Therefore, these users hope that the number of heat dissipation holes is large to ensure the heat dissipation efficiency.

[0035] Some users usually use the system in light load scenarios such as office, web browsing, etc. The heat generated in this scenario is small, so these users hope that the number of heat dissipation holes is small to reduce the noise volume transmitted through the heat dissipation holes; while some users usually use in heavy load scenarios such as games, graphics rendering, model training, etc. The heat generated in this scenario is large, so these users hope that the number of heat dissipation holes is large to ensure the heat dissipation efficiency.

[0036] However, the case in the related art cannot simultaneously meet the use requirements of the above two groups of users.

[0037] The inventors of the present application found that the part of the case can be provided as two layers, i.e. a first plate body and a second plate body, and the first plate body and the second plate body are connected through a movable mechanism to enable the first plate body and the second plate body to move relative to each other, thereby switching between forming a heat conduction channel and closing the heat conduction channel. In this way, the heat conduction channel can be opened in a heavy load scenario, and the heat conduction channel can be closed in a light load scenario to meet different user needs for heat dissipation.

[0038] First aspect

[0039] The present disclosure provides a plate body structure 10 applied to a case, as shown in Figures 1 to 7As shown, the plate structure 10 can include: a first plate body 11, a second plate body 12, and a movable mechanism 13, the second plate body 12 is stacked on one side of the first plate body 11; the movable mechanism 13 is connected with the first plate body 11 and the second plate body 12, and the second plate body 12 can move away from or close to the first plate body 11 through the movable mechanism 13, so that the plate structure 10 has a first use mode and a second use mode; in the first use mode, the second plate body 12 moves away from the first plate body 11, and the first plate body 11 and the second plate body 12 cooperate to form a heat conduction channel; in the second use mode, the second plate body 12 moves close to the first plate body 11, and the heat conduction channel is closed; wherein in the first use mode and the second use mode, the projection area of the second plate body 12 on the first plate body 11 is unchanged.

[0040] The case can be an external shell of an electronic device to physically (e.g. anti-collision) protect the electronic and non-electronic components inside. The case can be a structure enclosed by multiple plate bodies to form an internal accommodating chamber, one or more of which can be the plate structure 10.

[0041] The first plate body 11 can be a solid plate to ensure the strength of the first plate body 11; it can also be a hollow plate to reduce the weight of the first plate body 11. It can be a metal plate to improve the heat conduction performance of the first plate body 11.

[0042] The second plate body 12 can be a solid plate to ensure the strength of the second plate body 12; it can also be a hollow plate to reduce the weight of the second plate body 12. It can be a metal plate to improve the heat conduction performance of the second plate body 12. The second plate body 12 is stacked on one side of the first plate body 11, and the orthographic projection of the second plate body 12 on the first plate body 11 can cover part or all of the first plate body 11, such as: Figure 1 and Figure 2 As shown, the orthographic projection of the second plate body 12 on the first plate body 11 covers part of the first plate body 11.

[0043] The movable mechanism 13 can be connected with the first plate body 11 and the second plate body 12 respectively, so that the second plate body 12 is maintained in the stacked state with the first plate body 11, and the second plate body 12 can move towards or away from the first plate body 11 under the action of the movable mechanism 13; in the first use mode, the second plate body 12 can move away from the first plate body 11, and the distance between the first plate body 11 and the second plate body 12 increases after movement, so that a heat conduction channel can be formed by the first plate body 11, the second plate body 12 and the gap therebetween; in the second use mode, the second plate body 12 can move towards the first plate body 11, and the distance between the first plate body 11 and the second plate body 12 can be reduced to zero after movement, so as to close the heat conduction channel. Here, in the case that the plate body structure 10 is in the first use mode, the area of the second plate body 12 projected onto the first plate body 11 is a first area; in the case that the plate body structure 10 is in the second use mode, the area of the second plate body 12 projected onto the first plate body 11 is a second area, and the second area is equal to the first area; for example, in the process of switching between the first use mode and the second use mode, the second plate body 12 translates away from or towards the first plate body 11, so that the area of the second plate body 12 projected onto the first plate body 11 remains unchanged before and after movement.

[0044] In an example, the cabinet is enclosed by a plurality of plate bodies, one of which is the plate body structure 10, as shown in Figures 1 to 7 As shown, the plate body structure 10 can include: a first plate body 11, a second plate body 12 and a movable mechanism 13, one side surface of the first plate body 11 forms a partial outer surface of the cabinet, the second plate body 12 is stacked on the other side surface of the first plate body 11, so that the surface of the second plate body 12 facing away from the first surface 113 forms a partial inner surface of the cabinet; the movable mechanism 13 is connected with the first plate body 11 and the second plate body 12, and the second plate body 12 can move away from or towards the first plate body 11 through the movable mechanism 13, so that the plate body structure 10 has a first use mode and a second use mode; in the first use mode, the second plate body 12 moves away from the first plate body 11, and the first plate body 11 and the second plate body 12 cooperate to form a heat conduction channel; in the second use mode, the second plate body 12 moves towards the first plate body 11, and the heat conduction channel is closed; wherein in the first use mode and the second use mode, the projection area of the second plate body 12 onto the first plate body 11 remains unchanged. It can be understood that the first plate body 11 can also correspond to the inside of the cabinet, and the second plate body 12 corresponds to the outside of the cabinet, and the following description is made with the first plate body 11 corresponding to the outside of the cabinet and the second plate body 12 corresponding to the inside of the cabinet.

[0045] In the embodiment, the plate body structure 10 can include a first plate body 11, a second plate body 12, and a movable mechanism 13. The first plate body 11 and the second plate body 12 are stacked and connected by the movable mechanism 13 to maintain the stacked state. The second plate body 12 can move relative to the first plate body 11 by the movable mechanism 13 to form a heat conduction channel with the first plate body 11 after moving away from the first plate body 11, and the heat conduction channel can be closed after moving towards the first plate body 11. In this way, in a heavy load scenario, the user can form a heat conduction channel by moving the movable mechanism 13 to dissipate heat. In the case of switching to a light load scenario, the user can close the heat conduction channel by moving the movable mechanism 13 and dissipate heat by the heat dissipation of the plate body structure 10 itself. In addition, in the first use mode and the second use mode, the projection area of the second plate body 12 on the first plate body 11 is unchanged, so that the movement track of the second plate body 12 is translation. The translation arrangement is simple and easy to operate.

[0046] In some embodiments, referring to Figures 1 to 5 The first plate body 11 and the second plate body 12 have at least one first region 111 opposite each other. The second plate body 12 and the first plate body 11 have at least one second region 121 opposite each other. In the first use mode, the first region 111, the second region 121, and the gap between the first plate body 11 and the second plate body 12 form a heat conduction channel. The thickness of the first plate body 11 in the first region 111 is less than the thickness of the first plate body 11 outside the first region 111. The thickness of the second plate body 12 in the second region 121 is less than the thickness of the second plate body 12 outside the second region 121.

[0047] That is, the first plate body 11 can have a first region 111 and a third region 112. The second plate body 12 can have a second region 121 and a fourth region 122. The first region 111 can be opposite one of the second region 121 and the fourth region 122. The third region 112 can be opposite the other of the second region 121 and the fourth region 122. In the first use mode, the first region 111, the second region 121, and the gap between the first plate body 11 and the second plate body 12 can form a heat conduction channel based on the movement of the movable mechanism 13. In the second use mode, the first plate body 11 and the second plate body 12 can be reset based on the movement of the movable mechanism 13. In the case that the first region 111 and the second region 121 are opposite each other, the heat conduction channel extends in a straight line. In the case that the first region 111 and the fourth region 122 are opposite each other, the first region 111 and the second region 121 are not opposite each other, or are misaligned with each other, so that the heat conduction channel extends in a curved track. For example, referring to Figure 2 The first region 111 and the fourth region 122 are opposite each other, and the heat conduction channel extends in a curved track.

[0048] In the first plate body 11, the thickness of the first region 111 is less than the thickness of the first plate body 11 except the first region 111, so that the heat on one side of the first plate body 11 is preferentially transmitted to the other side of the first plate body 11 through the first region 111 with small thickness; similarly, in the second plate body 12, the thickness of the second region 121 is less than the thickness of the second plate body 12 except the second region 121, so that the heat on one side of the second plate body 12 is preferentially transmitted to the other side of the second plate body 12 through the second region 121 with small thickness; thus, in the first use mode, the heat on the side of the second plate body 12 facing away from the first plate body 11 (such as the inside of the case) can be preferentially transmitted to the side of the first plate body 11 facing away from the second plate body 12 (such as the outside of the case) through the gap between the second region 121, the second plate body 12 and the first plate body 11 and the heat conduction channel formed by the first region 111, thereby achieving the reduction of the temperature on the inside of the case.

[0049] In the present embodiment, by providing the first region 111 with a thickness smaller than other regions of the first plate body 11 on the first plate body 11, the second region 121 with a thickness smaller than other regions of the second plate body 12 on the second plate body 12, and based on the movement of the activity mechanism 13 to have a gap between the first plate body 11 and the second plate body 12, the second region 121, the gap and the first region 111 form a heat conduction channel (suitable for heavy load scenarios); and based on the movement of the activity mechanism 13 to close the heat conduction channel, the first plate body 11 and the second plate body 12 are attached to each other to ensure the structural strength of the plate structure 10 and reduce the propagation of noise (suitable for light load scenarios).

[0050] In some embodiments, referring to Figures 1 to 5 As shown, the second region 121 is a through hole, and the first plate body 11 is provided with a first protrusion corresponding to the third region 112 of the second region 121, and the first protrusion is located in the through hole of the second region 121 in the second use mode; and / or, the first region 111 is a through hole, and the second plate body 12 is provided with a second protrusion corresponding to the fourth region 122 of the first region 111, and the second protrusion is located in the through hole of the first region 111 in the second use mode.

[0051] That is, in the case that the first region 111 of the first plate body 11 and the fourth region 122 of the second plate body 12 are opposite, and the third region 112 of the first plate body 11 and the second region 121 of the second plate body 12 are opposite, the second region 121 of the second plate body 12 can be a through hole, and the third region 112 of the first plate body 11 corresponding to the second region 121 has a first protrusion and can extend into the through hole of the second region 121 in the case that the heat conduction channel is closed; or, in the case that the first region 111 of the first plate body 11 and the fourth region 122 of the second plate body 12 are opposite, and the third region 112 of the first plate body 11 and the second region 121 of the second plate body 12 are opposite, the first region 111 of the first plate body 11 can be a through hole, and the fourth region 122 of the second plate body 12 corresponding to the first region 111 has a second protrusion and can extend into the through hole of the first region 111 in the case that the heat conduction channel is closed; or, in the case that the first region 111 of the first plate body 11 and the fourth region 122 of the second plate body 12 are opposite, and the third region 112 of the first plate body 11 and the second region 121 of the second plate body 12 are opposite, the second region 121 of the second plate body 12 can be a through hole, and the third region 112 of the first plate body 11 corresponding to the second region 121 has a first protrusion and can extend into the through hole of the second region 121 in the case that the heat conduction channel is closed, and the first region 111 of the first plate body 11 can be a through hole, and the fourth region 122 of the second plate body 12 corresponding to the first region 111 has a second protrusion and can extend into the through hole of the first region 111 in the case that the heat conduction channel is closed.

[0052] In the embodiment, in the case that the heat conduction channel is opened, the gap between the second region 121, the first plate body 11 and the second plate body 12, the first region 111 form a heat conduction channel, and the second region 121 and / or the first region 111 are through holes, so that heat can flow out of the case quickly and smoothly through the heat conduction channel; in the case that the heat conduction channel is closed, the first protrusion corresponds to the through hole of the second region 121 and / or the second protrusion corresponds to the through hole of the first region 111, so that the first plate body 11 and the second plate body 12 can be concave-convex matched, thereby improving the structural strength of the plate body structure 10 in the second use mode.

[0053] In some embodiments, the first region 111 is at least one of the following: a plate piece, a through hole, a filter screen; and / or, the second region 121 is at least one of the following: a plate piece, a through hole, a filter screen.

[0054] The first region 111 can be at least one of the following: a plate, a through hole, or a filter. That is, the first region 111 can be a non-through plate, and the thickness of the plate in the first region 111 can be less than the thickness of other regions of the first plate 11. For example, the portion of the first plate 11 corresponding to the first region 111 can be a thin plate with a thickness less than other regions of the first plate 11. The first region 111 can also have a large through hole; or it can have multiple small holes to form a filter. The thin plate, through hole, and filter allow heat from the side of the second plate 12 facing away from the first plate 11 to be quickly transferred through the first region 111 to the side of the first plate 11 facing away from the second plate 12. The description of the second region 121, referring to the first region 111, will not be repeated here.

[0055] In this embodiment, multiple settings for the first region 111 and the second region 121 are provided to allow for flexible selection and setting.

[0056] In some embodiments, see Figures 1 to 4 and Figure 6 , Figure 7 As shown, the active mechanism 13 may include: a first guide member 131 and a second guide member 132. The first guide member 131 is movably disposed on a first surface 113 on the side of the first plate 11 corresponding to the second plate 12. The first guide member 131 is located at one end of the second plate 12 and is provided with a first inclined surface 1311. The second guide member 132 is movably disposed on the first surface 113. The second guide member 132 is located at the other end of the second plate 12 and is provided with a second inclined surface 1321 on the surface of the second guide member 132 near the first guide member 131. The first use mold In one mode, at least one of the first guide member 131 and the second guide member 132 is activated to reduce the distance between the first guide member 131 and the second guide member 132, and the second plate 12 moves away from the first plate 11 along the first inclined plane 1311 and the second inclined plane 1321; in the second mode, at least one of the first guide member 131 and the second guide member 132 is activated to increase the distance between the first guide member 131 and the second guide member 132, and the second plate 12 moves closer to the first plate 11 along the first inclined plane 1311 and the second inclined plane 1321.

[0057] Or it can be said that the second plate body 12 is stacked on the first surface 113 of the first plate body 11, the first guide 131 and the second guide 132 are also arranged on the first surface 113 of the first plate body 11, and abut the two ends of the second plate body 12 respectively, and the first guide 131 and the second guide 132 abutting the two surfaces of the second plate body 12 are respectively provided with the first inclined surface 1311 and the second inclined surface 1321, and in the process of reducing or increasing the distance between the first guide 131 and the second guide 132, the two ends of the second plate body 12 can move away from the first plate body 11 or close to the first plate body 11 along the first inclined surface 1311 and the second inclined surface 1321 respectively. In the first use mode, the first guide 131 can move towards the second guide 132, the second guide 132 can move towards the first guide 131, or the first guide 131 and the second guide 132 can move towards each other at the same time; in the second use mode, the first guide 131 can move away from the second guide 132, the second guide 132 can move away from the first guide 131, or the first guide 131 and the second guide 132 can move away from each other at the same time.

[0058] In an example, referring to Figures 2 to 4 and Figure 6 , Figure 7 , the angle between the first inclined surface 1311 and the first surface 113 is an obtuse angle, the angle between the second inclined surface 1321 and the first surface 113 is an obtuse angle, the two ends of the second plate body 12 abut the first inclined surface 1311 and the second inclined surface 1321 respectively, and in the process of reducing the distance between the first guide 131 and the second guide 132, the second plate body 12 moves away from the first plate body 11 along the first inclined surface 1311 and the second inclined surface 1321 to form a heat conduction channel; in the process of increasing the distance between the first guide 131 and the second guide 132, the second plate body 12 moves close to the first plate body 11 along the first inclined surface 1311 and the second inclined surface 1321 to close the heat conduction channel.

[0059] In this embodiment, the second plate body 12 changes the distance from the first plate body 11 based on the movement of at least one of the first guide 131 and the second guide 132, thereby opening and closing the guide channel, and since the second plate body 12 moves along the first inclined surface 1311 of the first guide 131 and the second inclined surface 1321 of the second guide 132 during the process of approaching or moving away from the first plate body 11, the movement process of the second plate body 12 is more stable.

[0060] In some embodiments, referring to Figures 1 to 4As shown, the movable mechanism 13 may further include: a first gear 133, a second gear 134, and a third gear 135. The first gear 133 is disposed on the first surface 113 corresponding to the side of the second plate 12. The second gear 134 meshes with the side of the first gear 133 near the first guide member 131, and the second gear 134 meshes with the first guide member 131. The third gear 135 meshes with the side of the first gear 133 near the second guide member 132, and the third gear 135 meshes with the second guide member 132. In a first operating mode, the first gear 133 rotates in the forward direction under the action of a first target force, so as to drive the second gear 134 and the third gear 135 to rotate synchronously, causing the first guide member 131 and the second guide member 132 to move towards each other. In a second operating mode, the first gear 133 rotates in the reverse direction under the action of a second target force opposite to the first target force, so as to drive the second gear 134 and the third gear 135 to rotate synchronously, causing the first guide member 131 and the second guide member 132 to move in opposite directions.

[0061] In other words, the first gear 133 is subjected to the first target force (such as... Figure 1 During the process of the first gear 133 rotating in the forward direction under a counterclockwise force, it simultaneously provides rotational force to the second gear 134 and the third gear 135. This allows the second gear 134 to move the first guide member 131 closer to the second guide member 132, while the third gear 135 can move the second guide member 132 closer to the first guide member 131, thereby reducing the distance between the first guide member 131 and the second guide member 132. Conversely, during the process of the first gear 133 rotating in the reverse direction under a second target force opposite to the first target force, it simultaneously provides rotational force to the second gear 134 and the third gear 135. This allows the second gear 134 to move the first guide member 131 away from the second guide member 132, while the third gear 135 can move the second guide member 132 away from the first guide member 131, thereby increasing the distance between the first guide member 131 and the second guide member 132.

[0062] In this embodiment, the heat conduction channel can be conveniently opened or closed by applying a first target force or a second target force to the first gear 133; and the first gear 133 and the first guide member 131 transmit force through the meshing action of the second gear 134, while the first gear 133 and the second guide member 132 transmit force through the meshing action of the third gear 135. Meshing makes the force transmission smoother, thus making the process of the second plate 12 moving away from or closer to the first plate 11 smoother.

[0063] In some embodiments, see Figures 1 to 4As shown, the first guide 131 comprises a first segment 1312 and a second segment 1313 which are perpendicular to each other, the first segment 1312 is provided with a first inclined surface 1311, and the second segment 1313 is provided with a first guide portion 1314 which is in sliding connection with the first plate body 11; the second guide 132 comprises a third segment 1322 and a fourth segment 1323 which are perpendicular to each other, the third segment 1322 is provided with a second inclined surface 1321, and the fourth segment 1323 is parallel to the second segment 1313 and is provided with a second guide portion 1324 which is in sliding connection with the first plate body 11; the first gear 133, the second gear 134 and the third gear 135 are located in a parallel space between the second segment 1313 and the fourth segment 1323, and the second gear 134 is in engagement with the second segment 1313, and the third gear 135 is in engagement with the fourth segment 1323; wherein, in the first use mode and the second use mode, the first guide portion 1314 slides along the first plate body 11 and the second guide portion 1324 slides along the first plate body 11.

[0064] For example, the first guide 131 comprises a first segment 1312 and a second segment 1313 which are perpendicular to each other, the second guide 132 comprises a third segment 1322 and a fourth segment 1323 which are perpendicular to each other, the first segment 1312 and the third segment 1322 are opposite to each other, the second segment 1313 and the fourth segment 1323 are parallel and correspond between the first segment 1312 and the third segment 1322, and a parallel space between the second segment 1313 and the fourth segment 1323 is provided with the first gear 133, the second gear 134 and the third gear 135, the second gear 134 is in engagement with the second segment 1313, and the third gear 135 is in engagement with the fourth segment 1323, so that, under the driving of the first gear 133, the second segment 1313 and the fourth segment 1323 move linearly in the respective length directions, and the first segment 1312 and the second segment 1313 move closer to or farther away from each other. At the same time, in the process of linear movement of the second segment 1313 and the fourth segment 1323 in the respective length directions, the sliding between the first guide portion 1314 on the second segment 1313 and the first plate body 11 and the sliding between the second guide portion 1324 on the fourth segment 1323 and the first plate body 11 limit the movement of the first guide 131 and the second guide 132, so that the movement of the first guide 131 and the second guide 132 is more stable.

The driving part can be a structure such as a motor that can provide a driving force, and the user can perform power-on or power-off operation on the driving part through physical buttons, touch screens, etc. connected with the driving part in signal, so as to rotate the first gear 133 in the case of power supply of the driving part, and stop the rotation of the first gear 133 in the case of power-off. The plate body structure 10 can be provided with the operation part 136, can be provided with the driving part, or can be provided with both the operation part 136 and the driving part.

[0069] In the embodiment, the plate body structure 10 can be provided with at least one of the operation part 136 and the driving part, and can have various setting modes.

[0070] In some embodiments, referring to Figs. 1-3, the movable mechanism 13 can include a limiting part 137 and an elastic part 138.
