Knob type gear shifting switch of automobile

Abstract

The invention discloses a knob type gear shifting switch of an automobile. The knob type gear shifting switch of the automobile comprises a housing, a knob and a gear seat, wherein the gear seat is fixed to the housing, and a gear mark is arranged on the gear seat; the knob is rotatably mounted on the gear seat. The knob type gear shifting switch of the automobile is characterized in that a rotating wheel is mounted on the knob; a plurality of arc-shaped grooves are uniformly formed in the periphery of the rotating wheel; an oscillating arm is arranged in the housing, and one end of the oscillating arm is in contact with the rotating wheel while the other end of the oscillating arm is equipped with a magnet; a hall sensor which is corresponding to the magnet is arranged in the housing, andthe hall sensor is connected to a single-chip microcomputer; a hall sensor triggering standing time determining module is arranged in the single-chip microcomputer; if the standing time of the knob is not less than the set time, the gear shifting operation is valid; if a gear is switched to the first gear or the top gear, the knob is rotated reversely, and the gear can be directly switched to a neutral gear. The knob type gear shifting switch of the automobile is outstanding in gear determining capacity, and accurate to shift the gears, and mis-operation can be effectively prevented; the knobtype gear shifting switch of the automobile is convenient to use, and high in safety; and the service life can be effectively prolonged.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a knob type automobile shift switch. Background technique [0002] The car shift switch is usually in the form of a knob to shift gears. When shifting gears, it is necessary to turn the knob and turn it to the designated gear to give instructions to the driving state. When the existing knob-type car shift switch is turned , just shift gears, resulting in frequent shifts between the various gears, which affects the service life of the shift switch, especially when there are children in the car, turning the knob out of curiosity will also shift gears, making the car drive Cause safety hazards, because different drivers operate at different speeds, which may cause the car to start or stop before the switch is rotated in place, and safety accidents are prone to occur; Rotate the knob so that it cannot stay at the designated position, so the car cannot accurately judge its designation, and...

When the existing knob-type car shift switch is turned , just shift gears, resulting in frequent shifts between the various gears, which affects the service life of the shift switch, especially when there are children in the car, turning the knob out of curiosity will also shift gears, making the car drive Cause safety hazards, because different drivers operate at different speeds, which may cause the car to start or stop before the switch is rotated in place, and safety accidents are prone to occur; Rotate the knob so that it cannot stay at the designated position, so the car cannot accurately judge its designation, and it is also prone to misoperation, which has certain safety hazards

At the same time, the knob is also prone to damage
