[0037] As attached Figure 1 To Attachment Figure 4 As shown, an electronic lock body includes a lock shell 101, a PCB board 1, a lock body control module, a square tongue assembly 2, a square tongue transmission device, a motor assembly 3, a lock core 102, an oblique tongue assembly 4 and a triangular tongue assembly 5. The square tongue transmission device acts on the square tongue assembly 2 to make the square tongue extend or retract into the lock body (or the lock shell 101) to achieve the locking and unlocking functions of the lock body. The lock core 102 is connected to the square tongue assembly 2.

[0038] As attached Figure 5 To Attachment Figure 8As shown, the square tongue transmission device includes a lever 61 and a motor gear 62 rotatably mounted on the same first pivot shaft 103. The motor gear 62 has an arc-shaped groove 621 extending in an arc with the first pivot shaft 103 as the central axis; as shown in the appendix Figure 9 and the appendix Figure 10 As shown, the lever 61 has a lever projection 611 that falls into the arc-shaped groove 621 and can slide along the arc-shaped groove 621 during rotation; the motor gear 62 is driven by the motor assembly 3 to rotate forward (in the clockwise direction as shown in the appendix Figure 15 to the appendix Figure 25 shown, and the same applies hereinafter) or reverse (in the counterclockwise direction as shown in the appendix Figure 15 to the appendix Figure 25 shown, and the same applies hereinafter). The forward or reverse rotation of the motor gear 62 causes the two end portions of the arc-shaped groove 621 to act on the lever projection 611 respectively, corresponding to causing the lever 61 to rotate forward or reverse. The forward or reverse rotation of the lever 61 pulls the square tongue assembly 2 to extend the square tongue out of the lock body or retract it into the lock body; after the square tongue extends out of the lock body or retracts into the lock body, the motor gear 62 rotates to a reset position under the drive of the motor assembly 3 (as shown in the appendix Figure 15 or the appendix Figure 27 shown). During the process of the pick of the lock core 102 pulling the square tongue assembly 2 to extend the square tongue out of the lock body or retract it into the lock body, the lever projection 611 slides along the arc-shaped groove 621 without touching the two end portions of the arc-shaped groove 621. Thus, during the process of mechanical unlocking through the lock core 102, the lever 61 does not drive the motor gear 62 but only idles relative to the motor gear 62, making unlocking or locking very labor-saving.

[0039] The lock body further includes a first microswitch 11 and a second microswitch 12 mounted on the PCB board 1. When the square tongue extends out of the lock body or retracts into the lock body, the first microswitch 11 and the second microswitch 12 are respectively triggered to generate signals. The lock body control module receives the generated signals and sends instructions to the motor assembly 3 according to the signal content, and the motor assembly 3 drives to make a forward or reverse rotation action, thereby realizing the functions of electronic unlocking (as shown in the appendix Figure 21 to the appendix Figure 26 shown) and locking (as shown in the appendix Figure 16 to the appendix Figure 20 shown).

[0040] It should be noted that the first microswitch 11 and the second microswitch 12 can adopt other induction switches, such as photoelectric switches, etc., and their purpose is to detect whether the relevant components are in place.

[0041] Specifically, a first contact portion 21 is provided on the square tongue assembly 2. When the square tongue extends out of the lock body, the first contact portion 21 touches the first microswitch 11. A second contact portion 51 is provided on the triangular tongue assembly 5. When the triangular tongue of the triangular tongue assembly 5 retracts into the lock body, the second contact portion 51 touches the second microswitch 12.

[0042] A third contact portion 622 is provided on the motor gear 62, and the lock body also includes a third micro switch 13 installed on the PCB board 1. When the motor gear 62 rotates to the reset position, the third contact portion 622 touches the third micro switch 13 to generate a signal. The lock body control module receives the signal and sends an instruction to the motor component 3 according to the signal content, and the motor component 3 stops moving.

[0043] The lock body also includes a latch stopper 7, as shown in the attached Figure 11 and attached Figure 12 As shown, the latch bolt stopper 7 is kept in a state of preventing the latch bolt of the latch bolt assembly 4 from being retracted into the lock body under the action of a reset spring; a pulling block 623 is provided on the motor gear 62, and when the motor gear 62 acts on the pull rod 61 to reversely pull the square bolt assembly 2 to retract the square bolt into the lock body, the pulling block 623 acts on the latch bolt stopper 7 to overcome the action of the reset spring and allow the latch bolt of the latch bolt assembly 4 to be retracted into the lock body.

[0044] The lock body also includes a fourth micro switch 14 installed on the PCB board 1 and connected to the lock body control module. The fourth contact portion 71 is provided on the oblique tongue limiter 7. The pull block 623 acts on the oblique tongue limiter 7 (as shown in the attached Figure 18 When the fourth contact portion 71 touches the fourth micro switch 14, the fourth contact portion 71 moves to the position indicated by the label 73 in the figure to overcome the effect of the reset spring.

[0045] The lock body also includes a fifth micro switch 15 installed on the PCB board 1 and connected to the lock body control module. A fifth contact 41 is provided on the latch bolt assembly 4. When the latch bolt of the latch bolt assembly 4 is retracted into the lock body, the fifth contact 41 touches the fifth micro switch 15.

[0046] The lock body also includes a square tongue trigger device, which includes a mechanical gear 81 installed on the second pivot shaft 104, and a straight tooth 72 meshing with the mechanical gear 81 is provided on the oblique tongue limiting plate 7. The mechanical gear 81 is provided with a trigger head 811, and the square tongue assembly 2 is provided with a trigger part 22. When the lock core 102 pulls out the square tongue assembly 2 to retract the square tongue into the lock body, the trigger part 22 acts on the trigger head 811 to rotate the mechanical gear 81, and the mechanical gear 81 and the straight tooth 72 on the oblique tongue limiting plate 7 are meshed for transmission. The oblique tongue limiting plate 7 overcomes the action of the reset spring and allows the oblique tongue of the oblique tongue assembly 4 to retract into the lock body.

[0047] The lock body can also realize the function of unlocking by lifting or pressing the handle, and the specific structure is as follows.

[0048] The lock body that can be lifted up and pressed down to unlock comprises a handle assembly, which comprises a handle, a square steel and a base 91 rotatably mounted on a lock housing 101, wherein the base 91 and the handle are connected via the square steel.

[0049] As shown in the attached Figure 13 and the attached Figure 14 As shown, a rib 911 extending along the axis of the base 91 is provided on the outer wall of the base 91; the lock body further includes a corresponding forward pull piece 92 and a reverse pull piece 93. The forward pull piece 92 and the reverse pull piece 93 are respectively provided with a forward groove 921 and a reverse groove 931 that arc-extend with the rotation axis of the base 91 as the central axis. The forward pull piece 92 and the reverse pull piece 93 are respectively provided with a forward tooth 922 and a reverse tooth 932. The forward pull piece 92 and the reverse pull piece 93 are rotatably sleeved on the base 91 and the rib 911 passes through the forward groove 921 and the reverse groove 931 at the same time; the pull rod 61 rotatably mounted on the first pivot shaft 103 has an upper pull rod tooth 612 and a lower pull rod tooth 613; the forward tooth 922 of the forward pull piece 92 is meshed and connected with the lower pull rod tooth 613, and the reverse tooth 932 of the reverse pull piece 93 is meshed and connected with the upper pull rod tooth 612 through a reversing gear 82; when the base 91 rotates forward, the rib 911 abuts against one end of the forward groove 921 and causes the forward pull piece 92 to rotate forward while the reverse pull piece 93 remains stationary, and the pull rod 61 rotates in reverse, and the square tongue retracts into the lock body; when the base 91 rotates in reverse, the rib 911 abuts against one end of the reverse groove 931 and causes the reverse pull piece 93 to rotate in reverse while the forward pull piece 92 remains stationary, the reversing gear 82 rotates forward, and the pull rod 61 rotates in reverse, and the square tongue retracts into the lock body. Thus, whether the handle is lifted or pressed down, the square tongue retracts into the lock body, so as to achieve the purpose of unlocking whether the handle is lifted or pressed down.

[0050] The lock body further includes an inclined tongue assembly 4 and an inclined tongue limiting piece 7. Under the action of a return spring, the inclined tongue limiting piece 7 maintains a state of preventing the inclined tongue of the inclined tongue assembly 4 from retracting into the lock body; a driven piece 94 that follows the base 91 is sleeved on the base 91, and the driven piece 94 is provided with a driven tooth 941; a contact piece 83 meshed with the driven tooth 941 is further installed on the lock shell 101, and a contact post 831 is provided on the contact piece 83; when the base 91 rotates forward, the driven piece 94 rotates forward, and the contact post 831 acts on the inclined tongue limiting piece 7 (at the position indicated by the reference numeral 75 in the attached Figure 18 to overcome the action of the return spring and allow the inclined tongue of the inclined tongue assembly 4 to retract into the lock body.

[0051] The driven piece 94 is provided with a driven convex block 942; when the base 91 rotates in reverse, the driven piece 94 rotates in reverse, and the driven convex block 942 acts on the inclined tongue limiting piece 7 (at the position indicated by the reference numeral 74 in the attached Figure 18 to overcome the action of the return spring and allow the inclined tongue of the inclined tongue assembly 4 to retract into the lock body.

[0052] The handle assembly further has a base 91 reset device. The base 91 reset device includes an upper cover plate 95, a lower cover plate 96 and a torsion spring 97. The upper cover plate 95 and the lower cover plate 96 are sleeved on the base 91 and follow the movement of the base 91. The lower cover plate 96 has a first torsion post, and a second torsion post is provided on the lock housing 101. The torsion spring 97 is sleeved on the base 91 and is located between the upper cover plate 95 and the lower cover plate 96. One torsion leg of the torsion spring 97 abuts against the first torsion post while the other torsion leg abuts against the second torsion post, thereby ensuring that the handle can be reset after being lifted or depressed.
