[0039] Reference below Figure 1-Figure 5 The smart lock mechanism according to an embodiment of the present invention is described.

[0040] like Figure 1-Figure 5As shown, the smart lock mechanism can be used in conjunction with a password keypad or mobile phone app to achieve multiple unlocking methods, including but not limited to mobile phone unlocking, password keypad close-range unlocking, and unlocking through the lock body structure. The unlocking methods of the smart lock mechanism are not detailed in this utility model. It should be understood that all unlocking methods are within the scope of protection defined by this utility model without departing from the basic concept of this utility model.

[0041] The smart lock mechanism includes a smart lock body 100. The surface of the smart lock body 100 near the door lock is provided with a mounting surface 101. A locking claw structure 110 is provided on the same side of the mounting surface 101. The smart lock body 100 is fixed to the door via the mounting surface 101 and connected to the door lock knob on the door via the locking claw structure 110. The locking claw structure 110 cooperates with the door lock knob to rotate. The locking claw structure 110 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0042] The smart lock body 100 is also provided with a drive structure 160, which is disposed within the smart lock body 100 and is in transmission connection with the pawl structure 110. The drive structure 160 is used to drive the pawl structure 110 to rotate, thereby rotating the door lock knob to unlock or close the door. The drive structure 160 drives the pawl structure 110 to rotate after receiving an electrical signal.

[0043] A rechargeable battery 210 and a backup battery 220 are respectively provided in the smart lock body 100 to power the smart lock body 100. The rechargeable battery 210 and the backup battery 220 are respectively detachably installed in the smart lock body 100, and the rechargeable battery 210 and the backup battery 220 are respectively electrically connected to the driving structure 160.

[0044] In some embodiments of the present invention, the smart lock body 100 is provided with a battery detection module (not shown in the drawings), which is electrically connected to the rechargeable battery 210 and the backup battery 220 and is used to detect the voltage or power of the rechargeable battery 210 and the backup battery 220. When the rechargeable battery 210 is separated from the smart lock body 100, or when the voltage or power of the rechargeable battery 210 is lower than a specified value, the backup battery 220 replaces the rechargeable battery 210 to power the drive structure 160.

[0045] Exemplarily, the rechargeable battery 210 is a lithium battery, and the backup battery 220 is a dry cell battery.

[0046] Specifically, if the voltage of the rechargeable battery 210 is normal, the rechargeable battery 210 is used first. When the battery detection module detects that the voltage of the rechargeable battery 210 is low, that is, when the battery capacity of the rechargeable battery 210 is reduced and insufficient to support the normal operation of all functions of the smart lock mechanism, or when the voltage of the rechargeable battery 210 is detected to be zero, that is, when the rechargeable battery 210 is separated from the smart lock body 100, and the battery detection module detects that the power of the backup battery 220 is not zero, the backup battery 220 will take over the power supply of the smart lock body 100. At this time, the user can remove the rechargeable battery 210 from the smart lock body to charge the rechargeable battery 210. During the period when the rechargeable battery 210 is removed, the backup battery 220 can maintain the normal use of the smart lock mechanism, and the user can still control the lock claw structure 110 through the mobile phone to unlock or close the lock, while the manual press unlock function and the password keypad of the smart lock body 100 cannot be used, thereby reminding the user to replace the rechargeable battery 210 or charge it. It effectively avoids the risk of the smart lock mechanism not being able to work normally due to low battery, and improves the user experience.

[0047] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the smart lock body 100 is provided with a spare storage slot 120, into which the spare battery 220 is removably installed. Specifically, the spare storage slot 120 is arranged in a circumferential shape, and can adopt a circular, prismatic, or flat groove shape. The shape of the spare storage slot 120 is adaptively adjusted according to the cell specifications of the spare battery 220.

[0048] Furthermore, the first opening of the spare accommodating slot 120 is provided on the other side opposite to the mounting surface 101, making it easy for the user to remove the spare battery 220. When the spare battery 220 is installed in the spare accommodating slot 120, the length direction of the spare battery 220 extends from the other side opposite to the mounting surface 101 toward the mounting surface 101.

[0049] When the backup battery 220 is installed in the backup receiving slot 120 , the length direction of the backup battery 220 extends from the other side opposite to the installation surface 101 toward the installation surface 101 , so that the backup battery 220 is not likely to fall out of the backup receiving slot 120 .

[0050] Furthermore, if Figure 1 and Figure 4As shown, the first opening of the spare accommodating groove 120 is provided with a cover plate 130, one end of the cover plate 130 is pivotally connected to one side of the first opening, and the other end is provided with a first connecting member. The smart lock body 100 is provided with a second connecting member. When the cover plate 130 is sealed on the first opening, the other end of the cover plate 130 is connected to the smart lock body 100 through the connection between the first connecting member and the second connecting member. For example, one of the first connecting member and the second connecting member can be a buckle, and the other can be a slot.

[0051] Furthermore, if Figure 1 and Figure 4 As shown, the first connecting member is a first fastening hole 131, and the second connecting member is a second fastening hole 132. The other end of the cover plate 130 passes through the first fastening hole 131 and the second fastening hole 132 through the fasteners, thereby connecting to the smart lock body 100. This further improves the installation stability of the backup battery 220 and effectively prevents the backup battery 220 from detaching.

[0052] Furthermore, if Figure 3-Figure 5 As shown, a first conductive member 171 is provided on the side of the cover plate 130 opposite the first opening, and a second conductive member (not shown in the drawings) is provided on the bottom wall of the backup accommodating groove 120. The two ends of the backup battery 220 are electrically connected to the first conductive member 171 and the second conductive member, respectively, to provide power to the driving structure 160. Specifically, one of the first conductive member 171 and the second conductive member is a metal sheet, and the other is a metal spring.

[0053] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, a body accommodating groove 140 is provided inside the smart lock body 100, and the second opening of the body accommodating groove 140 is provided on the other side opposite to the mounting surface 101. The smart lock body 100 also includes a panel 150, which is used to cover the second opening. The second opening is arranged adjacent to the first opening, and the rechargeable battery 210 can be removably installed in the body accommodating groove 140.

[0054] In this embodiment, the main body compartment 140 and the backup compartment 120 open in the same direction and are both concealed beneath a panel 150. The panel 150 is connected to the smart lock body 100 via a snap-fit ​​mechanism. When the panel 150 is removed, the rechargeable battery 210 is exposed, while the backup battery 220 is concealed by the cover 130 to prevent it from coming loose. Users can remove the rechargeable battery 210 independently without affecting the normal operation of the smart lock mechanism.

[0055] In some embodiments of the present invention, Figure 3-Figure 5As shown, the smart lock body 100 is provided with a receiving groove 103, and the third opening of the receiving groove 103 is provided on the inner side wall of the body receiving groove 140. A limit member 230 and an elastic return member 240 are provided in the receiving groove 103. One end of the elastic return member 240 is connected to the bottom wall of the receiving groove 103, and the other end of the elastic return member 240 is connected to or abuts against the limit member 230.

[0056] The receiving groove 103 is provided with a notch 104 on the other side opposite to or adjacent to the mounting surface 101 . The limiting member 230 has a toggle portion 231 . The toggle portion 231 extends toward the notch 104 and is exposed in the notch 104 .

[0057] The rechargeable battery 210 is provided with a limiting portion 211. When there is no external force or the external force disappears, the limiting member 230 extends from the third opening due to the elastic potential energy of the elastic return member 240 and cooperates with the limiting portion 211 to limit the rechargeable battery 210. When an external force pushes the toggle portion 231 away from the rechargeable battery 210, the elastic return member 240 contracts, and the limiting member 230 retracts to release the limit on the rechargeable battery 210. The limiting portion 211 may be a limiting groove, and the limiting member 230 extends from the third opening into the limiting groove due to the elastic potential energy of the elastic return member 240 to limit the rechargeable battery 210.

[0058] In this embodiment, the rechargeable battery 210 is limited by the cooperation between the limiting member 230 and the limiting portion 211, so that the rechargeable battery 210 can be stably installed in the main body accommodating groove 140. The toggle portion 231 on the limiting member 230 can conveniently release the limit on the rechargeable battery 210, so that the user can remove the rechargeable battery 210 from the smart lock body.

[0059] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the surface of the rechargeable battery 210 is provided with a handle structure 212 for achieving removal. Optionally, the surface of the rechargeable battery 210 is pivotally connected to a pull ring structure for achieving removal. Specifically, when the rechargeable battery 210 needs to be removed from the smart lock body 100, the user manually flips the pull ring structure to form a handle and then pinches the pull ring structure to pull the rechargeable battery 210 out of the body accommodating slot 140.

[0060] Optionally, the handle structure 212 is made of a flexible material.

[0061] In some embodiments of the present invention, the capacity of the rechargeable battery 210 is greater than that of the backup battery 220. Specifically, the rechargeable battery 210, which serves as the primary power source, has a larger battery capacity. The backup battery 220, which is only used for short-term power supply, has a smaller capacity than the rechargeable battery 210. This helps reduce the space occupied by the backup battery 220 within the smart lock body 100.

[0062] In some embodiments of the present invention, Figure 2 As shown, the smart lock body 100 is provided with a mounting groove 102 on the same side as the mounting surface 101. The locking claw structure 110 is disposed in the mounting groove 102. When the mounting surface 101 is in contact with the surface of the door, the locking claw structure 110 in the mounting groove 102 clamps the door lock knob on the door. Specifically, the locking claw structure 110 is immersed in the mounting groove 102. When the mounting surface 101 of the smart lock body 100 is in contact with the surface of the door, the door lock knob is located in the mounting groove 102 and cooperates with the locking claw structure 110, making the smart lock body 100 and the door lock fit more closely.

[0063] It should be understood that completely submerging the locking claw structure 110 within the mounting slot 102 is not the only embodiment. In some other embodiments, the locking claw structure 110 can protrude a certain distance from the end surface of the mounting slot 102 to accommodate certain special door lock knob models. The present invention does not elaborate on the assembly positions of the locking claw structure 110 and the mounting slot 102. It should be understood that flexible changes in the assembly positions of the locking claw structure 110 and the mounting slot 102 without departing from the basic concept of the present invention should be considered within the scope of protection defined by the present invention.
