Embodiment 1
[0016] Please also refer to Figure 1, as shown in the figure, the electric vehicle includes a vehicle frame 1 and a switch handle 2 installed on the vehicle frame 1, a vehicle control module 3, a motor 4, a motor drive module 5, and a protection switch device 6. The support foot 7, the protection switch device 6 is connected in series between the switch handle 2 and the vehicle control module 3 or between the motor 4 and the motor drive module 5 through wires.
[0017] In this embodiment, the protection switch device 6 is connected in series between the switch handle 2 and the vehicle control module 3 through wires. Specifically, the protection switch (inductive switch) device 6 is installed on the vehicle frame in front of the driver. In this way, the switch of the protection switch (sensing switch) device 6 can be controlled by the state of the driver, that is, when the driver of the electric vehicle sits on the seat cushion, the protection switch (sensing switch) device 6 se...
Embodiment 2
[0021] The difference between this embodiment and Embodiment 1 is that the installation position of the protection switch device is different. In this embodiment, the protection switch device is installed near the foot 7 of the vehicle frame 1, and the protection switch is driven by the foot of the vehicle frame. When the legs are put down, the legs drive the protection switch device to be in the disconnected state, and when the legs of the electric vehicle are retracted, the legs drive the protection switch device to be in the closed state, so even if the electric vehicle is parked and the electric door handle is turned, the electric vehicle will not rush out accidentally.
Embodiment 3
[0023] The difference between this embodiment and Embodiment 1 is that the installation position of the protection switch device is different. In this embodiment, the protection switch device is installed on the support foot 7 of the vehicle frame, and the protection switch device is in the off state when the support foot of the electric vehicle is put down. , the protection switch device is in a closed state when the electric vehicle legs are retracted, so even if the electric vehicle is parked, the electric vehicle will not be accidentally rushed out even if the electric door handle is turned.
