Abstract
The utility model discloses an electronic tuning antenna drive mechanism, which is composed of an installing soleplate, a rotational bracket, a drive shaft, a drive nut, braking heads; the rotational bracket is arranged on the installing soleplate; the drive shaft is fixed on the rotational bracket to rotate; the drive shaft is a screw rod which is meshed with the drive nut; the drive nut is clung on the installing soleplate and is restricted by the installing soleplate, so as not to rotate around the drive shaft; when the drive shaft rotates, screw threads drive the drive nut to axially move, and two braking heads are respectively arranged at front and rear ends of the drive shaft; and the braking head can be stopped rotating when the drive nut moves to the braking head position, so as to restrict the drive shaft to rotate continuously, namely braking to the mechanism. Under the condition of using the low-price screw thread drive mechanism, the electronic tuning antenna drive mechanism greatly improves the defect that the mechanism is locked easily when adjusting the antenna at long-distance in prior art, and greatly enhances the project application reliability of adjusting the antenna at long-distance; the electronic tuning antenna drive mechanism has the advantages of reliable drive, simple structure, fewer components, low price and easy production.
Description
Technical field
The utility model relates to the antenna of mobile communication base station field, relates in particular to a kind of electrical tilt antenna transmission mechanism.
Background technology
Current electrical tilt antenna adopts the mode of screw thread transmission (or similar) to regulate lower decline angle more, when electrical tilt antenna is adjusted to minimum and maximum angle, must brake transmission mechanism, to guarantee to be no more than the adjustable range of antenna.In the practical application, increase the thrust (or pulling force) of screw axial often, make the screw thread locking reach the purpose of braking.In this case, just be difficult to after the screw thread locking unscrew, when the remote adjustment antenna, regulate failure easily, use to engineering and cause sizable trouble.
The utility model content
The utility model provides a kind of screw thread transmission electrical tilt antenna transmission mechanism of not locking.
For achieving the above object, the technical scheme that the utility model adopted is: the electrical tilt antenna transmission mechanism comprises the installation base plate, runing rest, power transmission shaft, transmission nut, stop head, runing rest is installed on to be installed on the base plate, power transmission shaft is fixed on the runing rest and rotates, power transmission shaft is a screw rod, transmission nut is engaged with, transmission nut is close to and base plate is installed the base plate restriction is installed and can not be rotated around power transmission shaft, when power transmission shaft rotates, screw thread promotes the transmission nut axial motion, a stop head is respectively installed at the head and the tail two ends of power transmission shaft, when transmission nut moves to the stop head position, stop the stop head rotation, also limited the continuation rotation of power transmission shaft thus and promptly mechanism has been braked.
In the such scheme, a scale is installed on the described transmission nut in order to show stroke or corresponding lower decline angle number of degrees value.
In the such scheme, described installation base plate is the reflecting plate of electrical tilt antenna.
The beneficial effects of the utility model are: the utility model is keeping adopting under the prerequisite of cheap thread transmission, the defective of the easy locking of mechanism when greatly having improved original technology medium-long range and regulating electrical tilt antenna, improved remote adjustment electrical tilt antenna engineering reliability of applying greatly, reliable transmission, simple in structure, building block is few, and is cheap, is easy to produce.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is described in further details:
Fig. 1, Fig. 2, Fig. 3 are all directions structural representation of the utility model embodiment;
Fig. 4 is the parts decomposition chart of the utility model embodiment;
Fig. 5 is the front schematic view of an application example of the utility model;
Fig. 6 is the schematic rear view of an application example of the utility model.
Embodiment
Figure 1 shows that the Facad structure schematic diagram of the utility model embodiment: power transmission shaft 1 is an external screw thread workpiece, and transmission nut 3 is an internal thread workpiece, and the two screws connection (as shown in Figure 2) by screw thread.As shown in Figure 3, the end of power transmission shaft 1 is installed a stop head 4 by screw, the other end carries similar stop head 4 shaped boss 10 as stop head, and power transmission shaft 1 is stuck in two runing rests 2 (as shown in Figure 4), and runing rest 2 is installed in to be installed on the base plate 5.
As shown in Figure 4, power transmission shaft 1 is stuck in two supports 2, when power transmission shaft 1 rotation, two runing rests 2 provide the stable rotation position for it, power transmission shaft 1 is provided with two stop head 4,10, these two stop head also can be rotated thereupon when power transmission shaft 1 rotation, transmission nut 3 is not followed rotation (referring to Fig. 2) because of stopping of base plate 5 is installed when power transmission shaft 1 rotation, can only be under the promotion of screw thread, promote transmission nut 3 axial motions, also respectively there is a boss both sides, transmission nut 3 front and back (as Fig. 1, Fig. 2, shown in Figure 3), carrying out along with axial motion, boss on the transmission nut 3 contacts with stop head boss on the power transmission shaft 1 the most at last and produces movement interference, and entire mechanism is stopped, and realizes the braking of mechanism, equally, when another stop head boss on power transmission shaft 1 of the axial motion of transmission nut 3, also will produce movement interference with it, and entire mechanism will be stopped.The moment screw thread of mechanism's braking is in relaxed state, and in whole motion process, the situation of screw thread locking does not appear in mechanism.
Distance on the power transmission shaft 1 between two stop head has determined the stroke of entire mechanism, under the situation of specific stroke and ridge distance, can calculate the number of turns that mechanism finishes the specific stroke power transmission shaft 1 required rotation of this section, promptly determined the stroke that mechanism finished under power transmission shaft 1 free position, by the corresponding relation of mechanism's stroke and electrical tilt antenna lower decline angle, we can regulate the lower decline angle that (rotation) power transmission shaft 1 realizes regulating electrical tilt antenna.
In Fig. 5, showed the example of the utility model in electrical tilt antenna is used with positive visual angle.The reflecting plate that base plate 5 is antenna is installed, when power transmission shaft 1 rotation, promoting transmission nut 3 (Fig. 5 is not shown) moves axially on installation base plate 5 (being reflecting plate), connecting plate 6 is installed on the transmission nut 3, connecting plate 6 is along with the motion drive phase shift block 7 of transmission nut 3 moves, so reach the purpose that changes antenna lower decline angle, driving interface 8 is used to connect long-range electrical tilt antenna driver (hereinafter to be referred as driver) among Fig. 5, and the actuating force of rotating drive shaft 1 provides (also manually rotating drive shaft 1 is regulated the lower decline angle of antenna) through this interface by driver.As shown in Figure 6, a scale 9 is installed on transmission nut 3, makes scale on the scale 9 and indicate corresponding angle value, when angle scale 9 moves with transmission nut 3, can demonstrate the corresponding lower decline angle number of degrees of antenna value.
