Description

Technical Field

[0001] The present application relates to the field of locks, and in particular to an emergency unlocking structure of an electric sliding door lock. Background Art

[0002] Electric sliding doors are widely used in building doors and windows due to their space-saving and convenient opening and closing features. Their locking system typically consists of a lock base assembly on the movable door leaf and a locking motor on the fixed frame, with locking achieved by the engagement of a lock hook with a lock slot. Traditional locks rely on a handle or motor-driven transmission mechanism for automatic unlocking. However, in the event of a fault such as rust on the lock base assembly, a broken transmission component, or a stuck lock hook, the automatic unlocking function fails. In these cases, the user must forcibly destroy the lock or dismantle the door leaf, which is not only difficult to operate but can also cause permanent damage to the lock body, seriously affecting safety and maintenance efficiency.

[0003] To address the aforementioned faults, existing technologies offer two manual unlocking solutions: 1. An exposed pull ring is provided on the outside of the movable sash, with a wire rope directly locking the lock slot assembly. Pulling the pull ring forces the lock slot to move, disengaging the lock hook. 2. A through hole is provided on the surface of the movable sash, with an axially movable push rod installed in the hole. When the lock fails, a tool is inserted into the through hole to push the push rod, forcing the lock slot to move and unlock. However, while these solutions can achieve manual unlocking, they all have significant drawbacks:

[0004] 1. The external pull ring is exposed to the environment for a long time and is prone to deformation and rust due to rain erosion or external force collision; the pull ring protrudes from the surface of the door leaf, and there is a risk of accidental unlocking; the wire rope is prone to breakage after bending fatigue, losing its emergency function.

[0005] 2. The push hole destroys the sealing of the door leaf, causing rainwater to seep in and corrode the internal mechanism; the push rod has no guide structure and is prone to deflection and jamming when pushed.

[0006] Therefore, it is necessary to provide a hidden emergency unlocking structure of an electric sliding door lock that prevents mis-triggering. Summary of the Invention

[0007] In view of this, it is necessary to provide a hidden emergency unlocking structure of an electric sliding door lock that prevents false triggering to solve the above problems.

[0050] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0051] It should be noted that when a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component.

[0052] An embodiment of the present application provides an emergency unlocking structure for an electric sliding door and window lock, which is provided on a movable sash, wherein the movable sash is slidably provided on a fixed frame. The emergency unlocking structure for the sliding lock includes:

[0053] a lock seat assembly, disposed opposite to the locking motor provided on the fixed frame, the lock seat assembly having a lock slot, wherein when the lock slot is in a locked position, a lock hook of the locking motor can extend into the lock slot and engage with the lock slot to lock the movable fan and the fixed frame;

[0054] a transmission member, movably disposed on the movable fan along a first direction, and having one end connected to the locking slot;

[0055] The unlocking component includes a manual unlocking member embedded in the movable fan, and the manual unlocking member is in transmission connection with the transmission member; wherein, operating the manual unlocking member drives the transmission member to move along the first direction, so that the lock slot disengages from the locked position and the lock slot and the lock hook are misaligned, and the movable fan and the fixed frame are in a normally open state.

[0056] The above-mentioned emergency unlocking structure of an electric sliding door lock is composed of a lock seat assembly, a transmission member and an unlocking assembly. The lock seat assembly is engaged with the lock hook of the locking motor of the fixed frame to achieve locking; the transmission member is arranged on the movable leaf along the first direction, and one end is connected to the interlocking groove; the manual unlocking member of the unlocking assembly is embedded in the hollow inside the movable leaf, and the manual unlocking member and the transmission member are connected by transmission. Operate the manual unlocking member and drive the transmission member to disengage the lock hook from the lock slot to unlock. This avoids the problems of erosion, deformation and rust caused by long-term exposure to rainwater, and also eliminates the risk of accidental unlocking caused by protruding door leaf surface, greatly improving the safety and reliability of the lock. By adopting a manual unlocking member, even in the case of motor power failure or circuit failure, unlocking can still be achieved by operating the manual unlocking member, solving the problem of traditional locks being difficult to unlock in failure scenarios.

[0057] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0058] according to Figures 1-6 In an embodiment of the present application, an emergency unlocking structure 100 of an electric sliding door lock is provided, which is arranged on a movable fan 1, and the movable fan 1 is slidably arranged on a fixed frame 2. The emergency unlocking structure of the sliding lock includes: a lock seat assembly 10, a transmission member 20 and an unlocking assembly 30.

[0059] Among them, the lock seat assembly 10 is arranged opposite to the locking motor 200 provided on the fixed frame 2, and the lock seat assembly 10 has a lock slot 11. When the lock slot 11 is in the locked position, the lock hook 201 of the locking motor 200 can extend into the lock slot 11 and engage with the lock slot 11 to lock the connection between the movable fan 1 and the fixed frame 2; the transmission member 20 is movably provided on the movable fan 1 along the first direction F1, and one end is connected to the lock slot 11; the unlocking assembly 30 includes a manual unlocking member 31 embedded in the hollow of the movable fan 1, and the manual unlocking member 31 is transmission-connected to the transmission member 20; wherein, operating the manual unlocking member 31 drives the transmission member 20 to move along the first direction F1, so that the lock slot 11 is disengaged from the locked position, and the lock slot 11 is misaligned with the lock hook 201, and the movable fan 1 and the fixed frame 2 are in a normally open state.

[0060] Specifically, it should be noted that the movable sash 1 has a door frame capable of mounting glass, which has a cavity within it. The lock base assembly 10, transmission member 20, and unlocking assembly 30 are all mounted on the door frame within the cavity within the movable sash 1. This prevents the lock from being exposed to the outside environment, preventing it from being corroded by rain or accidentally activated, and extending its service life. The locked position is when the lock base assembly is in its initial state and the locking motor drives the lock hook to move, allowing the lock slot to directly engage with the lock hook.

[0061] It should be noted that, in the normally open state, the movable fan and the fixed frame cannot be closed, that is, the movable fan and the fixed frame can be opened at any time.

[0062] Furthermore, the lock base assembly 10 is fixed to the edge door frame of the movable sash 1 by means of bolts, screws, or any other structure. The lock slot 11 serves as the engaging cavity for the lock hook 201. The lock base assembly 10 and the locking motor 200 are spatially aligned to ensure that the lock hook 201 is accurately inserted into the lock slot 11 and to control the movement of the lock hook 201 to engage or disengage with the lock slot 11. The lock hook 201 is an "L"-shaped structure, one end of which can be inserted into the lock slot 11 and complete the engagement, thereby connecting the movable sash 1 and the fixed frame 2 to complete the door closing.

[0063] It should be noted that by driving the movable sash 1 toward the fixed frame 2, the frame of the movable sash 1 is brought into contact with the fixed frame 2, thereby performing the door closing action. The locking hook 201 on the locking motor 200 is controlled by the motor drive. In the embodiment of the present application, the motor drives the locking hook 201 to reciprocate in the first direction F1, thereby causing the locking hook 201 to disengage from or engage with the locking slot 11. After the locking hook 201 extends into the locking slot 11, further door opening actions between the movable sash 1 and the fixed frame 2 are prevented.

[0064] Furthermore, the transmission member 20 serves as a bridge component connecting the unlocking assembly 30 and the lock base assembly 10. The unlocking assembly 30 and the lock base assembly 10 are located on the same frame. Through the connection of the transmission member 20, the driving force generated by the unlocking assembly 30 is transmitted through the transmission member 20 to the lock slot 11 on the lock base assembly 10, reducing energy loss during the transmission process. Compared with traditional push-type unlocking structures, this can avoid deflection and jamming, making the unlocking operation smoother. The first direction F1 is the direction of movement installed on the frame of the movable sash 1, that is, perpendicular to the sliding direction of the movable sash 1 toward the fixed frame 2.

[0065] The manual unlocking member 31 is connected to the transmission member 20, primarily for receiving manual operating force and converting it into a moving force for the transmission member 20. Compared to electric unlocking solutions, this solution relies entirely on a mechanical structure, requiring no power supply or circuitry. This solves the problem of the lock hook 201 not being able to disengage from the lock slot 11 in time due to a power outage or circuit failure in the locking motor 200, thus hindering the opening of the electric sliding door.

[0066] In a specific embodiment, the transmission member 20 includes a transmission rod 21 and a transmission column 22 .

[0067] Among them, the transmission rod 21, the lock slot 11 is opened on the transmission rod 21; the transmission column 22 is provided at one end of the transmission rod 21 away from the lock slot 11, and the transmission column 22 is extended along a length direction perpendicular to the transmission rod 21, and the transmission column 22 is transmission-connected to the manual unlocking member 31.

[0068] Specifically, the transmission rod 21 is a rod-shaped structure. In the embodiment of the present application, the transmission rod 21 includes a first rod and a second rod. The first rod and the second rod are fixedly connected by screws, bolts, screws and other structures, and the first rod and the second rod are located on the same horizontal axis. The first rod is used to open the lock slot 11 and cooperate with the lock seat assembly 10 to form an integral structure. The second rod is used to connect the unlocking assembly 30. Through the connection between the first rod and the second rod, the lock seat assembly 10 is connected to the unlocking assembly 30, and the driving force is transmitted.

[0069] The transmission column 22 is vertically fixed to the end of the transmission rod 21 and forms a T-shaped structure, which converts the movement of the manual unlocking member into axial movement of the transmission rod 21, avoiding eccentric load caused by oblique force component.

[0070] In one embodiment, the manual unlocking member 31 includes a lock core 311 , a transmission gear 312 , a lock tongue 313 and a guide transmission assembly 314 .

[0071] Among them, the lock core 311 is rotatably provided on the movable fan 1; the transmission gear 312 is arranged opposite to the lock core 311; the lock tongue 313 is connected to the lock core 311 at one end and connected to the transmission gear 312 at the other end to drive the transmission gear 312 to rotate; the guide transmission assembly 314 is meshed and connected with the transmission gear 312, and the guide transmission assembly 314 is connected to the transmission member 20, so that the rotation of the transmission gear 312 drives the guide transmission assembly 314 to move along the first direction F1.

[0072] Specifically, the lock cylinder 311 is designed for key engagement. Its keyhole is exposed outside the movable door 1. By using and rotating the key, the lock cylinder 311 synchronizes the rotation of the lock tongue 313. A D-shaped or flat-shaped axial hole is provided at the rear of the lock cylinder 311, creating an interference fit with the non-circular axial hole of the lock tongue 313. One end of the lock tongue 313 is inserted into the axial hole of the lock cylinder 311, while the other end engages with a groove on the end face of the transmission gear 312, achieving torque transmission.

[0073] In the embodiment of the present application, an axial hole that engages with the lock tongue 313 is opened at the center point of the transmission gear 312. The lock tongue 313 is inserted into the axial hole of the transmission gear 312, so that the transmission gear 312 can rotate around the axial hole at the center point.

[0074] The meshing connection between the guide transmission assembly 314 and the transmission gear 312 allows the guide transmission assembly 314 to convert the rotational motion of the transmission gear 312 into a linear motion along the first direction F1 , thereby driving the movement of the transmission member 20 .

[0075] In one embodiment, the guide transmission assembly 314 further includes a rack 3141 , a driving rod 3142 and a fork lever 32 .

[0076] Among them, the rack 3141 meshingly connected with the transmission gear 312, the rack 3141 is arranged parallel to the first direction F1; the driving rod 3142, the rack 3141 is arranged on the driving rod 3142; the fork lever 32, the fork lever 32 is extended along a length direction perpendicular to the driving rod 3142, one end of the fork lever 32 is arranged on the driving rod 3142, and the other end is clamped with the transmission column 22.

[0077] Specifically, the gear module on the transmission gear 312 matches the number of gears on the rack 3141. In the embodiment of the present application, the axially movable end of the processing rack 3141 is fixed to the driving rod 3142 by welding, thereby reducing the meshing wear between the transmission gear 312 and the rack 3141, and affecting the transmission of force. The meshing connection between the rack 3141 and the transmission gear 312 drives the movement of the driving rod 3142.

[0078] The rack 3141 is arranged on an axial line parallel to the first direction F1. The rotational movement of the lock tongue 313 drives the rotational movement of the coaxial transmission gear 312, so that the rack 3141 engaged with the transmission gear 312 moves along the first direction F1. The rack 3141 drives the drive rod 3142 to move along the first direction F1 together with the fork lever 32.

[0079] It should be noted that the one end of the clamping transmission column 22 on the fork lever 32 is a "U" shaped opening structure, the transmission column 22 is directly inserted through the "U" shaped opening, and the fork lever 32 and the transmission column 22 are perpendicular to each other, so that the force of the fork lever 32 in the first direction F1 is transmitted to the transmission rod 21 through the transmission column 22, and then the lock slot 11 provided on the transmission rod 21 is driven to move.

[0080] In summary, the movement of the manual unlocking part 31 is converted into the linear movement of the transmission part 20 in the first direction F1 by the manual unlocking part 31. The fork lever 32 pushes the transmission column 22 through the clamping structure, the transmission column 22 drives the transmission rod 21 to move in the first direction F1, and finally makes the lock slot 11 displace, realizes the separation of the lock hook 201 from the lock slot 11, and thus completes the unlocking of the lock closed motor 200 and the lock seat assembly 10, and then the movable fan 1 can be driven to move in the door opening direction.

[0081] In a specific embodiment, the unlocking assembly 30 further comprises an outer sealing plate 33, an inner sealing plate 34 and a first shell 35.

[0082] The outer sealing plate 33 is exposed on the outer side of the movable fan 1 and is parallel to the surface of the movable fan 1, and the lock cylinder 311 is arranged in the inner cavity of the outer sealing plate 33 facing the movable fan 1. The inner sealing plate 34 is arranged opposite to the outer sealing plate 33. The first shell 35 and the inner sealing plate 34 form an accommodation cavity, and the transmission gear 312 and the guide transmission assembly 314 are arranged in the accommodation cavity. The first shell 35 is provided with a sliding groove 351 extending in the first direction F1, and the sliding groove 351 is arranged on the side of the shell away from the inner sealing plate 34. The fork lever 32 is arranged in the sliding groove 351 and moves in the sliding groove 351.

[0083] Specifically, the outer surface of the outer sealing plate 33 is flush with the outer side of the movable fan 1, realizing the smooth design on the movable fan 1, so that the movable fan 1 is more beautiful in appearance. The inner side of the outer sealing plate 33 is provided with a lock cylinder 311 mounting groove, and only the key hole used for cooperating with the lock cylinder 311 is exposed, so that rain and dust are blocked by the outer sealing plate 33 and cannot contact the internal structure of the lock cylinder 311. The outer side of the movable fan 1 is free of protruding parts, avoiding accidental unlocking caused by hooking or collision.

[0084] It should be noted that the first shell 35 is a three-side enclosed open shell, the open end of which is sealed and connected with the inner sealing plate 34 to form a closed accommodation cavity. The first shell 35 and the inner sealing plate 34 can be fixedly connected by bolts, screws, screws and the like.

[0085] The sliding groove 351 is used to provide a limited space for the fork lever 32 to move, limiting the movement range and direction of the fork lever 32 connected to the driving rod 3142 within the sliding groove 351, ensuring that the fork lever 32 can only move in a straight line along the first direction F1, avoiding the fork lever 32 from deflecting and getting stuck during the movement.

[0086] To summarize, when manual unlocking is required, a key is inserted into the lock hole of the lock cylinder 311 within the inner cavity of the outer cover 33 and the key is rotated to rotate the lock cylinder 311. The lock cylinder 311 rotates the lock tongue 313, the other end of which engages with the end face groove of the transmission gear 312, thereby driving the transmission gear 312 to rotate about the axial hole at the center point. Because the rack 3141 in the guide transmission assembly 314 is meshed with the transmission gear 312, the rotational motion of the transmission gear 312 is converted into linear motion of the rack 3141 along the first direction F1. The rack 3141 is mounted on the drive rod 3142, thereby driving the drive rod 3142 to move in the first direction F1. The fork lever 32 is mounted on the drive rod 3142. As the drive rod 3142 moves, the fork lever 32 moves in the first direction F1 within the sliding slot 351 of the first housing 35. The fork lever 32 is engaged with the transmission post 22 of the transmission member 20. The movement of the fork lever 32 pushes the transmission post 22, which in turn drives the transmission rod 21 to move in the first direction F1. The transmission rod 21 defines a lock slot 11. The movement of the transmission rod 21 displaces the lock slot 11, disengaging the lock hook 201 of the locking motor 200 from the lock slot 11. This unlocks the locking motor 200 and the lock base assembly 10, thereby driving the movable door 1 to move in the door opening direction.

[0087] In a specific embodiment, the lock base assembly 10 further includes a second housing 12 and a reset assembly 13 .

[0088] Among them, the second shell 12, the transmission rod 21 slides in the second shell 12; the reset component 13, one end of which is connected to the inner wall of the shell, and the other end is connected to the transmission rod 21, and the reset component 13 is arranged in the shell at one end away from the transmission column 2.

[0089] Specifically, the second shell 12 provides a sliding space for the transmission rod 21, so that the transmission rod 21 can slide therein along the first direction F1. The reset component 13 is an elastic compression spring, and the stretching or compression direction of the compression spring is in the same direction as the first direction F1. When the transmission rod 21 is pulled and moved, the compression spring is compressed or stretched to produce elastic deformation. During the movement of the transmission rod 21, the elastic deformation of the reset component 13 can play a buffering role, reduce the impact force between the transmission rod 21 and the first shell 35, and reduce the wear and damage risk of components. When the transmission rod 21 is pulled, after the transmission rod 21 moves along the first direction F1, the compression spring is arranged between the inner wall of the second shell 12 and the transmission rod 21, thereby being compressed and deformed.

[0090] In a specific embodiment, the second shell 12 has a blocking portion 121 therein, and the blocking portion 121 is formed to extend along a shell surface perpendicular to the second shell 12 ; the transmission rod 21 has a first limiting groove 211 , and the blocking portion 121 slides in the first limiting groove 211 .

[0091] Specifically, the blocking portion 121 and the second housing 12 are integrally connected, minimizing offset when the blocking portion 121 collides with the first limiting groove 211, thereby improving the direction and accuracy of transmission. It should be noted that the length of the first limiting groove 211 is coaxial with the first direction F1. The first limiting groove 211 also restricts linear motion of the transmission rod 21 to a set range, thereby ensuring that the lock slot 11 can accurately engage and disengage with the lock hook 201, improving the unlocking and locking operation of the lock.

[0092] In a specific embodiment, the lock slot 11 has an extension slot 111 and a movable slot 112 formed from the transmission rod 21 along a first direction parallel to the first direction F1, the extension slot 111 is arranged toward the lock hook 201, and the extension slot 111 is connected to the movable slot 112; wherein, the groove diameter formed by the extension slot 111 along the first direction F1 is smaller than the groove diameter formed by the movable slot 112 along the first direction F1.

[0093] Specifically, the insertion slot 111 is the starting point for the lock hook 201 to enter the lock slot 11. When the lock is locked, the lock hook 201 first enters the insertion slot 111, preparing to subsequently enter the movement slot 112. The movement slot 112 is connected to the insertion slot 111. When the transmission rod 21 moves, the movement slot 112 and the insertion slot 111 provide space for the lock hook 201 to move, thereby achieving the unlocking and locking functions of the lock. When the transmission rod 21 moves, the lock hook 201 moves relative to the movement slot 112, changing the relative position of the lock hook 201 and the lock slot 11.

[0094] After the lock hook 201 enters the movable groove 112 from the insertion groove 111, the lock hook 201 is controlled to move in the first direction F1, so that the hook portion of the lock hook 201 can be limited by the boundary of the insertion groove 111, thereby realizing the locking function of the lock. After the lock hook 201 moves within the movable groove 112 and completes the locking function with the lock groove 11, the movable door 1 is prevented from moving in the opening direction.

[0095] The lock hook 201 is an "L"-shaped structure. After its clamping end moves along the first direction F1, it extends into the inner groove of the movable groove 112 and can be limited by the extending groove 111 to prevent the lock hook 201 from moving in the horizontal direction, that is, moving in the opening direction of the movable fan 1.

[0096] In this embodiment of the present application, the movement of the transmission rod 21 drives the lock slot 11, changing the relative position of the lock hook 201 with respect to the lock slot 11. The lock hook 201 gradually disengages from the lock slot 11, ultimately being positioned within the notch of the insertion slot 111. At this point, the lock hook 201 is no longer constrained by the boundaries of the insertion slot 111, and the movable door 1 can move in the opening direction, thereby unlocking the door.

[0097] In a specific embodiment, the inner sealing plate 34 is provided with a second limiting groove 341, which is extended along the first direction F1; the guide transmission assembly 314 also has a positioning column 3143, which is arranged on the side of the guide transmission assembly 314 away from the fork lever 32, and the positioning column 3143 moves into the second limiting groove 341.

[0098] Specifically, because the positioning post 3143 on the guide transmission assembly 314 moves within the second limiting slot 341 of the inner sealing plate 34, the second limiting slot 341 constrains and guides the positioning post 3143. The positioning post 3143 can only move within the second limiting slot 341, thereby limiting the movement direction of the guide transmission assembly 314 to linear motion along the first direction F1, thereby preventing the guide transmission assembly 314 from deflecting or shaking during movement.

[0099] In a specific embodiment, the end of the positioning column 3143 is provided with an anti-slip protrusion 31431, and the movable end of the second limiting groove 341 is provided with a U-shaped bayonet; the inner width of the U-shaped bayonet is smaller than the diameter of the anti-slip protrusion 31431, and the outer width is larger than the diameter of the anti-slip protrusion 31431, so as to form axial limitation.

[0100] Specifically, the positioning column 3143 plays a key role in limiting the movement range of the drive rod 3142 and providing a movement guide for it. An anti-slip protrusion 31431 is provided at its end. This protrusion is usually circular or other regular shapes and has a certain diameter size. The anti-slip protrusion 31431 increases the structural size of the end of the transmission column 22, providing a basis for subsequent cooperation with the U-shaped bayonet. The second limiting groove 341 extends along the first direction F1 and provides a guide for the movement of components such as the positioning column 3143. The U-shaped bayonet opened at its moving end has an inner side and an outer side to meet the axial limitation requirements of the positioning column 3143 in the second limiting groove 341.

[0101] To sum up, when the movable fan 1 is driven to move in the direction of closing the door, the movable fan 1 moves to fit with the fixed frame 2. At this time, the lock seat assembly 10 on the movable fan 1 fits with the locking motor 200 on the fixed frame 2, and the lock hook 201 of the locking motor 200 extends into the lock slot 11 of the lock seat assembly 10. The motor then controls the movement of the lock hook 201 in the first direction F1, so that the lock hook 201 is engaged with the lock slot 11, completing the closing action of the fixed fan and the movable fan 1.

[0102] When manual unlocking is required, the lock hook 201 of the locking motor 200 remains in its original closed position. Insert the key into the lock cylinder 311 in the inner cavity of the outer seal plate 33 and rotate the key to rotate the lock cylinder 311. The lock cylinder 311 rotates the lock tongue 313. The other end of the lock tongue 313 engages with the end face groove of the transmission gear 312, thereby driving the transmission gear 312 to rotate about the axial hole at the center point. Because the rack 3141 in the guide transmission assembly 314 is meshed with the transmission gear 312, the rotational motion of the transmission gear 312 is converted into linear motion of the rack 3141 in the first direction F1. The rack 3141 is mounted on the drive rod 3142, thereby driving the drive rod 3142 to move in the first direction F1. The fork lever 32 is mounted on the drive rod 3142. As the drive rod 3142 moves, the fork lever 32 moves in the first direction F1 within the sliding slot 351 in the first housing 35. The fork lever 32 is engaged with the transmission post 22 of the transmission member 20. The movement of the fork lever 32 pushes the transmission post 22, which in turn drives the transmission rod 21 to move in the first direction F1. The transmission rod 21 is provided with a lock slot 11. The movement of the transmission rod 21 causes the lock slot 11 to shift. When the lock hook 201 is completely disengaged from the lock slot 111 and positioned within the notch of the insertion slot 111, the lock hook 201 is no longer restricted by the boundary of the insertion slot 111, thereby unlocking the locking motor 200 and the lock base assembly 10, thereby driving the movable door 1 to move in the door opening direction.

[0103] Traditional locks rely on a handle or motor-driven transmission mechanism for automatic unlocking. However, this automatic unlocking function can easily fail in the event of a fault, such as rust on the lock base assembly 10, a broken transmission member, or a stuck lock hook 201. This is especially true if the motor loses power or there's a circuit failure, often preventing the user from properly opening the electric sliding door. The embodiments of the present application utilize a purely mechanical structure, relying entirely on manual operation and mechanical transmission to achieve the unlocking function, without the need for power or circuit support. Therefore, even in the event of a motor power outage or circuit failure, the user can still easily unlock the door by operating the manual unlocking member 31. This solves the problem of traditional locks being difficult to unlock in faulty scenarios, and improves the user-friendliness and emergency response capabilities of the electric sliding door.

[0104] The above-mentioned emergency unlocking structure 100 for an electric sliding door lock is composed of a lock base assembly 10, a transmission member 20, and an unlocking assembly 30. The lock base assembly 10 engages with the lock hook 201 of the locking motor 200 of the fixed frame 2 to achieve locking. The transmission member 20 is arranged on the movable door 1 along the first direction F1, with one end interlocking with the slot 11. The manual unlocking member 31 of the unlocking assembly 30 is embedded in the hollow space of the movable door 1 and is in transmission connection with the transmission member 20. Operating the manual unlocking member 31 and driving the transmission member 20 disengages the lock hook 201 from the lock slot 11 to unlock the door. This avoids corrosion, deformation, and rust caused by long-term exposure to rainwater, and also eliminates the risk of accidental unlocking caused by protruding from the door surface, greatly improving the safety and reliability of the lock. By adopting the manual unlocking member 31, even if the motor loses power or the circuit fails, the lock can still be unlocked by operating the manual unlocking member 31, solving the problem of traditional locks being difficult to unlock in faulty scenarios.

[0105] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
