[0028] The following is combined with Figure 1-5 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0029] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "end", "front", "back", "middle", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] like Figure 1-Figure 3 As shown, a smart door lock comprises:

[0033] A back cover 2, a display assembly 1 and two elastic members 3, the back cover 2 is provided with two openings 21, and each opening 21 is provided with at least one protrusion 22, specifically, two ends of the opening 21 are respectively provided with a protrusion 22 arranged opposite to each other (that is, each opening 21 is provided with two protrusions 22), the protrusion 22 acts as a rotating shaft of the elastic member 3, and the protrusion 22 is rectangular in design, and its contact area is large, and the elastic member 3 is better limited on the protrusion 22.

[0034] The rear cover 2 and the display assembly 1 are detachable, specifically connected by bolts, to facilitate assembly and disassembly by the user.

[0035] like Figure 3-Figure 4 As shown, the elastic member 3 is flexibly arranged with the protrusion 22, and the elastic member 3 includes a spiral portion 31, which acts as a torsion force and is compressible, so as to be inserted into the protrusion 22; a first elastic arm 32 and a second elastic arm 33 extending along the spiral portion 31 are respectively provided at both ends of the spiral portion 31, and the first elastic arm 32 and the second elastic arm 33 are both perpendicular to the spiral portion 31, and the spiral portion 31 is connected to the protrusion 22 so that the spiral portion 31 can rotate relative to the protrusion 22.

[0036] like Figure 3-Figure 4As shown, a connecting member 4 is connected to the first elastic arm 32, and the connecting member 4 is parallel to the spiral portion 31. The connecting member 4 is used to cooperate with the door panel to better fix the smart door lock in the door panel; the connecting member 4 includes a first connecting portion 41 connected to the first elastic arm 32 and a second connecting portion 42 connected to the first connecting portion 41, the first connecting portion 41 is parallel to the spiral portion 31, and the second connecting portion 42 is parallel to the first elastic arm 32; a third connecting portion 43 is provided at one end of the second connecting portion 42 away from the first connecting portion 41, the third connecting portion 43 extends in the spiral portion 31, and the third connecting portion 43 is passed through the protrusion 22 to better fix the elastic member 3 on the protrusion 22.

[0037] like Figure 5 As shown, in this embodiment, the second elastic arm 33 is located in the opening 21, further limiting the spiral portion 31 on the protrusion 22, providing a certain torque for the spiral portion 31 and helping the spiral portion 31 and the connecting member 4 to reset.

[0038] like Figure 3 and Figure 4 As shown, in this embodiment, the opening 21 is formed by opening the adjacent two end surfaces, that is, the opening 21 is arranged in an I-shape, which can increase the range of movement of the elastic member 3 and the connecting member 4, so that the elastic member 3 and the connecting member 4 can be further adapted to door panels of different thicknesses.

[0039] The elastic member 3 is a torsion spring, and the connecting member 4 is formed integrally with the elastic member 3. The integral forming arrangement can improve the performance of the product, reduce costs, and improve production efficiency.

[0040] The connecting member 4 and the first elastic arm 32 form a rectangle with a stable structure, which can provide a better fixing effect; the second connecting portion 42 is arranged on the side facing the second elastic arm 33, which saves space and makes the force more balanced, thereby extending the service life of the elastic member 3, and the elastic member 3 provides force support for the connecting member 4, thereby increasing the stability of the connecting member 4 when in use.

[0041] By cooperating with the elastic member 3 and the connecting member 4, the elastic member 3 drives the connecting member 4 to move, so that the smart door lock can be fixed on door panels of different thicknesses, thereby improving the versatility of the smart door lock. At the same time, when the door panel and the smart door lock are fixed, the display component 1 will be closer to the inside of the door panel, reducing the range of the display component 1 protruding from the door panel, making the smart door lock more neat and beautiful as a whole.

[0042] The technical effects of this utility model are mainly reflected in the following aspects:

[0043] Can be adapted to door panels of different thicknesses.

[0044] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
