Embodiment Construction

[0039] In order to facilitate the understanding of the present invention, the antenna adjusting device will be described in a more comprehensive manner with reference to related drawings. A preferred embodiment of the antenna adjusting device is shown in the accompanying drawings. However, the antenna adjustment device can also be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the antenna adjusting device more thorough and comprehensive.

[0040] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. In contrast, when an element is referred to as being "direct...

Abstract

The invention discloses an antenna adjustment device. The antenna adjustment device comprises a transmission input assembly, a shift selection assembly, a transmission output assembly and a manual input assembly, wherein the transmission input assembly comprises a driving shaft, a plurality of first driving gears and a first driving assembly, the plurality of first driving gears are assembled on the driving shaft, the first driving assembly is used for driving the driving shaft to rotate, the shift selection assembly comprises a connection shaft, a rack and a second driving assembly, the racksleeves the connection shaft, the second driving assembly is used for driving the rack to slide, the transmission output assembly comprises an output driven wheel at one end and a lead screw at the other end, a nut is in threaded connection with an outer edge of the lead screw, the manual input assembly comprises an adjustment device, the adjustment device is engaged and connected with the outputdriven wheel of the transmission output assembly. With the manual input assembly of the antenna adjustment device, the reliability of continuous adjustment of a beam angle is ensured.

Description

Technical field [0001] The present invention relates to an adjustment device in a mobile communication antenna, in particular to an adjustment device for an antenna. Background technique [0002] In a wireless communication system, the base station antenna is the interface between the transceiver and the external propagation medium. In order to adjust the beam radiation direction of the base station antenna, the prior art usually uses a motor-driven transmission device to control the displacement of the phase shifter elements of each unit in the antenna, so as to realize the adjustment of the beam angle. [0003] Although the antenna azimuth adjustment device of the existing scheme can realize the adjustment of the beam angle, a single motor-driven transmission device has certain limitations and cannot guarantee the reliability of the continuous adjustment of the beam angle, and the transmission efficiency of the adjustment device is low , The cost is relatively high. [0004] Ther...
