DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-9 A smart spherical lock includes a front lock body 1 and a rear lock body 2. The front lock body 1 includes a front shell 11, a front middle shell 12, a front bottom shell 13, a fingerprint module 14, a lock core and a control component 16.

[0031] The rear lock body 2 includes a rear cover 21 , a rear middle shell 22 , a rear bottom shell 23 and a Hall switch 24 .

[0032] The front shell 11 is rotatably arranged on one side of the front middle shell 12, the fingerprint module 14 is arranged inside the front shell 11, a telescopic lock cylinder 15 and a lock cylinder shaft 17 at one end of the telescopic lock cylinder 15 are arranged inside the front middle shell 12, and the lock cylinder shaft 17 is square. One end of the front shell 11 extends to the interior of the front bottom shell 13, and the interior of the front bottom shell 13 is provided with a front lock rotating shaft 18 fixed to the front bottom shell 13 by a retaining spring. A square rod sleeve 19 is movably provided inside the front bottom shell 13, and a square rod 191 is fixedly provided inside the square rod sleeve 19. The square rod 191 extends to the interior of the rear bottom shell 23 away from one end of the square rod sleeve 19, and the interior of the rear bottom shell 23 is provided with a square rod groove 231 that is socketed with the square rod 191.

[0033] A pin 181 is provided inside the front lock rotating shaft 18 to be movable by a spring 182. The control component 16 includes a main board 161 provided inside the front shell 11 and a motor 162 provided inside the front bottom shell 13. A plastic sliding shaft 163 is provided at the output end of the motor 162.

[0034] Specifically, a circle of the square rod sleeve 19 is provided with a number of not less than one linkage groove 192, and one of the linkage grooves 192 is opposite to the pin 181. A touch port 111 corresponding to the fingerprint module 14 is provided on one side of the front shell 11, and a front shell 12 cover is also provided on one side of the front shell 12. The touch port 111 is used to expose the identification area of ​​the fingerprint module 14 to obtain fingerprint information. The main board 161 is fixed to the inside of the front shell 11 by screwing. When the fingerprint is unlocked, after the fingerprint information is verified, the output end of the motor 162 is connected to the screw threaded with the plastic slide shaft 163, and the motor 162 rotates the plastic When the sliding shaft 163 moves forward, the plastic sliding shaft 163 contacts the pin 181 and compresses the spring 182, causing the pin 181 to retract inward. The pin 181 is inserted into the linkage groove 192 and connected to the square rod sleeve 19. The square rod 191 is fixed in the square rod sleeve 19. At this time, the front lock body 1 is rotated to drive the square rod 191 to rotate the oblique bolt lock body 3 to unlock, so that the oblique bolt lock body 3 is separated from the door strike hole to achieve the purpose of unlocking. When closing the lock, the motor 162 reverses and moves the plastic sliding shaft 163 backward. Due to the force of the spring 182, the pin 181 extends outward and is separated from the square rod sleeve 19. At this time, the rotation of the front lock body 1 is idling and cannot be unlocked.

[0035] Specifically, one side of the front shell 11 is provided with an eccentric shaft 112 with one end extending to the interior of the front middle shell 12, and a tension spring 113 is sleeved on the eccentric shaft 112. Figure 3 and Figure 4One side of the front middle shell 12 is provided with a convex edge that is locked into the inside of the front shell 11. When rotating the front shell 11, it is necessary to pull the front shell 11 back a certain distance first, so that the front shell 11 compresses the tension spring 113 through the eccentric shaft 112. At the same time, the front shell 11 is disengaged from the engagement with the convex edge, and the front shell 11 can be rotated to expose the telescopic lock cylinder 15, which is convenient for the user to unlock with a key.

[0036] Specifically, a compression spring 171 is provided on the outer side of the lock core shaft 17 close to the telescopic lock core 15. When the key is used to unlock the door, the telescopic lock core 15 extends outward to push the lock core shaft 17 to move forward and connect with the square rod sleeve 19. The square rod 191 is fixed to the square rod sleeve 19. At this time, the front lock body 1 is rotated to drive the square rod 191 to rotate the oblique bolt to unlock the door, so that the oblique bolt is separated from the door buckle hole to achieve the purpose of unlocking. When the door is locked, the telescopic lock core 15 retracts inward, and the lock core shaft 17 moves backward due to the force of the spring 182 and separates from the square rod sleeve 19. At this time, the front lock body 1 is idle and cannot be unlocked.

[0037] Specifically, one end of the rear middle shell 22 passes through one side of the rear bottom shell 23, and the other end is provided with a rear cover 21. The interior of the rear bottom shell 23 is also provided with a rear lock rotating shaft 25 fixed to the rear middle shell 22 and the rear bottom shell 23 by a retaining spring. The interior of the rear bottom shell 23 is provided with a Hall switch 24, and a magnet 26 matching the Hall switch 24 is provided on the rear lock rotating shaft 25. One side of the rear bottom shell 23 is provided with a normally open button 27, a reset button 28 and an anti-lock button 29. The interior of the rear middle shell 22 is provided with a battery box for installing batteries. When the normally open mode is turned on, the front lock body 1 can be directly unlocked after rotation, which is convenient for users to enter and exit frequently; when the anti-lock mode is turned on, the magnet 26 on the rear lock rotating shaft 25 senses the Hall switch 24 to achieve anti-locking. In this mode, the unlocking is idle and cannot be unlocked, protecting the user's privacy. The main board 161 is also integrated with a Bluetooth module. The user uses a mobile phone APP to connect to the smart ball lock via Bluetooth and verify, and the lock is unlocked after the verification is passed.

[0038] Specifically, it also includes a latch lock body 3, see Figure 9 When in use, the oblique bolt lock body 3 is installed on the square rod 191 to form a complete spherical lock.

[0039] To sum up, the smart spherical lock has a streamlined structure, is safe and anti-theft, and is easy to use. It gets rid of the limitation of unlocking with a single key. When using it, you only need to press your fingerprint to unlock it, which meets the needs of users. It can also be unlocked by Bluetooth or emergency key, avoiding the troubles caused by lost keys, forgotten keys, and inconvenience in carrying. It solves the problem of frequent use and inconvenience in carrying keys, is economical, and has broad application prospects.
