Electric toys such as toy cars and toy planes played by children are equipped with rechargeable batteries. Charge. In general, manufacturers are equipped with mains chargers, but when people are in the wild and cannot obtain mains power, they cannot charge, and because they are charged by mains power, they need to consume energy. Chinese patent 200520063253.X discloses a hand generator, but this machine is only used as a hand generator for students to learn, but it is very inconvenient to hold, and it cannot be used as a device for charging rechargeable batteries. use.

Contents of the invention

The purpose of the utility model is to provide a hand-held hand-operated generator that is easy to hold and operate, easy to use, and can provide charging power.

The purpose of this utility model is achieved through the following technical solutions.

A hand-held hand-operated generator, including a housing, a hand crank, a speed-increasing gear mechanism, and a generator. The hand crank is located outside the housing. The generator includes a stator, a rotor, a brush, and an output electrode. The output electrode and the output The wire is connected, the hand crank is connected with the speed-increasing gear mechanism, and the speed-speed gear mechanism is connected with the rotor in the generator. It is characterized in that: a handle is provided on the side opposite to the hand crank on the outside of the housing.

One end of the handle is provided with a rotating shaft, the handle is mounted on the housing through the rotating shaft, and the handle can rotate 360° around the rotating shaft in positive and negative directions.

The housing is composed of an upper cover and a lower cover, and one end of the lower cover is provided with a receiving cavity, and the generator is installed in the receiving cavity.

The speed-increasing gear mechanism includes a driving bull gear I, a driven pinion I, a driven pinion II, and a driven pinion III. The driven pinion I is coaxially connected with the rotor in the generator, and the driven pinion II There is a driving bull gear II coaxially connected, and a driving bull gear III is coaxially connected with the driven pinion III. III and the driving gear III are respectively installed on a support plate through the rotating shaft, the driving gear I meshes with the driven pinion III, the driving gear III meshes with the driven pinion II, and the driving gear II and the driven pinion The I phase meshes to form a three-stage speed-up mechanism.

The middle part of both sides of the housing is provided with an observation oil injection window, and a window cover is arranged on the observation oil injection window.

The free ends of the wires are connected with plug connectors.

The plug connector is provided with a USB interface.

Compared with the prior art, the utility model has the following advantages:

In the utility model, a grip handle is provided on the side opposite to the hand crank on the outside of the housing, especially one end of the grip handle is provided with a rotating shaft. Rotate, so that people can hold the handle with one hand, and shake the handle with the other hand to generate electricity by hand, so it is convenient for hand-held operation and easy to use. Especially the speed-up gear mechanism is a three-stage speed-up mechanism, and the output power can fully meet the needs of the charging power supply.

Since the free end of the wire is connected with a plug connector, and the plug connector is provided with a USB interface, the charging of most small electrical appliances can be used universally, and the use is more convenient.

The utility model is particularly suitable for small electrical appliances such as mp3, mobile phones, cameras, flashlights, and electric toys such as toy cars and toy airplanes.
