Decorative panel is bigger than mounting groove and is fixed on outside mounting groove, and installation groove edge is equipped with jack, and decorative panel is towards the side of bumper one side
Edge is equipped with rubber insert with the enjoyable cooperation of jack, when such air bag receiving state, does not interfere with the beauty of vehicle, decorative panel
Plastic plate can be used, there is certain elasticity, slight impact will not damage, and also be convenient for changing even if having hit damaged.
As shown in Figure 1, being equipped with mounting rack 1 in ejection air bag 2, the inner wall of ejection air bag 2 is fixed on mounting rack 1, is installed
Frame 1 is made of fore-stock and after-poppet, and fore-stock and after-poppet are that simultaneously lateral arrangement (is two strip structures separated with automobile
Reference substance), elastomeric element is connected between fore-stock and after-poppet, elastomeric element has equidistantly been longitudinally arranged 2-5, elastic portion
Part is spring or hydraulic damper 3, and hydraulic damper 3 is not as shown in figure 3, elastomeric element can be between fore-stock and after-poppet
Under starting ejection 2 state of air bag, slight impact occurs moving Che Shiruo, elastomeric element can have certain supporting role, energy
Enough damages for reducing slight impact when moving vehicle reduce what gas in ejection air bag 2 generated when launching the inflation starting of air bag 2
Speed to not only increase the reaction sensitivity and protecting effect of the covering device, and is effectively prevented because of air bag pop-up
Dynamics is to the injury caused by car body itself.
It launches air bag 2 and is equipped with air inlet and be equipped with a threeway, also be provided with a threeway at the port of high pressure gas holder 7, two
Threeway passes through admission line 4 respectively and is connected to return-air air flue, and wherein admission line 4 is equipped with the first solenoid valve, on return-air duct
Equipped with second solenoid valve and air pump, launching bypass on the return-air duct between air bag 2 and air pump has the bypass pipe for being connected to the external world, other
Siphunculus is equipped with third solenoid valve, and first pressure sensor is equipped in ejection air bag 2, second pressure is equipped in high pressure gas holder 7 and passes
Sensor, first pressure sensor and second pressure sensor output signal to electronic control unit 6, and electronic control unit 6 exports
Alarm signal to interior alarm, while 6 output drive signal of electronic control unit to the first solenoid valve, second solenoid valve,
Third solenoid valve and air pump coordinate the intelligentized work of whole device.
The solar battery that electronic control unit 6 is equipped with by independent lithium battery power supply, automobile external as lithium battery charging
Plate 8, front bumper and/or rear bumper are equipped with range sensor 5, and range sensor 5 outputs signal to electronic controller list
Member, electronic control unit 6 connect vehicular meter and obtain speed signal.
Control method based on the anti-error collision device of above-mentioned automobile:
1) when running car, device starting；

Setting value closes the second battery valve and air pump.
Furthermore device can detect high pressure gas holder 7 when automatic inflating device, i.e. step 1) device starting in 7 deficency of high pressure gas holder
Interior air pressure opens second solenoid valve and third solenoid valve and booster air pump is pumped into high pressure gas holder 7 if being lower than setting value
Air closes second solenoid valve and third solenoid valve and air pump until pressure reaches setting value in high pressure gas holder 7；
In the device course of work, air pressure in step 2) real-time detection high pressure gas holder 7, if air pressure drop low velocity is greater than setting
Value, then alarm, and indicates that device gas circuit is problematic, needs to overhaul.
Use the present invention, the absorption of the ejection and gas of launching air bag 2 all intelligent operations, since its gas is not
The mode of after chemical reaction generates, therefore can reuptake to the gas for pouring air bag, and the gas of absorption can be another
It is secondary to be inflated work, to ensure that the device can be recycled for multiple times, greatly reduce use cost.Using dual range
Sensor 5, which persistently receives distance signal and electronic control unit 6 instead of wheel speed sensors, can realize the multi-scale analysis of signal
Accurately judges and execute protection act.In addition, the main source of energy of the electric power source of the covering device is provided by double solar panels 8,
Without in-vehicle secondary battery power supply is not required to substantially in special circumstances, to save in automobile inherently limited electric power energy.In air bag
Inside is equipped with hydraulic damper 3, the shock dynamics absorbed by air bag has both been shared significantly, but also the set protective device is to air bag
The speed and aeration quantity of pop-up require to reduce, so that the safety to automobile itself will not reach into injury.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
