The wireless charging component and the circuit board are installed inside the housing. Several light-emitting elements are provided on the side of the light-transmitting column. The light-emitting elements are located inside the housing. One end of the light-transmitting column extends through the housing to the outside of the housing. The light emitted by the light-emitting elements is emitted to the outside of the housing through the light-transmitting column.

[0007] The present invention provides a wireless charger in which the light-transmitting column is cylindrical.

[0016] The beneficial effects of this utility model are:

[0017] This utility model proposes a wireless charger that combines a light-transmitting column with internal lighting components inside the casing of a traditional wireless charger to achieve a cool ambient lighting experience.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1-6As shown, this embodiment provides a wireless charger, including a housing 1, a wireless charging component 2, a circuit board 3, and a light-transmitting column 4. The wireless charging component 2 and the circuit board 3 are installed inside the housing 1. Several light-emitting elements 5 are provided on the side of the light-transmitting column 4, located inside the housing 1. One end of the light-transmitting column 4 extends through the housing 1 to the outside, and the light emitted by the light-emitting elements 5 is emitted to the outside of the housing 1 through the light-transmitting column 4. The wireless charging component 2 includes a wireless transmitting coil 21 and a magnet 22, with the wireless transmitting coil 21 electrically connected to the circuit board. The housing 1 has an electrical connection part 7 for connecting to an external power source, and the other end of the electrical connection part 7 is electrically connected to the circuit board 3. A portion of the electrical connection part 7 is shown in the accompanying drawings. The technical solution of this embodiment achieves a cool ambient lighting experience by introducing a combination of a light-transmitting column and internal lighting components inside the traditional wireless charger casing: First, the casing, as a supporting structure, not only holds the charging components and circuit board, but also provides a hole for the light-transmitting column to pass through, and uses a snap-fit ​​structure at the exit point to ensure dust and splash protection; the wireless charging components include a wireless transmitting coil 21 and a magnetic ring 22, which are arranged at a safe distance from the light-transmitting column; the circuit board integrates a conventional charging management module, MCU (microcontroller unit), and lighting driver module, and can be used with a communication interface (such as Bluetooth or Wi-Fi). External control is achieved; the light-transmitting column is made of optical-grade transparent material (such as PMMA or PC) to optimize light diffusion; several LED light components are installed inside the housing near the side of the light-transmitting column to efficiently guide the light source into the column; the MCU drives the LEDs to emit corresponding colors, brightness, and breathing / flickering light effects according to the wireless charging status (standby, charging, fully charged, abnormal) or external commands, so that the light is evenly diffused to the outside of the housing through the light-transmitting column. This can not only gently indicate the charging status in low-light environments at night, but also create a cyberpunk or brand-themed atmosphere through multi-color dynamic effects. The product solution in this embodiment is comprehensively optimized in terms of structure, optics, and circuit layout, which can significantly improve the user's immersive interactive experience in multiple scenarios.

[0030] Preferably, the light-transmitting column 4 is cylindrical. Designing the light-transmitting column as cylindrical achieves an optimal balance in terms of optical effect, manufacturing process, and structural strength. The cylindrical light-transmitting column has a symmetrical geometric structure, enabling the light emitted by the internal lighting components to be evenly distributed radially. Through the refraction and diffusion structure within the material, the light is evenly projected onto the exterior of the housing, avoiding light spots or dark areas that may occur with asymmetrical shapes. The cylindrical structure also facilitates one-time molding through injection molding or extrusion processes, reducing processing complexity and production costs. Simultaneously, the cylindrical cross-section has good strength and resistance to deformation under stress, maintaining shape stability during housing assembly and use. When co-layout with the wireless charging components and circuit board, the cylindrical cross-section allows for reserved space and ensures a safe distance from the coil. Furthermore, it facilitates the addition of micro-textures, facets, or sandblasting treatments inside or on the surface of the light-transmitting column to further optimize the optical diffusion effect.

[0031] Preferably, the light-transmitting column 4 has grooves 41 at both ends. These grooves can form stepped or annular grooves at both ends of the light-transmitting column. This can be achieved during manufacturing through a mold in the injection molding stage or in subsequent machining, giving the exposed ends a differentiated optical edge effect: when LED light enters the light-transmitting column, the end grooves can guide some of the light to diffuse laterally or obliquely, enhancing the three-dimensionality of the ambient lighting. Simultaneously, it provides more light path variations on top of the diffused side light, making the nighttime effect more layered. Furthermore, a product logo is provided at the bottom of the groove 41, with the logo in a recessed structure. This design highlights brand recognition while also considering aesthetics and functional details. Recessed signage is created by carving or injection molding the signage content (such as a brand logo or model information) into a groove or recessed mold at the bottom of the light-transmitting column. During manufacturing, a corresponding recessed mold can be set in the injection mold or laser etching can be performed later. Micro-texturing ensures that the signage is clear and contrasts with the surrounding optical structure. Because the signage is in a recessed area, it avoids strong direct light spots during light transmission. At the same time, when the internal LED light passes through the light-transmitting column, the recessed signage area can form a soft glow or shadow effect through micro-refraction or diffusion, enhancing the visual depth.

[0032] Preferably, the material of the light-transmitting column 4 is transparent PC. Transparent PC material has good light transmittance and impact strength, which can ensure the efficient transmission of LED light in the light-transmitting column, while it is not easy to break or deform due to external force or temperature changes. In the manufacturing process, PC material is suitable for injection molding and has good fluidity. The required geometric shape and surface texture of the light-transmitting column can be designed through mold. In order to enhance the diffusion effect, micro-textures or refractive surface structures can be introduced into the PC injection molded parts by introducing micro-textures or refractive surface structures on the mold surface or in the injection molding process, so that the light is refracted and diffused multiple times during transmission, thereby creating a soft and uniform external light effect.

[0033] Preferably, the lighting element 5 is an LED bead, which is electrically connected to and mounted on the circuit board 3. The LED beads can be directly soldered or inserted onto a dedicated PCB board or onboard bracket, enabling mass production through standard SMT or plug-in methods, improving assembly efficiency and consistency. The PCB layout reserves a position corresponding to the light-transmitting column, ensuring the LED light source is close to the side of the light-transmitting column. The designed PCB bracket and snap-fit ​​structure ensure good light coupling between the LED and the light-transmitting column, reducing light loss and improving luminous efficiency. The circuit board integrates an LED driver circuit, which uses a driver chip and MCU to control and achieve dynamic effects such as multi-color, pulse, and breathing effects. In the circuit design, the heat dissipation path can be optimized through multi-layer boards and copper foil layout, conducting LED heat to the outside through the circuit board, improving reliability and safety. Electrical connections can be made using spring contacts, sockets, or solder joints, ensuring reliable connections and easy maintenance.

[0034] Preferably, there are four light elements 5, which are symmetrically distributed around the light-transmitting column 4. The four LEDs are symmetrically arranged at 90-degree intervals on the side or bottom of the light-transmitting column, forming a symmetrical light source layout with the cylindrical light-transmitting column. This ensures that the light is injected into the light-transmitting column from multiple angles and is fully diffused, so that the final emitted light effect is uniform and without obvious dark areas or light spots. The symmetrical layout also helps to ensure consistent light effect under different installation directions (such as desktop, embedded or wall-mounted). In PCB design and mechanical structure, the four LED positions can be precisely positioned on the circuit board or bracket, and they can be fixed to the side of the light-transmitting column using slots or support structures. In drive control, the four LEDs can be driven by the same or grouped strategies to achieve interactive experiences such as unified or dynamic color changing and rotating light effects. In addition, the symmetrical distribution of the four LEDs makes the structure more balanced in terms of mechanical stress and heat distribution, which is convenient for heat dissipation design and avoids overheating on one side.

[0035] Preferably, the housing 1 is also equipped with a light switch 6, which is electrically connected to the circuit board 3. The light switch can be a physical button or a touch switch, installed in an easily accessible location on the housing, such as the side or top edge. It is connected to the MCU or dedicated control circuit on the circuit board via wiring or ribbon cables. Users can directly turn the ambient light mode on, off, or switch modes without an app or smart system, providing flexible manual control and a more user-friendly interaction method. In this embodiment, the light switch is a physical button, installed on the upper part of the housing.

[0036] Preferably, the housing 1 is formed by connecting a front housing 11 and a rear housing 12. One end of the light-transmitting column 4 passes through the front housing 11, and the rear housing 12 is made of a transparent material. The dual-housing structure makes production and assembly more flexible: the front housing can be made of metal or opaque plastic, and the rear housing can be made of a transparent material (such as PC or PMMA). Optically matching the material of the light-transmitting column, it can form a rear optical reflection or diffusion area. The remaining light emitted from the other end of the light-transmitting column is diffused again through the transparent rear housing or used as a decorative backlight, thereby creating a richer light and shadow layer in the overall effect. In terms of manufacturing process, the front and rear housings can be combined to form the housing by snap-fit, screw connection, or adhesive bonding.

[0037] Preferably, the light-transmitting column 4 passes through the middle of the wireless transmitting coil 21, the magnet ring 22, and the circuit board 3, with the other end of the light-transmitting column 4 extending to the inner side of the rear housing 12. After the light-transmitting column enters from the top of the housing, it passes through the space between the wireless charging component area and the circuit board along the center or a designated position inside. A safe passage needs to be reserved in the structural design to ensure that it does not interfere with the charging coil. In terms of implementation, a dedicated opening or groove can be designed between the wireless charging component and the circuit board to allow the light-transmitting column to pass through without affecting the working area of ​​the coil. After passing through the middle, the light-transmitting column extends backward to the inner side of the transparent rear housing, using the rear space to form a secondary diffusion area or a backlight decoration area. Through material matching, the LED light is transmitted along the light-transmitting column, and some of the light continues to propagate into the interior of the rear housing to form a soft backlight, enhancing the atmosphere. This layout makes full use of the internal space and avoids occupying additional external space of the housing. Moreover, by optimizing the position, the LED light injection point is close to the center of the charging area or a specific angle, realizing multi-path propagation of light.

[0038] It should be noted that the wireless charger in this embodiment is a relatively basic form and structure. Different types of wireless chargers can be formed by adding practical structures such as brackets according to actual usage needs, so that the effect of the light can be displayed more clearly.
