[0002] Box trucks typically have long cargo boxes, often reaching 9.6 meters or longer. Forklifts cannot directly unload cargo from these trucks. The traditional method is to use a pallet trolley to transfer goods within the cargo box. However, pallet trolleys have small wheels, resulting in significant stress on the wheels during transport, which can compromise the flatness of the truck bed. Utility Model Content

[0003] The main purpose of this utility model is to propose a box truck loading and unloading system and a box truck, which aims to improve the protection of the box truck by the loading and unloading system, avoid damage to the box truck, and increase the service life of the box truck.

[0004] To achieve the above objectives, the present invention proposes a van loading and unloading system, comprising:

[0005] The floor of the carriage has an installation opening that extends along the length of the carriage.

[0006] A conveying structure, disposed at the mounting opening, the conveying structure being used for transporting goods; and

[0007] A cover plate, which can be detachably installed over the mounting opening.

[0008] In one embodiment, the conveying structure includes a plurality of rollers, which are spaced apart along the length of the carriage.

[0009] In one embodiment, each of the rollers is disposed on two longitudinal beams of the van at both axial ends, and the rollers are rotatable relative to the longitudinal beams.

[0010] In one embodiment, the upper surface of the roller is flush with the upper surface of the carriage floor.

[0011] In one embodiment, the cover plate includes a plurality of independent sub-cover plates, which are arranged sequentially to cover the mounting opening.

[0012] In one embodiment, the length of the sub-cover plate is 0.8m-1.5m along the length of the carriage.

[0013] In one embodiment, the area of ​​the cover plate is larger than the area of ​​the mounting opening, and the upper surface of the cover plate is located above the upper surface of the carriage floor; and / or, the thickness of the cover plate is 2mm-4mm.

[0014] In one embodiment, the cover plate is connected to the carriage floor plate by a bolted fastening structure.

[0015] In one embodiment, the bolt fastening structure includes a first connecting hole on the cover plate, a second connecting hole on the carriage floor plate, a third connecting hole on the longitudinal beam, and a bolt. The third connecting hole is configured as a threaded hole, and the bolt passes through the first connecting hole and the second connecting hole and is fastened to the third connecting hole.

[0016] This utility model also proposes a van, including the aforementioned van loading and unloading system.

[0017] This invention provides a cargo loading and unloading system for box trucks, incorporating a cargo box floor, a conveying structure, and a cover. The cargo box floor has an installation opening extending along the length of the cargo box to the rear door. The conveying structure is located at the installation opening and is used for transporting goods. The cover is detachably installed over the installation opening. Compared to existing methods that use pallet jacks for loading and unloading, this invention utilizes the conveying structure at the installation opening on the cargo box floor, saving manpower and eliminating the need for pallet jacks. This avoids damage to the cargo box floor from pallet jacks, improving the protection of the box truck and extending its service life. It also avoids the need to thicken the cargo box floor to prevent damage from pallet jacks, thus contributing to a lighter cargo box floor and a lighter, lower-cost box truck.

[0030] Box trucks typically have long cargo boxes, often reaching 9.6 meters or longer. Forklifts cannot directly unload cargo from these trucks. The traditional method is to use a pallet trolley to transfer goods within the cargo box. However, pallet trolleys have small wheels, resulting in significant stress on the wheels during transport, which can compromise the flatness of the truck bed.

[0031] To avoid damage to the floor of the truck bed by the oxcart, the thickness of the floor is usually increased significantly, which greatly increases the weight and cost of the vehicle.

[0032] This utility model proposes a loading and unloading system for vans.

[0033] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the cargo loading and unloading system of the van includes a cargo box floor 100, a conveying structure 200, and a cover plate 300. The cargo box floor 100 has an installation opening 110 that extends along the length of the cargo box. The conveying structure 200 is disposed at the installation opening 110 and is used to transport goods. The cover plate 300 is detachably disposed on the installation opening 110.

[0034] Specifically, the van includes a cab and a cargo box, the cargo box having a certain length and width. In one embodiment, the cargo box includes a floor 100, side walls, and a roof, the floor 100, side walls, and roof enclosing a storage space for accommodating goods. Of course, in other embodiments, the cargo box may not include a roof; no specific type of van is limited here.

[0035] An installation opening 110 is provided on the floor 100 of the van, extending through the floor 100 along the vertical direction of the van. In one embodiment, the installation opening 110 extends to the rear door 520 along the length of the van. A conveying structure 200 is provided at the installation opening 110. The conveying structure 200 is used to transport goods into the receiving space during loading and to move goods from the receiving space to the door of the van during unloading, thereby saving manpower. By providing the conveying structure 200 at the installation opening 110, the use of a pallet trolley is avoided, thus preventing damage to the floor 100 from the pallet trolley; it also avoids thickening the floor 100 to ensure the use of a pallet trolley, thereby contributing to the lightweight design of the floor 100 and the lightweight design and low cost of the van.

[0036] The van loading and unloading system also includes a cover plate 300, which is detachably installed over the mounting opening 110. Understandably, when loading and unloading, the conveyor structure 200 is used to move the goods. At this time, the cover plate 300 is removed from the mounting opening 110, exposing the conveyor structure 200 for use. When loading and unloading is not required, the cover plate 300 is placed over the mounting opening 110 to prevent dust, mud, moisture, and other impurities from the outside of the van from entering the cargo space through the mounting opening 110, thus preventing dirt from entering the cargo compartment and avoiding any impact on the goods.

[0037] Understandably, the carriage is equipped with doors, including a tailgate 520 located at the rear of the carriage. The installation opening 110 extends to the tailgate 520, allowing the conveying structure 200 to extend to the tailgate 520, which facilitates loading and unloading of goods from the tailgate 520. In another embodiment, the doors also include side doors located on the side wall of the carriage, and the arrangement of the transport structure also facilitates loading and unloading of goods from the side door location.

[0038] The technical solution of this utility model involves setting up a cargo box floor 100, a conveying structure 200, and a cover plate 300 in a cargo box loading and unloading system. The cargo box floor 100 has an installation opening 110 that extends along the length of the cargo box to the rear door 520. The conveying structure 200 is located at the installation opening 110 and is used for transporting goods. The cover plate 300 is detachably installed over the installation opening 110. Compared to the existing method of using a pallet jack for loading and unloading goods, this utility model provides an installation opening 110 on the cargo box floor 100 and a conveying structure 200 at that opening, utilizing the conveying structure 200 for loading and unloading goods. This saves manpower and avoids the use of a pallet jack, thus preventing damage to the cargo box floor 100 from the pallet jack, improving the protection of the cargo box, and extending the service life of the cargo box. This also avoids the need to thicken the cargo box floor 100 to prevent damage from the oxcart, thus promoting the lightweight design of the cargo box floor 100 and the overall lightweight design and low cost of the van. Furthermore, by providing a removable cover 300 to the installation opening 110, external impurities are prevented from entering the cargo box, thus avoiding contamination of the goods.

[0039] Please see Figure 2 and Figure 3 In an embodiment of this utility model, the conveying structure 200 includes a plurality of rollers 210, which are arranged at intervals along the length of the carriage.

[0040] Specifically, the conveying structure 200 includes a plurality of spaced rollers 210 extending along the width direction of the van and spaced along the length direction of the van. In one embodiment, the distance between two adjacent rollers 210 along the length direction of the van is 150mm-160mm. Of course, the spacing between two rollers 210 can be adjusted according to the needs of the transported goods and is not limited here. Understandably, when goods are placed on the rollers 210, a gentle push will cause the rollers 210 to roll, thereby moving the goods. The arrangement of the rollers 210 not only makes loading and unloading easier but also simplifies the conveying structure 200.

[0041] Of course, in other embodiments, the conveying structure 200 may also include a motor, two spaced rollers, and a conveyor belt wound around the two rollers. The conveyor belt is arranged along the length of the mounting opening 110. The motor is connected to one of the rollers in a drive connection. As the rollers rotate, the conveyor belt rotates, thereby moving the goods on the conveyor belt.

[0042] Please see Figure 3 In the embodiments of this utility model, each roller 210 is respectively provided on the two longitudinal beams 510 of the van, and the roller 210 can rotate relative to the longitudinal beams 510.

[0043] Understandably, to ensure the installation stability of the roller 210 and its load-bearing capacity on the cargo, the roller 210 is installed on the longitudinal beam 510 of the van. Generally, a van has two longitudinal beams 510 spaced apart along the width of the vehicle, and the mounting opening 110 of the floor 100 is located between the two longitudinal beams 510. The roller 210 is connected to the longitudinal beam 510 via two pins; that is, each end of the roller 210 has a pin. One end of the pin is fixedly connected to the longitudinal beam 510, and the other end is rotatably connected to the roller 210, allowing the roller 210 to rotate relative to the pin. This ensures the reliability of the conveyor structure 200.

[0044] Of course, in other embodiments, additional mounting brackets can be provided under the van for mounting the roller 210.

[0045] In this embodiment of the invention, the upper surface of the roller 210 is flush with the upper surface of the carriage floor 100. This flush alignment facilitates the movement of goods between the roller 210 and the carriage floor 100. It is understood that "flush" refers to approximately flush, not absolutely flush. In one embodiment, the height difference between the upper surface of the roller 210 and the upper surface of the carriage floor 100 is within 2 mm.

[0046] Please see Figure 1 In an embodiment of this utility model, the cover plate 300 includes a plurality of independent sub-cover plates 310, which are arranged in sequence to cover the installation opening 110.

[0047] Understandably, to facilitate the use of the conveying structure 200, in one embodiment, the cover plate 300 includes multiple sub-cover plates 310, which are arranged sequentially to cover the installation opening 110. Taking loading and unloading from the tailgate 520 as an example: When unloading, the goods near the tailgate 520 are first unloaded, exposing the sub-cover plate 310 near the tailgate 520. The sub-cover plate 310 near the tailgate 520 is then removed, exposing the roller 210 near the tailgate 520. Goods in the middle of the carriage can then be moved using the roller 210 near the tailgate 520 to save effort. When the goods in the middle of the carriage are unloaded, the sub-cover plate 310 in the middle of the carriage is exposed. After removing this sub-cover plate 310, the roller 210 in the middle of the carriage is exposed. Goods at the head of the carriage can then be moved using the roller 210 in the middle of the carriage and the roller 210 near the tailgate 520.

[0048] During loading, first, cover the rollers 210 at the head of the carriage with the sub-cover 310, and use the rollers 210 in the middle and rear of the carriage to move the goods to the head of the carriage; then cover the rollers 210 in the middle of the carriage with the sub-cover 310, and use the rollers 210 at the rear of the carriage to move the goods to the middle of the carriage; finally, cover the rollers 210 at the rear of the carriage with the sub-cover 310, and place the goods directly at the rear of the carriage. In this way, loading and unloading of goods can be achieved.

[0049] The arrangement of multiple independent sub-covers 310 facilitates the use of the roller 210 and also provides protection for the interior of the carriage, preventing external impurities from entering. In one embodiment, the length of the sub-cover 310 along the length of the carriage is 0.8m-1.5m. In another embodiment, the length of the sub-cover 310 is 1m. Of course, in other embodiments, the length of the sub-cover 310 can also be other values, which are not limited here.

[0050] Please see Figure 4 and Figure 5 In an embodiment of this utility model, the area of ​​the cover plate 300 is larger than the area of ​​the installation opening 110, and the upper surface of the cover plate 300 is located above the upper surface of the carriage floor 100; and / or, the thickness of the cover plate 300 is 2mm-4mm.

[0051] Understandably, in one embodiment, the area of ​​the cover plate 300 is larger than the area of ​​the mounting opening 110. When the cover plate 300 covers the mounting opening 110, at least a portion of the lower surface of the cover plate 300 contacts the upper surface of the carriage floor 100, thereby placing the upper surface of the cover plate 300 above the upper surface of the carriage floor 100. Alternatively, the area of ​​the cover plate 300 may be less than or equal to the area of ​​the mounting opening 110, allowing the cover plate 300 to be embedded within the mounting opening 110. This arrangement ensures that the cover plate 300 completely covers the mounting opening 110, thus preventing external impurities from entering the carriage.

[0052] In one embodiment, the thickness of the cover plate 300 is 2mm-4mm along the height direction of the carriage. This relatively thin thickness of the cover plate 300 minimizes the height difference between the cover plate 300 and the carriage floor 100, thus preventing cargo from bumping or colliding due to the height difference during loading and unloading, and facilitating loading and unloading.

[0053] Please see Figure 4 and Figure 5 In this embodiment of the invention, the cover plate 300 and the carriage floor 100 are connected by a bolt fastening structure 400. Thus, the cover plate 300 and the carriage floor 100 can be detachably connected via the bolt fastening structure 400. In one embodiment, a sub-cover plate 310 is connected to the carriage floor 100 via four sets of bolt fastening structures 400; the number of bolt fastening structures 400 is not limited. Of course, in other embodiments, the cover plate 300 and the carriage floor 100 can also be detachably connected via a snap-fit ​​connection.

[0054] Please see Figure 4 and Figure 5 In an embodiment of this utility model, the bolt locking structure 400 includes a first connecting hole on the cover plate 300, a second connecting hole on the carriage floor 100, a third connecting hole on the longitudinal beam 510, and a bolt. The third connecting hole is configured as a threaded hole, and the bolt passes through the first connecting hole and the second connecting hole and is locked in the third connecting hole.

[0055] Understandably, the roller 210 is mounted on the two longitudinal beams 510, and the position of the first connecting hole of the cover plate 300 corresponds to the position of the longitudinal beam 510. Bolts pass through the first and second connecting holes and are then secured to the longitudinal beam 510. In one embodiment, since it is inconvenient to install nuts at the position of the longitudinal beam 510, the third connecting hole on the longitudinal beam 510 is designed as a threaded hole. After the bolt passes through the first and second connecting holes, it is directly screwed into the third connecting hole to fix the cover plate 300. In one embodiment, the first and second connecting holes are configured as smooth holes.

[0056] This utility model also proposes a van, which includes a van loading and unloading system. The specific structure of the van loading and unloading system is as described in the above embodiments. Since this van adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0057] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
