Description

Technical Field

[0001] The present application belongs to the technical field of electronic locks, and in particular, relates to a smart lock. Background Art

[0002] Smart locks are improved upon traditional mechanical locks and are more intelligent and simple in terms of user security, identification, and manageability. Smart locks are the executive components of locking doors in access control systems. Smart locks are different from traditional mechanical locks and are a type of composite lock.

[0003] The existing Chinese patent with publication number CN215212789U discloses an intelligent lock having a front handle with a first mounting cavity; the lock core includes a main body and a clutch cam; the first control component includes a first main control board built into the first mounting cavity and a first drive mechanism and a first drive transmission mechanism both built into the main body, the first main control board is electrically connected to the first drive mechanism, and the first drive transmission mechanism is driven by the first drive mechanism to drive the clutch cam to engage and disengage; the second control component includes a second main control board built into the first mounting cavity and a second drive mechanism and a second drive transmission mechanism both built into the main body, the second main control board is electrically connected to the second drive mechanism, and when the first control component is stationary, the second drive transmission mechanism is driven by the second drive mechanism to drive the clutch cam to engage and disengage.

[0004] Although the above-mentioned smart lock has two independent control components, which make its unlocking methods more diverse and safer and more convenient to use, the two sets of control components of the smart lock still require electric drive. When the power inside the smart lock is low or the motor is damaged, the two sets of control components will not work normally, the emergency capability is weak, and it does not have anti-drilling capability, and its safety is insufficient. Utility Model Content

[0005] The purpose of this application is to provide a smart lock to address the above-mentioned technical problems. When the power inside the smart lock is low or the motor is damaged, the lock can still be unlocked in an emergency, and an anti-drilling device is provided to prevent criminals from prying the lock with an electric drill, thereby making the smart lock more secure.

[0006] The present application provides a smart lock, including a housing, wherein the housing includes:

[0007] Emergency device, including lock cylinder and mechanical key socket;

[0008] An anti-drilling device, including an anti-drilling plate and a rotation stop block;

[0009] The locking bolt, including the toothed rack;

[0010] Output gear, which transmits power to the rack;

[0011] A first driving assembly, which transmits power to the output gear;

[0012] A second driving assembly, which transmits power to the output gear;

[0013] Among them, the lock core and the rack are transmitted, the rack and the housing are slidably connected, the anti-drilling plate and the lock core are rotationally connected, and the anti-rotation block and the anti-drilling plate are matched.

[0014] In the present technical scheme, an emergency device and an anti-drilling device are arranged on the shell, and a lock core and a mechanical key insertion hole are arranged in the emergency device. When the internal power of the intelligent lock is insufficient or the motor fails, the user inserts the key into the mechanical key insertion hole, and the lock core is rotated through the cooperation between the key and the lock core, and the lock core is transmitted with the rack on the lock tongue, so that the lock core drives the lock tongue to retract into the shell to unlock, so that the lock has an emergency function. When the intelligent component in the lock body has a problem, the user can still use the key for emergency unlocking, which provides convenience for the user. The anti-drilling device is provided with an anti-drilling plate and a stop block, which are rotatably connected to the lock core, and the user uses the key to unlock. When unlocking, the rotation of the key will not drive the anti-drill plate to rotate, and the anti-drill block cooperates with the anti-drill plate so that the anti-drill plate can be stably placed on the lock core. When lawless elements use a drill to pry the lock, the drill will damage the anti-drill plate. After the anti-drill plate is damaged, the cooperation between it and the anti-drill block is released, so that the anti-drill plate can rotate along the lock core. The drill rotates with the anti-drill plate, which can effectively prevent the drill from drilling into the lock core, thereby improving the anti-drill capability of the lock. A first drive assembly and a second drive assembly are also provided in the shell, wherein the first drive assembly and the second drive assembly are both transmitted to the output gear. The lock can be unlocked by two independent drive assemblies, has more unlocking methods, and is safer and more convenient to use.

[0015] Furthermore, the emergency device comprises:

[0016] Double-ended key, including pin;

[0017] An input gear connected to the lock cylinder;

[0018] A driven gear, which transmits power to the input gear;

[0019] A ratchet wheel fixedly connected to the driven gear;

[0020] A rotation-stopping pawl cooperates with the ratchet wheel;

[0021] A micro motor including a lead screw;

[0022] A limiter, including a pinhole and a card slot;

[0023] A push rod, including a push block and a buckle;

[0024] Among them, the limiter is rotationally connected to the micro motor, the pin and the pinhole are matched, the push rod and the pinhole are slidingly connected, the slot and the buckle are matched, the driven gear and the output gear are transmitted, and the screw rod and the anti-rotation pawl are matched.

[0025] The latch is then released and the latch is engaged, ... When unlocking, the first drive assembly and the second drive assembly will control the micromotor to rotate, the micromotor drives the screw rod to rotate, and the screw rod drives the anti-rotation pawl to move, releasing the cooperation between the anti-rotation pawl and the ratchet wheel, so that the output gear can rotate for unlocking. After the lock is locked, the micromotor reverses to make the anti-rotation pawl and the ratchet wheel cooperate again. When the user performs emergency unlocking through the mechanical key socket, the pin in the double-headed key is inserted into the pinhole in the limiter, and the pin pushes the push rod to release the cooperation between the buckle and the slot, so that the push rod slides in the pinhole, and the push block is pushed and rotated by the push rod to push the limiter out of the shell, and at the same time, the cooperation between the anti-rotation pawl and the ratchet wheel is released, so that the output gear can rotate for emergency unlocking. After unlocking is completed, the user presses down the limiter to make the buckle and the slot cooperate, and the anti-rotation pawl and the ratchet wheel cooperate again. The position of the pinhole is relatively hidden, and it is difficult for lawless elements who are not familiar with the lock to pry the lock, which greatly improves the safety of the lock.

[0026] Furthermore, the anti-drilling device comprises:

[0027] A return spring connected to the anti-rotation block;

[0028] buzzer;

[0029] A relay connected between the stop block and the buzzer;

[0030] Wherein, the shell is provided with a permanent magnet, and the anti-rotation block is connected with the permanent magnet after being energized.

[0031] In the present technical scheme, a reset spring, a buzzer and a relay are arranged in the anti-drill device, and the anti-drill block is made of electromagnetic material and a permanent magnet is arranged on the shell. When the criminals destroy the lock with a drill bit, the anti-drill plate will be destroyed by the drill bit first due to its position. After the anti-drill plate is destroyed, the relay is triggered to work, and the relay energizes the anti-drill block and the buzzer. After the anti-drill block is energized, it is connected to the permanent magnet. At this time, the coordination between the anti-drill block and the anti-drill plate is released, so that the anti-drill plate can rotate on the lock core, that is, the drill bit rotates with the anti-drill plate, making it difficult for the drill bit to drill into the lock core, thereby improving the anti-drill performance of the lock. At the same time, the buzzer alarms after being energized, which can alert the criminals and remind the user that the lock is damaged. Therefore, the lock has an alarm function.

[0032] Furthermore, the housing further comprises:

[0033] A fingerprint identifier connected to the first driving component;

[0034] A card reader connected to the first driving assembly;

[0035] A button is connected to the second driving component.

[0036] In the present technical solution, a fingerprint identifier, a card reader and a button are installed on the outer surface of the shell, wherein the fingerprint identifier and the card reader are connected to the first drive component, and the user activates the first drive component by swiping the card or inputting the fingerprint to unlock the lock, and the button is connected to the second drive component, and the user inputs the correct password by pressing the button to activate the second drive component to unlock the lock. Combined with the above technical features, the lock has more unlocking methods and can be used more conveniently.

[0037] Furthermore, the limiter is provided with a dust cover;

[0038] Wherein, the dust cover cooperates with the pinhole.

[0039] In the present technical solution, a dust cover is rotatably connected to the limiter, and the dust cover cooperates with the pinhole. The dust cover can effectively prevent dust from entering the pinhole, avoiding clogging of the pinhole and affecting the cooperation between the pin and the pinhole. The dust cover can conceal the position of the pinhole, thereby improving the safety of the lock.

[0040] Furthermore, the housing further comprises:

[0041] An inner handle connected to the lock core and rotatably connected to the housing;

[0042] An outer handle is fixedly connected to the shell.

[0043] In the present technical solution, an inner handle and an outer handle are arranged on the shell, and the inner handle is placed indoors and is connected to the lock cylinder and is rotatably connected to the shell. When the user is indoors, there is no need to press the limiter into the shell, that is, the ratchet is not affected by the anti-rotation pawl and can rotate, so that the user can unlock the door by rotating the inner handle. The outer handle is placed outdoors and is fixedly connected to the shell. The user can effectively control the force of opening and closing the door through the outer handle, thereby reducing the noise when opening and closing the door.

[0044] The beneficial effects of this application are:

[0045] 1. The lock core is rotated by the cooperation between the key and the lock core, and the lock core drives the lock tongue to retract into the shell to unlock, so that the lock has an emergency function. When the lock is pried with a drill, the drill will damage the anti-drill plate, release the cooperation between the anti-drill plate and the anti-rotation block, and make the drill rotate with the anti-drill plate to prevent the drill from drilling into the lock core, thereby improving the anti-drilling ability of the lock.

[0046] 2. When the ratchet and the anti-rotation pawl cooperate, the ratchet can be prevented from rotating in one direction, so that the ratchet can only rotate in the opposite direction to facilitate locking. The output gear cannot rotate after being locked to prevent criminals from prying the lock. When the first drive component and the second drive component are unlocked, the micro motor can be controlled to rotate, and the micro motor drives the anti-rotation pawl to move, releasing the cooperation between the anti-rotation pawl and the ratchet, so that the output gear can rotate. When emergency unlocking, insert the pin into the pinhole to push the push rod, so that the push rod pushes the limiter out, releasing the cooperation between the anti-rotation pawl and the ratchet, so that the output gear can rotate, thereby improving the safety of the lock.

[0047] 3. When the lock is damaged by a drill, the anti-drill plate will be damaged first and trigger the relay to work. The relay triggers the anti-rotation block and the buzzer to be energized. After the anti-rotation block is energized, it is connected with the permanent magnet, so that the anti-drill plate can rotate on the lock core. The drill bit rotates with the anti-drill plate, making it difficult for the drill bit to drill into the lock core. At the same time, the buzzer alarms, thereby improving the anti-drill performance of the lock. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0057] Embodiment 1:

[0058] like Figure 1-5 As shown, the embodiment of the present application provides a smart lock, including a housing 100, wherein the housing 100 includes:

[0059] The emergency device 200 includes a lock cylinder 210 and a mechanical key insertion hole 220;

[0060] The anti-drilling device 300 includes an anti-drilling plate 310 and a rotation-stopping block 320;

[0061] The locking tongue 400 includes a rack 410;

[0062] An output gear 500, which transmits power to the rack 410;

[0063] A first driving assembly 600, which transmits power to the output gear 500;

[0064] A second driving assembly 700, which transmits power to the output gear 500;

[0065] The lock core 210 and the rack 410 are transmitted, the rack 410 and the housing 100 are slidably connected, the anti-drilling plate 310 and the lock core 210 are rotationally connected, and the anti-rotation block 320 cooperates with the anti-drilling plate 310 .

[0066] By arranging an emergency device 200 and an anti-drilling device 300 on the housing 100, a lock core 210 and a mechanical key insertion hole 220 are arranged in the emergency device 200. When the power inside the smart lock is insufficient or the motor fails, the user inserts the key into the mechanical key insertion hole 220, and rotates the lock core 210 through the cooperation between the key and the lock core 210. The lock core 210 is in turn transmitted with the rack 410 on the lock tongue 400, so that the lock core 210 drives the lock tongue 400 to retract into the housing 100 for unlocking, so that the lock has an emergency function. When the smart component in the lock body has a problem, the user can still use the key for emergency unlocking, which provides convenience for the user. The anti-drilling device 300 is provided with an anti-drilling plate 310 and a stop block 320. The anti-drilling plate 310 is rotatably connected to the lock core 210, and the user uses the key to When unlocking, the rotation of the key will not drive the anti-drill plate 310 to rotate, and the anti-drill block 320 cooperates with the anti-drill plate 310, so that the anti-drill plate 310 can be stably placed on the lock core 210. When criminals use a drill to pry the lock, the drill will damage the anti-drill plate 310. After the anti-drill plate 310 is damaged, the cooperation between it and the anti-drill block 320 is released, so that the anti-drill plate 310 can rotate along the lock core 210. The drill rotates with the anti-drill plate 310, which can effectively prevent the drill from drilling into the lock core 210, thereby improving the anti-drilling ability of the lock. A first drive assembly 600 and a second drive assembly 700 are also provided in the housing 100, wherein the first drive assembly 600 and the second drive assembly 700 are both transmitted to the output gear 500. The lock can be unlocked by two sets of independent drive assemblies, has more unlocking methods, and is safer and more convenient to use.

[0067] Furthermore, the emergency device 200 includes:

[0068] A double-ended key 201, including a pin 202;

[0069] An input gear 230 connected to the lock cylinder 210;

[0070] A driven gear 240, which transmits power to the input gear 230;

[0071] A ratchet 250, which is fixedly connected to the driven gear 240;

[0072] A rotation-stopping pawl 260 cooperates with the ratchet wheel 250;

[0073] A micro motor 270, comprising a screw rod 271;

[0074] The stopper 280 includes a pinhole 281 and a card slot 282;

[0075] The ejector rod 290 includes an ejector block 291 and a buckle 292;

[0076] Among them, the limiter 280 is rotationally connected to the micro motor 270, the pin 202 is matched with the pinhole 281, the push rod 290 is slidingly connected to the pinhole 281, the slot 282 is matched with the buckle 292, the driven gear 240 is transmitted to the output gear 500, and the screw rod 271 is matched with the anti-rotation pawl 260.

[0077] By setting an input gear 230 and a driven gear 240 in the emergency device 200, the input gear 230 is connected to the lock core 210, the driven gear 240 and the input gear 230 are transmitted, and the driven gear 240 and the output gear 500 are transmitted. When emergency unlocking is performed, the user inserts the double-headed key 201 into the lock core 210, rotates the lock core 210 to drive the input gear 230 to rotate, the input gear 230 drives the output gear 500 to rotate through the transmission, and the output gear 500 drives the rack 410 to move, so that the lock tongue 400 is retracted into the housing 100 to unlock, and the limiter 280 and the output gear 500 are set in the emergency device 200. The anti-rotation pawl 260 and the limiter 280 are rotatably connected to a micro motor 270 with a screw rod 271, and the screw rod 271 cooperates with the anti-rotation pawl 260. At the same time, a ratchet 250 is fixedly connected to the driven gear 240. When the ratchet 250 and the anti-rotation pawl 260 cooperate, the ratchet 250 can be prevented from rotating in one direction, and the ratchet 250 can still rotate in the opposite direction, so that the lock tongue 400 extends out of the housing 100 and is locked, so that the output gear 500 cannot rotate after being locked, thereby preventing criminals from picking the lock at the mechanical key insertion hole 220, and the user unlocks the lock through the first drive assembly 600 and the second drive assembly 700. When locking, the first drive assembly 600 and the second drive assembly 700 will control the micro motor 270 to rotate, the micro motor 270 drives the screw rod 271 to rotate, and the screw rod 271 drives the anti-rotation pawl 260 to move, releasing the cooperation between the anti-rotation pawl 260 and the ratchet 250, so that the output gear 500 can rotate to unlock. After the lock is locked, the micro motor 270 reverses to make the anti-rotation pawl 260 and the ratchet 250 cooperate again. When the user performs emergency unlocking through the mechanical key socket 220, the pin 202 in the double-headed key 201 is inserted into the pinhole 281 in the limiter 280, and the pin 202 pushes the top rod 290. , the cooperation between the buckle 292 and the slot 282 is released, so that the push rod 290 slides in the pinhole 281, and the push block 291 is pushed and rotated by the push rod 290, pushing the limiter 280 out of the shell 100, and at the same time, the cooperation between the anti-rotation pawl 260 and the ratchet 250 is released, so that the output gear 500 can rotate for emergency unlocking. After unlocking is completed, the user presses down the limiter 280 to make the buckle 292 cooperate with the slot 282, and at the same time, the anti-rotation pawl 260 and the ratchet 250 cooperate again. The position of the pinhole 281 is relatively secret, and it is difficult for criminals who are not familiar with the lock to pry the lock, which greatly improves the security of the lock.

[0078] Furthermore, the anti-drilling device 300 includes:

[0079] A return spring 330 connected to the anti-rotation block 320;

[0080] Buzzer 340;

[0081] A relay 350 connected between the anti-rotation block 320 and the buzzer 340;

[0082] The housing 100 is provided with a permanent magnet 110 , and the anti-rotation block 320 is connected to the permanent magnet 110 after being energized.

After the anti-drilling plate 310 is destroyed, the relay 350 is triggered to work, and the relay 350 energizes the anti-drilling block 320 and the buzzer 340. After the anti-drilling block 320 is energized, it is connected with the permanent magnet 110. At this time, the cooperation between the anti-drilling block 320 and the anti-drilling plate 310 is released, so that the anti-drilling plate 310 can rotate on the lock core 210, that is, the drill bit rotates with the anti-drilling plate 310, making it difficult for the drill bit to drill into the lock core 210, thereby improving the anti-drilling performance of the present lock. At the same time, the buzzer 340 alarms after being energized, which can warn the criminals and remind the user that the lock is damaged. This means that the present lock has an alarm function.

[0089] A fingerprint identifier 120, a card reader 130 and a button 140 are installed on the outer surface of the shell 100, wherein the fingerprint identifier 120 and the card reader 130 are both connected to the first drive component 600, and the user swipes the card or inputs the fingerprint to make the first drive component 600 work to unlock the lock, and the button 140 is connected to the second drive component 700, and the user inputs the correct password through the button 140 to make the second drive component 700 work to unlock the lock. Combined with the above technical features, the lock has more unlocking methods and can be used more conveniently.

[0090] Further, the stopper 280 is provided with a dust cover 283;

[0091] The dust cover 283 is matched with the pinhole 281 .

[0092] A dust cover 283 is rotatably connected to the limiter 280, and the dust cover 283 cooperates with the pinhole 281. The dust cover 283 can effectively prevent dust from entering the pinhole 281, avoiding clogging of the pinhole 281 and affecting the cooperation between the pin 202 and the pinhole 281. The dust cover 283 can conceal the position of the pinhole 281, thereby improving the safety of the lock.

[0093] Furthermore, the housing 100 further includes:

[0094] An inner handle 150 connected to the lock cylinder 210 and rotatably connected to the housing 100;

[0095] The outer handle 160 is fixedly connected to the housing 100 .

[0096] By arranging an inner handle 150 and an outer handle 160 on the shell 100, the inner handle 150 is placed indoors and is connected to the lock cylinder 210 and is rotatably connected to the shell 100. When the user is indoors, there is no need to press the limiter 280 into the shell 100, that is, the ratchet 250 is not affected by the anti-rotation pawl 260 and can rotate, so that the user can unlock the door by rotating the inner handle 150. The outer handle 160 is placed outdoors and is fixedly connected to the shell 100. The user can effectively control the force of opening and closing the door through the outer handle 160, thereby reducing the noise when opening and closing the door.

[0097] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
