[0029] The following is combined with the attached Figures 1-7, the specific embodiments of the present utility model will be further described in detail to make the technical solutions of the present utility model easier to understand and master.

[0030] In this embodiment, it should be understood that the orientation or positional relationship indicated by terms such as "middle", "upper", "lower", "top", "right side", "end", "front", "back", "middle part", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model.

[0031] In addition, in this specific embodiment, if there is no special description of the connection or fixing method between components, the connection or fixing method can be bolt fixing, pin fixing or pin shaft connection, etc. commonly used in the prior art. Therefore, it will not be described in detail in this embodiment.

[0032] The following will Figures 1-7 make a further detailed description of this application.

[0033] As Figure 1 , Figure 2 and Figure 6 shown, an intelligent door lock includes a display component 1 and a rear cover 2. The rear cover 2 is provided with a plurality of openings 21. In this embodiment, there are four openings, and the openings 21 are arranged in an L shape, increasing the area of the openings 21 and further increasing the movement range of the fixing component 3 mentioned later, so as to further facilitate the fixing component 3 to adapt to different door panel thicknesses.

[0034] As Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, there are multiple fixing components 3, which are assembled with the rear cover 2 and respectively cooperate with the openings 21. The number of the fixing components 3 is adapted to the number of the openings 21, and will not be described in detail here. The fixing component 3 includes a shaft body 31 and an elastic component 32 connected to the shaft body 31. A connecting piece 33 is provided on the elastic component 32, and a claw 34 cooperating with the connecting piece 33 is further provided on the shaft body 31. The connecting piece 33 and the claw 34 are partially located outside the opening 21. The claw 34 is used to cooperate with the door panel to fix the intelligent door lock inside the door panel. At the same time, in cooperation with the connecting piece 33, which is connected outside the claw 34, the claw 34 can be forced to hold inward. That is, when the claw 34 is pulled according to the thickness of different door panels to reach a suitable position, the claw 34 can be driven by the elastic component 32 and the connecting piece 33 to reset, so as to better fix the intelligent door lock inside door panels of different thicknesses, so that the intelligent door lock can adapt to different door panel thicknesses. The elastic component 32 includes a spiral piece 321. A first elastic arm 322 and a second elastic arm 323 are respectively provided at both ends of the spiral piece 321. The connecting piece 33 is connected to the spiral piece 321. In this embodiment, the elastic component 32 is a torsion spring, and the elastic component 32 and the connecting piece 33 are integrally formed. Through the integral forming setting, the performance of the product can be improved, and the cost can be reduced and the production efficiency can be increased.

[0035] In a preferred embodiment, the first elastic arm 322 and the second elastic arm 323 are located inside the rear cover 2 (not shown), further limiting the spiral piece 321 inside the rear cover 2, and also providing a certain amount of torsion for the spiral piece 321 and helping the spiral piece 321 drive the connecting piece 33 and the claw 34 to reset.

[0036] As Figure 7 shown, the spiral piece 321 includes a first spiral part 3211 and a second spiral part 3212. The first elastic arm 322 and the second elastic arm 323 are respectively connected to the first spiral part 3211 and the second spiral part 3212. The connecting piece 33 is arranged between the first elastic arm 322 and the second elastic arm 323 and is connected to the first spiral part 3211 and the second spiral part 3212.

[0037] As Figure 4 and Figure 7 shown, the connecting piece 33 includes a first connecting part 331 and a second connecting part 332. A third connecting part 333 is provided between the first connecting part 331 and the second connecting part 332. The first connecting part 331 and the second connecting part 332 are connected to the spiral piece 321. In this embodiment, the connecting piece 33 is arranged in a U shape, with a stable structure, which can provide a better fixing effect. In addition, the connecting piece 33 is arranged between the first elastic arm 322 and the second elastic arm 323, saving space while being more balanced in force, extending the service life of the elastic component 32, and the elastic component 32 provides a force support for the connecting piece 33, increasing the stability of the connecting piece 33 during use.

[0038] As Figures 4 to 6 shown, a plurality of receiving grooves 4 adapted to the shaft body 31 are provided in the rear cover 2. At least one first limiting member 5 is provided on the receiving groove 4. The shaft body 31 is passed through the first limiting member 5. In this embodiment, two first limiting members 5 are provided to prevent the shaft body 31 from disengaging from the receiving groove 4. A second limiting member 6 adapted to the shaft body 31 is provided on the side of the receiving groove 4 to further limit the shaft body 31. A groove 7 adapted to the shaft body 31 is provided on one side of the receiving groove 4 away from the second limiting member 6. The groove 7 can be used for dispensing glue to further fix the shaft body 31.

[0039] The technical effects of the present utility model are mainly reflected in the following aspects:

[0040] It can be adapted to door panels of different thicknesses.

[0041] Of course, the above are only typical examples of the present utility model. In addition, the present utility model can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present utility model.
