Detailed Description

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings illustrate, by way of example, specific embodiments in which the invention may be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments according to the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

The technical problem of the prior art is that the transmission structure of the prior art exists in the lateral direction of the phase shifter, which on the one hand makes the transmission structure inevitably interfere with the cable which is also in the lateral direction of the phase shifter, and on the other hand, has a great adverse effect on the wind load performance of the antenna.

To the technical problem above, the utility model provides a novel move looks ware, this move looks ware in transmission's at least partly not arranged at the side direction ascending that moves looks ware. Instead, according to the present invention, at least a part of the transmission means of the phase shifter is arranged above the top of the phase shifter, so that it does not occupy the lateral width of the phase shifter, does not interfere with the cable and does not increase the wind load of the phase shifter and the antenna comprising the phase shifter.

Particularly, the utility model provides a novel transmission structure that is used for looks ware that moves of basic station antenna can solve at least one in the following problem:

first, the front and back movement of the end pull rod of the conventional solution requires space relative to the conventional translation solution, thereby affecting the structural layout.

Secondly, compared with the traditional rotating scheme, the traditional scheme has the problems of difficult layout caused by arranging a transmission mechanism on the side edge of the cavity, or the problems of increased cost and weight and reduced wind load performance caused by increasing the width.

Furthermore, the foundation the utility model discloses a solution can also be solved because the accumulative total error that the drive mechanism cooperation was too much leaded to easily causes the poor problem of transmission synchronism and the wearing and tearing problem between moving part and the cavity.

According to the technical scheme of the utility model not only can apply to in conventional antenna, also can apply to in the multiple-input multiple-output antenna of Massive MIMO.

In summary, in order to solve at least one of the above technical problems, the present invention provides a phase shifter, comprising: at least two dielectric slabs, wherein at least one of the at least two dielectric slabs is provided with a rack; at least one circuit board disposed between the at least two dielectric boards; a first rotating member including a drive gear, wherein the drive gear is configured in a stacking direction of the at least two medium plates; and a second rotating member having an axis perpendicular to an axis of the first rotating member, and including a first gear and a second gear, and wherein the first gear is configured to mesh with the driving gear, and the second gear is configured to mesh with the rack. Since the driving gear is arranged in the stacking direction of the at least two dielectric plates, in other words, the driving gear is arranged at the top end of the phase shifter instead of the side direction, the width of the phase shifter is greatly reduced, the volume of the phase shifter is reduced, and the wind load of the antenna comprising the phase shifter is reduced.

The phase shifter according to the present invention will be described in detail below with reference to fig. 1A, 1B, 2A, 2B, and 3, and the detailed structure and driving manner of the transmission device of the phase shifter according to the present invention will be described in detail. Wherein, fig. 1A shows an assembly schematic diagram of a phase shifter according to an embodiment of the present invention except for a housing, fig. 1B shows an assembly schematic diagram of the phase shifter shown in fig. 1A including a housing, fig. 2A shows a schematic diagram of a transmission of the phase shifter according to the embodiment of fig. 1A of the present invention, fig. 2B shows a schematic diagram of an assembled state of a first rotating member and a second rotating member of the phase shifter according to the embodiment of fig. 1A of the present invention, and fig. 3 shows an exploded view of a transmission 200 for a phase shifter according to another embodiment of the present invention.

In order to better illustrate the manner of transmission, the figures according to the invention mainly show the components necessary for transmission, while the figures other than fig. 1B omit components, such as phase shifter housings, which are not necessary for explaining the transmission principle.

As can be seen from fig. 1A, the phase shifter proposed by the present invention includes at least two dielectric plates, and in the embodiment shown in fig. 1A, four dielectric plates 130. Here, the first and third dielectric plates, as viewed from the left to the right, of the four dielectric plates 130 are configured with racks, while the second dielectric plate and the first dielectric plate are fixedly disposed relative to each other, and the fourth dielectric plate and the third dielectric plate are fixedly disposed relative to each other. Additionally or alternatively, it is also possible to form the second and fourth of the four dielectric plates 130, viewed from left to right, with a rack, while the first and second dielectric plates are arranged fixed relative to each other and the third and fourth dielectric plates are arranged fixed relative to each other. In addition, the phase shifter according to the present invention further includes at least one circuit board 140, two circuit boards 140 in the embodiment shown in fig. 1A. Here, each of the two circuit boards 140 is disposed between the corresponding two dielectric boards 130.

Since the driving gear is disposed in the stacking direction of the at least two dielectric plates 130, in other words, the driving gear is disposed at the top of the phase shifter rather than laterally, the width of the phase shifter is greatly reduced and thus the volume of the phase shifter is reduced, thereby reducing the wind load of the antenna including the phase shifter.

To further illustrate the location of the drive gear, fig. 1B illustrates an assembly schematic of the phase shifter illustrated in fig. 1A including a housing 160. As can be seen in fig. 1B, the drive gear 110 is disposed at the top of the phase shifter housing 160, rather than laterally. In addition, it can be seen from fig. 1B that the drive gear 110 can be connected to a universal joint 112, for example by means of a transmission rod 111, and can be driven by means of the universal joint 112. The drive is not limited to a drive by means of a universal joint 112, but the drive rod 111 can be driven directly by a drive, such as an electric motor, or can be connected to the drive shaft via a universal joint 112 or can be driven indirectly by a drive rod connected to the drive. Further, fig. 1B shows a fixing part 150 and the first gear 121 of the second rotating member, the fixing part 150 for example fixes the driving gear 110 and the first gear 121 therein and makes the driving gear 110 and the first gear 121 mesh so as to realize driving of the second gear 122 and the dielectric sheet 130, so that the dielectric sheet 130 can move relative to the circuit board between two layers of the dielectric sheet 130, thereby realizing a desired phase shift effect.

In other words, as can be seen from fig. 1B, in the embodiment shown in fig. 1B, the first gear 121 is located outside the cavity formed by the housing 160 of the phase shifter, i.e. the first gear 121 is arranged at the top end of the cavity formed by the housing 160 of the phase shifter. The driving gear 110 is driven by the driving rod 111, and then the second rotating member is driven to drive the rack on the dielectric plate 130 to translate, so that the dielectric plate 130 can move relative to the circuit board 140 located between the two dielectric plates 130, thereby implementing the phase shifting operation of the phase shifter.

To further illustrate the transmission of the phase shifter according to the present invention, fig. 2A shows a schematic diagram of the transmission of the phase shifter according to the embodiment of fig. 1A of the present invention. As can be seen in fig. 2A, the transmission comprises at least a first and a second rotating member. Wherein the first rotating member includes a driving gear 110 and the second rotating member includes a first gear 121 and a second gear 122. The axis of the second rotating member is perpendicular to the axis of the first rotating member. The first gear 121 is configured to mesh with the driving gear 110, and the second gear 122 is configured to mesh with a rack gear configured on a medium plate 130 of a phase shifter.

That is, the first gear 121 does not extend beyond the side of the phaser housing 160, but rather lies entirely on the top of the phaser housing 160. Preferably, in the transmission device shown in fig. 2A according to the present invention, since the projection of the first gear 121 along the axis of the second rotating member is located in the phase shifter and the second gear 122 is located in the cavity of the phase shifter, and the first gear 121 is configured to engage with the driving gear and the second gear 122 is configured to engage with the rack configured on the dielectric plate 130 of the phase shifter, the transmission device according to the present invention is not disposed laterally of the phase shifter but disposed on the top of the phase shifter, thereby reducing the volume of the phase shifter and further reducing the wind load of the antenna including the phase shifter.

Furthermore, as can be seen from fig. 2A, a notch is provided on the circuit board 140 of the cavity of the phase shifter to accommodate at least a portion of the second rotating member, so that at least a portion of the second rotating member (for example, the second gear 122) can be meshed with the rack on the dielectric plate 130 of the phase shifter, so that the second rotating member driven by the first rotating member 110 is driven, and finally, the translation of the dielectric plate 130 of the phase shifter is realized, so that the dielectric plate 130 can move relative to the circuit board located between the two dielectric plates 130, so as to realize the phase shifting operation of the phase shifter. The printed circuit board 140 can be, for example, a printed circuit board, which can be a component of a phase shifter.

As shown in fig. 2A, it employs worm bevel gear commutation. Specifically, the transmission in fig. 1 includes a first rotating member 110 and a second rotating member. Wherein the first rotating member 110 includes a driving gear (e.g., a right-side threaded portion of the first rotating member 110 in fig. 1), and the second rotating member includes a first gear 121 and a second gear 122. The axis of the second rotating member is perpendicular to the axis of the first rotating member, that is, the longitudinal axis of the second rotating member is perpendicular to the longitudinal axis of the first rotating member, so as to facilitate the transmission. The first gear 121 is configured to mesh with the drive gear, and the second gear 122 is configured to mesh with a rack gear configured on a medium plate 130 of a phase shifter. Preferably, in the assembled state, the projection of the first gear 121 along the axis of the second rotating member is located in the phaser and the second gear 122 is located within the chamber of the phaser. That is, the first gear 121, whether mounted inside or outside the phaser cavity, is not mounted in a lateral orientation of the phaser cavity, but rather is mounted inside or on top of the phaser cavity. In the transmission device of the phase shifter according to the present invention, since the projection of the first gear 121 along the axis of the second rotating member is located in the phase shifter and the second gear 122 is located in the cavity formed by the housing 160 of the phase shifter, and the first gear 121 is configured to engage with the driving gear 110 and the second gear 122 is configured to engage with the rack formed on the dielectric plate 130 of the phase shifter, the transmission device of the phase shifter according to the present invention is not disposed in the lateral direction of the phase shifter but disposed at the top of the phase shifter, thereby further reducing the volume of the phase shifter and further reducing the wind load of the antenna including the phase shifter.

Preferably, in the assembled state, the first gear 121 is located outside the cavity of the phaser and the second gear 122 is located inside the cavity of the phaser. In the transmission device of the phase shifter according to the present invention, since the first gear 121 is located outside the cavity of the phase shifter and the second gear 122 is located inside the cavity formed by the housing 160 of the phase shifter, and the first gear 121 is configured to engage with the driving gear 110 and the second gear 122 is configured to engage with the rack configured on the dielectric plate 130 of the phase shifter, at least most of the transmission device of the phase shifter according to the present invention is not disposed in the lateral direction of the phase shifter but disposed at the top of the phase shifter, thereby reducing the volume of the phase shifter and further reducing the wind load of the antenna including the phase shifter. Alternatively, the transmission device may further include a rack bar formed on a sidewall of the dielectric plate 130 of the phase shifter.

Further, in the example shown in fig. 2A, in one embodiment according to the present invention, the engagement between the driving gear 110 and the first gear 121 is configured as a worm and helical gear engagement. Preferably, in an embodiment according to the present invention, the first gear 121 is configured as a helical gear and the second gear 122 is configured as a spur gear. The first rotation member 110 can be realized here using a worm, the second rotation member comprising two parts, wherein the first gear wheel 121 can be, for example, a helical gear wheel, so as to mesh with the first rotation member 110 configured as a worm, and the second gear wheel 122 comprises, for example, a toothed section, which can be either straight or helical. In comparison, the second gear 122 is easily formed by using straight teeth. The second gear 122 drives the first translational member, such as the rack of the medium plate 130, to move horizontally. The rack structure is disposed on a sidewall of the dielectric slab.

To illustrate the assembly fit of these transmission members, fig. 2B shows a schematic view of the assembled state of the transmission for the phase shifter according to the embodiment of fig. 1A of the present invention.

The driving gear 110 of the first rotating member is disposed in the fixing part 150, and the limit is realized by the fixing part 150, and the first rotating member has a mechanical interface, such as a socket head, outward, so that the driving rod 111 (shown in fig. 1B) as a driving rod can be inserted into the mechanical interface of the socket head, thereby driving the driving gear to rotate. Here, the fixing member 150 is provided with a hole to be engaged with a rotation shaft of the driving gear 110 of the first rotation member. Meanwhile, the fixing part 150 has a stopper surface on the other surface opposite to the hole through which the rotation shaft of the driving gear 110 for the first rotation member passes, for example, another stopper hole is provided on the other opposite surface, and the stopper hole is engaged with the fixing part 150, so that a certain axial position of the driving gear 110 for the first rotation member, that is, another axial position is realized by the other fixing part or stopper surface. Similarly, the second rotating member may be disposed in the fixed part 150, so that the second rotating member has only rotational freedom. But also ensures that the first gear 121 can be properly engaged with the driving gear 110.

Further preferably, in order to improve the wear resistance, another fixing member may be provided between the shaft 124 and the hole of the cavity wall, and a shoulder 123 between the first gear 121 and the second gear 122 and an upper wall of the phase shifter housing 160 to improve the wear resistance, and this embodiment integrates this function on the fixing member 150, such as the holding portion 151. At this time, the shoulder 123 is fixed by means of the holding portion 151, which ensures reliability of the fixing on the one hand and also reduces wear of the second rotating member on the other hand, thereby improving the service life of the second rotating member. In addition, the second gear 122 of the lower portion of the second rotation member or the upper portion of the first translational part (e.g., rack) may be provided with a guide structure so that the second rotation member is easily assembled when inserted into the interior of the cavity of the phase shifter to engage with the first translational part.
