Description

Technical Field

[0001] This utility model relates to the technical field of truck body components, specifically to spliced ​​side panels. Background Technology

[0002] Currently, the side panels of freight truck bodies generally adopt an integral welded or bolted structure, and their height is permanently fixed when the vehicle leaves the factory. This rigid connection method means that the side panels cannot be dynamically adjusted according to actual transportation needs: when transporting bulk goods (such as sand, gravel, and grain), excessively high side panels result in material redundancy and increased vehicle weight; while when transporting oversized goods (such as machinery and pipes), the fixed-height side panels cannot be expanded to form effective protection, forcing carriers to replace them with specialized vehicles or install temporary side panels, significantly reducing transportation efficiency and increasing operating costs.

[0003] More importantly, existing side panels lack a standardized splicing structure. Side panels from different vehicle models cannot be interchanged due to inconsistent connection interfaces, requiring the replacement of the entire panel during maintenance. Temporarily added auxiliary panels, lacking a reliable connection mechanism, are prone to displacement or even detachment during vehicle vibrations, posing serious safety hazards. This structural defect essentially hinders the adaptive upgrading of freight vehicles to diverse transportation scenarios. Summary of the Invention

[0004] This utility model proposes a splicing side panel, which solves the problem that the rigid connection method of the side panels of the freight car body in the prior art makes it impossible to dynamically adjust the side panels according to actual transportation needs.

[0005] The technical solution of this utility model is implemented as follows: The splicing side panel includes a panel body, with a first connecting part and a second connecting part respectively provided on opposite sides of the panel body; when two adjacent panels are spliced ​​together, the second connecting part of one panel body and the first connecting part of the other panel body complement each other and are inserted into each other to form a continuous baffle structure.

[0006] Furthermore, the plate body is configured with a hollow cavity, and multiple supporting ribs are provided inside the hollow cavity.

[0007] Furthermore, the thickness of the plate material in the first connecting part and the second connecting part is greater than the thickness of the plate material in the hollow cavity of the plate body.

[0008] Furthermore, the first connecting part includes two symmetrically arranged claws a extending toward the inner side of the plate, and the two claws a together with the side of the plate form a T-shaped groove.

[0009] Furthermore, the second connecting part includes two symmetrically arranged hooks b extending toward the outer side of the plate; the shape of the hooks b is adapted to the T-slot.

[0010] Furthermore, the two hooks b are connected to each other by setting connecting ribs.

[0011] Furthermore, the vertical position of the connecting rib is on the same vertical line as the end of the hook a.

[0012] The beneficial effects of the technical solution provided in this application are as follows: 1. This modular side panel, through the complementary interlocking of the first and second connecting parts, achieves modular dynamic expansion of the freight vehicle side panels for the first time. Transport operators can freely splice multiple side panels according to the height requirements of the cargo: for low-density bulk cargo, the number of splicing layers can be reduced to lower vehicle weight and fuel consumption; for oversized cargo, longitudinal stacking forms a continuous protective structure, completely avoiding the operational costs of replacing dedicated vehicles or temporary reinforcement.

[0013] 2. The interlocking mechanism formed by the complementary plug-in of the spliced ​​side panels creates a synergistic constraint force between adjacent panels during vehicle vibration, resulting in higher resistance to lateral displacement compared to bolt-fixed panels. At the same time, the modular design allows damaged panels to be replaced individually, improving maintenance efficiency and reducing spare parts inventory costs. Attached Figure Description

[0017] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figure 1-3 This embodiment discloses a side panel baffle on the side of a freight vehicle compartment. To address the different side baffle height requirements of various freight vehicle compartments, a connecting structure is provided on the side panel to splice and combine multiple side panels. Specifically, it includes a panel body 10 and a first connecting part 20 and a second connecting part 30 respectively provided on both sides of the panel body 10. The first connecting parts 20 and the second connecting parts 30 of two adjacent panels 10 correspond to each other. During use, the first connecting parts 20 and the second connecting parts 30 are inserted into each other.

[0019] The integrated first connecting part 20 and second connecting part 30 on both sides of the plate 10 form a detachable standardized interface through complementary plugging, allowing multiple plates to be longitudinally expanded and spliced ​​according to the height requirements of the side guards of the freight vehicle: when transporting low-stacking goods, a single layer of plate 10 can meet the protection requirements; when facing over-height goods, the second connecting part 30 is embedded into the first connecting part 20 of the adjacent plate 10 to quickly construct a continuously stacked retaining wall structure, fundamentally replacing the unadjustable defects caused by traditional welding / bolt fixing.

[0020] In addition, to reduce weight, the plate 10 is hollow, and multiple support ribs 12 are provided inside the hollow cavity 11. The support ribs 12 act as a micro-load-bearing skeleton, which transforms concentrated loads into dispersed forces through stress diffusion mechanism. The support ribs 12 suppress local resonance caused by vibration during transportation, so that the weight-reduced plate 10 can still maintain structural integrity under the lateral impact of the cargo, and ultimately achieve the synergistic optimization of "lightweight" and "load-bearing stability".

[0021] Furthermore, to further enhance the stability of the connection between two adjacent plates 10, the thickness of the first connecting portion 20 and the second connecting portion 30 is greater than the thickness of the plate at the hollow cavity of the plate 10. The targeted thickening of the first connecting portion 20 and the second connecting portion 30 maintains the overall lightweight advantage of the plate 10 while forming a reinforced fortress at the stress-concentrated insertion interface: the increased section modulus of the plate significantly improves the shear strength of the hook structure, enhancing the fatigue deformation resistance of adjacent plates 10 against alternating loads during the bumps and vibrations of the freight vehicle, fundamentally preventing splicing loosening and failure due to interface deformation.

[0022] like Figure 3As shown, the anti-detachment component a20 is actually two symmetrically distributed, inwardly positioned hooks a21, which together with the side of the plate 10 form a T-slot 22; the anti-detachment component b30 is actually two symmetrically distributed, outwardly positioned hooks b31. The symmetrically extended hooks a21 and the T-slot 22 formed by the side of the plate 10 provide a high-precision guide rail for the splicing system; while the symmetrically extended hooks b31 serve as dynamic plug-in terminals. Their geometric fit with the T-slot 22 forms a three-dimensional mechanical locking channel between adjacent plates 10: in the horizontal direction, the hook sidewalls hold and restrict lateral movement, while in the vertical direction, the surface contact between the top wall of the T-slot 22 and the back of the hook b31 bears the impact load of the cargo, thus improving the anti-overturning capability of the splicing interface.

[0023] During assembly, the operator inserts the hook b31 into the T-slot 22, and the inner side of the hook a21 and the outer side of the hook b31 form a clamping posture. After assembly, the end of the hook a21 and the groove of the hook b31 form a gravity self-locking. When the truck bumps and the plate 10 is subjected to an upward pulling force, the tendency of the hook b31 to lift up is suppressed by the downward pressure of the end of the hook a21, while the lateral vibration energy is dissipated by the contact friction between the side wall of the T-slot 22 and the hook b31.

[0024] In addition, there are special requirements for the position of the connecting rib 32. The connecting rib 32 is set on the same vertical line at the ends of the two adjacent hooks a21. That is, the ends of hooks a21, the grooves in hooks b31, and the connecting rib 32 are on the same vertical line. The purpose is to ensure that the alternating load generated by the bumping of the freight vehicle is directly introduced from the ends of hooks a21 to the rigid groove anchor point of hooks b31, and then transformed into the cooperative deformation resistance of the two hooks through the lateral support of the connecting rib 32.

[0025] When the impact load of the cargo presses down vertically through the end of the hook a21, the collinear layout triggers a lever-type force transmission mechanism. The pressure at the end of the hook a21 is precisely applied to the force-receiving surface of the groove in the hook b31. The groove converts the vertical pressure into a radial expansion tendency of the hook b31, and the connecting rib 32 immediately generates a reverse constraint torque. This process converts the vibration energy into the elastic potential energy of the connecting rib 32, which is stored and released. This not only prevents the plastic deformation of the hook b31, but also compensates for the fit clearance caused by wear through a dynamic self-tightening effect.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
