For example, the "first" information can also be referred to as "second" information without departing from the scope of the present application, and similarly, the "second" information can also be referred to as "first" information.

[0035] As Figures 1 to 7In the description of the present application, the front-rear direction refers to the length direction of the vehicle body, and the front direction is the vehicle head direction and the rear direction is the vehicle tail direction. The preferred embodiment of the vehicle body side frame of the present application comprises a longitudinal beam assembly 1, a door frame skeleton 2, a cargo box skeleton 3 and a reinforcing member 4, the longitudinal beam assembly 1 comprises a longitudinal beam front section 11, a longitudinal beam middle section 12 and a longitudinal beam rear section 13; the door frame skeleton 2 is annular, and the door frame skeleton 2 is fixed on the longitudinal beam middle section; the cargo box skeleton 3 is fixed on the longitudinal beam rear section 13, and the cargo box skeleton 3 is fixed with the door frame skeleton 2, and the cargo box skeleton 3 and the longitudinal beam rear section 13 form a first annular structure; the front end of the reinforcing member 4 is fixed with the longitudinal beam front section 11, and the rear end of the reinforcing member 4 extends upward and rearward and is fixed with the middle part of the front end of the door frame skeleton 2, and the reinforcing member 4, the longitudinal beam front section 11 and the front end of the door frame skeleton 2 form a second annular structure. The second annular structure, the door frame skeleton 2 and the first annular structure constitute three annular force transmission structures fixed in sequence from front to rear, which enhances the overall load-bearing capacity and impact resistance of the vehicle body and improves the safety of the vehicle body.

[0036] In the embodiment, the longitudinal beam assembly 1 is formed by separate processing and assembly, and the longitudinal beam front section 11, the longitudinal beam middle section 12 and the longitudinal beam rear section 13 are connected in sequence; the connection methods of the longitudinal beam front section 11, the longitudinal beam middle section 12 and the longitudinal beam rear section 13 include welding, riveting and bolt connection. The cargo box skeleton 3 comprises a front reinforcing column 31 and a rear skeleton 32 fixed on the rear end of the front reinforcing column 31, and the rear skeleton 32 is fixed with the longitudinal beam rear section 13; the front reinforcing column 31 comprises a vertical section 311 and a horizontal section 312 fixed on the lower end of the vertical section 311; the vertical section 311 is fixed with the door frame skeleton 2, the front end of the rear skeleton 32 is fixed with the middle part of the vertical section 311, the rear end of the rear skeleton 32 is fixed with the longitudinal beam rear section 13, and the horizontal section 312 is fixed with the longitudinal beam rear section 13; the longitudinal beam rear section 13, the rear skeleton 32 and the front reinforcing column 31 enclose a first annular structure. The vertical section 311 and the horizontal section 312 are arranged in an L shape, and the contact area between the horizontal section and the longitudinal beam middle section 12 is large, which improves the connection firmness of the longitudinal beam middle section 12 and the horizontal section 312.

[0037] Specifically, the door frame skeleton 2 comprises a front side plate 21, a bottom plate 22, a rear side plate 23 and a top plate 24 connected in sequence to form an annular structure, and the front side plate 21, the bottom plate 22, the rear side plate 23 and the top plate 24 are fixedly connected by welding, and the bottom plate 22 is fixed on the longitudinal beam middle section 12. In other embodiments of the present application, the door frame skeleton 2 can be processed by integral molding. The front reinforcing column 31 is fixedly connected with the rear side plate 23, and the fixedly connected front reinforcing column 31 and the rear side plate 23 form a vehicle body B column, and the fixed connection of the front reinforcing column 31 and the rear side plate 23 not only fixes the cargo box skeleton 3 with the cab, but also forms a vertical double column structure with the vertical section 311 and the rear side plate 23, which ensures the strength of the vehicle body B column and enhances the strength of the vehicle body B column.

[0038] In order to facilitate mass processing, in the embodiment, the front reinforcing column 31 is a plate body, so that the front reinforcing column 31 can be made by stamping the plate. The thickness direction of the front reinforcing column 31 is along the width direction of the vehicle body, and the width of the front reinforcing column 31 is along the length direction of the vehicle body. In this way, the front reinforcing column 31 made of the plate body can withstand greater impact force in the front-rear direction, and further improve the safety of the vehicle body.

[0039] In order to ensure the firm connection between the front reinforcing column 31 and the rear section 13 of the longitudinal beam, in the embodiment, the vehicle body side wall further comprises a first connecting piece 51, the first connecting piece 51 has a horizontally arranged first connecting portion 511 and a vertically arranged second connecting portion 512, and a reinforcing portion 513 arranged between the first connecting portion 511 and the second connecting portion 512; the first connecting portion 511 is fixed with the upper end of the rear section 13 of the longitudinal beam, and the second connecting portion 512 is fixed with the rear end of the horizontal section 312. Specifically, the upper end mounting surface of the upper end of the rear section 13 of the longitudinal beam is a horizontal surface. If the first connecting piece 51 is not arranged, the connection strength between the vertically arranged plate body used as the front reinforcing column 31 and the horizontally arranged end surface is low. In the embodiment, after the first connecting piece 51 is arranged, the thickness direction of the plate body is attached to the vertical section of the connecting piece, and the connection strength between the plate body and the connecting piece is high, thereby ensuring the firm connection between the front reinforcing column 31 and the rear section 13 of the longitudinal beam. Specifically, the first connecting piece 51 is made by stamping a metal plate, and a reinforcing rib is arranged at the corner between the first connecting portion 511 and the second connecting portion 512 to form the reinforcing portion 513. The first connecting portion 511 and the horizontal section 312, and the second connecting portion 512 and the rear section 13 of the longitudinal beam can be fixedly connected by fastening, riveting or welding.

[0040] In the embodiment, the top plate 24 comprises a first connecting section 241 connected with the front side plate 21 and a second connecting section 242 connected with the rear side plate 23, the first connecting section 241 is arranged in an up-down inclined manner with the front end lower and the rear end higher, and the absolute value of the difference between the inclination angle of the reinforcing member 4 and the inclination angle of the first connecting section 241 is less than or equal to 20° and greater than or equal to 5°. When the front section 11 of the longitudinal beam is subjected to a rearward impact force, the impact force applied by the reinforcing member 4 to the front side plate 21 can be in the same direction as the inclination direction of the reinforcing section, the difference between the inclination angle of the reinforcing member 4 and the inclination angle of the first connecting section 241 is small, which can make the impact force transmitted to the first connecting section 241, reduce the bending moment suffered by the front side plate 21, avoid the front side plate 21 as the A-pillar of the vehicle body from collapsing into the cab, and ensure the safety of the personnel in the cab. In the case where the connection position of the reinforcing member 4 and the front section 11 of the longitudinal beam is unchanged, increasing the inclination angle of the reinforcing member 4 can reduce the difference between the inclination angle of the reinforcing member 4 and the inclination angle of the first connecting section 241, and the inclination angle of the reinforcing member 4 being too large will result in the installation space occupied by the reinforcing member being increased, which is not conducive to the arrangement of the components in front of the vehicle. Therefore, while increasing the inclination angle of the reinforcing member 4, the connection position of the reinforcing member 4 and the front section 11 of the longitudinal beam needs to be moved backward, which will result in the size of the second ring structure being reduced, which is not conducive to force transmission. In the embodiment, the absolute value of the difference between the inclination angle of the reinforcing member 4 and the inclination angle of the first connecting section 241 is less than or equal to 20° and greater than or equal to 5°, which not only ensures that the size of the second ring structure is appropriate, thereby ensuring the force transmission effect, but also facilitates the arrangement of the components in front of the vehicle.

[0041] The middle section 12 of the longitudinal beam is mainly used for carrying the cab, in order to make the overall center of gravity of the wheels lower, thereby providing stability of the vehicle, in the embodiment, the rear section 13 of the longitudinal beam is higher than the middle section 12 of the longitudinal beam, the rear section 13 of the longitudinal beam is mainly used for carrying the cargo compartment, the front end of the horizontal section 312 is fixed to the lower end of the vertical section 311, the rear end of the horizontal section 312 is fixed to the front end of the rear section 13 of the longitudinal beam, and the horizontal section 312 is arranged in an up-down spaced-apart manner with the middle section 12 of the longitudinal beam, the horizontal section 312 and the middle section 12 of the longitudinal beam are arranged in an up-down parallel spaced-apart manner, when force is transmitted in the front-rear direction, the horizontal section 312 and the middle section 12 of the longitudinal beam simultaneously transmit force to the rear section 13 of the longitudinal beam, and the horizontal section 312 and the middle section 12 of the longitudinal beam are respectively located at the upper part and the lower part of the rear section 13 of the longitudinal beam, which avoids a large bending moment at the connection position of the middle section 12 of the longitudinal beam and the rear section 13 of the longitudinal beam when force is transmitted in the front-rear direction, and further improves the bending and torsional strength of the vehicle body side at the junction of the cab and the cargo compartment.

[0042] To facilitate the transition between the middle section 12 and the rear section 13 of the longitudinal beam, in the embodiment, the longitudinal beam assembly 1 further comprises a transition section 14 arranged between the middle section 12 and the rear section 13 of the longitudinal beam, the transition section 14 is arranged obliquely upward and downward, the front end of the transition section 14 is lower and the rear end is higher, the front end of the transition section 14 is fixed to the rear end of the middle section 12, and the rear end of the transition section 14 is fixed to the front end of the rear section 13 of the longitudinal beam.

The force transmission section 112 can disperse the impact force in the front-rear direction received by the front axle mounting section 111 to the reinforcing member 4 and the middle section 12 of the longitudinal beam, avoiding the middle section 12 of the longitudinal beam or the door frame skeleton 2 from bearing all the impact alone, thereby further improving the overall strength and impact resistance of the body side of the vehicle body of the embodiment.
