If there is a description of "first", "second", etc., it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0022] In the description of the present invention, unless otherwise clearly defined, words such as “setting”, “installation” and “connection” should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above words in the present invention based on the specific content of the technical solution.

[0023] In the following embodiments, Figure 1 and Figure 2 As shown, it can be understood that the components described below are provided with absorbing cotton 400 at least in the direction toward the electronic product when used for antenna testing. For the sake of convenience in display, the absorbing cotton 400 has been hidden in the drawings related to the following embodiments.

[0024] Please refer to Figure 1 On the one hand, an embodiment of the present invention provides an antenna testing mechanism for testing the antenna performance of an electronic product, including a test antenna module 100 and a clamping module 200. The test antenna module 100 includes a first driving component 110 and a test antenna 120. The test antenna 120 can reciprocate along a first direction (Z direction in the figure) driven by the first driving component 110; the clamping module 200 includes a second driving component 210 and a fixture component 220. The fixture component 220 is used to clamp the electronic product. The fixture component 220 is located below the test antenna 120 along the first direction and can move relative to the test antenna 120 under the drive of the second driving component 210.

[0025] According to the antenna testing mechanism of the embodiment of the present invention, the electronic product is installed in the fixture assembly 220 and moves under the drive of the second driving assembly 210 until the antenna of the electronic product corresponds to the test antenna 120. The test antenna 120 reciprocates along the first direction under the action of the first driving assembly 110 and sends a test signal to the electronic product. The antenna of the electronic product receives the test signal and converts it into an evaluable parameter.

[0026] It should be noted that in the related art, a solution of setting up an antenna detection mechanism in a shielding box is usually adopted to detect the antenna performance of electronic products. The test antenna 120 on the antenna detection mechanism can adjust the coupling position with the electronic product to ensure the detection accuracy. However, due to the complexity of the related mechanisms for realizing the movement of the test antenna 120, the test antenna 120 cannot move back and forth at a high frequency. Therefore, usually only static detection of electronic products can be performed, and the antenna performance test of electronic products under the condition of reciprocating movement of the test antenna 120 cannot be completed.

[0027] According to the antenna testing mechanism of the embodiment of the present invention, by setting the second driving component 210 for adjusting the relative position of the test antenna 120 and the electronic product on the clamping module 200, there is no need to set a complex position adjustment mechanism on the test antenna 120. The test antenna 120 can achieve high-precision and high-frequency reciprocating motion under the drive of the first driving component 110, thereby realizing the antenna performance test of the antenna of the electronic product under special detection requirements, such as the reciprocating motion of the test antenna 120, and effectively expanding the types of test methods that can be adapted by the antenna testing mechanism.

[0028] In this embodiment, the first driving component 110 can drive the test antenna 120 to reciprocate at a frequency of 1 Hz. Of course, in other embodiments, the test frequency can be adjusted based on actual test requirements.

[0029] In this embodiment, the first driving component 110 may include a slide module, and the slide is driven to move by a high-precision motor; of course, the first driving component 110 may also include a screw module, a cylinder, an oil cylinder, etc.

[0030] In this embodiment, the first drive component 110 also includes a connecting column 140, and the two ends of the connecting column 140 are respectively connected to the first drive component 110 and the test antenna 120. The connecting column 140 is in the form of a hollow column, and a weight-reducing hole is opened on the side wall of the connecting column 140 to reduce the load of the first drive component 110 and the overall movement inertia. A shielding cover 150 is provided on the side of the first drive component 110 facing the test antenna 120. The shielding cover 150 is provided with an avoidance groove 151 to avoid the movement of the connecting column 140. A baffle plate 141 is provided on the connecting column 140 corresponding to the avoidance groove 151 to ensure that during the movement of the connecting column 140, at least part of the baffle plate 141 always blocks the avoidance groove 151, thereby ensuring that the operation of the first drive component 110 will not have too much impact on the testing of electronic products.

[0031] In this embodiment, the antenna testing mechanism may further include a fixed antenna 500, Figure 1 As shown, a plurality of fixed antennas 500 are arranged around the fixture assembly 220 and are located above the fixture assembly 220, and are suitable for electronic products that require long-distance antenna reception performance detection.

[0032] In some embodiments, in combination Figure 1 , Figure 3 and Figure 4 As shown, the test antenna module 100 also includes a first adjustment component 130, which includes a plurality of linear adjustment modules 131 and a plurality of angle adjustment modules 132 stacked along a first direction. The linear adjustment module 131 can drive the test antenna 120 to move along a plane perpendicular to the first direction, and the angle adjustment module 132 can drive the test antenna 120 to swing relative to the electronic product.

[0033] In this embodiment, the linear adjustment module 131 and the angle adjustment module 132 stacked along the first direction ensure that the overall integration of the first adjustment component 130 in the first direction is reduced, which is beneficial to maintaining balance when the first driving component 110 drives the first adjustment component 130 to reciprocate at a high frequency; and the first adjustment component 130 can drive the test antenna 120 to move relative to the fixture component 220 (that is, relative to the electronic product), and adjust the antenna position of different electronic products to ensure the signal transmission effect and connection stability between the test antenna 120 and the antenna of the electronic product.

[0034] In this embodiment, two linear adjustment modules 131 and two angle adjustment modules 132 are arranged from top to bottom along the Z direction, and the linear movement directions of the two linear adjustment modules 131 are perpendicular to each other, ensuring translation on a plane perpendicular to the first direction; the rotation axes of the two angle adjustment modules 132 are perpendicular to each other; of course, in other embodiments, a larger number of linear adjustment modules 131 or angle adjustment modules 132 may also be arranged, and the linear movement directions of different linear adjustment modules 131 may be set at other angles, and the rotation axis angles of different angle adjustment modules 132 may also be set at other angles.

[0035] In some embodiments, in combination Figure 1 , Figure 3 and Figure 4 As shown, the linear adjustment module 131 includes a first adjustment block 1311 and a second adjustment block 1312 that can move relative to each other, a first adjustment push rod 1313 and a first connecting block 1314, the first connecting block 1314 is threadedly connected to the first adjustment push rod 1313, one of the first adjustment block 1311 and the second adjustment block 1312 is connected to the first connecting block 1314, and the other is connected to one end of the first adjustment push rod 1313.

[0036] In this embodiment, taking the connection between the first adjustment block 1311 and one end of the first adjustment top rod 1313 as an example, the first adjustment top rod 1313 is rotated to make the first adjustment top rod 1313 move linearly relative to the first connecting block 1314 and the second adjustment block 1312, and the first adjustment top rod 1313 drives the first adjustment block 1311 to move linearly relative to the second adjustment block 1312. Manual adjustment is achieved through the above structure, avoiding the introduction of electronic components in the linear adjustment module 131, thereby preventing the linear adjustment module 131 from interfering with the testing process of electronic products.

[0037] In some embodiments, in combination Figure 1 , Figure 3 and Figure 4 As shown, the angle adjustment module 132 includes a third adjustment block 1321 and a fourth adjustment block 1322 that can rotate relative to each other, and an angle knob 1323. One of the third adjustment block 1321 and the fourth adjustment block 1322 is provided with a rack portion 1324 that cooperates with the angle knob 1323 gear, and the other is rotatably connected to the angle knob 1323.

[0038] In this embodiment, taking the example that the rack portion 1324 is arranged on the third adjustment block 1321 and the angle knob 1323 is connected to the fourth adjustment block 1322, the angle knob 1323 is rotated to drive the matching rack portion 1324 to rotate, and the rack portion 1324 drives the third adjustment block 1321 to rotate relative to the fourth adjustment block 1322. Manual adjustment is achieved through the above structure, avoiding the introduction of electronic components in the linear adjustment module 131, and preventing the linear adjustment module 131 from interfering with the testing process of electronic products.

[0039] In some embodiments, in combination Figure 1 and Figure 5 As shown, the second driving assembly 210 includes a first rotating module 211, a second rotating module 212 and a connecting bracket 213. The first rotating module 211 includes a first rotating part 2111, the second rotating module 212 includes a second rotating part 2121, and the two ends of the connecting bracket 213 are respectively connected to the first rotating part 2111 and the second rotating part 2121. The rotation axis of the first rotating part 2111 is perpendicular to the first direction, the rotation axis of the second rotating part 2121 is parallel to the first direction, and the second rotating part 2121 is connected to the fixture assembly 220. The first rotating part 2111 drives the connecting bracket 213 and the second rotating part 2121 to rotate as a whole around the X axis shown in the figure, and the second rotating part 2121 drives the electronic product on the fixture assembly 220 to rotate around the Z axis shown in the figure. The electronic product can be flexibly moved within a certain range through the combined rotation of the first rotating part 2111 and the second rotating part 2121, and the position of the test antenna 120 can be effectively matched.

[0040] In this embodiment, the antenna testing mechanism further includes a calibration module 700, and the corresponding calibration module 700 can be provided with a receiving end on the rotation axis of the first rotating module 211 to receive the calibration signal emitted by the calibration module 700, so as to ensure the overall positional relationship between the rotation axis of the first rotating module and the remaining components of the antenna testing mechanism, and ensure that the positional orientation required to be adjusted between the electronic product and the test antenna 120 on the fixture assembly 220 is within the adjustment range of the first driving assembly 110 and the second driving assembly 210. In this embodiment, the calibration module 700 can be a cross laser transmitter that can emit a linear laser, and a laser receiver is provided on the rotation axis of the first rotating module 211 to receive the light emitted by the cross laser transmitter, indicating that the first rotating module 211 is installed in place.

[0041] In this embodiment, a first mounting position 2131 is provided on the connecting bracket 213, and the first mounting position 2131 is located between the first rotating part 2111 and the second rotating part 2121. The first mounting position 2131 is suitable for installing a data acquisition device, wherein the data acquisition device and the electronic product on the fixture assembly 220 are electrically connected through a data acquisition harness for collecting evaluable parameters converted by the electronic product. By setting the first mounting position 2131 on the connecting bracket 213, the data acquisition harness between the electronic product and the data acquisition device can be buried in the connecting bracket 213, thereby improving the integration of the antenna testing mechanism and reducing the occupied volume. At the same time, the absorbing cotton 400 wrapped around the outside of the connecting bracket 213 reduces the interference of the data acquisition harness on the antenna testing process.

[0042] In some embodiments, in combination Figure 1 and Figure 5 As shown, the connecting bracket 213 is further provided with a second mounting position 2132 , and the second mounting position 2132 and the first mounting position 2131 are stacked along the first direction, and the second mounting position 2132 is suitable for installing a data acquisition device.

[0043] In this embodiment, the different distances between the stacked first mounting position 2131 and the second mounting position 2132 and the fixture assembly 220 result in different lengths of the data acquisition harness. When the same data acquisition device is used in the first mounting position 2131 and the second mounting position 2132, the effect of the length of the data acquisition harness on the information transmission of the electronic product can be tested when the electronic product uses the harness to transmit information.

[0044] Furthermore, different data acquisition devices may be provided at the first installation position 2131 and the second installation position 2132 to collect different parameters for performance tests of different electronic products, or to collect different performance parameters of the same electronic product.

[0045] In one embodiment, in combination Figure 1 and Figure 5 As shown, the first rotating module 211 further includes a first rotating housing 2112, which is sleeved on the first rotating portion 2111.

The wiring harness (data transmission wiring harness, electric control wiring harness, etc.) required for the first rotating module 211 can be arranged in the first wiring space 2113, which will not interfere with the antenna testing process.

The second rotating housing 2122 is provided with a second wiring space 2123, and the second wiring space 2123 is arranged around the second rotating portion 2121. The wiring harness (data transmission wiring harness, electric control wiring harness, etc.) required for the second rotating module 212 can be arranged in the second wiring space 2123, which will not interfere with the antenna testing process.

[0047] In some embodiments, in combination Figure 1 , Figure 6 and Figure 7 As shown, the fixture assembly 220 includes a second adjustment assembly 221 and a connecting plate 222. The connecting plate 222 moves along a plane perpendicular to the first direction (Z direction in the figure) under the drive of the second adjustment assembly 221, thereby realizing position adjustment between the fixture assembly 220 and the test antenna 120 to adapt to the test of electronic products with different antenna positions.

[0048] In this embodiment, the connecting plate 222 is provided with at least two installation positions, and different installation positions are adapted to different electronic products. Figure 6 As shown, the transition plate can be connected to adapt to the installation of mobile phones and tablets; Figure 7 The PCB board can be connected through the limit column. The connecting plate 222 can be adapted to a variety of different electronic products to improve the adaptability of the antenna test mechanism. Of course, more different forms of electronic products can be adapted by setting more holes on the connecting plate 222.

[0049] In some embodiments, in combination Figure 6 As shown, the clamp assembly 220 also includes a positioning substrate 223, a positioning base column 224 and an elastic module 225. The positioning substrate 223 can be detachably connected to the connecting plate 222. A plurality of positioning holes are arranged on the positioning substrate 223. Some of the positioning holes are suitable for connecting with the positioning base column 224 and enclosing to form a positioning groove 226. The positioning groove 226 is suitable for placing electronic products. The elastic module 225 is connected to the positioning base column 224 and is suitable for pushing the electronic products in the positioning groove 226 so that the electronic products are limited and fixed in the positioning groove 226.

[0050] In this embodiment, the positioning base column 224 is connected to different positioning holes on the positioning substrate 223 to change the shape of the positioning groove 226 to adapt to electronic products with similar but different structural shapes (such as mobile phones of different brands).

[0051] In this embodiment, the positioning substrate 223 and the connecting plate 222 are detachably connected via a transition plate 227, and by replacing different positioning substrates 223, the positioning hole layout can be changed to form more diverse positioning grooves 226 to adapt to different types of electronic products, such as replacing a larger positioning substrate 223 to adapt to tablets of different brands.

[0053] On the other hand, the present invention further provides a shielding box, comprising the antenna testing mechanism of the above embodiment, and its technical effect is the same as that of the antenna testing mechanism of the first embodiment of the present application, and will not be described in detail here.

[0054] In some embodiments, in combination Figure 8 and Fig. 9 As shown, the shielding box also includes a shielding shell 300, and the shielding shell 300 is surrounded by a shielding space 310, and an antenna test mechanism is installed in the shielding space 310. The shielding shell 300 provides a relatively closed and controllable test environment, which can simulate ideal space conditions, so that the antenna test mechanism can be carried out in an environment without interference or with low interference, thereby improving the accuracy and stability of the antenna test results.

[0055] In this embodiment, combined with Figure 1 , Figure 8 and Fig. 9 As shown, a lighting lamp 600 is also provided in the shielding box to provide light for the convenience of operation of the staff.

[0056] In one embodiment, in combination Figure 8 and Fig. 9 As shown, the shielding box also includes a temperature control component. The shielding shell 300 is provided with an air inlet 320 and an air outlet 330. The air inlet 320, the shielding space 310, the air outlet 330 and the temperature control component are connected in sequence to form a circulating air circuit.

[0057] In this embodiment, the temperature of the gas introduced into the temperature control component is changed to simulate the operation process of the electronic product under different operating temperatures, and the operation effect of the antenna of the electronic product is detected.

[0058] In this embodiment, the temperature adjustment range of the temperature control component is between -40 degrees Celsius and 100 degrees Celsius.

[0059] In this embodiment, the temperature control component can adopt a hot / cold shock machine, a compression air conditioner, etc. Of course, based on different types of temperature control components, the corresponding temperature adjustment range that can be achieved needs to be adaptively adjusted.

The filter connector 340 only allows signals of a specific frequency band to pass through its internal filtering network (such as a passive filtering network composed of components such as inductors and capacitors), and filters out interference signals of other frequency bands, thereby ensuring the normal operation of the wiring harness inside the shielding box.
