[0024] The present invention will be further described below.

[0025] See attached document Figure 1-4 An electric child safety mechanism is installed inside the housing of a car door lock, including a support plate 3 and a conductive plate secondary plastic coating sub-assembly. The support plate 3 and the conductive plate secondary plastic coating sub-assembly are assembled on the lock body. The conductive plate secondary plastic coating sub-assembly includes a conductive plate secondary plastic coating 5. A wire 45 and a micro switch 23 are welded to the conductive plate secondary plastic coating 5. The micro switch includes a micro switch door light signal 23-3, a micro switch locking signal 23-2, and a micro switch child safety signal 23-1.

[0026] The support plate 3 is provided with a pediatric worm gear center column 46, an inward-opening center column 47, and a pediatric rocker arm center column 48. The support plate 3 is provided with a pediatric motor 9, the positive and negative poles of which are connected to the secondary plastic-coated sub-assembly. A pediatric worm gear 8 is provided on the motor shaft of the pediatric motor 9. An electric pediatric worm gear 7 is provided on the pediatric worm gear center column 46. The electric pediatric worm gear 7 is rotatably mounted on the support plate 3 and meshes with the pediatric worm gear 8 for transmission. An electric pediatric rocker arm 14 is provided on the pediatric rocker arm center column 48. One end of the electric pediatric connecting rod 6 is driven by the electric pediatric worm gear 7, and the other end is driven by the electric pediatric rocker arm 14. An inward-opening return spring 10, a rear inward-opening rocker arm 11, and a pediatric driven arm 13 are provided on the inward-opening center column 47. One end of the electric pediatric knob 44 is connected to the pediatric driven arm 13, and the other end is connected to the electric pediatric rocker arm 14.

[0027] The electric child safety connecting rod 6 has protruding cylinders at both ends, the electric child safety worm gear 7 has a U-shaped groove, and the electric child safety rocker arm 14 has a U-shaped slot. The protruding cylinder at one end of the electric child safety connecting rod 6 is driven in the U-shaped groove, and the protruding cylinder at the other end is driven in the U-shaped slot.

[0028] The electric child care knob 44 has a groove at one end and a protrusion at the other end. The electric child care rocker arm 14 has a shaped structure, and the child care driven arm 13 has a slot. The groove at one end of the electric child care knob 44 is driven at the corresponding position of the shaped structure of the electric child care rocker arm 14, and the protrusion at the other end is located in the slot of the child care driven arm 13.

[0029] The support plate 3 is provided with a guide groove. When the child protection device is locked or unlocked, the child protection motor 9 rotates, which drives the child protection worm gear 8 to rotate. The child protection worm gear 8 drives the electric child protection worm wheel 7 to rotate. The electric child protection worm wheel 7 drives the electric child protection connecting rod 6 to slide along the guide groove and push the electric child protection rocker arm 14. The electric child protection rocker arm 14 drives the electric child protection knob 44 to realize the unlocking and locking of the child protection function.

[0030] The micro switch 23 is disposed on the secondary plastic coating 5 of the conductive plate. The micro switch child safety signal 23-1 is welded to the secondary plastic coating 5 of the conductive plate through the wire 45. The micro switch child safety signal 23-1 cooperates with the electric child safety worm gear 7. The lower end of the electric child safety worm gear 7 is provided with a pressing feature surface facing the micro switch child safety signal 23-1. When the electric child safety worm gear 7 rotates and moves in different directions, the pressing feature surface contacts or moves away from the micro switch child safety signal 23-1, which can provide a signal to the vehicle body control system to lock or unlock the child safety system.

[0031] When the door lock receives a signal, the child safety motor 9 rotates, which drives the child safety worm gear 8 to rotate. The child safety worm gear 8 drives the electric child safety worm wheel 7 to rotate. The electric child safety worm wheel 7 drives the electric child safety connecting rod 6. The electric child safety connecting rod 6 drives the electric child safety rocker arm 14. The electric child safety rocker arm 14 drives the electric child safety knob 44 to move simultaneously, realizing the unlocking and locking of the child safety function.

[0032] like Figure 5 As shown, when the child safety lock is engaged, the rear inward-opening rocker arm 11 cannot rotate to push the electric child safety knob 44, and the child safety driven arm 13 is disconnected from the inward-opening transmission mechanism; as Figure 6 As shown, when the child safety lock is unlocked, the rear inner opening rocker arm 11 rotates to push the electric child safety lock knob 44, and the child safety lock driven arm 13 contacts the inner opening transmission mechanism, thus opening the inner opening.

[0033] In specific implementation, the electric child safety monitoring function of this utility model is realized as follows: When the lock body receives the child safety monitoring locking signal from the vehicle control system through the data connector, it sends an energizing signal to the child safety monitoring motor 9 through the secondary plastic coating 5 of the conductive plate. The rotation of the child safety monitoring motor 9 drives the child safety monitoring worm gear 8 to rotate. The child safety monitoring worm gear 8 drives the electric child safety monitoring worm wheel 7 to the position 7-1 when the electric child safety monitoring worm wheel is locked. The electric child safety monitoring worm wheel 7 drives the electric child safety monitoring connecting rod 6 to the position 6-1 when the electric child safety monitoring connecting rod is locked. The electric child safety monitoring connecting rod 6 drives the electric child safety monitoring rocker arm 14 to the position 14-1 when the electric child safety monitoring rocker arm is locked. The electric child safety monitoring rocker arm 14 drives the electric child safety monitoring knob 44 to the position 44-1 when the electric child safety monitoring knob is locked. When the child safety monitoring worm gear 8 drives the electric child safety monitoring worm wheel 7 to the correct position, the contact on the electric child safety monitoring worm wheel 7 will contact the micro switch 23. The micro switch child safety monitoring signal 23-1 sends a child safety monitoring lock signal to the vehicle control system, realizing the locking function of the electric child safety monitoring function.

[0034] Similarly, when the lock body receives the child safety unlock signal from the vehicle control system via the data connector, it sends an energizing signal to the child safety motor 9 through the conductive plate 5. The child safety motor 9 rotates, causing the child safety worm gear 8 to rotate. The child safety worm gear 8 then rotates the electric child safety worm wheel 7 to the unlocking position 7-2. The electric child safety worm wheel 7 then rotates the electric child safety connecting rod 6 to the unlocking position 6-2. The electric child safety connecting rod 6 then rotates the electric child safety rocker arm 14 to the unlocking position 14-2. The electric child safety rocker arm 14 then rotates the electric child safety knob 44 to the unlocking position 44-2. When the child safety worm gear 8 rotates the electric worm wheel 7 to its final position, the contacts on the electric child safety worm wheel 7 will disengage from the child safety signal 23-1 of the micro switch. The micro switch 23 then sends a child safety unlock signal to the vehicle control system, thus unlocking the electric child safety function.

[0035] The above embodiments of this utility model are merely examples to clearly illustrate this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent technical solutions also fall within the scope of this utility model, and the patent protection scope of this utility model should be defined by each claim.
