DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] According to the embodiments of the present disclosure, an emergency energy storage mechanism 3, a light receiving adjustment mechanism 4, a fingerprint identifier storage mechanism and a fingerprint identifier 5 are provided on the door lock body; the emergency energy storage mechanism 3 is used to temporarily provide power to the door lock when the door lock is short of power; the light receiving adjustment mechanism 4 is used to adjust the light receiving angle and store the fingerprint identifier 5; the fingerprint identifier storage mechanism is used to store the fingerprint identifier 5 after receiving the sensor instruction.

[0025] According to an embodiment of the present disclosure, Figure 1 , Figure 2 As shown, the door lock body includes an outer panel 1, an outer door handle 2, a mechanical lock hole 6, a keyboard 7, a battery 8, an inner panel 9, an inner door handle 10, and a lock core 11; the emergency energy storage mechanism 3 includes a hand-cranked generator 31 and a turning handle 36; the output end of the hand-cranked generator 31 is electrically connected to the battery 8; the hand-cranked generator 31 and the turning handle 36 are connected through a transmission mechanism, so that when the turning handle 36 is rotated, the hand-cranked generator can provide power to the battery.

[0026] In this embodiment, the hand-cranked generator converts mechanical energy into electrical energy by rotating the coil in the magnetic field.

[0027] According to the embodiments of the present disclosure, Figure 3 As shown, the transmission mechanism includes a fixed rod 32 fixedly connected to the input end of the hand-cranked generator 31, and a plurality of limit grooves 33 are provided on the outer side of the fixed rod 32. The corresponding movable pins 34 are movably provided inside the plurality of limit grooves 33. The top of the movable pin 34 is provided with a sliding sleeve 35. The outer side of the sliding sleeve 35 is movably connected to the inner side of the top of the outer door handle 2. The top of the sliding sleeve 35 is movably connected to the turning handle 36. The top of the turning handle 36 abuts against the inner side of the top of the outer door handle 2. When the device is out of power for a long time and there is no sunlight, and the user does not carry a mechanical key, by pulling the sliding sleeve 35 out from the inner side of the top of the outer door handle 2, adjusting the position of the turning handle 36, manually rotating the turning handle 36, and rotating the hand-cranked generator 31 to start charging the battery 8, the normal operation of the device is ensured by charging the battery 8. After the emergency charging is completed, the emergency energy storage mechanism 3 is recovered and stored in the inner side of the outer door handle 2, so as to improve the dust and damage protection of the emergency energy storage mechanism 3 and improve the service life of the emergency energy storage mechanism 3.

[0028] In some embodiments, the structure of the transmission mechanism is capable of driving the handle 36 to extend out of the outer door handle 2. Other structures may also be used, such as directly using a telescopic rod structure for the handle 36 and electrically connecting it to the hand-cranked generator 31.

[0029] According to the embodiment of the present disclosure, the light receiving adjustment mechanism 4 includes a linear slide 41, the bottom end of the linear slide 41 is arranged at the top end of the outer panel 1, a universal joint 42 is arranged on the side of the linear slide 41 close to the outer panel 1, a fixed plate 47 is arranged on the side of the universal joint 42 away from the linear slide 41, and a photovoltaic panel 48 is abutted on the top end of the fixed plate 4, and the output end of the photovoltaic panel 48 is electrically connected to the battery 8. When the photovoltaic panel 48 can receive sunlight, the light receiving angle of the photovoltaic panel 48 can be adjusted by rotating the universal joint 42 to ensure that the photovoltaic panel 48 receives more sunlight to generate electricity under sunlight. When the device is installed in an indoor environment, the photovoltaic panel 48 can be pulled out from the inner side of the fixed plate 47 and placed outdoors for charging.

[0030] According to an embodiment of the present disclosure, the fingerprint identifier storage mechanism includes a brightness sensor 43 disposed on a fixed plate 47 corresponding to the position of the fingerprint identifier 5 and a pressure sensor 46 disposed in the inner wall cavity of the inner plate 9. The detection signal output end of the brightness sensor 43 and the detection signal output end of the pressure sensor 46 are both connected to the detection signal receiving end of the controller, and the detection signal output end of the controller is connected to the detection signal receiving end of the linear slide. When the user needs the fingerprint identifier 5 to identify, he places his hand on the brightness sensor 43 on the fixed plate 47. The brightness sensor 43 detects that the brightness at its position suddenly decreases and transmits a signal to the controller. The controller receives the signal transmitted by the brightness sensor and controls the linear slide 41 to move upward by a set distance, so that the fingerprint identifier 5 can be released from the stored state and the fingerprint can be input.

[0031] In some embodiments, the distance that the linear slide 41 moves upward can be designed according to actual needs so as to release the storage state of the fingerprint identifier 5.

[0032] According to the embodiment of the present disclosure, the pressure sensor 46, the gravity ball 44 and the slide plate 45 are located in the same cavity, wherein the gravity ball 44 is set to roll on the slide plate 45, the slide plate 45 is arc-shaped, the highest point of the slide plate 45 is set on the inner wall of the inner plate 9, and the arc of the slide plate 45 makes the gravity ball 44 roll towards the pressure sensor 46 and give it a pressure signal when the door is closed. When the fingerprint recognition is successful, when the user closes the door, due to the inertia, the gravity ball 44 will instantly roll from the lowest point of the slide plate 45 to the pressure sensor 46, and the pressure sensor 46 will transmit the signal to the controller. The controller receives the signal transmitted by the pressure sensor 46 and controls the linear slide 41 to move downward by a set distance, so that the fingerprint identifier 5 is re-stored. After closing the door, due to the loss of inertia, the gravity ball 44 will roll back to the lowest point along the slide plate 45, completing the shielding protection of the fixed plate 47 and the photovoltaic panel 48 on the fingerprint identifier 5, preventing criminals from directly discovering the fingerprint identifier 5 and completing the user's fingerprint residue extraction.

[0033] In some embodiments, the gravity ball 44 can be made of different materials, such as metal or rubber, so that when rolling, it can generate a pressure value that can be detected by the pressure sensor 46.

[0034] In some embodiments, a pull ring may be fixedly connected to the top of the sliding sleeve 35 , and the inner side of the sliding sleeve 35 is slidably connected to the outer side of the fixing rod 32 , so that the user can pull out the sliding sleeve 35 with less effort.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0036] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
