Description

Screen rotation structure

The present invention relates to a screen rotation structure, in particular to a screen rotation structure that achieves good operational convenience and prevents the screen from interfering with the desktop when rotating.

With the widespread use of flat-panel displays, the functions of support brackets used to support display screens have become more complete and diverse, such as elevation adjustment, left and right rotation, or height adjustment. Generally, the support rotation function of the existing screen usually uses a hinge as a single-point axis to rotate the screen. For example, the general screen is mostly horizontal when used, and the display screen is also horizontal. When viewing vertical documents, pictures or When the screen is displayed, the screen will shrink and appear inconvenient. In order to facilitate the viewing of the screen, the screen must be rotated from a horizontal horizontal state to a straight vertical state through the rotation function of the support bracket. But another problem arises, that is, when rotating a horizontal screen into a vertical screen, the screen is easily blocked by the desktop and cannot continue to rotate (rotate), so the user must first move the support bracket. Adjust the height upwards. This height needs to be adjusted so that the screen does not touch the desktop when it is turned into a vertical position, and then the screen can be rotated from horizontal to vertical, which makes the operation convenience in use poor.

In addition, the rotation function of the existing support bracket can only make the screen stop at two angles: horizontal and vertical. However, the rotation angle between the horizontal and vertical rotation of the screen cannot be maintained, that is, when When the user rotates the screen upwards from the horizontal direction, such as 45 or 65 degrees, and the user's hands do not continue to support the screen, the screen will quickly fall back to the horizontal position due to gravity acceleration due to the excessive weight, resulting in damage to the screen or the support frame, and in Problems such as poor safety in use.

One object of the present invention is to provide a screen rotation structure that can achieve good operational convenience and prevent the screen from interfering with the desktop when rotating.

In order to achieve the above object, the present invention provides a screen rotation structure for connecting a screen. The screen rotation structure includes: a connecting member having a connecting side and a connecting side respectively located on both sides of the connecting member. The connecting side is connected to On a rear side of the screen, the coupling side has a first coupling part, a second coupling part and a third coupling part; a carrying body has a chute part corresponding to the coupling side of the coupling piece, the chute The part includes a first arc-shaped chute extending from the right side of a virtual vertical center line of the carrying body to the left side of the virtual vertical center line with an end, and a second arc-shaped chute is provided on the left side of the end of the first arc-shaped chute. An arc-shaped chute is provided with a linear chute on the right side of the end of the first arc-shaped chute. The second arc-shaped chute goes from the lower side of a virtual horizontal center line of the carrying body to the upper side of the virtual horizontal center line. Extend, the linear chute extends upward from the upper side of the first arc-shaped chute; and the plurality of sliding groups includes a first sliding group, a second sliding group and a third sliding group respectively located on the first arc-shaped sliding chute. In the groove, the second arc-shaped chute and the linear chute, one end of the first, second and third sliding groups are respectively connected with the first, second and third connecting parts of the connecting piece.

By the present invention, the first and second sliding groups slide along the arc-shaped extending directions of the first and second arc-shaped chute respectively and the third sliding group slides in the linear chute, so that each connecting portion follows the corresponding The sliding group slides to drive the screen to rotate, so that the screen will not interfere with the desktop when rotating, and the operation convenience is good.

Referring to Figures 1, 3A, and 3B together below, the structure and connection relationship of the first, second, and third sliding groups 13, 14, and 15 will be described in detail.

Each of the first, second and third sliding groups 13, 14 and 15 has a sliding body 131, 141 and 151 and a connecting piece 133, 143 and 153. In this embodiment, the structure of the sliding bodies 131 and 141 of the first and second sliding groups 13 and 14 is different from the structure of the sliding body 151 of the third sliding group 15 . 131 and 141 are composed of two sliding blocks, and the sliding body 151 of the third sliding group 15 is composed of one sliding block, but is not limited to this. During specific implementation, the structures of the sliding bodies 131 , 141 , and 151 of the first, second, and third sliding groups 13 , 14 , and 15 can also be designed to be the same, which will be explained below.

The sliding bodies 131, 141, and 151 of the first, second, and third sliding groups 13, 14, and 15 respectively have a sliding body outer side 1311, 1411, 1511, and a sliding body through hole 1312, 1412, 1512 that penetrates each sliding body 131. ,141,151. The outer sides 1311, 1411, and 1511 of the sliding bodies of the first, second, and third sliding groups 13, 14, and 15 are respectively slidably disposed in the corresponding first and second arcuate slide grooves 123, 124, and the linear slide groove 125. Specifically, the sliding body 131 of the first sliding group 13 slides back and forth along the arc direction of the first arc-shaped chute 123 (such as sliding from left to right or from right to left), and the second The sliding bodies 141 and 151 of the three sliding groups respectively slide back and forth along the arc direction of the second arc-shaped chute 124 and the linear direction of the linear chute 125 (such as sliding from bottom to top or sliding from top to bottom). ).

The connecting pieces 133 and 143 (such as screws) of the first and second sliding groups 13 and 14 respectively penetrate into the sliding body through holes 1312 and 1412 of the first and second sliding bodies 131 and 141 and are connected with the corresponding third sliding body. The first and second coupling parts 112 and 113 are locked and connected. The connecting piece 153 (such as a nut) of the third sliding group 15 is locked with one end of the third connecting portion 114 of the connecting piece 11 that passes through the third sliding body 151 . In this way, the coupling member 11 is coupled to the carrying body 12 . In this embodiment, the connectors 133, 143, and 153 of the first, second, and third sliding groups 13, 14, and 15 are screw-lock structures that match the first, second, and third joint portions 112, 113, and 114, respectively. It is not limited to this. In another embodiment, the connectors 133, 143, and 153 of the first, second, and third sliding groups 13, 14, and 15 respectively and the first, second, and third joint portions 112, 113, and 114 may be pin structures that match. or other matching combination structures.

Referring back to Figure 3A, the first sliding group 13 is further provided with a linking part 135 and a resisting part 136 provided on the linking part 135. The linking part 135 is, for example, a rod body and is located on the pair of stop parts. 126 , that is, one end of the linkage part 135 is connected to the outer side 1311 of the slide body 131 of the first sliding group 13 , and the other end of the linkage part 135 is pivoted on the load-bearing body 12 , so that the linkage part 135 The portion 135 slides back and forth as the sliding body 131 of the first sliding group 13 slides back and forth in the first arc-shaped slide groove 123, and the pair of stopper portions 126 limits the back-and-forth sliding displacement of the linking portion 135, thereby also limiting the back-and-forth sliding displacement. 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 over-sliding and impact damage.

Please refer to Figures 4A and 4B, and with reference to Figure 1, the third sliding group 15 is further provided with a pair of slide rails 155 and a moving plate 156. The pair of slide rails 155 is located on the rear side 121 of the carrying body 12 and adjacent to it. The two sides of the linear slide groove 125 , that is, the pair of slide rails 155 are, for example, a linear slide rail 155 arranged parallel to the linear slide groove 125 . The moving plate 156 is slidably connected across the pair of slide rails 155 and is provided with 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. Combined with each other, the The moving plate 156 slides and displaces upward or downward on the pair of slide rails 155 as the slide body 151 of the third sliding group 15 slides back and forth in the linear slide groove 125 .

An elastic member 17 is provided between the pair of slide rails 155 of the third sliding group 15 and is located adjacent to the top side of the carrying body 12 and located above the linear slide 125 and connected to the moving plate 156, that is, The elastic member 17 is, for example, a rollable fixed-force spring (or constant-force tension spring), which has the function of rewinding a fixed force and a fixed force, so that one end of the elastic member 17 can slide upward with the moving plate 156 to become elastic. The deformation rolls and retracts, or the elastic deformation rolls and stretches as the moving plate 156 slides downward. When the screen 2 in a horizontal arrangement (horizontal screen) is rotated to any rotation angle (such as 0 degrees ~ 90 degrees) and any height between the screens 2 in an upright arrangement (vertical screen), the elastic member 17 causes the The screen 2 remains in a stopped (hovering) state. For example, after the screen 2 is arranged horizontally (for example, at a 0-degree position) and rotates upward at an angle of, for example, 45 degrees, the elastic member 17 has a fixed force characteristic so that the moving plate 156 The sliding bodies 131, 141, and 151 of the first, second, and third sliding groups 13, 14, and 15 are also restricted to remain fixed at the current moving position. In this way, the overall safety effect is effectively improved, and it can also improve the conventional problem of suddenly letting go of the screen 2 when the screen 2 is halfway rotated, causing the screen 2 to fall on its own due to the excessive weight and injure the user.

Referring to Figures 1 and 5, in order to place the screen rotating structure 1 on a carrier 3 (such as a table 3) in the present invention, a base 19 can be added at the bottom, and a box 18 can be added around the periphery for protection and dustproof use, that is, The screen rotating structure 1 further includes a box 18 and a base 19 located at the bottom of the box 18 . The box body 18 is provided with an outer cover 182 which is covered with a frame part 183. The frame part 183 has an accommodating space 1831 for placing the carrying body 12. And a plurality of slots 181 are provided on the bottom side of the frame 183 of the accommodation space 1831. The slots 181 respectively correspond to the first and second arcuate chute 123, 124 and the linear chute 125. The grooves 181 are penetrated by the corresponding first, second, and third joint parts 112, 113, and 114 respectively, so that the box 18 is attached to the screen housing 21.

Therefore, the carrying body 12 is sealed in the box 18 to effectively protect the carrying body 12 and achieve dust-proof effect. In addition, the free space in the accommodating space 1831 of the box 18 (if the accommodating space 1831 is not provided with a slot 181) can be used to accommodate other components (such as PC motherboard, fan, hard disk electronic components).

An implementation description is as follows: Refer to Figures 1, 4A, 4B, and 5. When the screen 2 is rotated and the user exerts an upward force on the horizontally arranged screen 2, the coupling member 11 on the screen 2 is exerted upward. While rotating upward (such as counterclockwise rotation; 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 slide groove 123, and the second and third The sliding bodies 141 and 151 of the sliding groups 14 and 15 respectively slide along the second arcuate sliding groove 124 and the linear sliding groove 125 from bottom to top. When the rotation angle (such as 75 degrees) of the coupling member 11 is close to the upright installation angle (such as 90 degrees), the sliding body 131 of the first sliding group 13 is close to the middle position of the first arc-shaped slide groove 123, and the The sliding bodies 141 and 151 of the second and third sliding groups 14 and 15 are respectively close to the upper ends of the second arc-shaped chute 124 and the linear chute 125 (as shown in Figure 4B), and then rotate to the upright position of the screen 2 Finally, the sliding body 131 of the first sliding group 13 stays at the end 1231 of the first arc-shaped chute 123, and the sliding bodies 141 and 151 of the second and third sliding groups 14 and 15 respectively stay at the second The upper end of the arcuate chute 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 invention, the sliding bodies 131, 141, and 151 of the first, second, and third sliding groups 13, 14, and 15 are three independent and have different axes, so that the connecting member 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 positions, so that the screen 2 on the connecting piece 11 is always at the most appropriate height, and The screen 2 can be directly rotated and adjusted to any viewing angle and has vertical, horizontal and oblique adjustment characteristics, so that the screen 2 will not be hindered by a table top 31 of the table 3 when rotating, and it also effectively achieves good operational convenience. Therefore, the present invention effectively improves the conventional firefly When screen 2 is rotated, the height of the support bracket that supports screen 2 must be raised in advance to a height where screen 2 will not hit the table when rotating. Only then can screen 2 be rotated and adjusted.
