Description

Technical Field

[0001] This utility model relates to a vehicle door testing platform, specifically a mobile vehicle door testing platform. Background Technology

[0002] The door system is a crucial component of subway trains, requiring frequent opening and closing during operation. A malfunction can significantly impact train operation and passenger comfort. During major train overhauls, the maintenance and testing of the door system is a primary focus. After maintenance, the door system undergoes a series of tests. According to current overhaul regulations, post-maintenance door functionality tests include door opening and closing pressure tests, door opening and closing time tests, obstacle avoidance tests, and emergency unlocking tests. All of these tests must be performed manually, item by item.

[0003] The existing technology has the following problems:

[0004] 1. The door testing process requires manual operation of each item, and the test data needs to be filled in manually, which is inefficient.

[0005] 2. There are no specific testing methods for the door motor and door controller, making it impossible to determine the status of the door's electrical components. Utility Model Content

[0046] Figure 2 This is a three-view drawing of the movable housing 1 of the mobile door test bench according to a preferred embodiment of the present invention. The material of the movable housing 1 is aluminum alloy.

[0047] The main control space 11 and the test module space 12 have interfaces and are connected to the main control computer 21 and the door test module via connecting cables.

[0048] The door testing module is connected to the main control computer 21 inside the mobile housing 1 via a data cable and interface.

[0049] The manual door closing pressure testing unit 22 includes an anti-pinch fixture, a push-pull sensor 221, and a handheld device. The push-pull sensor 221 contacts the door leaf through the anti-pinch fixture. The data generated during the push-pull process is transmitted to the main control computer 21 inside the mobile housing 1 through the handheld device and data cable.

[0050] Specifically, an anti-pinch fixture is first placed on the door leaf. Then, using the push-pull sensor 221 and a handheld device, the anti-pinch fixture is pushed to generate data, which is then transmitted to the main control computer 21 via a data cable. The manual door closing pressure testing unit 22 is more convenient and labor-saving compared to using traditional suction cups and spring balances for testing.

[0051] The electric door closing pressure testing unit 23 includes a door clamping force sensor 231 and a handheld device. The door clamping force sensor 231 detects the closing pressure during the door closing process and transmits the data to the handheld device and the main control computer 21 inside the mobile housing 1 via a data cable. Specifically, the door clamping force sensor 231 transmits the squeezing force generated on the passenger compartment door during closing to the main control computer 21 via the handheld device and data cable connected to the sensor.

[0052] The door opening / closing time testing unit 24 includes a door opening / closing position detection fixture, a photoelectric sensor 241, and a door opening / closing test control box. The door opening / closing test control box controls the opening and closing of the vehicle door, and the photoelectric sensor 241 records the time of the door opening / closing action. This time data is then transmitted via a data cable to the main control computer 21 inside the mobile housing 1. Specifically, the door opening / closing position detection fixture is connected to the door opening / closing test control box, and the fixture is fixed to the door leaf. When the door opens or closes, the photoelectric switch on the detection fixture is triggered, and the recorded time is transmitted to the main control computer 21.

[0053] The motor load speed testing unit 25 includes a tachometer, which records the motor speed and transmits the data to the main control computer 21 inside the mobile housing 1 via a data cable. Specifically, a reflective mark is drawn on the coupling at the front end of the motor. The tachometer is connected to the data cable and aligned with the reflective mark. When the passenger compartment door opens and closes, the tachometer records the speed of the motor coupling and transmits it to the main control computer 21 via the data cable.

[0054] The motor and torque testing unit 26 includes a benchtop electrical parameter measuring instrument and measuring cables. The measuring cables are connected to the motor end and the benchtop electrical parameter measuring instrument to collect resistance and current data of the motor driving the door opening and closing action, and transmit the data to the main control computer 21 inside the mobile housing via the data cable. Specifically, the benchtop electrical parameter measuring instrument is connected to the resistance measuring cable or the current measuring cable, and the measuring cable is connected to the connector at the motor end. By controlling the door opening and closing action, real-time resistance and current are collected and transmitted to the main control computer 21 to determine the motor status.

[0055] The obstacle function testing unit 27 includes an anti-pinch fixture, an electrical parameter measuring instrument, and a current measuring line. The anti-pinch fixture is fixed to the door, and the current measuring line is connected to the electrical parameter measuring instrument. The electrical parameter measuring instrument collects the peak current value when the door encounters an obstacle during closing in real time and generates a line graph. Specifically, the anti-pinch fixture is fixed to the door to be tested, the door control system is activated, the electrical parameter measuring instrument collects the corresponding current value in real time and records the peak value, and finally generates a line graph of the corresponding peak current for 5 times.
