[0038] like Figures 1 to 4 As shown, some embodiments of the present invention disclose a portable solar photovoltaic suitcase, comprising a suitcase 1, a concentrating photovoltaic unit 2, and a USB interface assembly 3. The suitcase 1 comprises a main body 11 and a lid 12, with a focusing lens 121 disposed on the upper portion of the lid 12. The concentrating photovoltaic unit 2 is fixed to the main body 11 or the lid 12, for example, by being fixed to the rear side wall of the main body or to the lid via a fixing rod, and the light incident end face of the concentrating photovoltaic unit 2 faces the focusing lens 121. The USB interface assembly 3 is electrically connected to the concentrating photovoltaic unit 2 and disposed on the upper side wall 111 of the main body 11. By disposing the focusing lens 121 on the lid 12, more light energy is absorbed within the same area. The focusing lens 121 acts as a primary focus, and in conjunction with the secondary focus of the concentrating photovoltaic unit 2, effectively increases the optical reception angle, improves the energy storage rate, and enhances the user experience.

[0039] The portable solar photovoltaic suitcase disclosed in some embodiments of the present invention, based on the above embodiments, comprises a concentrating photovoltaic unit 2 comprising a concentrating bracket 21, a secondary concentrator 22, and a photovoltaic cell 23. The secondary concentrator 22 is disposed within the concentrating bracket 21, with the light incident end face of the secondary concentrator 22 facing the focusing lens 121, and the light emitting end face of the secondary concentrator 22 connected to the photovoltaic cell 23, which is connected to the USB interface assembly 3. By configuring the secondary concentrator 22 as a secondary concentrating structure, the light emitting end face of the secondary concentrator 22 cooperates with the photovoltaic cell 23 in the receiver to transmit light to the photovoltaic cell 23. Furthermore, in this embodiment, the concentrating bracket 21 may include a heat sink base 211, a bracket body 11212 of the main body 11, and a light-reflecting coating 213 disposed on the inner wall of the bracket body 11212 of the main body 11. The lower end of the bracket body 11212 of the main body 11 is fixed to the heat sink base 211, forming a semicircular cavity with an opening 214 at the upper end. The light-incident end face of the secondary concentrator 22 is exposed through the opening 214. During use, the focusing lens 121 first focuses light from different angles and then transmits it to the secondary concentrator 22. The light-reflecting coating 213 can reflect most or substantially all of the light that escapes from the secondary concentrator 22 back to the secondary concentrator 22, thereby improving the light utilization efficiency and power generation of the concentrating photovoltaic unit 2. The overall structure is relatively simple and easy to manufacture.

[0040] In some embodiments of the portable solar photovoltaic suitcase disclosed herein, based on the aforementioned embodiments, the secondary concentrator 22 is a cylindrical structure with a circular cross-section, and its diameter gradually decreases from the light incident end face to the light exit end face. The secondary concentrator 22 is preferably made of a rotating quartz light guide rod to achieve optimal light transmission efficiency.

[0041] The portable solar photovoltaic suitcase disclosed in some embodiments of the present invention, when fixed to the body, may further include a protective cover 215 to prevent damage or contamination to the light incident end face of the secondary concentrator 22 during the opening of the case 1. The protective cover 215 is mounted on the opening 214 to protect the light incident end face of the secondary concentrator 22. The protective cover 215 is generally a chain-like structure, for example, a plurality of long strips connected by hinges or other means to form a flexible structure that is rigid in one direction and can be rolled up and stored in the other direction. When unfolded, it covers the entire opening 214 to provide shielding. When rolled up, it can be stored on one side of the opening 214, and can even be folded and attached to the outer wall of the bracket body 11212 of the body 11. There are various connection methods. The protective cover 215 listed in this embodiment has one side hinged to the bracket body 11212 of the body 11, and the other side is connected to the bracket body 11212 of the body 11 by a snap. The structure for fastening the cover body by snapping can be implemented in a manner commonly used in the prior art. As long as the protective cover 215 can be snapped onto the opening 214 in an openable manner, those skilled in the art should know how to achieve this connection, which will not be described in detail here. Furthermore, in order to prevent the protective cover 215 from opening and causing it to shake inside the box body 1 when the box body 1 is closed, the position of the protective cover 215 can also be fixed when the opening 214 needs to be exposed. Specifically, a fixing can be provided on the outer wall of the bracket body 11212 of the main body 11. When the protective cover 215 is opened to expose the opening 214, the other side of the protective cover 215 is fixed to the fixing. The fixing can be a buckle, etc., and the other side of the protective cover 215 is fixed to the buckle, etc. by a buckle head, a connecting buckle, a connecting hook, etc., which will not be described in detail here.

[0042] The portable solar photovoltaic suitcase disclosed in some embodiments of the present invention, based on the above-described embodiments, has a sealing ring 13 disposed around the inner periphery of the focusing lens 121 located on the inner side of the case lid 12. In a first state, the case lid 12 is mounted on the body 11, the protective cover 215 is opened to expose the opening 214, and the other side of the sealing ring 13 abuts against the periphery of the opening 214, thereby forming a seal between the focusing lens 121 and the light-emitting end face of the secondary concentrator 22. The purpose of providing the sealing ring 13 is to ensure a clean and sealed environment between the inner side of the focusing lens 121 and the light-entering end face of the secondary concentrator 22, thereby preventing adverse effects on light transmission. In addition, a lens shield 14 is provided on the upper part of the box cover 12. The lens shield 14 can be detachably mounted on the focusing lens 121. Generally, the lens shield 14 can be installed on the box cover 12 by a push-pull sliding installation method. Specifically, two slides can be provided on the box cover 12. The two side walls of the lens shield 14 can slide in the two slides respectively. When the lens shield 14 slides to the first position, the focusing lens 121 is covered and protected. When the lens shield 14 slides to the second position, the focusing lens 121 is exposed, thereby achieving better light absorption performance.

[0043] Thus far, various embodiments of the present disclosure have been described in detail. To avoid obscuring the concept of the present disclosure, some details well known in the art have not been described. Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.

[0044] Although some specific embodiments of the present disclosure have been described in detail through examples, those skilled in the art will understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present disclosure. Those skilled in the art will understand that the above embodiments may be modified or some technical features may be replaced with equivalents without departing from the scope and spirit of the present disclosure. In particular, as long as there are no structural conflicts, the various technical features mentioned in the various embodiments may be combined in any manner.
