Technical Field

[0001] This utility model relates to the field of mechanical device technology, and in particular to an angle adjustment structure and antenna device. Background Technology

[0002] In the field of network communication, antennas are a crucial component. In specific applications, antennas are typically mounted outdoors on poles or communication towers using brackets. Azimuth and elevation angles are two important parameters for antenna installation. To ensure the antenna's radiation range, the azimuth and elevation angles need to be adjusted after the antenna is mounted on the appropriate pole or communication tower. Utility Model Content

[0003] This utility model provides an angle adjustment structure and an antenna device.

[0004] This utility model provides the following technical solution:

[0005] An angle adjustment structure includes:

[0006] Connecting seat, used to fix the angle adjustment structure to the carrier;

[0007] The first angle adjustment unit is configured to connect to the connecting seat and protrude from the connecting seat on the side of the connecting seat that is away from the carrier.

[0008] The second angle adjustment unit is configured to be connected to the end of the first angle adjustment unit that is away from the support body, and to be exposed on the side of the first angle adjustment unit that is away from the support body.

[0009] The mounting base is fixed to one end of the second angle adjustment unit that is away from the connecting base. The surface of the mounting base that is away from the connecting base is used to mount the external structure.

[0010] The first angle adjustment unit is used to drive the external structure to rotate around the first axis, and the second angle adjustment unit is used to drive the external structure to rotate around the second axis; wherein, the first axis is perpendicular to the second axis.

[0011] When the antenna device adopts this scheme, the azimuth angle is adjusted by rotating the antenna around a first axis through a first angle adjustment unit, and the elevation angle is adjusted by rotating the antenna around a second axis through a second angle adjustment unit. Based on the ability to adjust the azimuth and elevation angles of the antenna, the first angle adjustment unit protrudes from the connector on the side of the connector facing away from the carrier, and the second angle adjustment unit protrudes from the first angle adjustment unit on the side of the first angle adjustment unit facing away from the connector. The antenna is mounted on the surface of the mounting base facing away from the connector, thus making the overall angle adjustment structure larger in the direction facing away from the carrier. This, in turn, allows for a greater distance between the antenna mounted on the surface of the mounting base facing away from the second angle adjustment unit and the carrier, making it more suitable for larger antennas.

[0012] Optionally, the first angle adjustment unit includes a first support, a first active component, and a first driven component.

[0017] The axis of the first rotating shaft coincides with the first axis, the first actuating rod is located between the first rotating shaft and the first nut block, and the axis of the first actuating rod is parallel to the first axis. The first actuating rod is fixedly connected to the first rotating shaft through the first connecting arm 8.

[0018] The first nut block has a first long groove, the length direction of which is perpendicular to the first axis and the second axis; the first actuating rod is at least partially inserted in the first long groove, and the first actuating rod can slide in the first long groove along the length direction of the first long groove.

[0019] Optionally, the second angle adjustment unit includes:

[0020] The second support is configured to be detachably and fixedly connected to the first support, and the end of the second support facing away from the first support is connected to the mounting base;

[0021] The second active component is configured to be rotatably mounted on one end of the first support away from the connecting seat;

[0022] The second driven component is configured to be fixedly installed at one end of the second support near the first support and to be connected to the second driving component in a transmission manner;

[0023] After the first support and the second support are released from their fixed positions, the second driven component can rotate around the second axis under the drive of the second driving component.

[0024] Optionally, the second driving component includes a second worm gear, the axis of which is perpendicular to both the first axis and the second axis.

[0025] The second driven component includes a second worm gear, the axis of which coincides with the second axis.

[0026] The second worm gear meshes with the second worm wheel.

[0027] Optionally, the second active component includes a second screw, the axis of which is perpendicular to both the first axis and the second axis;

[0028] The second driven component includes a second nut block, a second rotating shaft, and a second actuating rod. The second nut block is sleeved on the second screw and threadedly connected to the second screw. The axis of the second rotating shaft coincides with the second axis. The second actuating rod is located between the second rotating shaft and the second nut block, and the axis of the second actuating rod is parallel to the axis of the second rotating shaft. The second actuating rod is fixedly connected to the second rotating shaft through a second connecting arm.

[0029] The second nut block is provided with a second long groove, the length direction of which is parallel to the first axis; the second actuating rod is at least partially inserted into the second long groove, and the second actuating rod can slide in the second long groove along the length direction of the second long groove.

[0030] Optionally, the mounting base and the end of the second support facing away from the first support are detachably fixedly connected, and an angle adjustment component is provided between the mounting base and the second support. The angle adjustment component is used to make the mounting base rotate relative to the second support about a third axis.

[0031] The third axis is parallel to the second axis.

[0033] This utility model also provides an antenna device, including an antenna and any of the angle adjustment structures provided in the above technical solutions. The antenna is installed on one end of the mounting base away from the second angle adjustment unit, and the first axis is used to be perpendicular to the horizontal plane.

[0034] In this design, the azimuth angle is adjusted by rotating the antenna around a first axis using a first angle adjustment unit, and the elevation angle is adjusted by rotating the antenna around a second axis using a second angle adjustment unit. Based on the ability to adjust both the azimuth and elevation angles, the first angle adjustment unit protrudes from the connector on the side of the connector facing away from the carrier, and the second angle adjustment unit protrudes from the first angle adjustment unit on the side of the first angle adjustment unit facing away from the connector. The antenna is mounted on the surface of the mounting base facing away from the connector, resulting in a larger overall size of the angle adjustment structure in the direction facing away from the carrier. This, in turn, increases the distance between the antenna mounted on the surface of the mounting base facing away from the second angle adjustment unit and the carrier, making it more suitable for larger antennas.

[0035] Optionally, the antenna device includes a column and at least one connecting component, each connecting component having at least two sets of locking components;

Detailed Implementation

[0047] In related technologies, antennas are fixed to poles or communication towers via angle adjustment structures. While these structures can adjust the azimuth and elevation angles of the antennas, when the antenna's outer dimensions are large (e.g., when the antenna is a large-aperture antenna), interference may occur between the antenna and the corresponding pole or communication tower, preventing the adjustment of the azimuth and elevation angles.

[0048] To facilitate understanding, the following will be combined with... Figure 1 The azimuth and elevation angles mentioned in this embodiment will be explained in detail below. Figure 1 In the diagram, line m represents the spatial position of the antenna at time T1, line n represents the spatial position of the antenna at time T2, dashed line m1 is the orthographic projection of line m in the XZ plane, dashed line m2 is the orthographic projection of line m in the XY plane, dashed line n1 is the orthographic projection of line n in the XZ plane, and dashed line n2 is the orthographic projection of line n in the XY plane. The angle between dashed line n1 and dashed line m1 is the elevation angle of the antenna, and the angle between dashed line n2 and dashed line m2 is the azimuth angle of the antenna.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0051] Figure 2 This is a schematic diagram of the angle adjustment structure provided in this embodiment when it is in an application scenario. Figure 3 for Figure 2 A schematic diagram of a local structure. (For example...) Figure 2 and Figure 3As shown, this embodiment provides an angle adjustment structure including a connecting base 2, a first angle adjustment unit 3, a second angle adjustment unit 4, and a mounting base 5. The connecting base 2 is used to fix the angle adjustment structure to a support (e.g., a column 100). The first angle adjustment unit 3 is configured to be connected to the connecting base 2 and protrude from the connecting base 2 on the side of the connecting base 2 facing away from the support. The second angle adjustment unit 4 is configured to be connected to the end of the first angle adjustment unit 3 facing away from the support and protrude from the first angle adjustment unit 3 on the side of the first angle adjustment unit 3 facing away from the support. The mounting base 5 is fixed to the end of the second angle adjustment unit 4 facing away from the connecting base 2, and the surface of the mounting base 5 facing away from the connecting base 2 is used to mount an external structure. The first angle adjustment unit 3 is used to drive the external structure to rotate around a first axis L1, and the second angle adjustment unit 4 is used to drive the external structure to rotate around a second axis L2. The first axis L1 is perpendicular to the second axis L2. Exemplarily, the external structure includes, but is not limited to, an antenna 200.

[0052] When the antenna device adopts this scheme, the azimuth angle is adjusted by rotating the antenna 200 around the first axis L1 through the first angle adjustment unit 3, and the elevation angle is adjusted by rotating the antenna 200 around the second axis L2 through the second angle adjustment unit 4. Based on the ability to adjust the azimuth and elevation angles of the antenna 200, the first angle adjustment unit 3 protrudes from the side of the connecting base 2 away from the carrier, and the second angle adjustment unit 4 protrudes from the side of the first angle adjustment unit 3 away from the connecting base 2. The antenna 200 is mounted on the surface of the mounting base 5 away from the connecting base 2, thus making the overall angle adjustment structure larger in the direction away from the carrier. This results in a larger distance between the antenna 200 mounted on the surface of the mounting base 5 away from the second angle adjustment unit 4 and the carrier, making it more suitable for larger antennas 200.

[0053] Figure 4 for Figure 3 An exploded view of the angle adjustment structure, where connecting component 1 is not shown. Please refer to... Figure 3 and Figure 4 In one possible implementation, the first angle adjustment unit 3 includes a first support 31, a first active component, and a first driven component. The first support 31 is detachably fixed to the connecting seat 2. The first active component is rotatably disposed on the connecting seat 2. The first driven component is fixedly disposed on the first support 31 and is connected to the first active component in a transmission manner. After the first support 31 is released from the connecting seat 2, the first driven component can rotate around the first axis under the drive of the first active component.

[0054] In one specific implementation, the first active component includes a first worm gear 32, which is rotatably mounted on the connecting seat 2, and the axis of the first worm gear 32 is parallel to the second axis L2. The first driven component includes a first worm wheel 33, the axis of which coincides with the first axis L1, and the first worm gear 32 is meshed with the first worm wheel 33. The first worm gear 32 and the first worm wheel 33 can work together to achieve fine adjustment of the azimuth angle of the mounting seat 5 and the antenna 200 mounted on the mounting seat 5, and the worm gear transmission structure has fewer components and is easier to install.

[0055] like Figure 5 As shown, as an alternative, the first driving component includes a first screw 34, which is rotatably mounted on the connecting seat 2, and the axis of the first screw 34 is parallel to the second axis L2. The first driven component includes a first nut block 35, a first rotating shaft 36, and a first actuating rod 37. The first nut block 35 is sleeved on the first screw 34 and threadedly connected to the first screw 34; the first rotating shaft 36 is rotatably mounted on the first support 31, and the axis of the first rotating shaft 36 coincides with the first axis L1. The first actuating lever 37 is located between the first rotating shaft 36 and the first nut block 35, and the axis of the first actuating lever 37 is parallel to the first axis L1. The first actuating lever 37 is fixedly connected to the first rotating shaft 36 through the first connecting arm 38. The first nut block 35 is provided with a first elongated groove 351, the length direction of which is perpendicular to the first axis L1 and the second axis L2. The first actuating lever 37 is at least partially inserted into the first elongated groove 351, and the first actuating lever 37 can slide along the length direction of the first elongated groove 351. In this way, the first support 31 can be driven to rotate around the first axis by the first screw 34.

[0056] Back Figure 3 and Figure 4 In some embodiments, when the second angle adjustment unit 4 is specifically configured, the second angle adjustment unit 4 includes a second support 41, a second active component, and a second driven component. The second support 41 is configured to be detachably fixedly connected to the first support 31, and the end of the second support 41 facing away from the first support 31 is connected to the mounting base 5. The second active component is rotatably disposed at the end of the first support 31 facing away from the connecting base 2. The second driven component is fixedly disposed at the end of the second support 41 near the first support 31 and is drively connected to the second active component. After the first support 31 and the second support 41 are released from fixation, the second driven component can rotate around the second axis L2 under the drive of the second active component.

[0057] In one specific implementation, the second driving component includes a second worm gear 42, which is rotatably mounted on the end of the first support 31 opposite to the connecting seat 2. The axis of the second worm gear 42 is perpendicular to both the first axis L1 and the second axis L2, meaning the axis of the second worm gear 42 is parallel to direction A in the figure. The second driven component includes a second worm wheel 43, which is fixedly mounted on the end of the second support 41 near the first support 31. The axis of the second worm wheel 43 coincides with the second axis L2. The second worm gear 42 and the second worm wheel 43 are meshed together. This worm gear transmission structure has fewer components and is easier to install.

[0058] like Figure 6 As shown, as an alternative, the second driving component includes a second screw 44, which is rotatably mounted on the end of the first support 31 opposite to the connecting seat 2, and the axis of the second screw 44 is perpendicular to the first axis L1 and the second axis L2. The second driven component includes a second nut block 45, a second rotating shaft 46, and a second actuating rod 47. The second rotating shaft 46 is fixedly mounted on the second support 41, and the axis of the second rotating shaft 46 coincides with the second axis. The second nut block 45 is sleeved on the second screw 44 and threadedly connected to the second screw 44; the second actuating rod 47 is located between the second rotating shaft 46 and the second nut block 45, and the axis of the second actuating rod 47 is parallel to the axis of the second rotating shaft 46. The second actuating rod 47 is fixedly connected to the second rotating shaft 46 through a second connecting arm 48. The second nut block 45 is provided with a second long groove 451, the length direction of which is parallel to the first axis; the second actuating rod 47 is at least partially inserted into the second long groove 451, and the second actuating rod 47 can slide along the length direction of the second long groove 451. This allows the second screw 44 to drive the second support 41 and the antenna to rotate around the second axis.

[0059] Back Figure 3 and Figure 4 In some embodiments, the mounting base 5 is detachably fixedly connected to the end of the second support 41 facing away from the first support 31, and an angle adjustment component is provided between the mounting base 5 and the second support 41. The angle adjustment component is used to enable the mounting base 5 to rotate relative to the second support 41 about a third axis L3; wherein, the third axis L3 is parallel to the second axis L2. This allows for manual coarse adjustment of the pitch angle of the mounting base 5 after the fixed connection between the mounting base 5 and the second support 41 is released.

[0060] For example, the angle adjustment assembly includes a limiting groove a, a connecting shaft b, an arc-shaped guide groove c, a connecting hole d, and a fastening assembly. The axis of the connecting shaft b coincides with the third axis L3. One of the mounting base 5 and the second support 41 has a limiting groove a, and the other has a connecting shaft b, which is inserted into the limiting groove a. One of the mounting base 5 and the second support 41 has an arc-shaped guide groove c, and the other has a connecting hole d, which is opposite to the arc-shaped guide groove c. The fastening assembly can cooperate with the arc-shaped guide groove c and the connecting hole d to achieve a detachable fixed connection between the mounting base 5 and the second support 41. After the fixed connection between the mounting base 5 and the second support 41 is released, the mounting base 5 can rotate relative to the second support 41 around the connecting shaft b. In this solution, the structures of both the mounting base 5 and the second support 41 are simplified, which helps to reduce the processing difficulty. For example, the fastening assembly includes screws and nuts.

[0061] The following is combined Figure 3 and Figure 4 This embodiment provides a detailed description of an angle adjustment structure. For example... Figure 3 and Figure 4 As shown, in this angle adjustment structure, both the connecting seat 2 and the second support 41 are U-shaped structures. Specifically, the connecting seat 2 includes two opposing first sub-plates 21 along the extension direction of the first axis L1, and the second support 41 includes two opposing second sub-plates 411 along the extension direction of the second axis L2. The first support 31 includes a U-shaped portion and two third sub-plates 311 connected to the surface of the U-shaped portion facing the connecting seat 2. The U-shaped portion includes two opposing fourth sub-plates 312 along the extension direction of the second axis L2, and the two third sub-plates 311 are arranged opposite each other along the extension direction of the first axis L1. The two first sub-plates 21 and the two third sub-plates 311 are connected one-to-one with screws and nuts, and the two second sub-plates 411 and the two fourth sub-plates 312 are connected one-to-one with screws and nuts. The mounting base 5 includes a base plate and two side plates 51 connected to the base plate and facing the surface of the first support 31. The two side plates 51 are arranged opposite each other along the extension direction of the second axis L2, and the two side plates 51 are connected one-to-one with the two second sub-plates 411 with screws and nuts. The first worm gear 32 is rotatably mounted on the connecting seat 2, and one end of the first worm gear 32 may have a hole adapted to the shape of a general-purpose hex wrench, so as to insert the hex wrench and drive the first worm gear 32 to rotate. The first worm wheel 33 is mounted on a third daughter plate 311, specifically, as shown in... Figure 7 As shown, a third sub-plate 311 has a first shaft 36 whose axis coincides with the first axis L1. The first shaft 36 is used to mount the first worm gear 33 or to connect the first actuating lever; another first sub-plate 21 is fitted with a hole and shaft to the corresponding third sub-plate 311. Figure 5As shown, the first shaft 36 can also connect to two third sub-plates 311. It's easy to understand that in this case, the first shaft 36 can be a one-piece molded structure. Returning to... Figure 3 and Figure 4 The second worm gear 42 is rotatably mounted on a fourth subplate 312, and the second worm wheel 43 is mounted on a second subplate 411. One end of the second worm gear 42 may be provided with a hole that is compatible with the shape of a universal hex wrench, so that the hex wrench can be inserted to drive the second worm gear 42 to rotate.

[0062] Each second sub-plate 411 is provided with a connecting shaft b and an arc-shaped guide groove c. Each side plate 51 is provided with a limiting groove a corresponding to the corresponding connecting shaft b and a connecting hole d corresponding to the arc-shaped guide groove c. The connecting shaft b is inserted into the limiting groove a, and the connecting hole d is opposite to the arc-shaped guide groove c. The fastening assembly includes a screw and a nut. The shank of the screw passes through the arc-shaped guide groove c and the corresponding connecting hole d, and is threadedly connected to the nut.

[0063] It is worth noting that when the external structure is another structure that requires angle adjustment, such as a photovoltaic bracket, the working principle of the first angle adjustment unit 3 and the second angle adjustment unit 4 remain unchanged. The specific angle adjustment achieved by the two can be the angle in other directions in the corresponding scenario, which can be set according to actual needs.

[0064] The antenna device provided in this embodiment includes an antenna 200 and the above-mentioned angle adjustment structure. The antenna 200 is installed on the end of the mounting base 5 away from the second angle adjustment unit 4, and the first axis is used to be perpendicular to the horizontal plane.

[0065] In this scheme, the azimuth angle is adjusted by rotating the antenna 200 around the first axis L1 via the first angle adjustment unit 3, and the elevation angle is adjusted by rotating the antenna 200 around the second axis L2 via the second angle adjustment unit 4. Based on the ability to adjust the azimuth and elevation angles of the antenna 200, the first angle adjustment unit 3 protrudes from the side of the connecting base 2 away from the carrier, and the second angle adjustment unit 4 protrudes from the side of the first angle adjustment unit 3 away from the connecting base 2. The antenna 200 is mounted on the surface of the mounting base 5 away from the connecting base 2, thus making the overall angle adjustment structure larger in the direction away from the carrier. This results in a larger distance between the antenna 200 mounted on the surface of the mounting base 5 away from the second angle adjustment unit 4 and the carrier, making it more suitable for larger antennas 200.

[0066] Back Figure 2 and Figure 3In some embodiments, the antenna device includes a column 100 and at least one connecting component, each connecting component having at least two sets of locking components 12; with the direction perpendicular to the first axis and the second axis as the first direction A, each connecting component includes two opposing limiting members 11 in the first direction A, the two limiting members 11 in each connecting component being respectively disposed on opposite sides of the column 100 in the first direction A; the connecting seat 2 is located on the side of the connecting component where one limiting member 11 faces away from the other limiting member 11, and each connecting component is detachably and fixedly connected to the connecting seat 2 and the column 100 through at least two sets of locking components 12 corresponding to it.

[0067] It should be understood that when multiple connecting components 1 are included, the orientation of each pair of limiting members 11 in each connecting component 1 is the same, and the multiple connecting components 1 are spaced apart along the axial direction of the column 100.

[0068] In one possible implementation, each pair of limiting members 11 (i.e., two limiting members 11 in the same connecting assembly) is detachably and fixedly connected to the connecting seat 2 and the column 100 via at least two sets of locking components 12 corresponding to them. In this way, the azimuth angle of the antenna can be coarsely adjusted by releasing the locking components 12. For example, during coarse adjustment, the locking components 12 can be released to a certain torque, that is, the locking components 12 are not completely disengaged.

[0069] Of course, in other embodiments, the antenna device may include more connecting components 1, and each connecting component 1 may correspond to more sets of locking components 12, which can be set according to actual needs.

[0070] For example, the locking assembly 12 includes screws and nuts for rapid coarse adjustment of the antenna azimuth angle:

[0071] After loosening the nut of the locking assembly 12 to a certain torque, rotating the connecting seat 2 can quickly adjust the azimuth angle of the mounting seat 5 and the antenna.

[0072] When making fine adjustments to the azimuth:

[0073] The first worm gear 32 is rotated by a hex wrench, which in turn drives the first worm wheel 33 to rotate. The first worm wheel 33 is fixedly connected to the first shaft 36, and the first shaft 36 drives the first support to rotate, thus enabling fine adjustment of the azimuth angle of the mounting base 5 and the antenna.

[0074] When performing rapid coarse adjustment of the antenna's elevation angle:

[0075] After loosening the connection between the mounting base 5 and the second support 41 to a certain torque, rotate the mounting base 5 so that it rotates around the connecting shaft b, thereby enabling rapid adjustment of the pitch angle of the mounting base 5 and the external structure.

[0076] When making fine adjustments to the pitch angle:

[0077] By turning the second worm gear 42 with a hex wrench, the second worm wheel 43 is driven to rotate. The second worm wheel 43 is fixedly connected to the shaft, and the shaft drives the second seat 41 to rotate, thus enabling fine adjustment of the elevation angle of the mounting seat 5 and the antenna.
