[0001] The utility model relates to a front plate reinforcement structure of a light truck cargo box, belonging to the technical field of light truck cargo boxes. Background Art
[0002] As the main carrier for transporting goods, the front panel of a light truck cargo box must have a certain degree of impact resistance. Sudden braking during driving will cause the goods in the cargo box to impact the front panel due to inertia. Therefore, the front panel of the cargo box should have sufficient strength and rigidity to ensure that it will not deform after impact to protect the truck cab and passengers. At present, due to the requirement of reducing weight, the front panel of light trucks mostly adopts thin corrugated board structure (such as Figure 8 、 Figure 9 As shown in the figure, the front panel reinforcement ribs are only welded to the front panel body and are not connected to the car body floor, so the reinforcement ribs do not play their due role; although the front panel reinforcement ribs of some cargo boxes are connected to the cargo box floor, the reinforcement ribs themselves have an unreasonable structure, low strength and rigidity, and are easily deformed after impact.

[0004] To solve this technical problem, the utility model provides a front panel reinforcement structure of a light truck cargo box, comprising a bottom plate front cross beam, a front plate body, a front plate upper frame and a front plate reinforcement rib. The cross section of the front plate reinforcement rib body is a basin-shaped structure, and the two ends of the front plate reinforcement rib are provided with an upper end of the front plate reinforcement rib and a lower end of the front plate reinforcement rib. The bottom of the basin structure is the ventral surface of the basin-shaped section, and the top of the basin structure is provided with a basin-shaped section rim with outward-flashed edges on both sides. The basin-shaped section rim is tightly fitted with the front plate body, and the front plate reinforcement rib, the front plate body and the bottom plate front cross beam are connected together by bolts.
[0005] The two ends of the front plate reinforcement rib are provided with a front plate reinforcement rib gradual deformation transition section, so that the front plate reinforcement rib is closely fitted with the troughs at the two ends of the front plate body.
[0006] The upper end of the front plate reinforcement rib is a variable height basin-shaped cross-section structure, so that the reinforcement rib can fit with the corrugated protrusions and corrugated concave surfaces of the front plate.
[0007] Both sides of the lower end of the front plate reinforcement rib are respectively provided with ear plates extending outwards.
[0008] The ear plate is provided with an oblong hole, and the front plate reinforcement rib, the front plate body and the bottom plate front cross beam are connected together by bolts through the oblong hole.
[0009] The lower end of the front plate reinforcement rib is provided with an oblique cut to prevent the lower end of the front plate reinforcement rib from interfering with the chassis accessories.
[0010] The front panel upper frame and the front panel body are formed separately, and the thickness of the steel plate of the front panel upper frame is slightly thicker than that of the steel plate of the front panel body.
[0011] The upper end of the front plate reinforcement rib is tightly fitted to the upper frame of the front plate and is welded along the fitting surface.
[0012] Basin-shaped cross-section reinforcement bars are provided on the outer sides of the front plate reinforcement bars to improve the bending strength of the front plate reinforcement bars and prevent deformation of the cargo box front plate.
[0013] The front plate reinforcement ribs are formed by blanking and stamping of a die.
[0014] Beneficial effect: The front plate of the utility model has the function of preventing cargo from impacting the cab, which can effectively improve the impact resistance of the front plate of the cargo box, and avoid sudden braking during vehicle driving, which causes the cargo in the cargo box to impact the front plate of the cargo box and the cab due to inertia, causing damage to the truck cab or causing injuries to the driver and passengers.
