Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a clamping mechanism and a smart door lock. Background Technology

[0002] As a security barrier for homes, businesses, factories, and other locations, the importance of smart locks is self-evident. The advantage of smart locks over traditional locks lies in their independent inner and outer lock bodies. This design ensures that even if the outer part of the door is damaged, the inner part can still provide protection, effectively preventing unauthorized intrusion.

[0003] Smart door locks are primarily installed on existing mechanical door locks. They require a clamping knob or key to rotate for locking and unlocking. During installation, due to inherent installation errors, the clamping head often rotates with a significant eccentricity relative to the knob or key on the user's mechanical door. This can easily lead to the clamping head failing to rotate or forcibly rotating it, resulting in damage to the smart lock.

[0004] Therefore, there is an urgent need for a product that can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing smart door locks are easily damaged due to the large eccentricity of the clamp.

[0007] The chuck mechanism includes a rotating assembly and a slide adjustment assembly axially connected to the rotating assembly, such that when the rotating assembly rotates and there is eccentricity, the slide adjustment assembly adjusts in a first direction and / or a second direction to reduce the eccentricity; wherein the first direction and the second direction intersect and are both in the radial direction.

[0008] Optionally, the slide adjustment assembly includes a connecting base plate, a slide body, and a retaining seat, wherein the slide body is located between the connecting base plate and the retaining seat, and the connecting base plate is fixed to the rotating assembly;

Each guide groove has a retaining plate on both sides in the radial direction. The retaining plate is fixed to the connecting base plate and / or the retaining seat. The two retaining plates are connected by a return spring so that they can respectively abut against both sides of the guide groove.

[0010] When the rotating assembly is stationary, the return spring causes the two clamping plates to be in a mirror position;

[0011] When the rotating assembly rotates and there is eccentricity, the two clamping plates are offset in opposite directions along the guide groove to adjust the eccentricity of the rotating assembly in the first direction or the second direction.

[0012] Optionally, the slide body has guide grooves on both sides in the axial direction, and the two guide grooves are respectively arranged along the first direction and the second direction;

[0013] Along the axial direction, the clamping plate located on the side of the slide body near the connecting base plate is fixed to the connecting base plate, and the clamping plate located on the side of the slide body near the clamping seat is fixed to the clamping seat.

[0014] Optionally, the two guide grooves are arranged perpendicular to each other.

[0015] Optionally, along the axial direction, the width of the guide groove gradually increases in the direction away from the slide body, and the side of the clamping plate facing the guide groove has an inclined surface that can cooperate with the guide groove.

[0016] Optionally, the guide groove is provided with a clearance groove, and both of the two clamping plates are provided with clearance portions on the side facing the guide groove. The clearance groove communicates with the two clearance portions to form a clearance space for placing the return spring.

[0017] Both of the aforementioned clearance sections are provided with positioning posts, and the two ends of the return spring are respectively sleeved on the two positioning posts.

[0022] The smart lock includes a lock body and the aforementioned clamping mechanism.

[0023] Compared with the prior art, the clamping mechanism and smart door lock provided by this utility model mainly have the following advantages:

[0024] Beneficial effects:

[0025] This clamping mechanism is mainly used in locks (such as smart door locks). It includes a rotating component and a slide adjustment component axially connected to the rotating component. When the rotating component rotates and there is an eccentricity between the knob connected to the rotating component or the key inserted into the rotating component and the rotating component, the slide adjustment component can adjust in a first direction and / or a second direction (the first and second directions intersect and are both in the radial direction) to reduce the eccentricity.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as “length,” “width,” “upper,” “lower,” “left,” “right,” “front,” “rear,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer” indicate orientations or positions based on the orientations or positions shown in the accompanying drawings and are merely for ease of description and should not be construed as limiting the invention.

[0036] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this utility model are intended to cover non-exclusive inclusion; the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. "A plurality of" means two or more, unless otherwise explicitly specified.

[0037] In the description, claims, and accompanying drawings of this utility model, when an element is referred to as "fixed to," "mounted to," "set on," or "connected to" another element, it can be directly or indirectly located on that other element. For example, when an element is referred to as "connected to" another element, it can be directly or indirectly connected to that other element.

[0038] Furthermore, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] This utility model embodiment provides a clamping mechanism 100, which can be mainly applied to locks (such as smart door locks) to drive the rotating assembly 10 to rotate when the knob 13 connected to the rotating assembly 10 or the key inserted into the rotating assembly 10 is rotated, so that the lock is in the open state.

[0040] like Figure 1 and Figure 2As shown, the chuck mechanism 100 includes a rotating assembly 10 and a slide adjustment assembly 20 axially connected to the rotating assembly 10. During the installation of the lock, manual installation is always prone to errors, resulting in a certain amount of eccentricity between the knob 13 connected to the rotating assembly 10 and the rotating assembly 10, and between the key inserted into the rotating assembly 10 and the rotating assembly 10. Therefore, the slide adjustment assembly 20 is mainly used to adjust the aforementioned eccentricity.

[0041] When the knob 13 or key is turned and drives the rotating assembly 10 to rotate, the rotating assembly 10 can drive the slide adjustment assembly 20 to start operating, so that the slide adjustment assembly 20 can be adjusted in the first direction and / or the second direction to reduce the eccentricity between the knob 13 or key and the rotating assembly 10.

[0042] The first direction and the second direction intersect and are both in the radial direction. That is, the chute adjustment assembly 20 can adjust the aforementioned eccentricity in at least one direction in the radial direction. It should be noted that the first direction and the second direction refer to two different directions in the radial direction, rather than two specific directions.

[0043] Optionally, the slide adjustment assembly 20 can be adjusted in a first direction or a second direction to reduce the eccentricity between the knob 13 or key and the rotating assembly 10, that is, the slide adjustment assembly 20 can adjust the aforementioned eccentricity in one direction in the radial direction; or, the slide adjustment assembly 20 can also be adjusted in a first direction and a second direction to reduce the eccentricity between the knob 13 or key and the rotating assembly 10, that is, the slide adjustment assembly 20 can adjust the aforementioned eccentricity in two directions in the radial direction.

[0044] In summary, compared with the prior art, the chuck mechanism 100 has at least the following beneficial effects:

[0045] The clamping mechanism 100 is mainly used in locks (such as smart door locks). When the rotating component 10 of the clamping mechanism 100 rotates and there is an eccentricity between the knob 13 connected to the rotating component 10 or the key inserted into the rotating component 10 and the rotating component 10, the slide adjustment component 20 of the clamping mechanism 100 can be adjusted in the first direction and / or the second direction (the first direction and the second direction intersect and are both in the radial direction) to reduce the eccentricity. This ensures that the knob 13 or the key and the rotating component 10 can rotate concentrically relative to each other, thereby effectively avoiding the problem that the clamping mechanism 100 cannot rotate or that the lock with the clamping mechanism 100 is damaged due to forced rotation. This effectively improves the usability and service life of the lock with the clamping mechanism 100, providing users with a better user experience.

[0046] To enable those skilled in the art to better understand the present invention, the following will be described in conjunction with the appendix. Figures 1 to 4The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0047] In some embodiments, such as Figures 2 to 4 As shown, the slide adjustment assembly 20 includes a connecting base plate 21, a slide body 22, and a retaining seat 23. The slide body 22 can be located between the connecting base plate 21 and the retaining seat 23, and the connecting base plate 21 can be fixed to the rotating assembly 10. All of the aforementioned components can be arranged along the axial direction.

[0048] The chute body 22 may have a guide groove 221 on at least one side in the axial direction. The guide groove 221 may be arranged along the first direction and / or the second direction. If the chute body 22 has a guide groove 221 on only one side, the guide groove 221 may be arranged along the first direction or the second direction. The specific arrangement direction of the guide groove 221 in the radial direction may be set according to the actual situation.

[0049] Each guide groove 221 may have a retaining plate 24 on both sides in the radial direction. The two retaining plates 24 can be connected by a return spring 25 so that they can respectively abut against both sides of the guide groove 221. The retaining plates 24 can be fixed to the connecting base plate 21 and / or the retaining seat 23. Specifically, if the guide groove 221 is located on the side of the slide body 22 close to the connecting base plate 21, then the retaining plates 24 on both sides of the guide groove 221 can be fixedly connected to the connecting base plate 21; if the guide groove 221 is located on the side of the slide body 22 close to the retaining seat 23, then the retaining plates 24 on both sides of the guide groove 221 can be fixedly connected to the retaining seat 23.

[0050] Understandably, the working principle of the slide adjustment assembly 20 is roughly as follows:

[0051] When the rotating assembly 10 is stationary, the clamping plate 24 is not pulled by external force, and the return spring 25 can make the two clamping plates 24 corresponding to each guide groove 221 in a mirror position, that is, the initial position.

[0052] When the rotating assembly 10 rotates and there is an eccentricity between the knob 13 or key and the rotating assembly 10, and the locking plate 24 is pulled by an external force that exceeds the tension of the return spring 25, the two locking plates 24 corresponding to each guide groove 221 are offset in opposite directions along the guide groove 221 to adjust the eccentricity of the rotating assembly 10 in the first or second direction, that is, to adjust and reduce the eccentricity between the knob 13 or key and the rotating assembly 10.

[0053] In some embodiments, such as Figure 4 As shown, the slide body 22 can have guide grooves 221 on both sides in the axial direction. The two guide grooves 221 can be set along the first direction and the second direction respectively, so that the slide adjustment assembly 20 can adjust the eccentricity of the rotating assembly 10 in two directions in the radial direction.

[0054] Along the axial direction, the clamping plate 24 located on the side of the slide body 22 near the connecting base plate 21 can be fixed to the connecting base plate 21, and the clamping plate 24 located on the side of the slide body 22 near the clamping seat 23 can be fixed to the clamping seat 23.

[0055] In some embodiments, such as Figure 4 As shown, when guide grooves 221 are provided on both sides of the slide body 22, the two guide grooves 221 can be arranged perpendicularly to each other in the radial direction, so that the slide body 22 forms a cross slide structure, so as to better adjust the eccentricity of the rotating component 10 in each direction in the radial direction.

[0056] In some embodiments, such as Figure 4 As shown, along the axial direction, the width of the guide groove 221 can gradually increase in the direction away from the slide body 22. The corresponding clamping plate 24 of the guide groove 221 can have an inclined surface on the side facing the guide groove 221 that can cooperate with the guide groove 221, so that the clamping plate 24 will not come out from the slide body 22 in the axial direction, thereby increasing the stability of the cooperation between the clamping plate 24 and the slide body 22.

[0057] In some embodiments, such as Figure 4 As shown, a clearance groove 222 may be provided on the guide groove 221, specifically located in the middle of the guide groove 221. Each of the two clamping plates 24 corresponding to the guide groove 221 can have a clearance portion 241 on one side facing the guide groove 221. The clearance groove 222 can communicate with the two clearance portions 241 to form a clearance space for placing the return spring 25. Each clearance portion 241 can have a positioning post 242. The two ends of the return spring 25 can be respectively sleeved on the positioning posts 242 in the two clearance portions 241, so that the two clamping plates 24 can be connected through the return spring 25.

[0058] In some embodiments, as one implementation of the rotating component 10, such as Figure 2 and Figure 3 As shown, the rotating assembly 10 includes a bushing 11, a insert shaft 12, and a knob 13. The bushing 11 can be fixed to the connecting base plate 21, and the insert shaft 12 can be inserted into the bushing 11 and fixed to the knob 13. When the knob 13 is rotated, it can drive the connecting base plate 21 to rotate through the bushing 11 and the insert shaft 12. The rotation of the connecting base plate 21 can drive each clamping plate 24 to move along the corresponding guide groove 221.

[0059] In some embodiments, such as Figure 3 As shown, the insert shaft 12 can be a square shaft or a polygonal shaft, so that when the insert shaft 12 rotates with the knob 13, the insert shaft 12 can drive the bushing 11 to rotate, and can effectively avoid slippage.

[0060] In some embodiments, as another implementation of the rotating component 10, the rotating component 10 may have a keyhole structure, which can be used to rotate the rotating component 10 by inserting a key into the keyhole structure and then rotating the key.

[0061] Based on the aforementioned chuck mechanism 100, such as Figure 1 As shown in the figure, this utility model embodiment also provides a smart door lock 200. The smart door lock 200 includes a door lock body 30 and the aforementioned clamping mechanism 100.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
