The second transmission member 106 is slidably arranged on the support member 101, and is driven by the mechanical power of the mechanical lock core 200 of the lock body to drive the power coupling member 104 to slide along the transmission shaft 103; the third transmission member 108 can cooperate with the power coupling member 104 and the mechanical lock core 200 of the lock body to drive the lock tongue assembly 400 of the lock body to lock or unlock; the power coupling member 104 is slidably sleeved on the transmission shaft 103, and is driven by the second transmission member 106 to switch between the coupling state and the uncoupling state with the first transmission member 102. When the power coupling member 104 is in the coupling state, the power coupling member 104 is in transmission connection with the first transmission member 102; when the power coupling member 104 is in the uncoupling state, the power coupling member 104 is separated from the first transmission member 102.

[0047] When in use, when the motor module of the lock body outputs electric power, and the electric power is in the unlocking direction, when the first transmission member 102 receives the electric power, the power coupling member 104 is in the coupling state; when the electric power direction is in the unlocking direction, the third transmission member 108 drives the bolt assembly 400 to unlock under the action of the first transmission member 102; when the electric power direction is in the locking direction, the third transmission member 108 drives the bolt assembly 400 to lock under the action of the first transmission member 102; when the mechanical lock core 200 of the lock body outputs mechanical power, and the mechanical power is in the unlocking direction, the second transmission member 106 drives the power coupling member 104 to switch from the coupling state to the uncoupling state; the third transmission member 108 drives the bolt assembly 400 to unlock under the action of the mechanical lock core; when the mechanical power direction is in the locking direction, the third transmission member 108 drives the bolt assembly 400 to lock. Therefore, in the power switching structure 100 of the present invention, when the motor module 300 fails, the mechanical lock core 200 can still continue to unlock and lock. This can ensure safety performance and bring convenience to life.

[0048] The second transmission member 106 and the power coupling member 104 cooperate with each other to realize the switching of the power coupling member between the coupled state and the uncoupled state, wherein the second transmission member 106 may be provided with a first elastic member 107, and the power coupling member 104 may be provided with a second elastic member 105 to cooperate in the switching. Of course, the switching may also be performed by setting other methods.

[0049] When the first elastic member 107 and the second elastic member 105 are arranged, a power switching structure in some embodiments of the present invention includes a support member 101, a transmission shaft 103, a first transmission member 102, a second transmission member 106, a third transmission member 108, a power coupling member 104, a first elastic member 1057 and a second elastic member 107105, wherein the support member 101 is used to support the arrangement of the transmission shaft 103, the first transmission member 102, the second transmission member 106, the third transmission member 108, the first elastic member 105, the first elastic member 107 and the second elastic member 107105; the first transmission member 102 can receive the electric power of the motor module 300; the transmission shaft 103 is arranged on the support member 101, and the transmission shaft 103 is arranged on the A positioning member 1031 is fixed; the power coupling member 104 is configured with a coupled state and an uncoupled state, and the power coupling member 104 is slidably sleeved on the transmission shaft 103; when the power coupling member 104 is in the coupled state, the power coupling member 104 is transmission-connected with the first transmission member 102; when the power coupling member 104 is in the uncoupled state, the power coupling member 104 is transmission-separated from the first transmission member 102; the first elastic member 105 and the first elastic member 107 are between the positioning member 1031 and the power coupling member 104, and the first elastic member 105 and the first elastic member 107 can keep the power coupling member 104 in the coupled state; the second transmission member 106 can receive the mechanical power of the mechanical lock cylinder 200, and the second transmission member 106 is slidably arranged on the support The support member 101 is slidably matched with the power coupling member 104, and the second transmission member 106 can push the power coupling member 104 to switch from a coupled state to a non-coupled state; the second elastic member 107 and the second elastic member 105 are between the support member 101 and the second transmission member 106, and the second elastic member 107 and the second elastic member 105 can prevent the second transmission member 106 from pushing the power coupling member 104 to switch from a coupled state to a non-coupled state, and drive the second transmission member 106 to reset when the mechanical power is withdrawn; and the third transmission member 108 can be connected to the lock tongue assembly 400, and the third transmission member 108 can cooperate with the first transmission member 102 and the second transmission member 106 in transmission; when the first transmission member 102 receives electric power, the power coupling member 104 In a coupled state; when the direction of the electric power is in an unlocking direction, the third transmission member 108 drives the lock tongue assembly 400 to unlock under the action of the first transmission member 102; when the direction of the electric power is in a locking direction, the third transmission member 108 drives the lock tongue assembly 400 to lock under the action of the first transmission member 102; when the second transmission member 106 receives mechanical power, the second transmission member 106 pushes the power coupling member 104 to switch from a coupled state to a non-coupled state; when the direction of the mechanical power is in an unlocking direction, the third transmission member 108 drives the lock tongue assembly 400 to unlock under the action of the second transmission member 106; when the direction of the mechanical power is in a locking direction, the second transmission member 106, under the action of the second first elastic member 107, causes the third transmission member 108 to drive the lock tongue assembly 400 to lock.

[0050] When in use, when the first transmission member 102 receives electric power, the power coupling member 104 is in a coupled state; when the direction of the electric power is in an unlocking direction, the third transmission member 108 drives the bolt assembly 400 to unlock under the action of the first transmission member 102; when the direction of the electric power is in a locking direction, the third transmission member 108 drives the bolt assembly 400 to lock under the action of the first transmission member 102; when the second transmission member 106 receives mechanical power, the second transmission member 106 pushes the power coupling member 104 to switch from a coupled state to a non-coupled state; when the direction of the mechanical power is in an unlocking direction, the third transmission member 108 drives the bolt assembly 400 to unlock under the action of the second transmission member 106; when the direction of the mechanical power is in a locking direction, the second transmission member 106 drives the bolt assembly 400 to lock under the action of the second elastic member 105. Therefore, in the power switching structure 100 of the present invention, when the motor module fails, the mechanical lock core 200 can still continue to unlock and lock. Thereby, safety performance can be guaranteed and convenience can be brought to life.

[0051] It should be noted that the electric power is the power output by the motor module 300, which is divided into an unlocking direction and a locking direction according to needs; the mechanical power is the power output by the mechanical lock core 200, which is divided into an unlocking direction and a locking direction according to needs.

[0052] The function of the support member 101 is to support the arrangement of the transmission shaft 103, the first transmission member 102, the second transmission member 106, the third transmission member 108, the power coupling member 104, the first elastic member 107 and the second elastic member 105. The support member 101 can be the housing of the lock body, or can be arranged separately and installed when necessary.

[0053] The function of the first transmission member 102 is to receive the electric power output by the motor module 300. When the direction of the electric power is the unlocking direction, the first transmission member 102 rotates in the unlocking direction. When the direction of the electric power is the locking direction, the first transmission member 102 rotates in the locking direction. The rotation of the first transmission member 102 is transmitted to the transmission shaft 103 through the power coupling member 104, and then transmitted to the third transmission member 108 by the transmission shaft 103. When the power coupling member 104 is in a coupled state, the first transmission member 102 and the power coupling member 104 can be connected in transmission, and the two can transmit torque; when the power coupling member 104 is in an uncoupled state, the second power and the power coupling member 104 are separated in transmission, and the two cannot transmit torque.

[0054] The second transmission member 106 is used to receive the mechanical power output by the mechanical lock core 200. When the direction of the mechanical power is the unlocking direction, the second transmission member 106 moves in the unlocking direction. When the direction of the mechanical power is the locking direction, the second transmission member 106 moves in the locking direction. The movement of the second transmission member 106 can be directly transmitted to the third transmission member 108, and can also be indirectly transmitted to the third transmission member 108.

[0055] The second transmission member 106 is slidably arranged on the support member 101 through a fastener. In some embodiments, a slide groove 1061 slidably matched with the fastener is arranged on the second transmission member 106, and the fastener is fixed on the support member 101. Alternatively, the second transmission member 106 is provided with a fastener, and a slide groove 1061 slidably matched with the fastener is arranged on the support member 101. Of course, the second transmission member 106 can also be slidably arranged on the support member 101 in other ways, as long as the second transmission member 106 can be slidably arranged on the support member 101, it is within the protection scope of the present invention.

[0056] The second transmission member 106 can transmit the mechanical power output by the mechanical lock core 200 to the third transmission member 108, and the second transmission member 106 can also switch the coupling state of the power coupling member 104. In some embodiments of the present invention, the end surface of the second transmission member 106 close to the power coupling member 104 is provided with a first wedge surface 1062, and the end surface of the power coupling member 104 close to the second transmission member 106 is provided with a second wedge surface. When the second transmission member 106 is under the mechanical power of the mechanical lock core 200, the first wedge surface 1062 and the second wedge surface cooperate and push the power coupling member 104 to move in a direction away from the first transmission member 102, so that the power coupling member 104 is switched from the coupling state to the uncoupling state.

[0057] The portion of the second transmission member 106 where the first wedge surface 1062 is provided is an integral structure or a split structure with the second transmission member 106 . When it is a split structure, the portion can be connected to the second transmission member 106 in an inseparable or detachable manner.

[0058] The part of the power coupling member 104 provided with the second wedge-shaped surface is an integral structure or a split structure with the power coupling member 104. When it is a split structure, the part of the power coupling member 104 provided with the second wedge-shaped surface is a push block 1041, and the push block 1041 is detachably connected to the power coupling member 104 or non-detachably connected.

[0059] The coupling between the power coupling member 104 and the first transmission member 102 is achieved by setting a coupling part 1042, wherein at least two coupling parts 1042 are set on the end surface of the power coupling member 104 close to the first transmission member 102, and at least two arc-shaped runway grooves 1021 are set on the end surface of the first transmission member 102 close to the power coupling member 104, and the coupling state is achieved by the sliding cooperation between the two coupling parts 1042 and the corresponding arc-shaped runway grooves 1021.

[0060] When the power coupling 104 is in a coupled state, the first transmission member 102 rotates under the action of the electric force in the unlocking direction. Since the arc-shaped runway groove 1021 slides with the coupling part 1042, when the coupling part 1042 abuts against one end of the arc-shaped runway groove 1021, the first transmission member 102 can drive the coupling part 1042 to rotate by a preset angle; the first transmission member 102 rotates under the action of the electric force in the locking direction. Since the arc-shaped runway groove 1021 slides with the coupling part 1042, when the coupling part 1042 abuts against the other end of the arc-shaped runway groove 1021, the first transmission member 102 can drive the coupling part 1042 to rotate by a preset angle.

[0061] The power coupling 104 is directly sleeved on the transmission shaft 103, or matched with the transmission shaft 103 through a sleeve.

[0062] The function of the transmission shaft 103 is to support the third transmission member 108, the second transmission member 106, the power coupling member 104 and the first transmission member 102. The transmission shaft 103 is rotatably arranged on the support member 101, or the transmission shaft 103 is directly fixed on the support member 101. The switching between the coupling state and the non-coupling state between the power coupling member 104 and the first transmission member 102 can be achieved through the transmission shaft 103, and can also be achieved by direct action. When the transmission shaft 103 is rotatably arranged on the support member 101, the first transmission member 102 and the second transmission member 106 are rotatably arranged on the transmission shaft 103, the power coupling member 104 and the transmission shaft 103 can transmit a rotation pair, and the third transmission member 108 is fixed on the transmission shaft 103. Or when the transmission shaft is directly fixed on the support member 101, the first transmission member 102, the second transmission member 106, the power coupling member 104 and the third transmission member 108 can be rotatably arranged on the transmission shaft 103, and the power coupling member and the third transmission member 108 can transmit the rotation pair.

[0063] The third transmission member 108 acts directly on the bolt assembly 400 to unlock and lock the bolt assembly 400. The third transmission member 108 is fixed on the transmission shaft 103, and the third transmission member 108 can rotate with the transmission shaft 103. When the transmission shaft 103 rotates under the action of the first transmission member 102, the third transmission member 108 fixed on the transmission shaft 103 can also rotate with the transmission shaft 103. At this time, the transmission shaft 103 is rotatably arranged on the support member 101.

[0064] Alternatively, in some embodiments, the third transmission member 108 may be coupled to the power coupling member 104. When the power coupling member 104 is in a coupled state, the power coupling member 104 and the third transmission member 108 are transmission-connected; when the power coupling member 104 is in an uncoupled state, the power coupling member 104 and the third transmission member 108 are transmission-decoupled.

[0065] There are many structures that can achieve the coupling between the third transmission member 108 and the power coupling member 104. For example, the matching relationship between the power coupling member 104 and the first transmission member 102 can be referred to. In some embodiments of the present invention, the third transmission member 108 is provided with at least two notches coupled with the power coupling member 104.

[0066] When the power coupling 104 is in a coupled state, the coupling portion 1042 of the power coupling 104 passes through the notch and cooperates with the arc runway groove 1021 on the first transmission member 102. When the power coupling 104 is in an uncoupled state, the coupling portion 1042 of the power coupling 104 is separated from both the notch and the arc runway groove 1021.

[0067] In some embodiments of the present invention, the first transmission member 102 is a gear, a pulley or a sprocket. Preferably, a gear is selected, and correspondingly, the output end of the motor module 300 is provided with a gear matched with the first transmission member 102.

[0068] The function of the positioning member 1031 is to provide stable support for the second elastic member 105, wherein the positioning member 1031 is detachably connected or non-detachably connected to the transmission shaft 103. In the present invention, the positioning member 1031 and the transmission shaft 103 are threadedly matched, and the elastic force of the second elastic member 105 can be adjusted by rotation.

[0069] According to the above description, the second transmission member 106 and the third transmission member 108 can be directly connected by transmission, or can be connected by setting other components. In some embodiments of the present invention, the second transmission member 106 and the third transmission member 108 are connected by transmission through the fourth transmission member 109. The fourth transmission member 109 is in transmission cooperation with the second transmission member 106 and the third transmission member 108; the fourth transmission member 109 can drive the third transmission member 108 to rotate so that the bolt assembly 400 is unlocked / locked.

[0070] The fourth transmission member 109 is provided with a guide portion 1091, and the second transmission member 106 is provided with a guide groove 1063 that is slidably matched with the guide portion 1091. When the second transmission member 106 receives mechanical power, the second transmission member 106 pushes the power coupling member 104 to switch from a coupled state to a non-coupled state; when the direction of the mechanical power is the unlocking direction, the mechanical lock core 200 pushes the second transmission member 106 to move to the right as shown in the figure, and the fourth transmission member 109 rotates clockwise under the limiting effect of the guide portion 1091 and the guide groove 1063, and the fourth transmission member 109 drives the third transmission member 108 to rotate in a counterclockwise direction until the bolt assembly 400 is driven to unlock; when the direction of the mechanical power is the locking direction, the second transmission member 106 moves to the left under the action of the first elastic member 107, and the fourth transmission member 109 rotates counterclockwise under the limiting effect of the guide portion 1091 and the guide groove 1063, so that the third transmission member 108 drives the bolt assembly 400 to lock. Therefore, in the power switching structure 100 of the present invention, when the motor module fails, the mechanical lock core 200 can still continue to unlock and lock.

[0071] Alternatively, the fourth transmission member 109 is provided with a first toggle portion 1092 , and the second transmission member 106 is provided with a hook matched with the first toggle portion 1092 .

[0072] The fourth transmission member 109 and the third transmission member 108 are driven by a toggle transmission. Specifically, the fourth transmission member 109 and the third transmission member 108 are provided with a second toggle portion 1093 at the corresponding position, and the third transmission member 108 is provided with a notch matched with the second toggle portion 1093. Alternatively, the fourth transmission member 109 and the third transmission member 108 can also be driven by a gear. When the second transmission member 106 receives mechanical power, the second transmission member 106 pushes the power coupling member 104 to switch from the coupling state to the non-coupling state; when the direction of the mechanical power is the unlocking direction, the mechanical lock core 200 pushes the second transmission member 106 to move to the right as shown in the figure, and the fourth transmission member 109 rotates clockwise under the limiting effect of the guide portion 1091 and the guide groove 1063, and the fourth transmission member 109 drives the third transmission member 108 to rotate in the counterclockwise direction through gear matching until the lock tongue assembly 400 is unlocked; when the direction of the mechanical power is the locking direction, the second transmission member 106 moves to the left under the action of the first elastic member 107, and the fourth transmission member 109 rotates counterclockwise under the limiting effect of the guide portion 1091 and the guide groove 1063, so that the third transmission member 108 drives the lock tongue assembly 400 to lock. Therefore, in the power switching structure 100 of the present invention, when the motor module 300 fails, the mechanical lock core 200 can still continue to unlock and lock.

[0073] When the fourth transmission member 109 and the third transmission member 108 are driven by gears, the portion of the third transmission member 108 close to the third transmission member 108 is provided with a first tooth portion 1081, and the portion of the fourth transmission member 109 close to the third transmission member 108 is provided with a second tooth portion 1094, and the first tooth portion 1081 and the second tooth portion 1094 can mesh. The relative angle between the first tooth portion 1081 and the second tooth portion 1094 can be adjusted according to the angle required for transmission, and any angle that can achieve the unlocking action and the locking action can be understood as the angle to be protected by the present invention.

[0074] Example 1

[0075] The power switching structure 100 of the present invention includes a support member 101, a first transmission member 102, a second transmission member 106, a third transmission member 108, a fourth transmission member 109, a power coupling member 104, a first elastic member 107 and a second elastic member 105, wherein the fourth transmission member 109 and the third transmission member 108 are movably matched.

[0076] When the key is not inserted to rotate the mechanical lock cylinder 200 or the fourth transmission member 109 is not rotated mechanically, when the second transmission member 106 is located at the far left, the power coupling member 104 is affected by the vertical downward elastic force of the second elastic member 105, and the power coupling member 104 is located at the bottom. The second wedge surface of the power coupling member 104 and the first wedge surface 1062 above the second transmission member 106 are in physical contact, and the coupling part 1042 at the bottom of the power coupling member 104 is inserted into the two arc-shaped runway grooves 1021 of the first transmission member 102. The rotation of the first transmission member 102 can drive the power coupling member 104 to rotate through physical contact, and the motor module 300 can drive the lock tongue 402 to realize automatic locking and unlocking of the fully automatic lock body.

[0077] When the key is inserted to rotate the mechanical lock cylinder 200 or the fourth transmission member 109 is rotated mechanically, the second transmission member 106 can be pushed to move to the rightmost side, and the second wedge surface of the power coupling member 104 and the first wedge surface 1062 above the second transmission member 106 are in physical contact. The power coupling member 104 is affected by the second transmission member 106, and the power coupling member 104 is located at the top. The coupling part 1042 at the bottom of the power coupling member 104 is not inserted into the two arc-shaped runway grooves 1021 of the first transmission member 102. The rotation of the first transmission member 102 cannot drive the power coupling member 104 to rotate through physical contact, and the motor module 300 cannot drive the lock tongue 402 to achieve automatic locking and unlocking of the fully automatic lock body, realizing the separation of mechanical structure and motor power through internal mechanism. In this case, the door lock can be opened by key or mechanical method, and is not affected by power failure or motor failure after locking, which is caused by the mechanical structure being stuck by the motor.

[0078] Example 2

[0079] The power switching structure 100 of the present invention includes a support member 101, a first transmission member 102, a second transmission member 106, a third transmission member 108, a fourth transmission member 109, a power coupling member 104, a first elastic member 107 and a second elastic member 105, wherein the third transmission member 108 and the fourth transmission member 109 are gear-matched.

[0080] The fourth transmission member 109 contacts the lower right side of the second transmission member 106. The second transmission member 106 has discontinuous notches at both ends. When the fourth transmission member 109 rotates to the right, it can push the second transmission member 106 to move to the right. After the second transmission member 106 moves a certain distance, the fourth transmission member 109 disengages from the first notch of the second transmission member 106. At this time, the second transmission member 106 has moved to the far right to achieve electromechanical separation. A circular protrusion on the top of the fourth transmission member 109 is coaxial with a circular notch of the second transmission member 106. The fourth transmission member 109 can continue to rotate to the right while in physical contact with the second transmission member 106, and the lock tongue 402 of the lock body can be unlocked to achieve mechanical unlocking, while the second transmission member 106 is fixed in the original position and no longer moves.

[0081] The second tooth portion 1094 is assembled on the fourth transmission member 109, and the first tooth portion 1081 is assembled on the third transmission member 108. The second tooth portion 1094 is meshed with the first tooth portion 1081. When the fourth transmission member 109 rotates rightward, the second tooth portion 1094 can be driven to rotate clockwise and the first tooth portion 1081 can be driven to rotate counterclockwise to unlock the bolt assembly 400. When the fourth transmission member 109 rotates leftward, the second tooth portion 1094 can be driven to rotate counterclockwise and the first tooth portion 1081 can be driven to rotate clockwise to lock the bolt assembly 400.

[0082] In the second aspect, an embodiment of the present invention provides a lock body, including a mechanical lock core 200, a motor module 300 and a lock tongue assembly 400, and also includes a power switching structure 100 as any of the above items, wherein the first transmission member 102 of the power switching structure 100 can be transmission-connected to the motor module 300, the second transmission member 106 of the power switching structure 100 can be transmission-connected to the mechanical lock core 200, and the third transmission member 108 and the second transmission member 106 of the power switching structure 100 can be transmission-connected to the lock tongue assembly 400.

[0083] In some embodiments, the mechanical lock core 200 is provided with a lock core shift block, and the lock core shift block can be connected with the second transmission member 106 through an arc surface.

[0084] In some embodiments, the lock tongue assembly 400 includes a lock tongue pressure plate 401 and a lock tongue 402. The lock tongue 402 is arranged on the lock tongue pressure plate 401, and the lock tongue pressure plate 401 is provided with a avoidance groove 4011 and an unlocking groove 4012 of the transmission part on the third transmission member 108. When the transmission part of the third transmission member 108 slides in the first direction of the unlocking groove 4012, the lock tongue 402 is unlocked. When the transmission part of the third transmission member 108 slides in the second direction of the unlocking groove 4012, the lock tongue 402 is locked. The first direction and the second direction are opposite.

[0085] The motor module 300 transmits the power to the first transmission member 102 through the motor output gear. The first transmission member 102 has two arc-shaped runway grooves 1021. When the coupling part 1042 at the bottom of the power coupling member 104 is inserted into the two arc-shaped runway grooves 1021 of the first transmission member 102, the first transmission member 102 rotates and drives the power coupling member 104 to rotate through physical contact. The coupling part 1042 at the top of the power coupling member 104 is inserted into the semicircular notch on one side of the third transmission member 108. When the power coupling member 104 rotates, it can drive the third transmission member 108 to rotate. The front end of the third transmission member 108 has a downward cylindrical guide column inserted into the oblique groove corresponding to the lock tongue pressure plate 401. The rotation of the third transmission member 108 can drive the lock tongue assembly 400 to reciprocate in the vertical direction. The direction of movement is controlled by the right motor module 300 in forward and reverse directions.

[0086] The mechanical lock core 200 is a true mortise lock core fixed on the left side of the lock body by a screw. When the key is inserted and rotated, it can drive the lock core block to rotate and physically contact the second transmission member 106, which can push the second transmission member 106 to move to the right. After pushing the second transmission member 106 away, the lock core block continues to rotate left and right to lock and unlock the lock tongue 402 respectively.

[0087] In some embodiments, the lock body also includes a secondary tongue assembly 500. The top of the lock tongue assembly 400 has two cylindrical guide columns that are inserted into the circular holes on both sides of the middle connecting plate of the secondary tongue assembly 500. The reciprocating motion of the lock tongue assembly 400 in the vertical direction can drive the secondary tongue assembly 500 to reciprocate in the same direction.

[0088] Furthermore, it also includes an upper sky hook 700 and a lower sky hook 800. There are two cylindrical guide columns on both sides of the auxiliary tongue assembly 500, which are respectively inserted into the corresponding inclined grooves of the upper sky hook 700 and the lower sky hook 800. The auxiliary tongue assembly 500 reciprocates in the vertical direction to drive the upper sky hook 700 and the lower sky hook 800 to reciprocate to the left and right sides respectively.

[0089] In some embodiments, the lock body also includes a latch bolt assembly 600. The motor module 300 rotates to drive the first transmission member 102 to rotate. The counterclockwise rotation of the first transmission member 102 can push the latch bolt assembly 600 downward through the connecting rod under the fourth transmission member 109. When the first transmission member 102 rotates clockwise or counterclockwise, the latch bolt assembly 600 is not subject to the downward thrust of the connecting rod under the fourth transmission member 109, and moves upward back to its original position under the action of the spring inside the latch bolt assembly.

[0090] There are multiple switches on the PCB assembly of the lock body that contact the internal parts of the lock body, which can determine the extended or retracted position of the lock tongue 402. Through the above mechanical and software logic, the motor module 300 can control the movement of the inclined tongue assembly 600, the upper top and bottom hooks 700, the auxiliary tongue assembly 500, the lock tongue assembly 400, and the lower top and bottom hooks 800 to achieve automatic locking and unlocking of the fully automatic lock body.

[0091] The fourth transmission member 109 is fixed to the right side of the lock body. The cylindrical guide part 1091 at the bottom of the fourth transmission member 109 is inserted into the guide groove 1063 of the second transmission member 106. The fourth transmission member 109 rotates rightward to pull the second transmission member 106 to move rightward. After pushing the second transmission member 106 away, the fourth transmission member 109 continues to rotate rightward, and the oblique bolt assembly 600 can be moved downward by the connecting rod below to unlock the oblique bolt assembly 600. The cylindrical guide part 1091 facing downward on the left side of the fourth transmission member 109 can be used to move the third transmission member 108 counterclockwise to unlock the bolt assembly 400. When the key returns to the original position and the fourth transmission member 109 is not under force, under the action of the second elastic member 105, the second transmission member 106 is affected by the left pulling force and returns to the original position, and the oblique bolt assembly 600 moves upward and returns to the original position under the action of the internal spring. Through the above logic, it is possible to achieve locking and unlocking of the real mortise fully automatic lock body by key or mechanical means.

[0092] The lock body is also provided with a communication component, and the terminal device can control the operation of the motor module 300 through the communication component. The information exchange between the terminal device and the communication component is realized through the network and the server. The network is used to provide a medium for the communication link between the terminal device and the server. The network can include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0093] The user can use the terminal device to interact with the server through the network to receive or send messages, etc. Various client applications can be installed on the terminal device.
