Referring to fig. 7, the right edge of the upper surface of the left ceiling plate 8 and the left edge of the upper surface of the right ceiling plate 7 are provided with a plurality of delay triggering columns 9. The delay triggering column 9 comprises a triggering column outer cylinder 26, a triggering column inner cylinder 25 and a spring 24, the triggering column outer cylinder 26 is fixedly connected with the ceiling left plate 8 or the ceiling right plate 7, the top opening of the triggering column outer cylinder 26 is retracted, the bottom edge of the triggering column inner cylinder 25 is provided with an outer flange, the triggering column outer cylinder 26 is clamped outside the triggering column inner cylinder 25, and the triggering column inner cylinder 25 forms the telescopic end of the delay triggering column 9. The spring 24 is arranged in the trigger column inner cylinder 25, the top of the spring 24 is fixedly connected with the inner wall of the top of the trigger column inner cylinder 25, and the bottom of the spring 24 is fixedly connected with the ceiling left plate 8 or the ceiling right plate 7. And a second acceleration sensor 23 for sensing the acceleration in the vertical direction is arranged on the top of the trigger column inner cylinder 25. The first acceleration sensor 22 and the second acceleration sensor 23 are both connected with the controller ECU21 to send acceleration information to the controller ECU21, and the controller ECU21 is used for controlling the expansion and contraction of the pneumatic expansion and contraction assembly 10 according to the acceleration information, specifically, indirectly controlling the expansion and contraction assembly through the high-pressure air storage tank 18 and the air compressor 19. An outlet of the high-pressure air storage tank 18 is connected with an air inlet of the pneumatic telescopic assembly 10 through a starting air valve 17, an air outlet of the pneumatic telescopic assembly 10 is connected with an air discharging return valve 16, an outlet of the air compressor 19 is connected with an air inlet of the high-pressure air storage tank 18 through an air charging valve 20, and the controller ECU21 is connected with the air compressor 19, the starting air valve 17, the air discharging return valve 16 and the air charging valve 20.
The working process of the device for preventing the falling object from smashing the automobile roof is that when the falling object smashes the automobile roof, the first acceleration sensor 22 or the second acceleration sensor 23 sends sensed vertical impact acceleration signals to the controller ECU 21. The controller ECU21 commands the starting air valve 17 to open, high-pressure air stored in the high-pressure air storage tank 18 enters the pneumatic telescopic assembly 10 through the starting air valve 17, the air pressure in the pneumatic telescopic assembly 10 increases suddenly, the piston rod 14 rises rapidly, the left return tension spring 11a and the right return tension spring 11b extend, the roof right plate 7 moves in a plane by taking the roof right hinge 15a and the two right slider hinges 5 as constraints, the roof left plate 8 moves in a plane by taking the roof left hinge 15b and the two left slider hinges 6 as constraints, the roof right plate 7 and the roof left plate 8 are in an inclined jacking state, and then the starting air valve 17 is closed. The inclined postures of the roof right plate 7 and the roof left plate 8 can induce falling objects to roll away towards the left side and the right side of the roof of the automobile, so that the roof is lightened or completely prevented from being crashed.
When falling objects fall towards the middle area of the roof, the falling objects firstly trigger the second acceleration sensor 23 of the delay triggering column 9, the controller ECU21 sends an opening command to the starting air valve 17 to cause the roof to rise, and when the falling objects touch the outer cylinder 26 of the triggering column or the plate surface in the middle of the roof, the roof is already in an inclined state, so that the falling objects can roll away towards the left and right directions of the roof. When the falling object falls toward the area outside the roof, on the one hand, the roof will rise and tilt after the first acceleration sensor 22 gives a command to the controller ECU 21; on the other hand, the roof supporting points formed by the two left sliding block hinges 6 and the roof left hinges 15b or the two right sliding block hinges 5 and the roof right hinges 15a are all positioned at the inner side of the roof, and the seesaw effect also causes the roof to incline and the falling objects to roll away from the roof in the left-right direction.
After the induction of falling objects is completed and the safety of the roof is confirmed, a driver clicks a reset button 27 to instruct the controller ECU21 to send an opening signal to the deflation return valve 16, the deflation return valve 16 is opened, at the moment, high-pressure gas in the trigger cylinder assembly 10 is discharged through the deflation return valve 16, under the action of the tensile force of the left return tension spring 11a or the right return tension spring 11b, the piston rod 14 descends and resets, then the deflation return valve 16 is closed, and the roofs on the left side and the right side are in a retracted state, so that the driving wind resistance is reduced. The controller ECU21 commands the charge valve 20 to open, commanding the air compressor 19 to begin compressing air. When the air pressure in the high pressure air tank 18 reaches a predetermined value, the controller ECU21 commands the air compressor 19 to stop compressing air, and then closes the charge valve 20. The high pressure air in the high pressure air tank 18 is used as the power source for the roof to be lifted when the roof is impacted by the falling object next time.
