[0023] As attached Figure 1 and attached Figure 2As shown, an electronic door lock includes a lock body (omitted in the figure), a lock core (omitted in the figure), a panel 1 and a door handle 2, the lock core is installed in the lock body, and the lock body and the panel 1 are connected.

[0024] The door handle 2 includes a control mainboard 24 , a handle body 21 , and a data entry module disposed on the handle body 21 .

[0025] The data entry module is electrically connected to the control mainboard 24. The data entry module is a digital password module. The digital password module includes a digital password input panel 22 disposed on the front of the handle body 21. Of course, the data entry module can also be a fingerprint recognition device or a face recognition device. Specifically, the handle body 21 is formed by connecting the upper body 211, the middle body 212 and the lower body 213 in sequence to form a cylindrical shape. The data entry module is disposed in the middle body and the control mainboard 24 is built into the middle body 212. The handle body 21 is a rotating shell. More specifically,

[0026] The handle body 21 is provided with a rotating cover 3 which can rotate around the central axis of the handle body. The rotating cover 3 is provided with a window 31 for revealing the data entry module. The rotation of the rotating cover 3 makes the rotating cover 3 cover or reveal the data entry module for people to enter data.

[0027] In order to realize that the cover 3 covers or reveals the data entry module, one of the ways is as shown in the attached Figure 2 To Attachment Figure 4 As shown, the rotating cover 3 can be in a cylindrical shape, and the inner cylindrical surface of the rotating cover 3 is provided with internal teeth 32. The handle body 21 is fixedly provided with a motor 41 electrically connected to the control main board 24, and the motor shaft of the motor 41 is connected with a motor gear 42. The motor gear 42 is meshed with the internal teeth 32 and drives the rotating cover 3 to rotate back and forth around the rotation center axis of the handle body 21 under the action of the motor 41.

[0028] In order to realize that the cover 3 covers or reveals the data entry module, another method is as shown in the attached Figure 7 As shown, a reset device and a limit device are provided between the handle body 21 and the rotary cover 3. Under the action of the reset device, the rotary cover 3 maintains a state of covering the data entry module. The rotary cover 3 is rotated to overcome the action of the reset device to reveal the data entry module and is limited within a set time limit under the action of the limit device.

[0029] More specifically, the reset device is a torsion spring 5 , which is sleeved on the handle body 21 , with one end 51 of the torsion spring 5 fixedly connected to the handle body 21 and the other end 52 of the torsion spring 5 fixedly connected to the rotary cover 3 .

[0030] The rotating cover 3 is provided with a limiting portion 33, and the limiting portion 33 is preferably a limiting hole. The limiting device includes a driving device 61 and a limiting pin 62. The driving device 61 is connected to the control main board 24 and drives the limiting pin 62 to extend and retract along the radial direction of the rotating cover 3 under the control of the control main board 24. When the rotating cover 3 overcomes the action of the reset device to reveal the data entry module, the limiting pin 62 extends into the limiting hole until the set time limit is reached and then extends out of the limiting hole. Under the action of the reset device, the rotating cover 3 maintains the state of covering the data entry module.

[0031] In addition, a fingerprint recognition module 7 is also provided on the handle body 21, the signal output end of the fingerprint recognition module 7 is connected to the control main board 24, and the fingerprint collection surface of the fingerprint recognition module 7 is arranged to face away from the front of the digital password input panel 22. When in use, people can let their fingers touch the fingerprint collection surface while holding the handle body 21 to directly collect fingerprints, which is more convenient, and the fingerprint collection surface of the fingerprint recognition module 7 is arranged to face away from the front of the digital password input panel 22, which is more conducive to hiding the fingerprint collection surface and improving the anti-theft effect.

[0032] The power sources used by various types of existing electric locks are generally external power sources (transformers, switching power supplies, etc.) or built-in batteries. The use of an external power source requires laying power lines, and the construction process is relatively complicated. In the event of a power outage, the lock core cannot be activated. The use of built-in batteries requires regular battery replacement, and the lock core cannot be driven to operate when the power is insufficient, which is more laborious to use. In order to solve this defect, a generator 81 for supplying power to the control main board 24 is provided in the inner cavity of the handle body 21, and a rotating head 82 that can rotate around the central axis of rotation of the handle body 21 is provided at the lower end of the handle body 21. A power transmission device is provided between the generator 81 and the rotating head 82, and the rotation of the rotating head 82 causes the generator 81 to generate electricity through the power transmission device. In this way, manual power generation can be achieved for emergency unlocking, as shown in the attached Figure 5 and attached Figure 6 In order to increase the friction force, a plurality of grooves are also provided on the peripheral wall of the rotating head 82.

[0033] Conventional handles are directly mounted on the panel 1, that is, the handles are placed in front of the panel 1. When in use, the handles will hinder people from performing various operations on the panel 1. Therefore, as a better embodiment, the handle body 21 of the present invention is connected to the panel 1 by a connecting member 23 that is offset from the panel 1. Figure 8 and attached Fig. 9 As shown, it is possible to prevent the door handle 2 from colliding with the door frame or causing displacement, and it is also more convenient for people to perform various operations on the panel 1 (such as unlocking with a key). Specifically, the upper body 211 and the lower body 213 are respectively connected to the panel 1 through the connecting member 23.

[0034] The electronic door lock also includes a handle 9, a first end of which is hingedly connected to the panel 1 and connected to the lock body to achieve mechanical unlocking or locking, and a second end of the handle 9 extends toward the handle body 21 to the back of the handle body 21. By pulling the second end of the handle 9, the handle 9 can rotate forward or reverse around the hinge center axis of its first end to unlock or lock the lock body. Figure 8 and attached Fig. 9 Thus, when in use, the handle 9 can be pulled at the same time to facilitate mechanical unlocking or locking (based on the central axis of the handle body, the panel 1 is located on the inner side of the handle body, so the unlocking and locking mode is operated from the outer side of the handle body). On the other hand, the second end of the handle 9 is spaced from the first end to form a lever, so that the handle 9 can be pulled with less force.

[0035] As attached Fig.10 To Attachment Fig.12 As shown, the second end of the pull handle 9 is formed with a sector block 91, the end surface of the second end of the pull handle 9 is an arc surface 911 of the sector block 91, and the two sides of the sector block 91 respectively form an upper pull-out recess 92 and a lower pull-out recess 93 corresponding to the pull handle 9. In this way, the pull handle 9 can be pulled with more effort, and the fingers are not easily separated from the pull handle 9 when pulling the pull handle 9, and the rotation angle of opening the pull handle 9 can be increased.

[0036] The end surface 912 of the sector block 91 facing the handle body 21 extends and protrudes toward one side of the handle body 21, and the end surface is smoothly connected to the pull handle 9 through the arc surface 94. This can effectively prevent fingers from being caught between the pull handle 9 and the handle body 21 when pulling the pull handle 9, thereby improving the safety of use.

[0037] The above embodiments are preferred implementations of the present invention, but the implementations of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention are equivalent replacement methods and are included in the protection scope of the present invention.
