[0027] The present invention will be further described below in conjunction with the embodiments and the drawings.

[0028] As shown in Figure 1 、 Figure 3 and Figure 4As shown in the figure, a speaker and an integrated interior door handle ambient light mainly include a door trim panel 1. An interior door handle groove 1b and a speaker sound-emitting area 1a1 are provided on the door trim panel 1. The speaker sound-emitting area 1a1 is composed of densely distributed sound-transmitting holes 1a11. The inner side of the door trim panel 1 is covered with a speaker trim panel 2 that can transmit light. An ambient light bracket 3 is installed on one side of the speaker trim panel 2 close to the interior door handle groove 1b. At least a light guide plate 4 that can emit light to both the inner and outer surfaces and at least one light source 5 for lighting the light guide plate 4 are installed on the ambient light bracket 3, that is, the light emitted by each light source 5 can light up the light guide plate 4.

[0029] Since the groove wall of the interior door handle groove 1b has a handle light-emitting surface 1b1 that can transmit light, and the inner surface of the light guide plate 4 covers the handle light-emitting surface 1b1, the light emitted from the inner surface of the lit light guide plate 4 can be introduced into the interior door handle groove 1b through the handle light-emitting surface 1b1 to light up the interior door handle groove 1b. At the same time, since the outer surface of the light guide plate 4 covers at least part of the speaker trim panel 2, the light emitted from the outer surface of the lit light guide plate 4 can direct the light to each sound-transmitting hole 1a11 facing the light guide plate 4 through the speaker trim panel 2 to light up each sound-transmitting hole 1a11 facing the light guide plate 4.

[0030] Therefore, enabling the speaker and the interior door handle to share the same set of light guide plate and light source can not only ensure the lighting effects of the handle ambient light and the speaker ambient light, but also effectively reduce the cost of arranging the handle ambient light and the speaker ambient light. At the same time, it also effectively reduces the occupation of the interior space of the door by the ambient light, greatly improving the versatility, compatibility, and assembly convenience of the ambient light.

[0031] Please refer to Figure 1 、 Figure 3 and Figure 4 , the door trim panel 1 includes a speaker panel 1a, a speaker rear cover 1d covering the rear side of the speaker panel 1a, and a handle panel 1c installed on the upper part of the speaker rear cover 1d. The speaker trim panel 2, the ambient light bracket 3, the light guide plate 4, and each light source 5 are all installed between the speaker panel 1a and the speaker rear cover 1d. Part of the speaker rear cover 1d is the front wall 1d1 of the handle groove. A part of the handle panel 1c near the lower edge is recessed to form a rear wall 1c1 of the handle groove that fits the front wall 1d1 of the handle groove. The lower part of the rear wall 1c1 of the handle groove extends downward to the inside of the front wall 1d1 of the handle groove and jointly forms the interior door handle groove 1b with the front wall 1d1 of the handle groove. The front wall 1d1 of the handle groove has a handle light-emitting surface 1b1 that can transmit light. The structure is simple and reliable, and it is easy to assemble. By installing the light guide plate 4 between the speaker trim panel 2 and the speaker rear cover 1d, since the light guide plate 4 emits light from both the inner and outer surfaces, it can light up the speaker and the interior door handle (that is, the interior door handle groove 1b and the corresponding part of the sound-transmitting holes 1a11) at the same time.

[0032] Please refer to Figure 4 , the light-emitting surface 1b1 of the buckle made of a light-transmitting plastic material and the speaker rear cover 1d made of a light-shielding plastic material are integrally formed by a two-color injection molding process, which not only ensures the light-transmitting ability of the light-emitting surface 1b1 of the buckle, but also ensures the connection strength and structural reliability between the light-emitting surface 1b1 of the buckle and the speaker rear cover 1d. In this embodiment, the light-emitting surface 1b1 of the buckle is made of transparent PC material, and the speaker rear cover 1d is made of black plastic material, which can not only ensure the light-transmitting ability of the light-emitting surface 1b1 of the buckle, but also ensure the light-shielding ability of the speaker rear cover 1d to prevent light leakage from the speaker rear cover 1d.

[0033] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 7 , the speaker interior panel 2 is made of a smoky gray semi-transparent plastic material, which can not only transmit light externally, but also cover up internal ugliness when the ambient light is turned off. The speaker panel 1a is made of a metal material, with high aesthetic appearance and enhanced overall high-class sense.

[0034] Furthermore, the speaker rear cover 1d is snap-fitted with the speaker panel 1a, and the speaker interior panel 2 and the ambient light bracket 3 are clamped between the speaker rear cover 1d and the speaker panel 1a. Specifically, the structure of the snap-fit between the speaker rear cover 1d and the speaker panel 1a also passes through the speaker interior panel 2 and the ambient light bracket 3, thereby enhancing the installation reliability of the speaker interior panel 2 and the ambient light bracket 3.

[0035] Please refer to Figure 1 , a decorative strip 6 extending along the length direction is provided at the upper edge of the speaker panel 1a, and the decorative strip 6 is snap-fitted and installed on the upper edge of the speaker rear cover 1d along the length direction, which can decorate the joint between the speaker panel 1a and the speaker rear cover 1d and enhance the overall aesthetic feeling.

[0036] Please refer to Figure 3 and Figure 6The atmosphere light bracket 3 is a box-shaped structure with an open side close to the speaker interior panel 2. The atmosphere light bracket 3 includes a light guide plate mounting groove 3a adapted to the light guide plate 4 and a light source mounting groove 3b adapted to the corresponding light source 5. The light guide plate 4 is installed in the light guide plate mounting groove 3a, and each light source 5 is installed in the corresponding light source mounting groove 3b. A bracket light-transmitting hole 3a1 adapted to the buckle hand light-emitting surface 1b1 is opened at the bottom of the light guide plate mounting groove 3a, which is opposite to the buckle hand light-emitting surface 1b1. The overall wrapped atmosphere light bracket 3 has high structural strength, which ensures the reliable installation of the light guide plate 4 and the light source 5. Then, by opening the bracket light-transmitting hole 3a1 on the light guide plate mounting groove 3a, the light emitted from the inner surface of the light guide plate 4 can pass through the bracket light-transmitting hole 3a1 and the buckle hand light-emitting surface 1b1 in turn and then enter the inner buckle hand groove 1b, thereby lighting up the inner buckle hand groove 1b.

[0037] See also Figure 3 and Figure 4 The light guide plate 4 includes a block light emitting area 4a and an upper strip light emitting area 4b and a lower strip light emitting area 4c extending outward from the same side of the block light emitting area 4a. The inner and outer surfaces of the block light emitting area 4a, the upper strip light emitting area 4b and the lower strip light emitting area 4c are all provided with diffuse reflection structures 4d. There are three light sources 5, of which the light emitting surfaces of two light sources 5 are respectively facing the side edges of the upper strip light emitting area 4b and the lower strip light emitting area 4c away from the block light emitting area 4a, and the light emitting surface of the remaining light source 5 is facing the side edge of the block light emitting area 4a away from the upper strip light emitting area 4b and the lower strip light emitting area 4c. Through the special-shaped light guide plate 4, a special shape can be lit on the speaker panel 1a, and through the arrangement of the three light sources 5, the overall light brightness and uniformity of the light guide plate 4 can be guaranteed.

[0038] See also Figures 3 - 5, an unlocking handle mounting ring 2a for mounting a door unlocking handle is integrally formed on the speaker interior panel 2. The unlocking handle mounting ring 2a is located between the block-shaped light-emitting area 4a, the upper strip-shaped light-emitting area 4b, and the lower strip-shaped light-emitting area 4c. Diffuse reflection structures 4d capable of guiding light to the unlocking handle mounting ring 2a are provided on the side edges of the block-shaped light-emitting area 4a, the upper strip-shaped light-emitting area 4b, and the lower strip-shaped light-emitting area 4c close to the unlocking handle mounting ring 2a. Therefore, through the position design of the unlocking handle mounting ring 2a and the addition of diffuse reflection structures 4d on the corresponding side edges of the block-shaped light-emitting area 4a, the upper strip-shaped light-emitting area 4b, and the lower strip-shaped light-emitting area 4c, part of the light in the light guide plate 4 can be exported through these diffuse reflection structures 4d and projected onto the unlocking handle mounting ring 2a, thereby lighting up the unlocking handle mounting ring 2a, so that a set of ambient light structure can light up three areas of the speaker, the door inner handle, and the door unlocking handle at the same time, which not only further improves the types of light effects of the door ambient light, but also further reduces the cost of arranging the ambient light for the door unlocking handle, the inner handle, and the speaker, and at the same time further reduces the occupation of the door internal space by the ambient light, and greatly improves the versatility, compatibility, and assembly convenience of the ambient light. Moreover, since the light inside the light guide plate 4 can be exported outward when encountering a sudden change (i.e., the unlocking handle mounting ring 2a formed by protrusion), a large contrast is formed with the surrounding light effects, so that the lighting characteristics of the unlocking handle mounting ring 2a can be further highlighted, the shaping characteristics of the unlocking handle can be highlighted, and a more rich and elegant interior atmosphere of the vehicle can be created.

[0039] In this embodiment, the light source 5 is a PCBA integrated with LED lamp beads or a laser light source. The advantage of using an LED light source is low cost and long service life. The advantage of using a laser light source is that it can make the light guide plate 4 brighter, thereby further improving the brightness of the ambient light for the door unlocking handle, the inner handle, and the speaker.

[0040] It should be noted that whether it is a PCBA integrated with LED lamp beads or a laser light source, it can perform rhythm and color gradient according to the music rhythm, further improving the sense of luxury of the ambient light. The diffuse reflection structure 4d can be a conventional diffuse reflection structure such as an optical pattern, a leather pattern, a frosted texture, and an optical small tooth.

[0041] Please refer to Figure 3 , Figure 4 and Figure 7 , a speaker mounting ring 2b is integrally formed on the speaker interior panel 2, and the sound generating device of the speaker is installed in the speaker mounting ring 2b.
