Abstract
The utility model discloses an electrically controlled antenna transmission mechanism, which is characterized by comprising a bottom plate (1), phase shifters (2), gears (3), racks (4) and a transmission rod (5), wherein the phase shifters (2) are fixed on the bottom plate (1) in two rows; each phase shifter (2) is provided with one gear (3); the racks (4) are arranged between the two rows of gears (3); the gears (3) are meshed with the racks (4); and the ends of the racks (4) are fixedly connected with the transmission rod (5). In the utility model, the phase shifters are meshed with one rack through the gears, and the racks drive the phase shifters to synchronously rotate. The utility model has the advantages of high rotation precision, flexible rotation, simple structure, high reliability, low cost and the like.
Description
Technical field
The utility model relates to a kind of communication electrical tilt antenna transmission mechanism.
Background technology
In mobile communication system, transmitting and receiving of spacing wireless signal all relies on portable antenna to realize.Electrical tilt antenna is meant the portable antenna that uses electronics to adjust tilt angled down.The principle of electrical tilt is by changing the phase place of conllinear array antenna oscillator, change the amplitude size of vertical component and horizontal component, changing synthetic component field intensity intensity, thereby the vertical directivity pattern of antenna is had a down dip.
Because the field intensity intensity of antenna all directions increases simultaneously and reduces, guarantee changing inclination angle aft antenna directional diagram variation not quite, the main lobe direction coverage distance is shortened, and the while makes whole directional pattern reduce area coverage again in the Serving cell sector but does not produce interference.Also there is not to realize quickly and easily the transmission mechanism of a plurality of phase shifter precise synchronization rotations of electrical tilt antenna in the prior art.
Summary of the invention
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of transmission mechanism that can realize that a plurality of phase shifter precise synchronization of electrical tilt antenna are rotated is provided.
Technical scheme: electrical tilt antenna transmission mechanism described in the utility model, comprise base plate, phase shifter, gear, tooth bar and drive link, a plurality of phase shifters divide two rows to be fixed on the described base plate, a gear is installed on each phase shifter, between the two toothrows wheel tooth bar is installed, described gear and the engagement of described tooth bar, fixedly connected with described drive link in the end of described tooth bar, the pulling drive link can drive tooth bar and move, the a plurality of gear rotations of rack drives realize a plurality of phase shifter precise synchronization rotations of electrical tilt antenna.
In order to make fixed effect relatively good, described phase shifter is fixed by fixed mount with corresponding gear.
In order to limit the moving direction of tooth bar, the conduct of described tooth bar is fixed by the tooth bar holder.The utility model gear and tooth bar all can adopt the plastics die sinking to make the working (machining) efficiency height.
The utility model compared with prior art, its beneficial effect is: a plurality of phase shifters of the utility model mesh by a plurality of gears and tooth bar, and a plurality of phase shifters of rack drives rotate synchronously, the rotation precision height rotates flexibly, and is simple in structure, the reliability height, low cost and other advantages.

Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solutions of the utility model are elaborated, but protection range of the present utility model is not limited to described embodiment.
As shown in the figure, a kind of electrical tilt antenna transmission mechanism comprises base plate 1, phase shifter 2, gear 3, tooth bar 4 and drive link 5, and a plurality of phase shifters 2 minutes two rows be fixed on the described base plate 1, each phase shifter 2 is provided with a gear 3, and fixed mount 6 is connected and fixed gear 3 and phase shifter 2; Between the two toothrows wheel 3 tooth bar 4 is installed, tooth bar holder 7 has limited the moving direction of tooth bar 4, and described tooth bar 4 is fixedlyed connected with described drive link 5.Pulling drive link 5 can drive tooth bar 4 and move, and tooth bar 4 drives a plurality of gear 3 rotations, thereby realizes a plurality of phase shifter precise synchronization rotations of electrical tilt antenna.
As mentioned above, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make various variations in the form and details to it.
