Monostable knob shifter

Abstract

The invention provides a monostable knob shifter comprising a rotating shaft and a base. The rotating shaft is installed in the base; the rotating shaft can clockwise or anticlockwise rotate to a first site or a second site from the midpoint position and can automatically return to the midpoint position so as to achieve switching among a P gear, an R gear, an N gear and a D gear. The monostable knob shifter further comprises a key, an unlocking rod and a containing hole; the containing hole is formed in the rotating shaft in a vertically-penetrating mode; the key is arranged in the containing hole and cannot rotate relative to the rotating shaft; one end of the unlocking rod is connected to the lower side of the key, and the other end of the unlocking rod is provided with a first clamping piece; and the base is provided with a second clamping piece. If the key is not pressed down, the first clamping piece and the second clamping piece are mutually clamped, and the rotating shaft cannot rotate relative to the base; and if the key is pressed down, the first clamping piece is separated from the second clamping piece, and the rotating shaft can rotate relative to the base. The monostable knob shifter is provided with an anti-misoperation design, so that the safety of the shifter can be improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a monostable knob shifter. Background technique [0002] At present, the knob shifters in the prior art mainly have two structures. The first such as figure 1 As shown, it has four absolute position gears, namely P, R, N, D gears. However, in order for consumers to perceive the gear position, each gear must be carefully designed to ensure that each gear has a different feel. In addition, this kind of knob shifter cannot meet the requirements of automatic parking or automatic driving. [0003] The second such as figure 2 As shown, it is a monostable structure. The midpoint position of the shifter (ie point O) is the stable position. Rotate clockwise from the midpoint to reach the L1 position, and rotate clockwise from the midpoint for two Rotate down to the L2 position, turn counterclockwise once from the midpoint to reach the R1 position, turn counterclockwise from the midpoint p...

Problems solved by technology

This kind of knob shifter can meet the needs of automatic parking or automatic driving, but this kind of knob shifter has no locking structure. When the driver rotates the knob due to misoperation, the gear shifter will switch gears , causing traffic accidents
