Embodiment
Exemplary embodiment of the present utility model is more fully described below with reference to accompanying drawings.Although showing this in accompanying drawing
The exemplary embodiment of utility model, it being understood, however, that may be realized in various forms the utility model without should be by here
The embodiment of elaboration is limited.Conversely it is able to be best understood from the utility model, and energy there is provided these embodiments
It is enough by scope of the present utility model completely convey to those skilled in the art.
Such as Fig. 1 and Fig. 2 shows that embodiment of the present utility model provides a kind of vehicle front bumper arrangement, specifically includes：Before
Bumper body 1, gas generator 2, the first air bag 3, the second air bag 4 and pressure-reducing valve 5.Wherein, front bumper body 1 is arranged at
Body forward structure, gas generator 2 is used to instantaneously produce a large amount of gases, is arranged in the side that front bumper body 1 extends to vehicle body,
Or be the inner side of front bumper body 1.First air bag 3 and the second air bag 4 are used to eject to protect when occurring traffic accident
Pedestrains safety is protected, specifically, the first air bag 3 and the second air bag 4 include the compressive state being embedded in front bumper body 1, with
And eject the swelling state for deviating from vehicle body side in front bumper body 1, that is, eject the inflation shape outside front bumper body 1
State is to reduce injury of the vehicle body to pedestrian.Wherein, the first air bag 3 is directly connected with gas generator 2, the second air bag 4 by using
Connected in the pressure-reducing valve 5 of reduction gas pressure intensity with gas generator 2, i.e., one end of pressure-reducing valve 5 is connected with the second air bag 4, another
End is connected with gas generator 2.
So, in normal driving conditions, the first air bag 3 and the second air bag 4 are in compressive state, are embedded at before automobile
In bumper body 1, once there is Traffic Collision accident, gas generator 2 produces rapidly a large amount of gases, and gas is conveyed
To the first air bag 3 and the second air bag 4, because the first air bag 3 is directly connected with gas generator 2, therefore the first air bag 3 have compared with
Atmospheric pressure, impulsive force of the vehicle body to pedestrian can be buffered well；Pass through pressure-reducing valve 5 and gas further as the second air bag 4
Generator 2 is connected, therefore the air pressure in the second air bag 4 is less than the air pressure in the first air bag 3, can further buffer 3 pairs of the first air bag
The impulsive force of pedestrian, to reduce or avoid the secondary injury of pedestrian, improves its security.Preferably, the surface area of the second air bag 4
More than the surface area of the first air bag 3, then the filled volume of the second air bag 4 is more than the filled volume of the first air bag 3, it is preferable that
The filled volume of second air bag 4 can be set to 3~5 times of the filled volume of the first air bag 3.
Alternatively, as shown in figure 1, being additionally provided with a groove structure 11 on front bumper body 1, the first air bag 3 and second
Air bag 4 is placed in when in compressive state in the groove structure 11.
Alternatively, as shown in figure 3, vehicle front bumper arrangement of the present utility model also includes：One comparator and it is arranged in
Sensor on front bumper body 1.Wherein one end of comparator is connected with gas generator 2, the other end and biography of comparator
Sensor is connected.Specifically, sensor is used for the distance between acceleration and vehicle and pedestrian of collection vehicle and is sent to ratio
Compared with device, comparator be used to comparing the distance between relation between vehicle acceleration and acceleration rate threshold, and traffic with
The relation of distance threshold.Comparator is additionally operable to control the working condition of gas generator 2 according to above two relation, so as to realize
Inflation to the first air bag 3 and the second air bag 4.Specifically, during the traveling of automobile, sensor (range unit) is examined in real time
The distance between automobile front beam and pedestrian are surveyed, and the distance value collected is transferred to comparator, works as automobile front beam
When will collide pedestrian and take brake hard, sensor further detects the velocity amplitude and acceleration magnitude of now automobile, and
Comparator will be sent to；Comparator detect distance value and velocity amplitude and acceleration magnitude meet or exceed restriction threshold value when,
Start gas generator 2, operation is inflated to the first air bag 3 and the second air bag 4, the first air bag 3 and the second air bag 4 is inflated
After open, so as to slow down the shock dynamics to pedestrian, protect pedestrains safety.Wherein, limiting threshold value can set according to the actual requirements,
Speed threshold value is for example set as 20km/h, distance threshold is set as 0.5m, then when comparator detects distance value and speed
When angle value and acceleration magnitude meet or exceed restriction threshold value, gas generator 2 is excited, and rapid produce expands after excitation
Gas, a portion gas is directly entered in the first air bag 3, and another part enters the second air bag 4 after being depressured through pressure-reducing valve 5
In so that the pressure of the first air bag 3 is higher than the pressure of the second air bag 4.So, the first air bag 3 is just played a supporting role, the second gas
Capsule 4 then plays cushioning effect.After vehicle collides, the second air bag 4 is hit in the leg of pedestrian first, due to the second air bag 4
The blowing pressure is relatively low, serves cushioning effect, it is to avoid direct first air bag 3 in leg, reduces the injury to pedestrian lower leg.
Other side according to the utility model embodiment is additionally provided before a kind of automobile, including automobile as described above
Bumper, the embodiment that above-mentioned automobile front beam is realized can reach phase suitable for the embodiment of this automobile
Same effect.
Above-described is preferred embodiment of the present utility model, it should be pointed out that for the ordinary person of the art
For, some improvements and modifications can also be made under the premise of principle described in the utility model is not departed from, these improve and moistened
Decorations are also in protection domain of the present utility model.
