Description

Electronic device

The present invention relates to an electronic device, and particularly to an electronic device including a main display and an auxiliary display.

Due to its multi-tasking, high computing performance, and easy portability, notebook computers have become an indispensable tool for modern people. Generally speaking, a notebook computer includes a host and a display, wherein the display is pivotally connected to the host, and the host is integrated with a keyboard.

In order to improve the flexibility of the user's operation, a notebook computer that integrates an auxiliary display on the host has been proposed. In detail, the auxiliary display and the keyboard are located on the same working plane, and the auxiliary display and the keyboard are arranged side by side. Because the angle and height of the auxiliary display cannot be adjusted in most cases, it is relatively inconvenient for the user to operate, and the eyes are prone to fatigue.

This new creation provides an electronic device with excellent operating convenience.

This new creation proposes an electronic device, which includes a host, a hinge mechanism, a main display, an auxiliary display, and a lifting mechanism. The hinge mechanism includes a bracket, a rotating shaft, a first gear, a second gear, and a third gear. The bracket is fixed to the host, and the rotating shaft, the first gear, the second gear, and the third gear are pivoted on the bracket. The first gear is fixed on the rotating shaft, wherein the first gear is meshed with the second gear, and the second gear is meshed with the third gear. The main display is pivotally connected to the bracket through the hinge. The auxiliary display includes a lifting end close to the hinge mechanism and a sliding end away from the hinge mechanism, and the sliding end is slidably connected to the host. The lifting mechanism includes a cam and a crank pivoted on the bracket. The cam is mechanically coupled to the third gear to rotate synchronously with the third gear. The cam contacts the crank, and the lifting end is pivotally connected to the crank.

Based on the above, the electronic device created by the present invention is integrated with an auxiliary display, in which the angle and height of the auxiliary display are adjustable to facilitate the user to operate the auxiliary display and improve the user's comfort when viewing the auxiliary display. Furthermore, the lifting of the auxiliary display is linked with the turning of the main display. When the main display is turned relative to the host and expanded to a predetermined angle, the auxiliary display is raised to the maximum lifting angle and height. If the main display continues to flip to a larger unfolding angle, the auxiliary display will drop from the maximum elevation angle and height to provide users with different operation and viewing modes.

In order to make the above-mentioned features and advantages of the new creation more obvious and understandable, the following embodiments are specially cited, and the accompanying drawings are described in detail as follows.

On the other hand, the cam 151 contacts the crank 152, and the lifting end 131 is pivotally connected to the crank 152. When the cam 151 contacts the crank 152 through different sections, the crank 152 rotates relative to the bracket 141, and the lifting end 131 is lifted or lowered by the crank 152, as shown in FIGS. 4A, 5A and 6A.

4A and 4C, in this embodiment, the crank 152 includes a driven portion 152a, a pivoting portion 152b, and a lifting portion 152c, wherein the pivoting portion 152b is pivoted on the bracket 141, and is located at the driven portion 152a and the lifting部152c between. In detail, the cam 151 contacts the driven portion 152a, and the lifting end 131 is pivotally connected to the lifting portion 152c. As the cam 151 contacts the driven portion 152a through different sections, the crank 152 rotates to different degrees, and the auxiliary display 130 is driven by the rising or falling of the lifting portion 152c, as shown in FIGS. 4A, 5A, and 6A.

Fig. 4D is an enlarged schematic view of the cam of Fig. 4A. As shown in FIGS. 4A and 4D, the cam 151 has a delay section 151a, a driving section 151b, and a slow-down section 151c, and the driving section 151b is located between the delay section 151a and the slow-down section 151c. In the state shown in FIG. 4A, the retarded section 151a of the cam 151 contacts the driven portion 152a, and since the driven portion 152a is not further pressed down, the crank 152 remains stationary.

As shown in Figs. 4D and 5A, when the cam 151 rotates relative to the bracket 141 and contacts the driven portion 152a through the driving section 151b, the driven portion 152a is further pressed down, and the crank 152 is opposite to the crank 152 along the first rotation direction D1 The bracket 141 rotates to lift the lifting end 131 through the lifting portion 152c. In addition, the sliding end 132 slides and rotates relative to the host 110, as shown in FIG. 5B.

As shown in FIGS. 4D and 6A, when the cam 151 continues to rotate relative to the bracket 141 and contacts the driven portion 152a through the slow-down section 151c, the degree of depression of the driven portion 152a gradually decreases, and the crank 152 moves in the reverse direction. The second rotation direction D2 in the first rotation direction D1 rotates relative to the bracket 141 to drive the lifting end 131 to descend through the lifting portion 152c. In addition, the sliding end 132 slides and rotates relative to the host 110, as shown in FIG. 6B. Finally, the auxiliary display 130 returns to the initial position, that is, the position before being raised.

As shown in FIGS. 4A and 4D, in this embodiment, the cam 151 further has a rotation axis 151d, and the distance between the delay section 151a and the rotation axis 151d is a first distance S1. The driving section 151b is connected to the delay section 151a, wherein the distance between the driving section 151b and the rotation axis 151d gradually increases from the second distance S2 to the third distance S3, and the second distance S2 is greater than the first distance S1. On the other hand, the descending section 151c is connected to the driving section 151b, wherein the distance between the descending section 151c and the rotation axis 151d gradually decreases from the third distance S3 to the fourth distance S4, and the fourth distance S4 is equal to the first distance S1.

As shown in FIGS. 1, 4A and 4D, the shortest distance between any one of the delay sections 151a used to contact the end point of the driven portion 152a and the rotation axis 151d at different timings is the first distance S1. Therefore, no matter the delay section 151a contacts the rotation axis 151d through any end point, the driven portion 152a is not further pressed down, and the crank 152 does not rotate. Furthermore, when the main display 120 is flipped relative to the host 110 and the expansion angle is not greater than a specific angle (for example, 10 degrees), the cam 151 rotates relative to the driven portion 152a, and the delay section 151a contacts the driven portion 152a, so the lifting portion 152c and the auxiliary display 130 remain in the initial position without being raised.

As shown in FIGS. 2, 4D, and 5A, the shortest distance between the end point of the driven portion 152a and the rotation axis 151d on the driving section 151b at different timings is from the boundary between the delay section 151a and the driving section 151b It gradually increases to the boundary between the driving section 151b and the slow-down section 151c, that is, gradually increases from the second distance S2 to the third distance S3. When the cam 151 rotates relative to the driven portion 152a and the driving section 151b contacts the driven portion 152a, the crank 152 rotates relative to the bracket 141 along the first rotation direction D1, and the lifting portion 152c lifts the lifting end 131. Furthermore, when the driving section 151b contacts the driven section 152a through the end point of the boundary between the delay section 151a and the driving section 151b, the more the driven section 152a is pressed down, and the lifting section 152c and the lifting end 131 The lifting height is also higher. Once the shortest distance between the end point of the driving section 151b contacting the driven part 152a and the rotation axis 151d is the third distance S3, the lifting part 152c and the lifting end 131 are at the maximum lifting height.

As shown in FIGS. 3, 4D, and 6A, any one of the descending sections 151c is used to contact the end point of the driven portion 152a and the rotation axis 151d at different timings to move away from the driving section 151b and the descending section. The direction of the junction of 151c gradually decreases, that is, it gradually decreases from the third distance S3 to the fourth distance S4. When the cam 151 rotates relative to the driven portion 152a and the slow-down section 151c contacts the driven portion 152a, the crank 152 rotates relative to the bracket 141 along the second rotation direction D2, and the lifting portion 152c drives the lifting end 131 to descend. More specifically, when the descending section 151c contacts the driven portion 152a through the end of the boundary between the driving section 151b and the descending section 151c, the lower the driven portion 152a is pressed down. Once the shortest distance between the end point of the descending section 151c contacting the driven part 152a and the rotation axis 151d is the fourth distance S4, the lifting part 152c and the auxiliary display 130 move back to the initial position.

That is, as the cam 151 contacts the driven portion 152a through different sections, the crank 152 rotates to different degrees, so that the lifting portion 152c rises or falls.

As shown in FIG. 4C, the lifting mechanism 150 further includes a shaft 153 and a torsion spring 154. The pivot portion 152b of the crank 152 is fixed with the shaft 153, and the shaft 153 is pivoted to the bracket 141, so the crank 152 can pass through the shaft 153 rotates relative to the bracket 141. On the other hand, the torsion spring 154 is sleeved on the shaft 153, wherein one end of the torsion spring 154 is fixed to the bracket 141, and the other end of the torsion spring 154 is fixed to the crank 152. The torsion spring 154 is configured to provide the elastic force required for the reset of the crank 152 to drive the auxiliary display 130 to return from the third mode shown in FIG. 3 to the first mode shown in FIG. 1.

As shown in FIGS. 4B, 5B, and 6B, the electronic device 100 further includes a rotating bracket 160 and a sliding rail 170 fixed to the rotating bracket 160, wherein the rotating bracket 160 is pivoted to the host 110, and the sliding end 132 has a sliding groove 132a . In detail, the sliding rail 170 is slidably connected to the sliding groove 132 a, so the auxiliary display 130 can slide relative to the sliding rail 170 and rotate relative to the host 110 through the sliding rail 170 and the rotating bracket 160.

As shown in FIGS. 1, 4A, and 4B, the rotating bracket 160 and the lifting mechanism 150 are respectively disposed on two opposite sides of the auxiliary display 130, and serve as the rotating fulcrum of the auxiliary display 130. On the other hand, the electronic device 100 further includes The keyboard 180 of the display 130 and the sliding end 132 are located between the lifting end 131 and the keyboard 180.

In summary, the electronic device created by the present invention is integrated with an auxiliary display, in which the angle and height of the auxiliary display are adjustable, so that the user can operate the auxiliary display and improve the comfort of the user viewing the auxiliary display. Furthermore, the lifting of the auxiliary display is linked with the turning of the main display. When the main display is turned relative to the host and expanded to a preset angle, the auxiliary display is raised to the maximum lifting angle and height. If the main display continues to flip to a larger deployment angle, the auxiliary display will drop from the maximum elevation angle and height. When the expansion angle of the main display relative to the host is 180 degrees, the auxiliary display moves back to the initial position, so that the auxiliary display and the main display are substantially coplanar to provide different operation and viewing modes.
