Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of buffer device for collision of automobile, particularly a kind of automobile side impact shock absorber.
Background technology
Arrangements for automotive doors is positioned at Vehicular side body, and car door is divided into along open type car door, contrary open type car door, horizontal movable type car door and lifting type door, facilitates passenger getting on/off.The crashworthiness of car door is the important indicator that determines car door quality, is also the key factor that determines vehicle safety performance.But in existing automobile, the intensity of car door seems comparatively weak with respect to other parts of automobile.In collision process, side impact belongs to the collision of rigidity substantially, after being clashed into, car door easily deforms, and chaufeur or passenger in the material invasion interior space injury car after distortion.
In prior art, the injury that crash bar causes to alleviate collision is set in car door body conventionally.In actual use, such structure still cannot meet the requirement of customer to vehicle safety performance.For further improving the crashproof ability of car door, production firm is by automobile side, buffer air bag being set, in order to the rigid collision of side is converted into flexible impact.For example, Chinese patent [patent No. 201120404480.X; Granted publication CN202429163U] disclosed a kind of automobile side impact occupant restraint system; it comprises system module and door skin line of weakness; system module is made up of air bag module adapter plate, gas generator and foldable formed airbag; air bag producer is connected with foldable formed airbag; both are installed on air bag module adapter plate; door skin line of weakness is positioned at door skin bottom, and system module is corresponding with the region that door skin line of weakness is surrounded.
Above-mentioned automobile side impact occupant restraint system has improved the crashproof ability of automobile side by buffer air bag is set; but; the problem that this automobile side impact occupant restraint system exists is; buffer air bag is fixed on car door by adapter plate; need to carry out larger change to the structure of car door itself, the installation inconvenience of buffer air bag.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of automobile side impact shock absorber, and the technical matters that the utility model solves is to make buffer air bag installation more convenient.
The purpose of this utility model can realize by following technical proposal: a kind of automobile side impact shock absorber, arrangements for automotive doors comprises car door body, collision prevention girders and trim panel, described collision prevention girders is fixed in car door body, it is characterized in that, this side collision shock absorber comprises and is arranged on the intrinsic buffer air bag of car door, for the signal of surveying the sensor of surrounding vehicles and send for receiving sensor the controller of controlling buffer air bag inflation, described sensor setting is on vehicle body, described buffer air bag is fixed in collision prevention girders, after described buffer air bag inflation, be filled between car door body and trim panel.
The principle of work of this automobile side impact shock absorber is: in vehicle traveling process, whether the signal that controller receiving sensor sends, can bump with this car by processing and compare rear judgement vehicle around.In the time that controller is determined with vehicle and may bumps with this car, controller control is about to occur to clash into the buffer air bag inflation of a side.After buffer air bag inflation, be filled between car door body and trim panel, External Force Acting on car door body after, the buffer air bag expanding plays buffer action to impact, by moment rigid impact be converted into the flexible impact with damping, reduced and invaded interior space after car door distortion and cause the possibility to passenger's injury.The buffer air bag of this automobile side impact shock absorber is installed by the existing collision prevention girders of car door body, easy for installation, less on the impact of car door body self structure, and good buffer effect to outside impact.
In above-mentioned automobile side impact shock absorber, in described collision prevention girders, there are multiple lugs, above-mentioned lug all has mounting hole, and described buffer air bag is bolted on lug.In the manufacturing, only need in collision prevention girders, weld lug, bolt easy for installation.
As preferably, in above-mentioned automobile side impact shock absorber, the shell of described buffer air bag is square, the quantity of described lug is 4, described lug is positioned at the both sides of collision prevention girders, and lug lays respectively on four angles of buffer air bag shell in the time that buffer air bag is installed in collision prevention girders.Fixing of buffer air bag shell and collision prevention girders is reliable, and buffer air bag is difficult for occurrence positions skew under collision and causes buffering effect to decline.
In above-mentioned automobile side impact shock absorber, described sensor detects travel direction and the moving velocity of surrounding vehicles, and the driving information of the surrounding vehicles that described controller receiving sensor sends is also compared with the driving information of this car and judged whether two cars can bump.Travel to this car when controller is determined with vehicle, and present speed moving velocity is greater than the moving velocity of this car, controller judges that this vehicle may bump with this car.
In above-mentioned automobile side impact shock absorber, described sensor is camera, the image of described camera Real-time Collection surrounding vehicles also sends to controller, and described controller obtains travel direction and the moving velocity information of surrounding vehicles by spectral analysis.
In above-mentioned automobile side impact shock absorber, described sensor is radar.By electromagnetic wave detection vehicle or obstacle around, accuracy rate is high.
In above-mentioned automobile side impact shock absorber, described sensor setting is on the back-mirror housing of automobile.Sensor senses scope is wider, can survey from back mirror front or the approaching vehicle of proceeds posterolateral, has improved the accuracy of sensor; The installation of sensor and wiring have utilized the space in back-mirror housing, easy for installation.
Compared with prior art, the advantage of this automobile side impact shock absorber is:
1, this automobile side impact shock absorber plays buffer action by buffer air bag to impact in the time that collision occurs, by moment rigid impact be converted into the flexible impact with damping, after having reduced car door distortion, intrusion interior space causes the possibility to passenger's injury, the anti-side impact ability that has improved automobile, the general safety performance of automobile is good.
2, the buffer air bag of this automobile side impact shock absorber is installed by existing collision prevention girders on car door body, and the housing of buffer air bag adopts on the lug being bolted in collision prevention girders, easy for installation; Structure influence to car door body is little, low cost of manufacture.
3, the installation of sensors of this automobile side impact shock absorber is on the back-mirror housing of automobile, and sensor senses scope is wider, can survey from back mirror front or the approaching vehicle of proceeds posterolateral, has improved the accuracy of sensor; The installation of sensor and wiring have utilized the space in back-mirror housing, easy for installation.
