Description

Technical Field

[0001] The utility model relates to the field of vehicles, and particularly to a cargo box floor, a cargo box and a vehicle. Background Art

[0002] The current van-type transport vehicle has a lightweight independent cargo box. The whole cargo box is assembled by honeycomb panels and aluminum alloy skeletons, and the cargo box floor is assembled by honeycomb panels and aluminum alloy frames. Before the cargo box is assembled with the vehicle frame, the structure of the cargo box floor is usually strengthened.

[0003] There are two strengthening methods in the related art. The first method is to install steel support beams on the lower surface of the cargo box floor. The support beams are divided into two layers. The first layer is directly connected to the cargo box floor and is a horizontally arranged support beam. The second layer is connected to the first layer and is a vertically arranged support beam. The second layer of support beam is connected to the vehicle frame to realize the connection between the cargo box and the vehicle frame. The second method is to directly drill holes in the cargo box floor, pass bolts through the holes, and strengthen the surrounding of the holes on the other side of the cargo box floor with steel plates to connect the cargo box to the vehicle frame. However, for the first method, the skeleton structure under the cargo box floor is complex and occupies a large space, and it is only applicable to large cargo boxes. For the second method, the skeleton structure strength under the cargo box floor is weak, which is not conducive to bearing the dynamic load of heavy objects. Summary of the Utility Model

[0054] The following will be combined with Figures 1 to 16 to introduce the cargo floor, cargo box, and vehicle provided by the embodiments of this utility model.

[0055] Such as Figure 1 , Figure 2 ,Figure 13 and Figure 14 As shown in Figure 14 , an embodiment of the first aspect of the present utility model provides a cargo box floor, which includes a floor main body 10, a support beam assembly 30 located on one side of the floor main body 10, and a frame structure 20 surrounding the outer periphery of the floor main body 10 and the outer periphery of the support beam assembly 30. Among them, an installation groove 240 is provided inside the frame structure 20, the edge of the floor main body 10 is inserted into the installation groove 240, and the end of the support beam assembly 30 is inserted into the installation groove 240.

[0056] For the cargo box floor provided by the embodiment of this aspect, an installation groove 240 is provided on the frame structure 20. The edge of the floor main body 10 is inserted into the installation groove 240, and the end of the support beam assembly 30 is also inserted into the installation groove 240. The overall structure of the cargo box floor has high strength and good integrity, which is beneficial to bearing the dynamic load of heavier objects. Moreover, the support beam assembly 30 and the floor main body 10 are jointly assembled into the frame structure 20, and the cargo box floor has a compact structure and small occupied space, which is not only applicable to large cargo boxes but also to small-sized cargo boxes, with good versatility. Moreover, the overall appearance of the cargo box floor is relatively square, without protrusions on the outside, which is convenient for flat placement and transportation.

[0057] In addition, the edge of the floor main body 10 is inserted into the installation groove 240 and is wrapped by the frame structure 20, which can improve the structural strength of the edge of the floor main body 10. The end of the support beam assembly 30 is also inserted into the installation groove 240 and hidden in the installation groove 240, with good appearance effect. In addition, the support beam assembly 30 and the floor main body 10 can be horizontally pushed into the installation groove 240 for assembly, which is convenient for operation.

[0058] For the specific structure of the frame structure 20, further, in some embodiments, as Figure 7 , Figure 8 and Figure 9 shown, the frame structure 20 includes a plurality of frames circumferentially distributed around the floor main body 10. Each frame includes an upper edge 210, a lower edge 230, and a side edge 220. The side edge 220 is located between the upper edge 210 and the lower edge 230, and the upper edge 210, the side edge 220, and the lower edge 230 enclose an installation groove 240 with an opening facing inward.

[0059] Here, referring to Figure 9 and Figure 14 , the frame structure 20 as a whole encloses an installation groove 240, and the installation groove 240 is distributed around the floor main body 10 along with the frame structure 20 for one week. During assembly, after the edge of the floor main body 10 is inserted into the installation groove 240, the thickness of the floor main body 10 is less than the width of the installation groove 240, and a certain space is reserved in the installation groove 240 for the support beam assembly 30 to be inserted. A relatively wide installation groove 240 realizes the common limit of the floor main body 10 and the support beam assembly 30, with a simple structure and convenient processing.

[0060] During specific assembly, the support beam assembly 30 is arranged below the bottom plate main body 10, so that the bottom wall surface inside the cargo compartment is relatively smooth and convenient to use.

[0061] To improve the structural strength of the frame structure 20, further, as Figure 9 shown, the side edge wrapping 220 is constructed by a hollow frame. Here, the side edge wrapping 220 is not a single-layer plate structure, but a frame with a cavity inside, which has high structural strength and can effectively reduce the probability of bending deformation of the cargo compartment bottom plate and improve the load-bearing capacity of the cargo compartment bottom plate.

[0062] As an example, as Figure 9 shown, the cross-section of the side edge wrapping 220 is in a square shape. The upper edge wrapping 210 extends inward from one side top of the side edge wrapping 220, and the lower edge wrapping 230 extends inward from one side bottom of the side edge wrapping 220. The upper edge wrapping 210, the side wall of the side edge wrapping 220, and the lower edge wrapping 230 enclose an installation groove 240.

[0063] Of course, in some other embodiments, as Figure 15 and Figure 16 shown, the frame structure 20 may further include an upper edge wrapping 210, a lower edge wrapping 230, a side edge wrapping 220, and a spacer 250. The side edge wrapping 220 is located between one edge of the upper edge wrapping 210 and one edge of the lower edge wrapping 230. The spacer 250 is connected to one side of the side edge wrapping 220 and is horizontally arranged between the upper edge wrapping 210 and the lower edge wrapping 230 to divide the installation groove 240 into a first sub-installation groove 241 and a second sub-installation groove 242. The first sub-installation groove 241 is enclosed by the upper edge wrapping 210, the side edge wrapping 220, and the spacer 250 and is used to accommodate the edge of the bottom plate main body 10. The second sub-installation groove 242 is enclosed by the spacer 250, the side edge wrapping 220, and the lower edge wrapping 230 and is used to accommodate the end of the support beam assembly 30.

[0064] Here, the spacer 250 is used to separate the end of the support beam assembly 30 and the edge of the bottom plate main body 10. During processing, it is only necessary to make the groove width of the corresponding sub-installation groove meet the corresponding requirements, which can avoid large vertical movement of the bottom plate main body 10 and the support beam assembly 30 in the frame structure 20 due to processing errors, facilitate the frame structure 20 to firmly wrap the edges of the bottom plate main body 10 and the support beam assembly 30, and improve the connection stability of the three. In addition, to ensure that the support beam assembly 30 stably supports the bottom plate main body 10, the part of the support beam assembly 30 that does not extend into the second sub-installation groove 242 can be made to fit the lower surface of the bottom plate main body 10 to avoid completely separating the support beam assembly 30 and the bottom plate main body 10 due to the existence of the spacer 250.

[0065] Of course, the frame structure 20 may not include the upper edge wrapping 210. In this case, the first sub-installation groove 241 still has a notch with an upward opening, which facilitates the bottom plate main body 10 to be placed into the space surrounded by the frame structure 20 from top to bottom, and can reduce the probability of wear when the bottom plate main body 10 slides along the frame structure 20 during installation. The frame structure 20 may also not include the lower edge wrapping 230. In this case, the second sub-installation groove 242 still has a notch with a downward opening. The bottom plate main body 10 can be placed with its back facing up, and then the support beam assembly 30 can be placed into the space surrounded by the frame structure 20 from top to bottom. The installation is convenient, and the probability of wear when the support beam assembly 30 slides along the frame structure 20 during installation can be reduced. The side edge wrapping 220 may not be constructed of the hollow frame as shown in Figure 15 and Figure 16 either, and can also be a single-layer plate structure.

[0066] The number of frames can be determined according to the shape of the bottom plate main body 10, and the shape of the bottom plate main body 10 can be determined according to the shape of the vehicle frame.

[0067] As an example, the bottom plate main body 10 is rectangular, and the frame structure 20 includes four frames, which are distributed at the four edges of the bottom plate main body 10.

[0068] As an example, as shown in Figure 2 , the bottom plate main body 10 is generally rectangular, and has chamfers at two corners at one end to match the shape of the vehicle frame. The frame structure 20 includes six frames, namely four long frames and two short frames. The four long frames are correspondingly distributed at the four edges of the bottom plate main body 10, and the two short frames are correspondingly distributed at the two chamfers of the bottom plate main body 10. The six frames are connected end to end to surround the bottom plate main body 10 for one week. Refer to Figure 2 , the frame structure 20 includes a front frame 263, a left frame 261, a right frame 262, a rear frame 264, a left rear corner frame 265, and a right rear corner frame 266.

[0069] Regarding the specific structure of the support beam assembly 30, further, in some embodiments, as shown in Figure 1 , Figure 10 and Figure 11 , the support beam assembly 30 includes a plurality of support beams in the same horizontal plane. Here, the plurality of support beams are distributed in the same horizontal plane, rather than stacked in multiple layers, which reduces the occupied space.

[0070] As an example, the plurality of support beams include a plurality of support cross beams, and the plurality of support cross beams are spaced apart along the length direction of the bottom plate main body 10, and both ends of each support cross beam are inserted into the installation groove 240.

[0071] As shown in Figure 13As shown, the multiple support beams include four support cross-beams, namely the first support cross-beam 310, the second support cross-beam 320, the third support cross-beam 330, and the fourth support cross-beam 340. Among them, the first support cross-beam 310 and the fourth support cross-beam 340 are distributed at both ends of the bottom plate main body 10 in the length direction, and the second support cross-beam 320 and the third support cross-beam 330 are distributed between the first support cross-beam 310 and the fourth support cross-beam 340 according to the load-bearing requirements.

[0072] As an example, the multiple support beams include multiple support longitudinal beams (not shown in the figure). The multiple support longitudinal beams are spaced apart along the width direction of the bottom plate main body 10, and both ends of each support longitudinal beam are inserted into the installation groove 240.

[0073] As an example, the multiple support beams include at least one support cross-beam and at least one support longitudinal beam (not shown in the figure) that are cross-distributed. Both ends of the at least one support cross-beam and the at least one support longitudinal beam are inserted into the installation groove 240. Here, notches can be provided on both the support cross-beam and the support longitudinal beam, and the notches are butted to plug them together. Or the support cross-beam can be welded to the side wall of the support longitudinal beam, or the support longitudinal beam can be welded to the side wall of the support cross-beam. The multiple support beams can be distributed in a grid pattern or a checkerboard pattern, etc.

[0074] Of course, in other embodiments, the multiple support beams can also include multiple layers of support beams that are distributed vertically, and both ends of the multiple layers of support beams are inserted into the installation groove 240. The cargo box bottom plate has good integrity and high structural strength, which is beneficial to bearing the dynamic load of heavier objects. In this case, both ends of the multiple layers of support beams and the bottom plate main body 10 can be inserted into a larger installation groove 240 together, or the bottom plate main body 10 can be inserted into a sub-installation groove alone, and both ends of the multiple layers of support beams are inserted into another sub-installation groove together. Or the bottom plate main body 10 and each layer of support beam can be inserted into a sub-installation groove alone.

[0075] Furthermore, as Figures 12 to 14 shown, the support beam in the support beam assembly 30 is a hollow beam. The support beam assembly 30 with this structure uses less material, has a light weight, and is not easily bent and deformed.

[0076] Regarding the connection method of the bottom plate main body 10, the support beam assembly 30, and the frame structure 20, further, in some embodiments, the bottom plate main body 10, the frame structure 20, and the support beam assembly 30 are connected to each other in pairs, and the overall structure is firmly connected with good load-bearing capacity.

[0077] As Figures 3 to 9 、 Figure 11 and Figure 12As shown, the cargo box floor includes a plurality of first connectors 40, which are circumferentially distributed along the frame structure 20. The plurality of first connectors 40 connect the floor main body 10 and the frame structure 20 together. The cargo box floor further includes a plurality of second connectors 50, which are circumferentially distributed along the frame structure 20. The plurality of second connectors 50 connect the end of the support beam assembly 30 and the frame structure 20 together. The plurality of first connectors 40 and the plurality of second connectors 50 respectively extend into the installation groove 240 from both sides of the floor main body 10. The connection is convenient and does not interfere with each other.

[0078] As an example, the plurality of first connectors 40 are blind rivets. The blind rivets pass through one side of the frame structure 20 and extend into the installation groove 240, and then extend into the edge of the floor main body 10. The blind rivets do not penetrate the floor main body 10 or the other side of the frame structure 20, which is beneficial to ensuring the structural strength of the floor main body 10 and the frame structure 20.

[0079] As an example, the plurality of second connectors 50 are bolts. The bolts pass through the other side of the frame structure 20 and are inserted into the support beam assembly 30. Connecting the frame structure 20 and the support beam assembly 30 by bolts provides a firm connection.

[0080] As an example, the plurality of second connectors 50 are blind rivets. The blind rivets pass through the other side of the frame structure 20 and are inserted into the support beam assembly 30.

[0081] As Figures 10 to 14 shown, the cargo box floor further includes a plurality of third connectors 60, which connect the support beam assembly 30 and the floor main body 10 together. Ensure a firm connection between the support beam assembly 30 and the floor main body 10.

[0082] As an example, the plurality of third connectors 60 are blind rivets. The blind rivets pass through the support beam and extend into the floor main body 10. The blind rivets do not penetrate the floor main body 10, which is beneficial to ensuring the structural strength of the floor main body 10 and can firmly connect the floor main body 10 and the support beam assembly 30 together.

[0083] In addition, in the case where the support beam is a hollow beam, referring to Figure 12 and Figure 14 , after the blind rivets are riveted, they can be hidden inside the support beam without protruding, resulting in a good appearance effect and not affecting the stable placement of the cargo box floor on the vehicle frame.

[0084] Furthermore, in some embodiments, the floor main body 10 is a honeycomb floor, the frame structure 20 is an aluminum alloy frame, and the support beam assembly 30 is a steel beam assembly. While the cargo box floor is not too heavy, it has high structural strength, is not easily deformed, and can withstand the dynamic load of heavy objects.

[0085] Of course, the bottom plate main body 10 may not be a honeycomb bottom plate. The frame structure 20 and the support beam assembly 30 may both be made of steel or both be made of aluminum alloy.

[0086] Furthermore, in some embodiments, as Figures 10 to 13 shown, the cargo compartment bottom plate further includes a first soft support structure connected to the support beam assembly 30. The first soft support structure includes a mounting portion 70 and a first elastic portion (not shown in the figure) provided on the mounting portion 70. The first elastic portion is used to abut against the vehicle frame.

[0094] The vehicle provided by the embodiment of this aspect has the beneficial effects of the second aspect embodiment due to having the cargo compartment of the second aspect embodiment, and will not be elaborated here.

[0095] The cargo box floor of an embodiment of the present utility model will be introduced in detail below.

[0096] As Figure 1 shown, the cargo box floor is assembled by a honeycomb floor, an aluminum alloy frame structure, a steel support beam assembly 30, etc. The use of a honeycomb floor and an aluminum alloy frame structure can lighten the weight of the cargo box floor. The use of a steel support beam can improve the load-bearing capacity of the cargo box floor.

[0097] The honeycomb floor is directly cut from a finished sheet. The frame structure 20 is welded into a whole by six sections of frames with different sizes. The support beam assembly 30 includes four cross beams, which are respectively welded by steel bending parts.

[0098] When welding the frame structure 20, first weld the three sections of the front frame 263, the left frame 261 and the right frame 262, then insert the honeycomb floor into the formed installation groove 240, and finally weld the rear frame 264, the left rear corner frame 265 and the right rear corner frame 266 。

[0099] As Figures 2 to 9 shown, the welded frame structure 20 and the honeycomb floor are assembled together with rivets (the first connecting piece 40). Referring to FIGS. 7 to Figure 9 , a first installation hole 211 is provided on the upper edge 210 of the frame structure 20, a second installation hole 110 is provided on the side of the floor main body 10 facing the upper edge 210, the rivet passes through the first installation hole 211 and is inserted into the second installation hole 110, and a certain space will be reserved in the installation groove 240 for the end of the cross beam to be inserted. Comparing Figure 4 and Figure 6 , after riveting, the rivet will not protrude outward in a large size, which can ensure the flatness of the surface of the cargo box floor, facilitate the flat docking of the cargo box floor and the cargo box side plate, and can also prevent the protruding structure from interfering with the items placed in or taken out of the cargo box.

[0100] After assembling the frame structure 20 and the honeycomb floor, the two ends of the four cross beams are respectively clamped into the previously reserved installation groove 240, aligned with the corresponding installation holes, and the cross beam is connected to the frame structure 20 with bolts (the second connecting piece 50), and the cross beam is connected to the honeycomb floor with rivets (the third connecting piece 60).

[0101] As Figures 10 to 14 shown, a third installation hole 231 is provided on the lower edge 230 of the frame structure 20, a fourth installation hole 350 is provided at the end of the cross beam. When installing the cross beam, align the fourth installation hole 350 of the cross beam with the third installation hole 231, and then insert the bolt through the third installation hole 231 and into the fourth installation hole 350 to realize the connection between the frame structure 20 and the cross beam.

[0102] The cross beam is a hollow beam. A fifth mounting hole 360 is provided on the surface of the cross beam facing away from the honeycomb bottom plate. A sixth mounting hole 120 is provided on the corresponding part of the bottom plate body 10 to the fifth mounting hole 360. The sixth mounting hole 120 is a counterbore. The rivet passes through the fifth mounting hole 360 and is inserted into the sixth mounting hole 120. After riveting, the rivet will not protrude outside the cross beam, and the appearance effect is good. Moreover, it can ensure that the surface of the cross beam facing away from the honeycomb bottom plate is flat, which is conducive to being stably placed on the vehicle frame.

[0103] The cargo box bottom plate proposed in this embodiment has a compact structure and simple assembly. The support beam assembly 30 is integrated into the frame structure 20. There are connections between the honeycomb bottom plate, the aluminum alloy frame structure and the support beam assembly 30, with strong integrity and good bearing capacity. Moreover, it occupies a small space, is convenient for transportation, has no protrusions outside, and can be laid flat. In addition, the applicable cargo box size is not limited, and a set of structures has strong compatibility.

[0104] Although the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that in the view of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention defined by the claims.
