Specific Embodiments

[0021] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] As Figures 1 to 6 shown, the on-vehicle AC and DC power supply system described in this embodiment aims to provide a compact and powerful power control box, which is applicable to various outdoor, on-vehicle and other scenarios that require stable power supply.

[0023] The box body 100 is the external structure of the system, which is used to accommodate the battery pack 200 and other electronic components and provide protection. It is composed of the main body 10, two side plates 20, a suspension plate 30 and at least two bottom plates 40.

[0024] Among them, a plurality of interfaces for power input or output are provided on the box body 100. The interfaces include an Anderson socket 101, an AC socket 102, a cigarette lighter 103, and a solar charger 104. The box body 100 includes a main body 10, two side plates 20, a suspension plate 30, and at least two bottom plates 40. The main body 10 is a U-shaped structure formed by bending the two long sides of a rectangular aluminum alloy plate towards each other. After the main body 10 is folded, the two long sides are bent inward to form a horizontally extending support portion 11, and the battery pack 200 is located inside the main body 10. The suspension plate 30 is fixedly installed on the two support portions 11 through fasteners, and lugs are provided at the edges of the suspension plate 30. The two side plates 20 are installed at both ends in the length direction of the main body 10 through fasteners. A plurality of maintenance openings 12 for maintaining internal components are formed at the bottom of the main body 10 along the length direction of the main body 10 itself, and a bottom plate 40 is detachably installed at the opening position of each maintenance opening 12. A recessed portion 13 is formed by inwards concaving the bottom edge portion of the main body 10, and the Anderson socket 101 is fixedly installed in the recessed portion 13. The AC socket 102 is fixedly installed on one or more bottom plates 40, and the USB interface 103, the cigarette lighter 103, and the solar charger 104 are fixedly installed on the two side plates 20. In this embodiment, in some embodiments, the fasteners are screws or rivets.

[0025] Specifically, the main body 10 is designed in a U-shaped structure and is formed by bending the two long sides of a rectangular aluminum alloy plate towards each other. This design increases the strength and rigidity of the box body, enabling it to withstand certain external impacts and vibrations. After the main body 10 is folded, the two long sides are bent inward to form a horizontally extending support portion 11 for supporting the suspension plate 30 and the battery pack 200. The battery pack 200 is located inside the main body 10 and is effectively protected. In this embodiment, the main body 10 preferably adopts a 5052 aluminum sandblasting process, which is light and has high strength, high strength and lightweight, and can operate stably and for a long time in a hanging and vibrating working environment.

[0026] The suspension plate 30 is fixedly installed on the two support portions 11 through fasteners. Lugs (not shown in the figure) are provided at the edges of the suspension plate 30, which facilitates the user to hang the system in various positions. This hanging design is particularly suitable for outdoor and vehicle-mounted environments, which can save space and improve the portability of the system.

[0027] The two side plates 20 are installed at both ends in the length direction of the main body 10 through fasteners, and together with the main body 10 and the bottom plate 40, they form a closed box body structure, effectively preventing dust, water vapor, etc. from entering the inside of the box body and protecting the electronic components from environmental factors.

[0028] To facilitate users in inspecting and maintaining the internal components of the system, a plurality of inspection openings 12 are provided along the length direction of the bottom of the main body 10. A bottom plate 40 is detachably installed at the opening position of each inspection opening 12. Users can remove the corresponding bottom plate 40 as needed to conveniently access and maintain the electronic components inside the system.

[0029] To better accommodate and protect the Anderson socket 101, a recessed portion 13 is formed by the inward concavity of the bottom edge portion of the main body 10. The Anderson socket 101 is fixedly installed within the recessed portion 13. This design can prevent the Anderson socket 101 from being accidentally collided or damaged during use and improves the overall aesthetics of the system.

[0030] To facilitate users in using various electronic devices, the system provides multiple types of power output interfaces, including the Anderson socket 101, AC socket 102, cigarette lighter 103, and solar charger 104. The AC socket 102 is fixedly installed on one or more bottom plates 40, and the cigarette lighter 103 and solar charger 104 are fixedly installed on the two side plates 20, facilitating users to connect various devices.

[0031] In some embodiments, as Figure 2 、 Figure 5 shown, it further includes a sheet metal support member 80. The sheet metal support member 80 has a first folded edge 81 and a second folded edge 82 that are bent towards each other. The first folded edge 81 extends vertically and is fixedly connected to the two long sides of the main body 10, and the second folded edge 82 extends horizontally and is fixedly connected to the bottom surface of the support portion 11.

[0032] Specifically in implementation, the sheet metal support member 80 is made of a metal material such as cold-rolled steel plate or galvanized steel plate and is formed by stamping. Its first folded edge 81 extends vertically and is fixedly connected to the two long sides of the main body 10 by means such as welding, riveting, or screwing, and the second folded edge 82 extends horizontally and is fixedly connected to the bottom surface of the support portion 11 by means such as welding, riveting, or screwing.

[0033] In this way, the sheet metal support member 80 is equivalent to adding a connecting member between the main body 10 and the support portion 11, forming a more stable triangular structure, effectively improving the overall bending and torsional resistance of the box body. Especially for the on-vehicle suspended use scenario, the sheet metal support member 80 can effectively prevent the box body from deforming under the action of gravity and ensure the stable operation of the system.

[0034] In some embodiments, as Figure 2 、 Figure 4 、 Figure 5As shown, a number of relatively arranged heat dissipation grids 90 are provided on the two long sides of the main body 10, and at least one heat dissipation fan 91 is fixedly installed in the main body 10. The heat dissipation fan 91 is fixedly installed at the position where any one of the heat dissipation grids 90 is located.

[0035] In specific implementation, these heat dissipation grids 90 can adopt openings in, for example, strip shape, circular shape or other shapes to facilitate air circulation. The heat dissipation fan 91 fixedly installed in the main body 10 can select a suitable size and power according to actual needs and is installed at the position where any one of the heat dissipation grids 90 is located through, for example, screw fixation and other means, so that the air flow direction of the fan is consistent with the direction of the heat dissipation grid 90 to maximize the heat dissipation efficiency. If the power control system needs to work in a high-temperature environment, such as in a hot summer or a closed carriage, the temperature inside the system is likely to rise. Then the heat dissipation fan 91 can actively dissipate heat to discharge the heat outside the box body to ensure the stable operation of the system in a high-temperature environment.

[0036] In some embodiments, as Figure 5 shown, two U-shaped support plates 14 are formed by bending the two short sides of the main body 10. The U-shaped support plates 14 have fixing ears (not shown in the figure) fixedly connected to the main body 10, and the side plates 20 are fixedly connected to the U-shaped support plates 14 through fasteners.

[0037] With this structural design, the integrated design of the U-shaped support plates 14 and the fixing ears reduces the number of parts, simplifies the assembly process of the box body, reduces the production cost, and the side plates 20 are directly fixed on the U-shaped support plates 14, avoiding complex connection structures and making the assembly more convenient and fast. In addition, the U-shaped support plates 14 increase the overall rigidity of the box body structure, improve the anti-bending and anti-torsion capabilities of the box body, enabling it to better withstand external impacts and vibrations.

[0038] In some embodiments, as Figure 6 shown, a fuse support 50 is provided in any one of the inspection openings 12. The fuse support 50 is located inside the main body 10 and is used for installing a fuse module 51 for overload protection.

[0039] In specific implementation, a fuse support 50 is provided in any one of the inspection openings 12. The fuse support 50 can be made of an insulating material such as plastic or metal and is fixed inside the main body 10 through, for example, screw fixation and other means, at a position close to the inspection opening 12. The fuse support 50 is provided with a slot or socket for installing the fuse module 51. The fuse module 51 can select a suitable specification and type according to actual needs and is inserted or clamped on the fuse support 50, facilitating users to quickly access and replace it. Without disassembling the entire box body 100, the maintenance and replacement of the fuse can be carried out, saving time and effort.

[0040] In some embodiments, asFigure 3 , Figure 6 As shown in Figure 6 , a coulomb meter 21 for displaying the power of the battery pack 200 is further installed on the side plate 20. The coulomb meter 21 can adopt display methods such as an LCD liquid crystal display screen or an LED digital tube, and is fixed at an appropriate position on the side plate 20 by means such as screw fixation or snap connection, which is convenient for users to observe. In one embodiment, the coulomb meter 21 is connected to the battery management system (BMS), and can obtain the power information of the battery pack 200 in real time and display it.

[0041] In some embodiments, as Figure 2 shown, the battery pack 200 is integrated in the protective shell 60. A plurality of support ribs 61 are fixedly installed on the top of the protective shell 60, and the support ribs 61 are detachably installed on the suspension plate 30.

[0042] Specifically, the protective shell 60 can be made of impact-resistant materials such as metal or engineering plastics, and is designed according to the size and shape of the battery pack 200. A plurality of support ribs 61 are fixedly installed on the top of the protective shell 60. The support ribs 61 can be made of materials such as metal or plastic, and are detachably installed on the suspension plate 30 by means such as screw connection or snap connection.

[0043] In this embodiment, the battery pack 200 is designed as an independent module, which significantly simplifies the maintenance process. When internal components need to be maintained, the user can first remove the fasteners and take down the main body 10 together with the side plate 20 and the bottom plate 40 thereon. Since the battery pack 200 is fixed on the suspension plate 30 by the support ribs 61, the battery pack 200 is still fixed on the suspension plate at this time, and the user can directly perform maintenance operations on the exposed battery pack 200, such as checking the circuit connection or replacing the cooling fan 91, etc. If more in-depth maintenance or replacement of the battery pack 200 is required, the support ribs 61 can be further removed to take down the entire battery pack 200 and its protective shell 60 from the suspension plate 30. This modular design makes the maintenance process more flexible and convenient, without having to disassemble the entire system, thus saving time and effort.

[0044] In some embodiments, as Figure 2 shown, a plurality of L-shaped reinforcing ribs 70 are installed in the main body 10 through fasteners, and the L-shaped reinforcing ribs 70 extend along the length direction of the main body 10. In this embodiment, the L-shaped reinforcing ribs 70 can be made by bending metal plates or extruding profiles, etc., and extend along the length direction of the main body 10. It increases the thickness and bending resistance of the main body 10, enabling it to better resist external pressure and impact, especially the force in the length direction.

[0045] The on-vehicle AC and DC power supply system provided by this embodiment integrates a battery pack and multiple power interfaces, achieving the goals of saving space, simplifying installation, and improving reliability and safety. Its detachable bottom plate and maintenance port design facilitate maintenance, while its suspended installation method and rib design enable it to adapt to special environments such as bumps and vibrations in the carriage. The multiple power interfaces meet the power consumption needs of different devices, enhancing the user experience.
