Description

Notebook computer

Technical Field

The present invention relates to a notebook computer, and more particularly, to a notebook computer having a support member protruding from or retracting into a base by rotation of a display.

Background

At present, notebook computers have been widely used in daily life of people. In the trend that the existing high-efficiency notebook computer is lighter and thinner, it is difficult to give consideration to good heat dissipation. Therefore, some notebook computers use the lifting mechanism to lift the base, so as to improve the heat dissipation problem. However, the existing lifting mechanism is complex and relatively expensive to develop. In addition, the lifting mechanism is too bulky, occupies too much internal space of the notebook computer, and further compresses the setting space of other hardware. Moreover, in order to meet the heat dissipation standard requirement, the bottom of the base and the tabletop must reach a certain height, so that the foot pad at the rear part is too high, and the tabletop is very thick even if the machine body is designed to be thin. Furthermore, in order to meet the heat dissipation requirement of the conventional high-performance notebook computer, a plurality of heat dissipation holes need to be added on the appearance of the notebook computer, so that the notebook computer is not clean and simple in shape.

Disclosure of Invention

The present invention provides a notebook computer capable of driving a supporting member to protrude or retract into a base by rotation of a display, so as to solve the above-mentioned problems.

According to an embodiment of the present invention, a notebook computer includes a base, a display, a rotating shaft structure, a linking member, a supporting member and a transmitting member. The display is pivoted to the base through the rotating shaft structure. The linkage piece is arranged on the rotating shaft structure. The supporting member is movably disposed on the base. The transmission part is connected with the linkage part and the support part. When the display is unfolded or folded by rotating relative to the base, the rotating shaft structure drives the linkage member to rotate, and the linkage member drives the supporting member to move through the transmission member, so that the supporting member protrudes out of or retracts into the base.

In summary, when the display device rotates, the linking member and the transmission member on the rotating shaft structure are utilized to drive the supporting member to protrude or retract into the base, so that the base is lifted or lowered. When the display rotates relative to the base and is unfolded, the linkage member and the transmission member on the rotating shaft structure drive the supporting member to protrude out of the base, so that the base is lifted. At this moment, enough space is conveniently provided under the base to allow a large amount of cold air to enter from the bottom, so that the heat dissipation effect is improved. The lifting of the base can meet the bottom air inlet height required by the heat dissipation specification, so that the thick foot pad at the bottom of the existing notebook computer can be replaced, and the notebook computer has a light, thin and elegant appearance design. The lifting of the base also raises the display to provide a more comfortable reading angle for the user. The invention can also arrange a lower cover at the bottom of the base, and the heat radiation module (such as heat radiation fins, soaking plates and the like) is arranged in the base corresponding to the lower cover. When the supporting piece protrudes out of the base, the supporting piece drives the lower cover to open relative to the base. At this time, the heat dissipation module is exposed from the gap between the lower cover and the base to improve the heat dissipation effect. In addition, the heat dissipation holes can be hidden in the lower cover, when the display is unfolded relative to the base, the heat dissipation holes can be exposed after the lower cover is opened, and when the display is folded relative to the base, the heat dissipation holes can be hidden in the lower cover, so that the overall appearance of the notebook computer is simpler and more attractive. The assembly mode of the rotating shaft structure of the invention is the same as that of the rotating shaft structure of the existing notebook computer, so that additional assembly difficulty can not be caused. In addition, the rotating shaft structure, the linkage piece, the supporting piece and the transmission piece are simple in design, the development time is fast, and the research and development cost can be effectively reduced.

The advantages and spirit of the present invention can be further understood by the following detailed description of the invention and the accompanying drawings.

Detailed Description

Referring to fig. 1 to 5, fig. 1 is a side view of a notebook computer 1 according to an embodiment of the present invention, fig. 2 is a side view of a display 12 in fig. 1 being unfolded relative to a base 10, fig. 3 is a side view of the display 12 in fig. 2 being continuously unfolded in a direction away from the base 10, fig. 4 is a combination diagram of a rotating shaft structure 14, a linkage 16, a support 18, a transmission member 20 and a bracket 22 according to an embodiment of the present invention, and fig. 5 is an exploded view of the rotating shaft structure 14, the linkage 16, the support 18, the transmission member 20 and the bracket 22 in fig. 4. It should be noted that, for convenience of describing the technical features of the present invention, the second fixing element 142 and the bracket 22 of the rotating shaft structure 14 shown in fig. 4 and 5 are omitted in fig. 1 to 3.

As shown in fig. 1 to 5, the notebook computer 1 includes a base 10, a display 12, a rotating shaft structure 14, a linking member 16, a supporting member 18, a transmitting member 20, a bracket 22 and a foot pad 24. Generally, the notebook computer 1 is further provided with software and hardware components necessary for operation, such as a circuit board, a processor, a memory, a power supply, an application program, a communication module, and the like, depending on the actual application.

The hinge structure 14 pivotally connects the display 12 to the base 10, such that the display 12 can be rotated relative to the base 10 to be unfolded (as shown in fig. 2 and 3) or folded (as shown in fig. 1). In practical applications, the hinge structure 14 can be a hinge (hinge), but not limited thereto. The linking member 16 is disposed on the rotating shaft structure 14, the supporting member 18 is movably disposed on the base 10, and the transmission member 20 is connected to the linking member 16 and the supporting member 18. Thus, when the monitor 12 rotates relative to the base 10 to be unfolded or folded, the rotating shaft structure 14 drives the linking member 16 to rotate, and the linking member 16 drives the supporting member 18 to move up and down via the transmission member 20, so that the supporting member 18 protrudes from or retracts into the base 10. As shown in fig. 2 and 3, when the supporting member 18 protrudes from the base 10, the supporting member 18 lifts the base 10. As shown in fig. 1, when the support member 18 is retracted into the base 10, the support member 18 lowers the base 10.

As shown in fig. 4 and fig. 5, the hinge structure 14 may include a first fixing member 140, a second fixing member 142 and a hinge member 144. The first fixing member 140 is connected to the rotating shaft member 144, and the rotating shaft member 144 is pivotally connected to the second fixing member 142. When the notebook computer 1 is assembled, the first fixing member 140 of the rotating shaft structure 14 is fixed to the display 12, and the second fixing member 142 of the rotating shaft structure 14 is fixed to the base 10, so that the rotating shaft structure 14 pivotally connects the display 12 to the base 10. The hinge structure 14 of the present invention is assembled in the same manner as the hinge structure of the notebook computer, so that no additional difficulty is caused in assembly.

In this embodiment, the rotating shaft 144 may have a special-shaped shaft 1440, and the linking member 16 may have a special-shaped hole 160. The shaped shaft 1440 of the rotating shaft 144 is disposed in the shaped hole 160 of the linkage 16, such that the linkage 16 can rotate along with the rotating shaft 144. Thus, when the monitor 12 rotates relative to the base 10 to be unfolded or folded, the rotating shaft 144 drives the linking member 16 to rotate.

The bracket 22 is disposed on the rotating shaft element 144 of the rotating shaft structure 14, and the transmission element 20 is pivoted to the bracket 22. In the present embodiment, the bracket 22 may have a guiding portion 220, and the supporting member 18 may have a guiding groove 180. The guide part 220 is disposed in the guide groove 180. By the cooperation of the guiding portion 220 and the guiding groove 180, the transmission member 20 can drive the supporting member 18 to move up and down stably. In this embodiment, the two brackets 22 may be disposed on two sides of the linking member 16, the supporting member 18 and the transmission member 20, each bracket 22 has a guiding portion 220, and two sides of the supporting member 18 have two corresponding guiding grooves 180. The foot pad 24 is attached to the support member 18. In this embodiment, the foot pads 24 may be removably attached to the support member 18 for ease of assembly.

In this embodiment, the linking component 16 may have a first gear portion 162, the transmission component 20 may have a second gear portion 200 and a third gear portion 202, and the supporting component 18 may have a rack 182. As shown in fig. 1, when the display 12 is folded with respect to the base 10, the first gear portion 162 of the linking member 16 is engaged with the second gear portion 200 of the transmission member 20, and the third gear portion 202 of the transmission member 20 is engaged with the rack 182 of the supporting member 18. As shown in fig. 2, when the display 12 rotates to an angle θ 1 relative to the base 10 and is unfolded, the rotating shaft 144 of the rotating shaft structure 14 drives the linking member 16 to rotate. At this time, by the mutual cooperation of the first gear portion 162, the second gear portion 200, the third gear portion 202 and the rack 182, the linking member 16 drives the supporting member 18 to move downward through the transmission member 20, so that the supporting member 18 protrudes out of the base 10, and the base 10 is lifted to the height H.

As shown in fig. 3, when the display 12 continues to rotate to the angle θ 2 away from the base 10 and unfold, the first gear portion 162 of the linkage 16 is separated from the second gear portion 200 of the transmission member 20. Therefore, when the display 12 rotates from the angle θ 1 shown in fig. 2 to the angle θ 2 shown in fig. 3, the base 10 is still maintained at the height H. Therefore, when the user finely adjusts the unfolding angle of the display 12 between the angle θ 1 and the angle θ 2, the height of the base 10 is not changed. The angle θ 1 may be 81 degrees, and the angle θ 2 may be 130 degrees, but not limited thereto. The angles θ 1 and θ 2 can be determined according to practical applications.

When the notebook computer 1 is not in use, the user can rotate the display 12 relative to the base 10 to fold. When the display 12 rotates from the angle θ 2 shown in fig. 3 to the angle θ 1 shown in fig. 2, the first gear portion 162 of the linking member 16 is not yet meshed with the second gear portion 200 of the transmission member 20, and the base 10 is still maintained at the height H. When the monitor 12 rotates toward the base 10 and is folded, the first gear portion 162 of the linking member 16 is engaged with the second gear portion 200 of the transmission member 20. At this time, by the cooperation of the first gear portion 162, the second gear portion 200, the third gear portion 202 and the rack 182, the linking member 16 drives the supporting member 18 to move upward via the transmission member 20, so that the supporting member 18 retracts into the base 10, and the base 10 is lowered, as shown in fig. 1.

Referring to fig. 6, fig. 6 is a bottom perspective view of a notebook computer 1 according to another embodiment of the present invention.

As shown in FIG. 6, the bottom of the base 10 may have a plurality of heat dissipation holes 100. When the base 10 is lifted, there is enough room under the base 10 for a large amount of cold air to enter from the heat dissipation holes 100 at the bottom, so as to enhance the heat dissipation effect.

Referring to fig. 7, fig. 7 is a side view of a notebook computer 1 according to another embodiment of the invention.

As shown in fig. 7, the notebook computer 1 may further include a bottom cover 26 and a heat dissipation module 28. The lower cover 26 may be pivotally connected to the bottom of the base 10 and connected to the support member 18. Therefore, when the supporting member 18 protrudes or retracts from the base 10, the supporting member 18 will drive the lower cover 26 to rotate relative to the base 10 to open or close. In addition, a heat dissipation module 28 is disposed in the base 10 corresponding to the lower cover 26. Therefore, when the lower cover 26 is opened relative to the base 10, a gap G is formed between the lower cover 26 and the base 10, so that the heat dissipation module 28 is exposed from the gap G. At this time, the heat dissipation module 28 can dissipate the heat in the base 10 from the gap G to the outside of the base 10, so as to enhance the heat dissipation effect. In the present embodiment, the heat dissipation module 28 may be a heat dissipation fin, a heat spreader or other heat dissipation components, depending on the application.

It should be noted that, in the present invention, the heat dissipation hole 100 shown in fig. 6 can be hidden in the lower cover 26 shown in fig. 7, when the display 12 is unfolded relative to the base 10, the heat dissipation hole 100 can be exposed only by opening the lower cover 26, and when the display 12 is folded relative to the base 10, the heat dissipation hole 100 can be hidden in the lower cover 26, so that the overall appearance of the notebook computer 1 is more simple and beautiful.

Referring to fig. 8, fig. 8 is a side view of a transmission member 20 according to another embodiment of the invention.

As shown in fig. 8, third gear portion 202 of transmission member 20 may have a diameter greater than that of second gear portion 200 of transmission member 20. When the linking member 16 drives the transmission member 20 to rotate through the cooperation between the first gear portion 162 and the second gear portion 200, the transmission member 20 can drive the supporting member 18 to move for a longer stroke through the cooperation between the third gear portion 202 and the rack 182.

Referring to fig. 9, fig. 9 is a side view of a transmission member 20 according to another embodiment of the present invention.

As shown in fig. 9, the transmission member 20 may include a plurality of

first gears

20a, 20b, 20c and a second gear 20d, wherein the plurality of

first gears

20a, 20b, 20c are meshed with each other, one of the plurality of

first gears

20a, 20b, 20c (i.e., the first gear 20 a) is meshed with the first gear portion 162 of the linkage 16, another one of the plurality of

first gears

20a, 20b, 20c (i.e., the first gear 20 c) is coaxial with the second gear 20d, and the second gear 20d is meshed with the rack 182 of the supporting member 18. Therefore, when the linking member 16 rotates, the supporting member 18 is driven by the

first gears

20a, 20b, 20c and the second gear 20d to move up and down. In the present embodiment, the diameter of the second gear 20d is larger than the diameter of the

first gears

20a, 20b, 20 c. When the linking member 16 drives the second gear 20d to rotate through the cooperation of the first gear portion 162 and the

first gears

20a, 20b, and 20c, the second gear 20d can cooperate with the rack 182 to drive the supporting member 18 to move for a longer stroke.

In summary, when the display device rotates, the linking member and the transmission member on the rotating shaft structure are utilized to drive the supporting member to protrude or retract into the base, so that the base is lifted or lowered. When the display rotates relative to the base and is unfolded, the linkage piece and the transmission piece on the rotating shaft structure can drive the supporting piece to protrude out of the base, so that the base is lifted. At the moment, enough space is conveniently provided under the base to allow a large amount of cold air to enter from the bottom, so that the heat dissipation effect is improved. The lifting of the base can meet the bottom air inlet height required by the heat dissipation specification, so that the thick foot pad at the bottom of the existing notebook computer can be replaced, and the notebook computer has a light, thin and elegant appearance design. The lifting of the base also raises the display to provide a more comfortable reading angle for the user. The invention can also arrange a lower cover at the bottom of the base, and the heat dissipation module (such as heat dissipation fins, vapor chamber and the like) is arranged in the base corresponding to the lower cover. When the supporting piece protrudes out of the base, the supporting piece drives the lower cover to open relative to the base. At this time, the heat dissipation module is exposed from the gap between the lower cover and the base, so as to improve the heat dissipation effect. In addition, the heat dissipation holes can be hidden in the lower cover, when the display is unfolded relative to the base, the heat dissipation holes can be exposed after the lower cover is opened, and when the display is folded relative to the base, the heat dissipation holes can be hidden in the lower cover, so that the overall appearance of the notebook computer is simpler and more attractive. The assembly mode of the rotating shaft structure of the invention is the same as that of the rotating shaft structure of the existing notebook computer, so that additional assembly difficulty can not be caused. In addition, the rotating shaft structure, the linkage piece, the supporting piece and the transmission piece are simple in design, the development time is fast, and the research and development cost can be effectively reduced.
