Abstract

The invention discloses an energy-saving device capable of realizing recycling power generation of motion energy. The energy-saving device comprises exercise fitness equipment, a generator, a charging device, an energy storage device, an inverter and a control device, wherein the exercise fitness equipment is electrically connected with the generator; the generator is electrically connected with the charging device; the charging device is electrically connected with the energy storage device; the energy storage device is electrically connected with the inverter; the control device is connected with the charging device, the energy storage device, the inverter, an alternating current power supply and a load respectively; the alternating current power supply is connected with the load; the output end of the inverter is connected with the input end of the load. The energy-saving device disclosed by the invention is simple in structure and can automatically realize operation; the power generation amount can be automatically adjusted according to the size of the load; the energy-saving device can independently run on the basis of a power grid and does not convey electric energy to the power grid so as to avoid grid-connection power generation; the electric energy is self-generated and self-used; therefore, the electric energy can be finally saved, and the torque of the generator can be adjusted in real time according to the force of a user, so that the users with different degrees of force enables the generator to generate power by using the fitness equipment.

Description

technical field [0001] The invention relates to an energy-storage and power-generating fitness device, in particular to an energy-saving device for realizing exercise energy recovery and power generation and a control method thereof. Background technique [0002] With the improvement of people's living standards, indoor sports and fitness equipment has become common. The user converts their own kinetic energy into the mechanical potential energy of the sports fitness equipment during use, and the mechanical potential energy of the sports fitness equipment can only be converted into thermal energy for consumption. service life, but also caused a waste of energy. [0003] To this end, some technicians provide a device that can convert a user's kinetic energy into electrical energy through a sports fitness equipment and a generator and store it. For example, Chinese patent document CN101934126B discloses "an energy-storage power-generating fitness device", which includes spor...

AI Technical Summary

Problems solved by technology

Although this device can convert the kinetic energy of the user into electrical energy, it needs manual operation to apply it to the load after recovering the energy and generating electricity, and it cannot automatically adjust the output power according to the power required by the load. When the energy cannot support the normal operation of the load, the AC power cannot be automatically activated, which makes it easy to suspend the work due to insufficient power during the use of the load, which affects people's normal use

[0004] In addition, because the torque of the existing generators is generally constant during use, and the strength of users who use sports and fitness equipment is uneven, the generator may not be able to start when the strength is small, and the power of the generator is relatively large. In the process of use, there will be energy waste, and if the torque of the generator is adjusted manually with different users, this will increase the workload of the user, and the adjustment process will be more cumbersome.
