[0037] Reference Figure 1-Figure 7 According to an embodiment of a highly integrated vehicle door lock of the utility model, a highly integrated vehicle door lock includes a base 11, a safety gear 12 is rotatably connected to the base 11, the safety gear 12 includes a rotating wheel 30, and a half gear ring 21, a tension plate 22, a trigger plate 23 and a clamping plate 24 are integrally formed on the outer curved surface of the rotating wheel 30.

[0038] The base 11 is fixed with a motor 31, and the output shaft of the motor 31 is connected to a worm 32 meshing with the half gear ring 21, that is, when the motor 31 is powered on, the worm 32 can be driven to rotate the safety gear 12;

[0039] An inner opening arm 41 is rotatably connected to the base 11, and the inner opening arm 41 is pressed on the tension plate 22. An inner handle cable (not shown in the figure) is connected to the inner opening arm 41. When the user pulls the inner handle in the car, the inner opening arm 41 can be pulled by the inner handle cable, thereby driving the tension plate 22 and the safety gear 12 to rotate.

[0040] A locking wheel 51 is rotatably connected inside the base 11 , and the safety gear 12 can drive the locking wheel 51 to rotate through an unlocking mechanism, thereby unlocking the locking pin.

[0041] In addition, a signal switch No. 1 13 that can be triggered by the trigger plate 23 is also provided in the base 11. When the safety gear 12 rotates to drive the lock wheel 51 to rotate and unlock, the trigger plate 23 triggers the signal switch No. 1 13, thereby transmitting a signal that the door is opened.

[0042] In this embodiment, the unlocking mechanism includes a No. 1 opening linkage plate 61 rotatably connected to the base 11, an extension plate 62 clamped in the clamping plate 24 is installed on the side of the No. 1 opening linkage plate 61, and a fan-shaped plate 63 is integrally formed on the side of the No. 1 opening linkage plate 61, and a safety transition rod 64 is slidably connected in the fan-shaped plate 63;

[0043] A second opening linkage plate 65 is rotatably connected in the base 11, the other end of the safety transition rod 64 is overlapped in the second opening linkage plate 65, and the second opening linkage plate 65 is attached to the push plate 42 extending from the inner opening arm 41;

[0044] A control wheel 71 is rotatably connected inside the base 11, and the safety transition rod 64 can be adapted to the control wheel 71, and the control wheel 71 is adapted to the locking wheel 51, that is, under certain conditions, the No. 2 opening linkage plate 65 can drive the control wheel 71 to rotate through the safety transition rod 64 when rotating, thereby allowing the locking wheel 51 to be unlocked.

[0045] In this embodiment, when manual unlocking is required, the user needs to pull the inner handle cable twice:

[0046] Before the wire is pulled, the safety transition rod 64 is close to the second opening linkage plate 65, so that the safety transition rod 64 is misaligned with the control wheel 71;

[0047] When the inner handle cable is pulled for the first time, the inner opening arm 41 is used to drive the tension plate 22 and the safety gear 12 to rotate. When the safety gear 12 rotates, the extension plate 62 and the fan plate 63 are driven to rotate through the clamping plate 24. During this process, the safety transition rod 64 maintains contact with the fan plate 63 and moves toward the direction of the No. 1 opening linkage plate 61. When the fan plate 63 rotates to the right position, the fan plate 63 is no longer misaligned with the control wheel 71.

[0048] Thereafter, when the inner handle cable is pulled for the second time, the inner opening arm 41 can drive the second opening linkage plate 65 to rotate, and then drive the control wheel 71 to rotate through the safety transition rod 64, so that the locking wheel 51 is unlocked.

[0049] It should be noted that during the first pulling of the inside handle cable, the motor 31 will drive the worm 32 to rotate to prevent the safety gear 12 from getting stuck, and after the first pulling of the inside handle cable, the angle of the safety gear 12 will be locked by the worm 32, so that the control wheel 71 can be driven to rotate when the inside handle cable is pulled for the second time.

[0050] Furthermore, in order to facilitate resetting, a safety torsion spring 66 is installed in the first opening linkage plate 61, and the other end of the safety torsion spring 66 is inserted into the safety transition rod 64;

[0051] The base 11 is also provided with an eccentric spring 67, the other end of which is fixed in the first opening linkage plate 61;

[0052] The base 11 is provided with an opening linkage plate torsion spring 68, and the other end of the opening linkage plate torsion spring 68 is connected to the inner opening arm 41;

[0053] The base 11 is provided with a control wheel torsion spring and a locking wheel torsion spring, and the ends of the control wheel torsion spring and the locking wheel torsion spring are connected to the control wheel 71 and the locking wheel 51 respectively.

[0054] In addition, the control wheel 71 includes a wheel body and a hook plate 72 . The hook plate 72 extends out of the wheel body and extends upward so that the hook plate 72 can contact the safety transition rod 64 .

[0055] The safety transition rod 64 includes a main body plate 81, one end of the main body plate 81 is bent downward and then extended laterally to form a No. 1 slide plate 82, and the No. 1 slide plate 82 is attached to the upper side surface of the fan-shaped plate 63, the other end of the main body plate 81 is bent downward and then extended front and back to form a No. 2 slide plate 83, and the No. 2 slide plate 83 can be attached to the upper side surface of the No. 2 opening linkage plate 65, and the lower sides of the No. 1 slide plate 82 and the No. 2 slide plate 83 are each provided with an end 84 to prevent the safety transition rod 64 from being separated from the No. 2 opening linkage plate 65 and the fan-shaped plate 63.

[0056] A fixing bead 91 is provided at the end of the extension plate 62, and the width of the clamping groove 92 in the clamping plate 24 is not less than the diameter of the fixing bead 91, that is, the fixing bead 91 is inserted into the clamping groove 92 to reduce the wear when the clamping plate 24 drives the extension plate 62 to rotate.

[0057] In addition, a second signal switch for sensing the real-time status of the locking wheel 51 is also provided in the base.

[0058] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
