[0045] As Figures 1-12 shown, the intelligent U-shaped fingerprint password lock of the present utility model includes a lock beam 1, a lock body 2, an electric lock core 3, a PCB control component 4, a password module 5, a fingerprint module 6 and a power module 7. The lock beam 1 is U-shaped. The electric lock core 3, the PCB control component 4, the fingerprint module 6 and the power module 7 are all installed inside the lock body 2, and the password module 5 is installed on the surface side of the lock body 2. Specifically, in this embodiment, the lock body 2 has a rectangular structure, and a receiving cavity 8 is provided on one surface of the lock body 2. A power supply compartment 9, a fingerprint module compartment 10, a first lock core compartment 11 and a lock tongue groove 12 are formed in the receiving cavity 8. The power module 7 includes a rechargeable battery and a charging component. The power module 7 is installed in the power supply compartment 9 and has a charging port passing through the bottom surface of the lock body 2 to connect to an external power supply or for charging. The fingerprint module 6 is used to collect fingerprint information. The fingerprint module 6 is installed in the fingerprint module compartment 10 and the sensor 13 of the fingerprint module 6 is exposed on the bottom surface of the lock body 2. The electric lock core 3 is fixedly installed in the first lock core compartment 11 and is electrically connected to the PCB control component 4. The PCB control component 4 is installed in the receiving cavity 8. The password module 5 is installed on the PCB control component 4 and closes the receiving cavity 8. The power module 7 is electrically connected to the PCB control component 4. The PCB control component 4 is electrically connected to the electric lock core 3. The PCB control component 4 is also electrically connected to the password module 5 and the fingerprint module 6. When the PCB control component 4 receives a matching fingerprint or password, it sends an unlocking instruction to the electric lock core 3 to control the electric lock core 3 to unlock.
[0046] Further, in this embodiment, the PCB control component 4 includes a board support 14, a main control board 15, and a protection board 16. The board support 14 is fixedly installed in the accommodation cavity 8, the main control board 15 is tightly installed on the board support 14, and the protection board 16 covers the main control board 15. Specifically, several mounting posts 17 are provided in the accommodation cavity 8, and the board support 14 is tightly installed on the mounting posts 17 by screws. The board support 14 is preferably integrally formed of PC plastic, which can effectively reduce the production cost. The main control board 15 is a PCB circuit board, and the main control board 15 is electrically connected to the electric lock core 3, the fingerprint module 6, and the password module 5. When the main control board 15 receives a matching fingerprint or password, it sends an unlocking instruction to the electric lock core 3, thereby controlling the electric lock core 3 to unlock and realizing the intelligence of the lock. The protection board 16 is made of stainless steel plate to enhance the strength of the protection board 16 to prevent the lock from being easily pried open and improve the anti-prying effect of the lock. The password module 5 includes a light guide layer 18, a touch panel 19, and a panel 20. The light guide layer 18, the touch panel 19, and the panel 20 are sequentially installed on the upper surface of the protection board 16. Among them, the light guide layer 18 is a light guide foam that plays a role in guiding light; the touch panel 19 is a touch PCB board with a touch button function to realize password input for unlocking; the panel 20 is an acrylic board. The touch panel 19 presses the light guide layer 18 and is tightly installed on the upper surface of the protection board 16 by screws, and the panel 20 is attached to the upper surface of the touch panel 19. It should be noted that the above-mentioned power module 7, main control board 15, password module 5, and fingerprint module 6 have been widely used in smart homes and will not be elaborated here.
[0047] Further, in this embodiment, several pairs of bayonets 21 are symmetrically arranged on the two inner sides of the lock beam 1. Two symmetrical lock beam holes 22 are provided on the end face of the lock body 2. The lock beam holes 22 are circular through holes. The main body of the lock beam 1 is a cylinder. The lock beam 1 can pass through the lock beam holes 22 to lock with the lock body 2. The shape of the lock beam holes 22 is adapted to the shape of the main body of the lock beam 1, and is not limited to the circular through hole matching the cylinder. Specifically, the lock tongue groove 12 is a semi-circular groove. The two ends of the lock tongue groove 12 respectively extend to the two lock beam holes 22 of the lock body 2 to form two symmetrical lock tongue holes 23. A slidable first lock tongue 24 and a second lock tongue 25 are installed in the lock tongue groove 12. The lock tongue can enter and exit the lock tongue hole 23 in its sliding direction, that is, the first lock tongue 24 can enter and exit the lock tongue hole 23 on one side of the lock tongue groove 12 when sliding axially, and the second lock tongue 25 can enter and exit the lock tongue hole 23 on the other side of the lock tongue groove 12 when sliding axially. The front ends of the first lock tongue 24 and the second lock tongue 25 are both formed as clamping protrusions 26. When the lock beam 1 passes through the lock beam holes 22, the clamping protrusions 26 can be clamped into the bayonets 21, thereby locking the lock beam 1 to the lock body 2. More specifically, when the first lock tongue 24 slides out towards the lock beam hole 22, the clamping protrusion 26 on the first lock tongue 24 is clamped into the bayonet 21 on one side of the lock beam 1; at this time, the second lock tongue 25 also slides out towards the lock beam hole 22 on the other side at the same time, and the clamping protrusion 26 on the second lock tongue 25 is clamped into the bayonet 21 on the other side of the lock beam 1, that is, the lock is in the locked state. When the first lock tongue 24 slides and contracts in the lock tongue hole 23 on one side, the clamping protrusion 26 on the first lock tongue 24 disengages from the bayonet 21 on one side of the lock beam 1; at this time, the second lock tongue 25 also slides and contracts in the lock tongue hole 23 on the other side at the same time, and the clamping protrusion 26 on the second lock tongue 25 disengages from the bayonet 21 on the other side of the lock beam 1, that is, the lock is in the unlocked state.
[0048] Particularly, in this embodiment, a countersunk hole 27 is provided inside the lock beam hole 22. The countersunk hole 27 allows the locking screw 28 to pass through the lock body 2 and reach the accommodation cavity 8. The locking screw 28 is preferably a countersunk screw. Four locking screws 28 respectively pass through the corresponding countersunk holes 27 to fasten the protective plate 16 to the lock body 2, and the top of the locking screw 28 does not protrude from the inner surface of the lock beam hole 22. Such a setting is to enable the lock beam 1 to be smoothly inserted into the lock beam holes 22, and after the lock beam 1 is inserted into the lock beam holes 22, the lock beam 1 can block the locking screws 28. In the state where the lock is not unlocked, the locking screws 28 cannot be disassembled, thereby improving the anti-theft effect of the lock. Preferably, in order to improve the convenience of disassembling and assembling the locking screw 28, a first through hole 29 is opened on the side surface of the lock body 2 corresponding to the countersunk hole 27. The first through hole 29 can also be of the countersunk type. The locking screw 28 can pass through the first through hole 29 to reach the countersunk hole 27, and then be threadedly connected to the protective plate 16. In this embodiment, the first through hole 29 is blocked by a hole plug 30, which can play a role in beautifying the appearance of the lock. The hole plug 30 is preferably formed by silicone injection molding, and the production cost is low.
[0049] Further, in this embodiment, the lock tongue groove 12 is provided with a first limiting ring 31 and a second limiting ring 32. The first lock tongue 24 is provided with a first spring seat 33, and the second lock tongue 25 is provided with a second spring seat 34. A first spring 35 is installed on the first spring seat 33, and a second spring 36 is installed on the second spring seat 34. Specifically, the first spring 35 is a compression spring. After being compressed, the first spring 35 is limited by the first limiting ring 31, thereby pre-tightening the first lock tongue 24. The second spring 36 is also a compression spring. After being compressed, the second spring 36 is limited by the second limiting ring 32, thereby pre-tightening the second lock tongue 25. The first spring 35 and the second spring 36 enable the first lock tongue 24 and the second lock tongue 25 to be installed in the lock tongue groove 12 in a pre-tightened state. At this time, under the action of the compression spring, the convex blocks 26 of the first lock tongue 24 and the second lock tongue 25 both extend into the lock beam hole 22. When the lock beam 1 is inserted into the lock beam hole 22, the lock beam 1 presses against the convex blocks 26, thereby forcing the first lock tongue 24 and the second lock tongue 25 to contract inward. When the convex block 26 reaches the bayonet 21, the tension of the compression spring will force the first lock tongue 24 and the second lock tongue 25 to extend outward, so that the convex block 26 is stuck into the bayonet 21, thereby locking the lock beam 1. Preferably, in order to facilitate the lock beam 1 to enter the lock beam hole 22 more smoothly and unlock the lock tongue, the front end of the lock beam 1 is set in the shape of a frustum 37. In order to facilitate the convex block 26 to reach the rear bayonet 21, the rear end of the bayonet 21 can be set as an inclined surface 38, and the last bayonet 21 is not provided with an inclined surface 38 all the time.
[0050] Further, in this embodiment, a first clamping block 39 is provided at the rear end of the first lock tongue 24, and a second clamping block 40 is provided at the rear end of the second lock tongue 25. The front end of the electric lock core 3 is a first fork 41, and the first fork 41 is alternately abutted against the first clamping block 39 and the second clamping block 40. The electric lock core 3 drives the first fork 41 to rotate clockwise by 90 degrees. The first fork 41 pushes the first clamping block 39 and the second clamping block 40, so that the first lock tongue 24 and the second lock tongue 25 contract synchronously. At this time, the lock is in the unlocked state. When the electric lock core 3 stops working, the lock tongue will extend outward under the action of the compression spring. The first fork 41 is driven to rotate counterclockwise by 90 degrees passively under the action of the first clamping block 39 and the second clamping block 40. At this time, the lock body 2 is in the waiting-to-be-locked state. It should be noted that in some embodiments where the lock tongue cannot automatically extend, the electric lock core 3 can also be set to actively drive the lock tongue to extend outward. For example, as long as the electric lock core 3 is set to have a forward and reverse rotation function, it can be realized. At this time, the electric lock core 3 rotates forward to unlock and rotates in reverse to lock.
[0051] Further, in this embodiment, to improve the practicality of the lock, the smart lock is also provided with a mechanical lock core 42, which can also drive the first lock tongue 24 and the second lock tongue 25 to synchronously extend and retract, preventing the inability to unlock in case of a circuit failure. Specifically, the accommodation cavity 8 further forms a second lock core chamber 43, the mechanical lock core 42 is installed in the second lock core chamber 43, the front end of the mechanical lock core 42 is a second fork 44, a third latch 45 is further provided at the rear end of the first lock tongue 24, and a fourth latch 46 is further provided at the rear end of the second lock tongue 25. The second fork 44 is alternately abutted against the third latch 45 and the fourth latch 46. An external force drives the mechanical lock core 42 to drive the second fork 44 to rotate clockwise by 90 degrees through the key. The second fork 44 pushes the third latch 45 and the fourth latch 46, causing the first lock tongue 24 and the second lock tongue 25 to synchronously contract. At this time, the lock is in the unlocked state. When the external force is removed, the lock tongue will extend outward under the action of the compression spring, and the second fork 44 is driven to rotate counterclockwise by 90 degrees passively under the action of the third latch 45 and the fourth latch 46. At this time, the lock body 2 is in the waiting-to-be-locked state. It should be noted that in some embodiments where the lock tongue cannot automatically extend, when the mechanical lock core 42 is in the unlocked state, an external force drives the mechanical lock core 42 to rotate counterclockwise by 90 degrees through the key. The second fork 44 pushes the third latch 45 and the fourth latch 46, causing the first lock tongue 24 and the second lock tongue 25 to synchronously extend. At this time, the lock can also be manually locked.
[0052] Further, in this embodiment, the rear ends of the first lock tongue 24 and the second lock tongue 25 are both formed as semi-cylinders, and the two semi-cylinders can be adaptively installed in the lock tongue groove 12 when combined, so as to effectively reduce the volume of the lock and improve the user experience. Preferably, to improve the waterproof effect of the lock, the first lock tongue 24 and the second lock tongue 25 are respectively configured with a first rubber sleeve 47 and a second rubber sleeve 48 to isolate the lock beam hole 22, and a moisture-proof board 49 is provided at the bottom of the lock body 2 to isolate the power module 7 and the mechanical lock core 42. Specifically, the first rubber sleeve 47, the second rubber sleeve 48 and the moisture-proof board 49 are all preferably silicone sleeves. The first rubber sleeve 47 is sleeved on the back side of the first spring seat 33. A first rubber sleeve position 50 is provided in the accommodation cavity 8, and the first rubber sleeve 47 is installed in the first rubber sleeve position 50 and is closely attached to the edge of the corresponding lock tongue hole 23. The second rubber sleeve 48 is sleeved on the back side of the second spring seat 34. A second rubber sleeve position 51 is provided in the accommodation cavity 8, and the second rubber sleeve 48 is installed in the second rubber sleeve position 51 and is closely attached to the edge of the corresponding lock tongue hole 23, thereby preventing moisture from entering the accommodation cavity 8 from the lock beam hole 22 through the lock tongue hole 23 and improving the waterproof effect of the lock. A groove 52 is provided at the bottom of the lock body 2, and the moisture-proof board 49 is installed in the groove 52. The moisture-proof board 49 has a convex portion, and the convex portion can be embedded into the charging port and the key hole to prevent moisture from entering the accommodation cavity 8 from the charging port and the key hole, further improving the waterproof effect of the lock.
[0053] For the intelligent lock implementing the present utility model, after the lock beam 1 is inserted into the lock body 2, the first lock tongue 24 and the second lock tongue 25 will retract inwards. After the bayonet 21 of the lock beam 1 reaches the positions of the first lock tongue 24 and the second lock tongue 25, the lock tongues pop out, and the clamping protrusion 26 is clamped into the bayonet 21 to achieve locking. The state after locking is as shown in Figure 6 shown. After locking, the 4 KM3x6 countersunk head screws on both sides of the protective plate 16 can be inserted into the lock body 2 by a screwdriver but cannot pass through the lock beam 1 for disassembly, realizing the anti-disassembly function; after locking, even if the front panel 20 of the lock is damaged, since the protective plate 16 is embedded inside the lock to form an integral body with the lock body 2, it is also impossible to pry open the lock with a screwdriver or a specific tool, realizing anti-prying.
[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0055] The above-described embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
