Description

Technical Field

[0001] This invention relates to an electronic device, and more particularly to an electronic device having multiple components. Background Technology

[0002] Generally speaking, electronic devices (such as laptops) are designed with air inlets and air outlets in order to dissipate heat. The air inlets are usually located below the motherboard of the electronic device, while the air outlets are usually located on the rear side of the motherboard away from the user, so that the heat dissipation airflow is exhausted in the direction away from the user.

[0003] However, the placement of these air inlets and outlets is easily obstructed when users place electronic devices on soft surfaces such as laps, sofas, or beds. This prevents effective heat dissipation, causing the device's temperature to rise and affecting user comfort and the device's performance. Therefore, how to ensure that the air inlets and outlets of electronic devices are not obstructed under any circumstances to allow for effective heat dissipation is a worthy area of ​​research in this field. Summary of the Invention

[0004] This invention relates to an electronic device with good heat dissipation efficiency.

[0005] According to an embodiment of the present invention, an electronic device includes a first body, a second body, and a pivot structure. The first body includes a first portion and a second portion pivotally connected to each other, the first portion having a groove. The pivot structure is pivotally connected between an edge of the second body and the second portion. When the second body is unfolded relative to the first body from a closed state to a first unfolded state, the pivot structure pushes against the first portion to cause the first portion to rotate relative to the second portion. When the second body continues to unfold relative to the first body from the first unfolded state to a second unfolded state, the edge of the second body pushes against the first portion to cause the first portion to continue to rotate relative to the second portion. When the second body is in a closed state, the pivot structure is at least partially received within the groove.

[0006] In an embodiment of the present invention, the first body includes a motherboard disposed within a first portion.

[0007] In an embodiment of the invention, the first body includes a battery disposed within a second portion.

[0008] In an embodiment of the invention, the second part includes a seat portion and an extension portion, the first part is pivotally connected to the seat portion, a first section of the extension portion is connected to the top end of the seat portion, a second section of the extension portion extends from the first section and is located above the first part, and a pivot structure is pivotally connected to the second section and is at least partially located between the second section and the first part.

[0009] In an embodiment of the invention, the extension is a keyboard assembly.

[0010] In an embodiment of the invention, there is a gap between the first part and the second part, through which the heat dissipation airflow is adapted to enter the first part. When the second body unfolds from the closed state to the first unfolded state, the gap widens, and when the second body continues to unfold from the first unfolded state to the second unfolded state, the gap widens even more.

[0011] In an embodiment of the invention, the gap is located between the top surface of the first part and the second part, the top surface of the first part has an air inlet, and the top surface or the rear side surface of the first part has an air outlet.

[0012] In an embodiment of the present invention, the first body includes a fan disposed within a first portion and adapted to generate a cooling airflow. When the second body is in a closed state, the fan has a first rotational speed. When the second body is in a first unfolded state, the fan has a second rotational speed greater than the first rotational speed. When the second body is in a second unfolded state, the fan has a third rotational speed greater than the second rotational speed.

[0013] In an embodiment of the present invention, the first body includes an elastic element connected between the first part and the second part. When the second body is unfolded relative to the first body, the first part rotates relative to the second part against the elastic force of the elastic element, and when the second body is in a closed state, the first part is reset by the elastic force of the elastic element.

[0014] In an embodiment of the invention, when viewed along a direction parallel to the axial direction of the pivot structure, the pivot structure has a polygonal profile.

[0015] In an embodiment of the invention, the pivot structure includes a circular structure and a polygonal structure, with the polygonal structure connected to the circular structure.

[0016] In an embodiment of the present invention, the polygonal structure has a first side, one end of which is connected to a circular structure, and the line connecting the other end of the first side and the center of the circular structure has a first angle with the first side.

[0017] In an embodiment of the invention, the first included angle is between 15 degrees and 30 degrees.

[0018] In an embodiment of the invention, when the electronic device is in a first state, the pivot structure does not contact the groove, and the first state is a closed state.

[0019] In an embodiment of the invention, the polygonal structure has a second side, one end of which is connected to the other end of the first side, and the line connecting the other end of the second side and the center of the circular structure forms a second angle with the second side.

[0020] In an embodiment of the invention, the range of the second included angle is between 45 degrees and 55 degrees.

[0021] In an embodiment of the invention, when the electronic device is in the second state, the other end of the first side and one end of the second side are in contact with the groove.

[0022] In an embodiment of the invention, the polygonal structure has a third side, one end of which is connected to the other end of the second side, and the line connecting the other end of the third side and the center of the circular structure forms a third angle with the third side.

[0023] In an embodiment of the invention, the third included angle is between 85 degrees and 95 degrees.

[0024] In an embodiment of the invention, when the electronic device is in the third state, the other end of the second side and one end of the third side are in contact with the groove.

[0025] In an embodiment of the invention, when the electronic device is in the fourth state, the other end of the third side contacts the first part.

[0026] Based on the above, the electronic device of the present invention pushes against the first part via a pivot structure, causing the first part to rotate relative to the second part, thus unfolding the electronic device to a first unfolded state. Furthermore, the electronic device further pushes against the first part via the edge of the second body, causing the first part to continue rotating relative to the second part, and the electronic device then unfolds to a second unfolded state. In this way, the gap between the first and second parts gradually increases as the electronic device unfolds, allowing heat dissipation airflow to enter the interior of the electronic device through the gap. This enables the electronic device to effectively dissipate heat in any state, maintaining user comfort and the processing performance of the electronic device. Attached Figure Description

[0037] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0038] Figure 1 This is a perspective view of an electronic device according to an embodiment of the present invention. Figure 2 yes Figure 1 A perspective view of some components of the electronic device from another angle. Please refer to... Figure 1 and Figure 2 The electronic device 100 of this embodiment includes a first body 110, a second body 120, and a pivot structure 130. The first body 110 includes a first portion 111 and a second portion 112 that are pivotally connected to each other, and the pivot structure 130 is pivotally connected between the edge 121 of the second body 120 and the second portion 112.

[0039] Figures 3A to 3D yes Figure 1 Side views of various operating states of the electronic device. Please refer to... Figures 2 to 3D When the second unit 120 is relative to the first unit 110 from Figure 3A The closed state shown unfolds to Figure 3B In the first deployed state, the pivot structure 130 pushes against the first part 111 to cause the first part 111 to rotate relative to the second part 112. When the second body 120 is positioned relative to the first body 110 from... Figure 3C The first unfolded state shown unfolds to Figure 3DIn the second deployed state shown, the edge 121 of the second body 120 pushes against the first part 111 to cause the first part 111 to continue rotating relative to the second part 112, until the second body 120 is deployed relative to the first body 110 to... Figure 3D The more expanded state is shown.

[0040] In this way, the gap S between the first part 111 and the second part 112 gradually increases as the electronic device 100 unfolds from the closed state to the second unfolded state, allowing the heat dissipation airflow to enter the interior of the electronic device 100 from the outside through the gap S, so that the electronic device 100 can effectively dissipate heat in any state, so as to maintain the user's comfort and the processing efficiency of the electronic device 100.

[0041] In detail, the second part 112 of this embodiment includes a seat portion 1121 and an extension portion 1122. The extension portion 1122 includes a first segment 1122A and a second segment 1122B. The first part 111 is pivotally connected to the seat portion 1121. The first segment 1122A of the extension portion 1122 is connected to the top end of the seat portion 1121. The second segment 1122B of the extension portion 1122 extends from the first segment 1122A and is located above the first part 111. The pivot structure 130 is pivotally connected to the second segment 1122B about the rotation axis A and is at least partially located between the second segment 1122B and the first part 111.

[0042] In this embodiment, the gap S is located between the top surface 1111 of the first part 111 and the second section 1122B of the second part 112. The heat dissipation airflow is adapted to enter the first part 111 through the gap S. The top surface 1111 of the first part 111 has an air inlet B1, and the top surface 1111 or the rear side surface 1112 of the first part 111 has an air outlet B2. When the second body 120 is unfolded from the closed state to the first unfolded state, the gap S widens, and when the second body 120 continues to unfold from the first unfolded state to the second unfolded state, the gap S widens even more.

[0043] Furthermore, the first body 110 of this embodiment includes a fan 113, disposed within the first portion 111 and adapted to generate cooling airflow. When the second body 120... Figure 3A The fan 113 has a first rotational speed when the second unit 120 is in the closed state. Figure 3B and 3C As shown in the first deployed state, fan 113 has a second rotational speed greater than the first rotational speed. When the second body 120 is in... Figure 3DAs shown in the second deployed state, fan 113 has a third rotational speed greater than the second rotational speed. The airflow velocity is affected by the different rotational speeds of fan 113. When the second housing 120 is in the second deployed state, the gap S has its maximum value and the third rotational speed of fan 113 is also its maximum speed. The airflow can flow more efficiently into the air inlet B1 of the first part 111, cooling the electronic components inside the first part 111 before flowing out through the air outlet B2, thus maintaining the processing performance of the electronic device 100 during user operation. Conversely, when the second housing 120 is in the closed state, although the gap S is at its minimum value and the first rotational speed of fan is also at its minimum speed, the airflow can still flow into the air inlet B1 of the first part 111, cooling the electronic components inside the first part 111 before flowing out through the air outlet B2, allowing the second housing 120 to effectively dissipate heat in any state.

[0044] Figures 4A to 4D They are respectively Figures 3A to 3D A partially enlarged view of the electronic device. Please refer to... Figures 4A to 4D In this embodiment of the electronic device 100, when viewed along an axial direction parallel to the rotation axis A of the pivot structure 130, the pivot structure 130 has a polygonal profile eccentric to its rotation axis A. The first portion 111 has a groove 1113. When the second body 120 is... Figure 4A In the closed state shown, the pivot structure 130 is at least partially accommodated within the groove 1113. When the second body 120 is deployed relative to the first body 110... Figure 4B In the first deployed state, as shown, the polygonal outline of the pivot structure 130 pushes against the groove 1113 of the first part 111, causing the first part 111 to rotate relative to the second part 112. As the second body 120 continues to deploy relative to the first body 110... Figure 4C The second unfolded state shown and Figure 4D In the more extended state shown, the polygonal outline of the pivot structure 130 no longer pushes against the first portion 111, but instead is pushed against the first portion 111 by the edge 121 of the second body 120. In other embodiments, the shape of the pivot structure 130 may be an eccentric outline of other forms, and the present invention is not limited thereto.

[0045] As described above, during the process of the second body 120 unfolding from the closed state to the first unfolded state relative to the first body 110, the pivot structure 130 pushes against the groove 1113 of the first part 111 to drive the second body 120 to pivot relative to the first body 110. Then, during the process of the second body 120 unfolding from the first unfolded state to the second unfolded state relative to the first body 110, the edge 121 pushes against the first part 111 to drive the relative pivot of the second body 120 to the first body 110. That is, the pivot structure 130 does not always push against the groove 1113 of the first part 111 during the entire operation, so it is not necessary to design the outer contour of the pivot structure 130 to be more off-center in order to ensure that the pivot structure 130 can continuously push against the groove 1113 of the first part 111 throughout the entire operation. In this way, the shape of the pivot structure 130 can be effectively reduced, and the outline of the pivot structure 130 can conform to the outer outline of the first part 111 and the second body 120, making the overall appearance of the electronic device 100 more aesthetically pleasing.

[0046] In this embodiment, the first body 110 is as follows: Figures 3A to 3D The device includes a motherboard 114 and a battery 115, which are respectively disposed in the first part 111 and the second part 112. The extension 1122 of the second part 112 is a keyboard assembly. By distributing the motherboard 114 and the battery 115 in the first part 111 and the second part 112 of the first body 110, the battery 115 is less affected by the heat dissipated by the motherboard 114 when the electronic device 100 is in operation. This avoids the problem of the battery 115 overheating and having difficulty dissipating heat, thus allowing the battery 115 to have a longer service life.

[0047] In this embodiment, the first body 110 includes an elastic element 116 connected between the first portion 111 and the second portion 112. When the second body 120 is unfolded relative to the first body 110 to a first unfolded state and a second unfolded state, the first portion 111 rotates relative to the second portion 112 against the elastic force of the elastic element 116. When the second body 120 is in a closed state, the first portion 111 is reset by the elastic force of the elastic element 116. In this embodiment, the elastic element 116 is a torsion spring, but the invention is not limited thereto.

[0048] In this embodiment, when the electronic device 100 such Figure 4A When the location is in the first state P1, the pivot structure 130 is not in contact with the groove 1113. The first state P1 is the same as described above. Figure 4A The closed state is shown.

[0049] Figure 5A and Figure 5B yes Figure 1 A schematic diagram of the pivot structure in the second state. Please refer to... Figure 1 , Figure 5A and Figure 5B The pivot structure 130 of this embodiment includes a circular structure 131 and a polygonal structure 132, with the polygonal structure 132 connected to the circular structure 131. The polygonal structure 132 has a first side 1321, a second side 1322, and a third side 1323. One end 1321A of the first side is connected to the circular structure 131. A first angle Q1 is formed between the line connecting the other end 1321B of the first side and the center O of the circular structure 131, and the first side 1321. The first angle Q1 ranges between 15 degrees and 30 degrees. One end 1322A of the second side is connected to the other end 1321B of the first side. A second angle Q2 is formed between the line connecting the other end 1322B of the second side and the center O of the circular structure 131, and the second side 1322. The second angle Q2 ranges between 45 degrees and 55 degrees. One end 1323A of the third side is connected to the other end 1322B of the second side. The line connecting the other end 1323B of the third side and the center O of the circular structure 131 has a third included angle Q3 with the third side 1323. The range of the third included angle Q3 is between 85 degrees and 95 degrees.

[0050] Following the above, when the electronic device 100 of this embodiment is in the second state P2, such as 5A and 5B, the other end 1321B of the first side and one end 1322A of the second side are in contact with the groove 1113. The second state P2 is the same as the first unfolded state described above.

[0051] Figure 5C and Figure 5D yes Figure 1 A schematic diagram of the pivot structure in the third state. Please refer to... Figure 1 , Figure 5C and Figure 5D When the electronic device 100 of this embodiment is in the third state P3, the other end 1322B of the second side and one end 1323A of the third side are in contact with the groove 1113. The aforementioned second unfolded state includes the third state P3.

[0052] Figure 5E yes Figure 1 A schematic diagram of the pivot structure in the fourth state. Please refer to... Figure 1 , Figure 4D and Figure 5E When the electronic device 100 is in the fourth state P4, the other end 1323B of the third side contacts the first part 111. The aforementioned second unfolded state includes the fourth state P4, which is the same as described above. Figure 4D The second unfolded state is shown in a more expanded form.

[0053] Figure 6A yes Figure 1A top view of the second body and pivot structure of the electronic device. Please refer to... Figure 6A In this embodiment, the second body 120 and the pivot structure 130 are two independent components, with the pivot structure 130 connected to the edge 121 of the second body 120.

[0054] Figure 6B This is a top view of the second body and pivot structure according to another embodiment of the present invention. Figure 6B The second body 120A and pivot structure 130A of the illustrated embodiment are Figure 6A The difference between the second body 120 and the pivot structure 130 in the illustrated embodiment is that... Figure 6B The second body 120A shown and the pivot structure 130A at its edge 121A are integrally formed.

Figure 6C The second body 120B and pivot structure 130B of the illustrated embodiment are Figure 6A The difference between the second body 120 and the pivot structure 130 in the illustrated embodiment is that... Figure 6C The second body 120B and the pivot structure 130B at its edge 121B are partially integrally formed. The pivot structure 130B and the second body 120B are two independent component designs located near the short sides of the two sides of the second body 120B.

[0056] In summary, the electronic device of the present invention uses a pivot structure to push against the first part, causing the first part to rotate relative to the second part, thus unfolding the electronic device to a first unfolded state. Furthermore, the electronic device is further pushed against the first part by the edge of the second body, causing the first part to continue rotating relative to the second part, and the electronic device then unfolds to a second unfolded state. In this way, the gap between the first and second parts gradually increases as the electronic device unfolds, allowing heat dissipation airflow to enter the interior of the electronic device through the gap. This enables the electronic device to effectively dissipate heat in any state, maintaining user comfort and the processing performance of the electronic device.
