Description
Technical field
The utility model relates to automotive safety technology, is specifically related to the preventative buffer safety device of a kind of car and pedestrian impact or secondary collision.
Background technology
According to World Health Organigation's statistics, 46% in road traffic accident is died from every year in whole world person, is had to be vulnerable road user based on pedestrian.Make a general survey of Development history of automobile, people always are the safety only considering chaufeur and passenger inside the vehicle in automotive safety, but seldom pay close attention to the protection of pedestrian.After vehicle and pedestrian collision, the injury of the vehicle in traveling to people exists in two forms, comprises collision and rolls.When colliding, main position of collision is in the front bumper of automobile or front face position, and the method that domestic existing personnel propose to install at headstock two ends external air bag alleviates car and damages and improve occupant safely etc.But pedestrian and vehicle are after an impact, exist personnel's leap get up after may with the situation of the front windshield of vehicle or engine case generation secondary collision, secondary injury certainly will be caused to pedestrian.
Summary of the invention
The purpose of this utility model is situation when cannot avoid for car and pedestrian impact; as automobile active safety technology; there is provided a kind of can start rapidly and the preventative anticollision device of available protecting pedestrian; buffering car and pedestrian impact and under the extreme case of pedestrian and shield glass generation secondary collision, vehicle initiatively discharges external air bag and spreads in front windshield to reach protection pedestrian below engine case
,can prevent or reduce traffic accident injury when vehicle speed per hour is lower.
The utility model realizes above-mentioned purpose by the following technical solutions.The preventative safety device of a kind of car pedestrian impact, comprise car bonnet and be installed on the range only radar of car bonnet Inner Front End and the safety air bag of car bonnet rear end, in car bonnet, bearing is fixedly equipped with in both sides, between two bearings, thin axle is housed, support outer to be connected with one end of connecting rod by thin shaft end head and to have clamped torque spring, outside the other end of connecting rod, stand hinge is housed; Stand hinge connects one end of stay cord, and the other end of stay cord is connected with field core, and field core is connected with permanent magnet, has installed around excitation coil outside described field core; Range only radar and ECU(car running computer) be connected, ECU mouth connects excitation coil, safety air bag connection jaws and blinker signal line respectively.
In the utility model, a car bonnet and support thin axle is connected, the two ends connection bracket hinge of stay cord and field core.During without pre-impact perceptron signal, stay cord one end is adhesive tension under the suction of permanent magnet to field core, makes car bonnet be in closure state.Range only radar is placed in below engine case front end, and safety air bag is placed in below engine case rear end.When there is car pedestrian impact, come from after range only radar perception goes out the location information of pedestrian and send to ECU, ECU sends pre-impact perceptual signal to excitation coil after computing, and send the rotation around thin axle generation certain angle under the effect of torque spring of flash light drive singal car bonnet, realize the downward shift at edge before and after car bonnet, thus the safety air bag of the back lower place in car bonnet is ejected rapidly, place mat is on car bonnet and Windshield, and actv. prevents hard collision and the secondary collision of pedestrian and automobile.
Compared with prior art, its advantage is the utility model: can preventative buffering car and pedestrian impact and secondary collision effectively when car and pedestrian impact.By the parts that set up an organization in car bonnet; after the location information being measured pedestrian and car body by preposition radar probe; information is sent to vehicle-mounted ECU; ECU is after sending pre-impact perceptual signal to the backward excitation coil of the process of information; car bonnet leading edge offsets downward, and trailing edge upwards offsets, and safety air bag is opened rapidly; to guarantee to be paved with impingement region before pedestrian head clashes into car bonnet and Windshield, reach the effect initiatively protecting pedestrains safety.Its structure is simple, easy to use, easy-maintaining and replacing.

In figure: 1. thin axle, 2. torque spring, 3. car bonnet, 4. stay cord, 5. bearing, 6. connecting rod, 7, field core, 71. excitation coils, 8. permanent magnet, 9. stand hinge, 10. range only radar, 11. safety air bags, 12.ECU, 13. flash lights.
Detailed description of the invention
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments.See Fig. 1 to Fig. 4, the preventative safety device of a kind of car pedestrian impact, comprise car bonnet 3 and be installed on the range only radar 10 of car bonnet 3 Inner Front End and the safety air bag 11 of car bonnet 3 rear end, in car bonnet 3, bearing 5 is fixedly equipped with in both sides, between two bearings 5, thin axle 1 is housed, to be connected with one end of connecting rod 6 by thin axle 1 termination outside bearing 5 and to have clamped torque spring 2, stand hinge 9 is housed outside the other end of connecting rod 6; Stand hinge 9 connects one end of stay cord 4, and the other end of stay cord 4 is connected with field core 7, and field core 7 is connected with permanent magnet 8, has installed around excitation coil 71 outside described field core 7; Range only radar 10 is connected with ECU12, and ECU12 mouth connects excitation coil 71, safety air bag 11 connection jaws and flash light 13 signal wire (SW) respectively.
The utility model adds pedestrains safety Signal Analysis System, this system core is vehicle-mounted ECU 12, this system analyzes the signal that range only radar 10 transmits, identify the pedestrian in track, and the mode of motion of pedestrian is detected and analyzed, and the motoring condition of car is identified, sends drive singal to excitation coil 71 in emergency situations, reach to make accident before accident occurs and analyze accurately and judge.
The preventative safety device of a kind of car pedestrian impact, as shown in Figure 1: under car bonnet 3 lagging dege, install two symmetrical stay cords 4 additional, ensure that car bonnet 3 keeps original function when car normally travels.One end of stay cord 4 is placed on bonnet hinge 9, fixes car bonnet 3 with stay cord 4, does not allow car bonnet 3 move in car normal circumstances, plays the impact of buffering pedestrian crashes car bonnet 3 when crashing.The other end of stay cord 4 is connected with the field core 7 being connected permanent magnet 8, and field core 7 is wound with excitation coil 71, excitation coil 71 is power failure state under normal circumstances.When ECU12 send electric signal pass come time, excitation coil 71 rapidly energising produces magnetic field, and the magnetic field that field core 7 produces with permanent magnet 8 contact surface is identical with permanent magnet 8, and by homopolar-repulsion principle, field core 7 can hightail permanent magnet.
When car normally travels, car bonnet 3 is in normal condition, and torque spring 2 has certain twisting force on car bonnet 3, and stay cord 4 is held.When range only radar 10 has signal to transmit, stay cord 4 unclamps rapidly, and car bonnet 3, under the effect of torque spring 2, rotates to an angle for axle center with thin axle 1, and car bonnet 3 leading edge is offset downward, and trailing edge upwards offsets.Open rapidly under the signal that simultaneously safety air bag 11 transmits at ECU12, to guarantee the impingement region being paved with safety air bag 11 before pedestrian head clashes into car bonnet 3 and Windshield, reach the effect of protection pedestrains safety.
