Embodiment 1

[0026] An external locking module of a motor vehicle door lock, comprising a knob 1 , a transmission arm 2 , a lower case 4 and an upper case 5 . Wherein the upper case 4 and the lower case 5 are interlocked to form a lock case as a supporting member, and the knob 1 and the transmission arm 2 are movably installed on the lock case. The knob 1 is used as a driving part of the transmission arm 2, and its outer end has a socket 1.1, and its inner end is connected to a column 1.4 via a section of torsion arm. The transmission arm 2 is used as a follower for rotation 1 and also as a driver for locking and unlocking the lock body. Its inner end has a long slot 2.1, and its outer end has a drive slot 2.3 for driving the lock body to lock and unlock. The connection structure between the knob 1 and the transmission arm 2 is: the column 1.4 of the knob 1 is inserted into the long slot 2.1 of the transmission arm 2, and during the rotation of the knob 1, the column 1.4 is inserted into t...

Abstract

The invention relates to an external locking module of a motor vehicle door lock, which comprises a knob and a transmission arm which are arranged between an upper shell and a lower shell, and is characterized in that the knob is used as a torsion driving piece for external opening and is rotationally supported between the upper shell and the lower shell, the outer end of the knob is provided witha torsion opening insertion hole, and the inner end of the knob is linked with the transmission arm through a stand column; the transmission arm serves as a driven part of the knob and is slidably installed between the upper shell and the lower shell, the inner end of the transmission arm is provided with a long groove inserted into the stand column, and the outer end of the transmission arm is used for driving the lock body to be locked and unlocked. By turning on the outer end of the knob, the stand column at the inner end of the knob slides in the long groove of the transmission arm, and meanwhile the rotary motion of the knob is converted into the linear motion of the transmission arm. The module is fewer in parts, simpler in structure, easier to manufacture and more suitable for a small structural space of the lock.

Description

technical field [0001] The invention relates to the technical field of automobile door locks, in particular to an external locking module of a motor vehicle door lock. Background technique [0002] The locking module usually uses an externally opened knob to drive the transmission arm to realize the locking and unlocking of the lock body. Under the limited structural space, it is necessary to convert the rotary motion of the knob into the linear motion of the transmission arm. The traditional locking module is connected between the knob and the transmission arm through a conversion part, and the direction of movement is switched while transmitting the torque. However, this structure has many structural parts and takes up a lot of space. During the mating process, the transmission stability and reliability are not good. Contents of the invention [0003] The present invention aims to solve the above-mentioned problems of many parts, complex structure, large space occup...
