The working principle of the gravity inflatable pneumatic parking spot lock implementation mode of the invention is as follows:
1. initial position state:
the position is the neutral position of the combined electromagnetic valve in the power-off state, the piston of the combined air cylinder is positioned at the middle position of the front section due to the action of the return spring, the inclination angle of the baffle is positioned in the middle range, the height of the highest point of the baffle from the ground is smaller than the maximum height of the vehicle for crossing an obstacle, at the moment, the vehicle tire can roll over the baffle, the tire presses the baffle due to the weight of the vehicle, the motion of a four-bar mechanism consisting of the machine plate, the baffle, the rocker arm and the connecting bar is acted on the piston rod of the combined air cylinder by the pin shaft, the piston rod is retracted towards the bottom of the front section, the air in the original cylinder barrel is compressed, and the compressed air is input into the air storage tank of the rear section through the one-way valve in the middle position of the combined electromagnetic valve and stored; once the vehicle tyre is driven away from the baffle, the piston is pushed back under the action of the return spring, new air is sucked into the cylinder barrel under the action of the middle section air filter and the one-way valve channel, the piston returns to the middle position of the front section, the baffle also rises to the original middle position, and the parking spot lock is restored to the original position; if the vehicle tyre repeatedly presses the baffle, the front section repeatedly inflates the rear section air storage tank; if the pressure in the gas storage tank is too high, gas overflows from the safety valve; this state may also be referred to as an "inflated" state.
2. Baffle raised state:
after a tire of the vehicle passes, the induction control device will stop the vehicle correctly? Identifying and sending out an instruction to enable the combined electromagnetic valve to be positioned at the right position, wherein a lower air cavity connecting port of a piston at the front section of the combined air cylinder is communicated with an air storage tank connecting port at the rear section, compressed air in the air storage tank enters a lower air cavity of the piston at the front section, and pushes a piston rod to extend out, so that a pin shaft is pushed, a 'dead point' of a mechanism is skipped by a point (when a rocker arm and a connecting rod are in a straight line, the position of the pin shaft is the 'dead point'), at the moment, the inclination angle of a baffle plate is the largest, but the height of the highest point from the ground cannot be larger than the minimum ground clearance of a vehicle, namely the highest point of the baffle plate cannot touch a chassis of the vehicle, and therefore, the baffle plate cannot be crossed when a vehicle tire runs reversely; the pin shaft bypasses some of the dead points, so even if the combined solenoid valve is de-energized, the combined solenoid valve returns to the neutral position, but the baffle plate does not drop, so this state may also be referred to as a "lock-in" state.
3. Baffle down state:
when a vehicle stopped on a parking space needs to be driven out of a warehouse, a driver needs to send out a driving signal or pay fees, the induction control device timely sends out an instruction after receiving information, so that the combined electromagnetic valve is shifted to the left position, an upper air cavity connecting port of a piston rod of the front section of the combined air cylinder is communicated with an air storage tank connecting port of the rear section, compressed air in the air storage tank enters an upper air cavity of the piston rod of the front section, the piston rod is pushed to extend, the piston rod is pushed to retract, and therefore a pin roll is pulled to leave a dead point, and a baffle descends, and the highest point of the baffle is lowered to the height which can be crossed by a vehicle tire; when the induction control device recognizes that the vehicle exits the parking space, the induction control device sends an instruction to cut off the power, so that the combined electromagnetic valve returns to the middle position, the piston at the front section returns to the middle position due to the action of the return spring, the baffle plate also returns to the original middle range, and the parking space lock returns to the initial position state to prepare for the next working cycle.
The pneumatic energy of the gravity inflatable pneumatic parking spot lock disclosed by the invention also comes from the conversion of the driving energy of vehicles entering and exiting a parking lot each time and the weight of the vehicles, the driving energy of the sensing device and the electromagnetic valve is provided by an internal small battery, and the battery needs to be replaced or timely charged after the electric quantity of the battery is consumed or a solar charger can be installed for timely charging.
The gravity inflatable pneumatic parking lot gate and the gravity inflatable parking lot lock can be widely applied to social, residential district, personal parking lots and network reserved parking systems.
