Detailed ways

Below in conjunction with accompanying drawing 1 to accompanying drawing 4 the present invention will be further elaborated:

Embodiment one:

A manual power generator charger as shown in Figure 1 includes a housing composed of an upper housing 1 and a lower housing 2, a generator 3, a transmission gear set 4, an actuating part 5 and a charging socket 6, and the generator 3 And the transmission gear set 4 is arranged in the cavity of the lower casing 2, the actuating part 5 is arranged outside the casing and connected with the transmission gear set 4, the transmission gear set 4 drives the generator 3 to rotate through the gear transmission, and the manual generator charger also A rechargeable battery 7 is included, and the rechargeable battery 7 is fixedly arranged in the cavity of the lower casing 2 and is electrically connected with the generator 3 , and the charging socket 6 is electrically connected with the rechargeable battery 7 .

As shown in Figure 1, in order to achieve the purpose of increasing the speed, the transmission gear set 4 usually adopts a gear speed-up mechanism with more than two stages. In the present invention, a gear speed-up mechanism with four stages is used, and in order to reduce the volume of the product, the first The axes of rotation of the driving wheel of the first stage, the driven wheel of the second stage and the driving wheel of the third stage coincide in a straight line; for a straight line.

Since the charging line of the current portable electronic product is generally connected to the charging power supply using a USB connection, in order to improve the adaptability of the product, in this embodiment, the charging socket 6 is an output USB interface.

As shown in Fig. 1 and Fig. 2, the actuating part 5 is a crank, and the crank includes a handle 511, a rotating arm 512 and a rotating disk 513, and the rotating disk 513 is fixedly connected with the first-stage driving wheel of the transmission gear set 4. In the embodiment, the rotating disc 513 and the first-stage driving wheel are integrally formed, and one end of the rotating arm 512 is movably connected to the rotating disc 513, as shown in Figure 1, the rotating disc 513 corresponds to the rotating arm 512 A round hole is provided at the position, and the rotating disc 513 and the rotating arm 512 are connected by connecting pins through the above-mentioned round hole, and the rotating arm 512 can be turned over 180° along the connecting pin axis; the other end of the rotating arm 512 is fixedly connected with the handle 511 , the handle 511 can drive the rotating disk 513 to rotate 360°. The rotating disc 513 is driven by shaking the handle 511, thereby driving the transmission gear set 4 to rotate, and the generator 3 converts the mechanical energy generated by the gear rotation into electrical energy, stores it in the rechargeable battery 7 or charges the portable electronic product through the charging socket 6.

As shown in Figure 3, in order to facilitate portability and reduce the space occupied by the handle 511, the lower housing 2 is provided with a lower recess 21. When the manual power generator charger is not in use, the rotating arm 512 can be turned 180° along the connecting axis. The handle 511 is then rotated into the lower recess 21 .

Embodiment two:

The difference between the present embodiment and the first embodiment is that the first embodiment uses a manual method to drive the transmission gear set 4 to rotate, while the present embodiment uses a pressing method to drive the transmission gear set 4 to rotate. In this embodiment, only the parts different from those in the first embodiment are described, and the same parts will not be described in detail again.

As shown in Figure 4, the actuating part 5 is a pressing handle, and the pressing handle includes a handle 521, a tooth plate 522, and an elastic element 523. The handle 521 is fixedly connected to one end of the tooth plate 522, and the other end of the tooth plate 522 One end is provided with teeth and the first-stage drive wheel of the transmission gear set 4 is engaged with each other through the teeth, and the elastic element 523 is arranged inside the handle 521 . In this way, when the handle 521 is pressed, the elastic element 523 can be compressed and the tooth plate 522 can be driven to move. The tooth plate 522 and the first-stage driving wheel can drive the transmission gear set 4 to rotate when the tooth plate 522 meshes with the first-stage driving wheel. When the handle 521 moves to the end, the handle is released. 521, due to the elastic force of the elastic element 523, the handle 521 can rebound to the original position, so that the reciprocating motion makes the transmission gear set 4 rotate continuously, and the generator 3 converts the mechanical energy generated by the gear rotation into electrical energy, and stores it in the The portable electronic product is charged in the rechargeable battery 7 or through the charging socket 6 .

The above-described embodiments are only preferred examples of the present invention, and are not intended to limit the scope of the present invention, so all equivalent changes or modifications made according to the structure, features and principles described in the patent scope of the present invention should be Included in the patent application scope of the present invention.
