Description

Technical Field

[0001] This application relates to the field of locks, and more particularly to an emergency unlocking structure for an electric sliding door and window lock. Background Technology

[0002] Electric sliding doors are widely used in the building door and window industry due to their space-saving and convenient opening and closing features. Their locking system typically consists of a lock seat assembly on the moving door and a locking motor on the fixed frame, achieving locking through the engagement of the lock hook and lock groove. Traditional locks rely on a handle or motor-driven transmission mechanism for automatic unlocking, but this automatic unlocking function fails in scenarios such as rust on the lock seat assembly, broken transmission components, or jammed lock hooks. In such cases, users must forcibly damage the lock or disassemble the door, which is not only difficult to operate but also prone to causing permanent damage to the lock body, seriously affecting safety and maintenance efficiency.

[0003] To address the aforementioned malfunctions, existing technologies propose two manual unlocking solutions: 1. An exposed pull ring is installed on the outside of the movable door, connected to a locking groove assembly via a steel wire rope. Pulling the pull ring forcibly displaces the lock groove, causing the lock hook to disengage. 2. A through hole is created on the surface of the movable door, with an axially movable push rod installed within the hole. When the lock malfunctions, a tool is inserted into the through hole to push the push rod, forcing the lock groove to move and unlock. However, while both solutions achieve manual unlocking, they have significant drawbacks: 1. External pull rings are exposed to the environment for a long time and are prone to deformation and rusting due to rainwater erosion or external impact; the pull rings protrude from the door surface, posing a risk of accidental unlocking; the steel wire rope is prone to breakage after bending and fatigue, losing its emergency function.

[0004] Second, the push hole damages the door's seal, allowing rainwater to seep in and corrode the internal mechanisms; the push rod lacks a guide structure, making it prone to deflection and jamming during push-up.

[0005] Therefore, there is a need for a concealed emergency unlocking structure for electrically operated sliding door and window locks that prevents accidental triggering. Utility Model Content

[0006] In view of this, it is necessary to provide an emergency unlocking structure for concealed, accident-preventing electrically operated sliding door and window locks to solve the above problems.

[0007] An embodiment of this application provides an emergency unlocking structure for an electric sliding door / window lock, which is mounted on a movable sash slidably on a fixed frame. The emergency unlocking structure of the sliding lock includes: A locking seat assembly is positioned opposite to a locking motor mounted on the fixed frame. The locking seat assembly has a locking groove. When the locking groove is in the locked position, the locking hook of the locking motor can extend into the locking groove and engage with it to lock the connection between the movable fan and the fixed frame. A transmission component is movably disposed on the movable fan along a first direction, and one end is connected to the locking groove; The unlocking component includes a manual unlocking member embedded in the movable fan, the manual unlocking member being connected to the transmission member; wherein, operating the manual unlocking member drives the transmission member to move along a first direction, so that the lock groove is disengaged from the locked position and the lock groove is misaligned with the lock hook, and the movable fan and the fixed frame are in a normally open state.

[0008] In at least one embodiment of this application, the transmission member includes: A transmission rod, on which the locking groove is formed; A transmission column is located at the end of the transmission rod away from the lock groove. The transmission column extends along the length direction perpendicular to the transmission rod and is connected to the manual unlocking component. In at least one embodiment of this application, the manual unlocking component includes: The lock cylinder is rotatably mounted on the movable fan. The transmission gear is positioned directly opposite the lock cylinder; The locking tongue is connected to the lock cylinder at one end and to the transmission gear at the other end, so as to drive the transmission gear to rotate; A guide transmission assembly is engaged with the transmission gear, and the guide transmission assembly is also connected to the transmission component, so that the rotation of the transmission gear drives the guide transmission assembly to move along the first direction.

[0009] In at least one embodiment of this application, the guide transmission assembly further includes: A rack that meshes with the transmission gear, the rack being formed parallel to the first direction; A drive rod, wherein the rack is mounted on the drive rod; A fork lever extends along the length direction perpendicular to the drive rod, with one end of the fork lever disposed on the drive rod and the other end engaged with the transmission column.

[0010] In at least one embodiment of this application, the unlocking component further includes: An outer sealing plate is exposed on the outer side of the movable fan and parallel to the surface of the movable fan, and the lock cylinder is fitted into the inner cavity of the outer sealing plate facing the movable fan; The inner sealing plate is positioned directly opposite the outer sealing plate; The first housing, together with the inner sealing plate, forms a receiving cavity, and the transmission gear and the guide transmission assembly are disposed within the receiving cavity; The first housing has a sliding groove extending along a first direction. The sliding groove is located on the side of the housing away from the inner sealing plate, and the fork lever passes through and moves within the sliding groove.

[0011] In at least one embodiment of this application, the lock seat assembly further includes: The second housing, within which the transmission rod slides; The reset assembly has one end connected to the inner wall of the housing and the other end connected to the transmission rod, and the reset assembly is located inside the housing at the end away from the transmission rod.

[0012] In at least one embodiment of this application, the second housing has a blocking portion that extends along a surface perpendicular to the second housing. The transmission rod has a first limiting groove, and the blocking part slides within the first limiting groove.

[0013] In at least one embodiment of this application, the lock groove has an insertion groove and a moving groove formed from the transmission rod along a first direction, the insertion groove being disposed toward the lock hook, and the insertion groove communicating with the moving groove; Wherein, the diameter of the groove formed by the extending groove along the first direction is smaller than the diameter of the groove formed by the moving groove along the first direction.

[0014] In at least one embodiment of this application, the inner sealing plate is provided with a second limiting groove, which extends along a first direction; The guide transmission assembly also has a positioning post, which is located on the side of the guide transmission assembly opposite to the fork lever, and the positioning post moves within the second limiting groove.

[0015] In at least one embodiment of this application, the end of the positioning post is provided with an anti-detachment protrusion, and the moving end of the second limiting groove is provided with a U-shaped bayonet. The inner width of the U-shaped latch is smaller than the diameter of the anti-detachment protrusion, and the outer width is larger than the diameter of the anti-detachment protrusion, so as to form an axial limit.

[0016] The aforementioned emergency unlocking structure for an electric sliding door and window lock comprises a lock seat assembly, a transmission component, and an unlocking component. The lock seat assembly engages with the locking hook of the fixed frame locking motor to achieve locking. The transmission component is positioned along a first direction on the movable door sash, with one end having a locking groove. The manual unlocking component is embedded in the hollow interior of the movable door sash, and is connected to the transmission component via a transmission mechanism. Operating the manual unlocking component drives the transmission component, causing the lock hook to disengage from the lock groove and unlock. This avoids corrosion, deformation, and rusting problems caused by long-term exposure to rainwater, and also eliminates the risk of accidental unlocking due to protruding door sash surfaces, greatly improving the safety and reliability of the lock. By employing a manual unlocking component, even in the event of a motor power failure or circuit malfunction, unlocking can still be achieved by operating the manual unlocking component, solving the problem of difficult unlocking of traditional locks in fault scenarios.

[0024] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] 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 may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0026] An embodiment of this application provides an emergency unlocking structure for an electric sliding door / window lock, which is disposed on the movable sash, the movable sash being slidably mounted on a fixed frame. The emergency unlocking structure for the sliding lock includes: A locking seat assembly is positioned opposite to a locking motor mounted on the fixed frame. The locking seat assembly has a locking groove. When the locking groove is in the locked position, the locking hook of the locking motor can extend into the locking groove and engage with it to lock the connection between the movable fan and the fixed frame. A transmission component is movably disposed on the movable fan along a first direction, and one end is connected to the locking groove; The unlocking component includes a manual unlocking member embedded in the movable fan, which is connected to the transmission member. When the manual unlocking member is operated, the transmission member is moved along a first direction to disengage the lock groove from the locked position and to misalign the lock groove with the lock hook. The movable fan and the fixed frame are in a normally open state.

[0027] The aforementioned emergency unlocking structure for an electric sliding door and window lock comprises a lock seat assembly, a transmission component, and an unlocking component. The lock seat assembly engages with the locking hook of the fixed frame locking motor to achieve locking. The transmission component is positioned along a first direction on the movable door sash, with one end having a locking groove. The manual unlocking component is embedded in the hollow interior of the movable door sash, and is connected to the transmission component via a transmission mechanism. Operating the manual unlocking component drives the transmission component, causing the lock hook to disengage from the lock groove and unlock. This avoids corrosion, deformation, and rusting problems caused by long-term exposure to rainwater, and also eliminates the risk of accidental unlocking due to protruding door sash surfaces, greatly improving the safety and reliability of the lock. By employing a manual unlocking component, even in the event of a motor power failure or circuit malfunction, unlocking can still be achieved by operating the manual unlocking component, solving the problem of difficult unlocking of traditional locks in fault scenarios.

[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] according to Figures 1-6 This application provides an emergency unlocking structure 100 for an electric sliding door and window lock, which is mounted on a movable sash 1. The movable sash 1 is slidably mounted on a fixed frame 2. The emergency unlocking structure for the sliding lock includes a lock seat assembly 10, a transmission component 20, and an unlocking component 30.

[0030] The locking assembly 10 is positioned opposite the locking motor 200 mounted on the fixed frame 2. The locking assembly 10 has a locking groove 11. When the locking groove 11 is in the locked position, the locking hook 201 of the locking motor 200 can extend into the locking groove 11 and engage with it to lock the movable fan 1 and the fixed frame 2. A transmission member 20 is movably mounted on the movable fan 1 along a first direction F1, with one end connected to the locking groove 11. An unlocking assembly 30 includes a manual unlocking member 31 embedded in the hollow interior of the movable fan 1. The manual unlocking member 31 is connected to the transmission member 20. Operating the manual unlocking member 31 moves the transmission member 20 along the first direction F1, causing the locking groove 11 to disengage from the locked position and misaligning the locking groove 11 with the locking hook 201. The movable fan 1 and the fixed frame 2 are in a normally open state.

[0031] Specifically, it should be noted that the movable panel 1 has a door frame for installing glass, and the door frame has an installation cavity. The lock seat assembly 10, transmission component 20, and unlocking component 30 are all installed on the door frame within the cavity of the movable panel 1, thus preventing the lock from being exposed to the external environment, avoiding rainwater corrosion or accidental activation, and extending its service life. The locked position is when the lock seat assembly is in its initial state, and the locking motor drives the lock hook to move, allowing the lock groove to directly engage with the lock hook.

[0032] It should be noted that in the normally open state, the movable fan and the fixed frame cannot be closed, meaning that the movable fan and the fixed frame can be opened at any time.

[0033] Furthermore, the lock seat assembly 10 is fixed to the edge of the movable door frame 1 using bolts, screws, or any other means. The lock groove 11 serves as the engaging cavity for the lock hook 201. The lock seat assembly 10 is spatially aligned with the locking motor 200, ensuring that the lock hook 201 is accurately inserted into the lock groove 11 and controlling the movement of the lock hook 201 to engage or disengage with the lock groove 11. The lock hook 201 has an "L"-shaped structure, with one end extending into the lock groove 11 to complete the engaging connection, thereby connecting the movable door 1 and the fixed frame 2 to complete the closing of the door.

[0034] It should be noted that by driving the movable fan 1 to move towards the fixed frame 2, the frame of the movable fan 1 is brought into contact with the fixed frame 2, thus performing the closing action. The locking hook 201 on the locking motor 200 is controlled by the motor drive to move in the direction of its movement. In this embodiment, the motor drives the locking hook 201 to reciprocate along the first direction F1, thereby causing the locking hook 201 to disengage from or engage with the locking groove 11. After the locking hook 201 extends into the locking groove 11, it can prevent the movable fan 1 from performing the opening action between the movable fan 1 and the fixed frame 2.

[0035] Furthermore, the transmission component 20 serves as a bridge assembly connecting the unlocking component 30 and the lock seat assembly 10. The unlocking component 30 and the lock seat assembly 10 are located on the same frame, and through the connection of the transmission component 20, the driving force generated by the unlocking component 30 is transmitted to the lock groove 11 on the lock seat assembly 10, reducing energy loss during transmission. Compared with the traditional push-type unlocking structure, this avoids the phenomenon of skewness and jamming, making the unlocking operation smoother. The first direction F1 is the direction of movement installed on the frame of the movable fan 1, that is, the sliding direction perpendicular to the movable fan 1 towards the fixed frame 2.

[0036] The manual unlocking component 31 and the transmission component 20 are connected by a transmission mechanism, mainly used to receive manual operating force and then convert it into the moving force of the transmission component 20. Compared with the electric unlocking solution, this solution relies entirely on the mechanical structure and does not require power or circuitry, thus solving the problem that the locking hook 201 cannot disengage from the lock groove 11 in time due to a power outage or circuit failure on the locking motor 200, which affects the opening of the electric sliding door.

[0037] In one specific embodiment, the transmission component 20 includes a transmission rod 21 and a transmission column 22.

[0038] The transmission rod 21 has a locking groove 11 formed on it; the transmission column 22 is located at the end of the transmission rod 21 away from the locking groove 11, and extends along the length direction perpendicular to the transmission rod 21. The transmission column 22 is connected to the manual unlocking member 31. Specifically, the transmission rod 21 is a rod-shaped structure. In this embodiment, 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, etc., and the first rod and the second rod are located on the same horizontal axis. The first rod is used to open the rod of the lock groove 11 and cooperates 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 of the first rod and the second rod, the lock seat assembly 10 and the unlocking assembly 30 are connected and the driving force is transmitted.

[0039] 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 part into the axial movement of the transmission rod 21, avoiding the off-center load caused by the oblique component force.

[0040] In one specific embodiment, the manual unlocking component 31 includes: a lock cylinder 311, a transmission gear 312, a lock tongue 313, and a guide transmission assembly 314.

[0041] The lock cylinder 311 is rotatably mounted on the movable fan 1; the transmission gear 312 is positioned opposite the lock cylinder 311; the latch 313 is connected at one end to the lock cylinder 311 and at the other end to the transmission gear 312 to drive the transmission gear 312 to rotate; and the guide transmission assembly 314 is meshed with the transmission gear 312 and is also 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.

[0042] Specifically, the lock cylinder 311 is a key-operated structure. The keyhole of the lock cylinder 311 is exposed on the outside of the movable leaf 1. By using a key and rotating it, the lock cylinder 311 synchronously rotates the bolt 313. The tail of the lock cylinder 311 has a D-shaped or U-shaped shaft hole, which forms an interference fit with the bolt 313 in a non-circular shaft hole. One end of the bolt 313 is inserted into the shaft hole of the lock cylinder 311, and the other end engages with the end face groove of the transmission gear 312 to achieve torque transmission.

[0043] In this embodiment, a shaft hole is provided at the center point of the transmission gear 312 to engage with the locking tongue 313. The locking tongue 313 is inserted into the shaft hole of the transmission gear 312, so that the transmission gear 312 can rotate around the shaft hole at the center point.

[0044] 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 linear motion along the first direction F1, thereby driving the movement of the transmission component 20.

[0045] In one specific embodiment, the guide transmission assembly 314 further includes: a rack 3141, a drive rod 3142, and a fork lever 32.

[0046] The gear 3141 meshes with the transmission gear 312 and is formed parallel to the first direction F1; the drive rod 3142 has the rack 3141 on it; and the fork lever 32 extends perpendicular to the length of the drive rod 3142, with one end on the drive rod 3142 and the other end engaged with the transmission column 22.

[0047] Specifically, the gear module on the transmission gear 312 matches the number of gears on the rack 3141. In this embodiment, the axial moving end of the rack 3141 is fixed to the drive rod 3142 by welding, thereby reducing the meshing wear between the transmission gear 312 and the rack 3141 and the transmission gear 3142. The transmission of influence is reduced by the meshing connection between the rack 3141 and the transmission gear 312, which drives the drive rod 3142 to move.

[0048] The rack 3141 is set on an axial line parallel to the first direction F1. The rotational movement of the locking tongue 313 drives the rotational movement of the coaxial transmission gear 312, causing the rack 3141 meshing with the transmission gear 312 to move along the first direction F1. The rack 3141 drives the drive rod 3142 to move together with the fork lever 32 along the first direction F1.

[0049] It should be noted that one end of the fork lever 32 that engages with the transmission post 22 has a "U" shaped opening structure, through which the transmission post 22 passes directly. Furthermore, the fork lever 32 and the transmission post 22 are set perpendicular to each other, thereby transmitting the force of the fork lever 32 along the first direction F1 to the transmission rod 21 through the transmission post 22, which in turn drives the locking groove 11 on the transmission rod 21 to move together.

[0050] In summary, the motion generated by the manual unlocking component 31 is converted into linear motion of the transmission component 20 along the first direction F1. The fork lever 32 pushes the transmission column 22 through the snap-fit ​​structure, and the transmission column 22 then drives the transmission rod 21 to move along the first direction F1, ultimately causing the lock groove 11 to displace, thereby disengaging the lock hook 201 from the lock groove 11, thus completing the unlocking and locking of the motor 200 and the lock seat assembly 10, and subsequently driving the movable fan 1 to move along the opening direction.

[0051] In one specific embodiment, the unlocking component 30 further includes: an outer sealing plate 33, an inner sealing plate 34, and a first housing 35.

[0052] The outer sealing plate 33 is exposed on the outer side of the movable fan 1 and parallel to the surface of the movable fan 1. The lock cylinder 311 is fitted into the inner cavity of the outer sealing plate 33 facing the movable fan 1. The inner sealing plate 34 is positioned opposite the outer sealing plate 33. The first housing 35 is formed by enclosing the inner sealing plate 34 to form a receiving cavity. The transmission gear 312 and the guide transmission assembly 314 are disposed in the receiving cavity. The first housing 35 has a sliding groove 351 extending along the first direction F1. The sliding groove 351 is located on the side of the housing away from the inner sealing plate 34. The fork lever 32 passes through and moves within the sliding groove 351.

[0053] Specifically, the outer surface of the outer sealing plate 33 is flush with the outer side of the movable fan 1, achieving a smooth design on the movable fan 1 and making the movable fan 1 more aesthetically pleasing. The inner side of the outer sealing plate 33 has a mounting groove for the lock cylinder 311, exposing only the keyhole used to cooperate with the lock cylinder 311, thus preventing rainwater and dust from contacting the internal structure of the lock cylinder 311; the outer side of the movable fan 1 has no protruding parts, avoiding accidental unlocking caused by hooking or collision.

[0054] It should be noted that the first shell 35 is an open shell with three sides enclosed. Its open end is sealed and connected to the inner sealing plate 34 to form a closed receiving cavity. The first shell 35 and the inner sealing plate 34 can be fixedly connected by bolts, screws, screws, etc.

[0055] The sliding groove 351 is used to provide a limiting space for the fork lever 32 to move, limiting the range and direction of movement of the fork lever 32 connected to the drive 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, and avoiding the phenomenon of the fork lever 32 deviating and getting stuck during movement.

[0056] In summary, when manual unlocking is required, the key is inserted into the lock cylinder 311 lock hole in the inner cavity of the outer sealing plate 33, and the key is rotated to rotate the lock cylinder 311. The lock cylinder 311 drives the bolt 313 to rotate, and the other end of the bolt 313 engages with the end face groove of the transmission gear 312, thereby driving the transmission gear 312 to rotate around the shaft hole at the center point. Since 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 the 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 along the first direction F1. The fork lever 32 is mounted on the drive rod 3142, and as the drive rod 3142 moves, the fork lever 32 moves along the first direction F1 within the sliding groove 351 on the first housing 35. The fork lever 32 is engaged with the transmission column 22 of the transmission component 20. The movement of the fork lever 32 pushes the transmission column 22, which in turn drives the transmission rod 21 to move along the first direction F1. A locking groove 11 is provided on the transmission rod 21. The movement of the transmission rod 21 causes the locking groove 11 to displace, thereby disengaging the locking hook 201 of the locking motor 200 from the locking groove 11. This completes the unlocking of the locking motor 200 and the lock seat assembly 10, and then drives the movable fan 1 to move along the opening direction.

[0057] In one specific embodiment, the lock seat assembly 10 further includes a second housing 12 and a reset assembly 13.

[0058] The second housing 12 is in which the transmission rod 21 slides within the second housing 12; the reset assembly 13 is connected at one end to the inner wall of the housing and at the other end to the transmission rod 21, and the reset assembly 13 is located at the end of the housing away from the transmission rod 2.

[0059] Specifically, the second housing 12 provides sliding space for the transmission rod 21, allowing it to slide along the first direction F1 within it. The reset assembly 13 is an elastic compression spring, with its stretching or compression direction aligned with the first direction F1. When the transmission rod 21 is pulled, the compression spring is compressed or stretched, resulting in elastic deformation. During the movement of the transmission rod 21, the elastic deformation of the reset assembly 13 acts as a buffer, reducing the impact force between the transmission rod 21 and the first housing 35, and lowering the risk of wear and damage to the components. When the transmission rod 21 is pulled, after it moves along the first direction F1, the compression spring, positioned between the inner wall of the second housing 12 and the transmission rod 21, is compressed and deformed. In one specific embodiment, the second housing 12 has a blocking portion 121 that extends along a surface perpendicular to the second housing 12; the transmission rod 21 has a first limiting groove 211, and the blocking portion 121 slides within the first limiting groove 211.

[0060] Specifically, the blocking part 121 and the second housing 12 are integrally connected, reducing offset when the blocking part 121 collides with the first limiting groove 211, and improving the direction and accuracy of transmission. It should be noted that the length direction of the first limiting groove 211 is on the same axis as the first direction F1. The first limiting groove 211 also limits the transmission rod 21 to linear movement only within a set range, thereby ensuring that the lock groove 11 can accurately engage and disengage with the lock hook 201, improving the unlocking and locking actions of the lock.

[0061] In one specific embodiment, the locking groove 11 has an insertion groove 111 and a moving groove 112 formed from the transmission rod 21 along a first direction F1. The insertion groove 111 is disposed toward the locking hook 201, and the insertion groove 111 and the moving groove 112 are in communication. The groove diameter formed by the insertion groove 111 along the first direction F1 is smaller than the groove diameter formed by the moving groove 112 along the first direction F1.

[0062] Specifically, the insertion groove 111 is the initial channel for the locking hook 201 to enter the locking groove 11. When the lock is locked, the locking hook 201 first enters the insertion groove 111, preparing for subsequent entry into the moving groove 112. The moving groove 112 is connected to the insertion groove 111. When the transmission rod 21 moves, the moving groove 112 and the insertion groove 111 provide space for the locking hook 201 to move, thereby realizing the unlocking and locking functions of the lock. When the transmission rod 21 moves, the locking hook 201 moves relative to the locking groove 112, changing the relative positional relationship between the locking hook 201 and the locking groove 11.

[0063] After the locking hook 201 enters the moving groove 112 from the insertion groove 111, the locking hook 201 is controlled to move along the first direction F1, so that the hook part of the locking hook 201 can be limited with the boundary of the insertion groove 111, thereby realizing the locking function of the lock. After the locking hook 201 moves in the moving groove 112 and completes the locking function with the locking groove 11, it can prevent the movable fan 1 from moving in the opening direction.

[0064] The locking hook 201 is an "L" shaped structure. Its locking end moves along the first direction F1 and extends into the inner groove of the moving groove 112. It can limit the movement of the locking hook 201 in the horizontal direction, that is, it moves with the opening direction of the movable fan 1.

[0065] In this embodiment, the movement of the transmission rod 21 causes the locking groove 11 to move, changing the relative position of the locking hook 201 and the locking groove 11. The locking hook 201 gradually disengages from the locking groove 11, and finally, the position of the locking hook 201 is located inside the opening of the insertion groove 111. At this time, the locking hook 201 is no longer limited by the boundary of the insertion groove 111, and the movable fan 1 can move in the opening direction to unlock.

[0066] In one specific embodiment, the inner sealing plate 34 has a second limiting groove 341, which extends along a first direction F1; the guide transmission assembly 314 also has a positioning post 3143, which is located on the side of the guide transmission assembly 314 away from the fork lever 32, and the positioning post 3143 moves within the second limiting groove 341.

[0067] Specifically, since the positioning post 3143 on the guide transmission assembly 314 moves within the second limiting groove 341 of the inner sealing plate 34, the second limiting groove 341 constrains and guides the positioning post 3143. The positioning post 3143 can only move within the second limiting groove 341, thereby restricting the direction of movement of the guide transmission assembly 314, making it only able to move in a straight line along the first direction F1, thus preventing the guide transmission assembly 314 from deviating or shaking during movement.

[0068] In one specific embodiment, the end of the positioning post 3143 is provided with an anti-detachment protrusion 31431, and the moving 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-detachment protrusion 31431, and the outer width is larger than the diameter of the anti-detachment protrusion 31431, so as to form an axial limit.

[0069] Specifically, the positioning post 3143 plays a crucial role in limiting the movement range of the drive rod 3142 and providing guidance for its movement. An anti-detachment protrusion 31431 is provided at its end; this protrusion is typically circular or other regular in shape with a certain diameter. The anti-detachment protrusion 31431 increases the structural dimensions of the end of the drive post 22, providing a basis for subsequent engagement with the U-shaped latch. The second limiting groove 341 extends along the first direction F1, providing guidance for the movement of components such as the positioning post 3143. The U-shaped latch at its moving end has an inner and an outer side to meet the axial limiting requirements of the positioning post 3143 within the second limiting groove 341.

[0070] In summary, when the movable fan 1 moves along the closing direction, it moves to be in contact with the fixed frame 2. At this time, the lock seat assembly 10 on the movable fan 1 is in contact with the locking motor 200 on the fixed frame 2. The locking hook 201 of the locking motor 200 extends into the locking groove 11 of the lock seat assembly 10. Then, the movement of the locking hook 201 in the first direction F1 is controlled by the motor, so that the locking hook 201 and the locking groove 11 are engaged, thus completing the closing action of the fixed fan and the movable fan 1.

[0071] When manual unlocking is required, the locking hook 201 of the locking motor 200 remains in the original closed position. Insert the key into the lock cylinder 311's lock hole in the inner cavity of the outer sealing plate 33, and rotate the key to make the lock cylinder 311 rotate. The lock cylinder 311 drives the bolt 313 to rotate, and the other end of the bolt 313 engages with the end face groove of the transmission gear 312, thereby driving the transmission gear 312 to rotate around the shaft hole at the center point. Since 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 along the first direction F1. The fork lever 32 is mounted on the drive rod 3142, and as the drive rod 3142 moves, the fork lever 32 moves along the first direction F1 within the sliding groove 351 on the first housing 35. The fork lever 32 is engaged with the transmission column 22 of the transmission component 20. The movement of the fork lever 32 pushes the transmission column 22, which in turn drives the transmission rod 21 to move along the first direction F1. The transmission rod 21 has a locking groove 11. The movement of the transmission rod 21 causes the locking groove 11 to shift. When the locking hook 201 is completely disengaged from the locking groove 11 and its position is within the opening of the insertion groove 111, the locking hook 201 is no longer limited by the boundary of the insertion groove 111, thereby completing the unlocking and locking of the motor 200 and the lock seat assembly 10, and thus driving the movable fan 1 to move along the opening direction.

[0072] Traditional locks rely on handles or motor-driven transmission mechanisms for automatic unlocking. However, in scenarios involving malfunctions such as corrosion of the lock seat assembly 10, breakage of transmission components, or jamming of the lock hook 201, the automatic unlocking function is prone to failure. This is especially true when the motor loses power or the circuit fails, often preventing users from opening the electric sliding door. This embodiment employs a purely mechanical structure, relying entirely on manual operation and mechanical transmission to achieve the unlocking function, requiring no power supply or circuit support. Therefore, even in the event of a motor power failure or circuit malfunction, users can still easily unlock the door by operating the manual unlocking component 31, solving the problem of difficult unlocking in malfunction scenarios with traditional locks and improving the ease of use and emergency response capabilities of electric sliding doors.

[0073] Therefore, the emergency unlocking structure 100 of the electric sliding door and window lock provided above is composed of a lock seat assembly 10, a transmission component 20, and an unlocking component 30. The lock seat assembly 10 engages with the locking hook 201 of the locking motor 200 of the fixed frame 2 to achieve locking; the transmission component 20 is located on the movable door 1 along the first direction F1, with one end in a locking groove 11; the manual unlocking component 31 of the unlocking component 30 is embedded in the hollow interior of the movable door 1 and is connected to the transmission component 20 via a transmission connection. By operating the manual unlocking component 31, the transmission component 20 is driven to disengage the locking hook 201 from the locking groove 11 to unlock. This avoids the problems of corrosion, deformation, and rusting caused by long-term exposure to rainwater, and also eliminates the risk of accidental unlocking caused by protruding door surfaces, greatly improving the safety and reliability of the lock. By using the manual unlocking component 31, even in the event of a motor power failure or circuit malfunction, unlocking can still be achieved by operating the manual unlocking component 31, solving the problem of difficulty in unlocking traditional locks in fault scenarios.

[0074] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
