Description

Technical Field

[0001] The present invention relates to the field of locks, and particularly to an electronic lock. Background Art

[0002] Anti-theft locks need to be configured on the anti-theft doors in families and public places, etc. The anti-theft locks can be generally divided into two types: mechanical anti-theft locks and intelligent anti-theft locks. Whether it is a mechanical lock or an intelligent lock, the lock body is one of the most important components; the functions that need to be realized on the lock ultimately need to be achieved through the movement of the components in the lock body. The lock body is the final execution component. It can be said that the functions and quality of the lock body directly determine the functions and quality of the whole lock; with the development of society, the application of intelligent locks is becoming more and more extensive, which requires the lock body to better meet the functional requirements of intelligent locks; at present, there are still many intelligent locks that use mechanical lock bodies, so all the intelligent functions can only be concentrated in the front and rear panels. This results in the need for a relatively large volume of the panel to accommodate various electronic components. At the same time, due to the relatively simple functions of the mechanical lock body, many intelligent functions in the whole lock are difficult to achieve; therefore, each lock enterprise is researching and developing and producing lock bodies with new structures to better meet the requirements of intelligent locks, and at the same time is committed to transferring some electronic components into the lock body, which not only greatly improves the performance of the whole lock, but also provides convenience for the development of various intelligent functions; however, due to the relatively short development time of the electronic lock body, various functions and structures are not yet perfect, and far from meeting the usage requirements of intelligent locks, which is also one of the very important factors restricting the development of intelligent locks.

[0015] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0016] 1. The lock body has strong versatility and can be applicable to various door opening methods without the need for commutation: The lock body of the present invention can be applicable to various forms of complete locks by replacing a small number of different components. For example, it can be generally applicable to mechanical locks, semi - automatic locks, and fully automatic locks; split locks and integral locks; true insertion core locks and false insertion core locks; upper handle locks and lower handle locks; self - elastic locks and non - self - elastic locks, etc.

[0017] 2. Adopting a unique cross - tongue structure to solve the problems of commutation and insufficient bearing capacity: Most lock bodies generally adopt an inclined tongue structure, which inevitably brings commutation problems, while the cross - tongue structure can achieve a two - way opening function; and a unique strengthening structure, support, and clutch structure are adopted to achieve the purposes of no need for commutation, high strength, and strong bearing capacity.

[0018] 3. Adopting a set of unique opening - closing clutch mechanisms, the clutch mechanism is driven by the cooperation of the triangular tongue structure and the cross - tongue mechanism to realize the opening - closing clutch function of the main lock mechanism; at the same time, the clutch plate cooperates with the micro - switch, and the electronic switch is triggered by the clutch plate to provide on - off signals; the greatest advantage of this design is that the on - off signals of the electronic switch directly reflect the opening - closing clutch state of the main lock mechanism, making the provided signals more real and effective, while the structure is simpler, the stability is higher, the cost is lower, and the performance is more excellent.

[0019] 4. Adopting a new type of transmission structure and clutch structure, the transmission ratio is greatly increased, which can ensure that a smaller torque output by the motor can drive the opening - closing lock mechanism, so that a motor with a smaller power can be used, greatly reducing the power consumption of the motor; at the same time, the new type of clutch structure adopted in the transmission structure can ensure that the clutch structure opens when the load reaches a certain level, and the motor is in an idling state, avoiding the problem of the motor being overloaded and burned out.

[0020] 5. A unique escape linkage mechanism is adopted and linked with the handle sleeve mechanism to achieve a one-way escape function: regardless of the opening method, only the inner side of the door can unlock the safety lock, and the outer side of the door cannot be opened; thus solving the problem that the anti-lock function commonly existing in current intelligent locks is ineffective;

[0021] 6. The sleeve for driving the lock body by the handle adopts a unique split form, enabling the inner and outer handles to act separately without affecting each other. The advantage of this method is that different functions can be realized for the inner and outer handles, such as the one-way escape function, etc. At the same time, the operating force of the handle is reduced, and the user experience is better;

[0022] 7. The types of components are greatly reduced, which can minimize the types and inventory of raw materials and various components to the greatest extent, reduce capital backlog, and greatly reduce the management costs of the supply chain and warehousing logistics.

[0023] 8. This lock body provides a wide degree of freedom for the development of the functions and appearance of the lock. The lock can be more diversified and personalized without the need to select different lock bodies for different designs; secondly, it provides greater convenience for aspects such as the installation and after-sales service of the lock. Since the types of lock bodies are reduced, and the installation is convenient and there is no need to change directions, the consistency and stability of the lock are higher, and various management costs will be greatly reduced.

DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0036] like Figures 1 to 9 An electronic lock shown includes a lock shell 1 and a side panel 2 arranged on one side of the lock shell 1, and a main lock mechanism 100, a cross tongue mechanism 200, an opening and closing clutch mechanism 300, an anti-locking mechanism, an escape mechanism 500, a top and bottom hook mechanism 600 and an unlocking mechanism 700 are respectively arranged in the lock shell 1.

[0037] Specifically, the main lock mechanism 100 includes a main lock tongue plate 3 which is laterally slidably arranged in the lock housing 1 and a square tongue 4 which is spaced apart on the main lock tongue plate 3 and can extend out of the side panel 2. The square tongue 4 can extend out or retract into the side panel 2 to achieve locking and opening.

[0038] Specifically, the cross-tongue mechanism 200 includes a transversely slidable inclined tongue plate 5 arranged in the lock housing 1, and an inclined tongue 6 is hingedly arranged up and down at one end of the inclined tongue plate 5. The two inclined tongues 6 can extend out of the side panel 2 and the inclined surfaces are arranged opposite to each other. A reinforcing support block 19 is provided on the upper and lower sides of the inclined tongue 6 and on one side close to the side panel 2. A limit plate 7 that can block the inclined tongue plate 5 from moving into the lock is provided vertically in the lock housing 1. The main lock tongue plate 3 moves into the lock so as to drive the limit plate 7 to disengage from the inclined tongue plate 5. When the main lock tongue plate 3 moves into the lock, a toggle cylinder 101 is installed on the main lock tongue plate 3. The toggle cylinder 101 will push the arc surface 102 on the limit plate 7, so that the limit plate 7 moves upward and disengages from the inclined tongue plate 5, and the inclined tongue plate 5 can move into the lock.

[0039] Specifically, the opening and closing clutch mechanism 300 includes a triangular tongue 8 that is laterally slidably arranged in the lock housing 1, a clutch paddle 9 is hinged at the rear end of the triangular tongue 8, a micro switch is arranged in the lock housing 1, a clutch plate 11 is vertically slidably arranged in the lock housing 1, and a pressing portion 12 that can press the micro switch is arranged at the upper end of the clutch plate 11. The triangular tongue 8 is located on the outer side of the side panel 2. When the triangular tongue 8 is retracted into the lock housing 1, the clutch paddle 9 can move the clutch plate 11 to move so that the pressing portion 12 is disengaged from the micro switch, when the triangular tongue 8 and the oblique tongue 6 move into the lock housing 1 at the same time, since the stroke of the oblique tongue 6 is greater than the stroke of the triangular tongue 8, the clutch paddle 9 and the oblique tongue plate 5 are gradually separated, and the clutch plate 11 does not move during this process; when the oblique tongue 6 is aligned with the corresponding square hole on the door frame, the oblique tongue 6 pops out and is inserted into the square hole of the door frame under the action of the tension spring 103, and there is no hole at the corresponding position of the triangular tongue 8 on the door frame, so the triangular tongue 8 is always blocked by the door frame when the door is closed. The latch 6 is held in the retracted position; during the rebound of the latch bolt 6, the second protrusion 104 of the latch bolt plate 5 gradually contacts the first protrusion 105 of the clutch paddle 9 and drives the clutch paddle 9 to rotate counterclockwise, and the first protrusion 105 of the clutch paddle 9 is gradually moved to contact the side of the latch bolt plate 5. At this time, when the latch bolt 6 continues to pop out, the first protrusion 105 of the clutch paddle 9 will continue to slide along the side without continuing to rotate, that is, the clutch paddle 9 reaches the maximum rotation position; during this process, the first bent portion 106 of the clutch paddle 9 will contact the second bent portion 107 of the clutch plate 11 and gradually push the clutch plate 11 to move upward. When the clutch paddle 9 reaches the maximum rotation position, the clutch plate 11 also reaches the maximum position, and the latch bolt 6 continues to pop out and reaches the maximum position; at the same time, the pressing portion 12 at one end of the clutch plate 11 is separated from the reed of the micro switch, and the micro switch is turned into a power-off state; at this time, the electronic system receives a power-off signal and gives a door lock signal, and the locking operation can be implemented at this time.

[0040] Specifically, the anti-lock mechanism includes an anti-lock tongue plate 13 which is laterally slidably arranged in the lock housing 1 and an anti-lock tongue 14 which is arranged at one end of the anti-lock tongue plate 13. An anti-locking block 15 which can move the anti-lock tongue plate 13 so that the anti-lock tongue 14 extends out of or retracts into the lock housing 1 is rotatably installed in the lock housing 1. When the anti-locking block 15 rotates counterclockwise, it will move the anti-lock tongue plate 13 to move the anti-lock tongue 14 out of the lock, and when the anti-locking block 15 rotates clockwise, it will move the anti-lock tongue plate 13 to move the anti-lock tongue 14 into the lock.

[0041] Specifically, the escape mechanism 500 includes an escape pull rod 16 vertically slidably disposed in the lock housing 1. An escape transmission mechanism 800 is connected between the anti-lock block 15 and the escape pull rod 16. The escape transmission mechanism 800 can drive the anti-lock block 15 to swing through the movement of the escape pull rod 16. The escape transmission mechanism 800 includes a straight slot 21 provided at the lower end of the escape pull rod 16. An escape swing arm 22 is rotatably installed in the lock housing 1. A fixing column 23 is provided at the upper end of the escape swing arm 22. The fixing column 23 is movably disposed in the straight slot 21. An escape link 24 is hinged to the lower end of the escape swing arm 22. One end of the escape link 24 is hinged to the anti-lock block 15. During operation, the escape pull rod 16 moves, driving the escape swing arm 22 to swing. The swinging of the escape swing arm 22 will cause the escape link 2 to move, and further cause the head of the anti-lock block 15 to swing, pushing the anti-lock tongue plate 13 into the lock body.

[0042] Specifically, the top and bottom hook mechanism 600 includes top and bottom hooks 17 symmetrically arranged in the lock housing 1. The main lock tongue plate 3 moves into the lock housing 1, thereby driving the two top and bottom hooks 17 to move into the lock housing 1. The top and bottom hook mechanism 600 is a prior art.

[0043] Specifically, the unlocking mechanism 700 can drive the main lock tongue plate 3 and the escape pull rod 16 to move simultaneously.

[0044] A central shaft 31 is provided in the lock housing 1. An opening arm 32 is rotatably installed on the central shaft 31. A first sector gear 33 and a guiding convex column 34 are respectively provided on the opening arm 32. A first oblique chute 35 is provided on the main lock tongue plate 3. The guiding convex column 34 is movably disposed in the first oblique chute 35.

[0045] The unlocking mechanism 700 of the present invention comprises a first motor 41 arranged in a lock housing 1, a motor gear 42 is arranged on the motor shaft of the first motor 41, a clutch shaft 43 is inserted in the lock housing 1, a driven gear 44 and a transmission gear 45 are rotatably mounted on the clutch shaft 43, the driven gear 44 can mesh with the motor gear 42, a cylinder 46 is arranged at the lower end of the driven gear 44, the cylinder 46 is sleeved outside the clutch shaft 43, a clutch sleeve 47 that can move up and down is arranged in the cylinder 46, a V-shaped notch 48 is symmetrically arranged at the lower end of the clutch sleeve 47, a wedge-shaped boss 49 that can cooperate with the V-shaped notch 48 is symmetrically arranged at the upper end of the transmission gear 45, and a step plate is arranged on the clutch shaft 43 inside the cylinder 46. A first spring 401 is connected between the step plate and the clutch sleeve 47 to keep the V-shaped notch 48 and the wedge-shaped boss 49 engaged. A rotating plate 402 is rotatably installed in the lock housing 1, and a second sector tooth 403 and a third sector tooth 404 are respectively provided on the rotating plate 402. The second sector tooth 403 can mesh with the transmission gear 45, and the third sector tooth 404 can mesh with the first sector tooth 33. An escape paddle 405 is rotatably installed on the central shaft 31, and one end of the escape paddle 405 can move the escape pull rod 16, and the opening arm 32 can swing the escape paddle 405. The locking process of the square tongue 4: the lock is in the open state, and the door closing operation is performed at this time. When the door body completely enters the door frame, the cross tongue mechanism 2 00 will give a door closing signal, and after receiving this signal, the electronic system will give a power-on signal to the first motor 41, the first motor 41 starts to start, the motor gear 42 rotates and drives the driven gear 44 to rotate; under normal circumstances, the resistance applied by the main lock mechanism 100 to the transmission gear 45 is not enough to overcome the pressure of the first spring 401 on the clutch sleeve 47, the clutch sleeve 47 and the wedge-shaped structure of the transmission gear 45 are buckled together, and the two are combined together and will not disengage, so that the transmission gear 45 and the driven gear 44 rotate synchronously, the transmission gear 45 is meshed with the second sector teeth 403 to drive the rotating plate 402 to rotate, the third sector teeth 404 of the rotating plate 402 are meshed with the first sector teeth 33, thereby driving the opening arm 32 to rotate, and the opening arm 32 drives the guide boss 34 to swing , and then through the setting of the first oblique sliding groove 35, the main lock bolt plate 3 drives the square bolt 4 to extend out of the lock. When the main lock bolt plate 3 reaches the maximum position, that is, the locked state, the main lock mechanism 100 gives a locking signal. After receiving this signal, the electronic system gives a power-off signal to the first motor 41, and the first motor 41 stops and remains in the power-off state, completing the locking process; when the resistance applied by the main lock mechanism 100 to the transmission gear 45 is greater than the pressure of the first spring 401 on the clutch sleeve 47, the clutch sleeve 47 will move up along the inclined surface until it is completely separated from the wedge-shaped structure of the transmission gear 45. At this time, the clutch sleeve 47 and the driven gear 44 can rotate freely together, and the first motor 41 that drives them to rotate is in an idling state, thereby preventing the motor from being overloaded and burned, and playing a protective function;When the first motor 41 idles for a certain number of circles, it will still stop. At this time, the clutch sleeve 47 and the transmission gear 45 are still in a disengaged state, and the transmission gear 45 also maintains its original state without any external action; when the external obstacle is removed and the unlocking or locking action is performed again, the first motor 41 is powered on again and continues to rotate (i.e., both forward and reverse rotations are possible), and the clutch sleeve 47 rotates until its V-shaped notch 48 is aligned with the wedge-shaped boss 49 of the transmission gear 45, and then automatically bounces into the transmission gear 45 under the pressure of the spring, the wedge-shaped structure is engaged, the clutch sleeve 47 is connected to the transmission gear 45 and rotates synchronously, and normal function is restored. The opening process of the square tongue 4: This process has the same action principle as the locking process, but the rotation direction is opposite. The difference is that during the opening process, if the anti-locking mechanism and the escape mechanism 500 are in the locked state, the opening arm 32 will turn the escape paddle 405 to rotate, thereby driving the escape mechanism 500 and the anti-locking mechanism to move. When the square tongue 4 reaches the open state, the anti-locking mechanism also reaches the open state; this unlocking mechanism 700 is a fully automatic opening type. ;

[0046] The lock housing 1 of the present invention also includes a handle fixing assembly 51 and a clutch driving assembly 52. ​​The handle fixing assembly 51 includes a mounting sleeve 53, a handle paddle 54 and an inner handle paddle 55 arranged in sequence in the lock housing 1. The mounting sleeve 53, the handle paddle 54 and the inner handle paddle 55 can rotate relative to each other. A square boss 56 is provided on one side of the inner handle paddle 55, and a fan-shaped notch 57 is provided on the handle paddle 54. The square boss 56 is swingably arranged in the fan-shaped notch 57. A vertical slide groove 58 is provided on the mounting sleeve 53. A clutch pin 59 is slidably provided in the vertical slide groove 58. The upper end of the clutch pin 59 extends to the outside of the mounting sleeve 53. A second spring 501 is connected between the clutch pin 59 and the vertical slide groove 58, which can keep the clutch pin 59 facing outward. A slot 502 is provided on the handle paddle 54, and the lower end of the clutch pin 59 can extend into the slot 502. The clutch drive assembly 52 can drive the clutch pin 59 to extend into the slot 502. First square holes 503 for installing handles are provided at both ends of the mounting sleeve 53, and a second square hole 504 is provided on the inner handle paddle 55. The first square hole 503 is larger than the second square hole 504. In this way, no matter which end is located inside or outside the door, the size is the same, that is, the square core size of the inner and outer handles inserted therein does not need to be changed, thereby achieving the purpose of no need for reversing.

[0047] The unlocking mechanism 700 of the present invention includes a handle fixing assembly 51 and a clutch driving assembly 52. ​​The handle fixing assembly 51 is arranged on the upper side of the main lock tongue plate 3 and the outer end of the clutch pin 59 is extended upward. The clutch driving assembly 52 includes a second motor 61 arranged in the lock housing 1. A first arc-shaped push plate 62 capable of linear movement is provided on the rotating shaft of the second motor 61. The arc surface of the first arc-shaped push plate 62 contacts the outer end of the clutch pin 59 and can drive the clutch pin 59 along the vertical slide groove. 58 moves, a first V-shaped paddle 63 is rotatably mounted on the central shaft 31, one end of the first V-shaped paddle 63 can cooperate with the inner handle paddle 55, and the other end of the first V-shaped paddle 63 can move the escape pull rod 16. When the door is opened, no electronic function is required, and the inner handle is directly rotated in the unlocking direction. The square core on the inner handle is inserted into the second square hole 504 of the inner handle paddle 55, so the inner handle paddle 55 is directly driven to rotate. Due to the square boss on the inner handle paddle 55 The fourth sector tooth 505 of the handle paddle 54 is meshed with the first sector tooth 33 of the opening arm 32, thereby driving the opening arm 32 to rotate, and the opening arm 32 drives the main lock mechanism 100 to retract into the lock to realize the opening function; when the door is opened, if the anti-locking mechanism is also in the locked state at this time, when the inner handle paddle 55 rotates, the first V-shaped paddle 63 will be driven to rotate, and the escape mechanism 500 will be released. The linkage drives the anti-locking mechanism to retract into the lock. When the inner handle is rotated to the maximum position and the lock is in the open state, the anti-locking mechanism also reaches the open state; this is the one-way escape function; if the main lock is in the locked state and the anti-locking mechanism is in the open state, since the first V-shaped paddle 63 and the inner handle paddle 55 are separated at this time, when the inner handle is rotated, the inner handle paddle 55 cannot reach the first V-shaped paddle 63, so the first V-shaped paddle 63 does not move, and the escape mechanism 500 and the anti-locking mechanism both remain in the open state.

[0048] The process of opening the door from outside: when the lock is in the locked state, the identity of the door opener must be authenticated by the electronic system when the door is opened from outside. If the authentication fails, the electronic system will not be activated, the second motor 61 will not operate, and the clutch mechanism will be in the open state, that is, the clutch pin 59 will be out of the slot 502, and the outer handle will be in an idling state. At this time, when the outer handle is turned, the mounting sleeve 53 linked to it will idle, and the lock will not be opened. If the authentication passes, the electronic system will be activated, and a power-on signal will be given to the second motor 61, and the second motor 61 will start to rotate. At this time, the second motor 61 will be turned on and the second motor 61 will start to rotate. The second motor 61 drives the first arc-shaped push plate 62 to move forward, and the first arc-shaped push plate 62 pushes the clutch pin 59 to move inside the slot 502, and is inserted into the slot 502 to realize the connection between the inner mounting sleeve 53 and the handle paddle 54, that is, the clutch mechanism is closed. At this time, the outer handle is rotated in the opening direction, and the mounting sleeve 53 drives the handle paddle 54 to rotate through the clutch pin 59. The fourth sector tooth 505 of the handle paddle 54 is meshed with the first sector tooth 33 of the opening arm 32, driving the main lock mechanism 100 to move into the lock to realize the opening function. After the opening process is completed, the electronic system receives the opening signal of the square tongue 4, the second motor 61 reverses, drives the first arc-shaped push plate 62 to retract, and the clutch pin 59 pops out under the elastic force of the second spring 501, and disengages from the handle paddle 54, that is, the clutch mechanism is opened, and the whole lock returns to the open state; during this process, the inner handle paddle 55 is motionless, so the escape mechanism cannot be driven when the outer handle opens the door, and it does not have the function of opening the anti-locking mechanism, which is a one-way escape function.

[0049] Locking process: When the lock is in the open state, the action processes of the two methods of locking the door inside and outside are basically the same. Both methods involve rotating the handle in the opposite direction to drive the internal mechanism to move in the opposite direction of the opening process described above, until the main lock tongue extends to the maximum position, completing the locking process. This process does not require electronic functions. This unlocking mechanism 700 is an upper handle opening method.

[0050] The unlocking mechanism 700 described in the present invention includes a handle fixing component 51 and a clutch driving component 52. The handle fixing component 51 is arranged on the lower side of the main lock tongue plate 3 and the outer end of the clutch pin 59 is extended downward. The clutch driving component 52 includes a third motor 71 arranged in the lock housing 1. A second arc-shaped push plate 72 that can move linearly is provided on the rotating shaft of the third motor 71. The arc-shaped surface of the second arc-shaped push plate 72 contacts the outer end of the clutch pin 59 and can drive the clutch pin 59 to move along the vertical slide groove 58. A second V-shaped paddle 73 is rotatably installed on the central shaft 31. One end of the second V-shaped paddle 73 can cooperate with the inner handle paddle 55, and the other end of the second V-shaped paddle 73 can drive the escape pull rod 16 to move. The principle is the same as above. This unlocking mechanism 700 is a lower handle opening method.

[0051] In the present invention, a lock core assembly 81 is rotatably installed in the lock housing 1. A lock core dial 82 is provided on the lock core assembly 81. A key push plate 83 is horizontally slidably installed in the lock housing 1. The lock core dial 82 can move the key push plate 83 horizontally. A cylindrical boss 84 is provided on the key push plate 83. A second inclined chute 85 is provided on the opening arm 32. The cylindrical boss 84 is movably arranged in the second inclined chute 85. The lock core assembly 81 includes a true plug lock core and a false plug lock core. During operation, the rotation of the lock core assembly 81 drives the lock core dial 82 to swing, thereby being able to move the key push plate 83 horizontally.

[0052] The present invention further includes a self - elastic mechanism 900. The self - elastic mechanism 900 includes a tension spring 91 and a damper 92. One end of the tension spring 91 is fixedly connected to one side of the side panel 2, and the other end of the tension spring 91 is fixedly connected to the main lock tongue plate 3. One end of the damper 92 is fixedly connected to the main lock tongue plate 3, and the other end of the damper 92 is fixedly connected to the side of the lock housing 1 away from the side panel 2. When the tension spring 91 is not under load, one end of the square tongue 4 extends out of the side panel 2. The tension spring 91 is arranged at the movement center of the two square tongues 4 and directly pulls the main lock tongue plate 3. Therefore, the two square tongues 4 are more evenly stressed, move more smoothly, and the loss of various forces is minimized. Thus, the tension of the tension spring 91 can be reduced to the minimum, which greatly reduces the opening force of the lock and makes the use experience better. Due to the characteristics of the damper 92 itself, a constant resistance is continuously applied to the main lock tongue plate 3, which buffers the pop - out process of the square tongue 4, greatly reducing the pop - out speed of the square tongue 4 to a slow pop - out. In this way, the impact force and impact sound on other parts are greatly reduced, playing a role in reducing impact and noise. The damping rod of the damper 92 has no resistance during the retraction process. Therefore, during the opening process, only the tension of the tension spring 91 needs to be overcome without the resistance of the damper 92, so that the opening force of the lock does not increase much.

[0053] As described above, changes and additions or deletions of some components will give rise to various types of lock bodies. Classified by the degree of automation of unlocking and locking, they can be divided into two categories: fully automatic locks and semi - automatic locks; classified by the setting of the handle, all lock bodies can be divided into three categories: handle - less locks (fully automatic locks), upper - handle locks, and lower - handle locks; classified by the structural form of the outer panel, they can be divided into two categories: integral locks and split locks; classified by the type of lock core, they can be divided into two categories: true plug core locks and false plug core locks; classified by the automatic locking method, they can be divided into two categories: self - elastic lock bodies and non - self - elastic lock bodies, etc.

[0054] Therefore, the lock body of the present invention can be configured as follows: 1. A true-insert lock core split-type fully automatic lock body; 2. A true-insert lock core split-type self-elastic fully automatic lock body; 3. A false-insert lock core split-type fully automatic lock body; 4. A false-insert lock core split-type self-elastic fully automatic lock body; 5. A true-insert lock core integral fully automatic lock body; 6. A true-insert lock core integral self-elastic fully automatic lock body; 7. A false-insert lock core integral fully automatic lock body; 8. A false-insert lock core integral self-elastic fully automatic lock body; 9. A true-insert lock core split-type upper handle semi-automatic lock body; 10. A true-insert lock core split-type upper handle self-elastic semi-automatic lock body; 11. A false-insert lock core split-type upper handle semi-automatic lock body; 12. A false-insert lock core split-type upper handle self-elastic semi-automatic lock body; 13. A true-insert lock core integral upper handle semi-automatic lock body; 14. A true-insert lock core integral upper handle self-elastic semi-automatic lock body; 15. A false-insert lock core integral upper handle semi-automatic lock body; 16. A false-insert lock core integral upper handle self-elastic semi-automatic lock body; 17. A split-type lower handle semi-automatic lock body; 18. A split-type lower handle self-elastic semi-automatic lock body; 19. An integral lower handle semi-automatic lock body; 20. An integral lower handle self-elastic semi-automatic lock body;

[0055] For the classification according to the handle setting, the fully automatic lock does not require a handle, that is, there is no handle unlocking mechanism. Compared with the upper handle semi-automatic lock, it adopts a fully automatic unlocking mechanism. At the same time, the motor assembly is a fully automatic motor assembly, and other mechanism parts remain unchanged; the upper handle semi-automatic lock places the handle unlocking mechanism on the upper part of the lock. Compared with the fully automatic lock, the handle unlocking mechanism replaces the fully automatic unlocking mechanism. At the same time, the motor assembly is a semi-automatic motor assembly, and the others remain unchanged; the lower handle semi-automatic lock places the handle unlocking mechanism on the lower part of the lock. Compared with the upper handle semi-automatic lock, its handle unlocking mechanism is the same, only the installation direction is different. At the same time, the key unlocking mechanism is removed, and the others remain unchanged;

[0056] For the classification according to the structural form of the outer panel, the difference between the overall and split configurations of each type of lock body lies only in the different openings of the lock shell and the cover plate. The lock shell and the cover plate of the split lock are respectively provided with four round holes at the corresponding positions for the function of the panel positioning column, while the integral lock does not have these four holes, and the others remain unchanged;

[0057] For the classification according to the lock core type, for the fully automatic lock and the upper handle semi-automatic lock, the difference is only in the installation of the true-insert core assembly or the false-insert core assembly at the lock core hole position, and the others remain unchanged. The lower handle lock does not require a key to open and does not install an insert core structure; for the true-insert core lock body, since the lock core is installed on-site during door installation, only a lock core installation hole is reserved on the lock body, while the false-insert core lock body needs to install the false-insert core assembly in the lock body;

[0058] For the classification according to the automatic locking method, the difference between the self-elastic and non-self-elastic configurations of each type of lock body lies only in whether the self-elastic mechanism is installed, and other mechanisms remain unchanged.
