In addition, the meaning of "multiple" is two or more. In the specification and claims, "and / or" means at least one of the connected objects, and the character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0031] Combine the following Figure 1-Figure 4 The utility model describes an antenna coupling test device.

[0032] like Figure 1As shown, the antenna coupling test device provided by the utility model includes a first plane plate 1, a second plane plate 2 and a first positioning member 41. The first plane plate 1 and the second plane plate 2 are spaced apart in the vertical direction. A plurality of first positioning holes 11 are provided on the first plane plate 1, and a coupling plate 3 is provided on the second plane plate 2. The first positioning member 41 is provided on the first plane plate 1 and can be selectively matched with one or more first positioning holes 11, so that the first positioning member 41 is fixed relative to the first plane plate 1 on the plane where the first plane plate 1 is located. In the first direction and the second direction of the plane where the first plane plate 1 is located, the first positioning member 41 is suitable for limiting cooperation with the product under test 8, and the first direction and the second direction intersect. Among them, the product under test 8 can be an electronic device equipped with an antenna, such as a mobile phone, a learning machine, a tablet computer, etc.

[0033] The first direction and the second direction are two intersecting directions on the plane where the first plane plate 1 is located. For example, the first direction and the second direction are perpendicular to each other. Figure 1 and Figure 3 As shown, the first direction is the X direction, the second direction is the Y direction, and the vertical direction is the Z direction. The first positioning member 41 is limitedly matched with the product 8 to be tested in the first direction and the second direction, thereby positioning the product 8 to be tested in the first direction and the second direction.

[0034] The first plane plate 1 and the second plane plate 2 are arranged horizontally, and the first plane plate 1 is located above the second plane plate 2, or the first plane plate 1 is located below the second plane plate 2. The product under test 8 is arranged on the first plane plate 1, and the coupling plate 3 is arranged on the second plane plate 2, so that the product under test 8 and the coupling plate 3 are arranged at intervals in the vertical direction. Since the signal radiated by the antenna is spherically distributed, compared with the prior art in which the product under test is attached to the coupling plate, this embodiment can improve the test efficiency and is conducive to improving the consistency of the test.

[0035] Specifically, the first positioning member 41 is disposed on the first plane plate 1 and is detachably matched with any one or more first positioning holes 11. It is understandable that any one or more first positioning holes 11 can be selected to match with the first positioning member 41 to fix the position of the first positioning member 41 on the first plane plate 1; the position of the first positioning member 41 on the first plane plate 1 can also be adjusted by switching the first positioning hole 11 matched with the first positioning member 41, and then the positioning of the tested product 8 on the first plane plate 1 is achieved by the first positioning member 41 and the limit match of the tested product 8.

[0036] Among them, the first positioning member 41 is provided with a structure that can be inserted into the first positioning hole 11. Optionally, the first positioning member 41 includes a positioning portion and one or more positioning columns protruding from the positioning portion, and the positioning column is inserted into the first positioning hole 11. In the case where the first positioning member 41 cooperates with a first positioning hole 11 through a positioning column, the positioning column is non-rotatably arranged in the first positioning hole 11, for example, the first positioning hole 11 is a square hole, and the positioning column is a square column matching therewith. Optionally, the first positioning member 41 includes a positioning portion and a bolt, the positioning portion is used to limit the position of the measured product 8 in the first direction and the second direction, and the bolt is inserted into the first positioning hole 11 and locks the positioning portion and the first plane plate 1.

[0037] The antenna coupling test device provided by the utility model is characterized in that a first plane plate 1 and a second plane plate 2 are arranged at intervals in the vertical direction, a plurality of first positioning holes 11 are arranged on the first plane plate 1, a coupling plate 3 is arranged on the second plane plate 2, a first positioning member 41 and any one or more first positioning holes 11 on the first plane plate 1 can be detachably matched to fix the position of the first positioning member 41 on the plane where the first plane plate 1 is located, the first positioning member 41 is suitable for upper limit matching with the product to be tested 8 in the first direction and the second direction, when a certain model of product is tested for the first time, the relative position of the antenna 81 of the product to be tested 8 and the coupling plate 3 can be adjusted by switching the first positioning hole 11 matched with the first positioning member 41, the best test point can be found and the position of the corresponding first positioning hole 11 on the first plane plate 1 can be recorded, when the model of product is tested again later, the position of the product to be tested 8 can be quickly and accurately determined according to the recorded position of the first positioning hole 11, so as to avoid the need to determine the relative position of the product to be tested and the coupling plate through testing before each test of a different model of product, thereby improving the test efficiency, and being able to ensure the consistency of the relative position of the product to be tested of the same model and the coupling plate 3 in the test, which is conducive to improving the accuracy of the test.

[0038] like Figure 1 and Figure 2 As shown, the antenna coupling test device provided by the embodiment of the utility model further includes a test meter 7 and a coaxial cable 9, the first plane plate 1 is located above the second plane plate 2, and the coupling plate 3 is connected to the test meter 7 through the coaxial cable 9. In this way, the portion where the coaxial cable 9 is connected to the coupling plate 3 is located between the first plane plate 1 and the second plane plate 2, which can effectively avoid touching the coaxial cable 9 during the test and causing erroneous measurement.

[0039] Furthermore, the antenna coupling test device provided in this embodiment further includes a second positioning member 5. A plurality of second positioning holes 21 are provided on the second planar plate 2. The second positioning member 5 is disposed on the second planar plate 2 and is detachably matched with any one or more second positioning holes 21, so that the second positioning member 5 is fixed relative to the second planar plate 2 on the plane where the second planar plate 2 is located. The second positioning member 5 and the coupling plate 3 are matched for upper limit positioning in the first direction and the second direction.

[0040] Specifically, the second positioning member 5 is disposed on the second plane plate 2 and is detachably matched with any one or more second positioning holes 21. It is understandable that any one or more second positioning holes 21 can be selected to match with the second positioning member 5 to fix the position of the second positioning member 5 on the second plane plate 2; the position of the second positioning member 5 on the second plane plate 2 can also be adjusted by switching the second positioning holes 21 matched with the second positioning member 5, and then the coupling plate 3 is positioned on the second plane plate 2 through the limited matching of the second positioning member 5 and the coupling plate 3.

[0041] When using the antenna coupling test device, the relative position of the antenna 81 of the product under test 8 and the coupling plate 3 can be adjusted by switching the second positioning hole 21 that cooperates with the second positioning piece 5, or switching the first positioning hole 11 that cooperates with the first positioning piece 41, or simultaneously switching the first positioning hole 11 that cooperates with the first positioning piece 41 and the second positioning hole 21 that cooperates with the second positioning piece 5.

[0042] like Figure 4 As shown, in some embodiments of the utility model, the first positioning member 41 is provided with a positioning portion 411 and a matching portion 412. The positioning portion 411 has a first positioning edge 4111 and a second positioning edge 4112 perpendicular to each other. The first positioning edge 4111 and the second positioning edge 4112 are respectively suitable for limiting and matching with two adjacent sides of the product 8 to be tested, and the matching portion 412 is penetrated in the first positioning hole 11.

[0043] It can be understood that the product under test 8 has adjacent and mutually perpendicular outer contour edges. For example, the outer shape of the product under test 8 is a rectangular structure, and two adjacent and mutually perpendicular outer contour edges are respectively limitedly matched with the first positioning edge 4111 and the second positioning edge 4112 of the first positioning member 41.

[0044] Specifically, the first positioning edge 4111 extends along the first direction and cooperates with the upper limit position of the product 8 under test in the second direction, and the second positioning edge 4112 extends along the second direction and cooperates with the upper limit position of the product 8 under test in the first direction, thereby realizing positioning of the product 8 under test in the first direction and the second direction. Optionally, the positioning portion 411 has a first positioning portion and a second positioning portion, and the first positioning portion and the second positioning portion are vertically arranged to form an "L"-shaped structure.

[0045] It should be noted that the first positioning edge 4111 and the second positioning edge 4112 may not be perpendicular to each other, and the angle relationship between the two is set according to the outer contour shape of the actual measured product 8. For example, if the outer contour of the measured product 8 is a trapezoid, the first positioning edge 4111 and the second positioning edge 4112 may be set at an obtuse angle or an acute angle.

[0046] like Figure 4 As shown, in some embodiments of the present invention, the matching portion 412 includes a first positioning post 4121 and a second positioning post 4122. The first positioning post 4121 is inserted into the first positioning hole 11 corresponding to the first positioning edge 4111, and the second positioning post 4122 is inserted into the first positioning hole 11 corresponding to the second positioning edge 4112.

[0047] Specifically, the first positioning column 4121 is protruded from the first positioning portion, and the second positioning column 4122 is protruded from the second positioning portion. By cooperating with the first flat plate 1, the first positioning member 41 can be better fixed in the plane where the first flat plate 1 is located, so that the first positioning member 41 can more accurately position the product 8 under test in the first direction and the second direction.

[0048] The first positioning column 4121 and the second positioning column 4122 can both be circular column structures, and the first positioning hole 11 is correspondingly set as a circular hole, which is more convenient for processing the first flat plate 1. Of course, the first positioning column 4121 and the second positioning column 4122 can also be square column structures or main structures of other shapes, which is not specifically limited in this embodiment.

[0049] In the embodiment of the utility model, the first positioning member 41 and the second positioning member 5 have the same structure, and accordingly, the multiple first positioning holes 11 on the first plane plate 1 and the multiple second positioning holes 21 on the second plane plate 2 have the same size and arrangement. In this way, the first plane plate 1 and the second plane plate 2 can be used interchangeably, and the first positioning member 41 and the second positioning member 5 can be used interchangeably, which simplifies the structure and assembly of the antenna coupling test device.

[0050] It should be noted that the structures of the first positioning member 41 and the second positioning member 5 may also be different. The specific structures of the two can be set according to the structures of the actual product 8 to be tested and the coupling plate 3. As long as the first positioning member 41 can cooperate with the first positioning hole 11 to achieve position fixation and limit the position with the product 8 to be tested, and the second positioning member 5 can cooperate with the second positioning hole 21 to achieve position fixation and limit the position with the coupling plate 3, it will be fine.

[0051] like Figure 1 and Figure 2As shown, the antenna coupling test device provided in this embodiment further includes a support column 6, which is arranged in the vertical direction. The first plane plate 1 and the second plane plate 2 are connected by a plurality of support columns 6, and the distance between the first plane plate 1 and the second plane plate 2 in the vertical direction is adjustable.

[0052] It can be understood that the support column 6 is supported between the first plane plate 1 and the second plane plate 2 in the vertical direction, and at least one of the first plane plate 1 and the second plane plate 2 can adjust the height in the vertical direction on the support column 6. In this embodiment, the distance between the antenna 81 and the coupling plate 3 of the tested product 8 in the vertical direction can be adjusted according to different models of products, thereby further improving the test efficiency and consistency of the test.

[0053] Specifically, the support column 6 is provided with a plurality of third positioning holes 61 arranged in the vertical direction, and at least one of the first plane plate 1 and the second plane plate 2 is detachably connected to the support column 6 via a fixing member penetrating through the third positioning holes 61. The fixing member may be a detachable locking member such as a bolt or a screw.

[0054] The embodiment of the utility model provides a plurality of third positioning holes 61 arranged along the vertical direction on the support column 6, and utilizes a detachable connection with a fixing member penetrating the third positioning holes 61. The relative distance between the first plane plate 1 and the second plane plate 2 can be adjusted by switching the third positioning holes 61 that cooperate with the fixing member, thereby adjusting the relative distance between the measured product 8 and the coupling plate 3 in the vertical direction.

[0055] When the first plane plate 1 is provided with a plurality of first positioning holes 11 and the support column 6 is provided with a plurality of third positioning holes 61, when testing a certain model of product for the first time, the relative position of the antenna 81 of the tested product 8 and the coupling plate 3 can be adjusted by switching the first positioning hole 11 that cooperates with the first positioning member 41 and switching the third positioning hole 61 that cooperates with the fixing member, so as to find the best test point and record the position of the corresponding first positioning hole 11 on the first plane plate 1 and the position of the corresponding third positioning hole 61 on the support column 6. When testing the product of this model again later, the relative position of the tested product 8 and the coupling plate 3 can be quickly and accurately determined according to the recorded positions of the first positioning hole 11 and the third positioning hole 61.

[0056] It should be noted that the distance between the first plane plate 1 and the second plane plate 2 in the vertical direction is adjustable, and it can also be achieved in other ways. For example, the support column 6 is provided with a slide groove arranged in the vertical direction, and at least one of the first plane plate 1 and the second plane plate 2 is connected to the support column 6 by a bolt passing through the slide groove. The relative distance between the first plane plate 1 and the second plane plate 2 can be adjusted by adjusting the position of the bolt in the slide groove.

[0057] In the embodiment of the utility model, Figure 3As shown, a plurality of first positioning holes 11 are arranged at intervals in the first direction and the second direction; and / or a plurality of second positioning holes 21 are arranged at intervals in the first direction and the second direction.

[0058] It can be understood that coordinate systems regarding the first direction and the second direction are respectively formed on the plane where the first plane plate 1 is located and the plane where the second plane plate 2 is located, and the multiple first positioning holes 11 are equivalent to multiple coordinate points on the plane where the first plane plate 1 is located, and the multiple second positioning holes 21 are equivalent to multiple coordinate points on the plane where the second plane plate 2 is located.

[0059] Specifically, the plurality of first positioning holes 11 are arranged in a matrix, and the plurality of second positioning holes 21 are arranged in a matrix, that is, the plurality of first positioning holes 11 are arranged at equal intervals in the first direction and the second direction, and the plurality of second positioning holes 21 are arranged at equal intervals in the first direction and the second direction. The arrangement density of the plurality of first positioning holes 11 and the arrangement density of the plurality of second positioning holes 21 may be the same or different. Furthermore, the plurality of third positioning holes 61 are arranged at equal intervals in the vertical direction, so as to form a three-dimensional space coordinate scale for the product to be tested 8 and the coupling plate 3.

[0060] In this embodiment, the relative position of the tested product 8 and the coupling plate 3 in the horizontal direction can be determined according to the position of the first positioning hole 11 matched with the first positioning member 41 and / or the second positioning hole 21 matched with the second positioning member 5. The relative position of the tested product 8 and the coupling plate 3 in the vertical direction can be determined according to the position of the third positioning hole 61 matched with the fixing member. Therefore, as long as the positions of the first positioning hole 11, the second positioning hole 21 and the third positioning hole 61 corresponding to the best test point are recorded when testing a certain model of product for the first time, the relative position of the tested product 8 and the coupling plate 3 can be quickly determined when testing the product of this model next time.

[0061] The antenna coupling test device provided by the embodiment of the utility model also includes a third positioning member 42, and the third positioning member 42 is detachably matched with any one or more first positioning holes 11, so that the third positioning member 42 is fixed relative to the first plane plate 1 on the plane where the first plane plate 1 is located. The third positioning member 42 and the first positioning member 41 are suitable for being arranged on two opposite sides of the product under test 8, and are respectively matched with the two sides of the product under test 8 to limit the position, so that the product under test 8 is fixed relative to the first plane plate 1 in one direction of the plane where the first plane plate 1 is located, so that the positioning of the product under test 8 can be more stable. Among them, the structure of the third positioning member 42 and the structure of the first positioning member 41 can be arranged symmetrically with each other.

[0062] Optionally, when the size of the product 8 under test in the first direction is larger than the size in the second direction, the third positioning member 42 and the first positioning member 41 are suitable for being disposed on both sides of the second direction of the product 8 under test. When the size of the product 8 under test in the first direction is smaller than the size in the second direction, the third positioning member 42 and the first positioning member 41 are suitable for being disposed on both sides of the first direction of the product 8 under test.

[0063] The antenna coupling test device of this embodiment can be applied to multiple antenna tests, such as Figure 1 As shown, a product under test 8 is provided with a plurality of antennas 81, and the number of coupling plates 3 is the same as the number of antennas of the product under test 8. Each coupling plate 3 is positioned by a separate second positioning member 5. The plurality of coupling plates 3 are connected to the test instrument 7 by coaxial cables 9, respectively.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
