At the same time, the embodiment also provides cartesian coordinates X-Y-Z as a reference when describing the components. In addition, in order to facilitate the identification of the main characteristic components of the disclosure, unnecessary parts in the electronic device that are not related to the disclosure are omitted.

Please refer toFIG.1toFIG.3first. In the embodiment, an electronic device100is, for example, a notebook computer, which includes a body120and a foot pad module110. The body120has a bottom surface121. The foot pad module110includes a first foot pad111, at least one second foot pad112, and at least one rotating shaft113. Here, the embodiment is exemplified by one first foot pad111and respectively disposing two second foot pads112and two rotating shafts113at two opposite ends of the first foot pad111, but not limited thereto. The first foot pad111is fixed on the body120. The rotating shaft113connects the first foot pad111and the second foot pad112. The second foot pad112is rotated relative to the first foot pad111by the rotating shaft113, so that the foot pad module110can switch between a first state and a second state. For the detailed description of the states, please refer to the subsequent description of the related drawings. It should also be noted that in the embodiment, the bottom surface121of the body120is situated on the X-Y plane, so that the reference standard can be the same before and after the state of the foot pad module110is changed.

Please refer toFIG.1,FIG.3, andFIG.4at the same time, which show the first state of the foot pad module110. At this time, the body120is supported on a platform200by the first foot pad111and the second foot pad112at the same time. It should be noted here that the body120of the electronic device100of the embodiment is divided into a front side S1and a rear side S2opposite to each other, wherein for the notebook computer, the front side S1is also where the user is located, the foot pad module110is disposed on the rear side S2, and the electronic device100also includes a fixed foot pad140disposed on the front side S1. In other words, the electronic device100is supported on the platform200by the fixed foot pad140and the movable foot pad module110at the same time. In the first state, the first foot pad111is substantially coplanar with the second foot pad112, and the fixed foot pad140may or may not be coplanar with the first foot pad111and the second foot pad112. Here, the platform200is regarded as being situated on the X-Y plane or parallel to the X-Y plane.

Please refer toFIG.1andFIG.2again. It is worth mentioning that in the foot pad module110of the embodiment, the first foot pad111has a first appearance surface A1, and the second foot pad112has a second appearance surface A2and a hidden surface A4. Furthermore, the first foot pad111also has a first separation surface A5adjacent to the first appearance surface A1, and the second foot pad112also has a second separation surface A6adjacent to the second appearance surface A2, wherein the first separation surface A5is parallel to and facing the second separation surface A6and is located between the first appearance surface A1and the second appearance surface A2. In addition, the second foot pad112also has a contact surface A3, and the second appearance surface A2is located between the second separation surface A6and the contact surface A3. It should be noted that the appearance surface and the contact surface mean that the user can see the surface of the foot pad with naked eyes in the first state and the second state, the hidden surface means that the user cannot see the surface of the foot pad with naked eyes in the first state but can see the surface of the foot pad in the second state, and the separation surface means that the user cannot see the surface of the foot pad with naked eyes in both the first state and the second state.

In the first state as shown inFIG.1toFIG.4, the hidden surface A4of the foot pad module110faces the body120and is adjacent to the bottom surface121, and the contact surface A3is adjacent to the bottom surface121. The first appearance surface A1and the second appearance surface A2are coplanar with each other, so that the contours of the first foot pad111and the second foot pad112are consistent. Here, the first appearance surface A1and the second appearance surface A2are polyhedral cylinders formed by at least two surfaces, and substantially, the first appearance surface A1is three surfaces of the first foot pad111constantly exposed from the body120, and the second appearance surface A2is three surfaces of the second foot pad112exposed from the body120in the first state.

Please refer toFIG.2andFIG.3again. The following describes the rotation mechanism of the foot pad module110of the embodiment. As shown in the drawings, an axial direction113aof the rotating shaft113of the embodiment is inclined relative to the bottom surface121. Meanwhile, the first separation surface A5and the second separation surface A6are also inclined relative to the bottom surface121, and the axial direction113aof the rotating shaft113is substantially orthogonal to the first separation surface A5and the second separation surface A6. In this way, during the rotating process of the second foot pad112relative to the first foot pad111by the rotating shaft113, the first separation surface A5is constantly parallel to and facing the second separation surface A6.

Furthermore, the second foot pad112of the embodiment has a hollow column112aextending from the second separation surface A6and sleeved on the rotating shaft113. The second foot pad112also has a stopping rib112b, and the first foot pad111has a double-layer round hole111awith an opening formed on the first separation surface A5and a pair of stopping walls111bformed on the double-layer round hole111a. The rotating shaft113and the hollow column112aare rotatably assembled into the double-layer round hole111a, and the pair of stopping walls111bare located on a moving path of the stopping rib112b, wherein the pair of stopping walls111bmay be regarded as being located at two opposite ends of the pitch diameter of the double-layer round hole111a, so as to limit the rotatable angle range of the second foot pad112relative to the first foot pad111to be within 180 degrees.

Next, please refer toFIG.3. Here, the X-Z plane is used as a reference, each surface of the first foot pad111and the second foot pad112is orthographically projected onto the X-Z plane, and the explanation is as follows. In the foot pad module110in the first state of the embodiment, the projection (that is, the orthographic projection on the X-Z plane) of the second foot pad112has a first projection boundary A6P, a second projection boundary A4P, and a third projection boundary A2P, wherein the first projection boundary A6P and the second projection boundary A4P respectively correspond to the second separation surface A6and the hidden surface A4, and the third projection boundary A2P corresponds to the second appearance surface A2and is opposite to the second projection boundary A4P, that is, the hidden surface A4and one of the surfaces of the second appearance surface A2are the front and back surfaces of the second foot pad112. Here, the length of the second projection boundary A4P is 13 mm to 15 mm. There is a first included angle θ1between the first projection boundary A6P and the third projection boundary A2P, and the first included angle θ1is 45 degrees to 70 degrees, and preferably 45 degrees as shown in the drawing.

In addition, as shown inFIG.3, in the first state, the projection of the first foot pad111has a fourth projection boundary A3P, a sixth projection boundary ASP, and a seventh projection boundary A1P, wherein the fourth projection boundary A3P corresponds to the contact surface A3, the sixth projection boundary A5P corresponds to the first separation surface A5, and the seventh projection boundary A1P corresponds to the first appearance surface A1and is opposite to the bottom surface121(or the projection boundary of the orthographic projection of the bottom surface121on the X-Z plane). The third projection boundary A2P is coplanar with the seventh projection boundary A1P.

FIG.5is a schematic diagram of a temporary state of the electronic device ofFIG.1during a switching process.FIG.6is a schematic diagram of the electronic device ofFIG.1in a second state.FIG.7andFIG.8respectively illustrate the electronic device ofFIG.6from different viewing angles. Please refer toFIG.1,FIG.5, andFIG.6first. The rotating process of the second foot pad112relative to the first foot pad111can be clearly seen from the changes in the three drawings. In the embodiment, the body120also has a recess123located on the bottom surface121, and in the first state, the hidden surface A4of the second foot pad112faces the recess123. Then, as shown inFIG.5, a part of the second foot pad112during rotation is moved into the recess123, so that the recess123can provide a turning avoidance space required when rotating the second foot pad112.

Furthermore, after the second foot pad112is rotated by 180 degrees to switch from the first state to the second state shown inFIG.6toFIG.8, the second foot pad112protrudes from the first foot pad111, so that the body120is supported on the platform200by the second foot pad112, while also raising the first foot pad111to be above the platform200, so as to form a space SP between the body120and the platform200. At this time, the hidden surface A4is exposed from the body120and faces the first appearance surface A1, and the contact surface A3is relatively away from the bottom surface121. There is a second included angle θ2between the second projection boundary A4P and the seventh projection boundary A1P, and the second included angle θ2is 40 degrees to 90 degrees, and preferably 90 degrees as shown in the embodiment.

As shown inFIG.6orFIG.1, the body120of the electronic device100also has multiple openings122located on the bottom surface121, and the electronic device100also has a heat dissipation member (for example, a fan, not shown here) disposed in the body120. The foot pad module110in the second state undoubtedly provides a heat dissipation space for the heat dissipation component, so that heat dissipation air can be smoothly discharged from the body120through the openings122or cold air from the external environment can enter the body120through the openings122to enhance the heat dissipation effect. In addition, as shown inFIG.8, the foot pad module110in the second state is supported by the second foot pad112, so that the rear side S2of the body120is higher than the front side S1and is inclined relative to the platform200. At this time, the body120is only jointly supported by the second foot pad112and the fixed foot pad140, which is also conducive to improving the operating experience of the user. Referring to FIG.2,FIG.6, andFIG.7, in an embodiment of the disclosure, when the electronic device is in the second state, the two hidden surfaces A4of the two second foot pads112are opposite to each other.

Please refer toFIG.2andFIG.7at the same time. As mentioned above, the movable second foot pad112can effectively form the space SP to facilitate heat dissipation. Therefore, in the embodiment, the related characteristics of the second foot pad112are also exemplified as follows to obtain a better range.FIG.9provides an adjustment plan for dimensions related to a second foot pad. Please refer toFIG.9. An adjustment table as shown inFIG.9is further obtained by the dimension of the third projection boundary A2P of the second foot pad112and the first included angle θ1between the third projection boundary A2P and the first projection boundary A6P. In the foot pad module110in the second state, the body120is supported by the second foot pad112to form a relative height of 15 mm with the platform200as a preferred state, wherein the reason is that 15 mm can produce a better heat dissipation effect as shown. If the relative height is greater than 15 mm, the generated gain effect will be limited, and if the relative height is less than 15 mm, the heat dissipation effect will be significantly reduced. Therefore, in the case of using 15 mm as a target value for a dimension d1shown inFIG.3to be equal to 15 mm, the first included angle θ1is correspondingly adjusted to verify a dimension d2(that is, the relative height from the bottom surface121to the platform200) and a third included angle θ3formed when rotating to the second state (which is also equivalent to proving the second included angle θ2, which is substantially an interior angle on the same side as the third included angle θ3).

It can be seen fromFIG.9that the third included angle θ3obtained by Number1to Number6is 40 degrees to 90 degrees, and the dimension d2can all approach the target value of 15 mm. In contrast, the dimension d2for Number10and Number11is less than 15 mm, which does not meet the heat dissipation requirement of the embodiment, and although the dimension d2for Number7to Number9approaches the target value of 15 mm, the third included angle θ3is already an obtuse angle (100 degrees to 120 degrees). It can be seen fromFIG.7that once the third included angle θ3is an obtuse angle, the second foot pad112will be too close to the first foot pad111in the second state, which is not conducive to supporting the body120, that is, the preferred state of the third included angle θ3of the embodiment should be a right angle or an acute angle.

FIG.10AandFIG.10Bare simple schematic diagrams of an electronic device according to another embodiment of the disclosure. Please refer toFIG.10AandFIG.10Bat the same time. In the embodiment, the electronic device further includes a synchronization mechanism130, which includes a pair of universal joints131and a transmission member132. The transmission member132passes through the first foot pad111, and the universal joints131are respectively disposed at two opposite ends of the transmission member132. Each rotating shaft113is connected between one universal joint131and one second foot pad112. In this way, the second foot pads112located at the two opposite ends of the first foot pad111can synchronously rotate through the universal joints131and the transmission member132, that is, the user only needs to apply force to one of the second foot pads112to synchronously drive the other second foot pad112, so as to simplify the operation of the user.

In summary, in the embodiments of the disclosure, the foot pad module is disposed on the bottom surface of the body of the electronic device, wherein the first foot pad is fixed on the body, and the second foot pad is rotatably connected to the first foot pad through the rotating shaft, so that the second foot pad can rotate 180 degrees relative to the first foot pad to be switched between the first state and the second state. In the first state, the body is supported on the platform by the first foot pad and the second foot pad, and in the second state, the second foot pad protrudes from the first foot pad, so that the body is supported on the platform by the second foot pad.

Accordingly, through the movable configuration of the second foot pad and the first foot pad, the user can adjust the state of the foot pad module in response to requirements. In the second state, the second foot pad can deviate from the bottom surface and protrude from the first foot pad to further raise the body, so as to increase the space between the body and the platform. At the same time, in cooperation with the operation of the fan inside the body, the heat dissipation air can be smoothly discharged from the body or the cold air from the external environment can enter the body through the bottom surface of the body to achieve the heat dissipation effect. At the same time, the body raised by the second foot pad can therefore provide the user with a better operating experience.

In an embodiment, the electronic device further disposes the synchronization mechanism, such as including the universal joints and the transmission member, between the second foot pads, so that the user only needs to drive one of the second foot pads to smoothly and synchronously drive the remaining second foot pad, so as to improve the convenience for the user to drive the second foot pads.
