the output shaft of the motor 10 is a screw, the nut 11 is sleeved on the screw, and when the motor 10 rotates, the nut 11 can move linearly left and right. The tail end of the nut 11 is connected with a pin 14, the pin 14 can move linearly, the upper end of the pull rod 13 is connected to a vehicle door handle 17 through a pull rope, and the pull rod 13 can be pulled to move by buckling the handle 17. The lower end of the pull rod 13 is L-shaped, the lower end of the pull rod 13 is inserted into the pull plate 12, a viscous damping material (polyurethane is selected as the viscous damping material in the positions with thick lines in the figures 2 and 3) is arranged in a sliding channel of the pull rod 13, the lower end of the pull rod 13 presses the microswitch 9, a shoulder used for being hooked by the lower end of the pull rod 13 is arranged on the upper end surface of the pull plate 12, through holes are transversely formed in the pull plate 12 and the pull rod 13, and the pin 14 penetrates through the through holes; the lock catch 15 is hinged on the frame, the bolt 16 is hinged on the frame, the middle of the lock catch 15 is hinged with the lower end of the pulling plate 12, the lock catch 15 is buckled on the bolt 16, and the lock column 19 is positioned in the radial groove of the bolt 16.
The working method of the automobile door lock triggering safety system comprises the following steps:
(1) The pressure sensor 4 senses that a person is in the seat, the system is in an initial state, the pin 14 is kept inserted into the through holes of the pull plate 12 and the pull rod 13, and the lock catch 15 is buckled with the lock tongue 16;
(2) When any person tries to open the vehicle door, the hand is placed in the handle slot 18 in the vehicle door to block the optical signal of the photoelectric sensor 5, the photoelectric sensor 5 sends a signal to the controller 3, and the controller 3 simultaneously sends the following four instructions: (1) the alarm lamp 1 of the rear windshield begins to flash; (2) the alarm 2 in the vehicle carries out voice prompt; (3) the corresponding seat vibrator 6 starts to vibrate; (4) the coil of the relay 7 is powered on to act, the contacts are attracted, the end a of the timer of the IC circuit 8 is triggered, the end b is output, the motor 10 is powered on to work, the output shaft drives the nut 11 to do linear motion leftwards, the pin 14 exits from the through holes of the pull plate 12 and the pull rod 13, the pull rod 17 drives the pull rod 13 to move upwards through a pull rope, the micro switch 9 is switched off, a feedback signal is given to the controller 3, the controller 3 switches off the relay 7, the motor 10 stops (the time t1 that the pin 14 leaves the through holes is less than the time t2 that the pull rod rises, the time t2 is set to be 3s in the embodiment), under the action of viscous damping materials, the pull rod 13 slowly rises, the pull rod 13 reaches the top end, a shoulder of the pull plate 12 is hooked, the pull plate 12 rises to drive the lock catch 15 to rise, the lock catch 15 leaves the lock tongue 16, the lock tongue 16 is free, the lock column 19 leaves a radial groove of the lock tongue 16, and the car door is opened. Therefore, when a door opener pulls the handle, the door cannot be unlocked immediately, and accidents caused by sudden random opening are avoided.
When the door is opened and the handle 17 is reset, the pull rod 13 is returned to the initial bottom position inside the pull plate 12 by a simple mechanical return spring (not shown), and the micro switch 9 is closed again. The IC circuit 8 controls the motor 10 to rotate reversely, and pushes the pin 14 to be inserted into the through holes of the pull rod 13 and the pull plate 12 through the nut 11, so that the mechanical connection is realized again.
When the electronic system component fails and the controller cannot detect the signals of the sensors, the electronic system will not work any more, and the pin 14 is in a pulled-out state, so that the lowest reliability of the system is ensured. However, when the door is opened, the pull rod 13 still slowly rises, the opening of the door still needs a certain time, not instantaneous, and the system is disabled only by the electronic components, so that the safety performance of the opening of the door is guaranteed to the maximum extent.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
