Description

Notebook computer

Technical Field

The embodiment of the invention relates to a notebook computer, in particular to a notebook computer with a lifting mechanism capable of being linked with a rotating shaft mechanism.

Background

The conventional notebook computer includes a host, a screen and a rotating shaft mechanism. The screen rotates relative to the host machine through the rotating shaft mechanism, and the screen can incline relative to the host machine through the rotating shaft mechanism, so that a user can watch the screen conveniently.

Due to the development of the thinning of the notebook computer, the thickness of the notebook computer is thinner and thinner, so that the heat dissipation space in the notebook computer, the heat dissipation structure and the size of the fan are limited. Therefore, when the notebook computer is operated at a high speed, the heat dissipation air flow inside the notebook computer needs to be improved by greatly increasing the rotation speed of the fan.

However, when the heat dissipation air flow is insufficient, the heat sources such as the processing chip in the notebook computer cannot achieve the required heat dissipation efficiency, resulting in the excessively high temperature of the processing chip. At this time, the notebook computer may reduce the operation speed of the processing chip to prevent the processing chip from being damaged, thereby resulting in a defect of reduced performance.

Accordingly, while current notebook computers meet the objectives of their use, many other needs have not been met. Accordingly, there is a need to provide improvements in notebook computers.

In the above figures, the notebook computer 1 is in a closed state.

The host 10 further includes a base 13 disposed in the housing 11. The base 13 may have an arcuate slot 132 (shown in fig. 6A). The base 13 may be locked in the housing 11 via a locking element (not shown). In some embodiments, the base 13 may be integrally formed with the housing 11.

The spindle mechanism 30 includes a rotary member 31, a torsion assembly 32, and a fixing member 33. The rotary member 31 is fixed to the screen 20 and rotates with respect to the arc-shaped groove 132. The rotating element 31 includes a rotating body 311 and an arc portion 312.

The rotating body 311 is fixed to the rear side 212 of the screen 20. The arc portion 312 is connected to the rotating body 311. In some embodiments, the rotating body 311 and the arc portion 312 may be integrally formed. The arcuate portion 312 is positioned within the arcuate slot 132. As shown in fig. 6A, when the screen 20 rotates relative to the main body 10, the arc portion 312 rotates along an arc path P1 relative to the arc groove 132. In the present embodiment, the arc-shaped groove 132 and the arc-shaped portion 312 are C-shaped.

In some embodiments, the arcuate path P1 may be a circular path. A main axis AX1 passes through the center of the arcuate path P1. The arcuate path P1 lies on a plane perpendicular to the main axis AX1. In the present embodiment, the arc portion 312 is rotatable about the main axis AX1 with respect to the arc groove 132. In other words, the screen 20 can rotate with respect to the host computer 10 centering on the main axis AX1.

The torsion assembly 32 is connected to the rotating member 31 and the stationary member 33. Torsion assembly 32 is used to provide a torsion between host 10 and screen 20. The torsion assembly 32 includes a first pivot 321, a torsion member 322, a connecting member 323, and a second pivot 324.

The first pivot 321 is connected to the connecting element 323 and the fixing element 33. The first pivot 321 extends along a first axis AX 2. The first axis AX2 is parallel to the main axis AX1. In this embodiment, the first pivot 321 is pivotally connected to the fixing element 33. The first pivot 321 is rotatable about the first axis AX2 with respect to the fixed element 33. In addition, the first pivot 321 rotates with the connecting element 323.

The first pivot 321 may include a first pivot portion 3211, a first stop portion 3212, and a first limiting portion 3213. The first pivot portion 3211 may be a circular column passing through the fixing element 33. The first stopper portion 3212 is connected to the first pivot portion 3211 and the first limiting portion 3213. The first restraining portion 3213 penetrates the connecting element 323.

The torsion element 322 is disposed at the first pivot portion 3211 of the first pivot 321, and is configured to provide a first torsion force between the first pivot 321 and the fixing element 33. The torsion member 322 can clamp the fixing member 33 between the torsion member 322 and the first stop portion 3212. The torsion member 322 may be an annular member, and the first pivot portion 3211 passes through the center of the torsion member 322.

The connecting element 323 is disposed at the first limiting portion 3213 of the first pivot 321 and can abut against the first stop portion 3212. The connecting element 323 may extend perpendicular to the first axis AX2, in other words the connecting element 323 may be perpendicular to the first pivot 321.

The connecting element 323 has a first connecting hole 3231 and a second connecting hole 3232. The first limiting portion 3213 of the first pivot 321 may pass through the first connection hole 3231 and may move along the first connection hole 3231. Further, the first connecting hole 3231 restricts rotation of the connecting element 323 with respect to the first restricting portion 3213. In other words, the connecting element 323 cannot rotate relative to the first pivot 321.

In some embodiments, the maximum length of the first connection hole 3231 is greater than 1.1 times the maximum width of the first pivot 321. The maximum length and the maximum thickness are measured in the same direction perpendicular to the first axis AX 2.

In some embodiments, the maximum width of the first connecting hole 3231 is substantially equal to the maximum thickness of the first pivot 321. The maximum width and the maximum width are measured in the same direction perpendicular to the first axis AX 2.

The second pivot 324 is connected to the connecting element 323 and the rotating element 31, and extends parallel to the first pivot 321. In this embodiment, the second pivot 324 extends along a second axis AX 3. The second axis AX3 is parallel to the first axis AX2 and the main axis AX1.

The second pivot 324 includes a second pivot portion 3241 and a second limiting portion 3243. The second pivot portion 3241 is pivoted to the connecting element 323 and passes through the second connecting hole 3232. In other words, the second pivot 324 is rotatable relative to the connecting element 323. In this embodiment, the connecting element 323 can provide a second torque force to the second pivot 324.

The second limiting portion 3243 is connected to the second pivot portion 3241 and is connected to the arc portion 312. In the present embodiment, the second limiting portion 3243 is fixed to the connecting end 313 of the arc portion 312, so that the second pivot 324 moves and rotates along with the arc portion 312. In some embodiments, the second pivot 324 cannot rotate relative to the arcuate portion 312.

The fixing element 33 is connected to the torsion assembly 32 and is fixed in the housing 11. In this embodiment, the fixing element 33 may be fixed to the base 13. The fixing element 33 may include a first plate 331 and a second plate 332. The first plate 331 may extend along a plane perpendicular to the first axis AX 2. In other words, the first plate 331 may be perpendicular to the first pivot 321. The second plate 332 extends perpendicular to the first plate 331.

As shown in fig. 2 to 4, in the present embodiment, the notebook computer 1 further includes a first arc cover 40 and a second arc cover 50. The first and second

arc cover plates

40, 50 cover the

rear sides

112, 212 of the screen 20 and the host 10.

As shown in fig. 4 and 6B, the first arc-shaped cover 40 and the second arc-shaped cover 50 are connected to or fixed to the rotating body 311 of the rotating member 31. The first arc-shaped cover plate 40 and the second arc-shaped cover plate 50 extend along the extending direction D1, and a cross section perpendicular to the extending direction D1 is arc-shaped. The first and second

arc cover plates

40 and 50 are spaced apart and parallel to each other. A gap G1 is formed between the first arc cover 40 and the second arc cover 50.

As shown in fig. 6B, the notebook computer 1 further includes a transmission line W1 connected to the host 10 and the screen 20 and adjacent to the first arc cover 40 and the second arc cover 50. The transmission line W1 is located in the gap G1.

The first arcuate cover 40 and/or the second arcuate cover 50 may match the shape of the rotating element 31. Therefore, the first arc cover 40 and/or the second arc cover 50 of the present disclosure can provide the rear side 112 of the notebook computer 1 with a better appearance, and can well configure the transmission line W1.

As shown in fig. 6A and 6B, the notebook computer 1 is in a covering state, and the screen 20 covers the host 10. At this time, the connection end 313 of the arc-shaped portion 312 of the rotating member 31 is located in the arc-shaped groove 132 of the base 13. A protective cover 14 of the housing 11 is located on the operating surface 111 of the housing 11. The protective cover 14 is pivotally connected to the housing 11.

Fig. 7 is a schematic cross-sectional view of the notebook computer 1 according to the present disclosure in some embodiments, wherein the notebook computer 1 is in a use state. The user may rotate the screen 20 with respect to the host 10 to tilt the screen 20 with respect to the host 10. At this time, the connection end 313 is separated from the arc groove 132 and exposed to the base 13. The connecting end 313 drives the second pivot 324 to move. In addition, the second pivot 324 drives the connecting element 323 to rotate around the first pivot 321.

When the notebook computer 1 is in a use state, the connecting end 313 and the connecting element 323 can protrude from the operation surface 111 of the casing 11. The connecting element 323 can push the protective cover 14 to tilt relative to the operating surface 111. In some embodiments, electronic components (e.g., microphone, antenna, camera) may be provided on the protective cover 14.

Therefore, by the rotating shaft structure of the present disclosure, the screen 20 can be rotated relative to the host 10 via the rotating shaft mechanism 30, and the rear side of the notebook computer 1 can be more beautiful.

In this embodiment, the host 10 further includes a lifting mechanism 15 and a foot pad 16. The lifting mechanism 15 is disposed within the housing 11 and is accessible through a bottom surface 113 of the housing 11. The lifting mechanism 15 may be connected to the first limiting portion 3213 of the first pivot 321 and may be connected to the foot pad 16. When the screen 20 is rotated relative to the host 10, the first pivot 321 drives the lifting mechanism 15 such that the lifting mechanism 15 changes the distance between the top ends 161 of the footpads 16 relative to the bottom surface 113. In this embodiment, the lifting mechanism 15 may be a mechanical lifting mechanism. In some embodiments, the lifting mechanism 15 may be an electric lifting mechanism.

As shown in fig. 4, 5, 6A and 6B, the lifting mechanism 15 further includes a gear 151 and a rack 152. The first limiting portion 3213 passes through the center of the gear 151, and the gear 151 may be fixed to the first limiting portion 3213. In other words, the gear 151 rotates following the first limiting portion 3213. The rack 152 is engaged with the gear 151. Racks 152 may pass through housing 11 to connect to footpads 16.

The foot pad 16 is disposed outside the housing 11 and adjacent to the bottom surface 113 of the housing 11. Foot pads 16 may be connected to the lifting mechanism 15. The bottom surface 113 is opposite to the operation surface 111 and may be substantially parallel to the operation surface 111.

In this embodiment, the footpad 16 has a top end 161 and a bottom end 162. The top end 161 is remote from the bottom surface 113, and the bottom end 162 may be secured to the bottom surface 113 of the housing 11. In some embodiments, the bottom end 162 of the footpad 16 contacts the bottom surface 113 of the housing 11.

As shown in fig. 6A and 6B, the notebook computer 1 is in a covering state, and the screen 20 covers the host 10. When the screen 20 is in a covering position, the rack 152 can contact the foot pad 16, and a first distance d1 is provided between the top 161 and the bottom 113 of the foot pad 16.

When the host computer 10 is placed on a reference plane R1, the footpad 16 contacts the reference plane R1. In other words, the bottom surface 113 adjacent to the rear side 112 has a first distance d1 from the reference plane R1.

As shown in fig. 7, the notebook computer 1 is in a use state. When the user rotates the screen 20 with respect to the host 10, the screen 20 is tilted with respect to the host 10. At this time, the first pivot 321 rotates and drives the gear 151 to rotate. When the gear 151 rotates, the rack 152 is driven to move, so that one end of the rack 152 abuts against the foot pad 16 to change the distance between the top end 161 and the bottom surface 113.

The distance between the top end 161 and the bottom surface 113 gradually increases during the movement of the screen 20 from a covering position to a use position, and the distance between the top end 161 and the bottom surface 113 gradually decreases during the movement of the screen 20 from the use position to the covering position.

In this embodiment, when the screen 20 is in the use position, the rack 152 abuts against the foot pad 16 so that the top end 161 has a second distance d2 with respect to the bottom surface 113, wherein the second distance d2 is greater than the first distance d1. In other words, the bottom surface 113 of the back side 112 of the host 10 has the second distance d2 from the reference plane R1, thereby increasing the inclination angle between the host 10 and the reference plane R1.

Thus, the distance between the top ends 161 of the footpads 16 relative to the bottom surface 113 may be varied by the lifting mechanism 15 as the screen 20 is rotated relative to the host 10. In addition, when the screen 20 is in the covering position, the distance between the top end 161 of the foot pad 16 and the bottom surface 113 is reduced, so that the overall thickness of the notebook computer 1 can be reduced to meet the requirement of the user on the thickness of the notebook computer 1.

In addition, when the screen 20 is in the covering position, the distance between the top ends 161 of the footpads 16 at the rear side 112 of the host 10 relative to the bottom surface 113 increases. Therefore, as shown in fig. 7, when the host 10 is placed on a reference plane R1, the space between the rear side 112 of the housing 11 and the reference plane R1 can be further increased by the foot pad 16, so as to further increase the heat dissipation efficiency of the notebook computer.

Fig. 8 is a perspective view of the spindle mechanism 30 and lifting mechanism 15 of the present disclosure in accordance with some embodiments. Fig. 9 is an exploded view of the spindle mechanism 30 and lifting mechanism 15 of the present disclosure in some embodiments. Fig. 10 is a schematic cross-sectional view of a notebook computer 1 according to the present disclosure in some embodiments. In the above figures, the notebook computer 1 is in a closed state.

In this embodiment, the lifting mechanism 15 includes a gear set 153, a cam 154 and an auxiliary pivot 155. Gear set 153 is coupled to first pivot 321. Cam 154 is connected to gear set 153 and contacts footpad 16. When the screen 20 rotates relative to the host 10, the gear set 153 drives the cam 154 to rotate.

In this embodiment, the gear set 153 may include a first gear 1531 and a second gear 1532. The first pivot 321 passes through the center of the first gear 1531, and the first gear 1531 may be fixed to the first pivot 321. The auxiliary pivot 155 passes through the center of the second gear 1532 and passes through the cam 154. The second gear 1532 and the cam 154 may be fixed to the auxiliary pivot 155. One end of the auxiliary pivot 155 may be pivotally connected to the base 13. In other words, the gear 151 rotates following the first pivot 321, and the cam 154 rotates following the second gear 1532.

As shown in fig. 10, the notebook computer 1 is in a covering state, and the screen 20 covers the host 10. When the screen 20 is in a covering position, the cam 154 may contact the foot pad 16, and a first distance d1 is provided between the top 161 and the bottom 113 of the foot pad 16.

As shown in fig. 11, the notebook computer 1 is in a use state. When the user rotates the screen 20 with respect to the host 10, the screen 20 is tilted with respect to the host 10. At this time, the first pivot 321 rotates and drives the first gear 1531 to rotate. When the first gear 1531 rotates, the second gear 1532 and the cam 154 are driven to rotate, such that the protruding portion 1541 of the cam 154 abuts against the foot pad 16 to change the distance between the top end 161 and the bottom surface 113.

In the present embodiment, when the screen 20 is in the use position, the protruding portion 1541 of the cam 154 abuts against the foot pad 16, so that the top end 161 has a second distance d2 from the bottom surface 113, and the inclination angle between the host 10 and the reference plane R1 is increased.

While the present disclosure has been disclosed in terms of various embodiments, it is to be understood that such embodiments are by way of example only and are not intended to limit the scope of the disclosed embodiments, as many variations and modifications are possible to those skilled in the art without departing from the spirit and scope of the disclosed embodiments. The above embodiments are therefore not intended to limit the scope of the embodiments of the present disclosure, which is defined by the appended claims.
