Description

Technical Field

[0001] The invention 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 shell, 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 a car mechanical door lock, such as outside opening, inside opening and anti-locking.

[0003] When closing the door of an existing car, you need to forcefully drive the car door lock, which not only damages the car, but also makes the collision noise uncomfortable. Many people do not want to see the door of their car being smashed, so the researchers designed an electric suction mechanism that uses a motor to control the lock tongue to automatically switch from a half-locked state to a fully locked state, thereby realizing the self-suction function. However, the existing electric suction door lock usually has two or more motors for power output, which has higher requirements for the installation of the car door, increases the weight of the car door, and is inconvenient to install and operate.

[0004] A central control actuator is usually used in car door locks to control the unlocking / locking of the inner and outer 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 occupies 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. Summary of the invention

[0039] like Figure 5 and Fig.13 As 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 seat 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 rod 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.

[0040] like Figure 5 and Fig.13 As shown, the lock block 13 is installed in the front cavity 1021 of the main shell through the second pin shaft 1301, and 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 seat 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.

Each suction sensor 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, and 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, and the self-suction drive motor 23 is started. The self-suction transmission member 232 drives the screw rod 22 to rotate, so that the slide 21 moves along the screw rod 22, pushes the lock tongue swing arm 121 to rotate, and converts the semi-locked state of the lock tongue block 12 to the fully locked state, thereby realizing the automatic suction of the door; and when unlocking, the slide 21 moves along the screw rod 22, pushes the lock hook arm 132, separates the pressing swing arm 131 of the lock hook block 13 from the lock tongue block 12, and the lock tongue block 12 is restored to the initial state under the action of the first reset spring 1201, and the vehicle body lock hook 100 is pushed out from the lock tongue groove 123 to realize electric unlocking. The self-suction sensor 51 is a Hall sensor, and the lock tongue swing arm 121 and the slide 21 are both provided with a magnet 52 that cooperates with the Hall sensor. When the lock tongue swing arm 121 and the slide 21 are in the corresponding position with the self-suction sensor, the magnet 52 acts on the Hall element inside the Hall sensor to generate 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.

[0042] like Fig.10 As shown, the self-priming transmission assembly 24 includes a first gear 241 matched with the worm 231 on the self-priming drive motor 23, a second gear shaft seat 242 coaxially rotating with the first gear 241, a third gear 243 meshing with the second gear shaft seat 242, a fourth gear shaft seat 244 meshing with the third gear 243, and a sleeve seat 245 rotating synchronously with the fourth gear shaft seat 244, the sleeve seat 245 is sleeved on the end of the screw 22, 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, and 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, and the third gear 243 drives the fourth gear shaft seat 244 to rotate, and the sleeve seat 245 drives the screw rod 22 to rotate synchronously with the fourth gear shaft seat 244, so that the slide seat 21 can move linearly up and down along the screw rod 22.

[0043] like Figure 5As shown, the top portion of the lock housing 10 is provided with a placement groove 14 for placing the self-suction drive motor 23 and the self-suction transmission assembly 24, the screw 22 is in the main housing placement cavity 1023, the self-suction drive motor 23 and the self-suction transmission assembly 24 are placed in the placement groove 14 in an L shape, the self-suction 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 control of the door lock is improved. The placement groove 14 is also equipped with a cover plate 141 to protect the self-suction drive motor 23 and the self-suction transmission assembly 24 in the placement groove 14.

[0044] A self-priming placement seat 15 is also provided in the lock shell 10, and the self-priming placement seat 15 includes a first placement seat 151, a second placement seat 152 and a placement sleeve 153 which are 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, and 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, thereby 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 convex seat 211 and a side convex ridge 212, the magnet 52 is arranged in the convex seat 211, the convex seat 211 cooperates with the slide groove 1532, and the side convex ridge 212 cooperates with the guide groove.

[0045] The specific working process of the self-closing driving mechanism 20 is as follows: (1) When the vehicle door is not closed forcefully, the vehicle body lock hook 100 is inserted into the lock slot 11 of the vehicle 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 vehicle door is not closed forcefully, 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, as shown in FIG. Figure 7As shown; (2) the magnet 52 on the bolt 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-suction drive motor 23 is started, and the screw rod 22 is driven to rotate forward through the self-suction transmission component 24, so that the slide 21 moves along the screw rod 22 toward the self-suction transmission component 24, pushing the bolt swing arm 121 to move upward, driving the bolt block 12 to rotate, thereby driving the door to close in the direction close to the vehicle body, realizing the automatic suction of the door, as shown in FIG. Figure 8 As shown; (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, and the magnet 52 on the lock tongue swing arm 121 acts on the Hall element inside the bottom of the full lock sensor 5102 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, and the self-attraction 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 to prevent the lock tongue block 12 from rotating arbitrarily to unlock. When the lock tongue block 12 is in the full lock state, the pressing swing arm 131 is stuck. (4) When the main control module 50 receives the electric unlocking signal, the self-suction driving motor 23 is started, and the screw rod 22 is driven to rotate in the opposite direction through the self-suction transmission component 24, and the slide 21 moves along the screw rod 22 away from the self-suction 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 from the lock tongue groove 123 to achieve electric unlocking. Fig. 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-closing drive motor 23 drives the screw 22 to rotate forward through the self-closing transmission component 24, and the slide 21 moves along the screw 22 toward the self-closing 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-closing 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 in FIG. Figure 6 shown.
