Description

Technical Field

[0001] This utility model relates to the technical field of freight vehicle components, specifically to a novel freight vehicle body. Background Technology

[0002] The existing carriages generally use a rigid coupling method of welding or bolting to connect the side panels, columns, and floor. This structure makes the various components of the carriage form an integral frame that cannot be disassembled, resulting in the permanent fixation of the carriage's spatial form and function. Once manufactured, the opening angle of its side panels, the position of its columns, and the height of its body cannot be dynamically adjusted according to changes in cargo size, loading and unloading methods, or transportation scenarios, essentially depriving the carriage of its adaptability and reconfigurability. Utility Model Content

[0003] This utility model proposes a new type of carriage, which solves the problem that the fixed structure between the side panels, columns and floor of the existing carriage can no longer meet the dynamic needs of modern logistics for flexible and modular transportation vehicles.

[0004] The technical solution of this utility model is implemented as follows:

[0005] The new type of carriage includes a carriage floor, multiple uprights detachably disposed on the outer periphery of the carriage floor, and side panels hinged to the sides of the carriage floor; wherein, the side panels and the carriage floor are hinged at an adjustable angle through a separable rotating connection mechanism; the uprights and the carriage floor are detachably fixed through a vertical insertion positioning mechanism; and a dynamically lockable plug-in linkage component is provided between the side panels and the uprights, which selectively locks the lateral displacement of the side panels through a liftable locking pin structure.

[0006] Furthermore, the separable rotating connection mechanism includes an open suspension hook located on the side of the carriage floor and a rotating shaft located at the bottom of the side plate, wherein the rotating shaft is rotatably fitted into the open opening of the suspension hook.

[0007] Furthermore, the vertical insertion positioning mechanism includes a support plate fixed to the floor of the carriage, and the bottom of the column is adapted to the support plate.

[0008] Furthermore, the support plate is provided with a positioning socket, and the bottom of the column is provided with a shaft, which is adapted to be inserted into the positioning socket to achieve radial positioning.

[0009] Furthermore, the vertical insertion positioning mechanism also includes a fixing ring / frame a on the support plate and a fixing shaft a in the column, wherein the fixing shaft a is axially inserted into the fixing ring / frame a to achieve axial fixation.

[0010] Furthermore, the dynamically lockable plug-in linkage component includes a fixed ring / frame b located on the side of the side plate and a fixed shaft b located inside the column that can move linearly up and down.

[0011] When the fixing ring / frame b is flipped up to be above the fixing shaft b via the side plate, the fixing shaft b is driven to rise and insert the fixing ring / frame b to achieve lateral locking between the side plate and the column.

[0012] Furthermore, the column is provided with a driving component, which is a component that converts its rotational motion into linear motion about a fixed axis b.

[0013] Furthermore, the side of the column is provided with a retaining edge extending into the carriage to limit excessive swaying of the side plate towards the carriage floor.

[0014] Furthermore, the side plate adopts a modular splicing structure, with a slot on one side and a rib on the other side. The height of adjacent side plates is extended by inserting the rib into the slot.

[0015] The beneficial effects of the technical solution provided in this application are as follows:

[0016] 1. This new type of carriage features a detachable rotating connection mechanism that decouples the rigid constraints between the side plates and the carriage floor, giving the side plates dynamic adaptability with two-way degrees of freedom: it retains the rotational freedom of the hinged structure to achieve stepless adjustment of the opening and closing angle, while the detachable design allows the side plates to be quickly removed from the side of the floor at any time. This completely eliminates the risk of stress concentration and fracture of traditional welded hinges, enabling the carriage to instantly switch from a closed box-type form to a flatbed transport mode, adapting to the sudden needs of loading and unloading irregular goods;

[0017] 2. This new type of carriage features a vertical plug-in positioning mechanism that reconstructs the mechanical transmission path between the columns and the carriage floor using a modular plug-in paradigm. The bottom of the columns achieves both radial and axial bidirectional constraints through plug-in components, ensuring load-bearing stability and reducing the disassembly and assembly of a single column to within 10 seconds. The problems of localized deformation, corrosion, and jamming caused by bolted connections in traditional carriages are fundamentally solved. The column layout can be dynamically reconfigured according to cargo stacking requirements, releasing the flexible potential of carriage space planning.

[0018] 3. This new type of carriage features a dynamic locking linkage component that creatively transforms the mechanical linkage between the side panels and the columns into an intelligent locking system that is triggered on demand. By selectively locking the lateral displacement of the side panels through lifting locking pins, a rigid anti-torsional frame is constructed during carriage transportation, and the constraints are released with a single click during loading and unloading of goods, freeing the side panels from flipping.

Detailed Implementation

[0025] 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.

[0026] In existing technologies, the rigid coupling of components such as side panels and columns in the carriage results in a fixed function and an inability to dynamically adapt to needs. This technical solution is a new type of carriage that has the advantage of dynamic adjustment compared to existing carriages. It improves the shortcomings of the rigid coupling and unadjustable nature of traditional carriage components by using a modular approach.

[0027] Reference Figure 1-3This embodiment discloses a novel carriage. The overall structure of the carriage includes a carriage floor 10 and multiple detachable columns 30 arranged around the outer perimeter of the carriage floor 10. By using a modular plug-in design between the columns 30 and the carriage floor 10, the columns can be used for plug-and-play load-bearing and instantaneous removal, completely breaking the fixed layout constraints of traditional carriage frames. Furthermore, the carriage floor 10 has detachable hinged side panels 20. This detachable connection decouples the rigid connection between the side panels 20 and the carriage floor 10, giving the side panels the dual functions of free rotation and rapid separation. This allows the side panels to dynamically adjust their opening angle or be completely removed according to cargo loading and unloading requirements. In addition, the side panels 20 and the columns 30 can be dynamically locked by plugging in. Using a selective lateral displacement locking mechanism with a liftable locking pin, a rigid linkage between the side panels 20 and the columns 30 is established during transportation. During loading and unloading operations, the constraints are released with a single click, freeing up operational freedom and fundamentally resolving the technical contradiction of switching between rigid and flexible carriage forms.

[0028] The connection between the upright 30 and the carriage floor 10 is as follows: a support plate 12 is provided on the carriage floor 10 at the position corresponding to the detachable upright 30, and the bottom of the detachable upright 30 is adapted to the support plate 12. Through the adaptive contact between its load-bearing structure and the bottom of the upright, a vertically downward mechanical support reference surface is provided for the upright 30. At the same time, the rigidity of the plate is used to distribute the local pressure applied by the upright, avoiding deformation of the carriage floor 10 due to concentrated load, thus fundamentally ensuring the static stability of the upright 30 under load. When the bottom of the upright 30 is placed vertically on the support plate 12, the self-weight of the upright 30 and the cargo load are evenly transferred to the load-bearing plane of the support plate 12 through the bottom end face; the support plate 12 disperses the pressure it receives to the adjacent area of ​​the carriage floor 10, and the point impact of the upright 30 on the floor is offset by the surface contact stress diffusion effect, so that the upright 30 maintains its initial positioning state without the intervention of additional fasteners, providing basic positioning conditions for subsequent rapid disassembly and assembly.

[0029] Furthermore, the support plate 12 is provided with a fixing ring / frame a 13, and the detachable column 30 is provided with a fixing shaft a 34 for inserting the fixing ring / frame a 13. The fixing ring / frame a 13 and the fixing shaft a 34 constitute an axial pull-out restraint unit: the fixing ring / frame a 13 fixed to the support plate 12 provides a vertical limiting window through its annular / frame structure, and when the fixing shaft a 34 inside the column 30 is axially inserted into the window, it forms a rigid mechanical stop against the upward displacement of the column 30, eliminating the risk of the column detaching from the carriage floor 10 under bumpy conditions. When the fixed shaft a 34 at the bottom of the column 30 is vertically inserted into the inner hole of the fixed ring / frame a 13 of the support plate 12, the outer circumferential surface of the fixed shaft a 34 and the inner wall of the fixed ring / frame a 13 form an axial constraint interface with full circumferential contact. This interface transmits the upward impact force on the column 30 to the fixed ring / frame a 13 through the shoulder of the fixed shaft a 34, and then disperses it to the carriage floor 10 by the support plate 12, thereby achieving unidirectional rigid locking of the axial displacement of the column 30.

[0030] Furthermore, the support plate 12 has a socket 13, and the detachable column 30 has a shaft 35 that is inserted into the socket 13 for positioning. When the fixed shaft a 34 at the bottom of the column 30 is vertically inserted into the inner hole of the fixing ring / frame a 13 of the support plate 12, the outer circumferential surface of the fixed shaft a 34 and the inner wall of the fixing ring / frame a 13 form a fully circumferential contact axial constraint interface; this interface transmits the upward impact force on the column 30 through the shoulder of the fixed shaft a 34 to the fixing ring / frame a 13, and then disperses it to the carriage floor 10 by the support plate 12, thereby achieving unidirectional rigid locking of the axial displacement of the column 30. When the insertion shaft 35 is inserted into the socket 13 in a vertical direction, the outer surface of the insertion shaft 35 and the inner wall of the socket 13 generate a circumferential tangential contact force; this contact force generates a uniformly distributed radial reaction force in the horizontal plane, which directly offsets the lateral impact load on the column 30, so that the column 30 maintains a precise radial positioning state without welding or bolt fastening.

[0031] The connection between the side plate 20 and the carriage floor 10 is as follows: the side of the carriage floor 10 is provided with an open suspension hook 11, and the bottom of the side plate 20 is provided with a shaft-like component 21 that rotates circumferentially along the open suspension hook 11. The open suspension hook 11 on the side of the carriage floor 10 provides an unclosed arc track through its C-shaped open structure, and the shaft-like component 21 at the bottom of the side plate 20 slides circumferentially along the track to adjust the opening and closing angle of the side plate 20. At the same time, the shaft-like component 21 can be disengaged from the suspension hook 11 at any time by utilizing the disengagement path of the open opening, giving the side plate 20 the ability to quickly separate from the carriage floor 10. When the shaft component 21 is fitted into the arc groove of the open suspension hook 11, the outer peripheral surface of the shaft component 21 and the inner wall of the suspension hook 11 form a rotating guide surface in continuous contact, allowing the side plate 20 to rotate freely around the center of the shaft component 21; when the side plate 20 is raised to a certain height, the shaft component 21 moves radially out along the open side notch of the suspension hook 11, instantly releasing the mechanical coupling between the side plate 20 and the car floor 10.

[0032] The connection between the side plate 20 and the column 30 is as follows: the side of the side plate 20 has a fixing ring / frame b 22 extending into the column 30, and the column 30 has a fixing shaft b 33 that can be inserted into the fixing ring / frame b 22; the vertical displacement of the fixing shaft b 33 is specifically achieved by the action of a driving component 32. The driving component 32 here is the same as the traditional side panel buckle structure used on trucks, except that the buckle is replaced by a fixing shaft b 33. The structure of the side panel buckle is conventional technology and will not be described in detail here. The fixing ring / frame b 22 on the side of the side plate 20 extends into the interior of the column 30 to form a locking window, and the fixing shaft b 33 driven by the linear clamp 32 is inserted axially into this window, innovatively transforming the traditional buckle locking principle of the side panel buckle into an axial circumferential constraint, realizing the rigid connection and instantaneous decoupling between the side plate 20 and the column 30. When the linear clamp 32 pushes the fixed shaft b 33 upward, the column of the fixed shaft b 33 extends into the inner hole of the fixed ring / frame b 22, forming a mechanical interlock interface, analogous to the engagement state of a side panel buckle. However, unlike the side panel buckle, which achieves this by physically restricting the lateral displacement of the side plate 20, the side panel buckle achieves this through pressure coupling between the buckle and the hook. When the linear clamp 32 pulls the fixed shaft b 33 downward, disengaging it from the fixed ring / frame b 22, this interface immediately disengages, analogous to the opening of a side panel buckle, releasing the freedom of the side plate 20.

[0033] Additionally, a flange 31 extends from the side of the column 30 to limit the side of the side plate 20 from continuously swinging towards the carriage floor 10. The flange 31 extending from the side of the column 30 provides a rigid mechanical limit for the closing movement of the side plate 20 by physically extending inwards towards the carriage. Its core function is to precisely intercept the continuous swing of the side plate 20 towards the carriage floor 10, preventing the side plate from excessively tilting inwards and impacting the carriage floor or cargo due to gravity or external impact. Simultaneously, it ensures that the side plate 20 forms a stable vertical connection with the column 30 in the closed state, establishing a reliable spatial reference for the dynamic locking of subsequent plug-in linkage components. When the side plate 20 rotates inwards around the rotating shaft 21 to the vertically closed position, its inner edge contacts and collides with the extended surface of the flange 31. The flange 31, through its structural strength, provides instantaneous dynamic buffering and rigid stopping for the side plate 20. The contact interface converts the swing kinetic energy of the side plate 20 into the deformation resistance of the side plate 31, and disperses the load through the frame structure of the column 30, thereby forcibly terminating the swing stroke of the side plate 20 without additional locking devices, ensuring that the side plate 20 is accurately parked at the preset working angle.

[0034] also, Figure 4 As shown, the side panel 20 itself can also be modularly disassembled or combined according to the height requirements of the goods. Specifically, one side of the side panel 20 has a slot 24, and the other side has a rib 23. The combination of the rib 23 and the slot 24 can realize the combination or disassembly of multiple side panels 20. The slot 24 and the rib 23 designed on the side edge of the side panel 20 form a modular expansion interface, and the side panels can be freely combined laterally and instantly decoupled through anti-detachment mechanical interlocking. This structure gives the side panel 20 the ability to dynamically reconfigure according to the stacking height of the goods—a single side panel can be embedded into the slot 24 of another side panel through the rib 23 to achieve stepless vertical stacking, expanding the height of the carriage enclosure from a single layer to multiple layers; conversely, the basic height can be quickly restored through reverse extraction. Its core value lies in breaking the defects of the traditional fixed size of side panels, realizing the flexible reshaping of the carriage space form through the standardization of physical interfaces, and completing the instantaneous switching between heavy transportation and light delivery scenarios without auxiliary tools. The rib 23 and the slot 24 are anti-detachment designs, including but not limited to T-slots and T-strips. When the ribs 23 of the adjacent side plates 20 slide into the slot 24 along the axial direction, the T-section structure forms a self-locking effect in three-dimensional space—the trapezoidal head of the rib 23 and the inverted trapezoidal cavity of the slot 24 produce a progressive interference fit, forming a dual constraint against lateral shear and vertical dislocation through the normal pressure of the contact surface. This geometric locking mechanism allows the splice joint to convert the load into structural internal force through the meshing interface between the rib 23 and the slot 24 when subjected to lateral impacts from goods, avoiding deformation failure caused by stress concentration at the connection, while ensuring that the multi-layer side plates maintain overall rigidity under bumpy conditions. Its physical stability is equivalent to that of a welded frame but it has dynamic reconfigurability.
