Description
Technical field
The present invention relates to technical field of automobile parts, particularly to a kind of automobile frame collision prevention girders.
Background technology
At present, major part car and offroad vehicle are mounted on collision prevention girders, but owing to passenger vehicle is installed collision prevention girders temporarily without Compulsory Feature by state's laws, when bus driving process collides, owing to lacking collision prevention girders, the safety of driver and front passenger is difficult to be guaranteed.
Summary of the invention
The technical problem to be solved in the present invention is to provide the automobile frame collision prevention girders of a kind of safety that can ensure driver and front passenger well.
nullIn order to solve above-mentioned technical problem，The present invention adopts the following technical scheme that a kind of automobile frame collision prevention girders，The first anti-collision beam and the second anti-collision beam including horizontally set、The first longitudinally disposed shock-absorbing longeron and the second shock-absorbing longeron、Angularly disposed support beam，Before described first shock-absorbing longeron、Rear end is connected with the first anti-collision beam and the second anti-collision beam respectively，The front end of described second shock-absorbing longeron is connected to the second anti-collision beam，Described first shock-absorbing longeron is provided with the first shock-absorbing groove，Described second shock-absorbing longeron is provided with the second shock-absorbing groove，On described second shock-absorbing longeron, the intensity of the second shock-absorbing groove is more than the intensity of the first shock-absorbing groove on the first shock-absorbing longeron，Described first shock-absorbing longeron、The quantity of the second shock-absorbing longeron and support beam is at least two，Described second anti-collision beam has elongated hole，Described elongated hole is arranged along the length direction of the second anti-collision beam，Described support beam is arranged in a crossed manner in pairs and hinged by swivel pin in its intersection area，One end of described support beam is connected to elongated hole by swivel pin or bolt，The other end of described support beam is articulated with the second shock-absorbing longeron，The pin joint of described support beam and the second shock-absorbing longeron is positioned at the rear of the second shock-absorbing groove.
Further, described first anti-collision beam, the second anti-collision beam, the first shock-absorbing longeron, the second shock-absorbing longeron and support beam are made by aluminum alloy materials.
nullWhat the present invention obtained has the beneficial effects that: the present invention is by arranging the first anti-collision beam、Second anti-collision beam、、First shock-absorbing longeron、Second shock-absorbing longeron and support beam，When a collision occurs，First first shock-absorbing groove ruptures，Then the second anti-collision beam and the second shock-absorbing longeron start to bear the second wave impact，If Impact energy is bigger，Second shock-absorbing groove fracture，Now the second anti-collision beam starts to retreat，Drive simultaneously and support beam setting in motion，When supporting the swivel pin of beam and the second anti-collision beam connection or bolt movement to the two ends of elongated hole，Second anti-collision beam and support beam stop motion，Owing to " having laid down " most Impact energy when front twice fracture occurs，Therefore the second anti-collision beam and support beam can sustain the 3rd wave impact in whole collision process well，Thus ensure that the safety of driver and front passenger.

Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with embodiment, the present invention is further illustrated with accompanying drawing, and the content that embodiment is mentioned not is limitation of the invention.
nullAs shown in Figure 1，A kind of automobile frame collision prevention girders，The first anti-collision beam 1 and the second anti-collision beam 2 including horizontally set、The first longitudinally disposed shock-absorbing longeron 3 and the second shock-absorbing longeron 4、Angularly disposed support beam 5，Before described first shock-absorbing longeron 3、Rear end is connected with the first anti-collision beam 1 and the second anti-collision beam 2 respectively，The front end of described second shock-absorbing longeron 4 is connected to the second anti-collision beam 2，Described first shock-absorbing longeron 3 is provided with the first shock-absorbing groove 31，Described second shock-absorbing longeron 4 is provided with the second shock-absorbing groove 41，On described second shock-absorbing longeron 4, the intensity at the second shock-absorbing groove 41 place is more than the intensity at the first shock-absorbing groove 31 place on the first shock-absorbing longeron 3，Described first shock-absorbing longeron 3、The quantity of the second shock-absorbing longeron 4 and support beam 5 is at least two，Described second anti-collision beam 2 has elongated hole 21，Described elongated hole 21 is arranged along the length direction of the second anti-collision beam 2，Described support beam 5 is arranged in a crossed manner in pairs and hinged by swivel pin in its intersection area，One end of described support beam 5 is connected to elongated hole 21 by swivel pin or bolt，The other end of described support beam 5 is articulated with the second shock-absorbing longeron 4，The pin joint of described support beam 5 and the second shock-absorbing longeron 4 is positioned at the rear of the second shock-absorbing groove 41.
nullIn the above-described embodiments，The present invention is by arranging the first anti-collision beam 1、Second crashproof horizontal 2 beams、、First shock-absorbing longeron 3、Second shock-absorbing longeron 4 and support beam 5，When a collision occurs，First first shock-absorbing groove 31 place ruptures，Then the second anti-collision beam 2 and the second shock-absorbing longeron 4 start to bear the second wave impact，If Impact energy is bigger，The fracture of second shock-absorbing groove 41 place，Now the second anti-collision beam 2 starts to retreat，Drive simultaneously and support beam 5 setting in motion，When supporting the swivel pin that is connected with the second anti-collision beam 2 of beam 5 or bolt movement to the two ends of elongated hole 21，Second anti-collision beam 2 and support beam 5 stop motion，Owing to " having laid down " most Impact energy when front twice fracture occurs，Therefore the second anti-collision beam 2 and support beam 5 can sustain the 3rd wave impact in whole collision process well，Thus ensure that the safety of driver and front passenger.
Further, described first anti-collision beam the 1, second anti-collision beam the 2, first shock-absorbing longeron the 3, second shock-absorbing longeron 4 and support beam 5 are made by aluminum alloy materials.
Aluminum alloy material has feature lightweight, that intensity is high, adopt aluminum alloy materials to make first anti-collision beam the 1, second anti-collision beam the 2, first shock-absorbing longeron the 3, second shock-absorbing longeron 4 and support beam 5 had not both resulted in oil consumption in car running process and increased too much, in turn ensure that the anti-collision effect of collision prevention girders.
Above-described embodiment is the present invention preferably implementation, and in addition, the present invention can also realize by alternate manner, and under the premise conceived without departing from the technical program, any apparent replacement is all within protection scope of the present invention.
Finally, it should be emphasized that, in order to allow those of ordinary skill in the art understand the present invention improvements relative to prior art more easily, some charts of the present invention and description are simplified, and for the sake of clarity, present specification is omitted some other elements, and those of ordinary skill in the art it is to be appreciated that these elliptical elements also may make up present disclosure.
