Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a phase shifting component. Background Art

[0002] There are a large number of base stations in mobile communication systems. Each base station includes one or more base station antennas. The base station antenna typically includes multiple radiating elements (also referred to as antenna elements). Due to the need for coverage or optimization of the mobile communication network, the elevation pointing direction of the antenna beam generated by the base station antenna should be adjustable (for example, this can be achieved by a phase shifter in the base station antenna). The antenna phase shifter can be used to adjust the phase of the components of the radio frequency signal transmitted or received by the array of antenna elements. By changing the phase distribution of the components of the radio frequency signal transmitted or received by the individual antenna elements of the array antenna, the downtilt angle of the antenna beam can be adjusted.

[0003] In existing electrically adjustable base station antennas, the transmission device for the antenna phase shifter is an important component, which plays a very important role in the structure and reliability of the product and also accounts for a considerable proportion of the product cost.

[0004] Existing transmissions typically use translational input power to drive the antenna phase shifter. This translatory component in the transmission takes up a lot of space, leading to insufficient antenna space. Furthermore, transmissions typically include a translational adapter, and manufacturing and assembly tolerances of this adapter can lead to cumulative output errors. Summary of the Invention

The accompanying drawings illustrate, by way of example, specific embodiments that can implement the present invention. The illustrative embodiments are not intended to be exhaustive of all embodiments according to the present invention. It will be understood that other embodiments may be utilized, and structural or logical modifications may be made, without departing from the scope of the present invention. Therefore, the following detailed description is not restrictive, and the scope of the present invention is defined by the appended claims.

[0070] As used herein, the terms "including," "comprising," and similar terms should be understood as open-ended terms, i.e., "including but not limited to," indicating that other contents may also be included. The term "based on" means "based, at least in part, on." The term "one embodiment" means "at least one embodiment," and the term "another embodiment" means "at least one additional embodiment," and so on.

[0071] The technical problem to be solved by the present invention is how to reduce the volume of the phase shifting assembly, improve the transmission accuracy in the phase shifting assembly, and reduce the manufacturing cost of the phase shifting assembly.

[0072] In order to solve the above-mentioned technical problems, the phase shifting assembly disclosed in this article includes: an antenna phase shifter and a driving device. Specifically, the antenna phase shifter includes at least one first phase-shifting fixed unit, at least one first phase-shifting movable unit, and at least one first phase-shifting rotating mechanism. The driving device includes: a power mechanism for providing driving force for the antenna phase shifter, a first rotating component connected to the power mechanism and coupled to at least one first phase-shifting rotating mechanism, and a limiter for limiting the movement of the first phase-shifting rotating mechanism in its axial direction. The first rotating component transmits the driving force of the power mechanism to the first phase-shifting rotating mechanism via the first rotating component to control the relative movement of the first phase-shifting fixed unit and the first phase-shifting movable unit.

[0073] Example 1

[0074] like Figure 1 、 Figure 2a as well as Figure 2bAs shown, an example of a phase shifting assembly of the present disclosure is disclosed. In this example, the phase shifting assembly includes: an antenna phase shifter and a driving device. In this embodiment, the antenna phase shifter includes a pair of first phase shifting rotating mechanisms 21, a pair of first phase shifting movable units 22, and a pair of first phase shifting fixed units 23 arranged in the same plane; wherein the pair of first phase shifting fixed units 23 are both mounted on the housing 20 of the antenna phase shifter, and the pair of first phase shifting movable units 22 are respectively mounted on the corresponding first phase shifting rotating mechanisms 21. In addition, the first phase shifting movable unit 22 is provided with a first movable phase shifting trace 221, and the first phase shifting fixed unit 23 is provided with a first fixed phase shifting trace 231. The driving device includes: a power mechanism (not shown in the figure) for providing driving force for the antenna phase shifter, a first rotating component 10 connected to the power mechanism, and a limiter 30.

[0075] Specifically, the first rotating component 10 is coupled to at least one first phase-shifting rotating mechanism 21, so that the first rotating component 10 transmits the driving force of the power mechanism to the first phase-shifting rotating mechanism 21 to drive the first phase-shifting rotating mechanism 21 to move. At the same time, the movement of the first phase-shifting rotating mechanism 21 controls the first phase-shifting movable unit 22 to rotate relative to the first phase-shifting fixed unit 23, so that the contact position between the first movable phase-shifting trace 221 of the first phase-shifting movable unit 22 and the first fixed phase-shifting trace 231 of the first phase-shifting fixed unit 23 changes, thereby changing the phase of the external output signal.

[0076] In addition, in actual use, the first phase-shifting rotating mechanism 21 and the corresponding first phase-shifting movable unit 22 may also be integrally formed.

[0077] In this embodiment, a portion of the first phase-shifting rotation mechanism 21 and the first portion 11 of the first rotating component 10 are coupled and disposed within a position-limiting portion 30. When the power mechanism drives the first rotating component 10 to rotate, the position-limiting portion 30 limits the axial movement of the first phase-shifting rotation mechanism 21 and simultaneously limits the axial position of the first portion 11 of the first rotating component 10, thereby ensuring that the first portion 11 of the first rotating component 10 stably drives the first phase-shifting rotation mechanism 21 to move.

[0078] like Figure 1 and Figure 2a As shown, in this embodiment, the first rotating component 10 is arranged between the two first phase-shifting rotating mechanisms 21 and is coupled to the two respectively, and a portion of each first phase-shifting rotating mechanism 21 and the first portion 11 of the first rotating component 10 are arranged in the limiting portion 30.

[0079] In this embodiment, the first portion 11 of the first rotating member 10 is a worm structure, and the edge of the first phase-shifting rotating mechanism 21 is provided with teeth, so that the first portion 11 of the first rotating member 10 meshes with the teeth of the first phase-shifting rotating mechanism 21 .

[0080] Specifically, the teeth of the first phase-shifting rotating mechanism 21 can be helical gears, thereby implementing a worm-helical gear transmission between the first rotating component 10 and the first phase-shifting rotating mechanism 21. When the worm drives the first phase-shifting rotating mechanism 21 to rotate, the teeth of the first phase-shifting rotating mechanism 21 are subjected to a lateral force. This lateral force is directed toward the housing 20 of the antenna phase shifter, or toward the side of the first phase-shifting rotating mechanism 21 facing away from the housing 20. When this lateral force is directed toward the side of the first phase-shifting rotating mechanism 21 facing away from the housing 20, the first phase-shifting rotating mechanism 21 may be pulled away from the housing 20 under the action of this lateral force, resulting in poor contact between the first phase-shifting movable unit 22 and the first phase-shifting fixed unit 23. The provision of a limiter 30 to offset this lateral force effectively ensures reliable contact between the first phase-shifting movable unit 22 and the first phase-shifting fixed unit 23.

[0081] In this embodiment, although a portion of the first phase-shifting rotation mechanism 21 and the first portion 11 of the first rotating component 10 are disposed within the limiting portion 30, it is understood that the first portion 11 of the first rotating component 10 does not necessarily need to be disposed within the limiting portion 30. Preferably, a portion of the first phase-shifting rotation mechanism 21 and the first portion 11 of the first rotating component 10 are disposed within the limiting portion 30. In this case, the limiting portion 30 can not only offset the lateral force exerted on the first phase-shifting rotation mechanism 21, but also support the first rotating component 10, thereby saving material and space.

[0082] Furthermore, the first portion 11 of the first rotating component 10 may be an even-start worm or a single-start worm.

[0083] When the first part 11 of the first rotating component 10 is an even-numbered worm gear, the two first phase-shifting rotating mechanisms 21 in the same plane can be symmetrically arranged, so that the first part 11 of the first rotating component 10 is respectively engaged with the teeth of the two first phase-shifting rotating mechanisms 21, ensuring that the two first phase-shifting rotating mechanisms 21 rotate simultaneously.

[0084] When the first part 11 of the first rotating component 10 is an odd-head worm, the teeth of the two first phase-shifting rotating mechanisms 21 in the same plane are offset from each other by n+1 / 2 tooth pitches (where n=0, 1, 2...), so that the first part 11 of the first rotating component 10 is respectively engaged with the teeth of the two first phase-shifting rotating mechanisms 21, ensuring that the two first phase-shifting rotating mechanisms 21 rotate synchronously.

[0085] In this embodiment, when the power mechanism drives the first rotating component 10 to rotate, the first portion 11 (e.g., a worm structure) engages with the teeth of the first phase-shifting rotating mechanism 21, thereby driving the first phase-shifting rotating mechanism 21 to rotate around its center to control the relative movement of the first fixed phase-shifting trace 231 and the first movable phase-shifting trace 221, thereby achieving phase adjustment of the antenna phase shifter.

[0086] In this embodiment, when the first portion 11 of the first rotating member 10 rotates clockwise, the pair of first phase-shifting rotating mechanisms 21 engaged therewith rotate around their centers respectively, and the rotation directions of the pair of first phase-shifting rotating mechanisms 21 are opposite, but the linear speeds of the two rotations are the same.

[0087] In the technical solution disclosed herein, a worm-helical gear transmission is used to drive the antenna phase shifter. Because the worm's tooth flanks are also helical, axial forces are exerted on both the first phase-shifting rotation mechanism 21 and the first portion 11 of the first rotating component 10. To maintain the axial position of the first phase-shifting rotation mechanism 21, eliminate axial forces exerted on the first phase-shifting rotation mechanism 21, ensure transmission accuracy, and secure the first portion 11 of the first rotating component 10, the disclosed position-limiting member 30 can be utilized.

[0088] like Figure 3a and Figure 3b As shown, in this embodiment, the limiting portion includes a first limiting structure 31 and a second limiting structure 32 disposed below the first limiting structure 31. Specifically, the first limiting structure 31 includes a first end 311 and a second end 314 that are parallel to each other, and a sidewall 312 that is perpendicular to the first end 311 and the second end 314. The first portion 11 of the first rotating component 10 is disposed within the first limiting structure 31, and a portion of the first phase-shifting rotation mechanism 21 is disposed between the first limiting structure 31 and the second limiting structure 32, such that the first portion 11 of the first rotating component 10 engages with a portion of the first phase-shifting rotation mechanism 21.

[0089] In this embodiment, a first mounting hole 3111 is defined at the first end 311 of the first limiting structure 31 , and the first portion 11 of the first rotating component 10 is fixed in the first limiting structure 31 through the first mounting hole 3111 .

[0090] Alternatively, the first end 311 of the first limiting structure 31 is provided with a first mounting hole 3111, and the second end 314 is provided with a second mounting hole (not shown in the figure), and the first part 11 of the first rotating component 10 is fixed in the first limiting structure 31 through the first mounting hole 3111 and the second mounting hole.

[0091] The two side ends 3123 of the side wall 312 are respectively provided with an arcuate groove 3121, and a protrusion 313 is provided at the bottom of each arcuate groove 3121. Each protrusion 313 is parallel to and opposite to the second limiting structure 32, so that a portion of the first phase-shifting rotation mechanism 21 is disposed between the pair of arcuate grooves 3121 and the second limiting structure 32 by means of the pair of protrusions 313.

[0092] Preferably, the sidewall 312 of the first limiting structure 31 further includes a hollow structure 3122. The hollow structure 3122 enhances the elasticity of the protrusion 313. This configuration allows the protrusion 313 to have a certain degree of elasticity, thereby accommodating manufacturing and assembly tolerances and facilitating assembly. Furthermore, the hollow structure 3122 can reduce the overall weight of the limiting portion.

[0093] In this embodiment, the curvature of each arcuate groove 3121 is related to the curvature of the sector-shaped first phase-shifting rotating mechanism 21 , so that the shapes of the arcuate groove 3121 and the first phase-shifting rotating mechanism 21 match each other to further improve the limiting effect of the limiting portion.

[0094] Thus, the axial position of a portion of the first phase shifting rotation mechanism 21 coupled (eg, engaged) with the first portion 11 of the first rotating member 10 is limited by means of the pair of protrusions 313 , the pair of arcuate grooves 3121 and the second limiting structure 32 .

[0095] The drive device and phase-shifting assembly disclosed in this embodiment utilize worm helical gears to achieve drive force reversal. Furthermore, the worm helical gear transmission achieves a large reduction ratio, increasing the output force of the antenna phase shifter. This also reduces the space occupied within the antenna during phase adjustment, simplifying the antenna's structural layout. Furthermore, a single rotating component simultaneously drives two phase-shifting rotating mechanisms, reducing overall antenna material costs and process complexity, thereby improving production efficiency.

[0096] Example 2

[0097] In this example, the antenna phase shifter is a multi-stage phase shifter (for example, the antenna phase shifter includes a plurality of phase shift fixed units, corresponding phase shift movable units, and corresponding phase shift rotating mechanisms, which are located in different planes and are arranged in parallel and spaced apart). Figure 4As shown, the two-stage antenna phase shifter includes a first phase-shifting rotating mechanism 21 and a second phase-shifting rotating mechanism 50, which are arranged in parallel and spaced apart on different planes, as well as a first phase-shifting fixed unit (not shown), a first phase-shifting movable unit (not shown) controlled by the first phase-shifting rotating mechanism 21, a second phase-shifting fixed unit (not shown), and a second phase-shifting movable unit (not shown) controlled by the second phase-shifting rotating mechanism 50. In this embodiment, the driving device further includes a second rotating component 40, a first transmission member 60, a second transmission member 70, and a second limiting portion (not shown).

[0098] In this embodiment, the second rotating component 40 is used to couple with the second phase-shifting rotating mechanism 50 to transmit the driving force of the power mechanism to the second phase-shifting rotating mechanism 50 to drive the second phase-shifting rotating mechanism 50 to move; the first transmission member 60 is connected to the first rotating component 10; the second transmission member 70 is coupled to the first transmission member 60 and connected to the corresponding second rotating component 40; the second limiting portion sets a part of the second phase-shifting rotating mechanism 50 therein.

[0099] In this embodiment, the first transmission member 60 and the second transmission member 70 are preferably gear members. When the power mechanism drives the first rotating member 10 to rotate, the power mechanism drives the second rotating member 40 to rotate through the coupled motion (e.g., meshing motion) of the first transmission member 60 and the second transmission member 70. The second limiting portion limits the axial motion of the corresponding second phase-shifting rotation mechanism 50 and limits the axial position of the first portion 41 of the second rotating member 40, thereby ensuring that the first portion 41 of the second rotating member 40 drives the corresponding second phase-shifting rotation mechanism 50 to move.

[0100] In this embodiment, the first portion 41 of the second rotating component 40 may be a worm structure, and the edge of the second phase-shifting rotating mechanism 50 is provided with teeth, so that the first portion 41 of the second rotating component 40 meshes with the teeth of the second phase-shifting rotating mechanism 50 .

[0101] In this embodiment, the structure and function of the second limiting portion are the same as or similar to the structure and function of the limiting portion 30 in the previous embodiment, and are not described in detail here.

[0102] In addition, the phase shift assembly disclosed in this example may include two or more second phase-shifting fixed units, corresponding second phase-shifting movable units, and second phase-shifting rotating mechanisms located in different planes; wherein the second phase-shifting fixed unit is provided with a second fixed phase-shifting trace, and the second phase-shifting movable unit is provided with a second movable phase-shifting trace. In this case, the power mechanism first drives the first rotating component 10 to rotate, and then the power mechanism controls the relative movement of the first phase-shifting fixed unit and the first phase-shifting movable unit and the relative movement of the corresponding second phase-shifting fixed unit and the second phase-shifting movable unit through the coupling movement of the first transmission member 60 and the second transmission member 70, and drives the relative movement of the corresponding second phase-shifting fixed unit and the second phase-shifting movable unit through the coupling movement of two adjacent second transmission members 70.

[0103] like Figure 5 As shown, when the antenna phase shifter includes two first phase shift rotation mechanisms 21 and two second phase shift rotation mechanisms 50 arranged in the same plane, the power mechanism can simultaneously drive the pair of first phase shift rotation mechanisms 21 to rotate via the first rotating component 10, and the power mechanism can also simultaneously drive the pair of second phase shift rotation mechanisms 50 to rotate in the same plane via the second rotating component 40.

[0104] Furthermore, in this example, when the first portion 11 of the first rotating member 10 and the first portion 41 of the second rotating member 40 are worm gears with an even number of starts, the teeth of the pair of first phase-shifting rotating mechanisms 21 are symmetrically arranged in the same plane, and the teeth of the pair of second phase-shifting rotating mechanisms 50 are symmetrically arranged in another plane. When the first portion 11 of the first rotating member 10 and the first portion 41 of the second rotating member 40 are worm gears with an odd number of starts, the teeth of the pair of first phase-shifting rotating mechanisms 21 are offset by n+1 / 2 tooth pitches (where n=0, 1, 2, etc.) and are arranged in the same plane, and the teeth of the pair of second phase-shifting rotating mechanisms 50 are offset by n+1 / 2 tooth pitches (where n=0, 1, 2, etc.) and are arranged in another plane.

[0105] In this example, in order to ensure that multiple phase shifting units in the same column rotate simultaneously and have the same rotational speed, the first portion 11 of the first rotating component 10 is a worm structure having a first spiral direction, and the first portion 41 of the second rotating component 40 adjacent to the first rotating component 10 is a worm structure having a spiral direction opposite to the first spiral direction; and when there are two or more phase shifting units in the same column, the first portions 41 of two adjacent second rotating components 40 have worm structures with opposite spiral directions.

[0106] The phase shift assembly disclosed in this example can utilize a power mechanism to drive multiple antenna phase shifters on the same side or in the same column to simultaneously achieve a phase shift function in the same direction, thereby improving phase shift efficiency and reducing manufacturing costs.

[0107] Example 3

[0108] like Figure 6 As shown, the phase shift component disclosed in this example is similar to Figure 4 The phase shift components shown in the figure are the same, so the same basic structure is not repeated here. The difference between the two is that Figure 6 In the disclosed phase shifting assembly, the drive device further includes a third transmission member 80 (preferably a gear in this embodiment), which is disposed as an idler gear between the first transmission member 60 and the second transmission member 70. The provision of the third transmission member 80 ensures that the first rotating component 10 and the corresponding second rotating component 40 rotate in the same direction.

[0109] Similarly, when the same column of the phase-shifting assembly includes two or more second rotating components 40 and multiple second phase-shifting rotating mechanisms 50, a third transmission member 80 is disposed between adjacent second transmission members 70. Thus, when the power mechanism drives the first rotating component 10 to rotate, the power mechanism drives the first phase-shifting rotating mechanism 21 and the corresponding second phase-shifting rotating mechanism 50 through the coupled motion of the first transmission member 60, the third transmission member 80, and the second transmission member 70. Simultaneously, the coupled motion of two adjacent second transmission members 70 and the third transmission member 80 therebetween causes the corresponding two second phase-shifting rotating mechanisms 50 to move.

[0110] like Figure 7 As shown, the phase shift component disclosed in this embodiment is similar to Figure 5 The phase shift components shown in the figure are the same, so the same basic structure is not repeated here. The difference between the two is that Figure 7 In the disclosed phase shifting assembly, the driving device also includes a third transmission member 80 (which can preferably be a gear in this embodiment), which is arranged as an idler wheel between the first transmission member 60 and the second transmission member 70, so that the rotation direction of the first rotating member 10 and the corresponding second rotating member 40 is the same.

[0111] In this example, since the first rotating component 10 and the one or more second rotating components 40 have the same rotation direction, the first portion of the rotating components having the same rotation direction can make the first phase-shifting rotating mechanism and the one or more second phase-shifting rotating mechanisms located on the same side have the same rotation direction.

[0112] The phase shift assembly disclosed in this example can utilize an idler wheel to achieve the phase shifting function of multiple antenna phase shifters on the same side or in the same column in the same direction, thereby improving the phase shifting efficiency and reducing the manufacturing cost.

[0113] Example 4

[0114] like Figure 8 、 Figure 9As shown, the phase shift assembly disclosed in this example includes: an antenna phase shifter and a driving device. Specifically, the antenna phase shifter includes a first phase-fixing unit, a first phase-moving movable unit, a first phase-rotating mechanism 21, a second phase-fixing unit, a second phase-moving movable unit, and a second phase-rotating mechanism 50; wherein, the first phase-fixing unit includes a first fixed phase-shifting trace (not shown in the figure), the first phase-moving movable unit includes a first movable phase-shifting trace (not shown in the figure), the second phase-fixing unit 53 includes a second fixed phase-shifting trace (not shown in the figure) and a matching hole 51, and the second phase-moving movable unit includes a second movable phase-shifting trace (not shown in the figure). The driving device includes: a power mechanism (not shown in the figure) for providing driving force for the antenna phase shifter, a first rotating component (not shown in the figure) connected to the power mechanism, a limiting portion, and a first driving element 24.

[0115] The limiting portion disclosed in this example includes a first limiting structure 31, which has the same structure and principle as the first limiting structure in the previous example and will not be further described here. Furthermore, in this example, the first phase-shifting rotation mechanism 21 and the second phase-shifting rotation mechanism 50 are mutually limited. The combination of the first limiting structure and the second limiting structure is sufficient to limit at least one of the first phase-shifting rotation mechanism 21 and the second phase-shifting rotation mechanism 50.

[0116] In this example, the first phase-shifting rotation mechanism 21 and the second phase-shifting rotation mechanism 50 can be fixed together by the mutual cooperation of a pair of first driving elements 24 and a pair of matching holes 51. When the first rotating component transmits the driving force of the power mechanism to the first phase-shifting rotation mechanism 21 to control the relative movement of the corresponding first phase-shifting fixed unit and the first phase-shifting movable unit, the first driving element 24 directly or indirectly drives the corresponding second phase-shifting rotation mechanism 50 to control the relative movement of the corresponding second phase-shifting fixed unit and the second phase-shifting movable unit.

[0117] In the case where the antenna phase shifter includes two or more second phase shift fixing units in the same column, a second driving element (not shown in the figure) is further provided at the bottom of the second phase shift fixing unit so that two adjacent second phase shift fixing units can be fixed together through the cooperation between the second driving element and the matching hole.

[0118] In the above case, when the first rotating component transmits the driving force of the power mechanism to the first phase-shifting rotating mechanism 21 to control the relative movement of the corresponding first phase-shifting fixed unit and the first phase-shifting movable unit, the first driving element 24 and the second driving element control the relative movement of the corresponding second phase-shifting fixed unit and the second phase-shifting movable unit by respectively driving the corresponding second phase-shifting rotating mechanism.

[0119] Alternatively, the first driving element 24 and the second driving element are integrally formed, so that at least one driving element drives multiple phase-shifting rotating mechanisms in the same column.

[0120] The phase-shifting assembly disclosed in this example utilizes the interplay between a rotating shaft and a mating hole to secure multiple phase-shifting rotation mechanisms in a row. The first phase-shifting rotation mechanism and the first rotating component, coupled within a stopper, ultimately enable the first rotating component to drive the phase shifting of multiple phase-shifting units. While achieving precise phase shifting, this solution also reduces installation space within the antenna and manufacturing costs.
