Description

Technical Field

[0001] The present invention relates to an electronic device. Prior Art

[0002] The ventilation openings of current electronic devices (such as laptops) are fixedly arranged. The hot air inside the electronic device dissipates heat through the fixed ventilation openings, and cannot dissipate heat flexibly according to the usage conditions of the electronic device, resulting in poor heat dissipation efficiency of the electronic device. Summary of the Invention

[0003] The present invention provides an electronic device that can improve heat dissipation efficiency.

[0004] The electronic device of the present invention includes a first body, a second body, and a rotating member. The first body includes a heat dissipation channel. The second body is pivotally connected to the first body. The rotating member includes a rotating portion and a stopping portion, and the rotating portion is connected to the first body and the second body. When the rotating member is in a first state, a first opening is formed between the rotating member and the first body, and the first opening communicates with the heat dissipation channel to form a first heat dissipation flow path. When the rotating member is in a second state, the stopping portion is close to the first body, and a second opening is formed between the rotating portion and the first body, and the second opening communicates with the heat dissipation channel to form a second heat dissipation flow path.

[0005] Based on the above, the first body of the electronic device of the present invention can cooperate with the rotating member to form different openings (the first opening or the second opening) in different states. Thereby, the heat dissipation channel of the first body can communicate with different openings, and dissipate heat through different heat dissipation flow paths (the first heat dissipation flow path or the second heat dissipation flow path), so as to change the air outlet position of the electronic device and improve the heat dissipation efficiency of the electronic device.

[0007] FIG. 1 is a side cross-sectional view of an electronic device according to an embodiment of the present invention. FIG. 2 is an exploded view of the electronic device in FIG. 1. FIG. 3 is a side cross-sectional view after the second body in FIG. 1 is rotated. Cartesian coordinates X-Y-Z are provided herein for facilitating the description of components. Please refer to FIGS. 1 to 3 simultaneously. The electronic device 100 includes a first body 110, a second body 120, and a rotating member 130. The first body 110 includes a heat dissipation channel 111. The rotating member 130 includes a rotating portion 131 and a stopping portion 132. The rotating portion 131 is connected to the first body 110 and the second body 120, such that the second body 120 is pivotally connected to the first body 110. The electronic device 100 is, for example, a notebook computer, but is not limited thereto. The rotating member 130 of this embodiment serves as a rotating shaft between the first body 110 and the second body 120.

[0008] The rotation of the second body 120 relative to the first body 110 can drive the rotating member 130, such that the rotating member 130 switches between a first state M1, M1' (FIGS. 1 and 3) and a second state M2, M2' (FIGS. 4 and 5). A first opening OP1 can be formed between the rotating member 130 and the first body 110, or a second opening OP2 can be formed between the rotating portion 131 and the first body 110. According to the usage state of the rotating member 130, the heat dissipation channel 111 communicates with the first opening OP1 or the second opening OP2, thereby forming a first heat dissipation flow path HF1 or a second heat dissipation flow path HF2. Thereby, the electronic device 100 can, through the rotation of the first body 110 and the second body 120, communicate the heat dissipation channel 111 with different openings (the first opening OP1 or the second opening OP2), dissipate heat through different heat dissipation flow paths (the first heat dissipation flow path HF1 or the second heat dissipation flow path HF2), and change the air outlet position of the electronic device 100. The heat energy in the first body 110 can leave the electronic device 100 with the airflow through the heat dissipation channel 111 and the first opening OP1 or the second opening OP2, so as to improve the heat dissipation efficiency of the electronic device 100.

[0009] As shown in FIGS. 1 and 3, the first body 110 includes a heat dissipation module 114, an opposite first surface 112 and a second surface 113, and one end 119 of the first body 110 has a slot. The slot defines an accommodation space P for accommodating the rotating member 130. An opening of the slot extends from the first surface 112 to the second surface 113. According to the rotation mode of the rotating member 130, the rotating member 130 can shield a part of the opening, so that the rotating member 130 and the first body 110 form a first opening OP1 or a second opening OP2. The heat dissipation module 114 is located in the heat dissipation channel 111 and corresponds to the rotating member 130. The heat dissipation module 114 is used for dissipating heat from a heat source (not shown), and can discharge the heat energy of the heat source out of the electronic device 100 through the heat dissipation channel 111 and the first opening OP1 or the second opening OP2 of the first body 110. The air inlet of the first body 110 can be located on the second surface 113, but is not limited thereto. The second surface 113 is the bottom of the electronic device 100.

[0010] As shown in FIGS. 1 and 2, the rotating member 130 includes a first rotating member 133 and a second rotating member 134. The first rotating member 133 is pivotally connected to the first body 110. The second rotating member 134 is pivotally connected to the first rotating member 133 and connected to the second body 120. The stop portion 132 is located on the first rotating member 133, and the first rotating member 133 and the second rotating member 134 form a rotating portion 131. The stop portion 132 can be a retaining wall, but is not limited thereto. One end E1 of the second rotating member 134 is fixedly connected to one end 122 of the second body 120, and can be driven by the second body 120 and rotate relative to the first rotating member 133. The other end E2 of the second rotating member 134 is connected to the first rotating member 133. In other words, the second body 120 and the second rotating member 134 do not rotate relative to each other. The second rotating member 134 can be directly connected to a frame 123 of the second body 120, and the second body 120 does not need to form a hole, thereby improving the appearance of the electronic device 100.

[0011] The first rotating member 133 includes a first connecting portion 135, a second connecting portion 136 and a guiding portion 137. The first connecting portion 135 is pivotally connected to the first body 110. The end E2 of the second rotating member 134 is pivotally connected to the second connecting portion 136. The guiding portion 137 is located between the first connecting portion 135 and the second connecting portion 136 and has an arc surface 138. The stop portion 132 is located at one end of the guiding portion 137 away from the second connecting portion 136. The stop portion 132 faces the first body 110, but is not limited thereto.

[0012] Figure 1 shows the rotating member 130 in the first state M1. As shown in Figure 1, when the rotating member 130 is in the first state M1, the stopper portion 132 of the rotating member 130 and the first body 110 form a first opening OP1. The first opening OP1 is located on the second surface 113 of the first body 110. The heat dissipation channel 111 of the first body 110 communicates with the first opening OP1 to form a first heat dissipation flow path HF1. The heat energy in the first body 110 can leave the electronic device 100 with the air flow passing through the first heat dissipation flow path HF1 (the heat dissipation channel 111 and the first opening OP1). The width of the first opening OP1 in the X-axis direction is, for example, 3.5 millimeters, but is not limited thereto.

[0013] When the rotating member 130 is in the first state M1 of Figure 1, the electronic device 100 is in the closed state. In the closed state, the second body 120 is closed on the first body 110, and a display surface 121 of the second body 120 faces the first body 110. The first surface 112 of the first body 110 is located between the second body 120 and the second surface 113. The first rotating member 133 and the second rotating member 134 are located in the accommodation space P. The first body 110 further includes a footrest 115, and the footrest 115 is connected to the second surface 113 and abuts against an object surface (not shown).

[0014] As shown in Figure 3, when the electronic device 100 is to be opened, the second body 120 can be forced to rotate relative to the first body 110, driving the rotating member 130 to rotate relative to the first body 110. The second body 120 first rotates from the position in Figure 1 to the position in Figure 3. The second rotating member 134 of the rotating member 130 includes a rotation end point. In this embodiment, the second rotating member 134 can first be driven by the second body 120 and rotate relative to the first rotating member 133 with the rotation end point E3 as the rotation center. The rotation angle of the second rotating member 134 (the second body 120) can be 50 degrees, but is not limited thereto. At this time, the first rotating member 133 (the stopper portion 132 of the rotating member 130) still cooperates with the first body 110 to form the first opening OP1, and the rotating member 130 is in the first state M1'. A part of the second rotating member 134 is located outside the accommodation space P of the first body 110.

[0015] FIG. 4 is a side sectional view after the second body rotates in FIG. 3. Referring to FIG. 4, the second body 120 can be continuously stressed and rotated from the position in FIG. 3 to the position in FIG. 4. During the rotation of the second body 120, the second rotating member 134 can drive the first rotating member 133 to rotate relative to the first body 110 with the first connecting portion 135 as the rotation axis, so that the second rotating member 134 and the first rotating member 133 are partially located outside the accommodating space P of the first body 110. At this time, the rotation angle of the first rotating member 133 relative to the first body 110 can be 40 degrees, so that the rotation angle of the second body 120 relative to the first body 110 can be 90 degrees, but not limited thereto. The electronic device 100 is in an open state, and the display surface 121 of the second body 120 faces outward for display. The end 122 of the second body 120 can support the surface of an object and lift the first body 110. In other words, the end 122 can be used as a tripod.

[0016] The rotation of the first rotating member 133 causes the stopper portion 132 to move towards the first body 110 and approach the first body 110, so that the first body 110 and the first rotating member 133 (the stopper portion 132 of the rotating member 130) cannot cooperate to form the first opening OP1 (FIG. 3). That is to say, the first heat dissipation channel HF1 is blocked by the stopper portion 132. In this embodiment, the stopper portion 132 abuts against the first body 110, but not limited thereto. At this time, a second opening OP2 is formed between the rotating portion 131 (the first rotating member 133 and the second rotating member 134) of the rotating member 130 and the first body 110, so that the rotating member 130 switches to the second state M2. In the second state M2, the second opening OP2 communicates with the heat dissipation channel 111 to form a second heat dissipation channel HF2. The heat energy in the first body 110 can leave the electronic device 100 with the airflow passing through the second heat dissipation channel HF2 (the heat dissipation channel 111 and the second opening OP2). The second opening OP2 can be formed between the first surface 112 and the second surface 113 of the first body 110.

[0017] In an embodiment not shown, there may be a small gap between the stopper portion 132 and the first body 110, and the size of the gap is much smaller than the size of the second opening OP2, so that the airflow leaves the electronic device 100 from the second opening OP2 (the second heat dissipation channel HF2). In an embodiment not shown, the first body 110 further includes a clamping portion. When the stopper portion 132 approaches the first body 110, the clamping portion can overlap the stopper portion 132 through any known structural interference method to block the first heat dissipation channel HF1.

[0018] FIG. 4 schematically shows, in dots, the rotation end point E3 of the rotating member 130 in the first state M1’ (FIG. 3). Since the first rotating member 133 rotates relative to the first body 110 during the process of the rotating member 130 switching to the second state M2, the second rotating member 134 moves in the -Z axis and +X axis directions along with the first rotating member 133. There is a distance D between the rotation end point E3 of the rotating member 130 in the first state M1 and the rotation end point E4 of the rotating member 130 in the second state M2.

[0019] FIG. 5 is a side sectional view after the second body further rotates in FIG. 4. Referring to FIG. 5, the second body 120 can be further forced to rotate from the position in FIG. 4 to the position in FIG. 5. During the further rotation of the second body 120, the second rotating member 134 further rotates relative to the first rotating member 133 with the rotation end point E4 as the rotation center. At this time, the rotation angle of the second rotating member 134 relative to the first body 110 can be 50 degrees, and the opening angle of the second body 120 relative to the first body 110 can be 140 degrees, but not limited thereto. The rotating member 130 still forms a second opening OP2 with the first body 110. The rotating member 130 is in the second state M2’, and the second opening OP2 and the heat dissipation channel 111 form a second heat dissipation flow path HF2’. The electronic device 100 is still in the on state.

[0020] FIG. 5 schematically shows, in dots, the rotation end point E3 of the rotating member 130 in the first state M1. The first body 110 further includes a first guiding surface S1. The first guiding surface S1 is a curved surface and includes an inflection point B. In the second state M2’, there is a gap G1 between the inflection point B of the first guiding surface S1 and the rotating part 131 in a normal direction C1, and there is a gap G2 between the inflection point B of the first guiding surface S1 and the second body 120 in a tangential direction C2. Here, the gap G1 is greater than the distance D by 2, and the gap G2 is greater than 3 times the gap G1, but not limited thereto. The gap G2 is, for example, 17.3 mm, but not limited thereto.

[0021] In the second state M2’, the rotating part 131 (the first rotating member 133 and the second rotating member 134) forms a second guiding surface S2. Specifically, the guiding part 137 and the second connecting part 136 of the first rotating member 133 and the second rotating member 134 form the second guiding surface S2. The length of the first guiding surface S1 is less than the length of the second guiding surface S2. According to Bernoulli's law, the length of the path on the surface of an object will cause a difference in the flow velocity of the air flow. Therefore, the flow velocity of the air flow flowing out from the heat dissipation channel 111 and guided by the first guiding surface S1 is greater than the flow velocity of the air flow guided by the second guiding surface S2, and the air flow pressure guided by the first guiding surface S1 is greater than the air flow pressure guided by the second guiding surface S2.

[0022] When the airflow leaves the first body 110, the airflow flows along the display surface 121 of the second body 120 and leaves the electronic device 100. At this time, the airflow far from the display surface 121 (i.e., the airflow guided by the first guiding surface S1) has a greater pressure, while the airflow adjacent to the display surface 121 (i.e., the airflow guided by the second guiding surface S2) has a smaller pressure, so that the overall airflow can flow on the surface of the second body 120. Thereby, it is possible to prevent the hot air flowing out from the first body 110 from moving towards the user (i.e., flowing away from the second body 120) or flowing back into the first body 110, causing interference and discomfort to the user.

[0023] According to the above, the electronic device 100 can dissipate heat through different heat dissipation channels according to the rotation state of the rotating member 130. When the rotating member 130 is in the first state M1, the electronic device 100 dissipates heat through the first heat dissipation channel HF1 (the heat dissipation channel 111 and the first opening OP1). When the rotating member 130 is in the second states M2, M2', the electronic device 100 dissipates heat through the second heat dissipation channels HF2, HF2' (the heat dissipation channel 111 and the second opening OP2).

[0024] The rotation steps of the rotating member 130 are not limited to this embodiment. For example, in one embodiment, the second body 120 (Figure 1) in the closed state can be forced to drive the second rotating member 134 to rotate 100 degrees relative to the first rotating member 133 (the first body 110) first, so that the electronic device 100 is in the open state. At this time, the first rotating member 133 does not rotate relative to the first body 110, so that the first rotating member 133 (the stopper 132) and the first body 110 form the first opening OP1, and the rotating member 130 is in the first state M1. Then, the second body 120 in the open state can be forced to drive the first rotating member 133 and the second rotating member 134 to rotate relative to the first body 110, so that the opening angle of the second body 120 relative to the first body 110 is 140 degrees. At this time, the electronic device 100 is still in the open state, and the rotating member 130 (the first rotating member 133 and the second rotating member 134) and the first body 110 form the second opening OP2, so that the rotating member 130 is in the second state M2.

[0025] In this embodiment, the rotating member 130 can limit the relative rotation angle of the first rotating member 133 and the second rotating member 134 through any known structural interference method, which will not be described additionally here.

[0026] FIG. 6 is a bottom view of the electronic device of FIG. 1. FIG. 7 is a rear view of the electronic device of FIG. 1. Please refer to FIGS. 6 and 7 simultaneously. The orthographic projection of the rotating member 130 on the first body 110 overlaps with the heat dissipation module 114. Thereby, the heat dissipation module 114 can quickly transfer the airflow with high thermal energy to the outside of the electronic device 100 through the first opening OP1 or the second opening OP2 (i.e., the first heat dissipation channel HF1 or the second heat dissipation channel HF2) generated by the rotating member 130 and the first body 110, so as to improve the heat dissipation efficiency of the electronic device 100. Specifically, the heat dissipation module 114 may include a heat dissipation fin 116 and a fan 117. The orthographic projection of the rotating member 130 on the first body 110 overlaps with the heat dissipation fin 116, and an air outlet 118 of the fan 117 corresponds to the rotating member 130.

[0027] According to the setting manner of the second rotating member 134, the electronic device 100 of this embodiment is a three-section electronic device, but is not limited thereto. That is, from the perspective of FIG. 7, the first body 110 and the second body 120 are divided into three sections A1, A2, and A3 in appearance by the rotating member 130. In a three-section electronic device, the number of the second rotating members 134 can be one and extends from section A1 to section A3.

[0028] FIG. 8 is a rear view of an electronic device according to another embodiment of the present invention. Please refer to FIGS. 7 and 8 simultaneously. The electronic device 100a of this embodiment is similar to the previous embodiment, and the difference between the two is that the electronic device 100a of this embodiment is a five-section electronic device. That is, from the perspective of FIG. 8, the first body 110 and the second body 120 are divided into five sections A1, A2, A3, A4, and A5 in appearance by the rotating member. In a five-section electronic device, the number of the second rotating members 134 can be two. One second rotating member 134 extends from section A1 to the left side of section A3, and the other second rotating member 134 extends from the right side of section A3 to section A5.

[0029] FIG. 9 is a side cross-sectional view of an electronic device according to another embodiment of the present invention. FIG. 10 is a side cross-sectional view after the second body in FIG. 9 is opened. FIG. 11 is a top view of the electronic device in FIG. 10. Please refer to FIGS. 1, 9 to 11 simultaneously. The electronic device 100b in this embodiment is similar to the previous embodiment. The difference between the two is that one end E5 of the rotating part 131b in this embodiment is connected to the second body 120, and the other end E6 of the rotating part 131b is connected to the stopping part 132b. The stopping part 132b can be a bump. The rotating part 131b is generally in an L shape, and the rotating part 131b and the stopping part 132b together form a T shape, but it is not limited thereto. The rotation end point E7 of the rotating member 130b is located between the two ends E5 and E6 and deviates from the connection line of the two ends E5 and E6. The orthographic projection of the rotating member 130b on the first body 110b is offset from the heat dissipation module 114.

[0030] As shown in FIG. 9, when the rotating member 130b is in the first state M1, the first body 110b and the rotating part 131b of the rotating member 130b together form a first opening OP3. One end 139 of the stopping part 132b is located outside the accommodation space P of the first body 110b. The first opening OP3 is located on the second surface 113 of the first body 110b. The electronic device 100b is in a closed state.

[0031] As shown in FIG. 10, when the second body 120b is forced to open relative to the first body 110b, the second body 120b drives the rotating member 130b to rotate. The rotating member 130b rotates relative to the first body 110b and moves in the -X axis direction, so that the end 139 of the stopping part 132b moves into the accommodation space P and abuts against the first body 110b. The first body 110b and the rotating part 131b of the rotating member 130b together form a second opening OP4, and the rotating member 130b is in the second state M2. The second opening OP4 is located on the first surface 112 of the first body 110b. At this time, the electronic device 100b is in an open state.

[0032] FIG. 10 schematically marks the rotation end point E7 of the rotating member 130b in the first state M1 with a dot. There is a certain distance between the rotation end point E7 of the rotating member 130b in the first state M1 and the rotation end point E8 of the rotating member 130 in the second state M2. The electronic device 100b in this embodiment has the same effect as the previous embodiment, and will not be elaborated here.

[0033] FIG. 12 is a top view of an electronic device according to another embodiment of the present invention. Please refer to FIGS. 11 and 12 simultaneously. The electronic device 100c of this embodiment is similar to the previous embodiment. The difference between the two is that the electronic device 100c of this embodiment is a five-section electronic device 100c. The number of rotating members 130c is two, and the heat dissipation module 114 can be located between the two rotating members 130c. The electronic device 100c of this embodiment has the same effect as the previous embodiment and will not be elaborated here.

[0034] In summary, the first body of the electronic device of the present invention can cooperate with the rotating member to form different openings (the first opening or the second opening) in different states. Thereby, the heat dissipation channel of the first body can communicate with different openings, and dissipate heat through different heat dissipation channels (the first heat dissipation channel or the second heat dissipation channel), so as to change the air outlet position of the electronic device and improve the heat dissipation efficiency of the electronic device.
