[0035] transmission rod 1, U-shaped mounting seat 2, locking arm 3, rotating rod 4, motor 5, worm 6, outer opening output arm 7, pawl 8 and clutch block 9;
[0036] The U-shaped mounting seat 2 is installed on one side of the surface of the transmission rod 1;
[0037] The rotating rod 4 is arranged inside the U-shaped mounting seat 2;
[0038] The locking arm 3 is connected to one end of the rotating rod 4;
[0039] The worm 6 is engaged on one side of the locking arm 3;
[0040] The motor 5 is connected to one end of the worm 6;

[0042] The pawl 8 is connected to the bottom of the outer opening output arm 7;
[0043] The clutch block 9 is arranged on the surface of the outward opening output arm 7.
[0044] A transmission arc 10 is arranged on one side of the surface of the transmission rod 1.
[0045] A transmission cylinder 11 is arranged in the transmission arc 10.
[0046] A second rotating part 12 is arranged between the transmission rod 1 and the outward opening output arm 7.
[0047] A mounting through hole 13 is arranged on the surface of the locking arm 3, and a first rotating part 14 is arranged in the mounting through hole 13.
[0048] The transmission arc 10 is matched with the transmission cylinder 11, so as to provide accurate movement track guidance for the transmission process and avoid component movement interference.
[0049] The transmission cylinder 11 is a key component for power transmission, and realizes flexible transmission cooperation between the transmission rod 1 and related components.
[0050] The second rotating part 12 provides a stable rotating center for the outward opening output arm 7, so as to guarantee the smoothness and accuracy of the rotating action of the outward opening output arm 7.
[0051] The first rotating part 14 provides support for the rotating action of the locking arm 3, and ensures that the locking arm 3 stably rotates around the fixed axis.
[0052] The working principle of the novel automobile door lock electric unlocking function structure is as follows:
[0053] When the electric unlocking function needs to be realized, the motor 5 is started and outputs power, drives the connected worm 6 to rotate, the worm 6 drives the locking arm 3 to rotate around the first rotating part 14 through meshing transmission, when the locking arm 3 rotates, the rotating rod 4 connected to one end of the locking arm 3 synchronously swings in the U-shaped mounting seat 2, the swinging of the rotating rod 4 drives the transmission rod 1 to move through transmission correlation, the transmission arc 10 on the surface of the transmission rod 1 cooperates with the transmission cylinder 11, so as to ensure that the transmission rod 1 moves stably along the preset track.
[0054] The movement of the transmission rod 1 is transmitted to the outward opening output arm 7 through the second rotating part 12, drives the outward opening output arm 7 to rotate around the second rotating part 12, the pawl 8 at the bottom of the outward opening output arm 7 rotates synchronously, the pawl 8 is disengaged from the locking structure in the door lock, and at the same time, the clutch block 9 on the surface of the outward opening output arm 7 completes the clutch state switching, so as to realize the electric unlocking of the door lock.
[0055] When the electric locking function needs to be realized, the motor 5 is started in reverse, the locking arm 3 is driven to rotate in reverse through the worm 6, the outer opening output arm 7 is driven to rotate in reverse through the rotating rod 4 and the transmission rod 1 in turn, the pawl 8 reengages with the door lock locking structure, the clutch block 9 resets, and the electric locking of the door lock is completed.
[0056] During the whole unlocking process, the first rotating part 14 and the second rotating part 12 provide stable rotating support for the locking arm 3 and the outer opening output arm 7 respectively, the cooperation of the transmission arc 10 and the transmission cylinder 11 guarantees the accuracy and smoothness of power transmission, and the cooperative work of the components ensures that the unlocking action is responsive and stable.

[0062] The bolt 153 is arranged between the mounting block 152 and the transmission rod 1.
[0063] In the process of electric unlocking of the door lock, the mounting assembly 15 provides stable support and fixation for the U-shaped mounting base 2, the two positioning blocks 151 effectively limit the lateral deviation of the U-shaped mounting base 2 during movement, and the locking effect of the bolt 153 ensures that the mounting block 152 and the transmission rod 1 are not relatively loose, thereby ensuring the movement stability of the rotating rod 4, the locking arm 3 and other components, and further ensuring the power transmission accuracy of the entire transmission chain, so that the unlocking action is not affected by the installation connection part, and smooth and stable movement is maintained.
