DETAILED DESCRIPTION

[0022] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 5 As shown, a push-knob-opening smart door lock 10 of the present solution includes: a housing 11, a password module 12 and an unlocking module 13. The password module 12 and the unlocking module 13 are installed on the housing 11. The password module 12 is used for the user to input a password to control the unlocking module 13 to unlock. When all electronic controls of the smart lock with such a structure fail, the door can be unlocked and opened only by controlling the unlocking module 13 through the mechanical password module 12, which can truly realize keyless door opening and is easy to use.

[0024] As a specific structure, the password module 12 is a mechanical password disk, so that even when the power is off and all electronic controls fail, the door unlocking operation can be performed. Among them, the unlocking module 13 includes: a lock tongue 131, a knob 132, a rotating connection block 133, a driving gear 134, a transmission gear 135 and a driven gear 136. The knob 132 and the rotating connection block 133 are both slidably and rotatably connected to the housing 11, that is, the knob 132 and the rotating connection block 133 can both slide up and down relative to the housing 11 and can rotate relative to the housing 11. A first compression spring 137 is provided between the knob 132 and the housing 11, so that the knob 132 is pushed upward by the first compression spring 137 so that the upper side of the knob 132 contacts the housing 11, and the state in which the upper side of the knob 132 contacts the housing 11 is a locked state. The rotating connection block 133 is located between the knob 132 and the housing 11, and the first compression spring 137 is sleeved on the outer periphery of the rotating connection block 133. A second compression spring 138 is provided between the rotating connection block 133 and the housing 11, so that the rotating connection block 133 is pushed upward by the second compression spring 138 so that the upper side of the rotating connection block 133 contacts the lower side of the knob 132. The state in which the upper side of the rotating connection block 133 contacts the lower side of the knob 132 is also a locked state. The knob 132 is formed with a driving protrusion 1322. The rotating connection block 133 is formed with a first driving groove 1331. The first driving groove 1331 is used for the driving protrusion 1322 to be inserted to drive the rotating connection block 133 to rotate, that is, when the knob 132 is rotated, the knob 132 drives the rotating connection block 133 to rotate through the driving protrusion 1322. The driving gear 134 is fixed to the lower end of the rotating connection block 133 so that it can rotate synchronously with the rotating connection block 133. The transmission gear 135 and the driven gear 136 are both rotatably connected to the housing 11, and the transmission gear 135 is meshed with the driving gear 134 and the driven gear 136 at the same time. In this way, when the rotating connection block 133 rotates, the transmission gear 135 and the driven gear 136 can be driven to rotate through the driving gear 134. The driven gear 136 is provided with a second driving groove 1361. The second driving groove 1361 is used for inserting the lock core rod to drive the lock core rod to rotate so as to achieve unlocking. That is, when the driven gear 136 rotates, it can drive the lock core rod to rotate through the second driving groove 1361, thereby achieving unlocking and opening the door. One end of the lock tongue 131 locks the rotating connection block 133 to prevent the rotating connection block 133 from rotating, thereby preventing unlocking and opening the door. The other end of the lock tongue 131 is connected to the password module 12. When the password module 12 is unlocked, the lock tongue 131 is pulled through the mechanical disk of the password module 12 until one end of the lock tongue 131 is disengaged from the rotating connection block 133, so that the rotating connection block 133 can rotate to unlock and open the door.

[0025] As a specific implementation, the rotating connection block 133 is formed with a locking plane 1332, and one end of the lock tongue 131 is in contact with the locking plane 1332 to prevent the rotating connection block 133 from rotating. When the password module 12 is unlocked, its unlocking disk drives the lock tongue 131 to move backward until one end of the lock tongue 131 is separated from the locking plane 1332. At this time, the rotating connection block 133 loses the resistance force and can rotate.

[0026] Optionally, the rotatable connection block 133 is formed with a locking hole, and one end of the locking tongue 131 is inserted into the locking hole to prevent the rotatable connection block 133 from rotating.

[0027] As a specific implementation, the knob 132 is formed with two driving protrusions 1322. The rotating connection block 133 is formed with two first driving grooves 1331. The knob 132 drives the rotating connection block 133 to rotate through the two driving protrusions 1322 and the two first driving grooves 1331, and the structure is more stable.

[0028] Further, the driving protrusion 1322 is a V-shaped protrusion having an outer inclined surface. The first driving groove 1331 is a V-shaped groove having an inner inclined surface matched with the outer inclined surface.

[0029] Specifically, when the password input of the password module 12 is incorrect, the lock tongue 131 still locks the rotating connection block 133. Even if the knob 132 is rotated and pressed so that the driving protrusion 1322 of the knob 132 is inserted into the first driving groove 1331, thereby forming a whole with the rotating connection block 133, the whole cannot rotate and the door cannot be opened. Ensure the safety of the use of the smart lock. Since the first compression spring 137 drives the upper side of the knob 132 to keep in contact with the housing 11, if the knob 132 is only rotated without pressing the knob 132, the knob 132 and the rotating connection block 133 cannot form a whole, that is, regardless of whether the lock tongue 1311 is retracted or not, the door cannot be opened. In this way, the safety of the use of the smart lock can be guaranteed. At the same time, the use of the first compression spring 137 can ensure that the knob 132 is in a compressed state, and ensure that the knob 132 has a good feel.

[0030] When the locking tongue 131 is not retracted, the knob 132 is rotated and pressed, and the driving protrusion 1322 of the knob 132 is inserted into the first driving groove 1331 of the rotating connecting block 133, so that the knob 132 and the rotating connecting block 133 form a whole. Since the locking tongue 131 is not retracted, a second compression spring 138 is provided between the rotating connecting block 133 and the housing 11, and the rotating connecting block 133 cannot rotate, that is, the whole formed by the knob 132 and the rotating connecting block 133 cannot rotate. At this time, since the driving protrusion 1322 of the knob 132 is a V-shaped structure, the first driving groove 1331 of the rotating connecting block 133 is also a V-shaped structure, the knob 132 and the rotating connecting block 133 slide relative to each other. When sliding, the rotating connecting block 133 moves downward under the drive of the inclined surface, so that the rotating connecting block 133 has a certain buffer space when rotating and sliding up and down. Such a buffer structure ensures that the parts inside the unlocking module 13 will not be destructively damaged by the hard torque, thereby protecting the internal mechanism.

[0031] The patent is designed with a second compression spring 138. When the password module 12 is unlocked successfully and the lock tongue 131 is retracted, the knob 132 is rotated and pressed, and the driving protrusion 1322 of the knob 132 is inserted into the first driving groove 1331 of the rotating connection block 133, so that the knob 132 and the rotating connection block 133 are rotated as a whole. When the lock body inside the door body encounters great resistance, since the driving protrusion 1322 of the knob 132 is a V-shaped structure, the first driving groove 1331 of the rotating connection block 133 is also a V-shaped structure, and a second compression spring 138 is arranged between the rotating connection block 133 and the housing 11, the knob 132 and the rotating connection block 133 can slide relative to each other. When sliding, the rotating connection block 133 moves downward to have a certain buffer space. In this case, such a buffer structure can also ensure that the parts of the lock body inside the door body and the parts in the unlocking module 13 will not be destructively damaged, thereby protecting the internal mechanism.

[0032] The above-mentioned push-type knob to open the smart door lock 10 can be applicable to all smart locks on the market, such as fully automatic smart locks, semi-automatic smart locks, etc.

[0033] As an implementation manner, the second driving groove 1361 is a square groove suitable for a square lock core rod.

[0034] Of course, the second driving groove 1361 may also be a groove adapted to lock core rods of other shapes.

[0035] As a specific embodiment, the housing 11 is provided with a slide groove 111. The slide groove 111 can be used to limit the up and down sliding stroke of the knob 132. The knob 132 forms a mounting protrusion 1321. The knob 132 is rotatably connected to the slide groove 111 through the mounting protrusion 1321 and is pushed by the first compression spring 137 to contact the upper groove wall of the slide groove 111. Such a structure is simple and can be rotatably and slidably connected to the housing 11.

[0036] As a preferred embodiment, the rotating connection block 133 is formed with a contact end 1333. The contact end 1333 is used to contact the housing 11 to limit the sliding stroke of the rotating connection block 133. The distance between the contact end 1333 and the housing 11 is less than or equal to the thickness of the transmission gear 135. The distance between the lower side of the mounting protrusion 1321 and the lower groove wall of the slide groove 111 is equal to the sum of the depth value of the V-shaped groove and the distance value between the contact end 1333 and the housing 11. In this way, the feasibility and compactness of the structure can be ensured.

[0037] As a specific implementation, the housing 11 is formed with a first limiting groove 112. The rotating connection block 133 is formed with a second limiting groove 1334. The first limiting groove 112 is used to limit the position of the first compression spring 137, and the second limiting groove 1334 is used to limit the position of the second compression spring 138.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
