Specific embodiment
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment one of the cap structure of the utility model, as shown in Figure 1 to Figure 3, a kind of roof frame, including horizontal stroke
Beam, longeron and fixing piece.The crossbeam includes main beam 1, and main beam 1 is the curved arc beam that section is Ω shapes, using presser
Skill is made, and avoids 1 both ends of main beam because caused by bending defect the problem of insufficient rigidity, improve automobile reliability and
NVH effects, main beam 1 are hollow structure, reduce the weight of main beam, so as to reduce the weight of vehicle, realize light weight
Change, and have flanging on main beam 1, flanging can strengthen the intensity of main beam 1, make main beam 1 can also while weight is reduced
Guarantee has certain intensity, which is provided with reinforcing plate 11,12, reinforcing plate 11 at the curved arc of main beam 1, with side indulge by main beam 1
Beam 3 is connected in the curved arc port of main beam 1, due to being easily deformed when curved arc is in the stress by entire frame, it is therefore desirable to
Reinforcing plate 1 strengthens the rigidity and bending resistance of junction, and reinforcing plate 12 is in the junction of main beam 1 and main longitudinal grider 4, due to main vertical
Beam 4 is pushed up to be fixed at covering and luggage carrier, it is therefore desirable to set reinforcing plate to improve the overall stiffness of main beam 1 and main longitudinal grider 4.
The crossbeam further includes auxiliary crossbeam 2, and auxiliary crossbeam 2 is common rectangle pipe material, and both ends are also connect with side longeron 3, for assisting leading
Crossbeam 1 can connect other non-bearing beams, such as ceiling light fixing piece 6, auxiliary longeron 5, tail trimmer 7 together with main beam 1.Institute
It states longeron and includes side longeron 3, side longeron 3 uses high-strength steel rectangle pipe material, connect positioned at the both ends of crossbeam and with beam welding,
To strengthen side longeron 3 intensity and bending resistance whole with main beam 1 when being connect with main beam 1 and equipped with reinforcing plate, for propping up
Entire frame is supportted, the centre of longeron is equipped with main longitudinal grider 4 on side, and main longitudinal grider 4 is common rectangle pipe material, for connecting main beam 1
With auxiliary crossbeam 2, main longitudinal grider 4 is being equipped with reinforcing plate with the junction of main beam 1, to strengthen the integral strength with main beam 1.Longeron
3rd, main longitudinal grider 4, auxiliary crossbeam 2 are all rectangle pipe material, are hollow structure inside rectangle pipe material, have achieved the purpose that reduce weight, and
Auxiliary crossbeam 2 and main longitudinal grider 4 have used common section bar, have reduced cost, and side is indulged due to not being important bearing structure
Beam 3 easily deforms, therefore using high-strength for main bearing structure and in marginal position when accident rolling occurs for vehicle
Steel.Auxiliary longeron 5 is arranged between main beam 1 and auxiliary crossbeam 2, is the straight part of U-shaped of bending sheets, is mainly used for carrying tail trimmer 7,
Tail trimmer 7 carries ceiling light fixing piece 6 together with auxiliary crossbeam 2, and ceiling light fixing piece 6 is also the straight part of U-shaped of bending sheets, and ceiling light is fixed
Part 6, due to not being primary load-carrying members, can be processed, this straight part of U-shaped is not with non-bearing crossbeam with general bending sheets
It is only good to process and weight be mitigated, be conducive to light-weighted realization.
The embodiment two of the roof frame of the utility model：The difference lies in the side longeron is held with embodiment one
Carry the rectangle pipe material that longeron and auxiliary crossbeam carry strip hole for side.
The embodiment three of the roof frame of the utility model：The difference lies in the non-bearing is horizontal with embodiment one
