Description

Notebook computer and its shaft mechanism

technical field

The present invention relates to a notebook computer, in particular to a notebook computer with a rotating shaft mechanism for opening the light and closing the weight.

Background technique

Referring to FIG. 1 , a rotating shaft mechanism (not shown) is provided between the screen 32 and the base 31 of the notebook computer, so that the screen 32 can rotate relative to the base 31 . At present, the operating torque required by the rotating shaft mechanism is a fixed value, which is illustrated by a graph as follows.

Referring to Fig. 2, Fig. 2 shows the operating torque curve of the hinge mechanism of a notebook computer, wherein the hinge mechanism does not have the function of locking the positioning screen, and the screen is fixed on the base by a latch mechanism (not shown) , the latch mechanism needs to be released before the screen can be opened during operation. It can be seen from Fig. 2 that in the process of opening the screen 12 (θ=0°～180°), the required operating torque T is a fixed value A ₁ , and in the process of closing the screen 12 (θ=180°～0°) , the required operating torque T is a fixed value A, where A ₁ =0.7A～0.75A.

Referring to Fig. 3, Fig. 3 shows the operating torque curve of the hinge mechanism of another notebook computer. This kind of hinge mechanism provides the function of locking and positioning when the screen is closed, that is, there is no need to use a latch mechanism when closing the screen. Allows the screen to be fixed to the base. Since this rotating shaft mechanism provides the function of locking and positioning when the screen is closed, there is still an operating torque when the closing angle is zero (θ=0°). It can be seen from Fig. 3 that in most of the operation process (when the angle is between 15°-180° and 180°-15°), the required operating torque T is fixed value _A1 and fixed value A respectively. In addition, A ₀ =1.2A in FIG. 3 .

Since the designs of the rotating shaft mechanisms of different manufacturers are not the same, but the operating torque is similar, the above only uses the torque curve diagram for illustration, and does not describe the actual structure of the rotating shaft mechanism in detail.

For the appearance factor of the current notebook computer, the battery is arranged on the second half of the base near the shaft mechanism, because the battery is a heavier accessory of the notebook computer, this design will cause the weight to be distributed on the second half of the base, so in While opening the screen, the base is easily lifted. When the screen is opened to a certain angle, the base will suddenly fall down due to its own weight and hit the table, or the base will continue to lift up with the screen, so that the screen cannot be opened smoothly. At this time, another Use only one hand to complete the operation.

new content

The purpose of the present invention is to solve the above-mentioned problems and provide a notebook computer with a rotating shaft mechanism that opens light and closes heavy, and its operating torque will change due to different rotation angles.

The novel notebook computer includes a screen, a base, and a rotating shaft mechanism. Wherein, the rotating shaft mechanism includes a shaft sleeve, a rotating shaft, a follower and a resistance structure. The shaft sleeve is fixed on the base. The rotating shaft is fixed on the screen and is rotatably arranged in the shaft sleeve. The follower is connected to the rotating shaft and driven by the rotating shaft. The resistance member is arranged beside the follower. When the rotating shaft rotates within the first angle range, the follower does not contact the resistance member. When the rotating shaft rotates within the second angle range, the follower contacts the resistance member and receives resistance.

Since the resistance in different angle ranges is not the same, the operating torque required by the shaft mechanism will also change due to the different rotation angles, so that the user can easily open and close the screen with one hand, and it can prevent the base from hitting the desktop The invention solves the problems of laborious operation, inconvenience and possible damage of the conventional notebook computer.

In order to make the above-mentioned purposes, features, and advantages of the present invention more obvious and easy to understand, preferred embodiments are specifically cited below and described in detail with accompanying drawings.

Detailed ways

In order to open and close the screen smoothly, the operating torque of the novel rotating shaft mechanism will be changed according to the opening and closing angles of the screen. The operation of the new type of rotating shaft mechanism is firstly described below using the torque curve, and then the actual structure of the new type of rotating shaft mechanism is introduced.

Referring to FIG. 4 , FIG. 4 shows an operating torque curve of a rotating shaft mechanism of the present invention, wherein the rotating shaft mechanism does not have the function of locking the positioning screen. It can be seen from Fig. 4 that the operating torque T is a fixed value A ₁ when the screen opening angle is between 0° and 120°, and the screen can be opened with a relatively small force at this time. But when the opening angle of the screen is 120°～180°, the required operating torque will increase from A ₁ to A, that is, a larger force is required to continue opening the screen, so it can prevent the screen from being damaged due to its own The weight automatically moves in the direction of opening. When the closing angle of the screen is 180°～120°, the operating torque is also A to prevent the screen from moving in the opening direction due to its own weight. When the closing angle of the screen is 120°～0°, the required operating torque will be Reducing from A to A ₂ , where A ₂ =0.9A, can turn off the screen with less force. It should be noted that the operating torque A ₂ (=0.9A) required to close the screen is greater than the operating torque A ₁ (=0.7A-0.75A) required to open the screen. In other words, closing the screen is more laborious than opening the screen. When the closing angle of the screen is between 60° and 0°, it prevents the screen from automatically moving towards the closing direction due to its own weight.

Referring to Fig. 5, Fig. 5 shows the operating torque curve diagram of another rotating shaft mechanism of the present invention. This rotating shaft mechanism provides the function of locking and positioning when the screen is closed, so when the closing angle is zero (θ=0°) There is still operating torque. It can be seen from Fig. 5 that the required operating torque T changes when the angle is 120°, which is similar to that of Fig. 4 above, so its description is omitted.

Referring to FIG. 6 and FIG. 7 at the same time, FIG. 6 is an assembled view of the first embodiment of the rotating shaft mechanism according to the present invention, and FIG. 7 is an exploded view of the rotating shaft mechanism in FIG. 6 . Wherein, the shaft sleeve 11 is fixedly connected to the base (not shown) of the notebook computer via a connecting piece 17, and the rotating shaft 12 is fixedly connected to the screen (not shown) of the notebook computer via another connecting piece 18, When the screen rotates relative to the base, the rotating shaft 12 will be driven by the screen to rotate in the sleeve 11 .

The follower 14 has a flange 142 and a through hole 141 through which the rotating shaft 12 passes. The cross section of the rotating shaft 12 is non-circular, and the shape of the through hole 141 matches the cross section of the rotating shaft 12 so that the rotating shaft 12 can drive the driven member 14 to rotate.

The rotating shaft 12 passes through the sleeve 11 , the follower 14 , a plurality of spacers 15 , and the stopper 16 sequentially. Wherein, the stopper 16 is fixed on the rotating shaft 12 , so that the follower 14 and the washer 15 are sandwiched between the shaft sleeve 11 and the stopper 16 .

A resistance member 13 protrudes from the end surface of the shaft sleeve 11 and is arranged beside the follower 14 . When the rotating shaft 12 rotates within the first angle range (for example, 0°-120°), the follower 14 rotates with the rotating shaft 12 but does not contact the resistance member 13 , and the required operating torque is relatively small. And when the rotating shaft 12 rotates in the second angle range (for example, 120°～180°), the follower 14 will contact the resistance member 13 and be resisted, and the required operating torque will increase at this time, as shown in Fig. 4 and Fig. 5, the operating torque increases from _A1 to A.

Referring to FIG. 8 , FIG. 8 is an assembled view of the second embodiment of the rotating shaft mechanism according to the present invention. Wherein, the shaft sleeve 21 is fixedly connected to the base (not shown) of the notebook computer via a connecting piece 27, and the rotating shaft 22 is fixedly connected to the screen (not shown) of the notebook computer via another connecting piece 26, When the screen rotates relative to the base, the rotating shaft 22 will be driven by the screen to rotate in the sleeve 21 .

Referring to FIG. 9 , the follower 24 has a flange 242 and a through hole 241 , and the rotating shaft 22 passes through the through hole 241 . The cross section of the rotating shaft 22 is non-circular, and the shape of the through hole 241 matches the cross section of the rotating shaft 22 so that the rotating shaft 22 can drive the driven member 24 to rotate.

Referring to FIG. 8 again, the resistance member 23 is disposed beside the follower 24 . In this embodiment, the resistance member 23 is a torsion spring, and one end of the torsion spring is fixed on the connecting member 27 . When the rotating shaft 22 rotates within the first angle range (for example, 0°-120°), the follower 24 rotates with the rotating shaft 22 but does not contact the resistance member 23, and the required operating torque is relatively small. And when the rotating shaft 22 rotates in the second angle range (for example, 120 ° ~ 180 °), the follower 24 will contact the resistance member 23 and receive resistance, and the required operating torque increases at this time, as shown in Figure 4 and Figure 5 As shown, the operating torque increases from _A1 to A.

To sum up, the operating torque required by the new type of rotating shaft mechanism will change due to the different rotation angles, and the operating torque required in the opening direction is smaller than that in the closing direction, so that the user can easily use a single The screen can be opened and closed by hand, and the base can be prevented from colliding with the desktop, thereby solving the problems of laborious operation, inconvenience and possible damage of the conventional notebook computer.
