Detailed Description
The invention is further illustrated by the following examples:
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. The 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 P-button mechanism integrated on the shift lever or shift knob differs from the P-button mechanism in the form of a separate assembly in terms of the setting of the operating force. The P-button operating force setting integrated on the shift handle or shift knob is typically reduced by 1/3 compared to the P-button operating force alone.
The P-gear operating mechanism often adopts a key structure, is usually arranged on a gear shifting handle or a gear shifting knob, is limited by an arrangement space, and is integrated on the gear shifting handle or the gear shifting knob, and the P-key mechanism in the independent assembly form adopts a four-contact key.
The resilience force of the four-contact button type P-gear operating mechanism is provided by a silica gel button on the circuit board. When a user presses the key cap, the key cap drives the key support to move downwards, the silica gel keys below the compression support deform, and the compressed amount of the silica gel keys provides a pressing operation stroke. After the hands are loosened, the silica gel keys are restored to the original state, and the resilience provides operation force and rebound sound.
The resilience force and rebound sound of the key-type P-gear control mechanism can be set, and can be realized by adjusting the material, contact area and hardness of the silica gel key, and the key-type P-gear control mechanism can be adjusted according to user experience.
The number of key contacts below the key support can be set, and the key support is designed according to the area and the shape of the key cap of the P key input by the modeling trim, considering the number and the arrangement positions of the contacts. When the area of the key blocking cap is larger, a plurality of silica gel key contacts are arranged between the circuit board and the key support, and meanwhile, the arrangement positions are dispersed uniformly, so that the key resilience force is ensured to be uniform.
The P-gear control mechanism of the independent assembly needs a fixed structure, and the fixed point can be automatically arranged according to the space and modeling input requirements.
