[0062] As described in the background art, in the prior art, an operator climbs to the top of a building or a tower to manually adjust the downtilt angle of the antenna relative to the pole, which reduces the adjustment efficiency and affects the personal safety of the operator.

[0063] The reason for this problem is that the base station antenna system in the prior art cannot remotely adjust the downtilt angle of the antenna. For example, when adjusting the downtilt angle of the antenna in the prior art, the operator needs to climb to the location of the antenna, and then adjust the distance between the top of the antenna and the pole by adjusting the connector for connecting the antenna to the pole, so as to adjust the downtilt angle of the antenna. In this way, every time the downtilt angle of the antenna needs to be adjusted, the operator needs to climb to a high altitude to manually adjust the connector, which reduces the adjustment efficiency of the antenna downtilt angle and affects the personal safety of the operator.

[0064] In response to the above technical problems, an embodiment of the present application provides a base station antenna bracket and a base station antenna system, wherein the base station antenna bracket is folded and connected by rotating a first folding component and a second folding component, wherein the end of the first folding component facing away from the second folding component is used to connect to a holding pole, and the end of the second folding component facing away from the first folding component is used to connect to the top of the antenna, and one end of the rotating frame is used to connect to the holding pole, and the other end of the rotating frame is used to connect to the bottom end of the antenna, and the bottom end of the antenna is connected to the holding pole through the rotating frame to achieve adjustment of the downward tilt angle of the antenna.

[0065] By arranging the telescopic mechanism on the first folding component, the transmission end of the telescopic mechanism is connected to the second folding component, and when the second folding component is driven by the telescopic mechanism to be unfolded or folded relative to the first folding component, the second folding component drives the top end of the antenna to move away from or close to the pole, so as to adjust the angle between the axis of the antenna along the length extension direction and the axis of the pole in the extension direction, thereby realizing automatic adjustment of the downtilt angle of the antenna, avoiding the operator from manually adjusting the downtilt angle of the antenna, and improving the adjustment efficiency and the operating safety of the operator.

[0066] Furthermore, by arranging a telescopic mechanism on the first folding component and connecting the transmission end of the telescopic mechanism to the second folding component, the first folding component and the second folding component can also be connected through the telescopic mechanism, a triangular stable structure can be formed between the first folding component, the second folding component and the telescopic mechanism, thereby improving the connection stability between the first folding component and the second folding component, thereby improving the structural stability of the folding mechanism, and achieving the structural stability of the base station bracket.

[0067] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0068] refer to Figure 1 and Figure 2 An embodiment of the present application provides a base station antenna bracket, which may include a folding frame 100, a rotating frame 300 and a telescopic mechanism 200.

[0069] The folding frame 100 may include a first folding component 110 and a second folding component 120 that are rotatably connected. The end of the first folding component 110 facing away from the second folding component 120 is used to connect to the holding pole 10, and the end of the second folding component 120 facing away from the first folding component 110 is used to connect to the top of the antenna 20.

[0070] refer to Figure 2 In some embodiments, the first folding component 110 and the second folding component 120 can be connected via a rotating shaft so that the second folding component 120 can rotate relative to the first folding component 110 around the axial direction of the rotating shaft to achieve folding and unfolding between the first folding component 110 and the second folding component 120.

[0071] One end of the rotating frame 300 is used to connect to the holding pole 10 , and the other end of the rotating frame 300 is used to connect to the bottom end of the antenna 20 . The bottom end of the antenna 20 is connected to the holding pole 10 through the rotating frame 300 .

[0072] It is understandable that Figure 1 Based on the orientation of the antenna 20 in the figure, in the height direction of the antenna 20, the top end of the antenna 20 is located above the bottom end of the antenna 20.

[0073] The embodiment of the present application provides a base station antenna bracket, which is folded and connected by rotating a first folding component 110 and a second folding component 120, the end of the first folding component 110 facing away from the second folding component 120 is used to connect to the holding pole 10, the end of the second folding component 120 facing away from the first folding component 110 is used to connect to the top of the antenna 20, and one end of the rotating frame 300 is used to connect to the holding pole 10, and the other end of the rotating frame 300 is used to connect to the bottom end of the antenna 20, and the bottom end of the antenna 20 is connected to the holding pole 10 through the rotating frame 300, so as to adjust the angle between the axis of the antenna 20 along the length extension direction and the axis of the holding pole 10 in the extension direction (such as Figure 1 , that is, to achieve the downtilt angle of antenna 20 (as shown in the angle α in FIG. Figure 1 Adjustment of the angle α as shown in FIG.

[0074] It can be understood that the angle between the axis of the antenna 20 along the length extension direction and the axis of the pole 10 along the extension direction can be the downtilt angle of the antenna 20.

[0075] refer to Figure 1 In some embodiments, the rotating frame 300 may include a first rotating member 310 and a second rotating member 320, wherein the first rotating member 310 is connected to the pole 10, and the second rotating member 320 is connected to the bottom end of the antenna 20. The first rotating member 310 and the second rotating member 320 are rotatably connected via a rotating shaft. When the first folding assembly 110 and the second folding assembly 120 in the folding frame 100 are folded or unfolded with each other, the first rotating member 310 and the second rotating member 320 rotate relative to the rotating shaft, so that the bottom end of the antenna 20 can rotate relative to the pole 10 through the rotating frame 300.

[0076] The telescopic mechanism 200 is disposed on the first folding assembly 110, and the transmission end 210 of the telescopic mechanism 200 is connected to the second folding assembly 120. When the telescopic mechanism 200 drives the second folding assembly 120 to unfold or fold relative to the first folding assembly 110, the second folding assembly 120 drives the top end away from or close to the pole 10, and the bottom end rotates relative to the pole 10 through the rotating frame 300 to adjust the angle between the axis of the antenna 20 along the length extension direction and the axis of the pole 10 in the extension direction.

[0077] It can be understood that, during the unfolding of the first folding assembly 110 and the second folding assembly 120 of the folding frame 100, the bottom end of the antenna 20 rotates relative to the pole 10, and the top end of the antenna 20 gradually moves away from the pole 10, so that the downtilt angle of the antenna 20 gradually increases. During the folding of the first folding assembly 110 and the second folding assembly 120 of the folding frame 100, the bottom end of the antenna 20 rotates relative to the pole 10, and the top end of the antenna 20 gradually moves closer to the pole 10, so that the downtilt angle of the antenna 20 gradually decreases.

[0078] In this way, by setting the telescopic mechanism 200 on the first folding component 110, the transmission end 210 of the telescopic mechanism 200 is connected to the second folding component 120, and when the second folding component 120 is driven by the telescopic mechanism 200 to expand or fold relative to the first folding component 110, the second folding component 120 drives the top of the antenna 20 away from or close to the pole 10, so as to adjust the angle between the axis of the antenna 20 along the length extension direction and the axis of the pole 10 in the extension direction, thereby realizing automatic adjustment of the downtilt angle of the antenna 20, avoiding the operator from manually adjusting the downtilt angle of the antenna 20, and improving the adjustment efficiency and the operating safety of the operator.

[0079] Furthermore, by arranging the telescopic mechanism 200 on the first folding component 110, and connecting the transmission end 210 of the telescopic mechanism 200 with the second folding component 120, so that the first folding component 110 and the second folding component 120 can also be connected through the telescopic mechanism 200, a triangular stable structure can be formed between the first folding component 110, the second folding component 120 and the telescopic mechanism 200, thereby improving the connection stability between the first folding component 110 and the second folding component 120, thereby improving the structural stability of the folding mechanism, and achieving the structural stability of the base station bracket.

[0080] refer to Figure 2 and Figure 3 In some embodiments, the telescopic mechanism 200 may include a driving assembly 220 and a telescopic assembly 230 that are connected to each other.

[0081] The telescopic component 230 has a transmission end 210 , and the corresponding telescopic component 230 also has a fixed end, and the transmission end 210 can be extended or contracted relative to the fixed end.

[0082] When the driving component 220 drives the telescopic component 230 to extend, the transmission end 210 drives the second folding back to rotate the first folding component 110 to unfold the folding frame 100, thereby increasing the angle between the axis of the antenna 20 along the length extension direction and the axis of the holding pole 10 along the extension direction.

[0083] When the driving component 220 drives the telescopic component 230 to retract, the transmission end 210 drives the second folding component 120 to rotate toward the first folding component 110 to fold the folding frame 100, thereby reducing the angle between the axis of the antenna 20 along the length extension direction and the axis of the pole 10 along the extension direction.

[0084] In this way, by setting the telescopic mechanism 200 as a driving component 220 and a telescopic component 230 that are connected to each other, and driving the telescopic component 230 to extend or contract through the driving component 220, it is possible to achieve automatic adjustment of the telescopic length of the telescopic component 230, thereby achieving automatic adjustment of the telescopic mechanism 200, and achieving automatic adjustment of the folding or unfolding of the folding frame 100.

[0085] Thus, in some embodiments, the telescopic assembly 230 may include a drive nut 231 , a lead screw 232 , and a telescopic rod 233 .

[0086] One end of the lead screw 232 is connected to the first folding assembly 110 , the driving nut 231 is rotatably connected to the lead screw 232 , the telescopic rod 233 is sleeved on the lead screw 232 and connected to the driving nut 231 , and one end of the telescopic rod 233 facing away from the driving nut 231 is connected to the second folding assembly 120 .

[0087] It should be noted that, although the lead screw 232 is connected to the first folding assembly 110, the connection state between the lead screw 232 and the first folding assembly 110 will not affect the rotation of the lead screw 232 around the axial direction of the lead screw 232. For example, one end of the lead screw 232 connected to the first folding assembly 110 has a rotating connection piece, and the lead screw 232 is connected to the first folding assembly 110 through the rotating connection piece, so that the lead screw 232 can be connected to the first folding assembly 110 and can rotate around the axis.

[0088] The driving assembly 220 is used to drive the lead screw 232 to rotate. The driving nut 231 moves along the axial direction of the lead screw 232 under the drive of the lead screw 232 and drives the telescopic rod 233 to move along the axial direction of the lead screw 232 .

[0089] In this way, by setting the telescopic component 230 as a driving nut 231, a screw 232 and a telescopic rod 233, the structure of the telescopic component 230 can be simplified, the manufacturing process of the telescopic component 230 can be simplified, and the manufacturing cost of the telescopic mechanism 200 can be reduced, thereby reducing the manufacturing and assembly cost of the base station antenna bracket.

[0090] refer to Figure 3 In some embodiments, the telescopic assembly 230 may further include a guide tube 234, which is sleeved on the outside of the lead screw 232, and the drive nut 231 is located in the guide tube 234, and the guide tube 234 is used to accommodate the telescopic rod 233 when the telescopic rod 233 is retracted.

[0091] In this way, by setting a guide tube 234 on the outside of the telescopic rod 233, the drive nut 231 and the telescopic rod 233 can be guided to move along the axial direction of the screw, thereby reducing the deviation of the drive nut 231 and the telescopic rod 233 during the axial movement along the screw 232, and improving the stability of the drive nut 231 and the telescopic rod 233 during the axial movement along the screw 232.

[0092] Furthermore, by providing a guide tube 234 on the outside of the telescopic rod 233, the lead screw 232 and the guide nut can be prevented from being damaged by the external environment, and the telescopic rod 233 can be accommodated when the telescopic rod 233 is retracted, thereby protecting the telescopic rod 233 in the retracted state.

[0093] refer to Figure 2 and Figure 3In some embodiments, the driving assembly 220 may include a driving structure 221, a transmission structure 222, and a control member. The driving structure 221 is disposed on the first folding assembly 110, and the transmission structure 222 is in transmission connection with the driving structure 221, and the transmission structure 222 is connected to the lead screw 232. The driving structure 221 drives the transmission structure 222 to rotate, so that the transmission structure 222 drives the lead screw 232 to rotate. The control member is connected to the driving structure 221 by signal, and the control member is used to control the start and stop of the driving structure 221.

[0094] In some embodiments, the control member can be connected to the drive structure 221 via a radio signal, so that the operator can remotely control the start and stop of the drive structure 221 through the control member. The control member can also control the driving direction of the drive structure 221 to achieve clockwise or counterclockwise rotation of the lead screw 232 through the drive structure 221 and the transmission structure 222 to achieve extension or contraction of the telescopic rod 233.

[0095] In this way, by remotely controlling the driving structure 221 through the control component, the telescopic process of the telescopic mechanism 200 can be further automatically adjusted, thereby avoiding the operator manually adjusting the folding frame 100, thereby improving the automation and practicality of the base station antenna bracket.

[0096] refer to Figure 2 and Figure 3 In some embodiments, the transmission structure 222 may include a first transmission tooth 2221 and a second transmission tooth 2222 , wherein the first transmission tooth 2221 is disposed on the driving structure 221 , and the second transmission tooth 2222 is disposed on the lead screw 232 , and the second transmission tooth 2222 is meshed with the first transmission tooth 2221 .

[0097] The driving structure 221 drives the first transmission teeth 2221 to rotate, so that the first transmission teeth 2221 drive the second transmission teeth 2222 to rotate, and the second transmission teeth 2222 drive the lead screw 232 to rotate.

[0098] In this way, the transmission structure 222 includes a first transmission tooth 2221 and a second transmission tooth 2222. Since gear transmission has good transmission accuracy and transmission stability, the transmission structure 222 is set to have a first transmission tooth 2221 and a second transmission tooth 2222, and the gear transmission is realized by the meshing connection of the first transmission tooth 2221 and the second transmission tooth 2222. This can improve the transmission accuracy and transmission stability of the transmission structure 222, thereby improving the power transmission accuracy of the drive component 220 and the working stability of the drive component 220.

[0099] refer to Figure 2 and Figure 3In some embodiments, the transmission structure 222 may further include a transmission shaft 2223 and a third transmission tooth 2224, the transmission shaft 2223 is arranged on the driving structure 221, the second transmission tooth 2222 is rotatably connected to the transmission shaft 2223, the third transmission tooth 2224 is arranged between the first transmission tooth 2221 and the second transmission tooth 2222, the first transmission tooth 2221 is meshed and connected to the second transmission tooth 2222 through the third transmission tooth 2224, and the third transmission tooth 2224 can rotate relative to the transmission shaft 2223.

[0100] In this way, by arranging the third transmission tooth 2224 between the second transmission tooth 2222 and the first transmission tooth 2221 , the torque on each transmission tooth can be distributed more evenly, and the load borne by each transmission tooth can be reduced, thereby improving the stability and durability of the transmission structure 222 .

[0101] In addition, by setting the third transmission tooth 2224 between the second transmission tooth 2222 and the first transmission tooth 2221, the transmission accuracy and reliability of the transmission structure 222 can be improved, the occurrence of errors and faults in the operation of the transmission structure 222 can be reduced, and the working efficiency and stability of the transmission structure 222 can be improved.

[0102] refer to Figure 2 and Figure 3 In some embodiments, the driving structure 221 may include a motor 2211 and an output shaft 2212, and the first transmission tooth 2221 is disposed on the output shaft 2212. When the motor 2211 drives the output shaft 2212 to rotate, the output shaft 2212 drives the first transmission tooth 2221 to rotate.

[0103] In this way, by configuring the driving structure 221 as a motor 2211 and an output shaft 2212 , the driving structure 221 can be simplified, the manufacturing cost of the driving structure 221 can be reduced, and the manufacturing process and manufacturing cost of the telescopic mechanism 200 can be simplified.
