[0002] Currently, with the widespread application of large-screen touchscreen smart products, users have raised diverse demands regarding the overall appearance, rotatability, and portability of these products, placing more stringent requirements on their structural design. Current large-screen touchscreen smart products can achieve basic rotatability. These products consist of a single integrated structure of the body and display screen, with a rotating mechanism supporting the rotation. However, this rotating mechanism must bear the weight of the entire device. When the size of the large-screen touchscreen smart product is large, the rotating mechanism struggles to support the weight, resulting in poor rotation reliability. Utility Model Content

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] The directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for explanation and understanding of this invention, and not for limiting it. Furthermore, in the accompanying drawings, structures that are similar or identical are indicated by the same reference numerals.

[0039] Reference Figures 1 to 14 , please refer to Figure 1 and Figure 2 This invention illustrates an embodiment of the rotatable display device provided by this utility model. The structure and working principle of the rotatable display device are described in detail below with reference to the accompanying drawings. The rotatable display device includes: a support frame 10; a body 20 disposed on the support frame 10; a display screen 30 connected to the body 20 for display; and a rotating mechanism 40, including a mounting plate 41 and a rotating assembly 42. The rotating assembly 42 is disposed on one side of the body 20, the mounting plate 41 is disposed on the rotating assembly 42, and the display screen 30 is disposed on the mounting plate 41. The mounting plate 41, in conjunction with the rotating assembly 42, is rotatably connected to the body 20 to drive the display screen 30 to rotate relative to the body 20.

[0040] In practice, the rotatable display device consists of a support frame 10, a body 20, a display screen 30, and a rotating mechanism 40. The body 20 is mounted on the support frame 10, forming an integral structure with it. The support frame 10 primarily provides support, holding the body 20 at a corresponding height. The display screen 30 is connected to the body 20 via signal lines. The body 20 and the display screen 30 work together to achieve the display function. The body 20 houses a control board and various circuits. The display screen 30 is connected to the control board and various circuits inside the body 20 via signal lines for display purposes. The rotating mechanism 40 is the main structure for rotating the display screen 30. The rotating mechanism 40 consists of a mounting plate 41 and a rotating component 42. The rotating component 42 is located on one side of the body 20, specifically connected to one side of the body 20 in the horizontal direction. Mounting plate 41 is a plate-like structure, typically designed as a square or round plate. Mounting plate 41 is mounted on the rotating assembly and is primarily used to mount the display screen 30. Specifically, the display screen 30 is fixed to mounting plate 41, forming an integral structure with it. Mounting plate 41, in conjunction with rotating assembly 42, is rotatably connected to the body 20. That is, mounting plate 41 can rotate relative to body 20 through its cooperation with rotating assembly 42, with any rotation angle. The display screen 30 is mounted on mounting plate 41, forming an integral structure with it. Mounting plate 41 rotates relative to body 20 in conjunction with rotating assembly 42, thereby causing the display screen 30 to rotate relative to body 20 as well, achieving rotation of the display screen 30 at corresponding angles. In practical applications, users can adjust the rotation angle of the display screen 30 according to the usage scenario requirements, rotating the display screen 30 to a direction that meets the user's needs for display. During the rotation, the display screen 30 and the support frame 10 are an integral structure and remain stationary, while the mounting plate 41 is an integral structure with the display screen 30, independent of the main body 20. The display screen 30 and the mounting plate 41 rotate together relative to the main body 20 and the support frame 10. The weight of the main body 20 is directly borne by the support frame 10, and the main body 20 directly provides counterweight to the support frame 10. The overall center of gravity of the device falls on the support frame 10, while the weight of the display screen 30 is directly borne by the rotating mechanism 40, which consists of the mounting plate 41 and the rotating component 42. The rotating mechanism 40 does not need to bear the weight of the main body 20. The stability of the large-size display screen 30 rotation is improved, making it safer and more reliable for users. At the same time, the separation of the display screen 30 from the main body 20 not only meets the requirement of device rotation but also greatly increases the consistency and aesthetics of the device.

[0041] In this embodiment, the main body is mounted on a support frame, and the display screen is mounted on a mounting plate. The mounting plate is connected to the main body by a rotating component. The display screen is independent of the main body, and the weight of the main body is borne by the support frame. The rotating mechanism only needs to bear the weight of the display screen. This improves the stability and reliability of the rotation of the large-size display screen.

[0042] In one embodiment, reference is made to Figures 3 to 8 The rotating assembly 42 includes a first connecting plate 421 and a second connecting plate 422. The first connecting plate 421 is fixed to one side of the body 20. A circular opening 401 is provided on the mounting plate 41. An annular protrusion 4201 is provided on one side of the first connecting plate 421. The annular protrusion 4201 passes through the circular opening 401 and is fixed to the second connecting plate 422. The mounting plate 41 is located between the first connecting plate 421 and the second connecting plate 422 and can rotate around the annular protrusion 4201. In a specific implementation, the rotating assembly 42 includes a first connecting plate 421 and a second connecting plate 422. Both the first connecting plate 421 and the second connecting plate 422 are designed as disc-shaped structures. The first connecting plate 421 is fixed to one side of the body 20 in the horizontal direction by bolts. A circular opening 401 is provided in the center of the mounting plate 41, and the circular opening 401 extends through the front and rear sides of the mounting plate 41. An annular protrusion 4201 is provided on one side of the first connecting plate 421. The annular protrusion 4201 is annular in shape and protrudes a certain distance from one side of the first connecting plate 421. The diameter of the annular protrusion 4201 is slightly smaller than the diameter of the circular opening 401. The annular protrusion 4201 passes through the circular opening 401 on the mounting plate 41 and is connected and fixed to the second connecting plate 422. The mounting plate 41 is located between the first connecting plate 421 and the second connecting plate 422. The first connecting plate 421 and the second connecting plate 422 form front and rear stops for the mounting plate 41. Through the cooperation of the circular opening 401 and the annular protrusion 4201, the mounting plate 41 can rotate around the annular protrusion 4201. Thus, the mounting plate 41 can rotate relative to the first connecting plate 421 and the second connecting plate 422, thereby driving the display screen 30 to rotate. The display screen 30 has high rotational stability and is very convenient to rotate.

[0043] Furthermore, referring to Figure 5 and Figure 8The rotating assembly 42 further includes a limiting bolt 423. The mounting plate 41 is provided with an arc-shaped threaded hole 402, which is located on the periphery of the circular opening 401 and extends circumferentially in the circular opening 401. The first connecting disc 421 is provided with a limiting screw hole 403 on the side facing the mounting plate 41. The limiting screw hole 403 is exposed in the arc-shaped threaded hole 402. The limiting bolt 423 passes through the arc-shaped threaded hole 402 and is threadedly connected to the limiting screw hole 403. When the mounting plate 41 rotates by a certain angle, the limiting bolt 423 stops at the end of the arc-shaped threaded hole 402. In specific implementation, the rotating assembly 42 also includes a limiting bolt 423. The limiting bolt 423 has a certain length and an arc-shaped threaded hole 402 is provided on the mounting plate 41. The arc-shaped threaded hole 402 is specifically an arc-shaped through hole structure on the mounting plate 41, located on the periphery of the circular opening 401 and extending a certain length in the circumferential direction of the circular opening 401. The width between the inner and outer arc edges of the arc-shaped threaded hole 402 is greater than the diameter of the limiting bolt 423. A limiting screw hole 403 is provided on the side of the first connecting plate 421 facing the mounting plate 41. The limiting screw hole 403 is exposed in the arc-shaped threaded hole 402. The limiting screw hole 403 is adapted to the size of the limiting bolt 423. The limiting bolt 423 passes through the arc-shaped threaded hole 402 and is threadedly connected to the limiting screw hole 403. One or more arc-shaped threaded holes 402 can be provided. Usually, two symmetrical arc-shaped threaded holes 402 are provided on both sides of the circular opening 401. When the mounting plate 41 rotates, the limiting bolt 423 remains stationary connected to the first connecting plate 421, while the arc-shaped toothed hole 402 adjusts its position along the arc direction, causing the position of the limiting bolt 423 within the arc-shaped toothed hole 402 to change. When the mounting plate 41 rotates to a certain angle in a certain direction, the limiting bolt 423 stops at the end of the arc-shaped toothed hole 402 in that corresponding direction. The mounting plate 41 is blocked by the limiting bolt 423 and cannot continue to rotate in that direction. Overall, the rotation angle of the mounting plate 41 is limited to the arc range corresponding to the arc of the arc-shaped toothed hole 402, thereby limiting the rotation angle of the display screen 30. The arc of the arc-shaped toothed hole 402 can be designed according to the rotation angle requirements of the display screen 30. In practical applications, the angle of the arc-shaped toothed hole 402 can be set to 90 degrees, allowing the display screen 30 to rotate 90 degrees, thus enabling horizontal and vertical adjustments to the display screen 30, which is very convenient to use.

[0044] Furthermore, referring to Figure 8 and Figure 9The rotating assembly 42 further includes a sleeve 424, which is rotatably fitted onto the limiting bolt 423 and passes through the arc-shaped toothed hole 402. In specific implementation, the rotating component 42 includes a sleeve 424. The inner diameter of the sleeve 424 is slightly larger than the diameter of the limiting bolt 423, and the outer diameter is slightly smaller than the width between the inner and outer arc edges of the arc-shaped toothed hole 402. The sleeve 424 is rotatably fitted onto the limiting bolt 423 and passes through the arc-shaped toothed hole 402. The outer wall of the sleeve 424 contacts the inner and outer arc edges of the arc-shaped toothed hole 402. When the mounting plate 41 rotates, the outer wall of the sleeve 424 contacts and engages with the inner and outer arc edges of the arc-shaped toothed hole 402, causing the sleeve 424 to rotate relative to the limiting bolt 423. The engagement of the sleeve 424, the limiting bolt 423, and the arc-shaped toothed hole 402 can assist the mounting plate 41 in rotating. While limiting the mounting plate 41, it assists the mounting plate 41 in rotating, making the rotation of the mounting plate 41 more stable and the rotation of the display screen 30 more stable and reliable.

[0045] In one embodiment, reference is made to Figure 3 and Figure 4 The rotating mechanism 40 further includes a locking assembly 43. An annular wear-resistant plate 410 is provided on the side of the mounting plate 41 facing the first connecting disk 421. The annular wear-resistant plate 410 is located outside the circular opening 401. The locking assembly 43 is located on the first connecting disk 421 and abuts against the annular wear-resistant plate 410. The locking assembly 43 is used to elastically press against the annular wear-resistant plate 410 to increase the resistance to rotation of the mounting plate 41. In a specific implementation, the rotating mechanism 40 further includes the locking assembly 43. An annular wear-resistant plate 410 is provided on the side of the mounting plate 41 facing the first connecting disk 421. The annular wear-resistant plate 410 is designed as a ring and is made of wear-resistant material, so that it will not wear down significantly even after prolonged friction. The locking assembly 43 is integrally mounted on the first connecting disk 421 and connected to the annular wear-resistant plate 410 on the mounting plate 41. The locking component 43 is used to elastically press against the annular wear-resistant plate 410. By elastically pressing against the annular wear-resistant plate 410, the locking component 43 constantly rubs against the annular wear-resistant plate 410 when the mounting plate 41 rotates. The friction method can be sliding friction or rolling friction. Through the pressing friction of the locking component 43 against the annular wear-resistant plate 410, the resistance to the rotation of the mounting plate 41 increases, so the display screen 30 will not easily rotate. A certain force needs to be applied to rotate the display screen 30. After the user rotates the display screen 30 to a certain position, the display screen 30 is locked at that position, and the mounting plate 41 will not rotate again due to gravity. The display screen 30 can be adjusted in any direction, making it more convenient to use.

[0046] Furthermore, referring to Figure 10and Figure 11 The locking assembly 43 includes a spring 431, a ball bearing 432, and a sealing nut. The first connecting plate 421 has a mounting hole 4202 that leads directly to one side of the mounting plate 41. The ball bearing 432 is located at the end of the mounting hole 4202 near the mounting plate 41, and the sealing nut is located at the end of the mounting hole 4202 away from the mounting plate 41. The spring 431 is compressed in the mounting hole 4202, with one end abutting against the sealing nut and the other end abutting against the ball bearing 432 to push the ball bearing 432 toward the annular wear-resistant plate 410. In a specific implementation, the mounting hole 4202 is provided on the first connecting plate 421, leading directly to one side of the mounting plate 41. The front end of the mounting hole 4202 faces the mounting plate 41, and the rear end faces the machine body 20. The locking assembly 43 mainly consists of a spring 431, a ball bearing 432, and a sealing nut. The ball bearing 432 is a spherical structure designed with a hard material. The diameter of the ball bearing 432 is slightly smaller than the diameter of the mounting hole 4202. The ball bearing 432 is positioned at the end of the mounting hole 4202 closest to the mounting plate 41, i.e., the front end of the mounting hole 4202. The end of the mounting hole 4202 furthest from the mounting plate 41 has a threaded structure, i.e., the rear end of the mounting hole 4202 has a threaded structure. The sealing nut is threadedly connected to the end of the mounting hole 4202 furthest from the mounting plate 41. The sealing nut is used mainly to close the rear end of the mounting hole 4202 and to facilitate the installation of the ball bearing 432 and the spring 431. The spring 431 is compressed and installed in the mounting hole 4202, specifically between the ball 432 and the sealing nut. One end of the spring 431 abuts against the ball 432, and the other end abuts against the sealing nut. The length of the spring 431 before compression is greater than the depth of the mounting hole 4202. The elastic force generated by the compression of the spring 431 pushes the ball 432 toward the annular wear-resistant plate 410 on the mounting plate 41, so that the ball 432 elastically presses against the annular wear-resistant plate 410. When the mounting plate 41 rotates, the ball 432 always falls between the inner and outer circles of the annular wear-resistant plate 410. The annular wear-resistant plate 410 moves relative to the ball 432, causing the ball 432 to roll. The ball 432 cooperates with the annular wear-resistant plate 410 through rolling friction, which not only enables the display screen 30 to be positioned, but also reduces the wear of the annular wear-resistant plate 410 and extends its service life.

[0047] Furthermore, referring to Figure 12The annular wear-resistant plate 410 has multiple positioning holes 4101 along its circumference. The diameter of the positioning holes 4101 is smaller than the diameter of the ball bearing 432. The distances from the positioning holes 4101 and the ball bearing 432 to the center of the circular opening 401 are equal. The mounting plate 41 rotates, causing the ball bearing 432 to move circumferentially along the circular opening 401, allowing the ball bearing 432 to enter or exit the positioning holes 4101. Specifically, the annular wear-resistant plate 410 has multiple positioning holes 4101 along its circumference. The positioning holes 4101 are circular and spaced equally. The diameter of the positioning holes 4101 is smaller than the diameter of the ball bearing 432, preventing the ball bearing 432 from passing through. The distance from the positioning holes 4101 to the center of the circular opening 401 is equal to the distance from the ball bearing 432 to the center of the circular opening 401. In practical applications, when the mounting plate 41 rotates, the annular wear-resistant plate 410 rotates along with the mounting plate 41, causing the position of the positioning hole 4101 on the annular wear-resistant plate 410 to change. When the positioning hole 4101 and the ball 432 are aligned, under the elastic force of the spring 431, the ball 432 is pushed into the corresponding positioning hole 4101, so that part of the ball 432 is in the mounting hole 4202 of the first connecting plate 421, and the other part is embedded in the positioning hole 4101 on the annular wear-resistant plate 410, thereby increasing the rotational resistance of the mounting plate 41. With the ball 432 embedded in the positioning hole 4101, the position of the mounting plate 41 is locked in a fixed position, and the display screen 30 is locked. The display screen 30 is stably held at the corresponding angle and will not be easily rotated. A certain amount of force needs to be applied to rotate the display screen 30 to make the ball 432 disengage from the positioning hole 4101. After the ball bearing 432 disengages from the positioning hole 4101, the mounting plate 41 continues to rotate. The ball bearing 432 rolls along the axial surface of the annular wear-resistant plate 410, allowing the display screen 30 to rotate smoothly together with the mounting plate 41 until the ball bearing 432 re-enters the positioning hole 4101. The mounting plate 41 then locks into another fixed position, and the display screen 30 is locked in place again. By design, when the mounting plate 41 rotates at a certain angle, the ball bearing 432 remains aligned and embedded in the positioning hole 4101, and the position of the mounting plate 41 remains fixed. This ensures that the display screen 30 can be stably maintained at the corresponding angle without being easily rotated, thus achieving automatic correction of the rotation angle of the display screen 30.In the specific design, four equally spaced positioning holes 4101 are usually provided on the annular wear-resistant plate 410. Two sets of locking components 43 are designed on the first connecting plate 421. The positions of the two sets of locking components 43 correspond one-to-one with the two positioning holes 4101 on the annular wear-resistant plate 410 that are on the same radial direction. In this way, every time the mounting plate 41 rotates 90 degrees, the balls 432 of the two sets of locking components 43 are pushed by the elastic force of the spring 431 and respectively embedded into the two positioning holes 4101 on the annular wear-resistant plate 410 that are on the same radial direction. This allows the mounting plate 41 to enter the locking position once every 90 degrees of rotation. The display screen 30 can be locked at 0 degrees and 90 degrees relative to the horizontal plane without easily rotating, which can meet the user's needs for horizontal and vertical display scenarios of the display screen 30.

[0048] In one embodiment, reference is made to Figures 4 to 8 The annular protrusion 4201 has a first threading port 50 on its inner side, and the second connecting plate 422 has a second threading port 51 on its inner side. The first threading port 50, the circular opening 401, and the second threading port 51 are sequentially overlapped and aligned. One side of the body 20 is exposed in the first threading port 50, and one side of the display screen 30 is exposed in the second threading port 51. The body 20 and the display screen 30 are sequentially connected by threading through the first threading port 50, the circular opening 401, and the second threading port 51. In specific implementation, a first wire-passing port 50 is provided on the inner side of the annular protrusion 4201. The first wire-passing port 50 is an opening structure that passes through the front and rear sides of the first connecting plate 421. One side of the body 20 is exposed in the first wire-passing port 50. A second wire-passing port 51 is provided on the inner side of the second connecting plate 422. The second wire-passing port 51 is another opening structure that passes through the front and rear sides of the first connecting plate 421. One side of the display screen 30 is exposed in the second wire-passing port 51. Mounting plate 41 is located between first connecting plate 421 and second connecting plate 422. First cable entry port 50, circular opening 401, and second cable entry port 51 are sequentially overlapped and aligned. The chassis 20 and display screen 30 are connected by cable passing through the first cable entry port 50, circular opening 401, and second cable entry port 51 in sequence. Specifically, the chassis 20 exposes one side of the first cable entry port 50 to lead out the signal cable. The signal cable first passes through the first cable entry port 50, then through the circular opening 401, and finally exits from the second cable entry port 51 to connect to the display screen. The display screen 30 establishes a signal connection between the device body 20 and the display screen 30. The signal cable is reserved with sufficient length so that the display screen 30 will not pull on the signal cable within the rotation angle range. Since the power cable, signal source interface, USB interface, etc. of the device are all located in the device body 20, the device body 20 and the display screen 30 are connected by wires through the first wire through port 50, the circular opening and the second wire through port 51. Therefore, the display screen 30 does not need to be connected by extra wires, which effectively avoids problems such as messy wires and loose plug interfaces when the display screen 30 rotates.

Both the first bipod 11 and the second bipod 12 are connected to the body 20 to jointly support the body 20. In specific implementation, the support frame 10 serves as a support structure, mainly composed of a first bipod 11 and a second bipod 12. The first bipod 11 and the second bipod 12 are identical "Y"-shaped bipod structures, with the first bipod 11 and the second bipod 12 spaced apart. The tops of the first bipod 11 and the second bipod 12 are connected and fixed to the bottom of the body 20, together supporting the body 20 as a whole, raising the body 20 to a certain height off the ground, thus placing the display screen 30 at a suitable height off the ground. Through the support of the first bipod 11 and the second bipod 12, the bipod support structure can maintain the stability of the body 20 and the display screen 30, preventing the display screen 30 from tilting forward or to the side when rotating.

[0050] Furthermore, referring to Figure 1 , Figure 13 as well as Figure 14 The support frame 10 also includes casters 13, which are connected to the ends of the first bipod 11 and the second bipod 12. Specifically, the support frame 10 further includes casters 13, which are roller structures capable of 360-degree free rotation, allowing them to roll freely in any direction. The casters 13 are fixedly connected to the ends of the first bipod 11 and the second bipod 12, with one caster 13 connected to each end of the first bipod 11 and one caster 13 connected to each end of the second bipod 12, for a total of four casters 13. Through the casters 13, the entire device can move in any direction on the ground, making the movement and handling of the device more convenient.
