The lock body 1 comprises a first installation area 14 and a second installation area 15, the first installation area 14 and the second installation area 15 are sealed and isolated, the key unlocking assembly 2, the button unlocking assembly 3, and the barge shaft dial wheel 6 are installed in the first installation area 14, and the two ends of the barge shaft dial wheel 6 are respectively connected to the key unlocking assembly 2 , the key unlocking assembly 3, the lock beam 4, the lock beam elastic member 41, the barge shaft assembly 5, and the limiting bead 42 are installed in the second installation area 15, one end of the barge shaft assembly 5 is inserted into the first installation area 14 and connected to the axis of the barge shaft dial wheel 6, one end of the lock beam 4 is connected to the lock body 1 through the lock beam elastic member 41, and the other end of the lock beam 4 is connected to the lock hole on the lock body 1, and the limiting bead 42 is arranged between the barge shaft assembly 5 and the lock beam 4, and the lock beam 41 is provided with a clamping groove 43, and the limiting bead 42 is clamped in the clamping groove 43 when locked. The limiting bead 42 is preferably a steel ball. The lock beam elastic member 41 is preferably a lock beam 4 spring. The key unlocking assembly 2 and the key unlocking assembly 3 together constitute the inner shell assembly 8, and the inner shell assembly 8 includes an inner shell 81, and the key unlocking assembly 2 and the key unlocking assembly 3 are assembled on the inner shell 81. The inner shell 81 is a part of the lock body 1.

[0032] There are two sets of unlocking structures inside the lock body 1, one set is a key unlocking assembly 2 for unlocking with a key, and the other set is a key unlocking assembly 3 for unlocking with a password input. The two sets of assemblies are respectively connected to the barge shaft dial wheel 6. Using either set of assemblies alone can drive the barge shaft dial wheel 6 to rotate, and then the barge shaft assembly 5 rotates to make the limit bead 42 avoid the lock beam 4 to achieve unlocking. The first installation area 14 is used to assemble the key unlocking assembly 2, the key unlocking assembly 3, and the barge shaft dial wheel 6, and needs to be waterproof and sealed, while the second installation area 15 will be exposed to the outside, so the first installation area 14 and the second installation area 15 must be isolated by a seal to keep the first installation area 14 waterproof and sealed.

[0033] like Figure 3 and 4 As shown, the barge shaft assembly 5 includes a first bearing 53, a barge shaft 51, and a barge shaft return torsion spring 52. One end of the barge shaft 51 is connected to the axis of the barge shaft dial wheel 6, and the other end of the barge shaft 51 is connected to the lock body 1 through the first bearing 53. The barge shaft return torsion spring 52 is wound on the barge shaft 51, and one end of the barge shaft return torsion spring 52 is fixed to the barge shaft 51, and the other end is fixed to the lock body 1. Through the first bearing 53, the barge shaft 51 can rotate freely relative to the lock body 1. The barge shaft return torsion spring 52 provides a reset torsion force to the barge shaft 51. After unlocking, the avoidance position 54 of the barge shaft 51 is aligned with the limit bead 42. At this time, the barge shaft return torsion spring 52 is in a twisted state. When the lock beam 4 is reinserted into the lock body 1, the limit bead 42 will be pushed to the locking groove 43 of the lock beam 4 under the torsion of the barge shaft return torsion spring 52 to complete the locking. The first bearing 53 is preferably a deep groove ball bearing.

[0034] The barge shaft 51 is provided with an avoidance position 54. When unlocking, the barge shaft 51 rotates to the avoidance position 54 and is aligned with the limiting bead 42. When locking, the barge shaft 51 rotates to the avoidance position 54 and is staggered with the limiting bead 42. The lock beam 4 is provided with a clamping groove 43. When locking, the barge shaft 51 presses against the limiting bead 42, so that the limiting bead 42 is clamped in the clamping groove 43, and the lock beam 4 is limited to achieve a locking effect; when unlocking, the avoidance position 54 of the barge shaft 51 provides space for the limiting bead 42 to move. At this time, the limiting force of the limiting bead 42 on the lock beam 4 is insufficient. Under the elastic force of the lock beam elastic member 41, the lock beam 4 will push the limiting bead 42 away and bounce up to complete unlocking, and the limiting bead 42 is pushed toward the avoidance position 54.

[0035] like Figure 5As shown, the key unlocking assembly 2 includes a lock drive assembly, a lock clutch shaft 22, a clutch shaft spring 23, and a key lock 21.

[0061] The working principle of the switch lock of this smart padlock:

[0062] Fingerprint password unlocking principle:

[0063] (1) In the locked state, the user inputs the unlocking command on the key panel 39 with a fingerprint or password, and the output shaft of the unlocking motor 32 rotates 180° clockwise, and at the same time drives the motor dial 31 to rotate 180° clockwise. The motor dial 31 rotates 180° clockwise and drives the shaft dial 6 to rotate 90° counterclockwise, and at the same time drives the shaft assembly 5 to rotate 90° counterclockwise. At this time, the clearance position 54 of the shaft 51 is aligned with the limit bead 42, and the lock beam 4 is pushed upward to the stop position under the action of the spring force of the lock beam 4. While the lock beam 4 moves upward, it pushes the limit to the clearance position 54 of the shaft assembly 5 to achieve unlocking; at this time, the unlocking motor 32 rotates 180° clockwise, pauses for about 5 seconds, and rotates 180° counterclockwise, and the unlocking motor 32 returns to the initial position to complete the unlocking action.

[0064] (2) In the unlocked state, the user aligns the lock beam 4 with the lock hole of the lock body 1 and presses the lock beam 4 downward into place. At this time, the return spring 52 of the barge shaft causes the barge shaft assembly 5 to rotate 90° clockwise under the action of torque, and the barge shaft assembly 5 returns to its original position, while driving the barge shaft dial wheel 6 to return to its original position, completing a cycle of unlocking and locking.

[0065] Key unlocking principle:

[0066] (1) In the locked state, the user inserts the key, and the key pushes the lock clutch shaft 22, which is connected to the lock drive gear 24. At the same time, the key rotates 90° clockwise, driving the lock clutch shaft 22 and the lock drive gear 24 to rotate 90° clockwise, driving the barge shaft dial wheel 6 to rotate 90° counterclockwise, and synchronously driving the barge shaft assembly 58 to rotate 90° counterclockwise. At this time, the clearance position 54 of the barge shaft 51 is aligned with the limiting bead 42. Under the action of the spring force of the lock beam 4, the lock beam 4 is pushed upward to the stop point position. While the lock beam 4 moves upward, it pushes the limiting bead 42 to the clearance position 54 of the barge shaft assembly 58, thereby unlocking the lock;

[0067] (2) In the unlocked state, the user aligns the lock beam 4 with the lock hole of the lock body 1 and presses the lock beam 4 downward into place. At this time, the shaft return torsion spring 52 causes the shaft assembly 5 to rotate 90° clockwise under the action of torque, and the shaft assembly 5 returns to its original position, while driving the shaft dial wheel 6 to return to its original position. The lock beam 4 is limited by the limiting bead 42. After locking is completed, the key is pulled out, and the lock head clutch shaft 22 returns to its original position under the elastic force of the clutch shaft spring 23. At the same time, the lock head drive gear 24 returns to its original position under the torsion of the lock head return torsion spring 26, completing a cycle of unlocking and locking.

[0068] The anti-theft mechanical principle of this smart padlock:

[0069] In this case, the key is used to unlock the lock while pushing the lock clutch shaft 22 to connect to the lock drive gear 24. After unlocking, the key is pulled out and the lock clutch shaft 22 and the lock drive gear 24 are disconnected under the elastic force of the clutch shaft spring 23. If the key is not correct, the lock cylinder 27 cannot be correctly arranged and the lock clutch shaft 22 cannot be pushed to connect with the lock drive gear 24. Even if the lock cylinder 27 can be opened, it will only rotate idly and cannot open the smart padlock.

[0070] The products currently on the market generally use a mechanical key to directly unlock the lock, which has a limited anti-theft level. However, the present invention uses a key to unlock the lock while connecting the clutch to unlock the lock, which improves the key anti-theft level and reaches a super C-level lock core 27.

[0071] The waterproof principle of this physical button combined with the key's multi-mode unlocking:

[0072] (1) Waterproof principle of fingerprint head installation area: In this case, the circuit board assembly 36 is fixed to the lock body 1 with M2X4 cross slot countersunk screws 92, and the key waterproof pad 38 is used to achieve IP68 waterproof with the lock body 1 and the circuit board 37.

[0073] (2) Waterproof principle of the installation area of ​​the lock beam 4 and the shaft assembly 5: In this case, the waterproof pressure plate assembly 7 is fixed to the lock body 1 with M2.5X6 cross slot countersunk screws 91, and the shaft waterproof pad 71 is used to achieve IP68 waterproofness with the lock body 1 and the shaft waterproof pressure plate 72; the waterproof ring and the G4 shaft waterproof pad 71 are designed as an integrated structure, thereby meeting the IP68 waterproof requirement, such as Fig. 9 shown.

[0074] (3) The general waterproofing technology can be used to waterproof other areas to meet the IP68 waterproofing requirements.

[0075] The waterproof rating of products on the market is generally IP65 to IP66 (rain). If you want to reach IP67 to IP68 (water immersion), the competing products are usually filled with waterproof glue, which makes them impossible to repair and have defects such as rework. The smart padlock of the present invention can not only meet the IP68 (water immersion) standards, but also be easy to assemble and maintain.

[0076] like Fig.11 As shown, in this smart padlock, the physical button is combined with the waterproof membrane button panel 39 device

[0077] Working principle:

[0078] Waterproof principle of fingerprint head installation area: This case adopts PVC key panel (membrane key panel 39) touch deformation to press the key waterproof pad 38, the key waterproof pad 38 presses the touch switch 372 on the circuit board 37 to transmit user instructions.

[0079] The current products on the market are generally mechanical buttons, and the touch button products are too small to touch and have interference. However, this case uses a physical button combined with a film button panel 39 device working principle to achieve the appearance of a touch effect.

[0080] The present invention covers a smart padlock with a key anti-theft mechanical structure; a smart padlock with an IP68 waterproof structure; and a smart padlock with a physical password key combined with a membrane key panel 39. This smart padlock uses a key-pushing clutch combination structure to achieve a key-opened anti-theft structure device. Technical unlocking can only open the lock head, but not the smart lock, because the clutch is disconnected, which solves the key anti-theft level and reaches a super C-level lock core 27. This smart padlock uses a silicone pad to design a double-ring waterproof structure, which solves the problem that a single waterproof ring cannot be completely waterproof, and the embarrassment that it cannot be repaired after being filled with waterproof glue. It is both waterproof and convenient for maintenance, reducing unnecessary cost losses. This smart padlock uses a physical password key combined with a membrane key panel 39 structure to achieve a simple and elegant appearance with a strong sense of integrity.

[0081] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
