[0027] In existing technologies, traditional heat dissipation methods typically involve creating openings on the sides of the display casing, commonly including openings on the back or sides. While some designs attempt to conceal the openings, this sacrifices the convenience of injection molding and the overall structural strength. However, with the development of MiniLED technology, the space available for creating heat dissipation holes in display devices is becoming increasingly limited, affecting the heat dissipation performance of display devices.

[0028] This utility model proposes a display device.

[0029] Please see Figures 1 to 4 As shown, in one embodiment of the present invention, the display device includes: a middle frame 100 and a rear shell 200. The middle frame 100 includes a first segment 110, a second segment 120, and an inclined segment 130. One end of the inclined segment 130 is connected to the first segment 110, and the other end is connected to the second segment 120. The extension direction of the inclined segment 130 forms an angle with the extension direction of the first segment 110 and the extension direction of the second segment 120, respectively. The rear shell 200 is detachably connected to the second segment 120 and forms an inner cavity 300 with the second segment 120. A heat dissipation channel 400 communicating with the inner cavity 300 is formed between the inclined segment 130 and the rear shell 200.

[0030] Understandably, the middle frame 100 is the outer perimeter frame of the display device, and the rear shell 200 is the outer shell 20 on the back of the display device. The outer shell 20 is snapped into the second segment 120 of the middle frame 100 by a snap fastener. In this embodiment, the first segment 110 and the second segment 120 of the middle frame 100 are arranged approximately perpendicularly or perpendicularly. The first segment 110 is located on the side, the second segment 120 corresponds to the rear shell 200, and the second segment 120 and the rear shell 200 form an inner cavity 300. The inclined segment 130 is located at the part where the first segment 110 and the second segment 120 are close to each other. One end of the inclined segment 130 is connected to the first segment 110, and the other end is connected to the second segment 120. Furthermore, the inclined segment 130 forms a certain angle with the first segment 110 and the second segment 120, respectively. A heat dissipation channel 400 is formed between the inclined section 130 and the edge of the rear shell 200. The heat dissipation channel 400 is connected to the inner cavity 300, allowing heat convection between the inner cavity 300 and the outside environment through the heat dissipation channel 400, thereby achieving heat dissipation. In specific implementation, after assembling the rear cover 200, the internal and external spaces of the display device are relatively independent. When a temperature difference occurs between the inside and outside, the hot gas in the inner cavity 300 exchanges with the outside air through the heat dissipation channel 400, thereby achieving the purpose of cooling. In this way, compared with traditional display devices, the design of the inclined section 130 can increase the space between the edge of the middle frame 100 and the rear shell 200 of the display device, improving the heat dissipation effect. Under the premise of display devices of the same thickness, this technical solution can improve the heat dissipation effect, and of course, it is also beneficial to the design and development of display devices.

[0031] It should be noted that the reference Figure 5 As shown, the bend of the outer frame 10 of a traditional display device is vertical, and the heat dissipation holes are opened in the outer shell 20. The small size of the heat dissipation holes affects heat dissipation, and the through-type outer shell 20 affects the aesthetics.

[0032] This utility model's technical solution involves setting an inclined section 130 in the middle frame 100, forming a heat dissipation channel 400 between the inclined section 130 and the rear shell 200. The heat dissipation channel 400 communicates with the inner cavity 300, allowing the inner cavity 300 to connect with the outside through the heat dissipation channel 400, thereby achieving heat convection and heat dissipation between the inside and outside of the display device. Compared with the prior art, under the premise of a display device of the same size, the setting of the inclined section 130 can improve the space and efficiency of heat dissipation, achieving a highly efficient heat dissipation function, ensuring stable operation of the device, while also taking into account the aesthetic pursuit of the product, making the appearance of the display device more concise and streamlined.

[0033] In one embodiment, the display device further includes a stiffener 500, which is disposed in the heat dissipation channel 400 and fixedly connected to the inclined section 130. The stiffener 500 is supported between the middle frame 100 and the rear shell 200. Specifically, the stiffener 500 is fixedly connected to the inclined section 130 of the middle frame 100. The specific connection method is selected according to the material of the stiffener 500 and the middle frame 100, such as adhesive bonding or locking connection, etc., which is not limited in this embodiment. The stiffener 500 is also connected to the rear shell 200. To facilitate the disassembly of the rear shell 200, the stiffener 500 is snap-fitted into contact with the rear shell 200. The extension direction of the stiffener 500 is consistent with the flow direction of the heat dissipation airflow to avoid affecting the airflow and thus heat dissipation.

[0034] Further, refer to Figure 3 and Figure 4 As shown, there are multiple stiffeners 500, which are spaced apart and divide the heat dissipation channel 400 into multiple sub-heat dissipation channels 410.

[0035] In the specific implementation process, multiple stiffeners 500 are set in the heat dissipation channel 400. On the one hand, the stiffeners 500 can guide the flow of heat dissipation air. On the other hand, the multiple stiffeners 500 set in the heat dissipation channel 400 can provide a certain degree of shielding for the inside of the machine body, making the inside of the machine body invisible. While ensuring a certain degree of privacy, the heat dissipation effect is guaranteed, and the overall appearance is also aesthetically pleasing.

[0036] In this embodiment, multiple stiffeners 500 are spaced apart along the extension direction of the second segment 120, dividing the heat dissipation channel 400 into multiple sub-heat dissipation channels 410, through which airflow circulates and dissipates heat. Thus, two adjacent stiffeners 500, the inclined segment 130, and the rear shell 200 form the inner wall of the sub-heat dissipation channel 410, and the sub-heat dissipation channel 410 is inclined along the line connecting the inner cavity 300 of the display device to the outside, making the inner cavity 300 invisible from the outside of the display device, thus providing a certain degree of concealment.

[0037] In one embodiment, the middle frame 100 and the rib plate 500 are integrally formed. The middle frame 100 is formed by injection molding, and in a specific implementation, the rib plate 500 and the middle frame 100 are integrally formed by injection molding. In this embodiment, the outer contour of the rib plate 500 is a triangular structure, and the side connecting the rib plate 500 and the middle frame 100 is the longest side, which facilitates demolding during the injection molding process and improves the strength of the rib plate 500.

[0038] In one embodiment, the stiffener 500 further extends to the second segment 120 and is fixedly connected to the second segment 120. In specific implementation, one end of the stiffener 500 extends to the second segment 120 of the middle frame 100, which can improve the strength and stability of the connection between the stiffener 500 and the middle frame 100, further play a good guiding role, and facilitate the injection molding and demolding of the stiffener 500.

[0039] In one embodiment, reference Figure 1 and Figure 2 As shown, a notch 510 is provided on the side of the stiffening plate 500 away from the inclined section 130, and the rear shell 200 is provided with a snap-fit ​​part 210, which snaps into the notch 510.

[0040] In the specific implementation process, the surface of the stiffening plate 500 is recessed inward to form a notch 510, which is located on the side of the stiffening plate 500 near the rear shell 200 and near the outside. The rear shell 200 is bent towards the stiffening plate 500 near the edge to form a snap-fit ​​part 210. When the rear shell 200 is installed, the snap-fit ​​part 210 facing the middle frame 100 and the inner cavity 300 is snapped into the slot, which can provide support for the edge of the middle frame 100.

[0041] In one embodiment, reference Figure 1 As shown, the display device also includes a back panel 600, which is connected to the middle frame 100. The back panel 600 has a bending portion 610, which corresponds to the inclined section 130. In specific implementation, the back panel 600 is located on the side of the middle frame 100 away from the rear shell 200. The back panel 600 cooperates with the middle frame 100, and the bending portion 610 is provided corresponding to the inclined section 130 to ensure smooth assembly of the back panel 600 and the middle frame 100.

[0042] In one embodiment, reference Figure 1 As shown, the display device also includes a frame 700, which has a receiving portion 710, and a back panel 600 has a connecting portion 620. One end of the connecting portion 620 is connected to the bending portion 610, one side of the receiving portion 710 is connected to the first segment 110, and the side of the receiving portion 710 facing away from the first segment 110 is connected to the connecting portion 620. In a specific implementation, the receiving portion 710 of the frame 700 is located between the middle frame 100 and the back panel 600, and the middle frame 100 and the back panel 600 are glued together. Specifically, one side of the receiving portion 710 is glued to the inner side of the first segment 110 of the middle frame 100, and the opposite side of the receiving portion 710 is glued to the connecting portion 620.

[0043] In one embodiment, reference Figure 1 and Figure 2As shown, in the extension direction of the second segment 120, the outer surface 520 of the stiffener 500 is closer to the interior of the display device than the outer surface of the first segment 110. In specific implementation, the outer surface 520 of the stiffener 500 is the surface facing away from the inner cavity 300, that is, the surface facing the outside, and the outer surface of the first segment 110 is the surface facing the outside. Since the outer surface 520 of the stiffener 500 is closer to the interior of the display device than the outer surface of the first segment 110, a groove is formed at the end of the first segment 110 on the outer surface 520 of the stiffener 500. Under certain conditions, such as when viewed along the extension direction of the first segment 110 towards the rear shell 200, the first segment 110 can conceal and shield the heat dissipation channel 400 and the stiffener 500, improving the overall aesthetics of the display device.

[0044] In the extending direction of the second segment 120, the outer surface 520 of the rib 500 is closer to the interior of the display device than the outer surface of the rear shell 200. In this embodiment, the outer surface of the rear shell 200 refers to the outer surface of the rear shell 200 facing one side. Thus, the rear shell 200 and the rib 500 form a groove. Under certain conditions, such as when viewed along the extending direction of the first segment 110 in a direction away from the rear shell 200, the rear shell 200 can conceal the heat dissipation channel 400 and the rib 500. In addition, referring to the above, the inwardly recessed groove formed by the surfaces of the middle frame 100 and the rear shell 200 facing each other, as well as the outer surface 520 of the rib 500, can conceal the rib 500 and the heat dissipation channel 400, improving the aesthetics of the display device.

[0045] In one embodiment, reference Figure 4 As shown, heat dissipation channels 400 are provided around the periphery of the display device. The heat dissipation channels 400 are arranged around the periphery of the display device, and air convection can be carried out between the inner cavity 300 and the outside through the heat dissipation channels 400, thereby improving the heat dissipation effect of the inner cavity 300.

[0046] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the inventive concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
