[0034] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Such as Figures 1 to 3As shown, an anti-theft knob switch device provided by an embodiment of the present invention can be used for a smart lock, comprising a fixing seat 120 for connecting to a lock body 910, and a manual control component 200 for connecting or separating from an unlocking shaft 920 of the lock body 910. The lock body 910 can be installed on the inner side of a door, and the manual control component 200 is installed on the fixing seat 120. A reset member is provided between the fixing seat 120 and the manual control component 200.

[0036] Specifically, the manual control component 200 can rotate circumferentially and slide axially relative to the fixed seat 120. The reset member is an elastic member used to reset the manual control component 200 axially, or the reset member can also be a magnetic member (for example, one end with the same polarity is arranged close to each other, for example, the principle of like charges repel each other to reset the manual control component 200). In this embodiment, the reset member is an elastic member (for example, a metal spring). The manual control component 200 is separated from the unlocking shaft 920 under the elastic force of the elastic member. When the manual control component 200 is pressed, the manual control component 200 can be connected to the unlocking shaft 920 of the lock body, and the unlocking shaft can be driven to rotate by rotating the manual control component 200 to realize the opening and closing of the lock, which has good safety and reliability.

[0037] Specifically, Figures 1 to 5 As shown, the manual control component 200 includes a manual control knob 110 for pressing and rotating and a clutch component 200, wherein the manual control knob 110 is connected to one end of the clutch component 200, and the other end of the clutch component 200 is placed in the fixing seat 120 and is provided with a connection structure for connecting or separating with the unlocking shaft 920. The user cannot directly rotate the manual control knob 110 to activate the unlocking shaft 920 (such as Figure 7 Instead, the manual control knob 110 and the clutch component 200 need to be moved axially (eg, pressed) before the clutch component 200 can be connected to the unlocking shaft 920 (eg, Figure 8 As shown in the figure), the manual control knob 110 can be rotated away from the initial position to activate the unlocking shaft 920. In the locked state, it can prevent criminals from using tools to reach into the door from outside through the door gap to directly turn the manual control knob 110 to unlock the door, thereby improving safety and reliability. When the manual control knob 110 is in the locked state or unlocked state, the clutch component 200 and the manual control knob 110 are automatically reset under the action of the elastic member, that is, the clutch component 200 is separated from the unlocking shaft 920 (as shown in the figure). Figure 7 ), cannot be unlocked by directly rotating the manual control knob 110.

[0038] Specifically, Figures 1 to 5As shown, the connecting structure can be the sleeve part 210. The sleeve part 210 has an inner hole for sleeving the end of the unlocking rotating shaft 920. The cross-section of the unlocking rotating shaft 920 can be non-circular (such as D-shaped, rectangular, etc.), and the shape of the inner hole of the sleeve part 210 can match the shape of the end of the unlocking rotating shaft 920. The clutch component 200 slides axially towards the unlocking rotating shaft 920, and the inner hole of the sleeve part 210 can be sleeved on the end of the unlocking rotating shaft 920.

[0039] Specifically, as Figures 1 to 5 shown, the fixing base 120 has a through hole 121 for the clutch component 200 to pass through, and the fixing base 120 can be fixed to the lock body 910 by screws. The clutch component 200 includes an anti-disengagement structure and a clutch shaft 220 movably passing through the through hole 121. One end of the clutch shaft 220 is connected to the manual control knob 110, and the other end of the clutch shaft 220 is connected to the anti-disengagement structure. The anti-disengagement structure is placed inside the fixing base 120 and abuts against the fixing base 120 under the elastic force of the elastic member. The outer peripheral wall of the clutch shaft 220 has an annular groove 221 along its circumferential direction and a guiding groove 222 extending along its axial direction. The annular groove 221 communicates with the guiding groove 222, and a protruding portion 122 is provided on the peripheral wall of the through hole 121. The protruding portion 122 extends into the guiding groove 222 or the annular groove 221.

[0040] In the unlocking or locking state, the elastic member keeps the clutch member 200 in the unlocking or locking position. The convex portion 122 extends into the guiding groove 222, so that the clutch member 200 and the manual control knob 110 fixedly connected to the clutch member 200 cannot rotate. When the manual control knob 110 is not pressed, the convex portion 122 extends into the guiding groove 222. After the manual control knob 110 is pressed, when the clutch shaft 220 linearly moves to make the convex portion 222 enter the annular groove 221, the connection structure is connected to the unlocking rotating shaft 920, and the clutch shaft 220 can rotate circumferentially relative to the fixed seat 120. If the user presses the manual control knob 110 to axially slide the clutch member 200, the guiding groove 222 axially slides along the convex portion 122, so that the annular groove 221 slides to the position of the convex portion 122. At this time, the clutch member 200 is docked with the unlocking rotating shaft 920 and can rotate synchronously. The user can rotate the manual control knob 110, so that the convex portion 122 is placed in the annular groove 221, that is, the convex portion 122 enters the annular groove 221 from the guiding groove 222 and relatively moves along the circumferential direction of the annular groove 221. When the convex portion 122 no longer faces the guiding groove 222, the clutch member 200 cannot be axially reset under the action of the elastic member. At this time, the clutch member 200 can maintain a stable docking state with the unlocking rotating shaft 920, and the user can continue to rotate the manual control knob 110 to synchronously rotate the unlocking rotating shaft 920 to lock or unlock the door.

[0041] When the user rotates the manual control knob 110 to the unlocking state or the locking state, that is, the guiding groove 222 of the clutch member 200 is rotated to be aligned with the convex portion 122. Under the action of the elastic member, the convex portion 122 can enter the guiding groove 222, so that the clutch member 200 and the manual control knob 110 axially bounce back to the reset position. At this time, the clutch member 200 has been separated (disconnected) from the unlocking rotating shaft 920, and the manual control knob 110 cannot drive the unlocking rotating shaft 920 to rotate. The convex portion 122 has left the annular groove 221 and is located in the guiding groove 222. Under the limitation of the guiding groove 222 and the convex portion 122, the clutch member 200 and the manual control knob 110 cannot rotate. Multiple guiding grooves 222 can be provided, and the guiding grooves 222 are arranged at intervals along the circumferential direction.

[0042] In this embodiment, four guiding grooves 222 are provided, and the four guiding grooves are evenly arranged on the circumferential wall of the clutch shaft 220, that is, the adjacent guiding grooves 222 are circumferentially spaced by 90 degrees. The cross-section of the inner hole of the sleeve portion 210 is square, and the cross-section of one end of the unlocking rotating shaft 920 docked with the sleeve portion 210 is also square to correspond to different lock opening and closing states. In the unlocked state, the protruding portion 122 is placed in the guiding groove 222. When the manual control knob 110 is pressed to dock the clutch component 200 with the unlocking rotating shaft 920, the manual control knob 110 is rotated 90 degrees and then in the locked state. At this time, the protruding portion 122 is aligned with the guiding groove 222 again, so that when the manual control knob 110 is pressed under the elastic force of the elastic member, the protruding portion 122 can exit the annular groove 221 and enter the guiding groove 222, separating the clutch component 200 from the unlocking rotating shaft 920. When unlocking again is needed, the manual control knob 110 needs to be pressed to dock the clutch component 200 with the unlocking rotating shaft 920, and then the manual control knob 110 needs to be rotated 90 degrees to switch to the unlocked state.

[0043] Specifically, as Figures 1 to 8 shown, the anti-detachment structure is a snap ring 224. A clamping groove 223 is provided on the circumferential wall of the clutch shaft 220. A part of the snap ring 224 is clamped in the clamping groove 223, and the other part of the snap ring 224 protrudes out of the clamping groove 223. And the outer peripheral diameter of the snap ring 224 is larger than the diameter of the through hole 121, so that the snap ring 224 can abut against the fixed seat 120 to prevent the clutch component 200 from detaching from the fixed seat 120.

[0044] Specifically, as Figures 1 to 8 shown, a connecting plate 230 is fixedly provided at one end of the clutch shaft 220 close to the manual control knob 110. The connecting plate 230 is fixedly connected to the inside of the manual control knob 110 through a locking member, and the locking member can be a screw; an installation groove matching the connecting plate 230 can be provided inside the manual control knob 110, and the connecting plate 230 can be placed in the installation groove, with high structural reliability.

[0045] Specifically, as Figures 1 to 8 shown, the elastic member is a spring 300. The two ends of the spring 300 respectively abut against the fixed seat 120 and the connecting plate 230. Specifically, an annular accommodating groove 123 is provided on the fixed seat 120. One end of the spring 300 is inserted into the annular accommodating groove 123, and the other end of the spring 300 abuts against the surface of the connecting plate 230 to prevent the spring 300 from shifting, so as to ensure the stability of the spring 300 pushing the manual control knob 110 to reset. Of course, the spring 300 can also abut against the fixed seat 120 and the manual control knob 110.

[0046] Specifically, as Figures 1 to 8As shown, the end surface of the manual control knob 110 may be connected to a decorative cover plate 130 , and the decorative cover plate 130 may be provided with an initial position indicating groove or an initial position indicating protrusion, and may also be provided with a rotation direction indicating groove or a rotation direction protrusion.

[0047] like Figures 1 to 8 As shown, an embodiment of the present invention further provides a smart lock, including a lock body 910 installed on the inner side of a door and the above-mentioned anti-theft knob switch device, wherein a fixing seat 120 of the anti-theft knob switch device is fixedly connected to the lock body 910. The fixing seat 120 can be installed on the outer side of the lock body 910 by screws, one end of the manual control knob 110 can pass through the fixing seat 120, a spring 300 is arranged between the manual control knob 110 and the fixing seat 120, and a guide groove 222 and an annular groove 221 are arranged on the outer periphery of the clutch shaft 220, the annular groove 221 is arranged along the circumferential direction, the guide groove 222 is arranged along the axial direction, one end of the guide groove 222 is connected to the annular groove 221, and the other end of the guide groove 222 extends to the clutch shaft 220. At the front end of the coupling shaft 220, the fixing seat 120 has a protrusion 122 that can be placed in the guide groove 222. The protrusion 122 can be columnar (e.g., cylindrical). After the manual control knob 110 is pressed to overcome the force of the spring 300, the manual control knob 110 can be inserted into the unlocking shaft 920 after axial movement, thereby driving the unlocking shaft 920 to rotate, and the unlocking shaft 920 drives the swing rod 930 to rotate, and the swing rod 930 rotates to drive the lock tongue component 400 to move. At this time, the protrusion 122 is placed in the annular groove 221, so that the manual control knob 110 can rotate, and the manual switch lock is realized.

[0048] When the manual control knob 110 drives the lock tongue component 400 to move to the unlocking or locking state, the manual control knob 110 is released, and the manual control knob 110 is separated from the unlocking shaft 920 under the elastic force of the spring 300 (such as Figure 7 As shown in FIG. 2 ), the protrusion 122 provided on the fixing seat 120 is placed in the guide groove 222 to guide the manual control knob 110 axially and block the rotation of the manual control knob 110. Only after the manual control knob 110 is plugged into the unlocking shaft 920 (as shown in FIG. 2 ), the manual control knob 110 is rotated. Figure 8 As shown in the figure, after the protrusion 122 is placed in the annular groove 221, the manual control knob 110 can rotate relative to the fixed seat 120, so that the manual control knob 110 is pressed and then the control knob 110 is turned to manually drive the lock tongue component 400 to unlock and lock, which effectively prevents criminals from using tools to reach into the door through the door gap from outside to turn the manual control knob 110 to unlock the door. The safety and reliability of the smart lock are better. The user only needs to press and rotate the manual control knob 110, which can be operated with one hand, and the user experience is good.

[0049] Specifically, the lock body 910 includes a housing and a locking tongue component 400, an unlocking rotating shaft 920, a motor 940, a gear 950, and a swing rod 930 disposed within the housing. The motor 940 is drivingly arranged with the gear 950. The gear 950 is rotatably mounted on the housing. One end of the unlocking rotating shaft 920 passes through the gear 950 and is connected to one end of the swing rod 930. The other end of the unlocking rotating shaft 920 extends outside the housing. After the gear 950 rotates, it can drive the swing rod 930 to rotate, and the other end of the swing rod 930 can drive the locking tongue component 400 to extend or retract into the housing.

[0050] Specifically, as Figures 10 to 13 shown, the unlocking rotating shaft 920 is connected to the swing rod 930. The gear 950 is provided with a boss 951. When the gear 950 rotates, it pushes the swing rod 930 to rotate through the boss 951, thereby driving the locking tongue component 400 to extend or retract into the housing.

[0051] Specifically, the swing rod 930 is provided with a connection hole 931. One end of a torsion spring 932 is connected to the connection hole 931, and the other end of the torsion spring 932 is connected within the housing. The connection hole 931 is strip-shaped (oval), facilitating the installation of the torsion spring 932 and being conducive to improving the assembly efficiency.

[0052] Specifically, the locking tongue component 400 includes a locking hook mechanism and a locking tongue slider 410 connected to each other. The locking tongue slider 410 is provided with a strip-shaped hole 411, and a guide member 412 fixed within the housing passes through the strip-shaped hole 411. The guide member 412 can be a screw (a large-headed screw or a capped screw) threadedly connected to the lock body 910. By driving the locking tongue slider 410 to move through the swing rod 930, the locking tongue slider 410 can slide back and forth along the screw to achieve locking and unlocking.

[0053] Specifically, the lock hook mechanism includes a panel 421, a bottom plate 422, a spring piece 423, and two lock hook members 424. The panel 421 and the bottom plate 422 are fixedly connected to each other to form a lock tongue housing. The lock tongue slider 410 is connected to the panel 421. The two lock hook members 424 are symmetrically rotatably arranged between the panel 421 and the bottom plate 422. The spring piece 423 is arranged between the panel 421 and the bottom plate 422 and is located between the two lock hook members 424. The two spring feet of the spring piece 423 respectively abut against the two lock hook members 424. One spring piece 423 can replace two springs 300, which is convenient for installation. Moreover, the two lock hook members 424 are symmetrically arranged, which can effectively prevent malicious door prying. In application scenarios such as sliding doors and push-pull doors, the purpose of reliable locking is achieved. In specific applications, the lock hook member 424 is rotatably connected in the lock tongue housing, and the spring piece 423 is installed in the lock tongue housing. When in the locked state, the first end of the lock hook member 424 extends into the lock groove, and the second end of the lock hook member 424 is pressed and placed in the lock tongue housing. When in the unlocked state, the second end of the lock hook member 424 extends out of the lock tongue housing under the action of the spring piece 423, and the first end of the lock hook member 424 is placed in the lock tongue housing under the action of the spring piece 423, with good reliability.

[0054] Specifically, as Figures 10 to 13 shown, on the side surface of the panel 421 opposite to the bottom plate 422, there is a cylinder 991 with internal threads. The locking member 992 passes through the bottom plate 422 and is threadedly connected to the cylinder 991. At least two of the cylinders 991 respectively pass through the middle parts of the two lock hook members 424.

[0055] Specifically, one end of the lock hook member 424 has a hook portion 4241 close to the side surface of the lock tongue housing, and the other end of the lock hook member 424 has a protrusion portion 4242 close to the side surface of the lock tongue housing. Under the elastic force of the spring piece 423, the protrusion portion 4242 extends out of the side surface of the lock tongue housing, and the hook portion 4241 retracts into the lock tongue housing.

[0056] In specific applications, the lock tongue slider 410, the panel 421, and the bottom plate 422 can adopt a split design. The lock tongue slider 410, the panel 421, and the bottom plate 422 can be directly stamped, with higher strength, convenient installation and assembly, simple process, and no need for surface treatment.

[0057] Specifically, as Figures 1 to 3 and Figure 14 and Figure 15As shown, the intelligent lock further includes a mounting shell 810 for mounting on a door body, a touch control body 800 for controlling the operation of the lock body 910, and a flexible cable 830 for electrically connecting the lock body 910 and the touch control body 800. The lock body 910 and the touch control body 800 are respectively mounted on both sides of the mounting shell 810. The mounting shell 810 is connected with a cable protection structure for protecting the flexible cable 830. A cut is provided at the side end of the mounting shell 810 close to the door body, and the cable protection structure is mounted at the cut. The cable protection structure forms a guiding channel respectively communicating with the lock body 910 and the touch control body 800. The flexible cable 830 is located in the guiding channel, and both ends of the flexible cable 830 extend into the lock body 910 and the touch control body 800. The cable protection structure can be in a "U" shape and sleeved at the cut of the mounting shell 810, and the cable protection structure can be fixedly connected to the mounting shell 810 by screws, which can well protect the flexible cable 830. The flexible cable 830 is not easily damaged and has good reliability. The cable protection piece 820 can be integrally formed by stamping and bending, and has high structural strength.
