Description

Technical Field

[0001] The present application relates to the field of mobile communication technology, and in particular to a downtilt display component and antenna. Background Art

[0002] To meet the growing demand for wireless communications, the number of base stations in cellular networks has increased. This has led to a high density of antennas, resulting in significant interference between the signals radiated by each antenna. Consequently, in cellular networks, it is often necessary to adjust the downtilt angle of base station antennas to adjust signal coverage and improve communication quality.

[0003] Currently, there are two main methods used in the industry to adjust the downtilt angle of antennas. One method is to adjust the angle of the antenna mounting bracket to change the downtilt angle of the antenna. This method requires workers to go up to the tower for construction, which is time-consuming and labor-intensive. The other method is to adjust the phase of the antenna phase shifter to change the direction of the antenna's beam radiation. This method only requires remote control and electrical adjustment from below the tower, which is very convenient. However, the latter method also introduces construction difficulties because it is difficult to directly obtain the downtilt angle of each base station antenna when deploying the communication network. Therefore, it is necessary to provide a downtilt angle display device to intuitively display the downtilt angle of each base station antenna.

[0004] In the base station antenna industry, competitors have designed a variety of downtilt angle display devices. The long strip transmission identification rod proposed in patent CN214505778U has a scale mark on the surface of the rod, and the transmission identification rod extends out of the lower end cover of the antenna to display the angle. However, the extended part of the long strip transmission identification rod is prone to damage or breakage during storage, transportation, installation, and use, and it is difficult to display the angle intuitively, making it difficult to read and prone to errors. The pointer-type angle display device proposed in patent CN107994339B and patent CN112788874A has a complex structure, is difficult to process and assemble parts, has a high cost, and is prone to malfunctions during use. In addition, the device occupies a large reflector space, which is not conducive to the miniaturization of the antenna.

[0005] Therefore, how to improve the technical defects in the existing technology has always been a problem that ordinary technicians in this field need to solve urgently. Utility Model Content

[0006] The purpose of this application is to provide a downward tilt display component and antenna, which converts the linear motion on the horizontal plane into motion on the vertical plane, thereby solving the problem that the existing downward tilt display device is prone to damage during storage, transportation, installation, and use due to the structure of the antenna end cover extending out.

[0034] The technical effects of this application are:

[0035] 1. This application utilizes a transmission mechanism to convert the linear motion of the phase shifter on the horizontal plane into the rotational motion of an indicator on the vertical plane. The indicator's rotational angle displays the downtilt angle, making it easier for users to quickly read the value and convenient to operate. Furthermore, because the transmission mechanism in this application is located above the drive mechanism, there is no portion extending beyond the antenna end cap. The indicator is also located on the inner surface of the antenna end cap, preventing damage or breakage during storage, installation, and use. More importantly, the downtilt angle display assembly occupies less space, further facilitating antenna miniaturization and enhancing practicality.

[0036] 2. In this application, a guide structure is provided on the steering member, the height of which increases from the first end to the second end. Thus, when the steering member follows the phase shifter in linear motion on a horizontal plane, a transmission member slidably mounted on the guide structure rises and falls under the guidance of the guide structure. Furthermore, because the end of the transmission member, distal from the steering member, is eccentrically mounted on the indicator member, when the transmission member rises and falls, it forms a structure similar to a crank or rocker, thereby driving the indicator member to rotate.

[0037] 3. In the present application, the above-mentioned guide structure can be formed by providing a guide groove on the side wall of the steering member or providing a guide surface on the top of the steering member. The structure is simple and has a small number of parts. It is not only conducive to reducing production costs, reducing the difficulty of processing and assembly and disassembly, and improving production efficiency, but also can reduce possible errors during transmission and improve the accuracy of readings.

[0038] 4. In the present application, by arranging a roller on the transmission part so that it can roll in contact with the guide surface on the steering part, the friction generated between the steering part and the transmission part is effectively reduced, making the relative movement between the transmission part and the steering part smoother and without jamming, which is more conducive to the indicator to display the angle of the downward tilt angle in real time and the reading is accurate.

[0066] In the following description, specific details such as specific system structures and techniques are provided for the purpose of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obstructing the description of the present application with unnecessary details.

[0067] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0068] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0069] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0070] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0071] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various devices in the present application are not absolute but relative. These descriptions are applicable when these devices are in the positions shown in the accompanying drawings. If the descriptions of the positions of these devices change, these directional indications will also change accordingly.

[0072] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0073] According to a specific embodiment provided in this application, see FIG. Figure 1 、 Figure 2 and Figure 5 A downtilt angle display assembly includes an antenna end cap 100, an indicator 200, a drive mechanism 300, and a transmission mechanism 400. The antenna end cap 100 is provided with a viewing window 110 for user observation. The indicator 200 is rotatably mounted on the antenna end cap 100 and located at the viewing window 110. The drive mechanism 300 is used to drive the phase shifter 600 to move, thereby controlling the phase of the phase shifter 600. The transmission mechanism 400 is used to connect the drive mechanism 300 and the indicator 200. When the drive mechanism 300 drives the phase shifter 600 to move, the indicator 200 can rotate relative to the antenna end cap 100 under the drive of the transmission mechanism 400. In this way, the user can observe the rotation angle of the indicator 200 through the viewing window 110 and read the downtilt angle.

[0074] For example, see Figure 3 and Figure 4 The indicator 200 can be a disc or fan-shaped structure, and an arrow mark 702 is provided on the side of the indicator 200 close to the viewing window 110. In this case, a scale line 701 is provided on the side wall of the antenna end cover 100 away from the indicator 200, corresponding to the position above or below the viewing window 110. By observing the angle indicated by the arrow mark 702 after the indicator 200 is rotated, the downtilt angle can be read, which is convenient and quick to operate. Figure 7 and Figure 8 Alternatively, the scale line 701 may be provided on the indicator 200 and the arrow mark 702 may be provided on the antenna end cover 100 . Similarly, the downtilt angle may be read by observing the angle indicated by the arrow mark 702 after the indicator 200 is rotated.

[0075] The arrow mark 702 and the scale line 701 may be screen printed or injection molded on the indicator 200 or the antenna end cover 100 , which is not limited here and is within the scope of protection of this application.

[0076] In one embodiment, see Figure 1 、 Figure 2 、 Figure 5 and Figure 9The transmission mechanism 400 includes a steering member 410 and a transmission member 420. The steering member 410 is connected to the drive mechanism 300. When the drive mechanism 300 drives the phase shifter 600 to move, the steering member 410 can move with the phase shifter 600. Furthermore, the steering member 410 has a first end and a second end in the direction of movement, and a guide structure is provided on the steering member 410. The height of the guide structure increases from the first end to the second end. The transmission member 420 is slidably mounted on the guide structure, and the end of the transmission member 420 away from the steering member 410 contacts or is hinged to the indicator member 200. The transmission member 420 and the indicator member 200 are eccentrically arranged.

[0077] In this embodiment, a guide structure is provided on the steering member 410, the height of which increases from the first end to the second end. This allows the steering member 410 to follow the phase shifter 600 in linear motion on the horizontal plane. The transmission member 420, guided by the guide structure, can rise and fall relative to the steering member 410, thereby converting the linear motion on the horizontal plane into motion on the vertical plane. Furthermore, because the end of the transmission member 420, distal from the steering member 410, is eccentrically positioned relative to the indicator member 200, when the transmission member 420 rises and falls, it forms a crank-like or rocker-like structure, thereby driving the indicator member 200 to rotate, further converting the linear motion on the vertical plane into rotational motion on the vertical plane. This further achieves linkage between the phase shifter 600 and the indicator member 200, allowing the user to obtain the downtilt angle based on the rotation angle of the indicator member 200, making it easier for the user to quickly read the numerical value.

[0078] Compared to the existing method of providing a long strip transmission indicator rod for users to read the downtilt angle, the indicator 200 (the structure for users to read the downtilt angle) in the downtilt angle display assembly provided by this embodiment is provided inside the antenna end cover 100 and does not extend out of the antenna end cover 100 (especially the antenna lower end cover). It will not be damaged or broken during storage, transportation, installation, and use, and has a longer service life and a more reasonable structural setting. Moreover, the downtilt angle display assembly provided by this embodiment converts linear motion on the horizontal plane into rotational motion on the vertical plane by only providing two structures, the steering member 410 and the transmission member 420. Compared with the existing pointer-type angle display device, the number of parts is significantly smaller and the structure is simpler, which effectively reduces the difficulty of processing, forming, assembly and disassembly, reduces the parts processing cost and production line production hours, and improves production efficiency. In addition, the downtilt angle display assembly also occupies less space, is more conducive to antenna miniaturization, and is highly practical.

[0079] The first end is preferably an end of the steering member 410 away from the antenna end cover 100 , and the second end is an end of the steering member 410 close to the antenna end cover 100 .

[0080] In actual production, see Figure 9 and Figure 10The height of the guide structure may vary linearly from the first end to the second end, that is, the guide structure extends in a straight line; or the height of the guide structure may vary nonlinearly from the first end to the second end, for example, see Figure 11 and Figure 12 The guide structure extends along an inwardly concave arc, an outwardly convex arc, or a wavy line, etc., which are not described here one by one, and are all within the scope of protection of this application.

[0081] In one example embodiment, see Figures 9 to 12 The guide structure may specifically include a guide surface 411, which is the top end surface of the steering member 410. That is, one end of the transmission member 420 is in sliding contact with the top end surface of the steering member 410, and the other end is eccentrically disposed with respect to the indicator member 200. When the steering member 410 moves with the phase shifter 600, the transmission member 420 slides relative to the top end surface of the steering member 410, thereby achieving a rise and fall, thereby driving the indicator member 200 to rotate.

[0082] In actual production, a roller 4215 can be provided at one end of the transmission member 420 so that the transmission member 420 is in rolling contact with the top end surface of the steering member 410, while the other end of the transmission member 420 is eccentrically disposed relative to the indicator member 200. This facilitates relative movement between the transmission member 420 and the steering member 410, reduces the risk of jamming, effectively reduces wear and tear between the transmission member 420 and the steering member 410, and prolongs their service life. Furthermore, it also makes it easier for the indicator member 200 to display the downtilt angle in real time, providing more accurate readings.

[0083] For example, see Figure 9 and Figure 10 A guide groove 412 may be provided on the steering member 410 to form the above-mentioned guide structure. The guide groove 412 may be provided on the top end surface of the steering member 410 or on the side wall of the steering member 410. In this case, the transmission member 420 is provided with a claw 4213 that can be locked in the guide groove 412. By making the claw 4213 slide relative to the extending direction of the guide groove 412, the transmission member 420 can be raised and lowered.

[0084] The guide grooves 412 are preferably two in number, one on each side of the steering member 410. Conversely, the transmission member 420 is provided with two latches 4213, each latched within the two guide grooves 412. This stabilizes the relative motion between the rotating member and the transmission member 420. In this embodiment, a clearance groove 4214 is formed between the two latches 4213 to allow clearance for the top portion of the steering member 410, thereby preventing interference between the steering member 410 and the transmission member 420 during relative motion.

[0085] Of course, in actual production, see Figure 9 and Figure 13The bottom of the avoidance groove 4214 can contact the top end surface of the steering member 410, further improving the stability between the steering member 410 and the transmission member 420. That is, the guide structure includes both the guide surface 411 and the guide groove 412, and the top end surface of the steering member 410 that contacts the bottom of the avoidance groove 4214 is the aforementioned guide surface 411.

[0086] Further, see Figure 14 A roller 4215 is provided in the avoidance groove 4214. The roller 4215 is in rolling contact with the guide surface 411, which effectively reduces the friction generated between the steering member 410 and the transmission member 420, so that the relative movement between the transmission member 420 and the steering member 410 is smoother and there is no jamming, thereby reducing the loss between the transmission member 420 and the steering member 410, extending the service life, and being more conducive to the indicator 200 to display the angle of the downward tilt angle in real time, and the reading is accurate.

[0087] In one embodiment, see Figure 9 The transmission member 420 includes a first connecting rod 421 and a second connecting rod 422. One end of the first connecting rod 421 is hinged to the second connecting rod 422. The other end of the first connecting rod 421 is provided with a docking portion for docking with the guide structure, and the end of the second connecting rod 422 away from the first connecting rod 421 is hinged to the indicator 200.

[0088] In this embodiment, a first connecting rod 421 and a second connecting rod 422 are arranged to be hinged with each other, so that when the first connecting rod 421 is raised and lowered by the guide structure, the second connecting rod 422 can form a crank and rocker structure, thereby converting the linear motion into rotational motion and transmitting it to the indicator 200, thereby realizing the rotation of the indicator 200.

[0089] The docking portion may specifically include the claws 4213 and rollers 4215 provided in the aforementioned embodiments. For example, the claws 4213 are disposed in the guide grooves 412 to guide the first connecting rod 421 to move relative to the steering member 410 along the direction in which the guide grooves 412 extend; the rollers 4215 roll in contact with the guide surfaces 411 to guide the first connecting rod 421 to move relative to the steering member 410 on the guide surfaces 411. Details will not be given here, as all details fall within the scope of protection of this application.

[0090] Specifically, see Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 and Figures 13 to 15A round shaft 703 is provided at one end of the first connecting rod 421 away from the steering member 410, and a hinge hole 704 is provided at one end of the second connecting rod 422. The round shaft 703 is passed through the hinge hole 704 to realize the hinge connection between the first connecting rod 421 and the second connecting rod 422. Relatively speaking, a circular shaft 703 is also provided at one end of the second link 422 away from the first link 421, and two hinge holes 704 are provided on the indicator 200. One of the two hinge holes 704 serves as the rotation center of the indicator 200, for the circular shaft 703 on the inner wall of the antenna end cover 100 to pass through, so that the indicator 200 is rotatably installed on the antenna end cover 100, and the other of the two hinge holes 704 is used for the circular shaft 703 on the second link 422 to pass through, so that the indicator 200 and the second link 422 are hinged. At this time, the second link 422 forms a crank or rocker structure, driving the indicator 200 to rotate around the circular shaft 703 on the antenna end cover 100.

[0091] Of course, in actual production, the positions of the circular shaft 703 and the hinge hole 704 can be interchanged, which is not limited here and is within the scope of protection of this application.

[0092] Preferably, see Figure 1 、 Figure 5 and Figure 9 The antenna end cap 100 is also provided with a vertical guide rail 120. In this case, the first connecting rod 421 is provided with a slider 4216 that can be slidably mounted on the vertical guide rail 120. The vertical guide rail 120 is used to guide the first connecting rod 421 in the vertical direction, further improving the stability of the transmission mechanism 400 and facilitating the improvement of the angular display accuracy of the downtilt angle display assembly. The vertical guide rail 120 can be installed as a separate component on the inner sidewall of the antenna end cap 100, or it can be integrated into the inner sidewall of the antenna end cap 100 during production, both of which are within the scope of protection of this application.

[0093] Specifically, see Figure 9 、 Figure 13 and Figure 14 The first connecting rod 421 includes a first rod portion 4211 and a second rod portion 4212 arranged at an angle. The docking portion is provided at the end of the first rod portion 4211 away from the second rod portion 4212. The slider 4216 is provided at the end of the second rod portion 4212 away from the first rod portion 4211. In this embodiment, the circular shaft 703 on the first connecting rod 421 can be provided on the slider 4216, so that the slider 4216 is hingedly connected to the second connecting rod 422, thereby achieving a hinged connection between the first connecting rod 421 and the second connecting rod 422.

[0094] In one example embodiment, see Figure 9 and Figure 16The indicator member 200 can also be rotatably mounted on the vertical guide rail 120 and fixed to the inner wall of the antenna end cover 100 via the vertical guide rail 120. For example, a circular shaft 703 is provided at the top of the vertical guide rail 120. One of the two hinge holes 704 on the indicator member 200 allows the circular shaft 703 to pass through, thereby rotatably mounting the indicator member 200 on the vertical guide rail 120. At the same time, the other of the two hinge holes 704 on the indicator member 200 allows the circular shaft 703 on the second connecting rod 422 to pass through, thereby achieving an articulated connection between the second connecting rod 422 and the indicator member 200.

[0095] Specifically, see Figure 17 The drive mechanism 300 includes a motor box 310 and a shift transmission box 320. The motor box 310, the shift transmission box 320, and the phase shifter 600 are all mounted on the reflector 500. The motor box 310 is used to drive the shift transmission box 320, which is connected to the phase shifter 600 to move the phase shifter 600, thereby changing the downtilt angle of the antenna. The motor box 310 is provided with a power output shaft 311 and a motor connector 312. The motor connector 312 is used to connect to a signal source to control the rotation of the motor in the motor box 310. The power output shaft 311 cooperates with the shaft sleeve 322 on the shift transmission box 320 to convert the motor's rotational motion into linear motion and output it to the phase shifter 600, thereby achieving linear motion of the phase shifter 600 on the horizontal plane.

[0096] Preferably, an installation station 321 is provided at the top of the shift transmission box 320 for fixing the steering member 410, and the installation station 321 can move linearly relative to the shift sensor. When the motor box 310 drives the shift transmission box 320 to control the phase of the phase shifter 600, the installation station 321 can move with the phase shifter 600, thereby driving the steering member 410 to move with the phase shifter 600.

[0097] Specifically, the shift transmission box 320 is equipped with a first transmission module for driving the phase shifter 600 and a second transmission module for driving the installation station 321. When the motor in the motor box 310 rotates, the first and second transmission modules operate simultaneously to drive the phase shifter 600 and the installation station 321 to move linearly in the same direction. This achieves synchronized movement of the steering member 410 and the phase shifter 600, improving the accuracy of angle display. Of course, in actual production, the same transmission module can also be used to drive the movement of the phase shifter 600 and the installation station 321. These details are not detailed here, as they are all within the scope of protection of this application.

[0098] In this embodiment, by setting the steering member 410 at the top of the shift transmission box 320, the entire transmission mechanism 400 can be integrated in the upper area of ​​the shift transmission box 320, without occupying the planar space of the reflector 500, which is conducive to the miniaturization of the antenna, and the structural setting is more reasonable and practical.

[0099] Further, see Figure 18 A mounting member 413 is provided at the bottom of the steering member 410, and the installation station 321 includes a fixed plate 3211 and side plates 3212 provided on opposite sides of the fixed plate 3211. The fixed plate 3211 and the side plates 3212 together form a placement groove 3213 for placing the mounting member 413, and a plurality of clips 3214 are provided on the side plates 3212 for clamping the mounting member 413 in the placement groove 3213.

[0100] This embodiment provides two side panels 3212, which can better limit the lateral displacement of the mounting member 413. At the same time, by further providing a buckle 3214 on the side panel 3212 to fix the mounting member 413, not only can the mounting member 413 be stably fixed in the placement groove 3213, but also the steering member 410 can be prevented from being separated from the installation station 321 due to vibration during the movement. The structure has high stability, which is conducive to improving the accuracy of the downtilt angle display.

[0101] In addition, in this embodiment, at least one positioning pin 3216 can be further provided on the fixing plate 3211, and a positioning hole 4131 suitable for the positioning pin 3216 to pass through can be opened on the mounting member 413. The steering member 410 can be precisely positioned by the cooperation between the positioning pin 3216 and the positioning hole 4131. At the same time, the relative displacement between the steering member 410 and the mounting station 321 is limited, thereby further improving the accuracy of the downward tilt angle display. The structural setting is reasonable and practical.

[0102] Specifically, see Figure 9 The fixed plate 3211, facing the shifting transmission box 320, is provided with a plurality of tooth blocks 3215 arranged in a straight line, forming a rack structure. Furthermore, the second transmission module within the shifting transmission box 320, which drives the installation station 321, is a gear module that meshes with the rack structure. When the motor within the motor box 310 rotates, the gear module meshes with the fixed plate 3211, driving the fixed plate 3211 to move, thereby driving the steering member 410 to follow the phase shifter 600.

[0103] The present application also provides an antenna, which may specifically include a phase shifter 600 , a reflector 500 and the downtilt display assembly provided in any of the above embodiments, wherein the phase shifter 600 and the downtilt display assembly are both mounted on the reflector 500 .

[0104] In a preferred embodiment, see Figure 1 and Figure 5 The antenna end cover 100, motor box 310 and shift control box in the downtilt display assembly are all fixed on the reflector 500, while the transmission mechanism 400 is installed above the motor box 310 and the shift control box, especially the steering member 410, which is fixed to the shift control box by sliding the mounting station 321 set at the top of the shift control box, without occupying the plane space of the reflector 500, which is more conducive to the miniaturization of the antenna.

[0105] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0106] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be noted that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be considered as the scope of protection of the present application.
