detailed description

Below in conjunction with accompanying drawing, specific embodiment of the present utility model is described in detail.

A foot-operated self-generator, as shown in Fig. 1 and Fig. 2, includes a casing 1, a motion conversion mechanism 2, a gear transmission mechanism 3, a flywheel accumulator 4, an alternator 5 and a storage battery 6.

Motion conversion mechanism 2, including pedal 21, bearing 22 and arc rack 23;

The gear transmission mechanism 3 includes a large gear 31 and a small gear 32;

The pedal 21 is arranged on the outside of the shell 1, and the pedal 21 is axially connected with the arc rack 23 through the bearing 22, the bearing 22 is arranged on the shell 1, the arc rack 23, the gear transmission mechanism 3, the flywheel accumulator 4, and the alternator 5 and battery 6 are arranged inside the housing 1, the arc rack 23 meshes with the bull gear 31, the bull gear 31 meshes with the pinion 32, the flywheel accumulator 4 is installed on the pinion 32, and the pinion 32 and the alternator The rotor of 5 is meshed, and the output terminal of alternator 5 is connected to battery 6 .

A buffer spring 24 is arranged below the pedal 21 . The storage battery 6 is connected with a USB interface.

The working process of the above-mentioned foot-operated self-generator is as follows:

When the user steps on the pedal 21, the pedal 21 is pressed down, and the pedal 21 drives the arc-shaped rack 23 to move through the bearing 22. After the gears mesh, the gears of the gear transmission mechanism 3 and the gears of the alternator 5 start to move in sequence, and the gear transmission mechanism 3 drives the rotor of the alternator 5 to cut the magnetic field lines to generate electric energy. When the foot is lifted, the pedal 21 bounces back to the original position under the action of the buffer spring 24, and the arc rack 23, the gear transmission mechanism 3 and the alternator 5 The gear moves in the opposite direction to generate a reverse current. The large gear 31 meshes with the pinion 32, which increases the speed and improves the power generation efficiency. The flywheel accumulator 4 is installed on the pinion 32, and the pinion 32 drives the rotor of the alternator 5 Speed adjustment and energy storage are performed during rotation and power generation.

The internal circuit diagram of the alternator is shown in FIG. 3 , and a first diode, a second diode, a third diode and a fourth diode are connected between the alternator 5 and the storage battery 6 .

The positive pole of the alternator is connected to the positive pole of the first diode and the negative pole of the second diode, and the negative pole of the alternator 5 is connected to the positive pole of the third diode and the negative pole of the fourth diode. The negative pole of the pole tube and the negative pole of the third diode are connected to the positive pole of the storage battery 6, and the positive pole of the second diode and the positive pole of the fourth diode are connected to the negative pole of the storage battery 6;

During the charging process, the voltage generated by the alternator 5 is Ec, and the current from the alternator 5 flows to the storage battery 6 after being rectified by D1~D4. Uo.

At the same time, the foot-operated self-generator will generate certain noise due to the operation of the gears during work, so sound-absorbing materials are embedded inside the shell 1, and the sound-absorbing material is made of slag wool, thereby greatly reducing the noise of the foot-operated self-generator. Suitable for indoor use.
