[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figure 6-15 As shown, an ultra-thin, ultra-narrow-border screen structure of a vehicle ceiling screen includes a display screen fixing frame 1, a logic board 2 and an adapter bracket 3 are fixedly arranged on the inner side of the display screen fixing frame 1, the logic board 2 is located between the display screen fixing frame 1 and the adapter bracket 3, and bracket ears 31 extending out of the adapter bracket 3 are provided on both sides of the adapter bracket 3, and the two bracket ears 31 are respectively connected to two flip mechanisms 4, and also includes a display screen module 5 and a decorative cover 6, the decorative cover 6 is fixedly connected to the adapter bracket 3, the display screen module 5 is located between the adapter bracket 3 and the decorative cover 6, the display screen module 5 includes a backlight film material 51, and a positioning groove 11 is provided on the inner side wall of the display screen fixing frame 1, the backlight film material 51 is arranged in the positioning groove 11 and is limited by the positioning groove 11.

[0042] By adopting the above technical solution, in order to compress the overall thickness of the screen, compared with the prior art, the present application cancels the display screen back cover, and at the same time sticks the logic board 2 on the inner wall of the display screen fixing frame 1 through the adhesive 55, and additionally provides an adapter bracket 3. The purpose of the adapter bracket 3 is to support the display screen module 5. The adapter bracket 3 is locked to the display screen fixing frame 1 by screw fastening, and finally the display screen module 5 and the decorative cover 6 are assembled; and in order to further reduce the overall thickness of the screen, bracket ears 31 extending out of the adapter bracket 3 are provided on both sides of the adapter bracket 3, and two flip mechanisms 4 are locked on the bracket ears 31 by screw fastening. The bracket ears 31 and the flip mechanism 4 adopt a split structure, which can realize the screen being removable later and easy to repair and replace; and in order to compress the size of the screen frame, compared with the prior art, the present application cancels the middle iron frame, and by providing a positioning groove 11 on the inner side wall of the display screen fixing frame 1, the backlight film material 51 is limited in the height direction and the expansion of the backlight film material 51 is avoided. In this way, the technical solution can realize an ultra-thin, ultra-narrow-border screen structure, eliminate the display screen back cover, directly fix the logic board 2 on the inner side of the display screen fixing frame 1, and set the adapter bracket 3 structure, which greatly reduces the overall thickness of the screen. By setting the positioning groove 11 and eliminating the middle iron frame, the screen frame size is made smaller, achieving the purpose of a narrower border. The innovative setting of the adapter bracket 3 is used to support the display screen module 5 and can also achieve connection with the flip mechanism 4.

[0044] Among them, avoidance grooves 14 corresponding to the bracket ears 31 are provided on the two sides of the accommodating groove 12 on the inner side of the display screen fixing frame 1. The setting of the avoidance grooves 14 allows the bracket ears 31 to extend, preventing the bracket ears 31 from being located in the display screen fixing frame 1 and increasing the overall thickness of the screen.

[0045] The logic board 2 is glued and fixed to the display screen fixing frame 1, and the adapter bracket 3 is fixed to the display screen fixing frame 1 through fasteners. The logic board 2 is fixed to the display screen fixing frame 1 by gluing with adhesive 55, and the adapter bracket 3 is connected to the display screen fixing frame 1 through fasteners, so as to better ensure the stable connection between the logic board 2 and the adapter bracket 3.

[0046] Moreover, one of the two flipping mechanisms 4 is an active flipping mechanism 4 and the other is a driven flipping mechanism 4. By setting one side as an active flipping mechanism 4 and the other side as a driven flipping mechanism 4, the production cost can be effectively reduced, and the structure is simple and the transmission is stable.

[0047] In addition, the adapter bracket 3 is provided with a first step groove 32, a second step groove 33 and a third step groove 34 arranged in sequence from low to high in the height direction. The arrangement of the first step groove 32, the second step groove 33 and the third step groove 34 can be used to accommodate and position other components included in the display screen module 5, such as the FOG screen 54 or the cover plate 52.

[0048] A limiting groove 35 is provided on the adapter bracket 3, and a limiting insert ring 61 adapted to the limiting groove 35 is provided on the decorative cover 6. With such a configuration, the decorative cover 6 can be well positioned through the cooperation between the limiting groove 35 and the limiting insert, and can be stably connected to the adapter bracket 3 through fasteners.

[0049] Among them, the display screen module 5 also includes a cover plate 52, OCA optical glue 53, FOG screen 54, back glue 55, foam 56 and a light board 57. The light board 57 is arranged between the backlight film material 51 and the display screen fixing frame 1, the back glue 55 is pasted between the display screen fixing frame 1 and the cover plate 52, the FOG screen 54 is arranged between the cover plate 52 and the backlight film material 51, the OCA optical glue 53 is pasted between the cover plate 52 and the FOG screen 54, and the foam 56 is arranged at the connection between the FOG screen 54 and the display screen fixing frame 1 and / or the adapter bracket 3. In this way, a complete display screen module 5 can be formed. The overall screen structure is compact, the thickness is greatly reduced compared with the existing technology, and it has a narrow frame, which improves the user's visual experience of watching the screen.
