Description

Technical Field

[0001] This application relates to an extended display for a laptop computer, and more specifically to a split screen display for a laptop computer. Background Art

[0002] Laptop computers have become one of the indispensable tools in modern life. The split screen display used on a laptop computer is usually externally attached to the laptop computer screen and realizes system screen expansion after being connected to the laptop computer. Users can then use multiple screens to display multiple task windows respectively, which is convenient for users to perform multitasking and improve work efficiency. Some split screen displays for laptop computers have two screens on the left and right, with a bracket set between the two screens. The two screens are rotatably connected to the bracket on both sides respectively. When folding this split screen display, usually the two screens rotate one in front of the other. After being completely folded, the two screens are respectively located in front of and behind the bracket. Since the display surfaces of the two screens face forward when in the unfolded use state, when folding by rotating one in front of the other, the display surface of the screen rotating forward faces the middle bracket, and the display surface of the other screen rotating backward faces outward. There is a risk that the exposed display surface may be damaged during storage or transportation, which needs to be improved.

[0003] Content of the Application

[0004] The purpose of this application is to overcome the above deficiencies of the prior art and provide a split screen display for a laptop computer to reduce the risk of the screen being damaged.

[0005] To achieve the above object, the present application adopts the following technical solutions: A split screen display for a laptop computer includes a back panel and a first screen. There is a transfer arm between the first screen and the back panel. One side of the transfer arm is rotatably connected to one side of the back panel through a first rotating shaft structure, and the other side of the transfer arm is rotatably connected to the side edge of the first screen through a second rotating shaft structure. The rotating shaft of the first rotating shaft structure is perpendicular to the rotating shaft of the second rotating structure; the axis of rotation for the first screen and the transfer arm to rotate forward and backward relative to the back panel is the rotating shaft of the first rotating shaft structure, and the axis of rotation for the first screen to flip up and down relative to the back panel is the rotating shaft of the second rotating shaft structure; when the split screen display is in a folded state, the first screen is stacked on the back of the back panel and the display surface of the first screen faces the back of the back panel.

[0006] The technical solution of the present application uses a transfer arm to connect the first screen and the back panel, enabling the first screen to rotate around two mutually perpendicular axes. When the first screen needs to be folded behind the back panel, the display surface of the first screen can be rotated around the second rotating shaft structure to the back, and then the transfer arm and the first screen can be rotated around the first rotating shaft structure to fit behind the back panel. The display surface of the first screen is covered by the back panel, reducing the exposed display surface during storage or transportation. Therefore, the risk of the display surface being damaged is reduced, and the safety of the product during storage or transportation is improved.

[0007] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail as follows.

[0016] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0018] References to "embodiments" in this specification mean that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0019] An embodiment of the present application is a split screen display for a laptop computer, and its specific structure is as Figure 1-10 shown.

[0020] As Figure 1 shown, the split screen display includes a back plate 30 and a first screen 10. A transfer arm 40 is provided between the first screen 10 and the back plate 30, and the transfer arm 40 is used to connect the back plate 30 and the first screen 10. Figure 1 For the usage state view of the split screen display, the direction X in which the back plate faces the user is the front, and its reverse direction is the back.

[0021] The back plate 30 of the split screen display cannot be horizontally extended or retracted. To adapt to laptop computers of different sizes, the horizontal dimension of the back plate 30 can be set to be not less than the horizontal dimension of the screen of mainstream laptop computers. For example, the common screen sizes of mainstream laptop computers are 13 - 17 inches, and the horizontal dimension of the back plate 30 should be not less than the horizontal dimension of the screen of a 17 - inch laptop computer. Alternatively, manufacturers can produce split screen displays with back plates 30 of different sizes for consumers to choose and purchase according to different sizes of laptop computers. For example, a 13 - inch split screen display corresponds to a 13 - inch laptop computer, and the horizontal dimension of its back plate 30 is not less than the horizontal dimension of the screen of a 13 - inch laptop computer.

[0022] Combined with Figure 2 and Figure 3As shown, one side of the adapter arm 40 is rotatably connected to one side of the backplane 30 through the first rotating shaft structure 50, while the other side of the adapter arm 40 is rotatably connected to the side of the first screen 10 through the second rotating shaft structure 600. The rotating shaft 501 of the first rotating shaft structure 50 is perpendicular to the rotating shaft 601 of the second rotating structure 60. The central axis of the front and back rotation of the first screen 10 and the adapter arm 40 relative to the backplane 30 is the rotating shaft 501 of the first rotating shaft structure 50, and the central axis of the up and down flipping of the first screen 10 relative to the backplane 30 is the rotating shaft 601 of the second rotating shaft structure 600. Therefore, the first screen 10 can rotate back and forth and flip up and down relative to the backplane 30 to meet the usage requirements at different angles. When the first screen 10 needs to be folded, the first screen 10 can be rotated around the rotating shaft 601 of the second rotating shaft structure 600 to make the display surface 100 of the first screen 10 face backward, and then the first screen 10 is rotated around the rotating shaft 501 of the first rotating shaft structure 50 until the first screen 10 is stacked on the back of the backplane 30. At this time, the split screen display is in a folded state, the display surface 100 of the first screen 10 faces the back of the backplane 30, the backplane 30 covers the display surface 100 of the first screen 10, and the display surface 100 of the first screen 10 is protected by the backplane 30, reducing the probability of damage.

[0023] In addition, in some embodiments, as Figure 2 shown, two magnet sheets 12 are fixed in the first screen 10, and two corresponding magnet sheets 33 are also fixed in the backplane 30. When the first screen 10 is stacked on the back of the backplane 30, the magnetic attraction between the magnet sheet 12 and the magnet sheet 33 can fix the first screen 10.

[0024] In addition, in some embodiments, as Figure 2 shown, an interface 11 is provided on the back of the first screen 10. The interface 11 includes but is not limited to HDMI interface, Type-C interface, etc. Setting the interface 11 on the back of the first screen 10 instead of on the side of the first screen 10 can reduce the length of the wire harness, and when used on the front, the connection of the wire harness is not easily observed, which is beneficial to improving the usage experience.

[0025] In some embodiments, as Figure 2 shown, there are two upper and lower first bosses 31 on one side of the back of the backplane 30. The adapter arm 40 is placed between the two first bosses 31 and the adapter arm 40 is rotatably connected to the two first bosses 31 respectively. Specifically, the first rotating shaft structure 50 includes two coaxial first rotating shafts 51 up and down. One end of the first rotating shaft 51 is fixed to the first boss 31, and the other end of the first rotating shaft 51 is fixed to the adapter arm 40 by two screws. As Figure 2As shown, one end of the first rotating shaft 51 is placed in the semicircular groove 314 of the first boss 31, and a positioning plate 510 is provided at one end of the first rotating shaft 51. The positioning plate 510 is provided with a limiting hole 511 and a right-angle outer corner 512, and the first boss 31 is provided with a limiting column 311 and a positioning right angle 312. The limiting column 311 penetrates into the limiting hole 511, and the right-angle outer corner 512 fits in the positioning right angle 312, so that the positioning plate 510 is fixed in the relative position in the first boss 31. Finally, the positioning plate 510 is fixed to the first boss 31 by two screws.

[0026] In some embodiments, Figure 2 As shown, the first boss 3131 is provided with a first cover 32, and the first cover 32 is engaged with the first boss 31 and covers the first boss 31. The first cover 32 is provided with a positioning plate 321, and the first boss 31 is provided with a positioning groove 313, and the positioning plate 321 is inserted into the positioning groove 313. The first cover 32 can cover the entire first boss 31 to prevent the first shaft 51, screws, etc. from being exposed.

[0027] In some embodiments, Figure 3 As shown, the rotation axis 601 of the second rotation axis structure 600 is colinear with the horizontal center line 101 of the first screen 10, so when the first screen 10 is turned upside down around the rotation axis 601 of the second rotation axis structure 600, the height of the center line 101 of the first screen 10 remains unchanged, and the height of the first screen 10 is the same in both the state where the display surface 100 of the first screen 10 faces backward and the state where the display surface 100 faces forward. When the first screen 10 is superimposed on the back of the back plate 30, there will be no situation where part of the first screen 10 is not covered by the back plate 30 due to turning upside down.

[0028] In some embodiments, in combination Figure 3 and Figure 4 As shown, the second rotating shaft structure 600 includes a second rotating shaft 60, and the second rotating shaft 60 includes a central shaft 63 and two parallel connecting plates 61 and 62 that can rotate relative to each other. The central shaft 63 connects the middle position of the connecting plates 61 and 62, and the relative rotation axis of the connecting plates 61 and 62 is the central axis of the central shaft 63 (i.e., the rotation axis 601 of the second rotating shaft structure 600). Figure 4 As shown, a shorter connecting plate 61 is placed in the strip groove 13 on the side of the first screen 10 and is fixedly connected to the side of the first screen 10 by a plurality of screws, and the middle shaft 63 passes through the middle hole 131 of the strip groove 13; Figure 3 As shown, a longer connecting plate 62 is placed in the strip groove 41 on the side of the transfer arm 40 and is fixedly connected to the side of the transfer arm 40 by a plurality of screws, and the middle shaft 63 passes through the middle hole 411 of the strip groove 41. In addition, in other embodiments, as Figure 3As shown, the back plate 30 is provided with a clearance groove 34 on the side corresponding to the transfer arm 40. By providing the clearance groove 34, the rotation range of the transfer arm 40 can be increased, that is, the angle range of the first screen 10 rotating forward is increased.

[0029] In some embodiments, Figure 1 As shown, the split screen display further includes a second screen 20, which is rotatably connected to one side of the front of the back plate 30. The second screen 20 and the first screen 10 are connected to both sides of the back plate 30 respectively. Figure 5 As shown, two upper and lower second bosses 35 are provided on one side of the front side of the back plate 30 , one side of the second screen 20 is placed between the two second bosses 35 , and the second screen 20 is rotatably connected to the two second bosses 35 respectively.

[0030] In some embodiments, Figure 5 As shown, the second screen 20 is rotatably connected with the second boss 35 through two upper and lower third shafts 71. One end of the third shaft 71 is fixed to the second boss 35, and the other end of the third shaft 71 is fixed in the second screen 20. Specifically, one end of the third shaft 71 is placed in the semicircular groove 354, and one end of the third shaft 71 is provided with a positioning plate 710, and the positioning plate 710 is provided with a limiting hole 711 and a right-angle outer corner 712. The second boss 35 is provided with a limiting column 351 and a positioning right angle 352. The limiting column 351 penetrates the limiting hole 711, and the right-angle outer corner 712 fits in the positioning right angle 352, so that the positioning plate 710 is conveniently fixed in the relative position in the first boss 31. Finally, the positioning plate 710 is fixed to the second boss 35 by two screws.

[0031] In some embodiments, Figure 5 As shown, the second boss 35 is provided with a second cover 36, which is engaged with the second boss 35 and covers the second boss 35. The second cover 36 is provided with a positioning plate 361, and the second boss 35 is provided with a positioning groove 353, and the positioning plate 361 is inserted into the positioning groove 353. The second cover 36 can cover the entire second boss 35 to prevent the third shaft 71, screws, etc. from being exposed.

[0032] In some embodiments, Figure 6 As shown, an interface 21 is provided on the back of the second screen 20, and the interface 21 includes but is not limited to an HDMI interface, a Type-C interface, etc. By providing the interface 21 on the back of the second screen 20 instead of on the side of the second screen 20, the length of the wiring harness can be reduced, and when used from the front, the connector of the wiring harness is not easily observed, which is conducive to improving the user experience.

[0033] In some embodiments, Figure 6As shown, a support plate 37 that can be opened is provided behind the back plate 30. The upper part of the support plate 37 is rotationally connected to the back plate 30 through two small damping rotating shafts 38. When using the split-screen display, the back plate 30 stands upright on the desktop behind the laptop computer display screen. By unfolding the support plate 37 backward and supporting it on the desktop, the split-screen display can be stably placed on the desktop.

[0034] Figure 7 This is one of the usage states of the split-screen display, in which the first screen 10 rotates backward, and its display surface 100 can be observed by the user at the side and rear. Figure 8 This is the state during the flipping process of the first screen 10 of the split-screen display. Keep flipping the first screen 10 along direction A until the first screen 10 is flush with the adapter arm 40, as shown in Figure 9 the state shown. If the support plate 37 is in the open state, as shown in Figure 9 the figure, the support plate 37 can be retracted, and then rotate the first screen 10 backward along direction B until the first screen 10 is stacked on the back of the back plate 30. After folding the first screen 10, rotate the second screen 20 along direction C until the second screen 20 is stacked on the front of the back plate 30, and the split-screen display is then folded to obtain the state shown in Figure 10 the figure. In Figure 10 this state, the display surfaces of both the first screen 10 and the second screen 20 are covered by the back plate 30, and no display surface is exposed. Therefore, the risk of damage to the display surface is reduced, and the safety during product storage or transportation is improved.
