[0018] The structure of the present utility model will be further described below with reference to the drawings.

[0019] Refer to Figures 1 to 3 , the in-vehicle display screen of the present utility model includes a glue frame 1, a backlight module 2, a display module 3, a display screen body 4 and a back frame 5. A display module installation groove 11 is provided on the glue frame 1, the display module 3 is located in the display module installation groove 11, a backlight module installation groove 51 is provided at the bottom of the back frame 5, the backlight module is placed in the backlight module installation groove, a glue frame mounting table 52 is provided on the inner side wall of the back frame above the backlight module installation groove, the glue frame is placed in the glue frame mounting table, trapezoidal protrusions 53 are provided at the four corners of the top of the back frame 5, the display screen body is located on the trapezoidal protrusions, and the display screen body and the top surface of the back frame are bonded by hot melt adhesive. When the display screen body and the back frame are installed, the display screen body is located on the trapezoidal protrusions, the display screen body and the top surface of the back frame are bonded by hot melt adhesive. After bonding, when the display screen body and the glue frame mounting table are pressed tightly, a hot melt adhesive with a predetermined thickness is formed between the display screen body and the top surface of the glue frame. Even if the display screen body and the top surface of the glue frame are uneven, there is hot melt adhesive filling and the display screen body and the top surface of the glue frame will not crack, thereby preventing light leakage. At the same time, anti-overflow glue will not cause scratches to the ink on the cover glass.

[0020] In this embodiment, the edge cross-section of the glue frame 1 is L-shaped. There are overflow glue bosses 12 protruding outward on the outer sides of the four sides of the glue frame. A U-shaped overflow glue area 6 is formed between the overflow glue bosses and the inner side of the backlight. A circle of overflow glue area is formed between the overflow glue bosses and the inner side of the backlight. When the display screen body is pressed against the trapezoidal protrusion, even if there is overflow glue, the overflow glue enters the U-shaped overflow glue area, and the glue will not overflow onto the internal backlight module and display module.

[0021] In this embodiment, an outwardly bent extension edge 13 is provided on the outer side of the top of the glue frame 1. A corresponding extension edge positioning groove 54 for cooperating with the extension edge is provided on the back frame 5, and the extension edge is placed in the extension edge positioning groove. In this embodiment, the extension edge is trapezoidal. Specifically in implementation, the extension edge can also be rectangular, arc-shaped or other special-shaped ones. The extension edge is placed in the extension edge positioning groove, thereby positioning between the glue frame and the back frame.

[0022] In this embodiment, the back frame is a die-cast part. There is a trapezoidal protrusion on both sides of each of the four corners at the top of the back frame. Thus, the positioning between the back frame and the display screen body is stable. The trapezoidal protrusion has the same width as the material thickness of the back frame, which is convenient for manufacturing and at the same time makes the positioning between the back frame and the display screen body stable. The four corners of the trapezoidal protrusion are provided with arc-shaped chamfers. It is convenient for the hot melt glue to fill each gap between the back frame and the display screen body. The top length of the trapezoidal protrusion is 1 mm. Such a size of the trapezoidal protrusion results in less overflow glue, and at the same time prevents light leakage and no ink pressing damage.

[0023] Although the specific implementation manners of the present invention have been described in detail in conjunction with the accompanying drawings, it should not be construed as a limitation to the protection scope of the present invention. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative labor still fall within the protection scope of the present invention.
