[0026] according to Figure 1-9As shown, a portable detection device for automatic door motors in rail vehicles includes a storage box 1. A detection mechanism is installed inside the storage box 1. The detection mechanism includes a placement box 2. A fixing component is fixedly installed inside the placement box 2. The fixing component is used to fix the motor to be tested. A top cover 3 is fixedly installed on the top of the storage box 1. A control element is installed on the top cover 3. A box cover 4 is rotatably installed on the top of the storage box 1.

[0027] In the above specific embodiment, during testing, the motor to be tested is placed in the placement box 2 and fixed by a fixing component to facilitate subsequent testing work. The motor detection mechanism is installed in the storage box 1 so that the staff can carry it with them for testing, thereby eliminating the need to transport the motors in batches, which is conducive to improving the flexibility during testing and realizing a full inspection acceptance method to avoid the occurrence of problematic motors being missed.

[0028] In this embodiment, according to Figure 4-6 and Figure 9 As shown, the detection mechanism also includes a power supply 5, a brushless motor driver 6 and a base plate 7. The power supply 5 and the brushless motor driver 6 are fixedly mounted on the top of the base plate 7. The power supply 5 is electrically connected to the brushless motor driver 6. A power interface 8 is fixedly mounted on the bottom end of the side wall of the storage box 1. The power interface 8 is electrically connected to the power supply 5. A first interface 11 is fixedly mounted on the inner wall of the placement box 2. The first interface 11 is electrically connected to the brushless motor driver 6. Several groups of first connecting columns 9 are fixedly mounted on the bottom of the base plate 7. Several groups of second connecting columns 10 are fixedly mounted on the bottom inner wall of the storage box 1. The second connecting columns 10 is fixedly connected to the first connecting column 9, and the control elements include a first switching switch 14, a second switching switch 15, a speed adjustment knob 16, a tachometer 17 and a second interface 18. The first switching switch 14, the second switching switch 15, the speed adjustment knob 16, the tachometer 17 and the second interface 18 are respectively fixedly mounted on the top cover 3. The tachometer 17 is connected in parallel with the first switching switch 14 and the speed adjustment knob 16. The first switching switch 14 and the speed adjustment knob 16 are respectively electrically connected to the brushless motor driver 6, and the second switching switch 15 is respectively electrically connected to the second interface 18 and the power supply 5.

[0029] In the above specific embodiment, first connecting columns 9 are installed on the bottom inner wall of the base plate 7 near the four end points and the center. The base plate 7 is supported and fixed with the cooperation of the first connecting column 9 and the second connecting column 10. A power supply 5 and a brushless motor driver 6 are installed on the base plate. A matching power cord is plugged into the power interface 8. The power supply 5 converts the AC 220V current into a DC 24V current to provide power for the brushless motor driver 6 and the motor to be tested. The first interface 11 is connected to the motor phase line port and the Hall signal port of the brushless motor driver 6 through a wire. The control signal port of the brushless motor driver 6 is connected to the first switching switch 14, the speed adjustment knob 16 and the tachometer 17 through a wire. The second interface 18 is connected to the second switching switch 15 through a wire. The second switching switch 15 is connected to the motor phase line port and the Hall signal port of the brushless motor driver 6 through a wire. The wire is connected to the power supply. When the motor to be tested is a brushless motor, since it is necessary to detect the real-time speed of the motor, the power cord of the brushless motor needs to be plugged into the first interface 11 for testing. The first switching switch 14 has three gears, which correspond to the forward rotation, reverse rotation and stop of the motor respectively. By adjusting the speed adjustment knob 16, the value of the tachometer 17 is observed to see whether it corresponds to the adjusted speed, so as to detect the brushed motor. When the motor to be tested is a brushed motor, the brushed motor does not need to be speed-regulated. It is only necessary to detect whether the brushed motor can rotate normally when powered on. Therefore, the power cord of the brushed motor is plugged into the second interface 12 for testing. The second switching switch 15 has the same structure as the first switching switch 14. The direction of the motor is controlled by the second switching switch 15 to detect whether the brushed motor is normal.

[0030] In this embodiment, according to Figure 5-8 As shown, the placement box 2 is fixedly mounted on the bottom plate 7, the top of the placement box 2 is rotatably mounted with a box cover 12, and a handle 13 is fixedly mounted on the box cover 12.

The slide groove 193 is provided in the bottom rod of the fixed clamping claw 19. A connecting rod 20 is slidably installed, and a movable clamping jaw 22 is fixedly installed on the end of the connecting rod 20 away from the fixed clamping jaw 19. A button seat 23 is fixedly installed on the end of the slide groove 193 close to the movable clamping jaw 22. A spring 24 is installed inside the button seat 23. A button 25 is movably installed on the end of the button seat 23 close to the slide groove 193. The two ends of the spring 24 are fixedly connected to the button seat 23 and the button 25 respectively. The bottom end of the button 25 is an arc-shaped structure. Several groups of snap-in grooves 21 matching the buttons 25 are arranged in an array on the top wall of the connecting rod 20.

[0031] In the above specific embodiment, the detection requirements for brushless motors are higher than those for brushed motors. In order to ensure the accuracy of brushless motor detection, the brushless motor is placed in the placement box 2 for detection. The placement box 2 is equipped with multiple sets of jaws for fixing the motor. When fixing the motor, the motor is placed between the movable jaw 22 and the fixed jaw 19, and the movable jaw 22 is retracted toward the fixed jaw 19, so that the movable jaw 22 and the fixed jaw 19 are in contact with the side wall of the motor, and with the cooperation of the spring button 25 and the clamping groove 21, the connecting rod 20 is fixed in the slide groove 193, so that the motor is clamped and fixed with the cooperation of the movable jaw 22 and the fixed jaw 19, thereby ensuring the stability of the brushless motor during the detection process to ensure the accuracy of brushless motor detection.

[0032] In this embodiment, according to Figure 4-5 As shown, a noise detector 26 is fixedly installed on the left outer wall of the placement box 2, and a display screen 28 is fixedly installed on the top cover 3.

The interior of the placement box 2 is provided with a groove corresponding to the detection rod 27. The detection rod 27 is located in the groove to avoid touching the detection rod 27 when installing the motor. Sound insulation pads 29 are fixedly installed on the inner walls of the placement box 2 and the box cover 12.

[0033] In the above specific embodiment, in some usage scenarios, there are higher requirements for the noise of the motor, so the noise of the brushless motor during operation is monitored. When testing the brushless motor, a closed space is formed in the placement box 2 by closing the box cover 12, and the external noise is isolated by the sound insulation pad 29. After the motor is started, the noise detector 26 is used to monitor the noise of the motor during operation, and the monitoring results are displayed on the display screen 28.
