Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a wireless charging device for automobiles. Background Technology

[0002] Currently, most cars on the market are equipped with interior ambient lighting, mainly for decoration and illumination, to enhance the aesthetics of the car interior and the driving experience. However, traditional automotive ambient lighting or other products are usually powered by wired connections, that is, directly connected to the vehicle's power system through wiring harnesses. While this design can provide a stable power supply, it increases the complexity of wiring inside the vehicle. Utility Model Content

[0003] Therefore, it is necessary to provide a wireless charging device for automobiles to address the problem that the use of wired connections for power supply of traditional automotive ambient lighting or other products increases the complexity of wiring inside the vehicle.

[0004] A wireless charging device for automobiles includes: a support assembly; a first wireless charging module disposed on an automobile; a wireless charging receiver assembly disposed on the support assembly; a light-emitting assembly disposed on the support assembly, the light-emitting assembly being electrically connected to the wireless charging receiver assembly, wherein the circuit between the wireless charging receiver assembly and the light-emitting assembly is configured to be connected when the distance between the wireless charging receiver assembly and the first wireless charging module is less than L and disconnected when the distance between the wireless charging receiver assembly and the first wireless charging module is greater than L; and / or, a second wireless charging module electrically connected to the wireless charging receiver assembly, wherein the circuit between the wireless charging receiver assembly and the second wireless charging module is configured to be connected when the distance between the wireless charging receiver assembly and the first wireless charging module is less than L and disconnected when the distance between the wireless charging receiver assembly and the first wireless charging module is greater than L.

[0005] This application discloses a wireless charging device for automobiles. When the wireless charging receiver is in contact with or at a distance less than L from the first wireless charging module, it generates electrical energy. For example, the wireless charging receiver is placed on the first wireless charging module, similar to the wireless charging function of a mobile phone, enabling stable charging. This design eliminates the need for traditional wiring harnesses, reducing the complexity of wiring within the vehicle, improving installation convenience, and maintaining a clean and aesthetically pleasing interior. It also allows for free adjustment of the ambient light position, allowing users to adjust the light position according to their needs without being restricted by fixed cables. Furthermore, it avoids cable wear or poor contact problems that may occur with traditional wired connections, reducing maintenance requirements and extending service life. This method also allows for free control of the on / off state of the light-emitting components, with a fast response speed, ensuring power supply stability while avoiding energy waste. The color of the light-emitting components in this design is not specified; it can be a single color or a combination of multiple colors. In another embodiment, a second wireless charging module can be electrically connected to the wireless charging receiver. The second wireless charging module acts as a converter, providing power to other products such as mobile phones and watches. This application's wireless charging device for automobiles optimizes the power supply method while maintaining the ambient light function, improving user experience and product practicality.

[0006] In one embodiment, the first wireless charging module includes at least a power supply coil, and the wireless charging receiving component includes a receiving coil and a wire. The receiving coil is disposed on the support component, and the wire is connected to both the receiving coil and the light-emitting component. When the power supply coil and the receiving coil are in close contact or at close range, they form a highly efficient coupling. The power supply coil generates a magnetic signal through an alternating magnetic field, and the receiving coil converts the magnetic signal into an electrical signal based on the principle of electromagnetic induction, thereby achieving a stable power supply to the light-emitting component. This design replaces the traditional wiring harness power supply method, effectively reducing the complexity of wiring inside the vehicle and significantly improving installation convenience. Simultaneously, the electromagnetic coupling-based power supply method avoids wear and tear caused by physical contact, improving the system's reliability and service life.

[0007] In one embodiment, the wireless charging receiver is located on the outer side of the support component or inside the support component. The wireless charging receiver can be located either on the outer side or inside the support component; its position is not fixed and can be set according to requirements. For example, placing it inside the support component can better protect the wireless charging receiver, preventing it from malfunctioning due to external factors and affecting the product's lifespan, and also has a positive impact on the product's appearance quality. Whether external or internal, stable power supply can be achieved through electromagnetic induction, replacing traditional wiring harnesses and reducing wiring complexity.

[0008] In one embodiment, there are multiple wireless charging receiver components, all of which are mounted on the support component and electrically connected to the light-emitting component. By electrically connecting multiple wireless charging receiver components to the light-emitting component, they can operate simultaneously or alternately. Even if the power supply efficiency of a single wireless charging receiver component decreases due to positional misalignment, a stable power supply can still be maintained through the other wireless charging receiver components. This design reduces the requirement for precise alignment, allows the wireless charging receiver components to maintain effective coupling with the vehicle-mounted first wireless charging module over a wider range, and simplifies the debugging process.

[0009] In one embodiment, the support component is a silicone pad. By using a silicone pad as the support component, the properties of silicone allow the wireless charging receiver component to maintain a tight fit with the vehicle module, preventing the light-emitting component from shifting or loosening due to vibration, ensuring the stability of the light emission. When the silicone pad is placed in the wireless charging area, it can automatically couple and energize, causing the light-emitting component to emit light.

[0010] In one embodiment, the light-emitting component includes a light guide strip and a light-emitting element. The light guide strip is disposed on the support component, and the light-emitting element is electrically connected to the wireless charging receiver component. The light-emitting element is positioned opposite to the end of the light guide strip. By positioning the light-emitting element opposite to the end of the light guide strip, the light-emitting element is directly aligned with the end of the light guide strip, ensuring efficient light entry into the light guide strip, reducing light energy loss, and achieving a uniform and bright lighting effect. The light guide strip can be bent as needed. Compared to traditional light-emitting tubes, the light guide strip has the advantage of being able to bend to the shape of the support component, resulting in a more aesthetically pleasing appearance.

[0011] In one embodiment, the light-emitting element is an LED chip. By using LED chips as the light-emitting element, the LED chips possess high brightness and low energy consumption characteristics, providing ample and uniform light source for the light guide strip, ensuring clear and soft ambient lighting effects. Furthermore, the LED chips are small in size, facilitating precise alignment with the end of the light guide strip, saving installation space, and maintaining the overall slim and lightweight design of the ambient light.

[0012] In one embodiment, there are two light-emitting elements. One of the two light-emitting elements is positioned opposite one end of the light guide strip, and the other is positioned opposite the other end of the light guide strip. By having two light-emitting elements emit light simultaneously from both ends of the light guide strip, the light attenuation or uneven brightness caused by light entering from one side is effectively reduced, ensuring a uniform and consistent lighting effect throughout the entire light guide strip. This design increases the overall brightness of the light guide strip and reduces dark areas through light counteracting, achieving a softer and more natural visual effect. Even if a single light-emitting element fails, the light-emitting element at the other end can still maintain basic lighting function, improving the overall fault tolerance of the ambient light.

[0013] In one embodiment, there are multiple wireless charging receiver components, all of which are mounted on the support component. There are also multiple light-emitting elements, the number of which is the same as the number of wireless charging receiver components, and each light-emitting element is electrically connected to a corresponding wireless charging receiver component. Each light-emitting element is positioned opposite the end of at least one light guide strip. Each light-emitting element is powered by an independent wireless charging receiver component, forming a modular power supply unit. This prevents a single power supply failure from causing overall lighting failure, improving system reliability. Multiple wireless charging receiver components can be distributed across different positions on the support component, allowing for flexible configuration of light sources according to the distribution requirements of the light guide strips. This enables multiple light guide strips to produce overlapping ambient lighting effects, enhancing the user experience. Furthermore, if a single wireless charging receiver component or light-emitting element fails, only the corresponding component needs to be replaced, without affecting the operation of other components, reducing maintenance difficulty and cost.

[0014] In one embodiment, the light guide strip is located on one side of the support component, or on two adjacent sides of the support component, or on three adjacent sides of the support component, or the light guide strip surrounds the support component. The light guide strip on the support component can be configured in a single-sided, multi-sided, or wraparound layout according to the installation requirements of different areas within the vehicle, adapting to diverse lighting effects and functional requirements. Furthermore, multi-sided or wraparound light guides can create a three-dimensional or continuous lighting atmosphere, enhancing the overall integrity and premium feel of the vehicle interior environment. This design ensures lighting functionality while also considering spatial adaptability and visual appeal.

[0015] In one embodiment, the light guide extends to external components. By extending the light guide to other parts of the vehicle, light can be conducted to other areas inside the vehicle, achieving wider ambient lighting and enhancing the overall visual effect. This design allows the light guide to be flexibly placed in different locations inside the vehicle, such as connecting doors, the center console, or seat areas, achieving more flexible and effective lighting solutions. Furthermore, it can be powered by the wireless charging receiver via electromagnetic induction, avoiding traditional wiring and reducing wiring complexity and cost.

[0016] In one embodiment, the light guide strip has a circular or square cross-section. The circular, square, or other shapes of the light guide strip enable stable light transmission. The specific design only needs to achieve the desired light-emitting effect; the shape is not critical.

[0017] In one embodiment, a charging device is also included. This charging device is electrically connected to the wireless charging receiver and has a charging port. The charging device can be used to power external electrical appliances. By electrically connecting the charging device to the wireless charging receiver, the ambient light can be wirelessly powered while simultaneously powering external electrical appliances through the charging port, enhancing the product's versatility and achieving multi-functional integration. This design allows users to directly charge the product without needing to carry an additional charger, expanding the power supply function and improving ease of use, thus enhancing the user experience.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

The wireless charging receiver 3 generates electrical energy when it is in contact with or less than a distance L from the first wireless charging module. For example, the wireless charging receiver 3 is placed on the first wireless charging module, similar to the wireless charging function of a mobile phone, enabling stable charging. This design eliminates the need for traditional wiring harnesses, reducing the complexity of wiring within the vehicle, improving installation convenience, and maintaining a clean and aesthetically pleasing interior.

The color of the light-emitting component 2 in this design is not specified; it can be a single color or a combination of multiple colors. In another embodiment, a second wireless charging module can be electrically connected to the wireless charging receiver 3. The second wireless charging module acts as a converter, providing power to other products such as mobile phones and watches. This application's wireless charging device for automobiles optimizes the power supply method while ensuring the ambient light function, improving user experience and product practicality.

[0036] like Figure 3 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first wireless charging module includes at least a power supply coil, and the wireless charging receiving component 3 includes a receiving coil 31 and a wire 32. The receiving coil 31 is disposed on the support component 1, and the wire 32 is connected to the receiving coil 31 and the light-emitting component 2 respectively. When the power supply coil and the receiving coil 31 are in close contact or at close range, they form a highly efficient coupling. The power supply coil generates a magnetic signal through an alternating magnetic field, and the receiving coil 31 converts the magnetic signal into an electrical signal based on the principle of electromagnetic induction, thereby achieving a stable power supply to the light-emitting component 2. This design replaces the traditional wiring harness power supply method, effectively reducing the complexity of wiring inside the vehicle and significantly improving installation convenience. At the same time, the electromagnetic coupling-based power supply method avoids the wear and tear problems caused by physical contact, improving the reliability and service life of the system.

[0037] In addition to the features of the above embodiments, this embodiment further specifies that the wireless charging receiver 3 is located on the outer side of the support component 1 or on the inner side of the support component 1. The wireless charging receiver 3 can be located either on the outer side or inside the support component 1; its position is not fixed and can be set according to requirements. For example, placing it inside the support component 1 can better protect the wireless charging receiver 3, preventing it from malfunctioning due to external factors and affecting the product's lifespan, and also has a positive impact on the product's appearance quality. Whether external or internal, stable power supply can be achieved through electromagnetic induction, replacing traditional wiring harnesses and reducing wiring complexity.

[0038] like Figure 1 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of wireless charging receiver components 3 is multiple, all of which are disposed on the support component 1, and all of which are electrically connected to the light-emitting component 2. By electrically connecting multiple wireless charging receiver components 3 to the light-emitting component 2, the multiple wireless charging receiver components 3 can work simultaneously or alternately. Even if the power supply efficiency of a single wireless charging receiver component 3 decreases due to positional misalignment, a stable power supply can still be maintained through the other wireless charging receiver components 3. This design reduces the requirement for precise alignment, allows the wireless charging receiver components 3 to maintain effective coupling with the vehicle-mounted first wireless charging module over a wider range, and simplifies the debugging process.

[0039] In addition to the features of the above embodiments, this embodiment further specifies that the support component 1 is a silicone pad. By using a silicone pad as the support component 1, the properties of silicone allow the wireless charging receiver component 3 to maintain a tight fit with the vehicle module, preventing the light-emitting component 2 from shifting or loosening due to vibration, ensuring the stability of light emission. When the silicone pad is placed in the wireless charging area, it can automatically couple and energize, causing the light-emitting component 2 to emit light.

[0040] like Figure 1 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the light-emitting component 2 includes a light guide strip 21 and a light-emitting element 22. The light guide strip 21 is disposed on the support component 1, and the light-emitting element 22 is electrically connected to the wireless charging receiver component 3. The light-emitting element 22 is disposed opposite to the end of the light guide strip 21. By distributing the light-emitting element 22 opposite to the end of the light guide strip 21, the light-emitting element 22 is directly aligned with the end of the light guide strip 21, ensuring that light enters the interior of the light guide strip 21 efficiently, reducing light energy loss, and achieving a uniform and bright lighting effect. The light guide strip 21 can be bent as needed. Compared with traditional light-emitting tubes, the light guide strip 21 has the advantage of being able to bend into a corresponding shape to adapt to the shape of the support component 1, making the appearance more aesthetically pleasing.

[0041] In addition to the features of the above embodiments, this embodiment further specifies that the light-emitting element 22 is an LED chip. By using an LED chip as the light-emitting element 22, the LED chip has high brightness and low energy consumption characteristics, providing sufficient and uniform light source for the light guide strip 21, ensuring clear and soft ambient lighting effects. Moreover, the LED chip is small in size, facilitating precise alignment with the end of the light guide strip 21, saving installation space, and maintaining the overall slim design of the ambient light.

[0042] In addition to the features of the above embodiments, this embodiment further specifies that: the number of light-emitting elements 22 is two, one of the two light-emitting elements 22 is disposed opposite to one end of the light guide strip 21, and the other of the two light-emitting elements 22 is disposed opposite to the other end of the light guide strip 21. By having the two light-emitting elements 22 emit light from both ends of the light guide strip 21 simultaneously, the problem of light attenuation or uneven brightness caused by light entering from one side is effectively reduced, ensuring that the lighting effect of the entire light guide strip 21 is uniform and consistent.

Moreover, it can also be powered by the wireless charging receiver 3 through electromagnetic induction, avoiding traditional wiring and reducing the complexity and cost of wiring.

[0046] In addition to the features of the above embodiments, this embodiment further specifies that the cross-section of the light guide strip 21 is circular or square. The circular, square, or other shapes of the light guide strip 21 enable stable light transmission. The specific design only needs to achieve the light-emitting effect; the shape is not critical.

[0047] In addition to the features of the above embodiments, this embodiment further specifies that it includes a charging device electrically connected to the wireless charging receiver 3.
