Description

Technical Field

[0001] This utility model relates to the field of charging box technology, and in particular to a solar charging box. Background Technology

[0002] A storage battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery that achieves recharging through a reversible chemical reaction. Currently, charging boxes are commonly used to charge storage batteries. However, electronic products use batteries of various specifications, and the charging compartment design of existing solar charging boxes is too simplistic, failing to adequately accommodate multiple battery sizes and thus affecting charging efficiency.

[0003] To address the aforementioned issues, patent document CN220107629U discloses a charging box with solar charging functionality. This charging box has multiple fixing bolts arranged equidistantly on one side of the box body, with a lid movably installed inside each bolt. Symmetrical through holes are provided on both opposite sides of the box body. Multiple rotating shafts are arranged equidistantly on the side of the lid connected to the fixing bolts, with their outer sides rotatably connected to the inside of the fixing bolts. A solar panel is fixedly installed on one side of the lid. A base plate is fixedly installed at the bottom of the box body, and multiple clamping assemblies are equidistantly installed on the top of the base plate. A power supply is fixedly connected to one side of the box body, and a converter is fixedly connected to the other side. Conductive plates are fixedly connected to both sides of the box body. This charging box uses multiple clamping assemblies to clamp batteries of different specifications, thus solving the technical problem of low charging efficiency caused by the battery box's inability to accommodate various battery sizes.

[0004] However, while the aforementioned charging case can accommodate various battery sizes by incorporating multiple clamping components, it requires consideration of the size and shape of different batteries when dividing the internal charging space. This necessitates reserving additional space to accommodate batteries of different sizes, which not only reduces the space utilization within the case but also increases the overall size of the charging case, resulting in poor portability. Utility Model Content

[0005] This utility model provides a solar charging box to solve the technical problems of low internal space utilization, large size and poor portability of existing charging boxes.

[0006] To solve the above problems, the solar charging box provided by this utility model adopts the following technical solution:

[0007] A solar charging box, comprising:

[0008] The main body of the charging box includes an upper shell, a connecting shell, and a lower shell that can be detachably connected from top to bottom. A solar photovoltaic panel is installed on the top surface of the upper shell.

[0009] The connecting shell has multiple partitions that divide the internal space of the connecting shell into a first mounting position and a second mounting position that are perpendicular to each other. There are multiple second mounting positions that are spaced apart. A first circuit board is installed between two adjacent second mounting positions. The first and second mounting positions are used to install nickel-metal hydride batteries.

[0010] The lower housing has a third mounting position for installing a lithium battery and a second circuit board that corresponds to and is connected to the first circuit board.

[0011] The beneficial effects of the solar charging box provided by this utility model are:

[0012] 1. By setting up a charging box body including an upper shell, a connecting shell, and a lower shell, the internal space of the charging box body is vertically divided into a first functional area enclosed by the upper shell and the connecting shell, and a second functional area enclosed by the connecting shell and the lower shell. This facilitates the clear division and efficient utilization of the functions of each part inside the charging box body.

[0013] 2. Multiple partitions are set inside the connecting shell to divide the internal space of the connecting shell, so that the originally single space is effectively divided into multiple small spaces. Each space can install batteries or circuit boards as needed, which improves the utilization rate of the internal space of the connecting shell, reduces space waste, and helps to reduce the overall size of the solar charging box and improve its portability.

[0014] Through the above-mentioned design, this utility model optimizes the internal space division of the solar charging box, effectively solving the technical problems of low internal space utilization, large size, and poor portability of the charging box in the prior art.

[0015] Furthermore, the bottom of the upper housing has a partition area that matches the first mounting position, the second mounting position, and the first circuit board.

[0016] Furthermore, both the first circuit board and the second circuit board are PCB control boards.

[0017] Furthermore, both the upper shell and the lower shell are circular, or both the upper shell and the lower shell are rectangular.

[0018] Furthermore, the connecting shell is annular.

[0019] Furthermore, the top surface of the upper housing is provided with a groove, and the solar photovoltaic panel is installed in the groove.

[0020] Furthermore, the first circuit board is located at the center of the connecting shell. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] It should be noted that the main concept of the solar charging box provided by this utility model is as follows: by setting the main body of the charging box as a structure including an upper shell, a connecting shell and a lower shell, the internal space of the main body of the charging box is divided in the vertical direction, and by setting multiple partitions in the connecting shell, the internal space of the connecting shell is divided in the horizontal direction. The originally single space is effectively divided into multiple independent small spaces in the vertical and horizontal directions, thereby improving the utilization rate of the internal space of the charging box, reducing space waste, reducing the overall volume of the solar charging box, and thus improving its portability.

[0031] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0032] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0033] Embodiment 1 of the solar charging box provided by this utility model:

[0034] like Figures 1 to 4 As shown, the solar charging box includes a charging box body, a solar photovoltaic panel 4 installed on the top surface of the charging box body, and a first mounting position 6 and a second mounting position 7 for installing nickel-metal hydride batteries, a third mounting position 9 for installing lithium batteries, a first circuit board 8 and a second circuit board 10 inside.

[0035] The following describes the structural composition of the charging box body. The charging box body includes an upper shell 1, a connecting shell 2, and a lower shell 3, which are detachably connected from top to bottom. The upper shell 1 and lower shell 3 are both circular, while the connecting shell 2 is annular. The top surface of the upper shell 1 has a groove 12, within which a solar photovoltaic panel 4 is installed. The connecting shell 2 contains multiple partitions 5, which divide the internal space of the connecting shell 2 into mutually perpendicular first mounting positions 6 and second mounting positions 7. The lower shell 3 contains a third mounting position 9 for installing a lithium battery.

[0036] The arrangement of the first mounting position 6 and the second mounting position 7 will be described next. For example... Figure 3 As shown, there is one first mounting position 6, which is located on the right side inside the connecting shell 2, and there are two second mounting positions 7, which are arranged at intervals and are both perpendicular to the left side of the first mounting position 6.

[0037] Next, the arrangement of the first circuit board 8 and the second circuit board 10 will be described. For example... Figure 3 As shown, the first circuit board 8 is located at the center inside the connecting housing 2 and between the two second mounting positions 7. The second circuit board 10 is located inside the lower housing 3 and corresponds vertically to the first circuit board 8. Both the first circuit board 8 and the second circuit board 10 are PCB control boards (i.e., printed circuit boards).

[0038] In addition, such as Figure 2 As shown, the bottom of the upper housing 1 also has a partition area 11 that matches the first mounting position 6, the second mounting position 7 and the first circuit board 8; the bottom center of the connecting housing 2 has an opening so that the first circuit board 8 and the second circuit board 10 can be connected; the first mounting position 6, the second mounting position 7 and the third mounting position 9 are all equipped with battery contact springs 13.

[0039] It should be noted that the solar charging box provided by this utility model can be installed on the top of an outdoor leisure umbrella such as a Roman umbrella. A nickel-metal hydride battery or a lithium battery is installed inside the solar charging box. The solar charging box powers the nickel-metal hydride battery or the lithium battery, and then powers the lighting installed on the Roman umbrella or other outdoor leisure umbrella.

[0040] The working principle of the solar charging box provided by this utility model is as follows:

[0041] When the nickel-metal hydride battery needs to be charged, the upper housing 1 and the connecting housing 2 are separated, and the nickel-metal hydride battery is installed in the first mounting position 6 or the second mounting position 7. Then the upper housing 1 and the connecting housing 2 are installed together. When sunlight shines on the solar photovoltaic panel 4 on the top surface of the upper housing 1, the solar photovoltaic panel 4 converts solar energy into electrical energy. This electrical energy is transmitted to the first circuit board 8 through the circuit to charge the nickel-metal hydride battery.

[0042] When the lithium battery needs to be charged, the lower housing 3 and the connecting housing 2 are separated, the lithium battery is installed in the third mounting position 9, and then the lower housing 3 and the connecting housing 2 are installed together. When sunlight shines on the solar photovoltaic panel 4 on the top surface of the upper housing 1, the solar photovoltaic panel 4 converts solar energy into electrical energy. This electrical energy is transmitted to the second circuit board 10 through the circuit to charge the lithium battery.

[0043] When it is necessary to charge both the nickel-metal hydride battery and the lithium battery simultaneously, the upper housing 1 and the connecting housing 2, and the lower housing 3 and the connecting housing 2 are disassembled in sequence. The nickel-metal hydride battery is installed in the first mounting position 6 or the second mounting position 7, and the lithium battery is installed in the third mounting position 9. Then, the upper housing 1, the connecting housing 2 and the lower housing 3 are assembled together in sequence. When sunlight shines on the solar photovoltaic panel 4 on the top surface of the upper housing 1, the solar photovoltaic panel 4 converts solar energy into electrical energy. This electrical energy is transmitted through the circuit to the first circuit board 8 and the second circuit board 10 to charge the nickel-metal hydride battery and the lithium battery.

[0044] Embodiment 2 of the solar charging box provided by this utility model:

[0045] Its main difference from Example 1 is:

[0046] In Example 1, both the upper and lower shells are circular.

[0047] In this embodiment, as Figure 5 As shown, both the upper and lower shells are rectangular with rounded corners.

[0048] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0049] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
