Abstract

Disclosed is a supporting module for a display device, which includes a fixing seat, a pivot lever, a slider and a spring. The pivot lever and the slider constitute a screw transmission mechanism. The pivot motion of the pivot lever can cause screw motion between the pivot lever and the slider and thus induces the linear movement of the slider with respect to the pivot lever. Accordingly, the displacement of the slider causes different degrees of deformation in the spring, resulting in different spring resilience forces on the slider. By the screw transmission mechanism, the different spring resilience forces can be further converted into different resistance torques to balance with the downward torque caused by the weight of the display device. As a result, the display device can stopped at any desired height.

First claim

What is claimed is:

1. A supporting module for a display device, the supporting module comprising:
a fixing seat, having a guide structure, wherein the guide structure defines a linear path;
a pivot lever, having a shaft and an arm, wherein (i) the shaft is rotatably connected to the fixing seat and has a central axis parallel to the linear path, (ii) the arm is connected to the shaft and used for mounting the display device, and (iii) the arm is configured to be pivotable about the central axis of the shaft so as to bring the shaft into rotary motion;
a slider, being sleeved on the shaft, wherein a screw transmission mechanism is constituted by the slider and the shaft, and the slider is brought into linear movement along the linear path with respect to the shaft when the arm is forced to induce the rotary motion of the shaft; and
a spring, having a mobile end and an immobile end, wherein the mobile end moves with the slider and the immobile end keeps stationary when the slider moves along the linear path, so that the linear movement of the slider causes different degrees of deformation in the spring, resulting in different spring resilience forces on the slider, and the different spring resilience forces are further converted into different resistance torques through the screw transmission mechanism so as to stop the display device at any desired height.

2. The supporting module of claim 1 , wherein the shaft is externally threaded and the slider is internally threaded, and the shaft and the slider are threadedly connected to each other, so as to constitute the screw transmission mechanism.

3. The supporting module of claim 1 , wherein the spring is a compression spring.

4. The supporting module of claim 3 , wherein the slider has a bearing face in contact with the mobile end of the spring, and the bearing face has a larger area than a cross-sectional area of the spring.

5. The supporting module of claim 4 , wherein (i) the slider includes a screwing part and a bearing plate, (ii) the shaft is threadedly connected to the screwing part and extends through the bearing plate, and (iii) the mobile end of the spring abuts against the bearing plate.

6. The supporting module of claim 1 , further comprising a sleeve sleeved on the shaft and having an exterior surface abutting against an internal surface of the spring.

7. The supporting module of claim 1 , wherein the deformation of the spring is reduced when the arm is pivoted to decrease effective moment arm.

8. The supporting module of claim 1 , wherein (i) the fixing seat further has a base plate, a first lateral plate and a second lateral plate, (ii) the first lateral plate and the second lateral plate are erected on the base plate, and (iii) the shaft extends through the first lateral plate, the slider, the spring and the second lateral plate in sequence, and is rotatably connected to the first lateral plate and the second lateral plate.

9. The supporting module of claim 8 , wherein the mobile end and the immobile end of the spring abut against the slider and the second lateral plate of the fixing seat, respectively.

10. The supporting module of claim 9 , wherein the second lateral plate has an abutting face in contact with the immobile end of the spring, and the abutting face has a larger area than the cross-sectional area of the spring.

11. The supporting module of claim 8 , wherein the guide structure of the fixing seat includes a first guide rod and a second guide rod, and the first guide rod and the second guide rod extend through the slider along a direction parallel to the central axis of the shaft and are connected to the second lateral plate to permit the linear movement of the slider along the first guide rod and the second guide rod.

12. The supporting module of claim 11 , wherein (i) the fixing seat further has a third lateral plate between the second lateral plate and the spring, (ii) the shaft, the first guide rod and the second guide rod extend through the third lateral plate, and (iii) the mobile end and the immobile end of the spring abut against the slider and the third lateral plate, respectively.

13. The supporting module of claim 12 , wherein the third lateral plate has an abutting face in contact with the immobile end of the spring, and the abutting face has a larger area than the cross-sectional area of the spring.

14. The supporting module of claim 12 , wherein at least one of the first guide rod and the second guide rod is rotatably connected to the first lateral plate and the second lateral plate and threadedly connected to the third lateral plate, and preload of the spring is adjustable by rotating at least one of the first guide rod and the second guide rod.

15. The supporting module of claim 11 , wherein (i) each of the first guide rod and the second guide rod has a shaft portion and a head portion, (ii) the shaft portions extend through the slider, and (iii) each of the head portion has a diameter larger than that of the shaft portions to stop the slider departing from the first guide rod and the second guide rod in a direction toward the first lateral plate.

16. The supporting module of claim 11 , wherein the first guide rod and the second guide rod extend to and are connected to the first lateral plate of the fixing seat.

17. The supporting module of claim 15 , wherein (i) each of the first guide rod and the second guide rod further has a nut, (ii) the shaft portions are affixed to the second lateral plate of the fixing seat through the nuts, and (iii) preload of the spring is adjustable by changing relative location of the nuts on the shaft portions.
