Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to an intelligent lock protection mechanism. Background Art

[0002] A smart lock is a lock that is different from a traditional mechanical lock and is more intelligent and simpler in terms of user security, identification, and manageability.

[0003] At present, a Chinese patent discloses a smart lock protection mechanism (publication number CN218406945U). This smart lock protection mechanism, through the combination of a first protection device, a second protection device and a third protection device, adds a structure and a protection mechanism of the currently common smart lock to ensure that dust does not enter the fingerprint hole and the button during use, and does not affect the recognition of fingerprints.

[0004] Since the above-mentioned first protective device can only seal the fingerprint recognition key, the residual fingerprint information and dirt left during fingerprint recognition will still remain on the surface of the fingerprint recognition key, which will not only affect subsequent fingerprint recognition, but also pose a security risk of leaking fingerprint information, and its practicality is low. Utility Model Content

[0005] The purpose of the present utility model is to solve the above-mentioned problem and to propose a smart lock protection mechanism, which improves the problem that the existing smart lock protection mechanism with fingerprint recognition protection function is difficult to ensure the cleanliness of the fingerprint recognition key, affects the post-fingerprint recognition, and has safety hazards.

[0006] A smart lock protection mechanism comprises: a protection device; wherein the protection device comprises a fingerprint recognition key installation frame, a sealing door is hinged inside the fingerprint recognition key installation frame, a sponge cleaning block is bonded to one end of the sealing door, a locking structure that is clamped with the fingerprint recognition key installation frame is installed inside the sealing door, during the rotation of the sealing door, the sealing door drives the sponge cleaning block to rotate and wipe the fingerprints and dirt remaining on the surface of the fingerprint recognition key, so that the surface of the fingerprint recognition key is always kept clean, which can not only ensure that the fingerprint recognition key does not interfere with fingerprint recognition to improve the success rate of fingerprint recognition, but also reduce the probability of fingerprint leakage, thereby improving the safety factor of the smart lock.

[0007] Preferably, a positioning groove is provided on the inner bottom wall of the fingerprint recognition key mounting frame, and a mounting cavity connected to the positioning groove is provided on the bottom of the sealing door, and the locking structure includes a positioning block slidably connected to the inside of the mounting cavity, and the bottom of the positioning block passes through the mounting cavity and is engaged with the positioning groove. The locking structure can firmly lock the sealing door and the sponge cleaning block inside the fingerprint recognition key mounting frame, which can prevent external dust from covering the surface of the fingerprint recognition key, so as to improve the dustproof effect of the fingerprint recognition key.

[0008] Preferably, the local cross-sectional shapes of the positioning groove and the positioning block that are engaged with the positioning groove are all matching right-angled triangles, and the inclined surfaces of the positioning groove and the positioning block are facing the direction of the sponge cleaning block, which can reduce the difficulty of the user locking the sealing door and make the user's operation more convenient.

[0009] Preferably, the locking structure also includes a rotating wheel rotatably connected to the inside of the installation cavity, one end of the rotating wheel passes through the installation cavity and extends to the outside of the sealed door, and the surface of the rotating wheel is fixedly connected to a connecting belt fixedly connected to the positioning block. The user can accurately adjust the position of the positioning block through the rotating wheel and the connecting belt, which further facilitates the user's use.

[0010] Preferably, the distance between the rotating wheel and the positioning block is greater than the local length of the positioning block and the positioning groove, which can ensure that the rotating wheel can completely retract the positioning block into the installation cavity by winding the connecting belt.

[0011] Preferably, one end of the rotating wheel is fixedly connected to an adjustment handle, and the corners of the adjustment handle are rounded, so that the user can adjust the rotating wheel more stably through the adjustment handle, which further facilitates the user's adjustment operation.

[0012] Preferably, the locking structure also includes a spring arranged inside the installation cavity, and the top and bottom of the spring are between the installation cavity and the positioning block. The spring is always in a compressed state, which can ensure that the positioning block can automatically and quickly reset after losing resistance without manual adjustment by the user.

[0013] Preferably, there are two springs, which are symmetrically distributed on both sides of the rotating wheel, which can make the positioning block more balanced in force and reduce the probability of the positioning block getting stuck in the installation cavity due to tilting or rotation.

[0014] The beneficial effects of the utility model are:

[0015] 1. During the rotation of the sealed door, the sealed door drives the sponge cleaning block to rotate and wipe the fingerprints and dirt remaining on the surface of the fingerprint recognition key, so that the surface of the fingerprint recognition key is always kept clean, which can not only prevent the fingerprint recognition key from interfering with the fingerprint recognition to improve the success rate of fingerprint recognition, but also reduce the probability of fingerprint leakage, thereby improving the safety factor of the smart lock;

[0016] 2. The locking structure can firmly lock the sealing door together with the sponge cleaning block inside the fingerprint recognition key installation frame, which can prevent external dust from covering the surface of the fingerprint recognition key to improve the dustproof effect of the fingerprint recognition key.

DETAILED DESCRIPTION

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

[0024] When implementing: Figure 1-5 As shown, a smart lock protection mechanism includes: a protection device 1; wherein the protection device 1 includes a fingerprint recognition key mounting frame 11, a sealing door 12 is hinged inside the fingerprint recognition key mounting frame 11, a sponge cleaning block 13 is bonded to one end of the sealing door 12, and a locking structure 14 that is clamped with the fingerprint recognition key mounting frame 11 is installed inside the sealing door 12. The production personnel need to install the fingerprint recognition key on the inner bottom wall of the fingerprint recognition key mounting frame 11, and use a sponge cleaning block 13 that can completely cover the fingerprint recognition key. The specific size needs to be selected according to actual conditions and is not elaborated here. The surfaces of the fingerprint recognition key mounting frame 11, the sealing door 12 and the adjustment handle 144 are all coated with an anti-fingerprint coating, which can reduce the probability of residual fingerprints on the surface of the above-mentioned structure, further improving the safety factor of use.

[0025] like Figure 4 and Figure 5As shown, a positioning groove 111 is provided on the inner bottom wall of the fingerprint identification key installation frame 11, and a mounting cavity 121 connected to the positioning groove 111 is provided at the bottom of the sealing door 12. The locking structure 14 includes a positioning block 141 slidably connected to the inside of the mounting cavity 121, and the bottom of the positioning block 141 passes through the mounting cavity 121 and is engaged with the positioning groove 111; the partial cross-sectional shapes of the positioning groove 111 and the positioning block 141 engaged with the positioning groove 111 are all matching right-angled triangles, and the inclined surfaces of the positioning groove 111 and the positioning block 141 face the direction of the sponge cleaning block 13; the locking structure 14 also includes a rotating wheel 142 rotatably connected to the inside of the mounting cavity 121, and one end of the rotating wheel 142 passes through the mounting cavity 121. The cavity 121 extends to the outside of the sealed door 12, and the surface of the rotating wheel 142 is fixedly connected with a connecting belt 143 fixedly connected to the positioning block 141; the distance between the rotating wheel 142 and the positioning block 141 is greater than the local length of the positioning block 141 and the positioning groove 111; one end of the rotating wheel 142 is fixedly connected with an adjusting handle 144, and the corners of the adjusting handle 144 are rounded; the locking structure 14 also includes a spring 145 arranged inside the installation cavity 121, the spring 145 is located between the installation cavity 121 and the positioning block 141, and the spring 145 is always in a compressed state; the number of springs 145 is two, and the two springs 145 are symmetrically distributed on both sides of the rotating wheel 142.

[0026] When the present invention is in use, when the user needs to use the fingerprint recognition function, the user first rotates the adjustment handle 144, the adjustment handle 144 drives the rotating wheel 142 to rotate, the rotating wheel 142 rotates to reel up the connecting belt 143, the connecting belt 143 lifts the positioning block 141, so that the positioning block 141 is separated from the positioning groove 111, and until the positioning block 141 is completely retracted into the interior of the installation cavity 121, at this time the sealing door 12 is no longer blocked, the user can rotate the sealing door 12, so that the fingerprint recognition key is exposed, and then the user can perform the fingerprint recognition operation normally;

[0027] When the fingerprint recognition is completed, the user only needs to rotate the sealing door 12 back into the fingerprint recognition key installation frame 11. During this process, the fingerprint recognition key installation frame 11 contacts the inclined surface of the positioning block 141 in advance, and squeezes the positioning block 141 back into the installation cavity 121. When the sealing door 12 completely enters the interior of the fingerprint recognition key installation frame 11, and the installation cavity 121 is aligned with the positioning groove 111, the positioning block 141 loses its obstruction. Under the action of gravity and the push of the spring 145, the positioning block 141 quickly engages with the positioning groove 111, and the sealing door 12 is firmly locked in the interior of the fingerprint recognition key installation frame 11.

[0028] During the rotation of the sealing door 12, the sealing door 12 drives the sponge cleaning block 13 to rotate together. The sponge cleaning block 13 rotates and wipes the fingerprint recognition key in the way. The sponge cleaning block 13 can wipe off the fingerprints and dirt remaining on the surface of the fingerprint recognition key, so that the surface of the fingerprint recognition key is always kept clean, which can not only prevent the fingerprint recognition key from interfering with fingerprint recognition to improve the success rate of fingerprint recognition, but also reduce the probability of fingerprint leakage, thereby improving the safety factor of the smart lock.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
