Description

FIELD OF THE INVENTION

The invention relates to an electronic device and a hinge assembly, particularly to an electronic device and a hinge assembly thereof.

DESCRIPTION OF RELATED ART

In a general clamshell electronic device such as a notebook computer or a mobile phone, a hinge assembly is usually used to pivotally connect a display and a main body of the electronic device. Also, a user may cause the two housings of the electronic device to open or close relative to each other through the hinge assembly, thereby making the electronic device ready for use or for storage.

In detail, a general hinge assembly provides the clamshell electronic device with a fixed output of torsional force, so that during opening or closing, the display and the main body are prevented from generating different torsional forces when in different opening or closing positions. However, there is a possibility that that the display cannot be stably fixed in a predetermined position due to insufficient torsional force from the hinge assembly, or that a force from the user to rotate the display to the opening position cannot be buffered. In addition, during the process of rotating the display from the closing position to the opening position, the user may also experience difficulty smoothly opening the display due to excessive torsional force.

DETAILED DESCRIPTION OF DISCLOSED EMBODIMENTS

First Embodiment

FIG. 1 is a schematic view of an electronic device according to the invention, FIG. 2 is a schematic exploded view of a hinge assembly of a first embodiment of the electronic device in FIG. 1, and FIG. 3 is a schematic view illustrating assembly of the hinge assembly in FIG. 2. Referring to FIG. 1, FIG. 2 and FIG. 3 together, an electronic device 1000 of the present embodiment is a notebook computer including a first housing 100, a second housing 200 and a hinge assembly 300, wherein the first housing 100 includes a first display part 110, the second housing 200 includes a second display part 210 or a keyboard part, and the hinge assembly 300 is connected between the first housing 100 and the second housing 200, so that the first housing 100 can be opened or closed relative to the second housing 200.

The hinge assembly 300 includes a first fixed block 310, a second fixed block 320, a first connecting rod 330, a second connecting rod 340, at least one damper rod 392 and at least one fastener 394. The first fixed block 310 has a first end 311 and a second end 312, and the first end 311 of the first fixed block 310 is attached to the first housing 100. The second fixed block 320 has a third end 321 and a fourth end 322, and the third end 321 of the second fixed block 320 is attached to the second housing 200. The first connecting rod 330 has a fifth end 331 and a sixth end 332, wherein the fifth end 331 is slidably and rotatably connected to the second end 312 of the first fixed block 310, and the sixth end 332 is rotatably or swingably connected to the fourth end 322 of the second fixed block 320. The second connecting rod 340 has a seventh end 341 and an eighth end 342, wherein the seventh end 341 is slidably and rotatably connected to the fourth end 322 of the second fixed block 320, and the eighth end 342 is rotatably or swingably connected to the second end 312 of the first fixed block 310 and the sixth end 332 of the first connecting rod 330. The damper rod 392 is fixed to the first fixed block 310, wherein the damper rod 392 has an axial direction parallel to an assembly direction X of the first fixed block 310, the second fixed block 320, the first connecting rod 330 and the second connecting rod 340. The fastener 394 is fixed to the first fixed block 310, and a distal end (not denoted) of the damper rod 392 is fastened into the fastener 394, wherein the damper rod 392 may be driven by the first connecting rod 330 or the second connecting rod 340 to move relative to the fastener 394 along the axial direction.

In the present embodiment, there are disposed two damper rods 392 and two fasteners 394, wherein the fasteners 394 are fixed to two opposing sides of the first fixed block 310 and are hollow cylinders; one distal end (not denoted) of the damper rods 392 penetrates into the fasteners 394 corresponding thereto, and the other distal end 3921 of the damper rods 392 is linked to the first connecting rod 330. Thus, when the first connecting rod 330 moves relative to the first fixed block 310, the damper rods 392 are driven by the first connecting rod 330 to move relative to the fasteners 394 being hollow cylinders.

FIG. 4A and FIG. 4B are schematic views illustrating two embodiments of the damper rod 392 and the fastener 394. It can be seen from FIG. 4A that, in one embodiment, the fastener 394 being a hollow cylinder has a slit 3941, and the distal end of the damper rod 392 which is inserted into the fastener 394 has a wedge shape, wherein when the wedge-shaped distal end enters deeper into the fastener 394, the slit 3941 enables the entire fastener 394 to have ability to deform and thus provides a buffering function, thereby preventing the fastener 394 from being cracked and damaged due to the deep insertion of the distal end. It can be seen from FIG. 4B that, in another embodiment, the distal end of the damper rod 392 which is inserted into the fastener 394 similarly has a wedge shape, and the slit 3941 is provided at the distal end of the damper rod 392 for being inserted into the fastener 394. This slit 3941 allows room for deformation of the distal end. Thus, when the wedge-shaped distal end enters deeper into the fastener 394, by the slit 3941, the distal end is deformed according to an inner shape of the fastener 394, thereby preventing the fastener 394 from being expanded by the distal end of the damper rod 392 and thus being cracked and damaged.

Referring then to FIG. 1, FIG. 2 and FIG. 3, following the above, the first connecting rod 330 and the second connecting rod 340 include a plurality of connecting rod members. In other words, the first connecting rod 330 and the second connecting rod 340 have the same size, structure and shape, wherein the connecting rod members which constitute the first connecting rod 330 are disposed in a direction opposite that in which the connecting rod members which constitute the second connecting rod 340 are disposed. In terms of the present embodiment, the first connecting rod 330 includes two connecting rod members and the second connecting rod 340 includes three connecting rod members. Each connecting rod member has a first shaft hole 333, a second shaft hole 334 and a third shaft hole 335. The first shaft hole 333 is located on one distal end of the connecting rod member, and the second shaft hole 334 and the third shaft hole 335 are located on the other distal end of the connecting rod member.

In terms of the present embodiment, the fifth end 331 of the first connecting rod 330 has the first shaft hole 333, and the sixth end 332 of the first connecting rod 330 has the second shaft hole 334 and the third shaft hole 335; the seventh end 341 of the second connecting rod 340 has the first shaft hole 333, and the eighth end 342 of the second connecting rod 340 has the second shaft hole 334 and the third shaft hole 335. The hinge assembly 300 further includes a first fixed shaft 360, wherein the first fixed shaft 360 is inserted through the third shaft hole 335 of the eighth end 342 of the second connecting rod 340 and the second end 312. In this way, by the first fixed shaft 360, the second connecting rod 340 can be swung relative to the first fixed block 310.

In addition, the hinge assembly 300 further includes a second fixed shaft 370, and the second fixed shaft 370 is inserted through the third shaft hole 335 of the sixth end 332 of the first connecting rod 330 and the fourth end 322, so that the first connecting rod 330 can be swung relative to the second fixed block 320. In addition, the hinge assembly 300 further includes a third fixed shaft 380, and the third fixed shaft 380 passes through the second shaft holes 334 of the first connecting rod 330 and the second connecting rod 340. Thus, the first connecting rod 330 and the second connecting rod 340 can be swung relative to each other with the third fixed shaft 380 serving as an axis of swinging.

The hinge assembly 300 further includes a first sliding shaft 351 and a second sliding shaft 352, wherein the second end 312 has a pair of first sliding slots 313 and the fourth end 322 has a pair of second sliding slots 323, and the first sliding shaft 351 passes through the first sliding slots 313 and the first shaft hole 333 of the first connecting rod 330. Thus, while the first connecting rod 330 can be swung relative to the first fixed block 310, the first connecting rod 330 can also be translated relative to the first fixed block 310 by movement of the first sliding shaft 351 within the first sliding slots 313. Similarly, since the second sliding shaft 352 passes through the second sliding slots 323 and the first shaft hole 333 of the second connecting rod 340, while the second connecting rod 340 can be swung relative to the second fixed block 320, the second connecting rod 340 can also be translated relative to the second fixed block 320 by movement of the second sliding shaft 352 within the second sliding slots 323.

FIG. 5A to FIG. 5D are breakdown views illustrating a swinging operation of a first fixed block relative to a second fixed block. Referring to FIG. 2, FIG. 3 and FIG. 5A together, when the first housing 100 of the electronic device 1000 (shown in FIG. 1) is opened 180 degrees relative to the second housing 200, the first fixed block 310 attached to the first housing 100 is also opened 180 degrees relative to the second fixed block 320 attached to the second housing 200. At this moment, an upper surface 100a of the first housing 100 is coplanar with an upper surface 200a of the second housing 200 (as shown in FIG. 1). Moreover, the first sliding shaft 351 is located on the right side of the first sliding slot 313, and the second sliding shaft 352 is located on the left side of the second sliding slot 323. The upper surface 100a may be a display plane or a touch display plane, and the upper surface 200a may be a touch plane or another touch display plane. By the technical solution provided in the present case, a gap between the first housing 100 and the second housing 200 can be reduced to integrate the upper surface 100a with the upper surface 200a to obtain a larger plane.

Referring next to FIG. 5B, FIG. 5C and FIG. 5D, when the first housing 100 (shown in FIG. 1) of the electronic device 1000 (shown in FIG. 1) is closed relative to the second housing 200 (shown in FIG. 1), the first connecting rod 330 and the second connecting rod 340 are swung relative to each other with the third fixed shaft 380 serving as the axis of swinging. Meanwhile, by being pulled by the first housing 100, the second sliding shaft 352 translationally slides from the left side to the right side of the second sliding slot 323. Due to the relative swinging between the first fixed shaft 360, the second fixed shaft 370, the third fixed shaft 380, the first fixed block 310, the second fixed block 320, the first connecting rod 330 and the second connecting rod 340, and under limitations that the sixth end 332 of the first connecting rod 330 is rotatably fixed to the fourth end 322 of the second fixed block 320 by the second fixed shaft 370 and that the eighth end 342 of the second connecting rod 340 is rotatably fixed to the second end 312 of the first fixed block 310 by the first fixed shaft 360, during an overturn of the first housing 100 relative to the second housing 200, the first sliding shaft 351 translationally slides from the left side to the right side of the first sliding slot 313, and the damper rod 392 is driven by the first sliding shaft 351 to enter less deeply into the fastener 394 being a hollow cylinder. By matching the wedge-shaped distal end of the damper rod 392 with the fastener 394 being a hollow cylinder, a torsional force can be provided to fix the first housing 100 at a certain predetermined angle relative to the second housing 200.

Additionally, although the above description provides an example in which two damper rods 392 and two fasteners 394 being hollow cylinders are disposed on two opposing sides of the first fixed block 310, according to actual needs, persons skilled in the art may change where and how many damper rods 392 and hollow cylinders are disposed. For example, two damper rods 392 and two fasteners 394 may also be disposed on two opposing sides of the second fixed block 320. Further, it can be considered to dispose only one damper rod 392 and one fastener 394, and this damper rod 392 and this fastener 394 may be contained in a recess provided in the middle of the first fixed block 310 or the second fixed block 320. Although the structures of the corresponding first connecting rod 330, second connecting rod 340 and other elements are changed in accordance with this design, the same effect of providing torsional force to fix the first housing 100 at a certain predetermined angle relative to the second housing 200 can still be achieved.

Second Embodiment

FIG. 6A is a schematic exploded view of a hinge assembly of a second embodiment, and FIG. 6B is a schematic view of assembly of the hinge assembly in FIG. 6A. Referring to FIG. 6A and FIG. 6B together, the present embodiment is roughly the same as the aforesaid first embodiment and the same descriptions will be omitted. The present embodiment differs from the aforesaid first embodiment in that, in the present embodiment, the fastener 394 is a C-shaped buckle ring instead of a hollow cylinder, and the numbers of the C-shaped buckle ring and the damper rod 392 are both four. The hinge assembly 300 further includes two fixed plates 396, wherein one pair of the C-shaped buckle rings are integrally formed and disposed between one of the fixed plates 396 and the first fixed block 310, and the other pair of the C-shaped buckle rings are integrally formed and disposed between the other of the fixed plates 396 and the second fixed block 320. The damper rods 392 passes through the first fixed block 310 or the second fixed block 320 corresponding thereto, the C-shaped buckle rings, and the fixed plates 396 corresponding thereto. Similarly, a distal end of the damper rods 392 is linked to the first sliding shaft 351 and the second sliding shaft 352, and the other distal end 3921 (shown in FIG. 2) of the damper rods 392 is fastened into the C-shaped buckle rings.

In addition, the third shaft hole 335 of the present embodiment may be composed of a C-shaped ring, and the C-shaped ring may similarly allow the insertion of the first fixed shaft 360 or the second fixed shaft 370 therethrough so that the first connecting rod 330 and the second connecting rod 340 can be rotatably fixed to the second fixed block 320 and the first fixed block 310 corresponding thereto.

Following the above, when the first housing 100 is swung relative to the second housing 200, the translational sliding of the first sliding shaft 351 within the first sliding slot 313 and the translational sliding of the second sliding shaft 352 within the second sliding slot 323 drive the damper rods 392 to move relative to the C-shaped buckle rings. Similarly to the slit 3941 in the aforesaid first embodiment, the C-shaped buckle rings provide room for elastic deformation. Therefore, by matching the C-shaped buckle rings and the damper rods 392 with each other, sufficient torsional force can be provided to fix the first housing 100 and the second housing 200 at predetermined angles.

In summary, in the electronic device and the hinge assembly thereof according to the invention, by matching the damper rod and the fastener with each other, the torsional force provided to fix the first housing at a predetermined angle relative to the second housing can be adjusted according to an angle between the first housing and the second housing. Meanwhile, deformation of the fastener can be allowed by the slot of the fastener so that a reaction force caused by an increasing interference between the damper rod and the fastener can be regulated. Thus, the structure can be maintained intact.

Although the invention has been described with reference to the above embodiments, it will be apparent to one of ordinary skill in the art that modifications to the described embodiments may be made without departing from the spirit of the invention. Accordingly, the scope of the invention will be defined by the attached claims and not by the above detailed descriptions.
