Description

Technical Field

[0001] This utility model belongs to the field of electric motorcycle technology and relates to an integrated power module for electric motorcycles. Background Technology

[0002] Motorcycles are a common mode of transportation, primarily powered by gasoline, with an engine driving the tires. However, with the continuous development of new energy technologies, electric motorcycles have gradually appeared on the market. Compared to traditional gasoline motorcycles, the cost of charging electric motorcycles is lower than the cost of refueling. Electric motorcycles also produce no exhaust fumes, making them more environmentally friendly, and they are quieter during operation. Therefore, electric motorcycles are being continuously promoted and popularized.

[0003] The power system of an electric motorcycle mainly consists of a battery, a controller, and a motor. During the assembly process of an electric motorcycle, because there are no standardized requirements for the installation methods and positions of these structures, different manufacturers will have different installation methods for these structures. Usually, the above structures are installed in various parts of the motorcycle body, which will lead to maintenance troubles, increase the time required for assembly, and reduce production efficiency. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the current technology by proposing an integrated power module for electric motorcycles. The technical problem to be solved by this utility model is: how to quickly assemble the power system on an electric motorcycle.

[0005] The objective of this utility model can be achieved through the following technical solution: an integrated power module for an electric motorcycle, comprising a housing, the housing being composed of a battery compartment and a power compartment, the battery compartment containing a battery pack, the power compartment containing a fixed motor and a controller, and the motor having an output shaft at its end.

[0006] In this design, the battery pack is housed inside the battery compartment, which protects the internal battery pack. The battery pack is connected to the controller and motor, providing them with DC power. The controller receives commands from the handlebars and controls the motor's start, operation, forward and backward movement, speed, and stop, as well as other electronic components on the electric motorcycle. After the motor starts, it drives the output shaft to rotate. Through this method, the outer shell structure is designed to house the battery pack, controller, and motor, connecting the three main structures of the power system together. These structures are assembled into a modular structure, which can be directly applied to the assembly process of the electric motorcycle, eliminating the need for assembly by the manufacturer. This enables rapid installation and facilitates the conversion of motorcycles from gasoline to electric vehicles.

[0007] In the integrated power module of the aforementioned electric motorcycle, a gearbox is connected to the power compartment, and the output shaft extends into the gearbox. Inside the gearbox are a rotatable shaft and a gear set. One side of the gear set meshes with the shaft, and the other side meshes with the output shaft. After the motor drives the output shaft to rotate, the output shaft drives the meshing gear set to rotate, which in turn drives the shaft to rotate, outputting torque and driving the rear wheel to rotate.

[0008] In the integrated power module of the aforementioned electric motorcycle, the motor and controller are housed adjacent to each other in the power compartment, and the battery pack is detachably connected to the battery compartment. The adjacent placement of the controller and motor reduces the length of the connecting wires between the two structures, thus minimizing current loss. The battery pack is connected to the battery compartment via a snap-fit ​​structure or a guide rail slot, and a quick-release structure can be provided for easy battery pack replacement.

[0009] In the integrated power module of the aforementioned electric motorcycle, a water tank is fixedly mounted on the outer side of the outer shell. The water tank has an outlet pipe and an inlet pipe. A flow channel is located inside the power compartment, with both ends connected to the outlet pipe and the inlet pipe, respectively. Water from the water tank flows out of the outlet pipe, into the flow channel within the power compartment, then into the inlet pipe, and finally back into the water tank, continuously circulating in a cycle.

[0010] In the integrated power module of the aforementioned electric motorcycle, the flow channel is located on the side near the controller. An inlet is located inside the flow channel, and a cooling water channel is located inside the outer wall of the motor, surrounding the outside of the motor. The inlet is connected to the cooling water channel. The controller's side is close to the flow channel, which helps cool the controller. Water flowing inside the flow channel enters directly into the cooling flow channel inside the motor's side wall through the inlet, thus dissipating heat from the motor.

[0011] In the integrated power module of the aforementioned electric motorcycle, a water pump is installed on the water outlet pipe. The water pump is fixedly connected to the outer wall of the casing. A water tank cover and a water reservoir are fixedly connected to the water tank, with the water tank cover located outside the water tank and water reservoir. The water pump provides the power source, drawing water from the water tank and injecting it into the flow channel. The water pump can be a DC variable speed pump, which can automatically adjust its speed according to the motor temperature signal. The expansion tank also serves to compensate for the coolant. When the coolant expands or contracts due to temperature changes, the expansion tank can absorb or release the coolant to maintain the pressure balance within the system.

[0012] In the integrated power module of the aforementioned electric motorcycle, a charging device is fixedly mounted on the top of the power compartment. The charging device contains both a fast charging port and a slow charging port. Two charging modes are available for the user to choose from.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. In this solution, the outer shell structure is used to house the battery pack, controller, and motor, connecting the three main structures in the power system together. The above structures are integrated into a modular structure, which can be directly applied to the assembly process of electric motorcycles, eliminating the need for assembly manufacturers to assemble the above structures separately, thus achieving rapid installation and facilitating the promotion of electric conversion in the motorcycle industry. The integrated module facilitates later replacement or testing and reduces the complexity of wiring harnesses. Attached Figure Description

The controller 2 can receive commands from the handlebars and control the motor 3's start, operation, forward and backward movement, speed, and stop, as well as other electronic components on the electric motorcycle. After the motor 3 starts, it drives the output shaft 3a to rotate, which in turn drives the meshing gear set 4b to rotate. The gear set 4b then drives the rotating shaft 4a to rotate, outputting torque and driving the rear wheel to rotate. The water tank 5 structure installed on the battery compartment 1a can cool the controller 2 and the motor 3.

[0025] In the above method, the outer casing 1 is used to house the battery pack 1a1, controller 2 and motor 3, which connect the three main structures in the power system together and assemble the above structures into a modular structure.
