Description

Technical Field

[0001] The utility model relates to the technical field of automatic locks, in particular to an automatic lock body clutch structure. Background Art

[0002] In existing fully automatic lock bodies, the design of electromechanical separation is usually adopted. For example, patent application CN113202352 A discloses a fully automatic lock body, which realizes electromechanical separation by rotating the lock core to drive the clutch plate to rise and fall. Specifically, the clutch plate of the lock body is provided with an arc-shaped opening at the lower end, and the lock core is provided with a lock core shift fork. When the lock core rotates, the lock core shift fork will press the arc-shaped opening to push the clutch plate to move upward.

[0003] However, this structure has some problems, one of which is that the lock cylinder fork is easily stuck by the clutch plate. Since the clutch plate is heavy, when the lock cylinder fork enters the arc-shaped opening, a large force is required to lift the clutch plate. At the same time, the friction between the lock cylinder fork and the arc-shaped opening will also increase, which increases the possibility of the lock cylinder fork being stuck due to excessive friction.

[0004] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

[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] exist Figures 1 to 5 The automatic lock body clutch structure shown includes a lock housing 1, a main lock tongue assembly 2, a drive wheel 3, a lock core assembly 4 and an electric drive assembly 5. In order to solve the problem that the lock core fork 42 is stuck, the utility model introduces an innovative design of an auxiliary plate 74.

[0031] A main lock tongue assembly 2 that can be extended left and right is slidably connected inside the lock housing 1, and a driving wheel 3 for driving the main lock tongue to extend left and right is rotatably connected. Figure 3 As shown, the driving wheel 3 is usually provided with a first eccentric column 31, and the main lock tongue is provided with a first guide hole 21 for inserting the first eccentric column 31. When the driving wheel 3 rotates, the main lock tongue will slide left and right to extend or retract into the lock housing 1.

[0032] The lock housing 1 is also provided with a lock core assembly 4 and an electric drive assembly 5 for driving the driving wheel 3 to rotate, and a first transmission assembly 6 is provided between the electric drive assembly 5 and the driving wheel 3 to achieve transmission. The electric drive assembly 5 generally includes a forward and reverse motor, and the first transmission assembly 6 generally consists of a gear transmission structure composed of gears meshing with each other.

[0033] The clutch assembly 7 is a key component of the utility model, including a clutch 71 (the clutch is a conventional structure, see CN113202352A, no further description is given here), a clutch plate 72 and an elastic reset member 73. The clutch 71 is arranged between the output shaft of the electric drive assembly 5 and the first transmission assembly 6, and the clutch plate 72 is slidably connected in the lock housing 1 along the up and down directions, and is used to drive the opening and closing of the clutch 71. The elastic reset member 73 (preferably a spring) is designed to elastically press the clutch plate 72 downward. The lock core assembly 4 includes a lock core shaft 41 located below the clutch plate 72 and a lock core fork 42 located on the lock core shaft 41. In addition, auxiliary plates 74 are respectively provided on the left and right sides of the clutch plate 72, and these auxiliary plates 74 extend from the lower end of the clutch plate 72 and extend to the left and right sides of the lock core shaft 41.

[0034] The important innovation of the present utility model is the introduction of an auxiliary plate 74 to prevent the lock cylinder fork 42 from being stuck. Specifically, when the key is inserted and the lock cylinder shaft 41 is rotated, the lock cylinder fork 42 will respectively press the auxiliary plate 74 upward, indirectly pushing the clutch plate 72 to move upward, thereby disconnecting the clutch. When the lock cylinder fork 42 presses the auxiliary plate 74, the lower end of the auxiliary plate 74 contacts the side of the lock cylinder fork 42, but not the end face of the lock cylinder fork 42, which avoids the problem of the lock cylinder fork 42 being stuck. Through this innovative design, the stable operation and reliability of the lock body clutch structure are achieved, providing a better user experience.

[0035] Furthermore, the auxiliary plates 74 are all in the shape of long strips, and the lower ends of the two auxiliary plates 74 and the lower end edges of the clutch plate 72 form a half-mouth shape that half-encloses the lock core shaft 41. When the lock core fork 42 presses the auxiliary plates 74, only the lower ends of the auxiliary plates 74 will contact the side of the lock core fork 42. By adopting this semi-enclosed auxiliary plate 74 design, the risk of the lock core fork 42 being stuck by the clutch plate 72 is effectively reduced. The shape and position of the auxiliary plates 74 ensure that the lock core fork 42 can apply force at the correct position, so that the clutch plate 72 can be pushed smoothly. This design improvement improves the reliability and stability of the automatic lock body and ensures the normal operation of the lock core fork 42.

[0036] In a more preferred solution, the auxiliary plate 74 is designed to slide up and down on the clutch plate 72. This movable connection further improves the flexibility and reliability of the automatic lock body. The ability of the auxiliary plate 74 to slide up and down allows it to push the clutch plate 72 to perform a clutch operation, and also to push the lock cylinder fork 42 to reset when necessary, thereby enhancing the coordination of the entire lock body structure.

[0037] Specifically, a first through hole 741 is provided at the upper portion of the auxiliary plate 74, a first strip hole 721 is provided at a corresponding position of the clutch plate 72 along the up-down direction, and a first pin 75 is provided between the first through hole 741 and the first strip hole 721; a second strip hole 742 is provided at the lower portion of the auxiliary plate 74 along the up-down direction, a second through hole 722 is provided at a corresponding position of the clutch plate 72, and a second pin 76 is provided between the second strip hole 742 and the second through hole 722.

[0038] More specifically, the interaction between the clutch plate 72 and the drive wheel 3 is realized through the second transmission assembly 8, which brings higher operational flexibility and efficiency to the entire lock body clutch structure. The up and down movement of the clutch plate 72 can not only drive the clutch 71 to engage and disengage, but also directly drive the drive wheel 3 to rotate, thereby realizing the locking and unlocking operations of the lock body.

[0039] The key to the second transmission assembly 8 is the handle shaft 81, which is rotatably connected in the lock housing 1 and connected to the drive wheel 3 through a gear meshing transmission structure (a transmission system composed of a plurality of gear pairs, bevel gear pairs and other gear parts). This design allows the rotation of the handle shaft 81 to directly cause the drive wheel 3 to rotate, thereby achieving the purpose of controlling the extension and retraction of the main lock tongue assembly 2. More importantly, by introducing the first toggle structure 82, this system can also convert the up and down movement of the auxiliary plate 74 into the rotational movement of the handle shaft 81, and convert the rotational movement of the handle shaft 81 into the up and down movement of the auxiliary plate 74, thereby realizing the mutual conversion of movement forms and greatly enhancing the interactivity and efficiency of the system.

[0040] Specifically, the first toggle structure 82 realizes its function by using two toggle heads 811 arranged on the side wall of the handle shaft 81. Each toggle head 811 is connected with a corresponding first pin 75, and the first pin 75 is fixed on the corresponding auxiliary plate 74. This design allows the toggle head 811 to interact with the auxiliary plate 74. During the process of unlocking the lock cylinder by rotating the key, when the auxiliary plate 74 and the clutch plate 72 move up and down, the toggle head 811 is pushed by the guiding effect of the first pin 75, thereby causing the rotation of the handle shaft 81. Conversely, during the process of rotating the handle shaft 81 to unlock, the rotation of the handle shaft 81 can also push the first pin 75 through the toggle head 811, thereby driving the auxiliary plate 74 to move up and down, thereby realizing the up and down movement of the clutch plate 72.

[0041] This innovative design effectively combines the direct physical movement of the auxiliary plate 74 with the rotational movement of the drive wheel 3 inside the lock body, which not only improves the operational flexibility and response speed of the automatic lock body clutch structure, but also improves the reliability and durability of the entire system. Through this mechanical interaction design, users can control the locking and unlocking of the lock body more conveniently and safely.

[0042] More specifically, the lock housing 1 is slidably connected with an oblique bolt assembly 83 that can be extended left and right, and the handle shaft 81 is provided with an oblique bolt shifting plate 84 for directly shifting the oblique bolt assembly 83 left and right. Figure 3 The oblique bolt shifting plate 84 is provided with an oblique bolt shifting head 841 extending toward the oblique bolt, which can shift the oblique bolt left and right. In this way, the oblique bolt assembly 83 can be directly operated when the handle shaft 81 is rotated.

[0043] More specifically, the oblique bolt assembly 83 can also be operated by the driving wheel 3 (the driving wheel 3 can be driven to rotate by the lock cylinder and the motor), that is, a third transmission assembly 85 is provided between the driving wheel 3 and the oblique bolt plate 84.

[0044] like Figure 3As shown, the third transmission assembly 85 includes a transmission plate 851 slidably connected to the lock housing 1 in the up-down direction, a pressing angle 842 provided on the oblique tongue plate 84 and capable of pressing the upper end of the transmission plate 851 downward, a second guide hole 8511 provided on the transmission plate 851, and a second eccentric column 852 provided on the driving wheel 3 and inserted into the second guide hole 8511.

[0045] More specifically, a top and bottom hook assembly 9 that can slide in the up and down direction is slidably connected in the lock housing 1, and a second toggle structure 91 for converting the rotational motion of the driving wheel 3 into the up and down sliding motion of the top and bottom hook assembly 9 is provided between the driving wheel 3 and the top and bottom hook assembly 9. Figure 3 In the structure shown, the second toggle structure 91 is composed of a third eccentric column 911 located on the driving wheel 3 and a third guide hole 912 on the sky hook assembly 9. The third eccentric column 911 is designed to be inserted into the third guide hole 912, so that when the driving wheel 3 rotates, the lifting and lowering movement of the third eccentric column 911 due to its eccentric design will be transmitted to the sky hook assembly 9, prompting it to move up and down along the preset sliding path in the lock housing 1. This design not only ensures that the sky hook assembly 9 can move up and down accurately with the rotation of the driving wheel 3, but also makes the overall structure of the lock body more compact and efficient.
