Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a smart lock with a deadbolt structure. Background Technology

[0002] As people's living standards improve, the demand for private space is also increasing. In addition to traditional smart locks for main doors, smart locks can also be installed on interior doors such as bedrooms and studies to improve the privacy of these rooms.

[0003] Most existing indoor smart locks use spherical locks, which avoid the bulkiness of traditional smart locks and are more suitable for indoor use. Most existing spherical smart locks are single-tongue fingerprint locks. These spherical smart locks can be unlocked by password or fingerprint. In terms of privacy, they can only isolate users who do not know the password. For people who know the password or other members with administrator status, they can still prevent them from entering the room by entering the password. Privacy needs to be improved, so improvements are required. Utility Model Content

[0004] The main purpose of this invention is to propose a smart lock with a deadbolt structure, aiming to provide a smart lock with a high degree of privacy.

[0005] To achieve the above objectives, this utility model proposes an intelligent lock with a deadbolt structure, comprising a lock body, which includes a first locking part and a second locking part. The first locking part is installed on the outside of the outer door body, and the second locking part is installed on the inside of the outer door body. A drive shaft is provided between the first locking part and the second locking part. A door lock rotation angle is provided on the second locking part. The drive shaft is connected to the door lock rotation angle. A locking device is also provided on the second locking part for locking the door lock rotation angle.

[0006] Specifically, the locking device includes a latch and a control handle. The control handle and the latch are connected by a transmission. The control handle engages the door lock by moving the latch.

[0007] Specifically, the door lock has a locking part on its rotation angle and a locking hole on its latch. The control handle drives the latch to engage or disengage with the locking part on the door lock's rotation angle through the locking hole.

[0008] Specifically, the second locking part is provided with a mounting groove, the snap fastener is located in the mounting groove, and a return spring is directly provided between the snap fastener and the mounting groove, with the spring abutting against the snap fastener and the mounting groove respectively.

[0009] Specifically, the snap-fit ​​is arc-shaped.

[0010] This utility model's technical solution involves setting a door lock rotation angle on the second locking part, in conjunction with a locking device, to lock or unlock the door lock rotation angle, thereby achieving physical deadlock of the smart lock. When the physical deadlock is not unlocked, it can effectively prevent other members with administrator status from unlocking the smart lock with a password, thus improving the privacy of the smart lock.

[0015] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0016] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0017] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0018] like Figures 1 to 3 As shown, a smart lock with a deadbolt structure includes a lock body, which includes a first locking part 10 and a second locking part 20. The first locking part 10 is installed on the outside of the outer door body, and the second locking part 20 is installed on the inside of the outer door body. A drive shaft 30 is provided between the first locking part 10 and the second locking part 20. A door lock rotation angle 23 is provided on the second locking part 20. The drive shaft 30 is connected to the door lock rotation angle 23. A locking device is also provided on the second locking part 20 to lock the door lock rotation angle 23. When installing the smart lock, the first locking part 10 and the second locking part 20 are first installed on the outside and inside of the door respectively. When the door is opened normally, the correct password is entered or the administrator's fingerprint is placed on the first locking part 10 for identification, thereby unlocking the first locking part 10. By rotating the first locking part 10, the drive shaft 30 is rotated, which in turn rotates the door lock rotation angle 23 and finally unlocks the bolt 40, thus opening the door. When someone is inside, the locking device located on the second locking part 20 locks the door lock rotation angle 23, thereby locking the drive shaft 30, so that the first locking part 10 cannot be rotated even when it is unlocked, thereby improving the privacy of the smart lock.

[0019] The locking device includes a latch 21 and a control handle 22. The control handle 22 and the latch 21 are connected by a transmission. The control handle 22 engages the door lock rotation angle 23 by moving the latch 21. In this embodiment, pulling the control handle 22 engages the latch 21 with the door lock rotation angle 23, thereby locking the door lock rotation angle 23; pushing the control handle 22 unlocks and resets the latch 21 and the door lock rotation angle 23.

[0020] The door lock rotation angle 23 is provided with a locking part, and the latch 21 is provided with a locking hole. The control handle 22 drives the latch 21 to engage or disengage with the locking part provided on the door lock rotation angle 23 through the locking hole. In this embodiment, the latch 21 is provided with a locking hole, and the latch 21 cooperates with the locking part provided on the door lock rotation angle 23 through the locking hole to achieve locking of the door lock rotation angle 23.

[0021] The second locking part 20 is provided with a mounting groove 24, and the snap-fit ​​buckle 21 is located in the mounting groove 24. A return spring 25 is directly provided between the snap-fit ​​buckle 21 and the mounting groove 24, and the spring abuts against the snap-fit ​​buckle 21 and the mounting groove 24 respectively. In this embodiment, the return spring 25 is provided to improve the reset effect when the snap-fit ​​buckle 21 is unlocked, thereby improving the unlocking efficiency.

[0022] The snap-fit ​​21 is arc-shaped. In this embodiment, the snap-fit ​​21 is arc-shaped, which facilitates structural fitting with the ball lock and improves the installation efficiency of the snap-fit ​​21.

[0023] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
