[0028] Application Overview

[0029] The existing aluminum alloy spliced ​​automobile tail panel bearing platform has a high initial investment cost because each specification of the aluminum alloy automobile tail panel needs to be manufactured with a separate mold, one version and one mold.

[0030] Based on the above technical problems, the present application proposes an aluminum alloy spliced ​​automobile tail panel bearing platform, wherein the aluminum alloy spliced ​​automobile tail panel bearing platform has a simple structure, does not involve complicated manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the aluminum alloy spliced ​​automobile tail panel bearing platform provided by the present application is easy to produce and low in cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0031] Schematic aluminum alloy splicing car tailgate bearing platform,

[0032] refer to Figure 1 to Figure 2 According to a preferred embodiment of the utility model, an aluminum alloy spliced ​​automobile tailgate bearing platform is provided. Figure 1 As shown, it includes a plurality of substrates 10, which are connected end to end in a flat manner, and each of the substrates 10 is made of aluminum alloy.

[0033] In order to realize the connection of multiple substrates 10, the aluminum alloy spliced ​​automobile tailgate supporting platform also includes a plurality of side panels 20 for connecting each substrate 10 into an integral whole. It should be noted that in the embodiment of the present application, the number of the side panels 20 is two, and the two side panels 20 are respectively located on both sides of each substrate 10, and each side panel 20 is connected to each substrate 10.

[0034] It should be noted that by splitting a whole piece of automobile tail panel with a larger width into multiple substrates 10 with smaller widths, the size of the production mold is smaller. Since the width of the substrate 10 is smaller at this time, when multiple substrates 10 with the same width are used for splicing, an overall size automobile tail panel with a multiple of the width can be obtained, thereby achieving the technical effect of assembling automobile tail panels of various specifications with one mold. Compared with the prior art in which the automobile tail panel is an integrated design and one mold and one version are required for mold opening, the embodiment of the present application has the advantages of modularity, low mold opening cost, and one mold for multiple uses.

[0035] It should also be noted that, since the base plate 10 is a load-bearing member in actual use, in order to reduce the risk of a single base plate 10 flipping over compared to the adjacent base plates 10, on the basis of the side plates 20 connecting each base plate 10, as shown in FIG. Figure 2 As shown, one end of each substrate 10 has an embedding portion 101 and an extending protrusion 102, and the other end of each substrate 10 has a groove 103 and a notch 104. When the two substrates 10 are connected end to end, the embedding portion 101 and the extending protrusion 102 on one substrate 10 extend into the groove 103 and the notch 104 on the other substrate 10 respectively.

[0036] It should be supplemented that, when the two substrates 10 are spliced ​​together, the embedding portion 101 of one substrate 10 is aligned with the slot 103 in the length direction of the substrate 10, and the extending protrusion 102 is aligned with the notch 104. Subsequently, one substrate 10 is extended from the side direction of the other substrate 10, and the embedding portion 101 is engaged with the slot 103, and the extending protrusion 102 is abutted against the notch 104. At this time, the two substrates 10 are spliced ​​together. Under the common limitation of the embedding portion 101 and the slot 103 and the extending protrusion 102 and the notch 104, the two substrates 10 cannot make relative up and down movement and flipping movements.

[0037] It should also be added that, by engaging the locking portion 101 with the locking groove 103 and the extending protrusion 102 with the notch 104, a pre-fixing effect is achieved for the multiple substrates 10, so that the assembler can connect the side panel 20 with each substrate 10 without having to worry about the position of the substrate 10 shifting during the process of connecting the side panel 20 with the substrate 10, which helps to improve the assembly efficiency; in addition, when splicing the substrates 10, the side panel 20 not only connects each substrate 10, but also plays a position limiting role in preventing any two adjacent substrates 10 from moving along the length direction of the substrate 10.

[0038] Furthermore, if the substrate 10 is solid, the cost is high and the weight will be further increased. In view of this, in the embodiment of the present application, Figure 2 As shown, each of the substrates 10 further includes an upper panel 105, a lower panel 106 and a plurality of ribs 107, wherein the ribs 107 are located between the upper panel 105 and the lower panel 106, and the top and bottom of the ribs 107 are respectively fixedly connected to the upper panel 105 and the lower panel 106, and the fixed connection method includes but is not limited to welding, and the two ends of the upper panel 105 respectively have the embedding portion 101 and the slot 103, and the two ends of the lower panel 106 respectively have the extending protrusion 102 and the notch 104.

[0039] It should be noted that, by providing the rib plate 107, a supporting force is provided to the upper panel 105 while connecting the upper panel 105 and the lower panel 106. The rib plate 107 is further implemented to be arranged in an inclined manner, and the inclination directions of two adjacent rib plates 107 are opposite.

[0040] In addition, since the upper panel 105 is a treading transportation surface, the thickness of the upper panel 105 is greater than the thickness of the lower panel 106 and the rib plate 107 .

[0041] In addition, in order to further enhance the connection strength of the adjacent substrates 10, as Figure 2 As shown, both ends of the upper panel 105 and the lower panel 106 have a removal portion 1051, and the two removal portions 1051 on the upper panel 105 or the lower panel 106 are symmetrically arranged. When the two substrates 10 are connected end to end, the removal portions 1051 on the two substrates 10 are spliced ​​to form an open groove (not marked in the figure), and any two adjacent substrates 10 are welded, and the corresponding open groove is filled with solder.

[0042] It should be noted that in the embodiment of the present application, the removal portion 1051 is further implemented as a chamfer. When the two substrates 10 are connected end to end, the opening groove is a V-shaped groove. Due to the opening of the opening groove, the solder can fully contact and connect with the substrate 10 during welding.

[0043] Further, the side plate 20 is bolted to each of the base plates 10. More specifically, as Figure 2 As shown, both ends of each of the base plates 10 have a plurality of connection holes 108 for connecting with the side plates 20, and the connection holes 108 are threaded holes. The side plates 20 have a plurality of corresponding through holes (not marked in the figure), and bolts are passed through the through holes and the connection holes 108 in sequence to achieve connection between the side plates 20 and the base plates 10.

[0044] Furthermore, in order to increase the friction of the upper panel 105, as Figure 2 As shown, the upper panel 105 has a plurality of first anti-slip bosses 1051 .

[0045] Furthermore, in order to obtain more combinations after splicing, the substrate 10 includes several first splicing plates and several second splicing plates, the width of the first splicing plates is 200mm~300mm, the width of the second splicing plates is 160mm~280mm, the thickness of the first splicing plates and the second splicing plates is 30mm~50mm, and when splicing, the width of the second splicing plates is 20mm~40mm smaller than the width of the first splicing plates.

[0046] It should be noted that, assuming that the width of the first splicing board is 230mm and the width of the second splicing board is 200mm, the splicing combinations of the substrate 10 within the range of 1.4 meters to 1.6 meters include: 1. Using 7 pieces of the second splicing boards to splice end to end to obtain a 1400mm automobile tail plate; 2. Using 6 pieces of the second splicing boards and 1 piece of the first splicing board to splice end to end to obtain a 1430mm automobile tail plate; 3. Using 5 pieces of the second splicing boards and 2 pieces of the first splicing boards to splice end to end to obtain a 1460mm automobile tail plate; 4. Using 4 pieces of the second splicing boards to splice end to end to obtain a 1460mm automobile tail plate; 1. The second splicing plate and three of the first splicing plates are spliced ​​end to end to obtain a 1490mm automobile tail plate; 2. The second splicing plates and five of the first splicing plates are spliced ​​end to end to obtain a 1520mm automobile tail plate; 3. The second splicing plates and three of the first splicing plates are spliced ​​end to end to obtain a 1520mm automobile tail plate; 4. The second splicing plates and five of the first splicing plates are spliced ​​end to end to obtain a 1550mm automobile tail plate; 5. The second splicing plates and six of the first splicing plates are spliced ​​end to end to obtain a 1580mm automobile tail plate; 6. The second splicing plates and eight of the second splicing plates are spliced ​​end to end to obtain a 1600mm automobile tail plate. Obviously, by designing the one-piece automobile tail plate to be split into multiple substrates 10 for splicing, it has a higher economic benefit.

[0047] Furthermore, in order to achieve the transition between the substrate 10 and the bottom surface, as Figure 2 As shown, the aluminum alloy spliced ​​automobile tailgate bearing platform further includes a transition plate 30, the end of the transition plate 30 is connected to the side plate 20, one side of the transition plate 30 is connected to the base plate 10, and the top surface of the transition plate 30 is a slope.

[0048] In addition, if Figure 2 As shown, the transition plate 30 has a plurality of second anti-skid bosses (not marked in the figure), and the distance between two adjacent second anti-skid bosses is smaller than the distance between two adjacent first anti-skid bosses 1051 .

[0049] In summary, the aluminum alloy spliced ​​automobile tail panel bearing platform based on the embodiment of the present application is explained, which provides the aluminum alloy spliced ​​automobile tail panel bearing platform with advantages such as modularity, low mold opening cost, and one mold for multiple uses.

[0050] It is worth mentioning that in the embodiment of the present application, the aluminum alloy spliced ​​automobile tailboard bearing platform has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the aluminum alloy spliced ​​automobile tailboard bearing platform provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
