technical field

The present invention relates to a charging device, and more specifically relates to an emergency charging device, which can be used to charge batteries of mobile phones and other equipment.

Background technique

Taking mobile phone chargers as an example, the power of ordinary chargers comes from the mains AC.

Detailed ways

A preferred implementation diagram of the present invention is shown in Fig. 1 to Fig. 12 . In addition to the rectification circuit and charging circuit in the traditional charger, the emergency charging device 1 is also provided with a small manual generator. As can be seen from the figure, the manual generator consists of a handle 4, a plurality of gears 5 and A small alternator is composed of 7; the three are mechanically connected in turn, when the handle is pushed by an external force, the internal gear can be driven to rotate, and the rotation speed between each gear is gradually increased, so that the last gear rotates at a high speed and drives the AC generator The rotor of the machine rotates at a high speed. The rotor is a circular gravity magnet. Its magnetic field lines move relative to the outer coil to generate electricity. It is also a flywheel with inertial motion, so as to achieve the purpose of power generation. The rectification circuit and the charging circuit are all mature prior art, so they will not be described one by one here. When working, the rectification circuit rectifies and filters the alternating current sent by the manual generator to output direct current to the charging circuit; the charging circuit outputs charging voltage to the internal storage battery 3 or the external battery to be charged.

As shown in Figure 4a, when the push handle is pressed down, the spring 12 is also compressed, and the internal gear rotates, and a clutch gear 13 moves down and rotates and drives the gear 14 to rotate the rotor 15 of the generator.

As shown in Figure 4b, when the handle is released, the inner spring 12 of the device will rebound and push back the handle, and at the same time drive the gear to rotate in the opposite direction, and the clutch gear 13 rotates and moves upward, so that the clutch gear 13 and the gear 14 separates, but is driven by the inertial rotation of rotor 15 and continues to keep rotating.

As shown in FIG. 1 , a solar panel 2 is installed on the shell surface of the emergency charging device 1 , and the power output terminal of the solar panel is connected to the input terminal of the charging circuit. When the device is placed in sunlight, the solar panel can output DC power to the charging circuit. That is to say, the device can use solar energy to output charging voltage to the internal storage battery 3 or the external battery to be charged.

As shown in Figure 6, the device is also provided with a storage battery power display circuit, which is composed of a power display switch 13 and four light-emitting diodes 14. The ground lights up to indicate how much power is left in the internal storage battery of the device. When the storage battery is fully charged, all four LEDs will be on at the same time, but when the storage capacity is only about 50%, only two LEDs will be on.

In the emergency charging device, a lighting circuit can also be added, specifically, it can be composed of a lighting switch and a lighting lamp, wherein the lighting lamp can be composed of one or more light-emitting diodes connected in series or in parallel. In this way, the device can be used as a small lighting flashlight.

This device can selectively transmit the power generated manually to the storage battery in the device or directly output it to the equipment that needs to be charged. When charging, the power of the storage battery can be used to charge the external battery, or the power generated by the manual generator can be directly output to the external battery for charging after rectification, filtering, and voltage stabilization.

Fig. 10 shows an example when the device of the present invention is mounted on a power output socket. FIG. 11 shows an example in which the device charges a mobile phone 9 through a connector 11 and a wire 10 . Fig. 12 shows an example of realizing the lighting function directly through manual power generation when the internal storage battery is out of power.
