[0035] Compared with traditional door locks, smart locks can be connected to the smart home system to provide users with more convenient and user-friendly services. Therefore, more and more people tend to use smart lock systems to replace traditional door locks. However, due to the structural characteristics of traditional door locks, it is very difficult to remove the lock body embedded in the door panel, and it may also cause irreversible damage to the door panel, resulting in the structural strength of the door panel being affected. How to conveniently upgrade and replace traditional door locks with smart lock systems without damaging the door panel is a major technical problem that needs to be solved.

[0036] In order to improve or solve the technical problem, the inventors of the present application have proposed at least the following embodiments after long-term research.

[0037] See also Figure 1 , 2 , 3, 4, Figure 1 It is a schematic diagram of the assembly structure of the smart lock component and the door lock provided in this application. Figure 2 It is a schematic diagram of the assembly structure of the knob assembly and the door lock provided in the present application.

[0038] Figure 3 yes Figure 2 Schematic diagram of the cross-sectional structure of the D-D' section. Figure 4 It is a schematic diagram of the assembly structure of the knob assembly provided by the present application. The embodiment of the present application provides a knob assembly (2), which is used to cooperate with a lock core rotating member (6). The knob assembly (2) may include a knob body (3), the knob body (3) is used to receive external force to rotate, one end of the knob body (3) may be provided with a torsion portion (313), and the other end of the knob body (3) away from the torsion portion (313) may be provided with a mounting groove (33), and the mounting groove (33) is used to limit the lock core rotating member (6) along the rotation direction of the lock core rotating member (6), so that the lock core rotating member (6) can rotate with the rotation of the knob body (3).

[0039] Among them, the torsion portion (313) can be used for the user to hold and apply force to the knob body (3), thereby driving the knob body (3) to rotate. The knob body (3) can also receive the driving force of the driving member. For example, when the knob body (3) is connected to the driving member, the user applies force to the torsion portion (313) to control the knob body (3) to rotate a certain distance, and the driving member drives the knob body (3) to rotate with reference to the direction in which the user rotates the knob body (3). Even if the user does not apply force to the torsion portion (313) later, the knob body (3) can still drive the lock core rotating member (6) to rotate into place under the drive of the driving member. Alternatively, when the driving member receives a driving signal, the driving member will drive the knob body (3) to rotate, thereby driving the lock core rotating member (6) to rotate to achieve unlocking or locking.

[0040] The lock core rotating member (6) can be a structure for driving the lock core of a traditional door lock (7) to rotate, such as a lock core tail rod (62), a key (61), etc. The lock core rotating member (6) can be inserted into the lock core to drive the lock core to rotate, thereby controlling the extension and retraction of the lock tongue of the door lock (7) to achieve unlocking and / or locking of the door lock (7).

[0041] By utilizing the structure provided in this embodiment, the mounting groove (33) on the knob body (3) can limit the lock core rotating member (6), so that when the knob body (3) rotates, the knob body (3) drives the lock core rotating member (6) to rotate synchronously to achieve unlocking and / or locking of the door lock (7). The knob body (3) is used in conjunction with the traditional door lock (7), thereby improving the usability of the knob assembly (2), and it is possible to adapt to the smart lock system without removing the traditional door lock (7), thereby improving the efficiency of upgrading the traditional door lock (7) to the smart lock system, and making the assembly process of the smart lock more convenient.

[0042] In one embodiment, the knob assembly (2) may specifically include a limiter (4). The limiter (4) is arranged corresponding to the mounting groove (33). When the lock core rotating member (6) is inserted into the mounting groove (33), the limiter (4) is used to apply force to the lock core rotating member (6) along a first direction so that the lock core rotating member (6) and the door lock (7) are relatively fixed, so that the lock core rotating member (6) is tightly inserted into the door lock. The lock core rotating member (6) is inserted into the door lock (7) along the first direction, for example, inserted into the lock core of the door lock (7).

[0043] Since the shapes and lengths of the lock core transmission members (6) of different conventional door locks are different, in order to adapt to lock core transmission members (6) of various shapes and lengths, the depth of the installation groove (33) in which the lock core transmission member (6) is inserted in the knob assembly (2) is generally designed to be deep. During the process of opening and closing the door, vibration is inevitably generated, and the lock core rotating member (6) inserted in the door lock (7) may move in the installation groove (33) due to the vibration and become loose from the lock core. When the lock core rotating member (6) produces a certain displacement in the opposite direction to the first direction, it cannot be well connected with the lock core of the door lock (7), causing the lock core rotating member (6) to be stuck in the lock core and unable to effectively drive the lock core to rotate. At this time, if the knob body (3) is rotated to perform unlocking or locking operations, the lock core rotating member (6) may be damaged under the forced force of the knob body (3), causing the entire door lock (7) to be unable to be used normally.

[0044] Through the structure provided in this embodiment, the knob assembly (2) always applies force to the lock core rotating member (6) along the direction in which the lock core rotating member (6) is inserted into the door lock (7), so that the lock core rotating member (6) is limited in the direction in which the lock core rotating member (6) is inserted into the door lock (7) by using the limiting member (4), which can effectively reduce the probability of the lock core rotating member (6) loosening in the door lock (7), so that the knob assembly (2) can cooperate with the traditional door lock (7) more stably.

[0045] In one embodiment, at least part of the limiting member (4) is capable of elastic deformation, and when the lock core rotating member (6) is inserted into the installation groove (33), at least part of the limiting member (4) is stretched or compressed under the action of the lock core rotating member (6) to apply force to the lock core rotating member (6) along a first direction. Specifically, the force applied by the limiting member (4) to the lock core rotating member (6) along the first direction can be an elastic force generated by the elastic deformation of the limiting member (4).

[0046] For lock core rotating parts (6) of different sizes, the depths of the parts inserted into the installation groove (33) can be different, thereby compressing or stretching the limiting part (4) to different degrees, but regardless of the degree of deformation, the limiting part (4) can exert force on the limiting part (4) along the first direction. Therefore, by using the structure provided by this embodiment, the elastic force generated by the elastic deformation of the limiting part (4) is used to limit the lock core rotating part (6) along the first direction, which can not only keep the lock core rotating part (6) in a tightly inserted state in the lock core, but also enable the knob assembly (2) to adapt to lock core rotating parts (6) of different sizes, thereby improving the versatility of the knob assembly (2).

[0047] In one embodiment, the limiting member (4) may specifically include an elastic member and a push member (42), wherein the elastic member is disposed between the push member (42) and the knob body (3). When the lock core rotating member (6) is inserted into the mounting groove (33), the elastic member can be deformed to apply force to the push member (42) along a first direction. The push member (42) is used to press the lock core rotating member (6), and the elastic member is elastically deformed under the extrusion or stretching action of the push member (42) and the knob body (3). The limiting member (4) can specifically limit the lock core rotating member (6) in the first direction through the elastic deformation, thereby adapting to lock core rotating members (6) of different insertion depths (lengths).

[0048] By specifically dividing the limiting member (4) into two parts, namely an elastic member and a resisting member (42), and by generating an elastic force through the elastic member arranged between the knob body (3) and the resisting member (42), the lock core limiting member (4) is limited along a first direction by utilizing the elastic force, thereby being able to adapt to lock core rotating members (6) of different sizes, thereby improving the versatility of the knob assembly (2).

[0049] See also Figure 3 , 5 , 6, Figure 5 yes Figure 4 Schematic diagram of the exploded structure of the knob assembly. Figure 6 yes Figure 4In one embodiment, the elastic member may specifically include a spring (41), the push member (42) includes a first limiting structure (421), the knob body (3) includes a second limiting structure (311), the first limiting structure (421) and the second limiting structure (311) are arranged correspondingly, and the two ends of the spring (41) are respectively limited to the first limiting structure (421) and the second limiting structure (311).

[0050] By setting the first limiting structure (421) and the second limiting structure (311), the spring (41) is limited between the knob body (3) and the abutting member (42), so as to utilize the elastic deformation of the spring (41) to achieve the purpose of limiting the lock core rotating member (6). At the same time, the limiting effect of the first limiting structure (421) and the second limiting structure (311) can also play a certain fixing role on the entire limiting member (4), thereby reducing the probability of the limiting member (4) falling off and causing the knob assembly (2) to fail to work normally, thereby improving the stability of the knob assembly (2).

[0051] In one embodiment, see Figure 6 The push-up member (42) further comprises a push-up beam (423), and a side surface of the push-up beam (423) facing away from the spring (41) is used to push against the lock core rotating member (6). The number of the first limiting structures (421) is at least one, and they are evenly arranged relative to the push-up beam (423), so as to evenly apply force to the push-up beam (423).

[0052] In this embodiment, the push piece (42) is arranged in the knob body (3), and the number of the first limiting structures (421) can be two, and they are respectively arranged at the two ends of the push beam (423). Optionally, the shape of the push beam (423) can be arched or linear. In one embodiment, the push beam (423) is an arched arch beam, and the push piece (42) between the two first limiting structures (421) arches a distance away from the door lock (7) to form an arch beam, so that the arch beam can play a certain limiting role on the lock core rotating member (6), reduce the probability of the lock core rotating member (6) shaking in the installation groove (33), and improve the stability of the knob assembly (2) and the lock core rotating member (6) docking.

[0053] Optionally, the first limiting structure (421), the spring (41) and the second limiting structure (311) are coaxially arranged in a one-to-one correspondence, and the axial direction of the spring (41) is parallel to the first direction. The spring (41) can be stretched or contracted along the first direction under the limiting action of the first limiting structure (421) and the second limiting structure (311), so that the elastic force generated by the spring (41) can be applied to the abutting member (42) and the knob body (3) in parallel with the first direction, thereby improving the stability and efficiency of the limiting member (4) in limiting the lock core rotating member (6) along the first direction.

[0054] In one embodiment, at least one of the first limiting structure (421) and the second limiting structure (311) is a limiting column, and the other includes a first limiting groove (422). The spring (41) is sleeved and fixed on the surface of the limiting column. The first limiting groove (422) is arranged corresponding to the limiting column. When the lock core rotating member (6) is inserted into the installation groove (33), the limiting column is at least partially inserted into the first limiting groove (422).

[0055] In this embodiment, there can also be an intercalation relationship between the first limiting structure (421) and the second limiting structure (311). During the process of compressing the spring (41), when the first limiting structure (421) and the second limiting structure (311) are very close, one of them can be accommodated in the first limiting groove (422) of the other, so that the first limiting structure (421) and the second limiting structure (311) can be partially overlapped to expand the deformation range of the spring (41) and expand the movable area of ​​the push member (42), thereby adapting to more models of lock core rotating members (6) and improving the versatility of the knob assembly (2).

[0056] In one embodiment, the knob body (3) may further include a third limiting structure (34), which is arranged in the mounting groove (33) corresponding to the push member (42) and / or the elastic member, and is used to limit the direction of movement of the push member (42) and / or the direction of deformation of the elastic member.

[0057] Specifically, when the second limiting structure (311) is arranged inside the knob body (3), a third limiting structure (34) can be arranged inside the knob body (3), and the third limiting structure (34) is used to limit the direction of movement of the push member (42) and / or the direction of deformation of the elastic member, thereby controlling the direction in which the push member (42) applies force to the lock core rotating member (6), making the lock core rotating member (6) less likely to loosen, thereby improving the limiting effect of the knob assembly (2) on the lock core rotating member (6).

[0058] Furthermore, the third limiting structure (34) may specifically include a second limiting groove (341), which is opened on the inner wall of the inner cavity (331) of the knob body (3) along the first direction. On a plane perpendicular to the first direction, the contour shape of the second limiting groove (341) matches the outer contour shape of the abutting member (42), so that the abutting member (42) moves in the inner cavity (331) parallel to the first direction. Thus, the second limiting groove (341) is used to control the direction in which the abutting member (42) applies force to the lock core rotating member (6), so that the lock core rotating member (6) is not easy to loosen, and the limiting effect of the knob assembly (2) on the lock core rotating member (6) can be improved.

[0059] See also Figure 5 , 6 , 7, Figure 7 yes Figure 4 A three-dimensional cross-sectional structural diagram of the section B-B' in FIG. In one embodiment, the knob body (3) includes a knob cover (31) and an adapting sleeve (32), the adapting sleeve (32) having an inner cavity (331), and the knob cover (31) is sealed at one end of the adapting sleeve (32). The elastic member and the abutting member (42) are both arranged in the inner cavity (331), and the elastic member is arranged between the abutting member (42) and the knob cover (31).

[0060] The other end of the adapter sleeve (32) may also be provided with an end cover (322), on which a portion of the mounting groove (33) is opened, and the portion of the mounting groove (33) is communicated with the inner cavity (331), thereby forming a complete mounting groove (33), and the end cover (322) is used to limit the push member (42) from escaping from the inner cavity (331). Figure 6 The radial dimension of the partial installation groove (33) provided on the end cover (322) is smaller than the radial dimension of the abutting piece (42), and the abutting piece (42) moves in the inner cavity (331) at most to abut against the surface of one side of the end cover (322) facing the inner cavity (331), thereby limiting the abutting piece (42) in the inner cavity (331), reducing the probability of the abutting piece (42) falling out of the inner cavity (331), and improving the stability of the knob assembly (2). The end cover (322) and the adapter sleeve (32) can be separately arranged or integrally formed.

[0061] Optionally, the twisting portion (313) can be specifically arranged on a side surface of the knob cover (31) facing away from the inner cavity (331), so that the user can conveniently control the rotation of the knob assembly (2), thereby improving the usability of the knob assembly (2).

[0062] Specifically, the knob cover (31) and the adapter sleeve (32) can be relatively fixed by means of a screw hole (323), a screw (8) and a stud (312). One of the knob cover (31) and the adapter sleeve (32) is provided with a screw hole (323), and the other is provided with a stud (312). The screw (8) is passed through the screw hole (323) and is screwed to the stud (312), thereby relatively fixing the knob cover (31) and the adapter sleeve (32).

[0063] like Figure 7 As shown, the stud (312) can be specifically arranged on the knob cover (31), and the screw hole (323) can be opened on the adapting sleeve (32). Optionally, a thread matching the screw (8) can also be arranged in the screw hole (323), so that the screw (8) can be screwed together to improve the stability of the relative fixation between the knob cover (31) and the adapting sleeve (32).

Fig.10 The present invention is a schematic diagram of the assembly structure of a knob assembly in which the lock core rotating member is a key. In one embodiment, the knob assembly (2) further comprises an adapter (5), one end of which is used for plugging into the lock core rotating member (6), and the other end of which is used for being inserted into the installed groove (33), and the limiting member (4) abuts against the end of the adapter (5) inserted into the installation groove (33), and the installation groove (33) limits the adapter (5) along the rotation direction of the lock core rotating member (6).

[0065] Compared with the key (61), the lock core rotating member (6) such as the lock core tail rod (62) has a smaller portion exposed outside the lock core, which is not convenient for relative fixation with the knob assembly (2). Therefore, an adapter (5) can be provided to connect the knob assembly (2) and the lock core rotating member (6), so that the mounting groove (33) is used to limit the adapter (5) to indirectly limit the lock core rotating member (6), thereby realizing a non-rotating connection between the knob assembly (2) and the lock core rotating member (6), and realizing the applicability of the knob assembly (2) in different installation scenarios.

[0066] In one embodiment, the mounting groove (33) may include a polygonal groove (35) and an expansion groove (36) that are connected to each other.

The drive member may drive the transmission tooth portion (37) to rotate according to the switch lock signal, thereby driving the knob body (3) and the lock core rotating member (6) to rotate. The drive member may include a motor, a gear, etc.

[0069] By providing the transmission tooth portion (37), even if the user does not directly apply force to the knob assembly (2), the knob assembly (2) can still rotate under the drive of the driving member, thereby improving the usability of the knob assembly (2).

[0070] The embodiment of the present application also provides a driving device (1), which can be connected to the lock core rotating member (6) to drive the lock core to rotate and drive the lock tongue to extend and retract, thereby controlling the door lock (7) to unlock and / or lock.
