The mechanism to open the door of your padlock sounds actually very interesting, it must be very reliable as a car born to perform tens of thousands of times keyless operation. When reading the lines below as the best remote starters, you will know what is required to lock the doors to open and close.
The door can be locked using the keyboard, not the key locking system (keyless entry), mechanical locking system or systems normally combine these methods again, and even cars can now have 4 to 6 how to lock the door. With modern locking systems, simply one press is very simple to open, but what will happen in the rather complex structure?
- The lock and unlock with common methods
There are 6 common ways to unlock the lock and on cars: By the keys, by pressing the “unlock” in the car, with the key code (of course) outside, by pulling the top knob, inside door car, with remote control, by signals from the control panel.
Some vehicles with electric door locks, switches “lock” and “unlock” actually send electrical signals to the actuator to unlock the door. However, some systems have better coherence, which should have more ways to lock and open the door and center console blocks that will decide when to open the car door.
Central control block is a computer in your car. It covers both the smallest ones to make your car friendly. For example, it controls the lights in the car until morning to start the car or it prompts you with the word “beep” when to forget the headlights or the key in the lock.
In case of power door locks, control units monitor all signal sources “lock” and “unlock”. It will monitor all the impacts of open code and automatically open when getting accurate numbers. The system also detects radio frequency and automatically open when it receives the exact code from the signal in your hand and it also checks the switch inside the car. Upon receiving a signal from any source, it will supply power to the actuator is closed, then open the car door.
- The structure of the door locking system
In this car, actuators, power door locks are installed under the car door closing. A stiff rod is connected to the latch mechanism, and the other a stick is connected with a knob latch rising up above the car door.
When the latch mechanism to move up, it connects with the outside door handle to open completely mechanically. When closing the trap door, the outside door handle is not connected to the system in terms of mechanics, which can not open the car door. To unlock, control units supplied with power for the locking mechanism in a moment.
- Inside the structure
The system is quite simple. A small electric motor to rotate a series of cylindrical gears to reduce speed. Final gear rack drive a strut connecting hardware. Rack convert rotary motion of the electric motor into linear motion to move the bolt.
One other interesting thing about this structure is the electric motor can rotate the gears and shifts the lock latch. But if you lift the latch on the electric motor that can not turn anymore. This is done by an automatic clutch connects the centrifugal gear with electric motors.
When the electric motor turns the gears, the clutch connects the small metal gear with a larger plastic gears, allowing the electric motor linked to the latch. If you pick up the key, all the gears are spinning, but the pie is only so clutch plastic teeth clenched in it.
Sometimes you accidentally forget your keys in the car and lock the hatch again, you need to know a tool to unlock very effective: thin metal strip with a flat trailer (can use the small coat the aluminum trailers). A vertical motion from any open hand or electric lock mechanism latch key impact is all that is needed to open and close the lock. The unlock will end when the metal strips that touch points open hand or power lock structure to connect to. That is all that is the crux of the door locking system.
