Description

Technical Field

[0001] This utility model relates to the field of displays, and in particular to an improved in-vehicle display module for Mura. Background Technology

[0002] With the development of the automotive industry and the continuous improvement of driving experience, the use of large-size LCD screens in in-vehicle instrument panels has become very common. Among these, the instrument panel display module structure is gradually being promoted by OEMs. It is assembled from a cover plate, optical adhesive, FOG (focal element design), sheet metal backlight, connecting adhesive, and instrument panel frame. The frame connects both the cover plate and the sheet metal backlight bottom surface using connecting adhesive. Due to differences in the curing time and material of the connecting adhesive, there will be vertical pulling forces between the frame and the display components. Alternatively, after the adhesive cures, if the plastic frame deforms due to the screw assembly, the deformation force is directly transmitted to the frame or display components, causing malfunctions on the display screen. Utility Model Content

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] This invention improves upon Mura's in-vehicle display module by comprising a display component, an in-vehicle frame, and at least one sponge strip. The in-vehicle frame has a receiving groove in which the display component is fixed. A sponge groove corresponding to the sponge strip is formed on the bottom surface of the receiving groove, and the sponge strip is embedded in the sponge groove, with the thickness of the sponge strip exceeding the depth of the sponge groove.

Attached Figure Description

[0017] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the embodiments will be briefly described below.

[0018] Figure 1 This is an exploded view of the improved Mura vehicle display module according to one embodiment of the present invention.

[0019] Figure label:

[0020] Display component 10, cover plate 11, FOG display screen 12, backlight component 13, optical adhesive 14, vehicle frame 20, connecting adhesive 21, sponge strip 30. Detailed Implementation

[0021] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0022] This application proposes an improved in-vehicle display module for Mura; please refer to [link / reference]. Figure 1 The system includes a display component 10, a vehicle-mounted mid-frame 20, and a foam strip 30. The display component 10 displays the image and is electrically connected to the vehicle's infotainment system. The vehicle-mounted mid-frame 20 is mounted on the vehicle. The vehicle-mounted mid-frame 20 has a receiving groove. The display component 10 includes a display side and a backlight side, with the backlight side of the display component 10 fixed in the receiving groove. Because the assembly of the vehicle-mounted mid-frame 20 and the display component 10 generates stress, a foam groove corresponding to the foam strip 30 is formed on the bottom surface of the receiving groove. The foam strip 30 is embedded in the foam groove, and its thickness is greater than the depth of the foam groove, allowing it to protrude within the groove. This allows the foam strip 30 to elastically resist the backlight side of the display component 10, absorbing the stress generated during the assembly of the vehicle-mounted mid-frame 20 and the display component 10. This prevents stress transmission between the vehicle-mounted mid-frame 20 and the display component 10, making the overall structure more stable and improving its service life and reliability.

[0023] It should be noted that the sponge strip 30 is made of compressible sponge material and has elastic deformation properties. The elastic deformation is used to absorb the stress generated during the assembly of the vehicle frame 20 and the display component 10, and can provide support for the display component 10.

[0024] One side of the sponge strip 30 is adhesive, and the adhesive side of the sponge strip 30 is bonded to the bottom surface of the sponge groove, so that the sponge strip 30 is firmly embedded in the sponge groove, preventing the sponge strip 30 from falling out of the sponge groove or becoming displaced, which would affect the assembly of the vehicle frame 20 and the display component 10.

[0025] Preferably, the thickness of the sponge is 0.1mm-0.3mm greater than the depth of the sponge groove. If the thickness of the sponge is less than 0.1mm greater than the depth of the sponge groove, its stress absorption effect is minimal; if the thickness of the sponge is greater than 0.3mm greater than the depth of the sponge groove, the thickness of the sponge strip 30 is too large, affecting the assembly between the vehicle frame 20 and the display component 10.

[0026] Furthermore, the difference between the thickness of the sponge and the depth of the sponge groove is 0.25 mm.

[0027] Please refer to it again. Figure 1The improved Mura automotive display module also includes a connecting adhesive 21. The display component 10 is bonded to the bottom surface of the receiving groove of the automotive mid-frame 20 via the connecting adhesive 21, allowing the display component 10 to be firmly fixed to the automotive mid-frame 20. This prevents vibration from affecting the assembly between the automotive mid-frame 20 and the display component 10, further improving reliability. The backlight component 13 is also bonded to the bottom surface of the receiving groove via the connecting adhesive 21, enhancing the bond strength between the display component 10 and the automotive mid-frame 20. Preferably, the connecting adhesive 21 is an RTV adhesive or a hot melt adhesive. Depending on the curing time and material of the connecting adhesive, after the adhesive has cured, when the automotive mid-frame deforms due to screw assembly, the sponge strip can absorb or reduce the vertical pulling force between the automotive mid-frame and the display component, improving the reliability of the connection.

[0028] In one embodiment, there are two sponge strips 30, and two sponge grooves are respectively set on both sides of the bottom surface of the receiving groove. The sponge strips 30 are respectively fixed in the receiving groove. The sponge strips 30 on both sides of the receiving groove can further absorb the stress between the vehicle frame 20 and the display component 10, and the absorption is better.

[0029] In another embodiment, there are four sponge strips 30, and four sponge grooves are respectively set around the bottom edge of the receiving groove. The sponge strips 30 are fixed in the receiving groove, so that there are sponge strips 30 around the receiving groove to absorb the stress between the vehicle frame 20 and the display component 10, which has a stronger absorption capacity and further reduces the Mura between the vehicle frame 20 and the display component 10.

[0030] Please refer to it again. Figure 1 The display assembly 10 includes a cover plate 11, a FOG display screen 12, and a backlight assembly 13. The cover plate 11, the FOG display screen 12, and the backlight assembly 13 are stacked sequentially. The cover plate 11 includes a visible area and a non-visible area. The backlight assembly 13 is used to provide illumination for imaging of the FOG display screen 12, and the image displayed on the FOG display screen 12 can be displayed in the visible area of ​​the cover plate 11.

[0031] In addition, the display assembly 10 also includes optical adhesive 14, through which the cover plate 11 is bonded to the FOG display screen 12. The optical adhesive 14 has good light transmittance, ensuring that the image displayed on the FOG display screen 12 can be displayed in the visible area of ​​the cover plate 11.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
