Description

Technical Field

[0001] This utility model relates to the technical field of fingerprint lock sliding cover structure, specifically to a protective sliding cover structure for fingerprint locks. Background Technology

[0002] Currently, more and more families are choosing to install smart electronic door locks, allowing people to safely open their doors without carrying keys when they leave home, improving convenience. Smart electronic door locks typically have fingerprint unlocking functionality, which is widely used due to its balance of convenience and security. However, the surface of the fingerprint recognition module in smart electronic door locks is prone to dust, dirt, and other debris, affecting the speed and accuracy of fingerprint recognition. Therefore, some smart electronic door locks have protective sliding covers on the fingerprint recognition module surface to prevent dust and other debris from adhering to it. However, since human fingers easily accumulate dust and other debris, during fingerprint recognition, they can easily transfer grease or dirt to the fingerprint recognition module surface. After a period of use, the fingerprint recognition module surface of a smart electronic door lock will still have a large amount of debris adhering to it, affecting the speed and accuracy of fingerprint recognition.

[0003] Based on the above, Chinese Patent Publication No. CN207813262U discloses a sliding fingerprint lock. It includes a bezel, a sliding cover, a fingerprint unlock button, and a lock plate. The bezel has a sliding chamber inside, and the sliding cover is installed inside the sliding chamber. There is a protruding buckle on the top of the sliding cover, and a press switch is located on one side of the protruding buckle. The bezel has an inner sliding groove that matches the sliding cover, and there is a storage compartment below the sliding cover. One end of the bezel has a concave groove that matches the protruding buckle. The sliding cover has two movable grooves that match the protruding buckle and the press switch respectively. There are springs below the telescopic protruding buckle and the press switch, and a connecting plate is engaged between the two springs.

[0004] The aforementioned patent document discloses a fingerprint lock that prevents dust from settling on the fingerprint unlock key by using a sliding cover. This fingerprint lock uses a sliding cover to seal the compartment where the fingerprint unlock key is installed, thereby preventing dust from the environment from settling on the surface of the fingerprint unlock key. However, when the user unlocks the fingerprint lock using the fingerprint unlock key, dirt on the surface of the finger will still adhere to the surface of the fingerprint unlock key. This fingerprint lock does not have a structure to prevent dirt from the surface of the finger from adhering to the fingerprint unlock key or a structure to remove dirt from the surface of the fingerprint unlock key. Moreover, dirt on the surface of the fingerprint unlock key can easily affect the accuracy of fingerprint recognition after a long period of accumulation. Therefore, this fingerprint lock with a sliding cover structure still has room for improvement. Utility Model Content

Detailed Implementation

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A protective sliding cover structure for a fingerprint lock includes a sliding cover body 1 and a base 2. The sliding cover body 1 covers the surface of the base 2, forming a protective cavity between the sliding cover body 1 and the base 2. A fingerprint module hole 21 is provided on the side of the base 2 near the protective cavity. A sliding groove 22 extending along the length direction is provided on the surface of the base 2, and a locking slot 23 is provided on one side of the sliding groove 22 in the width direction. An unlocking button 3 is provided on one side of the sliding cover body 1. A reset spring 31 is provided between the unlocking button 3 and the sliding cover body 1. A locking block 32 is provided on the side of the unlocking button 3 near the base 2, and the locking block 32 is located in the locking slot 23. A wiping block 4 is movably connected to the side of the sliding cover body 1 near the protective cavity. A wiping cotton 41 is sleeved on one end of the wiping block 4 near the base 2. The wiping block 4 is cylindrical in shape and surrounded by a ring of rotating teeth 42. The unlocking button 3 is provided with a rotating rack 33 extending into the protective cavity and matching the rotating teeth 42.

[0021] This utility model discloses a protective sliding cover structure for fingerprint locks that prevents dust from falling on the surface of the fingerprint unlocking module and removes dirt from the surface of the fingerprint unlocking module by wiping. In this sliding cover structure, the base 2 is used to fix it on the surface of the fingerprint lock, and the fingerprint recognition module for recognizing fingerprints is installed and fixed in the fingerprint module hole 21. When the user uses the fingerprint lock to unlock, the fingerprint recognition module in the fingerprint module hole 21 is mainly used for fingerprint recognition and unlocking. The sliding cover body 1 covers the surface of the base 2 and shields the surface of the fingerprint recognition module to prevent dust in the environment from entering the protective cavity, thereby preventing dust from falling on the surface of the fingerprint recognition module, ensuring the cleanliness of the fingerprint recognition module surface, and helping to improve the fingerprint recognition speed and accuracy of the fingerprint recognition module.

[0022] It should be noted that the sliding cover 1 removes the cover of the fingerprint recognition module by sliding along the slide groove 22, thus opening the sliding cover 1 and exposing the fingerprint recognition module. The user can then unlock the fingerprint lock using the fingerprint recognition module. In the reset state, the sliding cover 1 covers the surface of the fingerprint recognition module and is in a closed state. The locking block 32 is located in the locking slot 23, preventing the sliding cover 1 from sliding along the slide groove 22. The user needs to perform the following operations: press the unlock button 3 and squeeze the reset spring 31 to allow the locking block 32 to enter the slide groove 22. Then, push the sliding cover 1 while the locking block 32 slides along the slide groove 22 until the sliding cover 1 is in an open state. At this time, the user can unlock the fingerprint lock using the fingerprint recognition module. After the user completes the unlocking operation, push the sliding cover 1 to reset. The reset spring 31 pushes the unlock button 3 with its elasticity, causing the locking block 32 to re-enter the locking slot 23, thus allowing the sliding cover 1 to return to the closed state.

[0023] With the above structure, it should be further explained that when the sliding cover body 1 is in the closed state, the surface of the wiping cotton 41 at the end of the wiping block 4 is in contact with the surface of the fingerprint recognition module. When the unlock button 3 is pressed, the rotating rack 33 will move synchronously toward the wiping block 4 along with the unlock button 3. At this time, the rotating rack 33 and the rotating gear 42 will rotate the wiping block 4 through meshing transmission. The rotating wiping block 4 will drive the wiping cotton 41 to rotate synchronously and wipe the surface of the fingerprint recognition module. The stains on the surface of the fingerprint recognition module will be removed by the friction between the wiping cotton 41 and the fingerprint recognition module, thereby avoiding the accumulation of stains on the surface of the fingerprint recognition module. The above describes the wiping of the fingerprint recognition module surface by the wiping cotton 41 before fingerprint recognition.

[0024] Furthermore, during the process of closing the sliding cover 1 after the user completes the fingerprint recognition operation, the reset spring 31 will push the unlock button 3 to reset through elastic force. At this time, the rotating rack 33 will move synchronously away from the wiping block 4 along with the unlock button 3. The rotating rack 33 and the rotating gear 42 will mesh and drive the wiping block 4 to rotate again. The rotating wiping block 4 will drive the wiping cotton 41 to rotate again and wipe the surface of the fingerprint recognition module. The above describes the wiping of the fingerprint recognition module surface by the wiping cotton 41 after fingerprint recognition. It can be seen that this utility model avoids dust falling on the surface of the fingerprint recognition module by using the sliding cover 1. Before the user presses the unlock button 3 to open the sliding cover 1 for fingerprint recognition and when the user closes the sliding cover 1 after fingerprint recognition, the wiping block 4 inside the sliding cover 1 will rotate. The rotating wiping block 4 will drive the wiping cotton 41 to rotate synchronously and wipe the surface of the fingerprint recognition module, thereby removing dirt from the surface of the fingerprint recognition module and making the surface clean, which is beneficial to improving the fingerprint recognition speed and accuracy of the fingerprint recognition module.

[0025] As one of the preferred embodiments of this utility model, refer to Figure 2 , Figure 3 The width of the slide groove 22 gradually decreases from the bottom to the top. The slide cover body 1 is provided with a slider 11 that extends along the length direction and matches the slide groove 22 on the side near the protective cavity. The slide cover body 1 can slide along the slide groove 22 through the slider 11, thereby realizing the opening and closing operation of the slide cover body 1. Since the slide groove 22 has a structure in which the width gradually decreases from the bottom to the top, the slide groove 22 can prevent the slider 11 from falling out of the slide groove 22 through the narrow opening, thereby preventing the slide cover body 1 from detaching from the surface of the base 2 and improving the dustproof effect of the slide cover body 1.

[0026] As one of the preferred embodiments of this utility model, refer to Figure 2 , Figure 4 , Figure 5A button hole is provided on one side of the sliding cover body 1. The unlock button 3 is provided with a button shaft 34 that passes through the button hole and extends into the protective cavity. A limiting block 35 is provided at the end of the button shaft 34. The outer diameter of the limiting block 35 is larger than the inner diameter of the button hole. A reset spring 31 is sleeved on the surface of the button shaft 34. When the unlock button 3 is pressed, the unlock button 3 moves along the button hole through the button shaft 34. The limiting block 35 can prevent the button shaft 34 from disengaging from the button hole, and the reset spring 31 sleeved on the surface of the button shaft 34 can reset the pressed unlock button 3.

[0027] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 There are two unlock buttons 3, which are located on opposite sides of the sliding cover body 1. There are two rotating racks 33, which are fixedly connected to the two unlock buttons 3 one by one. The two rotating racks 33 are located on opposite sides of the wiping block 4. When the user opens the sliding cover body 1, he needs to press the two unlock buttons 3 on both sides. The two unlock buttons 3 are engaged with the rotating gears 42 by the two rotating racks 33 located on opposite sides of the wiping block 4. This makes the force on the wiping block 4 more balanced, which helps to improve the stability of the wiping block 4 during rotation. This allows the wiping block 4 to rotate stably and wipe the surface of the fingerprint recognition module through the wiping cotton 41.

[0028] As one of the preferred embodiments of this utility model, refer to Figure 2 , Figure 4 , Figure 5 The sliding cover body 1 has a rotating shaft 12 on the side near the protective cavity. The rotating shaft 12 passes through the axis of one end of the wiping block 4 and is movably connected to the wiping block 4. A buffer spring 5 is provided between the wiping block 4 and the sliding cover body 1. The buffer spring 5 is sleeved on the surface of the rotating shaft 12. The edge of the fingerprint module hole 21 forms a bevel, which makes the inner diameter of the fingerprint module hole 21 gradually increase from the end away from the protective cavity to the end near the protective cavity.

[0029] With the above structure, the wiping block 4 rotates via the rotating shaft 12 and can slide along the extension direction of the rotating shaft 12. The buffer spring 5 pushes the wiping block 4 with elastic force, so that the wiping cotton 41 always has pressure acting on the surface of the fingerprint recognition module. This ensures that there is always friction between the wiping cotton 41 and the surface of the fingerprint recognition module during the rotation of the wiping block 4, so that the wiping cotton 41 can wipe the stains on the surface of the fingerprint recognition module. In addition, during the opening of the sliding cover body 1, the wiping block 4 and the wiping cotton 41 can slide along the inclined surface of the edge of the fingerprint module hole 21 to the surface of the base 2, while squeezing the buffer spring 5. This avoids the height difference between the surface of the base 2 and the surface of the fingerprint recognition module, which would generate greater resistance to the wiping cotton 41 or the wiping block 4, so that the sliding cover body 1 can be opened more smoothly.

[0030] In summary, this utility model prevents dust from falling onto the surface of the fingerprint recognition module by covering the fingerprint module hole 21 where the fingerprint recognition module is installed with the sliding cover body 1. In addition, the wiping block 4 inside the sliding cover body 1 will rotate before the user presses the unlock button 3 to open the sliding cover body 1 for fingerprint recognition and when the user closes the sliding cover body 1 after fingerprint recognition is completed. The rotating wiping block 4 will drive the wiping cotton 41 to rotate synchronously and wipe the surface of the fingerprint recognition module, thereby removing dirt from the surface of the fingerprint recognition module and making the surface clean, which is beneficial to improving the fingerprint recognition speed and accuracy of the fingerprint recognition module.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
