[0004] The purpose of this application is to provide a multi-point detection lock body to solve at least one of the above technical problems.

[0005] In order to solve the above technical problems, the present application provides a multi-point detection lock body, including a shell, and an inclined tongue assembly, a main lock assembly, a spring tongue assembly, a handle drive mechanism and a lock core drive mechanism arranged in the shell;

[0006] The handle driving mechanism comprises a handle paddle and a latch bolt paddle, wherein the handle paddle is linked with the main lock assembly and the latch bolt paddle; the handle paddle is rotatably arranged on the housing and has a first limit position and a second limit position in its rotation stroke, when in the first limit position, the main lock assembly partially extends out of the housing to be in a locked state, and when in the second limit position, the main lock assembly is retracted into the housing to be in an unlocked state, and the latch bolt assembly is retracted into the housing to be in an unlocked state;

[0007] Also included are a first detection component, a second detection component and a third detection component disposed in the housing;

[0008] The first detection component is arranged on the rotation stroke of the handle paddle, the second detection component is located on the movement stroke of the spring tongue component, and the third detection component is located on the movement stroke of the inclined tongue component;

[0009] In the above implementation process, the present scheme respectively sets up three detection components for respectively detecting the opening and closing conditions of different positions; among them, the first detection component is arranged on the rotation stroke of the handle paddle, and the rotation position of the handle paddle is related to the position of the main lock component. Therefore, detecting the position rotation condition of the handle paddle by the first detection component can be equivalent to detecting the position condition of the main lock component, that is, whether the main lock component is in a locked state or an unlocked state; the second detection component is arranged on the moving stroke of the spring tongue component, and the spring tongue component can be used to detect whether the door body is closed in place. The relative positions of the spring tongue components that are closed and not closed are different from those of the second detection component, and thus the second detection component obtains different The third detection component is arranged on the moving path of the inclined tongue component, and when the inclined tongue component switches between the locked and unlocked states, the inclined tongue component and the third detection component switch between approaching and moving away from each other, and in this process they will also abut and then move away from each other, and in this action process the third detection component obtains different signals to detect whether the inclined tongue component has completed the locking. In this solution, three groups of detection components are used to detect multiple points of the lock body, so that the user can comprehensively monitor the specific closing status of the current door lock in actual use, effectively reduce safety risks, and improve safety of use.

[0010] Preferably, a PCB board is provided in the housing, and the first detection component, the second detection component and the third detection component are all provided on the PCB board;

[0011] In the above implementation process, this solution integrates the first detection component, the second detection component and the third detection component on the same PCB board, which can make it easier to simplify the structure without installing multiple PCB boards in multiple times. It is also more conducive to the integration of the structure, making the structure more compact.

[0015] In the above implementation process, when the door body is closed, the tongue body will abut against the door frame and then retract. When the tongue body retracts, it will drive the first fixed rod to retract. The retracted first fixed rod will abut against the second microswitch and further press the spring of the second microswitch to trigger the switch. The trigger switch can be a disconnect signal or a connection signal. It is understandable that, considering that the door body is in a closed state most of the time, the trigger switch can be set to a disconnect signal, which can save power consumption to a certain extent. After the door body is closed, the first elastic member is squeezed to store elastic potential energy. After the door body is opened, the first elastic member releases the elastic potential energy to cause the tongue body to pop out, and the first fixed rod moves away from the second microswitch to achieve signal connection.

[0016] Preferably, the oblique tongue assembly comprises an oblique tongue body, a second fixing rod, a sliding plate and a second elastic member;

After the external force is lost, the second elastic member releases the elastic potential energy, prompting the second fixed rod to reset and then prompting the inclined tongue body to reset; after the second fixed rod is reset, it approaches the third micro switch and triggers the switch by further triggering the spring sheet on the third micro switch; it is understandable that, considering that the inclined tongue body is in a pop-up state most of the time, the second fixed rod will press the spring sheet of the third micro switch when it pops up, and it can be set to be a signal disconnection state at this time, which can save energy to a certain extent; it is further understandable that by judging whether the signal of the third micro switch is in a disconnected state or a connected state in combination with the second detection component, the current state of the inclined tongue body can be further determined.

[0026] Preferably, the handle paddle is provided with an arc-shaped groove, the oblique tongue paddle is provided with a second paddle portion, and the second paddle portion extends into the arc-shaped groove;

[0027] It also includes a square shaft core suitable for passing through the handle paddle and the oblique tongue paddle.

[0029] One end of the lock core paddle abuts against the second toggle portion and is suitable for acting on the second toggle portion, so that the second toggle portion drives the handle paddle to switch from the first extreme position to the second extreme position;

[0030] A third toggle portion is provided on the handle paddle, and when the lock cylinder paddle rotates in a direction away from the first toggle portion, it is suitable for acting on the third toggle portion to switch the handle paddle from the second extreme position to the first extreme position;

[0031] In the above implementation process, the lock core drive assembly can cooperate with the lock core of the lock to drive the lock core drive assembly to move.

[0035] In the above implementation process, when the handle paddle rotates, it will approach or move away from the first microswitch. When it approaches, it will be mortgaged on the spring sheet of the first microswitch and trigger the switch, and when it moves away from the switch; in some embodiments, it can be understood that the fourth toggle part on the handle paddle triggers the first microswitch as a turn-on signal, at which time the main lock tongue extends; when the fourth toggle part on the handle paddle moves away from the first microswitch, the signal is disconnected, and the main lock tongue retracts into the shell.

[0055] In order to further understand the content, features and effects of the utility model of the present application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0056] Example

[0057] At present, electronic smart locks have been widely used in various scenarios, such as hotels, apartments, guesthouses, etc.; since most users in such scenarios are travelers, and travelers are not in the room most of the time, the security issue in the room is particularly important. When users enter and exit, sometimes they may encounter the problem of the door being half-open, and sometimes they may not observe carefully, and the half-open door is difficult to be discovered. At this time, outsiders can easily enter the room, which poses a certain security risk; in order to solve the above technical problems, this embodiment provides the following technical solutions:

When in the first limit position, the main lock assembly 40 partially extends out of the housing 10 to be in a locked state, and when in the second limit position, the main lock assembly 40 is retracted into the housing 10 to be in an unlocked state, and the latch bolt assembly 20 is retracted into the housing 10 to be in an unlocked state;

[0060] Furthermore, it also includes a first detection component 71, a second detection component 72 and a third detection component 73 disposed in the housing 10;

[0061] Specifically, the first detection component 71 is disposed on the rotational travel of the handle paddle 50 , the second detection component 72 is located on the moving travel of the spring tongue component 30 , and the third detection component 73 is located on the moving travel of the oblique tongue component 20 ;

[0062] In the above scheme, three detection components are respectively arranged in this scheme for detecting the opening and closing conditions of different positions respectively; wherein, the first detection component 71 is arranged on the rotation stroke of the handle paddle 50, and the rotation position of the handle paddle 50 is related to the position of the main lock component 40, so detecting the position rotation condition of the handle paddle 50 by the first detection component 71 can be equivalent to detecting the position condition of the main lock component 40, that is, whether the main lock component 40 is in a locked state or an unlocked state; the second detection component 72 is arranged on the moving stroke of the spring tongue component 30, and the spring tongue component 30 can be used to detect whether the door body is closed in place, and the relative positions of the spring tongue components 30 that are closed in place and those that are not closed in place and the second detection component 72 are different, and thus the second detection component 72 Different signals are obtained, and finally it is possible to detect whether the door body is fully closed; the third detection component 73 is arranged on the moving path of the inclined tongue component 20, and when the inclined tongue component 20 switches between the locked and unlocked states, the inclined tongue component 20 and the third detection component 73 switch between approaching and moving away from each other, and in this process they will also abut and then move away, and in this action process the third detection component 73 obtains different signals to detect whether the inclined tongue component 20 has completed locking; in this solution, three groups of detection components are used to detect multiple points of the lock body, so that the user can comprehensively monitor the specific closing status of the current door lock in actual use, effectively reduce safety risks, and improve safety of use.

[0063] Specifically, a PCB board 70 is provided in the housing, and the first detection component 71, the second detection component 72 and the third detection component 73 are all provided on the PCB board 70;

[0064] In the above scheme, this scheme integrates the first detection component 71, the second detection component 72 and the third detection component 73 on the same PCB board 70, which can make it easier to simplify the structure without installing multiple PCB boards 70 in multiple times. It is also more conducive to the integration of the structure and makes the structure more compact.

[0065] For details, see Figure 2 and Figure 6 The tongue assembly 30 includes a tongue body 31, a first fixing rod 32 and a first elastic member 35; a first through hole and a first fixing seat 34 are provided on the housing 10;

[0066] Furthermore, the first fixing rod 32 is slidably disposed in the first fixing seat 34, the tongue body 31 is adapted to extend out of the housing 10 through the first through hole, an abutment portion 33 is disposed on the first fixing rod 32, and a first elastic member 35 is located between the abutment portion 33 and the first fixing seat 34 to drive the tongue body 31 to extend out of the housing 10;

[0067] Specifically, the second detection assembly 72 includes a second micro switch electrically connected to the PCB board 70, and the first fixing rod 32 is suitable for approaching to trigger the second micro switch or moving away from the second micro switch when sliding;

[0068] In the above scheme, when the door body is closed, the tongue body 31 will abut against the door frame and then retract. When the tongue body 31 retracts, it will drive the first fixed rod 32 to retract. The retracted first fixed rod 32 will abut against the second microswitch and further press the spring of the second microswitch to trigger the switch. The trigger switch can be a disconnect signal or a connection signal; it is understandable that, considering that the door body is in a closed state most of the time, the trigger switch can be set to a disconnect signal, which can save power consumption to a certain extent; after the door body is closed, the first elastic member 35 is squeezed to store elastic potential energy. After the door body is opened, the first elastic member 35 releases the elastic potential energy to cause the tongue body 31 to pop out, and the first fixed rod 32 moves away from the second microswitch to achieve signal connection.

[0069] For details, see Figure 3 and Fig. 9 The latch bolt assembly 20 includes a latch bolt body 21, a second fixing rod 22, a sliding plate 23 and a second elastic member 24;

[0070] Furthermore, a second fixing seat 25 and a second through hole are provided in the housing 10, the oblique tongue body 21 is suitable for passing through the second through hole to pass through the housing 10, the second fixing rod 22 is slidably provided in the second fixing seat 25 and connected to the oblique tongue body 21, and the two ends of the second elastic member 24 are respectively abutted against the oblique tongue body 21 and the second fixing seat 25; the sliding plate 23 is connected to the second fixing rod 22 and is slidably provided on the housing 10;

[0071] For further information, see Figure 8 A first toggle portion 61 is formed on the oblique tongue paddle 60, and the first toggle portion 61 is disposed between the second fixed seat 25 and the sliding plate 23 and is suitable for acting on the sliding plate 23 to drive the sliding plate 23 to slide;

[0072] Specifically, the third detection assembly 73 includes a third micro switch electrically connected to the PCB board 70, and the second fixing rod 22 is suitable for approaching to trigger the third micro switch or moving away from the third micro switch when sliding;

[0073] In the above scheme, when the inclined tongue paddle 60 rotates, it can drive the first toggle part 61 to rotate, and the rotation of the first toggle part 61 can act on the sliding plate 23, and the sliding plate 23 drives the second fixed rod 22 to contract, and the second fixed rod 22 is away from the third micro switch when it contracts; when the second fixed rod 22 contracts, it will compress the second elastic member 24, and the second elastic member 24 stores elastic potential energy. After the external force is lost, the second elastic member 24 releases the elastic potential energy, prompting the second fixed rod 22 to reset and then prompting the inclined tongue body 21 to reset; after the second fixed rod 22 is reset, it is close to the third micro switch and triggers the switch by further triggering the spring on the third micro switch; it is understandable that considering that the inclined tongue body 21 is in a pop-up state most of the time, the second fixed rod 22 will press the spring of the third micro switch when it pops up, and it can be set to be a signal disconnection state at this time, so that energy can be saved to a certain extent; it is further understandable that by judging whether the signal of the third micro switch is in a disconnection state or a connection state combined with the second detection component 72, the current state of the inclined tongue body 21 can be further determined.

[0074] For details, see Figure 3 , Figure 7 and Fig.10 , the main lock assembly 40 includes a drive plate 41, a main lock tongue 42, a third elastic member 43 and a main lock plug;

[0075] Specifically, the main lock tongue 42 is connected to the driving plate 41, the driving plate 41 is slidably arranged on the housing 10, a driving hole 411 is opened on the driving plate 41, the main lock is rotatably arranged on the housing 10 and includes a second tooth portion and a driving portion, and the driving portion extends into the driving hole 411;

[0076] Specifically, the handle paddle 50 is provided with a first tooth portion 51 meshing with the second tooth portion, and when the handle paddle 50 rotates, it is suitable for driving the main lock to rotate, so that the driving part drives the driving plate 41 to slide on the housing 10 through the driving hole 411;

[0077] The third elastic member 43 is used to drive the driving plate 41 to reset;

[0078] In the above scheme, when the handle paddle 50 rotates, the main lock can be driven to rotate through the cooperation of the first tooth portion 51 and the second tooth portion; after the main lock is pulled out and rotated, it can drive the driving part to rotate, and the driving part cooperates with the driving hole 411 of the driving plate 41, thereby driving the driving plate 41 to slide in the shell 10. The sliding of the driving plate 41 can drive the main lock tongue 42 to extend into a locked state, or drive the main lock tongue 42 to be retracted into the shell 10 into an unlocked state through sliding.

[0079] Furthermore, in some embodiments, a guide groove may be further provided on the driving plate 41 , and the limiting guide of the movement of the driving plate 41 is achieved by cooperating with a limiting column formed on the shell 10 .

[0080] Specifically, the handle paddle 50 is provided with an arc-shaped groove 52, and the oblique tongue paddle 60 is provided with a second paddle portion 62, and the second paddle portion 62 extends into the arc-shaped groove 52;

[0081] Furthermore, it also includes a square shaft core 11 suitable for passing through the handle paddle 50 and the oblique tongue paddle 60 .

[0082] Specifically, the lock core driving mechanism includes a lock core paddle 81 rotatably disposed on the housing 10 and a fourth elastic member 82 driving the lock core paddle 81 to rotate and reset;

[0083] Specifically, one end of the lock core paddle 81 abuts against the second paddle portion 62 and is suitable for acting on the second paddle portion 62, so that the second paddle portion 62 drives the handle paddle 50 to switch from the first extreme position to the second extreme position;

[0084] Furthermore, a third toggle portion 53 is provided on the handle paddle 50, and when the lock core paddle 81 rotates in a direction away from the first toggle portion 61, it is suitable for acting on the third toggle portion 53 to switch the handle paddle 50 from the second extreme position to the first extreme position;

[0085] In the above scheme, the lock core drive assembly can cooperate with the lock core of the lock to drive the lock core drive assembly to move. The lock core paddle 81 in the lock core assembly can be rotatably arranged on the shell. When the lock core paddle 81 rotates, it can act on the second toggle portion 62, and further drive the handle paddle 50 to rotate through the second toggle. The rotation of the handle paddle 50 further controls the movement of the drive plate 41 through the main lock plugging and unplugging action; when the second toggle portion 62 rotates, the oblique tongue paddle 60 will also rotate. When the oblique tongue paddle 60 rotates, it can act on the sliding plate 23 through the first toggle portion 61 to drive the second fixed rod 22 to retract, thereby realizing the retraction of the oblique tongue body 21.

[0086] The first elastic member 35 and the second elastic member 24 may be compression springs, and the third elastic member 43 and the fourth elastic member 82 may be torsion springs.

[0087] For details, see Figure 3-4 , the first detection component 71 includes a first micro switch electrically connected to the PCB board 70;

[0088] Specifically, the handle paddle 50 is provided with a fourth paddle portion 54;

[0089] Further, when the handle paddle 50 is at the first extreme position, the fourth toggle portion 54 is adapted to act on the first micro switch, and when the handle paddle 50 is at the second extreme position, the fourth toggle portion 54 is away from the first micro switch;

[0090] In the above scheme, when the handle paddle 50 rotates, it will approach or move away from the first micro switch. When it approaches, it will be pressed against the spring of the first micro switch and trigger the switch, and when it moves away from the switch; in some embodiments, it can be understood that the fourth toggle portion 54 on the handle paddle 50 triggers the first micro switch as a connection signal, at which time the main lock tongue 42 extends; when the fourth toggle portion 54 on the handle paddle 50 moves away from the first micro switch, the signal is disconnected, and at this time the main lock tongue 42 retracts into the shell 10.

[0091] For details, see Figure 5 , the PCB board 70 is U-shaped, the second detection component 72 and the third detection component 73 are respectively arranged at the two ends of the U-shaped PCB, and the first detection component 71 is arranged on one side of the U-shaped bottom of the PCB board 70;

[0092] In the above scheme, this scheme can adapt to the positions of the inclined tongue assembly 20, the main lock assembly 40 and the spring tongue assembly 30 by reasonably distributing the positions of the three detection components, so that the structures can be more closely matched, making the structure more compact without causing mutual interference.
