Description

[0001] The present application relates to the technical field of locks, in particular to a key and an intelligent lock. BACKGROUND

[0002] In order to make the front side of the intelligent lock beautiful and have a certain anti-theft property, a mechanical keyhole is usually arranged between the handle and the outer panel of the lock. The handle is located in the direction in which the mechanical key is pulled out of the mechanical keyhole, thereby shielding the keyhole. In order to further increase the anti-theft property, the keyhole includes a transition hole and a key body hole arranged in sequence, and the mechanical key needs to be longer and can be inserted into the key body hole after passing through the transition hole.

[0003] However, the space between the handle and the outer panel of the lock is limited, and the length of the mechanical key should be less than the distance between the handle and the outer panel of the lock, so as to be able to enter between the handle and the outer panel of the lock and be inserted into the keyhole. This makes the length of the mechanical key only be able to be set within a limited range, thereby causing the length of the transition hole of the keyhole to be able to be set within a limited range, and the anti-theft property is general.

[0004] Therefore, how to solve or improve the problem that the length of the mechanical key of the intelligent lock is limited under the premise that the mechanical key can be inserted into the keyhole in the related technology has become an important technical problem to be solved by the person skilled in the art.

This makes the length of the guide hole also be arbitrarily set according to the requirement and is not limited, so that a longer guide hole can be set to increase the difficulty of the lock tool passing through the guide hole, thereby better preventing theft.

DETAILED DESCRIPTION

[0037] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings 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 those skilled in the art without creative work fall within the protection scope of the present application.

[0038] The embodiments of the present application will be described below with reference to the drawings. Figures 1 to 7 , the embodiments of the present application are described.

[0039] According to the embodiments of the present application, in one aspect, a key is provided, as shown in Figure 1 , comprising a key body 1 and at least two connecting pieces 2. The connecting pieces 2 are connected in sequence to form an entire extension. The key body 1 is connected with the connecting piece 2 at the head end, or the key body 1 is connected with the connecting piece 2 at the tail end.

[0040] As shown in Figure 2 and Figure 3As shown, the connecting piece 2 comprises a first bending part 21, a second bending part 22 and a third bending part 23. The opposite sides of the second bending part 22 are connected with the first bending part 21 and the third bending part 23 respectively. For every two adjacent connecting pieces 2, the first bending part 21 of the first connecting piece 2 is rotationally connected with the third bending part 23 of the second connecting piece 2, so that the connecting pieces 2 are connected in sequence to form the whole extension section.

[0041] For the whole extension section, any two adjacent connecting pieces 2 can be relatively rotated at the rotational connection to make the extension section bend at the rotational connection.

[0042] When using the key to open the lock, the extension section is bent so that the key body 1 can enter the space between the handle and the outer panel of the smart door lock in a parallel state with the keyhole. After aligning the key body 1 with the keyhole, the key body 1 is inserted into the guide hole of the keyhole. Then, by bending the extension section, a part of the extension section can be aligned with the keyhole in a parallel state, and the part is inserted into the guide hole of the keyhole.

[0043] In this way, the extension section is continuously bent so that the extension section gradually inserts into the guide hole of the keyhole. In this process, the key body 1 gradually passes through the guide hole and is inserted into the key body 1 hole of the keyhole. At this time, holding the part of the extension section located outside the keyhole can drive the key body 1 to rotate and open the lock.

[0044] Since the extension section of the key can gradually insert into the keyhole by continuously bending, the length of the extension section of the key can be arbitrarily set and is not limited by the distance between the handle and the outer panel. This makes the length of the guide hole also be arbitrarily set according to the needs and is not limited, so that a longer guide hole can be set to increase the difficulty of the lock picking tool passing through the guide hole, thereby better preventing theft.

[0045] The key body 1 can be rotationally connected with the connecting piece 2 located at the head end or the tail end. Since the extension section can be bent, as long as the distance between the handle and the outer panel is greater than the length of the key body 1, the key body 1 can enter the space between the handle and the outer panel of the smart door lock in a parallel state with the keyhole. Therefore, the distance between the handle and the outer panel can be set smaller to reduce the occupied space and also make the anti-theft performance better.

[0046] For each connecting piece 2, a straight plate can be bent by sheet metal during manufacturing. Specifically, the first side of the straight plate is bent to form the first bending part 21, the second side of the straight plate is reversely bent to form the third bending part 23, and the remaining part is the second bending part 22. Therefore, the first bending part 21 is located at the first side of the second bending part 22, and the third bending part 23 is located at the second side of the second bending part 22. The first side and the second side of the second bending part 22 are oppositely arranged.

[0047] This design allows for the formation of a first bend 21, a second bend 22, and a third bend 23 that are connected as one unit through a simple sheet metal process, thereby forming the connector 2. This makes manufacturing simpler and lower in cost.

[0048] As an optional implementation, the key also includes a pivot 3, the first bent portion 21 is plate-shaped and has a first pivot hole 211 along the thickness direction, and the third bent portion 23 is plate-shaped and has a second pivot hole 231 along the thickness direction.

[0049] Taking two adjacent connectors 2 as an example, such as Figure 4 and Figure 5 As shown, the first bent portion 21 of the first connector 2 and the third bent portion 23 of the second connector 2 overlap in the thickness direction, so that the first rotating hole 211 and the second rotating hole 231 are coaxially aligned. Then, a rotating shaft 3 is sequentially inserted into the first rotating hole 211 and the second rotating hole 231, allowing both the first bent portion 21 of the first connector 2 and the third bent portion 23 of the second connector 2 to rotate around the rotating shaft 3. Thus, the first bent portion 21 of the first connector 2 and the third bent portion 23 of the second connector 2 are rotatably connected.

[0050] In this way, the two connectors 2 can be rotatably connected by the rotating shaft 3, and both connectors 2 can rotate around the rotating shaft 3.

[0051] Similarly, each pair of adjacent connectors 2 can be rotated together to form the entire extension. With this configuration, both the first bend 21 and the third bend 23 are simple plate-shaped sections, requiring only simple openings, making the manufacturing process relatively simple.

[0052] As an optional embodiment, such as Figure 3 As shown, the first bent portion 21 formed by bending is located on the first side of the second bent portion 22, so that a first receiving space 221 is formed between the first bent portion 21 and the side of the first side of the second bent portion 22.

[0053] Similarly, the third bend 23 formed by bending is located on the second side of the second bend 22, so that a second receiving space 222 is formed between the third bend 23 and the side of the second bend 22.

[0054] Thus, taking two adjacent connectors 2 as an example, such as Figure 5As shown, the first bent portion 21 of the first connecting piece 2 extends into the second accommodating space 222 of the second connecting piece 2. At the same time, the third bent portion 23 of the second connecting piece 2 extends into the first accommodating space 221 of the first connecting piece 2. At this time, the first bent portion 21 of the first connecting piece 2 and the third bent portion 23 of the second connecting piece 2 overlap in the thickness direction, and the first rotation hole 211 and the second rotation hole 231 are coaxially aligned. The rotation shaft 3 is sequentially arranged in the first rotation hole 211 and the second rotation hole 231, and the complete rotatable connection is achieved.

[0055] Since the first accommodating space 221 accommodates the third bent portion 23 and the second accommodating space 222 accommodates the first bent portion 21, the thickness of the two connecting pieces 2 after the rotation connection is small, and the whole is more compact.

[0056] In an optional embodiment, as shown in Figure 2 and Figure 4 For each connecting piece 2, the first arc surface 233 is arranged at the end of the third bent portion 23 away from the second bent portion 22, and the first arc surface 233 is coaxial with the second rotation hole 231. When the connecting piece 2 rotates around the rotation shaft 3 arranged in the second rotation hole 231, the first arc surface 233 also rotates around the rotation shaft 3.

[0057] This makes that for the two adjacent connecting pieces 2, even if the third bent portion 23 of the first connecting piece 2 enters the first accommodating space 221 of the second connecting piece 2 more, and abuts against the second bent portion 22 of the second connecting piece 2. The existence of the first arc surface 233 can also make the third bent portion 23 rotate normally. Therefore, there is no need to leave a rotation space between the third bent portion 23 of the first connecting piece 2 and the second bent portion 22 of the second connecting piece 2, and the whole can be more compact.

[0058] Moreover, the first straight surface 232 is arranged at the end of the third bent portion 23 away from the second bent portion 22. The first straight surface 232 and the first arc surface 233 are sequentially arranged, and the first arc surface 233 can be a quarter arc.

[0059] For the two adjacent connecting pieces 2, the third bent portion 23 of the first connecting piece 2 enters the first accommodating space 221 of the second connecting piece 2, and after being rotationally connected with the first bent portion 21 of the second connecting piece 2, it can rotate normally when the first connecting piece 2 and the second connecting piece 2 rotate relatively in the direction of the position where the first arc surface 233 is located; when the first connecting piece 2 and the second connecting piece 2 rotate relatively in the direction of the position where the first straight surface 232 is located, the first straight surface 232 abuts against the second bent portion 22 of the second connecting piece 2, thereby limiting the rotation of the first connecting piece 2 and the second connecting piece 2 in this direction.

[0060] Make the extension section can only be folded in one direction, the operation is more simple, avoid the extension section random bending influence operation.

[0061] As an optional embodiment, as shown in Figure 2 and Figure 3 The connecting piece 2 also includes a fourth bending part 24, a fifth bending part 25 and a sixth bending part 26. The fifth bending part 25 is connected with the fourth bending part 24 and the sixth bending part 26 on opposite sides. For each adjacent two connecting pieces 2, the fourth bending part 24 of the first connecting piece 2 is rotationally connected with the sixth bending part 26 of the second connecting piece 2, and the first bending part 21 of the first connecting piece 2 is rotationally connected with the third bending part 23 of the second connecting piece 2. Thus, the connecting pieces 2 are sequentially connected end to end to form the entire extension section.

[0062] In this way, the adjacent two connecting pieces 2 are rotationally connected through the fourth bending part 24 and the sixth connecting part, and the first bending part 21 and the third bending part 23, which is more stable and reliable.

[0063] It is worth mentioning that the rotation centers of the fourth bending part 24 and the sixth connecting part and the rotation centers of the first bending part 21 and the third bending part 23 should be coaxial.

[0064] In an optional embodiment, the fourth bending part 24 is plate-shaped and has a third rotation hole 241 formed in the thickness direction, and the sixth bending part 26 is plate-shaped and has a fourth rotation hole 261 formed in the thickness direction.

[0065] Taking the adjacent two connecting pieces 2 as an example, as shown in Figure 4 and Figure 5 The first bending part 21 and the fourth bending part 24 of the first connecting piece 2 and the third bending part 23 and the sixth bending part 26 of the second connecting piece 2 are overlapped in the thickness direction. The first rotation hole 211, the second rotation hole 231, the third rotation hole 241 and the fourth rotation hole 261 are coaxially aligned. At this time, a rotation shaft 3 is sequentially arranged in the second rotation hole 231, the first rotation hole 211, the third rotation hole 241 and the fourth rotation hole 261. The first bending part 21 and the fourth bending part 24 of the first connecting piece 2 and the third bending part 23 and the sixth bending part 26 of the second connecting piece 2 can rotate around the rotation shaft 3. Thus, the first connecting piece 2 and the second connecting piece 2 are rotationally connected.

[0066] In this way, the fourth bending part 24 and the sixth bending part 26 are both simple plate-shaped, which only need to be simply drilled, and the manufacturing process is relatively simple.

[0067] In an alternative embodiment, another straight plate can be bent at the time of manufacture. Specifically, the first side of the straight plate is bent to form the fourth bent portion 24, and the second side of the straight plate is bent in the opposite direction to form the sixth bent portion 26, and the remaining part is the fifth bent portion 25. Thus, the fourth bent portion 24 is located on the first side of the fifth bent portion 25, and the sixth bent portion 26 is located on the second side of the fifth bent portion 25. The first side and the second side of the fifth bent portion 25 are opposite to each other.

[0068] In this way, the fourth bent portion 24, the fifth bent portion 25 and the sixth bent portion 26 are formed by a simple sheet metal process, and are combined with the first bent portion 21, the second bent portion 22 and the third bent portion 23 to form the connector 2.

[0069] The fourth bent portion 24 formed by bending is located on the first side of the fifth bent portion 25, so that the fourth bent portion 24 and the side surface on the first side of the fifth bent portion 25 form a third accommodating space 251.

[0070] Similarly, the sixth bent portion 26 formed by bending is located on the second side of the fifth bent portion 25, so that the sixth bent portion 26 and the side surface on the second side of the fifth bent portion 25 form a fourth accommodating space 252.

[0071] In this way, taking two adjacent connectors 2 as an example, the fourth bent portion 24 of the first connector 2 extends into the fourth accommodating space 252 of the second connector 2. At the same time, the sixth bent portion 26 of the second connector 2 extends into the third accommodating space 251 of the first connector 2. At this time, the fourth bent portion 24 of the first connector 2 and the sixth bent portion 26 of the second connector 2 overlap in the thickness direction, and the third through hole 241 and the fourth through hole 261 are coaxially aligned.

[0072] Since the third accommodating space 251 accommodates the sixth bent portion 26 and the fourth accommodating space 252 accommodates the fourth bent portion 24, the overall thickness of the two connectors 2 after rotation connection is smaller, so that the overall is more compact.

[0073] As an alternative embodiment, for each connector 2, as shown in Figure 2 and Figure 4 The end of the sixth bent portion 26 away from the fifth bent portion 25 is provided with a second arc surface 263, and the second arc surface 263 is coaxial with the second through hole 231. When the connector 2 rotates around the rotating shaft 3 passing through the second through hole 231, the second arc surface 263 also rotates around the rotating shaft 3.

[0074] This ensures that, for two adjacent connectors 2, even if more of the sixth bend 26 of the first connector 2 enters the third receiving space 251 of the second connector 2 and abuts against the fifth bend 25 of the second connector 2, the presence of the second arc surface 263 allows the sixth bend 26 to rotate normally. Therefore, there is no need to leave rotational space between the sixth bend 26 of the first connector 2 and the fifth bend 25 of the second connector 2, resulting in a more compact overall design.

[0075] Furthermore, a second straight surface 262 is provided at the end of the sixth bend 26 away from the fifth bend 25. The second straight surface 262 and the second arc surface 263 are provided sequentially, and the second arc surface 263 can be a quarter circle.

[0076] For two adjacent connectors 2, such as Figure 4 As shown, the sixth bend 26 of the first connector 2 enters the third receiving space 251 of the second connector 2 and is rotatably connected with the first bend 21 of the second connector 2. When the first connector 2 and the second connector 2 rotate relative to each other in the direction of the second arc surface 263, they can rotate normally. When the first connector 2 and the second connector 2 rotate relative to each other in the direction of the second straight surface 262, the second straight surface 262 abuts against the fifth bend 25 of the second connector 2, thereby restricting the first connector 2 and the second connector 2 from rotating in that direction.

[0077] This allows the extension section to bend in only one direction, making the operation simpler and preventing the extension section from bending arbitrarily and affecting the operation.

[0078] In some embodiments, for a connector 2, such as Figures 2 to 5 As shown, the end of the first bend 21 away from the second bend 22 is connected to the end of the fourth bend 24 away from the fifth bend 25 as a whole.

[0079] In this way, when manufacturing connector 2, a long straight plate can be bent using sheet metal bending. Specifically, the first and second sides of the long straight plate are bent to form the third bend 23 and the sixth bend 26, respectively. Then, the first and second sides of the remaining portion are bent in the opposite direction to form the second bend 22 and the fifth bend 25, respectively. Finally, the remaining portion is bent 180° from the middle to form the first bend 21 and the sixth bend 26, respectively. Thus, connector 2 is formed entirely by sheet metal bending, making manufacturing much simpler.

[0080] The second rotating hole 231 and the fourth rotating hole 261 can be formed by opening through the third bending part 23 and the sixth bending part 26, and the first rotating hole 211 and the third rotating hole 241 can be formed by opening through the first bending part 21 and the fourth bending part 24.

[0081] As an optional embodiment, as shown in Figure 1 The key further comprises a holding piece 4, which is connected with the connecting piece 2 at the head end and connects the key body 1 with the connecting piece 2 at the tail end. Alternatively, the holding piece 4 is connected with the connecting piece 2 at the tail end and connects the key body 1 with the connecting piece 2 at the head end.

[0082] In this way, by continuously bending the extension section composed of a plurality of connecting pieces 2 connected in turn, the extension section is gradually inserted into the guide hole of the keyhole, and the key body 1 is gradually inserted into the key body 1 hole of the keyhole after passing through the guide hole. At this time, the user can hold the holding piece 4 and apply force to rotate, and the rotating force is transmitted to the key body 1 through the extension section, so as to rotate the key body 1 to unlock, which is more convenient to operate.

[0083] The holding piece 4 can be block-shaped, and a hanging hole can be provided through the holding piece 4, so that the key can be hung on a key ring, a hook or other positions through the hanging hole, facilitating carrying and storage.

[0084] For the connection between the key body 1 and the connecting piece 2, as shown in Figure 1 and Figure 6 The key body 1 and the connecting piece 2 are rotatably connected. A fifth rotating hole 11 is formed in the key body 1, a part of the key body 1 is inserted between the third bending part 23 and the sixth bending part 26 of the connecting piece 2, so that the fifth rotating hole 11, the second rotating hole 231 and the fourth rotating hole 261 are coaxially aligned, and the rotating shaft 3 is sequentially inserted through the second rotating hole 231, the fifth rotating hole 11 and the fourth rotating hole 261, so as to rotatably connect the key body 1 and the connecting piece 2.

[0085] For the connection between the holding piece 4 and the connecting piece 2, as shown in Figure 1 and Figure 7 The holding piece 4 and the connecting piece 2 are rotatably connected. The holding piece 4 comprises a connecting plate 43 and first and second side plates 41 and 42 connected to both sides of the connecting plate 43 and arranged in parallel, and a sixth rotating hole 411 and a seventh rotating hole 421 are formed in the first and second side plates 41 and 42, respectively, and the first rotating hole 211 and the seventh rotating hole 421 are coaxial. The first and fourth connecting parts of the connecting piece 2 are inserted between the first and second side plates 41 and 42, so that the sixth rotating hole 411, the first rotating hole 211, the third rotating hole 241 and the seventh rotating hole 421 are coaxially aligned, and the rotating shaft 3 is sequentially inserted through the sixth rotating hole 411, the first rotating hole 211, the third rotating hole 241 and the seventh rotating hole 421, so as to rotatably connect the holding piece 4 and the connecting piece 2.

[0086] According to the embodiments of the present application, on the other hand, a smart lock is also provided, which comprises a smart lock and a mechanical key, and the mechanical key is set as any of the keys. The technical effects of the smart lock and the key are the same, and therefore will not be described again.

[0087] While embodiments of the present application have been described in conjunction with the appended drawings, various modifications and changes can be suggested by persons skilled in the art, and all such modifications and changes are believed to fall within the scope of the present application.
