[0035] The present application provides a vehicle, which includes a storage box, a light source and the vehicle-mounted expansion dock of any embodiment of the present application. The light source is arranged in the storage box, and at least part of the shell of the vehicle-mounted expansion dock extends into the storage box. The side of the light-transmitting portion close to the first surface is opposite to the light source, and the light from the light source can pass through the first surface and the second surface through the light-transmitting portion.

[0036] A vehicle expansion dock is a device installed in a vehicle to expand the vehicle's interface functions. For example, it can add USB interfaces, power interfaces, HDMI interfaces, etc., making it easier for users to connect and use various electronic devices in the car, such as mobile phones, tablets, mobile hard drives, etc.

[0037] A storage box is a space inside a vehicle used to store items. It usually has a certain volume and shape and can hold miscellaneous items to make the vehicle interior more tidy. For example, a storage box can be a vehicle's armrest box.

[0038] The light source is a luminous component in the vehicle storage box, which provides lighting for the vehicle or serves other related functions such as indication.

[0039] Exemplarily, the light source is a light-emitting component in a vehicle storage box, which provides lighting inside the storage box to facilitate users to take items out of the storage box.

[0040] This application provides a vehicle-mounted expansion dock 10, see Figures 1 to 4 The vehicle docking station 10 includes a housing 1 and a light-transmitting portion 2. The housing 1 has a first surface 11 and a second surface 12 disposed opposite each other along a first direction. The light-transmitting portion 2 is disposed on the housing 1 and extends from the first surface 11 to the second surface 12. Light can pass through the light-transmitting portion 2 through the first surface 11 and the second surface 12.

[0041] The housing 1 is the external structure of the vehicle docking station 10, protecting the internal circuit components, securing the interface positions, and providing physical support. It also provides support for the installation and fixation of the vehicle docking station 10. The shape and structure of the housing 1 are not limited here and are determined according to actual design requirements.

[0042] In some embodiments, the storage box is provided with a dedicated slot or track for securing the housing 1 of the vehicle docking station 10 so that the vehicle docking station 10 does not wobble while the vehicle is in motion. For example, the slot or track can be made of soft rubber, which not only provides a secure fit but also prevents scratches on the housing 1 of the vehicle docking station 10.

[0043] The light-transmitting portion 2 is a structure on the housing 1 of the vehicle-mounted expansion dock 10 . The light-transmitting portion 2 is configured to allow light to pass through the housing 1 to achieve functions such as lighting or indication.

[0044] The specific structure of the light-transmitting portion 2 is not limited here. For example, the light-transmitting portion 2 can be a through area opened on the shell 1 of the vehicle docking station 10, and there is no obstruction of the shell 1 within the light-transmitting portion 2, and light can pass through the light-transmitting portion 2 and pass through the first surface 11 and the second surface 12.

[0045] The specific location of the light-transmitting portion 2 is not limited here and is determined according to the light irradiation location. For example, the light-transmitting portion 2 is arranged opposite to the light source, and the light emitted by the light source can directly pass through the light-transmitting portion 2 and pass through the first surface 11 and the second surface 12.

[0046] The first surface 11 and the second surface 12 are two surfaces on the housing 1 that are opposite to each other along a first direction. The first direction is for the convenience of explanation. Figure 1 and Figure 3 For example, the first direction may be the thickness direction of the housing 1 , and the first surfaces may be two surfaces of the housing 1 that are opposite to each other along the thickness direction.

[0047] In some embodiments, a sealing structure may be designed at the contact portion between the storage box and the housing 1 of the vehicle docking station 10 to prevent dust, liquid, etc. from entering the interior of the vehicle docking station 10 , thereby improving the safety and reliability of the vehicle docking station 10 .

[0048] When the vehicle expansion dock 10 is set on the storage box of the vehicle, in order to prevent the vehicle expansion dock 10 from taking up too much storage space of the storage box, the surface of the shell 1 of the vehicle expansion dock 10 is generally nested with the storage cavity of the storage box as much as possible. For a storage box with a light source provided on the mating surface, after the vehicle expansion dock 10 is mated, the shell 1 is likely to block the light source, affecting the lighting function of the light source.

[0049] The vehicle docking station 10 provided in the embodiment of the present application has a light-transmitting portion 2 extending from the first surface 11 to the second surface 12 of the housing 1. The light-transmitting portion 2 creates a channel for light to propagate, allowing light to pass through the first surface 11 and the second surface 12. This prevents light from being completely blocked by the housing 1 and allows it to pass through the light-transmitting portion 2.

[0050] In some embodiments, see Figures 1 to 4 The housing 1 is provided with a mounting through hole 13 , which extends along the first direction and passes through the first surface 11 and the second surface 12 , and the light-transmitting portion 2 is provided in the mounting through hole 13 .

[0051] The mounting hole 13 is a hole formed in the housing 1 and extends along a first direction and passes through the first and second surfaces 11 and 12 of the housing 1 for mounting the light-transmitting portion 2. The specific structure and location of the mounting hole 13 are determined by the structure and location of the light-transmitting portion 2.

[0052] In some embodiments, the light-transmitting portion 2 can be designed with a protrusion or groove structure at the point where it contacts the mounting hole 13. This structure mates with a corresponding structure on the inner wall of the mounting hole 13 to achieve a more secure installation. For example, an annular groove can be provided on the outer edge of the light-transmitting portion 2, and a matching annular protrusion can be provided on the inner wall of the mounting hole 13. This engaging structure prevents the light-transmitting portion 2 from shifting while the vehicle is in motion.

[0053] A mounting through hole 13 extending along the first direction and penetrating the first surface 11 and the second surface 12 is provided on the housing 1, and the light-transmitting portion 2 is provided through the mounting through hole 13, which simplifies the mounting method of the light-transmitting portion 2, is conducive to improving production efficiency and reducing assembly costs.

[0054] In some embodiments, see Figures 1 to 4The light-transmitting portion 2 includes a light-transmitting member 21 and a light-concentrating member 22 , and the light-transmitting member 21 and the light-concentrating member 22 are arranged along a first direction.

[0055] The light-transmitting member 21 is one of the components of the light-transmitting portion 2 , and is made of a material with good light transmittance, allowing light to pass through, and is a key link in the light propagation path.

[0056] The material and structure of the light-transmitting element 21 are not limited herein. For example, the light-transmitting element 21 may be made of optical glass or highly transparent engineering plastics. Optical glass, such as borosilicate glass, has high refractive index and low dispersion, reducing light loss during propagation. Highly transparent engineering plastics, such as polymethyl methacrylate, are lightweight and easily processed and molded. They can be formed into various complex shapes through injection molding, making them suitable for large-scale production.

[0057] In some embodiments, the surface of the light-transmitting element 21 may be treated with an anti-reflective coating, for example, using a multi-layer dielectric film coating technique. By alternately depositing layers of high-refractive-index and low-refractive-index materials on the surface of the light-transmitting element 21, this reduces reflections of light entering and exiting the light-transmitting element 21 and improves light transmittance. Furthermore, the surface may also be treated with microstructures, such as a microlens array, to provide preliminary homogenization of light as it passes through the light-transmitting element 21.

[0058] The light concentrator 22 is a component of the light-transmitting portion 2 . The light concentrator 22 can change the propagation direction and distribution of light, gather the light, make the light more concentrated, and enhance the light intensity in a specific direction.

[0059] The material and structure of the light concentrator 22 are not limited herein. For example, the light concentrator 22 can be designed as a parabolic reflector or a Fresnel lens. The light concentrator 22 can be made of a highly reflective metal material (such as aluminum) through precision die-casting or CNC machining to form a parabolic reflector, or it can be made of optical plastic through injection molding to form a Fresnel lens.

[0060] In some embodiments, the light focusing element 22 can be designed to be adjustable. For example, by providing a rotational or translational mechanism, the light focusing element 22 can be moved or its angle can be changed relative to the light transmitting element 21 and the light source. This allows for flexible adjustment of the focusing effect in different usage scenarios, such as when a vehicle is traveling under different lighting conditions or when the user has different requirements for light intensity and illumination direction.

[0061] The light-transmitting portion 2 consists of a light-transmitting element 21 and a light-concentrating element 22. The light-transmitting portion 2 has a specific optical structure hierarchy for light processing. The combination of the light-transmitting element 21 and the light-concentrating element 22 enables more precise control of light. The light-transmitting element 21 ensures the initial propagation of light, while the light-concentrating element 22 focuses the light in a specific direction and area, further concentrating the light. This design provides greater stability during vehicle operation because it integrates the light-transmitting and light-concentrating functions within the light-transmitting portion 2, making it less susceptible to vibration than discrete optical components.

[0062] In some embodiments, see Figures 1 to 4 The light-transmitting member 21 is disposed close to the first surface 11 , the light-concentrating member 22 is disposed close to the second surface 12 , and the light-concentrating member 22 extends away from the second surface 12 along the first direction to form a protrusion 221 .

[0063] Exemplarily, the first surface 11 here refers to the surface close to the light source. The light-transmitting member 21 is arranged close to the first surface 11, which is conducive to the light generated by the light source passing through the light-transmitting member 21 and irradiating the focusing member 22, thereby being focused by the focusing member 22.

[0064] The protrusion 221 is a portion of the light concentrating element 22 extending away from the second surface 12 along the first direction, and is shaped to protrude from the second surface 12 .

[0065] The specific shape structure of the raised portion 221 is not limited here. For example, the raised portion 221 can be designed to be parabolic, conical or pyramidal, etc. For example, when light passes through the parabolic raised portion 221, according to the optical properties of the parabola, it can more effectively focus the light in a specific direction, thereby improving the focusing effect. The conical or pyramidal raised portion 221 can refract and reflect light at different angles, making the distribution of light more diversified, which is suitable for situations requiring multi-angle lighting or special lighting modes. In addition, the provision of the raised portion 221 increases the surface area of ​​the concentrator 22, thereby increasing the focusing area of ​​the concentrator 22, and also increases the light output area of ​​the light emitted from the concentrator 22, which is more conducive to absorbing and transmitting light.

[0066] In some embodiments, microstructures may be provided within the raised portion 221. For example, a series of light-guiding channels may be provided along the length of the raised portion 221, and the inner walls of these light-guiding channels may be coated with a highly reflective material. After light enters the raised portion 221, it can propagate and reflect within these light-guiding channels, further controlling the light's propagation direction and enhancing the focusing effect.

[0067] In some embodiments, see Figures 1 to 4 A slope 222 is provided on a side of the light concentrating element 22 away from the second surface 12 .

[0068] The inclined surface 222 is an inclined plane disposed on the side of the concentrator 22 away from the second surface 12. This inclined surface 222 can change the angle of refraction or reflection of light on the concentrator 22, affecting the propagation direction of the light and the focusing effect. Furthermore, the provision of the inclined surface 222 increases the light output area of ​​the concentrator 22, thereby improving the lighting effect of the concentrator 22.

[0069] The specific tilt direction of the inclined surface 222 is determined based on the illumination requirements. For example, when the concentrator 22 is installed and located at the top of the storage box, the inclined surface 222 can be tilted downward to guide the light downward and better illuminate the bottom of the storage box. Of course, the inclined surface 222 can also be tilted upward or to the sides to meet different illumination requirements.

[0070] In some embodiments, the angle of the inclined surface 222 can be designed to be adjustable. By providing a small rotating mechanism on the concentrating element 22, the inclined surface 222 can be rotated around a certain axis to a certain angle. This allows for flexible adjustment of the angle of the inclined surface 222 in different usage scenarios, such as when a vehicle is traveling in different lighting environments or when the user has specific requirements for the light angle, thereby changing the direction of light refraction and the focusing effect.

[0071] In some embodiments, see Figures 1 to 4 The light-transmitting member 21 is recessed toward the second surface 12 to form a relief area 14 .

[0072] In some embodiments, see Figures 1 to 4 At least a portion of the first surface 11 located on the peripheral side of the light-transmitting member 21 is recessed toward the second surface 12 to form a relief area 14 .

[0073] The avoidance area 14 is a space formed by the light-transmitting member 21 or the first surface 11 being located on the side of the light-transmitting member 21 and being recessed toward the second surface 12. The avoidance area 14 is provided to reserve space for other components, light propagation paths or certain functions to avoid interference.

[0074] The specific position of the avoidance zone 14 is determined according to the position of the component to be avoided. Exemplarily, the avoidance zone 14 is used to avoid the light source in the storage box when the vehicle-mounted expansion dock 10 is installed. At this time, the avoidance zone 14 is set relative to the light source.

[0075] The specific shape of the avoidance zone 14 is determined by the shape of the component to be avoided. For example, it can be a circular depression, which is relatively easy to manufacture and effectively avoids some round or cylindrical components, such as reserving space for certain small sensors or special optical elements. Alternatively, it can be a rectangular depression, which is suitable for avoiding regular-shaped components, such as rectangular circuit modules. Furthermore, it can be designed with irregular shapes, customized according to the specific contours of the object to be avoided, to maximize space utilization.

[0076] In some embodiments, the edges of the avoidance zone 14 may be provided with connecting or positioning structures. For example, slots or buckles may be provided to secure the components to be avoided, ensuring that they remain stable even under vibrations during vehicle operation. Alternatively, positioning protrusions may be provided to engage with grooves on the components to be avoided, achieving precise positioning and ensuring their accurate relative position to the light-transmitting member 21 and the entire vehicle docking station 10, without affecting the normal operation of other functions.

[0077] The avoidance area 14 formed by the first surface 11 around the light-transmitting member 21 can be localized or circumferentially extend around the light-transmitting member 21. The localized avoidance area 14 can be designed to have an arc, polygon, or other shape based on specific layout requirements. The avoidance area 14 circumferentially extends around the light-transmitting member 21, and can be a ring with uniform or uneven widths to accommodate different space utilization and functional requirements.

[0078] The connection between the avoidance area 14 and the rest of the first surface 11 can be designed to have a smooth transition. For example, a rounded transition can reduce stress concentration, improve the structural strength of the housing 1, and enhance the overall appearance of the structure. Furthermore, reinforcing ribs can be provided at the connection to enhance structural stability and prevent cracks or deformation during vehicle vibrations.

[0079] The design of the clearance area 14 between the light-transmitting member 21 and the first surface 11 (the portion surrounding the light-transmitting member 21) effectively prevents spatial interference between other components within the vehicle docking station 10 and the light-transmitting member 21. For example, when a light source is installed close to the light-transmitting member 21, the clearance area 14 provides appropriate space for them, ensuring that the various components can be installed and operate normally without squeezing or colliding with each other due to insufficient space, thereby improving the assembly feasibility and operational stability of the entire device.

[0080] In some embodiments, the light-transmitting member 21 comprises a transparent polycarbonate member.

[0081] Transparent polycarbonate parts are made of a high molecular polymer material with the characteristics of high transparency, good mechanical properties and heat resistance. They can meet the needs of light transmission and adapt to temperature changes in the vehicle environment and certain external force impacts.

[0082] In some embodiments, the focusing member 22 includes a transparent polycarbonate member and diffusion powder, and the diffusion powder is disposed on the transparent polycarbonate member.

[0083] Diffusion powder is a substance that can change the propagation characteristics of light. When added to transparent polycarbonate parts, it can scatter light, change the distribution of light, and make the light more uniform and soft.

[0084] The diffusion powder can be arranged in a gradient distribution within the transparent polycarbonate member. For example, the diffusion powder concentration is lower in the polycarbonate member near the light source, and gradually increases as it moves away from the light source. This ensures that light maintains good directionality upon entering the concentrator 22, gradually scattering during propagation, achieving a more uniform light distribution. Furthermore, the distribution of the diffusion powder can be locally adjusted based on the shape of the concentrator 22 and the desired light concentration, for example, increasing the diffusion powder concentration in areas requiring wider illumination. Of course, to simplify the process, the diffusion powder can also be evenly distributed throughout the transparent polycarbonate member.

[0085] In some embodiments, the surface of the transparent polycarbonate member can be specially treated. For example, a UV-resistant coating can be applied. Because vehicles are exposed to sunlight while driving, UV rays can cause polycarbonate to age and yellow, affecting its light transmission performance. This UV-resistant coating can effectively extend the service life of the light-transmitting member 21. Furthermore, the surface can also be micro-textured by creating tiny bumps or grooves to alter the refraction properties of light on the surface, further optimizing light transmission.

[0086] By using transparent polycarbonate as the main material of the light-transmitting part 21 and the light-collecting part 22, its high transparency is fully utilized to ensure the efficient propagation of light in the light-transmitting part 2 and reduce light loss. At the same time, the good mechanical properties of the polycarbonate material enable it to withstand vibrations and impacts during vehicle driving and is not easily damaged, thereby improving the stability and reliability of the light-transmitting part 2. The addition of diffusion powder in the light-collecting part 22 can effectively improve the uniformity of light. In the absence of diffusion powder, light may be overly concentrated in certain areas, resulting in uneven lighting. The diffusion powder scatters light within the light-collecting part 22, making the light emitted from the light-collecting part 2 more uniform and soft. Whether it is used to illuminate the interface area of ​​the vehicle expansion dock 10 or as an indicator light, it can provide better visual effects and facilitate user use.

[0087] In some embodiments, see Figures 1 to 4 The distance from the light concentrating element 22 to the side of the light transmitting element 21 close to the first surface 11 is greater than or equal to 10 mm and less than or equal to 100 mm.

[0088] The specific distance from the focusing element 22 to the light-transmitting element 21 on the side close to the first surface 11 is not limited here, and can be, for example, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm, 100 mm, etc.

[0089] Here, the distance between the concentrator 22 and the light-transmitting member 21 on the side close to the first surface 11 is within the above-mentioned range, including the closest distance and the farthest distance between the light-transmitting member 21 on the side close to the first surface 11 and the concentrator 22 structure. When the distance between the concentrator 22 and the light-transmitting member 21 is too large, when the light from the light source passes through the light-transmitting member 21 and then illuminates the concentrator 22, the light is too dispersed, which is not conducive to the focusing of the concentrator 22 and is not conducive to improving the illumination brightness. When the distance between the concentrator 22 and the light-transmitting member 21 is too small, when the light from the light source passes through the light-transmitting member 21 and illuminates the concentrator 22, it is easy to form an uneven local overly bright light spot, which is not conducive to uniform illumination. Keeping the concentrator 22 and the light-transmitting member 21 at the above-mentioned distance can achieve a balance between illumination brightness and illumination uniformity.

[0090] In some embodiments, an adjustable support structure can be provided between the light concentrator 22 and the light transmissive member 21. This support structure is composed of multiple retractable rods. By rotating a nut or other similar adjustment device, the length of the rods can be precisely changed, thereby achieving fine-tuning of the distance between the light concentrator 22 and the light transmissive member 21. For example, a screw and nut combination can be used. When the nut is rotated, the screw expands and contracts within the nut, driving the light concentrator 22 to move, achieving distance adjustment.

[0091] In some embodiments, a slider is provided on the light concentrator 22 or the light transmissive member 21, and a guide rail is provided on the housing 1 of the vehicle docking station 10 or a fixed component connected thereto. The slider can slide along the guide rail and can be fixed in a specific position using a positioning pin or other locking device provided on the guide rail, thereby adjusting and fixing the distance between the light concentrator 22 and the light transmissive member 21. The guide rail can be a high-precision guide rail such as a dovetail guide rail or a linear guide rail to ensure smooth and accurate movement.

[0092] In some embodiments, see Figures 1 to 4 The vehicle-mounted expansion dock 10 includes an expansion component 3, the expansion component 3 includes an expansion body 31 and a power connector 32, the shell 1 defines a accommodating cavity 15 and an opening 16 connected to the accommodating cavity 15, the expansion body 31 is arranged in the accommodating cavity 15, and the power connector 32 passes through the shell 1 and extends into the accommodating cavity 15 for electrical connection with the expansion body 31.

[0093] The expansion component 3 is a core component of the vehicle expansion dock 10 and is mainly responsible for realizing the expansion function, including sub-components such as the expansion body 31 and the power connector 32.

[0094] The expansion body 31 is the key part of the expansion component 3, which usually contains various circuits and interfaces, and can realize expansion functions such as data transmission and device connection. For example, it can have various types of interfaces such as USB interface and HDMI interface for connecting mobile phones, tablets, mobile hard drives and other electronic devices.

[0095] The power connector 32 is used to bring an external power source into the vehicle docking station 10, providing power to the docking station body 31 and connected electronic devices. One end of the power connector is connected to the external power source, and the other end passes through the housing 1 and connects to the docking station body 31. For example, the power connector 32 can be a car cigarette lighter plug, which is suitable for most vehicles and draws power from the vehicle's cigarette lighter.

[0096] In some embodiments, to prevent the power connector 32 from loosening while the vehicle is in motion, a locking mechanism can be designed at the connector. When the power connector 32 is plugged into the vehicle's power port, the lock automatically locks, requiring a specific button to unlock and remove. This prevents poor contact due to vibration and ensures continuous and stable power supply.

[0097] The accommodating cavity 15 is an internal space defined by the housing 1 for accommodating the extension body 31. It provides a mounting location and certain protection for the extension body 31, thereby protecting it from external physical factors. The specific structure of the accommodating cavity 15 is determined by the structure of the components to be accommodated.

[0098] In addition to the opening 16 communicating with the accommodating cavity 15, the housing 1 may also be provided with other functional openings 16. For example, heat dissipation holes may be provided, the location and size of which may be designed according to heat dissipation requirements, and dust screens may be installed at the heat dissipation holes to prevent dust from entering. A maintenance port may also be provided, covered by a removable cover, to facilitate maintenance personnel to inspect and maintain the internal expansion body 31 and power connector 32.

[0099] The opening 16 is the portion of the shell 1 that is connected to the accommodating cavity 15. Its function is to allow the power connector 32 to pass through the shell 1 into the accommodating cavity 15 to achieve connection with the extended body 31. It may also facilitate other functions such as heat dissipation and wiring. The size and shape of the opening 16 can be optimized according to the size and shape of the power connector 32. The opening 16 can be designed to have a sealing gasket. When the power connector 32 passes through, the sealing gasket can prevent impurities such as dust and water vapor from entering the accommodating cavity 15. In addition, reinforcing ribs can be set around the opening 16 to increase the strength of the shell 1 at the opening 16 and avoid weakening the overall structural strength of the shell 1 due to the opening 16.

[0100] The vehicle-mounted docking station 10 includes an expansion module 3. The expansion unit 31 of the expansion module 3 is placed in the receiving cavity 15 of the housing 1. A power connector 32 extends from the outside of the housing 1 through the housing 1 into the receiving cavity 15 to establish an electrical connection with the expansion unit 31, thereby providing power to the expansion unit 31 and ensuring the normal operation of the entire docking station. The expansion unit 31's rich interface design can meet the user's needs for connecting multiple different types of electronic devices simultaneously in the vehicle, achieving the integration of multiple functions.

[0101] In some embodiments, see Figures 1 to 4The vehicle docking station 10 includes a dust cover 4 , which is connected to the housing 1 in an opening and closing manner. The dust cover 4 is used to cover or open the opening 16 .

[0102] The dust cover 4 is a component specially designed for the vehicle expansion dock 10 and is connected to the shell 1 in an openable and closable manner. Its main function is to protect the opening 16 and prevent dust, debris, etc. from entering the interior of the vehicle expansion dock 10.

[0103] The specific material of the dust cover 4 is not limited here. For example, the dust cover 4 can be made of a wear-resistant and high-temperature resistant plastic material, such as polycarbonate material. This material is not only high in strength but also has good transparency, making it convenient for users to observe the interface under the dust cover 4.

[0104] The dust cover 4 can be designed into a shape and color that matches the style of the vehicle interior.

[0105] The specific structure of the opening and closing connection between the dust cover 4 and the housing 1 is not limited here. For example, a more sophisticated hinge structure can be employed. A small stainless steel hinge is used, which offers excellent durability and flexibility, ensuring that the dust cover 4 can be opened and closed repeatedly without deformation. Furthermore, a damping device can be provided at the connection to provide a certain resistance during the opening and closing process of the dust cover 4, thereby preventing the large impact force generated by accidental opening or closing of the dust cover 4 due to vehicle vibration.

[0106] In some embodiments, a rubber sealing strip can be provided at the contact edge between the dust cover 4 and the housing 1. This rubber sealing strip can be made of a soft and elastic silicone material. When the dust cover 4 is closed, the sealing strip fits tightly against the housing 1, effectively preventing dust from entering through the gap. Furthermore, the sealing strip can be designed with a special geometric shape, such as a dovetail groove, to further enhance the sealing effect.

[0107] The design of the dust cover 4 effectively prevents dust and debris from entering the interior of the vehicle docking station 10. A vehicle generates a large amount of dust during operation. If this dust enters the docking station, it may accumulate on the circuits and connectors, causing poor contact, short circuits, and other problems. By shielding the opening 16, the dust cover 4 creates a relatively clean environment within the docking station, extending its service life and improving its reliability.

[0108] In some embodiments, see Figures 1 to 4 The extended body 31 is provided with a charging socket and / or a charging connector.

[0109] The charging socket is an interface set on the expansion body 31 for inserting the charging cable, and the charging connector is the part that directly connects to the charging cable. Both are for realizing the charging function of electronic devices and have various forms, such as USB interface, Type-C interface, etc.

[0110] In some embodiments, the charging socket and charging connector can be designed to support multiple charging protocols, such as QC (Quick Charge) protocol, PD (Power Delivery) protocol, etc. In this way, whether the user is using an Android phone that supports the QC protocol or an Apple device that supports the PD protocol, they can all be quickly charged through the car docking station 10, improving the versatility and efficiency of charging.

[0111] In some embodiments, the expansion body 31 includes an intelligent charging management circuit. This circuit automatically identifies the type and power level of the connected device and adjusts the charging current and voltage based on the device's needs, preventing damage to the device's battery from overcharging. Furthermore, when multiple devices are charging simultaneously, the intelligent charging management circuit can rationally distribute power, ensuring that each device receives a stable charging current, improving charging safety and stability.

[0112] In some embodiments, an indicator light is provided near the charging port or connector to indicate the charging status. For example, when the device is charging, the indicator light is red; when the device is fully charged, the indicator light turns green. This allows users to intuitively understand the charging status without having to frequently check the device screen.

[0113] The docking station 31 is equipped with a charging socket and / or charging connector, supporting multiple charging protocols and intelligent charging management, greatly facilitating the charging of electronic devices in the vehicle. Users no longer need to carry multiple chargers of different types; they can simply use the in-vehicle docking station 10 to charge a variety of devices. Furthermore, intelligent charging management protects device batteries and extends battery life, while charging status indicators provide users with timely updates on charging progress, enhancing convenience and safety.
