Compact intelligent lock

Abstract

According to the technical scheme, the compact intelligent lock is characterized by comprising a lock cylinder, a handle, a plug pin assembly, a control shaft, a control assembly, a camera shooting assembly, an electric control assembly, a magnetic attraction assembly, a mechanical assembly, a blocking assembly, a covering assembly and a moving assembly. No matter whether the electric control assembly is started to drive the control shaft to rotate or the mechanical assembly is used for manually controlling the control shaft to rotate, opening and closing of the lock are achieved through the same connecting core, and therefore the lock substantially uses two different power sources to control the same lock cylinder system. Compared with an intelligent lock which only can realize automatic control and manual control functions by using two sets of lock cylinder systems in the prior art, the intelligent lock has the advantages that the actual volume of the lock is compressed, and the lock can be applied to places with narrow mounting spaces.

Description

Technical Field

[0001] The present invention relates to a smart lock, and more particularly, to a compact smart lock. Background Art

[0002] A smart lock is an improved lock based on a traditional mechanical lock. It is more intelligent and simple in terms of user security, identification, and manageability. Smart locks in the prior art include components such as a motor for controlling the movement of a plug rod. In addition, some smart locks also have an additional mechanical system for controlling the movement of the plug rod to ensure that the lock can be opened manually when there is no power. However, such a composite lock actually uses two relatively independent lock core control systems, which makes the lock bulky and cannot be installed in a narrow place where controls are installed. Therefore, a compact smart lock is needed, the mechanical system of which can be controlled both automatically and manually, so that the entire mechanical lock shell is smaller.

[0003] In view of the above reasons, how to design a mechanical system that can be controlled both automatically and manually is exactly the problem considered in this application. Summary of the invention

[0004] In view of the deficiencies in the prior art, a compact intelligent lock is provided, the mechanical system of which can be controlled both automatically and manually.

[0005] To achieve the above-mentioned purpose, the following technical scheme is provided: a compact intelligent lock, comprising a lock cylinder, a handle, a latch assembly, a control shaft, a control assembly, a camera assembly, an electric control assembly, a magnetic suction assembly, a mechanical assembly, an obstruction assembly, a covering assembly and a moving assembly, wherein the obstruction assembly, the control shaft, the control assembly, the electric control assembly and the mechanical assembly are all installed in the handle, the camera assembly, the covering assembly and the moving assembly are all installed on the surface of the handle, the obstruction assembly is used to block the key from being inserted into the correct position of the mechanical assembly, the covering assembly is used to block the key from being inserted into the mechanical assembly, the lock cylinder is fixedly connected to the handle, the latch assembly is installed in the lock cylinder, the control shaft is connected to the latch assembly and is used to control the latch assembly, the electric control assembly and the mechanical assembly are all connected to the control shaft and are all used to drive the control shaft to rotate, the control assembly, the camera assembly, the electric control assembly and the moving assembly form a first circuit, the camera assembly is used to scan up and down and recognize a face, the control assembly, the magnetic suction assembly and the moving assembly form a second circuit, the first circuit and the second circuit are connected in parallel, and the moving assembly is used to drive the covering assembly to move and control the first circuit;

[0006] When the control moving component is connected to the first circuit, the camera component is started, the electric control component is started, and the control shaft is driven to rotate;

[0007] When the control component is powered, the second circuit is connected, the magnetic component restricts the movement of the cover component, the cover component restricts the key from being inserted into the mechanical component, and the obstruction component restricts the key from being inserted into the correct position in the mechanical component;

[0008] When the control component is out of power and the moving component is controlled to move, the second circuit is disconnected, the magnetic attraction component is closed, the covering component moves, and the key is inserted into the correct position in the mechanical component.

[0009] In summary, the above technical solution has the following beneficial effects: the compact smart lock needs to simplify a large number of useless functions, so the core function is mainly electronic lock, various additional intelligent recognition components can be installed in the form of additional installation, and are electrically connected to the control component for signal transmission, the camera component has a basic intelligent recognition function, can recognize the face, and in order to prevent the face from not being recognized due to height and other reasons, the camera component needs to be able to scan up and down, and can only send a signal when the camera component recognizes the correct face, so that the electronic control component can continue to operate;

[0010] From the appearance point of view, the main body of the present invention is a handle, and the moving component is installed at the position where the index finger is when the handle is normally held, so that the user can realize the unlocking function while pulling the door, and when installing, only the installation position of the handle needs to be considered, and the lock core is directly installed in the door, and opening from the outside of the door can reduce the space required for installation;

[0011] When in use, the moving component needs to be controlled. If the moving component is connected to the first circuit, the electric control component will start, thereby driving the control shaft to rotate forward or reverse, and the control shaft controls the latch component to realize the unlocking or locking function;

[0012] In actual use, the lock may be forcibly opened with a key or by a thief using a lock-opening tool. Therefore, when the control component is powered, the second circuit is connected, and the magnetic component restricts the movement of the cover component, so that the lock hole of the mechanical component is not exposed, and the cover component restricts the key from being inserted into the mechanical component, and the obstruction component restricts the key from being inserted into the correct position of the mechanical component.

[0013] If you want to use the key normally to realize the mechanical unlocking function, you need to use it when the control component is out of power. Because the second circuit is out of power and disconnected, the magnetic component is closed, so that the moving component can drive the control moving component to move, the covering component will also move and expose the lock hole, and the obstruction component will no longer prevent the key from being inserted into the correct position of the mechanical component, thereby avoiding the failure of the smart lock due to power failure;

[0014] The control shaft can be directly inserted into the latch assembly of the lock core to form a latch lock structure, or it can be connected to a lock tongue structure through other components, and the translation of the lock tongue can be achieved by rotation. Since the latch lock structure and the lock tongue structure are both existing technologies, they will not be described in detail.

[0015] In the present invention, no matter starting the electric control component to drive the control shaft to rotate or manually controlling the control shaft to rotate through the mechanical component, the switch of the lock is realized through the same connection core. Therefore, the lock of the present invention essentially uses two different power sources to control the same set of lock core systems. Compared with the prior art that uses two sets of lock core systems to realize the smart lock with both automatic control and manual control functions, the actual volume of the lock is compressed, so that the lock can be used in places with narrow installation space.

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0032] Reference Figure 1-5 As shown, the compact smart lock includes a lock core 1, a handle 2, a latch assembly 11, a control shaft 21, a control assembly 3, a camera assembly 41, an electric control assembly 4, a magnetic suction assembly 5, a mechanical assembly 6, an obstruction assembly 7, a cover assembly 8 and a moving assembly 9. The obstruction assembly 7, the control shaft 21, the control assembly 3, the electric control assembly 4 and the mechanical assembly 6 are all installed in the handle 2, the camera assembly 41, the cover assembly 8 and the moving assembly 9 are all installed on the surface of the handle 2, the obstruction assembly 7 is used to block the key from being inserted into the correct position of the mechanical assembly 6, the cover assembly 8 is used to block the key from being inserted into the mechanical assembly 6, and the lock core 1 is fixedly connected to the handle 2, the latch assembly 11 is installed in the lock core 1, the control shaft 21 is connected to the latch assembly 11 and is used to control the latch assembly 11, the electric control assembly 4 and the mechanical assembly 6 are both connected to the control shaft 21 and are both used to drive the control shaft 21 to rotate, the control assembly 3, the camera assembly 41, the electric control assembly 4 and the moving assembly 9 form a first circuit, the camera assembly 41 is used to scan up and down and recognize the face, the control assembly 3, the magnetic attraction assembly 5 and the moving assembly 9 form a second circuit, the first circuit and the second circuit are connected in parallel, and the moving assembly 9 is used to drive the covering assembly 8 to move and control the first circuit;

[0033] When the control moving assembly 9 is connected to the first circuit, the camera assembly 41 is started, the electric control assembly 4 is started, and the control shaft 21 is driven to rotate;

[0034] When the control component 3 is powered, the second circuit is connected, the magnetic component 5 restricts the cover component 8 from moving, the cover component 8 restricts the key from being inserted into the mechanical component 6, and the obstruction component 7 restricts the key from being inserted into the correct position in the mechanical component 6;

[0035] When the control component 3 is out of power and the moving component 9 is controlled to move, the second circuit is disconnected, the magnetic attraction component 5 is closed, the covering component 8 moves, and the key is inserted into the correct position in the mechanical component 6.

[0036] The compact smart lock needs to simplify a large number of useless functions, so the core function is mainly electronic lock. Various additional intelligent recognition components can be installed in the form of additions and electrically connected to the control component 3 for signal transmission. The camera component 41 has a basic intelligent recognition function and can recognize faces. In order to prevent the face from not being recognized due to height and other reasons, the camera component 41 needs to be able to scan up and down, and can only send a signal when the camera component 41 recognizes the correct face, so that the electronic control component 4 can continue to operate;

[0037] From the appearance point of view, the main body of the present invention is the handle 2, and the moving component 9 is installed at the position where the index finger is when the handle 2 is normally held, so that the user can realize the unlocking function while pulling the door, and when installing, only the installation position of the handle 2 needs to be considered, and the lock core 1 is directly installed in the door, and opening from the outside of the door can reduce the space required for installation;

[0038] When in use, the moving assembly 9 needs to be controlled. If the moving assembly 9 is controlled to be connected to the first circuit, the electric control assembly 4 will be started, thereby driving the control shaft 21 to rotate forward or reversely, and the control shaft 21 controls the latch assembly 11 to realize the unlocking or locking function;

[0039] In actual use, the lock may be forcibly opened with a key or by a thief using a lock-opening tool. Therefore, when the control component 3 is powered, the second circuit is connected, and the magnetic component 5 restricts the movement of the cover component 8, so that the lock hole 631 of the mechanical component 6 is not exposed, and the cover component 8 restricts the key from being inserted into the mechanical component 6, and the blocking component 7 restricts the key from being inserted into the correct position in the mechanical component 6;

[0040] If you want to use the key normally to realize the mechanical unlocking function, you need to use it when the control component 3 is out of power. Because the second circuit is out of power and disconnected, the magnetic component 5 is closed, so that the moving component 9 can drive the moving component 9 to move, the covering component 8 will also move and expose the lock hole 631, and the blocking component 7 will no longer prevent the key from being inserted into the correct position of the mechanical component 6, thereby preventing the smart lock from failing due to power failure;

[0041] The control shaft 21 can be directly inserted into the latch assembly 11 of the lock core 1 to form a latch lock structure, or can be connected to a lock tongue structure through other components, and the translation of the lock tongue can be achieved by rotation. Since the latch lock structure and the lock tongue structure are both existing technologies, they will not be described in detail.

[0042] In the present invention, no matter starting the electric control component 4 to drive the control shaft 21 to rotate or manually controlling the control shaft 21 to rotate through the mechanical component 6, the switch of the lock is realized through the same connection core. Therefore, the lock of the present invention essentially uses two different power sources to control the same set of lock core 1 systems. Compared with the prior art that uses two sets of lock core 1 systems to realize the smart lock with both automatic control and manual control functions, the actual volume of the lock is compressed, so that the lock can be used in places with narrow installation space.

[0043] Further, a first receiving groove 22 is provided in the handle 2, the moving assembly 9 includes a moving member 91, a first moving resisting member 92, a first electrical connection resisting member 93 and a first spring 94, the electric control assembly 4 includes a first switch 42 and a second switch 43, the moving member 91 abuts against the first moving resisting member 92, the first moving resisting member 92 is fixedly connected to the first electrical connection resisting member 93, the first electrical connection resisting member 93 is slidably connected in the first receiving groove 22, the first switch 42 and the second switch 43 are respectively provided on both sides of the first electrical connection resisting member 93, and the two ends of the first spring 94 are respectively fixedly connected to the inner wall of the first receiving groove 22 and the first moving resisting member 92;

[0044] When the first electrical connection abutment 93 abuts against the first switch 42, the first circuit is connected, and the control shaft 21 rotates in the positive direction;

[0045] When the first electrical connection abutment member 93 abuts against the second switch 43 , the first circuit is connected, and the control shaft 21 rotates in the reverse direction.

[0046] The moving member 91 is a component for realizing the mechanical switch in the entire moving assembly 9. The moving member 91 itself has no control function. The moving member 91 drives the first electrical connection resistance member 93 to move by contacting the first moving resistance member 92, and drives the second electrical connection resistance member 96 to move by contacting the second moving resistance member 95.

[0047] Normally, the first electrical connection abutment 93 is always in contact with the second switch 43, so that the control component 3 can be given a signal to keep the control shaft 21 rotating in the opposite direction through the mechanical structure, thereby preventing the electric control component 4 from being accidentally started and directly unlocked, and the first circuit can be always connected, so that the electric control component 4 can be directly controlled by the control component 3 through the app control or other methods;

[0048] When the first electrical connection abutment 93 abuts against the first switch 42, a signal that the control shaft 21 rotates in the forward direction is transmitted to the control component 3 through the mechanical structure. Unlocking is achieved after the control shaft 21 rotates in the forward direction, and after the movable member 91 is not controlled, the first electrical connection abutment 93 can be reset under the action of the first movable abutment 92 and the first spring 94, that is, it abuts against the second switch 43 again. At this time, locking is achieved after the control shaft 21 rotates in the reverse direction, thereby achieving a complete unlocking and locking function.

[0049] Further, a second accommodating groove 23 is further provided in the handle 2, the moving assembly 9 further includes a second moving resisting member 95, a second electrical connection resisting member 96 and a second spring 97, the magnetic attraction assembly 5 includes an electrical connection track 51, the moving member 91 abuts against the second moving resisting member 95, the second moving resisting member 95 is fixedly connected to the second electrical connection resisting member 96, the second electrical connection resisting member 96 is slidably connected in the second accommodating groove 23, the second electrical connection resisting member 96 is slidably connected to the electrical connection track 51, and the two ends of the second spring 97 are respectively fixedly connected to the inner wall of the second accommodating groove 23 and the second moving resisting member 95;

[0050] The covering assembly 8 includes a third spring 81 and a covering plate 82 . Two ends of the third spring 81 are fixedly connected to the covering plate 82 and the second movable abutment member 95 , respectively.

[0051] The second electrical connection abutment 96 has the same operating principle as the first electrical connection abutment 93, but the second electrical connection abutment 96 is always in contact with the electrical connection track 51, so the second circuit is always connected. In the advantageous case, both the magnetic attraction component 5 and the blocking component 7 can prevent the key from functioning in the mechanical component 6.

[0052] The third spring 81 serves as a connection buffer between the cover plate 82 and the second movable contact member 95, and there is a possibility of breakage. When the third spring 81 connection is broken, the second electrical connection contact member 96 cannot drive the cover plate 82 to move and needs to be repaired. The second electrical connection contact member 96 can be excessively moved to make the second electrical connection contact member 96 detach from the electrical connection track 51, thereby disconnecting the second circuit, so that the cover plate 82 can be moved normally.

[0053] Furthermore, the moving component 9 also includes a fingerprint recognition device 98 , which is installed on the moving component 91 .

[0054] The fingerprint recognition device 98 is a smart recognition device that can be electrically connected to the electronic control component 4 to transmit signals, or it can transmit signals by transmitting wireless signals.

[0055] Further, the mechanical assembly 6 includes a round-headed pin 61, a fourth spring 62, a sleeve 63, a connector 64 and a fifth spring 65. The control shaft 21 is provided with a connector slot 24, a lock hole 631 is provided in the sleeve 63, and a through hole 632 connecting the inside and outside of the lock hole 631 is provided on the sleeve 63. The handle 2 is also provided with a first accommodating chamber 25 and a second accommodating chamber 26. The connector 64 is slidably connected to the sleeve 63. The two ends of the fifth spring 65 are respectively fixedly connected to the connector 64 and the sleeve 63. The sleeve 63 is fixedly connected to the control shaft 21 and accommodated in the second accommodating chamber 26. The round-headed pin 61 is accommodated in the first accommodating chamber 25 and passes through the through hole 632 to enter the lock hole 631. The two ends of the fourth spring 62 are respectively fixedly connected to the round-headed pin 61 and the inner wall of the first accommodating chamber 25.

[0056] When the shape of the key inserted into the lock hole 631 matches the round pin 61 , the key pushes the connector 64 to move, and the connector 64 is accommodated in the connector slot 24 ;

[0057] When the key drives the sleeve 63 to rotate, the plug-in member 64 contacts the inner wall of the plug-in slot 24 and drives the control shaft 21 to rotate.

[0058] The mechanical assembly 6 can be regarded as a mechanical lock structure, and directly acts on the control shaft 21, and the round pin 61 plays the most basic role of matching the key shape. Since the specific operation form is the existing technology, it will not be described in detail;

[0059] In addition, since there is only one control shaft 21, in order to avoid conflict with the electronic control component 4, the connector 64 is accommodated in the connector slot 24 only by inserting the key, and the control shaft 21 is driven to rotate by the interference of the interference piece. When the key is not inserted, the connector 64 is not accommodated in the connector slot 24, so that the electronic control component 4 can drive the control shaft 21 to rotate normally.

[0060] Furthermore, the electronic control component 4 includes a motor 44, a transmission shaft 45, a first gear 46, a second gear 47 and a third gear 48. The transmission shaft 45 is connected to the motor 44, the transmission shaft 45 is fixedly connected to the first gear 46, the first gear 46 is meshingly connected to the second gear 47, the second gear 47 is meshingly connected to the third gear 48, and the third gear 48 is fixedly connected to the control shaft 21.

[0061] The electric control component 4 uses the motor 44 as a power source, and drives the control shaft 21 to rotate through the transmission shaft 45, the first gear 46, the second gear 47 and the third gear 48 in sequence, thereby achieving an electric control effect.

[0062] Further, the mechanical assembly 6 also includes a flat-headed pin 66, a sixth spring 67, a moving rod 68 and a seventh spring 69. The handle 2 is further provided with a third accommodating chamber 27 and a fourth accommodating chamber 28. The flat-headed pin 66 is accommodated in the third accommodating chamber 27. The flat-headed pin 66 abuts against the moving rod 68, and the abutting surface is an inclined surface. The moving rod 68 is fixedly connected to the second gear 47. The two ends of the sixth spring 67 are respectively fixedly connected to the flat-headed pin 66 and the inner wall of the third accommodating chamber 27. The second gear 47 is accommodated in the fourth accommodating chamber 28. The two ends of the seventh spring 69 are respectively fixedly connected to the second gear 47 and the inner wall of the fourth accommodating chamber 28.

[0063] When the shape of the key inserted into the lock hole 631 matches the round-head pin 61 , the key abuts against the flat-head pin 66 , and the flat-head pin 66 abuts against the moving rod 68 . The moving rod 68 drives the second gear 47 to move, and the second gear 47 is separated from the first gear 46 and the third gear 48 .

[0064] In order to prevent the electric control component 4 from affecting the use of the mechanical component 6, a moving rod 68 is provided to move the second gear 47. When the key is inserted, since the second gear 47 is moved away, even if the motor 44 is started, only the first gear 46 will idle. When the key is pulled out, the second gear 47 will be reset under the action of the seventh spring 69.

[0065] In addition, the moving principle of the flat-head pin 66 is the same as the moving principle of the round-head pin 61.

[0066] Furthermore, the magnetic attraction component 5 also includes an electromagnet 52, and the cover component 8 also includes a first magnetic block 83 and an eighth spring 84. A receiving groove 85 is provided in the cover plate 82, and the first magnetic block 83 is accommodated in the receiving groove 85. The two ends of the eighth spring 84 are respectively fixedly connected to the first magnetic block 83 and the inner wall of the receiving groove 85;

[0067] When the electromagnet 52 is energized, the first magnetic block 83 leaves the receiving groove 85 and contacts the handle 2 .

[0068] Furthermore, the blocking component 7 includes a second magnetic block 71 and a ninth spring 72, and both ends of the ninth spring 72 are fixedly connected to the handle 2 and the second magnetic block 71 respectively;

[0069] When the electromagnet 52 is energized, the second magnetic block 71 is received in the third receiving cavity 27 and contacts the flat-head pin 66 .

[0070] The electromagnet 52 needs to be able to play the necessary blocking role when energized, but considering the power consumption, the force applied to the pit person cannot be directly applied by magnetic force. Therefore, the force-bearing column is transferred by the first magnetic block 83 contacting the handle 2 and the second magnetic block 71 contacting the flat-headed pin 66. The magnetic force only plays the role of changing the direction of the force, which can greatly reduce power consumption.

[0071] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
