[0024] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In this embodiment, a lock body structure is disclosed. Figure 1 The internal structure of the lock body structure in the initial state, that is, locked and not locked, is shown. Figure 2 The internal structure of the lock body structure when it is just locked is shown. Figure 3 The internal structure of the lock body structure when it is in the reverse locked state and the peach assembly is restored to the initial position is shown. Figure 4 The figure shows the exploded structure of the peach assembly in the lock body structure. Figure 5a and Figure 5b The exploded structure of the driving assembly in the lock body structure is shown from two different perspectives.

[0026] Please refer to Figures 1 to 5bThe lock body structure in this embodiment includes a shell 2 and a lock tongue 1, a drive assembly 3, a peach assembly 4 and a first spring 51 arranged therein. Among them, a lock tongue hole is provided on the side of the shell 2, and the middle part of the lock tongue 1 is rotatably arranged in the shell 2. The outer end of the lock tongue 1 can be rotated to the outside of the shell 2 through the lock tongue hole under the action of a magnet. In other words, the lock tongue 1 is a magnetic lock tongue. When the lock body structure is applied to the door, a magnetic buckle box needs to be installed on the door frame at the same time, and the lock tongue 1 is sucked out by the magnet in the magnetic buckle box, so that automatic locking is achieved when the door is closed. This locking process does not require the coordination and linkage of other structures inside the lock body, so it can reduce the noise when locking the door to a certain extent. In addition, a buffer pad made of a flexible material can be set on the outer end of the lock tongue 1, which can further reduce the noise when colliding with the buckle box.

[0027] In this embodiment, the locking tongue 1 is locked and rotated into the housing 2 by the driving assembly 3, that is, the reverse locking and unlocking are realized. Specifically, the driving assembly 3 includes a first paddle 31 and a second paddle 32 coaxially rotatably arranged in the housing 2. The outer periphery of the first paddle 31 is provided with a first lever 313 that can abut against the inner side of the inner end of the locking tongue 1. When the outer end of the locking tongue 1 rotates to the outside of the housing 2, its inner end will move closer to the driving assembly 3. At this time, the locking tongue 1 is locked and unlocked. Figure 1 When the first paddle 31 is rotated counterclockwise, the first lever 313 will abut against the inner side of the inner end of the lock tongue 1. Continuously rotating the first paddle 31 can drive the lock tongue 1 to rotate clockwise, so that its outer end is retracted into the housing 2, thereby achieving unlocking.

[0028] In this embodiment, the rotation of the driving assembly 3 is realized by the peach assembly 4, and the peach assembly 4 is connected to the handle when in use, so that the user can operate the lock body structure. Specifically, the first paddle 31 is composed of a first sheet 311 and a second sheet 312 in this embodiment, and teeth meshing with the peach assembly 4 are provided on the outer periphery of the first sheet 311, so that it can rotate simultaneously with the peach assembly 4. The first convex block 314 and the second groove 315 that are mutually embedded are provided on the side surfaces of the first sheet 311 and the second sheet 312, so that the first sheet 311 and the second sheet 312 can rotate synchronously. The first lever 313 is provided on the outer periphery of the second sheet 312. In other embodiments, the first sheet 311 and the second sheet 312 can also be made into an integrated structure, but in this case, they are special-shaped components and the manufacturing cost is relatively high. Therefore, in this embodiment, the first shift piece 31 is set as a split structure, and the teeth and the first shift rod 313 are respectively arranged on the first sheet 311 and the second sheet 312. This structural form has low requirements on processing technology and low material cost.

[0029] The second paddle 32 and the first paddle 31 are provided with a first sliding block 322 and a first arc-shaped sliding groove 316 that are slidably assembled together. Figure 5a and Figure 5bAs shown, in this embodiment, the first slider 322 is arranged on the side of the second paddle 32, and the first slide groove 316 is arranged on the second sheet 312. At the same time, a locking rod 321 is arranged on the outer periphery of the second paddle 32, which can abut against the outer side of the inner end of the lock tongue 1 and bend inward. Figure 1 In the initial state shown, the first slider 322 abuts against the lower side of the first slide groove 316. When the peach assembly 4 is rotated to make the first paddle 31 move along the Figure 1 When the first slider 322 rotates counterclockwise, the first slider 322 slides relatively toward the upper side of the first slide groove 316, that is, only the first paddle 31 rotates, and the second paddle 32 does not rotate accordingly; when the peach assembly 4 is rotated so that the first paddle 31 moves along the Figure 1 When the lock 310 rotates clockwise, the first slider 322 will rotate clockwise under the drive of the lower side wall of the first slide groove 316, that is, the second paddle 32 will rotate clockwise. At this time, the locking rod 321 can abut against the outer side of the inner end of the lock tongue 1, that is, the reverse locking state.

[0030] In addition, the first spring 51 is arranged in the housing 2, and can apply a force to the second paddle 32, so that the locking rod 321 is tightly against the outer side of the inner end of the lock tongue 1. Specifically, in this embodiment, the first spring 51 is a torsion spring, one end of which is hinged on the fixed shaft 6 in the housing 2, and the other end is hinged on a fixed shaft 6 on the second paddle 32. In the reverse locking state, the force applied by the first spring 51 to the second paddle 32 makes it have a tendency to rotate clockwise; in the initial state, the force applied by the first spring 51 to the second paddle 32 makes it have a tendency to rotate counterclockwise. In other words, the other end of the first spring 51 rotates simultaneously with the second paddle 32. In the reverse locking state, the force applied by the first spring 51 to the second paddle 32 is located on the side of the axis of the second paddle 32 away from the lock tongue 1, and in the above initial state, the force applied by the first spring 51 to the second paddle 32 is located on the side of the axis of the second paddle 32 close to the lock tongue 1. In the two different states, the first torsion spring can make the locking rod 321 respectively abut against the lock tongue 1 or other structures in the housing 2, such as the side wall of the battery frame, so that the second paddle 32 is in a stationary state in the two states. In other embodiments, the torsion spring can also be replaced by a spring in a compressed state, which can also play the above role.

[0031] When the lock structure is applied to the door, the lock tongue 1 can be automatically locked by bringing it close to the magnetic buckle box on the door frame. Figure 1 By rotating the peach assembly 4 in the clockwise direction, the outer end of the lock tongue 1 can be retracted into the housing 2 to unlock the lock; if further locking is required, Figure 1By rotating the paddle assembly 4 in the counterclockwise direction, the locking rod 321 on the second paddle 32 can abut against the outer side of the inner end of the lock tongue 1, and under the action of the first spring 51, it is tightly pressed against the lock tongue 1 to achieve reverse locking. At this time, even if a strong magnetic device is used outside, the lock tongue 1 will not be moved, so that the lock body structure has a higher safety performance. In the reverse locking state, along Figure 2 and Figure 3 Rotating the peach assembly 4 in the clockwise direction can make the first paddle 31 rotate counterclockwise, and at the same time, the upper side of the first slide groove 316 gradually abuts against the first slider 322 to drive the second paddle 32 to rotate counterclockwise. At this time, the locking rod 321 is away from the outer side of the inner end of the lock tongue 1, and the first paddle 313 is close to the inner side of the inner end of the lock tongue 1. When releasing the anti-lock, it can also drive the lock tongue 1 to rotate to achieve unlocking. When realizing the above unlocking, anti-locking and releasing the anti-lock, there is only a rotation connection between the various components, and no large noise will be generated. Therefore, the lock body structure has high security and low noise while realizing the basic locking and anti-locking functions.

[0032] Please combine Figure 4 In this embodiment, the shift peach assembly 4 includes a first shift peach 41, a second shift peach 42 and a clutch 44. The first shift peach 41 is composed of two half shells, the middle of which is provided with a first cavity 411 and a second cavity 412 that are in communication, and the outer circumference thereof is provided with teeth that mesh with the first sheet 311. The first cavity 411 is used to accommodate the second shift peach 42. The first cavity 411 is circular, and one side of the cavity is provided with a first sliding hole 413 along the circumferential direction; the main body of the second shift peach 42 is circular and rotatably arranged in the first cavity 411, and one side of the second shift peach 42 is provided with a shift block 421 that is slidably assembled in the first sliding hole 413. The second cavity 412 is used to accommodate the clutch pin 43, as shown in FIG. Figure 4 As shown, the clutch pin 43 is slidably arranged in the second cavity 412, and a sliding cavity 414 is also arranged on the side of the second cavity 412, and a second spring 52 is arranged in the sliding cavity 414. A second protrusion 431 extending into the sliding cavity 414 is arranged on the side of the clutch pin 43, and the two ends of the second spring 52 respectively abut against the side of the second protrusion 431 and the end face of the sliding cavity 414, and exert a force toward the outer end to the clutch pin 43. In addition, a first groove 422 for inserting the clutch pin 43 is also arranged on the side of the second shifting peach 42. When the lower end of the clutch pin 43 is inserted into the first groove 422, the second shifting peach 42 of the first shifting peach 41 can rotate synchronously, and the two can rotate relative to each other. The clutch 44 is also arranged in the housing 2, and it can drive the clutch pin 43 to move inward and insert into the first groove 422 under preset conditions.

[0033] In the above initial state, the clutch pin 43 is not inserted into the first groove 422, the shift block 421 abuts against one side of the first sliding hole 413, and the second shift peach 42 can only drive the first shift peach 41 to rotate along the direction of the reverse locking bolt 1, that is, at this time, the second shift peach 42 is only Figure 1 When the first shifting peach 41 is rotated counterclockwise, the first shifting peach 41 can be driven to rotate. Otherwise, the first shifting peach 41 can only slide in the first sliding hole 413 and cannot drive the first shifting peach 41 to rotate. Under this structure, the first shifting peach 41 and the second shifting peach 42 can be connected to the handles inside and outside the door respectively. For example, an inner handle whose inner end rotates synchronously with the first shifting peach 41 is provided on the inner side of the door, and an outer handle whose inner end rotates synchronously with the second shifting peach 42 is provided on the outer side of the door. Accordingly, the outer end of the inner handle or the outer handle is lifted up so that it moves along the Figure 1 When the outer end of the inner handle is pressed down or the outer end of the outer handle is pressed down when the clutch pin 43 is inserted into the first groove 422, the first peach 41 can be driven to rotate in the opposite direction to release the anti-lock and unlock; and when the clutch pin 43 is not inserted into the first groove 422, the outer end of the outer handle is pressed down, and the first peach 41 will not be driven to rotate. In other words, in the anti-lock state, only when the clutch pin 43 is inserted into the first groove 422, the outer handle can be rotated clockwise to drive the first peach 41 to rotate through the second peach 42, thereby releasing the anti-lock and unlocking. The safety performance of the lock is further improved.

[0034] In this embodiment, the clutch 44 includes a pressure plate 441 disposed at the outer end of the clutch pin 43, wherein when the outer end of the inner handle or the outer handle is lifted, the clutch 44 drives the pressure plate 441 away from the clutch pin 43, and at the same time, the inner end of the clutch pin 43 leaves the first groove 422 under the push of the second spring 52. The realization of this function can be triggered by an electronic switch, for example, an electronic switch is arranged on the path of the first paddle 41 rotating counterclockwise, and when the outer end of the inner handle or the outer handle is lifted, the electronic switch is triggered, and then the clutch 44 drives the pressure plate 441 away from the clutch pin 43. Through this structure, whether the user is from the inside or outside of the door, after the lock body is locked, the clutch pin 43 can be left from the first groove 422, and then the outer handle cannot be pressed down from the outside of the door to achieve the release of the lock and unlocking. In addition, there are a variety of structures in the prior art that can realize the movement of the pressure plate 441, so the specific structure of the clutch 44 is not repeated here.

[0035] In addition, in this embodiment, the lock body structure also includes a verification module and a control module. Among them, the verification module is used to verify the identity of the user, and can be a fingerprint recognition module, a face recognition module, a password verification module, etc. The control module is a processor with a logic operation function, which is connected to the verification module and the clutch 44. After the user identity verification is passed, the clutch 44 drives the pressure plate 441 to approach the clutch pin 43, and inserts the inner end of the clutch pin 43 into the first groove 422, and then the outer handle can be turned to unlock. Therefore, through these two modules, the user can release the anti-lock and unlock after completing the identity recognition on the side outside the door.

[0036] In addition, in this embodiment, a second lever 323 is provided on the outer periphery of the second paddle 32, and a third shifting peach 7 is provided in the housing 2 as an emergency shifting peach, the center of which is a cross hole. In an emergency, the third shifting peach 7 can be rotated through the reserved hole on the housing 2 and the corresponding accessories. A third lever 71 is provided on the outer periphery of the third shifting peach 7. When the third shifting peach 7 moves along the Figure 1 When the third lever 71 rotates clockwise, it can abut against the side of the second lever 323, and drive the second paddle 32 to rotate counterclockwise to make the locking rod 321 away from the lock tongue 1, thereby releasing the reverse lock. With this structure, the reverse lock state of the lock body can be released when the handle, the peach assembly 4, the verification module, the control module and other parts are abnormal.

[0037] Furthermore, in this embodiment, the driving assembly 3 further includes a third paddle 33 coaxially arranged with the second paddle 32. A fourth lever 331 located inside the inner end of the lock tongue 1 and a fifth lever 332 close to one side of the third paddle 7 are provided on the outer periphery of the third paddle 33, wherein when the third paddle 7 rotates clockwise, the third lever 71 can abut against the side of the fifth lever 332, and drive the third paddle 33 to rotate counterclockwise so that the fourth lever 331 abuts against the inner end of the lock tongue 1, thereby driving the lock tongue 1 to rotate so that its outer end is retracted into the housing 2. After adding this structure, when the anti-lock state of the lock body is released by the third paddle 7, the lock tongue 1 can also be driven to rotate at the same time to achieve unlocking.

[0038] In addition, a second slider 333 and an arc-shaped second slide groove 324 are provided on the opposite sides of the second paddle 32 and the third paddle 33. Figure 5a and Figure 5b As shown, the second slider 333 is disposed on the third paddle 33, and the second slide groove 324 is disposed on the second paddle 32, so that the second paddle 32 and the first paddle 31 can rotate relative to each other and rotate synchronously. Figure 1 In the initial state, the second slider 333 is close to the left side of the second slide groove 324. When the lock is reversed, the second slider 333 slides relatively in the second slide groove 324 and does not drive the third paddle 33 to rotate. Figure 2In the middle anti-lock state, the second slider 333 is close to the right side of the second slide groove 324. When the anti-lock is released, the second slider 333 slides relatively in the second slide groove 324, and also does not drive the third paddle 33 to rotate. Therefore, in normal use, the third paddle 33 is in a relatively stable state.

[0039] Furthermore, a third spring 53 is provided in the second slide groove 324, and two ends of the third spring 53 abut against the end surface of the second slide groove 324 and the side surface of the slider, respectively. The third spring 53 can improve the stability of the third paddle 33, and when the second paddle 32 rotates, the third paddle 33 will not rotate significantly, ensuring that the lock tongue 1 is in a relatively stable state.

[0040] In addition, a second arc-shaped sliding hole 21 is provided on the side wall of the shell 2, and a sliding rod 325 slidably assembled in the second sliding hole 21 is provided on the side of the second paddle 32, thereby further limiting the rotation range of the second paddle 32 and improving the stability of the second paddle 32.

[0041] In addition, in this embodiment, the peach assembly 4 also includes a fourth spring 54. Figure 2 and Figure 4 The fourth spring 54 is a torsion spring, and a convex block located between two torsion arms of the fourth spring 54 is provided on the side of the first plate 311, and a convex block located between two torsion arms of the fourth spring 54 is also provided on the housing 2.
