Description

Technical Field

[0001] The present invention relates to the field of display devices, and in particular to a flip screen. Background Art

[0002] In the current context of diversified development of electronic devices, the screen, as a key component for information interaction and display, has a flip design that greatly expands the usage scenarios and functional diversity of electronic devices. It is widely used in many fields such as computers, vehicle systems, industrial control equipment, and medical equipment.

[0003] In the related art, the rack and pinion transmission mechanism is widely used in some screen flipping designs. When in use, a rotating shaft is set on each side of the screen, and a set of gears and racks that mesh with each other are connected at the opposite end of the rotating shaft that is connected to the screen. The gears are driven to rotate by moving the racks, thereby driving the screen to flip. However, this mechanism often has the problem of inconsistent transmission during actual application. For example, the gears and racks on both sides of the screen may be affected by errors in manufacturing and assembly, which may cause deviations in the final force they receive, resulting in asynchronous transmission on both sides of the screen. In addition, there is a transmission gap in the gear and rack transmission itself, which may also cause inconsistent or asynchronous rotation angles on both sides of the screen. These all make the screen prone to tilting, freezing, and other phenomena during the flipping process. Summary of the Invention

[0040] The present invention is described below based on the following embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid obscuring the essence of the present invention, well-known methods, processes, procedures, and components are not described in detail.

[0041] Furthermore, persons of ordinary skill in the art will appreciate that the figures provided herein are for illustration purposes only and are not necessarily drawn to scale.

[0042] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include," "comprising," and similar words should be construed in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to."

[0043] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0044] The flip screen provided by the present invention always maintains a stable and smooth state during the flipping process, and the movement is smooth and coherent, which can bring a comfortable and efficient use experience to the user.

[0045] The flip screen provided by the present invention is described in detail below with reference to the accompanying drawings.

[0046] like Figure 1 and Figure 2 As shown, the flip screen provided by the embodiment of the present invention includes a flip device 10 and a screen assembly 20, wherein the flip device 10 includes a mounting base 11 and a translation assembly 12, a flip assembly 13 and a traction assembly 14 arranged on the mounting base 11, and the screen assembly 20 is movably installed in the mounting base 11.

[0047] like Figure 1 As shown, along the length direction of the mounting base 11 (i.e., the direction corresponding to the longer side of the mounting base 11), a translation assembly 12 and a flip assembly 13 are disposed on the left side of the mounting base 11, and a translation assembly 12 and a flip assembly 13 are also disposed on the right side of the mounting base 11. It should be noted that the length direction of the mounting base 11 is consistent with, or substantially parallel to, the length direction of the screen assembly 20, and the width direction of the mounting base 11 is consistent with, or substantially parallel to, the width direction of the screen assembly 20.

[0048] The traction assembly 14 includes a pair of guide pillars 141, a traction rope 142 and a driving mechanism 143. A pair of guide pillars 141 is provided on both sides of the mounting base 11 along its length direction. Both ends of the traction rope 142 are connected to the driving mechanism 143 and are cross-wound between the two pairs of guide pillars 141.

[0049] The translation assembly 12 includes a sliding member 121, which is slidably mounted on the mounting base 11 and fixedly connected to a traction rope 142, so that the two sliding members 121 are driven to slide by the traction rope 142. The screen assembly 20 is rotatably connected to the sliding member 121 on both sides along its length.

[0050] The flip assembly 13 includes a connecting rod 131 , and both ends of the connecting rod 131 are rotatably connected to the screen assembly 20 and the mounting base 11 respectively.

[0051] Driven by the driving mechanism 143 , the traction rope 142 drives the screen assembly 20 to slide relative to the mounting base 11 through the sliding member 121 . During the sliding process, the screen assembly 20 is flipped under the traction of the flip assembly 13 .

[0052] The screen assembly 20, the sliding member 121, the connecting rod 131 and the mounting seat 11 of the present invention form a connecting rod structure, and a traction rope 142 connected by a driving mechanism 143 drives the two sliding members 121 in the length direction of the screen assembly 20 to slide synchronously, thereby driving the screen assembly 20 to slide relative to the mounting seat 11. During the sliding process, the screen assembly 20 is constrained by the connecting rod 131 and the mounting seat 11, and the screen assembly 20 is flipped under the traction of the connecting rod 131. Since the traction rope 142 and the sliding member 121 are fixedly connected, and the same traction rope 142 is used to drive the two sliding members 121 at the same time, the flip screen of the present invention can ensure the consistency of the sliding of the two sides of the screen assembly, and then ensure the synchronization of the flipping of the two sides of the screen assembly 20, thereby improving the smoothness of the flipping of the screen assembly 20, avoiding problems such as screen distortion caused by unbalanced force on both sides of the screen assembly 20 during the flipping process, and extending the service life of the screen assembly 20.

[0053] In addition, since the entire flipping device 10 is driven by the traction rope 142, the entire flipping process is smooth and basically has no jamming. Therefore, the reliability of the flipping of the screen assembly 20 can be further improved and the service life of the entire flip screen can be extended.

[0054] In the above embodiment, both the mounting base 11 and the screen assembly 20 can adopt a rectangular structure. The screen assembly 20 is installed in the mounting base 11 in a composite movable manner, that is, the screen assembly 20 can perform two movements simultaneously relative to the mounting base 11: on the one hand, the screen assembly 20 can slide linearly along the width direction of the mounting base 11 (that is, the direction corresponding to the shorter side length of the mounting base 11) to achieve position translation along the width direction of the mounting base 11; on the other hand, one end of the screen assembly 20 in the width direction can also rotate with a preset position in the width direction of the mounting base 11 (for example, it can be a position in the top area, a position in the middle area, and a position in the bottom area in the width direction of the mounting base 11) as a fulcrum, and the other end of the screen assembly 20 in the width direction flips in a direction away from the mounting base 11 to adjust the angle of the screen. Through the above movement, the screen assembly 20 is rotated from Figure 3 The initial state shown is transformed into Figure 4 The two movements of the screen assembly 20 relative to the mounting base 11 do not interfere with each other and can be performed simultaneously. For example, while sliding the screen assembly 20 to adjust its position along its width, the screen assembly 20 can be flipped away from the mounting base 11 to change the viewing angle. This can greatly enhance the flexibility and ease of use of the screen assembly 20 after installation.

[0055] Specifically, along the length direction of the mounting base 11, a pair of guide pillars 141 is provided on the left side of the mounting base 11, and a pair of guide pillars 141 is also provided on the right side of the mounting base 11. Each pair of guide pillars 141 includes two guide pillars. The two guide pillars of each pair of guide pillars 141 can be provided along the width direction of the mounting base, that is, the four guide pillars are distributed at four different points in space. When these four points are connected in sequence clockwise or counterclockwise, the closed quadrilateral formed can be a rectangle.

[0056] like Figure 2 As shown, four guide pillars are provided, starting from the right bottom guide pillar, and in a counterclockwise direction, they are the first guide pillar, the second guide pillar, the third guide pillar, and the fourth guide pillar. One end of the traction rope 142 is connected to the driving mechanism 143, and the other end thereof passes around the outside of the first guide pillar and extends to the outside of the second guide pillar, then extends to the outside of the third guide pillar, passes around the outside of the third guide pillar and extends to the outside of the fourth guide pillar, and finally passes back around the outside of the fourth guide pillar and connects to the driving mechanism 143. In this way, the traction ropes are arranged in a cross pattern, so that the sliding members on both sides can rise or fall synchronously.

[0057] By connecting both ends of the traction rope 142 to the same driving mechanism 143 , a closed-loop transmission system is formed, and driven by a single power source, it is possible to ensure synchronization of driving the sliding members 121 on the left and right sides of the mounting seat 11 in the longitudinal direction.

[0058] Specifically, the left side wall of the screen assembly 20 along its length direction is rotatably connected to the left sliding member 121, and the right side wall of the screen assembly 20 along its length direction is rotatably connected to the right sliding member 121.

[0059] like Figure 5 As shown, the screen assembly 20 may include a screen 21 and a housing 22, wherein the screen 21 is disposed in the housing 22. A groove 221 is provided on the back of the housing 22. One end of the connecting rod 131 is located in the groove 221 and is rotatably connected to the housing 22. In order to rationally layout the circuit board connected to the screen 21 and enhance the firmness of the connection between the connecting rod 131 and the housing 22, the screen assembly 20 may be designed to have a thick upper region and a thin lower region.

[0060] By concealing the pivoting connection point at one end of the connecting rod 131 within a groove 221 on the back of the housing 22, the connecting end of the connecting rod 131 is prevented from being directly exposed or protruding from the surface of the housing 22. This reduces the space occupied by the connecting rod 131 and ensures structural stability. Furthermore, the groove 221 constrains the rotational trajectory of the connecting rod 131, reducing its degrees of freedom and guiding the connecting rod 131 to rotate in a predetermined direction, minimizing any shaking or deviation, and ensuring a smoother and more stable opening and closing of the screen assembly 20.

[0061] In one embodiment, when the mounting base 11 and the screen assembly 20 are placed horizontally and the translation assembly 12 is arranged on the left and right sides of the length direction of the mounting base 11, the sliding direction of the sliding member 121 is parallel to the width direction of the screen assembly 20, and the axis of the rotational connection portion between the screen assembly 20 and the sliding member 121 is parallel to the length direction of the screen assembly 20. In this connection mode, the upper end of the screen assembly 20, which is rotationally connected to the sliding member 121 along its width direction, slides along the width direction of the screen assembly 20, and the lower end of the screen assembly 20 flips in a direction away from the mounting base 11. Alternatively, in this connection mode, the lower end of the screen assembly 20, which is rotationally connected to the sliding member 121 along the width direction of the screen assembly 20, slides along the width direction of the screen assembly 20, and the upper end of the screen assembly 20 flips in a direction away from the mounting base 11.

[0062] It is understood that, when the mounting base 11 and screen assembly 20 are placed horizontally, a set of translation assemblies 12 and flip assemblies 13 can also be provided at the upper and lower ends of the width direction of the screen assembly 20, with the sliding direction of the translation assembly 12 being parallel to the length direction of the screen assembly 20, and the axis of the rotational connection between the screen assembly 20 and the slider 121 being parallel to the width direction of the screen assembly 20. In this connection method, the left side of the screen assembly 20 that is rotationally connected to the slider 121 along its length direction slides along the length direction of the screen assembly 20, and the right side of the screen assembly 20 flips away from the mounting base 11. Alternatively, in this connection method, the right side of the screen assembly 20 that is rotationally connected to the slider 121 along its length direction slides along the length direction of the screen assembly 20, and the left side of the screen assembly 20 flips away from the mounting base 11.

[0063] Specifically, the screen assembly 20 can be rotatably connected to the sliding member 121 via a rotating shaft 23 or a spherical pair. When the rotating shaft 23 is used, the axis of the rotating shaft 23 is parallel to the length of the screen assembly 20, and the rotating shaft 23 is located in the top area of the screen assembly 20. When the spherical pair is used, a ball socket can be provided on the side of the sliding member 121, and a sphere can be provided on the side of the screen assembly 20. The sphere is rotatably connected in the ball socket, and the sphere is located in the top area of the screen assembly 20. Of course, a sphere can also be provided on the side of the sliding member 121 and a ball socket can be provided on the side of the screen assembly 20 as needed.

[0064] In the embodiment of the present invention, Figure 2 As shown, the translation assembly 12 further includes an optical axis 122 . The optical axis 122 is mounted on the mounting seat 11 , and the sliding member 121 is slidably connected to the optical axis 122 .

[0065] Specifically, the sliding member 121 can be a damping sleeve that is slidably connected to the optical axis 122. The damping sleeve can achieve precise positioning by providing resistance, preventing excessive sliding. The damping sleeve can also achieve a buffering and shock-absorbing effect by absorbing energy, reducing the impact of vibration on the screen assembly 20. The sliding speed can also be flexibly adjusted to meet the needs of different working conditions. At the same time, it can also transfer direct friction with the optical axis 122 to itself, reducing wear, suppressing swing, and enhancing operational stability, providing reliable protection for high-precision operation.

[0066] Furthermore, the translation assembly 12 also includes an axle seat pair 123, which is arranged on the mounting base 11 and distributed on both sides of the length direction of the screen assembly 20. One end of the optical axis 122 is connected to one of the axle seats in the axle seat pair 123, and the other end thereof is connected to the other axle seat in the axle seat pair 123. The axle seat pair 123 is used to support and position the optical axis 122. In addition, an elastic connection or shock-absorbing materials such as rubber pads can be used between the axle seat and the mounting base 11. When the flip screen is subjected to vibration or impact, the elastic structure can absorb and dissipate energy, reduce the vibration transferred to the optical axis 122, thereby protecting the optical axis 122, the sliding member 121 and the screen assembly 20, etc., and improving the shock resistance of the entire flip screen.

[0067] Adjustable components such as fine-tuning bolts or wedge blocks can also be provided between the shaft seat and the mounting base 11. In this way, during installation and debugging, the position and angle of the optical axis 122 can be easily fine-tuned to achieve higher installation accuracy.

[0068] In the embodiment of the present invention, Figure 2 As shown, the traction assembly 14 further includes a rope guide frame 144. The rope guide frames 144 are provided on both sides of the mounting base 11 along the length direction of the screen assembly 20, and the two rope guide frames 144 are located between the two translation assemblies 12. Two guide pillar pairs 141 are respectively formed on the corresponding rope guide frames 144.

[0069] Two rope guide frames 144 are provided as a first rope guide frame and a second rope guide frame, respectively. The first rope guide frame is provided on the left side of the mounting base 11 along the length direction of the screen assembly 20, and the second rope guide frame is provided on the right side of the mounting base 11 along the length direction of the screen assembly 20. The first rope guide frame is provided with a first guide post and a second guide post at the upper and lower ends along the width direction of the screen assembly 20, respectively. The second rope guide frame is provided with a third guide post and a fourth guide post at the upper and lower ends along the width direction of the screen assembly 20, respectively. One end of the traction rope 142 is connected to the driving mechanism 143, and the other end thereof passes around the outside of the first guide post and extends along the first rope guide frame to the outside of the second guide post, then extends to the outside of the third guide post, passes around the outside of the third guide post, extends along the second rope guide frame to the outside of the fourth guide post, and finally passes back from the outside of the fourth guide post and connects to the driving mechanism 143.

[0070] Specifically, if Figure 6 As shown, the rope guide frame 144 includes a connecting portion 1441, which connects the two guide pillars in the corresponding guide pillar pair 141; a receiving space 1442 is formed on the side of the connecting portion 1441 close to the mounting seat 11, and a through hole is provided on the side wall of the receiving space 1442; the traction rope 142 is partially located in the receiving space 1442, and passes through the through hole to pass through the receiving space 1442 and then is wrapped around the guide pillar.

[0071] By partially arranging the traction rope 142 in the accommodation space 1442, the traction rope 142 can be protected from interference and damage such as mechanical collisions, thereby helping to extend the service life of the traction rope 142. The guide pillars at both ends of the connecting portion 1441 can guide the traction rope 142 so that it is wound along a specific path, ensuring that the traction rope 142 is accurately and stably directed, avoiding problems such as rope entanglement and deviation, and thus improving the reliability and stability of the entire traction assembly 14.

[0072] Furthermore, a strip groove 1443 is provided on a side of the connecting portion 1441 away from the mounting seat 11 . The strip groove 1443 extends along the sliding direction of the sliding member 121 and has a common side wall with the accommodating space 1442 . The through hole connects the two side walls of the strip groove 1443 .

[0073] like Figure 2 As shown, the translation assembly 12 also includes a sliding seat 124, which can be fixedly set on the top of the sliding member 121. The sliding member 121 is fixedly connected to the traction rope 142 through the sliding seat 124, and the part of the sliding seat 124 connected to the traction rope 142 is slidably set in the strip groove 1443.

[0074] Furthermore, if Figure 4 As shown, the connecting portion 1441 includes a U-shaped structure and an extension plate. The U-shaped structure is provided with a U-shaped groove, which forms a strip groove 1443. The extension plate is connected to a side wall at the opening of the U-shaped structure and forms an accommodating space 1442 with the side wall.

[0075] In the embodiment of the present invention, Figure 2 and Figure 7 As shown, one side of the mounting base 11 facing the screen assembly 20 is partially recessed to form a limiting cover 111; the connecting rod 131 is a bent structure, and the protruding direction of the bent structure is consistent with the recessed direction of the limiting cover 111. The bent structure is at least partially located within the limiting cover 111 to limit the displacement of the connecting rod 131 in the length direction of the screen 21 and the displacement in the direction away from the back of the screen assembly 20.

[0076] Specifically, if Figure 5 As shown, the mounting base 11 defines a screen mounting cavity 112, and the screen assembly 20 is partially located in the screen mounting cavity 112. The translation assembly 12 is disposed outside the cavity wall of the screen mounting cavity 112 and is rotationally connected to the screen assembly 20 via a rotation axis or spherical pair passing through the cavity wall.

[0077] It is understandable that the screen assembly 20 can also be directly installed on the front of the mounting base 11, and the flip device 10 can be installed on the back of the mounting base 11. Under the action of the flip device 10, the side of the screen assembly 20 that is rotatably connected to the sliding member 121 slides relative to the mounting base 11, and the opposite side of the side of the screen assembly 20 that is rotatably connected to the sliding member 121 flips in a direction away from the mounting base 11.

[0078] like Figure 1 As shown, the flip device 10 also includes a rear shell 15, which is matched with the mounting base 11. The rear shell 15 is covered on the side of the mounting base 11 facing away from the screen assembly 20. The translation assembly 12, the flip assembly 13 and the traction assembly 14 are arranged in the internal space formed by the rear shell 15 and the mounting base 11 to fix and protect the translation assembly 12, the flip assembly 13 and the traction assembly 14.
