Detailed Description

Fig. 1 is a schematic view of a stand structure and a display device according to an embodiment of the present invention. Fig. 2 is an exploded view of a portion of the components of the stand structure of fig. 1. Cartesian coordinates X-Y-Z are provided herein to facilitate component description. Referring to fig. 1 and fig. 2, in the present embodiment, the stand structure 100 is used for supporting the display device 200. The stand structure 100 includes an upright 110, a coupling module 120, a base 130, and a rotating module 140. The upright 110 has a first end E1 and a second end E2 opposite to each other, and the first end E1 is provided with a coupling module 120 to facilitate assembly to the display device 200. The present embodiment shows the combination module 120 being assembled with the display device 200 in a partially embedded manner, but the present invention is not limited thereto. The rotating module 140 is disposed in the base 130, the base 130 includes a carrying tray 131, a first cover 132 and a second cover 133, and after the rotating module 140 is assembled to the carrying tray 131, the first cover 132 and the second cover 133 are assembled to the carrying tray 131 opposite to each other (along the X axis but opposite to each other) to shield the rotating module 140. As can be seen from a comparison of fig. 1 and 2, the second end E2 of the upright 110 is assembled to the rotating module 140 and substantially extends into the base 130.

Here, the rotation module 140 has a rotation axis and is the same as the extension axis of the vertical rod 110, and the embodiment will be exemplified by an axis Z1, and the axis Z1 is substantially parallel to the Z axis of the rectangular coordinates X-Y-Z. Through the above assembly, the upright 110 and the display device 200 assembled thereon can be rotated relative to the base 130 by the rotation module 140 about the axis Z1, and fig. 1 illustrates a plurality of different connecting lines, which represent that the display device 200 has different rotation states C1, C2 and C3, but not limited thereto.

Fig. 3 and 4 are exploded views of a part of the components of the stand structure from different perspectives. Referring to fig. 2 to 4, in the present embodiment, the rotating module 140 has a fixing element 141 and a rotating element 142 coupled to each other and disposed coaxially with the vertical rod 110 (i.e., the axis Z1). The fixing member 141 is assembled to the carrying plate 131 of the base 130 by the locking attachment 145, the rotating member 142 is assembled to the second end E2 of the upright 110, and the second end E2 of the upright 110 substantially extends into the base 130 when the first cover 132 and the second cover 133 are assembled to the carrying plate 131.

Further, the rotating assembly 142 includes a first rotating member T1 and a second rotating member T2, the first rotating member T1 is assembled to the second end E2 of the upright 110 by a locking attachment 144, and the locking attachment 143 is used to adjustably assemble the first rotating member T1 and the second rotating member T2 together and clamp a portion of the fixing member 141 between the first rotating member T1 and the second rotating member T2. When a user applies force and rotates the display device 200, the upright 110 can drive the first rotating member T1 and the second rotating member T2 to rotate relative to the fixing member 141 and the base 130. The "adjustable assembly" is that the locking piece 143 is partially passed through the second rotating piece T2 and locked to the first rotating piece T1, and the degree of the clamping of the fixing piece 141 to the first rotating piece T1 and the second rotating piece T2 depends on the depth of the locking piece 143 locked to the first rotating piece T1.

Figure 5 is a partial cross-sectional view of the stand structure. Referring to fig. 3 to 5, in detail, the first rotating member T1 includes a first part a1 and a second part a2, the first part a1 is assembled to the second end E2 of the vertical rod 110 by the locking accessory 144, the second part a2 is disposed on the first annular portion N1 of the first part a1, and the second part a2 has at least one first annular rib (three first annular ribs R1 are illustrated as an example, but not limited thereto), and the first annular rib R1 abuts against the fixing member 141 with respect to the first annular portion N1.

In contrast, the second rotating element T2 includes a third part A3 and a fourth part a4, the third part A3 is adjustably assembled to the first rotating element T1 (and particularly the first part a1) by the locking accessory 143, the fourth part a4 is disposed on the second annular portion N2 of the third part A3, and the fourth part a4 has at least one second annular rib (here, three second annular ribs R2 are shown as an example, but not limited thereto), back to the second annular portion N2, and the second annular rib R2 abuts against the fixing element 141.

As is clear from fig. 5, the first rotating member T1 and the second rotating member T2 are abutted against the fixing member 141 by the first annular protruding rib R1 and the second annular protruding rib R2, and the second member a2 and the fourth member a4 are made of Polyoxymethylene (POM), and the fixing member 141 is made of metal, so that the first rotating member T1 and the second rotating member T2 can be in line contact with the fixing member 141, and the structural contact area is reduced, and the friction force can be effectively reduced by matching the Polyoxymethylene material, thereby facilitating the smooth rotation of the first rotating member T1 and the second rotating member T2 with respect to the fixing member 141 by the axis Z1.

It should be noted that, although the first rotating element T1 and the second rotating element T2 of the present embodiment are respectively composed of a plurality of components, the component types thereof are not limited thereby. In another embodiment, not shown, the first rotating member or the second rotating member may be a single member, and the annular rib is formed thereon by plating, which can also achieve the same effect as the above embodiment.

Referring to fig. 3 and 4, in the present embodiment, for the locking accessory 143, such as a flat-head screw, the threaded portion passes through the third component A3 and is locked into the locking boss 142b of the first component a1, and the head portion thereof is still retained in the locking relationship with the limiting hole 142d of the third component A3, so that the relative distance between the first rotating member T1 and the second rotating member T2 along the axis Z1 can be adjusted according to the depth of the locking accessory 143 locked into the locking boss 142b, which is also equivalent to the interference degree of the two members with the fixing member 141. In addition, the locking attachment 144 of the present embodiment is locked into the locking attachment hole of the upright 110 at the second end E2 through the opening 142c of the first member A1. On the other hand, the fixing member 141 of the present embodiment has the flat-topped ridge structure 141b, which is sandwiched between the first rotating member T1 and the second rotating member T2, the first rotating member T1 abuts against the flat-topped portion of the flat-topped ridge structure 141b, and the second rotating member T2 abuts against the concave portion of the flat-topped ridge structure 141 b.

In the embodiment, the rotating element 142 has a guiding protrusion 142a, the opening 141a of the fixing element 141 has a guiding notch S1, the guiding protrusion 142a is movably coupled to the guiding notch S1, and the inner diameter of the guiding notch S1 relative to the axis Z1 is larger than the inner diameter of the remaining portion (the engaging portion S2) of the opening 141a relative to the axis Z1. Correspondingly, the rotating member 142 further has a coupling protrusion 142e fitted into the opening 141a, and the radius of rotation of the guide protrusion 142a with respect to the axis Z1 is larger than the outer diameter of the coupling protrusion 142e with respect to the axis Z1. The moving path L1 of the guide protrusion 142a in the guide notch S1 determines the rotation angle of the display device 200 and the upright 110 with respect to the base 130 about the axis Z1. Specifically, the first member a1 of the first rotary piece T1 has the above-mentioned guide projection 142a and the engagement projection 142e, and the guide projection 142a is separated from the axis Z1 with respect to the axis Z1 as a reference, compared with the engagement projection 142 e. Correspondingly, the opening 141a of the fixing member 141 can be divided into a combination portion S2 and the aforementioned guiding notch S1, wherein the combination protrusion 142e is adapted to the combination portion S2, so that the first rotating member T1 can rotate relative to the fixing member 141, and the guiding protrusion 142a can only move back and forth in the range of the guiding notch S1 along the moving path L1, thereby providing range limitation for the rotation angles of the first rotating member T1, the rotating assembly 142, and the rotating module 140 relative to the base 130. In another embodiment, not shown, the guiding protrusion 142a may be disposed on the second rotating member T2 instead, and the guiding protrusion can move in the guiding notch S1.

In summary, in the above embodiments of the present invention, the stand structure is formed by assembling the vertical rod, the base and the rotation module, and the rotation module is disposed in the base and serves as a connecting member between the vertical rod and the base, so that when the display device is assembled to the vertical rod, the display device and the rotation module are located at two opposite ends of the vertical rod, that is, when the user wants to rotate the display device to change its viewing angle, the user applies a force to the display device to rotate the display device and the vertical rod relative to the base through the rotation module with the same rotation axis. The rotating module is far away from the joint of the upright rod and the display device to improve the rotating moment during rotation, so that a user can rotate the display device in a labor-saving mode.
