[0002] The signal coverage area in mobile communications is achieved by installing a base station antenna at the base station and allowing the base station antenna's beam to cover this area. In order to adjust the beam radiation direction of the base station antenna, the signal phase of each unit inside the antenna can be changed by adjusting the phase shifter inside the base station antenna, thereby changing the direction of the beam. Therefore, the base station electrically adjustable antenna system plays a vital role in the mobile communication network. The phase shifter, as a key component to realize the antenna electrically adjustable function, is the focus of research on the electrically adjustable antenna. The radiation angle of the mobile communication antenna is achieved by driving the phase shifter inside the antenna through a transmission device, thereby adjusting the signal phase.

[0020] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0021] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present invention will be more comprehensive and complete, and the concept of the example embodiments will be fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solutions of the present invention may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0022] like Figure 1As shown, this patent discloses a large-scale array electrically adjustable antenna phase shifter transmission and control module integrated device, which mainly includes three parts: a driving component 1, a control module 2 and a frame-type transmission rod 3. The control module 2 is integrated in the driving component 1, and the two are integrated. The control module 2 is used to control the action of the driving component 1, and the driving component 1 is connected to the frame-type transmission rod 3. The driving component 1 is used to drive the frame-type transmission rod 3 to move. The frame-type transmission rod 3 is connected to the phase shifter pull rod 31. The phase shifter pull rod 31 is provided with a plurality of connecting parts 32 connected to the phase shifter, and the mechanism is connected to the phase shifter by toggling or pulling the connecting part 32. In order to facilitate the movement of the phase shifter, a fixing and guiding part can also be provided on the phase shifter pull rod 31, which is used to guide the movement of the phase shifter pull rod 31. The shape of the frame-type transmission rod 3 can be designed into a square, circular or other frame-type structure shape as needed. The use of this frame-type transmission rod 3 can simultaneously connect multiple phase shifters for shifting, ensuring that the phase shifters move synchronously.

[0023] As a specific implementation, the drive assembly 1 and the control module 2 can be integrated in a housing, and the integrated housing is set in the center of the frame-type transmission rod 3. At the same time, phase shifter pull rods 31 are set at the front and rear ends of the frame-type transmission rod 3. This increases the number of phase shifter connections and makes the structure of the entire phase shifter transmission device more compact, so that the phase shifter transmission mechanism has the advantages of small size, thin thickness and light weight.

[0024] like Figure 2 , 3 As shown, the drive assembly 1 includes a drive motor 11, and a transmission screw 12 is respectively provided on both sides of the drive motor 11. A transmission nut 13 is provided on the transmission screw 12. The drive motor 11 drives the transmission screw 12 to rotate through a transmission mechanism, and then drives the transmission nut 13 to move on the transmission screw 12. The transmission nut 13 is connected to the frame-type transmission rod 3, so that the rotation of the drive motor 11 can drive the frame-type transmission rod 3 to move. The control module 2 includes a RET control board, and the output end of the control module 2 is connected to the drive motor 11. The output torque and rotation direction of the drive motor are changed by the control module 2, and then the frame-type transmission rod 3 is controlled to move according to the required requirements.

[0025] Since the frame-type transmission rod 3 is to be connected with multiple phase shifters, in order to ensure the output torque, transmission screws 12 are respectively provided on both sides of the driving motor 11, and the driving motor 11 is connected with the motor driving gear 16. A transmission screw gear 19 is provided on the transmission screw 12, and the transmission screw gear 19 is connected with the motor driving gear 16 through the transmission gear 17, so that the driving motor 11 can drive the transmission screw 12 to rotate through the motor driving gear 16, the transmission gear 17, and the transmission screw gear 19. In order to further improve the output torque, the number of teeth of the motor driving gear 11 should be less than the number of teeth of the gear assembly 17, and the diameter of the motor driving gear 11 should be less than the diameter of the transmission gear 17, and the transmission ratio of the transmission gear to the transmission screw gear is 1:1. The use of this structure can increase the output torque of the driving motor 11 acting on the transmission screw 12, and ensure that the driving motor 11 can drive the frame-type transmission rod 3 and multiple phase shifters to easily perform the shifting operation.

[0026] For ease of installation, the drive assembly 1 can be arranged in the transmission base 10, and the drive screw 12 is installed in cooperation with the transmission base through the drive screw shoulder 18. The drive screw shoulder 18 can prevent the drive screw 12 from generating friction with the transmission base 10. The drive motor 11, the control module 2, the drive screw 12, the motor drive gear 16, the gear assembly 17, and the drive screw shoulder 18 are all installed in the transmission base 10, and a front baffle 15 and a rear baffle 14 are arranged on the front and rear sides of the transmission base 10 to ensure the operation of the drive assembly.

[0027] The large-scale array electrically adjustable antenna phase shifter transmission rod and control module integrated device integrates the control module and the driving component, and is arranged in the middle of the frame connecting rod. The frame connecting rod can be connected to multiple phase shifters through the driving component, so that the multiple phase shifters can be synchronously driven to move through the driving component; the driving component drives the transmission nut to move through the motor driving gear, the transmission gear, and the transmission screw; the transmission screw is installed in conjunction with the transmission base through the transmission screw shaft shoulder, so that the entire phase shifter structure can be more compact, and the phase shifter has the advantages of small size, thin thickness, light weight, small transmission error, etc.

[0028] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
