The embodiments provided by the present invention will be further described in detail below with reference to the accompanying drawings.

Referring to FIG. 1, a solar charging device 100 provided by the present invention includes III-V. The family solar cell module 10, the collecting lens 20 and the bracket 30.

The III-V solar cell module 10 includes a body 11, a III-V solar cell wafer 12, and a charge control circuit 13 having an output.

The body 11 is generally square in shape, and the III-V solar cell wafer 12 is disposed at a geometric center of the surface of the body 11 for receiving sunlight and converting it into electrical energy. The charging control circuit 13 having an output terminal is disposed in the body 11 and electrically connected to the III-V solar cell wafer 12 for transmitting the electric energy generated by the III-V solar cell wafer 12 to convert solar energy. The charging control The output of circuit 13 is used to connect to the outside world to output electrical energy. It can be understood that the III-V solar cell wafer 12 can also be disposed elsewhere on the surface of the body 11.

A plurality of first positioning holes 40 are disposed around the III-V solar cell wafer 12 on the body 11. In this embodiment, each of the first positioning holes includes two positioning holes, which are symmetrically disposed on the body. Both sides of the III-V solar cell wafer 12. It can be understood that each of the first positioning holes 40 may further include three or more positioning holes, which are uniformly disposed around the III-V solar cell wafer 12.

The condensing lens 20 is mounted above the III-V solar cell wafer 12 via the holder 30. The concentrating lens 20 is a circular Fresnel lens for collecting sunlight directed to the III-V solar cell wafer 12 to increase the output power of the III-V solar cell module 10. It can be understood that the concentrating lens 20 can also be a flexible concentrating lens or other kind of concentrating lens, and its shape is not limited to a circular shape.

The bracket 30 includes two pillars, and both ends of the two pillars are provided with an external thread structure. Two uniformly distributed internal thread structures are disposed at the periphery of the collecting lens 20 The second positioning hole 50. One end of the support post 30 is screwed into the second positioning hole 50 of the collecting lens 20, and the other end is screwed onto the body 11 of the III-V solar cell module 10 to correspond to the collecting lens. In the first positioning hole 40, the concentrating lens 20 is mounted above the III-V solar cell wafer 12 in this manner.

It can be understood that the number of the pillars of the bracket 30 and the second positioning holes disposed around the condenser lens 20 may be more than two, and the pillars of the bracket 30 and the collecting lens 20 and the III-V solar energy The fixing manner of the body 11 of the battery module 10 is not limited to the screwing. For example, the two ends of the pillar and the positioning hole may be directly inserted into the positioning hole without providing a thread structure. fixed.

In the present embodiment, the solar charging device 100 includes a plurality of collecting lenses (20, 20b, ...) each having a different collecting magnification, and the use of each of the collecting lenses produces a different power output. A second positioning hole is disposed on a periphery of each of the collecting lenses (20, 20b, ...), and the second positioning holes of each of the collecting lenses are aligned with the plurality of groups disposed on the body 11 A set of holes corresponds to each other. The bracket 30 mounts a corresponding concentrating lens above the III-V solar cell wafer 12 through the corresponding first positioning hole and the second positioning hole according to different power output requirements. As shown in FIG. 2, when the solar charging device 100 needs to change the power output, it is only necessary to replace the concentrating lens 20 of FIG. 1 with a concentrating lens 20b having another concentrating multiple, which is then required. The concentrating lens 20b is erected to the III-V group by a first positioning hole 40b provided on the body 11 corresponding to the condensing lens 20b and a second positioning hole 50b disposed around the condensing lens 20b.
