Description

Technical Field

[0001] This utility model belongs to the field of automotive door lock technology, and in particular relates to an emergency double-pull unlocking mechanism for automotive electric door locks. Background Technology

[0002] The emergency unlocking mechanism of existing car door locks usually allows the lock to be unlocked by pulling the cable once when the door is locked. This can easily lead to occupants accidentally opening the car door due to the accidental activation of the emergency unlocking mechanism, which has an adverse impact on the safety of the driver and passengers. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides an emergency double-pull unlocking mechanism for automotive electric door locks. When locked, an external force pulls the emergency cable once to unlock the lock body. After release, pulling the emergency cable again drives the lock body's opening mechanism to open the door lock. This effectively reduces the probability of occupants accidentally opening the car door due to mis-triggered emergency opening mechanism, improves the safety of drivers and passengers, and enhances customer satisfaction.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an emergency double-pull unlocking mechanism for an electric car door lock, including a housing, a lock body opening mechanism, and at least the following:

[0005] An emergency opening linkage is rotatably connected to the housing and is equipped with a lever, a limiting groove, and a third push block;

[0006] The rotating arm is rotatably connected to the housing and has a first push block that can cooperate with the lock body opening mechanism for opening the door lock;

[0007] The clutch lever is equipped with a lever, which is rotatably connected to the opening rotating arm, and the two have a first state in which the lever abuts against the opening rotating arm and a second state in which the lever disengages from the opening rotating arm.

[0008] The central control linkage has a second push block;

[0009] A double-pull rotating arm is rotatably connected to the housing and is provided with a second stop arm that can abut against the lever;

[0010] The transmission rods are rotatably connected to the double-pull rotating arm and the central control linkage, respectively.

[0011] The emergency opening linkage moves in the first direction, and the lever pushes the double-pull rotating arm to rotate, thereby driving the transmission rod to push the central control linkage to move in the second direction. The lever and the opening rotating arm can switch from the second state to the first state.

[0012] Furthermore, when the electric door lock is locked, the toggle block and the opening rotating arm are in a second state, and the toggle block is located in the limiting groove;

[0013] An external force is applied to pull the emergency opening linkage in the first direction. The lever pushes the double-pull rotating arm to rotate, thereby driving the transmission rod to push the central control linkage to move to the unlocked state in the second direction. The second push block disengages from the lever block.

[0014] The emergency opening linkage is reset, the toggle block disengages from the limiting groove, and the toggle block and the opening rotating arm switch from the second state to the first state;

[0015] When an external force is applied and the emergency opening linkage is pulled again, the push block pushes the toggle block to drive the opening rotating arm to rotate, and the first push block pushes the lock body opening mechanism to open the door lock.

[0016] Furthermore, the second direction is horizontal, and the first direction is vertical.

[0017] Furthermore, it also includes a locking swing arm, which is connected to the central control linkage. Under electric drive, the locking swing arm rotates to drive the central control linkage to move in the second direction to the unlocked state or the locked state. When an external force is first applied to pull the emergency opening linkage in the first direction, the central control linkage moves in the second direction and pushes the locking swing arm to switch from the locked state to the unlocked state simultaneously. The central control linkage moves to the right to the unlocked state and to the left to the locked state.

[0018] Furthermore, the emergency opening linkage, the opening rotating arm, and the double-pull rotating arm are rotatably connected to the housing via the first rotating shaft.

[0019] Furthermore, the opening rotating arm is equipped with an electric opening stop arm, which can cooperate with the electric opening mechanism. Under the action of the electric opening mechanism, the opening rotating arm can rotate circumferentially to push the lock body opening mechanism to open the door lock.

[0020] Furthermore, the emergency opening linkage is connected to an emergency opening cable.

[0021] Furthermore, the lever is vertically positioned on the surface of the emergency opening linkage; the emergency opening linkage is provided with an emergency pull cable mounting hole, which is located close to the lever.

[0022] Furthermore, the second stop arm is provided with a stop made of elastic material.

[0023] Furthermore, the double-pull rotating arm is provided with a first connecting hole and a first mounting hole for passing through the first rotating shaft, and the second stop arm and the first mounting hole are located on both sides of the first connecting hole.

[0024] Furthermore, both the opening rotating arm and the emergency opening linkage are equipped with a rotational reset component.

[0025] The beneficial effects of this utility model are: 1) The emergency double-pull unlocking mechanism achieves emergency door lock opening by pulling the emergency opening linkage twice, effectively reducing the risk of passengers accidentally opening the car door due to accidental triggering; 2) The emergency double-pull unlocking mechanism can satisfy the normal electric locking, unlocking, and opening of the door lock, and can also realize manual double-pull mechanical opening of the door lock in an emergency. The functions do not interfere with each other, which is ingeniously designed; 3) The toggle block and the opening rotating arm have a first state and a second state. When the car's electric door lock is locked, it is in the second state. When the emergency opening cable is pulled for the first time, the central control linkage moves to the right to unlock first. The opening rotating arm will not push the lock body opening mechanism to open the door lock. At the same time, the second push block disengages from the toggle block. Only when the emergency opening cable is pulled a second time will the push block push the lever, which in turn drives the opening rotating arm to rotate, allowing the lock body opening mechanism to open the door lock. The structural linkage is simple and effective. 4) The emergency opening linkage has a lever, a limit groove, and a third push block. The limit groove isolates the lever and the first stop arm of the opening rotating arm. The third push block pushes the lever. The structural design is reasonable, and pulling the emergency opening cable twice can achieve different results. 5) The cooperation structure of the emergency opening linkage, double-pull rotating arm, transmission rod, and central control linkage is ingenious. The up and down movement of the emergency opening linkage realizes the rotation of the double-pull rotating arm and transmission rod, and then realizes the translation of the central control linkage. 6) The overall structural design is reasonable and will not increase the volume of the car door lock.

Detailed Implementation

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0037] An emergency double-pull unlocking mechanism for an electric car door lock includes a housing 1, an emergency opening linkage 2, an opening rotating arm 3, a clutch lever 4, a double-pull rotating arm 5, a transmission rod 6, a central control linkage 7, a locking swing arm 8, and a lock body opening mechanism 9. The emergency opening linkage 2, the opening rotating arm 3, and the double-pull rotating arm 5 are sequentially connected to the housing 1 via a first rotating shaft 10, and can each rotate around the first rotating shaft 10.

[0038] like Figure 6 As shown, the emergency opening linkage 2 has a lever 202 vertically disposed on its surface, a limiting groove 204, a third push block 203 located on one side of the opening of the limiting groove 204, an emergency pull cable mounting hole 201 disposed near the lever 202, and a rotation reset component. In this embodiment, the rotation reset component is a torsion spring, which drives the emergency opening linkage 2 to move in the opposite direction to reset after it moves upward. The emergency pull cable mounting hole 201 is connected to an emergency opening pull cable 13.

[0039] like Figure 7As shown, the opening rotating arm 3 is equipped with a first push block 301, an electric opening stop arm 302, a first stop arm 303, and a rotation reset component. The opening rotating arm 3 can cooperate with the lock body opening mechanism 9. Specifically, the first push block 301 cooperates with the lock body opening mechanism 9 to open the door lock. The electric opening stop arm 302 cooperates with the electric opening mechanism 01. The electric opening mechanism 01 can drive the opening rotating arm 3 to rotate clockwise, causing the first push block 301 of the opening rotating arm 3 to push the lock body opening mechanism 9 to unlock the door lock. After the electric opening mechanism 01 completes the unlocking action, it reverses to reset and releases the opening rotating arm 3. Under the action of its own rotation reset mechanism, the opening rotating arm 3 reverses to reset and releases the lock body opening mechanism 9.

[0040] In this embodiment, the rotation reset component is a torsion spring, which drives the rotating arm 3 to rotate in the opposite direction to reset after the rotating arm 3 is opened. Of course, in other embodiments, other structures in the prior art can also be selected, and no specific limitation is imposed.

[0041] The clutch lever 4 is vertically mounted with a lever 401, and the clutch lever 4 is rotatably connected to the opening rotating arm 3. Both have a first state and a second state. In the first state, the lever 401 abuts against the first stop arm 303 of the opening rotating arm 3. In the second state, the lever 401 disengages from the first stop arm 303. Under normal circumstances, the lever 401 and the first stop arm 303 are in the first state of contact; only under the action of an external force will they switch from the first state to the second state.

[0042] like Figure 8 As shown, the double-pull rotary arm 5 is provided with a second stop arm 503, which can abut against the lever 202. In order to reduce the noise when the two abut against each other, a stop block 504 made of elastic material can be sleeved on the second stop arm 503. The double-pull rotary arm 5 is also provided with a first connecting hole 502 and a first mounting hole 501 for passing through the first rotating shaft 10. The second stop arm 503 and the first mounting hole 501 are located on both sides of the first connecting hole 502. The first connecting hole 502 is used to rotatably connect the transmission rod 6.

[0043] like Figure 9As shown, a second push block 701 is vertically arranged at one end of the central control linkage 7, and a U-shaped opening groove 703 is vertically arranged at the other end. A second mounting hole 702 is also vertically arranged on the surface of the central control linkage 7. The two ends of the transmission rod 6 are rotatably connected to the double-pull rotating arm 5 and the second mounting hole 702 of the central control linkage 7, respectively. The U-shaped opening slot 703 is connected to the locking swing arm 8. Specifically, the U-shaped opening slot 703 is connected to the lever 81 vertically arranged on one side of the plane of the locking swing arm 8. Under electric drive, the locking swing arm 8 can drive the central control linkage 7 to move to the unlocked state or the locked state in the second direction by rotating clockwise or counterclockwise. Specifically, the central control linkage 7 moves to the right to the unlocked state and moves to the left to the locked state. Conversely, in the locked state, the emergency opening linkage 2 is pulled up for the first time by the emergency opening pull cable 13. The emergency opening linkage lever 202 pushes the double pull rotating arm 5 to rotate clockwise and pushes the central control linkage 7 to move to the right through the transmission rod 6. It also pushes the locking swing arm 8 to rotate clockwise together to switch from the locked state to the unlocked state.

[0044] It should be noted that without electric drive, external force pulling the emergency release lever 2 can only drive the central control lever 7 to move to the right to the unlocked state, but cannot drive the central control lever 7 to move to the left to the locked state.

[0045] like Figure 1 As shown, when the electrically operated door lock is in the locked state, under the action of the second push block 701 of the central control linkage 7, the toggle block 401 and the opening rotating arm 3 are in a second state of disengagement, and the toggle block 401 is located in the limiting groove 204. At this time, since the toggle block 401 and the first stop arm 303 do not abut against each other, that is, both are in the second state, the first push block 301 will not push the lock body opening mechanism 9 to open the door lock.

[0046] When the emergency release linkage 2 moves in the first direction, in this embodiment, it is... Figure 2 Taking the indicated direction as an example, the first direction is vertical (although the emergency opening linkage 2 rotates circumferentially, this is illustrated using the direction of movement of the emergency opening cable 13 as an example, where part of the emergency opening linkage 2 moves vertically). Specifically, an external force is applied through the emergency opening cable 13 to pull the emergency opening linkage 2 upwards. The lever 202 abuts against the stop 504 of the double-pull rotating arm 5 and pushes the double-pull rotating arm 5 to rotate clockwise. The double-pull rotating arm 5 drives the transmission rod 6 to rotate and pushes the central control linkage 7 to move in the second direction. In this embodiment, taking... Figure 2 Taking the direction shown as an example, the first direction is left and right horizontally. Specifically, the central control linkage 7 moves to the right and pushes the locking arm 8 to rotate clockwise to the unlocked state. The second push block 701 of the central control linkage 7 disengages from the contact with the clutch lever 4 toggle block 401.

[0047] like Figure 3As shown, after the emergency opening cable 13 pulls up the emergency opening linkage 2 once, it releases the emergency opening linkage 2. Under the action of its own rotational reset component, the emergency opening linkage 2 rotates and resets. The lever 401 of the clutch lever 4 disengages from the limiting groove 204 of the emergency opening linkage 2 and, under the action of its own rotational reset component, abuts against the first stop arm 303 of the opening rotating arm 3. That is, the lever 401 and the first stop arm 303 switch from the second state to the first state. At this time, the second stop arm 503 remains at the high position.

[0048] like Figure 4 As shown, when an external force is applied to pull the emergency opening linkage 2 for the second time, the push block 203 pushes the clutch lever 4's shift block 401 and drives the opening rotating arm 3 to rotate clockwise. The first push block 301 of the opening rotating arm 3 pushes the lock body opening mechanism 9 to open the door lock.

[0049] like Figure 5 As shown, after the emergency opening cable 13 pulls up the emergency opening linkage 2 for the second time, the emergency opening linkage 2 is released. The emergency opening linkage 2 is rotated and reset under the action of its own rotation reset component. The opening rotating arm 3 is also reversed and reset together with the clutch lever 4 under the action of its own rotation reset component.

[0050] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
