Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to an instrument panel assembly and a vehicle. Background Technology

[0002] As the automotive industry continues to advance in technology, users are paying increasing attention to aesthetics and quality while focusing on the basic performance of vehicles. This is especially true as cars serve as "mobile intelligent spaces," with passengers demanding higher standards for the driving and passenger environments within the cabin. Ambient lighting, combining cabin decoration with illumination functions, creates personalized, intelligent, and high-end effects through variations in color and brightness, meeting the growing needs of users.

[0003] Currently, ambient lighting is usually installed on door panels and seats. Since door panels are frequently opened and closed and seats need to be moved frequently, the ambient lighting installed on them may malfunction due to repeated mechanical stress, such as broken wires or loose connectors. Once a problem occurs, repair is relatively complicated, especially when the light fixture is embedded inside the seat, which may require disassembling a large number of components for inspection or replacement. Utility Model Content

[0004] One objective of this utility model is to provide an instrument panel assembly to solve the problem that ambient lights arranged on door panels and seats in the prior art are prone to failure; the second objective is to provide a vehicle.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An instrument panel assembly includes: an air vent panel having an opening; an ambient light assembly disposed on a first side of the air vent panel, the ambient light assembly including a plurality of lamps corresponding to the opening; and a light-transmitting component disposed on a second side of the air vent panel, the first side and the second side of the air vent panel being disposed opposite to each other, the light-transmitting component blocking the plurality of openings, the light-transmitting component including a light-diffusing element and a transparent element, the light-diffusing element being disposed close to the ambient light assembly, the transparent element being disposed on the side of the light-diffusing element away from the ambient light assembly, the light-diffusing element having a light-incident surface facing the lamps, the light-diffusing element being used for light diffusing, and the transparent element being used for reflecting light.

[0007] Based on the aforementioned technical methods, the ambient lighting assembly is integrated into the air vent panel. Since the air vent panel is fixed, the ambient lighting assembly is virtually immune to wire breakage or loose connectors, reducing the risk of damage caused by mechanical movement. This lowers the likelihood of malfunctions and significantly improves the lifespan and stability of the ambient lighting, effectively solving the problem of ambient lighting malfunctions caused by placing it on door panels and seats in existing technologies. Furthermore, the air vent panel not only vents air but also provides ambient lighting, enhancing the interior aesthetics and adding a modern and technological feel to the vehicle. The light-diffusing element allows most of the light to pass through, resulting in brighter, softer, and more uniform light with minimal light loss, effectively achieving uniform light distribution. The uniformly diffused light is then reflected by a transparent element and enters the viewer's eyes, allowing the user to see the color of the light source. This makes the ambient lighting colors more vibrant and realistic, enhancing the aesthetics and personalized atmosphere of the vehicle interior.

[0008] Furthermore, the bottom surface of the transparent component has several inwardly recessed optical teeth, which are spaced apart along the extending direction of the transparent component.

[0009] Based on the above technical means, the transparent part can act as a light-emitting carrier, which will form a uniform light-emitting body. The bottom of the transparent part is provided with light teeth. After the light passes through the light teeth, the pattern of the light teeth is reflected and enters the human eye. The user can see the crystal pattern through the transparent part.

[0010] Furthermore, the light-incident surface includes a first light-incident surface segment and a second light-incident surface segment arranged at an angle. The first light-incident surface segment and the second light-incident surface segment form a protrusion protruding towards the lamp body. The first light-incident surface segment and the second light-incident surface segment are arranged alternately along the extension direction of the light-transmitting component, and the intersection line of the first light-incident surface segment and the second light-incident surface segment is set directly opposite the lamp body.

[0011] Based on the above technical means, the several protrusions on the light-incident surface are generally wavy in shape, which can increase the light uniformity effect and ensure that the light from the LED can pass through the transparent part evenly after passing through the light uniform component.

[0012] Furthermore, the light-diffusing component is made of white plastic, and the transparent component is made of transparent plastic. The light transmittance of the light-diffusing component is less than that of the transparent component.

[0013] Furthermore, the dashboard assembly also includes a waterproof cover fixed to the first side of the air vent panel, and the ambient light assembly is fixed to the side of the waterproof cover facing the light-transmitting component.

[0014] Based on the above technical means, the waterproof cover can prevent condensation on the air outlet panel from flowing onto the ambient light assembly, protecting the ambient light assembly, achieving waterproof and dustproof protection, and preventing damage to the ambient light assembly after water ingress.

[0015] Furthermore, the opening is equipped with light-blocking ribs corresponding to each lamp body.

[0016] Based on the above technical means, the setting of the light-blocking rib can prevent light leakage and ensure that all the light emitted by the lamp body passes through the opening of the air outlet panel.

[0017] Furthermore, the dashboard assembly also includes a control box, and the ambient lighting assembly also includes a PCB board with several lamps mounted on it. The PCB board is communicatively connected to the control box.

[0018] Based on the above technical means, since the width of the PCB board is already at its limit, it is impossible to place control chips and other components on the PCB board. Instead, a control box is used to communicate with the whole vehicle and control the ambient lighting assembly. The control logic is concentrated in the control box, which facilitates modular design and is conducive to the rapid development and integration of new functions.

[0019] A vehicle comprising: the aforementioned dashboard assembly.

[0020] Furthermore, the vehicle also includes a control unit, which comprises a cockpit control module, an ambient lighting control module, and a human-machine interaction module. The ambient lighting control module is communicatively connected to the cockpit control module, and the human-machine interaction module is also communicatively connected to the cockpit control module. The human-machine interaction module is used to collect user information.

[0021] Based on the aforementioned technical means, the cockpit control module is responsible for the user's large screen, voice Bluetooth, gesture operation, remote control, and other operations, as well as the sensing and transmission of sensor signals to the bus. The ambient lighting control module interacts with the cockpit control module via a private CAN bus to ensure the robustness and real-time performance of signal transmission. The human-machine interface module collects ambient light signals, user voice or gesture signals, signals from vehicles approaching from behind, and other signals, and sends them to the cockpit control module for processing. After processing, the cockpit control module communicates with the ambient lighting control module via its internal CAN bus, and the ambient lighting control module controls the color and brightness of the LEDs.

[0022] Furthermore, the ambient lighting control module includes a CAN transceiver, a crystal oscillator circuit, a general-purpose input / output circuit, a download interface circuit, an MCU chip, an LDO chip, a filter anti-reverse circuit, an ADC sampling circuit, a hardware watchdog circuit, and an LED series circuit. The CAN transceiver is connected to the cockpit control module for communication. The MCU chip is connected to the CAN transceiver, crystal oscillator circuit, general-purpose input / output circuit, download interface circuit, LDO chip, ADC sampling circuit, and hardware watchdog circuit for communication. The LED series circuit is connected to the MCU chip via the SPI bus. The filter anti-reverse circuit and ADC sampling circuit are used for communication with the battery power supply circuit.

[0023] Based on the above technical means, the ambient light control module is composed of LEDs connected in series, which integrate LED control and driver chips. Compared with ordinary RGB LEDs, LEDs are based on twisted-pair differential circuits and can achieve automatic temperature compensation and self-diagnosis functions through SPI communication. The circuit design is simple, which is more advantageous for some narrow spaces with extreme shape requirements, and has better EMC performance.

[0024] The beneficial effects of this utility model are:

[0025] A dual-color injection molded part supporting crystal three-dimensional illumination is integrated into the air vent panel. The dual-color injection molded part is located at the lower part of the air vent of the air vent panel. The ambient light assembly and control box are fixed to the air vent panel after being fixed with a waterproof cover. This solves the problem that existing crystal ambient lights cannot truly emit "crystal" light. Furthermore, the ambient light control module is directly controlled through the cockpit control module, and the ambient light can respond in time. This solves the risk of ambient light delay that may be caused by the existing control strategy requiring the body module to control it. It is highly competitive and can be mass-produced at low cost.

[0046] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0047] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0048] This embodiment proposes an instrument panel assembly, which is an important component inside a vehicle. It not only houses various instruments and control devices but also significantly impacts the vehicle's overall design, functionality, and user experience. For example... Figures 1 to 7 As shown, the dashboard assembly includes: an air vent panel 1, an ambient lighting assembly 2, and a light-transmitting component 3. The air vent panel 1 has an opening; the ambient lighting assembly 2 is disposed on the first side of the air vent panel 1, and the ambient lighting assembly 2 includes a plurality of lamp bodies 201 corresponding to the opening; the light-transmitting component 3 is disposed on the second side of the air vent panel 1, the first side and the second side of the air vent panel 1 are arranged opposite to each other, the light-transmitting component 3 covers the plurality of openings, the light-transmitting component 3 includes a light-diffusing element 301 and a transparent element 302, the light-diffusing element 301 is disposed close to the ambient lighting assembly 2, the transparent element 302 is disposed on the side of the light-diffusing element 301 away from the ambient lighting assembly 2, the light-diffusing element 301 has a light-incident surface 3011 facing the lamp body 201, the light-diffusing element 301 is used for light diffusing, and the transparent element 302 is used for light reflection.

[0049] By utilizing the technical solution of this embodiment, the ambient lighting assembly 2 is integrated onto the air vent panel 1. Since the air vent panel 1 is fixed, the ambient lighting assembly 2 is virtually immune to wire breakage or connector loosening, reducing the risk of damage caused by mechanical movement. This lowers the likelihood of malfunctions and significantly improves the lifespan and stability of the ambient lighting, effectively solving the problem of ambient lighting malfunctions caused by its placement on door panels and seats in existing technologies. Furthermore, the air vent panel 1 not only vents air but also provides ambient lighting, enhancing the interior aesthetics and adding a modern and technological feel to the vehicle.

[0050] Furthermore, the light-diffusing element 30 allows most of the light to pass through, making the light brighter, softer, and more uniform with minimal light loss, thus achieving the effect of light uniformity. The uniformly diffused light is reflected into the human eye by the transparent element 302, allowing the user to see the color of the light source through the transparent element 302. This makes the ambient light colors more vibrant and realistic, enhancing the aesthetics and personalized atmosphere inside the car.

[0051] In this embodiment, the bottom surface of the transparent component 302 has a plurality of inwardly recessed light teeth 3021, which are spaced apart along the extending direction of the transparent component 302. The transparent component 302 can act as a light-emitting carrier, forming a uniform light-emitting body. The bottom of the transparent component 302 is provided with light teeth 3021. After light passes through the light teeth 3021, it is reflected to form the pattern of the light teeth 3021 and enters the human eye. The user can see the crystal pattern through the transparent component 302.

[0052] Furthermore, the parameters of the optical teeth 3021 include the length d of the bottom edge of the optical teeth 3021, the height h, and the spacing g between the optical teeth 3021. When d is within a certain range, the higher h is, the more and wider the reflected light will be. In other words, the pattern shape will be more prominent and eye-catching, allowing for more freedom in the design and a more refined transparent texture.

[0053] In this embodiment, the light-incident surface 3011 includes a first light-incident surface segment 3012 and a second light-incident surface segment 3013 arranged at an angle. The first light-incident surface segment 3012 and the second light-incident surface segment 3013 form protrusions protruding towards the lamp body 201. The first light-incident surface segment 3012 and the second light-incident surface segment 3013 are arranged alternately along the extension direction of the light-transmitting component 3, and the intersection line of the first light-incident surface segment 3012 and the second light-incident surface segment 3013 is set directly opposite to the lamp body 201. The protrusions of the light-incident surface 3011 are generally wavy, which can increase the light uniformity effect and ensure that the light from the LED can be uniformly emitted through the transparent component 302 after passing through the light uniform component 301.

[0054] Furthermore, the cross-section of the convex part is an isosceles triangle, with the apex of the isosceles triangle facing the center of the light source of the lamp body 201. The vertex angle of the isosceles triangle is α, and the base angle is β. The values ​​of the vertex angle and the base angle need to take into account the distance between the lamp body 201 and the light-diffusing element 301, as well as the distance between the lamp bodies 201, based on experience and evaluation using Speos professional optical simulation software. Speos is an abbreviation for Simulation of Optical Systems.

[0055] In this embodiment, the light-diffusing component 301 is white plastic and the transparent component 302 is transparent plastic. The light transmittance of the light-diffusing component 301 is less than that of the transparent component 302. At this time, the light-transmitting component 3 is a two-color injection molded part, which serves as the carrier for light emission.

[0056] Furthermore, the light-diffusing component 301 and the transparent component 302 are made of PC, which stands for polycarbonate. Low-transmittance PC appears milky white and serves to even out the light, while high-transmittance PC exhibits a highly transparent crystal-like texture, presenting a uniformly luminous crystal-like appearance – the most noticeable aspect for users. The two-color injection molded part is manufactured using a two-color injection molding process from low-transmittance milky white material and high-transmittance transparent material. The milky white material includes a substrate and a light diffusing agent. The substrate is PC, and the light diffusing agent is an organic light diffusing agent, styrene resin. The light diffusing agent acts as a light-diffusing layer. Being transparent or semi-transparent, it allows most of the light to pass through. Utilizing the difference in refractive index between the light diffusing agent and the substrate, the light emitted by the lamp body 201 undergoes multiple refractions, resulting in a brighter, softer, and more uniform light with minimal light loss, thus achieving the effect of light uniformity.

[0057] Furthermore, the two-color injection molded part is bonded to the air outlet panel 1. The two-color injection molded part has adhesive posts, and the air outlet panel 1 has adhesive holes that mate with the adhesive posts. The adhesive posts are evenly arranged, and the bonding of the adhesive posts and adhesive holes can enhance the bonding strength between the two-color injection molded part and the air outlet panel 1.

[0058] Specifically, the ends of the two-color injection molded parts are provided with two ribs, which have positioning protrusions. The positioning protrusions on the two ribs serve as the main positioning and auxiliary positioning functions, positioning the two-color injection molded parts left and right, up and down, and front and back, ensuring the dimensional positioning stability of the exit panel and the two-color injection molded parts.

[0059] Furthermore, the two-color injection molded part and the air outlet panel 1 are fitted with a clearance, and anti-noise felt needs to be added between the two to prevent noise problems in the later stage.

[0060] In this embodiment, the dashboard assembly also includes a waterproof cover 4 fixed to the first side of the air vent panel 1, and the ambient light assembly 2 is fixed to the side of the waterproof cover 4 facing the light-transmitting component 3. The air vent on the air vent panel 1 is located at the ambient light assembly 2. The waterproof cover 4 can prevent condensation on the air vent panel 1 from flowing to the ambient light assembly 2, protecting the ambient light assembly 2, achieving waterproof and dustproof protection, and preventing damage to the ambient light assembly 2 after water ingress.

[0061] Furthermore, the waterproof cover 4 is connected to the air outlet panel 1 by snap-fit ​​and bolt fastening. The waterproof cover 4 and the air outlet panel 1 are fixed together by a double fixing method, which makes the connection between the waterproof cover 4 and the air outlet panel 1 more stable and reliable, and can resist vibration and impact.

[0062] In this embodiment, a light-blocking rib is provided at the opening corresponding to each lamp body 201. The light-blocking rib prevents light leakage and ensures that all the light emitted by the lamp body 201 passes through the opening of the air outlet panel 1. After the light-blocking rib is set at the opening, a window is formed on the air outlet panel 1 corresponding to each lamp body 201. In other words, under the premise of ensuring the intensity of the air outlet panel 1 and the optical uniformity of the crystal ambient light, a window is opened on the area of ​​the air outlet panel 1 corresponding to each lamp body 201, and a light-blocking rib is formed around the window.

[0063] In this embodiment, the dashboard assembly also includes a control box 5, and the ambient lighting assembly 2 includes a PCB board 202. Several lamp bodies 201 are mounted on the PCB board 202, which is communicatively connected to the control box 5. Since the width of the PCB board 202 is already at its design limit, it is impossible to arrange control chips and other components on it. The control box 5 is responsible for communicating with the vehicle and controlling the ambient lighting assembly 2, concentrating the control logic within the control box. This facilitates modular design and allows for rapid development and integration of new functions. The connectors of the control box 5 need to consider the ergonomics of the final assembly process and be placed in suitable locations for easy connection to the vehicle's wiring harness.

[0064] Furthermore, to ensure ease of installation and maintenance, the control box 5 is connected to the waterproof cover 4 with screws, thus forming a waterproof cover assembly. This allows for maintenance and replacement of the ambient lights without disassembling the dashboard, providing excellent maintainability. The waterproof cover assembly is then connected to the air vent panel 1 via clips and screws. The air vent grille is also installed on the air vent panel 1, forming a panel ambient light assembly. The panel ambient light assembly is then connected to the dashboard and instrument frame to form the dashboard assembly.

[0065] Specifically, the control box 5 connects the PCB board 202 and the vehicle wiring harness. The control box 5 is very close to the PCB board 202 and is connected via a twisted pair cable. It is mainly responsible for receiving and analyzing the vehicle's infotainment system signals to drive the LEDs on the PCB board 202 to turn on and off.

[0066] Furthermore, the waterproof cover 4 is welded to the PCB board 202. The waterproof cover 4 is provided with welding posts, which pass through the limiting holes on the PCB board 202 for wave soldering, thereby fixing the waterproof cover 4 and the PCB board 202 together. The welding posts are provided with positioning structures to ensure that the welding position between the waterproof cover 4 and the PCB board 202 is accurate.

[0067] Furthermore, in order to prevent the SMT process from becoming unstable due to the excessive length of the PCB board 202, a board splitting operation is performed according to the required total length of the PCB board 202. The PCB board 202 includes multiple board segments, and the signals between the board segments are connected by flexible flat cables.

[0068] In this embodiment, the lamp body 201 is an LED, which is responsible for emitting light. The light emission angle is 120 degrees. The closer to the center line of the LED, the stronger the light. The light homogenizer 301 can homogenize the light emitted by the LED from orderly light emission to uniform light emission. The transparent component 302 achieves the effect of three-dimensional crystal overall light emission.

[0069] Furthermore, to ensure uniform overall light emission, the LEDs are arranged at equal intervals to guarantee uniform light mixing.

[0070] This embodiment also proposes a vehicle including the aforementioned dashboard assembly.

[0071] In this embodiment, as Figure 9 As shown, the vehicle also includes a control unit, which comprises a cockpit control module 6, an ambient lighting control module 7, and a human-machine interface module 8. The ambient lighting control module 7 and the human-machine interface module 8 are communicatively connected. The human-machine interface module 8 is used to collect user information. The cockpit control module 6 is responsible for the user's large screen, voice Bluetooth, gesture operation, remote control, and other operations, as well as sensing sensor signals and transmitting them to the bus. The ambient lighting control module 7 interacts with the cockpit control module 6 via a private CAN bus to ensure robust and real-time signal transmission. The human-machine interface module 8 collects ambient light signals, user voice or gesture signals, rear vehicle signals, and other signals and sends them to the cockpit control module 6 for processing. After processing, the cockpit control module 6 communicates with the ambient lighting control module 7 via its internal CAN bus. The ambient lighting control module 7 controls the color and brightness of the LEDs.

[0072] In this embodiment, as Figure 8 As shown, the ambient lighting control module 7 includes a CAN transceiver 701, a crystal oscillator circuit 702, a general-purpose input / output circuit 703, a download interface circuit 704, an MCU chip 705, an LDO chip 706, a filter anti-reverse circuit 707, an ADC sampling circuit 708, a hardware watchdog circuit 709, and an LED series circuit 710. The CAN transceiver 701 communicates with the cockpit control module 6. The MCU chip 705 communicates with the CAN transceiver 701, crystal oscillator circuit 702, general-purpose input / output circuit 703, download interface circuit 704, LDO chip 706, ADC sampling circuit 708, and hardware watchdog circuit 709. The LED series circuit 710 communicates with the MCU chip 705 via an SPI bus. The filter anti-reverse circuit 707 and ADC sampling circuit 708 are used to communicate with the battery power supply circuit 9. The download interface circuit 704 is specifically an SWD download interface circuit 704. The ambient light control module 7 is composed of LEDs connected in series, which integrate LED control and driver chips. Compared with ordinary RGB LEDs, the LEDs are based on a twisted pair differential circuit and can achieve automatic temperature compensation and self-diagnosis functions through SPI communication. The circuit design is simple and has more advantages for some narrow spaces with extreme shape requirements, and has better EMC performance.

[0073] Specifically, such as Figures 9 to 11As shown, the vehicle's human-machine interface module 8 collects external user information and sends it to the cockpit control module 6 via the bus. The cockpit control module 6 then processes the information and interacts with the ambient lighting control module 7 via CAN communication. The circuit of the ambient lighting control module 7 can use commercially available mature circuits. After receiving the signal from the cockpit control module 6, the ambient lighting control module 7 drives the brightness and color of each LED connected in series through the above circuit. This control method has a simple signal circuit and cost advantage. It can realize complex functions including but not limited to music rhythm, door opening warning, flowing water and meteor, adaptive brightness adjustment, driving mode linkage, game linkage, door opening welcome, Bluetooth voice linkage, etc. In addition, the crystal texture multi-pattern effect can greatly enhance the luxurious texture of the cabin space and realize a true "crystal" ambient lighting.

[0074] Furthermore, the ambient light control module 7 is powered by the vehicle's battery. In order to prevent power loss when the battery is turned off, the dark current during sleep needs to be less than a certain value. This function is also achieved by the MCU chip 705 shutting down unnecessary chips in sleep mode.

[0075] Furthermore, the voltage of the vehicle battery is unstable due to varying operating environments and is subject to both low-frequency and high-frequency interference. When power enters the vehicle, it first needs to pass through a 707 filter circuit to remove its own ripple and noise, and to prevent damage to the modules from reverse connection. The external power supply is still sampled by the ADC, and the MCU chip 705 monitors the external voltage in real time. If overvoltage or undervoltage occurs, the load response and some circuits will be shut down. After filtering and reverse protection, an LDO chip 706 is used for linear voltage regulation. This chip has low noise, low ripple, and provides a stable and clean voltage for the MCU chip 705, while also being relatively inexpensive.

[0076] Furthermore, the hardware watchdog circuit 709 can prevent the embedded software from crashing due to faults, electromagnetic interference, or software bugs during operation, thus preventing the product from entering a dead state. Although the MCU chip 705 has a software watchdog, if it crashes before program initialization or crashes after the software watchdog is disabled, the watchdog function will fail. Therefore, a hardware watchdog circuit 709 is added externally to the MCU chip 705. The external hardware watchdog circuit 709 is mainly controlled by an external chip and will not stop once it is started without power, thus ensuring higher reliability.

[0077] Furthermore, the peripheral circuit of the MCU chip 705 includes a CAN transceiver 701, which is mainly responsible for the CAN signal transmission and reception conversion between the MCU chip 705 and the cockpit control module 6.

[0078] Furthermore, the external crystal oscillator circuit 702 is highly accurate and easily adjustable, providing a stable operating clock signal for the MCU. The general-purpose input / output circuit 703 is responsible for signal interaction between the MCU and external devices; the SWD download interface circuit 704 is a simple single-wire debugging and programming interface that can quickly debug the MCU software and verify its functions; the LEDs and the MCU communicate and interact via the SPI proprietary protocol, connected in series with two wires, receiving signals from the MCU to achieve individual control of the color and brightness of each LED.

[0079] The following are examples of control logic diagrams for several common functions of ambient lighting:

[0080] Adaptive dimming function: When it is night or the light is weak, the ambient light may reflect the image through the front door glass or the windshield, which may affect the driver's driving safety. The ambient light signal can be collected and then sent to the cabin control module 6 and then to the ambient light control module 7 to adaptively adjust the brightness of the ambient light, thereby realizing the adaptive dimming function.

[0081] Door opening warning: The system detects the signal of an approaching vehicle from behind using external radar, transmits it to the ambient light control module 7, and then activates the ambient light flashing reminder function to prevent "door opening kill".

[0082] Music Rhythm: The cockpit control module 6 analyzes the energy value of music playback and drives the number and brightness of LEDs to blink or flow through high-speed CAN communication. This eliminates the need for the ambient light control module 7 to have its own audio decoder, enabling the music rhythm function to be implemented at low cost.

[0083] Bluetooth voice and gesture function: The ambient lighting effect is realized by the sensor of the human-computer interaction module 8 to sense the user's operation, making the cabin more technological.

[0084] The functions of ambient lighting are not limited to the ambient lighting control logic listed above.

[0085] In related technologies, ambient lighting uses patterned covers to achieve a crystal effect. While this achieves the desired crystal-like design, the complex structure is often limited by shape and space constraints. Furthermore, it only emits light from one side, allowing only one-sided viewing, and lacks the overall luminous effect of a three-dimensional crystal. Therefore, it cannot be considered a true crystal ambient light. Additionally, ambient lighting control requires the vehicle's control module. As ambient lighting functions become increasingly complex, its relationship with the vehicle's infotainment system grows. Often, the control modules for user voice, Bluetooth, and large-screen operation are not part of the vehicle's control module. Communication gateway conversion is required between the vehicle's infotainment system and the vehicle's control module, which poses a risk of latency for complex functions involving multiple LEDs.

[0086] To address the shortcomings of existing crystal ambient lights in achieving uniform crystal illumination and electronic functional solutions, this embodiment integrates a dual-color injection molded part that supports three-dimensional crystal illumination on the air vent panel 1. The dual-color injection molded part is located at the lower part of the air vent of the air vent panel 1. The ambient light assembly 2 and the control box 5 are fixed to the air vent panel 1 after being fixed to the waterproof cover 4. This solves the problem that existing crystal ambient lights cannot truly emit "crystal" light. Furthermore, the ambient light control module 7 is directly controlled by the cockpit control module 6, allowing the ambient light to respond promptly. This eliminates the risk of ambient light delay that may result from existing control strategies requiring the vehicle body module to control the ambient light. This approach is highly competitive and can be mass-produced at low cost.

[0087] Furthermore, the air vent panel 1 is the core surface of the instrument panel, the most central area that cabin users can perceive. This area is also one of the most complex structures in the interior. The instrument panel assembly also includes air vent blades, air ducts, steering column, CCB, steering wheel, upper and lower instrument panel frames, slush-molded parts, side trim pieces, vehicle infotainment screen, outer coverings, door trim panels, etc. These structures can all be implemented using existing technologies and will not be described in detail here. Integrating dual-color injection-molded parts and ambient lighting assembly 2 onto the air vent panel 1 allows for a layout with minimal space requirements, and can be extended and applied to other models with similar illuminated air vent designs.

[0088] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
