Description

Technical Field

[0001] The invention relates to the field of radar testing, in particular to a radar testing box. Background Art

[0002] Radar is an electronic device that uses electromagnetic waves to detect targets. It emits electromagnetic waves (for example, millimeter waves) to illuminate the target and receive its echo, thereby obtaining information such as the distance from the target to the transmitting point, the rate of change of distance, azimuth, and altitude. During the production process of radar, the radar needs to be tested to test its reliability.

[0003] Existing radar test boxes need to test the temperature resistance of the radar, and a heat dissipation structure composed of heat sinks will be added inside the test box to prevent the test box from being damaged by excessively high temperature for a long time. However, due to the poor heat dissipation effect of the heat sink, it is difficult to quickly dissipate the heat inside the test box by adding heat sinks and other heat dissipation structures, which prolongs the time that the excessively high temperature inside the test box is maintained, which may accelerate the damage of the radar, thereby affecting the test effect of the radar test box on the radar.

A driven gear 909 is sleeved on one side of the outer wall of the rotating shaft 907. A plurality of rotating blades 906 are arranged on the outer wall of the rotating shaft 907.

[0039] Specifically, the flip assembly 8 includes a driving motor 801 installed on one side of the box body 1, two movable shafts 807 arranged on one side of the box body 1 through bearings, and a driven shaft 805 arranged on the other side of the box body 1 through bearings. The outer wall of the driven shaft 805 is sleeved with a driven sprocket 806. The output end of the driving motor 801 is connected to a driving shaft 802 extending to the inside of the box body 1. The outer wall of the driving shaft 802 is sleeved with a driving sprocket 803, and a chain 804 is sleeved between the driving sprocket 803 and the driven sprocket 806. The driving gear 908 is meshed with the driven gear 909. The diameter of the driving gear 908 is larger than the diameter of the driven gear 909. When the driving gear 908 rotates, it will drive the driven gear 909 to rotate. After the driven gear 909 rotates, it will drive the rotating shaft 907 to rotate. There is a movable shaft 807 and the driven shaft 805 and another movable shaft 804. A placement plate 10 is connected between the shaft 807 and the drive shaft 802. When the radar needs to be flipped, the user can start the drive motor 801. The drive motor 801 can drive the drive shaft 802 to rotate, and then drive the active sprocket 803 to rotate. A sealed door 13 is installed on the outer surface of the box 1. The user can open the sealed door 13 to take and place the radar on the placement plate 10, and a control panel 14 and an observation window 15 are respectively installed on the outer surface of the sealed door 13. The control panel 14 is electrically connected to the electric heating plate 2, the temperature sensor 12, the electromagnet block 902, the electromagnet bar 11 and the drive motor 801, so that the user can start or turn off the electric heating plate 2, the temperature sensor 12, the electromagnet block 902, the electromagnet bar 11 and the drive motor 801 through the control panel 14. At the same time, the user can observe the situation inside the box 1 through the observation window 15.

[0040] The implementation principle of this embodiment is as follows: first, the user can install the test box and turn on the power supply, then open the sealing door 13, and place the radar at the top middle position of the placement plate 10, so that the bottom of the installation plate 16 contacts the placement plate 10, and then rotate the threaded column 709. After the threaded column 709 rotates, it will drive the gear 708 to rotate. When the gear 708 rotates, it will drive the two racks 703 to move towards each other. After the rack 703 moves, it will drive the limit block 702 to slide inside the limit groove 701, and then drive the card plate 704 to move, so that the card plate 704 is stuck in the card groove 705, so as to limit the installation plate 16 and the radar;

[0041] Then, the temperature sensor 12 and the electric heating plate 2 are started. The electric heating plate 2 can heat the air to increase the temperature inside the box 1 so as to test the temperature resistance of the radar. During the test, the driving motor 801 can be started. The driving motor 801 can drive the driving shaft 802 to rotate, and then drive the driving sprocket 803 to rotate, and then drive the chain 804 to rotate, thereby driving the driven sprocket 806 to rotate, and drive the placement plate 10 to rotate, so that the placement plate 10 drives the radar to flip, so that the radar is heated evenly.

[0042] When the temperature sensor 12 can detect that the temperature inside the box 1 is too high, it will transmit a signal to the control panel 14. After receiving the signal, the control panel 14 will start the electromagnet bar 11 and the electromagnet block 902. The electromagnet bar 11 will generate magnetism when it is energized, and then it can absorb the permanent magnet bar 5, so that the blocking plate 6 moves up and no longer blocks the air inlet 3. At the same time, when the electromagnet block 902 is energized, it will generate magnetism and then it can absorb the permanent magnet block 904, so that the permanent magnet block 904 moves up. After the permanent magnet block 904 moves up, it no longer blocks the exhaust hole 903. When the movable shaft 807 rotates, it will drive the active gear 908 to rotate. When the active gear 908 rotates, it will drive the driven gear 909 to rotate. After the driven gear 909 rotates, it will drive the rotating shaft 907 to rotate, and then drive the rotating blade 906 to rotate, thereby accelerating the air circulation speed inside the box 1, so that the hot air can quickly enter the active cavity 901 and be discharged through the exhaust hole 903, so as to quickly cool down the box 1.
