Abstract

The invention belongs to the field of auto parts, and discloses an electric opening branch chain of an automobile door lock with a child lock function, which is composed of a plane 5R mechanism and a space RSCR mechanism. The child lock mechanism consists of a top stop cam, a top stop dial tooth, and a space RSCR Mechanism and swing components constitute. During the electric opening process, the singular position type of the 5R mechanism is used to convert to the 4R motion mode to realize the electric opening of the car door lock. When opening manually, due to the limited movement of the swing crank due to the torsion spring action of the incomplete gear crank, the planar 5R mechanism is transformed into a 4-bar mechanism for compliant and adaptive movement. When the child lock function is enabled, the top stop cam and the top stop shifting tooth are rotated to a specific angle range through the motor control, so that the center point of the S pair of the spatial RSCR mechanism and the plane determined by the R auxiliary axis are perpendicular to the C auxiliary axis; the C auxiliary axis The P pair in the middle is switched to a passive motion pair, and the RSCR mechanism is stiffened, resulting in the locking of the swing crank; the manual inner opening handle is stuck by the blocking lever, and the unlocking dial cannot be pushed, realizing the child lock locking function.

Description

technical field [0001] The invention belongs to the field of auto parts, and in particular relates to an electric opening branch chain of an automobile door lock with a child lock function. Background technique [0002] With the development of smart technology, people's pursuit of car intelligence is becoming stronger and stronger, and the development of smart car door locks with multiple functions is one of them. Based on the existing general car door lock mechanism design technology, it has certain practical significance to develop a new electric door lock with child lock function. [0003] Due to the narrow space of the car door lock, designing a multi-functional car door lock opening mechanism can effectively improve the utilization rate of the space inside the car door lock. [0004] The existing four-bar mechanism cannot realize the multi-mode output of the mechanism, and the five-bar mechanism needs two drives to realize definite motion. Contents of the invention ...
