[0028] Please refer to Figures 1-5 An embodiment of this utility model provides a multi-functional intelligent access lock, which includes: a front handle 11, a front body 10, a rear handle 21, a rear body 20, an unlocking shaft 30, a clutch pin 13, a drive source 14, a first circuit board 18, and a lock cylinder 15. The front handle 11 is located at the front end of the front body 10, and the rear body 20 is located at the rear end of the rear handle 21. One end of the unlocking shaft 30 is connected to the front handle 11, and the other end of the unlocking shaft 30 is connected to the rear handle 21. By rotating the front handle 11 and the rear handle 21, the unlocking shaft 30 can be rotated to unlock the door. The clutch sleeve 12 is located on the end of the unlocking shaft 30 connected to the front handle 11. The clutch pin 13 is located in the front body 10 and is used to extend into the clutch sleeve 12 to restrict the rotation of the unlocking shaft 30. The drive source 14 is located in the front body 10 and is used to drive the clutch pin 13 to disengage from the clutch sleeve 12 to release the rotation restriction on the unlocking shaft 30. The first circuit board 18 is located in the front body 10 and is electrically connected to the drive source 14. When the power supply is sufficient, the drive source 14 can drive the clutch pin 13 to disengage from the clutch sleeve 12 to release the rotation restriction on the unlocking shaft 30.
[0029] To prevent the clutch pin 13 from being unable to be driven by the drive source 14 when there is no power, the front body 10 is specially equipped with a lock cylinder 15 that is linked to the clutch pin 13, providing an additional unlocking method. Users can drive the clutch pin 13 to move by inserting the key into the lock cylinder 15 and turning it, so that the product can be easily unlocked even when there is no power.
[0030] In a preferred embodiment, the front body 10 is further provided with a meshing gear and rack (not shown in the figure). The axial direction of the lock cylinder 15 is parallel to the axial direction of the unlocking shaft 30. The lock cylinder 15 includes an insertion end 151 and a linkage end 152 arranged opposite to each other. The insertion end 151 is used to insert a key. The gear is sleeved on the linkage end 152. The clutch pin 13 is connected to the rack. When the lock cylinder 15 rotates, it can drive the gear to rotate, thereby driving the rack and clutch pin 13 to move, so as to release the rotation restriction on the unlocking shaft 30.
[0031] In a preferred embodiment, reference may be made to Figure 2 and Figure 3The front body 10 is also provided with a linkage component 16. The lock cylinder 15 includes an insertion end 151 and a linkage end 152 that are arranged opposite to each other. One end of the linkage component 16 is linked with the linkage end 152 of the lock cylinder 15, and the other end is linked with the clutch pin 13. When the lock cylinder 15 rotates, it drives the linkage component 16 to rotate, so as to drive the clutch pin 13 to disengage from the clutch sleeve 12.
[0032] Specifically, the front body 10 also includes a locking sleeve 17, with a lock cylinder 15 threadedly connected to the inner circumference of the locking sleeve 17. The linkage 16 rotates around the axial direction of the unlocking shaft 30, and the axial direction of the lock cylinder 15 is perpendicular to the axial direction of the unlocking shaft 30. In this embodiment, when the lock cylinder 15 rotates, it can move up and down relative to the locking sleeve 17, thereby driving the linkage 16 to rotate, so that the clutch pin 13 moves up and down, thereby disengaging from or extending into the clutch sleeve 12.
[0033] Preferably, the bottom of the drive source 14 is also provided with a mounting plate 19, and the clutch pin 13 is vertically connected to the mounting plate 19. The drive source 14 drives the mounting plate 19 to move so as to cause the clutch pin 13 to disengage from the clutch sleeve 12. When the linkage 16 rotates, it can drive the mounting plate 19 to move, thereby causing the clutch pin 13 to disengage from the clutch sleeve 12.
[0034] In a preferred embodiment, to facilitate key insertion by the user and to enhance the concealment of the lock cylinder 15 and the security of the smart lock, the insertion end 151 is positioned downwards at the bottom of the front body 10.
[0035] In a preferred embodiment, in order to enable the front handlebar 11 and the rear handlebar 21 to automatically reset when no force is applied, a torsion spring (not shown) is fitted on both the front handlebar 11 and the rear handlebar 21.
[0036] In a preferred embodiment, to avoid the inability to unlock the clutch pin 13 by driving the drive source 14 in the event of an emergency power outage or when the battery is depleted, refer to... Figure 2 and Figure 3 The bottom of the front body 10 is provided with a charging interface 50, which is electrically connected to the first circuit board 18.
[0037] In a preferred embodiment, reference may be made to Figure 1 and Figure 2 The front handle 11 is equipped with a fingerprint reader 41, which is electrically connected to the first circuit board 18. The fingerprint reader 41 is used for fingerprint recognition. After the fingerprint recognition is successful, the clutch pin 13 can be driven by the drive source 14 to disengage from the clutch sleeve 12, thereby releasing the rotation restriction on the unlocking shaft 30.
[0038] In a preferred embodiment, reference may be made to Figure 2 and Figure 3The front body 10 is equipped with a camera 42, a speaker 43, a microphone 44 and a doorbell 45. The camera 42, speaker 43, microphone 44 and doorbell 45 are all electrically connected to the first circuit board 18.
[0039] In this embodiment, a visitor can press the doorbell 45 and communicate visually with the user via the camera 42, speaker 43, and microphone 44, allowing the user to learn about the visitor. Then, the user can control the drive source 14 via a mobile app to disengage the clutch pin 13 from the clutch sleeve 12, thereby releasing the rotation restriction on the unlocking shaft 30. Alternatively, visitor information can be determined through facial recognition. After successful facial recognition, the system can automatically drive the drive source 14 to disengage the clutch pin 13 from the clutch sleeve 12, thus releasing the rotation restriction on the unlocking shaft 30.
[0040] In a preferred embodiment, the front body 10 is further provided with a password button 46 on the side opposite to the rear body 20, and the password button 46 is electrically connected to the first circuit board 18. In this embodiment, a visitor or user who knows the password can enter the password by pressing the password button 46, thereby driving the clutch pin 13 to disengage from the clutch sleeve 12, thus releasing the rotation restriction on the unlocking shaft 30.
[0041] In a preferred embodiment, reference may be made to Figure 4 and Figure 5 The rear body 20 includes a main shell 22 and a sliding cover 23, with a battery cavity 24 located between the main shell 22 and the sliding cover 23. The multi-functional smart access lock also includes a battery box (not shown), which is used to hold dry batteries. The battery box and the battery cavity 24 are detachably connected. When the battery box is removed from the battery cavity 24, the battery cavity 24 can be used to hold lithium batteries.
