DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be described clearly and completely below in combination with the drawings of the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by those skilled in the art belong to the scope of protection of the utility model.

[0029] Embodiment 1

[0030] As Figure 1 shown, an inner clamping type panel structure, comprising a first panel piece 5, a cladding plate piece 6, the cladding plate piece 6 is a bent plate of inverted U type, the cladding plate piece 6 is clamped on both sides of the panel surface of the first panel piece 5, and the first panel piece 5 and the cladding plate piece 6 are connected by multiple welding points, wherein the first panel piece can be a single-layer plate, a composite plate, a frame section bar, etc., by adopting the cladding plate piece 6 of inverted U type bending to clamp the first panel piece, and realizing multiple welding point interval connection between the two, successfully hiding the welding points in the structure, avoiding the problem of exposed welding points under the traditional direct superposition welding mode, thereby significantly improving the overall aesthetic appearance applied to the carriage.

[0031] As Figures 2-5 shown, a tricycle carriage, comprising a bottom plate 1, a fixed panel 2 and a movable panel 3 are installed on the bottom plate, a storage cavity 4 is surrounded between the movable panel, the fixed panel and the bottom plate, the movable panel is hingedly installed on the bottom plate, and a plurality of movable panels are connected, and the movable panel is designed with the above-mentioned inner clamping type panel structure.

[0032] Specifically, the movable panel comprises a tail panel 7 at the tail and side panels 8 at both sides, the tail panel, the side panel and the fixed panel are connected through a lock catch 10, a guardrail part 9 is installed on the top of the side panel, and the guardrail part protrudes from the top of the tail panel, the guardrail part provided on the top of the side panel not only protrudes from the top of the tail panel, but also increases the three-dimensionality and levelness of the carriage, and more importantly, provides additional safety protection for passengers or goods. The design of the guardrail part can effectively prevent passengers or goods from accidentally falling during driving, and improve the overall safety of the carriage; the carriage structure disclosed by the utility model has flexible design, and can be customized and adjusted according to different use requirements. For example, by changing the height, width of the supporting vertical plate and the shape and size of the guardrail part, the requirements of different vehicle models, different loads and different use scenarios can be met.

[0033] Both the side panels and the rear panel include a support plate 13. The upper and lower ends of the support plate are bent outward to form a protrusion 14 and a protrusion 2 15. Support ribs 16 are installed on the outer side of the support plate at the position between the protrusion 1 and the protrusion 2. The support ribs are in the shape of an "I". End clamps 11 are clamped on both sides of the support plate. The end clamps are provided with clamping grooves 12 that match the outer contour of the support plate. The above structure: (1) not only enhances the overall rigidity of the panel, but also provides additional connection points, making the connection between the panels more stable. At the same time, the design of the support ribs further enhances the load-bearing capacity of the support plate, so that the entire car body structure can remain stable when subjected to heavy loads or harsh road conditions. (2) The end clamps clamped on both sides of the support plate and the clamping grooves provided thereon provide precise positioning and fixing for the installation of the covering plate body 6. This design not only simplifies the installation process and improves installation efficiency, but also ensures a tight fit between the cover plate 6 and the supporting upright plate, avoiding problems such as structural loosening or water leakage caused by improper installation.

[0034] Multiple supporting stiffeners 16 are installed at intervals along the length of the side panels and rear panels; in addition, the supporting stiffeners 16 are hollow structures, and the supporting stiffeners are welded to the supporting uprights. The above structure: (1) not only reduces the overall weight of the carriage, but also significantly enhances the bending strength and torsional stiffness of the panels. This design enables the carriage to maintain structural integrity and stability when subjected to heavy loads or complex road conditions, and extends its service life. (2) The hollow structure of the supporting stiffeners can provide better heat conduction and heat dissipation during the welding process, reducing the risk of welding deformation and cracks.

[0035] The first and second protrusions have trapezoidal cross-sections, and the free ends of the bent portions of the supporting uprights are provided with overlapping extensions 17, which are fitted to the outer surface of the supporting uprights. This not only increases the contact area between the panels and improves the stability of the connection, but also allows the panels to better disperse and resist lateral forces. The overlapping extensions further enhance the connection strength between the protrusions and the supporting uprights, ensuring the integrity and reliability of the structure.

[0036] The supporting uprights are equipped with reinforcing ribs 18 along their length, which further enhances the longitudinal load-bearing capacity of the body panels, enabling the body to maintain structural stability and integrity when subjected to longitudinal forces. This design is particularly suitable for tricycle bodies that frequently require long-distance or heavy-load transport.

[0037] The side compartment plate further comprises a cross beam 19 installed above the support vertical plate, and a plurality of connecting rib plates 20 are installed between the support vertical plate and the cross beam, and the connecting rib plates are arranged in position corresponding to the support rib plates; not only the lateral bearing capacity of the compartment plate is enhanced, but also the overall structure of the compartment is more balanced and stable. This design helps to improve the anti-rollover capability and overall safety of the compartment.

[0038] The present compartment structure can flexibly adapt to the needs of different vehicle models, different load capacities and different use scenarios by adjusting the size and layout of structural elements such as support rib plates, protruding parts, reinforcing convex ribs and cross beams. This design makes the compartment structure more scalable and adaptable, providing users with more options and customization space.

[0039] In the present application, unless otherwise explicitly specified and limited, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances by the ordinary skilled in the art.

[0040] The above is the preferred embodiment of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered within the scope of protection of the present application.
