As indicated at 3, which includes the first sensing device 11, controller 12, air charging system 13 and air bag sheet
Body 14, for the first sensing device 11 for detecting whether automobile collides, airbag body 14 generally remains retracted state, and is filling
Can be expanded after gas, air charging system 13 is used to make airbag body 14 expand to the inflation of airbag body 14, the first sensing device 11 with
Controller 12 is electrically connected, and controller 12 and air charging system 13 are electrically connected, and air charging system 13 is connect with airbag body 14, and first
The signal that sensing device 11 will test is sent to controller 12, and controller 12 receives the letter that the first sensing device 11 detects
Breath, and make a decision, then controller 12 sends signal to air charging system 13, fills to control air charging system 13 to airbag body 14
Gas or controller 12 do not send signal to air charging system 13, so that airbag body 14 remains retracted state.
In the present embodiment, the first sensing device 11 is acceleration transducer, for detecting the reality in vehicle traveling process
Acceleration value is set with the threshold value of the acceleration in vehicle traveling process in controller 12, when the first sensing device 11 detects
Actual acceleration value be more than or equal to the threshold value when, i.e., expression automobile will crash, controller 12 i.e. issue signal
To air charging system 13, air charging system 13 starts to be inflated to airbag body 14, so that airbag body 14 be made to expand, it is anti-to form safety
Shield.Work as automobile normal running, i.e. the actual acceleration value in vehicle traveling process that the first sensing device 11 detects is less than threshold
When value, controller 12 does not send signal to air charging system 13, and air charging system 13 stops working, and airbag body 14 is in the shape shunk
State.
In the present embodiment, air charging system 13 uses gas generator, which has outlet side, airbag body 14
With inlet end, outlet side and inlet end are connected by connecting tube 15.
The airing form that gas generator is inflated to airbag body 14 is explosion inflation or cold air inflation, or is filled for explosion
The combination of gas and cold air inflation.Specifically, gas generator include tube body, the igniter being arranged in tube body, gunpowder and/or
Gas-forming agent, controller 12 and igniter are electrically connected, and igniter is for the gunpowder that ignites.Explosion inflation is directed to air bag
The gas that ontology 14 is inflated is gas caused by gunpowder explosion, and the gas that cold air inflation is directed to the inflation of airbag body 14 is gas
Gas caused by body propellant, explosion inflation are directed to the gas of the inflation of airbag body 14 with the airing form of cold air inflation combination
Body includes simultaneously gas caused by gas and gas-forming agent caused by gunpowder explosion.When by the way of cold air inflation
When, it can avoid gas caused by gunpowder explosion and environment damaged and polluted to occupant 300.Comprehensively consider, generally using quick-fried
The airing form of inflation with cold air inflation combination is fried, also uses this airing form in the present embodiment.It can make airbag body in this way
14 expansion rapidly in a very short period of time, form elastic air cushion in the front of occupant 300, impact energy are absorbed, thus effectively
Occupant 300 is protected, injury is made it from or mitigates extent of injury.
The air bag module 1 further includes power supply device 16, power supply device 16 respectively with the first sensing device 11 and control
Device 12 is electrically connected, and power supply device 16 is used to power to the first sensing device 11 and controller 12.In the present embodiment, the first sensing
Device 11 and controller 12 can also be powered by the generator and battery of automobile itself simultaneously, but due to automobile itself
Generator and usually easily damaged all in the headstock position of battery, therefore, the power supply device 16 in the present embodiment can ensure that peace
The performance of the effect of full air bag module 1.
The air bag module 1 further includes shell, the first above-mentioned sensing device 11, controller 12, air charging system 13, gas
Capsule ontology 14, connecting tube 15 and power supply device 16 it is integrally disposed in the housing, shell is removably disposed in automotive seat
The back side of backrest 101, so that it is whole clean and tidy when the air bag module 1 is installed on automotive seat, beautiful, and install and
Convenient disassembly, and when automobile collides, airbag body 14 is expanded and can be popped up rapidly out of shell after inflating, thus to occupant
Carry out security protection.
The invention also discloses a kind of child safety seat, which includes seat body 400 and such as
Above-mentioned air bag module 1, the child safety seat is in use, seat body 400 is mounted on the back seat 200 of automobile
On, automobile has the front-row seats 100 in the front for the back seat 200 for being located at setting seat body 400, air bag module
1 is removably disposed in the top at the back side of the backrest of the front-row seats 100, thus when automobile collides, to resting on
The head of children, that is, occupant 300 in seat body 400 is protected.
When matching air bag module 1 and child safety seat, as shown in figure 4, air bag module 1 also wraps
The second sensing device 17 is included, the second sensing device 17 is for detecting whether have children's sitting in seat body 400, the second sensing dress
It sets 17 to be electrically connected with controller 12, power supply device 16 can also power to the second sensing device 17.When the second sensing device 17 is examined
Measure someone's sitting in seat body 400, and the first sensing device 11 detect automobile collide signal when, controller 12 is sent out
To air charging system 13, air charging system 13 starts to be inflated signal to airbag body 14 out, expands airbag body 14, it is anti-to form safety
Shield；When the second sensing device 17 detects unmanned sitting in seat body 400, even if the first sensing device 11 detects automobile
The signal to collide, sender number, airbag body 14 are not in the state shunk to controller 12 always yet.
