[0013] Figure 3 This is a schematic diagram of the unlocking plate structure of the utility model. DETAILED DESCRIPTION

[0014] like Figure 1-Figure 3As shown, an electronic lock body for an inner door comprises a housing 9 and an inclined tongue 1 and a straight tongue 2 movably mounted thereon, a lock core 3 for relatively rotating is arranged in the housing 9, and further comprises a motor 4, a cam 5, a steering switch 6, a toggle plate 7 and an insert switch 8, wherein the cam 5 is assembled in linkage with the output shaft of the motor 4, a square shaft 10 for movably assembling the toggle plate 7 is arranged in the housing 9, the toggle plate 7 rotates circumferentially by abutting against the cam 5, the inclined tongue 1 is provided with a connected connecting shaft 11 in the housing 9, an elastic member for elastically pushing the inclined tongue 1 out of the housing 9 is arranged on the connecting shaft 11, and the inclined tongue 1 is received into the housing 9 through a linkage rod of the toggle plate 7 and the connecting shaft 11, the steering switch 6 is electrically connected to the motor 4, the lock core 3 is provided with a synchronously rotating flange 12 at the outer edge, the lock core 3 rotates to drive the flange 12 to enter the sensing area of ​​the insert switch 8, and the straight tongue 2 is provided with a push-back portion 13 abutting against the flange 12 for linkage reset. The oblique tongue 1 has an elastic locking effect, or has a locking tendency, and the linkage of the straight tongue 2 and the oblique tongue 1 is a mature technical means. For example, in the present embodiment, an unlocking plate 14 is provided, and the two ends of the unlocking plate 14 are respectively linked to the straight tongue 2 and the toggle plate 7. The main innovation is that, on the one hand, the motor 4 drives the cam 5, the toggle plate 7, the connecting shaft 11 and the oblique tongue 1 to move, and on the other hand, the rotation of the lock cylinder 3 triggers the internal switch 8 and the related fingerprint unlocking circuit, and resets by linkage with the straight tongue 2. The cam 5 has various styles, and the output direction can be converted by using an arc surface, etc., that is, it is used in this application to convert the output torque of the motor 4 into the rotation power of the toggle plate 7, or the motor 4 directly uses a linear motor, which will not be elaborated or limited too much here.

[0015] In specific use, it can play a variety of functions, among which the electronic plug-in mode is that the flange 12 and the plug-in switch 8 are against the trigger circuit, and the lock core 3 is rotated after the door is closed, and the switch is energized by the protrusion of the lock core 3. At this time, the general fingerprint outside cannot open the door, and only the fingerprint of the administrator can open the door. When the door is opened from the inside, the straight tongue 2 automatically pushes the flange 12 of the lock core 3 to automatically release this function. In the electronic unlocking structure, the electronic unlocking adopts the rotation of the cam 5 to realize the inside and outside door opening. When the lock body is installed, the side facing inward turns the switch 6 to that side, so that the cam 5 is usually inside, ensuring that the inside is in the normally open state. When the electrical signal is input, the cam 5 turns to the outside to open the door. Generally, the cam 5 automatically turns to the normally open state inside after 6 seconds. The toggle plate 7 connection mode, the toggle plate 7 can be divided into two inside and outside, and each cover plate is partially bent and limited. The electronic reversing mode inside and outside the lock body, the steering switch 6 is turned to ensure that the cam 5 is in the normally open state inside, and the motor 4 is changed by the switch to rotate the cam 5 to the normally open state inside. The motor 4 fixing structure is clamped by the fixing frame and then fixed on the unlocking plate 14 by screws. The insertion action is automatically released, and the bulge of the lock core 3 is released by the straight tongue 2 plate to form a switch. The outer shell is reduced in width, and the outer split hole is reduced in the lock body, so that the lock body is smaller and more convenient to install. Emergency mechanical unlocking, if there is no power supply or the circuit fails, the unlocking plate 14 is driven by the mechanical key through the flange 12 of the lock core 3 to unlock.

[0016] The elastic member includes a first spring 15, a second spring 16, a first positioning piece 17 and a second positioning piece 18. The first spring 15 and the second spring 16 are both sleeved on the connecting shaft 11. The two ends of the first spring 15 abut against the oblique tongue 1 and the first positioning piece 17 respectively. The two ends of the second spring 16 are connected to the first positioning piece 17 and the second positioning piece 18 respectively. The first positioning piece 17 is fixedly connected to the housing 9. The second positioning piece 18 is slidably assembled with the connecting shaft 11, and the connecting shaft 11 is provided with a blocking portion 19 at the end to limit the second positioning piece 18 from being disengaged. The first spring 15 is in an elastically stretched state, and the second spring 16 is in an elastically contracted state. The first positioning piece 17 is relatively fixed, and the second positioning piece 18 is relatively movable, so that the connecting shaft 11 and the oblique tongue 1 have a tendency to move toward the outside of the housing 9. When the toggle plate 7 abuts against the second positioning piece 18, the second spring 16 is stretched, so that the connecting shaft 11 and the oblique tongue 1 move into the housing 9. In addition, a blocking portion 19 is provided to block the second positioning piece 18 and perform abutment linkage relative to the housing 9.

[0017] The straight tongue 2 is provided with a linear guide groove 22, and in this embodiment, the guide groove is inclined relative to the moving path of the unlocking plate 14. It also includes an unlocking plate 14 and a fixing frame that are linked to the straight tongue 2. The motor 4 is snap-fitted with the fixing frame, and the fixing frame is threadedly connected to the unlocking plate 14 by screws. The unlocking plate 14 is provided with a guide portion 21 that slides with the guide groove 22, and the toggle plate 7 has a protruding linkage portion 23. The guide portions 21 can be arranged in pairs, and the other is designated at a position that does not hinder the moving route and is close to the outer contour of the straight tongue 2. The unlocking plate 14 converts the relative lateral movement into longitudinal linear movement through the guide groove 22. It should be pointed out that the principles of connecting the toggle plate 7 or the straight tongue 2 at both ends of the unlocking plate 14 are different. The former is a contact steering transmission through different motion paths to directly push the toggle plate 7 to rotate, and the latter is a direction-changing transmission realized by the degree of freedom restriction of the straight tongue 2. The straight tongue 2 is affected by the assembly method and can only perform linear reciprocating motion. The unlocking plate 14 is also provided with a contact part 20 that contacts and drives the toggle plate 7. The relative upward and downward movement of the contact part 20 directly pushes the two ends of the toggle plate 7, namely the linkage parts 23. The unlocking plate 14 is further designed on the basis of the control of the motor 4, and plays a role in the normally open or closed state when moving upward, which excludes the function of the motor 4 to a certain extent, but the actual use varies with the specific design.

[0018] The housing 9 is composed of an upper cover plate, a bottom cover plate and a panel placed on one end of the two, which is a common split structure, which is convenient for production and assembly. The housing 9 is provided with a battery cover and a built-in battery box on one side of the panel, which illustrates the internal power supply method.
