Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See Fig. 1 ~ 4, a kind of airbag apparatus of chaufeur foot of protecting is provided to the utility model embodiment and is described in detail.A kind of airbag apparatus of chaufeur foot of protecting that the utility model embodiment provides comprises air bag 6 and gas generator 9, wherein:
Described air bag 6, is arranged on the body platform 5 of chaufeur foot 3 position, to be specifically located on automobile dash board 1 and the transitional region of body platform 5 and to be positioned at below Das Gaspedal 2.Described gas generator 9 is arranged on bottom air bag 6, for inflating to described air bag 6 and making it launch.
In an embodiment of the present utility model, airbag apparatus can also comprise the carpet 4 covering air bag 6 surface, because air bag 6 is positioned at below chaufeur foot 3 position, be arranged on automobile dash board 1 with in the transitional region of body platform 5, be all generally concave shape at an angle, air bag 6 is just in time arranged on herein in sunk area, therefore can not impact car carpeting 4 appearance herein, under the non-deployed condition of air bag 6, air bag 6 can also serve as interim footrest and cushion rubber effect.And will lower than the structural strength at other positions of carpet 4 with the structural strength of described air bag 6 contact site on carpet 4, namely local weakness is carried out to carpet 4, in automobile collision procedure, this part carpet 4 is torn than being easier to, thus guide air bag 6 to detonate from tear place, guarantee that air bag 6 launches completely within the shortest time.
The highest expansion pressure of the gas that gas generator 9 of the present utility model produces should be greater than 160kPa, and opening completely for air bag 6 provides sufficient pressure, ensures that air bag 6 can be opened fast.Described air bag 6 side is provided with bleeder port 7, can ensure that air bag 6 can be exitted after launching as soon as possible, avoid driver.
See Fig. 4, the gas generator 9 of the airbag apparatus of the protection chaufeur foot that the utility model provides is electrically connected the ECU20 of automobile, and ECU20 is electrically connected sensor (the present embodiment comprises impact strength sensor 22 and collision protection sensor 21).ECU20 judges vehicle collision intensity according to the information that sensor detected vehicle transmits, and when impact strength reaches setting safety value, sends instruction, thus start described gas generator 9 and inflate to described air bag 6 to gas generator 9.
See Fig. 1 ~ 3, the structure of the airbag apparatus of the protection chaufeur foot that the utility model provides is described in detail.Wherein, described air bag 6 is fixedly installed to be located on automobile dash board 1 and the transitional region of body platform 5 and to be positioned at below Das Gaspedal 2, the middle and upper part of described air bag 6 is provided with groove 10, when colliding, gas generator 9 controls to inflate to described air bag 6 by ECU, described air bag 6 is inflated and is expanded, and described air bag 6 can promote described Das Gaspedal 2 and reset (up to be pushed away by chaufeur right crus of diaphragm 3) in expansion phase, and chaufeur foot 3 can be made away from the intrusion of front wall.In addition, when described air bag 6 expands, described Das Gaspedal 2 is fitted completely and is contained in the described groove 10 of described air bag 6, like this, described air bag 6 and described Das Gaspedal 2 form a complete supporting plane, make chaufeur foot 3 obtain a complete bearing surface.In addition, when impact strength strengthens, chaufeur foot 3 steps down on a large and smooth bearing surface, and air bag 6 begins through bleeder port 7 and to lose heart buffering energy-absorbing simultaneously, reaches the protective effect to chaufeur foot 3.
In the present embodiment, described groove 10 is consistent with the size of described Das Gaspedal 2, shape when described air bag 6 expands, thus can accommodate described Das Gaspedal 2 completely, makes described air bag 6 and Das Gaspedal 2 form a complete supporting plane.
In addition, the airbag apparatus of the present embodiment also comprise connect bottom described groove 10 with air bag 6 bottom drawstring 8.Concrete, drawstring 8 is positioned at the below of described groove 10 and is placed in described air bag 6 inside, and after described air bag 6 is inflated, described drawstring 8 is stretched, after air bag 6 is full of, by described drawstring 8 to the pulling force bottom described groove 10, thus control the shape of retaining groove 10.
Understandable, sensor of the present utility model can be multiple sensors, such as speed, acceleration/accel etc.In this example, sensor comprises the impact strength sensor 22 being arranged on automotive front, detects the deceleration/decel of automobile.The deceleration/decel detected is sent to ECU20 by impact strength sensor 22.ECU20 is preset with deceleration/decel threshold values, in the collision detection process that impact strength sensor 22 sends by ECU20, the deceleration/decel of automobile compares with the deceleration/decel threshold values preset, draw the severity of collision, when the deceleration/decel that the impact strength sensor 22 that ECU20 receives sends exceedes default deceleration/decel threshold values, then send instruction to gas generator 9, start described gas generator 9 to inflate to described air bag 6, thus make described air bag 6 in inflation process, promote Das Gaspedal 2 to reset.
In addition, the sensor of the present embodiment can also arrange collision protection sensor 21, and collision protection sensor 21 is substantially identical with the structural principle of impact strength sensor 22, is also for the deceleration/decel got is sent to ECU20.Unlike, the deceleration/decel threshold values that ECU20 sets for collision protection sensor 21 is different with the deceleration/decel threshold value set for impact strength sensor 22.Therefore, the collision protection sensor 22 of the present embodiment be with impact strength sensor 21 with the use of, according to the combination of two sensor detection information, ECU20 judges whether that starting described gas generator 9 inflates to described air bag 6, prevents impact strength sensor 21 from causing anti-operation because of accidental short circuit.So the arranging of collision protection sensor 22 can increase the accuracy that the utility model controls, the unexpected situation of opening of described gas generator 9 is avoided to occur.
In sum, the airbag apparatus of the utility model disclosed protection chaufeur foot is by the transitional region that air bag is arranged on automobile dash board and body platform is positioned at below Das Gaspedal, groove is provided with in the middle part of described air bag, when colliding, described air bag is inflation under the effect of gas generator, air bag expands and Das Gaspedal is resetted, and makes chaufeur right crus of diaphragm away from the intrusion of front wall; The while that air bag expanding, groove can be fitted and accommodate described Das Gaspedal completely, thus form a complete supporting plane with described Das Gaspedal, make chaufeur right crus of diaphragm to support, and thus avoid chaufeur foot and easily to occur rivering bend the serious problem of pin, little sprain of leg.In addition, when impact strength strengthens, the bleeder port in described air bag is by the buffering energy-absorbing that loses heart, thus damping bouncing force in collision degree, weaken the degree that chaufeur is injured.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
