Abstract
Provided is an assembly structure of an automobile seat beam, including a seat beam body and a seat installing plate fixed on the seat beam body. The cross section of the seat beam body is in the structure a U-shaped groove, the two sides of the seat beam body are provided with flanging structures, the two ends of the seat beam body are provided with overlapping structures in the sheet metal connection with the lower bottom plate of a vehicle body, the flanging structures and the overlapping structures are smoothly connected into one body, an opening structure is arranged in the middle, and a bolt is arranged on the seat installing plate through projection welding. The assembly structure reduces the stress concentration at the opening while increasing the welding joints of the seat beam body, so that the strength of the seat beam body is enhanced. The projection welding bolt reduces the welding positioning holes on the seat beam body, so that the punching procedures are reduced, the strength of the seat beam body is enhanced, and the collision effect of an automobile is improved. The assembly structure provided can be widely applied to the field of automobile seat beams.
Description
Technical field
The utility model relates to a kind of crossbeam sheet metal structural, relates in particular to a kind of automotive seat crossbeam assembly structure.
Background technology
Existing C-NCAP Test item heavily has one for deformable, to move the test of obstacle side collision, self the intensity proposition very high requirement of this test to seat beam.Otherwise, when mobile obstacle vertically drives towards test vehicle with the collision velocity of 50km/h, the injured situation of the dummy of position of driver will very seriously even really can brought harm to the life of chaufeur under situation.Have breach between the landing edge at traditional Chinese chair crossbeam two side flangings and crossbeam two ends, during collision, often due to indentation, there stress, concentrate and to damage, thereby affect the Rigidity and strength of whole seat beam, reduce the collision effect.And what traditional chair mounted plate adopted is the project-welding nut mode, then on crossbeam, open the installation location of knock hole for seat, increased open-celled structure on the seat cross-beam body, affect the intensity of seat beam.
The utility model content
The purpose of this utility model is to provide a kind of automotive seat crossbeam assembly structure, solves existing seat beam assembly intensity difference, the low problem of collision effect.
The utility model solves the technical scheme that its technical matters adopts: a kind of automotive seat crossbeam assembly structure, comprise the seat beam body and be fixed on the chair mounted plate on the seat beam body, the cross-sectional plane of described seat beam body is U-shaped groove structure, both sides at the seat cross-beam body are provided with turnup structure, the two ends of seat beam body are the landing edge structure be connected with vehicle body lower shoe panel beating, described turnup structure and the landing edge structure is smooth-going connects as one.
For reducing the chair mounted knock hole on the seat beam body, on described chair mounted plate, be provided with for the fixing projection welding bolt of seat, have the hole suitable with the projection welding bolt diameter on the seat beam body corresponding with the projection welding bolt position.
For improving the bulk strength of seat beam body, the cross-sectional plane of described seat beam body is the U-shaped structure that A/F is greater than bottom.
The beneficial effects of the utility model: smooth-going the connecting as one of landing edge at two side flangings of seat beam body and two ends, centre does not have hatch frame, also having reduced the stress of opening part when increasing the solder joint of seat beam body own concentrates, strengthen the intensity of seat beam body, improved the collision effect of automobile; Projection welding bolt on described chair mounted plate, to seat, provide fixing in, also, simultaneously as the welding locating point of chair mounted plate, reduce the knock hole structure on the seat beam body, reduce stamping procedure, strengthen seat beam body intensity; The U-shaped cross section of seat beam body A/F is greater than bottom, can effectively strengthen the intensity of crossbeam.
Below with reference to drawings and Examples, the utility model is described in detail.
the accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is explosive view of the present utility model.
the specific embodiment
As Fig. 1, shown in Fig. 2, a kind of automotive seat crossbeam assembly structure, comprise seat beam body 1 and be fixed on the chair mounted plate 2 on seat beam body 1, the cross-sectional plane of described seat beam body 1 is U-shaped groove structure, be provided with turnup structure 11 in the both sides of seat cross-beam body 1, the two ends of seat beam body 1 are the landing edge structure 12 be connected with vehicle body lower shoe panel beating, described turnup structure 11 connects as one with landing edge structure 12 is smooth-going, centre does not have hatch frame, also having reduced the stress of opening part when increasing seat beam body 1 solder joint own concentrates, strengthened the intensity of seat beam body 1, improve the collision effect of automobile, described U-shaped groove structure is the U-shaped structure that A/F is greater than bottom, and this structure can strengthen the intensity of seat beam body 1.
Described chair mounted plate 2 is fixed on seat beam body 1 by the mode of spot welding; On described chair mounted plate 2, be provided with for the fixing projection welding bolt 21 of seat, have the hole 13 suitable with projection welding bolt 21 diameters on the seat beam body 1 corresponding with projection welding bolt 21 positions, this structure is when playing fixedly seat, the welding location is provided can to chair mounted plate 2, reduce the knock hole on seat beam body 1, reduce stamping procedure, strengthen seat beam body 1 intensity.
Claims (4)
1. an automotive seat crossbeam assembly structure, comprise the seat beam body and be fixed on the chair mounted plate on the seat beam body, it is characterized in that: the cross-sectional plane of described seat beam body is U-shaped groove structure, both sides at the seat cross-beam body are provided with turnup structure, the two ends of seat beam body are the landing edge structure be connected with vehicle body lower shoe panel beating, described turnup structure and the landing edge structure is smooth-going connects as one.
2. automotive seat crossbeam assembly structure as claimed in claim 1, it is characterized in that: be provided with on described chair mounted plate for the fixing projection welding bolt of seat, on the seat beam body corresponding with the projection welding bolt position, have the hole suitable with the projection welding bolt diameter.
