Embodiment Construction

[0028] 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.

[0029] 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-deta...

Abstract

The invention discloses an antenna, a transmission device and a switching mechanism. The switching mechanism comprises: a transmission piece; a position selecting unit which comprises a worm, a worm wheel and a driving gear, wherein the worm is rotatably arranged on the transmission part, the worm wheel is in transmission fit with the worm, and the driving gear synchronously rotates with the wormwheel; and a driving unit which is used for driving the transmission piece to reciprocate along a preset track. The switching mechanism can selectively drive the output shaft to rotate, and can adaptto the increase of the frequency band of the antenna without causing the complex transmission structure; according to the transmission device, the switching mechanism is adopted, power is provided foradjustment of the downward inclination angle, and a transmission system is simplified; and the antenna adopts the transmission device, a transmission system is simplified, the antenna can adapt to the increase of the frequency band of the antenna, and the reliability of the working performance of the multi-frequency antenna is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna, a transmission device 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 two categories: built-in and external, and built-in ...
