Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present application, where the contrary is not intended, the use of directional words such as "upper, lower, top and bottom" is generally with respect to the orientation shown in the drawings, or with respect to the component itself in the vertical, perpendicular or gravitational direction; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.

In order to solve the poor problem of performance of electronic door lock among the prior art, this application provides an electronic door lock.

As shown in fig. 1 to 18, the electronic door lock of the present application includes a lock body 10, a locking rod 20 and a locking assembly 30, at least a portion of the locking rod 20 is movably disposed in the lock body 10, the locking rod 20 has a sliding slot 21, and the locking rod 20 has a locking position and an unlocking position when moving along an axial direction thereof, and the sliding slot 21 has a first holding position 215 and a second holding position 216 for holding the locking rod 20 at the locking position and the unlocking position; the locking assembly 30 is movably disposed within the lock body 10, the locking assembly 30 including: the locking head 31 is always positioned in the sliding groove 21, when the locking rod 20 is in the locking position, the locking head 31 is positioned at one end of the sliding groove 21 in the axial direction of the locking rod 20, when the locking rod 20 is in the unlocking position, the locking head 31 is positioned at the other end rotating part 32 of the sliding groove 21 in the axial direction of the locking rod 20, the rotating part 32 is connected with one end, away from the locking rod 20, of the locking head 31 and can drive the locking head 31 to rotate, when the locking head 31 is positioned at any end of the sliding groove 21 in the axial direction of the locking rod 20, the locking head 31 is clamped with the sliding groove 21, and the rotating part 32 idles and the locking head 31 keeps still.

With the electronic door lock of the above-described configuration, when the locking lever 20 is switched between the locking position and the unlocking position, the locking head 31 of the locking unit 30 is switched at both ends of the slide groove 21 of the locking lever 20, thereby ensuring that the locking lever 20 is held at the locking position or the unlocking position. When the position of the locking head 31 relative to the sliding chute 21 changes, the rotating part 32 can drive the locking head 31 to rotate, and because the rotating part 32 can idle when the locking head 31 is positioned at the two ends of the sliding chute 21 and the locking head 31 is kept still, the rotating part 32 can protect the rotating part 32 per se. Therefore, the problem of poor use performance of electronic lock among the prior art has been solved effectively to electronic lock in this application.

As shown in fig. 3, the rotating portion 32 includes a rotating body 321 and a restraining structure 322. The locking head 31 is connected with the rotating body 321 through the constraint structure 322, when the locking head 31 is not pressed by external force, the locking head 31 is constrained by the constraint structure 322, so that the rotating body 321 drives the constraint structure 322 and the locking head 31 to synchronously rotate, when the locking head 31 is pressed by the external force of the chute 21, the constraint structure 322 releases the constraint on the locking head 31, and the rotating body 321 only drives the constraint structure 322 to rotate. Through the arrangement, when the locking head 31 cannot rotate under the influence of external force, the constraint structure 322 is in contact with the locking head 31 to realize the idle rotation of the rotating body 321, and the phenomenon that the rotating body 321 is blocked can be effectively avoided. When the rotating body 321 can rotate without being subjected to an external force, the locking head 31 and the rotating body 321 can be driven by the rotating body 321 to rotate together with the locking head 31 under the action of the constraint structure 322.

It should be noted that when the locking heads 31 are located at both ends of the slide groove 21, the locking heads 31 can act on the locking lever 20 so that the locking lever 20 is held at the locking position or the unlocking position. Also, in this process, the locking rod 20 can also limit the position of the locking head 31. Therefore, when the latching lever 20 is held at the latching position or the unlatching position, the locking head 31 is held by the latching lever 20, so that the rotating portion 32 is idly rotated.

As shown in fig. 8, an end of the locking head 31 away from the locking rod 20 is provided with an accommodating groove 313, and the rotating body 321 includes a driving motor 3211 and a clutch inner 3212. The driving motor 3211 is in driving connection with the clutch inner ring 3212, the clutch inner ring 3212 is disposed in the accommodating groove 313, and the constraining structure 322 is disposed between the locking head 31 and the clutch inner ring 3212. Through the arrangement, when the locking head 31 is not pressed and can rotate, the driving motor 3211 drives the clutch inner ring 3212 to rotate, and under the action of the constraint structure 322, the clutch inner ring 3212 drives the locking head 31 to rotate. When the locking head 31 cannot rotate, the driving motor 3211 drives the clutch inner ring 3212 to rotate in the accommodating groove 313, and at this time, the constraint structure 322 rotates together with the clutch inner ring 3212.

Specifically, the constraint structure 322 includes a plurality of sets of reset components arranged at intervals along the circumferential direction of the clutch inner ring 3212, each set of reset components includes a spring 3221 and a steel ball 3222 abutted against each other, the outer circumferential wall of the clutch inner ring 3212 has a circular groove 3213 for positioning the spring 3221, the surface of the locking head 31 facing one side of the clutch inner ring 3212 has a locking groove 311, and the steel ball 3222 can extend into the locking groove 311 under the action of the spring 3221. By this arrangement, one end of the spring 3221 away from the steel ball 3222 can extend into the circular groove 3213, and one end of the spring 3221 close to the steel ball 3222 extends from the circular groove 3213 to the surface of the locking head 31 on the side facing the clutch inner ring 3212. When the locking head 31 cannot rotate, the clutch inner ring 3212 can drive the spring 3221 and the steel ball 3222 to rotate in the accommodating groove 313 under the action of the driving motor 3211. When the locking head 31 can rotate, a part of the steel balls 3222 enters the locking groove 311 along with the rotation of the clutch inner ring 3212, and drives the locking head 31 to rotate together. In addition, a part of the steel balls 3222 is always kept in the locking groove 311 during the rotation of the locking head 31, so that the locking head 31 and the clutch inner ring 3212 can be ensured to rotate synchronously.

As shown in fig. 8, in one embodiment of the present application, the reset assembly has three sets, and the outer peripheral wall of the clutch inner ring 3212 has three circular grooves 3213 uniformly distributed, and the locking head 31 also has three locking grooves 311.

It should be noted that, when the locking head 31 cannot rotate and the clutch inner ring 3212 drives the constraint structure 322 to rotate in the accommodating groove 313, the steel balls 3222 continuously enter and leave the locking groove 311 in the process. Therefore, in order to reduce the resistance of the rotating portion 32 during idling, the locking groove 311 needs to be an arc-shaped groove, i.e., the locking groove 311 and the surface of the locking head 31 facing the clutch inner 3212 are smoothly transited.

Specifically, the locking head 31 includes a body portion 312 and a projection portion 314. The body portion 312 has a receiving groove 313 for receiving the rotating portion 32; the protrusion 314 is disposed at an end of the main body 312 away from the rotating portion 32 and always extends into the sliding slot 21, and the protrusion 314 is disposed offset from the rotation center of the rotating portion 32. This arrangement allows the rotating portion 32 to rotate the body portion 312 when the locking lever 20 is switched between the locked position and the unlocked position. Since the boss 314 is provided offset from the rotation center of the rotation portion 32, the boss 314 can rotate relative to the slide groove 21 when the main body 312 rotates, and the position of the lock lever 20 can be switched.

In addition, in the accommodating groove 313 of the middle body 312, the entire rotating portion 32 is not accommodated, but only the restricting structure 322 and the clutch inner 3212 of the rotating portion 32 are accommodated.

It should be noted that, in the present application, the driving motor 3211 is usually a reduction motor.

As shown in fig. 9 to 12, the slide groove 21 in the present application has a racetrack shape. By this arrangement, when the locking lever 20 is switched between the locking position and the unlocking position, the projection 314 of the locking head 31 is always located in the slide groove 21 and moves in one direction in the slide groove 21 relative to the locking lever 20, i.e. it always moves clockwise or counterclockwise along the racetrack-shaped slide groove 21.

Alternatively, the slide groove 21 includes a locking section, a connecting section, and an unlocking section, which are connected in sequence, located at both ends of the slide groove 21 in the axial direction of the locking rod 20, and respectively have a first holding position 215 and a second holding position 216; the connecting section extends along the axial direction of the locking rod 20, the locking section and the unlocking section are both arc-shaped, the connecting section is linear, and when the locking head 31 is positioned at the connecting section, the rotating part 32 idles. When the slide groove 21 is thus provided, the drive motor 3211 needs to have forward and reverse rotation functions.

It should be noted that, although the slide groove 21 is in the form of a race track in the present application, the slide groove 21 is not disposed around the locking rod 20 in the circumferential direction, but extends in the axial direction of the locking rod 20. That is, there are two points on the racetrack which are connected parallel to the length of the locking rod 20.

As shown in fig. 9 to 12, the slide groove 21 includes a locking groove section 211, a first connecting groove section 212, an unlocking groove section 213, and a second connecting groove section 214, which are connected in sequence, and the locking groove section 211 and the unlocking groove section 213 are located at both ends of the slide groove 21 in the axial direction of the locking rod 20, the first connecting groove section 212 and the second connecting groove section 214 extend in the axial direction of the locking rod 20, and a portion of a groove wall of the locking groove section 211 is recessed toward a direction away from the unlocking groove section 213 to form a first holding position 215, a portion of a groove wall of the unlocking groove section 213 is recessed toward a direction away from the locking groove section 211 to form a second holding position 216, and the rotating portion 32 idles when the locking head 31 is located at the first connecting groove section 212 and the second connecting groove section 214. With this arrangement, when the boss 314 of the locking head 31 is located at the first holding position 215, the locking rod 20 can be held at the locking position, and the locking rod 20 limits the locking head 31 by the first holding position 215, and the locking head 31 cannot rotate with the rotating portion 32. Also when the projection 314 of the locking head 31 is located at the second holding position 216, the locking rod 20 can be held at the unlocking position, and the locking rod 20 limits the locking head 31 by the second holding position 216, and the locking head 31 cannot rotate with the rotating portion 32.

Of course, the first holding position 215 can also be located in the middle of the locking groove section 211, and the second holding position 216 can also be located in the middle of the unlocking groove section 213, as long as the locking lever 20 can be held in the unlocking position or the locking position.

It should be noted that, although the projection 314 of the locking head 31 is capable of interacting with the locking lever 20 when the projection 314 is in the first 215 and second 216 retaining positions. However, when the position of the locking lever 20 needs to be switched, the locking lever 20 can move the locking head 31 out of the first holding position 215 or the second holding position 216 under the external force, but the locking head 31 is still located in the locking groove section 211 or the unlocking groove section 213, that is, the locking lever 20 is still in the locking position or the unlocking position. At this time, the driving motor 3211 can be started by unlocking or locking the electronic door lock using a matching key, so that the lock cylinder can be moved from the locking groove section 211 or the unlocking groove section 213 to the first connecting groove section 212 or the second connecting groove section 214.

It should be noted that the locking head 31 can only rotate with the rotating portion 32 when the locking groove section 211 or the unlocking groove section 213 switches to the first connecting groove section 212 or the second connecting groove section 214, and otherwise the rotating portion 32 idles.

In particular, the groove width of the locking groove section 211 and/or the unlocking groove section 213 at the first holding position 215 and/or the second holding position 216 is larger than the groove width of the sliding groove 21 at a position other than the first holding position 215 and the second holding position 216. By this arrangement, the protrusion 314 can interact with the locking rod 20 when located at the first holding position 215 or the second holding position 216 of the sliding groove 21, and the protrusion 314 and the locking rod 20 can be mutually limited.

Specifically, the chute 21 further includes a first stopping protrusion 217 and a second stopping protrusion 218, the inner ring side wall of the chute 21 in the shape of a racetrack ring has a first concave portion at the first holding position 215, and along the movement track of the locking head 31 in the chute 21, the first stopping protrusion 217 is disposed at the edge of the first holding position 215 on the side away from the movement direction of the locking head 31; the inner circumferential side wall of the raceway ring-shaped sliding groove 21 has a second recess at the second holding position 216, and a second stopper projection 218 is provided at an edge of the second holding position 216 on a side facing away from the movement direction of the locking head 31 along the movement trajectory of the locking head 31 in the sliding groove 21. By this arrangement, it can be ensured that the protrusion 314 can always move in the same direction during the movement relative to the slide groove 21, that is, when the protrusion 314 moves relative to the slide groove 21, the movement path is fixed to the cycle in which the locking groove section 211, the first connecting groove section 212, the unlocking groove section 213, and the second connecting groove section 214 finally return to the locking groove section 211, or the movement path is fixed to the cycle in which the locking groove section 211, the second connecting groove section 214, the unlocking groove section 213, and the first connecting groove section 212 finally return to the locking groove section 211. And by this arrangement, when the protruding portion 314 leaves the first holding position 215 or the second holding position 216 and enters the first connecting groove section 212 or the second connecting groove section 214 from the locking groove section 211 or the unlocking groove section 213, the protruding portion 314 enters the first concave portion or the second concave portion from the first holding position 215 or the second holding position 216, and then the protruding portion 314 is rotationally moved to the first connecting groove section 212 or the second connecting groove section 214 from the locking groove section 211 or the unlocking groove section 213 by the rotating portion 32.

Optionally, the outer ring side wall of the racetrack-shaped runner 21 has a third recess at the first 215 and/or second 216 retaining location.

As shown in fig. 4 and 6, the outer side wall of the locking lever 20 further has an emergency unlocking groove 22 communicating with the first holding position 215 or the second holding position 216 of the slide groove 21. Also, the protruding portion 314 can enter the emergency unlock groove 22 from the first holding position 215 or the second holding position 216 through the third recessed portion.

In one embodiment of the present application, the first retention bit 215 is located in the latch slot segment 211 and is connected to the emergency release slot 22.

And the emergency unlocking groove 22 communicates with the locking groove section 211, the locking lever 20 also has an emergency unlocking position.
