[0033] 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. The following description of at least one exemplary embodiment is actually illustrative only and is in no way intended to limit the present utility model or its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0034] In this embodiment, as Figures 1 to 5 As shown, the display device includes: a curved screen 10, a first flat screen 20, a first locking assembly 40, and a first connecting piece 60. The curved screen 10 includes a first housing 11 and a curved display module 12 disposed on the front side of the first housing 11. The first flat screen 20 is connected to one side of the curved screen 10, and the first flat screen 20 includes a second housing 21 and a first flat display module 22 disposed on the front side of the second housing 21. The first housing 11 is spliced ​​together with the second housing 21 by the first locking assembly 40 and / or the first connecting piece 60, so that the curved display module 12 and the first flat display module 22 together form a corner display surface. The first locking assembly 40 includes a first locking rod 41 and a first locking hole 42 that locks into the first locking rod 41. The first locking rod 41 is movably disposed on one of the first housing 11 and the second housing 21, and the first locking hole 42 is disposed on the other of the first housing 11 and the second housing 21.

[0035] Thus, the first locking component 40 and the first connecting piece 60 provide diverse options for the connection method between the curved screen 10 and the first flat screen 20. In temporary events or situations requiring rapid changes in setup, the first locking component 40 allows for quick connection of the first housing 11 and the second housing 21 without the need for additional tools, shortening installation time and improving on-site work and assembly efficiency. For permanent installations or applications with high display quality requirements, the first connecting piece 60 provides an accurate and secure connection between the first housing 11 and the second housing 21, ensuring good structural stability during long-term use and preventing screen flickering or poor visual effects due to loose connections. Furthermore, the manufacturing precision of the first connecting piece 60 is easier to guarantee, resulting in higher splicing accuracy when connecting the first housing 11 and the second housing 21, making it suitable for applications with high display quality requirements. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where the connection methods between curved and flat screens cannot adapt to different user assembly needs.

[0036] In this embodiment, a first locking rod 41 is movably disposed on a first housing 11, and a first locking hole 42 is disposed on a second housing 21. The first locking rod 41 includes a rod body and a locking block disposed at one end of the rod body. The first locking rod 41 is movably and rotatably disposed on the first housing 11, so that the locking block can retract into the first housing 11 or extend out of the first housing 11 and pass through the first locking hole 42. When the first locking rod 41 rotates, it can drive the locking block to rotate, so that the locking block has a locking position that engages with the stop of the second housing 21 and an unlocking position that can be moved out of the first locking hole 42. The first locking assembly 40 also includes a return spring, disposed between the first housing 11 and the first locking rod 41. The return spring applies a force to the first locking rod 41 away from the direction of the second housing 21, so that the first locking rod 41 can remain in the position retracted into the first housing 11 when not subjected to external force.

[0037] In other embodiments, the first lock hole 42 is provided on the first housing 11, and the first lock rod 41 is movably provided on the second housing 21.

[0038] Furthermore, the display device also includes a first fastener and a second fastener. The first housing 11 is detachably connected to the first connecting piece 60 via the first fastener, and the second housing 21 is detachably connected to the first connecting piece 60 via the second fastener. This improvement enhances the stability of the connection between the first housing 11 and the second housing 21 and the ease of assembly and disassembly. The use of the first and second fasteners not only prevents accidental separation of the connecting piece from the housing during long-term use but also allows for easy disassembly when needed, facilitating on-site maintenance or component replacement, reducing maintenance time and costs, improving assembly efficiency, and ensuring the long-term stable operation of the display device.

[0039] like Figure 2As shown, a first connecting plane 111 is provided on the first housing 11. When the first housing 11 is connected to the first connecting piece 60, the first connecting plane 111 is fitted to the first connecting piece 60. This design of the first connecting plane 111 increases the contact area between the first housing 11 and the first connecting piece 60, resulting in a tighter and more secure connection. This improves the connection accuracy when the first connecting piece 60 connects the first housing 11 and the second housing 21, contributing to the flatness and consistency of the display surface of the display device. A second connecting plane 211 is provided on the second housing 21. When the second housing 21 is connected to the first connecting piece 60, the second connecting plane 211 is fitted to the first connecting piece 60. In this way, by setting the second connecting plane 211, the contact surface between the second housing 21 and the first connecting piece 60 is larger, so that the connection between the second housing 21 and the first connecting piece 60 is tighter and more secure, thereby improving the connection accuracy when the first connecting piece 60 connects the first housing 11 and the second housing 21, which helps to improve the flatness and consistency of the display surface of the display device.

[0040] In other embodiments, a first connecting plane 111 is provided on the first housing 11, and when the first housing 11 is connected to the first connecting piece 60, the first connecting plane 111 and the first connecting piece 60 are fitted together. Alternatively, a second connecting plane 211 is provided on the second housing 21, and when the second housing 21 is connected to the first connecting piece 60, the second connecting plane 211 and the first connecting piece 60 are fitted together.

[0041] like Figure 2 As shown, the first connecting piece 60 is flat. This flat design allows the first connecting piece 60 to adapt to a wider range of cabinet sizes, ensuring its versatility across different cabinet specifications. The first connecting piece 60 has multiple connecting holes 61 spaced apart. A first fastener passes through one of the connecting holes 61 corresponding to the first cabinet 11 to connect the first connecting piece 60 to the first cabinet 11; a second fastener passes through one of the connecting holes 61 corresponding to the second cabinet 21 to connect the first connecting piece 60 to the second cabinet 21. The multiple connecting holes 61 allow the first and second fasteners to pass through these holes and connect to the first cabinet 11 and the second cabinet 21 respectively. The multiple connecting holes 61 allow users to select different connecting holes 61 according to actual needs, thereby adjusting the connection position, improving the accuracy of display module splicing, and also enhancing the adaptability of the first connecting piece 60 to cabinets of different sizes.

[0042] like Figure 1 and Figure 2As shown, the display device also includes a second flat panel screen 30, a second locking component 50, and a second connecting piece 70. The first flat panel screen 20 and the second flat panel screen 30 are respectively connected to the two opposite sides of the curved screen 10. The second flat panel screen 30 includes a third housing 31 and a second flat display module 32 disposed on the front side of the third housing 31. The second locking component 50 includes a second locking rod and a second locking hole 51 that engages with the second locking rod. The second locking rod is movably disposed on one of the first housing 11 and the third housing 31, and the second locking hole 51 is disposed on the other of the first housing 11 and the third housing 31. The second connecting piece 70 connects the first housing 11 and the third housing 31. Through the above arrangement, the connection of three display surfaces can be achieved in a corner area, greatly improving the design freedom and adaptability to application scenarios. Furthermore, the arrangement of the second locking component 50 and the second connecting piece 70 provides diverse options for the connection method between the curved screen 10 and the second flat panel screen 30. In temporary events or situations requiring rapid changes in exhibition setup, the second locking component 50 enables quick connection between the first cabinet 11 and the third cabinet 31 without the need for additional tools, shortening installation time and improving on-site work efficiency and assembly efficiency. For permanent installations or applications with high display quality requirements, the second connecting piece 70 provides an accurate and secure connection between the first cabinet 11 and the third cabinet 31, ensuring good structural stability of the display device during long-term use and preventing screen flickering or poor visual effects due to loose connections. Furthermore, the manufacturing precision of the second connecting piece 70 is easier to guarantee, resulting in higher splicing accuracy when connecting the first cabinet 11 and the third cabinet 31, making it suitable for applications with high display quality requirements. Therefore, the technical solution of this application effectively solves the problem that the connection methods between curved and flat screens in related technologies cannot adapt to different user assembly needs.

[0043] like Figures 2 to 5As shown, the display device also includes a power supply box 80 disposed on the first housing 11. The power supply box 80 is detachably connected to the first housing 11 via a third fastener 90. The first housing 11 has a first threaded hole. The power supply box 80 has a mounting hole. The third fastener 90 includes an optical axis section, a nut 91, and a threaded section 92. The threaded section 92 can be threadedly engaged with the first threaded hole. The optical axis section passes through the mounting hole. The nut 91 and the threaded section 92 are located at opposite ends of the optical axis section, and the outer diameters of both the nut 91 and the threaded section 92 are larger than the diameter of the mounting hole. The power supply box 80 is detachably connected to the first housing 11 via the third fastener 90. This design makes the maintenance and disassembly of the power supply box 80 easier. The structure of the third fastener 90 allows the threaded section 92 of the third fastener 90 to connect with the first threaded hole of the first housing 11, thereby connecting the power supply box 80 to the first housing 11. The structure of the third fastener 90 ensures that when the threaded section 92 of the third fastener 90 is separated from the first threaded hole of the first housing 11, the outer diameter of both the nut 91 and the threaded section 92 is larger than the diameter of the mounting hole, and the optical shaft section passes through the mounting hole. This prevents the third fastener 90 from falling off the power box 80, reduces the steps required for collecting and storing the third fastener 90, avoids the loss of the third fastener 90, and improves maintenance and assembly efficiency.

[0044] In this embodiment, after the optical axis segment passes through the mounting hole, the nut 91 is welded to the optical axis segment. Alternatively, both ends of the optical axis segment are provided with threaded sections 92, and the screw is threadedly connected to the threaded section 92 at one end of the optical axis segment.

[0045] Furthermore, the display device also includes an elastic element disposed between the power supply box 80 and the third fastener 90. The elastic element applies a force to the third fastener 90 away from the first housing 11. By providing the elastic element, when the threaded section 92 of the third fastener 90 is separated from the first threaded hole of the first housing 11, the third fastener 90 can remain separated from the first threaded hole of the first housing 11 under the elastic force of the elastic element. This reduces interference between the third fastener 90 and the first housing 11 during the installation of the power supply box 80 onto the first housing 11, making the installation of the power supply box 80 more convenient. Moreover, when it is necessary to use the third fastener 90 to connect the first housing 11 and the power supply box 80, the user can use a tool to push against the nut 91 to overcome the elastic force of the elastic element, allowing the threaded section 92 to extend into the first threaded hole.

[0046] In this embodiment, the elastic element is a spring. The outer diameter of the threaded section 92 is larger than the outer diameter of the optical axis section, so that the end face of the threaded section 92 forms a stepped surface. One end of the spring abuts against the surface of the power supply box 80 outside the mounting hole, and the other end of the spring abuts against the stepped surface.

[0047] like Figure 4As shown, the display device also includes a support protrusion 112, which is disposed on the bottom surface of the first housing 11 and located on the side of the bottom surface of the first housing 11 closest to the curved display module 12. The support protrusion 112 raises the side of the bottom surface of the first housing 11 closest to the curved display module 12, creating a gap between the lower edge of the curved display module 12 located on the front side of the first housing 11 and the ground or placement platform. This reduces impacts to the curved display module 12 and improves its service life.

[0048] like Figure 4 As shown, the support protrusion 112 is a nut, and a threaded hole is provided on the bottom surface of the first housing 11. The nut is threaded into the threaded hole, so that the protrusion height of the nut relative to the bottom surface of the first housing 11 is adjustable. This adjustable height design of the support protrusion 112 makes the distance between the lower edge of the arc-shaped display module 12 on the front side of the first housing 11 and the ground or placement platform adjustable to adapt to ground with different flatness. Even on slightly undulating or uneven ground, the distance between the lower edge of the arc-shaped display module 12 and the ground or placement platform can be ensured by adjusting the height of the nut, further avoiding bumps and knocks to the arc-shaped display module 12 and improving the service life of the arc-shaped display module 12.

[0049] Furthermore, at least two curved screens 10 are vertically spliced ​​together, and a positioning structure is provided between two adjacent first housings 11. The positioning structure includes a positioning post 113 and a positioning hole 114 that positions and engages with the positioning post 113. The diameter of the positioning post 113 gradually decreases from the first housing 11 closest to it to the first housing 11 furthest away from it. The positioning structure improves the positional accuracy of the two curved screens 10 when vertically spliced. The gradually decreasing diameter design of the positioning post 113 allows it to be inserted more smoothly into the positioning hole 114, facilitating the assembly of the two first housings 11 and improving assembly efficiency.
