[0023] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0024] Reference below Figure 1The electric drive upper assembly 1 according to an embodiment of the utility model is described.

[0025] like Figure 1 As shown, the electric drive upper assembly 1 according to the embodiment of the utility model comprises: an engine 10 and an electric drive upper assembly 20. The engine 10 is a component of the electric drive upper assembly 1, and can mainly provide power, speed control and dynamic balance, perform energy conversion and auxiliary system driving, and the electric drive upper assembly 20 can mainly provide power and drive the vehicle forward, backward and turn.

[0026] like Figure 1 As shown, the electric drive upper assembly 20 includes: a generator 200, which is driven and matched with the engine 10. The generator 200 is a component of the drive upper assembly 20, which can mainly convert other forms of energy into electrical energy to provide power for various electrical equipment. The generator 200 is driven and matched with the engine 10, so there is no need to set up the engine 10 power take-off, transmission shaft and bracket, generator 200 bracket and other components, thereby reducing the mechanical transmission device, reducing the overall weight of the electric drive upper assembly 1, and reducing the cost. In addition, the mechanical transmission part between the engine 10 and the generator 200 is reduced, so that the electric drive upper assembly 1 can be optimized and the transmission and assembly efficiency of the electric drive upper assembly 1 can be improved.

[0027] Thus, the generator 200 is integrated into the engine 10, and the generator 200 is driven in cooperation with the engine 10, so that there is no need to set up components such as the engine 10 power take-off, the transmission shaft and the bracket, and the generator 200 bracket, thereby reducing the mechanical transmission device, reducing the overall weight of the electric drive upper assembly 1, and reducing the cost. In addition, the mechanical transmission part between the engine 10 and the generator 200 is reduced, which can optimize the electric drive upper assembly 1 and improve the transmission and assembly efficiency of the electric drive upper assembly 1.

[0028] Specifically, Figure 1 As shown, the engine 10 includes a drive train 100, which is driven and matched with the engine 10. The drive train 100 can mainly provide driving force for the vehicle to travel, and the drive train 100 and the engine 10 can drive and match, so as to improve the performance, efficiency and controllability of the vehicle. In addition, the drive train 100 can provide driving force for the generator 200.

[0029] Among them, Figure 1As shown, the engine 10 further includes: a flywheel housing 101, a drive train 100 is arranged in the flywheel housing 101, and a generator 200 is arranged on the flywheel housing 101. The flywheel housing 101 can mainly provide structural support, protect key components, reduce vibration and noise, and help stabilize the operation of the engine 10. The drive train 100 is arranged in the flywheel housing 101. At this time, the flywheel housing 101 can protect the drive train 100, thereby avoiding the wear and failure of the drive train. The generator 200 is arranged on the flywheel housing 101, that is, the generator 200 is integrated on the flywheel housing 101 of the engine 10. At this time, the generator 200 can be driven and matched with the engine 10, the mechanical transmission device can be reduced, the overall weight of the electric drive upper assembly 1 can be reduced, and the cost can be reduced. In addition, the mechanical transmission part between the engine 10 and the generator 200 can be reduced, the electric drive upper assembly 1 can be optimized, and the transmission and assembly efficiency of the electric drive upper assembly 1 can be improved.

[0030] In addition, if Figure 1 As shown, the electric drive upper assembly 20 also includes: a battery 201, and the generator 200 is electrically connected to the battery 201. The battery 201 is a device that can convert chemical energy into electrical energy, and is widely used in electronic equipment to provide necessary power support for the equipment. The generator 200 is electrically connected to the battery 201, so that the generator 200 can charge the battery 201. Under braking conditions, when the engine 10 is idling, the generator 200 can recover energy and charge the battery 201. At this time, the generator 200 can recover energy through the braking of the whole vehicle, reducing energy loss, which can indirectly improve the power generation efficiency and reduce the fuel consumption of the whole vehicle.

[0031] Of course, if Figure 1 As shown, the electric drive upper assembly 1 also includes: a controller 30, and the generator 200 and the battery 201 are electrically connected to the controller 30 respectively. The controller 30 can mainly change the main circuit or the control circuit according to the predetermined method, and the generator 200 and the battery 201 are electrically connected to the controller 30 respectively. The controller 30 can realize the starting, speed regulation, braking and reverse control of the generator 200, as well as the power measurement, display and protection of the power generation process. The controller 30 can ensure the safe and reliable use of the battery 201, can control the charging and discharging of the battery 200, and can report the basic parameters and fault information of the battery 200.

[0032] Furthermore, if Figure 1As shown, the controller 30 is an electronic controller or a vehicle electronic control unit. The electronic controller can mainly receive and process sensor information, and control the actuator through the output interface to achieve the predetermined function. The vehicle electronic control unit can mainly receive and process input signals from sensors or other devices, provide all data required by the vehicle, and issue work commands to various actuators after analysis and processing to achieve various functions and controls of the vehicle. Since the generator 200 is integrated into the engine 10, the generator 200 controller 30 can be integrated into the electronic controller or the vehicle electronic control unit. The electronic controller or the vehicle electronic control unit can control the controller 30 to generate electricity with the required power according to the vehicle speed, the engine 10 speed, the battery charge state, etc. The generator 200 controller 30 is integrated into the electronic controller or the vehicle electronic control unit. At this time, the number of controllers 30 can be reduced and the corresponding cost can be reduced, and the failure rate of the electric drive upper assembly 1 can be reduced. In addition, the power generation efficiency of the generator 200 can be improved. Among them, the electronic controller is referred to as VCU, and the vehicle electronic control unit is referred to as ECU.

[0033] In addition, Figure 1 As shown, the electric drive upper assembly 20 also includes: a drive motor 202, which is electrically connected to the controller 30. The drive motor 202 can mainly convert electrical energy into mechanical energy, or convert mechanical energy into electrical energy. The drive motor 202 is electrically connected to the controller 30, and the controller 30 can ensure that the speed, torque and direction of the drive motor 20 are accurately controlled, and at the same time can achieve efficient energy recovery and utilization.

[0034] It should be noted that if Figure 1 As shown, the electric drive upper assembly 1 also includes: a stirring component 40, and the drive motor 202 cooperates with the stirring component 40. The stirring component 40 can perform operations such as mixing, stirring, and dissolving in scenes such as industrial production or laboratories. The drive motor 202 cooperates with the stirring component 40 to drive, and the electric energy of the battery 201 is transmitted to the drive motor 202, and the drive motor 202 rotates, and the drive motor 202 drives the stirring component 40 to work, and energy transmission can be achieved at this time.

[0035] In addition, if Figure 1 As shown, the electric drive upper assembly 1 also includes: a reducer 50, which is connected between the drive motor 202 and the stirring assembly 40. The reducer 50 can mainly reduce the rotation speed, increase the output torque, reduce the inertia of the load, and improve the load capacity of the equipment. The reducer 50 is connected between the drive motor 202 and the stirring assembly 40, so that the reducer 50 can reduce the rotation speed transmitted by the drive motor 202, thereby meeting the working rotation speed of the stirring assembly 40, making the stirring assembly 40 work more reasonably.
