The drive rod 42 in the oblique guide groove 40 is movable upward from the cover position shown in FIG. 2 along the oblique guide groove 40 to the exposed position as shown in FIG. 5, thereby driving the plurality of shielding blades 44. The position from which the first opening 18 is closed is pivoted to a position where the first opening 18 is exposed, so that the heat dissipating unit 12 can dissipate heat by using the exposed first opening 18. Further, in terms of the interlocking of the second shielding structure 28, as can be seen from Fig. 1, Fig. 3, and Fig. 4, the turntable 48 is rotated 180 degrees from the position shown in Fig. 1 to When the second positioning portion 54 shown in FIG. 4 is not in contact with the second driving piece 60, the turntable base 48 can push the second driving piece 60 to move outward relative to the turntable base 48 from the position as shown in FIG. As shown in FIG. 4 (at this time, the second spring 30 is in a compressed state), at the same time, as the second driving piece 60 moves, the second shielding portion 58 can cover the second opening from the cover. The position of 20 is translated relative to the outer casing 14 to a position where the second opening 20 is exposed, so that the heat dissipating unit 12 can be dissipated by the exposed second opening 20, for example, see Fig. 6, which is the fourth figure. A side view of the electronic device 10 placed on the plane P. As can be seen from FIGS. 4 and 6, the electronic device 10 can be placed on the plane P at this time.

On the other hand, when the electronic device 10 is in a situation where it is required to be waterproof and dustproof (for example, when the electronic device 10 is operated outdoors or in a surrounding environment), the user can grasp the handle 50 to drive the turntable. The seat 48 is rotated from the position shown in FIG. 4 to the position shown in FIG. 1, during which the elastic force provided by the first spring 26 and the second spring 30 respectively drives the first driving piece 36 and The second driving piece 60 is in contact with the first positioning portion 52 and the second positioning portion 54, respectively. That is, after the turntable 48 is rotated 180 degrees from the position shown in FIG. 4 to the position shown in FIG. 1, the elastic force provided by the first spring 26 in the compressed state as shown in FIG. That is, the first driving piece 36 can be pushed to move inward from the position shown in FIG. 5 with respect to the turntable seat 48 to the position shown in FIG. 2, and the second spring in the compressed state as shown in FIG. 4 The spring force provided by 30 pushes the second drive piece 60 to move inwardly relative to the turntable base 48 from the position shown in Fig. 4 to the position shown in Fig. 3. At the same time, as the first driving piece 36 moves, the driving rod 42 can be moved downward from the exposed position as shown in FIG. 5 along the oblique guiding groove 40 to the closing position as shown in FIG. The plurality of shielding blades 44 are driven to pivot from a position where the first opening 18 is exposed to a position where the first opening 18 is closed, and the second shielding portion 58 may be opposite to the second driving piece 60 as the second driving piece 60 moves. The outer casing 14 is translated from a position where the second opening 20 is exposed to cover the second opening 20 location. In this way, the first opening 18 and the second opening 20 on the outer casing 14 can be covered by the plurality of shielding blades 44 and the second shielding portion 58, respectively, thereby exerting a waterproof and dustproof effect.

It should be noted that the configuration of the first shielding structure and the second shielding structure on the outer casing may not be limited to the above embodiment. For example, the present invention may be configured by using a linkage mechanism only with a first shielding structure to be disposed in the corresponding Positioning the first shielding structure at a position corresponding to the first opening and the second opening, disposing the second shielding structure at a position corresponding to the second opening, or respectively configuring the second shielding structure The design of the position corresponding to the first opening and the second opening depends on the actual application requirements of the electronic device of the present invention as to which configuration is adopted.

The linkage mechanism 16' includes a first shielding structure 22, a first spring 26, a second shielding structure 28, and a second The spring 30, and a turntable 24', includes a base 46, a handle 50, and a turntable seat 48'. In this embodiment, the turntable base 48' has a first positioning portion 52, a second positioning portion 54, and at least one adjustment groove 53 (one shown in FIG. 7, but not limited thereto), the adjustment groove 53 The recessed depth is smaller than the recessed depth of the first positioning portion 52, and the adjusting recess 53 is for engaging with the first driving piece 36 of the first driving portion 32, that is, when the turntable 48' is rotated to When the first driving piece 36 of the first driving portion 32 is aligned with the position of the adjusting groove 53, the elastic force provided by the first spring 26 can push the first driving piece 36 to engage with the adjusting groove 53, at this time, due to the adjustment The concave depth of the groove 53 is smaller than the concave depth of the first positioning portion 52, so the first driving piece 36 can only drive the plurality of shielding blades 44 to partially cover the first portion. The opening 18 does not completely shield the first opening 18, thereby achieving the purpose of partially exposing the first opening 18. The design of the above-mentioned partially exposed opening can also be applied to the second shielding structure. The related interlocking design can be analogized with reference to the above embodiments, and details are not described herein again.

In addition, the interlocking design of the first shielding structure is not limited to the above embodiment, and the design of the driving rod of the first shielding portion can be directly driven by the first driving piece.

As shown in FIG. 8 and FIG. 9 , the first shielding structure 22 ′ has a first driving piece 36 ′ and a first shielding part 34 , and the first driving piece 36 ′ is extended to the driving rod 42 of the first shielding part 34 . Moreover, it can be selectively superposed on the turntable base 48 or abutted with the first positioning portion 52 as the turntable base 48 rotates. In more detail, since the turntable holder 48 is rotated to the position where the first driving piece 36' as shown in FIG. 8 is superposed on the turntable base 48, the first driving piece 36' is pushed upward, and thus is directly connected to The drive rod 42 of the first drive piece 36' can drive the plurality of shielding blades 44 to pivot to a position where the first opening 18 is exposed as the first drive piece 36' moves upward. On the other hand, since the turntable base 48 is rotated to a position where the first driving piece 36' as shown in FIG. 9 abuts on the first positioning portion 52 of the turntable base 48, the first driving piece 36' is engaged with The first positioning portion 52 moves downward, so that the driving rod 42 directly connected to the first driving piece 36' can drive the plurality of shielding blades 44 to pivot to the cover as the first driving piece 36' moves downward. The position where the first opening 18 is exposed is occupied.
