Abstract
The utility model discloses a kind of vehicle beam structure, it is related to body of a motor car field, it includes body and extends the mating end for being coupled with automobile longitudinal girder from the body both ends, wherein the cross-sectional configuration of the body is circular arc.The beam structure of this semi-circular cross-section of the present utility model, under the conditions of identical weight, the bending resistant section coefficient of its structure is higher than U-shaped section, so as to obtain more preferable NVH performances.
Description
Technical field
The vehicle body field of automobile is the utility model is related to, more particularly to a kind of vehicle beam structure, and with this
The automobile of beam structure.
Background technology
The vehicle body of car is mostly monocoque construction so that it will not only bear passenger, goods and own wt and bring
Bending load, still suffer from due to torsional load caused by Uneven road, the inertial load of vehicle body fore-and-aft direction during acceleration and deceleration,
Inertial centrifugal load during turning, and the shock loading etc. during collision.Therefore, it is higher to body structure rigidity requirement.
Refer to shown in Fig. 1 and Fig. 2, the cross section of car under body beam structure 10 ' is mostly U-shaped at present, with automobile
Plate 20 ' is welded together by solder joint 30 ', and both ends and the chassis runner 1 of the beam structure 10 ' are welded and fixed.
This existing beam structure 10 ' uses U-shaped cross section structure, if its depth of section is too low, can cause the crossbeam
The rigidity of structure 10 ' is relatively low, and under dynamic load effect, the floor 20 ' being connected with the beam structure 10 ' will vibrate
It is larger, cause in-car construct noise higher.
And if lift the depth of section of the beam structure 10 ', car body weight can be increased again, and increasing the crossbeam knot
While the manufacturing cost of structure 10 ', the problem of oil consumption increase can be brought to vehicle again.
Therefore, it is necessory to design a kind of new beam structure, the defects of to overcome in the prior art.
Utility model content
The purpose of this utility model is to provide a kind of new beam structure, its can in the case of equivalent weight,
With more preferable bending stiffness.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of vehicle beam structure, it includes beam body and is used for the mating with automobile longitudinal girder mating positioned at the beam body both ends
End, the beam body include body and bend extension and and fix company parallel with automotive floor panel from the body both sides of the edge
The alar part connect, wherein, the cross-sectional configuration of the body is circular arc.
Further, in the vehicle beam structure provided according to one embodiment of the utility model, the body
Cross-sectional configuration is semicircle.
Further, in the vehicle beam structure provided according to one embodiment of the utility model, the body
Inner side is provided with the support for strengthen rigidity.
Further, in the vehicle beam structure provided according to one embodiment of the utility model, the body
Outside is provided with the support for strengthen rigidity.
The utility model also provides a kind of automobile, and it includes the vehicle beam structure provided in foregoing any technical scheme.
Relative to prior art, the beneficial effects of the utility model are：Vehicle beam structure of the present utility model is using half
Circular cross-section structure so that under the conditions of identical weight, its bending resistant section coefficient is higher than U-shaped section, improves the crossbeam for it
The bending stiffness of structure, so as to obtain more preferable NVH performances.
Brief description of the drawings
Fig. 1 is the common vehicle beam structure top view fixed with automobile longitudinal girder and floor assembling.
Fig. 2 is the cross section structure schematic diagram of vehicle beam structure in the prior art.
Fig. 3 is the cross section structure schematic diagram that vehicle beam structure is provided according to one embodiment of the utility model.
Description of reference numerals in Fig. 1 to Fig. 3 is as follows.

Embodiment
Below with reference to drawings and examples, a kind of technical scheme of vehicle beam structure of the present utility model is made into one
The detailed description of step.
Refer to shown in Fig. 3, which illustrates the vehicle beam structure 10 provided according to one embodiment of the utility model,
With reference to Fig. 1 references, the beam structure 10 includes beam body and is used to match somebody with somebody with what automobile longitudinal girder 1 was coupled positioned at the beam body both ends
Connect end, the beam body includes body 101, and from the both sides of the edge of body 101 bend extension and with automotive floor panel 20
Alar part 102 that is parallel and being fixedly connected, wherein, the cross-sectional configuration of the body 101 is circular arc, the alar part 102 and ground
Plate 20 is welded together by solder joint 30.
Further to increase its bending stiffness, according to the technical solution of the utility model, in different embodiments, institute
Reinforced support can be set in the outside or inner side for stating beam structure 10, depending on concrete mode can be with being actually needed, and is not limited.
Vehicle beam structure of the present utility model uses semi-circular cross-section structure so that its under the conditions of identical weight, its
Bending resistant section coefficient is higher than U-shaped section, improves the bending stiffness of the crossbeam, so as to obtain more preferable NVH performances.
The utility model further provides for a kind of automobile for including aforementioned automotive beam structure.
Technical scope of the present utility model is not limited solely to the content in described above, and those skilled in the art can be
On the premise of not departing from the utility model technological thought, to above-described embodiment carry out many variations and modifications, and these deformation and
Modification all should work as and belong in the scope of the utility model.
