The two ends of the connecting rod 707 are respectively mounted on the electronic tension sensor 716 and the push block 702. Finally, the rear baffle 711 is installed behind the support profile 710.

[0057] Work process:

[0058] Place the door lock on the door lock fixing mechanism 6, align the mounting hole with the screw 6510, press the lock button on the panel 102 until the motor 6501 stops rotating, then release. Insert the wiring harness interface into the door lock socket. Hook the inner opening cable onto the cable connecting bracket 31 of the inner opening mechanism 3, and the inner locking cable onto the cable connecting bracket 31 of the inner locking mechanism 4. If there is an inner locking function, insert the locking pin 214 of the outer opening mechanism 2 into the outer opening rocker arm hole of the door lock, and insert the connecting rod 52 of the outer locking mechanism 5 into the outer locking rocker arm hole of the door lock. After completion, press the start button on the panel 102 to start the program. Inspection steps:

[0059] 1. The system will first check whether the signals at each position of the door lock are normal. If it finds that the wiring harness is not plugged into the door lock, or the door lock is locked, it will detect that the signal is abnormal, start the alarm and stop running.

[0060] 2. After the signal is normal, the latch and reaction force mechanism 7, the locking pin 701, is pushed into the fully locked position in the lock body, and the electric unlocking and locking test begins. If the electric unlocking and locking action cannot be completed, the test panel will alarm and stop operating.

[0061] 3. After the electric unlocking and locking tests are passed, the outward opening stroke is tested. The outward opening mechanism 2 moves to the minimum outward opening stroke position on the first layer. At this time, it is required that the door lock cannot be opened. If the door lock is opened at this time, the test platform will alarm and stop running. If it passes the second layer, it moves to the maximum opening stroke position. The door lock is required to be opened. If the door lock is not opened, the test platform will alarm and stop running.

[0062] 4. After the outward opening test is passed, the locking cylinder 701 has been retracted. Then the locking cylinder 701 will be pushed back into the lock body to enter the half-lock position and check the door light signal. If it is normal, it will enter the fully locked position. If the signal is abnormal, the alarm will start and the operation will stop.

[0063] 5. When the locking cylinder 701 enters the fully locked position, the inward opening stroke is tested. Similarly, the inward opening mechanism 3 moves to the minimum outward opening stroke position on the first layer. At this time, it is required that the door cannot be opened. If the door lock is opened at this time, the detection platform will alarm and stop running. If it passes through the second layer, it will move to the maximum opening stroke position. The door lock is required to be opened. If the door lock is not opened, the detection platform will alarm and stop running.

[0064] 6. After passing the previous steps, the locking cylinder 701 will re-enter the fully locked position and begin testing the external locking function. The first layer of the external locking mechanism 5 will move to the locked position and then return to its original position. The external opening mechanism 2 will perform the external opening operation. At this time, the door cannot be opened because the door lock is already locked. Then, the second layer moves in the opposite direction to unlock the door lock. At this time, the external opening mechanism 2 will perform the external opening operation again. The external opening should be able to open at this time; otherwise, the test panel will alarm and stop operating.

[0065] 7. (If the door lock has an internal locking mechanism, then perform this step) The internal locking movement steps are the same as the external locking;

[0066] 8. Finally, perform the anti-mislock function test. When the lock cylinder 701 is not in the fully locked position, the electric operation should be unable to lock. Otherwise, the test panel will alarm and stop operating.

[0067] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.

9. A testing platform for automatically detecting door lock functions according to claim 1, characterized in that: It also includes an inner locking mechanism (4), which is connected to the pull cable of the lock body. The inner locking mechanism (4) is used to drive the lock body to the locking position and the unlocking position, and cooperates with the outer opening mechanism (2) to perform the outer opening to determine whether the lock body is in the corresponding locking and unlocking state. The inner locking mechanism (4) consists of two sets of cylinder connection mechanisms connected in opposite directions and a second cable connection bracket (41), with the second cable connection bracket (41) fixed on the uppermost layer of the two sets of cylinder mechanisms.
