Detailed Implementation

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0020] Please see Figures 1 to 11 The flexible screen lifting device according to one embodiment of the present invention includes a support component 10, a lifting component 20 slidably connected to the support component 10, and a power component 30 installed on the support component 10; the power component 30 is connected to the lifting component 20 to drive the lifting component 20 to perform lifting movements.

[0021] The support assembly 10 includes a base 11, columns 12 connected to opposite ends of one side of the base 11, guide rods 13 respectively connected to each column 12, end plates 14 installed at opposite ends of the base 11, and a base shell 15 covering the base 11. Figures 3 to 5 As shown, the plane of the base 11 and the plane of the column 12 form an angle to change the movement trajectory of the lifting assembly 20.

[0022] Please refer to it again. Figure 5 Each end plate 14 has a groove 16 along its contour edge on its inner surface. The groove 16 is used to slide and connect the lifting assembly 20, providing guidance for the movement of the lifting assembly 20. In this embodiment, the groove 16 includes a straight segment 161 extending along the length of the end plate 14 and a bent segment 162 extending upward from one end of the straight segment 161. By connecting the straight segment 161 and the bent segment 162, the movement direction of the lifting assembly 20 can be switched.

[0023] The lifting assembly 20 includes a base plate 21 slidably connected between two end plates 14, a first nut 22 connected to the middle of the base plate 21, a chain plate 23 connected to one side of the base plate 21, a carrier plate 24 connected to the side of the chain plate 23 away from the base plate 21, a guide plate 25 installed on the back of the carrier plate 24, a second nut 26 installed in the middle of the guide plate 25, and a cover 27 covering the guide plate 25; the cover 27 is slidably inserted through the top of the base shell 15 so as to rise and fall synchronously with the carrier plate 24.

[0024] It should be noted that the carrier plate 24 and the chain plate 23 together constitute the supporting structure of the flexible screen, used to support and connect the flexible screen. The flexible screen is located on the side of the carrier plate 24 facing away from the guide plate 25. Figure 1 As shown, the portion of the flexible screen exposed outside the base housing 15 constitutes the screen display area, the area of ​​which changes with the lifting and lowering movement of the lifting assembly 20.

[0025] In this embodiment, the opposite ends of the base plate 21 and the opposite ends of the chain plate 23 are slidably embedded in the interior of the slide groove 16, and the opposite ends of the guide plate 25 are respectively slidably connected to the guide rod 13. According to actual needs, the base plate 21 and the chain plate 23 are driven to move along the slide groove 16 by the power component 30, thereby driving the flexible screen to rise and fall, to achieve the purpose of expanding or shrinking the screen display area. The column 12 is used to abut against the chain plate 23 and the carrier plate 24. The carrier plate 24, in conjunction with the column 12, provides support for the flexible screen and prevents it from collapsing under stress.

[0026] Specifically, during the movement of the lifting component 20, the chain plate 23 switches its direction of movement along the slide 16 between the straight section 161 and the turning section 162, thereby driving the flexible screen to complete the bending action and realizing the transformation of the flexible screen's shape.

[0027] Furthermore, to improve the smoothness of the movement of the base plate 21 and the chain plate 23 within the slide groove 16, pulleys 28 are installed at both ends of the base plate 21 and both ends of the chain plate 23. The rolling cooperation between the pulleys 28 and the slide groove 16 reduces the frictional resistance during movement.

[0028] In this embodiment, damping sleeves 29 are respectively installed inside the guide plate 25 at opposite ends. The damping sleeves 29 and the guide rods 13 are connected in a sliding sleeve manner. The damping sleeves 29 can reduce the fit gap between the guide plate 24 and the guide rods, reduce the amount of shaking when the lifting assembly 20 moves, and thus significantly reduce the noise generated during the sliding process.

[0029] In this embodiment, the guide plate 25 has through holes at its opposite ends for accommodating the damping sleeve 29. Specifically, as shown... Figure 7 and Figure 8As shown, the damping sleeve 29 includes two arc-shaped clamping pieces 291 arranged in a mirror image, springs 292 respectively fixedly connected to the outer side of each arc-shaped clamping piece 291, and adjusting bolts 293 for abutting the end of the springs 292 away from the arc-shaped clamping pieces 291. The two arc-shaped clamping pieces 291 are located inside the through hole, and are used to clamp the guide rod 13 between them. The adjusting bolts 293 are screwed to the guide plate 25, and the adjusting bolts 25 are located on opposite sides of the through hole. By turning the adjusting bolts 25, the springs 292 can be driven to compress the arc-shaped clamping pieces 291, thereby controlling the clamping force of the arc-shaped clamping pieces 291 on the guide rod 13. This reduces the clearance between the guide plate 24 and the guide rod, reduces the amount of swaying during the movement of the lifting assembly 20, and thus significantly reduces the noise generated during sliding.

[0030] The power assembly 30 includes a gearbox 31 mounted on the base 10, a power motor 32 connected to one side of the gearbox 31, and two lead screws 33 connected to both sides of the gearbox 31. The axis directions of the two lead screws 33 are at an angle, with one lead screw 33 matched and connected to a first nut 22 and the other lead screw 33 matched and connected to a second nut 26. The power motor 32 drives the two lead screws 33 to rotate synchronously through the gearbox 31, thereby driving the base plate 21 and the chain plate 23 to move along the slide groove 16, realizing the lifting and lowering action of the flexible screen. Compared with the traditional driving method, this utility model provides precise motion guidance for the lifting assembly 20 through the slide groove 16, and provides support for the flexible screen with the cooperation of the carrier plate 24 and the column 12. This not only effectively improves the stability of the lifting and lowering action, but also prevents the flexible screen from collapsing due to stress, thus overcoming the defects existing in traditional flexible screen lifting devices.

[0031] Please refer to it again. Figures 9 to 11 The gearbox 31 includes a housing 311, a worm gear 312 rotatably mounted inside the housing 311, a driven wheel 313 coaxially connected to one end of the worm gear 312, two worm wheels 314 matched and connected to both sides of the worm gear 312, cover plates 315 respectively disposed on the outside of each worm wheel 314, and a wave-shaped washer 316 sandwiched between the worm wheel 314 and the cover plate 315. The worm wheels 314 and the lead screw 33 are coaxially connected in a one-to-one correspondence. The rotor of the power motor 32 meshes with the driven wheel 313 through the driving wheel 320 to achieve the transmission connection between the power motor 32 and the lead screw 33. It should be noted that in this embodiment, the surfaces of the worm gear 312, the driven wheel 313, the two worm wheels 314, and the driving wheel 320 are all provided with toothed structures (not shown in the attached drawings) to meet the meshing transmission requirements.

[0032] like Figure 9As shown, the housing 311 has receiving cavities 317 on both sides, which are used to house the worm gear 34. The cover plate 315 covers the receiving cavities 317. At this time, the wave-shaped gasket 316 is sandwiched between the worm gear 314 and the cover plate 315. It can eliminate the axial clearance of the worm gear 314 through its own elastic deformation, ensuring that the worm gear 314 and the worm 312 always maintain a tight mesh, and avoiding free rotation or jamming during the transmission process.

[0033] The above-mentioned flexible screen lifting device has a simple structure and is easy to use. The power motor 32 drives two lead screws 33 to rotate synchronously through the gearbox 31. The base plate 21 and the chain plate 23 are guided to slide along a preset track by the slide groove 16. At the same time, the carrier plate 24 and the column 12 provide support for the flexible screen. This not only effectively improves the stability of the lifting movement, but also prevents the flexible screen from collapsing under stress, thereby overcoming the defects of traditional flexible screen lifting devices.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
