Problems solved by technology

[0003] Since the existing electronically controlled shifter realizes the operation lever to control the shifting operation through the card slot design of the panel, when it is necessary to overtake on an uphill, downhill, long slope or at a high speed per hour, the signals of each sensor cannot be used for each gear. It is difficult for novice drivers to accurately control the shifting during the shifting process, and it is difficult to achieve fast shifting and deceleration. Novice drivers will decelerate through the brakes. Using the brakes over time can overheat the discs and cause the brakes to fail

Abstract

The invention relates to the field of new energy vehicles, in particular to an electric control gear shifting device for a new energy vehicle. The device comprises a bottom frame, an arc-shaped protection frame, cover plates, a rotating assembly, a manual gear shifting assembly and the like; and an arc-shaped protection frame is fixedly installed on the top of the bottom frame, the cover plates are fixedly installed on the two sides of the bottom frame, the two cover plates are jointly and rotationally connected with the rotating assembly, and the arc-shaped protection frame is rotationally connected with the manual gear shifting assembly. When overtaking is needed on a long slope or at a high speed per hour, a transmission deflector rod can be controlled to change the rotating direction, the moving direction of a convex circular ring and the moving direction of devices on the convex circular ring can be adjusted, gear reduction is conducted on an automobile to reduce the speed of the automobile, the braking performance is guaranteed, and the situation that braking failure is caused by overheating of a brake disc when a brake is used for a long time is avoided.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to an electronically controlled shifting device for new energy vehicles. Background technique [0002] With the development of the shifter industry, electronically controlled shifters have become more and more popular, and the so-called electronically controlled shifters refer to touching the sensors located in various positions through the toggle of the operating lever, thus The signals of each sensor correspond to each gear position, and the shift mechanism is driven by a motor to drive the shift fork to move the synchronizer gear sleeve, so that the synchronizer gear sleeve cooperates with the driving gear of the corresponding gear position to realize the shift operation. The operating lever of the control shifter is reset to the N position after each toggle. [0003] Since the existing electronically controlled shifter realizes the operation lever to control the shifting oper...
