[0017] A fixing component 2 is provided on each of the two first sides of the light guide component 3; the first end 211 of the fixing component 2 is connected to the roof of the vehicle; the second end 223 of the fixing component 2 is connected to the light guide component 3, and an accommodating cavity 5 is formed between the second end 223 and the first end 211 of the fixing component 2. The light source 4 is provided in the accommodating cavity 5, and the output light of the light source 4 enters the light guide component 3 from the side of the light guide component 3.

[0018] In this embodiment, a fixing component 2 is respectively provided on two first sides of the light guide component 3. It should be explained in detail that a fixing component 2 is respectively provided on two sides of the light guide component 3 in the X direction.

[0019] The first end 211 of the fixing component 2 is connected to the roof of the vehicle. It should be noted that the first end 211 of the fixing component 2 is a glue overflow groove, the purpose of which is to allow excess glue to overflow to ensure that the glue in the cavity is neither too much nor too little.

[0020] The light source 4 needs to be explained in detail. The light source 4 can be an LED light sheet, and is equipped with a dimmer to achieve cold, warm, bright and dark dimming.

[0021] The fixing assembly 2 of this embodiment can not only be fixed to the roof, but also fix the light guide assembly 3 and accommodate the light source 4, with high integration. The light source 4 is arranged in the accommodating cavity 5 of the fixing assembly 2, without occupying the top space of the bus.

[0022] 3 and 4 , a starry sky ceiling further includes a fixing bracket 7 , and a fixing bracket 7 is respectively provided on the two second sides of the light guide assembly 3 .

[0023] In this embodiment, a fixing bracket 7 is respectively provided on the two second sides of the light guide component 3 . It should be explained in detail that a fixing bracket 7 is respectively provided on the two sides of the light guide component 3 in the Y direction.

[0024] The fixing bracket 7 of this embodiment is arc-shaped, and one side of the light guide assembly 3 along the width direction is bonded to the arc-shaped bracket to give it an arc-shaped top effect, thereby preventing the light guide assembly 3 from collapsing downward due to its own gravity.

[0025] 3 and 4 , in this embodiment, the light guide assembly 3 includes a pattern plate 33 , a light guide plate 32 and a reflective plate 31 .

[0026] The light guide plate 32 is disposed on the pattern plate 33 ; the reflector 31 is disposed on the light guide plate 32 ; one of the pattern plate 33 and the light guide plate 32 can be bent to remove the black shadow at the top edge of the starry sky.

[0027] 3 , the light guide plate 32 is bendable. In this embodiment, the light guide plate 32 may be made of acrylic material. Therefore, both edges of the light guide plate 32 are vertically bent by heat and then connected to the roof.

[0028] After the edges of the joints of the two light guide plates 32 are vertically hot-bent, the bent parts are bonded and fixed to the arc-shaped fixing bracket 7, which not only solves the problem of fixing the starry sky roof to the roof, but also removes the shadows, ensuring the stability of the product and the overall aesthetics.

[0029] Referring to FIG. 4 , the pattern plate 33 is bent. In this embodiment, the edge of the pattern plate 33 is vertically bent by heat bending. The light guide plate 32 and the reflector 31 are aligned to support the pattern plate 33 and are bonded to the side of the pattern plate 33. The upper half of the light guide plate 32 after heat bending is bonded to the curved aluminum alloy fixing bracket 7 to keep the light guide plate 32 curved.

[0030] The edges of the pattern plate 33 are vertically hot-bent, and the light guide plate 32 and the pattern plate 33 are connected by side gluing, which avoids the white tape showing on the front; the light guide plate 32 is 3-5mm thick, has high strength, is not easy to deform, and can achieve sufficient lifting for the starry sky ceiling.

[0031] The pattern plate 33 on the outermost layer of the light guide assembly 3 of this embodiment can achieve different pattern effects through different manufacturing processes.

[0032] 3 and 4 , the fixing bracket 7 is bent toward the vehicle roof to limit the deformation of one of the pattern plate and the light guide plate due to gravity.

[0033] 3 , one end 71 of the fixing bracket 7 is connected to the vehicle roof, and the other end 72 is connected to the bent end 321 of the light guide plate 32 , so that the light guide assembly 3 maintains an arc shape.

[0034] 4 , the fixing bracket 7 is connected to the bent end 331 of the pattern plate 33 , so that the light guide assembly 3 maintains an arc shape.

[0035] 2 , the fixing assembly includes a first connecting member 21 , a first end 211 of the first connecting member 21 being connected to the vehicle roof; a second connecting member 22 , a receiving cavity 5 being formed between the first end 221 and the second end 224 of the second connecting member 22 , and a second end 224 of the second connecting member 22 being connected to the light guide assembly 3 ;

[0036] The third connecting member 23 and the first end 221 of the second connecting member 22 are connected to the third connecting member 23 and the second end 212 of the first connecting member 21 respectively.

[0037] In this embodiment, the first end 211 of the first connecting member 21 is connected to the vehicle roof, and it should be explained in detail that the connection is made by adhesive.

[0038] The first end 221 of the second connecting member 22 is connected to the third connecting member 23 and the second end 212 of the first connecting member 21 respectively. It should be noted that the first end 221 of the second connecting member 22 is connected to the third connecting member 23 via a screw 25 .

[0039] The first end 221 of the second connecting member 22 is connected to the second end 212 of the first connecting member 21 via a rivet 26 .

[0040] In this embodiment, the first connecting member 21, the second connecting member 22, and the third connecting member 23 are made of aluminum alloy. When maintenance is required, the screws 25 are first removed, and then the third connecting member 23 is removed. This does not affect the fixed relationship between the first connecting member 21, the second connecting member 22, and the light guide assembly 3. Next, the light guide assembly 3 and the light source 4 are removed in sequence, and then the rivets 26 are removed. Finally, the second connecting member 22 is removed. This structural design facilitates maintenance and repair of the interior of the starry sky roof, and has the advantages of simple assembly and disassembly and an overall beautiful appearance.

[0041] 1 , the third connecting member 23 includes a mounting portion 233 and a supporting portion 232 ; the mounting portion 233 is connected to the first end 221 of the second connecting member 22 , and the supporting portion 232 is used to support the third end 222 of the second connecting member 22 .

[0042] In this embodiment, the supporting portion 232 of the third connecting member 23 is used to further enhance the supporting strength of the third end 222 of the second connecting member 22 , thereby making the light guide assembly 3 more firmly fixed.

[0043] 1 , the mounting portion 233 is a groove 234 , the top of the groove 234 is connected to the first end 221 of the second connector 22 , and a decorative plate 6 is disposed at the bottom opening of the groove 234 .

[0044] In this embodiment, the decorative panel 6 makes the interior space of the vehicle more beautiful.

[0045] 2 , a limiting portion 8 is provided between the mounting portion of the third connecting member 23 and the supporting portion.

[0046] The limiting portion 8 in this embodiment abuts against the light source 4 to prevent the light source 4 from shaking.

[0047] 2 , a protrusion 226 is provided on an end surface of the second end 224 of the second connecting member 22 .

[0048] In this embodiment, there are two protrusions 226 , but there may also be multiple protrusions 226 .
