Description

Technical Field

[0001] This utility model relates to the field of screen installation, and in particular to a flipping device and a flipping screen. Background Technology

[0002] As electronic devices evolve towards multi-functionality and multi-form designs, the screen, as a core interactive component, has become a key technology for enhancing user experience through its flip-screen design, widely used in computers, automotive information systems, industrial control terminals, and medical equipment. Through screen flipping functionality, devices can flexibly adapt to different usage scenarios, enabling diverse interaction modes.

[0003] In related technologies, rack and pinion transmission mechanisms are widely used due to their simple structure and high transmission efficiency. This mechanism typically has rotating shafts on both sides of the screen, with one end fixedly connected to the screen and the other end connected to a meshing gear and rack. Driving the rack moves the gear, causing it to rotate, thus achieving the screen's flipping motion. However, in practical applications, traditional screen flipping transmission solutions still have room for improvement. For example, due to wear and tear on transmission components from long-term use and external environmental interference, the screen may experience stuttering or uneven rotation during flipping, affecting the user experience and potentially reducing the device's reliability and lifespan. Therefore, there is an urgent need to develop a solution that ensures smooth screen flipping and improves operational stability. Summary of the Invention

[0033] The present invention will now be described based on 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, but well-known methods, processes, procedures, and elements are not described in detail in order to avoid obscuring the essence of the present invention.

[0034] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0035] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0036] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] The flipping device provided by this utility model is used to flip screen components. It maintains a stable and smooth state throughout the flipping process, and the action is smooth and continuous, which can bring users a comfortable and efficient user experience.

[0038] The flipping device provided by this utility model will be described in detail below with reference to the accompanying drawings.

[0039] like Figure 1 As shown, the flipping device provided in this embodiment of the present invention includes a mounting base 11 and a translation component 12 and a flipping component 13 disposed in the mounting base 11, wherein the screen component 20 is movably mounted in the mounting base 11.

[0040] The translation component 12 includes a slider 121, which is slidably mounted on the mounting base 11 for rotational connection with the screen component 20 at a first position.

[0041] The flip assembly 13 includes a link 131, the first end of which is rotatably connected to the mounting base 11, and the second end of which is rotatably connected to the second position of the screen assembly 20; wherein the first position and the second position are offset in the sliding direction of the slider 121.

[0042] The slider 121 can drive the screen assembly 20 to slide along the mounting base 11. During the sliding process, the screen assembly 20 is flipped under the pull of the connecting rod 131. This utility model can ensure that the screen assembly 20 flips smoothly and enhance the accuracy of screen flipping.

[0043] In this invention, the screen assembly 20, slider 121, connecting rod 131, and mounting base 11 form a linkage structure. The slider 121 drives the screen assembly 20 to slide relative to the mounting base 11. During the sliding process, the screen assembly 20 is constrained by the connecting rod 131 and the mounting base 11. Under the pull of the connecting rod 131, the screen assembly flips. The entire flipping process is smooth with virtually no jamming. Therefore, this invention ensures the smooth flipping of the screen assembly 20, enhances the accuracy and reliability of the screen assembly 20's flipping, and further extends the service life of the entire screen assembly 20.

[0044] In this embodiment, only one set of translation component 12 and flip component 13 can be provided. In this case, the first position and the second position of the screen component 20 can both be set in the middle region of the screen component 20 in its length direction. The length direction of the screen component 20 can be understood as the direction corresponding to the longer side of the screen component 20. The sliding direction of the slider 121 can be understood as parallel to the width direction of the screen component 20, and the width direction of the screen component 20 can be understood as the direction corresponding to the shorter side of the screen component 20.

[0045] In a specific embodiment, such as Figure 1 and Figure 2 As shown, the translation assembly 12 also includes a first bearing 122, a second bearing 123, and an optical axis 124. The first bearing 122 and the second bearing 123 are both disposed opposite each other on the mounting base 11 along the sliding direction of the slider 121. One end of the optical axis 124 is fixedly connected to the first bearing 122, and the other end is fixedly connected to the second bearing 123. The first bearing 122 and the second bearing 123 are used to support and position the optical axis 124.

[0046] In addition, an elastic connection or shock-absorbing materials such as rubber pads can be used between the shaft seat and the mounting base 11. When the flipping device is subjected to vibration or impact, the elastic structure can absorb and dissipate energy, reduce the vibration transmitted to the optical shaft 124, thereby protecting the optical shaft 124, the sliding member 121 and the screen assembly 20, and improving the shock resistance of the entire flipping device.

[0047] The slider 121 can be a damping sleeve, which is slidably connected to the optical axis 124. The damping sleeve is rotatably connected to the screen assembly 20 at its first position. When the damping sleeve slides on the optical axis 124, it drives the screen assembly 20 to slide along the sliding direction of the damping sleeve.

[0048] The damping sleeve can achieve precise positioning by providing its own resistance, avoiding excessive sliding; and the damping sleeve can absorb energy to achieve a buffering and shock absorption effect, reducing the impact of vibration on the screen component 20; it can also flexibly adjust the sliding speed to meet the needs of different working conditions; at the same time, it can transfer the direct friction between itself and the optical axis 124 to itself, reducing wear, suppressing swaying, enhancing operational stability, and providing a reliable guarantee for high-precision operation.

[0049] Adjustable components such as fine-tuning bolts or wedge blocks can also be installed between the shaft seat and the mounting base 11. This allows for easy fine-tuning of the position and angle of the optical axis 124 during installation and debugging, achieving high installation accuracy.

[0050] In one specific embodiment, the mounting base 11 has a frame structure, and the connecting rod 131 has a bent structure. The bent section of the connecting rod 131 protrudes towards the rear side of the mounting base 11, and the first end of the connecting rod 131 is connected to the rear side of the mounting base 11. Specifically, as shown... Figure 3 As shown, the flipping assembly 13 also includes a fixing member 132 and a bushing 133. The fixing member 132 can be fixedly installed on the rear side of the mounting base 11, and the first end of the connecting rod 131 is rotatably connected to the fixing member 132 through the bushing 133.

[0051] Furthermore, such as Figure 4 and Figure 5 As shown, the mounting base 11 is also provided with a limiting cover 111. The limiting cover 111 has a U-shaped structure. The two ends of the U-shaped structure along the length direction of the screen assembly 20 are connected to the rear side of the mounting base 11. The U-shaped structure has a U-shaped through groove 1111 along the width direction of the screen assembly 20. The bent structure part is located inside the limiting cover 111. The first end and the second end of the connecting rod 131 extend out of the U-shaped through groove 1111 respectively. This allows the connecting rod 131 to move in the width direction of the screen assembly 20, limiting the displacement of the connecting rod 131 in the length direction of the screen and the displacement in the direction away from the back of the screen assembly 20.

[0052] In other embodiments, such as Figure 1As shown, along the length of the mounting base 11 (i.e., the direction corresponding to the longer side of the mounting base 11), a set of translation components 12 and flipping components 13 are arranged on the left side of the mounting base 11, and a set of translation components 12 and flipping components 13 are also arranged 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. The length direction of the mounting base 11 is perpendicular to the sliding direction of the slider 121.

[0053] When two sets of translation components 12 and flip components 13 are provided, the two sets of first positions and second positions of the screen component 20 are located on both sides of the screen component 20 along its length. Specifically, one of the first positions can be located on the left side wall of the screen component 20, and the other first position can be located on the right side wall of the screen component 20. One of the second positions can be located on the left side of the screen component 20, and the other second position can be located on the right side of the screen component 20.

[0054] For example, when both the mounting base 11 and the screen assembly 20 are placed horizontally, and the translation components 12 are positioned on the left and right sides of the mounting base 11 along its length, the sliding direction of the slider 121 is parallel to the width direction of the screen assembly 20, and the axis of the rotatable connection between the screen assembly 20 and the slider 121 is parallel to the length direction of the screen assembly 20. In this connection method, the upper end of the screen assembly 20, which is rotatably connected to the slider 121 along its width direction, slides along the width direction of the screen assembly 20, while the lower end of the screen assembly 20 flips away from the mounting base 11. Alternatively, in this connection method, the lower end of the screen assembly 20, which is rotatably connected to the slider along its width direction, slides along the width direction of the screen assembly 20, while the upper end of the screen assembly 20 flips away from the mounting base 11.

[0055] By setting a set of translation components 12 and a set of flipping components 13 on the left and right sides of the mounting base 11 respectively, the synchronicity of the flipping of the screen assembly 20 on both sides can be ensured, the stability of the flipping of the screen assembly 20 can be improved, and problems such as screen distortion caused by uneven force on both sides of the screen assembly 20 during the flipping process can be avoided, thus extending the service life of the screen assembly 20.

[0056] In this embodiment, the same driving component 14 can be used to drive the two sliders 121, so that the two sliders 121 can slide on their respective optical axes 124, thereby ensuring the consistency of sliding on both sides of the screen component 20.

[0057] In a specific embodiment, such as Figure 1As shown, the drive assembly 14 includes guide pillars 141, a traction rope 142, and a drive mechanism 143. Two guide pillars 141 are arranged opposite each other along the sliding direction at one sliding member 121, and two guide pillars 141 are arranged opposite each other along the sliding direction at another sliding member 121. Both ends of the traction rope 142 are connected to the drive mechanism 143. The rope body of the traction rope 142 is wound around each guide pillar 141 and is arranged in a cross pattern between each guide pillar 141. The two sliding members 121 are fixedly connected to the traction rope 142 respectively.

[0058] Driven by the drive mechanism 143, the traction rope 142 drives the screen assembly 20 to slide relative to the mounting base 11 through the slider 121. During the sliding process, the screen assembly 20 is flipped under the pull of the flipping component 13.

[0059] like Figure 1 As shown, four guide pillars 141 are set, starting from the bottom right guide pillar 141 and proceeding counterclockwise as the first guide pillar, second guide pillar, third guide pillar, and fourth guide pillar. One end of the traction rope 142 is connected to the drive mechanism 143, and the other end passes around the outside of the first guide pillar and extends to the outside of the second guide pillar, then 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 loops back from the outside of the fourth guide pillar and connects to the drive mechanism 143. In this way, the traction rope 142 is arranged in a crisscross pattern, so that the sliding members 121 on both sides can rise or fall synchronously.

[0060] By connecting the two ends of the traction rope 142 to the same drive mechanism 143, a closed-loop transmission system is formed and driven by a single power source, which can ensure the synchronicity of the drive of the sliding parts 121 on the left and right sides of the mounting base 11 in the length direction.

[0061] In another specific embodiment, the drive assembly 14 includes a telescopic structure and a push rod. The force-receiving end of the push rod is connected to the telescopic structure, and the two force-applying ends of the push rod are respectively connected to two sliding members 121. Specifically, the telescopic structure can be a cylinder, a hydraulic cylinder, a spring telescopic rod, or a crank-slider mechanism, etc.

[0062] Driven by the telescopic structure, the push rod pushes the screen assembly 20 to slide relative to the mounting base 11 through the slider 121. During the sliding process, the screen assembly 20 is flipped under the pull of the flipping component 13.

[0063] Based on the flipping device provided by this utility model, such as Figure 6 As shown, this utility model also provides a flip screen, which includes a screen assembly 20 and the aforementioned flipping device. Driven by the flipping device, the screen assembly 20 can flip smoothly.

[0064] In this embodiment, the slider 121 can be connected to the screen assembly 20 via a rotating shaft. Specifically, the left side wall of the screen assembly 20 along its length is rotatably connected to the left slider 121 via a rotating shaft, and the right side wall of the screen assembly 20 along its length is rotatably connected to the right slider 121 via a rotating shaft.

[0065] In this embodiment, both the mounting base 11 and the screen assembly 20 can be rectangular. The screen assembly 20 is mounted within the mounting base 11 in a composite movable manner, meaning that the screen assembly 20 can simultaneously perform two movements relative to the mounting base 11: On one hand, the screen assembly 20 can slide linearly along the width direction of the mounting base 11 (i.e., the direction corresponding to the shorter side of the mounting base 11), achieving a translational position 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 around a preset portion in the width direction of the mounting base 11 (for example, the top, middle, or bottom portion of the mounting base 11 in the width direction) as a fulcrum, while the other end of the screen assembly 20 in the width direction flips away from the mounting base 11 to adjust the screen angle. These two movements do not interfere with each other and can be performed simultaneously. For example, while sliding to adjust the position of the screen assembly 20 along its width direction, flipping the screen assembly 20 away from the mounting base 11 to change the viewing angle can greatly improve the flexibility and ease of use of the screen assembly 20 after installation.

[0066] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0067] It should be understood that the above-described embodiments are merely exemplary and not restrictive. Without departing from the basic principles of this utility model, any obvious or equivalent modifications or substitutions made by those skilled in the art regarding the above details will be included within the scope of the claims of this utility model.
