Description

Technical Field

[0001] This application relates to the field of assembly technology, and in particular to a multi-layer stacked structure, an antenna, and an assembly method. Background Technology

[0002] Due to the limited space on the back of existing antennas, most of the components (such as phase shifters) need to be stacked. At the same time, considering the requirements for assembly efficiency and rework efficiency, the stacked modules are also required to be quick to install and remove.

[0003] For multi-layered structures of flat components, there are generally the following assembly methods:

[0004] 1)Reference Figure 1 As shown, multi-layer flat components are supported by hollow isolation sleeves 1', and the top and bottom layers are secured with a screw 2' whose length is greater than the cumulative thickness. If the screw length is insufficient, the components are divided into several modules, assembled separately, and then stacked together.

[0005] 2)Reference Figure 2 As shown, an elastic snap-fit ​​structure formed by an isolation column 3' similar to a "mushroom head" is used to assemble two layers of flat components. During the installation process, the elastic snap-fit ​​spring of the "mushroom head" is squeezed and deformed. After the assembly is completed, the spring is reset to achieve the limit. Each two layers form a group, and each two groups are connected by different mounting holes.

[0006] 3) By clamping flat-type components with two mounting pieces, multiple flat-type components can be stacked in multiple layers.

[0007] However, the above assembly methods have the following drawbacks:

[0008] 1) Support sleeve fixing scheme: Due to the limited length of the fastening screws, the number of stacked layers is limited. At the same time, considering the screw fastening, the assembly efficiency and disassembly efficiency are sacrificed. In addition, during the disassembly process, each layer is in a disassembled state and cannot be controlled.

[0009] 2) Isolation Post Fixing Solution: Due to structural limitations, only support between two layers can be guaranteed, but it is impossible to secure the components between the two layers. This leads to misalignment and wobbling after multi-layer assembly, resulting in poor overall stability. During disassembly, considerable force is required to squeeze the elastic structure at the top of the isolation post to release it; at the same time, the flat plate needs to be made in different forms to accommodate multi-layer stacking.

[0010] 3) Two mounting components clamping and fixing scheme: Each layer of phase shifter plate requires two mounting components for clamping, which requires a large number of parts and affects assembly efficiency; the single layer of phase shifter plate and mounting components are not in an assembled state, and can only be installed in the required number of layers in the prefabrication process and then put on the final assembly line, or the phase shifter plate and mounting components are assembled one by one in the final assembly process, which is inefficient; in addition, there are many points in the disassembly process, which is also inefficient.

[0011] Therefore, there is an urgent need to provide a solution that can easily achieve multi-layer stacking of multiple flat components to meet the requirements of quick assembly and disassembly. Summary of the Invention

[0012] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a multi-layer stacked structure, an antenna, and an assembly method.

[0013] The first aspect of this application provides a multi-layered structure, including at least two sequentially stacked plate-like members and a support member supported between two adjacent plate-like members;

[0014] The support includes a support body and an elastic latch connected to the side of the support body, and a limiting protrusion is provided on the top of the support body;

[0015] The plate-shaped member is provided with a card hole through which part of the elastic latch passes to engage with the elastic latch, and the bottom of the plate-shaped member is provided with a limiting groove for the limiting protrusion to be inserted.

[0016] The support member is fixedly connected to the plate-shaped member located below the support member to form a plate assembly. The plate assembly and the plate-shaped member located above the support member are detachably connected by the engagement of the elastic latch and the latch hole, and the engagement of the limiting protrusion and the limiting groove.

[0017] Optionally, the elastic latch includes a connecting portion and a hook portion;

[0018] The lower end of the connecting part is bent toward the side of the support body and connected to the side of the support body. A deformation space is formed between the upper end of the connecting part and the side of the support body. The hook part is connected to the upper end of the connecting part.

[0019] Optionally, the number of elastic latches is at least two, with at least two elastic latches respectively connected to two opposite sides of the support body, and the two elastic latches protruding in a direction away from each other.

[0020] Optionally, two support members are provided between two adjacent plate-shaped members, and the two support members are respectively disposed at both ends of the plate-shaped members along the length direction.

[0021] Optionally, the number of elastic latches is at least two, with at least two elastic latches respectively connected to two adjacent sides of the support body, and both elastic latches protruding in a direction away from the support body.

[0022] Optionally, four support members are provided between two adjacent plate-shaped members, and the four support members are respectively disposed at the four corners of the plate-shaped members.

[0023] Optionally, the lower part of the support member is provided with a clearance hole to avoid the elastic latch on the support member located below the support member, and to provide space for operating the elastic latch.

[0024] Optionally, the limiting groove is a through groove that passes through the top and bottom surfaces of the plate-shaped member.

[0025] Optionally, the bottom of the plate-shaped member is provided with an annular rib, and the inner area of ​​the annular rib and the bottom surface of the plate-shaped member together form the limiting groove.

[0026] Optionally, the bottom of the plate-shaped member is provided with a guide post, and the limiting protrusion is provided with a guide hole for the guide post to be inserted.

[0027] Optionally, the support body is provided with an elastic support portion, and the bottom of the plate-shaped member has an abutment surface corresponding to the elastic support portion. The elastic support portion abuts against the abutment surface to provide an upward pushing force to the plate-shaped member.

[0028] Optionally, the elastic support portion includes an arc-shaped support rib, both ends of which are connected to the support body, and the middle part of the arc-shaped support rib bulges upward relative to the support body.

[0029] Optionally, there may be multiple elastic support portions, which are distributed in the peripheral area of ​​the limiting protrusion.

[0030] A second aspect of this application provides an antenna comprising a multi-layered stacked structure as described in any of the above technical solutions.

[0031] A third aspect of this application provides an assembly method for assembling a multi-layered structure as described in any of the above technical solutions, comprising the following steps:

[0032] One of the at least two plate-shaped pieces to be assembled is used as a single plate-shaped piece, and support members are fixed above each of the remaining plate-shaped pieces to form at least one plate assembly.

[0033] The remaining plate assemblies are stacked on top of one of the plate assemblies, and finally a single plate-shaped piece is placed. Each time a plate assembly or a single plate-shaped piece is placed, a pressing force is applied to the topmost plate-shaped piece, so that the elastic latch on the lower support engages with the locking hole on the upper plate-shaped piece. At the same time, the limiting protrusion on the lower support inserts into the limiting groove on the upper plate-shaped piece, thereby achieving the stacking and fixing of two adjacent plate-shaped pieces.

[0034] The technical solution provided in this application has the following advantages compared with the prior art:

[0035] The multi-layered structure, antenna, and assembly method provided in this application utilize a support member between two adjacent plate-shaped components. The support member has elastic latches and limiting protrusions, while the plate-shaped components have corresponding locking holes and limiting grooves. The support member and the plate-shaped component below it are fixedly connected to form a plate assembly. The plate assembly and the plate-shaped component above it are locked together by the engagement of the elastic latches and locking holes. The lateral swaying of the upper and lower layers is limited by the engagement of the limiting protrusions and limiting grooves, thus ensuring the stability of the assembled multi-layered structure. Furthermore, the fixing of each plate-shaped component and its supporting member can be completed in the pre-assembly process, and finally, they can be directly snapped together layer by layer on the final assembly line, resulting in high assembly efficiency. During disassembly, simply push the elastic latches to release them from the locking holes for quick disassembly. If there is an abnormality in an intermediate layer, simply disassemble the corresponding layer using the above disassembly method, while ensuring that the upper and lower layers of the disassembled layer can be matched and assembled, thus meeting the requirements for quick assembly and disassembly.

[0054] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0055] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0056] The following is in conjunction with the appendix Figures 3 to 13 The multilayer stacked structure, antenna, and assembly method of the multilayer stacked structure provided in the embodiments of this application are illustrated by way of example.

[0057] Reference Figure 3 As shown, some embodiments of this application provide a multi-layer stacked structure, including at least two sequentially stacked plate-like members 1 and a support member 2 supported between two adjacent plate-like members 1. That is, by providing a support member 2 between two adjacent plate-like members 1, the multi-layer stacking function of multiple plate-like members 1 is realized.

[0058] Specifically, refer to Figure 6 and Figure 9 As shown, the support member 2 includes a support body 20 and an elastic latch 21 connected to the side of the support body 20. A limiting protrusion 22 is provided on the top of the support body 20.

[0059] Reference Figure 4 and Figure 5 , Figure 7 and Figure 8 As shown, the plate-shaped member 1 is provided with a locking hole 11 for a portion of the elastic latch 21 to pass through and engage with the elastic latch 21, and the bottom of the plate-shaped member 1 is provided with a limiting groove 12 for the limiting protrusion 22 to be inserted.

[0060] The support member 2 is fixedly connected to the plate-shaped member 1 located below the support member 2 to form a plate assembly. The plate assembly and the plate-shaped member 1 located above the support member 2 (or plate assembly) are detachably connected by the cooperation of the elastic latch 21 with the latch hole 11 and the cooperation of the limiting protrusion 22 with the limiting groove 12.

[0061] For example, taking the stacking of two plate-shaped parts 1 as an example, a support member 2 can be fixed on top of one of the plate-shaped parts 1. Specifically, the plate-shaped part 1 and the support member 2 can be fixedly connected by means of screws, rivets, etc., to form a plate assembly. Then, the other plate-shaped part 1 is stacked on top of the plate assembly. Specifically, the other plate-shaped part 1 can be placed on top of the plate assembly, so that the elastic latch 21 on the support member 2 of the lower plate assembly corresponds to the latch hole 11 of the upper plate-shaped part 1. At the same time, the limiting protrusion 22 on the support member 2 of the lower plate assembly corresponds to the limiting groove 12 on the upper plate-shaped part 1. By using the cooperation of the elastic latch 21 and the latch hole 11, the upper and lower plate-shaped parts 1 are locked and fixed. By using the cooperation of the limiting protrusion 22 and the limiting groove 12, the lateral swaying of the upper and lower plate-shaped parts 1 is restricted, thereby ensuring the stability of the upper and lower plate-shaped parts 1 after assembly. During disassembly, simply push the elastic latch 21 to disengage it from the latch hole 11 for quick disassembly.

[0062] For a stack of three or more plate-shaped components 1, one of the plate-shaped components 1 can be used as a single plate-shaped component 1, and support members 2 can be fixed above each of the remaining plate-shaped components 1 to form at least one plate assembly. During assembly, the remaining plate assemblies are stacked sequentially on top of one of the plate assemblies, and finally a single plate-shaped component 1 is placed. Each time a plate assembly or a single plate-shaped component 1 is placed, pressure is applied to the topmost plate-shaped component 1, causing the elastic latch 21 on the lower support member 2 to engage with the latch hole 11 on the upper plate-shaped component 1. At the same time, the limiting protrusion 22 on the lower support member 2 is inserted into the limiting groove 12 on the upper plate-shaped component 1, thereby achieving the stacking and stable fixation of two adjacent plate-shaped components 1. When there is an abnormality in the middle layer, simply push the elastic latch 21 on the support member 2 of the corresponding layer to disengage it from the latch hole 11 of the upper plate-shaped component 1 to disassemble the abnormal middle layer. This also ensures that the upper and lower layers of the disassembled layer can be matched and assembled, thus meeting the requirements of quick assembly and disassembly.

[0063] The multi-layered structure provided in the above embodiments of this application utilizes a support member 2 between two adjacent plate-shaped members 1. The support member 2 is provided with an elastic latch 21 and a limiting protrusion 22, while the plate-shaped members 1 are correspondingly provided with locking holes 11 and limiting grooves 12. The support member 2 and the plate-shaped members 1 located below the support member 2 are fixedly connected to form a plate assembly. The plate assembly and the plate-shaped members 1 located above the support member 2 (or the plate assembly) achieve locking and fixing of the upper and lower layers through the cooperation of the elastic latch 21 and the locking hole 11, and through the cooperation of the limiting protrusion 22 and the limiting groove 12. The cooperation of 2 restricts the lateral swaying of the upper and lower layers, thereby ensuring the stability of the multi-layer stacked structure after assembly; and the fixing of each layer's plate-like component 1 and its upper support component 2 can be completed in the pre-assembly process, and finally, they can be directly pressed layer by layer on the final assembly line, resulting in high assembly efficiency; during disassembly, it is only necessary to push the elastic latch 21 to make it come out of the latch hole 11, which can achieve quick disassembly; if there is an abnormality in the middle layer, it is only necessary to disassemble the corresponding layer according to the above disassembly method, while ensuring that the upper and lower layers of the disassembled layer can be matched and assembled, thereby meeting the needs of quick assembly and disassembly.

[0064] Furthermore, the multi-layer stacked structure provided in the above embodiments of this application allows the support member 2 to be of the same specification. That is, only the support member 2 of the same specification needs to be used to achieve the multi-layer stacking of multiple plate-shaped parts 1, while solving the stability problems such as shaking and offset in multi-layer stacking. The plate-shaped parts 1 and the support member 2 have a unified installation interface, which can be used to achieve docking. During the assembly process, quick assembly and disassembly can be carried out, which can effectively reduce assembly time and reduce production costs. At the same time, it achieves universality from the perspective of material management, which can be mass-produced and reduce material costs.

[0065] It should be noted that the number of support members 2 provided between two adjacent plate-shaped parts 1 can be determined according to the application scenario; the number of elastic latches 21 provided on the support members 2 can also be determined according to the application scenario; correspondingly, the number of latch holes 11 provided on the plate-shaped parts 1 can also be determined according to the application scenario.

[0066] In some embodiments, refer to Figure 6 and Figure 9 As shown, the elastic latch 21 includes a connecting portion 211 and a hook portion 212. The lower end of the connecting portion 211 is bent toward the side of the support body 20 and connected to the side of the support body 20. A deformation space is formed between the upper end of the connecting portion 211 and the side of the support body 20. The hook portion 212 is connected to the upper end of the connecting portion 211. Specifically, the hook portion 212 may protrude relative to the connecting portion 211 in a direction away from the support body 20. Of course, the hook portion 212 may also be provided to protrude relative to the connecting portion 211 in a direction toward the support body 20.

[0067] This design allows the elastic latch 21 to undergo elastic deformation relative to the supporting body 20, thereby ensuring that the latch 212 of the elastic latch 21 passes smoothly through the latch hole 11 on the plate 1. After the latch 212 passes through, the elastic latch 21's rebound prevents the latch 212 from coming out of the latch hole 11.

[0068] During actual assembly, the elastic latch 21 on the support member 2 passes through the latch hole 11 on the plate member 1. During the assembly process, the latch hook 212 of the elastic latch 21 is squeezed by the hole wall of the latch hole 11, which causes the connecting part 211 connected to the latch hook 212 to deform. After the latch hook 212 passes through the latch hole 11, the connecting part 211 rebounds, so that the side of the connecting part 211 (specifically, the side facing away from the support body 20) fits against one side of the hole wall of the latch hole 11, thereby limiting the latch hook 212 on the side of the plate member 1 facing away from the support member 2, preventing the latch hook 212 from coming out of the latch hole 11 of the plate member 1, thereby achieving the locking and fixing of the support member 2 and the plate member 1. Furthermore, during the assembly process of the elastic latch 21 passing through the latch hole 11, the limiting protrusion 22 on the support member 2 is inserted into the limiting groove 12 on the plate member 1, that is, the limiting protrusion 22 on the support member 2 and the limiting groove 12 on the plate member 1 also fit together synchronously.

[0069] In some embodiments, refer to Figures 3 to 6 As shown, there are at least two elastic latches 21, with at least two elastic latches 21 respectively connected to two opposite sides of the support body 20, and the two elastic latches 21 protruding in a direction away from each other. This arrangement ensures the firmness of the assembly between the support member 2 and the plate member 1 by engaging the two elastic latches 21 with the two locking holes 11 on the plate member 1.

[0070] For example, refer to Figures 3 to 6 As shown, each support member 2 includes two elastic latches 21, which are respectively connected to two opposite sides of the support body 20, and the two elastic latches 21 protrude in the direction away from each other.

[0071] In specific implementation, the support body 20 of the support member 2 can be a long strip structure, and two elastic latches 21 can be connected to the two opposite sides of the support body 20 along the length direction. In this way, the distance between the two elastic latches 21 can be increased, thereby correspondingly increasing the distance between the two latch holes 11 on the plate 1, thus ensuring the firmness of the assembly connection between the support member 2 and the plate 1. In addition, when the width (or length) of the plate 1 is relatively short, a small number of support members 2 can be used to achieve a stable support between the upper and lower plate 1.

[0072] In one embodiment, refer to Figure 3As shown, two support members 2 support each adjacent plate-shaped component 1, with the two support members 2 respectively located at both ends of the plate-shaped component 1 along its length. In other words, only two of the above-mentioned support members 2 are needed to achieve stable support between the upper and lower plate-shaped components 1, making assembly and disassembly more convenient.

[0073] In other embodiments, reference is made to Figures 11 to 13 As shown, there are at least two elastic latches 21, with at least two elastic latches 21 respectively connected to two adjacent sides of the support body 20, and both elastic latches 21 protruding in the direction away from the support body 20. This arrangement ensures the firmness of the assembly between the support member 2 and the plate-shaped member 1 by engaging the two elastic latches 21 with the two locking holes 11 on the plate-shaped member 1.

[0074] For example, refer to Figure 11 and Figure 13 As shown, each support member 2 includes two elastic latches 21, which are respectively connected to two adjacent sides of the support body 20, and the two elastic latches 21 protrude in a direction away from each other.

[0075] In specific implementation, the support body 20 of the support member 2 can be a block structure, such as a cube structure, and two elastic latches 21 can be connected to two adjacent sides of the support body 20. This support member 2 can be used to support the corner parts of the plate-shaped member 1. The two elastic latches 21 face the two sides of the plate-shaped member 1 respectively, so as to facilitate the operation of the elastic latches 21 and realize the quick assembly and disassembly of the upper and lower plate-shaped members 1.

[0076] In one embodiment, refer to Figure 11 As shown, four support members 2 are provided between two adjacent plate-shaped components 1, and the four support members 2 are respectively located at the four corners of the plate-shaped component 1. That is to say, four of the above-mentioned support members 2 are required to achieve stable support between the upper and lower plate-shaped components 1.

[0077] Of course, in specific implementations, the number of elastic latches 21 provided on the support member 2 is not limited to two; it can also be set to three or four, or other numbers, depending on the shape and size of the plate member 1. Multiple elastic latches 21 can be connected to the side of the support body 20 and spaced apart from each other.

[0078] In some embodiments, refer to Figure 3 , Figure 6 and Figure 9 As shown, the lower part of the support member 2 is provided with a clearance hole 213 to avoid the elastic latch 21 on the support member 2 located below the support member 2, and to provide space for operating the elastic latch 21.

[0079] Specifically, by providing clearance holes 213 on the support member 2, when multiple layers are stacked, the hook portion 212 of the elastic latch 21 of the lower support member 2 is exactly within the clearance hole 213 of the upper support member 2, thus enabling the function of infinitely stacking multiple layers using only one support member 2. At the same time, the clearance hole 213 provides operable space for pressing the elastic latch 21, allowing for easy release by pressing the elastic latch 21.

[0080] In a specific implementation, the clearance hole 213 can be set at the lower end of the connecting part 211 of the elastic latch 21. That is, the clearance hole 213 corresponds to the position of the elastic latch 21 so that the upper and lower support members 2 can be aligned in the vertical direction.

[0081] Of course, in specific implementation, the upper and lower support members 2 can also be staggered in the vertical direction. In this implementation, clearance holes 213 can be provided in other parts of the support member 2, or clearance holes 213 do not need to be provided on the support member 2.

[0082] In some embodiments, refer to Figures 3 to 5 As shown, the limiting groove 12 is a through groove that passes through the top and bottom surfaces of the plate-shaped member 1. This design facilitates the machining of the limiting groove 12 and also allows for the installation of other structures on the plate-shaped member 1 to be avoided using the limiting groove 12.

[0083] In other embodiments, reference is made to Figure 7 and Figure 8 As shown, the bottom of the plate-shaped member 1 is provided with an annular rib, and the inner area of ​​the annular rib and the bottom surface of the plate-shaped member 1 together form a limiting groove 12. This arrangement can ensure the structural strength of the plate-shaped member 1 and facilitate the design of structures such as guide posts 122 on the bottom surface of the plate-shaped member 1.

[0084] Specifically, refer to Figure 5 , Figure 6 , Figures 8 to 10 As shown, the shape of the limiting protrusion 22 is adapted to the shape of the limiting groove 12. The inner groove wall of the limiting groove 12 is formed as the first limiting surface 121, and the outer wall of the limiting protrusion 22 is formed as the second limiting surface 221. The limiting protrusion 22 is inserted into the limiting groove 12, and the outer wall of the limiting protrusion 22 and the inner groove wall of the limiting groove 12 are in contact with each other. That is, the first limiting surface 121 and the second limiting surface 221 are in contact with each other to restrict the upper and lower plate-shaped parts 1 from swaying laterally.

[0085] It should be noted that, in order to facilitate the insertion of the limiting protrusion 22 into the limiting groove 12, the opening of the limiting groove 12 can be chamfered to form a guide slope, allowing the limiting protrusion 22 to smoothly insert into the limiting groove 12 along the guide slope at the opening. Alternatively, a chamfer can be made at the top periphery of the limiting protrusion 22 to form a guide slope, further facilitating the insertion of the limiting protrusion 22 into the limiting groove 12.

[0086] In some embodiments, refer to Figures 7 to 10 As shown, for ease of assembly, a guide post 122 is provided at the bottom of the plate-shaped component 1, and a guide hole 222 is provided on the limiting protrusion 22 for the guide post 122 to be inserted. During the assembly process of the plate-shaped component 1 and the support component 2, the guide post 122 and the guide hole 222 are first matched and guided, and blind pressing can be achieved for the group of plate assemblies or individual plate-shaped components 1, which effectively improves the assembly efficiency when pressing each layer.

[0087] In some embodiments, refer to Figure 10 As shown, in order to better ensure the stability of the multi-layer stack, and considering the high cost and precision machining of the parts due to tolerance control, the support body 20 is provided with an elastic support part 23. The bottom of the plate-shaped part 1 has an abutment surface 123 corresponding to the elastic support part 23. The elastic support part 23 abuts against the abutment surface 123 to provide an upward resisting force to the plate-shaped part 1.

[0088] In a specific implementation, the bottom surface of the annular rib of the plate-shaped member 1 used to construct the limiting groove 12 can be formed as the abutment surface 123. Specifically, the elastic support part 23 on the support body 20 and the abutment surface 123 on the plate-shaped member 1 are interference fit during assembly. After assembly, the slight deformation of the elastic support part 23 causes the plate-shaped member 1 to be pushed upward, thereby making the elastic latch 21 on the support member 2 more tightly engaged with the plate-shaped member 1, thus ensuring the stability of the connection between the upper and lower plate-shaped members 1.

[0089] In some embodiments, refer to Figure 10 As shown, the elastic support portion 23 includes an arc-shaped support rib, both ends of which are connected to the support body 20. The middle portion of the arc-shaped support rib protrudes upward relative to the support body 20. Specifically, the top of the elastic support rib can be set higher than the top surface of the support body 20. This arrangement ensures that the top of the elastic support rib can abut against the contact surface 123 on the plate-shaped member 1 and provide an upward resisting force to the contact surface 123. In a specific implementation, the annular support rib can be integrally formed on the support member 2.

[0090] In some embodiments, refer to Figure 10As shown, there are multiple elastic support portions 23, which are distributed in the peripheral area of ​​the limiting protrusion 22. By providing multiple elastic support portions 23, it is ensured that the plate-shaped member 1 is uniformly subjected to a resisting force using multiple elastic support portions 23.

[0091] For example, refer to Figure 10 As shown, the support body 20 of the support member 2 is a long strip structure. An elastic latch 21 is connected to each of the two opposite sides of the support body 20 along the length direction. A limiting protrusion 22 is provided on the top of the support body 20. The limiting protrusion 22 is a long strip protrusion structure that is adapted to the shape of the support body 20. Four elastic support parts 23 are provided around the outer area of ​​the limiting protrusion 22 of the support body 20. The four elastic support parts 23 are arranged in pairs on both sides of the limiting protrusion 22 along the width direction.

[0092] Other embodiments of this application provide an antenna including a multi-layered stacked structure as described in any of the above embodiments.

[0093] The antennas provided in the above embodiments of this application have the beneficial effects of the multi-layer stacked structure of any of the above embodiments because they include the multi-layer stacked structure of any of the above embodiments, which will not be repeated here.

[0094] Specifically, the plate-shaped component 1 of the multi-layered structure can be a phase shifter of the antenna; that is, multiple phase shifters of the antenna can be stacked using the above structure. Of course, the plate-shaped component 1 can also be other structural components in the antenna that need to be stacked.

[0095] Furthermore, this multi-layer stacked structure is not limited to antennas, but can also be applied to other products and devices. For example, the multi-layer stacked structure can also be a stack of multiple PCB boards. As long as it does not deviate from the design concept of this application, it should be within the protection scope of this application.

[0096] Further embodiments of this application provide an assembly method for assembling a multi-layered stacked structure as described in any of the above embodiments, comprising the following steps:

[0097] S101, take one of the at least two plate-shaped pieces 1 to be assembled as a single plate-shaped piece 1, and fix the support member 2 above each of the remaining plate-shaped pieces 1 to form at least one plate assembly.

[0098] S102, the remaining plate assemblies are stacked on top of one of the plate assemblies, and finally a single plate-shaped piece 1 is placed. Each time a plate assembly or a single plate-shaped piece 1 is placed, a pressing force is applied to the uppermost plate-shaped piece 1, so that the elastic latch 21 on the lower support 2 engages with the latch hole 11 on the upper plate-shaped piece 1. At the same time, the limiting protrusion 22 on the lower support 2 is inserted into the limiting groove 12 on the upper plate-shaped piece 1, thereby realizing the stacking and fixing of two adjacent plate-shaped pieces 1.

[0099] It should be noted that in step S101, the process of assembling the plate-shaped part 1 and the support part 2 into a plate assembly can be completed in the pre-assembly process; in step S102, the stacking assembly of multiple plate assemblies and a single plate-shaped part 1 can be achieved directly on the final assembly line by pressing layer by layer, which has high assembly efficiency.

[0100] Reference Figure 3 As shown, the following explanation is based on the example of the stacked assembly of three plate-shaped components 1:

[0101] First, one of the three plate-shaped parts 1 to be assembled is taken as a single plate-shaped part 1, and support members 2 are fixed on top of the other two plate-shaped parts 1 respectively to form two plate assemblies.

[0102] Then, one of the plate components is placed as the bottom plate component, and another plate component is placed on top of it. Pressing pressure is applied to the plate component above, so that the elastic latch 21 on the lower support 2 engages with the latch hole 11 on the upper plate 1. At the same time, the limiting protrusion 22 on the lower support 2 is inserted into the limiting groove 12 on the upper plate 1, thereby achieving the stacking and fixing of the two adjacent plate components.

[0103] Finally, a single plate-shaped piece 1 is placed on top of the two stacked and fixed plate assemblies. Pressing pressure is applied to the uppermost plate-shaped piece 1, causing the elastic latch 21 on the lower support 2 to engage with the latch hole 11 on the uppermost plate-shaped piece 1. At the same time, the limiting protrusion 22 on the lower support 2 is inserted into the limiting groove 12 on the uppermost plate-shaped piece 1, thereby achieving the stacking and fixing of the three uppermost plate-shaped pieces 1 and the two lower plate assemblies, thus completing the assembly.

[0104] During disassembly, simply push the elastic latch 21 to disengage it from the latch hole 11 to achieve quick disassembly. If there is an abnormality in the middle layer, simply disassemble the corresponding layer according to the above disassembly method. At the same time, it can also ensure that the upper and lower layers of the disassembled layer can be matched and assembled, thereby meeting the needs of quick assembly and disassembly.

[0105] In summary, the multi-layered structure provided in this application has the following beneficial effects:

[0106] 1. Multiple plate-shaped components can be stacked in multiple layers using only one type of support component, thus solving the stability problems such as swaying and offset after multiple layers are stacked.

[0107] 2. The elastic latches achieve a locking function in the vertical direction between the upper and lower layers. When stacking, it is easy to press down; when disassembly is required, pushing the elastic latches will release the latches, which is convenient and easy to operate; assembly and disassembly are convenient and efficient.

[0108] 3. The above advantages ensure that during later maintenance, the abnormal board components in the middle layer can be extracted at any time without disassembling them layer by layer; and after disassembly, the upper and lower layers of the problematic board components can be seamlessly connected and snapped together without any matching problems.

[0109] 4. The installation interface of the plate-shaped parts and the supporting parts is unified so that they can be connected. During the assembly process, quick assembly and disassembly can effectively reduce assembly time and production costs. At the same time, the material standardization achieves universality, which can be mass-produced and reduce material costs.
