Description

Technical Field

[0001] This utility model relates to the field of automotive door lock technology, specifically to an automotive door lock locking device. Background Technology

[0002] A car door lock is a device installed on the door and its pillar to reliably lock the door and achieve opening and closing functions through its internal mechanism. The locking device, also known as the latch, is the core component of the car door lock system. It is a control device that provides locking / unlocking pulse current to the door lock actuator. Regardless of the type of door lock actuator, it controls the left and right movement of the linkage by changing the direction of the energized current in the actuator to achieve locking and unlocking of the door. The widespread use of this device makes it an indispensable part of modern automotive safety systems.

[0003] However, in some car doors, during the closing process, the lock cylinder converts electrical energy into mechanical energy through current. Before locking, the lock cylinder and bolt cannot quickly connect and engage, causing the locking device to be unable to open or close the locking mechanism when power is lost, which poses a certain safety hazard. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-3As shown, this utility model provides a car door lock locking device, including a housing 1. A locking mechanism 3 is movably installed inside the housing 1. A hook 2 is fixedly installed at one end of the housing 1. The locking mechanism 3 includes two first gears 31, one end of which is rotatably connected to the inner wall of one end of the housing 1. Two torsion springs 32 are sleeved on one end of each first gear 31. Each end of the first gear 31 has a meshing groove 34. A retaining plate 33 is fixedly connected to one end of each first gear 31. A pin 35 is inserted and connected to one end of the housing 1. One end of the pin 35 is fixedly connected to a locking plate 38, and the other end of the pin 35 is fixedly connected to a transmission handle 36. A spring 37 is fixedly sleeved on the outer surface of the pin 35. One end of the spring 37 is fixedly connected to one end of the locking plate 38. The operator can rotate the car door, and the locking mechanism 3 at one end of the car door will quickly contact the hook 2, causing the two first gears 31 to rotate synchronously through the hook 2 and the two locking plates 33, thereby engaging the two first gears 31 with the hook 2 through the two meshing grooves 34, thus realizing the quick locking of the car door.

[0016] One end of the transmission handle 36 is fixedly connected to a connecting shaft 11. A second gear 12 is fixedly mounted on one end of the connecting shaft 11. A rack 13 is meshed with the outer surface of the second gear 12. One end of the rack 13 is fixedly connected to a first connecting rod 15. One end of the first connecting rod 15 is rotatably connected to a transmission plate 16. One end of the transmission plate 16 is rotatably connected to a second connecting rod 17. One end of the second connecting rod 17 is inserted into a handle frame 18. A release handle 19 is rotatably connected to the inner wall of one end of the handle frame 18. One end of the second connecting rod 17 is fixedly connected to the end of the release handle 19, and can be released by pulling. The handle 19 causes the release handle 19 to rotate axially. The rotating release handle 19 drives the first connecting rod 15 to move in the opposite direction through the transmission of the second connecting rod 17 and the transmission plate 16. As a result, the rack 13 moves and applies a rotational force to the second gear 12. The rotating second gear 12 drives the transmission handle 36 to tilt and rotate to a certain extent, thereby disengaging the locking plate 38 at one end of the transmission handle 36 from the two clamping plates 33. Finally, under the reaction force of the two torsion springs 32, the first gear 31 is rotated and reset, realizing the quick opening of the car door and improving the convenience of opening and closing the car door.

[0017] The two first gears 31 and the two meshing grooves 34 are mirror-distributed. The outer surfaces of the two locking plates 33 slide against the outer surface of the locking plate 38, and the two locking plates 33 are set at an inclined angle. One end of the hook 2 is U-shaped and fixedly connected to the door frame. One end of the housing 1 has a slot that mates with one end of the hook 2. The housing 1 and the locking mechanism 3 are located inside one end of the door. One end of each of the two torsion springs 32 engages with the tooth grooves of the two first gears 31, and the other end of each torsion spring 32 is fixedly connected to the outer surface of the two first gears 31. The two mirror-distributed first gears 31 can move in a relatively synchronous manner when contacting the hook 2. The rotational motion provides the same torque to the two torsion springs 32. When the two locking plates 33 rotate to a certain extent, they slide against the outer surface of the locking plate 38. Under the action of rotation, the two sliding locking plates 33 engage with the two ends of the locking plate 38 at an inclined angle, helping the two first gears 31 to achieve limit locking. The "U"-shaped end provides a meshing space for the two first gears 31, thus facilitating the meshing and locking process when the door contacts the door frame. The engagement of one end of the two torsion springs 32 with the tooth groove of the first gear 31 causes the two torsion springs 32 to be compressed during the rotation of the two first gears 31, providing energy storage for the reverse rotation of the two first gears 31.

[0018] The transmission plate 16 is set at an inclined angle. When the second connecting rod 17 moves, the inclined transmission plate 16 drives the first connecting rod 15 to move in the opposite direction, thereby providing a fixed distance of movement for the rotation of the second gear 12.

[0019] Working principle: When the operator closes the car door, the car door drives the outer shell 1 and the internal locking mechanism 3 to rotate and approach the hook 2. The hook 2 located on the door frame pushes the two inclined plates 33 in the locking mechanism 3 to one side, causing the two first gears 31 to rotate synchronously. During the rotation, the two first gears 31 engage with the hook 2 through the two meshing grooves 34. At this time, the two first gears 31 lock the hook 2. At the same time, the locking plate 38 continuously brushes against the tooth grooves of the two first gears 31 through the extension and contraction of the spring 37. When the two first gears 31 rotate to a certain extent, the two rotating plates 33 lock the two sides of the locking plate 38 through synchronous rotation, thereby completing the locking action of the two first gears 31 and locking the door.

[0020] When the car door needs to be opened, the operator pulls one end of the release handle 19, which causes the second link 17 to move horizontally. The moving second link 17 rotates through the inclined transmission plate 16. The rotating transmission plate 16 causes the first link 15 to move horizontally in the opposite direction, which causes the rack 13 to move linearly on the outer surface of the second gear 12. This causes the second gear 12, which is engaged at the bottom, to rotate. The rotating second gear 12 drives the transmission handle 36 to rotate through the connecting shaft 11. The rotating transmission handle 36 drives the locking plate 38 to rotate, causing the locking plate 38 to tilt continuously. This causes the two locking plates 33 to disengage from the locking plate 38, which causes the two first gears 31 to rotate through the reaction torque of the two torsion springs 32. This causes the two engagement grooves 34 to disengage from the hook 2 during rotation, thus opening the locking mechanism 3.

[0021] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
