Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0030]It should be noted that when an element is referred to as being "fixed on", "disposed on", "fixed on" or "installed on" another element, it can be directly on the other element or there can also be an intervening element . When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. Furthermore, when one element is considered to be "transmission-connected" to another element, the two can be fixed in a detachable connection or in a non-detac...

Abstract

The invention discloses a base station antenna, an electric downward inclined transmission device and a switching mechanism. The switching mechanism comprises a mounting assembly, wherein the mountingassembly comprises a first mounting plate and a second mounting plate arranged at opposite intervals. A first transmission assembly includes a telescopic member and a drive member for driving the telescopic member to reciprocate in a preset linear direction; and a second transmission assembly including a first transmission shaft, a second transmission shaft for driving the input gear to rotate, and an abutment member. The switching mechanism can realize the meshing switching between the input gear and at least two output gears. The transmission device of the electric downward inclination adopts the switching mechanism, so that the electric downward inclination of at least two phase shifters can be adjusted by two motors, the mechanism of the transmission system is greatly simplified, andthe cost is saved; The base station antenna adopts the transmission device of the electric downward inclination angle, which greatly simplifies the mechanism of the transmission system and saves the cost.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a base station antenna, a transmission device for an electric downtilt angle, and a switching mechanism. Background technique [0002] With the increasing number of mobile communication terminal users, the demand for network capacity of sites in the mobile cellular network is increasing. At the same time, it is required to minimize the interference between different sites or even between different sectors of the same site, that is, to realize the network Maximize capacity and minimize interference. To achieve this purpose, it is usually achieved by adjusting the downtilt angle of the antenna beam on the station. [0003] Among the two methods of adjusting beam downtilt, mechanical downtilt and electronic downtilt, electronic downtilt has obvious advantages and is the current mainstream and future development trend. Electric downtilt control is mainly divided into t...
