Description

Technical Field

[0001] This application relates to the field of lock technology, and in particular to a smart lock. Background Technology

[0002] A smart lock is a more intelligent lock device in terms of user identification, security, manageability, and convenience; it is the locking component in an access control system. Most existing smart locks consist of a lock body, a lock cylinder, and a door panel, with the lock cylinder located in the lock body and connected to the door panel. However, when installing such smart locks on a door, the lock cylinder must be installed directly opposite the door panel, increasing the difficulty of installation. Summary of the Invention

[0003] This application provides a smart lock to solve the technical problem that when existing smart locks are installed on a door, the lock cylinder must be installed directly opposite the door panel, which increases the difficulty of installing the smart lock.

[0004] To address the aforementioned technical problems, this application proposes an intelligent lock for installation on a door, comprising: a lock body, including a first end face and a second end face arranged opposite to each other; a lock cylinder, including a lock cylinder body and a lock cylinder rod, the lock cylinder body being connected to the lock body, and the lock cylinder rod rotating at one end of the lock cylinder body near the second end face; and a door panel, including a door panel body, a knob, and a lock cylinder shaft, the knob being rotatably connected to one side of the door panel body, the lock cylinder shaft rotating around the knob and located on the other side of the door panel body, and the lock cylinder rod being inserted into the lock cylinder shaft; wherein the door panel is offset relative to the lock body.

[0005] The lock panel also includes a lock cylinder cover, which is connected to the end of the knob facing the lock cylinder. The lock cylinder rotates on the lock cylinder cover through a spherical structure.

[0006] The spherical structure includes a spherical space and a spherical part. The spherical space is formed between the inside of the lock cylinder shaft cover and the knob located on the other side of the lock door panel body. The spherical part is located at the end of the lock cylinder shaft away from the lock cylinder rod and rotates in the spherical space.

[0007] The spherical space includes a first spherical space and a second spherical space connected to the first spherical space. The first spherical space is provided inside the lock cylinder cover, and the second spherical space is provided at the end of the knob facing the lock cylinder cover. The spherical part includes a first spherical part and a second spherical part connected to the first spherical part. The first spherical part rotates within the first spherical space, and the second spherical part rotates within the second spherical space.

[0008] Wherein, at least one side of the upper and / or lower part of the first spherical part is provided with a first spherical limiting surface extending along the first direction; the lock cylinder shaft cover is provided with a first shaft cover limiting surface extending along the first direction, the number of first shaft cover limiting surfaces corresponds to the number of first spherical limiting surfaces, and the first spherical limiting surface and the corresponding first shaft cover limiting surface can be released to abut; wherein, the first direction is perpendicular to the door surface.

[0009] The first spherical part has a recessed portion on the left and / or right side, and the bottom wall of the recessed portion is a second spherical limiting surface; the lock cylinder cover has at least one limiting portion inside along the first direction, the limiting portion including a second shaft cover limiting surface, the number of second shaft cover limiting surfaces corresponding to the number of second spherical limiting surfaces, and the second spherical limiting surface and the corresponding second shaft cover limiting surface can be released from contact; wherein the second shaft cover limiting surface extends along the first direction.

[0010] The upper and / or lower ends of the limiting part are provided with a first shaft cover limiting surface; and / or, the limiting part is provided with a mounting hole, and the limiting part is connected to the knob part through the mounting hole.

[0011] Wherein, the upward rotation angle of the lock cylinder shaft relative to the lock cylinder shaft cover in the first direction is greater than or equal to 8 degrees and less than or equal to 15 degrees; the downward rotation angle of the lock cylinder shaft relative to the lock cylinder shaft cover in the first direction is greater than or equal to -15 degrees and less than or equal to -8 degrees; wherein the first direction is perpendicular to the door surface; and / or, the rightward rotation angle of the lock cylinder shaft relative to the lock cylinder shaft cover in the first direction is greater than or equal to 8 degrees and less than or equal to 15 degrees, and the leftward rotation angle of the lock cylinder shaft relative to the lock cylinder shaft cover in the first direction is greater than or equal to -15 degrees and less than or equal to -8 degrees.

[0012] The lock cylinder also includes a swing shaft, which is located inside the lock cylinder body and perpendicular to the extension direction of the lock cylinder body. A lock cylinder hole is provided at one end of the lock cylinder rod near the lock cylinder body. The lock cylinder rod is sleeved on the swing shaft through the lock cylinder hole. The lock cylinder hole and the swing shaft are clearance-fitted so that the lock cylinder rod can rotate within the lock cylinder body.

[0013] The lock cylinder body has a groove at one end facing the lock door panel, the swing shaft is located in the groove, and the different side walls of the groove limit the rotation angle of the lock cylinder rod.

[0014] The positional offset distance between the lock panel and the lock body is greater than or equal to 6mm and less than or equal to 15mm.

[0015] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a smart lock. The smart lock is used for installation on a door. The smart lock includes a lock body, a lock cylinder, and a door panel. The lock body includes a first end face and a second end face arranged opposite to each other. The lock cylinder includes a lock cylinder body and a lock cylinder rod. The lock cylinder body is connected to the lock body. The lock cylinder rod rotates to one end of the lock cylinder body near the second end face. The door panel includes a door panel body, a knob, and a lock cylinder shaft. The knob is rotatably connected to one side of the door panel body. The lock cylinder shaft rotates to the knob and is located on the other side of the door panel body. The lock cylinder rod is inserted into the lock cylinder shaft. The door panel is offset relative to the lock body.

[0016] Through the cooperation of the lock body, lock cylinder body, lock cylinder rod, lock door panel body, knob, and lock cylinder shaft, the lock cylinder and lock cylinder shaft simultaneously possess a certain amount of movement, thereby allowing the lock door panel to shift relative to the lock body. When the smart lock is installed on the door, because the lock cylinder rod and lock cylinder shaft can offset themselves through their own degrees of freedom, the lock cylinder does not need to be directly aligned with the lock door panel, thus reducing the difficulty of smart lock assembly and improving assembly efficiency.

Detailed Implementation

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] The smart lock provided by the present invention will be described in detail below with reference to embodiments. Please refer to... Figure 1 , Figure 2 , Figure 3 as well as Figure 4 , Figure 1 This is a top view of the smart lock in this application installed off-center; Figure 2 This is a schematic diagram of the lock body and lock cylinder structure in one embodiment of the smart lock of this application; Figure 3 This is a schematic diagram of the lock panel structure in one embodiment of the smart lock of this application; Figure 4 yes Figure 3The diagram shows the structure of A. This application provides a smart lock. The smart lock 10 is used to install on a door 20 to close and open the door 20 relative to the door frame 30. The smart lock 10 includes a lock body 11, a lock cylinder 12, and a lock panel 13. The lock body 11 includes a first end face 11a and a second end face 11b arranged opposite to each other. The lock cylinder 12 includes a lock cylinder body 121 and a lock cylinder rod 122. The lock cylinder body 121 is connected to the lock body 11. The lock cylinder body 121 is detachably connected to the lock body 11. The detachable connection can be, but is not limited to, plugging and snapping. The lock cylinder rod 122 rotates at the end of the lock cylinder body 121 near the second end face 11b. The lock cylinder rod 122 can rotate at any angle around the end of the lock cylinder body 121 near the second end face 11b, that is, the lock cylinder rod 122 deviates through its own degrees of freedom. The lock cylinder rod 122 and the end of the lock cylinder body 121 near the second end face 11b can be connected by means of, but not limited to, hinge structure, spherical structure 135, clearance fit, etc., so that the lock cylinder rod 122 can rotate at the end of the lock cylinder body 121 near the second end face 11b.

[0040] The lock panel 13 includes a lock panel body 131, a knob 132, and a lock cylinder 133. The lock panel 13 can be located indoors. The knob 132 is rotatably connected to one side of the lock panel body 131. The knob 132 can rotate relative to one side of the lock panel body 131, such as rotating clockwise or counterclockwise. The lock cylinder 133 rotates relative to the knob 132, meaning it is offset by its own degree of freedom. The lock cylinder 133 and the knob 132 can be connected by, but not limited to, a hinge structure (not shown in the figure), a spherical structure 135, or a clearance fit (not shown in the figure), so that the lock cylinder 133 can rotate relative to the knob 132. When the lock cylinder 133 rotates relative to the knob 132, the lock cylinder 133 is located on the other side of the lock panel body 131. The lock cylinder rod 122 is inserted into the lock cylinder shaft 133, so that the lock cylinder rod 122 and the lock cylinder shaft 133 are interconnected. The lock door panel 13 is offset relative to the lock body 11. Both the lock cylinder rod 122 and the lock cylinder shaft 133 can be installed with offset by their own degrees of freedom. If the lock body 11 and the lock cylinder 12 are fixed in position, the lock door panel 13 can be offset relative to the lock body 11 by a certain distance in any direction, such as to achieve a positional offset of the lock door panel 13 relative to the lock body 11.

[0041] Through the cooperation between the lock body 11, lock cylinder body 121, lock cylinder rod 122, lock door panel body 131, knob 132, and lock cylinder shaft 133, the lock cylinder 12 and lock cylinder shaft 133 simultaneously have a certain amount of movement, thereby allowing the lock door panel 13 to offset relative to the lock body 11. When the smart lock 10 is installed on the door body 20, because the lock cylinder rod 122 and lock cylinder shaft 133 can be offset by their own degrees of freedom, the lock cylinder 12 does not need to be installed directly opposite the lock door panel 13, thereby reducing the assembly difficulty of the smart lock 10 and improving the assembly efficiency of the smart lock 10.

[0042] Please see Figure 5 , Figure 6 as well as Figure 7 , Figure 5 This is a partial schematic diagram of an embodiment of the smart lock of this application; Figure 6 This is a partial cross-sectional schematic diagram of an embodiment of the smart lock of this application; Figure 7 yes Figure 6 The structural diagram of B shown is illustrated. (Combined with...) Figures 1 to 4 In some embodiments, the lock panel 13 further includes a lock cylinder shaft cover 134. The lock cylinder shaft cover 134 is connected to the end of the knob 132 facing the lock cylinder shaft 133. The lock cylinder shaft 133 is detachably connected to the end of the knob 132 facing the lock cylinder shaft 133. The detachable connection can be, but is not limited to, plug-in, snap-fit, and bolt connection. The lock cylinder shaft 133 rotates relative to the lock cylinder shaft cover 134 via a spherical structure 135, allowing the lock cylinder shaft 133 to rotate relative to the knob 132. By providing the aforementioned spherical structure 135 between the lock cylinder shaft cover 134 and the lock cylinder shaft 133, not only can the lock cylinder shaft 133 rotate relative to the lock cylinder shaft cover 134 and the knob 132, but the ease of rotation of the lock cylinder shaft 133 is also improved, thus facilitating operation; it also saves effort, has a simple structure, and is easy to assemble.

[0043] The aforementioned spherical structure 135 can be of any structure and is not limited herein. In one specific embodiment, the spherical structure 135 includes a spherical space 1351 and a spherical portion 1352. The aforementioned spherical space 1351 is formed between the interior of the lock cylinder cover 134 and the knob 132 located on the other side of the lock door panel body 131. Specifically, at least a portion of the spherical space 1351 is provided inside the lock cylinder cover 134, and at least a portion of the spherical space 1351 is also provided on the other side of the lock door panel body 131 for the knob 132.

[0044] A spherical portion 1352 is disposed at the end of the lock cylinder shaft 133 opposite to the lock cylinder rod 122. The spherical portion 1352 is detachably or fixedly connected to the end of the lock cylinder shaft 133 opposite to the lock cylinder rod 122. In this embodiment, the spherical portion 1352 is integrally formed with the lock cylinder shaft 133. The spherical portion 1352 rotates within the spherical space 1351, meaning that the spherical portion 1352 is at least partially in spherical contact with the spherical space 1351. During the rotation of the spherical portion 1352 within the spherical space 1351, the lock cylinder shaft 133 can rotate relative to the lock cylinder shaft cover 134.

[0045] The combination of the lock cylinder cover 134 and the knob 132 forms a spherical space 1351, which provides a degree of mobility. The lock cylinder 133 can rotate slightly within this spherical space 1351, providing a certain amount of movement. The lock cylinder 133 can rotate in any direction, without limitation. Furthermore, the spherical space 1351 and the spherical part 1352 work together to facilitate the rotation of the lock cylinder 133 around the lock cylinder cover 134; it is labor-saving, structurally simple, and easy to implement; and it also saves space.

[0046] Please see Figure 8 , Figure 9 and Figure 10 , Figure 8 This is a partial explosion diagram of an embodiment of the smart lock in this application; Figure 9 This is a schematic diagram of the structure of the lock cylinder shaft cover in one embodiment of the smart lock of this application;

[0047] Figure 10 This is a structural schematic diagram of the lock cylinder shaft and spherical portion in one embodiment of the smart lock of this application. (Combined with...) Figures 1 to 7 Specifically, the spherical space 1351 includes a first spherical space 13511 and a second spherical space 13512. The first spherical space 13511 and the second spherical space 13512 are connected. Both the first spherical space 13511 and the second spherical space 13512 include at least a portion of a sphere. The first spherical space 13511 is provided inside the lock cylinder cover 134. The first spherical space 13511 is used to accommodate at least a portion of the spherical portion 1352. The second spherical space 13512 is provided at one end of the knob 132 facing the lock cylinder cover 134. The second spherical portion 13522 can be used to accommodate at least a portion of the spherical portion 1352. The knob 132 is recessed at one end facing the lock cylinder cover 134 to form the second spherical space 13512.

[0048] The spherical portion 1352 includes a first spherical surface portion 13521 and a second spherical surface portion 13522. The first spherical surface portion 13521 and the second spherical surface portion 13522 are connected. The first spherical surface portion 13521 and the second spherical surface portion 13522 are detachably or fixedly connected. In this embodiment, the first spherical surface portion 13521 and the second spherical surface portion 13522 are integrally formed and connected. The first spherical surface portion 13521 rotates within a first spherical space 13511. The first spherical space 13511 is capable of accommodating the first spherical surface portion 13521. When the first spherical surface portion 13521 rotates within the first spherical space 13511, at least partially contacting at least a portion of the spherical surface of the first spherical space 13511. The second spherical surface portion 13522 rotates within a second spherical space 13512. The second spherical space 13512 is capable of accommodating the second spherical surface portion 13522. When the second spherical surface 13522 rotates in the second spherical space 13512, the second spherical surface 13522 is at least partially in contact with at least a portion of the spherical surface of the second spherical space 13512.

[0049] By dividing the spherical space 1351 into a first spherical space 13511 and a second spherical space 13512, and dividing the spherical portion 1352 into a first spherical portion 13521 and a second spherical portion 13522, not only can the lock cylinder shaft 133 rotate within the lock cylinder shaft cover 134, but it can also save space and reduce space occupation; in addition, it can also improve the stability of the lock cylinder shaft 133 connected within the lock cylinder shaft cover 134.

[0050] Furthermore, the aforementioned first spherical space 1351 is a first hemispherical space (not shown in the figure), meaning the first hemispherical space is half of a spherical space 1351. The second spherical space 1351 is a second hemispherical space (not shown in the figure), meaning the second hemispherical space is the other half of another spherical space 1351. The radii of the spherical spaces 1351 and 1351 are different. The first spherical surface 13521 is a first hemispherical portion, meaning the first hemispherical portion is half of a spherical portion 1352. The second spherical surface 13522 is a second hemispherical portion, meaning the second hemispherical portion is half of another spherical portion 1352. The radii of the spherical portion 1352 and 1352 are different.

[0051] Furthermore, the centers of the first spherical space 1351 and the second spherical space 1351 are concentrically arranged. The radius of the first spherical space 1351 is larger than the radius of the second spherical space 1351. For example, the radius of the first spherical space 1351 is twice the radius of the second spherical space 1351. Similarly, the centers of the first spherical surface 13521 and the second spherical surface 13522 are concentrically arranged, and the radius of the first spherical surface 13521 is larger than the radius of the second spherical surface 13522. For example, the radius of the first spherical surface 13521 is twice the radius of the second spherical surface 13522.

[0052] In addition, the spherical portion 1352 also includes a spherical connecting portion 13526. The spherical connecting portion 13526 is disposed between the first spherical portion 13521 and the second spherical portion 13522. As in this embodiment, the spherical connecting portion 13526 is integrally formed between the first spherical portion 13521 and the second spherical portion 13522. By providing the aforementioned spherical connecting portion 13526, the overall strength of the spherical portion 1352 can be improved, and the risk of breakage between the first spherical portion 13521 and the second spherical portion 13522 can also be reduced.

[0053] In some embodiments, the offset of the lock panel 13 relative to the lock body 11 needs to meet the actual installation conditions and is not an unlimited offset. Therefore, the degrees of freedom of the lock cylinder rod 122 and the lock cylinder shaft 133 in the smart lock 10 can be limited by setting a limiting structure (not shown in the figure), thereby limiting the rotation angle of the lock cylinder rod 122 and the rotation angle of the lock cylinder shaft 133, etc.

[0054] Continue reading Figures 1 to 10 In some embodiments, at least one side of the upper and / or lower portion of the first spherical surface 13521 is provided with a first spherical limiting surface 13523 extending along the first direction X. The first spherical limiting surface 13523 may, but is not limited to, be provided on one, two, three, or all four of the following: one side of the upper portion of the first spherical surface 13521, another side of the upper portion of the first spherical surface 13521, one side of the lower portion of the first spherical surface 13521, and another side of the lower portion of the first spherical surface 13521. The lock cylinder shaft cover 134 is internally provided with a first shaft cover limiting surface 13411 extending along the first direction X. The number of first shaft cover limiting surfaces 13411 corresponds to the number of first spherical limiting surfaces 13523. For example, the number of both first shaft cover limiting surfaces 13411 and first spherical limiting surfaces 13523 may be, but is not limited to, one, two, three, or four.

[0055] The first spherical limiting surface 13523 and the corresponding first shaft cover limiting surface 13411 can be disengaged from each other. Specifically, the first spherical limiting surface 13523 abuts against the corresponding first shaft cover limiting surface 13411; or, the first spherical limiting surface 13523 and the corresponding first shaft cover limiting surface 13411 are disengaged. When the lock cylinder shaft 133 is not rotated on the lock cylinder shaft cover 134, the first spherical limiting surface 13523 and the corresponding first shaft cover limiting surface 13411 are in a non-abutting state. The aforementioned first direction X can be, but is not limited to, a direction perpendicular to the surface of the door body 20.

[0056] By cooperating with the first spherical limiting surface 13523 in the first spherical part 13521 and the first shaft cover limiting surface 13411 in the lock cylinder shaft cover 134, the degree of freedom and rotation angle of the lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X can be limited.

[0057] In this embodiment, the upper and lower sides of the first spherical surface 13521 are each provided with a first spherical limiting surface 13523 extending along the first direction X. The lock cylinder shaft cover 134 is provided with a first shaft cover limiting surface 13411 extending along the first direction X inside. There are four first shaft cover limiting surfaces 13411 and four first spherical limiting surfaces 13523.

[0058] Four first shaft cover limiting surfaces 13411 are horizontally arranged. When the spherical part 1352 rotates upward along the first direction X, the first spherical limiting surfaces 13523 on the lower two sides of the first spherical part 13521 abut against the corresponding two first shaft cover limiting surfaces 13411. When the spherical part 1352 rotates downward along the first direction X, the first spherical limiting surfaces 13523 on the upper two sides of the first spherical part 13521 abut against the corresponding two first shaft cover limiting surfaces 13411. Through the cooperation of the four first shaft cover limiting surfaces 13411 and the four first spherical limiting surfaces 13523, the rotation angle of the lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X can be limited simultaneously. The rotation angle limited by the first spherical limiting surfaces 13523 and the first shaft cover limiting surfaces 13411 can be determined according to its own structure and is not limited here.

[0059] In some embodiments, recesses 13524 are provided on the left and / or right sides of the first spherical portion 13521. The recesses 13524 may, but are not limited to, be located on one or both of the left and right sides of the first spherical portion 13521. The bottom wall of the recess 13524 is a second spherical limiting surface 13525. At least one limiting portion 1341 is provided inside the lock cylinder cover 134 along the first direction X. The number of limiting portions 1341 may be, but is not limited to, one, two, or three. The limiting portion 1341 includes a second cylinder cover limiting surface 13412. The number of second spherical limiting surfaces 13525 and second cylinder cover limiting surfaces 13412 corresponds. The second spherical limiting surface 13525 and the corresponding second cylinder cover limiting surface 13412 are releasably abutted. When the lock cylinder shaft 133 is not rotated on the lock cylinder shaft cover 134, the second spherical limiting surface 13525 and the corresponding second shaft cover limiting surface 13412 are in a non-abutting state. When the lock cylinder shaft 133 rotates on the lock cylinder shaft cover 134, the second spherical limiting surface 13525 and the corresponding second shaft cover limiting surface 13412 abut against each other.

[0060] By cooperating with the second spherical limiting surface 13525 of the first spherical part 13521 and the second shaft cover limiting surface 13412 inside the lock cylinder shaft cover 134, the lock cylinder shaft 133 can achieve the degree of freedom of left and right movement and rotation angle relative to the lock cylinder shaft cover 134 in the first direction X.

[0061] In this embodiment, a second spherical limiting surface 13525 is provided on both the left and right sides of the first spherical part 13521. There are two second spherical limiting surfaces 13525. Two limiting portions 1341 are provided inside the lock cylinder cover 134 along the first direction X. Two second cylinder cover limiting surfaces 13412 of the two limiting portions 1341 are arranged opposite to each other. When the lock cylinder shaft 133 rotates to the left relative to the lock cylinder cover 134 along the first direction X, the second spherical limiting surface 13525 on the left side of the first spherical part 13521 abuts against the second cylinder cover limiting surface 13412 on the left side inside the lock cylinder cover 134, thereby limiting the rotation of the lock cylinder shaft 133 to the left relative to the lock cylinder cover 134 along the first direction X by the rotation angle of the lock cylinder cover 134. When the lock cylinder shaft 133 rotates to the right relative to the lock cylinder shaft cover 134 in the first direction X, the second spherical limiting surface 13525 on the right side of the first spherical surface 13521 abuts against the second shaft cover limiting surface 13412 on the right side inside the lock cylinder shaft cover 134, thereby limiting the rotation of the lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X to the rotation angle of the lock cylinder shaft cover 134.

[0062] In some embodiments, a first shaft cover limiting surface 13411 is provided at the upper end and / or lower end of the limiting portion 1341. For example, the first shaft cover limiting surface 13411 may be provided at the upper end of the limiting portion 1341; or, the first shaft cover limiting surface 13411 may be provided at the lower end of the limiting portion 1341; or, both the upper and lower ends of the limiting portion 1341 may be provided with the first shaft cover limiting surface 13411. By providing the first shaft cover limiting surface 13411 on the limiting portion 1341, not only is the internal structure of the lock cylinder shaft cover 134 simplified and easier to form, but installation space can also be saved. The positional relationship and number of the limiting portion 1341 and the first shaft cover limiting surface 13411 are not limited here.

[0063] In this embodiment, two limiting portions 1341 are symmetrically arranged inside the lock cylinder shaft cover 134 along the first direction X. The first shaft cover limiting surface 13411 is provided at both the upper and lower ends of one limiting portion 1341. The first shaft cover limiting surface 13411 is provided at both the upper and lower ends of the other limiting portion 1341.

[0064] Continue reading Figures 1 to 10 In some embodiments, the limiting part 1341 is provided with a mounting hole 13413. The limiting part 1341 is connected to the knob 132 through the mounting hole 13413. By providing the mounting hole 13413 on the limiting part 1341, a detachable connection is achieved between the limiting part 1341 and the knob 132. When the knob 132 rotates, the lock cylinder cover 134 also rotates with the knob 132. When there are two limiting parts 1341, each of the two limiting parts 1341 is provided with a mounting hole 13413. By installing the two limiting parts 1341 on the knob 132, the stability of the lock cylinder cover 134 installed on the knob 132 is improved.

[0065] The aforementioned limiting portion 1341 is provided with a second shaft cover limiting surface 13412, a first shaft cover limiting surface 13411, and a mounting hole 13413. By integrating the second shaft cover limiting surface 13412, the first shaft cover limiting surface 13411, and the mounting hole 13413 onto the limiting portion 1341, not only is the internal structure of the lock cylinder shaft cover 134 simplified and easier to form, but installation space is also saved; at the same time, the stability of the lock cylinder shaft cover 134 installed on the knob part 132 is also improved.

[0066] Specifically, when the limiting part 1341 includes both the first shaft cover limiting surface 13411 and the second shaft cover limiting surface 13412, the first shaft cover limiting surface 13411 and the second shaft cover limiting surface 13412 are arranged perpendicularly.

[0067] In some embodiments, the lock cylinder shaft 133 rotates upward relative to the lock cylinder shaft cover 134 in the first direction X by an angle greater than or equal to 8 degrees and less than or equal to 15 degrees. The upward rotation angle of the lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X can be, but is not limited to, 8 degrees, 9 degrees, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, and 15 degrees. For example, in this embodiment, the upward rotation angle of the lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X is 10 degrees. The downward rotation angle of the lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X is greater than or equal to -15 degrees and less than or equal to -8 degrees. The downward rotation angle of the lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X can be, but is not limited to, -15 degrees, -14 degrees, -13 degrees, -12 degrees, -11 degrees, -10 degrees, -9 degrees, and -8 degrees. In this embodiment, the lock cylinder shaft 133 rotates downwards by an angle of -10 degrees relative to the lock cylinder shaft cover 134 along the first direction X. The first direction X can be, but is not limited to, a direction perpendicular to the surface of the door body 20.

[0068] The range of upward rotation angle of the aforementioned lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X can be defined by the first spherical limiting surface 13523 on at least one side of the lower portion of the aforementioned first spherical surface 13521 and the first shaft cover limiting surface 13411 inside the lock cylinder shaft cover 134. The range of downward rotation angle of the aforementioned lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X can be defined by the first spherical limiting surface 13523 on at least one side of the upper portion of the aforementioned first spherical surface 13521 and the first shaft cover limiting surface 13411 inside the lock cylinder shaft cover 134.

[0069] In some embodiments, the lock cylinder shaft 133 rotates to the right relative to the lock cylinder shaft cover 134 in the first direction X by an angle greater than or equal to 8 degrees and less than or equal to 15 degrees. The angle of right rotation of the lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X can be, but is not limited to, 8 degrees, 9 degrees, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, and 15 degrees. In this embodiment, the lock cylinder shaft 133 rotates to the right relative to the lock cylinder shaft cover 134 in the first direction X by an angle of 10 degrees. The angle of left rotation of the lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X is greater than or equal to -15 degrees and less than or equal to -8 degrees. The angle of left rotation of the lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 in the first direction X can be, but is not limited to, -15 degrees, -14 degrees, -13 degrees, -12 degrees, -11 degrees, -10 degrees, -9 degrees, and -8 degrees. In this embodiment, the lock cylinder shaft 133 can rotate 10 degrees to the left relative to the lock cylinder shaft cover 134 along the first direction X.

[0070] The range of rightward rotation angle of the aforementioned lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 along the first direction X can be defined by the right second spherical limiting surface 13525 of the aforementioned first spherical surface 13521 and the second shaft cover limiting surface 13412 inside the lock cylinder shaft cover 134. The range of leftward rotation angle of the aforementioned lock cylinder shaft 133 relative to the lock cylinder shaft cover 134 along the first direction X can be defined by the left second spherical limiting surface 13525 of the aforementioned first spherical surface 13521 and the second shaft cover limiting surface 13412 inside the lock cylinder shaft cover 134.

[0071] Please see Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 as well as Figure 16 , Figure 11 This is a schematic diagram of the first structure of the lock cylinder in one embodiment of the smart lock of this application; Figure 12 This is a schematic diagram of the first cross-section of the lock cylinder in one embodiment of the smart lock of this application; Figure 13 This is a schematic diagram of the second cross-section of the lock cylinder in one embodiment of the smart lock of this application; Figure 14 This is a schematic diagram of the second structure of the lock cylinder in one embodiment of the smart lock of this application; Figure 15 This is a schematic diagram of the third cross-section of the lock cylinder in one embodiment of the smart lock of this application;

[0072] Figure 16 This is a schematic diagram of the fourth cross-section of the lock cylinder in one embodiment of the smart lock of this application. Combined with... Figure 1 , Figure 2 , Figure 5 as well as Figure 6 In some embodiments, the lock cylinder 12 further includes a swing shaft 123. The swing shaft 123 is disposed within the lock cylinder body 121. The swing shaft 123 is detachably or fixedly connected to the lock cylinder body 121. The swing shaft 123 is perpendicular to the extending direction of the lock cylinder body 121. The lock cylinder body 121 extends along a first direction X, and the swing shaft 123 extends along a second direction Y. The second direction Y is perpendicular to the first direction X and parallel to the surface of the door body 20. A lock cylinder hole 1221 is provided at one end of the lock cylinder rod 122 near the lock cylinder body 121. The lock cylinder rod 122 is sleeved onto the swing shaft 123 through the lock cylinder hole 1221. The lock cylinder hole 1221 and the swing shaft 123 are clearance-fitted, allowing the lock cylinder rod 122 to rotate at the end of the lock cylinder body 121 near the second end face 11b.

[0073] Through the cooperation of the lock cylinder body 121, the swing shaft 123, and the lock cylinder rod 122, not only can the lock cylinder body 121 be rotated at the end near the second end face 11b, but the structure is also simple and easy to implement. When the lock cylinder body 121 is connected to the lock body 11, the lock cylinder body 121 at least partially protrudes from the end near the second end face 11b.

[0074] In some embodiments, a lock cylinder body 121 has a lock cylinder body groove 1211 at one end facing the lock door panel 13. The lock cylinder body groove 1211 can accommodate a swing shaft 123 and at least a portion of the lock cylinder rod 122. The swing shaft 123 is located within the lock cylinder body groove 1211. Different sidewalls of the lock cylinder body groove 1211 define the rotation angle of the lock cylinder rod 122. The aforementioned lock cylinder body groove 1211 serves a limiting function. By providing the lock cylinder body groove 1211 on the lock cylinder body 121, the rotation of the lock cylinder rod 122 can be limited to the end of the lock cylinder body 121 near the second end.

[0075] In one specific embodiment, the lock cylinder body recess 1211 is square. The lock cylinder body recess 1211 includes opposing first sidewalls (not shown in the figure) and opposing second sidewalls (not shown in the figure). The two first sidewalls are vertically arranged along a first direction X. The two second sidewalls are horizontally arranged along the first direction X. The lock cylinder rod 122 rotates vertically within the lock cylinder body 121 along the first direction X, and the opposing first sidewalls limit the range of vertical rotation angle of the lock cylinder rod 122 along the first direction X. The lock cylinder rod 122 rotates horizontally within the lock cylinder body 121 along the first direction X, and the opposing second sidewalls limit the range of horizontal rotation angle of the lock cylinder rod 122 along the second direction Y.

[0076] In another specific embodiment, the lock cylinder shaft 133 is provided with a lock cylinder groove 1331. The lock cylinder rod 122 is inserted into the lock cylinder groove 1331. A guide portion 1332 is provided at the end of the lock cylinder shaft 133 away from the lock door panel 13. The guide portion 1332 is located at the end of the lock cylinder groove 1331 away from the lock door panel 13. The guide portion 1332 serves a guiding function. By providing a guide portion 1332 on the lock cylinder shaft 133, it is easier for the lock cylinder rod 122 to be inserted into the lock cylinder shaft 133, thereby improving the installation efficiency of the smart lock 10, etc.

[0077] In some embodiments, the lock cylinder rod 122 rotates upward relative to the lock cylinder body 121 along the first direction X by an angle greater than or equal to 8 degrees and less than or equal to 15 degrees. The angle of rotation of the lock cylinder rod 122 relative to the lock cylinder body 121 along the first direction X can be, but is not limited to, 8 degrees, 9 degrees, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, and 15 degrees. For example, in this embodiment, the lock cylinder rod 122 rotates upward relative to the lock cylinder body 121 along the first direction X by an angle of 10 degrees.

[0078] The lock cylinder rod 122 rotates downward relative to the lock cylinder body 121 along the first direction X by an angle greater than or equal to -15 degrees and less than or equal to -8 degrees. The downward rotation angle of the lock cylinder rod 122 relative to the lock cylinder body 121 along the first direction X can be, but is not limited to, -15 degrees, -14 degrees, -13 degrees, -12 degrees, -11 degrees, -10 degrees, -9 degrees, and -8 degrees. In this embodiment, the downward rotation angle of the lock cylinder rod 122 relative to the lock cylinder body 121 along the first direction X is -10 degrees.

[0079] The upward and downward rotation angles of the lock cylinder rod 122 relative to the lock cylinder body 121 along the first direction X can be achieved by the cooperation of the lock cylinder hole 1221, the swing shaft 123 and the groove 1211 of the lock cylinder body on the lock cylinder rod 122.

[0080] In some embodiments, the lock cylinder rod 122 rotates to the right relative to the lock cylinder body 121 in the first direction X by an angle greater than or equal to 8 degrees and less than or equal to 15 degrees. The angle of rotation to the right relative to the lock cylinder body 121 in the first direction X can be, but is not limited to, 8 degrees, 9 degrees, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, and 15 degrees. For example, in this embodiment, the lock cylinder rod 122 rotates to the right relative to the lock cylinder body 121 in the first direction X by an angle of 10 degrees.

[0081] The lock cylinder rod 122 rotates to the left relative to the lock cylinder body 121 in the first direction X by an angle greater than or equal to -15 degrees and less than or equal to -8 degrees. Specifically, the angle of rotation to the left relative to the lock cylinder body 121 in the first direction X can be, but is not limited to, -15 degrees, -14 degrees, -13 degrees, -12 degrees, -11 degrees, -10 degrees, -9 degrees, and -8 degrees. In this embodiment, the angle of rotation to the left relative to the lock cylinder body 121 in the first direction X can be 10 degrees.

[0082] The rotation angles of the lock cylinder rod 122 relative to the lock cylinder body 121 in the first direction X to the left and to the right can be achieved by the cooperation of the lock cylinder hole 1221, the swing shaft 123 and the groove 1211 of the lock cylinder body on the lock cylinder rod 122.

[0083] Please see Figure 17 , Figure 17 This is a structural diagram of the smart lock of this application installed on a door. (Combined with...) Figures 1 to 10In some embodiments, the positional offset distance of the lock panel 13 relative to the lock body 11 is greater than or equal to 6 mm and less than or equal to 15 mm. This positional offset distance can be, but is not limited to, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, and 15 mm. By limiting the above-mentioned positional offset distance, the positional offset distance between the lock panel 13 and the lock cylinder 12 can be limited. For example, in this embodiment, the positional offset distance of the lock panel 13 relative to the lock body 11 is 10 mm.

[0084] In one specific embodiment, the positional offset distance of the lock panel 13 relative to the lock body 11 along the second direction Y and away from the door frame 30 is greater than or equal to 6 mm and less than or equal to 15 mm. By limiting the above-mentioned positional offset distance, the distance between the lock panel 13 and the door frame 30 can be adjusted, thereby solving the technical problem of the door frame 30 injuring or pinching hands during the opening or closing of the door 20. When the smart lock 10 is installed on the door 20, the lock panel 13 can be moved away from the door frame 30, thereby increasing the distance between the lock panel 13 and the door frame 30, thus reducing the risk of the door frame 30 injuring the user's hand or pinching fingers, without changing other structures.

[0085] In some embodiments, the smart lock 10 includes a bearing 14. The bearing 14 is sleeved on the outer periphery of the knob 132 and located at the end of the lock panel body 131 opposite to the knob 132. The bearing 14 is stably sleeved on the outer periphery of the knob 132 during the removal of the lock cylinder cover 134 from the knob 132. The smart lock 10 also includes a drive motor (not shown in the figure). The drive motor can be controlled by electrical signals to lock and unlock, etc.

[0086] Please see Figure 18 , Figure 18 This is a cross-sectional schematic diagram of the smart lock of this application installed on a door. (Combined with...) Figures 1 to 17 In some embodiments, the thickness of the door body 20 is defined as A; the distance between the end of the lock cylinder body 121 away from the lock body 11 and the inner side of the door body 20 is defined as B; the distance between the inner side of the door body 20 and the end of the lock cylinder shaft cover 134 near the knob 132 is defined as L; the offset distance of the lock door panel 13 relative to the lock body 11 is defined as C; and the rotation angle of the lock cylinder shaft 133 is defined as D. To more clearly illustrate the relationships between A, B, L, C, and D, all of A, B, L, C, and D are greater than 0. D = arctan(C / (B+L)). That is, C = (B+C)tanD. In other words, C is related to A, B, L, and D. L can be a fixed value, such as 41.3 mm, depending on the type of door body 20, and is not limited here. In practice, the offset distance of the lock door panel 13 relative to the lock body 11 can also be related to other factors, and is not limited here.

[0087] In a specific application scenario, the user rotates the knob 132. The knob 132 drives the lock cylinder cover 134 and the lock cylinder shaft 133 to rotate. The lock cylinder shaft 133 drives the lock cylinder rod 122 to rotate, enabling the lock cylinder 12 to drive the bolt (not shown in the figure) on the lock body 11 to move, thereby realizing the unlocking of the smart lock 10.

[0088] The terms "first," "second," and "third" in this application are for descriptive purposes only and should not be construed as indicating the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of those features. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indications will change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. A process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0089] The above description is merely an embodiment of this application and does not limit the patent scope of this application.
