Next, referring to Figures 4 to 6, the relationship of the components under the operation of the present invention will be described. FIG. 4 is a schematic view showing the state in which the carrier of the screen supporting device of the present invention is in the first end state, and FIG. 5 is a view showing the creation of the present invention. FIG. 6 is a schematic view showing the state in which the carrier of the screen supporting device is in the second end state, and FIG. 6 is a view showing the state in which the carrier of the screen supporting device of the present invention is located between the first end and the second end. It should be noted that in Fig. 4, a screen 8 is locked to the carrier 4, and a user P adjacent to the second end 112 side of the rack 11 is provided for convenience of the following description.

When the carrier 4 is located at the second end 312 of the first link 31, the angle θ _{1 of} the first link 31 with respect to the bottom plate 10 is the largest (about 90 degrees in this embodiment), at this time The shaft 2 is located at the first end portion 111 of the rack 11; when the first link 31 is operated by an external force F (ie, arrow F in FIG. 4) to pivot relative to the base 1, the shaft The rod 2 is advanced from the first end portion 111 of the rack 11 to the second end portion 112, and the shaft 2 is wound around the linking member 5 connected thereto to drive the carrier member 4 from the first connecting rod The second end 312 of the 31 is approached to the first end 311, and finally the angle θ _{2 of} the first link 31 relative to the bottom plate 10 can be minimized (about 0 degrees in this embodiment).

Further, the user P can apply an external force F to the screen 8. As shown in FIG. 4, the external force F is preferably (but not limited to) applied to the screen 8 corresponding to the first link 31. The portion of the second end 312 is such that the first link 31 is pivoted relative to the pivotal portion 30 of the second link 32, that is, the second end 312 of the first link 31 is along the arrow. Direction A The base 1 is close. At this time, since the first end 311 of the first link 31 is pivotally connected to the shaft 2, and the plurality of teeth 21 on the surface of the shaft 2 are engaged with the rack 11 on the bottom plate 10, The second end 312 of the first link 31 approaches the base 1 in the direction of the arrow A, and the shaft 2 pivotally connected to the first end 311 of the first link 31 is on the rack 11 The direction of the arrow B rolls from the first end portion 111 to the second end portion 112. At this time, the shaft 2 retracts the linkage 5 to move the screen 8 from the second end 312 to the first end 311 in the direction of the arrow C. Finally, the first link 31 can be parallel to the bottom plate 10 as shown in FIG.

In other words, such a design allows the screen 8 to be closer to the user P when it is in a near horizontal state to facilitate, for example, a touch operation; and the screen 8 is closer to the vertical state than the user P. Far away, avoid viewing the screen 8 when it is too close to produce visual pressure.

When the user P applies the external force F to the screen 8 and the shaft 2 is displaced on the rack 11, the second spring is fixed on the bottom plate 2 at one end of the shaft 2 7 (may be a constant force spring) can provide a certain force to the shaft 2, so that the shaft 2 can be relatively stopped with the first end of the rack 11 by the user P controlling the external force F. The portion 111 is between the portion 111 and the second end portion 112. Similarly, the first spring 6 disposed on the second end 312 of the first link 31 and having one end fixed to the carrier 4 can always provide a certain force to the carrier 4, so that the carrier 4 is When the shaft 2 is retracted by the linkage 5 and displaced, it can be relatively stopped between the first end 311 and the second end 312 of the first link 31.

In addition, FIG. 6 shows a state in which the screen 8 is stopped at any angle after the external force is applied, wherein the angle θ _{3 of} the first link 31 with respect to the bottom plate 10 is inclined with the first link 31. The angle changes, but the angle θ ₃ will be between the angle θ ₁ and the angle θ ₂ , the position of the carrier 4 will be between the first end 311 and the second end 312, and the shaft 2 also follows the first link The 31 changes and moves in the chute 120, not located closest to or farthest from the user P.

On the other hand, when the screen 8 needs to be restored, the user P can hold the screen 8 upward to drive the first link 31, and the first link 31 is displaced in the direction opposite to the arrow A of FIG. The first link 31 pivots relative to the second link 32 with the pivot joint 30 as an axis, that is, the second end 312 of the first link 31 is away from the base 1 in the opposite direction of the arrow A, due to the first connection The first end 311 of the rod 31 is a pivoting shaft 2, and the plurality of teeth 21 of the shaft 2 are engaged with the rack 11 of the bottom plate 10, and thus, as the second end 312 of the first link 31 is reversed When the direction of the arrow A is away from the base 1, the shaft 2 pivotally connected to the first end 311 of the first link 31 will be on the rack 11, and the second end 112 will be in the opposite direction of the arrow B. Moving to the first end portion 111, based on the linkage member 5 is connecting the carrier member 4 and the shaft 2, when the shaft 2 moves on the rack 11, the shaft 2 will be wound around the linkage member 5, causing the screen 8 to follow the arrow The reverse direction of the number C is moved from the first end 311 to the second end 312, so that the first link 31 is perpendicular to the bottom plate 10. The foregoing operation can be sequentially performed by the fifth, sixth and fourth figures. Render state to represent.

Further, the ratio of the small diameter section 2a to the large diameter section 2b described above may be, for example, between 1.2 and 2.5, and the purpose thereof mainly causes a difference in the moving effect of the connecting small diameter section 2a and the large diameter section 2b. For example, the linkage 5 is connected to the large The diameter section 2b, and the small diameter section 2a can mesh with the rack 11 through the plurality of teeth 21, and if the diameter ratio of the two is 1.8, when the movement of the screen is 1.8 cm, the shaft 2 only moves horizontally. Only 1 cm. Through the proportional relationship between the small diameter section 2a and the large diameter section 2b, the displacement of the two can be prevented from being equidistant. If the displacement of the two is an equidistant effect, the sliding slot 120 of the base 1 needs to have the same distance from the screen displacement. Space, this will cause the overall volume of the base 1 to be too long.

Compared with the prior art, the screen support device of the present invention provides a more practical support device design, which is meshed with both the shaft and the rack, so that the carrier can move on the first link of the link unit. In particular, in a state where the first link and the base are perpendicular to the first link and the base, the screen on the carrier can be moved from one end of the first link to the other end, so that the screen is closer to the user and the user is beneficial. Watching, in addition, in this creation, when the support device is swayed, the screen will move above the base and not protrude from the base, which will make the overall volume small and easy to store. Therefore, the screen support device of the present invention is used. Or it can be more flexible when stored.

The above embodiments are merely illustrative of the principles of the present invention and its effects, and are not intended to limit the present invention. Anyone familiar with the art may modify the above embodiments without departing from the spirit and scope of the creation. Therefore, the scope of protection of this creation should be as listed in the scope of patent application described later.
