DETAILED DESCRIPTION

[0045] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0046] Embodiment 1:

[0047] Since the existing direct-type ambient light of the front panel usually embeds the ambient light bracket (ambient light light strip) into the front panel trim, there is a problem of imaging the ambient light on the front windshield, and there is also a problem of poor control of the gap and surface difference between the light strip and the surrounding parts.

[0048] Based on this, this embodiment provides a direct-lighting atmosphere light for the front of a car dashboard, such as Figure 1 and Figure 2 As shown, it includes a front enclosure upper trim panel assembly, a front enclosure lower trim panel 7, an ambient light bracket 4, an ambient light guide 6, an ambient light lamp head 8, etc. The ambient light bracket 4, the ambient light guide 6 and the ambient light lamp head 8 are installed between the front enclosure upper trim panel assembly and the front enclosure lower trim panel 7; wherein, the front enclosure upper trim panel assembly includes a front enclosure upper trim panel frame 2 and a front enclosure upper trim panel skin 1 arranged on the outer surface of the front enclosure upper trim panel frame 2.

[0049] like Figure 3 and Figure 4 As shown, the front upper panel skin 1 is covered on the outside of the front upper panel frame 2, and the end of the front upper panel skin 1 exceeds the end of the front upper panel frame 2 by a certain length, completely covering the front upper panel frame 2. The cross-sectional shape of the main part of the ambient light bracket 4 is inverted hook shape, so that the ambient light guide 6 is installed in the hook-shaped area formed by the main part of the ambient light bracket 4.

[0050] The atmosphere light bracket 4 is lower than the front panel assembly by a surface difference value, so that the front panel assembly forms a brim structure relative to the atmosphere light bracket 4. The upward light guided by the atmosphere light bracket 4 is blocked by the front panel assembly, and the light will not shine on the front windshield, thereby avoiding the front windshield imaging problem; at the same time, a direct linear surround atmosphere light effect can be achieved on the front panel of the instrument panel, enhancing the technological and luxurious lighting effects of the interior atmosphere lights.

[0051] In this embodiment, the face difference value is 3 mm. Of course, this value can also be adjusted according to actual requirements.

[0052] like Fig.13 As shown, the top of the ambient light bracket 4 is provided with a first limiting rib 15, and the front upper trim frame 2 is provided with a first limiting groove 10. The first limiting rib 15 is plugged and matched with the first limiting groove 10 to control the position of the ambient light bracket 4 in the X direction and ensure the surface difference between the ambient light bracket 4 and the front upper trim assembly. Since the linear length of the front trim assembly is about 1700mm, the length is relatively long, in order to make the entire ambient light bracket 4 and the front upper trim assembly have a consistent surface difference value, as shown in FIG. Figure 7 and Figure 8 As shown, a plurality of first limiting ribs 15 are arranged at a certain distance along the length direction of the atmosphere lamp bracket 4; Figure 5 and Figure 6As shown, a plurality of first limiting grooves 10 are provided in the length direction of the front enclosure upper trim frame 2, and the first limiting grooves 10 correspond to the first limiting ribs 15 one by one.

[0053] The number of the first limiting ribs 15 and the spacing between adjacent first limiting ribs 15 can be designed according to actual installation requirements. For example, 31 first limiting ribs 15 are provided, and the spacing between adjacent first limiting ribs 15 is about 33 mm.

[0054] A plurality of first welding ribs 12 are distributed in the length direction of the front panel frame 2, for example, 12 first welding ribs 12 are set; the ambient light bracket 4 is provided with a first welding hole 18 corresponding to the first welding rib 12, the first welding rib 12 is inserted into the first welding hole 18, and the first welding rib 12 is melted by an ultrasonic welding head to weld the ambient light bracket 4 and the front panel frame 2 together; and a standardized welding process is required to ensure the appearance gap between the ambient light bracket 4 and the front panel frame 2.

[0055] The surface 1 of the front panel trim is a covering part. In the present embodiment, the surface 1 of the front panel trim is made of PVC material, and the ambient light bracket 4 is made of PC material. Since the ambient light bracket 4 is in direct contact with the surface 1 of the front panel trim, some special process treatments are required after production and before assembly, such as annealing the ambient light bracket 4, or spraying paint on the surface of the ambient light bracket 4 to prevent direct contact between the PVC material and the PC material.

[0056] In addition, due to the materials of the ambient light bracket 4 and the front panel assembly, friction noise is inevitable between the first limiting rib 15 and the second limiting groove 20. Therefore, a felt 5 is added between the first limiting rib 15 and the second limiting groove 20 to prevent the noise and improve the NVH performance of the whole vehicle.

[0057] The ambient light bracket 4 also determines the position of the lower front panel 7. If the lower front panel 7 is too close to the rear of the vehicle, the overlap between the ambient light bracket 4 and the lower front panel 7 is small, which will cause light leakage and matching problems; if the lower front panel 7 is too close to the front of the vehicle, the ambient light bracket 4 will be exposed to the lower front panel 7, causing scratching problems and appearance problems. The matching mode between the lower front panel 7 and the ambient light bracket 4 of this embodiment has a stable surface difference and gap, which is specifically achieved through the following structure:

[0058] like Fig.14 As shown, the lower side of the ambient light bracket 4 is provided with a second limiting rib 19, the second limiting rib 19 is arranged on the hook-shaped hook head part of the ambient light bracket 4, and is provided on the front side of the ambient light guide 6; the front lower trim panel 7 is provided with a second limiting groove 20, the second limiting rib 19 is plugged into and matched with the second limiting groove 20 to limit the position of the front lower trim panel 7 in the X direction, thereby ensuring the surface difference between the ambient light bracket 4 and the front lower trim panel 7.

[0059] Similarly, if Figure 9-12As shown, due to the long linear length of the front panel assembly, a plurality of second limiting ribs 19 are provided along the length direction of the ambient light bracket 4, and a plurality of second limiting grooves 20 are provided along the length direction of the front panel lower panel 7, and the second limiting grooves 20 correspond to the second limiting ribs 19 one by one, so that the entire ambient light bracket 4 and the front panel lower panel 7 have consistent surface difference values. The number of the second limiting ribs 19 and the second limiting grooves 20 and the spacing between adjacent second limiting ribs 19 and second limiting grooves 20 are selected according to actual requirements, for example: 30 second limiting ribs 19 and second limiting grooves 20 are provided, and the spacing between adjacent second limiting ribs 19 and adjacent second limiting grooves 20 is about 40 mm.

[0060] In this embodiment, the front lower trim 7 is made of PP+EPDM-T20. Similarly, in order to avoid the risk of friction noise between the second limiting rib 19 and the second limiting groove 20, a felt 5 is reserved between the second limiting rib 19 and the second limiting groove 20; the felt 5 can be retained or removed later according to the noise situation.

[0061] The ambient light bracket 4 is also provided with a second welding rib 21, which is located at the rear side of the ambient light guide 6 and cooperates with the second welding hole 23 provided on the front lower trim 7. A plurality of second welding ribs 21 are provided along the length direction of the ambient light bracket 4, and the number of the second welding holes 23 is the same as the number of the second welding ribs 21. In order to ensure the connection strength between the ambient light bracket 4 and the front lower trim 7, the number of the second welding ribs 21 is greater than the number of the first welding ribs 12; in this embodiment, 25 second welding ribs 21 are provided.

[0062] The ambient light bracket 4 is provided with a plurality of first mounting holes 16, the lower front panel 7 is provided with a plurality of second mounting holes 22, and the upper front panel frame 2 is provided with a plurality of Boss pillars 9; Fig.15 As shown, the first mounting hole 16 and the second mounting hole 22 both pass through the Boss column 9 and are then fixed by self-tapping screws 3 to connect the front enclosure upper panel frame 2, the ambient light bracket 4 and the front enclosure lower panel 7 together.

[0063] It should be noted that the “first” and “second” in this embodiment are distinguished for the convenience of description and do not impose any limitation on specific structures such as the limiting ribs and the mounting holes.

[0064] In this embodiment, the atmosphere light bracket 4 is lower than the front enclosure upper trim panel assembly by a surface difference value, and the atmosphere light bracket 4 is plugged into the first limiting rib 15 and the first limiting groove 10, and the second limiting rib 19 and the second limiting groove 20 to achieve the limitation of the atmosphere light bracket 4 and the front enclosure lower trim panel 7 in the X direction, and then the front enclosure upper trim panel frame 2, the atmosphere light bracket 4 and the front enclosure lower trim panel 7 are assembled together in combination with the self-tapping screw 3 and the Boss column 9 connection structure; this not only enhances the lighting effect of the interior atmosphere light with a sense of technology and luxury, but also effectively avoids driving safety problems caused by light reflection on the glass. At the same time, due to the specific connection structure and limiting structure formed between the front enclosure upper trim panel assembly, the atmosphere light bracket 4 and the front enclosure lower trim panel 7, a good gap and surface difference quality are obtained between the three.

[0065] Embodiment 2:

[0066] The present embodiment provides an assembly method for a direct-beam atmosphere light on a front panel of a car instrument panel. Based on the direct-beam atmosphere light structure described in Embodiment 1, first, the atmosphere light guide 6 is fixed to the atmosphere light bracket 4 through a clamping structure. After the atmosphere light bracket 4 is plugged into the front panel upper trim frame 2, it is welded and fixed to the front panel upper trim frame 2 through welding ribs; then, the front panel lower trim 7 and the atmosphere light bracket 4 are welded and fixed after being plugged in, and then the front panel lower trim 7, the atmosphere light bracket 4, and the front panel upper trim frame 2 are connected together from the back with self-tapping screws 3 to form a front panel trim assembly; finally, the front panel trim assembly is assembled to the instrument panel.

[0067] The assembly process of the front cowl upper trim assembly and the ambient light bracket 4 is as follows:

[0068] First, pre-install the ambient light bracket 4 onto the front panel frame 2, and the first limiting ribs 15 of the ambient light bracket 4 are plugged into the first limiting grooves 10 at the corresponding positions of the front panel frame 2; after the pre-installation is completed, the first welding ribs 12 on the front panel frame 2 are melted by an ultrasonic welding head, so that the ambient light bracket 4 and the front panel frame 2 are welded together.

[0069] The assembly process of the front wall lower trim panel 7 and the ambient light bracket 4 is as follows:

[0070] First, pre-install the front lower trim panel 7 onto the ambient light bracket 4, and the second limiting ribs 19 on the ambient light bracket 4 are plugged into the second limiting grooves 20 at the corresponding positions of the front lower trim panel 7; after the pre-installation is completed, the second welding ribs 21 are melted by an ultrasonic welding head to weld the front lower trim panel 7 and the ambient light bracket 4 together.

[0071] Through the above-mentioned assembly process, this embodiment can achieve a stable connection between the front panel upper trim assembly, the ambient light bracket 4 and the front panel lower trim 7, and can ensure good gap and surface difference quality.

[0072] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
