Description

Technical Field

[0001] This application relates to the field of base station antenna technology, and in particular to a radiating element adjustment and installation mechanism, a reflector device, and a base station antenna. Background Technology

[0002] Base station antennas are a crucial component of mobile communication base stations. A base station antenna consists of a reflector and several radiating elements mounted on the reflective surface of the reflector. The layout of these radiating elements directly affects the coverage and quality of the antenna signal. Base station antennas operate in diverse environments, requiring appropriate performance tuning to ensure the antenna layout matches the signal coverage area.

[0003] In related technologies, such as Figure 1 As shown, the radiating element 2' of the base station antenna is usually fixedly installed on the plane of the reflector 1' using fasteners such as screws, rivets, and clips. This fixes the position of the radiating element 2' on the reflector 1'. If the position of the radiating element 2' needs to be adjusted during performance debugging, the reflector 1' needs to be redesigned and the entire base station antenna needs to be reassembled for testing. Adjusting the position of the radiating element 2' is difficult and time-consuming, resulting in long project debugging and testing cycles, long solution finalization time, and low development efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a radiating element adjustment and installation mechanism, a reflector device, and a base station antenna, aiming to at least solve the problems in the prior art where the adjustment of the radiating element position of the base station antenna is difficult and time-consuming, resulting in long project debugging and testing cycles and low development efficiency.

[0005] In a first aspect, this application provides a radiating element positioning and installation mechanism, comprising:

[0009] A locking component is provided on the mounting base, and the locking component is used to lock or unlock the mounting base to the mounting component.

[0017] In one embodiment, the locking assembly includes a locking member, an operating member, and a first elastic member. The locking member is movably disposed on the bottom side of the substrate and is movable relative to the substrate to a locked position and an unlocked position. The operating member is connected to the locking member, and operating the operating member can drive the locking member to move toward the unlocked position. The first elastic member is connected to the locking member and generates a driving force toward the locking member to move toward the locked position. In the locked position, the locking member and the substrate cooperate to clamp opposite sides of the support portion to lock the fixing seat and the mounting member. In the unlocked position, the locking member and the support portion are misaligned to unlock the fixing seat and the mounting member.

[0018] In one embodiment, the locking component further includes a second elastic element disposed between the operating element and the locking element.

[0019] In one embodiment, the mounting component includes two guide rails arranged side by side and spaced apart. Both guide rails are parallel to the preset direction.

This effectively shortens the antenna development cycle, improves development efficiency, and reduces development costs. It effectively solves the problems of difficult and long adjustment cycles of the radiating element position in existing base station antennas, which lead to long project debugging and testing cycles and low development efficiency.

[0050] To explain in detail the technical content, structural features, objectives and effects of this application, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0051] Base station antennas are a crucial component of mobile communication base stations. A base station antenna consists of a reflector and several radiating elements mounted on the reflective surface of the reflector. The layout of these radiating elements directly affects the coverage and quality of the antenna signal. Base station antennas operate in diverse environments. To ensure accurate signal coverage during use, appropriate performance tuning is necessary to achieve a good match between the antenna layout and the signal coverage area.

[0052] Existing base station antennas typically use screws, rivets, clips, and other fasteners to fix the radiating elements onto the reflector plane. This requires corresponding holes to be drilled in the reflector at the radiating element's mounting position. Therefore, radiating element installation is cumbersome, disassembly is difficult, and the elements are easily damaged. Furthermore, the holes in the reflector are fixed and cannot be adjusted, meaning the radiating element's position is fixed. If adjustments are needed during performance testing, the antenna layout must be redesigned, the reflector redesigned, the hole positions adjusted, and the entire base station antenna reassembled for testing. Adjusting the radiating element's position is difficult and time-consuming, leading to long project debugging and testing cycles, extended solution finalization timelines, longer product development cycles, and low development efficiency.

[0053] To solve the above problems, the following will combine... Figures 2 to 12 This application describes the radiating element positioning and installation mechanism, the reflector device, and the base station antenna.

[0054] See Figures 2 to 4 , Figure 2 A front view of the adjustable mounting mechanism for the radiating element in some embodiments of this application is shown. Figure 3 The following are schematic diagrams of the reflector device in some embodiments of this application. Figure 4 The diagram shows a partially enlarged structural schematic of a reflector device in some embodiments of this application. Embodiments of this application provide a radiation unit adjustment and installation mechanism 100, which includes a mounting component 1, a fixing base 2, multiple positioning components 3, and a locking assembly 4. The mounting component 1 is mounted on a reflector 200 and has a supporting portion 11. The supporting portion 11 has a moving channel 12 extending along a preset direction. The fixing base 2 is used to detachably mount the radiation unit 300. The fixing base 2 is configured to be movably supported on the supporting portion 11 along the preset direction and partially housed within the moving channel 12. Multiple positioning components 3 are sequentially arranged within the moving channel 12 along the preset direction. The positioning components 3 are detachably connected to the fixing base 2 to position the fixing base 2. The locking assembly 4 is disposed on the fixing base 2 and is used to lock or unlock the fixing base 2 to the mounting component 1.

[0055] like Figure 2 and Figure 4 As shown, the X direction is the preset direction, the Y direction is the width direction of the mounting part 1, and the Z direction is the height direction of the mounting part 1.

[0056] In this embodiment, the mounting member 1 extends longitudinally, meaning that the mounting member 1 is generally shaped with a length dimension much larger than its width and height dimensions. The preset direction is the length direction of the mounting member 1, meaning that the width and height directions of the mounting member 1 are both perpendicular to the preset direction. The mounting member 1 is provided with a support portion 11, which extends continuously along the preset direction, meaning that the support portion 11 is a continuous support structure. The support portion 11 is provided with a moving channel 12 extending along the preset direction, that is, the support portion 11 and the moving channel 12 are parallel. The mounting member 1 is disposed on the reflector 200, meaning that the mounting member 1 is laid on the reflector 200 along the preset direction, and the preset direction is parallel to the reflective surface of the reflector 200. For example, the preset direction can be the longitudinal direction of the reflector 200.

[0057] The mounting base 2 is detachably mounted on the radiating unit 300, allowing for the replacement of different radiating units 300 according to product development needs. This enables performance tuning of different radiating units 300, providing convenience and flexibility, improving development efficiency, and saving material costs for the mounting base 2. The mounting base 2 can be supported on the bearing part 11, and a portion of the bottom structure of the mounting base 2 can be accommodated within the moving channel 12. Since the bearing part 11 and the moving channel 12 are continuously arranged along a preset direction, the mounting base 2 can move along the bearing part 11, thereby adjusting the mounting position of the mounting base 2 on the bearing part 11. In other words, the mounting position of the mounting base 2 can be adjusted along the preset direction. By adjusting the mounting position of the mounting base 2 on the mounting member 1, the position of the radiating unit 300 on the reflector 200 can be adjusted simultaneously.

[0058] Multiple positioning elements 3 are arranged sequentially in the moving channel 12 along a preset direction. The positioning elements 3 are fixed relative to the mounting element 1 in the preset direction, and thus the position of each positioning element 3 in the preset direction is fixed. The fixing seat 2 is connected to at least one of the multiple positioning elements 3, thereby positioning the fixing seat 2 at the installation position corresponding to the connected positioning element 3, realizing the positioning of the installation position of the fixing seat 2 in the preset direction, so as to position the fixing seat 2, that is, to position the radiation unit 300 on the reflector 200 in the preset direction.

[0059] The locking component 4 is set on the fixed base 2 and located in the moving channel 12. The locking component 4 is used to lock the fixed base 2 to the mounting part 1 or unlock it, so as to lock the fixed base 2 and the mounting part 1 in the normal direction of the reflector 200, ensuring that the fixed base 2 is installed on the mounting part 1 stably and reliably, which facilitates the subsequent performance testing of the radiation unit 300.

[0060] In use, multiple positioning components 3 are assembled into the moving channel 12 and combined with the mounting component 1 to form a whole. The mounting component 1 and the positioning components 3 are fixedly mounted on the reflector 200. The mounting component 1 serves as the base for the radiation unit 300 to be mounted on the reflector 200, limiting the position adjustment range of the radiation unit 300. The radiation unit 300 is fixedly mounted on the fixing base 2. The radiation unit 300 and the fixing base 2 form a whole radiation module. In subsequent operations, the radiation module as a whole performs specific actions to realize the function of adjusting the installation position on the mounting component 1, ultimately realizing the adjustment of the position of the radiation unit 300 on the reflector 200.

[0061] The radiating unit adjustment and installation mechanism 100 of this application embodiment, by setting the mounting component 1 and the fixing seat 2, can adjust the position of the radiating unit 300 on the reflector 200; by setting the positioning component 3 and the locking component 4, the fixing seat 2 can be locked on the mounting component 1 and the installation position of the fixing seat 2 on the mounting component 1 can be positioned, thereby positioning the position of the radiating unit 300 on the reflector 200; moreover, the radiating unit 300 and the fixing seat 2, the fixing seat 2 and the mounting component 1 and the positioning component 3 can be detachably connected, making disassembly and assembly convenient, and the position adjustment of the radiating unit 300 is simple and convenient, realizing the quick installation, disassembly and position adjustment of the radiating unit 300 on the reflector 200, effectively shortening the antenna development cycle, improving development efficiency, reducing development costs, and effectively solving the problems of difficult and long adjustment cycle of the radiating unit position of the base station antenna in the prior art, resulting in long project debugging and testing cycles and low development efficiency.

[0062] Specifically, multiple positioning elements 3 are arranged in a mutually abutting configuration along a preset direction. That is, any two adjacent positioning elements 3 abut against each other, ensuring that the multiple positioning elements 3 are closely arranged within the moving channel 12. This achieves a fixed position of the positioning elements 3 relative to the mounting element 1 in the preset direction, and the close arrangement of the multiple positioning elements 3 in the preset direction improves the positioning accuracy of the positioning elements 3. In some embodiments, such as... Figure 2 and Figure 4 As shown, the moving channel 12 is also provided with a sliding groove 13, which is set parallel to a preset direction; as Figure 5 As shown, the positioning element 3 includes a slide 32, and the slides 32 of multiple positioning elements 3 are sequentially slidably connected in the slide groove 13 so as to arrange the multiple positioning elements 3 along the slide groove 13.

[0063] In this embodiment, a slide groove 13 is provided in the moving channel 12 to install multiple positioning elements 3 into the moving channel 12. The slide groove 13 defines the arrangement direction of the multiple positioning elements 3, and the positioning elements 3 can move along the slide groove 13 so that two adjacent positioning elements 3 can move to close contact, thereby realizing the close arrangement of multiple positioning elements 3, which is beneficial to improving positioning accuracy.

[0064] In some embodiments, such as Figure 2 and Figure 4 As shown, two sliding grooves 13 are arranged side by side in the moving channel 12, and the two sliding grooves 13 are spaced apart along the width direction of the mounting component 1. By setting two sliding grooves 13 in the moving channel 12, two rows of positioning components 3 can be assembled in the moving channel 12. Both rows of positioning components 3 can be detachably connected to the fixed base 2, making the connection between the fixed base 2 and the positioning components 3 more stable and reliable, and the positioning more accurate, which is beneficial to improving the positioning accuracy.

[0065] In some embodiments, the slide block 32 and the slide groove 13 are clearance-fitted to allow two adjacent positioning elements 3 to be staggered. In this embodiment, the staggered arrangement of two adjacent positioning elements 3 means that the projections of the two adjacent positioning elements 3 on a plane perpendicular to a preset direction are misaligned. By setting the slide block 32 and the slide groove 13 to have a clearance fit, there is an installation gap between the slide block 32 and the slide groove 13, causing the two adjacent positioning elements 3 to be staggered in a direction perpendicular to the preset direction. Thus, when the fixed base 2 is connected to one positioning element 3, due to the staggered arrangement, the other adjacent positioning element 3 will prevent the fixed base 2 from moving along the preset direction, ensuring a stable connection between the fixed base 2 and the positioning element 3, preventing slippage, and improving the positioning effect.

[0066] In some embodiments, such as Figure 2 and Figure 4 As shown, the fixing base 2 includes a base plate 21 and a limiting part 22 disposed on the bottom side of the base plate 21. The base plate 21 is supported on the bearing part 11. The limiting part 22 is located in the moving channel 12 and can abut against the bearing part 11 to limit the fixing base 2 in the width direction of the mounting member 1.

[0067] In this embodiment, the substrate 21 has a top side and a bottom side that are opposite to each other. Specifically, when the fixing seat 2 is installed on the mounting member 1, the bottom side of the substrate 21 is supported on the support part 11, and the top side of the substrate 21 is the side opposite to the mounting member 1. The top side of the substrate 21 is used to install the radiation unit 300. By providing a limiting part 22 on the bottom side of the substrate 21 and placing the limiting part 22 within the moving channel 12 and abutting against the support part 11, the shaking of the fixing seat 2 can be limited by the support part 11, thereby limiting the shaking of the radiation unit 300. The radiation unit 300 is more stably and reliably installed on the reflector 200, which facilitates subsequent performance debugging.

[0068] In some embodiments, such as Figure 2 and Figure 5 As shown, the positioning member 3 includes a snap-fit ​​part 31, which is configured to engage with the limiting part 22 to detachably connect the fixing base 2 and the positioning member 3. Specifically, the snap-fit ​​part 31 is connected to the slide 32.

[0069] In this embodiment, by setting the limiting part 22 to engage with the snap-fit ​​part 31, the fixed seat 2 and the positioning part 3 can be quickly connected, realizing the axial pre-fixation of the fixed seat 2 when it is installed on the mounting part 1. This is beneficial for accurate positioning of the installation position and facilitates the subsequent locking connection between the fixed seat 2 and the mounting part 1. It is easy to disassemble and assemble, and improves testing efficiency.

[0070] In some embodiments, such as Figure 5As shown, the locking part 31 is an elastic claw, which includes two opposing elastic tongues 311. One end of the two elastic tongues 311 is connected to the slide 32, and there is a gap between the other ends to form a locking slot 312 between the other ends of the two elastic tongues 311. The end of the limiting part 22 can be engaged with the elastic claw through the locking slot 312. The locking slot 312 is parallel to the sliding direction of the slide 32. That is, when the positioning member 3 is installed on the mounting member 1, the locking slot 312 of the elastic claw is approximately along the preset direction of the mounting member 1.

[0071] Optionally, the elastic claw is made of an elastic material and locks in place by elastic clamping.

[0072] In some embodiments, such as Figure 5 As shown, the elastic latch 311 also has a protruding ridge 313 on its side facing the inside of the latch 312; as Figure 6 , Figure 8 and Figure 9 As shown, grooves 221 are provided on the opposite two sides of the limiting part 22; as Figure 2 As shown, when the limiting part 22 and the engaging part 31 engage, the end of the limiting part 22 engages into the slot 312, and the protruding ridge 313 engages into the corresponding groove 221. With this configuration, the engagement between the limiting part 22 and the engaging part 31 is more secure, and the connection between the fixing base 2 and the positioning member 3 is more stable and reliable.

[0073] In some embodiments, such as Figure 2 and Figure 4 As shown, two limiting portions 22 are provided on the bottom side of the substrate 21, and the two limiting portions 22 are spaced apart along the width direction of the mounting member 1. By providing two limiting portions 22, the two limiting portions 22 can respectively abut against the bearing portions 11 on opposite sides of the moving channel 12, thereby further limiting the shaking of the radiation unit 300 and improving reliability. In addition, the two limiting portions 22 can cooperate with the two rows of positioning members 3 to make the connection between the fixing base 2 and the positioning members 3 more stable and reliable, which is beneficial to providing positioning accuracy.

[0074] In some embodiments, the slide block 32 and the slide groove 13 are clearance-fitted so that the engaging portions 31 of two adjacent positioning members 3 can be staggered. In this embodiment, multiple positioning members 3 are closely arranged in a preset direction. Due to the existence of the installation gap, the engaging portions 31 of two adjacent positioning members 3 are misaligned in a direction perpendicular to the preset direction. Thus, when the limiting portion 22 of the fixing seat 2 is engaged in the engaging portion 31 of a positioning member 3, the engaging portion 31 of the adjacent positioning member 3 will block the movement of the limiting portion 22 due to the misalignment, ensuring that the connection between the fixing seat 2 and the positioning member 3 is stable and will not slip, resulting in a better positioning effect.

[0075] In some embodiments, such as Figure 2 and Figures 6 to 9 As shown, the mounting base 2 also includes a plug-in base 23 disposed in the middle of the substrate 21. The radiation unit 300 is fixed to the plug-in base 23 by snap-fit, thereby fixing the radiation unit 300 to the mounting base 2 and realizing the installation of the radiation unit 300.

[0076] In some embodiments, such as Figure 2 , Figure 7 and Figure 8 As shown, the locking assembly 4 includes a locking member 41, an operating member 42, and a first elastic member 43. The locking member 41 is movably disposed on the bottom side of the substrate 21 and can move relative to the substrate 21 to a locked position and an unlocked position. The operating member 42 is connected to the locking member 41, and operating the operating member 42 can drive the locking member 41 to move toward the unlocked position. The first elastic member 43 is connected to the locking member 41 and generates a driving force toward the locking member 41 to move toward the locked position. In the locked position, the locking member 41 and the substrate 21 cooperate to clamp the opposite sides of the support portion 11 to lock the fixing seat 2 and the mounting member 1. In the unlocked position, the locking member 41 and the support portion 11 are misaligned to unlock the fixing seat 2 and the mounting member 1.

[0077] In this embodiment, the locking member 41 and the supporting part 11 are misaligned, meaning that the projection of the locking member 41 along the height direction of the mounting part 1 is misaligned with the supporting part 11. The supporting part 11 cooperates with the locking member 41 mounted on the base plate 21 to lock and unlock the connection between the fixing seat 2 and the mounting part 1. The fixing seat 2 is also provided with an operating member 42 for switching the locking state and unlocking state of the fixing seat 2. Specifically, the unlocking process is as follows: when the operating member 42 is operated by an external force, it drives the locking member 41 to move toward the unlocking position. When the end of the stroke is reached, the locking member 41 and the supporting part 11 are misaligned, thereby unlocking the fixing seat 2 and the mounting part 1. When the operating member 42 loses external force, the locking member 41 is driven by the first elastic member 43, which can push the locking member 41 to the locking position. The locking member 41 and the base plate 21 cooperate to clamp the opposite sides of the supporting part 11, which can prevent the fixing seat 2 from detaching from the supporting part 11, thereby locking the fixing seat 2 onto the mounting part 1. The locking component 4 has a simple and reliable structure, is easy and convenient to operate, and facilitates quick assembly and disassembly of the mounting base 2, which helps to shorten the antenna development cycle and improve development efficiency.

[0078] In some embodiments, such as Figure 8 As shown, the locking component 4 also includes a second elastic element 44, which is disposed between the operating element 42 and the locking element 41.

[0079] In this embodiment, by providing a second elastic member 44 between the locking member 41 and the operating member 42, the second elastic member 44 can generate a driving force that moves the operating member 42 and the locking member 41 away from each other, thereby keeping the operating member 42 in a released state away from the locking member 41, which facilitates operation.

[0080] Optionally, the second elastic element 44 is an unlocking spring.

[0081] In some embodiments not shown, the locking assembly 4 includes two locking members 41, which are disposed on opposite sides of the bottom side of the substrate 21 to cooperate with the substrate 21 to clamp the support portions 11 on opposite sides of the moving channel 12. By providing two locking members 41, they can cooperate with the support portions 11 on opposite sides of the moving channel 12 to achieve locking and unlocking of the connection between the fixing seat 2 and the mounting member 1. The fixing seat 2 is subjected to balanced force on both sides, resulting in a better locking effect.

[0082] In some embodiments not shown, the locking member 41 is slidably disposed on the bottom side of the substrate 21 so that the locking member 41 can be translated relative to the substrate 21 to the locked position and the unlocked position.

[0083] In other embodiments, such as Figure 7 and Figure 8 As shown, the locking member 41 is rotatably disposed on the bottom side of the substrate 21, so that the locking member 41 can rotate relative to the substrate 21 to a locked position and an unlocked position. Specifically, as Figure 10 As shown, the locking member 41 is a locking lever. The locking member 41 has a locking part 411, an operating part 412, and a rotating connecting part 413. The operating part 412 is located at one end of the locking member 41, the locking part 411 is located at the opposite end of the locking member 41, and the rotating connecting part 413 is located between the operating part 412 and the locking part 411. Figure 7 As shown, the locking member 41 is rotatably connected to the substrate 21 via a rotating connecting part 413. The operating member 42 is connected to the operating part 412 of the locking member 41. Operating the operating member 42 pushes the operating part 412 of the locking member 41 to move. The operating part 412 causes the locking member 41 to rotate relative to the substrate 21 around the axis of the rotating connecting part 413, thereby causing the locking part 411 of the locking member 41 to move from the locked position to the unlocked position. The first elastic member 43 is connected to the locking part 411 of the locking member 41 to generate an elastic force on the locking part 411 from the unlocked position to the locked position. Optionally, a connecting post 414 is also fixedly connected to the locking part 411 of the locking member 41. The connecting post 414 is used to sleeve and install the first elastic member 43.

[0084] In some embodiments, such as Figure 7 and Figure 9As shown, a rotating shaft 24 is provided on the bottom side of the substrate 21, and the rotating shaft 24 serves as the rotation center axis of the locking member 41; the rotating connecting part 413 of the locking member 41 is a bushing, and the rotating connecting part 413 is coaxially sleeved and connected to the rotating shaft 24, thereby rotatably setting the locking member 41 on the bottom side of the substrate 21.

[0085] In some embodiments, such as Figure 9 As shown, a button seat 25, a spring seat 26, and a limiting baffle 27 are provided on the bottom side of the substrate 21. The button seat 25 has a button hole 251, and the spring seat 26 has a through hole 261; Figure 11 As shown, the operating component 42 includes a button 421, a button lever 422, and a button baffle 423. Figures 7 to 8 As shown, button 421 is movably mounted on button base 25. Button hole 251 serves as a guide and limit for button 421. Button 421 is used to operate operating member 42 to achieve quick unlocking. Button rod 422 passes through button hole 251 and through hole 261 and abuts against operating part 412 of locking member 41. Through hole 261 guides and limits button rod 422. Second elastic member 44 is sleeved on button rod 422, with one end abutting against spring seat 26 and the other end abutting against button baffle 423. Second elastic member 44 is in a compressed state. First elastic member 43 is sleeved on connecting post 414, with one end abutting against limiting baffle 27 and the other end abutting against locking part 411 of locking member 41. First elastic member 43 is in a compressed state to keep locking member 41 in a locked state without external force. Limiting baffle 27 limits the end of travel of locking member 41. The operating member 42, together with the button seat 25, the spring seat 26, and the second elastic member 44, forms the unlocking active end; the locking member 41, together with the rotating shaft 24, the limiting baffle 27, and the first elastic member 43, forms the unlocking driven end.

[0086] In some embodiments, such as Figure 2 and Figures 7 to 9As shown, the limiting part 22 is a limiting plate vertically disposed on the bottom side of the substrate 21, and a window 222 is provided on the limiting plate; the locking member 41, the operating member 42, the first elastic member 43 and the second elastic member 44 are all disposed inside the limiting part 22, and the locking part 411 of the locking member 41 is disposed corresponding to the window 222, and the limiting baffle 27 is disposed opposite to the window 222. When button 421 is pressed by external force, the second elastic element 44 is further compressed, and at the same time, button lever 422 pushes locking element 41 to rotate around pivot 24, so that locking part 411 is locked inward to limit part 22. At the same time, connecting column 414 compresses first elastic element 43 to reach the end of the stroke, thereby unlocking fixed seat 2 and mounting part 1. When button 421 loses external force, second elastic element 44 compresses button 421 to return to the initial state, and first elastic element 43 pushes locking part 411 through window 222 to move outward to limit part 22 and abut against the bottom of bearing part 11, thereby locking fixed seat 2 on mounting part 1.

[0087] In some embodiments, such as Figure 2 , Figure 4 and Figure 12 As shown, the mounting component 1 includes two guide rails 10 arranged side by side and spaced apart. Both guide rails 10 are parallel to a preset direction. Each of the two guide rails 10 has a support wall 111 on its opposite side. The two support walls 111 form a bearing portion 11, and the space between the two guide rails 10 forms a moving channel 12. In this embodiment, the support walls 111 of the two guide rails 10 extend along a preset direction. The base plate 21 of the fixing seat 2 is supported on the support walls 111 and can move along the support walls 111 to adjust the installation position of the fixing seat 2 along the preset direction. By using two guide rails 10 laid on the reflector 200, the range of adjustment and support of the radiation unit 300 are formed. The structure is simple and easy to implement, and the manufacturing cost is low.

[0088] In some embodiments, such as Figure 2 , Figure 4 and Figure 12 As shown, the mounting component 1 has two protruding connecting walls 14 on its opposite outer sides. The two connecting walls 14 are symmetrically distributed relative to the moving channel 12 and parallel to a preset direction. The connecting walls 14 are used to support the connection to the reflective surface of the reflector 200. In this embodiment, by setting the connecting walls 14, during installation, a strip opening 201 is opened on the reflector 200, the guide rail 10 is inserted into the strip opening 201, and supported on the reflective surface of the reflector 200 by the connecting walls 14, thus realizing the connection between the mounting component 1 and the reflector 200. The structure is simple, the installation is convenient, and the cost is low.

[0089] Specifically, the connecting wall 14 and the supporting wall 111 are offset in the height direction of the mounting component 1. In this embodiment, the offset of the connecting wall 14 and the supporting wall 111 means that the projections of the connecting wall 14 and the supporting wall 111 on a plane parallel to the height direction of the mounting component 1 are misaligned. By setting the connecting wall 14 and the supporting wall 111 to be offset, specifically, the supporting wall 111 is lower than the connecting wall 14 in the height direction of the mounting component 1. Therefore, when the base plate 21 of the fixing seat 2 is supported on the supporting wall 111, the height of the fixing seat 2 can be reduced, and the installation effect of the radiation unit 300 on the reflector 200 is better.

[0090] Optionally, the thickness of the substrate 21 of the mounting base 2 is less than or equal to the distance between the upper surface of the support wall 111 and the upper surface of the connecting wall 14 in the height direction of the mounting member 1. This arrangement helps to make the upper surface of the substrate 21 of the mounting base 2 flush with the reflective surface of the reflector 200, thereby further improving the installation effect of the radiation unit 300 on the reflector 200.

[0091] like Figure 3 and Figure 4 As shown, this application embodiment also provides a reflector device, including a reflector 200 and a radiation unit adjustment and installation mechanism 100 provided by any of the above embodiments.

[0092] Since the reflector device and the radiation unit adjustment and installation mechanism 100 have the same technical effect, they will not be described in detail here.

[0093] Specifically, such as Figure 3 and Figure 4 As shown, a strip-shaped opening 201 is provided on the reflector 200, and the mounting component 1 of the radiation unit adjustment and installation mechanism 100 is embedded in the strip-shaped opening 201.

[0094] like Figure 3 and Figure 4 As shown, this application embodiment also provides a base station antenna, which includes a radiating element 300 and a reflector device provided by the above embodiment; or, the base station antenna includes a radiating element 300, a reflector 200 and a radiating element adjustment and mounting mechanism 100 provided by any of the above embodiments, wherein the radiating element 300 is mounted on the reflector 200 through the radiating element adjustment and mounting mechanism 100.

[0095] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
