Detailed Description
The invention is further illustrated by the following examples:
the knob type P-gear operating mechanism is different from the key P-gear operating mechanism.
The knob type P-gear control mechanism is characterized in that a knob in the rotating mechanism is used for driving a body mechanism below to rotate through an operation knob, when the rotation angle reaches a trigger condition, a sensor detects that the body mechanism moves and then sends a high-level signal, a gear shifter receives the high-level signal and then sends a P-gear entering signal, a gear shifting actuator control unit is used for combining the current speed of a vehicle, the current gear signal, the opening condition of an accelerator pedal and the unlocking key condition to judge whether the gear enters the P gear, and if the gear shifting actuator is judged to be executed, a motor of the gear shifting actuator is driven to rotate to drive a pawl to buckle a gear on an output shaft to form mechanical locking.
The button type P keeps off operating mechanism refers to that through pressing the button in the mechanism, contact button in the circuit board below is put through the drive of operation button, when the stroke of pressing reaches trigger condition, contact in the circuit is put through, P button mechanism sends high level signal, the selector sends and gets into P and keep off the signal after receiving this high level signal, combine current speed by the executor control unit that shifts, current fender position signal, accelerator pedal aperture condition and unblock button condition judge whether get into P and keep off, if judge to carry out, then drive the executor motor rotation drive of shifting sets up the pawl and withhold the gear on the output shaft and form mechanical locking in the gearbox inside.
The P gear operating mechanism is only responsible for entering the P gear and providing P gear display, and if the P gear is to be out, the shifter is required to be operated to realize the operation of entering other gears from the P gear when the P gear is out of the gear and the P gear shifting condition is met. Therefore, the knob type P-gear operating mechanism or the button type P-gear operating mechanism is only responsible for entering the P gear. Thus, the P-gear operating mechanism is operated again when the current gear is in the P gear, and the vehicle still maintains the P gear.
The knob type P-gear control mechanism can be designed to be monostable or multistable according to requirements.
Multistable is distinguished from monostable.
Multistable means that there are a plurality of stable positions of the knob during rotation, so there are no extreme positions for multistable. Monostable means that only a single stable position exists in the rotating process of the knob, and when the user operates the knob to rotate, the knob can rebound to the stable position after the user finishes entering the P gear operation and loosens hands.
The monostable and multistable arrangement is achieved by the different tooth forms of the tooth grooves.
The number of the monostable tooth-shaped grooves is less, generally two, the monostable tooth-shaped grooves are arranged at symmetrical positions, the tooth shapes are at dead point positions, when the operation knob rotates, the gear pin (the stop pin) rotates to the tooth-shaped dead point position of the tooth-shaped groove, the knob cannot continue to rotate, after the hand is loosened, the lateral component force between the compression spring of the gear pin (the stop pin) and the tooth-shaped groove pushes the knob to return to the original position, and the tooth-shaped groove returns to the steady position.
The multistable tooth-shaped grooves are more in tooth shape, the tooth shape is not provided with dead point positions, when the operation knob rotates, the stop pin moves linearly along the tooth shape, the spring is compressed, the operation hand feeling is provided, and when the operation knob passes through one tooth shape, the operation hand feeling is provided once, and one operation is completed.
The rotating order of the multistable knob type P-gear operating mechanism can be set according to the rotating scale, and the rotating order is 9 times when the rotating scale is set to be 40 degrees if the whole circumference is 360 degrees. But in theory the knob may be rotated an infinite number of times through 360.
The arrangement of the rotary scale is also structurally achieved by designing the number of teeth of the tooth-shaped grooves, which are generally repetitive and continuous in shape for multistable knob operating mechanisms.
The fixing points can be set according to the arrangement space.
