Problems solved by technology

Due to the poor horizontal angle adjustment accuracy of this transmission form, complete self-locking cannot be realized (self-locking mechanism such as a brake is required to complete the self-locking function), and the transmission mechanism is prone to seizure, the overall strength of the antenna is poor, the accuracy of the electric adjustment is poor, and the cost higher defect

Embodiment Construction

[0028] see Figure 2-4 , the present invention provides a two-dimensional electrical adjustable antenna transmission structure, which includes a support 11 and a reflector 14 that can rotate relative to the support, a driving device, a transmission assembly fixed on the reflector 14, and a Arc driven rack 410, in the present embodiment, this driving device is motor 41, and this transmission assembly comprises the motor gear 42 that is connected on the drive shaft of this motor 41, the worm screw 414 that meshes with motor gear 42, by worm screw 414 drives and locks the worm wheel 47 and the drive gear 48 that rotates synchronously with the worm wheel 47 . The arc driven rack 410 meshes with the driving gear 48, and the driving gear 48 only has an axial degree of freedom to move circularly around the arc driven rack 410, while the arc driven rack 410 and the reflector 14 rotate The centers are coaxial, so the reflector can rotate around the center of rotation.

Abstract

The invention provides a two-dimensional electric tilt antenna transmission mechanism, comprising a support and a reflecting plate capable of rotating relative to the support, and further comprising a driving device, a transmission assembly fixed on the reflecting plate, and an arc-shaped driven rack fixed on the support, wherein the transmission assembly comprises a driving gear driven by the driving device; the arc-shaped driven rack is engaged with the driving gear; the driving gear only has the degree of axial freedom and circumferentially moves around the arc-shaped driven rack; and the arc-shaped driven rack is coaxial with the rotating center of the reflecting plate, so the reflecting plate can rotate around the rotating center. The transmission mechanism is simple in structure and convenient, and can effectively improve the precision of horizontal power transfer of an antenna, improve the overall structural strength of the antenna and reduce the production cost.

Description

【Technical field】 [0001] The invention relates to the field of communication, in particular to a two-dimensional electric adjustable antenna transmission mechanism. 【Background technique】 [0002] In the prior art, the transmission structure of the traditional two-dimensional electronically adjustable antenna is as follows: figure 1 As shown, the reflection plate 21 needs to rotate plus or minus 30 degrees relative to the support 22. Usually, the shaft 25 is assembled on the reflection plate 21, the transmission mechanism 23 is fixed on the support 22, and the transmission mechanism 23 is directly driven to rotate through the bearing 24. To realize the horizontal angle adjustment of the antenna. Due to the poor horizontal angle adjustment accuracy of this transmission form, complete self-locking cannot be realized (self-locking mechanism such as a brake is required to complete the self-locking function), and the transmission mechanism is prone to seizure, the overall streng...
