[0038] See also Figures 1 to 7 The hidden knob smart lock 100 of the utility model embodiment includes:

[0039] A mounting plate 10, the mounting plate 10 is arranged on the inner side of the door body;

[0040] A handle assembly 20 disposed on the mounting plate 10;

[0041] A knob assembly 30 rotatably disposed on the handle assembly 20, the knob assembly 30 includes a knob body 31 and a rotating member 32, the knob body 31 includes a connecting end 311 and a driving end 312 connected to and opposite to the connecting end 311, the connecting end 311 is opposite to the mounting plate 10 and is drivingly connected to the lock cylinder in the door body, the driving end 312 is exposed from a side of the handle assembly 20 away from the mounting plate 10, the rotating member 32 is fixed to the driving end 312, and rotating the rotating member 32 can drive the knob assembly 30 to rotate on the handle assembly 20 body; and

[0042] The cover assembly 40 is detachably mounted on the handle assembly 20 , and covers and shields a side of the handle assembly 20 that is away from the mounting plate 10 and the knob assembly 30 .

[0043] In the smart lock 100 with a hidden knob in the embodiment of the utility model, the connecting end 311 of the knob body 31 is transmission-connected to the lock core in the door body to ensure that the lock can be unlocked by the knob body 31, and the driving end 312 of the knob body 31 is covered and shielded by the cover assembly 40 detachably provided on the handle assembly 20, that is, the knob body 31 is hidden by the cover assembly 40, and the main structure of the smart lock 100 exposed on the indoor side is the cover assembly 40, the appearance consistency is better, and there are no protruding parts, thereby improving the security of the smart lock 100.

[0044] For ease of description, the smart lock 100 will be referred to as the smart lock 100 with a hidden knob.

[0045] The smart lock 100 in this embodiment is roughly in the shape of a rectangular parallelepiped. If the smart lock 100 is divided into an upper section and a lower section, the relative upper section and the relative lower section of the smart lock 100 can be understood as the upper half and the lower half of the smart lock 100. The knob assembly 30 is arranged in the relative lower section of the smart lock 100. The relative upper section and the relative upper section of other structures mentioned below can be understood as above.

[0046] In addition, the smart lock 100 of this embodiment is arranged on the inside of the door, that is, the smart lock 100 on the indoor side, and the smart lock 100 may also include a part located on the outside of the door, that is, the smart lock 100 on the outdoor side, and the smart lock 100 on the indoor side is arranged correspondingly to the smart lock 100 on the outdoor side to form a complete smart lock 100. The structure of the smart lock 100 on the outdoor side does not involve the inventive point of this embodiment, so it will not be described in detail here.

[0047] Specifically, the mounting plate 10 is roughly in the shape of a rectangular flat plate, which can be stably installed and fixed on the inner side of the door body in a plane by fasteners such as screws, bolts or rivets, so that the smart lock 100 can be stably fixed on the door body. The handle assembly 20 can be fixed to the mounting plate 10 by fasteners such as screws and bolts, with a good fastening effect and relatively easy assembly and disassembly. The handle assembly 20 has a gripping portion for the user's palm to grasp, and the gripping portion is spaced from the mounting plate 10 to form a space where the palm can be inserted, so that the user's palm can be inserted into the space to grasp the handle assembly 20, thereby facilitating the opening of the door body.

[0048] The knob assembly 30 is used to drive the lock core in the door body. For example, clockwise or counterclockwise rotation can drive the lock core to open or close. The knob body 31 is arranged in the handle assembly 20 and is connected to the lock core. The mounting plate 10 is provided with a through hole corresponding to the connection end 311 of the knob body 31, so that the knob body 31 can be connected to the lock core. The driving end 312 of the knob body 31 is exposed from the surface of the handle assembly 20, so that it can be driven by the rotating member 32 to rotate, thereby driving the lock core to rotate and unlock. That is to say, in this embodiment, the knob body 31 is driven to rotate by the rotating member 32 to drive the locking action.

[0049] In one embodiment, the rotating member 32 may be in the form of a sheet, which reduces the space occupied by the knob assembly 30 and facilitates the shielding and covering of the cover assembly 40. In addition, the rotating member 32 may have two ends protruding to both sides, so that the user can grasp the rotating member 32 with fingers and apply force to rotate it.

[0050] In this embodiment, the cover assembly 40 can be a flat structure, that is, its surface is flat. Therefore, covering the cover assembly 40 on the surface of the handle assembly 20 can make the surface of the smart lock 100 appear flat, with better appearance consistency, no protruding parts, and higher security.

[0051] A recessed space may be formed on one side of the handle assembly 20 facing the cover assembly 40 , and the knob assembly 30 is located in the recessed space. The cover assembly 40 may be at least partially embedded in the recessed space, thereby covering and shielding the knob assembly 30 .

[0052] The detachable manner between the cover assembly 40 and the handle assembly 20 can be snap-fitting, screwing, riveting or pasting, etc. Preferably, the cover assembly 40 can be fixed to the handle assembly 20 by snap-fitting, which is more stable and easier to disassemble and assemble.

[0053] See also Figures 3 to 7 In one embodiment, the knob assembly 30 further includes a reset element 33 disposed on the driving end 312 , and a starting end of the reset element 33 connects the driving end 312 and the handle assembly 20 .

[0054] Specifically, the reset element 33 can be a spring coil, which is arranged on the driving end 312 and connects the driving end 312 and the handle assembly 20 through its starting end. When the user rotates the rotating part 32 to rotate the knob body 31, the reset element 33 can generate a certain resistance to the rotation of the knob body 31, so that the user can receive rotation feedback through the rotating part 32 to determine that the knob body 31 has been successfully operated. After the knob body 31 drives the lock core to unlock, the reset element 33 can apply a reset force to the knob body 31 to return to the initial position, so that the knob body 31 naturally returns to the initial position and drives the lock core back to its original position, ensuring that the subsequent locking can be successful.

[0055] In this embodiment, the reset element 33 gradually contracts when the driving end 312 rotates clockwise, and gradually expands when the driving end 312 rotates counterclockwise.

[0056] See also Figures 3 to 7 In one embodiment, a first limiting portion 3121 is provided on the driving end 312 , the reset element 33 passes through the first limiting portion 3121 , a boss 211 is provided on the handle assembly 20 , and a starting end of the reset element 33 connects the first limiting portion 3121 and the boss 211 .

[0057] Specifically, the first limiting portion 3121 is disposed at the edge of the driving end 312 , and is formed by extending forward (ie, in the direction of the cover assembly 40 ) from the edge of the driving end 312 , and is generally in the shape of an arc wall, and is used for installing and limiting the resetting element 33 .

[0058] The reset element 33 passes through the first limit portion 3121 and can rotate relative to the first limit portion 3121. The boss 211 is provided at a position adjacent to the driving end 312 on the handle assembly 20, specifically, the boss 211 is adjacent to the first limit portion 3121. The starting end of the reset element 33 passes through the top of the first limit portion 3121 and is laterally connected to the boss 211. Since the starting end of the reset element 33 is locked by the first limit portion 3121 at an angle approximately perpendicular to the boss 211, the reset element 33 will not be pulled and rotated as a whole when rotating with the driving end 312, but will present a gradually contracted state or a gradually expanded state.

[0059] See also Figures 3 to 7 In one embodiment, a second limiting portion 3122 opposite to the first limiting portion 3121 is further provided on the driving end 312, and the shape of the second limiting portion 3122 is adapted to the shape of the edge portion of the driving end 312, and the reset element 33 is located between the first limiting portion 3121 and the second limiting portion 3122.

[0060] Specifically, the size of the second limiting portion 3122 is larger than that of the first limiting portion 3121, for example, it may be at least twice the size of the first limiting portion 3121. The second limiting portion 3122 is also arranged at the edge of the driving end 312, and is formed by extending forward from the edge of the driving end 312. It is roughly in the shape of an arc wall and is adapted to the shape of the reset element 33. When the reset element 33 gradually expands to a certain extent as the driving end 312 rotates counterclockwise, the second limiting portion 3122 blocks the reset element 33 with a larger coverage area, thereby preventing the reset element 33 from continuing to expand, thereby preventing the reset element 33 from expanding too large and being unable to fully retract.

[0061] In one embodiment, the connection end 311, the driving end 312, the first limiting portion 3121 and the second limiting portion 3122 are integrally injection molded or integrally cast, and the knob body 31 formed has good integrity and can simplify the manufacturing process of the knob body 31, thereby improving the production efficiency of the knob body 31.

[0062] See also Figures 3 to 7 In one embodiment, the handle assembly 20 is further provided with another boss 211 opposite to the boss 211, and the two bosses 211 are respectively located on both sides of the driving end 312 and are adjacent to the first limiting portion 3121 and the second limiting portion 3122, and fixing holes 321 are provided at both ends of the rotating member 32, and the two bosses 211 correspond to the two fixing holes 321 respectively.

[0063] That is, the handle assembly 20 is provided with two oppositely disposed bosses 211, the two bosses 211 are adjacent to and spaced from the first limit portion 3121 and the second limit portion 3122 respectively, and the two bosses 211 can provide some support for the rotating member 32, so that the rotation of the rotating member 32 is more stable. Both ends of the rotating member 32 are provided with fixing holes 321, and when the rotating member 32 needs to be fixed, the fixing holes 321 can be connected to the bosses 211 to prevent the rotating member 32 from rotating.

[0064] In one embodiment, a mounting hole (such as a screw hole) may be provided in the boss 211 , and fasteners such as screws and rivets may pass through the fixing hole 321 and the mounting hole to fix the rotating member 32 and the boss 211 .

[0065] In addition, the end of the reset element 33 extends outward, and when the knob body 31 rotates to the extreme positions of the two bosses 211, the end of the reset element 33 is limited by the two bosses 211, which can prevent the reset element 33 from over-contracting or over-expanding.

[0066] See also Figures 3 to 6 In one embodiment, the handle assembly 20 includes:

[0067] A handle body 21, wherein the handle body 21 is spaced apart from the mounting plate 10;

[0068] A connecting portion 22 provided at a relatively lower section of the handle body 21 and connected to the mounting plate 10; and

[0069] The mounting portion 23 is disposed on the top of the connecting portion 22 , and the knob body 31 is rotatably disposed in the mounting portion 23 .

[0070] Specifically, the handle body 21 is generally in the shape of a flat plate, which can be held by the palm of a user. The connecting portion 22 protrudes from the relatively lower section of the handle body 21 toward the mounting plate 10, and is connected to the relatively lower section of the mounting plate 10. The handle body 21 is spaced from the mounting plate 10 by the connecting portion 22. The connecting portion 22 can be a hollow structure, which can reduce the weight of the handle assembly 20 while connecting the handle body 21 and the mounting plate 10, thereby reducing the weight of the smart lock 100.

[0071] Since the connecting portion 22 is located at the relatively lower section of the handle body 21, the mounting portion 23 provided at the top of the connecting portion 22 is also located at the relatively lower section of the handle body 21. The mounting portion 23 is a hollow structure penetrating front and back, so that the knob body 31 can pass through the mounting portion 23 and rotate in the mounting portion 23.

[0072] In one embodiment, the handle body 21 , the connecting portion 22 and the mounting portion 23 are integrally injection molded or integrally cast. The formed handle assembly 20 has good integrity and can simplify the manufacturing process of the handle assembly 20 , thereby improving the production efficiency of the handle assembly 20 .

[0073] Preferably, the handle assembly 20 is made of plastic and is manufactured by integral injection molding, which helps to reduce the weight of the handle assembly 20 and control the manufacturing cost.

[0074] See also Figures 3 to 7 In one embodiment, the knob body 31 further includes a pushing portion 3123 formed by the driving end 312 protruding upward, and the pushing portion 3123 is located between the handle body 21 and the mounting plate 10 , and the pushing portion 3123 can rotate synchronously with the knob body 31 .

[0075] Specifically, the pushing portion 3123 is located on the back side of the handle body 21, in the space formed between the handle body 21 and the mounting plate 10. The knob body 31 can be driven to rotate by pushing the pushing portion 3123. In this way, when the rotating member 32 fails and the knob body 31 cannot be normally mobilized to rotate, the knob body 31 can be driven by pushing the pushing member, thereby transmitting the lock core to make a corresponding action to unlock the lock.

[0076] In one embodiment, the connection end 311 , the driving end 312 and the pushing portion 3123 are integrally injection molded or integrally cast, so that the knob body 31 has better integrity and can simplify the manufacturing process of the knob body 31 , thereby improving the production efficiency of the knob body 31 .

[0077] Preferably, the knob body 31 is made of plastic and is manufactured by integral injection molding, which helps to reduce the weight of the knob body 31 and control the manufacturing cost.

[0078] See also Figures 3 to 7 In one embodiment, the rear side of the handle body 21 protrudes forward to form a recess 212, and there is a gap between the mounting portion 23 and the handle body 21. When the knob body 31 rotates, the pushing portion 3123 can rotate synchronously on the recess 212 and in the gap. A mounting opening 213 is opened on the recess 212, and the shape of the mounting opening 213 is adapted to the shape of the driving end 312. The driving end 312 passes through the mounting opening 213 and can rotate on the mounting opening 213.

[0079] Specifically, the recess 212 can be roughly fan-shaped, and its coverage on the handle body 21 is the range in which the push portion 3123 can rotate, and the gap between the mounting portion 23 and the handle body 21 and the design of the recess 212 allow the push portion 3123 and the driving end 312 to rotate, ensuring the rotation of the knob body 31 in the mounting portion 23. The shape of the mounting opening 213 is adapted to the shape of the driving end 312, and is used to avoid the driving end 312 and the push portion 3123, so as to prevent the handle body 21 from blocking the knob body 31, and facilitate the installation of the knob body 31 on the mounting portion 23.
