[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Please see Figures 1-5 This embodiment provides an integrated intelligent door lock linkage power supply structure, including a lock body end power supply component 1 and a door frame end power supply component 2. The lock body end power supply component 1 is installed inside the lock body 3, and the lock body 3 is installed inside the door body 5. The power supply component 1 at the lock body end includes a first conductive element. The lock body 3 is equipped with a telescopic transmission component. The telescopic transmission component is provided with the first conductive element. The first conductive element is electrically connected to the power supply output terminal. The power supply output terminal is used to be electrically connected to the intelligent control terminal 6. The telescopic transmission component is used to extend when the lock body 3 is locked and retract when the lock body 3 is unlocked. The lock body 3 is equipped with a beveled tongue 31, a triangular tongue 32, and a square tongue 33, which are used for locking the door. When the beveled tongue 31 and the triangular tongue 32 are compressed simultaneously, the square tongue 33 pops out. The retractable transmission component is the square tongue 33 of the lock body 3, which has an embedded hole. The first conductive component includes a first positive contact post 11 and a first negative contact post 12. The outer walls of the first positive contact post 11 and the first negative contact post 12 are covered with a first insulating colloid 13 and installed in the embedded hole. The power output terminal includes a power output cable 14. One end of the first positive contact post 11 and the first negative contact post 12 are connected to the power output cable 14, which is electrically connected to the intelligent control terminal 6. The door frame end power supply component 2 is installed on the fixed part of the door frame 4. The door frame end power supply component 2 is positioned corresponding to the lock body end power supply component 1 to achieve docking. The door frame end power supply component 2 includes a second conductive element. An elastic telescopic component is installed in the fixed part. The elastic telescopic component is connected to the second conductive element. The elastic telescopic component is used to drive the second conductive element to elastically extend and retract to adaptively adjust the contact distance. The second conductive element is connected to a power supply input terminal, which is used to electrically connect to an external power source. The intelligent control terminal 6 includes a front panel control terminal 61 and a rear panel control terminal 62. The front panel control terminal 61 is located on the outside of the door 5 and integrates multiple interactive modules, including a digital password input keypad, allowing users to unlock the door by entering a preset password; it also features an IC card sensing area, supporting contactless IC card reading and verification, providing users with a convenient card-swipe unlocking method; and it integrates a biometric module, which completes identity authentication by collecting and comparing the user's biometric information, further enhancing the security and intelligence level of the lock. The rear panel control terminal 62 is installed on the inside of the door 5 for internal operation and settings, and is equipped with a mechanical knob or an emergency unlock button. The lock is manually unlocked mechanically. Both the front panel control terminal 61 and the rear panel control terminal 62 are electrically connected to the power supply output cable 14. The front panel control terminal 61 is used for intelligent control of the lock body 3 opening, and the rear panel control terminal 62 is used for the lock body 3 opening or closing. The second conductive component includes a second positive contact post 21 and a second negative contact post 22. The outer walls of the second positive contact post 21 and the second negative contact post 22 are covered with a second insulating colloid 23. One end of the second positive contact post 21 and the second negative contact post 22 is connected to the power supply input cable 24. The elastic telescopic component is connected to the second positive contact post 21 and the second negative contact post 22. The power supply input cable 24 is electrically connected to an external power source. When the door is closed and locked, the retractable transmission component extends to connect the first conductive element and the second conductive element and form an electrical connection; when the door is opened and unlocked, the retractable transmission component retracts, causing the first conductive element and the second conductive element to separate, thereby disconnecting the power supply path.

[0020] Specifically, this invention installs a lock body end power supply component 1 inside the lock body 3 and an elastic telescopic component inside the fixed component in the door frame 4. The elastic telescopic component is connected to a second conductive element, and the distance between the second conductive element and the first conductive element is adaptively adjusted by the elastic telescopic component to ensure stable connection between the second conductive element and the first conductive element. When the door 5 is closed, the square tongue 33 pops out when the latch 31 and the triangular tongue 32 of the lock body 3 are compressed simultaneously. The square tongue 33 is then embedded into the corresponding slot in the door frame strike plate, so that the first positive contact post 11 and the second positive contact post 21 in the square tongue 33 are coaxially connected, and the second negative contact post 22 and the second negative contact post 22 are coaxially connected, forming an electrical path and allowing the power supply output line to... Cable 14 connects electrical energy to the intelligent control terminal 6, continuously powering the door lock fingerprint module, main control chip, and other intelligent devices on the door body 5, forming a power supply system that does not require a built-in power supply. When the lock body 3 is unlocked through the intelligent control terminal 6, the first and second conductors separate, cutting off the circuit. This invention solves the problem of short battery life. Furthermore, the power input cable 24 and power output cable 14 are respectively built into the door frame 4 and the door body 5, avoiding external exposure of the wiring. The power supply triggering of the first and second conductors is synchronized with the locking action of the square tongue 33 of the lock body 3, eliminating the need for an additional drive mechanism. The overall structure of the device is simple, highly reliable, and has good performance.

[0021] In this invention, the outer walls of the first positive contact post 11 and the first negative contact post 12 are covered with a first insulating colloid 13, and the outer walls of the second positive contact post 21 and the second negative contact post 22 are covered with a second insulating colloid 23. This provides insulation between the first positive contact post 11, the first negative contact post 12, the second positive contact post 21, and the second negative contact post 22 and the lock body 3 and the door frame. Furthermore, the power input cable 24 is connected to a low-power DC / DC regulator (such as the IU5510 series), with a static current <3μA. The overall safety of the device is high. All 23 are made of high-temperature and corrosion-resistant silicone rubber, which ensures good insulation performance and has a certain degree of elasticity. It can play a buffering role when the first conductor and the second conductor are connected, reducing mechanical wear and extending the service life of the contact post. The hidden contact design of the first positive contact post 11, the first negative contact post 12, the second positive contact post 21 and the second negative contact post 22 achieves a seamless "locking = power-on" experience without affecting the appearance of the door body 5 and the mechanical performance of the door lock. The battery-free design reduces the later maintenance cost, and the low-voltage power supply + multiple insulation ensures a high safety factor.

[0022] In this embodiment (not shown in the figure), the first positive electrode contact post 11 and the first negative electrode contact post 12, which are covered with the first insulating colloid 13, are fixed in the embedded hole by interference fit or snap-fit ​​connection.

[0023] Specifically, the first positive contact post 11 and the first negative contact post 12 are fixed in the embedding hole by an interference fit or a snap-fit ​​connection. The interference fit means that the outer diameter of the first positive contact post 11 and the first negative contact post 12 is slightly larger than the inner diameter of the embedding hole. During assembly, a certain external force is applied to force the contact post into the embedding hole, and the friction generated by the elastic deformation of the material is used to achieve a stable fixation. This method of connection is tight and not easy to loosen, and can effectively resist the vibration during the opening and closing of the door 5. The snap-fit ​​connection is provided with a snap protrusion on the outer wall of the contact post, and a corresponding slot is opened on the inner wall of the embedding hole. When the contact post is inserted into the embedding hole to a specific position, the snap protrusion engages with the slot to form a mechanical limit. The installation is convenient and the disassembly is convenient, which facilitates the later maintenance or replacement of the contact post. Both the interference fit and the snap-fit ​​connection can ensure that the first positive contact post 11 and the first negative contact post 12, which are covered with the first insulating colloid 13, remain stable in the embedded hole, avoiding displacement of the contact post or poor contact due to frequent movement of the door body 5, thereby ensuring the reliability of the entire device's power supply system.

[0024] In this embodiment, as Figure 4 and Figure 5 As shown, the fixing component includes a door frame buckle 25, a door frame buckle box 26 is fixedly connected to the door frame buckle 25, the door frame buckle 25 is fixedly connected to the door frame 4, and the door frame buckle box 26 is embedded in the door frame 4. An elastic telescopic component is installed in the door frame buckle box 26.

[0025] Specifically, multiple slots are provided on the door frame latch plate 25. These slots match the beveled tongue 31, triangular tongue 32, and square tongue 33 of the lock body 3, allowing them to engage with the door frame latch plate 25 and lock the door 5 and the door frame. During the closing process of the door 5, the beveled tongue 31 automatically retracts via the beveled surface of the corresponding slot on the door frame latch plate 25. After the door 5 is fully closed, it pops out under the action of the spring 28 inside the lock body 3 and engages with the slot, achieving initial locking of the door 5 and preventing accidental opening. The triangular tongue 32, in the locked state of the door 5, then... To further enhance the stability of the lock, its unique triangular structure can form a tight fit with the inner wall of the slot, effectively resisting external impacts. The square tongue 33, as the main lock tongue, extends when the user operates the lock body 3 with a key or handle, and extends into the square slot of the door frame latch plate 25, providing a high-strength anti-theft lock and ensuring that the door body 5 cannot be easily pried open when locked. The precise layout of multiple slots is adapted to the structural design of each lock tongue of the lock body 3, together forming a reliable mechanical locking system between the door body 5 and the door frame 4, ensuring the security and stability of the door body 5 when locked. The door frame latch box 26 is equipped with an elastic telescopic component.

[0026] In this embodiment, as Figure 5As shown, the elastic telescopic assembly includes a telescopic plate 29 with a limiting hole. A second positive contact post 21 and a second negative contact post 22 are fixedly connected to the telescopic plate 29. A limiting rod 27 is welded inside the door frame buckle box 26, and a spring 28 is sleeved on the limiting rod 27. The telescopic plate 29 is connected to the limiting rod 27 through the limiting hole and abuts against the spring 28. The telescopic plate 29 moves in a limited direction along the axis of the limiting rod 27 to drive the second positive contact post 21 and the second negative contact post 22 to elastically extend and retract, so as to adaptively adjust the contact distance.

[0027] Specifically, when the door 5 is closed, the latch 31 and the triangular latch 32 of the lock body 3 are triggered by force, and the square latch 33 drives the first positive contact post 11 and the first negative contact post 12 to engage inside the door frame latch plate 25, allowing the first positive contact post 11 and the first negative contact post 12 to contact the second positive contact post 21 and the second negative contact post 22, and push the telescopic plate 29. The telescopic plate 29 will move into the door frame latch box 26 along the axis of the limit rod 27. At this time, the spring 28 is compressed, and the second positive contact post 21 and the second negative contact post 22 fixed on the telescopic plate 29 also move accordingly, so that the second positive contact post 21 and the second negative contact post 22 adaptively adjust the contact distance. The rebound force of the spring 28 will cause the telescopic plate 29 to carry the second positive contact post 21 and the second negative contact post 22. The first positive contact post 11 and the first negative contact post 12 are in close contact to ensure stable circuit connection. When the square tongue 33 retracts and the pushing force on the telescopic plate 29 disappears, the spring 28 will push the telescopic plate 29 to reset, so that the second positive and negative contact posts return to their initial positions, waiting for the next locking action. The setting of the limit rod 27 not only provides precise guidance for the movement of the telescopic plate 29, preventing it from deviating or jamming during movement, but its top limit structure can also effectively limit the maximum movement distance of the telescopic plate 29, avoiding damage to the spring 28 due to excessive compression. The entire elastic telescopic assembly achieves flexible adjustment of the contact distance through the ingenious cooperation of the mechanical structure, ensuring the reliability and stability of electrode contact during the locking process of the door 5, thereby improving the stability of power supply to the intelligent control terminal 6.

[0028] In this embodiment (not shown in the figure), the first positive electrode contact post 11 and the first negative electrode contact post 12 are in contact with one end of the second positive electrode contact post 21 and the second negative electrode contact post 22 by surface contact, point contact or line contact.

[0029] Specifically, when the first positive contact post 11 and the first negative contact post 12 are in surface contact with one end of the second positive contact post 21 and the second negative contact post 22, the end of the contact post is designed as a planar structure. This disperses the current through a larger contact area, reducing contact resistance and making it suitable for high-current transmission scenarios, effectively reducing heat generation. When the first positive contact post 11 and the first negative contact post 12 are in point contact with one end of the second positive contact post 21 and the second negative contact post 22, the end of the contact post is processed into a hemispherical or conical shape. Stable contact is achieved through the high pressure at the tip, which is more suitable for applications with limited space or requiring frequent insertion and removal. It is applicable and can quickly realize circuit switching; the first positive contact post 11 and the first negative contact post 12 are in line contact with the second positive contact post 21 and the second negative contact post 22 at one end. Usually, the contact is between a cylindrical surface and a plane or between cylindrical surfaces. The length of the contact line can be adjusted according to the design requirements, taking into account both contact stability and structural compactness. It performs well in some structures with high requirements for contact reliability and certain limitations on installation space. The present invention can select a suitable contact method according to the specific current load, installation space and usage frequency of the smart door lock to ensure the effectiveness and durability of the electrode contact.

[0030] In this embodiment (not shown in the figure), the surfaces of the first positive electrode contact post 11, the first negative electrode contact post 12, the second positive electrode contact post 21, and the second negative electrode contact post 22 are all coated with an anti-oxidation coating.

[0031] Specifically, the anti-oxidation coating can be made of metals with good chemical stability, such as nickel, gold, and silver, and uniformly applied to the surface of the contact post through processes such as electroplating or chemical plating. The nickel plating not only effectively isolates the contact post substrate from corrosive media such as air and moisture, preventing oxidation and corrosion of the base metal, but also improves the surface hardness and wear resistance of the contact post, extending its service life. The gold plating, with its excellent chemical inertness and conductivity, ensures that the contact post maintains good conductivity throughout long-term use, effectively preventing oxide layer formation and maintaining stable contact resistance even in humid or slightly corrosive environments. The silver plating has extremely high conductivity, further reducing contact resistance and improving current transmission efficiency, while its anti-oxidation capabilities also meet the requirements of general operating environments. By applying an anti-oxidation coating to the surface of the contact post, the reliability and stability of electrode contact can be significantly enhanced, reducing problems such as poor contact and increased resistance caused by oxidation, thereby ensuring the continuous normal operation of the smart door lock circuit system.

[0032] In this embodiment (not shown in the figure), the voltage range of the external power supply is 5V-24V.

[0033] Specifically, the external power supply design supports a wide voltage input from 5V to 24V, which can flexibly adapt to the power supply needs of different scenarios. The wide voltage range design not only enhances the instrument's versatility and environmental adaptability, but also reduces the dependence on specific power supply specifications, making it convenient for users to flexibly choose the power supply method according to actual conditions.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
