Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example

[0038] See Figures 1 to 5 As shown, a gear-driven built-in motor electric lock body includes a base 1, a cover plate 2, and a front panel 3. An electric lock body 4 is provided between the base and the cover plate. In this embodiment, the base, cover plate, and front panel are all conventional structures of the prior art, and are simply applied, so they are not described in detail. The base and cover plate are fixed with screws.

[0039] In this embodiment, the electric lock body includes a motor 41, a motor gearbox 42, a transmission gear 43, a linkage plate 44, a latch body 45, and a latch actuating component 46; a magnetic sensor 27 is provided on the latch body. Its magnetic sensor mainly works in conjunction with the magnet on the latch box on the door frame to sense whether the door is closed. Its motor is connected to an external power source via wires for power supply, which is conventional in existing technology. The latch body is also a conventional structure in existing technology, realizing the unlocking or locking operation. During assembly, the motor and the motor gearbox are connected and fixed to the base. The transmission gear is rotatably connected to the base via shaft 5 and meshes with the output gear of the motor gearbox. Furthermore, the middle part of the latch actuating member is rotatably connected to the base via shaft 6, and one end of the latch actuating member is connected to the latch body. In this embodiment, the latch actuating member is V-shaped and the corner is connected to the shaft. When rotating, the other end will drive the latch body to retract. Furthermore, the linkage plate is connected between the transmission gear and the latch actuating member. In use, the transmission gear rotates, driving the linkage plate to translate, and the linkage plate drives the latch actuating member to rotate and drives the latch body to retract through the end of the latch actuating member. The above structure improves transmission efficiency, reduces wear on structural components, ensures accurate locking and unlocking positions, enhances transmission smoothness and reliability, and reduces the likelihood of slippage or errors. Furthermore, the transmission gears, in conjunction with the output gears of the motor gearbox, improve the space utilization efficiency of the lock body, enabling locking and unlocking operations to be completed in extremely narrow spaces, thus reducing the overall structural volume.

[0040] In this embodiment, a protruding post 7 is provided on the top surface of the transmission gear near its edge; and a straight guide groove 8 is provided in the middle of the linkage plate, with an n-shaped locking groove 9 at one end and an oblong hole 10 at the other end; the straight guide groove is oriented from the transmission gear to the oblique tongue, ensuring that the linkage plate can move between the transmission gear and the oblique tongue; and a guide post 11 is provided on the base, with the linkage plate positioned on the base, and the guide post can be translatably positioned within the straight guide groove; through the above structure, the translational position accuracy of the linkage plate can be ensured, preventing tilting or displacement; and the n-shaped locking groove is connected to the protruding post, and the oblong hole is connected to the oblique tongue actuating component via a pin 26. The width of the n-shaped locking groove is greater than the diameter of the protruding post, thus providing a certain transmission space.

[0041] In this embodiment, a slanted tongue main board 12 is provided on the base, and a reset torsion spring 13 is provided on the slanted tongue main board; one end of the reset torsion spring abuts against the slanted tongue main board and the other end abuts against the tail of the slanted tongue body, for resetting the slanted tongue body to extend out of the front panel. Through the above structure, it can be ensured that the slanted tongue body can be reset to achieve the extension operation.

[0042] Furthermore, in this embodiment, the base is also provided with a high-pressure plate 14, a square locking tongue 15, and a high-pressure plate guide plate 16. During assembly, the square locking tongue is fixed to the high-pressure plate, and the high-pressure plate guide plate is located on the top surface of the horizontal plate of the high-pressure plate. A strip-shaped groove 17 is provided on the top surface of the horizontal plate of the high-pressure plate and on the high-pressure plate guide plate. The main shaft of the transmission gear passes through the strip-shaped groove. In this embodiment, the strip-shaped groove mainly ensures that the square locking tongue can effectively achieve telescopic operation, and the high-pressure plate guide plate is mainly used for positioning and connecting the high-pressure plate, ensuring the stability and effectiveness of the connection.

[0043] In this embodiment, a support plate 18 is provided on the top surface of the directional plate of the high-strength plate, and a limiting block 19 is provided on the support plate; a recessed area 20 and an arc-shaped limiting groove 21 are provided on the transmission gear, the arc-shaped limiting groove being located within the recessed area, and a torsion spring body 22 is provided on the top surface of the transmission gear; during assembly, the transmission gear is attached to the top surface of the support plate, and the limiting block is movably disposed within the arc-shaped limiting groove; the torsion spring body is sleeved on the shaft of the transmission gear, and its two ends respectively abut against the inner wall of the recessed area and the limiting block. Through the above structure, not only can the rotation angle of the transmission gear be limited to prevent excessive rotation, but it also facilitates the rapid reset of the transmission gear.

[0044] In this embodiment, a circuit board and a Hall sensor 23 connected to the circuit board are fixed on the base. The Hall sensor is a conventional structure in the prior art, simply applied, primarily used to sense whether the lock body is fully closed. When the lock body is detected to be fully closed, the locking drive is initiated. The circuit board is also a conventional structure in the prior art, simply applied, primarily used for driving and controlling the motor.

[0045] In another embodiment, a mechanical lock 24 is provided on the base and cover plate, and a semi-circular gear 25 connected to the mechanical lock is provided on the base. The semi-circular gear meshes with or disengages from the transmission gear. With this structure, the mechanical lock can drive the semi-circular gear to rotate, thereby driving the transmission gear to rotate, realizing mechanical unlocking operation and improving the effectiveness and stability of the operation. In practical applications, the mechanical lock also has a limit block with an arc-shaped guide groove. An arc-shaped guide block is movable within the arc-shaped guide groove on the top surface of the semi-circular gear. The length of the arc-shaped guide block is less than the width of the arc-shaped guide groove. The semi-circular gear is limited by both ends of the arc-shaped guide groove when rotating.

[0046] This utility model has positive effects: its structure is reasonably designed, and its electric lock body includes a motor, a motor gearbox, a transmission gear, a linkage plate, a latch body, and a latch actuating component. The linkage plate is connected between the transmission gear and the latch actuating component. The rotation of the transmission gear is converted into the translation of the linkage plate, which is then converted into the rotational force of the latch actuating component, thereby realizing the retraction operation of the latch body. This increases the transmission efficiency, reduces the wear of structural components, ensures the accuracy of the unlocking position, and improves the stability of use. At the same time, it makes high space utilization of the lock body, enabling the opening and closing of the electric lock body in a very narrow space. This helps to reduce the overall size of the lock body and can meet the installation and use needs of different locations.

[0047] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
