Description

Technical Field

[0001] The invention belongs to the field of display devices, and in particular relates to a display device that can be lifted and lowered by rotating. Background Art

[0002] Currently in the market, the rotating structure and lifting structure of the display 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, it is urgent to develop a rotating lifting mechanism that combines high performance and innovative movement mode. In addition, the current application rate of the zoom line tensioning mechanism inside the bracket is relatively low, resulting in the power cord, data cable, etc. being easily worn during the stretching and shortening process when adjusting the height of the display. When there are many parts inside the bracket, especially the bracket that integrates the rotating structure and the lifting structure, the cables are not convenient to arrange and are easily entangled with each other, which greatly increases the failure rate of the product.

[0003] The Chinese invention patent application with the publication number "CN118654201A" discloses a free screen assembly structure and its free screen. When the screen rotates, the trapezoidal inclined surface block at the end of the wheel frame strip is forced to press toward the straight slot through the inclined surface extrusion block, thereby increasing the clamping force of the two rows of rubber wheels on the display screen; through the design of the locking gear and the rack, the weight of the counterweight slide is transmitted to the pressure block, and then when the wheel frame strip is pressed toward the straight slot through the inclined surface extrusion block, the locking gear and the rack can be meshed and locked. However, the application does not integrate the rotating structure and the lifting structure of the display together.

[0004] The Chinese invention patent with the announcement number "CN118482304B" discloses a computer display support structure, in which the inner wall of the housing is rotatably connected with a rotating shaft, and the surface of the rotating shaft is fixedly sleeved with a gear, the number of which is two, and the gears are meshed with the tooth grooves. By setting the rotating shaft, the gears can be rotated on the inner wall of the housing, and when the support rod moves down, the tooth grooves on its surface mesh with the gears, so the gears will be driven to rotate on the surface of the rotating shaft. However, this invention only involves the rotating structure of the display, and does not combine it with the lifting structure of the display. Summary of the invention

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, and then the second gear 27 drives the semicircular tooth 271 to rotate counterclockwise. When the semicircular tooth 271 rotates counterclockwise, it will mesh with the first rack 21, and gradually rise along the first rack 21 as it rotates, driving the first gear 26 connected to its connecting rod 28 to rise together, and finally realizing that the display 200 and the rotating bracket 400 are rising while rotating. When the semicircular teeth 271 are meshed with the first rack 21 , the display 200 can be lowered until it is reset by simply rotating the display 200 counterclockwise.

[0045] 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 mesh with the second rack 22, and finally the display 200 and the rotating bracket 400 will rise while rotating.

[0046] 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 required to meet the height adjustment requirement of the display 200 .

[0047] Preferably, the rotating lifting mechanism 101 also includes a front cover 13; a first through hole is formed in the side wall of the front cover 13 for allowing the rotating shaft 11 to pass through; both ends of the front cover 13 are slidingly connected to the first slide rail 16 and the second slide rail 18 respectively; 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.

[0049] Furthermore, when the display 200 rotates to drive the first gear 26 and the second gear 27 to rise, the front cover 13 also rises together.

[0050] Preferably, the rotary lifting mechanism 101 also 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 in sequence, and is connected to the rotating shaft 11.

[0052] 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 limiting grooves matching the limiting protrusions are provided on the first slide rail 16 and the second slide rail 18.

[0053] 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 .

[0054] 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 .

[0055] 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 .

[0056] Preferably, the rotary lifting mechanism 101 further includes a fourth gasket 25 , and the fourth gasket 25 is disposed between the limiting member 24 and the second gear 27 .

[0057] Preferably, the rotary lifting mechanism 101 also includes a limit member 24; the limit plate 23 is provided with a limit groove matching 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 arc of the arc groove is the same as the arc 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.

[0058] Furthermore, when the display 200 rotates clockwise, the first gear 26 will be driven by the rotating shaft 11 to rotate clockwise as well. At this time, the limiting member 24 will also move in the clockwise direction in the arc groove. When the limiting member 24 moves until it contacts the end of the arc groove, the display 200 will be limited and cannot continue to rotate clockwise, thereby realizing the limitation of the movement of the display 200 by the limiting member 24.

[0059] Preferably, a first top plate 19 is disposed at one end of the first slide rail 16 facing away from the base 300 ; a second top plate 20 is disposed 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.

[0060] Specifically, the limiting member 24 of this embodiment is a limiting ball.

[0061] 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 and lowering operation of the display 200, but also show a certain novelty in the lifting and lowering 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.

[0062] The rotating and lifting mechanism 101 of this embodiment integrates the rotating 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 output two different dimensional motion forms at the same time by only inputting force in a single direction.

[0063] 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 will overcome the friction force and drive the first gear 26 to rotate. The first gear 26 rotates the connecting rod 28 through the friction force, and the connecting rod 28 then drives the semicircular gear 271 to mesh with the first rack 21 or the second rack 22. At the same time, since the first gear 26 and the second gear 27 are meshed with each other, the first gear 26 can drive the second gear 27 to rotate, and the second gear 27 will also rise relatively and bring the entire display 200 up together. When the second gear 27 rotates ninety degrees, the meshing of the semicircular gear 271 and the rack is completed, and the rising process ends. Since the semicircular gear 271 is equipped with racks in both rotation directions, the rising function can be achieved regardless of whether the display 200 is rotated clockwise or counterclockwise; and to achieve the descent, it is only necessary to rotate the display 200 in the opposite direction.

[0064] Embodiment 2

[0065] like Figures 7 to 9 As shown, the bracket 100 of the display device of this embodiment includes a zoom line tensioning mechanism 102; the zoom line tensioning mechanism 102 includes a fixed plate 1, a positioning plate 9, a zoom line 6, and a plurality of sliders 4; the fixed plate 1 is fixed to the side of the front cover 13 facing away from the rotating bracket 400; a slider 4 is provided at each of the four diagonal positions of the side wall of the fixed plate 1 facing away from the front cover 13, and a positioning plate 9 is also provided on the fixed plate 1; one end of the zoom line 6 is fixedly installed in the base 300; the other end of the zoom line 6 is successively wrapped around each slider 4 and fixedly connected to the positioning plate 9.

[0066] Preferably, each slider 4 includes a winding end and an elastic end, the winding end of each slider 4 is oriented toward the diagonal point on the side wall of the fixed plate 1 closest to it, and the elastic end of each slider 4 is oriented toward the center of the side wall of the fixed plate 1; a scaling wire 6 is wound around the winding end of each slider 4.

[0067] Preferably, each slider 4 also includes a sliding member 2; the sliding member 2 is located inside the slider 4; each slider 4 is slidably connected to the side wall of the fixed plate 1 through the sliding member 2; one end of the sliding member 2 contacts the side wall of the fixed plate 1, and the other end of the sliding member 2 contacts the inner wall of the slider 4.

[0068] Preferably, each slider 4 also includes a spring 3; a slot is provided at the elastic end of each slider 4; outside each slot, one end of a spring 3 is fixed to the side wall of the fixed plate 1, and the other end of the spring 3 is located in the slot adjacent to it and contacts the corresponding slider 4.

[0069] Preferably, the scaling line tensioning mechanism 102 also includes a winding post 8; the slider 4 includes a first slider 4, a second slider 4, a third slider 4, and a fourth slider 4; the first slider 4 is located at the upper left corner of the side wall of the fixed plate 1; the second slider 4 is located at the upper right corner of the side wall of the fixed plate 1; the third slider 4 is located at the lower left corner of the side wall of the fixed plate 1; the fourth slider 4 is located at the lower right corner of the side wall of the fixed plate 1; the winding post 8 is located between the second slider 4 and the fourth slider 4; the positioning plate 9 is located between the second slider 4 and the center of the side wall of the fixed plate 1.

[0070] Preferably, the other end of the zoom wire 6 is wound around the winding post 8 , the fourth slider 4 , the third slider 4 , the second slider 4 , and the first slider 4 in sequence, and then fixedly installed in the positioning plate 9 .

[0071] Preferably, the zoom wire tightening mechanism 102 further includes a first screw 5 ; the winding post 8 is fixed to the side wall of the fixing plate 1 via the first screw 5 .

[0072] Preferably, the zoom line tensioning mechanism 102 further includes a second screw 7 ; the positioning plate 9 is fixed to the side wall of the fixing plate 1 by the second screw 7 .

[0073] Specifically, when the display 200 rotates and rises, the front cover 13 will drive the fixed plate 1 to rise together. At this time, the zoom line 6 will be pulled by force. At this time, since the slider 4 and the fixed plate are slidably connected, the pulled zoom line 6 will be tightened, driving the four sliders 4 to move toward the center of the fixed plate 1 and causing the slider 4 to compress the spring 3. The elastic force of the spring 3 increases, so that the elastic end of the slider 4 will also support the tightened zoom line 6.

[0074] Furthermore, when the display 200 rotates in the opposite direction and descends, the front cover 13 will drive the fixed plate 1 to descend together. At this time, the zoom line 6 will expand, reducing the pressure on the slider 4, and then the spring 3 will rebound the slider 4, causing the slider 4 to move back, and the slider 4 moving back will also support the expanded zoom line 6.

[0075] The display device of this embodiment realizes the tightening and expanding functions of the cable through the zoom wire tensioning mechanism 102 and the spring 3. The design of winding the wire at multiple corners can keep the cable in a taut state to the greatest extent. The back-and-forth movement of the four sliders 4 increases the maximum elastic deformation of the cable contraction and release. When the display 200 rotates and rises, it will encounter a certain resistance, so that the rotation and rising speed of the display 200 is limited, which can improve the stability of the rotation and rising of the display 200, and maintain the balance between the display 200 and the bracket 100, preventing the display 200 from being installed unstably due to the gravity of the display 200. In addition, this winding method can reduce the wear rate of the wire and increase the service life of the device.

[0076] The above is a detailed description of an embodiment of a display device for lifting and lowering by rotation provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention, and 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, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
