[0002] As an indispensable part of modern life, the safety and efficiency of wireless chargers are of paramount importance to users. Therefore, rigorous testing is essential to ensure the quality and performance of wireless chargers.

[0003] Wireless charging products are intentional radiators. Their working principle is to transmit energy through electromagnetic fields. Therefore, they must pass FCC certification to ensure that their electromagnetic radiation will not interfere with other devices and that it meets the safety limits for human exposure to electromagnetic fields. Therefore, electromagnetic radiation intensity testing and electromagnetic radiation uniformity testing are required. However, these tests are usually conducted using separate testing devices, which makes the testing process too cumbersome. Utility Model Content

An angle adjustment assembly is provided inside the box 11. A lifting frame b12 is rotatably connected to the lower surface of the power box 11. A second lifting assembly is provided inside the lifting frame b12. The front of the lifting frame b12 is slidably connected to the back of the extension frame 14. An extension assembly is provided inside the extension frame 14. The left and right sides of the inner wall of the extension frame 14 are slidably connected to the left and right sides of the mounting block 153, respectively. A detection probe 16 is installed on the lower surface of the mounting block 153. An electromagnetic radiation detector body 8 is installed on the upper surface of the test platform 1.

[0032] Specifically, the first lifting assembly includes a screw a42 that is rotatably connected to the lower surface of the inner wall of the lifting frame a3. The top end of the screw a42 passes through the upper surface of the inner wall of the lifting frame a3 and is fixedly connected to the lower surface of the handwheel 41. The outer surface of the screw a42 is threadedly connected to a threaded sleeve a43, and the right side of the threaded sleeve a43 is fixedly connected to an isolation box 9.

[0033] Rotating the handwheel 41 drives the screw a42 to rotate. The rotation of the screw a42 causes the threaded sleeve a43 and the isolation box 9 to move downward. The isolation box 9 moves downward and fits against the upper surface of the isolation base 2, thus isolating the electromagnetic radiation generated during the wireless charging product test.

[0034] Specifically, the fixing component includes a slide rod 71 that is fixedly connected to the front and back of the inner wall of the moving groove 6. A sliding sleeve 73 is slidably connected to the outer surface of the slide rod 71. A clamping plate 74 is fixedly connected to the upper surface of the sliding sleeve 73. The back of the sliding sleeve 73 is fixedly connected to the front of the spring 72. The back of the spring 72 is fixedly connected to the back of the inner wall of the moving groove 6.

[0035] Place the wireless charging product on the upper surface of the isolation base 2, insert the wireless charging product into the connecting block 5, and make an electrical connection to the wireless charging product. Pull the clamp 74 to move backward, and the clamp 74 and the sliding sleeve 73 move backward to compress the spring 72. The spring 72 pushes the clamp 74 to clamp and fix the wireless charging product.

[0036] Specifically, the angle adjustment assembly includes a servo motor a101 mounted on the lower surface of the inner wall of the power box 11. The output shaft of the servo motor a101 is fixedly connected to the upper surface of the gear a102. The outer surface of the gear a102 meshes with the outer surface of the gear b103. The lower surface of the gear b103 is fixedly connected to the upper surface of the lifting frame b12 through a bearing and a rotating shaft mounted on the lower surface of the inner wall of the power box 11.

[0037] Servo motor a101 drives gears a102 and b103 to rotate. The rotation of gear b103 drives the lifting frame b12, extension frame 14 and detection probe 16 to adjust their angles so as to detect the electromagnetic radiation generated around the wireless charging product.

[0038] Specifically, the second lifting assembly includes a servo motor b131 installed on the lower surface of the inner wall of the lifting frame b12. The output shaft of the servo motor b131 is fixedly connected to the bottom end of the screw b132, the top end of the screw b132 is rotatably connected to the upper surface of the inner wall of the lifting frame b12, and a threaded sleeve b133 is threadedly connected to the outer surface of the screw b132. An extension frame 14 is fixedly connected to the front side of the threaded sleeve b133.

[0039] Servo motor b131 drives screw b132 to rotate. The rotation of screw b132 causes threaded sleeve b133 and extension frame 14 to move downward. The downward movement of extension frame 14 causes detection probe 16 to move downward, thereby detecting the electromagnetic radiation generated by wireless charging products.

[0040] Specifically, the extension assembly includes a servo motor c151 mounted on the front side of the inner wall of the extension frame 14. The output shaft of the servo motor c151 is fixedly connected to one end of the front side of the screw c152, and one end of the back side of the screw c152 passes through a screw hole opened on the front side of the mounting block 153 and is rotatably connected to the back side of the inner wall of the extension frame 14.

[0041] Servo motor C151 drives screw C152 to rotate. The rotation of screw C152 causes mounting block 153 and detection probe 16 to move forward, adjusting the electromagnetic radiation detection range of wireless charging products.

[0042] Working principle and usage process of this utility model:

[0043] In use, this utility model is as follows:

[0044] The wireless charging product is placed on the upper surface of the isolation base 2, and the wireless charging product is inserted into the connecting block 5 to establish an electrical connection. Pulling the clamping plate 74 backward causes the clamping plate 74 and sliding sleeve 73 to move backward, compressing the spring 72. The spring 72 pushes the clamping plate 74 to clamp and fix the wireless charging product. Rotating the handwheel 41 drives the screw a42 to rotate. The rotation of the screw a42 causes the threaded sleeve a43 and the isolation box 9 to move downward, bringing the isolation box 9 into contact with the upper surface of the isolation base 2, thus isolating the electromagnetic radiation generated during the wireless charging product test. The servo motor b131 drives the screw b132 to rotate. The threaded sleeve b133 and the extension frame 14 move downwards, which in turn moves the detection probe 16 downwards to detect the electromagnetic radiation generated by the wireless charging product. The servo motor c151 drives the screw c152 to rotate, which in turn moves the mounting block 153 and the detection probe 16 forward to adjust the electromagnetic radiation detection range of the wireless charging product. The servo motor a101 drives the gears a102 and b103 to rotate, which in turn moves the lifting frame b12, the extension frame 14, and the detection probe 16 to adjust their angles to facilitate the detection of electromagnetic radiation generated around the wireless charging product.
