Description

Technical Field

[0001] The utility model relates to the technical field of automotive door locks, and particularly relates to an automotive locking mechanism that saves space. Background Art

[0002] An automotive door lock is a locking device applied to an automotive door. The automotive door is locked tightly through the automotive door lock, and the automotive door lock cooperates with a lock catch arranged on a vehicle pillar to press and lock the door.

[0003] At present, a locking mechanism and an actuating mechanism are provided on an automotive door lock. In order to connect the automotive door lock with an in-vehicle circuit for control, the actuating mechanism currently adopts a more overall design. Generally, the actuating mechanism is connected above the locking mechanism, and a sensor and a controller are provided in the actuating mechanism to transmit signals such as a door light signal and a door control signal. However, this structural design results in a relatively large overall volume of the automotive door lock. Moreover, since door components such as a glass guide groove and a window regulator are also provided above the locking mechanism, the existing automotive door lock cannot be applied and installed on some doors with a compact space. In addition, the damage of a single component requires the replacement of the entire automotive door lock, which will lead to relatively high manufacturing and maintenance costs of the automotive door lock.

[0004] Therefore, the present application provides an automotive locking mechanism that saves space to meet the requirements. Summary of the Utility Model

[0005] The purpose of the present application is to provide an automotive locking mechanism that saves space, which is connected to the actuating mechanism through a split structure, has a more flexible installation method, meets various installation space requirements, and reduces costs.

The transmission member is linked with the unlocking conversion block to control whether the lock tongue can be unlocked. The unlocking conversion block is used to change the transmission state between the unlocking assembly and the lock tongue. The unlocking assembly is connected to an automotive door handle. When the lock tongue is in a locked state and the unlocking conversion block is in a non-unlock position, the unlocking assembly cannot be linked with the lock tongue, and the automotive door handle cannot be used for unlocking, thus achieving the effect of locking the door. When the lock tongue is in a locked state and the unlocking conversion block is in an unlockable position, the unlocking assembly is linked with the lock tongue, and the automotive door handle can be used for unlocking, thus achieving the effect of unlocking.

[0007] A door light module is provided on the top of the base. The door light module is used to monitor the locked state of the lock tongue, and a door light wiring is provided on the door light module for transmitting a door light signal.

[0013] Preferably, the base connects the actuator through a planar connecting member. A bolt post is provided on the front side of the base. A vertical plate is vertically provided on the left side of the bottom of the base. One end of the planar connecting member is connected to the bolt post through an upper mounting hole. The other end of the planar connecting member is connected to the vertical plate through a side mounting hole. The rotation plane of the swing arm is parallel to the rotation plane of the transmission member. A planar conversion arm is hinged on the base. The planar conversion arm is located on the back side of the transmission member. A rotation hole is provided on the planar conversion arm and the rotation hole is coaxial with the shaft hole. A clamping groove is provided on the planar conversion arm. The clamping groove cooperates with the clamping block. A dial groove is provided at the end of the planar conversion arm.

[0016] By installing a door light module on the top of the base, the present utility model facilitates the combination of a cam and a microswitch, converts the mechanical movement of the lock tongue into an electrical signal, and achieves the effect of controlling the door light signal. By installing an actuator at the bottom of the base using a connecting piece, using a swing arm to perform a control action, and using a conversion arm assembly to drive an unlocking conversion block, the linkage state between the unlocking assembly and the lock tongue is changed, achieving the effect of controlling whether the vehicle door lock can be unlocked through a door control signal. By using a separately installed door light module and actuator to replace the original actuator assembly, compared with the original structural solution, the occupation of the upper space is reduced, it can be applied to the inside of a vehicle door with a smaller installation space, the actuator can be installed in a parallel or vertical manner, and it can adapt to different installation environments, making the use of space more reasonable.
