Description

Technical Field

[0001] This utility model belongs to the field of mobile communication technology, and specifically relates to a base station antenna. Background Technology

[0002] With the rapid development of communication technology, the horizontal azimuth adjustment of base station antennas has a crucial impact on the coverage quality and signal transmission efficiency of communication networks. Currently, the horizontal azimuth adjustment of base station antennas mostly relies on external mounting brackets, adjusting the azimuth angle by controlling the overall pivot rotation of the base station antenna around an axis. However, this traditional structure has significant drawbacks in practical applications: Firstly, the traditional structure has poor adaptability to severe weather. In extreme weather conditions such as strong winds and heavy rain, the overall rotating structure of the antenna is susceptible to wind impact and rain erosion, leading to decreased adjustment accuracy or even mechanical failure. To ensure stability, high-strength, high-protection-level external brackets are required, significantly increasing material costs and installation difficulty. Secondly, the pivot rotation of base station antennas requires sufficient space for movement, resulting in a significant occupation of the limited installation space on communication towers, restricting the deployment of other communication equipment. This problem is particularly severe in densely populated urban areas or small communication tower scenarios, seriously affecting the expansion, upgrading, and optimized deployment of communication networks.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a base station antenna that solves the problems of poor adaptability to severe weather and large space occupation of the pivot structure of base station antennas.

[0026] Reference Figure 1 and Figure 2 As shown, one embodiment of this utility model provides a base station antenna, which includes an outer cover 1, a reflector 2, a connector 3, a bracket 4, and a telescopic component 5.

[0027] Specifically, the outer casing 1 has an internal cavity 11, and one of the cavity walls (i.e., one of the inner walls of the outer casing 1) forms an inner mounting surface 12. A reflector 2 is disposed within the cavity 11, facing the inner mounting surface 12 with a certain distance between them. A radiating element is provided on the side of the reflector 2 facing away from the inner mounting surface 12. The reflector 2 reflects the energy radiated backward and to the side by the radiating element to a specific area in front, thereby enhancing the gain of the base station antenna in the desired coverage direction and improving signal directivity and anti-interference capability. A connector 3 is located within the cavity 11 and is fixed to the inner mounting surface 12 to maintain its position. A bracket 4 is located within the cavity 11, fixedly connected to the side of the reflector 2 facing the inner mounting surface 12, and also pivotally connected to the connector 3, allowing the reflector 2 to pivot. The telescopic component 5 can be extended or retracted in a controlled manner. The two ends of the telescopic component 5 are pivotally connected to the connector 3 and the bracket 4, respectively. When the telescopic component 5 extends or retracts, it can drive the reflector 2 to pivot and adjust the azimuth angle of the base station antenna.

[0028] According to the above structural design, the connector 3, the bracket 4 and the telescopic component 5 form a pivot structure for adjusting the azimuth angle of the base station antenna. After the pivot structure is set inside the outer cover 1, on the one hand, it can prevent the external environment from contacting the pivot structure inside the outer cover 1, so that the pivot structure can adapt to the relatively harsh environment and improve the service life and stability of the pivot structure. On the other hand, it can also prevent the pivot structure from occupying the installation space of the communication tower and improve the space utilization of the communication tower.

[0029] In one embodiment, reference is made to Figure 3 and Figure 4As shown, the connector 3 includes a first extension plate 31 and a fixing plate 32. The fixing plate 32 is fixed to the inner mounting surface 12 by means of bolts or other methods, and is approximately in contact with the inner mounting surface 12. There are two first extension plates 31, which are bent towards the reflector 2 from opposite sides of the fixing plate 32 and extend towards the reflector 2. The two first extension plates 31 are arranged opposite each other, are approximately parallel to each other, and are also approximately perpendicular to the fixing plate 32.

[0030] The bracket 4 includes a second extension plate 41, a support plate 42, and a crossbeam plate 43. Two support plates 42 are provided and spaced apart on the reflector plate 2. The crossbeam plate 43 is located on the side of the two support plates 42 away from the reflector plate 2 and is generally parallel to the reflector plate 2. Two second extension plates 41 are provided, each bending from opposite sides of the crossbeam plate 43 towards the inner mounting surface 12 and extending towards the inner mounting surface 12. The two second extension plates 41 are positioned opposite each other, are generally parallel to each other, and are also generally perpendicular to the crossbeam plate 43.

[0031] Furthermore, in order to ensure a stable pivotal connection between the connector 3 and the bracket 4, and to maintain an appropriate distance between the reflector 2 and the inner mounting surface 12, the base station antenna also includes a first pivot shaft 6 that passes through the two first extension plates 31 and the two second extension plates 41, with the two first extension plates 31 and the two second extension plates 41 pivotally connected in a one-to-one correspondence.

[0032] Furthermore, to improve the installation efficiency of the connector 3 and the bracket 4, two second extension plates 41 are located between two first extension plates 31. During the installation process, the space between the two first extension plates 31 can form a structure similar to a positioning groove, so that the installer can quickly identify and position the bracket 4.

[0033] During the pivoting process of reflector 2, when reflector 2 interferes with the first extension plate 31 or the second extension plate 41 interferes with the fixed plate 32, it indicates that reflector 2 has pivoted to the limit position, that is, the azimuth angle of the base station antenna has reached the limit angle.

[0034] To increase the pivoting angle range of the reflector 2, in one embodiment, referring to Figure 4As shown, a first clearance surface 311 is formed on the side of the first extension plate 31 facing away from the inner mounting surface 12. In the direction away from the pivot point of the first extension plate 31, the distance between the first clearance surface 311 and the inner mounting surface 12 gradually decreases. Compared with the rectangular first extension plate 31, the provision of the first clearance surface 311 on the first extension plate 31 can increase the relative distance between the edge of the first extension plate 31 and the reflector 2, so that the reflector 2 can only interfere with the first extension plate 31 after pivoting to a larger angle, thereby increasing the pivoting angle range of the reflector 2.

[0035] Similarly, refer to Figure 4 As shown, a second clearance surface 411 is formed on the side of the second extension plate 41 facing away from the reflector 2. In the direction away from the pivot point of the second extension plate 41, the distance between the second clearance surface 411 and the reflector 2 gradually decreases. Compared with the rectangular second extension plate 41, the provision of the second clearance surface 411 on the second extension plate 41 can increase the relative distance between the edge of the second extension plate 41 and the fixed plate 32, so that the second extension plate 41 can interfere with the fixed plate 32 only after the reflector 2 is pivoted to a larger angle, thereby increasing the pivoting angle range of the reflector 2.

[0036] Furthermore, the second extension plate 41 is provided with two second clearance surfaces 411, which are symmetrically arranged along the first pivot axis 6.

[0037] Furthermore, referring to Figure 3 As shown, a second pivot shaft 7 is provided on one of the first extension plates 31 of the connector 3. The second pivot shaft 7 extends toward the first extension plate 31 away from the other first extension plate 31 and is pivotally connected to one end of the telescopic member 5. To prevent the telescopic member 5 from interfering with the outer cover 1, the position of the second pivot shaft 7 should be relatively far away from the outer cover 1. Therefore, in order to provide installation space for the second pivot shaft 7, only one first clearance surface 311 is provided on the first extension plate 31 of the connector 3. The second pivot shaft 7 and the first clearance surface 311 are respectively provided on both sides of the first pivot shaft 6.

[0038] It should be noted that the provision of a first clearance surface 311 on the first extension plate 31 in the above embodiments is one possible solution for practical application. For those skilled in the art, without departing from the technical principle of this application, the size of the first extension plate 31 or the size of the outer cover 1 can be appropriately increased, and two first clearance surfaces 311 can be provided on the first extension plate 31. These improvements should also be considered within the scope of protection of this application.

[0039] Furthermore, the two first extension plates 31 of the connector 3 and the two second extension plates 41 of the bracket 4 in the above embodiments are one possible solution for practical application. For those skilled in the art, without departing from the technical principle of this application, the number of the first extension plates 31 and the second extension plates 41 can also be increased or decreased, and these improvements should also be considered within the scope of protection of this application.

[0040] Furthermore, the first extension plate 31 and the fixing plate 32 of the connector 3 can be integrally formed by processes such as cutting and bending, or they can be spliced ​​together by processes such as welding, fusion, riveting, and bolting. Similarly, the bracket 4 can also be processed and formed using the above-mentioned forming processes.

[0041] In one embodiment, reference is made to Figure 1 As shown, the outer cover 1 also includes an outer mounting surface 13, which is disposed opposite to the inner mounting surface 12. An mounting plate 8 is provided on the outer mounting surface 13, and the mounting plate 8 is connected to the communication tower, thereby fixing the base station antenna on the communication tower.

[0042] Furthermore, the connector 3 and the mounting plate 8 are connected together by bolts, which pass through the fixing plate 32 of the connector 3, the corresponding shell wall of the outer cover 1 and the mounting plate 8 in sequence.

[0043] In one embodiment, reference is made to Figure 2 As shown, the inner mounting surface 12 of the outer cover 1 is provided with multiple connectors 3 arranged at intervals, and the reflector 2 is provided with multiple brackets 4 arranged at intervals. The multiple connectors 3 and the multiple brackets 4 are pivotally connected in a one-to-one correspondence. In addition, multiple telescopic members 5 are also provided, and the multiple telescopic members 5 are pivotally connected in a one-to-one correspondence with the multiple connectors 3, and are also pivotally connected to the reflector 2.

[0044] It should be noted that the telescopic component 5 in the above embodiments is an automated telescopic component, which can automatically extend and retract under the remote control of the operator or the control of the system program. The telescopic component 5 includes, but is not limited to, electrically controlled telescopic components, pneumatically controlled telescopic components, and hydraulically controlled telescopic components.

[0045] Preferably, the telescopic component 5 can be an electric push rod.
