Description

[0002] 5G base stations are the core equipment of 5G networks, providing wireless coverage and realizing wireless signal transmission between wired communication networks and wireless terminals. The architecture and form of base stations directly affect how 5G networks are deployed. Since the higher the frequency, the greater the attenuation of the signal during propagation, the base station density of 5G networks will be higher. 5G will bring a new experience to users, with a transmission rate ten times faster than 4G. Antennas are signal transceivers of communication systems, and the 5G era has put forward new requirements for antenna systems.

[0003] When installing existing antenna base stations, workers need to manually climb to the top of the antenna tower to install them. For more complex antenna towers, the installation process is not only complicated, but also accompanied by inconvenient operations. Workers may be at risk of slipping and falling during the operation.

[0004] A Chinese patent with authorization announcement number CN220086377U discloses a 5G base station antenna structure. The 5G base station antenna structure drives the upper cover of the protective cover to move by pulling the handle, thereby driving the displacement of two pairs of support rods, thereby driving the displacement of the lower cover of the protective cover, so that the two pairs of second sliders slide in the two pairs of second slide grooves, and the antenna is placed therein, and then it is put back into the outer box of the protective cover, and then it is placed on the connecting plate, and a pair of first bolts are screwed to rotate in the threaded grooves opened on both sides of a pair of fixed connecting blocks and the connecting plate, and a pair of nuts on the other side play a fixing role, thereby achieving the purpose of conveniently fixing the protective cover mechanism and facilitating its disassembly, and by placing it in the debugging position When the device is in the correct position, the knob is turned to drive the transmission rod to rotate, thereby driving the turbine mounted thereon to rotate, thereby driving the worm screwed thereon to rotate, thereby driving the rotating connecting rod fixedly connected thereon to rotate, and then driving the connecting plate to rotate, thereby achieving the purpose of adjusting the starting position. When it is necessary to lift it, a pair of electric slide bars is started first, thereby driving a pair of electric sliders to move on a pair of electric slide bars, thereby achieving the purpose of raising the inner lifting rod, wherein a first slide bar provided on one side of a pair of electric slide bars slides in a pair of first slide grooves respectively, thereby achieving the purpose of quickly adjusting the lifting height, and at the same time, the angle of the antenna can be conveniently adjusted by turning the knob, thereby increasing the diversity of its users when using it.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0021] Example 1 like Fig.13 As shown, a 5G base station antenna array includes a metal reflective base plate 500, on which a plurality of antenna array units 501 arranged at equal intervals are mounted, and a beam expansion structure is arranged between two adjacent antenna array units 501; The beam expansion structure is to set metal columns 502 in four directions of the antenna array unit 501, the metal columns 502 are perpendicular to the metal reflective bottom plate 500, and two adjacent antenna array units 501 share the metal column 502; There are two metal pillars 502 in each direction of the antenna array unit 501, and the spacing between the metal pillars 502 is equal to the diameter of the metal pillars 502; A metal column 502 with a diameter of 2.2 mm and a height of 7 mm is selected and set on a pad with a size of 4 mm×8 mm. The center distance between the two thin copper wires is 4 mm, and the half-power beam width is increased to 99±7°.

[0022] Example 2 like Figures 1 to 12 As 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 in the base station antenna 100, and the positioning mechanism is used to position and install the base station antenna and the antenna tower 103.

[0023] like Figure 1 , Figure 2, Figure 7 , Figure 8 As shown, in a specific embodiment, a loading mechanism for lifting the base station antenna 100 is also included, and 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, the loading mechanism is set to replace manual labor to send the base station antenna 100 to the antenna tower 103, and the installation component is used to achieve manual installation, thereby avoiding the risk of workers working at high altitudes.

[0024] like Fig. 9 , Fig.10 As shown, further, the moving assembly includes a driving device 206, a supporting assembly is provided on one side of the driving device 206, and the supporting assembly is used to support and connect the driving device 206 and the mounting assembly, and the supporting assembly includes a mounting frame 201, and the bottom of the mounting frame 201 is slidably connected with a first push plate 202 and a second push plate 205, one end of the second push plate 205 is rotatably connected with the driving device 206, and a sliding rod 207 is fixedly installed at one end of the second push plate 205 away from the driving device 206, and one end of the sliding rod 207 is movably plugged between the first push plate 202 and one end of the mounting frame 201. In this configuration, the supporting force for the driving device 206 is provided by the sliding rod 207 and the mounting frame 201.

[0025] like Fig. 9 , Fig.10 As shown, further, an elastic compensation component is provided at the bottom of the supporting component, and the elastic compensation component includes a special-shaped wheel 204, and the special-shaped wheel 204 is rotatably installed at the bottom of the mounting frame 201, and a blocking rod 203 is provided on one side of the special-shaped wheel 204, and both ends of the blocking rod 203 are fixedly installed at one end of the first push plate 202 away from the second push plate 205, and the sliding rod 207 is located between the first push plate 202 and the second push plate 205, and is movably sleeved with a first spring 208. The elastic compensation component adjusts the distance between the blocking rod 203 and the second push plate 205 by rotating the special-shaped wheel 204, and changes the deformation of the first spring 208. In this configuration, the outer edge of the shaped wheel 204 is spirally configured. When the shaped wheel 204 rotates, its spiral shape presses against the blocking rod 203 to move it. The blocking rod 203 drives the first push plate 202 to move, and then drives one end of the first spring 208 to move, thereby reducing the degree of change in the deformation of the first spring 208 during the movement, thereby avoiding excessive reduction in the elastic force, which may cause insufficient friction between the drive device 206 and the antenna tower 103.

[0026] like Fig. 9 , Fig.10As shown, further, transmission components are arranged on both sides of the elastic force compensation component, and the transmission components include a gear 212 and a rack 211. A connecting shaft 213 is fixedly installed at one end of the gear 212, and one end of the connecting shaft 213 is fixedly connected to the special-shaped wheel 204. The rack 211 and the gear 212 are meshed with each other, and a limiting plate 210 is fixedly installed on one side of the rack 211. A limiting groove with a width matching 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 on one end of the limiting plate 210 and the rack 211, and the connecting piece 209 is rotatably connected to the second push plate 205. In this configuration, since the antenna tower 103 is thin at the top and thick at the bottom, the driving device 206 gradually approaches the axis of the antenna tower 103 during the rising process. The driving device 206 drives the rack 211 to move during the approaching process of the antenna tower 103. 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 rack 211 can always maintain a meshing state with the gear 212 through the limiting groove and the connecting shaft 213.

[0027] Example 3 like Figure 7 , Figure 8 , Fig.11 , Fig.12 As shown, in a specific embodiment, the mounting assembly includes a mounting plate 200, the top of the movable assembly is fixedly mounted on the bottom of the mounting plate 200, a fixing frame 300 is fixedly mounted on the mounting plate 200, a plurality of pull plates 301 are rotatably connected to the top of the fixing frame 300, a connecting plate 302 is rotatably mounted on one end of the plurality of pull plates 301, an inner clamping block 303 is fixedly mounted on one end of the connecting plate 302, a supporting plate 304 is fixedly mounted on the bottom of the base station antenna 100, an outer clamping ring 305 is fixedly mounted on the bottom of the supporting plate 304, a groove 306 is provided on one side of the outer clamping ring 305, an inner diameter of the outer clamping ring 305 is adapted to the length of the inner clamping block 303, and a width of the groove 306 is adapted to the width of the inner clamping block 303. In this configuration, when the driving device 206 moves downward, it pulls the connecting plate 302 through the pull plate 301, and pulls the support plate 304 back to the center through the inner clamping block 303 and the outer clamping ring 305, thereby driving the base station antenna 100 to return to the center. When the support plate 304 returns to the center, 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, the driving device 206 continues to move downward to directly drive the inner clamping block 303 to move out of the groove 306.

[0028] like Figures 3 to 7As shown, further, a clamping mechanism is provided on the support plate 304, and 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 the two ends of the second spring 308 are respectively fixedly connected to the support plate 304 and the plug rod 307. The plug rod 307 is movably plugged into the support plate 304. A plug hole 309 is provided on the side of the antenna tower 103, and the plug hole 309 is adapted to the plug rod 307. The clamping mechanism controls the plug rod 307 to be inserted into the plug hole 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 of the support plate 304 is aligned with the plug hole 309, and the tension of the second spring 308 causes the plug rod 307 to be inserted into the plug hole 309.

[0029] like Figure 2 , Figure 7 As shown, further, a support frame 400 is fixedly mounted on the top of the mounting plate 200, the top of the support frame 400 is frosted, and two mounting plates 200 are provided, which are rotatably connected to each other, and the two mounting plates 200 are connected by bolts. In this configuration, by frosting the top of the support frame 400, the friction between the support frame 400 and the support plate 304 is effectively increased, thereby maintaining the horizontal state of the support plate 304 during the installation process.

[0030] like Figures 3 to 6 As shown, further, the positioning mechanism includes a placement cavity 101, the placement cavity 101 is fixedly installed inside the base station antenna 100, a positioning pile 102 is movably inserted inside the placement cavity 101, a positioning hole 104 is opened on the top of the antenna tower 103, the positioning hole 104 is adapted to the positioning pile 102, and the positioning mechanism makes the positioning pile 102 fall into the positioning hole 104 when the base station antenna 100 is vertical 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, so that the base station antenna 100 is installed.

[0031] The implementation principle of a 5G base station antenna array and a 5G base station of 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 firmly install the mounting plate 200 by bolts. At this time, the driving device 206 is against the side wall of the antenna tower 103, and the outer clamping ring 305 on the bottom support plate 304 of the base station antenna 100 is put on the inner clamping block 303, and the side of the support plate 304 is placed on the support frame 400, and the side of the support plate 304 is kept in a horizontal state by adjusting the angle of the pull plate 301; At this time, the driving device 206 is started. The driving device 206 is squeezed against the antenna tower 103 by the elastic force of the first spring 208, and the driving device 206 climbs along the antenna tower 103 by relying on its friction force. Since the antenna tower 103 is thin at the top and thick 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 of the first spring 208 is reduced, resulting in a reduction in elastic force. The driving device 206 drives the rack 211 to move when approaching the antenna tower 103. The rack 211 drives the gear 212 to rotate by meshing. The gear 212 drives the shaped wheel 204 to rotate through the connecting shaft 213. The shaped wheel 204 drives the blocking rod 203 to move by its spiral shape. The blocking rod 203 drives the first push plate 202 to move. The first push plate 202 reduces the degree of reduction of the deformation of the first spring 208 by compressing the first spring 208, thereby preventing the friction between the driving device 206 and the antenna tower 103 from being insufficient due to the reduction of the elastic force. 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, and the tension of the second spring 308 causes the insertion rod 307 to be inserted into the insertion hole 309. At this time, the driving device 206 is controlled 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 center through the inner clamping block 303 and the outer clamping ring 305, thereby driving the base station antenna 100 to return to the center. When the base station antenna 100 is in a vertical state, the positioning pile 102 in the internal placement cavity 101 enters the positioning hole 104, so that the base station antenna 100 is installed; When the support plate 304 returns to the normal position, it drives the outer retaining ring 305 to move and aligns the groove 306 on the outer retaining ring 305 with the inner clamping block 303. At this time, the driving device 206 continues to move downward to directly drive the inner clamping block 303 to move out of the groove 306.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
