Description

Technical Field

[0001] The present disclosure relates to the technical field of electrically tunable antennas, and particularly to an electrically tunable antenna downtilt display device and an antenna. Background Art

[0002] As an important device for receiving and transmitting electromagnetic waves, a base station antenna has an important impact on the coverage quality of communication signals. The coverage range and quality of signals are closely related to the downtilt angle of the antenna, and accurately adjusting the downtilt angle of the antenna is an important measure to optimize the network coverage quality.

[0003] In order to enable an operator to intuitively see the angle of the electrically tunable antenna downtilt, the publication number CN107994339A provides an electrically tunable antenna downtilt indicating device, including a push-pull rod and a helical tube. One end of the helical tube is provided with a pointer and a scale disk. A pin is arranged on the push-pull rod, and a helical groove is arranged on the inner side wall of the helical tube. When the push-pull rod is inserted into the helical tube, the pin is connected to the helical groove. When the drive mechanism drives the push-pull rod to linearly move in the helical tube, the pin slides along the helical groove, thereby driving the helical tube to rotate, and the pointer rotates relative to the scale disk. At this time, the angle indicated by the pointer is the electrically tunable antenna downtilt.

[0004] However, the above-mentioned electrically tunable antenna downtilt indicating device needs to be provided with a helical groove inside the helical tube, resulting in a relatively large manufacturing difficulty. Summary of the Invention

[0008] One end of the rotating sleeve has an opening for the transmission rod to extend into the rotating sleeve, and a groove for cooperating with the helical protrusion is arranged at the opening, so that when the transmission rod linearly moves, the rotating sleeve is driven to rotate; the other end of the rotating sleeve has an angle indicating needle, the scale disk is arranged at the other end of the rotating sleeve, and the scale disk has angle markings. The electrically tunable antenna downtilt can be displayed through the relative position of the angle indicating needle on the scale disk.

A groove for cooperating with the spiral protrusion is provided at the opening of the rotating sleeve where the drive rod can extend into the rotating sleeve.

[0039] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0040] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0041] As an important device for receiving and transmitting electromagnetic waves, the base station antenna has an important impact on the coverage quality of communication signals. The coverage range and coverage quality of the signal are closely related to the tilt angle of the antenna, and accurately adjusting the tilt angle of the antenna is an important measure to optimize the network coverage quality. Generally, the electronic tilt angle of the antenna is adjusted through an adjusting device.

[0042] Reference Figure 1 and Figure 2 As shown, the adjusting device for adjusting the downtilt angle of the electrically adjustable antenna may specifically include: a driving assembly 71, a driving screw 73, and a driving member 6. Among them, the driving assembly 71 includes a driving motor, the driving screw 73 is connected to the output shaft of the driving motor, the driving member 6 is sleeved on the driving screw 73, and the driving member 6 has an internal thread that mates with the external thread of the driving screw 73. When the driving screw 73 rotates under the drive of the driving motor, the driving member 6 moves linearly along the driving screw 73. The driving member 6 is specifically connected to the phase shifter of the antenna through a pull rod 74. When the driving member 6 moves linearly, it will drive the phase shifter to move, thereby realizing the adjustment of the downtilt angle of the antenna. Among them, the driving member 6 may specifically be a driving clamp.

[0043] In specific implementation, a switching assembly 72 is further provided between the driving assembly 71 and the driving screw 73. The driving screw 73 may be provided in multiple numbers, and the switching assembly 72 is used to switch between multiple driving screws 73 so that the driving motor drives a certain driving screw 73 to work.

[0044] In order to enable the operator to intuitively see the angle of the downtilt angle of the electrically adjustable antenna, this embodiment provides an electrically adjustable antenna downtilt angle display device and an antenna. The downtilt angle of the electrically adjustable antenna is displayed through this electrically adjustable antenna downtilt angle display device, and the production of this display device is relatively convenient. The following is a detailed description of it through specific embodiments:

[0045] Embodiment 1

[0046] Reference Figures 1 to 11 As shown, this embodiment provides an electrically adjustable antenna downtilt angle display device, including: a transmission rod 1, a rotating sleeve 2, and a scale disk 3.

[0047] The transmission rod 1 is connected to the driving member 6 for driving the phase shifter to move, so as to move linearly under the drive of the driving member 6. It can be understood that the driving member 6 is connected to the transmission rod 1 and the two are relatively fixed. When the driving member 6 moves linearly, it can drive the transmission rod 1 to move linearly.

[0048] Among them, a spiral protrusion 11 is provided on the outer side wall of the transmission rod 1, and the spiral protrusion 11 extends in the direction from one end of the transmission rod 1 to the other end of the transmission rod 1. It can be understood that the spiral protrusion 11 is arranged around the outer side wall of the transmission rod 1.

[0049] Exemplarily, the spiral protrusion 11 may be integrally formed with the transmission rod 1. For example, the transmission rod 1 is made of plastic material. When manufacturing the transmission rod 1, the spiral protrusion 11 is integrally injection molded on the outer side wall of the transmission rod 1. The specific protrusion height of the spiral protrusion 11 can be set according to actual needs, and this embodiment does not make specific limitations on this.

[0050] One end of the rotating sleeve 2 has an opening 21 through which the transmission rod 1 can extend into the inner cavity of the rotating sleeve 2. A groove 22 for cooperating with the spiral protrusion 11 is provided at the opening 21, so that when the transmission rod 1 moves linearly, the rotating sleeve 2 is driven to rotate. It can be understood that the transmission rod 1 can extend into the rotating sleeve 2 through the opening 21 of the rotating sleeve 2 and can move linearly in the rotating sleeve 2 under the drive of the driving member 6. When the transmission rod 1 extends into the rotating sleeve 2, a part of the spiral protrusion 11 on the outer side wall of the transmission rod 1 is located in the groove 22. Therefore, when the transmission rod 1 moves linearly, the rotating sleeve 2 will be driven by the transmission rod 1 to rotate.

[0051] The other end of the rotating sleeve 2 has an angle indicating needle 23, that is, the angle indicating needle 23 rotates synchronously with the rotating sleeve 2. The scale disk 3 is arranged at the other end of the rotating sleeve 2. The scale disk 3 has an angle mark 31. The downward inclination angle of the electrically adjustable antenna can be displayed through the relative position of the angle indicating needle 23 on the scale disk 3. That is to say, the angle indicating needle 23 can rotate relative to the scale disk 3 under the drive of the rotating sleeve 2, that is, when the rotating sleeve 2 rotates, the scale disk 3 does not rotate, and the angle indicating needle 23 rotates relative to the scale disk 3, and the position indicated by the angle indicating needle 23 on the scale disk 3 changes. When the rotating sleeve 2 stops rotating, the position indicated by the angle indicating needle 23 on the scale disk 3 at this time is the current downward inclination angle of the electrically adjustable antenna.

[0052] In specific implementation, the scale disk 3 can be made of a light-transmitting material so as to view the position of the angle indicating needle 23 through the scale disk 3. The angle mark 31 on the scale disk 3 specifically includes indicating scale lines and angle numbers. The indicating scale lines and angle numbers can be engraved on the scale disk 3 or can be pasted with scale labels.

[0053] One end and the other end of the above-mentioned rotating sleeve 2 are the opposite ends of the rotating sleeve 2. Referring to Figure 3 as shown, one end of the rotating sleeve 2 is the right end of the rotating sleeve 2, and the other end of the rotating sleeve 2 is the left end of the rotating sleeve 2.

[0054] The down-tilt angle display device of the electronic adjustable antenna provided in this embodiment sets spiral protrusions 11 on the outer sidewall of the transmission rod 1, so that the spiral protrusions 11 extend along the direction from one end of the transmission rod 1 to the other end of the transmission rod 1. At the opening 21 of the rotary sleeve 2 where the transmission rod 1 can extend into the rotary sleeve 2, a groove 22 for cooperating with the spiral protrusions 11 is provided. When the transmission rod 1 extends into the rotary sleeve 2, the spiral protrusions 11 are located in the grooves 22. In this way, when the transmission rod 1 moves linearly driven by the driving member 6, due to the cooperation between the spiral protrusions 11 on the transmission rod 1 and the grooves 22 at the opening 21 of the rotary sleeve 2, the transmission rod 1 will drive the rotary sleeve 2 to rotate, and the angle indicating needle 23 at the end of the rotary sleeve 2 rotates together with the rotary sleeve 2, that is, the angle indicating needle 23 rotates relative to the scale disk 3, and the relative position of the angle indicating needle 23 on the scale disk 3 shows the current down-tilt angle of the electronic adjustable antenna. Compared with the prior art, there is no need to set spiral grooves inside the rotary sleeve 2, and only by setting the groove 22 at the opening 21 of the rotary sleeve 2 and setting the spiral protrusions 11 on the outer sidewall of the transmission rod 1, the display of the down-tilt angle of the electronic adjustable antenna can be realized, thereby reducing the manufacturing process difficulty of the display device and improving the production efficiency.

[0055] Preferably, at least two spiral protrusions 11 can be set, and at least two spiral protrusions 11 are arranged at intervals on the outer sidewall of the transmission rod 1, and the spiral directions of all the spiral protrusions 11 are the same. Correspondingly, at least two grooves 22 are provided at the opening 21 of the rotary sleeve 2, and at least two grooves 22 are arranged at intervals along the circumference of the opening 21, and one spiral protrusion 11 corresponds to one groove 22.

[0056] When the transmission rod 1 extends into the rotary sleeve 2, each spiral protrusion 11 is located in the corresponding groove 22. When the transmission rod 1 moves linearly driven by the driving member 6, due to the cooperation between the spiral protrusion 11 and the groove 22, the transmission rod 1 will apply a force to the rotary sleeve 2, and the rotary sleeve 2 rotates under this force, thereby realizing the display of the down-tilt angle.

[0057] Among them, the spiral protrusion 11 can extend from one end of the transmission rod 1 to the other end of the transmission rod 1, so as to ensure the length of the spiral protrusion 11, so as to ensure the continuity of the cooperation between the spiral protrusion 11 and the groove 22 during the transmission process, and avoid the separation of the spiral protrusion 11 and the groove 22 due to the stroke of the transmission rod 1, resulting in the failure of the operation.

[0058] Refer to Figures 5 to 10As shown, in some embodiments, both the spiral protrusions 11 and the grooves 22 are provided in two. In other embodiments, the spiral protrusions 11 and the grooves 22 can also be provided in more than two. Compared with the prior art solution of only providing one stud on the push rod to cooperate with the spiral groove on the inner side wall of the spiral tube, the above setting in this embodiment enables a two-line drive or a multi-line drive to be formed between the drive rod 1 and the rotating sleeve 2, thereby improving the drive stability and drive efficiency.

[0059] To facilitate the mold opening of the rotating sleeve 2, all the grooves 22 at the opening 21 can be made such that their projections in the axial direction of the rotating sleeve 2 do not overlap each other.

[0060] Continue to refer to Figure 4 and Figure 5 As shown, a clearance through hole 24 is provided on the barrel wall of the rotating sleeve 2. The provision of the clearance through hole 24 can, on the one hand, facilitate the mold opening of the rotating sleeve 2. For example, when the rotating sleeve 2 is a plastic part formed by injection molding, such a setting makes the production of the rotating sleeve 2 more convenient; on the other hand, it can play a role in weight reduction, reducing the weight of the entire display device, saving production consumables, and thus saving production costs.

[0061] Specifically, the number of the clearance through holes 24 is at least two, and at least two clearance through holes 24 are arranged at intervals on the barrel wall of the rotating sleeve 2, and the clearance through holes 24 located on the opposite sides of the rotating sleeve 2 are staggered with each other in the axial direction of the rotating sleeve 2. Refer to Figure 4 As shown, that is, the clearance through hole 24 located on the upper side of the rotating sleeve 2 and the clearance through hole 24 located on the lower side of the rotating sleeve 2 are staggered with each other in the up and down direction, and such a setting further improves the convenience of manufacturing the rotating sleeve 2.

[0062] Refer to Figure 5 and Figure 6 As shown, a part of the edge of the opening 21 is recessed away from the direction of the opening 21 to form a notch 211. Such a setting makes the opening of the groove 22 more convenient, further reducing the manufacturing difficulty and improving the production efficiency.

[0063] In specific implementation, the groove 22 can be provided on the inner side wall of the part of the opening 21 except the notch 211, or the groove 22 can also be provided on the inner side of the notch 211. For example Figure 6 As shown, one of the grooves 22 is located on the inner side of the notch 211, and the other groove 22 is opposite to the notch 211.

[0064] In some embodiments, the end of the drive rod 1 far from the angle indicating needle 23 (i.e., Figure 8The right end of the middle transmission rod 1 has a connection section 12 extending along the axial direction of the transmission rod 1, and the driving member 6 is clamped on the connection section 12. In specific implementation, the connection section 12 can be integrally formed with the transmission rod 1. Of course, it can also be assembled together later. Among them, the driving member 6 can be a driving clamp, and the clamping head of the driving clamp is clamped on the connection section 12, so that the connection between the driving member 6 and the transmission rod 1 can be realized quickly and conveniently.

[0065] In order to improve the reliability of the connection between the transmission rod 1 and the driving member 6, and further improve the stability of the entire transmission process, in some embodiments, a limiting structure for preventing the driving member 6 from moving axially along the connection section 12 is provided on the connection section 12. Refer to Figure 3 and Figure 8 As shown, exemplarily, the limiting structure may specifically include a limiting flange 132 provided at the joint of the connection section 12 and the transmission rod 1 and a first snap ring 131 that can be clamped on the connection section 12. Among them, a slot 133 is provided on the connection section 12, and the first snap ring 131 is clamped in the slot 133. Further, a bolt is provided on the first snap ring 131, and a bolt hole for cooperating with the bolt is provided on the connection section 12. When the driving member 6 is clamped on the connection section 12, the first snap ring 131 is clamped on the connection section 12. At this time, the bolt enters the bolt hole, and the limiting flange 132 and the first snap ring 131 clamp the driving member 6 between them. Of course, in some other embodiments, two first snap rings can also be provided. When the driving member 6 is clamped on the connection section 12, the two first snap rings are respectively clamped at both ends of the driving member 6, so as to effectively prevent the driving member 6 from moving axially along the connection section 12 and improve the stability between the driving member 6 and the transmission rod 1.

[0066] Among them, the rotating sleeve 2 specifically includes: a hollow sleeve section 201 and an extension section 202. One end of the hollow sleeve section 201 has an opening 21, the extension section 202 is connected to the other end of the hollow sleeve section 201 and extends along the axial direction of the hollow sleeve section 201. The end of the extension section 202 far from the hollow sleeve section 201 has an angle indicating needle 23, and the scale disk 3 is arranged at the end of the extension section 202 far from the hollow sleeve section 201. The extension section 202 can be integrally formed with the hollow sleeve section 201, or can also be assembled together later. By setting the rotating sleeve 2 as the above two sections, only one section is set as a hollow sleeve shape to realize the cooperation with the transmission rod 1, and there is no need to set the entire rotating sleeve 2 as a hollow cylindrical structure, thus improving the production efficiency to a certain extent and reducing the production cost.

[0067] During specific installation, the electronic tilt angle display device of the antenna can be installed on the reflector 8 of the antenna through the support frame 4.

[0068] Among them, the support frame 4 is provided with a mounting structure for mounting the adjustable antenna downtilt display device. Specifically, the mounting structure can be set to at least two groups to mount at least two adjustable antenna downtilt display devices on the support frame 4. One group of mounting structures corresponds to one adjustable antenna downtilt display device, and one adjustable antenna downtilt display device corresponds to one phase shifter.

[0069] Referring to Figure 2 and Figure 3 As shown, the support frame 4 specifically includes: two support plates 41 that are spaced apart from each other and arranged oppositely. The mounting structure specifically includes first mounting holes 42 respectively arranged on each support plate 41. A first mounting hole 42 on one support plate 41 and a first mounting hole 42 on the other support plate 41 form a group of mounting structures. The two first mounting holes 42 of each group of mounting structures are coaxially arranged. The rotating sleeve 2 is inserted through the corresponding two first mounting holes 42, and the opening 21 is located outside the first mounting hole 42.

[0070] For example, three first mounting holes 42 are arranged on one support plate 41, and three first mounting holes 42 are arranged on the other support plate 41. The two support plates 41 together form three groups of mounting structures to mount three adjustable antenna downtilt display devices on the support frame 4.

[0071] Among them, a limiting structure for preventing the axial movement of the rotating sleeve 2 is further arranged outside the first mounting hole 42. Referring to Figure 3 As shown, the limiting structure specifically can include: a stop flange 252 and a second snap ring 251. After the rotating sleeve 2 is inserted through the first mounting hole 42 of the support frame 4, the stop flange 252 and the second snap ring 251 are blocked outside the two support plates 41. The stop flange 252 can be integrally formed with the rotating sleeve 2, for example. A card slot is arranged at the position of the rotating sleeve 2 corresponding to the installation of the second snap ring 251 to snap the second snap ring 251 into the card slot. Bolts can be arranged on the second snap ring 251, and bolt holes for cooperating with the bolts are arranged at the corresponding positions of the rotating sleeve 2.

[0072] In addition, a support 5 can be arranged. The support 5 supports one end of the extension section 202 far from the hollow sleeve section 201, and the support 5 is used to support the extension section 202. Among them, a second mounting hole 51 is arranged on the support 5, and the extension section 202 is inserted through the second mounting hole 51. The scale disk 3 is arranged on the side of the support 5 facing away from the rotating sleeve 2. By arranging the support 5, the stability of the entire display device can be further improved, thereby ensuring the display effect.

[0073] The support frame 4 and the support 5 can specifically be made of plastic, and this embodiment does not make specific limitations in this regard. The support frame 4 and the support 5 can be fixed to the reflector 8 by screws, or can be fixed to the reflector 8 by means of snap connection. In addition, the support frame 4 and the support 5 can be directly connected to the reflector 8, or a bottom plate can be provided on the reflector 8, and the support frame 4 and the support 5 are connected to the bottom plate.
