Meanwhile, a receiving hole 33 is further formed in the side wall of the mounting sleeve 31, and the receiving hole 33 is mainly used for receiving or temporarily storing the ball 43 in the unlocking assembly 4. In general, the receiving holes 33 may be opened in a radial direction of the mounting sleeve 31, and may be symmetrically opened in two. Of course, the receiving holes 33 may be opened more along the circumferential direction of the mounting sleeve 31, and the specific number thereof is generally equivalent to the number of the balls 43.

As shown in fig. 6 and 7, fig. 6 is a specific structural schematic diagram of the unlocking assembly 4, and fig. 7 is another view schematic diagram of fig. 6.

In an alternative embodiment with respect to the unlocking assembly 4, the unlocking assembly 4 essentially comprises an adapter cap 41, a cam 42 and a ball 43.

The adapter cover 41 covers an end surface of the mounting sleeve 31 (an end surface close to an output shaft of the driving motor 32), and can perform a rotation movement relative to the mounting sleeve 31, which is equivalent to being rotatably sleeved outside the mounting sleeve 31.

The cam 42 is arranged in the mounting sleeve 31 and is specifically positioned at the end part position in the mounting sleeve 31, which is close to the output shaft of the driving motor 32, and the rotating shaft of the cam 42 is in power connection with the output shaft of the driving motor 32 and can rotate synchronously with the output shaft of the driving motor 32. The radius of the cam 42 is different in size, the maximum value is equivalent to the inner diameter of the mounting sleeve 31, namely the circumferential surface of the cam 42 can be abutted against the inner wall of the mounting sleeve 31; the minimum value is smaller than the inner diameter of the mounting sleeve 31, i.e. the circumferential surface of the cam 42 leaves a clearance with the inner wall of the mounting sleeve 31.

The balls 43 are temporarily stored in the receiving holes 33 in the side wall of the mounting sleeve 31, and the inner spherical surface thereof is mainly used for being in fit abutment with the circumferential surface of the cam 42: when the cam 42 rotates, the ball 43 is pushed out by the circumferential surface of the cam 42 with the radius increasing, so that the ball 43 rolls out of the receiving hole 33 (the part of the ball 43 may be outside the receiving hole 33).

Meanwhile, a plurality of abutting grooves 411, for example, 2 to 8 abutting grooves 411 are formed in the inner end surface of the adapter cover 41 in the circumferential direction, the abutting grooves 411 are mainly used for being matched with the outer spherical surface of the ball 43, so that the ball 43 is abutted and pressed against the outer spherical surface of the ball 43 after being ejected out of the accommodating hole 33 by the cam 42, and a certain friction force is formed by utilizing a positive pressure between contact surfaces, thereby realizing temporary combination of the cam 42, the ball 43 and the adapter cover 41, and in this state, the power of the driving motor 32 can be transmitted to the adapter cover 41 through the cam 42, and further driving the adapter cover 41 to rotate.

As a whole, the cam 42, the ball 43 and the adapter cover 41 form a clutch structure, and the friction contact between the ball 43 and the contact groove 411 is used to realize the combination and power transmission between the cam 42 and the adapter cover 41; when the circumferential surface of the cam 42 with a gradually decreasing radius is in fit abutment with the inner spherical surface of the ball 43, the positive pressure between the outer spherical surface of the ball 43 and the abutment groove 411 is reduced until it disappears, so that the frictional abutment between the ball 43 and the abutment groove 411 is reduced until it disappears, and the cam 42 and the adaptor cover 41 are disengaged.

Generally, two balls 43 are disposed at the same time, and are symmetrically distributed in the mounting sleeve 31, and are respectively mounted in the receiving holes 33 distributed at both radial ends of the mounting sleeve 31, so that when the cam 42 is combined with the adapting cover 41, two power transmission positions exist at the same time, and the motion transmission is more stable and balanced. Of course, only one or more balls 43 may be provided.

Meanwhile, in order to prevent the balls 43 from accidentally rolling out of the receiving holes 33, the cam 42 is further provided with an arc-shaped groove 421 on the circumferential surface thereof, so that the balls 43 are received by the arc-shaped groove 421. Of course, the opening position of the arc-shaped slot 421 needs to avoid the action surface portion with the increasing radius for ejecting the ball 43.

In addition, in order to facilitate the adaptor cover 41 to drive the latch bolt 5 to perform the unlocking motion, the present embodiment is provided with a driving plate 412 on the outer end surface of the adaptor cover 41, so that when the adaptor cover 41 rotates, the driving plate 412 rotates synchronously, thereby converting the rotating motion into the unlocking motion of the latch bolt 5.

As shown in fig. 8, fig. 8 is a bottom view of fig. 6.

In an alternative embodiment of the latch bolt 5, two latch bolts 5 are provided at the same time and are respectively inserted telescopically at two radial end positions of the lower casing 12. Meanwhile, the two lock tongues 5 are not arranged in a collinear way, but are arranged in parallel. The driving plate 412 of the adapter cover 41 is generally in the shape of a long straight plate, and the inner end surfaces of the two locking tongues 5 abut against the two side surfaces of the driving plate 412. With such an arrangement, when the adapter cover 41 rotates, the driving plate 412 rotates synchronously, and abuts against the end surfaces of the inner ends of the two lock tongues 5, so that the two lock tongues 5 synchronously move in opposite directions along the radial direction, that is, one lock tongue 5 moves towards one end in the radial direction, and the other lock tongue 5 moves towards the other end in the radial direction, thereby achieving the effect that the outer ends of the two lock tongues 5 both retract inwards, and realizing unlocking; otherwise, locking is carried out.

In an optional embodiment of the reset component 6, the reset component 6 is specifically a spring, and there are two, the two springs are both disposed between the inner end of one of the lock tongues 5 and the outer end of the other lock tongue 5, that is, one end of the first spring abuts (or is connected to) the end surface of the inner end of the first lock tongue 5, and the other end of the first spring abuts the outer end of the second lock tongue 5; one end of the second spring is abutted (or connected) to the inner end face of the second lock tongue 5, and the other end of the second spring is abutted to the outer end of the first lock tongue 5. With the arrangement, when the power connection between the cam 42 and the switching cover 41 is disconnected, the two lock tongues 5 synchronously move in opposite directions under the action of the elastic force of the reset component 6, so that the outer ends of the two lock tongues 5 respectively extend out of the lower shell 12, and the locking state is automatically recovered.

The embodiment also provides an intelligent lock, which mainly comprises an automatic switch lock cylinder, wherein the specific content of the automatic switch lock cylinder is the same as the related content, and the details are not repeated here.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
