Preferably; In crossbeam of the present invention; Air plate is connected with the second connection location place to form the osed top cavity body structure at first connection location with the air plate brace panel, and wherein said first connection location is between the air plate two ends, and second connection location is positioned at air plate end points place.
Preferably; In crossbeam of the present invention; Said support is connected with the front windshield glass stay bearing plate with the connection location place of air plate brace panel at the front windshield glass stay bearing plate, and said support is connected with the air plate brace panel with the first connection location place of air plate brace panel at air plate, said support is connected with the air plate brace panel between above-mentioned two connection locations.
Preferably, in crossbeam of the present invention, comprise 2 supports.
Preferably, in crossbeam of the present invention, said support is processed by high strength steel.
The present invention also provides a kind of automobile, comprises the crossbeam of above-mentioned any.
Technique effect of the present invention is: beam structure is simple, function is clear and resultant effect is good.The needs of the pedestrian of suitable car, the protection of cyclist's head impact, the while can be satisfied the rigidity requirement of car load mode and passenger safety performance.

The specific embodiment
To combine accompanying drawing to describe the preferred embodiments of the present invention in detail below, identical in the accompanying drawings reference number is represented components identical.
To combine Fig. 1,2a-2b to describe below according to Front Windshield cross sill of the present invention.As shown in the figure, this air regulator cross sill comprises front windshield glass adapter plate 1, front windshield glass stay bearing plate 6, air plate 2, air plate brace panel 8 and support 5a, 5b.Front windshield glass stay bearing plate 6 two ends are connected with glass adapter plate 1 and air plate brace panel 8 respectively, and ventilation brace panel 8 is connected with air plate 2, and support 5a, 5b one end are connected with air plate 2, and the other end is connected with ventilation brace panel 8 or front windshield glass stay bearing plate 6.Connection between the above-mentioned parts preferably forms through welding, and directly punching press forms.
Though have two supports shown in Fig. 1, the present invention does not limit to therewith.Those skilled in the art can be adjusted into its quantity greater or less than 2 according to actual needs.
Link to each other with front windshield glass stay bearing plate 6 with the connection location C place of air plate brace panel 8 though in Fig. 1, support 5a, 5b be shown at front windshield glass stay bearing plate 6, the present invention does not limit to therewith.For example, can support 5a, 5b be adjusted at the F place, between F and C and link to each other with air plate brace panel 8.
Fig. 6 a is the preceding cross sectional drawing of head impact of the Front Windshield cross sill of Fig. 1.Fig. 6 b is the cross sectional drawing behind the head impact of Front Windshield cross sill of Fig. 1.As shown in the figure; When pedestrian head and this zone bump when contacting; The Front Windshield cross sill absorbs the impact energy of coming from the Windshield transmission because the front windshield glass stay bearing plate is main distortion power-absorbing, and deformation can take place the windscreen stay bearing plate; Below front windshield glass, produced simultaneously extra cushion space, thereby reduced impact pedestrian head.
In addition, Front Windshield cross sill according to the present invention can also be protected occupant's safety.Through adjusting air plate brace panel and/or the wall thickness of support and/or the size that material is regulated crew module's intrusion amount, and the while does not influence the distortion of front windshield glass stay bearing plate.If for example air plate brace panel and/or supporting structure are soft partially; The intrusion amount is bigger; Can strengthen the thickness of air plate brace panel and/or timbering material so; Make the thickness of material bring up to 1.2mm from 1mm, and/or adopt the higher high strength steel of ratio of rigidity etc., wherein high strength steel refers to the steel of tensile strength greater than 1200MPa.
Simultaneously, can regulate body stiffness and mode through material and the wall thickness of regulating the air plate brace panel.Wherein body mode is meant the natural vibration characteristic of vehicle body, is the important parameter that influences car load NVH performance.
In sum, according to the present invention,, can when improving some performance, make other performance can not receive too much influence through the functionalized design of front windshield glass stay bearing plate, air plate and air plate brace panel.
In view of these instructions, those of ordinary skill in the art will expect other embodiments of the invention, combination and modification easily.Therefore, when combining above-mentioned explanation and accompanying drawing to read, the present invention only is defined by the claims.
