Description

Technical Field

[0001] The present application relates to an extended display of a notebook computer, and more specifically to a split-screen display device. Background Art

[0002] Laptop computers are one of the most common computer terminals on the market. Generally, laptop computers consist of a single display screen and a flat computer body. Split-screen display devices available on the market can be mounted on the laptop screen and can expand the screen after being connected to the laptop, so that users can use more than one screen at the same time, which improves the convenience of use. Some split-screen display devices include a left screen and / or a right screen, and some split-screen display devices also include an upper screen. When in use, the upper screen is located above the laptop's own screen and the display surface of the upper screen faces the user. The rotation axis of the upper screen is usually a horizontal axis, so the upper screen can only be flipped back and forth around the horizontal axis. The angle range of the display surface of the upper screen that can be observed is relatively narrow and needs to be improved.

[0003] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned deficiencies of the prior art and to provide a split-screen display device that increases the freedom of movement of the upper screen to expand the viewing angle range of its display surface.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a split-screen display device, which includes an intermediate bracket and an upper screen, the intermediate bracket is used to be fixed on the back of the laptop screen, the intermediate bracket is connected to the upper screen through a horizontal bar, the horizontal bar is rotationally connected to the intermediate bracket, and the rotation axis of the horizontal bar rotating around the middle bracket is the central axis of the horizontal bar; the upper screen is rotationally connected to the horizontal bar, and the rotation axis of the upper screen rotating around the horizontal bar is perpendicular to the central axis of the horizontal bar.

[0006] In this application, the upper screen is connected to the middle bracket via a horizontal bar. The horizontal bar has rotational freedom relative to the middle bracket, and the upper screen also has rotational freedom relative to the horizontal bar. The rotation axis of the upper screen relative to the horizontal bar is perpendicular to the rotation axis of the horizontal bar relative to the middle bracket. In other words, the upper screen has rotational freedom in two directions relative to the middle bracket. This increases the upper screen's freedom of movement and expands the viewing angle range of the upper screen display surface. When in use, the upper screen can be rotated so that its display surface faces the front, back, left, and right directions of the laptop computer, meeting the need to observe the content displayed on the upper screen from different angles and improving ease of use. On the other hand, when folding the upper screen, the display surface of the upper screen can be folded toward the surface of the middle bracket. This prevents the display surface of the upper screen from facing outward and improves protection of the upper screen display surface.

[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.

[0014] In order to make the purpose, technical solutions and advantages of this application more clear, this application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0015] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0016] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0017] The embodiment of the present application is a split-screen display device, and its specific structure is as follows Figure 1-6 shown.

[0018] like Figure 1 As shown, the split-screen display device includes a middle bracket 10 and an upper screen 20. The middle bracket 10 is used to be fixed to the back of the laptop screen. On both sides of the middle bracket 10 are horizontally extendable side brackets 11, which clamp the laptop screen from both sides. The width between the side brackets 11 can be adjusted as needed to accommodate laptop screens of different sizes.

[0019] In some embodiments, such as Figure 1 As shown, a screen, namely a left screen 12 and a right screen 13, can be hinged on each of the two side frames 11. In other embodiments, only the left screen or the right screen can be used. Figure 1 As shown, six buttons 14 are provided above the middle bracket 10 , which can be used to set and adjust the brightness of the upper screen 20 , the left screen 12 , and the right screen 13 .

[0020] In some embodiments, such as Figure 2 and Figure 3 As shown, the middle bracket 10 is connected to the upper screen 20 via a horizontal bar 30. The horizontal bar 30 is rotatably connected to the middle bracket 10. Specifically, two rotating shaft seats 15 are provided on the upper portion of the back of the middle bracket 10, and the horizontal bar 30 is provided between the two rotating shaft seats 15. Rotating cylinders 31 are respectively provided at both ends of the horizontal bar 30. The rotating shaft seats 15 are provided with corresponding circular holes 151 on the side facing the horizontal bar 30. The outer diameter of the rotating cylinder 31 is equal to the inner diameter of the circular hole 151. The rotating cylinders 31 are inserted into the circular holes 151 one by one, so that the horizontal bar 30 and the middle bracket 10 are rotatably connected. Therefore, the rotation axis of the horizontal bar 30 rotating around the middle bracket 10 is the central axis of the horizontal bar 30, which is also the line connecting the centers of the rotating cylinders 31 at both ends of the horizontal bar 30.

[0021] In some embodiments, such as Figure 2 and Figure 3 As shown, the upper screen 20 is rotationally connected to the horizontal bar 30, and the axis of rotation about which the upper screen 20 rotates is perpendicular to the central axis of the horizontal bar 30. Specifically, the horizontal bar 30 is rotationally connected to the upper screen 20 via a rotating shaft assembly 40. The rotating shaft assembly 40 includes a central tube 43, a first plate 41, and a second plate 42. The second plate 42 is parallel to the first plate 41, while the central tube 43 is perpendicular to the first and second plates 41, 42. The central tube 43 is fixedly connected to the first plate 41, while the second plate 42 is rotationally connected to the central tube 43. The first plate 41 is fixedly connected to the upper screen 20, while the second plate 42 is fixedly connected to the horizontal bar 30. Therefore, when the upper screen 20 rotates relative to the horizontal bar 30, the first plate 41 rotates with the upper screen 20, while the second plate 42 remains fixed to the horizontal bar 30 and rotates relative to the central tube 43.

[0022] In some embodiments, such as Figure 2 and Figure 3As shown, the first plate 41 and the middle cylinder 43 are integrally formed, and the middle cylinder 43 is positioned in the middle of the first plate 41. The first plate 41, the second plate 42, and the middle cylinder 43 can all be made of metal, such as zinc alloy. Furthermore, the second plate 42 and the middle cylinder 43 are connected by a fastening screw 44, which passes through the second plate 42 and is screwed into the middle cylinder 43. Tightening the fastening screw 44 increases the rotational resistance between the second plate 42 and the middle cylinder 43, thereby increasing the rotational resistance of the upper screen 20 relative to the horizontal bar 30. Conversely, tightening the fastening screw 44 reduces the rotational resistance between the second plate 42 and the middle cylinder 43, thereby reducing the rotational resistance of the upper screen 20 relative to the horizontal bar 30.

[0023] In some embodiments, such as Figure 3 As shown, a first groove 21 is provided on one side of the upper screen 20, and the first plate 41 is placed in the first groove 21 and fixedly connected to the upper screen 20 by screws. The first groove 21 is provided with a middle hole 211, and the middle tube 43 is inserted into the middle hole 211. Figure 2 As shown, the cross bar 30 is provided with a second groove 33 , and the second plate 42 is placed in the second groove 33 and fixedly connected to the second groove 33 of the cross bar 30 by screws.

[0024] In some embodiments, such as Figure 2 and Figure 3 As shown, one end of the middle tube 43 is connected to the upper screen 20, and the other end of the middle tube 43 is connected to the horizontal bar 30. The horizontal bar 30 is hollow, and both ends of the horizontal bar 30 are provided with openings 32 and are connected to the middle bracket 10 through the openings 32. The circuit board inside the upper screen 20 and the main circuit board inside the middle bracket 10 are connected by a wiring harness 90 (see Figure 2 The wiring harnesses 90 can pass through the middle tube 43 and the horizontal bar 30. This in-axis wiring structure avoids the wiring harnesses 90 from being exposed, improves the protection of the wiring harnesses 90, and improves the appearance of the product.

[0025] The rotation axis of the upper screen 20 relative to the horizontal bar 30 is perpendicular to the rotation axis of the horizontal bar 30 relative to the middle bracket 10. Therefore, the upper screen 20 has rotational freedom in two directions relative to the middle bracket 10, and the movement freedom of the upper screen 20 is increased, which expands the observation angle range of the display surface of the upper screen 20. Figure 1 In the example, the display surface of the upper screen 20 faces the rear, and the interface displayed on the upper screen 20 can be observed from behind the laptop. Figure 4 In the state shown, the interface displayed on the upper screen 20 can be observed on the right side of the laptop. Similarly, if the upper screen 20 is rotated to the left around the horizontal bar 30, the interface displayed on the upper screen 20 can be observed on the left side of the laptop. Figure 4 Continue to rotate the upper screen 20 degrees until Figure 5In the state shown, the display surface 201 of the upper screen 20 is facing the front of the laptop computer, and the display surface 201 of the upper screen 20 can be observed in front of the laptop computer.

[0026] When the upper screen 20 is folded, the display surface of the upper screen 20 is folded toward the surface of the middle bracket 10 to form a Figure 6 As shown in the state, the display surface of the upper screen 20 is avoided from being easily damaged when facing outward, thereby improving the protection of the display surface of the upper screen 20.

[0027] In other embodiments, Figure 3 As shown, two magnets 34 can also be optionally provided in the horizontal bar 30, and an iron block 22 can be provided at the corresponding position of the upper screen 20. When the upper screen 20 is rotated to face forward or backward, the magnetic attraction between the magnet 34 and the iron block 22 can help fix the position of the upper screen 20 relative to the horizontal bar 30.
