[0041] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0043] For related technologies, see Figures 1 to 4 The smart door lock generally includes a front panel 300, a rear panel 400 and a lock body 200. The front panel 300 and the rear panel 400 are arranged opposite to each other, and the lock body 200 is between the front panel 300 and the rear panel 400. The front panel 300 is located outdoors, the rear panel 400 is located indoors, and the lock body 200 is located inside the door body. The front panel 300, the rear panel 400 and the lock body 200 are linked by a linkage shaft.
[0044] Specifically, during the operation of the smart door lock, when the user opens the door outdoors, the components on the front panel 300 drive the linkage shaft, the linkage shaft rotates, and the linkage shaft drives the lock spring to retract into the door body, and then the door body opens.
[0045] In general, see Figure 1 and Figure 2The linkage shaft is formed as a square shaft 301. The lock body 200 is provided with a square shaft hole 210. The square shaft 301 is inserted into the square shaft hole 210. The square shaft 301 cooperates with the parts inside the lock body 200 to realize the linkage of the lock spring. A square shaft block 220 is provided at the square shaft hole 210. The square shaft block 220 is formed in a cylindrical shape. The internal through hole of the square shaft block 220 is formed as the square shaft hole 210. The square shaft block 220 is connected to the lock spring in a transmission manner. The square shaft 301 is inserted into the square shaft hole 210. The cross-sectional shape of the square shaft hole 210 and the cross-sectional shape of the square shaft 301 are both formed in a quadrilateral shape. The square shaft 301 cooperates with the square shaft hole 210. The rotation of the square shaft 301 drives the square shaft block 220 to rotate, and the square shaft block 220 drives the lock tongue to rotate.
[0046] In other cases, see Figure 3 and Figure 4 The linkage shaft is formed as a sheet-like paddle 302, and a paddle hole 111 is provided on the lock body 200. The sheet-like paddle 302 is penetrated through the paddle hole 111. The paddle hole 111 cooperates with the components inside the lock body 200 to realize the linkage of the lock spring.
[0047] However, since the square shaft 301 and the sheet-shaped paddle 302 have different shapes, it is necessary to design two lock bodies 200 of different specifications, which is costly and not conducive to the standardization and generalization of the lock body 200 .
[0048] To solve the above technical problems, please refer to Figures 3 to 6 The present application provides a square shaft conversion component 100, which includes a conversion component body 110. The conversion component body 110 is used to pass through the square shaft hole 210 and adapt to the square shaft hole 210. A paddle hole 111 is provided on the conversion component body 110. The paddle hole 111 is used to adapt to the sheet-like paddle 302. In the extension direction of the square shaft hole 210, the paddle hole 111 passes through the conversion component body 110.
[0049] Among them, the adaptation of the conversion component body 110 and the square shaft hole 210 means that the conversion component body 110 and the square shaft hole 210 are fixed in the circumferential direction, that is, the square shaft shift block 220 on the square shaft hole 210 can rotate with the rotation of the conversion component body 110, and then when the sheet-like shift piece 302 is inserted into the shift piece hole 111, the sheet-like shift piece 302 can drive the conversion component body 110 to rotate, and the conversion component body 110 drives the square shaft shift block 220 on the square shaft hole 210 to rotate, thereby realizing linkage with the locking spring.
[0050] Specifically, the cross-sectional shape of the square shaft hole 210 is adapted to the cross-sectional shape of the conversion member body 110. For example, the cross-sectional shape of the square shaft hole 210 is a quadrilateral shape, and the cross-sectional shape of the conversion member body 110 is also a quadrilateral shape. The cross-sectional shape of the paddle hole 111 is adapted to the cross-sectional shape of the sheet-shaped paddle 302. The cross-sectional shape of the paddle hole 111 is a strip shape, and the cross-sectional shape of the sheet-shaped paddle 302 hole 111 is also a strip shape.
[0051] Therefore, when the linkage shaft on the front panel 300 or the rear panel 400 is a square shaft 301, it is not necessary to assemble the square shaft conversion member 100 with the lock body 200; when the linkage shaft on the front panel 300 or the rear panel 400 is a sheet-shaped paddle 302, it is necessary to convert the square shaft 301 to be assembled with the lock body 200.
[0052] In this way, by providing a conversion member with a plectrum hole 111, when the smart door lock linkage shaft is a square shaft 301, the square shaft conversion member 100 can be removed; when the smart door lock linkage shaft is a sheet-shaped plectrum 302, the square shaft conversion member 100 only needs to be assembled. Therefore, by providing a square shaft conversion member 100, a lock body 200 of one specification can meet the requirements of both a smart door lock with a linkage shaft of a square shaft 301 and a smart door lock with a linkage shaft of a sheet-shaped plectrum 302, thereby improving the versatility of the lock body 200, which is conducive to the standardization and generalization of the lock body 200.
[0053] In some embodiments of this application, please refer to Figure 6 and Figure 7 A base 120 is provided at one end of the conversion component body 110, and the base 120 is arranged around the circumferential outer side of the conversion component body 110, that is, the circumferential dimension of the base 120 is greater than the circumferential dimension of the conversion component body 110, that is, the conversion component body 110 can be inserted into the square shaft hole 210, and the base 120 cannot be inserted into the square shaft hole 210. Therefore, the axial direction of the square shaft conversion component 100 is limited by setting the base 120.
[0054] Specifically, the circumferential dimension of the base 120 is greater than the circumferential dimension of the square shaft hole 210 , and the base 120 is formed in a circular shape and is disposed on the circumferential outer side of the conversion member body 110 .
[0055] In some embodiments of the present application, the conversion member body 110 may include a first body portion 130 and a second body portion 140 connected to the base 120 , the first body portion 130 and the second body portion 140 are spaced apart, and a paddle hole 111 is defined between the first body portion 130 and the second body portion 140 .
[0056] It should be noted that the conversion component body 110 is an elastic component. When the conversion component body 110 is inserted into the square shaft hole 210, the first body part 130 can be deformed toward the second body part 140, and the second body part 140 can be deformed toward the first body part 130. When the conversion component body 110 enters the square shaft hole 210, the first body part 130 and the second body part 140 rebound, so that the conversion component body 110 cooperates with the square shaft hole 210.
[0057] In this way, by arranging the first body portion 130 and the second body portion 140 which are arranged at intervals, the processing accuracy of the conversion component body 110 can be reduced while defining the square shaft hole 210, thereby reducing the processing cost.
[0058] Among them, since the first main body portion 130 and the second main body portion 140 can undergo elastic deformation, even if the circumferential dimension of the conversion component body 110 is slightly larger than the circumferential dimension of the square shaft hole 210, the conversion component body 110 can still cooperate with the square shaft hole 210, thereby reducing the processing accuracy of the conversion component body 110 and reducing the processing cost of the conversion component body 110.
[0059] In some embodiments of the present application, the first main body portion 130 includes a first end 131 facing away from the base 120, and a first protrusion 132 is provided on the side of the first end 131 facing away from the second main body portion 140. The first protrusion 132 is located on the outside of the square shaft hole 210 and abuts against the outer edge of the square shaft hole 210.
[0060] Therefore, the first protrusion 132 and the base 120 are both located outside the square shaft hole 210 , and the axial movement of the conversion member body 110 can be limited by the first protrusion 132 and the base 120 .
[0061] In some embodiments of the present application, the second body portion 140 includes a second end 141 facing away from the base 120, and a second protrusion 142 is provided on the side of the second end 141 facing away from the first body. The second protrusion 142 is located outside the square shaft hole 210 and abuts against the outer edge of the square shaft hole 210.
[0062] Thus, by providing the first protrusion 132 , the second protrusion 142 and the base 120 , the circumferential movement of the conversion element body 110 can be restricted.
[0063] In some embodiments of the present application, a first guiding slope 133 is provided on a side of the first protrusion 132 away from the second body portion 140 , and the first guiding slope 133 is inclined toward the second body portion 140 in a direction from the base 120 to the first end 131 .
[0064] In some other embodiments of the present application, a second guiding slope 143 is provided on a side of the second protrusion 142 facing away from the first body portion 130 , and the second guiding slope 143 is inclined toward the first body portion 130 in a direction from the base 120 to the second end 141 .
[0065] It should be noted that when the conversion member body 110 is inserted into the square shaft hole 210, the first end 131 and the second end 141 first contact the square shaft hole 210. Due to the existence of the first protrusion 132 and the second protrusion 142, the first body part 130 and the second body part 140 will be deformed. The first guide slope 133 converts the axial force of the first body part 130 into the lateral force, thereby causing the first body part 130 to deform. The second guide slope 143 converts the axial force of the second body part 140 into the lateral force, thereby causing the second body part 140 to deform. This makes it easier for the conversion member body 110 to be inserted into the square shaft hole 210.
[0066] In some embodiments of the present application, the first main body portion 130 includes a first extension segment 135 and a first movable segment 134, one end of the first extension segment 135 is connected to the base 120, and the other end is connected to the first movable segment 134, and in the direction from the base 120 to the first movable segment 134, the distance between the first movable segment 134 and the second main body portion 140 gradually increases.
[0067] In some other embodiments of the present application, the second main body portion 140 includes a second extension segment 145 and a second movable segment 144, one end of the second extension segment 145 is connected to the base 120, and the other end is connected to the second movable segment 144, and in the direction from the base 120 to the second movable segment 144, the distance between the second movable segment 144 and the first main body portion 130 gradually increases.
[0068] It should be noted that, when the conversion member body 110 is inserted into the square shaft hole 210, the first movable segment 134 and the second movable segment 144 are deformed to the maximum due to the presence of the first protrusion 132 and the second protrusion 142. By gradually increasing the distance between the second movable segment 144 and the first body portion 130 and the distance between the first movable segment 134 and the second body portion 140 in the direction from the base 120 to the second movable segment 144, it is ensured that the first protrusion 132 and the second protrusion 142 can pass through the square shaft hole 210 during the deformation process.
[0069] In some other implementations of this application, please refer to Figures 8 to 10The front panel 300 or the rear panel 400 is provided with a positioning column 303 at the square shaft hole 210, in order to further improve the versatility of the lock body 200 assembly. The square shaft conversion member 100 body is also provided with a positioning column hole 112, which is adapted to the positioning column 303, and the positioning column 303 passes through the conversion member body 110 in the extending direction of the square shaft hole 210.
[0070] In this way, by providing a square shaft conversion member 100 with a positioning column hole 112, the square shaft hole 210 can be converted into a positioning column hole 112, meeting the positioning requirements of the positioning column 303. Therefore, the lock body 200 assembly provided by the present application can meet the needs of smart door locks with the linkage shaft being the square shaft 301 and the sheet-shaped paddle 302, and can also meet the needs of smart door locks with the square shaft hole 210 being the positioning column 303. This improves the versatility of the lock body 200 assembly.
[0071] In some embodiments of the present application, the positioning post hole 112 may be spaced apart from the paddle hole 111 .
[0072] In some other embodiments of this application, please refer to Figure 8 , the positioning post hole 112 can overlap with part of the paddle hole 111. Specifically, the cross-sectional shape of the positioning hole is formed into a circular shape, and the cross-sectional shape of the paddle hole 111 is formed into a rectangular shape, the center of the circle coincides with the center of the rectangular hole, and the length of the rectangle is greater than the diameter of the circle.
[0073] In this way, the paddle hole 111 can limit the position of the sheet-shaped paddle 302 , and the positioning post hole 112 can limit the position of the positioning post 303 .
