In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes the implementation of the present invention based on its overall structure.

[0042] This embodiment provides a display screen device, including:

[0043] Display screen 1;

[0044] A connecting portion 2, the connecting portion 2 comprising a connecting body 21 disposed on the back of the display screen 1 and a connecting cover 22 disposed on the back of the connecting body 21;

[0045] a supporting portion 3 , the supporting portion 3 having a supporting back surface 31 facing away from the display screen 1 ;

[0046] The pivot mechanism 4 includes a first pivot portion 41 arranged on the connecting portion 2 and a second pivot portion 42 arranged on the supporting portion 3. A rotating mechanism 43 is provided between the second pivot portion 42 and the first pivot portion 41. The rotating mechanism 43 includes an arc-shaped rotating groove 431 and a rotating shaft 432 limited in the rotating groove 431. The rotation center 433 of the rotating groove 431 is located on the intersection line where the connecting back side 221 of the connecting cover body 22 and the supporting back side 31 intersect.

[0047] By means of the above structure, Figures 1 to 3 As shown, this structure not only allows the support portion 3 to rotate relative to the connecting cover 22, but also allows the connecting back surface 221 of the connecting cover 22 and the supporting back surface 31 to always remain in contact during the rotation process, and can also reduce the thickness of the connecting cover 22 and the supporting portion 3, thereby making the display screen 1 device have a more beautiful and simpler structure.

[0048] Specifically, the display screen 1 may be in the form of a flat panel, and is used to output text, images, videos and other graphic information.

[0049] The connecting portion 2 may include a connecting body 21 and a connecting cover 22. The connecting body 21 may be fixed to the back of the display screen 1 by fasteners. Preferably, the connecting body 21 may rotate relative to the display screen 1 around an axis perpendicular to the display screen 1. The connecting cover 22 may be fixed to the connecting body 21 by a fastening mechanism (such as bolts, screws, etc.) provided on the side, so that it may rotate as the connecting body 21 rotates. When the connecting cover 22 is placed on the connecting body 21, the connecting cover 22 has a connecting back surface 221 facing away from the display screen 1. When an operator or a consumer observes from the back of the display screen 1, the connecting back surface 221 of the connecting portion 2 can be seen.

[0050] The support portion 3 has a support front surface 32 facing the display screen 1 and a support back surface 31 facing away from the display screen 1. When an operator or a consumer observes from the back of the display screen 1, the support back surface 31 of the support portion 3 can be seen.

[0051] The first pivot portion 41 can be fixedly mounted on the connecting body 21 of the connecting portion 2 by means of fasteners. The second pivot portion 42 can be fixedly mounted on the supporting portion 3 by means of fasteners. Preferably, the second pivot portion 42 can be mounted on the supporting front surface 32 of the supporting portion 3. This facilitates installation while concealing the fasteners.

[0052] In this embodiment, if Figure 4 and Figure 5As shown, a circular arc-shaped rotation groove 431 is provided on the first pivot portion 41. A rotation shaft 432 is provided on the second pivot portion 42. As the support portion 3 rotates along with the rotation portion, the rotation shaft 432 can move relative to the rotation groove 431. Since the rotation center 433 of the rotation groove 431 is located on the intersection line where the connection back surface 221 of the connection cover 22 and the support back surface 31 intersect, the rotation center 433 between the connection back surface 221 and the support back surface 31 coincides with the rotation center 433 of the rotation groove 431.

[0053] Of course, in another optional embodiment, the arc-shaped rotation slot 431 is provided on the second pivot portion 42 . The rotation shaft 432 is provided on the first pivot portion 41 .

[0054] In a preferred embodiment, the connection back surface 221 of the connection cover 22 is in contact with the support back surface 31. In other words, the connection back surface 221 can rotate around the intersection line. This design is simpler and more beautiful.

[0055] In this embodiment, if Figure 1 、 Figure 4 and Figure 5 As shown, the first pivot portion 41 includes a first pivot fixing portion 411 disposed on the connecting body 21, and a first pivot extension unit 412 integrally connected to the first pivot fixing portion 411 and facing away from the display screen 1. The second pivot portion 42 includes a second pivot fixing portion 421 disposed on the supporting portion 3, and a second pivot extension unit 422 integrally connected to the second pivot fixing portion 421 and extending toward the display screen 1. The rotation mechanism 43 is disposed between the first pivot extension unit 412 and the second pivot extension unit 422. Preferably, the display screen 1 device includes two first pivot portions 41 and second pivot portions 42 symmetrically arranged along a centerline. The rotation mechanism 43 may include two arc-shaped rotation slots 431 symmetrically arranged along the centerline, and a rotation shaft 432 extending through the two rotation slots 431.

[0056] In particular, such as Figure 6 As shown, when the supporting front surface 32 of the supporting portion 3 is attached to the display screen 1 , the supporting back surface 31 of the supporting portion 3 is parallel to the connecting back surface 221 .

[0057] Further, if Figures 7 to 14As shown, the rotating shaft 432 includes a bolt 434 that passes through the second pivot extension unit 422 and the first pivot extension unit 412 in sequence, and a cam 435, a spring washer 436 and a nut 437 that are arranged on the bolt 434 from the inside to the outside, wherein the cam 435 is adjacent to the first pivot extension unit 412, and the cam 435 has a protrusion 4351 on the side facing the first pivot extension unit 412. Accordingly, a corresponding groove 4352 is provided on the first pivot extension unit 412 for limiting the cam 435. Specifically, the force is achieved by adjusting the pre-tightening of the nut 437, so as to achieve a suitable feel when adjusting the angle of the support portion. During rotation, the first pivot extension unit 412 rotates relative to the cam 435, and the protrusion 4351 of the cam 435 moves out of the groove 4352 of the first pivot extension unit 412 under the action of rotation. At this time, the protrusion 4351 of the cam 435 is against the plane of the first pivot extension unit 412. At the same time, the spring washer 436 located between the cam 435 and the nut 437 is squeezed, and the elastic force of the spring washer 436 reacts to the first pivot extension unit 412. By increasing the pressure, the friction force 422 between the first pivot extension unit 412 and the second pivot extension unit is increased, so that the support portion 3 can play a supporting and fixing purpose at any rotation angle. When the support front 32 is completely in contact with the back of the display screen 1, the protrusion 4351 of the cam 435 is inserted into the groove 4352 of the first pivot extension unit 412, and the cam 435 and the nut 437 no longer squeeze the spring washer 436, thereby releasing the force and making the support front 32 completely in contact with the back of the display screen 1.

[0058] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
