Specifically, the right and

left side members

12 and 11 may be symmetrically mounted to the vehicle body about a center line of the vehicle extending in the front-rear direction and connected to the front a-pillar and the rear C-pillar, respectively, so that the side members 1 may transmit impact energy from the front end to the rear end or vice versa upon impact, and may be deformed to absorb the impact energy; when the vehicle is impacted, the cross beam 2 can strengthen the strength of the side beam 1 and can also transmit the impact energy of the left side and the right side to each other to balance the vehicle body, so that the vehicle has better impact resistance; the left beam section 21 can extend in a direction substantially perpendicular to the left side beam 11 and is connected with the left side beam 11, the right beam section 22 can extend in a direction substantially perpendicular to the right side beam 12 and is connected with the right side beam 12, the left beam section 21 and the right beam section 22 can be conveniently butted to form a roof frame, and the left beam section 21 and the right beam section 22 are respectively and integrally formed with the left side beam 11 and the right side beam 12, so that the strength and the rigidity of a vertical connection part can be improved, and the overall rigidity and the strength of the roof frame are enhanced, wherein the substantially perpendicular refers to that an included angle between the beam section and the side beam 1 is not necessarily 90 degrees, and can also be about 90 degrees, such as between 85 degrees and 95 degrees; as shown in fig. 7, the joint may be smoothly transitioned to reduce stress concentration and increase impact resistance of the joint; the beam section and the side beam 1 can adopt a thermal expansion forming technology which has a good forming process and high material strength after forming, and other integral forming processes can also be adopted, which are not limited here. In addition, as shown in fig. 2, the side member 1 can extend forward and downward to be connected with the lower reinforcing plate of the a-pillar, so that the front end of the side member 1 can replace the upper half part of the a-pillar, further enhancing the strength and rigidity of the position, reducing the deformation invasion amount when being impacted, and better protecting the safety of people in the cockpit and the copilot.

According to one embodiment of the present disclosure, the left beam section 21 and the right beam section 22 may be detachably connected, as shown in fig. 1.
