[0034] In this embodiment, Figure 4 As shown, the two side surfaces of the connecting through hole 54 are arc-shaped surfaces, which is equivalent to the connecting through hole 54 being a transition section, making it easier and more labor-saving for users to install.

[0035] In this embodiment, Figure 4-5 As shown, preferably, there are three clamping holes 511, three openings 512 and three clamping posts 53. When the foot pad has a certain length, the stability of supporting the display screen is higher.

[0036] In this embodiment, Figure 5-6 As shown, the shell 52 includes an upper mounting plate 522, a lower mounting plate 523 and a side connecting plate 524, and the two ends of the side connecting plate 524 are respectively connected to one end of the upper mounting plate 522 and one end of the lower mounting plate 523, and the upper mounting plate 522, the lower mounting plate 523 and the side connecting plate 524 are connected to form a U-shaped mounting groove 521, and the shape of the side connecting plate 524 is set to an outward arc shape, which not only reduces the wear rate of the corners of the shell 52, but also prevents the corners from scratching the user.

[0037] In this embodiment, Figure 4 As shown, the front and back surfaces of the bracket 4 at the foot pad mounting position 51 are provided with inwardly concave notches 41. When the foot pad 5 is installed at the foot pad mounting position 51, the upper mounting plate 522 and the lower mounting plate 523 are respectively located in the two notches 41 on the front and back surfaces of the bracket 4, and the outer side surface of the upper mounting plate 522 is in the same horizontal plane as the upper surface of the bracket 4, and the outer side surface of the lower mounting plate 523 is in the same horizontal plane as the lower surface of the bracket 4, so that the foot pad is more integrated with the bracket, making the bracket beautiful and reducing the wear rate of the foot pad.

[0038] In this embodiment, there are two foot pad mounting positions 51 , and the two foot pad mounting positions 51 are arranged on both sides of one end of the bracket 4 away from the first connecting edge 101 or the second connecting edge 201 , making the bracket more stable and reducing the wear rate of the bracket.

[0039] In this embodiment, Figure 2-3 As shown, the shape of the bracket 4 is U-shaped, and a cover plate 6 is protruding from the back of the second display screen 2. The two ends of the U-shaped bracket can be rotatably connected to both sides of the cover plate 6. When the U-shaped bracket is not unfolded, the U-shaped bracket is sleeved on the outside of the cover plate 6 and abuts against the plane on the back of the second display screen 2. The U-shaped support has strong stability.

[0040] The dual-screen display further comprises a hinge device 3, such as Figure 2As shown, the first display screen 1 is electrically connected to the second display screen 2, and the first connecting edge 101 of the first display screen 1 is connected to the second connecting edge 201 of the second display screen 2 via a hinge device 3, and the first display screen 1 can be rotated so that the front of the first display screen 1 is in contact with the front of the second display screen 2, and the back of the first display screen 1 is in contact with the back of the second display screen 2, so that the screen of the first display screen and the screen of the second display screen can be in different viewing surfaces, allowing multiple people to view the screen from multiple sides, thereby expanding the function of the dual-screen display, and the dual-screen display can be folded and fitted together for easy carrying by users, thereby improving the user experience.

[0041] In this embodiment, when the first display screen 1 rotates, the first display screen 1 drives the second display screen 2 to rotate relative to the first display screen 1 through the hinge device 3. The two display screens of the traditional dual display have no linkage effect, which is inconvenient to use. Therefore, in this embodiment, the first display screen 1 and the second display screen are linked and can rotate in relative directions. When in use, there is no need to press one display screen and then rotate the other display screen, which is convenient for users.

[0042] In this embodiment, Figure 7 As shown, the hinge device 3 includes a first connecting component 31, a second connecting component 32 and a third connecting component 33.

Through the connection and rotation between the gears, the first display screen drives the second display screen through the transmission between the gears. The structure is simple and the transmission linkage is high. The bevel gears have good meshing performance and large overlap. The meshing time of the bevel gears is long and the contact area is large, which reduces stress, makes the window opening more stable, and improves economic efficiency. The bevel gears have a relatively compact structure and also have a relatively ideal deceleration effect.

[0044] In this embodiment, Figure 7-8 As shown, the hinge device 3 also includes a fourth connecting member 34. The third bevel gear 331 is provided with a central shaft 332 integrally formed with the third bevel gear 331. Both ends of the central shaft 332 pass through both sides of the third bevel gear 331. Both ends of the fourth connecting member 34 are connected to the first connecting member 312 and the second connecting member 322. The middle part of the fourth connecting member 34 is clamped on the central shaft 332. The fourth connecting member 34 is mainly used to fix the third bevel gear to prevent the third bevel gear from being unstable during rotation, resulting in a poor user experience.

[0045] like Figure 10 As shown, the fourth connecting member 34 includes a first connecting plate 341, a second connecting plate 342, a third connecting plate 343 and a fourth connecting plate 344. The left and right ends of the first connecting plate 341 are connected to the first connecting member 312 and the second connecting member 322, and are located at the first end of the first helical gear 311 and the first end of the second helical gear 321. The left and right ends of the second connecting plate 342 are connected to the first connecting member 312 and the second connecting member 322, and are located at the second end of the first helical gear 311 and the second end of the second helical gear 321. The third connecting plate 343 and the fourth connecting plate 344 are arranged on both sides of the third helical gear 331. Both ends of the third connecting plate 343 and both ends of the fourth connecting plate 344 are fixedly connected to the first connecting plate 341 and the second connecting plate 342. The third connecting plate 343 and the fourth connecting plate 344 are both provided with mounting holes 3440, and the mounting holes 3440 are sleeved on the central shaft 332.

[0046] In this embodiment, Figure 10 When the first and second connecting portions 341 and 342 are engaged, the first and second connecting portions 3443 and 3444 are engaged, and the first and second connecting portions 3443 and 3444 are engaged.
