Description

Technical Field

[0001] The utility model relates to the technical field of locks, and in particular to a lock panel structure and an electronic door lock. Background Art

[0002] An electronic door lock is a security product that electronically controls the door lock switch. It uses technologies such as programmable memory and data reading devices to achieve the functions of unlocking and locking. However, many electronic door locks still retain a mechanical lock cylinder as a backup unlocking method when they are designed to prevent situations such as the door being unable to open due to electronic system failure or battery exhaustion.

[0003] Some electronic door locks set the lock core hole on the front of the electronic lock panel, but due to the existence of the handle and the limited setting positions provided by the panel, the lock core hole is often blocked by the handle, which makes it extremely inconvenient for users to operate the door lock through the mechanical lock core. If a through hole is opened at the position of the handle corresponding to the lock core hole to avoid the key, it will seriously affect the aesthetics of the electronic door lock. In addition, since the key is required to pass through the handle through hole, the length of the key handle will be greatly increased, which is not conducive to the user's daily carrying and storage. Utility Model Content

[0004] The purpose of the embodiments of the present utility model is to provide a lock panel structure and an electronic door lock, which can solve the above-mentioned problems existing in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] In a first aspect, a lock panel structure is provided, comprising:

[0007] The panel body is provided with a lock core hole;

[0008] A limit baffle is movably provided on the panel body, and the limit baffle can move relative to the panel body to a locking position or a releasing position; when the limit baffle is in the locking position, the limit baffle blocks the lock core hole and locks the handle of the lock on the panel body; when the limit baffle is in the releasing position, the limit baffle is staggered with the lock core hole and releases the handle of the lock on the panel body.

[0009] As an optional embodiment, a first limiting portion is provided on one side of the limiting baffle, and the first limiting portion moves along with the limiting baffle between the locking position and the releasing position;

[0010] The lock panel structure also includes:

[0011] The limiting component is provided on the panel body, and the limiting component is formed with a second limiting portion located in the movement path of the first limiting portion, and the second limiting portion can constrain the first limiting portion to a locked position.

[0012] As an optional embodiment, the first limiting portion is configured as a convex edge protruding from a side edge of the limiting baffle;

[0013] The limiting component is configured as a limiting spring sheet, and the second limiting portion is configured as a convex portion integrally formed with the limiting spring sheet and protruding toward the limiting baffle. The convex portion is located on the movement trajectory of the convex edge, so that the first limiting portion acts on the second limiting portion when passing through the second limiting portion.

[0014] As an optional embodiment, an operating portion is provided on the limit baffle, and the limit baffle can move relative to the panel body under the drive of the operating portion;

[0015] An operation hole is opened on the panel body, and the operation part is exposed to the outside of the panel body through the operation hole.

[0016] As an optional embodiment, the operation hole upper cover is provided with a dust cover, and the dust cover is detachably connected to the panel body.

[0017] As an optional embodiment, the limiting baffle further defines a limiting hole and an avoidance hole, wherein the avoidance hole is located on one side of the limiting hole and is connected to the limiting hole;

[0018] When the limit baffle is in the locking position, the limit baffle constrains the rotation of the lock handle through the limit hole. When the limit baffle is in the releasing position, the limit baffle releases the constraint on the lock handle through the avoidance hole.

[0019] As an optional implementation, the limit baffle and the panel body are guided and matched by a first guide structure and a second guide structure.

[0020] As an optional embodiment, the first guide structure is configured as a guide hole penetrating the limit baffle, and the guide hole is extended along the movement direction of the limit baffle between the locking position and the release position;

[0021] The second guide structure is configured as a positioning post protruding from the panel body, and at least a portion of the positioning post is movably connected to the guide hole.

[0022] In a second aspect, an electronic door lock is provided, comprising:

[0023] The lock panel structure according to the first aspect;

[0024] A sealing plate is mounted on the panel body and enclosed with the panel body to form a hollow installation cavity, and the limit baffle is located in the installation cavity;

[0025] A handle, one end of which extends into the mounting cavity through the panel body and is rotatably connected to the panel body. When the limit baffle is in a locked position, the limit baffle restricts the rotation of the handle.

[0028] The limit baffle is provided with a fourth limit portion adapted to the structure of the third limit portion. When the limit baffle is in the locked position, the fourth limit portion and the third limit portion are limitedly matched along the rotation direction of the rotating shaft to limit the rotation of the handle.

[0029] The beneficial effects of the utility model are as follows: the lock panel structure is simple and reliable; when the limit baffle is in the locked position, the limit baffle can block the lock core hole, thereby protecting the mechanical lock core, reducing the time the mechanical lock core is exposed to the outside of the panel body, and extending the service life of the electronic door lock; and when the limit baffle is in the released position, the limit baffle can allow the mechanical lock core to be exposed to the outside of the panel body, ensuring that the mechanical lock core can be operated normally;

[0030] At the same time, the limit baffle also locks the lock handle in the locked position, allowing the electronic door lock to provide a stable force application position during normal use. In addition, the limit baffle unlocks the handle in the release position, so that when the user needs to operate the door lock through the mechanical lock cylinder, the lock handle can rotate relative to the panel body, freeing up space in front of the lock cylinder hole for the key, which is convenient for user operation. The handle does not need to be opened with a through hole, which ensures the structural integrity and aesthetics of the electronic door lock, and makes the electronic door lock suitable for the operation of keys of normal size, meeting the daily storage and carrying needs of keys.

DETAILED DESCRIPTION

[0040] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention are described in further detail below. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0041] In the description of this utility model, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0042] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0043] An electronic door lock is a security product that electronically controls the door lock switch. It uses technologies such as programmable memory and data reading devices to achieve the functions of unlocking and locking.

[0044] There are many types of electronic door locks, which can be divided into multiple types according to different classification standards. For example, according to their functions, they can be divided into smart door locks, password locks, fingerprint locks, face recognition locks, palm vein recognition locks, etc. In addition, there are some special types of electronic door locks, such as smart door locks with visual cat eyes, surveillance capture and other functions.

[0045] Many electronic door locks are designed to retain a mechanical lock cylinder (a multi-finger mortise lock, which is generally unlocked by inserting a key and turning it) as a backup unlocking method to prevent the door from being opened when the electronic system fails or the battery is exhausted. In some high-end electronic door locks, the mechanical lock cylinder and the electronic system may also be combined to form a double verification mechanism.

[0046] This means that when using a smart door lock, users still need to carry a mechanical key as a backup, which increases the burden of carrying a key. Therefore, the user experience of the electronic door lock depends in part on the portability of the key. Some electronic door locks place the lock cylinder hole on the front of the electronic lock panel. However, due to the presence of the handle and the limited mounting space available on the panel (and the need to accommodate other components inside the lock housing), the lock cylinder hole is often obscured by the handle, making it extremely inconvenient for users to operate the door lock through the mechanical lock cylinder. Furthermore, if the handle is provided with a hole corresponding to the lock cylinder hole to avoid the key, the aesthetics of the electronic door lock will be seriously affected. Furthermore, the key handle will be significantly longer due to the need to pass through the handle hole, making it difficult for users to carry and store it daily. If the lock cylinder hole is located away from the handle, such as at the bottom of the lock housing, the user will need to squat to operate the mechanical lock cylinder, which is also inconvenient.

[0047] In addition, since the mechanical lock cylinder is exposed to the door lock surface for a long time and is used less frequently, it is easy for dust to accumulate or rust, affecting its normal use.

[0048] In view of this, the present embodiment provides a lock panel structure, which provides a limit baffle for unlocking the handle on the panel body, so that the handle can meet the daily pulling requirements of the electronic door lock. When a mechanical lock core is required to unlock the door, the handle can also leave enough operating space in front of the lock core hole, thereby solving a series of technical problems mentioned in the above background technology.

[0049] Please refer to the instruction manual Figure 3-Figure 6 The lock panel structure includes a panel body 11. The panel body 11 can be used as a part of the lock shell 10 in the application of the electronic door lock. It not only protects the internal structure and electronic components of the electronic door lock, but also has a decorative and beautifying function.

[0050] The panel body 11 of this embodiment serves as the front panel of the lock shell 10 in the application of the electronic door lock, that is, the side panel structure of the electronic door lock directly facing the user. It is the main interface for the user to operate the lock, such as entering a password, fingerprint verification, etc. The design of the panel body 11 often also focuses on user experience and aesthetics, and will be equipped with components such as a touch screen, buttons, and indicator lights. Therefore, the panel body 11 provides limited installation space for the mechanical lock core inside the lock shell 10, and the opening position provided for the lock core hole 111 is also quite limited.

[0051] Specifically, the panel body 11 is provided with a lock core hole 111 extending through two opposing sides thereof, as well as a handle hole 112 extending through two opposing sides of the panel body 11. The lock core hole 111, also known as the keyhole, allows a mechanical lock core (particularly a plug-in lock core) to pass through it and be exposed to the exterior of the panel body 11 in electronic door lock applications, ensuring that a mechanical key can be inserted into the mechanical lock core through the lock core hole 111. The handle hole 112, also known as the handle hole, is used to allow a handle 50 (or handle) to pass through the lock and secure it within the lock, allowing the handle 50 to be rotated relative to the panel body 11 (lock housing 10) or pushed or pulled to open and close the door leaf. In addition, the size and shape of the lock core hole 111 and the handle hole 112 on the panel body 11 can be adjusted according to the design and size of the mechanical lock core and the handle 50 to ensure that the mechanical lock core and the handle 50 can be firmly installed on the panel body 11. This embodiment does not impose strict requirements and limitations on this.

[0052] Based on the above structure, the lock panel structure further includes a limit baffle 20, which is movably disposed on the panel body 11. In the application of the electronic door lock, the limit baffle 20 is disposed inside the lock housing 10 formed by the panel body 11, so that the panel body 11 provides corresponding protection for the limit baffle 20, and also avoids the limit baffle 20 affecting the aesthetics of the panel body 11 due to being disposed outside the lock housing 10. It should be noted that in this embodiment, the limit baffle 20 has two main functions: one is to block or avoid the lock core hole 111, and the other is to lock and release the lock handle 50.

[0053] Specifically, the limiting baffle 20 can move to a locking position or a releasing position relative to the panel body 11 under the action of an external force.

[0054] When the limit baffle 20 is in the locked position, the limit baffle 20 blocks the lock core hole 111 and locks the handle 50 of the lock. The external environment of the panel body 11 and the mechanical lock core inside the electronic door lock are physically blocked by the limit baffle 20, so as to improve the physical security of the electronic door lock under normal use. At the same time, the limit baffle 20 directly covers the lock core hole 111 to form a physical barrier, thereby effectively preventing dust, impurities and other particles in the air from directly entering the lock core hole 111. The area around the lock core hole 111 reduces direct contact with the flowing air, thereby reducing the possibility of dust deposition in this area, which is beneficial to keeping the mechanical lock core clean and extending its service life. When the handle 50 of the lock is locked by the limit baffle 20, the handle 50 cannot rotate relative to the panel body 11, thereby forming a stable connection relationship between the handle 50 and the panel body 11. When the user pushes and pulls the door leaf through the handle 50, the handle 50 and the panel body 11 can directly and indirectly transmit the push and pull direction force through the limit baffle 20, and ensure that the handle 50 and the panel body 11 are relatively fixed during the pushing and pulling process. The user can push and pull the door leaf by providing a stable force point, thereby meeting the normal use requirements of the lock.

[0055] When the limit baffle 20 is in the released position, the limit baffle 20 and the lock core hole 111 are staggered and release the lock handle 50, so that the internal space of the lock shell 10 is connected to the outside of the panel body 11 through the lock core hole 111. In the application of the electronic door lock, the mechanical lock core installed in the lock shell 10 can also be exposed to the outside of the panel body 11 through the lock core hole 111. Because the handle 50 is released by the limit baffle 20, the handle 50 can be rotated relative to the panel body 11 under the action of external force. The user can also rotate the handle 50 to a position that is convenient for the user to operate the mechanical lock core, allowing the user to normally use the key to insert the lock core hole 111 and the mechanical lock core to unlock.

[0056] For example, in the application scenario of an electronic door lock, when the user needs to operate the mechanical lock core of the electronic door lock by using a mechanical key, he can apply external force to the limit baffle 20 to move the limit baffle 20 from the locked position that meets the normal use state of the electronic door lock to the released position, so that the lock core hole 111 is opened by the limit baffle 20, and at the same time, the rotation constraint of the unlocking handle 50 on the panel body 11 is unlocked, allowing the user to rotate the handle 50 to a state that is convenient for their own operation (the state in which the handle 50 avoids the area in front of the lock core hole 111), and then smoothly pass the mechanical key through the lock core hole 111 to operate the mechanical lock core. After the operation is completed, the user can pull out the mechanical key from the mechanical lock core and the lock core hole 111, and rotate the handle 50 to reset it, and then re-apply force to the limit baffle 20 to reset the limit baffle 20 from the release position to the locked position, so as to re-lock the rotation of the handle 50 while allowing the limit baffle 20 to cover the lock core hole 111, so as to facilitate the subsequent pulling of the door leaf and the normal use of the electronic door lock.

[0057] It can be understood that in the above embodiment, the limit baffle 20 should at least be configured to be able to stably remain in the locked position, so as to facilitate the user's daily use of the electronic door lock, and in some embodiments, the limit baffle 20 can also be configured to be able to stably remain in the release position when moving from the locked position to the release position, so that it can be reset to the locked position only when external force is re-applied subsequently, so as to facilitate the user to operate the mechanical lock cylinder through the mechanical key.

[0058] It is understandable that, whether it is an ordinary mechanical door lock or an electronic door lock, the lock housing 10 is in a state of being arranged in a vertical direction when it is installed on the door leaf. In a specific application scenario, such as Figures 1-6As shown, the handle 50 used in the electronic door lock also adopts a vertical handle 50 that is arranged in the same direction as the lock housing 10. Compared with the traditional horizontal handle 50, the vertical handle 50 takes advantage of the vertical arrangement of the lock housing 10. It occupies less horizontal space in the overall lock structure and is more suitable for modern home environments. However, the vertical handle 50 also occupies a relatively large amount of operating space on the front side of the panel body 11, resulting in the vertical handle 50 blocking the lock core hole 111 provided in the panel body 11. Although this design allows the lock core hole 111 to be hidden behind the vertical handle 50, which is beneficial to improving the aesthetics of the electronic door lock, it is also understood from the above content that this will have a significant impact on the user's use of the mechanical lock core. By adopting the above-mentioned limit baffle 20 that is movably arranged on the panel body 11, the aesthetics of the electronic door lock will not be affected when it is in normal use. When the mechanical lock core needs to be used to operate the electronic door lock, the lock core hole 111 (mechanical lock core) will not be blocked by the vertical handle 50, and the handle 50 does not need to be provided with a through hole, thereby ensuring the structural integrity and aesthetics of the electronic door lock, and making the electronic door lock suitable for the operation of normal-sized keys, meeting the needs of daily storage and carrying of keys, and meeting different needs under different usage conditions, thereby achieving the purpose of improving user experience.

[0059] In one embodiment, to ensure that the stopper 20 remains in the locked position during normal use of the electronic door lock, an elastic component (not shown) may be disposed between the stopper 20 and the panel body 11. This embodiment does not impose strict restrictions or requirements on the structural form of the elastic reset component; it may be a combination of one or more metal springs (such as compression springs, tension springs, torsion springs, etc.) and non-metallic springs (such as rubber springs, gas springs, etc.). The elastic component, disposed between the panel body 11 and the stopper 20, is configured to continuously apply an elastic force to the stopper 20 from the released position to the locked position. This ensures that the stopper 20 tends to remain in the locked position in the absence of any external forces, thus meeting the normal use requirements of the electronic door lock. When the user needs to operate the electronic door lock through the mechanical lock core, the user only needs to apply an external force to the limit baffle 20 that is sufficient to overcome the elastic force of the elastic component to allow the limit baffle 20 to move from the locked position to the released position, and after the subsequent operation is completed and the limit baffle 20 is released, the limit baffle 20 has the ability to automatically reset to the locked position.

[0060] As another embodiment of setting the limit baffle 20 to be able to at least remain in the locked position, please refer to the attached Figure 3-Figure 6In this embodiment, a first limiting portion 21 is provided on one side of the limiting baffle 20, and the first limiting portion 21 moves with the limiting baffle 20 between the locked position and the released position. Correspondingly, the lock panel structure also includes a limiting component 30 for constraining the position state of the limiting baffle 20 through the first limiting portion 21. The limiting component 30 is provided on the panel body 11, and the limiting component 30 is formed with a second limiting portion 31 located in the movement path of the first limiting portion 21. The second limiting portion 31 is structurally adapted to the first limiting portion 21 so that the two can form a limiting matching relationship when they are close to each other, thereby achieving the purpose of at least constraining the first limiting portion 21 (limiting baffle 20) to the locked position.

[0061] Of course, as can be seen from the above content, in some embodiments, in addition to being configured to have the function of constraining the first limiting portion 21 in the locked position, the second limiting portion 31 can also be configured to have the function of constraining the first limiting portion 21 in the released position, so as to reduce the risk of user misoperation when operating the lock using a mechanical key, and ensure that the limiting baffle 20 can still be maintained in the locked position and the released position within a certain range of external force.

[0062] Specifically, the first limiting portion 21 and the second limiting portion 31 can achieve different limiting cooperation modes by adopting different structural forms. Among them, the first limiting portion 21 and the second limiting portion 31 can adopt, but are not limited to, the following cooperation modes to realize the constraint of the limiting baffle 20 in different position states:

[0063] In the abutment fit, the first limiting portion 21 and the second limiting portion 31 achieve positioning by directly contacting and abutting against each other, thereby limiting the movement of the limiting baffle 20 relative to the panel body 11 .

[0064] Snap-fit, the first limiting portion 21 and the second limiting portion 31 can be respectively provided with snap-fit ​​and slot structures that are structurally compatible, and the snap-fit ​​and slot can realize snap-fit ​​or disengagement under a certain external force, thereby limiting the movement of the limit baffle 20 relative to the panel body 11.

[0065] The wedging method can be used to set at least one of the first limiting portion 21 and the second limiting portion 31 to a wedge-shaped structure. When the limiting baffle 20 moves, causing the first limiting portion 21 and the second limiting portion 31 to approach each other, the two are wedged with each other to form a tight limiting fit, and under the action of a certain external force, the two can be allowed to break away from the fitting relationship again, which is suitable for maintaining the position state and movement adjustment of the limiting baffle 20.

[0066] Magnetic coordination is achieved by respectively providing magnetic elements (such as magnets or electromagnets) on the first limiting portion 21 and the second limiting portion 31, and utilizing magnetic force to attract the two together, thereby realizing the restraining function of the limiting baffle 20 in different position states. Moreover, the magnetic elements can be separated from the magnetic coordination relationship under the action of a certain external force, thereby enabling the limiting baffle 20 to realize the transformation between position states.

[0067] Please continue to refer to the attached Figure 3-Figure 6 In one embodiment, the limiting component 30 is configured as a limiting spring. The limiting spring is a mechanical element that combines the limiting function and elastic characteristics. It is usually made of elastic material (such as spring steel) and has a certain stiffness and elastic deformation ability. The limiting spring is designed to provide resistance or prevent further movement in specific positions or conditions, thereby achieving the limitation of the moving parts.

[0068] It can be understood that the second limiting portion 31 located on the limiting spring piece can be set as a sheet structure integrally formed with the limiting spring piece, or it can be a limiting structure set on the limiting spring piece through secondary processing (such as welding or bonding). This embodiment does not impose strict limitations and requirements on this.

[0069] Correspondingly, the first limiting portion 21 can be set as a limiting plate portion convexly arranged on one side of the limiting baffle 20 or a limiting groove concavely arranged on one side of the limiting baffle 20, and its structure may depend on the specific structure of the second limiting portion 31 arranged on the limiting spring sheet. Alternatively, the second limiting portion 31 arranged on the limiting spring sheet may also be set to a structure matching the first limiting portion 21 according to its structural form.

[0070] Please refer to the attached Figure 3-Figure 6 In this embodiment, the first limiting portion 21 is configured as a convex edge structure protruding from the edge of one side of the limiting baffle 20, and the second limiting portion 31 is configured as a convex portion integrally formed with the limiting spring piece and protruding toward the limiting baffle 20. The convex portion is located on the movement trajectory of the convex edge, so that when the limiting baffle 20 switches between the locked position and the released position, the first limiting portion 21 can pass through the second limiting portion 31 and can act on the second limiting portion 31. In the process of the first limiting portion 21 acting on the second limiting portion 31, the limiting spring piece will be affected by the limiting baffle. The plate 20 is squeezed or pushed and elastically deformed. Within a certain pressure threshold, the limiting spring piece can block the limiting baffle 20 to ensure that it can remain in the locked position or the released position. When the pressure is greater than the corresponding threshold, the limiting spring piece can be deformed to completely avoid the limiting baffle 20, allowing the limiting baffle 20 to switch its position state. After the limiting baffle 20 realizes the position switching, the limiting spring piece can be quickly reset to constrain the limiting baffle 20 to meet the user's subsequent operation needs.

[0071] By setting the limiting component 30 as a limiting spring clip, in addition to ensuring that the limiting baffle 20 can be stably placed in the corresponding position state, the lock panel structure can also be made simpler and more compact. The limiting spring clip can replace the complex limiting mechanism, thereby simplifying the design and production process of the structure, providing more installation space for other components of the electronic door lock, improving its internal space utilization, and also facilitating the miniaturization design of the lock. In addition, since the limiting spring clip is usually designed and produced in a standardized manner, it is also beneficial to the large-scale production of electronic door locks to achieve the purpose of cost reduction.

[0072] In one embodiment, at least two spaced-apart fixing posts 117 are provided on the panel body 11. The two fixing posts 117 are spaced-apart along the movement direction of the limit baffle 20 (between the locked position and the released position) to avoid interfering with the movement of the limit baffle 20. The two ends of the limit spring are respectively fixed on the two fixing posts 117, and the second limit portion 31 on the limit spring protrudes toward the side close to the limit baffle 20. In this way, when the first limit portion 21 passes through the second limit portion 31, the second limit portion 31 will drive the limit spring to deform under the action of the first limit portion 21, and reset after deformation, thereby ensuring that the limit spring itself is stably installed while also ensuring that the limit spring can continue to provide the functions of limiting and avoiding.

[0073] Please continue to refer to the attached Figure 3-Figure 7 The position-limiting baffle 20 is located on one side of the panel body 11 and has an operating portion 22 formed thereon. Driven by the operating portion 22, the position-limiting baffle 20 can move relative to the panel body 11 (between a locked position and a released position). The specific structure of the operating portion 22 is not strictly limited in this embodiment and can be, but is not limited to, a pull hole formed in the position-limiting baffle 20, a grip portion protruding from the surface of the position-limiting baffle 20, or the like.

[0074] From the above content, it can be seen that since the limit baffle 20 is specifically arranged inside the lock shell 10 in the application of the electronic door lock, in order to facilitate the user to operate the limit baffle 20 through the operating part 22, the panel body 11 is also provided with an operating hole 113 running through its opposite sides. The operating hole 113 connects the spatial area of ​​the panel body 11 used to set the limit baffle 20 and the outside of the panel body 11, so that the operating part 22 can be exposed to the outside of the panel body 11 through the operating hole 113, providing the user with an operating space for operating the limit baffle 20 through the operating part 22.

[0075] In one embodiment, when the limit baffle 20 is in the locked position, the operating portion 22 retracts into the operating hole 113 so as to be located as a whole within the installation space provided by the panel body 11 (inside the lock shell 10); and when the limit baffle 20 is in the released position, the operating portion 22 can be configured to extend to the outside of the panel body 11 through the operating hole 113, that is, the user can push and pull the operating portion 22 to move the limit baffle 20 between the locked position and the released position, allowing the operating portion 22 to perform telescopic movement at the operating hole 113.

[0076] Of course, the operation method of the operating part 22 in this embodiment is not limited to this. During the movement of the limit baffle 20, the operating part 22 can also be located entirely within the operating hole 113 or entirely outside the operating hole 113. This embodiment does not impose strict limitations and requirements on this.

[0077] In one embodiment, in order to facilitate the operation of the limit baffle 20 , the operating portion 22 should be disposed on the movement trajectory of the limit baffle 20 .

[0078] Based on the above implementation method, please continue to refer to the attached Figure 3-Figure 7 The operating hole 113 is also covered with a dust cover 40, which is detachably connected to the panel body 11 to protect the internal components of the electronic door lock and make the electronic door lock have stronger structural integrity.

[0079] Exemplarily, the size and structure of the dust cover 40 should be set to completely cover the operating hole 113 to ensure that it can prevent dust and foreign matter from entering the interior of the lock shell 10. The assembly method between the dust cover 40 and the panel body 11 in this embodiment has no strict restrictions and requirements. It can be, but is not limited to, snap fit, threaded fit, wedging, interlocking, etc., as long as it is ensured that the dust cover 40 can be removed from the panel body 11 to expose the operating part 22 for the user to operate the limit baffle 20.

[0080] In one embodiment, in the case where the panel body 11 is vertically arranged on the door leaf along with the electronic door lock, the installation space provided by the panel body 11 in the width direction is relatively small. Therefore, in this embodiment, the limit baffle 20 is arranged to extend in the vertical direction and move in the vertical direction between the locking position and the release position. The operating part 22 can be arranged at one end of the limit baffle 20 in the vertical direction (for example, at the end of the panel body 11). Figure 3-Figure 4 The lower end shown in the figure) not only ensures the appearance integrity of the panel body 11, but also allows the user to adjust the position of the limit baffle 20 by pushing it up and pulling it down, thereby reducing the actual operation difficulty of the user.

[0081] In one embodiment, if Figure 3-Figure 6 As shown, the limit baffle 20 is also provided with a limit hole 23 and an avoidance hole 24. In this embodiment, the openings of the limit hole 23 and the avoidance hole 24 are both arranged toward the side of the panel body 11 where the lock core hole 111 and the handle hole 112 are provided, and the limit hole 23 and the avoidance hole 24 are not necessarily through holes passing through the opposite sides of the limit baffle 20. They can be countersunk holes arranged on the limit baffle 20.

[0082] The avoidance hole 24 is located on one side of the limiting hole 23 and is connected to the limiting hole 23. Generally, the structure of the limiting hole 23 is configured to match the structure of the rotating shaft 52 of the handle 50 in the lock, so that the rotating shaft 52 of the handle 50 can be constrained by the limiting hole 23 when placed in the limiting hole 23, and the avoidance hole 24 is configured to be a structure that can rotate when the rotating shaft 52 of the handle 50 is placed therein.

[0083] It should be understood that, since the handle 50 on the panel body 11 is in a state of movement relative to the limit baffle 20 when the limit baffle 20 moves between the locked position and the released position, in order to allow the limit hole 23 and the avoidance hole 24 to cooperate with the handle 50 in different position states of the limit baffle 20, the relative position of the limit hole 23 and the avoidance hole 24 should be set to be parallel to the movement direction of the limit baffle 20, and the limit hole 23 is located at the limit baffle 20 away from the lock. On the side of the fixed position, the avoidance hole 24 is correspondingly located on the side of the limit baffle 20 away from the release position, so that when the limit baffle 20 is in the locked position, the rotation axis 52 of the handle 50 can be located in the limit hole 23 and constrained by the limit hole 23. As the limit baffle 20 moves from the locked position to the released position, the limit hole 23 can gradually disengage from the constraint on the handle 50, allowing the avoidance hole 24 to move to a state surrounding the rotation axis 52 of the handle 50, allowing the handle 50 to rotate smoothly. Conversely, when the limit baffle 20 moves from the release position to the locked position, the avoidance hole 24 gradually disengages from the rotation axis 52 of the handle 50, and the limit hole 23 gradually enters a limiting engagement relationship with the rotation axis 52 of the handle 50.

[0084] As can be seen from the above, when the limit baffle 20 is in the locked position, the limit baffle 20 constrains the rotation of the lock handle 50 through the limiting hole 23. When the limit baffle 20 is in the released position, the limit baffle 20 releases the constraint on the lock handle 50 through the avoiding hole 24. By implementing this arrangement, the limit baffle 20 can always maintain a corresponding matching relationship with the rotating shaft 52 of the handle 50, and the rotating shaft 52 of the handle 50 can be retained within the opening structure defined by the limit baffle 20, preventing the limit baffle 20 from being unable to constrain or release the handle 50 due to the displacement of the movable position, thereby improving the stability of the lock panel structure when switching between different position states and in the corresponding position states.

[0085] Based on any of the above embodiments, the limit baffle 20 and the panel body 11 are guided and coordinated by the first guide structure and the second guide structure to constrain the movement direction of the limit baffle 20 on the panel body 11 while making the movement process of the limit baffle 20 more stable.

[0086] The first guide structure and the second guide structure described in this embodiment can adopt different structural forms according to different design requirements, including but not limited to the following forms:

[0087] Contact-type limiting: the first guide structure and the second guide structure are directly fitted together to use physical blocking to limit the movement direction of the limiting baffle 20.

[0088] The elastic element assists in limiting, and at least one of the first guide structure and the second guide structure is set as an elastic element (such as a spring, a rubber pad, etc.) so that the elastic element can absorb the impact and vibration in the non-preset direction to a certain extent, so that the limit baffle 20 can only move along the preset direction.

[0089] Sliding or rolling contact type limiting, the first guide structure and the second guide structure are in sliding or rolling contact through slide rails, rollers, etc.

[0090] The magnetic limiting mechanism is to set the first guide structure and the second guide structure as magnetic bodies, so as to utilize the attraction of the magnets to constrain the movement direction of the limiting baffle 20.

[0091] Please continue to refer to the attached Figure 3-Figure 6 The first guide structure is configured as a guide hole 25 that passes through the limit baffle 20, and the guide hole 25 extends along the movement direction of the limit baffle 20 between the locked position and the released position. Correspondingly, the second guide structure is configured as a positioning column 114 protruding from the panel body 11, and the positioning column 114 is at least partially movably connected to the guide hole 25, so that the positioning column 114 can move along the direction opened by the guide hole 25.

[0092] On the basis of the above, in order to further improve the relative stability of the limit baffle 20 and the panel body 11, in one embodiment, at least two positioning posts 114 are provided. The two positioning posts 114 are arranged at intervals along the movement direction of the limit baffle 20 and can be movably connected to the same guide hole 25, thereby constraining the movement of the limit baffle 20 in the rotation direction. It should be noted that the length of the guide hole 25 must be based on the spacing between the two positioning posts 114 plus the movement range of the limit baffle 20 to ensure that the limit baffle 20 can correctly move to the locked position and the released position. The two positioning posts 114 respectively constrain the guide holes 25, thereby avoiding the problem of the limit baffle 20 rotating relative to the panel body 11.

[0093] In another embodiment, if Figure 3-Figure 6 As shown, the guide holes 25 can also be set to multiple. In the case of setting multiple guide holes 25, the number of positioning columns 114 is consistent with the number of guide holes 25, and they are respectively connected to the guide holes 25. The positioning columns 114 are spaced apart on the panel body 11, and the guide holes 25 are spaced apart corresponding to the positioning columns 114 on the limit baffle 20, so as to ensure the relative stability of the limit baffle 20 and the positioning baffle when the positioning columns 114 are respectively matched with the guide holes 25.

[0094] In the first embodiment, please continue to refer to the attached Figure 3-Figure 6 A screw 115 is provided on the positioning column 114. The screw head size of the screw 115 and the diameter of the end of the positioning column 114 are both larger than the width of the guide hole 25. In this way, when the screw 115 is screwed to the positioning column 114 through the guide hole 25, the positioning column 114 and the screw head of the screw 115 can cooperate to constrain the freedom of movement of the limit baffle 20 in the front and rear directions, ensuring that it can stably move along the preset movement direction.

[0095] On the basis of the above embodiment, an elastic pad 116 can be provided between the screw head of the screw 115 and the limit baffle 20, and / or between the limit baffle 20 and the positioning column 114 to reduce the movable gap of the limit baffle 20 in the front and rear directions, thereby improving the stability of the limit baffle 20 in the corresponding position state, and effectively reducing the vibration and jamming of the limit baffle 20 during movement, thereby improving the user's operating experience.

[0096] Please refer to the instruction manual Figure 1-Figure 7 This embodiment also provides an electronic door lock. From the above content, it can be seen that the electronic door lock adopts the lock panel structure as described in any of the above embodiments, and on this basis, the electronic door lock also includes a sealing plate 12. The sealing plate 12 is installed on the panel body 11 to cooperate with the panel body 11 to form a lock shell 10. A hollow installation cavity 13 is formed in the lock shell 10 formed by the two. The limit baffle 20 is located in the installation cavity 13 and is movably connected to the panel body 11.

[0097] In addition, the electronic door lock also includes a handle 50, one end of which is formed with a gripping portion 51 for the user to hold, and the other end is provided with a rotating shaft 52. The rotating shaft 52 extends into the mounting cavity 13 through the handle hole 112 and is rotatably connected to the panel body 11. When the limit baffle 20 is in the locked position, the limit baffle 20 locks the rotating shaft 52.

[0098] It is understood that the locking method between the limit baffle 20 and the rotating shaft 52 can be determined according to the movement mode of the limit baffle 20 and the actual design requirements of the electronic door lock. For example, the portion of the limit baffle 20 used to lock the rotating shaft 52 and the rotating shaft 52 can be set as the following structure:

[0099] The slot and the tongue cooperate with each other, and a slot and a corresponding tongue can be respectively provided between the rotating shaft 52 on the handle 50 and the limit baffle 20. When the rotating shaft 52 is in a specific position and the limit baffle 20 is in the locked position, the tongue will be stuck in the slot, thereby locking the rotating shaft 52.

[0100] Magnetic locking, matching magnetic parts are respectively arranged between the rotating shaft 52 of the handle 50 and the limit baffle 20, so that the limit baffle 20 can act on the rotating shaft 52 through magnetic attraction when it is in the locked position, thereby preventing the rotating shaft 52 from rotating.

[0101] The snap-on locking method is to provide a corresponding snap-on and a slot between the rotating shaft 52 of the handle 50 and the limit baffle 20, so as to lock the rotating shaft 52 through the snap-on fit of the two.

[0102] In one embodiment, Figure 3-Figure 6 As shown, a third limiting portion 521 is provided on the circumferential side of the rotating shaft 52, and correspondingly, the limiting baffle 20 is provided with a fourth limiting portion 231 adapted to the structure of the third limiting portion 521. When the limiting baffle 20 is in the locked position, the fourth limiting portion 231 and the third limiting portion 521 are limited and matched along the rotation direction of the rotating shaft 52.

[0103] Here, the cooperation method of the third limiting portion 521 and the fourth limiting portion 231 is not limited to the cooperation method described above. In the embodiment in which the limiting baffle 20 further defines the limiting hole 23 and the avoiding hole 24, the fourth limiting portion 231 located on the limiting baffle 20 is configured as a portion of the hole wall of the limiting hole 23, while the third limiting portion 521 is configured as a limiting wall located on at least one side of the outer periphery of the rotating shaft 52. It is understood that the limiting wall can be, but is not limited to, a planar structure, as long as it is configured as a structure that is compatible with the hole wall of the limiting hole 23. In addition, the limiting hole 23 is configured as a non-circular structure so that the rotating shaft 52 cannot rotate when the entirety of the limiting hole 23 is placed therein.
