The advantages of the invention are explained in detail below with reference to the drawings and the embodiments.

With respect to the coordinate system shown in the figures, direction x is defined as the longitudinal extension direction of the atmosphere light trim, direction y is defined as the transverse extension direction of the atmosphere light trim, and direction z is defined as the vertical extension direction of the atmosphere light trim.

As shown in fig. 1 and 2, the present invention provides an atmosphere lamp interior part 100 capable of exhibiting different illumination variations according to different usage scenarios, which achieves the effects by the following components:

a light-guiding element 1, the light-guiding element 1 being intended for propagating light rays,

a decorative layer 2, the decorative layer 2 being at least partially sewn to the light-guiding element 1,

a support frame 3, the support frame 3 defining two internal spaces horizontally spaced apart:

a light guide element receiving space 301, the light guide element receiving space 301 being adapted to receive the light guide element 1, the light guide element receiving space 301 being occupied by the light guide element 1 when the light guide element 1 is inserted into the support frame 3, a light source accommodating space 302, the light source accommodating space 302 being adapted to accommodate a light source,

an LED module 4, the LED module 4 being fixedly mounted in the light source headspace 302 to provide a light source,

wherein the light source provided by the LED module 4 propagates horizontally to the light guiding element 1 and vertically through the light guiding element 1 to the outside of the atmosphere light interior 100.

The individual components of the atmosphere lamp trim 100 are described separately below with reference to fig. 3 to 6.

Referring to fig. 3, a light guiding element 1 and a decorative layer 2 at least partially stitched together therewith are shown.

The light guide element 1 serves to transmit a light source from the inner space of the support frame 3 to the outside, thereby exhibiting light variation. In particular, the light guiding element 1 comprises a light guiding body 10 extending in direction z, a first skirt 11 and a second skirt 12 extending from both sides of the light guiding body 10, and a support portion 13 extending in opposite direction with respect to the light guiding body 10.

The light guiding body 10 of the light guiding element 1 is a medium for converting light propagating in the horizontal direction of the LED module into light propagating in the vertical direction into the vehicle compartment. In this atmosphere lamp trim 100, light is emitted only from the light guide body 10, and is not emitted from other portions. In order to improve the light transmission quality, the outer end of the light guide body 10 is rounded.

The first skirt 11 and the second skirt 12 of the light-guiding element 1 are at a distance from the light-guiding body 10, so that the distance between the light-guiding body 10 and the first skirt 11 and the second skirt 12 is approximately equal to the thickness of the decorative layer 2, and thus the decorative layer 2 can be sewn with the first skirt 11 and the second skirt 12 of the light-guiding element 1 better, thereby improving compactness. In other words, the light-guiding body 10 of the light-guiding element 1 and the first and second skirt 11, 12 form a first and second groove 15, 16, respectively, for accommodating the decorative layer 2, and the width of the groove is approximately equal to the thickness of the decorative layer 2 and can be dimensioned according to the decorative layer used.

The first skirt 11 and the second skirt 12 are disposed opposite to each other, and are disposed on two sides of the light guide body 10, and extend along the same direction as the extending direction of the light guide body 10, i.e., the vertical upward direction in fig. 3, and are denoted by a direction z.

Alternatively, the first and second skirts 11 and 12 may be partially hollowed out to save material.

The support portion 13 of the light guide element 1 is used to support the light guide body 10 and the first and second skirts 11 and 12, and the light guide element 1 is inserted into the light guide element accommodating space 301 of the support frame 3 through the support portion 13 thereof, thereby fixing the position of the light guide element 1. The support portion 13 extends in the opposite direction with respect to the light guide body 10 and may be offset from the light guide body 10, which may be configured in a trapezoidal shape in fig. 1 to 3, so as to be inserted into the light guide element receiving space 301 and stably fixed therein.

The light guiding element 1 may be made of thermoplastic polyurethane to form a transparent or translucent shape that can transmit light.

The decorative layer 2 is used to cover the inside of the atmosphere lamp interior 100, to prevent the occupant from seeing the inside of the atmosphere lamp interior 100 from the outside, and to provide the occupant with a comfortable tactile sensation, and for example, the decorative layer 2 may be a material such as genuine leather, artificial leather, fabric, and the like, preferably a material that is opaque to light.

During assembly, the decorative layer 2 is first inserted into the first slot 15 and the second slot 16, and then is at least partially sewn to the first skirt 11 and the second skirt 12, preferably with a sewing thread provided on the side away from the light guide body 10, so that the side of the decorative layer 2 close to the light guide body 10 has no sewing thread, and thus the light transmitted by the light guide body 10 is not affected, and the trace of the sewing thread is not displayed.

The support frame 3 may be fixed to the dashboard, door panel or centre console of the vehicle, thereby providing a stable support for the entire atmosphere light trim. In the present embodiment, a detachable support frame 3 is proposed, which is constituted by a detachable first frame 31 and a second frame 32. The first frame 31 and the second frame 32 have snap bottoms which are integrally formed with each other, and inspection, maintenance and replacement of parts by a maintenance worker are greatly facilitated by such a detachable structure.

Referring to fig. 4, there is shown the first frame 31 supporting the frame 3, the first frame 31 having a first shoulder 131 and a second shoulder 132 for holding the first skirt 11 and the second skirt 12 of the light guide element 1, and the first frame 31 further having a first upper sidewall 161 and a second upper sidewall 162 for holding outer surfaces of the first skirt 11 and the second skirt 12 of the light guide element 1, respectively. The distance from the first upper sidewall 161 to the second upper sidewall 162 is substantially equal to the distance from the outer surface of the first skirt 11 to the outer surface of the second skirt 12 of the light guide element 1, so that the first skirt 11 and the second skirt 12 of the light guide element 1 are not displaced randomly.

The first frame 31 further comprises a first side wall 122 defining a light guiding element receiving space 301 and a first bottom 101, in which first bottom 101 a row of protruding teeth 151 is arranged in the longitudinal direction x of the ambience light trim 100, each protruding tooth 151 having a plurality of partition walls 111 extending therefrom.

The first shoulder 131 of the first frame 31 is supported by the partition walls 111, and the second shoulder 132 of the first frame 31 is supported by the first side wall 122.

When the light guide element 1 is inserted into the light guide element receiving space 301, both sides of the support portion 13 of the light guide element 1 contact the partition wall 111 and the first sidewall 122 of the first frame 31, respectively, and since the support portion 13 of the light guide element 1 is configured in a trapezoidal shape, a wedge effect is generated with the insertion of the support portion 13, thereby improving the stability after installation.

Preferably, when the light guide element 1 is completely inserted into the light guide element accommodating space 301, the light guide element accommodating space 301 is completely occupied by the light guide element 1.

In addition, the first frame 31 can further have an auxiliary support portion 163, the auxiliary support portion 163 extending from the first shoulder portion 131 for assisting in supporting the decoration layer 2 to prevent the decoration layer 2 from collapsing.

Referring then to fig. 5, fig. 5 shows a second frame 32 supporting frame 3, second frame 32 having a second side wall 201 and a second bottom 202 defining a light source headspace 302. The second bottom 202 of the second frame 32 has a complementary row of teeth 203 arranged in the longitudinal direction x of the atmosphere light trim piece 100. Wherein the teeth 151 of the first bottom 101 of the first frame 31 can snap together with the complementary teeth 203 of the second bottom 202 of the second frame 32 to form a complete snap bottom.

The second frame 32 can further comprise a flanging 204 connecting the second side wall 201, the flanging 204 being adapted to contact and provide a supporting force to the auxiliary support 163 of the first frame 31 when the teeth 151 of the first bottom 101 of the first frame 31 and the complementary teeth 203 of the second bottom 202 of the second frame 32 are snapped together to constitute a complete snap bottom.

Preferably, the bottom portions of the first and second frames are made of aluminum or aluminum alloy.

Referring then to fig. 6, fig. 6 shows an LED module 4, which includes a circuit board 41 and an LED strip 42 disposed on the circuit board, where the LED strip 42 may be composed of individual LED tubes, and thus each LED tube may operate independently, so as to achieve the effect of dynamically changing light.

The LED module 4 is fixed on the inner wall 201 of the second frame 32 of the support frame 3. Light emitted therefrom may be injected into the light guide element 1 through the gaps between the partition walls 111 and then be transmitted to the outside through the light guide body 10 of the light guide element 1. As no suture line or joint exists in the path of the light propagation, the light propagated is complete and high in quality.

The manufacturing of the atmosphere lamp trim piece 100 may be achieved by:

in a first step, a light-guiding element 1 and a decorative layer 2 are provided, at least a portion of the decorative layer 2 is inserted into a first groove 15 and a second groove 16 of the light-guiding element 1, and then the decorative layer 2 is at least partially sewn to a first skirt edge 11 and a second skirt edge 12 of the light-guiding element 1,

secondly, the light-guiding element 1 sewn together with the decorative layer 2 is inserted into the first frame 31 of the support frame 3,

and a third step of mounting the LED module into the second sidewall 201 of the second frame 32 of the support frame 3,
