Description
Technical Field
[0001] This application relates to the field of home appliance technology, and more particularly to a display device. Background Technology
[0002] With the development of LCD technology, display devices are becoming increasingly thinner and lighter. At the same time, the structural strength requirements for display devices are also constantly increasing. How to improve the structural strength of display devices while achieving thinner and lighter designs has become a common challenge facing the industry.
[0003] In related technologies, the trend towards thinner and lighter display devices means that the thickness of the back panel is limited. To address this limited thickness, bending structures have been incorporated into the top and left / right sides of the back panel to enhance their strength. However, these bending structures only increase the strength of the top and left / right edges of the back panel in the thickness direction of the display device, thus only resisting external forces acting on the front of the display device.
[0004] However, the bottom side of a display device is susceptible to external forces not only from the front but also from the bottom. This is especially true during handling and assembly, where the bottom of the back panel is prone to deformation due to insufficient strength, leading to light leakage. Therefore, with the trend towards thinner and lighter display devices, the problem of insufficient strength on the bottom of the back panel urgently needs to be addressed. Utility Model Content
[0005] This application discloses a display device. The bottom side of the back panel of the display device has high strength, which can prevent light leakage from the bottom side of the display device due to deformation caused by stress.
[0006] To achieve the above objectives, this application discloses a display device, comprising:
[0007] Front shell;
[0008] A backplate, which is connected to the front shell;
[0009] The display panel is located between the front shell and the back plate;
[0010] A rear cover, which is connected to the front shell and is located on the side of the back panel away from the display panel;
[0011] The front shell includes:
[0012] The front shell has a display window, the display panel abuts against the front shell, and the display surface of the display panel is disposed facing the display window;
[0013] A side shell portion is provided on the front shell portion, and the side shell portion is provided around the edge of the front shell portion. The rear cover is connected to the side shell portion.
[0014] The back panel has abutment portions on all four edges, the abutment portions are connected to the side shell portion, and the abutment portions abut against the side of the display panel opposite to the front shell portion;
[0015] The abutment portion located at the bottom edge of the back plate is the first abutment portion, and the first abutment portion includes:
[0016] A first extension abuts against the side of the display panel opposite to the front shell portion;
[0017] A second extension extends from the end of the first extension in a direction away from the display panel, and the second extension is connected to the side shell portion;
[0018] A third extension extends from the end of the second extension toward the display panel;
[0019] The fourth extension extends from the end of the third extension in a direction away from the side shell portion.
[0020] The third extension extends from the end of the second extension towards the display panel, serving as a reinforcement to increase the strength of the second extension. Thus, when the side shell is subjected to external force, the second extension connected to the side shell has sufficient strength to resist deformation caused by the force. The fourth extension extends from the end of the third extension away from the side shell, serving as a reinforcement to increase the strength of the third extension. Thus, when the front shell is subjected to external force, the force is transmitted through the display panel to the first extension, which also has sufficient strength to resist deformation caused by the force. Therefore, by increasing the strength of the first and second extensions, the bottom side of the back panel has strong structural strength, preventing light leakage from the bottom side of the display device due to deformation caused by stress.
[0021] On the other hand, this application discloses a display device, comprising:
[0022] Front shell;
[0023] A backplate, which is connected to the front shell;
[0024] The display panel is located between the front shell and the back plate;
[0025] A rear cover, which is connected to the front shell and is located on the side of the back panel away from the display panel;
[0026] The front shell includes:
[0027] The front shell has a display window, the display panel abuts against the front shell, and the display surface of the display panel is disposed facing the display window;
[0028] A side shell portion is provided on the front shell portion, and the side shell portion is provided around the edge of the front shell portion. The rear cover is connected to the side shell portion.
[0029] The back panel has abutment portions on all four edges, the abutment portions are connected to the side shell portion, and the abutment portions abut against the side of the display panel opposite to the front shell portion;
[0030] The abutment portion located at the bottom edge of the back plate is the first abutment portion, and the first abutment portion includes:
[0031] A first extension abuts against the side of the display panel opposite to the front shell portion;
[0032] A second extension extends from the end of the first extension in a direction away from the display panel, and the second extension is connected to the side shell portion;
[0033] A third extension is connected to the end of the second extension and is located on one side of the second extension;
[0034] A fourth extension is connected to the end of the third extension and is located on one side of the first extension.
[0035] The third extension is connected to the end of the second extension and is located on one side of the second extension. The third extension acts as a reinforcement for the second extension, thus increasing its strength. Therefore, when the side shell is subjected to an external force F2, the second extension connected to the side shell has sufficient strength to resist deformation caused by the external force F2. The first abutment includes a fourth extension connected to the end of the third extension and is located on one side of the first extension. The fourth extension acts as a reinforcement for the first extension, thus increasing its strength. Therefore, when the front shell is subjected to an external force F1, the external force F1 is transmitted to the first extension through the display panel, and the first extension has sufficient strength to resist deformation caused by the external force F1. Therefore, by increasing the strength of the first and second extensions, the bottom side of the back panel has strong structural strength, preventing light leakage from the bottom side of the display device due to deformation caused by stress.
[0036] In some embodiments of this application, the third extension is located on the side of the second extension away from the side shell portion, and the fourth extension is located on the side of the first extension away from the display panel;
[0037] Alternatively, the third extension is located on the side of the second extension facing the side shell, and the fourth extension is located on the side of the first extension facing the display panel.
[0038] By having the third and fourth extensions located on one side of the second extension and one side of the first extension, respectively, the strength of both the second and first extensions in the thickness direction is improved. Furthermore, the third and fourth extensions can extend along one side surface of both the first and second extensions, allowing for direct molding via bending, injection molding, or other methods, thus reducing production difficulty.
[0039] In some embodiments of this application, the first extension is fixedly connected to the fourth extension in the thickness direction of the first extension;
[0040] And / or, along the thickness direction of the second extension, the second extension is fixedly connected to the third extension.
[0041] By fixing the first extension to the fourth extension, the two extensions can form a whole, resulting in high structural strength and strong resistance to torsion. Furthermore, this prevents the fourth extension from warping relative to the first extension under stress when acting as a reinforcement (i.e., creating a gap between the four extensions), which could reduce the reinforcement effect or even cause failure of the fourth extension. Similarly, by fixing the second extension to the third extension, the two extensions can form a whole, resulting in high structural strength and strong resistance to torsion. Furthermore, this prevents the third extension from warping relative to the second extension under stress when acting as a reinforcement (i.e., creating a gap between the two extensions), which could reduce the reinforcement effect or even cause failure of the third extension.
[0042] In some embodiments of this application, the first extension and the fourth extension are fixedly connected by a plurality of connecting structures along the thickness direction of the first extension, and the plurality of connecting structures are arranged at intervals along the width direction of the display device.
[0043] The first extension and the fourth extension are fixedly connected by multiple connecting structures. The connection strength between the first extension and the fourth extension is high, the overall structure is more compact, and the bottom side of the back plate has high structural strength and strong resistance to torsion.
[0044] In some embodiments of this application, the interval between two adjacent connection structures is L1, where L1 ≥ 30 mm and L1 ≤ 60 mm.
[0045] With a spacing L1 between two adjacent connecting structures of ≥30mm, the connection strength between the first extension and the fourth extension meets the design requirements, and the processing difficulty and cost of the back panel are relatively low. Alternatively, with a spacing L1 between two adjacent connecting structures of ≤60mm, the connection strength between the first extension and the fourth extension also meets the design requirements.
[0046] In some embodiments of this application, the thickness of the first extension is T, and along the thickness direction of the first extension, the first extension and the fourth extension are fixedly connected by a rivetless connection, and the outer diameter of the rivetless interlocking connection point is D, where D≥3T.
[0047] The outer diameter D of the interlocking connection point without rivets can be D≥3T. The connection strength between the first extension and the fourth extension is high, and the structural strength and torsional resistance of the bottom side of the back plate are high.
[0048] In some embodiments of this application, the extension length of the first extension is L2. Along the thickness direction of the first extension, the first extension and the fourth extension are fixedly connected by a rivetless connection, and the outer diameter of the rivetless interlocking connection point is D, where D≥0.2L2; D≤0.8L2.
[0049] For rivetless interlocking joints, the outer diameter D can be D < 0.2L², resulting in higher connection strength between the first and fourth extensions, higher structural strength on the bottom side of the backplate, and stronger torsional resistance. Conversely, for rivetless interlocking joints, the outer diameter D can be D > 0.8L², ensuring the connection strength between the first and fourth extensions meets design requirements and preventing cracking on the riveted side, resulting in higher strength at the interlocking joint.
[0050] In some embodiments of this application, the thickness of the first extension is T, and the first extension and the fourth extension are fixedly connected by a rivetless connection along the thickness direction of the first extension, and the depth of the rivetless connection is H, where H≥0.8T; H≤2T.
[0051] With a rivetless connection depth H of H≥0.8T, the connection strength between the first and fourth extensions is high, resulting in high structural strength and strong torsional resistance on the bottom side of the back plate. Alternatively, with a rivetless connection depth H≤2T, the connection strength between the first and fourth extensions meets design requirements and prevents cracking on the riveted side, resulting in high strength at the interlocking connection point.
[0052] In some embodiments of this application, the display device includes a support structure that abuts against the display panel and the first extension.
[0053] By providing a support structure that abuts against the display panel and the first extension, the first extension can be used to fix the display panel together with the front shell. Furthermore, the support structure can compensate for the height difference between the first extension and other extensions of the back plate, ensuring that the display panel is in a balanced state when fixed by the abutting force.
[0054] In some embodiments of this application, along the extending direction of the fourth extension, the distance from the side of the second extension toward the side shell to the side of the support structure away from the side shell is L3, and the distance from the side of the second extension toward the side shell to the end of the fourth extension away from the third extension is L4, where L4≥0.5L3; L4≤1.1L3.
[0055] The distance L4 from the side of the second extension toward the side shell to the end of the fourth extension away from the third extension can be L4≥0.5L3. The overlap area between the projections of the third and fourth extensions and the first extension on the first extension and the projection of the support structure on the first extension is large. When the support structure transmits the external force F1 to the first extension, a large portion of the first extension can be reinforced by the fourth extension to resist the external force F1, and the bottom side of the back plate has a strong ability to resist the external force F1. The distance L4 from the side of the second extension toward the side shell to the end of the fourth extension away from the third extension can be L4≤1.1L3. The ability of the bottom side of the back plate to resist the external force F1 already meets the design requirements, and the extension length of the fourth extension is small, which can avoid occupying space, save materials, and reduce production costs.
[0056] In some embodiments of this application, the support structure includes:
[0057] A first seal is pressed between the display panel and the first extension.
[0058] The first seal is pressed between the display panel and the first extension to achieve a seal between the back panel and the display panel, while also providing a cushioning effect. Furthermore, the first seal compensates for the height difference between the first extension and other extensions of the back panel, ensuring the display panel remains in a balanced state when fixed by the abutting force.
[0059] In some embodiments of this application, the support structure includes:
[0060] The middle frame is connected to the side shell portion and abuts between the first seal and the first extension portion.
[0061] By abutting between the middle frame and the first seal and the first extension, the overall structural strength of the display device can be improved. Furthermore, the middle frame can compensate for the height difference between the first extension and other extensions of the back panel, ensuring that the display panel remains in a balanced state when fixed by the abutting force.
[0062] In some embodiments of this application, the display device includes a second seal that is pressed between the front shell portion and the display panel.
[0063] The second seal is pressed between the front cover and the display panel to achieve a seal between them, while also providing a cushioning effect.
[0064] Compared with the prior art, this application has at least the following beneficial effects:
[0065] In this embodiment, a third extension extends from the end of the second extension toward the display panel. The third extension serves as a reinforcement for the second extension, thus increasing its strength. Therefore, when the side shell is subjected to external force, the second extension connected to the side shell has sufficient strength to resist deformation caused by the external force. A fourth extension extends from the end of the third extension toward the direction away from the side shell. The fourth extension serves as a reinforcement for the first extension, thus increasing its strength. Therefore, when the front shell is subjected to external force, the force is transmitted to the first extension via the display panel, and the first extension has sufficient strength to resist deformation caused by the external force. Therefore, by increasing the strength of the first and second extensions, the bottom side of the back panel has strong structural strength, preventing light leakage from the bottom side of the display device due to deformation caused by stress.

[0090] Before explaining the technical solution of this application, the inventive concept of this application will be explained first.
[0091] Figure 1 This is a schematic diagram of the structure of a display device 100 provided in an embodiment of this application. Figure 2 This is a structural schematic diagram of a display device 100 provided in an embodiment of this application from another perspective. Figure 3 This is an exploded structural diagram of a display device 100 provided in an embodiment of this application. For example... Figures 1 to 3 As shown, the backplate 20 is a device installed inside the display device 100 (between the front cover 10 and the rear cover 40) to protect and support the internal structure and circuitry of the display device 100.
[0092] With the increasingly thinner and lighter design of the display device 100, the back panel 20, as a crucial component ensuring the structural strength of the display device 100, urgently needs to have its structural strength improved. The external forces acting on the display device 100 mainly come from two sources: one is the external force F1 acting on the front of the display device 100, such as... Figure 2 As shown. Another is the external force F2 acting on the bottom of the display device 100, such as... Figure 1 As shown.
[0093] Since the top and left and right sides of the back plate 20 are usually only subjected to the external force F1 from the front of the display device 100, a bending structure has been provided on the top and left and right edges of the back plate 20 to increase the strength of the top and left and right edges of the back plate 20, thereby resisting the deformation of the back plate 20 on the top and left and right edges along the direction of the external force F1 caused by the external force F1.
[0094] However, the bottom side of the back panel 20 is usually subjected to an external force F1 from the front of the display device 100 and an external force F2 from the bottom of the display device 100. This means that improving the structural strength of the bottom side of the back panel 20 requires consideration of forces from multiple directions, making the improvement more difficult.
[0095] The external force F2 acting on the bottom of the display device 100 occurs not only during the handling of the display device 100, but also during the assembly of the display device 100. This is because the back plate 20 and the bottom of the front shell 10 of the display device 100 need to be fixedly connected by bolts or other means during assembly. At this time, the bottom of the front shell 10 exerts a reaction force F2 on the back plate 20.
[0096] In summary, the display device 100 in the related art suffers from the problem that the bottom side of the back plate 20 is prone to deformation due to insufficient strength, resulting in light leakage from the bottom side of the display device 100. Therefore, this application provides a display device 100 to solve the above-mentioned problem.
[0097] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0098] In some embodiments, such as Figures 1 to 3 As shown, the display device 100 includes a front cover 10.
[0099] In some embodiments, the display device 100 includes a back plate 20, which is connected to the front housing 10.
[0100] The back plate 20 is connected to the front shell 10 to achieve fixed installation. Both sides of the back plate 20 facing the front shell 10 and away from the front shell 10 can be used to support the internal structure and circuitry of the display device 100. At the same time, the back plate 20 can also improve the overall strength of the display device 100 and withstand the external forces acting on the display device 100.
[0101] In some embodiments, the display device 100 includes a display panel 30 located between the front housing 10 and the back panel 20.
[0102] Images are displayed via display panel 30. Display panel 30 can be a liquid crystal panel, specifically including TN (Twisted Nematic) panels, IPS (In-Plane Switching) panels, VA (Vertical Alignment) panels, and MVA (Multi-Domain Vertical Alignment) panels. Of course, other types of panels can also be used, such as OLED (Organic Light-Emitting Diode) panels, Mini / micro LED panels, etc., all of which are applicable to the above solutions; this embodiment does not specifically limit this.
[0103] In some embodiments, the display device 100 includes a rear cover 40, which is connected to the front housing 10 and is located on the side of the back panel 20 away from the display panel 30.
[0104] The rear cover 40 is connected to the front shell 10 to cover the display device 100, and the mounting space formed between the rear cover 40 and the front shell 10 can be used to accommodate the internal structure and circuit of the display device 100, and to protect the internal structure.
[0105] In some embodiments, combined with Figure 4 As shown, the front shell 10 includes a front shell portion 11, which has a display window 11a. The display panel 30 abuts against the front shell portion 11, and the display surface of the display panel 30 is disposed facing the display window 11a.
[0106] The front cover portion 11 abuts against the back cover portion 11, and the front cover portion 11 can fix the display panel 30 together with the back plate 20. Furthermore, the front cover portion 11 can block the non-display area of the display panel 30, and since the display surface of the display panel 30 faces the display window 11a, the display area of the display panel 30 can be displayed through the display window 11a.
[0107] In some embodiments, the front shell 10 includes a side shell portion 12, which is disposed on the front shell portion 11 and is disposed around the edge of the front shell portion 11. The rear cover 40 is closed and connected to the side shell portion 12.
[0108] The side shell 12 is provided around the edge of the front shell 11, thus wrapping around and protecting the display panel 30 from the circumferential direction. Furthermore, the side shell 12 is connected to the rear cover 40, creating a certain distance between the rear cover 40 and the front shell 11, thereby forming an installation space together with the front shell 10. For example, the back plate 20 located in the installation space can be fixedly connected to the side shell 12 for assembly.
[0109] In some embodiments, such as Figure 5 and Figure 6 As shown, the back panel 20 has abutment portions 21 on all four edges. The abutment portions 21 are connected to the side shell portion 12 and abut against the side of the display panel 30 away from the front shell portion 11.
[0110] The back plate 20 abuts against the side of the display panel 30 away from the front shell 11 through the abutting part 21 of the four edges. The display panel 30 can be stably fixed between the back plate 20 and the front shell 11, and the force on the display panel 30 is uniform, which can avoid damage caused by uneven force on the display panel 30.
[0111] In some embodiments, the abutment portion 21 located at the bottom edge of the back plate 20 is the first abutment portion.
[0112] The bottom side refers to the lower side of the display device 100 along its height direction when in use, that is, the side of the display device 100 closest to the ground. The side relatively farther from the ground is the top side, and the two sides connected to the bottom side and the top side are the left and right sides of the display device 100.
[0113] In some embodiments, combined with Figure 7 As shown, the first abutting portion includes a first extension portion 211, which abuts against the side of the display panel 30 away from the front shell portion 11.
[0114] The first extension 211 abuts against the side of the display panel 30 away from the front shell 11, and the first extension 211 and the front shell 11 can cooperate to fix the display panel 30.
[0115] In some embodiments, the first abutting portion includes a second extension 212, which extends from the end of the first extension 211 in a direction away from the display panel 30, and the second extension 212 is connected to the side shell portion 12.
[0116] By connecting the second extension 212 to the side shell 12, a fixed connection between the front shell and the back shell 10 can be achieved. Furthermore, the second extension 212 extends away from the display panel 30, thus avoiding the problem of increased design difficulty caused by the second extension 212 needing to avoid mutual avoidance with the display panel 30, circuit wiring, and other structures located between the back plate 20 and the front shell 11 during its extension.
[0117] In some embodiments, the first abutment portion includes a third extension portion 213, which extends from the end of the second extension portion 212 toward the display panel 30.
[0118] By extending from the end of the second extension 212 toward the display panel 30 via the third extension 213, the third extension 213 can serve as a reinforcement for the second extension 212, thereby increasing the strength of the second extension 212. Thus, when the side shell 12 is subjected to an external force F2, the second extension 212 connected to the side shell 12 has sufficient strength to resist the deformation caused by the external force F2.
[0119] In some embodiments, the first abutting portion includes a fourth extension 214, which extends from the end of the third extension 213 in a direction away from the side shell portion 12.
[0120] The fourth extension 214 extends from the end of the third extension 213 in a direction away from the side shell 12. The fourth extension 214 can serve as a reinforcement for the first extension 211, thereby increasing the strength of the third extension 213. Thus, when the face shell 11 is subjected to an external force F1, the external force F1 is transmitted to the first extension 211 through the display panel 30. The first extension 211 has sufficient strength to resist the deformation caused by the external force F1.
[0121] It can be understood that by increasing the strength of the first extension 211 and the second extension 212, the bottom side of the back plate 20 has a strong structural strength, which can prevent the bottom side of the back plate 20 from deforming under force and causing light leakage on the bottom side of the display device 100.
[0122] In some embodiments, the first abutment portion includes a third extension portion 213, which is connected to the end of the second extension portion 212 and is located on one side of the second extension portion 212.
[0123] The third extension 213 is connected to the end of the second extension 212 and is located on one side of the second extension 212. The third extension 213 can serve as a reinforcement for the second extension 212, thereby increasing the strength of the second extension 212. Thus, when the side shell 12 is subjected to an external force F2, the second extension 212 connected to the side shell 12 has sufficient strength to resist the deformation caused by the external force F2.
[0124] In some embodiments, the first abutting portion includes a fourth extension 214 connected to the end of the third extension 213, and the fourth extension 214 is located on one side of the first extension 211.
[0125] The first abutment portion includes a fourth extension portion 214 connected to the end of the third extension portion 213, and the fourth extension portion 214 is located on one side of the first extension portion 211. The fourth extension portion 214 can serve as a reinforcement for the first extension portion 211, thereby increasing the strength of the third extension portion 213. Thus, when the faceplate portion 11 is subjected to an external force F1, the external force F1 is transmitted to the first extension portion 211 through the display panel 30. The first extension portion 211 has sufficient strength to resist the deformation caused by the external force F1.
[0126] In some embodiments, the third extension 213 is located on the side of the second extension 212 facing the side shell 12, and the fourth extension 214 is located on the side of the first extension 211 facing the display panel 30.
[0127] The third extension 213 is located on the side of the second extension 212 facing the side shell 12. The overall thickness of the second extension 212 and the third extension 213 is relatively large, and the third extension 213 can serve as a reinforcing member for the second extension 212 on the side of the second extension 212 facing the side shell 12, thereby improving the strength of the second extension 212 in the thickness direction. Similarly, the fourth extension 214 is located on the side of the first extension 211 facing the display panel 30. The overall thickness of the first extension 211 and the fourth extension 214 is relatively large, and the fourth extension 214 can serve as a reinforcing member for the first extension 211 on the side of the first extension 211 facing the display panel 30, thereby improving the strength of the first extension 211 in the thickness direction.
[0128] Furthermore, with this design, the third extension 213 and the fourth extension 214 can extend along the outer surface of the first extension 211 and the second extension 212 as a whole, and can be directly formed by bending, injection molding and other methods, which reduces the difficulty of production.
[0129] The first extension 211 and the second extension 212 are roughly L-shaped. The outer surface refers to the surface on the side where the 270° outer angle of the L-shape is located. The surface opposite to the outer surface can be called the inner surface, which is the surface on the side where the 90° inner angle of the L-shape is located.
[0130] At this time, since the third extension 213 and the fourth extension 214 are located on the outer surface of the whole of the first extension 211 and the second extension 212, the third extension 213 can be connected to the side shell 12, and the fourth extension 214 can be abutted against the display panel 30.
[0131] In some embodiments, the third extension 213 is located on the side of the second extension 212 away from the side shell 12, and the fourth extension 214 is located on the side of the first extension 211 away from the display panel 30.
[0132] The third extension 213 is located on the side of the second extension 212 away from the side shell 12. The overall thickness of the second extension 212 and the third extension 213 is relatively large, and the third extension 213 can serve as a reinforcement for the second extension 212 on the side away from the side shell 12, thus improving the strength of the second extension 212 in the thickness direction. Similarly, the fourth extension 214 is located on the side of the first extension 211 away from the display panel 30. The overall thickness of the first extension 211 and the fourth extension 214 is relatively large, and the fourth extension 214 can serve as a reinforcement for the first extension 211 on the side of the first extension 211 facing the display panel 30, thus improving the strength of the first extension 211 in the thickness direction.
[0133] Furthermore, with this design, the third extension 213 and the fourth extension 214 can extend along the inner surface of the entire first extension 211 and the second extension 212, and can be directly formed by bending, injection molding, etc., which reduces the difficulty of production.
[0134] Furthermore, the third extension 213 and the fourth extension 214 extend along the inner surface of the entire first extension 211 and the second extension 212, without changing the relative positions of the first extension 211 and the second extension 212 with the display panel 30 and the side shell 12. That is, the first extension 211 is grounded to the display panel, the second extension 212 is connected to the side shell 12, and the third extension 213 and the fourth extension 214 are arranged in the space on one side of the 90° inner angle of the L-shape, which does not affect the thickness and height of the display device 100, thus maintaining the slim design of the display device 100.
[0135] In some embodiments, the third extension 213 and the fourth extension 214 may extend along different side surfaces of the first extension 211 and the second extension 212.
[0136] For example, such as Figure 8 As shown, the third extension 213 extends along the inner surface of the second extension 212, and the fourth extension 214 extends along the outer surface of the first extension 211.
[0137] For example, the third extension 213 extends along the outer surface of the second extension 212, and the fourth extension 214 extends along the inner surface of the first extension 211.
[0138] Thus, the third extension 213 and the fourth extension 214 need to be connected by a transition portion, and the transition portion passes through the through hole in the first extension 211 or the second extension 212. This allows the third extension 213, located on one side surface of the first extension 211 and the second extension 212, to extend continuously to the fourth extension 214, located on the other side surface of the first extension 211 and the second extension 212.
[0139] In some embodiments, the second extension 212 is fixedly connected to the third extension 213 along the thickness direction of the second extension 212.
[0140] By fixing the second extension 212 and the third extension 213 together, the second extension 212 and the third extension 213 can form an integral whole, resulting in high structural strength and strong resistance to torsion. Furthermore, this prevents the third extension 213 from warping relative to the second extension 212 under stress when acting as a reinforcement (i.e., preventing a gap between the third extension 213 and the second extension 212), which could reduce the reinforcing effect of the third extension 213 or even cause it to fail.
[0141] In some embodiments, the first extension 211 and the fourth extension 214 are fixedly connected along the thickness direction of the first extension 211.
[0142] By fixing the first extension 211 and the fourth extension 214 together, the first extension 211 and the fourth extension 214 can form a whole, resulting in high structural strength and strong resistance to torsion. Furthermore, this prevents the fourth extension 214 from warping relative to the first extension 211 under stress when acting as a reinforcement (i.e., preventing a gap between the fourth extension 214 and the first extension 211), which could reduce the reinforcing effect of the fourth extension 214 or even cause it to fail.
[0143] The fixed connection methods of the first extension 211 and the fourth extension 214, and the fixed connection methods of the second extension 212 and the third extension 213, can be welding, riveting, or rivetless riveting, etc., and this embodiment does not specifically limit them. The fixed connection method of rivetless riveting results in a firm and reliable connection point, no stress concentration, good surface quality, and a simple process with high production efficiency.
[0144] In some embodiments, such as Figure 9 As shown, along the thickness direction of the first extension 211, the first extension 211 and the fourth extension 214 are fixedly connected by a plurality of connecting structures a, and the plurality of connecting structures a are arranged at intervals along the width direction of the display device 100.
[0145] The first extension 211 and the fourth extension 214 are fixedly connected by multiple connection structures a. The connection strength between the first extension 211 and the fourth extension 214 is high, the overall structure is more compact, and the bottom side of the back plate 20 has high structural strength and strong resistance to torsion.
[0146] In some embodiments, the spacing between two adjacent connection structures a is L1, where L1 ≥ 30 mm.
[0147] If the distance L1 between two adjacent connecting structures a is less than 30mm, then with a fixed dimension of the back panel 20 along the width direction of the display device 100, the number of connecting structures a will be large and dense. The connection strength between the first extension 211 and the fourth extension 214 will far exceed the design requirements, thus increasing the processing difficulty and cost of the back panel 20. Therefore, the distance L1 between two adjacent connecting structures a can be L1 ≥ 30mm. The connection strength between the first extension 211 and the fourth extension 214 can meet the design requirements, and the processing difficulty and cost of the back panel 20 will be lower.
[0148] In some embodiments, the spacing between two adjacent connection structures a is L1, where L1 ≤ 60 mm.
[0149] If the distance L1 between two adjacent connecting structures a is greater than 60mm, then with a fixed dimension of the backplate 20 along the width direction of the display device 100, the number of connecting structures a is small and sparse, and the connection strength between the first extension 211 and the fourth extension 214 cannot meet the design requirements. Therefore, the distance L1 between two adjacent connecting structures a can be L1≤60mm, and the connection strength between the first extension 211 and the fourth extension 214 can meet the design requirements.
[0150] Therefore, the interval L1 between two adjacent connecting structures a can be 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, etc., and this embodiment does not make a specific limitation on this.
[0151] In some embodiments, such as Figure 7 As shown, the thickness of the first extension 211 is T. Along the thickness direction of the first extension 211, the first extension 211 and the fourth extension 214 are fixedly connected by a rivetless connection, and the outer diameter of the rivetless interlocking connection point is D, where D≥3T.
[0152] If the outer diameter D of the rivetless interlocking connection point is less than 3T, the size of the interlocking connection point is small, the connection strength between the first extension 211 and the fourth extension 214 is low, and the structural strength and torsional resistance of the bottom side of the back plate 20 are low. Therefore, the outer diameter D of the rivetless interlocking connection point can be D≥3T, the connection strength between the first extension 211 and the fourth extension 214 is high, and the structural strength and torsional resistance of the bottom side of the back plate 20 are high.
[0153] Furthermore, the outer diameter D of the rivetless interlocking connection point can be 3T, 3.5T, 4T, 4.5T, 5T, 5.5T, 6T, etc., and this embodiment does not specifically limit this. When the area of the overlapping surface of the first extension 211 and the second extension 212 is sufficiently large, the outer diameter D of the rivetless interlocking connection point should be taken to a larger value as possible.
[0154] In some embodiments, the extension length of the first extension 211 is L2. Along the thickness direction of the first extension 211, the first extension 211 and the fourth extension 214 are fixedly connected by a rivetless connection, and the outer diameter of the rivetless interlocking connection point is D, where D≥0.2L2.
[0155] If the outer diameter D of the rivetless interlocking connection point is less than 0.2L², the size of the interlocking connection point is small, the connection strength between the first extension 211 and the fourth extension 214 is low, and the structural strength and torsional resistance of the bottom side of the back plate 20 are low. Therefore, the outer diameter D of the rivetless interlocking connection point can be D < 0.2L², the connection strength between the first extension 211 and the fourth extension 214 is high, and the structural strength and torsional resistance of the bottom side of the back plate 20 are high.
[0156] In some embodiments, the extension length of the first extension 211 is L2. Along the thickness direction of the first extension 211, the first extension 211 and the fourth extension 214 are fixedly connected by a rivetless connection, and the outer diameter of the rivetless interlocking connection point is D, where D≤0.8L2.
[0157] If the outer diameter D of the rivetless interlocking connection point is greater than 0.8L², then while the connection strength between the first extension 211 and the fourth extension 214 meets the design requirements, the size of the interlocking connection point is relatively large, which can easily lead to cracking on the riveted side and reduce the strength of the interlocking connection point. Therefore, the outer diameter D of the rivetless interlocking connection point can be greater than 0.8L². The connection strength between the first extension 211 and the fourth extension 214 can meet the design requirements and avoid cracking on the riveted side, resulting in higher strength of the interlocking connection point.
[0158] Therefore, the outer diameter D of the rivetless interlocking connection point can be 0.2L2, 0.3L2, 0.4L2, 0.5L2, 0.6L2, 0.7L2, 0.8L2, etc., and this embodiment does not make a specific limitation on it.
[0159] In some embodiments, the thickness of the first extension 211 is T, and the first extension 211 and the fourth extension 214 are fixedly connected by a rivetless connection along the thickness direction of the first extension 211, and the depth of the rivetless connection is H, where H≥0.8T.
[0160] If the depth H of the rivetless joint is less than 0.8T, the rivetless joint depth is relatively small, the connection strength between the first extension 211 and the fourth extension 214 is low, and the structural strength and torsional resistance of the bottom side of the back plate 20 are low. Therefore, the depth H of the rivetless joint can be H≥0.8T, the connection strength between the first extension 211 and the fourth extension 214 is high, and the structural strength and torsional resistance of the bottom side of the back plate 20 are high.
[0161] In some embodiments, the thickness of the first extension 211 is T, and the first extension 211 and the fourth extension 214 are fixedly connected by a rivetless connection along the thickness direction of the first extension 211, and the depth of the rivetless connection is H, where H≤2T.
[0162] If the depth H of the rivetless connection is greater than 2T, then while the connection strength between the first extension 211 and the fourth extension 214 meets the design requirements, a large rivetless connection depth can easily lead to cracking on the riveted side, reducing the strength of the interlocking connection point. Therefore, the depth H of the rivetless connection can be H≤2T. This ensures that the connection strength between the first extension 211 and the fourth extension 214 meets the design requirements, avoids cracking on the riveted side, and results in higher strength at the interlocking connection point.
[0163] Therefore, the depth H of the rivetless joint can be 0.8T, T, 1.2T, 1.4T, 1.6T, 1.8T, 2T, etc., and this embodiment does not make a specific limitation on it.
[0164] In some embodiments, such as Figure 3 and Figure 7 As shown, the display device 100 includes a support structure 50, which abuts between the display panel 30 and the first extension 211.
[0165] By providing a support structure 50, which abuts against the display panel 30 and the first extension 211, the first extension 211 can be used to fix the display panel 30 together with the front shell portion 11 with the help of the support structure 50. Furthermore, the support structure 50 can compensate for the height difference between the first extension 211 and other extensions of the back plate 20, ensuring that the display panel 30 is in a balanced state when fixed by the abutting force.
[0166] In some embodiments, such as Figure 7 As shown, along the extension direction of the fourth extension 214, the distance from the side of the second extension 212 toward the side shell 12 to the side of the support structure 50 away from the side shell 12 is L3, and the distance from the side of the second extension 212 toward the side shell 12 to the end of the fourth extension 214 away from the third extension 213 is L4, where L4 ≥ 0.5L3.
[0167] If the distance L4 from the side of the second extension 212 toward the shell 12 to the end of the fourth extension 214 away from the third extension 213 is less than 0.5L3, then along the thickness direction of the first extension 211, the size of the overlapping portion of the third extension 213 and the fourth extension 214 with the first extension 211 is small, the overlapping area of the projection of the third extension 213 and the fourth extension 214 with the first extension 211 on the first extension 211 and the projection of the support structure 50 on the first extension 211 is small, when the support structure 50 transmits the external force F1 to the first extension 211, a large part of the first extension 211 cannot be reinforced by the fourth extension 214 to resist the external force F1, and the bottom side of the back plate 20 has a weak ability to resist the external force F1. Therefore, the distance L4 from the side of the second extension 212 facing the side shell 12 to the end of the fourth extension 214 away from the third extension 213 can be L4≥0.5L3. The overlapping area of the projection of the third extension 213 and the fourth extension 214 and the projection of the first extension 211 on the first extension 211 and the projection of the support structure 50 on the first extension 211 is large. When the support structure 50 transmits the external force F1 to the first extension 211, a large part of the first extension 211 can be reinforced by the fourth extension 214 to resist the external force F1. The bottom side of the back plate 20 has a strong ability to resist the external force F1.
[0168] In some embodiments, along the extending direction of the fourth extension 214, the distance from the side of the second extension 212 toward the side shell 12 to the side of the support structure 50 away from the side shell 12 is L3, and the distance from the side of the second extension 212 toward the side shell 12 to the end of the fourth extension 214 away from the third extension 213 is L4, where L4 ≤ 1.1L3.
[0169] If the distance L4 from the side of the second extension 212 toward the shell 12 to the end of the fourth extension 214 away from the third extension 213 is greater than 1.1.L3, then along the thickness direction of the first extension 211, the size of the overlapping portion of the third extension 213 and the fourth extension 214 with the first extension 211 is large, and the projection of the third extension 213 and the fourth extension 214 with the first extension 211 on the first extension 211 is completely coincident with the projection of the support structure 50 on the first extension 211. At this time, the ability of the bottom side of the back plate 20 to resist the external force F1 has met the design requirements. The large extension length of the fourth extension 214 will cause problems such as space occupation, material waste, and high production cost. Therefore, the distance L4 from the side of the second extension 212 facing the side shell 12 to the end of the fourth extension 214 away from the third extension 213 can be L4≤1.1L3. The ability of the bottom side of the back plate 20 to resist external force F1 has met the design requirements. Moreover, the extension length of the fourth extension 214 is small, which can avoid occupying space and save materials and reduce production costs.
[0170] Therefore, the distance L4 from the side of the second extension 212 toward the side shell 12 to the end of the fourth extension 214 away from the third extension 213 can be 0.5L3, 0.6L3, 0.7L3, 0.8L3, 0.9L3, L3, 1.1L3, etc., and this embodiment does not specifically limit it.
[0171] In some embodiments, such as Figure 3 and Figure 7 As shown, the support structure 50 includes a first seal 51, which is pressed between the display panel 30 and the first extension 211.
[0172] The first sealing member 51 is pressed between the display panel 30 and the first extension 211, thereby achieving a seal between the back plate 20 and the display panel 30, and also providing a cushioning effect. Furthermore, the first sealing member 51 can compensate for the height difference between the first extension 211 and other extensions of the back plate 20, so that the display panel 30 is in a balanced state when fixed by the abutting force.
[0173] In some embodiments, the support structure 50 includes a middle frame 52 connected to the side shell portion 12, and the middle frame 52 abuts between the first seal 51 and the first extension portion 211.
[0174] By abutting between the first seal 51 and the first extension 211, the overall structural strength of the display device 100 can be improved. Furthermore, the middle frame 52 can compensate for the height difference between the first extension 211 and other extensions of the back plate 20, so that the display panel 30 is in a balanced state when fixed by the abutting force.
[0175] The middle frame 52 can be a plastic frame, which has a cushioning effect. In addition, the plastic frame can act as a barrier to prevent harmful substances such as dust and moisture from entering between the display panel 30 and the back panel 20.
[0176] In some embodiments, the display device 100 includes a second seal 60, which is pressed between the front shell portion 11 and the display panel 30.
[0177] The second sealing element 60 is pressed between the front cover 11 and the display panel 30 to achieve a seal between the front cover 11 and the display panel 30, while also providing a buffering effect.
[0178] The above provides a detailed description of a display device disclosed in the embodiments of this application. This document uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand a display device and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
