Description

Technical Field

[0001] This application relates to the technical field of vehicle-mounted products, and in particular to a process and structure for a starry sky roof display screen for vehicle roof mounting. Background Technology

[0002] In recent years, the requirements for car roofs have changed significantly. The market has increasingly higher demands for improving the interior ambiance, and the introduction of illuminated roofs has taken an important step in enhancing this ambiance. Among illuminated roofs, the starry sky roof is particularly popular.

[0003] Current automotive starry sky ceiling effects are typically achieved using starry sky display screens, which are glued to the car's ceiling. The installation process requires manually applying adhesive before attaching the screen to the ceiling. However, this method is prone to air bubbles, and the edges of the screen need to be tucked into the roof edge, which can damage the screen and affect the display quality. Furthermore, the installation is time-consuming, typically requiring 2-4 hours. This issue urgently needs to be addressed. Summary of the Invention

[0004] In order to improve the display effect of the starry sky roof display and reduce the installation time, this application provides a process and structure for a starry sky roof display for vehicle roof installation.

[0005] This application provides a process and structure for a starry sky roof display screen for vehicle roof mounting, which adopts the following technical solution: A process for installing a starry sky roof display screen on a vehicle roof includes the following steps: S1: The starry sky roof display screen is bonded to the tempered glass that is compatible with the car roof using optical adhesive to form a semi-finished component; S2: Remove air bubbles generated when the starry sky ceiling display screen is bonded and fixed to the tempered glass with optical adhesive; S3: Install the semi-finished components after removing air bubbles onto the roof of the vehicle. The tempered glass in the semi-finished components is fixed to the roof via a detachable connection.

[0006] By adopting the above technical solution, during the installation of the starry sky roof display, the display is first bonded to the tempered glass of the vehicle roof using optical adhesive, forming a semi-finished component. Then, air bubbles generated during the optical adhesive bonding process are removed, which improves the display effect. Finally, the tempered glass in the semi-finished component is fixed to the vehicle roof using a detachable connection. The entire installation process does not damage the starry sky roof display, and the step of removing air bubbles is addressed before installation. The detachable connection method for fixing the tempered glass to the roof is convenient and quick, thus reducing installation time.

[0007] Preferably, in step S1, the surfaces of the starry sky display screen and the tempered glass are cleaned and dried before electrostatic removal is performed.

[0008] By adopting the above technical solutions, the cleaning, drying, and electrostatic treatment of the starry sky ceiling display screen and tempered glass can improve cleanliness, thereby improving the display effect of the starry sky ceiling display screen after installation.

[0009] Preferably, in step S2, the semi-finished components are sent into a central vacuum machine for the first defoaming operation.

[0010] By adopting the above technical solution, the semi-finished components are sent into the central vacuum machine for the first defoaming operation, which can transfer the air bubbles in the middle between the starry sky top display screen and the tempered glass to the outside, thereby eliminating the air bubbles.

[0011] Preferably, after the first defoaming operation is completed, the semi-finished component after the first defoaming operation is wrapped in a micro airbag and then placed in a central vacuum machine for a second defoaming operation.

[0012] By adopting the above technical solution, after the first bubble removal operation, the bubbles in the middle between the starry sky top display and the tempered glass move outward to the edge. At this time, the bubble removal is not thorough, and the bubbles at the edge will still affect the display effect. By using micro airbags to wrap the semi-finished components and performing a second bubble removal operation, the bubbles at the edge between the starry sky top display and the tempered glass continue to move outward, thereby making the bubbles disappear from between the starry sky top display and the tempered glass, achieving the effect of completely eliminating bubbles, which is conducive to further improving the display effect of the starry sky top display.

[0013] Preferably, the micro airbag comprises a PVC film and a PET film. The PVC film is coated with optical adhesive, dried, and bonded to the starry sky top display screen. The PET film is coated with optical adhesive, dried, and bonded to the tempered glass. The edges of the bonded PVC film and PET film are overlapped and connected to form a micro airbag.

[0014] By adopting the above technical solution, the PVC film is coated with optical adhesive, dried, and bonded to the starry sky top display screen. The PET film is coated with optical adhesive, dried, and bonded to the tempered glass. The edges of the bonded PVC film and PET film are overlapped and connected to form a micro airbag and wrap the semi-finished component. When the second debubbling operation is performed, the air bubbles located at the edge between the starry sky top display screen and the tempered glass can continue to move outward, thereby completely removing the air bubbles from between the starry sky top display screen and the tempered glass.

[0015] Preferably, after the micro-airbag-wrapped semi-finished component undergoes a second defoaming operation, the PVC film and PET film are removed.

[0016] By adopting the above technical solution, after the second defoaming operation is completed, there are no more air bubbles between the starry sky roof display and the tempered glass. At this time, the PVC film and PET film can be removed to facilitate the subsequent installation of the semi-finished components on the roof.

[0017] Preferably, during both the first and second defoaming operations, the pressure range for defoaming by the central vacuum machine is set to 10-12 kg / cm². 2 The defoaming time is set to 40-50 minutes, and the temperature range is set to 45-55℃.

[0018] By adopting the above technical solution, the pressure range during the defoaming process in the central vacuum machine is set to 10-12 kg / cm². 2 The defoaming time is set to 40-50 minutes, and the temperature range is set to 45-55℃. Setting the parameters within these ranges can effectively remove bubbles.

[0019] Preferably, the drying temperature range for PVC film and PET film after coating with optical adhesive is set to 22-25℃, and the drying time range is set to 50-70min.

[0020] By adopting the above technical solution, the range of drying temperature and drying time can be set to improve the drying effect, thereby improving the bonding effect.

[0021] A roof-mounted starry sky display structure, employing the aforementioned roof-mounted starry sky display process, includes a first starry sky display, optical adhesive, and tempered glass. The first starry sky display is bonded and fixed to the tempered glass surface facing away from the roof using the optical adhesive.

[0022] By adopting the above technical solution, the first starry sky roof display screen is fixed to the tempered glass surface away from the car roof by optical adhesive. This transforms the subsequent installation of the first starry sky roof display screen on the car roof into the installation of the tempered glass on the car roof. The installation process will not damage the first starry sky roof display screen, and the air bubble removal operation is performed beforehand, without needing to be done inside the car, which helps to improve the convenience of installation.

[0023] Preferably, it also includes a second starry sky roof display screen, which is fixed to the tempered glass surface facing the vehicle roof by the optical adhesive.

[0024] By adopting the above technical solution, the second starry sky roof display is fixed to the tempered glass surface facing the roof of the vehicle by optical adhesive. The second starry sky roof display can perform display effects such as dimming, frosting or transparency, which helps to improve the diversity of atmosphere.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By bonding the starry sky roof display to the tempered glass of the vehicle roof using optical adhesive, a semi-finished component is formed. After removing air bubbles between the starry sky roof display and the tempered glass, the air-bubble-free semi-finished component is installed on the vehicle roof. The tempered glass in the semi-finished component is fixed to the vehicle roof using a detachable connection method. The entire installation process will not damage the starry sky roof display, and the step of removing air bubbles before installation helps to improve the display effect. The operation of fixing the tempered glass to the vehicle roof using a detachable connection method is convenient and quick, thereby reducing installation time.

[0026] 2. By sending the semi-finished components into the central vacuum machine for the first defoaming operation, the air bubbles in the middle between the starry sky display screen and the tempered glass can be transferred outward, thereby eliminating the air bubbles.

[0027] 3. After the first debubbling operation, the air bubbles in the middle between the starry sky display screen and the tempered glass move outward to the edge. At this point, the debubbling is not complete, and the air bubbles at the edge will still affect the display effect. After the first debubbling operation, the semi-finished components after the first debubbling operation are wrapped with micro airbags and placed in the central vacuum machine for a second debubbling operation. This allows the air bubbles at the edge between the starry sky display screen and the tempered glass to continue to move outward, thereby making the air bubbles disappear from between the starry sky display screen and the tempered glass. This achieves the effect of completely eliminating air bubbles and helps to further improve the display effect of the starry sky display screen. Attached Figure Description

[0031] Explanation of reference numerals in the attached figures: 1. First starry sky ceiling display screen; 2. Optical adhesive; 3. Tempered glass; 4. Second starry sky ceiling display screen. Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail. Example

[0033] Embodiment 1 of this application discloses a process for installing a starry sky roof display screen on a vehicle roof, referring to... Figure 1 This includes the following steps: S1: The starry sky roof display screen is bonded to the tempered glass that is compatible with the car roof using optical adhesive to form a semi-finished component; S2: Remove air bubbles generated when the starry sky ceiling display screen is bonded and fixed to the tempered glass with optical adhesive; S3: Install the semi-finished components after removing air bubbles onto the roof of the vehicle. The tempered glass in the semi-finished components is fixed to the roof via a detachable connection.

[0034] During the installation of the starry sky roof display, the display is first bonded to the tempered glass of the vehicle roof using optical adhesive, forming a semi-finished assembly. Air bubbles generated during the adhesive bonding process are then removed to improve the display effect. Finally, the tempered glass is detachably fixed to the roof. The entire installation process does not damage the starry sky display, and the air bubble removal process is pre-emptive. The detachable connection method for fixing the tempered glass to the roof is convenient and quick, reducing installation time. In this embodiment, a snap-fit ​​structure is used for the detachable connection of the tempered glass to the roof. This snap-fit ​​structure is a standard feature of detachable connection structures and will not be elaborated upon here. In other embodiments, a hanging method can also be used, which is not limited here.

[0035] In step S1, the surfaces of the starry sky roof display and the tempered glass are cleaned and dried, and then electrostatic removal is performed to improve cleanliness, which is beneficial to improving the display effect of the starry sky roof display after installation.

[0036] In step 2, the semi-finished component is sent to a central vacuum chamber for the first debubbling operation, which moves the air bubbles in the middle between the starry sky display screen and the tempered glass outward, thus eliminating the bubbles. However, after the first debubbling operation, the air bubbles in the middle between the starry sky display screen and the tempered glass move outward to the edges. At this point, the debubbling is not thorough, and the air bubbles at the edges still affect the display effect. To solve this problem, after the first debubbling operation, a micro-airbag is used to wrap the semi-finished component after the first debubbling operation, and it is placed in the central vacuum chamber again for a second debubbling operation. This allows the air bubbles at the edges between the starry sky display screen and the tempered glass to continue to move outward, thus eliminating the air bubbles completely between the starry sky display screen and the tempered glass, which helps to further improve the display effect of the starry sky display screen.

[0037] Specifically, the miniature airbag comprises a PVC film and a PET film. The PVC film is coated with optical adhesive, dried, and bonded to the starry sky roof display. The PET film is coated with optical adhesive, dried, and bonded to the tempered glass. The edges of the bonded PVC and PET films overlap and connect to form a miniature airbag that encloses the semi-finished component. During the second debubbling operation, air bubbles located at the edge between the starry sky roof display and the tempered glass can continue to move outward, thus completely removing the air bubbles from between the starry sky roof display and the tempered glass. After the miniature airbag encloses the semi-finished component and undergoes the second debubbling operation, the PVC and PET films are removed, allowing the semi-finished component to be installed on the vehicle roof.

[0038] It should be noted that during both the first and second defoaming operations, the pressure range for defoaming by the central vacuum machine was set to 10-12 kg / cm². 2 The defoaming time is set to 40-50 minutes, and the temperature range is set to 45-55℃. In this embodiment, the defoaming pressure of the central vacuum machine is set to 12 kg / cm². 2 The defoaming time was set to 45 minutes and the temperature to 50℃ to achieve a better defoaming effect.

[0039] In addition, the drying temperature range for PVC film and PET film after coating with optical adhesive is set to 22-25℃, and the drying time range is set to 50-70 minutes. In this embodiment, the drying temperature is set to 23℃ and the drying time is set to 60 minutes to improve the drying effect, thereby improving the adhesion effect.

[0040] The implementation principle of the starry sky roof display screen for vehicle roof installation in Embodiment 1 of this application is as follows: During the installation of the starry sky roof display screen, it is first fixed to the tempered glass adapted to the vehicle roof using optical adhesive. The starry sky roof display screen and the tempered glass form a semi-finished component. Then, the air bubbles generated by the optical adhesive fixing between the starry sky roof display screen and the tempered glass are removed. The air bubble removal process includes a first air bubble removal operation and a second air bubble removal operation. The first air bubble removal operation moves the air bubbles in the middle between the starry sky roof display screen and the tempered glass outward to the edge position. The second air bubble removal operation continues to move the air bubbles at the edge position between the starry sky roof display screen and the tempered glass outward, so that the air bubbles disappear from between the starry sky roof display screen and the tempered glass, achieving the effect of completely eliminating air bubbles, thereby improving the display effect. Finally, the tempered glass in the semi-finished component is fixed to the vehicle roof using a detachable connection method with clips. The entire installation process will not damage the starry sky roof display screen, and the step of generating air bubbles is dealt with in advance before installation. The operation of fixing the tempered glass to the vehicle roof is convenient and quick, thereby reducing installation time. Example

[0041] Embodiment 2 of this application discloses a structure for a starry sky roof display screen for vehicle roof mounting, referring to... Figure 2 The system includes a first starry sky roof display 1, optical adhesive 2, and tempered glass 3. The first starry sky roof display 1 is bonded and fixed to the surface of the tempered glass 3 facing away from the roof using optical adhesive 2. This transforms the subsequent installation of the first starry sky roof display 1 into the installation of the tempered glass 3 on the roof. The installation process will not damage the first starry sky roof display 1, and the air bubble removal operation is performed beforehand, eliminating the need to be done inside the vehicle, which improves the convenience of installation. Example

[0042] Embodiment 3 of this application discloses a structure for a starry sky roof display screen for vehicle roof mounting, referring to... Figure 3 The difference from Embodiment 2 of this application is that it also includes a second starry sky roof display screen 4. The second starry sky roof display screen 4 is bonded and fixed to the surface of the tempered glass 3 facing the roof by optical adhesive 2. The second starry sky roof display screen 4 can perform display effects such as dimming, frosting or transparency, thereby helping to improve the diversity of atmosphere.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
