When the first body rotates and unfolds relative to the second body, the cam portion abuts against the elastic sheet to drive the door cover to rotate and unfold relative to the second body.

Based on the above, since the second body of the foldable electronic device is provided with a movable door cover, the door cover further has an elastic piece extending toward the inside of the second body and the elastic piece is located on the moving path of the cam portion of the first body. Accordingly, when the first body is unfolded relative to the second body, the cam part can abut against and drive the shrapnel to rotate and unfold the door cover, so that the door cover and the second body can communicate with the external environment and The opening inside the second body. In addition, the elastic piece abuts against (or is abutted against) the cam portion of the first body, so that the elastic piece forms a buffer between the first body and the door cover to achieve a shock-absorbing effect.

FIG. 1 is a schematic diagram of a foldable electronic device according to an embodiment of the invention. FIG. 2 is an exploded view of partial components of the foldable electronic device in FIG. 1 . FIG. 3 shows the door cover of FIG. 2 from another perspective. Please refer to FIG. 1 to FIG. 3 at the same time. In this embodiment, a foldable electronic device 100 , such as a notebook computer, includes a first body 110 , a second body 120 , a hinge 130 and a door cover 140 . The first body 110 has a cam portion 111 . The rotating shaft 130 connects the first body 110 and the second body 120 . The first body 110 and the second body 120 are rotated to open and close relative to each other through the rotating shaft 130 , and the cam portion 111 is rotated relative to the axis X1 of the rotating shaft 130 . The door cover 140 is pivotally connected to the second body 120 to rotate relative to the second body 120 to open and close. The door cover 140 has an elastic piece 142 extending toward the inside of the second body 120 and located on a moving path of the cam portion 111 . When the first body 110 rotates and unfolds relative to the second body 120 , the cam portion 111 pushes against the elastic piece 142 to drive the door cover 140 to rotate and unfold relative to the second body 120 , so that the gap between the door cover 140 and the second body 120 An opening OP is formed therebetween.

Please refer to FIG. 2 and FIG. 3 again. In detail, the rotating shaft 130 of this embodiment is connected to the pivotal portion 112 of the first body 110 and the pivotal portion 122 of the second body 120, and as shown in FIG. The parts 112, 122 are in a state of interlacing along the axis X1. Therefore, for the first body 110 , the cam portion 111 is equivalent to adjacent to the pivot portion 112 along the axis X1 , so that the cam portion 111 can rotate around the axis X1 as its rotation axis.

Furthermore, the door cover 140 is pivotally connected to the second body 120 by its shaft portion 141, and the door cover 140 has a pivot side S1 and an opening side S2 opposite to each other, and the pivot side S1 is pivotally connected to the second body 120 due to the aforementioned shaft portion 141. Two body 120. The opening side S2 forms an opening OP relative to the second body 120 after the door cover 140 is unfolded. More importantly, the elastic piece 142 of this embodiment is located at the opening side S2 and can be smoothly seated on the moving path of the cam portion 111 , which will be further described later. In addition, the foldable electronic device 100 also includes a torsion spring 150, which is divided into a winding portion 152 and two opposite branches 151, 153, wherein the winding portion 152 is sleeved on the shaft portion 141 of the door cover 140, and the branch 151 passes through The opening 143 provided in the door cover 140 is considered to be in contact with the door cover 140, and the branch 153 is in contact with the second body 120, so that the elastic force generated by the torsion spring 150 can achieve constant driving of the door cover 140 to close on the second body. The effect of the second body 120 is that the force applied by the cam portion 111 to drive the elastic piece 142 (the door cover 140 unfolds) is opposite to the elastic force of the torsion spring 150 .

In addition, as can be seen from FIG. 1 (and subsequent FIG. 6 ), when the first body 110 of the foldable electronic device 100 of this embodiment is unfolded to an angle with respect to the second body 120 , it can further use the hinge part 112 ( push against the platform) to lift the second body 120 to facilitate the user's operation.

4 to 6 are partial cross-sectional views of the foldable electronic device in different states. FIG. 7 shows some components of the foldable electronic device in FIG. 1 in a top view, in which a part of the second body 120 is particularly omitted to facilitate identification of components disposed therein. Please refer to FIG. 7 and compare one of FIGS. 4 to 6. In this embodiment, the foldable electronic device 100 further includes a heat dissipation module 160, which is composed of a fan 161, a heat pipe 163 and a heat dissipation fin 162. The fan 161 is a centrifugal fan, the heat dissipation fins 162 are arranged at the air outlet of the fan 161, and one end of the heat pipe 163 runs through and contacts the heat sources H1 and H2 (for example, the central processing unit) of the foldable electronic device 100 in the second body 120 and the display chip), the other end of the heat pipe 163 is in contact with the heat dissipation fins 162, so that the heat generated by the heat sources H1 and H2 is transmitted to the heat dissipation fins 162 through the heat pipe 163, so that the airflow generated by the fan 161 passes through the heat dissipation fins 162 and Take the heat off it.

As mentioned above, during the unfolding process of the foldable electronic device 100, the door cover 140 will also be driven open to form the opening OP, and the cooling fins 162 will correspond to the opening OP, so the airflow generated by the fan 161 will pass through the heat dissipation in sequence. The fins 162 and the opening OP discharge the second body 120 .

Further, please refer to FIG. 7 again, the opening OP of this embodiment can be divided into two subsections OP1 and OP2 in essence, wherein the fan 161 and the cooling fins 162 correspond to the subsection OP1, so that the subsection OP1 communicates. The heat dissipation fins 162 are connected to the external environment. That is to say, the foldable electronic device 100 of this embodiment further includes a shield 170, which is arranged in the second body 120 and is used to block between the two sections OP1 and OP2, so that the two sections OP1 , OP2 is a state that is independent of each other and does not affect each other. In this way, the airflow generated by the fan 161 can be discharged from the second body 120 through the cooling fins 162 and the section OP1 of the opening OP. In contrast, another section OP2 is used to communicate with the external environment and the air inlet 161a of the fan 161, so the air in the external environment can enter the second body 120 through the section OP2, and then enter the fan 161 through the air inlet 161a . In addition, the airflow entering the second body 120 can first dissipate heat from the heat sources H1 and H2 , which contributes to the heat dissipation effect of this embodiment, as shown by the dotted arrows in FIG. 7 .

In other words, the opening OP can provide multiple applications for the heat dissipation module 160 , including exhausting hot air or allowing cold air from the external environment to enter, so as to effectively improve the heat dissipation performance of the foldable electronic device 100 . The scope and quantity of the sub-sections OP1 and OP2 are not limited here, and the designer can make appropriate adjustments according to the cooling requirements of the foldable electronic device 100 .

To sum up, in the above-mentioned embodiments of the new creation, since the second body of the foldable electronic device is provided with a movable door cover, the door cover further has elastic pieces extending toward the inside of the second body and the elastic pieces are located On the moving path of the cam portion of the first body. Accordingly, when the first body is unfolded relative to the second body, the cam part can abut against and drive the shrapnel to rotate and unfold the door cover, so that the door cover and the second body can communicate with the external environment and The opening inside the second body. In addition, in addition to being driven by the above-mentioned cam portion, the elastic piece can also continuously abut against (or be abutted against) the cam portion of the first body, so it is beneficial for the elastic piece to form a gap between the first body and the door cover. The buffer structure achieves the effect of shock absorption (or shock suppression).

In addition, in addition to the torsion spring used to drive the door cover to reset, the door cover can also achieve the same shock absorption (or shock suppression) effect as the aforementioned shrapnel through the torsion spring on the pivoted side, so as to prevent the machine body or the door cover from being damaged due to vibration. And produce abnormal sound.

On the other hand, the opening formed by the door cover and the second body can further cooperate with the heat dissipation module inside the foldable electronic device to improve its heat dissipation efficiency. In one embodiment, at least a part of the opening can pass through the airflow generated by the fan, so that the heat absorbed by the airflow passing through the cooling fins can be discharged from the second body. In another embodiment, the opening can be divided into two sections, and a blocking member is used to block between the two sections, so that the two sections are independent from each other and do not affect each other. In this way, the airflow from the fan can discharge the hot air through one section, while the cold airflow from the external environment can flow into the second body and the air inlet of the fan from the other section. Due to the segmented structure of the opening, the heat dissipation module can improve its heat dissipation capability for the heat source.
