The first casing 32 can be an upper casing of the electronic device 30 and can accommodate a liquid crystal display screen. The electronic device 30 further includes a second casing 36 and a second pivot mechanism 38 disposed in one side of the second casing 36 . The second casing 36 can be the lower casing of the electronic device 30 and can be used to accommodate the keyboard mechanism and other host-related electronic components, such as a motherboard and a hard disk. The electronic device 30 also includes a bridging member 40, a first end 401 and a second end 403 of the bridging member 40 are respectively used to be pivotally connected to the first pivot mechanism 34 and the second pivot mechanism 38, so the first casing 32 can pivot relative to the bridge member 40 through the first pivot mechanism 34, and the bridge member 40 can pivot relative to the second housing 36 through the second pivot mechanism 38, so that the first housing 32 can be relatively The electronic device 30 is opened and closed on the second casing 36 . The electronic device 30 may further include a covering member 50 for covering the bridge member 40 so as to protect the inner structure of the bridge member 40 from being damaged. The electronic device 30 may include a cushioning pad 52 disposed on the outside of the cover 50. When the electronic device 30 is placed on a carrying surface 48, the cushioning pad 52 may be used to avoid a gap between the covering 50 and the carrying surface 48. The resulting friction causes wear.

In addition, the bridging member 40 includes a first abutting portion 42, when the first pivot mechanism 34 pivots relative to the first end 401 of the bridging member 40, the first housing 32 rotates relative to the second housing 36 to When a first angle θ ₁ , for example, the first angle θ ₁ can be 67.5 degrees, the first abutting portion 42 will stop against the side of the first housing 32, so as to limit the first housing 32 and the bridging Rotary movement between pieces 40. The bridging member 40 also includes a second abutting portion 44 , when the second end 403 of the bridging member 40 pivots relative to the second pivot mechanism 38 , the first housing 32 is rotated to be larger than the second housing 36 . When the first angle _θ1 is a second angle θ2 _, for example, the second angle _θ2 can be 135 degrees, the second abutting portion 44 will stop at the side of the second housing 36, thereby limiting Rotational movement between the bridging member 40 and the second housing 36 . Wherein, the pivot torque of the first pivot mechanism 34 relative to the first end 401 is smaller than the pivot torque of the second pivot mechanism 38 relative to the second end 403, that is, when the user applies force to rotate the first When the first housing 32 is used, the bridging member 40 will not rotate relative to the second housing 36 until the side of the first housing 32 stops against the first contact portion 42, because the first pivot mechanism 34 cannot be relatively When the first end 401 of the bridge 40 pivots, the second pivot mechanism 38 pivots relative to the second end 403 of the bridge 40 . The values of the first angle _θ1 and the second angle _θ2 are not limited to those shown in the above embodiments, but depend on design requirements.

Furthermore, the bridging piece 40 may also include a curved portion 46, which is connected to the first abutting portion 42 and the second abutting portion 44 and is used to be disposed on a bearing surface 48. For example, the bridging piece 40 may be A U-shaped structural member. When the first housing 32 is rotated until its side abuts against the first abutting portion 42 of the bridging member 40, the curved portion 46 can rotate relative to the supporting surface 48, so as to drive the second end 403 of the bridging member 40 to move relative to the first abutting portion 42 of the bridging member 40. The two pivoting mechanisms 38 pivot so that a gap H is formed between the second housing 36 and the bearing surface 48 . Wherein, the height of the gap H varies with the rotation angle of the bending portion 46 relative to the carrying surface 48 . For example, the gap H is at its maximum value when the side of the second housing 36 abuts against the second abutting portion 44, and at this time a third included angle _θ3 is formed between the second housing 36 and the bearing surface 48. , and the third included angle θ ₃ is substantially preferably less than 5 degrees. The value of the third included angle _θ3 is not limited to that shown in the above embodiments, but depends on design requirements.

The opening process of the electronic device 30 is as follows, please refer to FIG. 2 and FIG. 4 to FIG. 6 . Fig. 4 is a schematic diagram of the electronic device 30 in a preferred embodiment of the present invention when it is closed, Fig. 5 is a schematic diagram of the electronic device 30 in a preferred embodiment of the present invention during the opening process, and Fig. 6 is a schematic diagram of a preferred embodiment of the present invention A schematic diagram of the electronic device 30 at the maximum opening angle. When the user wants to operate the electronic device 30 , the user can pivot the first housing 32 from the position shown in FIG. 4 to the position shown in FIG. 5 along the clockwise direction D1 . Since the torque of the first pivot mechanism 34 relative to the first end 401 is smaller than the torque of the second pivot mechanism 38 relative to the second end 403, that is to say, the torque that drives the second pivot mechanism 38 to pivot is greater than the torque that drives the second pivot mechanism 38 to pivot. The pivoting torque of the first pivot mechanism 34 , so when the user pushes the first casing 32 to pivot relative to the bridge piece 40 , the torque provided by it is not enough to make the connection between the bridge piece 40 and the second casing 36 During rotation, the bottom of the second housing 36 is attached to the bearing surface 48 . As shown in FIG. 5 , when the first housing 32 pivots to the first angle _θ1 relative to the second housing 36 along the clockwise direction D1, the side of the first housing 32 stops against the side of the bridging member 40. The first abutting portion 42 means that the first casing 32 has pivoted to a maximum angle relative to the bridging member 40, and at this time the first angle _θ1 is substantially preferably 67.5 degrees.

Next, when the first housing 32 continues to rotate clockwise D1 from the position shown in FIG. 5 to the position shown in FIG. The user must apply a torque greater than the pivoting torque of the first pivoting mechanism 34 to drive the second pivoting mechanism 38 to pivot, and the first housing 32 will press down on the bridging member 40 so that the curved portion of the bridging member 40 46 rotates relative to the bearing surface 48, so as to drive the second end 403 of the bridge member 40 to pivot relative to the second pivot mechanism 38. At this time, one end of the curved portion 46 will abut against the bearing surface 48 and the second housing 36 Therefore, a gap H is formed between the second shell 36 and the supporting surface 48 , wherein the height of the gap H changes with the rotation angle of the curved portion 46 relative to the second shell 36 . As shown in FIG. 6, when the first housing 32 pivots to the second angle _θ2 relative to the second housing along the clockwise direction D1, the second abutting portion 44 of the bridging member 40 stops against the second housing. The side of the body 36, that is, the bridge member 40 has pivoted to the maximum angle relative to the second housing 36, wherein the second angle θ ₂ can be substantially preferably 135 degrees, and the curved portion 46 connects the second housing The side of the body 36 reaches the maximum height so that a third included angle θ ₃ is formed between the second housing 36 and the bearing surface 48 , wherein the third included angle θ ₃ is preferably substantially less than 5 degrees. Therefore, when the first housing 32 is rotated to the second angle _θ2 relative to the second housing 36 along the clockwise direction D1, the surface of the second housing 36 can slightly raise an inclination angle relative to the user (that is, The third included angle θ ₃ ) is used to improve the user's comfort in operating the keyboard mechanism disposed on the second casing 36 . In addition, when the first housing 32 rotates relative to the second housing 36 , the gap H formed between the second housing 36 and the bearing surface 48 can prevent the bottom of the second housing 36 from being attached to the bearing surface 48 horizontally. Since the gap H can increase the convective space between the bottom of the second housing 36 and the bearing surface 48 , the heat dissipation efficiency of the electronic components inside the second housing 36 can be further improved.

Similar to the above-mentioned action principle, the closing process of the electronic device 30 is as follows, please refer to FIG. 2 and FIG. 7 to FIG. 9. FIG. A schematic diagram of the closing process of the electronic device 30 in a preferred embodiment of the present invention, and FIG. 9 is a schematic diagram of the electronic device 30 in a closed process in a preferred embodiment of the present invention. When the user wants to close the electronic device 30, the user can pivot the first housing 32 from the position shown in FIG. 7 to the position shown in FIG. The torque at the second end 403 is greater than the torque of the first pivot mechanism 34 relative to the first end 401, that is to say, the torque that drives the second pivot mechanism 38 to pivot is greater than the torque that drives the first pivot mechanism 34 to pivot. Therefore, when the first housing 32 pivots relative to the bridge member 40, there will be no rotational movement between the bridge member 40 and the second housing 36, so the angle between the bridge member 40 and the bearing surface 48 is still maintained. In the value of the third included angle θ ₃ . When the first housing 32 pivots to the first angle _θ1 relative to the first end 401 along the counterclockwise direction D2, the side of the first housing 32 stops against the first abutting portion 42 of the bridging member 40, Since the first housing 32 can no longer pivot relative to the bridge member 40, the user must apply a torque greater than that which drives the first pivot mechanism 34 to pivot, so as to drive the second pivot mechanism 38 to pivot, and at the same time, the bending portion 46 can rotate relative to the second housing 36, so as to drive the second end 403 of the bridge member 40 to pivot to the second angle θ ₂ in the counterclockwise direction D2 relative to the second pivot mechanism, which means that the first housing 32 can pivot from the position shown in FIG. 6 (the dotted line position shown in FIG. 8 and FIG. 9 ) to the position shown in FIG. , until the first housing 32 and the second housing 36 are completely closed, the bottom of the second housing 36 is attached to the bearing surface 48 horizontally. Therefore, the electronic device 30 of the present invention is an innovative mechanism design that can automatically adjust the inclination angle between the second housing 36 and the bearing surface 48 according to the angle between the first housing 32 and the second housing 36 .

Compared with the prior art, the electronic device with the two-shaft pivot joint mechanism of the present invention can synchronously adjust the distance between the second housing and the bearing surface as the angle between the first housing and the second housing changes. It can not only adjust the inclination angle of the keyboard mechanism and raise the height of the liquid crystal display screen, so as to improve the user's comfort in operating the electronic device, but also form a gap between the body and the supporting surface, so as to enhance the convection at the bottom of the electronic device effect, and help to increase the heat dissipation efficiency of the electronic device.

The above descriptions are only preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the scope of the claims of the present utility model shall fall within the scope of the present utility model.
