[0037] Such asFigures 1 to 11 As shown, the present application discloses an intelligent lock for being provided on a door body. As Figures 2 to 5 shown, the intelligent lock includes an outer lock case 1, a pan-tilt 2, a first driving mechanism 3 and a second driving mechanism 4. Among them, the outer lock case 1 is provided with an installation cavity 11 with an open front. The pan-tilt 2 is arranged in the installation cavity 11, and the pan-tilt 2 includes a mounting seat 21 connected to the outer lock case 1, a support frame 22 mounted on the mounting seat 21, and a pan-tilt main body 23 arranged on the support frame 22. Among them, as Figure 1 and Figure 2 shown, an identification module 24 is arranged on the pan-tilt main body 23.

[0038] As Figures 1 to 3 , Figure 6 and Figure 7 shown, the above-mentioned intelligent lock further includes a vertically arranged fixing seat 5. The fixing seat 5 is fixedly connected to the outer lock case 1, and the mounting seat 21 is fixedly connected to the fixing seat 5 and is vertically arranged. Specifically, in the outer lock case 1, a cavity 12 communicating with the installation cavity 11 is provided behind the installation cavity 11. At least part of the fixing seat 5 and part of the second driving mechanism 4 are located in the cavity 12.

[0039] As Figures 3 to 5 shown, the first driving mechanism 3 is arranged on the support frame 22, and a power output end of the first driving mechanism 3 is connected to the pan-tilt main body 23 to drive the pan-tilt main body 23 to rotate around a first axis A. The second driving mechanism 4 is arranged on the mounting seat 21, and a power output end of the second driving mechanism 4 is connected to the support frame 22 to drive the support frame 22 and the pan-tilt main body 23 to rotate relative to the mounting seat 21 around a second axis B. The second axis B extends along the up-down direction and intersects with the first axis A.

[0040] It can be understood that the identification module 24 is usually arranged on the pan-tilt main body 23. The second driving mechanism 4 drives the support frame 22 to rotate around the second axis B extending up and down. Since the pan-tilt main body 23 is arranged on the support frame 22, at this time, the second driving mechanism 4 will drive the pan-tilt main body 23 to rotate left and right through the support frame 22, so that when the user's face rotates left and right, it can be accurately identified by the identification module 24 on the pan-tilt main body, and the identified face information is more complete. And the first driving mechanism 3 can drive the pan-tilt main body 23 to rotate around the first axis A intersecting with the second axis B. At this time, the pan-tilt main body 23 can realize rotation in two directions, with a wide identification range and better meeting the needs of users.

[0041] The controller is electrically connected to the first driving mechanism 3 and the second driving mechanism 4. The specific principles of the controller for controlling the first driving mechanism 3 and the second driving mechanism 4 are the same. Taking the control of the second driving mechanism 4 as an example, a simple description is as follows: When the recognition module 24 recognizes that the user approaches the left or right side of the pan-tilt body 23, the recognition module 24 transmits the recognized position signal to the controller. Since the controller is electrically connected to the second driving mechanism 4, the controller controls the second driving mechanism 4 to act, so that the recognition module 24 of the pan-tilt body 23 is aligned with the user, so as to achieve the purpose of accurate recognition and / or unlocking. Since the specific control principle is the same as the principle of the controller controlling the driving mechanism in the prior art, it will not be described in detail in this embodiment.

[0042] The above-mentioned pan-tilt body 23 is a spherical head body, and the peripheral surface of the installation cavity 11 is a spherical surface. As Figure 3 shown, an accommodation cavity 230 with an open end facing backward is defined in the above-mentioned pan-tilt body 23, and the support frame 22 is located in the accommodation cavity 230. The above-mentioned pan-tilt body 23 is located at the center of the installation cavity 11, and the gap between the outer peripheral wall of the pan-tilt body 23 and the peripheral wall of the installation cavity 11 is uniform. In addition, a sealing ring 2312 is sleeved on the outer peripheral wall of the above-mentioned pan-tilt body 23 to form a sealed connection between the outer peripheral wall of the pan-tilt body 23 and the inner peripheral wall of the installation cavity 11. The existence of the sealing ring 2312 always maintains the sealed connection between the pan-tilt body 23 and the installation cavity 11 during the rotation of the pan-tilt body 23, preventing water, dust, etc. from entering the accommodation cavity of the pan-tilt body 23. In order to facilitate the installation of the sealing ring 2312, an annular groove 2311 for the sealing ring 2312 to be located therein is provided on the outer peripheral wall of the above-mentioned pan-tilt body 23.

[0043] In this embodiment, as Figure 4 and Figure 5 shown, the extending direction of the axis of the power output end of the first driving mechanism 3 is the same as the extending direction of the above-mentioned first axis A. The above-mentioned pan-tilt body 23 is connected to the support frame 22 through a connecting shaft 25. The first axis A is the axis of the connecting shaft 25, and the power output end of the first driving mechanism 3 is coaxially arranged with the connecting shaft 25. Thus, under the drive of the first driving mechanism 3, the pan-tilt body 23 rotates around the connecting shaft 25. In this embodiment, an assembly groove 220 is formed in the support frame 22, and the above-mentioned first driving mechanism 3 is a first motor located in the assembly groove 220.

[0044] In one embodiment, the connecting shaft 25 extends along the front-rear direction. When the user tilts the head to the left or right, the recognition module 24 of the pan-tilt body 23 can recognize the user. However, when tilting the head to the left or right, due to the limited angle, the information of the user, such as face recognition, is incomplete. Combining with the left-right rotation of the above-mentioned pan-tilt body 23, the user information can be recognized more comprehensively. In this embodiment, as Figure 2 、Figure 3 , Figure 4 and Figure 5 As shown in Figure 3 , Figure 4 and Figure 5 , the connecting shaft 25 extends along the left - right direction, and the second driving mechanism 4 is located behind the first driving mechanism 3. In this way, the pan - tilt body 23 swings back and forth by rotating around the connecting shaft 25, and can be recognized by the recognition module 24 on the pan - tilt body 23 when the human face looks up or down, and can also meet users of different heights, with a wide recognition range. In addition, since the second driving mechanism 4 is located behind the first driving mechanism 3, it avoids the second driving mechanism 4 interfering with the first driving mechanism 3, and the layout is more reasonable, which is convenient for realizing the rotation of the pan - tilt body 23 in two directions.

[0045] As Figure 5 shown in Figure 5 , a limiting structure 221 for rotating the pan - tilt body 23 between a first position and a second position is provided on the above - mentioned support frame 22, and the first position and the second position are located on the rotation path of the pan - tilt body 23 rotating around the connecting shaft 25. It can be understood that the existence of the limiting structure 221 can better limit the rotation stroke of the support frame 22 and improve the reliability of the rotation of the support frame 22.

[0046] In an embodiment, the limiting structure 221 includes two limiting plates arranged at intervals along the rotation direction of the support frame 22. A convex portion 251 is protruded on the outer peripheral wall of the connecting shaft 25. The convex portion 251 is located between the two limiting plates. In this embodiment, as Figure 5 and Figure 9 shown in Figure 5 and Figure 9 , the limiting structure 221 is a limiting groove for the convex portion 251 to be located therein. The limiting groove is opened on the support frame 22, and the limiting groove includes a first limiting plate 2211 and a second limiting plate 2212 arranged at intervals along the rotation direction of the connecting shaft 25. The first limiting plate 2211 is located below the second limiting plate 2212. In the state where the pan - tilt body 23 is in the first position, the convex portion 251 abuts against the first limiting plate 2211, and in the state where the pan - tilt body 23 is in the second position, the convex portion 251 abuts against the second limiting plate 2212. In this way, the first limiting plate 2211 limits the first position of the pan - tilt body 23 to prevent the convex portion 251 from further moving towards the first limiting plate 2211; while the second limiting plate 2212 limits the second position of the pan - tilt body 23 to prevent the convex portion 251 from further moving towards the second limiting plate 2212.

[0047] As Figure 4 and Figure 5As shown, the above intelligent lock further includes a first detector 2221 for detecting the states of the pan-tilt body 23 in the first position and the second position. The signal output terminal of the first detector 2221 is electrically connected to the controller, and the signal output terminal of the controller is electrically connected to the first motor. The controller is configured to: when the first detector 2221 detects a signal that the pan-tilt body 23 is in the first position or the second position, stop the first motor from working.

[0048] It can be understood that the presence of the first detector 2221 can detect the position of the pan-tilt body 23. When the detector detects that the pan-tilt body 23 is in the first position and the second position, a signal is transmitted to the controller, and the controller controls the first motor to stop working. At this time, the pan-tilt body 23 stops rotating.

[0049] As Figure 4 、 Figure 5 and Figure 9 shown, the above connecting shaft 25 is provided with a first support leg 252 and a second support leg 253. When the pan-tilt body 23 is in the first position state, the first support leg 252 moves with the connecting shaft 25 to a position corresponding to the first detector 2221. When the pan-tilt body 23 is in the second position state, the second support leg 253 moves with the connecting shaft 25 to a position corresponding to the first detector 2221. The presence of the first support leg 252 and the second support leg 253 facilitates the detector to detect the position of the pan-tilt body 23 and accurately transmit a signal to the controller.

[0050] In this embodiment, the first support leg 252 is located above the second support leg 253. The above support frame 22 is provided with a first detection plate 222, and the first detector 2221 is a detection switch provided on the first detection plate 222.

[0051] As Figures 1 to 3 shown, the above pan-tilt body 23 includes a spherical shell 231 with openings on both the front and rear sides and a cover plate 232 covering the front opening of the spherical shell 231. The cover plate 232 is connected to the spherical shell 231 by snap connection or screw connection. The identification module 24 is provided on the cover plate 232. The aforementioned identification module 24 is at least one of a cat's eye 241, a screen 242, and a face recognition module. In this embodiment, the identification module 24 includes a cat's eye 241 and a screen 242. In addition, a human body sensor or other functional components may be integrated on the pan-tilt body 23. The above sealing ring 2312 is located on the spherical shell 231.

[0052] As Figure 3 、 Figure 6 、 Figure 8 and Figure 9As shown in the figure, the second drive mechanism 4 includes a second motor 41 and a driving gear 42. The driving gear 42 is mounted on the output shaft of the second motor 41. The support frame 22 is mounted on the mounting base 21 through a mounting shaft 224 and is relatively fixed to the support frame 22. The second axis B is parallel to the axis of the mounting shaft 224 and is arranged at an interval. The support frame 22 is provided with a toothed transmission member beside the mounting shaft 224. The driving gear 42 meshes with the toothed transmission member to drive the support frame 22 to move back and forth between a third position and a fourth position. The third position and the fourth position are located on the rotation path of the support frame 22 rotating around the second axis.

[0053] It can be understood that the second motor 41 drives the driving gear 42 to rotate. Since the toothed transmission member meshes with the driving gear 42, the driving gear 42 drives the support frame 22 to rotate around the second axis B through the toothed transmission member. Since the pan-tilt body 23 is arranged on the support frame 22, at this time, the pan-tilt body 23 rotates together with the support frame 22.

[0054] As shown in Figure 6 , Figure 8 , Figure 9 and Figure 11 the figure, the toothed transmission member is an arc-shaped rack 223 arched towards the driving gear 42. An arc-shaped groove 211 arched towards the driving gear 42 is formed on the mounting base 21. The mounting shaft 224 is relatively fixed to the support frame 22, and the mounting shaft 224 is arranged in the arc-shaped groove 211. The mounting shaft 224 on the support frame 22 moves along the arc-shaped groove 211, that is to say, the support frame 22 moves along the arc-shaped groove 211. In this way, the left and right swing of the support frame 22 is realized.

[0055] The mounting shaft 224 is a screw fixedly connected to the support frame 22. As shown in Figure 6 the figure, the mounting shaft 224 extends along the up and down direction. There are two groups of the mounting shaft 224 and the arc-shaped groove 211, and they are arranged at an interval along the up and down direction. In this way, the cooperation of the two groups of the mounting shaft 224 and the arc-shaped groove 211 can reliably realize the left and right yaw of the support frame 22 and the pan-tilt body 23.

[0056] In this embodiment, as shown in Figure 6 and Figure 11 the figure, an assembly cavity 210 for accommodating the support frame 22 is formed in the mounting base 21. The top plate and the bottom plate of the assembly cavity 210 are both provided with the arc-shaped grooves 211. The two arc-shaped grooves 211 can be arranged oppositely or staggeredly. In this embodiment, the two arc-shaped grooves 211 are staggeredly arranged.

[0057] As shown in Figures 8 to 10As shown in the figure, the above-mentioned intelligent lock further includes a second detector 61 for detecting that the support frame 22 is in the third position and a third detector 62 for detecting that the support frame 22 is in the fourth position. Both the second detector 61 and the third detector 62 are electrically connected to the controller, and the signal output end of the controller is electrically connected to the second motor 41. The controller is configured to stop the second motor 41 when the second detector 61 detects that the support frame 22 is in the third position or when the third detector 62 detects that the support frame 22 is in the fourth position.

[0058] In addition, the above-mentioned intelligent lock further includes a fourth detector 63 for detecting that the support frame 22 is in the initial position. The above-mentioned second detector 61, third detector 62, and fourth detector 63 are all located on the circumferential side of the mounting shaft 224. In this embodiment, the second detector 61 is located on the left side of the third detector 62, and the fourth detector 63 is located behind the second detector 61.

[0059] As Figures 8 to 10 shown in the figure, the bottom of the above-mentioned support frame 22 is provided with a first bump 225 and a second bump 226, and the first bump 225 is located on the left side of the second bump 226. The above-mentioned mounting shaft 224 is located between the first bump 225 and the second bump 226. The second detector 61 and the fourth detector 63 are located on the movement path of the first bump 225, and the third detector 62 is located on the movement path of the second bump 226. When the first bump 225 corresponds to the fourth detector 63, the pan-tilt body 23 is in the initial position at this time. When the first bump 225 moves to a position corresponding to the second detector 61, the pan-tilt body 23 rotates to the left in place, and the second bump 226 is in front of the third detector 62. When the second bump 226 moves to a position corresponding to the third detector 62, the pan-tilt body 23 rotates to the right in place.

[0060] In this embodiment, as Figure 3 、 Figures 8 to 10 shown in the figure, a second detection board 6 relatively fixed to the mounting base 21 is installed below the above-mentioned mounting base 21, and the second detector 61, third detector 62, and fourth detector 63 are detection switches provided on the upper surface of the second detection board 6.

[0061] In addition, a transfer board is provided on the above-mentioned mounting base 21, and the transfer board is used to connect the lines inside the pan-tilt body 23 to the outside.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0063] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application.
