Description

Technical Field

[0001] This invention relates to the field of antenna communication technology, and in particular to an electrically adjustable antenna control device and an electrically adjustable antenna. Background Technology

[0002] With the increasing investment and optimization of my country's mobile communication infrastructure, electrically tunable antennas are being used more and more in the mobile communication field. Among them, the electrically tunable antenna controller is the most critical intelligent component of the antenna. In practical applications, the electrically tunable antenna controller can be used to adjust the electrical downtilt angle of the base station antenna. Currently, electrically tunable antenna controllers are generally installed using a mounting bracket and a mounting plate. The mounting bracket is used to fix the antenna controller, and the mounting plate is used to connect to the object to be connected. Specifically, the antenna controller is connected to the mounting bracket using screws or other fasteners, and the mounting bracket is connected to the mounting plate using screws or other fasteners. However, this results in a large number of components, making installation cumbersome. Furthermore, the metal contact caused by numerous fasteners can negatively impact antenna performance. Summary of the Invention

[0003] Therefore, it is necessary to provide an electrically adjustable antenna control device and an electrically adjustable antenna that are easy to install and can improve antenna performance.

[0004] The first aspect of this application provides an electrically adjustable antenna control device, comprising:

[0005] The mounting base has a bearing surface;

[0006] Two connectors are spaced apart along a first direction on the bearing surface of the mounting base; and

[0007] An electrically adjustable antenna control box is located between two connectors and is configured to be detachably connected to the connectors;

[0008] Two connectors are movably engaged with the mounting base, and the two connectors are configured to move towards or away from each other along a first direction, so as to switch between a disengaged position and an engaged position relative to the mounting base.

[0009] When the electrically adjustable antenna control box is located between the two connectors, the electrically adjustable antenna control box blocks the movement path of the two connectors moving towards each other in the first direction, so as to prevent the connectors from moving from the snap-fit ​​position to the disengaged position.

[0010] The mounting base engages with two connectors via a snap-fit ​​mechanism. When the electrically adjustable antenna control box is connected to the connectors, it blocks the path of the two connectors relative to the mounting base. Once installed, the electrically adjustable antenna control box self-locks the two connectors, preventing them from moving towards each other and detaching from the mounting base. Since the connectors only need to snap into the mounting base and be fixed to it via the electrically adjustable antenna control box, the connection between the connectors and the mounting base requires no external fasteners such as screws. This results in a simple and easy-to-install overall structure, and avoids the antenna performance degradation caused by metal fasteners.

[0011] In one embodiment, each connector includes a connector body and at least one snap-fit ​​arm connected to each other, and the mounting base is provided with at least two mounting holes penetrating the mounting base, and each snap-fit ​​arm of each connector is provided with a corresponding mounting hole.

[0012] Each snap-fit ​​arm passes through the corresponding mounting hole and snaps onto the surface of the mounting base that is away from the bearing surface.

[0013] This design makes the mounting base simpler in structure and easier to manufacture.

[0014] In one embodiment, each mounting hole includes a communicating clearance hole and a snap-fit ​​hole, and the snap-fit ​​arm is configured to pass through the clearance hole so that the corresponding connector is in a disengaged position;

[0015] The snap-fit ​​arm is configured to move along the clearance hole toward the snap-fit ​​hole and snap onto the edge of the snap-fit ​​hole so that the corresponding connector is in the snap-fit ​​position;

[0016] In the mounting holes corresponding to the snap-fit ​​arms of different connectors, the arrangement directions of the clearance holes and the snap-fit ​​holes are along the first direction and opposite to each other.

[0017] With this configuration, when the two connectors move in opposite directions, they can engage with the edge of the locking hole and be in the locking position. When the two connectors move towards each other, they can disengage from the locking hole and enter the clearance hole range, so that the connectors are in the disengaged position.

[0018] In one embodiment, the snap-fit ​​arm includes a snap-fit ​​arm body, a neck, and a snap-fit ​​end connected in sequence, with the snap-fit ​​arm body connected to the connector body;

[0019] The outer contour dimension of the snap-fit ​​end is smaller than the inner contour dimension of the clearance hole, but larger than the inner contour dimension of the snap-fit ​​hole; the outer contour dimension of the neck is smaller than both the inner contour dimensions of the clearance hole and the inner contour dimension of the snap-fit ​​hole; the outer contour dimension of the snap-fit ​​arm body is larger than both the inner contour dimensions of the clearance hole and the inner contour dimension of the snap-fit ​​hole.

[0020] When the connector is in the disengaged position, the neck and snap-fit ​​end can easily extend into or exit from the clearance hole. As the connector moves from the disengaged position to the snap-fit ​​position, the neck can enter the snap-fit ​​hole, and the snap-fit ​​end, driven by the neck, snaps into the side of the mounting base facing away from the bearing surface. At this time, the snap-fit ​​arm body also presses against the bearing surface, thereby snapping the snap-fit ​​arm onto the mounting base.

[0021] In one embodiment, the connector further includes a resilient arm, and at least one snap-fit ​​arm is provided with a resilient arm;

[0022] The bearing surface is provided with a limiting groove that corresponds to the elastic arm. The elastic arm is limited and engaged with the limiting groove, and the elastic arm is configured to always apply an elastic force toward the mounting base.

[0023] In this way, when the electrically adjustable antenna control box is not installed on the connector, the limiting cooperation between the elastic arm and the limiting groove can pre-fix the connector and prevent it from moving to the detached position.

[0024] In one embodiment, the elastic arm includes an elastic arm body and a limiting part, the limiting part being disposed on the surface of the elastic arm body facing the mounting seat and engaging in a limiting groove.

[0025] This allows for a simple and easy matching of the flexible arm and the mounting base.

[0026] In one embodiment, the electrically adjustable antenna control box is guided and engaged with two connectors along a second direction;

[0027] The second direction is perpendicular to the first direction.

[0028] This makes the locking effect of the electrically adjustable antenna control box on the two second connectors better.

[0029] In one embodiment, one of the facing surfaces of the electrically tunable antenna control box and the connector is provided with a guide rail groove, and the other is provided with a slider that guides and engages with the guide rail groove, the guide rail groove extending along a second direction.

[0030] In one embodiment, the electrically adjustable antenna control box is provided with a mounting post that extends toward the connector, and the connector also includes a hook that engages with the mounting post.

[0031] In this way, the pre-positioning of the electrically adjustable antenna control box and the two connectors can be achieved.

[0032] In one embodiment, the electrically adjustable antenna control device further includes a fastener that passes through the mounting post and is connected to the connector.

[0033] This allows for reliable positioning of the electrically adjustable antenna control box and connectors.

[0034] A second aspect of this application provides an electrically adjustable antenna, including the electrically adjustable antenna control device described above. Attached Figure Description

[0058] Reference Figure 1 , Figure 2 , Figure 3 The first aspect of this application provides an electrically adjustable antenna control device 100, including a mounting base 10, two connectors 20, and an electrically adjustable antenna control box 30.

[0059] Mounting base 10 has a bearing surface 12. Two connectors 20 are spaced apart along a first direction F on the bearing surface 12 of mounting base 10. An electrically adjustable antenna control box 30 is disposed between the two connectors 20 and configured to be detachably connected to the connectors 20. The two connectors 20 are movably engaged with mounting base 10 and configured to move towards or away from each other along the first direction F, switching between a disengaged position and an engaged position relative to mounting base 10. When the electrically adjustable antenna control box 30 is located between the two connectors 20, it blocks the movement path of the two connectors 20 along the first direction F, preventing the connectors 20 from moving from the engaged position to the disengaged position.

[0060] Two connectors 20 are movably engaged with the mounting base 10, and the two connectors 20 are configured to move towards or away from each other along a first direction F, switching between a disengaged position and an engaged position relative to the mounting base 10. When the electrically adjustable antenna control box 30 is connected between the two connectors 20, the electrically adjustable antenna control box 30 blocks the movement path of the two connectors 20 along the first direction F, preventing the connectors 20 from moving from the engaged position to the disengaged position. Thus, by movably engaging the mounting base 10 with the two connectors 20, and when the electrically adjustable antenna control box 30 is connected to the connectors 20, it blocks the disengagement path of the two connectors 20 relative to the mounting base 10. After the electrically adjustable antenna control box 30 is installed on the connectors 20, it can self-lock the two connectors 20, preventing the two connectors 20 from moving towards each other and disengaging from the mounting base 10. Since the connector 20 only needs to be snapped into the mounting base 10 and connected to the connector 20 via the electrically adjustable antenna control box 30, it can be relatively fixed to the mounting base 10. The connection operation between the connector 20 and the mounting base 10 does not require external fasteners such as screws. Not only is the overall structure simple and easy to install, but there will also be no decrease in antenna performance due to the use of metal fasteners.

[0061] In this embodiment, the mounting base 10 can be a structural component for mounting devices such as a transmission system, a phase shifter system, and an array radiating unit, for example, it can be a reflector. The bearing surface 12 of the mounting plate can be used to support and carry the connector 20, the electrically adjustable antenna control box 30, etc.

[0062] The electrically adjustable antenna control box 30 may include, for example, a box body and an electrically adjustable antenna control module (not shown) disposed within the box body. The detachable connection between the electrically adjustable antenna control box 30 and the connector 20 may be a screw connection or a plug-in engagement, etc.

[0063] The two connectors 20 are movably engaged with the mounting base 10, and are configured to move towards or away from each other along a first direction F, switching between a disengaged position and an engaged position relative to the mounting base 10. Specifically, when the two connectors 20 move away from each other relative to the mounting base 10 along the first direction F and engage with it, they are in the engaged position. Conversely, when the two connectors 20 move towards each other relative to the mounting base 10, they are no longer engaged and are in a movable, detachable state, in the disengaged position. It is understood that the disengaged position is not a fixed position but can be considered as the position of the connectors 20 in a non-engaged state relative to the mounting base 10, and can be within a certain range.

[0064] Additionally, the electrically adjustable antenna control box 30 is positioned along the moving path of the two connectors 20 as they move towards each other in the first direction F, preventing the connectors 20 from moving from the engaged position to the disengaged position. The electrically adjustable antenna control box 30 can abut against the opposing surfaces of the two connectors 20 to improve the self-locking effect, or it can maintain a certain distance from the opposing surfaces of the two connectors 20, as long as it does not cause the connectors 20 to move to the disengaged position.

[0065] In this embodiment of the application, combined with Figure 2 and Figure 8 Each connector 20 includes a connector body 21 connected to it and at least one snap-fit ​​arm 22. The mounting base 10 has at least two mounting holes 11 penetrating through it, and each snap-fit ​​arm 22 of each connector 20 has a corresponding mounting hole 11. Each snap-fit ​​arm 22 passes through its corresponding mounting hole 11 and snaps onto the surface of the mounting base 10 facing away from the bearing surface 12. This arrangement simplifies the structure of the mounting base 10 and facilitates its fabrication.

[0066] In this embodiment, each mounting hole 11 includes a communicating clearance hole 111 and a snap-fit ​​hole 112. The snap-fit ​​arm 22 is configured to pass through the clearance hole 111 so that the corresponding connector 20 is in a disengaged position. The snap-fit ​​arm 22 is configured to move along the clearance hole 111 toward the snap-fit ​​hole 112 and snap onto the edge of the opening of the snap-fit ​​hole 112 so that the corresponding connector 20 is in a snap-fit ​​position. This facilitates the switching of the connector 20 relative to the mounting base 10 between the snap-fit ​​position and the disengaged position.

[0067] like Figure 2 As shown, in the mounting holes 11 corresponding to the snap-fit ​​arms 22 of different connectors 20, the arrangement directions of the clearance holes 111 and the snap-fit ​​holes 112 are along the first direction F and opposite to each other. Figure 2In the middle, the two mounting holes 11 located on the upper left side of the drawing and located on the... Figure 2 As shown in the figure, there are two mounting holes 11 on the lower right side. In this way, when the two connectors 20 move in opposite directions at the same time, they can engage with the edge of the locking hole 112 and be in the locking position. When the two connectors 20 move towards each other at the same time, they can disengage from the locking hole 112 and enter the range of the clearance hole 111, so that the connectors 20 are in the disengaged position.

[0068] Furthermore, combined Figure 2 and Figure 5 The snap-fit ​​arm 22 includes a snap-fit ​​arm body 221, a neck 222, and a snap-fit ​​end 223 connected in sequence, with the snap-fit ​​arm body 221 connected to the connector body 21.

[0069] The outer contour dimension of the snap-fit ​​end 223 is smaller than the inner contour dimension of the clearance hole 111 and larger than the inner contour dimension of the snap-fit ​​hole 112. The outer contour dimension of the neck 222 is smaller than the inner contour dimensions of both the clearance hole 111 and the snap-fit ​​hole 112. The outer contour dimension of the snap-fit ​​arm body 221 is larger than the inner contour dimensions of both the clearance hole 111 and the snap-fit ​​hole 112.

[0070] With this configuration, when the connector 20 is in the disengaged position, the neck 222 and the snap-fit ​​end 223 can easily extend into or exit from the clearance hole 111. When the connector 20 moves from the disengaged position to the snap-fit ​​position, the neck 222 can enter the snap-fit ​​hole 112, and the snap-fit ​​end 223, driven by the neck 222, snaps onto the side surface of the mounting base 10 facing away from the bearing surface 12. At this time, the snap-fit ​​arm body 221 also presses against the bearing surface 12, thereby snapping the snap-fit ​​arm 22 onto the mounting base 10.

[0071] In this embodiment, the connector 20 may further include an elastic arm 23, with at least one snap-fit ​​arm 22 having an elastic arm 23. The bearing surface 12 has a limiting groove 121 corresponding to each elastic arm 23. The elastic arm 23 engages with the limiting groove 121, and the elastic arm 23 is configured to always apply an elastic force toward the mounting base 10. Thus, when the electrically adjustable antenna control box 30 is not installed on the connector 20, the limiting engagement of the elastic arm 23 with the limiting groove 121 can pre-fix the connector 20, preventing it from moving to a disengaged position.

[0072] Furthermore, the position of the limiting groove 121 corresponds to the snap-fit ​​hole 112. For example, when the connector 20 is in the snap-fit ​​position, the elastic arm 23 can be precisely matched with the limiting groove 121 to limit the connection, so that the connector 20 can be pre-positioned when it is in the snap-fit ​​position.

[0073] In a specific implementation, the elastic arm 23 includes an elastic arm body 231 and a limiting part 232. The limiting part 232 is disposed on the surface of the elastic arm body 231 facing the mounting base 10 and is engaged in the limiting groove 121. This allows for a simple limiting engagement between the elastic arm 23 and the mounting base 10.

[0074] In the embodiments of this application, reference is made to Figure 3 and Figure 4 The electrically adjustable antenna control box 30 and the two connectors 20 are guided and engaged along the second direction S, which is perpendicular to the first direction F. This improves the locking effect of the electrically adjustable antenna control box 30 on the two connectors 20. In this case, the engagement between the electrically adjustable antenna control box 30 and the two connectors 20 can also be considered a plug-in engagement.

[0075] In specific implementation, combined with Figure 3 and Figure 4 On the electrically adjustable antenna control box 30, one of the surfaces facing the connector 20 is provided with a guide rail groove 31, and the other is provided with a slider 32 that guides and engages with the guide rail groove 31. The guide rail groove 31 extends along the second direction S. For example, two protruding ribs 311 are provided on the side of the electrically adjustable antenna control box 30. The two protruding ribs 311 are spaced apart along the thickness direction of the electrically adjustable antenna control box 30, and the two protruding ribs 311 and the side of the electrically adjustable antenna control box 30 together define the aforementioned guide rail groove 31. The end of the connector 20 facing the guide rail groove 31 can form a slider 32 structure.

[0076] Furthermore, combined Figure 6 and Figure 7 The electrically adjustable antenna control box 30 is provided with a mounting post 40, which extends toward the connector 20. The connector 20 also includes a hook portion 24 that engages with the mounting post 40. In this way, when the electrically adjustable antenna control box 30 is inserted between the two connectors 20, the pre-positioning of the electrically adjustable antenna control box 30 and the two connectors 20 can be achieved.

[0077] Furthermore, the electrically adjustable antenna control device 100 also includes a fastener 50 that passes through the mounting post 40 and is connected to the connector 20. This ensures reliable positioning of the electrically adjustable antenna control box 30 and the connector 20.

[0078] The following is combined with Figure 2 Figure 3 The installation process of the electrically adjustable antenna control device 100 in this embodiment is explained.

[0079] The snap-fit ​​arms 22 of two different connectors 20 are installed into their corresponding mounting holes 11. During installation, the snap-fit ​​arms 22 of each connector 20 move into the snap-fit ​​position along the clearance hole 111 toward the snap-fit ​​hole 112. After entering the snap-fit ​​position, each elastic arm 23 also engages with the corresponding limiting groove 121, and the elastic arm 23 always applies an elastic force toward the mounting base 10. This pre-fixes the connectors 20, preventing them from moving out of the mounting position.

[0080] At this point, the guide rail groove 31 of the electrically adjustable antenna control box 30 is engaged with the slider 32 on the connector 20, that is, the electrically adjustable antenna control box 30 is inserted between the two connectors 20. At this time, the mounting post 40 is also engaged with the hook part 24. In this way, when the electrically adjustable antenna control box 30 is inserted between the two connectors 20 and fully inserted, the pre-positioning of the electrically adjustable antenna control box 30 and the two connectors 20 can be achieved. Finally, the fastener 50 is passed through the mounting post 40 and connected to the connector 20. This achieves reliable positioning of the electrically adjustable antenna control box 30 and the connector 20.

[0081] A second aspect of this application provides an electrically tunable antenna, including the aforementioned electrically tunable antenna control device. The structure, function, and working principle of the electrically tunable antenna control device have been described in detail above and will not be repeated here.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
