DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] like Figures 1 to 4 As shown, in this solution, the specific structure of the air outlet is mainly described in detail. The air outlet structure is mainly used in vehicles such as cars, buses, and trucks.

[0028] A vehicle-mounted air outlet structure with a lighting function comprises: a light-emitting component 100, an air outlet guide component 200, and an intelligent control module.

[0029] Specifically, the air outlet guide assembly 200 includes a shell, which is connected to the dashboard of the vehicle. An air outlet channel is formed in the shell. One end of the air outlet channel is connected to the vehicle air conditioner for guiding the airflow blown out by the vehicle air conditioner, and the other end faces the interior of the vehicle to guide the airflow into the vehicle.

[0030] The air outlet channels in this solution can be one or more, and the number of outlet channels can be set according to the customer's preference.

[0031] The air outlet guide assembly 200 includes a driving motor 220 and an air guide 210. The driving motor 220 is disposed on the housing, and the air guide 210 is disposed in the housing and located in the air outlet channel. The air guide 210 is preferably a plurality of air guide blades connected by a connecting rod. The driving motor 220 is connected to the connecting rod, and drives the plurality of air guide blades to swing in the housing by driving the connecting rod to move, so as to change the air outlet direction of the air outlet structure, thereby achieving the purpose of adjusting the wind direction in the vehicle compartment.

[0032] The light-emitting assembly 100 is arranged on the air outlet guide assembly 200, and includes a light source module 110 and at least one light guide layer 120. The light guide layer 120 can be a planar structure or a prismatic refractive structure. The intelligent control module includes a controller connected to the vehicle system for communication and a memory for storing the light effect mode. The light source module 110 is electrically connected to the intelligent control module through a PWM dimming circuit. The controller is configured to generate corresponding dynamic light effect instructions according to the real-time angle data of the air outlet guide assembly 200, so that the light effect of the light-emitting assembly 100 presents a flowing light effect linked to the air outlet direction.

[0033] For example, refer to Figure 1 , when the wind guide blades Figure 1 When the light-emitting component 100 is swung to the left, the light-emitting component 100 presents a leftward flowing light effect; similarly, when the wind guide blade is Figure 1 When the light emitting component 100 is swung to the right, the light emitting component 100 presents a rightward flowing light effect.

[0034] In this solution, by integrating the light-emitting component 100 into the vehicle air outlet structure, and the light-emitting component 100 can generate corresponding dynamic light effects according to the change of the air outlet direction, the dynamic interaction between the dynamic light effect and the air outlet direction is realized. This not only increases the sense of technology and personalized experience of the vehicle's internal environment, but also improves the safety and comfort of night driving.

[0035] The present solution also includes a bracket assembly 300, through which the light-emitting assembly 100 is connected to the air outlet guide assembly 200, and the bracket assembly 300 includes: a bracket body 310, which is detachably connected to the air outlet guide assembly 200; a panel 320, which is snapped onto the bracket body 310, and the panel 320 has an arc-shaped supporting surface adapted to the surface curvature of the light guide layer 120, and the arc-shaped supporting surface is pressed against the surface of the light guide layer 120; a bracket 330, which is arranged on the bracket body 310 and is used to provide support for the light guide layer 120; a buffer member 340, which is connected between the bracket body 310 and the panel 320, and is used to provide a buffer between the light guide layer 120 and the bracket assembly 300.

[0036] The bracket assembly 300 is configured as a supporting structure of the light emitting assembly 100 on the air outlet structure. The detachable connection between the bracket body 310 and the air outlet guide assembly 200 provided thereon can be achieved by bolt connection. Specifically, a threaded hole is provided on the air outlet guide assembly 200, and a bolt through hole is provided on the bracket body 310. The connection between the two is achieved by passing one end of the bolt through the bolt through hole and screwing it into the threaded hole.

[0037] The panel 320 is configured as a fixing structure of the light guide layer 120, and the arc-shaped supporting surface provided thereon and adapted to the surface curvature of the light guide layer 120 is used to make the light guide layer 120 and the panel 320 fit more closely, so that the light guide layer 120 can be stably installed on the bracket assembly 300. The clamping structure between the panel 320 and the bracket body 310 can be realized by providing a clamping tongue on the panel 320 and providing a clamping groove adapted to the clamping tongue on the bracket body 310. Through the clamping between the clamping tongue and the clamping groove, the panel 320 can be firmly fixed on the bracket body 310.

[0038] The bracket 330 is configured as a supporting component of the light guide layer 120, and fixes the light guide layer 120 together with the panel 320. The buffer 340 is preferably made of a silicone rubber material, and its presence further enhances the durability and reliability of the system and prevents damage caused by vibration.

[0039] The light-guiding layer 120 includes: a light-transmitting plate 121, which is arranged in the bracket 330; a light-collecting plate 122, which covers the end of the light-transmitting plate 121 away from the bracket 330, and the light-collecting plate 122 has a prism structure; an anti-glare layer, which is arranged at the end of the light-collecting plate 122 away from the light-transmitting plate 121, and the anti-glare layer is a nano-silicon oxide coating with a diffuse reflectivity of 15% to 30%.

[0040] The multi-layer structure of the light-transmitting plate 121, the light-collecting plate 122 and the anti-glare layer improves the propagation efficiency and uniformity of the light emitted by the light source module 110, while reducing interference with the driver's vision and enhancing driving safety.

[0041] In this scheme, the generation of dynamic light effect instructions includes: collecting the deflection angle θ of the air guide 210 in real time through the Hall sensor; calculating the light effect flow speed v=Kθ+b according to the angle θ, where K is the proportional coefficient and b is the reference speed; decomposing the light flow direction into Y-axis components, where the Y-axis component is positively correlated with the horizontal deflection angle of the air guide 210.

[0042] For example, when the proportional coefficient k is 0.2, when the wind guide 210 deflects 30°, the Hall sensor transmits the angle data to the controller. At this time, according to the formula v=0.2θ+5 (where θ is the angle value), the light flow speed is calculated to be 11 cm / s. By PWM modulating the RGBW LED, a gradient light band synchronized with the wind direction is generated on the light guide layer 120.

[0043] In this solution, the direction of the Y-axis component is defined as Figure 1 The Hall sensor collects angle information in real time and adjusts the light flow speed and direction accordingly, achieving a close linkage between the light effect and the air outlet direction, providing a more natural and harmonious visual experience.

[0044] The light source module 110 includes: a circuit board 111, which is disposed in the bracket body 310; and a power supply 112, which is disposed in the bracket body 310 and electrically connected to the circuit board 111 to provide a power source for the circuit board 111. By integrating the circuit board 111 and the power supply 112 in the bracket body 310, wiring is simplified, and the compactness and installation convenience of the system are improved.

[0045] The light effect modes include: breathing mode: the brightness changes periodically according to the sine curve, and the frequency can be adjusted in the range of 0.5-2Hz; music rhythm mode: through FFT analysis of audio signals, the low frequency band is mapped to light intensity changes, and the high frequency band is mapped to color changes; safety warning mode: when the driver's fatigue state is detected, a high-frequency flashing red light warning is triggered. In this solution, different types of light effect modes such as breathing mode, music rhythm mode and safety warning mode are realized through PWM modulation, which meets the needs of users in different situations and enhances the diversity and fun of user experience.

[0046] The drive motor 220 adopts a stepper motor, and its control circuit includes: an angle feedback module, which adopts a 14-bit absolute encoder; a current monitoring module, which detects the change of motor coil current in real time and triggers the protection mechanism when the abnormal current fluctuation exceeds the set threshold; a temperature compensation unit, which adjusts the motor drive current according to the ambient temperature, and the compensation coefficient is 0.5% / ℃.

[0047] The stepper motor is equipped with high-precision encoder, current monitoring and temperature compensation functions to ensure the accuracy and stability of the motor operation, extend its service life and reduce maintenance costs.

[0048] This solution also includes: an environmental perception module, including a light sensor and a cabin infrared camera; the controller automatically adjusts the light effect brightness according to the ambient light intensity; when it is detected that a passenger is looking at the air outlet area, the light effect contrast is automatically enhanced to 120% to 150%.

[0049] By automatically detecting the ambient light intensity and passenger attention, the lighting effect can be intelligently adjusted, which not only improves comfort but also avoids unnecessary energy waste.

[0050] The intelligent control module includes: an OTA upgrade interface that supports updating the light effect algorithm library through the vehicle Ethernet; a safety isolation circuit that uses an optocoupler isolator to electrically isolate the vehicle communication bus from the lighting control circuit. The OTA upgrade interface supports OTA upgrades to facilitate software updates, while electrical isolation effectively protects the system from external interference, enhancing the reliability and safety of the overall system.
