[0032] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale.

[0033] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0034] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0035] like Figure 1 and Figure 2As shown, in order to promote the product concept of extreme lightness and thinness, the appearance of the display device is changed, and the lower edge of the cover 21 of the screen 2 is extended a certain distance to hide the hinge 3 between the screen 2 and the keyboard, so that the hinge 3 looks smaller in appearance, and the air outlet of the cooling fan 4 is moved to the side of the keyboard close to the lower edge of the cover 21 to discharge air, thereby forming a hidden appearance of the whole machine. However, during use of the display device, when the angle between the screen 2 and the keyboard is within a certain range (when the angle between the screen 2 and the keyboard is 135 degrees), the air blown out by the cooling fan 4 hits the screen 2 just, resulting in a higher temperature in this part. If the temperature accumulates further, it will affect the display effect of the screen 2.

[0036] Based on this, the present invention provides a display device. Figures 3 to 9 As shown, the display device includes a body 1 and a screen 2. An air outlet is provided on one side of the body 1. The screen 2 is rotatably connected to the body 1 through a rotating shaft 3. The area of ​​the screen 2 that can be swept by the wind from the air outlet is a heat dissipation zone. The screen 2 includes a cover plate 21, a support member 22 and a thermal pad 23. The side of the cover plate 21 close to the body 1 extends to completely block the rotating shaft 3. The support member 22 is provided on the back side of the cover plate 21. The thermal pad 23 is provided on the side of the support member 22 away from the cover plate 21 and is located in the heat dissipation zone. The rear shell 26 is provided on the side of the thermal pad 23 away from the cover plate 21.

[0037] The area of ​​the screen 2 that can be swept by the wind from the air outlet is the heat dissipation zone. A thermal pad 23 is provided at the position where the support member 22 is in the heat dissipation zone. A rear shell 26 is provided on the side of the thermal pad 23 away from the cover plate 21. The hot air blown into the heat dissipation zone conducts the heat to the support member 22, and then conducts the heat from the support member 22 to the thermal pad 23, and then conducts the heat from the thermal pad 23 to the rear shell 26. The heat is dispersed through the rear shell 26 to avoid temperature accumulation in the heat dissipation zone, which makes the temperature of the screen 2 higher, and affects the display effect of the screen 2.

[0038] The display device involved in the implementation mode of the present utility model is described in detail below with reference to specific embodiments.

[0039] See also Figure 1 and Figure 2 The display device may include a body 1, a screen 2 and a shaft 3, the screen 2 is rotatably connected to the body 1 via the shaft 3, the screen 2 includes a display module 25 and a cover 21, the cover 21 is arranged on the display side of the display module 25, and the side of the cover 21 close to the body 1 extends to completely block the shaft 3, but the hot air blown out of the air outlet of the cooling fan 4 will be blown onto the screen 2, resulting in a higher temperature in the area opposite to the screen 2 and the air outlet.

[0040] like Figure 3As shown, a support member 22 and a thermal pad 23 are provided between the cover plate 21 and the rear shell 26, the support member 22 is provided on the back of the cover plate 21, and the thermal pad 23 is provided on the side of the support member 22 away from the cover plate 21, and is located in the heat dissipation area of ​​the screen 2. It should be noted that the area of ​​the screen 2 that can be swept by the wind from the air outlet (not shown in the figure) is the heat dissipation area.

[0041] Because the effect of conductive heat dissipation is usually better than that of convective heat dissipation, the back cover 26 can be fitted with the thermal pad 23. However, the material of the thermal pad 23 is usually soft and easily deformed when subjected to force. After the thermal pad 23 is deformed, it will not fit well with the back cover 26, thereby reducing the heat dissipation performance of the screen 2. Therefore, a buffer pad 24 is added on both sides of the thermal pad 23. The buffer pad 24 mainly serves to support the thermal pad.

[0042] like Figures 4 to 9 As shown, the buffer pads 24 are arranged on both sides of the thermal pad 23 along the first direction, the first direction is the extension direction of the rotating shaft 3, the thickness of the buffer pad 24 is greater than the thickness of the thermal pad 23, and the rear shell 26 squeezes the buffer pad 24 and fits with the thermal pad. When the rear shell 26 and the thermal pad 23 are fitted, the buffer pad 24 is deformed first, and when the buffer pad 24 is deformed to a certain extent, the rear shell 26 and the thermal pad 23 are fitted, ensuring the contact effect between the thermal pad 23 and the rear shell 26.

[0043] like Figure 4 and Figure 5 As shown, the cover plate 21 includes a main body 211 and an extension 212, the extension 212 includes two first extensions 2121 and a second extension 2122, the two first extensions 2121 protrude from the main body 211, the second extension 2122 is located between the two first extensions 2121, the second extension 2122 protrudes from the first extension 2121, and the support member 22 is disposed on the second extension 2122. It can be understood that the distance between the first extension 2121 and the main body 211 along the second direction is smaller than the distance between the second extension 2122 and the main body 211 along the second direction, and the second direction is perpendicular to the first direction.

[0044] It should be noted that the first direction is Figure 4 The x direction is shown in Figure 4 The y direction shown in .

[0045] The edge of the main body 211 close to the rotating shaft 3 is the main body section 2101, the edge of the first extension section 2121 close to the rotating shaft 3 is the first extension section 2102, the edge of the second extension section 2122 close to the rotating shaft 3 is the second extension section 2103, and the edge of the cover plate 21 close to the rotating shaft 3 also includes a first arc-shaped recessed section 2104 and a second arc-shaped recessed section 2105, the first arc-shaped recessed section 2104 is respectively connected to the main body section 2101 and the first extension section 2102, and the second arc-shaped recessed section 2105 is respectively connected to the first extension section 2102 and the second extension section 2103. The edge of the cover plate 21 close to the rotating shaft 3 may also include an arc-shaped raised section 2106, one end of the arc-shaped raised section 2106 is connected to the first arc-shaped recessed section 2104, and the other end of the arc-shaped raised section 2106 is connected to the first extension section 2102.

[0046] The distance between the second extension section 2103 and the main section 2101 is greater than or equal to 5 mm, wherein the radius R1 of the first arc-shaped recessed section 2104 and the second arc-shaped recessed section 2105 is 4.0 mm, and the radius R2 of the arc-shaped raised section 2106 is 2.0 mm. While hiding the rotating shaft 3, the stiffness of the edge of the cover plate 21 can also be enhanced, which helps to buffer the stress generated by the edge collision, thereby achieving the function of protecting the edge of the cover plate 21 and the display module 25.

[0047] like Figure 6 and Figure 7 As shown, the length of the extension portion 212 in the second direction may not change, that is, the main section 2101 and the extension section are directly connected via the first arc-shaped recessed section 2104 .

[0048] like Figure 8 As shown, the support member 22 has two mounting portions 221, and the two mounting portions 221 are symmetrically arranged at both ends of the support member 22 along the first direction. The edge of the mounting portion 221 close to the extension portion 212 is retracted inward relative to the rest of the support member 22 in a direction away from the edge of the extension portion 212, and the edge of the mounting portion 221 close to the extension portion 212 is retracted inward relative to the rest of the support member 22, and the edge of the mounting portion 221 away from the extension portion 212 is convex in a direction away from the edge of the extension portion 212 relative to the rest of the support member 22.

[0049] The air outlet (not shown in the figure) includes two sub-air outlets, the heat dissipation area includes sub-heat dissipation areas that can be swept by the two sub-air outlets respectively, and the two mounting parts 221 are located at the positions of the sub-heat dissipation areas, each of which has a thermal pad 23, and buffer pads 24 are respectively provided on both sides of the two thermal pads 23 along the first direction. It should be noted that the thermal pad 23 and the buffer pad 24 are arranged on the heat dissipation area, one group of the thermal pad 23 and the buffer pad 24 is arranged in one of the sub-heat dissipation areas, and the other group of the thermal pad 23 and the buffer pad 24 is arranged in the other sub-heat dissipation area.

[0050] It should be noted that, in addition to the screen 2 and the body 1, the display device may also include other necessary components and components, such as a power cord, etc., which can be supplemented accordingly by those skilled in the art according to the specific use requirements of the display device, and will not be repeated here. The display device can be a mobile phone, a watch, a computer, a television, and a camcorder, which are not listed here one by one. In this embodiment, the display device can be a laptop computer, and the body 1 can be a keyboard set for inputting control commands.

[0051] like Fig. 9 As shown, when the display device is a laptop computer, the length B of the buffer pad 24 along the first direction is 3-4.5mm, and the length C of the buffer pad 24 along the second direction is 3-3.5mm. The length D of the thermal pad 23 along the first direction is 10-17mm, and it is designed to cover the area that the sub-air outlet can cover. The distance A between the buffer pad 24 on the left and the edge of the left mounting portion 221 along the first direction is 0-0.5mm, and the distance E between the buffer pad 24 on the right and the edge of the right mounting portion 221 along the first direction is 0-0.5mm, which can prevent the buffer pad 24 from squeezing the thermal pad 23 when deforming. The distance G between the thermal pad 23 and the edge of the mounting portion 221 along the second direction is 0-0.35mm. The purpose of setting the mounting portion 221 is to use the edge of the mounting portion 221 for alignment when attaching the thermal pad 23, and the mounting portion 221 can also be used for alignment when the support member 22 is installed to the screen 2.

[0052] The edge of the mounting portion 221 away from the extension portion 212 and the rest of the support member 22 are chamfered at the connection, so that the mounting member at this location can have a smooth transition when stamping. The distance H between the edge of the mounting portion 221 close to the extension portion 212 and the edge where the chamfer is located can be 0-0.25mm. The edge of the mounting portion 221 close to the extension portion 212 is retracted relative to the rest of the support member 22, and the retraction value S in the direction away from the edge of the extension portion 212 is 0.5mm.

[0053] It should be noted that the dimensions mentioned above are only exemplary and can be floated within the tolerance range as long as the heat dissipation and alignment requirements are met.

[0054] See also Figure 5 and Figure 7 The display module 25 has a binding area 251, and a gap M is provided between the edge of the mounting portion 221 away from the extension portion 212 and the binding area 251, and the width of the gap M is greater than the sum of the binding tolerance, the attachment tolerance, and the assembly tolerance, so as to ensure that the setting of the support member 22 does not affect the normal display of the display module 25. In this embodiment, the gap M is greater than or equal to 2.0 mm.

[0055] In addition, in order to facilitate the avoidance and alignment of the support member 22 and the display module 25, a mating portion 222 is provided between the two mounting portions 221 at the edge of the support member 22 away from the extension portion 212, and the mating portion 222 protrudes outward in the direction away from the edge of the extension portion 212. A positioning recess 2221 is also provided on the mating portion 222, and the positioning recess 2221 is concave inward in the direction close to the edge of the extension portion 212.

[0056] The display module can use an OLED display panel, a MiniLED display panel, or an LCD display panel. In this embodiment, the display module uses an OLED display panel, which is thinner and lighter than the LCD display panel and the MiniLED display panel, and can be bent. It can extend and bend with the cover plate 21 to completely cover the shaft, and display can be achieved in the bending area, so that the display panel of the display module is larger. It can be understood that when the display module uses an OLED display panel, it is thinner and lighter, and the display panel is also larger.
