In one embodiment, the locking assembly 130 includes a locking member 131 movably disposed on the lock body assembly 110 and an unlocking member 132 rotatably disposed on the lock body assembly 110, one end of the locking member 131 is movable into or out of the locking slot 121, the unlocking member 132 has a slot 1321, and the unlocking member 132 rotates to align the slot 1321 with or away from the locking member 131 so that the locking member 131 can move into or out of the slot 1321. When the smart padlock 100 is locked, one end of the locking member 131 moves into the locking slot 121, and the other end of the locking member 131 moves out of the escape slot 1321 and abuts against the outer wall of the rotated unlocking member 132.

The latch 131 and the unlocking member 132 are disposed in the upper lock body 112. The clutch assembly 140 rotates the unlocking member 132 to align the relief slot 1321 with or away from the locking member 131. When the slot 1321 is aligned with the latch 131, the latch 131 may move in the upper lock body 112, such that one end of the latch 131 may move out of the latch slot 121 and the other end may move into the slot 1321, at this time, the shackle 120 is unlocked from the lock body assembly 110, one end of the latch 131 abuts against an outer wall of the shackle 120, movement of the latch 131 in the upper lock body 112 is limited, and meanwhile, the other end of the latch 131 is located in the slot 1321 to clamp the latch 132, such that the latch 132 cannot rotate, and the smart padlock 100 is in an unlocked state. When shackle 120 is depressed such that the short arm of shackle 120 is positioned in upper lock body 112, blocking member 131 may move within upper lock body 112 such that one end of blocking member 131 may move into blocking slot 121 and the other end may move out of offset slot 1321. Then, the clutch assembly 140 may rotate the unlocking member 132, so that the relief slot 1321 is far away from the locking member 131, and the other end of the locking member 131 abuts against the outer wall of the unlocking member 132, to limit the movement of the locking member 131 in the upper lock body 112, and meanwhile, one end of the locking member 131 is located in the locking slot 121 to lock the shackle 120, so that the shackle 120 is locked to the lock body assembly 110, and the smart padlock 100 is in the locked state, as shown in fig. 5 and 15.

Further, the latch member 131 is disposed perpendicular to the unlocking member 132.

After latching pin 1311 is aligned with the escape slot 1321, the latch hook 120 can move upward, thereby allowing ball 1312 to move along the inner wall of latching slot 121 to gradually move out of latching slot 121, and at the same time, ball 1312 moves latching pin 1311 in upper latch body 112, so that latching pin 1311 moves into escape slot 1321. When the latch hook 120 is pressed down on the lock body, the latching pin 1311 drives the ball 1312 to move in the upper lock body 112, so that the ball 1312 moves into the latching groove 121, and at the same time, the relief groove 1321 moves away from the latching pin 1311, the latching pin 1311 abuts against the outer wall of the unlocking member 132, and the movement of the latching pin 1311 is limited, so that the ball 1312 is clamped in the latching groove 121. Alternatively, the unlocking member 132 may be an eccentric structure such as a cam.

In one embodiment, the locking assembly 130 further includes a locking elastic member 133 disposed in the lock body assembly 110, the locking elastic member 133 is sleeved on the locking member 131, one end of the locking elastic member 133 abuts against the lock body assembly 110, and the other end abuts against the locking member 131, and the elastic force of the locking elastic member 133 can keep the locking member 131 in the locking groove 121. Alternatively, the locking elastic member 133 is a spring or other elastic member such as a bellows or the like.

When the intelligent padlock 100 is in the locked state, the elastic force of the locking elastic member 133 may cause one end of the locking member 131 to be located in the locking groove 121 and the other end to abut against the outer wall of the unlocking member 132. Referring to fig. 5 to 7 and 15 to 17, when unlocking member 132 rotates to align relief slot 1321 with locking member 131, the other end of locking member 131 is no longer restrained by the outer wall of unlocking member 132 and can move in upper lock body 112, and at this time, the force of upward movement of locking hook 120 can move the end of locking member 131 out of locking slot 121, and locking member 131 compresses locking spring 133 during the moving process. After the end of the locking member 131 is completely moved out of the locking slot 121, the end of the locking member 131 is always abutted against the outer wall of the locking hook 120 under the elastic force of the locking elastic member 133, and the other end of the locking member 131 is moved into the receding slot 1321, so that the locking hook 120 is unlocked. Referring to fig. 2 to 4 and 12 to 14 again, after the latch hook 120 is pressed down and the latching groove 121 of the latch hook 120 is aligned with the latch member 131, one end of the latch member 131 moves into the latching groove 121 by the elastic force of the latch elastic member 133 while the other end of the latch member 131 moves out of the relief groove 1321, and then the unlocking member 132 rotates to move the relief groove 1321 away from the latch member 131, and the other end of the latch member 131 abuts against the outer wall of the unlocking member 132 to restrict the movement of the latch member 131 in the lock body, so that the latch member 131 locks the latch hook 120.

Referring to fig. 1, 2, 5, 9, 12, 15, and 18, in an embodiment, the smart padlock 100 further includes a shackle elastic member 190 disposed in the lock body assembly 110, one end of the shackle elastic member 190 abuts against the lock body assembly 110, and the other end abuts against an end of the shackle 120, and an elastic force of the shackle elastic member 190 may move the other end of the shackle 120 out of the lock body assembly 110. Latch hook spring 190 may provide an upward force to latch hook 120 such that latch hook 120 may automatically move upward under the force of latch hook spring 190 after unlocking member 132 unlocks lockout member 131. Optionally, the latch hook elastic member 190 is a spring or other elastic member such as a bellows or the like.

The axis of shackle spring 190 coincides with the axis of shackle 120. When the latch hook 120 is locked to the upper latch body 112, the end of the latch member 131 is positioned in the latch groove 121 and the other end abuts against the outer wall of the unlocking member 132 to restrict the upward movement of the latch hook 120, and at this time, the latch hook 120 compresses the latch hook elastic member 190 since the latch hook 120 cannot move upward. It will be appreciated that the spring force of the shackle spring 190 is greater than the spring force of the latching spring 133, and the spring force of the shackle spring 190 will always cause the shackle 120 to have an upward tendency to move, but the latch member 131 cannot move in the upper latch body 112 because the outer wall of the unlocking member 132 stops the latch member 131. After the unlocking element 132 aligns the offset slot 1321 with the locking element 131, at this time, the locking hook 120 may automatically move upward under the elastic force of the locking hook elastic element 190, and the other end of the locking element 131 may move in the upper lock body 112 without being limited by the outer wall of the unlocking element 132, and at this time, the end of the locking element 131 may move out of the locking slot 121 by the upward moving force of the locking hook 120 until the locking hook elastic element 190 is in a free state, so as to unlock the locking hook 120.

Of course, in other embodiments of the present invention, the latch hook elastic member 190 may not be provided, and the latch hook 120 may be pulled upward directly by an external force.

In one embodiment, the driving assembly 150 includes a gear motor 151 and a rotating shaft 152 installed at an end of the gear motor 151, the rotating shaft 152 is connected to the clutch assembly 140, and the rotating shaft 152 is disconnected or connected to the unlocking member 132 through the clutch assembly 140. The reduction motor 151 is a power source for unlocking the smart padlock 100. Of course, in other embodiments of the present invention, the reduction motor 151 may be replaced by another rotatable power source. Alternatively, the reduction motor 151 includes a motor and a reducer installed at an output end of the motor. Specifically, the rotating shaft 152 is fixed at the output end of the gear motor 151, and the gear motor 151 can drive the rotating shaft 152 to rotate synchronously when rotating.

When the clutch assembly 140 is at the engaged position, the clutch assembly 140 connects the rotating shaft 152 and the locking assembly 130, and the rotating shaft 152 can drive the clutch assembly 140 to rotate, thereby driving the unlocking member 132 to move. When the clutch assembly 140 is at the off position, the clutch assembly 140 disconnects the rotating shaft 152 from the locking assembly 130, the gear motor 151 and the rotating shaft 152 cannot drive the unlocking member 132 to rotate, and the unlocking member 132 remains stationary.

Referring to fig. 1 to 8, in the first embodiment of the present invention, the driving assembly 150 is in clutch connection with the clutch assembly 140, and specifically, the rotating shaft 152 is in clutch connection with the clutch assembly 140. When the clutch assembly 140 is at the off position, the clutch assembly 140 is in transmission connection with the unlocking member 132, the rotating shaft 152 is in separation connection with the clutch assembly 140, and at this time, the gear motor 151 drives the rotating shaft 152 to be incapable of driving the clutch assembly 140 to rotate, so that the clutch assembly 140 and the unlocking member 132 are kept static. The structure of the clutch assembly 140 is specifically as follows:

in one embodiment, the clutch assembly 140 includes a clutch shaft 141 rotatably sleeved on the rotating shaft 152 and connected to the unlocking member 132, and a clutch member 142 retractable in a radial direction, an inner wall of the clutch shaft 141 has a clutch protrusion 1411, the clutch member 142 is partially disposed on the rotating shaft 152, and a protruding end of the clutch member 142 abuts against the inner wall of the clutch shaft 141 and is rotatable along the inner wall of the clutch shaft 141 and the clutch protrusion 1411, and the clutch protrusion 1411 can stop the clutch member 142 to drive the unlocking member 132 to rotate or allow the clutch member 142 to slide so as to keep the unlocking member 132 stationary.

The clutch shaft 141 is a rotating shaft structure, one end of the clutch shaft 141 is sleeved on the rotating shaft 152, the other end of the clutch shaft 141 is in transmission connection with the unlocking piece 132, and the clutch shaft 141, the rotating shaft 152 and the unlocking piece 132 are coaxially arranged to avoid the influence of eccentric rotation on unlocking of the intelligent padlock 100. One end of the clutch shaft 141 facing the rotation shaft 152 has a clutch inner hole, and the clutch shaft 141 is sleeved on the end of the rotation shaft 152 through the clutch inner hole. The inner wall of the clutch inner hole is provided with a clutch projection 1411, and the surface of the clutch projection 1411, which is matched with the clutch member 142, is an inclined surface, i.e. a clutch inclined surface.

The rotation shaft 152 has a mounting hole in a radial direction, the clutch member 142 is movably mounted in the mounting hole, and an end of the clutch member 142 is always abutted against an inner wall of a clutch inner hole of the clutch shaft 141. When the clutch member 142 contacts with the clutch projection 1411, there are two situations, namely, the clutch projection 1411 stops the clutch member 142, so that the rotating shaft 152 drives the clutch shaft 141 to rotate synchronously through the clutch member 142; the other is that the clutch member 142 slides along the clutch protrusion 1411, at this time, the rotating shaft 152 cannot drive the clutch shaft 141 to rotate through the clutch member 142, and the clutch shaft 141 remains stationary.

Referring to fig. 5 to 8, when the intelligent padlock 100 is unlocked, the clutch relationship between the rotating shaft 152 and the clutch shaft 141 is engaged and then disengaged. Specifically, the gear motor 151 drives the rotating shaft 152 to rotate, the rotating shaft 152 drives the clutch member 142 therein to rotate synchronously, when the end of the clutch member 142 abuts against the clutch protrusion 1411, the clutch protrusion 1411 stops the rotation of the clutch member 142, at this time, the rotating shaft 152 can drive the clutch shaft 141 to rotate synchronously by the engagement of the clutch member 142 and the clutch protrusion 1411, and then the clutch shaft 141 drives the unlocking member 132 to rotate, so that the avoiding groove 1321 aligns with the locking member 131. After the latch member 131 moves into the relief groove 1321, the latch member 131 abuts against an inner wall of the relief groove 1321 to restrict the rotation of the unlocking member 132, and thus the rotation of the clutch shaft 141 connected to the unlocking member 132. The clutch shaft 141 is kept still, the reduction motor 151 continues to rotate, and the rotating force continues to move the clutch member 142, so that the clutch member 142 slides along the clutch projection 1411, and the clutch member 142 gradually retracts into the mounting hole while sliding along the clutch projection 1411. When the end of the clutch member 142 is disengaged from the clutch protrusion 1411, the clutch member 142 protrudes from the mounting hole and continues to slide along the inner wall of the clutch inner hole, and so on until the rotation of the reduction motor 151 stops. This can avoid the problem of stalling caused by the inability of the reduction motor 151 to rotate.

Referring to fig. 1 to 8, in an embodiment, the clutch assembly 140 further includes a clutch elastic member 143, the clutch elastic member 143 is disposed on the rotating shaft 152 along a radial direction, one end of the clutch elastic member 143 abuts against the rotating shaft 152, the other end of the clutch elastic member 143 abuts against an inner wall of the clutch shaft 141, and the clutch elastic member 143 is configured to enable the clutch member 142 to always abut against the inner wall of the clutch shaft 141. Alternatively, the clutch elastic member 143 is a spring, a bellows, or other members having elastic properties. The elastic clutch member 143 is always in a compressed state, so that the elastic force of the elastic clutch member 143 can make the clutch member 142 have a tendency to protrude out of the mounting hole, so as to ensure that the clutch member 142 is always abutted against the inner wall of the clutch inner hole. And, when the clutch member 142 slides along the clutch projection 1411, the clutch member 142 gradually retracts into the mounting hole against the elastic force of the clutch elastic member 143, and when the clutch member 142 leaves the clutch projection 1411, the clutch member 142 extends out of the mounting hole by the elastic force of the clutch elastic member 143. Optionally, the clutch member 142 is a clutch lever or a rolling element such as a steel ball or the like.

In one embodiment, the clutch shaft 141 has a stopper portion 1412 protruding in a radial direction, and the lock body assembly 110 has a stopper groove rotatably mounted on the stopper portion 1412, and an inner wall of the stopper groove may intermittently contact with an outer wall of the stopper portion 1412 to limit a rotation angle of the clutch shaft 141. The lower lock body 113 has a limiting groove, and the limiting groove may rotatably mount the limiting portion 1412. And, after the spacing portion 1412 rotates a certain angle in the spacing groove, the spacing portion 1412 can abut against the inner wall of the spacing groove to limit the rotation angle of the spacing portion 1412, and then limit the rotation angle of the clutch shaft 141, so that the clutch shaft 141 can only rotate within a certain angle range. This prevents the clutch shaft 141 from over-travel rotation, so that the clutch shaft 141 can accurately drive the unlocking member 132 to rotate, the slot 1321 of the unlocking member 132 can be accurately aligned with the locking member 131, and the slot 1321 can be prevented from rotating over the locking member 131.

Optionally, the limiting portion 1412 is a sector, and correspondingly, the limiting groove is a sector groove matched with the limiting portion 1412. When the radial side wall of the sector block abuts against the radial side wall of the sector groove, the sector block cannot rotate, and the clutch shaft 141 is shown to move in place. Optionally, the positions of the limiting part 1412 and the limiting groove may be interchanged, that is, the lower lock body 113 is provided with the limiting block, and the clutch shaft 141 is provided with the limiting groove.

In an embodiment, the clutch assembly 140 further includes a twisting member 144, the twisting member 144 is disposed on the clutch shaft 141, one end of the twisting member 144 is fixed to the clutch shaft 141, the other end of the twisting member 144 abuts against the lock body assembly 110, and the elastic force of the twisting member 144 can reset the rotated clutch shaft 141. Alternatively, the torsion member 144 is a torsion spring, a coil spring, or the like. When the rotating shaft 152 drives the clutch shaft 141 to rotate through the clutch member 142, the rotating shaft 152 overcomes the elastic force of the twisting member 144 to enable the twisting member 144 to store energy, and simultaneously, the clutch shaft 141 drives the unlocking member 132 to rotate, so that the relief groove 1321 aligns with the locking member 131 to unlock the intelligent padlock 100. When the locking member 131 moves out of the slot 1321, the locking member 131 stops the unlocking member 132, and the elastic force of the twisting member 144 resets the clutch shaft 141, so that the clutch shaft 141 drives the unlocking member 132 to reset.

Further, the elastic force of the clutch elastic member 143 is greater than the sum of the elastic forces of the latch hook elastic member 190 and the torsion member 144. Thus, when the clutch member 142 abuts against the clutch projection 1411, the elastic force of the clutch elastic member 143 causes the clutch member 142 to always abut against the clutch projection 1411 and not to slip over the clutch projection 1411; when the unlocking member 132 is locked and fixed by the locking member 131, the force for driving the rotation shaft 152 to rotate is greater than the elastic force of the clutch elastic member 143, so that the clutch member 142 slides along the clutch protrusion 1411, and gradually compresses the clutch elastic member 143, so that the reduction motor 151 idles, and the occurrence of rotation blockage is avoided.

In an embodiment, the clutch shaft 141 further has an adaptor 1413 extending along the axial direction and an engaging portion 1414 fixing the twisting member 144, the adaptor 1413 is connected to the unlocking member 132 to drive the unlocking member 132 to rotate, the twisting member 144 is sleeved on the adaptor 1413, one end of the twisting member 144 is engaged with the engaging portion 1414, and the other end of the twisting member 144 abuts against the lock body assembly 110. The adaptor 1413 protrudes in the axial direction to facilitate the sheathing of the twisting member 144; meanwhile, the clutch shaft 141 and the unlocking member 132 are connected through the adapting portion 1413, so that the clutch shaft 141 can drive the unlocking member 132 to move synchronously. The engaging portion 1414 may be provided on the clutch shaft 141 or on the adapter 1413. Illustratively, the chucking part 1414 is disposed on the adaptor part 1413.

When the twister 144 is in the free state, the intelligent padlock 100 is in the locked state, and the clutch shaft 141 and the rotation shaft 152 are kept in a relative stationary state. When the intelligent padlock 100 is unlocked, the clutch shaft 141 can compress the twisting member 144 under the action of the rotating force, and after the rotating force disappears, if the locking member 131 stops the limiting of the unlocking member 132, the twisting member 144 can be reset. Alternatively, the number of the catching portions 1414 may be plural to adjust the twisting force of the twisting member 144.

Referring to fig. 9 to 20, in the second embodiment of the present invention, the clutch assembly 140 is detachably connected to the locking assembly 130, and specifically, the clutch assembly 140 is detachably connected to the unlocking member 132. When the clutch assembly 140 is at the off position, the clutch assembly 140 is in transmission connection with the rotating shaft 152, the clutch assembly 140 is in separation connection with the unlocking member 132, and at this time, the rotating shaft 152 cannot drive the unlocking member 132 to rotate through the clutch assembly 140, so that the unlocking member 132 is kept static. The structure of the clutch assembly 140 is specifically as follows:

referring to fig. 9 to 11, in an embodiment, the clutch assembly 140 includes a clutch shaft 141 axially movably disposed in the rotating shaft 152 and rotatable with the rotating shaft 152, the clutch shaft 141 having a projection 1415 projecting in an axial direction, and the unlocking member 132 having a clutch portion 1322 projecting toward the clutch member 142. Engagement of projection 1415 with clutch 1322 may cause unlocking member 132 to rotate or projection 1415 to move up and down along clutch 1322. The rotation shaft 152 has a mounting hole for mounting the clutch shaft 141, and the clutch shaft 141 is mounted in the mounting hole and can move up and down in the mounting hole. When the reduction motor 151 drives the rotating shaft 152 to rotate, the clutch shaft 141 in the rotating shaft 152 can be driven to rotate synchronously.

The clutch shaft 141 is coaxially disposed with the rotation shaft 152 and the unlocking member 132 to prevent the eccentric rotation from affecting the unlocking of the intelligent padlock 100. The unlocking member 132 has a protruding clutch portion 1322 at an end toward the clutch shaft 141, and the clutch shaft 141 has a protruding protrusion 1415 at an end toward the unlocking member 132, and the clutch portion 1322 may be engaged with the protrusion 1415. The surface of the protrusion 1415, which is engaged with the engaging and disengaging portion 1322, is an inclined surface, i.e., an engaging and disengaging inclined surface. When the protrusion 1415 contacts the clutch part 1322, there are two cases, namely, the protrusion 1415 stops the clutch part 1322, so that the clutch shaft 141 drives the unlocking member 132 to rotate synchronously by the engagement of the protrusion 1415 and the clutch part 1322, as shown in fig. 15 to 17; alternatively, the protrusion 1415 slides along the clutch portion 1322, and the clutch shaft 141 cannot rotate the unlocking member 132 through the protrusion 1415, and the unlocking member 132 remains stationary, as shown in fig. 18 to 20.

Referring to fig. 9, 15 to 20, when the intelligent padlock 100 is unlocked, the clutch shaft 141 and the unlocking member 132 are engaged and then disengaged. Specifically, the reduction motor 151 drives the rotation shaft 152 to rotate, the rotation shaft 152 drives the clutch shaft 141 therein to rotate synchronously, when the protruding portion 1415 abuts against the clutch portion 1322, the clutch portion 1322 stops the rotation of the protruding portion 1415, and at this time, the clutch shaft 141 can drive the unlocking member 132 to rotate synchronously by the cooperation of the protruding portion 1415 and the clutch portion 1322, so that the receding slot 1321 aligns with the locking member 131. After the latch member 131 moves into the relief groove 1321, the latch member 131 may abut against the inner wall of the relief groove 1321 to restrict the rotation of the unlocking member 132, and the unlocking member 132 remains stationary. The decelerating motor 151 continues to rotate the rotating shaft 152 and the clutch shaft 141 therein, and the rotating force causes the protrusion 1415 to slide along the clutch portion 1322, and the protrusion 1415 gradually moves downward in the mounting hole while sliding along the clutch portion 1322. When the end of the extension 1415 is disengaged from the engaging and disengaging portion 1322, the extension 1415 moves upward in the mounting hole and continues to rotate with the rotating shaft 152, and so on until the rotation of the reduction motor 151 stops. This can avoid the problem of stalling caused by the inability of the reduction motor 151 to rotate.

Optionally, the number of the protruding portions 1415 is multiple, the protruding portions 1415 are uniformly arranged, correspondingly, the number of the clutch portions 1322 is multiple, and the clutch portions 1322 are uniformly arranged and correspond to the protruding portions 1415 one to one. Thus, the engagement of the protruding portions 1415 and the clutch portions 1322 can ensure that the clutch shaft 141 drives the unlocking member 132 to rotate smoothly, thereby preventing play. Illustratively, the number of the protruding portions 1415 is two, and the number of the clutching portions 1322 is two.

In an embodiment, the clutch assembly 140 further includes a clutch elastic member 143, the clutch elastic member 143 is disposed in the rotating shaft 152, and one end of the clutch elastic member 143 abuts against the rotating shaft 152, and the other end abuts against the clutch shaft 141, so that the protruding portion 1415 is always engaged with the clutch portion 1322. Alternatively, the clutch elastic member 143 is a spring, a bellows, or other members having elastic properties. When the clutch elastic member 143 is in a free state, the clutch shaft 141 is at the highest position in the mounting hole, but does not protrude out of the mounting hole, and the clutch portion 1322 engages with the protrusion 1415 in the mounting hole. When the clutch member 142 is in the free state, the clutch portion 1322 is displaced from the projecting portion 1415 and at least partially overlaps in the vertical direction. And, when the extension 1415 slides along the clutch part 1322, the clutch shaft 141 gradually moves downward in the mounting hole against the elastic force of the clutch elastic member 143, and when the extension 1415 is separated from the clutch part 1322, the clutch shaft 141 moves upward in the mounting hole by the elastic force of the clutch elastic member 143.

Referring to fig. 9 to 11, in an embodiment, the clutch shaft 141 has a position-limiting portion 1412 extending in a radial direction, the rotating shaft 152 has a position-limiting groove 1521 extending in an axial direction, the position-limiting groove 1521 is used for movably mounting the position-limiting portion 1412, and the rotating shaft 152 drives the clutch shaft 141 to rotate through the cooperation between the position-limiting portion 1412 and the position-limiting groove 1521. Alternatively, the clutch elastic member 143 is a spring, a bellows, or other members having elastic properties. The engagement of the position-limiting portion 1412 and the position-limiting groove 1521 can limit the rotation of the clutch shaft 141 in the rotating shaft 152, so that the clutch shaft 141 can accurately move up and down in the rotating shaft 152. The limiting groove 1521 is an open groove along the vertical direction, the limiting part 1412 is installed in the limiting groove 1521, and the clutch shaft 141 compresses the clutch elastic part 143 under the action of the external force of the unlocking part 132 and moves downwards along the limiting groove 1521 through the limiting part 1412; when the external force is lost, the clutch shaft 141 moves upward along the stopper groove 1521 through the stopper portion 1412 by the elastic force of the clutch elastic member 143.

In one embodiment, the unlocking member 132 has a radially protruding protrusion 1323, and the lock body assembly 110 has a fitting groove for rotatably mounting the protrusion 1323, and a fitting inner wall may intermittently contact with an outer wall of the protrusion 1323 to limit a rotation angle of the unlocking member 132. The lower latch body 113 has a mating slot that can rotatably receive the boss 1323. And, after the certain angle is rotated in the cooperation groove to bulge 1323, bulge 1323 can with the inner wall butt of cooperation groove to the turned angle of restriction bulge 1323, and then the turned angle of restriction release piece 132 makes release piece 132 can only rotate at certain angular range. This prevents the unlocking member 132 from being overtravel rotated so that the escape slot 1321 of the unlocking member 132 can be accurately aligned with the latching member 131 to prevent the escape slot 1321 from rotating past the latching member 131.

Alternatively, the protrusion 1323 is a sector and correspondingly, the mating groove is a sector that mates with the protrusion 1323. When the radial side wall of the sector block abuts against the radial side wall of the sector groove, the sector block cannot rotate, and the clutch shaft 141 is shown to move in place. Alternatively, the positions of the protrusion 1323 and the matching groove may be interchanged, that is, the lower lock body 113 is provided with a limiting block, and the unlocking member 132 is provided with a matching groove.

Referring to fig. 1, 2, 5, 9, 12, 15 and 18, in one embodiment, the driving assembly 150 further includes an electronic circuit 160, the electronic circuit 160 is communicatively coupled to a matching handheld device for receiving power and communication from the handheld device, and the electronic circuit 160 is electrically coupled to the geared motor 151 for supplying power to the geared motor 151 to control the geared motor 151 to rotate. The electronic circuitry 160 is wirelessly connected to the handheld device for power and communication. Optionally, the electronic circuit 160 is an NFC electronic circuit. An electronic circuit 160 may be installed in the lower lock body 113, and the reduction motor 151 is electrically connected to the electronic circuit 160. The electronic circuit 160 stores therein identity information of the smart padlock 100.

If the identity authentication is passed, namely the handheld device is matched with the intelligent padlock 100, the handheld device can be unlocked; if the identity authentication is not passed, i.e. the handheld device is not matched with the intelligent padlock 100, the handheld device cannot perform the unlocking operation. Moreover, after the handheld device and the intelligent padlock 100 perform identity authentication and pass, the handheld device can supply power to the electronic circuit 160, and then the electronic circuit 160 supplies power to the reduction motor 151 through electrical connection, so as to control the reduction motor 151 to rotate. After the gear motor 151 rotates, the unlocking member 132 can be driven to rotate by the rotating shaft 152 and the clutch shaft 141, so that the intelligent padlock 100 is unlocked.

Further, the electronic circuit 160 is an electronic circuit including an NFC communication module and an NFC energy management module, and the handheld device is a mobile phone, a smart band, or a tablet computer having an NFC function.

It should be noted that a built-in power supply is not required in the lock body assembly 110, and the electronic circuit 160 can cooperate with the handheld device to perform identity recognition and wireless power supply, so as to supply power to the reduction motor 151 and realize the control of the rotation of the reduction motor 151.

Referring to fig. 1, 2, 5, 9, 12, 15 and 18, in an embodiment, the smart padlock 100 further includes a first detection assembly 170, and the first detection assembly 170 is used for detecting the locking and unlocking states of the smart padlock 100. The first detecting element 170 can detect the position of the shackle 120 to determine whether the shackle 120 is in the unlocked state or the locked state, and thus know the state of the intelligent padlock 100 according to the state of the shackle 120.

Further, the first detecting element 170 includes a first sensing element 171 and a first detecting element 172, the first sensing element 171 is disposed on the latch hook 120, the first detecting element 172 corresponds to the first sensing element 171 when the latch hook is latched and is electrically connectable to the electronic circuit 160, and the first detecting element 172 can detect the approaching and the departing of the first sensing element 171. That is, the first sensing member 171 is disposed opposite to the first detecting member 172. When the locking hook 120 is in the locking position, the first sensing member 171 faces the first detecting member 172, and at this time, the first detecting member 172 can detect the first sensing member 171. When the hook 120 is in the unlocking position, the first sensing element 171 is far away from the first detecting element 172, and at this time, the first sensing element 171 is not detected by the first detecting element 172. Meanwhile, the first detecting member 172 transmits the current position information of the first sensing member 171 to the electronic circuit 160, and the electronic circuit 160 may determine the state of the intelligent padlock 100 according to the current position information and transmit the same to an external device.

Referring to fig. 9, 12, 15 and 18, in an embodiment, the intelligent padlock 100 further includes a second detection assembly 180, and the cooperation of the second detection assembly 180 and the first detection assembly 170 is used to detect the operating state and the abnormal state of the intelligent padlock 100. For example, the first detecting component 170 and the second detecting component 180 cooperate to detect the unlocking and locking states of the intelligent padlock 100, whether the shackle 120 is pressed and locked, whether the intelligent padlock 100 is in an abnormal state, and the like.

Further, the second detecting assembly 180 includes a second sensing element 181 and a second detecting element 182, the second sensing element 181 is disposed on the unlocking element 132, the second detecting element 182 corresponds to the second sensing element 181 when locked and is electrically connectable to the electronic circuit 160, and the second detecting element 182 can detect the approaching and the moving away of the second sensing element 181. That is, the second sensing member 181 is disposed opposite to the second sensing member 182. When the unlocking member 132 moves the relief groove 1321 away from the locking member 131, the second sensing member 181 faces the second sensing member 182, and the second sensing member 181 can be sensed by the second sensing member 182. When the unlocking member 132 aligns the relief slot 1321 with the locking member 131, the second sensing member 181 is far away from the second detecting member 182, and at this time, the second sensing member 181 is not detected by the second detecting member 182. Meanwhile, the second sensing member 182 transmits the current position information of the second sensing member 181 to the electronic circuit 160, and the electronic circuit 160 may determine the state of the intelligent padlock 100 according to the current position information and transmit the state to an external device.

The detection mode of the first detection assembly 170 and the second detection assembly 180 is as follows: the first sensing member 171 is detected by the first detecting member 172, and the second sensing member 181 is detected by the second detecting member 182, indicating that the intelligent padlock 100 is in the locked state. The first sensing member 171 is not detected by the first detecting member 172, and the second sensing member 181 is not detected by the second detecting member 182, indicating that the intelligent padlock 100 is in the unlocked state. The first sensing member 171 is detected by the first detecting member 172, and the second sensing member 181 is not detected by the second detecting member 182, which indicates that the locking hook 120 has been pressed downward, but the relief slot 1321 of the unlocking member 132 is aligned with the locking member 131. The first sensing member 171 is not detected by the first detecting member 172, and the second sensing member 181 is detected by the second detecting member 182, which indicates that the intelligent padlock 100 is abnormally started, and requires attention of an operator.

It can be understood that, when the first sensing element 172 detects the first sensing element 171 and the second sensing element 182 does not detect the second sensing element 181, the first unlocking element 132 and the second unlocking element 132 can transmit the position of the locking hook 120 and the position of the unlocking element 132 to the electronic circuit 160, the electronic circuit 160 controls the deceleration motor 151 to rotate reversely, and the deceleration motor 151 is further engaged with the unlocking element 132 through the rotating shaft 152 and the clutch shaft 141 to drive the unlocking element 132 to rotate reversely, so that the relief slot 1321 is far away from the locking element 131; until the second sensing member 181 is sensed by the second sensing member 182, the second sensing member 182 transmits the position of the unlocking member 132 to the electronic circuit 160, indicating that the relief slot 1321 has been separated from the locking member 131, and the electronic circuit 160 controls the deceleration motor 151 to stop the reverse rotation. The unlocking element 132 is reset by the cooperation of the second detecting element 182 and the second sensing element 181, so that the intelligent padlock 100 is locked.

It is worth noting that the intelligent padlock 100 can detect the locking and unlocking states of the intelligent padlock 100 only by the first detection assembly 170, as shown in the first embodiment; the first detection assembly 170 and the second detection assembly 180 can be used to detect the operation state and abnormal state of the intelligent padlock 100, as shown in the second embodiment.

Optionally, the first detecting element 172 and the second detecting element 182 are magnetic induction sensors, and the first sensing element 171 and the second sensing element 181 are magnetic elements. Further, the first detecting element 172 and the second detecting element 182 are reed switches or hall elements, and the first sensing element 171 and the second sensing element 181 are magnetic steels. When the first sensing element 171 corresponds to the first detecting element 172 and the second sensing element 181 corresponds to the second detecting element 182, the first detecting element 172 is connected with the first sensing element 171 through magnetic induction, and the second detecting element 182 is connected with the second sensing element 181 through magnetic induction, so as to indicate that the shackle 120 is in the locking position, and further indicate that the intelligent padlock 100 is in the locking state; after the first sensing element 171 is far away from the first detecting element 172 and the second sensing element 181 is far away from the second detecting element 182, the first detecting element 172 cannot be connected to the first sensing element 171 through magnetic induction, and the second detecting element 182 cannot be connected to the second sensing element 181 through magnetic induction, so as to indicate that the shackle 120 is in the unlocking position, and further indicate that the intelligent padlock 100 is in the unlocking state. Of course, the first detecting element 172 and the second detecting element 182 may be position sensors, and the first sensing element 171 and the second sensing element 181 are sensing pieces.
