Description

Technical Field

[0001] The utility model belongs to the technical field of display devices, and particularly relates to a rotating lifting mechanism of a column and a display device. Background Art

[0002] Currently, on the market, the rotating structure and lifting structure of monitors are generally independent of each other. Since the current technical level of integrating these two functions is not high enough, even if the functions are integrated, the operating efficiency cannot be significantly improved. Therefore, there is an urgent need to develop a rotating and lifting mechanism that combines high performance and innovative movement modes.

[0003] Chinese invention patent application publication number "CN118654201A" discloses a free-screen assembly structure and its free-screen. When the screen rotates, a ramped extrusion block forcibly presses the trapezoidal ramped block at the end of the wheel frame strip toward the straight slot, thereby increasing the clamping force of the two rows of rubber wheels on the display screen. A locking gear and rack design transmits the weight of the counterweight slider to the pressure block. Then, when the ramped extrusion block presses the wheel frame strip toward the straight slot, the locking gear and rack engage and lock. However, this application does not integrate the display's rotating and lifting mechanisms.

[0004] Chinese invention patent publication number "CN118482304B" discloses a computer display support structure. A rotating shaft is rotatably connected to the inner wall of the housing. Two gears are fixedly mounted on the surface of the shaft. These gears mesh with tooth grooves. The shaft allows the gears to rotate on the inner wall of the housing. When the support rod moves downward, the tooth grooves on its surface mesh with the gears, driving the gears to rotate on the surface of the shaft. However, this invention only addresses the display's rotating structure and does not integrate it with the display's lifting mechanism. Utility Model Content

[0037] like Figures 4-6 As shown, the column 100 includes a rotating lifting mechanism 101; the rotating bracket 400 is hinged to the column 100 through the rotating lifting mechanism 101; the rotating lifting mechanism 101 includes a rotating shaft 11, a first gear 26, a second gear 27, and a connecting rod 28; one end of the rotating shaft 11 is fixedly connected to the center of one side of the first gear 26, and the other end of the rotating shaft 11 is fixedly connected to the other side of the rotating bracket 400; a first connection point is provided at the center of the other side of the first gear 26; a first sawtooth is provided on the outer periphery of the first gear 26; the second gear 27 is fixedly connected to the connecting rod 28; A second serration is provided on the outer periphery; the second serration is meshed with the first serration; a semicircular tooth 271 is fixedly provided on the side of the second gear 27 facing away from the rotating bracket 400; the size of the semicircular tooth 271 is larger than the size of the second gear 27, and the top of the semicircular tooth 271 is located below the first connection point; a second connection point is provided on the side of the semicircular tooth 271 facing away from the second gear 27; one end of the connecting rod 28 is movably connected to the first connection point, and the other end of the connecting rod 28 is movably connected to the second connection point; the slide rail assembly is provided on the outside of both sides of the semicircular tooth 271.

[0039] Specifically, in the initial state of the display 200, the center of the semicircular tooth 271 is at the lowest point. At this time, the semicircular tooth 271 is not in contact with the first rack 21 or the second rack 22, and the display 200 is at its lowest position. When the display 200 begins to rotate clockwise, it drives the rotating bracket 400 and the rotating shaft 11 to rotate clockwise. At this time, the first gear 26 is driven by the rotating shaft 11 to rotate clockwise, and the first gear 26 drives the second gear 27 to rotate counterclockwise. In turn, the second gear 27 drives the semicircular tooth 271 to rotate counterclockwise.

When the semicircular teeth 271 are engaged with the first rack 21 , the display 200 can be lowered to its original position by simply rotating the display 200 counterclockwise.

[0040] Furthermore, when the display 200 is reset to the initial state, if the display 200 rotates counterclockwise, the semicircular teeth 271 will rotate clockwise and engage with the second rack 22, and finally the display 200 and the rotating bracket 400 will rise while rotating.

[0041] Furthermore, the length of the racks provided on the two slide rails determines the maximum lifting height of the display 200 , and the length of the racks can be set as needed to meet the height adjustment requirements of the display 200 .

[0042] Preferably, the rotating lifting mechanism 101 also includes a front cover 13; the side wall of the front cover 13 is provided with a first through hole for allowing the rotating shaft 11 to pass through; the two ends of the front cover 13 are respectively slidably connected to the first slide rail 16 and the second slide rail 18; the first gear 26 and the second gear 27 are both located on the side of the front cover 13 facing away from the rotating bracket 400.

[0043] Preferably, the rotary lifting mechanism 101 also includes a first connecting member 14 and a second connecting member 29; the front cover 13 is provided with a second through hole that matches the position of the center of the second gear 27; the position of the second connecting point also matches the position of the center of the second gear 27; the first connecting member 14 starts from the side of the front cover 13 facing away from the second gear 27, and passes through the second through hole, the center of the second gear 27, the second connecting point, and the other end of the connecting rod 28 in sequence, and is fixedly connected to the second connecting member 29 located on the side of the connecting rod 28 facing away from the semicircular tooth 271.

[0044] Furthermore, when the display 200 rotates and drives the first gear 26 and the second gear 27 to rise, the front cover 13 also rises together.

[0045] Preferably, the rotary lifting mechanism 101 further includes a third connecting member 30 ; the third connecting member 30 starts from the side of the connecting rod 28 facing away from the first gear 26 , passes through one end of the connecting rod 28 , the center of the first gear 26 , the first through hole, and is connected to the rotating shaft 11 .

[0046] Preferably, the rotary lifting mechanism 101 also includes a limit plate 23; one end of the limit plate 23 is provided with a third through hole matching the position of the first through hole; one end of the limit plate 23 is provided between the rotating shaft 11 and the first gear 26 through the third through hole; the other end of the limit plate 23 is provided with a fourth through hole matching the position of the second through hole; the other end of the limit plate 23 is provided between the front cover 13 and the second gear 27 through the fourth through hole.

[0047] Preferably, the limiting plate 23 is located between the first slide rail 16 and the second slide rail 18; limiting protrusions are provided on both sides of the other end of the limiting plate 23; and the first slide rail 16 and the second slide rail 18 are both provided with limiting grooves matching the limiting protrusions.

[0048] Preferably, the rotary lifting mechanism 101 further includes a first gasket 12 ; the first gasket 12 is disposed between the rotating shaft 11 and the front cover 13 .

[0049] Preferably, the rotary lifting mechanism 101 further includes a second gasket 15 ; the second gasket 15 is disposed between the rotating shaft 11 and the limiting plate 23 .

[0050] Preferably, the rotary lifting mechanism 101 further includes a third gasket 17 ; the third gasket 17 is disposed between the limiting plate 23 and the first gear 26 .

[0051] Preferably, the rotary lifting mechanism 101 further includes a fourth gasket 25 , which is disposed between the limiting member 24 and the second gear 27 .

[0052] Preferably, the rotary lifting mechanism 101 also includes a limit member 24; the limit plate 23 is provided with a limit groove that matches the size of the limit member 24; one end of the limit member 24 is located in the limit groove; the first gear 26 is provided with an arc groove on the side facing the limit plate 23; the curvature of the arc groove is the same as the curvature of the first gear 26, and the distance from the arc groove to the center of the first gear 26 is smaller than the radius of the first gear 26; the other end of the limit member 24 is located in the arc groove.

[0053] Furthermore, when the display 200 rotates clockwise, the first gear 26 will be driven by the rotating shaft 11 to rotate clockwise together. At this time, the limit member 24 will also move in the clockwise direction in the arc groove. When the limit member 24 moves until it contacts the end of the arc groove, the display 200 will be limited and can no longer rotate clockwise, thereby realizing the limitation of the movement of the display 200 by the limit member 24.

[0054] Preferably, a first top plate 19 is provided at one end of the first slide rail 16 facing away from the base 300 ; a second top plate 20 is provided at one end of the second slide rail 18 facing away from the base 300 ; and the first top plate 19 and the second top plate 20 are connected.

[0055] Specifically, the limiting member 24 of this embodiment is a limiting ball.

[0056] The rotary lifting mechanism 101 of this embodiment adopts a gear rack meshing transmission method and is limited by a limiting ball. It can not only significantly improve the efficiency of the lifting operation of the display 200, but also show a certain novelty in the lifting process of the display 200, so as to fully meet the personalized needs of diversified user groups and bring users a more convenient and efficient use experience.

[0057] The rotating and lifting mechanism 101 of this embodiment integrates the rotation and lifting structures of the display 200, realizing a new structure with a flexible transmission method, which can fully adapt to the diverse needs of customers in different environments, and can simultaneously output two different dimensions of motion by only inputting force in a single direction.

[0058] The display device of this embodiment is provided with the rotating lifting mechanism 101. When the display 200 is subjected to an external force and has a tendency to rotate, the display 200 overcomes the friction and drives the first gear 26 to rotate. The first gear 26, through the friction, rotates the connecting rod 28, which in turn drives the semicircular teeth 271 to engage with the first rack 21 or the second rack 22. At the same time, due to the mutual engagement between the first gear 26 and the second gear 27, the first gear 26 can drive the second gear 27 to rotate, and the second gear 27 will also rise relative to the first rack 21 or the second rack 22. When the second gear 27 rotates 90 degrees, the meshing of the semicircular teeth 271 and the rack is complete, and the lifting process ends. Because the semicircular teeth 271 are equipped with racks in both rotational directions, the lifting function can be achieved whether the display 200 is rotated clockwise or counterclockwise; to achieve the lowering function, the display 200 only needs to be rotated in the opposite direction.

[0059] The above is a detailed description of an embodiment of a column rotation and lifting mechanism and a display device provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
