Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and more particularly to display devices used in thermal alternating environments. Background Technology

[0002] Control equipment typically includes a console, which usually houses a display device. The typical application of this display device is to display various data, parameters, and / or provide various video images. It is also configured for touch response to control related equipment. The display device mounted on the console typically includes: a housing with a rectangular receiving slot, a display module housed within the housing, and a cover plate covering the display module. This cover plate is usually configured as a display panel or a touch-sensitive display panel.

[0003] In existing technologies, the edges of the cover plate are typically rigidly fixed to the end face of the control panel or housing using adhesive bonding or fastener clamping. However, this rigid fixing method has the following drawbacks in operating environments with alternating hot and cold temperatures:

[0004] Temperature changes caused by alternating hot and cold temperatures generate thermal stress inside the cover plate. If the edges of the cover plate are fixed, the thermal stress can easily cause the cover plate to warp and deform. This warping and deformation may cause display defects on the one hand, and cause stress concentration at the fixed connection on the other hand. This stress concentration may cause the cover plate, which is fixed by adhesive, to separate from the adhesive. This stress concentration may cause the cover plate, which is fixed by fasteners, to bulge and deform. Summary of the Invention

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0039] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0040] like Figure 1 and Figure 2 As shown, the present invention discloses a display device for installation at a control console 100, which may be the dashboard of a moving vehicle and is typically in a thermally alternating environment. The control console 100 has a tabletop 101, on which a recess 102 is formed, and the edge of the recess 102 is formed with a stepped surface 103.

[0041] The display device includes a display module 10, a support shell 20, a cover plate 30, and a limiting plate 70. The recess 102 is adapted to the support shell 20, and the support shell 20 is adapted to the shape of the display module 10. For example, if the shape of the display module 10 is rectangular, the recess 102 and the support shell 20 are configured as a rectangular structure. The main body of the support shell 20 is embedded in the recess 102. The support shell 20 has an outwardly flared outer edge plate 21, which overlaps the stepped surface 103.

[0042] The display module 10 is disposed in the main body of the carrier housing 20. The display module 10 includes: a screen body 11 for display, a backlight panel 12 disposed on the back of the screen body 11 for providing light, and an encapsulation housing 13 having a receiving groove and a display port 14 opposite to the receiving groove. The screen body 11 and the backlight panel 12 in the assembled state are disposed in the encapsulation housing 13 as a whole, and the area of ​​the screen body 11 corresponding to the display port 14 forms a display area.

[0043] The cover plate 30 is configured to be transparent. The cover plate 30 may be made of polymer and configured to be heat resistant. The cover plate 30 covers the outside of the display module 10 and makes a certain gap between the cover plate 30 and the screen body 11 in the display module 10, thereby allowing the cover plate 30 to have a certain amount of movement in its thickness direction.

[0044] The edge of the cover plate 30 is opposite to the outer edge plate 21 of the aforementioned bearing shell 20. The limiting plate 70 is disposed on the outer side of the cover plate 30 in the thickness direction. A hollow portion is provided in the middle region of the limiting plate 70. This hollow portion corresponds to the display port 14 of the encapsulation shell 13 of the display module 10. In this way, the limiting plate 70 will not block the display module 10. The side region 71 of the edge of the hollow portion corresponds to the edge of the cover plate 30, thereby limiting the cover plate 30 so that the cover plate 30 is in the assembled state, thereby preventing the cover plate 30 from separating from the display module 10.

[0045] The outer surface of the limiting plate 70 is configured to have the same structure as the table surface 101 of the control console 100, so that the outer surface of the limiting plate 70 also serves as the table surface 101. The limiting plate 70 can be fixed to the control console 100 by a bayonet, adhesive, or built-in fasteners.

[0046] In this invention, a liner 40 and an elastic bend 50 are provided between the edges of the outer edge plate 21 and the cover plate 30; both the liner 40 and the elastic bend 50 extend synchronously along the side direction of the cover plate 30, thus the liner 40 and the elastic bend 50 are generally elongated structures. The bottom surface of the liner 40 is attached and fixed to the outer edge plate 21, for example, by adhesive or countersunk screws.

[0047] like Figure 2As shown, the cross-sectional structure of the elastic bending plate 50 includes: a first horizontal portion 51 and a second horizontal portion 52 facing opposite directions, and a bent portion 53 between the first horizontal portion 51 and the second horizontal portion 52 and integrally formed with the first horizontal portion 51 and the second horizontal portion 52. The first horizontal portion 51 is located above, and the second horizontal portion 52 is located below. The second horizontal portion 52 is fixed between the outer edge plate 21 and the liner plate 40. The first horizontal portion 51 is attached and fixed to the bottom of the cover plate 30. In this state, the first horizontal portion 51 is higher than the upper plate surface of the liner plate 40. Thus, the cover plate 30 is flexibly connected to the outer edge portion through the elastic bending plate 50.

[0048] When the display device is in a thermally alternating environment, the cover plate 30 generates thermal stress. The expansion / contraction of the cover plate 30 caused by thermal stress can be accommodated by the elastic deformation of the aforementioned elastic bending plate 50, thereby effectively preventing warping deformation caused by thermal stress under rigid connection conditions. In addition, since the first horizontal portion 51 is higher than the upper surface of the liner plate 40, there is a certain gap between the cover plate 30 and the liner plate 40. This gap is used to accommodate the deformation of the various components in the display device in the thickness direction.

[0049] like Figure 3 and 4 and combined Figure 2 As shown, in some more preferred structures of the elastic bending plate 50, a plurality of through slots are integrally formed on the second horizontal portion 52 and the bending portion 53 of the elastic bending plate 50. These through slots are spaced apart along the length of the elastic bending plate 50, so that elastic arms 55 are formed on the elastic bending plate 50 and spaced apart along the length. A plurality of slots 42 are formed at the bottom of the liner plate 40, extending to the side end face of the liner plate 40. The elastic arms 55 are inserted into the slots 42 from the side end face. Thus, the second horizontal portion 52 of the elastic bending plate 50 can be fixed between the liner plate 40 and the outer edge plate 21 by a plug-in connection. Furthermore, the bending portion 53 of the elastic bending plate 50 is cut with spaced elastic arms 55, which helps to reduce the internal stress of the bending portion 53 during elastic deformation.

[0050] In some more preferred structures of the elastic bending plate 50, a balancing plate portion 54 is formed in the opposite direction of the first horizontal portion 51, which makes the junction area between the bending portion 53 and the first horizontal portion 51 located in the middle, which is beneficial to improve the stress situation between the elastic bending plate 50 and the cover plate 30.

[0051] like Figure 3 and 4 and combined Figure 2As shown, some preferred embodiments of the present invention also include a support member between the cover plate 30 and the liner plate 40. The support member includes two hollow components 60 arranged in parallel and spaced apart, which extend synchronously along the side of the cover plate 30. Specifically, the cross-sectional structure of each hollow component 60 includes: a top wall 61, a bottom wall 62, and two side walls 63 between the top wall 61 and the bottom wall 62. The two side walls 63 have symmetrically arranged inwardly curved portions 631. Spaced and parallel embedding grooves 41 are provided on the liner plate 40. The lower part of each hollow component 60 is correspondingly disposed in the embedding groove 41, and the bottom wall 62 is bonded and fixed to the bottom of the embedding groove 41. The top wall 61 of the hollow component 60 is used to support the cover plate 30 but is not connected to the cover plate 30. Thus, the hollow component 60, in conjunction with the elastic bending plate 50, supports the cover plate 30. Furthermore, by deforming at the inner bend 631 of the side wall 63, the hollow component 60 deforms in the thickness direction, thereby adapting to the displacement of the cover plate 30 in the thickness direction. Additionally, this hollow component also provides a sealing effect on the interior of the display area and enhances the bending stiffness of the central region of the cover plate 30 corresponding to the display area.
