The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail, as shown in Figures 1 and 2: automotive anti-rolling emergency support inflatable pneumatic bag backing device of the present invention and method, be provided with and be not subjected to shake, jolt and collide restriction, the roller sensor 1 that detects and roll only, described inclination roller sensor 1 is provided with 360 degree insulator tubular cavities 95 in sensor outer housing 93.At 360 degree insulator tubular cavities, 95 lower parts the conductor mercury that flows is housed, be provided with the horizontal mercury of the mobile buffering of mercury next door 97 at 360 degree insulator tubular cavities, 95 lower parts, it is mobile that mercury laterally is obstructed, and makes the mercury wall not soak into cavity wall increase buffering mercury inertia flow and move.Be respectively equipped with 2 mercury sink-float pipes 94 at 360 degree insulator tubular cavities, 95 first half two ends.When inclination of vehicle, mercury plane 98 1 ends rise mercury sink-float pipe 94 are floated, the other end mercury sink-float pipe 94 mercury next doors 97 that are provided with are blocked mercury sink-float pipe 94 and are not being descended, making mercury do not shaken by the resistance increase of mercury sink-float pipe 94 rises the mercury plane after the restriction of jolting and colliding has only inclination continuously, float mercury sink-float pipe 94 or open the plane mercury contact 104 that 360 degree insulator tubular cavities, 95 inwalls are provided with in case of necessity and contact, thereby achieve the goal with conductor mercury.The bigger insulating material of the mercury sink-float pipe wear-resisting proportion of 94 usefulness is made, and slides freely in 360 degree insulator tubular cavities 95, and mercury is not entered between the inwall of mercury sink-float pipe 94 outer walls and 360 degree insulator tubular cavities 95.The overall diameter of 360 degree insulator tubular cavities 95 does not exceed 10 centimetres, in the cavity directly through being 6 * 6 millimeters, mercury flow cavity 103 interior diameters of mercury sink-float pipe 94 are 3 * 3 millimeters, be respectively equipped with 7 contacts 104 at 360 degree insulator tubular cavities, 95 semicircle first half inwalls, and connect with lead-in wire respectively and draw outside the 360 degree insulative tubular cavitys 95 and outside the sensor outer housing 93, when inclination of vehicle and when rolling the mercury in the roller sensor 1 along tilting and the direction of rolling rises and the mercury sink-float is managed 94 floats, tilt to reach 30 degree roller sensor power connection lead-in wires 102 and roller sensor 1 and connect 101 conductings of language prompting lead-in wire, the alerting degree of dip can be established in voice, support such as is about to open at voice.This function can be done the usefulness that vehicle is paddled and go slowly in the slope, as exercise vehicle tilt and reach mercury adipping in the 40 degree roller sensors 1 and rise roller sensor power connection lead-in wire 102 and turn over sensor and connect gas generator 100 conductings that go between, main support 2, assistant support 5 are opened successively or air bag liner 117 is opened and achieved the goal.Form serious accident as vehicle and cause the sink-float mercury flow cavity 103 of rolling by being provided with, mercury with mercury sink-float pipe 94 floating to card 96 backs that put in place, mercury flow in the mercury flow cavity 103 float pipe put in place the roller sensor power connection of card 96 tops go between 102 and 100 conductings that go between of the contact internal heat body producer of opposite side the main support 2 in the opposite side threshold vehicle cavity 4, assistant support 5 can be opened successively.Make the car gage lengthening prevent vehicle to roll continuously, thereby reach the vehicle supporting role, particularly run into when growing up gradient road surface and can reduce the loss.Fig. 1 and shown in Figure 3 is provided with two carrier bases 3 in automobile door sill cavity 4, carrier base 3 is provided with the floor and connects pawl 35, and the car door post
