Description

Technical Field

[0001] This invention relates to the field of truck tailgate technology, and more specifically, to a lightweight truck tailgate based on thermoplastic composite materials and its processing method. Background Art

[0002] Currently, vehicle tailgates are applicable to various vehicle types, including mini-vans, light trucks, and heavy-duty logistics trucks. This has changed the exclusive use and application scope of vehicle-mounted lifting tailgate freight vehicles, making them particularly suitable for loading and unloading multiple, scattered goods and transporting large and medium-sized heavy objects.

[0003] Existing car tailgates are usually made of iron or aluminum alloy. During the production and processing, they are generally welded. Due to their heavy weight, they are prone to deformation during the welding process, making them difficult to process. Moreover, after long-term use, the tailgate is prone to large-scale corrosion, affecting its normal use.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

[0012] The present invention is further configured such that: a plurality of support beams are provided between the connecting beam and the end plate, and the support beams are located between two side beams.

[0013] The present invention is further configured such that: a side plate is provided with a plurality of mounting grooves for inserting support beams, and a limiting plate is provided on one side of the end plate and placed between two side beams, and an embedding groove is provided on the surface of the limiting plate for embedding one end of the support beam.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0030] As shown in the figure, a lightweight truck tailgate based on thermoplastic composite material includes a composite plate 1 and a support frame 2 disposed around the composite plate 1. The composite plate is fixedly connected to the support frame 2 by fasteners (such as bolts).

[0031] The composite board 1 includes an intermediate layer 3, which is specifically a continuous fiber reinforced thermoplastic honeycomb board or other lightweight composite board. An upper aluminum alloy plate 4 is bonded to the upper surface of the intermediate layer 3, and a lower aluminum alloy plate 5 is bonded to its lower surface.

[0032] By using continuous fiber reinforced thermoplastic honeycomb panels or other lightweight composite panels 1 as the intermediate layer 33, the overall weight of the truck tailgate can be effectively reduced, thereby achieving lightweighting and effectively reducing material costs. This replaces the existing tailgates made of multiple metal plates spliced ​​together. At the same time, the support frame 2 ensures the structural strength of the truck tailgate, reduces the assembly process and processing difficulty, and greatly reduces production time costs.

[0033] The thickness of the intermediate layer 3 is 30-40mm, the thickness of the upper aluminum alloy plate 4 is 1.5-3mm, the surface of the upper aluminum alloy plate 4 is provided with wear-resistant patterns to ensure its wear resistance and compressive strength, and the thickness of the lower aluminum alloy plate 5 is 1-3mm.

[0034] The support frame 2 includes a connecting beam 6 connected to the vehicle body. Both ends of the connecting beam 6 are provided with side beams 7 perpendicular to the connecting beam. The ends of the two side beams 7 away from the connecting beam 6 are provided with end plates 8, thereby forming a rectangular profile for installing the composite panel 1, which facilitates installation.

[0035] The connecting beam 6 is U-shaped and includes a base plate 9 and two side plates 10. A horizontal placement plate 11 is provided on the top of the inner wall of one of the side plates 10 facing the end plate 8. A limiting edge 12 is provided on the top of the side plate 10 along its length. The limiting edge 12 and the placement plate 11 form a groove for installing the composite plate. The upper surface of the connecting beam 6 is parallel to the surface of the placement plate 11. The end plate 8 is fixed to the end surfaces of the two connecting beams 6.

[0036] After the support frame 2 is installed, one end of the composite board 1 is placed in the groove and the whole is placed on the surface of the side beam 7. One side of the end plate 8 abuts against the side wall of the composite board 1, thereby ensuring the stability of the composite board 1 after installation.

[0037] Several support beams 13 are provided between the connecting beam 6 and the end plate 8. The support beams 13 are located between the two side beams 7. The support beams 13 provide further support for the composite plate 1 and can further improve the overall structural strength of the tail plate.

[0038] A side plate 10 has several mounting slots 14 for inserting support beams 13. A limiting plate 15 is provided on one side of the end plate 8 between two side beams 7. The surface of the limiting plate 15 has an embedding slot 16 for embedding one end of the support beam 13. After the support frame 2 is installed, one end of the support beam 13 is placed in the mounting slot 14 and the other end is placed in the embedding slot 16 to position and install the support beam 13.

[0039] The top two sides of the mounting groove 14 are provided with positioning grooves 17, and the top two sides of the support beam 13 are provided with positioning blocks 18 inserted into the positioning grooves 17. The positioning blocks 18 are fixedly connected to the bottom of the mounting groove 14 by bolts. The other end of the support beam 13 is fixedly connected to the limiting plate 15 by bolts. The support beam 13 and the support frame 2 are fixed by bolts to ensure their stability after installation.

[0040] Fixing plates 19 are provided on both sides of the support frame 2. The fixing plates 19 are fixedly connected to both sides of the composite board 1 by bolts, with one end placed in the groove and the other end fixedly connected to the side wall of the end plate 8 by bolts, so as to further improve the stability of the composite board 1 after installation.
