[0033] See also Figure 2-8An embodiment of the utility model provides a support structure 1 for an isolation strip 2, which is used to fix the isolation strip 2 on a reflective plate 3. The support structure 1 includes a main body, which has a first side; along the extension direction of the main body, a plurality of first fixing structures are arranged at intervals on the first side, and the isolation strip 2 is provided with a second fixing structure, which is used to be connected to the first fixing structure so that the isolation strip 2 is fixedly assembled at different positions in the extension direction of the main body; the main body has an end portion, and the end portion is mounted on the reflective plate 3.
[0034] In the embodiment of the utility model, a plurality of first fixing structures are arranged at intervals along the extension direction of the main body of the support structure 1, and the second fixing structure can be connected to any one of the first fixing structures, so that the isolation strip 2 can be fixedly assembled at different positions in the extension direction of the support structure 1, thereby realizing the position adjustment of the isolation strip 2. In addition, the main body has an end, and the end is mounted on the reflective plate 3, that is, the extension direction of the main body is perpendicular to the reflective plate 3, thereby realizing the vertical installation of the support structure 1 on the reflective plate 3. Therefore, the isolation strip 2 can be fixedly assembled on the reflective plate 3 through the support structure 1.
[0035] The embodiment of the utility model supports and fixes the isolation strip 2 through the support structure 1, so that the isolation strip 2 is fixed relative to the reflective plate 3, thereby meeting the isolation requirements, and no PCB substrate and metal strip line are required, thereby reducing costs. Furthermore, the embodiment of the utility model can also achieve an adjustable height of the isolation strip 2 relative to the reflective plate 3. By adjusting the isolation strip 2 at different positions on the support structure 1, the isolation requirements of different heights can be met.
[0036] For further information, see Figure 3 and Figure 6 The first fixing structure includes a snap-fitting structure 11 disposed on the first side, and the second fixing structure is used for snap-fitting connection with the snap-fitting structure 11.
[0037] Specifically, the second fixed structure can be arranged in a structure that cooperates with the snap-connection structure 11 to achieve a snap-connection between the first fixed structure and the second fixed structure. Whether it is an assembly process or a disassembly process, the snap-connection method is easy to operate, thereby facilitating the adjustment operation of the isolation strip 2 at different positions of the support structure 1 and improving the user experience.
[0038] For further information, see Figure 3 , Figure 6 and Figure 7The clamping structure 11 includes a first protruding plate 111, a second protruding plate 112, a first protruding block 113 and a second protruding block 114; the first protruding plate 111 and the second protruding plate 112 both protrude from the first side, and the first protruding plate 111 and the second protruding plate 112 are arranged at intervals; the first protruding block 113 is arranged on the side of the first protruding plate 111 away from the second protruding plate 112, and a preset gap exists between the side of the first protruding block 113 close to the body and the first side; the second protruding block 114 is arranged on the side of the second protruding plate 112 away from the first protruding plate 111, and a preset gap exists between the side of the second protruding block 114 close to the body and the first side.
[0039] Specifically, the clamping structure 11 includes a first raised plate 111 and a second raised plate 112, and a first raised block 113 and a second raised block 114 are correspondingly arranged on opposite sides of the first raised plate 111 and the second raised plate 112, and the first raised block 113 is close to or arranged at the free end of the first raised plate 111, and the second raised block 114 is close to or arranged at the free end of the second raised plate 112, and both have a certain gap with the first side. The second fixing structure is an assembly hole opened in the main body of the isolation strip 2. Therefore, the first raised plate 111 and the second raised plate 112 can be inserted into the assembly hole, and the main body of the isolation strip 2 can be clamped in the gap between the first raised block 113 and the first side, and the gap between the second raised block 114 and the first side, so as to limit the isolation strip 2 from moving away from the main body.
[0040] In addition, since the snap-fit structure 11 is formed by the first raised plate 111 and the second raised plate 112 spaced apart, during the assembly process, the first raised plate 111 and the second raised plate 112 can be pressed to bring the two closer to each other, thereby facilitating the insertion of the first raised plate 111 and the second raised plate 112 into the assembly hole and reducing the difficulty of assembly.
[0041] In some embodiments, the first protruding plate 111 and the second protruding plate 112 are arranged at intervals along the extension direction of the body. In other embodiments, the first protruding plate 111 and the second protruding plate 112 are arranged at intervals along the extension direction perpendicular to the body.
[0042] In some embodiments, the clamping structure 11 may be a columnar structure protruding from the first side and in an arrow shape, and a snap connection between the clamping structure 11 and the second fixing structure may also be achieved.
[0043] Furthermore, the first protruding block 113 is provided with a first inclined surface, which is inclined from the surface of the first protruding plate 111 toward the direction close to the body; the second protruding block 114 is provided with a second inclined surface, and the first inclined surface and the second inclined surface are symmetrically arranged.
[0044] Specifically, in some embodiments, the first protruding block 113 is disposed at the free end of the first protruding plate 111, and the first inclined surface extends outward from the surface of the free end of the first protruding plate 111 (the surface of the first protruding plate 111 on the side away from the second protruding plate 112), and is inclined in the direction close to the body. Similarly, the second inclined surface extends outward from the surface of the free end of the second protruding plate 112 (the surface of the second protruding plate 112 on the side away from the first protruding plate 111), and is inclined in the direction close to the body, so that the first inclined surface and the second inclined surface are arranged opposite to each other. Due to the provision of the first inclined surface and the second inclined surface, the clamping structure 11 is arrow-shaped, and the head is exposed to the body, and the tail is connected to the first side. During the assembly process, the head of the clamping structure 11 first contacts the assembly hole, so that the first protruding plate 111 and the second protruding plate 112 are conveniently inserted into the assembly hole, thereby reducing the difficulty of assembly.
[0045] In other embodiments, the first protruding block 113 is arranged in the middle or upper middle part of the first protruding plate 111, and the first inclined surface is arranged correspondingly. Similarly, the second inclined surface is arranged symmetrically, which can also reduce the difficulty of assembly.
[0046] For further information, see Figure 4 and Figure 6 The first fixing structure also includes a positioning structure 12 and a limiting member 13; the second fixing structure is used to be connected to the positioning structure 12; the positioning structure 12 is arranged on the first side, and along the extension direction of the main body, at least one of the two sides of the positioning structure 12 is provided with a snap-connecting structure 11; the snap-connecting structure 11 is snap-connected with the limiting member 13, and the isolation strip 2 is snap-connected between the limiting member 13 and the main body.
[0047] Specifically, the second fixing structure can be set as a structure that cooperates with the positioning structure 12, and the second fixing structure is connected to the positioning structure 12, so that positioning can be achieved. Since the peripheral side of the positioning structure 12 is provided with a snap-fit structure 11. When the second fixing structure is connected to the positioning structure 12, and the position limiting member 13 and the snap-fit structure 11 are snap-fitted, the isolation strip 2 can be snap-fitted between the position limiting member 13 and the body, thereby achieving fixed assembly of the isolation strip 2 and the support structure 1.
[0048] In some embodiments, along the extension direction of the body, a plurality of positioning structures 12 and a plurality of snap-fit structures 11 are alternately arranged, that is, there are snap-fit structures 11 on both sides of the positioning structure 12, so that the user can choose the limiter 13 to snap-fit with one of the snap-fit structures 11. Exemplarily, along the extension direction of the body, the center distance between the two closest snap-fit structures 11 is 11 mm, and the center distance between the closest snap-fit structure 11 and the positioning structure 12 is 5.5 mm. In other embodiments, along the extension direction of the body, the center distance between the two closest snap-fit structures 11 can be other dimensions N1, and the center distance between the closest snap-fit structure 11 and the positioning structure 12 can also be other dimensions N2. Due to the alternating arrangement, there is a relationship between the two: N1=2N2.
[0049] In some embodiments, part of the positioning structures 12 and part of the snap-fitting structures 11 are alternately arranged along the extension direction of the body. One positioning structure 12 and another positioning structure 12 may be arranged adjacent to each other, and snap-fitting structures 11 are arranged on the sides away from each other of the two positioning structures 12 .
[0050] In some embodiments, along the extension direction of the body, the spacing between the first first fixing structure (which may be the positioning structure 12 or the snap-fit structure 11) and the last first fixing structure (which may be the positioning structure 12 or the snap-fit structure 11) is 23mm-56mm, that is, the supportable height of the support structure 1 is 23mm-56mm, specifically 23, 25, 28, 30, 32, 35, 38, 40, 42, 45, 48, 50, 52, or 56mm, etc. Support structures 1 with different supportable heights can be produced according to actual needs to meet diverse needs.
[0051] For further information, see Figure 4 and Figure 6 The positioning structure 12 includes a protruding column 121 protruding from the first side, and the second fixing structure is used to be sleeved on the protruding column 121; the limiting member 13 includes a main body and at least one connecting portion 131; the main body is provided with a through hole 130, and the through hole 130 is sleeved on the clamping structure 11; the connecting portion 131 is connected to the main body, and the isolation strip 2 is clamped between the connecting portion 131 and the main body.
[0052] Specifically, the second fixing structure can be an assembly hole opened in the main body of the isolation strip 2, and the protruding column 121 can be inserted into the assembly hole, so that the isolation strip 2 can be positioned on the support structure 1. In addition, the first protruding plate 111 and the second protruding plate 112 of the clamping structure 11 can be inserted into the through hole 130 of the main body of the limiting member 13 to achieve the snap connection between the clamping structure 11 and the limiting member 13. During assembly, the assembly hole of the isolation strip 2 is first sleeved on the protruding column 121, and then the through hole 130 of the main body is sleeved on the first protruding plate 111 and the second protruding plate 112 of the clamping structure 11, so that the limiting member 13 and the clamping structure 11 are snap-connected, and at the same time, the connecting portion 131 of the limiting member 13 can be located on the side of the isolation strip 2 away from the first side, that is, the isolation strip 2 is snap-connected between the connecting portion 131 and the first side of the body.
[0053] In some embodiments, the number of the connecting portion 131 may be one, and the limiting member 13 is snap-connected to the snap-connecting structure 11 in only one direction.
[0054] In some embodiments, a plurality of connecting parts 131 are provided at intervals around the main body, so that the main body and the snap-fitting structure 11 can be snap-fitted in multiple directions, and the isolation strip 2 can be snap-fitted between the connecting part 131 and the first side of the main body. When the snap-fitting structure 11 is provided on both sides of the positioning structure 12, the stopper 13 can be snap-fitted with the snap-fitting structure 11 on any side of the positioning structure 12. Specifically, the number of connecting parts 131 can be 2, 3, 4 or 5, etc.
[0055] For further information, see Figure 6 and Figure 7 A protruding structure 14 is protruded from the end, and a clamping portion 15 is protruded from the periphery of the protruding structure 14. The clamping portion 15 is arranged at one end of the protruding structure 14 away from the end.
[0056] Specifically, a protruding structure 14 is protruded from the end of the main body of the support structure 1, and a clamping portion 15 is also protruded from the side of the protruding structure 14. The clamping portion 15 is arranged at the end of the protruding structure 14 away from the end, and there is a certain gap between the clamping portion 15 and the end. Correspondingly, a mounting hole is arranged on the main body of the reflector 3. During assembly, the protruding structure 14 and the clamping portion 15 can be inserted into the mounting hole, and the main body of the reflector 3 can be clamped in the gap between the clamping portion 15 and the end, so that the support structure 1 and the reflector 3 can be snap-fitted, which is convenient to operate.
[0057] For further information, see Figure 7 An elastic plate 16 is also provided at the end, and the protruding structure 14 protrudes from the side of the elastic plate 16 away from the first fixed structure; the elastic plate 16 can be deformed by a predetermined deformation amount along the extension direction of the main body, and when the end is assembled on the reflecting plate 3, the elastic plate 16 is attached to the reflecting plate 3.
[0058] Specifically, the elastic plate 16 is arranged between the end and the protruding structure 14. The main body of the reflector 3 is clamped between the clamping portion 15 and the elastic plate 16. In the initial state, both ends of the elastic plate 16 are bent toward the protruding structure 14 by 1-3°, such as 1°, 2° or 3°, etc. When the support structure 1 and the reflector 3 are connected by snapping, the elastic plate 16 will be deformed in a direction away from the protruding structure 14 under the action of the reflector 3, so that the elastic plate 16 and the reflector 3 can fit together, which can play a role in preventing loosening.
[0059] For further information, see Figure 6 and Figure 7 , protrusions 17 are provided at both ends of the elastic plate 16, and the protrusions 17 are provided on the side of the elastic plate 16 away from the end. Correspondingly, the reflective plate 3 is provided with two card slots. When the support structure 1 and the reflective plate 3 are snap-connected, the protrusions 17 will be snapped into the card slots, which can further provide the connection stability of the support structure 1 and the reflective plate 3.
[0060] For further information, see Figure 8 The body also has a second side arranged opposite to the first side, and a marking structure 18 corresponding to the first fixing structure is arranged on the second side, and the marking structure 18 is used to display the position information of the fixing structure in the extension direction of the body.
[0061] Specifically, the marking structure 18 may correspond to the snap-fit structure 11 and / or the fixing structure.
[0062] In some embodiments, along the extension direction of the main body, the positioning structure 12 and the clip structure 11 are alternately arranged, and the first fixed structure is the clip structure 11. The marking structure 18 can be Arabic numerals. Exemplarily, on the second side of the main body, corresponding to the position of the clip structure 11, Arabic numerals are arranged in sequence from the first clip structure 11 to the last clip structure 11. If there are four clip structures 11 in total, a total of four numbers are arranged, namely 1, 2, 3, and 4. In addition, the distance between the two closest clip structures 11, and the distance between the closest clip structure 11 and the positioning structure 12 are all known, that is, the position information of each number on the support structure 1 is known. When the isolation strip 2 is assembled to any clip structure 11 or any positioning structure 12, the corresponding position information of the isolation strip 2 can be obtained, thereby guiding the assembly.
[0063] In some embodiments, the marking structure 18 may be distance information, which may be distance information from the setting position of the marking structure 18 to the end of the main body, which may also guide assembly and is more intuitive and clear.
[0064] For further information, see Figure 2-8An antenna comprises an isolation strip 2, a reflection plate 3, and a support structure 1 as described above, wherein the support structure 1 is vertically mounted on the reflection plate 3, and the isolation strip 2 is fixedly mounted at different positions in the extension direction of the main body.
[0065] Specifically, the extension direction of the isolation strip 2 is perpendicular to the extension direction of the body. When the isolation strip 2 with a certain length is assembled on the reflector 3, at least one supporting structure 1 is required, and at least one assembly hole can be opened in the length direction of the isolation strip 2. If multiple assembly holes are opened in the length direction of the isolation strip 2 at intervals, correspondingly, multiple supporting structures 1 are arranged at intervals along the length direction of the isolation strip 2. The spacing between the multiple supporting structures 1 on the reflector 3 can be adjusted to adapt to isolation strips 2 of different lengths and meet the isolation requirements of the low-frequency oscillator of the base station antenna.
[0066] Also, see Figure 3 and Figure 4 The isolation strip 2 can be a sheet metal isolation strip 2, and the width of the sheet metal isolation strip 2 is relatively narrow. At this time, only one assembly hole is set in the width direction of the isolation strip 2. The assembly hole can be assembled and connected with the snap-on structure 11, or can be assembled and connected with the positioning structure 12. In this case, it is necessary to cooperate with the limit member 13.
[0067] For other embodiments, see Figure 5 The isolation strip 2 can also be a PCB isolation strip 2. The PCB substrate has a certain width (but the width is smaller than the PCB substrate in the related art). At the same time, a metal layer that plays an isolation role is also provided on one side of the PCB substrate. At this time, the PCB isolation strip 2 has two assembly holes in the width direction, one on the PCB substrate and the other on the metal layer. At this time, one assembly hole is assembled and connected with the clamping structure 11, and the other assembly hole is assembled and connected with the positioning structure 12. At this time, the limiter 13 is not required to cooperate.
[0068] During assembly, first, assemble the protruding structure 14 of one support structure 1 into the mounting hole of the reflector 3, and snap the protruding block 17 of the support structure 1 into the slot of the reflector 3, so that the body is vertically arranged on the reflector 3. If multiple support structures 1 are required, assemble them in the same way. Figure 3 , the assembly hole of the isolation strip 2 is sleeved on the clamping structure 11; or, see Figure 4 , the assembly hole of the isolation strip 2 is sleeved on the positioning structure 12, and then the through hole 130 of the limiting member 13 is sleeved on the clamping structure 11, and the main body of the isolation strip 2 is clamped between the limiting member 13 and the first side; or, see Figure 5 One of the assembly holes of the isolation strip 2 is sleeved on the clamping structure 11 , and the other assembly hole is assembled and connected with the positioning structure 12 .
[0069] The embodiment of the utility model supports and fixes the isolation strip 2 through the support structure 1, so that the isolation strip 2 is fixed relative to the reflective plate 3, thereby meeting the isolation requirements and having low cost. Furthermore, the embodiment of the utility model can also achieve an adjustable height of the isolation strip 2 relative to the reflective plate 3. By adjusting the isolation strip 2 at different positions on the support structure 1, the isolation requirements of different heights can be met.
[0070] It can be understood that the support structure 1 of the embodiment of the utility model is suitable for the boundary isolation strip 2 of the antenna, and is also suitable for the support requirements of the isolation strip 2 at other positions of the antenna.
[0071] For further information, see Figure 2 The antenna also includes a low-frequency array and a vertical isolation plate arranged on the reflective plate. The embodiment of the utility model fixes the isolation strip on the reflective plate through a supporting structure without affecting the use of the vertical isolation plate, thereby meeting the isolation requirements of the low-frequency array.
[0072] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
