[0031] Applicants find that the key cover designs on the market are various, some of which use steel sheets fixed in hard covers and install magnets on the back of both sides of the lock core hole to achieve adsorption; some use hard key covers with long circular shafts on the back, which are inserted into the circular hole below the lock core hole and fixed through springs and screws to ensure that the key cover can cover the lock core hole. There is also a solution that a hard plastic is formed by injection molding, and then a soft plastic is formed again, and a reverse buckle is used on the soft plastic to constrain the key cover to cover the lock core hole. However, with the increasing cost pressure on the market, the cost advantage of the above solutions is no longer obvious. In addition, these designs inevitably have the problem of activity gap and shaking between the key cover and the keyhole, which not only affects the overall aesthetics of the product, but also may reduce its durability.

[0032] In view of the above analysis, please refer to Figures 1 to 5 , the applicant proposes a key cover for covering the keyhole 51 on the faceplate 5 of a smart lock, which comprises a deformable annular body and a deformable connecting arm 4 connected to the outside of the deformable annular body; the deformable annular body is used to be embeddable in the keyhole 51, and the deformable connecting arm 4 is used to be limited in the fixing position 52 provided on the faceplate 5 to ensure that the key cover will not be separated from the faceplate after being opened, the deformable annular body of the key cover can be tightly fitted with the keyhole 51 on the faceplate 5, solving the gap and shaking problem between the key cover and the keyhole 51, and the overall aesthetics is better.

[0033] The key cover provided by the embodiment of the utility model includes deformable annular body and deformable connecting arm 4. The deformable annular body includes outer ring body 1 and center part 2, and the inside of outer ring body 1 is connected with the outside of center part 2, and a plurality of avoidance positions 3 are arranged along the circumferential direction at the connection position; the outer ring body 1 can be embedded in the keyhole 51, that is, the outer ring body 1 can be placed in the keyhole 51 to cover the keyhole 51; the center part 2 can be a sheet structure made of soft rubber material, and a plurality of through holes are arranged at the circumferential connection position of the outer ring body 1 and the center part 2 to form a plurality of avoidance positions 3. One end of the deformable connecting arm 4 is connected to the outside of the outer ring body 1, and the other end of the deformable connecting arm 4 is limited in the fixing position 52 provided on the faceplate 5.

[0034] In the embodiment, the fixing position 52 is used to ensure that the key cover will not be separated from the faceplate after being opened. The fixing position 52 can be a limiting through hole arranged on the faceplate, and the deformable connecting arm 4 is inserted into the limiting through hole for limiting. The fixing position 52 can also be an installation position matched with a fixing pin or the like, which is used to fix and install the deformable connecting arm 4 on the faceplate after being matched with the fixing pin or the like.

[0035] In this embodiment, the keyhole 51 is a stepped hole opened towards the inside of the panel, the aperture of the stepped hole is reduced towards the inside of the panel, and the outer ring body 1 is embedded in the large hole of the stepped hole. When it is necessary to open the key cover by using a mechanical key to unlock, the center part 2 is pressed and recessed into the small hole of the stepped hole, so that the part between the adjacent voids 3 (i.e. the connecting part between the center part 2 and the outer ring body 1) applies pressure to the inside of the small hole of the stepped hole. Since the outer ring body 1 is embedded in the large hole of the keyhole 51 and cannot enter the small hole of the stepped hole without deformation, when the outer ring body 1 is subjected to the pressure of recessing into the small hole of the stepped hole, the outer ring body 1 generates a counteracting force, which causes the outer peripheral part of the outer ring body 1 to be raised in the opposite direction of the recess and protrude above the panel 5, so that the deformable ring body can be easily pried out of the keyhole 51. After being pried out, the deformable connecting arm 4 is connected with the limiting position of the fixed position 52 to ensure that the key cover cannot fall off the panel 5.

[0036] In this embodiment, the deformable ring body is matched and adapted to the shape of the keyhole 51 on the panel 5. Through the interference fit between the deformable ring body and the keyhole 51, the gap and shaking problem between the key cover and the keyhole 51 is effectively solved, thereby improving the overall aesthetics.

[0037] In an embodiment, the outer ring body 1, the center part 2 and the deformable connecting arm 4 are integrally formed.

[0038] In this embodiment, the various components of the entire key cover are integrally formed and designed, ensuring that each part of the key cover is tightly connected and seamlessly connected, thereby avoiding the loosening and wear problems that may be caused by the traditional splicing method, and ensuring the stability and overall durability of the key cover.

[0039] The integrally formed setting also simplifies the production process and reduces the manufacturing cost; in addition, it is also convenient to install and replace, and the key cover can be easily installed on the panel 5 of the smart lock, or a new key cover can be quickly replaced when needed.

[0040] In an embodiment, the deformable ring body and the deformable connecting arm 4 are made of a rubber material with a rebound function.

[0041] In this embodiment, the rubber material can automatically recover to its original state after being deformed by external force, ensuring the stability and durability of the key cover during long-term use. In addition, the selection of the rubber material also has good impact resistance, which can effectively absorb the impact force that the key cover may receive during use, thereby prolonging the service life of the key cover.

[0042] Preferably, the rubber material can be made of materials such as silicone rubber, polyurethane elastomer and thermoplastic elastomer, which have functions such as high and low temperature resistance, stretch resistance and wear resistance.

[0043] Referring to Figure 1 and Figure 5 In an embodiment, a plurality of rib positions 11 are arranged on the outer side of the outer ring body 1 in the circumferential direction, and the rib positions 11 are used to achieve interference fit with the keyhole 51 when the outer ring body 1 is fitted into the keyhole 51.

[0044] In this embodiment, a plurality of rib positions 11 are designed and arranged on the outer side edge of the outer ring body 1 in the circumferential direction. The main function of these rib positions 11 is to achieve interference fit with the keyhole 51 during the process of fitting the outer ring body 1 into the keyhole 51, thereby ensuring the close combination between the two.

[0045] Specifically, in order to achieve better fitting effect, the number of the plurality of rib positions 11 can be the same as that of the plurality of avoidance positions 3, and the plurality of rib positions 11 and the plurality of avoidance positions 3 correspond to each other in the circumferential direction. After being extruded, the rib positions 11 press the circumferential two-side gaps and the avoidance positions 3 in the circumferential direction, so that the circumferential two-side gaps and the avoidance positions 3 are deformed, thereby generating sufficient friction and support force in the keyhole 51 to bind the outer ring body 1 from falling out of the keyhole 51.

[0046] More specifically, the specific number of rib positions 11 and avoidance positions 3 can be set according to actual needs, and the plurality of rib positions 11 and the plurality of avoidance positions 3 are equally distributed in the circumferential direction; and the side of each avoidance position 3 facing the circumferential outer side direction is designed as an arc-shaped side. Such design not only increases the beauty of the structure, but also effectively reduces stress concentration, improves overall durability and reliability. Through the ingenious design of this embodiment, the fitting between the outer ring body 1 and the keyhole 51 is more close, which ensures the stability and safety during use.

[0047] Referring to Figure 1 , Figure 2 and Figure 5 In an embodiment, the fixing position 52 is a limiting through hole, the deformable connecting arm 4 is in the shape of a strip, one end of the deformable connecting arm 4 is bent and arranged and connected on the outer periphery of the side of the outer ring body 1 facing the inside of the keyhole 51, the other end of the deformable connecting arm 4 is inserted into the fixing position 52, and a protruding part 41 is arranged on the outer wall of the deformable connecting arm 4 close to the other end, and the protruding part 41 is used to prevent the deformable connecting arm 4 from being pulled out of the fixing position 52.

[0048] In this embodiment, the protruding portion 41 is integrally designed with the deformable connecting arm 4 and adopts the same material, that is, the protruding portion 41 also adopts the rubber material with the rebound function, the outer diameter of the protruding portion 41 is greater than the hole diameter of the fixing position 52, the protruding portion 41 passes through the fixing position 52 in the form of interference extrusion, the distance from one end of the deformable connecting arm 4 to the protruding portion 41 is the distance that the deformable connecting arm 4 can be pulled out of the fixing position 52, which provides the corresponding operation space for avoiding the keyhole 51 when the key cover is opened, and also prevents the key cover from being pulled out of the panel 5 when the key cover is opened.

[0049] In some preferred embodiments, the protruding portion 41 can be a barb, the barb is arranged in a circumferential direction on the outer wall of the deformable connecting arm 4; the side of the barb facing the other end of the deformable connecting arm 4 is connected to the deformable connecting arm 4 in the form of an arc surface transition, which can facilitate the extrusion of the barb and make the barb more easily pass through the fixing position 52; the side of the barb facing one end of the deformable connecting arm 4 is connected to the deformable connecting arm 4 in the form of a plane, which can better be clamped in the fixing position 52 when the deformable connecting arm 4 is pulled outwards, so as to prevent the deformable connecting arm 4 from being pulled out of the fixing position 52.

[0050] The utility model embodiment further provides a kind of intelligent lock, including panel 5 and the key cover as described above, panel 5 is equipped with the keyhole 51 corresponding to the lock cylinder of intelligent lock and the fixing position 52 located below keyhole 51;The outer ring body 1 of key cover can be embedded in keyhole 51, the other end of the deformable connecting arm 4 of key cover is limited in the fixing position 52 set on panel 5.

[0051] In this embodiment, the position of the fixing position 52 is preferably set near or at the bottom region of the keyhole 51, so that when the key cover is opened, the key cover will be located below the keyhole 51, thereby conveniently leaving out space to adapt to the unlocking operation of the mechanical key, and facilitating the reinstallation of the key cover back into the keyhole 51.

[0052] In this embodiment, the fixing position 52 preferably adopts a limiting through hole for the other end of the deformable connecting arm 4 to pass in and out, and performs corresponding limiting when taken out to ensure that it will not be completely pulled out.

[0053] In an embodiment, the shape of the keyhole 51 and the outer ring body 1 is one of circular, oval and polygonal.

[0054] In this embodiment, the shape-adapted keyhole 51 and the outer ring body 1 can achieve closer cooperation, thereby improving the overall stability and security. In addition, the shape design of the keyhole 51 and the outer ring body 1 also considers the aesthetics, so that the appearance of the intelligent lock is more harmonious and unified.

[0055] Preferably, the shape of the keyhole 51 and the outer ring body 1 adopts a circular shape, which is more concise and generous in vision.
