Problems solved by technology

[0004] However, the motor used to drive the phase shifter in the traditional transmission device still corresponds to the transmission mechanism of the phase shifter one by one, the number of motors has not been reduced, and the number of drive circuits in the control module has not been reduced as much as the number of motors
If the frequency band of the antenna continues to increase, the structure of the transmission system will be more complex and bulky, which will affect the reliability of the multi-frequency antenna

Embodiment Construction

[0033] 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.

[0034] 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, a switching mechanism. The switching mechanism comprises a screw rod, an output gear and a guide piece; the screw rod is rotatably arranged;an internal threaded hole in screw transmission fit with the screw rod is formed in the output gear; when the guide piece is fixed relative to the screw rod, the guide piece is in guide fit with the output gear; and when the guide piece rotates relative to the screw rod, the guide piece can drive the output gear to rotate, so that the output gear and the screw rod can synchronously rotate in the same direction. According to the switching mechanism, the number of power devices can be decreased; and two kinds of power are converted into at least two kinds of power so as to be output. According to the transmission device, the switching mechanism is adopted, so that the transmission structure of the transmission device can be simplified, and the reliability of a multi-frequency antenna can beimproved. With the transmission device adopted, the antenna has better reliability compared with the prior art.

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 ...
