Description

Foldable Solar Charger

technical field

The utility model relates to a foldable solar charger.

Background technique

As a clean energy source, solar energy is becoming more and more popular. Previously there were only large, stationary solar chargers that converted solar energy into other forms of energy for use. Now with the development of technology, solar chargers are becoming smaller and smaller, and can even be carried around to charge mobile phones. However, the existing small solar chargers are bulky, the whole set of devices is relatively thick, and the number of solar silicon crystal panels cannot be increased. The electrical connection between the solar silicon crystal panels in each sub-housing is to install a battery at the corresponding position of each sub-housing. The metal sheet, when the shell is opened, the metal sheet of the sub-housing contacts to make the solar silicon crystal panels in each sub-housing form a loop. This way is very easy to poor contact, and very easy to damage.

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in further detail. The above and other objects, features and advantages of the present invention will be apparent to those skilled in the art from the detailed description of the present invention.

Description of drawings

Fig. 1 is the structural representation of preferred embodiment of the utility model;

Fig. 2 is an exploded schematic view of sub-housing components.

Detailed ways

Below in conjunction with accompanying drawing, the utility model will be further described.

The preferred embodiment of the utility model is shown in Fig. 1 and Fig. 2, a solar silicon crystal panel 1 and a housing 3, and the solar silicon crystal panel 1 is arranged in the housing 3; the housing 3 includes three interconnected and foldable sub-housings 2; As shown in Figure 2, a slider fixing part 21 is provided on the side wall of the inner cavity of the sub-housing 2. The slider fixing part 21 is made of plastic, of course, it can also be made of rubber that will not scratch the solar silicon crystal panel. 1 material. Slider fixture 21 fixes solar silicon crystal panel 1 on the sub-housing 2, so just needn't use the sub-housing structure of traditional box lid/box bottom, but only needs to use box bottom and vertically extend along box bottom side wall The slider fixing member 21 can fix the solar silicon crystal panel 1 in the casing 3, which reduces the thickness of the box body, and simultaneously makes the structure simpler and reduces the cost.

Simultaneously, in the preferred embodiment of the utility model, the solar silicon crystal panel 1 anode and cathode are positioned at the side 1 edge of the solar silicon crystal panel, and the sub-housing 2 is provided with a wire 4, as shown in Figure 2, the wires 4 are respectively connected to the solar silicon crystal panel The positive and negative poles of 1 electrically connect the solar silicon crystal panels 1 in each sub-housing 2 to form a loop. In this way, there is no need to reserve a space at the bottom of the sub-housing for accommodating the wires 4 and solder joints, the sub-housing 2 can be made thinner, and the thickness of the sub-housing can be further reduced.
