[0025] In order to make the utility model purpose, features, and advantages of the present utility model more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the following described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present utility model.

[0026] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0027] Please refer to Figures 1 - 5 As shown, the present utility model designs an antenna testing device, which includes a testing machine 1. The testing machine 1 is provided with a testing board 16, a limiting port, a vacuum assembly, and a pressing assembly. The testing board 16 is connected with a limiting board 2 through a first elastic member 15. The limiting board 2 passes through the limiting port and is provided with a limiting groove 3, a first through hole 4, and a second through hole 5. The size of the limiting groove 3 matches the size of the antenna. The first through hole 4 communicates with the limiting groove and is connected to the vacuum assembly. The second through hole 5 corresponds to the test point of the antenna. The pressing assembly is used to press the limiting board 2 and the antenna limited in the limiting groove 3 so that the antenna is electrically connected to the testing board 16.

[0028] Specifically, a plurality of probes are provided on the testing board 16, and the probes correspond to the test points of the antenna one by one.

[0029] It should be noted that before the test, the staff only needs to place the antenna in the limiting groove 3 so that the antenna fits with the limiting groove 3, and then start the vacuum assembly. The negative pressure generated by the vacuum assembly can fix the antenna to avoid the antenna bending. Finally, start the pressing assembly. When the pressing assembly presses the limiting groove 3 and the antenna, and the antenna passes through the second through hole 5 and is electrically connected to the testing board 16, the testing board 16 can detect the test points of the antenna. A plurality of probes are provided on the testing board 16, and the probes correspond to the test points of the antenna one by one. During one test cycle, the performance evaluation of all test points on the antenna can be completed without replacing the probes one by one or adjusting the antenna position. This parallel processing ability greatly shortens the test cycle and improves the test efficiency.

[0030] Specifically, the antenna testing device further includes a first guiding post 6. The first guiding post 6 is connected to the test board 16 and penetrates through the limiting plate 2. Due to the penetrating effect of the first guiding post 6, the limiting plate 2 can always maintain a facing relationship with the test board 16 during the movement process. This facing property ensures that the limiting plate 2 can move or adjust its position along a predetermined trajectory, avoiding deviation or inclination, which helps to achieve a one-to-one correspondence between the probe and the antenna test point, and also ensures the stable transmission and reception of signals during the test process. If there is an angular deviation between the limiting plate 2 and the test board 16, it may lead to inaccurate or invalid test results.

[0031] Specifically, the pressing assembly includes a driver, a first pressing block 7 and a second pressing block 8. The driver is connected to the first pressing block 7, and the second pressing block 8 is connected to the lower part of the first pressing block 7. When the driver drives the first pressing block 7 to descend to a first height, the second pressing block 8 presses the antenna. When it continues to descend to a second height, the first pressing block 7 presses the limiting plate 2.

[0032] It should be noted that when the driver drives the first pressing block 7 to descend to the first height, the second pressing block 8 will abut against the antenna, eliminating the slight bending or gap generated by the flexibility of the antenna, and making the test point of the antenna pass through the second through hole 5. As the driver continues to drive, the first pressing block 7 will press the limiting plate 2, causing the first elastic member 15 to compress. When the third pressing block 9 is driven to descend to a third height, the test point of the antenna will be electrically connected to the probe on the test board 16, and the test board 16 can then test the antenna. Of course, it should be noted that the present utility model does not limit the first height, the second height and the third height.

[0033] Specifically, the antenna testing device further includes a second elastic member 12 and a third pressing block 9. The two ends of the second elastic member 12 are respectively connected to the second pressing block 8 and the first pressing block 7. The third pressing block 9 is connected to the first pressing block 7 and the second guiding post 10. The testing machine 1 is provided with a guiding hole 11 corresponding to the position of the second guiding post 10.

[0034] The second elastic member 12 (such as a spring or an elastic gasket, etc.) is connected between the second pressing block 8 and the first pressing block 7, playing a role of buffering and shock absorption. When the antenna is pressed, the second elastic member 12 can absorb part of the impact force and vibration, preventing the antenna from being damaged due to excessive pressure. At the same time, it can also help to maintain the uniform distribution of the pressing force and improve the accuracy of the test. The second guiding post 10 cooperates with the guiding hole 11 on the testing machine 1, providing an accurate guiding path for the movement of the second pressing block 8 and the first pressing block 7, further improving the positioning accuracy and reliability of the pressing assembly.

[0035] Specifically, the antenna testing device further includes a connecting block 13 , which is detachably connected to the testing machine 1 , and a driver is a slide cylinder 14 , a fixed end of the slide cylinder 14 is connected to the connecting block 13 , and a telescopic end of the slide cylinder 14 is connected to the third pressing block 9 .

[0036] The connecting block 13 serves as a bridge between the test machine 1 and the driver, realizing a detachable connection between the two, which not only facilitates the assembly and maintenance of the test device, but also improves the flexibility and scalability of the equipment. When the driver needs to be replaced or upgraded, it is only necessary to simply remove the connecting block 13 and reinstall the new driver. The fixed end of the slide cylinder 14 is connected to the connecting block 13, and the telescopic end is connected to the third pressure block 9. The telescopic movement of the telescopic end is used to control the lifting and lowering of the pressing assembly. Of course, in actual applications, other devices can also be used to replace the slide cylinder 14 of the utility model, and the utility model does not limit this.

[0037] Specifically, the antenna testing device further includes a power module, and the power module is electrically connected to the testing board 16 .

[0038] Specifically, the antenna testing device further includes a processing unit and a display mechanism. The processing unit is electrically connected to the display mechanism and the testing board 16. The display mechanism is used to display the test results and test data of the antenna.

[0039] The processing unit is responsible for receiving the test data from the test board 16, and processing and analyzing it to obtain the performance indicators and test results of the antenna. The display mechanism is electrically connected to the processing unit, and the display mechanism displays the processed results to the staff, which makes the test process more intuitive and convenient, and the staff can check the test progress and results at any time.

[0040] Specifically, the vacuum assembly includes an air pump and an air pipe 17, and two ends of the air pipe 17 are respectively connected to the first through hole 4 and the air pump.

[0041] It should be noted that when the staff places the antenna in the limit slot 3 and makes the antenna fit with the limit slot 3, the staff starts to pump air in the air pump. The negative pressure generated by the air pump can fix the antenna. After the test is completed, the air pump is deflated. The positive pressure generated by the air pump can make the antenna detach from the limit slot 3. The staff can remove the antenna after the test is completed, which is very convenient.

[0042] Specifically, the antenna testing device also includes a protective cover 18 and a grating assembly. The protective cover 18 is detachably connected to the testing machine 1 and is provided with a plurality of first heat dissipation holes 19. The grating assembly is arranged on the protective cover 18. The grating assembly includes a transmitter 20 and a receiver 21. The transmitter 20 is used to emit a light beam, and the receiver 21 is used to receive a light beam and is electrically connected to the testing machine 1.

[0043] The protective cover 18 provides a layer of physical protection for the testing machine 1. It is provided with a number of first heat dissipation holes 19, which help the heat dissipation of the testing machine 1 and prevent overheating. At the same time, the detachable design facilitates the maintenance and cleaning of the testing machine 1. The grating assembly forms a light curtain through the cooperation of the emitter 20 and the receiver 21. When a person or an object enters the testing area, the transmission of the light beam will be blocked. At this time, the receiver 21 will send a signal to the testing machine 1, and the safety mechanism of the testing machine 1 will be activated to cut off the operation of the testing machine 1, which effectively prevents accidents and ensures the safety of the operators. Of course, an audible and visual alarm can also be set on the testing machine 1. When the transmission of the light beam is blocked, the receiver 21 will send a signal to the audible and visual alarm, and the audible and visual alarm will be activated. When the staff sees the audible and visual alarm activated, they will immediately turn off the test of the testing machine 1.

[0044] Specifically, the antenna testing device further includes support feet 23 and a fan 22. The testing machine 1 is provided with second heat dissipation holes 24 communicating with the outside. The support feet 23 are connected to the testing machine 1 and are provided with anti-slip patterns. The fan 22 is arranged inside the testing machine 1.

[0045] During the testing process, the test board 16 will generate heat. The fan 22 accelerates the flow of hot air inside the testing machine 1 by blowing air and discharges the hot air to the outside through the second heat dissipation holes 24, thereby effectively reducing the temperature of the test board 16 assembly and other electronic components and preventing overheating damage. The anti-slip patterns can effectively increase the friction force and prevent the testing machine 1 from sliding during the testing process.

[0046] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0047] The above is the case. The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
