[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Example 1:

[0026] In this embodiment, if Figure 1-3 As shown, the utility model proposes an electromechanical integrated lock with separate control of inside and outside handles, including a lock shell 1, one side of the lock shell is connected to the panel support 2, the outer side of the panel support is connected to the panel 3, a micro switch assembly 4 is provided on the top of the lock shell, the micro switch assembly 1 is provided with a motor line 1, a micro switch line 1 and a motor 1, the motor line 1 and the micro switch line 1 share a 4P terminal, the motor line 1 is connected to the motor 1, the output end of the motor 1 is connected to the motor shaft 1 5, the end of the motor shaft 1 is sleeved with a limiting piece component 6, the bottom of the limiting piece component is plugged into one side of the dial 7, the motor 1 drives the motor shaft 1 to extend and retract to drive the limiting piece component to extend and retract to limit the dial, a square hole is provided in the middle of the dial, the handle is inserted in the square hole to control the rotation of the dial, the side of the dial away from the limiting piece component abuts against the rotating rod 8, the top of the push rod 9 is connected to the rotating rod through the rotating rod pin 10, and the middle of the push rod abuts against the oblique tongue component 11;

[0027] A micro switch assembly 2 12 is provided at the bottom of the lock shell. The micro switch assembly 2 is provided with a motor line 2, a micro switch line 2 and a motor 2. The motor line 2 and the micro switch line 2 share a 4P terminal. The motor line 2 is connected to the motor 2. The output end of the motor 2 is connected to the motor shaft 2 13. The end of the motor shaft 2 is sleeved with a motor shaft guide block 14. One end of the pull plate limit piece 15 is inserted on the motor shaft guide block, and the other end of the pull plate limit piece abuts against the pull plate assembly 16. The middle of the pull plate assembly is connected to the bottom of the push rod, and the middle of the push rod abuts against the oblique tongue assembly.

[0028] This embodiment further comprises a connecting sleeve 17 and a fixing pin 18 connected to the middle portion of the lock housing. A safety tongue lever reset spring 19 is wound around the connecting sleeve. A safety tongue lever assembly 20 is connected to the fixing pin. One end of the safety tongue lever reset spring passes through the safety tongue assembly 21, and the other end of the safety tongue lever reset spring abuts the fixing pin. One end of the safety tongue lever assembly abuts the safety tongue assembly, and the other end of the safety tongue lever assembly is connected to the push rod. When the safety tongue lever assembly rotates clockwise, it pushes the safety tongue assembly to retract, twisting the safety tongue lever reset spring and generating a torsional force. This torsional force facilitates the reset of the safety tongue assembly and the safety tongue lever assembly. The safety tongue assembly enhances the anti-theft and anti-pry functions of the lock body.

[0029] This embodiment further comprises a spacer 22 positioned above the dial. Spacer 1 is bolted to the lock housing, the top of which is connected to microswitch cable 1. A spring D23 is positioned at the bottom of spacer 1, with spring D positioned along the rotational path of the dial. When spring D is pressed against one side of the dial, a light indicator connected to microswitch assembly 1 illuminates red, and vice versa.

[0030] This embodiment further features a rotating lever with a rotating lever washer 24 mounted on top. The washer is bolted to the lock housing and is wrapped around a latch bolt return spring 25. One end of the latch bolt return spring abuts the inner wall of the lock housing, while the other end abuts the rotating lever. When the dial rotates clockwise, it compresses the rotating lever, twisting the latch bolt return spring and generating a torsional force that facilitates the return of the rotating lever and dial.

[0031] This embodiment further features a microswitch assembly 3 26 positioned above the latch bolt assembly. A second gasket 27 is connected to the top of the microswitch assembly 3. A spring E 28 is positioned at the bottom of the gasket 2, located along the path of the latch bolt's extension and retraction. When spring E is squeezed by the tail of the latch bolt assembly, a light connected to the microswitch assembly 3 illuminates red; otherwise, it illuminates green.

[0032] In this embodiment, it is further configured that a lock core hole 29 is provided on one side of the micro switch assembly 2, and a lock core can be inserted into the lock core hole. The lock core is not drawn in the figure. A dial shaft 30 is provided above the lock core hole. The dial shaft is fixedly connected to the lock shell. The middle part of the fork assembly 31 is sleeved on the dial shaft. The bottom of the fork assembly is located on the moving path of the lock core. The top of the fork assembly abuts against the middle part of the fork transmission plate 32, and the top of the fork transmission plate abuts against the oblique tongue assembly.

[0033] This embodiment further includes a third gasket 33 on one side of the shift fork assembly, which is bolted to the lock housing. A spring F34 is located on the top of the gasket 3, which abuts the bottom of the shift fork assembly. When the spring F abuts the shift fork assembly, the indicator light connected to the second microswitch assembly illuminates red, and when it does not, it illuminates green.

[0034] In this embodiment, a torsion spring washer 35 is provided below the pull plate assembly, and a torsion spring 36 is wound around the torsion spring washer. One end of the torsion spring is connected to the pull plate assembly, and the other end of the torsion spring abuts against the adjustment assembly 37. The torsion spring twists when the pull plate assembly is displaced to generate a torsion force, which can facilitate the return of the pull plate assembly.

[0035] In this example, micro switch assembly 1, micro switch assembly 2 and micro switch assembly 3 are all connected to two display lights. The red light and green light only represent whether the spring is interfered with, thereby triggering the display light of each switch, correspondingly monitoring the status of the external handle, the status of the lock cylinder and the status of the latch. The colors can be changed.

[0036] The working principle of the electromechanical integrated lock with separate control of inside and outside handles is as follows: when power is turned on, the motor 1 of the micro-switch assembly 1 drives the motor shaft 1 to extend and drive the limit plate component to extend to limit the dial, the dial cannot be rotated, that is, the outside handle cannot be rotated, and the lock cannot be unlocked from the outside, the spring piece D does not contact the dial, and the indicator light connected to the micro-switch assembly 1 shows green; when the motor 1 of the micro-switch assembly 1 drives the motor shaft 1 to contract and drive the limit plate component to contract, the limit plate assembly no longer limits the dial, the outside handle can drive the dial to rotate normally, and the outside unlocking can be completed by the outside handle; the inside handle can always be rotated, and the lock can be manually unlocked from the inside, so that the spring piece D contacts the dial, and the indicator light shows red;

[0037] The motor 2 of the micro switch assembly 2 can drive the motor shaft 2 to retract and drive the motor shaft guide to move downward, thereby causing the pull plate limit piece to rotate counterclockwise, the pull plate assembly to move inward, driving the push rod to rotate counterclockwise, causing the oblique tongue assembly to retract, the safety tongue pull rod assembly to rotate clockwise, the safety tongue assembly to retract inward, and can be unlocked electrically from the inside;

[0038] The lock cylinder can also be rotated to make the shift fork assembly slide obliquely upward, lift the shift fork transmission plate and rotate clockwise, so that the latch bolt assembly will retract, drive the push rod to rotate counterclockwise, and the safety bolt pull rod assembly will rotate clockwise, so that the safety bolt assembly will retract inward and be manually unlocked from the inside. When the latch bolt assembly retracts, the tail of the latch bolt assembly squeezes the spring piece E, and the indicator light connected to the micro switch assembly three shows red, otherwise it shows green when there is no contact. Since the shift fork assembly is separated from the spring piece F, the indicator light connected to the micro switch assembly two shows green, otherwise it shows red when there is contact.
