Embodiment 1

[0038] A child lock structure of a car side door lock, which is arranged between an inner opening mechanism and an outer opening mechanism in the car side door lock body, and controls the position of the inner opening mechanism and the outer opening mechanism through two positions of locking and unlocking Detach and combine to fulfill its function;

[0039] The child lock structure includes:

[0040] A child lever operating arm 14 with a preset linear motion stroke, and a child lever linkage plate 15 driven by the child lever operating arm 14 to realize synchronous linear displacement; the two ends of the linear motion stroke are respectively designed to unlock the child lock position and locked position;

[0041] When the external force manipulates the lever operating arm 14 to push the lever linkage plate 15 to the locked position at the same time, the inner opening mechanism is separated from the lever linkage plate 15, making it impossible to indirectly transmit the force...

Embodiment 2

[0047] A car side door lock with the child lock structure described in Embodiment 1, its internal structure mainly includes:

[0048] Child lock mechanism A: child lever control arm 14, child lever linkage plate 15;

[0049] Locking mechanism B: locking bracket 1, mounting base plate 2, rotating pallet rivet 3, rotating pallet 4, rotating pallet torsion spring 5, washer 6, stop claw rivet 7, stop claw 8, stop claw twist Spring 9;

[0050] Locking / unlocking mechanism C: locking lever 10, locking lever torsion spring 11, lower housing 12, upper housing 13;

[0051] Inner opening mechanism D: an inner opening arm 16 pivotally supported by the lower housing 12 and capable of rotating with the door opening operation of the inner door handle;

[0052] Other mechanisms: external opening mechanism 17;

[0053] Child lock unlock position: the child lever operating arm 14 is in the unlock position, allowing the child lever linkage plate 15 to rotate together with the inner opening ar...

Abstract

The invention relates to a child lock structure of an automobile side door lock. The child lock structure is arranged between an inner opening mechanism and an outer opening mechanism in a lock body of the automobile side door lock. The inner opening mechanism and the outer opening mechanism are controlled to be separated and combined through the locking position and the unlocking position, and therefore the function of the child lock structure can be achieved. The child lock structure is characterized in that the child lock structure comprises a child rod operation arm with a preset linear movement stroke, and a child rod linkage plate driven by the child rod operation arm to synchronously and linearly move; and one end of the linear movement stroke is designed to be the unlocking position of a child lock, and the other end of the linear movement stroke is designed into the locking position of the child lock. The child lock structure is simple and reasonable in structural design, the function of the child lock is achieved through cooperation of the child rod operation arm, the child rod linkage plate, a lower shell body, an upper shell body, the inner opening mechanism, the outer opening mechanism and other parts, and therefore peril incidents caused by the phenomenon that children on the back row touch an opening handle inside an automobile by accident and open a rear automobile door can be effectively prevented.

Description

technical field [0001] The invention relates to an automobile side door lock, in particular to a child lock structure of an automobile side door lock, and belongs to the technical field of automobile lock structures. Background technique [0002] At present, there are more and more car side door lock functions, which are not only satisfied with the common functions, such as lock / unlock, lock / unlock, etc. Among them, the child lock function is a more practical function, which is generally used in the door lock of the rear position of the car. The purpose is to prevent the children in the rear row from opening the rear door by accidentally touching the opening handle in the car while the car is driving, resulting in dangerous accidents; the child lock function is born from this, which can keep the child lock locked after the rear door is closed. Therefore, the door cannot be opened through the inner opening handle to ensure the safety of children in the rear row. [0003] H...
