Polyhedron 14 is made using high strength steel or high strength ceramics material, and the surface of polyhedron 14 is set as coarse face, to increase
Combination frictional force between strong, can jail due to the biggish frictional force in their surfaces after multiple polyhedrons are stitched together
Solid link together, and avoid that the changing of the relative positions occurs when by power perpendicular to car door, polyhedron is after splicing is completed, two sides
Face is respectively provided with cover board, can further enhance the holistic resistant behavior for the car door that polyhedron is combined into this way.Polyhedron 14 is small
Particle, its side length is 0.1~0.3mm, under this size, it is ensured that effect of these molecules in high frequency sound wave
Under, the frictional resistance at interface is overcome, and then molecule and its interface moment is caused to be made entire car door damaged by explosion.5th
Power supply 24 is that sonic generator and controller 13 provide power supply；
As shown in figure 3, it is 1400MPa~2000MPa that the material of the first cover board 22 and the second cover board 23, which is preferably intensity,
The ceramic material that steel or intensity are 1000MPa~1500MPa, thickness is preferably 0.05mm~0.1mm, equally can be in sound wave effect
Lower moment is by explosion；And entire car door scale is enough to ensure basic mechanical performance (intensity, toughness and shock resistance), two layers
After the completion of plate or ceramic coating construction, car door superficial layer is processed by shot blasting.

When preset watermark threshold (0.4~0.5m), the first image processing module 4 sends pre-warning signal to controller 13.
Second source 5 is that second camera 6 provides power supply；Second camera 6 takes pictures to the front row of car 1, so
It will take a picture afterwards and be sent to the second image processing module 7；The photo that second image processing module 7 shoots second camera 6
It is handled, using image algorithm, then judges that 1 front row of car is transmitted to control by conducting wire either with or without people, and by result
Device 13.Meanwhile the height of water level outside front door is judged using image algorithm, when the value is more than in the second image processing module 7
When preset watermark threshold (0.4~0.5m), the second image processing module 7 sends pre-warning signal to controller 13.
(2) the pressure prior-warning device on car door
Pressure sensor 11 is provided in front door and rear door, it can supervise the pressure being subject on car door
It surveys, and the value measured is transmitted to data processing module 12；The pressure that 12 calculation pressure sensor 11 of data processing module is subject to is big
It is small, when the value is more than preset threshold pressure (2700~3000N/m2) in data processing module 12, data processing
Module 12 sends pre-warning signal to controller 13.Pressure sensor 11 is made by piezoceramic material.
(3) vehicle interior temperature prior-warning device
The top that vehicle is arranged in temperature sensor 8 is leaned on into car door side, it can measure interior temperature, and will
The temperature value measured passes to temperature monitoring module 9 by conducting wire, when the value is more than the preset temperature in temperature monitoring module 9
When spending threshold value (50~60 DEG C), temperature monitoring module 9 sends pre-warning signal to controller 13.
(4) car CO concentration prior-warning device
CO measurement of concetration module 19 is arranged in below the front stall and back seat of vehicle, it can survey interior CO concentration
Amount, and the value measured is transmitted to CO concentration monitor module 21, when the value is more than preset in CO concentration monitor module 21
When concentration threshold (170~200mg/m3), CO concentration monitor module 21 sends pre-warning signal to controller 13.
The information that controller 13 is likely to be received is following 5 kinds:
(1) first image processing module 4 or the second image processing module 7 judge car for the result of someone；
(2) first image processing modules 4 or the pre-warning signal of the second image processing module 7 transmitting；
(3) pre-warning signal that data processing module 12 emits；
(4) pre-warning signal that temperature monitoring module 9 emits；
(5) pre-warning signal that CO concentration monitor module 21 emits；
When controller 13 receives any one of (1) and (2)~(5), control switch 17 is opened, and makes the first sound wave
Generator 27, the second sonic generator 28, third sonic generator 29, falling tone wave producer 30, fifth sound wave producer 31
Start simultaneously at work.First sonic generator 27, the second sonic generator 28, third sonic generator 29 can carry out car door
Instantaneous directional blasting.Falling tone wave producer 30 and fifth sound wave producer 31 can carry out instantaneous directional blasting to vehicle window.
The calculating of present invention transmitting sound wave energy-flux density and frequency is explained below；
We first establish the sound wave of pinger transmitting energy-flux density and the thickness of car door, average each particle and its
The quantitative relationship of the coefficient of friction of the faying face number and particle surface of neighboring particles；Then, it calculates and finds out car door in given item
(thickness of car door, average each particle and the faying face number of its neighboring particles and the coefficient of friction of particle surface) explosion under part
Facet level needs the energy applied；Due to the sum of the thickness with a thickness of facet level and two layers of cover board of the car door in calculating,
Therefore consider influence of two layers of cover board to energy balane；So the energy being finally calculated is enough to facet level and two layers
Cover board carries out explosion.After knowing the energy that needs apply, we are become using acoustic wave energy and sonic wave amplitude, frequency and velocity of wave etc.
The quantitative relationship of amount just finds out the frequency that pinger needs to issue sound wave.
First sonic generator 27, the second sonic generator 28, third sonic generator 29,30 and of falling tone wave producer
Fifth sound wave producer 31, this five pingers transmitting sound wave be instantaneous high frequency sound wave, frequency range be 10~
20kHz；The energy-flux density E of the sound wave of first pinger, the second pinger and the transmitting of third pinger, can be with
Overcome the frictional resistance combined between molecule interface, makes particle and its interface moment by explosion；The size of the energy-flux density E of sound wave
According to following three indexs:
(1) thickness (thickness including facet level and two layers of cover board) of car door；
(2) the faying face number of average each particle and its neighboring particles；
(3) coefficient of friction of particle surface；
Specific calculation formula are as follows:
E=kdn2μ
Wherein, k is constant, and value is 1.0 × 109, d is the thickness of car door, and polyhedral face number described in n, μ is described more
The coefficient of friction in face body surface face.
Such as car door is with a thickness of 5cm；When polyhedron 14 is using regular hexagonal prism, average each particle and its neighboring particles
Faying face number is 6；Polyhedral Particles use high strength steel, and surface is coarse face, its coefficient of friction is 0.6；
It can then make molecule and its interface moment by the energy flux density of explosion
E=kdn2μ=1 × 109×5×62× 0.6=1.08 × 1011
Assuming that the amplitude of the sound wave of sonic generator transmitting immobilizes for 5mm；The density of steel is 7850kg/m3；Sound
Propagation density of the wave in steel is 5200m/s；The tranmitting frequency of sound wave can then be found out.
Because the energy-flux density calculation formula of sound wave is
Wherein, P is Media density, and ω is frequency of sound wave, and A is amplitude, and u is velocity of wave.
The value of the energy stream of needs is brought at this time, the frequency of sound wave that can be used in the hope of needs are as follows:
The frequency that 4th kind of pinger and the sound wave of the 5th kind of pinger transmitting specifically use is according to vehicle window glass
The thickness of glass is determined；Thickness is less than 3mm, frequency 10kHz；When with a thickness of 5mm, frequency 20kHz；Thickness is between 3mm
When to 5mm, linear difference.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
