Technical Field
[0001] This utility model relates to the field of charging equipment technology, and in particular to a wireless charging device. Background Technology
[0002] With the widespread adoption of electronic devices, wireless charging technology has been widely used due to its convenience. Traditional wireless charging devices typically only offer charging functionality, lacking intuitive status indicators or ambient lighting effects, resulting in a limited user experience and making it difficult for users to quickly determine the charging or device's operational status. Some existing technologies attempt to provide status indications using indicator lights, but these designs often suffer from uneven light distribution, monotonous visual effects, or complex structures, impacting both user experience and device aesthetics. Furthermore, the integration of light-emitting elements and light-guiding structures in existing wireless charging devices is usually quite simple, leading to low light utilization or light leakage. Simultaneously, the fixing and heat dissipation design of the wireless charging components directly affects the device's stability and lifespan. Utility Model Content
[0003] Therefore, it is necessary to provide a wireless charging device with an integrated top panel design, which is divided into a light-transmitting area and a magnetic area. The light-transmitting area is used for light to shine through, and the magnetic area is used for attracting objects. This effectively hides the light-emitting components and magnetic components, eliminating the need for additional light-transmitting components, as the light-transmitting area on the top panel acts as the light-transmitting component. When the device is working, the light shines directly through the light-transmitting area on the top panel. When the device is not working, the light-emitting components such as the light guide are hidden, making the wireless charging device more compact and simple.

The light-transmitting area is used for light to pass through, and the magnetic area is used for adsorbing the object to be adsorbed. This can effectively hide the light-emitting component and the magnetic component. There is no need to set up an additional light-transmitting component, as the light-transmitting area of the top plate acts as the light-transmitting component. When the device is working, the light shines directly through the light-transmitting area of the top plate. When the device is not working, the light-emitting components such as the light guide are hidden, which makes the wireless charging device more compact and simple.

[0014] In one embodiment, the light guide has a groove on the side facing the top plate, and foam is provided in the groove, which is bonded between the light guide and the top plate.
[0015] In one embodiment, the light guide includes a fixing part and a light-incident part. The fixing part has the groove, and the light-incident part is connected to the side of the fixing part near the wireless charging component.

[0027] With the widespread adoption of electronic devices, wireless charging technology has been widely used due to its convenience. Traditional wireless charging devices typically only offer charging functionality, lacking intuitive status indicators or ambient lighting effects, resulting in a limited user experience and making it difficult for users to quickly determine the charging or device operating status. Some existing technologies attempt to provide status indications using indicator lights, but these designs often suffer from uneven light distribution, monotonous visual effects, or complex structures, impacting user experience and device aesthetics. For example, insufficient light guide uniformity makes it difficult for light to diffuse evenly from the light-emitting element, leading to uneven lighting effects and affecting visual appeal; poor structural stability, with the wireless charging components and light guides not being securely fixed, makes them prone to displacement due to external forces or prolonged use, affecting charging efficiency or lighting effects; high assembly complexity, with unreasonable design of the fit between the light guide and the light-emitting element, increasing assembly difficulty and production costs; and a simplistic design of the light-transmitting area, with its shape and position lacking optimization, potentially affecting the overall aesthetics or lighting performance of the device. Furthermore, in existing wireless charging devices, the combination of the light-emitting element and the light guide structure is usually quite simple, resulting in low light utilization or light leakage. Meanwhile, the design of the wireless charging components' mounting and heat dissipation directly affects the device's stability and lifespan. Therefore, there is an urgent need for a wireless charging device with a reasonable structure, uniform light efficiency, and a combination of functionality and aesthetics to solve the aforementioned technical problems.
[0028] refer to Figures 1-3To address the aforementioned issues, this application provides a wireless charging device 10, comprising a bottom shell 20, a top plate 30, a magnetic absorbing element 70, a wireless charging assembly 40, a light-emitting element 50, and a light guide element 60. A receiving cavity 21 is formed in the bottom shell 20. The top plate 30 is disposed on the bottom shell 20 and covers the receiving cavity 21. The top plate 30 has a light-transmitting area 31 and a magnetic absorbing area 32. The wireless charging assembly 40, the magnetic absorbing element 70, the light-emitting element 50, and the light guide element 60 are all disposed in the receiving cavity 21. The wireless charging assembly 40 is located below the top plate 30, the magnetic absorbing element 70 is located below the magnetic absorbing area 32, and the light guide element 60 is located around the wireless charging assembly 40 and the magnetic absorbing element 70 and below the light-transmitting area. The light-emitting side of the light-emitting element 50 faces the light guide element 60.
[0029] See Figures 1-3The wireless charging device 10 includes a bottom shell 20, a top plate 30, a magnetic absorbing element 70, a wireless charging component 40, a light-emitting element 50, and a light guide element 60. The bottom shell 20 serves as the supporting structure for the wireless charging device 10, and a cavity 21 is formed within it. The cavity 21 can be used to install core components such as the wireless charging component 40, the light-emitting element 50, and the light guide element 60. The bottom shell 20 can be made of a high-strength material to improve the stability and durability of the wireless charging device 10. The top plate 30 is located on the bottom shell 20 and covers the cavity 21. The top plate 30 and the bottom shell 20 together form the outer shell of the device. The cooperation between the top plate 30 and the bottom shell 20 can protect the wireless charging device 10. Furthermore, the shapes of the top plate 30 and the bottom shell 20 can be customized as needed to improve the aesthetics of the wireless charging device 10. The top plate 30 has a light-transmitting area 31 and a magnetic area 32. The transparent area 31 of the top plate 30 allows light to pass through, while the magnetic area 32 attracts objects. Users can not only intuitively understand the charging status of the electronic device but also clearly see the position of the magnetic area 32, improving the user experience. The integrated design of the top plate 30 effectively hides the light-emitting component 50, the light guide component 60, and the magnetic component 70. It eliminates the need for additional light-transmitting components, as the light-transmitting area 31 of the top plate 30 acts as the light-transmitting component. When the device is working, light shines directly from the light-transmitting area 31 of the top plate. When the device is not working, the light-emitting components such as the light guide component 60 are hidden, making the wireless charging device more compact and simple. In some embodiments, the magnetic area 32 is a non-transmitting area, which helps to distinguish it from the light-transmitting area 31 on the top plate, making it easier for users to identify the two areas. The non-transparent areas have virtually no light transmission, ensuring the overall appearance of the device and avoiding stray light interference. The light transmittance of the non-transparent areas is less than 10%, even less than 1%. Light can pass through the area below the translucent area 31, enhancing the visual effect. The magnetic component 70 is located below the magnetic area 32. Specifically, within the magnetic area 32, the object to be attracted can be attracted. It should be noted that the top plate 30 of the magnetic area 32 does not have a magnetic function; instead, the magnetic component 70 is placed below the magnetic area 32, and the magnetic component 70 attracts the object through the magnetic area 32 of the top plate 30. The integrated design of the translucent area 31 and the magnetic area 32 of the wireless charging device 10 better conceals the light compared to a separate structure. That is, the light is visible when the device is in operation, but the user does not notice the presence of the light or the light guide component 60 when the device is not in operation, thus better ensuring the overall appearance of the wireless charging device 10.
[0030] In some embodiments, the light transmittance of the light-transmitting area 31 is between 10% and 50%. Setting the light transmittance of the light-transmitting area 31 to between 10% and 50% allows the light emitted by the light-emitting element to be diffused through the light-transmitting area 31 in a softer light, avoiding glare and improving the user experience. Specifically, the light-transmitting area 31 is located outside the projection area of the wireless charging assembly 40 on the top plate 30. When the wireless charging device 10 is charging, light can be seen in the light-transmitting area 31; when the wireless charging device 10 is not working, light cannot be seen in the light-transmitting area 31. Specifically, the wireless charging assembly 40 is located below the top plate 30. The wireless charging assembly 40 can use electromagnetic induction technology to efficiently transmit electrical energy to the receiving device. It should be noted that the light-transmitting area 31 is either a fully light-transmitting area or a semi-light-transmitting area, depending on its light transmission capability, to meet the visual and functional needs of different scenarios. Specifically, when light passes through the fully light-transmitting area, it can pass through clearly, suitable for high-brightness indicators or strong light environments, with a bright and transparent visual effect; when light passes through the semi-light-transmitting area, the light diffuses softly, suitable for ambient lighting or low-light environments, avoiding glare while maintaining uniform light emission. The light-emitting element 50 of the wireless charging device 10 can emit light. The light-emitting element 50 is used to provide charging status indication. Both the light-emitting element 50 and the light guide element 60 are located in the receiving cavity 21. Placing the light-emitting element 50 inside the receiving cavity 21 prevents it from being exposed outside the housing of the wireless charging device 10, which is beneficial for the maintenance of the light-emitting element 50, avoids wear and moisture damage to the light-emitting element 50, and helps to improve the service life of the wireless charging device 10. In some embodiments, the light-emitting element 50 can be an LED (light-emitting diode) lamp, etc., and the light guide 60 is located around the wireless charging assembly 40 and faces the light-transmitting area 31 of the top plate 30. The light guide 60 can evenly diffuse the light from the light-emitting element 50, effectively avoiding glare or light leakage. At the same time, the ambient light effect provided by the light-emitting element 50 can enhance the light efficiency and improve the aesthetics of the wireless charging device 10.
[0031] When a user uses the wireless charging device 10, the wireless charging component 40 starts working and transmits power when the device is powered on and a wirelessly charging-enabled electronic device is placed on it. In some embodiments, the light-emitting element 50 displays two states: emitting light and not emitting light, depending on whether it is charging or not. In other embodiments, the light-emitting element 50 can emit different colors of light depending on the charging status of the electronic device being charged, such as standby, charging, or fully charged. The light emitted by the light-emitting element 50 is uniformly scattered by the light guide 60 and then shines through the light-transmitting area 31 of the top plate 30, allowing the user to intuitively understand the current charging status of the electronic device, thus improving the user experience of using the wireless charging device 10.
[0032] In some embodiments, the light guide 60 has a ring-shaped structure, and the light-transmitting area 31 is also ring-shaped, with the light guide 60 directly facing the light-transmitting area 31. The ring-shaped light guide 60 and the ring-shaped light-transmitting area 31 work together to create a ring-shaped light strip on the top plate 30. The light guide 60 surrounds the wireless charging assembly 40, ensuring that the light from the light-emitting element 50 is emitted uniformly 360 degrees, allowing the light to diffuse evenly along the circular axis and avoiding uneven brightness in certain areas. Simultaneously, the precise alignment of the light guide 60 with the light-transmitting area 31 ensures soft light transmission, preventing glare or light leakage and improving user visual comfort. In terms of appearance, the ring-shaped light effect enhances the aesthetics of the wireless charging device 10, giving it a technological feel and also serving as an ambient light.
[0033] In some embodiments, the bottom shell 20 has a support frame 22 within the receiving cavity 21. The support frame 22 provides a stable mounting platform within the receiving cavity 21 of the bottom shell 20. The support frame 22 can be integrally formed with the bottom shell 20, facilitating the assembly of the wireless charging device 10. The light guide 60 and the wireless charging assembly 40 are mounted on the support frame 22, ensuring their stable positions. Simultaneously, the support frame 22 forms a physical isolation layer, preventing direct contact between the wireless charging assembly 40 and the light guide 60 and the bottom shell 20. The top plate 30 and the support frame 22 together form a space for placing precision components, which helps protect the internal precision components. In some embodiments, the light guide 60 and the wireless charging assembly 40 are spaced apart, and the wireless charging assembly 40 is spaced apart from other structures, allowing sufficient space for heat dissipation. In some embodiments, the support frame 22 has multiple positioning points to ensure accurate installation of each component.
[0034] In some embodiments, the support frame 22 is provided with an assembly groove 221, and the bottom of the light guide 60 is disposed within the assembly groove 221, with the bottom of the light guide 60 abutting against the bottom of the assembly groove 221 to ensure that the light guide 60 will not loosen or fall off during long-term use. In some embodiments, the structure of the assembly groove 221 is optimized according to the outer peripheral shape of the light guide 60 to simultaneously support the sides and bottom of the light guide 60, which is beneficial to improving the overall structural strength. In some embodiments, the interior of the assembly groove 221 can be made of a slightly elastic material, which can reduce the impact of external impacts on the light guide 60. Even if the wireless charging device 10 is slightly bumped, the light guide 60 can still remain stable, avoiding light path deviation due to vibration. In some embodiments, silicone gaskets can be provided in the assembly groove 221 and the light guide 60, and the silicone gaskets have a cushioning effect.
[0035] The support frame 22 has a light-transmitting opening 222, which forms a light transmission channel. A light guide 60 covers one end of the light-transmitting opening 222. Light emitted by the light-emitting element 50 passes through the light-transmitting opening 222 and further through the light guide 60. In some embodiments, a heat dissipation channel can be provided around the light-transmitting opening 222, allowing the heat generated by the light-emitting element 50 during operation to be dissipated naturally through the light-transmitting opening 222. The light-emitting element 50 is located on the side of the support frame 22 away from the top plate 30, with a portion of the light-emitting element 50 extending into the other end of the light-transmitting opening 222. The light guide 60, the light-transmitting port 222 on the support frame 22, and the light-emitting component 50 form a layered light path transmission structure. By opening the light-transmitting port 222 on the support frame 22, it can be ensured that there will be no light leakage or glare during the light process. At the same time, in terms of structure, the components are spaced apart and have a certain heat dissipation space. This not only enables the normal light indication of the wireless charging device 10, but also makes the internal structure of the wireless charging device 10 compact and stable, which is convenient for the assembly of the wireless charging device 10.
[0036] See Figure 3 The wireless charging component 40 is clamped and fixed between the support frame 22 and the top plate 30. The space between the support frame 22 and the top plate 30 provides a safe and stable installation environment for the wireless charging component 40, ensuring accurate positioning of the charging module while effectively avoiding stress concentration problems that may occur with traditional fixing methods. The wireless charging component 40 can realize wireless energy transmission. Based on the principle of electromagnetic induction, the wireless charging component 40 can transmit electrical energy to wireless charging-enabled electronic devices, such as smartphones and wireless headphones, in a contactless manner. In some embodiments, the wireless charging component 40 includes a transmitting coil, a magnetic shielding layer, a control circuit board, and a heat dissipation structure. The transmitting coil can be precisely wound from high-purity copper wire and is responsible for generating an alternating electromagnetic field. The energy transmission efficiency can be improved and heat generation reduced by optimizing the coil layout. The magnetic shielding layer can be made of ferrite or other high-permeability materials to prevent electromagnetic interference and enhance magnetic field directionality, effectively avoiding energy loss and protecting surrounding electronic components from interference. The control circuit board can employ an intelligent power management chip to dynamically adjust the output power and support multiple wireless charging protocols, enabling the wireless charging device 10 to be compatible with devices from different brands and expanding its application scenarios. The heat dissipation structure can incorporate thermally conductive silicone or graphene heat sinks to ensure long-term operational stability. In some embodiments, the wireless charging device 10 may include a temperature sensor to monitor and adjust the charging power of the wireless charging component 40 in real time.
[0037] To improve the stability of the internal structure of the wireless charging device 10, the wireless charging device 10 also includes foam 611. Specifically, a groove 61 is formed on the side of the light guide 60 facing the top plate 30, and foam 611 is placed in the groove 61. The foam 611 can be made of elastic polyurethane foam 611 material, which has moisture-proof and dust-proof properties. The foam 611 is bonded between the light guide 60 and the top plate 30. In one embodiment, the bottom of the foam 611 is bonded to the light guide 60 with adhesive, and the top of the foam 611 naturally and elastically presses against the inner surface of the top plate 30. The foam 611 can effectively absorb external impacts and vibrations, prevent the light guide 60 from making hard contact with the top plate 30, and at the same time, eliminate the assembly gap between the light guide 60 and the top plate 30, prevent light leakage and uneven light spots, and improve the visual effect of the annular light strip.
[0038] In some embodiments, the light guide 60 includes a fixing part 62 and a light-incident part 63. The fixing part 62 has a groove 61, which can wrap the foam 611 to stabilize the position of the foam 611. The light-incident part 63 is connected to the side of the fixing part 62 near the wireless charging assembly 40. The light-emitting side of the light-emitting element 50 faces the light-incident part 63 so that the light emitted by the light-emitting element 50 is displayed through the light-incident part 63. In some embodiments, the groove wall of the groove 61 extends towards the top plate 30 and is directly opposite the light-transmitting area 31 in the extending direction. This allows the light generated by the light-emitting element 50 to be efficiently guided to the preset light-transmitting area, eliminating stray light interference and improving the light efficiency quality of the wireless charging device 10.
[0039] In some embodiments, the top plate 30 includes a light-transmitting plate and a faceplate. The light-transmitting plate has high light transmittance and can be thinner to maximize charging efficiency. The faceplate can be patterned using a screen printing process to improve the aesthetics of the wireless charging device 10. The surface of the faceplate can be treated to be scratch-resistant and wear-resistant. The faceplate is attached to the side of the light-transmitting plate opposite to the wireless charging assembly 40, and a light-shielding area and a light-transmitting area 31 are formed on the faceplate. The light-transmitting plate and the faceplate not only protect the internal precision components but also ensure the light efficiency of the wireless charging device 10.
[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
