[0002] New energy generally refers to renewable energy developed and utilized based on new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy, and tidal energy, as well as the thermal cycle between the ocean surface and deep layers. In addition, there are hydrogen energy, biogas, alcohol, methanol, etc. Energy sources that have been widely used, such as coal, oil, natural gas, and hydropower, are called conventional energy. With the finite nature of conventional energy and the increasing prominence of environmental problems, new energy sources, characterized by environmental protection and renewability, are receiving more and more attention from countries around the world.
[0003] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new on-board power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. Electric vehicle batteries are divided into two main categories: storage batteries and fuel cells. Storage batteries are suitable for pure electric vehicles and include lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries. Fuel cells are specifically used in fuel cell electric vehicles, including alkaline fuel cells (AFC).
[0004] The power supply boxes for new energy vehicles have the following drawbacks: most power supply boxes are "integrated" structures, with internal components such as battery packs, cooling modules, and sensors tightly integrated. During maintenance, the entire box needs to be disassembled, which is time-consuming and can easily damage surrounding components. Therefore, a new type of power supply box for new energy vehicles is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a power supply box for new energy vehicles, which aims to improve the problem that most power supply boxes in the prior art are "integrated" structures, requiring complete disassembly during maintenance, which is time-consuming and easily damages surrounding components.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a power supply box for a new energy vehicle, comprising a chassis frame and mounting holes for fasteners. The mounting holes for fasteners are formed on the top inner wall of the chassis frame. A power module is snapped onto the bottom outer wall of the chassis frame. An adjustment mechanism and an auxiliary mechanism are provided on the chassis frame. The adjustment mechanism includes an annular opening formed on the left inner wall of the chassis frame. A positioning opening is formed on the bottom inner wall of the chassis frame. A fixing screw is threaded onto the right inner wall of the annular opening. A positioning plate is snapped onto the bottom inner wall of the positioning opening. A power supply box housing is fixedly connected to the left outer wall of the positioning plate. A cooling module is fixedly connected to the bottom inner wall of the power supply box housing.
[0007] As a further description of the above technical solution: the auxiliary mechanism includes a square groove, which is formed on the bottom outer wall of the power module. A fixing frame is fixedly connected to the bottom outer wall of the chassis frame. An adjusting plate is slidably connected to the front inner wall of the fixing frame. An insert plate is fixedly connected to the bottom outer wall of the adjusting plate. An anti-fall plate is slidably connected to the bottom inner wall of the square groove. A compression spring is fixedly connected to the top outer wall of the adjusting plate.
[0008] As a further description of the above technical solution: the annular opening penetrates the left outer wall of the chassis frame, and there are two positioning plates, which are respectively fixedly connected to the left and right outer walls of the power supply box housing.
[0009] As a further description of the above technical solution: the sensor module body is fixedly connected to the bottom inner wall of the power supply box housing, and the fixing screw passes through the right inner wall of the positioning plate.
[0010] As a further description of the above technical solution: a wear-resistant sleeve is fixedly connected to the inner wall of the inner ring of the positioning plate, and a silicone particle plate is fixedly connected to the top inner wall of the power supply box housing.
[0011] As a further description of the above technical solution: the insert plate penetrates the top inner wall of the anti-fall plate, the anti-fall plate is slidably connected to the front inner wall of the fixed frame, and the end of the compression spring away from the adjusting plate is fixedly connected to the top inner wall of the fixed frame.
[0012] As a further description of the above technical solution: silicone pads are fixedly connected to the outer walls of the top and bottom sides of the adjustment plate, and the insert plate penetrates the top inner wall of the anti-fall plate.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the power supply box housing and chassis frame can be easily separated by the adjustment mechanism, so that the cooling module, sensor module body and power supply module form a modular structure that can be disassembled and installed separately without overall disassembly, greatly reducing maintenance time. At the same time, the double-sided positioning plates and fixing screws work together to ensure that the power supply box housing is installed firmly and avoids displacement. In addition, the silicone particle plate can absorb moisture in the air, reducing the risk of moisture entering the power supply module.
[0015] 2. In this utility model, the compression spring in the auxiliary mechanism, together with the insertion plate and the anti-fall plate, can effectively prevent the power module from falling off accidentally. The silicone pad enhances the friction during operation, improves the safety and structural reliability, and can quickly release the fixation of a single power module, making it convenient to replace the faulty module in a targeted manner, avoiding the high cost of replacing the whole module, and significantly improving the convenience and economy of maintenance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-3This utility model provides an embodiment of a new energy vehicle power supply box, including a chassis frame 1 and mounting holes 2 for fasteners. The mounting holes 2 are formed on the top inner wall of the chassis frame 1. The chassis frame 1 serves as the basic support structure for the entire power supply box, providing a mounting carrier for various components. The mounting holes 2 facilitate the installation of the chassis frame 1 at designated positions on the new energy vehicle using bolts or other fasteners, ensuring the overall stability of the power supply box. A power module 3 is snapped onto the bottom outer wall of the chassis frame 1. An adjustment mechanism 4 and an auxiliary mechanism 5 are provided on the chassis frame 1. The adjustment mechanism 4 includes an annular opening 41. The opening 41 is located on the left inner wall of the chassis frame 1. The bottom inner wall of the chassis frame 1 is provided with a positioning opening 42. The positioning opening 42 is used to accommodate the positioning plate 44, which plays a positioning and guiding role to ensure accurate installation. The right inner wall of the ring opening 41 is threaded with a fixing screw 43. The bottom inner wall of the positioning opening 42 is snapped with the positioning plate 44. The left outer wall of the positioning plate 44 is fixedly connected with the power box housing 45. The power box housing 45 serves as an outer shell to protect the internal cooling module 46, sensor module body 47 and other components, and to isolate external impurities. The bottom inner wall of the power box housing 45 is fixedly connected with the cooling module 46.
[0024] Reference Figures 2-4 The ring 41 penetrates the left outer wall of the chassis frame 1. There are two positioning plates 44, which are fixedly connected to the left and right outer walls of the power supply box housing 45 respectively. The double positioning plates 44 make the power supply box housing 45 bear force evenly, avoid installation misalignment, and enhance connection stability. The sensor module body 47 is fixedly connected to the bottom inner wall of the power supply box housing 45. The fixing screw 43 penetrates the right inner wall of the positioning plate 44. The inner ring inner wall of the positioning plate 44 is fixedly connected to a wear-resistant sleeve. The wear-resistant sleeve can reduce the friction wear between the fixing screw 43 and the positioning plate 44 and extend the service life of the components. The top inner wall of the power supply box housing 45 is fixedly connected to a silicone particle plate. By setting the silicone particle plate, a certain amount of moisture in the surrounding air is absorbed and released, reducing the amount of residual moisture in the air entering the power supply module 3 and causing potential hazards.
[0025] Reference Figures 3-4The auxiliary mechanism 5 includes a square groove 51, which is formed on the bottom outer wall of the power module 3. A fixed frame 52 is fixedly connected to the bottom outer wall of the chassis frame 1. An adjusting plate 53 is slidably connected to the front inner wall of the fixed frame 52. An insert plate 54 is fixedly connected to the bottom outer wall of the adjusting plate 53. The insert plate 54 locks or unlocks the anti-fall plate 56 by inserting or disengaging from it. The anti-fall plate 56 is slidably connected to the bottom inner wall of the square groove 51. A compression spring 55 is fixedly connected to the top outer wall of the adjusting plate 53. The insert plate 54 penetrates the top inner wall of the anti-fall plate 56. The anti-fall plate 56 is slidably connected to the front inner wall of the fixed frame 52. The end of the compression spring 55 away from the adjusting plate 53 is fixedly connected to the top inner wall of the fixed frame 52. Silicone pads are fixedly connected to the top and bottom outer walls of the adjusting plate 53. The silicone pads can increase the friction of the hand and prevent the operator from slipping. The insert plate 54 penetrates the top inner wall of the anti-fall plate 56.
[0026] Working principle: When maintenance is required, the single fixing screw 43 is pulled out from the ring 41 by rotating it, and at the same time, the fixing screw 43 is pulled out from the inner wall of the positioning plate 44. Then, the positioning plate 44 is pulled out from the lower part of the positioning port 42, so that the power box housing 45 can be easily opened to allow the cooling module 46 to be attached away from the power module 3. This allows the cooling module 46 and the power module 3 to be easily separated in a modular manner. At the same time, the modular sensor module body 47 is installed inside the power box housing 45 and is installed separately from the cooling module 46 and the power module 3. This makes it easier for personnel to mechanically disassemble and maintain which modular components are equipped with mechanical functions, reducing the overall disassembly and assembly time. If a single small module of the power module 3 fails, the insertion plate 54 is moved upward by pulling the adjustment plate 53. The insertion plate 54 moves upward and separates from the anti-fall plate 56. Then, the anti-fall plate 56 is moved forward from the square groove 51. Then, the single power module 3 is pulled out from the side for maintenance and replacement of the single power module 3, reducing the cost of overall replacement and improving the maintenance efficiency of the power module 3.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
