The specific embodiment
Further describe the utility model below in conjunction with instantiation and accompanying drawing, but this example is not limited to the utility model, every employing the utility model analog structure and similar variation thereof all should be listed protection domain of the present utility model in.Control air-bag deployment such as the utility model with controller, also can be designed to directly control air-bag deployment with sensor.The applicant has designed a 12 meters full-bearing type highway passenger vehicle CAE realistic models of this device that are equipped with as specific embodiment according to the utility model.
The utility model adopts rollover inclination angle and two groups of signals of the pre-contact distance of vehicle body collision, the expansion of the external air bag of step control passenger vehicle.This protective device is by a controller, obliquity sensor, some vehicle bodies collision pre-contact rang sensor and be installed in the bus roof outer both sides and the external protection safety air bag at waist rail position consists of.Climb over the in good time air-bag deployment that triggers of grouping in the journey at passenger car side, climb over the energy that in journey produce with as far as possible passenger car sides that absorb more, reduce simultaneously the collision momentum on vehicle body and ground, realize the more effective protection of occupant in the main cabin.Because quite a few energy that passenger car side climbs in the journey is taken away by the gas that the protection safety air bag discharges, and has largely reduced the side overturning crash requirement of strength to Bus Frame, for the car load light-weight design provides greater room.
As shown in Figure 4, controller 1 and obliquity sensor 2 are fixed near the car load center of gravity, on the steel plate 4 of floor level below 3.
As shown in Figure 5, contact in advance rang sensor (I, II, III, IV, V, VI) 6,7,8,9,10,11 with 1 one-tenth of controller and connect relation.Set each pre-contact rang sensor threshold value, control respectively safety air bag (I, II, III, IV, V, VI) 12,13,14,15,16,17 and launch constantly, lose heart immediately after launching to contact to earth.Need in the process of losing heart to set the threshold value of losing heart according to car body self structure and Load Characteristics, so that safety air bag keeps suitable constant air pressure, reach the buffer protection effect.Each safety air bag lose heart finish after, passenger vehicle most of energy of turning on one's side has been converted into gas kinetic energy and has been released in the atmosphere, residual amount of energy is then by body framing self plastic deformation and material self inner structure Damping work, the realization side-tipping protective.Each safety air bag group organize work effect such as Fig. 6.
Shown in Fig. 7 A, top cover rang sensor 7II is the ultrasonic distance sensor, is installed in bus roof outer air flue 18 inside, and sensor probe stretches out coach skin 19 surfaces.Shown in Fig. 7 B, waist rail position sensor 10 is ultrasonic transduter, is installed in 20 following boot compartment, 21 inside, floor, and sensor probe stretches out the coach skin surface.All the other rang sensor structures are similar, and principle is identical.Shown in Fig. 8 A, top cover safety air bag II13 is installed in bus roof outer air flue 18 inside, is supported fixing by baffle plate 22I.Safety air bag is comprised of airbag I23 and gas generator I24, places in the sheet plastic I25, breaks through thin plate I25 during expansion and ejects.Shown in Fig. 8 B, waist rail position safety air bag V16 is installed in 20 following boot compartment, 21 inside, floor, is supported fixing by baffle plate II30.Safety air bag V16 is comprised of airbag II28 and gas generator II31, places in the sheet plastic II29, breaks through thin plate II29 during expansion and ejects.As shown in Figure 9, in the safety air bag working process, constant voltage aie escape valve device 33 place and launch after mode of operation air bag 32 outsides, be arranged symmetrically with before and after being.By the disappointing threshold value of design aie escape valve level pressure, the external air bag rollover of realization different automobile types protection Optimum Matching.
The utility model is achieved through the following technical solutions:
1 when passenger vehicle begins to turn on one's side, and system enters A job step among Fig. 1, by being installed on the obliquity sensor of passenger vehicle inside, detects the lasting change amount of non-transient state that passenger car side climbs over car body angle in the journey
Dip angle signal is sent into controller.
2 follow system enters B job step among Fig. 1, and controller climbs over the lasting change amount of the non-transient state of car body angle in the journey by ECU unit, offside
Identification judges whether to surpass the rollover threshold value
3 work as controller determines
The time, enter C job step among Fig. 1, trigger immediately the work of the pre-contact of each vehicle body collision rang sensor.
4 then, and each contacts in advance rang sensor and will survey electric signal and return B job step middle controller, by controller to each sensor distance ground distance signal h
iIdentify judgement, judge whether less than gas generator activation threshold value h
0
5 when confirming h

0The time, namely enter D job step among Fig. 1, control respectively corresponding air-cushion inflator triggering for generating miscellaneous gas by controller.The miscellaneous gas that each gas generator produces successively is filled with the airbag of difformity, different size, diverse location, and all gas replenishment process was finished before the safety air bag kiss the earth.
6 when safety air bag begins kiss the earth, and whole system namely enters E job step among Fig. 1.According to body framing deformation characteristic in the rollover process, each safety air bag priority kiss the earth also keeps level pressure to lose heart, and the absorption of finishing most energy in the rollover process transforms.
7 carry out the job step F of Fig. 1 at last, and at the disappointing complete aftercarriage skeleton kiss the earth of safety air bag, passenger vehicle rollover residual amount of energy is absorbed by body framing self plastic deformation.Pass through control safety air bag activation time, charge air in the whole rollover process.Inside air bag pressure and the speed of losing heart are controlled at a suitable numerical value by the pressure valve that is installed on the dress airbag, and assurance Bus Frame, glass, safety air bag etc. are not all invaded passenger's living space.
