Description

Technical Field

[0001] This utility model relates to the field of high-voltage box technology, and in particular to a high-voltage box for a battery swapping system. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new onboard power devices), integrating advanced technologies in vehicle power control and drive systems to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles generally use electricity as their power source. Because electricity is a relatively clean energy source, new energy vehicles receive strong government support to enter millions of households.

[0003] New energy vehicles store electricity in batteries. To facilitate battery management, the battery swapping system of new energy vehicles includes a Battery Control Unit (BCU) for managing battery charging and discharging, thus extending battery life. Currently, the BCU and high-voltage box in new energy vehicles are separate structures. The high-voltage box is located on top of the battery, while the BCU is located at the bottom. The BCU includes a charging connector, a discharging connector, and a BCU control module. The BCU and the high-voltage box are connected by a connecting cable, with each end of the cable connecting to the high-voltage box, the charging connector, and the discharging connector, respectively. This results in cumbersome wiring during installation, reducing installation speed. Furthermore, the connecting cable is 3-4 meters long, leading to high manufacturing costs and increasing overall manufacturing costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a high-voltage box for a battery swapping system.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] Two charging connectors are provided and are fixedly mounted on the bottom surface of the box.

[0008] Two discharge connectors are provided and are fixedly mounted on the bottom surface of the housing.

[0009] The junction box is fixedly installed on the side of the housing and is connected to the battery via a power cord.

[0010] Preferably, the housing includes a main body and a top cover, the charging connector and the discharging connector are fixedly disposed on the bottom surface of the main body, the junction box is fixedly disposed on the side of the main body, and the top cover is fixedly connected to the main body.

[0011] Preferably, a BCU control module is provided inside the housing, and a copper busbar connects the BCU control module to the charging connector and the discharging connector.

[0012] Preferably, the wiring busbar is a braided copper busbar.

[0018] The beneficial effects of adopting the above technical solution are as follows:

[0019] 1. In this utility model, the charging connector is used to charge the battery and the discharging connector is used to discharge the battery, thereby enabling the car to drive and use. By setting the charging connector and the discharging connector on the high voltage box, the charging connector and the discharging connector are integrated together, which can reduce the use of connecting wires, eliminate the wiring process, and reduce the wiring steps during battery swapping, enabling quick replacement and reducing the amount of connecting wires used, thereby reducing manufacturing costs.

[0020] 2. In this utility model, the copper busbars connected to the charging connector and the discharging connector are made of braided copper busbars, which have a certain amount of deformation. When the car is bumpy during driving, the copper busbars are not easy to fall off or deform, which can prevent the car from malfunctioning. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1 and Figure 2As shown, a high-voltage box for a battery swapping system includes a box body 1, a charging connector 2, a discharging connector 3, and a junction box. In new energy vehicles, a mounting bracket is fixedly installed inside the vehicle body, and the battery is fixedly installed inside the mounting bracket. The box body 1 is fixedly installed at the bottom of the mounting bracket. The box body 1 has a cubic structure with six faces: a bottom face, a top face, and four side faces. Two charging connectors 2 and a discharging connector 3 are fixedly installed on the bottom face of the box body 1. The junction box 4 is located on one side of the box body 1 and is connected to the battery via a power cable 5. In a traditional high-voltage box installation structure, the box body 1 is fixedly installed at the top of the mounting bracket, and the charging connector and discharging connector of the battery main control unit are located at the bottom of the mounting bracket. The box body 1 is connected to the charging connector and the discharging connector via connecting cables. In this embodiment, the charging connector 2 and the discharging connector 3 are fixedly installed on the box body 1, and the box body 1 is located at the bottom of the mounting bracket, which allows the top of the mounting bracket to be connected. The space for the mounting box is increased by adding two sets of batteries, which expands the battery capacity. Simultaneously, the charging connector 2 and discharging connector 3 are fixedly mounted on the box 1, eliminating the need for connecting wires, reducing installation steps, and saving on manufacturing costs. Furthermore, both the charging connector 2 and discharging connector 3 are located on the bottom surface of the box 1. Due to the relatively narrow internal structure of the vehicle mounting bracket, having the charging connector 2 and discharging connector 3 on the same side makes it easier to quickly locate and connect external plugs. There are two charging connectors 2, used to connect to an external charging plug for charging the battery. Two charging connectors 2 increase the charging speed, and even if one is damaged, the other can still charge. There are also two discharging connectors 3, which connect to electrical equipment in the vehicle for use during vehicle operation and by the vehicle's electrical devices. The two discharging connectors 3 also ensure the safety of vehicle use.

[0029] Furthermore, the box 4 includes a main body 6 and a top cover 7. The charging connector 2 and the discharging connector 3 are fixedly disposed on the bottom surface of the main body 6. The charging connector 2 and the discharging connector 3 are connected to the main body 6 by screws. The junction box 4 is fixedly disposed on the side of the main body 6. The top cover 7 is fixedly connected to the main body 6.

[0030] Furthermore, such as Figure 3 As shown, a BCU control module 8 is provided inside the housing 1. A copper busbar 9 connects the BCU control module 8 to the charging connector 2 and the discharging connector 3. The BCU control module 8 is used to control the battery in the car so that the battery can be charged or discharged normally. For example, when an external plug is connected to the charging connector 2, the BCU control module 8 controls the charging of the battery and controls the discharging connector 3 not to supply power to the car's driving system.

[0031] Furthermore, the copper busbar 9 is a braided copper busbar, which has a certain deformation capacity, so it will not deform or break when the car vibrates or bumps during driving, and has stronger shock resistance than a rigid copper busbar.

[0032] Furthermore, the bottom surface of the main body 6 is provided with reinforcing ribs 10 to enhance the strength of the main body 6.

[0033] Furthermore, a fixing plate 11 is fixedly installed on the main body 6. The fixing plate 11 has mounting holes. After the bolts are inserted into the mounting holes, they are fixedly connected to the mounting bracket in the car, thus fixing the main body 6 onto the mounting bracket.

[0034] Furthermore, a sealing gasket is provided between the main body 6 and the upper cover 7 to prevent water from entering the box.

[0035] Furthermore, the box body 1 is manufactured using an injection molding process.

[0036] Furthermore, the charging connector 2 is provided with a first positioning post 12, and the discharging connector 3 is provided with a second positioning post 13, which facilitates the positioning of the external plug when it is inserted into the charging connector 2 and the discharging connector 3.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
