Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an integrated vehicle door lock. Background Art

[0002] The composition of a car door lock contains multiple components, including the lock cylinder, lock tongue, outside handle, inside handle, lock rod, lock housing, electromagnet, large support body, control part, inside opening handle, outside opening handle, inside locking mechanism, pull rod, latch and lock catch. These components together realize the basic functions of the car mechanical door lock, such as outside opening, inside opening and anti-locking.

[0003] Existing car door locks require a firm force to close, which not only damages the car but also creates an uncomfortable noise. Many people also don't want to see their car doors slammed shut. Therefore, researchers have designed an electric locking mechanism that uses a single motor to automatically switch the lock tongue from a partially locked to a fully locked position, achieving a self-locking function. However, existing electric locking door locks typically utilize two or more motors for power output, which increases the installation requirements, significantly increases the weight of the door, and makes installation and operation inconvenient.

[0004] Car door locks usually use a central control actuator to control the unlocking / locking of the interior and exterior door handles. Due to the small space inside the car door, the self-priming actuator and the central control actuator cannot be installed in the car door lock at the same time. Instead, the self-priming actuator is placed externally and the self-priming actuator is outside the lock body. This takes up a large space inside the car door and increases the company's production and manufacturing costs. At the same time, multiple components need to be disassembled for inspection during the maintenance process, which reduces the efficiency of maintenance. Utility Model Content

The self-priming drive mechanism 20, the central control mechanism 40 and the unlocking transmission mechanism 30 are all integrated in the car door lock, which reduces the space occupied by the lock body, saves manufacturing costs, and is convenient for maintaining the door lock.

[0039] The main housing front cavity 1021 is provided with a main housing connecting plate 10211 for supporting and mounting the first pin 1201 and the second pin 1301, and a vehicle cover 10212 for covering the main housing front cavity 1021. The front side of the side housing 101 is equipped with a side cover 1011, and the main housing rear cavity 1022 and the rear side of the side housing cavity are equipped with a sealing cover 103.

[0040] like Figure 5 and Figure 13As shown, the lock tongue block 12 is installed in the front cavity 1021 of the main shell through the first pin shaft 1201. The lock tongue block 12 is provided with a lock tongue swing arm 121 and two lock tongue side arms 122 that cooperate with the slide 21. The two lock tongue side arms 122 form a lock tongue groove 123 that cooperates with the vehicle body lock hook 100. When the vehicle body lock hook 100 is inserted into the lock tongue groove 123, the lock tongue block 12 can be pushed to rotate to a semi-locked state. The screw 22 and the slider 21 can be used to push the lock tongue swing arm 121 to rotate, and the lock tongue block can be rotated to a fully locked state, thereby realizing automatic suction and locking of the vehicle door.

[0041] like Figure 5 and Figure 13 As shown, the lock block 13 is installed in the front cavity 1021 of the main shell through the second pin shaft 1301. The lock block 13 is provided with a lock pressing swing arm 131 for pressing on the lock tongue block 12, a lock hook arm 132 cooperating with the slide 21, and a lock unlocking swing arm 133 cooperating with the unlocking transmission mechanism 30. The lock pressing swing arm 131 is close to the lock tongue block 12, and the lock hook arm 132 and the lock unlocking swing arm 133 are respectively located above and below the lock block 13. Under the action of the second return spring 1302, the lock pressing swing arm 131 of the lock block 13 is always kept pressed on the lock tongue block 12 to prevent the lock tongue block 12 from rotating and unlocking at will; the screw 22 and the slider 21 can be used to push the lock hook arm 132 to move, so that the lock pressing swing arm 131 is separated from the lock tongue block 12, and the lock tongue block 12 can automatically rotate under the action of the first return spring 1202 to achieve unlocking. The lock tongue block 12 is further provided with a lock tongue protrusion 124 . The lock tongue protrusion 124 is located between the lock tongue swing arm 121 and the lock tongue side arm 122 . The lock pressing swing arm 131 of the lock buckle block 13 presses on the lock tongue protrusion 124 .

[0042] like Figures 6 to 9As shown, the self-sucking sensor 51 is divided into a half-lock sensor 5101, a full-lock sensor 5102, an unlocking sensor 5103 and a reset sensor 5104. Each of the suction sensors 51 is distributed above the screw 22. According to the position of the lock tongue swing arm 121 and the slide 21, a signal is sent to the main control module 50. The main control module 50 controls the start, forward rotation and reverse rotation of the suction drive motor 23. When the vehicle body lock hook 100 extends into the lock tongue groove 123, the lock tongue block 12 is in a half-locked state, the self-sucking drive motor 23 is started, and the lock tongue block 12 is in a half-locked state. The self-engaging transmission member 232 drives the screw 22 to rotate, causing the slide 21 to move along the screw 22, pushing the lock bolt swing arm 121 to rotate, converting the half-locked state of the lock bolt block 12 to the fully locked state, thereby realizing the automatic locking of the vehicle door; and when unlocking, the slide 21 moves along the screw 22, pushing the lock hook arm 132, separating the pressing swing arm 131 of the lock bolt block 13 from the lock bolt block 12, and the lock bolt block 12 returns to its initial state under the action of the first return spring 14, and the vehicle body lock hook 100 is pushed out of the lock bolt groove 123, realizing electric unlocking. The self-engaging sensor 51 is a Hall sensor, and the lock bolt swing arm 121 and the slide 21 are both provided with a magnet 52 that cooperates with the Hall sensor. When the lock bolt swing arm 121 and the slide 21 are in the corresponding position of the self-engaging sensor, the magnet 52 acts on the Hall element inside the Hall sensor, generating a Hall voltage, which is converted into an electrical signal by the signal processing circuit, thereby sending a signal to the main control module 50.

[0043] like Figure 10 As shown, the self-priming transmission assembly 24 includes a first gear 241 that cooperates with the worm 231 on the self-priming drive motor 23, a second gear shaft seat 242 that rotates coaxially with the first gear 241, a third gear 243 that meshes with the second gear shaft seat 242, a fourth gear shaft seat 244 that meshes with the third gear 243, and a sleeve seat 245 that rotates synchronously with the fourth gear shaft seat 244. The sleeve seat 245 is sleeved on the end of the screw 22, and the screw 22 rotates synchronously with the sleeve seat 245. The first gear 241 is sleeved on the second gear shaft seat 242, and the other end of the screw 22 The part is located in the placement hole in the main shell 102, so that when the worm 231 on the self-priming drive motor 23 rotates, it drives the first gear 241 to rotate, and the second gear shaft seat 242 rotates synchronously with the first gear 241. The third gear 243 is engaged with the second gear shaft seat 242, driving the third gear 243 to rotate, and the third gear 243 is engaged with the fourth gear shaft seat 244. The third gear 243 drives the fourth gear shaft seat 244 to rotate, and the sleeve seat 245 drives the screw 22 to rotate synchronously with the fourth gear shaft seat 244, so that the slide 21 can move straight up and down along the screw 22.

[0044] like Figure 5As shown, the top portion of the lock housing 10 is provided with a placement groove 14 for accommodating the self-priming drive motor 23 and the self-priming transmission assembly 24, the screw 22 is in the main housing placement cavity 1023, the self-priming drive motor 23 and the self-priming transmission assembly 24 are arranged in an L-shape in the placement groove 14, the self-priming transmission assembly 24 and the screw 22 are arranged in an L-shape, and the main control module 50 is arranged in the groove at the bottom end of the lock housing 10, so that the L-shaped space formed by the main housing 102 and the side housing 101 in the lock housing 10 is fully utilized, the occupied space is saved, the transmission is stable and reliable, the installation is simple and convenient, the door lock cost is reduced, and the intelligent door lock control is improved. The placement groove 14 is also equipped with a cover plate 141 to protect the self-priming drive motor 23 and the self-priming transmission assembly 24 in the placement groove 14.

[0045] The lock shell 10 is also provided with a self-priming placement seat 15, which includes a first placement seat 151, a second placement seat 152 and a placement sleeve 153 connected in sequence. The placement sleeve 153 is arranged in the main shell 102, and a screw groove 1531 for placing the screw 22 is provided in the placement sleeve 153. The screw groove 1531 is connected to a slide groove 1532 for sliding the slide seat 21. The first placement groove 1511 is arranged in the first placement seat 151, and the second placement groove 1521 is arranged in the second placement seat 152. The first placement seat 151 and the second placement seat 152 are L-shaped, and the second placement seat 152 and the placement sleeve 153 are L-shaped. In this way, the placement seat 15 is arranged in the lock shell 10, and the self-priming drive mechanism 20 is isolated from other structures in the lock shell 10, ensuring the smooth operation of the self-priming drive mechanism 20. The screw groove 1531 is also connected to a guide groove for guiding the slide; the slide 21 is provided with a boss 211 and a side ridge 212, the magnet 52 is arranged in the boss 211, the boss 211 cooperates with the slide groove 1532, and the side ridge 212 cooperates with the guide groove.

[0046] The specific working process of the self-closing drive mechanism 20 is as follows: (1) When the car door is not closed with force, the car body lock hook 100 is inserted into the lock slot 11 of the car door lock, and the door body lock hook 100 is placed in the lock tongue slot 123 to push the lock tongue side arm 122, so that the lock tongue block 12 rotates. Since the car door is not closed with force, the lock tongue block 12 can only rotate to a semi-locked state. At this time, the lock tongue swing arm 121 on the lock tongue block 12 is below the semi-locked sensor 5101. Figure 7As shown; (2) the magnet 52 on the lock tongue swing arm 121 acts on the Hall element inside the half-lock sensor 5101, generating a Hall voltage, which is converted into an electrical signal by the signal processing circuit and sent to the main control module 50, and the self-sucking drive motor 23 is started, and the screw 22 is driven to rotate in the positive direction through the self-sucking transmission component 24, so that the slide 21 moves along the screw 22 toward the self-sucking transmission component 24, pushing the lock tongue swing arm 121 to move upward, driving the lock tongue block 12 to rotate, thereby driving the car door to close in the direction close to the car body, realizing the automatic suction of the car door, as shown Figure 8 (3) until the lock tongue swing arm 121 rotates to the bottom of the full lock sensor 5102, the lock tongue block 12 is in the full lock state, the magnet 52 on the lock tongue swing arm 121 acts on the Hall element inside the bottom of the full lock sensor 5102, generates a Hall voltage, which is converted into an electrical signal by the signal processing circuit and sent to the main control module 50, and the self-absorbing drive motor 23 stops starting. At this time, under the action of the second reset spring 1302, the pressing swing arm 131 on the lock block 13 always presses on the lock tongue block 12 during the rotation of the lock tongue block 12, preventing the lock tongue block 12 from rotating and unlocking at will. When the lock tongue block 12 is in the full lock state, the pressing swing arm 131 is locked. (4) When the main control module 50 receives the electric unlocking signal, the self-priming drive motor 23 is started, and the screw 22 is driven to rotate in the opposite direction through the self-priming transmission component 24. The slide 21 moves along the screw 22 in the direction away from the self-priming transmission component 24, pushing the lock hook arm 132 to move downward until the slide 21 moves to the bottom of the unlocking sensor 5103. At this time, the pressing swing arm 131 of the lock block 13 is separated from the lock tongue groove 123 of the lock tongue block 12. The lock tongue block 12 is restored to its initial state under the action of the first return spring 1202, and the vehicle body lock hook 100 is pushed out of the lock tongue groove 123 to achieve electric unlocking. Figure 9 As shown; (5) When the slide 21 moves to the bottom of the unlocking sensor 5103, the magnet 52 on the slide 21 acts on the Hall element inside the unlocking sensor 5103 to generate a Hall voltage, which is converted into an electrical signal by the signal processing circuit and sent to the main control module 50. The self-priming drive motor 23 drives the screw 22 to rotate in the positive direction through the self-priming transmission component 24, and the slide 21 moves along the screw 22 toward the self-priming transmission component 24 until the slide 21 moves to the bottom of the reset sensor 5104. The magnet 52 on the slide 21 acts on the Hall element inside the reset sensor 5104 to generate a Hall voltage, which is converted into an electrical signal by the signal processing circuit and sent to the main control module 50. The self-priming drive motor 23 stops rotating. At this time, the lock block 13 rotates toward the lock tongue block 12 under the action of the second reset spring 1302, and the pressing swing arm 131 on the lock block 13 presses on the side wall of the lock tongue block 12, as shown Figure 6 shown.

The central control motor 41 is connected to the main control module 50, and the central control motor 41 drives the central control ratchet 43 to rotate through the central control gear set 42. The central control ratchet 43 controls the action of the unlocking transmission mechanism 30. The central control gear set 42 and central control ratchet 43 are mounted within the side housing 101 via a fourth pin 4201 and a fifth pin 4301, respectively. The central control ratchet 43 is provided with a sector gear portion 431 meshing with the central control gear set 42 and a drive ball rod 432 for driving the unlocking transmission mechanism 30. The central control motor 41 drives the central control worm 411 to rotate. The central control gear set 42 meshes with the sector gear portion 431, thereby driving the central control transmission ratchet 43 to rotate, thereby driving the drive ball rod 432 to rotate, thereby controlling the operation of the unlocking transmission mechanism 30.
