Description
Technical field
The present invention relates to a kind of anti-explosion air-sac device.
Background technology
At present, the passenger vehicle on market is mounted air suspension substantially, and the airbag safety on its air suspension is directly connected to the driving safety of car load.Passenger vehicle when high-speed cruising, during the unexpected explosion of air bag, the gas in air bag can disperse rapidly, now air bag upper cover plate can under the effect of vehicle weight dramatic decrease, eventually fall on air bag lower cushion block.Passenger vehicle is frequently with two air bags of forward mounting (each one of limit, left and right); four air bags of rear-mounted (each two marked prices in limit, left and right); when one of them air bag of passenger vehicle or monolateral air bag explosion; because of air bag dramatic decrease; vehicle body can tilt suddenly; vehicle's center of gravity changes, and the vehicle at high-speed cruising often can cause turning to and brake failure, thus causes the generation of vehicle accident.Simultaneously again due to Unpredictability and the uncontrollability of air bag explosion, thus frequently result in the generation of vehicle accident.
Summary of the invention
It is an object of the invention to provide a kind of anti-explosion air-sac device, this device can avoid vehicle's center of gravity to change suddenly, turn to and brake the most malfunctioning phenomenon in air bag explosion moment.
For achieving the above object, present invention employs techniques below scheme: before including being separately positioned on, air bag in rear suspension, described air bag includes airbag body, the top of described airbag body is provided with air bag upper cover plate, air bag upper cover plate is provided with baroceptor and inlet suction port, the probe of described baroceptor stretches in airbag body, the bottom of airbag body is connected with air-bag base by air bag lower cushion block, the bottom surface of described air bag upper cover plate is to having cushion block on air bag, on described air bag, the elastic device of both connections it is provided with between lower cushion block, described baroceptor is connected with the input of ECU processor, the outfan of ECU processor is connected with low-pressure warning device.
Described elastic device includes the spring that vertical is arranged, described spring be respectively arranged at two ends with the threaded rod that cushion block upper and lower with air bag is connected.
On described air bag, cushion block is weldingly connected with air bag upper cover plate, and described air bag lower cushion block is weldingly connected with air-bag base, and the upper and lower cushion block of air bag is respectively equipped with the screwed hole that the threaded rod with both ends of the spring matches.
Described low-pressure warning device is arranged in instrument desk of passenger car.
Arranging two air bags on described front suspension, described rear suspension arranges four air bags, described low-pressure warning device arranges six.
As shown from the above technical solution, the present invention is by arranging spring between the upper and lower cushion block of air bag, the moment of air bag explosion, under the action of the spring, air bag upper cover plate can slowly decline, vehicle body can slowly tilt, at this moment the change of air pressure in baroceptor senses air bag, signal is fed back to ECU processor, ECU controller feeds back to low-pressure warning device, according to low-pressure warning device, driver can judge which air bag occurs in that explosion, thus car load is carried out emergency processing, it is to avoid the generation of vehicle accident.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of elastic device of the present invention；
Fig. 3 is the schematic diagram of the present invention.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings:
Such as Fig. 1, a kind of anti-explosion air-sac device shown in Fig. 3, before being separately positioned on, air bag 1 in rear suspension, air bag 1 includes airbag body 2, the top of airbag body 2 is provided with air bag upper cover plate 21, air bag upper cover plate 21 is provided with baroceptor 3 and inlet suction port 4, the probe of baroceptor 3 stretches in airbag body 2, the bottom of airbag body 2 is connected with air-bag base 23 by air bag lower cushion block 22, the bottom surface of air bag upper cover plate 21 is to having cushion block 24 on air bag, on air bag, lower cushion block 24, the elastic device of both connections it is provided with between 22, baroceptor 3 is connected with the input of ECU processor 6, the outfan of ECU processor 6 is connected with low-pressure warning device 7.
Further, as in figure 2 it is shown, elastic device includes the spring 5 that vertical is arranged, spring 5 be respectively arranged at two ends with the threaded rod 51 that cushion block 24,22 upper and lower with air bag is connected.
Further, on air bag, cushion block 24 is weldingly connected with air bag upper cover plate 21, and air bag lower cushion block 22 is weldingly connected with air-bag base 23, and the upper and lower cushion block of air bag 24,22 is respectively equipped with the screwed hole that the threaded rod 51 with spring 5 two ends matches.
Further, low-pressure warning device is arranged in instrument desk of passenger car, it is preferred that low-pressure warning device should be arranged on the position that on instrument desk, driver it is readily seen that.
Further, front suspension arranging two air bags, rear suspension arranges four air bags, low-pressure warning device 7 arranges six.Namely arranging altogether six air bags on fore suspension and rear suspension, respectively by wire harness with ECU processor even, ECU processor is connected six air bags again with six low-pressure warning devices, i.e. one the corresponding low-pressure warning device of air bag.
The operation principle of the present invention is as follows:
As shown in Figure 3, four air bags 1 on rear-mounted are connected to ECU processor 6 by wire harness respectively with two air bags 1 in forward mounting, ECU processor 67 devices of being reported to the police with six low pressure respectively by linear speed are connected, when there is moment explosion in air bag 1, gas in air bag 1 is by pop-off, now air bag upper cover plate can decline downwards under the effect of complete vehicle weight, because of between the upper and lower cushion block of air bag equipped with spring, air bag upper cover plate can slowly decline under the action of the spring, air bag can slowly reduce, vehicle body can slowly tilt, and vehicle's center of gravity is by slowly varying；Meanwhile, this signal can be passed to ECU processor and be analyzed processing by the baroceptor on air bag, ECU processor feeds back to low-pressure warning device again, at this moment low-pressure warning device can be shown in red, it is simultaneously emitted by roar and reminds driver, according to the sequence number of air pressure alarm, driver can judge which air bag occurs in that explosion, thus car load carries out emergency processing, such as adjust turn to, pulling over observing etc.；Spring in air bag, not only avoid vehicle and tilts suddenly, also won the quality time of emergency processing for driver, it is to avoid the generation of vehicle accident.
Embodiment described above is only to be described the preferred embodiment of the present invention; not the scope of the present invention is defined; on the premise of designing spirit without departing from the present invention; various deformation that technical scheme is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that claims of the present invention determines.
