[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 As shown, a fingerprint recognition button protection device includes a lock body 1, a camera 11 is provided on the top front of the lock body 1, a number keypad 12 is provided on the front of the lock body 1, an arc-shaped handle 2 is fixedly installed on the bottom front of the lock body 1, a fingerprint button 21 is provided on the back of the arc-shaped handle 2, and a protective component 3 is provided on the outside of the fingerprint button 21.

[0030] The protective component 3 includes a protective cover 301 fixedly installed on the back of the arc-shaped handle 2. The protective cover 301 has a vent on its right side. An opening cover 302 is installed inside the vent. An insertion interface 303 is provided on the top of the opening cover 302. A connecting post 304 is inserted into the insertion interface 303. The top of the connecting post 304 passes through the opening cover 302 and is fixedly installed on the inner wall of the vent. An installation post 305 is fixedly installed on the bottom of the connecting post 304. A torsion spring 306 is sleeved on the outer surface of the installation post 305. A docking component 4 is provided inside the protective cover 301.

[0031] The fingerprint button 21 is located inside the protective cover 301, and the front of the opening and closing cover 302 is located above the fingerprint button 21.

[0032] Furthermore, by installing a camera 11 and a numeric keypad 12 on the lock body 1, users can conveniently observe the situation outside through the camera 11. Personnel without fingerprint registration can enter a password using the numeric keypad 12 to open the door. An upward-curving arc-shaped handle 2 is installed on the front of the lock body 1, allowing the fingerprint keypad 21 to be mounted on the back of the handle 2, preventing frontal impact. A protective cover 301 is installed on the outside of the fingerprint keypad 21, providing comprehensive protection. Since fingerprint recognition requires pressing a finger on the fingerprint keypad 21, an opening is provided on the right side of the protective cover 301, allowing the user's finger to press onto the fingerprint keypad 21 for recognition. However, dust can enter through the opening; therefore, an opening cover 302 is installed inside the opening. The opening cover 302 has insertion ports 303 at both the top and bottom. Two connecting posts 304 are inserted into both ends of the insertion interface 303. The ends of the two connecting posts 304 furthest from the cover 302 are installed on the inner wall of the opening, allowing the cover 302 to rotate and open inside the opening. A mounting post 305 is fixedly installed on the end of the connecting post 304 inside the insertion interface 303. The diameter of the mounting post 305 is smaller than that of the connecting post 304, allowing a torsion spring 306 to be installed on the outer surface of the mounting post 305. When a finger is inserted into the opening, it pushes the cover 302 inward into the protective cover 301, causing the torsion spring 306 to rotate and generate torque on the cover 302. When the finger is placed on the fingerprint button 21 and the fingerprint is removed from the protective cover 301, the torsion spring 306 is no longer restricted and will rotate back to its original position, causing the cover 302 to close again. This achieves the effect of protecting the fingerprint button 21 and preventing the fingerprint button 21 from being damaged by impact or dust accumulation, which could cause the fingerprint button to be unable to unlock.

[0033] It should be noted that the torsion spring 306 is a mechanical energy storage structure. The torsion spring 306 stores and utilizes energy by twisting or rotating a soft and flexible elastic material, so that the object has a certain mechanical energy. Pushing the opening and closing cover 302 with a finger causes the torsion spring 306 to rotate and generate torque. Releasing the finger causes the torsion spring 306 to reset, so that the opening and closing cover 302 resets and closes again.

[0034] Considering that when a finger is inserted into the protective cover 301 and presses the fingerprint button 21, the pressing position may be inaccurate, causing the lock body 1 to be unable to open, the following is presented: Figure 3 and Figure 6 The specific structure of the docking component 4 is disclosed. The docking component 4 includes a slide rail 401 formed on the top of the inner wall of the protective cover 301. A sliding groove 402 is formed on the back of the inner wall of the slide rail 401. A sliding post 403 is inserted into the sliding groove 402. A sliding block 404 is fixedly installed on the front of the sliding post 403. A pressing plate 405 is fixedly installed on the bottom of the sliding block 404. A return spring 5 is sleeved on the outer surface of the sliding post 403. The front of the return spring 5 is installed on the back of the sliding block 404, and the top of the return spring 5 is installed on the front of the inner wall of the slide rail 401.

[0035] Two pressure plates 405 are provided, and the two pressure plates 405 are located inside the protective cover 301 and are symmetrically distributed vertically. The pressure plates 405 are located on the back of the fingerprint button 21, and a connecting block 6 is fixedly installed on the front of the opening and closing cover 302, and the connecting block 6 is located in the middle of the two pressure plates 405.

[0036] Furthermore, by creating a slide rail 401 on the inner wall of the protective cover 301, the sliding post 403 can be inserted into the sliding groove 402 on the back side of the inner wall of the slide rail 401. A sliding block 404 is then fixedly installed on the end of the sliding post 403 away from the sliding groove 402, and a pressing plate 405 is fixedly installed on the bottom of the sliding block 404. The pressing plate 405 can then move back and forth along the slide rail 401 with the aid of the sliding post 403. A return spring 5 is then sleeved on the outer surface of the sliding post 403, with its top installed on the front side of the inner wall of the slide rail 401 and its bottom installed on the back side of the sliding block 404. After the finger pushes the opening and closing cover 302 into the interior of the protective cover 301, the finger moves towards the back of the curved handle 2. The finger will first contact the pressing plate 405, pushing the pressing plate 405 towards the back of the curved handle 2, so that the finger contacts the fingerprint button 21 to recognize the fingerprint for unlocking. When the finger contacts the two pressing plates 405 and moves towards the fingerprint button 21, the finger will adjust the center of the finger to the middle of the two pressing plates 405 according to the tactile sensation of the pressing plates 405, so that the finger can be accurately aligned with the fingerprint button 21, achieving the effect of precise finger placement for fingerprint recognition and quick unlocking.

[0037] It should be noted that the front of the opening cover 302 is located on the back of the press plate 405, so that the opening cover 302 can open and close normally without being blocked by the press plate 405. However, there will still be a gap between the two press plates 405. The connecting block 6 is then fixedly installed on the front of the opening cover 302 so that the connecting block 6 can block the gap between the two press plates 405, which can further reduce the amount of dust entering the fingerprint button 21.

[0038] In summary, the working principle of this utility model is as follows:

[0039] When unlocking the fingerprint lock, the user grips the curved handle 2 and inserts the fingerprint-registered finger into the protective cover 301. The finger initially presses against the opening / closing cover 302, causing the cover to rotate inwards via the connecting post 304. This rotation of the cover 302 drives the torsion spring 306, generating torque that pushes the finger open the cover 302 and into the protective cover 301. Moving the finger towards the back of the curved handle 2, it contacts the pressing plate 405, which, along with the sliding block 404, moves along the slide rail 401. When the finger touches the two pressing plates 405, it will adjust the position of the finger so that the center of the finger is in the middle of the two pressing plates 405. In this way, the fingerprint can be accurately pressed onto the fingerprint button 21 to unlock the lock body 1. After unlocking, the finger is removed from the protective cover 301, the pressing plate 405 is pulled back to its original position by the return spring 5, and the opening and closing cover 302 is rotated back to its original position by the torsion spring 306, closing the protective cover 301 again. This achieves the effect of protecting the fingerprint button 21 and assisting the user in accurately pressing the fingerprint button 21 to unlock.
