[0002] In modern society, the popularity of communication networks has greatly facilitated people's lives, and base stations, as key facilities in communication networks, undertake the important task of signal transfer. However, these base station equipment are often exposed to the external environment, especially in extremely severe weather such as strong winds. Due to the lack of effective protection structures, the existing antenna equipment will be damaged by the wind blowing the antenna bracket. This damage not only increases maintenance costs, but also requires manual removal of the transceiver equipment to prevent the strong wind from damaging the antenna. This operation is not only time-consuming and labor-intensive, but also affects the efficiency of sending and receiving communication signals.

DETAILED DESCRIPTION

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0057] See also Figure 1-Figure 11 An automatically foldable communication antenna provided by an embodiment of the present invention includes an antenna folding support platform 6, and further includes:

[0058] A control folding and unfolding seat 7, wherein the control folding and unfolding seat 7 is fixedly mounted on the antenna folding support platform 6;

[0059] and a folding control mechanism, the folding control mechanism is respectively connected to the antenna folding support platform 6 and the control folding and unfolding seat 7, wherein the folding control mechanism includes a folding state adjustment component and an antenna folding and unfolding component 10;

[0060] The folding state adjustment component is connected to the antenna folding support platform 6, the antenna folding and unfolding component 10 is connected to the control folding and unfolding seat 7, and an antenna mounting seat 33 is fixedly mounted on the antenna folding and unfolding component 10;

[0061] The antenna retractable and deployable assembly 10 includes a retractable and deployable support plate 12, a T-shaped retractable and deployable frame 15 and a retractable and deployable adjustment unit. The number of the retractable and deployable support plates 12 is multiple, and the multiple retractable and deployable support plates 12 are longitudinally distributed above the control retractable and deployable seat 7;

[0062] A plurality of T-shaped retractable and unfolding frames 15 are fixedly mounted on each of the retractable and unfolding support plates 12, wherein a group of the T-shaped retractable and unfolding frames 15 are fixedly connected to the control retractable and unfolding seat 7, and in the longitudinal direction of the control retractable and unfolding seat 7, adjacent T-shaped retractable and unfolding frames 15 are slidably connected, and the retractable and unfolding adjustment units are respectively connected to the retractable and unfolding support plates 12 and the T-shaped retractable and unfolding frames 15.

[0063] During the use of the communication antenna, first, the folding state adjustment component is started to change the antenna folding and unfolding component 10 from a vertical state to a horizontal state (the position state of the antenna folding and unfolding component 10 can be changed according to the conditions of use and transportation of the communication antenna. For example, in the transportation state, in order to save space, it may be more appropriate for the antenna folding and unfolding component 10 to be in a horizontal state. During use, the antenna folding and unfolding component 10 is in a vertical state, which can increase the height of the communication antenna and ensure effective signal transmission. Of course, the vertical, horizontal or inclined position state of the antenna folding and unfolding component 10 can also be adjusted according to the convenience of operation, which will not be described in detail here). In addition, When the antenna folding and unfolding assembly 10 is in a horizontal state, it is convenient for the staff to install the communication antenna on the antenna mounting seat 33, and to repair the various components on the antenna folding and unfolding assembly 10, so as to avoid the occurrence of safety accidents caused by the staff climbing up. Then, the folding state adjustment assembly is fixed in the specified area, and the antenna folding support platform 6 is pushed to rotate, so that the antenna folding and unfolding assembly 10 on the antenna folding support platform 6 is restored from the horizontal state to the vertical state again, and the communication antenna on the antenna mounting seat 33 is also moved to the vertical state. At this time, according to actual needs, some or all of the folding and unfolding adjustment units can be started. Under the driving action of the folding and unfolding adjustment units, some Or all the retractable support plates 12 will move upward, and the distance between adjacent retractable support plates 12 will increase. When the distance between the two retractable support plates 12 increases, relative sliding will occur between the two adjacent T-shaped retractable support frames 15 in the longitudinal direction to ensure smooth movement between the two retractable support plates 12, and when the distance between the two adjacent retractable support plates 12 is the largest, the two retractable support plates 12 will be positioned under the control of the retractable adjustment unit to ensure that the retractable support plates 12 can play a stable supporting role during the subsequent use of the communication antenna. After adjusting the distance between the retractable support plates 12, the height of the communication antenna can be adjusted, and the height of the communication antenna can be adjusted according to the retractable adjustment unit. The number of working units can make the communication antenna operate at different heights, which is beneficial to improving the practicality and flexibility of the equipment (at the end of use or when the antenna folding and unfolding assembly 10 and the communication antenna need to be repaired, it is only necessary to change the working state of the folding and unfolding adjustment unit to fold the multiple folding and unfolding support plates 12 again and turn the antenna folding and unfolding assembly 10 and the communication antenna to a horizontal state for the convenience of staff operation, which will not be elaborated here), and because the wind-exposed area of ​​the folding and unfolding support plates 12, the T-shaped folding and unfolding frame 15 and the folding and unfolding adjustment unit is small, the stability of the communication antenna installation can be guaranteed in windy weather, which provides convenience for the staff.

[0064] In one embodiment of the present invention, see Figure 1-Figure 11 The folded state adjustment component includes a folded state adjustment platform 1, an L-shaped control rod 3 and a telescopic drive unit;

[0065] The telescopic driving unit is connected to the antenna folding support platform 6, and the folding state adjustment platform 1 is connected to the telescopic driving unit;

[0066] One end of the L-shaped control rod 3 is rotatably connected to the folded state adjustment platform 1 , and the other end of the L-shaped control rod 3 is rotatably connected to the telescopic driving unit.

[0067] The telescopic drive unit comprises:

[0068] A telescopic driving member 4, wherein the telescopic driving member 4 is fixedly mounted on the folded state adjusting platform 1;

[0069] A movable joint 5, wherein the movable joint 5 is fixedly connected to the output end of the telescopic driving member 4;

[0070] And a flip support rod 9, one end of which is fixedly connected to the antenna folding support platform 6 and is rotatably connected to the other end of the L-shaped control rod 3, and the other end of the flip support rod 9 is rotatably connected to the movable joint 5.

[0071] The folding state adjustment platform 1 further includes: a control system 8, which is fixedly mounted on the folding state adjustment platform 1 and electrically connected to the folding control mechanism;

[0072] and a fixing portion 2 , wherein the fixing portion 2 is located in the middle of the folded state adjustment platform 1 .

[0073] When the position state of the antenna retractable assembly 10 needs to be changed (for example, due to space limitations such as installation or transportation), the telescopic drive member 4 is started. The telescopic drive member 4 can be in the form of a telescopic cylinder, which can push the movable joint 5 to move and push the flip support rod 9 to move synchronously. When one end of the flip support rod 9 moves, the flip support rod 9 can be pulled by the L-shaped control rod 3 to rotate clockwise (such as Figure 3 As shown in the figure), during the rotation of the flip support rod 9, the antenna folding support platform 6, the control folding and unfolding seat 7 and the antenna folding and unfolding assembly 10 can be driven to rotate synchronously, so that the antenna folding and unfolding assembly 10 can be transformed from a vertical state to a horizontal state, thereby facilitating the maintenance and replacement of various components. On the contrary, starting the telescopic drive member 4 to move in the reverse direction can pull the flip support rod 9 to rotate in the reverse direction, so that the antenna folding and unfolding assembly 10 and the communication antenna are restored to their original positions again.

[0074] In one embodiment of the present invention, see Figure 1-Figure 11 , the expansion and contraction adjustment unit comprises:

[0075] An electromagnetic control component 13, wherein the number of the electromagnetic control components 13 is plural, and the plurality of electromagnetic control components 13 are respectively fixedly mounted on the plurality of the retractable and deployable support plates 12;

[0076] A limit control opening 16, wherein the limit control opening 16 is provided on the T-shaped stowage and unfolding frame 15;

[0077] And an automatic clutch module, which is connected to the retractable support plate 12 and the limit control port 16 respectively.

[0078] The retractable support plate 12 further includes: an interference alarm 11, the number of the interference alarm 11 is multiple, and the multiple interference alarms 11 are respectively fixedly connected to the multiple retractable support plates 12, and are electrically connected to the electromagnetic control component 13;

[0079] And a buffer support rod 14, the number of which is plural, and the plural buffer support rods 14 are respectively fixedly mounted on the plural retractable support plates 12, and when the plural retractable support plates 12 are in a retracted state close to each other, the other end of the buffer support rod 14 abuts against the bottom of the adjacent retractable support plate 12.

[0080] When the antenna retractable and unfoldable assembly 10 is restored to a vertical state, some or all of the electromagnetic control elements 13 are started, wherein the electromagnetic control element 13 can be in the form of an electromagnet. Since the magnetic force required by each electromagnetic control element 13 is different (the electromagnetic control element 13 located at the bottom requires a larger magnetic force to push the upper retractable and unfoldable support plate 12 to move due to the larger gravity), the circuits of the multiple electromagnetic control elements 13 are independent, and each electromagnetic control element 13 is controlled by a separate circuit. After some or all of the electromagnetic control elements 13 are energized, the distance between adjacent retractable and unfoldable support plates 12 can be gradually increased under the action of the magnetic repulsion between adjacent electromagnetic control elements 13. In addition, after the electromagnetic control element 13 is energized, the interference alarm 11 on the corresponding retractable and unfoldable support plate 12 will be energized to work (since in the area where the distance between adjacent retractable and unfoldable support plates 12 increases, although the change in the distance between adjacent retractable and unfoldable support plates 12 can be achieved). The interference alarm 11 is powered on and started, and a buzzer or an existing small fan or the like is generated to drive the birds to stay in the area where the distance between the adjacent retractable and unfolded support plates 12 increases, so as to avoid affecting the normal use of the electromagnetic control component 13. In the area where the distance between the adjacent retractable and unfolded support plates 12 remains unchanged, the birds cannot stay due to the small space, and when the electromagnetic control component 13 is not powered on, the interference alarm 11 will not be put into operation, thereby achieving the purpose of saving resources. In addition, a plurality of buffer support rods 14 are arranged between the adjacent retractable and unfolded support plates 12, which can play a buffering role when the retractable and unfolded support plates 12 with increased spacing return to their original positions, thereby avoiding the situation where the components collide with each other. No further elaboration is made here.

[0081] In one embodiment of the present invention, see Figure 1-Figure 11 , the automatic clutch module comprises:

[0082] A positioning notch 23, wherein the positioning notch 23 is formed in the limit control opening 16, and a limit slot 21 is also formed on the positioning notch 23;

[0083] An anti-slip spherical groove 22, the anti-slip spherical groove 22 is opened on the inner top wall of the limit control opening 16;

[0084] A reset top column 17, wherein the reset top column 17 is fixedly mounted on the inner bottom wall of the limit control opening 16;

[0085] And a clutch control member, which is fixedly connected to the retractable support plate 12 and is detachably connected to the reset top column 17, the limit slot 21, the anti-slip spherical slot 22 and the positioning notch 23 respectively.

[0086] The clutch control component includes a positioning control box 18, an adjusting pressure rod 19, a fixed card plate 20, a spring 24, a telescopic control block 27 and a reset structure. The positioning control box 18 is fixedly mounted on the retractable support plate 12;

[0087] The positioning control box 18 is also provided with an adjusting pressure rod 19, which is slidably connected to the positioning control box 18 and detachably connected to the anti-slip spherical groove 22, and a telescopic control block 27 is fixedly mounted on the adjusting pressure rod 19, and the telescopic control block 27 is located in the positioning control box 18;

[0088] Each of the positioning control boxes 18 is also equipped with two fixed card plates 20, which are symmetrically arranged on both sides of the positioning control box 18, and the fixed card plates 20 are also connected to the inner wall of the positioning control box 18 through a spring 24;

[0089] A reset structure is also provided in the positioning control box 18 , and the reset structure is connected to the adjusting pressure rod 19 and is detachably connected to the reset top column 17 .

[0090] The reset structure includes a T-shaped slider 29, a spring 2 30, a connecting port 31 and a reset slide chamber 32, and the reset slide chamber 32 is opened on the positioning control box 18;

[0091] The T-shaped slider 29 is slidably mounted in the reset slide chamber 32 and is fixedly connected to the adjustment pressure rod 19, and the T-shaped slider 29 is also connected to the inner wall of the reset slide chamber 32 through a fixed clamping plate 20;

[0092] A connecting port 31 is provided at the bottom of the positioning control box 18, and the connecting port 31 is connected to the reset slide chamber 32. When the plurality of retractable support plates 12 are in a retracted state close to each other, the top end of the reset top column 17 passes through the connecting port 31, and is inserted into the reset slide chamber 32 and abuts against the T-shaped slider 29.

[0093] It also includes: a positioning thin plate 1 26 and a positioning thin plate 28, wherein the positioning thin plate 1 26 and the positioning thin plate 28 are both located on the adjusting pressure rod 19 and are respectively located on the upper and lower sides of the telescopic control block 27;

[0094] And a magnetic attraction portion 25 , wherein the magnetic attraction portion 25 is fixedly mounted on the end of the fixed clamping plate 20 .

[0095] After the electromagnetic control member 13 is started, the upper retractable support plate 12 moves upward under the action of the magnetic repulsion force. During the movement of the retractable support plate 12, the upper T-shaped retractable frame 15 slides on the lower T-shaped retractable frame 15, and the positioning control box 18 on the upper retractable support plate 12 moves upward in the limit control port 16. At this time, the positioning control box 18 gradually separates from the reset top column 17. As the positioning control box 18 drives the adjustment pressure rod 19 to move upward, the adjustment pressure rod 19 will eventually enter the anti-skid spherical groove 22, and under the thrust of the anti-skid spherical groove 22, the adjustment pressure rod 19 will move downward in the positioning control box 18. At this time, the telescopic control block 27 pushes the two fixed card plates 20 to move to both sides, and the spring 2 4 is gradually in a stretched state. At the same time, under the pushing action of the telescopic control block 27, the fixed card plate 20 will enter the positioning notch 23. The telescopic control block 27 can adopt a structure combining two cones. Both ends of the fixed card plate 20 can slide on the telescopic control block 27, and under the pushing action of the telescopic control block 27, the fixed card plate 20 can be moved in both directions on the positioning control box 18 and placed in the limit card slot 21 (the limit card slot 21 can also limit the left and right moving distance of the fixed card plate 20). At this time, stop energizing the electromagnetic control member 13, then under the action of the gravity of the retractable support plate 12, the retractable support plate 12 will move downward for a small distance, and the adjusting pressure rod 19 will also move upward under the pushing action of the spring 230. The fixed card plate 20 can be pressed into the limit card slot 21 at this time, so that the adjacent folding and unfolding support plates 12 can be limited, ensuring the stability of the adjacent folding and unfolding support plates 12 at a certain distance (in addition, under some use conditions, such as strong winds, the direction of the current passed into the electromagnetic control component 13 can also be changed at the same time, so that a magnetic attraction is generated between the adjacent folding and unfolding support plates 12, so as to further improve the stability of the adjacent folding and unfolding support plates 12 in the extended state. The electromagnetic control component 13 can be controlled manually or automatically according to actual needs, which will not be described in detail here). When the communication antenna needs to be folded, it is only necessary to start the electromagnetic control component 13 again and increase the current passed into the electromagnetic control component 13 simultaneously, which can increase the distance accordingly. Due to the magnetic repulsion between the adjacent expansion and contraction support plates 12, the positioning control box 18 will move upward a greater distance (compared with the normal moving distance). At this time, the adjusting pressure rod 19 will push the telescopic control block 27 to continue to move downward until the fixed card plate 20 moves to the top of the telescopic control block 27. At this time, the two fixed card plates 20 will move synchronously toward the inner side of the positioning control box 18 under the pulling force of the spring 1 24. When the fixed card plate 20 shrinks into the positioning control box 18 (the positioning notch 23 will not limit the fixed card plate 20), the current passed into the electromagnetic control component 13 is gradually reduced, and under the gravity of the expansion and contraction support plate 12, it gradually moves downward slowly. At this time, the positioning control box 18 moves downward in the limit control port 16.When the positioning control box 18 moves to the bottom of the limit control opening 16 (wherein the upper and lower spaces of the limit control opening 16 are relatively large, so that the fixed card plate 20 can smoothly extend outward from the positioning control box 18, and the middle space of the limit control opening 16 is relatively small, so as to block the fixed card plate 20 at the upper position of the limit control opening 16, thereby forming a limiting effect, ensuring the stability of the distance between the adjacent retractable and deployable support plates 12 after the distance is increased, and further ensuring the stability of the communication antenna after installation), the reset top column 17 will be inserted into the reset sliding chamber 32 through the connecting port 31, and as the positioning control box 18 continues to move downward, and as the space below the limit control opening 16 gradually increases, the reset top column 17 will be inserted into the reset sliding chamber 32 through the connecting port 31. Increased, under the action of the spring 2 30 elastic force and the thrust of the reset top column 17 on the T-shaped slider 29, the adjusting pressure rod 19 and the telescopic control block 27 can be moved up synchronously. At this time, the telescopic control block 27 will push the fixed card plate 20 to move in the two sides of the positioning control box 18, and restore the fixed card plate 20 to the bottom of the telescopic control block 27 again, so as to facilitate the next extension of the communication antenna. In addition, through the cooperation of the magnetic suction part 25, the positioning sheet 1 26 and the positioning sheet 2 28, the fixed card plate 20 can be more stably placed above or below the telescopic control block 27, thereby ensuring that the fixed card plate 20 is always in the correct position, which will not be described in detail here.
