Description

Technical Field

[0001] The invention belongs to the technical field of mobile communications, and in particular relates to an antenna mounting bracket. Background Art

[0002] In the field of mobile communications, the selection and setting of base station antennas play a vital role in ensuring the network coverage quality, balanced traffic distribution, and optimized network service quality. According to key factors such as network coverage requirements, specific conditions of traffic distribution, and network service quality, the reasonable selection of base station antennas has become an important link in the construction of mobile communication networks. Among them, the setting of base station antennas not only needs to consider performance indicators such as antenna type and gain, but also needs to pay special attention to key parameters such as antenna downtilt angle and horizontal direction, which directly affect the network coverage effect and communication quality.

[0003] To achieve ideal network coverage, communication base station antennas usually optimize network layout by adjusting their pitch and horizontal angles. The pitch and horizontal angles can change the vertical coverage area of ​​the antenna beam, thereby achieving precise adjustment of signal coverage within different distance ranges; while the horizontal angle can change the horizontal coverage direction of the antenna beam to adapt to changes in different geographical locations and communication needs.

[0004] However, during the antenna setting process, the mounting bracket is an important component for supporting and adjusting the antenna, and its performance and adjustment method are also crucial. Traditional mounting brackets mainly change the pitch angle and horizontal angle of the antenna by manually adjusting the mechanical tilt angle, thereby achieving precise control of the antenna coverage range. Specifically, the pitch adjustment is usually achieved by fixing the lower end of the antenna so that the upper end of the antenna can be adjusted relatively away from or close to the antenna pole, thereby adjusting the beam coverage area; while the horizontal adjustment is achieved by rotating the antenna around the antenna pole to meet the coverage requirements in different directions. Although these two adjustment methods can meet most coverage requirements to a certain extent, they also have many limitations in practical applications.

[0005] In particular, most existing mounting brackets require manual adjustment, which is not only time-consuming and labor-intensive, but also inefficient. When the base station antenna is located in harsh environments such as the wild and mountainous areas, it requires a lot of manpower and material resources for maintenance. This manual adjustment method not only increases the operating cost burden of enterprises, but also makes it difficult to adapt to the rapid and flexible development needs of mobile communication networks.

The present invention can be operated in a safe environment through remote or automated adjustment, avoiding exposure of personnel to danger. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In an exemplary embodiment of the present invention, Figure 1 , the antenna mounting frame 100 is used to fix the antenna 400 on the pole 500. The antenna mounting frame 100 includes a first mounting frame 200 and a second mounting frame 300, the first mounting frame 200 and the second mounting frame 300 are sequentially arranged along the axial direction of the pole 500, the first mounting frame 200 is used to adjust the pitch angle of the antenna 400, and the second mounting frame 300 is used to adjust the horizontal rotation angle of the antenna 400. In this embodiment, the first mounting frame 200 is located above the second mounting frame 300 as an example to describe the present invention, but it should not be understood as limiting the present invention.

[0034] Combination Figure 1 and Figure 2 The first mounting frame 200 includes a first pole mount 210, a first antenna mount 220 and a pitch adjustment mechanism, wherein the first pole mount 210 is fixedly connected to the pole 500, the first antenna mount 220 is fixedly connected to the antenna 400, the pitch adjustment mechanism is pivotally connected to the first pole mount 210 and the first antenna mount 220 respectively, and the pitch adjustment mechanism can be opened and retracted in the pitch direction of the antenna 400, so that the antenna 400 can move in the pitch direction relative to the pole 500 to adjust the pitch angle of the antenna 400.

[0035] Specifically, the pitch adjustment mechanism includes a first rotating arm 230, a second rotating arm 240 and a pitch drive assembly, wherein the first rotating arm 230 is pivoted to the first holding rod seat 210, and the second rotating arm 240 is pivoted to the first antenna seat 220, and the first rotating arm 230 and the second rotating arm 240 are pivoted to each other via the pitch drive assembly, so that the first rotating arm 230 or the second rotating arm 240 can rotate relative to each other in the pitch direction to adjust the pitch angle of the antenna 400.

[0036] Combination Figure 3 The pitch drive assembly includes a first motor 250. An installation cavity 232 is enlarged on one end (the end is referred to as the second end 231) of the first rotating arm 230, and the first motor 250 is installed in the installation cavity 232. The output shaft of the first motor 250 is transmission-connected with one end (the end is referred to as the second end 241) of the second rotating arm 240, so that the first motor 250 drives the second rotating arm 240 to rotate in the pitch direction, so that the first rotating arm 230 and the second rotating arm 240 are opened or contracted in the pitch direction, thereby adjusting the pitch inclination angle of the antenna 400.

[0037] In this embodiment, the installation cavity 232 is provided with an opening, and the second end 241 of the second rotating arm 240 is expanded to form a mounting cover 242, and the mounting cover 242 covers the opening to close the installation cavity 232. In addition, the output shaft of the first motor 250 is in transmission connection with the mounting cover 242, and the first motor 250 drives the second rotating arm 240 to rotate through the mounting cover 242.

[0039] The first reducer 260 increases the torque of the output shaft of the first motor 250 by reducing speed, that is, the rotation speed is reduced, but the pitch drive assembly can generate a greater force to drive the second rotating arm 240 to rotate, especially when the antenna 400 is heavy, the second rotating arm 240 can be driven to rotate by the first reducer 260 to adjust the pitch angle of the antenna 400. In addition, the first reducer 260 can reduce the impact and load of the first motor 250 and extend the service life of the first motor 250.

[0040] The pitch drive assembly also includes an electromagnetic brake (the electromagnetic brake is referred to as the first electromagnetic brake 270), and the first electromagnetic brake 270 and the first reducer 260 are arranged on both sides of the first motor 250. The first electromagnetic brake 270 slows down or stops the movement of the first motor 250 by applying mechanical resistance (friction) by using electromagnetic force. By configuring the first electromagnetic brake 270, it can be ensured that the pitch drive assembly can stop operating quickly and safely when the first motor 250 accidentally loses control or needs to stop immediately, thereby avoiding possible accidents and damage. In addition, during the start and stop process of the first motor 250, a large impact and load will be generated. The first electromagnetic brake 270 can help the first motor 250 to start smoothly when starting and reduce the start impact; when stopping, it can reduce the load of the first motor 250 and extend the service life of the first motor 250 and the first reducer 260.

The pitch control unit is used to control the first motor 250, the first reducer 260, and the first electromagnetic brake 270 to work, so that the first motor 250, the first reducer 260, and the first electromagnetic brake 270 cooperate well, so as to drive the second rotating arm 240 to rotate well, thereby facilitating good adjustment of the pitch angle of the antenna 400. In this embodiment, it is recommended that the pitch control unit is a chip or a single-chip microcomputer, but it should not be understood as a limitation to the present invention.

[0042] In this embodiment, combined with Figure 4 , the pitch control unit is provided with a communication interface (the communication interface is referred to as the first communication interface 281), the first communication interface 281 is electrically connected to an external device through a cable, so that the external device outputs a first control signal to the pitch control unit, the pitch control unit parses the corresponding pitch adjustment angle data from the first control signal, and the pitch control unit controls the first motor 250, the first reducer 260 and the first electromagnetic brake 270 to work according to the pitch adjustment angle data, so as to adjust the pitch inclination angle of the antenna 400 accordingly. It can be understood that the first mounting bracket 200 can be remotely controlled by the external device, and the pitch inclination angle of the antenna 400 can be adjusted by the first mounting bracket 200, so as to reduce labor costs and improve the adjustment efficiency of the antenna. In this embodiment, it is recommended that the first communication interface 281 is an AI SG interface, but it should not be understood as a limitation to the present invention.

[0043] In one embodiment, the pitch control component also includes a communication unit (referred to as a first communication unit, not shown), and the pitch control unit is wirelessly connected to an external device via the first communication unit, so that the pitch control unit can wirelessly receive a first control signal output by the external device to adjust the pitch angle of the antenna 400.

[0047] During the process of the pitch driving assembly driving the second rotating arm 240 to rotate via the mounting cover 242, the mounting cover 242 will drive the pitch limiting portion 243 to rotate. Since the pitch limiting portion 243 is inserted into the pitch slide slot 291, the pitch limiting portion 243 will move along the extension path of the pitch slide slot 291, thereby limiting the rotational stroke of the pitch limiting portion 243 through the pitch slide slot 291, thereby controlling the rotational stroke of the second rotating arm 240, and further controlling the pitch stroke of the antenna 400, so that the pitch inclination angle of the antenna 400 is limited to avoid the pitch inclination angle being too large or too small.
