the first surface of the shell is hermetically bonded with the backlight surface of any one solar cell panel, the size and the shape of the first surface are the same as those of the backlight surface, and the first surface is the bottom surface of the box body and is arranged opposite to the cover plate.

Further, in the above technical scheme, the casing comprises a box body and a cover plate, a plurality of clamping blocks are arranged at the edge of the cover plate, clamping grooves corresponding to the clamping blocks one to one are formed in the box body, and the through holes are formed in the top surface of the box body.

Furthermore, the first surface and the cover plate are both provided with reinforcing rib frames, and the reinforcing rib frames are arranged inside the shell.

Further, in the above technical scheme, still be provided with charge indicator, interface and power key on the second surface of portable power source body, charge indicator, charge-discharge interface and power key all are connected with the PCB board controller electricity.

The utility model has the beneficial effects that: the solar charging component is composed of a plurality of solar cell panels which are connected in series and are light in weight, and when the solar charging component is not charged, the solar cell panels are folded to reduce the occupied area, and the solar charging component is unfolded when in use. Due to the preparation process of the solar cell panel, the solar cell panel is characterized by thick middle and thin edges, the shape and the size of the first surface of the shell are consistent with those of the solar cell panel, better sealing and attractive effects can be obtained after the shell is fixed by the sealant, and the connection stability between the solar charging component and the mobile power supply body is effectively improved. Be equipped with the through-hole on the first surface, positive negative pole on the solar cell panel is directly connected with the battery electricity after the through-hole, avoids additionally setting up solar charging interface again.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 1-2, a solar mobile power supply includes a solar charging assembly and a mobile power supply main body bonded to the solar charging assembly.

The solar charging component comprises a plurality of solar cell panels 1 connected in series, wherein the backlight surface of one solar cell panel 1 is fixedly bonded with the first surface of the mobile power supply main body, the light receiving surface of each solar cell panel 1 is placed under sunlight during use, and the solar cell panels 1 are stacked after charging is finished.

The solar cell panel 1 can be specifically prepared by sequentially laminating a front film layer, an adhesive film layer, a solar cell sheet layer, an adhesive film layer and a substrate through hot pressing, wherein the front film layer can be a fluorine-containing polymer film, so that the weather resistance of the solar cell panel 1 can be improved, and the weight of the solar cell panel 1 can be reduced. In addition, in order to improve the appearance of the solar panel 1, a back surface of the solar panel 1 may be painted or an outer material may be bonded.

The solar panels 1 are connected through a flexible connecting band, and wires of the solar panels connected in series can be hidden in the connecting band.

The mobile power supply main body mainly comprises a box body 2, a battery 5, a PCB controller 4 and a cover plate 3, wherein a plurality of clamping pieces 31 are arranged on the edge of the cover plate 3, clamping grooves 21 which are in one-to-one correspondence with the clamping pieces 31 are arranged on the box body 2, and after the clamping pieces 31 and the clamping grooves 21 are buckled, the box body 2 and the cover plate 3 form a shell; the battery 5 and the PCB controller 4 are disposed within the housing. In order to avoid that the inside device of casing receives the extrusion, set up strengthening rib frame 6 on

apron

3 and 2 bottom surfaces of box body, can effectively improve the intensity of casing, strengthening rib frame 6 is located inside the casing.

In order to improve the use safety of the solar cell, the size of the solar cell is smaller than that of the front film layer and the substrate, so that the prepared solar cell panel 1 is thick in the middle and thin at the edges.
