Description
Technical Field
The utility model relates to a car frame, concretely relates to front impact crossbeam structure, specially adapted middle and high end pick up car.
Background
At present, front collision beams on the domestic market have various shapes and are mostly realized by adopting a stamping process; the damage value caused by collision is reduced by means of the structure of the energy absorption box, and the mounting mode is mainly that the artificial bolt is tightened after being positioned. CN208291339U discloses an "automobile front collision beam assembly", including front beam body, two energy-absorbing boxes and two connecting plates, two energy-absorbing boxes are located front beam body both ends, and the energy-absorbing box front end is fixed connection with the trailing flank of front beam body, and rear end and connecting plate fixed connection are equipped with the installation via hole of being connected with the longeron on the connecting plate, the energy-absorbing box is the cavity drum shape that the centre is big, both ends are little. The strength requirement on the energy absorption box during the frontal collision of the whole vehicle can be met, and the collision performance is improved. The material utilization rate of the front collision beam manufactured by adopting the stamping process is low, so that the cost is increased. In addition, the development of the energy absorption box of the front collision beam increases the weight of the whole vehicle and also exerts certain pressure on the cost of the vehicle. In addition, the existing front collision beam is not provided with a mounting and positioning structure, and a manual bolt is needed to be positioned firstly and then tightened in the mounting process, so that the loading beat is delayed. Accordingly, there is a need for further improvements in existing front impact cross members.
Disclosure of Invention
The utility model aims at providing a front collision crossbeam structure, its structure is succinct, and the wholeness is strong, and the installation of being convenient for can improve material utilization, reduce cost.
A front collision crossbeam structure, including the crossbeam body, characterized by: the beam body is a rolled and integrally formed sheet metal part and is provided with an upper cavity and a lower cavity, and the section of the beam body is B-shaped; a main positioning hole is formed in the left end of the upper portion of the beam body, and a secondary positioning hole is formed in the right end of the upper portion of the beam body; and the left end part and the right end part of the lower part of the beam body are respectively provided with a mounting hole.
Furthermore, a pre-hanging hole is respectively formed in the left end portion and the right end portion of the upper portion of the beam body.
Further, the beam body is self-welded in the middle of the beam body, and 30mm equidistant spot welding is adopted.
Further, the cross sections of the upper cavity and the lower cavity of the beam body are both 39mm and 30 mm.
Furthermore, the beam body is made of B440/780DP cold-rolled sheet and treated by electrophoretic black paint.
Further, the pre-hanging hole is a rectangular hole.
The utility model has the advantages that: the beam body is designed into a closed cavity with a uniform section, and is integrally formed by rolling, so that the material utilization rate is improved, and the beam has important significance for platformization, weight reduction, cost reduction and the like; in addition, the front collision beam cancels an energy absorption box, and greatly reduces the development cost and the development period of the vehicle under the condition of meeting the requirements of collision safety (direct collision, offset collision and column collision); due to the arrangement of the pre-hanging structure, the operation assembly performance of workers is improved, unnecessary waste of time is reduced, and the production takt is improved.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, 2, 3 and 4, a front impact cross member structure includes a cross member body 1, and is characterized in that: the beam body 1 is a rolled and integrally formed sheet metal part and is provided with an upper cavity and a lower cavity, and the section of the beam body is B-shaped; the sheet materials are integrally formed by rolling, so that the number of parts is reduced, the utilization rate of the materials is improved, and the manufacturing cost is reduced.
A main positioning hole 11 is formed in the left end of the upper portion of the beam body 1, and a secondary positioning hole 12 is formed in the right end of the upper portion of the beam body; a mounting hole 13 is respectively arranged at the left end part and the right end part of the lower part of the beam body 1. The crossbeam body passes through bolt and main locating hole, inferior locating hole and two mounting holes cooperation direct mount on the frame crossbeam, and installation convenient operation, swift.
The left end and the right end of the upper part of the beam body 1 are respectively provided with a pre-hanging hole 14. When the installation, will hang the structure cooperation of leaning on with the hanging on the vehicle frame connecting plate in advance two on the crossbeam body, carry out preliminary location earlier, then, carry out the installation fixed operation of crossbeam body, make the man-hour of installation shorten, the installation effectiveness improves.
