Description

Speaker cover decoration structure, control method, vehicle door and vehicle Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to a speaker cover decorative structure, a vehicle door and a vehicle. Background Art

[0002] As consumers' demands for personalized, humanized and intelligent car design continue to increase, car interiors have also become people's independent private spaces, which has also led to people's increasing requirements for interior environment atmosphere and interior comfort. The various forms of realizing ambient lighting effects are also an important means to enhance the sense of interior grade.

[0003] Traditional ambient lights generally have lamp shells that are directly exposed on the interior surface or are displayed through IML (In Molding Label, Chinese name: in-mold insert injection molding, whose process is very notable: the surface is a hardened transparent film, the middle is a printed pattern layer, and the back is a plastic layer. Because the ink is sandwiched in the middle, the product can prevent the surface from being scratched and resistant to friction, and can maintain bright colors for a long time and not easy to fade) for translucent display. The translucent medium of the light-guiding linear light source is directly exposed on the interior surface. The color changes of the ambient light are displayed through the dynamic changes in the color of the ambient light guide. This structural form realizes the effect of linear light source ambient light, which makes the traditional ambient light single in form, poor in appearance, hard in surface, low in comfort, and low in grade.

[0004] Summary of the Invention

[0005] To solve the above problems, the present invention proposes a speaker cover decoration structure, which abandons the traditional surface light source and IML decorative panel structure, hides the atmosphere light behind the electroplating decorative panel, and ensures the beauty of the shape. When the light is turned off, the atmosphere light is perfectly hidden in the electroplating decorative panel, and the door panel surface only presents a landscape effect; when the light is turned on, the atmosphere light appears and blends with the original landscape effect; this form of expression can create a unique atmosphere of technology and luxury, and is an important decoration for the interior of the car, especially at night, to show differences and enhance the texture of the interior; it also has a touch function. When a person touches the surface of the interior part, the capacitance of the touch flexible circuit board will change, and the touch signal will be transmitted to the PCB control circuit board; the PCB control circuit board makes corresponding actuation control according to the program; by touching the surface of the interior part, the atmosphere light can be dimmed and changed in color to create the desired atmosphere and become more technological.

[0006] The present invention provides a speaker cover decoration structure, comprising a dimming control substrate, a speaker cover fixing seat, a shielding layer, a speaker cover, a light source assembly and a speaker cover decoration frame;

[0007] The speaker cover fixing base is fixed on the dimming control substrate;

[0008] The speaker cover decorative frame is matched and fixed on the front end surface of the speaker cover fixing seat;

[0009] The speaker cover, the light source assembly and the shielding layer are sequentially sandwiched and fixed between the speaker cover decorative frame and the speaker cover fixing seat, and the light source assembly is matched and limitedly set between the circumferential outer side surface of the speaker cover and the circumferential inner side wall of the speaker cover decorative frame;

[0010] The light source assembly is electrically connected to the flexible circuit board on the dimming control substrate.

[0011] The speaker cover is snap-fitted and fixed on the front surface of the speaker cover fixing seat, and the speaker cover and the speaker cover fixing seat sandwich a shielding layer of matching shape between the two. The purpose of setting the shielding layer is to shield the structure of the speaker cover fixing seat and avoid directly seeing the structure of the speaker cover fixing seat from the grid of the speaker cover.

[0012] The speaker cover is a mesh cover as a whole, and the lower edge of the mesh cover is in the shape of a mountain. The light source component is shaped to match and is adjacent to the lower edge of the mesh cover. The speaker cover decorative frame is a frame structure as a whole, and the speaker cover decorative frame is provided with a mountain-shaped shielding portion corresponding to the position of the lower edge of the speaker cover. The light source component is snap-fitted and fixed to the inner surface of the mountain-shaped shielding portion of the speaker cover decorative frame. A gap is provided between the outer edge of the front surface of the speaker cover and the inner surface of the speaker cover decorative frame at the corresponding position, so that after the light source component receives the command to power on and light up, the light with the mountain-shaped outline can pass through the speaker cover. The gap between the speaker cover decorative frame and the ambient light is translucent outward, hiding the ambient light behind the electroplated decorative panel, ensuring the beauty of the shape. When the light is off, the ambient light is perfectly hidden in the electroplated decorative panel, and the surface of the speaker cover decorative structure only presents a landscape effect; when the light is on, the ambient light appears and merges with the original landscape effect. This form of expression can create a unique atmosphere of technology and luxury. There is no need for a separate IML decorative panel to match the surface light source ambient light, which reduces costs. It is an important decoration for showing differences and enhancing the texture of the interior of the car, especially at night.

[0013] The surface of the grid cover of the speaker cover is provided with a mountain-shaped pattern composed of grids.

[0014] The light source assembly includes an optical wire harness, an optical fiber shaped bracket and an optical wire harness terminal. The upper end face of the optical fiber shaped bracket matches the lower edge of the grid cover body adjacent to the speaker cover. The optical fiber shaped bracket is correspondingly snap-fitted and fixed to the upper inner surface of the mountain-shaped shielding portion of the speaker cover decorative frame. One end of the optical wire harness is fixedly connected to the optical wire harness terminal. The optical wire harness terminal is electrically connected to the flexible circuit board. The optical wire harness is fixed on the optical fiber shaped bracket. The optical wire harness terminal is snap-fitted and fixed to the inner surface of the speaker cover decorative frame.

[0015] There is a missing portion on the upper right part of the dimming control substrate, and the upper end and right end of the dimming control substrate are respectively provided with bent edges inward. The speaker cover fixing seat is fixed on the bent edge at the missing portion of the dimming control substrate, and a speaker sound hole is provided on the speaker cover fixing seat corresponding to the position of the speaker cover.

[0016] The dimming control substrate also includes a flexible circuit board, an inner translucent PC frame, an outer translucent PC frame and translucent leather; the front and rear surfaces of the flexible circuit board are respectively injection-molded with the outer translucent PC frame and the inner translucent PC frame; the translucent leather is covered and fixed on the outer surface of the outer translucent PC frame. The present invention also has a touch function. When a person touches the surface of the interior decoration part, the capacitance of the touch flexible circuit board will change, and the touch signal will be transmitted to the PCB control circuit board; the PCB control circuit board makes corresponding actuation control according to the program; by touching the surface of the interior decoration part, the ambient light can be dimmed and changed in color to create the desired atmosphere and become more technological.

[0017] A control method for a loudspeaker cover decorative structure is provided, wherein the control method is implemented using the loudspeaker cover decorative structure, specifically comprising:

[0018] When you touch the translucent leather, the touch signal causes the capacitance of the flexible circuit board to change. The capacitance change signal is transmitted to the PCB control circuit board. The PCB control circuit board controls the light source component to adjust the color of the ambient light according to the number of touches.

[0019] A vehicle door comprises a vehicle door panel and a speaker, and also comprises the speaker cover decorative structure. The speaker cover decorative structure is fixed on the vehicle door panel, and the speaker is fixed to the inner surface of the speaker cover fixing seat at the speaker sound hole position.
