Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] like Figure 1 As shown, the present application provides a specific embodiment of a modular quick-disassembly and assembly apron, wherein the modular quick-disassembly and assembly apron comprises a plurality of square modular composite panels 1 assembled together, wherein the modular composite panels 1 are provided with a locking structure 2 for fixing the two modular composite panels 1 on at least one side of the modular composite panels 1 connected thereto.

[0031] In the prior art, aluminum alloy profiles or polymer materials (fiber reinforced resin) are generally used as road panels, and threaded or latched fittings are used to achieve assembly and connection. Firstly, aluminum alloy profiles or polymer materials (fiber reinforced resin) are used as road panels, which are limited by the characteristics of the materials themselves and will result in insufficient load-bearing capacity. At the same time, they are not conducive to multiple disassembly and assembly. Secondly, threaded or latched fittings are used to achieve assembly and connection, which makes disassembly more complicated and is prone to increased difficulty in disassembly due to deformation under stress.

[0032] like Figure 2 As shown, in order to solve the problem of rapid assembly, as a first implementation scheme of the locking structure 2, the locking structure 2 includes one of the adjacent modular composite panels 1 provided with a snap-fit ​​seat 2-1, and the other provided with an embedded portion 2-2 used in conjunction with the snap-fit ​​seat 2-1. Specifically, the snap-fit ​​seat 2-1 includes a snap-fit ​​groove 2-1-1 for locking two adjacent modular composite panels 1 when the embedded portion 2-2 is embedded. During the process of plugging adjacent modular composite panels 1, the embedded portion 2-2 is embedded in the snap-fit ​​groove 2-1-1, and when the adjacent modular composite panels 1 are separated, the embedded portion 2-2 is allowed to escape from the snap-fit ​​groove 2-1-1.

[0033] To further tighten, Figure 3 As shown, the snap-fit ​​seat 2-1 is provided with a locking portion 2-1-2 for locking the embedding portion 2-2 after embedding. The snap-fit ​​seat 2-1 includes a groove seat 2-1-3 and a pressing portion 2-1-4 for fixing the locking portion 2-1-2 on the snap-fit ​​seat 2-1; the snap-fit ​​groove 2-1-1 is formed on the groove seat 2-1-3. In actual use, the pressing portion 2-1-4 fixes the locking portion 2-1-2 on the snap-fit ​​groove 2-1-1 by means of bolts.

[0034] This application provides a specific implementation of the locking portion 2-1-2, such as Fig.11 As shown, the cross section of the locking portion 2-1-2 is an inverted Ω shape, which can satisfy the requirement that the embedded portion 2-2 is limited in the snap-fit ​​groove 2-1-1 below the locking portion 2-1-2 after being embedded.

[0035] The present application provides another specific implementation of the locking portion 2-1-2, wherein a protruding locking portion 2-1-2 is provided on the groove seat 2-1-3. The groove seat 2-1-3 and the locking portion 2-1-2 are integrally formed.

[0036] like Figure 4 As shown, as a second embodiment of the locking structure 2, the locking structure 2 includes one of the adjacent modular composite panels 1 provided with a flip buckle structure 2-3, and the other provided with a buckle seat 2-4 used in conjunction with the flip buckle structure 2-3. Specifically, the buckle seat 2-4 includes a buckle groove 2-4-1 for locking two adjacent modular composite panels 1 when the flip buckle structure 2-3 is buckled. During the process of plugging adjacent modular composite panels 1, the flip buckle structure 2-3 is embedded in the buckle seat 2-4, and when the adjacent modular composite panels 1 are separated, the flip buckle structure 2-3 is allowed to escape from the buckle seat 2-4.

[0037] The flip buckle ring structure 2-3 includes a buckle ring 2-3-1 used in conjunction with the buckle ring groove 2-4-1 to lock two adjacent modular composite panels 1 after the adjacent modular composite panels 1 are plugged in. The flip buckle ring structure 2-3 also includes a flip seat 2-3-2, and the flip seat 2-3-2 includes a storage groove 2-3-2-1 for storing the buckle ring 2-3-1 when the flip buckle ring structure 2-3 is opened. When in use, the buckle ring 2-3-1 is rotated to determine whether the buckle ring 2-3-1 is buckled in the buckle ring groove 2-4-1, thereby locking the flip buckle ring structure 2-3 or taking the buckle ring 2-3-1 out of the buckle ring groove 2-4-1 and rotating it to the storage groove 2-3-2-1 for storage.

[0038] like Figure 4 As shown, the buckle ring seat 2-4 is provided with a buckle ring locking portion 2-4-2 for locking the buckle ring 2-3-1 after it is inserted into the buckle ring groove 2-4-1. In actual use, the buckle ring locking portion 2-4-2 is fixed to the buckle ring groove 2-4-1 by bolts. The structure of the buckle ring locking portion 2-4-2 can be the same as that of the locking portion 2-1-2.

[0039] In order to achieve accurate alignment connection during the plug-in process of adjacent modular composite panels 1, Figure 5As shown, as a specific embodiment, it also includes: a first alignment structure 2-5 arranged on adjacent modular composite panels 1, wherein the first alignment structure 2-5 includes a groove member 2-5-1 arranged on the side of the modular composite panel 1 and a protrusion member 2-5-2 arranged on the side of the adjacent modular composite panel 1 and used in conjunction with the groove member 2-5-1. In this embodiment, the cross section of the protrusion member 2-5-2 is wedge-shaped.

[0040] As another specific implementation, a second alignment structure 2-8 is provided on the contact surface between the buckle seat 2-4 and the flip seat 2-3-2, and the second alignment structure 2-8 includes a docking piece provided on the buckle seat 2-4 and a docking counterpart provided on the flip seat 2-3-2 for use with the docking piece. Figure 4 As shown, in this embodiment, the docking member adopts a plurality of grooves arranged in parallel, and the docking counterpart adopts protrusions arranged corresponding to the grooves.

[0041] like Figure 6 As shown in the figure, as a third embodiment of the locking structure 2, the locking structure 2 includes one of the adjacent modular composite panels 1 is provided with a splicing block 2-6, and the other is provided with a splicing groove 2-7 used in conjunction with the splicing block 2-6. In order to improve the connection stability, the shape of the splicing block 2-6 is selected to be an Ω-shaped protrusion or an inverted trapezoidal protrusion, so that the splicing block 2-6 will not easily fall out of the splicing groove 2-7.

[0042] like Figure 1 , 9 As shown in Figure 10, the modular quick disassembly and assembly apron of the present application further includes a step buffer pad 3 provided on the outer edge of the outermost modular composite panel 1 when multiple modular composite panels 1 are assembled to provide slope buffer for the apron. Here, the outer edge refers to Figure 1 , 9 , 10, the outer boundaries of the plurality of modular composite panels 1 in the assembled state.

[0043] Specifically, the present application provides a specific implementation of a step buffer plate 3, wherein the step buffer plate 3 includes a straight-edge step buffer plate 3-1 and a corner step buffer plate 3-2 for forming an enclosed area; the step buffer plate 3 is fixed to an adjacent modular composite panel 1 through a locking structure 2.

[0044] Based on the above solution, the location and number of the locking structures 2 on the step buffer pad 3 can be adaptively selected according to the number of modular composite panels 1 to be spliced, provided that stability is met. In this embodiment, two locking structures 2 are provided on each right-angle edge.

[0045] When in use, the number of modular composite panels 1 to be spliced ​​can be 2, 4, 9 or more according to the size of the apron required by the aircraft. Specific splicing schemes include the following (choice of the locking structure 2):

[0046] 1. If Figure 7-8 As shown, a buckle seat 2-1, a buckle ring seat 2-4 and a splicing groove 2-7 are respectively arranged on three adjacent sides of a modular composite panel 1, and an embedded portion 2-2, a flip buckle ring structure 2-3 and a splicing block 2-6 are respectively arranged on three adjacent sides of another modular composite panel 1 adjacent thereto; when multiple modular composite panels 1 are assembled, they can be assembled according to the three schemes of the buckle structure 2;

[0047] 2. If Fig. 9 As shown, a flip buckle structure 2-3 is provided on four adjacent sides of a modular composite panel 1, and a buckle seat 2-4 used in conjunction with the flip buckle structure 2-3 is provided on another adjacent modular composite panel 1;

[0048] 3. As shown in 10, splicing blocks 2-6 are arranged on four adjacent sides of the modular composite panel 1, and splicing grooves 2-7 used in conjunction with the splicing blocks 2-6 are arranged on another adjacent modular composite panel 1;

[0049] 4. A snap-fit ​​seat 2-1 is provided on each of the four adjacent sides of the modular composite panel 1, and an embedding portion 2-2 used in conjunction with the snap-fit ​​seat 2-1 is provided on another adjacent modular composite panel 1;

[0050] The above solution can also be configured according to the use requirements by providing a part of a certain solution of the locking structure 2 on the modular composite panel 1 and providing another matching part on the adjacent modular composite panel 1. Based on the above solution, the step buffer plate 3 is adaptively matched according to the selection of the locking structure 2 of the modular composite panel 1.

[0051] The assembly process of the entire apron is to lay the modular composite board 1 and the step buffer pad 3 in place, and then twist the lock structure 2 at the corner joint to the corresponding position. When disassembling, remove the openable part of the lock structure 2, and then carry and pack the modular composite board 1 and the step buffer pad 3; the entire disassembly and assembly process is fast, efficient, and convenient to use.

[0052] The modular composite plate 1 includes a fully brazed metal plate and a metal reinforcement plate at least arranged on one side of the fully brazed metal plate.

[0053] In order to meet the requirements of light weight, large load-bearing capacity and impact resistance, the modular composite panel 1 uses a fully brazed metal plate as a base plate, which has the advantages of light weight, large load-bearing capacity and impact resistance. However, after the brazed metal plate is brazed, the strength of the material will decrease.

[0054] In order to further improve the strength, rigidity and load-bearing capacity of the fully brazed metal plate, metal reinforcement plates are added on both sides of the fully brazed metal plate, and the metal reinforcement plates maintain the high strength performance of the metal plate in the rolled state. To prevent slipping, the metal reinforcement plates can be made of anti-slip metal plates.

[0055] The modular composite plate 1 inherits the superior performance of the fully brazed metal plate and the rolled metal plate, and while meeting the lightweight requirements, achieves a significant improvement in surface strength, solving the problem of low strength of the brazed metal plate after welding.

[0056] Among them, the metal brazing plate 1-1 uses patent number 2021220133694, and the patent name is: a decking plate in a stackable combination pallet with stable transportation, the decking plate has a three-layer structure, the middle layer is a honeycomb core, and the upper and lower plates are fixedly connected on both sides of the honeycomb core. The upper and lower plates are both aluminum plates, and the honeycomb core is a metal honeycomb core. The lower aluminum plate, the metal honeycomb core and the upper aluminum plate are laid in a bottom-up order to form a three-layer structure, and then placed in a heat treatment furnace for brazing and fixing.

[0057] The helipad of the utility model adopts modular composite panels, locking structures and step buffer pads during assembly. The entire helipad can be quickly and conveniently assembled and disassembled, and is not prone to the problem of unchanged disassembly due to deformation during use. At the same time, the various components of the helipad are light and high-strength, meeting the requirements of manual field transportation. In addition, the helipad has a strong carrying capacity, which not only meets the parking requirements of low-altitude aircraft such as helicopters, but also meets the requirements of engineering vehicles getting on and off the platform, effectively improving the efficiency of field operations.

[0058] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
