Specifically, the temperature, voltage and some functions of the motor controllers are simulated and tested after the motor controllers are connected to various external test equipment. The aging room equipment, also known as the burn-in room, is a device that simulates a high temperature and harsh environment test for high-performance electronic products. It is an important experimental equipment to improve product stability and reliability, and an important production process for various manufacturers to improve product quality and competitiveness. The equipment is widely used in power electronics, computers, communications, biopharmaceuticals and other fields.

[0014] The beneficial effects of the present invention are as follows:

The filling temperature measuring rod can be inserted into the adapter tube through the side clustering slide to control the flow of the gas diverted by the segmented gas cylinder, thereby achieving the effect of separate temperature control and wind force control for the motor in each layer, avoiding the problem of heat-sensitive motors being overloaded due to heat when the motors inside the test box are heated uniformly.

[0016] 2. Since the hot gas circulates inside the device and the gas discharged from each layer will flow back to the inside of the layered side shell, the layered side shell is improved. The inside of the layered side shell can be separated by a closed one-way rotating plate to achieve the function of closed insulation. The actual ambient temperature of the area where the electrical station is located can be measured according to each temperature measuring tube, thereby distinguishing the actual ambient temperature, and then timely blocking the high-temperature area from air intake by filling the temperature measuring rod to avoid overheating problems.

[0017] 3. Depending on the test motor, the inside of the electrical station can be connected to the appropriate motor by switching between the large shell and the small shell, thereby ensuring effective power supply to the motor and making the device more versatile. Since the rotating shaft can be controlled by the torsion motor to perform autonomous deflection, when the test motor is overloaded, the motor can be physically powered off by emergency torsion of the rotating shaft, thereby preventing the motor from catching fire.

[0018] 4. The switching device can drain the gas refluxed inside the device by deflecting and plugging the hollow plate, so that the refluxed gas can be directly discharged to the outside, and the heat inside the device can be dissipated to avoid heat accumulation inside the detection box. It can also connect the detection box with the outside world. Under the extraction action of the ventilation pump, the switching device can realize air intake, thereby increasing the gas flow rate filled by the ventilation pump. When the heating resistor plate stops working, the internal motor can be uniformly and quickly cooled, thereby solving the problem of motor overload and preventing the operator who removes the motor from being burned by heat.

The traction rod 23 can actively pull the clustering slide 22 to slide left and right in the horizontal direction under the control of an external operator;

[0032] The drainage device 5 includes a bent connecting plate 51, and a pressure relief port 52 is symmetrically provided at the bottom of the inner cavity of the bent connecting plate 51. When the pressure at the bottom of the device is too high, the pressure relief port 52 will open under the action of high pressure to relieve pressure. Filter mesh ports 53 are evenly provided at the top of the inner cavity of the bent connecting plate 51, and segmented air cylinders 54 are evenly provided on the top of the bent connecting plate 51. The left side of the inner cavity of the segmented air cylinder 54 is fixedly connected with an adapter tube 55 through a through-hole, and connecting air pipes 56 are symmetrically provided on the front and back sides of the inner cavity of the segmented air cylinder 54. There are three groups of segmented air cylinders 54 with the same overall structure, but the adapter tube 55 connected on the left side has a larger caliber from top to bottom to ensure that the gas flow rate entering the three-layer area of ​​the detection box 11 will not differ too much.

[0033] The reflux box 15 includes a layered side shell 151, and the inner wall of the layered side shell 151 is evenly provided with one-way rotating plates 152. The one-way rotating plates 152 can only be deflected downward or engage with each other to close each layer area of ​​the layered side shell 151. The front and back sides of the inner cavity of the reflux box 15 are evenly provided with temperature measuring tubes 153. The temperature measuring tubes 153 can detect the temperature of the gas passing into the interior. The right side of the outer surface of the reflux box 15 is fixedly connected to the left side of the outer surface of the detection box 11, and the top of the arc-shaped through plate 14 is fixedly connected to the bottom of the inner cavity of the reflux box 15 through a notch.

[0034] The front and rear sides of the heating resistor plate 12 are fixedly connected to the external heating plate 17 through the connecting wire 332, and the outer surface of the external heating plate 17 is fixedly connected to the outer surface of the detection box 11, and the right side of the inner cavity of the ventilation pump 13 is fixedly connected to the bottom of the inner wall of the bending connecting plate 51 through the direct connection plug plate. There are three cluster slide plates 22, three segmented air cylinders 54, and the bottom of the inner cavity of the lowest segmented air cylinder 54 is fixedly connected to the top of the outer surface of the bending connecting plate 51. The left end of the adapter tube 55 extends to the inside of the detection box 11 through the through-hole, and the outer surface of the filling temperature measuring rod 24 is slidably connected to the inner cavity of the segmented air cylinder 54 through the plug interface, and the left end of the filling temperature measuring rod 24 is plugged into the inner wall of the adapter tube 55.

[0035] Before using the device for testing, open the rotating door panel 16 in front, select the electrical platform 3 at a suitable position according to the model of the motor, connect the terminal of the motor to the inside of the electrical platform 3, fill all the electrical platforms 3 in turn, close the rotating door panel 16, and start the testing work.

[0036] The electrical station 3 supplies power to each motor to simulate the working state of the motor. The ventilation pump 13 located below will draw external air into the interior of the detection box 11 through the switching device 4. Then, when the gas passes through the middle heating resistor plate 12 from left to right, it will be heated by the high-temperature heating resistor plate 12, and then filled into the interior of the bent connecting plate 51 under the action of pressure. Dust and other impurities are removed through the filtering work of the filter mesh port 53. The airflow passes through three segmented air cylinders 54 from top to bottom in turn, and is filled into the area where each layer of the electrical station 3 is located through the adapter tube 55 of each segmented air cylinder 54. The airflow flows from right to left in the area where the electrical station 3 is located, heats the internal motor, and then enters the interior of the layered side shell 151, and then flows back to the switching device 4 through the layered side shell 151 and the arc-shaped pass plate 14. According to actual test requirements, these hot flow gases can be returned to the interior of the detection box 11 or directly discharged to the outside.

[0037] When each layer of the one-way rotating plate 152 of the layered side shell 151 is closed, the gas passing through the detection box 11 will be separated by the one-way rotating plate 152, and each layer of gas comes from the space where the electrical station 3 is located in a different area, and then the temperature of each gas can be detected by the temperature measuring tube 153 of each layer, so as to judge the heating condition of the motor and the actual ambient temperature.

[0038] Since the gas passed into the segmented gas cylinder 54 from bottom to top will be diverted to the interior of the detection box 11 through the adapter tube 55, in order to control the exhaust effect of the drainage device 5, the clustering slide 22 on the corresponding side can be pushed horizontally by the traction rod 23, so that the filling temperature measuring rod 24 can be inserted into the interior of the adapter tube 55. On the one hand, by blocking the adapter tube 55, the segmented gas cylinder 54 at a specific position is prevented from discharging hot air to the interior of the detection box 11. On the other hand, the temperature sensing function of the filling temperature measuring rod 24 can be used to monitor the temperature of the area where the electrical station 3 is located, thereby testing the heat emitted by the normal operation of the motor in this area.

[0039] Example 2, please refer to Figure 1-Figure 8The present invention provides a technical solution: on the basis of the first embodiment, the electrical stand 3 includes a heat insulation board 31, a partition frame 32 is evenly arranged on the upper surface of the heat insulation board 31, and a conducting device 33 is symmetrically arranged on the front and rear sides of the inner wall of the partition frame 32. The top of the conducting device 33 is fixedly connected to a torsion motor 35 through a rotating rod, and the bottom end of the conducting device 33 is fixedly connected to a power supply tube 34 through a wire 332. The conducting device 33 includes a rotating shaft 331, a large housing 333 is fixedly connected to the front of the rotating shaft 331, and a small housing 334 is fixedly connected to the back of the rotating shaft 331. The large housing 333 and the small housing 334 can provide adaptive current according to different types of motor connectors. The top of the wire 332 is rotatably connected to the bottom of the inner cavity of the rotating shaft 331, and the outer surface of the wire 332 is fixedly connected to the top of the inner cavity of the insulation board 31 through a through hole. The electrical station 3 is arranged between the areas separated by the detection box 11, and each electrical station 3 is centrally provided with seven groups of insulation boards 31, so that more motors can be detected at the same time.

[0040] The bottom of the insulation board 31 is fixedly connected to the inner wall of the detection box 11, the inner cavity of the power supply tube 34 is fixedly connected to the inner cavity of the detection box 11 through the power supply line, the upper surface of the torsion motor 35 is fixedly connected to the inner wall of the detection box 11, and the lower surface of the partition frame 32 is fixedly connected to the upper surface of the insulation board 31.

[0041] The switching device 4 includes a plug-in hollow plate 41, the bottom end of which is fixedly connected to a guide shaft 42, the front and rear sides of the axis of the guide shaft 42 are fixedly connected to a switching rotating machine 43, the inner cavity of the plug-in hollow plate 41 is fixedly connected to an embedded diverter shell 44, the left and right ends of the embedded diverter shell 44 are fixedly connected to a connecting soft sleeve 45, the bottom end of the connecting soft sleeve 45 is fixedly connected to an embedded bottom shell 46, and the embedded diverter shell 44 is a cross-shaped structure as a whole, which is used to connect the interior of the plug-in hollow plate 41 and the interior of the connecting soft sleeves 45 on both sides.

[0042] The outer surface of the embedded bottom shell 46 is fixedly connected to the bottom of the inner cavity of the detection box 11, the bottom end of the communicating soft sleeve 45 is connected to the interior of the embedded bottom shell 46, the left end of the plug-in hollow plate 41 is plugged into the bottom of the inner wall of the arc-shaped through plate 14, and the outer surface of the guide shaft 42 is rotatably connected to the bottom of the inner wall of the detection box 11.

[0043] The motor is placed inside the partition frame 32, and its terminal heads at both ends are respectively connected to the conductive devices 33 on both sides to realize the power supply of the motor. Due to the different models of motors, there may be problems such as insufficient power supply voltage. Therefore, two shells, one large and one small, are set on the front and back sides of each rotating shaft 331. The required motor components are powered by rotating and switching through the torsion motor 35 on the top.

[0044] The switching rotating machine 43 at the bottom can control the guide shaft 42 of its output shaft to rotate. When the guide shaft 42 twists and plugs the hollow plate 41 to rotate to a horizontal state, that is, Figure 8 In the state shown, the left end of the plug-in hollow plate 41 will be inserted into the bottom of the arc-shaped plate 14. At this time, the gas flowing back from the inside of the arc-shaped plate 14 will be plugged into the hollow plate 41, the embedded diversion shell 44 and the connecting soft sleeve 45 in sequence, and then directly discharged to the outside, so as to dissipate heat inside the device and avoid heat accumulation inside the detection box 11; when the guide shaft 42 twists the plug-in hollow plate 41 to separate the top of the plug-in hollow plate 41 from the arc-shaped plate 14, the detection box 11 is in a state of being connected to the outside world. Therefore, under the extraction action of the ventilation pump 13, the cutting device 4 can realize the air intake work, thereby increasing the gas flow rate charged by the ventilation pump 13.
