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

The invention relates to a bidirectional power output linkage device and an antenna downward inclination angle control device. The bidirectional power output linkage device comprises an input shaft, a first transmission mechanism, a second transmission mechanism, a third transmission mechanism and a one-way control mechanism. The first transmission mechanism comprises a first inner gear ring, a first gear coaxial with the first inner gear ring, a second gear in action connection with the first gear, and a first planet frame. The second transmission mechanism comprises a first rotary part in fixed and transmission connection with the first planet frame, and a second rotary part in action connection with the first rotary part. The third transmission mechanism comprises a second planet frame arranged on the second rotary part, a third gear installed on the input shaft, and a fourth gear engaged with the third gear. The one-way control mechanism is used for controlling the rotation direction of the first rotary part to be opposite to the rotation direction of the second rotary part. The bidirectional power output linkage device and the antenna downward inclination angle control device can realize independent and accurate control over the downward inclination angles of two or more beam antennas, the structure is compact, and the overall size is small.

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...
