Description

Technical Field

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

[0002] In smart locks, the front panel of the outer lock shell is usually made of glass or various alloys. During the use of smart locks, the front panel may hit the wall, resulting in the glass breaking or the surface being scratched, which makes the home experience very poor.

[0003] To prevent smart door locks from being damaged by collisions during use, doorstops are usually installed on the floor. However, doorstops installed on the floor can easily cause pedestrians to trip. Alternatively, anti-collision silicone pads are attached to the wall for cushioning, but these pads are prone to aging and falling off over time, requiring replacement and causing inconvenience. Utility Model Content

[0004] Therefore, it is necessary to provide a smart lock that prevents the front panel from hitting the wall.

[0005] This application provides a smart lock for installation on a door, comprising an outer lock shell having a cavity inside, and an opening communicating with the cavity on the front panel of the outer lock shell; a movable member arranged along the thickness direction of the front panel, the movable member being at least partially located within the cavity and corresponding to the opening; and a drive mechanism, the power output end of which is drivenly connected to the movable member to drive the movable member to move back and forth along the thickness direction of the front panel, thereby the movable member having the following first and second states: in the first state, the front end of the movable member is hidden inside the outer lock shell; in the second state, the front end of the movable member extends forward through the opening and is located in front of the front panel.

[0006] In one embodiment, a cushioning pad is provided at the front end of the movable member, and at least a portion of the cushioning pad covers the end face of the front end.

[0007] In one embodiment, when the movable member is in the first state, the cushioning pad is at least partially located in front of the opening.

[0008] In one embodiment, an elastic element is provided within the cavity to ensure that the movable member always has a rearward tendency, and the elastic element acts on the movable member.

[0009] In one embodiment, the movable element is a movable rod, and a flange located behind the front panel is provided on the outer peripheral wall of the movable rod. The elastic element is a spring located between the flange and the rear wall surface of the front panel.

[0010] In one embodiment, the flange extends circumferentially along the movable rod.

[0011] In one embodiment, at least two guide rods are provided between the flange and the rear wall of the front panel, arranged circumferentially along the movable rod. The guide rods extend in the front-rear direction, and each guide rod corresponds to a spring, which is sleeved around the periphery of the corresponding guide rod.

[0012] In one embodiment, the spring is sleeved around the periphery of the movable rod.

[0013] In one embodiment, the drive mechanism includes a cam and a motor for driving the cam to rotate. The motor is located behind the movable member and has an output shaft extending in a left-right direction. The cam is eccentrically disposed on the output shaft of the motor and acts on the rear end of the movable member.

[0014] In one embodiment, the motor is configured to: put the movable element in the second state when the door is in the open state and a set time has elapsed, and put the movable element in the first state when the door is in the closed state.

[0015] Compared with existing technologies, in the smart lock provided in this application, the moving part moves along the thickness direction of the outer lock shell under the action of the drive mechanism. When the front end of the moving part extends through the opening, it abuts against the wall, preventing the front panel of the outer lock shell from directly impacting the wall and causing damage, thus achieving the purpose of anti-collision. When anti-collision is not required, the moving part is hidden in the cavity, which can protect the moving part while preventing users from accidentally touching it and getting injured, thus better meeting the needs of users.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0030] like Figures 1 to 6 As shown, this application discloses a smart lock. This smart lock is used for installation on a door 6. Specifically, the smart lock includes an outer lock shell 1, a movable member 2, and a drive mechanism 3. The outer lock shell 1 has an interior cavity 10, and the front panel 11 of the outer lock shell 1 has an opening 111 communicating with the cavity 10. The movable member 2 is arranged along the thickness direction of the front panel 11, i.e., along the front-to-back direction. At least a portion of the movable member 2 can be located within the cavity 10 and corresponds to the opening 111. The power output end of the drive mechanism 3 is connected to the movable member 2, driving the movable member 2 to move back and forth along the thickness direction of the front panel 11. Thus, the movable member 2 has the following first and second states: In the first state, the front end 21 of the movable member 2 is hidden within the outer lock shell 1; in the second state, the front end 21 of the movable member 2 protrudes forward through the opening 111 and is located in front of the front panel 11.

[0031] Understandably, the aforementioned movable component 2 moves along the thickness direction of the outer lock shell 1 under the action of the drive mechanism 3. When the front end 21 of the movable component 2 extends through the opening 111, the front end 21 of the movable component 2 abuts against the wall surface 5, preventing the front panel 11 of the outer lock shell 1 from directly impacting the wall surface 5 and causing damage, thus achieving the purpose of collision protection. When collision protection is not required, the movable component 2 is hidden inside the outer lock shell 1, i.e., in the cavity 10, which can protect the movable component 2 while preventing the user from accidentally touching the movable component 2 and getting injured, thus better meeting the user's needs.

[0032] In one implementation, such as Figures 2-4 As shown, the front end 21 of the aforementioned movable part 2 is provided with a buffer pad 22, at least a portion of which covers the end face of the front end 21. It can be understood that the presence of the buffer pad 22 prevents damage to the wall surface 5 when the movable part 2 comes into contact with the wall surface 5, and also reduces the sound of the movable part 2 hitting the wall surface 5.

[0033] In one embodiment, when the movable member 2 is in the first state, the buffer pad 22 is completely hidden within the opening 111. In another embodiment, when the movable member 2 is in the first state, the front end 21 of the movable member 2 is hidden within the opening 111, while a portion of the buffer pad 22 is located in front of the opening 111. In this embodiment, as... Figure 2 and Figure 4 As shown, when the movable part 2 is in the first state, the front end 21 of the movable part 2 is hidden in the opening 111, while the buffer pad 22 is located in front of the opening 111.

[0034] In one implementation, such as Figures 2-5 As shown, the cavity 10 is provided with an elastic element 4 that ensures the movable member 2 always has a backward movement tendency. The elastic element 4 acts on the movable member 2. It can be understood that the presence of the elastic element 4 allows the movable member 2 to more reliably return to its initial position (i.e., its original position).

[0035] In one embodiment, the movable member 2 is a movable rod, and a flange 23 located behind the front panel 11 is provided on the outer peripheral wall of the movable rod. The elastic member 4 is a spring located between the flange 23 and the rear wall surface of the front panel 11. In another embodiment, the elastic member 4 is a leaf spring.

[0036] In one embodiment, there are multiple flanges 23, which are spaced apart circumferentially along the movable rod. In this embodiment, the flanges 23 extend circumferentially along the movable rod, that is, the flanges 23 are annular.

[0037] In one implementation, such as Figure 2 and Figure 3As shown, at least two guide rods 12 are provided between the flange 23 and the rear wall surface of the front panel 11, arranged circumferentially along the movable rod. The guide rods 12 extend in the front-rear direction, and each guide rod 12 corresponds to a spring, which is sleeved around the corresponding guide rod 12. Specifically, there are two or more guide rods 12. In another embodiment, as... Figure 4 and Figure 5 As shown, the spring is sleeved around the movable rod.

[0038] In one embodiment, the drive mechanism 3 includes a motor 32 and a nut. The nut is threadedly connected to the movable part 2. The motor 32 drives the movable part 2 to move in the front-back direction by rotating the nut.

[0039] In this embodiment, the drive mechanism 3 includes a cam 31 and a motor 32 for rotating the cam 31. The motor 32 is located behind the movable member 2 and has an output shaft extending in the left-right direction. The cam 31 is eccentrically mounted on the output shaft of the motor 32 and acts on the rear end 24 of the movable member 2. In other words, the cam 31 is an eccentric wheel. Thus, during the rotation of the cam 31 driven by the motor 32, the cam 31 pushes the movable member 2 forward, causing the front end 21 of the movable member 2 to extend out of the opening 111, preventing the outer lock shell 1 from directly impacting the wall surface 5 and being damaged. Furthermore, when the cam 31 rotates to a state where it no longer pushes the outer lock shell 1, the movable member 2 moves backward and returns to its initial position under the action of the elastic member 4.

[0040] In one embodiment, the cam 31 includes a main wheel portion 311 and an outwardly protruding portion 312 provided on the outer peripheral wall of the main wheel portion 311. The main wheel portion 311 has a through hole 3111 at its center through which the output shaft of the motor 32 passes. In the first state, the first portion 313 of the outer peripheral wall of the main wheel portion 311, excluding the outwardly protruding portion 312, corresponds to the movable member 2. In the second state, the outwardly protruding portion 312 abuts against the movable member 2.

[0041] The aforementioned motor 32 is configured to: when the door is open and a set time has elapsed, move the movable member 2 to the second state; when the door is closed, move the movable member 2 to the first state. Thus, if the time for opening the smart lock exceeds a set threshold (e.g., 1 second), the movable member 2 automatically extends under the action of the motor 32 and the cam 31, with its front end 21 abutting against the wall 5 to prevent the wall 5 from impacting the outer lock shell 1 and damaging its front panel. When the smart lock is closed, the cam 31 rotates under the drive of the motor 32 to its first part 313, corresponding to the movable member 2. The movable member 2 then returns to its original position (initial position) under the action of the spring, i.e., the movable member 2 is in the first state.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
