For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] The present application relates to a manhole cover locking device, which includes a lock core mechanism 4000, which includes a lock core shaft 4101 and a lock tongue 4102, and the lock tongue 4102 is connected to the lock core shaft 4101. It can be understood that the manhole cover locking device also includes a lock pin and a lock housing, the lock core mechanism 4000 is arranged in the lock housing, the lock pin is arranged on the manhole cover, and the lock tongue 4102 is used to connect with the lock pin to achieve the locking of the manhole cover locking device.

[0049] The lock core mechanism 4000 includes a locking clutch assembly, which is used to clamp the lock core shaft 4101 so that the lock core shaft 4101 can rotate or cannot rotate. In conjunction with the drawings, the locking clutch assembly includes a first clutch shaft 4201, a second clutch shaft 4202 and a third clutch shaft 4203. The lock core shaft 4101 is provided with a hollow inner cavity along its own axial direction. The first clutch shaft 4201 is sleeved on the outer side of the first end of the lock core shaft 4101, the second clutch shaft 4202 is provided in the inner cavity of the lock core shaft 4101, and the third clutch shaft 4203 is sleeved on the outer side of the second end of the lock core shaft 4101. The first clutch shaft 4201 and the lock core shaft 4101 can rotate relative to each other, the second clutch shaft 4202 can reciprocate in the axial direction of the lock core shaft 4101, and the third clutch shaft 4203 can reciprocate along the axial direction of the lock core shaft 4101.

[0050] Further, the lock core mechanism 4000 includes a first locking structure 4301, a first through hole is provided on the side wall of the lock core shaft 4101, the first through hole penetrates the side wall of the lock core shaft 4101, the first locking structure 4301 is movably provided in the first through hole, and the first through hole can reciprocate in the first through hole, so as to be engaged with the second clutch shaft 4202 or the third clutch shaft 4203. In conjunction with the accompanying drawings, the outer peripheral side wall of the second clutch shaft 4202 is provided with a second engaging area, and the inner peripheral side wall of the third clutch shaft 4203 is provided with a third engaging area. It can be understood that if the first locking structure 4301 in the first through hole is partially located in the second engaging area, the first locking structure 4301 is engaged with the outer side wall of the second clutch shaft 4202; if the first locking structure 4301 in the first through hole is partially located in the third engaging area, the first locking structure 4301 is engaged with the inner side wall of the third clutch shaft 4203.

[0051] Specifically, when the manhole cover locking device is locked, the first locking structure 4301 is located near the outside of the first through hole, the first locking structure 4301 is engaged with the third engaging area, the first locking structure 4301 is engaged with the inner wall of the third clutch shaft 4203, and the second end of the lock core shaft 4101 does not protrude from the end of the third clutch shaft 4203 or the surface of the lock shell. The first clutch shaft 4201 rotates and can push the second clutch shaft 4202 to move axially along the lock core shaft 4101, and the second engaging area moves to the position corresponding to the first through hole. At this time, if pressure is applied to the third clutch shaft 4203, the third clutch shaft 4203 can be moved axially along the lock core shaft 4101, and the inner side wall of the third clutch shaft 4203 seals the first through hole and pushes the first locking structure 4301 to the other end of the first through hole, so that the first locking structure 4301 is engaged with the second engaging area. At this time, the second end of the lock core shaft 4101 protrudes from the end of the third clutch shaft 4203, so as to apply torque to the lock core shaft 4101, thereby unlocking the manhole cover locking device.

[0052] As an embodiment, the lock core mechanism 4000 includes a second locking structure 4302, which is located outside the lock core mechanism 4000. The second locking structure 4302 can be engaged with the first clutch shaft 4201 to fix the first clutch shaft 4201 and prevent it from rotating. Furthermore, the second locking structure 4302 is movable to release the engagement of the second locking structure 4302 with the first clutch shaft 4201, so that the first clutch shaft 4201 can rotate.

[0053] The outer side wall of the first clutch shaft 4201 is provided with a concave first clamping area 4204, and the second locking structure 4302 is partially located in the first clamping area 4204, so as to achieve clamping with the first clutch shaft 4201. The second locking structure 4302 is provided as a spherical structure or a cylindrical structure with a spherical end.

[0054] The movement of the second locking structure 4302 is realized by a second locking driver 4401 . The second locking driver 4401 includes a motor, and there are at least the following examples.

[0055] In some examples, the second locking structure 4302 is connected to the output end of the motor. When driven by the motor, the second locking structure 4302 approaches and engages with the first clutch shaft 4201 , or the second locking structure 4302 moves away from the first clutch shaft 4201 and is disengaged from the first clutch shaft 4201 .

[0056] In other examples, a stopper is provided at the output end of the motor, and when driven by the motor, the stopper approaches the first clutch shaft 4201 and abuts against the second locking structure 4302, so that the second locking structure 4302 remains engaged with the first clutch shaft 4201, or the stopper moves away from the first clutch shaft 4201, so that a movable space for the second locking structure 4302 is formed between the stopper and the first clutch shaft 4201, and when the first clutch shaft 4201 rotates along the first direction, the side wall of the first engaging area 4204 can push out the second locking structure 4302, thereby releasing the engagement of the second locking structure 4302 with the first clutch shaft 4201.

[0057] In some other examples, the output end of the motor is provided with a locking structure 4402, and the outer peripheral side wall of the locking structure 4402 is provided with a recessed avoidance area. The motor drives the locking structure 4402 to rotate so that the avoidance area is at a position corresponding to the second locking structure 4302. When the first clutch shaft 4201 rotates, the second locking structure 4302 moves to the avoidance area and contacts the first clutch shaft 4201. If the locking structure 4402 rotates further, the avoidance area and the second locking structure 4302 can be staggered, so that the second locking structure 4302 is engaged with the first engaging area 4204.

[0058] Other structures and operations of the manhole cover locking device are well known to those skilled in the art in the art and will not be described in detail here. It should be noted that the manhole cover locking device uses an electronic key to unlock the manhole cover, and the structure of the electronic key will be described below.

[0059] The present application relates to an electronic key, which includes a base 1000 and a key handle 2000. The base 1000 is used to fit on the surface of a lock housing, and the key handle 2000 is disposed on the base 1000. The key handle 2000 is movable on the base 1000. Specifically, the key handle 2000 can rotate on the base 1000, and along the axial direction of the key handle 2000, the key handle 2000 can move close to or away from the lock core shaft 4101, so that the key handle 2000 can connect to the lock core shaft 4101 and rotate the lock core shaft 4101. It can be understood that the key handle 2000 has an unlocking end 2300, and the unlocking end 2300 is used to connect to the lock core shaft 4101.

[0060] In conjunction with the accompanying drawings, the base 1000 is provided with a through area 1100 for installing the key handle 2000, and the through area 1100 is provided as a cylindrical through cavity. Further, the base 1000 is provided with a first installation area 1201, the key handle 2000 is provided in the first installation area 1201, and the through area 1100 is provided in the first installation area 1201.

[0061] The electronic key includes a first locking assembly, which is arranged in the base 1000. In conjunction with the drawings, the first locking assembly is arranged as the first installation area 1201. The first locking assembly is used to clamp the key handle 2000 so that the key handle 2000 cannot move, and thus the key handle 2000 cannot approach and connect to the lock core shaft 4101. Accordingly, when the user needs to use the electronic key to unlock the manhole cover locking device, the user sends a command to the electronic key through the smart terminal so that the first locking assembly releases the clamping connection of the key handle 2000.

[0062] In conjunction with the accompanying drawings, the first locking assembly includes a first locking member 3200, and the first locking member 3200 is used to clamp the key handle 2000. The first locking member 3200 has a first locking position and a first avoidance position, and the first locking member 3200 is movable to switch the first locking member 3200 to the first locking position or the first avoidance position. It can be understood that when the first locking member 3200 is in the first locking position, the first locking member 3200 is clamped with the key handle 2000, and the first locking member 3200 prevents the key handle 2000 from moving; when the first locking member 3200 is in the first avoidance position, the first locking member 3200 releases the clamping of the key handle 2000, and the key handle 2000 can move and connect to the lock core shaft 4101.

[0063] The first locking member 3200 is disposed on the outside of the key handle 2000. Specifically, the first installation area 1201 is provided with a locking activity area 1202, the locking activity area 1202 is located on the inner side wall of the penetration area 1100, and the first locking member 3200 is disposed in the locking activity area 1202 and is located on the outside of the key handle 2000. It can be understood that the first locking member 3200 is movable in the locking activity area 1202.

[0064] Further, the first locking assembly includes a first locking driver 3100, a first locking member 3200 is located at an output end of the first locking driver 3100, and the first locking driver 3100 drives the first locking member 3200 to move so that the first locking member 3200 changes position. Specifically, the first locking driver 3100 includes a motor.

[0065] As an embodiment, the first locking member 3200 is movable, and the first locking member 3200 can reciprocate to switch to the first locking position or the first avoidance position, and the moving direction of the first locking member 3200 is perpendicular to the axial direction of the key handle 2000. In this case, the first locking driver 3100 drives the first locking member 3200 to move. Under the drive of the first driver, the first locking member 3200 moves from the first locking position for engaging the key handle 2000 to the first avoidance position for avoiding the key handle 2000.

[0066] Furthermore, an eccentric structure is provided at the output end of the first locking driver 3100, and the eccentric structure is connected to the rotating shaft of the motor in the first locking driver 3100. The first locking driver 3100 drives the eccentric structure to rotate, and the eccentric structure pushes the first locking member 3200 to move. Under the push of the eccentric structure, the first locking member 3200 moves from the first locking position to the first avoidance position.

[0067] In conjunction with the accompanying drawings, the eccentric structure includes a toggle portion 3101 and a wheel body, one end of the wheel body is disposed on the rotation axis of the first locking driver 3100, the toggle portion 3101 is disposed at an eccentric position at the other end of the wheel body, and the toggle portion 3101 is used to push the first locking member 3200. Specifically, the toggle portion 3101 is configured as a lever, one end of the lever is disposed at an eccentric position at the end of the wheel body, the lever is arranged in a direction parallel to the rotation axis of the first locking driver 3100, and the side of the lever is used to abut against the first locking member 3200.

[0068] Regarding the eccentric structure, there are at least the following alternatives.

[0069] In some alternative examples, the toggle portion 3101 is configured as a protruding structure at an eccentric position on the end surface of the wheel body, and the toggle portion 3101 is integrally formed with the wheel body.

[0070] In other alternative examples, the wheel body is replaced with a connecting rod, one end of which is connected to the rotating shaft of the first locking driver 3100, and the connecting rod is perpendicular to the axial direction of the rotating shaft, and the shifting part 3101 is set as a shifting rod, which is connected to the other end of the connecting rod, and the shifting rod is perpendicular to the axial direction of the connecting rod.

[0071] In some alternative examples, the eccentric structure is configured as a cam, and the side surface of the cam is used to abut against and push the first locking member 3200 .

[0072] As an embodiment, the first locking assembly includes a first elastic member, and the first elastic member is used to push the first locking member 3200 to move from the first avoidance position to the first locking position. It can be understood that the first locking driver 3100 and the first elastic member act on both ends of the first locking member 3200 respectively, and after the first locking driver 3100 pushes the first locking member 3200, the first elastic member pushes the first locking member 3200 to move in the opposite direction.

[0073] Specifically, the first elastic member is configured as a spring, and the two ends of the first elastic member abut against the first locking member 3200 and the base 1000 respectively. When the first locking member 3200 is in the first avoidance position, the first elastic member is compressed to have a compressive elastic potential energy, and the elastic force of the first elastic member is used to push the first locking member 3200. It can be understood that, in the base 1000, the first elastic member is disposed in the locking activity area 1202, and one end of the first elastic member abuts against the inner side wall of the locking activity area 1202.

[0074] Regarding the implementation of the reciprocating movement of the first locking member 3200 , there are at least the following alternative examples.

[0075] In some alternative examples, the first locking driver 3100 drives the first locking member 3200 to move so that the first locking member 3200 moves from the first avoidance position to the first locking position. At this time, the first elastic member is pressurized and has compressive elastic potential energy, and the first elastic member is used to push the first locking member 3200 to move from the first locking position to the first avoidance position.

[0076] In some alternative examples, the first locking driver 3100 drives the first locking member 3200 to move, so that the first locking member 3200 moves from the first locking position for engaging the key handle 2000 to the first avoidance position for avoiding the key handle 2000, and the first locking member 3200 moves from the first avoidance position to the first locking position. In this case, under the drive of the first locking driver 3100, the first locking member 3200 can reciprocate.

[0077] As an embodiment, the first locking member 3200 is engaged with the outer side of the key handle 2000. Specifically, the outer side wall of the key handle 2000 is provided with an engaging area, which is recessed in the outer side wall of the key handle 2000, and the first locking member 3200 is used to engage with the engaging area. It can be understood that when the first locking member 3200 is in the first locking position, the first locking member 3200 is engaged with the engaging area, and the side of the first locking member 3200 is engaged with the side wall of the engaging area, so that the first locking member 3200 prevents the key handle 2000 from moving.

[0078] In conjunction with the accompanying drawings, the clamping area is formed into a clamping groove 2101 that is recessed on the outer wall of the key handle 2000 along a direction perpendicular to the axial direction of the key handle 2000, and the first locking member 3200 can reciprocate along the clamping groove 2101 to switch to the first locking position or the first avoidance position. It can be understood that when the first locking member 3200 is clamped with the clamping area, the first locking member 3200 is partially located in the clamping groove 2101 formed by the clamping area, and the side surface of the first locking member 3200 abuts against the inner side of the clamping area to prevent the key handle 2000 from moving in its own direction.

[0079] Furthermore, a relief notch 3201 is provided on the side of the first locking member 3200, and the relief notch 3201 is used to avoid the key handle 2000. It is understandable that when the first locking member 3200 moves to the first relief position, the relief notch 3201 is located at a position corresponding to the outside of the key handle 2000. Furthermore, the shape of the relief notch 3201 is set to be an arc-shaped notch to adapt to the shape of the outer peripheral side wall of the key handle 2000, so as to facilitate the rotation of the key handle 2000.

[0080] In some examples, a locking clamping portion 3202 is provided on the side of the first locking member 3200 facing the key handle 2000, the locking clamping portion 3202 protrudes from the side of the first locking member 3200, and an avoidance notch 3201 is provided on the side of the locking clamping portion 3202 facing the key handle 2000, and the avoidance notch 3201 is concavely formed. In other alternative examples, the avoidance notch 3201 is concavely formed on the side of the first locking member 3200 facing the key handle 2000.

[0081] As another alternative embodiment, the snap-fitting area protrudes from the outer wall of the key handle 2000, and the side of the snap-fitting area facing the unlocking end 2300 is used to abut the side of the first locking member 3200, thereby achieving the snap-fitting of the key handle 2000 and the first locking member 3200, and the key handle 2000 cannot approach the lock core shaft 4101.

[0082] Specifically, the clamping area is formed as an annular clamping portion protruding from the outer wall of the key handle 2000 .

[0083] Regarding the clamping connection between the first locking member 3200 and the key handle 2000, there is at least the following replacement scheme: on the outside of the key handle 2000, the first locking member 3200 can move to get closer to or away from the key handle 2000. When the first locking member 3200 is close to the key handle 2000, the first locking member 3200 moves to the first locking position. When the first locking member 3200 is away from the key handle 2000, the first locking member 3200 moves to the first avoidance position.

[0084] As an embodiment, the electronic key includes a second elastic member 2200, and the second elastic member 2200 is used to push the key handle 2000 to move so as to separate the key handle 2000 from the lock core shaft 4101. Specifically, the second elastic member 2200 is configured as a spring, and the two ends of the second elastic member 2200 abut against the base 1000 and the key handle 2000 respectively. When the key handle 2000 moves and connects to the lock core shaft 4101, the second elastic member 2200 is compressed and has a compressive elastic potential energy.

[0085] In conjunction with the accompanying drawings, the key handle 2000 has an operating end 2400. When a user applies force to the operating end 2400, the key handle 2000 can be moved or rotated. Further, the operating end 2400 has a shoulder, and the second elastic member 2200 is sleeved on the outer side of the key handle 2000. The two ends of the second elastic member 2200 respectively abut against the shoulder of the operating end 2400 and the end surface formed by the through area 1100 in the first installation area 1201.

[0086] As an embodiment, the inner side wall of the penetration area 1100 is provided with a recessed first limiting area 1101. Combined with the accompanying drawings, on the inner side wall of the penetration area 1100, the first limiting area 1101 is arranged along the circumferential direction, and the arc of the first limiting area 1101 along the circumference corresponds to the rotation range of the key handle 2000 when it is unlocked. The first limiting area 1101 is used to limit the rotation range of the key handle 2000.

[0087] It can be understood that the outer wall of the key handle 2000 is provided with a protruding first limiting portion 2102, and the first limiting portion 2102 is located in the first limiting area 1101. When the key handle 2000 is rotated to unlock, the first limiting portion 2102 moves along the circumference in the first limiting area 1101, and the electronic key limits the rotation angle of the key handle 2000 through the cooperation between the first limiting area 1101 and the first limiting portion 2102.

[0088] Regarding the first limiting area 1101 and the first limiting portion 2102 , as an alternative, it can at least be designed as follows: the inner wall of the penetration area 1100 is provided with a protruding first limiting area 1101 , and the outer wall of the key handle 2000 is provided with a recessed first limiting portion 2102 .

[0089] As an embodiment, the unlocking end 2300 of the key handle 2000 is connected to the end of the lock core shaft 4101 in a sleeve manner, and the unlocking end 2300 has a cylindrical cavity 2301 sleeved on the end of the lock core shaft 4101, and the inner wall of the cylindrical cavity 2301 is clamped with the lock core shaft 4101.

[0090] Specifically, the cross-section of the inner wall of the cylindrical cavity 2301 is formed into a regular polygon or a plum blossom shape, and correspondingly, the cross-section of the outer wall of the end of the lock core shaft 4101 is formed into a regular polygon or a plum blossom shape.

[0091] In some embodiments, the outer side surface of the unlocking end 2300 has an annular limiting portion 2401, the diameter of the annular limiting portion 2401 is larger than the diameter of the key handle 2000, and the annular limiting portion 2401 is formed as a regular polygon or a plum blossom shape. When the unlocking end 2300 is inserted into the lock shell, the unlocking end 2300 rotates, and the annular limiting portion 2401 abuts against the inner wall of the lock shell, so that the electronic key is fixed to the surface of the lock shell, and the key handle 2000 cannot be pulled out of the manhole cover locking device.

[0092] As an implementation method, the electronic key includes an NFC component, which is disposed in the base 1000 and is used to power the manhole cover locking device. Specifically, when the electronic key is attached to the surface of the lock housing of the manhole cover locking device, the NFC component powers the second locking driver 4401 in the lock core mechanism 4000 in an NFC connection manner, so that the second locking structure 4302 is active, thereby solving the problem of insufficient power in the manhole cover locking device outdoors. The NFC component can also send a signal to the second locking driver 4401 to start or stop the second locking driver 4401.

[0093] With reference to the accompanying drawings, a second installation area 1301 is provided in the base 1000 , and the NFC component is provided in the second installation area 1301 .

[0094] In some embodiments, the electronic key includes a PCB control board, which is disposed in the second installation area 1301. The PCB control board is electrically connected to the first locking driver 3100. The PCB control board receives information from the smart terminal and controls the first locking driver 3100 to start or shut down to achieve the activity of the first locking member 3200. On the other hand, receiving information from the smart terminal through the PCB control board enables the smart terminal to record the use of the electronic key and the opening and closing of the manhole cover locking device.

[0095] In conjunction with the accompanying drawings, a switch is provided on the side wall of the base 1000, and the switch is electrically connected to the PCB control board to realize opening or closing of the electronic key.

[0096] In some examples, a USB interface is provided on the side wall of the base 1000, and the smart terminal sends information to the PCB control board in a USB connection. In other examples, the smart terminal can also send information to the PCB control board wirelessly.

[0097] As an embodiment, a positioning structure 1400 is provided on the side of the base 1000 facing the manhole cover locking device, and the positioning structure 1400 protrudes from the side of the base 1000, and the positioning structure 1400 is set as a positioning column. Correspondingly, a recessed positioning area is provided on the surface of the lock housing, and when the electronic key is attached to the surface of the lock housing, the positioning structure 1400 and the positioning area are matched accordingly, so as to realize the positioning of the key handle 2000 and the lock core shaft 4101.

[0098] Furthermore, the base 1000 is connected to the lock housing in a magnetic way to prevent the electronic key from falling off the surface of the lock housing. Specifically, a magnet is disposed in the base 1000 .
