A pad 12 is provided on the edge of the main speaker slot 11 furthest from the vehicle body to increase the depth of the main speaker slot 11. A main speaker cover 13 covers the main speaker slot 11, and the rear-end speakers are placed inside the main speaker cover 13. The main speaker cover 13 is connected to the pad 12 to protect the speakers inside the main speaker slot 11.

[0022] In use, firstly, the main bracket 1, secondary bracket 2, and curved plate 4 are assembled into a single frame. Then, the roof liner 5 is fixed to the top of this frame. Subsequently, the frame with the roof liner 5 installed is bolted to the side wall inside the car, ensuring that the roof liner 5 fits snugly against the car's roof. The roof liner 5 has several holes. By threading several optical fibers through these holes, one end of each fiber connects to an LED light source hidden at the edge of the roof, while the other end shines through the holes, forming a "star" effect. The light emitted by the light source is efficiently conducted to the roof surface through the principle of total internal reflection of the optical fiber, and then scattered by the material. This creates a soft, uniform starlight effect, giving the roof lining 5 a starry sky atmosphere. During the installation of the frame consisting of the main bracket 1, the secondary bracket 2, and the arc plate 4 into the car, the main speaker slot 11 is aligned with the rear speaker of the car. When the frame is fixed to the car, the rear speaker is positioned within the main speaker slot 11. The pad 12 provides sufficient space for the main speaker slot 11, allowing the rear speaker to be fully placed within it and enclosed by the main speaker cover 13.

[0023] Furthermore, the pad 12 is fixedly installed on the main bracket 1, the main horn cover 13 is fixedly connected to the pad 12, and the main horn cover 13 has several small holes evenly distributed on the main horn cover 13. The main bracket 1 has a locking block 14 fixedly connected to both ends.

[0024] The small holes on the main speaker cover 13 can effectively isolate dust, preventing dust inside the car from entering the main speaker slot 11 through the main speaker cover 13 and adhering to the car audio system, thus affecting the normal operation of the car audio system. At the same time, the small holes on the main speaker cover 13 can also effectively conduct the sound played by the car audio system, avoiding the installation of the main speaker cover 13 from reducing the sound quality of the car audio system.

[0025] Furthermore, slots 21 are provided on both ends of the sub-support 2. The slot 21 on the end of the sub-support 2 closest to the main support 1 corresponds to the locking block 14 on the main support 1. The locking block 14 is connected to the slot 21 on the end of the sub-support 2 closest to the main support 1 by a locking mechanism.

[0026] The engagement of the locking block 14 with the locking slot 21 enables the sub-support 2 and the main support 1 to be quickly assembled and disassembled.

[0027] Furthermore, the sub-support 2 has a mounting groove 22 in the middle, and a number of locking grooves 23 are provided on the inner wall of the mounting groove 22.

The two air conditioner mounting ports 24 are located on both sides of the mounting groove 22. A number of fixing blocks 241 are fixedly installed on the inner wall of the air conditioner mounting port 24. The number of fixing blocks 241 are evenly and orderly arranged around the inner wall of the air conditioner mounting port 24.

[0028] When the frame assembled from the main bracket 1, the secondary bracket 2, and the arc plate 4 is installed on the car, the air conditioner inside the car can be installed on the air conditioner installation port 24. Through the setting of the fixing block 241, the bolts used to fix the car air conditioner can be inserted into the fixing block 241, thereby fixing the car air conditioner on the air conditioner installation port 24.

[0029] Furthermore, a side lamp cover 3 is installed in the mounting groove 22. Several locking blocks 31 are fixedly connected to the side of the side lamp cover 3 facing the locking groove 23. Each locking block 31 corresponds to a locking groove 23. The locking blocks 31 are fixed in the locking groove 23 by snap-fit, so that the side lamp cover 3 is fixed in the mounting groove 22.

[0030] The side lamp cover 3 is equipped with an LED light that is connected to a power source. When the starry sky atmosphere effect on the roof lining 5 is turned on, the LED light inside the side lamp cover 3 will light up at the same time, further enhancing the atmosphere effect inside the car.

[0031] Furthermore, a connecting block 41 is fixedly connected to the side of the arc plate 4 near the sub-support 2. The connecting block 41 corresponds to the slot 21 on the side of the sub-support 2 near the arc plate 4. The connecting block 41 is fixed in the slot 21 by snap-fit, so that the arc plate 4 is fixedly connected to the main support 1. A secondary speaker slot 42 is provided on the arc plate 4. The secondary speaker slot 42 is used to place the car side speaker. A secondary speaker cover 43 is provided on the secondary speaker cover 43. The car side speaker is placed inside the secondary speaker cover 43. Several small holes are evenly provided on the secondary speaker cover 43.

[0032] When the frame assembled from the main bracket 1, the secondary bracket 2, and the arc plate 4 is installed on the car, the secondary speaker slot 42 corresponds to the car's side speaker, allowing the car's side speaker to be placed inside the secondary speaker slot 42 and covered by the secondary speaker cover 43. The several small holes on the secondary speaker slot 42 not only isolate dust but also effectively transmit the sound played by the car's side speaker, enabling the car's rear speaker to work in conjunction with the car's side speaker to play a stereo sound effect inside the car.

[0033] Furthermore, a lamp holder 51 is fixedly installed at the bottom of the roof liner 5. The lamp holder 51 is located in the center of the roof liner 5. A slot 511 is opened on the lamp holder 51. An ambient light 52 is fixedly connected to the lamp holder 51. A control button 521 is fixedly installed at the bottom of the ambient light 52. The control button 521 is used to control the opening and closing of the ambient light 52. A transmission interface 522 is also fixedly connected to the ambient light 52. The transmission interface 522 is located inside the slot 511.

[0034] The ambient light 52 further enhances the atmospheric effect presented by the roof lining 5, making the car interior more beautiful. Passengers can directly turn the ambient light 52 on or off using the control button 521, providing convenience and improving the passenger experience.

[0035] Furthermore, the transmission interface 522 is connected to the vehicle's control terminal via an electrical signal, and the transmission interface 522 can also send electrical signals to the ambient light 52 to control the opening and closing of the ambient light 52.

[0036] When it is necessary to remotely control the ambient light 52 to turn it on or off, the vehicle's control terminal can send an electrical signal to the transmission interface 522 to turn the ambient light 52 on or off. The transmission interface 522 transmits these electrical signals to the ambient light 52. The ambient light 52 lights up after receiving the electrical signal to turn on, and turns off after receiving the electrical signal to turn off.

[0037] Furthermore, the frame composed of the main bracket 1, the secondary bracket 2, and the arc plate 4 is tilted inward in a frustum shape, which can be fitted into the inner wall of the car's top.

[0038] The present invention also provides an installation method using the aforementioned automotive interior starry sky roof.

[0039] Working principle: In use, firstly, the main bracket 1, secondary bracket 2, and arc plate 4 are assembled into a whole frame. Then, the roof liner 5 is fixed to the top of this frame. Subsequently, the frame with the roof liner 5 installed is fixed to the side wall inside the car with bolts, so that the roof liner 5 fits snugly against the car roof. The roof liner 5 has several holes. By threading several optical fibers one by one into these holes, one end of the optical fiber is connected to an LED light source hidden at the edge of the roof, while the other end shines out from the hole, forming a "star". The light emitted by the light source passes through the total reflection of the optical fiber. The light is efficiently transmitted to the roof surface and then scattered by the material, forming soft and uniform starlight, thus creating a starry sky atmosphere effect on the roof lining 5. During the installation of the frame consisting of the main bracket 1, secondary bracket 2, and curved plate 4 into the car, the main speaker slot 11 is aligned with the rear speaker of the car. When the frame is fixed to the car, the rear speaker is positioned precisely within the main speaker slot 11. The pad 12 provides sufficient space for the main speaker slot 11, allowing the rear speaker to be fully placed within the main speaker slot 11 and enclosed within the main speaker cover 13. Meanwhile, the secondary... The speaker slot 42 corresponds to the side speaker of the car, allowing the side speaker to be placed inside the secondary speaker slot 42 and covered by the secondary speaker cover 43. Several small holes on the main speaker cover 13 and the secondary speaker slot 42 effectively isolate dust, preventing dust from the car's interior from adhering to the car's audio system and affecting its normal operation. Simultaneously, the small holes on the main speaker cover 13 and the secondary speaker cover 43 effectively conduct the sound played by the car's audio system, preventing the installation of the main speaker cover 13 and the secondary speaker cover 43 from reducing the sound quality of the car's audio system. When this frame is installed, the car's air conditioning... Installed onto the air conditioning mounting port 24, the fixing block 241 allows the bolts used to fix the car air conditioner to be inserted into the fixing block 241, thereby fixing the car air conditioner onto the air conditioning mounting port 24. When passengers are in the car, they can directly turn the ambient light 52 on or off via the control button 521, or send an electrical signal to the transmission interface 522 to turn the ambient light 52 on or off via the car's control terminal. The transmission interface 522 transmits these electrical signals to the ambient light 52. The ambient light 52 lights up after receiving the on electrical signal and turns off after receiving the off electrical signal.
