Technical Field

[0001] This utility model relates to the field of flip-up panel technology, specifically to a flip-up panel mechanism, a sofa, and a chair. Background Technology

[0002] Sofas and chairs are common pieces of furniture in daily life. However, existing sofas and chairs have relatively limited functions, only providing support for the body. They cannot support books or other study tools, nor do they provide a platform for people to place books or tablets while seated. People need to hold books or display devices for extended periods, which is tiring. Therefore, it is necessary to install a support platform on sofas or chairs to mount or place display devices or books, freeing up people's hands.

[0003] Existing technologies also include some designs for flip panels, which are hinged to supporting structures such as the armrests of sofas or chairs. However, these structures often only allow rotation in one or two directions and cannot adjust the flip panel to a distance suitable for the user. People often have to look down or twist their necks to see the display device on the flip panel, and maintaining this posture for a long time can be uncomfortable. Utility Model Content

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0028] Example 1

[0029] This utility model provides a flip-plate mechanism, such as Figure 1 As shown, it includes: a flip-up plate 1; a support base 2, which is suitable for fixing to a support body such as a sofa or chair; the support base 2 includes a pair of mounting plates 201; the inner surfaces of the two mounting plates 201 are each horizontally fixed with a first limiting post 202, the strength of which meets the requirements to support the entire flip-up plate 1 and related components, and the two first limiting posts 202 are symmetrically arranged; a rotating structure, which includes a first rotating component 3, a second rotating component 4 and a third rotating component 5; wherein, the first rotating component 3 is rotatably connected to the support base 2, and the first rotating component 3 is configured to rotate around the X-axis; The first rotating component 3 has a top plate 301 and side plates 302 fixed or integrally formed on both sides of the top plate 301; a first rotating shaft 303 passes through each side plate 302 and the mounting plate 201 to allow the first rotating component 3 to rotate relative to the X-axis. Here, to more clearly indicate which directions the flip plate 1 can rotate, the concepts of X-axis, Y-axis, and Z-axis are specifically introduced. This does not specifically refer to the absolute rotation of the component around the X-axis, but rather to illustrate the relative relationship between these components, and depends on the actual installation position and orientation of these components in the process; both side plates 302 are open. A first guide groove 304 is provided, which slides in conjunction with the first limiting post 202 to limit the rotation angle range of the first rotating component 3. Here, two symmetrically arranged first guide grooves 304 are designed for stability; in practice, one first guide groove 304 and a corresponding first limiting post 202 can also be designed. The second rotating component 4 is rotatably connected to the first rotating component 3, and the second rotating component 4 is configured to rotate about the Z-axis. A second rotating shaft 401 passes through one end of the second rotating component 4 and the top plate 301 to allow the second rotating component 4 to rotate relative to the Z-axis. The third rotating component 5 has a pair of third rotating shafts 501 passing through the end of the second rotating component 4 away from the second rotating shaft 401 and the third rotating component 5, so that the third rotating component 5 can rotate relative to the Y-axis; wherein, the third rotating component 5 is rotatably connected to the second rotating component 4, and the third rotating component 5 is configured to rotate around the Y-axis; the third rotating component 5 is fixedly connected to the back of the flip plate 1, so when the first rotating component 3, the second rotating component 4 or the third rotating component 5 rotates, it will drive the flip plate 1 to rotate accordingly, thereby adjusting the flip plate 1 to the position and angle required by the user.

[0030] like Figure 2 As shown, the first guide groove 304 is an arc-shaped guide groove with the central axis of the first rotating shaft 303 as the center; the first guide groove 304 covers a fan-shaped area with a central angle of 90°, as shown in the figure. The first guide groove 304 extends clockwise from the 12 o'clock position to the 3 o'clock position so that the first rotating component 3 can be fixed in the horizontal and vertical directions. Otherwise, when the user uses the flip plate 1, the flip plate will fall due to the lack of restraint and may hit the user.

[0031] like Figure 2 As shown, the top plate 301 has a second guide groove 305; the second guide groove 305 is an arc-shaped guide groove with the central axis of the second rotating shaft 401 as its center; the second guide groove 305 covers a fan-shaped area with a central angle of 180°, so as to... Figure 1 For the standard, the second guide groove 305 extends clockwise from the 6 o'clock position to the 12 o'clock position on the horizontal plane; the bottom of the second rotating component 4 near the second rotating shaft 401 is vertically fixed with a second limiting post 402 that slides with the second guide groove 305 to limit the rotation angle range of the second rotating component 4.

[0032] like Figure 1-2 As shown, a pair of corner plates 404 are symmetrically fixed to the end of the second rotating component 4 away from the second rotating shaft 401, and are fixed by screws or bolt-nut combinations or other fasteners; the third rotating shaft 501 passes through the corner plates 404. Figure 1 As shown, the second rotating component 4 is provided with a transition portion 403. The transition portion 403 is configured to limit the relative posture between different parts of the second rotating component 4, that is, to adjust the position and posture of the second rotating component 4 on both sides of the transition portion 403. The second rotating component 4 can remain on the same plane on both sides of the transition portion 403; or the transition portion 403 can be bent to form a stepped surface, and the second rotating component 4 can remain parallel on both sides of the transition portion 403, so that the flip plate 1 can be raised a certain distance to make it closer to the user; of course, the second rotating component 4 can also be made to form an angle on both sides of the transition portion 403.

[0033] like Figure 2-3 As shown, the flip plate 1 includes a front shell 101 and a back shell 102 that interlock to form an installation space. In actual operation, a display screen or other devices are usually installed on the front shell 101 to facilitate users watching videos, placing books, or writing while sitting on a sofa or chair. If a display screen is not installed on the front shell 101, the flip plate 1 can also be used as an auxiliary support arm structure. The back shell 102 has a groove that matches the connecting plate 103 for more stable installation of the connecting plate 103. The interior of the back shell 102 is designed in a grid pattern as shown in the figure, which reduces weight while ensuring a certain strength. The connecting plate 103 is fixedly installed with the third rotating component 5, thereby fixing the third rotating component 5 relative to the flip plate 1. The back shell 102 is embedded with an annular cavity 104. The annular cavity 104 has multiple through holes 105, which can be used to install small devices for playing sound or heat dissipation.

[0034] like Figure 6-7As shown, the third rotating component 5 is also provided with an angle adjustment mechanism 6 to fix the flip plate 1 at multiple angles. The angle adjustment mechanism 6 adopts the angle adjustment mechanism in the prior art, or adopts the technology in sections
