Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.

One of the important structural components of a door is a door lock, which controls the door to open and close a room, space, etc. The electric lock body is one of important structural parts on the door lock. In the related art, a purely mechanical door lock structure is usually adopted, that is, a key is used for driving a structure in the door lock to move so as to realize opening and closing of the door. With the development of technology and the changing of user's demand, electronic locks are now in the field of vision of people and are well noticed by users. The electronic lock does not need to use a key under the conventional condition, and the door can be opened and closed only by means of face recognition, password input, fingerprint input, voice recognition and the like through the built-in circuit to automatically drive the structure in the door lock to move. This brings great convenience and a sense of user experience. However, once a motor, a circuit structure or other structural members in the motor lock have a fault, and a problem occurs in a certain link in the motor lock, the motor lock cannot work normally, and a user outside the door cannot open the door to enter a room by using an electronic lock door opening method and can only enter the room by using a key door opening method. And the user in the door also can not open the door and walk out of the room, and at the moment, only a violent dismantling method can be adopted for the door or the door lock, so that irreversible loss is caused to the door, and the difficulty and the risk of unlocking are greatly increased.

In view of the above, in order to solve the above problems, the present application provides an electric lock body, please refer to fig. 1 to 7 together, and fig. 1 is a schematic perspective view of an electric lock body according to an embodiment of the present application. Fig. 2 is a top view of fig. 1. FIG. 3 is a schematic cross-sectional view taken along the line A-A of FIG. 2 according to an embodiment of the present disclosure. Fig. 4 is a schematic cross-sectional view along the direction a-a in another embodiment of the present application. Fig. 5 is a schematic perspective view of a driving mechanism according to an embodiment of the present application. FIG. 6 is a top view of a portion of a drive mechanism in an embodiment of the present application. FIG. 7 is a top view of a portion of a drive mechanism in another embodiment of the present application. The embodiment provides an electric lock body 1, the electric lock body 1 comprises a shell 10, and a housing space 11 is arranged in the shell 10. The driving mechanism 20 is arranged in the accommodating space 11, and the driving mechanism 20 comprises a motor 21, a planetary gear assembly 22 and a retainer 26; the planetary gear assembly 22 comprises a gear ring 23, a planet wheel 24 and a sun wheel 25, the motor 21 is rotationally connected with the sun wheel 25, the gear ring 23 has an accommodating space, the planet wheel 24 and part of the sun wheel 25 are both arranged in the accommodating space, and the planet wheel 24 is rotationally connected between the sun wheel 25 and the gear ring 23; and the retainer 26 is arranged on one side of the planetary gear assembly 22, the ring gear 23 and the sun gear 25 are both abutted against the retainer 26, and the planet gear 24 is connected with the retainer 26.

When the ring gear 23 is in a fixed state, the sun gear 25 is driven by the motor 21 to rotate, so that the planet gear 24 rotates relative to the ring gear 23, and the retainer 26 rotates; alternatively, when the sun gear 25 is in a fixed state, the ring gear 23 may be controlled to rotate, so that the planet gears 24 rotate relative to the sun gear 25, and the retainer 26 rotates.

And a locking bolt 30, at least a part of the locking bolt 30 is arranged in the accommodating space 11, the locking bolt 30 is connected with the holder 26, when the holder 26 rotates, the holder 26 can drive the locking bolt 30 to move, so that the locking bolt 30 is switched between an unlocking state accommodated in the shell 10 and a locking state protruding out of the shell 10.

The housing 10 provided in this embodiment is an appearance member of the electric lock body 1, and plays a role of protecting other components of the electric lock body 1 disposed in the housing 10, and the housing 10 may also provide a basis for installing some of the components.

The driving mechanism 20 provided in this embodiment is one of important structural members of the electric lock body 1. The driving mechanism 20 is a core component for driving the electric lock body 1 to move, that is, other components in the electric lock body 1 are driven to move by the movement of the driving mechanism 20, and finally the purpose of opening and closing the door is achieved.

The locking tongue 30 provided in the present embodiment is a direct component for finally unlocking and locking the electric lock body 1. Specifically, the method comprises the following steps: when the bolt 30 protrudes out of the housing 10, the bolt 30 can be engaged with a lock hole on a door frame or a wall, so that the door is locked and cannot be jammed, i.e. the electric lock body 1 is locked (as shown in fig. 3). When the locking bolt 30 is accommodated in the housing 10, the locking bolt 30 cannot engage with the lock hole, i.e. the locking bolt 30 is separated from the component, so that the door can be opened, i.e. the electric lock body 1 is in an unlocked state (as shown in fig. 4). Optionally, the housing 10 is provided with a through hole 12 communicating with the accommodating space 11, and the through hole 12 is used for enabling the latch 30 to protrude and be accommodated in the housing 10. As to how the latch tongue 30 protrudes from the housing 10 or is accommodated in the housing 10, the driving control is performed by the above-mentioned driving mechanism 20, and the detailed structure of the driving mechanism 20 will be described in detail.

The drive mechanism 20 provided in the present embodiment includes a motor 21. Wherein the motor 21 is operated and rotated by the power supply. Alternatively, the power source may be an external power source, or the power source may be internally disposed within the housing 10, such as a battery.

The present embodiment provides that the drive mechanism 20 further comprises a planetary gear assembly 22. Wherein the planetary gear assembly 22 is comprised of a plurality of structural members. For example, the planetary gear assembly 22 includes a ring gear 23, planet gears 24, and a sun gear 25. The names of the three structural members are all technical terms of the gear in the industry of the technical field. The gear ring 23 is a ring gear, an accommodating space is provided in the gear ring 23, and the gear ring 23 has a circle of internal teeth and a circle of external teeth. In addition, the planet wheel 24 and the sun wheel 25 both have a circle of external teeth, and the planet wheel 24 and a part of the sun wheel 25 are both arranged in the accommodating space. It can also be understood that a part of the sun gear 25 is disposed in the accommodating space, and the rest of the sun gear 25 is disposed outside the accommodating space. As for the motor 21, the sun gear 25 is rotatably connected. It can be understood that the motor 21 is rotatably connected to the sun gear 25 outside the accommodating space and drives the sun gear 25 inside the accommodating space to rotate. Second, the motor 21 is rotatably connected to the sun gear 25, and the motor 21 is directly connected to the sun gear 25. Or, another gear assembly 29 is further disposed between the motor 21 and the sun gear 25, one end of the gear assembly 29 is rotatably connected to the motor 21, and the other end of the gear assembly 29 is rotatably connected to the sun gear 25 disposed outside the accommodating space. The motor 21 rotates to drive the gear assembly 29 to rotate, and the gear assembly 29 rotates to drive the sun gear 25 arranged outside the accommodating space to rotate, and finally, the sun gear 25 in the accommodating space is driven to rotate. In this case, it can be seen that the motor 21 is indirectly rotationally coupled to the sun gear 25. As to the specific structure of the gear assembly 29, the present application will be described later.

Next, the planet gears 24 are rotatably connected between the sun gear 25 and the ring gear 23. It is also understood that one end of the planet wheel 24 is rotationally connected to the internal teeth of the ring gear 23, and the opposite end of the planet wheel 24 is rotationally connected to the external teeth of the sun wheel 25. The whole planetary wheel 24 assembly is linked by three gears of a gear ring 23, a planetary wheel 24 and a sun wheel 25 through the planetary wheel 24. Alternatively, the number of the planet wheels 24 can be multiple, and each planet wheel 24 is arranged at equal intervals. For example, the number of the planetary wheels 24 is 3, and each planetary wheel 24 is arranged 120 ° apart. This improves the rotational stability of the planet 24 assembly and the carrier 26.

The present embodiment provides that the drive mechanism 20 further includes a cage 26, wherein the cage 26 is a carrier that mounts the planetary gear assembly 22, as well as other structural components. And the bracket may also be coupled to other components outside of the drive mechanism 20 to transmit the motion of the cage 26 to the other components. For example, the planetary gear assembly 22 is disposed on one side of the cage 26 and the latch 30 is coupled to the other side of the cage 26. The ring gear 23 and the sun gear 25 of the planetary gear assembly 22 each abut against the cage 26, and the planet gears 24 are connected to the cage 26. Thus, the movement state of the carrier 26 is not affected by the rotation of the ring gear 23 and the sun gear 25. The planet gears 24 are connected to the cage 26, so that rotation of the planet gears 24 causes the cage 26 to rotate together. Rotation of holder 26 may further cause movement of locking bolt 30.

The above description is a mechanical structure of the drive mechanism 20 provided in the present embodiment. As to how the movement of the drive mechanism 20 is specifically effected. This embodiment can finally make planet wheel 24 rotate through the mutually supporting of ring gear 23, planet wheel 24 and sun gear 25, and then drive holder 26 and rotate, thereby finally drive the motion of the spring bolt 30 of connecting holder 26 and realize the switch door. The specific matching method of the ring gear 23, the planet gear 24 and the sun gear 25 can be as follows: by structurally fixing either the ring gear 23 or the sun gear 25, the other of the ring gear 23 or the sun gear 25 is in rotational engagement with the planet gears 24, so that the planet gears 24 can revolve around the sun gear 25 to rotate the cage 26. For example, when the ring gear 23 is in a fixed state, the sun gear 25 is driven by the motor 21 to rotate, so that the planet gear 24 rotates relative to the ring gear 23, and further drives the holder 26 to rotate, and finally drives the latch 30 connected to the holder 26 to move, thereby opening and closing the door. When the motor 21 fails and cannot normally operate, the sun gear 25 cannot rotate, and at this time, the sun gear 25 is in a fixed state, so that the ring gear 23 can be directly controlled to rotate, so that the planet gears 24 rotate relative to the sun gear 25, and the retainer 26 is further driven to rotate. Thus, even when the motor 21 fails, the door can be opened and closed by controlling the ring gear 23 to rotate.

In addition, in the related art, the electric lock body 1 is installed inside the door, and the driving mechanism 20 is installed outside the door. However, in the present embodiment, the driving mechanism 20 is provided in the housing space 11 in the housing 10, that is, the driving mechanism 20 is also provided in the door, so that the structure outside the door can be simplified, and the whole door can be seen more simply. And if electronic lock body 1 damages, only need with the electronic lock body 1 whole replacement in the door can, be convenient for maintain and replace.

Optionally, referring to fig. 1, fig. 3, and fig. 4 again, as to how to fix and rotate the ring gear 23, the electric lock body 1 of the present embodiment further includes a control mechanism 28, at least a portion of the control mechanism 28 is disposed in the accommodating space 11, the control mechanism 28 is connected to the ring gear 23, the control mechanism 28 has a fixed state and a rotating state, and the control mechanism 28 is configured to control the ring gear 23 to be fixed or rotated. In the present embodiment, the control mechanism 28 can be connected to the ring gear 23 by adding the control mechanism 28. Since the control mechanism 28 has a fixed state and a rotating state. When the control mechanism 28 is fixed, the ring gear 23 is fixed, and the sun gear 25 is rotated by the motor 21 to rotate the planet gears 24 relative to the ring gear 23. When the control mechanism 28 is turned, the ring gear 23 is caused to rotate, while the sun gear 25 is in a fixed state, so that the planet gears 24 rotate relative to the sun gear 25.

Further alternatively, the control mechanism 28 includes, but is not limited to, a key cylinder structure, i.e., a key that cooperates with the key cylinder structure to effect the securing and rotation. Or other mechanism with a driving function.

Further alternatively, the motor 21 and the control mechanism 28 are disposed on the same side of the assembly of planet wheels 24. This can simplify the structure of the electric lock body 1, thereby reducing the overall size of the electric lock body 1.

Alternatively, referring again to fig. 6-7, the gear assembly 29 includes a first gear 291, a second gear 292, and a third gear 293, the first gear 291 being rotatably coupled to the motor 21, the second gear 292 being rotatably coupled to the first gear 291, and the third gear 293 being rotatably coupled to the second gear 292. The rotation of the motor 21 can be transmitted to the sun gear 25 through a plurality of gears, thereby improving the stability and controllability of the rotation of the sun gear 25.

Optionally, referring to fig. 6-7 again, in this embodiment, the driving mechanism 20 further includes a worm wheel 294 and a worm 295, the worm 295 is connected to the motor 21, one end of the worm wheel 294 is rotatably connected to the worm 295, and the other end of the worm wheel 294 is rotatably connected to the gear assembly 29.

While it is mentioned above that the rotation of the motor 21 can be transmitted to the sun gear 25 through the gear assembly 29, in this embodiment, a worm wheel 294 and a worm 295 can be further added between the motor 21 and the gear assembly 29. Wherein, the worm 295 is connected with the motor 21, one end of the worm wheel 294 is rotatably connected with the worm 295, and the other end of the worm wheel 294 is rotatably connected with the gear assembly 29. The rotation of the motor 21 is transmitted to the gear ring 23 through the matching of the worm wheel 294 and the worm 295, the single-stage speed ratio of the worm wheel 294 and the worm 295 is large, the noise is small during rotation, and the vibration is small. The worm wheel 294 and the worm 295 have a self-locking function. The self-locking function is understood to mean that the rotatable worm gear 294 rotates when the worm 295 rotates, but the worm gear 294 is locked when the worm 295 is not in motion. In addition, the worm wheel 294 is perpendicular to the worm 295, so that the arrangement direction of the motor 21 can be changed, thereby simplifying the structure of the driving mechanism 20 and reducing the overall size of the electric lock body 1.

Optionally, referring again to fig. 5, the driving mechanism 20 may further include a protective casing 27, and the protective casing 27 is used for protecting part of the structural components of the driving mechanism 20, such as the worm wheel 294, the worm 295, the planetary gear assembly 22, the gear assembly 29, and the like.

In summary, the electric lock body 1 provided by the present application first makes the motor 21 rotationally connected to the sun gear 25 by providing the planetary gear assembly 22, that is, the motor 21 can control the rotation of the sun gear 25. Secondly, the planet gears 24 are connected to the cage 26, i.e. the planet gears 24 control the rotation of the cage 26. Again, the locking tongue 30 is connected to the holder 26, i.e. the holder 26 may control the movement of the locking tongue 30.

The above mentions that the final movement of the drive mechanism 20 results in the rotation of the planet wheel 24, which in turn rotates the cage 26 connected to the planet wheel 24 and in turn the movement of the latch tongue 30 connected to the cage 26. In this embodiment, the electric lock body 1 further includes an actuating mechanism 40, one end of the actuating mechanism 40 is connected to the holder 26, and the other end of the actuating mechanism 40 is connected to the locking tongue 30, that is, the holder 26 and the locking tongue 30 are indirectly connected through the actuating mechanism 40.

Please refer to fig. 3-4, fig. 8, and fig. 8 are schematic perspective views of a part of the driving mechanism 20 and a part of the transmission mechanism 40 according to an embodiment of the present application. In this embodiment, the transmission mechanism 40 includes an output gear 41, a rack 42, and a latch pulling plate 43, the output gear 41 is connected to the holder 26, the output gear 41 is engaged with the rack 42, the rack 42 is connected to the latch pulling plate 43, and the latch pulling plate 43 is connected to the latch 30.

Thus, when the holder 26 rotates, the holder 26 rotates the output gear 41 and thus moves the rack 42, which converts the rotation into linear movement. Movement of rack 42 moves deadbolt pull plate 43 and ultimately deadbolt 30. Drive tongue 30 through drive mechanism 40 and remove, can improve the stability and the controllability that tongue 30 removed.

Referring to fig. 3-4, 8, and 9, fig. 9 is a top view of a portion of the driving mechanism 20 and a portion of the transmission mechanism 40 according to an embodiment of the present disclosure. In this embodiment, the planet gear 24 is connected to one side of the holder 26, the buffer groove 270 is formed in the other side of the holder 26 opposite to the one side, and the first protruding portion 271 is protruded from the side wall of the holder 26 where the buffer groove 270 is formed.

The transmission mechanism 40 further includes a connecting member 44, the output gear 41 is disposed on the connecting member 44, a second protruding portion 442 is disposed on a periphery of the connecting member 44, at least a portion of the second protruding portion 442 is disposed in the buffer slot 270, and each second protruding portion 442 is disposed between two adjacent first protruding portions 271.

The electric lock body 1 further includes a buffer member 45, the buffer member 45 is disposed in the buffer slot 270, and the buffer member 45 abuts between the first protruding portion 271 and the second protruding portion 442.

In the present embodiment, the output gear 41 is first connected to the carrier 26 not rigidly but flexibly. Second, the output gear 41 is not directly connected to the carrier 26. Specifically, the transmission mechanism 40 further includes a connecting member 44, and the output gear 41 is disposed on the connecting member 44 and flexibly connected to the holder 26 by the connecting member 44, so that the output gear 41 is indirectly connected to the holder 26. Also, the planetary gear 24 is connected to one side of the carrier 26, and the output gear 41 and the connecting member 44 are connected to the other side of the carrier 26, thereby simplifying the structure of the transmission mechanism 40.

Further, a buffer groove 270 is formed on the other side of the holder 26, and a plurality of first protrusions 271 are projected from the side wall of the buffer groove 270. The buffer groove 270 is used for accommodating at least a part of the buffer 45 and the connecting element 44, the connecting element 44 is used for connecting the output gear 41, besides, a plurality of second protrusions 442 arranged at intervals are further arranged on the outer peripheral side wall of the connecting element 44, and each second protrusion 442 is arranged between two adjacent first protrusions 271. It can also be understood that the second protrusions 442 are staggered with the first protrusions 271. A buffer 45 may be disposed between each of the first and

second protrusions

271 and 442, that is, opposite ends of the buffer 45 are connected to the first and

second protrusions

271 and 442, respectively. Optionally, the buffer 45 is a structural member with elasticity, and optionally, the buffer 45 may be a spring or an elastic foam or the like.

First, in this embodiment, the first protrusion 271 and the second protrusion 442 are connected by the buffer 45, so that the holder 26 is connected to the transmission connector 44, and further the holder 26 is connected to the transmission mechanism 40, that is, when the holder 26 rotates, the transmission mechanism 40 and the tongue pulling plate 43 are driven to move. Secondly, since the buffer member 45 has a buffering performance, the flexible connection of the retainer 26 and the transmission mechanism 40 can be realized by the buffer member 45, for example, when the output gear 41 and the rack 42 are blocked during transmission, the buffer member 45 can elastically compress and absorb stress by a reaction force. When the output gear 41 is rotated in the reverse direction, the buffer 45 can release the compressive stress to push the drive gear to rotate in the reverse direction. This makes it possible to use the cushion member 45 not only to absorb the excessive stress but also to use the stress to rotate the output gear 41 in the reverse rotation. Therefore, the clamping stagnation phenomenon in the transmission of the output gear 41 can be effectively prevented, and the force required in the reverse motion can be effectively reduced.

When the electric lock body 1 is in a locked state, as shown in fig. 3 and 11, the locking tongue 30 and a part of the positioning mechanism 50 are protruded from the housing 10. When the electric lock body 1 is in the unlocked state, as shown in fig. 12, the locking bolt 30 and a part of the positioning mechanism 50 are both accommodated in the housing 10.

The present embodiment also provides a specific structure of the positioning mechanism 50. The positioning mechanism 50 is mainly formed by the cooperation of the top rod 522, the latch tongue 532 and the latch tongue pulling hook 54, so as to be protruded and contained in the housing 10.

The fixing member 51 mainly serves as a part of a structural member for fixing the positioning mechanism 50, and the fixing member 51 is provided with a first through hole 511 and a second through hole 512 which are arranged at an interval. The first link 521, the lift pin 522, and the first elastic member 523 are a set of components of the positioning mechanism 50, wherein one end of the first link 521 passes through the first through hole 511, the other end of the first link 521 is connected to the lift pin 522, and at least a portion of the lift pin 522 is disposed in the accommodating space 11. Thus, the first link 521 can move in the first through hole 511, thereby moving the top rod 522. And the first elastic member 523 connects the top rod 522 with the fixed member 51, so that when the first link 521 is moving, the first elastic member 523 can have a compressed state and a stretched state. In addition, a third through hole 524 is formed in the first link 521, and the third through hole 524 is used for being subsequently matched with the latch tongue pulling hook 54.

Thus, the second link 531 can move in the second through hole 512, thereby moving the latch 532. And a second elastic member 533 connects the top bar 522 with the fixed member 51. Thus, the second link 531 can make the second elasticity have a compressed state and a stretched state when moved.

The latch tongue pulling hook 54 is rotatably connected with the latch tongue pulling plate 43, and the latch tongue pulling hook 54 comprises a first part 541 and a second part 542 which are connected, and the first part 541 and the first connecting rod 521 are matched with each other to control the movement of the top rod 522. The first positioning portion 543 and the second positioning portion 544 are matched with each other to control the movement of the latch 532. The latch tongue pulling hook 54 is used as a part for connecting the top rod 522 and the latch tongue 532, and when the top rod 522 or the latch tongue 532 moves, the other one can move together through the latch tongue pulling hook 54.

In addition, referring to fig. 10 to 12, in this embodiment, the positioning mechanism 50 further includes a third elastic member 55, and the third elastic member 55 connects the tongue pulling plate 43 and the latch tongue pulling hook 54.

In this embodiment, a third elastic member 55 may be further added, and the third elastic member 55 connects the tongue pulling plate 43 and the latch tongue pulling hook 54. When the top rod 522 or the latch tongue 532 moves, the latch tongue pulling hook 54 rotates and drives the other latch tongue pulling hook to move together, and at the moment, the third elastic part 55 deforms, so that the latch tongue pulling hook 54 has the capability of recovering the initial state, and the repeated movement of the latch tongue pulling hook 54 is facilitated.

The present embodiment also describes the detailed movement of the positioning mechanism 50. When the electric lock body 1 is in the locked state from the positioning state, as shown in the process from fig. 10 to fig. 11, a part of the ejector 522 and a part of the latch 532 protrude from the housing 10, that is, after a user performs positioning before locking by using the positioning mechanism 50, the driving mechanism 20 drives the latch pulling plate 43 to drive the latch 30 to move, so that a part of the latch 30 protrudes from the housing 10;

when the electric lock body 1 is in the locked state to the unlocked state, that is, when a user needs to open the door, as shown in the process from fig. 11 to fig. 12, the driving mechanism 20 drives the bolt pulling plate 43 to drive the bolt 30 to move, so that the bolt 30 is accommodated in the accommodating space 11; in the process of moving the tongue pulling plate 43, the second positioning portion 544 can abut against the first positioning portion 543 and drive the latch tongue 532 to move, so that the latch tongue 532 is accommodated in the accommodating space 11, and the second elastic member 533 is in a compressed state; the first portion 541 can abut against a sidewall of the first link 521, which opens the third through hole 524, and drive the top rod 522 to move, so that the top rod 522 is accommodated in the accommodating space 11, and the first elastic member 523 is in a compressed state. At this time, the first elastic member 523 and the second elastic member 533 are both in a compressed state.

When the electric lock body 1 is in the unlocked state to the positioning state, that is, after a user opens a door, as shown in the process from fig. 12 to fig. 10, the top bar 522 and the first link 521 are driven by the first elastic member 523 to move, so that a portion of the top bar 522 protrudes out of the housing 10, and in the process of moving the first link 521, a side wall of the first link 521, which opens the third through hole 524, may abut against the first portion 541, and drive the latch pull hook 54 to rotate relative to the latch pull plate 43, so that the first positioning portion 543 is separated from the second positioning portion 544, and the latch 532 and the second link 531 are driven by the second elastic member 533 to move, so that a portion of the latch 532 protrudes out of the housing 10.

In summary, when the electric lock body 1 is unlocked, the latch tongue pulling plate 43 is linked with the latch tongue pulling hook 54 to drive the latch tongue 532 to retract into the accommodating space 11, after the door is opened, the push rod 522 is ejected outwards under the action of the first elastic member 523, and the latch tongue pulling hook 54 is linked to rotate and release the latch tongue 532 to eject and reset in the ejection process. Through the mutual cooperation of the above parts, various problems of the lock in the related art are solved. For example, the door is not opened, the latch tongue 532 can not be ejected, and the problem of false locking is effectively overcome. In addition, the positioning mechanism 50 provided in this embodiment is driven by the elastic elements (the first elastic member 523 and the second elastic member 533), and does not need to be driven by a motor, thereby reducing the failure rate of the electric lock body 1.

Please refer to fig. 13-14 together, fig. 13 is a partial structural schematic diagram of the electric lock body 1 in an embodiment of the present application when it is normal. Fig. 14 is a partial structural schematic view of the electric lock body 1 when the ground lock 61 is jammed according to an embodiment of the present application. In this embodiment, the electric lock body 1 further includes a top and bottom lock mechanism 60, at least a portion of the top and bottom lock mechanism 60 is disposed in the accommodating space 11, the top and bottom lock mechanism 60 includes a top and bottom lock 61, a third portion 62, a fourth portion 63, and a fourth elastic member 64, the top and bottom lock 61 is slidably connected to the housing 10, one end of the third portion 62 and one end of the fourth portion 63 are both rotatably connected to the housing 10, the other end of the third portion 62 is slidably connected to the tongue pulling plate 43, and the other end of the fourth portion 63 is slidably connected to the top and bottom lock 61; the fourth elastic member 64 connects the third portion 62 and the fourth portion 63.

In the electric lock body 1, in addition to locking and unlocking by the bolt 30, the present embodiment is additionally provided with the top and bottom lock mechanism 60, the top and bottom lock mechanism 60 can be understood as an auxiliary lock, and the top and bottom lock mechanism 60 can also be locked and unlocked, thereby further improving the safety and the theft prevention of the electric lock body 1. In the related art, the top-bottom lock 61 and the latch tongue 30 are rigidly connected, that is, the movement of the latch tongue 30 can drive the top-bottom lock 61 to move together. However, when the day lock 61 is stuck, the day lock 61 and the locking tongue 30 cannot be unlocked and locked effectively as normal.

The top-bottom lock mechanism 60 of the present embodiment thus includes a top-bottom lock 61, a third portion 62, a fourth portion 63, and a fourth elastic member 64. The third portion 62 and the fourth portion 63 may form a driving rocker arm, and the third portion 62 and the fourth portion 63 are both rotatably connected to the housing 10, that is, the third portion 62 and the fourth portion 63 are split structures, and the third portion 62 and the fourth portion 63 rotate independently. The other end of the third portion 62 is slidably connected to the latch tongue pulling plate 43, and the other end of the fourth portion 63 is slidably connected to the top and bottom lock 61, that is, the movement of the latch tongue pulling plate 43 can drive the third portion 62 to rotate, and the movement of the top and bottom lock 61 can also drive the fourth portion 63 to rotate. In addition, the fourth elastic member 64 connects the third portion 62 and the fourth portion 63. Fourth elastic member 64 may be used to connect third portion 62 and fourth portion 63 and to flexibly connect locking bolt 30 with top-bottom lock 61.

In a normal state, for example, during locking, as shown in fig. 13, the tongue pulling plate 43 is linked to the third portion 62 to rotate when the tongue 30 is driven to protrude from the housing 10, and the rotation of the third portion 62 can be transmitted to the fourth portion 63 through the third elastic member 55, so that the fourth portion 63 also rotates to drive the top-bottom lock 61 to protrude from the housing 10. However, once there is a jamming in the transmission process, such as a jamming in the structure of the top-bottom lock 61, as shown in fig. 14, the tongue pulling plate 43 can also drive the tongue 30 to protrude from the housing 10, and also link the third portion 62 to rotate. However, when the top-bottom lock 61 is stuck, that is, the top-bottom lock 61 cannot move stably, it can also be understood that the fourth portion 63 cannot rotate stably, and at this time, the fourth elastic element 64 can absorb the rotation force generated by the rotation of the third portion 62, so that the latch 30 moves normally, and the phenomenon that the latch 30 cannot lock the door normally due to the sticking of the top-bottom lock 61 is effectively prevented. When the lock tongue 30 drags back, the lock tongue rigidly drives the lock body 61 to move, so that the normal operation of opening and locking the door can be effectively ensured through the mutual matching of the above components.

Referring to fig. 3 to fig. 4 again, in this embodiment, the electric lock body 1 further includes a guiding mechanism 70 disposed in the accommodating space 11, the guiding mechanism is rotatably connected to the housing 10, and the guiding mechanism 70 is configured to cooperate with the lock tongue pulling plate 43 to move the lock tongue pulling plate 43 along a predetermined direction.

In this embodiment, a guiding mechanism 70 may be further added, and the guiding mechanism 70 is matched with the tongue pulling plate 43, so that the tongue pulling plate 43 moves along a predetermined direction, even if the tongue 30 can move along the predetermined direction, the tongue 30 protrudes out of the housing 10 and is accommodated in the housing 10 more stably. Alternatively, the guide mechanism 70 includes, but is not limited to, a guide pulley.
