Description

Technical Field

[0001] The utility model relates to the technical field of automatic locks, in particular to an automatic lock body that can be electromechanically separated. Background Art

[0002] In the prior art, Patent CN 113202352 A discloses a full-automatic lock body, which includes structures such as a motor, a transmission structure, a clutch structure, a main lock tongue, and a lock core. When unlocking manually, when the lock core rotates, it can disconnect the motor and the clutch by pushing the clutch plate, and when the lock core continues to rotate, it can open the main lock tongue.

[0003] However, since the lock core dial must directly contact and push the clutch plate and the main lock tongue in design, the system faces relatively large friction during actual operation. Specifically, since the lock core dial has to directly contact and push the clutch plate and the main lock tongue, the friction between the lock core dial and the clutch plate and the main lock tongue is relatively large, resulting in a relatively large block when the lock core is twisted, making it difficult to unlock and easily breaking the key.

[0004] In addition, the lock body design lacks a mechanism for automatic reset of the lock core and prevention of lock core jamming. In actual use, without an effective reset mechanism, the lock core may not return to the initial position due to various reasons (such as dust accumulation, component wear, etc.), affecting the normal use of the lock. At the same time, due to the lack of a structure to prevent the lock core from jamming, the clutch plate assembly may jam the lock core dial in some cases, causing the lock core to not rotate normally, further increasing the risk of lock body failure.

[0005] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present utility model is made based on this situation. Summary of the Utility Model

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figures 1 to 5As shown, an automatic lock body that can be separated mechanically and electrically includes multiple key components to achieve complex locking and unlocking functions. The lock body mainly includes a lock housing 1, a main lock tongue component 2, an electric drive component 3, a transmission component 4, a clutch component 5 and a lock core component 6.

[0031] The lock housing 1 is the outer shell of the entire lock body, and all other components are installed inside it. The main lock tongue assembly 2 is movably connected in the lock housing 1, and is responsible for realizing the inward and outward extension of the lock tongue. The electric drive assembly 3 is also installed in the lock housing 1, and is used to drive the extension and retraction of the main lock tongue assembly 2. In order to transmit the movement of the electric drive assembly 3 to the main lock tongue assembly 2, a transmission assembly 4 is provided. The transmission assembly 4 is interconnected with the electric drive assembly 3 and the main lock tongue assembly 2 to play a transmission role.

[0032] The clutch assembly 5 plays a key role in switching between electric drive and manual drive. The clutch assembly 5 can disconnect or engage the transmission to achieve electromechanical separation or combination. The lock core assembly 6 is the core of the manual operation, including a lock core shaft 61 and a lock core fork 62 provided on the side wall of the lock core shaft 61. The lock core assembly 6 can drive the clutch assembly 5 to open and close by rotating the lock core shaft 61, and further drive the main lock tongue assembly 2 to extend and retract.

[0033] In order to achieve the above functions, a clutch plate 51 is provided between the lock core assembly 6 and the clutch assembly 5 and is slidably connected to the lock housing 1 in the up-down direction. The clutch plate 51 is movably connected to the clutch assembly 5 and is connected to the lock housing 1 through a first resetting elastic member 52 (preferably a spring), and the resetting elastic member 52 is used to pull the clutch plate 51 downward. The clutch plate 51 is provided with a first pressing portion 511 that semi-surrounds the lock core shaft 61 and is used to contact the lock core fork 62.

[0034] The transmission assembly 4 includes a plurality of transmission gears 41 arranged in sequence and meshing with each other, wherein one of the transmission gears 41 is connected to the main bolt assembly 2 via a first toggle structure, and can drive the main bolt assembly 2 to extend and retract inward and outward with the rotation of the transmission gear 41. A lock core driving tooth 63 is also rotatably connected to the lock housing 1, the lock core driving tooth 63 meshes with the transmission gear 41, and is provided with a second pressing portion 631 that semi-surrounds the lock core shaft 61.

[0035] During manual unlocking or locking, the user rotates the lock core shaft 61 forward and backward, and the lock core fork 62 presses the first pressing portion 511 of the clutch plate 51 upward, thereby disconnecting the clutch assembly 5 and achieving the effect of electromechanical separation. Then, the lock core fork 62 continues to push the second pressing portion 631 of the lock core driving tooth 63, causing the lock core driving tooth 63 to rotate, and drives the transmission gear 41 meshing with it to rotate synchronously, and finally realizes the action of the main lock tongue assembly 2.

[0036] Compared with the prior art, the innovation of this design is mainly reflected in the introduction of the lock core drive gear 63 and its role in the manual unlocking process. During manual operation, the user rotates the lock core shaft 61, and the lock core fork 62 first pushes the clutch plate 51 to achieve electro-mechanical separation, ensuring that the electric drive assembly 3 does not interfere with the manual operation. Subsequently, the lock core fork 62 pushes the lock core drive gear 63 to rotate around its axis. Since the lock core drive gear 63 meshes with the transmission gear 41, its rotation can drive the transmission gear 41 to rotate synchronously, thereby driving the telescopic movement of the main lock tongue assembly 2 to achieve the functions of unlocking or locking. The advantages of this design are mainly reflected in the following aspects:

[0037] 1) Convenience and safety of operation: By pushing the lock core drive gear 63 to rotate through the lock core fork 62, compared with directly pushing the inner and outer sliding of the main lock tongue assembly 2, the operation is easier, reducing the resistance and friction during operation and lowering the risk of jamming. This not only improves the user experience but also enhances the reliability of the lock body.

[0038] 2) Simplification and versatility of the structure: The rotational movements of the lock core drive gear 63 and the transmission gear 41 can be utilized to drive other components, such as the latch assembly and the door jamb hook assembly. This design allows these components to be directly or indirectly connected to the lock core drive gear 63 or the transmission gear 41, thereby simplifying the structure of the entire lock body, reducing the number and complexity of components, and improving the versatility of the lock body.

[0039] A lock core reset structure 7 is provided between the lock core and the clutch plate 51, which can enable the lock core fork 62 to rotate downward and reset. The function of the lock core reset structure 7 is to restore the lock core fork 62 to its initial position after the lock core operation is completed to ensure the smooth progress of the next operation.

[0040] More specifically described, the lock core reset structure 7 includes a reset plate 71 slidably connected in the lock housing 1 in the up and down direction, and a second reset elastic member 72 (preferably a spring) provided between the reset plate 71 and the lock housing 1 and used to pull the reset plate 71 downward. The function of the second reset elastic member 72 is to provide a continuous downward force so that the reset plate 71 can automatically return to its initial position after the operation is completed.

[0041] A third pressing portion 711 protruding downward is provided on the reset plate 71, and the position of the third pressing portion 711 is lower than that of the first pressing portion 511. The purpose of this design is that when the lock core fork 62 completes the pressing action on the clutch plate 51 and starts to reset, the third pressing portion 711 can timely contact and press the lock core fork 62 downward, enabling it to smoothly reset to its initial position. This design ensures that the lock core fork 62 can accurately reset after each operation, avoiding subsequent operation failures caused by improper reset, and also avoiding the problem that the lock core fork 62 may be jammed by the clutch plate 51.

[0042] More specifically, the first pressing portion 511 is a U-shaped opening, and this structural design enables the lock core fork 62 to contact it more easily and accurately during forward and reverse rotation. The lock core driving tooth 63 is a sector gear, and this sector gear design makes the driving process more stable and effective. The second pressing portion 631 is an arc-shaped opening, and the lock core fork 62 pushes up the two sides of the first pressing portion 511 and the second pressing portion 631 respectively during forward and reverse rotation.

[0043] More specifically, the lock housing 1 includes a front housing and a rear housing, and the front housing and the rear housing are both provided with arc holes 11. The design of these arc holes 11 provides necessary support and guidance for the installation and movement of the lock core drive teeth 63. The front and rear surfaces of the lock core drive teeth 63 are respectively provided with shaft ends 632 inserted into the corresponding arc holes 11, and the lock core drive teeth 63 can rotate around the lock core shaft 61. The lock core drive teeth 63 are inserted into the arc holes 11 of the front housing and the rear housing through their shaft ends 632 to form a rotation axis. The design of this rotation axis ensures that the lock core drive teeth 63 can rotate around the lock core shaft 61.

[0044] More specifically, the lock housing 1 is movably connected with a latch bolt assembly 81 that can be extended and retracted inward and outward, and the lock housing 1 is rotatably connected with a handle shaft 82. A handle is mounted on the handle shaft 82, and the user can operate the lock body by rotating the handle. The handle shaft 82 is provided with a handle driving tooth 83 that meshes with one of the transmission gears 41. This design enables the rotation of the handle shaft 82 to be transmitted to the transmission gear 41 through the handle driving tooth 83, thereby driving the internal mechanical structure of the entire lock body to perform corresponding actions.

[0045] More specifically, a second shifting structure is provided between the handle shaft 82 and the latch bolt assembly 81, and the structure can push the latch bolt assembly 81 inward and outward as the handle shaft 82 rotates. Specifically, the second shifting structure includes a first handle shifting fork 821 provided on the handle shaft 82, and an inner baffle plate 811 and an outer baffle plate 812 provided on the latch bolt assembly 81. One end of the first handle shifting fork 821 extends between the inner baffle plate 811 and the outer baffle plate 812. When the handle shaft 82 rotates, the first handle shifting fork 821 swings accordingly, pushing the latch bolt assembly 81 to slide inward and outward. This design ensures that the force of the handle operation can be accurately transmitted to the latch bolt assembly, so that it can be smoothly extended and retracted, thereby realizing the in and out movement of the lock bolt.

[0046] A third shifting structure is provided between the handle shaft 82 and the clutch plate 51, which can push the clutch plate 51 upwards to separate the clutch assembly 5 as the handle shaft 82 rotates. More specifically, the third shifting structure includes a second handle shift fork 822 provided on the handle shaft 82, and an inner stop column 512 and an outer stop column 513 provided on the clutch plate 51. The second handle shift fork 822 is provided with a shifting head 8221 extending below the inner stop column 512 and the outer stop column 513, respectively. When the handle shaft 82 rotates, the second handle shift fork 822 swings accordingly, and the inner stop column 512 or the outer stop column 513 is pulled upwards by the shifting head 8221, thereby realizing the pushing action of the clutch plate 51. This design enables the clutch plate 51 to be accurately pushed when the handle rotates, thereby realizing the effective separation of the clutch assembly 5, and ensuring that the lock body can be smoothly unlocked or locked.

[0047] More specifically, a sky hook driving tooth 91 is rotatably connected in the lock housing 1, and the sky hook driving tooth 91 is meshed with the lock core driving tooth 63 or one of the transmission gears 41. This design not only ensures the stability and reliability of the lock body, but also makes the entire lock body structure more compact and efficient. The sky hook driving tooth 91 is movably connected with an upper sky hook 92 and a lower sky hook 93 that can be raised and lowered with the rotation of the sky hook, and the upper sky hook 92 and the lower sky hook 93 are both slidably connected in the lock housing 1 along the up and down directions.

[0048] like Figure 5 As shown, the first toggle structure includes an eccentric column 411 provided on the corresponding transmission gear 41, and a drive hole 21 provided on the main lock tongue assembly 2 and into which the eccentric column 411 is inserted. The eccentric column 411 is a protruding portion connected to the transmission gear 41, and its position is not at the center of the transmission gear, but at a position offset from the center. When the transmission gear 41 rotates, the eccentric column 411 moves along a circular trajectory due to its eccentric position. This motion trajectory is transmitted to the main lock tongue assembly 2 through the eccentric column 411 inserted in the drive hole 21, so that the main lock tongue assembly 2 can perform a smooth linear movement. This design ensures that the opening and closing action of the lock tongue can be performed accurately and smoothly, and provides an efficient locking and unlocking function.
