An embodiment of the present invention provides an automobile frame, refer to fig. 1, the automobile frame includes a lifting beam assembly 10, two longitudinal beams 30 and at least two supporting assemblies 20, the lifting beam assembly 10 is disposed between the two longitudinal beams 30, the inner side of each longitudinal beam 30 is connected with a supporting assembly 20, please refer to fig. 2, the supporting assembly 20 has a supporting region 20a, in the overlooking projection of the automobile frame, the supporting region 20a of the supporting assembly 20 is located between the two longitudinal beams 30, and the width of the lifting beam assembly 10 is smaller than the width between the two longitudinal beams 30, so that the lifting beam assembly 10 can be placed between the two longitudinal beams 30 from above the two longitudinal beams 30; the laterally opposite ends of the lifting beam assembly 10 are supported and fixedly attached to the support areas 20a of the corresponding bolster assemblies 20.

When assembling operation is carried out, all or part of the lifting beam assembly 10 and the lifting device can be pre-assembled together for lifting, or the lifting beam assembly 10 is lifted separately, then the lifting beam assembly is lifted from the upper part of the longitudinal beam 30 and placed between the two longitudinal beams 30 and gradually descends until the lifting beam assembly 10 is contacted with the supporting area 20a and the lifting beam assembly 10 is supported along the vertical direction, so that the lifting beam assembly 10 realizes the positioning of the height position of the vertical direction, and then the lifting beam assembly 10 is fixedly connected with the bearing assembly 20, therefore, the assembly of the lifting beam assembly 10, the lifting device and the longitudinal beams 30 can be facilitated, the labor intensity of personnel is reduced, and the assembly time is saved; each longitudinal beam 30 is connected with a supporting component 20, so that the load borne by the lifting beam component 10 can be uniformly shared to the two longitudinal beams 30, and the reduction of the service life of the automobile frame caused by the deformation of any longitudinal beam 30 due to uneven load distribution is prevented.

The connection between the lifting beam assembly 10, the support assembly 20 and the longitudinal beam 30 can be achieved by welding, riveting or bolting, so that the required strength design requirements can be met.

From the perspective of improving the space utilization rate, the upper parts of the lifting beam assembly 10 and the bearing assembly 20 do not exceed the upper surface of the longitudinal beam 30, and the lower parts of the lifting beam assembly and the bearing assembly are not lower than the lower surface of the longitudinal beam 30, so that the lifting beam assembly and the bearing assembly do not occupy the installation space of other devices in the vehicle, other parts in the vehicle are convenient to arrange, the mounting height of a carriage is favorably reduced, the mass center of the whole vehicle is reduced, and the operation stability and the driving safety of the vehicle are improved.

The minimum distance between the support plates 21 of the two support assemblies 20 is smaller than the minimum distance between the second convex edges 33 of the two longitudinal beams 30; the support area 20a is located on a support plate 21 and the lift beam assembly 10 is supported on the support plate 21. The second convex edge 33 supports the bearing plate 21, so that the load applied to the bearing plate 21 is transmitted to the longitudinal beam 30 and the force contact area with the lifting beam assembly 10 is increased. The attachment of the web 22 to the main beam body 31 increases the contact area between the side beam 30 and the support assembly 20, making the connection between them more secure.

It is understood that the height of the connecting plate 22 in the up-down direction may be equal to the distance between the first convex edge 32 and the second convex edge 33. The first raised edge 32 and the second raised edge 33 can simultaneously block the connecting plate 22 in the up-down direction to counteract the eccentric downward force on the support assembly 20, further improving the stability of the connection.

The longitudinal beam 30 can be formed by a plurality of layers of channel steel with different sizes in an internal and external laminating mode (not shown in the figure), so that the longitudinal beam 30 is convenient for standardized production, and has the advantages of high bending strength, good manufacturability, convenience in part installation and fastening and the like.

It will be appreciated that in order to increase the load carrying capacity of the support assembly 20 to the load to which the lifting beam assembly 10 is subjected, to prevent deformation of the support assembly 20 and to prevent buckling of the two longitudinal beams 30, additional structural aids may be added to increase the structural strength and load carrying capacity of the support assembly 20.

Through two different force transmission paths, the load borne by the lifting beam assembly 10 can be dispersed to more positions on the longitudinal beam 30, the stressed contact area is increased, the bearing capacity is improved, and the fracture and structural deformation of the connecting position are prevented.

The second plate body 52, the connecting plate 22 and the main beam body 31 are connected into a whole through bolts, so that the load is further conveniently transmitted to the longitudinal beam 30, and the rigidity of the whole structure is improved.

It will be appreciated that the angle of inclination between first plate 51 and second plate 52 may be adjusted so that first plate 51 transfers the load through its compression resistance rather than its bending resistance, thereby increasing its load carrying capacity. For example, the first plate 51 and the second plate 52 are substantially perpendicular to each other.
