Description

Especially in scenarios of fast charging and high-speed data transmission, connecting handheld mobile devices through the USB interface is the most direct and efficient way. However, in actual use, the USB interfaces on intelligent vehicles are often designed in a lower or more concealed position on the instrument panel to maintain the neatness and aesthetics of the interior design.

[0034] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and implementation examples. It should be understood that the specific implementation examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0036] With the popularization of smart cars, the interconnection between them and handheld mobile devices has become increasingly important. As a key interaction channel, the USB interface is often designed to be relatively concealed for aesthetic considerations. It is difficult to dock in the dark or low-light environment, which affects the user experience. In response to this, on-vehicle USB interface lighting solutions have emerged in the market, but each has its limitations: one type relies on direct LED lighting. Although it improves brightness, multiple lamps need to be arranged to ensure uniform light intensity, increasing costs and complexity; the other type uses complex optical structures. Although it pursues efficient lighting, the overall volume is large, the uniformity is insufficient, and the cost is high and the maintenance is cumbersome.

[0037] Please refer to Figures 1 to 4 , an embodiment of the present utility model provides a compact guiding lighting device for an on-vehicle USB interface, which is used for guiding lighting of a USB socket 10 on a vehicle, and includes:

[0038] A circuit board 20, on which the USB socket 10 is installed and electrically connected to the circuit board 20.

[0039] A light-emitting component 30, electrically connected to the circuit board 20, and is used to provide a light source for guiding lighting of the USB socket 10, significantly improving the operation convenience in the dark or low-light environment.

[0040] A guiding lighting aperture 40, sleeved and installed on the outer peripheral side of the interface end of the USB socket 10, effectively gathering and guiding light to the target lighting area.

[0041] A light guiding aperture 50, snap-fitted and installed on the side of the guiding lighting aperture 40 close to the circuit board 20. A light splitting surface 51 is provided on the light guiding aperture 50. The light splitting surface 51 divides the light guiding aperture 50 into a light splitting part 52 and a light homogenizing part 53, which efficiently distributes and preliminarily homogenizes the light emitted by the light-emitting component 30. The light homogenizing part 53 is arranged between the guiding lighting aperture 40 and the light splitting part 52, and the light homogenizing part 53 is in contact connection with the guiding lighting aperture 40. A light driving surface 521 is provided on the side of the light splitting part 52 away from the light homogenizing part 53. The light driving surface 521 is a quadratic surface that gradually sinks in the direction close to the light homogenizing part 53. This design effectively promotes the smooth transition and efficient conduction of light in the light splitting part 52, reducing light loss. An outgoing light surface 531 is provided on the side of the light homogenizing part 53 away from the light guiding aperture 50. The light splitting part 52 is used to gradually and orderly distribute and drive the light emitted by the light-emitting component 30 into the light homogenizing part 53, ensuring the rationality and efficiency of the light distribution. The light homogenizing part 53 performs a homogenizing process on the received light, eliminating the light spot and uneven brightness phenomenon, and then softly and evenly conducts the light that has been homogenized through the outgoing light surface 531 to the guiding lighting aperture 40, realizing bright lighting in the area around the USB socket 10 and improving the user experience.

[0042] In this embodiment, a light source input port 60 is jointly formed by the end of the protruding light splitting part 52 away from the guiding illumination aperture 40 and the light homogenizing part 53, ensuring that the light emitting element 30 can be accurately positioned at the starting point of light transmission, thereby maximizing the light emitting efficiency and light utilization rate. At the same time, the light emitting element 30 is arranged at the light source input port 60, directly facing the light splitting part 52, realizing a seamless connection between the light source and the light splitting mechanism, and further improving the light guiding and distribution effect.

[0043] On the side of the guiding illumination aperture 40 close to the circuit board 20, there is a protruding mounting block 42, which provides a stable and easily positionable support surface for facilitating the sleeved installation of the light guiding aperture 50 on the mounting block 42, thereby ensuring the continuity of the light conduction path. In addition, the light guiding aperture 50 is also connected to the guiding illumination aperture 40 through elastic clamping parts 43, which not only realizes the quick installation and disassembly of the light guiding aperture 50, but also enhances the overall structural stability, ensuring good working conditions in various usage scenarios. The elastic clamping parts 43 are arranged on the longitudinally symmetrical two sides of the guiding illumination aperture 40 and fixedly installed on the guiding illumination aperture 40. This layout not only ensures the balance of the action of the elastic clamping parts 43, but also makes the force evenly distributed during the installation process, improving the assembly efficiency and smoothness. On the longitudinally symmetrical two sides of the outer periphery of the interface end of the USB socket 10, there are two limit protrusions 12. After the light guiding aperture 50 is installed in place, the elastic clamping parts 43 are also inserted between the two limit protrusions 12. The double-locking design significantly improves the connection firmness, effectively preventing accidental detachment or loosening, and ensuring the stability of the light conduction path. In addition, the light emitting surface 531 is in contact connection with the guiding illumination aperture 40, ensuring the continuity and consistency of light during transmission, and avoiding light scattering and loss. The elastic clamping part 43 includes a hook 431, and the hook 431 is in contact connection with the light driving surface 521, ensuring the accurate propagation of light in the predetermined direction while ensuring the structural connection stability.

[0044] The USB socket 10 includes a USB plug 13 and a housing 14 sleeved on the USB plug 13. The setting of the housing 14 can prevent light from leaking through the elastic sheet holes or process gaps of the USB plug 13, ensuring the integrity and aesthetics of the lighting guidance. At the same time, in order to enhance the structural connection stability and installation convenience, on the laterally symmetrical two sides of the outer periphery of one end of the housing 14 close to the interface end of the USB plug 13, there are protruding clamping blocks 11. In the inner side of the guiding illumination aperture 40, there are clamping grooves 41 adapted to the clamping blocks 11. The cooperation between the clamping blocks 11 and the clamping grooves 41 enables easy alignment and firm clamping during component assembly, not only simplifying the installation process, but also ensuring stable non-loosening during long-term use. The two limit protrusions 12 are arranged on the longitudinally symmetrical two sides of the housing 14, optimizing the structural space layout and making the structure compact.

[0045] Furthermore, the elastic card 43 is tightly engaged with the inner peripheral side of the light guide ring 50, ensuring a compact and stable connection structure and avoiding interfering with the light conduction path. The elastic card 43 further includes an arm rod 432, and the hook 431 is fixedly installed on the arm rod 432. One end of the arm rod 432 away from the hook 431 is fixedly connected to the guiding illumination aperture 40, further enhancing the integrity and stability of the overall structure and making it more reliable during installation and use.

[0046] On the side of the hook 431 close to the guiding illumination aperture 40, there is an abutting curved surface 433 adapted to the light driving surface 521, so that the hook 431 can fit more closely when contacting the light driving surface 521, further ensuring the tightness of the structural connection, effectively preventing light leakage and scattering, and at the same time further ensuring that the light can be accurately propagated in a predetermined direction, improving the directivity and clarity of the illumination effect.

[0047] On the outer peripheral side of the guiding illumination aperture 40, there is an inclined surface 44. The guiding illumination aperture 40 is trapezoidal, and the geometric size of the guiding illumination aperture 40 on the side close to the light guide ring 50 is larger than the geometric size of the guiding illumination aperture 40 on the side away from the light guide ring 50.

[0048] It should be noted that the guiding illumination aperture 40 having a larger geometric size on the side close to the light guide ring 50 can better wrap and guide the light, improving the light collection and conduction efficiency. On the side away from the light guide ring 50, the gradually decreasing geometric size helps the light to be concentrated and directionally propagated, further enhancing the light concentration and directivity of the illumination effect and improving the illumination uniformity.

[0049] Furthermore, the guiding illumination aperture 40 is a semi-transparent aperture member, and its material ensures the efficient transmission and uniform distribution of light, significantly reducing the loss of light during transmission, while enhancing the clarity and transparency of the illumination effect. In a preferred embodiment, the guiding illumination aperture 40 is a white semi-transparent aperture member. The light guide ring 50 is a transparent light guide member, and the surface of the light guide ring 50 is a smooth mirror surface. This design not only reduces the scattering and reflection of light during transmission, but also improves the light guiding property, enabling the light to be accurately propagated along a predetermined path and enhancing the focusing and directional ability of the illumination effect. In particular, the light emitting member 30 is an LED lamp bead, and this choice is based on its advantages of high efficiency, long life, and environmental protection and energy saving, providing a stable and reliable light source support for the overall lighting system. The high brightness output and excellent color temperature control ability of the LED lamp bead further improve the quality and comfort of the illumination effect.

[0050] In a preferred implementation, the number of the light emitting members 30 is 1. This design simplifies the structure of the lighting system, reduces the manufacturing cost and maintenance difficulty, and at the same time avoids the interference and color difference problems caused by multiple light sources, ensuring the unity and coordination of the illumination effect.

[0051] On the side of the light homogenizing part 53 close to the light splitting part 52, a notch 532 corresponding to the light emitting element 30 is also provided. The notch 532 is in a "V" shape. By using the principles of refraction and reflection of light, the light is redistributed and homogenized for the second time, further eliminating the problem of uneven light distribution, making the light distribution in the lighting area more uniform and soft, and further improving the quality and comfort of the lighting effect.

[0052] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principle of the present invention shall be included in the protection scope of the present invention.
