By increasing the use of inexpensive LEDs, the same brightness effect can be achieved, reducing material costs.

Description

Technical Field

[0001] This utility model belongs to the field of vehicle display technology, specifically, it relates to a vehicle display structure. Background Technology

[0002] In recent years, the domestic automobile industry has developed rapidly, and the competition among major OEMs has been fierce. As a human-machine interaction window, the in-vehicle display screen has an increasingly rich application scenario. The cost and reliability of the display screen have a certain impact on the pricing of the whole vehicle and even the terminal sales.

[0003] A patent specification published on October 25, 2024, with patent number 202420262550.X, discloses a vehicle-mounted display screen structure with anti-static edge-sealing tape. The structure includes a glass cover, optical film, a display screen, a backlight assembly, anti-static edge-sealing tape, shock-absorbing foam, a backlight plastic frame, a light guide plate, an aluminum alloy back cover, conductive tape, copper foil, and a black film. The backlight assembly includes shock-absorbing foam, a backlight plastic frame, a light guide plate, and an aluminum alloy back cover. This anti-static edge-sealing tape structure solves problems such as screen flickering and distorted images encountered by end-users when touching the display screen, improving product lifespan and quality. The use of anti-static edge-sealing tape eliminates the need for the U-shaped 3M double-sided shock-absorbing foam around the backlight assembly, reducing material costs and enhancing market competitiveness.

[0004] In existing technologies, the structure of an in-vehicle display screen consists of a cover glass, a front-mounted display (FOG), a backlight module, a deserializing plate, a mounting bracket, a plastic back cover, and a rear enclosure. The cover glass, FOG, and backlight module constitute the display module. The backlight module's surrounding walls are fixed to the cover glass using structural adhesive. The deserializing plate and mounting bracket are fixed to the backlight backplate with screws, and then installed into the plastic back cover. The plastic back cover is fixed to the backlight using structural adhesive. Finally, the rear enclosure is assembled. Because the backlight surrounding walls are fixed to the cover glass using structural adhesive, and the mounting bracket for the vehicle is fixed to the backlight backplate, the entire weight and structural strength of the display screen depend on the strength of the backlight backplate. Therefore, for low-cost display screens, the backlight backplate generally adopts a die-cast structure with a main wall thickness of 1.8T or more. Utility Model Content

[0005] The present invention aims to provide a vehicle-mounted display screen structure that reduces material costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vehicle display screen structure, including a rear shell and a cover glass, wherein a groove platform is provided on the rear shell, the cover glass is fitted into the groove platform, a structural adhesive for fixing the cover glass is provided in the groove platform, and a FOG and a backlight are provided between the rear shell and the cover glass.

[0007] The FOG is positioned between the backlight and the cover glass, and neither the backlight nor the FOG comes into contact with the recessed platform.

[0008] A deserialization plate is provided between the backlight and the rear cover.

[0009] The backlight and the rear shell are connected by structural adhesive.

[0010] The rear shell is provided with a bracket, and the bracket and the rear shell are an integral structure.

[0011] The bracket is fitted with a rear cover.

[0012] The unscrewing board is equipped with a plug that mates with the rear shell.

[0013] A backlight foam is provided between the FOG and the backlight.

[0014] The technical advantages of this invention are as follows: The integrated design of the die-cast back cover and mounting bracket saves the cost of developing a separate mounting bracket. Since the strength of the display screen is mainly concentrated in the die-cast back cover, the backlight and cover glass are structurally relatively isolated. Both the cover glass and the backlight are directly fixed inside the die-cast back cover. The backlight's backplate uses a 0.8T or even 0.5T 5052 aluminum alloy sheet metal structure. Using 5052 aluminum alloy sheet metal for the backlight's backplate provides better heat dissipation, allowing for the use of more LEDs to increase brightness, saving DBEF film material and reducing material costs. There is no structural adhesive between the backlight module and the cover glass + FOG; only foam is used for positioning, simplifying the display module assembly, helping to improve the display module's production yield and reduce costs.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0020] Please see Figure 1-2 A vehicle-mounted display structure includes a rear shell 1 and a cover glass 2. The rear shell 1 has a recessed platform 3, and the cover glass 2 is fitted into the recessed platform 3. Structural adhesive is provided in the recessed platform 3 to fix the cover glass 2. A FOG 4 and a backlight 5 are provided between the rear shell 1 and the cover glass 2. The cover glass 2 is directly connected to the rear shell 1 by structural adhesive. The backlight 5 and the cover glass 2 are directly fixed to the rear shell 1, dispersing the connection pressure. By reducing the load pressure on the backlight 5, the backplate of the backlight 5 can adopt a thinner structure, reducing material costs. Furthermore, because the backplate of the backlight 5 is thinner, heat dissipation performance can be improved. More LEDs can be added to increase brightness without increasing the overall heat. Moreover, by adding more LEDs to increase brightness, DBEF film material can be saved. The same brightness effect can be achieved by adding inexpensive LEDs, reducing material costs.

[0021] FOG4 is positioned between the backlight 5 and the cover glass 2, and neither the backlight 5 nor FOG4 contacts the recessed platform 3. FOG4 is connected to the backlight 5, which is positioned on the back cover 1, so that the backlight 5 and the cover glass 2 are separately connected to the back cover 1, thus reducing the strength required for the connection between the backlight 5 and the back cover 1 and also reducing the pressure required for the backlight 5.

[0022] A deserialization plate 6 is provided between the backlight 5 and the rear shell 1 to support and connect the backlight 5.

[0023] The backlight 5 and the back cover 1 are connected by structural adhesive; the backlight 5 is fixed to the back cover 1 by structural adhesive, forming the effect that the back cover 1 is connected to the backlight 5 and the glass 2 cover plate respectively.

[0024] The rear shell 1 is equipped with a bracket 7, and the bracket 7 and the rear shell 1 are an integral structure. The die-cast rear shell 1 and the mounting bracket 7 are integrated into one design, which saves the cost of developing the mounting bracket 7 separately. The material can be alloys such as ADC12 or AZ91 D.

[0025] A rear cover 8 is fitted onto the bracket 7 to assist in fixing and installing the rear cover 1.

[0026] The unscrewing board 6 is provided with a plug 9 that mates with the rear shell 1; used for installing the unscrewing board 6.

[0027] A backlight foam 10 is provided between FOG4 and backlight 5; it serves to prevent dust from entering between backlight 5 and FOG4.

[0028] The technical advantages of this utility model are as follows: The integrated design of the die-cast back shell 1 and the mounting bracket 7 saves the cost of developing the mounting bracket 7 separately. Since the strength of the display screen is mainly concentrated on the die-cast back shell 1, the backlight 5 and the cover glass 2 are structurally relatively isolated. Both the cover glass 2 and the backlight 5 are directly fixed inside the die-cast back shell 1. The backplate of the backlight 5 uses a 0.8T or even 0.5T 5052 aluminum alloy sheet metal structure. Using 5052 aluminum alloy sheet metal for the backlight 5 provides better heat dissipation, allowing for the use of more LEDs to increase brightness, saving DBEF film material and reducing material costs. There is no structural adhesive between the backlight 5 module and the cover glass 2+FOG4; only foam is used for positioning, simplifying the display module assembly, helping to improve the production yield of the display module, and reducing costs.
