Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to a reinforcement support for the cargo box of an automobile chassis. Background Technology

[0002] In the field of vehicle modification, the conventional approach is to add a cargo box support structure to the chassis frame. Existing technologies typically employ complex soft or hard membrane support structures. These structures rely on high-cost molds, with traditional soft / hard membrane processes incurring 50%-70% of the initial mold development cost. This high expense makes the cost per unit too high for small-batch modifications. Therefore, there is an urgent need for a support structure suitable for the needs of the small-batch special-purpose vehicle modification market. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a reinforcement support for the cargo box of an automotive chassis. This support, through a modular topology design and a laser-bending collaborative process, achieves low cost, high production agility, and better meets the needs of the small-batch special-purpose vehicle market. The specific technical solution is as follows: A vehicle chassis frame cargo box reinforcement support includes an inner reinforcing plate and an outer reinforcing plate. The outer reinforcing plate is "door" shaped, with its lower left and right ends turned upwards and welded to the web surface of the main frame. A cargo box support positioning hole and a mounting hole are provided above the outer reinforcing plate. The inner reinforcing plate is "C" shaped, forming a three-sided sealed cavity door structure, and has a welding flange that can be welded to the inner side of the outer reinforcing plate.

[0004] Furthermore, the outer reinforcing plate is made of QSTE420TM-2.9 pickled steel, and the inner reinforcing plate is made of QSTE420TM-2.0 pickled steel.

[0005] Furthermore, the inner and outer reinforcing plates are integrally manufactured through a modular topology design and a laser-bending collaborative process.

[0006] This utility model achieves cargo box support through an internally reinforced and welded structure. Its ingenious structure meets the support requirements of modified vehicle cargo boxes, and its manufacturing process is simple, requiring only low-cost processes such as laser cutting and bending. This meets the customized development needs of the modification market. It is low-cost, highly agile in production, and better suited to the needs of the small-batch special-purpose vehicle market.

[0007] Figure 1 A schematic diagram of the structure of this utility model; Figure 2 Three views of the external reinforcing plate structure of this utility model; Figure 3 Three-view drawing of the internal reinforcing plate structure of this utility model. Detailed Implementation

[0008] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0009] like Figure 1 The diagram illustrates a vehicle chassis cargo box reinforcement support. This support includes an inner reinforcing plate and an outer reinforcing plate. The outer reinforcing plate is U-shaped, with its lower left and right ends turned upwards and welded to the web surface of the chassis body. Cargo box support positioning holes and mounting holes are provided above the outer reinforcing plate. Figure 2 As shown; the inner reinforcing plate is C-shaped, forming a three-sided sealed cavity structure, and has welding flanges that can be welded to the inner side of the outer reinforcing plate, as shown. Figure 3 As shown.

[0010] The outer reinforcing plate is made of QSTE420TM-2.9 pickled steel, and the inner reinforcing plate is made of QSTE420TM-2.0 pickled steel. The inner and outer reinforcing plates are manufactured as a whole through a modular topology design and a laser-bending collaborative process.

[0011] This invention utilizes a modular topology design and a laser-bending collaborative process to achieve cargo box support. Furthermore, the embedded welding structure of inner and outer reinforcing plates provides structural support. It offers low cost, high production agility, and better meets the needs of the small-batch special-purpose vehicle market.

[0012] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
