[0002] An automobile is a vehicle that has its own power to drive, does not need to rely on tracks or power lines, and can travel motorized. Generally speaking, vehicles driven by their own mechanical energy are commonly called automobiles. With the development of society, automobiles are becoming more and more popular.

[0003] At present, most of the common automobile side doors are traditional door locks that are manually closed. During the process of closing the door, if the force is too large, the air pressure inside the vehicle will cause discomfort to the human ear; if the force is too small, the door may not close tightly. The existing door locks have a semi-locked and fully locked state when closing. In order to achieve the automatic transition of the door from semi-locked to fully locked, a large number of components such as complex switch controls, sensor mechanisms, and cable drive parts are generally required, which will affect the assembly speed of the door and increase the occupied space at the same time.

The motor box mechanism includes a motor assembly, a gear assembly, a cable wheel 20 and a reset magnet 21. The motor assembly is connected to the cable wheel 20 through the gear assembly. The cable wheel 20 is used to connect to the cable 24, and the reset magnet 21 is arranged on the cable wheel 20. The motor assembly includes a motor body 8, an upper cover 1, a base 17, a driving PCB board 19, a first retaining piece 9, a second retaining piece 3, a speed PCB board 11, a worm 7, a speed detection magnetic ring 6, a motor copper bushing 4, a motor shock absorber 5 and a sealing ring 2. The motor body 8, the driving PCB board 19, the first retaining piece 9, the second retaining piece 3, the speed PCB board 11, the worm 7, the speed detection magnetic ring 6, the motor copper bushing 4 and the motor shock absorber 5 are all arranged inside the base 17. The upper cover 1 movably covers the base 17, and the sealing ring 2 is located between the upper cover 1 and the base 17. The gear assembly includes a first gear 14, a second gear 16, a third gear 13, a first rotating shaft 23, a second rotating shaft 15 and a third rotating shaft 12. The first rotating shaft 23, the second rotating shaft 15 and the third rotating shaft 12 are all arranged on the base 17. The cable wheel 20 and the first gear 14 are both rotationally arranged on the first rotating shaft 23. The second gear 16 is rotationally arranged on the second rotating shaft 15. The third gear 13 is rotationally arranged on the third rotating shaft 12. The second gear 16 is rotationally connected to the worm 7. The second gear 16 meshes with the third gear 13, and the third gear 13 meshes with the first gear 14. That is to say, the driving PCB board 19 is installed in the square groove on the base 17. The speed PCB board 11 is installed at the corresponding position on the base 17. The first retaining piece 9 is placed in the rear slot on the base 17. The second retaining piece 3 is placed in the front slot in the base 17. The motor body 8 is pressed into the worm 7, and the speed detection magnetic ring 6 is pressed into the front end of the worm 7. And a motor shock absorber 5 is sleeved on each end of the motor body 8. Then, the positive and negative wire harnesses are welded into a component and welded to the positive and negative solder joints on the driving PCB board 19.

[0028] Further, the first gear 14 is a 54-tooth gear, the second gear 16 is a 53-tooth helical gear, and the third gear 13 is a 43-tooth rotating gear 13. A first magnet fixing seat 33 is provided on the stretching piece body 34, and a first magnet 35 is detachably provided on the first magnet fixing seat 33.

[0029] During use, a signal magnet fixing seat 36 is provided on the outer door cable connecting piece of the original vehicle, and the signal magnet 40 is placed in the signal magnet fixing seat 36. Then, a fixing frame 37 is provided at the position on the original vehicle's housing closest to the signal magnet fixing seat 36, and a signal PCB board 38 is placed in the fixing frame 37. That is to say, through this handle signal mechanism, during the closing and sucking process of the electric suction lock, when the handle is pulled up, the signal magnet 40 on the cable connecting piece moves away from the signal PCB board 38, causing the signal to change from "0" to "1", which can interrupt the entire sucking action. Then, the motor body 8 is reversed to release the cable 24 to open the lock tongue and open the door, thereby protecting the user's personal or property safety in an emergency. That is to say, the signal PCB board 38 is a signal Hall PCB board, and there is a fourth HALL Hall sensor 44 on this signal Hall PCB board. That is, in the initial state of the handle, the signal magnet 40 on the signal magnet fixing seat 36 senses the fourth HALL Hall sensor 44, and the signal is "0" at this time. During the sucking process, when the original vehicle lock body handle needs to be pulled to open the door urgently, the signal magnet fixing seat 36 installed on the outer door cable connecting piece of the original vehicle drives the cable connecting piece away from the fourth HALL Hall sensor 44 when pulling the handle until it is out of the sensing range, and the signal becomes "1" at this time. That is to say, during the closing and sucking process, once this signal changes to the high level "1", the control board MCU will give an instruction to interrupt the sucking, reverse the motor, release the cable 24 to open the lock tongue, so as to achieve the purpose of being able to open the door at any time during the sucking process.

[0030] In the above embodiments, there are a first HALL Hall sensor 41, a second HALL Hall sensor 42, and a third HALL Hall sensor 43 on the lock body PCB board 45. That is to say, the three Hall sensors are used to be sensed by the first magnet 35 on the stretching piece body 34. Among them, the first HALL and the second HALL are connected in series to form the same HALL signal. That is to say, by setting the first magnet 35, when the lock tongue assembly rotates to the half-lock state and drives the stretching piece body 34 to the half-lock state at the same time, the first magnet 35 reaches within the sensing range of the first HALL Hall sensor 41, and the signal changes from "1" to "0". At this time, the third HALL Hall sensor is still not in the sensing area with the first magnet 35, and the signal remains "1". At this time, the half-lock signal is 0-1, and the motor box mechanism starts to drive the motor body 8 to achieve the suction function. When the lock tongue assembly is in the open state, the first magnet 35 on the stretching piece body 34 stops at a position far away from the first HALL, the second HALL, and the third HALL where it cannot be sensed. At this time, the first HALL Hall sensor 41, the second HALL Hall sensor 42, and the third HALL Hall sensor 43 on the lock body PCB board 45 are all at high level. And because the first HALL and the second HALL are connected in series to form the same HALL signal, that is, when the lock tongue is opened, the signal is 1-1. The MCU receives the signal and issues an instruction to judge that the motor will not work at this time. During the process of suction to the full-lock state, because the first HALL and the second HALL are within the sensing range of the first magnet 35, they are both at low level "0". Because the third HALL is still in the off state and is at high level "1", until the third HALL is inductively sensed, the signal becomes low level. The motor body 8 stops after rotating forward for the set time according to the signal change and then reverses back to the initial state. At this time, it is in the fully locked state.

[0031] In the above embodiments, when the user closes the door with too much force, it is equivalent to directly closing the door to the tight state with acceleration at this time. Because the residence time of the first magnet 35 at the first HALL and the second HALL is too short, the signal at this time is also 0-0. Based on this information, the motor body 8 does not operate, so it can well prevent misjudgment. Further, the first HALL, the second HALL Hall sensor 42, and the first magnet 35 are in the sensed state, and the signals are all at low level "0". The third HALL is in the sensed state, and the signal is low level 0. Based on the signal 0-0, it is judged that the door is fully closed. After waiting for the set time, it will enter the sleep state, and the power consumption will be very low; if the door is opened, it will trigger the detection of the fourth HALL signal on the signal PCB board 38, and the lock tongue will pop open. The first magnet 35 on the stretching piece body 34 will return to the initial position, leaving the third HALL, the second HALL, and the first HALL. At this time, the signal is 1-1. Based on this information, it is awakened and enters the working mode; to achieve the purpose of electrically sucking and closing the door lock.

[0032] In summary, the above embodiments are not restrictive embodiments of the present utility model. Any modification or equivalent deformation made by those skilled in the art based on the substantial content of the present utility model falls within the technical scope of the present utility model.
