[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] like Figures 1 to 4 As shown, an embodiment of the present invention provides an antenna testing device, including a box 1, a feed assembly 7, a reflector 8, a mounting base 31, a shielding door 2 and a position detection mechanism. A test cavity 3 is provided in the box 1, and the feed assembly 7, the reflector 8 and the mounting base 31 are all installed in the test cavity 3. The mounting base 31 is used to install the antenna to be tested, and the reflector 8 is used to reflect the electromagnetic waves emitted by the feed assembly 7 into the test cavity 3.

[0028] The box body 1 is provided with an opening 32 for the antenna to be tested to enter and exit the test cavity 3. The shielding door 2 is movably connected to the box body 1. The shielding door 2 has a blocking position for blocking the opening 32 and an open position for fully opening the opening 32. The position detection mechanism is used to detect the position of the shielding door 2. The position detection mechanism is communicatively connected with the feed assembly 7. The feed assembly 7 can be closed when the shielding door 2 leaves the blocking position.

[0029] Specifically, the position detection mechanism detects the position of the shielding door 2 in real time, and the position detection mechanism feeds back the detected position information to the feed component 7. When the shielding door 2 leaves the blocking position, the feed component 7 automatically closes and stops emitting electromagnetic waves to the reflector 8, so that after the shielding door 2 is opened, no electromagnetic waves are generated in the test chamber 3, and the operator can safely enter and exit the test chamber 3.

[0030] In one embodiment, a first driving mechanism 4 is further included, and the first driving mechanism 4 is used to drive the screen door 2 to move between the blocking position and the open position.

[0031] Specifically, the first driving mechanism 4 autonomously drives the shielding door 2 to move between the blocking position and the open position. The first driving mechanism 4 drives the shielding door 2 to automatically move between the blocking position and the open position, which can save manpower and improve the test phase rate.

[0032] In one embodiment, the shielding door 2 is rotatably connected to the box body 1, and the first driving mechanism 4 is connected between the box body 1 and the shielding door 2. The first driving mechanism 4 is used to drive the shielding door 2 to swing between a first angle and a second angle. At the first angle, the shielding door 2 is in the blocking position, and at the second angle, the shielding door 2 is in the open position.

[0033] Specifically, in this embodiment, the first drive mechanism 4 is a pneumatic cylinder 5. The cylinder body of the pneumatic cylinder 5 is hingedly connected to the inner wall of the test chamber 3, and the piston rod of the pneumatic cylinder 5 is hingedly connected to the shielding door 2. When the piston rod of the pneumatic cylinder 5 extends out of the cylinder body, it drives the shielding door 2 to swing toward a first angle, thereby moving the shielding door 2 to a blocking position, thereby blocking the opening 32. When the piston rod of the pneumatic cylinder 5 retracts into the cylinder body, it drives the shielding door 2 to swing toward a second angle, thereby moving the shielding door 2 to an open position, thereby opening the opening 32. The first drive mechanism 4 drives the shielding door 2 to swing, facilitating installation, and does not occupy the internal space of the test chamber 3, thereby not affecting the formation of the static field within the test chamber 3.

[0034] In one embodiment, the position detection mechanism includes an angle sensor 6 connected to the box body 1 , and the angle sensor 6 is used to detect the angle of the shielding door 2 .

[0035] Specifically, the position detection mechanism includes an angle sensor 6, which is installed on the shielding door 2.

[0037] Specifically, the transport component 9 is installed in the test chamber 3, and the mounting seat 31 is connected to the transport component 9. The transport component 9 is used to drive the mounting seat 31 in and out of the test chamber 3. The operator does not need to enter the test chamber 3, thereby avoiding the residual electromagnetic waves in the test chamber 3 from endangering the operator, further improving the safety of the antenna testing equipment.

[0038] In one embodiment, the transport assembly 9 includes a translation unit, which includes a first slide rail 13, a first slider 14, a mounting plate 16 and a second driving mechanism 10. The first slide rail 13 is arranged on the bottom wall of the test cavity 3, and the mounting plate 16 is connected to the first slider 14.

The first slider 14 is connected to the second driving mechanism 10, and the second driving mechanism 10 is connected to the bottom wall of the cavity. The second driving mechanism 10 is used to drive the first slider 14 to move toward or away from the opening 32, and the mounting seat 31 is connected to the mounting plate 16.

[0039] Specifically, the second drive mechanism 10 includes a translation screw 12 and a translation motor 11. A first slide rail 13 is mounted on the bottom wall of the test chamber 3.

The first slider 14 is also screw-assembled with the translation screw 12. A mounting plate 16 is mounted on the upper side of the first slider 14, and a mounting seat 31 is connected to the mounting plate 16. The translation motor 11 drives the translation screw 12 to rotate. When the translation screw 12 rotates, the first slider 14 drives the mounting plate 16 and the mounting seat 31 to move toward or away from the opening 32, thereby allowing the mounting seat 31 to enter and exit the test chamber 3 through the opening 32. The translation movement of the first slider 14 is driven by the screw-nut mechanism, which has a simple structure and is easy to design and install.

[0040] In one embodiment, the transport component 9 also includes a first rotating unit, which includes a first rotatable seat 19, an extension arm 33 and a third driving mechanism 17.

[0042] Specifically, the third drive mechanism 17 is a first rotary motor 18, which is transmission-connected to a first rotatable base 19. In this embodiment, the transmission connection between the first rotary motor 18 and the first rotatable base 19 can be a belt drive or a rack and pinion drive. The first rotatable base 19 is rotatably mounted on the mounting plate 16 and driven by the first rotary motor 18 to rotate about a first rotation axis between a third and a fourth angle. The first rotation axis is vertically disposed and perpendicular to the first slide rail 13, enabling the first rotatable base 19 to rotate horizontally on the mounting plate 16. When the first rotatable base 19 is at the third angle, the extension arm 33 is perpendicular to the first slide rail 13, allowing the mounting base 31 to be moved deeper into the test cavity 3. When the first rotatable base 19 is at the fourth angle, the extension arm 33 is parallel to the first slide rail 13, facilitating the removal of the mounting base 31 from the test cavity 3. The mounting base 31 is connected to the second rotatable base 23 via the extension arm 33, allowing the mounting base 31 to be moved deeper into the test cavity 3, thereby improving testing performance.

In this embodiment, the "transmission connection" between the second rotating motor 22 and the second rotatable seat 23 can be a belt drive structure or a gear rack drive structure. The second rotatable seat 23 is rotatably assembled on the first rotatable seat 19, and the second rotating motor 22 drives the second rotatable seat 23 to rotate around the second rotation axis. The second rotation axis is horizontally arranged, and the second rotation axis intersects the first rotation axis vertically, so that the second rotatable seat 23 can rotate vertically on the mounting plate 16, thereby driving the mounting seat 31 to rotate vertically through the extension arm 33, so that the direction of the antenna to be tested can be adjusted, thereby improving the test effect of the antenna's transmitting and receiving performance.

[0045] In one embodiment, the transport component 9 also includes a lifting unit, which includes a lifting plate 26 and a fifth driving mechanism 24. The end of the extension arm 33 away from the mounting seat 31 is connected to the lifting plate 26, and the fifth driving mechanism 24 is connected to the second rotating seat 23. The lifting plate 26 is slidingly connected to the second rotating seat 23, and the lifting plate 26 is connected to the fifth driving mechanism 24.

[0046] Specifically, the fifth driving mechanism 24 includes a lifting screw, a lifting motor 7 and a second slide rail 25. The lifting motor 7 is installed on the first rotating seat 19, and the second slide rail 25 is installed on the second rotating seat 23 extending in the up and down directions.

The top end of the lifting screw is rotatably assembled with the second rotating seat 23, and the bottom end of the lifting screw is transmission-connected to the lifting motor 7. In this embodiment, the "transmission connection" between the lifting motor 7 and the lifting screw can be a belt transmission structure or a gear rack transmission structure.

[0047] The second slide rail 25 is connected to the second rotating seat 23, and the lifting plate 26 is provided with a second slide groove 27 on the side facing the second rotating seat 23. The second slide groove 27 is slidably connected to the second slide rail 25. The lifting plate 26 is also spirally assembled with the lifting screw. The lifting motor 7 drives the lifting screw to rotate. When the lifting screw rotates, the lifting plate 26 drives the extension arm 33 and the mounting seat 31 to move up and down, which can increase the installation space of the antenna and improve the applicability of the antenna testing equipment.

[0048] In one embodiment, the transport component 9 also includes a third rotating unit, which includes a third swivel seat 30 and a sixth driving mechanism 28.

The third rotation axis is vertically arranged and parallel to the first rotation axis, so that the second rotating base 23 can rotate horizontally on the extension arm 33. In addition, the third rotation axis intersects the second rotation axis vertically, so that the antenna to be tested can rotate around the intersection of the third rotation axis and the second rotation axis, thereby increasing the rotation range of the antenna and further improving the test effect of the antenna's transmitting and receiving performance.

[0050] In this embodiment, the transport assembly 9 further includes a housing 201 , in which the second rotating motor 22 is installed. The housing 201 is used to protect the second rotating motor 22 and the first rotating seat 19 .

[0051] The antenna testing device of the present invention works as follows:

[0052] When the antenna needs to be tested, the first driving mechanism 4 drives the shielding door 2 to open and the feed assembly 7 to close. The third driving mechanism 17 first drives the first rotating seat 19 to rotate so that the extension arm 33 is parallel to the first slide rail 13. Then the second driving mechanism 10 drives the mounting plate 16 to drive the extension arm 33 and the mounting seat 31 to move toward the opening 32, so that the mounting seat 31 extends out of the test cavity 3. The operator installs the antenna to be tested on the mounting seat 31. Then the second driving mechanism 10 drives the mounting plate 16 to drive the extension arm 33 and the mounting seat 31 into the test cavity 3. The third driving mechanism 1 7 drives the first rotating seat 19 to rotate again, so that the extension arm 33 is perpendicular to the first slide rail 13, so that the antenna is located in the middle of the test cavity 3. Then the shielding door 2 is closed, the feed assembly 7 is opened, and the feed assembly 7 transmits electromagnetic waves to the reflector 8, and the reflector 8 reflects the electromagnetic waves into the test cavity 3 to form a static field in the test cavity 3. During the test, the sixth driving mechanism 28 drives the mounting seat 31 to rotate horizontally, and the fourth driving mechanism 21 drives the second rotating seat 23 to drive the extension arm 33 and the mounting seat 31 to rotate vertically, thereby performing a full-scale signal receiving and transmitting performance test on the antenna.

[0053] According to the antenna testing equipment of the embodiment of the present invention, the position of the shielding door 2 can be detected in real time through the position detection mechanism. The position detection mechanism feeds back the detected position information to the feed assembly 7. When the shielding door 2 leaves the blocking position, the feed assembly 7 automatically closes and stops emitting electromagnetic waves to the reflector 8, so that after the shielding door 2 is opened, no electromagnetic waves are generated in the test cavity 3. The operator can safely enter and exit the test cavity 3. Compared with the prior art, the safety of the antenna testing equipment is improved.
