[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 to 7 As shown, an embodiment provided by the present invention:

[0035] An unlocking device for an electronic lock, comprising:

[0036] A housing 1;

[0037] An electronic lock clutch 3, the electronic lock clutch 3 is arranged in the housing, and the electronic lock clutch 3 includes a first housing 31, a first push rod 35, a lock sleeve 36, and a lock core 34; the first push rod 35 and the lock sleeve 36 are sequentially sleeved in the first housing 31, and the first push rod 35 movably penetrates through the first housing 31. A first stop block 351 is arranged on the first push rod 35, and the first stop block 351 is arranged in the first housing 31. The first stop block 351 is used to limit the first push rod 35. The lock core 34 is sleeved in the lock sleeve 36, and the lock sleeve 36 is provided with a first push block corresponding to the first push rod 35; the first push rod 35 extends or retracts under the push of the lock core 34 and the lock sleeve 36.

[0038] A first limiting device, the first limiting device includes a first snap ring 37, a first return spring, and a first limiting member; the first snap ring 37, the first return spring 33, and the first limiting member 32 are sequentially sleeved on the first housing 31, and one end of the first return spring 33 is arranged on a limiting post 11 in the housing 1, and one end of the first limiting member 32 is arranged in the first return spring 33;

[0039] When a key is inserted into the lock cylinder 34 and the lock cylinder 34 is rotated by the key, the lock sleeve 36 moves upward. At the same time, the push rod of the lock sleeve 36 will push the first push rod 35 upward, so that one end of the first push rod 35 is pushed into the bolt connecting member of the door lock. Then, when the lock cylinder 34 is rotated forcefully again, the first housing 31, the first snap ring 37, the first return spring 33, and the first limiting member 32 will rotate accordingly, pulling the bolt connecting member back. At the same time, the door lock is opened, so that the door can be opened and people can enter. When the lock cylinder 34 is not rotated forcefully, the first housing 31, the first snap ring 37, the first push rod 35, the lock sleeve 36, and the lock cylinder 34 are reset under the elastic force of the first return spring 33, so that the manual opening of the door lock can be realized and the automatic reset of the electronic lock clutch 3 and the first limiting device can be realized;

[0040] The second limiting device 4, the second limiting device 4 includes a second snap ring 46, a first clamping block 44, a second return spring 42, and a second limiting member 41; the second snap ring 46, the first clamping block 44, the second return spring 42, and the second limiting member 41 are sequentially arranged on the first push rod 35, and the first clamping block 44 is fixedly connected to the first limiting member 32;

[0041] The driving device 2, the driving device 2 is correspondingly arranged in the housing 1, and the driving device 2 is used to limit the second limiting device 4;

[0042] When the driving device 2 does not limit the second limiting device 4, the second limiting member 41 can rotate freely. At the same time, the bolt connecting member sleeved therewith can be opened. After opening, the second limiting member 41 is reset by the second return spring 42; when the driving device 2 limits the second limiting device 4, the second limiting member 41 cannot rotate and the bolt connecting member cannot be opened;

[0043] In the above, when the manual opening of the door lock is realized, the second limiting device 4 can be used in combination with the first limiting device. The bolt connecting member is sleeved on the second limiting member 41. When one end of the first push rod 35 is pushed into the bolt connecting member of the door lock, the door can also be opened.

[0044] Furthermore, in order to realize the electronic drive to limit the second limiting member 41; the technical solution is as follows:

[0045] The driving device 2 includes a second housing 21, a motor 26, a rotating shaft 23, a transmission piece 24, a fixing rod 22, a first fixing block 27, and a second push rod 25; the second housing 21 is respectively provided with a receiving cavity corresponding to the motor 26, the fixing rod 22, and the second push rod 25; the rotating shaft 23 is sleeved on the driving shaft of the motor 26, the first fixing block 27 is sleeved on the fixing rod 22, one end of the transmission piece 24 is movably fixed on the first fixing block 27, the middle part of the transmission piece 24 is sleeved in the rotating shaft 23, and the other end of the transmission piece 24 is connected to the second push rod 25;

[0046] When the motor 26 rotates forward or backward, the rotating shaft 23 rotates forward or backward. While the rotating shaft 23 rotates forward or backward, the transmission piece 24 rotates upward or downward, so that the second push rod 25 moves upward or downward. The second push rod 25 then limits or opens the second limiting member 41, thereby realizing the electronic driving of the electronic door lock.

[0047] In order to further realize the effective transmission or reset of the transmission piece 24, the transmission piece 24 is provided as a spring piece, and the spring piece is provided as an inverted V-shaped structure;

[0048] One end of the transmission piece 24 is fixed in the fixing rod 22, the middle part of the transmission piece 24 is stuck in the rotating shaft 23, and the other end of the transmission piece 24 is connected to the second push rod 25. When the motor 26 rotates forward or backward, since one end of the transmission piece 24 is fixed to the fixing rod 22 and cannot rotate, under the action of the rotating shaft 23, the other end of the transmission piece 24 will deform, so that the second push rod 25 can effectively move downward. When the motor 26 rotates in the other direction, the spring piece will return to its original shape, so that the second push rod 25 can be reset. Thus, through simple physical elastic changes, the rotation and reset functions can be realized.

[0049] Furthermore, in order to better fix one end of the transmission piece 24 and prevent it from falling off, the technical solution is as follows:

[0050] The first fixing block 27 is provided with a clamping groove corresponding to one end of the spring piece for limiting one end of the spring piece.

[0051] Furthermore, in order to enable the transmission piece 24 to rotate flexibly with the rotating shaft 23, the technical solution is as follows:

[0052] The rotating shaft 23 is provided as a spiral structure. This solution realizes the upward or downward movement of the transmission piece 24 through the forward and reverse settings of the threads.

[0053] Furthermore, in order to prevent the transmission piece 24 from breaking and to enable better reset, the technical solution is as follows:

[0054] A third return spring is provided on the fixed rod 22 corresponding to the elastic piece. The third return spring is sleeved on the fixed rod 22, and the first fixing block 27 is sleeved on the third return spring 28. Under the action of the third return spring 28, the elastic piece will be more elastic, and through the action of the third return spring 28, it can protect the elastic piece from being broken due to excessive force from the motor 26, thus playing a buffering role and also a resetting role.

[0055] Further, in order to enable the second push rod 25 to be pushed better and more flexibly, the technical solution is as follows:

[0056] One end of the second push rod 25 is provided with an arc-shaped structure.

[0057] Further, in order to enable the second limiting device 4 to cooperate with the electronic lock clutch 3 and the second limiting device 4 for use; the technical solution is as follows:

[0058] The first clamping block 44 is provided with a receiving groove, and the receiving groove is provided with a first through hole 442. The first clamping block 44 is sleeved on the first push rod 35 through the first through hole 442; two fixing columns 443 are provided at the bottom end of the first clamping block 44 corresponding to the first limiting member 32, and the first clamping block 44 is fixedly connected to the first limiting member 32 through the two fixing columns 443.

[0059] Further, in order to cooperate with the second push rod 25, the second limiting member 41 can be better and effectively limited. The technical solution is as follows:

[0060] A limiting through hole 441 is provided on one side of the first clamping block 44, and a movable limiting telescopic rod 45 is sleeved in the limiting through hole 441. One end of the limiting telescopic rod 45 is arranged corresponding to the arc-shaped structure of one end of the second push rod 25, and the other end of the limiting telescopic rod 45 is used to limit the second limiting member 41.

[0061] Further, in order to enable the second limiting member 41 to be reset and limited; the technical solution is as follows:

[0062] A protruding limiting block 43 is provided at the top end of the first clamping block 44. The second return spring 42 and the second limiting member 41 are sleeved in the receiving groove of the first clamping block 44, and one end of the second return spring 42 is clamped on the limiting block 43. The second return spring 42 is used to reset the second limiting member 41.

[0063] The working principle of the present invention is as follows:

[0064] (1) When inserting a key into the lock core 34, rotate the lock core 34 with the key, then the lock sleeve 36 moves upward. At the same time, the push rod of the lock sleeve 36 will push the first push rod 35 upward, so as to push one end of the first push rod 35 into the bolt connecting piece of the door lock. Then, when rotating the lock core 34 forcefully again, the first housing 31, the first snap ring 37, the first return spring 33, and the first limiting member 32 rotate accordingly, pulling the bolt connecting piece back, and at the same time opening the door lock, so that the door can be opened and people can enter.

[0065] (2) When not rotating the lock core 34 forcefully, the first housing 31, the first snap ring 37, the first push rod 35, the lock sleeve 36, and the lock core 34 reset under the elastic force of the first return spring 33, so that the manual opening of the door lock can be realized and the automatic reset of the electronic lock clutch 3 and the first limiting device can be achieved.

[0066] (3) When the motor 26 rotates forward or backward, the rotating shaft 23 rotates forward or backward. While the rotating shaft 23 rotates forward or backward, the transmission piece 24 rotates upward or downward, so that the second push rod 25 moves upward or downward. The second push rod 25 then limits or opens the second limiting member 41, thus realizing the electronic drive of the electronic door lock.

[0067] (4) When manually opening the door lock, the second limiting device 4 can be used in combination with the first limiting device. The bolt connecting piece is sleeved on the second limiting member 41. When one end of the first push rod 35 is pushed into the bolt connecting piece of the door lock, the door can also be opened.

[0068] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
