But this improvement is not easy. Not only the car body structure and the frame structure supporting the car body need to be greatly changed, but also the molds, equipment, and design related to the car body structure and the frame structure supporting the car body need to be adjusted.
Existing steel or aluminum frame girders will not fit the adjusted body

Embodiment Construction
[0022] In order to facilitate the understanding of the present invention, the following will describe the present invention more fully. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0023] refer to Figure 1-Figure 4 As shown, a frame girder structure provided by the present invention includes two parallel main longitudinal beams 1, several main beams (not shown) vertically connecting the two main longitudinal beams, two parallel supporting longitudinal beams 2, connecting A reinforcing beam 3 at the rear ends of the two supporting longitudinal beams 2 and a plurality of supporting beams 5 parallel to the reinforcing beams 3 . Wherein, the two ends of the main beam are respectively connected and fixed to the two main longitudinal beams 1 , and ar...

The invention provides a car frame girder structure. The car frame girder structure comprises two parallel main longitudinal beams, a plurality of main cross beams vertically connected to the two main longitudinal beams, two parallel supporting longitudinal beams, reinforcing beams connected to the rear ends of the two supporting longitudinal beams, and a plurality of supporting cross beams mutually parallel to the reinforcing beams. The main longitudinal beams comprises the front beam, the connecting beam form by being obliquely bent downwards front the rear end of the front beam, and the rear beam extending horizontally from the rear end of the connecting beam. The supporting longitudinal beams are erected on the main cross beams connected with the front beams and are perpendicular to the main cross beams. The reinforcing beams are perpendicular to the supporting longitudinal beams. The bottoms of the reinforcing beams are erected on the rear beams. The supporting longitudinal beams, the reinforcing beams and the rear beams are wholly in a step shape. The supporting cross beams are erected on the rear beams. The supporting cross beams are located on the sides, away from the supporting longitudinal beams, of the reinforcing beams and distributed in the lengthwise direction of the rear beams in parallel. Compared with the related technologies, the car frame girder structure has the beneficial effects that the car frame girder structure can adapt to an adjusted carriage body, and the car frame strength is ensured.
Description
【Technical field】 [0001] The invention relates to the technical field of vehicles, in particular to a vehicle frame girder structure. 【Background technique】 [0002] With the development of economy and society, trucks are used more and more widely, especially the vans with a box body, which can transport various items in a sealed manner, and have the advantages of flexible maneuvering, convenient operation, high work efficiency, safety and reliability. However, this type of box body is in the shape of a cuboid, and the accommodation space is fixed, so it is difficult to further enhance the accommodation space. If the car body is divided into two parts, the front car and the back car, the junction of the front car part and the back car part forms a stepped shape. As a result, the height of the accommodating goods in the rear compartment is greater than that in the front compartment, and the accommodation space of the compartment can be further improved. But this improvement...
