The function of the handle inside the front door of a car
The inner handle of the front door of a car is mainly used for opening and closing the car door, and it also has safety functions such as escape and child lock. The following are the specific functions:
Open and close the car door
The door is opened and closed by mechanically connecting the door lock pull rod. Common materials include engineering plastics such as TPE and PVC, as well as metal snap structures.
Escape function
In an emergency, the car door can be unlocked by pulling the handle by hand, which complies with the mandatory safety requirements of the Ministry of Public Security for mechanical handles.
Child lock function
Some models are equipped with child locks to prevent children from accidentally touching the door handle to open the car door.
The inner handle of the front door of a car is a mechanical device located on the inner side of the door. It is mainly used to pull the door to achieve the opening and closing function when the driver and passengers get on or off the car. Its core function is to control the opening and closing of the car door through a physical connection structure, and it may integrate additional functions such as child locks and keyless entry.
Function and Structure
Basic function: By pulling the handle, the mechanical structure is triggered to open or close the car door.
Additional features: Some models are equipped with child locks (to prevent children from mistakenly opening the door) and keyless entry (automatically unlocking with a smart key), etc.
Materials and Design
Material: Commonly found in ABS+PC plastic (balancing lightweight and durability), high-end models may adopt metal electroplating or piano lacquer processes to enhance the texture.
Design differences
Rotary type: Press and rotate the button before pulling.
Push-pull type: You need to press the button down first and then pull.
Hidden type: Some luxury models adopt a hidden design, which requires pressing specific areas to trigger the pop-up.
Precautions for Use
Regular inspection: Avoid getting the handle stuck or broken to ensure the mechanical structure is flexible.
Child lock operation: After activating the child lock, the car door can only be opened from the outside.
Fault handling
If the handle gets stuck or breaks, the interior panel needs to be removed and the entire component replaced. Regular inspections can prevent potential safety hazards.
