[0068] In order to further explain the technical means and effects adopted by the present application to achieve the intended purpose, the present application is described in detail below in conjunction with the accompanying drawings and implementation methods.
[0069] See also Figure 1 and Figure 2 The embodiment of the present application provides a smart lock structure 100, including a housing 10, a connecting assembly 20 and a pressing assembly 30. The housing 10 is used to be fixed in a door (not shown). The housing 10 has a cavity, and part of the connecting assembly 20 and the pressing assembly 30 are both located in the cavity.
[0070] See also Figure 3 and Figure 4 The connecting assembly 20 includes a handheld part 21, a rotating member 22, a base 23 connected to the rotating member 22, and a movable pin 24 movably connected to the rotating member 22, and the handheld part 21 is linked with the rotating member 22. The rotating member 22 includes a rotating disk 221 and a first connecting member 223 connected to the rotating disk 221, and a second connecting member 211 is provided on the handheld part 21. The first connecting member 223 is penetrated through the housing 10 and is clamped and connected with the second connecting member 211, and when the handheld part 21 is rotated, the rotating disk 221 rotates with the handheld part 21 through the cooperation of the first connecting member 223 and the second connecting member 211. The second connecting member 211 can be a groove, and the first connecting member 223 is inserted into the second connecting member 211. The first connecting member 223 is provided with protrusions in the circumferential direction, and the inner wall of the second connecting member 211 is provided with grooves corresponding to the protrusions. The linkage between the first connecting member 223 and the second connecting member 211 is realized through the cooperation of the protrusions and the grooves.
[0071] See also Figure 3 and Figure 4 In some embodiments, the turntable 221 has a central hole 2211 and a receiving groove 222 connected to the central hole 2211, the base 23 is rotatably connected to the central hole 2211, and part of the base 23 is protruded from the turntable 221. A fixing plate 60 is also provided on the turntable 221, and the end of part of the base 23 protruding from the turntable 221 passes through the fixing plate 60, and the setting of the fixing plate 60 is used to limit the base 23 in the central hole 2211 of the turntable 221 in the axial direction of the turntable 221.
[0072] The movable pin 24 is movably arranged in the receiving groove 222, and a limiting ring 251 is fixedly arranged on the outer periphery of the movable pin 24, and a second elastic member 252 is also sleeved on the movable pin 24. A limiting block 253 is convexly arranged on the inner wall of the receiving groove 222, and the limiting block 253 can be arranged near the center hole 2211. The rotating disk 221 is provided with a fixing ring 254 at the end of the receiving groove 222 away from the center hole 2211, and the fixing ring 254 has a through hole 255 for the movable pin 24 to penetrate. The limiting ring 251 is placed in the receiving groove 222 and is slidably arranged between the limiting block 253 and the fixing ring 254. The fixing ring 254 limits the limiting ring 251 in the receiving groove 222, and the fixing ring 254 can prevent the limiting ring 251 from coming out of the receiving groove 222. The two ends of the second elastic member 252 are abutted between the limiting block 253 and the limiting ring 251. The movable pin 24 can also pass through the stop block 253 and extend into the center hole 2211. Since the second elastic member 252 is supported by the stop ring 251, under the elastic action of the second elastic member 252, the second elastic member 252 can push the movable pin 24 through the stop ring 251, so that one end of the movable pin 24 extends out of the rotating member 22, and the other end does not extend into the center hole 2211. Figure 4 At this time, the smart lock structure 100 and the door body are in a locked state.
[0073] A plurality of slots 231 are defined at one end of the base 23 , and the slots 231 correspond to the receiving slots 222 .
[0074] The smart lock structure 100 provided in the present application is described by taking the use inside a door as an example. In some embodiments, the hand-held portion 21 may be a door handle.
[0075] See also Figure 3 , Figure 4 and Figure 5 The pressing assembly 30 is located at one side of the connecting assembly 20. The pressing assembly 30 includes a pressing member 31. The pressing member 31 is located below the movable pin 24 and is used to switch between the first position and the second position. Figure 5 When the pressing member 31 is in the first position, the pressing member 31 abuts against the movable pin 24, and the movable pin 24 is inserted into the base 23 through the slot 231 in the circumferential direction of the rotating member 22 to lock the rotating member 22 to the base 23, thereby restricting the circumferential rotation of the rotating member 22, that is, limiting the rotation of the hand-held part 21. Even if the hand-held part 21 is pulled, it is difficult to rotate, thereby preventing the door lock from being maliciously opened, thereby improving the security of the smart lock structure 100. Figure 4 When the pressing member 31 is in the second position, the pressing member 31 is away from the movable pin 24, and the movable pin 24 is disengaged from the slot 231 of the base 23, so that the rotating member 22 and the base 23 rotate relative to each other, thereby realizing the rotation of the hand-held portion 21, so that the door lock can be opened by the hand-held portion 21.
[0076] In some embodiments, a lock core structure (not shown) is also connected to the turntable 221 , and the lock core structure is used to open the smart lock from inside the door by rotating the handheld part 21 .
[0077] See also Figure 3 and Figure 4 In some embodiments, the smart lock structure 100 further includes a pressure plate 40, and a top pressure member 31 is movably arranged between the housing 10 and the pressure plate 40. The top pressure member 31 can slide along the first direction X, and the axial direction of the movable pin 24 is consistent with the first direction X. The top pressure assembly 30 further includes a first elastic member 35 and a rolling member 36. A hollow positioning column 34 is further provided on the top pressure member 31. The positioning column 34 is arranged along a second direction Y perpendicular to the first direction X, and the positioning column 34 is installed on the top pressure member 31. The first elastic member 35 is placed in the positioning column 34, and part of the rolling member 36 is placed in the positioning column 34, and the rolling member 36 is held between the first elastic member 35 and the pressure plate 40. The top pressure member 31 is pushed along the first direction X, and the rolling member 36 in the top pressure member 31 rolls on the pressure plate 40, thereby realizing the movement of the top pressure member 31, so that the top pressure member 31 is held against the movable pin 24 or separated from the movable pin 24.
[0078] In some embodiments, an internal thread column 51 is disposed on the housing 10 , and the pressure plate 40 is fixed to the housing 10 via the internal thread column 51 with a gap therebetween, and the pressing member 31 is accommodated in the gap.
[0079] See also Figure 5 and Figure 6 In some embodiments, the pressure plate 40 is provided with a first opening 41 and a second opening 42, and the second opening 42 and the first opening 41 are arranged along the first direction X. When the pressing member 31 is located at the first position, part of the rolling member 36 is placed in the first opening 41, and the pressing member 31 abuts against the movable pin 24. Figure 6 When the pressing member 31 is in the second position, part of the rolling member 36 is placed in the second opening 42, and the pressing member 31 is separated from the movable pin 24. The first opening 41 and the second opening 42 are provided on the pressing plate 40 so that the rolling member 36 can be limited in the corresponding openings, so that the pressing member 31 is firmly in the first position or the second position, and the pressing member 31 is prevented from sliding down naturally under the action of gravity.
[0080] See also Figure 6In some embodiments, the inner wall of the first opening 41 and the inner wall of the second opening 42 are both provided with chamfers 43, and the rolling member 36 is placed in the first opening 41 or the second opening 42 through the chamfers 43. The setting of the chamfers 43 further stabilizes the rolling member 36 in the first opening 41 or the second opening 42, and also facilitates the conversion of the pressing member 31 between the first position and the second position. When the rolling member 36 slides on the pressure plate 40, the portion of the rolling member 36 that squeezes the first elastic member 35 and is accommodated in the positioning column 34 increases, and the first elastic member 35 is compressed. When the rolling member 36 is placed in the first opening 41 or the second opening 42, part of the rolling member 36 is accommodated in the first opening 41 or the second opening 42.
[0081] In some embodiments, the rolling element 36 is a ball or a ball pin. If the rolling element 36 is a ball, the inner diameter of the positioning column 34 is close to the outer diameter of the rolling element 36 to prevent the rolling element 36 from moving along the first direction X in the positioning column 34 and deflecting during the movement of the top pressure member 31. If the rolling element 36 is a ball pin (not shown), one end of the ball pin with a ball is held against the pressure plate 40, and the ball is placed in the first opening 41 or the second opening 42. The first elastic element 35 is sleeved on the pin in the ball pin, and the length of the pin is less than the length of the positioning column 34.
[0082] See also Figure 6 In some embodiments, a lever 33 is provided on the mounting plate 311, a slide groove 11 is provided on the housing 10, and one end of the lever 33 extends out of the slide groove 11. The lever 33 is located on the surface of the mounting plate 311 away from the positioning column 34, and the top pressing member 31 can be driven to move by moving the lever 33, thereby facilitating operation. In some embodiments, the slide groove 11 is arranged along the first direction X, and the two ends of the slide groove 11 correspond to the first position and the second position respectively, so as to facilitate the operator to identify its toggle position.
[0083] See also Figure 5 In some embodiments, the top pressure member 31 includes a mounting plate 311 and a top plate 312 disposed on the mounting plate 311. The top plate 312 is used to resist or disengage the movable pin 24. The positioning column 34 is fixed to the mounting plate 311. The housing 10 is also provided with a plurality of positioning plates 13, and the plurality of positioning plates 13 are disposed on both sides of the mounting plate 311 in the third direction Z to limit the movement of the mounting plate 311 in the first direction X to prevent the mounting plate 311 from offsetting during movement, causing the rolling member 36 to fail to accurately slide into the first opening 41 or the second opening 42. In some embodiments, the mounting plate 311 is also provided with a plurality of side plates 32, and the positioning plates 13 constrain the movement of the top pressure member 31 in the first direction X through the side plates 32.
[0084] See also Figure 5In some embodiments, the top plate 312 includes a first arc plate 3121 , and the bending direction of the first arc plate 3121 is consistent with the rotation direction of the rotating member 22 , so that when the turntable 221 rotates, the movable pin 24 can rotate along the first arc plate 3121 .
[0085] In some embodiments, the top plate 312 also includes a second arc plate 3122 and a third arc plate 3123 with the same bending direction, and the first arc plate 3121 is arranged between the second arc plate 3122 and the third arc plate 3123. The bending directions of the second arc plate 3122 and the first arc plate 3121 are opposite, so that when the movable pin 24 rotates to disengage from the first arc plate 3121, it slides along the opposite direction of rotation through the second arc plate 3122 or the third arc plate 3123 to the first arc plate 3121, so that the turntable 221 is reset.
[0086] In some embodiments, the second arc plate 3122 and the third arc plate 3123 are symmetrically arranged with respect to the first arc plate 3121 .
[0087] In some embodiments, the first elastic member 35 and the second elastic member 252 can both be springs, and the elastic members can also be other components such as tension springs or torsion springs.
[0088] In the present application, in the smart lock structure 100, the top pressure member 31 is pressed against the movable pin 24, and the movable pin 24 is plugged into the rotating member 22 and the base 23, so that the rotating member 22 is locked on the base 23, thereby restricting the circumferential rotation of the rotating member 22, that is, limiting the rotation of the handheld portion 21, and even if the handheld portion 21 is pulled, it is difficult to rotate, thereby preventing the door lock from being maliciously opened, thereby improving the safety of the smart lock structure 100. When the top pressure member 31 moves to the second position, the top pressure member 31 is away from the movable pin 24, the movable pin 24 is separated from the base 23, and the rotating member 22 and the base 23 rotate relative to each other, thereby realizing the rotation of the handheld portion 21, so that the door lock is opened by the handheld portion 21.
[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the embodiments, a person skilled in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
