[0075] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0076] In addition, the present disclosure may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present disclosure provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0077] The present disclosure is described below with reference to specific embodiments and in conjunction with the accompanying drawings:

[0078] During the use and transportation of the display product, the back cover 300 is the part that is often pressed and touched. The large flat area of ​​the back cover 300 is prone to sinking when pressed, resulting in a reduction in the distance between the back cover 300 and the internal circuit components of the display product, which can easily damage the internal circuit components of the display product and cause the risk of electric shock.

[0079] See also Figure 1 As shown in FIG, a schematic diagram of the three-dimensional structure of the rear shell 300 in the display device in the related art is shown. Figure 1 As shown, the display device can improve the structural strength of the rear shell 300 by adding top ribs inside the rear shell 300, or adding support columns 10 inside the rear shell 300 to support the rear shell 300 between the rear shell 300 and the back plate 200 when the rear shell 300 is pressed, thereby, to a certain extent, preventing the large flat area of ​​the rear shell 300 from sinking when pressed. However, the solution of adding top ribs and / or support columns 10 inside the rear shell 300 increases the difficulty of processing the mold of the rear shell 300, resulting in an increase in the cost of the mold of the rear shell 300 and an increase in the material cost of the rear shell 300. At the same time, the top ribs and / or support columns 10 provided on the rear shell 300 are structures that protrude relative to the large flat area of ​​the rear shell 300. During the packaging and transportation process of the rear shell 300 material, the top ribs and / or support columns 10 on the rear shell 300 are easily deformed or broken, resulting in loss of the rear shell 300 material, which in turn leads to an increase in the cost of the rear shell.

[0080] Furthermore, in the related art, the key assembly 400 in the display device supports the key body 410 via a key bracket 420, which is secured to the display device via key bracket fixing holes 4215 at its ends. Because the key body 410 is frequently pressed during use of the display device, when the key bracket 420 is secured only via the key bracket fixing holes 4215 at its ends, the central region of the key bracket 420 is suspended in the air. Consequently, if the key body 410 is subjected to a large amount of pressure or is pressed frequently, the central region of the key bracket 420 may deform after being pressed with such a large external force or frequently, thereby affecting the tactile feel of the key body 410 and the user's experience.

[0081] In order to solve the technical problems that the rear shell 300 of the display device is easily depressed by being pressed and the key bracket 420 is easily deformed, the embodiment of the present disclosure proposes a display device, such as Figures 9 to 21 、 Figures 34 to 39 As shown, the display device includes a display module 100, a back panel 200, a rear shell 300, a key assembly 400, and a support bracket 500. Among them, the back panel 200 is arranged on the backlight side of the display module 100; the rear shell 300 is buckled on the back panel 200, and the rear shell 300 includes a back rear shell 310 and a side rear shell 320 that are connected to each other. The back rear shell 310 is located on the side of the back panel 200 away from the display module 100, and the side rear shell 320 is surrounded by the back panel 200. The side rear shell 320 includes a first side rear shell 321, and the first side rear shell 321 is provided with a key through hole 322; the key assembly 400 includes a key body 410 and a key bracket 420 supporting the key body 410. The key body 410 It is arranged at the button through hole 322; the support bracket 500 is located between the back panel 200 and the back shell 310, and the support bracket 500 includes a first support plate 510, a second support plate 520 and a third support plate 530. The first support plate 510 is fixed to the side of the back panel 200 close to the back shell 310, the second support plate 520 is fixed to the side of the back shell 310 close to the back panel 200, the third support plate 530 connects the first support plate 510 and the second support plate 520, and the third support plate 530 is supported on the side of the button bracket 420 away from the first side shell 321.

[0082] The display device provided by the embodiment of the present disclosure is as follows: Figures 9 to 21As shown, the support bracket 500 in the display device is located between the back plate 200 and the back shell 310, the first support plate 510 is fixed on the back plate 200, the second support plate 520 is fixed on the back shell 300, and the third support plate 530 is connected between the first support plate 510 and the second support plate 520. Therefore, the support bracket 500 can be supported between the back plate 200 and the back shell 310, and can limit the distance between the back plate 200 and the back shell 310 in a direction perpendicular to the back plate 200, that is, in the first direction F1 shown in the figure. When the back shell 310 is pressed, the support bracket 500 can provide support for the back shell 310, thereby dispersing the pressure on the back shell 310. The force exerted by the back shell 310 can, to a certain extent, avoid the reduction in the distance between the back shell 310 and the back plate 200 caused by the deformation of the back shell 310, thereby preventing the back shell 310 from sinking and crushing the components inside the display device, and can also avoid the risk of electric shock to a certain extent; the support bracket 500 can also replace the top ribs and / or support columns 10 and other structures preset on the back shell 310, thereby reducing the processing difficulty of the back shell 300 mold, reducing the manufacturing cost of the back shell 300 mold, and also reducing the loss and cost of the back shell 300 material; the support bracket 500 is arranged between the back plate 200 and the back shell 300 of the display device, and the setting position and setting quantity in the display device are more flexible. At the same time, the third support plate 530 is supported on the side of the button bracket 420 away from the first side rear shell 321, thereby providing a certain support for the button bracket, which can improve the deformation resistance of the button bracket 420, thereby avoiding the button bracket 420 from being deformed by force to a certain extent and affecting the pressing experience of the button body 410, that is, reducing the deformation of the button bracket 420 due to a large external force or a more frequent pressing, thereby ensuring the touch feel of the button body 410 when pressed, and optimizing the user experience.

[0083] In some embodiments of the present disclosure, a display device may include multiple support brackets 500. By distributing the multiple support brackets 500 between the back panel 200 and the rear housing 300 of the display device, the support brackets 500 can be relatively evenly supported between the back panel 200 and the rear housing 310, thereby ensuring a relatively stable spacing between the back panel 200 and the rear housing 310. Those skilled in the art can adjust the number and distribution of the support brackets 500 in the display device according to the size of the display device, and detailed description thereof will not be given here.

Optionally, the first support plate 510 is fixed to the back plate 200 using tapping as a connector. For example, an M3 tapping thread can be used, and the diameter of the M3 tapping thread is 2.5 mm. Optionally, the inner diameter of the first support plate fixing hole 511 is larger than the diameter of the M3 tapping thread; for example, the inner diameter of the first support plate fixing hole 511 can be 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, or 5.0 mm. Optionally, the inner diameter of the first support plate fixing hole 511 is greater than the diameter of the M3 tapping thread by at least 0.5 mm, that is, the inner diameter of the first support plate fixing hole 511 is greater than or equal to 3.5 mm; for example, the inner diameter of the first support plate fixing hole 511 can be 3.5 mm, 4.0 mm, or 4.5 mm. Similarly, the second support plate 520 and the second support plate fixing hole 521 may be arranged in the same manner as the first support plate 510 and the first support plate fixing hole 511 , and will not be described in detail herein.

[0087] In some embodiments of the present disclosure, Figures 9 to 21 As shown, the first support plate 510 is provided with at least two first support plate fixing holes 511. In the length direction of the first support plate 510, that is, Figures 9 to 21 In the second direction F2 shown, the distance between adjacent first support plate fixing holes 511 can be 150mm to 250mm. By setting the distance between adjacent first support plate fixing holes 511 to 150mm to 250mm, it is possible to avoid the first support plate fixing holes 511 being arranged too loosely and failing to achieve the connection and locking effect with the back plate 200, and to avoid the first support plate fixing holes 511 being arranged too densely, resulting in overlapping fastening effects and an excessive number of required connectors, which would increase costs and assembly workload. For example, Figures 9 to 21As shown, in the second direction F2, two first support plate fixing holes 511 are provided on the first support plate 510, and the distance between adjacent first support plate fixing holes 511 is 183 mm.

[0088] In some embodiments of the present disclosure, Figures 9 to 21 As shown, the second support plate 520 is provided with at least two second support plate fixing holes 521. In the length direction of the second support plate 520, that is, Figures 9 to 21 In the second direction F2 shown, the distance between adjacent second support plate fixing holes 521 can be 100mm to 200mm. By making the distance between adjacent second support plate fixing holes 521 100mm to 200mm, it is possible to avoid the second support plate fixing holes 521 being arranged too loosely and failing to achieve the connection and locking effect with the rear housing 300, and to avoid the second support plate fixing holes 521 being arranged too densely, resulting in overlapping fastening effects and an excessive number of required connectors, which will increase costs and assembly workload. For example, Figures 9 to 21 As shown, in the second direction F2, two second support plate fixing holes 521 are provided on the second support plate 520, and the distance between adjacent first support plate fixing holes 511 is 140 mm.

[0089] In some embodiments of the present disclosure, Figures 9 to 21 As shown, in the width direction of the first support plate 510, that is, Figures 9 to 21 In the third direction F3 shown, if the width of the first support plate 510 is too small, the purpose of connecting and locking the first support plate 510 to the back plate 200 cannot be achieved through the connecting parts; if the width of the first support plate 510 is too large, on the one hand, it is easy to interfere with the devices on the back plate 200, and on the other hand, it is easy to cause waste of materials, resulting in increased costs. Optionally, by making the width of the first support plate 510 in the third direction F3 20mm ~ 40mm, it is possible to conveniently set the first support plate fixing hole 511 on the first support plate 510, and realize the connection and locking of the first support plate 510 and the back plate 200 through the first support plate fixing hole 511, and avoid the waste of materials caused by the excessive width of the first support plate 510 in the third direction F3. Similarly, in the width direction of the second support plate 520, that is, Figures 9 to 21If the width of the second support plate 520 in the third direction F3 is too small, the second support plate 520 cannot be connected and locked to the back shell 310 via the connector. If the width of the second support plate 520 is too large, it is easy to waste materials and increase costs. Optionally, by setting the width of the second support plate 520 in the third direction F3 to 20 mm to 40 mm, it is convenient to set the second support plate fixing hole 521 on the second support plate 520 and connect and lock the second support plate 520 to the back shell 300 through the second support plate fixing hole 521, while also avoiding the waste of materials caused by the excessive width of the second support plate 520 in the third direction F3. For example, in some embodiments, the width of the first support plate 510 can be 20 mm, 26 mm, 30 mm, 35 mm, or 40 mm, etc.; the width of the second support plate 520 can be 20 mm, 26 mm, 30 mm, 35 mm, or 40 mm, etc.

[0090] In some embodiments of the present disclosure, Figures 9 to 21 As shown, in the second direction F2, the length of the support bracket 500 can be adaptively adjusted according to the side length of the display device and the number of support brackets 500 provided. In other words, the length of the first support plate 510, the length of the second support plate 520, and the length of the third support plate 530 in the support bracket 500 can be adaptively adjusted according to the side length of the display device and the number of support brackets 500 provided, and the lengths of the first support plate 510, the length of the second support plate 520, and the lengths of the third support plate 530 can be the same or different. When the side length of the display device is long, the length of the support bracket 500 and / or the number of support brackets 500 provided can be appropriately increased; when the side length of the display device is short, the length of the support bracket 500 and / or the number of support brackets 500 provided can be appropriately shortened.

[0091] As an optional implementation, Figure 15 Figure 19 、 Figures 34 to 39As shown, the key bracket 420 includes a first support frame 421, and the key assembly 400 also includes a key circuit board 430, which is supported on the first support frame 421. The key body 410 is located on the side of the key circuit board 430 close to the first side rear shell 321. The key body 410 can be movably arranged on the first support frame 421 to make the key body 410 abut and separate from the key circuit board 430, wherein the orthographic projection of the first support frame 421 on the first side rear shell 321 at least partially overlaps with the orthographic projection of the third support plate 530 on the first side rear shell 321; the third support plate 530 is provided with a key avoidance opening 531, and the orthographic projection of the third support plate on the first side rear shell 321 does not overlap with the orthographic projection of the key circuit board 430 on the first side rear shell 321.

[0092] In some embodiments of the present disclosure, Figure 15 Figure 19 、 Figures 34 to 39 As shown, the key assembly 400 further includes a key circuit board 430, which is supported on a first support frame 421. Specifically, the key circuit board 430 is supported by the first support frame 421. A key body 410 is located on a side of the key circuit board 430 near the first side rear shell 321. The key body 410 is movably disposed on the first support frame 421 to allow the key body 410 to abut and separate from the key circuit board 430. This allows the key body 410 to abut against the key circuit board 430 when pressed, and to separate from the key circuit board 430 when released, thereby achieving the basic function of the key assembly 400. Furthermore, the key bracket 420 includes a first support frame 421. The orthographic projection of the first support frame 421 on the side rear shell 320 at least partially overlaps with the orthographic projection of the third support plate 530 on the side rear shell 320, thereby supporting the first support frame via the third support plate 530. The third support plate 530 is provided with a key avoidance opening 531, through which the orthographic projection of the third support plate 530 on the first side rear shell 321 and the orthographic projection of the key circuit board 430 on the first side rear shell 321 do not overlap, thereby preventing the side of the key circuit board 430 adjacent to the third support plate 530 from abutting against the third support plate 530, thereby preventing various components on the side of the key circuit board 430 adjacent to the third support plate 530 from interfering with the third support plate 530.

[0093] In some embodiments of the present disclosure, Figure 15 Figure 19As shown, optionally, the key bracket 420 also includes a second support bracket 422 connected to the first support bracket 421. When the orthographic projection of the first support bracket 421 on the side rear shell 320 at least partially overlaps with the orthographic projection of the third support plate 530 on the side rear shell 320, the second support bracket 422 can be supported on the third support plate 530, thereby achieving the purpose of supporting the key bracket 420 by the third support plate 530.

[0094] In some embodiments of the present disclosure, Figure 15 Figure 19 、 Figures 34 to 39 As shown, the orthographic projection of the first support frame 421 on the first side rear shell 321 and the orthographic projection of the third support plate 530 on the first side rear shell 321 at least partially overlap, and a key avoidance opening 531 can be provided on the third support plate 530 so that the orthographic projection of the third support plate 530 on the first side rear shell 321 and the orthographic projection of the key circuit board 430 on the first side rear shell 321 do not overlap, and a key support area 533 can be formed around the key avoidance opening 531, and the key support area 530 is the overlapping area of ​​the orthographic projection of the first support frame 421 on the first side rear shell 321 and the orthographic projection of the third support plate 530 on the first side rear shell 321, and the key support area 533 can be supported on the side of the key bracket 420 away from the first side rear shell 321, that is, the key support area 533 3 can be supported on the back side of the key bracket 420, so that the key bracket 420 can be supported on all sides by the key support area 533. At the same time, by arranging the first support plate 510 and the second support plate 520 on both sides of the third support plate 530, the first support plate 510 and the second support plate 520 can improve the structural strength of the third support plate 530, thereby improving the structural strength of the key support area 533, thereby improving the support effect on the key bracket 420, and to a certain extent, avoiding the deformation of the key bracket 420 and affecting the pressing experience of the key body 410, that is, reducing the deformation of the middle area of ​​the key bracket 420 due to a large external force or a high frequency of pressing, thereby ensuring the touch feel of the key body 410 when pressed, and optimizing the user experience.

[0095] In some embodiments of the present disclosure, Figure 9 Figure 21 As shown, the support bracket 500 can be used to support the rear shell 300 to prevent the rear shell 300 from sinking due to force, and can also be used to support the key bracket 420 to prevent the middle area of ​​the key bracket 420 from being deformed due to force, so that the support bracket 500 can achieve multiple uses, improve the use effect of the structural component, reduce the number of structural components set in the display device, and thus further reduce the material cost and labor cost of the display device.

[0096] In some embodiments of the present disclosure, Figures 9 to 21 As shown, a key avoidance opening 531 and a key support area 533 are provided on the third support plate 530, so that when the key support area 533 supports the key bracket 420, in the length direction of the first support plate 510, that is, Figures 9 to 21 In the second direction F2 shown, the respective lengths of the first support plate 510, the second support plate 520 and the third support plate 530 in the support bracket 500 and the size of the key avoidance opening 531 can be adaptively adjusted according to the size of the key assembly 400. It is necessary to make the length of the key avoidance opening 531 greater than or equal to the length of the key 410 distributed on the key bracket 420, and at the same time, it is necessary to make the length of the third support plate 530 greater than the length of the key avoidance opening 531.

[0097] In some embodiments of the present disclosure, Figures 9 to 21 As shown, at least two third support plate fixing holes 534 can be provided on the third support plate 530, and the button bracket 420 can be fixed on the third support plate 530 through the connecting piece and the third support plate fixing hole 534 to achieve the connection and locking between the button bracket 420 and the third support plate 530.

[0098] In some embodiments of the present disclosure, Figures 9 to 21 As shown, in the length direction of the third support plate 530, that is, Figures 9 to 21 In the second direction F2 shown, at least one third support plate fixing hole 534 can be respectively provided at opposite ends of the key avoidance opening 531, so as to fix the key bracket 420 to the third support plate 530 through the third support plate fixing hole 534. The distance between the opposing third support plate fixing holes 534 can be adaptively adjusted according to the dimensions of the key bracket 420 and the key circuit board 430; and the diameter of the third support plate fixing hole 534 can be adaptively adjusted according to the dimensions of the selected connector.

[0099] In some embodiments of the present disclosure, Figures 9 to 21 As shown, in the length direction of the third support plate 530, that is, Figures 9 to 21 In the second direction F2 shown, the length of the third support plate 530 and the size of the key avoidance opening 531 can be adaptively adjusted according to the size of the key assembly 400. It is necessary to make the length of the key avoidance opening 531 larger than the range of the key body 410 distributed on the key bracket 420. At the same time, it is necessary to make the length of the third support plate 530 larger than the length of the key avoidance opening 531. For example, in Figures 9 to 19 In the illustrated embodiment, the length of the third support plate 530 may be 288 mm.

[0100] In some embodiments of the present disclosure, Figures 9 to 21 As shown, in the length direction of the third support plate 530, that is, Figures 9 to 21In the second direction F2 shown, the distance between the third support plate fixing holes 534 relatively arranged at both ends of the key avoidance opening 531 may be 196 mm.

[0101] In some embodiments of the present disclosure, Figures 9 to 21 As shown, the key bracket 420 can be fixed to the third support plate 530 using tapping as a connector. For example, the key bracket 420 can be fixed to the third support plate 530 using tapping M3, where the diameter of the tapping M3 is 2.5 mm. Optionally, the inner diameter of the third support plate fixing hole 534 is larger than the diameter of the tapping M3; for example, the inner diameter of the third support plate fixing hole 534 can be 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, or 5.0 mm. Optionally, the inner diameter of the third support plate fixing hole 534133 is larger than the diameter of the tapping M3 by at least 0.5 mm, i.e., the inner diameter of the third support plate fixing hole 534 is greater than or equal to 3.5 mm; for example, the inner diameter of the third support plate fixing hole 534 can be 3.5 mm, 4.0 mm, or 4.5 mm.

[0102] As an optional implementation, Figures 9 to 21 As shown, a channel avoidance opening 535 is provided on the third support plate 530, and the channel avoidance opening 535 is used to avoid any one or more of the power jack 940, audio jack, video jack, sound receiving hole, sound releasing hole and heat dissipation hole of the display device; accordingly, the first side rear shell 321 is provided with a channel through hole 323 corresponding to the channel avoidance opening 535.

[0103] In the display device, the side where the button 410 is provided is often also provided with a power jack 940, an audio jack, a video jack, a sound receiving hole, a sound emitting hole, a heat dissipation hole and other channel structures.

[0104] In some embodiments of the present disclosure, Figures 9 to 21 As shown, a channel avoidance opening 535 is provided on the third support plate 530. Channel avoidance opening 535 allows for channel structures such as the power jack 940, audio jack, video jack, sound receiving hole, sound emitting hole, and heat dissipation hole to be avoided. Furthermore, the third support plate 530 can also support the perimeter of these channel structures, thereby ensuring the structural strength of these channel structures during use.

[0105] In some embodiments of the present disclosure, a channel avoidance opening 535 is provided on the third support plate 530. Channel structures such as the power jack 940, audio jack, video jack, sound receiving hole, sound emitting hole, and heat dissipation hole can be avoided through the channel avoidance opening 535. The size of the channel avoidance opening 535 can match the size of the corresponding power jack 940, audio jack, video jack, sound receiving hole, sound emitting hole, and heat dissipation hole.

[0106] In some embodiments of the present disclosure, Figures 9 to 21 As shown, when the third support plate 530 is provided with a key avoidance opening 531 and a key support area 533 located around the key avoidance opening 531, the key bracket 420 can be supported by the key support area 533, and a channel avoidance opening 535 is provided for avoiding channel structures such as the power jack 940, audio jack, video jack, sound receiving hole, sound releasing hole and heat dissipation hole, the length of each support plate in the support bracket 500, the size of the key avoidance opening 531 and the size of the channel avoidance opening 535 can be adaptively adjusted according to the distribution length and position of the key assembly 400, power jack 940, audio jack, video jack, sound receiving hole, sound releasing hole and heat dissipation hole in the display device, which will not be repeated here. For example, the third support plate 530 is provided with a button avoidance opening 531 and a channel avoidance opening 535, and the channel avoidance opening 535 is used to avoid the power socket 940. Then, in the second direction F2, the length of at least the third support plate 530 in the support bracket 500 needs to be greater than the length of the button assembly 400 and the length of the socket.

[0107] In some embodiments of the present disclosure, Figures 9 to 21 As shown, when the channel avoidance opening 535 is used to avoid any one or more of the power jack 940, audio jack and video jack, a fourth support plate fixing hole 536 is provided on the third support plate 530, and the fourth support plate fixing hole 536 is used to connect with the corresponding base of the power jack 940, audio jack and video jack.

[0108] In the display device, corresponding bases are provided inside the sides where the power jack 940, the audio jack, the video jack, the sound receiving hole, the sound emitting hole and the heat dissipation hole are provided.

[0109] In some embodiments of the present disclosure, Figures 9 to 21As shown, a fourth support plate fixing hole 536 is provided on the third support plate 530, through which the corresponding bases of the power jack 940, audio jack, video jack, sound receiving hole, sound releasing hole and heat dissipation hole can be fixed on the third support plate 530. On the one hand, it can ensure that the power jack 940, audio jack and video jack are stable relative to the third support plate 530 and the display device during the plugging and unplugging process, avoiding shaking relative to the third support plate 530 and the display device; on the other hand, it can ensure that the corresponding bases of the sound receiving hole, sound releasing hole and heat dissipation hole are fixed on the third support plate 530, avoiding defects such as shaking and abnormal noise during use. Among them, in the second direction F2, a plurality of fourth support plate fixing holes 536 can be provided on the third support plate 530, and the fourth support plate fixing holes 536 can be relatively arranged on the opposite sides of the power jack 940, audio jack, video jack, sound receiving hole, sound releasing hole and heat dissipation hole. The distance between the relatively arranged fourth support plate fixing holes 536 can be adaptively adjusted according to the corresponding base sizes of the power jack 940, audio jack, video jack, sound receiving hole, sound releasing hole and heat dissipation hole; the aperture of the third support plate fixing hole 534 can be adaptively adjusted according to the size of the selected connector.

[0110] In some embodiments of the present disclosure, Figures 9 to 21 As shown, in the second direction F2, the distance between the fourth support plate fixing holes 536 may be 40 mm.

[0111] In some embodiments of the present disclosure, the corresponding bases of the power jack 940, audio jack, video jack, sound receiving hole, sound emitting hole, and heat dissipation hole are optionally fixed to the third support plate 530 via M3 tapping. Optionally, the inner diameter of the fourth support plate fixing hole 536 is larger than the diameter of the M3 tapping. For example, the inner diameter of the fourth support plate fixing hole 536 can be 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, or 5.0 mm. Optionally, the inner diameter of the fourth support plate fixing hole 536 is greater than the diameter of the M3 tapping. That is, the inner diameter of the fourth support plate fixing hole 536 is greater than or equal to 3.5 mm. For example, the inner diameter of the fourth support plate fixing hole 536 can be 3.5 mm, 4.0 mm, or 4.5 mm.

[0112] As an optional implementation, Figure 19 As shown, the overlapping width W1 of the orthographic projection of the first support frame 421 on the first side rear shell 321 and the orthographic projection of the third support plate 530 on the first side rear shell 321 is 0.5 mm to 3.0 mm.

[0113] In some embodiments of the present disclosure, Figures 9 to 19As shown, the overlapping area of ​​the orthographic projection of the first support frame 421 on the first side rear shell 321 and the orthographic projection of the third support plate 530 on the first side rear shell 321 is the key support area 533, which is used to support the key bracket 420.

[0114] In the width direction of the key support area 533, such as 9 to Figure 19 In the first direction F1 shown, if the width of the key support area 533 is too small, it will not provide good support for the key bracket 420; if the width of the key support area 533 is too large, the distance between the first support plate 510 and the third support plate 530 will be too large, which will increase the thickness of the display device. By making the overlapping width W1 of the orthographic projection of the first support frame 421 on the first side rear shell 321 and the orthographic projection of the third support plate 530 on the first side rear shell 321 be 0.5mm to 3.0mm, the key support area 533 can provide good support for the key bracket 420 without increasing the thickness of the display device. For example, in Figure 19 In the embodiment shown, in the first direction F1, the overlapping width W1 of the orthographic projection of the first support frame 421 on the first side rear shell 321 and the orthographic projection of the third support plate 530 on the first side rear shell 321 can be 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm and 3.0mm, etc.

[0115] As an optional implementation, Figure 15 、 Figure 16 as well as Figure 19 As shown, the button bracket 420 also includes a plurality of first snap-fit ​​structures 423 connected to the first support frame 421. The first snap-fit ​​structure 423 is located on the side of the first support frame 421 away from the first side rear shell 321. The first snap-fit ​​structure 423 is snapped onto the two opposite sides of the button circuit board 430 in the first direction F1. The first direction F1 is a direction perpendicular to the back panel 200.

[0116] In some embodiments of the present disclosure, Figure 15 、 Figure 16 as well as Figure 19As shown, a plurality of first engaging structures 423 can be provided on the first support frame 421. The first engaging structures 423 are located on a side of the first support frame 421 away from the first side rear shell 321, and the first engaging structures 423 are respectively located on two opposite sides of the first support member in the first direction F1. When the key circuit board 430 is installed on the circuit board bracket, the first engaging structures 423 pop open in opposite directions in the first direction F1 to engage the key circuit board 430 between the first engaging structures 423 that are relatively arranged in the first direction F1, so that the first engaging structures 423 can be snapped on two opposite sides of the key circuit board 430 in the first direction F1, thereby supporting the key circuit board 430 on the key bracket 420.

[0117] In some embodiments of the present disclosure, Figure 15 、 Figure 16 、 Figure 19 as well as Figures 34 to 39 As shown, a key avoidance opening 531 is defined on the third support plate 530. The key avoidance opening 531 prevents the orthographic projection of the third support plate 530 on the first side portion 321 from overlapping with the orthographic projection of the key circuit board 430 on the first side portion 321. Optionally, the key avoidance opening 531 can also ensure that the orthographic projection of the first engaging structure 423 on the third support plate 530 is located within the key avoidance opening 531. When the key assembly 400 is assembled on the support bracket 500, the first engaging structure 423 can extend into the key avoidance opening 531. The movement of the first engaging structures 423, which are arranged opposite to each other in the first direction F1, in the first direction F1 is restricted by the key avoidance opening 531. This prevents the first engaging structures 423 from deforming in the first direction F1 and causing the key circuit board 430 to fall off. This further enhances the support and stability of the key bracket 420 for the key circuit board 430 and reduces the risk of deformation and collapse of the key assembly 400 to a certain extent.

[0118] As an optional implementation, Figure 16 As shown, a circuit board positioning portion 424 is provided on one side of the first support frame 421 close to the third support plate 530 , and the circuit board positioning portion 424 abuts against a corner of the key circuit board 430 .

[0119] In some embodiments of the present disclosure, a circuit board positioning portion 424 is provided on one side of the first support frame 421 close to the third support plate 530. When installing the key circuit board 430, the key circuit board 430 can be positioned and fixed on the first support frame 421 by abutting the corner of the key circuit board 430 against the circuit board positioning portion 424.

[0120] As an optional implementation, Figure 14 and Figure 19As shown, the button bracket 420 further includes a second engaging structure 425 , which is disposed on a side of the first engaging structure 423 away from the button circuit board 430 , and abuts against a side of the third support plate 530 close to the first support frame 421 .

[0121] In some implementations of the present disclosure, Figure 14 and Figure 19 As shown, the key bracket 420 also includes a second locking structure 425, which is arranged on a side of the first locking structure 423 away from the key circuit board 430. After the key component 400 is assembled to the support bracket 500, the second locking structure 425 can be made to abut against the side of the third support plate 530 close to the first support frame 421 after the assembled key component 400 is assembled to the support bracket 500, so that the third support plate 530 provides support force in the third direction F3 for the second locking structure 425 and the first locking structure 423, and further provides support force in the third direction F3 for the first support frame 421, thereby reducing the risk of the key component 400 being deformed and collapsed due to pressing to a certain extent.

[0122] As an optional implementation, Figure 15 and Figure 16 As shown, the first support frame 421 includes a first sub-support portion 4211, a second sub-support portion 4212 and at least two third sub-support portions 4213 connecting the first sub-support portion 4211 and the second sub-support portion 4212, and a key body avoidance opening 4214 is formed between adjacent third sub-support portions 4213. The third sub-support portions 4213 and the key body avoidance opening 4214 are alternately arranged in the second direction F2, and the second direction F2 is the length direction of the first support frame 421; the orthographic projection of the third sub-support portion 4213 on the first side rear shell 321 covers the orthographic projection of the first locking structure 423 on the first side rear shell 321.

[0123] In some embodiments of the present disclosure, Figure 15 and Figure 16As shown, the first support frame 421 includes a first sub-support portion 4211, a second sub-support portion 4212 and a third sub-support portion 4213. The first sub-support portion 4211 and the second sub-support portion 4212 are parallel to each other and are strip structures extending along the second direction F2. The third sub-support plate is connected between the first sub-support portion 4211 and the second sub-support portion 4212, and a hollow key body avoidance opening 4214 is formed between two adjacent third sub-support portions 4213, thereby forming an arrangement state on the first support frame 421 in which the third sub-support portion 4213 and the key body avoidance opening 4214 are alternately arranged in the second direction F2, so that the key body 410 can be installed on the first support frame 421 through the key body avoidance opening 4214. Optionally, the first sub-support portion 4211 and the second sub-support portion 4212 can be provided with an elastic clamp extending toward the avoidance opening 4214 of the button body, and the button body 410 is connected by the elastic clamp, so that the button body 410 can be supported on the first support frame 421 and suspended relative to the key circuit board 430 on the side of the key circuit board 430 close to the first side rear shell 321. When the button body 410 is pressed, the button body 410 can be made to abut against the key circuit board 430. After the pressing force is withdrawn, the button body 410 is separated from the key circuit board 430 under the action of the elastic clamp.

[0124] In some embodiments of the present disclosure, Figure 15 and Figure 16 As shown, the orthographic projection of the third sub-support portion 4213 on the first side rear shell 321 covers the orthographic projection of the first clamping structure 423 on the first side rear shell 321, that is, the position of the first clamping structure 423 corresponds to the position of the third sub-support portion 4213. In this case, the structural strength of the first support frame 421 at the first clamping structure 423 can be improved. On the one hand, the ability of the first clamping structure 423 to clamp and fix the key circuit board 430 can be improved, thereby preventing the key circuit board 430 from falling off the first support frame 421; on the other hand, the structural strength of the first support frame 421 can be improved, and the ability of the first support frame 421 to resist collapse and deformation can be improved to a certain extent.

[0125] As an optional implementation, Figures 9 to 11As shown, the first support plate 510 is provided with a first support plate fixing hole 511, so as to be connected to the back plate 200 through the first support plate fixing hole 511, and the first support plate 510 includes a first offset area 512, which is the area where the first support plate fixing hole 511 is provided on the first support plate 510, and the distance between the first offset area 512 and the back plate 200 in the first direction F1 is a first offset distance S1, and the first offset distance S1 is 4.0 mm to 10.0 mm; and / or, the second support plate 520 is provided with a second support plate fixing hole 521, and the second support plate 520 is connected to the back shell 310 through the second support plate fixing hole 521, and the second support plate 520 includes a second offset area, which is the area where the second support plate fixing hole 521 is provided on the second support plate 520, and the distance between the second offset area and the back shell 310 in the first direction F1 is a second offset distance, and the second offset distance is 4.0 mm to 10.0 mm, wherein the first direction F1 is a direction perpendicular to the back plate.

[0126] In some embodiments of the present disclosure, Figures 9 to 11 As shown, the first support plate 510 may be provided with a first support plate fixing hole 511, allowing the first support plate 510 to be connected to the back plate 200 through the first support plate fixing hole 511. The first support plate 510 includes a first offset region 512. The region of the first support plate 510 where the first support plate fixing hole 511 is provided is the first offset region 512. The distance between the first offset region 512 and the back plate 200 in the first direction F1 is a first offset distance S1. In other words, in the first direction F1, the first offset region 512 is warped relative to the region of the first support plate 510 toward the back housing 310. The first offset region 512 is offset away from the back plate 200 by a first offset distance S1 of 4.0 mm to 10.0 mm. When the first support plate 510 and the back plate 200 are connected and fixed via the connector and the first support plate fixing hole 511, a certain first offset distance S1 is ensured between the first support plate fixing hole 511 and the back plate 200, thereby ensuring the required screw-in depth of the connector. In the first direction F1, the first offset distance S1 should not be less than 4.0 mm. If the first offset distance S1 is less than 4.0 mm, the screwing depth of the connector cannot be met, which will lead to an unstable connection between the first support plate 510 and the back plate 200. At the same time, the first offset distance S1 should not exceed 10.0 mm. If the first offset distance S1 exceeds 10.0 mm, the size of the support bracket 500 will be too large and space will be wasted. For example, Figures 9 to 11 As shown, the first offset distance S1 can be 4.0 mm, 5.0 mm, 6.0 mm, 7.0 mm, 8.0 mm, 9.0 mm, 10.0 mm, etc.

[0127] In some embodiments of the present disclosure, the second support plate 520 may optionally be provided with a second support plate fixing hole 521, through which the second support plate 520 is connected to the back shell 310; the second support plate includes a second offset region, where the region of the second support plate 520 where the second support plate fixing hole 521 is provided is the second offset region, and the distance between the second offset region and the back shell 310 in the first direction F1 is a second offset distance (not shown in the figure). That is, in the first direction F1, the second offset region is warped relative to the region of the second support plate 520 in a direction closer to the back plate 200, and the second offset region is offset away from the back shell 310 by a second offset distance of 4.0 mm to 10.0 mm. When the second support plate 520 is connected and fixed to the back shell 310 via the connector and the second support plate fixing hole 521, a certain second offset distance can be ensured between the second support plate fixing hole 521 and the back shell 310, thereby satisfying the screw-in depth of the connector. In the first direction F1, the second offset distance should not be less than 4.0 mm. If the second offset distance is less than 4.0 mm, the screwing depth of the connector cannot be satisfied, resulting in an unstable connection between the second support plate 520 and the back shell 310. At the same time, the second offset distance should not exceed 10.0 mm. If the second offset distance exceeds 10.0 mm, the support bracket 500 will be too large and space will be wasted. For example, the second offset distance can be 4.0 mm, 5.0 mm, 6.0 mm, 7.0 mm, 8.0 mm, 9.0 mm, and 10.0 mm.

[0128] As an optional embodiment, Figures 9 to 21 As shown, the third support plate 530 is perpendicular to the first support plate 510 and the second support plate 520 , and the cross section of the support bracket 500 is U-shaped or I-shaped.

[0129] In some embodiments of the present disclosure, Figures 9 to 21As shown, the third support plate 530 is perpendicular to the first support plate 510, and the third support plate 530 is perpendicular to the second support plate 520. That is to say, the third support plate 530 is perpendicular to the first support plate 510 and the second support plate 520, so that the cross section of the support bracket 500 can be "U"-shaped or "I"-shaped, so that the third support plate 530 can be supported between the first support plate 510 and the second support plate 520, which can ensure that the support structure formed by the first support plate 510, the second support plate 520 and the third support plate 530 is more stable and the structural rigidity and strength of the support bracket 500 are ensured, and the back plate 200 can be fitted with the first support plate 510. When the rear shell 300 is subjected to force, the back shell 310 and the second support plate 520 can be fitted, and at the same time, the third support plate 530 can be fitted with the key bracket 420, so that the support bracket 500 can provide better support for the back plate 200, the back shell 310 and the key bracket 420.

[0130] In some embodiments of the present disclosure, Figures 10 to 14 As shown, the positions where the first support plate 510, the second support plate 520 and the third support plate 530 are connected are respectively located at one end of the first support plate 510 close to the first side rear shell 321 and one end of the second support plate 520 close to the first side rear shell 321. After the first support plate 510, the second support plate 520 and the third support plate 530 are connected to each other, as shown in FIG. Figure 14 As shown, the cross section of the support bracket 500 may be U-shaped.

[0131] In some embodiments of the present disclosure, Figures 20 to 21 As shown, the positions where the first support plate 510 and the second support plate 520 are connected to the third support plate 530 are respectively located in the middle of the first support plate 510 in the third direction F3 and the middle of the second support plate 520 in the third direction F3. After the first support plate 510, the second support plate 520 and the third support plate 530 are connected to each other, as shown in FIG. Figure 21 As shown, the cross section of the support bracket 500 can be made into an I-shape.

[0132] As an optional implementation, Figure 9 、 Figure 14 as well as Figure 29 As shown, the distance between the back plate 200 and the back shell 310 in the first direction F1 is a first distance L1 , which is 0.2 mm to 1.0 mm greater than the height H of the support bracket. The first direction F1 is a direction perpendicular to the back plate 200 .

[0133] In some embodiments of the present disclosure, Figure 9 、 Figure 14 as well as Figure 29As shown, in a direction perpendicular to the back panel 200, i.e., in a first direction F1, the distance between the back panel 200 and the back shell 310 in the first direction F1 is a first spacing L1, and the maximum distance between the first support plate 510 and the second support plate 520 is the height H of the support bracket. Since the support bracket 500 is installed between the back panel 200 and the back shell 310, it is necessary to make the height H of the support bracket compatible with the first spacing L1 between the back panel 200 and the back shell 310. In other words, the height H of the support bracket can be slightly smaller than the first spacing L1 between the back panel 200 and the back shell 310. This ensures that after the first support plate 510 and the second support plate 520 are respectively connected and fixed to the back panel 200 and the back shell 310, an assembly gap of 0.2 mm to 1.0 mm is reserved in the first direction F1, thereby preventing the support bracket 500 from lifting the back shell 310.

[0134] In some embodiments of the present disclosure, Figure 9 、 Figure 14 as well as Figure 29 As shown, in the direction perpendicular to the back panel 200400, that is, in the first direction F1, by making the height H of the support bracket 0.2mm~1.0mm smaller than the first distance L1 between the back panel 200 and the back shell 310, after the support bracket 500 is assembled with the back panel 200 and the back shell 300, an assembly gap of 0.2mm~1.0mm can be provided between the back shell 310 and the second support plate 520, which can prevent the support bracket 500 from lifting the back shell 300 and causing the back shell 300 to be unable to be assembled into place. At the same time, when the back shell 300 is pressed by external force, the back shell 300 can contact the second support plate 520 of the support bracket 500, thereby utilizing the support bracket 500 to provide support for the back shell 300.

[0135] For example, in Figure 9 、 Figure 14 as well as Figure 29 In the embodiment shown, when the first support plate 510 is fixed on the back plate 200 and the second support plate 520 is fixed on the rear shell 300, it is necessary to make the height H of the support bracket in the first direction F1 compatible with the first spacing L1. Under the condition that the first spacing L1 between the back plate 200 and the back shell 310 in the first direction F1 is 28.7 mm to 29.5 mm, the height of the support bracket 500 in the first direction F1 can be made 28.5 mm, so that the height H of the support bracket is 0.2 mm to 1.0 mm smaller than the first spacing L1.

[0136] In some embodiments of the present disclosure, during assembly of the display device, the first support plate 510 of the support bracket 500 can be first connected and locked to the back panel 200 via connectors. The corresponding bases, such as the key assembly 400 and the power jack 940, can then be connected and locked to the third support plate 530 via connectors. The rear housing 300 can then be installed and the back housing 310 can be connected and locked to the second support plate 520 via connectors. After assembly, the key bracket 420 and the third support plate 530 can be fitted with zero clearance. This ensures that all areas of the key bracket 420 are supported by the third support plate 530 when the key body 410 is pressed by external force, thereby preventing deformation of the central area of ​​the key bracket 420 that could affect the user experience. After assembly, a clearance of 0.2 mm to 1.0 mm can be maintained between the back housing 310 and the second support plate 520 in the first direction F1. When there is an assembly gap of 0.2mm to 1.0mm between the back shell 310 and the second support plate 520, it can prevent the support bracket 500 from lifting the back shell 300 and causing the back shell 300 to be unable to be assembled in place. At the same time, when the back shell 310 is pressed by an external force, the back shell 300 can contact the second support plate 520 of the support bracket 500 with a buffer of 0.2mm to 1.0mm, thereby using the support bracket 500 to provide support for the back shell 300. For example, in the first direction F1, the first distance L1 is greater than the height H of the support bracket by 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1.0mm.

[0137] In some cases, the spacing between the wall-mounting studs 230 of a display device may not meet the standard wall-mounting dimensions specified by the International VESA (Video Electronics Standards Association). For example, in some embodiments, the spacing between the wall-mounting studs 230 of a display device is 300mm×300mm, while the standard wall-mounting dimensions specified by the International VESA are 100mm×100mm, 200mm×200mm, 400mm×400mm, and so on. If the display device's own wall-mounting studs 230 are directly used, the commonly available base and wall-mounting bracket cannot be used, requiring custom-made ones, which increases the cost of using the display device.

[0138] In the related art, a flat adapter plate 30 can be added to the display device to convert the spacing of the wall-mounted rivets 230 of the display device itself into the international VESA standard wall-mounted size. However, Figure 6 and Figure 7As shown, one side of the planar adapter plate 30 is connected to the wall-mounted rivet column 230 on the back panel 200 of the display device, and the other side of the planar adapter plate 30 is connected to the newly added adapter column 31. Compared with the thickness of the display device itself, setting the planar adapter plate 30 will cause the display device to increase the thickness of the planar adapter plate 30 and the height of the adapter column 31, that is, this type of planar adapter plate 30 will cause the thickness of the display device to increase, which obviously does not meet the demand for the display device to develop towards thinness and lightness; at the same time, this type of planar adapter plate 30 cannot effectively avoid and isolate high-voltage live devices (such as the power board 910) in the display device, and there are certain defects in insulation protection, which is prone to high-voltage electric shock, thereby causing the display device to fail to pass the national mandatory safety certification.

[0139] As an optional implementation, Figure 9 、 Figures 28 to 33 As shown, the display device also includes an adapter bracket 800, which is located between the back panel 200 and the back shell 310. The adapter bracket 800 includes at least one crest portion 810 and at least one trough portion 820 connected to each other. The shortest distance between the crest portion 810 and the back panel 200 in the first direction F1 is a first distance D1, and the shortest distance between the trough portion 820 and the back panel 200 in the first direction F1 is a second distance D2. The first distance D1 is greater than the second distance D2, and the first direction F1 is a direction perpendicular to the back panel 200.

[0140] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the adapter bracket 800 includes at least one crest portion 810 and at least one trough portion 820 connected to each other, in a direction perpendicular to the back plate 200, that is, in the ... Figures 28 to 33 In the first direction F1 shown, the shortest distance between the crest portion 810 and the back plate 200 in the first direction F1 is a first distance D1, and the shortest distance between the trough portion 820 and the back plate in the first direction F1 is a second distance D2.

[0141] On the one hand, by making the first distance D1 greater than the second distance D2, the crest portion 810 can be offset relative to the trough portion 820 in a direction away from the back panel 200, so as to reserve a larger space between the crest portion 810 and the back panel 200, so that the components on the back panel 200 can be avoided through the crest portion 810, so that a certain distance is maintained between the adapter bracket 800 and the components on the back panel 200, thereby improving the insulation protection capability while avoiding the components on the back panel 200.

[0142] On the second aspect, by making the first distance D1 greater than the second distance D2, the crest portion 810 can be offset relative to the trough portion 820 in a direction away from the back panel 200, so as to reserve a larger space between the crest portion 810 and the back panel 200. The larger space between the crest portion 810 and the back panel 200 can also meet the installation space of the wall-mounted rivet column 230 on the back panel 200, so that the crest portion 810 is connected to the side of the back panel 200 close to the back shell 310 through the wall-mounted rivet column 230; at the same time, by making the first distance D1 greater than the second distance D2, the trough portion 820 can be offset relative to the crest portion 810 in a direction close to the back panel 200, so as to reserve a smaller space between the trough portion 820 and the back panel 200, which is equivalent to reserving a larger space between the trough portion 820 and the back shell 310 and the wall-mounted component, and the smaller space between the trough portion 820 and the back shell 310. The large space can meet the installation space of the adapter rivet column 830, and there is no need to reserve a separate installation space for the adapter rivet column 830 on the side of the adapter bracket 800 away from the back panel 200; in the first direction F1, at least one peak portion 810 is connected to the wall-mounted rivet column 230, and at least one trough portion 820 is connected to the adapter rivet column 830, so that the wall-mounted rivet column 230 and the adapter rivet column 830 can overlap to a certain extent in the first direction F1, saving the combined occupied space of the wall-mounted rivet column 230 and the adapter rivet column 830 in the first direction F1, so that when the display device is connected to the wall-mounted component through the adapter bracket 800, the adapter of the adapter bracket 800 will not significantly increase the distance between the back panel 200 and the wall-mounted component in the first direction F1, and can even reduce the distance between the back panel 200 and the wall-mounted component in the first direction F1, thereby ensuring that the display device has a light and thin characteristic.

[0143] Thirdly, the side of the back panel 200 close to the back shell 310 is connected to at least one peak portion 810, and a first adapter fixing hole 8131 can be set at a position corresponding to the peak portion 810 and the wall-mounted rivet column 230 on the back panel 200, so that the peak portion 810 is connected to the wall-mounted rivet column 230 through the first adapter fixing hole 8131, thereby realizing the connection between the peak portion 810 and the side of the back panel 200 close to the back shell 310; the wall-mounted part is connected to at least one trough portion 820, and an adapter rivet column 830 can be set at a position where the trough portion 820 meets the international VESA standard wall-mounted size, so that the trough portion 820 is connected to the wall-mounted part through the adapter rivet column 830, thereby realizing the connection between the trough portion 820 and the wall-mounted part. Therefore, by setting the adapter bracket 800 in the display device, the spacing of the wall-mounted rivets 230 of the display device itself can be converted to comply with the international VESA standard wall-mounting size, so as to be compatible with various international VESA standard wall-mounting sizes and meet the size requirements of international VESA standard wall-mounting parts.

[0144] Fourthly, the adapter bracket 800 includes at least one crest portion 810 and at least one trough portion 820 connected to each other, which can enable the adapter bracket 800 to form a "wave-like" folding structure in which the crest portions 810 and the trough portions 820 are connected in sequence. The "wave-like" folding structure can enhance the structural strength of the adapter bracket 800 and ensure that the adapter bracket 800 achieves a stable adapter effect.

[0145] In some embodiments of the present disclosure, the connection direction of the crest portion 810 and the trough portion 820 can be adjusted based on the placement of components in the display device, the spacing between the wall-mounting studs 230, and the desired VESA standard wall-mounting dimensions. The crest portion 810 and the trough portion 820 can be connected to each other in the second direction F2 or in the third direction F3. In the following embodiments of the present disclosure, the adapter bracket 800 of the present disclosure is described using the example of the crest portion 810 and the trough portion 820 connected to each other in the third direction F3.

[0146] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the wall-mounted rivet studs 230 are generally arranged on the back panel 200 of the display device. The size of the adapter bracket 800 is related to the spacing size of the wall-mounted rivet studs 230. It is necessary to make the size of the adapter bracket 800 larger than the spacing size of the wall-mounted rivet studs 230; optionally, the spacing size of the wall-mounted rivet studs 230 on the back panel 200 is greater than 10 mm.

[0147] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the size of the adapter bracket 800 is also related to the international VESA standard wall mount size, so the size of the adapter bracket 800 needs to be larger than the corresponding international VESA standard wall mount size. Optionally, the international VESA standard wall mount size can be 100mm×100mm, 200mm×200mm, and 400mm×400mm, etc.

[0148] For example, Figure 9 、 Figures 28 to 33As shown, in the display device, four wall-mounted rivet posts 230 are provided on the back panel 200, and the spacing between the four wall-mounted rivet posts 230 is 300mm×300mm. In order to make the size of the adapter bracket 800 match the spacing size of the wall-mounted rivet posts 230, the size of the adapter bracket 800 needs to be larger than 300mm×300mm. At the same time, the width of the display device is between 300mm and 400mm, and the international VESA standard wall-mounting size that can match the display device is 200mm×200mm, that is, the adapter bracket 800 needs to be connected to the wall-mounting part with the international VESA standard wall-mounting size of 200mm×200mm, then the adapter bracket 800 can be connected to the wall-mounting part through four adapter rivet posts 830, and the spacing size between the four adapter rivet posts 830 needs to meet 200mm×200mm, so the adapter rivet posts 830 can be set at the corresponding position of the trough part according to this size. In order to make the size of the adapter bracket 800 match the international VESA standard wall-mounting size, the size of the adapter bracket 800 needs to be larger than 200mm×200mm. To sum up, the size of the adapter bracket 800 can be (310mm~320mm)×(310mm~320mm). For example, the length and width of the adapter bracket 800 can be 310mm, 311mm, 312mm, 313mm, 314mm, 315mm, 316mm, 317mm, 318mm, 319mm and 320mm respectively.

[0149] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the adapter bracket 800 is connected to the wall-mounted rivet column 230 on the back panel 200 through the first adapter fixing hole 8131 on the peak portion 810. For example, the adapter bracket 800 and the wall-mounted rivet column 230 can be connected and fixed together by tapping M4 or tapping M6, so the inner diameter of the first adapter fixing hole 8131 needs to match the diameter of the tapping M4 or tapping M6.

[0150] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the adapter bracket 800 is connected to the wall mount through the adapter rivet stud 830 on the trough portion 820. For example, the wall mount rivet stud 830 can be riveted to the adapter bracket, and the inner screw hole of the adapter rivet stud 830 is matched with the diameter of the tapping M4 or tapping M6. Then, the wall mount can be connected and fixed together with the adapter rivet stud 830 using the tapping M4 or tapping M6.

[0151] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33As shown, the adapter bracket 800 may be provided with an avoidance notch 8132 so that the adapter bracket 800 can avoid some connection harnesses or device structures provided on the back panel 200, thereby facilitating the connection of the display or avoiding affecting the normal use of the device structure.

[0152] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the span of the crest portion 810 and the trough portion 820 can be adjusted according to the setting position of the device in the display apparatus, the spacing size of the wall-mounted rivet studs 230 and the international VESA standard wall-mounted size to be converted, that is, the size of the crest portion 810 in the third direction F3 and the size of the trough portion 820 in the third direction F3 are adjusted, so that the crest portion 810 and the trough portion 820 can adapt to the spacing size requirements of the wall-mounted rivet studs 230 on the back panel 200 and the spacing size requirements of the adapter rivet studs 830 connected to the wall-mounted parts, and can also enable the adapter bracket 800 to effectively avoid the devices and other structures on the back panel 200.

[0153] As an optional implementation, Figure 9 、 Figures 28 to 33 As shown, the display device also includes a power board 910, which is arranged on the side of the back panel 200 close to the back shell 310, and the peak portion 810 includes a first peak portion 811, and the positive projection of the first peak portion 811 on the back panel 200 at least partially overlaps with the positive projection of the power board 910 on the back panel 200.

[0154] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, by making the orthographic projection of the first crest portion 811 on the back panel 200 at least partially overlap with the orthographic projection of the power board 910 on the back panel 200, in the overlapping area of ​​the orthographic projection of the first crest portion 811 on the back panel 200 and the orthographic projection of the power board 910 on the back panel 200, since a large space is reserved between the first crest portion 811 and the back panel 200, the power board 910 can be avoided by the first crest portion 811 to avoid interference between the adapter bracket 800 and the power board 910.

[0155] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the size of the first crest portion 811 in the third direction F3 can be set according to the size of the power board 910 in the third direction F3, and the size of the first crest portion in the third direction F3 can be made greater than or equal to the size of the power board 910 in the third direction F3 to avoid interference between the trough portion 820 connected to the first crest portion and the power board 910. Figure 9 、 Figures 28 to 33In the illustrated embodiment, the dimension of the first crest portion 811 in the third direction F3 may be 86 mm, so that the dimension of the first crest portion 811 in the third direction F3 matches the dimension of the power board 910 in the third direction F3.

[0156] As an optional implementation, Figure 9 、 Figures 28 to 33 As shown, a power supply device 911 is provided on the side of the power board 910 away from the backboard 200, the minimum distance between the power supply device 911 and the first crest portion 811 in the first direction F1 is the third distance D3, the minimum distance between the backboard 200 and the power board 910 in the first direction F1 is the fourth distance, and the ratio of the third distance D3 to the fourth distance D4 is 1:2 to 2:1.

[0157] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, a power supply device 911 is provided on the side of the power supply board 910 away from the back panel 200. By making the ratio of the third distance D3 to the fourth distance D4 be 1:2 to 2:1, a certain distance can be maintained between the power supply device 911 and the first crest portion 811, and between the power supply board 910 and the back panel 200, so as to avoid the risk of leakage and electric shock caused by high-voltage arc. At the same time, the adapter bracket can provide a larger space between the first crest portion and the back panel through the undulating structure design of crests and troughs, so that the third distance D3 and the fourth distance D4 can be increased to a certain extent, that is, the safety distance between the power supply device 911 and the first crest portion 811, and between the power supply board 910 and the back panel 200 can be improved.

[0158] In some embodiments, the ratio of the third distance D3 to the fourth distance D4 may be 1:2, 1:1.5, 1:1, 1.5:1, 2:1, etc.

[0159] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, by making the third distance D3 greater than or equal to 6.0 mm, it is ensured that there is a sufficient distance between the power supply device 911 and the first peak portion 811, thereby ensuring that there is a sufficient insulation distance between the power supply device 911 and the adapter bracket 800, so as to avoid the risk of high-voltage electric shock caused by contact between the power supply device 911 and the adapter bracket 800.

[0160] In some embodiments, the third distance D3 may be greater than or equal to 6.0 mm. For example, the third distance D3 may be 6.0 mm, 7.0 mm, 8.0 mm, 9.0 mm, 10.0 mm, 11.0 mm, 12.0 mm, 13.0 mm, 14.0 mm, 15.0 mm, 16.0 mm, 17.0 mm, 18.0 mm, 19.0 mm, and 20.0 mm, etc.

[0161] In some embodiments, the third distance D3 may be greater than or equal to 16.0 mm. For example, the third distance D3 may be 16.0 mm, 17.0 mm, 18.0 mm, 19.0 mm, 20.0 mm, 21.0 mm, 22.0 mm, 23.0 mm, 24.0 mm, and 25.0 mm.

[0162] As an optional implementation, Figure 9 、 Figures 28 to 33 As shown, the display device also includes a system board 920, which is arranged on a side of the back panel 200 close to the back shell 310, and the peak portion 810 includes a second peak portion 812, and the orthographic projection of the second peak portion 812 on the back panel 200 at least partially overlaps with the orthographic projection of the system board 920 on the back panel 200.

[0163] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the system board 920 is the "brain" and "heart" of the display device. If it is damaged, the display device will not work properly. By making the orthographic projection of the second crest portion 812 on the back panel 200 at least partially overlap with the orthographic projection of the system board 920 on the back panel 200, in the overlapping area of ​​the orthographic projection of the second crest portion 812 on the back panel 200 and the orthographic projection of the system board 920 on the back panel 200, since a large space is reserved between the second crest portion 812 and the back panel 200, the system board 920 can be avoided by the second crest portion 812 to avoid interference between the adapter bracket 800 and the system board 920.

[0164] In some embodiments of the present disclosure, according to the spacing distance between the second crest portion 812 and the first crest portion 811 in the third direction F3, a trough portion 820 or a plurality of trough portions 820 and crest portions 810 alternately connected in sequence may be provided between the second crest portion 812 and the first crest portion 811, thereby adding a bending structure to the adapter bracket 800, which can improve the structural strength of the adapter bracket 800 to a certain extent. For example, in the case of Figure 9 、 Figures 28 to 33 In the illustrated embodiment, the second wave crest portion 812 is connected to the first wave crest portion 811 via a wave trough portion 820 .

[0165] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the size of the second crest portion 812 in the third direction F3 can be set according to the size of the system board 920 in the third direction F3, and the size of the second crest portion in the third direction F3 can be made greater than or equal to the size of the system board 920 in the third direction F3, so as to avoid interference between the trough portions 820 on both sides of the second crest portion in the third direction F3 and the system board 920. Figure 9 、 Figures 28 to 33 In the illustrated embodiment, the dimension of the second wave crest portion 812 in the third direction F3 may be 45 mm, so that the dimension of the second wave crest portion 812 in the third direction F3 matches the dimension of the system board 920 in the third direction F3.

[0166] As an optional implementation, Figure 9 、 Figures 28 to 33 As shown, a system component 921 is provided on the side of the system board 920 away from the back plate 200 , and the distance between the system component 921 and the second crest portion 812 in the first direction F1 is a fifth distance D5 , which is greater than or equal to 6.0 mm and less than the third distance D3 .

[0167] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, a system component 921 is provided on a side of the system board 920 away from the backplane 200. By ensuring that a fifth distance D5 between the system component 921 and the second crest portion 812 in the first direction F1 is greater than or equal to 6.0 mm, sufficient distance is ensured between the system component 921 and the second crest portion 812, thereby ensuring a sufficient mating distance between the system component 921 and the adapter bracket 800. This, to a certain extent, reduces the risk of short circuits or damage to the system board 920 due to contact. Optionally, the system board 920 has a lower risk of electrical leakage than the power board 910, so the fifth distance D5 is smaller than the third distance D3.

[0168] In some embodiments of the present disclosure, the fifth distance D5 is greater than or equal to 6.0 mm. For example, the fifth distance D5 may be 6.0 mm, 7.0 mm, 8.0 mm, 9.0 mm, 10.0 mm, 11.0 mm, 12.0 mm, 13.0 mm, 14.0 mm, and 15.0 mm, etc.

[0169] In some embodiments of the present disclosure, the fifth distance D5 is greater than or equal to 10.0 mm. For example, the fifth distance D5 may be 10.0 mm, 11.0 mm, 12.0 mm, 13.0 mm, 14.0 mm, 15.0 mm, etc.

[0170] As an optional implementation, Figure 9 、 Figures 28 to 33As shown, the crest portion 810 includes a third crest portion 813, and the third crest portion 813 is provided with a first transition fixing hole 8131. The crest portion 810 is connected to the back plate 200 through the first transition fixing hole 8131. In some embodiments of the present disclosure, as Figure 9 、 Figures 28 to 33 As shown, the crest portion 810 further includes a third crest portion 813, which is provided with a first adapter fixing hole 8131. The adapter bracket 800 is connected to the wall-mounted rivet stud 230 on the back panel 200 through the first adapter fixing hole 8131 on the third crest portion 813, thereby achieving the connection between the adapter bracket 800 and the back panel 200. At the same time, there is a relatively large space between the third crest portion 813 and the back panel 200, allowing the third crest portion 813 to avoid the wall-mounted rivet stud 230 on the back panel 200. The third crest portion 813 can be connected to the internal thread of the wall-mounted rivet stud 230 via a connecting piece passing through the first adapter fixing hole 8131, thereby achieving the purpose of fixing the third crest portion 813 to the wall-mounted rivet stud 230.

[0171] In some embodiments of the present disclosure, depending on the distance between the third wave crest 813 and the first wave crest 811 in the third direction F3, a trough 820 or a plurality of alternately connected troughs 820 and wave crests 810 may be provided between the third wave crest 813 and the first wave crest 811; and depending on the distance between the third wave crest 813 and the second wave crest 812 in the third direction F3, a trough 820 or a plurality of alternately connected troughs 820 and wave crests 810 may be provided between the third wave crest 813 and the second wave crest 812. This adds a bending structure to the adapter bracket 800, which can improve the structural strength of the adapter bracket 800 to a certain extent.

[0172] In some embodiments of the present disclosure, the number and location of the third wave crests 813 can be determined based on the number and spacing of the wall-mounted rivets 230. In the embodiment of the present disclosure, the number and location of the third wave crests 813 are described by taking the back panel 200 as an example with four wall-mounted rivets 230. Figure 9 、 Figures 28 to 33In the illustrated embodiment, four wall-mounted rivet posts 230 are provided on the back panel 200, and accordingly, two third wave peaks 813 can be provided in the adapter bracket 800. The setting positions of the two third wave peaks 813 can be determined according to the spacing distance of the wall-mounted rivet posts 230. One of the third wave peaks 813 is connected to the first wave peak 811 through the trough 820, and is provided with two first adapter fixing holes 8131 for connecting with the two wall-mounted rivet posts 230, and the spacing between the two first adapter fixing holes 8131 corresponds to the spacing between the two wall-mounted rivet posts 230; the other third wave peak 813 is connected to the second wave peak 812 through the trough 820, and is provided with two first adapter fixing holes 8131 for connecting with the other two wall-mounted rivet posts 230, and the spacing between the two first adapter fixing holes 8131 corresponds to the spacing between the two wall-mounted rivet posts 230.

[0173] In one embodiment of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the size of the third wave crest portion 813 in the third direction F3 can be set according to factors such as its own installation position, the size of the wall-mounted rivet stud 230 and the size of the connecting screw. At least the size of the third wave crest portion 813 in the third direction F3 needs to be larger than the outer diameter of the wall-mounted rivet stud 230 and the outer diameter of the screw head of the connecting screw. Figure 9 、 Figures 28 to 33 In the illustrated embodiment, the outer diameter of the wall-mounted studs 230 on the back panel 200 of the display module 100 can be 12 mm. The screw heads of the selected connecting screws have an outer diameter of 16 mm. Therefore, the dimension of the third wave crest 813 in the third direction F3 must be at least 16 mm to match the dimensions of the connecting screws. In this embodiment, the adapter bracket 800 includes two third wave crests 813. The third wave crest 813 spaced apart from the first wave crest 811 can have a dimension of 20 mm in the third direction F3. The dimension of the third wave crest 813 spaced apart from the second wave crest 812 in the third direction F3 can be 49 mm in the third direction F3, taking into account the dimensions of the first wave crest 811 and the second wave crest 812 in the third direction F3, the spacing between the wall-mounted studs 230, and the dimension of the troughs 820 connecting the wave crests 810 in the third direction F3.

[0174] As an optional implementation, Figure 9 、 Figures 28 to 33 As shown, the trough portion 820 includes at least two first trough portions 821 , and each first trough portion 821 is provided with at least two adapter rivet studs 830 , which are connected to the wall hanging piece.

[0175] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the trough portion 820 includes at least two first trough portions 821, each of which is provided with at least two adapter studs. This allows the adapter bracket 800 to be connected to the wall mount via the adapter studs 830 on the first trough portions 821, thereby achieving connection between the adapter bracket 800 and the wall mount. Furthermore, the first trough portions 821 are recessed toward the back panel 200. When the adapter studs 830 are provided in the first trough portions 821, they can overlap with the first trough portions 821 to a certain extent in the first direction F1. This allows full utilization of the space in the first direction F1, allowing the display device's overall dimensions in the first direction F1 to be reused, thereby reducing the thickness of the display device to a certain extent. Optionally, when the first trough portion 821 does not interfere with the device structure on the back panel 200, the second distance D2 can be shortened as much as possible, that is, the first trough portion 820 can be brought as close to the back panel 200 as possible, thereby increasing the degree of overlap between the transfer rivet column 830 and the first trough portion 821 in the first direction F1, thereby increasing the reuse rate of the size of the entire display device in the first direction F1.

[0176] In some embodiments of the present disclosure, the location of the first trough portion 821 can be determined according to the international VESA standard wall-mounting size. Figure 9 、 Figures 28 to 33 In the illustrated embodiment, two first wave troughs 821 may be provided in the adapter bracket 800, and the setting positions of the two first wave troughs 821 may be determined according to the international VESA standard wall-mounting dimensions. That is, the setting positions of the two first wave troughs 821 may be determined according to the spacing of the adapter rivet posts 830 that conform to the international VESA standard wall-mounting dimensions. One of the first wave troughs 821 is located between the first wave crest portion 811 and the second wave crest portion 812, and two adapter rivet posts 830 are provided thereon; the other first wave trough 821 is located between the second wave crest portion 812 and the third wave crest portion 813, and another two adapter rivet posts 830 are provided thereon.

[0177] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the size of the first wave valley portion 821 in the third direction F3 can be set according to factors such as its own location, the size of the interconnected wave crest portions 810 in the third direction F3, and the size of the transfer rivet stud 830. At least the size of the first wave valley portion 821 in the third direction F3 needs to be larger than the outer diameter of the transfer rivet stud 830. Figure 9 、 Figures 28 to 33In the illustrated embodiment, the size of the first trough portion 821 located between the first trough portion 811 and the second trough portion 812 in the third direction F3 can be set according to the spacing between the first trough portion 811 and the second trough portion 812 in the third direction F3, that is, according to the spacing between the system board 920 and the power board 910 in the third direction F3. The size of the first trough portion 821 in the third direction F3 can be made smaller than the spacing between the system board 920 and the power board 910 in the third direction F3 to avoid interference between the first trough portion 821 and the power board 910 or the system board 920. The size of the first trough portion 821 located between the first trough portion 811 and the second trough portion 812 in the third direction F3 can be 42 mm, so that the size of the first trough portion 821 in the third direction F3 matches the spacing between the system board 920 and the power board 910 in the third direction F3. The size of the first wave valley portion 821 located between the second wave peak portion 812 and the third wave peak portion 813 in the third direction F3 can be set according to the distance between the second wave peak portion 812 and the third wave peak portion 813 in the third direction F3. The size of the first wave valley portion 821 located between the second wave peak portion 812 and the third wave peak portion 813 in the third direction F3 can also be 42 mm.

[0178] As an optional implementation, Figure 9 、 Figures 28 to 33 As shown, the distance between the center of the pattern formed by the orthographic projection of all transfer rivet studs 830 on the back plate 200 and the center of the back plate 200 is less than 10.0 cm.

[0179] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, at least two wall-mounted rivet studs 830 are provided on the first wave trough portion 821, the adapter bracket 800 includes at least two first wave trough portions 821, and the fixed adapter bracket 800 has at least four wall-mounted rivet studs 830. The orthographic projections of the wall-mounted rivet studs 830 on the back panel 200 can be connected to form a certain pattern. By making the distance between the center of the pattern and the center of the back panel 800 less than 10.0 cm, the center of the pattern formed by the orthographic projection of the adapter rivet studs 830 on the back panel 200 can be located within 10.0 cm of the center of the back panel 200, thereby ensuring that multiple wall-mounted rivet studs 830 are located relatively close to the center of the back panel 200. After the adapter bracket 800 is connected to the wall-mounted component through the wall-mounted rivet studs 830, the force on the adapter bracket 800 and the back panel 20 can be made more balanced.

[0180] As an optional implementation, Figure 9 、 Figures 28 to 33As shown, the trough portion 820 further includes a second trough portion 822 , the orthographic projection of the second trough portion 822 on the backplane 200 is staggered with the orthographic projections of the power board 910 and the system board 920 on the backplane 200 , and the second trough portion 822 is located between adjacent crest portions 810 .

[0181] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, by providing a second trough 822 between adjacent crests 810, the orthographic projection of the second trough 822 on the backplane 200 is staggered with the orthographic projections of the power board 910 and the system board 920 on the backplane 200. This can avoid interference between the second trough 822 and the power board 910 and the system board 920, and can also increase the number of bends of the adapter bracket 800 through the second trough 822, thereby increasing the rigidity of the adapter bracket itself. Figure 9 、 Figures 28 to 33 As shown, the trough portion 820 located between the first crest portion 811 and the second crest portion 812 can be recorded as the second crest portion 822. The second crest portion 822 is mainly used to increase the bending structure of the adapter bracket 800 to increase the structural strength of the adapter bracket 800. Since the second crest portion 822 does not need to be provided with an adapter rivet 830, the size of the second crest portion 822 in the third direction F3 can be determined according to the distance between the first crest portion 811 and the second crest portion 812. When the position and size of the first crest portion 811 and the position and size of the third crest portion 813 are determined, the size of the second crest portion 822 can be naturally determined. For example, in the case of Figure 9 、 Figures 28 to 33 In the illustrated embodiment, the dimension of the second wave valley 822 in the third direction F3 is 30 mm.

[0182] As an optional implementation, Figure 9 、 Figures 28 to 33 As shown, the difference between the first distance D1 of the third wave crest portion 813 and the second distance D2 of the first wave trough portion 821 is less than or equal to the dimension of the adapter rivet stud 830 in the first direction F1.

[0183] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33As shown, the difference between the first distance D1 of the third wave crest portion 813 and the second distance D2 of the first wave trough portion 821 is the depth of the first wave trough portion 821 in the first direction. By making the difference between the first distance D1 of the third wave crest portion 813 and the second distance D2 of the first wave trough portion 821 less than or equal to the size of the adapter rivet column 830 in the first direction F1, it can be ensured that after the adapter rivet column 830 is set on the side of the first wave trough portion 821 away from the back plate 200, the adapter rivet column 830 is not completely hidden in the first wave trough portion 821, which can ensure that the adapter rivet column 830 can be connected to the wall hanging part.

[0184] As an optional implementation, Figure 9 、 Figures 28 to 33 As shown, the trough portion 820 includes a connecting portion arranged opposite to each other in the third direction F3, the connecting portion is connected to the crest portion 810, and an angle between the connecting portion and the crest portion in a plane is greater than 0° and less than 90°.

[0185] In some embodiments of the present disclosure, Figure 9 、 Figures 28 to 33 As shown, the trough portion 820 includes a connecting portion relatively arranged in the third direction F3. Then, in the third direction F3, the trough portion 820 can be connected to the peak portion 810 through the connecting portion. By making the angle between the connecting portion and the plane where the peak portion 810 is located greater than 0° and less than 90°, the connecting portion can be tilted relative to the peak portion 810, and at the same time, the connecting portion can be tilted relative to the main part of the trough portion 820. The connecting portion in the tilted state can change the force direction of the peak portion 810 and the trough portion 820 to a certain extent, from the force perpendicular to the plane where the peak portion 810 is located to the force tilted to the plane where the peak portion 810 is located, and from the force perpendicular to the plane where the trough portion 820 is located to the force tilted to the plane where the trough portion 820 is located, thereby improving the force condition of the adapter bracket 800 and improving its structural strength and impact resistance. Optionally, the angle between the connecting portion and the crest portion in the plane can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc.

[0186] In some embodiments of the present disclosure, Figure 28 、 Figures 34 to 36 as well as Figure 39 As shown, the rear shell 300 is provided with an adapter through hole 312 corresponding to the position of the adapter rivet column 830 on the adapter bracket 800, so that the connecting part can pass through the adapter through hole 312 and connect with the wall hanging part and the adapter rivet column 830 respectively, thereby connecting the wall hanging part to the adapter bracket 800.

[0187] In a display device, such as Figure 7 and Figure 8 As shown, the back shell 310 needs to reserve a terminal opening 311 to correspond to the position of the functional terminal 930 on the back plate 200. However, since the assembly accuracy of the back shell 310 is relatively low, generally ±0.5mm, a separate terminal baffle 20 can generally be provided on the back plate 200, and the functional terminal 930 is set on the terminal baffle 20, and then the terminal baffle 20 is used to cooperate with the larger terminal opening 311 reserved on the back shell 310. The terminal baffle 20 ensures that the fitting clearance at the functional terminal 930 meets the national mandatory safety certification requirements, while reducing the requirements for the assembly accuracy of the back shell 300. If the terminal baffle 20 is not used, the functional terminal 930 is directly matched with the terminal opening 311 reserved on the back shell 310. On the one hand, it is easy for the matching clearance between the terminal opening 311 reserved on the back shell 310 and the functional terminal 930 to be too large, exceeding 1.0 mm, resulting in the display device failing to pass the national mandatory safety certification; on the other hand, it is easy for the matching clearance between the terminal opening 311 reserved on the back shell 300 and the functional terminal 930 on the back plate 200 to be too small, resulting in the functional terminal 930 being unable to be normally plugged in and out. Therefore, in the related art, it is generally necessary to additionally set a terminal baffle 20 on the back plate 200, and set the functional terminal 930 on the terminal baffle 20 to match the opening reserved on the back shell 300. However, this method increases the number of structural parts in the display device, and increases material costs and labor costs.

[0188] As an optional implementation, Figure 28 and Figure 29 、 Figures 34 to 40 As shown, in the display device, a second positioning rivet 220 is provided on the side of the adapter bracket 800 close to the back shell 310 and / or a side of the back plate 200 close to the back shell 310; a positioning sleeve 313 is provided on the side of the back shell 310 close to the back plate 200, and the positioning sleeve 313 is sleeved on the second positioning rivet 220; the back shell 310 is provided with a back shell 300 fixing hole that penetrates the positioning sleeve 313, and the back shell 310 is connected to the second positioning rivet 220 through the back shell 300 fixing hole.

[0189] In some embodiments of the present disclosure, Figure 28 and Figure 29 、 Figures 34 to 40As shown, a second positioning rivet 220 is provided on one side of the adapter bracket 800 close to the back shell 310 and / or a side of the back plate 200 close to the back shell 310, and a positioning sleeve 313 is provided on one side of the back shell 310 close to the back plate 200. When the back shell 300 is assembled in the display device, the positioning sleeve 313 can be sleeved on the second positioning rivet 220. The positioning sleeve 313 is sleeved on the second positioning rivet 220 to form a sleeve-type limiting structure, which can improve the accuracy of the positioning connection between the back shell 300 and the adapter bracket 800 or the back plate 200, thereby improving the assembly accuracy of the back shell 300; for example, the assembly accuracy of the back shell 300 can be improved to ≤±0.25mm, and after the assembly accuracy of the back shell 300 is improved , which can ensure that the terminal opening 311 reserved on the rear shell 300 corresponds to the position of the functional terminal 930 on the back plate 200, so that the terminal opening 311 can be directly reserved on the rear shell 300 and the terminal opening 311 can be aligned with the functional terminal 930 on the back plate 200, without having to set up the terminal baffle 20 separately, and the fitting clearance between the terminal opening 311 reserved on the shell and the functional terminal 930 on the back plate 200 can be controlled to be below 0.5mm, avoiding the fitting clearance between the terminal opening 311 reserved on the rear shell 300 and the functional terminal 930 on the back plate 200 being too large or too small, thereby meeting the requirements of the national mandatory safety certification, and can also avoid the risk of the functional terminal 930 not being able to be normally plugged in and out to a certain extent.

[0190] In some embodiments of the present disclosure, optionally, when the second positioning rivet column 220 is set on the adapter bracket 800, the second positioning rivet column 220 and the adapter rivet column 830 can be an integrated structure, that is, the second positioning rivet column 220 can be used as the adapter rivet column 830 for connection with the wall hanging part, and can also be used as a positioning structure for positioning connection with the rear shell 300.

[0191] In some embodiments of the present disclosure, Figure 28 and Figure 29 、 Figures 34 to 40 As shown, optionally, the radius of the second positioning rivet 220 matches the inner radius of the positioning sleeve 313, so that the radius of the second positioning rivet 220 and the inner radius of the positioning sleeve 313 can be 2.0mm to 5.0mm respectively. If the radius of the second positioning rivet 220 and the inner radius of the positioning sleeve 313 are less than 2.0mm, the second positioning rivet 220 and the positioning sleeve 313 are too small, and it is difficult to align them during assembly; if the radius of the second positioning rivet 220 and the inner radius of the positioning sleeve 313 are greater than 5.0mm, the second positioning rivet 220 and the positioning sleeve 313 are too large, which will result in waste of material for the second positioning rivet 220 and the positioning sleeve 313. For example, in Figures 34 to 35, the second positioning rivet 220 and the positioning sleeve 313 are too large, and the material for the second positioning rivet 220 and the positioning sleeve 313 is too large. Figure 40In the illustrated embodiment, the radius of the second positioning rivet stud 220 may be 3.0 mm. Correspondingly, the inner radius of the positioning sleeve 313 is 3.5 mm, and the positioning accuracy of the second positioning rivet stud 220 is ±0.25 mm.

[0192] In some embodiments of the present disclosure, Figure 28 and Figure 29 、 Figures 34 to 40 As shown, the radius of the through hole in the positioning sleeve 313 is related to the type of screw used to connect the second positioning rivet 220 to the positioning sleeve 313. For example, the radius of the through hole in the positioning sleeve 313 can be 2.0 mm, and the radius of the corresponding screw is 1.0 mm to 1.5 mm. The radius of the through hole in the positioning sleeve 313 is 0.5 mm to 1.0 mm larger than the radius of the corresponding screw.

[0193] In some embodiments of the present disclosure, Figure 28 and Figure 29 、 Figures 34 to 40 As shown, the height of the positioning sleeve 313 is related to the distance between the back plate 200 and the back shell 300 in the first direction F1, and the height of the positioning sleeve 313 can be equal to the distance between the back plate 200 and the back shell 310 in the first direction F1. For example, the height of the positioning sleeve 313 can be 29 mm.

[0194] In some embodiments of the present disclosure, the outer diameter of the positioning sleeve 313 is larger than the corresponding screw cap diameter to ensure that there is sufficient space within the positioning sleeve 313 to accommodate the corresponding screw cap. The outer diameter of the positioning sleeve 313 is at least 1.0 mm larger than the diameter of the screw cap. For example, the outer diameter of the positioning sleeve 313 can be 11.0 mm, the wall thickness of the positioning sleeve 313 is 2.0 mm, and the corresponding screw cap diameter can be 7.5 mm.

[0195] In some embodiments of the present disclosure, optionally, a plurality of second positioning rivet columns 220 are provided on a side of the back panel 200 adjacent to the back shell 310, and the plurality of second positioning rivet columns 220 can be evenly distributed in a middle area of ​​the back panel 200 adjacent to the back shell 310; accordingly, a plurality of positioning sleeves 313 are provided on a side of the back shell 310 adjacent to the back panel 200 in a one-to-one correspondence with the plurality of second positioning rivet columns 220.

[0196] During the assembly process of the display device, the positioning accuracy of the outer frame 600 is poor, which easily leads to the problem of uneven width of the black border of the display device. Figures 2 to 5 As shown, the outer frame 600 itself has a certain dimensional tolerance, which is generally ±0.5mm. Due to the dimensional tolerance and assembly accuracy of the outer frame 600, when the outer frame 600 is assembled with the display module 100, Figure 4One side of the display device shown can achieve zero clearance between the outer frame 600 and the display module 100. Figure 5 There is a 1.0 mm gap on the other side of the display device, which causes the black border area 120 of the display device to have an uneven width, affecting the appearance of the display device and even causing the front outer frame 610 to block the display area 110 of the display module 100 .

[0197] As an optional implementation, Figures 22 to 27 As shown, the display device further includes an outer frame 600 and at least two positioning brackets 700 . The outer frame 600 is buckled on the display module 100, and the outer frame 600 includes a front outer frame 610 and a side outer frame 620 connected to the front outer frame 610. The front outer frame 610 is located on the light-emitting side of the display module 100, and the side outer frame 620 is surrounded by the display module 100; the positioning bracket 700 includes a first positioning plate 710, a second positioning plate 720 and a positioning connecting plate 730, the first positioning plate 710 is fixed to the side of the front outer frame 610 close to the display module 100, the second positioning plate 720 is fixed to the side of the back plate 200 away from the display module 100, and the positioning connecting plate 730 connects the first positioning plate 710 and the second positioning plate 720, wherein the back plate 200 is provided with a first positioning rivet 210 on the side close to the back shell 310, and the second positioning plate 720 is provided with a positioning groove 721, and the positioning groove 721 matches the first positioning rivet 210 for positioning.

[0198] In some embodiments of the present disclosure, Figures 22 to 27As shown, the outer frame 600 is buckled onto the display module 100. The outer frame 600 includes a front outer frame 610 and side outer frames 620 connected to the front outer frame 610. The front outer frame 610 is located on the light-emitting side of the display module 100, and the side outer frames 620 are arranged around the display module 100. The arrangement of the outer frame 600 can make the appearance of the display module more beautiful and neat. The positioning bracket 700 is used to position and connect the outer frame 600 and the back plate. The positioning bracket 700 includes a first positioning plate 710, a second positioning plate 720, and a positioning connection plate 730. The first positioning plate 710 is fixed to the side of the front outer frame 610 close to the display module 100, the second positioning plate 720 is fixed to the side of the back plate 200 away from the display module 100, and the positioning connection plate 730 connects the first positioning plate 710 and the second positioning plate 720. At the same time, the back panel 200 is provided with a first positioning rivet 210 on the side close to the back shell 310. The first positioning rivet 210 is used for positioning and installing the positioning bracket 700. The second positioning plate 720 is provided with a positioning groove 721. By matching the positioning groove 721 with the first positioning rivet 210 on the back panel 200, the second positioning plate 720 can be positioned relative to the back panel 200; thereby achieving the positioning connection between the second positioning plate 720 and the back panel 200. At the same time, based on the positioning connection between the second positioning plate 720 and the back panel 200, the first positioning plate 710 can also be connected to the front outer frame 610 of the outer frame 600. In other words, the front outer frame 610 and the back panel 200 can be assembled and connected together through the positioning bracket 700, and the positioning bracket 700 can play a role in positioning and connection; at the same time, during the assembly process, the outer frame 600 can be accurately positioned relative to the back panel 200 in both the length direction and the width direction of the front outer frame 610, that is, in the following example. Figures 22 to 27 The front outer frame 610 and the back panel 200 are precisely positioned and connected in the fourth direction F4 and the fifth direction F5 shown, so that the assembly accuracy of the outer frame 600 is improved to ≤±0.25mm, thereby avoiding, to a certain extent, the uneven black edge width caused by the low assembly accuracy of the outer frame 600. At the same time, by connecting and locking the first positioning plate 710 to the front outer frame 610 in the outer frame 600, it is possible to avoid using screws or other connecting parts to lock the side outer frame 620 of the outer frame 600. Therefore, screws or other connecting parts used for the outer frame 600 and the positioning bracket 700 can be located on the side of the front outer frame 610 close to the back panel 200, so that screws or other connecting parts used for the outer frame 600 and the positioning bracket 700 can be hidden inside the display device, which can improve the aesthetics of the display device to a certain extent.

[0199] As an optional implementation, Figures 22 to 27As shown, the first positioning plate 710 is provided with a first positioning and fixing hole 711 to be connected to the front outer frame 610 through the first positioning and fixing hole 711; the second positioning plate 720 is provided with a second positioning and fixing hole 722 and a third positioning and fixing hole 723 to be connected to the back plate 200 through the second positioning and fixing hole 722 and the third positioning and fixing hole 723; the maximum dimension of the first positioning and fixing hole 711 and the third positioning and fixing hole 723 in the length direction of the front outer frame 610 is a first dimension N1, and the maximum dimension of the first positioning and fixing hole 711 and the third positioning and fixing hole 723 in the width direction of the front outer frame 610 is a second dimension N2, and the first dimension N1 is greater than the second dimension N2.

[0200] In some embodiments of the present disclosure, Figures 22 to 27 As shown, the first positioning plate 710 is provided with a first positioning and fixing hole 711, so that the first positioning plate 710 can be connected to the front outer frame 610 through the first positioning and fixing hole 711. The second positioning plate 720 can be provided with a second positioning and fixing hole 722, so that the second positioning plate 720 can be connected and fixed to the back plate 200 through the second positioning and fixing hole 722.

[0201] In some embodiments of the present disclosure, Figures 22 to 27 As shown, in order to ensure that the position of the second positioning plate 720 after being connected to the back plate 200 is accurate and stable, the second positioning fixing hole 722 can be a circular hole. The second positioning plate 720 can be fixed to the back plate 200 by tapping M3, and the diameter of the tapping M3 is 2.5mm. The inner diameter of the second positioning fixing hole 722 is larger than the diameter of the tapping M3. For example, if the inner diameter of the second positioning fixing hole 722 is larger than the diameter of the tapping M3 by more than 0.5mm, the inner diameter of the second positioning fixing hole 722 is greater than or equal to 3.5mm. For example, the inner diameter of the second positioning fixing hole 722 can be 2.0mm, 3.0mm, 3.5mm, 4.0mm, and 4.5mm, etc.

[0202] In some embodiments of the present disclosure, Figures 22 to 27 As shown, the maximum dimension of the first positioning and fixing hole 711 in the longitudinal direction of the front outer frame 610 is the first dimension N1, that is, Figures 22 to 27 In the fourth direction F4 shown, the maximum size of the first positioning and fixing hole 711 is the first size N1; the maximum size of the first positioning and fixing hole 711 in the width direction of the front outer frame 610 is the second size N2, that is, Figures 22 to 27In the fifth direction F5 shown, the maximum size of the first positioning and fixing hole 711 is the second size N2. By making the first size N1 larger than the second size N2, the first positioning and fixing hole 711 can be made into a runway-type through-hole structure. By making the first size N1 larger than the second size N2 of the first positioning and fixing hole 711, the first positioning plate 710 can be conveniently connected to the front outer frame 610 through the first positioning and fixing hole 711 on the basis of the positioning connection between the second positioning plate 720 of the positioning bracket 700 and the back plate 200; in the fifth direction F5, the front outer frame 610 can be accurately fixed relative to the back plate 200 by the positioning bracket 700, that is, the front outer frame 610 can be fixed relative to the display module set on the back plate 200. The position of 100 is precisely fixed, thereby improving the assembly accuracy of the outer frame 600 and the display module 100, and can avoid, to a certain extent, the uneven black edge width caused by the front outer frame 610 blocking the display area 110 of the display module 100 and the assembly offset of the outer frame 600 relative to the display module 100; in the fourth direction F4, the first positioning fixing hole 711 has a certain assembly space, so that the first positioning fixing hole 711 and the fixing hole reserved on the front outer frame 610 are aligned and connected in the fourth direction F4.

[0203] In some embodiments of the present disclosure, Figures 22 to 27 As shown, optionally, a third positioning fixing hole 723 can be provided on the second positioning plate 720, so that the second positioning plate 720 can be further connected and fixed to the back plate 200 through the second positioning fixing hole 722 and the third positioning fixing hole 723, thereby improving the stability of the second positioning plate 720 connected and fixed to the back plate 200.

[0204] In some embodiments of the present disclosure, Figures 22 to 27 As shown, the maximum dimension of the third positioning and fixing hole 723 in the longitudinal direction of the front outer frame 610 is the first dimension N1, that is, Figures 22 to 27 In the fourth direction F4 shown, the maximum size of the third positioning and fixing hole 723 is the first size N1; the maximum size of the third positioning and fixing hole 723 in the width direction of the front outer frame 610 is the second size N2, that is, Figures 22 to 27In the fifth direction F5 shown, the maximum dimension of the third positioning and fixing hole 723 is the second dimension N2. By making the first dimension N1 larger than the second dimension N2, the third positioning and fixing hole 723 can be configured as a racetrack-shaped through-hole. By making the first dimension N1 larger than the second dimension N2, the third positioning and fixing hole 723 can be easily aligned and further secured to the second positioning plate 720, provided that the second positioning plate 720 is positioned and secured to the backplane 200 via the second positioning and fixing hole 722 and the positioning groove 721. In addition, in the fourth direction F4, the first dimension N1 of the third positioning and fixing hole 723 is relatively large, so that the third positioning and fixing hole 723 has a certain assembly space in the fourth direction F4, so that the third positioning and fixing hole 723 can be aligned and connected with the fixing hole reserved on the back panel 200 in the fourth direction F4; in the fifth direction F5, the second dimension N2 of the third positioning and fixing hole 723 is relatively small, which can match the size of the connecting part of the third positioning and fixing hole 723, so that in the fifth direction F5, the position of the third positioning and fixing hole 723 can be accurately fixed relative to the position of the back panel 200, that is, the second positioning plate 720 can be accurately fixed relative to the position of the back panel 200.

[0205] In some embodiments of the present disclosure, Figures 22 to 27 As shown, the first positioning hole 711 on the first positioning plate 710 can be fixed to the front outer frame 610 by tapping M3. Then, the first dimension N1 of the first positioning hole 711 can be 4.0 mm, and the second dimension N2 of the first positioning hole 711 can be 3.5 mm. The second dimension N2 of the first positioning hole 711 matches the dimension of the tapping M3, which can ensure that the position of the first fixed positioning hole in the fifth direction F5 is fixed. The first dimension N1 of the first positioning hole 711 has a certain margin compared to the dimension of the tapping M3, so that a certain assembly margin can be provided in the fourth direction F4. Similarly, the third positioning hole 723 of the second positioning plate 720 can be fixed to the back plate 200 by tapping M3. Then, the first dimension N1 of the third positioning hole 723 can be 4.0 mm, and the second dimension N2 of the third positioning hole 723 can be 3.5 mm.

[0206] In some embodiments of the present disclosure, in the length direction of the front outer frame 610, that is, in the Figures 22 to 27In the fourth direction F4 shown, the size of the positioning bracket 700 can be 20mm to 100mm. By making the size of the positioning bracket 700 in the fourth direction F4 20mm to 100mm, it is convenient to set the first positioning fixing hole 711, the second positioning fixing hole 722, the third positioning fixing hole 723 and the positioning groove 721 on the positioning bracket 700, and it is also beneficial to ensure the positioning accuracy of the positioning bracket 700. In the fourth direction F4, if the size of the positioning bracket 700 is less than 20mm, the size of the positioning bracket 700 is too small, and the first positioning fixing hole 711, the second positioning fixing hole 722, the third positioning fixing hole 723 and the positioning groove 721 cannot be conveniently set on the positioning bracket 700, which is not convenient for positioning; if the size of the positioning bracket 700 is greater than 100mm, the size of the positioning bracket 700 is too large, the processing tolerance of the positioning bracket 700 itself is large, and the accuracy of the positioning bracket 700 cannot be ensured. In the width direction of the front outer frame 610, that is, Figures 22 to 27 In the fifth direction F5 shown, the size of the positioning bracket 700 can be 20mm to 60mm. By making the size of the positioning bracket 700 in the fifth direction F5 20mm to 60mm, it is not only convenient to set the first positioning fixing hole 711, the second positioning fixing hole 722, the third positioning fixing hole 723 and the positioning groove 721 on the positioning bracket 700, but also helps to ensure the positioning accuracy of the positioning bracket 700. In the fifth direction F5, if the size of the positioning bracket 700 is less than 20mm, the width of the positioning bracket 700 is too small, and the first positioning fixing hole 711, the second positioning fixing hole 722, the third positioning fixing hole 723 and the positioning groove 721 cannot be conveniently set on the positioning bracket 700, which is not convenient for positioning; if the size of the positioning bracket 700 is greater than 60mm, the size of the positioning bracket 700 is too large, the processing tolerance of the positioning bracket 700 itself is large, and the manufacturing accuracy and positioning accuracy of the positioning bracket 700 cannot be ensured. For example, in the case of Figures 22 to 27 In the illustrated embodiment, the size of the positioning bracket 700 in the length direction of the front outer frame 610, i.e., in the fourth direction F4, can be 30 mm; in the width direction of the front outer frame 610, i.e., in the fifth direction F5, the size of the positioning bracket 700 can be 31 mm.

[0207] In some embodiments of the present disclosure, Figures 22 to 27 As shown, the vertical distance between the first positioning plate 710 and the second positioning plate 720 can be adaptively adjusted according to the distance between the front outer frame 610 of the display device and the back plate 200. Generally, in the direction perpendicular to the back plate 200, that is, in the direction perpendicular to the back plate 200, the distance between the front outer frame 610 of the display device and the back plate 200 is less than or equal to 20 mm. Accordingly, in the direction perpendicular to the back plate 200, that is, in the direction perpendicular to the back plate 200, the distance between the front outer frame 610 of the display device and the back plate 200 is less than or equal to 20 mm. Figures 22 to 27In the first direction F1 shown, the size of the positioning bracket 700 needs to be less than or equal to 20 mm. Figures 22 to 27 In the illustrated embodiment, the size of the positioning bracket 700 may be 7 mm.

[0208] In some embodiments of the present disclosure, Figures 22 to 27 As shown, the orthographic projection of the first positioning rivet 210 on the back plate 200 is circular, and correspondingly, the orthographic projection of the positioning groove 721 on the back plate 200 is semicircular or circular, which can match the limiting portion.

[0209] In some embodiments of the present disclosure, Figures 22 to 24 As shown, the orthographic projection of the first positioning rivet 210 on the back plate 200 is circular, so that the orthographic projection of the positioning groove 721 on the back plate 200 is semicircular and matches the limiting portion. During the assembly process, the positioning groove 721 is aligned with the first positioning rivet 210 on the back plate 200 to achieve the positioning of the positioning bracket 700 relative to the back plate 200. The positioning bracket 700 can then be connected and locked to the back plate 200 through the second positioning and fixing holes 722 and the third positioning and fixing holes 723, and the positioning bracket 700 can be connected and locked to the front outer frame 610 through the first positioning and fixing holes 711. Optionally, the first positioning rivet 210 with a circular orthographic projection can facilitate its production and convenient positioning of the positioning bracket 700.

[0210] In some embodiments of the present disclosure, Figures 25 to 27 As shown, the orthographic projection of the first positioning rivet 210 on the back panel 200 is circular, so that the orthographic projection of the positioning groove 721 on the back panel 200 is circular and matches the limiting portion. During the assembly process, the positioning groove 721 is sleeved on the first positioning rivet 210, so that the positioning bracket 700 can be positioned relative to the back panel 200; thereafter, the positioning bracket 700 can be connected and locked to the back panel 200 through the second positioning fixing hole 722 and the third positioning fixing hole 723, and the positioning bracket 700 can be connected and locked to the front outer frame 610 through the first positioning fixing hole 711.

[0211] As an optional implementation, Figures 22 to 27 As shown, the minimum dimension of the positioning groove 721 in the length direction and the width direction of the front outer frame 610 is a positioning dimension N3, and the positioning dimension N3 is greater than or equal to 1.0 mm.

[0212] In some embodiments of the present disclosure, Figures 22 to 27 As shown, the minimum size of the positioning groove 721 in the length direction and the width direction of the front outer frame 610 is the positioning size N3, that is, Figures 22 to 27In the fourth and fifth directions F4 and F5, the minimum dimension of the positioning groove 721 is the positioning dimension N3. By ensuring that the positioning dimension N3 of the positioning groove 721 is greater than or equal to 1.0 mm, the first positioning stud 210 should have corresponding dimensions to the positioning groove 721, thereby ensuring the positioning effectiveness of the positioning groove 721 and the first positioning stud 210. If the positioning dimension N3 of the positioning groove 721 is less than 1.0 mm, the positioning effectiveness is poor, making it inconvenient to use for positioning and installing the positioning bracket 700.

[0213] like Figures 22 to 24 As shown, when the orthographic projection of the positioning groove 721 on the back plate 200 is semicircular, the positioning dimension N3 is the radius of the positioning groove 721, and the radius of the positioning groove 721 is greater than or equal to 1.0 mm. Accordingly, the diameter of the first positioning rivet 210 is greater than or equal to 2.0 mm; Figures 25 to 27 As shown, when the orthographic projection of the positioning groove 721 on the back plate 200 is circular, the positioning dimension N3 is the diameter of the positioning groove 721, and the diameter of the positioning groove 721 is greater than or equal to 2.0 mm. Accordingly, the diameter of the first positioning rivet 210 is greater than or equal to 2.0 mm.

[0214] In some embodiments of the present disclosure, Figures 22 to 27 As shown, the first positioning rivet 210 is a cylinder, and the diameter of the first positioning rivet 210 can be 2.00mm to 5.00mm. Correspondingly, the diameter of the positioning groove 721 is 2.00mm to 5.00mm. While ensuring the limiting effect of the first positioning rivet 210, it can also prevent the first positioning rivet 210 from being too large and the second positioning plate 720 from being too large due to the first positioning rivet 210 being too large. If the diameter of the first positioning rivet 210 is greater than 5.00mm, there will be no significant improvement in the positioning effect, and it will also lead to waste of materials and processing resources. For example, Figures 22 to 27 As shown, the diameter of the first locating stud 210 can be 2.00 mm, 2.25 mm, 2.50 mm, 2.75 mm, 3.00 mm, 3.25 mm, 3.50 mm, 3.75 mm, 4.00 mm, or 5.00 mm, etc. Correspondingly, the diameter of the locating groove 721 can be 2.00 mm, 2.25 mm, 2.50 mm, 2.75 mm, 3.00 mm, 3.25 mm, 3.50 mm, 3.75 mm, 4.00 mm, or 5.00 mm, etc. Optionally, the matching accuracy between the first locating stud 210 and the locating groove 721 is ±0.125 mm to ensure the positioning accuracy of the first locating stud 210 and the locating groove 721.

[0215] In some other embodiments of the present disclosure, the orthographic projection of the first positioning rivet 210 on the back plate 200 may also be rectangular, triangular, or the like. Accordingly, the orthographic projection of the positioning groove 721 on the back plate 200 needs to match the orthographic projection of the first positioning rivet 210 on the back plate 200. Figures 22 to 27 As shown, optionally, a limiting groove 611 is provided on one side of the front outer frame 610 adjacent to the back plate 200 , and the limiting groove 611 is used to accommodate the first positioning plate 710 to limit the position of the first positioning plate 710 on the front outer frame 610 .

[0216] In some embodiments of the present disclosure, Figures 22 to 27 As shown, optionally, in the length direction of the front outer frame 610, that is, Figures 22 to 27 In the fourth direction F4 shown, the size of the limiting groove 611 in the fourth direction F4 matches the size of the first positioning plate 710 in the fourth direction F4.
