Description

Technical Field

[0001] The utility model relates to the technical field of electronic locks, and particularly relates to an electronic lock body. Background Art

[0002] After a user inputs an opening instruction, a motor of an intelligent electronic lock can drive parts inside the lock body to move for automatic unlocking. Some anti-theft locks on the market currently have a structure in which a cross-shaped inclined tongue and a limiting member cooperate to lock the door. After the door is closed, the limiting member abuts against one end of the cross-shaped inclined tongue located inside the lock case, so that the limiting member cannot retract into the lock case under the action of an external force, which can prevent criminals from inserting a card into the door gap to pry the door. However, after the door is opened, if the cross-shaped inclined tongue is accidentally pressed into the lock body and then ejected, the limiting member will abut against the rear end of the cross-shaped inclined tongue for limiting. If the user wants to open the door again, they need to first release the limitation of the limiting member, which is rather troublesome to operate and results in a poor user experience.

[0033] The present utility model provides an electronic lock body.

[0034] In the embodiments of the present utility model, as Figures 1 to 6As shown, the electronic lock body includes a lock shell 10, a lock tongue assembly 20, a limiting mechanism 30, a safety latch bolt 40 and a lock core 50; the lock shell 10 is provided with a first through hole 11 and a second through hole 12; the lock tongue assembly 20 includes a cross latch bolt 21 and a first elastic member 22, the cross latch bolt 21 is movably mounted on the lock shell 10, the first elastic member 22 connects the lock shell 10 and the cross latch bolt 21, and has elastic deformation to drive the cross latch bolt 21 to extend out of the first through hole 11; the limiting mechanism 30 includes a limiting member 31 and a second elastic member 32, the limiting member 31 has a limiting position and an avoidance position, in the limiting position, the limiting member 31 is located on the side of the cross latch bolt 21 away from the first through hole 11 to limit the cross latch bolt 21 from retracting into the first through hole 11, in the avoidance position, the limiting member 31 is spaced from the cross latch 21, the second elastic member 32 has elastic deformation that drives the limiting member 31 to move from the avoidance position to the limit position, the safety latch 40 is movably installed at the second through hole 12, and is connected to the third elastic member 41 provided in the lock housing 10, the third elastic member 41 has elastic deformation that drives the safety latch 40 to extend from the second through hole 12, the safety latch 40 retracts into the second through hole 12 when the door is closed, the safety latch 40 is linked with the limiting member 31, so as to drive the limiting member 31 to move to the avoidance position when the third elastic member 41 drives the safety latch 40 to extend from the second through hole 12; the lock core 50 is provided in the lock housing 10, and the shift fork 51 of the lock core 50 is transmission-connected with the limiting member 31, and is used to drive the limiting member 31 to move from the limit position to the avoidance position.

[0035] Specifically, when closing the door, the cross oblique tongue 21 is squeezed by the door frame and retracted into the first through hole 11. After the door is closed, the cross oblique tongue 21 extends from the first through hole 11 to the lock hole of the door frame and retracts into the second through hole 12. At the same time, the limiting member 31 moves from the avoidance position to the limiting position under the action of the second elastic member 32, limiting the cross oblique tongue 21, so that the cross oblique tongue 21 can no longer be retracted into the lock housing 10 under the action of external force. When the key is inserted into the lock cylinder 50 and rotated, the shift fork 51 rotates and drives the limit member 31 to move from the limit position to the avoidance position. Then the user moves the door panel so that the cross latch 21 is pressed into the first through hole 11 by the door frame. After the door is opened, the first elastic member 22 drives the cross latch 21 to extend out of the first through hole 11, and the third elastic member 41 drives the safety latch 40 to extend out of the second through hole 12. At the same time, the safety latch 40 drives the limit member 31 to move to the avoidance position, so that the cross latch 21 can be easily retracted into the first through hole 11.

[0036] In the technical solution of the present utility model, a first through hole 11 is provided in the lock case 10, a cross-shaped latch 21 is movably installed in the lock case 10, and a first elastic member 22 is provided to drive the cross-shaped latch 21 to extend out of the first through hole 11. In addition, a movable limiting member 31 is provided in the lock case 10, and a second elastic member 32 is provided to drive the limiting member 31 to move from the avoiding position to the limiting position. After closing the door, the limiting member is located on the side of the cross-shaped latch 21 away from the first through hole 11 and restricts the cross-shaped latch 21 from retracting into the first through hole 11. In addition, a third elastic member 41 and a safety latch 40 are provided. In the closed-door state, the safety latch 40 is located in the lock case 10. In the open-door state, the third elastic member 41 drives the safety latch 40 to extend out of the lock case 10 through the second through hole 12. At the same time, the safety latch 40 is linked to the limiting member 31 to drive the limiting member 31 to move to the avoiding position, so that the cross-shaped latch 21 can be retracted into the first through hole 11 under external extrusion.

[0037] When closing the door, the safety latch 40 retracts into the second through hole 12, the cross-shaped latch 21 extends out of the first through hole 11 to the door frame, and the limiting member 31 limits the cross-shaped latch 21 in the lock case 10, so that the cross-shaped latch 21 cannot be retracted into the first through hole 11 under external force, effectively preventing criminals from prying the door.

[0038] After inserting the key into the lock core 50 and the fork 51 drives the limiting member 31 to move to the avoiding position to complete opening the door, the first elastic member 22 drives the cross-shaped latch 21 to extend out of the first through hole 11, and the third elastic member 41 drives the safety latch 40 to extend out of the second through hole 12. At the same time, the safety latch 40 drives the limiting member 31 to move to the avoiding position, so that the cross-shaped latch 21 can be retracted into the first through hole 11 under the action of external force. In this way, even if the cross-shaped latch 21 is accidentally retracted into the first through hole 11, the limiting member 31 still remains in the avoiding position, which is convenient for the user to close the door and avoids the situation that the cross-shaped latch 21 cannot be retracted into the first through hole 11 after being accidentally retracted into the first through hole 11 and then extended, providing a better user experience.

[0039] In some embodiments, a hook portion 42 is provided on the part of the safety latch 40 located in the lock case 10, and the limiting member 31 has an extension portion 312 extending towards the safety latch 40. The extension portion 312 is located on the side of the hook portion 42 facing the second through hole 12, so that when the safety latch 40 extends towards the second through hole 12, the hook portion 42 abuts against the extension portion 312 to drive the limiting member 31 to move from the limiting position to the avoiding position.

[0040] Specifically, when the first elastic member 22 pushes the safety inclined tongue 40 to extend from the second through hole 12, the extension portion 312 can be hooked by the hooking portion 42, so as to drive the limiting member 31 to rotate to the avoiding position, so as to ensure that the limiting member 31 can be held in the avoiding position in the open door state, so as to facilitate the user to close the door at any time (when the cross inclined tongue 21 abuts against the door frame but has not entered the corresponding lock hole during the closing process of the door, the cross inclined tongue 21 can move towards the inside of the lock case 10).

[0041] In some embodiments, the lock case 10 is provided with a rotatable inner door handle seat 60. The inner door handle seat 60 is used to connect with the inner door handle. The inner door handle seat 60 is in transmission connection with the limiting member 31, so as to drive the limiting member 31 to move from the limiting position to the avoiding position when the inner door handle seat 60 rotates along the unlocking direction. Specifically, the inner door handle seat 60 is installed with an inner door handle. When the user presses down the inner door handle, the inner door handle seat 60 rotates along the unlocking direction, so as to drive the limiting member 31 to move from the limiting position to the avoiding position, facilitating the user to open the door through the inner door handle inside the door.

[0042] In some embodiments, the lock case 10 is provided with a third through hole 13. The third through hole 13 is movably installed with a deadbolt 70. The inner door handle seat 60 is in transmission connection with the deadbolt 70, so as to drive the deadbolt 70 to retract into the third through hole 13 when the inner door handle seat 60 rotates along the unlocking direction, and drive the deadbolt 70 to extend out of the third through hole 13 when the inner door handle seat 60 rotates along the anti-lock direction. Specifically, in this way, when inside the door, the door can be anti-locked by lifting the door handle, improving the security of the door lock. Moreover, when pressing down the door handle, while driving the limiting member 31 to move from the limiting position to the avoiding position, the deadbolt 70 is also driven to retract into the third through hole 13. Compared with anti-locking by turning a knob or other means, the user operation is more convenient in this way.

[0043] In some embodiments, a driving assembly 80 is arranged inside the lock case 10. The driving assembly 80 includes a driving motor 81. The driving motor 81 is in transmission connection with the limiting member 31, at least for driving the limiting member 31 to move from the limiting position to the avoiding position. Specifically, in this way, the user can drive the limiting member 31 to move from the limiting position to the avoiding position through the driving motor 81, so as to facilitate the user to open the door. Moreover, a password module or a fingerprint module can be arranged on the door and connected to the driving motor 81, facilitating the user to open the door without a key. Further, a Bluetooth module or a wireless network module can also be arranged to connect to the driving motor 81, enabling the user to open the door remotely.

[0044] In some embodiments, the driving assembly 80 includes a driving motor 81 and a transmission gear 82. The driving motor 81 is used to drive the transmission gear 82 to rotate. The transmission gear 82 is arranged between the driving motor 81 and the limit member 31. The limit mechanism 30 includes a linkage member 33, which is movably installed in the lock shell 10. The linkage member 33 is at least partially spaced from the transmission gear 82 in the thickness direction of the lock shell 10. The linkage member 33 is provided with a first hook portion 331 and a second hook portion 332. The transmission gear 82 is provided with a first matching portion 821, and the first matching portion 821 is located in the first hook portion 331. The limit member 31 is provided with a second matching portion 311, and the second matching portion 311 is located in the second hook portion 332. When the transmission gear 82 rotates, the first matching portion 821 drives the first hook portion 331 to move in a direction away from the limit member 31, so that the second hook portion 311 moves the second matching portion 311, so that the limit member 31 moves to the avoidance position.

[0045] Specifically, the first hook portion 331 and the second hook portion 332 are arranged opposite to each other, and the side of the first hook portion 331 facing the second hook portion 332 is used to abut against the first matching portion 821, and the side of the second hook portion 332 facing the first hook portion 331 is used to abut against the second matching portion 311, and the second matching portion 311 and the rotation axis of the limiting member 31 are spaced apart in the moving direction of the cross-oblique tongue 21. In the closed state, the first hook portion 331 is located above the first matching portion 821, and when the anti-locking tongue 70 extends from the first tongue hole, the anti-locking tongue 70 is driven to retract into the first tongue hole by the driving motor 81, and the third gear can be driven to rotate, so that the first matching portion 821 abuts against the side of the first hook portion 331 facing the second hook portion 332, thereby pushing the linkage member 33 to move upward, and at this time, the second hook portion 332 hooks the second matching portion 311, thereby driving the limiting member 31 to rotate, so that the limiting member 31 moves from the limiting position to the avoidance position. When the anti-locking tongue 70 is retracted to the first tongue hole, the limiting member 31 moves to the avoidance position, so that unlocking can be achieved. This is that the linkage member 33 and the driving motor 81 are linked to the limiting member 31, and the structure is relatively simple.

[0046] In some embodiments, a driving assembly 80 is provided in the lock housing 10, and a driving motor 81 is transmission-connected with the anti-locking tongue 70, and is used to drive the anti-locking tongue 70 to extend out of the third through hole 13 or to retract into the third through hole 13. Specifically, when the door is opened by the driving motor 81, the driving motor 81 drives the limiter 31 from the limit position to the avoidance position, and also drives the anti-locking tongue 70 to retract into the third through hole 13, so that the situation of operating the limiter 31 and the anti-locking tongue 70 to unlock the door separately can be avoided.

[0047] Furthermore, the driving assembly 80 includes a first gear 83, which is in driving connection with the driving motor 81, and the anti-locking tongue 70 is provided with a rack portion 72, which extends along the moving direction of the anti-locking tongue 70. In this way, when the driving motor 81 rotates, the first gear 83 is driven to rotate, and the first gear 83 drives the rack portion 72 and the anti-locking tongue 70 to extend out of the third through hole 13 or retract into the third through hole 13, so as to switch the anti-locking tongue 70 between the anti-locking state and the unlocking state.

[0048] In some embodiments, a toggle member 14 is rotatably installed in the lock housing 10. The toggle member 14 has a first arm 141 extending toward the lock cylinder 50. The first arm 141 is arranged corresponding to the shift fork 51 of the lock cylinder 50, so that the shift fork 51 can push the first arm 141 to push the limit member 31 to move to the avoidance position. Specifically, the shift fork 51 can be rotated by a key, and the shift fork 51 pushes the first arm 141 to drive the limit member 31 to move from the limit position to the avoidance position. In this way, the toggle member 14 is arranged to link the shift fork 51 and the limit member 31, and the structure is relatively simple.

[0049] In some embodiments, a side of the anti-lock tongue 70 away from the third through hole 13 is provided with an abutment portion 71, and the toggle member 14 has a second arm 142 extending toward the anti-lock tongue 70, and the second arm 142 is located on the side of the abutment portion 71 facing the third through hole 13, so that the fork 51 can push the first arm 141 to drive the second arm 142 to move toward the abutment portion 71, thereby pushing the anti-lock tongue 70 to retract into the third through hole 13. Specifically, when the key rotates the fork 51, the fork 51 pushes the first arm 141 to drive the limiter 31 to move from the limit position to the avoidance position, while the second arm 142 pushes the abutment portion 71 to drive the anti-lock tongue 70 to retract into the third through hole 13, so that the anti-lock tongue 70 and the limiter 31 are driven to unlock at the same time by the key, which can avoid the situation where the limiter 31 and the anti-lock tongue 70 are operated separately to unlock.

[0050] In some embodiments, a mounting shaft 15 is provided in the lock housing 10, and the mounting shaft 15 extends in the thickness direction of the lock housing 10. The stopper 31 is in a sheet shape and is rotatably mounted on the mounting shaft 15. Specifically, by setting the stopper 31 in a sheet shape and mounting it on the mounting shaft 15, the thickness space occupied by the stopper 31 in the lock body is small, and the rotation structure of the stopper 31 is also relatively simple. Furthermore, the toggle member 14 is also mounted on the mounting shaft 15, so that the stopper 31 and the toggle member 14 share a mounting shaft 15, and no other rotation structure is required.

[0051] 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.
