Abstract
The invention relates to an automobile front collision cross beam mounting structure which comprises a front longitudinal beam and a front collision cross beam, wherein the front collision cross beam comprises a horizontal part and a longitudinal part which are welded together. The automobile front collision cross beam mounting structure is characterized in that the longitudinal part comprises a first box body structure which consists of a left part and a right part and forms a sealing space through welding; the front longitudinal beam comprises a sealed second box body structure formed by welding a body and side plates; the first box body structure is inserted in the second box body structure; the first box body structure and the second box body structure are in clearance fit with each other; and the matching parts of the first box body structure and the second box body structure are detachably connected. For the automobile front collision cross beam mounting structure, the front collision cross beam is directly inserted into a cavity of the front longitudinal beam; the front collision cross beam is connected on an automobile body through the connecting mode with the bolt and the nut on a main structural surface of the longitudinal beam, so that the number of parts is reduced, the manufacturing cost is reduced, the weight of the automobile body is reduced, the mounting points are distributed on the side surface of the longitudinal beam, so that the sheltering of the front collision cross beam to the mounting operation space is avoided, and the mounting operation is more convenient.
Description
Technical field
The present invention relates to a kind of automobile interior header structure, be specifically related to a kind of automobile with before bumping beam mounting structure.
Background technology
Now, auto-industry are fast-developing, and relevant laws and regulations require to improve constantly.Bump crossbeam before the automobile and constantly improving yet, but the preceding mounting means that bumps crossbeam and car body does not change as requisite parts of auto body.Bump beam mounting structure before traditional; Referring to Fig. 1-Fig. 2; Before bump crossbeam the lateral part generally form the osed top structure by transverse member 0021 and 0022 welding; The lateral part generally is welded with end adapter plate 0024 by square closed cross-section section bar 0023, and end adapter plate 0024 is vertical with the longitudinal direction of square closed cross-section section bar 0023, and lateral part and longitudinal component also are through being welded and fused; The leading section of front side member 0011 need design flange spare 0012 and end adapter plate 0014; The longitudinal component elder generation of flange spare 0012 and front side member 0011 welding; Its vertical part is welded with end adapter plate 0014 more then. be designed with 3 to 4 welded nuts 04 on the end adapter plate 0014 of front side member; Before bump on the end adapter plate 0024 of crossbeam and correspondingly open the bolt via hole, bump crossbeam before last to link into an integrated entity with the front side member of car body through bolt 03. such design demand all designs the adapter plate vertical with longitudinal direction in the end of preceding bumping crossbeam and front side member, and then the mode handle of employing bolt and nut before bumps crossbeam and is connected on the car body; Complex structure, cost is high; Because the attachment face of this structure is positioned on the horizontal vertical plane of front side member; The lateral part that the operational space of mounting tools is before bumped crossbeam easily during installation shelters from; Cause the fitting operation difficulty more; Or design adapter plate very greatly in order to satisfy the fitting operation space requirement, cause the increase of weight, cost.
Summary of the invention
The present invention is in order to overcome the deficiency of prior art, and a kind of automobile that provides is with before bumping beam mounting structure, and it is simple in structure; Reduce cost of development, alleviate tare, bump crossbeam blocking itself before covering out the fitting operation space; Arrange attachment point from the side, make when installing more convenient to operate.
The technical scheme that the present invention adopts:
It comprises front side member and before bumps crossbeam, precedingly bumps lateral part and the longitudinal component that crossbeam comprises weld together, and described longitudinal component comprises by left and right sides two parts with through welding and forms osed top first body structure; Described front side member comprises by body and side plate and is welded into leak free second body structure, and wherein, first body structure inserts second body structure, both free-running fits, and first body structure and the second body structure mating part removably connect.
The above-mentioned bolt screw that is detachably connected as connects, and is provided with screw at first body structure and the second body structure mating part, is provided with bolt in the screw.
Above-mentioned screw number is 4, each side 2.
Above-mentioned gap is 0.5mm.
The length of above-mentioned mating part is 30mm.
The technique effect that the present invention obtains:
1, the present invention has changed the connection structure of bumping crossbeam and car body before traditional; Cancelled the design of end adapter plate; Before bumping in the cavity that crossbeam directly inserts front side member, on the main structure surface of longeron, adopt the mode of bolt and nut connection to be connected on the car body before bumping crossbeam, reduced the part number; Reduce manufacturing cost, alleviated tare; Attachment point is arranged in the side of longeron, bumps crossbeam itself before having covered out during installation to the blocking of fitting operation space, and makes fitting operation convenient.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present invention is done further explanation.
Referring to Fig. 3-6, a kind of automobile relates generally to the front side member 1 of car body and before bumps crossbeam 2 with before bumping beam mounting structure, with respect to vertical vertical plane symmetry of vehicle body, only the right structure is described about this structure.Front side member 1 forms the osed top cavity body structure by body 11 and side plate 12 through spot welding, and being shaped as of cavity is square, but does not have special demands; Before bump crossbeam 2 by the lateral part consistent 22 with the overall width direction and with the front side member direction consistent longitudinal component 21 form; Both are through being welded and fused; 21 parts form the osed top structure by left and right sides two parts 211 and 212 through welding, and 21 parts have in one section long insertion front side member cavity of 30mm, shown in Fig. 5 section B-B; The tolerance clearance of insertion portion and front side member is 0.5mm; Evenly arrange 2 welded nuts 4 respectively on two faces about mating part, and open via hole, be fixed on the car body before bumping crossbeam through 4 bolts 3 during general assembly in the corresponding position of front side member.
Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of claim of the present invention and equivalent technologies thereof, then the intent of the present invention also comprises these changes and is out of shape interior.
