DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] The following is a detailed description of the smart lock provided by the present invention in conjunction with the embodiments. Figure 1 , Figure 2 , Figure 3 as well as Figure 4 , Figure 1 This is a top view of the smart lock of the present application being installed in an offset position; Figure 2 This is a schematic diagram of the lock body and lock core structure in an embodiment of the smart lock of the present application; Figure 3 This is a schematic diagram of the structure of the door lock panel in an embodiment of the smart lock of the present application; Figure 4 yes Figure 3The structural diagram of A is shown. The present application provides a smart lock. The smart lock 10 is used to be installed on the door body 20 so that the door body 20 can be closed and opened relative to the door frame 30. The smart lock 10 includes a lock body 11, a lock core 12 and a door 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 core 12 includes a lock core body 121 and a lock core rod 122. The lock core body 121 is connected to the lock body 11. Among them, the lock core body 121 is detachably connected to the lock body 11. The detachable connection can be but is not limited to plug-in and snap-in, etc. The lock core rod 122 rotates at one end of the lock core body 121 close to the second end face 11b. Among them, the lock core rod 122 rotates at any angle with one end of the lock core body 121 close to the second end face 11b as the center, that is, the lock core rod 122 is offset by its own degree of freedom. The lock core rod 122 can be connected to one end of the lock core body 121 close to the second end face 11b by means of but not limited to a hinge structure, a spherical structure 135, clearance fit, etc., so that the lock core rod 122 can rotate at one end of the lock core body 121 close to the second end face 11b.

[0040] The door lock panel 13 includes a door lock panel body 131, a knob 132 and a lock core shaft 133. The door lock panel 13 can be located indoors. The knob 132 is rotatably connected to a side of the door lock panel body 131. The knob 132 can rotate relative to a side of the door lock panel body 131, such as the knob 132 rotating clockwise or counterclockwise. The lock core shaft 133 rotates on the knob 132, that is, the lock core shaft 133 is offset by its own degree of freedom. The lock core shaft 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, a clearance fit (not shown in the figure), etc., so that the lock core shaft 133 can rotate on the knob 132. When the lock core shaft 133 rotates on the knob 132, the lock core shaft 133 is located on the other side of the door lock panel body 131. The lock core rod 122 is plugged into the lock core shaft 133, so that the lock core rod 122 and the lock core shaft 133 are connected to each other. The lock door panel 13 is offset relative to the lock body 11. The lock core rod 122 and the lock core shaft 133 can be installed by their own degrees of freedom. If the lock body 11 and the lock core 12 are fixed, the lock door panel 13 can be offset by a certain distance in any direction relative to the lock body 11, so that the lock door panel 13 is offset relative to the lock body 11.

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

[0042] See also Figure 5 , Figure 6 as well as Figure 7 , Figure 5 It is a partial schematic diagram of an embodiment of the smart lock of the present application; Figure 6 It is a partial cross-sectional schematic diagram of an embodiment of the smart lock of the present application; Figure 7 yes Figure 6 The structural diagram of B is shown. Figures 1 to 4 In some embodiments, the door lock panel 13 further includes a lock cylinder shaft cover 134. The lock cylinder shaft cover 134 is connected to one end of the knob member 132 facing the lock cylinder shaft 133. The lock cylinder shaft 133 is detachably connected to one end of the knob member 132 facing the lock cylinder shaft 133. The detachable manner may be, but is not limited to, plug-in, snap-on, and bolt connection. The lock cylinder shaft 133 rotates on the lock cylinder shaft cover 134 through the spherical structure 135, so that the lock cylinder shaft 133 can rotate relative to the knob member 132. By arranging the above-mentioned 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 member 132; but also the convenience of rotation of the lock cylinder shaft 133 can be improved, thereby facilitating operation, etc.; at the same time, it is labor-saving, simple in structure, and easy to assemble.

[0043] The spherical structure 135 can be any structure and is not limited here. For example, in a specific embodiment, the spherical structure 135 includes a spherical space 1351 and a spherical portion 1352. The spherical space 1351 is formed between the interior of the lock core shaft cover 134 and the knob member 132 located on the other side of the lock door panel body 131. The lock core shaft cover 134 is provided with at least a portion of the spherical space 1351, and the knob member 132 is provided with at least a portion of the spherical space 1351 on the other side of the lock door panel body 131.

[0044] The spherical portion 1352 is disposed at the end of the lock core shaft 133 away from the lock core rod 122. The spherical portion 1352 can be detachably or fixedly connected to the end of the lock core shaft 133 away from the lock core rod 122. As in the present embodiment, the spherical portion 1352 is integrally formed with the lock core shaft 133. The spherical portion 1352 rotates in the spherical space 1351, that is, the spherical portion 1352 is in at least partial spherical contact with the spherical space 1351. During the rotation of the spherical portion 1352 in the spherical space 1351, the lock core shaft 133 can rotate relative to the lock core shaft cover 134.

[0045] The lock core shaft cover 134 and the knob 132 are combined to form a spherical space 1351, which provides a degree of mobility. The lock core shaft 133 can rotate slightly in the spherical space 1351, which provides a certain amount of mobility for the lock core shaft 133. The lock core shaft 133 can rotate in any direction, which is not limited here. In addition, the spherical space 1351 and the spherical part 1352 cooperate to facilitate the operation of the lock core shaft 133 to rotate on the lock core shaft cover 134; it saves labor, has a simple structure, is easy to implement, etc.; and it saves space, etc.

[0046] See also Figure 8 , Fig. 9 and Fig.10 , Figure 8 It is a partial explosion diagram of an embodiment of the smart lock of the present application; Fig. 9 This is a schematic diagram of the structure of the lock core shaft cover in an embodiment of the smart lock of the present application;

[0047] Fig.10 Schematic diagram of the structure of the lock core shaft and the spherical part in an embodiment of the smart lock of the present application. 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. The first spherical space 13511 and the second spherical space 13512 both include at least a partial spherical surface. The first spherical space 13511 is provided inside the lock cylinder shaft cover 134. The first spherical space 13511 is used to accommodate at least a portion of the spherical portion 1352. The second spherical portion 13522 can be used to accommodate at least a portion of the spherical portion 1352. The knob member 132 is recessed on one end surface facing the lock cylinder shaft cover 134 to form the second spherical space 13512.

[0048] The spherical portion 1352 includes a first spherical portion 13521 and a second spherical portion 13522. The first spherical portion 13521 and the second spherical portion 13522 are connected. The first spherical portion 13521 and the second spherical portion 13522 are detachably or fixedly connected. As in the present embodiment, the first spherical portion 13521 and the second spherical portion 13522 are integrally formed and connected. The first spherical portion 13521 rotates in the first spherical space 13511. The first spherical space 13511 can accommodate the first spherical portion 13521. When the first spherical portion 13521 rotates in the first spherical space 13511, the first spherical portion 13521 at least partially contacts with at least part of the spherical surface of the first spherical space 13511. The second spherical portion 13522 rotates in the second spherical space 13512. The second spherical space 13512 can accommodate the second spherical portion 13522. When the second spherical portion 13522 rotates in the second spherical space 13512 , at least a portion of the second spherical portion 13522 is in spherical contact with at least a portion 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 core shaft 133 rotate on the lock core shaft cover 134, but it can also save space and reduce space occupancy. In addition, it can also improve the stability of the lock core shaft 133 connected to the lock core shaft cover 134.

[0050] Further, the first spherical space 1351 is a first hemispherical space (not shown in the figure), that is, 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), that is, the second hemispherical space is the other half of another spherical space 1351. The radius of a spherical space 1351 is different from the radius of another spherical space 1351. The first spherical portion 13521 is a first hemispherical portion, that is, the first hemispherical portion is half of a spherical portion 1352. The second spherical portion 13522 is a second hemispherical portion, that is, the second hemispherical portion is half of another spherical portion 1352. The radius of a spherical portion 1352 is different from the radius of another spherical portion 1352.

[0051] Furthermore, the center of the first spherical space 1351 and the center of the second spherical space 1351 are concentrically arranged. The radius of the first spherical space 1351 is greater 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. The center of the first spherical portion 13521 and the center of the second spherical portion 13522 are concentrically arranged, and the radius of the first spherical portion 13521 is greater than the radius of the second spherical portion 13522. For example, the radius of the first spherical portion 13521 is twice the radius of the second spherical portion 13522.

[0052] In addition, the spherical portion 1352 further includes a spherical connection portion 13526. The spherical connection portion 13526 is disposed between the first spherical portion 13521 and the second spherical portion 13522. As in the present embodiment, the spherical connection portion 13526 is integrally formed between the first spherical portion 13521 and the second spherical portion 13522. By providing the spherical connection portion 13526, the spherical portion 1352 can not only improve the overall strength of the spherical portion 1352, but also reduce the risk of disconnection between the first spherical portion 13521 and the second spherical portion 13522.

[0053] In some embodiments, the position offset of the door panel 13 relative to the lock body 11 needs to meet the actual installation conditions, and is not unlimited. Therefore, the degree of freedom of the lock core rod 122 and the degree of freedom of the lock core 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 core rod 122 and the rotation angle of the lock core shaft 133, etc.

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

[0055] The first spherical limiting surface 13523 is in releasable contact with the corresponding first shaft cover limiting surface 13411. The first spherical limiting surface 13523 is in contact with the corresponding first shaft cover limiting surface 13411; or, the first spherical limiting surface 13523 is released from contact with the corresponding first shaft cover limiting surface 13411. When the lock cylinder shaft 133 is not rotated on the lock cylinder shaft cover 134, the first spherical limiting surface 13523 is in a non-contact state with the corresponding first shaft cover limiting surface 13411. The first direction X can be, but is not limited to, perpendicular to the surface direction of the door body 20.

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

[0057] In this embodiment, both upper and lower side surfaces of the first spherical portion 13521 are provided with first spherical limiting surfaces 13523 extending along the first direction X. The lock core shaft cover 134 is provided with a first shaft cover limiting surface 13411 extending along the first direction X. The number of the first shaft cover limiting surfaces 13411 and the number of the first spherical limiting surfaces 13523 are both four.

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

[0059] In some embodiments, a recessed portion 13524 is provided on the left and / or right side of the first spherical portion 13521. The recessed portion 13524 may be, but is not limited to, provided on one of the left side of the first spherical portion 13521 and the right side of the first spherical portion 13521, or both. The bottom wall of the recessed portion 13524 is a second spherical limiting surface 13525. At least one limiting portion 1341 is provided inside the lock core shaft 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 shaft cover limiting surface 13412. The second spherical limiting surface 13525 corresponds to the number of the second shaft cover limiting surface 13412. The second spherical limiting surface 13525 is releasably abutted against the corresponding second shaft cover limiting surface 13412. When the lock core shaft 133 is not rotated on the lock core shaft cover 134, the second spherical limiting surface 13525 is in a non-contact state with the corresponding second shaft cover limiting surface 13412. When the lock core shaft 133 is rotated on the lock core shaft cover 134, the second spherical limiting surface 13525 is in contact with the corresponding second shaft cover limiting surface 13412.

[0060] Through the cooperation of the second spherical limiting surface 13525 of the above-mentioned first spherical portion 13521 and the second shaft cover limiting surface 13412 in the lock core shaft cover 134, the freedom of movement of the lock core shaft 133 left and right along the first direction X and the rotation angle can be achieved relative to the lock core shaft cover 134.

[0061] As in the present embodiment, the second spherical limiting surface 13525 is provided on both the left and right sides of the first spherical portion 13521. There are two second spherical limiting surfaces 13525. Two limiting portions 1341 are provided inside the lock core shaft cover 134 along the first direction X. The two second shaft cover limiting surfaces 13412 in the two limiting portions 1341 are arranged opposite to each other. When the lock core shaft 133 rotates to the left relative to the lock core shaft cover 134 along the first direction X, the second spherical limiting surface 13525 on the left side of the first spherical portion 13521 abuts against the second shaft cover limiting surface 13412 on the left side of the lock core shaft cover 134, thereby limiting the lock core shaft 133 from rotating to the left relative to the lock core shaft cover 134 along the first direction X at the rotation angle of the lock core shaft cover 134. When the lock core shaft 133 rotates right along the first direction X relative to the lock core shaft cover 134, the second spherical limiting surface 13525 on the right side of the first spherical portion 13521 abuts against the second shaft cover limiting surface 13412 on the right side of the lock core shaft cover 134, thereby limiting the lock core shaft 133 from rotating right along the first direction X relative to the lock core shaft cover 134 at the rotation angle of the lock core shaft cover 134.

[0062] In some embodiments, the upper end and / or lower end of the limiting portion 1341 is provided with a first shaft cover limiting surface 13411. For example, the upper end of the limiting portion 1341 may be provided with the first shaft cover limiting surface 13411; or, the lower end of the limiting portion 1341 may be provided with the first shaft cover limiting surface 13411; or, both the upper end and the lower end of the limiting portion 1341 may be provided with the first shaft cover limiting surface 13411. By arranging the first shaft cover limiting surface 13411 on the limiting portion 1341, not only the internal structure of the lock core shaft cover 134 is simplified and easy to form; but also the installation space can be saved. Among them, the relationship between the limiting portion 1341 and the first shaft cover limiting surface 13411, such as the position and quantity, is not limited here.

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

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

[0065] The above-mentioned 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 on the limiting portion 1341, not only the internal structure of the lock core shaft cover 134 is simplified and easy to form, but also the installation space can be saved, etc., and the stability of the lock core shaft cover 134 installed on the knob member 132 can be improved.

[0066] Specifically, when the limiting portion 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 vertically arranged.

[0067] In some embodiments, the lock core shaft 133 rotates upwardly relative to the lock core shaft cover 134 along the first direction X at an angle greater than or equal to 8 degrees and less than or equal to 15 degrees. Wherein, the lock core shaft 133 rotates upward relative to the lock core shaft cover 134 along the first direction X at an angle of but 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 core shaft 133 rotates upward relative to the lock core shaft cover 134 along the first direction X at an angle of 10 degrees. The lock core shaft 133 rotates downward relative to the lock core shaft cover 134 along the first direction X at an angle greater than or equal to -15 degrees and less than or equal to -8 degrees. Wherein, the lock core shaft 133 rotates downward relative to the lock core shaft cover 134 along the first direction X at an angle of but not limited to -15 degrees, -14 degrees, -13 degrees, -12 degrees, -11 degrees, -10 degrees, -9 degrees, -8 degrees, etc. In this embodiment, the lock core shaft 133 rotates downward at an angle of -10 degrees relative to the lock core shaft cover 134 along the first direction X. The first direction X may be, but is not limited to, perpendicular to the surface direction of the door body 20.

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

[0069] In some embodiments, the rightward rotation angle of the lock core shaft 133 relative to the lock core shaft cover 134 along the first direction X is greater than or equal to 8 degrees, and less than or equal to 15 degrees. Among them, the rightward rotation angle of the lock core shaft 133 relative to the lock core shaft cover 134 along the first direction X can be but 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 rightward rotation angle of the lock core shaft 133 relative to the lock core shaft cover 134 along the first direction X is 10 degrees. The leftward rotation angle of the lock core shaft 133 relative to the lock core shaft cover 134 along the first direction X is greater than or equal to -15 degrees, and less than or equal to -8 degrees. Among them, the leftward rotation angle of the lock core shaft 133 relative to the lock core shaft cover 134 along the first direction X can be but not limited to -15 degrees, -14 degrees, -13 degrees, -12 degrees, -11 degrees, -10 degrees, -9 degrees, -8 degrees, etc. As in this embodiment, the lock core shaft 133 can rotate leftwards by 10 degrees along the first direction X relative to the lock core shaft cover 134 .

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

[0072] Fig.16 This is a fourth cross-sectional schematic diagram of a lock core in an embodiment of a smart lock of the present application. Figure 1 , Figure 2 , Figure 5 as well as Figure 6 In some embodiments, the lock core 12 further includes a swing shaft 123. The swing shaft 123 is disposed in the lock core body 121. The swing shaft 123 can be detachably or fixedly connected to the lock core body 121. At the same time, the swing shaft 123 is arranged perpendicular to the extension direction of the lock core body 121. The lock core body 121 is extended along the first direction X, and the swing shaft 123 is extended along the second direction Y. The second direction Y is perpendicular to the first direction X, and the second direction Y is parallel to the surface of the door body 20. A lock core hole 1221 is provided at one end of the lock core rod 122 close to the lock core body 121. The lock core rod 122 is sleeved on the swing shaft 123 through the lock core hole 1221. The lock core hole 1221 is clearance-matched with the swing shaft 123 so that the lock core rod 122 rotates at one end of the lock core body 121 close to the second end surface 11b.

[0073] Through the above-mentioned lock core body 121, the swing shaft 123 and the mutual cooperation of the swing shaft 123, not only the lock core rod 122 is rotated at the end of the lock core body 121 close to the second end surface 11b, but also the structure is simple and easy to implement. When the above-mentioned lock core body 121 is connected to the lock body 11, the lock core body 121 at least partially protrudes from the end of the lock core body 121 close to the second end surface 11b.

[0074] In some embodiments, a lock core body groove 1211 is provided at one end of the lock core body 121 facing the lock door panel 13. The lock core body groove 1211 can accommodate the swing shaft 123 and at least part of the lock core rod 122, etc. The swing shaft 123 is located in the lock core body groove 1211. Different side walls of the lock core body groove 1211 limit the rotation angle of the lock core rod 122. The above-mentioned lock core body groove 1211 can play a limiting role. By providing the lock core body groove 1211 in the above-mentioned lock core body 121, the lock core rod 122 can be limited to rotate at one end of the lock core body 121 close to the second end.

[0075] In a specific embodiment, the lock core body groove 1211 is square. The lock core body groove 1211 includes a first side wall (not shown in the figure) and a second side wall (not shown in the figure) that are arranged opposite to each other. The two first side walls are arranged up and down along the first direction X. The two second side walls are arranged left and right along the first direction X. The lock core rod 122 rotates up and down on the lock core body 121 along the first direction X, and the first side wall that is arranged opposite to each other can limit the rotation angle range of the lock core rod 122 along the first direction X. The lock core rod 122 rotates left and right on the lock core body 121 along the first direction X, and the second side wall that is arranged opposite to each other can limit the rotation angle range of the lock core rod 122 along the second direction Y.

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

[0077] In some embodiments, the lock core rod 122 rotates upward relative to the lock core body 121 along the first direction X at an angle greater than or equal to 8 degrees and less than or equal to 15 degrees. The lock core rod 122 rotates upward relative to the lock core body 121 along the first direction X at an angle of, but 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 core rod 122 rotates upward relative to the lock core body 121 along the first direction X at an angle of 10 degrees.

[0078] The downward rotation angle of the lock core rod 122 relative to the lock core body 121 along 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 core rod 122 relative to the lock core body 121 along the first direction X can be, but not limited to, -15 degrees, -14 degrees, -13 degrees, -12 degrees, -11 degrees, -10 degrees, -9 degrees, -8 degrees, etc. In this embodiment, the downward rotation angle of the lock core rod 122 relative to the lock core body 121 along the first direction X is -10 degrees.

[0079] The upward and downward rotation angle of the lock core rod 122 relative to the lock core body 121 along the first direction X can be achieved by the lock core hole 1221 on the lock core rod 122, the swing shaft 123 and the lock core body groove 1211 cooperating with each other.

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

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

[0082] The rotation angle of the lock core rod 122 to the left and right relative to the lock core body 121 along the first direction X can be achieved by the lock core hole 1221 on the lock core rod 122, the swing shaft 123 and the lock core body groove 1211 cooperating with each other.

[0083] See also Fig.17 , Fig.17 This is a schematic diagram of the structure of the smart lock installed on the door body. Figures 1 to 10In some embodiments, the position offset distance of the door 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. The position offset distance of the door lock panel 13 relative to the lock body 11 may 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 position offset distance, the position offset distance between the door lock panel 13 and the lock core 12 can be limited. For example, in this embodiment, the position offset distance of the door lock panel 13 relative to the lock body 11 is 10 mm.

[0084] In a specific embodiment, the position offset distance of the door 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 position offset distance, the distance between the door lock panel 13 and the door frame 30 can be adjusted, thereby solving the technical problem of the door frame 30 hitting and pinching the hand during the opening or closing of the door body 20. When the smart lock 10 is installed on the door body 20, the door lock panel 13 can move to the side away from the door frame 30, thereby increasing the distance between the door lock panel 13 and the door frame 30, thereby reducing the risk of the door frame 30 hitting the user's hand and pinching the fingers, etc., 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 member 132 and is located at the end of the lock door panel body 131 away from the knob member 132. When the lock core shaft cover 134 is detachable from the knob member 132, the bearing 14 can be stably sleeved on the outer periphery of the knob member 132. The smart lock 10 also includes a drive motor (not shown in the figure). The drive motor can use electrical signals to control locking and unlocking, etc.

[0086] See also Fig.18 , Fig.18 This is a cross-sectional schematic diagram of the smart lock of the present application installed on the door body. 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 core body 121 away from the lock body 11 and the inner side of the door body 20 is B; the distance between the inner side of the door body 20 and the end of the lock core shaft cover 134 close to the knob 132 is L; the position offset distance of the lock door panel 13 relative to the lock body 11 is C; the rotation angle of the lock core shaft 133 is D. In order to facilitate a clearer explanation of the relationship between the above A, B, L, C, and D, A, B, L, C, and D are all greater than 0. D = arctan (C / (B+L)). That is, C = (B+C)tanD. That is, C is related to the above A, B, L, D, etc. The above L can be a fixed value, such as 41.3 mm, depending on the type of door body 20, which is not limited here. In actual practice, the position offset distance of the above lock door panel 13 relative to the lock body 11 can also be related to other factors, which are not limited here.

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