[0039] As Figures 1 to 17As shown in the figure, the lock drive structure 100 provided by the present invention includes a lock base assembly 10 and a lock tongue assembly 20. The lock base assembly 10 is provided with a first cavity having an opening. Inside the first cavity, a first reset assembly 11 and a first abutting member 12 that are connected to each other are sequentially arranged from inside to outside. The first reset assembly 11 is used to drive the first abutting member 12 to return from the second position to the first position. The lock tongue assembly 20 is provided with a second cavity having an opening. Inside the second cavity, a second reset assembly 21 and a second abutting member 22 that are connected to each other are sequentially arranged from inside to outside. The second reset assembly 21 is used to drive the second abutting member 22 to return from the fourth position to the third position. Wherein, when the first abutting member 12 is located at the second position, the second abutting member 22 is located at the fourth position, and the lock is in the unlocked state. When the first abutting member 12 is located at the first position, the second abutting member 22 is located at the third position, and the lock is in the locked state.

[0040] Specifically, the lock drive structure 100 may include a lock base assembly 10 and a lock tongue assembly 20. The lock base assembly 10 may be provided with a first cavity having an opening (not shown in the figure). Inside the first cavity, a first reset assembly 11 and a first abutting member 12 that are connected to each other are sequentially arranged from inside to outside. The first cavity serves as an installation space for installing the first reset assembly 11 and the first abutting member 12. An opening is provided on the side of the first cavity facing the lock tongue assembly 20, facilitating the abutment of the first abutting member 12 with the second abutting member 22 at the opening. The first reset assembly 11 is used to drive the first abutting member 12 from the second position to the first position. It can be understood that the first position is the initial position of the first abutting member 12, that is, the position when the lock is in the locked state, and the second position is the position when the lock is in the unlocked state.

[0041] The lock tongue assembly 20 may be provided with a second cavity having an opening (not shown in the figure). The second cavity has the same function as the first cavity, that is, it is used to install the second reset assembly 21 and the second abutting member 22. The second reset assembly 21 is used to drive the second abutting member 22 from the fourth position to the third position. Wherein, the fourth position is the position when the lock is in the unlocked state, and the third position is the position when the lock is in the locked state.

[0042] When the lock is in the locked state, the first abutting member 12 is in the first position, the second abutting member 22 is in the third position, and the first abutting member 12 abuts against the second abutting member 22. At this time, if the lock needs to be unlocked, the user can push the first reset assembly 11, and the first reset assembly 11 will push the first abutting member 12 out of the first cavity until the first abutting member 12 is in the second position. At the same time, the second abutting member 22 also moves toward the outside of the first cavity under the action of the first abutting member 12. When the first abutting member 12 is in the second position, the second abutting member 22 is in the fourth position, and the lock is unlocked. The user can open the skylight 200 through other hardware. During the opening process of the skylight 200, the first reset assembly 11 drives the first abutting member 12 to return from the second position to the first position. At this time, the second abutting member 22 is maintained in the fourth position under the action of the second reset assembly 21. When the skylight 200 needs to be locked, the user can pull down the skylight 200 through the hardware. At this time, the second abutting member 22 is squeezed and returns to the second cavity. After the skylight 200 is closed, the second abutting member 22 is driven by the second reset assembly 21 to return from the fourth position to the third position to complete the locking.

[0043] As a further embodiment, a limiting assembly 113 is further included. The limiting assembly 113 includes a limiting plate 1131 and a second elastic assembly 1132. One side of the limiting plate 1131 is connected to the first elastic member 1123, and two ends of the other side of the limiting plate 1131 are respectively provided with the second elastic assembly 1132. The second elastic assembly 1132 is used to be clamped with a limiting groove 14 provided on the first cavity.

[0044] Among them, the limiting assembly 113 may include a limiting plate 1131 and a second elastic assembly 1132. One side of the limiting plate 1131 is connected to the first elastic member 1123, and the second elastic assembly 1132 is provided on the other side of the limiting plate 1131. The limiting plate 1131 can move to the second position under the action of the first elastic member 1123 and return to the first position under the action of the first elastic member 1123. The limiting plate 1131 is also connected to the first abutting member 12 at the same time, and the first abutting member 12 can be driven by the limiting plate 1131 to move back and forth between the first position and the second position. The second elastic assembly 1132 is used to limit the limiting plate 1131 to limit the second abutting member 22 at the second position until the limiting plate 1131 is released under the action of an external force.

[0045] As a further embodiment, the second elastic assembly 1132 includes a second elastic member 1133 and a clamping member 1134. The second elastic member 1133 is horizontally arranged on the limiting plate 1131, and the clamping member 1134 is connected to one end of the second elastic member 1133 close to the first cavity. The clamping member 1134 is used to be clamped with the limiting groove 14.

[0046] Wherein, two ends of the limiting plate 1131 may be respectively provided with a second elastic component 1132. Each second elastic component 1132 may include a second elastic member 1133 and a clamping member 1134. The second elastic member 1133 is horizontally fixed on the limiting plate 1131, and one end of the second elastic member 1133 facing the outside is connected with a clamping member 1134. The clamping member 1134 is used for clamping with the limiting groove 14 at the opening of the first cavity. As Figure 3 and Figure 5 shown, an arc-shaped clamping groove is provided on the side wall at the opening of the first cavity. The arc-shaped clamping groove can cooperate with the clamping member 1134 to realize the clamping of the limiting plate 1131. Among them, the clamping member 1134 may be a sphere.

[0047] When the lock is in the locked state, the limiting plate 1131 is located at the first position. At this time, the inner wall of the first cavity presses the clamping member 1134, and the clamping member 1134 presses the second elastic member 1133, so that the second elastic member 1133 is in a compressed state. When the limiting plate 1131 moves to the second position, at this time, the clamping member 1134 and the limiting groove 14 are in a parallel position. Under the action of the second elastic member 1133, the clamping member 1134 is clamped into the limiting groove 14 to complete the limitation of the limiting plate 1131, and further, the first abutting member 12 can be fixed at the second position.

[0048] As a further embodiment, the lock seat assembly 10 includes a base 13. The base 13 is provided with the first cavity penetrating the base 13. The bottom of the first cavity is provided with the first reset assembly 11. The bottom of the first reset assembly 11 covers the first cavity to close an opening of the first cavity. The top of the first reset assembly 11 is connected with the first abutting member 12.

[0049] Wherein, as Figure 2 and Figure 3 shown, the lock seat assembly 10 may include a base 13. A first cavity penetrating the base 13 may be formed in the middle of the base 13. The bottom of the first cavity is provided with the first reset assembly 11. The bottom of the first reset assembly 11 covers the first cavity to close one of the openings of the first cavity. The top of the first reset assembly 11 is connected with the first abutting member 12 to facilitate driving the first abutting member 12 to move. Among them, as Figure 3 shown, the first abutting member 12 may be a panel.

[0050] As a further embodiment, the first reset assembly 11 includes a housing 111 and a first elastic component 112; one side of the housing 111 covers the first cavity to close the first cavity, and the other side of the housing 111 is provided with the first elastic member 112.

[0051] Wherein, asFigure 5 As shown, the first reset component 11 may include a housing 111. The housing 111 may be rectangular, and the front of the housing 111 covers the first cavity to enclose the first cavity, as Figure 2 shown. An installation groove may be provided on the back of the housing 111, and a first elastic component 112 and a limiting component 113 are provided in the installation groove. One end of the first elastic component 112 may be fixed in the installation groove of the housing 111, the other end of the first elastic component 112 is connected to the limiting component 113, and the limiting component 113 is connected to the first abutting member 12. When the user needs to unlock the lock, the housing 111 can be pressed to drive the first elastic component 112 and the limiting component 113 to move towards the outside of the first cavity. The limiting component 113 abuts against the first abutting member 12, and then the first abutting member 12 can be pushed to move towards the outside of the first cavity. When the first abutting member 12 is in the second position, the first abutting member 12 stops at the second position. At this time, the user releases the hand, and the housing 111 and the first elastic component 112 return to the initial state. When the skylight 200 is in the opening process, the first elastic component 112 pulls the limiting component 113 back to the first position, and then drives the first abutting member 12 back to the first position.

[0052] As a further embodiment, the first elastic component 112 includes a fixed shell 1121, a fixed column 1122 and a first elastic member 1123; one side of the fixed shell 1121 is installed in the housing 111, a fixed groove 1124 is provided on the other side of the fixed shell 1121, the fixed column 1122 is installed in the fixed groove 1124, the first elastic member 1123 is sleeved on the fixed column 1122, and the top of the first elastic member 1123 is connected to the limiting component 113.

[0053] Among them, the first elastic component 112 may include a fixed shell 1121, a fixed column 1122 and a first elastic member 1123, as Figure 5 shown. The fixed shell 1121 is fixed in the housing 111, and two fixed grooves 1124 are arranged side by side in the fixed shell 1121. A fixed column 1122 is provided in each fixed groove 1124. The first elastic member 1123 is sleeved on the fixed column 1122. One end of the first elastic member 1123 is fixedly connected to the fixed column 1122, and the other end of the first elastic member 1123 is connected to the limiting component 113.

[0054] When the user needs to unlock the lock, the user presses the housing 111, and the housing 111 drives the fixed housing 1121, the first elastic member 1123, and the limiting assembly 113 to move toward the outside of the first cavity. When the first abutting member 12 is in the second position, the user releases the housing 111. At this time, under the action of the first elastic member 1123, the housing 111 and the fixed housing 1121 return to the initial position, the limiting assembly 113 and the first abutting member 12 are in the second position, and the first elastic member 1123 is in a stretched state. When the skylight 200 is in the opening process, the first elastic member 1123 pulls the limiting assembly 113 and the first abutting member 12 back to the first position under the action of the elastic restoring force.

[0055] As a further embodiment, the locking tongue assembly 20 includes a locking tongue housing 23, the locking tongue housing 23 is provided with the second cavity, and the second reset assembly 21 and the second abutting member 22 are sequentially arranged in the second cavity from inside to outside.

[0056] Among them, as Figure 6 shown, the locking tongue assembly 20 may include a locking tongue housing 23. A second cavity is provided in the locking tongue housing 23, and the second reset assembly 21 and the second abutting member 22 are sequentially arranged in the second cavity from inside to outside. In the locked state, the second abutting member 22 is in the third position under the action of the second reset member, that is, in the second cavity. At this time, the second abutting member 22 abuts against the first abutting member 12. When unlocking is required, the user presses the first reset assembly 11. Under the push of the first reset assembly 11, the second abutting member 22 exits from the first cavity. At this time, the second reset assembly 21 is in a compressed state. When the skylight 200 needs to be closed, the second reset assembly 21 continues to be compressed under the action of an external force, so that the second abutting member 22 enters the second cavity from the outside. After the skylight 200 is closed, the second reset assembly 21 pushes the second abutting member 22 from the second cavity to the first cavity under the action of the elastic restoring force until the second abutting member 22 abuts against the first abutting member 12.

[0057] As a further embodiment, an abutting portion 24 is provided around the opening of the second cavity, and a protrusion 25 is provided on the abutting portion 24.

[0058] Among them, as Figure 6 shown, an abutting portion 24 is provided at the opening of the second cavity, and a protrusion 25 is provided on each side of the abutting portion 24. The protrusion 25 is used to squeeze the limiting assembly 113 when the skylight 200 is in the opening process, so that the limiting assembly 113 is released from the limiting groove 14, facilitating the second elastic member 1133 to pull the first abutting member 12 from the second position back to the first position.

[0059] As a further embodiment, the second reset assembly 21 includes a fixing plate 211, a connecting portion 212 perpendicular to the fixing plate 211 is provided on the fixing plate 211, a placing groove 213 is formed on the connecting portion 212, a connecting column 214 for connecting with the second abutting member 22 is provided on the placing groove 213, and a third elastic member 215 is sleeved on the connecting column 214.

[0060] Among them, as Figure 7 and Figure 8 shown, the second reset assembly 21 may include a fixing plate 211, an installation groove is formed on the fixing plate 211, a connecting portion 212 perpendicular to the fixing plate 211 is provided on the installation groove, a placing groove 213 is formed in the middle of the connecting portion 212, a connecting column 214 is provided on the placing groove 213, the connecting column 214 is horizontally placed in the placing groove 213, one end of the connecting column 214 is connected to the second abutting member 22, and a third elastic member 215 is sleeved on the connecting column 214. The third elastic member 215 is in a compressed state both when the second abutting member 22 is in the fourth position and in the first cavity. When the external force is removed, the third elastic member 215 can push the second abutting member 22 to the third position to complete the locking of the lock.

[0061] As a further embodiment, one side of the second abutting member 22 has an inclined surface 221, and the other side of the second abutting member 22 is connected to the connecting column 214.

[0062] Among them, the second abutting member 22 can be a lock tongue, one side of which has an inclined surface 221, the other side of which is connected to the connecting column 214, and a third elastic member 215 is sleeved on the connecting column 214 to facilitate movement under the action of the third elastic member 215. When the lock is in the locked state, the second abutting member 22 is located in the first cavity and abuts against the first abutting member 12. When the user presses the first reset assembly 11, the first abutting member 12 moves from the first position to the second position, and the second abutting member 22 moves from the third position to the fourth position. During the opening process of the skylight 200, the first abutting member 12 returns to the first position, and the second abutting member 22 remains in the fourth position. After the skylight 200 is completely closed, the base inclined surface 15 abuts against the inclined surface 221 of the second abutting member 22, forcing the second abutting member 22 to return to the second cavity. After the skylight 200 is closed, the third elastic member 215 drives the second abutting member 22 to move from the second cavity to the first cavity and abut against the first abutting member 12.

[0063] See Figures 9 to 17 , Figures 9 to 14 is a cross-sectional view of the lock transmission structure 100 in different states, Figures 15 to 17 is a structural diagram of the skylight 200 in different states. As Figure 11 and Figure 12 shown,Figure 11 and Figure 12 is a cross-sectional view of the lock when it is in the locked state. As Figure 11 shown, when the lock is in the locked state, the first abutting member 12 is located inside the first cavity, that is, the first position, and the second abutting member 22 is also located inside the first cavity, that is, the third position. When unlocking is required, the user can press the housing 111. At this time, the first abutting member 12 moves to the second position under the push of the housing 111, and the second abutting member 22 moves to the fourth position under the action of the first abutting member 12 to complete the unlocking of the lock, as Figure 9 and Figure 10 shown. When the lock is in the unlocked state, the engaging member 1134 is located in the limiting groove 14 to fix the first abutting member 12 at the second position, so that the first elastic member 1123 cannot rebound. When the skylight 200 is in the opening process, the protrusion 25 on the abutting portion 24 presses the first abutting member 12, so that the engaging member 1134 disengages from the limiting groove 14. After the engaging member 1134 disengages, the first elastic member 1123 pulls the first abutting member 12 back to the first position. At this time, the second abutting member 22 remains stationary at the fourth position. When the skylight 200 is closed, the base inclined surface 15 contacts the inclined surface 221 of the second abutting member 22, forcing the second abutting member 22 to return to the second cavity. After the skylight 200 is closed, the third elastic member 215 drives the second abutting member 22 to move to the third position, that is, inside the first cavity, to complete the locking.

[0064] The present invention automatically completes the locking of the lock by resetting the first abutting member from the second position to the first position through the first reset assembly and resetting the second abutting member from the fourth position to the third position through the second reset assembly, improving convenience.

[0065] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or replacements, and these modifications or replacements should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
