Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Referring to fig. 1 to 9, the utility model discloses a drive assembly for electronic lock, including lock core 100, lock core 100 rotates in order to unblank or lock, be equipped with first locking piece 110 on lock core 100, still include:

a fixing plate 400;

the rotating block 200 can rotate around a first rotating shaft relative to the fixing plate 400, the rotating block 200 is provided with a first connecting portion 201 and a second connecting portion 202, the first connecting portion 201 is provided with a second locking member 210, the second locking member 210 is abutted to or separated from the first locking member 110 to lock or unlock the rotation of the lock cylinder 100, and the rotating block 200 is rotated to make the second locking member 210 abutted to or separated from the first locking member 110;

and a sliding block 300 slidably disposed on the fixing plate 400, wherein the sliding block 300 is slid to abut against the second connecting portion 202 and drive the rotating block 200 to rotate, and a distance from the first connecting portion 201 to the first rotating shaft is smaller than a distance from the second connecting portion 202 to the first rotating shaft.

Specifically, according to the present application, the sliding block 300 slides to abut against the rotating block 200 and drive the rotating block 200 to rotate, and the rotating block 200 can drive the second locking member 210 to rotate by a small angle in the rotating process, so that the first locking member 110 and the second locking member 210 are separated or abutted, and finally, the lock core 100 is unlocked or locked by rotating.

In this process, the sliding motion of the sliding block 300 is converted into the rotation of the rotating block 200, and then the rotation of the rotating block 200 drives the second locking member 210 to rotate at a small angle. Compared with a mode of directly driving the second locking piece 210 to move through the motor, in the process of converting the sliding of the sliding block 300 into the rotating motion mode of the rotating block 200, because the distance from the first connecting part 201 to the first rotating shaft is smaller than the distance from the second connecting part 202 to the first rotating shaft, the moving distance of the second locking piece 210 is smaller than the sliding distance of the sliding block 300, and further, the moving distance of the second locking piece 210 is reduced through the conversion of the motion mode, so that the motor can accurately control the motion of the second locking piece 210 in a shorter distance in a larger rotating angle range, the requirement on the motor is reduced, and meanwhile, the phenomenon that the lock cylinder 100 is damaged due to the fact that the moving distance of the second locking piece 210 is too large is avoided.

Further, the first connecting portion 201 and the second connecting portion 202 are respectively located at two ends of the rotating block 200, and the first rotating shaft is located at one end of the rotating block 200 close to the first connecting portion 201.

Specifically, the sliding block 300 pushes the second connecting portion 202 to move, so that the rotating block 200 rotates around the first rotating shaft, and simultaneously drives the second locking member 210 to rotate around the first rotating shaft; the distance from the first connecting portion 201 to the first rotating shaft is zero, which further reduces the moving distance of the second locking member 210.

More specifically, the second lock member 210 moves in a rotational manner, rather than a conventional linear movement, so that the second lock member 210 is effectively prevented from impacting the lock cylinder 100.

Further, the first lock member 110 has a first guide surface 112 and an abutment surface 111, and the thickness of the first guide surface 112 is gradually increased from the first guide surface 112 toward the abutment surface 111;

the second locking member 210 includes a connecting section and an abutting section, one end of the connecting section is fixedly connected with the first connecting portion 201, the other end of the connecting section is fixedly connected with the abutting section, and one end of the abutting section, which is far away from the connecting section, is abutted to or separated from the abutting surface 111; the connecting section is cylindrically arranged and the cross-sectional area of the abutment section is gradually reduced from the connecting section towards the abutment section line of defense to form a second guiding surface 211.

And a pre-tightening spring 220 is further arranged, and the pre-tightening spring 220 is abutted against one side of the rotating block 200 far away from the second connecting part 202. Set up pretension spring 220, under the locking state, pretension spring 220 is in the state of compressed to this provides the pretension and guarantees that first locking piece 110 is all the time with second locking piece 210 looks butt, the dynamics of reinforcing locking. When the sliding block 300 retracts, the rotating block 200 can be driven to rotate, and the first locking piece 110 and the second locking piece 210 are abutted again to realize secondary locking.

In the locked state, the abutting surface 111 abuts against the abutting section, and the rotation of the lock cylinder 100 is locked; after the second locking piece 210 rotates a certain angle, the abutting surface 111 is separated from the abutting section, and the lock core 100 rotates to realize unlocking of the lock.

Specifically, as shown in fig. 3 to 4, after the first locking member 110 and the second locking member 210 are separated, the sliding block 300 is retracted, the rotating block 200 is returned by the biasing spring 220, and the abutting section slides on the first guide surface 112; the second guide surface 211 abuts against the side wall of the key cylinder 100 as the key cylinder 100 is rotated; the lock core 100 continues to rotate, the abutting section slides into the first guide surface 112 from the end with the smaller thickness, and after the abutting section slides out from the end with the larger thickness in the first guide surface 112, the abutting section and the abutting surface 111 abut against each other again to achieve locking.

In this process, the sliding block 300 can be retracted at the moment when the abutting surface 111 and the abutting section are separated, and the rotating block 200 automatically completes the secondary locking under the action of the pre-tightening spring 220.

The first guide surface 112 and the second guide surface 211 are provided to make the relative sliding of the first guide surface 112 and the second guide surface 211 smoother and to prevent the first locking member 110 and the second locking member 210 from getting caught during the relative sliding.

Further, the slider 300 is disposed at one side of the rotation block 200, and the second locking member 210 is disposed at the other side of the rotation block 200.

Specifically, as shown in fig. 3, the second locking member 210 and the sliding block 300 are respectively located on different sides of the rotating block 200, so that the second locking member 210 and the first locking member 110 are separated from abutment during the process of pushing the rotating block 200 to rotate by the sliding block 300. That is, even if the sliding block 300 pushes the rotating block 200 to rotate by an excessively large angle, the second locking member 210 will not collide with the first locking member 110, thereby preventing the lock cylinder 100 from being damaged.

Further, the slider further comprises a limiting block 410, a first limiting groove 411 is formed in the limiting block 410, and the sliding block 300 is slidably arranged in the first limiting groove 411.

Further, the device also comprises a driving disc 510, wherein the driving disc 510 rotates around a second rotating shaft, and a driving column 511 is arranged on the driving disc 510 and deviates from the second rotating shaft;

the sliding block 300 is provided with a second limiting groove 310, and the driving column 511 is slidably disposed in the second limiting groove 310.

The device further comprises a driving motor 500, wherein the driving motor 500 is used for driving the driving disc 510 to rotate.

Specifically, since the driving column 511 deviates from the second rotating shaft, when the driving disc 510 rotates, the driving column 511 can be driven to slide in the second limiting groove 310, and simultaneously, the sliding block 300 can be driven to slide in the first limiting groove 411, so as to drive the rotating block 200 to rotate, thereby separating the first locking piece 110 from the second locking piece 210.

Furthermore, the rotation path of the driving column 511 is a circle, and the center of the circle is located at the second rotating shaft, so that the rotation path is divided into an upper semicircle and a lower semicircle. Assuming that the driving column 511 is capable of driving the sliding block 300 to move toward the rotating block 200 when rotating in the upper semicircle, so as to push the rotating block 200 to rotate and separate the first locking member 110 and the second locking member 210; when the driving column 511 rotates in the lower semicircle, the sliding block 300 is driven to slide reversely, so that the rotating block 200 rotates reversely to make the first locking member 110 and the second locking member 210 abut against each other to realize secondary locking.

That is to say, the driving motor 500 drives the sliding column to rotate along the same direction, so that the reciprocating motion of one stroke of the sliding block 300 can be realized, the unlocking and locking processes can be realized, the rotating direction of the driving motor 500 does not need to be changed in the unlocking and locking processes, and the service life of the driving motor 500 is further prolonged.

Meanwhile, after the first locking piece 110 and the second locking piece 210 are separated, the driving motor 500 does not need to stop rotating, the lockset can be locked again by continuously rotating, the rotating range of the driving motor 500 in one-time starting and stopping is further increased, the problem that the driving motor 500 cannot be accurately controlled to start and stop in a small range is solved, the requirement on the driving motor 500 is lowered, and the lockset can be realized by using a common motor, so that the cost is lowered.

Further, the length direction of the first limiting groove 411 is perpendicular to the length direction of the second limiting groove 310.
