Description

Technical Field

[0002] During the antenna test, it is necessary to constantly adjust the setting angle of the antenna under test relative to the signal receiving antenna in order to more comprehensively evaluate the performance of the antenna. Using mechanical structures for adjustment (such as gear and rack mechanisms) will cause wear of the mechanism after repeated use, resulting in reduced adjustment accuracy. Using the human eye to directly calibrate the angle is also prone to errors and requires high operation intensity. How to facilitate the adjustment of the angle of the antenna under test and improve test efficiency has become a problem that needs to be solved. Summary of the invention

[0081] Figure 1 Schematic diagram of the antenna positioning device of this embodiment. Figure 2 Schematic diagram of an exploded view of the antenna positioning device of this embodiment.

[0082] In some embodiments, Figure 1-Figure 2 As shown, the antenna positioning device in this embodiment includes a magnetic component 1, a fixing frame 2 and a mounting frame 3. The fixing frame 2 includes a rotating shaft 21. The mounting frame 3 includes an antenna mounting arm 31 and a shaft sleeve 32, and the mounting frame 3 is rotatably sleeved on the rotating shaft 21 through the shaft sleeve 32.

[0083] Specifically, the rotating shaft 21 is a cylinder, and the shaft sleeve 32 is a tubular structure. The shaft sleeve 32 is consistent with the length of the rotating shaft 21, and the shaft sleeve 32 and the rotating shaft 21 are clearance-matched.

[0084] Figure 3 2 is a schematic structural diagram of the fixing frame 2 and the mounting frame 3 of this embodiment. Figure 4 It is a partial schematic diagram of the fixing frame 2 and the mounting frame 3 of this embodiment. Figure 5 2 is a schematic cross-sectional view of the fixing frame 2 and the mounting frame 3 of this embodiment.

[0085] Further reference Figure 3-Figure 5 As shown, the magnetic assembly 1 includes a first magnetic member 11 disposed on the sleeve 32 and a second magnetic member 12 disposed on the rotating shaft 21. The materials of the first magnetic member 11 and the second magnetic member 12 include but are not limited to NdFeB strong magnets, permanent ferrite magnets, samarium cobalt magnets, aluminum nickel cobalt magnets or iron chromium cobalt magnets.

[0086] Figure 6 3 is an exploded schematic diagram of the fixing frame 2 and the mounting frame 3 of this embodiment. The magnetic assembly 1 of this embodiment further includes a third magnetic member 13 disposed on the shaft sleeve 32 and a fourth magnetic member 14 disposed on the connecting rod 22 .

[0087] Figure 7 1 is a schematic diagram of the structure of the first magnetic member 11 of this embodiment. The structure of the second magnetic member 12 can be configured to be the same as that of the first magnetic member 11, so as to facilitate the assembly of the antenna positioning device.

[0088] Figure 8-Figure 13 Schematic diagram of the position of the magnetic component 1 of this embodiment in different implementations.

[0089] Further reference Figure 8-Figure 10 As shown, in the rotation direction of the mounting bracket 3, the antenna mounting arm 31 has a plurality of test positions 6. When the antenna mounting arm 31 rotates to different test positions 6, the antenna A to be tested mounted on the antenna mounting arm 31 will face different directions.

[0090] Therefore, when the antenna A to be tested is at a different test position 6 , the relative position of the antenna A to be tested and the signal receiving antenna at a fixed position changes, so as to test the radiation performance of the antenna A to be tested.

[0091] In some embodiments, Figure 8-Figure 12 As shown, the magnetic assembly 1 is configured such that the number of first magnetic members 11 is multiple, and the multiple first magnetic members 11 are spaced apart along the circumference of the sleeve 32, and the number of second magnetic members 12 is at least one. In this embodiment, when the number of first magnetic members 11 is multiple, the number of second magnetic members 12 is one or multiple spaced apart.

[0092] In other embodiments, Figure 8-Figure 11 As shown, the magnetic assembly 1 is configured such that the number of the second magnetic components 12 is multiple, and the multiple second magnetic components 12 are spaced apart along the circumference of the rotating shaft 21, and the number of the first magnetic components 11 is at least one. In this embodiment, when the number of the second magnetic components 12 is multiple, the number of the first magnetic components 11 is one or multiple spaced apart.

[0093] In some embodiments, Figure 8-Figure 12 As shown, the magnetic assembly 1 is also configured so that when the antenna mounting arm 31 is in any test position 6, at least one first magnetic member 11 and at least one second magnetic member 12 attract each other to a relative position. Thus, the first magnetic member 11 and the second magnetic member 12 are used to position the mounting frame 3 by the fixing frame 2, and the position accuracy of the antenna A to be tested is maintained.

[0094] In some embodiments, Fig.13 As shown, the magnetic assembly 1 is also configured so that when the antenna mounting arm 31 is located between two adjacent test positions 6, the first magnetic member 11 is staggered from all the second magnetic members 12. Thus, the operator can continuously rotate the mounting frame 3 to adjust the setting direction of the antenna A to be tested, thereby preventing the magnetic force of the magnetic assembly 1 from affecting the rotation of the antenna mounting arm 31.

[0095] In summary, the antenna positioning device in this embodiment rotatably connects the sleeve 32 to the rotating shaft 21, and uses the antenna mounting arm 31 to mount the antenna A to be tested, so that the operator can adjust the setting angle of the antenna A to be tested by rotating the mounting frame 3. Therefore, on the one hand, the first magnetic part 11 is set on the sleeve 32, and the second magnetic part 12 is set on the rotating shaft 21. When the antenna mounting arm 31 is rotated to the test position 6, the first magnetic part 11 can just attract the second magnetic part 12 to accurately locate the relative position of the fixing frame 2 and the mounting frame 3. On the other hand, when the antenna mounting arm 31 is staggered with the test position 6, the first magnetic part 11 is also staggered with the second magnetic part 12. When the operator rotates the antenna mounting arm 31, he can feel the change of magnetic attraction. Therefore, by the magnitude of the magnetic attraction, it is judged whether the current antenna A to be tested is in the test position 6.

[0096] In some embodiments, Figure 7-Figure 8As shown, the first magnetic member 11 and the second magnetic member 12 both include a first magnetic pole 41 and a second magnetic pole 42 with opposite polarities. The first magnetic pole 41 of the first magnetic member 11 is arranged close to the rotating shaft 21 , and the second magnetic pole 42 of the second magnetic member 12 is arranged close to the sleeve 32 .

[0097] Optionally, the first magnetic pole 41 is an N pole, and the second magnetic pole 42 is an S pole. The arrangement positions of the first magnetic member 11 and the second magnetic member 12 in this embodiment can ensure that the magnetic assembly 1 provides sufficient magnetic attraction.

[0098] In some embodiments, Figure 7-Figure 8 As shown, the first magnetic member 11 and the second magnetic member 12 are both strip-shaped structures, the two ends of the strip-shaped structures are the first magnetic pole 41 and the second magnetic pole 42 respectively, and the length direction of the strip-shaped structure is arranged along the radial direction of the rotating shaft 21 .

[0099] This helps to arrange the first magnetic part 11 and the second magnetic part 12, especially when the number of the first magnetic part 11 and the second magnetic part 12 is large, so that the magnetic field of the magnetic component 1 can be effectively distributed, ensuring that when the antenna mounting arm 31 is in the test position 6, the first magnetic part 11 and the second magnetic part 12 attract each other, and when the antenna mounting arm 31 is in a position offset from the test position 6, the first magnetic part 11 and the second magnetic part 12 can also be offset from each other.

[0100] In some embodiments, Figure 4 and Figure 8 As shown, the sleeve 32 is loosely matched with the shaft 21. The end surface of the first magnetic pole 41 of the first magnetic member 11 is exposed to the inner wall of the sleeve 32, and the end surface of the second magnetic pole 42 of the second magnetic member 12 is exposed to the outer wall of the shaft 21. As a result, the magnetic attraction between the first magnetic member 11 and the second magnetic member 12 is increased, which helps the relative rotation of the shaft 21 and the sleeve 32 and reduces the resistance between the two.

[0101] In some embodiments, Figure 7 As shown, the strip structure includes a fixing body 43, and in the extension direction of the strip structure, the cross-sectional area of ​​the fixing body 43 is larger than the cross-sectional area of ​​the first magnetic pole 41 and the second magnetic pole 42. Thus, the magnetic assembly 1 can be stably connected to the fixing frame 2 and the mounting frame 3, avoiding the mutual attraction between the first magnetic member 11 and the second magnetic member 12, which causes the first magnetic member 11 and the second magnetic member 12 to become loose.

[0102] In some embodiments, Figure 4-Figure 5 As shown, the fixing frame 2 further includes a connecting rod 22, and the rotating shaft 21 is protruded from the side of the connecting rod 22. The shaft sleeve 32 and the rotating shaft 21 both have a plurality of fixing grooves 51, and the plurality of fixing grooves 51 are respectively located at one end of the shaft sleeve 32 and the rotating shaft 21 away from the connecting rod 22, and the first magnetic member 11 and the second magnetic member 12 are arranged in the fixing grooves 51.

[0103] Specifically, the fixing groove 51 on the sleeve 32 and the rotating shaft 21 has a notch, and the fixing groove 51 is open to the side away from the connecting rod 22 through the notch, so that the operator can insert the first magnetic component 11 and the second magnetic component 12 into the fixing groove 51 from the ends of the sleeve 32 and the rotating shaft 21, thereby simplifying the installation method of the magnetic assembly 1.

[0104] In other embodiments, Figure 1-Figure 4 As shown, the rotating shaft 21 and the sleeve 32 are both injection molded parts. At the same time, at least part of the first magnetic part 11 and at least part of the second magnetic part 12 are arranged in the injection molded part. The magnetic component 1 in this embodiment is arranged inside the injection molded part as an insert, so that the structure of the antenna positioning device is more compact, especially when the size of the first magnetic part 11 and the second magnetic part 12 is small, the installation steps of the magnetic component 1 can be simplified.

[0105] In some embodiments, Figure 3 As shown, the connecting rod 22 has a support surface 221, the rotating shaft 21 is protruding from the support surface 221, and the end of the sleeve 32 away from the fixing groove 51 abuts against the support surface 221. The rotating shaft 21 in this embodiment stands upright on the top of the connecting rod 22, and the support surface 221 is used to carry the sleeve 32 so that it can rotate on the support surface 221.

[0106] In some embodiments, Figure 3 As shown, there are multiple first magnetic members 11, which form multiple groups of first magnetic members 11, and the multiple groups of first magnetic members 11 are distributed along the axial direction of the sleeve 32. There are multiple second magnetic members 12, which form multiple groups of second magnetic members 12 corresponding to the multiple groups of first magnetic members 11.

[0107] Therefore, by arranging multiple groups of first magnetic members 11 and multiple groups of second magnetic members 12 in the mounting frame 3 and the fixing frame 2 , the internal spaces of the two can be fully utilized, while greatly increasing the magnetic attraction of the magnetic assembly 1 .

[0108] In some embodiments, Figure 3 As shown, the fixing frame 2 further includes a connecting rod 22, the connecting rod 22 has a supporting surface 221, and the rotating shaft 21 is protruded from the supporting surface 221. Figure 6 As shown, the magnetic assembly 1 further includes a plurality of third magnetic members 13 disposed at the end of the sleeve 32 and a plurality of fourth magnetic members 14 disposed at the connecting rod 22 .

[0109] The shaft sleeve 32 is in contact with the support surface 221 and rotates relatively, at least one third magnetic member 13 and at least one fourth magnetic member 14 are attracted to each other to relative positions, at least one first magnetic member 11 and at least one second magnetic member 12 are arranged relatively. The third magnetic member 13 and all the fourth magnetic members 14 are staggered, and the first magnetic member 11 and all the second magnetic members 12 are staggered.

[0110] In this embodiment, the number and position of the third magnetic member 13 and the fourth magnetic member 14 can be respectively set corresponding to the first magnetic member 11 and the second magnetic member 12. The third magnetic member 13 and the fourth magnetic member 14 can increase the magnetic attraction of the magnetic assembly 1. In addition, when the sleeve 32 and the rotating shaft 21 are connected to each other, the third magnetic member 13 and the fourth magnetic member 14 can ensure the quick connection between the two, so that the end of the sleeve 32 and the support surface 221 abut against each other.

[0111] In some embodiments, Figure 1-Figure 8 As shown, the material of the mounting frame 3 and the fixing frame 2 is configured to be at least one of plastic, rubber or plastic (which can be a plastic material with low dielectric loss). The antenna mounting arm 31 extends from the outer side of the sleeve 32. The first magnetic member 11 is arranged on the side of the sleeve 32 away from the antenna mounting arm 31.

[0112] Therefore, on the one hand, the fixing frame 2 and the mounting frame 3 can be made by injection molding. On the other hand, it is avoided that the fixing frame 2 and the mounting frame 3 are made of metal materials, thereby preventing interference with the performance test of the antenna A to be tested. On the other hand, it can also reduce the impact of the magnetic component 1 on the test of the antenna A to be tested.

[0113] Furthermore, the material of the magnetic component 1 is ferrite. For example, the material of the magnetic component 1 can be configured as permanent ferrite. The resistivity of the permanent ferrite is much greater than that of most metal and alloy magnetic materials, and it has a higher magnetic permeability at high frequencies. Therefore, the use of permanent ferrite can reduce the impact on the test results.

[0114] In some embodiments, Figure 8 and Fig. 9 As shown, the number of the first magnetic members 11 and the number of the second magnetic members 12 are both multiple and the same. When the antenna mounting arm 31 is located at one test position 6, the multiple first magnetic members 11 correspond one-to-one with the multiple second magnetic members 12. That is, in this embodiment, when the antenna mounting arm 31 is located at other test positions 6, some of the first magnetic members 11 correspond one-to-one with some of the second magnetic members 12.

[0115] It is easy to understand that when the operator rotates the antenna mounting arm 31, for example, Figure 8 Status turns to Fig. 9The magnetic attraction generated by the magnetic component 1 will gradually decrease. This can remind the operator of the current rotation range of the antenna mounting arm 31. Furthermore, when the operator resets the antenna A to be tested, the change in magnetic attraction can also be used to determine whether the antenna A to be tested is in the initial position ( Figure 8 shown).

[0116] In some embodiments, Fig.11 and Fig.12 As shown, there are multiple first magnetic members 11 and the number of the first magnetic members 11 is greater than the number of the second magnetic members 12. The antenna mounting arm 31 rotates from one test position 6 to another test position 6, and the first magnetic members 11 correspond to different second magnetic members 12 respectively.

[0117] It is easy to understand that when the antenna positioning device is in Figure 8 In the state, the magnetic component 1 is far away from the antenna A to be tested. However, when the sleeve 32 is rotated 90 degrees clockwise (such as Fig.10 As shown), the distance between the first magnetic component 11 and the antenna A to be tested remains unchanged, but most of the second magnetic components 12 will be close to the antenna A to be tested, so that the influence of the magnetic component 1 on the antenna A to be tested changes with the angle of the antenna A to be tested, thereby affecting the detection of the antenna A to be tested.

[0118] To this end, the number of the second magnetic members 12 in this embodiment is configured to be relatively small, for example, the number of the second magnetic members 12 may be 1, 2, 3 or 4. The number of the second magnetic members 12 may be 13. Thus, even when the antenna mounting arm 31 is rotated to the 90° position, the second magnetic member 12 can still maintain a relatively long distance from the antenna A to be tested.

[0119] In some embodiments, Figure 8-Figure 11 As shown, the spacing between the first magnetic members 11 is the same, and the spacing between the second magnetic members 12 is the same and consistent with the spacing between the first magnetic members 11. Thus, the antenna mounting arm 31 can have a large number of test positions 6 with close spacing.

[0120] Specifically, in the circumferential direction of the rotating shaft 21 , the angle between two adjacent first magnetic members 11 is 15 degrees, and the angle between two adjacent second magnetic members 12 is also 15 degrees.

[0121] Thus, the angle of the antenna mounting arm 31 can be adjusted evenly, which helps the antenna positioning device to adjust the antenna A to be tested at multiple angles. Fig.13As shown in FIG. 1 , the magnetic force of the two adjacent second magnetic members 12 can still act on the first magnetic member 11 to drive the antenna mounting arm 31 to rotate. The antenna mounting arm 31 is made to rotate clockwise or counterclockwise to a state corresponding to one of the first magnetic members 11, so as to prevent the antenna mounting arm 31 from staying between the two test positions 6.

[0122] In some embodiments, Figure 1-Figure 2 As shown, the antenna positioning device further includes a stopper 7. The stopper 7 has a stopper surface 71, and the stopper 7 is detachably connected to the end of the rotating shaft 21, and the stopper surface 71 is arranged opposite to the end surface of the shaft sleeve 32. In this embodiment, the stopper 7 is used to prevent the antenna mounting arm 31 from moving along the axial direction of the rotating shaft 21 during rotation.

[0123] In some embodiments, Figure 1-Figure 5 As shown, a threaded hole 211 is formed on the end surface of the rotating shaft 21 , and the limiting member 7 includes a stud 72 threadedly connected to the threaded hole 211 , and the length of the stud 72 is less than the depth of the threaded hole 211 .

[0124] In an optional implementation, the antenna positioning device in this embodiment can be used in the following manner: First, the antenna A to be tested is mounted on the antenna mounting arm 31, and the sleeve 32 is sleeved on the rotating shaft 21. Secondly, the stud 72 is screwed into the threaded hole 211, and it is ensured that there is a gap between the limit surface 71 and the end surface of the sleeve 32. Again, after adjusting the angle of the antenna mounting arm 31 to the first test position 6, the limiter 7 is tightened so that the limit surface 71 abuts against the sleeve 32, thereby preventing the sleeve 32 and the rotating shaft 21 from rotating relative to each other. Again, the antenna A to be tested at the first test position 6 is tested once. Again, the limiter 7 is loosened so that there is a gap between the limit surface 71 and the end surface of the sleeve 32, and the antenna mounting arm 31 is adjusted to the second test position 6, and the limiter 7 is tightened again. Finally, after the second test is completed, the limiter 7 is unscrewed from the threaded hole 211, and the mounting bracket 3 is removed.

[0125] In some embodiments, Figure 6 As shown, the support surface 221 has an angle mark 8, and in the axial direction of the rotating shaft 21, the antenna mounting arm 31 overlaps with a portion of the angle mark 8. When the operator rotates the antenna mounting arm 31, by observing the corresponding position of the antenna mounting arm 31 on the angle mark 8, the angle of the antenna mounting arm 31 can be quickly adjusted in coordination with the magnetic component 1.

[0126] In some embodiments, Figure 1-Figure 3 As shown, a substrate connection hole 311 is formed at the end of the antenna mounting arm 31 away from the shaft sleeve 32 , and the axial direction of the substrate connection hole 311 is tangent to the circumferential direction of the shaft sleeve 32 .

[0127] Specifically, the antenna A to be tested in this embodiment is a patch antenna, and a through hole connected to the substrate connection hole 311 is provided on the patch antenna. When the antenna A to be tested is installed in the substrate connection hole 311, the thickness direction of the patch antenna is perpendicular to the rotation direction of the antenna mounting arm 31. This helps to detect the spatial distribution of the beam in a direction perpendicular to the patch antenna substrate.

[0128] Fig.14 Schematic diagram of the structure of the antenna testing system of this embodiment.

[0129] In some embodiments, Fig.14 As shown, the antenna positioning device in the above embodiment can be applied to an antenna test system. The antenna test system also includes a shielding box 9. The antenna positioning device is arranged inside the shielding box 9 and is fixedly connected to the shielding box 9 through a fixing frame 2.

[0130] Specifically, Figure 2 As shown, the fixing frame 2 also includes a connecting plate 23 connected to the connecting rod 22. The connecting plate 23 is fixedly connected to the inner wall of the shielding box 9. The installation steps of the antenna A to be tested are simplified by the detachable mounting frame 3. The signal receiving antenna is arranged on the outer side of the shielding box 9, and the signal receiving antenna is connected to the shielding box 9 through the side opening (such as Fig. 9 ) is arranged opposite to the antenna A to be tested.

[0131] In summary, the antenna test system in this embodiment rotatably connects the sleeve 32 of the antenna positioning device to the rotating shaft 21, and uses the antenna mounting arm 31 to install the antenna A to be tested, so that the operator can adjust the setting angle of the antenna A to be tested by rotating the mounting frame 3. Therefore, on the one hand, the first magnetic part 11 is set on the sleeve 32, and the second magnetic part 12 is set on the rotating shaft 21. When the antenna mounting arm 31 is rotated to the test position 6, the first magnetic part 11 can just attract the second magnetic part 12 to accurately locate the relative position of the fixing frame 2 and the mounting frame 3. On the other hand, when the antenna mounting arm 31 is staggered with the test position 6, the first magnetic part 11 is also staggered with the second magnetic part 12. When the operator rotates the antenna mounting arm 31, he can feel the change of magnetic attraction. Therefore, by the magnitude of the magnetic attraction, it is judged whether the current antenna A to be tested is in the test position 6.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
