Problems solved by technology

The structure of the traditional electronic downtilt transmission device is relatively complex. When the number of beams is large, the internal space of the antenna will be larger, the size of the entire transmission device will be larger, and the cost will be greatly increased; at the same time, more precise control cannot be achieved

Embodiment Construction

[0041] 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.

[0042] It should be noted that when an element is referred to as being “fixed on”, “installed on”, “disposed on” or “installed on” another element, it may be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time; further, when an element is considered to be "fixed drive connected" to another element, both may It can be fixed in a detachable connection mode, and can...

Abstract

A bidirectional power output linkage device and an antenna downtilt angle control device, the bidirectional power output linkage device comprising: an input shaft (110); a first transmission mechanism (200), the first transmission mechanism (200) comprising a first inner gear ring (210), a first gear (220) which is coaxial with the first inner gear ring (210), a second gear (230) which forms an acting connection with the first gear (220), and a first planet carrier (240); a second transmission mechanism (300), the second transmission mechanism (300) comprising a first rotating member (310) which is fixedly in transmission connection with the first planet carrier (240), and a second rotating member (320) which forms an acting connection with the first rotating member (310); a third transmission mechanism (400), the third transmission mechanism (400) comprising a second planet carrier (410) which is mounted on the second rotating member (320), a third gear (420) which is mounted on the input shaft (110), and a fourth gear (430) which meshes with the third gear (420); a one-way control mechanism, which controls the rotation direction of the first rotating member (310) to be opposite to the rotation direction of the second rotating member (320).

Description

technical field [0001] The invention relates to the technical field of mobile communication equipment, in particular to a bidirectional power output linkage device and an antenna downtilt angle control device. 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] At present, there are two ways to adjust beam downtilt: mechanical downtilt and electronic downtilt, and electronic downtilt has obvious advantages, which is the current mainstream and future development trend. The structure of the traditional electroni...
