Description

Technical Field

[0001] The present invention relates to the technical field of smart locks, and in particular to smart locks. Background Art

[0002] At present, some smart locks have a face recognition unlocking function, which is usually realized by a function module such as a cat-eye monitoring module installed on the outer lock of the smart lock. However, since smart locks are usually installed at a lower position, when a user stands outside the door and tilts his head to the left or right to approach the smart lock to unlock it, face recognition is usually not possible due to incomplete or incorrect facial information, which leads to failure of face recognition unlocking of the smart lock. Summary of the invention

[0003] In view of this, the present invention provides a smart lock to solve the problem that face recognition cannot be performed when the user tilts his head to the left or to the right to unlock the lock.

[0004] The present invention provides a smart lock, comprising:

[0005] An outer lock housing, wherein a mounting hole is provided on the outer lock housing;

[0006] A pan head body, rotatably connected to the mounting hole;

[0007] A face recognition module is connected to the gimbal body;

[0008] A first driving mechanism, disposed in the outer lock housing, for driving the pan / tilt head body to rotate around the R axis;

[0009] A controller is communicatively connected to the face recognition module and the first driving mechanism.

[0010] Beneficial effects: The outer lock shell is usually installed outside the door, and the face recognition module is connected to the pan-tilt body and can move under the drive of the pan-tilt body; through the setting of the first driving mechanism, the pan-tilt body can be driven to rotate around the R axis, so that users who tilt their heads to the left or right can perform face recognition and unlock relatively smoothly. When the face recognition module recognizes that the user is ready to unlock, it first recognizes the user's posture. If the user tilts his head to the left or right to approach the face recognition module of the smart lock, the face recognition module will feedback the user's head tilt information to the controller. The controller controls the action of the first driving mechanism according to the user's head tilt information. The first driving mechanism drives the pan-tilt body to rotate around the R axis, driving the face recognition module to rotate around the R axis. After rotating to a position that matches the user's head tilt to the left or right, the face recognition module can normally recognize the face and unlock, expanding the range of recognition and unlocking by the face recognition module.

[0011] In an optional embodiment, it also includes a transmission shaft, which is rotatably connected to the outer lock shell around the R axis; the first driving mechanism is fixedly connected to the outer lock shell, and the first output shaft of the first driving mechanism is fixedly connected to the transmission shaft, and is fixedly connected to the gimbal body through the transmission shaft.

[0012] Beneficial effect: The transmission shaft can transmit the action of the first driving mechanism to the pan / tilt body, thereby driving the pan / tilt body.

[0013] In an optional embodiment, a second driving mechanism is further included, which is communicatively connected to the controller, and the second driving mechanism is arranged in the outer lock shell, and is used to drive the gimbal body to rotate around the Y axis, and the Y axis is perpendicular to the R axis.

[0014] Beneficial effect: The second drive mechanism can drive the pan-tilt body to rotate around the Y axis, so that both tall and short users can perform face recognition and unlock more smoothly. When the face recognition module recognizes that the user is ready to unlock, it first identifies the position of the user's head. If the user's head is higher or lower than the face recognition module, the face recognition module will feedback the user's height information to the controller. The controller controls the second drive mechanism to operate according to the user's height information. The second drive mechanism drives the pan-tilt body to rotate around the Y axis, driving the face recognition module to rotate around the Y axis. After rotating to a position that matches the height of the user's head, the face recognition module can normally recognize the face and unlock, expanding the range of recognition and unlocking by the face recognition module.

[0015] In an optional embodiment, the outer lock shell includes a front shell, a rear shell and a partition bar, the front shell is connected to the rear shell, the partition bar is fixedly connected to the rear shell and is spaced between the front shell and the rear shell, the mounting hole is arranged on the front shell, the first driving mechanism is fixedly connected to the rear shell and is located between the rear shell and the partition bar, and the transmission shaft is rotatably connected to the partition bar.

[0016] Beneficial effect: The partition bar can rotatably support the transmission shaft, thereby enhancing the stability of the transmission shaft.

[0017] In an optional embodiment, a connecting through hole is provided on the dividing bar, an annular groove is provided on the outer periphery of the transmission shaft, and the transmission shaft is rotatably connected to the connecting through hole through the annular groove.

[0018] Beneficial effect: The cooperation between the connecting through hole and the annular groove can not only realize the rotation support of the transmission shaft, but also limit the transmission shaft in the axial direction of the transmission shaft to prevent the transmission shaft from moving in the axial direction.

[0019] In an optional embodiment, one end of the transmission shaft is fixedly connected to the first output shaft, and the other end extends into the interior of the gimbal body and is connected to the gimbal body.

[0020] Beneficial effect: One end of the transmission shaft is fixedly connected to the first output shaft, and the other end extends to the interior of the gimbal body, which not only increases the distance between the first drive mechanism and the gimbal body to prevent the first drive mechanism from interfering with the rotation of the gimbal body, but also because the other end extends to the interior of the gimbal body, it can also avoid occupying the space outside the gimbal body.

[0021] In an optional embodiment, the gimbal body is spherical, with an opening provided at one end facing the rear shell, a avoidance groove connected to the opening is provided on the side wall of the gimbal body, and the dividing strip is arranged in the avoidance groove.

[0022] Beneficial effect: The setting of the avoidance groove can avoid the gimbal body during the rotation of the gimbal body around the R axis and the Y axis, thereby ensuring the smooth rotation of the gimbal body.

[0023] In an optional embodiment, the second driving mechanism is fixedly connected to the gimbal body, and the second output shaft of the second driving mechanism is fixedly connected to the transmission shaft.

[0024] Beneficial effect: The second drive mechanism is fixedly connected to the gimbal body, which can reasonably utilize the space inside the gimbal body and reduce the space occupied by the second drive mechanism in the outer lock shell; since the transmission shaft is rotatably connected around the R axis, and the R axis is perpendicular to the Y axis, when the second output shaft rotates, the transmission shaft does not move, causing the second drive mechanism to drive the gimbal body to rotate.

[0025] In an optional embodiment, a D-shaped transmission hole is provided on the transmission shaft, and the second output shaft is a D-shaped output shaft with a D-shaped cross-section, and the D-shaped output shaft is connected in the D-shaped transmission hole.

[0026] Beneficial effect: The D-type transmission hole cooperates with the D-type output shaft to prevent the D-type output shaft from rotating relative to the D-type transmission hole, so as to ensure that the second driving mechanism can drive the pan / tilt head body to rotate around the Y-axis.

[0027] In an optional embodiment, a display screen is further included, which is fixedly connected to the pan head body, located outside the outer lock shell, and is communicatively connected to the controller.

[0028] Beneficial effects: The display screen can interact with the user by displaying animations such as expressions, and displaying the rotation of the gimbal body around the Y axis and around the R axis. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0040] According to an embodiment of the present invention, a smart lock is provided, including an outer lock shell 1, a gimbal body 2, a face recognition module 3, a first drive mechanism 4 and a controller; a mounting hole is provided on the outer lock shell 1; the gimbal body 2 is rotatably connected to the mounting hole; the face recognition module 3 is connected to the gimbal body 2; the first drive mechanism 4 is arranged in the outer lock shell 1, and is used to drive the gimbal body 2 to rotate around the R axis; the controller is communicatively connected to the face recognition module 3 and the first drive mechanism 4.

[0041] The outer lock shell 1 is usually installed outside the door, and the face recognition module 3 is connected to the pan-tilt body 2 and can move under the drive of the pan-tilt body 2; through the setting of the first driving mechanism 4, the pan-tilt body 2 can be driven to rotate around the R axis, so that users who tilt their heads to the left or to the right can perform face recognition and unlock relatively smoothly. When the face recognition module 3 recognizes that the user is ready to unlock, it first recognizes the user's posture. If the user tilts his head to the left or to the right to approach the face recognition module 3 of the smart lock, the face recognition module 3 will feedback the user's head tilt information to the controller. The controller controls the first driving mechanism 4 to act according to the user's head tilt information. The first driving mechanism 4 drives the pan-tilt body 2 to rotate around the R axis, driving the face recognition module 3 to rotate around the R axis. After rotating to a position that matches the user's head tilt to the left or to the right, the face recognition module 3 can normally recognize the face and unlock, expanding the range of recognition and unlocking by the face recognition module 3.

[0042] Among them, the way in which the face recognition module 3 recognizes the user's posture may include automatic recognition through images, as well as information actively input by the user through the input panel of the smart lock.

[0043] Specifically, in this embodiment, the communication connection includes electrical connection through a wire, and wireless connection through WIFI, a cellular network, etc.

[0044] In one embodiment, it also includes a transmission shaft 5, which is rotatably connected to the outer lock shell 1 around the R axis; the first drive mechanism 4 is fixedly connected to the outer lock shell 1, and the first output shaft 41 of the first drive mechanism 4 is fixedly connected to the transmission shaft 5, and is fixedly connected to the pan head body 2 through the transmission shaft 5.

[0045] The transmission shaft 5 can transmit the action of the first driving mechanism 4 to the pan / tilt main body 2, thereby driving the pan / tilt main body 2. In addition, the transmission shaft 5 has a simple structure and does not occupy too much space in the outer lock housing 1.

[0046] In one embodiment, a second driving mechanism 6 is further included, which is communicatively connected to the controller. The second driving mechanism 6 is disposed in the outer lock shell 1 and is used to drive the pan head body 2 to rotate around the Y axis, and the Y axis is perpendicular to the R axis.

[0047] The second drive mechanism 6 is set to drive the pan-tilt body 2 to rotate around the Y axis, so that both tall and short users can perform face recognition and unlock relatively smoothly. When the face recognition module 3 recognizes that the user is ready to unlock, it first recognizes the position of the user's head. If the user's head is higher or lower than the face recognition module 3, the face recognition module 3 will feedback the user's height information to the controller. The controller controls the second drive mechanism 6 to operate according to the user's height information. The second drive mechanism 6 drives the pan-tilt body 2 to rotate around the Y axis, driving the face recognition module 3 to rotate around the Y axis. After rotating to a position that matches the height of the user's head, the face recognition module 3 can normally recognize the face and unlock, expanding the range of recognition and unlocking by the face recognition module 3.

[0048] Among them, the way in which the face recognition module 3 recognizes the user's height may include automatic recognition through images, as well as information actively input by the user through the input panel of the smart lock.

[0049] In one embodiment, the outer lock shell 1 includes a front shell 11, a rear shell 12 and a partition bar 13. The front shell 11 is connected to the rear shell 12, the partition bar 13 is fixedly connected to the rear shell 12 and is spaced between the front shell 11 and the rear shell 12. The mounting hole is set on the front shell 11, the first drive mechanism 4 is fixedly connected to the rear shell 12 and is located between the rear shell 12 and the partition bar 13, and the transmission shaft 5 is rotatably connected to the partition bar 13.

[0050] The partition bar 13 can rotatably support the transmission shaft 5, thereby enhancing the stability of the transmission shaft 5. The partition bar 13 occupies less space in the outer lock housing 1, and the partition bar 13 supports the rotation of the transmission shaft 5, and also increases the distance between the first driving mechanism 4 and the pan / tilt body, thereby preventing the first driving mechanism 4 from affecting the rotation range of the pan / tilt body.

[0051] In one embodiment, a connecting through hole is provided on the partition bar 13 , and an annular groove 51 is provided on the outer periphery of the transmission shaft 5 . The transmission shaft 5 is rotatably connected to the connecting through hole via the annular groove 51 .

[0052] The cooperation between the connecting through hole and the annular groove 51 can not only realize the rotation support of the transmission shaft 5, but also limit the transmission shaft 5 in the axial direction of the transmission shaft 5 to prevent the transmission shaft 5 from moving in the axial direction.

[0053] Specifically, the first driving mechanism 4 is a motor, and the first output shaft 41 is a rotation output shaft of the motor.

[0054] In one embodiment, one end of the transmission shaft 5 is fixedly connected to the first output shaft 41 , and the other end is extended into the interior of the gimbal body 2 and connected to the gimbal body 2 .

[0055] One end of the transmission shaft 5 is fixedly connected to the first output shaft 41, and the other end extends to the interior of the gimbal body 2, which not only increases the distance between the first drive mechanism 4 and the gimbal body 2 to prevent the first drive mechanism 4 from interfering with the rotation of the gimbal body 2, but also because the other end extends to the interior of the gimbal body 2, it can also avoid occupying the space outside the gimbal body 2.

[0056] In one embodiment, the gimbal body 2 is spherical, and an opening is provided at one end facing the rear shell 12 . An avoidance groove 21 communicating with the opening is provided on the side wall of the gimbal body 2 , and the dividing strip 13 is disposed in the avoidance groove 21 .

[0057] The setting of the avoidance groove 21 can avoid the pan-tilt head body 2 during the process of the pan-tilt head body 2 rotating around the R axis and the Y axis, thereby ensuring the smooth rotation of the pan-tilt head body 2.

[0058] In a specific embodiment, the extension direction of the avoidance groove 21 is perpendicular to the Y axis, and the rotation angle of the pan / tilt body 2 around the Y axis can be limited. The width of the avoidance groove 21 is greater than the width of the partition bar 13 .

[0059] Furthermore, a face peephole window 7 is provided on the pan-tilt body 2, and the face recognition module 3 is arranged inside the pan-tilt body 2 and located at the face peephole window 7. The effective detection range of the face recognition module 3 is 150°, and the detection range of the face peephole window 7 is 160°. The pan-tilt body 2 rotates around the Y axis under the drive of the second driving mechanism 6. When both the upper and lower sides can rotate 30°, the face recognition module 3 and the face peephole window 7 can both reach a 180° field of view coverage in the upper and lower directions, which can meet the needs of users with taller heights for face recognition, and can also meet the needs of users such as children with a height of 50 to 120 cm for face recognition. In a preferred embodiment, there are two avoidance grooves 21 arranged relatively to each other, and the rotation angle of the pan-tilt body 2 on the Y axis can be limited to 30° above and below by the two avoidance grooves 21.

[0060] In one embodiment, the second driving mechanism 6 is fixedly connected to the pan / tilt head body 2 , and the second output shaft 61 of the second driving mechanism 6 is fixedly connected to the transmission shaft 5 .

[0061] The second driving mechanism 6 is fixedly connected to the pan-tilt head body 2, which can reasonably utilize the space inside the pan-tilt head body 2 and reduce the space occupied by the second driving mechanism 6 in the outer lock shell 1; since the transmission shaft 5 is rotatably connected around the R axis, and the R axis is perpendicular to the Y axis, therefore, when the second output shaft 61 rotates, since the transmission shaft 5 is stationary, the second driving mechanism 6 drives the pan-tilt head body 2 to rotate.

[0062] In one embodiment, a D-shaped transmission hole is provided on the transmission shaft 5, and the second output shaft 61 is a D-shaped output shaft with a D-shaped cross section, and the D-shaped output shaft is connected in the D-shaped transmission hole.

[0063] The D-type transmission hole cooperates with the D-type output shaft to prevent the D-type output shaft from rotating relative to the D-type transmission hole, so as to ensure that the second driving mechanism 6 can drive the pan / tilt head body 2 to rotate around the Y-axis.

[0064] As a convertible implementation, the transmission hole on the transmission shaft 5 may be a polygonal hole, and the second output shaft 61 may be a polygonal column of matching shape.

[0065] In one embodiment, a display screen is also included, which is fixedly connected to the pan head body 2 and is located outside the outer lock shell 1 and is communicatively connected to the controller.

[0066] The display screen can interact with the user by displaying animations such as expressions, and displaying the rotation of the pan / tilt body 2 around the Y axis and around the R axis.

[0067] In this embodiment, the smart lock can also have conventional unlocking methods such as touch input password, fingerprint, etc.

[0068] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
