Description

Technical Field

[0001] The present disclosure relates to the technical field of electronic equipment, and in particular to a terminal device. Background Art

[0002] The terminal device usually includes a screen module and a middle frame. The screen module is used to display images, and the middle frame is used to support the screen module and other components.

[0003] Generally, the screen module includes various stacked functional film layers, such as a cover plate and a panel, etc. The cover plate and the panel are both flat structures, the edge of the middle frame forms a bulge toward the cover plate, the end of the bulge is connected to the edge of the cover plate, and the panel and other functional film layers are arranged in the cavity formed between the cover plate and the middle frame, and are attached to the cover plate.

[0004] Due to the requirement for current terminal devices to have narrow bezels, the gap between the edge of the panel and the protrusion of the middle frame is smaller. When the terminal device collides or falls, there may be a certain misalignment between the protrusion and the cover plate, causing the inner surface of the protrusion to hit the edge of the panel and other film layers, thereby causing a gap between the panel and other film layers, resulting in black spots on the panel, and then causing the panel to fail, reducing the service life and stability of the terminal device.

[0036] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0037] The present disclosure provides a terminal device, see Figure 1 The terminal device includes a middle frame 1 and a screen module 2.

[0038] The middle frame 1 supports other components in the terminal device, facilitating the assembly of other components.

[0039] The screen module 2 is used to display images. The middle frame 1 has a flat structure, and the screen module 2 is located on one side of the middle frame 1 and is connected to the middle frame.

[0040] The screen module 2 may include a cover plate 21 and a panel 22 .

[0041] The cover plate 21 may be a glass cover plate. Of course, its material may also be other reasonable materials, which is not limited in the embodiments of the present disclosure.

[0042] The cover plate 21 has a flat plate portion 211 and a flange 212 located at the edge of the flat plate portion 211 and facing the middle frame 1, and the flange 212 is connected to the middle frame 1. That is, the flat plate portion 211 has a flat plate structure, the flange 212 is located at the edge of the flat plate portion 211, and the flange 212 protrudes in the direction of the middle frame 1.

[0043] The flat plate portion 211 and the flange 212 are an integrally formed structure. In a possible implementation, a smooth transition can be made between the flat plate portion 211 and the flange 212 , that is, an arc surface or a rounded corner can be provided at the position where the flat plate portion 211 and the flange 212 are connected.

[0044] In a possible implementation, the flat plate portion 211 may be a flat plate structure of any reasonable shape, for example, a square flat plate structure or a circular flat plate structure, etc., which is not limited in the embodiment of the present disclosure.

[0045] Regarding the flange 212, the edge of the flat plate portion 211 may have the flange 212 only in a partial position. For example, when the flat plate portion 211 is a square flat plate structure, the flange 212 may be provided only on the edges of two sides, and the other two sides may not have the flange 212. Alternatively, the flange 212 may be provided only on the edges of three sides, and the remaining one side may not have the flange 212. Alternatively, the flange 212 may be provided on a partial edge of one side, and the remaining part of the side may not have the flange 212, and so on. It can be set according to the actual structure and requirements of the terminal device, and the embodiments of the present disclosure are not limited to this.

[0046] The panel 22 is provided with a plurality of light emitting units, which display images. The panel is also generally referred to as a panel.

[0047] The panel 22 is located in the cavity 3 formed between the flat portion 211, the flange 212 and the middle frame 1, and is connected to the flat portion 211. The panel 22 may also have a flat plate structure, and may be located on a side of the flat portion 211 close to the middle frame 1, and be attached to and connected to a seventh surface g of the flat portion 211 close to the middle frame 1 (also referred to as a surface of the flat portion 211 close to the cavity 3).

[0048] It can be understood that, in the vertical direction of the plane where the panel 22 is located, the length of the flange 212 is greater than the length of the panel 22 (the length of the panel 22 in the vertical direction of the plane where the panel 22 is located can also be called the thickness of the panel 22). In this way, it can be ensured that the flange 212 can wrap and protect the edge of the panel 22, thereby preventing the edge of the panel 22 from being hit by other components.

[0049] In summary, in the terminal device provided by the present invention, since the flat portion 211 and the flange 212 of the cover plate 21 are an integrally formed structure, when the terminal device collides or falls, there will be no relative misalignment between the flat portion 211 and the flange 212, and the edge of the panel 22 will not be hit, thereby avoiding the problem of black spots on the panel 22 caused by the edge of the panel 22 being hit, thereby improving the service life of the panel 22. In addition, the flange 212 of the cover plate 21 is equivalent to wrapping and protecting the panel 22, further improving the service life of the panel 22, thereby improving the service life and stability of the terminal device.

[0050] Moreover, compared to the plastic middle frame commonly used in the related art, the flange 212 in the embodiment of the present disclosure is generally made of glass material, which has a harder property than the plastic middle frame, thereby further improving the protective effect of the flange 212 on components such as the panel 22 and improving the service life of the panel 22, thereby improving the service life and stability of the terminal device.

[0051] Several possible connection structures between the flange 212 and the middle frame 1 are introduced below:

[0052] In a possible implementation, the edge of the middle frame 1 may also have a flange, and the flange of the middle frame 1 is located on the side of the flange 212 of the cover plate 21 away from the cavity 3, and the inner surface of the flange of the middle frame 1 (that is, the surface close to the cavity) is connected to the first surface a of the flange 212 away from the cavity 3.

[0053] In this way, when the terminal device collides or falls, even if there is a relative misalignment between the flange of the middle frame 1 and the flange 212 of the cover plate 21, due to the spacing of the flange 212, the flange of the middle frame 1 will not hit the edge of the panel 22, thereby wrapping and protecting the panel 22, thereby improving the service life of the panel 22, thereby improving the service life and stability of the terminal device.

[0054] In the embodiment of the present disclosure, the flange of the middle frame 1 and the flange 212 of the cover plate 21 may be connected by adhesive. Of course, other reasonable connection methods may also be used, and the embodiment of the present disclosure is not limited to this.

[0055] In another possible implementation, see Figure 1 and Figure 2 The end surface 212a of the flange 212 away from the flat plate portion 211 is attached to and connected to the middle frame 1.

[0056] Furthermore, the first surface a of the flange 212 away from the cavity 3 is flush with the third surface c of the middle frame 1 away from the cavity 3 (also referred to as the outer wall of the middle frame 1), wherein the first surface a and the third surface c are both perpendicular to the plane where the panel 22 is located. In this structure, the screen frame of the terminal device is the distance between the position of the panel 22 where the image is not displayed and the plane where the first surface a is located, that is, Figure 1 As for d1 in the figure, it can be understood that the position of the panel 22 where no image is displayed can be understood as the position on the panel 22 close to the edge where no light-emitting unit is set. Therefore, d1 can be the sum of the length of the panel 22 where no light-emitting unit is set and the distance between the edge of the panel 22 and the first surface a.

[0057] Since the screen border only needs to consider the length of the panel 22 where the image is not displayed and the distance between the edge of the panel 22 and the first surface a of the flange 212 away from the cavity 3, and since there is no need to consider the assembly tolerance between the cover plate 21 and the middle frame 1 in the related technology and the distance when relative misalignment occurs between the two, the terminal device provided by the present invention reduces the length of the screen border and better meets the current demand for narrow borders for terminal devices.

[0058] Furthermore, while reducing the length of the screen frame, the smoothness of the side walls of the overall structure of the terminal device is ensured, thereby improving the aesthetic appearance of the terminal device and enhancing the user experience.

[0059] Similarly, the flange 212 in this structure also wraps and protects the panel 22 and other components, thereby increasing the service life of the panel 22 and thus increasing the service life and stability of the terminal device.

[0060] In one possible implementation, see Figure 3 and Figure 4 The end of the flange 212 away from the flat plate portion 211 may have a notch 2121, and correspondingly, the edge of the middle frame 1 has a protrusion 11, which is located in the notch 2121 and connected to the inner side wall of the notch 2121. It can be understood that Figure 3 In the figure, the protrusion 11 in the center frame 1 and other parts except the protrusion 11 are divided by a dotted line.

[0061] That is, when connecting the middle frame 1 and the cover plate 21, in addition to attaching and connecting the end face 212a of the flange 212 to the middle frame 1, the inner side wall of the notch 2121 is also attached and connected to the surface of the protrusion 11 set on the middle frame 1, thereby further improving the connection strength between the middle frame 1 and the cover plate 21, thereby improving the stability of the terminal device.

[0062] In one possible implementation, see Figure 3 and Figure 4 The first surface a of the flange 212 away from the cavity 3, the second surface b of the protrusion 11 away from the cavity 3, and the third surface c of the middle frame 1 away from the cavity 3 are all flush, wherein the first surface a, the second surface b and the third surface c are all perpendicular to the plane where the panel 22 is located.

[0063] In this way, the protrusion 11 and the notch 2121 set in the terminal device will not affect the length of the screen border d1, and the length of the screen border d1 can still be ensured to be short, thereby meeting people's demand for a narrow border of the terminal device.

[0064] Furthermore, while reducing the length of the screen frame, the smoothness of the side walls of the overall structure of the terminal device is ensured, thereby improving the aesthetic appearance of the terminal device and enhancing the user experience.

[0065] The notch 2121 may have a variety of forms. For example, the notch 2121 may have only one side opening, that is, it may be provided in the form of a groove on the end surface 212a of the flange 212 away from the flat portion 211, and one side opening is located on the end surface 212a (not shown in the figure). For another example, the notch 2121 may have two side openings, and the two side openings may be respectively located on the end surface 212a and the first surface a of the flange 212 away from the cavity 3 (see Figure 3 and Figure 4 As shown), etc., the position and shape of the notch 2121 on the flange 212 can be set according to actual needs, and the embodiment of the present disclosure is not limited to this.

[0066] In the embodiment of the present disclosure, the end surface 212a of the flange 212 and the middle frame 1, as well as the protrusion 11 and the inner wall of the notch 2121 can be connected by adhesive. Of course, other reasonable connection methods can also be used, and the embodiment of the present disclosure is not limited to this.

[0067] In one possible implementation, the thickness of the portion of the flange 212 between the plane where the fourth surface d is located and the plane where the fifth surface e is located is less than or equal to the thickness of the flat plate portion 211, wherein the fourth surface d is the surface of the panel 22 away from the flat plate portion 211, and the fifth surface e is the surface of the flat plate portion 211 away from the cavity 3, and the fourth surface d and the fifth surface e are both parallel to the plane where the panel 22 is located.

[0068] See also Figure 5 , the plane where the fourth surface d lies is Figure 5 The plane m in the figure, the plane where the fifth surface e lies is Figure 5 The portion of the flange 212 between the plane where the fourth surface d is located and the plane where the fifth surface e is located is Figure 5 The portion between plane m and plane n, Figure 5 Where d2 is the thickness of one of the flanges 212 of the listed portion, and the thickness of the flat plate portion 211 is Figure 5 d3 in .

[0069] In the embodiment of the present disclosure, d2 can be less than or equal to d3. In this way, while ensuring the strength of the flange 212, its thickness is kept as small as possible, thereby reducing the length of the screen frame and meeting people's demand for a narrow frame of the terminal device.

[0070] In one possible implementation, see Figure 1 , Figure 3 and Figure 5 In addition to the panel 22, the screen module 2 may also include other functional film layers. For example, the screen module 2 may also include functional film layers such as a polarizer 23, a back plate 24, a foam 25 and a copper foil 26. The cover plate 21, the polarizer 23, the panel 22, the back plate 24, the foam 25 and the copper foil 26 are stacked and connected in sequence. Of course, the screen module 2 may include any combination of the above functional film layers, and may also include any other reasonable functional film layers, which is not limited in the embodiments of the present disclosure.

[0071] When the above-mentioned functional film layers are provided, the following settings can be made: the thickness of the portion of the flange 212 between the plane where the eighth surface is located and the plane where the fifth surface e is located is less than or equal to the thickness of the flat portion 211, wherein the eighth surface is the surface of the copper foil 26 away from the flat portion 211, the fifth surface e is the surface of the flat portion 211 away from the cavity 3, and the eighth surface and the fifth surface e are both parallel to the plane where the panel 22 is located.

[0072] See also Figure 5 , the plane where the eighth surface is located is Figure 5 The portion of the flange 212 between the plane where the eighth surface is located and the plane where the fifth surface e is located is Figure 5 The part between plane n and plane k in .

[0073] In this way, while ensuring that the flange 212 wraps and protects the functional film layers such as the panel 22, the polarizer 23, the back panel 24, the foam 25 and the copper foil 26, the thickness thereof is reduced as much as possible, thereby reducing the frame length of the terminal device.

[0074] In a possible implementation, the thickness of the end of the flange 212 away from the flat plate portion 211 is greater than or equal to the thickness of the flat plate portion 211 .

[0075] See also Figure 5 The end of the flange 212 away from the flat plate portion 211 may be a portion between the plane k and the end surface 212a of the flange 212. Figure 5 The d4 in the figure is the thickness of one of the flanges 212 of the listed part.

[0076] Since a notch 2121 needs to be provided at the end of the flange 212 away from the flat portion 211, in order to improve the strength of the end, its thickness d4 is set to be greater than or equal to the thickness of the flat portion 211, that is, greater than or equal to the thickness of the flange 212 between plane n and plane k, thereby improving the strength of the flange 212 and the connection strength between the flange 212 and the middle frame 1.

[0077] The above are only several possible connection structures between the flange 212 and the middle frame 1. The connection structure between the flange 212 and the middle frame 1 in the embodiment of the present disclosure may also be any other reasonable structure, and the embodiment of the present disclosure is not limited to this.

[0078] In one possible implementation, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The terminal device may further include a light shielding film layer 4, which is attached to and connected to the sixth surface f of the flange 212 close to the cavity 3, wherein: Figure 1 and Figure 6 A light shielding film layer 4 is added.

[0079] Since the cover plate 21 is usually made of transparent material, a shading film layer 4 is provided to shield the components inside the cover plate 21, for example, the panel 22, polarizer 23, back plate 24, foam 25 and copper foil 26 arranged in the cavity 3 can be shielded, thereby improving the aesthetics of the terminal device and improving the user experience.

[0080] In one possible implementation, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The light shielding film layer 4 is attached to and connected with the portion of the seventh surface g of the flat plate portion 211 near the edge, wherein the seventh surface g is the surface of the flat plate portion 211 near the cavity 3. The portion of the seventh surface g near the edge may be directly opposite to the portion of the panel 22 where no light emitting unit is provided.

[0081] That is, the shading film layer 4 not only blocks the sixth surface f, but also blocks the portion of the seventh surface g near the edge. In this way, the shading film layer 4 not only blocks the transparent flange 212, but also can block the portion of the panel 22 where no image will be displayed, thereby further improving the aesthetics of the terminal device and enhancing the user experience.

[0082] In the embodiment of the present disclosure, the material of the shading film layer 4 can be ink, and the ink can be applied on the sixth surface f and the seventh surface g near the edge to form the shading film layer 4. Of course, it can also be other reasonable shading materials or shielding materials, and the embodiment of the present disclosure does not specifically limit this.

[0083] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0084] The disclosed embodiment provides a terminal device. Since the flat plate portion 211 and the flange 212 of the cover plate 21 are an integrally formed structure, when the terminal device collides or falls, there will be no misalignment between the flat plate portion 211 and the flange 212, and there will be no collision with the edge of the panel 22. The cover plate 21 is equivalent to wrapping and protecting the panel 22, thereby increasing the service life of the panel 22 and improving the service life and stability of the terminal device.

[0085] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
