[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] First embodiment

[0025] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic structural diagram of a first embodiment of an M4 side door lock assembly provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the three-dimensional structure of the entire internal structure of the device shown; Figure 3 for Figure 1 A schematic diagram of the overall structure of a part of the device is shown. An M4 side door lock assembly includes:

[0026] A base 1 is provided with a rotating rod 2 on the surface of the base 1, a movable arm 4 is provided on the surface of the rotating rod 2, a rotating member 3 is provided on the surface of the rotating rod 2 and below the movable arm 4, a rotating block 10 is provided on the surface of the rotating rod 2 and below the rotating member 3, one side of the surface of the rotating block 10 is connected to an L-shaped limit block 11, and one side of the rotating member 3 is connected to a limit block 12.

[0027] A rotating seat 8 is disposed on one side of the base 1 , and a movable stopper 5 is connected to one side of the movable arm 4 .

[0028] A rotating block 6 is disposed on one side of the rotating seat 8 , and a mounting fixing plate 9 is connected to one side of the surface of the base 1 .

[0029] A movable block 7 is sleeved on the surface of the rotating block 6 .

[0030] A fixing plate 14 is disposed on one side of the base 1 .

[0031] The original integrated pawl riveted structure is optimized to a pawl flat plate stamping structure, opening arm and pawl assembly structure, the transmission system is relatively simple, the production process is more stable, the reliability is higher, and the product performance is superior.

[0032] When the car door lock pulls the outside handle or the inside handle, the pawl rotates through the transmission system, and the ratchet is released to open the door; when the door is in the locked state and the door is closed, the ratchet rotation drives the opening arm to release the door, thereby achieving the function of preventing accidental locking.

[0033] Compared with the related art, the M4 side door lock assembly provided by the utility model has the following beneficial effects:
