Description
Technical Field
The invention relates to the technical field of communication, in particular to a flat modular transmission device and a multi-frequency antenna.
Background
In a mobile communication network, the problem of coverage area and signal interference is often changed by adjusting the radiation angle of an antenna, so as to improve the operation quality of the communication network. The radiation angle of the antenna is usually achieved by driving a phase shifter in the antenna through an actuator to generate a phase change. A mobile communication antenna, such as a multi-frequency antenna, often has multiple phase shifters that are often adjusted differently and independently, asynchronously.
At present, the phase shifters of most antennas are driven by a motor and a set of transmission devices; for the multi-frequency antenna, a plurality of phase shifters are built in the multi-frequency antenna, and adjustment of the plurality of phase shifters is usually achieved by configuring a plurality of motors and transmission devices. On the one hand, however, the plurality of motors and the transmission device occupy the space inside the antenna, which increases the difficulty of the antenna structure layout and even increases the overall size of the antenna; on the other hand, this undoubtedly also increases the holistic cost of antenna, and motor and transmission depend on the phase shifter to place the installation simultaneously, and the installation is comparatively dispersed, and assembly efficiency is low.
Due to different frequency bands of the antennas or different phase shifter designs, the corresponding radiation angles of the antennas can be adjusted differently, which is reflected in the inconsistent phase shift distance of the phase shifters. For example, in a multi-frequency antenna having both low and high frequencies, the phase shift distance of the low frequency is sometimes more than one time of that of the high frequency; or on the high-frequency dual-frequency antenna of different frequency bands, the phase-shifting distances of the high-frequency dual-frequency antenna are still different. Therefore, the design of the transmission device is difficult due to the difference and uncertainty of the phase shift distance of the phase shifter.
The patent CN201611050463.4 discloses a modular transmission device, which provides a transmission device that uses revolution and rotation of gears to realize selection and control of different phase shifters, and simultaneously modularizes different functional parts of the transmission device, thereby increasing the ease of secondary development and the degree of freedom of redesign. However, the size of the transmission is large due to the limitation of design principle or the requirement of practical use, and particularly, there is little space for compression in the height dimension of the transmission. This is undoubtedly disadvantageous for the miniaturized design of the antenna.
The patent CN201610053873.8 discloses another structure way for selectively controlling different phase shifters by meshing a moving gear in a linear direction with gears at different positions, which also reduces the number of motors and the size of space. However, the described structure is not compact enough and lacks flexibility.

Two fixing clips 17 pass through the driving slotted hole 3.2 on one of the driving plates 3, and the driving retainer ring 18' is clamped in the fixing slotted hole 17.1 of the fixing clip 17, so that the fixing clip is fixed on the driving plate 3.
During installation, the positioning posts 17.3 of the two fixing clips 17 are preferentially inserted into the positioning holes 2.2 in the option plate 2. Under the guiding action of the positioning column 17.3, the end part of the transmission screw 15' is inserted into the coupling hole 12.1 of the coupler 12 in the position selection module 200, and simultaneously, the hook part 17.3 of the fixing clamp 17 elastically deforms outwards under the action of force to be clamped at the two sides of the position selection plate 2. At this time, the drive screw 15' and the corresponding drive rod 6 in the coupler 12 can be rotated synchronously.
The flat modular transmission device has compact integral structure, is mutually related and can be controlled in a linkage way. . On one hand, the existing scattered transmission device is integrated; on the other hand, the position selecting function, the driving function and the horizontal transmission function in the current multi-frequency transmission device are separated. Different modules are reasonably designed, so that the design can be flexibly adjusted, the overall structural mode is not influenced, and the design and development efficiency is improved.
The modular transmission of the present invention has six transmission modules 300, i.e., six transmission outputs, connected to different phase shifters. According to the phase shift distance difference of different phase shifters, the drive screw 15 and the pull rod 20 can be independently redesigned (such as lengthened or shortened), without affecting the structure of the device, and without affecting the installation and use of other drive screw modules adjacent to each other.
Furthermore, the number of the positioning holes 2.1 of the position selecting plate 2 can be increased or decreased appropriately to be four or eight, so that the output of an external output port is achieved. Thus, the use of different types of antennas can be met to the greatest extent by changing the design of few components. Meanwhile, most parts are universal, so that the utilization rate of the parts is improved, and the cost is reduced.
The flat modular transmission device is mainly characterized by flattening, separating a driving part from a positioning part, and independently forming a driving module and a positioning module, and simultaneously, independently forming a transmission module by a transmission screw part. Therefore, each module has respective functions, does not influence each other, can be independently installed, and effectively improves the production efficiency. One or more transmission modules can be directly replaced for different phase shifting distances without influencing the overall structure and installation. In addition, the position selection module can be developed for the second time according to the number of the actually used antenna frequency bands, so that the position selection module can be changed into an eight-frequency, five-frequency or four-frequency transmission device.
The flat modular transmission device has compact and flexible structure. By adopting the modular component design, different modular components can be independently assembled, the installation is convenient, the mass production is very facilitated, and the production efficiency is improved.
