Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to a vehicle-mounted surface decorative plate, a preparation method and an automobile. Background Art

[0002] With the continuous development of artificial intelligence and Internet of Vehicles technology, future cars will develop towards human-computer interaction. Against this background, smart car application technology will become increasingly mature and perfect, and the rigid demand for in-vehicle human-computer interface will also be further enhanced.

[0003] The touch screen body used for human-computer interaction is usually set on the dashboard on the side of the car's steering wheel, and the touch screen body has high requirements for light transmittance. In order to meet the touch screen body's requirements for light transmittance, traditional dashboards usually use a dashboard skeleton made of a large area of ​​light-transmitting material. The various structures in the touch screen body (such as circuit boards, light sources, ink printing layers with pattern logos, and capacitor film layers, etc.) are set on the backlight surface of the skeleton, and finally form the entire vehicle-mounted surface trim. The pattern logo in the touch screen body will be transmitted on the surface of the transparent skeleton when the light source is working, thereby facilitating user touch operations. This skeleton using a large area of ​​light-transmitting material is expensive, and when disassembling and repairing the components in the touch screen body, the entire skeleton needs to be removed first, which makes disassembly and assembly inconvenient. Summary of the Invention

[0004] The present invention aims to solve the problem that the cost of automobile surface decorative panels is high and the touch screen body inside the panels is inconvenient to disassemble and assemble.

[0005] In order to solve the above problems, the present invention provides a vehicle-mounted surface trim panel, including a covering frame, a translucent leather layer and a touch screen body. The covering frame is provided with a first notch groove, and the touch screen body is detachably connected to the first notch groove. The translucent leather layer is provided on the surface of the covering frame to cover the covering frame and the touch screen body.

[0006] The vehicle surface trim provided by the present invention has the following advantages over the prior art:

[0007] The covering frame can be made of a non-transparent material, with a first notch provided in the covering frame. The touchscreen body can be installed in the first notch. The area of ​​transparent material required in the touchscreen body is less than or equal to the area of ​​the first notch, significantly reducing the use of transparent material and the cost of the entire vehicle surface trim. The touchscreen body is detachably connected to the covering frame for installation in the first notch. When the touchscreen body needs to be repaired, the entire covering frame does not need to be disassembled; only the touchscreen body at the first notch needs to be removed, reducing assembly and disassembly costs and increasing convenience. During touch operation, the pattern logo on the touchscreen body appears on the surface of the translucent leather layer on the surface of the vehicle surface trim. By touching the pattern logo on the translucent leather layer, the corresponding vehicle function can be controlled, ensuring normal operation of human-computer interaction.

[0008] Furthermore, the touch screen body includes a light source assembly, a transparent panel layer, a capacitive touch film layer and an ink layer. The transparent panel layer and the capacitive touch film layer are bonded to form a control unit assembly. The control unit assembly is arranged on the light path of the light source assembly. The ink layer is arranged between the control unit assembly and the translucent leather layer. The ink layer has at least one pattern logo.

[0009] Furthermore, the transparent panel layer and the capacitive touch film layer are sequentially arranged along the direction of the light source assembly.

[0010] Furthermore, the vehicle-mounted surface trim panel further includes a base fabric layer, which is arranged on the backlight side of the translucent leather layer, and the ink layer is arranged between the base fabric layer and the translucent leather layer.

[0011] Furthermore, the vehicle surface trim also includes a base fabric layer, which is arranged on the backlight side of the translucent leather layer, and the ink layer is arranged on the surface of the capacitive touch film layer, and the base fabric layer has a hollow structure matching the pattern logo.

[0012] Furthermore, the light source assembly includes a lamp panel and a shading plate, wherein the shading plate is connected to the lamp panel and is used to constrain the light emitted by the light-emitting element on the lamp panel.

[0013] Furthermore, the light source assembly further includes a fixing bracket, the light panel or the sunshade is connected to the fixing bracket, and the fixing bracket is detachably connected to the covering frame.

[0014] Furthermore, the vehicle surface trim panel also includes a soft trigger bubble layer, which is arranged between the covering frame and the translucent leather layer, and the soft trigger bubble layer is provided with a second notch groove corresponding to the first notch groove.

[0015] The present invention also provides an automobile, comprising the above-mentioned vehicle surface trim.

[0016] Since the technical improvements and beneficial effects of the automobile are the same as those of the vehicle-mounted surface trim, the automobile will not be described in detail.

[0017] The present invention also provides a method for preparing a vehicle-mounted surface decorative panel, comprising: opening a first notch groove on a covering frame, installing a touch screen body at the first notch groove of the covering frame, and attaching a translucent leather layer to the surface of the covering frame to cover the covering frame and the touch screen body.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0027] See also Figures 1 to 3A vehicle surface trim panel according to an embodiment of the present invention includes a covering frame 04, a translucent leather layer 01 and a touch screen body. The covering frame 04 is provided with a first notch groove 041. The touch screen body is detachably connected to the first notch groove 041. The translucent leather layer 01 is provided on the surface of the covering frame 04 to cover the covering frame 04 and the touch screen body.

[0028] In this embodiment, the covering frame 04 can be made of non-transparent material, and a first notch is set on the covering frame 04. The touch screen body can be installed at the first notch. The area required for the transparent material involved in the touch screen body is less than or equal to the area of ​​the first notch, which greatly reduces the use of transparent material and reduces the cost of the entire vehicle surface trim. The touch screen body is detachably connected to the covering frame 04 to be installed at the first notch. When the touch screen body needs to be repaired, there is no need to disassemble the entire covering frame 04. Only the touch screen body at the first notch needs to be disassembled. It reduces the disassembly and assembly cost and is more convenient. During touch operation, the pattern logo in the touch screen body is presented on the surface of the translucent leather layer 01 on the surface of the vehicle surface trim. The corresponding function control of the vehicle can be completed by touching the pattern logo on the surface of the translucent leather layer 01 by hand.

[0029] Optionally, the material of the translucent leather layer 01 can be at least one of soft materials such as polyurethane (PU), polyvinyl chloride (PVC) and fabric. While meeting the light transmittance requirements, since the translucent leather layer 01 is the outermost layer of the vehicle surface trim, it fits better with other interior decorations inside the vehicle, thereby improving the appearance and beauty of the vehicle surface trim and giving users a good experience both in terms of perception and touch.

[0030] The touch screen body and the covering frame 04 may be connected in a detachable manner such as a snap connection or a screw connection, and the covering frame 04 may be a dashboard frame.

[0031] See also Figures 1 to 3 Optionally, the touch screen body includes a light source assembly, a transparent panel layer 03, a capacitive touch film layer 02 and an ink layer. The transparent panel layer 03 and the capacitive touch film layer 02 are laminated to form a control unit assembly. The control unit assembly is arranged on the light path of the light source assembly. The ink layer is arranged between the control unit assembly and the translucent leather layer 01. The ink layer has at least one pattern logo.

[0032] In this embodiment, the touch screen body is a capacitive touch screen, and the translucent leather layer 01 is non-conductive. The dielectric constant of the material used for the translucent leather layer 01 is greater than 3 and the thickness is less than 3 mm, ensuring that the capacitive touch screen has good sensitivity when touched by a finger. The surface texture depth difference of the translucent leather layer 01 is less than 50 μm, which solves the problem of inconsistent pattern brightness caused by inconsistent thickness affecting user perception.

[0033] In this embodiment, the transparent panel layer 03 may be made of transparent plastic material, and provides a mounting carrier for the capacitive touch film layer 02 . The transparent panel layer 03 and the capacitive touch film layer 02 are bonded and fixed together to form a control unit assembly.

[0034] In this embodiment, the structure from the light source assembly to the translucent leather layer 01, the outermost layer of the vehicle's surface trim, is composed, in order: the light source assembly, the control unit assembly, the ink layer, and finally the translucent leather layer 01. When a finger approaches the translucent leather layer 01 (e.g., within 40 mm of the surface), the vehicle's sensor detects it, causing the light source assembly to emit light. This light ultimately transmits the various pattern markings in the ink layer onto the surface of the translucent leather layer 01. The finger can then touch the corresponding pattern markings on the translucent leather layer 01, thereby controlling the corresponding vehicle function, such as turning on the air conditioning.

[0035] It should be noted that the principle of the capacitive touch screen is a relatively mature existing technology, so this article will not elaborate on the principle that the corresponding operation function can be realized by touching the translucent leather layer 01 with a finger.

[0036] In this embodiment, the light source assembly can be first connected to the covering frame 04 by snap-fitting or screwing, and then the control unit assembly can be connected to the covering frame 04 by snap-fitting or screwing.

[0037] See also Figure 4 Optionally, a light-shielding edge layer 09 is provided at the edge of the transparent panel layer 03 to prevent light from leaking from the edge of the transparent panel layer 03 when the light passes through the transparent panel layer 03 .

[0038] Optionally, the transparent panel layer 03 and the capacitive touch film layer 02 are sequentially arranged away from the light source assembly.

[0039] In this embodiment, the order from the light source assembly to the translucent leather layer 01 is the light source assembly, transparent panel layer 03, capacitive touch film layer 02, ink layer, and translucent leather layer 01. By placing the capacitive touch film layer 02 on the surface of the transparent panel (i.e., the side away from the light source assembly), the distance between the capacitive touch film layer 02 and the leather surface is closer, allowing the capacitive touch film layer 02 to accurately respond to changes in capacitance when a finger touches the translucent leather layer 01, thereby ensuring touch sensitivity.

[0040] Optionally, the vehicle-mounted surface trim further includes a base fabric layer, which is arranged on the backlight side of the translucent leather layer 01 , and the ink layer is arranged between the base fabric layer and the translucent leather layer 01 .

[0041] In this embodiment, the base fabric layer is arranged on the backlight surface of the translucent leather layer 01 (the side close to the light source assembly), and the base fabric layer and the translucent leather layer 01 and the ink layer located between the two constitute the translucent composite leather. By setting the base fabric layer, the translucent composite leather has better ductility when it is wrapped around the wrapping skeleton 04, and can achieve good wrapping. Secondly, the translucent composite leather also has better toughness, which meets the sewing requirements of automobile interiors.

[0042] In this embodiment, the components from the light source assembly to the translucent leather layer 01 are, in order, the light source assembly, the transparent panel layer 03, the capacitive touch film layer 02, the base fabric layer, the ink layer, and finally the translucent leather layer 01. Compared to conventional ink layers, where the patterned markings suffer from poor clarity after diffuse transmission through multiple layers of translucent media, this embodiment, by placing the ink layer between the base fabric layer and the translucent leather layer 01, allows the patterned markings on the ink layer to be displayed on the surface of the translucent leather layer 01 after diffuse transmission through only one layer of translucent media (i.e., the translucent leather layer 01), resulting in high clarity.

[0043] Optionally, the vehicle surface trim further includes a base fabric layer, which is arranged on the backlight surface of the translucent leather layer 01, and the ink layer is arranged on the surface of the capacitive touch film layer 02, and the base fabric layer has a hollow structure matching the pattern logo.

[0044] In this embodiment, unlike the "ink layer disposed between the base fabric layer and the translucent leather layer 01", the ink layer can also be disposed on the surface of the capacitive touch film layer 02, and a hollow structure matching the pattern logo is provided on the base fabric layer. In this case, the pattern logo of the ink layer only needs to pass through a layer of translucent medium (i.e., diffuse transmission of the translucent leather layer 01) to be displayed on the surface of the translucent leather layer 01. The base fabric layer and the translucent leather layer 01 constitute a translucent composite leather, and a transparent layer matching the shape of the hollow structure can be provided at the hollow structure of the base fabric layer, thereby ensuring the smooth appearance quality of the surface (backlight side) of the translucent composite leather, while also ensuring the light transmittance brightness and clarity of the pattern logo.

[0045] See also Figure 1 and Figure 3 Optionally, the light source assembly includes a lamp board 08 and a shading plate 06 , wherein the shading plate 06 is connected to the lamp board 08 , and the shading plate 06 is used to constrain the light emitted by the light-emitting parts on the lamp board 08 .

[0046] In this embodiment, light board 08 can be a circuit board with LED lights, where the LED lights are the aforementioned light-emitting components. As previously described, when a finger approaches translucent leather layer 01, the car's sensor detects this, and the circuit board controls the LED lights to emit light. This light ultimately transmits the various patterns and markings in the ink layer onto the surface of translucent leather layer 01. The finger can then touch the corresponding pattern and marking on the translucent leather layer 01, and the circuit board controls the corresponding car function, such as turning on the air conditioning.

[0047] In this embodiment, the shading plate 06 separates the multiple LED lights on the light board 08 from each other independently. By constraining the light emitted by the LED lights, the light from each LED light is concentrated on the corresponding pattern logo, ensuring the utilization rate of light and improving the transmittance of light passing through each transparent medium.

[0048] See also Figure 1 and Figure 3 Optionally, the light source assembly further includes a fixing bracket 07 , the LED light board 08 or the sunshade 06 is connected to the fixing bracket 07 , and the fixing bracket 07 is detachably connected to the covering frame 04 .

[0049] In this embodiment, as mentioned above, the covering frame 04 can be an instrument panel frame, and the overall shape is irregular, and it is not a flat structure, while the light board 08 is a circuit board, which is a plate-like structure and is inconvenient to be directly connected to the covering frame 04. Therefore, it is connected to the covering frame 04 through the fixed bracket 07, thereby realizing the connection between the light source assembly and the covering frame 04, which is easier to connect and the connection strength can also be guaranteed.

[0050] See also Figure 1 and Figure 5 Optionally, the vehicle surface trim further includes a soft trigger bubble layer 05 , which is disposed between the covering frame 04 and the translucent leather layer 01 , and the soft trigger bubble layer 05 is provided with a second notch groove 051 corresponding to the first notch groove 041 .

[0051] In this embodiment, a non-transparent soft trigger bubble layer 05 is provided between the non-touch button area (the area other than the first notch 041 ) of the translucent leather layer 01 and the covering frame 04 . While ensuring timely contact and feedback of the touch buttons of the translucent leather layer 01 in the main area of ​​the touch screen, it also addresses the customer's need for a soft touch in the non-touch button area, providing a stronger user experience.

[0052] Another embodiment of the present invention provides an automobile, comprising the vehicle surface trim panel as described above.

[0053] Since the technical improvements and beneficial effects of the automobile are the same as those of the vehicle-mounted surface trim, the automobile will not be described in detail.

[0054] Another embodiment of the present invention also provides a method for preparing a vehicle-mounted surface decorative panel, including: opening a first notch groove 041 on a covering frame 04, installing a touch screen body at the first notch groove 041 of the covering frame 04, and attaching a translucent leather layer 01 to the surface of the covering frame 04 to cover the covering frame 04 and the touch screen body.

[0055] Specifically, the touch screen body is installed at the first notch groove 041 of the covering frame 04, including: snapping the light shielding plate 06 and the light board 08 and assembling them on the fixed bracket 07 to form a light source assembly; bonding the capacitive touch film layer 02 to the surface of the transparent panel layer 03 to form a control unit assembly; and installing the light source assembly and the control unit assembly at the first notch groove 041 respectively.

[0056] Specifically, the translucent leather layer 01 is attached to the surface of the covering skeleton 04 to cover the covering skeleton 04 and the touch screen body, including: bonding the soft trigger bubble layer 05 to the surface of the covering skeleton 04, and making the second notch 051 of the soft trigger bubble layer 05 correspond to the first notch 041 of the covering skeleton 04; printing the ink layer on the backlight surface of the translucent leather layer 01, and then pressing the base fabric layer on the backlight surface of the translucent leather layer 01 printed with the ink layer to form a translucent composite leather, and bonding and covering the translucent composite leather on the surface of the soft trigger bubble layer 05 and covering the first notch 041.

[0057] Specifically, bonding the capacitive touch film layer 02 to the surface of the transparent panel layer 03 includes: bonding or spraying an optical-grade adhesive on the transparent panel layer 03, heating the capacitive touch film layer 02 in a heating box for 2-3 minutes to activate the adhesive, and then bonding the capacitive touch film layer 02 to the surface of the transparent panel layer 03. The heating temperature can be 85°C.

[0058] Specifically, the bonding method for the soft trigger bubble layer 05 and the covering frame 04 can also be the same as the bonding method for the capacitive touch film layer 02 to the transparent panel layer 03. The same method can be used to bond the translucent composite leather to the soft trigger bubble layer 05. This connection method can improve the yield rate while also reducing manufacturing costs. The adhesive can be an optical-grade solvent-based or water-based glue. The adhesive can also be double-sided tape, which does not require heating in a heating chamber.

[0059] It should be noted that the terms "mounted," "connected," and "connected" in the specification and claims of the present invention and the accompanying drawings should be interpreted broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0060] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present invention.
