Abstract
The utility model discloses an anti-collision beam structure for a car door. The anti-collision beam structure comprises a main transverse beam. The two ends of the main transverse beam are fixedly connected to a car door inner plate welding assembly. One longitudinal side or two longitudinal sides of the main transverse beam are provided with anti-collision beam branches. Included angles are formed between the anti-collision beam branches and the main transverse beam. According to the anti-collision beam structure for the car door, a car door anti-collision beam including one or more branch structures is adopted, the stamping technology is adopted on the anti-collision beam, the branch structures of the anti-collision beam can be obtained according to the performance conversion structure and position of a car door assembly, design flexibility is improved, the number of parts is reduced, and obvious advantages exist in both logistics and storage.
Description
Technical field
The utility model relates to technical field of automobile parts, refers to particularly a kind of anti-collision beam structure of car.
Background technology
Along with automobile pollution increases severely; traffic accident is significantly ascendant trend; wherein; automobile side shock accident occupies the first place of urban traffic accident; automotive side face collision safety is one of automobile vehicle performance index of paramount importance; automobile side narrow space; be unfavorable for that design complex configurations is to absorb collision energy; it is the weaker position of intensity in car body; and door anti-collision joist is as the extra energy-absorbing fender guard of one; that fore-and-aft direction adds entablatrance on inner plate of car door, to strengthen the rigidity of car door.
In order to improve automotive performance and safe class, as shown in Figure 1, general car door all adopts a door anti-collision joist or multiple crossbeam 3 that runs through to realize, the two ends of running through crossbeam 3 are welded on car door back veneer welding assembly 4, although can meet the demands on intensity and energy absorption performance, but no matter be one or multiple crossbeam that runs through, at design flexibility, in logistics and storage, all exist obvious deficiency.
Therefore, need improve prior art.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, and a kind of power in collision process and anti-collision beam structure of car of energy of can actv. transmitting is provided.
The technical solution of the utility model is: a kind of anti-collision beam structure of car, it comprises that two ends are fixedly connected on the main beam on car door back veneer welding assembly, is characterized in that: longitudinal one or both sides of described main beam are provided with collision prevention girders branch.
In such scheme:
Longitudinal side of described main beam is provided with the first collision prevention girders branch, and longitudinal opposite side of main beam is provided with the second collision prevention girders branch.
Door skin is close to by described the first collision prevention girders branch, and its end is fixedly connected on door skin or door skin strength beam.
Door skin is close to by described the second collision prevention girders branch, and its end is fixedly connected on door skin or car door back veneer.
The cross section of described main beam is " D " type, " M " type or " S " type.
Anti-collision beam structure of car shown in the utility model, it adopts a kind of door anti-collision joist that contains one or more branched structures, collision prevention girders adopts Sheet Metal Forming Technology, collision prevention girders branched structure can meet according to car door assembly performance mapped structure and position, strengthened design flexibility, reduce amount of parts, in logistics and storage, all had clear superiority.
Accompanying drawing explanation
Fig. 1 is existing anti-collision beam structure of car schematic diagram;
Fig. 2 is the utility model schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Existing anti-collision beam structure of car is explained in detail in background technology as shown in Figure 1, in this, repeats no more.
As shown in Figure 2, a kind of anti-collision beam structure of car of the present utility model, it comprise two ends pass through welding, the modes such as riveted joint or bolt are fixedly connected on the main beam 2 on car door back veneer welding assembly 1, the cross section of main beam 2 is " D " type, " M " type or " S " type, longitudinal one or both sides of main beam 2 are provided with collision prevention girders branch, and collision prevention girders branch and main beam 3 have certain angle.
In this enforcement:
Longitudinal side of main beam 2 is provided with the first collision prevention girders branch 2.1, and longitudinal opposite side of main beam 2 is provided with the second collision prevention girders branch 2.2.
The main body of the first collision prevention girders branch 2.1 is fitted by structural adhesion or damping rubber and door skin, and its end, by gluing or be welded and fixed and be connected on door skin or door skin strength beam, is connected with car door upper end to realize anti-collision beam structure of car.
The main body of the second collision prevention girders branch 2.2 is fitted by structural adhesion or damping rubber and door skin, and its end, by gluing or be welded and fixed and be connected on door skin or car door back veneer, is connected with car door lower end to realize anti-collision beam structure of car.
In the utility model: main beam 2 reticulates structure by before and after car door with one or more branch shape, and upper and lower part couples together, and makes car door form an entirety, can transmit power and the energy in collision process by actv., improves safety.
Anti-collision beam structure of car shown in the utility model, it adopts a kind of door anti-collision joist that contains one or more branched structures, collision prevention girders adopts Sheet Metal Forming Technology, collision prevention girders branched structure can meet according to car door assembly performance mapped structure and position, strengthened design flexibility, reduce amount of parts, in logistics and storage, all had clear superiority.
