What are the door handles inside the front and rear doors of a car
The front and rear door handles inside the car are mechanical devices used to open and close the car doors. They are usually composed of metal or plastic handles and connecting mechanical structures. Some high-end models also integrate intelligent functions such as keyless entry.
Basic functions
The inner handle is located on the inner side of the door. The driver and passengers control the opening and closing of the door by pulling the handle. It is mostly made of metal or plastic, taking into account both durability and lightweight requirements.
Design differences
Mercedes-benz: The handle shapes of the C-Class, E-Class and S-Class models are similar, but the materials and functions improve with each class (for example, the S-Class is equipped with an electronic lock button).
Volvo: The interior handle structure of models such as XC90 and S90 is uniform, and some adopt a semi-transparent wrapped spring design, providing a strong damping effect.
Domestic cars, such as Chery Tiggo 8 PLUS, have a smooth rebound process when pulling the handle and a dull sound when closing, reflecting a high-end texture.
Opening method
Common types include rotary, push-pull, electric and concealed types. Some models support the switching between manual and electric dual modes.
The door handles inside the front and rear doors of a car are mainly used to open and close the car doors, and they also have functions such as stabilizing the body and assisting in reversing.
Door opening and closing function
The door handle inside the door is connected to the door lock pull rod through a mechanical structure. When pulled, the door can be opened or closed. Some high-end models also integrate intelligent functions such as keyless entry.
Stabilizing the body
The handles inside the vehicle are designed on both sides of the front and rear seats, allowing passengers to hold them to maintain body stability, especially providing support during sudden braking or jolting.
Auxiliary reversing function
When reversing, one can observe the relative position between the inner handle and the curb to assist in judging the distance between the rear of the vehicle and enhance safety.
Materials and Design
Common materials include engineering plastics such as TPE and PVC or metals, which balance durability and lightweight. The design pays attention to coordination with the interior style, and some models adopt a three-dimensional shape.
