[0038] The utility model provides an electronic lock body.

[0039] In the embodiment of the present utility model, Figures 1 to 10 As shown, the electronic lock body includes a lock shell 10, a counter-lock tongue 20, a driving device 30, an inner handle seat 40 and a positioning assembly 50; the lock shell 10 is provided with a first through hole 11 and an electric control device; the counter-lock tongue 20 is movably mounted on the lock shell 10, and has a counter-locked state in which a portion of the counter-lock tongue 20 extends out of the first through hole 11 and an unlocked state in which the counter-lock tongue 20 is retracted into the lock shell 10, and a rack portion 21 is provided on the portion of the counter-lock tongue 20 located in the lock shell 10, and the rack portion 21 extends along the movement direction of the counter-lock tongue 20; the driving device 30 includes a driving motor 31, a first gear 32 and a transmission gear 33, the driving motor 31 is mounted on the lock shell 10 and is electrically connected to the electric control device, the first gear 32 is mounted on the lock shell 10 and is transmission-connected to the driving motor 31, the transmission gear 33 is mounted on the lock shell 10, and is coaxial with the first gear 32 and can rotate relatively , the transmission gear 33 is meshed with the rack portion 21, one of the first gear 32 and the transmission gear 33 is provided with a first abutting portion 321 and a second abutting portion 322 spaced apart in the circumferential direction, and the other is provided with a third abutting portion 331 extending between the first abutting portion 321 and the second abutting portion 322; the inner handle seat 40 is rotatably mounted on the lock housing 10, and a second gear 41 is provided on the inner handle seat 40, and the second gear 41 is meshed with the transmission gear 33; the positioning assembly 50 includes a positioning gear 51 and a first sensor 52, the positioning gear 51 is mounted on the lock housing 10 and meshed with the first gear 32, the first sensor 52 is provided on the lock housing 10, and is electrically connected to the electronic control device, the positioning gear 51 is provided with a trigger portion 511, and the positioning gear 51 has a reset position corresponding to the trigger portion 511 and the first sensor 52.

[0040] In some embodiments, the first abutting portion 321 and the second abutting portion 322 are disposed on the first gear 32 , and the third abutting portion 331 is disposed on the transmission gear 33 . When the reverse locking is completed, the third abutting portion 331 is located at the position of the first abutting portion 321, and the triggering portion 511 of the positioning gear 51 is located at the reset position matched with the first sensor 52. When the driving device 30 is used to unlock, the driving motor 31 drives the first gear 32 to rotate in the unlocking direction, and the third abutting portion 331 of the first gear 32 abuts against the second abutting portion 322 to rotate the transmission gear 33. When the transmission gear 33 rotates, it will cooperate with the rack portion 21 to drive the rack portion 21 and the reverse locking tongue 20 to retract into the first through hole 11. After the driving device 30 completes the unlocking, the driving motor 31 will rotate in the reverse direction, so that the third abutting portion 331 is away from the second abutting portion 322, and the third abutting portion 331 is close to the first abutting portion 321, so that the first gear 32 drives the transmission gear 33 to rotate when the driving device 30 is reversely locked.

[0041] When the anti-locking tongue 20 is located in the lock housing 10 and the driving device 30 performs anti-locking, the driving motor 31 drives the first gear 32 to rotate in the anti-locking direction opposite to the unlocking direction, so that the third abutting portion 331 abuts against the first abutting portion 321 to rotate the transmission gear 33. When the transmission gear 33 rotates, it cooperates with the rack portion 21 to drive the rack portion 21 to move in the direction of the first through hole 11, so that the anti-locking tongue 20 extends out of the first through hole 11. After the driving device 30 completes the anti-locking, the driving motor 31 rotates in the opposite direction, so that the third abutting portion 331 is away from the first abutting portion 321, and the third abutting portion 331 is close to the second abutting portion 322, so that the first gear 32 drives the transmission gear 33 to rotate when the driving device 30 performs unlocking.

[0042] In addition, when the anti-lock tongue 20 is in the anti-lock state and the positioning gear 51 is in the reset position, when the user presses down the inner door handle to open the door, the inner handle seat 40 rotates in the unlocking direction, driving the second gear 41 to rotate, and the second gear 41 drives the transmission gear 33 to rotate, and the transmission gear 33 drives the rack and the anti-lock tongue 20 to retract into the first through hole 11. At the same time, when the transmission gear 33 rotates, the third abutment portion 331 is spaced from the first abutment portion 321, and the third abutment portion 331 moves in the direction of the first abutment portion 321, but will not hit the first abutment portion 321, so that in the process of opening the door by the handle, the first gear 32 will not be driven by the transmission gear 33, and the rotating shaft of the drive motor 31 will not be driven, thereby avoiding wear on the drive motor 31 and extending the service life of the drive motor 31.

[0043] At the same time, after closing the door, it can also be locked by lifting the inner door handle. When the inner door handle is lifted, the inner door handle seat 40 is driven to rotate in the anti-locking direction, driving the second gear 41 to rotate, and the second gear 41 drives the transmission gear 33 to rotate, and the transmission gear 33 drives the rack to move, so that the anti-locking tongue 20 extends out of the first through hole 11 into the door frame.

[0044] The technical solution of the utility model is to set an electric control device, a first through hole 11, a reverse lock tongue 20, a driving device 30, an inner handle seat 40, and a positioning assembly 50 in the lock housing 10, wherein the reverse lock tongue 20 has a rack portion 21, the driving device 30 includes a driving motor 31, a first gear 32 and a transmission gear 33, the first gear 32 is installed in the lock housing 10, and is in transmission connection with the driving motor 31, the transmission gear 33 is installed in the lock housing 10, and is coaxial with the first gear 32 and can rotate relatively, the transmission gear 33 is meshed with the rack portion 21, one of the first gear 32 and the transmission gear 33 is provided with a first abutment portion 321 and a second abutment portion 322 spaced apart in the circumferential direction, and the other is provided with a first abutment portion 321 extending to the first abutment portion 322. The third abutment portion 331 between the contact portion 321 and the second abutment portion 322 is provided, so that the driving motor 31 drives the first gear 32 to rotate, and the first gear 32 drives the transmission gear 33 to rotate, so that the rack portion 21 and the anti-lock tongue 20 can extend out of the first through hole 11 or retract into the first through hole 11 through the driving device 30. In addition, a second gear 41 meshing with the transmission gear 33 is provided on the inner handle seat 40, and the positioning assembly 50 includes a positioning gear 51 and a first sensor 52, the first sensor 52 is provided in the housing, the positioning gear 51 is provided with a trigger portion 511, and the positioning gear 51 has a reset position corresponding to the trigger portion 511 and the first sensor 52, so that the positioning gear 51 is meshed with the first gear 32. When the door can be opened by the driving device 30 and the door inner handle seat 40, the first gear 32 can be reset by the cooperation of the positioning gear 51, so that the first gear 32, the second gear 41, and the transmission gear 33 are concentrated between the inner handle seat 40 and the driving motor 31, and the compactness of the lock body structure is improved.

[0045] In addition, in other embodiments, the first abutting portion 321 and the second abutting portion 322 are disposed on the transmission gear 33 , and the third abutting portion 331 is disposed on the first gear 32 .

[0046] In some embodiments, the positioning gear 51 is located on the side of the first gear 32 facing away from the first through hole 11. Specifically, the positioning gear 51 is located at the rear end of the anti-locking tongue 20, which is better than being located on the side of the first gear 32 facing the first through hole 11, thus avoiding the positioning gear 51 from interfering with the tongue of the anti-locking tongue 20.

[0047] In some embodiments, the first sensor 52 is a photoelectric sensor. Specifically, since the first sensor 52 is disposed inside the lock housing 10, when the first sensor 52 is a photoelectric sensor, it will not be disturbed by external ambient light, and the sensitivity of the first sensor 52 is relatively high.

[0048] In some embodiments, the first sensor 52 is a Hall sensor. Specifically, when the first sensor 52 is a Hall sensor, the first sensor has a higher sensitivity and a longer service life.

[0049] In some embodiments, the anti-locking tongue 20 is provided with a waist-shaped hole 22, which extends along the movement direction of the anti-locking tongue 20, and the inner handle seat 40 is arranged in the waist-shaped hole 22. Specifically, the inner handle seat 40 is rotatably arranged inside the anti-locking tongue 20, and compared with the case where the handle seat is arranged beside the anti-locking tongue 20, the installation space of the handle seat and the anti-locking tongue 20 partially overlaps, which can further improve the compactness of the lock body structure.

[0050] In some embodiments, the outer circumferential surface of the second gear 41 is provided with a toothed area and a toothless area, the toothed area and the toothless area are arranged in the circumferential direction of the second gear 41, and the toothed area is provided with transmission teeth that match the transmission gear 33. Specifically, the circumferential surface of the second gear 41 is only provided with transmission teeth in the circumferential surface portion that matches the transmission gear 33, and the circumferential surface portion that does not match the transmission gear 33 during rotation is not provided with transmission teeth, so that the structure of the second gear 41 is simpler, the volume of the toothless area can be set smaller, and the volume of the second gear 41 and the space occupancy rate in the lock housing 10 are reduced.

[0051] In some embodiments, the second gear 41 is provided with a second positioning mark 413, and the second positioning mark 413 is arranged on the end face of the second gear 41 facing away from the anti-lock tongue 20 and close to the circumference of the second gear 41. Specifically, the second positioning mark 413 can be set to a position facing the drive motor 31 when the anti-lock tongue 20 is in the unlocked state. When assembling the electronic lock body and installing the anti-lock tongue 20, the anti-lock tongue 20 needs to be installed to the unlocked state. When installing the second gear 41, the second positioning mark 413 is arranged to face the drive motor 31. In this way, after the second gear 41 is installed, the toothed area is arranged at a position that can cooperate with the transmission gear 33, which is more convenient during assembly. In addition, in other embodiments, the second positioning mark 413 can also be set to a direction facing away from the drive motor 31 when in the unlocked state.

[0052] In some embodiments, the first gear 32 is provided with a first positioning mark 323, and the first positioning mark 323 is provided on the end face of the first gear 32 and close to the circumference of the first gear 32. Specifically, the first positioning mark 323 can be set to face the direction of the drive motor 31 when the positioning gear 51 is in the reset position, so that when assembling the electronic lock body and installing the first gear 32, it is only necessary to install the first positioning mark 323 in the direction of the drive motor 31, so that the first abutment portion 321 and the second abutment portion 322 can be set in a position that can cooperate with the third abutment portion 331, which is more convenient for users during assembly. In addition, in other embodiments, the first positioning mark 323 can also be set to face the direction away from the drive motor 31 when the positioning gear 51 is in the reset position.

[0053] In some embodiments, the lock housing 10 is provided with a second sensor 16 and a third sensor 17, and the second sensor 16 and the third sensor 17 are both electrically connected to the electric control device. When the driving device 30 drives the anti-lock tongue 20 to move to the anti-lock state, the anti-lock tongue 20 triggers the second sensor 16, and when the driving device 30 drives the anti-lock tongue 20 to move to the unlocked state, the anti-lock tongue 20 triggers the third sensor 17. Specifically, when the anti-lock tongue 20 is driven by the driving motor 31 to anti-lock or open the door, the position of the anti-lock tongue 20 can be detected, so that it can be ensured that the anti-lock tongue 20 moves to the specified position under the drive of the driving device 30.

[0054] In some embodiments, the lock housing 10 is provided with a second through hole 12, and the electronic lock body further includes a cross oblique tongue 13, a limiting mechanism 14 and a first elastic member 15. The cross oblique tongue 13 is movably mounted on the lock housing 10. The first elastic member 15 connects the lock housing 10 and the cross oblique tongue 13, and has elastic deformation for driving the cross oblique tongue 13 to extend out of the second through hole 12. The limiting mechanism 14 has a limiting member 143 movably mounted in the lock housing 10. The limiting member 143 has a limiting state and an avoidance state. In the limiting state, the limiting member 143 is located on a side of the cross oblique tongue 13 away from the second through hole 12 to limit the cross oblique tongue 13 from retracting into the second through hole 12. In the avoidance state, the limiting member 143 is spaced apart from the cross oblique tongue 13.

[0055] Specifically, after locking the door, the reverse bolt 20 extends out of the first through hole 11 into the door frame, and the cross-slanted bolt 13 extends out of the second through hole 12 into the door frame. The stopper 143 is in a limit state to limit the cross-slanted bolt 13. When opening the door, the reverse bolt 20 is retracted into the lock housing 10, and the stopper 143 moves to a evasive position spaced from the cross-slanted bolt 13, so that the cross-slanted bolt 13 can be retracted into the lock housing 10 under the action of external force. In this way, the user can directly move the door panel so that the cross-slanted bolt 13 contacts the door frame, and the cross-slanted bolt 13 is retracted into the lock housing 10 under the pressure of the door frame. Compared with the traditional common slanted bolt, when the stopper 143 limits the cross-slanted bolt 13, the cross-slanted bolt 13 cannot be squeezed into the lock housing 10 by external force. In this way, illegal elements can be prevented from prying the lock by squeezing the cross-slanted bolt 13, thereby improving the safety of the electronic lock body. Further, the first elastic member 15 can be a spring.

[0056] In some embodiments, the limiting mechanism 14 includes an unlocking paddle 141 and a third gear 142. The third gear 142 is rotatably mounted on the inner handle seat 40 and is coaxial with and spaced apart from the transmission gear 33. The third gear 142 is meshed with the second gear 41 and is transmission-connected to the limiting member 143 through the unlocking paddle 141 to drive the limiting member 143 to move from the limiting state to the avoidance state.

[0057] Specifically, when the driving device 30 drives the anti-lock bolt 20 to unlock, the first gear 32 drives the third gear 142 to move and rotate, so that the third gear 142 drives the unlocking paddle 141 to move, and when the unlocking paddle 141 moves, it drives the limiting member 143 to move from the limiting state to the avoiding state, so that the user can directly move the door, and the cross-latched bolt 13 can be retracted into the lock housing 10 after contacting the door frame. In this way, the driving device 30 releases the limit of the cross-latched bolt 13 by the limiting member 143 while releasing the anti-lock, which is more convenient for the user to open the door without additionally controlling the limiting member 143.

[0058] Further, the unlocking paddle 141 is arranged between the third gear 142 and the limiting member 143, and can move in the direction in which the third gear 142 and the limiting member 143 face each other. The unlocking paddle 141 is provided with a first toggle portion 1411 at one end close to the third gear 142, and a second toggle portion 1412 at one end close to the limiting member 143. The third gear 142 is provided with a second matching portion 1421 matching with the first toggle portion 1411, and the limiting member 143 is provided with a first matching portion 1431 matching with the second toggle portion 1412. When the reverse lock is released by the driving device 30, the third gear 142 is driven to rotate by the first transmission gear 33, and at the same time, the second matching portion 1421 toggle the unlocking paddle 141 to move in the direction close to the third gear 142, so that the second toggle portion 1412 toggle the first matching portion 1431, so that the limiting member 143 moves from the limiting state to the avoiding state, and the cross-oblique tongue 13 can be retracted into the lock housing 10. In this way, the transmission structure between the third gear 142 and the unlocking paddle 141 is relatively simple.

[0059] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
