Technical Field

[0002] During the detection of the far-field antenna radiation performance of the base station antenna, the multi-beam antenna generally has horizontal beams of different degrees in the vertical plane, which is a very important antenna performance indicator.

[0003] However, the current antenna radiation performance detection system cannot accurately adjust the test tilt angle of the multi-beam antenna, which affects the accuracy of the antenna's horizontal beam performance test in the vertical plane and is not conducive to detecting the correctness of the antenna radiation pattern.

At this time, the work of installing the antenna to the radiation device is completed. The antenna is then installed to the detection position through the installation unit, and then the rotating parts can be rotated one by one according to the preset rotation angle, so that the rotating parts drive the antenna to perform horizontal beam tests on the vertical plane with different degrees.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0030] It should be noted that when an element is referred to as being "fixed on", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixed transmission connected" to another element, the two may be fixed in a detachable connection manner or in a non-detachable connection, as long as power transmission can be achieved, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0033] At present, in order to achieve the ideal measurement tilt angle of multi-beam antenna on the traditional test fixture, it is necessary to add an additional pad between the test fixture and the antenna. Generally, the pad can only adjust one angle. To test the horizontal beam performance of the vertical plane of multi-beam antennas with different degrees and to achieve different tilt angles, different pads need to be made. Therefore, the operation is cumbersome, time-consuming and labor-intensive, resulting in low efficiency of antenna detection and high detection costs.

[0034] In order to solve the above problems, Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, an auxiliary device is provided, including an installation unit 100, a rotating mechanism 200 and a positioning unit 300; the rotating mechanism 200 includes a fixing member 210 fixedly mounted on the installation unit 100, a rotating member 220 rotatable relative to the fixing member 210, and a locking assembly 230 for locking or releasing the rotating member 220, and the rotating member 220 is provided with a connecting portion 222; the positioning unit 300 is fixedly connected to the connecting portion 222, so that the positioning unit 300 can rotate with the rotating member 220, and the positioning unit 300 is provided with a fastening assembly for fixing the antenna housing, and a positioning portion 310 for positioning with the phase center of the antenna.

[0035] When the auxiliary device is used, the positioning part 310 is used to align and position with the phase center of the antenna, so that the phase center of the antenna overlaps with the physical center of the far field in two dimensions, and then the antenna is fixed to the positioning unit 300 by the fastening assembly, and the work of installing the antenna to the radiation device is completed. Then, the antenna is installed to the detection position through the installation unit 100, and then the locking assembly 230 is released, so that the rotating member 220 can rotate to reach the preset angle, and then the locking assembly 230 is used to lock the rotating member 220. In this way, the rotating member 220 can be rotated one by one according to the preset rotation angle, so that the rotating member 220 drives the antenna to test the horizontal beam of the vertical plane with different degrees. The auxiliary device can not only accurately adjust the test inclination angle of the multi-beam antenna, but also conveniently adjust the phase center of the antenna to overlap with the physical center of the far field in two dimensions, thereby ensuring the accuracy of the test of the antenna radiation index and facilitating the detection of the correctness of the antenna pattern.

[0036] It should be noted that the “fastening assembly” includes fastening technologies such as straps that can fix the antenna on the positioning unit 300.

[0037] The positioning portion 310 is a positioning mark, a positioning groove, a positioning protrusion, etc.

[0038] Based on any of the above embodiments, Figure 4 and Figure 5As shown, in one embodiment, the rotating member 220 is rotatably connected to the fixed member 210, and a boss 224 is provided between the rotating member 220 and the fixed member 210, and there are at least three bosses 224, which are arranged at intervals, and one of the bosses 224 is arranged on the outer peripheral side of the rotation center of the rotating member 220. In this way, the contact area between the rotating member 220 and the fixed member 210 is reduced by using the boss 224, which is conducive to reducing wear force and making the rotation of the rotating member 220 smoother. At the same time, it is conducive to reducing the manufacturing difficulty, and only the boss 224 and the area in contact with the boss 224 need to be polished.

[0039] Based on any of the above embodiments, Figure 1 and Figure 3 As shown, in one embodiment, the positioning unit 300 includes a first side plate 320 and a second side plate 330 that are spaced apart, and a connecting member 234 for connecting the first side plate 320 and the second side plate 330. The first side plate 320 and the second side plate 330 both protrude from the connecting plate 340 to form an escape space, and a positioning portion 310 is provided on the first side plate 320 or / and the second side plate 330. In this way, the antenna can be placed above the first side plate 320 and the second side plate 330, and through the escape space, the connecting plate 340 will not interfere with the movement of the antenna, so that the antenna can be moved so that the phase center of the antenna is aligned with the positioning portion 310.

[0040] Based on any of the above embodiments, in one embodiment, the locking assembly 230 is disposed between the rotating member 220 and the fixed member 210, and is used to lock the rotating member 220 on the fixed member 210, or after the rotating member 220 is released, the rotating member 220 can rotate relative to the fixed member 210. In this way, the locking assembly 230 is used to fix or release the rotating member 220 and the fixed member 210, so that the rotating member 220 can rotate or be fixed relative to the fixed member 210, which is convenient for setting a scale on the rotating member 210, and conveniently adjusting the inclination angle of the antenna according to a preset angle.

[0041] Furthermore, if Figure 5 and Figure 6 As shown, in one embodiment, the locking assembly 230 includes at least two locking parts 212 disposed on the fixed member 210, and a locking tongue 232 disposed on the rotating member 220, all the locking parts 212 are arranged at intervals along the outer circumference of the rotation center of the rotating member 220, and the locking tongue 232 and the locking parts 212 are detachably matched. In this way, the locking tongue 232 and the locking part 212 are matched to achieve the locking or release of the rotating member 220 and the fixed member 210.

[0042] There are many forms of cooperation between the locking tongue 232 and the locking portion 212, which can be implemented by any existing technology that can meet the use requirements.

[0043] Alternatively, if Figure 1 and Figure 6 As shown, in one embodiment, the lock tongue 232 is a lock hole opened on the fixing member 210, and the lock tongue 232 is a retractable lock column; when the lock column is in the first position, the lock column and the lock hole are locked and matched; when the lock column is in the second position, the lock column and the lock hole are staggered. In this way, the rotation member 220 and the fixing member 210 can be fixed by only needing the lock column to be in different telescopic positions, and then the test inclination angle of the antenna can be adjusted as needed, and then the lock column is used to lock, which is easy to implement and convenient to operate. Specifically, when the lock column is in the first position, the lock column and the lock hole are locked and matched, and the rotation member 220 is fixed on the fixing member 210; when the lock column is in the second position, the lock column and the lock hole are separated and staggered from each other, and the rotation member 220 can rotate relative to the fixing member 210, and then the test inclination angle of the antenna can be adjusted.

[0044] The locking column is an indexing pin, a hydraulic rod or a gas pressure rod.

[0045] Furthermore, if Figure 7 As shown, in one embodiment, the locking assembly 230 also includes a connecting member 234 fixed on the rotating member 220, and the lock column can be elastically contracted and arranged on the connecting member 234, one end of the lock column can extend out of the connecting member 234 and be inserted into the lock hole, and the other end of the lock column is provided with a limiting body 236, and the connecting member 234 is provided with a first limiting groove 202 and a second limiting groove 204 that cooperate with the limiting body 236, and the bottom wall of the second limiting groove 204 is arranged above the bottom wall of the first limiting groove 202; when the limiting body 236 cooperates with the first limiting groove 202, the lock column is in the first position; when the limiting body 236 cooperates with the second limiting groove 204, the lock column is in the second position. In this way, it is only necessary to pull the lock column so that when the limiting body 236 cooperates with the first limiting groove 202, the lock column is in the first position, and the lock column is locked and cooperated with the lock hole. At this time, the rotating member 220 is fixed on the fixed member 210; when the limiting body 236 cooperates with the second limiting groove 204, the lock column is in the second position, the lock column and the lock hole are separated and staggered from each other, and the rotating member 220 can rotate relative to the fixed member 210, thereby realizing the adjustment of the test tilt angle of the antenna.

[0046] Furthermore, if Figure 7 As shown, in one embodiment, the depth of the first limiting groove 202 is less than the depth of the second limiting groove 204, and the first limiting groove 202 and the second limiting groove 204 are staggered. In this way, the locking column is switched between the first position and the second position by staggered limitation, which is easy to operate.

[0047] It should be noted that the specific method of "the lock column can be elastically contracted and arranged on the connecting member 234" can be realized by existing technologies, such as the lock column is slidably connected to the connecting member 234, so that the lock column can move within a preset range. In this embodiment, the connecting member 234 is provided with a mounting through hole, and the lock column can be elastically contracted and arranged on the connecting member 234 through the mounting through hole.

[0048] Alternatively, if Figure 7 As shown, in one embodiment, the other end of the lock column is further provided with a pulling structure 238, which can be a pull ring, a handle, etc. It is convenient to pull the lock column so that the lock column can be switched between the first position and the second position, the operation is simple, and the locking is reliable.

[0049] Based on any of the above embodiments of the locking assembly, Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, all the locking parts 212 are evenly spaced as a group along the outer circumference of the rotation center of the rotating member 220, and the fixed member 210 is provided with two groups of locking parts 212 arranged opposite to each other, and one group of locking parts 212 corresponds to one locking tongue 232. In this way, the rotating member 220 is locked by using two locking assemblies 230, so that the fixing of the rotating member 220 is more secure. At the same time, all the locking parts 212 can be distributed along a preset angle for easy adjustment. If the locking parts 212 are arranged at an interval of 5°, and the corresponding locking parts 212 are set within the range of -45°-+45°, the rotating member 220 can be rotated to adjust the antenna to the desired angle in the radial direction.

[0050] Based on any of the above embodiments, Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, the mounting unit 100 is a frame structure, and the fixing member 210 is provided with a plug-in portion 214 that is plugged and fixedly matched with the side frame of the mounting unit 100. In this way, by utilizing the cooperation between the frame structure and the plug-in portion 214, it is convenient to fix the fixing member 210 on the mounting unit 100, and it is easy to adjust during this process so that the positioning portion 310 coincides with the physical center of the far field.

[0051] Furthermore, in one embodiment, the plug-in portion 214 includes a socket (not labeled) plugged into the side frame of the installation unit 100, and a fastener (not labeled) disposed on the side wall of the socket. In this way, the fixing member 210 can be inserted into the installation unit 100 through the socket, and after the position is checked, the fixing member 210 can be fixed with the fastener, which is simple to operate. The fastener is a bolt, a rivet, etc.

[0052] Of course, in other embodiments, the plug-in portion 214 is a snap-fit ​​structure that is sleeved with the frame structure.

[0053] like Figure 1 and Figure 8 As shown, in one embodiment, a system for detecting antenna radiation performance is also provided, including the auxiliary device in any of the above embodiments, and also including a holding pole 400, one end of the holding pole 400 is provided with a base 410, and the auxiliary device is fixed to the other end of the holding pole 400 through the installation unit 100.

[0054] The antenna radiation performance detection system adopts the auxiliary device in any of the above embodiments, uses the base 410 to fix the pole 400 at a preset position (such as a fixed object such as a roof or bottom surface), and uses the mounting unit 100 to fix the auxiliary device and the antenna fixed on the auxiliary device on the pole 400 together, which can accurately adjust the test tilt angle of the multi-beam antenna, and the phase center of the antenna overlaps with the physical center of the far field in two dimensions, ensuring the accuracy of the antenna radiation index test, which is conducive to detecting the correctness of the antenna pattern. Compared with the prior art, the operation is very convenient, greatly increasing the efficiency of detecting the antenna, and helping to reduce the cost of antenna detection.

[0055] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
