Description

Technical Field

[0001] The present disclosure relates to the technical field of smart surfaces, and in particular to a smart surface structure, an electronic device, a seat controller, a window controller, and a vehicle. Background Art

[0002] IME (In-Mold-Electronics) is a process that directly integrates patterns, conductive circuits, and electronic components such as LED lights, resistors, capacitors, and touch electrodes into injection-molded products during the injection molding process. This intelligent surface technology, which displays specific patterns and realizes certain functions, is widely used in automobiles, home appliances, medical devices, portable electronic devices, aviation, and other fields.

[0003] In related technologies, pattern layers, electronic components, circuits, etc. are concentrated on the same film layer. The distance between the LED lamp and the pattern surface is relatively close, and light guiding treatment cannot be performed, resulting in uneven light guiding and light channeling problems in the product. In order to increase the strength of the pattern layer, the number of overprintings needs to be increased, and the same film layer needs to be repeatedly printed and injection molded, resulting in a high scrap rate. The hardness of components and circuit ink affects the tension, causing damage to the pattern layer. Due to the printing of conductive silver paste and the mounting of electronic components on the film, the film is heated unevenly, resulting in local shrinkage of the product surface. Electronic components such as LED lamp beads are easily offset during the injection molding process. Utility Model Content

DETAILED DESCRIPTION

[0058] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0059] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, top, and bottom" are generally defined when the smart surface structure provided by the present disclosure is normally installed. Figure 1 and Figure 16 In the drawing orientation, "inside" and "outside" may refer to the inside and outside of the corresponding component's outline, or its location inside or outside the surrounding environment, depending on the specific context. Furthermore, when the following description refers to the accompanying drawings, unless otherwise indicated, identical numerals in different drawings represent identical or similar elements. The terms "first," "second," and the like, as used in this disclosure, are intended to distinguish one element from another and do not connote sequential order or importance.

[0060] Taking the application of intelligent surface structures in the automotive sector as an example, car interiors are constantly evolving towards entertainment and comfort, with large screens, lighting, and touch buttons everywhere. While this brings convenience, it also creates drawbacks such as an increasing number of control factors, a lack of design, a lack of cohesiveness, and distraction. IME technology, with its highly integrated invisible backlight and concealed touch buttons on surfaces of various materials, not only meets interactive needs but can be readily hidden, reducing driver distraction and improving safety. It also creates a cohesive and design-focused design by integrating structural components with circuitry, resulting in lightweight and efficient space utilization.

[0061] In this disclosure, Figures 2 to 18 As shown, the present disclosure provides a smart surface structure, which includes a decorative layer 2, a substrate layer 1 and a functional layer 3 arranged in a stacked manner. The present disclosure provides different embodiments of the smart surface structure. Before introducing multiple embodiments, the decorative layer 2, the substrate layer 1 and the functional layer 3 are introduced in detail.

[0062] Regarding substrate layer 1, materials with good light transmittance are generally selected, such as PC (polycarbonate), PMMA (polymethyl methacrylate), acrylic acid, ABS (acrylonitrile-butadiene-styrene copolymer), AES (sodium fatty alcohol polyoxyethylene ether sulfate), PI (polyimide), and PPA (polyphthalamide). This ensures that light emitted by the light-emitting elements 311 of functional layer 3 can pass through substrate layer 1 and reach decorative layer 2. Substrate layer 1 can be formed during the injection molding process of decorative layer 2 or manufactured separately, both of which fall within the scope of protection of this disclosure.

[0063] Regarding the decorative layer 2, Figure 4 and Figure 15 As shown, the decorative layer 2 is provided with an information mark 20. Figure 4 In the seat controller embodiment shown, the information mark 20 includes the position adjustment of the headrest, backrest and seat cushion, and also includes the adjustment of the seat working mode, H represents the heating mode, V represents the ventilation mode, and M represents the massage mode. Figure 15 In the embodiment of the sunroof controller shown, the information mark 20 includes the light-emitting position of two reading lights and the control and emergency help mark of the sunroof. Of course, the above information mark 20 is not limited to the content provided in the embodiment and can be designed as needed.

[0064] The above-mentioned information mark 20 has an off state and an awake state. In the off state, the information mark 20 is not displayed, and the outer surface of the decorative layer 2 is consistent with the surface to be installed of the intelligent surface mounting structure, and is integrated with the surrounding interior, achieving a hidden effect, a more integrated shape, and will not distract the driver's attention, making it safer and more reliable. When the driver needs it, he can touch the information mark 20 lightly to switch to the awake state. The information mark 20 is displayed, and touching the information mark 20 can trigger a preset action. The preset action here is executed by the driving component inside the seat or sunroof, which can be an action to drive the seat back to adjust forward or backward, or it can be executed by the heater, which can be an action to heat the backrest, etc., without specific restrictions. Just press and hold the corresponding information mark 20 with your finger. The information mark 20 will respond to the pressure and make corresponding actions and feedback, so that the seat and sunroof can be adjusted. By pressing and holding the circle positions on both sides of the sunroof controller, the brightness of the reading light will change, which can be adjusted according to user needs. In addition, only the information mark of the reading light can be displayed in the sunroof controller. The information mark of the sunroof adjustment will be turned off within the set time. When the reading light function is not needed, double-click the information mark of the reading light to turn off the reading light. The interactive method of the information mark 20 can be designed differently according to needs.

[0065] exist Figure 5 、 Figure 7 and Figure 10 In the illustrated embodiment, the decorative layer 2 has an inner surface and an outer surface, with the information mark 20 disposed on the inner surface. To achieve a better concealment effect, the outer surface of the decorative layer 2 can be printed with a texture consistent with the surface to be mounted on the smart surface structure, or covered with translucent fabric, leather, or the like. The information mark 20 can be concealed beneath the translucent texture or fabric. Of course, the outer surface of the decorative layer 2 can also have the same material, pattern, and design as the surface to be mounted on the smart surface structure to enhance overall consistency.

[0066] The information mark 20 on the inner surface of the decorative layer 2 is printed with a light-transmitting ink, while the remaining areas of the inner surface, excluding the information mark, are printed with a light-blocking ink. This allows the light-emitting element 311 in the functional layer 3 to see through the information mark 20, displaying it, hiding the backlight, or functioning as a reading light. The remaining areas of the decorative layer 2, excluding the information mark 20, are printed with a light-blocking ink to prevent light from the light-emitting element 311 from passing through other areas, ensuring a smooth overall viewing experience and ensuring passenger comfort.

[0067] Regarding the functional layer 3, it is equipped with a light-emitting element 311, which can be an LED. Multiple light-emitting elements 311 can be provided, corresponding to the positions of the information indicia 20 on the decorative layer 2. These elements provide backlighting, illuminating and displaying the information indicia 20. This helps the light-emitting elements 311 illuminate and evenly illuminate the information indicia 20. The position, number, and arrangement of the light-emitting elements 311 can be designed based on the number and location of the information indicia 20. To detect touch, the functional layer 3 is equipped with a touch sensor element 314 to detect pressure applied to the surface. The functional layer 3 may also include a capacitor element 315, an inductor element, silver paste circuitry 316, a sensor chip, etc. The capacitor element 315 can correspond to the position of the information indicia 20 on the decorative layer 2, effectively identifying and monitoring the location of the user's press. When the information indicia 20 triggers an action, such as adjusting the seat back forward, a vibration element 313, such as a vibration motor, is provided in the functional layer 3 to provide feedback through vibration, alerting the user that the action has been performed. In other embodiments, feedback may also be provided by flashing the information mark 20 , and the specific form is not limited.

[0068] In existing IME technologies, such as Figure 1 As shown, integrating the decorative layer 2', electronic components, circuits, etc. (functional layer 3') into the same film layer (substrate layer 1') presents various issues discussed in the background technology section. To address these issues, in the smart surface structure provided herein, the decorative layer 2 and functional layer 3 are disposed on opposite surfaces of the substrate layer 1. Separately disposed and manufactured, the decorative layer 2 and functional layer 3 minimize impact on the decorative layer 2, lowering scrap rates and directly reducing the number of printing processes per film sheet, thereby lowering costs. By adjusting the thickness of the substrate layer 1, the light-emitting element 311 in the functional layer 3 can be moved away from the decorative layer 2. This increases the distance between the light-emitting element 311 and the decorative layer 2, allowing for light-guiding processing and avoiding light crosstalk. The structure will be described in detail below, in conjunction with various embodiments.

[0069] In one exemplary embodiment of the present disclosure, the decorative layer 2 and substrate layer 1 can be formed into a single piece, with the functional layer 3 separately affixed to the surface of the substrate layer 1 facing away from the decorative layer 2. The decorative layer 2 can be injection-molded with the substrate layer 1 before the functional layer 3 is affixed to the bottom of the substrate layer 1, forming a complete structure. The functional layer 3 is not involved in the injection molding process, preventing electronic components such as the light-emitting element 311 in the functional layer 3 from being displaced or damaged during the molding process. The outer surfaces of the substrate layer 1 and decorative layer 2 after injection molding are unaffected by the electronic components in the functional layer 3, preventing embossing of circuits or component pins. The resulting surfaces exhibit excellent flatness, receive more even heat, and avoid surface shrinkage.

[0070] It should be noted that this intelligent surface structure can be applied to fields such as automobiles, household appliances, portable electronic devices, and aviation. When applied to automobiles, it can be used for interior surface structures such as intelligent central control displays, seat controls, air conditioning controls, sunroof controls, steering wheel sensors, door handle lighting control, seat belt fabric surface controls, and intelligent displays on the instrument panel, all of which fall within the scope of protection of this disclosure. The substrate layer 1 and decorative layer 2 can be formed into a single piece through in-mold injection molding. Alternatively, the decorative layer 2 can be transferred to the substrate layer 1 using in-mold transfer technology or affixed to the surface of the substrate layer 1 by gluing. The functional layer 3 can be affixed to the surface of the substrate layer 1 by gluing, welding, or microstructuring.

[0071] Taking the seat controller as an example, in an exemplary embodiment of the present disclosure, Figures 2 to 8 As shown, the functional layer 3 includes a circuit board 31, and the substrate layer 1 has a first surface 11 for fixing the decorative layer 2 and a second surface 12 for fixing the functional layer 3, as shown in FIG. Figure 6 and Figure 8 As shown, the second surface 12 is provided with a retaining structure 122 for positioning the circuit board 31. The retaining structure 122 can be a positioning post provided on the second surface 12, and the circuit board 31 is provided with a positioning hole that cooperates with the positioning post. There can be two retaining structures 122, arranged at diagonally opposite positions. In other embodiments, the retaining structure 122 can also be a stopper, a latching protrusion, etc.

[0072] In another exemplary embodiment of the seat controller, as Figure 5 As shown, the functional layer 3 further includes a membrane 37 disposed on the second surface 12 of the substrate layer 1. The membrane 37 is provided with a touch sensor element 314. The circuit board 31 can be connected to the membrane 37 via a connector 312 to be fixed to the second surface 12 of the substrate layer 1. The membrane 37 is provided with the touch sensor element 314 and can be adhesively fixed to the second surface 12. The second surface 12 of the substrate layer 1 is provided with a receiving groove 121. The touch sensor element 314 is located within the receiving groove 121. This allows the touch sensor element 314 to adhere to the substrate layer 1, preventing it from protruding from the second surface 12 of the substrate layer 1. The touch sensor element 314 is closer to the decorative layer 2, making it easier to receive user touch signals, thereby monitoring changes in surface pressure on the decorative layer 2 and achieving the corresponding function. The number of touch sensor elements 314 can be selected as needed.

[0073] exist Figure 7 In the embodiment shown, the touch sensing element 314 is directly disposed on the circuit board 31, and the connector 312 can be omitted. Figure 8As shown, a contact post 124 is provided on the second surface 12 of the substrate layer 1 to abut against the touch sensing element 314. The pressure of the user pressing the information mark 20 can be transmitted to the touch sensing element 314 through the contact post 124 for signal transmission, thereby monitoring the user's intention.

[0074] In order to fix the vibration element 313, a mounting groove 123 is provided on the second surface 12 of the substrate layer 1, and a vibration element 313 is provided on the circuit board 31, and the vibration element 313 is installed in the mounting groove 123. Figure 5 In the illustrated embodiment, the diaphragm 37 is provided with a positioning hole 371 for the limiting structure 122 to pass through and an opening 372 for avoiding the vibration element 313 , which will not affect the positioning installation of the circuit board 31 and the installation of the vibration element 313 .

[0075] Connector 312 can be positioned at the edge of circuit board 31 to connect to diaphragm 37. Connector 312 can be a flexible component that transmits signals from touch sensor 314 to circuit board 31, and then to the vehicle controller for controlling the seats, sunroof, and other components. The aforementioned light-emitting element 311 and capacitor 315 can also be positioned on circuit board 31.

[0076] exist Figure 5 In the embodiment of the seat controller shown, the decorative layer 2 and the substrate layer 1 are first formed into an integral part by in-film injection molding, transfer printing or lamination, and then the diaphragm 37 with the touch sensor element 314 is laminated on the second surface 12 of the substrate layer 1. During the lamination process, the touch sensor element 314 is placed in the receiving groove 121, and then the vibration element 313 is placed in the installation groove 123. Finally, the circuit board 31 is connected to the diaphragm 37 through the connecting member 312, and the circuit board 31 is limited and fixed by the limiting structure 122 to complete the assembly of the smart surface structure.

[0077] In another exemplary embodiment of the present disclosure, Figures 9 to 15 As shown, a smart surface structure is provided. The smart surface structure includes a substrate layer 1 and a decorative layer 2 and a functional layer 3 disposed on opposite surfaces of the substrate layer 1. The decorative layer 2, substrate layer 1, and functional layer 3 form an integrated structure. The decorative layer 2 and functional layer 3 can be placed on the front and rear molds of an injection mold, respectively, and low-pressure injection molding is performed between the front and rear molds to form the integrated structure.

[0078] The decorative layer 2 and functional layer 3 are positioned on either side of the substrate layer 1, effectively increasing the light-guiding distance of the light-emitting elements 311 in the functional layer 3. This allows light to be more evenly distributed on the decorative layer 2, resulting in a more uniform and clear brightness for the information markings 20 on the decorative layer 2. The three layers are designed as an integrated structure, effectively ensuring the components' waterproof and dustproof properties, improving oxidation resistance, and preventing the problem of loose fixation after oxidation. This reduces assembly steps and improves efficiency. The use of low-pressure injection molding technology effectively reduces the impact of the substrate layer 1 on the electronic components 30 in the functional layer 3 during the molding process, thereby improving the yield rate of the finished product.

[0079] In this embodiment, taking the sunroof controller as an example, Figure 12 As shown, the functional layer 3 has an electronic component 30 and a packaging portion 32 for covering the electronic component 30. The electronic component 30 can be at least one of the light-emitting element 311, capacitor element 315, resistor element, inductor element, touch sensor element 314, sensor chip, and silver paste circuit 316 introduced above. In order to avoid the base material from impacting the electronic component 30 in the functional layer 3 during the one-piece injection molding process, causing the electronic component 30 to have the risk of being deflected, the electronic component 30 in the functional layer 3 is first packaged before injection molding. Low-pressure injection molding or liquid silicone molding can be used to package the electronic component 30 to avoid damage to the electronic component during the subsequent injection molding process. Since the amount of base material used in the packaging process is significantly less than the amount of base material used in the three-in-one injection molding process, the early packaging process can effectively reduce damage to the electronic component 30.

[0080] The light emitting element 311, the capacitor element 315, the sensor chip and the silver paste circuit 316 are designed in the functional layer 3, which can reduce the layout area of ​​the circuit board and the use of the electronic components 30, thereby reducing the weight of the parts. There is no restriction on the position and number of the multiple electronic components 30 in the functional layer 3. Figure 13 As shown, the functional layer 3 has a capacitor element 315. There can be multiple capacitor elements 315 and they correspond to the positions of the information marks 20 of the decorative layer 2. The multiple capacitor elements 315 can be arranged in a matrix, and a capacitor element 315 is provided between two adjacent light-emitting elements 311. Light-emitting elements 311 and capacitor elements 315 are provided on both sides of the touch sensing element 314. The specific arrangement and design can be carried out according to needs.

[0081] like Figure 12 As shown, the second surface 12 of the substrate layer 1, which faces the functional layer 3, is provided with a groove 10 for accommodating the encapsulation portion 32, thereby ensuring the integrity of the smart surface structure. The encapsulation portion 32 protrudes from the surface of the functional layer 3. During the integral injection molding process, the groove 10 structure is automatically formed on the second surface 12 of the substrate layer 1, ensuring the integrity of the structure.

[0082] Functional layer 3 has a mounting hole 35 for mounting a vibration element 313. Mounting seat 36 is provided within mounting hole 35, and vibration element 313 can be secured to mounting seat 36. During integral injection molding, the mounting position of vibration element 313 can be avoided by reserving mounting hole 35 and providing mounting seat 36 within mounting hole 35. Vibration element 313 can then be directly secured to mounting seat 36.

[0083] exist Figures 9 to 11 In the embodiment shown, the plurality of electronic components 30 in the functional layer 3 are first packaged to form Figure 13 The functional layer 3 is shown, and then the decorative layer 2 and the functional layer 3 are placed on the front and rear molds of the injection mold, and low-pressure injection molding is performed between the front and rear molds to form an integrated structure. Finally, the vibration element 313 is installed to complete the molding process of the smart surface structure.

[0084] In the above embodiment, the decorative layer 2 and the functional layer 3 may be separate patch layers. Figure 16 and Figure 17 As shown, a smart surface structure is provided. The smart surface structure includes a decorative layer 2, a substrate layer 1, and a functional layer 3, which are sequentially stacked. The decorative layer 2 includes a first film 21 and a pattern layer 22 fixedly connected to the first film 21. The functional layer 3 includes a second film 33 and an electronic component layer 34 fixed to the second film 33. The pattern layer 22 can be printed on the first film 21, formed into the desired shape through heating, pressurization, and vacuum adsorption, and then cut to form the decorative layer 2. The electronic component layer 34 can be a film layer having multiple electronic components 30 and is fixed to the second film 33 through processes such as solder paste printing, chip mounting, and soldering to form the functional layer 3. The first diaphragm 21 and the second diaphragm 33 can be PMMA+PC diaphragms, PET diaphragms or PPA diaphragms, etc. Here, the pattern layer 22 can be understood as the inner surface of the decorative layer 2 introduced above, and the information mark 20 is set on the pattern layer 22. The information mark 20 is formed by printing with light-transmitting ink, and light-shielding ink is printed at other positions. The first diaphragm 21 can be the outer surface of the decorative layer 2, and the outer surface is coated with a texture or fabric consistent with the surface to be installed on the smart surface structure. The electronic component 30 can also be at least one of the light-emitting element 311, capacitor element 315, resistor element, inductor element, touch sensor element 314, sensor chip, and silver paste circuit 316 introduced above, which will not be repeated here.
