Mounting structure of vehicle-mounted display screen

Technical Field

The utility model relates to an on-vehicle display screen specifically indicates an on-vehicle display screen's mounting structure.

Background

Along with car audio-visual entertainment system function is more and more powerful, and user's demand is more and more high for the display screen size is bigger and bigger, and the frame is littleer and more, and the laminating is gone up to full laminating and is replaced original frame subsides gradually on the laminating mode, and the structural design degree of difficulty is increasing more and more, thereby can't guarantee the good performance of display screen at original structure, the mechanical structure of display screen needs optimization innovation just can adapt to new display screen requirement.

The common size of the common vehicle-mounted display screen is 4-8 inches, most of the frames exceed 15mm, the frame pasting mode is adopted, the common size of the new display screen is more than 10 inches, the frames are controlled within 10mm, and the pasting mode adopts full pasting.

The conventional vehicle-mounted display screen assembly generally comprises a touch screen (TP), a display screen module (TFT), a rear cover and other necessary structural components. In the past, a small-sized display screen is usually finished by firstly adhering a touch screen and a display screen module with a square adhesive tape (namely, frame adhesion) and then adhering a double-sided adhesive tape or fixing screws on the edge of the display screen module and a rear cover, so that the frame is required to be wide, the screws are arranged in a sufficient space, or the width of the double-sided adhesive tape is ensured.

On the one hand, the existing display screen with large size and narrow frame is completely laminated with the touch screen and the display screen module glue; on the other hand, display screen module frame space is limited, is not enough to arrange set screw or ensures sufficient double faced adhesive tape, and the frame is fixed can not provide sufficient installation intensity, just must install fixedly at display screen module back middle zone design mounting point this moment, and the common mode all is that display screen module back takes the metal reference column, and the cooperation is connected fixedly with screw and back lid.

However, if the holes are directly formed in the rear cover to fix the screws, local stress of the display area of the display screen module at the positions of the screws is too large, and the display effect is affected due to the unevenness of the screen; the risk that the OCA glue between the display screen module and the touch screen is stressed too much and unevenly can be caused. Therefore, it is desirable to find a mounting structure for a vehicle-mounted display panel that can minimize local stress applied to a display panel module (TFT) while providing mounting strength.

Disclosure of Invention

The utility model aims at solving the above-mentioned background art not enough, provide a simple structure, reduce the on-vehicle display screen mounting structure of screw department local stress.

The technical scheme of the utility model is that: the utility model provides a mounting structure of on-vehicle display screen, includes display screen module, back lid, its characterized in that:

the display screen module is characterized in that a plurality of studs are arranged on the back of the display screen module, a gap is formed in the back cover to form an ear-shaped elastic sheet corresponding to each stud, the root of the ear-shaped elastic sheet is connected to the back cover, a mounting hole is formed in one end, far away from the root, of the ear-shaped elastic sheet, and a screw penetrates through the mounting hole and is fixedly connected with the studs.

Preferably, the ear-shaped elastic piece comprises a long strip part extending outwards from the root part and a round part formed by extending the end part of the long strip part in an expanding way, and the mounting hole is positioned on the round part.

Further, the circular part is sunken to form a sinking platform, and the mounting hole is located at the bottom of the sinking platform.

Further, the gap comprises a first linear gap and a second linear gap which are arranged in parallel to form a long strip portion, and an arc-shaped gap which enables the end portions of the first linear gap and the second linear gap to be communicated to form a circular portion.

Preferably, each ear-shaped elastic sheet is symmetrically arranged on the rear cover along the Y direction of the vehicle body.

The utility model has the advantages that:

1. the ear-shaped elastic sheet can be provided with a screw to provide fixing strength and longitudinal elasticity for a fixed position, the two elastic sheets are matched to realize flexible installation between the display screen module (TFT) and the rear cover, the local stress at the screw position is prevented from being too large, and the good display effect of the display screen and the stable bonding between the display screen module and the touch screen are ensured.

2. On the premise of not changing the large surface of the rear cover die, the flexible adjustment of the installation flexibility can be realized only by adjusting the size of the gap in the loading process; the space of the frame fixing screw is saved, so that the space of the model and the environment part is more advantageous.

3. This structure can be according to the space condition, and even nimble distribution is in the display screen back, and furthest's reduction screw structure is to the local stress influence of display screen module.
