Description

Technical Field

[0001] This utility model relates to the field of wireless testing equipment technology, and more specifically, to an antenna scanning frame and testing device. Background Technology

[0002] The scanning gantry in an antenna test system is primarily used to support and move the test probe. In large antenna test systems, the antenna scanning gantry plays a crucial role. To ensure the accuracy and reliability of the test, the antenna scanning gantry needs to meet multiple requirements.

[0003] First, there's the load-bearing capacity. To improve testing efficiency, testing systems typically have multiple test probes. Simultaneously, as the size of the device under test (DUT) continues to increase, the span of the antenna scanning frame also increases. The antenna scanning frame needs to be able to withstand the weight of the test probes, its own gravity, and the dynamic loads that may occur during testing to ensure the stability of the test probes and their supporting structure.

[0004] The deformation resistance of the scanning rig is also a crucial factor affecting test accuracy. For high-precision measurements, even minute deformations during scanning can lead to deviations in test results. Therefore, the scanning rig needs sufficient rigidity and stability to minimize deformation during the scanning process. This typically requires the scanning rig to be manufactured from high-strength and rigid materials and to undergo precision machining and assembly. Furthermore, regular calibration and maintenance of the scanning rig are necessary to ensure that its deformation remains within acceptable limits.

[0005] A common structure in existing multi-probe scanning frames uses multiple layers of steel plates with interlocking square tubes / I-beams as the main structural element. Test probes or guiding structures (such as guide rails) are then connected to one of these steel plates. To improve stability, the top of the main structure is fixed to the roof via connectors, providing upward tension and lateral stability. However, this type of sandwich steel plate structure results in a significant weight, making it difficult to balance lightweight design and structural rigidity over large spans.

[0039] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0040] Please see Figure 1 This application provides an antenna scanning frame 10, which can be used for wireless performance testing of devices under test (DUTs), such as vehicles, aircraft, or base stations. In other words, the antenna scanning device provided in this application can be applied to the wireless performance testing of large DUTs. Therefore, the overall size and weight of the antenna scanning device provided in this application are relatively large.

[0041] The antenna scanning frame 10 provided in this embodiment can improve the technical problem of difficulty in balancing lightweight and structural rigidity in the prior art.

[0042] In this embodiment, please refer to the following: Figure 1 , Figure 2 and Figure 3The antenna scanning frame 10 includes a support body 100, a test antenna assembly 200, a guide rail assembly 300, and a driving device 400. The support body 100 includes a frame 110 and multiple support rods 120; the multiple support rods 120 are all connected to the frame 110, and the multiple support rods form multiple tetrahedral structures 121, which are arranged along the extending direction of the frame 110. The test antenna assembly 200 is used to perform wireless performance testing on the device under test. The guide rail assembly 300 is connected to the frame 110, and the test antenna assembly 200 is connected to the arc-shaped guide rail assembly 300; the guide rail assembly 300 is used to slide relative to the frame 110 or the test antenna assembly 200, so that the test antenna assembly 200 slides relative to the frame 110 along an arc-shaped path. The driving device 400 is connected to the frame 110 or the guide rail assembly 300, and is connected to the test antenna assembly 200 to drive the test antenna assembly 200 to slide relative to the frame 110.

[0043] The frame 110 is generally arc-shaped, and the device under test (DUT) can typically be placed at the center of the arc path formed by the frame 110 for wireless performance testing. The guide rail assembly 300, used for sliding relative to the frame 110 or the test antenna assembly 200, refers to the fact that the guide rail assembly 300 has a fixed part and a sliding part, with the sliding part slidably mounted on the fixed part. In some configurations, the fixed part can be connected to the frame 110, and the sliding part can be connected to the test antenna assembly 200. Driving the test antenna assembly 200 via the drive device 400 allows the sliding part and the test antenna assembly 200 to slide together, thus achieving the sliding of the test antenna assembly 200 relative to the frame 110. In other configurations, the fixed part can be connected to the test antenna assembly 200, and the sliding part can be connected to the frame 110. In this case, the drive device 400 also drives the test antenna assembly 200, but the difference is that the test antenna assembly 200 and the fixed part move together to achieve the movement of the test antenna assembly 200 relative to the frame 110. In general, the test antenna can be moved relative to the frame 110.

[0044] As described above, in this antenna scanning frame 10, multiple support rods 120 are used for support on the frame 110, forming multiple tetrahedral structures 121. The tetrahedral structures 121 have strong structural stability, ensuring the overall reliable stress distribution of the frame 110. Based on this, the overall stability of the frame 110 can be enhanced from a structural perspective. Furthermore, compared to the sandwich steel plate form in the prior art, this frame 110 has advantages in weight, rigidity, and lateral stability. Therefore, the antenna scanning frame 10 provided by this utility model can improve the technical problem of balancing lightweight and structural rigidity in the prior art, while also addressing the issues of large self-weight deformation and poor lateral stability, thus improving testing accuracy.

[0045] Furthermore, the frame 110 includes a main body 111 and multiple mounting nodes 112; multiple support rods 120 are all connected to the main body 111, and together with the main body 111, form multiple tetrahedral structures 121; the main body 111 extends along an arc-shaped path, and the multiple mounting nodes 112 are connected at intervals to one side of the main body 111 near the center of the arc-shaped path, and the guide rail assembly 300 is connected to the multiple mounting nodes 112. By setting multiple mounting nodes 112 on the main body 111 for mounting the guide rail assembly 300 and the antenna scanning assembly, the high processing difficulty caused by directly mounting the guide structure onto the steel plate of the main body 111 in the prior art can be avoided.

[0046] It should be noted that in the prior art, the guide structure is usually installed directly onto the main body 111 steel plate by welding. However, welding deformation is prone to occur during the welding process, which can lead to improper installation of the guide structure and a significant reduction in test accuracy. However, in this embodiment, the above problems can be avoided by setting the installation node 112, which is beneficial to improving test accuracy.

[0047] It is worth noting that in some embodiments, the mounting node 112 can also be connected to the main body 111 by welding. In this case, even if the welding deformation of the mounting node 112 occurs, the mounting position of the guide rail assembly 300 on the mounting node 112 can be adjusted to ensure that the guide rail assembly 300 is installed in place, thereby ensuring that the test accuracy is not affected.

[0048] In this embodiment, the main body 111 includes multiple support rods 1111, each support rod 1111 including multiple sequentially connected rod segments, which are arc-shaped or straight. On the plane perpendicular to the support rods 1111, the lines connecting the multiple support rods 1111 form a polygon. Both ends of any support rod 120 are connected to two support rods 1111. The tetrahedral structure 121 formed by the multiple support rods 120 can also be regarded as arranged in the arc-shaped channel space enclosed by the multiple support rods 1111. By using the multiple tetrahedral structures 121 to support the multiple support rods 1111, the overall structural stability of the main body 111 can be improved.

[0049] When all segments are curved, multiple segments extend along curved paths; when all segments are straight, a single load-bearing member 1111 comprises multiple segments on the same polygon, which extend along the curved paths of the circumcircle corresponding to the polygon.

[0050] The polygon formed by the multiple support rods 1111 can be a rectangle, trapezoid, triangle, etc.

[0051] Preferably, on the plane of the vertical support rod 1111, the lines connecting multiple support rods 1111 form a triangle; one vertex of the triangle faces the center of the arc path of the support rod 1111. Among the polygons formed by multiple support rods 1111, the triangle structure is simpler and its stability meets the requirements. Furthermore, since the position corresponding to the vertex of the triangle is the intersection of the support rod 1111 and the support rod 120, the overall structural stability is high, making the support body 100 significantly superior to the existing sandwich steel plate structure in terms of weight, stiffness, and lateral stability.

[0052] It is worth noting that the support body 100 is constructed by connecting members such as the bearing rod 1111 and the support rod 120. Using the same materials, this support structure is lighter than the existing sandwich steel plate structure, and also offers better stability and rigidity. Therefore, by using the support body 100 provided in this embodiment, the technical problem of balancing lightweighting and structural rigidity in the prior art can be improved.

[0053] See also Figure 5 In some embodiments of this application, the guide rail assembly 300 includes a guide rail 310 and a plurality of sliders 320; the plurality of sliders 320 are slidably connected to the guide rail 310, and the plurality of sliders 320 are connected one-to-one with a plurality of mounting nodes 112; the test antenna assembly 200 is connected to the guide rail 310; the driving device 400 is connected to the main body 111, the driving device 400 is connected to the test antenna assembly 200 and is used to drive the test antenna assembly 200 and the guide rail 310 to slide relative to the plurality of sliders 320.

[0054] At this time, the drive device 400 is supported by the main body 111. When the drive device 400 outputs power, it transmits the power to the test antenna assembly 200. The test antenna assembly 200 drives the guide rail 310 to move relative to the multiple sliders 320, thus realizing the movement of the test antenna assembly 200 relative to the main body 111.

[0055] Optionally, please refer to the following: Figure 6 In some other embodiments of this application, the guide rail assembly 300 includes a guide rail 310, a guide rail mounting member 330, and a plurality of sliders 320; the guide rail mounting member 330 is fixedly connected to a plurality of mounting nodes 112; the guide rail 310 is connected to the guide rail mounting member 330, and the plurality of sliders 320 are slidably connected to the guide rail 310; the test antenna assembly 200 is connected to at least one slider 320; the driving device 400 is connected to the guide rail mounting member 330 or the main body 111, and the driving device 400 is connected to the test antenna assembly 200 and is used to drive the test antenna assembly 200 and the connected sliders 320 to slide relative to the guide rail 310.

[0056] At this time, the drive device 400 is supported by the guide rail mounting part 330 or the main body 111. When the drive device 400 outputs power, it transmits the power to the test antenna assembly 200. The test antenna assembly 200 drives the slider 320 to slide relative to the guide rail 310, thus realizing the movement of the test antenna assembly 200 relative to the main body 111.

[0057] It is worth noting that, Figure 5 and Figure 6 This is merely a schematic diagram of the connection relationship between the test antenna assembly 200, the guide rail assembly 300, and the support body 100. For ease of understanding, it is shown as extending along a straight line, and there are no restrictions on the actual shape and structure.

[0058] Optionally, in this embodiment, the test antenna assembly 200 includes an antenna mounting plate 210, an antenna bracket 220, and an antenna assembly 230. The antenna mounting plate 210 can be mounted on a guide rail 310 or a slider 320; the antenna bracket 220 is mounted on the antenna mounting plate 210, and the antenna assembly 230 is connected to the antenna bracket 220 in a corresponding manner. The antenna assembly 230 includes an antenna backplate 231 and a probe 233, the probe 233 being used to perform wireless testing.

[0059] It is worth noting that the guide rail assembly 300 can use the two methods described above to set the test antenna assembly 200 on the main body 111 in different forms.

[0060] For example, in Figure 5 When the slider 320 is directly connected to the mounting node 112, one or more antenna mounting plates 210 can be mounted on the guide rail 310, and one or more antenna components 230 on each antenna mounting plate 210 form a movable unit. In this case, one or more movable units can be mounted on the main body 111 to form a single moving probe group or multiple moving probe groups. Of course, some antenna mounting plates 210 can also be fixed relative to the main body 111 to form a partially fixed probe group; based on this, a combination of moving probe groups and fixed probe groups can also be formed.

[0061] For example, in Figure 6When the guide rail mounting component 330 is connected to the mounting node 112, the antenna mounting plate 210 is directly connected to the slider 320. For the multiple sliders 320 on the guide rail 310, different numbers of antenna mounting plates 210 can be set, and one or more antenna components 230 on each antenna mounting plate 210 also form a movable unit; thus, one or more movable units can be formed. Based on this, a single motion probe group or multiple motion probe groups can also be formed using this method. Similarly, when some antenna mounting plates 210 are fixed relative to the main body 111, a partially fixed probe group is also formed; similarly, a combination of motion probe groups and fixed probe groups can also be formed. This embodiment, compared to... Figure 5 The illustrated embodiment adds a guide rail mounting component 330.

[0062] In this embodiment, please refer to Figure 4 The mounting node 112 includes a base 1121, an adjusting member, and a mounting body 1122. The base 1121 is connected to the body 111, and the mounting body 1122 has at least one adjusting hole 102. The adjusting member passes through the adjusting hole 102 and is connected to the base 1121. The adjusting member is used to move relative to the base 1121 to adjust the position and / or attitude of the mounting body 1122 relative to the base 1121. Further, in this embodiment, the mounting body 1122 is also provided with a threaded hole 101, which allows bolts to pass through to connect the mounting body 1122 and the base 1121. The tightening of the bolt in the threaded hole 101 can also adjust the distance between the mounting body 1122 and the base 1121, that is, adjust the overall height of the mounting body 1122. In addition, the aforementioned adjustment components can adopt a set screw structure, that is, the mounting body 1122 can be adjusted by turning the set screw structure; with the cooperation of the bolt and set screw structure, the mounting body 1122 can be adjusted in multiple degrees of freedom, which is conducive to the installation of the guide rail assembly 300 and thus ensures that the test accuracy is not affected.

[0063] Furthermore, the mounting body 1122 includes an adjustment part 11222 and a mounting part 11221; an adjustment hole 102 is formed on the adjustment part 11222. The adjustment part 11222 and the mounting part 11221 are integrally formed.

[0064] In this embodiment, the mounting node 112 is provided at the connection between the support rod 120 and the main body 111. That is, the mounting node 112 is located at the junction of the support rod 120 and the bearing rod 1111. Since the connection between the support rod 120 and the bearing rod 1111 has good strength and stability, placing the mounting node 112 at the junction of the support rod 120 and the bearing rod 1111 ensures that the main stress point of the main body 111 is located at the junction of the support rod 120 and the bearing rod 1111, which helps to improve the problem of deformation of the main body 111 under stress and helps to ensure that the test accuracy is not affected.

[0065] Based on the antenna scanning frame 10 provided above, this embodiment also provides a testing device that uses the antenna scanning frame 10. Therefore, this testing device can also improve the technical problem of balancing lightweight design and structural rigidity in the prior art. The testing device may also include a platform for supporting or positioning the test piece.

[0066] In summary, in the antenna scanning frame 10 and testing device provided in this embodiment, the frame 110 is supported by multiple support rods 120, which form multiple tetrahedral structures 121. The tetrahedral structures 121 have strong structural stability, ensuring the overall reliability of the frame 110 under stress. Therefore, the overall stability of the frame 110 can be enhanced through structural characteristics. Furthermore, compared to the sandwich steel plate form in the prior art, this frame 110 has advantages in weight, rigidity, and lateral stability. Therefore, the antenna scanning frame 10 provided by this utility model can improve the technical problem of balancing lightweight and structural rigidity in the prior art, while also improving the problems of large self-weight deformation and poor lateral stability, which is beneficial to improving testing accuracy. Among the polygons formed by the multiple support rods 1111, the triangular structure is simpler and also meets the stability requirements. Meanwhile, since the apex of the triangle corresponds to the intersection of the load-bearing rod 1111 and the support rod 120, the overall structural stability is high, making the support body 100 significantly superior to existing sandwich steel plate structures in terms of weight, rigidity, and lateral stability. By setting multiple mounting nodes 112 on the body 111 for mounting the guide rail assembly 300 and the antenna scanning assembly, the high processing difficulty caused by directly mounting the guide structure onto the steel plate of the body 111 in existing technologies can be avoided.

[0067] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
