[0035] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified.

[0038] In addition, in the present invention, descriptions such as "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] The present invention proposes an intelligent door lock, which can achieve quick unlocking with only one operation step when emergency unlocking is required, greatly improving the efficiency of unlocking, and helping users to quickly unlock the door when they urgently need to open the door, thereby meeting the need to open the door urgently.

[0040] Reference Figures 1 to 3 The smart door lock 100 includes a housing 1, a lock assembly 2, and a pop-up assembly 3. The housing 1 defines an installation cavity 11 and an exposure hole 12, which is connected to the installation cavity 11. The lock assembly 2 includes a cover 4 and a lock core body 5. The lock core body 5 is movably disposed within the installation cavity 11 and is rotatably connected to the lock core body 5. The lock core body 5 is provided with a lock core portion 531. Both the cover 4 and the lock core portion 531 are movably disposed within the exposure hole 12. The cover 4 has a retracted state, in which it covers the lock core portion 531, and an open state, in which it opens the lock core portion 531.

[0041] The pop-up assembly 3 is disposed within the mounting cavity 11 and connected to the housing 1. The lock cylinder body 5 is connected to the pop-up assembly 3. The pop-up assembly 3 has a locked state, in which the lock cylinder body 5 is locked, and an unlocked state, in which the lock cylinder body 5 is unlocked. The cover body 4 is configured to drive the pop-up assembly 3 between the locked and unlocked states when subjected to an external force via the lock cylinder body 5. When the pop-up assembly 3 switches from the locked state to the unlocked state, the cover body 4 switches from the retracted state to the open state. When the cover body 4 switches from the open state to the retracted state, the pop-up assembly 3 switches from the unlocked state to the locked state.

[0042] That is, in the unlocked state, the pop-up assembly 3 pushes the cover body 4 and the lock core body 5 to move in a direction away from the pop-up assembly 3 so that the cover body 4 extends out of the exposure hole 12, and the lock core body 5 is used to drive the cover body 4 to switch from the folded state to the open state after the cover body 4 extends out of the exposure hole 12.

[0043] With this arrangement, when emergency unlocking is required, the user can press the cover 4, causing it to depress under pressure. The cover 4 then forces the lock cylinder body 5 to move toward the pop-up assembly 3 and press against it, switching the pop-up assembly 3 from a locked state to an unlocked state. In the unlocked state, the pop-up assembly 3 pushes the lock cylinder body 5 away from the pop-up assembly 3, allowing the lock cylinder body 5 to move the cover 4, thereby ejecting the cover 4 out of the exposure hole 12. After the cover 4 is ejected out of the exposure hole 12, the lock cylinder body 5 also forces the cover 4 to switch from a closed state to an open state, allowing it to open and reveal the lock cylinder portion 531, making it easier for the user to unlock the door. A single pressing action is all it takes to eject the lock cylinder body 5. As the lock cylinder body 5 is ejected, the cover 4 gradually opens, allowing the ejection of the lock cylinder body 5 and the opening of the cover 4 to occur simultaneously. This significantly improves unlocking efficiency and helps users quickly unlock the door in urgent situations, thus meeting their needs.

[0044] Similarly, when the smart door lock 100 needs to be closed, the user switches the cover body 4 from the open state to the folded state, that is, folds the cover body 4 to cover the lock core part 531. The user only needs to apply a force to the cover body 4. While the cover body 4 is pressed back to expose the hole 12 and gradually pressed down, it also gradually pushes the lock core body 5 toward the pop-up component 3, so that the lock core body 5 can abut against the pop-up component 3. When the pop-up component 3 is pressed by the lock core body 5, it switches from the unlocked state to the locked state, so that the lock core body 5 can be locked to lock the lock core body 5. At this time, the outer surface of the cover body 4 remains flush with the outer surface of the shell 1, and the user can cancel the force applied to the cover body 4. Only one operation step is required to lock the smart door lock 100.

[0045] Among them, the lock core part 531 can be a structure such as a lock core hole or an unlocking hole, and the cover body 4 is used to cover the lock core part 531. On the one hand, it can effectively prevent the lock core part 531 from being exposed to ensure the reliability of the lock core part 531 and improve the anti-theft performance. On the other hand, the cover body 4 can effectively prevent dust from entering the lock core part 531 to ensure the cleanliness of the lock core part 531 and ensure the smoothness of unlocking.

[0046] Reference Figure 1 and Figure 2 The housing 1 includes a front housing 13 and a back housing 14. The front housing 13 is connected to the back housing 14. The front housing 13 and the back housing 14 enclose a mounting cavity 11, and the exposure hole 12 is formed in the front housing 13. The connection between the front housing 13 and the back housing 14 can be a snap connection, a screw connection, or an adhesive connection, as long as it can achieve a secure fixation between the front housing 13 and the back housing 14. No specific limitation is given here.

[0047] The front shell 13 and the back shell 14 facilitate the installation of the lock body assembly 2 and the pop-up assembly 3, thereby saving the time of assembling the smart door lock 100 and improving the efficiency of assembling the smart door lock 100.

[0048] In some embodiments, both ends of the installation cavity 11 are open, which facilitates the installation of the front shell 13 and the back shell 14, so that the front shell 13 and the back shell 14 are respectively installed on the two back sides of the door body to ensure aesthetics.

[0049] Reference Figures 1 to 8 The lock core body 5 includes a mounting body 51 and a self-locking member 52. One end of the cover body 4 is rotatably connected to the mounting body 51, and the self-locking member 52 is arranged inside the mounting body 51. Specifically, one end of the cover body 4 is rotatably connected to one of the two opposite sides of the mounting body 51, and the self-locking member 52 is installed on the other side of the two opposite sides of the mounting body 51. The cover body 4 is provided with a self-locking portion 41, and the mounting body 51 is provided with a through hole 511 for the self-locking portion 41 to pass through. When the cover body 4 is in the folded state, the self-locking portion 41 passes through the through hole 511, and the self-locking member 52 is used to lock or unlock the self-locking portion 41, so as to lock or unlock the cover body 4.

[0050] In this way, the cover body 4 and the self-locking part 52 are respectively installed on the two back sides of the mounting body 51. On the one hand, it is convenient for operation and installation to increase the installation accuracy of the smart door lock 100, reduce installation errors, and improve the overall performance of the smart door lock 100. On the other hand, the structural space of the mounting body 51 can be reasonably utilized, so that the cover body 4, the mounting body 51 and the self-locking part 52 are more compact, effectively improving the compactness between the structures and reasonably utilizing the structural space, thereby improving space utilization.

[0051] The self-locking member 52 can lock the cover 4 when the cover 4 is folded into the exposure hole 12 to lock the cover 4 so that the cover 4 is not easily ejected from the exposure hole 12, thereby ensuring the self-locking performance of the cover 4.

[0052] The lock core body 5 also includes a lock core body 53 and a front lock plate 54. The mounting body 51 has a mounting hole 512 extending therethrough, and the lock core body 53 is mounted within the mounting hole 512. A lock core portion 531 is formed at the end of the lock core body 53 facing the cover 4. The front lock plate 54 has a rotating ear portion 541. One end of the front lock plate 54 is fixedly connected to the end of the lock core body 53 away from the cover 4. The other end of the front lock plate 54 passes through the pop-up assembly 3 and the back shell 14 and extends outside the back shell 14.

[0053] Continue to refer to Figures 1 to 8The lock assembly 2 further includes an elastic torsion member 6, which is rotatably mounted on the mounting body 51. One end of the elastic torsion member 6 abuts the mounting body 51, and the other end of the elastic torsion member 6 abuts the side of the cover 4 facing the mounting body 51. When the cover 4 switches from the folded state to the open state, the elastic torsion member 6 provides a rotational force for the cover 4. In other words, the elastic torsion member 6 is used to provide a rotational force for the cover 4 when the cover 4 is in the open state.

[0054] Two supports 513 are provided on the upper surface of the mounting body 51 in the vertical direction. Two connecting protrusions 42 are provided on the side of the cover 4 facing the mounting body 51, adjacent to the end. The two connecting protrusions 42 are rotatably connected to the two supports 513 in a one-to-one correspondence. The lock body assembly 2 also includes a pin 7, which penetrates the two connecting protrusions 42 and the two supports 513 to stably connect the two connecting protrusions 42 and the two supports 513.

[0055] The elastic torsion member 6 may be a torsion spring, which is sleeved outside the pin 7 and disposed between the two connecting blocks. The torsion spring provides a rotational force for the cover 4 when the self-locking member 52 releases the restriction on the cover 4, so that the cover 4 automatically opens to reveal the lock core 531, making it easier for the user to insert a key into the lock core 531 to unlock the cover.

[0056] It is understandable that the elastic torsion member 6 may also be a torsion plate or a spring plate, and the elastic torsion member 6 may also be other structural members that have the function of providing rotational force, which will not be described in detail here.

[0057] Continue to refer to Figures 1 to 8 The self-locking member 52 includes a self-locking body 521 and an elastic body 522. The self-locking body 521 is movably connected to the mounting body 51 and can move in a direction perpendicular to the movement of the mounting body 51. One end of the elastic body 522 is connected to the self-locking body 521, and the other end is connected to the mounting body 51. The self-locking body 521 is provided with a locking portion 5211. The locking portion 5211 has a locking position for locking the self-locking portion 41 and an unlocking position for unlocking the self-locking portion 41. The elastic body 522 is used to drive the locking portion 5211 to switch from the locked position to the unlocked position in the unlocked state.

[0058] The mounting body 51 is provided with a mounting groove 514 facing away from the cover body 4. The through hole 511 is connected to the mounting groove 514. The self-locking body 521 is assembled in the mounting groove 514 and is located above the through hole 511. The mounting body 51 also has a support portion 515 located in the mounting groove 514. The support portion 515 extends from the bottom of the mounting groove 514 toward the notch of the mounting groove 514. The self-locking body 521 has a limiting groove 5213 on the side facing the support portion 515. One end of the elastic body 522 abuts the support portion 515, while the other end is installed in the limiting groove 5213 and abuts the bottom of the limiting groove 5213.

[0059] The elastic body 522 can be compressed or released by the support portion 515 and the bottom of the limiting groove 5213 to lock or unlock the cover 4. The limiting groove 5213 can also effectively limit the end of the elastic body 522, allowing the elastic body 522 to stably contract or extend, thereby improving the effect of the self-locking body 521 in locking or unlocking the cover 4, thereby improving the performance of the smart door lock 100.

[0060] The wall of the mounting groove 514 is formed with a limit portion 516, which is located above the self-locking body 521. The limit portion 516 limits the movement of the self-locking body 521, thereby limiting the movement range of the self-locking body 521 to a reasonable range, so that the cover body 4 can be quickly locked when it is needed to be locked, or can be quickly unlocked when it is needed to be unlocked, which is efficient and convenient.

[0061] In some embodiments, there are two elastic bodies 522, and correspondingly, there are two supporting portions 515, each located on either side of the through hole 511. Limiting grooves 5213 are provided on both sides of the self-locking body 521, with one end of each elastic body 522 connected to the two supporting portions 515 in a one-to-one correspondence, and the other end of each elastic body 522 pluggingly mating with the two limiting grooves 5213 in a one-to-one correspondence.

[0062] The two elastic bodies 522 can increase the stability and smoothness of the movement of the self-locking body 521, thereby improving the smoothness of the switching of the locking part 5211 between the locked position and the unlocked position, reducing the jamming of the self-locking body 521 as much as possible, and improving the reliability of resetting or locking the self-locking body 521.

[0063] It should be noted that the number of elastic bodies 522 can also be multiple, and is not specifically limited here.

[0064] In some embodiments, the elastic body 522 is an elastic structure, such as a spring, elastic rubber or elastic column. As long as it can provide the self-locking body 521 with a restoring force to switch from the locked position to the unlocked position in the unlocked state, no specific limitation is made here.

[0065] Continue to refer to Figures 1 to 8 The cover body 4 is provided with a self-locking protrusion 411 on the side facing the mounting body 51, and a locking portion 5211 is provided on the side of the self-locking body 521 abutting against the elastic body 522. The self-locking protrusion 411 is provided with a self-locking groove 412, and the locking pin is used to insert or withdraw from the self-locking groove 412 to lock or unlock the self-locking protrusion 411.

[0066] Specifically, a self-locking protrusion 411 is provided on a side of the cover body 4 facing the mounting body 51 to form a self-locking portion 41 , and a locking pin is provided on a side of the self-locking body 521 abutting against the elastic body 522 to form a locking portion 5211 .

[0067] When the cover 4 is in the retracted state, the end of the self-locking projection 411 away from the cover 4 is exposed from the mounting groove 514, and the locking pin is inserted into the self-locking groove 412 to lock the cover 4, thereby preventing the cover 4 from expanding outward. When emergency unlocking is required, the pop-up assembly 3 contacts the restraining member 51, freeing the movement of the locking pin. Under the action of the elastic member 522, the self-locking member 521 drives the locking pin out of the self-locking groove 412, allowing the cover 4 to expand under the action of the elastic torsion member 6, revealing the lock core 531.

[0068] The via hole 511 may be in a flat shape, a square shape, a circular shape, or any other shape.

[0069] The lock core body 5 also includes a limit member 55, which is connected to the side of the mounting body 51 facing away from the cover body 4, that is, the limit member 55 is arranged in the mounting groove 514 and connected to the bottom of the mounting groove 514, and the self-locking body 521 is located on the side of the limit member 55 close to the cover body 4, that is, the self-locking body 521 is located between the bottom of the mounting groove 514 and the limit member 55, and the limit member 55 is used to limit the movement of the self-locking body 521.

[0070] On the one hand, the self-locking body 521 and the elastic body 522 are limited by the limiting member 55 to effectively prevent the self-locking body 521 and the elastic body 522 from falling off, so that the self-locking body 521 and the elastic body 522 can be stably installed on the mounting body 51. On the other hand, the movement of the self-locking body 521 can be limited by the limiting member 55 to improve the stability of the movement of the self-locking body 521.

[0071] The limiting member 55 may be a limiting plate or a limiting frame, or may be other limiting structural members, which are not specifically limited herein.

[0072] In some embodiments, the lock body assembly 2 is provided with a stopper 517 , which cooperates with an edge stopper of the exposure hole 12 to limit the amount by which the lock body assembly 2 pops out of the exposure hole 12 .

[0073] Specifically, a stop portion 517 is provided on the outside of the mounting body 51. During the movement of the mounting body 51, the stop portion 517 cooperates with the edge stop of the exposure hole 12 to limit the amount by which the mounting body 51 and the cover body 4 pop out of the exposure hole 12, effectively preventing the cover body 4 from popping out of the exposure hole 12 too much, thereby affecting the user experience.

[0074] Continue to refer to Figures 1 to 8The lock cylinder body 5 includes a mounting body 51, the cover body 4 is rotatably connected to the mounting body 51, and the pop-up assembly 3 includes a fixing member 31 and a locking member 32. The fixing member 31 is connected to the housing 1, the mounting body 51 is movably connected to the fixing member 31, and the locking member 32 is mounted on the fixing member 31. The mounting body 51 is provided with a fastening portion 518, and the locking member 32 is used to lock the fastening portion 518 in the locked state or release the fastening portion 518 in the unlocked state to lock or unlock the mounting body 51.

[0075] The fixing member 31 includes a fixing plate 311, with a centrally located escape hole 3111 for the passage of the front locking plate 54. Mounting holes 3112 are provided on both sides of the fixing plate 311. Two locking members 32 are provided, each correspondingly fixedly mounted in the two mounting holes 3112. Two fastening portions 518 are provided, one on each side of the mounting body 51. The two fastening portions 518 engage with the two fastening members to stably lock the mounting body 51, enhancing the locking force of the mounting body 51 and effectively preventing the mounting body 51 from accidentally falling off due to a violent impact or significant external force.

[0076] The fastening portion 518 may be a hook or a block, and the locking member 32 may be a push-type ball switch or an elastic locking plate structure. It is understood that the locking member 32 may also be other structural members that have the function of locking or unlocking when subjected to external forces, as long as they can achieve locking or unlocking the mounting body 51. Detailed description is not provided here.

[0077] In addition, when the fastening portion 518 is fastened or disengaged with the fastening piece, a sound is generated to alert the user, thereby improving the performance of the smart door lock 100 and enhancing the user experience.

[0078] Continue to refer to Figures 1 to 8 The lock core body 5 also includes a self-locking member 52, which is connected to the mounting body 51. The self-locking member 52 is used to lock or unlock the cover body 4. The self-locking member 52 is provided with an oblique push portion 5212, that is, the oblique push portion 5212 is formed on the side wall of the self-locking member 521 facing the fixed plate 311. The fixed member 31 is provided with an oblique top portion 3131, and the oblique push portion 5212 slides with the oblique top portion 3131 to lock or unlock the cover body 4. The oblique top portion 3131 is used to restrict the self-locking member 52 from unlocking the cover body 4 when the mounting body 51 is in the locked state. The oblique top portion 3131 is used to gradually release the restriction on the self-locking member 52 when the mounting body 51 is in the unlocked state, so that the self-locking member 52 can unlock the cover body 4.

[0079] When the lock catch 32 locks the mounting body 51, the inclined top portion 3131 presses against the inclined push portion 5212 to restrict the self-locking body 521 from driving the locking pin to exit the self-locking slot 412. When the lock catch 32 releases the lock on the mounting body 51, the inclined push portion 5212 slides with the inclined top portion 3131 and gradually moves away from the inclined top portion 3131, so that the inclined top portion 3131 gradually releases the restriction on the inclined push portion 5212. After the inclined push portion 5212 is completely separated from the inclined top portion 3131, the self-locking body 521 drives the locking pin to exit the self-locking slot 412 under the action of the elastic body 522, thereby enabling the cover body 4 to be promptly unfolded after extending out of the exposure hole 12 to expose the lock core portion 531, thereby performing an emergency unlocking operation.

[0080] The self-locking member 52 includes a self-locking body 521, which is movably connected to the mounting body 51 and has an inclined sliding wall facing the fixed member 31 to form an inclined push portion 5212. The fixed member 31 includes a guide body 313, one end of which is fixedly connected to the fixed plate 311. The end of the guide body 313 away from the fixed plate 311 has an inclined mating wall facing the mounting body 51 to form an inclined top 3131. The inclined sliding wall slidably engages with the inclined mating wall.

[0081] The inclined sliding wall and the inclined matching wall can achieve both pressing and sliding engagement, which is simple and effective. The inclined top 3131 can also guide the movement of the inclined push portion 5212 to improve the movement efficiency of the mounting body 51, thereby improving the efficiency of unlocking.

[0082] Continue to refer to Figures 1 to 8 The pop-up assembly 3 also includes a return member 33, one end of the return member 33 is connected to the fixing member 31, and the other end is connected to the mounting body 51. The return member 33 is used to provide a restoring force for the mounting body 51 in the unlocked state, so that the mounting body 51 can drive the cover body 4 to pop out of the revealing hole 12.

[0083] In this arrangement, the mounting body 51 compresses the return member 33 when locked by the locking member 32. When the locking member 32 unlocks the mounting body 51, the return member 33 immediately pushes the mounting body 51 in the direction away from the fixed plate 311, so that the mounting body 51 can quickly push the cover body 4 out of the exposure hole 12. After the cover body 4 pops out of the exposure hole 12, the self-locking member 52 releases the restriction on the cover body 4, so that the cover body 4 can be unfolded in time to reveal the lock core part 531.

[0084] The fixing member 31 includes a fixing plate 311 and a guide post 312. The fixing plate 311 is fixedly mounted to the housing 1, that is, the fixing plate 311 is fixedly mounted to the back shell 14. One end of the guide post 312 is connected to the fixing plate 311. The mounting body 51 is provided with a guide hole 519, through which the other end of the guide post 312 passes. The return member 33 is sleeved on the exterior of the guide post 312, with one end of the return member 33 abutting the fixing plate 311 and the other end abutting the edge of the guide hole 519.

[0085] The guide column 312 can guide the movement of the return member 33, so that the return member 33 stably pushes the installation body 51 to move, thereby improving the smoothness of the movement of the installation body 51 and improving the unlocking efficiency of the smart door lock 100.

[0086] In some embodiments, there are multiple guide posts 312, multiple return members 33, and correspondingly, multiple guide holes 519. The ends of the multiple guide posts 312 away from the fixing plate 311 pass through the corresponding guide holes 519, and the multiple return members 33 are sleeved on the corresponding guide posts 312. The multiple guide posts 312, the multiple return members 33, and the guide holes 519 can more stably drive the movement of the mounting body 51, greatly improving the stability of the movement of the mounting body 51, thereby quickly pushing the cover body 4 out of the exposure hole 12, thereby achieving rapid unlocking of the smart door lock 100 and improving the unlocking efficiency of the smart door lock 100.

[0087] The return member 33 may be an elastic structure, such as a spring, an elastic rubber sleeve, or an elastic silicone sleeve.
