Description
Technical field
The utility model relates to vehicle technology field, is specifically related to a kind of air bag device for automobile rear safety guard-safeguard.
Background technology
The safety air bag of automobile is intended to alleviate automobile and meets with after collision, and passenger is because of the extent of injury of inertia generation secondary collision.At present vehicle airbag be just mostly distributed in car, co-driver front, some also has air bag in rear row side.But; for automobile rear midway location; in collision process; the main still body-restraining seat belt of protection that the occupant of this position is subject to, can fix occupant's buttocks displacement, and the head of middle passenger is protected to deficiency; if generation sharp impacts; middle passenger head can impact forward, with front-row seats or front-row occupant generation sharp impacts, the personal safety of arranging midway location occupant after serious threat.
Summary of the invention
In view of this, the utility model proposes a kind of air bag device for automobile rear safety guard-safeguard, by arranging air bag module at roof liner, firing air bag in the time of vehicle generation sharp impacts, plays a protective role to rear row's midway location occupant.
The utility model provides a kind of air bag device for automobile rear safety guard-safeguard, comprising: automobile roof liner and air bag module, and wherein, automobile roof liner is positioned in automobile bodies top inner surface, and air bag module is contained in automobile roof liner; Described air bag module comprises safety air bag body and air bag is ignited unit, and wherein air bag ignition unit is connected with the collision alarm sensor electrical of automobile.
Preferably, be contained in the safety air bag body of automobile roof liner through arranging, ignited after unit ignition when safety air bag body by air bag, safety air bag body extends to the secondary instrument desk of automobile and the both sides of front-row seats.
Preferably, described safety air bag body is gas curtain.
Preferably, described air bag ignition unit is connected with described collision alarm sensor electrical by automobile bus.
Preferably, ignite between unit and described collision alarm sensor and be connected with automobile body control module BCM at described air bag.
The beneficial effects of the utility model: the utility model passes through at automobile roof liner mounting arrangements air bag module; the energizing signal of this module is from the collection of car load collision alarm; when after vehicle generation sharp impacts; collision alarm sensor is collected collision alarm; in the time that signal strength exceedes activation threshold value; air bag module will be triggered, and air bag is detonated, thereby the head and neck of passenger in the middle of rear row is played to good protective effect.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is described in detail.
Fig. 1 shows the structured flowchart of the air bag device for automobile rear safety guard-safeguard of the present utility model, this device comprises air bag module and can hold the automobile roof liner of air bag module, automobile roof liner is positioned at car body top inside face, wherein air bag module comprises safety air bag body and air bag ignition unit, air bag is ignited unit and is connected with the collision alarm sensor electrical of automobile, in the time satisfying condition, air bag is ignited unit and is triggered, safety air bag is detonated, passenger is formed to protection, because the position of automobile roof liner has covered rear row's zone line, therefore this safety air bag can form safety guard-safeguard to passenger in the middle of rear row after producing.
Fig. 2 shows the logical flow chart of air bag device of the present utility model, after automobile bumps, air bag module in roof liner receives the collision alarm of vehicle collision signal sensor, if the trigger condition that signal strength does not meet air bag ignites unit, flow process finishes; If meet, safety air bag ignited.
Fig. 3 shows the actuating logic block diagram of the each parts of air bag device of another embodiment of the utility model, air bag device gathers sensor-based system based on car load collision information, air bag module is through BCM (Body Control Module, automobile body control module) collision alarm of Receiving collision signal transducer, after BCM Receiving collision sensor signal, judge whether signal strength reaches initiation threshold, if the intensity of collision alarm arrives or exceedes predetermined ignition threshold values (meet air bag and ignite the trigger condition of unit), sensor signal result is exported to roof liner air bag module by BCM, air bag is ignited unit and is triggered, air bag module is detonated.Air bag is produced from roof liner, the head to rear row's midway location occupant and neck formation protection.Otherwise, if the intensity of collision alarm is not lower than this ignition threshold values (meeting trigger condition), collision alarm not to be processed, air bag device can not be triggered.
In embodiment of the present utility model, air bag module is arranged in automobile roof liner, the position (representing with solid line boxes) of " roof liner air bag " as shown in Figure 4, and the region at roof liner air bag place is just to arranging midway location region after vehicle.In addition, in Fig. 4, also show in the past common " front-seat air bag " and the position (representing with dashed rectangle) of " side gas curtain ".Contrast by Fig. 4 can be seen; the region of row's midway location after safety air bag of the present utility model can cover in compartment; in the time that automobile meets with intense impact; the region that safety air bag of the present utility model can not cover conventional balloon forms supplementary, arranges the occupant safety of midway location behind protection compartment.
In embodiment of the present utility model, the space that the utility model is arranged midway location after can filling should note guaranteeing air bag ignition in the time of layout air bag after, extends to secondary instrument desk and front-row seats both sides, desirable good protection effect.
In embodiment of the present utility model, such as, according to the pattern of vehicle and roof liner (space, compartment is larger or less, roof liner on have the situations such as skylight), can use gas curtain to replace air bag, or by actual demand flexible design air bag pattern.
In embodiment of the present utility model, air bag module is connected with the collision alarm sensor electrical of automobile by automobile bus, can directly adopt the collection of car load collision alarm, the maximization of row's middle passenger safety after ensureing.
Above, in conjunction with specific embodiments the technical solution of the utility model is described in detail, described specific embodiment is used for helping to understand thought of the present utility model.Within the derivation that those skilled in the art make on the basis of the utility model specific embodiment and modification also belong to the utility model protection domain.
