Description

Technical Field

[0001] This invention relates to an automotive flood control and disaster relief airbag, belonging to the field of flood control and disaster relief emergency equipment. Background Technology

[0002] During flood prevention and control emergency self-rescue or rescue operations, there may be dangerous situations where the vehicle is submerged by floodwaters while parked, or is submerged or swept away by floodwaters while in motion. Summary of the Invention

[0003] The purpose of this invention is to address the problems raised in the background art by designing a car flood prevention and control airbag cushion, which is installed on the top or bottom of the car. When the car is hit by a flood or submerged, the airbag cushion will automatically sense and inflate automatically or manually to float the car, preventing drowning casualties and damage to the car. It can also be used to drive the car to a safe area in the flood to escape.

[0004] The technical solution of this invention is as follows: A car flood control airbag includes a bottom-type airbag and a top-type airbag, an air pump, a vacuum pump, a high-pressure air hose, a vacuum hose, a positive power cable, a built-in negative ground power supply for the car, an automatic power switch for the flood sensor, independent manual switches for the air pump and vacuum pump, a remote control switch, a fixing strap on the bottom-type airbag, an airbag support, an airbag retraction lock, and an airbag retraction lock opening. The top-type flood control airbag features a multi-section, customizable telescopic horizontal fixing rod and a rod base fixing plate with pulleys at both ends, a multi-section, customizable telescopic vertical fixing rod and a lever, a lifting clip, a rotating shaft and a locking ring, a clip crank arm, a T-shaped shaft, a T-shaped shaft end and a double shaft end, a fixing clamp, a robotic arm and an arm base fixing plate, and a robotic arm connection. The system includes pins and their upper flat pads and open locking pins, a three-way air valve for the robotic arm, a vertical rod air valve, a horizontal rod air inlet check valve, a horizontal rod vacuum pump suction check valve, and airbag inlet / extraction valves. The bottom-mounted vehicle flood control airbag is fixed under the floor of a high-chassis vehicle, while the top-mounted vehicle flood control airbag is fixed to the top of the vehicle. The air pump and vacuum pump are installed in the trunk of the vehicle. The automatic power switch for the flood sensor is installed under the trunk floor. Independent manual switches for the air pump and vacuum pump, and a remote control switch are installed in the driver's cab. The positive power inlet wires of the automatic and manual switches are connected to the positive terminal of the vehicle's battery. The positive power outlet wire of the automatic switch is connected to the air pump. The positive power outlet wires of the independent manual and remote control switches are connected to the motors of the air pump and vacuum pump, respectively. All negative power supplies... All components are automatically connected to the car's negative ground. When the water level sensor detects a dangerous water level, the automatic power switch automatically connects the air pump power, and the air pump starts working. For manual or remote control, pressing the power switch or remote control switch manually will connect the air pump or vacuum pump power, respectively, allowing the air pump or vacuum pump to operate. The bottom-mounted flood control airbag pad consists of two parts, left and right, with a gap in the middle to avoid the engine exhaust muffler. The entire unit is fixed to the bottom of the car floor using front and rear upper fixing straps and a lower airbag pad support. The upper fixing straps are fixed to the upper part of the airbag pad and the bottom of the car floor. Each end of the fixing strap is equipped with an airbag retraction lock, i.e., an electromagnetic magnetic lock. The power cord of the retraction lock is connected to the automatic power switch and the manual remote control switch. When energized, the lock tongue retracts. When unlocked and powered off, the latch pops out and locks, the airbag cushion base is fixed under the airbag, and is symmetrically paired with the fixing strap on the airbag cushion. At each end of the airbag cushion base, there is an airbag cushion retractable lock, which is symmetrically paired with the retractable locks at both ends of the fixing strap on the airbag cushion and locked on the latch of the retractable lock. The high-pressure air pipe connector on the airbag cushion is connected to the air pump via the high-pressure air pipe, and the vacuum air pipe connector is connected to the vacuum pump via the vacuum air pipe. When the flood sensor automatically switches on and detects an impending flood, it automatically turns on the power switch. When the power switch is turned on manually or by remote control, the airbag retractable lock is powered on, the latch retracts and unlocks, the air pump is powered on and begins to inflate, inflating the airbag cushion through the high-pressure air pipe. The car is then floated on the water, avoiding flooding, and can be driven on the water to escape danger and survive.After the flood recedes, turn on the manual or remote switch of the vacuum pump to connect the power supply. The vacuum pump, through the vacuum tube connected to the airbag cushion, extracts the air from the airbag cushion, causing the airbag cushion to contract, the airbag cushion support to contract and move upward, and the airbag cushion retraction locks at both ends to lock onto the latches of the airbag cushion retraction lock. The top-mounted flood control airbag cushion is cylindrical, with two parts, left and right, connected to the front and rear horizontal fixing rods, vertical fixing rods, fixing clamps, and mechanical arm. It is fixed to the top of the vehicle using the base plates of the front and rear horizontal fixing rods and the base plate of the mechanical arm. The upper and lower fixing clamps of the top-mounted airbag cushion are fixed to the upper and lower parts of the airbag cushion, and the upper part of the upper fixing clamp is fixed to the upper part of the airbag cushion. The air passage of the airbag cushion is connected to the air valve of the vertical fixed rod via a high-pressure air pipe at the bottom of the front and rear vertical fixed rods. The vertical fixed rods are multi-section cylinder telescopic type, with four sections at the front, rear, left, and right, each equipped with a lifting clip. The horizontal fixed rods are also multi-section cylinder telescopic type, one at the front and one at the rear. The upper ends of the vertical fixed rods are fixed to the ends of the horizontal fixed rods and the robotic arm using connecting locking pins, flat washers, open locking pins, and T-shaped shafts. The air inlet and outlet ports of the vertical fixed rod cylinders are connected to the air valves of the horizontal fixed rods via high-pressure air pipes, and the timing of air inlet and outlet is controlled by the horizontal fixed rod cylinders, while the timing of lifting clip rotation is controlled by the robotic arm. The bottom of the fixed rod, carrying the lifting clip, rotating clip shaft, and locking ring, is fixed to the top of the airbag cushion. The upper part is connected to the crossbar and locked with a locking pin. It can rotate left and right under the control of the robotic arm on the airbag cushion fixing clamp and the crossbar joint. The top of the vertical fixed rod is equipped with a lifting clip crank arm and a lifting clip lever. The lifting clip crank arm is connected to the robotic arm via a T-shaped shaft. The T-shaped shaft's side end connects to the crank arm, and the double shaft ends connect to the robotic arm, allowing simultaneous up-down, forward-backward, and backward rotation. The lifting clip lever extends downward into the outer stop of the lower part of the vertical fixed rod, directionally rotating the lifting clip to the outer frame of the vehicle's floor. The robotic arm is a cylinder-type telescopic arm, with two units each for the front, rear, left, and right sides, fixed to the roof with a base plate. The robotic arm has a mounting plate on its base plate... The horizontal bar has a sliding track when it extends. When the horizontal bar is fully extended and exposes the air intake valve of the vertical bar and the robotic arm, the vertical bar and the robotic arm extend simultaneously with air intake. When the vertical bar extends to the lower stop point, the robotic arm pushes the crank arm to rotate the toggle lever to rotate the toggle to the bottom of the car and support the car's undercarriage frame. The vertical bar air valve inflates the airbag cushion through the high-pressure air pipe and the airbag air valve, and the car is lifted. The driver can drive away from the danger and escape during the journey. When the flood recedes, the manual switch or remote control switch can be pressed to turn on the vacuum pump power, drain the air from the airbag cushion, and the vertical bar and the robotic arm retract simultaneously and rotate back to the lifting card. The horizontal bar retracts last and pulls the vertical bar and the airbag cushion back to the roof of the car.
