In summary, the door lock assembly 1 of the present embodiment stacks the second assembly 13 on the first assembly 12 by sleeving the two assemblies. Compared with the prior art, the door lock assembly has the advantages that only one hole needs to be formed in the shell 11, so that the door lock assembly 1 can be ensured to be locked and unlocked, the space occupied by the parts on the door lock shell 11 is reduced, the space utilization rate of the door lock shell 11 is improved, and the appearance plasticity of the door lock panel is increased.

Referring to fig. 4, fig. 4 isbase:Sub>A schematic view of fig. 1 alongbase:Sub>A-base:Sub>A direction according to another embodiment of the present disclosure. In one embodiment, the first rotating member 121 includes a first sub-rotating member 1211 and a second sub-rotating member 1212, which are connected to each other, the first sub-rotating member 1211 is farther from the housing 11 than the second rotating member 131, the second sub-rotating member 1212 penetrates through the housing 11, at least a portion of the second rotating member 131 is sleeved on at least a portion of the second sub-rotating member 1212, a first receiving slot 1211a is formed on a side of the first sub-rotating member 1211 close to the housing 11, and at least a portion of the second sub-rotating member 1212 is disposed in the first receiving slot 1211 a.

The rotation of the first sub-rotation member 1211 can rotate the second sub-rotation member 1212 with respect to the housing 11, so as to move the lock cylinder or the lock tongue connected to the second sub-rotation member 1212.

The first rotating member 121 of the present embodiment further includes a first sub-rotating member 1211 and a second sub-rotating member 1212. The present application does not limit the shapes of the first sub-rotation member 1211 and the second sub-rotation member 1212 as long as the first sub-rotation member 1211 is connected to the second sub-rotation member 1212. Optionally, the second sub-rotating element 1212 has a mounting space 12a. Alternatively, the first sub-rotation member 1211 and the second sub-rotation member 1212 may be integrally formed, or may be separately formed and assembled. Optionally, the connection manner of the first sub-rotation member 1211 and the second sub-rotation member 1212 includes, but is not limited to, a snap connection, a fixed connection, and the like. In the present embodiment, only the first sub-rotation member 1211 and the second sub-rotation member 1212 are fixedly connected to each other for illustration.

By rotating the first sub-rotation member 1211 to rotate the second sub-rotation member 1212 relative to the housing 11, that is, the second sub-rotation member 1212 independently rotates relative to the second rotation member 131, the lock cylinder or the lock tongue connected to the second sub-rotation member 1212 is moved to realize the on-off locking or the back locking.

In addition, a first receiving groove 1211a is formed on a side of the first sub-rotor 1211 close to the housing 11, and at least a portion of the second sub-rotor 1212 is disposed in the first receiving groove 1211 a. It can also be understood that the second sub-rotating member 1212 is connected to the bottom wall of the first receiving groove 1211 a. By providing the first receiving groove 1211a, the manufacturing material and the cost can be reduced, and the internal space of the first sub-rotating member 1211 can be enlarged, thereby providing a foundation for the arrangement of other components of the door lock assembly 1.

Referring to fig. 5, fig. 5 isbase:Sub>A schematic view alongbase:Sub>A directionbase:Sub>A-base:Sub>A of fig. 1 according to another embodiment of the present disclosure. In one embodiment, a side of the second rotating element 131 away from the housing 11 has a second receiving groove 131a, and at least a portion of the second sub-rotating element 1212 is disposed in the second receiving groove 131a.

The first sub-rotor 1211 can drive the second sub-rotor 1212 to slide toward or away from the housing 11, so that at least a portion of the first sub-rotor 1211 is disposed in the second receiving groove 131a, and the second sub-rotor 1212 is connected to the lock cylinder or the lock tongue.

In the present embodiment, the second rotor 131 has a second receiving groove 131a. The second receiving groove 131a provides a basis for the first sub-rotation member 1211 to slide along the axial direction of the second sub-rotation member 1212 toward or away from the housing 11. The first sub-rotation member 1211 can drive the second sub-rotation member 1212 to slide relative to the housing 11, and it can also be understood that a user can slide the first sub-rotation member 1211 and the second sub-rotation member 1212 toward or away from the housing 11 or the second sub-rotation member 1212 (as shown in a direction D2 in fig. 5).

In this embodiment, in the initial state, there is a gap between the lock cylinder or the lock tongue and the second sub-rotor 1212. At this time, since the second sub-rotary piece 1212 is not connected to the lock cylinder or the latch, the rotation of the first sub-rotary piece 1211 cannot control the movement of the lock cylinder or the latch. When the user needs to open or close the lock or unlock the lock, the user may first make the first sub-rotator 1211 drive the second sub-rotator 1212 to slide relative to the second rotator 131 in a direction approaching the housing 11, and at this time, the first sub-rotator 1211 is disposed in the second receiving groove 131a. It can also be understood that the first sub-rotor 1211 and the second sub-rotor 1212 move toward the second rotor 131 to eliminate the gap between the lock cylinder or the lock tongue and the second sub-rotor 1212, so that the second sub-rotor 1212 is connected to the lock cylinder or the lock tongue. Then, the second sub-rotary piece 1212 is rotated relative to the second rotary piece 131 to control the movement of the lock cylinder or the lock tongue, so as to realize the locking and unlocking or the reverse locking. In this embodiment, the second sub-rotating element 1212 needs to slide to connect the lock cylinder or the lock tongue, so as to realize locking and unlocking or locking in reverse, rather than directly rotating to realize locking and unlocking and locking in reverse, thereby improving the distinction degree of the user on unlocking and locking in reverse, and avoiding the user from mistakenly touching the first component 12 to unlock or lock the door lock when rotating the second component 13.

Referring to fig. 6 to 7, fig. 6 is a schematic perspective view of a second rotating member according to an embodiment of the present disclosure. FIG. 7 isbase:Sub>A schematic view along A-A of FIG. 1 according to yet another embodiment of the present application. In one embodiment, the sidewall of the second receiving groove 131a has a step surface 131b, and the step surface 131b is used for contacting with the surface of the first sub-rotor 1211 close to the housing 11.

The second housing groove 131a in the present embodiment has a stepped surface 131b. When the second sub-rotation element 1212 slides relative to the second rotation element 131 toward the direction approaching the housing 11 (as shown in D3 in fig. 7) and the first sub-rotation element 1211 slides to a predetermined distance, the surface of the first sub-rotation element 1211 on the side approaching the housing 11 abuts against the step surface 131b, so as to limit the sliding range of the first sub-rotation element 1211 and improve the stability of the operation of the door lock assembly 1.

Referring to fig. 8 to 9, fig. 8 is a schematic perspective view of a first rotating member according to an embodiment of the present application. FIG. 9 isbase:Sub>A schematic view of FIG. 1 taken along the line A-A according to yet another embodiment of the present application. In one embodiment, the first sub-rotating member 1211 is provided with a projection 1211b on an outer peripheral side away from the second rotating member 131.

When the surface of the first sub-rotor 1211 on the side of the housing 11 abuts against the stepped surface 131b, the surface of the projection 1211b on the side of the housing 11 abuts against the surface of the second rotor 131 on the side away from the housing 11.

In actual production, the projection 1211b and the first sub-rotation member 1211 may be integrally formed, but the projection 1211b and the first sub-rotation member 1211 are artificially named differently for the convenience of understanding. As shown in fig. 9, when the surface of the first sub-rotation member 1211 close to the housing 11 abuts against the step surface 131b, the surface of the projection 1211b close to the housing 11 abuts against the surface of the second rotation member 131 away from the housing 11, so as to further limit the sliding range of the first sub-rotation member 1211 and further improve the stability of the operation of the door lock assembly 1.

Referring to fig. 10, fig. 10 isbase:Sub>A schematic view alongbase:Sub>A directionbase:Sub>A-base:Sub>A of fig. 1 according to another embodiment of the present disclosure. In one embodiment, an orthogonal projection of the first sub-rotor 1211 on the housing 11 coincides with an orthogonal projection of the second rotor 131 on the housing 11.

As shown in the figure, the orthogonal projection of the first sub-rotation member 1211 perpendicular to the housing 11 of the present embodiment coincides with the orthogonal projection of the second rotation member 131 perpendicular to the housing 11, and it can also be understood that the radial dimension (as shown by H1 in fig. 10) of the first sub-rotation member 1211 is equal to the radial dimension (as shown by H2 in fig. 10) of the second rotation member 131. The arrangement makes the first sub-rotation member 1211 flush with the outer peripheral side surface of the second rotation member 131, so that the user feels the same when rotating the first sub-rotation member 1211 and the second rotation member 131, and the situation that the first sub-rotation member 1211 and the second rotation member 131 form a peripheral side surface with a large front part and a small back part or a peripheral side surface with a small front part and a large back part in the direction perpendicular to the housing 11 is avoided, thereby improving the user experience.

Referring to fig. 11, fig. 11 isbase:Sub>A schematic view of fig. 1 alongbase:Sub>A-base:Sub>A direction according to another embodiment of the present disclosure. In one embodiment, the door lock assembly 1 further includes an elastic element 14, the elastic element 14 is sleeved on the second sub-rotating element 1212, and one end of the elastic element 14 is connected to the bottom wall of the first receiving groove 1211a, and the other end is connected to the bottom wall of the second receiving groove 131a.

When the first sub-rotary member 1211 slides in a direction toward the housing 11 with respect to the second rotary member 131, the elastic member 14 is in a compressed state.

In this embodiment, the elastic element 14 is sleeved on the second sub-rotating element 1212 and connects the first sub-rotating element 1211 and the second rotating element 131. When the first sub-rotating member 1211 slides relative to the second rotating member 131 in the direction D3 toward the housing 11, the elastic member 14 is under the external force given by the first sub-rotating member 1211, and is in a compressed state, and the elastic member 14 in the compressed state has a repulsive force. When the external force on the first sub-rotary member 1211 is removed, the first sub-rotary member 1211 carries the second sub-rotary member 1212 to automatically move in a direction away from the housing 11 under the elastic force of the elastic member 14, so that the second sub-rotary member 1212 is separated from the lock cylinder or the latch. The elastic element 14 can release the compressive stress to push the first sub-rotation element 1211 and the second sub-rotation element 1212 to reset, so as to achieve automatic reset and avoid manual operation during reverse reset.

Referring to fig. 5 again, in one embodiment, the first sub-rotor 1211 can drive the second sub-rotor 1212 to slide relative to the second rotor 131, so that the second sub-rotor 1212 is connected to the lock cylinder, and then the second sub-rotor 1212 is rotated relative to the second rotor 131, so that the lock cylinder connected to the second sub-rotor 1212 moves.

The second rotating member 131 can rotate relative to the second sub-rotating member 1212 to move the latch bolt connected to the second rotating member 131.

In this embodiment, the first assembly 12 may control movement of the lock cylinder and the second assembly 13 may control movement of the deadbolt. Alternatively, the first assembly 12 is connected to a lock cylinder and the user can turn the key or knob to rotate the second turnpiece 131 relative to the third turnpiece to effect locking and unlocking. Alternatively, the second component 13 may be directly or indirectly connected to the deadbolt to control movement of the deadbolt. The second sub-rotor 1212 is required to slide to connect with the lock core to realize locking and unlocking, rather than directly rotating to realize locking and unlocking, so as to improve the distinction degree of unlocking and unlocking for the user, and prevent the user from mistakenly touching the first sub-rotor 1211 to rotate to unlock the door lock when the user rotates the second rotor 131 to realize locking.
