Note that, in the accompanying drawings, the same reference numerals are given to components having substantially the same or similar structures and functions, and repeated descriptions thereof will be omitted.

[0032] To address the issue of lightweighting vehicle electronic control devices, this application provides the following technical solutions:

[0033] In one embodiment, Figure 1 As shown, an electric control device includes: a leather layer 1, a conductive circuit 3, a touch capacitor 4, and an insulating layer 5;

[0034] The conductive circuit 3 is attached to the inner surface of the leather layer 1, the touch capacitor 4 is attached to the conductive circuit 3, and a key area 2 is provided on the outer surface of the leather layer at a position corresponding to the touch capacitor 4;

[0035] The conductive line 3 is used to transmit the electrical signal generated when the touch capacitor 4 is pressed;

[0036] The insulating layer 5 at least covers the surfaces of the conductive circuit 3 and the touch capacitor 4 to shield the conductive circuit 3 and the touch capacitor 4 .

[0037] The leather layer is wrapped around the outer surface of the electronic control device and is used to carry the conductive circuit printed on its inner surface. Optionally, TPO (Thermoplastic Polyolefin) leather is used as the base material of the leather layer.

[0038] Preferably, translucent TPO leather is used as the base material of the leather layer. Translucent TPO leather not only provides a good appearance texture and a good touch, but also can realize the touch function, thereby enhancing the vehicle occupant experience. Compared with PVC (polyvinyl chloride) leather, there are more plasticizers and other additives, and leather precipitates may affect the electrical properties of the printed circuit, resulting in electrical failure; while PU (Poly Urethane) leather is a thermosetting material, which is inconvenient for subsequent processing. This application uses TPO leather as the base material because TPO not only has higher strength but also has heat plasticity without a base cloth. Drawing on the INS diaphragm vacuum forming process, the printed TPO skin and the plastic skeleton are cleverly integrated, thereby avoiding the problem of circuit structure positioning failure caused by processes such as manual coating and IMG (In Mold Graining).

[0039] The surface of the leather layer clearly marks the button area. The button area is typically identified by a pattern representing the corresponding button function. This identification pattern can be a color different from the leather layer or a translucent pattern. The identification pattern can be attached to the outer surface of the leather layer or the inner surface of the leather layer, and this application is not limited to this.

[0040] Conductive circuits are used to transmit voltage or touch signals corresponding to the key areas. These circuits can be made using flexible printed circuits (FPCs) or by printing a metallized pattern directly on the inner surface of the leather layer. To ensure strong adhesion between the printed conductive circuits and the leather layer, the leather layer must be surface treated with a high-elongation conductive ink to facilitate the subsequent blister molding process and ensure performance reliability.

[0041] Optionally, the leather layer with a clean surface and no oil or impurities is subjected to a denier treatment to improve the surface state of the TPO leather, provide a good surface for the printing of the conductive circuit, and improve the printing quality and the stability of the conductive circuit.

[0042] Schematically, plasma treatment atmosphere: TPO is treated with a mixed atmosphere of nitrogen and helium. Nitrogen can nitride the surface to a certain extent, enhancing its surface activity and slightly increasing its surface hardness; helium has good penetrability, which helps the plasma act evenly across the entire treatment area.

[0043] Optionally, the plasma treatment process parameters are: the treatment time is set to 6-9 minutes; the power is 120-180W; in terms of gas flow, the nitrogen flow is controlled at 8-15sccm, and the helium flow is 25-40sccm; the vacuum degree during treatment is maintained at 20-40Pa to ensure the uniformity and effectiveness of the plasma treatment.

[0044] The conductive circuits utilize conductive ink with silver nanoparticles as the primary conductive component, which exhibits excellent conductivity and stability. Polyurethane resin is also added as a binder to enhance the ink's adhesion and flexibility. Ethanol is used as a solvent to adjust the ink's viscosity and drying speed. The conductive ink used in this embodiment exhibits a high elongation of up to 200%. Furthermore, redundant circuit and film components are added during the printed circuit design to accommodate dimensional changes during the stretching process.

[0045] Preferably, before printing the conductive circuits, an adhesive is applied to improve adhesion. For example, a silane coupling agent is used: γ-aminopropyltriethoxysilane (KH-550) and isopropyl alcohol are mixed in a volume ratio of 1:5 to 1:10. The mixture is then sprayed onto the inner surface of the TPO leather and dried at a temperature between 80-120°C for 10-30 minutes.

[0046] When printing conductive lines, screen printing technology is usually used, with a screen mesh of 200-300 mesh. The printing speed is 12-18 mm / s and the pressure is 2.5-3.5 kg / cm 2 The printing thickness is 12-18μm. The printing environment temperature is controlled at 20-25℃ and the relative humidity is controlled at 40%-60%. After printing, it is dried in an oven at 80-90℃ for 15-30 minutes to ensure that the conductive circuit is completely dry and cured.

[0047] Touch capacitors generate electrical signals when pressure is applied. These signals indicate the area of the button that is pressed or touched.

[0048] The touch capacitor can use indium tin oxide (ITO) nanoparticle dispersion as the main material, adding a polymer binder such as polyvinyl alcohol or polymethyl methacrylate; the solvent can be acetone or isopropyl alcohol.

[0049] Preferably, 55% of indium tin oxide (ITO) nanoparticle dispersion, 15% of polyvinyl alcohol, and 30% of acetone are used.

[0050] Optionally, high-precision screen printing or inkjet printing is used for touch capacitor printing. Schematically, a screen with a mesh size of 400-500 is used, a printing speed of 5-10 mm / s, and a pressure of 1-2 kg / cm 2 , the printing thickness is 5-10μm; the touch capacitor is manufactured by screen printing under the conditions of ambient temperature of 20-25℃ and relative humidity of 40%-60%.

[0051] After printing, low-temperature curing is performed in an oven at 80-100°C. Optionally, the curing time is 15-25 minutes.

[0052] The insulating layer is used to shield the conductive circuit to prevent external electrical signals from interfering with the conductive circuit.

[0053] Alternatively, polyimide (PI) or polyester (PET) can be used as the base insulating ink, with appropriate inorganic fillers such as alumina and silica added to enhance insulation performance. Solvents such as butanone and cyclohexanone can be used. For example, the PET resin has a mass fraction of 45%, silica has a mass fraction of 25%, and butanone has a mass fraction of 30%.

[0054] The insulating layer is manufactured using screen printing technology. Schematically, the screen mesh size is 300-400 mesh. The printing speed is 8-15 mm / s and the pressure is 1.5-2.5 kg / cm 2 , the printing thickness is 20-30μm. The ambient temperature is controlled at 22-28℃, and the relative humidity is 45%-55%.

[0055] The conductive circuit 3 has a signal transmission line, and the electronic control device further includes a circuit board 7, which is arranged on a side of the insulating layer 5 away from the conductive circuit 3;

[0056] The signal transmission line (not shown in the figure) of the conductive circuit 3 is connected to the corresponding interface of the circuit board 7.

[0057] The circuit board is used to process the electrical signals transmitted by the conductive circuit, so that when the key area is activated, the corresponding function is triggered. Optionally, the circuit board is a printed circuit board (PCB) or a flexible circuit board (FPC), which is not limited in this application.

[0058] The conductive circuit and the circuit board transmit signals to corresponding ports of the circuit board via signal transmission lines for the circuit board to process the signals.

[0059] The electronic control device further comprises a packaging layer 8, which is at least partially attached to the circuit board 7. Figure 2 shown.

[0060] Preferably, the encapsulation layer uses MasterBond EP30CL epoxy resin, encapsulated by adhesive coating. Mix the epoxy resin base and curing agent in a weight ratio of 10:1. Stir with an electric stirrer until the mixture is uniform and free of bubbles. Typically, stir at 300-500 rpm for 3-5 minutes.

[0061] Place the prepared epoxy resin into the dispenser's barrel. Set the dispenser's dispensing speed to 0.5-1.0 ml / s and the dispensing pressure to 0.2-0.4 MPa. Apply the epoxy resin continuously and evenly to the printed circuit board, ensuring the encapsulation layer completely covers the circuitry and components. Keep the coating thickness within 2-2.5 mm.

[0062] The glued product was placed in a constant temperature oven at 80°C for 2 hours for curing.

[0063] By using a printing process to print conductive circuits on the leather layer, the structure of the vehicle interior is made compact, simple and lightweight.

[0064] like Figure 3 As shown, a prompt pattern is provided on the surface of the leather layer at a position corresponding to the key area 2;

[0065] The prompt pattern is used to identify the key function of the key area 2 corresponding thereto.

[0066] The reminder pattern is used to identify the function of the corresponding key area. The reminder pattern can be a pattern with a different color from the leather layer, or a translucent pattern. This clearly indicates the function of the corresponding key area.

[0067] Preferably, the prompt pattern is a light-transmitting pattern, and at least one group of light-emitting components 71 is provided on the circuit board at a position corresponding to the light-transmitting pattern;

[0068] The light emitted by the light-emitting component illuminates the light-transmitting pattern.

[0069] Preferably, the light-emitting component includes at least one LED lamp bead.

[0070] Use precision dispensing equipment to dispense glue at the desired locations on the printed conductive circuit. For example, use silver-based low-temperature conductive glue, and the dispensing locations should correspond to the positions of the LED pins and PCB pads.

[0071] Use high-precision placement equipment to accurately place the LED and PCB in the locations where the conductive adhesive is applied. During the placement process, ensure that the LED pins and PCB pads are in full contact with the conductive adhesive and that the orientation and position of the components are correct.

[0072] After placing the LED and PCB, apply appropriate pressure through the patch equipment. In this case, 0.5-1N is selected for 2-3 seconds to promote uniform distribution of the conductive adhesive and good contact.

[0073] Place the post-mount product in a heating and curing machine, set the curing temperature to 100-120°C and the curing time to 15-30 minutes. During the curing process, ensure uniform temperature distribution to avoid local overheating or overcooling. Also, avoid defects such as bubbles, missing glue, and uneven glue layers, and ensure good circuit connections.

[0074] The electronic control device further includes a light shielding layer 6, which is arranged between the circuit board 7 and the insulating layer 5;

[0075] The light shielding layer 6 is provided with a hollow pattern at a position corresponding to the light emitting component 71; the shape of the hollow pattern corresponds to the key area.

[0076] The leather layer after the above circuit printing, integrated components and packaging is subjected to blister forming. The process parameters are as follows: sheet heating temperature: 130-150°C; heating time: 30-50 seconds; vacuum degree: -0.07--0.09MPa; molding time: 15-25 seconds.

[0077] To minimize displacement and deformation of conductive printed circuits and light-emitting components during the blister stretching process, the following measures are taken to minimize this effect and ensure accuracy and performance: Before printing, pre-stretch the TPO leather to minimize deformation during the blister stretching process. Optionally, the pre-stretching value is between 5% and 15%. Preferably, the pre-stretching is 10%; optimize the design of the printed pattern and increase redundancy in the circuit and film to accommodate dimensional changes during the blister stretching process; when designing the blister mold, consider the tensile properties of the material, set positioning points and stretch compensation to ensure the positional accuracy of the printed circuit, touch film, and LED; use high-precision positioning fixtures and clamps to fix and position the TPO leather during the blister stretching process to reduce displacement; inspect and correct the blister-formed product to promptly detect and repair defects in the circuit and film caused by stretching.

[0078] Through the light-emitting component and the hollow pattern in the light-shielding layer, the emitted light is concentrated on the light-transmitting pattern, illuminating the light-transmitting pattern in the key area, making the pattern identification clear and easy to identify.

[0079] The electronic control device further includes a base 9 , which is bonded to the packaging layer 8 .

[0080] The packaging layer 8 is provided with a fixing portion 81 relative to the surface of the attached circuit board 7. Figure 4 As shown, the surface where the base 9 and the packaging layer 8 are joined is provided with a matching portion 91, as shown in FIG. Figure 5As shown, the position of the matching portion 91 corresponds to the position of the fixing portion 81 one to one.

[0081] It should be noted that the fixing portion and the matching portion adopt a concave-convex matching method, and the specific shapes of the fixing portion and the matching portion, and the number of the fixing portion and the matching portion are not limited to Figure 4 、 Figure 5 Any shape that satisfies the concave-convex fit and any reasonably set number can be used as the fixing portion and the fitting portion.

[0085] Mould parameters: Mould temperature: 40-80℃.

[0086] Screw parameters: screw speed: 30-70rpm; screw back pressure: 5-15MPa.
