[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are not only some embodiments of this utility model, but all embodiments. The components of the embodiments of this utility model can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.

[0027] Example:

[0028] like Figures 1 to 3 As shown, this embodiment provides a touch-sensitive interior trim component for automobiles, including:

[0029] A light-transmitting frame 1, on which a substrate 2 is provided;

[0030] The wood veneer layer is set on the front wall of the substrate 2. A backing layer is set between the wood veneer layer and the substrate 2. Multiple hollow patterns are set on the wood veneer layer, and the multiple hollow patterns penetrate the wood veneer layer and the backing layer.

[0031] PCB board 3 is set on the rear wall of substrate 2. PCB board 3 integrates multiple spaced LED beads and touch processor. Capacitive touch film 4 and light shield 5 are arranged sequentially from front to back between PCB board 3 and substrate 2. The light shield 5 is used to make multiple hollow patterns correspond to multiple LED beads respectively. Capacitive touch film 4 is electrically connected to touch processor so that touch processor generates touch signal according to the action of capacitive touch film 4.

[0032] In this embodiment, since the frame 1 is a light-transmitting structure, that is, the frame 1 of the interior component is made of a light-transmitting material, and a substrate 2 is provided on the frame 1, firstly, a base layer and a wood veneer layer are sequentially provided on the front wall of the substrate 2 from back to front. In this way, the adhesion between the wood veneer layer and the substrate 2 can be increased by the base layer. Multiple hollow patterns are laser-engraved on the wood veneer layer, so that the multiple hollow patterns form multiple function button areas. That is, the function buttons may include the in-vehicle air conditioning, seat adjustment, etc. When laser engraving, the wood veneer layer and the base layer must be completely engraved through, so that the corresponding parts of the hollow patterns can achieve light transmission, thereby ensuring the uniformity of the product's luminous brightness. On the rear wall of the substrate 2, a capacitive touch film 4, a light shield 5, and a PCB board 3 are sequentially provided from front to back. Since the PCB board 3 integrates multiple spaced LED beads and touch processors, the light shield 5 is used to shield the light emitted by multiple LED beads, thereby avoiding the light from two adjacent LED beads. The emitted light interacts with each other, thereby enhancing the overall visual experience of the product. Simultaneously, the capacitive touch film 4 is electrically connected to the touch processor. When a user's finger or other conductor presses on one or more of the hollowed-out patterns—that is, when the user's finger touches the corresponding function button area, such as the car's air conditioning or seat adjustment—the corresponding icon will provide feedback to the user through sound, color changes, and / or vibration. The capacitive touch film 4 will form a capacitive coupling effect, changing the charge distribution on it. This change is detected by the touch processor and converted into a corresponding touch signal, thereby controlling the corresponding LED to operate. Alternatively, the function command corresponding to the current touch signal can be sent to the car controller to execute the function command. This improves the flexibility and convenience of interaction. Its simple structure effectively solves the problem of uneven brightness of different patterns or products in genuine wood interior trim, thus giving it good durability and scratch resistance.

[0033] To further improve the uniformity of the brightness of the real wood interior trim, when laser-engraving patterns on the wood veneer, in addition to removing the wood veneer and the base layer, the substrate 2 on the frame 1 can also be engraved and atomized, so that the rear end of the hollow pattern extends to the substrate 2, but does not completely penetrate the substrate 2. Then, the residual thickness at this position on the substrate 2 is measured using a laser engraving machine. This ensures that the residual thickness of the substrate 2 at the position corresponding to the hollow pattern is consistent, thereby ensuring that the hollow pattern can be cleanly engraved on the wood veneer, thus solving the problem of uneven brightness of different patterns or different products. Of course, it can also further improve the accuracy of the capacitive touch film 4.

[0034] Furthermore, multiple light-blocking channels 51 are spaced apart on the light-blocking frame 5. The rear ends of the multiple light-blocking channels 51 are respectively arranged corresponding to multiple LED beads, and the front ends are respectively arranged corresponding to multiple hollow patterns, so as to block the light emitted by multiple LED beads respectively.

[0035] Preferably, it also includes an adhesive, which is used to adhere the capacitive touch film 4 to the back of the substrate 2.

[0036] Specifically, it also includes connectors. Multiple fixing seats 11 are provided at the back of the frame 1, and connecting plates 52 are respectively protruding outwards on the left and right ends of the light shield 5. The connecting plates 52 are assembled with the fixing seats 11 by the connectors.

[0037] Preferably, when the connector is a screw, a connecting hole is provided on the connecting plate 52 and a fixing hole is provided on the fixing seat 11, and the screw passes through the connecting plate and connects with the fixing hole.

[0038] Furthermore, it also includes screws. Multiple through holes 31 are spaced apart on the PCB board 3, and multiple mounting holes 53 are correspondingly provided on the light shield 5. The screws pass through the through holes 31 and connect to the mounting holes 53.

[0039] Preferably, the skeleton 1, the wood veneer layer, and the base lining layer are integrally formed by in-mold injection molding process.

[0040] Specifically, the material of frame 1 is plastic.

[0041] Furthermore, the bottom lining is made of non-woven fabric.

[0042] In particular, the capacitive touch film 4 is made of a transparent material.

[0043] In this embodiment, multiple light-blocking channels 51 are spaced apart on the light-blocking frame 5. Both ends of the multiple light-blocking channels 51 are open. Since the rear ends of the multiple light-blocking channels 51 are respectively set to correspond to multiple LED beads, and their front ends are respectively set to correspond to multiple hollow patterns after passing through the capacitive touch film 4 and the substrate 2, the light emitted by the multiple LED beads is blocked by the multiple light-blocking channels 51 of the light-blocking frame 5, thereby avoiding the mutual interference of the light emitted by two adjacent LED beads, thus effectively blocking light pollution and preventing the light sources from moving around. This is sufficient to meet the requirements of pattern clarity and color. In addition, since the frame 1 is made of plastic with light-transmitting effect, and the capacitive touch film 4 is also made of transparent material, the light emitted by each LED bead passes through its corresponding light-blocking channel 51, capacitive touch film 4, substrate 2, and corresponding hollow pattern in sequence before shining forward. This allows the hollow pattern to emit light, and the brightness of each hollow pattern is uniform, thereby effectively improving the user experience and effectively solving the problem of unclear clarity of the hollow pattern caused by light pollution.

[0044] More preferably, the veneer layer can be made of different types of wood veneer to improve the overall visual experience of the product and achieve a natural wood-like tactile feel. The backing layer is preferably made of non-woven fabric to improve the adhesion between the veneer layer and the substrate 2. In addition, the frame 1 is preferably made of plastic with light-transmitting properties, so that the substrate 2 has good light transmittance and allows the light emitted by the LED beads to effectively pass through the substrate 2, thereby solving the problem of the frame 1 being opaque. Of course, the frame 1, the veneer layer and the backing layer are integrally injection molded by in-mold insert injection molding process, eliminating the need for post-processing to add the veneer layer to the surface of the substrate 2 of the frame 1, thereby further improving the production efficiency of the product.

[0045] In this embodiment, the capacitive touch film 4 is made of a transparent material, which gives the capacitive touch film 4 a semi-transparent and uniform light effect. Specifically, the capacitive touch film 4 is preferably a single-point capacitive IC touch structure, which can effectively prevent light attenuation and allow the light emitted by the LED to penetrate the capacitive touch film 4, thereby making the hollow pattern clearer and the light more uniform. In addition, the capacitive touch film 4 is attached to the back of the substrate 2 with an adhesive, which is preferably made of optical adhesive.

[0046] More preferably, a housing is provided at the back of the frame 1, thereby defining a receiving cavity through the cooperation between the housing and the frame 1. The capacitive touch film 4, the light shield 5, and the PCB board 3 are all located in the receiving cavity for protection. In addition, an opening is provided in the middle of the substrate 2, which facilitates the installation of the touch interior parts with the gear knob or other structural components of the car, thereby enabling the touch interior parts to meet the installation requirements of different environments.

[0047] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
