[0002] Car door locks typically have a safety feature that allows the door to be opened when the safety is released, but prevents the door from being opened from outside when the safety is engaged. With increasing safety requirements, car door locks are also required to have a super-lock function to prevent the door from being opened from inside the vehicle after being locked. This requires the addition of a super-lock structure, which complicates the design. Summary of the Invention

[0003] The embodiment of the present application provides a lock that realizes multiple functions such as releasing the safety, applying the safety, releasing the super lock and applying the super lock through a simple structure.

[0036] In the first state, the unlocking structure cooperates with the unlocking member, so that the opening structure can drive the unlocking member through the unlocking structure to unlock;

[0037] In the second state, the unlocking structure is separated from the unlocking member, so that the opening structure can drive the first slider to move along the first sliding groove through the unlocking structure, so that the second elastic member accumulates elastic potential energy acting on the stop portion, which is used to drive the second linkage member and the first linkage member to be relatively retracted, so that the linkage mechanism switches from the second state to the first state.

[0038] In one embodiment of the present application, the locking assembly abuts against one end of the second elastic member to limit the second elastic member from releasing elastic potential energy acting on the stop portion, thereby locking the linkage mechanism in the second state.

[0081] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0082] In the prior art, automobile door locks typically incorporate an electric worm gear mechanism, an electric release rocker arm, a locking linkage, and a stop lever. The forward and reverse rotation of the electric worm gear mechanism releases the safety. When the safety is released, the door can be opened; when the safety is engaged, the door cannot be opened from outside the vehicle. As safety requirements increase, automobile door locks are also required to implement a super-lock function to prevent the door from being opened from inside the vehicle after it is locked. This requires the addition of a super-lock structure, complicating the design.

[0083] In view of this, an embodiment of the present application provides a lock that can achieve safety, safety, and super lock unlocking through a driving mechanism, thereby increasing the function of the lock without adding additional structure.

[0084] The lock provided in the embodiment of the present application can be applied to a variety of equipment or structures, such as various types of door bodies. The embodiment of the present application does not limit this. For ease of understanding, the embodiment of the present application is described in detail with the lock installed on a car door.

[0085] According to the first aspect of this application, Figure 1 As shown, an embodiment of the present application provides a lock, which includes an unlocking member 2, a first opening component 31, a second opening component 32, a linkage mechanism 4, a locking component 5 and a driving mechanism 1.

[0086] The unlocking member 2 is a structure used to unlock the device. Taking the lock set on a car door as an example, the unlocking member 2 can be set inside the car door. When the unlocking member 2 is activated, it can drive the lock tongue 61 on the car door to move, thereby unlocking the car door. Therefore, when the unlocking member 2 is activated, the lock can be unlocked.

[0087] The first opening component 31 and the second opening component 32 are structures for driving the unlocking member 2 to move. The first opening component 31 and the second opening component 32 are configured to cooperate with or separate from the unlocking member 2. When the first opening component 31 and the second opening component 32 cooperate with the unlocking member 2, they can respectively drive the unlocking member 2 to unlock the lock. That is to say, when the first opening component 31 cooperates with the unlocking member 2, the first opening component 31 can be used to drive the unlocking member 2 to unlock the lock; when the second opening component 32 cooperates with the unlocking member 2, the second opening component 32 can be used to drive the unlocking member 2 to unlock the lock; when the first opening component 31 and the second opening component 32 cooperate with the unlocking member 2 at the same time, the lock can be unlocked by driving the unlocking member 2 by any one of the first opening component 31 and the second opening component 32. Figure 2 and Figure 3 As shown, the first opening component 31 and the second opening component 32 cooperate with the unlocking member 2. At this time, the lock is in the unlocked state, and the unlocking member 2 can be unlocked by driving the first opening component 31 or the second opening component 32. Figure 4 and Figure 5 As shown, the first opening component 31 and the second opening component 32 are separated from the unlocking member 2. At this time, the lock is in the secured state, and the unlocking member 2 cannot be unlocked by driving the first opening component 31 or the second opening component 32.

[0088] The linkage mechanism 4 is connected to the first opening assembly 31 and the second opening assembly 32. The linkage mechanism 4 is used to drive the first opening assembly 31 and the second opening assembly 32 to engage or disengage the unlocking member 2. The linkage mechanism 4 drives the first opening assembly 31 and the second opening assembly 32 to switch between the armed and disarmed states.

[0089] The locking assembly 5 is configured to unlock or lock the linkage mechanism 4. When the locking assembly 5 unlocks the linkage mechanism 4, the linkage mechanism 4 is in an active state, which can drive the first opening assembly 31 and the second opening assembly 32 to switch between the insurance state and the release state, and the lock is in the super lock state. Figure 6 and Figure 7 As shown, when the locking assembly 5 locks the linkage mechanism 4, the positions of the first opening assembly 31 and the second opening assembly 32 connected to the linkage mechanism 4 are locked, so that the first opening assembly 31 and the second opening assembly 32 remain separated from the unlocking member 2, and the lock is in the upper super lock state, thereby being locked in the upper insurance state, further ensuring that the first opening assembly 31 and the second opening assembly 32 cannot drive the unlocking member 2 to unlock.

[0090] The driving mechanism 1 can selectively drive the linkage mechanism 4 to drive the first opening component 31 and the second opening component 32 , or drive the locking component 5 to lock or unlock the linkage mechanism 4 .

[0091] The embodiment of the present application is provided with an unlocking member 2, a linkage mechanism 4, and a first opening component 31 and a second opening component 32 connected to the linkage mechanism 4, a locking component 5 and a driving mechanism 1, so that the driving mechanism 1 can selectively drive the linkage mechanism 4 or the locking component 5. When the driving mechanism 1 drives the linkage mechanism 4, the first opening component 31 and the second opening component 32 can be driven by the linkage mechanism 4 to cooperate with or separate from the unlocking member 2 to achieve safety and release. When the driving mechanism 1 drives the locking component 5, it can lock or unlock the linkage mechanism 4 to achieve super locking and release. Therefore, the technical solution provided by the embodiment of the present application can achieve multiple functions of safety, release, super locking and release of super locking through one driving mechanism 1, and the overall structure is simple.

[0092] In some embodiments, the linkage mechanism 4 includes a first state, a second state and a third state. In the first state, the linkage mechanism 4 enables the first opening component 31 and the second opening component 32 to cooperate with the unlocking member 2. In the second state, the linkage mechanism 4 separates the first opening component 31 and the second opening component 32 from the unlocking member 2. In the third state, the linkage mechanism 4 restricts the driving mechanism 1 from continuing to move in a set direction and has the potential energy to switch from the third state to the second state.

[0093] like Figure 2 and Figure 3 As shown, when the linkage mechanism 4 is in the first state, the lock is in the unlocked state which can be unlocked by the first opening component 31 and / or the second opening component 32; Figure 4 and Figure 5 As shown, when the linkage mechanism 4 is in the second state, the lock is in the secured state; during the process of switching the lock from the unlocked state to the secured state, the linkage mechanism 4 is configured to switch from the first state to the third state and then to the second state. When the linkage mechanism 4, under the action of the drive mechanism 1, switches from the first state to the third state, the linkage mechanism 4 exerts a restraining effect on the drive mechanism 1, restricting the drive mechanism 1 from continuing its current movement in the set direction. Because the linkage mechanism 4 has a third state that restricts the drive mechanism 1 from continuing to rotate, and because it can switch to the second state through its own potential energy in the third state, the drive mechanism 1 can be disengaged from the linkage mechanism 4 in the third state and the second state. Therefore, the drive mechanism 1 can be used to drive the locking assembly 5 after being secured, or to drive the unlocking and unlocking of the lock.

[0094] Further, please combine Figure 2-Figure 7 As shown, in some embodiments:

[0095] When the driving mechanism 1 moves the first stroke from the initial position, it drives the linkage mechanism 4 to switch from the first state to the third state. At this time, the linkage mechanism 4 can switch to the second state under the action of its own potential energy, so that the lock is switched from the unlocked state to the secured state.

[0096] When the driving mechanism 1 moves from the initial position to the second stroke, the locking assembly 5 is driven to lock the linkage mechanism 4 in the second state. At this time, the lock is super locked and locked in the safety state.

[0097] When the driving mechanism 1 moves the third stroke from the initial position, it drives the linkage mechanism 4 to switch from the second state to the first state, and drives the locking assembly 5 to unlock the linkage mechanism 4. At this time, the lock is switched from the super-locked and insurance-on state to the super-unlocked and insurance-unlocked state.

[0098] Therefore, the three motion modes of the driving mechanism 1 are combined with the three states of the linkage mechanism 4 to realize the functions of securing, super locking, and releasing the security and super locking.

[0099] Furthermore, the first stroke is the first distance the drive mechanism 1 moves from the initial position in the first direction, the second stroke is the second distance the drive mechanism 1 moves from the initial position in the first direction, and the third stroke is the second distance the drive mechanism 1 moves from the initial position in the second direction, wherein the first distance is less than the second distance, the first direction is opposite to the second direction, and the set direction is the first direction. In other words, the drive mechanism 1 moves the first stroke in the first direction to engage the safety, at which point the drive mechanism 1 can disengage the linkage mechanism 4 and return to its original position, and the drive mechanism 1 moves again in the first direction and a longer second stroke to engage the super lock; when the drive mechanism 1 moves from its original position in the second direction opposite to the first direction, the safety and super lock can be disengaged.

[0100] One of the first direction and the second direction may be a clockwise direction, and the other may be a counterclockwise direction.

[0101] In some embodiments, as Figure 8 As shown, the driving mechanism 1 includes a driving body 13 and a first driving member 131, a second driving member 132 and a third driving member 133 provided on the driving body 13. The driving body 13 can move from the initial position along the first direction and the second direction. The first driving member 131 drives the linkage mechanism 4 in the first stroke and the third stroke, the second driving member 132 drives the locking assembly 5 in the second stroke, and the third driving member 133 drives the locking assembly 5 in the third stroke. For example, the lock is in Figure 2 In the unlocked state shown in FIG, the linkage mechanism 4 is in the first state. At this time, the driving body 13 moves the first stroke clockwise in the first direction, and the first driving member 131 pushes the linkage mechanism 4 to move, so that the linkage mechanism 4 is in the second state and the lock is in Figure 4 The driving body 13 then moves counterclockwise in the second direction back to the initial position; when the driving body 13 moves clockwise in the first direction again and moves a longer second stroke, the second driving member 132 contacts the locking assembly 5 during this process and pushes the locking assembly 5 to lock the linkage mechanism 4, so that the lock is in the closed position. Figure 6 The upper super lock state shown in FIG, then the driving body 13 is returned to the initial position counterclockwise along the second direction. Figure 6In the upper super lock state shown, the driving body 13 moves counterclockwise from the initial position to the third stroke in the second direction, the third driving member 133 drives the locking assembly 5 to unlock, and the first driving member 131 drives the linkage mechanism 4 back to the first state, so that the lock is in the upper super lock state again. Figure 2 The insurance status shown is released.

[0102] In some embodiments, please refer to Figure 1 As shown, the driving body 13 includes a worm wheel, and the worm wheel includes an end face 13a and an outer peripheral surface 13b. The rotation axis of the worm wheel passes through the end face 13a. The first driving member 131, the second driving member 132 and the third driving member 133 are arranged on the end face 13a. The outer peripheral surface 13b surrounds the rotation axis of the worm wheel and is provided with gear teeth. The driving mechanism 1 also includes a rotary motor 12 and a worm 11. The worm is connected to the output end of the rotary motor 12 and meshes with the gear teeth of the worm wheel. By rotating the rotary motor 12 in the forward or reverse direction, the worm wheel is driven to rotate in the first direction or the second direction, thereby realizing multiple state switching of releasing the safety, applying the safety, releasing the super lock and applying the super lock.

[0103] In some embodiments, the drive mechanism 1 further includes a reset elastic member 14, one end of which is fixedly disposed and the other end is connected to the drive body 13. When the drive body 13 leaves the initial position, the reset elastic member 14 accumulates elastic potential energy used to drive the drive body 13 back to the initial position. By providing the reset elastic member 14, the motor does not need to be constantly powered on and can be powered on only when required, making the motor less prone to failure and fatigue. The reset elastic member 14 has a simple structure, a fast response speed, and does not require a complex electronic control system, resulting in a low failure rate and high reliability.

[0104] In some embodiments, as Figure 2-Figure 5 As shown, the linkage mechanism 4 includes a first linkage member 41, a second linkage member 42 and a first elastic member 44. The first linkage member 41 is connected to the first opening component 31, the second linkage member 42 is connected to the second opening component 32, and the second linkage member 42 is rotatably connected to the first linkage member 41 so that the first linkage member 41 and the second linkage member 42 can be relatively expanded or retracted. The first elastic member 44 is connected to at least one of the first linkage member 41 and the second linkage member 42. Figure 2 and Figure 3 As shown, the linkage mechanism 4 is in the first state, and the first linkage member 41 and the second linkage member 42 are relatively retracted in the first state; Figure 4 and Figure 5As shown, the linkage mechanism 4 is in the second state, with the first linkage member 41 and the second linkage member 42 relatively deployed in the second state. When the safety is engaged, the drive mechanism 1 drives the linkage mechanism 4 from the first state to the third state. During this process, the first elastic member 44 accumulates elastic potential energy. The first elastic member 44 releases the accumulated elastic potential energy in the third state, causing the linkage mechanism 4 to switch to the second state. By arranging the first linkage member 41, the second linkage member 42, and the first elastic member 44, the first linkage member 41 and the second linkage member 42 are relatively deployed or retracted, realizing the switching between the three states.

[0105] In some embodiments, as Figure 3-Figure 5 As shown, the linkage mechanism 4 further includes a first rotating shaft 43, and the second linkage member 42 is rotatably arranged about the first rotating shaft 43. The first linkage member 41 is connected to the driving mechanism 1, and the driving mechanism 1 drives the first linkage member 41 to move, thereby driving the second linkage member 42 to rotate about the first rotating shaft 43 and relative to the first linkage member 41, so that the first linkage member 41 and the second linkage member 42 are relatively deployed or retracted. By providing the first rotating shaft 43 to limit the degrees of freedom of the first linkage member 41 and the second linkage member 42, the movement of the first linkage member 41 can drive the second linkage member 42 to be deployed or retracted. Therefore, the state switching can be completed by only driving the first linkage member 41 or the second linkage member 42, simplifying the structure.

[0106] In some embodiments, as Figure 3-Figure 5 As shown, the first elastic member 44 has a first connecting end 441 and a second connecting end 442. The second connecting end 442 is fixedly arranged. The first connecting end 441 is connected to the second linkage member 42. The first connecting end 441 is configured to swing around the second connecting end 442 during the rotation of the second linkage member 42. The first connecting end 441 restricts the rotation of the second linkage member 42 in the first state and the second state, and deforms in the third state to accumulate elastic potential energy for switching the linkage mechanism 4 to the second state.

[0107] As an example, Figure 3 As shown, the first connection end 441 swings to one side of the second connection end 442 in the first state, as shown in FIG. Figure 5 As shown, the first connection end 441 swings to the other side of the second connection end 442 in the second state, wherein the first connection end 441 swings to a position closer to the second connection end 442 in the third state, so as to be in a state of greater deformation, thereby providing elastic force to the second linkage 42, pushing the second linkage 42 and driving the first linkage 41 so that the first linkage 41 and the second linkage 42 are further expanded, thereby switching to the second state.

[0108] In some embodiments, the first linkage member 41 includes a first force-bearing portion. In the first and third states, the first force-bearing portion is located along the movement path of the first driving member 131 during the first stroke. In the second state, the first force-bearing portion avoids the movement path of the first driving member 131 during the second stroke. By providing the first force-bearing portion on the first linkage member 41 and cooperating with the first driving member 131 in different ways depending on the state of the linkage mechanism 4, selective coordination between the driving mechanism 1 and the linkage mechanism 4 is achieved, thereby enabling a single driving mechanism 1 to perform functions other than arming and disarming the safety.

[0109] In some embodiments, the first force-bearing portion has a force-bearing surface and a blocking surface. The force-bearing surface abuts against the first driving member 131 in the first state to move the first linkage member 41 and drive the second linkage member 42 to rotate relative to the first linkage member 41 and expand to the third state; the blocking surface abuts against the first driving member 131 in the third state to limit the first driving member 131 from moving along the first direction.

[0110] As an example, the first driving member 131 includes a hook portion 1311, the first force-bearing portion includes a receiving slot, the receiving slot has an opening for the hook portion 1311 to enter, the force-bearing surface is the bottom wall of the receiving slot and is disposed opposite the opening, and the blocking surface is the side wall of the receiving slot. The relative movement of the first driving member 131 and the first linkage member 41 changes the mating relationship between the hook portion 1311 and the receiving slot, achieving power transmission and mutual restriction through a simple structure, enabling functional switching without adding additional structural components, and achieving both increased functionality and simplified structure.

[0111] In some embodiments, the first linkage member 41 further includes a second force-bearing portion, which is spaced apart from the first force-bearing portion so that, in the second state, the second force-bearing portion is located along the movement path of the first driving member 131 in the third stroke. By providing the second force-bearing portion on the first linkage member 41, the first driving member 131 of the drive mechanism 1 can again engage with the first linkage member 41 via the second force-bearing portion in the second state, thereby achieving the function of releasing the safety device through the drive mechanism 1.

[0112] In some embodiments, as Figure 2-Figure 5As shown, the linkage mechanism 4 further includes a second elastic member 45, the second linkage member 42 is provided with a stopper 422, a first slide groove 421 and a first slider 423, the first slider 423 is slidably arranged in the first slide groove 421, one end of the second elastic member 45 abuts the stopper 422, and the other end is connected to the first slider 423; the second opening component 32 includes an opening structure 321 and an unlocking structure 322, the unlocking structure 322 is movably arranged in the opening structure 321 and connected to the second linkage member 42. Figure 2 and Figure 3 As shown, in the first state, the unlocking structure 322 cooperates with the unlocking member 2, so that the opening structure 321 can drive the unlocking member 2 to unlock through the unlocking structure 322; Figure 4 and Figure 5 As shown, in the second state, the unlocking structure 322 is separated from the unlocking member 2, allowing the opening structure 321 to drive the first slider 423 along the first slot 421 via the unlocking structure 322. This allows the second elastic member 45, with its accumulated elastic potential energy acting on the stopper 422, to retract the second linkage member 42 and the first linkage member 41 relative to each other, thereby switching the linkage mechanism 4 from the second state to the first state. Through the coordination of the second elastic member 45, the stopper 422, the first slot 421, and the first slider 423, as well as the coordination of the opening structure 321 and the unlocking structure 322 of the second opening assembly 32, the lock can be switched from the secured state to the unsecured state when the lock is in the secured and super-locked state. This ensures the unlocking function of the lock even if the drive mechanism 1 fails or loses power. When the lock is used in a vehicle door, the second opening assembly 32 can be connected to the interior door handle to enable manual unlocking and disengaging of the lock from inside the vehicle, preventing occupants from being locked out and improving safety.

[0113] As an example, consider Figure 3 As shown, the opening structure 321 is provided with a second slide groove 3211, and the unlocking structure 322 is provided with a first block 3221 and a second block 3222. A portion of the first block 3221 extends into the second slide groove 3211 to slide with the second slide groove 3211, and another portion of the first block 3221 protrudes in a direction away from the plane where the second slide groove 3211 is located. The end of the second linkage member 42 away from the first rotating shaft 43 is located between the other portion of the first block 3221 and the second block 3222. In the released state, the linkage mechanism 4 is in the first state, and the first block 3221 is located at an end of the second slide groove 3211 close to the unlocking member 2 so that the other portion of the first block 3221 cooperates with the unlocking member 2, so that when the opening structure 321 rotates, the unlocking member 2 can be unlocked by the first block 3221. Figure 5As shown, when the linkage mechanism 4 switches to the second state, the second linkage member 42 shifts the second shift block 3222, so that the first shift block 3221 slides to the end of the second slide groove 3211 away from the unlocking member 2 to separate the other part of the first shift block 3221 from the unlocking member 2. At this time, the opening structure 321 rotates, and the first shift block 3221 of the unlocking structure 322 will rotate to the surface of the second linkage member 42 and push the first slider 423 to move along the first slide groove 421, so that the second elastic member 45 accumulates elastic potential energy.

[0114] In some embodiments, as Figure 6 and Figure 7 As shown, the locking assembly 5 abuts one end of the second elastic member 45, limiting the release of the elastic potential energy of the second elastic member 45 acting on the stop portion 422, thereby locking the linkage mechanism 4 in the second state. The cooperation between the locking assembly 5 and the second elastic member 45 realizes a super-locking function. When the lock is applied to a vehicle door, the super-locking function can be used to restrict occupants from disengaging or unlocking the door through the second opening assembly 32. This super-locking function can be used to ensure safety when the vehicle is in motion or when there are children or other individuals with limited mobility inside the vehicle.

[0115] In some embodiments, the locking assembly 5 includes a locked position and an unlocked position. Figure 2-5 As shown, the locking assembly 5 is located on the moving path of the second driving member 132 in the second stroke when in the unlocked position, as shown in FIG. Figure 6 and Figure 7 As shown, when the locking assembly 5 is in the locked position, it is located on the moving path of the third driving member 133 in the third stroke. Through the above arrangement, the selective cooperation between the driving mechanism 1 and the locking assembly 5 is achieved, thereby realizing the super locking, super unlocking and more functions through a single driving mechanism 1.

[0116] In some embodiments, please refer to Figure 1 As shown, the locking assembly 5 includes a locking member 51 and a third elastic member 52. The third elastic member 52 has a third connecting end 521 and a fourth connecting end 522. The fourth connecting end 522 is fixedly arranged. The third connecting end 521 is connected to the locking member 51. The locking member 51 and the third connecting end 521 are configured to swing around the fourth connecting end 522 between a locked position and an unlocked position. Figure 2-Figure 5 As shown, the locking member 51 and the third connecting end 521 are in the unlocking position to be away from the linkage mechanism 4. Figure 6 and Figure 7As shown, the locking member 51 and the third connecting end 521 are close to the linkage mechanism 4 in the locking position, and the third connecting end 521 provides elastic force to the locking member 51 so that the locking member 51 is held against the linkage mechanism 4, thereby locking the linkage mechanism 4 in the second state. As an example, Figure 4 and Figure 5 As shown, the locking member 51 and the third connecting end 521 are in the unlocked position away from one end of the second elastic member 45 of the linkage mechanism 4. At this time, one end of the second elastic member 45 can act on the second linkage member 42, so that the second linkage member 42 can be driven by the second elastic member 45 to rotate and drive the first linkage member 41 to move under the drive of the second opening component 32, thereby releasing the insurance; Figure 6 and Figure 7 As shown, the locking member 51 and the third connecting end 521 are close to the linkage mechanism 4 in the locking position, and the locking member 51 is abutted against one end of the second elastic member 45 under the action of the third connecting end 521, limiting the second elastic member 45 from applying force to the second linkage member 42, so that the second linkage member 42 cannot be driven by the second opening component 32, thereby locking the linkage mechanism 4 in the second state.

[0117] In some embodiments, please refer to Figure 1 As shown, the lock further includes a lock tongue 61, two pawls 62, two pawl elastic members 63, and a locking rod 64. The two pawls 62 are disposed on opposite sides of the lock tongue 61, and the two pawl elastic members 63 are disposed correspondingly to the two pawls 62. The two pawl elastic members 63 are configured to provide the pawls 62 with an elastic force against the lock tongue 61 to restrict the movement of the lock tongue 61. Therefore, under the action of the two pawl elastic members 63 and the two pawls 62, the movement of the lock tongue 61 is restricted and remains locked. The locking rod 64 is connected to the lock tongue 61 and cooperates with the unlocking member 2. Under the drive of the first opening component 31 and the second opening component 32, the unlocking member 2 can drive the lock tongue 61 to overcome the elastic force to unlock the lock.

[0118] According to a second aspect of an embodiment of the present application, a vehicle door is provided, comprising a door body and the lock according to any one embodiment of the first aspect, wherein the lock is arranged on the door body.

[0119] In some embodiments, the vehicle door further includes a first door handle and a second door handle, wherein the first door handle is connected to the first opening assembly 31 of the lock, and the second door handle is connected to the second opening assembly 32 of the lock. Optionally, the first door handle is located on the side of the vehicle door facing outward, i.e., the exterior door handle of the vehicle door, and the second door handle is located on the side of the vehicle door facing inward, i.e., the interior door handle of the vehicle door.

[0120] According to a third aspect of the embodiments of the present application, a vehicle is provided, comprising the vehicle door described in the second aspect. The vehicle may be a fuel vehicle, a plug-in hybrid vehicle, or a new energy vehicle, etc., which is not specifically limited in this disclosure.

[0121] Please combine Figure 1-Figure 7 As shown, the working principle of the lock is described below by taking the lock set on the door of a vehicle as an example.

[0122] like Figure 1 As shown, the lock tongue 61 is kept locked under the action of the two pawl elastic members 63 and the two pawls 62 , and the locking rod 64 is connected to the lock tongue 61 and cooperates with the unlocking member 2 .

[0123] like Figure 2 and Figure 3 As shown, the lock is in the disarmed state. At this time, the linkage mechanism 4 is in the first state, the locking assembly 5 is in the unlocked position, and the first linkage member 41 and the second linkage member 42 remain relatively retracted under the action of the first elastic member 44, so that the first opening assembly 31 and the second opening assembly 32 cooperate with the unlocking member 2. The first door handle is coaxially fixed with the first opening assembly 31. Rotating the first door handle drives the first opening assembly 31 to rotate. The first opening assembly 31 drives the locking rod 64 through the unlocking member 2, which in turn drives the lock tongue 61 to unlock, thereby opening the door. The second door handle is coaxially fixed with the opening structure 321 of the second opening assembly 32. Rotating the second door handle drives the opening structure 321 to rotate. The opening structure 321 pushes the unlocking member 2 to rotate via the first shift block 3221 on the unlocking structure 322, thereby driving the locking rod 64 through the unlocking member 2 to unlock the lock tongue 61, thereby opening the door.

[0124] Electric insurance process: In the insurance release state, combine Figure 2 and Figure 8As shown, the rotary motor 12 of the driving mechanism 1 is energized, and the driving body 13 is driven to rotate clockwise in the first direction for the first stroke through the worm 11. At this time, the hook portion 1311 of the first driving member 131 on the driving body 13 enters the opening of the receiving groove on the first force-bearing portion of the first linkage member 41, and the hook portion 1311 acts on the bottom wall of the receiving groove to push the first linkage member 41 to move leftward. The first linkage member 41 drives the second linkage member 42 to rotate around the first rotating shaft 43, and the elastic potential energy stored in 441 is released and acts on the second linkage member 42, pushing the second linkage member 42 and driving the first linkage member 41 to continue moving leftward, causing the first linkage member 41 and the second linkage member 42 to further expand. Under the action of the first linkage member 41, the first opening component 31 moves away from the unlocking member 2 and disengages. The second linkage member 42 drives the unlocking structure 322 of the second opening component 32 away from the unlocking member 2 through the second shift block 3222. The first shift block 3221 on the unlocking structure 322 disengages from the unlocking member 2, achieving the switch to the second state, thereby placing the lock in the safety state. At the same time, during the safety process, when the linkage mechanism 4 reaches the third state, the rotary motor 12 is powered off and, under the action of the reset elastic member 14, returns counterclockwise in the second direction to the initial position.

[0125] like Figure 4 and Figure 5 As shown, the lock is in the secured state. At this time, the linkage mechanism 4 is in the second state, the locking assembly 5 is in the unlocked position, and the first linkage member 41 and the second linkage member 42 remain relatively extended under the action of the first elastic member 44. The first opening assembly 31 is separated from the unlocking member 2 and disengaged. The first shift block 3221 on the unlocking structure 322 of the second opening assembly 32 is separated from the unlocking member 2 and disengaged. At this time, the first opening assembly 31 cannot drive the unlocking member 2, and the door cannot be opened.

[0126] When the second locking member 42 is unlocked, the first locking member 321 is unlocked and the second locking member 42 is unlocked, thereby unlocking the first locking member 321 and the second locking member 42.

[0127] Electric super lock process: Figure 6 and Figure 7 As shown, after the lock is secured, the rotary motor 12 of the drive mechanism 1 is energized, driving the drive body 13 to rotate clockwise in the first direction through the second stroke via the worm 11. The second driving member 132 on the drive body 13 abuts the locking member 51, pushing the locking member 51 toward the second linkage member 42 to the locked position. The locking member 51, under the action of the third connecting end 521, abuts against one end of the second elastic member 45, limiting the second elastic member 45 from applying force to the second linkage member 42, making the second linkage member 42 unable to be driven by the second opening assembly 32. The linkage mechanism 4 is locked in the second state, and the lock is locked in the secured state. After the super lock is engaged, the rotary motor 12 is de-energized and, under the action of the reset elastic member 14, returns to the initial position counterclockwise in the second direction.

[0128] The process of electrically releasing the super lock and releasing the insurance: the rotating motor 12 of the driving mechanism 1 is energized, and the driving body 13 is driven to rotate counterclockwise in the second direction through the worm 11. The third driving member 133 first abuts against the locking member 51, pushing the locking member 51 away from the second linkage member 42 and driving the third elastic member 52 to rotate around the fourth connection end 522. The locking member 51 is kept in the unlocked position under the action of the third elastic member 52, thereby releasing the super lock; if the driving body 13 is further rotated counterclockwise in the second direction to the end of the third stroke, it is further driven away from its hook through the first driving member 131. One side of the hanging portion 1311 abuts against the second force-bearing portion on the first linkage member 41, thereby pushing the first linkage member 41 to move to the right, driving the second linkage member 42 and the first elastic member 44 to rotate around the first rotating shaft 43, so that the first linkage member 41 and the second linkage member 42 remain relatively retracted under the action of the first elastic member 44, and the first opening component 31 approaches the unlocking member 2 and cooperates. At the same time, the second linkage member 42 moves the first dial block 3221 on the unlocking structure 322 of the second opening component 32, so that the first dial block 3221 approaches the unlocking member 2 and cooperates, completing the release of the safety.
