[0036] With the continuous development and iteration of new energy vehicles, while their functions are constantly improving, they need to integrate a large number of control components within the vehicle, such as battery management systems, vehicle control units, motor control units, circuit breakers, power distribution units, power conversion modules, on-board charging units, and body stability systems to meet the operation of the entire vehicle or its different mechanisms. Among them, different control components have different requirements for the installation environment. For example, some precision electrical components need to meet the protection level of IP68 for waterproof and dustproof, while some high-voltage electrical components require an electromagnetic shielding environment to improve their safety.

[0037] Among related products, electronic control boxes are integrally formed using a die-casting process to meet the stringent cleanliness, liquid cooling, and lightweight requirements of some control components. However, die-casting processes are associated with high mold costs and long development cycles, hindering production cost control and making it difficult to meet the demand for continuous product updates. Furthermore, once the mold is opened, die-cast electronic control boxes are difficult to modify, resulting in limited versatility.

[0038] In order to solve the problems of the prior art, the embodiments of the present application provide an all-in-one electric control box and a new energy vehicle, wherein the all-in-one of the all-in-one electric control box means that the electric control box can integrate and install at least two of the battery management system (BMS), vehicle control unit (VCU), motor control unit (MCU), battery disconnect unit (BDU), power distribution unit (PDU), power conversion module (DC / DC), on-board charger (OBC), and electronic stability program (ESP). The all-in-one electric control box provided in the embodiments of the present application is first introduced below.

[0039] See also Figures 1 to 2The embodiment of the present application provides an all-in-one electric control box, which includes a first housing 100, a second housing 200, and a first sealing member 310.

The second housing 200 includes a first reference surface 201 and a box body 202 that are fixedly connected. The box body 202 is fixedly connected to the body of the new energy vehicle. The first reference surface 201 is arranged toward the first housing 100 and is detachably connected to the first housing 100. The first sealing member 310 is sandwiched between the first housing 100 and the second housing 200 along the first direction and is arranged along the circumference of the first reference surface 201. The first reference surface 201 defines a plug-in slot 2011. When the first housing 100 and the second housing 200 are assembled, the second mounting position 102 can enter the box body 202 through the plug-in slot 2011.

[0040] The second housing 200's box body 202 covers the electrical components mounted in the second mounting location 102, protecting them and providing graded protection for the various components. A first seal 310 is also provided at the junction between the first and second housings 100 and 200. The orthographic projection of the first seal 310 on the first reference plane 201 forms a continuous, closed shape, reducing the possibility of moisture or dust intruding into the second mounting location 102 from all directions.

[0041] As a result, the separately configured first housing 100 and second housing 200 can be manufactured using different processes, reducing production costs and shortening development cycles for the all-in-one electrical control box. The second housing 200 can be designed specifically for the electrical components installed in the second mounting position 102, enhancing the versatility of the all-in-one electrical control box. Furthermore, during subsequent maintenance, the first housing housing housing the electrical components can be disassembled separately for inspection, improving the maintainability and efficiency of the all-in-one electrical control box.

[0060] Optionally, along the first direction, the orthographic projection of the first side wall 2021 on the first reference plane 201 falls within the range of the first reference plane 201, thereby achieving waterproof protection for the electrical components at the second installation position 102 while reducing the volume of the box body 202 in the multi-in-one electrical control box, reducing the overall volume of the multi-in-one electrical control box, and improving the integration.

[0061] Optionally, at least one of the bottom wall, the first side wall 2021 , the second side wall 2022 , and the first reference surface 201 is a profile having a cavity.

[0062] Thus, the first side wall 2021 is sealed and connected to the first reference surface 201 through the second side wall 2022, and together with the bottom wall of the upper cover 210 forms a cavity to accommodate the second installation position 102 and electrical components, achieving waterproof and sealed protection.

[0063] According to certain embodiments of the present application, at least one of the bottom wall, the first side wall 2021 and the second side wall 2022 is provided with a mounting structure 230 .

[0064] Optionally, see Figure 3 , the mounting structure 230 is set on the bottom wall.

[0065] Optionally, the mounting structure 230 is configured as a welding nut.

[0066] Optionally, the mounting structure 230 is configured as a rivet nut.

[0067] Thus, the second housing 200 is fixedly installed in the body of the new energy vehicle through the mounting structure 230 to achieve the installation of the all-in-one electric control box.

[0068] According to certain embodiments of the present application, a limiting structure 240 is provided in the box body 202 , the limiting structure 240 defines a limiting hole 2411 , and the first shell 100 is provided with a limiting portion 110 capable of cooperating with the limiting hole 2411 .

[0070] Optionally, the limiting structure 240 is detachably connected to the box body 202 to facilitate replacement of the limiting structure 240 .

[0071] Therefore, the limiting hole 2411 accommodates the limiting portion 110, reducing the jumping of the limiting portion 110 relative to the limiting structure 240, improving the positioning accuracy and the stability of the connection between the first shell 100 and the second shell 200.

[0072] See also Figure 6 According to certain embodiments of the present application, the limiting structure 240 includes a limiting body 241 , a limiting hole 2411 is opened in the limiting body 241 , and the limiting body 241 is made of a deformable elastic material.

[0073] Optionally, the limiting body 241 is made of rubber.

[0074] Please continue reading Figure 6 Optionally, the limiting structure 240 also includes a first lip 2421 formed by extending from the end of the limiting body 241 close to the first reference plane 201, and a second lip 2422 formed by extending from the end of the limiting body 241 away from the first reference plane 201, and a slot is formed between the first lip 2421 and the second lip 2422 to accommodate the first side wall 2021.

[0077] Thus, the limiting body 241 can deform to improve the sealing between the limiting structure 240 and the box body 202, further improving the waterproof and dustproof performance of the second housing 200. In addition, the elastically deformable limiting body 241 can increase the assembly tolerance between the limiting portion 110 and the limiting structure 240, making the assembly between the first housing 100 and the second housing 200 more successful.
