Description

screen rotation structure

This creation is about a screen rotation structure, especially a kind of effect that can achieve good operation convenience and prevent the screen from interfering with the desktop when rotating.

With the widespread use of flat-panel displays, the functions of the support frame used to support the display screen have become more and more complete and diversified, such as adjusting the elevation angle, rotating left and right, or adjusting the height up and down. In general, the rotating function of the support frame of the existing screen usually uses a hinge (Hinge) as a single-point axis to rotate the screen. When the screen is displayed, the screen will be reduced and inconvenient. For the convenience of viewing the screen, the screen must be rotated from a horizontal horizontal state to a vertical vertical state by the rotating function of the support frame. However, another problem extends, that is, in the process of rotating the horizontal screen into a vertical screen, the screen is easily obstructed by the desktop and cannot continue to rotate (rotate), so the user must first install the support frame. When the height is raised upwards, the height needs to be adjusted so that the screen will not touch the desktop during the process of turning the screen vertically, and then the screen can be rotated from horizontal to vertical, resulting in poor operating convenience. In addition, the rotation function of the existing support frame can only make the screen stand still at the two angles of the horizontal and vertical directions, but the rotation angle between the horizontal and vertical directions of the screen cannot be maintained, that is, when the screen is rotated from horizontal to vertical. When the user rotates the screen upwards, such as 45 or 65 degrees from the landscape, the user's hand does not continue to support the screen, and the screen will quickly fall back to the horizontal position due to the heavy weight of the screen due to the acceleration of gravity, resulting in damage to the screen or the support frame, and Problems such as poor safety in use.

Referring back to FIG. 3A, the first sliding group 13 is further provided with a linking portion 135 and an abutting portion 136, which are attached to the linking portion 135. The linking portion 135 is, for example, a rod body and is located at the pair of stop portions 126, that is, one end of the linking portion 135 is connected to the outer side 1311 of the sliding body 131 of the first sliding group 13, and the other end of the linking portion 135 is pivoted on the bearing body 12, so that the linking The part 135 slides and displaces back and forth in the first arc-shaped chute 123 along with the sliding body 131 of the first sliding group 13 , and the pair of stop parts 126 limits the back and forth sliding displacement range of the linkage part 135 , and also limits The sliding range of the sliding body 131 of the first sliding group 13 can effectively protect the sliding body 131 of the first sliding group 13 from being damaged by over-sliding. Please refer to FIGS. 4A and 4B , and also refer to FIG. 1 , the third sliding group 15 is further provided with a pair of sliding rails 155 and a moving plate 156 . The pair of sliding rails 155 are disposed on the rear side 121 of the carrying body 12 and are adjacent to each other. The two sides of the linear sliding groove 125 , that is, the pair of sliding rails 155 , for example, a linear sliding rail 155 is disposed parallel to the linear sliding groove 125 . The moving plate 156 is slidably connected to the pair of slide rails 155 , and has an opening 1561 penetrating both sides of the moving plate 156 . The opening 1561 is connected to one end of the sliding body 151 of the third sliding group 15 . In combination with the sleeves, the moving plate 156 slides upwards or downwards on the pair of sliding rails 155 along with the sliding body 151 of the third sliding group 15 in the linear sliding groove 125 . An elastic member 17 is disposed between the pair of sliding rails 155 of the third sliding group 15 and is disposed adjacent to the top side of the carrying body 12 and is located above the linear sliding groove 125 to be connected with the moving plate 156 , that is, The elastic member 17 is, for example, a rollable constant-force spring (or a constant-force tension spring), which has the functions of rewinding a constant force and a fixed force, so that one end of the elastic member 17 can be elastically slid with the moving plate 156 upward. The deformation rolls to retract, or the elastic deformation rolls to stretch as the moving plate 156 slides down. When the horizontally arranged (horizontal screen) screen 2 is rotated to any rotation angle (such as 0°~90°) and any height between the vertically arranged (portrait screen) screens 2, the elastic member 17 enables the The screen 2 is maintained in a stop (hovering) state. For example, after the screen 2 is rotated up to an angle of 45 degrees in a horizontal arrangement (eg, a 0-degree position), the elastic member 17 has a fixed force characteristic to allow the moving plate 156 The sliding bodies 131 , 141 , 151 of the first, second, and third sliding groups 13 , 14 , 15 are kept at the current moving positions, which are kept fixed at the current moving positions. In this way, the overall safety effect is effectively improved, and the conventional problem that the screen 2 falls and hurts the user due to the heavy weight of the screen 2 after the screen 2 is rotated halfway and suddenly leaves the screen 2 can be improved. Referring to Figures 1 and 5, in order to place the screen rotating structure 1 on a carrier 3 (such as a table 3), a base 19 can be added at the bottom, and a box 18 can be added at the periphery for protection and dustproof use, that is, The screen rotating structure 1 further includes a box body 18 and a base 19 disposed at the bottom of the box body 18 . The box body 18 is provided with an outer cover 182 which is closed on a frame portion 183 . The frame portion 183 has an accommodating space 1831 in which the carrying body 12 is placed. And a plurality of slots 181 are provided on the bottom side of the frame portion 183 of the accommodating space 1831. The slots 181 correspond to the first and second arc-shaped chute The grooves 181 are respectively penetrated by the first, second and third joint parts 112 , 113 and 114 , so that the first, second and third joint parts 112 , 113 and 114 are combined with the box body 18 . Therefore, the carrying body 12 is enclosed in the box body 18 to effectively protect the carrying body 12 and achieve a dustproof effect. In addition, the free space in the accommodating space 1831 of the box body 18 (eg the accommodating space 1831 is not provided with the slot 181) can be used for accommodating other components (such as PC motherboards, fans, hard disk electronic components). The following is an implementation description: Referring to Figures 1, 4A, 4B and 5, when the screen 2 is rotated, after the user exerts upward force on the horizontally arranged screen 2, the joint 11 on the screen 2 is subjected to upward force to rotate upward (eg While rotating counterclockwise; as shown in Figure 4A), the sliding body 131 of the first sliding group 13 slides from left to right along the first arc-shaped chute 123, and the second and third sliding groups 14, 15 The sliding bodies 141 and 151 respectively follow the second arc-shaped sliding grooves 124 And the linear chute 125 slides from bottom to top. When the rotation angle (eg, 75 degrees) of the coupling element 11 is close to the vertical arrangement angle (eg, 90 degrees), the sliding body 131 of the first sliding group 13 is close to the middle position of the first arc-shaped sliding groove 123, and the The sliding bodies 151 of the second and third sliding groups 15 are respectively close to the second arc-shaped chute 124 and the upper end of the linear chute 125 (as shown in FIG. 4B ). The sliding body 131 of a sliding group 13 stays at the end 1231 of the first arc-shaped sliding groove 123 , and the sliding bodies 141 and 151 of the second and third sliding groups 14 and 15 respectively stay at the second arc-shaped sliding groove 124 and the middle position of the linear chute 125 (as shown in Figure 4B). Therefore, in the design of the screen rotation structure 1 of the present creation, the sliding bodies 131 , 141 and 151 of the first, second and third sliding groups 13 , 14 and 15 are three independent and all have different axes, so that the combination element 11 During the rotation process, the sliding bodies 131, 141 and 151 of the first, second and third sliding groups 13, 14 and 15 will continuously change their positions, so that the screen 2 on the joint 11 is always at the most suitable height, and The screen 2 can be directly rotated and adjusted to any viewing angle, and has the characteristics of vertical, horizontal and oblique adjustment, so that the screen 2 will not be hindered by a table top 31 of the table 3 when rotating, and also effectively achieves good operational convenience. Therefore, this creation effectively improves the conventional problem that when the screen 2 is rotated, the height of the support frame supporting the screen 2 must be raised up to a height where the screen 2 rotation will not hit the desktop before the screen 2 rotation adjustment can be performed.
