Detailed Description

Fig. 1 is a front perspective view of a lifting device according to an embodiment of the disclosure, and fig. 2 is a front perspective view of a support frame of the lifting device of fig. 1 after rotation.

Referring to fig. 1 and 2, the lifting device 10 of the present embodiment is suitable for being used with a first body 100 (shown by a dotted line, for example, a tablet computer), and may be used as a support or an expansion device for the first body 100, or may be used with a second body 110 (for example, a keyboard), so as to facilitate a user to input information to the first body 100.

In this embodiment, the lifting device 10 is adapted to lift the first body 100 to a suitable height, so that the user can operate the first body 100 at a more comfortable angle. As will be explained below.

The lifting device 10 includes a fixing bracket 210, a supporting bracket 220, a lifting member 230, a linkage mechanism 240 (fig. 3), and a hinge assembly 250.

As shown in fig. 2, the fixing bracket 210 has a first surface 210a, a second surface 210b, and a connection side 210 c. The hinge assembly 250 is located at the connecting side 210 c.

In the present embodiment, the hinge assembly 250 includes a first pivot element 252 and a second pivot element 254 pivotally connected to each other. The first pivoting member 252 is fixed to the fixing bracket 210, and the second pivoting member 254 is fixed to the supporting bracket 220, so that the supporting bracket 220 can rotate relative to the fixing bracket 210. Therefore, the fixing bracket 210 and the supporting bracket 220 can be used together as a supporting bracket. In addition, the hinge assembly further has a torsion member (not shown) for keeping the supporting frame 220 and the fixing bracket 210 from rotating arbitrarily under an unstressed condition.

Fig. 3 is a rear perspective view of a back shell hiding a fixing bracket of the lifting device of fig. 1, and fig. 4 is a rear perspective view of a back shell hiding a fixing bracket of the lifting device of fig. 2.

Referring to fig. 3 and 4, the linking mechanism 240 is disposed on the first surface 210a, and the linking mechanism 240 is linked to the second pivot element 254 and movably disposed on the other side of the fixed bracket 210 relative to the lifting element 230. In this embodiment, the linking mechanism 240 may be a multi-link mechanism or a gear assembly, which is not limited to the above.

The lifting member 230 is movably disposed on the second surface 210 b. The fixing bracket 210 further has a groove 212, and the groove 212 is located through the fixing bracket 210, so that the lifting member 230 can pass through the fixing bracket 210 and be linked to the linking mechanism 240, and the linking mechanism 240 can drive the lifting member 230 to move up and down. Referring back to fig. 2, the fixing bracket 210 has a groove 214, and the lifting member 230 is movably disposed in the groove 214 and driven by the linking mechanism 240 to move up and down along the second surface 210b of the fixing bracket 210.

In the process that the supporting frame 220 rotates backward relative to the fixing frame 210, the second pivoting member 254 drives the linking mechanism 240, so that the lifting member 230 is further lifted along the second surface 210b of the fixing frame 210.

In one embodiment, the lifting member 230 is a structure for fixing the first body 100, and the first body 100 can be fixed to the lifting member 230 and move up and down with the lifting member 230.

In an embodiment, a first magnetic attraction element 232 may be embedded in the lifting element 230, a second magnetic attraction element 102 may be embedded on a side of the first body 100 close to the lifting element 230, and the first magnetic attraction element 232 and the second magnetic attraction element 102 attract each other, so that the first body 100 is fixed on the lifting element 230. The first magnetic element 232 and the second magnetic element 102 can be magnets with opposite magnetism, or can be a combination of magnets and metal.

Of course, in other embodiments, the housing of the first body 100 near the side of the lifting element 230 may also be made of a metal material and is absorbed by the first magnetic attraction element 232, or the lifting element 230 itself is made of a metal material and is absorbed by the second magnetic attraction element 102, which is not limited to the above.

In addition, in other embodiments, the lifting element 230 and the first body 100 may be fixed by other methods such as a snap, or other combination.

In one embodiment, the lifting member 230 itself may also be a screen or other electronic components (e.g., a speaker), that is, when the user faces the supporting frame 220 toward the first side 210a, the screen (the lifting member 230 itself) is lifted along the second side 210b by the fixing frame 210, and the device is directly operated as a notebook computer. The kind of the lift 230 is not limited thereto.

Figure 5 is an exploded view of the lifting device of figure 1. Referring to fig. 3 to fig. 5, in the present embodiment, the linking mechanism 240 further includes a first linking member 242, a second linking member 245 and a third linking member 247 that are linked in sequence. The first link 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 linking member 245 and the third linking member 247 are two links, for example.

Fig. 6 is a partial cross-sectional view of fig. 1. Referring to fig. 5 and 6, the hinge assembly 250 further includes a driving member 256 extending from the second pivoting member 254. As shown in fig. 6, the driver 256 is disposed at a position offset from the first axis L of the second pivot 254, and is fixed to the shaft body 243 of the first link 242 of the link mechanism 240. In the embodiment, the driver 256 may be a latch, but the type of the driver 256 is not limited thereto.

When the fixed bracket 210 and the supporting bracket 220 are located on the same plane, the second axis R of the shaft body 243 fixed to the driving member 256 is coaxial with the first axis L of the second pivoting member 254 (fig. 7). At this time, the driver 256 is located directly above the first axis L.

Fig. 7 is a partial cross-sectional view of fig. 2. Referring to fig. 7, when the supporting frame 220 rotates relative to the fixed frame 210 instead of being located on the same plane, the second pivoting member 254 rotates with the driving member 256, and at this time, the driving member 256 rotates to the lower right of the first axis L in fig. 7, and the shaft body 243 fixed to the driving member 256 moves to the lower right along 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 is not coaxial but staggered from the first axis L.

When the supporting frame 220 rotates backward relative to the fixed frame 210, the first linking member 242 slightly moves downward along the first surface 210a of the fixed frame 210, so as to actuate the movement of the second linking member 245 and the third linking member 247.

Referring back to fig. 5, the second linking member 245 includes a first portion 245a, a second portion 245b and a third portion 245c between the first portion 245a and the second portion 245 b.

The fixed bracket 210 has a protruding pillar 245a2, and the protruding pillar 245a2 is disposed through the sliding slot 245a1 of the first linking member 243, so that the first portion 245a can rotate and move along the sliding slot 245a 1.

The third portion 245c is pivotally disposed on the plate 244 of the first linking member 242, and the second linking member 245 can rotate relative to the plate 244 of the first linking member 242 and move up and down along with the plate 244 of the first linking member 242.

The third linkage 247 includes a fourth portion 247a, a fifth portion 247b and a sixth portion 247c between the fourth portion 247a and the fifth portion 247 b.

The second portion 245b of the second linking member 245 has a protruding post 245b2 passing through the sliding slot 247a1 of the fourth portion 247a, so that the protruding post 245b2 of the second portion 245b can rotate and move relative to the sliding slot 247a1 of the fourth portion 247 a. Thus, the third linking member 247 links with the second linking member 245. The sixth section 247c is pivotally mounted to the mounting bracket 210.

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

As shown in fig. 4, when the first linking member 242 moves downward, the second linking member 245 is driven to rotate around the convex pillar 245a2, and the second linking member 245 drives the third linking member 247 to rotate around the sixth portion 247 c. The second linkage 245 rotates in the opposite direction to the third linkage 247, so that the moving direction of the final lifting member 230 is opposite to the moving direction of the first linkage 242.

In the present 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 rotating axis when the supporting frame 220 rotates relative to the fixing 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 portion 245a and the third portion 245c of the second linking member 245 is smaller than the distance between the second portion 245b and the third portion 245 c. In this way, when the movement of the first linking member 242 drives the second linking member 245 to rotate, the movement of the first linking member 242 will make the movement range of the second portion 245b of the second linking member 245 become larger due to the lever amplification effect.

Similarly, the distance between the fourth portion 247a and the sixth portion 247c of the third linkage member 247 is smaller than the distance between the fifth portion 247b and the sixth portion 247c, so as to achieve the effect of lever amplification, so that even though the first linkage member 242 only slightly moves, the first linkage member is twice lever-amplified in the motion transmission process, and finally the fifth portion 247b connected to the lifting member 230 can move up and down greatly.

In addition, referring back to fig. 1, in the embodiment, when the fixing bracket 210 and the supporting bracket 220 are located on the same plane, the shape and size of the fixing bracket 210 and the supporting bracket 220 are the same as or close to the size of the first body 100 and 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 bracket 220 are directly pivoted together relative to the second body 110, so that the fixing bracket 210 and the supporting bracket 220 can completely cover the first body 100 and the second body 110, similar to the state of the laptop when being stored.

In this way, the fixing bracket 210 and the supporting bracket 220 can also serve as a housing 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 and the size and shape of the first body 100 or the second body 110 is not limited thereto.

In summary, when the lifting device of the present disclosure can rotate relative to the fixed bracket through the supporting frame, the hinge assembly drives the linking mechanism to move, so that the lifting member is lifted along the second surface of the fixed bracket. The lifting element itself can be a screen or a carrier for an additional screen or an electronic body. Therefore, the lifting device can effectively improve the use comfort of a user through the configuration.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
