The first container cross member 11, the second container cross member 12 and the third container cross member 13 are disposed in parallel and evenly distributed. The third cross member 13 of the cargo box is located at the rearmost end of the cargo box frame.

Accordingly, the container stand 20 includes a pair of first stand beams 21, a pair of second stand beams 22, and a pair of D-posts 23. A pair of first vertical beams 21 are located at each end of the first cross member 11 of the cargo box. A pair of second vertical beams 22 are located at each end of the second cross member 12 of the cargo box. A pair of D-posts 23 are located at each end of the third cross member 13 of the cargo box, and the D-posts 23 are located at the rearmost end of the cargo box frame. The upper ends of the first vertical beam 21, the second vertical beam 22 and the D column 23 are fixedly connected with the upper edge beam 30. The lower parts of the first and second upright beams 21 and 22 are each provided to protrude inward of the vehicle body to form a wheel avoiding space.

The connection member 40 includes a pair of first connection members 41, a pair of second connection members 42, and a pair of third connection members 43. The first connector 41 connects the first cross member 11 of the cargo box with the first vertical beam 21.

Meanwhile, because the integral skeleton type frame structure has stronger structural stability, under the condition of meeting the requirements of integral strength and rigidity, four to five cargo box cross beams of the traditional pickup truck are simplified into three cargo box cross beams 10 which are uniformly distributed, and the weight and cost of the pickup truck are further reduced.

In order to further improve the stability of the cargo box skeleton, the cargo box skeleton is further provided with a first reinforcing beam 51 and a second reinforcing beam 52 extending in the longitudinal direction of the vehicle body. In the present application, the first reinforcing beam 51 is fixed to the first connector 41 and the second connector 42 at both ends thereof, and the second reinforcing beam 52 is fixed to the second vertical beam 22 and the D-pillar 23 at both ends thereof.

Because the density of aluminum is only 1/3 of that of steel, the adoption of the container cross beam 10 made of aluminum alloy material can reduce the overall weight of the container framework by about 25%, thereby being beneficial to lightening the weight of a vehicle body and improving the power economy of a pick-up (especially a new energy pick-up). The cargo box cross member 10 is formed using an extrusion process. Compared with the stamping die of steel material parts, the development cost of the extrusion die of aluminum materials is low, and the die input cost of a container framework can be reduced.

As shown in fig. 3 and 4, the cargo box cross member 10 includes an upper wall 101, a lower wall 102, and a pair of side walls 103. The cavity 104 is formed in the container cross beam 10, the reinforcing ribs 105 are arranged in the cavity, the rigidity and the strength of the container cross beam 10 body are enhanced, and the bearing capacity of the container can be improved.
