Description

Technical Field

[0001] This utility model relates to the field of vehicle trim parts, and in particular to a vehicle trim part. Background Technology

[0002] To enrich vehicle functionality, existing technologies employ methods such as creating light-transmitting holes in vehicle trim and integrating light groups on the back of the trim, allowing the light groups to form corresponding patterns based on the distribution of the light-transmitting holes. For example, Chinese patent document CN112172702A discloses a luminous trim panel for the rear corner window frame of an automobile, which forms corresponding patterns by creating light-transmitting holes in the rear corner window frame and integrating a light-emitting module.

[0003] However, in order to achieve light transmission, the shape of the light-transmitting hole will be displayed even when the light-emitting module is not emitting light, which affects the aesthetics of the ornament. Furthermore, existing light-emitting ornaments can only form corresponding patterns according to the pre-set light emission rules, resulting in poor functionality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a vehicle trim piece that improves the aesthetics of the trim piece.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A vehicle trim piece includes a trim piece body and a light-emitting module. One side of the trim piece body has a display area with a light-transmitting hole. The light-transmitting hole is filled with a light guide. The light-emitting module is disposed on the other side of the trim piece body so that light passes through the light guide and is emitted. The vehicle trim piece also includes a concealing layer with the same color as the surface of the trim piece body.

[0007] The concealing layer is applied to at least the display area of ​​the decorative component body, and the light generated by the light-emitting module can penetrate the concealing layer.

[0008] Furthermore, the thickness of the concealment layer is less than 15 μm.

[0009] Furthermore, a plurality of light-transmitting holes are provided in the display area, and the light-transmitting holes are evenly distributed in the display area.

[0010] Furthermore, the display area has functional areas, and the concealing layer covers the portion of the display area excluding the functional areas.

[0011] Furthermore, a sensor is provided in the area corresponding to the functional area of ​​the light-emitting module, and the sensor is used to electrically connect to the vehicle central control and the light-emitting module respectively.

[0012] Furthermore, the functional area is provided in at least two forms.

[0013] Furthermore, a mounting groove is provided on the other side of the decorative component body, and the light-emitting module is embedded in the mounting groove;

[0014] The depth of the mounting groove is greater than the depth of the light-transmitting hole.

[0015] Furthermore, a gravity sensor is also integrated on the other side of the body of the ornament;

[0016] The gravity sensor is electrically connected to the light-emitting module so that the light-emitting module forms different patterns when the position of the ornament body changes.

[0017] Furthermore, the other side of the trim body is provided with a snap-fit ​​assembly for connection with a vehicle.

[0018] Furthermore, the light-emitting module is detachably connected to the main body of the decorative piece.

[0019] The beneficial effects of this invention are as follows: By applying a concealing layer to one side of the trim body, the display area is hidden when the light-emitting module is not emitting light, ensuring the integrated appearance of the trim body and improving aesthetics. Since the concealing layer is translucent, when the light-emitting module is emitting light, the pattern formed by the module will propagate outward through the corresponding light-transmitting holes, thus forming a graphic image in the display area. This invention ensures that the vehicle trim has a display function while concealing the display area when no pattern is needed, achieving an integrated appearance and improving the aesthetics of the vehicle trim.

[0031] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0032] Please refer to Figures 1-7 A vehicle trim piece includes a trim piece body 1 and a light-emitting module 2. The trim piece body 1 has a display area 11 on one side, and the display area 11 has a light-transmitting hole 12. The light-transmitting hole 12 is filled with a light guide 13. The light-emitting module 2 is disposed on the other side of the trim piece body 1 so that light passes through the light guide 13 and is emitted. The vehicle trim piece also includes a concealing layer 3 with the same color as the surface of the trim piece body 1. The concealing layer 3 is at least coated on the display area 11 of the trim piece body 1, and the light generated by the light-emitting module 2 can penetrate the concealing layer 3.

[0033] It is understandable that by applying a concealing layer 3 to one side of the trim body 1, the display area 11 is concealed when the light-emitting module 2 is not emitting light, ensuring the integrated appearance of the trim body 1 and improving aesthetics. Since the concealing layer 3 is translucent, when the light-emitting module 2 is emitting light, the pattern formed by the light-emitting module 2 will propagate outward through the corresponding light-transmitting holes 12, thus forming a graphic image in the display area 11. This invention ensures that the vehicle trim has a display function while concealing the display area 11 when no pattern is needed, achieving an integrated appearance and improving the aesthetics of the vehicle trim.

[0034] In some embodiments, the light-emitting module 2 includes a light-emitting element 21 and a control circuit board 22; the light-emitting element 21 is integrated into the side of the control circuit board 22 facing the decorative body 1. Further, the light-emitting module 2 also includes a housing 23; the control circuit board 22 is embedded in the housing 23, while the light-emitting element 21 is disposed on one side of the housing 23, and the housing 23 is snapped into the decorative body 1.

[0035] In some embodiments, the thickness of the concealment layer 3 is less than 15 μm. Excessive thickness of the concealment layer 3 would reduce light transmittance and affect the pattern formation effect. If the thickness of the shielding layer is too small, it would be unable to cover the light-transmitting holes 12 in the display area 11. Therefore, optionally, the thickness of the concealment layer 3 is 8 μm to 12 μm; preferably, the thickness of the concealment layer 3 is 8 μm, 9 μm, 10 μm, 11 μm, or 12 μm. Further, the concealment layer 3 is made by mixing semi-transparent ink with silver powder, and the silver powder accounts for 3% to 7% of the total mass of all components.

[0036] In some embodiments, a plurality of light-transmitting holes 12 are provided in the display area 11. The light-transmitting holes 12 are evenly distributed in the display area 11. Furthermore, the light-transmitting holes 12 should cover the display area 11 so that the displayed graphics can depend on the pattern generated by the light-emitting module 2, which is more flexible, more variable in pattern, and more abundant in displayable patterns.

[0037] In some embodiments, the display area 11 has functional areas 4, and the concealed layer 3 covers the portion of the display area 11 excluding the functional areas 4. Further, at least two functional areas 4 are provided, and each functional area 4 corresponds to a different function, with different graphics for each functional area 4. The provision of functional areas 4 enriches the functionality of the vehicle trim, enabling it to have control functions in addition to display functions, thereby improving usability.

[0038] In some embodiments, a sensor 5 is provided in the area corresponding to the functional area 4 of the light-emitting module 2. The sensor 5 is used to electrically connect to the vehicle central control and the light-emitting module 2, respectively. Accordingly, the number of sensors 5 depends on the number of functional areas 4. The sensor 5 can be a touch sensor or a pressure sensor. When the sensor 5 is a touch sensor, it should be located on the side of the control circuit board 22 facing the trim body 1. When the sensor 5 is a pressure sensor, it can be located on either side of the control circuit board 22.

[0039] In some embodiments, a mounting groove 14 is provided on the other side of the decorative body 1, and the light-emitting module 2 is embedded in the mounting groove 14; the depth of the mounting groove 14 is greater than the depth of the light-transmitting hole 12. The mounting groove 14 is provided to limit the light-emitting module 2 and reduce light loss, so that the light emitted can directly pass through the light-transmitting hole 12 and propagate outward, ensuring the light-emitting effect.

[0040] In some embodiments, a gravity sensor 6 is also integrated on the other side of the ornament body 1; the gravity sensor 6 is electrically connected to the light-emitting module 2 so that the light-emitting module 2 forms different patterns when the position of the ornament body 1 changes. The gravity sensor 6 is configured to control the light-emitting component to change the display direction or content of the pattern when the ornament body 1 is rotated or flipped, so as to adapt to different usage scenarios.

[0041] In some embodiments, a snap-fit ​​component 7 for connecting to a vehicle is provided on the other side of the trim body 1. The snap-fit ​​component 7 facilitates a detachable connection between the trim body 1 and the vehicle.

[0042] In some embodiments, the light-emitting module 2 is detachably connected to the decorative body 1, which facilitates the disassembly and installation of the light-emitting module 2 and reduces the difficulty of disassembly and installation.
