Door handle. A device mounted on the inside or outside of a car door to open or lock the door
Hand in hand travel. The linear or curved distance that the handle drives the cable movement 2 Function, principle and structure of the handle inside and outside the door
Door inside and outside handle function. The door handle opens and locks the door. Ensure customer safety, and decorate the appearance of the function. Door handle is installed on the inside of the door, used to unlock or lock the door, and open the door.
The structural form and working principle of the door inner and outer handles.
Door handle structure. Car door handle is divided into external pull type and external lift type structure. The pull type handle can be divided into integrated type handle and split type handle according to its appearance. The external handle assembly consists of a handle, a base, a gasket and a lock core. The base of the external handle is mainly composed of the base skeleton, opening arm and counterweight block, pin shaft, torsion spring, spool valve and other components. The base structure can also add an inertial lock to improve the safety of the external handle in the collision process. The outer pull handle assembly is mainly composed of a lock cover, a handle upper cover, a handle lower cover and a gasket. According to the modeling and functional requirements, induction antenna, decorative strip and other components can be added.
Working principle of door handle. Working principle of the outward pull handle: the front and rear door handles are fixed with the door plate through the buckle at the back of the base, the front section is fastened to the door plate through an installation bolt, and the outer handle is fixed to the door gold. Pull the handle around the rotating shaft 1 Rotate the handle hook to drive the opening arm to rotate around the rotating shaft 2, and the ball head of the pull wire on the opening arm moves and generates motion stroke. When the pull line stroke reaches the unlock stroke, the door lock opens. Working principle of the external lift handle: the base of the external lift handle is fixed with the car door plate through bolts; The handle and the base form a rotating motion pair through a rotating shaft. The mounting buckle is rigidly connected with the opening handle. The mounting buckle is fixed with the connecting rod of the lock. At the same time drive the buckle movement; The main function of the spring is to reverse the opening handle. Through this mechanism, the force is transferred to the connecting rod of the lock, and the specific opening stroke is determined according to the stroke of the connecting rod of the lock.
