Self-locking rotary knob gearshift device

Abstract

The invention provides a self-locking rotary knob gearshift device comprising a rotary knob, a gearshift control assembly and a self-locking control assembly. The gearshift control assembly and the self-locking control assembly share the same shift column support; the rotary knob is fixedly connected with the shift column support; a gearshift control panel of the gearshift control assembly detects a photoelectric signal of a photoelectric sensor and matches a corresponding shift; when the gearshift control assembly is switched to a preset shift, a self-locking slide block of the self-locking control assembly is inserted into a self-locking spacing ring; and the rotary knob is mechanically locked in the preset shift.

Description

technical field [0001] The invention relates to a gear shifting device for a passenger car, in particular to a self-locking knob shifting device, which is one of the main spare parts of the power system of a passenger car. Background technique [0002] With the continuous development of passenger car technology, the power system of passenger cars is no longer limited to internal combustion engines such as gasoline engines or diesel engines, but directly uses electric motors as the main power source or auxiliary power source. Green and environmentally friendly pure electric vehicles and hybrid vehicles with low emissions and strong power are emerging. Traditional passenger car engines are generally matched with mechanical shifting devices. With the further development of technology, electronic shifting devices compatible with hybrid vehicles and pure electric vehicles have emerged as the times require. The electronic shifting device takes the detection of electric signals as...

Problems solved by technology

[0004] In other words, none of the existing knob-type electronic shifting devices or handle-type electronic shifting devices can lock the gear position, which may cause the shifting device to be blocked by the driver, minors on the passenger seat, etc. Driving safety hazard caused by misoperation

Therefore, it is necessary to propose an electronic shifting device that can realize gear locking, so as to avoid driving safety hazards caused by misoperation of the shifting device.
