DETAILED DESCRIPTION

[0055] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0056] With reference to Figures 1-8 , the present application provides an antenna device, which can include an antenna body 1, a base 2, a mounting seat 3, a first reinforcing ring 4, a plurality of direction control sliding blocks 5, and a plurality of fixed supports 6, wherein:

[0057] The antenna body 1 is used for transmitting communication signals. The base 2 is located at the bottom end of the antenna body 1, the antenna body 1 is arranged through the top of the base 2, and is movably connected with the base 2. The movable connection can include, but is not limited to, rotary connection, sliding connection, etc. The mounting seat 3 is fixed to the bottom of the base 2, and is used for mounting the device on a support. The support can be a tower body of a communication tower, etc., which is not limited herein. The first reinforcing ring 4 is horizontally sleeved on the circumferential side of the base 2, and is fixedly connected with the base 2. For example, the first reinforcing ring 4 and the base 2 can be fixed by welding, or bolted, or integrally formed.

[0058] With reference to Figure 1 and Figure 2As shown, a control groove 401 is formed on the end surface of the first reinforcing ring 4 away from the base 2. Referring to Figure 1 As shown, the slot of the control groove 401 is horizontally arranged. A plurality of control sliders 5 are located in the control groove 401 and are in sliding connection with the first reinforcing ring 4. The position of the control slider 5 in the horizontal direction is limited by the cross-sectional shape of the control groove 401, so that the control slider 5 will not slide out of the control groove 401 during sliding. Each fixed support 6 extends upward from the control slider 5 to the middle of the side surface of the antenna body 1 and is fixedly connected with the antenna body 1. Pushing and pulling the fixed support 6 drives the antenna body 1 to rotate around the base 2, so as to adjust the azimuth angle of the antenna body 1 and optimize the transmission range of the antenna signal. In an example, when no driving force is applied to the control slider 5, the control slider 5 and the control groove 401 are kept stationary by static friction. The plurality of fixed supports 6 can also support and reinforce the rotating antenna body 1, thereby improving the structural stability of the device.

[0059] An alternative embodiment of the application is shown in Figure 3 As shown, the base 2 is provided with an upwardly open accommodating cavity, and the antenna body 1 and the base 2 can be in sliding connection. The device can further include a second reinforcing ring 7, an upper rotary ring 8, and a rotary motion output assembly 9. Wherein:

[0060] The second reinforcing ring 7 is embedded in the opening of the accommodating cavity and can be fixed to the base 2 by welding or bolting. The upper rotary ring 8 is fixed to the bottom of the antenna body 1 and is in sliding connection with the second reinforcing ring 7 in the horizontal direction. The rotary motion output assembly 9 is used to output rotary motion and is located in the accommodating cavity and fixedly connected with the center of the antenna body 1. The rotary motion output assembly 9 drives the antenna body 1 to rotate when working, so as to adjust the azimuth angle of the antenna body 1. Therefore, the azimuth angle of the antenna body 1 can be automatically adjusted by the rotary motion output assembly 9, thereby optimizing the performance of the product.

[0061] An optional embodiment of the application, the rotating motion output assembly 9 can include a shaft 901 and a drive motor 902. Wherein, the shaft 901 is placed vertically (parallel to the vertical direction), and is fixedly connected with the center of the antenna body 1. The output shaft of the drive motor 902 is coaxially connected with the shaft 901, and the drive motor 902 is fixedly connected with the base 2. Coaxial connection can be understood as the central axis of the output shaft of the drive motor 902 and the central axis of the shaft 901 are collinear (or coincident). Therefore, when the drive motor 902 rotates, it drives the antenna body 1 to rotate through the shaft 901, realizing the adjustment of the azimuth angle of the antenna body 1. And the reciprocating adjustment of the azimuth angle can be realized by controlling the forward and reverse rotation of the drive motor 902, so that the antenna body 1 can be rotated and adjusted to any angle direction, assisting the better transmission of signals, and expanding the range of antenna signal transmission.

[0062] An optional embodiment of the application, referring to Figure 3 and Figure 4 The device can further include a lower swivel 10, two protective tubes 11 and a connecting frame 12. Wherein, the lower swivel 10 is located below the upper swivel 8, and is slidingly connected with the second reinforcing ring 7 in the horizontal direction. The two protective tubes 11 vertically penetrate the lower swivel 10, and are fixedly connected with the lower swivel 10. The connecting frame 12 is connected with the two protective tubes 11 and is fixed with the shaft 901, wherein the drive motor 902 drives the lower swivel 10 to rotate when it is working. The addition of the lower swivel 10 below the upper swivel 8, and the formation of fixation through the connecting frame 12, the protective tube 11 and the shaft 901, can improve the operation stability of the drive motor 902, reduce the axial displacement amount generated when the output shaft of the drive motor 902 and the shaft 901 rotate, and improve the service life of the drive motor 902.

[0063] An optional embodiment of the application, referring to Figure 5 The cross-sectional shape of the output shaft of the drive motor 902 is rectangular, and the shaft 901 is provided with a rectangular groove 9011 matched with the cross-sectional shape of the output shaft of the drive motor 902. The output shaft of the drive motor 902 is inserted into the rectangular groove 9011, and is slidingly connected with the shaft 901. Wherein, the sliding connection mode of the output shaft of the drive motor 902 and the shaft 901 can facilitate disassembly, and will not affect the radial operation stability when the drive motor 902 rotates. Thus, the product performance of the device is further optimized.

[0064] An optional embodiment of the application, referring to Figure 3 , Figure 5 or Figure 6As shown, the shaft 901 comprises a clamping portion 9012, the protective tube 11 is slidingly connected with the connecting frame 12, and the device can further comprise a first lifting rod 13 and a positioning cylinder 14. The first lifting rod 13 is rotatably connected in the antenna body 1, and the output shaft of the first lifting rod 13 is connected with the shaft 901 in the accommodating cavity. The positioning cylinder 14 is fixed with the antenna body 1 and is sleeved on the output shaft of the first lifting rod 13, and a clamping groove 1401 matching the shape of the clamping portion 9012 is formed in the positioning cylinder 14. In an example, the clamping portion 9012 can be sleeved on the shaft 901. In order to facilitate the machining of the clamping portion 9012 and the clamping groove 1401, the cross-sectional shape of the clamping portion 9012 is cross-shaped, and correspondingly, the cross-sectional shape of the clamping groove 1401 can also be cross-shaped.

[0065] When the first lifting rod 13 is retracted, the positioning cylinder 14 is clamped and fixed with the shaft 901, and the fixing of the positioning cylinder 14 and the shaft 901 is realized through the cooperation between the clamping portion 9012 and the clamping groove 1401. When the driving motor 902 rotates, the rotation force output by the driving motor 902 is synchronously transmitted to the positioning cylinder 14 through the clamping portion 9012, so as to drive the antenna body 1 to rotate. When the first lifting rod 13 is extended, the clamping portion 9012 is pushed out of the clamping groove 1401, and at this time, the positioning cylinder 14 and the shaft 901 are separated from each other. In the case that the positioning cylinder 14 and the shaft 901 are separated from each other, the antenna body 1 can be driven to rotate around the base 2 by pushing and pulling the fixed support 6, so as to adjust the azimuth angle of the antenna body 1. Since the driving motor rotates the antenna body 1 to change the angle by a large range, this adjustment mode is suitable for adjusting the azimuth angle in a large range.

[0066] In an optional embodiment of the application, referring to Figure 6 As shown, the device further comprises a limiting disc 15 and a disc 16. The limiting disc 15 is embedded in the antenna body 1. For example, the limiting disc 15 is fixedly connected with the antenna body 1, the disc 16 is horizontally embedded in the limiting disc 15 and is slidingly connected with the limiting disc 15, and the disc 16 is fixedly connected with the first lifting rod 13. The rotating connection between the first lifting rod 13 and the antenna body 1 is realized through the cooperation of the limiting disc 15 and the disc 16. When the antenna body 1 rotates, the first lifting rod 13 remains in a stationary state, that is, does not rotate with the antenna body 1.

[0067] In an optional embodiment of the application, referring to Figure 7 and Figure 8As shown, the side of the positioning cylinder 14 is provided with a sliding groove. The sliding groove further comprises a plurality of vertical groove portions 1402 and a plurality of arc-shaped groove portions 1403 in communication with the vertical groove portions 1402. The vertical groove portions 1402 are vertically arranged on the side of the positioning cylinder 14. The arc-shaped groove portions 1403 are curvedly extended from the top end of one of the vertical groove portions 1402 to the bottom end of the vertical groove portion 1402 adjacent to the one of the vertical groove portions 1402. The plurality of vertical groove portions 1402 and the plurality of arc-shaped groove portions 1403 are alternately arranged.

[0068] The rotation motion output assembly 9 can further comprise a plurality of angle fine adjustment units. For example, the number of the angle fine adjustment units is 2, and the two angle fine adjustment units can be symmetrically installed about the center of the positioning cylinder 14. The angle fine adjustment unit can comprise a fixing rod 903, a mounting bracket 904, a second lifting rod 905, a guide slide rail 906, a guide seat 907, a sliding rod 908, a connecting rod 909, a limiting spring 910, and a pushing bracket 911. Wherein:

[0069] The fixing rod 903 is horizontally arranged (i.e. the fixing rod 903 is parallel to the horizontal direction) and fixedly connected with the lower swivel joint 10. The mounting bracket 904 is fixedly connected with the fixing rod 903. The second lifting rod 905 is fixed on the mounting bracket 904, and the output shaft of the second lifting rod 905 is vertically downward arranged. The guide slide rail 906 is fixed on the mounting bracket 904 and placed parallel to the second lifting rod 905. The guide seat 907 is slidingly connected with the guide slide rail 906. The sliding rod 908 is extended from the guide seat 907 into the sliding groove and abuts against the sliding groove. The connecting rod 909 is vertically placed and fixedly connected with the guide seat 907. The limiting spring 910 is arranged between the bottom of the guide slide rail 906 and the guide seat 907 and sleeved on the connecting rod 909. The pushing bracket 911 is horizontally installed between the second lifting rod 905 and the connecting rod 909. When the second lifting rod 905 is extended or retracted, the sliding rod 908 drives the positioning cylinder 14 to rotate, so as to adjust the azimuth angle of the antenna body 1.

[0070] When the first lifting rod 13 is extended, the positioning cylinder 14 is separated from the shaft rod 901. At this time, the second lifting rods 905 on both sides are synchronously operated, so that the second lifting rods 905 on both sides push the pusher frames 911 on both sides to move up and down in opposite directions (when the second lifting rod 905 on one side pushes the pusher frame 911 to move downward, the second lifting rod 905 on the other side is controlled to push the pusher frame 911 to move upward). The pusher frame 911 penetrates through the bottom surface of the guide rail 906 and moves in sliding mode, and the guide seat 907 and the sliding rod 908 are synchronously moved up and down when the pusher frame 911 slides. The guide seat 907 compresses or stretches the limiting spring 910 up and down, and the sliding rod 908 abuts against the arc-shaped groove part 1403. During the up-and-down movement of the sliding rod 908, the sliding rod 908 controls the positioning cylinder 14 to rotate by pushing the arc-shaped groove part 1403. When the sliding rod 908 moves from the arc-shaped groove part 1403 to the vertical groove part 1402, the positioning cylinder 14 completes a rotation by a certain angle at this time, and the reversely operated second lifting rod 905 controls the pusher frame 911 to move, so that the sliding rod 908 enters another arc-shaped groove part 1403 at the initial end during the up-and-down movement of the sliding rod 908. Thus, the positioning cylinder 14 rotates by equal angles, and the antenna body 1 also rotates by equal angles in stages, so as to realize small-range azimuth adjustment.

[0071] The first lifting rod 13 and the second lifting rod 905 are both electric lifting rods. The device can further include a controller, the controller is integrated with a wireless transmission module, the first lifting rod 13, the second lifting rod 905 and the driving motor 902 are electrically connected with the controller, and the working states of the first lifting rod 13, the second lifting rod 905 and the driving motor 902 can be controlled through the controller. Thus, the azimuth of the antenna body 1 can be remotely controlled, manual high-altitude operation is avoided, and the adjustment safety factor of the antenna body 1 is improved. Meanwhile, the adjustment cost of the antenna body 1 is reduced.

[0072] In conclusion, the application discloses an antenna device, which comprises an antenna body 1, a base 2, a mounting seat 3, a first reinforcing ring 4, a plurality of direction control sliders 5 and a plurality of fixing supports 6.
