Description

Technical Field

[0001] This utility model relates to the field of smart home technology, and more specifically, to a wireless power supply device. Background Technology

[0002] In the smart home field, with the development of technology and the increasing demands of users, the intelligentization of home devices has become a trend. Traditional home devices rely on wired connections for power supply, especially the connection between high-voltage and low-voltage components, typically using pin headers and sockets or FPC flexible flat cables. However, these traditional power supply methods have many limitations and technical challenges, especially in terms of installation and maintenance.

[0003] The pin header and socket connection method is widely used in the wiring of smart home devices, especially 4-inch central control screens. It transmits electrical energy through metal contact points. The advantages of this method are low cost and simple structure. However, in actual installation, extremely high precision is required. If the pin header and socket are not precisely aligned, misalignment can easily occur, leading to poor contact or even a complete lack of power. Furthermore, this connection method may loosen over long-term use due to vibration and other factors, reducing the stability and lifespan of the device.

[0004] The use of FPC (Flexible Printed Circuit) cables solves some of the inconveniences of pin header and socket connections. Their flexibility allows them to adapt to complex installation environments to a certain extent. However, FPC cables are relatively thin and easily broken during installation, especially under improper external force or repeated bending, which can lead to permanent damage. Furthermore, if the plug and socket of the FPC cable are not fully inserted, it can also cause unstable power supply, affecting the normal operation of the equipment. Utility Model Content

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] As mentioned in the background section, in the field of smart homes, with the development of technology and the improvement of user needs, the intelligentization of home devices has become a trend. Traditional home devices rely on wired connections for power supply, especially the connection between high-voltage and low-voltage components, typically using pin headers and sockets or FPC flexible flat cables. However, these traditional power supply methods have many limitations and technical challenges, especially in terms of installation and maintenance.

[0046] The pin header and socket connection method is widely used in the wiring of smart home devices, especially 4-inch central control screens. It transmits electrical energy through metal contact points. The advantages of this method are low cost and simple structure. However, in actual installation, extremely high precision is required. If the pin header and socket are not precisely aligned, misalignment can easily occur, leading to poor contact or even a complete lack of power. Furthermore, this connection method may loosen over long-term use due to vibration and other factors, reducing the stability and lifespan of the device.

[0047] The use of FPC (Flexible Printed Circuit) cables solves some of the inconveniences of connecting pin headers and sockets. Their flexibility allows them to adapt to complex installation environments to a certain extent. However, FPC cables are relatively thin and easily broken during installation, especially under improper external force or repeated bending, which can lead to permanent damage. Furthermore, if the plug and socket of the FPC cable are not fully inserted, it can also cause unstable power supply, affecting the normal operation of the equipment.

[0048] The purpose of this application is to provide a wireless power supply device to address the above problems, including a rear-mounted component, including a rear housing 1, and a first conductive structure 2 disposed inside the rear housing 1. The first conductive structure includes a first PCB board 201, a first insulating part 202 and a first coil 203 arranged in sequence. The first PCB board 201 is disposed on and in contact with the bottom wall of the rear housing. The rear housing 1 is also provided with a wiring component 3. One end of the wiring component 3 is connected to the first PCB board 201, and the other end of the wiring component 3 is connected to the power supply.

[0049] The front mounting assembly includes a front housing 4, which is detachably connected to a rear housing 1. A second conductive structure 5 is provided inside the front housing 4. The second conductive structure 5 includes a second PCB board 501, a second insulating part 503, and a second coil 502 arranged in sequence. The second PCB board 501 is located on and in contact with the bottom wall of the front housing. Under the action of the power supply, the first coil 203 generates a magnetic field and transmits it to the second coil 502, so that the magnetic field is converted into electrical energy through the second coil 502, thereby generating current in the front mounting assembly.

[0050] Specifically, such as Figures 1 to 6As shown, the wireless power supply device provided in this application includes a detachably connected front mounting assembly and a rear mounting assembly. The rear mounting assembly includes a rear housing 1 and a first conductive structure 2 disposed inside the rear housing 1. The first conductive structure 2 includes a first PCB board 201 disposed on the bottom wall of the inner wall of the rear housing 1. A first insulating part 202 is disposed on the side of the first PCB board 201 away from the bottom wall of the inner wall of the rear housing 1. A first coil 203 is disposed on the side of the first insulating part 202 away from the first PCB board 201. A primary winding module 204 is disposed on the side of the first coil 203 away from the first insulating part 202 for mounting with the first coil 203. A wiring component 3 is also disposed on the rear housing 1. One end of the wiring component 3 is connected to the first PCB board 201, and the other end can be connected to an external power supply.

[0051] The front mounting assembly includes a front housing 4, which is detachably connected to a rear housing 1. A second conductive structure 5 is provided inside the front housing 4. The second conductive structure 5 includes a second PCB board 501 disposed on the inner bottom wall of the front housing 4. A second insulating part 503 is provided on the side of the second PCB board 501 away from the front housing 4. A second coil 502 is provided on the side of the second insulating part 503 away from the second PCB board 501. A secondary winding module 504 is provided at one end of the second coil 502 away from the second PCB board 501. A receiving boss 505 is provided on the secondary winding module 504. The receiving boss 505 protrudes in a direction away from the second coil 502 to form a receiving space for receiving the second coil 502. Under the action of the power supply, the first coil 203 generates a magnetic field and transmits it to the second coil 502. The second coil 502 converts the magnetic field into electrical energy, thereby causing the front mounting assembly to generate current.

[0052] The rear-mounted components are detachably connected to the front-mounted components, avoiding alignment problems and poor contact issues that may occur with traditional wiring methods involving pin headers and sockets or FPC flexible cables. This not only simplifies the installation process and reduces the requirement for installation precision, but also reduces the frequency of maintenance and replacement due to poor contact, thereby lowering overall costs and improving system reliability.

[0053] The configuration of the first conductive structure 2 within the rear housing, namely the first PCB board 201, the first insulating part 202, and the first coil 203, ensures that the received 220V AC power, after safe processing, can be efficiently converted into magnetic field energy. The alternating magnetic field generated by the first coil 203 can be stably transmitted to the second coil 502 within the front housing 4. The presence of the second insulating part 503 further isolates the second PCB board 501 from the second coil 502, preventing electromagnetic interference and ensuring the efficiency and safety of the energy conversion process.

[0054] Under the action of the wiring component 3, the first coil 203 receives a stable external power supply and can generate a magnetic field of moderate strength and controllable range, thereby maximizing the energy absorption rate of the second coil 502. Compared with wired power supply, this wireless power supply method eliminates loss factors such as wire resistance and contact resistance, and improves the overall efficiency of energy conversion.

[0055] Non-contact wireless power supply avoids power failures caused by mechanical wear and aging, extending the product's lifespan. Furthermore, because wireless power supply is not limited by physical contact, users do not need to worry about damaging the power lines when installing or removing components, making product maintenance and upgrades more convenient and faster, greatly improving the user experience.

[0056] The first coil 203 and the second coil 502 do not require direct contact, enabling this wireless power supply device to operate under a wider range of conditions, such as maintaining stable power supply in humid or dusty environments. Furthermore, the detachable design of the front housing 4 and the rear housing 1 allows for the addition of more sensors, displays, or other smart modules, enhancing the system's scalability.

[0057] The application of wireless power supply technology simplifies the system integration of the 4-inch central control screen, eliminating the need for complex wiring and connection processes, reducing integration difficulty and time costs, and making the construction of smart home systems more flexible, easy to apply on a large scale and be customized.

[0058] Furthermore, the rear mounting assembly also includes a first mounting member 6 disposed on the side of the rear housing 1. The first mounting member 6 is at least partially deformable, and the mounting end of the first mounting member 6 extends away from the bottom wall of the rear housing to form a mounting protrusion.

[0059] The front mounting assembly also includes a second mounting component disposed on the side of the front housing 4. The second mounting component has a mounting groove. The second mounting component is disposed in a one-to-one correspondence with the first mounting component 6 so that when the mounting end is inserted into the corresponding mounting groove and abuts against the bottom of the mounting groove, the installation of the front housing 4 and the rear housing 1 is completed.

[0060] Specifically, the rear mounting assembly also includes a first mounting member 6 disposed on the side of the rear housing 1. The mounting section of the first mounting member 6 protrudes from the horizontal plane where the side of the front housing 4 is located to form a mounting protrusion. At least a portion of the first mounting member 6 is deformable. The front mounting assembly also includes a second mounting member disposed on the front housing 4. The second mounting member has a mounting groove. The second mounting member is configured to correspond one-to-one with the first mounting member 6. When the mounting end is inserted into the corresponding mounting groove and abuts against the bottom of the mounting groove, the installation of the front housing 4 and the rear housing 1 is completed.

[0061] The protruding design of the first mounting component 6 and the recessed structure of the second mounting component form an "insert-lock" quick installation mechanism. This design allows the connection between the front housing 4 and the rear housing 1 without additional tools or professional manual alignment, significantly simplifying the installation process and improving installation efficiency. Simultaneously, during disassembly, force can be applied to either the first mounting component 6 or the second mounting component to easily separate the front housing 4 from the rear housing 1, facilitating equipment maintenance and upgrades.

[0062] The deformable design of at least part of the first mounting component 6 means that it has a certain degree of elasticity or flexibility. When the mounting end is inserted into the groove of the second mounting component and abuts against the bottom of the groove, this deformability can compensate for manufacturing tolerances and minor displacements during installation, ensuring a tight connection between the front housing 4 and the rear housing 1, thereby improving the stability of the entire wireless power supply device structure and the reliability of the connection.

[0063] The mating design of the first mounting component 6 and the second mounting component allows the front housing 4 and the rear housing 1 to be connected through a simple alignment and plugging action. This enables users to more intuitively perceive the correctness of the connection during installation or commissioning, reducing the probability of installation errors and improving the user experience. At the same time, this design also allows for flexible installation under different environmental conditions, enhancing the product's field adaptability.

[0064] The detachable connection design, especially in the pairing of the first mounting component 6 and the second mounting component, simplifies the maintenance and troubleshooting of the wireless power supply device. During device maintenance or upgrades, there is no need to disassemble the complex electronic structure; only the external mounting components need to be addressed, thereby reducing maintenance costs and improving maintenance efficiency.

[0065] The design of the protrusion of the first mounting component 6 and the layout of the groove of the second mounting component not only realize the functional connection, but also integrate into the product appearance design, providing a cleaner and more beautiful appearance for the wireless power supply device.

[0066] The connection mechanism between the first mounting component 6 and the second mounting component avoids potential electrical fault risks in traditional wiring, such as short circuits and electric shocks, because the connection process does not involve exposed wires or electrical contact points.

[0067] Furthermore, the rear-mounted assembly also includes a plurality of first locking holes 8 disposed within the rear housing 1;

[0068] The front mounting assembly also includes a plurality of second locking holes disposed within the front housing 4, the plurality of second locking holes being configured one-to-one with the first locking hole 8. The front mounting assembly also includes a plurality of locking components that can be inserted into the plurality of second locking holes, the plurality of locking components being configured one-to-one with the plurality of second locking holes, so as to connect the first locking hole 8 and its corresponding second locking hole through the locking components.

[0069] Specifically, the remount component also includes multiple first locking holes 8, such as Figure 3 As shown, the front mounting assembly also includes a plurality of second locking holes disposed within the front housing 4, for connecting the first locking hole 8 and the corresponding second locking hole via locking components.

[0070] By providing multiple locking holes within the rear housing 1 and the front housing 4, and using locking components to connect the corresponding first locking hole 8 to the second locking hole, a multi-point fixing effect is achieved. This multi-point fixing enhances the stability of the connection between the front housing 4 and the rear housing 1, maintaining a good connection even under vibration or external force, thus preventing energy transmission interruption due to loose connections.

[0071] The addition of locking components (which may be locking bolts in this embodiment), especially their tight fit with locking holes, helps improve the sealing of the connection between the front housing 4 and the rear housing 1. This enhanced sealing reduces the possibility of external dust and moisture intrusion, which is crucial for long-term stable operation in complex environments, especially in areas with high humidity or poor air quality. This design can significantly improve the dustproof and waterproof performance of the wireless power supply device.

[0072] Furthermore, the rear housing 1 has a first sidewall 101, a second sidewall 102, a third sidewall 103 and a fourth sidewall 104 connected in sequence;

[0073] The first mounting component 6 includes a first buckle 601 disposed on the first side wall 101, a second buckle 602 disposed on the second side wall 102, a third buckle 603 disposed on the third side wall 103, and a fourth buckle 604 disposed on the fourth side wall 104.

[0074] The first buckle 601 is deformably configured so that when the front housing 4 and the rear housing 1 are installed, the first buckle 601 deforms and enters into the corresponding mounting groove to complete the installation.

[0075] Furthermore, the front housing 4 has a fifth sidewall, a sixth sidewall, a seventh sidewall, and an eighth sidewall connected in sequence;

[0076] The second mounting component includes a first groove provided on the fifth side wall, a second groove provided on the sixth side wall, a third groove provided on the seventh side wall, and a fourth groove provided on the eighth side wall.

[0077] The first groove corresponds to the first buckle 601, the second groove corresponds to the second buckle 602, the third groove corresponds to the third buckle 603, and the fourth groove corresponds to the fourth buckle 604. The second mounting component also includes a disassembly groove on the side wall of the front housing 4 that communicates with the first groove. The plane where the opening of the disassembly groove is located is perpendicular to the plane where the opening of the first groove is located.

[0078] Specifically, such as Figure 3 and Figure 4 As shown, the first buckle 601 can undergo slight deformation. A first protrusion 6011 is provided at the end of the first buckle 601, and a first locking platform 605 is provided in the first groove. When installing the front housing 4 and the rear housing 1, the second buckle 602, the third buckle 603, and the fourth buckle 604 are first inserted into the corresponding grooves. Then, the end of the first buckle 601 is aligned with the opening of the first groove, and pressure is applied to the rear housing 1, causing the first protrusion 6011 to enter the first groove and continue to move forward. The tool moves downward until the first protrusion 6011 engages with the first locking platform 605 to complete the installation. The disassembly groove is connected to the lower space of the first locking platform 605, that is, the disassembly groove is set directly opposite the first protrusion 6011. When disassembling, the tool is inserted into the disassembly groove and abuts against the first protrusion 6011. Then, an external force is applied to the first protrusion 6011, causing the first protrusion 6011 to move away from the disassembly groove until the first protrusion 6011 separates from the first locking platform 605, thus completing the disassembly.

[0079] The above setup ensures that the front and rear housing components will not separate during normal use, and can be easily disassembled using only a flathead screwdriver, making the installation and disassembly process simple.

[0080] Furthermore, a plurality of first connection holes are provided on the bottom wall of the rear housing, and a plurality of second connection holes 9 are provided on the first PCB board 201, with the plurality of first connection holes and the plurality of second connection holes 9 being provided in a one-to-one correspondence;

[0081] The rear mounting assembly also includes multiple first connectors, each of which is corresponding to a multiple first connection hole. Each first connector can be interleaved within its corresponding first connection hole so that the first PCB board 201 can be mounted on the bottom wall of the rear housing through the first connectors.

[0082] Specifically, the first connector can be a connecting bolt. By providing multiple connecting holes on the bottom wall of the rear housing 1 and the first PCB board 201, and using connecting bolts or other first connectors, precise alignment and fixation of the first PCB board 201 to the bottom wall of the rear housing 1 can be achieved. The combined use of multiple connecting holes and connectors ensures that the first PCB board 201 is firmly fixed within the rear housing 1, preventing displacement or loosening of the first PCB board 201 due to vibration or external impact.

[0083] The corresponding design of the first connecting hole and the second connecting hole 9 makes the assembly of the first PCB board 201 standardized and modular.

[0084] The first PCB board 201 is tightly connected to the bottom wall of the rear housing 1 via connectors, which helps to create a closed electromagnetic shielding environment. By reducing the leakage of electric and magnetic fields, the protection of internal circuits is enhanced, ensuring the efficiency and stability of energy transmission.

[0085] The detachable design of multiple connection holes and connectors facilitates the maintenance and upgrades of the wireless power supply device. When it is necessary to replace the first PCB board 201 or other internal components, technicians can easily remove and replace the PCB board by simply loosening the connection bolts, without damaging the entire device structure. This reduces maintenance costs and improves maintenance efficiency and user experience.

[0086] Furthermore, the first coil 203 has a plurality of first mounting positions 2031 on the side relatively close to the first PCB board 201. Each of the plurality of first mounting positions 2031 corresponds one-to-one with at least a portion of the plurality of second connecting holes 9. Each first mounting position 2031 has a first mounting thread to fix the first coil 203 onto the first PCB board 201 via a first connector; and / or,

[0087] A first adhesive layer is provided on the side of the first coil 203 that is relatively close to the first PCB board 201, so as to fix the first coil 203 on the first PCB board 201 through the first adhesive layer.

[0088] Specifically, the first mounting position 2031 can be a threaded hole with a first mounting thread. When used with a first connector (such as a screw), the first coil 203 can be securely fixed to the first PCB board 201, preventing displacement or loosening of the first coil 203 during operation due to vibration or thermal expansion and contraction. This stable connection method ensures the stability of the magnetic field strength and energy transmission efficiency during electromagnetic induction, improving the reliability and efficiency of wireless power supply.

[0089] The first coil 203 is in close contact with the first PCB board 201 through the first mounting position 2031, forming a good heat conduction path. The heat generated by the coil during operation can be quickly transferred to the first PCB board 201, and further diffused to the rear housing 1 through the first PCB board 201, and finally dissipated into the environment.

[0090] The use of the first mounting position 2031 ensures that the first coil 203 and the first PCB board 201 have a defined relative position, which helps to reduce electromagnetic interference between the first coil 203 and other electronic components of the first PCB board 201.

[0091] Furthermore, the first insulating part 202 is detachably connected to the first coil 203; and / or,

[0092] The second insulating part 503 is detachably connected to the second coil 502.

[0093] The detachable connection design allows the first insulation part 202 and the second insulation part 503 to be replaced independently of the coil when they are damaged or aged, without the need to remove or replace the entire coil assembly.

[0094] Furthermore, a plurality of third connection holes are provided on the bottom wall of the front housing, and a plurality of fourth connection holes 5011 are provided on the second PCB board 501, with the plurality of third connection holes and the plurality of fourth connection holes 5011 corresponding one-to-one.

[0095] The front mounting assembly also includes multiple second connectors, each of which is corresponding to a number of third connection holes. Each second connector can be inserted into its corresponding third connection hole to mount the second PCB board 501 onto the bottom wall of the front housing via the second connectors.

[0096] By providing multiple connection holes on the bottom wall of the front housing 4 and the second PCB board 501, and connecting the two with a second connector, the second PCB board 501 can be precisely positioned and securely fixed within the front housing 4.

[0097] The second PCB board 501 is in close contact with the bottom wall of the front housing 4 through the connector, providing an effective heat dissipation path for the second PCB board 501.

[0098] The corresponding arrangement of the third connecting hole and the fourth connecting hole 5011 allows the second PCB board 501 to be quickly positioned and fixed during assembly.

[0099] The tight connection between the second PCB board 501 and the bottom wall of the front housing 4 helps to create a closed electromagnetic shielding environment and reduce the impact of external electromagnetic interference on the internal circuitry.

[0100] Furthermore, the second coil 502 has a plurality of second mounting positions on the side relatively close to the second PCB board 501. Each of the plurality of second mounting positions corresponds one-to-one with at least a portion of the plurality of second connecting holes. Each second mounting position has a second mounting thread to fix the second coil 502 onto the second PCB board 501 via a second connector; and / or,

[0101] A second adhesive layer is provided on the side of the second coil 502 that is relatively close to the second PCB board 501, so as to fix the second coil 502 on the second PCB board 501 through the second adhesive layer.

[0102] The second mounting thread on the second mounting position, in conjunction with the second connector (such as a screw), provides a reliable way to fix the second coil. This physical connection ensures that the coil and the second PCB board 501 do not shift or vibrate during wireless power supply, maintaining the precise positional relationship required for electromagnetic induction, thereby ensuring the stability and efficiency of energy transmission.

[0103] The second coil 502 is directly fixed to the second PCB board 501 through the second mounting position, thus establishing a direct heat conduction path from the coil to the PCB board and then to the front housing.

[0104] The fixation of the second coil 502 is not limited to physical stability; the application of the second adhesive layer also provides additional electromagnetic isolation.

[0105] The detachable connection between the second coil 502 and the second PCB board 501, namely by threaded connection or adhesive layer fixation, provides convenience for disassembling the second coil 502 when maintenance or technical upgrades are required.

[0106] The use of the pre-set threads and the second adhesive layer in the second mounting position makes the assembly process of the second coil 502 and the second PCB board 501 standardized and simplified.
