Description

Technical Field

[0001] The utility model belongs to the technical field of solar cells, and in particular relates to a flexible perovskite solar cell charging backpack. Background Art

[0002] As an almost inexhaustible green energy source, solar energy has broad application prospects. However, the large size, heavy weight and strong rigidity of traditional solar panels limit their widespread application in portable devices. Especially for users who need to spend a long time outdoors, such as hikers and explorers, they are eager to have an energy solution that is both lightweight and self-sufficient.

[0003] As one of the indispensable equipment in outdoor activities, the design of backpacks is constantly developing in the direction of multi-function and lightweight. Combining solar panels with backpacks can not only make full use of the free space on the surface of the backpack and improve the efficiency of solar energy collection, but also add additional power support to the backpack to meet the user's need to charge electronic devices during outdoor activities. However, the existing solar panels are not convenient to carry. When combined with backpacks for use, users cannot flexibly choose whether to install solar panels according to different environments and needs, so as to achieve the purpose of preventing damage in the jungle and lightweighting the backpack when traveling on rainy days. Therefore, the practicality is poor. Utility Model Content

When used in combination with a backpack, the user cannot flexibly choose whether to install the solar panel according to different environments and needs, thereby preventing damage in the jungle and lightweighting the backpack when traveling on rainy days.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: a flexible perovskite solar cell charging backpack, comprising a backpack main body, an upper expansion patch and a lower expansion patch are sewn at intervals on the upper and lower sides of the rear side of the backpack main body, a current storage and control component is embedded in one side of the backpack main body, the current storage and control component includes a battery, a photovoltaic controller and a power output and input interface, binding belt components are sewn on the backpack main body on the upper and lower sides of the upper expansion patch, the binding belt components are adapted to be bound to the outside of the perovskite solar cell, the perovskite solar cell includes a solar panel and a hinge, and adhesive patches are provided at the upper and lower ends of the perovskite solar cell, and the adhesive patches are adapted to bond the upper expansion patch and the lower expansion patch.

[0006] The beneficial effects of the utility model are as follows: the perovskite solar cell can be quickly unfolded and stably fixed through the bonding of the upper expansion sticker, the lower expansion sticker and the adhesive sticker, so as to convert sunlight into electrical energy for collection and utilization; the perovskite solar cell can be effectively stored and folded under the binding of the binding belt assembly to avoid scratches; the perovskite solar cell can be conveniently removed from the backpack body to ensure the lightweight carrying effect of the backpack body.

[0007] In order to effectively store and reduce the volume of perovskite solar cells;

[0008] As a further improvement of the above technical solution: the number of the solar panels is multiple, and the hinge rotatably connects two adjacent solar panels.

[0009] The beneficial effect of this improvement is that the solar panel can be rotated with the support of the hinge, so that it can be unfolded to generate electricity, or folded and stored to prevent the perovskite solar cell from being scratched when people walk through the jungle.

[0010] In order to ensure the stability of the perovskite solar cell installed on the backpack body after the perovskite solar cell is unfolded;

[0011] As a further improvement of the above technical solution: the adhesive patch and the upper expansion patch and the lower expansion patch are all Velcro structures.

[0012] The beneficial effect of this improvement is that the connection method of the Velcro structure enables the perovskite solar cell to be quickly and conveniently removed from the backpack body while maintaining the stability of the installation.

[0013] In order to enable the folded perovskite solar cell to be firmly bound and fixed by the binding belt assembly;

[0014] As a further improvement of the above technical solution: the binding strap assembly includes an elastic band and a quick-connect buckle, the elastic band is sewn and fixed to the backpack body on the upper and lower sides of the upper expansion patch, and the quick-connect buckle is clamped on the end of the elastic band, and the quick-connect buckles arranged on the upper and lower elastic bands are adapted to be clamped to each other.

[0015] The beneficial effect of this improvement is that with the cooperation of the elastic band and the quick-connect buckle, the perovskite solar cell is firmly bound between the backpack body and the binding belt assembly.

[0016] In order to ensure the stability of the binding tape assembly on the perovskite solar cell;

[0017] As a further improvement of the above technical solution: the number of the binding strap assemblies is two, and they are arranged on the backpack body on the left and right sides opposite to each other.

[0018] The beneficial effect of this improvement is that the two sets of binding belt assemblies can respectively bind and fix the left and right ends of the perovskite solar cell to ensure the stability of the installation of the perovskite solar cell.

[0019] In order to stably collect and utilize the electricity generated by perovskite solar cells;

[0020] As a further improvement of the above technical solution: the lead connector of the perovskite solar cell is electrically plugged into the power output and input interface of the current storage and control component, and the current storage and control component is electrically connected to the perovskite solar cell.

[0021] The beneficial effects of this improvement are as follows: the solar panels generate current when exposed to sunlight, and the photovoltaic controller in the current storage and control component regulates and controls the current and voltage generated by the solar panels, which are then output to the battery in the current storage and control component for storage. When the operator uses a charging cable to plug into the power supply interface on the current storage and control component, the battery's electrical energy is stably supplied to the electrical equipment.

The perovskite solar cell 3 can be quickly unfolded and stably fixed by bonding the upper expansion sticker 4, the lower expansion sticker 6 and the adhesive sticker 33, so as to convert sunlight into electrical energy for collection and utilization; the perovskite solar cell 3 can be effectively stored and folded under the binding of the binding belt assembly 5 to avoid scratches; the perovskite solar cell 3 can be conveniently removed from the backpack body 1 to ensure the lightweight carrying effect of the backpack body 1. The number of the solar panels 31 is multiple, and the hinge 32 is rotatably connected to two adjacent solar panels 31. The solar panel 31 can be rotated with the hinge 32 as the support, so as to unfold and generate electricity, or fold and store to avoid scratching the perovskite solar cell 3 when people walk through the jungle. The adhesive sticker 33 and the upper expansion sticker 4. The lower expansion patch 6 is a Velcro structure. The connection method of the Velcro structure enables the perovskite solar cell 3 to be quickly and conveniently removed from the backpack body 1 while maintaining the stability of the installation. The binding belt assembly 5 includes an elastic band 51 and a quick-connect buckle 52. The elastic band 51 is relatively sewn and fixed to the backpack body 1 on the upper and lower sides of the upper expansion patch 4. The quick-connect buckle 52 is clamped on the end of the elastic band 51. The quick-connect buckles 52 set on the upper and lower elastic bands 51 are mutually adapted and clamped. With the cooperation of the elastic band 51 and the quick-connect buckle 52, the perovskite solar cell 3 is firmly bound between the backpack body 1 and the binding belt assembly 5.
