Referring to FIG. 2 and FIG. 5 and simultaneously with reference to FIG. 3, the fixing base 111 of the first hinge 11 is fixed (eg, screwed) to the base 10 by its fixing portion 1111. The first pivot 1 is substantially located in the space surrounded by the first accommodating groove 2311 and passes through the first fixing hole 2111 of the first connecting rod 21, the first pivoting portion 2321 of the body rod 23, the pivot hole 2322, and the torsion spring 113. The torque portion 1131 and the fixing hole 1113 of the fixing base 111, and the first pivot shaft 112 passes through the spacers 114 in a proper position (ie, between the above components) when passing through the above-mentioned components. Finally, the end of the first pivot 112 is locked by the nut 115.

It should be noted that, at this time, the first end portion 1132 of the torsion spring 113 of the first hinge 11 is disposed through the positioning hole 1114 of the positioning portion 1112 of the fixing base 111, and the second end portion 1133 is embedded in the rod body. A slot 2314 of 231. Thereby, the first end 1132 of the torsion spring 113 is passed through the fixing base 111 It is fixed on the base 10. The tab 212 of the first connecting rod 21 is received in the space surrounded by the recess 2317 of the body rod 23 and abuts against one of the opposite sides of the recess 2317.

Thereby, the first pivoting portion 2321 of the body rod 23 is pivotally disposed on the first pivot shaft 112 along the first axis C1, and the first connecting rod 21 is fixed to the first pivot shaft 112 along the first axis C1.

Further, a pin (not shown) is inserted through the pivot hole 2411 of the third pivoting portion 241 of the push-pull rod 24 and the pivot hole 2112 of the first connecting rod 21 to make the third pivoting portion 241 of the push-pull rod 24 The first connecting rod 21 is pivoted along the third axis C3. Further, the third axis C3 is parallel to the first axis C1.

The second pivot shaft 121 of the second hinge 12 passes through the second pivoting portion 2316 of the rod body 231 and the second fixing hole 221 of the second connecting rod 22 to make the second pivot of the body rod 23 The connecting portion 2315 is pivotally disposed on the second pivot shaft 121 along the second axis C2, and the second connecting rod 22 is fixed to the second pivot shaft 121 along the second axis C2. At this time, the portion of the second pivot shaft 121 passing through the pivot hole 2316 of the second pivot portion 2315 is substantially accommodated in the space surrounded by the second accommodating groove 2312. The second axis C2 is parallel to the first axis C1.

Furthermore, the second pivoting portion of the push-pull rod 24 is inserted through the pivot hole 2421 of the fourth pivoting portion 242 of the push-pull rod 24 and the pivot hole 222 of the second connecting rod 22 by another latch (not shown). The 242 is pivotally disposed on the second connecting rod 22 along the fourth axis C4. Further, the fourth axis C4 is parallel to the second axis C2.

It should be noted that, at this time, the push-pull rod 24 is substantially received in the accommodating space 2313 of the body rod 23 and the space surrounded by the first and second accommodating slots 2311, 2312. The body 244 and the hook 243 of the push-pull rod 24 are received in the accommodating space 2313 of the body rod 23, and the hook 243 of the push-pull rod 24 and the hook 2331 of the body rod 23 are located at positions facing each other. Place The first hook portion 32 of the tension spring 3 is hooked on the hook 2331 of the body rod 23, and the second hook portion 33 of the tension spring 3 is hooked on the hook 243 of the push-pull rod 24.

Thereby, the torsion spring 113 can be used to provide a torsion force and the torsion force can be used to resist the gravity of the screen 300 via the rod body 231 and the base 10, and the tension spring 3 can also be used to provide a pulling force and via the push rod 24 The body rod 23 allows the pulling force to be used to resist the weight of the screen 300.

That is to say, in this embodiment, the torque of the torsion spring 113 of the two supporting modules 20, 20' and the pulling force of the tension spring 3 are used to balance the gravity of the screen 300, so that the two supporting modules 20, 20' can be simultaneously A stop between a position and a second position.

The above describes the components of the support module 20 and their assembly and connection relationship when the support module 20 is in the first position. The following is an operation relationship in which the support module 20 is adjusted to the second position at the first position.

When the user applies the force to the rod body 231 of the support module 20, the rod body 231 is pivoted from the first position to the second position with the first axis C1 as the axis (ie, the position of FIG. 5 is changed toward the position of FIG. 7). The push-pull rod 24 will pivot with the third axis C3 as the axis. At this time, since the distance between the first axis C1 and the third axis C3 is greater than the distance between the second axis C2 and the fourth axis C4, that is, the first distance is greater than the second distance. Therefore, when the push-pull rod 24 pivots with the third axis C3 as the axis, the second connecting rod 22 is driven, and the second connecting rod 22 is pivotally linked with the second pivot 121 by using the second shaft C2 as an axis. Body rotation. When the second connecting rod 22 rotates by itself, the fourth pivoting portion 242 of the push-pull rod 24 is displaced in a direction close to the third pivoting portion 241. Moreover, while the second pivot shaft 121 rotates automatically, the angle between the screen 300 mounted on the second hinge 12 and the lead hammer surface is gradually increased (as shown in FIG. 8).

Further, the connection relationship between the first connecting rod 21, the second connecting rod 22, the body rod 23, and the push-pull rod 24 of the connecting unit 2 constitutes a non-parallel four-link configuration.

When the support module 20 is adjusted to the second position, the distance between the body rod 23 and the hooks 2331 and 243 of the push-pull rod 24 is increased due to the displacement of the fourth pivot portion 242, thereby making the tension spring 3 The elastic portion 31 is stretched to store a pulling force. At the same time, the second end portion 1133 of the torsion spring 113 is pressed by the fitting groove 2314 of the rod body 231 to twist the torsion portion 1131 to store a torque (see FIGS. 2 and 6).

Similarly, as shown in FIG. 8, the torque of the torsion spring 113 of the two supporting modules 20, 20' and the pulling force of the tension spring 3 balance the gravity of the screen 300, so that the two supporting modules 20, 20' can be maintained at the same time. Second position.

Moreover, when the support module 20 is adjusted to the second position, the tab 212 of the first connecting rod 21 is received in the space surrounded by the recess 2317 of the body rod 23, and abuts against the opposite sides of the recess 2317. The other side (not shown).

In addition, in addition to the second pivot 121 being coupled through the connecting unit 2, thereby adjusting the tilt angle of the screen 300, the screen 300 can also be directly rotated by the cooperation with the second hinge 12 to adjust the tilt angle (as shown in FIG. 9 screen position changes).

In the embodiment, the first distance is greater than the second distance, but the actual application is not limited thereto. For example, as long as the first distance is different from the second distance and then through the corresponding component design, the effect of the tilting of the screen 300 can be achieved while the support module 20 adjusts the angle.

In addition, the support module 20 of the present embodiment may not be used. It is used with the base 10. For example, the first hinge 11 of the support module 20 can be fixed (eg, screwed) on a working surface (such as a desktop).

In summary, the support device of the present embodiment simultaneously uses a tension spring and a torsion spring to balance the installed screen gravity, so that the support module can be stopped between the first position and the second position. Moreover, the support module replaces the conventional push rod and the pull rod through the design of the push-pull rod, so that the support module can achieve more compact components, facilitate assembly, and reduce the size.

Furthermore, the support module is configured such that when the distance between the first axis and the third axis is greater than the distance between the second axis and the fourth axis, the body rod pivots from the first position to the second position with the first axis as the axis. The angle between the screen and the plummet surface can be gradually increased by the connecting unit.

Moreover, through the structural design of the body rod, the push-pull rod can be accommodated in the space surrounded by the body rod, thereby achieving the effect of saving space and reducing the volume of the support module.

In addition, the supporting device of the present embodiment preferably includes two supporting modules for balancing the gravity of the screen through the torsion springs and the tension springs of the two supporting modules.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the patent of the present invention.
