[0042] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0044] In the related art, such as Figure 1An exemplary structural diagram of a display device is shown. Exemplarily, the display device includes a display panel 1, a backplane 3, a frame 2, and a cover plate 1. One side of the backplane 3 facing the light-emitting direction of the display panel 4 is used to fix the display panel 4, and one side of the backplane 3 away from the light-emitting direction of the display panel 4 is used to fix the frame 2. The frame 2 and the cover plate 1 together form a backpack for encapsulating the system circuit. The frame 2 on the four sides is first fixed to the backplane 3 separately, and then the cover plate 1 is covered on the frame 2 and fixed. Among them, the frame 2 includes an upper frame 21, a lower frame 22, and two side frames 23. The cover plate 1 is fixed to the frame 2 by bolts. Specifically, the cover plate 1 is snap-connected to the upper frame 21, and the cover plate 1 is fixed to the lower frame 22 by bolts. The above-mentioned display device can be an OLED display device such as a monitor or a TV exemplarily, and the display device is an extra-large size (for example, 95 inches). When the display device is placed, it is placed vertically (along the a direction in the figure). Since the display device tends to be large-sized, and with the aging of the product or the vibration of the speaker, the supporting ability of the lower frame 22 weakens. Under the action of the gravity of the cover plate 1, the gap G between the cover plate 1 and the upper frame 21 will become larger, resulting in the internal circuit of the frame 2 being easily affected by moisture and other problems, reducing the service life of the display device.

[0045] Figure 2 The structural diagram of the display device according to the embodiment of the present invention is shown.

[0046] As Figure 2 shown, the present invention provides a display device, including:

[0047] A display panel;

[0048] A backplane 3, one side of the backplane 3 facing the light-emitting direction of the display panel is used to fix the display panel, and an installation position 301 is provided on one side of the backplane 3 away from the light-emitting direction of the display panel;

[0049] A frame 2, arranged on one side of the backplane 3 away from the display panel, the installation position 301 defines the installation position of the frame 2, and a lapping part 20 is provided on one side of the frame 2 away from the backplane 3, and the lapping part 20 and the side wall of the frame 2 form an installation space 201;

[0050] A cover plate 1, fixedly arranged in the installation space 201 and lapping with the lapping part 20;

[0051] Among them, the lower frame 22 of the frame 2 is connected to the side frames on both sides of the lower frame 22 through a reinforcing frame 25, so that the side frames decompose the gravity of the lower frame 22 through the reinforcing frame 25.

[0052] Specifically, the display panel is an OLED display panel and has a rectangular plate-like structure, so as toFigure 2 Taking the middle orientation as an example, the long side of the rectangle of the display panel extends horizontally, and the rectangular end face of the display panel extends vertically. When assembling the display device, the display panel is mounted on one side of the backplane 3, the non-light-emitting side of the display panel is connected to one side of the backplane 3, and an installation position 301 for mounting the frame 2 is provided on the side of the backplane 3 away from the light-emitting direction of the display panel. The installation position 301 defines the installation position of the frame 2, so that the frame 2 is installed in the installation position 301, so that the circuit components 302 located in the frame 2 can be better connected to the display panel. A lapping portion 20 is provided on the side of the frame 2 away from the backplane 3, and the lapping portion 20 is arranged around the inner wall of the frame 2. In this way, an installation space 201 is formed between the lapping portion 20 and the side wall of the frame 2, and the cover plate 1 is fixedly arranged in the installation space 201, and the cover plate 1 is lapped on the lapping portion 20. Among them, the frame 2 is rectangular and includes four frames. The lapping portion 20 can be integrally formed with the side walls of the respective frames of the frame 2, or can be a lapping strip fixed on the side walls of the respective frames. The lower frame 22 of the frame 2 is connected to the side frames located on both sides of the lower frame 22 through a reinforcing frame 25. In this way, the side frames decompose the gravity of the cover plate 1 on the lower frame 22 through the reinforcing frame 25. Since the display device is placed vertically, connecting the lower frame 22 and the side frames through the reinforcing frame 25 can reduce the deformation of the lower frame 22 under the gravity of the display panel, thereby reducing the gap between the lower frame 22 and the display panel and improving the service life of the display device.

[0055] Figure 5 Shows an embodiment of the present invention Figure 4 Schematic cross-sectional structure diagram along the F1 direction in the middle.

[0056] Figure 6 Shows an embodiment of the present invention Figure 4 Schematic cross-sectional structure diagram along the U2 direction in the middle.

[0057] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a first stud 31 for installing the upper frame 21 of the frame body 2 and a first mounting hole 30 for installing the lower frame 22 of the frame body 2 are provided in the mounting position 301. A through hole matching the first stud 31 is provided on the upper frame 21 of the frame body 2. The first stud 31 and the through hole are fixedly connected by screws. A second mounting hole 2201 matching the first mounting hole 30 is provided on the lower frame 22 of the frame body 2. The first mounting hole 30 and the second mounting hole 2201 are fixedly connected by screws.

[0058] In this embodiment, as Figure 3 and Figure 4 shown, the frame body 2 includes an upper frame 21, a lower frame 22, a left frame 23 and a right frame 24. As Figure 5 shown, the fixing method of the upper frame 21 and the back plate 3 is as follows: at a position near the upper part in the mounting position 301 on the back plate 3 for installing the upper frame 21, a first stud 31 is provided. A plurality of first studs 31 can be arranged in an array. A through hole matching the first stud 31 is provided on the upper frame 21. The first stud 31 is located in the through hole. A screw hole is provided at the inner end of the through hole, and the screw hole communicates with the through hole. In this way, when the first stud 31 is inserted into the through hole or fixed to the upper frame 21 by screws (exemplarily, such as Figure 5 the third screw 311 in Figure 6 shown, the fixing method of the lower frame 22 and the back plate 3 is as follows: at a position near the lower part in the mounting position 301 on the back plate 3 for installing the lower frame 22, a first mounting hole 30 is provided. A second mounting hole 2201 matching the first mounting hole 30 is provided on the lower frame 22. The first mounting hole 30 and the second mounting hole 2201 are fixedly connected by screws. In this way, the lower frame 22 is fixedly connected to the back plate 3 by screws. When the upper frame 21 and the lower frame 22 are fixed in the mounting position 301 of the back plate 3 by screws, the entire frame body 2 is fixed to the back plate 3.

[0059] In this embodiment, as Figure 6 shown, a window 222 is formed on one side of the lower frame 22 facing the back plate 3. The orthographic projection of the window 222 does not overlap with the orthographic projection of the back plate 3. A glass 223 is installed at the window 222 of the lower frame 22.

[0060] Exemplarily, a circuit component 302 and various indicator lights are installed inside the frame body 2. By providing the window 222 on the lower frame 22 and the orthographic projection of the window 222 not overlapping with the orthographic projection of the back plate 3, as Figure 6It can be seen that the window 222 is located below the back plate 3. In this way, the display of each indicator light can be carried out through the window 222, which is convenient for users to view the operation status of the display device. Installing the glass 223 at the window 222 can play a role in beautification, and at the same time can prevent dust from entering the interior of the window 222 and affecting the operation of the circuit component 302.

[0061] In this embodiment, as Figure 6 shown, one side of the lower frame 22 facing the upper frame 21 extends towards the upper frame 21 to form a mounting edge 220. The orthographic projection of the mounting edge 220 overlaps with the orthographic projection of the back plate 3, and the second mounting hole 2201 is provided on the mounting edge 220.

[0062] Exemplarily, one side of the lower frame 22 facing the upper frame 21 extends upwards to form a mounting edge 220. The mounting edge 220 and the lower frame 22 form a Z shape. The second mounting hole 2201 is provided on the mounting edge 220. The mounting edge 220 is fixed to the back plate 3 by screws. At this time, the end face of the lower frame 22 relative to the back plate 3 is in a sunken state. In this way, the window 222 of the lower frame 22 is located below and sunken with respect to the back plate 3. In this way, the circuit component 302 located in the housing 2 does not affect the display content of the display panel located on the back plate 3, making the display brightness of the display panel more stable.

[0063] Figure 7 shows a cross-sectional structure schematic diagram of the embodiment of the present invention Figure 4 along the U1 direction.

[0064] Figure 8 shows a cross-sectional structure schematic diagram of the embodiment of the present invention Figure 4 along the F3 direction.

[0065] In some embodiments, as Figure 7 and Figure 8 shown, one side of the cover plate 1 facing the housing 2 is provided with at least one clamping member 102 that is clamped with the upper frame 21 and at least one mounting member 110 that is connected to the lower frame 22. The overlapping portion 20 forms a clamping portion 210 on the upper frame 21. The clamping portion 210 is in clamping cooperation with the at least one clamping member 102. The overlapping portion 20 forms a first retaining edge 221 on the lower frame 22. The mounting member 110 passes through the first retaining edge 221 and is fixedly connected to the lower frame 22.

[0066] Exemplarily, a plurality of clamping members 102 are arranged in an array on the cover plate 1. The clamping members 102 are fixed to the cover plate 1 by screws. The clamping members 102 are located above the cover plate 1. An insertion hole is formed between the clamping members 102 and the cover plate 1. The overlapping portion 20 (such as Figure 7A protrusion with an inclined surface) forms a clamping portion 210 on the upper frame 21. The clamping portion 210 is clamped with the arrayed clamping members 102, that is, the clamping portion 210 is inserted into the jacks between the respective clamping members 102 and the cover plate 1; the installation of the cover plate 1 and the upper frame 21 is completed. A plurality of mounting members 110 are arrayed below the cover plate 1. The plurality of mounting members 110 can be fixed to the cover plate 1 by screws or can be adhered to the cover plate 1 by adhesive, which is not specifically limited in the present utility model. As Figure 6 shown, the overlapping portion 20 forms a first retaining edge 221 on the lower frame 22, and the cover plate 1 overlaps on the first retaining edge 221, as Figure 8 shown, through holes corresponding to the plurality of mounting members 110 are provided on the first retaining edge 221. The mounting members 110 are arranged through the through holes, and after the mounting members 110 pass through the through holes, they are fixedly connected to the lower frame 22 by screws, and the installation of the cover plate 1 and the lower frame 22 is completed. For the specific installation process, first, the upper part of the cover plate 1 is obliquely inserted into the clamping portion 210, then the lower part of the cover plate 1 overlaps on the first retaining edge 221, and the mounting members 110 on the cover plate 1 pass through the first retaining edge 221 and are screwed to the lower frame 22, that is, the screws are installed below the lower frame 22, which can hide the screws and ensure the beauty of the display device. Among them, the first retaining edge 221 can also block the gap between the cover plate 1 and the upper frame 21, and can hide the circuit components 302 in the frame body 2.

[0067] In some embodiments, as Figure 5 and Figure 7 shown, a slope is provided on one side of the clamping portion 210 facing the cover plate 1, an inclined portion 100 matching the slope is provided on the side wall of the cover plate 1, and a buffer strip 101 is provided on the inclined portion 100. The buffer strip 101 is arranged between the slope and the inclined portion 100.

[0068] Exemplarily, the end surface of the clamping portion 210 is inclined, that is, it has a slope. The side wall of the cover plate 1 is provided with an inclined portion 100 matching the slope. When the cover plate 1 and the upper frame 21 are installed, due to the existence of the inclined surface, the installation of the cover plate 1 can be more smooth. A buffer strip 101 is provided on the inclined portion 100. In this way, the buffer strip 101 is arranged between the upper frame 21 and the cover plate 1, which can prevent the gap between the cover plate 1 and the frame body 2 from increasing when the device vibrates and reduce the vibration amplitude.

[0069] In some embodiments, as Figure 5 shown, a first operation hole 211 is provided on the clamping portion 210, and the orthographic projection of the first operation hole 211 on the back plate 3 overlaps with the orthographic projection of the first stud 31 on the back plate 3.

[0070] Exemplarily, as Figure 5As shown, the first operation hole 211 corresponds to the first stud 31, and the diameter of the first operation hole 211 is greater than the diameter of the through hole corresponding to the first stud 31. In this way, it is convenient to insert an installation tool into the first operation hole 211 to fix the first stud 31 and the upper frame 21.

[0071] In some embodiments, such as Figure 5 As shown, the width of the clamping portion 210 at the first operation hole 211 is greater than the distance between the cover plate 1 and the upper frame 21.

[0072] Exemplarily, the distance between the cover plate 1 and the upper frame 21 is G, and the width of the clamping portion 210 at the first operation hole 211 is a, where a > G. In this way, the width of the clamping portion 210 is greater than the distance between the cover plate 1 and the upper frame 21, which can hide the circuit components 302 inside the frame 2 and prevent a large amount of dust from entering the frame 2 through the first operation hole 211.

[0073] Figure 9 Shows a schematic cross-sectional structure diagram of an embodiment of the present invention Figure 4 along the U4 or F2 direction.

[0074] In some embodiments, such as Figure 9 As shown, the mounting position 301 is provided with second studs 32 for mounting the side frames on both sides of the frame 2, and the side frames are provided with first screw holes 245 fixedly connected to the second studs 32.

[0075] Exemplarily, the frame 2 in the present invention includes a left frame 23 and a right frame 24. The mounting position 301 of the back plate 3 is provided with second studs 32 for mounting the left frame 23 and the right frame 24. One side of the side frame facing the back plate 3 is provided with first screw holes 245 corresponding to the second studs 32. The first screw holes 245 and the second studs 32 are fixedly connected by screws (such as Figure 9 the fifth screw 321). In this way, the left frame 23 and the right frame 24 are fixed to the back plate 3 by screws.

[0076] In this embodiment, the side frame is internally provided with a cavity 243. The first screw hole 245 is provided on the side wall of the side frame facing the back plate 3. The side frame is provided with a second operation hole 244 on the side away from the back plate 3, and the orthographic projection of the second operation hole 244 overlaps with the orthographic projection of the first screw hole 245.

[0077] Furthermore, one side of the side frame facing the other side frame is provided with an opening 2431, and the direction of the opening 2431 is perpendicular to the direction of the first screw hole 245.

[0078] Exemplarily, a cavity 243 is provided inside the left frame 23 and the right frame 24. The first screw hole 245 is disposed at the bottom of the cavity 243 within the cavity 243. A second operation hole 244 is provided at the top of the cavity 243. The second operation hole 244 is larger than the first screw hole 245. An operating tool needs to be inserted into the second operation hole 244 to tighten the screw in the first screw hole 245, thereby fixing the side frame and the back plate 3. Since an opening 2431 is provided on the side wall of the cavity 243, the connection and fixing process between the side frame and the back plate 3 can be observed through the opening 2431 to ensure that the screw is accurately fixed to the second stud 32.

[0079] Figure 10 shows a schematic cross-sectional view of an embodiment of the present invention Figure 4 along the U3 direction.

[0080] In some embodiments, as Figure 9 and Figure 10 shown, the overlapping portion 20 forms a second retaining edge 240 on the side of the side frame away from the back plate 3. The second operation hole 244 is provided on the second retaining edge 240. At least one limiting member 105 is provided on the side wall of the cover plate 1 that overlaps with the second retaining edge 240. The limiting member 105 is inserted into the second operation hole 244.

[0081] The limiting member 105 has a structure that is wider at the top and narrower at the bottom.
