with closed liquid bags, which comprises a rotor and a stator, wherein, the rotor is arranged in a cavity, and is provided with a rotary core which can drive the rotor to rotate, the rotary core is provided with a driven transmission part; the cavity is provided with at least two hollow pipes one ends of which are connected with liquid bags, the inside of at least one of the hollow pipes is provided with a piston, the piston is connected with a driving transmission part corresponding to the driven transmission part; the hollow pipes, the liquid bags and the cavity form a closed cavity, working liquid medium is stored in the closed cavity, and the piston divides the working liquid medium into mutually independent spaces. The invention takes advantage of the hydraulic transmission principle, abandons the gear speed-increasing transmission mechanism which is widely used in the prior power generation device and has larger volume, but takes advantage of the presssurized flow of the working liquid medium to push the piston to drive the rotor of the generator to rotate, thereby achieving the power generation and greatly reducing the volume of the power generation device. The power generation device has the characteristics of simple structure, small volume, low cost, stability and high efficiency.

Description

technical field [0001] The invention relates to a power generation device, in particular to a power generation device for shoes with a sealed liquid bag which is used in shoes and uses the change of gravitational potential energy when the human body walks to obtain electric energy. Background technique [0002] In the process of walking, people need to constantly change their own gravitational potential energy. If it is not used, it will be wasted. If the power generation device that can convert potential energy into electric energy can be installed on the shoes, then these energy can be converted into electric energy and utilized or stored. Such as dotted lights on children's shoes, colored flash lights on skates, heating insoles in shoes, etc. At present, the power generation devices used in shoes are basically realized by using speed-increasing gear sets and matching micro-generators. Compared with the shoes that people usually wear, the shoes with power generation devic...

Problems solved by technology

At present, the power generation devices used in shoes are basically realized by using speed-increasing gear sets and matching with micro-generators. Compared with the shoes that people usually wear, the shoes with power generation devices are relatively larger in weight and volume. The comfort is poor, not quite in line with people's habit of wearing shoes

[0003] Chinese patent 92209633.3 discloses a portable airbag transmission power generation and storage device, which uses air pressure or hydraulic pistons to drive the generator rotor to rotate and generate electricity. If airbags are added in the cylinder, although the leakage can be alleviated, due to its poor sensitivity, it is difficult to deal with reciprocating and alternating movements at high speeds, resulting in greater impact or abnormality. Work

At present, micro-turbine generators suitable for assembly into shoes on the market have not yet entered mass production, and their high prices have prevented such micro-turbine generators from being widely used.
