Technical Field

[0001] The utility model relates to a roll-type flexible battery sheet, belonging to the technical field of solar battery sheets. Background Art

[0002] Flexible solar cells, a type of thin-film solar cell, are an emerging technology in the solar industry. They consist of a layer of resin-encapsulated amorphous silicon as the primary photovoltaic element, laid flat on a flexible substrate. They are characterized by their bendability and portability. To make flexible solar cells even more convenient, roll-up flexible solar cell chargers are now available on the market. These flexible solar cells are rolled up and stored in a compact volume.

[0003] However, when in use, the flexible battery sheet body is exposed to sunlight in an unfolded form, and the light-receiving surface of the flexible battery sheet body is completely exposed to the air. After long-term use, fine dust particles in the air will fall on the surface of the flexible battery sheet body. When the flexible battery sheet body is rolled up again, the dust will be rolled up together and pressed into the flexible battery sheet body. Over time, the flexible battery sheet body is easily scratched. Now, a roll-type flexible battery sheet is urgently needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3The utility model provides a technical solution: a scroll-type flexible battery sheet, including a support seat 1, a fixed strip 7 and a cleaning cotton strip 15. The support seat 1 is provided with two, and ball bearings 2 are installed on the upper ends of the two support seats 1. A reel 3 is installed between the inner rings of the two ball bearings 2, and a hand wheel 4 is installed at the front end of the reel 3. The flexible battery sheet body 5 is rolled up on the outside of the reel 3, and a strip pull block 6 is provided at the movable end of the flexible battery sheet body 5. The fixed strip 7 is fixed between the two support seats 1, the fixed strip 7 is located at the lower right end of the flexible battery sheet body 5, and a strip groove 8 is opened at the right end of the fixed strip 7. A plurality of return springs 11 are installed at the upper end of the strip groove 8, and a spring connecting piece 12 is installed horizontally at the lower end of the plurality of return springs 11. The cleaning cotton strip 15 is in the strip groove 8, and a Velcro hook surface 14 is installed on the upper end of the cleaning cotton strip 15.

[0019] As the first embodiment of the present invention: the left and right sides of the upper ends of the two support seats 1 are provided with mounting grooves. The added mounting grooves make it easy for the staff to use external bolts to pass through the support seats 1 to fix them. The right end of the strip groove 8 is installed with a cover 9 by means of a hand screw 10. The added cover 9 can shield the right side of the multiple reset springs 11 and the cleaning cotton strip 15. The lower end of the spring connecting piece 12 is fixed with a Velcro surface 13 by epoxy resin glue. The lower end of the Velcro surface 13 is adhered to the Velcro hook surface 14. The lower end of the added Velcro surface 13 is adhered to the Velcro hook surface 14, thereby facilitating the disassembly and cleaning of the cleaning cotton strip 15. The size of the strip groove 8 is larger than that of the strip pull block 6. When the added strip pull block 6 is pulled, the flexible battery sheet body 5 can be pulled to unfold.

[0020] As a second embodiment of the present invention: when the flexible battery sheet body 5 is unfolded and needs to be reeled in (at this time, the flexible battery sheet body 5 passes through the strip groove 8, and due to the arrangement of multiple return springs 11, it will push down the cleaning cotton strip 15 through the spring connecting piece 12, the Velcro fur surface 13 and the Velcro hook surface 14, and the upper surface of the flexible battery sheet body 5 is in close contact with the cleaning cotton strip 15, and the lower end surface of the flexible battery sheet body 5 is in contact with the lower end of the inner side of the strip groove 8), the left hand turns the hand wheel 4 to drive the reeling shaft 3 to rotate, and the rotation of the reeling shaft 3 will drive the flexible battery sheet body 5 to reel in. During this process, the flexible battery sheet body 5 moves to the left in the strip groove 8, and under the tight push of multiple return springs 11, the special structure of the lower end of the cleaning cotton strip 15 will be used to clean and intercept the dust on the upper surface of the flexible battery sheet body 5 (reference Figure 3 ), ensure the cleanliness of the flexible battery sheet body 5 when it is rolled up. After the cleaning cotton strip 15 has been used for a long time, the two hand screws 10 can be unscrewed, and then the blocking cover 9 can be removed, and then the Velcro fur surface 13 and the Velcro hook surface 14 can be separated to realize the disassembly of the cleaning cotton strip 15, thereby facilitating its subsequent cleaning.
