Detailed Implementation Methods

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1 to 8As shown, an electronic door lock with a press-type fingerprint sensor includes an outer door panel 1 and an inner door panel 2. The outer door panel 1 is fixedly installed on the outer end face of the door leaf, and the inner door panel 2 is fixedly installed on the inner end face of the door leaf. A beveled latch shell 3 and a square latch shell 4 are provided between the outer door panel 1 and the inner door panel 2. The beveled latch shell 3 and the square latch shell 4 are parallel and spaced apart from each other, with the square latch shell 4 located above the beveled latch shell 3. The beveled latch shell 3 and the square latch shell 4 are embedded within the door leaf. The oblique tongue housing 3 is provided with an oblique tongue 31, and the square tongue housing 4 is provided with a square tongue 41. The oblique tongue housing 3 is rotatably connected to an oblique tongue lever 32 that can drive the oblique tongue 31 to retract when rotated. The oblique tongue housing 3 is provided with an oblique tongue rotating actuating component. The forked part of the oblique tongue rotating actuating component is inclined and abuts against one end of the oblique tongue lever. When the rotating actuating component rotates, it drives the oblique tongue 31 to retract. The oblique tongue rotating actuating component has a square hole. The oblique tongue lever 32 is square and is inserted into the square hole. The oblique tongue housing 3 is provided with a spring to press the oblique tongue 31 to reset. A square tongue housing 4 is rotatably connected to a square tongue lever 42, which rotates to extend and retract the square tongue 41. The square tongue housing 4 contains a square tongue rotating head with a square tongue fork. One end of the square tongue 41 inside the square tongue housing 4 is hinged to a linkage plate, and the other end of the linkage plate is hinged to the square tongue fork, forming a three-bar linkage mechanism. The hinge pins of the linkage plate and the square tongue fork have a space for movement, allowing the hinge pin to slide along the arc-shaped hole to prevent jamming. Alternatively, the square tongue 41 can be driven by a gear and rack, with a gear on the square tongue rotating head and a rack at one end of the square tongue 41. The inner panel 2 of the door is equipped with a knob 5 that rotates the square tongue lever 42, which is connected to the square tongue lever 42. The inner panel 2 is equipped with an electric drive unit 6 that can drive the latch lever 42 to rotate. The outer panel 1 is equipped with a lock cylinder 11 that can drive the square latch lever 42 and a button 7 that can drive the oblique latch lever 32 to rotate when pressed. The lock cylinder 11, the electric drive unit 6, and the knob 5 can share a single square latch lever 42, or the square latch lever 42 can be composed of multiple segments connected together. The button 7 is equipped with a fingerprint sensor 8 that can send an electrical signal to the electric drive unit 6 to start the electric drive unit 6. The fingerprint sensor 8 is fixed to the upper end of the button 7 that protrudes from the button hole 12, and can be fixed to the button 7 with screws. Pressing the fingerprint sensor 8 can drive the button 7 to rotate. When a finger presses the fingerprint sensor 8, the fingerprint sensor 8 sends an electrical signal to the electric drive unit 6 to open the square latch 41. At the same time, under the action of the pressing force, the button 7 drives the oblique latch 31, thereby opening the door. The structure is simple, easy to use, and has low production cost. Of course, a password module or other control mechanism can also be set on the outer panel 1 to control the start of the electric drive unit 6.

[0025] For ease of use, a button hole 12 is provided at the front end of the outer panel 1. The button 7 is hinged inside the outer panel 1 and one end extends out of the button hole 12. The outer panel 1 is provided with a transmission device 9 that can drive the slanted tongue lever 32 to rotate when the button 7 is pressed and rotated. One end of the hinge shaft of the button 7 extends out of the button hole 12 to the outside of the outer panel 1, and the other end is used to actuate the transmission device 9. The transmission device 9 includes a sliding plate 91 located inside the outer door panel 1, which can be moved up and down when pressed by the button 7. The sliding plate 91 is slidably located inside the outer door panel 1. Two clamping plates are provided inside the outer door panel 1, with a clamping groove between the clamping plates. The sliding plate 91 is located in the clamping groove. The sliding plate 91 has a straight toothed portion 92. The oblique latch lever 32 is fitted with a rotating tooth 93 that can drive the oblique latch lever 32 to rotate and mesh with the straight toothed portion 92. The oblique latch housing 3 has an elastic element that can spring the oblique latch 31 to reset and drive the oblique latch lever 32 to reset. When the oblique latch 31 resets, the oblique latch lever 32 also rotates to reset. The rotation of the oblique latch lever 32 resets the rotating tooth 93, thereby driving the sliding plate 91 and the button 7 to reset. The sliding plate 91 has an inclined surface 94 that abuts against the end of the button 7. The inclined surface 94 is inclined towards the inside of the door and downwards.

[0026] A driven gear 43 is fitted on the square tongue lever 42. The electric drive device 6 includes a motor 61 located in the inner panel 2 of the door and a reduction gear assembly 62 driven by the motor 61. The reduction gear assembly 62 drives the small gear through the large gear, and the output wheel of the reduction gear assembly 62 meshes with the driven gear 43.

[0027] To prevent the motor 61 from starting when it is not needed, for example, when the square tongue 41 is already in the open state (retracted into the housing), the inner panel 2 of the door is equipped with a signal switch 21 that can generate an electrical signal to keep the motor 61 normally closed. The motor 61 is connected in series with the signal switch 21. When the signal switch 21 is open, the motor 61 cannot start and is in a normally closed state. The knob 5 is equipped with a control piece 51 that can control the signal switch 21 to generate an electrical signal when the knob 5 is turned to drive the square tongue 41 to retract into the square tongue housing 4. The signal switch 21 is an infrared sensor with a transmitting end and a receiving end. When the signal between the transmitting end and the receiving end is uninterrupted, the signal switch 21 is on, and the motor 61 can start working when it receives the fingerprint signal. When the control piece 51 is turned between the transmitting end and the receiving end, the signal is interrupted, the signal switch 21 is in the open state, and the motor 61 is in a normally closed state and cannot start when receiving the fingerprint signal.

[0028] The inner panel 2 of the door is provided with a ball handle 22 that can drive the tongue 31 to retract. The ball handle 22 and the tongue lever 32 have two sections connected, one end of which is connected to the ball handle 22 and the other end is connected to the slide plate 91.
