[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0050] In the related art, an emergency lock cylinder that is opened by using a mechanical key exists in an intelligent lock. Since the frequency of use of the emergency lock cylinder is low, the keyhole needs to be blocked by using a key cover in most cases.

[0051] However, the key cover generally adopts the following schemes. One is a key cover with a soft glue tail. When used, the key cover is pried out of the keyhole and connected with the lock panel by using the soft glue tail to prevent the key cover from falling. This scheme is inconvenient to operate and affects the experience of a user. Another adopts a seesaw flip structure. That is, by pressing one end of the key cover, the other end of the key cover is lifted up and flipped by more than 90° to expose the lock cylinder, so as to facilitate unlocking. In this scheme, the opened key cover will interfere with the unlocking operation, affecting the unlocking operation and the experience of the user.

[0052] Therefore, the present application provides a rotary opening type key cover, a lock, and a door to solve or improve the problem of inconvenient user operation and poor experience in the unlocking process.

[0053] The embodiments of the present application will be described below in combination with Figures 1 to 11 .

[0054] According to the embodiments of the present application, in a first aspect, a rotary opening type key cover 1 is provided, as shown in Figure 1 and Figure 2 , which comprises a fixed seat 11, a first sliding cover 12, a second sliding cover 13, and a push plate 14.

[0055] The specific scheme is as follows, as shown in Figure 11 , the fixed seat 11 is adapted to be connected with the inner wall surface of the lock panel 2 by a screw, as shown in Figure 6 As shown, the fixing seat 11 is provided with a first through hole 111, which is suitable for opening and closing the lock with a key. Figure 1 and Figure 2 As shown, a guide portion 112 is provided on the fixing seat 11;

[0056] The first sliding cover 12 is limited by the guide portion 112 and can be reciprocated and slidably disposed on the fixed base 11 along the first direction; the second sliding cover 13 is limited by the guide portion 112 and can be reciprocated and slidably disposed on the fixed base 11 along the first direction;

[0057] The push plate 14 is provided with a second through hole 141 and a first driving portion 142 . The first driving portion 142 is adapted to be located in the key hole 21 on the lock panel 2 . The second through hole 141 is coaxially arranged with the first through hole 111 .

[0058] Among them, such as Figure 4 and Figure 5 As shown, the first driving part 142 drives the push plate 14 to rotate around the axis of the keyhole 21. The push plate 14 can drive the first sliding cover 12 and the second sliding cover 13 to slide toward or away from each other through the second driving part 15 and the third driving part 16 to cover or expose the first through hole 111.

[0059] It should be noted that the first direction is a direction perpendicular to the axis of the keyhole 21 , that is, any direction perpendicular to the axis of the keyhole 21 can be the first direction. Preferably, the first direction coincides with the length direction of the lock panel 2 .

[0060] It needs to be explained that “a first through hole 111 is provided on the fixing seat 11, which is suitable for the key to open and close the lock”, there are two situations. Situation 1: the key passes through the first through hole 111 and enters the lock core to open and close the lock; Situation 2: a part of the lock core is coaxially arranged in the first through hole 111, which is convenient for the key to open and close the lock.

[0061] In the specific use process, such as Figure 1 As shown, when the smart lock has no power and needs to be unlocked with a key in an emergency, the first driving part 142 located in the keyhole 21 on the lock panel 2 is turned to rotate the push plate 14 around the axis of the keyhole 21, and the first sliding cover 12 and the second sliding cover 13 are driven to slide back to each other through the second driving part 15 and the third driving part 16 respectively, thereby exposing the first through hole 111, which is convenient for the key to be inserted to open and close the lock; Figure 2 As shown, after unlocking is completed, the first driving portion 142 is reversely shifted to rotate the push plate 14 in the opposite direction, thereby driving the first sliding cover 12 and the second sliding cover 13 to slide toward each other to cover the first through hole 111 .

[0062] In this embodiment, Figure 1 and Figure 2As shown, the lock core can be covered or exposed by only moving the first driving part 142 on the push plate 14. The operation is convenient and does not interfere with the unlocking action of the key, thereby improving the user experience. At the same time, the rotary opening key cover 1 in this application is embedded in the lock panel 2, which can improve the aesthetics of the lock.

[0063] In one embodiment, Figure 1 and Figure 2 As shown, the second driving portion 15 includes a first driving pin 151 and a first driving slot 152. The first driving pin 151 is provided on the first sliding cover 12. Specifically, the first driving pin 151 and the first sliding cover 12 are integrally formed. The first driving slot 152 is provided on the push plate 14.

[0064] The third driving portion 16 includes a second driving pin 161 and a second driving slot 162. The second driving pin 161 is provided on the second sliding cover 13. Specifically, the second driving pin 161 and the second sliding cover 13 are integrally formed. The second driving slot 162 is provided on the push plate 14.

[0065] The first driving groove 152 and the second driving groove 162 extend along two opposite tangential directions of the keyhole 21 respectively, and are centrally symmetrically arranged around the axis of the keyhole 21 .

[0066] It should be noted that, in “the first drive groove 152 and the second drive groove 162 extend along two opposite tangential directions of the keyhole 21 respectively”, the extension direction of the first drive groove 152 and the direction of the second drive groove 162 are opposite, and can be two completely opposite directions, that is, the angle between the two directions is 180°, or the extension direction of the first drive groove 152 and the direction of the second drive groove 162 are opposite at a certain angle, that is: 160°≤α<180°, where α is the angle between the extension direction of the first drive groove 152 and the extension direction of the second drive groove 162.

[0067] In this embodiment, Figure 1 and Figure 2 As shown, by setting the first drive groove 152 and the second drive groove 162 on the push plate 14, the first drive groove 152 and the second drive groove 162 extend along two opposite tangential directions of the keyhole 21 respectively, and are centrally symmetrically arranged around the axis of the keyhole 21, and the first sliding cover 12 and the second sliding cover 13 are guided by the guide part 112, so that the first sliding cover 12 and the second sliding cover 13 can be synchronously driven to slide toward or away from each other by rotating the push plate 14, so as to realize the covering and opening of the first through hole 111. The structure is simple and can reduce the occupied space.

[0068] In some unillustrated embodiments, not shown in the figures, the second driving portion 15 includes a first driving pin 151 and a first driving slot 152, the first driving pin 151 is arranged on the push plate 14, and the first driving slot 152 is arranged on the first sliding cover 12; the third driving portion 16 includes a second driving pin 161 and a second driving slot 162, the second driving pin 161 is arranged on the push plate 14, and the second driving slot 162 is arranged on the second sliding cover 13; wherein, the first driving slot 152 and the second driving slot 162 extend respectively in directions perpendicular to the first direction.

[0069] In one embodiment, Figure 7 As shown, the first driving groove 152 includes a first arc segment 1521 and a first straight segment 1522 that are tangentially connected, and the axis of the first arc segment 1521 coincides with the axis of the keyhole 21;

[0070] and / or, such as Figure 7 As shown, the second driving groove 162 includes a second arc segment 1621 and a second straight segment 1622 that are tangentially connected to each other, and the axis of the second arc segment 1621 coincides with the axis of the keyhole 21 .

[0071] It should be noted that the above-mentioned “tangential connection” is explained by taking the first driving groove 152 as an example. The first straight line segment 1522 is connected to one end of the first arc segment 1521, and the first straight line segment 1522 extends along the tangent direction of the end portion of the first arc segment 1521 that is connected to the first straight line segment 1522.

[0072] In this embodiment, Figure 7 As shown, by setting a first arc segment 1521 on the first driving groove 152 and a second arc segment 1621 on the second driving groove 162, not only can the rotation and start of the push plate 14 be facilitated when the first through hole 111 is opened, the starting operating force of the push plate 14 can be reduced, the operating experience can be improved, and jamming can be prevented, and the push plate 14 cannot be started; it can also be self-locked when the first through hole 111 is closed, to prevent the push plate 14 from being driven to rotate due to the self-gravity of the first slide plate or the second slide plate, thereby exposing the first through hole 111.

[0073] In one embodiment, Figure 6 As shown, the guide portion 112 is a sliding groove extending along the first direction, and the first sliding cover 12 and the second sliding cover 13 can both slide back and forth in the sliding groove.

[0074] In this embodiment, the width of the slide groove is adapted to the width of the first slide cover 12 and the width of the second slide cover 13, which can ensure that the first slide cover 12 and the second slide cover 13 slide back and forth in the slide groove, and limit the first slide cover 12 along its width direction, and limit the second slide cover 13 along its width direction, thereby ensuring the stability of the first slide cover 12 and the second slide cover 13 sliding along the first direction.

[0075] In one embodiment, Figures 1 to 3 As shown, a plurality of limiting columns 113 are provided on the fixing seat 11, a first limiting groove 121 is provided on the first sliding cover 12, the first limiting groove 121 extends along the first direction, and the first limiting groove 121 is slidably connected to a limiting column 113, and a second limiting groove 131 is provided on the second sliding cover 13, the second limiting groove 131 extends along the first direction, and the second limiting groove 131 is slidably connected to a limiting column 113.

[0076] Specifically, the fixing base 11 is a plastic part, and the limiting column 113 and the fixing base 11 are an integrally formed structure; the first sliding cover 12 and the second sliding cover 13 are both plastic parts.
