[0037] The present utility model provides an electronic lock body.

[0038] In the embodiments of the present utility model, as Figures 1 to 10 shown, the electronic lock body includes a lock case 10, a locking tongue assembly 20, a driving device 30, and an inner handle base 40; the lock case 10 is provided with a first lock hole 11 and an electronic control device; the locking tongue assembly 20 includes a deadlocking tongue 21, the deadlocking tongue 21 is movably installed in the lock case 10 and has a deadlocking state of protruding from the first lock hole 11 and an unlocking state of retracting into the first lock hole 11; the driving device 30 includes a driving motor 31, the driving motor 31 is electrically connected to the electronic control device and is in transmission connection with the deadlocking tongue 21, and the driving motor 31 is at least used to drive the deadlocking tongue 21 to move from the deadlocking state to the unlocking state; the inner handle base 40 is rotatably installed on the lock case 10, the inner handle base 40 is used for connecting with the inner door handle, and the inner handle base 40 is in transmission connection with the deadlocking tongue 21 to drive the deadlocking tongue 21 to move from the deadlocking state to the unlocking state when the inner handle base 40 rotates in the unlocking direction, and to drive the deadlocking tongue 21 to move from the unlocking state to the deadlocking state when the inner handle base 40 rotates in the opposite direction of the unlocking direction.

[0039] Specifically, when the user needs to open the door on the lock body, the user can input the password or fingerprint through the panel set on the door, or input the unlocking instruction through the mobile phone connected to the lock. After receiving the unlocking instruction, the driving motor 31 will drive the deadlocking tongue 21 to retract into the first lock hole 11, so that the user can unlock without using the key. Moreover, when the user is inside the door, the user can directly press down the handle, causing the inner handle base 40 to rotate in the unlocking direction, driving the deadlocking tongue 21 to move from the deadlocking state to the unlocking state, so that the deadlock can be released directly through the handle inside the door. After closing the door inside the door, the user can directly lift the handle, causing the inner handle base 40 to rotate in the opposite direction of the unlocking direction, thereby driving the deadlocking tongue 21 to move from the unlocking state to the deadlocking state.

[0040] The utility model is provided with a first lock hole 11 in a lock case 10 and an anti-lock tongue 21 movably installed in the lock case 10. The anti-lock tongue 21 has an anti-lock state of protruding from the first lock hole 11 and an unlocked state of retracting into the first lock hole 11. At the same time, an electric control device and a driving motor 31 connected to the electric control device are provided, and the driving motor 31 is in transmission connection with the anti-lock tongue 21 and can drive the anti-lock tongue 21 to move from the anti-lock state to the unlocked state. In addition, an inner handle seat 40 rotatably installed in the lock case 10 is provided. When the inner handle seat 40 rotates in the unlocking direction, it drives the anti-lock tongue 21 to move from the anti-lock state to the unlocked state. When the inner handle seat 40 rotates in the opposite direction of the unlocking direction, it drives the anti-lock tongue 21 to move from the unlocked state to the anti-lock state. In this way, by pressing down the inner door handle, the inner handle seat 40 can be rotated in the unlocking direction, so that the anti-lock tongue 21 can be unlocked. Moreover, by lifting the inner door handle, the inner handle seat 40 can be rotated in the opposite direction of the unlocking direction, so that the anti-lock tongue 21 can be locked. In this way, compared with the method of anti-locking the electronic lock through a mechanical knob inside the door, the method of locking by lifting the inner door handle is simpler, and the user experience is better.

[0041] In some embodiments, the handle seat is provided with a square groove 43. During installation, the inner door handle is installed on the inner door handle seat through the square groove 43.

[0042] In some embodiments, the electronic lock body further includes a sensing device 50. The sensing device 50 is disposed in the lock case 10 and is electrically connected to the electric control device. The sensing device 50 is configured to be triggered when the door is closed. The electric control device is used to control the driving motor 31 to drive the anti-lock tongue 21 to move from the unlocked state to the anti-lock state when the sensing device 50 is triggered. Specifically, when the user closes the door, the sensing device 50 is triggered, the electric control device starts the driving motor 31, and then the driving motor 31 drives the anti-lock tongue 21 to protrude from the first lock hole 11 to the anti-lock state. In this way, automatic anti-locking is achieved when the user closes the door, and the user does not need to perform manual anti-locking, and the user experience is better.

[0043] In some embodiments, the sensing device 50 further includes a safety bevel tongue 51, a first sensor 52, and a first elastic member 53. The lock case 10 is provided with a second lock hole 12. The safety bevel tongue 51 is movably installed in the lock case 10 and has a first position of protruding from the second lock hole 12 and a second position of retracting into the second lock hole 12. The first elastic member 53 has an elastic deformation that drives the safety bevel tongue 51 to move to the first position. The first sensor 52 is disposed in the lock case 10, and the first sensor 52 is triggered when the safety bevel tongue 51 moves to the second position.

[0044] Specifically, an abutment member is provided on the door frame at a position corresponding to the safety latch 51, so that when the door is closed, the safety latch 51 is squeezed by the door frame and retracted into the second lock hole 12, and the abutment member prevents the safety latch 51 from extending out of the second lock hole 12. After each door opening, the first elastic member 53 drives the safety latch 51 to move to the second position extending out of the second lock hole 12, so that the safety latch 51 is spaced from the first sensor 52, so that each time the door is closed, the safety latch 51 can trigger the first sensor 52 to automatically reverse lock.

[0045] Furthermore, the first sensor 52 is a mechanical trigger switch and is disposed at the rear end of the safety latch 51. In other embodiments, the first sensor 52 may also be configured as a Hall switch.

[0046] In some embodiments, the portion of the anti-lock tongue 21 located inside the lock housing 10 is provided with a rack portion 211, which extends along the movement direction of the anti-lock tongue 21. The driving device 30 also includes a first gear 32, which is meshed with the rack portion 211 and is transmission-connected to the driving motor 31. A second gear 41 is provided on the inner handle seat 40, which is meshed with the first gear 32.

[0047] Specifically, when the electric control device controls the driving motor 31 to open or lock the door, the driving motor 31 drives the first gear 32 to rotate, and the first gear 32 drives the rack portion 211 to move, so that the anti-locking tongue 21 extends out or retracts into the first lock hole 11, so as to switch the anti-locking tongue 21 between the anti-locking state and the unlocking state. In addition, in other embodiments, a lever structure for moving the anti-locking tongue 21 is provided.

[0048] When the door is opened or locked by the inner door handle, the inner door handle drives the second gear 41 to rotate, and the second gear 41 drives the first gear 32 to rotate, so that the anti-locking tongue 21 extends out or retracts into the first lock hole 11, so as to switch the anti-locking tongue 21 between the anti-locking state and the unlocking state.

[0049] In this way, the driving motor 31 and the inner handle seat 40 both control the first gear 32, and both transmit the rack portion 211 through the first gear 32 to control the movement of the anti-locking tongue 21. In this way, only one rack is needed to cooperate with the inner handle seat 40 and the driving motor 31, so that the transmission structure between the driving motor 31, the inner handle seat 40 and the rack is simpler.

[0050] In some embodiments, the circumferential surface of the inner handle seat 40 is provided with an abutting protrusion 42, the second gear 41 is rotatably sleeved on the inner handle seat 40, and the inner circle of the second gear 41 is provided with a notch 411, the abutting protrusion 42 is located in the notch 411, and the width of the notch 411 along the circumferential direction of the inner handle seat 40 is greater than the width of the abutting protrusion 42. The abutting protrusion 42 can move in the notch 411 through the rotation of the inner handle seat 40, or abut against the edge of the notch 411.

[0051] Specifically, when the driving device 30 drives the anti-locking tongue 21 to change between the anti-locking state and the unlocking state, the driving motor 31 drives the first gear 32 to rotate, and the first gear 32 drives the rack portion 211 to move, and at the same time drives the second gear 41 to rotate. However, at this time, when the second gear 41 rotates, the notch 41 follows the movement of the second gear 41. However, since the width of the notch 41 along the circumferential direction of the inner handle seat 40 is greater than the width of the abutting protrusion 42, the edge of the notch 41 will be separated from the abutting protrusion 42, so that the inner handle seat 40 does not rotate together with the second gear 41, and the inner door handle installed on the inner handle seat 40 will not rotate and remain in the initial position.

[0052] In some embodiments, the driving device 30 includes a third gear 33, which is transmission-connected to the driving motor 31 and is coaxial with the first gear 32 and can rotate relative to it. The third gear 33 is provided with two spaced-apart first abutment portions 331 in the circumferential direction, and the first gear 32 is provided with a second abutment portion 321 extending between the two first abutment portions 331.

[0053] Specifically, when locking or unlocking the door through the inner door handle, the second gear 41 rotates to drive the first gear 32 to rotate, and the first gear 32 rotates to drive the rack portion 211 to move. At this time, when the first gear 32 rotates, the second abutment portion 321 moves between the two spaced first abutment portions 331, and the third gear 33 and the rotating shaft of the drive motor 31 do not rotate. In this way, when the door is opened by the handle, the states of the third gear 33 and the drive motor 31 remain unchanged, and the drive device 30 is not affected.

[0054] In some embodiments, the lock housing 10 is provided with a third lock hole 15, and the lock tongue assembly 20 further includes a cross oblique tongue 22, a limiting mechanism 23 and a second elastic member 24. The cross oblique tongue 22 is movably mounted on the lock housing 10, and the second elastic member 24 connects the lock housing 10 and the cross oblique tongue 22, and has elastic deformation for driving the cross oblique tongue 22 to extend out of the third lock hole 15. The limiting mechanism 23 has a limiting member 233 movably mounted in the lock housing 10, and the limiting member 233 has a limiting state and an avoidance state. In the limiting state, the limiting member 233 is located on the side of the cross oblique tongue 22 away from the third lock hole 15 to limit the cross oblique tongue 22 from retracting into the third lock hole 15. In the avoidance state, the limiting member 233 is spaced apart from the cross oblique tongue 22.

[0055] Specifically, after locking the door, the reverse lock tongue 21 extends out of the reverse lock tongue 21 into the door frame, and the cross oblique tongue 22 extends out of the oblique tongue hole. The limiting member 233 is in the limiting state to limit the cross oblique tongue 22. When opening the door, the reverse lock tongue 21 is retracted into the lock shell 10, and the limiting member 233 moves to the avoidance position and is spaced apart from the cross oblique tongue 22, so that the cross oblique tongue 22 can be retracted into the lock shell 10 under the action of external force. In this way, the user can directly move the door panel so that the cross oblique tongue 22 contacts the door frame, and the cross oblique tongue 22 is retracted into the lock shell 10 under the pressure of the door frame. Compared with the traditional ordinary oblique tongue, when the limiting member 233 limits the cross oblique tongue 22, the external force cannot squeeze the cross oblique tongue 22 into the lock shell 10. This can prevent illegal elements from prying the lock by squeezing the cross oblique tongue 22, thereby improving the safety of the electronic lock body.

[0056] In some embodiments, the limiting mechanism 23 includes an unlocking paddle 231 and a fourth gear 232. The fourth gear 232 is rotatably mounted on the inner handle seat 40 and is coaxial with and spaced apart from the second gear 41. The fourth gear 232 is meshed with the third gear 33 and is transmission-connected to the limiting member 233 through the unlocking paddle 231 to drive the limiting member 233 to move from the limiting state to the avoidance state.

[0057] Specifically, when the driving device 30 drives the anti-locking tongue 21 to unlock, the third gear 33 drives the fourth gear 232 to move and rotate, so that the fourth gear 232 drives the unlocking paddle 231 to move, and when the unlocking paddle 231 moves, it drives the limiting member 233 to move from the limiting state to the avoiding state, so that the user can directly move the door, and the cross-oblique tongue 22 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-oblique tongue 22 by the limiting member 233 while releasing the anti-lock, which is more convenient for the user to open the door without additionally controlling the limiting member 233.

[0058] Further, the unlocking paddle 231 is arranged between the fourth gear 232 and the limiting member 233, and can move in the direction in which the fourth gear 232 and the limiting member 233 face each other. The unlocking paddle 231 is provided with a first toggle portion 2311 at one end close to the fourth gear 232, and a second toggle portion 2312 at one end close to the limiting member 233. The fourth gear 232 is provided with a second matching portion 2321 matching with the first toggle portion 2311, and the limiting member 233 is provided with a third matching portion 2333 matching with the second toggle portion 2312. When the reverse lock is released by the driving device 30, the fourth gear 232 is driven to rotate by the third gear 33, and at the same time, the second matching portion 2321 toggle the unlocking paddle 231 to move in the direction close to the fourth gear 232, so that the second toggle portion 2312 toggle the third matching portion 2333, so that the limiting member 233 moves from the limiting state to the avoiding state, and the cross-oblique tongue 22 can be retracted into the lock housing 10. In this way, the transmission structure between the fourth gear 232 and the unlocking paddle 231 is relatively simple.

[0059] In some embodiments, the inner handle seat 40 is in transmission connection with the unlocking paddle 231 , and the inner handle seat 40 drives the limiting member 233 to move from the limiting state to the avoiding state when moving along the unlocking direction.

[0060] Specifically, when the anti-lock bolt 21 is unlocked by the inner door handle, the inner handle seat 40 drives the unlocking paddle 231 to move, and the unlocking paddle 231 drives the limiting member 233 to move from the limiting state to the avoiding state, so that the user can directly move the door to make the cross-oblique bolt 22 retract into the lock housing 10 after contacting the door frame. In this way, the inner handle seat 40 releases the anti-lock and also releases the limiting member 233 from the cross-oblique bolt 22, which is more convenient for the user to open the door without additionally controlling the limiting member 233.

[0061] Furthermore, the inner handle seat 40 is provided with a third toggle portion 44 matched with the first toggle portion 2311. When the handle is used to release the reverse lock, the third toggle portion 44 toggle the unlocking paddle 231 to move toward the direction close to the fourth gear 232, so that the second toggle portion 2312 toggle the third matching portion 2333, so that the limiting member 233 moves from the limiting state to the avoiding state, and the cross-oblique tongue 22 can be retracted into the lock housing 10. In this way, the transmission structure between the fourth gear 232 and the unlocking paddle 231 is relatively simple.

[0062] In some embodiments, the limiting member 233 has a limiting portion 2331 and a first matching portion 2332. In the limiting state, the limiting portion 2331 is limited to the rear side of the cross latch 22. A third abutting portion 511 is provided at the rear end of the safety latch 51. The third abutting portion 511 is located on the side of the first matching portion 2332 away from the second lock hole 12, so that when the safety latch 51 extends out of the second lock hole 12, the third abutting portion 511 drives the limiting member 233 to move from the limiting state to the avoidance state by abutting the first matching portion 2332.

[0063] Specifically, when the door is opened, the first elastic member 53 pushes the safety latch 51 to extend out of the second lock hole 12, and at the same time the third abutting portion 511 abuts against the first matching portion 2332, driving the limiting member 233 to move, so that the limiting member 233 moves from the limiting state to the avoiding state, so that the cross latch 22 can be compressed back into the lock shell 10 by external squeezing. In this way, after the door is opened, the cross latch 22 can move freely. Even if the cross latch 22 or the safety latch 51 is accidentally touched, it will pop out again. This makes it convenient for the user to close the door directly after the door opening is completed. The cross latch 22 and the safety latch 51 will retract into the lock shell 10 when they touch the door frame. After the door is closed, the cross latch 22 extends out of the lock shell 10 to the door frame, and the safety latch 51 retracts into the lock shell 10 so that the cross latch 22 cannot be retracted into the lock shell 10 to complete the locking.

[0064] In some embodiments, the safety latch bolt 51 is located on the side of the cross latch bolt 22 away from the anti-lock bolt 21. Specifically, the driving device 30 and the inner handle seat 40 need to be transmission-connected with the anti-lock bolt 21 and the cross latch bolt 22. In this way, the cross latch bolt 22 is arranged on the side of the cross latch bolt 22 away from the anti-lock bolt 21, which can make the linkage between the driving device 30 and the inner handle seat 40 and the anti-lock bolt 21 and the cross latch bolt 22 more compact, and does not affect the setting of the limit plate at the position corresponding to the safety latch bolt 51 and the cross latch bolt 22.

[0065] In some embodiments, a second sensor and a third sensor are provided in the lock housing 10, and both the second sensor and the third sensor are connected to the electric control device. When the driving device 30 drives the anti-locking tongue 21 to move, when the anti-locking tongue 21 is in the anti-locking state, the second sensor is triggered, and when the anti-locking tongue 21 is in the unlocking state, the third sensor is triggered. Specifically, when the anti-locking tongue 21 is driven by the driving motor 31 to anti-lock or open the door, the position of the anti-locking tongue 21 can be detected, so that it can be ensured that the anti-locking tongue 21 moves to the specified position under the drive of the driving device 30.

[0066] In some embodiments, the anti-locking tongue 21 includes two locking tongues and a push rod. The push rod is movably installed in the lock housing 10. The two locking tongues are provided on the push rod, and the rack portion 211 is provided on the push rod. Specifically, compared with the anti-locking tongue 21 having one locking tongue, the anti-locking tongue 21 having two locking tongues has higher strength and better safety after the door is locked.

[0067] In some embodiments, the push rod and the two locking tongues are integrally formed. Specifically, this is more convenient when forming the anti-locking tongue 21, and the integrally formed anti-locking tongue 21 has higher strength.

[0068] In some embodiments, the anti-locking tongue 21 is provided with a first guiding convex portion 212, and the lock housing 10 is provided with a first guiding groove 13. The first guiding groove 13 extends along the extending direction of the rack portion 211. The anti-locking tongue 21 is installed in the first guiding groove 13 through the first guiding convex portion 212. Specifically, the structure of forming the first guiding groove 13 in the lock housing 10 and installing the anti-locking tongue 21 in the first guiding groove 13 through the first guiding convex portion 212 is relatively simple, and there is no need to additionally provide an installation structure in the lock housing 10 to install the anti-locking tongue 21.

[0069] In some embodiments, the lock housing 10 is provided with a second guiding groove 14, and the cross-shaped oblique tongue 22 is provided with a second guiding convex portion 221. The cross-shaped oblique tongue 22 is installed in the second guiding groove 14 through the second guiding convex portion 221. Specifically, by providing the second guiding convex portion 221 and the second guiding groove 14 to install the cross-shaped oblique tongue 22, the structure is relatively simple, and the movement of the cross-shaped oblique tongue 22 is relatively stable.

[0070] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
