[0040] In actual application of this embodiment, during the actual use of the door lock control device, the V-shaped groove 103 on one side of the front cover plate 102 is used to buckle the lock ring on the vehicle body. When the lock ring is pressed on the locking piece 303 at one end of the lock tongue body 301, since the lock tongue body 301 is rotatably assembled on the front fixing frame 108, the lock tongue body 301 can be pushed to rotate in a clockwise direction in the xz plane. When the lock tongue body 301 is not in the fully locked position, the induction magnet 307 arranged at the bottom of the swing arm 305 is inductively sensed by the Hall element arranged inside the lock housing 101, thereby detecting that the lock tongue body 301 is in the fully locked position. 01 is in a semi-locked state, and the suction motor 207 arranged inside the lock housing 101 engages and drives the suction bevel gear 206 to rotate. Since the suction bevel gear 206 is rotatably sleeved on the ring 202 and fixedly connected with the suction gear 203, the suction gear 203 drives the screw 204 to make a linear motion in the first direction x during the process of engaging with the screw 204. At this time, the screw column 205 at one end of the screw 204 is pressed on the swing arm 305, and the swing arm 305 moves toward the side away from the locking buckle 401.

[0047] In actual application of this embodiment, the inner unlocking pull rod 801 and the inner unlocking transmission plate 803 are arranged in layers in the third direction z, so that when the inner unlocking pull rod 801 rotates clockwise, there is no linkage function between the inner unlocking head 802 at one end thereof and the inner unlocking transmission plate 803, and when the child lock plate 807 is in the unlocked state, the child lock rod 808 at one end of the child lock plate 807 is inserted into the U-shaped groove 805, so that the inner unlocking head 802 at one end of the inner unlocking pull rod 801 is locked. During the rotation process, it can abut against the child lock rod 808, and the child lock rod 808 drives the inner unlocking transmission plate 803 to rotate in the xz plane, so that the transmission plate pressure plate 804 at one end of the inner unlocking transmission plate 803 can be movably abutted against the unlocking plate 502, so that the unlocking plate 502 drives the locking buckle 401 to rotate in the xy plane, so that the stopper 402 is loosened from one side of the locking member 303, thereby realizing the inner cable unlocking function. At the same time, the child lock function can also be realized by raising and lowering the child lock plate 807.

[0048] See also Figure 5 , Figure 7 , Figure 8 and Fig. 9In a preferred embodiment of the utility model, the central control assembly 9 includes a central control unlocking piece 901, a fan tooth plate 902, a limit bracket 903, a central control limit arm 904, a ball rod 905, a central control transmission piece 906, a ball groove 907, a key unlocking arm 908, a side rod 909, a central control motor 910 and a central control transmission gear 911. The central control unlocking piece 901 is rotatably arranged in the xy plane, and the central control unlocking piece 901 is provided with a fan tooth plate 902 at one end, and the central control limit arm 904 and the ball rod 905 are provided at the other end of the central control unlocking piece 901. The limit bracket 903 is fixedly arranged on the lock housing 1 01, it is used to limit the rotation trajectory of the central control unlocking piece 901, the central control limiting arm 904 is arranged close to one side of the limiting ear plate 806, the central control transmission piece 906 is rotatably arranged on the rear fixed frame 109, and a ball groove 907 is arranged at one end of the central control transmission piece 906, the ball groove 907 is rotatably assembled in the ball rod 905, and a key unlocking arm 908 is arranged at the other end of the central control transmission piece 906, the side rod 909 is fixedly arranged on one side of the central control transmission piece 906, the central control motor 910 is assembled in the lock housing 101 and is meshed with the fan tooth plate 902 through the central control transmission gear 911.

[0049] When this embodiment is actually used, the central control motor 910 at one end of the central control unlocking piece 901 can drive the central control transmission gear 911 to rotate in the xy plane under the driving state, so that the fan tooth plate 902 meshing with the central control transmission gear 911 drives the central control unlocking piece 901 to rotate in a directional manner. Since the ball rod 905 and the ball groove 907 are rotationally connected, the ball rod 905 on one side of the central control unlocking piece 901 can drive the central control transmission piece 906 to rotate in the xz plane during the rotation process, and when the central control limiting arm 904 at one end of the central control unlocking piece 901 rotates toward one end of the inner unlocking rod 801, the central control limiting arm 904 can abut against the limiting ear plate 806 at one end of the inner unlocking rod 801 to limit the rotation of the inner unlocking rod 801, thereby realizing the central control locking function, and at the same time, it can also link the central control connecting rod assembly 7 for locking.

[0050] In one case of the present embodiment, the integrated automobile door lock control device also includes an emergency locking component 10, which is assembled in the lock shell 101 and is buckled with the side rod 909. When the power supply of the central control system is abnormal, the key can be inserted into the emergency locking component 10 and the key can be rotated to drive the emergency locking component 10 to rotate. The side rod 909 connected to the emergency locking component 10 can drive the central control transmission plate 906 to rotate in the xz plane, so that the central control connecting rod 701, one end of which is movably assembled on the central control transmission plate 906, moves synchronously, so that the connecting rod head 702 is loosened from the movable slot 503, so that the contact surface between the crimping joint 703 and the locking buckle 401 disappears, and the outer unlocking rod 6 cannot realize the unlocking function during the rotation process. At the same time, the central control limit arm 904 abuts against the limit ear plate 806 at one end of the inner unlocking rod 801, so that both the inner and outer unlocking are invalid, so as to realize the emergency locking of the vehicle door.
