Description

Technical Field

[0001] The utility model relates to a lock, in particular to an intelligent lock and an intelligent lock system. Background Art

[0002] In the field of smart locks, most of the smart locks on the market are stand-alone locks, which cannot realize the centralized management and hierarchical management of batch smart locks. In the field of smart lock networking, the smart locks on the market are all connected to WiFi, or private protocols such as Bluetooth and LORA. In the field of access control management, all management methods are to add door magnets. Insufficient security: Traditional access control systems may use keys or access cards that are easy to copy or lose, which poses a security risk. Smart door locks and hinges use advanced authentication technology and encryption algorithms to provide a higher level of security to prevent unauthorized access. Key management issues: Traditional key management requires a large number of physical keys and access cards, which are easy to lose, stolen or need to be replaced regularly. Smart door locks and hinges eliminate the reliance on traditional keys. Through digital access methods, users can use smartphones or other authorized devices as virtual keys for easy management and use. Lack of real-time monitoring and alarm: Traditional access control systems are usually unable to monitor the status of the door in real time, and it is difficult to detect abnormal events in time, such as the door being forced open or damaged. Smart door locks and hinges provide real-time monitoring and alarm functions. Administrators can receive alerts immediately and take appropriate measures, which enhances security and responsiveness. Inefficient access rights management: Traditional access control systems require manual management of access cards or keys, which is prone to improper management, omissions or errors. The combination of smart door locks and hinges provides flexible access rights management through a software interface. Administrators can easily add, delete or modify user permissions, which improves management efficiency and accuracy. Difficulties in data recording and analysis: Traditional access control systems are usually unable to record and store detailed access event information, making subsequent audits and analysis difficult. Smart door locks and hinges record all switch events, authorizations and alarm information, and provide data storage and analysis functions to help administrators understand the use of doors, identify potential security issues, and make corresponding improvements and optimizations.

[0003] In the field of construction, fire is a serious safety threat that can lead to the loss of life and property. When a fire breaks out, flames and smoke can spread quickly, hindering people's escape and providing rescue workers with access to the building. Therefore, in order to ensure that people can escape safely in the event of a fire and provide better conditions for rescue work, countries have formulated a series of building codes and safety standards. Fire doors and fire locks are widely used as one of the important components of building safety. Fire doors have special materials and structural designs that can resist the intrusion of flames and smoke for a certain period of time, thereby providing people with enough time to escape from the fire scene. However, an ordinary door lock may not be able to maintain the integrity of the door in a fire, as the fire may render the door lock ineffective or damaged. Therefore, a special lock is needed to ensure the effectiveness of fire doors in a fire.

[0004] Traditional fireproof locks are mechanical locks, which do not have intelligent control functions, alarm and management functions. At present, most fireproof locks only have a single function of opening and closing with a mechanical key, which is a single function.

DETAILED DESCRIPTION

[0057] The following is a detailed description of the implementation of the utility model. It should be emphasized that the following description is only exemplary and is not intended to limit the scope and application of the utility model.

[0058] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, connection can be used for fixing as well as for coupling or communication.

[0059] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0060] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0061] See also Figures 1 to 8 The embodiment of the utility model provides a smart lock, including a lock body lower panel 1, a lock body upper panel 2, a lock tongue 4, an outer handle 601, an inner handle 602, a handle restriction structure and a driving mechanism, wherein the lock tongue 4 is arranged between the lock body lower panel 1 and the lock body upper panel 2, the outer handle 601 and the inner handle 602 are respectively used to install an outer handle and an inner handle, the outer handle 601 and the inner handle 602 are respectively coupled to the lock tongue 4, the driving mechanism is connected to the handle restriction structure to control it to switch between a first state and a second state, when the handle restriction structure is in the first state, the rotation of the outer handle 601 is restricted to prevent the outer handle 601 from driving the lock tongue 4, and when the handle restriction structure is in the second state, the rotation of the outer handle 601 is released.

[0062] The utility model arranges a lock tongue inside the smart lock, and the lock tongue is controlled by an inner handle and an outer handle. A driving mechanism (such as a solenoid valve) is arranged below the lock tongue. The driving mechanism can control the working state of the outer handle by switching the state of the handle restriction structure. In normal use, the door cannot be opened from the outside only by the outer handle, thereby ensuring the safety effect of the smart lock.

At this time, the outer handle 601 cannot rotate, and the lock tongue 4 can only be controlled from the inside through the inner handle 602.

[0083] When it is necessary to use the external handle 601 to control the lock tongue 4, the electromagnetic valve 5 drives the connecting plate 501 to retract, and the connecting plate 501 drives the handle limit plate 502 and the limit seat 503 to retract. At this time, the limit seat 503 is separated from the limit block 605, and the limit of the external handle 601 is released. By rotating the external handle 601 to make the lever 603 squeeze the lever plate 403, the lock tongue 4 can be controlled. When the electromagnetic valve 5 fails under extreme conditions, the lock head 7 is controlled by the emergency key to make the swing arm 701 at one end of the lock head 7 rotate, and when the swing arm 701 rotates to the pressure plate 803, it squeezes the pressure plate 803 downward, so that the pressure plate 803 drives the locking rod 8 to rotate, and the locking rod 8 drives the movable arm 802 to rotate, so that the bottom end of the movable arm 802 drives the lever plate 403, so that the lever plate 403 drives the lock rod 401 to slide, thereby achieving control of the lock tongue 4.

[0084] When the smart lock is closed, the user pushes the plug rod 405 through the protrusion in the room, so that the plug rod 405 slides horizontally. At this time, the positioning block 410 on the plug rod 405 squeezes the arc surface on one side of the baffle 409, so that the baffle 409 and the positioning rod 408 move upward. At the same time, the plug rod 405 drives the safety tongue 407 to move outward through the transition plate 406, so that the safety tongue 407 extends outward. After the plug rod 405 moves a certain distance, the positioning block 410 moves to the other side of the baffle 409. At this time, the baffle 409 locks the position of the positioning block 410. At this time, the safety tongue 407 remains in the extended state. At this time, the transition plate 406 is separated from the safety tongue detection switch 10. At this time, the central processing unit module in the smart lock can detect The state of the safety tongue 407 is detected to control the electromagnetic valve 5, so that the external handle 601 can be controlled. At this time, the door cannot be opened from the outside, but by rotating the inner handle 602, the inner handle 602 drives the dial plate 403 to move, and the dial plate 403 drives the lock tongue 4 to move, so that the door can be opened. At the same time, the positioning rod 408 is squeezed during the movement of the dial plate 403, so that the positioning rod 408 drives the baffle 409 to move upward, so that the baffle 409 releases the limit of the positioning block 410. At this time, the plug rod 405 drives the safety tongue 407 to reset under the action of the spring. At this time, the safety tongue detection switch 10 detects the position of the safety tongue 407 and controls the electromagnetic valve 5 to release the limit of the external handle 601.

[0088] In an alternative embodiment, a rotating baffle matched with the outer handle can block the rotation of the outer handle at a specific angle position. When the control system sends a signal, the baffle can be rotated to a position allowing rotation, thereby canceling the interference.

[0089] In an alternative embodiment, a sliding slot structure can interact with a portion of the outer handle to control the rotation of the outer handle by changing the position of a sliding member in the slot. The sliding member restricts the outer handle when in a certain position and allows the outer handle to rotate when moved to another position.

[0090] In an alternative embodiment, a magnetic limit structure using an electromagnet or a permanent magnet can attract a portion of the outer handle (permanent magnet or electromagnet) to limit its rotation. When current passes through the electromagnet coil, the magnetism is enhanced to limit the outer handle; when the current is disconnected, the magnetism is weakened or disappears, and the outer handle can rotate freely.

[0091] In an alternative embodiment, a recoverable deformable structure restricts or allows the rotation of the outer handle by changing its shape. When a control system sends a signal, the deformable structure can be mechanically deformed to achieve control of the rotation of the outer handle.
