Referring to the attached drawing 1, the small distributed transmission device for the electrically tunable antenna is used for the electrically tunable antenna, is mainly applied to the field of 5G antennas with small space and irregular shapes, and drives a plurality of connected phase shifter loads to move linearly. The device comprises a controller 1, a fixing plate 6, a connecting mechanism 5, transmission mechanisms 4 and a guide mechanism, wherein the fixing plate 6 is used for providing mounting support for the structures, the controller 1 is fixed in the middle of the fixing plate 6, the two transmission mechanisms 4 are symmetrically arranged relative to the controller 1, and the controller 1 controls the two transmission mechanisms 4 to synchronously act; the two transmission mechanisms 4 are of the same specification, each transmission mechanism 4 is provided with a shell 4.7, a motor 4.1, a driving gear 4.2, a driven gear 4.3, a transmission screw 4.4, a transmission nut 4.5 and a guide shaft 4.6, the shell 4.7 is fixed on a fixing plate 6 through screws, the motor 4.1 is arranged on the central axis of the shell 4.7, the driving gear 4.2 is installed on the output shaft of the motor 4.1, the rotating axis of the driving gear 4.2 is the central axis of the shell 4.7, the two transmission screws 4.4 are symmetrically arranged relative to the rotating axis of the driving gear 4.2, the driven gear 4.3 is coaxially and fixedly installed on each transmission screw 4.4, the two driven gears 4.3 are respectively meshed with the driving gear 4.2 from one side of the driving gear 4.2, the transmission nut 4.5 is in threaded connection with each transmission screw 4.4, and the transmission nut 4.5 is fixedly connected with the connecting mechanism 5 through screws. Because the driven gear 4.3 and the driving gear 4.2 have the same module and tooth number, the two driven gears 4.3 can synchronously rotate in the same direction, and because the driven gear 4.3 and the transmission screw rod 4.4 implement rigid body constraint, the two transmission screw rods 4.4 can synchronously rotate in the same direction, and the corresponding transmission nut 4.5 can synchronously and linearly move in the same direction.
Considering that the transmission mechanism 4 can bear large torque, a guide shaft 4.6 parallel to the transmission screw 4.4 is arranged on one side of the transmission screw 4.4, and the transmission nut 4.5 is arranged on the guide shaft 4.6 in a sliding mode, so that the torsion of the transmission nut 4.5 caused by unilateral stress can be limited.
The connecting mechanism 5 is a flat plate hollow structure so as to reduce the self weight of the connecting mechanism 5, and two end parts of the connecting mechanism 5 are used for bearing loads in the moving direction of the connecting mechanism 5; the connecting mechanism 5 is provided with a plurality of sliding grooves 2, the fixing plate 6 is provided with a limiting column 3, and the limiting column 3 is inserted into the sliding grooves 2 to form a guide mechanism for guiding the connecting mechanism 5 in a linear motion manner.

In the above embodiment, the two transmission mechanisms 4 are symmetrically arranged, in practical use, one transmission mechanism 4 may be further arranged, and when one transmission mechanism 4 is arranged, the transmission mechanism 4 is located on the central axis of the connecting mechanism 5, that is, the rotation axes of the two transmission screws 4.4 are symmetrical with respect to the central axis of the connecting mechanism 5, so as to ensure that the output points (i.e., the transmission nuts 4.5) of the transmission mechanism 4 are distributed in a balanced manner, and correspond to a longer load arm. Of course, the number of the transmission mechanisms 4 may be an odd number, and at this time, one transmission mechanism 4 needs to be arranged on the central axis of the connection mechanism 5, and the other transmission mechanisms 4 are symmetrically arranged about the central axis of the connection mechanism 5; when the transmission mechanism 4 is an even number of more than two, the transmission mechanisms 4 are symmetrically distributed by taking the central axis of the connecting mechanism 5 as a symmetry axis, and the purpose is to make the output points (i.e. the transmission nuts 4.5) of the transmission mechanism 4 be distributed in a balanced manner.
During the use, coupling mechanism 5 can set up a monoblock, also can set up two, and when setting up two, drive mechanism also sets up to two, and every coupling mechanism 5 links to each other with a drive nut 4.5 of drive mechanism 4, because controller 1 drives two drive mechanism 4 synchronous motion, consequently drive nut 4.5 on two drive mechanism 4 can carry out synchronous, syntropy rectilinear motion, consequently two coupling mechanism 5 also can be synchronous, syntropy rectilinear motion.
