[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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 some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] When a smart lock runs out of power or malfunctions, a reliable emergency unlocking mechanism is needed, namely, retaining the traditional mechanical key unlocking method. Although the existence of the mechanical key provides a solution for emergencies, it also brings new troubles to users: on the one hand, if users choose to carry the mechanical key with them, it will greatly reduce the convenience of using the smart lock; on the other hand, if they do not carry the mechanical key, they will not be able to unlock the smart lock when it runs out of power or malfunctions.

[0037] To address or improve the convenience of smart locks caused by carrying mechanical keys, and the inability to unlock them in the event of power failure or malfunction without carrying a mechanical key, this utility model provides a lock body and a smart lock.

[0038] The following is combined Figures 1 to 5 The following describes the lock body 1 provided in the embodiments of this utility model.

[0039] Lock body 1 is suitable for smart locks. It is understood that smart locks typically include a front lock body and a rear lock body; in this embodiment, lock body 1 refers to the front lock body, i.e., the lock body located on the outside of the door. Of course, it is not excluded that in some situations, the lock body 1 provided in this embodiment can be applied to the inside of the door.

[0040] Specifically, the lock body 1 provided in this embodiment includes a main body 101, a mechanical key 102, and a mechanical combination lock 103.

[0041] The main body 101 is equipped with an emergency lock cylinder. The emergency lock cylinder is connected to the lock cylinder of the smart lock and is used to drive the lock cylinder of the smart lock to rotate and unlock. Optionally, the main body 101 can be a housing structure; for example, the interior of the main body 101 can be used to house the emergency lock cylinder and circuit boards, among other components. Optionally, the main body 101 is provided with a mechanical keyhole, which is positioned opposite to the emergency lock cylinder and allows a mechanical key 102 to pass through.

[0042] The mechanical key 102 is matched with the emergency lock cylinder, that is, the mechanical key 102 can be inserted into the emergency lock cylinder and can drive the emergency lock cylinder to rotate, thereby driving the lock cylinder of the smart lock to rotate and unlock.

[0043] The mechanical combination lock 103 is used to lock the mechanical key 102 onto the main body 101 or to unlock the mechanical key 102 from the main body 101. Specifically, the mechanical combination lock 103 can be unlocked after the correct combination is entered into it. If an incorrect combination is entered into the mechanical combination lock 103, the mechanical combination lock 103 will remain locked. Optionally, the mechanical combination lock 103 may include, but is not limited to, a rotary combination lock and a push-button combination lock.

[0044] In this embodiment, under normal circumstances, the mechanical key 102 is locked to the main body 101 by the mechanical combination lock 103 and cannot be removed and inserted into the mechanical keyhole. In the event of a power outage or malfunction of the smart lock, the correct password can be entered into the mechanical combination lock 103 to unlock it, allowing the mechanical key 102 to be removed and inserted into the mechanical keyhole to unlock the smart lock.

[0045] With this design, since the mechanical key 102 is locked to the main body 101, the smart lock can be unlocked by removing the mechanical key 102 from the mechanical combination lock 103 even without carrying the key, avoiding the problem of being unable to unlock the lock in special circumstances if the mechanical key 102 is forgotten. At the same time, the user does not need to carry the mechanical key 102, thus avoiding any impact on the convenience of the smart lock.

[0046] In addition, the mechanical combination lock 103 can be used to protect the mechanical key 102 and prevent unauthorized personnel from using the mechanical key 102 to unlock the smart lock.

[0047] In some embodiments of this utility model, the main body 101 is further provided with a receiving cavity 1011. Optionally, the receiving cavity 1011 is disposed on the surface of the main body 101 and recessed into the interior of the main body 101. Optionally, the main body 101 is configured as a shell structure, and the receiving cavity 1011 communicates with the inner cavity of the main body 101.

[0048] The mechanical key 102 is detachably disposed within the receiving cavity 1011, meaning that the mechanical key 102 can be installed in the receiving cavity 1011 or removed from the receiving cavity 1011. Optionally, at least a portion of the mechanical key 102 is disposed within the receiving cavity 1011, meaning that a portion of the mechanical key 102 is disposed within the receiving cavity 1011 or the mechanical key 102 is completely disposed within the receiving cavity 1011.

[0049] In this embodiment, by providing a receiving cavity 1011 on the main body 101 and placing the mechanical key 102 in the receiving cavity 1011, the internal space of the main body 101 can be fully utilized, the size of the mechanical key 102 protruding from the outer surface of the main body 101 can be reduced, and the structure of the lock body 1 can be made more compact.

[0050] On the other hand, it makes the mechanical key 102 relatively concealed, reducing the risk of the mechanical key 102 being easily discovered and illegally used, and increasing the protective capability of the lock body 1.

[0051] In some embodiments provided by this utility model, the lock body 1 also includes a cover 104.

[0052] The cover 104 is used to open and close the receiving cavity 1011. The mechanical combination lock 103 is provided on the main body 101 or the cover 104. The mechanical combination lock 103 is used to lock the cover 104 to the main body 101 or to unlock it from the main body 101.

[0053] In this embodiment, the cover 104 can close the receiving cavity 1011, and the mechanical combination lock 103 can lock the cover 104 to the main body 101. That is, the mechanical combination lock 103 locks the mechanical key 102 in the receiving cavity 1011 by locking the cover 104.

[0054] Similarly, the cover 104 is unlocked by the mechanical combination lock 103 so that the cover 104 can open the receiving cavity 1011. That is, the mechanical combination lock 103 unlocks the mechanical key 102 from the receiving cavity 1011 by unlocking the cover 104.

[0055] This design, by sealing the receiving cavity 1011 with the cover 104, further increases the concealment of the mechanical key 102, reduces the possibility that unauthorized persons can easily discover and use the mechanical key 102, and reduces potential security risks.

[0056] In addition, the cover 104 can protect the mechanical key 102 from dust, moisture and other contaminants, extending the service life of the mechanical key 102.

[0057] In addition, the design of the cover 104 can make the lock body 1 look cleaner, help reduce unnecessary protrusions or protrusions on the outside of the lock body 1, make the lock body 1 more compact, suitable for more installation scenarios, and avoid the visual clutter caused by the exposed mechanical key 102.

[0058] In some embodiments provided by this utility model, a flange 1044 is provided on the cover 104, a part of the cover 104 is placed in the receiving cavity 1011, and the flange 1044 is provided on the part of the cover outside the receiving cavity 1011. The flange 1044 abuts against the outer wall of the main body 101 to limit the cover 104 and make the cover 104 have an accurate installation position.

[0059] In some embodiments provided by this utility model, the mechanical combination lock 103 includes a bolt and a set of turntables. Each turntable has a specific notch. When each turntable is rotated to correspond to the correct password, the notches of each turntable are aligned. At this time, the bolt can move to complete the unlocking.

[0060] It is understood that the mechanical combination lock 103 is a product of the prior art, and this application does not involve any improvement to the mechanical combination lock 103, so it will not be described in detail here.

[0061] In some embodiments of this utility model, a mechanical combination lock 103 is mounted on the main body 101. Specifically, a set of turntables and a latch are both mounted on the main body 101, and a cover 104 is provided with a locking portion that engages with the latch of the mechanical combination lock 103. When the latch is engaged with the locking portion, the cover 104 cannot be opened. When the correct combination is entered into the mechanical combination lock 103, the latch can move, thereby disengaging from the locking portion and unlocking the cover 104.

[0062] Alternatively, the turntable and the latch are not limited to both being located on the main body 101. For example, in other embodiments, a set of turntables is located on the main body 101, and the latch is located on the cover 104. When the correct combination is entered into the mechanical combination lock 103, the latch can disengage from the turntables, thereby unlocking the cover 104.

[0063] Of course, the mechanical combination lock 103 is not limited to being installed on the main body 101; for example, see reference. Figure 2 and Figure 3 As shown, in some other embodiments provided by this utility model, the mechanical combination lock 103 is provided on the cover 104.

[0064] Specifically, the latch and a set of turntables are both mounted on the cover 104, and the main body 101 has a locking part that engages with the latch. When the latch is engaged with the locking part, the cover 104 cannot be opened. When the correct password is entered into the mechanical combination lock 103, the latch can move, thereby disengaging from the locking part and unlocking the cover 104.

[0065] Alternatively, the turntable and the latch are not limited to both being located on the cover 104. For example, in other embodiments, a set of turntables is located on the cover 104, and the latch is located on the body 101. When the correct combination is entered into the mechanical combination lock 103, the latch can disengage from the turntables, thereby unlocking the cover 104.

[0066] In some embodiments provided by this utility model, the mechanical key 102 is detachably connected to the surface of the cover 104 facing the receiving cavity 1011.

[0067] In this embodiment, by connecting the mechanical key 102 to the surface of the cover 104 facing the receiving cavity 1011, the mechanical key 102 can be removed from the receiving cavity 1011 at the same time as the cover 104 is opened. This allows the user to easily access the mechanical key 102 and reduces the steps required to retrieve the mechanical key 102, which can significantly improve the efficiency of the unlocking process. This is especially important in situations that require a rapid response, such as emergency evacuation and rapid entry scenarios.

[0068] refer to Figure 5 As shown, in some embodiments provided by this utility model, the mechanical key 102 is snapped into connection with the cover 104.

[0069] In this embodiment, a snap-fit ​​connection is used, allowing the user to quickly and easily remove the mechanical key 102 from the cover 104 when needed. Snap-fit ​​connections typically require no additional tools or complex steps for assembly, simplifying the manufacturing process and facilitating subsequent maintenance or replacement. Because snap-fit ​​is a relatively simple and economical connection method, it helps reduce production costs without affecting product performance or user experience.

[0070] refer to Figure 5 As shown, optionally, the cover 104 is provided with a slot 1041 into which a mechanical key 102 can be inserted. The depth direction of the slot 1041 is consistent with the opening direction of the receiving cavity 1011. The inner wall of the slot 1041 is provided with a locking protrusion 1042, which is used to limit the mechanical key 102 in the depth direction of the slot 1041.

[0071] Optionally, both ends of the mechanical key 102 are respectively placed into the corresponding slots 1041 so that the mechanical key 102 is subjected to balanced force at both ends, thereby providing a better positioning effect for the mechanical key 102 by the slots 1041.

[0072] refer to Figure 5 As shown, optionally, a through groove 1043 is provided on at least one side of the snap-fit ​​protrusion 1042, and the through groove 1043 penetrates the side wall of the snap groove 1041 along the wall thickness direction. In this embodiment, by providing a through groove 1043 on at least one side of the snap-fit ​​protrusion 1042, the structural rigidity of the snap groove 1041 is reduced, making the part where the snap-fit ​​protrusion 1042 is located more prone to deformation, so as to facilitate inserting the key into or removing it from the snap groove 1041.

[0073] Of course, the mechanical key 102 is not limited to snapping with the cover 104. For example, in some embodiments not shown, the mechanical key 102 can also be magnetically connected to the cover 104.

[0074] In this embodiment, the magnetic connection allows the user to quickly and easily remove or install the mechanical key 102. Simply bring the mechanical key 102 close to the corresponding position on the cover 104, and the magnetic force will automatically guide and secure the mechanical key 102, without the need for complicated alignment operations.

[0075] When the mechanical key 102 and the cover 104 are magnetically attracted, the user can clearly feel the attraction action completed. This instant tactile feedback lets the user know that the operation has been successfully completed without the need for repeated confirmation.

[0076] Magnetic connections can usually tolerate a certain degree of positional deviation, which means that users can operate smoothly even under less than ideal conditions (such as poor lighting or limited space).

[0077] Optionally, a magnet may be provided on the cover 104 to attract the iron-containing mechanical key 102.

[0078] Alternatively, a magnetic attraction assembly can be provided between the mechanical key 102 and the cover 104. The magnetic attraction assembly includes two sets of mutually attracting magnets, which are respectively disposed on the mechanical key 102 and the cover 104. Alternatively, the magnet assembly includes a magnet and an iron block, which are respectively disposed on the mechanical key 102 and the cover 104.

[0079] In some embodiments provided by this utility model, the lock body 1 further includes a push-button buckle, which includes a buckle head and a buckle base.

[0080] The latching base is disposed within the receiving cavity 1011, for example, the latching base is connected to the main body 101. The latching head is disposed at a position opposite to the latching base on the cover 104, that is, the latching head is connected to the cover 104. The latching head is configured to be able to engage or disengage with the latching base by pressing.

[0081] In this embodiment, a push-button latch is provided between the main body 101 and the cover 104. After the mechanical combination lock 103 is unlocked, the cover 104 can only be opened by pressing it. Thus, even if the mechanical combination lock 103 is unlocked, it is still necessary to know how to open the cover 104 by pressing it. This adds an extra layer of security and reduces the risk of unauthorized personnel easily opening the cover 104.

[0082] In addition, when the recess 1011 is located at the bottom of the smart lock, a push-button buckle is provided between the main body 101 and the cover 104 to prevent the cover 104 from opening or falling off under gravity after being unlocked in certain situations.

[0083] It is understood that the push-button buckle, also known as the spring lock or push-button latch, is a product of the prior art. This application does not involve any structural improvement of the push-button buckle itself, so it will not be described in detail here.

[0084] In some embodiments of this utility model, the mechanical key 102 is configured as a foldable structure. In this embodiment, by configuring the mechanical key 102 as a foldable structure, the space occupied by the mechanical key 102 in the receiving cavity 1011 is reduced, so that the volume of the receiving cavity 1011 can be smaller, and the space occupied by the receiving cavity 1011 in the lock body 1 is avoided.

[0085] Optionally, the mechanical key 102 includes at least two connecting segments, which are hinged to each other.

[0086] In some embodiments of this utility model, the cover 104 is rotatably connected to the main body 101, that is, the cover 104 can be rotatably opened to accommodate the recess 1011 or rotatably closed to accommodate the recess 1011. In this way, after the cover 104 is rotatably opened, it still remains connected to the main body 101, making the cover 104 less likely to be lost.

[0087] Of course, the cover 104 is not limited to being rotatably connected to the main body 101. For example, in other embodiments, the cover 104 is slidably connected to the main body 101, that is, the cover 104 can slide open to receive the recess 1011 or slide to close to receive the recess 1011. In this way, after the cover 104 is slid open, it still remains connected to the main body 101, making the cover 104 less likely to be lost.

[0088] Of course, the cover 104 is not limited to sliding connection with the body 101. For example, in other embodiments, the cover 104 is detachably connected to the body 101, that is, the cover 104 is connected to the body 101 through a mechanical combination lock 103. This arrangement eliminates the need for an additional connection structure between the cover 104 and the body 101, thereby making the structure of the lock body 1 simple, easy to process, and lower in cost.

[0089] In some embodiments provided by this utility model, the lock body 1 further includes a sealing element, which is disposed between the cover 104 and the body 101 and is used to seal the gap between the cover 104 and the body 101. The sealing element can be a sealing gasket or a sealing ring.

[0090] This design improves the sealing between the cover 104 and the main body 101, preventing moisture or impurities from entering the receiving cavity 1011 and affecting the mechanical key 102 or other components inside the lock body 1.

[0091] In some embodiments provided by this utility model, the lock body 1 further includes a first flexible member, which is connected to the cover 104 and the main body 101 respectively. The first flexible member can be a chain or a rope.

[0092] In this embodiment, the first flexible member is connected to the cover 104 and the main body 101 respectively. After the cover 104 is opened, the cover 104 is still connected to the main body 101 of the lock body 1 through the flexible member, which can avoid the problem of the cover 104 falling off or being lost.

[0093] In some embodiments provided by this utility model, the lock body 1 further includes a second flexible member, which is connected to the mechanical key 102 and the cover 104 or the main body 101 respectively. The second flexible member can be a chain or a rope.

[0094] In this embodiment, the second flexible member is connected to the mechanical key 102 and the cover 104 or the main body 101 respectively. The second flexible member can adapt to the position change of the mechanical key 102, so that the mechanical key 102 can be inserted into the mechanical key hole without affecting the unlocking process of the mechanical key 102. After the mechanical key 102 is removed, the mechanical key 102 is still connected to the main body 101 and the cover 104 through the flexible member, which can avoid the problem of the mechanical key 102 falling off or being lost.

[0095] In some embodiments provided by this utility model, a mechanical combination lock 103 is disposed on the main body 101 and is used to lock the mechanical key 102 onto the main body 101 or to unlock the mechanical key 102 from the main body 101. This arrangement can reduce the number of parts in the lock body 1, making the structure of the lock body 1 more compact.

[0096] Optionally, the mechanical combination lock 103 has a set of dials and a bolt both mounted on the main body 101, and the mechanical key 102 has a locking part that engages with the bolt of the mechanical combination lock 103. When the bolt is engaged with the locking part, the mechanical key 102 cannot be removed. When the correct combination is entered into the mechanical combination lock 103, the bolt can move, thereby disengaging from the locking part, and the mechanical key 102 can be removed.

[0097] Alternatively, the turntable and the latch are not limited to being both located on the main body 101. For example, in other embodiments, a set of turntables is located on the main body 101, and the mechanical key 102 serves as the latch of the mechanical combination lock 103. When the correct password is entered into the mechanical combination lock 103, the mechanical key 102 can be disengaged from the turntable, and thus the mechanical key 102 can be removed.

[0098] This utility model also provides a smart lock in its embodiments.

[0099] Specifically, the smart lock includes the lock body 1 as described above.

[0100] The lock body 1 is equipped with at least one of a biometric identification unit and a password input component.

[0101] In this embodiment, the smart lock includes a lock body 1, and thus includes all the advantages of the lock body 1 mentioned above.

[0102] Optionally, the biometric unit includes, but is not limited to, a fingerprint recognition device, a palm print recognition device, and an iris recognition device.

[0103] Optionally, the password input component includes, but is not limited to, a touchscreen and a keypad input device.

[0104] In some embodiments provided by this utility model, the mechanical combination lock 103 locks the mechanical key 102 to the bottom end face of the main body 101 in the vertical direction.

[0105] In this embodiment, placing the receiving cavity 1011 on the bottom end face of the lock body 1 means that it is not easily seen or noticed directly, increasing the concealment of the mechanical key 102 and its storage location. This makes it more difficult for unauthorized persons to find and attempt to access the mechanical key 102, thereby improving the overall level of security.

[0106] The bottom design makes the mechanical key 102 less susceptible to external environmental influences, such as rain and dust. This design can better protect the mechanical key 102 and extend its service life.

[0107] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
