Description

Base station antenna bracket and base station antenna

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese patent application No. 2022115047310, filed on November 28, 2022, and entitled “Base Station Antenna Bracket and Base Station Antenna”, which is incorporated herein by reference in its entirety.

Technical Field

The present application relates to the field of antenna technology, and in particular to a base station antenna bracket and a base station antenna.

Background technique

With the development of mobile communication technology, multi-frequency and multi-port need to be integrated at the base station antenna end to improve network capacity.

At present, the most common solution for base station antenna mounting brackets is to use thicker steel plates, large-tonnage stamping equipment, combined with multiple sets of special stamping dies for forming, and hot-dip galvanizing after bending to form a surface protective layer. The main parts are composed of upper and lower corner arms with a U-shaped cross-section, and aluminum tubes are installed at the joints to support the locking parts to tighten and deform. This solution is costly and has a complex production process. The plate will cause material damage and thickness changes during the stamping and bending process, and zinc nodules or burrs will appear on the surface due to the hot-dip galvanizing process. The back of the antenna cover is an important area for rain and ultraviolet radiation. Under the influence of long-term harsh outdoor environment, the bolts will loosen. After aging of the material, the upper and lower corner arms will also loosen the connection nodes due to the weight of the antenna and the wind, resulting in changes in the antenna downtilt angle, functional failure, and even serious accidents such as antenna falling.

During packaging, the mounting bracket is packed separately into a box and placed at one end of the antenna packaging box. The upper and lower ends of the antenna are made of EPE or EPS foam or cardboard as buffers to prevent damage to the antenna caused by falling and impact during transportation. However, due to the increased weight of the multi-band high-gain antenna, this packaging method has a longer packaging size. On the one hand, the logistics cost is high, transportation is inconvenient, and the material waste is large. It does not meet environmental protection requirements, and the protection effect is not good. Once the moisture-proof and humidity-proof conditions of the outer carton change during transportation and storage, the packaging strength drops sharply, resulting in the inability to deliver the product normally.

During the installation process, the mounting bracket needs to be taken out of a separate packaging box, and then fixed to the antenna body with bolts. The antenna body is hoisted to the tower top or the rooftop mounting pole and then bolted. The process is cumbersome and inconvenient to operate. The whole process needs to be assisted by binding ropes, which is Safety hazards. When the length of the antenna fixing pole is limited, it will cause installation difficulties.

Rotating the second mounting plate 210 and/or the second clamp 220 can adjust the angular position between the antenna body 300 and the holding pole 400.

In the packaging and storage state, one end of the locking plate 140 is controlled to be disconnected, and the rotating plate 120, the first clamp 130, and the second clamp 220 are controlled to rotate toward the direction of the antenna body 300, so that the first clamp 130, the rotating plate 120, and the locking plate 140 are in a flattened state parallel to the outer wall of the antenna body 300, as shown in Figure 4, saving packaging space.

The base station antenna provided in this application has a small number of structural parts and a simple production process. It has high strength, high supporting stability, and a simple structure, and is suitable for large-scale manufacturing and automated production.

This application proposes a new type of base station antenna bracket based on a strip metal plate bending structure, with a small number of overall design parts, simplified production process, easy material acquisition and easy processing, effectively reducing The manufacturing cost is low; the pre-galvanizing process is free from post-processing surface treatment, and the cost is low, the weight is light, and the outdoor protection performance is good; the overall strength is improved through the bending design; the upper corner arm 121 and the lower corner arm 122 are both designed to be U-shaped by bending strip metal, and the angle can be adjusted by rotating before the base station antenna is installed. The locking plate 140 is made of bent strip metal plates to lock the adjusted angle under high wind load conditions.

When storing and transporting the antenna, the base station antenna bracket is spread flat to the outer wall of the antenna body 300 to save packaging volume and reduce packaging costs. When installing the base station antenna, the rotating plate 120 can be directly controlled to rotate and adjust to a suitable position for manual handling or hoisting, and it is convenient for installers to reduce the amount of construction. This design has simple parts to make, large bearing capacity, and can adapt to larger wind load intensity; it is light in weight, has fewer process steps, and a simple assembly process, which can effectively reduce manufacturing costs and improve installation efficiency. The base station antenna provided in this application can meet the application requirements of indoor and outdoor base station antennas, has a simple installation process, has high strength, and a simple structure, and is suitable for large-scale manufacturing and automated production.

In this application, the integral parts are formed by a bending process using metal plates or alloy plates, and are all made of standard galvanized steel strips, which have strong bearing capacity, simple structure, and simple bending process; they are pre-galvanized, and are free from post-processing surface treatment, with low cost, light weight, and good outdoor protection performance; after the upper bracket assembly 100 and the lower bracket assembly 200 are flattened, they can be turned to the middle of the antenna body 300 through the axis point for storage and transportation before the base station antenna is installed, which can effectively reduce the packaging size, avoid the bracket assembly being packaged separately, increase packaging safety, and save pallets and packaging materials. When going up to the station, because the upper and lower bracket assemblies are integrated with the antenna body 300, no secondary installation is required, which can effectively save workers' installation time and reduce outdoor work intensity.
