Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a display device. Background Technology

[0002] For LED display devices, the OD value (optical distance) affects the display effect. Currently, the OD value is usually determined by the size of the back panel cavity. Based on this, to change the OD value of existing products, it is usually necessary to design a new back panel and frame according to the required OD value, resulting in large mold costs and hindering the reduction of production costs. Utility Model Content

[0003] This invention provides a display device that reduces the number of structural components that need to be replaced when changing the OD value of the display device, thereby helping to reduce production costs.

[0004] To achieve the above objectives, this utility model provides a display device, comprising:

[0005] Back panel, the back panel having an accommodating space inside, the back panel comprising:

[0006] Base plate; and

[0007] Side plate, the side plate being connected to the bottom plate;

[0008] A light panel is disposed within the accommodating space, and the light panel is connected to the base plate;

[0009] A diffuser plate is disposed within the accommodating space, and the diffuser plate is located on the side of the lamp plate opposite to the base plate;

[0010] A display panel is disposed on the side of the diffuser plate opposite to the lamp plate; and

[0011] The frame assembly includes:

[0012] A first plastic frame, the first plastic frame comprising:

[0013] The first support is fixedly connected to the side of the diffuser plate facing the lamp plate;

[0014] A second support portion is connected to the side of the first support portion facing the light panel, and the end of the second support portion away from the first support portion abuts against the side of the side plate opposite to the bottom plate; and

[0015] The second adhesive frame is fixedly connected to the first adhesive frame, and the second adhesive frame includes:

[0016] The third support is connected between the display panel and the diffuser plate.

[0017] The display device provided by this utility model features a frame assembly, which includes a first frame and a second frame. The first frame supports a diffuser plate, and the second frame supports a display panel. The first frame includes a second support portion that abuts against a side plate, such that the distance (OD value) between the diffuser plate and the lamp plate depends on the sum of the heights of the side plate and the second support portion. When it is necessary to change the OD value of the display device, the back plate structure can be kept unchanged, and the height of the second support portion can be adjusted to change the distance between the diffuser plate and the lamp plate. Therefore, the above-mentioned display device only requires changing the structure of the first frame, while keeping other structural components and the assembly method unchanged, to achieve the change of the OD value, effectively reducing mold costs and thus lowering production costs.

[0018] In some possible implementations, the first support portion is detachably connected to the second support portion.

[0019] In the above implementation scheme, by designing the first support part and the second support part to be detachably connected, the OD value can be changed by replacing the second support part with a different height, which is convenient for operation.

[0020] In some possible implementations, the first support portion is bonded to the second support portion.

[0021] In the above implementation scheme, the first support part and the second support part are bonded together, which is convenient to operate and helps to achieve the fixing effect of the first support part and the second support part.

[0022] In some possible implementations, the first support portion has a slot on the side facing the lamp panel, and the second support portion is engaged with the slot.

[0023] In the above implementation scheme, fixing the first support and the second support by embedding the second support into the slot helps to ensure that the first support and the second support are relatively fixed.

[0024] In some possible implementations, the first support portion and the second support portion are an integral structure.

[0025] In the above implementation scheme, the first support part and the second support part are an integral structure, which is beneficial to improving the structural stability of the first frame.

[0026] In some possible implementations, the first adhesive frame further includes:

[0027] A first fixing part is connected to the first support part, and the first fixing part is located on the side of the side plate away from the accommodating space;

[0028] The third support portion has a limiting groove on the side opposite to the display panel, and the first fixing portion is engaged with the limiting groove.

[0029] In the above implementation scheme, by engaging the first fixing part with the slot of the third support part, the first frame and the second frame can be fixed, which helps to ensure the overall structural stability of the frame assembly.

[0030] In some possible implementations, the second frame further includes:

[0031] The second fixing part is connected to the third support part. The second fixing part is located on the side of the first fixing part away from the side plate, and the second fixing part abuts against the first fixing part.

[0032] In the above embodiment, the second frame includes a second fixing part that abuts against the first fixing part. By increasing the contact area between the two, the fixing effect between the first frame and the second frame is enhanced.

[0033] In some possible implementations, the first adhesive frame further includes:

[0034] A limiting part is connected to the first support part, and one end of the limiting part away from the first support part abuts against the side of the lamp panel opposite to the base plate.

[0035] In the above implementation scheme, by setting a limiting part and abutting the limiting part against the lamp panel, the fixing effect between the lamp panel and the base plate can be enhanced.

[0036] In some possible implementations, the first adhesive frame further includes:

[0037] The fourth support is connected to the side of the second support facing the lamp plate. The fourth support is located between the second support and the limiting part. The end of the fourth support away from the first support abuts against the side of the base plate facing the diffuser plate.

[0038] In the above implementation scheme, by providing a fourth support part that abuts against the base plate, the fixing effect between the first rubber frame and the back plate can be enhanced.

[0039] In some possible implementations, a reinforcing rib is connected between the fourth support portion and the limiting portion.

[0040] In the above implementation scheme, the structural stability of the first frame can be improved by setting reinforcing ribs. Attached Figure Description

Detailed Implementation

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0057] refer to Figure 1 and Figure 2 The display device in this embodiment may include a back plate 100, a lamp plate 200, a diffuser plate 300, a display panel 400, and a frame assembly 500.

[0058] In this embodiment, OD can be understood as optical distance, specifically, the distance between the lamp plate 200 and the diffuser plate 300 in the thickness direction of the back plate 100. When the OD value is changed, the position of the diffuser plate 300 can be adjusted so that the diffuser plate 300 is closer to or farther away from the lamp plate 200, thereby adjusting the distance between the diffuser plate 300 and the lamp plate 200.

[0059] Specifically, such as Figure 2 As shown, the back panel 100 may include a base plate 110 and a side plate 120. The side plate 120 is connected to the base plate 110, and the side plate 120 and the base plate 110 cooperate to form an accommodating space. A lamp panel 200 and a diffuser plate 300 are disposed within the accommodating space. The lamp panel 200 can be fixedly connected to the base plate 110, and the diffuser plate 300 is spaced apart from the lamp panel 200. The display panel 400 is located on the side of the diffuser plate 300 away from the lamp panel 200. In this case, the light emitted by the lamp panel 200 can be evenly illuminated onto the display panel 400 under the diffusion effect of the diffuser plate 300, thereby ensuring the display effect of the display panel 400.

[0060] The frame assembly 500 can be fixed to the back panel 100, for example, by means of a snap fastener. The frame assembly 500 may include a first frame 510 and a second frame 520. The first frame 510 may include a first support portion 511 and a second support portion 512, the first support portion 511 being located on the side of the diffuser plate 300 facing the lamp panel 200, and the second support portion 512 being connected to the side of the first support portion 511 facing the lamp panel 200.

[0061] The first support portion 511 can be arranged parallel to the bottom plate 110 of the back plate 100, and the first support portion 511 is fixedly connected to the diffuser plate 300 so that the first support portion 511 can support the diffuser plate 300. For example, the first support portion 511 can be fixed to the diffuser plate 300 by adhesive bonding in order to ensure the fixing effect between the first support portion 511 and the diffuser plate 300.

[0062] The second support portion 512 can be disposed directly opposite the side plate 120, and the second support portion 512 can also be perpendicular to the first support portion 511. One end of the second support portion 512 away from the first support portion 511 abuts against the side of the side plate 120 facing the diffuser plate 300, so that the second support portion 512 and the side plate 120 remain relatively fixed. For example, to improve the fixing effect between the second support portion 512 and the side plate 120, the second support portion 512 and the side plate 120 can also be bonded together with an adhesive layer.

[0063] Continue to refer to Figure 2 The first frame 510 may further include a limiting portion 513, which is connected to the side of the first support portion 511 facing the lamp panel 200. The limiting portion 513 is inclined to the first support portion 511 and extends toward the base plate 110 so that the end of the limiting portion 513 away from the first support portion 511 can abut against the lamp panel 200, thereby fixing the limiting portion 513 and the lamp panel 200 relatively. That is, there is an angle between the limiting portion 513 and the lamp panel 200, and this angle is not a right angle. In this way, the dimension of the first support portion 511 extending toward the accommodating space can be reduced. By setting the projection plane to a plane parallel to the base plate 110, the orthographic projection of the first support portion 511 on the projection plane can be avoided from overlapping with the orthographic projection of the lamp panel 200 on the projection plane, thereby ensuring the light output effect of the lamp panel 200.

[0064] On the other hand, it is also understandable that when the limiting part 513 is designed to be inclined to the first support part 511, it is also beneficial to improve the limiting effect of the first frame 510 on the lamp plate 200, so as to enhance the fixing effect between the lamp plate 200 and the base plate 110.

[0065] Continue to refer to Figure 2The second frame 520 may include a third support portion 521, which is fixedly connected to the first frame 510. The third support portion 521 is located between the diffuser plate 300 and the display panel 400. One side of the third support portion 521 is connected to the diffuser plate 300, and the other side is connected to the display panel 400. This allows the third support portion 521 to support the display panel 400 while also keeping the display panel 400 and the diffuser plate 300 relatively fixed, thus ensuring the display effect of the display panel 400.

[0066] It should be understood that the display device in this embodiment is designed with a frame assembly 500, which includes a first frame 510 and a second frame 520 that are relatively fixed. The first frame 510 is used to fix the diffuser plate 300 and the lamp plate 200, and the second support portion 512 abuts against the side plate 120. Figure 2 and Figure 3 In this case, the optical distance OD depends on the sum of the heights of the side plate 120 and the second support 512. When the OD value needs to be changed, the size of the back plate 100 can be kept unchanged, while the size of the first frame 510 can be changed to increase or decrease the height of the second support 512, thereby adjusting the distance between the diffuser plate 300 and the lamp plate 200. Therefore, in this embodiment, when changing the OD value, the display device only needs to change the size of the first frame 510; other structural components do not need to be redesigned, and the overall structure of the display device does not need to be changed, effectively reducing production costs.

[0067] In some embodiments, continue to refer to Figure 2 The first frame 510 may further include a first fixing part 514. The first fixing part 514 is connected to the end of the first support part 511 away from the limiting part 513, that is, the first fixing part 514 and the limiting part 513 are respectively connected to opposite sides of the first support part 511. The first fixing part 514 is located on the side of the side plate 120 away from the receiving space and extends along the height direction of the side plate 120, that is, the first fixing part 514 is located outside the back plate 100. At this time, the first fixing part 514 can also abut against the surface of the side plate 120 away from the receiving space to enhance the fixing effect between the first frame 510 and the back plate 100.

[0068] For example, the first fixing part 514 and the side plate 120 can also be connected by adhesive, which can further improve the fixing effect between the first glue frame 510 and the back plate 100.

[0069] In this embodiment, the first fixing part 514 is fixed to the second adhesive frame 520 so that the first adhesive frame 510 and the second adhesive frame 520 remain fixed together. Specifically, see also... Figure 2 and Figure 4The first fixing part 514 can be provided on the side of the first support part 511 facing the diffuser plate 300, and the third support part 521 can be provided on the side of the first support part 511 facing the first support part 511 with a limiting groove 523. The first fixing part 514 can be snapped into the limiting groove 523 to achieve the fixing between the first frame 510 and the second frame 520.

[0070] Furthermore, such as Figure 2 As shown, the display device in this embodiment may further include an optical film 600, which is disposed between the diffuser plate 300 and the display panel 400, and is fixedly connected to the diffuser plate 300.

[0071] Based on this, continue to refer to Figure 2 and Figure 4 In some alternative embodiments, the third support portion 521 may include a first support segment 5211 and a second support segment 5212, the first support segment 5211 and the second support segment 5212 extending along the arrangement direction of the side plate 120 and the lamp plate 200 on the same side, wherein the first support segment 5211 is located on the side of the second support segment 5212 facing the outside of the back plate 100.

[0072] The orthographic projection of the first support segment 5211 on the projection plane does not overlap with the orthographic projection of the optical film 600 on the projection plane, and the orthographic projection of the first support segment 5211 on the projection plane overlaps with the orthographic projection of the diffuser plate 300 on the projection plane. Thus, the first support segment 5211 is located between the diffuser plate 300 and the display panel 400 to maintain a relatively fixed relationship between the diffuser plate 300 and the display panel 400, and the second support segment 5212 is located between the optical film 600 and the display panel 400 to maintain a relatively fixed relationship between the optical film 600 and the display panel 400.

[0073] The second support section 5212 is fixedly connected to the optical film 600 and the display panel 400 on opposite sides, respectively. The second support section 5212 is connected to the non-display area of ​​the display panel 400 to prevent the display area of ​​the display panel 400 from being affected.

[0074] The height of the first support segment 5211 is greater than the height of the second support segment 5212. Since the optical film 600 has a certain thickness, the first support segment 5211 can protrude beyond the second support segment 5212 on the side facing the optical film 600, so that the first support segment 5211 can contact the diffuser plate 300. At this time, the opposite sides of the first support segment 5211 are fixedly connected to the display panel 400 and the diffuser plate 300, respectively.

[0075] In this embodiment, a certain gap can be maintained between the first support section 5211 and the optical film 600. When the optical film 600 is heated and expands, the gap between the first support section 5211 and the optical film 600 can provide expansion space for the optical film 600, thus avoiding the optical film 600 from contacting and deforming with the first support section 5211 and causing wrinkles.

[0076] Similarly, a certain gap can be maintained between the diffuser plate 300 and the first fixing part 514 to provide expansion space for the diffuser plate 300 to expand due to heat.

[0077] Continue to refer to Figure 4 The first support segment 5211 extends outward toward the back plate 100 along the arrangement direction of the first support segment 5211 and the second support segment 5212. The limiting groove 523 is provided on the side of the first support segment 5211 facing the side plate 120 so that the limiting groove 523 can be directly opposite the first fixing part 514, so that the first fixing part 514 is engaged in the limiting groove 523.

[0078] It is worth mentioning that, since the height of the first support segment 5211 is greater than the height of the second support segment 5212, i.e., the height of the first support segment 5211 is larger, the depth of the limiting groove 523 can be increased when setting the limiting groove 523. This can increase the contact area between the first fixing part 514 and the limiting groove 523, thereby achieving a better fixing effect.

[0079] A guide surface may also be provided at the opening of the limiting groove 523. When the first fixing part 514 is assembled with the limiting groove 523, the guide surface can guide the first fixing part 514, making it easier for the first fixing part 514 to be inserted into the limiting groove 523, so as to complete the assembly of the first fixing part 514 and the first support section 5211.

[0080] Refer again Figure 2 In this embodiment, the second frame 520 may further include a second fixing part 522, which is connected to the third support part 521. Specifically, the second fixing part 522 is connected to one end of the first support section 5211 that is away from the second support section 5212. The second fixing part 522 extends along the height direction of the side plate 120, that is, the second fixing part 522 is arranged parallel to the first fixing part 514.

[0081] The second fixing part 522 is located on the side of the first fixing part 514 away from the side plate 120. In this case, the side of the second fixing part 522 facing the first fixing part 514 can abut against the first fixing part 514, thereby increasing the contact area between the first fixing part 514 and the second fixing part 522. Thus, with the cooperation of the limiting groove 523 and the second fixing part 522, the fixing effect between the first adhesive frame 510 and the second adhesive frame 520 can be enhanced.

[0082] Furthermore, in the height direction of the side panel 120, the second fixing part 522 partially overlaps with the side panel 120, so that the second fixing part 522, the first fixing part 514, and the side panel 120 can be stacked. This not only improves the sealing effect inside the back panel 100, which helps prevent light leakage, but also improves the fixing effect between the frame assembly 500 and the side panel 120.

[0083] In some embodiments, to facilitate changing the height of the second support portion 512, the second support portion 512 and the first support portion 511 can be detachably connected. When it is necessary to change the OD value of the display device, the second support portion 512 of the corresponding height can be assembled with the first support portion 511 to meet the requirements of different OD values. In this way, during the production stage, the overall structure of the first frame 510 does not need to be changed; only the second support portions 512 of different heights need to be processed to meet the assembly of display devices with different OD values, which is simple, efficient, and can better save production costs.

[0084] In some alternative embodiments, the second support portion 512 and the first support portion 511 can be fixed together by adhesive bonding to maintain the fixing effect between the first support portion 511 and the second support portion 512. When assembling the first support portion 511 and the second support portion 512, an adhesive layer can be applied to the side of the second support portion 512 facing the first support portion 511, and then the second support portion 512 and the first support portion 511 can be bonded together using the adhesive layer.

[0085] In some alternative implementations, refer to Figure 5 The first support portion 511 may have a slot 5111 on the side facing the lamp panel 200, and the second support portion 512 is engaged in the slot 5111 to achieve a fixed connection between the second support portion 512 and the first support portion 511. For example, the second support portion 512 may be interference-fitted with the slot 5111 to ensure the fixing effect between the first support portion 511 and the second support portion 512.

[0086] Specifically, when the second support part 512 is snapped into the slot 5111, the second support part 512 can be embedded into the slot 5111 so that the end of the second support part 512 abuts against the bottom wall of the slot 5111 and the side of the second support part 512 abuts against the side wall of the slot 5111.

[0087] In this embodiment, when it is necessary to change the OD value of the display device, the first support 511 can be kept unchanged, and the second support 512 of different height can be replaced and fixed to the slot 5111, thereby changing the distance between the first support 511 and the base plate 110.

[0088] Alternatively, the height of the second support portion 512 can be kept constant, and the depth of the slot 5111 can be changed to adjust the depth of the second support portion 512 embedded in the first support portion 511, thereby changing the height of the part of the second support portion 512 that protrudes from the first support portion 511, and thus changing the distance between the first support portion 511 and the base plate 110.

[0089] In some alternative embodiments, the second support 512 and the slot 5111 can also be fixed together by a snap-fit ​​structure. Specifically, refer to... Figure 6 and Figure 7 The inner wall of the slot 5111 may be provided with multiple sets of buckles 5112, which are spaced apart along the depth direction of the slot 5111. Each set of buckles 5112 may include multiple buckles 5112 evenly distributed around the circumference of the slot 5111, or each set of buckles 5112 may be a complete ring of buckles 5112 extending around the circumference of the slot 5111. Correspondingly, the second support part 512 is provided with hooks 5121 corresponding to each set of buckles 5112. When the second support part 512 is assembled with the first support part 511, the hooks 5121 on the surface of the second support part 512 can engage with one of the sets of buckles 5112, thereby achieving the fixation between the second support part 512 and the first support part 511.

[0090] like Figure 8 and Figure 9 As shown, when it is necessary to change the OD value of the display panel 400, the second support 512 can be moved relative to the slot 5111 to engage the second support 512 with the buckle 5112 corresponding to the OD value, thereby changing the height of the portion of the second support 512 that protrudes from the first support 511.

[0091] To facilitate the movement of the second support portion 512 relative to the slot 5111 and to ensure the effective engagement of the hooks 5121 and buckles 5112 of the second support portion 512, each set of buckles 5112 may, exemplarily, have an inclined surface on the side facing the side plate 120. The inclined surface can guide the hooks 5121, allowing the second support portion 512 to quickly pass over the buckles 5112 near the opening of the slot 5111 and engage with the buckles 5112 near the bottom of the slot 5111 when the second support portion 512 moves toward the inside of the slot 5111. The side of each set of buckles 5112 facing away from the side plate 120 is flat to increase the contact area between the buckles 5112 and the hooks 5121, thus preventing the buckles 5112 from disengaging from the hooks 5121.

[0092] Let the first force be the force that inserts the second support part 512 into the slot 5111, and the second force be the force that removes the second support part 512 from the slot 5111 or pulls the second support part 512 outward relative to the slot 5111. It is understandable that the second force is significantly greater than the first force, thus ensuring a good fixation effect between the second support part 512 and the slot 5111 after they are assembled in place. Furthermore, adjusting the OD value is convenient; it does not require replacing the first adhesive frame 510, but only adjusting the relative position between the second support part 512 and the first support part 511.

[0093] In some embodiments, the first support portion 511 and the second support portion 512 can also be an integral structure, so that the structure between the first support portion 511 and the second support portion 512 is stable and can effectively ensure that the distance between the diffuser plate 300 and the lamp plate 200 is fixed.

[0094] Based on this, when it is necessary to change the OD value, simply replace the first frame 510 and change the height of the second support 512 to achieve the change of the OD value.

[0095] It is worth mentioning that when designing the dimensions of the first frame 510, the original dimensions of the first frame 510 can be designed to fit the maximum OD value of the display device; that is, the height of the second support 512 is adapted to the maximum OD value. When it is necessary to change the OD value later, the second support 512 can be cut to make its height meet the OD value, which is convenient. In this case, it is equivalent to the first support 511 moving downward relative to the lamp panel 200, thereby adjusting the distance between the diffuser plate 300 and the lamp panel 200.

[0096] Assuming the original height of the second support 512 is 3mm, which can be adapted to the OD of the display device (7mm), the OD value of the display device can be switched within the range of 4mm to 7mm. For example... Figure 10 As shown, when the OD value of the display device is changed to 4mm, it can be understood that the second support part 512 is removed, so that the first support part 511 directly overlaps the side plate 120, and the first support part 511 and the side plate 120 abut against each other, thereby achieving the fixation between the first frame 510 and the side plate 120.

[0097] It should be noted that in this embodiment, when the second support portion 512 needs to be cut, the first fixing portion 514 and the limiting portion 513 can also be cut accordingly so that the first frame 510 as a whole can match the back plate 100.

[0098] In some alternative implementations, taking the original height of the second support 512 as 3mm, which can be adapted to the OD of the display device of 7mm as an example, the distance between the first fixing part 514 and the base plate 110 in the height direction of the side plate 120 can be greater than or equal to 3mm. In this case, when changing the OD value of the display device, even if the second support 512 is completely removed, so that the first support 511 directly overlaps the side plate 120, the first fixing part 514 will not face the side surface of the base plate 110 away from the lamp panel 200. This prevents the first fixing part 514 from protruding from the side plate 120 and affecting the assembly with other structural components.

[0099] Furthermore, the end of the second fixing part 522 near the base plate 110 may be higher than the end of the first fixing part 514 near the base plate 110. Since the first fixing part 514 and the second fixing part 522 are always fixed together, the second fixing part 522 can also be guaranteed not to protrude from the bottom surface of the base plate 110 if the first fixing part 514 does not protrude from the bottom surface of the base plate 110.

[0100] In some alternative embodiments, the limiting part 513 can be an elastic cantilever, that is, the limiting part 513 can rotate relative to the first support part 511 to change the angle between the limiting part 513 and the lamp panel 200. When the OD value is changed, the first support part 511 moves up or down relative to the lamp panel 200, and the limiting part 513 can adjust the angle between itself and the lamp panel 200 according to different situations, so that the limiting part 513 can always maintain abutment with the lamp panel 200.

[0101] It is particularly worth mentioning that when the OD of the display device changes from large to small, it is necessary to replace the second support part 512 or cut the second support part 512, but it is not necessary to cut the limiting part 513. The limiting part 513 can be rotated relative to the first support part 111, so that one end of the limiting part 513 is connected to the first support part 511 while the other end can abut against the lamp panel 200. This can reduce the changes to the overall structure of the first frame 510.

[0102] In some embodiments, reference Figure 11 The first frame 510 may further include a fourth support portion 515, which is connected to the side of the second support portion 512 facing the lamp panel 200. The fourth support portion 515 is located within the accommodating space and between the second support portion 512 and the limiting portion 513. That is, the orthographic projection of the fourth support portion 515 on the projection plane is located between the orthographic projection of the side plate 120 on the projection plane and the orthographic projection of the lamp panel 200 on the projection plane.

[0103] The fourth support 515 extends toward the base plate 110 to abut against the base plate 110, thereby improving the stability between the first frame 510 and the back plate 100 and helping to maintain a stable distance between the diffuser plate 300 and the lamp plate 200.

[0104] refer to Figure 12 A reinforcing rib 516 may also be provided between the fourth support portion 515 and the limiting portion 513 to improve the overall structural stability of the first frame 510. Since the included angle between the limiting portion 513 and the first support portion 511 is an obtuse angle, the distance between the end of the limiting portion 513 near the first support portion 511 and the fourth support portion 515 is small, while the distance between the end of the limiting portion 513 near the lamp panel 200 and the fourth support portion 515 is large, placing the reinforcing rib 516 in the part of the limiting portion 513 near the lamp panel 200 can more effectively improve the structural stability of the first frame 510.

[0105] When the reinforcing rib 516 is provided, the relative position between the limiting part 513 and the first support part 511 remains fixed. When the OD value is changed by cutting the second support part 512, the limiting part 513 and the fourth support part 515 also need to be cut synchronously to meet the assembly requirements between the first frame 510 and the back plate 100.

[0106] In this embodiment, as Figure 13 As shown, there can be multiple reinforcing ribs 516. These multiple reinforcing ribs 516 can be evenly and spaced along the length or width of the side plate 120, so as to further enhance the structural stability of the first frame 510.

Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
