DETAILED DESCRIPTION

[0036] In order to make the above objectives, features and advantages of the present application more clear and easily understood, the detailed description of the specific embodiments of the present application is made below with reference to the accompanying drawings. In the following description, a lot of specific details are set forth in order to give a full and thorough understanding of the present application. However, the present application can be implemented in many different ways other than those described herein, and one of ordinary skill in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0037] Referring to Figures 1 to 4 , an embodiment of the present application provides a base assembly 10 of an exhaust pipe antenna, the base assembly 10 comprising a base plate 11, a fixing plate 12, a plurality of support arms 13 and a flange 14. The fixing plate 12 is arranged opposite to the base plate 11 with a spacing. The plurality of support arms 13 are connected between the base plate 11 and the fixing plate 12, and the opposite ends of the support arms 13 are detachably connected to the base plate 11 and the fixing plate 12, respectively. The plurality of support arms 13 are arranged in sequence with a spacing around the central axis of the fixing plate 12. The flange 14 comprises a plurality of clamping pieces 141 and a plurality of connecting plates 142. The plurality of clamping pieces 141 are arranged in one-to-one correspondence and detachably clamped on the plurality of support arms 13, and each connecting plate 142 is arranged in correspondence between two adjacent support arms 13, and the opposite sides of the connecting plate 142 are detachably clamped and connected to the two clamping pieces 141 arranged adjacently.

[0038] Specifically, the flange 14 is not limited to one, for example, a plurality, specifically, for example, two, three, four or more. The plurality of flanges 14 are arranged in sequence along the height direction of the support arm 13. The specific number of the flange 14 can be flexibly adjusted and arranged according to the number of the radio frequency connector. When the number of the radio frequency connector is larger, the number of the flange 14 is correspondingly increased, so that there is a large enough space and position to install a plurality of radio frequency connectors; on the contrary, when the number of the radio frequency connector is smaller, the number of the flange 14 is correspondingly reduced, for example, arranged as one, as long as the radio frequency connector and other devices can be installed.

[0039] It should be noted that the height direction of the support arm 13 is indicated by the double-headed arrow h in Figure 3 , that is, the direction parallel to the central axis of the fixing plate 12.

[0040] The base assembly 10 of the exhaust pipe antenna described above, each component of the base assembly 10 includes a base plate 11, a fixed plate 12, a plurality of support arms 13 and a plurality of flanges 14, which are connected in a detachable manner. Each component is designed for general use, has a high general-purpose rate, a simpler process and lower production cost. In addition, since the flange 14 includes a plurality of clamping pieces 141 and a plurality of connecting plates 142, the plurality of clamping pieces 141 are detachably clamped on the plurality of support arms 13 one by one, each connecting plate 142 is arranged between two adjacent support arms 13, and the opposite sides of the connecting plate 142 are detachably clamped and connected with two adjacent clamping pieces 141. In this way, the flange 14 does not need to be installed on the support arm 13 by special equipment and process, but can be manually installed on the support arm 13, and the installation flatness of the flange 14 on the support arm 13 can be adjusted. In addition, each component can be selected and assembled according to different requirements (such as diameter and height, etc.), easy to maintain, low cost. Each component of the base assembly 10 is assembled by fewer fasteners, flexible production, high assembly efficiency.

[0041] It should be noted that the detachable connection of the bottom end of the support arm 13 on the base plate 11 has many ways, such as plug-in cooperation, and again, for example, various fasteners such as screws, pins or rivets are connected with each other, which can be flexibly adjusted and set according to actual needs, and is not limited here.

[0042] Please refer to Figures 5 to 10 In one embodiment, the bottom end of the support arm 13 is provided with an insertion part 131, and the side of the base plate 11 facing the fixed plate 12 is provided with a plurality of insertion holes 111. The plurality of insertion holes 111 and the plurality of insertion parts 131 are arranged one by one and plug-in cooperate. In this way, the support arm 13 is plug-in cooperated with the insertion hole 111 on the base plate 11 through the insertion part 131 at the bottom end, which can realize quick assembly together.

[0043] Please refer to Figures 7 to 9In one embodiment, a first protrusion 1111 is arranged on the wall of the insertion hole 111, and the insertion portion 131 is provided with a recess 1311 corresponding to the position of the first protrusion 1111. The first protrusion 1111 extends into the recess 1311, and the recess 1311 can rotate relative to the first protrusion 1111. The first support surface 132 is arranged on the side of the support arm 13 away from the recess 1311, and the first limiting surface 112 is arranged on the base plate 11 and abuts against the first support surface 132. When the support arm 13 is rotated to a position perpendicular to the base plate 11, the first support surface 132 abuts against the first limiting surface 112. In this way, when the support arm 13 is rotated to the position, the support arm 13 is arranged perpendicularly to the base plate 11, and the first protrusion 1111 is located in the recess 1311, which can effectively prevent the insertion portion 131 of the support arm 13 from being separated from the insertion hole 111 along the axial direction of the base plate 11; in addition, the first support surface 132 abuts against the first limiting surface 112, which can ensure that the insertion portion 131 of the support arm 13 is stably arranged on the base plate 11.

[0044] In one embodiment, the first support surface 132 is perpendicular to the height direction of the support arm 13, and the first limiting surface 112 is perpendicular to the central axis of the base plate 11.

[0045] In one embodiment, the outer wall of the first protrusion 1111 includes a first arc surface and a second limiting surface 1112 connected to the first arc surface. The inner wall of the recess 1311 includes a second arc surface and a second support surface 1312 connected to the second arc surface. The first arc surface and the second arc surface are adapted to each other and rotate together. The second support surface 1312 abuts against the second limiting surface 1112. When the support arm 13 is rotated to a position perpendicular to the base plate 11, the second support surface 1312 abuts against the second limiting surface 1112. In this way, when the second support surface 1312 abuts against the second limiting surface 1112, a limiting effect is achieved, which can limit the rotation of the support arm 13 and make the support arm 13 perpendicular to the base plate 11; at the same time, the first support surface 132 abuts against the first limiting surface 112, which can form a self-locking effect in the height direction of the support arm 13, thereby preventing the support arm 13 from being separated from the base plate 11 along the axial direction of the base plate 11.

[0046] Referring to Figure 3 and Figure 4 In some embodiments, the base assembly 10 further includes a fixing member 15. The plurality of support arms 13 are detachably connected to the fixing member 15. In this way, the fixing member 15 can connect the support arms 13 together, thereby improving the rigidity and stability of the base assembly 10 as a whole. Alternatively, the number of fixing members 15 is not limited to one, and can be two, three, four or more. The plurality of fixing members 15 are arranged in sequence in the height direction of the support arm 13.

[0047] Referring to Figure 3、 Figure 4 and Figure 8 On the basis of the foregoing embodiments, the support arm 13 is provided with a second protrusion 133 on the side facing the central axis of the chassis 11, and each second protrusion 133 is detachably connected with the fixing member 15. In this way, each support arm 13 can be connected together, thereby improving the overall rigidity and structural stability of the base assembly 10. In addition, the second protrusion 133 provided on the support arm 13 can facilitate connection and fixation with the fixing member 15.

[0048] Please refer to Figure 3 、 Figure 4 and Figure 8 Specifically, the second protrusion 133 is provided with a first mounting hole 1331. The base assembly 10 further comprises a first connecting member 161 corresponding to the first mounting hole 1331. The first protrusion 1111 is detachably connected with the fixing member 15 through the first connecting member 161.

[0049] Optionally, the first connecting member 161 includes but is not limited to a pin, a rivet, a screw, etc.

[0050] Please refer to Figure 3 and Figure 4 In some embodiments, the top of the support arm 13 is provided with a second mounting hole. The base assembly 10 further comprises a second connecting member 162 corresponding to the second mounting hole. Optionally, the second connecting member 162 includes but is not limited to a pin, a rivet, a screw, etc. The top of the support arm 13 is detachably connected with the fixing disc 12 through the second connecting member 162. In this way, the fixing disc 12 is fixed to the three support arms 13 through the second connecting member 162 at the top of the support arm 13. The three support arms 13 have zero degrees of freedom, and are mutually restrained and jointly stressed.

[0051] Please refer to Figure 3 、 Figure 4 、 Figure 11 and Figure 12In one embodiment, the support arm 13 is provided with a first clamping groove 134 on one side away from the central axis of the chassis 11. The first clamping groove 134 is provided in correspondence with a clamping piece 141. Specifically, the clamping piece 141 includes a first clamping portion 1411 and two clamping arms 1412. The first clamping portion 1411 is clamped and matched with the first clamping groove 134. The two clamping arms 1412 are respectively connected to the opposite sides of the first clamping portion 1411. The two clamping arms 1412 cooperate with the first clamping portion 1411 to form a first insertion slot 1413, and the support arm 13 is correspondingly arranged inside the first insertion slot 1413. The clamping arm 1412 is correspondingly clamped and connected with a connecting plate 142. In this way, since the first clamping portion 1411 is clamped and matched with the first clamping groove 134, the support arm 13 is also synchronously arranged inside the first insertion slot 1413 and clamped by the two clamping arms 1412, so that the clamping piece 141 can be stably clamped and arranged on the support arm 13, and can prevent the clamping piece 141 from moving up and down along the height direction of the support arm 13. In addition, the clamping piece 141 and the support arm 13 are in a detachable clamping connection mode, so that the clamping piece 141 can be flexibly adjusted and replaced according to actual needs. In addition, the connecting plate 142 is clamped and arranged on the clamping arm 1412, so that the connecting plate 142 can be conveniently disassembled and assembled, and the connecting plate 142 can be flexibly adjusted and replaced according to actual needs, and a connecting plate 142 with a suitable size and shape can be selected.

[0052] Please refer to Figure 3 , Figure 4 , Figure 11 and Figure 12 In one embodiment, the clamping arm 1412 is provided with a second insertion slot 1414, and the inner wall of the second insertion slot 1414 is provided with a second clamping portion 1415. The connecting plate 142 is provided with a second clamping groove 1421, the connecting plate 142 is inserted into the second insertion slot 1414, and the second clamping portion 1415 is clamped and matched with the second clamping groove 1421. In this way, when the connecting plate 142 is inserted into the second insertion slot 1414, on the one hand, the connecting plate 142 is clamped and supported by the clamping arm 1412, so as to ensure the stability of the connecting plate 142; on the other hand, the second clamping groove 1421 on the connecting plate 142 is clamped and matched with the second clamping portion 1415, so as to ensure the connection stability of the connecting plate 142 and the clamping arm 1412.

[0053] Alternatively, the clamping arm 1412 includes but is not limited to a clamping structure made of a elastic material. In this way, when the corresponding connecting plate 142 is inserted into the second insertion slot 1414, the connecting plate 142 causes the second insertion slot 1414 to be opened up and down, the clamping arm 1412 correspondingly clamps the connecting plate 142, and at the same time, the second clamping portion 1415 is clamped into the inside of the second clamping groove 1421, so as to realize the positioning and fixing between the connecting plate 142 and the clamping arm 1412.

[0054] It can be understood that, since the flange 14 includes the clamping pieces 141 detachably clamped on the support arms 13, and the connecting plates 142 detachably installed on the clamping pieces 141. In this way, the number of the connecting plates 142 can be adaptively adjusted, and the installation positions of the connecting plates 142 in the height direction of the support arms 13 can be flexibly adjusted and set according to the actual requirements of the antenna input ports, which are not limited here.

[0055] Optionally, the connecting plate 142 is provided with a third mounting hole 1422 for mounting a radio frequency connector.

[0056] Please refer to Figures 1 to 3 , another embodiment of the present application provides an exhaust pipe antenna, the exhaust pipe antenna includes the base assembly 10 of the exhaust pipe antenna of any of the above embodiments, the exhaust pipe antenna further includes an antenna main body 20 and an antenna cover 30. The base assembly 10 and the antenna main body 20 are arranged inside the antenna cover 30, and the base assembly 10 is connected with the antenna main body 20 through the fixing disc 12.

[0057] The exhaust pipe antenna described above, each component of the base assembly 10 includes the base disc 11, the fixing disc 12, the plurality of support arms 13 and the plurality of flanges 14, adopts a detachable connection mode, each component is designed with high universality, the universality of each component is high, the process is simpler, and the production cost is lower. In addition, since the flange 14 includes a plurality of clamping pieces 141 and a plurality of connecting plates 142, the plurality of clamping pieces 141 are detachably clamped on the plurality of support arms 13 one by one, each connecting plate 142 is arranged between two adjacent support arms 13, and the opposite sides of the connecting plate 142 are detachably clamped and connected with two adjacent clamping pieces 141. In this way, the flange 14 does not need to be installed on the support arm 13 by using special equipment and process, but can be manually installed on the support arm 13, and the installation flatness of the flange 14 on the support arm 13 can be adaptively adjusted. In addition, each component can be selected and assembled according to different requirements (such as diameter and height), easy to maintain, and low cost. Each component of the base assembly 10 is assembled by using fewer fasteners, so that the production is flexible and the assembly efficiency is high.

[0058] In the related art, the exhaust pipe type antenna is generally composed of three sectors, that is, three reflectors are arranged in axial symmetry, and each sector is independently controlled by an electric control module. The electric control module is usually arranged on the back of the reflector, and the electric control module is connected with a phase shifter transmission mechanism. The electric control module drives the phase shifter transmission mechanism to work, so as to realize the adjustment of the phase. In this way, the internal layout space of the exhaust pipe antenna is more nervous, and the structure is more complex. At the same time, if the motor of the electric control module fails, the whole antenna needs to be disassembled for maintenance, which is inconvenient.

[0059] Please refer to Figure 2 , Figures 13 to 15In one embodiment, the exhaust pipe antenna further comprises an electric control module 40 and a phase shifter transmission mechanism. The electric control module 40 is detachably arranged on the base assembly 10, and the phase shifter transmission mechanism is connected with the antenna main body 20. The electric control module 40 comprises a first connector 41, and the phase shifter transmission mechanism comprises a second connector. The first connector 41 is detachably connected with the second connector. For example, the first connector 41 and the second connector are inserted and matched by means of a spline shaft. When the electric control module 40 drives the first connector 41 to rotate, the first connector 41 can correspondingly drive the second connector to rotate, the second connector drives the phase shifter transmission mechanism to work, and phase adjustment is realized. The electric control module 40 is detachably arranged on the base assembly 10, and the electric control module 40 and the phase shifter transmission mechanism are detachably connected through the first connector 41 and the second connector. Thus, when the electric control module 40 fails, the electric control module 40 can be disassembled and processed, and maintenance is convenient without the need to disassemble the whole antenna.

[0060] In one embodiment, the fixed disc 12 is provided with a fixed column 121, and the electric control module 40 is provided with a mounting portion 43 which is detachably connected with the fixed column 121.

[0061] Specifically, the fixed column 121 is, for example, two, and the mounting portion 43 is also two. The two mounting portions 43 are detachably connected with the two fixed columns 121 one by one. The exhaust pipe antenna further comprises a third connecting piece 50. The mounting portion 43 is fixedly arranged on the fixed column 121 through the third connecting piece 50. The third connecting piece 50 includes but is not limited to a pin, a rivet, a screw and the like. Specifically, the third connecting piece 50 is, for example, a loose screw which can prevent loosening and is stable in connection.

[0062] In some embodiments, the antenna main body 20 can be arranged as a directional antenna or a multi-sector antenna.

[0063] In this embodiment, the antenna main body 20 is arranged as a multi-sector antenna, and the electric control module 40 comprises a control mainboard and a plurality of motors 42. The plurality of motors 42 are electrically connected with the control mainboard. The first connector 41 is correspondingly a plurality of first connectors 41, each first connector 41 is arranged corresponding to the output shaft of each motor 42. The plurality of motors 42 are arranged corresponding to the plurality of phase shifter transmission mechanisms of the multi-sector antenna one by one.

[0064] The multi-sector antenna includes but is not limited to a dual-sector antenna, a triple-sector antenna or a quadruple-sector antenna and the like. In this embodiment, the multi-sector antenna is specifically taken as a triple-sector antenna as an example. The motor 42 is correspondingly arranged as three, and the first connector 41 and the second connector are both arranged as three. Each first connector 41 is inserted and matched with each second connector.
