Description

Technical Field

[0001] The utility model relates to the technical field of electric motorcycle control systems, in particular to a cover shell of an electric motorcycle controller. Background Art

[0002] Electric motorcycles, also known as electric motorcycles, are a type of two-wheeled or three-wheeled electric vehicles.

[0003] In the prior art, the motor controller, inverter, and encoder usually each require a fixing unit and a protective cover, resulting in a complex structure and a large overall size. Since the motor controller, inverter, and encoder are not concentrated in one place, they need to be connected by wire harnesses, and the wire harness path is long.

[0004] For household transportation tools such as electric motorcycles, portability and reliability are important considerations. The larger size and structure of the electric motorcycle controller will increase the weight of the vehicle, reducing the convenience and experience of use. In addition, if there is a problem with the connected wiring harness, the vehicle will not be able to be used normally, or even cause an accident.

[0005] Therefore, how to improve the integration level needs to be studied. This application will propose a cover for an electric motorcycle controller, which can be used to install and accommodate a motor controller, an inverter, and an encoder, and provide an installation structure for the required connector, thereby facilitating improving the integration level. Summary of the invention

[0006] In view of the shortcomings in the existing production technology, the applicant provides a cover for an electric motorcycle controller, which can be used to install and accommodate a motor controller, an inverter, and an encoder, and provides a mounting structure for the required connectors, thereby facilitating improved integration.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A cover shell of an electric motorcycle controller includes a shell that plays an overall protective role. One side of the shell is open, and the side where the opening is located is used to connect with the end cover plate of the motor to close the opening. The inner side of the shell is provided with an inner wall for installing and accommodating the motor controller, inverter, and encoder. The outer side of the shell is provided with fixing bolt mounting holes, bolt mounting avoidance grooves, heat dissipation ribs, high-voltage electric connector mounting bosses, low-voltage electric connector mounting bosses, and waterproof breathable valve mounting bosses.

[0009] As an improvement, one end of the shell is semicircular, and the other end is a rectangle with a height equal to the diameter of the semicircle. The corners of the rectangle are rounded. One side of the shell is open, and the other side has a side wall with a height equal to the overall thickness of the shell.

[0010] As an improvement, the inner side wall is a plane, and the circumferential direction of the plane is the same as the shell contour.

[0011] As an improvement, the fixing bolt mounting holes are distributed on the edge of the shell contour, and the mounting holes are round holes.

[0012] As an improvement, the bolt mounting hole avoidance groove is an arc-shaped concave surface concentric with the fixing bolt mounting hole. The length of the arc-shaped concave surface is the same as the thickness of the shell. The outer side of the bolt mounting hole avoidance groove appears to be sunken from the shell surface, and the inner side of the bolt mounting hole avoidance groove appears to be protruding toward the inside of the shell to form an axial column.

[0013] As an improvement, it also includes heat dissipation ribs, which are distributed on a large plane outside the shell.

[0014] As an improvement, the high-voltage electrical connector mounting boss is distributed on the outside of one semicircular end of the shell, is cylindrical and protrudes outward.

[0015] As an improvement, the low-voltage electrical connector boss is distributed on the outside of one end of the rectangular shell. The low-voltage electrical connector boss is rectangular and protrudes outward. There is a sunken platform at the relative position between the inner side of the shell and the low-voltage electrical connector boss.

[0016] As an improvement, the waterproof and breathable valve mounting boss is distributed on the outside of one end of the rectangular shell, and the waterproof and breathable valve mounting boss is U-shaped and protrudes outward.

[0017] The beneficial effects of the utility model are as follows:

[0018] The utility model includes a shell for overall protection, one side of the shell is open, the side where the opening is located is used to connect with the end cover plate of the motor to close the opening, and the inner side of the shell is provided with an inner side wall for installing and accommodating the motor controller, inverter, and encoder, so the structure is simple and reasonable, and the installation is convenient. The outer ring of the shell is distributed with mounting holes, which are connected with the end cover plate of the housing of the drive motor through bolts. Each bolt hole has a corresponding bolt installation avoidance groove, which is convenient for the entry of bolts and wrenches. The components such as the motor controller and inverter are directly fixed in the cover shell, and can be installed in place once, eliminating the secondary assembly of the special bracket; and the outer side of the shell is provided with heat dissipation ribs, which dissipate the heat of the motor controller and inverter into the atmosphere; the high-voltage electrical connector mounting boss on the outer circumferential direction of the shell is used to install the high-voltage electrical connector, the low-voltage electrical connector mounting boss is used to install the low-voltage electrical connector, and the waterproof breathable valve mounting boss is used to install the waterproof breathable valve, thereby solving the external electrical connection requirements required for the centralized installation of the motor controller, inverter, and encoder, and the waterproof breathable valve solves the safety problem, achieving the integration purpose while taking into account safety.

[0019] 2. The utility model has a good protective effect on electronic components. Components such as motor controller, inverter and encoder are all located inside the housing cavity. After the housing and the frame are fixed, all components are protected. Because the motor controller, inverter and encoder can be concentrated together by using the housing disclosed in the present invention, the connectors and connecting wires between the components are also located inside the housing.

[0020] 3. The utility model can save a lot of installation space for the entire control system. The motor controller and inverter circuit board are directly installed and fixed in the cover of the present invention, without the need for separate motor controller and inverter mounting brackets and protective housings, with a compact structure and high space utilization. The cover is fixed on the end cover plate of the housing of the drive motor, and the encoder of the drive motor can be accommodated and installed in the cover, thereby playing a protective role. There is no need to configure a separate encoder cover, saving the installation space of the encoder cover. BRIEF DESCRIPTION OF THE DRAWINGS
