[0046] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0047] The embodiments of the present application provide a lightweight container. In an embodiment of the lightweight container of the present application, referring to Figure 1 , the lightweight container is made of aluminum alloy material and includes a bottom plate assembly 10, a top plate assembly 20, a side plate assembly 30 and a container framework, wherein

[0048] The container framework includes an upper cross beam, a lower cross beam, an upper longitudinal beam and a lower longitudinal beam;

[0049] The side plate assembly is formed by longitudinally laying side plate units with gradually decreasing thickness from the bottom to the top, and the side plate unit includes a front wall side plate unit and a side wall side plate unit;

[0050] The bottom plate assembly is formed by horizontally laying bottom plate units;

[0051] The top plate assembly is a single-layer plate structure, and the top plate assembly is connected with the upper longitudinal beam;

[0052] The lower longitudinal beam is connected with each bottom plate unit and each side wall side plate unit;

[0053] The lower cross beam is connected with the bottom plate unit, each front wall side plate unit and a vehicle longitudinal beam.

[0054] In the embodiment, it should be noted that the container is an important part of the truck and is a key structure for the van to transport goods. The national standard has upper limit provisions for the total weight and the load weight of the truck after loading. In order to facilitate the description, the subsequent embodiment takes a light truck as an example. The legal total mass of the light truck is 4.5 tons, and the legal load weight is 3.5 tons, that is, when the empty weight of the truck is 1 ton, 3.5 tons of goods can be fully loaded. However, the empty weight of the truck is much higher than 1 ton, so the truck usually cannot be fully loaded. If the weight of the truck itself can be reduced, the actual load capacity of the truck can be increased, the load cost can be reduced, and it has practical significance and economic value. In order to reduce the overall weight of the truck, the container of the truck begins to use low-density materials. Compared with the commonly used iron materials, the strength of the aluminum alloy material is lower, the lightweight container made of the aluminum alloy material has lower bearing capacity, and deformation is easy to occur during processing, assembly and application. Therefore, the main structure of the container is mostly a double-layer plate structure, or a support member made of high-strength material is added to make up for the strength of the low-density material. However, in this way, the weight reduction effect of the container will be affected.

[0055] For the convenience of description, refer to Figure 1 In the subsequent description, the x-axis direction refers to the direction parallel to the longer side of the lightweight container, the y-axis direction refers to the direction parallel to the shorter side of the lightweight container, and the z-axis direction refers to the direction parallel to the height direction of the lightweight container.

[0056] In the embodiment, the lightweight container is surrounded by a bottom plate assembly 10, a top plate assembly 20 and a side plate assembly 30. The bottom plate assembly 10, the top plate assembly 20 and the side plate assembly 30 are connected through a container frame.

[0057] The container frame, refer to Figure 2 may include two upper cross beams 41 and two upper longitudinal beams 42 arranged at the four edges of the top of the container, and two lower cross beams 43 and two lower longitudinal beams 44 arranged at the four edges of the bottom of the container. The upper cross beam 41 and the lower cross beam 43 are parallel to the y-axis, and the upper longitudinal beam 42 and the lower longitudinal beam 44 are parallel to the x-axis.

[0058] The side plate assembly 30 is longitudinally laid by side plate units with gradually decreasing thickness from bottom to top, the side plate units include at least one front wall side plate unit and at least one side wall side plate unit. Each of the side wall side plate units is inserted into the side plate mounting slot correspondingly arranged on the upper longitudinal beam 42 and the lower longitudinal beam 44, and the side wall side plate unit can be fixedly connected with the upper longitudinal beam 42 and the lower longitudinal beam 44 at intervals. Each of the front wall side plate units is inserted into the side plate mounting slot correspondingly arranged on the upper transverse beam 41 and the lower transverse beam 43. The thickness of the front wall side plate unit and the side wall side plate unit gradually decreases from bottom to top. Since the force bearing of the side plate unit decreases as it is closer to the top, the requirement for strength also gradually decreases. Therefore, the side plate unit decreases in thickness from bottom to top as the requirement for strength decreases, which can effectively reduce the total mass of the side plate unit while meeting the strength requirement. The thickness decreasing mode can be stepwise or smooth, which is not limited in the embodiment.

[0059] In an implementable mode, the side plate unit can include at least one rear wall side plate unit, each of the rear wall side plate units is inserted into the side plate mounting slot correspondingly arranged on the upper transverse beam 41 and the lower transverse beam 43, and the thickness of the rear wall side plate unit gradually decreases from bottom to top, which can be stepwise or smooth, which is not limited in the embodiment. The side plate unit can not include the rear wall side plate unit, in which case the lightweight cargo box includes a cargo box rear door, which can replace the rear wall side plate unit.

[0060] In an implementable mode, the side wall and / or the rear wall of the vehicle can be provided with a cargo box door. The cargo box door includes a door plate and a door frame, the door plate can be improved in rigidity by die pressing, the door frame is in the shape of “eye”, and the door plate and the door frame are connected and fixed by laser welding. Vertical columns 45 perpendicular to the bottom plate assembly 10 can be arranged on both sides of the cargo box door, the door frame and the vertical columns 45 are fixed by hinges, and each of the vertical columns 45 can be a hollow extruded section. The hollow structure of the vertical column 45 can greatly reduce its weight, and still provide strong support in the direction perpendicular to the bottom plate assembly 10, and can also play a role in dispersing stress in other directions, improving the load bearing capacity and strength of the cargo box.

[0061] The bottom plate assembly 10 is composed of at least one bottom plate unit 11, and in the case that the bottom plate assembly 10 is composed of multiple bottom plate units 11, each bottom plate unit 11 is laid horizontally, wherein the horizontal laying of the bottom plate unit 11 refers to placing the longer side of the bottom plate unit 11 parallel to the direction of the y-axis and laying along the y-axis direction, and the two ends of the bottom plate unit 11 are supported on the lower longitudinal beams 44. Since the distance between the lower cross beam 43 at the head of the cargo box and the lower cross beam 43 at the tail of the cargo box is large, if the bottom plate unit 11 is laid vertically, the distance of the middle part of the bottom plate unit 11 hanging in the air is large, and deformation is prone to occur when carrying a load, so it is necessary to add a bottom plate cross beam, which will increase the weight of the cargo box. Therefore, in the embodiment, the bottom plate unit 11 is laid horizontally, the distance between the two lower longitudinal beams 44 of the cargo box is small, so that the laying of the bottom plate cross beam can be reduced, thereby reducing the weight of the cargo box. The bottom plate unit 11 can be a single-layer plate structure, a double-layer plate structure, etc., and the actual load-bearing requirement of the cargo box can be determined, which is not limited in the embodiment.

[0062] The lower longitudinal beam 44, referring to Figure 3 and Figure 4 , is used to connect the side wall side plate unit and the bottom plate assembly 10, each side wall side plate unit is inserted into the corresponding side plate mounting groove of the lower longitudinal beam 44, the lower longitudinal beam 44 with the side wall side plate unit inserted thereon is overlapped on the bottom plate assembly 10 composed of the bottom plate units 11, and part of the bottom plate units 11 and the lower longitudinal beam 44 can be integrally connected or mechanically connected.

[0063] The upper longitudinal beam 42 is used to connect the side wall side plate unit and the top plate assembly 20, each side wall side plate unit is inserted into the corresponding side plate mounting groove of the upper longitudinal beam 42, and the top plate assembly 20 composed of the top plate units is overlapped on the upper longitudinal beam 42 with the side wall side plate unit inserted thereon. The top plate assembly 20 is relatively light and has a small load-bearing capacity, so the top plate assembly 20 and the upper longitudinal beam 42 can be connected by adhesion.

[0064] The lower cross beam 43, referring to Figure 5 , is used to connect the front wall side plate unit, the bottom plate assembly 10 and the vehicle longitudinal beam, each front wall side plate unit is inserted into the corresponding side plate mounting groove of the lower cross beam 43, the lower cross beam 43 with the front wall side plate unit inserted thereon is overlapped on the bottom plate unit 11, and the lowermost end of the lower cross beam 43 is overlapped on the vehicle longitudinal beam, and part of the bottom plate unit 11, the lower longitudinal beam 44 and the vehicle longitudinal beam can be integrally connected or mechanically connected, so as to transfer the load-bearing capacity of the lower cross beam 43 to the vehicle longitudinal beam.

[0065] Optionally, the connection mode between each structural unit in the lightweight cargo box includes mechanical connection through a connecting piece.

[0066] In the embodiment, the connection between the structural units in the lightweight container can be cold connection, including mechanical connection through connecting pieces, wherein the connecting pieces include angle plates 50, bolts 60, rivets, etc. Compared with hot connection such as welding, cold connection has less influence on the deformation of the aluminum alloy substrate 111, and thus only the strength required by the container is met, without the need for thickening treatment or adding structural members to avoid processing deformation, thereby reducing the weight of the container.

[0067] In an implementable manner, the connecting pieces include bolts 60 and angle plates 50.

[0068] In the embodiment, due to the lightweight requirement of the container, when designing the structural units of the container, the shape and size are designed to meet only the basic strength requirement, and thus the shape and size will be irregular. Mechanical connection through the bolts 60 and the angle plates 50 can better connect the structural units with irregular shapes. For example, the angle plates 50 can connect two structural units separated by a distance or two structural units not arranged in parallel, without the need for additional structural units, thereby effectively reducing the weight of the container.

[0069] Optionally, the container framework includes at least one column 45, each column 45 is a hollow extruded section, and each column 45 is connected between the side plate assembly 30, the bottom plate assembly 10, the top plate assembly 20, and the container framework.

[0070] In the embodiment, referring to Figure 2 , the container framework includes at least one column 45, each column 45 is a hollow extruded section, and the hollow extruded section has a small weight and can be easily connected and fixed between the side plate assembly 30, the bottom plate assembly 10, the top plate assembly 20, and the container framework, thereby providing strong support for the side plate assembly 30, the bottom plate assembly 10, the top plate assembly 20, and the container framework, and improving the load capacity and strength of the container.

[0071] Optionally, the bottom plate assembly 10 is formed by transversely laying a plurality of single-layer plate structural units and a double-layer plate arched bridge structural unit in the direction from the front to the rear of the vehicle.

[0072] In the embodiment, the bottom plate assembly 10 is spliced by multiple bottom plate units 11. Since the load bearing requirements of the bottom plates at different positions are different, the strength requirements are different, therefore multiple single-layer plate structure units and one double-layer plate arch bridge structure unit are laid in the direction from the front end to the tail end of the vehicle, the end close to the tail end of the vehicle is the edge of the bottom plate assembly 10, the stress is difficult to disperse to other structures, and the tail end of the vehicle is usually provided with a truck rear door, the truck rear door is most frequently subjected to the weight of goods and people during the process of carrying goods, and therefore the strength requirement is higher, therefore the double-layer plate arch bridge structure unit is laid at the end close to the tail end of the vehicle; and the bottom plate units 11 at other positions are spliced with adjacent bottom plate units 11 around, and the stress can be dispersed to other bottom plate units 11 around when stressed, and therefore the strength requirement is lower, therefore the single-layer plate structure unit can meet the strength requirement, and the weight of the single-layer plate structure unit is smaller than that of the double-layer plate arch bridge structure unit, and therefore the weight reduction can be further realized under the condition of meeting the strength requirement.

[0073] In an implementable mode, referring to 6, the double-layer plate arch bridge structure unit comprises a horizontal upper layer plate 115, an arch-shaped lower layer plate 116, support ribs 112 at both ends, and a reinforcing rib 117 arranged between the upper layer plate and the lower layer plate 116, and the double-layer plate arch bridge structure unit has strong load bearing capacity.

[0074] Optionally, referring to Figure 7 , the single-layer plate structure unit comprises:

[0075] an aluminum alloy base plate 111;

[0076] multiple support ribs 112 arranged at intervals, the support ribs 112 being connected with the aluminum alloy base plate 111;

[0077] at least one short rib 113 arranged between two adjacent support ribs 112 and connected with the aluminum alloy base plate 111;

[0078] at least one inclined rib 114 arranged between the adjacent support rib 112 and the short rib 113, one end of the inclined rib 114 being connected with the support rib 112 and the other end being connected with the aluminum alloy base plate 111.

[0079] In the embodiment, the main structure of the single-layer plate structure unit is an aluminum alloy substrate 111; a plurality of support ribs 112 are arranged at intervals on the aluminum alloy substrate 111, one end of the support rib 112 is connected with the aluminum alloy substrate 111, and the other end is supported on the lower longitudinal beam 44 and the vehicle longitudinal beam after being laid horizontally, so as to support the entire floor assembly 10 and the goods carried on the floor assembly 10 by supporting the longitudinal beam through the support rib 112. The plug-in structure is arranged on the two support ribs 112 at the outermost side of each floor unit 11, and the floor unit 11 can be connected with the adjacent floor unit 11 through the plug-in structure on the support rib 112. The support rib 112 can be arranged or not arranged between the two support ribs 112 at both ends; at least one short rib 113 is arranged between the two adjacent support ribs 112 and perpendicular to the aluminum alloy substrate 111, the length of the short rib 113 is less than that of the support rib 112, and the suspended short rib 113 can improve the rigidity of the floor unit 11 in the length direction and prevent the floor unit 11 from being deformed under pressure when carrying goods; the inclined rib 114 is arranged between the adjacent support rib 112 and the short rib 113, one end of the inclined rib 114 is connected with the support rib 112, and the other end is connected with the aluminum alloy substrate 111, so as to improve the rigidity of the floor unit 11 in the width direction and effectively prevent the deformation of the support rib 112 and the single-layer plate in the width direction of the floor unit 11.

[0080] In an implementable manner, the width of the aluminum alloy substrate 111 is 350mm-450mm.

[0081] In the embodiment, the width of the aluminum alloy substrate 111 is 350mm-450mm, and exemplarily, it can be 350mm, 375mm, 390mm, 420mm, 450mm, etc.

[0082] In an implementable manner, the interval distance between the two adjacent support ribs 112 is 180mm-220mm.

[0083] In the embodiment, the interval distance between two adjacent support ribs 112 is 180-220 mm, for example, 180 mm, 200 mm, 220 mm, etc. At present, the width of the bottom plate unit 11 is about 300 mm, and about 5 support ribs 112 or reinforcing ribs are arranged on each bottom plate unit 11 for support, and the interval distance between adjacent support ribs 112 or reinforcing ribs is about 70-80 mm. The support ribs 112 and the short ribs 113 can reinforce the bearing capacity of the bottom plate unit 11, so that the distance between the support ribs 112 can be increased, the width of the bottom plate unit 11 can be increased, the bearing area of the bottom plate unit 11 can be increased, and the bearing capacity of the bottom plate unit 11 can be improved. At the same time, the increase of the width of the bottom plate unit 11 can reduce the number of bottom plate units 11 required for laying the bottom plate assembly 10. In addition, the reduction of the number of support ribs 112 can also reduce the installation process, save labor cost and economic cost.

[0084] In an implementable manner, the interval distance between adjacent support ribs 112 and short ribs 113 is 80-120 mm.

[0085] In the embodiment, the interval distance between adjacent support ribs 112 and short ribs 113 is 80-120 mm, for example, 80 mm, 100 mm, 120 mm, etc.

After the insertion support rib 1122 is inserted with the receiving support rib 1121 on the adjacent bottom plate unit 11, the insertion support rib 1122 is overlapped on the receiving support rib 1121, at this time, the stress on the insertion support rib 1122 is partially transferred to the receiving support rib 1121, so the thickness of the insertion support rib 1122 can be smaller than the thickness of the receiving support rib 1121, the thickness of the receiving support rib 1121 is 1.8 mm-2.2 mm, for example, can be 1.8 mm, 2.0 mm, 2.2 mm, etc., the thickness of the insertion support rib 1122 is 0.4 mm-0.6 mm, for example, can be 0.4 mm, 0.5 mm, 0.6 mm, etc., the reduction of the thickness of the insertion support rib 1122 can not only reduce the consumption of materials, thereby saving costs, but also reduce the mass of the bottom plate unit 11.

[0091] In the embodiment, after the insertion support rib 1122 and the receiving support rib 1121 are inserted, the two are connected and fixed together through a connecting piece.

[0092] Optionally, referring to Figure 5 , the light-weight container comprises a beam support pipe 70, the beam support pipe 70 is a hollow extruded section, the beam support pipe 70 is arranged between the insertion support rib 1122 close to the front end of the vehicle and the lower cross beam 43, and connects the insertion support rib 1122 close to the front end of the vehicle and the lower cross beam 43.

[0093] In the embodiment, the insertion support rib 1122 closest to the front wall side plate unit has a portion bent towards the front wall side plate, and independently bears stress. In a torsion working condition of the vehicle, the floor plate unit 11 closest to the front wall side plate unit bears greater stress, and is prone to deformation and fracture. Therefore, a cross beam support pipe 70 is arranged in the area between the insertion support rib 1122 closest to the front wall side plate unit and the lower cross beam 43. The cross beam support pipe 70 is a hollow extruded profile, and can be connected with the insertion support rib 1122 of the front wall side plate unit and the lower cross beam 43 through a connecting piece. The cross beam support pipe 70 can effectively disperse the stress on the insertion support rib 1122 closest to the front wall side plate unit, and avoid deformation or fracture of the floor plate unit 11 closest to the front wall side plate unit.

[0094] In an implementable manner, each surface of the cross beam support pipe 70 can be respectively fitted with the insertion support rib 1122 and the lower cross beam 43.

The insertion portion 311 abuts against the abutting section 3121 of the receiving portion 312 of the adjacent side plate unit 31. The receiving portion 312 includes an abutting section abutting against the insertion portion 311 of the adjacent side plate unit 31.

[0096] In the embodiment, the two ends of the side plate unit 31 connected with the adjacent side plate unit 31 are respectively provided with an insertion portion 311 and a receiving portion 312. The insertion portion 311 is bent towards the inside of the cargo box, and is used to abut against the abutting section 3121 of the receiving portion 312 of the adjacent side plate unit 31. The receiving portion 312 is bent towards the inside of the cargo box twice, and forms an abutting section used to abut against the insertion portion 311 of the adjacent side plate unit 31. In an implementable manner, when the insertion portion 311 and the receiving portion 312 of the adjacent side plate unit 31 abut against each other, the bent section of the insertion portion 311 is fitted with the first bent section of the receiving portion 312, and the fitted position can be fixed and connected through a connecting piece.

[0097] Optionally, referring to Figure 8 , the cargo box framework further includes a support column 80 embedded in the area surrounded by the receiving portion 312, the insertion portion 311 and the front wall side plate unit.

[0098] In the embodiment, the frame of the container further comprises support columns 80 which can be hollow extruded sections. The hollow structure of the support columns 80 can greatly reduce the weight of the support columns 80. The support columns 80 are embedded in the area surrounded by the receiving portions 312, the insertion portions 311 and the front side plate units, and can interact with the receiving portions 312, the insertion portions 311 and the front side plate units, thereby dispersing stress and providing strong support for the front side plate units, improving the load-bearing capacity and strength of the container.

[0099] In an implementable manner, three surfaces of the support columns 80 can be attached to the front side plate units.

[0100] Optionally, referring to Figures 9-11 , the upper cross beam 41 comprises at least one support cross beam 411, the support cross beam 411 comprises a cross beam groove 4112, and two support edges 4111 extend from the opening of the cross beam groove 4112 in the direction away from the groove, the cross beam groove 4112 opens towards the direction of the roof assembly 20, and each support edge 4111 is attached to the roof assembly 20.

[0101] In the embodiment, the upper cross beam 41 further comprises at least one support cross beam 411, the length of the support cross beam 411 matches the width of the roof assembly 20, the support cross beam 411 comprises a cross beam groove 4112, and two support edges 4111 extend from the opening of the cross beam groove 4112 in the direction away from the groove, the cross beam groove 4112 opens towards the direction of the roof assembly 20, and each support edge 4111 is attached to the roof assembly 20, thereby supporting the roof assembly 20.

[0102] Optionally, the middle section of the support cross beam 411 is arched towards the top of the vehicle.

[0103] In the embodiment, the middle section of the support cross beam 411 is arched towards the top of the vehicle, and the arching direction of the support cross beam 411 is consistent with the opening direction of the cross beam groove 4112, thereby arching the roof assembly 20 upwards. Multiple support cross beams 411 can lift the roof assembly 20 to form an arched structure with high middle and low sides, so that rain, snow or other objects falling on the roof assembly 20 can slide down along the slope of the arch, avoiding accumulation on the roof and reducing the pressure on the roof assembly 20. In addition, water can be prevented from entering the container.

[0104] Optionally, referring to Figure 12 , the lightweight container comprises roof stiffeners 90 which connect the upper cross beam 41 and the upper longitudinal beam 42.

[0105] In the embodiment, the lightweight container comprises a top plate reinforcing member 90, one end of which is connected with the upper cross beam 41 and the other end of which is connected with the upper longitudinal beam 42.

[0106] In the embodiment, the lightweight container is made of aluminum alloy material and comprises a bottom plate assembly, a top plate assembly, a side plate assembly and a container framework, wherein the container framework comprises an upper cross beam, a lower cross beam, an upper longitudinal beam and a lower longitudinal beam; the side plate assembly is formed by longitudinally laying side plate units with gradually decreasing thickness from the bottom to the top, the side plate assembly comprises side wall side plate units and front wall side plate units, wherein the side wall side plate units are formed by longitudinally laying side wall side plate units; the bottom plate assembly is formed by transversely laying bottom plate units; the top plate assembly is a single-layer plate structure and is connected with the upper longitudinal beam; the lower longitudinal beam connects the bottom plate units and the side wall side plate units; and the lower cross beam connects the bottom plate units, the front wall side plate units and the vehicle longitudinal beam. The lightweight container provided by the application is made of aluminum alloy material, which can fully guarantee the lightweight requirement of the container in terms of material, and then the strength is supplemented in terms of structure. The side plate units with gradually decreasing thickness from the bottom to the top can gradually increase the strength of the side plate units from the top to the bottom, which meets the bearing and strength requirements of the side plate itself, and the structure of the bottom thick and the top thin not only increases the strength of the bottom of the side plate units, but also provides certain support for the top thin part to enhance the strength of the top and increase the stability of the side plate. The transverse laying of the bottom plate units can effectively reduce the number of laid bottom cross beams, thereby effectively reducing the overall weight of the truck. The mechanical connection between the structural units by the connecting members has less influence on the deformation of the aluminum alloy base plate than the thermal connection such as welding, so that only the strength required by the container bearing is met, without the need for thickening treatment or the addition of structural members to avoid processing deformation, thereby reducing the weight increase of the container. Through CAE (Computer Aided Engineering) simulation analysis and comprehensive road test, it can be determined that the lightweight container provided by the application can meet the legal load weight of the truck, and the weight of the container is about 400 kg, which is greatly reduced compared with the existing container, that is, the lightweight container provided by the application can further reduce its own weight on the basis of guaranteeing the bearing capacity of the container. Due to the reduction of its own weight, the actual load weight of the truck can be further improved on the basis of meeting the national standard requirements of the total mass of the truck after loading, the load capacity of the truck is improved, and the technical problem of poor weight reduction effect of the existing aluminum alloy container is overcome.

[0107] Further, the application also provides a vehicle comprising the lightweight container as described above.

[0108] The vehicle provided in the application solves the technical problem of poor weight reduction effect of the aluminum alloy container in the prior art. Compared with the prior art, the vehicle provided in the embodiment of the application has the same beneficial effects as the lightweight container provided in the above-mentioned embodiment, and thus is not described herein.

[0109] The above is only the preferred embodiment of the application, and does not limit the patent scope of the application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings of the application, or direct or indirect application in other related technical fields, is also included in the patent processing scope of the application.
