Car rear door limiter function
The main functions of the car rear door limiter include the following aspects :
Limit the maximum opening of the door : The door stopper can limit the maximum opening of the door to prevent the door from opening too large, which is convenient for people to get on and off the car, and meets the ergonomic and safety requirements. For example, the maximum opening of the front and rear doors of FAW Toyota Corolla under the action of the limiter is 63°, which is convenient for people to get on and off the car, and ensures safety .
Keep doors open : Door limiter can keep doors open when needed, especially when the vehicle is parked on a ramp or in windy weather, to prevent doors from automatically closing or opening too wide due to wind or ramp influence. For example, the front door of the Corolla can be held open at three degrees of small half, half and full, and the back door can be held open at two degrees of half and full .
Protect the door and body : Door limiter protects the front door frame from contact with the body sheet metal to avoid scratching and damage. In addition, in windy weather, especially when the vehicle is open downwind, the door limiter can play a protective role to prevent the door from being damaged by excessive wind .
Characteristics and applications of different types of door stoppers :
rubber spring type : the limiter deforms the elastic rubber block through the movement of the limiter bracket and the limiter box, and uses the limiter arm structure to realize the limiting function. Its structure is diverse, but the sheet metal requirements are high, and the insufficient strength of the hinge may lead to the door sinking and abnormal ringing. Common models such as Nissan Sylvie, Emgrand GL, Volkswagen lavida, etc. are equipped with this type of limiter .
torsion spring : this kind of limiter is integrated with hinge. It realizes the function of limiting through torsion bar deformation. It has low noise, long life and good limiting effect, but it occupies large space, has complex structure and high maintenance cost.
The main function of the Door check is to limit the extent to which the door is opened and ensure that the door moves within a safe range.
Definition and function
The main functions of the door opening limiter include:
Limit the maximum opening of the door , prevent the door from opening too large, avoid the door plate and car body contact .
keep the door open and keep the door open when needed, such as on ramps or when it is windy, the door will not close automatically .
Type and structure
Common door opening stoppers include the following types:
pull band limiter : This is a self-contained limiter commonly used to limit the full and half open position of a car door .
box limiter : also known as split type limiter, simple structure, low cost, widely used in most cars .
torsion bar and spring stoppers : These stoppers are usually integrated with door hinges and belong to the category of door all-in-one hinges .
Installation position and working principle
The door stopper is fixed on the car body through the mounting bolt, and the stopper box is fixed on the door through the mounting screw. When the door is opened, the stop box moves along the track of the stop arm and limits the door opening by the roller in the stop box touching the stop rod protrude .
This design ensures that the doors remain within the set Angle range when opened, while providing the necessary sense of resistance.
