Description

Technical Field

[0001] This utility model relates to the field of wireless charger technology, and in particular to a wireless charger. Background Technology

[0002] With the popularization of wireless charging technology, wireless charging is becoming increasingly widespread. Especially since Apple Inc. released the iPhone 12 series with MagSafe in 2020, more and more wireless chargers with magnetic wireless charging capabilities have emerged. Magnetic wireless chargers are favored by some consumers due to their convenient magnetic positioning function. Currently, most existing magnetic wireless chargers adopt a fixed design, meaning the wireless charging coil and magnet assembly are relatively fixed. Once the user's device (such as a mobile phone) is magnetically positioned, its screen orientation is fixed, making it difficult to flexibly adjust according to usage needs during charging. Often, it is necessary to manually remove and reposition the device or manually adjust it, which is inconvenient for switching between landscape and portrait modes for watching videos, interrupts charging continuity, and degrades the user experience.

[0003] While rotating magnetic wireless chargers have emerged in the market, they generally suffer from complex structures, poor reliability, and limited functionality. Of particular note is that some solutions require the wireless charging coil to rotate along with the magnetic structure to achieve simultaneous rotation and charging. This not only increases the risk of internal cable tangling and the complexity of the structural design but also reduces the product's lifespan. Furthermore, it restricts the freedom of rotation angle (for example, currently common electrically rotating wireless chargers often only achieve 90° or 180° rotation, because a larger rotation angle places higher demands on the electrical connection of the wireless charging coil: issues such as power supply reliability, cable reliability, and problems with cable tangling and storage). Therefore, existing products are relatively simple in function and operation, primarily focusing on charging itself, lacking additional interactive or entertainment value, and failing to satisfy the deeper emotional needs of some users.

[0004] Therefore, the market urgently needs a magnetic rotating wireless charging solution that is more reliable in structure, more convenient to operate, and more feature-rich. It should be able to retain the precise alignment function of magnetic wireless charging and ensure stable and efficient charging, while also supporting the smooth and free rotation of the device while charging to adapt to different usage scenarios and consumer needs. Alternatively, it could serve as a rotating decompression tool to provide users with certain emotional value, or even provide a certain fun interactive experience when there is no external device to be charged.

[0046] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0047] Please see below. Figures 1-5The present invention provides a wireless charger, which specifically includes:

[0048] The outer casing 10 has an internal mounting cavity 11;

[0049] A wireless charging coil 20 is disposed on the top of the mounting cavity 11. The wireless charging coil 20 is used to charge external electronic devices through electromagnetic induction.

[0050] A magnetic housing 30 is provided above the wireless charging coil 20. The magnetic housing 30 includes a magnetic part 31 and a wireless charging panel 32. The wireless charging panel 32 is disposed above the wireless charging coil 20. The magnetic part 31 is provided with a magnet mounting part 311. A magnet assembly 33 is embedded in the magnet mounting part 311. The magnet assembly 33 is used to attract external electronic devices to the magnetic housing 30.

[0051] A drive assembly 40 is disposed inside the mounting cavity 11 and connected to the magnetic part 31. The drive assembly 40 is used to drive the magnetic part 31 to rotate relative to the outer shell 10 and / or the wireless charging coil 20.

[0052] An electronic control component (not shown in the figure) is disposed in the mounting cavity 11. The electronic control component is electrically connected to the drive component 40 and the wireless charging coil 20 and is used to control the wireless charging coil 20 and the drive component 40.

[0053] In this configuration, the magnetic suction part 31 is integrated with the wireless charging panel 32; or, the magnetic suction part 31 and the wireless charging panel 32 are separately configured, with a circular hole 312 in the middle of the magnetic suction part 31, the wireless charging panel being disposed within the circular hole 312, and the top surface of the magnetic suction part 31 being higher than that of the wireless charging panel 32.

[0054] In this embodiment, by setting a magnetic suction part 31 that can rotate independently of the wireless charging coil 20 and driving it to rotate by the driving component 40, while keeping the wireless charging coil 20 fixed, the external electronic device can be driven by the magnetic attraction and can rotate freely (around a preset axis) without restriction when it is aligned by magnetic attraction and in a state of wireless charging.

[0055] This embodiment effectively avoids the risks of cable tangling and durability issues caused by coil movement in traditional rotary charging solutions, significantly improving the reliability and safety of the wireless charging process. Simultaneously, by independently setting the magnet assembly (which has no electrical connection function) from the wireless charging coil, this embodiment allows users to retain the magnetic alignment function without disconnecting the device during wireless charging, while easily adjusting the device's orientation by rotating it via the drive component 40. This greatly enhances the convenience and user experience in scenarios such as watching videos and browsing the web. Furthermore, regardless of whether an electronic device is placed on the magnetic housing 30, the magnetic part 31 itself can rotate freely via the drive component 40, no longer limited by rotation angle or number of rotations. This provides users with more choices and greater entertainment value, thus giving the product additional fun and stress-relieving functions, expanding the application scenarios and value of the wireless charger.

[0056] It is understandable that the electronic control component can control the operation logic of the drive component 40, such as controlling it to perform uniform motion, stop motion, variable speed motion, reciprocating motion, and changing its direction of motion, thereby controlling the operating state of the magnetic suction unit 31. The electronic control component can control the drive component in various ways, such as manual adjustment switch control, touch switch, remote control switch control, photoelectric control (automatically rotating to landscape mode within a preset time after the lights are turned off), sound control, wireless transmission control, etc.

[0057] It should also be noted that in specific application scenarios, the magnetic part 31 and the wireless charging panel 32 can be integrated or set up separately, depending on the actual situation. Only the corresponding structural adaptation is required. Regardless of the setting method, the rotation function of the magnetic part 31 and the wireless charging performance will not be affected, thereby ensuring the practicality of the product while further improving its flexibility and user experience.

[0058] For example, when the magnetic part 31 is integrated with the wireless charging panel 32, the top surface of the magnetic part 31 is flush with the wireless charging panel 32 (or the top surface of the magnetic part 31 is higher than the top surface of the wireless charging panel 32), and a certain gap is reserved between the wireless charging panel 32 and the wireless charging coil 20, so as to ensure the stability of the electronic device and the uniformity of the appearance of the wireless charger, while not affecting its rotational freedom.

[0059] For example, when the magnetic suction part 31 and the wireless charging panel 32 are provided separately, a circular hole 312 can be provided in the middle of the magnetic suction part 31, and the wireless charging panel 32 can be placed in the circular hole 312. At the same time, the top surface height of the magnetic suction part 31 is set to be higher than the top surface height of the wireless charging panel 32. In this case, only the magnetic suction part 31 is driven to rotate by the driving component 40, while the wireless charging panel 32 in the circular hole 312 remains stationary. By setting the top surface height of the magnetic suction part 31 to be higher than the top surface height of the wireless charging panel 32, it is possible to prevent electronic devices placed on the magnetic suction part 31 from scratching or rubbing against the wireless charging panel 32 during rotation.

[0060] Furthermore, in specific embodiments, the magnet mounting portion 311 on the magnetic suction portion 31 can be an open magnet mounting groove, in which the magnet assembly 33 can be directly embedded or fixed by adhesive. Alternatively, it can be a closed magnet mounting cavity, in which the magnet assembly 33 is encased within the magnet mounting portion 311 through integral molding or other methods. Of course, in practical applications, the arrangement of the magnet assembly 33 is not limited to the above embodiments, and other reasonable layout forms can also be adopted. The specific arrangement can be flexibly selected according to actual needs to adapt to the requirements of different specifications of electronic devices for adsorption force and magnetic field strength.

[0061] In one embodiment, the top surface of the magnetic attraction part 31 is provided with at least one downwardly recessed first groove 313, and the first groove 313 is distributed along the circumferential direction of the magnetic attraction part 31.

[0062] Alternatively, the outer periphery of the magnetic suction part 31 is provided with heat dissipation holes for heat dissipation.

[0063] In this embodiment, a first groove 313 or a heat dissipation hole can be provided on the magnetic suction part 31 to effectively dissipate the heat generated by the electronic device and the coil during charging, thereby improving heat dissipation efficiency and ensuring the stability of device operation. The choice between providing the first groove 313 or the heat dissipation hole can be made according to different situations in specific application scenarios.

[0064] For example, when the magnetic part 31 and the wireless charging panel 32 are set separately, multiple first grooves 313 can be provided on the top surface of the magnetic part 31. Combined with the structural design that the top surface of the magnetic part 31 is higher than that of the wireless charging panel 32, the space above the wireless charging panel 32 can maintain good airflow through the first grooves 313 when the external electronic device is attached to the magnetic part 31. This facilitates heat dissipation of the external electronic device during charging, effectively preventing high temperature buildup from affecting charging efficiency or device safety. In specific application scenarios, the number, position, shape, and depth of the first grooves 313 can be designed according to actual needs to adapt to electronic devices of different sizes and shapes, while taking into account both heat dissipation efficiency and adsorption stability.

[0065] In a specific embodiment, to adapt to the structural design of the first groove 313, the magnet assembly 33 within the magnet mounting portion 311 can be configured in a distribution pattern that matches the first groove 313. For example, when the magnet assembly 33 is a ring magnet, a second groove 331 can be provided on the ring magnet at the position corresponding to the first groove 313. Of course, multiple magnets can also be provided and arranged according to the distribution pattern of the first groove 313 to ensure that the attraction force between the magnetic attraction portion 31 and the external electronic device is evenly distributed, while not affecting the rotational performance and overall structural strength of the magnetic attraction portion 31.

[0066] For example, when the magnetic part 31 and the wireless charging panel 32 are integrated, a certain gap is reserved between the wireless charging panel 32 and the wireless charging coil 20 to avoid mutual friction. To keep the top surfaces of the magnetic part 31 and the wireless charging panel 32 flush and to maintain the uniformity of the wireless charger's appearance, a ring of heat dissipation holes can be provided around the outer periphery of the magnetic part 31, thereby achieving good heat dissipation without affecting the overall appearance of the wireless charger. Similarly, the position, number, and diameter of the heat dissipation holes can be flexibly adjusted according to actual usage needs to achieve the best airflow effect. Of course, it is also possible to choose to set the height of the wireless charging panel 32 slightly lower than that of the magnetic part 31, so that the two can rotate as a whole while still maintaining the overall appearance.

[0067] It is understood that in some other embodiments, depending on the actual situation, the first groove 313 and the heat dissipation hole can be provided on the magnetic part 31 at the same time to further improve the heat dissipation effect.

[0068] In one embodiment, the drive assembly 40 includes a drive motor 41 and a transmission mechanism. The output end of the drive motor 41 is connected to the transmission mechanism, and the output end of the transmission mechanism is connected to the magnetic suction part 31.

[0069] In this embodiment, the drive motor 41 drives the transmission mechanism to operate, thereby transmitting power to the magnetic suction part 31 so that it can complete the rotation action.

[0070] In one embodiment, the transmission mechanism includes a drive gear 42, and the magnetic suction part 31 is provided with a driven gear 34 that meshes with the drive gear 42. The drive motor 41 drives the magnetic suction part 31 to rotate through gear transmission.

[0071] In this embodiment, by employing a meshing transmission method between the driving gear 42 and the driven gear 34, the power of the drive motor 41 can be efficiently and stably transmitted to the magnetic suction part 31, ensuring its smoothness and precision during rotation. Simultaneously, this transmission structure has high transmission efficiency and a small space occupancy rate, contributing to a compact design of the overall wireless charger structure and further enhancing the product's practicality and aesthetics.

[0072] In other embodiments, power transmission can also be achieved by using one or more of the following transmission structures: gears, racks, belts, couplings, chain drives, screws, threads, or worm gears, to meet the needs of different application scenarios.

[0073] In one embodiment, the magnetic attraction part 31 further includes an annular slide rail 35, the driven gear 34 is disposed on the inner wall of the annular slide rail 35, and the magnet mounting part 311 is disposed on the outer periphery or above the annular slide rail 35. The annular slide rail 35 and the driven gear 34 are coaxially arranged.

[0074] In this embodiment, the annular slide rail 35 enables the magnetic suction part 31 to achieve stable support and guidance during rotation through the slide rail structure, ensuring the smoothness and reliability of the rotation of the magnetic suction part 31. At the same time, the coaxial design of the annular slide rail 35 and the driven gear 34 ensures the coaxiality and stability of the transmission system, thereby improving the overall coordination and precision of operation.

[0075] In one embodiment, the wireless charger provided by the present invention further includes a coil mounting component 50, which is disposed above the driving component 40 and horizontally disposed within the magnetic housing (30). The top of the coil mounting component 50 is provided with a coil mounting groove 51, and the wireless charging coil 20 is embedded in the coil mounting groove 51. The coil mounting component 50 is used to fix and position the wireless charging coil 20.

[0076] In this embodiment, the coil mounting member 50 is provided so that the wireless charging coil 20 can be stably mounted inside the magnetic part 31, ensuring that the wireless charging coil 20 remains in a stable position during the rotation of the magnetic part 31, thereby coupling with the wireless receiving coil of the electronic device to be charged for wireless charging.

[0077] In one embodiment, the transmission mechanism further includes an auxiliary gear 43, which is distributed circumferentially below the coil mounting member 50 along with the driving gear 42, and the auxiliary gear 43 meshes with the driven gear 34.

[0078] The bottom of the coil mounting component 50 is provided with a clearance groove 52 for accommodating the drive gear 42 and the auxiliary gear 43. The shape of the clearance groove 52 is adapted to the contour of the drive gear 42 and the auxiliary gear 43.

[0079] In this embodiment, by providing an auxiliary gear 43 around the lower circumference of the coil mounting member 50 and having it engage with the driving gear 42, while simultaneously meshing with the driven gear 34, multi-point and uniform transmission of driving force is achieved, improving the smoothness and reliability of the rotation of the magnetic suction part 31. Furthermore, by providing a clearance groove 52 at the bottom of the coil mounting member 50 that matches the gear contour, the spatial interference problem between the gear set and the fixed coil mounting member 50 is effectively solved, ensuring smooth gear meshing and transmission while maintaining the compactness of the overall structure.

[0080] In specific application scenarios, the number and distribution of auxiliary gears 43 can be flexibly adjusted according to the transmission load and spatial layout to achieve optimal power distribution and transmission effect.

[0081] In one embodiment, a through hole 511 is provided in the coil mounting groove 51, which is used for the power control component and the wireless charging coil 20 to pass through and achieve electrical connection.

[0082] In this embodiment, by providing a through hole 511 in the coil mounting groove 51, the wires connecting the electronic control components and the wireless charging coil 20 can pass directly through the coil mounting member 50 located in the middle of the magnetic suction part 31. This effectively isolates the contact path between the wires and the rotating magnetic suction part 31 and the transmission mechanism, thereby avoiding the risk of the wires being entangled, pulled or worn due to their location around rotating components (such as the magnetic suction part 31 or gears), and significantly improving the safety and reliability of the product during long-term use.

[0083] In one embodiment, the output speed of the drive motor 41 is adjustable.

[0084] This embodiment achieves flexible control of the rotation of the magnetic suction part 31 by designing the output speed of the drive motor 41 to be adjustable. This allows the magnetic suction part 31 to rotate at different speeds or in different directions according to actual needs (such as user operation or system settings), thereby improving the adaptability and operability of the product.

[0085] In one embodiment, the wireless charger provided by the present invention further includes a sensor unit, which is used to detect preset condition information related to the wireless charger and / or external electronic devices, and to feed back the detected preset condition information to the electronic control component.

[0086] Furthermore, the electronic control component is also used to receive preset condition information fed back by the sensor unit, and to control the output speed and rotation mode of the drive motor 41 according to the preset condition information.

[0087] In this embodiment, by adding a sensor unit to detect preset condition information related to the wireless charger and / or external electronic devices, and by feeding back the detected preset condition information to the electronic control component, the electronic control component further controls the output speed of the drive motor 41 or adjusts the rotation mode of the drive motor 41 (forward or reverse or alternating forward and reverse) according to the preset condition information, thus realizing intelligent control of the rotation state of the magnetic suction part 31.

[0088] In specific embodiments, the types of preset condition information detected by the sensor unit include, but are not limited to: the placement status of external electronic devices, ambient light conditions, user interaction commands, etc. It is understood that the sensor unit can detect corresponding preset condition information by setting one or more different types of sensors according to actual needs, and trigger corresponding control logic based on the corresponding preset condition information.

[0089] In specific application scenarios, the sensor unit can be selected according to actual needs. For example, it can employ one or more of the following: infrared sensors, photoelectric sensors, touch sensors, image sensors, voice sensors, NFC, FOD sensors, and facial recognition modules, thereby detecting different preset condition information (not limited to the placement status of external electronic devices, ambient light conditions, and user interaction commands mentioned above). Furthermore, different types of sensors can be combined to achieve more accurate detection and richer control logic.

[0090] For example, an infrared sensor can be installed on the wireless charger. When the infrared sensor detects a device placed on the magnetic housing 30, it can control the drive motor 41 to reduce its speed, thereby effectively preventing the device from falling due to excessive rotation and ensuring the stability of the charging process. When the sensor detects no device placed on the magnetic housing 30, the drive motor 41 is allowed to run at a higher or unrestricted speed, thus giving full play to the fun of the free rotation of the magnetic part 31 and its decompression function. Alternatively, the operator can change the light to trigger the infrared sensor to control the drive motor 41 to rotate a preset angle (such as a preset rotation of 90 degrees, thereby switching between landscape and portrait modes).

[0091] For example, most mobile phones nowadays support the function of automatically switching to alarm clock mode (standby mode) when placed in landscape mode. This feature can be utilized by setting up a photoelectric sensor on the wireless charger. When the photoelectric sensor detects that the current environment is dark (the user is sleeping with the lights off), the device on the magnetic housing 30 can be automatically rotated to landscape mode by controlling the drive motor 41, thereby automatically turning on the standby mode (alarm clock mode) of the mobile phone, providing users with a more convenient nighttime usage experience.

[0092] In addition, touch sensors and voice sensors can be combined to achieve a more intelligent operating method. For example, regardless of whether a device is placed on the magnetic housing 30, the user can lightly touch the designated area of ​​the wireless charger or issue a specific voice command, and the drive motor 41 will automatically adjust the rotation angle or direction of the magnetic part 31 according to the information command from the sensor, thereby realizing a personalized operating experience.

[0093] Understandably, the placement and arrangement of different sensors will be flexibly determined based on the actual product structure and usage requirements. For example, infrared or photoelectric sensors can be placed below the wireless charging panel, next to the wireless charging coil 20, or installed in a mounting slot in the middle of the wireless charging coil 20. The corresponding wireless charging panel position can be set as a light-transmitting area (achieved by using transparent material or openings) so that the sensor probe can effectively sense the placement status of external electronic devices. The infrared sensor (or photoelectric sensor) can also be connected to the electronic control component 60 through the through-hole 711 for signal transmission and power supply. As for touch sensors, they can be integrated into the surface of the wireless charger's housing, while voice sensors can be built into the electronic control component 60 of the wireless charger and receive user voice commands through the microphone opening, etc.

[0094] In a specific embodiment, an angle sensor and a counter can also be set in the wireless charger. The angle sensor measures and adjusts the rotation angle or tilt angle of the device to be charged, and the counter records the number of rotations or rotation duration of the magnetic suction part 31, further enhancing the product's intelligent control capabilities or interactivity.

[0095] In one embodiment, the wireless charger provided by the present invention further includes a limiting housing 60, which is disposed on the top of the outer shell 10 and engages with the outer shell 10. A limiting hole 61 is provided in the middle of the limiting housing 60, and the shape of the limiting hole 61 is adapted to the outer peripheral shape of the magnetic housing 30.

[0096] In this embodiment, by snapping a limiting housing 60 onto the top of the outer shell 10, and providing a limiting hole 61 in the middle of the limiting housing 60 that adapts to the outer peripheral shape of the magnetic suction housing 30 (i.e., adapts to the magnetic suction part 31), the magnetic suction part 31 is limited, thereby effectively preventing the magnetic suction part 31 from shifting or slipping out during rotation, ensuring its rotational stability and coaxiality, while not affecting the free rotation function of the magnetic suction part 31 around its central axis, thus improving the reliability of the overall structure.

[0097] In specific application scenarios, the outer periphery shape of the magnetic suction part 31 can be circular, elliptical, square, etc., and the shape of the limiting hole 61 is adapted accordingly to ensure that the magnetic suction part 31 is always in a stable limiting state during rotation.

[0098] In addition, a charging interface 12 can be provided at the bottom of the outer casing 10 and a motor mounting shell 44 can be provided in the mounting cavity 11. The motor mounting shell 44 is used to fix the drive motor 41 to improve the stability of the drive motor 41 during operation, prevent displacement or damage caused by vibration, and thus extend the service life of the wireless charger. The charging interface 12 is used to connect to an external power source to provide power to the wireless charger.

[0099] In one embodiment, the wireless charger provided by the present invention further includes a battery cell, which is installed in the mounting cavity 11 and electrically connected to the electronic control component and the wireless charging coil 20.

[0100] In this embodiment, by adding a battery cell and electrically connecting it to the electronic control component and the wireless charging coil 20, the built-in power supply of the wireless charging device is realized. This allows the wireless charger to provide power for the operation of the drive component 40 and / or the operation of the wireless charging coil 20 without relying on an external power cord, significantly improving the portability and freedom of use of the product. Users can use its rotation and / or charging functions in scenarios without an external power source.

[0101] In one embodiment, the wireless charger provided by the present invention further includes a light-emitting element, which is disposed inside the wireless charging panel 32 and / or inside the housing 10. The wireless charging panel 32 and / or the housing 10 are respectively provided with light-transmitting portions, and the light-emitting element is electrically connected to the electronic control component.

[0102] In this embodiment, by setting up a light-emitting element and a corresponding light-transmitting part, and connecting them with an electronic control component, a visual dynamic light effect function is added to the product. By controlling it with the electronic control component, a variety of lighting effects can be generated using the light-emitting element, such as rotating synchronous brightness changes, chasing light rings or dynamic light spots, etc., making the rotating wireless charger a desktop atmosphere device with aesthetic appeal and fun, significantly enhancing the product's entertainment attributes and emotional value.

[0103] In addition, the charging progress and status of electronic devices can be displayed by changes in the light signals of the light-emitting components, thereby improving the user experience.
