The type of the lifting member 230 is not limited by this.

Fig. 5 is an exploded view of the lifting device of Fig. 1. 3 to 5, in this embodiment, the linkage mechanism 240 further includes a first linkage 242, a second linkage 245, and a third linkage 247 that are linked in sequence. The first linkage 242 further includes a shaft 243 and a plate 244 connected to the shaft 243, and the shaft 242 is located beside the hinge assembly 250. The second link 245 and the third link 247 are, for example, two links.

Fig. 6 is a partial cross-sectional view of Fig. 1. Please refer to FIGS. 5 and 6 at the same time. The hinge assembly 250 further includes a driving member 256 extending from the second pivoting member 254. As shown in FIG. 6, the driving member 256 is arranged at a position deviated from a first axis L of the second pivoting member 254 and is fixed to the shaft 243 of the first linkage member 242 of the linkage mechanism 240. In this embodiment, the driving member 256 may be a bolt, but the type of the driving member 256 is not limited to this.

When the fixing bracket 210 and the supporting bracket 220 are on the same plane, they are fixed to A second axis R of the shaft 243 of the driving member 256 is coaxial with a first axis L of the second pivoting member 254 (FIG. 7 ). At this time, the driving member 256 is positioned directly above the first axis L.

Fig. 7 is a partial cross-sectional view of Fig. 2. Please refer to FIG. 7, when the supporting frame 220 rotates relative to the fixed bracket 210 instead of being located on the same plane, the second pivoting member 254 will rotate with the driving member 256. At this time, the driving member 256 will rotate to the first axis in FIG. 7 The shaft 243 fixed to the driving member 256 moves to the lower right with the driving member 256, so that the second axis R is located at the lower right relative to the first axis L. At this time, the second axis R and the first axis L are no longer coaxial but staggered.

When the support frame 220 rotates backward relative to the fixed support 210, the first linkage 242 will move slightly downward along the first surface 210a of the fixed support 210, thereby urging the second linkage 245 and the third linkage 247 sports.

Please return to FIG. 5, the second link 245 includes a first part 245a, a second part 245b, and a third part 245c located between the first part 245a and the second part 245b.

The fixing bracket 210 has a protruding post 245a2, and the protruding post 245a2 passes through a sliding groove 245a1 on the first linkage 243, so that the first part 245a can rotate or move along the sliding groove 245a1.

The third part 245c is pivoted on the plate 244 of the first link 242, and the second link 245 can rotate relative to the plate 244 of the first link 242 and move up and down with the plate 244 of the first link 242 .

The third link 247 includes a fourth part 247a and a fifth part opposite to each other. It is divided into 247b and a sixth portion 247c located between the fourth portion 247a and the fifth portion 247b.

The second part 245b of the second linkage 245 has a protrusion 245b2, which penetrates a sliding groove 247a1 on the fourth part 247a, so that the protrusion 245b2 of the second part 245b can rotate relative to the sliding groove 247a1 of the fourth part 247a And move. In this way, the third link 247 is linked with the second link 245. The sixth part 247c is pivoted on the fixing bracket 210.

The lifting member 230 has a protrusion 247b2 passing through a sliding groove 247b1 on the groove 212 and the fifth part 247b, so that the fifth part 247b is rotatably and slidably disposed in the sliding groove 245a1 and the groove 212. Therefore, the lifting member 230 can be driven by the third linking member 247 to move along the extending direction of the groove 212.

As shown in FIG. 4, when the first linkage 242 moves downward, the second linkage 245 is driven to rotate with the convex post 245a2 as the fulcrum, and the second linkage 245 then drives the third linkage 247 to use the sixth portion 247c as the fulcrum. Rotate. The rotation directions of the second link 245 and the third link 247 are opposite, so that the moving direction of the final lifting member 230 is opposite to the moving direction of the first link 242.

In this embodiment, the extending direction of the groove 212 is perpendicular to the extending direction of the first axis L. In other words, the moving direction of the lifting member 230 is perpendicular to the axis of rotation of the supporting frame 220 relative to the fixed bracket 210. Of course, the shape and direction of the groove 212 are not limited to the above.

In one embodiment, the distance between the first part 245a and the third part 245c of the second link 245 is smaller than the distance between the second part 245b and the third part 245c. Leave. In this way, when the movement of the first link 242 drives the second link 245 to rotate, the movement of the first link 242 will be enlarged by the lever, so that the movement range of the second part 245b of the second link 245 becomes Bigger.

Similarly, the distance between the fourth part 247a and the sixth part 247c of the third link 247 is smaller than the distance between the fifth part 247b and the sixth part 247c, so as to achieve the effect of lever enlargement, so that the first link 242 Even if there is only a slight movement, the fifth part 247b connected with the lifting member 230 can move up and down greatly after being amplified by the lever twice during the movement transmission process.

In addition, please refer back to FIG. 1. In this embodiment, when the fixing bracket 210 and the supporting frame 220 are located on the same plane, the combined shape and size of the fixing bracket 210 and the supporting frame 220 are the same or close to the first body 100. The size of is the same or close to the size of the second body 110.

Therefore, when the user wants to store the lifting device 10, the fixing bracket 210 and the supporting frame 220 are directly pivoted relative to the second body 110, and the fixing bracket 210 and the supporting frame 220 can completely cover the first body 100 and the second body. 110, which is similar to the state of the laptop when it is folded.

In this way, the fixing bracket 210 and the supporting bracket 220 can also be used as a shell to protect the first body 100. Of course, the relationship between the size and shape of the fixing bracket 210 and the supporting bracket 220 in this case and the size and shape of the first body 100 or the second body 110 is not limited by this.

In summary, when the lifting device of the present case can rotate relative to the fixed bracket through the support frame, the hinge assembly drives the linkage mechanism to move, so that the lifting member moves along the fixed support. The second side of the frame is raised. The lifting part itself can be a screen or an additional screen or an electronic body. Therefore, the lifting device of the present invention can effectively improve the comfort of the user through the above configuration.
