Abstract
The utility model discloses a car roof cross beam and a car. The car roof cross beam comprises a cross beam body welded on a car body. The cross beam body comprises a V-shaped support beam and a vertical support beam. The sharp end of the V-shaped support beam is connected with one end of the vertical support beam. The V-shaped support beam and the vertical support beam are integrally formed. Welding spots are arranged on the end portion, far away from the connection end, of the V-shaped support beam and the end portion, far away from the connection end, of the vertical support beam respectively. According to the car roof cross beam and the car, due to the fact that the cross beam body is connected with the car body in a three-point mode rather than a traditional two-point mode, the overall structural stability and reliability are improved.

Wherein, the close side wall assembly place of described V-type strutbeam is provided with the vertical section perpendicular to this side wall assembly.
Wherein, described V-type strutbeam and allotment beam include bearing flat plate and the reinforced rib of being located at these bearing flat plate both sides.
Wherein, described reinforced rib is provided with coating groove.
Wherein, described bearing flat plate is provided with lightening hole.
For solving the problems of the technologies described above, embodiment of the present utility model also provides a kind of vehicle, comprise car body, be spaced on the described car body and be provided with such as front each described automobile roof beam, the allotment beam of the V-type strutbeam of described cross-beam body and adjacent described cross-beam body is located at the same side of described car body.
A kind of automobile roof beam and vehicle that the utility model embodiment provides have the following advantages when being applied in the body structure:
(1) application of the present utility model has reduced the quantity of the full-sized car top cover outside plate center member bodies such as MPV, SUV, effectively reduces cost;
(2) it can Effective Raise top cover pressure resistance;
(3) it can improve vehicle side impact performance;
(4) it has effectively reduced welding sequence, has saved man-hour.

The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The problem that the utility model is poor for existing roof panel cross member pressure resistance and productive costs is high provides a kind of automobile roof beam and mounting structure thereof.
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of automobile roof beam, comprise the cross-beam body 2 that is welded on the car body, described cross-beam body 2 is positioned at the below of top cover outside plate 1, described cross-beam body 2 comprises V-type strutbeam 9 and allotment beam 10, the tip of described V-type strutbeam 9 connects an end of described allotment beam 10, described V-type strutbeam 9 and allotment beam 10 are formed in one, described V-type strutbeam 9 and allotment beam 10 are respectively equipped with solder joint 4 away from the end of coupling end, described cross-beam body 2 only need weld three ends totally 6 solder joints 4 when welding with top cover outside plate 1, and traditional roof panel cross member will reach same effect, need to arrange two roof panel cross members, need to weld four ends totally 8 solder joints during welding, the minimizing of solder joint, effectively reduce weld time, improved production efficiency.Described V-type strutbeam 9 close side wall assembly 3 places are provided with the vertical section perpendicular to this side wall assembly 3.
As shown in Figure 1, described V-type strutbeam 9 and allotment beam 10 include bearing flat plate 7 and the reinforced rib 8 of being located at these bearing flat plate 7 both sides.Described reinforced rib 8 is provided with coating groove 6.Described bearing flat plate 7 is provided with lightening hole 5, when not reducing structural strength, has alleviated weight, has practicality.
As shown in Figure 4, during for top cover outside plate 1 pressurized, cross-beam body 2 suffered impulsive forces can conduct along three directions, effectively impulsive force are spread out, and have increased the ability to bear of top cover outside plate 1, have improved the safety when rolling occurs vehicle.
As shown in Figure 5, when vehicle is subject to side impact, the main collision prevention girders absorption collision energy that relies in car body B post and the car door, and car body B post is when being subject to clashing into, need to up and down both direction conduction of Impact energy, when Impact energy conducts to the cross-beam body 2 of car body top, the both direction of energy along V-type strutbeam 9 can be conducted again, effectively reduce Impact energy, improve side collision performance.
As shown in Figure 6, for three cars that do not have the B post, owing to lacking the B post, for improving the side impact performance, the intensity of top cover and energy dispersal performance are then particularly important.When vehicle was subject to side impact, collision energy conducted to cross-beam body 2 by side door, and energy conducts again along the both direction of V-type strutbeam 9, effectively reduces Impact energy, improved without B post vehicle side impact resistant capability.
As shown in Figure 7, the utility model embodiment also provides a kind of vehicle, comprise car body, described cross-beam body 2 is spaced to be located on the described car body, and the allotment beam 10 of the V-type strutbeam 9 of described cross-beam body 2 and adjacent described cross-beam body 2 is located at the same side of described car body.Adopt the arrangement of above-mentioned cross-beam body 2 can effectively reduce the quantity of cross-beam body 2, reduce solder joint, reduce weld time, raise the efficiency." Y " type structural reinforcing that V-type strutbeam 9 and allotment beam 10 forms the pressure resistance of top cover outside plate, improved simultaneously car body strength.For large-scale SUV, MPV and este wagon etc., because car body is longer, so the length of top cover outside plate 1 is also longer, layout had both improved the rigidity of car body top like this, improved again the pressure resistance of top cover outside plate 1.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
