Description

Technical Field

[0001] The utility model relates to the field of display screen technology, in particular to a central control display screen structure. Background Art

[0002] The in-vehicle central control display refers to a touchscreen display located between the driver's seat and the front passenger seat. It supports both image display and touch operation, enabling information display, control of various vehicle components, driver assistance, entertainment, and other related functions. As in-vehicle central control displays become increasingly powerful, they are also becoming larger, especially in large vehicles such as trucks, which have ample interior space to accommodate larger in-vehicle central control displays.

[0003] The vehicle-mounted central control display screen usually consists of two parts, such as a display device and a vehicle-mounted base; during actual installation, an installation space will be reserved between the main driver's seat and the co-driver's seat of the car; the display device is usually set on the display screen housing, and then the display screen housing is connected and installed with the vehicle-mounted base through multiple bolts. It generally requires tightening multiple bolts to tighten the connection between the two, and the installation speed is slow. Secondly, it is affected by the design of its own structure. Since there is no corresponding anti-fool-proof design between the two, this leads to the need to align the locking positions one by one during docking installation, which makes the installation operation cumbersome; and the display device itself has a poor heat dissipation effect, and the display screen will accumulate heat during long-term use.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0034] Please refer to Figures 1 to 5 As shown, it shows the specific structure of an embodiment of the present utility model.

[0035] In the description of the present invention, it should be noted that directional words, such as the terms "up", "down", "front", "back", "left", "right", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the drawings or during normal wear and use.

[0036] A central control display screen structure includes a vehicle-mounted base 10, a display screen 20 and a frame 30.

[0037] The vehicle-mounted base 10 is provided with an anti-mistake groove 11; a plurality of cross grooves 12 are provided on the side of the anti-mistake groove 11;

[0038] In this embodiment, the vehicle-mounted base is used to be installed and positioned at the central control position of the vehicle. Usually, a position for the vehicle-mounted base is reserved at the central control position. After the display screen is installed and positioned on the frame, the cross connection part on the frame is used to form an installation match with the cross groove on the vehicle-mounted base. During installation, the design of the anti-mock groove is conducive to the unique and determined plug-in direction, which can be convenient for the installer to plug in and prevent it from being plugged in incorrectly; to avoid repeated and long-term plugging and unplugging causing damage to the card structure and affecting the assembly.

[0039] The frame 30 includes an outer frame 31 and a bottom frame 32; the outer frame 31 and the bottom frame 32 form a mounting position; the display screen 20 is installed and positioned in the mounting position; the bottom of the outer frame 31 is provided with a cross connecting portion 33 adapted to the cross groove 12; the frame 30 is installed and positioned on the vehicle base 10 through the cooperation of the cross connecting portion 33 and the cross connecting groove; the display screen 20 includes a light guide plate 21, a heat dissipation layer 22 and a heat conductive layer 23; the heat dissipation layer 22 is provided on the lower surface of the light guide plate 21; the heat conductive layer 23 is provided on the outer surface of the second heat dissipation layer 22.

[0040] Preferably, the outer frame 31 and the base are respectively provided with a first heat dissipation hole 311 and a second heat dissipation hole 321. The first heat dissipation hole 311 is located beside the cross-connection portion 33. Heat generated by the display screen 20 during use can be discharged through the heat dissipation holes. In this embodiment, in subsequent applications, the central control display screen 20 can be cooled by a built-in heat dissipation component within the vehicle, such as a built-in fan or other heat dissipation method. The appropriate heat dissipation method can be selected according to actual needs and is not described in detail here.

[0041] Preferably, the upper surface of the light guide plate 21 is further provided with a diffusion film 24, a rear brightness enhancement film 25, and a front brightness enhancement film 26. These diffusion film 24, rear brightness enhancement film 25, and front brightness enhancement film 26 are sequentially arranged on the light guide plate 21 from bottom to top. When light passes through the brightness enhancement layer, it is evenly dispersed, reflected, and refracted, thereby increasing the brightness and uniformity of the entire display screen 20. This is achieved through the principle of optical diffuse reflection, which refracts light beams from all directions along the normal direction toward the display screen 20, concentrating the light and improving the brightness, ultimately enhancing the visual quality of the display screen 20 and the user experience.

[0042] Preferably, the upper surface of the front enhancement film 26 is also provided with a radiation shielding layer 27. This shielding layer 27 reduces the risk of radiation from the display screen 20 causing harm to the user. In this embodiment, the surface of the radiation shielding layer 27 is also provided with a graphene coating. Graphene is a two-dimensional material with unique properties, composed of a single layer of carbon atoms, and possesses extremely high electrical conductivity, thermal conductivity, and mechanical strength. The graphene coating on the display screen 20 utilizes its conductive properties and shielding effect to achieve radiation protection. When the display screen 20 is in motion, it generates subtle radiation, which the graphene coating absorbs and scatters, thereby reducing its impact on the human body. Furthermore, the high conductivity of graphene can also help the display screen 20 dissipate heat, reduce the impact of electromagnetic radiation on electronic components in the vehicle, and improve stability and reliability; in order to ensure that the graphene coating of the anti-radiation layer 27 does not affect the display effect, the graphene coating adopts a scattered coating form, that is, the graphene coating is distributed in the anti-radiation layer 27 with a certain laying density, avoiding the graphene coating from being laid in sheets, ensuring that the display screen can be viewed by the user through the anti-radiation layer 27.

[0043] Preferably, a barrier gap 34 is formed between the inner wall of the bottom frame 32 and the outer wall of the light guide plate 21. An elastic arm 35 is provided on the side of the inner wall of the bottom frame 32 facing the barrier gap 34. With the assistance of the elastic arm 35, a better fixation effect on the light guide plate 21 is achieved. Preferably, the elastic arm 35 includes an elastic contact portion 351 and a connecting portion. A hollow portion 352 is formed between the elastic contact portion 351 and a side surface of the connecting portion and the inner wall of the bottom frame 32. The design of the hollow portion 352 provides a larger range of elastic deformation, can accommodate a wider range of dimensional changes, and achieve a better fixation effect on the light guide plate 21. In this embodiment, an LED lamp is further provided on the side of the blocking gap 34 facing the light guide plate. When in operation, the light emitted by the LED lamp enters the light guide plate, and the white light is conducted in the light guide plate. A reflective film can be provided to conduct the light upward, and then the white light is evenly diffused through the diffusion film and the brightness enhancement film and then emitted, thereby realizing surface luminescence. The reflection principle is a well-known technology in the art and will not be elaborated here.

[0044] The design focus of the utility model is that it mainly uses the structural design and coordination of the vehicle base, display screen and frame, and the design of the anti-mock groove on the vehicle base to provide it with a unique and determined plug-in direction, which can be easily connected by the installer without plugging in the wrong direction.

[0045] Secondly, the cross slot and the cross connection part cooperate. The frame is installed and positioned on the vehicle base through the cooperation of the cross connection part and the cross connection slot; ensuring the connection between the display screen and the vehicle base is stable, and its installation speed is fast and convenient;

[0046] The last is the design of the heat dissipation layer and the heat conductive layer, which can discharge the heat generated by the light guide plate during use and dissipate it through the heat dissipation holes.

[0047] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
