Description

Technical Field

[0001] The present application relates to the technical field of lock structures, and in particular to a fake lock, a lock and a door. Background Art

[0002] As the core component of door locks, the security of smart locks is particularly important. Smart locks usually use fingerprint recognition, password input, iris recognition and other authentication methods to generate electrical signals to control the motor to unlock, which is not only convenient for users to use, but also increases the security of door locks.

[0003] In the related art, the fake lock usually controls the action of the clutch assembly by inserting and removing the key, so that the two unlocking components located inside and outside the door are not linked during the unlocking process of the dial wheel.

[0004] However, in a fully automatic smart lock, the door is unlocked by inserting a key from the outside to switch the clutch assembly. A keyhole needs to be opened on the control panel of the smart lock, and a shielding cover is usually provided for the keyhole. In particular, a control panel with a bridge structure is provided with two upper and lower key covers and a larger sliding cover. During the unlocking process, the sliding cover needs to be moved downward or upward first, and then the two key covers are opened in turn before the key can be inserted into the keyhole to unlock the door. Not only is the lock body structure complicated, but the operating steps of opening and closing the lock are also cumbersome. Summary of the invention

[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0062] In the related art, the fake lock usually controls the action of the clutch assembly by inserting and removing the key, so that the two unlocking components located inside and outside the door are not linked during the unlocking process of the dial wheel.

[0063] However, in a fully automatic smart lock, the door is unlocked by inserting a key from the outside to switch the clutch assembly. A keyhole needs to be opened on the control panel of the smart lock, and a shielding cover is usually provided for the keyhole. In particular, a control panel with a bridge structure is provided with two upper and lower key covers and a larger sliding cover. During the unlocking process, the sliding cover needs to be moved downward or upward first, and then the two key covers are opened in turn before the key can be inserted into the keyhole to unlock the door. Not only is the lock body structure complicated, but the operating steps of opening and closing the lock are also cumbersome.

[0064] Therefore, the present application provides a fake lock, a lock and a door to improve the problems of complex structure and complicated operation steps of smart locks.

[0065] Combine the following Figures 1 to 10 , describing an embodiment of the present application.

[0066] According to an embodiment of the present application, on the one hand, a fake lock is provided, such as Figures 1 to 3 As shown, it includes a lock housing 1, a first drive assembly 2, a second drive assembly 3, a clutch assembly 4 and a dial wheel 5.

[0067] Specifically, the lock housing 1 is generally a copper housing or a metal housing. The lock housing 1 is suitable for being fixedly arranged in the lock body by bolts or screws. The lock housing 1 is provided with a housing cavity 11 extending along a first direction. An anti-rotation portion 12 is movably arranged on the inner wall surface of the housing cavity 11. Specifically, the housing cavity 11 is divided into a plurality of sections along the first direction. Each section can be selected and set with different types of cross sections according to the use of the matching components. The first direction is as follows: Figure 1 as shown in .

[0068] The first driving assembly 2 is rotatably disposed in the accommodating cavity 11 .

[0069] like Figure 1 and Figure 4 As shown, the second driving assembly 3 includes a second rotating drum 31, a rotating wheel 32 and a push rod 33. The second rotating drum 31 is a metal cylinder, or a highly wear-resistant plastic cylinder, etc. The second rotating drum 31 is rotatably arranged in the accommodating chamber 11. At this time, the matching cross-sectional shape of the accommodating chamber 11 and the second rotating drum 31 is circular, and the anti-rotation portion 12 can limit the rotation of the second rotating drum 31. The rotating wheel 32 is rotatably arranged in the second rotating drum 31. The second rotating drum 31 is provided with an angle limiting portion 311 to limit the rotation angle of the rotating wheel 32, that is, the angle limiting portion 311 can limit the reciprocating rotation of the rotating wheel 32 within a certain angle range. During the rotation of the rotating wheel 32, the push rod 33 can push the push rod 33 to move in the direction of the first driving assembly 2. During the movement, the push rod 33 can unlock the anti-rotation portion 12 to enable the second rotating drum 31 to rotate.

[0070] like Figure 1 As shown, the clutch assembly 4 is located in the space between the push rod 33 and the first driving assembly 2 in the accommodating chamber 11 .

[0071] The dial wheel 5 is sleeved on the clutch assembly 4.

[0072] Among them, the clutch assembly 4 can switch to different states under the respective forces of the push rod 33 and the first drive assembly 2, so that the dial wheel 5 can be meshed with the first drive assembly 2 or the second rotating drum 31 for transmission, that is, the clutch assembly 4 is switched to the first state to achieve the meshing transmission of the dial wheel 5 and the first drive assembly 2, and the clutch assembly 4 is switched to the second state to achieve the meshing transmission of the dial wheel 5 and the second rotating drum 31.

[0073] It should be noted that the first drive component 2 can have the same structure as the first drive component 2 to switch the state of the clutch component 4; of course, the first drive component 2 can also be a lock core structure, and the state switching of the clutch component 4 is achieved by inserting a key.

[0074] It should be noted that the second drive component 3 can be located on any side of the door and can be selected and set according to needs. Correspondingly, the first drive component 2 is located on any other side of the door, that is, the first drive component 2 and the second drive component 3 are respectively located on both sides of the door.

[0075] In the specific working process, the following is an example in which the first drive component 2 is located on the inside of the door (i.e., indoors) and the second drive component 3 is located on the outside of the door (i.e., outdoors). The specific process is as follows:

[0076] like Figure 1 As shown, the outside door drive motor is rotationally connected to the rotating wheel 32 through the paddle 6. When the door needs to be unlocked from the outside, the rotation stroke of the drive motor is divided into a front rotation stroke and a rear rotation stroke. The front rotation stroke drives the rotating wheel 32 to rotate from the initial position to contact with the angle limit portion 311. During this process, the second rotating cylinder 31 remains in a constant position relative to the lock shell 1 under the restriction of the anti-rotation portion 12. The rotating wheel 32 drives the push rod 33 to move toward the direction close to the clutch assembly 4, so that the clutch assembly 4 switches its state, so that the second rotating cylinder 31 engages with the paddle wheel 5, and the first driving assembly 2 and the paddle wheel 5 are in a separated state. At the same time, the push rod 33 can unlock the anti-rotation portion 12, so that the second rotating cylinder 31 is in a state where it can rotate.

[0077] During the latter rotation stroke, the rotating wheel 32 drives the second rotating drum 31 to rotate synchronously under the restriction of the angle limit part 311, and the second rotating drum 31 drives the dial wheel 5 to rotate to unlock; after the unlocking is completed, the outer door drive motor is reversed for reset, so that the rotating wheel 32, the second rotating drum 31, the anti-rotation part 12 and the dial wheel 5 are all reset, and the push rod 33 and the clutch assembly 4 are reset under the action of the first drive assembly 2, and the clutch assembly 4 is switched to another state to unlock the door from the inside.

[0078] In this embodiment, if Figure 1As shown, by arranging the second rotating cylinder 31, the driving wheel and the push rod 33 in the second driving assembly 3, the anti-rotation portion 12 on the lock body limits the second rotating cylinder 31 to rotate in the accommodating chamber 11, and the rotating wheel 32 is rotatably arranged in the second rotating cylinder 31. The second rotating cylinder 31 is provided with an angle limiting portion 311 to limit the rotation angle of the rotating wheel 32. During the rotation process of the rotating wheel 32, the push rod 33 can be pushed to move in the direction of the clutch assembly 4, so that the clutch assembly 4 switches the state, so that the first driving assembly 2 is separated from the dial wheel 5, and the second rotating cylinder 31 is meshed with the dial wheel 5 for transmission. At the same time, the push rod 33 can unlock the anti-rotation portion 12 during the movement, and at the angle limiting portion 3 11, continuing to rotate the driving wheel can drive the second rotating drum 31 to rotate, and the second rotating drum 31 then drives the dial wheel 5 to open and close the lock, so that the state switching and opening and closing of the clutch component 4 can be achieved only by rotating the driving wheel, so as to realize the non-linkage of the two unlocking components located inside and outside the door, thereby eliminating the need to set a lock core on the smart lock panel provided with the second driving component 3, and switching the state of the clutch component 4 and opening and closing the lock by inserting the key, which not only simplifies the structure of the smart lock and improves the aesthetics of the smart lock panel, but also can directly drive the opening and closing of the lock through the motor, thereby simplifying the operation steps of the opening and closing of the lock.

[0079] In one embodiment, Figure 4 As shown, the angle limiting portion 311 is a limiting groove extending circumferentially along the second rotating drum 31, and a limiting column 321 is provided on the rotating wheel 32, and the limiting column 321 is located in the limiting groove. Specifically, the center angle corresponding to the limiting groove can be selected and adjusted according to the driving mode of the rotating wheel 32 on the push rod 33 and the moving distance of the push rod 33.

[0080] In this embodiment, the angle limiting portion 311 is set as a limiting groove extending along the circumference of the second drum 31, and a limiting column 321 is provided on the rotating wheel 32 to cooperate with the limiting groove. The solution is simple and the parts are easy to process and manufacture.

[0081] In some embodiments not shown, a groove extending along the circumference of the rotating wheel 32 may be provided, and a protrusion or a column block may be provided on the inner wall surface of the second rotating drum 31 to rotate with the groove to form an angle limiting portion 311. Of course, this method is not convenient for assembly.

[0082] In one embodiment, Figure 4 and Figure 5 As shown, a guide groove 312 is provided on the second rotating drum 31, and the guide groove 312 extends along the first direction. A guide portion 331 is provided on the push rod 33, and the guide portion 331 is located in the guide groove 312; specifically, the guide portion 331 can be a protrusion or a block, as long as it can slide back and forth in the guide groove 312 along the first direction to prevent the push rod 33 from rotating along its circumferential direction.

[0083] In this embodiment, a guide groove 312 extending along the first direction is provided on the second rotating drum 31, and a guide portion 331 is provided on the push rod 33 to prevent the push rod 33 from rotating and guide the push rod 33. The solution is simple and easy to manufacture, process and assemble.

[0084] In one embodiment, Figure 4 As shown, a driving protrusion 322 is provided at the end of the rotating wheel 32 close to the push rod 33, and a driven groove 332 is provided on the end of the push rod 33 close to the rotating wheel 32. At least a part of the driving protrusion 322 is located in the driven groove 332. During the rotation of the rotating wheel 32, the contact surface between the driven groove 332 and the driving protrusion 322 is a driving inclined surface. The driving inclined surface cooperates with the driving protrusion 322 to enable the push rod 33 to move toward the direction close to the clutch assembly 4; specifically, the shape of the driving protrusion 322 can be one of rectangular, trapezoidal, semicircular, or a combination of at least two of the shapes; and the shape of the driven groove 332 can be trapezoidal, semicircular, etc., as long as it can move in the first direction under the drive of the rotating driving protrusion 322.

[0085] or, as Fig.10 As shown, the rotating wheel 32 is connected to the push rod 33 through a screw 323. Specifically, a screw is provided on any one of the rotating wheel 32 and the push rod 33, and a threaded hole screwed to the screw is provided on the other. The rotating wheel 32 drives the push rod 33 to move through the screw. The structure is simple and easy to manufacture.

[0086] It should be noted that if Figure 4 As shown, there may be a plurality of driving protrusions 322 , and the plurality of driving protrusions 322 are arranged at intervals along the circumference of the rotating wheel 32 ; correspondingly, a plurality of driven grooves 332 are also provided, and are arranged one-to-one with the driving protrusions 322 .

[0087] In this embodiment, the rotating wheel 32 and the push rod 33 are driven by the structure of the driving protrusion 322 and the driven groove 332 or the screw rod structure, and the structure is simple and easy to manufacture and assemble.

[0088] In one embodiment, Figure 1 As shown, a pin groove 121 is provided on the lock housing 1, and an elastic member 122 and a limit pin 123 are provided in the pin groove 121. The limit pin 123 can partially extend into the guide groove 312 under the elastic force of the elastic member 122. A guide slope is provided at the position of the guide portion 331 close to the clutch assembly 4. The guide slope pushes the limit pin 123 into the pin groove 121 during the movement of the push rod 33 toward the clutch assembly 4, thereby unlocking the second rotating cylinder 31. The pin groove 121, the elastic member 122 and the limit pin 123 are the anti-rotation portion 12.

[0089] Specifically, Figure 1 As shown, a limiting step is provided at one end of the pin slot 121, and correspondingly, a step portion cooperating with the limiting step is provided on the limiting pin 123, and the other end of the pin slot 121 is closed by a rivet; the elastic member 122 is specifically a spring.

[0090] In this embodiment, the anti-rotation portion 12 is formed by providing a pin groove 121 on the lock housing 1 and providing an elastic member 122 and a limiting pin 123 in the pin groove 121 , so that the structure is simple and easy to assemble.

[0091] In some embodiments not shown, a lock tongue is rotatably provided on the lock housing 1, and a spring is provided at one end of the lock tongue to keep the lock tongue at a certain angle to circumferentially limit the second rotating cylinder 31; when the guide portion 331 on the push rod 33 can push the lock tongue to rotate and unlock, the spring on the lock tongue is compressed at the same time, which facilitates the resetting of the lock tongue.

[0092] In one embodiment, Figures 1 to 3 As shown, the first driving assembly 2 includes a first rotating drum 21 and a reset component 22. The first rotating drum 21 is a metal cylinder, or a highly wear-resistant plastic cylinder, etc. The first rotating drum 21 is rotatably arranged in the accommodating chamber 11. At this time, the matching cross-sectional shape of the accommodating chamber 11 and the first rotating drum 21 is circular. One end of the reset component 22 is limitedly arranged in the first rotating drum 21, that is, one end of the reset component 22 is limited by a limiting structure in the first rotating drum 21 (such as a limiting surface is set in the first rotating drum 21, etc.) to remain motionless. The reset component 22 can push the clutch assembly 4 to switch states. Specifically, the reset component 22 can be an automatic telescopic device controlled by an electrical signal, etc. The second rotating drum 31 is connected to the driving motor through the tail bar 7.

[0093] like Figure 1 and Fig. 9 As shown, the clutch assembly 4 includes a first engaging component 41 , a second engaging component 42 and an elastic telescopic component 43 .

[0094] Specifically, Figure 1 As shown, the first meshing component 41 can slide back and forth along the first direction, and a push shaft 411 is provided on one end of the first meshing component 41 along the first direction. Specifically, the cross-section of the push shaft 411 is circular, and the push shaft 411 is transmission-connected to the push rod 33 (the transmission connection method is specifically docking), and the other end of the first meshing component 41 along the first direction is pressure-contacted with the reset component 22 (pressure-contact refers to contact with a certain pressure, and of course, the pressure can be very small).

[0095] The second engagement member 42 is rotatably sleeved on the push shaft 411 and can slide back and forth along the first direction.

[0096] like Figure 1As shown, the elastic telescopic member 43 is in compression configuration. Specifically, the elastic telescopic member 43 is a spring. One end of the elastic telescopic member 43 is pressed against the second engagement member 42 , so that the second engagement member 42 maintains a tendency to approach the first drum 21 .

[0097] The push rod 33 can push the first meshing member 41 to move toward the first rotating drum 21 through the push shaft 411 to separate the meshing transmission between the first rotating drum 21 and the thumbwheel 5.
