Because on the existing cars, some models use self-priming door locks. The self-priming door lock relies on a motor device to drive the self-priming mechanism inside the lock body to withstand the card plate inside the lock body, so that the card plate can move to the lock body autonomously. The fully locked engaged position moves until the door is fully locked.

However, often for self-suction door locks, due to the addition of a self-suction mechanism, the self-suction mechanism needs to introduce multiple parts, which are connected together by hinges. board to match. Since the internal card plate, claw and other parts of the door lock reciprocate along its fixed axis during the unlocking and locking process, after the self-suction mechanism is added, the mechanism needs to participate in the card plate during the self-suction process. During the movement of the claw, however, during the unlocking process, the movement of the clamping plate and the claw cannot be interfered or interfered by the self-suction mechanism. Therefore, in the existing design scheme, the self-suction mechanism is fixed. In the vicinity of the card board, a connecting arm is switched, and a push arm is connected, so that the self-suction mechanism is in a retracted state when unlocking, and is in an extended state when self-suction is closed. To realize this process, the prior art , at least 3 new parts need to be added, in order to ensure its stability, 5 parts may be introduced (additional 2 additional parts are auxiliary positioning parts). In this way, the volume of the lock body will increase, the number of parts will increase, and the assembly complexity will also increase, resulting in increased difficulty in quality control.

Example 2

The second embodiment of the present invention provides an automobile door lock 20, including the self-suction mechanism 100 provided in the first embodiment.

FIG. 7 is a schematic structural diagram of the automobile door lock 20 in a locked state, and FIG. 8 is a structural schematic diagram of the automobile door lock 20 in an unlocked state. Please refer to FIG. 7 and FIG. 8 for details.

The car door lock 20 includes a self-suction mechanism 100 and a locking mechanism. The self-suction mechanism 100 can drive the pull wire 21 through the motor, pull the push arm 15, and drive the clamping plate 18 to rotate relative to the bottom plate 11, so that the locking mechanism inside the lock body It can be locked autonomously without the help of other external forces. The locking mechanism is mainly to maintain the mechanical and reliable locking of the lock body.

The self-suction mechanism 100 also includes a clamping claw 22, which is engaged with the clamping plate 18 and is arranged at a corresponding position on the bottom shell. The working process of the automobile door lock 20 is as follows: the number of rotating shafts is two, and one of the rotating shafts passes through in sequence. Through the card plate 18, the push arm 15 and the bottom plate 11, another rotating shaft passes through the clamping claw 22 and the bottom plate 11 in turn. There is a return torsion spring (specifically, a torsion spring, not shown in the figure), and the clamping plate 18 and the clamping claw 22 can perform a reciprocating rotational movement in a certain range around the rotating shaft. The card plate 18 forms an engaging relationship with the lock catch 24, which can keep the locking of the lock body.

The push arm 15 is installed on the bottom plate 11 through a rotating shaft, and the end of the push arm 15 away from the rotation adjusting portion 152 is provided with a return spring 23 and a pull wire 21, wherein the return spring 23 is stretched toward one side of the push arm 15, so that the push arm 15 is always Under the pulling force of the spring, the movement to the side of the bottom plate 11 is finally stopped by the limit. The pull wire 21 is stretched toward the other side of the push arm 15 , that is, the pull wire 21 and the return spring 23 face two opposite directions respectively. The pull wire 21 provides input power for the push arm 15 to pull the push arm 15 to rotate.

Referring to FIG. 8 , the latch 24 is completely disengaged from the locking mechanism, the clamping plate 18 is not engaged with the clamping claw 22 , the push arm 15 is pulled by the return spring 23 , and the second engaging portion 156 is located on the bottom plate 11 . The uppermost end of the track slot 12, and the second engaging portion 156 of the push arm 15 moves along the track slot 12, so that the first engaging portion 154 on the push arm 15 is in a released and disengaged state from the card board 18, and the card board 18 can Free rotational movement relative to the base plate 11 .

When the locking mechanism moves to the semi-locked state, the self-suction position is triggered. Since the half-lock state is a required unique state in the car door lock 20, the car door lock has 2-speed locking, and the half-lock is the first-speed locking state at the beginning of the closing process. When the lock body is in the fully open position to the half-lock position, it relies on external force to drive the door, so that the door lock is closed in the half-lock position. Generally, due to the waterproof and NVH requirements of the sealing strip of the car door, when the door is locked in the half-lock, the door is not locked. Fully compress the door sealing strip, so the process of the door from fully open to half-lock is easy to achieve without too much reaction force and resistance.

However, in the process from half-locking to full-locking, the door begins to press the sealing strip, the reaction force and resistance of closing the door increase, and it cannot be fully locked easily. It is precisely because the half-lock is easy to achieve, so the starting point of the self-suction trigger is set at the half-lock position or a position just before the half-lock.

At this time, there is a micro-switch signal that triggers the internal mechanism, giving the ECU a command to the motor, and tightening the push arm 15 through the pull wire 21. The oblong hole on the push arm 15 does not completely limit its degree of freedom, and the push arm 15 will move along the The first engaging portion 154 on the push arm 15 engages with the engaging groove 183 on the clamping plate 18, and then the push arm 15 moves together with the clamping plate 18, and finally the push arm 15 moves together with the clamping plate 18. The arm 15 is moved to a position in engagement with the pawl 22 . Other signals are then triggered to reverse the motor and release the push arm 15.

The push arm 15 will be acted on by the restoring force of the return spring 23 and return to the initial position. The purpose is to release the first engaging portion 154 on the push arm 15 to the engaging groove 183 on the card plate 18, which can be When unlocking, the card plate 18 can smoothly move in the unlocking direction.

The car door lock 20 has a reasonable design and a simple structure. It integrates and optimizes the existing door lock, reduces the number of parts, facilitates assembly, ensures that the entire set of mechanisms can operate effectively and reliably, and completes a set of complex actions through a set of simple mechanisms. Strong practicality.

It should be noted that the features in the embodiments of the present invention may be combined with each other under the condition of no conflict.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
