Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to a power feeding network system, an antenna, a base station, and a communication system. Background Art

[0002] With the development of mobile communications, the usage rate of mobile terminals is getting higher and higher, and the network coverage of mobile cellular networks is the key to mobile communications. Since the key device in a mobile cellular network is an antenna, in order to meet different network coverages, the antenna usually adopts an electric tuning system to adjust the signal coverage range. Currently, in order to change the coverage range of the antenna and optimize the signal coverage area of the antenna, it is generally achieved by changing the signal radiation tilt angle of the antenna. The adjustment of the signal radiation tilt angle of the antenna is usually to change the phase distribution of the antenna array through a phase shifter, so as to adjust the radiation pattern of the antenna, thereby achieving the purpose of adjusting the signal coverage range.

[0003] The phase shifter can drive the movement of its medium through a power mechanism to change the relative position between the medium and the strip line, thereby changing the dielectric constant on the signal transmission path in the phase shifter. In this way, when the signal of the antenna passes through the phase shifter, it can cause a certain phase delay or advance in the transmission of the signal of the antenna, thereby realizing the directional adjustment of the radiation direction of the signal of the antenna. However, currently, the size and weight of the power mechanism used for the phase shifter are relatively large, and it cannot meet the development requirements of antenna miniaturization and lightweight. Summary of the Invention

[0004] This application provides a power feeding network system, an antenna, a base station, and a communication system to achieve the miniaturization and lightweight design of the antenna.

[0005] In a first aspect, this application provides a power feeding network system, which includes a power feeding network and a power mechanism. Among them, the power feeding network includes a first housing, a fixing member, and a sliding member. The fixing member and the sliding member are accommodated in the first housing. The fixing member is connected to the first housing, and the fixing member is provided with a functional circuit. The power mechanism includes a driving device, and the driving device is used to drive the sliding member to slide relative to the fixing member to change the electrical parameters of the functional circuit. In the power feeding network system provided in this application, by adopting an integrated design for the power feeding network and the power mechanism, it is beneficial to improve the integration degree of the power feeding network system, and thus beneficial to realize the miniaturization design of the power feeding network system.

[0006] In a possible implementation manner of this application, the fixing member, the sliding member, and the driving device are integrally designed. This is beneficial to improve the integration degree of the power feeding network system, thereby meeting the design requirements of miniaturization and lightweight of the power feeding network system.

[0007] In a possible implementation of the present application, the power mechanism further includes a second housing, the driving device is installed in the second housing, and the second housing is fixedly connected to the first housing. This facilitates the connection between the power mechanism and the feeding network and can reduce the external leakage of magnetic signals that may be generated in the power mechanism, which is beneficial to reducing the interference of the power mechanism on the antenna radiation signal.

[0008] In a possible implementation of the present application, the driving device and the sliding member can be directly connected, that is to say, the driving device and the sliding member can be in direct contact and transmission connection, so that the acting force output by the driving device can be directly transmitted to the sliding member, which is beneficial to improving the transmission efficiency of the acting force between the driving device and the sliding member and is beneficial to reducing the volume of the feeding network system.

[0009] In a possible implementation of the present application, a first slot is provided on the end surface of the first housing facing the second housing, and a second slot is provided on the end surface of the second housing facing the first housing. The first slot and the second slot are arranged opposite to each other. In this way, the driving device can be connected to the sliding member through the first slot and the second slot, which is beneficial to improving the convenience of connecting the driving device and the sliding member.

[0010] In a possible implementation of the present application, a part of the sliding member is located in the second housing, and the driving device is connected to the part of the sliding member located in the second housing. This can make the feeding network and the power mechanism more compactly designed, which is beneficial to reducing the overall volume of the feeding network system.

[0011] In the present application, the driving device can adopt various possible setting forms, and the following gives an exemplary description thereof.

[0012] In a possible implementation of the present application, the driving device includes a resonant component, and the resonant component includes a metal elastic body and a piezoelectric material layer. Among them, the piezoelectric material layer is disposed on at least one surface of the metal elastic body. The metal elastic body includes a driving foot, and the driving foot presses against the sliding member and can be used to drive the sliding member to slide. In the present application, the driving device uses the piezoelectric driving method to convert the microscopic movement of the metal elastic body into the macroscopic movement of the sliding member. Since the volume of the driving device is small, it is beneficial to reduce the size of the power mechanism, thereby realizing the miniaturized design of the feeding network system.

[0013] In this implementation, the resonant component also includes a power supply module, which is used to apply a voltage to the piezoelectric material layer so that the piezoelectric material layer drives the metal elastomer to deform according to a set rule under the action of the corresponding voltage. In the present application, the voltage applied to the piezoelectric material layer can be adjusted to adjust the motion law of the metal elastomer, thereby adjusting the motion trajectory of the sliding member driven by the metal elastomer. It can be understood that the drive device designed based on the piezoelectric drive principle provided by the present application can facilitate the adjustment of the motion trajectory of the sliding member, which is conducive to improving the flexibility of the integrated design of the power mechanism and the feeding network.

[0014] In addition, the driving device of the above implementation also includes a positive preload component, which is used to press the driving foot of the metal elastic body toward the sliding member under the action of elastic force, thereby effectively improving the contact friction between the driving foot and the sliding member, so as to improve the reliability of the metal elastic body in driving the sliding member.

[0015] Based on the design of the above-mentioned driving device, the power mechanism may further include a follower, the follower is located between the driving foot and the sliding member, and the driving foot of the metal elastic body presses against the follower. Wherein, the follower is connected to the sliding member, and the driving foot can be used to drive the follower to drive the sliding member to slide. In this implementation, by using the follower as a transition piece between the driving device and the sliding member, the flexibility of the connection method between the driving device and the sliding member can be improved.

[0016] There are many ways to connect the follower and the sliding member. For example, the end of the follower facing the sliding member includes a gear, and the end of the sliding member facing the follower includes a rack surface, so that the transmission connection between the follower and the sliding member can be achieved by meshing the gear surface of the gear with the rack surface. In addition, in this implementation, by providing a rack surface meshing with the gear on the sliding member, it is beneficial to improve the compactness of the feed network system, which is beneficial to reduce the volume of the feed network system.

[0017] Alternatively, the end of the follower facing the slider includes a protrusion, and the end of the slider facing the follower includes a groove, so that the follower and the slider are connected by inserting the protrusion into the groove. This can help reduce the distance between the follower and the slider, thereby facilitating the miniaturization of the feed network system.

[0018] In another possible implementation of the present application, the driving device includes a micro motor. Additionally, the power mechanism further includes a gear, and the end of the sliding member facing the gear includes a rack surface. The gear surface of the gear meshes with the rack surface, and the micro motor is used to drive the gear to rotate, so as to enable the gear to drive the sliding member to move. In this implementation, by providing a rack surface on the sliding member that meshes with the gear, it is beneficial to improve the compactness of the feed network system, and thus beneficial to reducing the volume of the feed network system.

[0019] In another possible implementation of the present application, the driving device includes a micro motor, the power mechanism further includes a worm gear, and the sliding member includes a worm. Then, the worm gear meshes with the worm, and the micro motor is used to drive the worm gear to rotate, so as to drive the worm to move through the worm gear, thereby realizing the movement of the driving device driving the sliding member relative to the fixed member. In this implementation, by arranging the worm on the sliding member, it is beneficial to improve the compactness of the feed network system, and thus beneficial to reducing the volume of the feed network system.

[0020] In another possible implementation of the present application, the driving device includes a micro motor, the power mechanism further includes a worm, and the end of the sliding member facing the worm includes a rack surface. The worm meshes with the rack surface, and the micro motor is used to drive the worm to rotate, so as to drive the sliding member to move through the worm. Such a design is beneficial to improving the integration degree of the feed network system, and thus beneficial to realizing the miniaturized design of the feed network system.

[0021] In another possible implementation of the present application, the driving device includes a micro motor, the power mechanism includes a gear, and the sliding member includes a gear surface. The gear surface of the gear meshes with the gear surface of the sliding member, and the micro motor is used to drive the gear to rotate, so as to enable the gear to drive the sliding member to move. In this implementation, by providing a gear surface on the sliding member that meshes with the gear, it is beneficial to improve the compactness of the feed network system, and thus beneficial to reducing the volume of the feed network system.

[0022] In another possible implementation of the present application, the driving device includes a linear motor, and the output end of the linear motor is connected to the sliding member. Since the structure of this driving device is relatively simple, it is beneficial to reducing the volume of the power mechanism, and thus beneficial to reducing the overall size of the feed network system.

[0023] In the present application, there can be various specific setting methods for the feed network. Exemplarily, in one possible implementation, the fixed member includes a metal strip line, a functional circuit is provided on the metal strip line, and another functional circuit is provided on the sliding member. Among them, the other functional circuit of the sliding member is coupled and electrically connected to the functional circuit of the metal strip line. When the feed network adopts the above design method, during the process of the sliding member sliding relative to the fixed member, the electrical parameters of the functional circuit of the fixed member can be changed by changing the way of coupled electrical connection between the two functional circuits.

[0024] In this implementation manner, the feeding network can be a reconfigurable network, and the functional circuit of the metal strip line and the other functional circuit of the slider can be selected according to the function to be realized by the feeding network. Exemplarily, the functional circuit of the metal strip line can include at least one of a power divider, a bridge, a filter, and a transmission line. The other functional circuit of the slider can include at least one of a power divider, a bridge, a filter, and a transmission line.

[0025] In another possible implementation manner of the present application, the fixing member includes a metal strip line, the metal strip line is provided with a functional circuit, the slider includes an insulating medium, and the insulating medium covers a part of the metal strip line. With this design of the feeding network, during the process of the slider sliding relative to the fixing member, the part of the metal strip line covered by the insulating medium changes, thereby causing the dielectric constant of the environment where the entire metal strip line is located to change, so as to change the electrical performance of the metal strip line.

[0026] In this implementation manner, the feeding network can be a phase shifter. Then, when the slider slides relative to the fixing member to change the dielectric constant of the environment where the metal strip line is located, the electrical length of the antenna signal transmitted through the metal strip line can be changed, so as to realize the adjustment of the phase of the antenna signal by the phase shifter.

[0027] In another possible implementation manner of the present application, the fixing member includes a metal strip line, the metal strip line is provided with a functional circuit, the slider includes a metal sliding piece, and the metal sliding piece is coupled and electrically connected to the metal strip line. With the above design of the feeding network, during the process of the slider sliding relative to the fixing member, the way of the coupled electrical connection between the two can be changed, thereby changing the electrical parameters of the functional circuit of the fixing member.

[0028] In this implementation manner, the feeding network can also be a phase shifter. Then, when the slider slides relative to the fixing member to change the electrical parameters of the functional circuit of the metal strip line, the electrical length of the antenna signal transmitted through the metal strip line is changed, so as to realize the adjustment of the phase of the antenna signal by the phase shifter.

[0029] In the present application, the specific arrangement manner of the feeding network and the power mechanism is not limited. Exemplarily, in a possible implementation manner, the first housing is a hollow structure, then the first housing includes a hollow area, and the power mechanism can be installed in the hollow area. This can make the arrangement of the power mechanism and the feeding network more compact, thereby facilitating the realization of the miniaturized design of the feeding network system.

[0030] Second aspect, the present application also provides an antenna, which includes a control system and at least two feed network systems as described in the first aspect. Among them, the control system is used to control the driving device of each feed network system to drive the sliding member to slide relative to the fixed member. In the antenna provided by the present application, since the feed network and the power mechanism of the feed network system adopt an integrated design method, the feed network system can be installed and arranged in the antenna as a whole, which is beneficial to reducing the space occupied by the feed network system in the antenna, and is beneficial to improving the flexibility of the layout of the feed network system in the antenna, so as to reduce the complexity of the antenna design, and thus is beneficial to meeting the design requirements of miniaturization and light weight of the antenna.

[0031] Third aspect, the present application also provides a base station, which includes a radio frequency processing unit, a baseband processing unit, and the antenna of the second aspect. The baseband processing unit is connected to the antenna through the radio frequency processing unit. Since the antenna provided by the present application has a small volume, a larger number of antennas can be arranged in the base station, which is beneficial to increasing the types of signals that the base station can radiate, and thus expanding the applicable range of the base station.

[0032] Fourth aspect, the present application also provides a communication system, which includes a terminal and the base station of the third aspect. Among them, the terminal is communicatively connected to the base station. The communication system provided by the present application has better communication performance.

However, the exemplary embodiments can be implemented in various forms and should not be construed as being limited to the embodiments described herein. The same reference numerals in the drawings denote the same or similar structures, and thus the repeated description thereof will be omitted. The words expressing positions and directions described in the embodiments of the present application are all illustrative with reference to the drawings, but can be changed according to needs, and all the changes are included in the protection scope of the present application. The drawings in the embodiments of the present application are only used to illustrate the relative positional relationship, and do not represent the actual proportion.

[0078] It should be noted that specific details are set forth in the following description to facilitate an understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present application. Therefore, the present application is not limited by the specific implementation manners disclosed below.

[0079] To facilitate an understanding of the feeding network system, antenna and base station provided by the present application, the application scenarios thereof will be introduced first below. Figure 1 An exemplary schematic diagram of a communication system architecture applicable to the embodiments of the present application is shown, such as Figure 1As shown, the communication system architecture may include a base station 1000 and a terminal 2000. Wireless communication can be achieved between the base station 1000 and the terminal 2000. The base station 1000 can also be referred to as an access network device or an access node. It can be located in a base station subsystem (BBS), a UMTS terrestrial radio access network (UTRAN), or an evolved universal terrestrial radio access (E-UTRAN) for cell coverage of signals to enable communication between terminal devices and the wireless network. Specifically, the base station 1000 can be a base transceiver station (BTS) in a global system for mobile communication (GSM) or a code division multiple access (CDMA) system, a Node B (NB) in a wideband code division multiple access (WCDMA) system, an evolved Node B (eNB or eNodeB) in a long term evolution (LTE) system, a transmission reception point (TRP), a next generation Node B (gNB) in a 5G mobile communication system, a next generation base station in a sixth generation (6G) mobile communication system, an access network device or a module of an access network device in an open RAN (ORAN) system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The base station can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. described below. Among them, in the ORAN system, the CU can also be called an O-CU, the DU can also be called an open (O)-DU, the CU-CP can also be called an O-CU-CP, the CU-UP can also be called an O-CUP-UP, and the RU can also be called an O-RU.The base station 1000 of the present application can be a macro base station, a micro base station or an indoor station, a relay node or a donor node, or can also be a radio controller in a cloud radio access network (CRAN) scenario. Or the base station 1000 can also be a server, a vehicle-mounted device, a wearable device, and a g node (gNodeB or gNB) in a new radio (NR) system, an access network device in a future evolved network, etc. For example, the base station in vehicle to everything (V2X) technology can be a road side unit (RSU).

The base station 1000 can communicate with the terminal 2000 or can also communicate with the terminal 2000 through a relay station. The terminal 2000 can communicate with multiple base stations 1000 in different access technologies.

[0080] The base station 1000 is equipped with an antenna 100 to realize the transmission of signals in space. Figure 2 As shown Figure 1 FIG. shows a schematic diagram of an application scenario of the antenna 100 equipped on the base station 1000. Figure 2 Structures such as a support frame 200 and an antenna 100 are shown. The antenna 100 includes an antenna cover 10. The antenna 100 is fixed to the support frame 200 such as a pole or a tower through the antenna cover 10, so as to facilitate the reception or transmission of signals by the antenna 100. The antenna cover 10 has good electromagnetic wave penetration characteristics in terms of electrical performance and can withstand the influence of the external harsh environment in terms of mechanical performance, so as to play a role in protecting the antenna system from the external environment.

[0081] The base station 1000 may further include a radio frequency processing unit 300 and a baseband processing unit 400. The antenna 100 is connected to the radio frequency processing unit 300 through an antenna connector 20 located outside the antenna cover 10. The baseband processing unit 400 can be connected to the antenna 100 through the radio frequency processing unit 300. In some embodiments, the radio frequency processing unit 300 can also be referred to as a remote radio unit (RRU), and the baseband processing unit 400 can also be referred to as a baseband unit (BBU).

[0082] The support frame 200 is fixed to the ground and at a certain height from the ground. The antenna 100 is fixed to the support frame 200, which can meet the radiation distance requirement of the antenna 100. The antenna 100 is specifically detachably fixed to the support frame 200 through an adjustment bracket 600, so as to facilitate the reception or transmission of signals by the antenna 100. Along the direction perpendicular to the height of the support frame 200, the orientation of the antenna 100 can be adjusted through the adjustment bracket 600.

[0083] In a possible embodiment, as Figure 2 shown, the radio frequency processing unit 300 may be integrally provided with the antenna 100, and the baseband processing unit 400 is located at the far end of the antenna 100. At this time, the radio frequency processing unit 300 and the antenna 100 can be collectively referred to as an active antenna unit (AAU). It should be noted that Figure 2 this is only an example of the positional relationship between the radio frequency processing unit 300 and the antenna 100. In some other embodiments, the radio frequency processing unit 300 and the baseband processing unit 400 may also be located at the far end of the antenna 100 at the same time. The radio frequency processing unit 300 and the baseband processing unit 400 can be connected by a connecting wire 500.

[0084] A grounding device 700 is provided between the baseband processing unit 400 and the connecting wire 500. The grounding device 700 generally includes a grounding electrode buried underground. A seal can be provided at the connection between the antenna 100 and the connecting wire 500, and a seal can also be provided at the connection between the grounding device 700 and the connecting wire 500. The seal may specifically include at least one of an insulating sealing tape and a polyvinyl chloride (PVC) insulating tape. Of course, the seal may also be other structures and is not limited to the form of a tape.

[0085] Furthermore, Figure 3 is a schematic structural diagram of the antenna 100 provided by the embodiment of the present application. As Figure 3 shown, the antenna 100 may include a radiation unit 30 and a reflector 40. Among them, the radiation unit 30 may also be referred to as an antenna element, an element, etc. The radiation unit 30 is a unit that constitutes the basic structure of the antenna array, and it can effectively radiate or receive antenna signals. The frequencies of different radiation units 30 may be the same or different. The reflector 40 may also be referred to as a bottom plate, an antenna panel, or a metal reflecting surface, etc. The reflector 40 can reflect and concentrate the received signals at the receiving point. The radiation unit 30 is usually placed on one side of the reflector 40, which can not only greatly enhance the signal receiving or transmitting ability, but also block and shield the interference signals from the back of the reflector 40. Among them, in the present application, the back of the reflector 40 refers to the side of the reflector 40 opposite to the side where the radiation unit 30 is provided.

[0086] In the antenna 100, a feeding network system is provided between the radiation unit 30 and the antenna connector 20. The feeding network system can provide specific power and phase for the radiation unit 30. The feeding network system usually may include an adjusting unit 50 and a feeding network, as Figure 3As shown, the feeding network includes a phase shifter 60. The adjusting unit 50 is used to achieve different radiation beam directions, and the phase shifter 60 is used to change the maximum direction of signal radiation. By correspondingly adjusting the corresponding radiation units 30 through the phase shifter 60, the electrical down-tilt angle of the signals radiated by each radiation unit 30 can be changed, thereby changing the radiation directions of each radiation unit 30 to meet the signal coverage requirements.

[0087] As Figure 3 shown, a functional module 70 can also be provided between the phase shifter 60 and the antenna connector 20. The functional module 70 can expand the performance of the antenna 100. Exemplarily, the functional module 70 can include one or a combination of at least two of a combiner, a power divider, a filter, and a microwave circuit. The combiner or the power divider can be used in the forward or reverse direction to divide one signal into multiple signals or combine multiple signals into one signal. The filter can be used to filter out interference signals. In some cases, the phase shifter 60 also has the function of a power divider or a combiner. In this case, the power divider or the combiner can be omitted in the feeding network system. Different devices included in the feeding network system can be connected through transmission lines and connectors. It should be noted that the power divider or the combiner can be located inside or outside the radome 10, and the connection relationships between the various different components mentioned above are not unique, Figure 3 and only one possible positional relationship and connection method of the various components are exemplified.

[0088] which can continue to refer to Figure 3 , the adjusting unit 50 can specifically include a driving mechanism 5a and a calibration network 5b. The driving mechanism 5a can drive the phase shifter 60 to change the directions of different radiation beams of the antenna 100. The calibration network 5b sends a calibration signal to the driving mechanism 5a to control the operation of the driving mechanism 5a.

[0089] Among them, taking the phase shifter 60 as a dielectric phase shifter as an example, the principle that the driving mechanism 5a drives the phase shifter 60 to change the directions of different radiation beams of the antenna 100 is as follows: The driving mechanism 5a drives the insulating medium of the phase shifter 60 to move relative to the metal strip line, thereby changing the relative position between the insulating medium and the metal strip line. Since the environment where the metal strip line of the phase shifter 60 is located has a certain dielectric constant, when the relative position between the insulating medium and the metal strip line changes, the dielectric constant of the environment where the metal strip line is located changes. And the metal strip line can be electrically connected to the radiation unit 30 of the antenna 100. Then, by changing the dielectric constant of the environment where the metal strip line is located, the phase of the antenna signal transmitted through the metal strip line can be adjusted, thereby realizing the directional adjustment of the radiation direction of the signal of the antenna 100.

[0090] In current antennas, the phase shifter and the power mechanism are usually two independently designed parts, that is to say, they are designed separately and then installed and arranged in the antenna respectively. In addition, in current antennas, the power mechanism of the feed network system generally adopts a design method of a rotary motor, a rack and pinion, and a driving rod. Among them, the driving rod is connected to the insulating medium of the rack and pinion and the phase shifter. In this way, the rotary motor can drive the gear to rotate and drive the rack to move linearly, and then the driving rod can drive the insulating medium to move linearly relative to the metal wire under the drive of the rack. Since the rotary motor itself has a relatively large volume, and the rotary motion of the rotary motor needs to be transmitted to the driving rod through the rack and pinion before being transmitted to the insulating medium, there are many intermediate transmission mechanisms between the rotary motor and the insulating medium. This makes the volume and weight of the power mechanism relatively large, and its cost is relatively high, so that the feed network system occupies a relatively large space in the antenna, and it cannot meet the development requirements of the current antenna for miniaturization and lightweight.

[0091] In view of this, the feed network system provided in this application integrates the power mechanism and the feed network, so that the power mechanism and the feed network can be installed and arranged in the antenna as a whole, which is beneficial to reducing the space occupied by the feed network system in the antenna, and thus is beneficial to meeting the miniaturization design requirements of the antenna. To facilitate the understanding of the technical solution of this application, the feed network system provided in this application will be specifically described below in conjunction with the drawings and specific embodiments.

[0092] In this application, integrated design means that multiple structures are connected directly or indirectly to move or install as a whole, which is beneficial to improving the compactness of the multiple structures adopting the integrated design, and can achieve the effect of structural simplification through the sharing of some structures, thus being beneficial to reducing the space occupied by the multiple structures.

[0093] Refer to Figure 4 , Figure 4 FIG.

[0094] In addition, in Figure 4In the shown power supply network system, the power mechanism 5a includes a second housing 501, and the first housing 601 is fixedly connected to the second housing 501 so that the power supply network 6 and the power mechanism 5a are integrated into a whole. This is conducive to realizing the miniaturized design of the power supply network system, thereby improving the layout flexibility of the power supply network system.

[0095] It is worth mentioning that the present application does not limit the specific connection method between the first housing 601 and the second housing 501. Exemplarily, the first housing 601 and the second housing 501 can be detachably connected by a threaded connection, which is conducive to improving the maintenance convenience of the power supply network 6 and the power mechanism 5a. In addition, the first housing 601 and the second housing 501 can also be fixedly connected by welding, riveting or bonding, etc. to improve the connection reliability between the two. In addition, the first housing 601 and the second housing 501 can be directly connected or indirectly connected through an intermediate transfer structure, as long as the power mechanism 5a and the power supply network 6 can be connected and integrated into a whole. In some possible embodiments, the first housing 601 and the second housing 501 can also be an integrally formed structure, which can make the structure of the power supply network system more compact, so as to be conducive to reducing the volume of the power supply network system.

[0096] Refer to Figure 5 , Figure 5 For Figure 4 the exploded view of the power supply network system shown in. In the embodiment of the present application, the first housing 601 includes a first surface 6011, and this first surface 6011 is used to connect with the second housing 501, so the first surface 6011 is the end face of the first housing 601 facing the second housing 501. The first surface 6011 is a hollowed-out surface to facilitate the connection between the components in the power supply network 6 and the components in the power mechanism 5a. In addition, the other surfaces of the first housing 601 can be all closed surfaces, so that the first housing 601 can play a role in protecting other components in the power supply network 6.

[0097] In addition, in Figure 5In the shown feed network system, the second housing 501 includes a second surface 5011, and the second surface 5011 is the end face of the second housing 501 facing the first housing 601. The second surface 5011 can be a hollowed-out surface to facilitate the connection between the components in the power mechanism 5a and the components in the feed network 6. Additionally, the other surfaces of the second housing 501 can all be closed surfaces, so that the second housing 501 can protect other components in the power mechanism 5a and reduce the external leakage of the magnetic signals that may be generated in the power mechanism 5a, which is beneficial to reducing the interference of the power mechanism 5a on the antenna radiation signal. Or, in some other possible embodiments of the present application, for example, when the presence or absence of magnetic components in the feed network 6 does not interfere with the antenna radiation signal, all the surfaces of the second housing 501 can be hollowed-out surfaces. At this time, the second housing 501 can be understood as a frame structure, which is beneficial to reducing the weight of the power mechanism 5a, thereby reducing the overall weight of the feed network system and improving the convenience of transportation and installation of the feed network system.

[0098] In the embodiments of the present application, to facilitate the connection between the components in the feed network 6 and the components in the power mechanism 5a, in addition to setting the first surface 6011 of the first housing 601 and the second surface 5011 of the second housing 501 as hollowed-out surfaces, it is also possible to only set a first slot ( Figure 5 not shown in the figure) on the first surface 6011 of the first housing 601, and the other parts of the first surface 6011 except the first slot can be closed surfaces. Additionally, a second slot ( Figure 5 not shown in the figure) is opened on the second surface 5011 of the second housing 501, and the other parts of the second surface 5011 except the second slot are closed surfaces. Among them, the first slot and the second slot are arranged oppositely, so that the components in the feed network 6 and the components in the power mechanism 5a can be connected through the first slot and the second slot. It can be understood that the shapes and sizes of the first slot and the second slot can be specifically set according to the design requirements of the components connected between the feed network 6 and the power mechanism 5a, and they are not limited in the present application.

[0099] It can be understood that, Figure 4 FIG. shows a schematic diagram of an arrangement manner of the feed network 6 and the power mechanism 5a. Among them, the first surface 6011 is a relatively large end face of the first housing 601 of the feed network 6. When the feed network system is specifically applied, the arrangement manner of the feed network 6 and the power mechanism 5a can also be adaptively adjusted according to the layout space of the specific application scenario or the specific structures of the feed network 6 and the power mechanism 5a. Exemplarily, in Figure 6 the shown feed network system, the power mechanism 5a is connected to the relatively small end face of the first housing 601 of the feed network 6. Another example is in Figure 7In the shown feed network system, the power mechanism 5a is arranged on another end face of the feed network 6 with a larger area. Another example is Figure 8 In the shown feed network system, the first housing 601 of the feed network 6 is a hollow structure. The first housing 601 includes a hollow area 6012. Then, the power mechanism 5a can be installed in the hollow area 6012 of the first housing 601, which can make the overall structure formed by assembling the feed network 6 and the power mechanism 5a more compact. The above are only several exemplary descriptions of the arrangement modes of the feed network 6 and the power mechanism 5a. On this basis, the arrangement modes of the two can be adaptively deformed, and they will not be introduced one by one here, but they should all be understood to fall within the protection scope of this application.

[0100] Referring to Figure 9 , Figure 9 is Figure 4 the A-A cross-sectional view of the feed network system shown in

[0101] Continue to refer to Figure 9 , the power mechanism 5a further includes a driving device 502, and the driving device 502 can be installed on the second housing 501. In this application, the fixing member 602, the sliding member 603 and the driving device 502 are integrally designed, which is beneficial to reducing the volume and weight of the feed network system.

[0102] The driving device 502 can be used to drive the sliding member 603 to slide relative to the fixing member 602. It can be understood that according to the design requirements of specific application scenarios, the driving device 502 can be specifically set so that the driving device 502 can drive the sliding member 603 to slide relative to the fixing member 602. Among them, the sliding track of the sliding member 603 sliding relative to the fixing member 602 can be a straight line or a set curve, and it will not be specifically limited in this application.

[0103] In addition, as can be understood from the above introduction of the first housing 601 of the feeding network 6 and the second housing 501 of the power mechanism 5a, when the first surface 6011 of the first housing 601 and the second surface 5011 of the second housing 501 are hollowed-out surfaces, the driving device 502 can be connected to the sliding member 603 through the hollowed-out areas of the first surface 6011 and the second surface 5011. In addition, when the first surface 6011 of the first housing 601 is provided with a first slot and the second surface 5011 of the second housing 501 is provided with a second slot, the driving device 502 can be connected to the sliding member 603 through the first slot and the second slot. At this time, the specific settings of the first slot and the second slot also need to consider the sliding trajectory of the sliding member 603 to avoid interfering with the movement of the sliding member 603.

[0104] It is worth mentioning that in the embodiment of the present application, in order to facilitate the connection between the driving device 502 and the sliding member 603, a part of the sliding member 603 can be located in the second housing 501, and the driving device 502 can be connected to the part of the sliding member 603 located in the second housing 501.

[0105] In addition, in some possible embodiments of the present application, the power mechanism may not be provided with the second housing 501, which can also be understood as that the feeding network 6 and the power mechanism 5 share the first housing 601, which is beneficial to simplifying the structure of the feeding network system and is beneficial to realizing the miniaturization and lightweight design of the feeding network system.

[0106] To facilitate the understanding of the feeding network system provided in the present application, as Figure 9 shown, next, taking the feeding network 6 as a dielectric phase shifter as an example, the specific setting method of the feeding network system will be introduced. Among them, in the dielectric phase shifter, the fixing member 602 includes a metal strip line 6021. The metal strip line 6021 can be, but is not limited to, a sheet metal strip line, and its material can be, but is not limited to, copper. In addition, the fixing member 602 can also include a support frame made of an insulating material ( Figure 9 not shown in the figure), and the support frame can be connected to the first housing 601 and the metal strip line 6021 to support the metal strip line 6021; alternatively, the fixing member 602 includes a printed circuit board, and the metal strip line 6021 is a metal trace in the printed circuit board. In addition, the sliding member 603 in the dielectric phase shifter includes an insulating medium.

[0107] As can be known from the above introduction of the dielectric phase shifter, the metal strip line 6021 can be used to connect to the radiation element of the antenna to achieve the directivity adjustment of the radiation direction of the antenna signal by the dielectric phase shifter. Based on this, it can be understood that the metal strip line 6021 can be provided with a functional circuit for adjusting the phase of the antenna signal. The insulating medium of the slider 603 covers a part of the metal strip line 6021, so that a part of the metal strip line 6021 is covered by the insulating medium, and the other part of the metal strip line 6021 is not covered by the insulating medium. Then, the dielectric constants of the environments where the respective parts of the metal strip line 6021 are located are different. In this way, during the process of the driving mechanism 5a driving the slider 603 to slide relative to the fixed member 602, the part of the metal strip line 6021 covered by the insulating medium changes, resulting in a change in the dielectric constant of the environment where the entire metal strip line 6021 is located, so that the electrical performance of the metal strip line 6021 changes. It can change the electrical length of the antenna signal transmitted through the metal strip line 6021, thereby realizing the adjustment of the phase of the antenna signal by the dielectric phase shifter.

[0108] In this application, the driving device 502 and the slider 603 can be directly connected, that is, the driving device 502 and the slider 603 can be in direct contact and transmission connection, so that the acting force output by the driving device 502 can be directly transmitted to the slider 603, which is beneficial to improving the transmission efficiency of the acting force between the driving device 502 and the slider 603 and is beneficial to reducing the volume of the feed network system.

[0109] When specifically setting the driving device 502, reference can be continued to Figure 9 In this embodiment of the application, the driving device 502 can be a piezoelectric driving device, and when specifically setting it, reference can be made to Figure 10 Figure 10 FIG. is a schematic structural diagram of a driving device 502 provided by an embodiment of the present application. The driving device 502 includes a device fixing frame 5021 and a resonant component 5022. The device fixing frame 5021 is fixedly connected to the first housing 601, or the device fixing frame 5021 is fixedly connected to the second housing 501, or the device fixing frame 5021 is a part of the second housing 501. In this embodiment of the application, the device fixing frame 5021 can be used as a supporting component of the entire driving device 502 to support other structures of the driving device 502.

[0110] Reference can be continued to Figure 9 and Figure 10 The resonant component 5022 is located on the side of the device fixing frame 5021 facing away from the first housing 601. In this application, for the convenience of description, the arrangement direction of the resonant component 5022 and the device fixing frame 5021 can be defined as the Y direction.

[0111] Refer to Figure 11 ​Figure 11 is Figure 10 A schematic structural diagram of the resonant component 5022 of the driving device 502 shown in. The resonant component 5022 includes a metal elastic body 50221 and a piezoelectric material layer 50222. Among them, the material of the metal elastic body 50221 can be a metal material such as stainless steel or phosphor bronze that is prone to deformation. The piezoelectric material layer 50222 can include a plurality of stacked piezoelectric ceramic layers. The piezoelectric material layer 50222 is disposed on at least one surface of the metal elastic body 50221, and the piezoelectric material layer 50222 can be connected to the surface of the metal elastic body 50221 by means of bonding or the like.

[0112] In the embodiment of the present application, the number of piezoelectric material layers 50222 in the resonant component 5022 is not limited, and it can be selected according to specific needs. For example, in Figure 11 the shown resonant component 5022, it includes two piezoelectric material layers 50222. The two piezoelectric material layers 50222 are disposed on the first surface 502211 of the metal elastic body 50221. Among them, the first surface 502211 of the metal elastic body 50221 faces away from the device fixing bracket 5021. In addition, in Figure 11 the shown resonant component 5022, the two piezoelectric material layers 50222 are arranged adjacent to each other. In the embodiment of the present application, for the convenience of description, the arrangement direction of the two piezoelectric material layers 50222 in Figure 11 the shown resonant component 5022 can be defined as the X direction.

[0113] Referring to Figure 12 , Figure 12 is Figure 11 a schematic structural diagram of the resonant component 5022 from another angle shown in. The metal elastic body 50221 further includes driving feet 502213. The driving feet 502213 are disposed on the second surface 502212 of the metal elastic body 50221. The driving feet 502213 protrude from the second surface 502212 along the direction from the first surface 502211 to the second surface 502212. Among them, the second surface 502212 of the metal elastic body 50221 is disposed opposite to the first surface 502211. The present application does not limit the number of driving feet 502213 of the metal elastic body 50221. Exemplarily, in Figure 12 the shown resonant component 5022, the number of driving feet 502213 of the metal elastic body 50221 is two; or in other possible embodiments, the number of driving feet 502213 of the metal elastic body 50221 can also be one, three, four or more.

[0114] In the present application, the metal elastomer 50221 can be an integrally molded structure, that is, the driving foot 502213 is a part of the metal elastomer 50221, the two are made of the same material, and they are processed through a single processing technology to simplify the structure of the metal elastomer 50221 and improve production efficiency; or the driving foot 502213 can be an independent structure, which can be fixed to the second surface 502212 of the metal elastomer 50221 by welding or bonding. At this time, the materials of the driving foot 502213 and the metal elastomer 50221 can be the same or different, which is conducive to improving the setting flexibility of the driving foot 502213.

[0115] You can continue to refer to Figure 11 The resonant component 5022 further includes a power supply module 50223, which is electrically connected to each piezoelectric material layer 50222, so that the power supply module 50223 can be used to apply voltage to each piezoelectric material layer 50222. In this way, when the high-frequency voltage applied by the power supply module 50223 to the two piezoelectric material layers 50222 disposed on the first surface 502211 of the metal elastic body 50221 has a certain phase difference, the metal elastic body 50221 can be driven to deform according to a set rule, for example, the metal elastic body 50221 can be driven to perform a microscopic elliptical motion, thereby driving the driving foot 502213 to move synchronously.

[0116] exist Figure 10 The driving device 502 shown also includes a resonance component bracket 5023 and a resonance component fixing frame 5024, wherein the metal elastic body 50221 of the resonance component 5022 is connected to the resonance component bracket 5023, and the connection method thereof can be but is not limited to threaded connection, welding or riveting.

[0117] The resonant component fixing frame 5024 is located between the device fixing frame 5021 and the resonant component bracket 5023, and the resonant component fixing frame 5024 is fixedly connected to the device fixing frame 5021. The resonant component fixing frame 5024 includes a mounting groove 50241, and the mounting groove 50241 penetrates the resonant component fixing frame 5024 along the arrangement direction of the resonant component fixing frame 5024 and the device fixing frame 5021.

[0118] The resonant component bracket 5023 is installed in the mounting groove 50241 of the resonant component fixing frame 5024, and the resonant component bracket 5023 is overlapped on the side of the resonant component fixing frame 5024 away from the device fixing frame 5021. It is worth mentioning that in the present application, there is no connection between the resonant component bracket 5023 and the resonant component fixing frame 5024, so when the metal elastic body 50221 of the resonant component 5022 performs a microscopic elliptical motion according to a set rule, the resonant component bracket 5023 can be driven to move synchronously with the metal elastic body 50221.

[0119] Continue to refer to Figure 10 In the X direction, the installation groove 50241 includes a first groove wall 502411 and a second groove wall 502412 that are oppositely arranged. A lateral preloading component 5025 is provided between the resonant component bracket 5023 and at least one of the first groove wall 502411 and the second groove wall 502412.

[0120] In this application, the lateral preloading component 5025 includes a lateral preloading elastic member 50251 and a first rolling member 50252. The lateral preloading elastic member 50251 can be, but is not limited to, elastic structural members such as a reed, a wave spring, a compression spring, or a tension spring. Taking the lateral preloading component 5025 being arranged between the resonant component bracket 5023 and the first groove wall 502411 as an example, one end of the lateral preloading elastic member 50251 abuts against the first groove wall 502411, and the other end of the lateral preloading elastic member 50251 abuts against the first rolling member 50252. Thus, under the elastic force of the lateral preloading elastic member 50251, the first rolling member 50252 is pressed towards the end of the resonant component bracket 5023 facing the first groove wall 502411. In this way, during the movement of the resonant component bracket 5023 along with the metal elastic body 50221, the lateral preloading component 5025 can limit the movement of the resonant component bracket 5023 along the arrangement direction of the first groove wall 502411 and the second groove wall 502412, thereby preventing the resonant component bracket 5023 from moving erratically in this direction. Also, because the end face of the resonant component bracket 5023 facing the first groove wall 502411 abuts against the first rolling member 50252, the setting of the lateral preloading component 5025 will not affect the movement of the resonant component bracket 5023 along with the metal elastic body 50221. Therefore, by setting the lateral preloading component 5025 between the resonant component bracket 5023 and the first groove wall 502411, the movement stability of the resonant component bracket 5023 can be effectively improved, thereby improving the movement stability of the resonant component 5022, which is beneficial to improving the stability of the driving force output by the resonant component 5022 through the driving foot 502213.

[0121] It can be understood that, in order to make the first rolling member 50252 stably contact the end of the resonant component bracket 5023, a groove can be provided at the end of the resonant component bracket 5023 facing the first groove wall 502411. Then, at least part of the first rolling member 50252 can be received in the groove, and the side wall of the first rolling member 50252 fits with the groove wall of the groove, so that the first rolling member 50252 can roll relative to the groove.

[0122] In an embodiment of the present application, the first rolling member 50252 may be, for example, a roller. Additionally, a lateral preloading component 5025 may or may not be provided between the resonant component bracket 5023 and the second groove wall 502412. When the lateral preloading component 5025 is provided between the resonant component bracket 5023 and the second groove wall 502412, its specific setting can refer to the above embodiment, and details are not elaborated here. Alternatively, only one first rolling member 50252 may be provided between the resonant component bracket 5023 and the second groove wall 502412 to simplify the structure of the piezoelectric driving device while improving the movement stability of the resonant component bracket 5023.

[0123] The power mechanism provided in the present application further includes a follower 5026, which is used to connect with the slider 603. Then, the follower 5026 can be located between the driving foot 502213 and the slider 603. In the present application, the driving force output by the resonant component 5022 through the driving foot 502213 can act on the follower 5026, thereby driving the follower 5026 to move linearly. During specific implementation, reference can continue to be made to Figure 10 , along the Y direction, the follower 5026 is located between the device fixing bracket 5021 and the resonant component 5022. The surface of the follower 5026 facing the resonant component 5022 abuts against the driving foot 502213 of the resonant component 5022, so that the follower 5026 moves with the driving foot 502213 under the friction force between it and the driving foot 502213.

[0124] Since the friction force between the follower 5026 and the driving foot 502213 is the key to ensuring the movement stability of the follower 5026, in order to increase the friction force between the follower 5026 and the driving foot 502213, the piezoelectric driving device provided in the present application further includes a friction member 5027. In Figure 10 the shown driving device 502, the friction member 5027 is provided on the surface of the follower 5026 facing the resonant component 5022, and the driving foot 502213 of the resonant component 5022 can abut against the friction plate 50271.

[0125] In the present application, the friction member 5027 can be a metal sheet, and the friction member 5027 is fixedly connected to the surface of the follower 5026 facing the resonant component 5022. The connection method can be, but is not limited to, welding, bonding, or clamping, etc. Alternatively, the friction member 5027 and the follower 5026 are an integrally formed structure, and the friction member 5027 can be a part with a relatively large friction coefficient formed on the surface of the follower 5026 facing the resonant component 5022 through a grinding process.

[0126] In addition, in order to ensure that the driving foot 502213 of the resonance component 5022 abuts against the driven member 5026, the driving device provided in the embodiment of the present application further includes a positive pre-compression component 5028, which is located on the side of the resonance component 5022 away from the device fixing frame 5021, and the positive pre-compression component 5028 presses the resonance component 5022 toward the driven member 5026 under the action of elastic force. Figure 10 As shown, the positive preload component 5028 may include a positive preload elastic member 50281 and a pressure plate 50282. The positive preload elastic member 50281 may be located on a side of the pressure plate 50282 away from the resonance component 5022, so that the positive preload elastic member 50281 presses the pressure plate 50282 toward the resonance component 5022 under the action of elastic force, thereby pressing the resonance component 5022 toward the follower 5026. In the present application, the positive preload elastic member 50281 may be, but is not limited to, an elastic structural member such as a leaf spring, a wave spring, a compression spring, or a tension spring.

[0127] exist Figure 10 In the driving device 502 shown, a receiving groove 502821 may be further provided on the side of the pressure plate 50282 facing the positive preload elastic member 50281, and a portion of the positive preload elastic member 50281 may be received in the receiving groove 502821 of the pressure plate 50282 to improve the structural reliability of the positive preload assembly 5028.

[0128] It is worth mentioning that in Figure 10 In the driving device 502 shown, since the piezoelectric material layer 50222 is located on the side of the metal elastic body 50221 facing the forward preloading component 5028, in order to prevent the forward preloading component 5028 from damaging the piezoelectric material layer 5022, the piezoelectric driving device may further include a buffer pad 5029, which is located between the forward preloading component 5028 and the resonance component 5022, and the forward preloading component 5028 presses the buffer pad 5029 toward the resonance component 5022 under the action of elastic force. The present application does not limit the material of the buffer pad 5029, which may be a flexible material layer such as foam.

[0129] You can continue to refer to Figure 10, the piezoelectric driving device further includes a cover plate 50210. The forward preloading assembly 5028 is located between the cover plate 50210 and the resonant assembly 5022, and the cover plate 50210 is fixedly connected to the resonant assembly fixing frame 5024. The connection method can be but is not limited to threaded connection, so that the cover plate 50210 and the resonant assembly fixing frame 5024 are detachably connected, which is convenient for overhauling or replacing the resonant assembly 5022. In some possible embodiments, the cover plate 50210 and the resonant assembly fixing frame 5024 can also be fixedly connected by welding, bonding or riveting, etc., to improve the connection reliability between the cover plate 50210 and the resonant assembly fixing frame 5024.

[0130] In addition, it can be understood that the forward preloading elastic member 50281 of the forward preloading assembly 5028 is located between the cover plate 50210 and the pressing plate 50282. The forward preloading elastic member 50281 can be abutted against the cover plate 50210 and the pressing plate 50282, and the pressing plate 50282 is abutted against the resonant assembly 5022. In this way, the forward preloading assembly 5028 can be pressed against the resonant assembly 5022 through the connection between the cover plate 50210 and the resonant assembly fixing frame 5024, so that the forward preloading assembly 5028 applies a normal positive pressure to the resonant assembly 5022, so that the forward preloading assembly 5028 presses the driving foot 502213 of the resonant assembly 5022 against the driven member 5026.

[0131] As can be seen from the above introduction, the driven member 5026 can move linearly relative to the device fixing frame 5021 under the drive of the resonant assembly 5022. In order to improve the movement stability of the driven member 5026, as Figure 10 shown, the device fixing frame 5021 includes a guide groove 50211. It can be understood that the guide groove 50211 is a linear sliding groove, and the guide groove 50211 extends along the X direction. In addition, the driven member 5026 can also include a slider ( Figure 10 not shown in the figure). The slider can be located on the surface of the driven member 5026 facing away from the resonant assembly 5022. The slider can be inserted into the guide groove 50211. Then, under the drive of the resonant assembly 5022, the slider of the driven member 5026 can slide along the guide groove 50211.

[0132] To improve the smoothness of the movement of the follower 5026 relative to the device fixing bracket 5021, the driving device 502 provided in the embodiment of the present application further includes a second rolling member 502110. The second rolling member 502110 is located between the follower 5026 and the device fixing bracket 5021, and both the follower 5026 and the device fixing bracket 5021 are in contact with the surface of the second rolling member 502110. In this way, during the movement of the follower 5026 relative to the device fixing bracket 5021, the friction pair between the follower 5026 and the device fixing bracket 5021 is a rolling friction pair, which can make the resistance of the relative movement between the follower 5026 and the device fixing bracket 5021 smaller, thereby facilitating the reduction of the power consumption of the driving device 502.

[0133] In the present application, the specific type of the second rolling member 502110 is not limited, and it can be, for example, a roller or a ball. It can be understood that, in order to improve the movement reliability of the second rolling member 502110, at least one of the device fixing bracket 5021 and the follower 5026 can also be provided with a limiting groove 50212. For example, in Figure 10 the device fixing bracket 5021 is provided with a limiting groove 50212, and at least part of the second rolling member 502110 can be accommodated in the limiting groove 50212. In the embodiment of the present application, the device fixing bracket 5021 and the follower 5026 can also be both provided with limiting grooves 50212, and the limiting grooves 50212 of the two are arranged oppositely. In this way, part of the second rolling member 502110 is located in the limiting groove 50212 of the device fixing bracket 5021, and part of the second rolling member 502110 is located in the limiting groove 50212 of the follower 5026.

[0134] The present application does not limit the number of the second rolling members 502110, and it can be, for example, two, three or more, which can be specifically set according to the installation space between the device fixing bracket 5021 and the follower 5026. In addition, the present application does not limit the shape of the limiting groove 50212. Exemplarily, the cross-sectional shape of the limiting groove 50212 of the device fixing bracket 5021 can be V-shaped or U-shaped, etc., and the cross-sectional shape of the limiting groove 50212 of the follower 5026 can be V-shaped or U-shaped, etc., so as to prevent the second rolling member 502110 from slipping out between the device fixing bracket 5021 and the follower 5026.

[0135] In the present application, in order to facilitate the connection between the follower 5026 and the sliding member 603, refer to Figure 13 , Figure 13 For Figure 10The enlarged view of the local structure at B. The end of the follower 5026 facing the sliding member 603 includes a protrusion 50262, and the end of the sliding member 603 facing the follower 5026 includes a groove 6031. Alternatively, in some possible embodiments, the end of the sliding member 603 facing the follower 5026 includes a protrusion, and the end of the follower 5026 facing the sliding member 603 includes a groove. In this way, the follower 5026 and the sliding member 603 can be connected by a snap-fitting manner by inserting the protrusion into the groove.

[0136] In addition, refer to Figure 14 , Figure 14 Schematic diagram of another connection mode between the driven member 5026 and the sliding member 603 provided in the embodiment of the present application. The end of the driven member 5026 facing the sliding member includes a gear 50263, and the end of the sliding member 603 facing the driven member 5026 includes a rack surface 6032, and the gear surface of the gear 50263 meshes with the rack surface 6032. Thus, the driven member 5026 and the sliding member 603 are connected in a transmission manner by meshing the gear surface with the rack surface 6032.

[0137] Based on the above introduction to the connection method between the follower 5026 and the sliding member 603, the connection method between the two can also be adaptively modified. For example, the follower 5026 and the sliding member 603 can also be provided with hooks, and the two can be connected by the hooks, or the two can be connected by welding, riveting or threaded connection, etc. They are not listed one by one here, but they should all be understood to fall within the scope of protection of this application.

[0138] The power mechanism 5a provided in the above embodiment of the present application, by making the driving foot 502213 of the metal elastic body 50221 of the resonant component 5022 in frictional contact with the follower 5026, to convert the microscopic motion of the resonant component 5022 into the macroscopic linear motion of the follower 5026, thereby directly outputting the linear driving force by piezoelectric driving, which omits the intermediate transmission mechanism, so that the structure of the power mechanism is relatively simple, the volume is small and the weight is light. When the power mechanism 5a is applied to the feeding network system, it is conducive to the miniaturization and lightweight design of the feeding network system. In addition, since no magnetic structural parts are provided in the power mechanism 5a, when the feeding network system including the power mechanism 5a is used for the antenna, interference with the antenna signal can be avoided, which is conducive to improving the signal radiation performance of the antenna.

[0139] Based on the above-mentioned embodiment, the driving principle of the driving device 502 provided in the present application can be modified in a series of ways. Figure 15 , Figure 15Another structural schematic diagram of the driving device 502 provided by the embodiment of the present application. Figure 15 The shown driving device 502 is slightly different from the above embodiment. Specifically, Figure 15 In the shown driving device 502, the resonance component 5022 includes four piezoelectric material layers 50222. Two of the four piezoelectric material layers 50222 are disposed on the first surface 502211 of the metal elastic body 50221, and the other two of the four piezoelectric material layers 50222 are disposed on the second surface 502212 of the metal elastic body 50221. Figure 15 Only the two piezoelectric material layers 50222 disposed on the first surface 502211 of the metal elastic body 50221 are shown. In this embodiment of the present application, the arrangement directions of the two piezoelectric material layers 50222 disposed on the first surface 502211 of the metal elastic body 50221 are the same as those of the two piezoelectric material layers 50222 disposed on the second surface 502212 of the metal elastic body 50221, and they are all arranged along the X direction.

[0140] In addition, referring to Figure 16 , Figure 16 is Figure 15 an exploded view of the driving device 502 shown in

[0141] In a possible embodiment of the present application, the two piezoelectric material layers 50222 disposed on the first surface 502211 of the metal elastic body 50221 and the two piezoelectric material layers 50222 disposed on the second surface 502212 of the metal elastic body 50221 can be arranged in one-to-one correspondence, so that the two piezoelectric material layers 50222 disposed on the first surface 502211 of the metal elastic body 50221 and the two piezoelectric material layers 50222 disposed on the second surface 502212 of the metal elastic body 50221 are symmetrically arranged with respect to the metal elastic body 50221, which is beneficial to the miniaturized design of the resonance component 5022, and thus beneficial to the reduction of the volume of the driving device 502.

[0142] Continue to refer to Figure 16, the driving feet 502213 of the metal elastomer 50221 are two, and the two driving feet 502213 are located on both sides of the above-mentioned hollow area 502214. The arrangement direction of the two driving feet 502213 intersects with the arrangement direction of the two piezoelectric material layers 50222 provided on the same surface of the metal elastomer 50221. Exemplarily, the arrangement direction of the two driving feet 502213 is perpendicular to the arrangement direction of the two piezoelectric material layers 50222 provided on the same surface of the metal elastomer 50221. In addition, each driving foot 502213 protrudes from the corresponding side surface of the metal elastomer 50221 in the direction away from the hollow area 502214.

[0143] As Figure 16 shown, the friction member 5027 is located on the side of the driven member 5026 facing the resonance assembly 5022, and the friction member 5027 is connected to the surface of the driven member 5026 facing the resonance assembly 5022. The connection method can be but is not limited to welding, bonding or clamping, etc. In addition, the friction member 5027 includes two relatively arranged friction plates 50271, which can be referred to together with Figure 15 and Figure 16 , the metal elastomer 50221 is located between the two friction plates 50271, and the two driving feet 502213 are in one-to-one contact with the two friction plates 50271. In the driving device 502 shown in the present application Figure 16 , the surface of the driven member 5026 facing the resonance assembly 5022 may further include a fixing frame 50264. The fixing frame 50264 protrudes from the surface of the driven member 5026 in the direction from the driven member 5026 to the resonance assembly 5022. Then the two friction plates 50271 can be connected to the fixing frame 50264, which can improve the connection convenience and reliability between the friction plates 50271 and the driven member 5026.

[0144] It can be further referred to Figure 15 and Figure 16 , the forward preloading assembly 5028 is connected to the surface of the driven member 5026 facing the resonance assembly 5022. The connection method can be but is not limited to welding, bonding or clamping, etc. The forward preloading assembly 5028 abuts against the surface of each friction plate 50271 facing away from the metal elastomer 50221, and the forward preloading assembly 5028 can apply a normal positive pressure to each friction plate 50271, so that the forward preloading assembly 5028 presses each friction plate 50271 against the corresponding driving foot 502213 under the action of elastic force.

[0145] It is worth mentioning that in the present application Figure 16In the driving device 502 shown, the forward preloading assembly 5028 may include a claw-shaped spring piece. At least one elastic claw portion of the claw-shaped spring piece abuts against the surface of a friction plate 50271 facing away from the metal elastic body 50221, and at least one elastic claw portion of the claw-shaped spring piece abuts against the surface of another friction plate 50271 facing away from the metal elastic body 50221, so as to apply a normal positive pressure to each friction plate 50271, thereby pressing each friction plate 50271 against the corresponding driving foot 502213. In addition, in order to increase the frictional force between the friction plate 50271 and the driving foot 502213, the extrusion force applied by the forward preloading assembly 5028 to the friction plate 50271 can be increased. Specifically, in implementation, the forward preloading assembly 5028 may include two or more claw-shaped spring pieces, and at least one elastic claw portion of each claw-shaped spring piece abuts against the surface of a friction plate 50271 facing away from the metal elastic body 50221, and at least one elastic claw portion of each claw-shaped spring piece abuts against the surface of another friction plate 50271 facing away from the metal elastic body 50221. In addition, two or more claw-shaped spring pieces of the forward preloading assembly 5028 are detachably connected to improve the setting flexibility of the forward preloading assembly 5028.

[0146] Figure 15 and Figure 16 The other structures of the driving device 502 shown can be set with reference to any of the above embodiments, and will not be elaborated herein.

[0147] In Figure 15 and Figure 16 In the driving device 502 shown, if the voltages applied by the power supply module 50223 to the two piezoelectric material layers 50222 provided on the same side surface of the metal elastic body 50221 are the same, then when there is a certain phase difference between the high-frequency voltages applied by the power supply module 50223 to the piezoelectric material layers 50222 provided on the two surfaces of the metal elastic body 50221, the metal elastic body 50221 can form a certain regular microscopic elliptical motion, thereby driving the driving foot 502213 to move synchronously. Also, because each driving foot 502213 abuts against the corresponding friction plate 50271, under the action of the frictional force between the driving foot 502213 and the corresponding friction plate 50271, the driving foot 502213 drives the friction plate 50271 to move linearly, so as to convert the microscopic motion of the resonance assembly 5022 into the macroscopic linear motion of the friction plate 50271. Also, since the friction plate 50271 is connected to the driven member 5026, the driven member 5026 can be made to move linearly synchronously with the friction plate 50271.

[0148] Refer to Figure 17 , Figure 17Another structural schematic diagram of the driving device 502 provided by the embodiment of the present application. In this driving device 502, the resonance component 5022 further includes a driving shaft 50224 in addition to the metal elastic body 50221 and the piezoelectric material layer 50222. When specifically arranging this resonance component 5022, reference can be made to Figure 18 , Figure 18 is Figure 17 the exploded view of the driving device 502 shown. Among them, the resonance component 5022 includes two piezoelectric material layers 50222. One piezoelectric material layer 50222 is arranged on the first surface 502211 of the metal elastic body 50221, and the other piezoelectric material layer 50222 is arranged on the second surface 502212 of the metal elastic body 50221. The driving shaft 50224 passes through the two piezoelectric material layers 50222 and the metal elastic body 50221, and the driving foot of the metal elastic body 50221 ( Figure 18 not shown in the figure) is connected to the driving shaft 50224, and the connection method can be but is not limited to bonding. In this way, the driving shaft 50224 can move synchronously with the driving foot, so the driving shaft 50224 can also be understood as the driving foot of the metal elastic body 50221.

[0149] The resonance component 5022 is located on one side of the device fixing frame 5021. The device fixing frame 5021 includes a first mounting portion 50213 and a second mounting portion 50214 which are oppositely arranged. The first mounting portion 50213 includes a first mounting hole 502131, and the second mounting portion 50214 includes a second mounting hole 502141. The driving shaft 50224 sequentially passes through the first mounting hole 502131 and the second mounting hole 502141, so that both ends of the driving shaft 50224 are respectively mounted on the first mounting portion 50213 and the second mounting portion 50214. In addition, in the present application, the metal elastic body 50221 can be connected to the first mounting portion 50213 to realize the connection between the metal elastic body 50221 and the device fixing frame 5021.

[0150] Continue to refer to Figure 18 , in this driving device 502, the friction member 5027 includes two clamping portions 50272. The two clamping portions 50272 are buckled and arranged on both sides of the driving shaft 50224, so that the driving shaft 50224 is clamped between the two clamping portions 50272. In this way, the friction member 5027 can make a linear motion along the driving shaft 50224 under the drive of the high-frequency linear vibration output by the above resonance component 5022.

[0151] In addition, the forward preloading component 5028 can be used to apply a normal positive pressure to the two clamping parts 50272 respectively, so as to press the two clamping parts 50272 towards the driving shaft 50224, that is, to press the friction part 5027 towards the driving shaft 50224, so that the two clamping parts 50272 clamp the driving shaft 50224, thereby increasing the friction force between the clamping part 50272 and the driving shaft 50224. In this embodiment of the present application, the forward preloading component 5028 may include two reed pieces, and the two reed pieces are respectively located at two opposite ends of the friction part 5027, and the two reed pieces are connected to the corresponding ends of the two clamping parts 50272, and the connection method may but is not limited to threaded connection, so that each reed piece presses the corresponding ends of the two clamping parts 50272 together.

[0152] Reference may be made together to Figure 17 and Figure 18 , the friction part 5027 is located between the device fixing frame 5021 and the driven part 5026, and a first clamping part 50267 is arranged on the surface of the driven part 5026 facing the friction part 5027. In addition, the two clamping parts 50272 of the friction part 5027 are arranged along the direction from the device fixing frame 5021 to the driven part 5026. For the convenience of description, the two clamping parts 50272 can be respectively named as the first clamping part 50272 and the second clamping part 50272. Among them, the first clamping part 50272 is closer to the driven part 5026 than the second clamping part 50272, and a second clamping part ( Figure 18 not shown in ) may be arranged on the surface of the first clamping part 50272 facing the driven part 5026. In this way, the first clamping part 50267 of the driven part 5026 can be clamped with the second clamping part of the first clamping part 50272, so that the first clamping part 50272 is clamped with the driven part 5026, thereby realizing the clamping of the driven part 5026 and the friction part 5027, so that the friction part 5027 can drive the driven part 5026 to move linearly with it.

[0153] In the embodiment of the present application, the first clamping part 50267 can be a protrusion or a groove, and the second clamping part can be a groove or a protrusion, as long as the clamping of the driven part 5026 and the first clamping part 50272 can be realized. Of course, the driven part 5026 and the friction part 5027 can also be connected in other possible ways, which will not be introduced one by one here, but they should all be understood to fall within the protection scope of the present application. In addition, in another possible embodiment of the present application, the first clamping part 50272 and the driven part 5026 can also be an integrally formed structure, which is beneficial to improving the movement consistency between the driven part 5026 and the friction part 5027, thereby improving the driving accuracy of the displacement of the driven part 5026 by the resonant component 5022, and further beneficial to improving the adjustment accuracy of the electrical parameters of the feed network system to which the driving device is applied.

[0154] Figure 17 Other structures of the driving device 502 shown can be set with reference to any of the above embodiments, and will not be elaborated here.

[0155] In the embodiments of the present application, in addition to the form of the driving device 502 of the power mechanism 5a based on the piezoelectric driving principle as described above, it can also be some other miniaturized driving devices. Exemplarily, reference can be made to Figure 19 , in Figure 19 In the feeding network system shown, the driving device 502 of the power mechanism 5a includes a micro motor ( Figure 19 not shown). In addition, the power mechanism 5a further includes a gear 503 and a rack 504, and the gear 503 and the rack 504 can be used as driven members in the power mechanism 5a. Specifically in implementation, the gear 503 meshes with the rack 504, and the rack 504 is connected to the sliding member 603. In this embodiment, the micro motor is used to drive the gear 503 to rotate, so that the rotation of the gear 503 can be converted into the linear motion of the rack 504, so as to drive the rack 504 to move linearly by the gear 503, and further drive the sliding member 603 to move linearly by the rack 504.

[0156] It is worth mentioning that in the above Figure 19 shown embodiment, the rack 504 can be an independent structural member, and the connection between the rack 504 and the sliding member 603 can be made with reference to the connection manner between the driven member 5026 and the sliding member 603 in the Figure 13 and Figure 14 shown embodiments, and will not be elaborated here. In addition, in some possible embodiments, the rack 504 and the sliding member 603 can also be integrally formed structures, that is, a rack surface is provided at the end of the sliding member 603 facing the driving device 502, which can effectively simplify the structure of the power mechanism 5a and make the structure of the feeding network system more compact, so as to be beneficial to the miniaturized design of the feeding network system.

In addition, the power mechanism 5a further includes a worm gear 505 and a worm 506, and the worm gear 505 and the worm 506 can be used as driven members in the power mechanism 5a. Specifically in implementation, the worm gear 505 meshes with the worm 506, and the worm 506 is connected to the sliding member 603. In this embodiment, the micro motor can be used to drive the worm gear 505 to rotate, so that the rotation of the worm gear 505 can be converted into the linear motion of the worm 506, thereby driving the sliding member 603 to move linearly by the worm 506.

[0158] It is worth mentioning that in the above Figure 20 shown embodiment, the worm 506 and the slider 603 can also refer to the above Figure 13 and Figure 14 shown connection method between the follower 5026 and the slider 603 in the embodiment, and details thereof will not be elaborated herein. Additionally, Figure 20 other structures of the shown feed network system can be set with reference to any of the above embodiments, and details thereof will not be elaborated herein.

[0159] Additionally, in a possible embodiment of the present application, the power mechanism 5a can further include a worm gear 505, and the slider 603 can include a worm 506. In this way, the transmission connection between the power mechanism 5a and the slider 603 can also be realized by the meshing of the worm gear 505 and the worm 506, which can make the power mechanism 5a and the feed network 6 more compactly designed, thus facilitating the miniaturization of the feed network system.

[0160] Referring to Figure 21 , Figure 21 which is another schematic structural diagram of the feed network system provided by the embodiment of the present application. In this feed network system, the driving device 502 of the power mechanism 5a also includes a micro motor ( Figure 21 not shown). Additionally, the power mechanism 5a further includes a worm 506 and a rack 504, and the worm 506 and the rack 504 can be used as followers in the power mechanism 5a. Specifically in implementation, the worm 506 meshes with the rack 504, the rack 504 is connected to the slider 603, and additionally, the micro motor can be used to drive the worm 506 to rotate. In this way, the rotation of the worm 506 can be converted into the linear motion of the rack 504, so that the rack 504 drives the slider 603 to move linearly.

[0161] It is worth mentioning that in the above Figure 21 shown embodiment, the rack 504 can be an independent structural member, and the connection between the rack 504 and the slider 603 can refer to the above Figure 13 and Figure 14 shown connection method between the follower 5026 and the slider 603 in the embodiment, and details thereof will not be elaborated herein. Additionally, in some possible embodiments, the rack 504 and the slider 603 can also be an integrally formed structure, that is, a rack surface is provided at the end of the slider 603 facing the driving device 502. In this way, the structure of the power mechanism 5a can be effectively simplified, and the structure of the feed network system can be made more compact, which is beneficial to the miniaturization design of the feed network system.

[0162] Referring to Figure 22 , Figure 22Another structural schematic diagram of the feeding network system provided by the embodiment of the present application. In this feeding network system, the driving device 502 of the power mechanism 5a includes a linear motor 502120, and the output end of the linear motor 502120 can be directly connected to the sliding member 603 to drive the sliding member 603 to move linearly through the linear motor 502120. Since in this embodiment, the linear force output by the linear motor 502120 can directly act on the sliding member 603, and an intermediate transfer member may not be provided therebetween, which is beneficial to the simplification of the structure of the power mechanism 5a, and thus beneficial to the miniaturized design of the feeding network system.

[0163] The above embodiments are only some exemplary descriptions of the driving device 502 of the power mechanism 5a of the feeding network system provided by the present application. On this basis, some appropriate deformations can also be made to the driving device 502. For example, the structure of the follower provided between the driving device 502 and the sliding member 603 can be adjusted to enable the sliding member 603 to move along a set curve, etc. They will not be listed one by one here, but they should all be understood to fall within the protection scope of the present application.

[0164] In the present application, in addition to being a dielectric phase shifter, the feeding network 6 can also be a feeding network in other possible setting forms. Exemplarily, in Figure 23 the shown feeding network system, the feeding network 6 is a physical phase shifter. Among them, in this feeding network 6, the fixing member 602 includes a metal strip line 6021, and a functional circuit is provided on the metal strip line 6021. Among them, the metal strip line 6021 can be a sheet metal strip line, and its material can be but not limited to copper.

[0179] In addition, when applying the feeding network system provided in the above embodiments of the present application to an antenna, the antenna can be made to include at least two such feeding network systems.
