[0096] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0097] This application discloses a hidden interior structure that is applied to the interior of a vehicle. The hidden interior structure is a controller with certain control functions, and its appearance can create a comfortable, beautiful, and intelligent in-vehicle environment for the user.

[0098] Reference Figures 1-30 As shown, the hidden interior structure includes a pattern layer 10, a substrate layer 20, and a functional layer 30. The pattern layer 10 and the substrate layer 20 are an integral structural component, and the pattern layer 10, the substrate layer 20, and the functional layer 30 are stacked sequentially. The functional layer 30 is provided with a circuit 38 for realizing control functions.

[0099] The pattern layer 10 is the outermost layer of the hidden interior structure, and it is used to display the appearance of the hidden interior structure. The pattern layer 10 is provided with a beacon pattern 15, through which the control function corresponding to the beacon pattern 15 can be obtained, so as to facilitate the user to operate and control it.

[0100] The substrate layer 20 is used to support and connect the pattern layer 10 and the functional layer 30, and the substrate layer 20 enables the hidden interior structure to have a stable and reliable structure.

[0101] The functional layer 30 is provided with a circuit 38, which includes electronic components 39 and wires 35. The circuit 38 enables the functional layer 30 to implement the control function of the hidden interior structure.

[0102] The concealed interior structure of this application embodiment includes a pattern layer 10, a substrate layer 20, and a functional layer 30 stacked sequentially. This concealed interior structure has the advantage of simple structure. The concealed interior structure can realize control functions through circuits 38 disposed on the functional layer 30. Compared to setting circuits 38 on a printed circuit board assembly (PCBA), this further reduces structural complexity, making the concealed interior structure even simpler. Moreover, the pattern layer 10 and the substrate layer 20 are an integral structural component, effectively ensuring the reliable connection between them, enhancing the waterproof and dustproof function of the concealed interior structure, and avoiding the phenomenon of weak adhesion due to oxidation when using adhesive bonding.

[0103] In some embodiments, the pattern layer 10, the substrate layer 20, and the functional layer 30 are an integral structural component. In the above-described structure of this application embodiment, the integral structural component enhances the dust and water resistance of the concealed interior structure, improves its oxidation resistance, and prevents the pattern layer 10, substrate layer 20, and functional layer 30 from being loosely connected; it also reduces the installation process of components within the concealed interior structure, improving assembly efficiency.

[0104] In some embodiments, a functional layer 30 is formed by inserting a piece into the pattern layer 10 and the substrate layer 20 through low-pressure injection molding or potting, so that the pattern layer 10, the substrate layer 20 and the functional layer 30 are an integral structural component.

[0105] Low-pressure injection molding is an encapsulation process that injects encapsulation material into a mold at very low injection pressure (e.g., 1.5 bar - 40 bar) and rapidly cures it (curing time, e.g., 5 seconds - 50 seconds). It is a process between potting and high-pressure injection molding. Compared to other potting processes, low-pressure injection molding offers advantages such as improved end-product performance, extremely low injection pressure, no damage to electronic components 39, low temperature, and low defect rate. It also provides excellent packaging protection, such as sealing, waterproofing, moisture resistance, shock absorption, insulation, and flame retardancy. In this embodiment, low-pressure injection molding is performed between the pattern layer 10 and the substrate layer 20 to form the functional layer 30, which can effectively reduce the defect rate of the hidden interior structure and give the hidden interior structure the aforementioned advantages.

[0106] In some embodiments, the surface of the substrate layer 20 facing away from the pattern layer 10 is connected to the functional layer 30.

[0107] In some embodiments, a pattern layer 10 is printed on one side of the substrate layer 20 so that the pattern layer 10 and the substrate layer 20 are an integral structural component.

[0108] In some embodiments, the pattern layer 10 is injection molded or potted to form a substrate layer 20 on the surface of the functional layer 30, so that the pattern layer 10 and the substrate layer 20 are an integral structural component.

[0109] In other embodiments, one side of the substrate layer 20 is covered with the pattern layer 10, and the other side of the substrate layer 20 is connected to the functional layer 30, so that the pattern layer 10, the substrate layer 20 and the functional layer 30 are connected to form a single component.

[0110] In some embodiments, the circuit 38 includes a light source device 31, and the pattern layer 10 is provided with a light-transmitting beacon pattern 15; the light source device 31 is set corresponding to the beacon pattern 15; when the light source device 31 emits light, the beacon pattern 15 is displayed; when the light source device 31 is turned off, the beacon pattern 15 is hidden.

[0111] The light source device 31 is used to emit light. In this embodiment, the light source device 31 is not specifically limited. For example, the light source device 31 is an LED lamp with high energy efficiency and long life.

[0112] The beacon pattern 15 corresponds to the touch button 32 in the hidden interior structure. Pressing the beacon pattern 15 can realize the control function of the touch button 32 corresponding to the beacon pattern 15.

[0113] In this embodiment, the beacon pattern 15 is light-transmitting, allowing the light emitted by the light source device 31 to pass through the beacon pattern 15. The light source device 31 is positioned corresponding to the beacon pattern 15, which makes it easier for the light from the light source device 31 to illuminate the beacon pattern 15, resulting in brighter and more uniform light intensity emitted from the beacon pattern 15.

[0114] In the hidden interior structure of this application embodiment, when the light source device 31 is lit, the beacon pattern 15 is displayed; when the light source device 31 is turned off, the beacon pattern 15 is hidden. That is, the hidden interior structure can hide the beacon pattern 15 when not in use, and the hidden interior structure is integrated with the interior, effectively realizing the integration of the vehicle interior.

[0115] The functional layer 30 of the hidden interior structure is provided with a light source device 31. The light emitted by the light source device 31 passes through the substrate layer 20 and the pattern layer 10 in sequence and is emitted out. The substrate layer 20 increases the light guiding distance of the light source device 31, which can make the light more evenly distributed on the pattern layer 10, and make the beacon pattern 15 presented on the pattern layer 10 clearer and more uniform in brightness.

[0116] In some embodiments, circuit 38 includes wires 35, a light source device 31, and an auxiliary control element, with wires 35 connected to the light source device 31 and the auxiliary control element respectively. In the above structure of this application embodiment, functional layer 30 has a light source device 31 and an auxiliary control element as electronic components 39, and wires 35 connecting the electronic components 39. Functional layer 30 has the function of a printed circuit board, and the hidden interior structure can realize the control function through circuit 38, making the structure of the hidden interior structure relatively simple.

[0117] In some embodiments, the functional layer 30 is provided with a conductor 35 formed by printing conductive ink or conductive silver paste as a conductive line, and a light source device 31 and an auxiliary control element are disposed at corresponding positions on the functional layer 30, and the light source device 31 and the auxiliary control element are connected to the conductor 35.

[0118] In some embodiments, in order to improve the stability of signal transmission in circuit 38 in functional layer 30, shielding lines can also be provided in functional layer 30.

[0119] In some embodiments, the auxiliary control element is configured according to the function of the hidden interior structure. For example, the auxiliary control element includes at least one of a resistor, a capacitor, a touch button 32, an inductor, and a pressure sensor 33.

[0120] In this embodiment, the functional layer 30 is provided with a circuit 38 for implementing control functions. The circuit 38 includes wires 35, light source devices 31, and auxiliary control elements. The auxiliary control elements include at least one of resistors, capacitors, touch buttons 32, inductors, and pressure sensors 33, as well as other actuators. In this case, the functional layer 30 can at least partially replace the printed circuit board, or reduce the layout area of ​​the printed circuit board and the amount of electronic components 39 used for the functions implemented by the functional layer 30, thereby making the printed circuit board lighter.

[0121] In some embodiments, the functional layer 30 is provided with an encapsulating plastic material 34, which encapsulates at least the light source device 31 and the auxiliary control element onto the functional layer 30 to avoid damage to the light source device 31 and the auxiliary control element on the functional layer 30 during the manufacturing process of the concealed interior structure. For example, it avoids the risk of the base material impacting the light source device 31 and the auxiliary control element during the integral injection molding of the functional layer 30 and the substrate layer 20, which could lead to misalignment or damage to the light source device 31 and the auxiliary control element, thereby improving the production yield of the concealed interior structure.

[0122] In some embodiments, refer to Figure 6 and Figure 9 As shown, a first mounting groove 21 is provided on the surface of the substrate layer 20 facing the functional layer 30; the light source device 31 protrudes from the surface of the functional layer 30, and the portion of the light source device 31 protruding from the functional layer 30 is placed within the first mounting groove 21. In the above structure of this embodiment, the portion of the light source device 31 protruding from the functional layer 30 is placed within the first mounting groove 21. The first mounting groove 21 can provide mounting space and protection for the light source device 31, and at the same time, it can ensure that the functional layer 30 can be completely attached to the substrate layer 20, realizing the stacked arrangement of the functional layer 30 and the substrate layer 20.

[0123] In some embodiments, the auxiliary control element protrudes from the surface of the functional layer 30, and the portion of the auxiliary control element protruding from the functional layer 30 is also placed in the first mounting groove 21.

[0124] In some embodiments, the substrate layer 20 is provided with a light-concentrating structure, which is used to concentrate the light from the light source device 31 onto the beacon pattern 15. In this embodiment, the light-concentrating structure can concentrate the light from the light source device 31 onto the beacon pattern 15, making the beacon pattern 15 clearer and more uniform in brightness.

[0125] In some embodiments, the light-concentrating structure is the first mounting slot 21. In this case, no additional light-concentrating structure is needed in the hidden interior structure, and the structure of the hidden interior structure is simpler.

[0126] In some embodiments, refer to Figure 24 As shown, the first mounting groove 21 forms a triangular truncated pyramid structure, and the inner wall of the first mounting groove 21 forms the top surface, bottom surface and two side surfaces of the triangular truncated pyramid structure. The opening of the first mounting groove 21 is another side surface of the triangular truncated pyramid structure; or, the first mounting groove 21 is an arc-shaped groove.

[0127] Part of the light source device 31 is inserted into the first mounting groove 21 through the opening of the first mounting groove 21. The first mounting groove 21 can focus light through the top surface, bottom surface and two side surfaces of the triangular truncated pyramid structure formed by the inner wall of the groove, so that the light from the light source device 31 is focused on the corresponding beacon pattern 15, making the beacon pattern 15 clearer and more uniform in brightness.

[0128] In this structure, the light source device 31 emits light from the top and outputs light from the top, which is emitted sequentially through the substrate layer 20 and the beacon pattern 15.

[0129] In some embodiments, the first mounting groove 21 is an arc-shaped groove. The arc-shaped groove can concentrate light, and the light source device 31 emits light from the top and outputs light from the top, passing through the substrate layer 20 and the beacon pattern 15 in sequence, so that the light from the light source device 31 is concentrated on the corresponding beacon pattern 15, making the brightness of the beacon pattern 15 clearer and more uniform.

[0130] In some embodiments, refer to Figure 26 As shown, the sidewall of the first mounting groove 21 away from the beacon pattern 15 is an arc-shaped surface 27, which protrudes away from the beacon pattern 15; the light-focusing structure is an arc-shaped surface 27.

[0131] In this structure, the light source device 31 also emits light from the side and outputs it from the top, passing sequentially through the substrate layer 20 and the beacon pattern 15. Further reference... Figure 7 It shows a schematic diagram of the structure of the light source device 31, which is a side-emitting device.

[0132] In some embodiments, a light-shielding strip 25 is provided within the substrate layer 20, and the light-shielding strip 25 can be referred to as Figure 5As shown, the light-shielding strip 25 divides the substrate layer 20 into multiple regions, each region corresponding to at least one beacon pattern 15 and a light-emitting device 31 corresponding to that beacon pattern 15. In the above embodiments of this application, the beacon pattern 15 and its corresponding light-emitting device 31 are located in the same region and are arranged in a one-to-one correspondence. The light emitted by the light-emitting device 31 is emitted from its corresponding beacon pattern 15, and due to the blocking effect of the light-shielding strip 25, it will not be emitted from other beacon patterns 15, effectively blocking light and preventing light from propagating on the substrate layer 20, thus avoiding light confusion.

[0133] In some embodiments, when multiple light-emitting devices 31 emit light of multiple colors, the light-shielding strip 25 can effectively prevent light leakage from affecting the consistency of the display colors of the beacon pattern 15, and effectively shield and block light from propagating on the substrate layer 20.

[0134] In some embodiments, some of the light source devices 31 can be used as reading lights. Since reading lights need to have relatively strong brightness, the light-shielding strip 25 can effectively block the light from the reading light from propagating on the substrate layer 20, thus preventing the strong light from the reading light from interfering with other beacon patterns 15.

[0135] In some embodiments, refer to Figure 2 and Figure 6 As shown, a beacon pattern 15 in any area can be set with at least two light source devices 31, thereby making the brightness of the beacon pattern 15 clearer and more uniform.

[0136] In some embodiments, refer to Figure 5 and Figure 6 As shown, a second mounting groove 22 is provided on the surface of the substrate layer 20 facing the functional layer 30, and a light-shielding strip 25 is disposed within the second mounting groove 22. The above-described structure of this embodiment has the advantage of simple structure. Moreover, the substrate layer 20 and the light-shielding strip 25 are independent components, and the light-shielding strip 25 will not affect the injection molding or potting molding of the substrate layer 20.

[0137] In some embodiments, the light-shielding strip 25 is placed into the second mounting groove 22 by means of applying glue or mounting, and then the functional layer 30 and the pattern layer 10 are connected. For example, glue is applied to the side of the functional layer 30 facing the pattern layer 10 to firmly attach the functional layer 30 to the substrate layer 20.

[0138] In some embodiments, the circuit 38 includes an electronic component 39 and an encapsulation plastic material 34 for fixing the electronic component 39 onto the functional layer 30. The electronic component 39 is surrounded by a dam 341, and the encapsulation plastic material 34 fills the outside of the dam 341 and is divided into a light-transmitting area 342 and a light-blocking area 343.

[0139] In this embodiment, the electronic component 39 can be any electronic component in the functional layer 30 described above, such as a light source device 31, resistor, capacitor, touch button 32, inductor, pressure sensor 33, etc., or any suitable component to be packaged and pre-fixed on the diaphragm. The electronic component 39 can be pre-welded and fixed on the diaphragm.

[0140] A dam 341 is constructed around the electronic component 39. Before encapsulation, a ring of damming adhesive is applied around the electronic component 39 to form the dam 341. This effectively protects the electronic component 39 within the dam 341 from the influence of the encapsulation plastic material 34 during encapsulation. This solves the problem of the electronic component 39 being prone to displacement and not being securely fixed.

[0141] During encapsulation, the film to be encapsulated can be placed into a first low-pressure injection mold. The low-pressure injection molding machine is started, and light-blocking low-pressure injection encapsulation plastic material is injected into the first low-pressure injection mold, filling it to the predetermined position. After the light-blocking plastic material cures in the mold, the film is removed. At this time, a light-blocking area 343 is formed on a portion of the film. Then, the film is placed into a second low-pressure injection mold, and the low-pressure injection molding machine is started, and light-transmitting low-pressure injection encapsulation plastic material is injected into the second low-pressure injection mold, filling it at least to the light-emitting surface of the light source device 31. The light-transmitting plastic material cures in the mold, and the film is removed. The film encapsulation is complete. Of course, the light-transmitting encapsulation plastic material can be injected first, followed by the light-blocking encapsulation plastic material. That is, the order in which the light-blocking area 343 and the light-transmitting area 342 are formed is not limited. In addition, the location and number of light-blocking areas 343 and light-transmitting areas 342 formed on the outer side of the dam 341 are not limited. They can be designed according to the shape of the dam 341 and the light guiding requirements. Taking the outer contour of the dam 341 as a rectangle as an example, any one or more sides can be filled with light-transmitting areas 342, and the remaining sides can be filled with light-blocking areas 343.

[0142] In this embodiment, the electronic component 39 can be pre-soldered and fixed onto the diaphragm using low-temperature solder paste or conductive adhesive, and then encapsulated and fixed using encapsulating plastic material 34. This provides reinforcement, preventing the electronic component from being displaced or detached during the final injection molding process of IME. Before encapsulation, a dam 341 is set around the electronic component 39 to prevent the encapsulating plastic material 34 from affecting the electronic component 39 within the dam 341. During encapsulation, light-blocking encapsulating plastic material and light-transmitting encapsulating plastic material are used separately to form a light-transmitting area 342 and a light-blocking area 343 at predetermined positions. This serves to guide and block light, solve the problem of light leakage, and ensure more uniform light output.

[0143] In some embodiments, the circuit 38 includes a plurality of light-emitting devices 31, which are fixed to the functional layer 30 by an encapsulating plastic material 34, and a light-blocking region 343 is formed between adjacent light-emitting devices 31 to prevent light leakage.

[0144] In some embodiments, the circuit 38 includes a non-light-emitting device 43, and at least the non-light-emitting device 43 is disposed in the light-blocking region 343.

[0145] That is, electronic components 39 may include light-emitting devices 31 and light-emitting devices 31. Light-emitting device 31 may be the resistor, capacitor, touch button 32, inductor, pressure sensor 33, etc., mentioned above. At least a light-transmitting area 342 is provided on the light-emitting surface of light-emitting device 31 to ensure that the emitted light from light-emitting device 31 can be emitted outward through the light-transmitting area 342. The light-blocking area 343 may fill the area around light-emitting device 31, the non-light-emitting surface of light-emitting device 31, and non-transparent positions. The light-transmitting area 342 may fill the light-emitting surface of light-emitting device 31 and other light-transmitting positions. Taking a square cross-section of light-emitting device 31 as an example... Figure 20 As shown, only one side can be a light-emitting surface, filled with a light-transmitting area 342, while the other three sides are filled with light-blocking areas 343. For example... Figure 21 and Figure 22 As shown, the light source device 31 is surrounded by a light-blocking area 343, and the surface of the light source device 31 opposite to the light-blocking area 343 is filled with a light-transmitting area 342. The first low-pressure injection mold and the second low-pressure injection mold can be designed according to the requirements of light transmission and light blocking, and the light-transmitting area 342 and the light-blocking area 343 are formed at the corresponding positions, respectively.

[0146] In some embodiments, the encapsulating plastic material includes a light-transmitting first encapsulating plastic material and an opaque second encapsulating plastic material. The light-blocking region 343 is formed by the second encapsulating plastic material, and the first encapsulating plastic material forms a light-transmitting region 342. At least the light-emitting surface of the light-emitting device 31 is provided with a light-transmitting region 342, and the non-light-emitting surface of the light-emitting device 31 is provided with a light-blocking region 343.

[0147] In some embodiments, the first encapsulation plastic material corresponding to the light-transmitting area 342 contains scattering particles. These scattering particles can improve the uniformity of light transmission, thereby enhancing the usability of the concealed interior structure.

[0148] In some embodiments, the encapsulating plastic material 34 can be made of materials such as polyamide (PA), polyolefin (PO), polyurethane (PU), and polycarbonate (PC). The encapsulating plastic material 34 corresponding to the light-transmitting area 342 contains scattering particles to form a light-transmitting low-pressure injection molding encapsulating plastic material. The encapsulation thickness of the encapsulating plastic material 34 can be 0.5-1.5 mm.

[0149] In some embodiments, such as Figure 21 As shown, the pattern units of the pattern layer 10 and the electronic components 39 of the functional layer 30 can be located on a first film 11. This smart surface structure includes the first film 11 and the pattern units, conductive lines, and electronic components 39 disposed on the first film 11. In this embodiment, the pattern units, conductive lines, and electronic components can be configured as separate pattern layers 10, conductive line layers 44, and electronic components and encapsulation plastic materials 45, respectively. The pattern layers 10, conductive line layers 44, and electronic components and encapsulation plastic materials 45 are sequentially stacked and located between the first film 11 and the substrate layer 20. The conductive line layer 44 may include conductive lines, touch electrodes, and pads. The conductive lines, touch electrodes, and pads of the pattern layer 10 and conductive line layer 44 can be printed on the first film 11. Electronic components 39 are soldered and fixed using conductive silver paste or low-temperature solder paste. The film after mounting is placed into a forming and punching machine for forming and punching to form the film to be packaged mentioned above. It is then placed into the first low-pressure injection mold and the second low-pressure injection mold in sequence. The low-pressure injection molding machine injects the low-pressure injection packaging plastic material into the mold and quickly solidifies it, forming a light-transmitting area 342 and a light-blocking area 343, thus reinforcing the electronic components 39, etc. Finally, the packaged film is placed into the inner cavity of the injection mold, and molten plastic material is injected into the mold to form the substrate layer 20, completing the IME product.

[0150] In other embodiments, such as Figure 22 As shown, the pattern layer 10 includes a first diaphragm 11 and pattern units disposed on the first diaphragm 11, and / or, the functional layer 30 includes a second diaphragm 37 and conductive lines and electronic components 39 disposed on the second diaphragm 37. In this embodiment, the pattern units are configured as separate pattern layers 10, which are located between the first diaphragm 11 and the substrate layer 20. The conductive lines and electronic components 39 are respectively configured as separate conductive line layers 44 and electronic components and encapsulating plastic materials 45, which are stacked sequentially and located between the substrate layer 20 and the second diaphragm 37. Pattern layer 10 can be printed on the first film 11, and then placed in a forming and punching machine for forming and punching to form pattern layer 10. Conductive circuit layer 44 is printed on the second film 37, and electronic components 39 are soldered using conductive silver paste or low-temperature solder paste. The film after mounting is placed in a forming and punching machine for forming and punching, and then sequentially placed into the cavities of the first and second low-pressure injection molds. A low-pressure injection molding machine is used to inject low-pressure injection encapsulation plastic material into the molds and rapidly solidify it to form functional layer 30. Finally, pattern layer 10 and functional layer 30 are placed into the cavity of the injection mold, and molten plastic material is injected into the mold to complete the IME product. About Figure 21 and Figure 22In the two embodiments, whether the pattern layer 10 and the functional layer 30 are single-layer patch layers or whether the pattern layer 10, electronic components and encapsulation plastic material 45 are separately set on the film, will not be elaborated further.

[0151] In some embodiments, a light-blocking region 343 is provided between the light-transmitting regions 342 of two adjacent light-emitting elements 311 in the functional layer 30, which can effectively solve the problem of light leakage. By arranging and adjusting the light-transmitting region 342 and the light-blocking region 343, a uniform light output effect can be achieved.

[0152] Low-pressure injection molding is used to encapsulate the diaphragm. This involves injecting the encapsulating plastic material into the mold at a very low injection pressure, typically 1.5-40 bar, and allowing it to solidify rapidly (5-50 seconds). Low-pressure injection molding is a process between potting and high-pressure injection molding. Compared to other potting processes, it improves the performance of the final product. The extremely low injection pressure prevents damage to components, and it offers advantages such as low temperature, low defect rate, and sealing, waterproofing, moisture resistance, shock absorption, insulation, and flame retardancy.

[0153] In some embodiments, the hidden interior structure further includes a light-guiding uniform layer 50, which is connected to the substrate layer 20 and is located between the substrate layer 20 and the functional layer 30.

[0154] In this embodiment, the light-guiding uniform layer 50 is used to guide light uniformly. The setting of the light-guiding uniform layer 50 can improve the light leakage problem of the hidden interior structure and increase the light guiding uniformity of the light source device 31.

[0155] In some embodiments, refer to Figure 27 As shown, the light guiding uniform layer 50 includes a first atomized PC film layer 51, a polarizing brightening film layer 53, and a second atomized PC film layer 52 stacked together, with the polarizing brightening film layer 53 disposed between the first atomized PC film layer 51 and the second atomized PC film layer 52.

[0156] The light-guiding uniform layer 50 of this embodiment includes a first atomized PC film layer 51 and a second atomized PC film layer 52 stacked together, and a polarizing brightening film layer 53 disposed on the first atomized PC film layer 51 and the second atomized PC film layer 52. The first atomized PC film layer 51 is located on the light-emitting side of the second atomized PC film layer 52.

[0157] In some embodiments, a fogging layer is provided on both the light-emitting side of the first fogging PC film layer 51 and the light-incident side of the second fogging PC film layer 52. The fogging layer includes convex hemispherical structures 54 of different sizes, with larger and smaller convex hemispherical structures 54 alternately distributed on the first and second fogging PC film layers 51 and 52. The aforementioned convex hemispherical structures 54 can be made into convex hemispherical particle size optical microstructures using a liquid optical resin with low refractive index, and then formed by UV curing. When light passes through the convex hemispherical structures 54, it will scatter to produce a fogging effect, making the light distribution more uniform. The surface of the convex hemispherical structures 54 has a preset roughness (for example, Ra0.8-2.0), forming a fogging effect to achieve optical haze.

[0158] In some embodiments, the light guiding uniform layer 50 may be a reflective polarizing brightness enhancement film, which can continuously repeat S-wave reflection and P-wave transmission to enhance brightness. The polarizing brightness enhancement film layer 53 is located between the LED lamp (the LED lamp is an example of the light source device 31) and the light focusing structure of the substrate layer 20. When light passes through the polarizing brightness enhancement film layer 53, P-polarized light can directly pass through the polarizing brightness enhancement film layer 53, while most of the S-polarized light is reflected back to the LED lamp by the polarizing brightness enhancement film layer 53. During the reflection process, the S-polarized light passes through the various layers of materials between the polarizing brightness enhancement film layer 53 and the LED lamp, thereby being depolarized and becoming fully polarized light (including P-polarized light and S-polarized light) before being emitted from the LED lamp again, thus being recycled to achieve the effect of increasing brightness.

[0159] In the hidden interior structure of this application embodiment, the light guiding uniform layer 50 utilizes the light-concentrating structure matching of the light guiding uniform layer 50 and the substrate layer 20 to achieve a high-gain brightness increase. At the same time, combined with the convex hemispherical structure 54 of different sizes on the surface of the first atomized PC film layer 51 and the second atomized PC film layer 52, light diffraction is generated to achieve atomization and diffusion effect, forming good light uniformity performance. This significantly improves the light penetration effect of LED light, enhances the surface display effect of the hidden interior structure, and makes the performance more stable, safe, and durable.

[0160] In some embodiments, the concealed interior structure further includes an operation feedback element electrically connected to the functional layer 30. The operation feedback element is used to provide feedback on the implementation of the control function. In this embodiment, when the control function is implemented through the concealed interior structure, the operation feedback element can provide feedback so that the user can perceive the implementation of the control function.

[0161] In some embodiments, the operation feedback element is at least one of the vibration motor 40 and the light source device 31 of the circuit 38.

[0162] Furthermore, when the operation feedback element is a vibration motor 40, the vibration motor 40 provides vibration feedback by vibrating. When the user triggers the touch button 32 hidden in the interior structure, the vibration motor 40 vibrates, indicating that the user has effectively triggered the touch button 32.

[0163] When the operation feedback element is the light source device 31 of circuit 38, the light source device 31 emits light or changes light or emits specific light for light feedback. When the user triggers the touch button 32 in the hidden interior structure, the light source device 31 emits light or changes light or emits specific light to indicate that the user has effectively triggered the touch button 32.

[0164] In some embodiments, the functional layer 30 is provided with a through hole 36; the side of the substrate layer 20 opposite to the pattern layer 10 is connected to the vibration motor 40, and the vibration motor 40 extends through the through hole 36. In the above structure of the hidden interior structure, the vibration motor 40 is connected to the side of the substrate layer 20 opposite to the pattern layer 10 and extends through the through hole 36 of the functional layer 30, which can reduce the impact of the vibration motor 40 on the thickness and volume of the hidden interior structure.

[0165] In some embodiments, refer to Figure 4 and Figure 6 As shown, a motor mounting base 23 is provided on the side of the substrate layer 20 opposite to the pattern layer 10. The motor mounting base 23 passes through the through hole 36 and is connected to the vibration motor 40. The motor mounting base 23 provides a mounting position for the vibration motor 40. The shape and connection method of the motor mounting base 23 and the vibration motor 40 are matched to effectively fix the vibration motor 40.

[0166] In some embodiments, the touch button 32 is a capacitive button, which is correspondingly disposed below the beacon pattern 15. The placement of the touch button 32 below the beacon pattern 15 effectively identifies the button position touched by the user and performs the corresponding action. At this time, referring to… Figure 7 As shown, the touch button 32 is arranged below the beacon pattern 15, and two light source devices 31 are arranged on opposite sides of the touch button 32.

[0167] When in use, the concealed interior structure can detect finger touch by checking the capacitance value formed between a finger and the touch button 32. It boasts advantages such as an attractive appearance, ease of use, and long lifespan. However, the presence of water film or droplets on the touch button 32, or accidental skin contact (i.e., unintentional skin contact with the touch button 32), can alter its capacitance, potentially leading to false touches. These false triggers of the concealed interior structure degrade the user experience.

[0168] In some embodiments, the hidden interior structure is further provided with an anti-accidental touch structure, which can effectively prevent accidental triggering of the hidden interior structure caused by accidental touch of the touch button 32.

[0169] In some embodiments, the circuit 38 includes a touch button 32 and a pressure sensor 33, which work together to prevent accidental touches.

[0170] In one example, refer to Figure 28 and Figure 29 , Figure 28 The image shows that when the user does not touch the touch button 32, the touch button 32 and the pressure sensor 33 are in an unbent state. Figure 29 The illustration shows that when a user touches the touch button 32, the user's finger presses the touch button 32 and the pressure sensor 33, causing the touch button 32 and the pressure sensor 33 to bend.

[0171] The pressure sensor 33 is used to detect the pressure on the hidden interior structure. When the user touches the button 32, its capacitance value will change. Only when the button 32 and the pressure sensor 33 are triggered at the same time can it be determined that the hidden interior structure is intentionally touched by the user to achieve the control function. This can effectively prevent accidental touches and the decline in user experience caused by accidental touches.

[0172] Among them, the pressure sensor 33 needs to have the required sensitivity, for example, the minimum pressure range that the pressure sensor 33 can detect is 5-50g, and the minimum deformation caused by the pressure is 0.01um-1um.

[0173] The pressure sensor 33 is positioned as follows (refer to...) Figure 14 , Figure 17 , Figure 19 As shown, the pressure sensor 33 is disposed on the functional layer 30, and the portion of the pressure sensor 33 protruding from the functional layer 30 is embedded in the substrate layer 20.

[0174] In some embodiments, the number of pressure sensors 33 is set according to usage requirements, for example, referring to Figure 7 The diagram shown illustrates a structure with a pressure sensor 33. (Refer to...) Figure 30 As shown, it illustrates a schematic diagram of a structure with two pressure sensors 33.

[0175] In some embodiments, the concealed interior structure further includes a pressure-sensing module 42, which is connected to the surface of the functional layer 30; the circuit 38 includes a touch button 32, which, together with the pressure-sensing module 42, is used to prevent accidental touches. Similarly, when both the touch button 32 and the pressure-sensing module 42 are triggered simultaneously, it is determined that the concealed interior structure is being intentionally touched by the user to achieve the control function, effectively preventing accidental touches and the resulting decrease in user experience.

[0176] The pressure sensing module 42 is a thin sheet structure used to measure and sense pressure changes. It senses changes in external pressure and converts them into a measurable voltage signal output. In this embodiment, the pressure sensing module 42 is disposed on the surface of the functional layer 30 away from the substrate layer 20. Compared to the pressure sensor 33 being disposed on the functional layer 30, this reduces the complexity of the functional layer 30.

[0177] The pressure sensing module 42 is positioned as follows (refer to...) Figure 16 , Figure 18 As shown, the pressure sensing module 42 is disposed on the surface of the functional layer 30 opposite to the substrate layer 20.

[0178] In some embodiments, the pressure sensing module 42 is attached to the surface of the functional layer 30 away from the substrate layer 20 by an adhesive, or a component such as a plastic column is provided on the surface of the functional layer 30 away from the substrate layer 20, and the external pressure value is transmitted through the contact of the plastic column or other component with the surface of the pressure sensing module 42.

[0179] Among them, the pressure sensing module 42 needs to have the required sensitivity, such as the minimum pressure range that the pressure sensing module 42 can detect is 10g-50g, and the minimum deformation caused by the pressure is 0.1um-1um, etc.

[0180] In some embodiments, refer to Figure 2 , Figure 13 , Figures 15 to 19 As shown, the pattern layer 10 includes a first film 11, a light-transmitting ink layer 13 and a light-blocking ink layer 14. The light-transmitting ink layer 13 and the light-blocking ink layer 14 are disposed on the first film 11, and a beacon pattern 15 is formed at the light-transmitting ink layer 13.

[0181] In this embodiment, the first diaphragm 11 is provided with a light-transmitting ink layer 13 and a light-blocking ink layer 14. A beacon pattern 15 is formed in the light-transmitting ink layer 13, through which light emitted by the LED lamp passes to display the beacon pattern 15. The light-blocking ink layer 14 is used to block the light from the LED lamp from passing through areas other than the beacon pattern 15, thus affecting the overall visual effect of the hidden interior structure and the user experience.

[0182] In some embodiments, the light-blocking ink layer 14 is formed by printing with a material that has low light transmittance or is opaque, such as light-blocking ink or light-blocking adhesive.

[0183] In some embodiments, the translucent ink layer 13 uses a film layer with a certain light transmittance (e.g., 15%-50%) to achieve a translucent display beacon pattern 15. The translucent ink layer 13 can also be formed by printing using a material with a certain light transmittance.

[0184] In some embodiments, the first diaphragm 11 is a light-diffusing diaphragm, which is more conducive to the uniform emission of light from the LED lamp from the beacon pattern 15, thereby enhancing the intensity, brightness and uniformity of the light.

[0185] In some embodiments, the pattern layer 10 further includes a translucent texture layer disposed on the surface of the pattern layer 10 opposite to the functional layer 30. The translucent texture layer is similar to or the same as the texture of the surrounding interior trim.

[0186] In this embodiment, the translucent texture layer can integrate the hidden interior structure with the surrounding interior of the vehicle, improving the consistency and aesthetics of the vehicle interior.

[0187] In some embodiments, a translucent texture layer is printed on the surface of the pattern layer 10 opposite to the surface of the functional layer 30.

[0188] In other embodiments, the concealed interior structure further includes a light-transmitting covering that covers the surface of the pattern layer 10 opposite to the functional layer 30. The light-transmitting covering can enhance the surface texture of the concealed interior structure, making it more integrated with the surrounding interior trim, thus improving the consistency and aesthetics of the vehicle's interior.

[0189] In some embodiments, the light-transmitting covering can be selected according to the vehicle's interior and usage requirements. This application does not specifically limit this. For example, the light-transmitting covering includes at least one of light-transmitting leather, wood grain, perforated material, and fabric.

[0190] In some embodiments, the substrate layer 20 has a connecting portion 24 on the surface opposite to the pattern layer 10, and the connecting portion 24 is connected to the vehicle body. The hidden interior structure is connected to the vehicle's hardware via the connecting portion 24, which has the advantages of simple and efficient connection. Moreover, the substrate layer 20 has sufficient strength to ensure the reliability of the connection between the connecting portion 24 and the vehicle's hardware.

[0191] In some embodiments, the substrate layer 20 and the connecting part 24 are an integral structural component. When the substrate layer 20 is injection molded, the substrate layer 20 and the connecting part 24 are formed synchronously during the manufacturing process, which can reduce manufacturing steps and save manufacturing costs.

[0192] This application does not specifically limit the structure of the connecting part 24 in the embodiments; refer to... Figure 3 As shown, the connecting part is, for example, a snap-fit ​​structure.

[0193] In a specific example, the hidden interior structure consists of a pattern layer 10, a substrate layer 20, and a functional layer 30. One side of the pattern layer 10 is printed with a corresponding beacon pattern 15; the other side of the pattern layer 10 is selectively printed with a translucent texture layer similar to the surrounding interior texture of the vehicle, or the other side of the pattern layer 10 is made similar to the surrounding interior texture by covering it with a translucent covering. The functional layer 30 is provided with conductors 35 for conductive circuitry, LED lights, and some electronic components 39. The conductors 35 can be formed by printing with conductive ink or conductive silver paste, etc. The LED lights are attached to corresponding positions on the functional layer 30 so that the beacon pattern 15 on the pattern layer 10 can be illuminated when the hidden interior structure is activated. The pattern layer 10, the functional layer 30, and the substrate layer 20 are formed into a single unit through insert injection molding between them. Injection molding can employ low-pressure injection molding to reduce the impact of the substrate on the LEDs and electronic components 39 on the functional layer 30, preventing them from being displaced and failing during the injection molding process. Alternatively, a potting process can be used to combine the pattern layer 10, the functional layer 30, and the substrate layer 20 into a single unit. To ensure consistent illumination of the beacon pattern 15 on the pattern layer 10 through the substrate layer 20, the first film 11 in the pattern layer 10 can be a light-diffusing film to improve the uniformity of the illumination from the LEDs onto the pattern layer 10.

[0194] In another specific example, the concealed interior structure includes a pattern layer 10, a substrate layer 20, and a functional layer. The pattern layer 10 is connected to the substrate layer 20 with the side featuring the beacon pattern 15 by an in-film embedding or transfer process to form a whole. On the side of the substrate layer 20 opposite to the pattern layer 10, there is a placement position (the placement position is the first mounting groove 21) for the LED light and some electronic components 39 on the functional layer 30, so that the LED light and some electronic components 39 on the functional layer 30 can be built into the substrate layer 20, while also ensuring that the functional layer 30 and the substrate layer 20 are effectively bonded and connected, avoiding light leakage. Meanwhile, in order to increase the light intensity and uniformity of the LED light illuminating the pattern layer 10, a focusing structure can be provided on the substrate layer 20. The focusing structure is designed differently depending on whether the LED light is top-emitting or side-emitting. For example, when the LED light is top-emitting, the focusing structure is the first mounting groove 21, which uses a triangular truncated pyramid structure or an arc-shaped groove to concentrate the light from the LED light, so that the light intensity and uniformity of the beacon pattern 15 illuminating the pattern layer 10 are better. When the LED light is side-emitting, the focusing structure is designed so that part of the sidewall of the first mounting groove 21 is an arc-shaped surface 27 to focus the light from the LED light, thereby achieving better light intensity and uniformity of the beacon pattern 15 on the pattern layer 10.

[0195] This application provides a hidden interior structure, as shown in the embodiments below. Figures 11 to 12 As shown, the hidden interior structure includes a pattern layer 10, a functional layer 30, and a substrate layer 20, which are stacked sequentially. The functional layer 30 is provided with a circuit 38 for implementing control functions.

[0196] In this embodiment, the hidden interior structure includes a pattern layer 10, a functional layer 30, and a substrate layer 20 stacked sequentially. The hidden interior structure has the advantage of simple structure. The hidden interior structure can realize control functions through the circuit 38 set on the functional layer 30. Compared with setting the circuit 38 on the printed circuit board, the structural complexity is further reduced, making the structure of the hidden interior structure simpler.

[0197] In some embodiments, the pattern layer 10, the functional layer 30, and the substrate layer 20 are an integral structural component, which enhances the dustproof and waterproof function of the hidden interior structure, improves its oxidation resistance, and avoids the occurrence of unreliable connections between the pattern layer 10, the functional layer 30, and the substrate layer 20. At the same time, it also reduces the installation process of the components in the hidden interior structure and improves the assembly efficiency.

[0198] In some embodiments, the concealed interior structure includes a third diaphragm having a beacon pattern 15 and circuitry as a pattern layer 10 and a functional layer 30, wherein the functional layer 30 is injection molded or potted to form a substrate layer 20 on the surface opposite to the pattern layer 10.

[0199] Furthermore, beacon patterns 15, wires 35, LED lights, and electronic components 39 are printed on one side of the third diaphragm, while textured patterns that are the same as or similar to those in the vehicle's interior trim are selectively printed on the other side of the third diaphragm as a translucent texture layer to integrate with the vehicle's interior trim.

[0200] In the above structure of this application embodiment, the pattern layer 10 and the functional layer 30 are integrated structural components to form a combined film layer. The side of the combined film layer where the LED light and electronic components 39 are located is formed into a substrate layer 20 by injection molding or potting, so that the pattern layer 10, the functional layer 30 and the substrate layer 20 are integrated structural components. The above structure can achieve dustproof and waterproof protection for the LED light and electronic components 39, and also reduce the weight of the hidden interior structure.

[0201] In a specific example, the structure and usage of the hidden interior trim are as follows:

[0202] The hidden interior structure can replace the physical and capacitive buttons in the vehicle. When the beacon pattern 15 is hidden, the hidden interior structure is consistent with the surrounding interior of the vehicle, thereby achieving the integration of the interior and enhancing the aesthetics of the vehicle interior.

[0203] The concealed interior structure can be used for sunroof control, seat adjustment, mode control, window control, air conditioning control, steering wheel buttons, etc. In a specific example, refer to... Figure 1 and Figure 2 As shown, the hidden interior structure is applied to the sunroof interior. When not activated, the appearance of the hidden interior structure is consistent with the surrounding interior texture of the vehicle, with the beacon patterns 15 hidden to achieve a concealed effect. When the user needs to use it, the hidden interior structure can be activated by double-clicking its surface. At this time, the six beacon patterns 15 on the hidden interior structure will light up, and the reading light areas 16 within the two circles will dimly illuminate. To adjust the sunroof or sunshade, the user can touch the corresponding beacon pattern 15. The touch button 32 below the touched beacon pattern 15 will send a signal to the vehicle's infotainment system to perform the corresponding function. While sending the signal, the touch button 32 will also provide vibration feedback from the vibration motor 40, or the light source device 31 will flash or change its light to remind the user to perform the operation.

[0204] When the hidden interior structure is applied to the sunroof interior, the reading light area 16 within the two circles emits a dim light to replace the corresponding beacon pattern function. To use the function corresponding to the six beacon patterns 15, simply press the corresponding beacon pattern 15 with your finger. The touch button 32 below the beacon pattern 15 will receive the pressure and perform the corresponding action and feedback. To use the reading light, press the circle; the brightness of the reading light area 16 will change. Multiple presses can be used to adjust to a suitable brightness. When no operation is needed, the beacon patterns 15 will turn off after a set time, hiding only the reading light function. When the reading light area 16 is no longer needed, double-tap the circle to turn off the reading light.

[0205] This application provides a method for preventing accidental touches in a concealed interior structure, applied to the aforementioned concealed interior structure. The touch button 32 in the concealed interior structure determines whether a touch action has occurred by detecting the capacitance value formed between the user's finger and the touch button 32. Compared to mechanical buttons, the concealed interior structure, without protruding buttons, has a more aesthetically pleasing appearance, is easier to use, and has a longer lifespan. However, the presence of a water film or droplets on the touch button 32 will change the capacitance, potentially leading to accidental touches; furthermore, accidental presses due to unintentional contact by the user or other objects cannot be completely avoided. Accidental triggering of the concealed interior structure degrades the user experience. Therefore, this application provides a method for preventing accidental touches in a concealed interior structure.

[0206] In some embodiments, the hidden interior structure includes a touch button 32 and a pressure sensor 33; the method for preventing accidental touches includes triggering the hidden interior structure to implement the control function corresponding to the touch button 32 only when a touch signal is received through the touch button 32 and a pressure signal is received simultaneously through the pressure sensor 33.

[0207] In this embodiment, the hidden interior structure is triggered only when a touch signal is received through the touch button 32 and a pressure signal is received simultaneously through the pressure sensor 33, so as to realize the control function corresponding to the touch button 32. This has a better function of preventing accidental touches and improving the user experience.

[0208] In some embodiments, the method for preventing accidental touch of the concealed interior structure includes the following steps, referring to... Figure 32 As shown:

[0209] S11, determine whether the touch button 32 is pressed.

[0210] In this step, the touch button 32 can be at least one of a capacitive button, a pressure sensor, or an infrared sensor. When the user touches the corresponding touch button 32, the touch button 32 will emit a corresponding signal.

[0211] In some embodiments, the method for determining whether the touch button 32 is pressed in step S11 includes the following steps, refer to Figure 33 As shown:

[0212] S111, obtain the first voltage change value of the touch button 32.

[0213] When a user touches the corresponding touch button 32, the first voltage change value of the touch button 32 will change.

[0214] The size of the touch button 32 needs to be convenient to press. For example, the touch button 32 can be a thin sheet structure. The size of the touch button 32 is selected according to the usage requirements. For example, the touch button 32 can be a cube structure, and the length and width of the cube can be no less than 8mm x 8mm or no less than 4mm x 4mm, etc. The larger the length and width of the touch button 32, the larger the first voltage change value converted from the capacitance change value of the touch button 32.

[0215] S112, when the first voltage change value is not zero, the touch button 32 receives a touch signal.

[0216] In this step, if the first voltage change value is not zero, it can be determined that the touch button 32 is pressed.

[0217] S12, determine whether the pressure sensor 33 is pressed.

[0218] In some embodiments, the method for determining whether the pressure sensor 33 is pressed in step S12 includes the following steps:

[0219] S121, acquire the second voltage change value of pressure sensor 33.

[0220] When the user touches the corresponding touch button 32 and causes effective deformation, the pressure sensor 33 undergoes effective deformation and its second voltage change value will change.

[0221] S122, when the second voltage change value is not zero, the pressure sensor 33 receives the pressure signal.

[0222] In this step, if the second voltage change value is not zero, it can be determined that the pressure sensor 33 is pressed.

[0223] The method described above for determining whether the pressure sensor 33 is being pressed in this application embodiment has the advantage of simplicity.

[0224] S13, the hidden interior structure is triggered to implement the control function corresponding to the touch button 32 only when a touch signal is received through the touch button 32 and a pressure signal is received through the pressure sensor 33 at the same time.

[0225] Specifically, when the user presses the beacon pattern 15 with their finger, the corresponding touch button 32 is pressed. The hidden interior structure detects the change in capacitance of the touch button 32, converting it into a first voltage change value, and detects the change in pressure from the pressure sensor, converting it into a second voltage change value. Further, referring to... Figure 28 As shown, when the user lightly touches the surface of the beacon pattern 15 with their finger, the first voltage change value is not zero, but no effective deformation occurs; the second voltage change value is zero, indicating that the hidden interior structure determines that the touch button 32 is not triggered. (Refer to...) Figure 29 As shown, when the user presses their finger on the surface of the beacon pattern 15, the first voltage change value is not zero and an effective deformation occurs. The pressure sensor 33 is also pressed and deformed, resulting in a second voltage change value that is not zero. The hidden interior structure determines that the touch button 32 is triggered and outputs the corresponding function control signal for the touch button 32. That is, when the touch button 32 and the pressure sensor 33 are pressed simultaneously, the hidden interior structure is triggered to realize the control function, which has a better function of preventing accidental touches and improving the user experience.

[0226] In some embodiments, the hidden interior structure has multiple touch buttons 32 and at least one pressure sensor 33. The hidden interior structure also determines whether the user intentionally pressed the touch button 32 based on the pressure distribution and the touch position.

[0227] In this embodiment, there are multiple touch buttons 32 and at least one pressure sensor 33. Each pressure sensor 33 has multiple second voltage change values, and the multiple pressure sensors 33 and the multiple second voltage change values ​​corresponding to the multiple pressure sensors 33 are combined to form a reference set. The method for preventing accidental touches further includes the following steps: The hidden interior structure is triggered to implement the control function corresponding to the touch button 32 only when a touch signal is received through the touch button 32 and a pressure signal is simultaneously received through the pressure sensor 33.

[0228] S131, Obtain the second voltage change value corresponding to all pressure sensors 33.

[0229] S132, compare all pressure sensors 33 and their corresponding second voltage change values ​​in the comparison set to obtain the pressing position.

[0230] S133, obtain the position of the touch button 32 that received the touch signal.

[0231] S134, compare the position of the touch button 32 that received the touch signal with the pressing position. If the position of the touch button 32 that received the touch signal corresponds to the pressing position, trigger the hidden interior structure to implement the control function corresponding to the touch button 32.

[0232] Furthermore, the pressure sensor 33 is calibrated by pressing the touch button 32. Pressing the touch button 32 includes pressing a single touch button 32, pressing multiple touch buttons 32 in combination, and pressing a partial or complete surface within the hidden interior structure. The second voltage change value calibrated by the pressure sensor 33 indicates the pressure distribution of the pressure sensor 33 when the touch button 32 is pressed. Multiple pressure sensors 33 and their corresponding second voltage change values ​​form a reference set. That is, the pressure distribution of multiple pressure sensors 33 can be used to determine whether a finger accurately presses the touch button 32, where one or more touch buttons 32 are pressed. The pressure sensor 33 and the touch button 32 together determine whether the finger pressing position and the position of the touch button 32 completely match. If they do, the touch button 32 is considered to be effectively triggered; if they do not completely match, the touch button 32 is considered not triggered.

[0233] In a specific example, refer to Figure 30 The diagram shown is a schematic representation of the distribution of touch buttons 32 and pressure sensors 33 in a hidden interior structure.

[0234] By pressing touch buttons 32a, 32b, 32c, and 32d individually; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32c simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32c and 32d simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32d simultaneously; or by pressing touch buttons 32b and 32d simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32c and 32d ...b simultaneously; or by pressing touch buttons 32c and 32d simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32c and 32d simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32a and 32b simultaneously; or by pressing touch buttons 32c, touch button 32d; touch button 32a, touch button 32b, touch button 32c, touch button 32c; and all cases of partial and full surface pressing of the hidden interior structure. By recording the second voltage change value of pressure sensor 33a and pressure sensor 33b each time it is pressed, the two pressure sensors are calibrated and combined into a reference set. The voltage change values ​​of pressure sensor 33a and pressure sensor 33b can be compared in the reference set to obtain a pressing position on the hidden interior structure.

[0235] The hidden interior structure determines whether the user has pressed other positions on the surface of the hidden interior structure besides the touch button 32 by judging the first voltage change value converted from the capacitance change value of the touch button 32 and the second voltage change value of the pressure sensor 33a and pressure sensor 33b. If the second voltage change value of the pressure sensor 33a and pressure sensor 33b indicates that the pressed position is consistent with the position of the touch button 32 with capacitance change, it is determined that the user intentionally pressed it, and the hidden interior structure controls the function of the touch button 32. If the second voltage change value of the pressure sensor 33a and pressure sensor 33b indicates that the pressed position is inconsistent with the position of the touch button 32 with capacitance change, it is determined that the user accidentally touched it, and the hidden interior structure does not trigger the button function.

[0236] In some embodiments, the position of the touch button 32 that receives the touch signal is compared with the pressing position. If the position of the touch button 32 that receives the touch signal corresponds to the pressing position, and the pressing position also includes positions other than the touch button 32, then it is determined to be a mis-touch.

[0237] In the application embodiment, the location of the pressed touch button 32 and other locations on the hidden interior structure are judged as accidental touches, making the judgment more accurate.

[0238] In one specific embodiment, reference is made to Figure 31 As shown, pressure sensor 33 determines the pressure distribution of the user's palm on the surface of the hidden interior structure. The second voltage change values ​​of pressure sensor 33a and pressure sensor 33b determine whether the pressed position is a local area or the entire area of ​​the hidden interior structure surface. If the pressed position is not only the touch button 32 but also other blank positions, it is determined that the position is inconsistent with the touch button 32 with capacitance change, indicating that the user has accidentally touched it, and the hidden interior structure does not trigger the touch button 32 function.

[0239] The method for preventing accidental touches of the hidden interior structure in this application embodiment can eliminate accidental triggering of the touch button 32 due to accidental touches, triggering due to other objects pressing on the touch button 32, and accidental triggering caused by the user's hand resting on the hidden interior structure. It has a better function of preventing accidental touches and improves the user experience.

[0240] This application provides a method for manufacturing a concealed interior structure. The manufacturing method includes the following steps, referred to... Figure 34 As shown:

[0241] S21, create pattern layer 10.

[0242] The pattern layer 10 has a beacon pattern 15, through which the control function corresponding to the touch button 32 at the beacon pattern 15 can be obtained.

[0243] In some embodiments, step S11 further includes the following steps:

[0244] S211, a printed layer is printed on the first diaphragm 11 to form a decorative diaphragm.

[0245] In this step, a decorative film is formed by printing on the first film 11, and the decorative film has a beacon pattern 15 on the pattern layer 10.

[0246] In some embodiments, the material of the first diaphragm 11 includes, but is not limited to, PMMA (polymethyl methacrylate), PC (polycarbonate), PET (polyethylene terephthalate), and PC (polycarbonate).

[0247] S212, which shapes the decorative film into a preset shape.

[0248] In this step, the decorative film is formed into a preset shape through heating, pressurizing, and vacuum adsorption. This preset shape needs to be adapted to the installation location of the hidden interior structure, such as the shape of the steering wheel or the rear seat armrest.

[0249] S213, The decorative film of the preset shape is cut to form the pattern layer 10.

[0250] In this step, the decorative film of the preset shape is cut into the required shape, thus forming the pattern layer 10.

[0251] S22, fabricate functional layer 30, which has circuitry 38 for implementing control functions.

[0252] In some embodiments, a functional layer 30 (functional film) is formed by arranging the circuit 38 and the electronic components 39 on the circuit 38 on a second film 37 through SMT placement processes such as solder paste printing, surface mounting, and soldering. The electronic components 39 include LED lights, silver paste circuits, vibration motors, etc.

[0253] In this step, an encapsulating plastic material 34 is disposed on the functional layer 30, and the encapsulating plastic material 34 encapsulates at least a portion of the circuit 38 onto the functional layer 30. The encapsulating plastic material 34 can encapsulate at least a portion of the circuit 38 onto the functional layer 30, avoiding damage to the circuit 38 and the electronic components 39 on the circuit 38 from impacts or other damage.

[0254] S23, at least one of injection molding and potting is performed between the pattern layer 10 and the functional layer 30 to form a substrate layer 20 between the pattern layer 10 and the functional layer 30.

[0255] In this step, the pattern layer 10 can be inserted into the upper mold, and the functional layer 30 can be clamped, bent and fed into the lower mold using a feeding device. The upper and lower molds are then closed, and a low-pressure injection molding machine is used to inject hot melt adhesive through the upper mold at low pressure. After the hot melt adhesive has cured, a demolding device is used to demold the mold, forming a complete hidden interior structure.

[0256] In this embodiment, by controlling the injection molding thickness of the substrate layer 20, the distance between the light source device 31 and the pattern layer 10 in the circuit 38 can be adjusted more easily, which facilitates the design of the light guide structure and light guide method in the hidden interior structure, making the light uniform and avoiding the light leakage phenomenon in the hidden interior structure.

[0257] In some embodiments, injection molding is low-pressure injection molding. The injection pressure of low-pressure injection molding will not damage the electronic component 39, and the electronic component 39 is less likely to be displaced or damaged during the injection molding process, thereby improving production efficiency and reducing product failure rate.

[0258] The method for manufacturing the concealed interior structure in this application involves fabricating a pattern layer 10 and a functional layer 30, respectively. At least one of injection molding or potting is then performed between the pattern layer 10 and the functional layer 30 to form a substrate layer 20. Manufacturing the pattern layer 10 and the functional layer 30 separately reduces the number of printing processes per sheet, minimizes the risks associated with the splitting process, and thus lowers the scrap rate. This effectively reduces the high manufacturing cost of current concealed interior structures.

[0259] This application provides another method for manufacturing a concealed interior structure. The manufacturing method includes the following steps, referred to... Figure 35 As shown:

[0260] S31, create pattern layer 10.

[0261] The steps for creating the pattern layer 10 can refer to step S21 described above, and will not be repeated in this embodiment.

[0262] S32, fabricate functional layer 30, functional layer 30 is provided with circuitry 38 for implementing control functions.

[0263] In some embodiments, a functional layer 30 (functional film) is formed by arranging the circuit 38 and the electronic components 39 on the circuit 38 on a second film 37 through SMT placement processes such as solder paste printing, surface mounting, and soldering. The electronic components 39 include LEDs, silver paste circuits, vibration motors, etc. The second film 37 can be referenced... Figure 13 , Figure 15 , Figure 20 As shown.

[0264] In some embodiments, the material of the second membrane 37 includes, but is not limited to, PMMA, PC, PET, and PC.

[0265] In some embodiments, an encapsulation plastic 34 is disposed on the functional layer 30, and the encapsulation plastic 34 encapsulates at least a portion of the circuitry 38 onto the functional layer 30.

[0266] At this time, the encapsulating plastic material 34 can encapsulate at least part of the circuit 38 onto the functional layer 30, avoiding damage such as bumps to the circuit 38 and the electronic components 39 on the circuit 38.

[0267] S33, at least one of injection molding and potting is performed on the pattern layer 10 to form a substrate layer 20 on the pattern layer 10.

[0268] In this embodiment, by controlling the injection molding thickness of the substrate layer 20, the distance between the light source device 31 and the pattern layer 10 in the circuit 38 can be adjusted more easily, which facilitates the design of the light guide structure and light guide method in the hidden interior structure, making the light uniform and avoiding the light leakage phenomenon in the hidden interior structure.

[0269] Moreover, since the substrate layer 20 is injection molded, the controllability of the thickness and shape of the substrate layer 20 greatly reduces the difficulty of arranging electronic components 39 and actuators in the functional layer 30, thus tapping the application potential of the functional layer 30.

[0270] In some embodiments, the substrate layer 20 is formed on the pattern layer 10 by low-pressure injection molding. The injection pressure of low-pressure injection molding will not damage the electronic components 39, and the electronic components 39 are not easily displaced or damaged during the injection molding process, thereby improving production efficiency and reducing product failure rate.

[0271] In some embodiments, the material of the substrate layer 20 includes, but is not limited to, PC, acrylic acid, ABS (a copolymer of acrylonitrile, butadiene and styrene), AES (polymerized by polymerizing acrylonitrile, ethylene and styrene under high temperature and pressure to form AES resin), PMMA, PI (polyimide), PPA (polyphthalamide), etc.

[0272] In this step, when at least one of injection molding or potting is performed on the pattern layer 10, a void-avoiding process is carried out to form a substrate layer 20 on the pattern layer 10, and a first mounting groove 21 is formed on the surface of the substrate layer 20 away from the surface of the pattern layer 10. The first mounting groove 21 is used to mount electronic components 39.

[0273] In some embodiments, step S23 further includes the following steps.

[0274] S231, fabricate a light-guiding uniform layer 50.

[0275] In this step, the first atomized PC film layer 51, the polarizing brightening film layer 53, and the second atomized PC film layer 52 are stacked to form a light guiding uniform layer 50. This light guiding uniform layer 50 makes the light guiding uniform in the hidden interior structure and improves the light leakage problem.

[0276] S232, at least one of injection molding or potting is performed between the pattern layer 10 and the light-guiding uniform layer 50 to form a substrate layer 20 between the pattern layer 10 and the light-guiding uniform layer 50. The functional layer 30 is connected to the surface of the light-guiding uniform layer 50 opposite to the pattern layer 10.

[0277] In this step, a clearance process is also required to form the first mounting slot 21. This first mounting slot 21 is used to mount electronic components 39.

[0278] S34, the functional layer 30 is connected to the surface of the substrate layer 20 away from the pattern layer 10.

[0279] In some embodiments, the functional layer 30 is connected to the substrate layer 20 by means of bonding, welding, microstructure fixing, printing, etc.

[0280] In this embodiment, the functional layer 30 is fabricated separately and then connected to the surface of the substrate layer 20 away from the pattern layer 10. Since the functional layer 30 does not participate in the injection molding process, this directly avoids the displacement or damage of electronic components 39 such as LEDs, resistors, and capacitors within the functional layer 30. Furthermore, by performing at least one of injection molding or potting on the pattern layer 10 to form the substrate layer 20, the outer surface of the substrate layer 20 is not affected by the wires 35 and electronic components 39, preventing embossing of the wires 35 and electronic component 39 leads. Simultaneously, the heating during injection molding is more uniform, avoiding surface shrinkage and other adverse effects on the functional film.

[0281] The method for manufacturing the concealed interior structure in this embodiment involves fabricating a pattern layer 10 and a functional layer 30 separately. At least one of injection molding or potting is performed on the pattern layer 10 to form a substrate layer 20. Finally, the functional layer 30 is bonded to the surface of the substrate layer 20 facing away from the pattern layer 10. Manufacturing the pattern layer 10 and functional layer 30 separately reduces the number of printing processes per sheet, minimizes the risks associated with the splitting process, and thus lowers the scrap rate. This effectively reduces the high manufacturing cost of current concealed interior structures.

[0282] This application provides a vehicle, which includes a vehicle body and has a hidden interior structure as described above.

[0283] In this embodiment of the invention, the hidden interior structure can serve as a function controller for the vehicle body, which can hide the beacon pattern 15 that serves as a function button, and the beacon pattern 15 does not protrude from the surface of the hidden interior structure, thereby improving space utilization and promoting interior integration.

[0284] In some embodiments, the vehicle body includes a steering wheel, roof, seat armrests, door panels, center console, and door handles; the concealed interior structure is connected to at least one of the steering wheel, roof, seat armrests, door panels, center console, and door handles.

[0285] In the vehicle of this invention embodiment, the location of the hidden interior structure is not specifically limited. For example, the hidden interior structure is connected to at least one of the above-mentioned steering wheel, roof, seat armrest, door panel, center console, and door handle to meet the user's usage needs and convenience regarding the location of the hidden interior structure.

[0286] Furthermore, when the hidden interior structure is located in the door handle, it is situated on the exterior of the vehicle body. When the vehicle is in sleep mode, the hidden interior structure enters a dormant state, its surface blending seamlessly with the door surface. When activated, the hidden interior structure displays functional information on the door.
