[0047] Exemplary embodiments of the present disclosure will be described in detail with reference to the drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0050] Referring to FIGS. 1-4, the hidden interior structure 100 includes a pattern layer 10, a substrate layer 20, and a functional layer 30, the pattern layer 10 and the substrate layer 20 being an integral structure, and the pattern layer 10, the substrate layer 20, and the functional layer 30 being sequentially stacked; as shown in FIGS. 12-15, the functional layer 30 is provided with a circuit 38 for realizing the control function.

[0051] For example, the pattern layer 10 is the outermost layer of the hidden interior structure, and the pattern layer 10 is used to exhibit the appearance of the hidden interior structure. The pattern layer 10 is provided with a beacon pattern 15, and through the beacon pattern 15, the control function corresponding to the beacon pattern 15 can be obtained to facilitate the user to operate and realize the control.

[0052] The substrate layer 20 is used to support and connect the pattern layer 10 and the functional layer 30, and the substrate layer 20 can make the hidden interior structure have a stable and reliable structure.

[0053] As shown in FIGS. 7 and 12, the functional layer 30 is provided with a circuit 38, the circuit 38 including electronic components 39 and wires 35, and through the circuit 38, the functional layer 30 is used to realize the control function of the hidden interior structure.

[0054] The hidden interior structure of some embodiments of the present disclosure comprises a pattern layer 10, a substrate layer 20 and a functional layer 30 arranged in sequence, and has the advantage of simple structure. The hidden interior structure can realize control function through the circuit 38 arranged on the functional layer 30, and further reduces the structural complexity compared with arranging the circuit 38 on a printed circuit board assembly (PCBA), so that the structure of the hidden interior structure is simpler.

[0055] Moreover, the pattern layer 10 and the substrate layer 20 are integrated structural members, which can effectively ensure the connection reliability of the pattern layer 10 and the substrate layer 20, enhance the waterproof and dustproof function of the hidden interior structure, and avoid the phenomenon of poor adhesion after oxidation when using adhesive connection.

[0056] In some embodiments, the pattern layer 10, the substrate layer 20 and the functional layer 30 are integrated structural members. In the above structure of some embodiments of the present disclosure, the integrated structural members make the dustproof and waterproof function of the hidden interior structure stronger, improve the oxidation resistance, avoid the occurrence of the situation that the pattern layer 10, the substrate layer 20 and the functional layer 30 are not connected reliably, and at the same time, reduce the mounting process of the internal components of the hidden interior structure and improve the assembly efficiency.

[0057] In some embodiments, the functional layer 30 is formed by embedding sheet low-pressure injection molding or pouring glue between the pattern layer 10 and the substrate layer 20, so that the pattern layer 10, the substrate layer 20 and the functional layer 30 are integrated structural members.

[0058] Low-pressure injection molding process is a packaging process method in which a very low injection pressure (for example, 1.5 bar-40 bar) is used to inject packaging materials into a mold and quickly solidify (for example, 5 seconds-50 seconds) to form a product. It is a process between potting and high-pressure injection molding process. Compared with other potting processes, the low-pressure injection molding process has the advantages of improving the performance of the terminal product, extremely low pressure during injection, no damage to electronic components 39, low temperature, low scrap rate, and excellent packaging protection effect, such as sealing, waterproof, moisture-proof, shock absorption, insulation and flame retardation.

[0059] In some embodiments of the present disclosure, the functional layer 30 is formed by low-pressure injection molding between the pattern layer 10 and the substrate layer 20, which can effectively reduce the scrap rate of the hidden interior structure and make the hidden interior structure have the above advantages.

[0060] In some embodiments, referring to FIG. 8, the surface of the substrate layer 20 away from the pattern layer 10 is connected with the functional layer 30.

[0061] In some embodiments, the 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 structure.

[0067] In some embodiments of the disclosure, the beacon pattern 15 is light-transmissive, and the light emitted by the light-emitting source device 31 can pass through the beacon pattern 15. The light-emitting source device 31 is arranged corresponding to the beacon pattern 15, which is more conducive to the light emitted by the light-emitting source device 31 illuminating the beacon pattern 15, so that the light intensity emitted by the beacon pattern 15 is brighter and more uniform.

[0068] In some embodiments of the disclosure, the hidden interior structure, the beacon pattern 15 is visible when the light-emitting source device 31 is on, and the beacon pattern 15 is hidden when the light-emitting source device 31 is off, that is, the beacon pattern 15 of the hidden interior structure is hidden when not in use, the hidden interior structure is integrated with the interior, and the vehicle interior integration is effectively realized.

[0069] The functional layer 30 of the hidden interior structure is provided with the light-emitting source device 31, the light emitted by the light-emitting source device 31 passes through the substrate layer 20 and the pattern layer 10 in turn and is emitted, the substrate layer 20 increases the light guide distance of the light-emitting source device 31, can make the light more uniformly distributed on the pattern layer 10, and makes the brightness of the beacon pattern 15 presented on the pattern layer 10 more clear and uniform.

[0070] In some embodiments, as shown in FIG. 7, the circuit 38 includes the conductive wire 35, the light source device 31 and the auxiliary control element, and the conductive wire 35 is connected with the light source device 31 and the auxiliary control element respectively.

[0072] In some embodiments, the functional layer 30 is provided with the conductive wire 35 formed by printing of conductive ink or conductive silver paste as a conductive circuit, and the light source device 31 and the auxiliary control element are arranged at corresponding positions on the functional layer 30, and the light source device 31 and the auxiliary control element are connected with the conductive wire 35.

[0073] In some embodiments, in order to improve the stability of signal transmission of the circuit 38 in the functional layer 30, a shielding circuit can also be arranged on the functional layer 30.

[0074] In some embodiments, as shown in FIG. 6 and FIG. 7, the auxiliary control element is arranged according to the function of the hidden interior structure, for example, the auxiliary control element includes at least one of a resistor, a capacitor, at least one touch button 32, an inductor, and at least one pressure sensor 33.

[0076] In some embodiments, as shown in FIG. 10, the functional layer 30 is provided with the encapsulation plastic material 34, and the encapsulation plastic material 34 at least encapsulates the light source device 31 and the auxiliary control element on the functional layer 30, so as 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 hidden interior structure.

[0077] For example, it avoids that the base material impacts the light source device 31 and the auxiliary control element during the integrated injection molding process of the functional layer 30 and the base material layer 20, which causes the risk of deviation or damage of the light source device 31 and the auxiliary control element, and improves the production yield of the hidden interior structure.

[0080] In some embodiments, the auxiliary control element protrudes from the surface of the functional layer 30, and the part of the auxiliary control element protruding from the functional layer 30 is also disposed in the first mounting groove 21.

[0081] In some embodiments, the substrate layer 20 is provided with a light condensing structure, which is used to concentrate the light of the light source device 31 to the beacon pattern 15. In some embodiments of the present disclosure, the light condensing structure can concentrate the light of the light source device 31 to the beacon pattern 15, so that the brightness of the beacon pattern 15 is more clear and uniform.

[0082] In some embodiments, the light condensing structure is the first mounting groove 21, and in this case, the hidden interior structure does not need to be additionally provided with a light condensing structure, and the structure of the hidden interior structure is simpler.

[0083] In some embodiments, referring to FIGS. 24-26, the first mounting groove 21 is enclosed into a triangular prism structure, the groove inner wall of the first mounting groove 21 is enclosed into the top surface, the bottom surface and the two side surfaces of the triangular prism structure, and the groove opening of the first mounting groove 21 is the other side surface in the triangular prism structure; or, the first mounting groove 21 is a circular face groove; or, the first mounting groove 21 is an arc face groove.

[0084] The part of the light source device 31 is inserted into the first mounting groove 21 through the groove opening of the first mounting groove 21, and the top surface, the bottom surface and the two side surfaces of the triangular prism structure enclosed by the groove inner wall of the first mounting groove 21 can realize light condensing, so that the light of the light source device 31 is concentrated to the corresponding beacon pattern 15, and the brightness of the beacon pattern 15 is more clear and uniform.

[0085] In this structure, the light source device 31 is top-emitting and outputs light from the top, and then the light is emitted through the substrate layer 20 and the beacon pattern 15 in sequence.

[0086] In some embodiments, referring to FIG. 26, the first mounting groove 21 is an arc surface groove. The arc surface groove can achieve light condensation, the light emitting source device 31 is top emitting and outputs light from the top, sequentially passes through the substrate layer 20 and the beacon pattern 15, and is emitted at the beacon pattern 15, so that the light of the light emitting source device 31 is condensed at the corresponding beacon pattern 15, and the brightness of the beacon pattern 15 is more clear and uniform.

[0088] In this structure, the light emitting source device 31 is also side emitting and outputs light from the top, sequentially passes through the substrate layer 20 and the beacon pattern 15. Further referring to FIG. 7, a structure schematic diagram of the light emitting source device 31 being side emitting is shown.

[0089] In some embodiments, the substrate layer 20 is provided with a light shielding baffle 25, which can be referred to FIG. 5. The light shielding baffle 25 divides the substrate layer 20 into multiple regions, and each region corresponds to at least one beacon pattern 15 and the light emitting source device 31 corresponding to the beacon pattern 15.

[0090] In the above embodiments of the present disclosure, the beacon pattern 15 and the light emitting source device 31 corresponding thereto are located in the same region and are one-to-one corresponding, the light emitted by the light emitting source device 31 is emitted from the beacon pattern 15 corresponding thereto and cannot be emitted from other beacon patterns 15 due to the shielding of the light shielding baffle 25, effectively shielding and blocking the propagation of light on the substrate layer 20, and avoiding confusion of light.

[0091] In some embodiments, when multiple light emitting source devices 31 emit light of multiple colors, the light shielding baffle 25 can effectively avoid the influence of the color consistency of the beacon pattern 15 caused by the light jumping phenomenon and effectively shield and block the propagation of light on the substrate layer 20.

[0092] In some embodiments, part of the light emitting source devices 31 can be used as reading lamps. Since the reading lamp needs to have relatively strong brightness, the light shielding baffle 25 can effectively shield the propagation of light of the reading lamp on the substrate layer 20, avoiding the interference of the relatively strong light of the reading lamp on other beacon patterns 15.

[0093] In some embodiments, referring to FIGS. 2 and 6, one beacon pattern 15 in each region can be correspondingly arranged with at least two light emitting source devices 31, so that the brightness of the beacon pattern 15 is more clear and uniform.

The above structure of some embodiments of the present disclosure has the advantage of simple structure. Moreover, the substrate layer 20 and the light-blocking strip 25 are independent components, and the light-blocking strip 25 does not affect the injection molding or glue pouring forming of the substrate layer 20.

[0095] In some embodiments, the light-blocking strip 25 is placed in the second mounting groove 22 by means of gluing or pasting, and then the functional layer 30 and the pattern layer 10 are connected, for example, the side of the functional layer 30 facing the pattern layer 10 is smeared with glue, and the functional layer 30 is tightly attached to the substrate layer 20.

[0096] In some embodiments, referring to FIGS. 10, 12 and 20, the circuit 38 includes an electronic component 39 and a packaging plastic material 34 for fixing the electronic component 39 on the functional layer 30, the periphery of the electronic component 39 is provided with a dam 341, and the packaging plastic material 34 fills the outside of the dam 341 and is divided into a light-transmitting region 342 and a light-blocking region 343.

[0097] In some embodiments of the present disclosure, the electronic component 39 herein can be various electronic components in the functional layer 30 as introduced above, can be a light-emitting source device 31, a resistor, a capacitor, a touch button 32, an inductor, a pressure sensor 33, etc., can be any appropriate component to be fixed on a film before packaging, and the electronic component 39 can be pre-welded and fixed on the film.

[0098] The dam 341 is constructed around the electronic component 39, and before packaging, a circle of dam glue is applied around the electronic component 39 to form the dam 341, which can effectively protect the electronic component 39 in the dam 341 from the influence of the packaging plastic material 34 during packaging. This solves the problem of easy displacement and poor fixation of the electronic component 39.

[0099] During packaging, the film to be packaged can be placed in a first low-pressure injection mold, a low-pressure injection machine is started, and light-blocking low-pressure injection packaging plastic material is injected into the first low-pressure injection mold and filled to a predetermined position. After the light-blocking plastic material solidifies in the mold, the film is taken out, and at this time, the light-blocking region 343 is formed on the film at a partial position.

[0100] Then, the film is placed in a second low-pressure injection mold, a low-pressure injection machine is started, and light-transmitting low-pressure injection packaging plastic material is injected into the second low-pressure injection mold and filled to at least the light-emitting surface of the light-emitting source device 31. The light-transmitting plastic material solidifies in the mold, the film is taken out, and the film is packaged. Of course, the light-transmitting packaging plastic material can be injected first, and then the light-blocking packaging plastic material is injected, that is, the order of packaging to form the light-blocking region 343 and the light-transmitting region 342 is not limited.

[0101] In addition, the positions and amounts of the light-transmitting region 342 and the light-blocking region 343 formed on the outer side of the dam 341 are not limited, and can be designed according to the shape of the dam 341 and the light guiding requirement. For example, when the outer contour of the dam 341 is a rectangle, one or more edges can be filled with the light-transmitting region 342, and the remaining edges can be filled with the light-blocking region 343.

[0102] In some embodiments of the present disclosure, the electronic component 39 can be fixed on the film by using low-temperature tin paste or conductive glue in advance, and then be fixed by the encapsulation plastic material 34, so as to play a reinforcing role and prevent the electronic component from being displaced and falling off in the last injection molding process of In-Mold Electronics (IME). Before encapsulation, the dam 341 is arranged around the electronic component 39, so as to avoid the influence of the encapsulation plastic material 34 on the electronic component 39 in the dam 341.

[0103] When encapsulation is performed, the light-blocking encapsulation plastic material and the light-transmitting encapsulation plastic material are encapsulated respectively, and the light-transmitting region 342 and the light-blocking region 343 are formed at the predetermined positions, so as to play a light guiding and light blocking role, solve the light leakage problem, and ensure that the light is more uniform.

[0104] In some embodiments, the circuit 38 includes a plurality of light source devices 31, the plurality of light source devices 31 are fixed to the functional layer 30 by the encapsulation plastic material 34, and the light-blocking region 343 is formed between adjacent light source devices 31 to prevent light leakage.

[0105] In some embodiments, referring to FIGS. 21 and 22, the circuit 38 includes a non-light source device 43, and at least the non-light source device 43 is arranged in the light-blocking region 343.

[0106] That is, the electronic component 39 can include the light source device 31 and the light source device 31. The light source device 31 can be the resistance, the capacitor, the touch button 32, the inductor, the pressure sensor 33, etc. mentioned above. At least the light-emitting surface of the light source device 31 is correspondingly provided with the light-transmitting region 342, so as to ensure that the emitted light of the light source device 31 can be emitted outward through the light-transmitting region 342.

[0107] The light-blocking region 343 can be filled around the light source device 31, the non-light-emitting surface of the light source device 31, and the non-light-transmitting position. The light-transmitting region 342 can be filled in the light-emitting surface of the light source device 31 and other light-transmitting positions.

[0108] For example, when the cross section of the light source device 31 is a square, as shown in FIG. 20, only one surface can be a light-emitting surface, the light-emitting surface is filled with the light-transmitting region 342, and the other three surfaces are filled with the light-blocking region 343.

[0109] As shown in FIG. 21 and FIG. 22, the light emitting source device 31 is filled with the light blocking area 343 around, and the surface of the light emitting source device 31 opposite to the light blocking area 343 is filled with the 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.

[0110] In some embodiments, the encapsulation plastic material includes a first encapsulation plastic material for light transmission and a second encapsulation plastic material for light blocking, the light blocking area 343 is formed by the second encapsulation plastic material, the first encapsulation plastic material forms the light transmitting area 342, and the light transmitting area 342 is arranged at the light emitting surface of the light emitting source device 31 and the light blocking area 343 is arranged at the non-light emitting surface of the light emitting source device 31.

[0111] In some embodiments, the light transmitting area 342 contains scattering particles in the corresponding first encapsulation plastic material. The scattering particles can improve the uniformity of light transmission, so as to improve the use effect of hiding the interior structure.

[0112] In some embodiments, the encapsulation plastic material 34 can be polyamide (PA), polyolefin (PO), polyurethane (PU), polycarbonate (PC) and the like, and the encapsulation plastic material 34 in the light transmitting area 342 contains scattering particles to form a light transmitting low pressure injection encapsulation plastic material. The encapsulation thickness of the encapsulation plastic material 34 can be 0.5-1.5mm (such as 0.5mm, 0.8mm, 1.2mm, 1.5mm).

[0113] In some embodiments, as shown in FIG. 21, the pattern unit of the pattern layer 10 and the electronic component 39 of the functional layer 30 can be located on a piece of the first film 11, and the smart surface structure includes the first film 11 and the pattern unit, the conductive circuit and the electronic component 39 arranged on the first film 11.

[0114] In some embodiments, the pattern unit, the conductive circuit and the electronic component can be respectively configured as a separate pattern layer 10, a conductive circuit layer 44 and an electronic component and encapsulation plastic material 45, and the pattern layer 10, the conductive circuit layer 44 and the electronic component and encapsulation plastic material 45 are arranged in sequence between the first film 11 and the substrate layer 20.

[0115] For example, the conductive circuit layer 44 can include conductive circuits, touch electrodes and pads. The pattern layer 10, the conductive circuits of the conductive circuit layer 44, the touch electrodes and the pads can be printed on the first film sheet 11, the electronic components 39 are fixed by conductive silver paste or low-temperature tin paste welding, the film sheet after the patching is put into a forming and blanking machine for forming and blanking, to form the film sheet to be packaged mentioned above, and is sequentially put into a first low-pressure injection mold and a second low-pressure injection mold, and a low-pressure injection molding machine is used to inject low-pressure injection packaging plastic material into the mold and quickly solidify, to package the light-transmitting area 342 and the light-blocking area 343, and to complete the reinforcement of the electronic components 39 and the like.

[0116] Finally, the packaged film sheet is put into the inner cavity of the injection mold, the molten plastic material is injected into the mold, the base material layer 20 is formed, and the IME product is completed.

[0117] In some embodiments, as shown in FIGS. 22 and 23, the pattern layer 10 and the functional layer 30 satisfy at least one of the following: the pattern layer 10 includes the first film sheet 11 and the pattern unit arranged on the first film sheet 11, or the functional layer 30 includes the second film sheet 37 and the conductive circuit and the electronic components 39 arranged on the second film sheet 37.

[0118] In some embodiments, the pattern unit is configured as a separate pattern layer 10, and the pattern layer 10 is located between the first film sheet 11 and the base material layer 20. The conductive circuit and the electronic components 39 are respectively configured as a separate conductive circuit layer 44 and an electronic component and packaging plastic material 45, and the conductive circuit layer 44 and the electronic component and packaging plastic material 45 are sequentially stacked and arranged between the base material layer 20 and the second film sheet 37.

[0119] The pattern layer 10 can be printed on the first film sheet 11, and the pattern layer 10 is put into a forming and blanking machine for forming and blanking to form the pattern layer 10; the conductive circuit layer 44 is printed on the second film sheet 37, the electronic components 39 are welded by conductive silver paste or low-temperature tin paste, the film sheet after the patching is put into a forming and blanking machine for forming and blanking, and is sequentially put into the inner cavities of the first low-pressure injection mold and the second low-pressure injection mold, and a low-pressure injection molding machine is used to inject low-pressure injection packaging plastic material into the mold and quickly solidify, to form the functional layer 30.

[0120] Finally, the pattern layer 10 and the functional layer 30 are put into the inner cavity of the injection mold, the molten plastic material is injected into the mold, and the IME product is completed. As to whether the pattern layer 10 and the functional layer 30 in the two embodiments in FIGS. 21 and 22 are in the form of a single patch layer or in the form of a pattern layer 10, an electronic component and packaging plastic material 45 being separately arranged on a film sheet, no more description is made.

[0121] In some embodiments, as shown in FIG. 20, a light blocking region 343 is arranged between two adjacent light emitting elements 311 in the functional layer 30, which can effectively solve the problem of light leakage. By adjusting the arrangement of the light transmission region 342 and the light blocking region 343, a uniform light emission effect can be achieved.

[0122] For example, the membrane is packaged by using a low-pressure injection molding process. The packaging plastic material is injected into the mold at a very low injection pressure, usually 1.5-40 bar, and quickly solidified (5-50 seconds) to form. Low-pressure injection molding is a process between potting and high-pressure injection molding. Compared with other potting processes, low-pressure injection molding process can improve the performance of the end product. The pressure is very low during injection, which will not damage the components. The temperature is low, the scrap rate is low, and the advantages of sealing, waterproofing, moisture-proofing, shock-absorbing, insulation, and flame-retardant are achieved.

[0123] In some embodiments, the hidden interior structure further comprises a light guiding uniform layer 50, the light guiding uniform layer 50 is connected with the base material layer 20, and the light guiding uniform layer 50 is located between the base material layer 20 and the functional layer 30.

[0124] In some embodiments of the present disclosure, the light guiding uniform layer 50 is used for uniform light guiding. The arrangement 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.

[0125] In some embodiments, referring to FIG. 27, the light guiding uniform layer 50 comprises a first fogging PC film layer 51, a polarized brightening film layer 53, and a second fogging PC film layer 52 arranged in a stack. The polarized brightening film layer 53 is arranged between the first fogging PC film layer 51 and the second fogging PC film layer 52.

[0126] In some embodiments of the present disclosure, the light guiding uniform layer 50 comprises a first fogging PC film layer 51 and a second fogging PC film layer 52 arranged in a stack, and a polarized brightening film layer 53 arranged between the first fogging PC film layer 51 and the second fogging PC film layer 52. For example, the first fogging PC film layer 51 is located on the light emitting side of the second fogging PC film layer 52,

[0127] In some embodiments, the light emitting side of the first fogging PC film layer 51 and the light entering side of the second fogging PC film layer 52 are both provided with a fogging layer, the fogging layer comprises convex hemispherical structures 54 of different sizes, and the larger convex hemispherical structures 54 and the smaller convex hemispherical structures 54 are arranged in an alternating manner on the first fogging PC film layer 51 and the second fogging PC film layer 52.

[0128] The convex hemispherical structure 54 can be made of liquid refractive index optical resin with low refractive index, and then be formed by ultraviolet (UV) light curing. When the light passes through the convex hemispherical structure 54, it will be scattered to produce a fogging effect, so that the light distribution is more uniform. The convex hemispherical structure 54 has a predetermined roughness (for example, Ra 0.8-2.0), which forms a fogging effect to achieve optical haze.

[0129] In some embodiments, the light-guiding uniform layer 50 can use a reflective polarized brightness enhancement film, which can continuously repeat the reflection of S waves and the penetration of P waves to enhance brightness. The polarized brightness enhancement film layer 53 is located between the LED lamp (which is an example of the light source device 31) and the light-collecting structure of the substrate layer 20. When the light passes through the polarized brightness enhancement film layer 53, the P-polarized light can directly penetrate through the polarized brightness enhancement film layer 53, while most of the S-polarized light is reflected back to the LED lamp by the polarized brightness enhancement film layer 53. During the reflection of the S-polarized light, it passes through each layer of material between the polarized brightness enhancement film layer 53 and the LED lamp, so that it is depolarized to become fully polarized light (including P-polarized light and S-polarized light) and then re-emitted from the LED lamp. In this way, the light is recycled to increase brightness.

[0130] The hidden interior structure of some embodiments of the present disclosure uses the light-guiding uniform layer 50 to match the light-collecting structure of the substrate layer 20 to achieve high-gain brightness increase, and combines the convex hemispherical structures 54 with different sizes on the surfaces of the first and second fogging PC film layers 51 and 52 to make the light produce light diffraction and achieve fogging and diffusion effects, thereby forming good light uniformity performance. This can significantly improve the penetration effect of the LED light and improve the display effect of the surface of the hidden interior structure, while the performance is more stable, safe, and durable.

[0131] In some embodiments, the hidden interior structure further includes an operation feedback element electrically connected to the functional layer 30, and the operation feedback element is used to control the feedback of the function. In some embodiments of the present disclosure, when the control function is realized through the hidden interior structure, the operation feedback element can provide feedback to enable the user to obtain the realization of the control function.

[0132] In some embodiments, the operation feedback element is at least one of a vibration motor 40 (see FIGS. 7 and 23) and a light source device 31 of the circuit 38.

[0133] For example, when the operation feedback element is the vibration motor 40, the vibration motor 40 vibrates for vibration feedback. When the user triggers the touch button 32 in the hidden interior structure, the vibration motor 40 vibrates to indicate that the user has effectively triggered the touch button 32.

[0134] When the operation feedback element is the light emitting source device 31 of the circuit 38, the light emitting 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, and the light emitting source device 31 emits light or changes light or emits specific light, indicating that the user effectively triggers the touch button 32.

[0135] In some embodiments, as shown in FIGS. 4 and 7, the functional layer 30 is provided with a through hole 36; the side of the substrate layer 20 away from the pattern layer 10 is connected with the vibration motor 40, and the vibration motor 40 passes through the through hole 36. In the above structure of the hidden interior structure, the vibration motor 40 is connected with the side of the substrate layer 20 away from the pattern layer 10 and passes through the through hole 36 of the functional layer 30, and the vibration motor 40 can reduce the influence on the thickness and volume of the hidden interior structure.

[0136] In some embodiments, as shown in FIGS. 4 and 6, the side of the substrate layer 20 away from the pattern layer 10 is provided with a motor mounting seat 23, the motor mounting seat 23 is provided in the through hole 36, and the motor mounting seat 23 is connected with the vibration motor 40. The motor mounting seat 23 provides a mounting position for the vibration motor 40, and the motor mounting seat 23 cooperates with the shape and connection mode of the vibration motor 40 to effectively fix the vibration motor 40.

[0137] In some embodiments, the touch button 32 is a capacitive button, and the touch button 32 is arranged corresponding to the beacon pattern 15 and is arranged below the beacon pattern 15. Arranging the touch button 32 below the beacon pattern 15 can effectively identify the position of the touch button touched by the user to perform corresponding actions. At this time, as shown in FIG. 7, the touch button 32 is arranged below the beacon pattern 15, and two light emitting source devices 31 are arranged on the opposite sides of the touch button 32.

[0138] The hidden interior structure has the advantages of beautiful appearance, easy use, and long service life when in use, and can judge whether there is a finger touch action by detecting the capacitance formed by the finger and the touch button 32.

[0139] However, if there is a water film or water droplets on the touch button 32, or the human skin accidentally touches (i.e., the human skin accidentally touches the touch button 32) the touch button 32, the capacitance of the touch button 32 will be changed, and false touch sensing may occur. False triggering of the hidden interior structure will reduce the user experience.

[0140] In some embodiments, the hidden interior structure is further provided with an anti-mis-touch structure, which can effectively prevent the hidden interior structure from being triggered by accidentally touching the touch button 32.

[0141] In some embodiments, the circuit 38 comprises the touch button 32 and the pressure sensor 33, which cooperate to prevent accidental touch.

[0142] In some embodiments, referring to FIG. 28 and FIG. 29, FIG. 28 shows that when the user does not touch the touch button 32, the touch button 32 and the pressure sensor 33 are in a non-bent state. FIG. 29 shows that when the user touches the touch button 32, the user's finger presses the touch button 32 and the pressure sensor 33 to bend the touch button 32 and the pressure sensor 33.

[0143] The pressure sensor 33 is used to detect the pressure received by the hidden interior structure, and the user touching the touch button 32 will cause a change in its capacitance value. When the touch button 32 and the pressure sensor 33 are triggered at the same time, it can be judged that the hidden interior structure is intentionally touched by the user to achieve a control function, which can effectively prevent accidental touch and the resulting decline in experience.

[0144] For example, the pressure sensor 33 needs to have a required sensitivity, such as a minimum pressure range of 5-50g, and a minimum deformation caused by pressure of 0.01um-1um (such as 0.01um, 0.1um, 0.5um, or 1um).

[0145] For example, the pressure sensor 33 is arranged on the functional layer 30, and the part of the pressure sensor 33 protruding from the functional layer 30 is embedded in the substrate layer 20, as shown in FIG. 14, FIG. 17, and FIG. 19.

[0146] In some embodiments, the number of pressure sensors 33 is set according to the use requirements, for example, referring to FIG. 7, FIG. 7 shows a structural diagram with one pressure sensor 33. Referring to FIG. 30, FIG. 30 shows a structural diagram with two pressure sensors 33.

[0147] In some embodiments, as shown in FIG. 16 and FIG. 18, the hidden interior structure further comprises a pressure sensing die 42 connected to the surface of the functional layer 30; the circuit 38 comprises the touch button 32, and the touch button 32 and the pressure sensing die 42 cooperate to prevent accidental touch. Similarly, when the touch button 32 and the pressure sensing die 42 are triggered at the same time, it can be judged that the hidden interior structure is intentionally touched by the user to achieve a control function, which can effectively prevent accidental touch and the resulting decline in experience.

[0148] For example, the pressure sensing die 42 is a thin sheet-like structure for measuring and sensing changes in pressure, which senses changes in external pressure and converts them into a measurable voltage signal output.

[0149] In some embodiments of the present disclosure, the pressure sensing die 42 is arranged on the surface of the functional layer 30 away from the substrate layer 20, and is arranged on the functional layer 30 relative to the pressure sensor 33, so as to reduce the complexity of the functional layer 30.

[0150] For example, the pressure sensing die 42 is arranged on the surface of the functional layer 30 away from the substrate layer 20, as shown in FIGS. 16 and 18.

[0151] In some embodiments, the pressure sensing die 42 is adhered to the surface of the functional layer 30 away from the substrate layer 20 by an adhesive, or a plastic column or the like is arranged on the surface of the functional layer 30 away from the substrate layer 20, and the external pressure value is transmitted by contacting the surface of the pressure sensing die 42 through the plastic column or the like.

[0152] For example, the pressure sensing die 42 needs to have a required sensitivity, for example, the minimum pressure range detected by the pressure sensing die 42 is 10g-50g (such as 10g, 20g, 30g or 50g), and the minimum deformation caused by the pressure is 0.1um-1um (such as 0.1um, 0.2um, 0.5um or 1um).

[0153] In some embodiments, referring to FIGS. 2, 13, 15-19, 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 arranged on the first film 11, and the beacon pattern 15 is formed at the light-transmitting ink layer 13.

[0154] In some embodiments of the present disclosure, the first film 11 is provided with the light-transmitting ink layer 13 and the light-blocking ink layer 14, the beacon pattern 15 is formed at the light-transmitting ink layer 13, and the light emitted by the LED lamp is transmitted through the light-transmitting ink layer 13 to display the beacon pattern 15. Other areas except the beacon pattern 15 are blocked by the light-blocking ink layer 14 to prevent the light of the LED lamp from being transmitted from the areas other than the beacon pattern 15, so as to affect the overall visual effect of the hidden interior structure and the user experience.

[0155] In some embodiments, the light-blocking ink layer 14 is printed using a material with low light transmittance or no light transmittance, such as light-blocking ink or light-blocking adhesive.

[0156] In some embodiments, the light-transmitting ink layer 13 is printed using a film layer with a certain light transmittance (for example, 15%-50%), so as to achieve light-transmitting display of the beacon pattern 15. The light-transmitting ink layer 13 can also be printed using a material with a certain light transmittance.

[0157] In some embodiments, the first film 11 is a homogenizing film, which is more conducive to the light of the LED lamp being evenly emitted from the beacon pattern 15, so as to enhance the intensity, brightness and uniformity of the light.

[0158] In some embodiments, the pattern layer 10 further comprises a light-transmitting texture layer, which is arranged on the surface of the pattern layer 10 away from the functional layer 30. The light-transmitting texture layer is similar or identical to the texture of the surrounding interior.

[0159] In some embodiments of the present disclosure, the light-transmitting texture layer can integrate the hidden interior structure with the surrounding interior of the vehicle, and improve the consistency and aesthetics of the interior of the vehicle.

[0160] In some embodiments, the surface of the pattern layer 10 away from the functional layer 30 is printed with the light-transmitting texture layer.

[0161] In some embodiments, the hidden interior structure further comprises a light-transmitting covering member, which covers the surface of the pattern layer 10 away from the functional layer 30. The light-transmitting covering member can increase the texture structure of the surface of the hidden interior structure, so that the texture structure of the surface of the hidden interior structure is integrated with the surrounding interior of the vehicle, and the consistency and aesthetics of the interior of the vehicle are improved.

[0162] In some embodiments, the light-transmitting covering member can be selected according to the surrounding interior of the vehicle and the use requirement, which is not limited in the present disclosure. For example, the light-transmitting covering member comprises at least one of light-transmitting leather, wood grain member, hollow member with hollow, and fabric.

[0163] In some embodiments, the surface of the substrate layer 20 away from the pattern layer 10 is provided with a connecting portion 24, which is connected with the vehicle body. The hidden interior structure is connected with the vehicle handle member through the connecting portion 24, which has the advantages of simple and efficient connection. Moreover, the substrate layer 20 has sufficient strength to ensure the firmness after the connecting portion 24 is connected with the vehicle handle member.

[0164] In some embodiments, the substrate layer 20 and the connecting portion 24 are an integral structure, and when the substrate layer 20 is injection molded, the substrate layer 20 is synchronously molded with the connecting portion 24 in the manufacturing process, which can reduce the manufacturing process and save the manufacturing cost.

[0165] The structure of the connecting portion 24 is not limited in the present disclosure. Referring to FIG. 3, the connecting portion is, for example, a buckle structure.

[0166] In some embodiments, the hidden interior structure is composed of the pattern layer 10, the substrate layer 20 and the functional layer 30.

[0167] For example, the pattern layer 10 has a corresponding beacon pattern 15 printed on one side; the other side of the pattern layer 10 is selectively printed with a light-transmissive texture layer similar to the texture of the surrounding interior of the vehicle, or the other side of the pattern layer 10 is made similar to the texture of the surrounding interior of the vehicle by covering a light-transmissive cover, etc.

[0168] The functional layer 30 is provided with a conductive wire 35 for a conductive circuit, an LED lamp, and some electronic components 39. The conductive wire 35 can be printed by conductive ink or conductive silver paste, etc. The LED lamp is attached to a corresponding position on the functional layer 30, so that the LED lamp can illuminate the beacon pattern 15 on the pattern layer 10 when the hidden interior structure is awakened. The pattern layer 10, the functional layer 30, and the substrate layer 20 are formed into one whole by insert molding between the pattern layer 10 and the functional layer 30.

[0169] The injection molding can adopt a low-pressure injection molding method to reduce the impact of the substrate on the LED lamp and the electronic components 39 on the functional layer 30, so as to avoid the LED lamp and the electronic components 39 from being offset and invalid in the injection molding process. Alternatively, a glue filling process can be used to combine the pattern layer 10, the functional layer 30, and the substrate layer 20 into one whole. In order to ensure the light consistency of the light emitted by the LED lamp on the functional layer 30 to illuminate the beacon pattern 15 on the pattern layer 10 through the substrate layer 20, the first film sheet 11 in the pattern layer 10 can be selected as a uniform light film sheet to improve the uniformity of the light emitted by the LED lamp on the pattern layer 10.

[0170] In some embodiments, the hidden interior structure includes the pattern layer 10, the substrate layer 20, and the functional layer.

[0171] The pattern layer 10 is connected to the substrate layer 20 as one whole by an in-film insert sheet or a transfer printing process, and the side of the pattern layer 10 provided with the beacon pattern 15 is connected to the substrate layer 20 as one whole. The placement position (which is a first mounting groove 21) of the LED lamp and some electronic components 39 on the functional layer 30 is arranged on the side of the substrate layer 20 away from the pattern layer 10, so that the LED lamp and some electronic components 39 on the functional layer 30 can be built-in in the substrate layer 20, and at the same time, the functional layer 30 and the substrate layer 20 can be effectively connected and attached, avoiding the occurrence of light leakage.

[0172] And, in order to increase the light intensity and uniformity of the LED light irradiated to the pattern layer 10, a light collecting structure can be arranged on the substrate layer 20, which is designed differently according to whether the LED light is top-emitting or side-emitting. For example, when the LED light is top-emitting, the light collecting structure is the first mounting groove 21, that is, the light rays of the LED light are more concentrated by the triangular prism structure or the arc-shaped groove, so that the light intensity and uniformity of the beacon pattern 15 on the pattern layer 10 are better; when the LED light is side-emitting, the light collecting structure is designed by making the arc-shaped surface 27 of the side wall of the first mounting groove 21 to perform the light collecting function of the LED light, so that the light intensity and uniformity of the beacon pattern 15 on the pattern layer 10 are better.

[0173] Some embodiments of the present disclosure provide a hidden interior structure. Referring to FIGS. 11 and 12, the hidden interior structure includes a pattern layer 10, a functional layer 30, and a substrate layer 20, which are sequentially stacked. The functional layer 30 is provided with a circuit 38 for realizing a control function.

[0174] In some embodiments of the present disclosure, the hidden interior structure includes a pattern layer 10, a functional layer 30, and a substrate layer 20, which are sequentially stacked. The hidden interior structure has the advantage of simple structure. The hidden interior structure can realize a control function through the circuit 38 arranged on the functional layer 30, which further reduces the structural complexity to make the structure of the hidden interior structure simpler, compared with arranging the circuit 38 on a printed circuit board.

[0175] In some embodiments, the pattern layer 10, the functional layer 30, and the substrate layer 20 are an integral structure, so that the hidden interior structure has strong dustproof and waterproof functions, improved oxidation resistance, and avoids the occurrence of a situation that the pattern layer 10, the functional layer 30, and the substrate layer 20 are not firmly connected. At the same time, the mounting process of the internal components of the hidden interior structure is reduced, and the assembly efficiency is improved.

[0176] In some embodiments, the hidden interior structure includes a third film, which is provided with a beacon pattern 15 and a circuit as the pattern layer 10 and the functional layer 30. The surface of the functional layer 30 away from the pattern layer 10 is injection molded or glued to form the substrate layer 20.

[0177] For example, the beacon pattern 15, the lead wire 35, the LED light, and the electronic component 39 are printed on one side surface of the third film, and a texture pattern identical or similar to the surrounding interior of the vehicle is selectively printed on the other side surface of the third film as a light-transmitting texture layer to integrate with the surrounding interior of the vehicle.

[0178] In the above structure of some embodiments of the present disclosure, the pattern layer 10 and the functional layer 30 are formed into a combined film layer, and the side of the combined film layer provided with the LED lamp and the electronic component 39 is formed into the base material layer 20 by injection molding or glue pouring, so that the pattern layer 10, the functional layer 30 and the base material layer 20 are formed into an integrated structure. The above structure can realize dustproof and waterproof protection of the LED lamp and the electronic component 39, and also reduces the weight of the hidden interior structure.

[0179] In some embodiments, the structure of the hidden interior structure and the use mode are as follows:

[0180] 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 unified with the surrounding interior of the vehicle, so as to achieve the integration of the interior of the vehicle and enhance the beauty of the interior of the vehicle.

[0181] The hidden interior structure can be used for sunroof control, seat adjustment, mode control, window control, air conditioning adjustment, steering wheel button, etc.

[0182] For example, referring to FIG. 1 and FIG. 2, the hidden interior structure is applied to the sunroof interior. When the hidden interior structure is not awakened, the appearance of the hidden interior structure is consistent with the texture of the surrounding interior of the vehicle, and the beacon pattern 15 is hidden to achieve the hiding effect.

[0183] When the user needs to use it, the hidden interior structure can be activated by double-clicking the surface of the hidden interior structure, at which time the six beacon patterns 15 on the hidden interior structure will light up and the reading light area 16 in the two circles will be slightly bright. The user can touch the corresponding beacon pattern 15 to adjust the sunroof or sunshade curtain, etc. The touch button 32 under the touched beacon pattern 15 will send a signal to the vehicle machine to realize the corresponding function. At the same time, the touch button 32 will also have a vibration feedback provided by the vibration motor 40, or the light of the light source device 31 will flash or change to remind the user to perform the operation.

[0184] When the hidden interior structure is applied to the sunroof interior, the reading light area 16 in the two circles emits weak light to replace the corresponding beacon pattern function of the reading light. When the six beacon pattern 15 corresponding functions are needed, only the corresponding beacon pattern 15 needs to be pressed by the finger. The touch button 32 under the beacon pattern 15 will receive the pressure and make corresponding actions and feedback.

[0185] When the reading light needs to be used, the circle needs to be pressed, and the brightness of the reading light area 16 will change. The brightness can be adjusted to the appropriate brightness by pressing multiple times. If no operation is needed, the beacon pattern 15 will be turned off and hidden for a set time to only keep the function of the reading light. When the reading light area 16 does not need to be used, the reading light can be turned off by double-clicking the circle.

[0186] Some embodiments of the present disclosure provide a hidden interior structure anti-mis-touch method applied to the hidden interior structure described above. The touch button 32 in the hidden interior structure judges whether there is a touch action by detecting the capacitance value formed by the user's finger and the touch button 32. Compared with mechanical buttons, the hidden interior structure has a beautiful appearance, is easy to use, and has a long service life.

[0187] However, when there is a water film or water droplets on the touch button 32, the capacitance will change, and false touch sensing may occur. Moreover, false pressing caused by the user or other objects accidentally touching the touch button 32 cannot be avoided. The false triggering of the hidden interior structure will cause the user's experience to decrease. Therefore, some embodiments of the present disclosure provide a hidden interior structure anti-mis-touch method.

[0188] In some embodiments, as shown in FIGS. 16-19, the hidden interior structure includes at least one touch button 32 and at least one pressure sensor 33; and the anti-mis-touch method includes: 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, triggering the hidden interior structure to implement a control function corresponding to the touch button 32.

[0189] In some embodiments of the present disclosure, 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, triggering the hidden interior structure to implement a control function corresponding to the touch button 32, which has a good anti-mis-touch function and improves the user's experience.

[0190] In some embodiments, referring to FIG. 32, the hidden interior structure anti-mis-touch method includes the following steps S11-S13.

[0191] S11, judging whether the touch button 32 is pressed.

[0192] In this step, the touch button 32 can be at least one of a capacitive button, a pressure sensor, and an infrared sensor. When the user touches the corresponding touch button 32, the touch button 32 will send a corresponding signal.

[0193] In some embodiments, referring to FIG. 33, the method for judging whether the touch button 32 is pressed in step S11 includes the following steps S111-S112.

[0194] S111, obtain a first voltage variation value of the touch key 32.

[0195] When the user touches the corresponding touch key 32, the touch key 32 is pressed, and the first voltage variation value of the touch key 32 changes.

[0196] The size of the touch key 32 needs to be convenient to press. For example, the touch key 32 is in a sheet structure, and the size of the touch key 32 is selected according to the use requirement. For example, the touch key 32 is in a cube structure, and the length and width of the cube are not less than 8mm x 8mm, not less than 4mm x 4mm, etc. The greater the length and width of the touch key 32, the greater the first voltage variation value converted by the capacitance variation value of the touch key 32.

[0197] S112, in the case that the first voltage variation value is not zero, the touch key 32 receives a touch signal.

[0198] In this step, in the case that the first voltage variation value is not zero, it can be judged that the touch key 32 is pressed.

[0199] S12, judge whether the pressure sensor 33 is pressed.

[0200] In some embodiments, referring to FIG. 33, the method for judging whether the pressure sensor 33 is pressed in step S12 includes steps S121-S122.

[0201] S121, obtain a second voltage variation value of the pressure sensor 33.

[0202] When the user touches the corresponding touch key 32 and generates an effective deformation, the pressure sensor 33 generates an effective deformation, and the second voltage variation value of the pressure sensor 33 changes.

[0203] S122, in the case that the second voltage variation value is not zero, the pressure sensor 33 receives a pressure signal.

[0204] In this step, in the case that the second voltage variation value is not zero, it can be judged that the pressure sensor 33 is pressed.

[0205] The method for judging whether the pressure sensor 33 is pressed described above in some embodiments of the present disclosure has the advantage of simplicity.

[0206] S13, only when the touch signal is received through the touch key 32 and the pressure signal is received through the pressure sensor 33 at the same time, the hidden interior structure is triggered to be used to realize the control function corresponding to the touch key 32.

[0207] For example, when the user presses the beacon pattern 15 with a finger, the corresponding touch button 32 of the beacon pattern 15 is pressed, the hidden interior structure detects the capacitance change value of the touch button 32 and converts it into a first voltage change value, and detects the pressure change value of the pressure sensor and converts it into a second voltage change value.

[0208] For example, referring to FIG. 28, when the user taps the surface of the beacon pattern 15 with a finger, the first voltage change value is not zero, but no effective deformation is generated, and the second voltage change value is zero. The hidden interior structure determines that the touch button 32 is not triggered.

[0209] Referring to FIG. 29, when the user presses the surface of the beacon pattern 15 with a finger, the first voltage change value is not zero, and effective deformation is generated. The pressure sensor 33 is pressed and deformed, and the second voltage change value is not zero. The hidden interior structure determines that the touch button 32 is triggered, and outputs a function control signal corresponding to the touch button 32. That is, when the touch button 32 and the pressure sensor 33 are pressed at the same time, the hidden interior structure is triggered to realize the control function, which has a good anti-misoperation function and improves the user experience.

[0210] In some embodiments, the at least one touch button 32 includes a plurality of touch buttons 32, and the hidden interior structure further determines whether the user intentionally presses the touch button 32 by pressure distribution and touch position.

[0211] In some embodiments of the present disclosure, any one of the at least one pressure sensor 33 has a plurality of second voltage change values, and the at least one pressure sensor 33 and the at least two second voltage change values corresponding to the at least one pressure sensor 33 are combined into a comparison set.

[0212] The above-mentioned triggering of the hidden interior structure to realize the control function corresponding to the touch button 32 only when the touch signal is received through the touch button 32 and the pressure signal is received through the pressure sensor 33 at the same time further includes steps S131-S134.

[0213] S131, obtaining at least two second voltage change values corresponding to the at least one pressure sensor 33.

[0214] S132, comparing the at least one pressure sensor 33 and the at least two second voltage change values corresponding thereto in the comparison set to obtain the pressed position.

[0215] S133, obtaining the position of the touch button 32 receiving the touch signal.

[0216] S134, compare the position of the touch key 32 receiving the touch signal with the pressing position, if the position of the touch key 32 receiving the touch signal corresponds to the pressing position, trigger the hidden interior structure to realize the control function corresponding to the touch key 32.

[0217] For example, by calibrating the pressure sensor 33 when pressing the touch key 32, the pressing of the touch key 32 includes the case that a single touch key 32 is pressed, multiple touch keys 32 are pressed in combination, and the local surface of the hidden interior structure is pressed, and the whole surface is pressed.

[0218] The second voltage change value of the calibrated pressure sensor 33 indicates the pressure distribution of the pressure sensor 33 when the touch key 32 is pressed. Multiple pressure sensors 33 and multiple second voltage change values corresponding to multiple pressure sensors 33 are combined into a comparison set, that is, whether the finger accurately presses the touch key 32 can be determined by the pressure distribution of multiple pressure sensors 33, and the pressed touch key 32 is one or more.

[0219] The pressure sensor 33 and the touch key 32 together determine whether the finger pressing position completely matches the position of the touch key 32. If yes, it is determined that the touch key 32 is triggered effectively. If it is determined that it is not completely matched, it is determined that the touch key 32 is not triggered.

[0220] In some embodiments, referring to FIG. 30, FIG. 30 is a schematic diagram of the distribution of the touch key 32 and the pressure sensor 33 in a hidden interior structure.

[0221] By individually pressing the touch button 32a, the touch button 32b, the touch button 32c, the touch button 32d, simultaneously pressing the touch button 32a and the touch button 32b, simultaneously pressing the touch button 32a and the touch button 32c, simultaneously pressing the touch button 32a and the touch button 32d, simultaneously pressing the touch button 32b and the touch button 32c, simultaneously pressing the touch button 32b and the touch button 32d, simultaneously pressing the touch button 32c and the touch button 32d, simultaneously pressing the touch button 32a, the touch button 32b and the touch button 32c, simultaneously pressing the touch button 32a, the touch button 32b and the touch button 32d, simultaneously pressing the touch button 32a, the touch button 32c and the touch button 32d, simultaneously pressing the touch button 32b, the touch button 32c and the touch button 32d, simultaneously pressing the touch button 32a, the touch button 32b, the touch button 32c and the touch button 32d, and all cases of partially pressing and fully pressing the local surface of the hidden interior structure, the two pressure sensors are calibrated by recording the second voltage change value of the pressure sensor 33a and the pressure sensor 33b at each pressing, and the calibration results are combined into a control set. The voltage change value of the pressure sensor 33a and the pressure sensor 33b can be compared in the control set to obtain the pressed position on the hidden interior structure.

[0222] The hidden interior structure determines whether the user presses other positions on the surface of the hidden interior structure in addition to the touch button 32 by comparing the first voltage change value converted from the capacitance change value of the touch button 32 with the second voltage change value of the pressure sensor 33a and the pressure sensor 33b. If the second voltage change value of the pressure sensor 33a and the pressure sensor 33b determines that the pressed position is consistent with the position of the touch button 32 with capacitance change, it is determined that the user intentionally presses, 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 the pressure sensor 33b determines that the pressed position is inconsistent with the position of the touch button 32 with capacitance change, it is determined that the user is mistaken, and the hidden interior structure does not trigger the button function.

[0223] In some embodiments, the position of the touch button 32 receiving the touch signal is compared with the pressed position. If the position of the touch button 32 receiving the touch signal corresponds to the pressed position, and the pressed position also includes positions other than the touch button 32, it is determined that it is a mistaken touch.

[0224] In some embodiments, the hidden interior structure has a pressed touch button 32 position and positions other than the pressed touch button 32 position, which is more accurate for determining mistaken touch.

[0225] In some embodiments, referring to FIG. 31, the pressure sensor 33 judges the pressure distribution of the user's palm on the surface of the hidden interior structure, and the second voltage change value of the pressure sensor 33a and the pressure sensor 33b judges that the pressed position is a local area or the entire area of the surface of the hidden interior structure. If the pressed position is not only the touch button 32 but also other blank positions, it is judged that the position is inconsistent with the position of the touch button 32 with a capacitance change, which is a user's false touch, and the hidden interior structure does not trigger the function of the touch button 32.

[0226] The false touch prevention method of the hidden interior structure of some embodiments of the present disclosure can exclude the false touch caused by the false triggering of the touch button 32, the triggering caused by other objects pressing the touch button 32, and the false triggering caused by the user's hand resting on the hidden interior structure, has a better false touch prevention function, and improves the user's experience.

[0235] In this step, the decorative film is formed into a preset shape by heating, pressing, and vacuum adsorption forming. The preset shape needs to adapt to the installation position of the hidden interior structure, such as the shape of the position of the steering wheel and the rear seat armrest.

[0236] S213, cutting the decorative film in the preset shape to form the pattern layer 10.

[0243] In some embodiments of the present disclosure, by controlling the injection molding thickness of the base material layer 20, the distance between the light source device 31 in the circuit 38 and the pattern layer 10 can be easily adjusted, the design of the light guide structure and the light guide mode in the hidden interior structure is facilitated, the light is uniform, and the light leakage phenomenon of the hidden interior structure is avoided.

[0244] In some embodiments, the injection molding is low-pressure injection molding. The injection pressure of the low-pressure injection molding does not cause damage to the electronic components 39, and the electronic components 39 are not easily displaced or damaged in the injection molding process, thereby improving the production efficiency and reducing the product failure rate.

[0245] The manufacturing method of the hidden interior structure in some embodiments of the present disclosure separately manufactures the pattern layer 10 and the functional layer 30, and at least one of injection molding and glue filling is performed between the pattern layer 10 and the functional layer 30 to form the base material layer 20 between the pattern layer 10 and the functional layer 30. The pattern layer 10 and the functional layer 30 are manufactured separately, the printing processing times of the single film sheet are reduced, the process risk is split, and the scrap rate is reduced, which effectively reduces the high manufacturing cost problem of the current hidden interior structure.

[0254] S33, at least one of injection molding and glue filling is performed on the pattern layer 10 to form the base material layer 20 on the pattern layer 10.

[0255] In some embodiments of the present disclosure, by controlling the injection molding thickness of the base material layer 20, the distance between the light source device 31 in the circuit 38 and the pattern layer 10 can be easily adjusted, which is convenient for the design of the light guide structure and the light guide mode in the hidden interior structure, makes the light uniform, and avoids the light leakage phenomenon of the hidden interior structure.

[0256] Moreover, the base material layer 20 is injection molded, and the controllability of the thickness and shape of the base material layer 20 greatly reduces the arrangement difficulty of the electronic components 39 and actuators in the functional layer 30, and excavates the application potential of the functional layer 30.

[0266] In some embodiments, the functional layer 30 is connected to the substrate layer 20 by adhesion, welding, microstructure fixation, printing, etc.

[0267] In some embodiments of the present disclosure, the functional layer 30 is made separately and then connected to the surface of the substrate layer 20 away from the pattern layer 10.
