[0002] This application claims priority to Chinese patent application No. 202311047639.0 filed on August 18, 2023, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] The present application relates to the technical field of communication equipment, and in particular to an antenna installation device and an antenna system. Background Art

[0004] With the rapid development of mobile internet technology, communication electronics are becoming increasingly popular, and they are becoming increasingly dependent on network communication quality, placing increasing demands on antenna equipment for signal coverage. In practical applications, after antenna equipment is installed, it is necessary to continuously adjust the antenna's orientation based on user feedback and measured data to adapt to actual signal transmission and reception conditions, thereby achieving network optimization.

[0005] Existing communication antennas are typically mounted on tall towers. Manually adjusting the antenna's orientation is time-consuming, labor-intensive, costly, and requires operators to perform tasks with low precision. Furthermore, operator safety is often a concern. Furthermore, in scenarios with high traffic tidal effects, such as stadiums, universities, and transportation hubs, the antenna's orientation needs to be frequently adjusted based on traffic flow. Manually adjusting the antenna's orientation in these situations cannot guarantee real-time performance.

[0015] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0016] In the subsequent description, suffixes such as "module," "component," or "unit" used to represent elements are used only to facilitate the description of the present application and have no specific meaning. Therefore, "module," "component," or "unit" may be used interchangeably.

[0017] Referring to FIG1 , this embodiment provides an antenna mounting device, which includes a bracket body 4 , a first connecting member 1 , a second connecting member 2 , a third connecting member 3 , and a first driving assembly 5 .

[0018] The bracket body 4 is connected to a pole for fixing the antenna. The bracket body 4 has a first end and a second end opposite to each other, and the first connecting member 1 is hinged to the first end of the bracket body 4.

[0019] It should be noted that the term “hinge” in this article refers to connecting two components using a rotation axis so as to connect the two components together and allow the two components to rotate relative to each other around the axis of the rotation axis.

[0020] The first drive assembly 5 is used to output linear power, and the power output end (first end) of the first drive assembly 5 is hinged to the first connecting member 1 to drive the first connecting member 1 to rotate around the first end of the bracket body 4. The first drive assembly 5 is hinged to the bracket body 4. Specifically, as shown in Figure 1, the end (second end) of the first drive assembly 5 is hinged to the main part of the bracket body 4, so that when the power output end of the first drive assembly 5 (following the first connecting member 1) makes a circular motion, the first drive assembly 5 as a whole can swing adaptively therewith to avoid limiting the movement path of the power output end, thereby avoiding limiting the rotation angle range of the first connecting member 1.

[0021] The two ends of the second connecting member 2 are respectively hinged to the antenna and the first connecting member 1, so that when it is driven by the first connecting member 1, it can drive the corresponding end of the antenna to move away from or closer to the holding pole, and then drive the antenna to flip (swing) around the second end of the bracket body 4, so as to adjust the pitch angle of the antenna, thereby making the antenna adapt to the actual signal reception and transmission conditions, improving the signal coverage range, and realizing network optimization.

[0022] One end of the third connector 3 is fixedly connected to the antenna, and the other end is hinged to the second end of the bracket body 4, so that the antenna can flip around the second end of the bracket body 4. In some embodiments, as shown in Figure 1, the third connector 3 and the antenna are connected by screws, for example.

[0023] The end of the second connector 2 connected to the first connector 1 can rotate around the first end of the bracket body 4 as the first connector 1 rotates, while the end of the second connector 2 connected to the antenna can rotate around the second end of the bracket body 4 as the antenna swings. It can be seen that the movement paths of the two ends of the second connector 2 are not consistent. Therefore, the second connector 2 is connected to the antenna and the first connector 1 in an articulated manner to avoid restricting the movement path of the second connector 2, thereby avoiding limiting the rotation angle range of the antenna during the transmission process to the antenna. In some embodiments, as shown in Figure 5, the second connector 2 is hinged to the antenna, for example, via an adapter 21.

[0024] Referring to Figures 1 and 2 , in the transmission structure formed by the first drive assembly 5, the first connector 1, the second connector 2, and the antenna, the first connector 1 can be considered a lever, the first end of the bracket body 4 can be considered a fulcrum, the hinged connection between the power output end of the first drive assembly 5 and the first connector 1 can be considered the power application point, the hinged connection between the second connector 2 and the first connector 1 can be considered the resistance application point, and the distance between the power application point and the fulcrum is the power arm, while the distance between the resistance application point and the fulcrum is the resistance arm. In this embodiment, the distance between the end of the second connector 2 hinged to the first connector 1 and the first end of the bracket body 4 is less than the distance between the power output end of the first drive assembly 5 and the first end of the bracket body 4. In other words, the length of the power arm connected to the first drive assembly 5 is greater than the length of the resistance arm connected to the second connector 2. According to the lever principle: "power × power arm = resistance × resistance arm", this transmission structure can achieve that the first drive assembly 5 outputs a relatively small driving force but can move a relatively heavy antenna, thereby reducing the driving force requirement of the first drive assembly 5. In other words, it can increase the weight of the antenna that the antenna mounting device can bear. In contrast, existing technical solutions typically drive the movement of the antenna by directly adding a power module to the base station antenna mounting device, and the power module is generally a labor-intensive structure. As the integration of base station equipment becomes increasingly higher, the weight of the antenna is also increasing. This results in the driving force of the existing antenna mounting device often being insufficient to adjust the orientation angle of the antenna device, resulting in the inability to adjust the antenna orientation angle in real time according to actual signal transmission and reception requirements, which in turn leads to problems such as signal transmission and reception delays in application scenarios. It can be seen that because this embodiment can increase the weight that the antenna mounting device can bear, the antenna mounting device proposed in this embodiment is more suitable for the load-bearing requirements of today's base station equipment, and can flexibly adjust the orientation angle of heavier antennas, thereby reducing the occurrence of signal transmission and reception delays in application scenarios.

[0025] Moreover, as mentioned above, since the length of the power arm is greater than the length of the resistance arm, the stroke of the power action point will also be greater than the stroke of the resistance action point, that is, the stroke of the power output end of the first drive component 5 will be greater than the stroke of the end of the second connecting member 2 hinged to the first connecting member 1, and thus will also be greater than the stroke of the antenna end. In other words, the antenna mounting device provided in this example can improve the angle adjustment accuracy of the antenna swing, thereby improving the adjustment accuracy of the antenna pitch angle, and thus improving the adjustment accuracy of the signal coverage range.

[0026] In some embodiments, as shown in Figure 1, the two ends of the first connecting member 1 are hinged to the power output end of the first driving component 5 and the first end of the bracket body 4, respectively, and the end of the second connecting member 2 is hinged to the main part of the first connecting member 1; that is, the power application point and the resistance application point are both set on the same side of the fulcrum.

[0027] In other embodiments, as shown in Figure 3, the two ends of the first connecting member 1 are respectively hinged to the power output end of the first drive assembly 5 and the end of the second connecting member 2, and the first end of the bracket body 4 is hinged to the main part of the first connecting member 1; that is, the power application point and the resistance application point are respectively arranged on both sides of the fulcrum.

[0028] In some embodiments, as shown in Figure 1, the antenna mounting device further includes a pole connection assembly 6 and a second drive assembly 7. The pole connection assembly 6 is detachably fixed to the pole and articulated with the bracket body 4, enabling the bracket body 4 to rotate about a first axis to adjust the antenna's azimuth, thereby further adapting the antenna to actual signal transmission and reception conditions, improving signal coverage, and achieving network optimization. The power output end of the second drive assembly 7 is connected to the bracket body 4 to drive the bracket body 4 to rotate. In some embodiments, the first axis is parallel to the pole axis, so that the antenna's circumferential rotation path encircles the pole and prevents interference between the antenna and the pole during rotation about the first axis.

[0029] Furthermore, in some embodiments, as shown in FIG4 , the pole connection assembly 6 includes two mounting blocks 61, two pairs of mounting rods 62, and two baffles 63. The two mounting blocks 61 are hingedly connected to the first and second ends of the bracket body 4 using a first pin 64 and a second pin 65, respectively. The first pin 64 and the second pin 65 both extend along the first axis, allowing the bracket body 4 to rotate about the first axis.

[0030] Mounting rods 62 are arranged in pairs on the side of the mounting block 61 that is close to the pole, with each pair of mounting rods 62 clamped to either side of the pole. Two baffles 63 are located on the side of the pole away from the mounting block 61 and slidably engage with the corresponding pair of mounting rods 62. When the baffles 63 slide to abut the pole surface, the pole connection assembly 6 is clamped to the pole, generating friction between them and the pole, thereby securing the antenna mounting device and antenna to the pole. Furthermore, when the baffles 63 slide to a position that releases contact with the pole surface, the pole connection assembly 6 is disconnected from the pole, allowing the antenna mounting device and antenna to be removed from the pole.

[0031] In some specific embodiments, the surfaces of the two pairs of mounting rods 62 are processed with threads, and as shown in FIG4 , the two baffles 63 are also provided in pairs with nuts on the side away from the holding pole that cooperate with the threads on the surface of the mounting rods 62 , so that the baffles 63 can be slid and pressed against the surface of the holding pole using the nuts.

[0032] In some embodiments, the second drive assembly 7 includes a second push rod motor 71 and a second push rod 72. The first push rod motor 51 is connected to the outer periphery of the holding rod and is used to drive the second push rod 72 to extend and retract; the end of the second push rod 72 is hinged to the bracket body 4 through the third pin 73, so as to be able to push and pull the bracket body 4 to rotate around the first axis. In some embodiments, as shown in Figure 1, the end (or bottom) of the second push rod motor 71 can be hinged and fixed to the holding rod so that when the end of the second push rod 72 makes a circular motion, the second drive assembly 7 as a whole can swing adaptively therewith to avoid limiting the movement path of the end of the second push rod 72, thereby avoiding limiting the rotation angle range of the bracket body 4.

[0033] In some embodiments, the antenna mounting device further includes a controller 8, which is electrically connected to the second push rod motor 71 and is used to control the second push rod motor 71 to drive the second push rod 72 to extend and retract, thereby automatically controlling the rotation of the bracket body 4 and further automatically adjusting the azimuth angle of the antenna.

[0034] In some embodiments, the first drive assembly 5 includes a first push rod motor 51 and a first push rod 52; the first push rod motor 51 is hinged to the bracket body 4 and is used to drive the first push rod 52 to extend and retract; the end (distal end) of the first push rod 52 is hinged to the first connector 1 to drive the first connector 1 to rotate about the first end of the bracket body 4. This end of the first push rod 52 is the power output end of the first drive assembly 5. Moreover, the controller 8 is also electrically connected to the first push rod motor 51 and is used to control the first push rod motor 51 to drive the first push rod 52 to extend and retract, thereby automatically controlling the antenna flip and then automatically adjusting the antenna's pitch angle.

[0035] In some embodiments, the controller 8 can control and adjust the azimuth and pitch angles of the antenna based on user feedback data and signal measured data to achieve optimal signal coverage; or, the controller 8 can communicate with the ground control center to receive control signals, thereby indirectly controlling the first push rod motor 51 and the second push rod motor 71.

[0036] In some embodiments, the antenna mounting device further includes a controller bracket 9, which is connected and fixed to the third connecting member 3 and is used to carry the controller 8. As shown in FIG1 , the third connecting member 3 is connected to the second end of the bracket body 4, and the first push rod motor 51 and the second push rod motor 71 are both arranged near the second end. Therefore, by fixing the controller bracket 9 to the third connecting member 3, the controller 8 can be placed close to the first push rod motor 51 and the second push rod motor 71, thereby shortening the wiring between the controller 8 and the first push rod motor 51 and the second push rod motor 71, thereby minimizing interference of the wiring with the operation of other components.

[0037] In some embodiments, the distance between the second end of the bracket body 4 and the pole axis is greater than the distance between the first end of the bracket body 4 and the pole axis, that is, the first end of the bracket body 4 is closer to the pole. Taking the antenna mounting device shown in Figure 1 as an example, the pole extends vertically, and the first end of the bracket body 4 is arranged higher than the second end. When the first push rod 52 retracts to its shortest position, the first connector 1 rotates to a position parallel to the bracket body 4, and the second connector 2 and the antenna also rotate to a position parallel to the bracket body 4, so that the antenna surface can face diagonally upward. As the first push rod 52 extends, the first connector 1 rotates and moves away from the bracket body 4, driving the upper end of the antenna away from the pole, so that the antenna surface can face horizontally and diagonally downward.

[0038] In some embodiments, at least one mounting hole 41 is formed in the bracket body 4. The mounting hole 41 corresponds to the position of the first push rod motor 51, allowing the first push rod motor 51 to pass through when the first push rod motor 51 rotates, thereby preventing the first push rod motor 51 from interfering with the bracket body 4.

[0039] As another technical solution, this embodiment also provides an antenna system, as shown in Figure 1, which includes an antenna, a pole, and the antenna mounting device described above. The antenna is used to transmit and receive signals, and the antenna mounting device is used to connect the antenna to the pole.

[0040] The antenna mounting device and antenna system proposed in this application utilize a hinged first connector 1 and a second connector 2 to connect the bracket body 4 to the antenna. The first connector 1 is used as a lever, and the first end of the bracket body 4 is used as a fulcrum. Thus, by pushing the first connector 1 to rotate, the second connector 2 can be pushed away from or toward the pole, thereby driving the antenna to flip (or swing) around the second end of the bracket body 4, thereby adjusting the antenna's pitch angle. Furthermore, the distance from the end of the second connector 2 hinged to the first connector 1 to the first end of the bracket body 4 is less than the distance from the power output end of the first drive assembly 5 to the first end of the bracket body 4, that is, the length of the power arm connected to the first drive assembly 5 is greater than the length of the resistance arm connected to the second connector 2. Based on the principle of leverage, such a structure enables the first drive assembly 5 to output a smaller driving force to push a heavier antenna, thereby reducing the demand for driving force. In other words, it can increase the weight of the antenna that the antenna mounting device can bear. In addition, since the stroke of the power output end of the first drive component 5 is greater than the stroke of the end of the second connecting member 2 hinged to the first connecting member 1, and thus also greater than the stroke of the antenna end, the angle adjustment accuracy of the antenna swing or pitch can be improved.

[0041] The preferred embodiments of the present application are described above with reference to the accompanying drawings, but the scope of the rights of the present application is not limited thereby. In some embodiments, the antenna mounting device may adopt an orientation that is upside down from the orientation shown in the accompanying drawings (i.e., the first and second connectors are at the bottom and the third connector is at the top), or the pole and bracket body in the antenna system may be arranged at a certain angle to the vertical direction. It is understood that any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope and essence of the present application shall be within the scope of the rights of the present application.
