Description

Technical Field

[0001] The present invention belongs to the technical field of antenna base stations, and specifically relates to a 5G base station antenna array and a 5G base station. Background Art

[0002] A 5G base station is the core equipment of a 5G network, providing wireless coverage and realizing wireless signal transmission between a wired communication network and a wireless terminal. The architecture and form of the base station directly affect how the 5G network is deployed. Since the higher the frequency, the greater the attenuation during signal propagation, the base station density of the 5G network will be higher. 5G will bring a brand-new experience to users, and it has a transmission rate ten times faster than 4G. An antenna is a signal transceiver device of a communication system, and the 5G era has put forward new requirements for the antenna system.

[0003] When installing existing antenna base stations, it is necessary for workers to climb to the top of the antenna tower manually for installation. For relatively complex antenna towers, the installation process is not only complicated but also accompanied by difficulties in inconvenient operation, and there may be a risk of workers falling during the operation process.

[0004] Chinese Patent with the authorization announcement number CN220086377U discloses a 5G base station antenna structure. For this 5G base station antenna structure, by pulling the handle, the upper cover of the protective cover is driven to displace, thereby driving the displacement of two pairs of support rods, and then driving the displacement of the lower cover of the protective cover, so that two pairs of second sliders slide in two pairs of second chutes. Place the antenna inside, then put it back into the outer box body of the protective cover, and then place it on the connecting plate. Screw a pair of first bolts, and make them rotate in the threaded grooves opened on both sides of a pair of fixedly connected blocks and the connecting plate respectively. A pair of nuts provided on the other side play a fixing role, so as to achieve the purpose of convenient fixing of the protective cover mechanism and its convenient disassembly. When debugging the position, screw the knob, which drives the transmission rod to rotate, thereby driving the turbine sleeved thereon to rotate, thereby driving the worm screwed thereon to rotate, thereby driving the rotating connecting rod fixedly connected thereto to rotate, and then driving the connecting plate to rotate, so as to achieve the purpose of adjusting its position. When it needs to be lifted or lowered, first start a pair of electric sliding rods, which drive a pair of electric sliders to displace on the pair of electric sliding rods, so as to achieve the purpose of lifting the inner lifting rod. First sliders provided on one side of a pair of electric sliders respectively slide in a pair of first chutes, so as to achieve the purpose of quickly adjusting the lifting height. At the same time, the angle of the antenna can be conveniently adjusted by screwing the knob, increasing the diversity of its users during use.

[0005] However, this technical solution still has at least the following defects: When installing the 5G base station antenna structure in this solution, it still needs to rely on workers to climb to the top of the antenna tower manually for installation, and there is a risk of workers falling. In view of this, the present invention is specifically proposed. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0042] Embodiment 1

[0043] As Figure 13 shown, a 5G base station antenna array includes a metal reflection bottom plate 500, on which a plurality of antenna array units 501 arranged at equal intervals are installed, and a beam expansion structure is provided between two adjacent antenna array units 501;

[0044] The beam expansion structure is to arrange metal columns 502 in four directions of the antenna array unit 501. The metal columns 502 are perpendicular to the metal reflection bottom plate 500, and two adjacent antenna array units 501 share the metal columns 502;

[0045] Two metal columns 502 are provided in each direction of the antenna array unit 501, and the distance between the metal columns 502 is equal to the diameter of the metal columns 502;

[0046] Select a metal column 502 with a diameter of 2.2 mm and a height of 7 mm, and set it on a pad with a size of 4 mm × 8 mm. The center distance between the two fine copper wires is 4 mm, and the half-power beam width is increased to 99 ± 7°.

[0047] Embodiment 2

[0048] As Figures 1 to 12 shown, a 5G base station includes a base station antenna 100 and an antenna tower 103. The base station antenna 100 includes a 5G base station antenna array. A positioning mechanism is provided inside the base station antenna 100, and the positioning mechanism is used to position and install the base station antenna and the antenna tower 103.

[0049] As Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 shown, in the specific implementation, it further includes a loading mechanism for lifting the base station antenna 100. The loading mechanism includes a moving component and an installation component. The loading mechanism transports the base station antenna 100 to the top of the antenna tower 103 through the moving component, and installs the base station antenna 100 on the antenna tower 103 through the installation component. In this setting, by setting the loading mechanism to replace manual labor to send the base station antenna 100 to the antenna tower 103 and realizing installation without manual labor through the installation component, the risk of high-altitude operation of workers is avoided.

[0050] As Figure 9 、 Figure 10 shown, further, the moving component includes a driving device 206. A support component is provided on one side of the driving device 206, and the support component is used to support and connect the driving device 206 and the installation component. The support component includes an installation frame 201. A first push plate 202 and a second push plate 205 are slidably connected to the bottom of the installation frame 201. One end of the second push plate 205 is rotatably connected to the driving device 206. A slide rod 207 is fixedly installed at the end of the second push plate 205 away from the driving device 206, and one end of the slide rod 207 is movably inserted between the first push plate 202 and one end of the installation frame 201. In this setting, the slide rod 207 and the installation frame 201 provide a supporting force for the driving device 206.

[0051] As Figure 9 、 Figure 10As shown in the figure, further, a elastic force compensation component is provided at the bottom of the support component. The elastic force compensation component includes a special-shaped wheel 204. The special-shaped wheel 204 is rotatably installed at the bottom of the mounting frame 201. A stop bar 203 is provided on one side of the special-shaped wheel 204. Both ends of the stop bar 203 are fixedly installed at one end of the first push plate 202 away from the second push plate 205. A first spring 208 is movably sleeved on the part of the sliding rod 207 between the first push plate 202 and the second push plate 205. The elastic force compensation component adjusts the distance between the stop bar 203 and the second push plate 205 by rotating the special-shaped wheel 204, and changes the deformation amount of the first spring 208. In this setting, the outer edge of the special-shaped wheel 204 is helically arranged. When the special-shaped wheel 204 rotates, its helical shape abuts against the stop bar 203 to make it move. The stop bar 203 drives the first push plate 202 to move, and then drives one end of the first spring 208 to move, so that the change degree of the deformation amount of the first spring 208 during the movement is reduced, avoiding that the elastic force decreases too much and causing the friction force between the driving device 206 and the antenna tower 103 to be insufficient.

[0052] As Figure 9 , Figure 10 shown in the figure, further, transmission components are provided on both sides of the elastic force compensation component. The transmission components include a gear 212 and a rack 211. One end of the gear 212 is fixedly installed with a connecting shaft 213. One end of the connecting shaft 213 is fixedly connected to the special-shaped wheel 204. The rack 211 meshes with the gear 212. And a limiting plate 210 is fixedly installed on one side of the rack 211. A limiting groove with a width adapted to the diameter of the connecting shaft 213 is opened on the limiting plate 210. The limiting plate 210 is movably sleeved on the connecting shaft 213 through the limiting groove. A connecting piece 209 is fixedly installed at one end of the limiting plate 210 and the rack 211. The connecting piece 209 is rotatably connected to the second push plate 205. In this setting, since the antenna tower 103 is thinner at the top and thicker at the bottom, when the driving device 206 rises, it gradually approaches the axis of the antenna tower 103. When the driving device 206 approaches the antenna tower 103, it drives the rack 211 to move. The rack 211 drives the gear 212 to rotate through meshing. The gear 212 drives the special-shaped wheel 204 to rotate through the connecting shaft 213. Through the limiting groove and the connecting shaft 213, the rack 211 can always maintain the meshing state with the gear 212.

[0053] Embodiment 3

[0054] As Figure 7 , Figure 8 , Figure 11 , Figure 12As shown, in the specific implementation manner, the installation component includes an installation plate 200. The top of the moving component is fixedly installed at the bottom of the installation plate 200. A fixing frame 300 is fixedly installed on the installation plate 200. The top of the fixing frame 300 is rotatably connected with a plurality of pulling plates 301. One end of the plurality of pulling plates 301 is rotatably installed with a connecting plate 302. One end of the connecting plate 302 is fixedly installed with an inner clamping block 303. The bottom of the base station antenna 100 is fixedly installed with a support plate 304. The bottom of the support plate 304 is fixedly installed with an outer clamping ring 305. A groove 306 is opened on one side of the outer clamping ring 305. The inner diameter of the outer clamping ring 305 is adapted to the length of the inner clamping block 303. The width of the groove 306 is adapted to the width of the inner clamping block 303. In this setting, while the driving device 206 moves downward, it pulls the connecting plate 302 through the pulling plate 301, and pulls the support plate 304 back to the correct position through the inner clamping block 303 and the outer clamping ring 305, thereby driving the base station antenna 100 to return to the correct position. While the support plate 304 returns to the correct position, it drives the outer clamping ring 305 to move, and aligns the groove 306 on the outer clamping ring 305 with the inner clamping block 303. At this time, when the driving device 206 continues to move downward, it can directly drive the inner clamping block 303 to move out from the groove 306.

[0055] As Figures 3 to 7 shown, further, a clamping mechanism is arranged on the support plate 304. The clamping mechanism includes a plug rod 307 and a second spring 308. The second spring 308 is sleeved on the plug rod 307, and both ends of the second spring 308 are fixedly connected with the support plate 304 and the plug rod 307 respectively. The plug rod 307 is movably inserted into the support plate 304. A jack 309 is opened on the side surface of the antenna tower 103. The jack 309 is adapted to the plug rod 307. The clamping mechanism controls the plug rod 307 to insert into the jack 309 through the second spring 308. In this setting, when the driving device 206 drives the base station antenna 100 to move to the top of the antenna tower 103, the plug rod 307 on the side surface of the support plate 304 is aligned with the jack 309, and at the same time, the pulling force of the second spring 308 makes the plug rod 307 insert into the jack 309.

[0056] As Figure 2 、 Figure 7 shown, further, a support frame 400 is also fixedly installed on the top of the installation plate 200. The top of the support frame 400 is subjected to frosting treatment. There are two installation plates 200, which are rotatably connected to each other, and the two installation plates 200 are connected by bolts. In this setting, by frosting the top of the support frame 400, the friction force between the support frame 400 and the support plate 304 is effectively increased, so as to keep the support plate 304 in a horizontal state during the installation process.

[0057] As Figures 3 to 6As shown in the figure, further, the positioning mechanism includes a placement cavity 101 fixedly installed inside the base station antenna 100. A positioning pile 102 is movably inserted into the placement cavity 101. A positioning hole 104 is opened at the top of the antenna tower 103, and the positioning hole 104 is adapted to the positioning pile 102. The positioning mechanism makes the positioning pile 102 fall into the positioning hole 104 when the base station antenna 100 is perpendicular to the ground. In this setting, when the base station antenna 100 is in a vertical state, the positioning pile 102 in the placement cavity 101 inside it enters the positioning hole 104 under the action of gravity, thus completing the installation of the base station antenna 100.

[0058] The implementation principle of a 5G base station antenna array and a 5G base station in this embodiment is as follows: When installing the base station antenna 100, first open the mounting plate 200 and put it on the antenna tower 103, and fix the mounting plate 200 firmly with bolts. At this time, the driving device 206 abuts against the side wall of the antenna tower 103. Put the outer clamping ring 305 on the bottom support plate 304 of the base station antenna 100 on the inner clamping block 303, and make the side of the support plate 304 rest on the support frame 400. Adjust the angle of the pull plate 301 to keep the side of the support plate 304 in a horizontal state;

[0059] At this time, start the driving device 206. The driving device 206 realizes the extrusion with the antenna tower 103 through the elastic force of the first spring 208, and relies on its frictional force to climb along the antenna tower 103. Since the antenna tower 103 is thinner at the top and thicker at the bottom, the driving device 206 gradually approaches the axis of the antenna tower 103 during the rising process. At this time, the deformation amount of the first spring 208 decreases, resulting in a decrease in the elastic force;

[0060] During the process of the driving device 206 approaching the antenna tower 103, it drives the rack 211 to move. The rack 211 drives the gear 212 to rotate through meshing. The gear 212 drives the special-shaped wheel 204 to rotate through the connecting shaft 213. The special-shaped wheel 204 drives the stop lever 203 to move through its spiral shape. The stop lever 203 drives the first push plate 202 to move. The first push plate 202 reduces the degree of decrease in the deformation amount of the first spring 208 by compressing the first spring 208, preventing the elastic force from decreasing and causing insufficient frictional force between the driving device 206 and the antenna tower 103;

[0061] When the driving device 206 drives the base station antenna 100 to move to the top of the antenna tower 103, the insertion rod 307 on the side of the support plate 304 is aligned with the insertion hole 309. At the same time, the pulling force of the second spring 308 causes the insertion rod 307 to insert into the insertion hole 309. At this time, control the driving device 206 to move downward. While the driving device 206 moves downward, it pulls the connecting plate 302 through the pulling plate 301, and pulls the support plate 304 back to the correct position through the inner clamping block 303 and the outer clamping ring 305, thereby driving the base station antenna 100 to return to the correct position. When the base station antenna 100 is in a vertical state, the positioning pile 102 in its internal placement cavity 101 enters the positioning hole 104, so that the installation of the base station antenna 100 is completed;

[0062] While the support plate 304 returns to the correct position, it drives the outer clamping ring 305 to move, and aligns the groove 306 on the outer clamping ring 305 with the inner clamping block 303. At this time, when the driving device 206 continues to move downward, it can directly drive the inner clamping block 303 to move out from the groove 306.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
