[0032] To describe the technical contents, structural features, achieved purposes and effects of the present application in detail, the following will be described in detail in combination with the embodiments and the drawings.

[0033] As Figure 1 and Figure 2 , the embodiment discloses a door lock 100, which can be used on doors in various occasions, such as home doors, doors in caravans, and hotel doors. The door lock 100 comprises a base body 10, a lock head 12 arranged on the base body 10, and a door lock safety clutch device, which is used to limit the free movement of the lock head 12 to avoid directly implementing unlocking through a door handle connected with the lock head in the case of no key, and can automatically monitor whether the door lock is in a locked state.

[0034] As Figures 2 to 4 , the door lock safety clutch device in the embodiment comprises a trigger switch J, a connecting member 9, and a clutch mechanism M.

[0035] For the clutch mechanism M, it is used to approach or move away from the lock head 12 on the door by rotating and swinging to make the lock head 12 in a locked state or a free movement release state. In the embodiment, the clutch mechanism M realizes the control of the lock head 12 through the action of rotating and swinging. When the clutch mechanism M approaches the lock head 12, the lock head 12 abuts against it, so that the lock head 12 is firmly locked; and when the clutch mechanism M moves away from the lock head 12, the lock head 12 is separated from it, so that the lock head 12 can move freely to realize unlocking.

[0036] For the connecting member 9, one end thereof is connected with the clutch mechanism M, and the other end thereof is connected with the trigger switch J. The connecting member 9 is used to control the state of the trigger switch J according to the state of the clutch mechanism M, so that the trigger switch J sends a trigger signal corresponding to the current state of the clutch mechanism M. The state of the clutch mechanism M includes a locked state of abutting against the lock head 12 and a release state of being separated from the lock head 12.

[0037] Specifically, when the clutch mechanism M is in the locked state, the connecting member 9 will keep the trigger switch J closed to send a corresponding first trigger signal; and when the clutch mechanism M is in the release state, the connecting member 9 will disconnect the trigger switch J to send a corresponding second trigger signal.

[0038] In the embodiment, the state of the trigger switch J is controlled according to the state of the clutch mechanism M through the connecting member 9, so as to generate a corresponding trigger signal. That is to say, when the clutch mechanism M is in the locked state, the connecting member 9 will place the trigger switch J in a state, and when the clutch mechanism M is in the non-locked state, the connecting member 9 will place the trigger switch J in another state, so that the trigger switch J can send a trigger signal corresponding to the current state of the clutch mechanism M. Based on this design, the use state of the door lock can be accurately reflected to provide a convenient and safe use experience for users.

[0039] Further, a state indicator K electrically connected with the trigger switch J is arranged for the door lock safety clutch device, such as Figure 8 The state indicator K is used to send a prompt signal corresponding to the trigger signal sent by the trigger switch J. Specifically, the state indicator K can be a voice player, a flashlight, etc.

[0040] On the other hand, as shown in Figures 2 to 7 The clutch mechanism M includes a rotating member 2 and a clutch member 3. The rotating member 2 is connected with the lock cylinder 11 on the door lock, so that the rotating member 2 can rotate following the rotation of the lock cylinder 11. When the key is inserted into the lock cylinder 11, the lock cylinder 11 rotates, thereby driving the rotating member 2 to rotate.

[0041] The clutch member 3 includes a first fixed end 30 and a first movable end 31. The clutch member 3 is pivoted with the base body 10 of the door lock based on the first fixed end 30. A blocking portion 32 is arranged on the first movable end 31, which is used to abut against the lock head 12 on the door lock. The clutch member 3 in the embodiment is a swing structure member which swings based on one end.

[0042] In addition, the lock head 12 is provided with a blocking matching portion 123 which is matched with the blocking portion 32. The blocking portion 32 in the embodiment is a protrusion, and the blocking matching portion 123 is a groove.

[0043] In addition, the first movable end 31 has a first position and a second position. In the first position, the blocking portion 32 abuts against the lock head 12 on the door lock, so as to block the lock head 12 from returning to the unlocking state, that is, to make the door lock in the safety locking state. In the second position, the blocking portion 32 is separated from the lock head 12, so that the lock head 12 can be freely moved, that is, to make the door lock in the opening state. At this time, the door handle connected with the lock head 12 is used to make the door lock exit the locking groove on the door frame, so as to realize the unlocking operation.

[0044] The rotating member 2 is connected with the clutch member 3, so that the rotating member 2 can drive the clutch member 3 to rotate.

[0045] Specifically, the rotating member 2 drives the clutch member 3 to rotate from the first position to the second position through a connecting rod 4.

[0046] Further, the lock head 12 is further provided with a connecting groove 122, such as Figure 8 The connecting groove 122 is used to be connected with the door handle. When the clutch member 3 is in the second position, the door handle is used to drive the lock head 12 to exit the locking groove. That is, when the blocking portion 32 on the clutch member 3 is separated from the lock head 12, the lock head 12 can be exited from the locking groove on the door frame by rotating the door handle.

[0047] In the embodiment, one end of the linkage 9 is connected with the first movable end 31, and the other end of the linkage 9 is connected with the trigger switch J. When the first movable end 31 of the clutch 3 rotates, the linkage 9 is driven to rotate synchronously.

[0048] On the other hand, in some cases, the user wants the lock head 12 to be in the safe state automatically during the keyless operation, that is, the user does not want the first movable end 31 of the clutch 3 to stay in the second position without the key operation. For this purpose, a homing device 5 is arranged for the clutch 3, which is used to provide the clutch 3 with a constant driving force to move to the first position. Through the arrangement of the homing device 5, when the user pulls out the key, the first movable end 31 of the clutch 3 automatically swings to the first position, so that the lock head 12 is in the safe state, which can avoid the lock head 12 being in the free state when the user leaves. In addition, when the lock head 12 is withdrawn from the lock slot on the door frame to make the door open, the homing device 5 can drive the clutch 3 to automatically enter the first position, which can avoid locking the door without the key, and further avoid locking the key in the room.

[0049] Specifically, the clutch 3 is provided with a sliding groove 33 extending from the first fixed end 30 to the first movable end 31. The homing device 5 includes a second fixed end 50 and a second movable end 51, the second fixed end 50 is pivoted to the base 10, and the second movable end 51 is provided with a connecting head 52 matched with the sliding groove 33. The homing device 5 in the embodiment is a swing structure part like the clutch 3, and the homing device 5 is arranged opposite to the clutch 3. The connecting head 52 is in sliding connection with the sliding groove 33, and the sliding groove 33 is provided with a first elastic member 34, one end of the first elastic member 34 is in abutment with the connecting head 52, and the other end of the first elastic member 34 is in abutment with the first fixed end 30 in the sliding groove 33. In the embodiment, when the first movable end 31 of the clutch 3 is in the first position, the first elastic member 34 can be in a natural elongation state or a compressed state, and of course, it is better to be in the compressed state, so that the blocking part 32 on the clutch 3 is in close abutment with the lock head 12.

[0050] When the clutch 3 is driven by the connecting rod 4 to rotate from the first position to the second position, the first movable end 31 of the clutch 3 drives the second movable end 51 of the homing device 5 to rotate away from the lock head 12, so that the connecting head 52 moves along the sliding groove 33 to the direction close to the first fixed end 30, and further compresses the first elastic member 34. Then, when the rotating torque on the rotating member 2 disappears, the elastic restoring force of the first elastic member 34 pushes the connecting head 52 to move toward the direction close to the lock head 12, so that the connecting head 52 drives the first movable end 31 of the clutch 3 to move toward the lock head 12, and finally makes the blocking part 32 on the clutch 3 abut against the lock head 12.

[0051] If the connecting head 52 is in the same straight line with the first fixed end 30 and the second fixed end 50, the elastic restoring force of the first elastic member 34 cannot bring the connecting head 52 into rotation, and at this time, the clutch member 3 is in the dead point. Therefore, the rotation stroke of the clutch member 3 is limited, so that the first movable end 31 cannot pass the region between the first fixed end 30 and the second fixed end 50, that is, as shown in Figure 7 , a first straight line L1 is formed through the first fixed end 30 and the first movable end 31, and a second straight line L2 is formed through the second fixed end 50 and the second movable end 51, and during the rotation of the clutch member 3, the included angle a between the first straight line L1 and the second straight line L2 satisfies the condition P: 0° < a < 180°, and the moving track of the first movable end 31 and the second movable end 51 is always located on the side of the first fixed end 30 and the second fixed end 50 close to the lock head 12.

[0052] During the rotation of the clutch member 3, as long as the included angle a between the first straight line L1 and the second straight line L2 always satisfies the condition P, the clutch member 3 can be prevented from entering the dead point, so that the stability of the working performance of the clutch mechanism M is effectively ensured.

[0053] On the other hand, as shown in Figure 2 and Figure 5 , the side wall of the rotating member 2 is provided with a first lug 20, the clutch member 3 is provided with a second lug 35, and the connecting rod member 4 is connected with the rotating member 2 and the clutch member 3 through the first lug 20 and the second lug 35. In this embodiment, through the setting of the first lug 20 and the second lug 35, the assembly of the connecting rod member 4 with the rotating member 2 and the clutch member 3 is more convenient.

[0054] On the other hand, as shown in Figure 2 and Figure 8 , in order to improve the controllability of the door lock 100, the clutch mechanism M in this embodiment further comprises a driving motor 6, and the driving motor 6 is in transmission connection with the rotating member 2. Through the setting of the driving motor 6, the user can control the driving motor 6 through the password switch J or the remote controller, and then drive the rotating member 2 to rotate through the driving motor 6, so that the trouble of carrying the key is avoided.

[0055] Specifically, the rotating member 2 is sleeved on one end of a rotating shaft 7, the other end of the rotating shaft 7 is used for being inserted with the lock cylinder 11, and the middle part of the rotating shaft 7 is provided with a gear 8 engaged with the driving motor 6.

[0056] On the other hand, as shown in Figure 2 and Figure 4The lock head 12 comprises a main head 120 and a secondary head 121, the main head 120 is in sliding connection with the base 10, and the secondary head 121 is in fixed connection with the main head 120, so that the main head 120 drives the secondary head 121 to move synchronously. In the embodiment, two lock heads 12 are arranged, which are the main head 120 and the secondary head 121, and the secondary head 121 is fixedly connected with the main head 120, so that only one lock cylinder 11 is arranged on the door lock 100, and the two lock heads 12 can be simultaneously controlled to move synchronously, thereby effectively improving the convenience of use.

[0057] When the clutch 3 is separated from the lock head 12, in the case that the door handle is released, the rear end of the lock head 12 is provided with a second elastic member 13, when the lock head 12 is retracted from the lock slot on the door frame, the second elastic member 13 is in a compressed state, so that when the control force on the door handle disappears, the lock head 12 is automatically extended under the elastic restoring force of the second elastic member 13, and the blocking cooperation part 123 and the blocking part 32 on the clutch 3 are in abutment.

[0058] In summary, as shown in the drawings, the application discloses a door lock 100, which comprises a lock head 12, a lock cylinder 11 and a door lock insurance clutch device. The door lock insurance clutch device comprises a trigger switch J, a connecting member 9 and a clutch mechanism M. When the clutch mechanism M approaches or moves away from the lock head on the door lock by rotating and swinging, the trigger switch J is driven to move synchronously by the connecting member 9, so that the trigger switch J sends a trigger signal corresponding to the current state of the clutch mechanism M, and then whether the clutch mechanism M is in a locked state is monitored according to the trigger signal, so as to remind the user whether the door lock on the door is in a locked state, thereby avoiding the embarrassment of forgetting to lock the door.

[0059] The above only discloses the preferred embodiments of the application, and of course cannot limit the scope of the application, therefore, the equivalent changes made according to the patent application scope of the application still belong to the scope covered by the application.
