Detailed Implementation

[0032] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0033] like Figure 1 - Figure 7 As shown, the automotive laser-engraved translucent touch-sensitive interior trim provided in this embodiment includes a first component and a second component. The first component includes a PC transparent skeleton 30, the upper surface of which is covered with a 3D MESH 20, and the upper end of the 3D MESH 20 is covered with a decorative layer 10.

[0034] The second component includes a light-shielding upper housing 50, a touch-sensitive diaphragm 40 fixed on the upper part of the light-shielding upper housing 50, a main control circuit PCBA board 60 fixedly fixed inside the light-shielding upper housing 50, an RGB LED bead 70 fixedly mounted on the front of the main control circuit PCBA board 60, a thermal grease 80 fixedly connected to the back of the main control circuit PCBA board 60, a heat dissipation lower housing 90 pasted on the front of the thermal grease 80, and the light-shielding upper housing 50 fixedly connected to the heat dissipation lower housing 90 by assembly guide pins 500 reserved around the four sides. The bottom side of the heat dissipation lower housing 90 has a self-tapping screw 100, which is used for fixed-point positioning and tightening. The decorative layer 10 includes a texture layer, a skin layer, and a pattern layer.

[0035] The first component consists of a texture layer, a skin layer, a pattern layer, a 3D MESH20, and a PC skeleton assembly. The second component consists of a touch-sensitive film 40, a light-shielding upper shell 50, a main control circuit PCBA board 60 with RGB LED beads 70, a thermal grease sheet 80, and an aluminum heat dissipation lower shell 90. The second component is positioned with the first component by a guide pin 500 and then tightly fitted with the first component by a self-tapping screw 100. The overall assembly in the automotive intelligent cockpit interior parts has a visual, tactile, and sound effect that far surpasses the actual experience of ordinary automotive skin interior parts.

[0036] like Figure 4 - Figure 6 As shown, an electronic solution architecture 600 is fixedly mounted on the back of the main control circuit PCBA board 60. The electronic solution architecture 600 consists of seven modules: a protection and filtering module, a power supply module, a communication module, an RGB LED driver module, a capacitive sensing module, a main logic processing module, and a sound generation module. A ribbon cable 400 is fixedly connected to the touch sensing diaphragm 40, and the touch sensing diaphragm 40 is electrically connected to the power supply module through the ribbon cable 400. The vehicle body power supply is processed by the protection and filtering module and then sent to the power supply module. The power supply module includes three BUCK DC-DC 5V / 3A outputs and one LDO 5V / 300mA output, which are supplied to each functional sub-module respectively. The capacitive sensing module notifies the main logic processing module of the processed touch information. The capacitive sensing module synchronously drives the sound generation module to emit user prompt sound effects. The specific functions are as follows.

[0037] Protection and filtering module:

[0038] Its main function is to process the vehicle body power supply, filter out noise and interference signals in the power supply line, improve the purity and stability of the power supply, and create a good power supply foundation for the stable operation of subsequent power modules and the entire electronic solution architecture 600, so as to avoid abnormal operation, performance degradation or even damage of each module due to adverse interference factors in the power supply.

[0039] Power module:

[0040] It provides stable power outputs of different specifications: It includes 3 BUCK DCDC 5V / 3A outputs and 1 LDO 5V / 300mA output, which can accurately provide the appropriate power supply according to the different power requirements of each functional sub-module. For example, some modules with slightly higher power requirements can use the BUCK DCDC 5V / 3A output, while modules with lower power requirements can be powered by the LDO 5V / 300mA output, ensuring that each functional sub-module can obtain a stable and reliable operating voltage, ensuring that each module operates normally and realizes its corresponding functions;

[0041] Achieve efficient power conversion and distribution: After rationally converting and allocating the electrical energy input from the vehicle body, distribute it to various functional sub-modules so that different modules in the entire electronic solution architecture can obtain appropriate electrical energy in an orderly manner, and realize the overall management of the power supply of the entire system.

[0042] Communication module:

[0043] It is responsible for enabling data transmission and interactive communication between the electronic solution architecture 600 and other external devices or systems. For example, it may communicate with the vehicle's central control system to transmit relevant information such as the current working status of each module, or receive control commands from external systems, so as to ensure that the entire electronic solution architecture 600 can be integrated into the vehicle's overall intelligent operation system and work collaboratively.

[0044] RGB LED driver module:

[0045] It can drive corresponding RGB LED devices and achieve diverse lighting display effects by controlling different brightness and color combinations of the three RGB colors, which can be used to indicate different working statuses;

[0046] Capacitive sensing module:

[0047] Touch information acquisition and transmission: It can sense touch operations and accurately notify the main logic processing module of the processed touch information, so that the main logic processing module can make corresponding functional responses based on the touch situation, such as switching the light display mode or adjusting certain functional parameters according to the touch operation. It is equivalent to building an information bridge between user touch operation and system response.

[0048] Collaborative sound module operation: Synchronously drive the sound module to emit user prompt sound effects. Through the intuitive feedback of sound, the user is informed that the touch operation has been received and the relevant function is responding, which enhances the user's sense of interaction and confirmation during operation, and lets the user clearly know whether their operation is effective and the current processing status of the system.

[0049] Main logic processing module:

[0050] As the "brain" of the entire electronic solution architecture, it receives touch information from capacitive sensing modules and other components. Based on preset logic rules and program algorithms, it analyzes and judges this information, and then coordinates and controls other functional sub-modules, so that the entire system can implement various functions in an orderly manner according to user expectations and system design requirements, ensuring that the modules work together and operate efficiently.

[0051] Sound generation module:

[0052] Driven by the capacitive sensing module, it emits user prompt sound effects to inform the user of relevant operation status through sound. For example, it provides timely feedback sound effects when the user performs a touch operation, so that the user knows that the operation has been received.

[0053] In summary, these modules work together to enable the entire electronic solution architecture 600 to achieve various functions such as touch-sensing control, status prompts, and lighting effects within the vehicle, thereby improving the functionality, intelligence, and user experience of related equipment within the vehicle.

[0054] At the same time, such as Figure 4 - Figure 6 As shown, after receiving the touch information, the main logic processing module converts the corresponding communication message to notify the vehicle host, and synchronously transmits the converted lighting effect data to the RGB LED driver module. After receiving the information, the RGB LED driver module completes the corresponding lighting effect driving.

[0055] The main logic processing module transmits the converted lighting effect data to the RGB LED driver module, which then drives the corresponding lighting effect. This provides users with very intuitive feedback. In this way, various lighting effects can be achieved, such as displaying different light colors and dynamic effects based on different driving modes or vehicle statuses. This not only enhances the aesthetics of the vehicle's interior but also creates different atmospheres for the user.

[0056] like Figure 1 , Figure 3 and Figure 7 As shown, two symmetrically distributed quick-connect buckles 300 are fixedly provided on the inner side of the PC transparent frame 30. The PC transparent frame 30 is fixedly installed in the vehicle compartment through the quick-connect buckles 300. The two symmetrically distributed quick-connect buckles 300 enable the PC transparent frame 30 to be quickly fixed to the vehicle body. Compared with the traditional complicated installation method, this quick connection method can greatly improve the installation efficiency. On the vehicle production line, it can effectively reduce the installation time, increase the vehicle assembly speed, and thus reduce the production cost.

[0057] When maintenance, replacement, or inspection of the PC transparent frame 30 or related components behind it is required, the quick-connect clips make it easy for staff to remove it from the vehicle body. This feature helps to improve the convenience of vehicle after-sales maintenance. Repair personnel can remove related components without complicated tools and cumbersome steps, reducing repair time and difficulty.

[0058] like Figure 1 - Figure 3 As shown, the lower heat dissipation housing 90 has several evenly distributed heat dissipation windows 900, which correspond to the thermal grease pad 80. A dustproof mesh 910 is fixedly installed on the heat dissipation window 900. The self-tapping screw 100 passes through the lower heat dissipation housing 90, the thermal grease pad 80 and the main control circuit PCBA board 60 and extends into the interior of the light-shielding upper housing 50. The self-tapping screw 100 corresponds to the assembly guide block 500.

[0059] The heat dissipation windows 900 evenly distributed on the heat dissipation lower housing 90 correspond to the thermal grease pads 80. This is to create an effective heat dissipation channel. During the operation of the equipment, the main control circuit PCBA board 60 will generate heat. The heat is conducted to the heat dissipation lower housing 90 through the thermal grease pads 80. The heat dissipation lower housing 90 is made of aluminum, which can also play a good role in heat conduction. The heat dissipation windows 900 provide a path for hot air to escape, so that the heat can be dissipated into the air outside the equipment, thereby preventing the equipment from being damaged due to overheating, ensuring that the electronic components inside the equipment work in a suitable temperature environment, and extending the service life.

[0060] The self-tapping screws 100 serve to firmly fix the heat sink lower housing 90, the thermal grease pad 80, the main control circuit PCBA board 60, and the light-shielding upper housing 50 together. This fixing method can ensure the accurate relative position between the various components and prevent the components from loosening or shifting due to vibration, collision, or other reasons during the transportation and use of the equipment, thereby affecting the normal function of the equipment.

[0061] like Figure 1 -Figure 7 As shown in this embodiment, the principle of the automotive laser-engraved translucent touch-sensitive smart interior trim component is as follows:

[0062] During use, after receiving the touch information, the main logic processing module converts the corresponding communication message to notify the vehicle host, and simultaneously transmits the converted lighting effect data to the RGB LED driver module. After receiving the information, the RGB LED driver module completes the corresponding lighting effect driving. The vehicle body power supply is processed by the protection filtering module and then sent to the power supply module, which supplies power to each functional sub-module. The capacitive sensing module notifies the main logic processing module of the processed touch information, and the capacitive sensing module simultaneously drives the sound module to emit user prompt sound effects.
