Description

Technical Field

[0001] This invention relates to the field of lock body technology, specifically to an electric lock body. Background Technology

[0002] The most traditional door locks generally use a manual key mechanical opening method. Although it is relatively reliable, it is difficult to achieve automatic control and is not as easy to change the opening and closing conditions as electric door locks. Later, the industry began to use electrically controlled door locks, which can identify the door through infrared, fingerprint, card, password, etc., and control the motor to rotate through logic circuits to drive the bolt to open and close. To avoid the door being unable to open or close due to electric control failure, many electric door locks still retain the mechanism of key opening and closing.

[0003] In related technologies, electric door locks are generally of two types: one type uses a mechanical lock body with a rear panel motor drive structure, and the other type uses an internal motor drive structure. However, the former has poor structural fit accuracy, serious efficiency loss, and unstable output torque; the latter has low power conversion efficiency or small output torque, and its application effect is also poor. Summary of the Invention

[0004] The purpose of this invention is to provide an electric lock body that uses a clutch drive mechanism driven by a geared motor assembly inside the lock body. The clutch drive mechanism engages and disengages to achieve coordinated operation with the main bolt assembly, the inclined bolt assembly, and the triangular bolt assembly. This provides convenient electric unlocking and locking, ultra-low energy consumption, the ability to unlock under heavy loads, and a simple structure, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An electric lock body includes a lock shell, a lock body panel, a main bolt assembly, a latch bolt assembly, a lock cylinder assembly, and a triangular bolt assembly disposed within the lock body. The main bolt assembly, the latch bolt assembly, and the triangular bolt assembly all pass through the lock body panel, and a clutch drive mechanism is provided between the main bolt assembly and the latch bolt assembly.

[0007] The clutch drive mechanism includes a clutch column, a first linkage plate, an unlocking dial, and a gear plate that are sequentially sleeved on the clutch column from bottom to top and rotate synchronously with each other. The first linkage plate is provided with a motor drive gear that cooperates with a reduction motor assembly to achieve linkage. The unlocking dial is provided with a first hole.

[0008] The main bolt assembly includes, from bottom to top, a lock cylinder deflector, a main bolt, and a main bolt deflector arm. The main bolt and the main bolt deflector arm are linked together. The main bolt deflector arm is linked with a gear plate through gears. The lock cylinder deflector has a first protrusion connected to the first hole.

[0009] The lock cylinder assembly and the lock cylinder lever are interconnected.

[0010] The first linkage plate has a first column that drives the unlocking dial to rotate, and the unlocking dial has a second protrusion that drives the gear plate to rotate.

[0011] The clutch drive mechanism has a locking plate on its side, and the unlocking dial has an arc protrusion that cooperates with the locking plate and drives the locking plate to move.

[0012] The tongue assembly includes a support plate, a tongue seat, and a tongue that is rotatably connected to the tongue seat via a rotating shaft.

[0013] The oblique tongue has a first positioning block, a second positioning block and a third positioning block at one end. A left upper locking groove for locking the locking plate is formed between the first positioning block and the second positioning block, and a right upper locking groove for locking the locking plate is formed between the second positioning block and the third positioning block.

[0014] The tongue seat includes a vertical section and a horizontal section. The horizontal section has a sliding groove, and a positioning post is installed in the sliding groove to realize the vertical movement of the tongue assembly. A spring is installed between the vertical section and the support plate. The support plate has a slot for installing the horizontal section.

[0015] The locking plate is equipped with a torsion spring that facilitates locking or unlocking the locking plate with the upper locking groove. One end of the torsion spring is connected to the locking plate, and the other end is connected to the support plate.

[0016] The triangular tongue assembly includes a triangular tongue, a triangular tongue seat with an elastic element sleeved on the outside, and a boss disposed on the triangular tongue seat. The boss is linked with a second linkage piece, and the other end of the second linkage piece is linked with a locking piece.

[0017] Motor unlocking: The gear of the reduction motor assembly rotates counterclockwise, driving the motor transmission gear on the first linkage plate to rotate clockwise. This drives the gear plate and the unlocking dial to rotate clockwise via the boss. The gear plate meshes with the main lock tongue lever arm, causing the main lock tongue lever arm to rotate counterclockwise and pull back the main lock tongue. The unlocking dial wheel pushes open the locking plate through the arc protrusion, separating the locking plate from the inclined tongue, allowing the inclined tongue to be freely flipped and unlocked.

[0018] Lock cylinder paddle unlocking: The lock cylinder paddle is connected to the unlocking paddle shaft hole. The external lock cylinder mechanism drives the lock cylinder paddle, which pushes the unlocking paddle and gear plate to rotate clockwise. The gear plate meshes with the main lock tongue arm, causing the main lock tongue arm to rotate counterclockwise and pull back the main lock tongue. The unlocking paddle pushes open the locking plate through the arc protrusion, and the locking plate separates from the latch, allowing the latch to be freely flipped and unlocked.

[0019] Door closing and locking: When the door closing triangular tongue is pressed in, the protrusion of the triangular tongue separates from the second linkage plate, the locking plate is opened longitudinally, and under the action of the spring, the locking plate engages in the slide groove of the oblique tongue, restricting the oblique tongue from turning over and realizing door locking; at the same time, the gear of the reduction motor assembly rotates clockwise, driving the motor transmission gear and gear plate to rotate counterclockwise, and the gear plate drives the main lock tongue lever to rotate clockwise, and the main lock tongue lever pushes the main lock tongue to lock.

[0020] In the unlocked state, the locking plate separates from the upper locking groove of the latch, and the latch returns to the middle state under the action of the spring. When the closing force causes the latch to flip to the left, the locking plate engages with the left upper locking groove of the latch under the action of the spring, realizing left-side locking. When the closing force causes the latch to flip to the right, the locking plate engages with the right upper locking groove of the latch under the action of the spring, realizing right-side locking. The clutch drive mechanism pushes the locking plate away from the latch, thus unlocking the door.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The structure of this invention utilizes a clutch drive mechanism driven by a geared motor assembly within the lock body. The clutch drive mechanism's engagement and disengagement enable linkage with the main bolt assembly. A locking plate located beside the clutch drive mechanism locks the door when it engages the latch bolt and unlocks it when it disengages. The locking plate is also connected to the triangular bolt assembly for linkage. The main bolt is connected to the lock cylinder lever, synchronously driving the clutch drive mechanism and the latch bolt assembly. This invention features a reasonable structure, convenient electric unlocking and locking, ultra-low energy consumption, the ability to unlock under heavy loads, a simple structure, ease of use, reliable and stable operation, minimal wear on the clutch mechanism within the lock body, and low installation requirements for the lock body, facilitating daily installation and use.
