[0036] To make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following describes this application in further detail with reference to the accompanying drawings and embodiments.

[0037] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0042] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0043] To address the technical problem in existing related technologies where the battery power is limited, requiring users to regularly monitor the battery level and replace it promptly when it is low, otherwise the door lock may fail to open due to power failure, causing inconvenience to users; therefore, this utility model embodiment provides a wireless charging smart door lock 1.

[0044] The following describes in detail the specific structure of a wireless charging smart door lock 1 provided by this utility model embodiment. As shown in Figures 1-6, the specific structure of the charging component 17 includes a housing 11, a power supply 15, a circuit board 13, and the charging component 17.

[0045] The outer casing 11 has a receiving cavity 12, and the power supply 15 and the circuit board 13 are both built into the receiving cavity 12.

[0046] Specifically, the accommodating cavity 12 provides a relatively enclosed space for the power supply 15 and the circuit board 13, effectively preventing them from being damaged by external impacts, pressure, friction, or other physical forces. For example, in daily use, the entire door lock system may be accidentally bumped or subjected to impact during installation. Therefore, the accommodating cavity 12 protects the internal power supply 15 and circuit board 13 from damage, ensuring their normal operation. Furthermore, the accommodating cavity 12 prevents dust and moisture from entering, avoiding short circuits and component damage caused by dust accumulation or moisture intrusion. This is especially beneficial in harsh environments, such as damp basements or dusty factory workshops, thus extending the lifespan of the power supply 15 and circuit board 13.

[0047] The circuit board 13 is built into the accommodating cavity 12 and is electrically connected to the power supply 15 and the control module 16 for controlling the door lock assembly.

[0048] Specifically, the power supply 15 is the energy source for the entire wireless charging smart lock 1, providing electrical power. Taking a common lithium battery pack as an example, the battery generates direct current through a chemical reaction, providing power to various components of the wireless charging smart lock 1. When the battery is installed in the wireless charging smart lock 1 and connected to the power supply 15 circuit board 13, the current output from the power supply 15 passes through the circuit lines on the circuit board 13 and is sequentially transmitted to various components that require power, such as the door locking assembly, ensuring that the door locking assembly can work normally. Moreover, the circuit board 13 has a power supply 15 management function, which can monitor and manage the power supply 15 to improve the efficiency of power utilization and protect the battery.

[0049] Furthermore, when the wireless charging smart door lock 1 is charging, the circuit board 13 can manage and control the electrical energy output by the charging component 17, including adjusting the charging current and voltage to ensure that the power supply 15 is charged with appropriate charging parameters. For example, during the charging process, the power supply 15 circuit board 13 will automatically adjust the charging current according to the charging status of the power supply 15 (such as the initial, middle, and final stages of charging) to avoid overcharging or undercharging.

[0050] As shown in Figures 1 and 2, the charging assembly 17 includes a transmitting module 171 and a receiving module 172; the transmitting module 171 is mounted on the door frame 22, and the receiving module 172 is mounted on the door panel 21. When the door panel 21 is closed, the transmitting module 171 and the receiving module 172 are positioned opposite each other; the receiving module 172 is electrically connected to the circuit board 13, and the transmitting module 171 is electrically connected to the power supply.

[0051] Specifically, the transmitting module 171 is electrically connected to an external power source (such as a mains socket via a power adapter 15) to obtain electrical energy. The power source is typically AC mains power. The transmitting module 171 has an internal power conversion circuit 15 that converts the AC power to AC power of a specific frequency and voltage suitable for wireless charging. This is generally converted to high-frequency AC power for efficient wireless energy transmission via electromagnetic induction. The converted high-frequency AC power passes through the transmitting module 171. According to the principle of electromagnetic induction, the changing current generates an alternating magnetic field around the transmitting module 171, radiating electromagnetic waves into the surrounding space and forming an electromagnetic field capable of transmitting energy. This field transmits electrical energy as a magnetic field, providing an energy source for the receiving module 172. As shown in Figure 5, when the door panel 21 is closed, the receiving module 172 is positioned opposite the transmitting module 171 (8mm apart), and the receiving module 172 is within the alternating magnetic field generated by the transmitting module 171. According to the law of electromagnetic induction, the receiving module 172 will induce an alternating electromotive force, thereby generating an alternating current in the receiving module 172, realizing the conversion of magnetic field energy into electrical energy. Since the receiving module 172 is electrically connected to the circuit board 13, it transmits the converted stable DC power to the circuit board 13. The circuit board 13 manages and distributes the received electrical energy. As mentioned above, according to the status of the internal power supply 15 of the wireless charging smart door lock 1 or other electrical devices, it precisely adjusts the charging current and voltage to achieve safe and efficient charging of the battery.

[0052] It should be noted that the air-to-air charging between the transmitting module 171 and the receiving module 172 is mainly achieved through magnetic field coupling. That is, when the transmitting module 171 generates an alternating magnetic field, a magnetic field region is formed in the space around it. The receiving module 172 is located in this magnetic field region. Since the coils of the transmitting module 171 and the receiving module 172 are arranged opposite to each other, the coil of the receiving module 172 can be effectively coupled to the magnetic field energy generated by the coil of the transmitting module 171.

[0053] As shown in Figures 1 and 2, in some specific embodiments, the end face of the circuit board 13 is provided with a connection terminal 131, and the receiving module 172 and the control module 16 of the door lock assembly are both electrically connected to the connection terminal 131 through conductive lines.

[0054] Specifically, the receiving module 172 is electrically connected to the connection terminal 131 on the end face of the circuit board 13 via a conductive wire. When the transmitting module 171 transmits an electromagnetic signal to the receiving module 172, the receiving module 172 converts it into electrical energy and transmits the electrical energy to the connection terminal 131 via the conductive wire. Thus, the received electrical energy is conducted as current through the conductive wire to the connection terminal 131 via the receiving module 172, and then enters the circuit board 13. Subsequently, the circuit board 13 stores the electrical energy in the power supply 15, and finally the electrical energy output by the power supply 15 is transmitted to the control module through the connection terminal 131 and the conductive wire of the circuit board 13. The circuit board 13 performs a series of processes on the received electrical energy, such as converting the AC power output from the receiving module 172 into DC power through a rectifier circuit.

[0055] It should be noted that the connector 131, as a key interface on the circuit board 13, serves a dual function of electrical connection and signal transmission. It connects the power supply 15 and the receiving module 172 to various circuits inside the power supply 15 circuit board 13, enabling the orderly transmission of electrical energy between different parts. Simultaneously, the connector 131 can also transmit control signals and status information. For example, the circuit board 13 can send control signals to the receiving module 172 through the connector 131 to adjust the operating mode or parameters of the receiving module 172; the receiving module 172 can also feed back its operating status information to the circuit board 13 through the connector 131, allowing the circuit board 13 to process the information accordingly. This ensures that the entire door lock assembly can stably obtain and effectively manage and distribute electrical energy to meet the normal operation of various functions of the door lock assembly.

[0056] In some alternative embodiments, the circuit board 13 is connected to the receiving module 172 and the power supply 15 in the following two ways.

[0057] As shown in Figure 1, in one embodiment, the connection end 131 includes a first connection end 1311 and a second connection end 1312; the first connection end 1311 is electrically connected to the receiving module 172 through a first conductive line, and the second connection end 1312 is electrically connected to the control module 16 of the door lock assembly through a second conductive line.

[0058] Specifically, after the first connection terminal 1311 transmits the received electrical energy to the circuit board 13, the circuit board 13 manages the power supply 15. Subsequently, based on the overall power consumption and battery charging status, the circuit board 13 controls the distribution of electrical energy. For example, if the power supply 15 has a low charge level, the circuit board 13 directs some electrical energy to the charging circuit to charge the power supply 15; simultaneously, another portion of the electrical energy is allocated to other circuit modules that require immediate power, such as the control module 16 of the door lock assembly, to ensure the normal operation of the entire wireless charging smart door lock 1. The second connection terminal 1312 is electrically connected to the control module 16 of the door lock assembly via a second conductive line, and is mainly responsible for transmitting control signals and status information. The control module 16 is the core control unit of the wireless charging smart door lock 1, and it needs to interact with the circuit board 13 to achieve precise control of the entire door lock assembly. For example, when a user inputs an unlocking command via a mobile app or door lock panel, the control module 16 sends a signal to the circuit board 13, indicating that power is needed for the unlocking action. At this time, after receiving the signal, the circuit board 13 adjusts the output current and voltage according to the command to provide sufficient power to the door unlocking assembly to drive the door unlocking assembly to complete the unlocking action.

[0059] As shown in Figure 2, in another embodiment, the connection end 131 is electrically connected to the control module 16 of the door lock assembly via a third conductive line, and the control module 16 is electrically connected to the receiving module 172 via a fourth conductive line.

[0060] Specifically, the receiving module 172 transmits the converted electrical energy to the control module 16 of the lock assembly via the fourth conductive line. After receiving the electrical energy, the control module 16 transmits it to the connection terminal 131 on the circuit board 13 via the third conductive line. The connection terminal 131 transmits the received electrical energy to the charging management circuit in the circuit board 13. The charging management circuit charges the power supply 15 according to its charging status using an appropriate charging algorithm. When the lock assembly needs electrical energy, the power supply 15 outputs DC current and transmits it to the circuit board 13. Then, the processed electrical energy is transmitted to the control module 16 of the lock assembly via the third conductive line through the connection terminal 131. Finally, the control module 16 controls the lock assembly.

[0061] The above two methods can be set according to the actual situation, and are not limited here.

[0062] As shown in Figures 1 and 2, in some specific embodiments, the charging assembly 17 further includes a step-down module, the receiving end of the step-down module 18 is electrically connected to the power supply, and the output end of the step-down module 18 is electrically connected to the transmitting module 171.

[0063] Specifically, the buck module operates based on the principle of a switching power supply 15, and internally includes components such as a power switch, inductor, capacitor, and control chip. When the external power supply is connected, the control chip controls the power switch to turn on and off at a certain frequency. When the switch is on, current flows through the inductor to store energy and simultaneously charges the capacitor; when the switch is off, the inductor releases energy, working with the capacitor to maintain a stable output voltage. By adjusting the ratio of the switch's on-time to off-time (duty cycle), the output voltage can be precisely adjusted to achieve the operating voltage required by the transmitting module 171. Furthermore, the buck module also has a voltage regulation function, capable of monitoring changes in the output voltage in real time.

[0064] For example, when the output voltage deviates due to load changes or input voltage fluctuations, its internal control chip will automatically adjust the duty cycle to keep the output voltage stable. Moreover, when abnormal situations occur, such as excessive load current, excessive input voltage, or excessive internal temperature of the module, its internal protection circuit will act in time to cut off the power supply or take other protective measures to prevent other related components from being damaged due to abnormal voltage.

[0065] Therefore, the stable low-voltage power processed by the step-down module provides the necessary power to the transmitting module 171. With a stable low voltage, the transmitting module 171 can operate normally and generate an alternating magnetic field, sending electromagnetic signals to the receiving module 172 located on the door panel 21 to achieve wireless charging. Thus, the close cooperation between the step-down module and the transmitting module 171 ensures the stable operation of the entire wireless charging smart door lock 1.

[0066] As shown in Figures 3 and 4, in some specific embodiments, the accommodating cavity 12 includes a first accommodating cavity 121 and a second accommodating cavity 122; the power supply 15 is disposed in the first accommodating cavity 121, the door lock assembly is built into the second accommodating cavity 122, and the circuit board 13 is detachably disposed in the second accommodating cavity 122; a communication port is provided between the first accommodating cavity 121 and the second accommodating cavity 122, and the circuit board 13 is provided with a third connection terminal 1313, which extends into the first accommodating cavity 121 through the communication port and is electrically connected to the power supply 15.

[0067] Specifically, the power supply 15 is built into the first accommodating cavity 121, and the door locking assembly is built into the second accommodating cavity 122, achieving partitioned placement of different functional components. This layout improves the utilization rate of the internal space of the wireless charging smart door lock 1, allowing for a reasonable distribution of components and facilitating installation, debugging, and maintenance. For example, the power supply 15 may generate heat; separating it from the door locking assembly and control module 16 avoids heat affecting the performance of the door locking assembly and also facilitates separate heat dissipation for the power supply 15. The connection port between the first accommodating cavity 121 and the second accommodating cavity 122 facilitates the wiring connection between the circuit board 13 and the power supply 15; for example, the third connection terminal 1313 of the circuit board 13 can extend directly into the first accommodating cavity 121 through the connection port to electrically connect with the power supply 15, making the wiring between the power supply 15 and the circuit board 13 more organized and concise, reducing the clutter of the wiring and lowering the probability of wiring failure.

[0068] It should be noted that the direct connection between the third connection terminal 1313 and the power supply 15 provides a stable electrical path for the power supply 15 to supply power to the circuit board 13. This connection method ensures the efficiency and stability of power transmission and reduces problems such as increased resistance and voltage loss that may be caused by too many connection points or too long lines.

[0069] As shown in Figures 1 and 2, in a further embodiment, the circuit board 13 is detachably provided with a cover plate 14.

[0070] Specifically, by placing the cover plate 14 on the circuit board 13, it can effectively block dust from entering the circuit board 13, prevent dust from accumulating on electronic components and circuits, avoid problems such as short circuits and poor heat dissipation caused by excessive dust, and extend the service life of the circuit board 13. On the other hand, it also plays a certain role in moisture protection, reducing the corrosion of the circuit board 13 by water in the air, preventing electronic components from getting damp and rusting, and short circuits, ensuring the stability of the circuit board 13 under different humidity environments. Furthermore, it can protect the circuit board 13 from mechanical damage such as collisions and scratches from external objects, reducing the risk of damage to electronic components and breakage of circuits due to accidental contact or external impact.

[0071] As shown in Figure 1, specifically, both the cover plate 14 and the circuit board 13 have interconnected locking holes 141; the bottom surface of the first accommodating cavity 121 has a fixing hole 1211; the charging assembly 17 also includes a locking member, which is inserted into each locking hole 141 and the fixing hole 1211.

[0072] Specifically, both the cover plate 14 and the circuit board 13 have interconnected locking holes 141. When the locking components are simultaneously inserted into each locking hole 141, the cover plate 14 can be fixed to the circuit board 13. This connection method can prevent the cover plate 14 from loosening or falling off due to vibration, collision, or other reasons, ensuring that the cover plate 14 can always protect the circuit board 13. The bottom surface of the first accommodating cavity 121 has a fixing hole 1211. The locking components are simultaneously inserted into the locking holes 141 and fixing holes 1211 of the circuit board 13, so that the circuit board 13 can be firmly fixed to the bottom surface of the first accommodating cavity 121. This arrangement ensures that the circuit board 13 is fixed in the designated position of the first accommodating cavity 121, preventing it from shifting or shaking during use, thereby ensuring the stable connection between the electronic components on the circuit board 13 and other components.

[0073] In addition, during assembly, simply place the circuit board 13 at the designated position on the bottom surface of the first accommodating cavity 121, aligning the locking hole 141 on the circuit board 13 with the fixing hole 1211 on the bottom surface of the first accommodating cavity 121. Then, place the cover plate 14 on the circuit board 13, aligning the locking hole 141 on the cover plate 14 with the locking hole 141 on the circuit board 13. Finally, insert the locking component to complete the fixing of the three components. This installation method is simple and quick, and can improve the overall assembly efficiency.

[0074] It is understood that the locking component in this embodiment of the utility model is a screw, and the fixing hole 1211 is a screw hole.

[0075] The following describes in detail the specific structure of a door body 2 provided by this utility model embodiment. As shown in Figures 5-6, the specific structure of the door body 2 includes a door panel 21, a door frame 22, and the wireless charging smart door lock 1 in the above embodiment.

[0076] The transmitting module 171 can be set at any position on both sides of the door frame 22. Correspondingly, the receiving module 172 can be set at any position on both sides of the door panel 21. It is only necessary to ensure that the transmitting module 171 and the receiving module 172 are at the same height and are set opposite to each other.

[0077] For example, as shown in Figure 6, a first mounting hole is provided on the left side wall of the door frame 22, and the transmitting module 171 is installed in the first mounting hole; correspondingly, a second mounting hole is provided on the left side wall of the door panel 21, and the receiving module 172 is installed in the second mounting hole; since the first mounting hole and the second mounting hole are at the same height, the transmitting module 171 and the receiving module 172 are opposite to each other, thus realizing wireless charging.

[0078] In a further embodiment, both the transmitting module 171 and the receiving module 172 of this utility model are provided with spring clips.

[0079] Specifically, the spring clip of the launching module 171 is elastic. When the launching module 171 needs to be installed in the first mounting hole of the door frame 22, the spring clip is first aligned with the first mounting hole, and then a certain pressure is applied to cause the spring clip to elastically deform, allowing the launching module 171 and its spring clip to enter the first mounting hole. After the spring clip enters the first mounting hole, due to its elastic restoring force, it automatically springs open and locks onto the inner wall of the first mounting hole. In this way, the launching module 171 is securely installed on the side wall of the door frame 22 through the locking action between the spring clip and the first mounting hole, ensuring that the launching module 171 will not easily fall off after installation, while also being able to be removed from the mounting hole by appropriate external force when needed, facilitating maintenance or replacement. The installation principle of the receiving module 172 is similar to that of the aforementioned transmitting module 171. That is, after the spring buckle on the receiving module 172 is aligned with the second mounting hole on the door panel 21, pressure is applied to cause the spring buckle to undergo elastic deformation and enter the second mounting hole. Then, the spring buckle is locked into the inner wall of the second mounting hole by relying on the elastic restoring force, thereby firmly installing the receiving module 172 on the side wall of the door panel 21.

[0080] By engaging the spring clips with the mounting holes, the transmitting module 171 and the receiving module 172 are accurately fixed at designated positions on the door frame 22 and door panel 21, respectively, ensuring accurate and stable relative positioning between them. Furthermore, since the transmitting module 171 is mounted on the side wall of the door frame 22 and the receiving module 172 on the side wall of the door panel 21, the spring clips can adapt to the displacement and vibration generated by the opening and closing of the door to a certain extent. The elasticity of the spring clips acts as a buffer, reducing the impact on the transmitting module 171 and the receiving module 172 caused by the opening and closing of the door panel 21, preventing the modules from loosening or being damaged due to frequent door movements, thus ensuring stability and reliability during long-term use.
