[0035] Reference below Figure 1-Figure 5 The electric drive assembly 1 according to the embodiment of the utility model is described

[0036] like Figure 1-Figure 5 As shown, the electric drive assembly 1 according to the utility model is used for a vehicle, and the electric drive assembly 1 includes an electric drive body 11 and a charging device 12. The electric drive body 11 is suitable for being electrically connected to a battery pack of a vehicle. A mounting surface 111 is formed on the side or top surface of the electric drive body 11, and a first connecting portion 112 is arranged on the mounting surface 111; a second connecting portion 1211 is arranged on the charging device 12, and the second connecting portion 1211 is cooperatively connected with the first connecting portion 112 to set the charging device 12 on the mounting surface 111.

[0037] According to the electric drive assembly 1 of the utility model, the electric drive body 11 is responsible for electrically connecting with the battery pack of the vehicle to obtain the electric energy required to drive the vehicle. A mounting surface 111 is formed on the side or top surface of the electric drive body 11, and the mounting surface 111 is used to install the charging device 12, so that the charging device 12 does not need to remove the parts of the electric drive body 11 when being installed or removed from the electric drive body 11, and the installation and disassembly are convenient, which improves the convenience and efficiency of maintenance. At the same time, since the charging device 12 is directly installed on the electric drive body 11, there is no need to reserve additional space or set up a mounting bracket in the cabin, which also reduces the manufacturing cost and space occupancy. By providing the charging device 12, the charging device 12 can charge the battery pack through the electric drive body 11.

[0038] Specifically, the mounting surface 111 is provided with a first connection portion 112, and the charging device 12 is provided with a second connection portion 1211 that matches the first connection portion 112. Through the cooperation between the first connection portion 112 and the second connection portion 1211, the charging device 12 can be accurately positioned and fixed on the mounting surface 111 of the electric drive body 11.

[0039] Therefore, according to the electric drive assembly 1 of the utility model, by installing the charging device 12 on the side or top surface of the electric drive body 11, the charging device 12 is conveniently installed and disassembled, the maintenance efficiency is improved, and the manufacturing cost and space occupation are reduced.

[0040] According to some embodiments of the present invention, Figure 1 As shown, a charging interface 111a is formed on the mounting surface 111, and the charging device 12 cooperates with the charging interface 111a to be electrically connected to the electric drive body 11. When the charging device 12 is mounted on the mounting surface 111, the charging device 12 can cooperate with the charging interface 111a to establish an electrical connection with the electric drive body 11, so that the charging device 12 can charge the battery pack through the electric drive body 11, thereby reducing unnecessary use of wiring harnesses and reducing costs.

[0041] According to some embodiments of the present invention, Figure 2-Figure 5 As shown, the electric drive assembly 1 also includes an electric control device 13, which is disposed on the side or top surface of the electric drive body 11 and is electrically connected to the electric drive body 11. By providing the electric control device 13, the electric control device 13 is used to control the operating state of the electric drive body 11, such as forward rotation, reverse rotation, etc. of the motor. Communication and control are achieved between the electric control device 13 and the electric drive body 11 through electrical connection, so that the electric control device 13 can accurately and quickly receive and send instructions to achieve precise control of the electric drive body 11. The electric control device 13 is disposed on the side or top surface of the electric drive body 11. Specifically, the electric control device 13 can be disposed on the same side, adjacent side, or opposite side of the charging device 12. The size of the electric drive assembly 1 can be optimized according to different arrangements, for example, by reducing the size of the electric drive assembly 1. Figure 2 The X-direction dimension of the electric drive assembly 1 shown, or reduced as Figure 3 The Z-direction dimension of the electric drive assembly 1 is shown; the function of the electric drive assembly 1 can also be optimized according to different arrangements, for example Figure 4 In the electric drive assembly 1 shown, the electric control device 13 and the charging device 12 are respectively arranged on different sides of the electric drive body 11, so that the electric control device 13 and the charging device 12 can better perform their respective functions.

[0042] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, the electric control device 13 and the charging device 12 are arranged side by side on the mounting surface 111. On the mounting surface 111, the electric control device 13 and the charging device 12 are placed side by side and adjacent to each other, which helps to optimize the use of space, making the electric control device 13 and the charging device 12 easier to access and maintain, while maintaining the independence and functionality of the electric control device 13 and the charging device 12.

[0043] According to some embodiments of the present invention, Figure 1As shown, a first cooling channel is provided in the electric drive body 11, a cooling interface 111b connected to the first cooling channel is formed on the mounting surface 111, and a second cooling channel is provided in the charging device 12, and the charging device 12 cooperates with the cooling interface 111b to connect the first cooling channel with the second cooling channel. By setting the first cooling channel in the electric drive body 11, the first cooling channel is used to circulate the coolant to take away the heat generated by the electric drive body 11 during operation, so as to ensure that the electric drive body 11 can operate continuously and stably. A cooling interface 111b is formed on the mounting surface 111, so that the first cooling channel can be connected to the second cooling channel in the charging device 12. Through the cooling interface 111b, the coolant can circulate between the first cooling channel and the second cooling channel, improve the integration, and help optimize the cooling efficiency. Specifically, when the electric drive system and the charging device 12 are working at the same time, the coolant can flow out of the electric drive body 11 through the first cooling channel, enter the second cooling channel through the cooling interface 111b, and thus cool the charging device 12. Similarly, the coolant may also flow out from the second cooling channel of the charging device 12 and enter the first cooling channel of the electric drive body 11 through the cooling interface 111b, thereby forming a cooling cycle.

[0044] According to some embodiments of the present invention, Figure 1 As shown, the charging device 12 includes a device body 121 and a cooling pipe 122, the second connecting portion 1211 is arranged on the device body 121, at least part of the cooling pipe 122 is arranged in the device body 121 and is formed with a second cooling channel, and at least another part of the cooling pipe 122 extends out of the device body 121 and cooperates with the cooling interface 111b. The device body 121 is used to provide electrical energy to the battery pack. The cooling pipe 122 is a component of the charging device 12 for cooling. A second cooling channel is formed inside the cooling pipe 122, and the second cooling channel is used to circulate coolant to take away the heat generated during the charging and discharging process. At least part of the cooling pipe 122 is arranged in the device body 121, so that the coolant can be effectively circulated in the device body 121. At least another part of the cooling pipe 122 extends from the device body 121 to facilitate cooperation and connection with the cooling interface 111b, so that the first cooling channel and the second cooling channel can be connected to form a cooling cycle.

[0045] According to some embodiments of the present invention, Figure 1As shown, one of the first connection part 112 and the second connection part 1211 is formed with a plug hole, and the other of the first connection part 112 and the second connection part 1211 is configured as a plug connector that plugs into the plug hole. The first connection part 112 and the second connection part 1211 are connected by plugging and matching the plug connector with the plug hole, so that the first connection part 112 and the second connection part 1211 can be quickly connected or disassembled, which simplifies the installation and disassembly process and improves work efficiency. The plug hole and the plug connector have matching sizes and shapes. When the plug connector is inserted into the plug hole, the relative position between the first connection part 112 and the second connection part 1211 can be accurate, which is conducive to the installation and positioning of the charging device 12. The matching between the plug hole and the plug connector can provide sufficient connection strength, so that the first connection part 112 and the second connection part 1211 are not easy to separate.

[0046] According to some embodiments of the present invention, Figure 1 As shown, the second connection portion 1211 is configured as a plurality of spaced apart portions along the edge of the charging device 12, and the first connection portion 112 is configured as a plurality of spaced apart portions corresponding to the second connection portion 1211. By arranging a plurality of spaced apart second connection portions 1211 on the edge of the charging device 12, and correspondingly arranging a plurality of first connection portions 112 on the mounting surface 111, a multi-point connection between the charging device 12 and the electric drive body 11 can be achieved, which helps to improve the stability and firmness of the connection, and can also provide a more uniform force distribution and improve the reliability of the connection.

[0047] According to some embodiments of the utility model, the charging device 12 and the mounting surface 111 are clearance-matched to define a heat dissipation channel suitable for gas circulation between each other. Clearance-matching means that some space is reserved between the charging device 12 and the mounting surface 111 during assembly, rather than being tightly fitted. The gap between the charging device 12 and the mounting surface 111 forms a heat dissipation channel, which allows gas to circulate therein, and can effectively take away the heat generated by the charging device 12, thereby playing a role in heat dissipation.

[0048] According to some embodiments of the utility model, the electric drive assembly 1 also includes a reducer, which is connected to the output shaft of the electric drive body 11. The reducer is a transmission device that can reduce the rotation speed and increase the torque. The reducer can be used to reduce the rotation speed of the output shaft and increase the torque output. Through the connection between the reducer and the output shaft, the electric drive assembly 1 can more effectively utilize the power of the motor to meet the different needs of the vehicle when driving. For example, when the vehicle starts or climbs a slope, the reducer can play an important role and provide a greater torque output. In addition, the reducer can also protect the motor. Since the reducer can reduce the rotation speed, it can reduce the wear and heat of the motor at high speeds and extend the service life of the motor.
