Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to an electronic fully automatic lock body. Background Art

[0002] The lock body includes a lock tongue with an inclined surface. The lock tongue with a single inclined surface is directional. Therefore, if it needs to be installed in the opposite direction during actual installation, it is usually necessary to disassemble the lock body, replace the lock tongue or rotate the lock tongue 180°, which makes the installation more cumbersome. In addition, the existing lock body is manually unlocked, and the user usually needs to use a key or other tools to operate it personally. This will cause inconvenience if both hands are occupied or at inconvenient times (such as at night, bad weather, etc.). The manually unlocked lock body cannot provide intelligent functions such as integration into smart home systems, support remote control and monitoring, and even automatically perform certain operations according to user habits. Although traditional mechanical locks also have their own unique security mechanisms, with the development of technology, some advanced unlocking technologies (such as key bumping, lock picking, etc.) are constantly emerging, and the security is insufficient. For the elderly and children, it may be difficult to use traditional manual locks, especially those with complex designs or locks that require greater force to open.

[0003] For example, the patent publication number CN117145313A - A two-way flip locking mechanism and lock body, discloses a two-way flip locking mechanism and a lock body, wherein the two-way flip locking mechanism includes: a lock shell; a bevel tongue plate, slidably arranged on the lock shell; a bevel tongue, rotatably mounted on the bevel tongue plate, the bevel tongue having a first working surface and a second working surface, the first working surface and the second working surface being inclined and respectively located on both sides of the bevel tongue, the bevel tongue also having a first slide groove and a second slide groove, the first slide groove being inclined with the second working surface, and the second slide groove being inclined with the first working surface; a bevel tongue plate reset elastic member; a locking block, which is used to slide with the first slide groove or the second slide groove. The present application uses a rotatable bevel tongue, combined with a locking block and the first working surface, the second working surface, the first slide groove and the second slide groove of the bevel tongue, to realize the convenient switching of the two installation directions without removing or replacing the bevel tongue. Summary of the invention

[0004] Technical problem to be solved by the invention

[0005] The technical problem to be solved by the present invention is to provide an electronic fully automatic lock body with a built-in reduction motor and a detection switch, diverse functions, a compact lock body, low overall power consumption, fast speed and strong unlocking force, and through a rotatable flip tongue, it is possible to conveniently switch between two installation directions without removing or replacing the oblique tongue.

[0006] Technical Solution

[0007] To solve the above problems, the technical solution provided by the present invention is:

[0008] An electronic fully automatic lock body, comprising

[0009] The driving structure comprises a reduction motor, a motor gear and a convex gear which are connected in a transmission manner. The convex gear is embedded with a square tongue shift block and a square steel shift piece. The inner sides of the convex gear and the square tongue shift block are respectively provided with an inner ring convex first and an inner ring convex second which are abutted and matched. The gear side surface of the convex gear is provided with a convex point.

[0010] The flip tongue structure comprises a flip tongue provided with a bidirectional inclined surface and a fork slide groove, the flip tongue is hinged with a retractable flip plate, the flip plate is equipped with a micro switch, the fork slide groove is equipped with a locking block, the locking block is a lever structure and is driven by the convex point to engage and lock with the slide groove of the fork slide groove;

[0011] A trigger tongue structure, including a retractable trigger tongue and a micro switch triggered after retraction, wherein the micro switch is connected to a controller;

[0012] The main lock tongue structure comprises a retractable main lock tongue, the main lock tongue is provided with a main lock driving groove, the groove walls at both ends of the main lock driving groove are respectively in transmission contact with the extension part of the square tongue block corresponding to the retracted state, the convex gear is coaxially sleeved with a square steel paddle, the square steel paddle cooperates with the unlocking paddle and the locking paddle to control the square tongue block, the square tongue block pushes the main lock tongue to move, and the main lock tongue, the locking paddle and the unlocking paddle are stacked.

[0013] The lock body has a built-in high-performance reduction motor and a detection switch. Together with the digital communication signal, it controls the operation of the reduction motor inside the lock, driving the gear transmission to retract or extend the lock tongue, thereby achieving the purpose of unlocking or locking.

[0014] The flip tongue can be locked by a locking block after being flipped in different directions. Without removing the panel or replacing the flip tongue, the automatic switching of the two installation directions of the lock body can be realized more conveniently.

[0015] The convex gear is embedded with the square tongue block and the square steel paddle, and the main lock tongue, the lock head paddle and the unlocking paddle are stacked. Under the condition of perfect lock body functions, the lock body space is greatly saved, the lock body volume is reduced, and it is helpful to manufacture a more compact and exquisite lock body, and the material cost can be reduced to a certain extent. The inner side of the convex gear and the square tongue paddle is respectively provided with the inner ring convex one and the inner ring convex two for abutment and matching. The main lock tongue is provided with a main lock driving groove. The groove walls at both ends of the main lock driving groove are respectively abutted with the extension part of the square tongue paddle in the corresponding telescopic state, which optimizes the force transmission path and improves the working efficiency of the entire driving structure. This means that the lock body can achieve fast and stable locking and unlocking operations while consuming less energy. The compact design reduces the gap between moving parts and reduces the risk of loosening due to vibration or long-term use, thereby enhancing the stability and reliability of the lock body. The smaller lock body size enables it to adapt to more types of door types and installation environments, increasing the scope of application of the product.

[0016] The square steel paddle is used for mechanical unlocking. Square steel can be used to pry the square steel paddle block to unlock the main lock tongue through the transmission mechanism, avoiding the risk of not being able to open the door in the event of electronic component failure.

[0017] Function of the trigger tongue: the locking block locks and unlocks the flip tongue. Method 1: when the trigger tongue is retracted, the motor drives the gear, and the gear pushes the locking block to lock and unlock the flip tongue under the power transmission; Method 2: when the trigger tongue is extended, the locking block is unlocked through the structural transmission of the trigger tongue bracket, and the trigger tongue is retracted and locked by the locking block.

[0018] Optionally, a bevel gear is provided at the output end of the reduction motor, and the end face of the motor gear cooperates with the bevel gear.

[0019] By using bevel gears, the direction of force can be changed in a compact space, which makes the entire drive structure more compact and helps to further reduce the overall size of the lock body. Bevel gears can effectively convert the rotational power of the reduction motor into a power form suitable for the internal mechanical structure of the lock body (such as convex gears, square tongue blocks, etc.), ensuring efficient transmission of force, thereby improving the operating efficiency of the entire system. Bevel gears usually have good wear resistance and strength, and can maintain stable performance during long-term use, reducing the problem of functional degradation caused by wear and enhancing the reliability and durability of the lock body.

[0020] Optionally, a micro-trigger protrusion extends from the rotating part of the square tongue block, and a micro-switch is provided at the same plane height as the square tongue block to cooperate with the micro-trigger protrusion to generate a signal.

[0021] When the square bolt moves, the micro-trigger protrusion touches the micro switch, generating an electrical signal. This signal can be used to accurately determine the position status of the square bolt (such as fully extended or retracted). By monitoring the status of the square bolt, the system can automatically perform corresponding actions, such as stopping the motor when it detects that the door is properly locked, or adjusting the drive force and speed according to the actual position during the unlocking process, thereby improving the intelligence level of the entire lock body. If any problems occur, such as the lock tongue is stuck and cannot work properly, the system can quickly locate the problem based on the information provided by the micro switch, simplifying the maintenance and troubleshooting process. Based on the accurate perception of the position of the square bolt, the system can more efficiently manage the duty cycle of the reduction motor, avoid unnecessary energy consumption, and help extend the battery life (especially important for battery-powered locks).

[0022] Optionally, the motor gear is connected to a signal gear and a signal controller.

[0023] Signal Gear: Through the connection with the motor gear, the signal gear can accurately track the rotation of the motor gear. This allows the system to know exactly when the deadbolt is fully extended or retracted, thus ensuring the accuracy of locking and unlocking operations.

[0024] Signal controller: The signal controller receives information from the signal gear and makes corresponding control decisions accordingly. For example, when it detects that the lock tongue has been fully retracted, the signal controller can command the reduction motor to stop running to avoid unnecessary energy consumption or mechanical wear.

[0025] Optionally, the unlocking paddle is a hinged lever structure, one end of the unlocking paddle is overlapped with the square steel paddle, and the other end of the unlocking paddle is overlapped with the locking protrusion of the locking paddle.

[0026] The articulated lever structure can effectively convert and amplify the applied force, so that the unlocking action can be completed smoothly even with a small force input. It improves the response sensitivity and reliability of the system, helps to optimize the entire unlocking process, and ensures that each operation can be performed smoothly and accurately. In the event of a failure of the electronic control system or insufficient power, the user can still manually unlock the door lock mechanically, increasing the safety and availability of the system. This provides users with an important backup unlocking method, which is particularly important in emergency situations.

[0027] Optionally, the locking block is provided with a protrusion, and the protrusion is cooperated with an unlocking piece, the unlocking piece is hinged and has two ends of a lever structure, the protrusion is limited at the middle section of the unlocking piece and drives the unlocking piece to rotate, one end of the unlocking piece overlaps the flip plate, and the other end of the unlocking piece overlaps the second lock protrusion of the lock paddle.

[0028] The convex point on the locking block is located in the middle section of the unlocking piece to limit the position and drive the unlocking piece to rotate. This means that when the locking block moves, the convex point on it will touch and push the unlocking piece, causing the unlocking piece to rotate around the hinge point. One end of the unlocking piece is in contact with the flip plate. When the unlocking piece rotates due to the action of the convex point, this action will be transmitted to the flip plate, causing the flip plate to move or change state. The other end of the unlocking piece is connected to the lock head protrusion on the lock head paddle. In this way, the action of the unlocking piece can not only control the state of the flip plate, but also directly affect the position of the lock head paddle, and then affect the state of the main lock tongue. The use of a lever structure can effectively convert the direction and magnitude of the force, so that a smaller input force (such as the force of the convex point on the unlocking piece) can produce a larger output effect (such as the movement of the flip plate and the lock head paddle). This improves the efficiency and response sensitivity of the system. At the same time, it also increases the redundancy of the system

[0029] Optionally, a bent section is provided in the middle section of the unlocking piece, and the bent section is overlapped with the protrusion in a crank slider structure.

[0030] The bent section in the middle of the unlocking piece enables the unlocking piece to form an inflection point at a specific position, so that the movement trajectory of the unlocking piece can be more accurately controlled.

[0031] Optionally, the trigger tongue is a bidirectional inclined surface structure.

[0032] The bidirectional slope structure means that the trigger tongue can receive and respond to forces from two directions. Whether the door is closed from the inside or outside, or pushed or pulled from any direction, the trigger tongue can effectively trigger the corresponding micro switch, thus ensuring a stable response of the system.

[0033] As an option, the reduction motor is arranged close to the transmission structure.

[0034] Placing the reduction motor close to the transmission structure helps reduce the size of the entire lock body, making it more compact. By placing the reduction motor directly close to the transmission structure, the power transmission path can be shortened, reducing energy loss caused by long-distance transmission and improving overall efficiency. A shorter power transmission path means a faster response time, which can increase the speed at which the lock body receives a command and completes the locking or unlocking operation.

[0035] Optionally, the unlocking paddle is hinged by a main lock pin shaft, the main lock tongue is provided with a straight waist hole, the lock head paddle is provided with an arc waist hole, and the main lock pin shaft passes through the straight waist hole and the arc waist hole.

[0036] The straight-waist hole design allows the main lock pin to slide inside it. This provides a flexible way for the main lock tongue to move in a straight direction while maintaining a mechanical connection with the unlocking paddle and the lock paddle. This ensures that the main lock tongue can be retracted and extended smoothly and accurately. The curved-waist hole allows for greater angular variation than the straight-waist hole. This means that when the lock paddle rotates, the main lock pin can move in a rotating manner by accommodating the unlocking paddle through the curved-waist hole. The unlocking paddle is hinged at the lower end with a torsion spring pin, and the unlocking paddle can rotate around the torsion spring pin.

[0037] Beneficial Effects

[0038] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0039] The technical solution provided by the present invention improves the intelligence level of the lock, and also significantly improves its practicality and safety. It also has the advantages of a small lock body, low overall power consumption, high speed, and strong unlocking force. BRIEF DESCRIPTION OF THE DRAWINGS
