[0033] This utility model provides an intelligent emergency lock cylinder and lock, which integrates both mechanical and electronic emergency unlocking methods, thereby improving the ease and reliability of emergency unlocking operations and making it applicable to a variety of locks.

[0034] like Figures 1 to 4 As shown, this embodiment of the utility model provides an intelligent emergency lock cylinder 100, which includes: a lock housing 140, an electronic emergency unlocking module 110, a mechanical emergency unlocking module 120, and an unlocking / locking module 130. The electronic emergency unlocking module 110, the mechanical emergency unlocking module 120, and the unlocking / locking module 130 are disposed inside the lock housing 140. The lock housing 140 not only protects the internal modules from damage but also provides necessary support for each module. The electronic emergency unlocking module 110 includes a control unit 111, a drive assembly 112, and a Type-C data port 113. The data port 113 is exposed outside the lock 200, allowing it to be electrically connected to an external control device (such as a mobile phone). The data port 113 is electrically connected to the control unit 111, and the control unit 111 is electrically connected to the drive assembly 112 and can supply power to the drive assembly 112. By integrating the mechanical emergency unlocking module 120 and the electronic emergency unlocking module 110 into the intelligent emergency lock cylinder 100, the intelligent emergency lock cylinder 100 can realize both mechanical and electronic emergency unlocking methods, which facilitates the integration of electromechanical unlocking. Both the mechanical emergency unlocking module 120 and the drive component 112 can drive the locking / unlocking module 130 to move, thereby enabling the lock 200 to perform either mechanical or electronic emergency unlocking.

[0035] This utility model's technical solution integrates a mechanical emergency unlocking module 120 and an electronic emergency unlocking module 110 into the intelligent emergency lock cylinder 100. Both modules are connected to the unlocking / locking module 130. Users only need to carry either a mechanical unlocking key or an external control device to achieve emergency unlocking. This allows for both mechanical and electronic emergency unlocking, ensuring reliable unlocking in different emergency scenarios. This improves the versatility and compatibility of the intelligent emergency lock cylinder 100. The intelligent emergency lock cylinder 100 has a compact internal structure and small size, making it applicable to various lock scenarios.

[0036] like Figure 2 As shown, the electronic emergency unlocking module 110 also includes a power supply line 114. The power supply line 114 can be electrically connected to an external power supply device (such as a mobile phone or power bank) through the data port 113. The external power supply device can supply power to the lock. In this utility model, the electronic emergency unlocking module 110 also includes a power supply line 114. When the user carries an external power supply device, the power supply line 114 can be electrically connected to the external power supply device, which can supply power to the lock 200. This allows for emergency unlocking of the lock 200 after identity recognition, which is beneficial for reliable unlocking in different emergency scenarios, thereby improving the versatility and compatibility of the smart emergency lock cylinder.

[0037] like Figures 2 to 4 As shown, in this embodiment, the locking / unlocking module 130 includes: a first clutch pin 131 and a second clutch pin 133 symmetrically arranged, and a rotating shaft 132. The rotating shaft 132 includes a slot 1321 for the first clutch pin 131 and the second clutch pin 133 to extend into or retract. The first clutch pin 131 is connected to the rotating ear 121, and the second clutch pin 133 is connected to the drive assembly 112.

[0038] like Figures 1 to 4 As shown, the intelligent emergency lock cylinder 100 also includes a rear cover 150. The rear cover 150 is connected to the lock housing 140 and is used to seal the lock housing 140. The rear cover 150 includes a mounting hole 151, and a first clutch pin 131 and a second clutch pin 133 are disposed within the mounting hole 151. The rear cover 150 not only protects and supports the internal modules, but also provides a precise limiting function for the locking / unlocking module 130, which helps to improve the accuracy of the locking / unlocking process.

[0039] like Figures 2 to 4As shown, the first clutch pin 131 includes a first part 1311 and a second part 1312 connected to each other. The first part 1311 can extend into the slot 1321 through the mounting hole 151. The second clutch pin 133 includes a third part 1331 and a fourth part 1332 connected to each other. The third part 1331 can extend into the slot 1321 through the mounting hole 151. This utility model's technical solution, by setting a clutch pin and a rotating shaft 132, with the rotating shaft 132 including a slot 1321 for the clutch pin to extend into or retract, and at least a portion of the clutch pin's structure being able to extend into or retract from the slot 1321, forms a mating connection and synchronous rotation between the lock housing 140 and the rotating shaft 132. It is understood that, preferably, the first part 1311 and the second part 1312 have arc-shaped guide surfaces, which facilitate insertion into or removal from the slot 1321. The inner wall of the slot 1321 of the rotating shaft 132 is also an arc-shaped groove, which is adapted to the arc-shaped guide surfaces of the first part 1311 and the second part 1312.

[0040] like Figures 2 to 3 As shown, the mechanical emergency unlocking module 120 includes a rotating lug 121 and a limiting part 122. The rotating lug 121 is connected to the mechanical unlocking key. The limiting part 122 protrudes from the surface of the rotating lug 121 and can abut against the first clutch pin 131.

[0041] like Figures 2 to 4 As shown, the second part 1312 and the fourth part 1332 are respectively fitted with elastic elements 134, which provide elastic restoring force for the first clutch pin 131 and the second clutch pin 133. Preferably, the elastic element 134 is in the form of a tower spring, which helps to prevent the first clutch pin 131 and the second clutch pin 133 from getting stuck in the gap between the rotating shaft 132 and the lock housing 140 during movement.

[0042] In this embodiment, the intelligent emergency lock cylinder 100 has a normal locking state and an emergency unlocking state. In the normal locking state, the mechanical emergency unlocking module 120 and the drive assembly 112 are both separated from the corresponding clutch pins. The first part 1311 and the third part 1331 are removed from the slot 1321. The first clutch pin 131 and the second clutch pin 133 disconnect the lock housing 140 from the rotating shaft 132, and the lock housing 140 rotates freely relative to the rotating shaft 132.

[0043] In the emergency unlocking state, the mechanical emergency unlocking module 120 abuts against the first clutch pin 131 to drive the first clutch pin 131 to move, or the drive assembly 112 abuts against the second clutch pin 133 to drive the second clutch pin 133 to move, so that the first part 1311 or the third part 1331 can extend from the mounting hole 151 into the slot 1321. The first clutch pin 131 is restricted by the limiting part 122 and cannot move, or the second clutch pin 133 is restricted by the drive shaft 1122 and cannot move, so that the first clutch pin 131 or the second clutch pin 133 is stuck between the mounting hole 151 and the slot 1321, so as to drive the lock housing 140 and the rotating shaft 132 to rotate synchronously.

[0044] In this embodiment, the emergency unlocking state includes electronic emergency unlocking state, power supply emergency unlocking state, and mechanical emergency unlocking state.

[0045] In the electronic emergency unlocking state, the Type-C data port 113 is connected to an external control device (such as a mobile phone), and the mobile phone application software is opened. The mobile phone application software sends an unlocking signal to the control unit 111 through the data port 113. The control unit 111 receives the unlocking signal and can supply power to the drive component 112 to drive the third part 1331 to extend into the slot 1321 to electronically unlock the lock 200.

[0046] In the emergency power unlocking state, the power supply line 114 is connected to an external power supply device (such as a mobile phone or power bank), which can supply power to the lock 200 to enable emergency power unlocking of the lock 200.

[0047] It is understood that the data port 113 form, external control device form, and external power supply device form mentioned above are only one preferred embodiment. Those skilled in the art can also choose a suitable data port 113 form, external control device form, and external power supply device form according to the actual situation. This application does not limit them.

[0048] In the mechanical emergency unlocking state, inserting and turning the mechanical key causes the lug 121 to rotate. The limiting part 122 abuts against the first clutch pin 131 and pushes the first part 1311 into the slot 1321 to mechanically unlock the lock 200. In this embodiment, the mechanical emergency unlocking module 120 is also equipped with multiple sets of mechanical lock plates, authorized pins, and auxiliary magnetic components. Only when the preset mechanical key is correctly matched can the lug 121 rotate accurately so that its limiting part 122 engages with the first clutch pin 131, effectively ensuring the security of the mechanical emergency unlocking of the lock 200.

[0049] like Figure 4As shown, in this embodiment, the rotation axis of the rotating shaft 132 is collinear with the rotation axis of the lock housing 140. This invention, by aligning the rotation axis of the rotating shaft 132 with the rotation axis of the lock housing 140, ensures that the lock housing 140 and the rotating shaft 132 rotate synchronously during locking and unlocking, guaranteeing overall linkage when the door handle rotates, thereby achieving a stable locking or unlocking state.

[0050] like Figure 4 As shown, the drive assembly 112 includes a drive unit 1121 and a drive shaft 1122, and the control unit 111 is electrically connected to the drive unit 1121. The drive unit 1121 can drive the drive shaft 1122 to extend and retract. When the drive shaft 1122 extends, it can restrict the movement of the second clutch pin 133, allowing the third part 1331 to extend into the slot 1321. Preferably, the drive unit 1121 is a solenoid and the drive shaft 1122 is an iron core. In the normal locked state, the drive unit 1121 is de-energized, the iron core retracts, and separates from the second clutch pin 133. In the normal unlocked or emergency unlocked state, the solenoid is powered, the iron core extends, restricting the movement of the second clutch pin 133, allowing the third part 1331 to extend into the slot 1321. The present invention provides a driving unit 1121 and a driving shaft 1122. The driving unit 1121 can drive the driving shaft 1122 to extend and retract, thereby precisely controlling the third part 1331 to extend into or exit the slot 1321, thus enabling the intelligent emergency lock cylinder 100 to switch between normal locking and emergency unlocking states.

[0051] like Figure 2 As shown, the back cover 150 includes a channel 151 and a sealing structure 152. The channel 151 allows the power supply line 114 to pass through, and the sealing structure 152 seals the channel 151. This invention, by providing a sealing structure 152 on the back cover 150, helps prevent external water, dust, or other contaminants from entering the lock housing 140, thus extending the service life of the modules inside the lock housing 140. Preferably, the sealing structure 152 is a rubber sealing plug. In other embodiments, a protective cover or other protective structure can also be provided outside the data port 113 to avoid collisions or contamination, thereby extending the service life of the data port 113.

[0052] like Figure 5As shown, this embodiment of the present invention also provides a lock 200. The lock 200 includes: an intelligent emergency lock cylinder 100 according to any of the foregoing embodiments of the present invention, a door handle 210, a main control unlocking module 220, an identification module (not shown), and a connecting shaft 230. The door handle 210 is connected to the lock housing 140 of the intelligent emergency lock cylinder 100 and rotates synchronously. The main control unlocking module 220 is electrically connected to a power supply line 114, which provides power to the main control unlocking module 220. The identification module is electrically connected to the main control unlocking module 220. The connecting shaft 230 is connected between the main control unlocking module 220 and the door lock body. After the intelligent emergency lock cylinder 100 is unlocked, rotating the door handle 210 can drive the lock housing 140 and the rotating shaft 132 of the intelligent emergency lock cylinder 100 to rotate synchronously, thereby driving the connecting shaft 230 to rotate, thus unlocking the lock 200.

[0053] This utility model's technical solution incorporates an intelligent emergency lock cylinder 100, a door handle 210, a main control unlocking module 220, an identification module, and a connecting shaft 230 within a lock 200. The intelligent emergency lock cylinder 100 integrates a mechanical emergency unlocking module 120 and an electronic emergency unlocking module 110, both of which are connected to the unlocking / locking module 130. Users only need to carry either a mechanical unlocking key or an external control device to achieve emergency unlocking. This allows for both mechanical and electronic emergency unlocking, ensuring reliable unlocking in various emergency scenarios and improving the versatility and compatibility of the intelligent emergency lock cylinder 100. The intelligent emergency lock cylinder 100 has a compact internal structure and small size, enabling its application in different lock 200 scenarios.

[0054] In this embodiment, the main control unlocking module 220 has the function of directly accepting power from external power sources such as mobile phones and power banks through the power supply line 114, and is electrically connected to the identity recognition module for linkage. The main control unlocking module 220 can only be powered on and unlocked after the identity recognition module has passed the authentication methods such as fingerprint, password, and face.

[0055] In this embodiment, rotating the door lock handle 210 can drive the lock housing 140 and the rotating shaft 132 of the smart emergency lock cylinder 100 to rotate synchronously, thereby driving part of the unlocking structure in the main control unlocking module 220 and the connecting shaft 230 to rotate, so as to unlock the lock 200. It should be noted that in other embodiments, after emergency unlocking, rotating the door lock handle 210 may also drive the connecting shaft 230 to rotate without going through the main control unlocking module 220. This application does not limit the specific transmission connection method between the door lock handle 210 and the connecting shaft 230. Those skilled in the art can set the emergency unlocking method between the door lock handle 210 and the connecting shaft 230 according to actual needs.

[0056] The normal locking state and three different emergency unlocking states of the lock 200 in this embodiment will be described next.

[0057] In the normal locked state, the rotating lug 121 of the mechanical emergency unlocking module 120 is in its initial position, the limiting part 122 is separated from the first clutch pin 131, and simultaneously the drive shaft 1122 in the electronic emergency unlocking module 110 is in a retracted state and is also separated from the second clutch pin 133. The first part 1311 and the third part 1331 exit the slot 1321, and the first clutch pin 131 and the second clutch pin 133 disconnect the lock housing 140 from the rotating shaft 132, causing the lock housing 140 and the rotating shaft 132 to be in a relatively free-spinning state. At this time, when the door lock handle 210 is turned, the door lock handle 210 drives the lock housing 140 to rotate, but cannot drive the rotating shaft 132 to rotate, so it cannot drive the main unlocking module 220 to unlock. Thus, the lock 200 is in the normal locked state.

[0058] In the mechanical emergency unlocking state, the user inserts a preset mechanical key and rotates the mechanical emergency unlocking module 120, causing the lug 121 to rotate and the limiting part 122 to abut against the first clutch pin 131. This pushes the first part 1311 from the mounting hole 151 into the slot 1321, so that the first clutch pin 131 is locked between the mounting hole 151 and the slot 1321, thereby driving the lock housing 140 and the rotating shaft 132 to rotate synchronously. At this time, rotating the door lock handle 210 causes the door lock handle 210 to rotate the lock housing 140, which in turn drives the rotating shaft 132 to rotate, thereby driving the main control unlocking module 220 and the connecting shaft 230 to unlock the lock 200.

[0059] In the electronic emergency unlocking state, the user connects an external control device (such as a mobile phone) to the data port 113. The external control device sends an unlock / lock signal to the control unit 111 through the data port 113 and supplies power to the control unit 111. The control unit 111 receives the unlock / lock signal and supplies power to the drive assembly 112. The drive shaft 1122 is energized and extends to restrict the movement of the second clutch pin 133, causing the third part 1331 of the second clutch pin 133 to extend into the slot 1321. This causes the second clutch pin 133 to be engaged between the mounting hole 151 and the slot 1321, thereby driving the lock housing 140 and the rotating shaft 132 to rotate synchronously. At this time, turning the door lock handle 210 causes the door lock handle 210 to rotate, which in turn causes the lock housing 140 to rotate. The lock housing 140 then rotates the rotating shaft 132, thereby driving the main control unlocking module 220 and the connecting shaft 230 to unlock the lock 200.

[0060] In emergency unlocking mode, the user connects an external power supply device (such as a mobile phone or power bank) to the power supply line 114. The external power supply device can supply power to the main control unlocking module 220 and the identity recognition module. After the identity authentication module verifies the identity, the user turns the door lock handle 210. The door lock handle 210 drives the lock housing 140 to rotate, and the lock housing 140 drives the rotating shaft 132 to rotate, thereby driving the main control unlocking module 220 and the connecting shaft 230 to unlock the lock 200.

[0061] This utility model integrates the mechanical emergency unlocking module 120 and the electronic emergency unlocking module 110 into the intelligent emergency lock cylinder 100. The intelligent emergency lock cylinder 100 can connect to external control devices and external power supply devices, and can also be mechanically unlocked in an emergency using a mechanical unlocking key. These three emergency unlocking modes can operate independently. Users only need to carry one of the mechanical unlocking key, external control device, or external power supply device to achieve emergency unlocking. The intelligent emergency lock cylinder 100 has a compact internal structure and small size, which is beneficial for application in different lock scenarios 200, improving compatibility.

[0062] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
