Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
A kind of automobile door lock is endured cold detection device, including car door, further include outside door handle 1, open outside lock body pull rod 2,
Mandril conduit 3, cylindrical cam 4, stepper motor 5, mandril 6, infrared transmitter 7, infrared remote receiver 8, single-chip microcontroller 9, relay 10,
Remote controler 11 and buzzer 12；
The stepper motor 5 is connect by conducting wire with automobile storage battery, and is placed in inside car door；
4 bottom of cylindrical cam is connect with 5 output end of stepper motor；
The mandril conduit 3 is internally provided with spring 31；
One end of the mandril 6 is protruded into the mandril conduit 3 and is connect with the spring 31, and ball is provided on the other end
61, the tip contact of the ball 61 and the cylindrical cam 4；
The top of the mandril conduit 3 is fixedly connected with unlatching pull rod 2 outside the lock body；
Pull rod 2 is opened outside the lock body to connect with the outside door handle 1；
The side of the mandril conduit 3 is provided with infrared transmitter 7, and the infrared transmitter 7 passes through conducting wire and the list
Piece machine 9 connects；
It is provided with infrared remote receiver 8 on the inside of car door, for receiving the infrared transmitter when the mandril conduit 3 rises
7 infrared signal；
The single-chip microcontroller 9 is arranged in car body and is connect simultaneously by conducting wire with car antenna 92 and buzzer 12；
The single-chip microcontroller 9 is connect with automobile storage battery and the infrared remote receiver 8 respectively by conducting wire；
The relay 10 is arranged inside car door, is connect by conducting wire with the delivery outlet of the single-chip microcontroller 9；
The relay 10 is electrically connected with the stepper motor 5；
The remote controler 11 includes radio remote-controlled signal generator, transmitting antenna and battery.
The single-chip microcontroller 9 is STM32 chip.
The single-chip microcontroller 9 is electrically connected with automobile door lock defrosting system.
The spring 31 is compressed spring.
Open that pull rod 2 is vertical to be connect outside the top of the mandril conduit 3 and the lock body.
The relay 10 is dynamic circuit connector type electromagnetic relay.
Single-chip microcontroller 9 is powered by automobile storage battery and supports the electricity consumption of infrared transmitter 7 and infrared remote receiver 8 by conducting wire.
When in use, car owner opens central controlled lock by automobile remote controllers, then controls the starting whole system of remote controler 11 of this detection device,
Single-chip microcontroller 9, which is powered, starts to work, and control infrared transmitter 7 is opened and makes 10 access of relay, and stepper motor 5 rotates a circle,
Make mandril 6 at 4 tip motions of cylindrical cam one week, opening pull rod 2 if door lock is frozen in, outside lock body cannot move, and make
The mandril conduit 3 connected with it cannot move up and down, when mandril 6 is moved to cylindrical cam top highest point, during this
31 largest deformation amount of spring is L1.Infrared transmitter 7 does not move up, and at this moment infrared remote receiver 8 does not receive signal, says
Bright automobile door lock is frozen in, and single-chip microcontroller 9 feeds back to car owner by buzzer 12, and car owner can start the beam worker to thaw in advance
Make.If automobile door lock is not frozen in, during mandril 6 rises, the active force of spring 31 makes mandril conduit 3 and lock
External pull rod 2 of opening moves upwards, and as mandril 6 continues to move up, 31 pushing drawing rod of spring completes unlocking process, at this moment bullet
Spring largest deformation amount is L2, it is clear that L2 < L1, as mandril conduit 3 moves upwards, infrared remote receiver 8 receives signal simultaneously
