Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 Shown is the exercise pedal generator vehicle of the present invention, which includes a motion input part, a DC generator and a storage battery, the motion input part is connected to the generator input shaft, and the DC generator is connected to the storage battery through a charging circuit.

[0020] Such as image 3 , the main inventive point of the present invention is that the storage battery is connected to the excitation coil of the DC generator through an excitation current regulation circuit, and the excitation current regulation circuit includes a voltage regulation circuit and a discharge resistor R, and its function is to change the DC generator excitation through the voltage regulation circuit , thereby changing the electromagnetic torque to adjust the resistance of the bicycle. The voltage regulating circuit can adopt ...

Abstract

The invention relates to a pedal power-generating car and aims to solve the problem that energy loss of prior pedal power-generating cars is large in the aspects of changing resistance and braking. The pedal power-generating car comprises a motion input portion, a direct-current generator and a storage battery, the motion input portion is in a transmission connection with a generator input shaft, the direct-current generator is connected with the storage battery through a charging circuit, the storage battery is connected with a magnet exciting coil of the direct-current generator through a magnet exciting current adjusting circuit, and the magnet exciting current adjusting circuit comprises a voltage adjusting circuit and a discharge resistor. The pedal power-generating car has the advantages that the energy utilization rate is high, the electrodeless adjustment can be achieved, the continuous change of resistance can be achieved, the adaptability and comfort of fitness are greatly improved, the pedal power-generating car has double values of fitness and power generation energy storage recycle, and the market prospect is wide.

Description

technical field [0001] The invention relates to a bicycle for fitness. Background technique [0002] The pedal generator is a kind of bicycle exercise and fitness equipment, which adopts the transmission structure and shape similar to that of a bicycle, so that people can carry out bicycle fitness training without leaving home. The pedal dynamo itself has a DC generator and a storage battery. The motion input part of the pedal dynamo is connected to the input shaft of the DC generator, and the output of the DC generator is used to charge the battery. The energy provided by the athlete can be stored in the battery for lighting. , audio and other secondary uses. [0003] Some existing pedal bikes also have a resistance changing function, such as setting different gears by adding a friction holster to increase the resistance. Different gears correspond to different resistances. People can choose the most suitable for themselves when training. Power gear. In addition, an exte...
