Problems solved by technology

[0002] At present, electric motorcycles and electric bicycles in the known technology do not have start protection devices, and they can be driven by turning the electric door handle after inserting the key. Although such a simple operation will bring a lot of convenience to the driver, it often leads to misoperation, causing Some unexpected accidents, such as the car is parked, the key is not pulled out, the electric door handle is accidentally turned, or the electric car is parked and the child plays on the electric car and turns the electric door handle, all of which will cause the electric car to rush out accidentally

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.

Abstract

The invention provides an electric motorcar with a start-up protection device, and relates to the field of electric motorcars. After a key is inserted in, an electric motor car or an electric bicycle can be driven through rotating a switch handle, but when the driver is off the electric motorcar, as the key is not pulled out, accidental rushing out of the electric motorcar can be caused due to careless rotation of the switch handle, so that a protection switch device is added in a driving circuit of the electric motorcar, and linkage of the switch handle or a motor is controlled through the protection switch device, as a result, during unmanned driving, circuit connection of the switch handle or the motor is cut off through the protection switch device, and accidental rushing out of the electric motorcar caused by misoperation is prevented. In order to prevent misoperation of the electric motorcar after parking, the protection switch device 6 is mounted on a motorcar frame in front of a driver, when the driver is on the electric motorcar, an induction switch induces the driver, and the protection switch device is in a closed state, and when the driver is off the electric motorcar, the induction switch induces getting-off of the driver, and the protection switch device is in an off state, so that accidental rushing out of an electric motorcar due to misoperation is prevented.

Description

technical field [0001] This patent relates to the field of electric vehicles, in particular to an electric vehicle with a starting protection device. Background technique [0002] At present, electric motorcycles and electric bicycles in the known technology do not have start protection devices, and they can be driven by turning the electric door handle after inserting the key. Although such a simple operation will bring a lot of convenience to the driver, it often leads to misoperation, causing Some unexpected accidents, such as not pulling out the key after the car is parked, accidentally turning the electric door handle, or children playing on the electric car and turning the electric door handle after the electric car is parked, will cause the electric car to rush out accidentally. Contents of the invention [0003] The purpose of this patent is to overcome the deficiencies of the above-mentioned prior art, and provide a simple, safe and reliable electric vehicle with ...
