In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one or more of the parts with the same structure or function are schematically drawn or only one or more of them are marked.

[0046] refer to Figure 1 and Fig.14 The present application provides a switch assembly for installation on an electric vehicle, the electric vehicle comprising a handlebar, the switch assembly comprising:

[0047] The base 10 is used to be mounted on the handlebar of the electric vehicle;

[0048] A mounting shell 20, mounted on the base 10, wherein the mounting shell 20 has a first cavity;

[0049] A plurality of function switches 30, mounted on the base 10 and / or the mounting shell 20, wherein the function switches 30 have an operating portion for the rider of the electric vehicle to operate;

[0050] The circuit board 40 is installed in the first cavity and is electrically connected to the function switch 30 and the central control unit 62 of the electric vehicle.

[0051] Fig.12 and Fig.13 In the example, five function switches 30a, 30b, 30c, 30d, and 30e are shown. Fig.13 As well as the above technical solution, the circuit board 40 is electrically connected between the multiple function switches 30 and the electric vehicle central control unit 62, and the control signals of the multiple function switches 30 can be collected on the circuit board 40 and transmitted to the central control unit 62, which is conducive to reducing the use of wiring harnesses. Among them, by setting the mounting shell 20, it can play a role in waterproofing and dustproofing, protecting the circuit board 40 from rain and dust, which is conducive to improving the service life of the circuit board 40. By installing the mounting shell 20 on the base 10, the circuit board 40 and the function switch 30 are both installed on the base 10, which is conducive to reducing the distance between the circuit board 40 and the function switch 30, and then realizing the electrical connection between the two while reducing the clutter of the connecting harness between the two.

[0052] Among them, the operating part of the function switch 30 can be in the form of a push button, a dial wheel or a slider. The operating part can have multiple control gears, and the operating part can reach different gears by pressing, toggling, and sliding. The function switch 30 can also include a contact piece corresponding to the control gear.

The electrical signal is sent to the circuit board 40, and after being processed by the control chip on the circuit board 40, it is sent to the central control unit 62 of the electric vehicle. The central control unit 62 recognizes the signal and drives the corresponding function of the vehicle to turn on. Specifically, when the function switch 30 is operated and released, a high and low level switching signal can be output. The high and low level change signal is received at the corresponding pin of the IC chip on the circuit board 40, converted into a digital signal and output from the output interface of the switch component. The central control unit 62 of the electric vehicle is not limited to an instrument, a VCU (vehicle controller), a controller, an ECU (electronic control unit), etc.
