[0038] At least one embodiment of this application is a connection structure for a display screen, the specific structure of which is as follows: Figures 1-9 As shown. Figure 1 As shown, the connecting structure is used to connect the display screen 10 and the support member 20. The connecting structure includes a boss 31 and a groove 41. The cross-sectional shape of the boss 31 has fourth-order rotational symmetry, which means that the shape coincides with itself four times in one rotation, that is, it coincides with itself every 90 degrees. Figure 1 As shown, a boss 31 is located on the side of the support member 20 facing the display screen 10, and a groove 41 is located on the side of the display screen 10 facing the support member 20. The cross-sectional shape and size of the groove 41 are the same as those of the boss 31. The boss 31 is inserted into the groove 41 and is detachably fixed to the groove 41 by magnetic attraction and / or snap-fit. When the boss 31 is inserted into the groove 41, the outer wall of the boss 31 is completely fitted with the inner wall of the groove 41, thus preventing the boss 31 and the groove 41 from rotating relative to each other, and preventing the display screen 10 from automatically rotating relative to the support member 20. When it is necessary to adjust the orientation of the display screen 10, the display screen 10 is first removed from the support member 20, the display screen 10 is rotated 90 degrees, and then the boss 31 is inserted into the groove 41 for fixation.

[0039] At least one embodiment employs a detachably connected boss 31 and groove 41 to connect the display screen 10 and the support member 20. The boss 31 can be rotated 90 degrees to coincide with itself, and the groove 41 has the same shape and size as the boss 31. The boss 31, even after rotating 90 degrees, can be inserted into the groove 41 for fixation (or the groove 41 can rotate 90 degrees without the boss 31 remaining stationary). Figure 2 The display screen 10 shown is horizontally mounted with the support 20, or as shown in the figure. Figure 3 The display screen 10 shown is vertically mounted with the support member 20, which means that the display screen 10 can be used vertically or horizontally as needed, meeting the relevant needs of users and improving ease of use.

[0040] In some embodiments, such as Figure 1As shown, the cross-sectional shape of the boss 31 is square, and the cross-sectional shape of the groove 41 is also correspondingly square. In some other embodiments, the cross-sectional shape of the boss is a regular octagon or a regular cross. Furthermore, in some embodiments, such as... Figure 1 As shown, four circular buffer pads 411 are provided on the bottom surface of the groove 41 to prevent scratches caused by direct contact between the boss 31 and the bottom surface of the groove 41. Annular buffer pads 201 are also provided around the boss 31 to prevent scratches caused by direct contact between the support member 20 and the outer periphery of the groove 41.

[0041] In some embodiments, such as Figure 1 As shown, the boss 31 has an outwardly extending latching head 51, and the groove 41 has a rectangular latching hole 42 corresponding to the latching head 51. The latching head 51 is inserted into the latching hole 42 to form a latching connection. Specifically, there are two latching heads 51 arranged side by side, and there are two sets of latching holes 42, with each set consisting of two latching holes 42. Figure 1 The two locking holes 42 at the top and bottom form one group, and the two locking holes 42 on the left and right form another group. Each group of two locking holes 42 corresponds one-to-one with the locking head 51. After rotating 90 degrees around the center 43 between the locking holes 42 in each group, it coincides with the locking holes 42 in the other group. When the boss 31 and the groove 41 rotate 90 degrees relative to each other, the locking head 51 corresponds with the locking holes 42 in the other group, and the locking head 51 is inserted into the locking hole 42 to form a locking and fixing.

[0042] In some embodiments, combined with Figure 1 and Figure 5 As shown, a first positioning ring 32 is provided around the periphery of the latch head 51, and a first annular groove 44 is provided around the periphery of the latch hole 42, with the first positioning ring 32 inserted into the first annular groove 44. Furthermore, a second positioning ring 45 is provided around the periphery of the first annular groove 44, and a second annular groove 33 is provided around the periphery of the first positioning ring 32, with the second positioning ring 45 inserted into the second annular groove 33. The cooperation between the first positioning ring 32 and the first annular groove 44, and the cooperation between the second positioning ring 45 and the second annular groove 33, serves to assist in positioning, while also improving sealing and reducing the entry of dust and impurities from the latch hole 42.

[0043] In some embodiments, such as Figure 1 As shown, the outer end face of the first positioning ring 32 has four recesses 321, and the first annular groove 44 has positioning protrusions 441 corresponding to the recesses 321. The positioning protrusions 441 are placed in the recesses 321 to assist in positioning and alignment. Specifically, every two adjacent parallel positioning protrusions 441 are placed in one recess 321.

[0044] In some embodiments, combined with Figure 5 and Figure 7As shown, two side-by-side latching heads 51 are mounted on a slider 50. The slider 50 has a degree of freedom to move linearly relative to the boss 31, while the latching heads 51 move synchronously with the slider 50 and pass through the through hole 311 of the boss 31. During the linear movement of the slider 50 relative to the boss 31, when the slider 50 is in at least one of the positions (e.g., ... Figure 5 (When the slider 50 is in its initial position), the buckle head 51 engages with the buckle hole 42 (e.g., when the slider 50 is in its initial position). Figure 5 The solid line indicates the position of the latch head 51. When the slider 50 moves linearly to at least one of these positions, the latch head 51 disengages from the latch hole 42 (as shown in the diagram). Figure 5 (The position of the buckle head 51' shown by the dotted line) If the display screen 10 is separated from the support 20 at this time, the buckle head 51 will be pulled out from the buckle hole 42.

[0045] In some embodiments, such as Figure 5 As shown, chamfers 421 are provided on both sides of the opening of the locking hole 42. This helps to reduce the resistance of the locking head 51 entering the locking hole 42 and also makes way for the linearly moving locking head 51. Figure 5 As shown, a sealing gasket 49 is provided on the inner side of the card hole 42. The sealing gasket 49 covers the four card holes 42 to prevent dust and impurities from entering the display screen 10 through the card holes 42.

[0046] In some embodiments, combined with Figures 6 to 8 As shown, a compression spring 34 is provided between the slider 50 and the boss 31 to provide the slider's restoring force. A vertical plate 52 is provided on the side of the slider 50 facing the boss 31. The boss 31 has a positioning post 35 facing the vertical plate 52. The positioning post 35 passes through one end of the compression spring 34, and the other end of the compression spring 34 abuts against the vertical plate 52. When the slider 50 is in its initial position, as... Figure 6 As shown, the buckle head 51 and the buckle hole 42 ( Figure 5 A snap-fit ​​is formed, and the initial pressure applied by the compression spring 34 to the slider 50 keeps the slider 50 in its initial position. Figure 6 When slider 50 is moved along direction C, compression spring 34 contracts, increasing the pressure on slider 50. If the push on slider 50 is released, the pressure of compression spring 34 acts as a restoring force, pushing slider 50 back to its initial position.

[0047] In some embodiments, combined with Figure 6 and Figure 7As shown, the slider 50 has a limiting cylinder 54 facing the boss 31, and the boss 31 has a corresponding rounded rectangular limiting hole 312. The limiting cylinder 54 passes into the limiting hole 312, and the cooperation between the limiting hole 312 and the limiting cylinder 54 limits the linear travel range of the slider 50. A shim 314 is attached to the outer end face of the limiting hole 312. The shim 314 covers the limiting hole 312 and the T-shaped inspection hole 313. The inspection hole 313 corresponds to the position of the compression spring 34 and the positioning post 35. When the shim 314 is not attached, the inspection hole 313 is used to check whether the compression spring 34 is installed in place.

[0048] In some embodiments, combined with Figure 7 and Figure 8 As shown, a guide plate 53 is connected to each side of the vertical plate 52. A positioning post 35 is located on a guide block 36 facing the vertical plate 52. The guide block 36 is placed between the two guide plates 53 and is slidably connected to the two guide plates 53, so that the slider 50 can maintain linear movement when moving relative to the boss 31, thereby improving the user experience. In addition, the outer end face of the slider 50 is a pressing part 501, and the outside of the pressing part 501 is provided with anti-slip protrusions 502 for easy operation.

[0049] In some embodiments, combined with Figures 6 to 8 As shown, a first magnetic member 37 is fixed in the annular groove 310 inside the boss 31, and a second magnetic member 47 is provided inside the groove 41 corresponding to the position of the first magnetic member 37. The magnetic attraction between the first magnetic member 37 and the second magnetic member 47 is used to fix the boss 31 in the groove 41. A gasket 371 is provided between the first magnetic member 37 and the body of the support member 20. The boss 31 is fixedly connected to the body of the support member 20 by four screws (not shown), and the boss 31 and the body of the support member 20 clamp the first magnetic member 37 and the gasket 371. In some embodiments, the first magnetic member 37 is a magnetic ring, and the second magnetic member 47 is an iron ring. In some embodiments, the buckle head 51 and the buckle hole 42 form a snap-fit ​​between the support member 20 and the display screen 10, and the first magnetic member 37 and the second magnetic member 47 are magnetically attracted to each other, so that the support member 20 and the display screen 10 are detachably fixedly connected. In some other embodiments, the boss of the support member and the groove of the display screen are connected by only a snap-fit ​​head and a snap-fit ​​hole; in some other embodiments, the boss of the support member and the groove of the display screen are connected by only a first magnetic attractor and a second magnetic attractor.

[0050] In at least some other embodiments, the first magnetic element is an iron ring and the second magnetic element is a magnet ring; or both the first and second magnetic elements are magnet rings, and their opposite poles are placed opposite each other to generate magnetic attraction.

[0051] In at least one other embodiment, such as Figure 9As shown, the boss 101 is located on the side of the display screen 10 facing the support member 20, and the groove 201 is located on the side of the support member 20 facing the display screen 10. Figure 9 As shown, to facilitate the movement of the buckle head 202, the relevant structure of the buckle head 202 is provided in the groove 201 of the support member 20, and the relevant structure of the buckle hole 102 is provided in the boss 101 of the display screen 10.

[0052] At least one embodiment of this application is a split-screen display, which includes a bracket 90, a display screen 10, and a connection structure for the display screen 10 according to at least one embodiment of this application. The bracket 90 is provided with at least one support member 20, and the bracket 90 is connected to the display screen 10 through the support member 20.
