Fig. 2A is a schematic side sectional view of the notebook computer in Fig. 1A along the line A-A. FIG. 2B is a partially enlarged schematic diagram of the notebook computer of FIG. 2A. FIG. 2C is an enlarged cross-sectional view of the notebook computer in FIG. 2A when it is expanded 90 degrees. 2D is an enlarged schematic cross-sectional view of the notebook computer in FIG. 2A in a closed state.

1A, 2A and 2B, when the first body 110 and the second body 120 are expanded to a first angle A1 (approximately 140 degrees shown in the figure), the steering portion 121 drives the linkage structure 140 to push against The heat dissipation module 130 makes the upper cover 111 rotate in a first rotation direction T1 and is relatively far away from the lower cover 112, and can form two air outlets AO on opposite sides of the first body 110 and expose at least a part of the heat dissipation module 130 , The two air outlets AO can be used as waste heat exhaust paths and thereby improve the heat dissipation efficiency of the heat dissipation module 130.

Furthermore, when the first body 110 and the second body 120 are expanded to a first angle A1, an included angle CA exists between the upper cover 111 and the lower cover 112. A gap S gradually increasing toward the linkage structure 140 is formed between the heat dissipation module 130 and the lower cover 112, and there is a gap G between the turning portion 121 and the lower cover 112. It is explained here that one end of the upper cover 111 and the turning portion 121 both protrude below the lower cover 112 as supporting members in the unfolded state (the first unfolded angle A1). After the lower cover 112 is lifted, the ventilation efficiency of the multiple ventilation openings AI can be improved. Therefore, in the above-mentioned unfolded state (the first unfolded angle A1), the notebook computer 100 is suitable for the working mode.

2C and 2D, when the first body 110 and the second body 120 are closed to each other (see FIG. 2C) or expanded to a second angle A2 (see FIG. 2D, for example, 90 degrees) that is less than the first angle A1 , The upper cover 111 and the lower cover 112 abut against each other to shield the heat dissipation module 130, the above-mentioned closed state and the expanded state (expanded at the second angle A2), the upper cover 111 and the lower cover 112 are in a flush state with each other, and have a small volume Characteristics. Therefore, the notebook computer 100 is suitable for carrying (closed and closed state) or entertainment mode (expanding the second angle A2).

2A to 2D, in detail, the steering portion 121 has a rotating space RS, a rotating curved surface CS, and a pushing plane FS. The linkage structure 140 is disposed in the rotation space RS and has a pivot portion 141 and a plurality of top support portions 142. The pivot portion 141 is rotatably disposed in the rotation space RS and contacts the rotation curved surface CS. A plurality of top bracing portions 142 are formed on the pivoting portion 141 and protrude outside the rotating space RS. The pushing plane FS is located on the plurality of top support parts 142. The heat dissipation module 130 has an accommodation slot AG suitable for receiving the plurality of top support portions 142 of the linkage structure 140.

2A and 2B, when the first body 110 and the second body 120 expand to a first angle A1, the steering portion 121 rotates in a second rotation direction T2 opposite to the first rotation direction T1, so as to turn the curved surface The CS slides along the pivoting portion 141 and the pushing plane FS pushes against the two top support portions 142. The linkage structure 140 rotates in the second rotation direction T2 relative to the steering portion 121 and pushes the heat dissipation module 130 upward through the plurality of top bracing portions 142, and simultaneously pushes the upper cover 111 to pivot relative to the lower cover 112 to form two air outlets AO.

2A and 2C, when the first body 110 and the second body 120 are mutually expanded to a second angle A2 that is smaller than the first angle A1, the steering portion 121 faces the second rotation direction T2 opposite to the first rotation direction T1 Rotate so that the rotating curved surface CS slides along the pivot portion 141 and pushes the plane FS to approach and contact the two top support portions 142. In this state, the pushing plane FS does not push the two top support parts 142, so the two top support parts 142 are still received in the pocket AG of the heat dissipation module 130, and the upper cover 111 and the lower cover 112 are still flush with each other The heat dissipation module 130 is wrapped in the heat dissipation space HS.

2A and 2D, when the first body 110 and the second body 120 are closed to each other, that is, the first body 110 and the second body 120 are stacked parallel to each other. The steering portion 121 rotates in the first rotation direction T1 so that the rotating curved surface CS slides along the pivot portion 141 and pushes the plane FS away from the plurality of top support portions 142. In this state, the pushing plane FS is far away from the two top support parts 142 and the two top support parts 142 are received in the groove AG of the heat dissipation module 130. The upper cover 111 and the lower cover 112 are flush with each other to cover the heat dissipation module 130 In the heat dissipation space HS.

Briefly, with reference to FIG. 2D and FIG. 2C, the second body 120 relative to the first body 110 to expand from 0 degrees 90 degrees of the process, linkage structure 140 remains still because of heat dissipation module 130 is pressed against the interlocking structure 140 The upper cover 111 and the lower cover 112 of the first body 110 are on the top support portions 142 and abut against each other. In the steering path from 0 degrees to 90 degrees, the steering portion 121 of the second body 120 and the pivoting portion 141 of the linkage structure 140 slide relatively.

2C and 2B, when the second body 120 is expanded from 90 degrees to 140 degrees relative to the first body 110, the linkage structure 140 is driven by the steering portion 121 of the second body 120 and passes through the plurality of top support portions 142 Lift up the heat dissipation module 130 that is only pressed on it. Because the heat dissipation module 130 is lifted by the plurality of top bracing portions 142, the upper cover 111 rotates relative to the lower cover 112 with the two rotating shafts 1111 as fulcrums to form an included angle CA, so that the formation between the heat dissipation module 130 and the lower cover 112 helps For heat dissipation gap S. In the steering path from 90 degrees to 140 degrees, the steering portion 121 of the second body 120 and the pivoting portion 141 of the linkage structure 140 pivot synchronously.

1B and 2A, the notebook computer 100 includes a plurality of support bars 150, respectively disposed on the bottom surface of the upper cover 111 and the lower cover 112 of the first body 110 to support the first body 110, which can avoid the upper cover 111 and the lower cover 112 directly touches the plane to cause surface damage. In addition, each stay 150 is made of non-slip material, which has a non-slip effect.

3A to 3D are action diagrams of the rotation process of the second body and the linkage mechanism of the notebook computer of FIG. 2A.

2D, 2E, and FIGS. 3A to 3C, when the second body 120 rotates from 0 to 90 degrees relative to the first body 110, the linkage structure 140 remains stationary due to the lower pressure limit of the heat dissipation module 130 . In detail, during the rotation from 0 degrees to 90 degrees, the second body 120 turns relative to the linkage structure 140, the turning curved surface CS of the steering portion 121 slides along the pivot portion 141, and the pushing plane FS of the steering portion 121 finally abuts Lean against the corresponding top brace 142. Therefore, the second body 120 and the linkage structure 140 move relative to each other during the rotation from 0 degrees to 90 degrees.

2B, 3D and 3E, when the second body 120 rotates from 90 degrees to 140 degrees relative to the first body 110, the top support portion 142 of the linkage structure 140 is pushed by the pushing plane FS of the steering portion 121, and Lift the heat dissipation module 130. In detail, during the rotation from 90 degrees to 140 degrees, since the pushing plane FS of the steering portion 121 and the top support portion 142 of the linkage structure 140 abut against each other, when the second body 120 turns, the linkage structure is driven synchronously 140 rotates relative to the lower cover 112 of the first body 110. Therefore, the second body 120 and the linkage structure 140 move synchronously during the rotation from 90 degrees to 140 degrees.

In summary, the notebook computer of the present invention has a first body and a second body that can be relatively expanded and closed. When the first body and the second body are expanded to a first angle, they can be pushed against by the linkage structure. The heat dissipation module makes the upper cover of the first body relatively far away from the lower cover, and two air outlets are formed on both sides of the first body, which is beneficial to improve the heat dissipation efficiency of the heat dissipation module. Furthermore, when the first body and the second body are closed to each other, the upper cover of the first body abuts against the lower cover to reduce the volume of the whole machine. Therefore, the notebook computer of the present invention has the characteristics of light and thin volume and high heat dissipation efficiency.

Furthermore, in the notebook computer of this case, during the unfolding process of the first body and the second body, the upper cover and the lower cover are opened synchronously through the linkage structure to form two air outlets exposing the heat dissipation module, thereby enhancing the notebook computer The heat dissipation efficiency. During the closing process of the first body and the second body, the upper cover and the lower cover abut against each other through gravity and rotating external force, so that the two air outlets disappear and cover the heat dissipation module, thereby reducing the volume of the first body.
