Description

Technical Field

[0001] The present invention belongs to the technical field of mobile communications, and in particular relates to an antenna and an antenna controller thereof. Background Art

[0002] As the number of mobile communication terminal users continues to increase, the demand for network capacity of sites in mobile cellular networks is increasing. At the same time, it is required to minimize the interference between different sites or even between different sectors of the same site, that is, to maximize network capacity and minimize interference. To achieve this goal, it is usually achieved by adjusting the downtilt angle of the antenna beam on the site.

[0003] Among the two ways to adjust the beam downtilt angle, mechanical downtilt and electronic downtilt, electronic downtilt has obvious advantages and is the current mainstream and future development trend. The control of electrical downtilt angle is mainly divided into two categories: internal and external, among which internal control is the current and future mainstream.

[0004] However, the motor used to drive the phase shifter in the traditional transmission device still corresponds to the transmission mechanism of the phase shifter one by one, the number of motors has not decreased, and the driving circuit in the control module has not decreased either. If the frequency band of the antenna continues to increase, the transmission system structure will become more complex and bulky, affecting the reliability of the multi-frequency antenna. In addition, the layout of the transmission system is difficult, there are very few options for the transmission system, and the cost is relatively high.

[0005] The applicant has implemented relevant technical solutions to the above problems, but there is still room for improvement in terms of stable control and simple operation.

[0011] Furthermore, the switching component controls the same clutch component an odd number of times, causing the clutch component to engage in gear, and controls the same clutch component an even number of times, causing the clutch component to disengage in gear; or, the switching component controls the same clutch component an even number of times, causing the clutch component to engage in gear, and controls the same clutch component an odd number of times, causing the clutch component to disengage in gear.

[0014] The elastic component is fixed near one end of the external gear, the steering shaft is arranged closely to the elastic component, the driving shaft is arranged closely to the steering shaft and exposed at the other end of the sleeve, and the steering shaft and the driving shaft are both provided with slide rails matching the slideway.

[0015] Furthermore, the driving shaft is acted upon by the second torque of the switching component to push the steering shaft to compress the elastic component, so that the steering shaft in the open state disengages from the slide at the end of the compression stroke and rotates back into the self-locking state, or the steering shaft in the self-locking state releases the self-locking state and rotates to restore the open state.

[0016] Furthermore, the elastic component includes an axial pin and a spring sleeved on the axial pin.

[0017] Furthermore, the ribs forming the slideway and the slide rail are provided with mutually matching slopes at the ends facing each other, and in the self-locking state, the slopes are mutually locked.

[0018] Furthermore, the plurality of clutch assemblies are arranged circumferentially, the transmission assembly of the control mechanism is placed between the clutch assemblies, the transmission assembly is provided with a transmission gear that meshes with each of the controlled gears at the same time, and the transmission assembly is controlled by the first motor to provide the first torque.

[0019] Furthermore, the switching assembly of the control mechanism includes a gear plate and a wedge-shaped piece arranged on the plate surface of the gear plate, the wedge-shaped piece is used to push the driving shaft of each self-locking rebounder, the gear plate is coaxially arranged with the transmission assembly, and the gear plate is controlled by a second motor to drive the wedge-shaped piece to provide the second torque.

The antenna also comprises the above-mentioned antenna controller, and the antenna controller is used to simultaneously couple a plurality of the phase shifting components to implement synchronous phase shifting control of any number of the phase shifting components.

For example, the self-locking rebounder can achieve self-locking after engaging gears, and can be unlocked after the second operation, so it is possible to achieve simultaneous control of multiple clutch components, or selective control of any number of clutch components. When the actuator component and the shifting mechanism are engaged in gear, a phase shift operation is performed under the action of the first torque transmission, so the phase shift operation of the antenna controller can be flexibly controlled according to demand. The ingenious combination of the self-locking rebounder of the antenna controller of the present invention with the control mechanism, the shifting mechanism and the actuator makes the antenna controller provided by the present invention simple in structure, easy to operate, and can quickly switch to achieve high-precision transmission.

[0037] like Figure 1 As shown, an antenna controller provided by the present invention includes a control mechanism 1, a shift mechanism 2 and an actuator 3. The control mechanism 1 includes a transmission component 11 for outputting or transmitting a first torque and a switching component 12 for outputting a second torque. The actuator 3 includes a plurality of actuator components 31. When the actuator components 31 are in a state of being engaged with the shift mechanism 2, they are subjected to the first torque transmission and perform a phase shift operation.

[0038] The actuator 31 includes a screw-nut mechanism 311 and an operating gear 310 located at one end of the screw-nut mechanism 311. The screw-nut mechanism 311 is composed of a screw 3111 and a nut 3112 sleeved on the screw 3111, and the operating gear 310 is fixed to one end of the screw 3111. The nut 3112 is connected to an external phase shifter to drive an external control component that implements a phase shift operation. Multiple actuators 31 are used to phase-adjust antennas of corresponding multiple frequency bands. In other embodiments, the actuator 31 can also be a rack structure combined with an operating gear 310. Under the action of the first torque transmission, the operating gear 310 drives the rack to move accordingly to perform phase adjustment on the antennas of corresponding multiple frequency bands. The structural design of the actuator 31 can be determined according to specific needs and is not limited to the embodiments listed above.

[0039] The shift mechanism 2 is provided with a plurality of clutch assemblies 21 corresponding to the plurality of actuator assemblies 31. The clutch assembly 21 includes a self-locking rebounder 210 and an external gear 211 fixed to one end of the self-locking rebounder 210. The self-locking rebounder 210 is controlled by the second torque switching of the switching assembly 12 to make the clutch assembly 21 and the corresponding actuator assemblies 31 engaged or disengaged. The external gear 211 is used to mesh or disengage with the operating gear 310 of the actuator assemblies 31 corresponding to the clutch assembly 21 to achieve gear engagement or disengagement.

[0040] Specific, combined Figure 2 As shown, the self-locking rebounder 210 includes a sleeve 212, a controlled gear 213 fixed on the sleeve 212 and driven by a first torque to rotate the sleeve 212, and an elastic component 214, a steering shaft 215 and a driving shaft 216 installed inside the sleeve 212.

[0041] The sleeve 212 includes an upper end and a lower end. The lower end of the sleeve 212 is close to the actuator 3, and the upper end of the sleeve 212 is close to the control mechanism 1. The controlled gear 213 is arranged at the lower end of the sleeve 212 and is located at the position connected to the upper end of the sleeve 212.

[0042] Combination Figures 3 to 5As shown, the upper end of the sleeve 212 is connected with the steering shaft 215. An axial slideway 2120 is provided inside the upper end of the sleeve 212, and the steering shaft 215 is provided with a steering shaft slide rail 2150 that matches the slideway 2120. A slope portion A is provided at the rib of the slide rail 2150 of the steering shaft 215, and a slope portion B is provided at the rib of the slideway 2120. The slope portion A and the slope portion B are arranged facing each other, and can be mutually locked or separated under the action of external force. The driving shaft 216 includes a driving shaft slide rail 2160 that matches the slideway 2120 of the sleeve 212, an exposed portion 2161 exposed to the sleeve 212, and a groove C composed of a plurality of slopes located at the opposite end of the exposed portion 2161 of the driving shaft 216, and the plurality of grooves C are continuously arranged on the periphery of the end of the driving shaft 216 to form a circle. In this embodiment, the groove C is an angular groove, and a plurality of angular groove bodies form teeth to form a circle.

[0043] The elastic component 214 includes an axial pin 2140 and a spring 2141 sleeved on the axial pin 2140, which is fixed inside the lower end of the sleeve 212, that is, close to one end of the external gear 211. The steering shaft 215 is arranged adjacent to the axial pin 2140 of the elastic component 214. The axial pin 2140 can make a linear motion back and forth inside the sleeve 212. When the axial pin 2140 moves toward one end of the actuator 3, it pushes the external gear 211 to move toward the actuator 3. At this time, the axial pin 2140 has a thrust on the spring 2141. The other end of the spring 2141 contacts the end of the sleeve 212, so that when the spring 2141 is compressed by the axial pin 2140, it has a reverse thrust on the axial pin 2140. The driving shaft 216 is arranged adjacent to the steering shaft 215 on the sleeve 212, and the exposed portion 2161 of the driving shaft 216 is exposed at the upper end of the sleeve 212, close to the control mechanism 1.

[0044] The slideway 2120 at the upper end of the sleeve 212 cooperates with the slide rails 2150 and 2160 of the pushing shaft 216 and the steering shaft 215 to be connected to each other. Under the action of external force, the exposed portion 2161 of the pushing shaft 216 is pushed, so that the pushing shaft 216 moves inside the upper end of the sleeve 212 toward the lower end, thereby pushing the steering shaft 215 to move toward the lower end of the sleeve 212. The top end of the groove C of the push shaft 216 contacts the slope A of the steering shaft 215, pushing the steering shaft 215 to move forward (toward the lower end of the sleeve 212), and the steering shaft 215 gradually escapes from the slideway 2120 inside the sleeve 212. After the steering shaft 215 escapes from the slideway 2120 of the sleeve 212, since the groove C and the slope A both have a certain slope and are arranged opposite to each other, when the push shaft 216 continues to push the steering shaft 215, the slope A of the steering shaft 215 slides toward the bottom of the groove C, forcing the rotating shaft 216 to rotate along the slope direction of the groove C, so that the slope A falls into the groove C. When the push shaft 216 is pushed, the steering shaft 215 simultaneously gives a forward driving force to the axial pin 2140, and the axial pin 2140 moves toward the lower end of the sleeve 212, while compressing the spring 2141. When the pushing shaft 216 stops, the spring 2141 exerts a reverse thrust on the axial pin 2140, causing the axial pin 2140 to push the steering shaft 215 in the reverse direction. At this time, the slope A of the steering shaft 215 falls into the slope B of the sleeve 212, and the slope A of the steering shaft 215 and the slope B of the sleeve 212 are mutually locked, so that the axial pin 2140 moves toward the lower end of the sleeve 212 for a certain displacement and then fixes its position. The present invention refers to the state in which the slope A of the steering shaft 215 and the slope B of the sleeve 212 are mutually locked as a self-locking state.

[0045] When the clutch assembly 21 is in the self-locking state, the driving force of the driving shaft 216 toward the lower end of the sleeve 212 is given again, and the driving shaft 216 forces the steering shaft 215 to rotate along the slope direction of the groove C, so that the slope portion A of the steering shaft 215 leaves the position corresponding to the slope portion B of the sleeve 212. When the driving of the driving shaft 216 is stopped, the reverse driving force of the spring 2141 on the steering shaft 215 causes the slope portion A of the steering shaft 215 to enter the slideway 2120 of the sleeve 212. At this time, the slope portion A of the steering shaft 215 is separated from the slope portion B of the sleeve 212, and the axial pin 2140 moves toward the upper end of the sleeve 212 under the force of the spring 2141, and returns to the position before the self-locking state. The present invention refers to the state in which the slope portion A of the steering shaft 215 is separated from the slope portion B of the sleeve 212 as the open state.

[0046] When the clutch assembly 21 is in the open state, a driving force is applied to the driving shaft 216 toward the lower end of the sleeve 212 again, and the clutch assembly 21 enters the self-locking state again, and the cycle continues.

[0047] The external gear 211 of the clutch assembly 21 is fixedly connected to the end of the axial pin 2140. When the clutch assembly 21 is in the self-locking state, the end of the axial pin 2140 is pushed out of the lower end of the sleeve 212, thereby pushing the external gear 211 to mesh with the operating gear 310 of the actuator 3. The state in which the external gear 211 is meshed with the operating gear 310 is called the gear-engaging state. When the clutch assembly 21 changes from the self-locking state to the open state, the axial pin 2140 is pushed toward the upper end of the sleeve 212 by the spring 2141, so that the axial pin 2140 moves toward the upper end of the sleeve 212 with the external gear 211, thereby disengaging the external gear 211 from the operating gear 310. The state in which the external gear 211 is disengaged from the operating gear 310 is called the gear-out state.

[0048] Combination Figure 1 and Figure 6 As shown, the present invention has multiple clutch assemblies 21 arranged circumferentially, and the transmission assembly 11 of the control mechanism 1 is placed between the clutch assemblies 21. The transmission assembly 11 is provided with a transmission gear 110 that is simultaneously engaged with the controlled gears 213 of each clutch assembly 21. When the transmission gear 110 rotates, it can drive all the controlled gears 213 engaged therewith to rotate, so that the clutch assembly 21 drives the external gear 211 disposed at the end of the clutch assembly 21 to rotate. The transmission assembly 11 is connected to the first motor 112, and is controlled by the first motor 112 to provide a first torque.

[0049] Combination Figure 1 and Figure 7 As shown, the switching assembly 12 of the control mechanism 1 includes a gear plate 120 and a wedge 121 arranged on the disk surface of the gear plate 120. In one embodiment, the wedge 121 is a component with a pointed cross section, whose cross section is perpendicular to the disk surface of the gear plate 120 and the top rib formed at its tip coincides with a radius of the gear plate 120. The tip of the wedge 121 is arranged corresponding to the protruding end of the driving shaft 216 of each clutch assembly 21. Therefore, the wedge 121 is used to sequentially resist the driving shaft 216 of the self-locking rebounder of each clutch assembly 21 during the rotation of the gear plate 120. The gear plate 120 is coaxially arranged with the transmission assembly 11. The gear plate 120 is connected to the second motor 122 through the driving gear 123, and the second motor 122 provides a second torque for the gear plate 120 to drive the wedge 121 to do circular motion. The wedge-shaped member 121 protrudes from the surface of the gear plate 120 . As the gear plate 120 performs a circular motion, the wedge-shaped member 121 exerts a driving force on the driving shaft 216 of the self-locking rebounder 210 of each clutch assembly 21 passing through the wedge-shaped member 121 in the protruding direction of the wedge-shaped member 121 .

[0050] In short, the push shaft 216 is acted upon by the second torque of the switching component 12 to push the steering shaft 215 to compress the elastic component 214, so that the steering shaft 215 in the open state is disengaged from the slideway 2120 at the end of the compression stroke and rotates back to enter the self-locking state, or the steering shaft 215 in the self-locking state is released from the self-locking state and rotates back to the open state. In addition, the switching component 12 controls the same clutch component 21 odd times, causing the clutch component 21 to be engaged, and the switching component 12 controls the same clutch component 21 even times, causing the clutch component 21 to be disengaged; or, the switching component 12 controls the same clutch component 21 even times, causing the clutch component 21 to be engaged, and the switching component 12 controls the same clutch component 21 odd times, causing the clutch component 21 to be disengaged.

[0051] The linkage relationship among the control mechanism 1 , the shift mechanism 2 and the actuator 3 will be further described below through an operation example.

[0052] The state in which the controlled gears 213 of all clutch components 21 of the shift mechanism 2 of the antenna controller are separated from the operating gear 310 of the actuator 31 is set as the initial state, that is, all clutch components 21 are in the open state. Suppose a phase shift operation needs to be performed on a target actuator 31A among the multiple actuators 31.

[0053] The second motor 122 is driven, and the second motor 122 outputs a second torque, so that the driving gear 123 drives the gear plate 120, and the wedge 121 rotates with the gear plate 120 to the position of the clutch assembly 21 corresponding to the target execution assembly 31A, and the wedge 121 contacts the exposed portion 2161 of the driving shaft 216 of the clutch assembly 21, giving the driving shaft 216 a forward driving force, so that the clutch assembly 21 changes from an open state to a self-locking state, and stops driving the second motor 122. When the clutch assembly 21 is in the self-locking state, its corresponding external gear 211 meshes with the operating gear 310 of the target execution assembly 31A, that is, the gear is engaged.

[0054] The first motor 112 is driven to output the first torque, so that the transmission assembly 11 rotates, and then the transmission gear 110 of the transmission assembly 11 rotates. Since the transmission gear 110 is meshed with the controlled gear 213 of the clutch assembly 21, the transmission gear 110 can drive the clutch assembly 21 to rotate through the controlled gear 213, and then the external gear 211 of the clutch assembly 21 rotates. The external gear 211 further drives the operating gear 310 of the target execution assembly 31A, and the rotation of the operating gear 310 drives the screw 3111 fixedly connected thereto, so that the nut 3112 screwed with the screw 3111 moves along the axial direction of the screw 3111. The direction in which the screw 3111 needs to move determines the direction in which the first motor 112 outputs the first torque. Different directions make the transmission gear 110 rotate in different directions to meet the needs of phase adjustment with the external phase shifter of the screw 3111. After the phase adjustment operation of the target execution assembly 31A is completed, the driving of the first motor 112 is stopped.

[0055] The second motor 122 is driven again, so that the wedge 121 rotates with the gear plate 120 to contact the exposed portion 2161 of the clutch assembly 21 corresponding to the target actuator 31A to push the shaft 216, so that the clutch assembly 21 changes from the self-locking state to the open state, so that the clutch assembly 21 is disengaged.

[0056] If the antennas of other frequency bands are to be phased, the second motor 122 is driven again to make the wedge-shaped member 121 rotate with the gear plate 120 to contact the clutch assembly 21 corresponding to other target execution assembly 31 again, and the above operation is repeated.

[0057] The antenna controller can simultaneously place multiple adjacent clutch components 21 in a self-locking state before performing a phase adjustment operation, or can place only one clutch component 21 in a self-locking state before performing a phase adjustment operation. That is, the antenna controller provided by the present invention can simultaneously perform a phase shift operation on phase shifters of multiple frequency bands, or can perform a phase shift operation on a single phase shifter of a frequency band.

[0058] The antenna controller provided by the present invention selects any one or more connected clutch components 21 of the shift mechanism 2 to be adjusted to a self-locking state through a control mechanism 1 to select an actuator component 31 of an actuator 3 corresponding to the frequency band to be phase-adjusted; and then the selected actuator component 31 is phase-adjusted through the control mechanism 1. After the phase-adjustment operation is completed, the corresponding clutch component 21 is adjusted to an open state. The antenna controller provided by the present invention has a simple structure, is easy to operate, can quickly change direction and realize high-precision transmission. In addition, the transmission cost can be simplified, the stability is high, and the cost of the antenna controller is reduced.

[0059] The present invention also provides an antenna, comprising radiating arrays corresponding to multiple frequency bands, each radiating array being provided with a phase shifting component for changing the phase of the output signal of the antenna, and also comprising the above-mentioned antenna controller, which is used to simultaneously couple multiple phase shifting components therein to implement synchronous phase shift control of any number of the phase shifting components therein, thereby realizing synchronous phase shift control of multiple radiating arrays corresponding to different frequency bands using a single antenna controller.

[0060] The above description is only a preferred embodiment of the present invention and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present invention is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
