Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The invention relates to a portable electronic device and more particularly to an electronic device with an adjustable underlay-pad. 
         [0003]    2. Description of the Prior Art 
         [0004]    Please refer to  FIG. 1  and  FIG. 2 .  FIG. 1  is an exterior view of a laptop  1  in prior art.  FIG. 2  is an exterior view with another view angle of the laptop  1  in  FIG. 1 . Traditional laptop  1  includes a casing  10  and a display panel  12  pivotally connected to the casing  10 . The display panel  12  can be rotated relative to the casing, such that the user can open or close the display panel  12 . 
         [0005]    As shown in  FIG. 2 , the bottom  100  of the casing  10  thereon has four underlay-pads  14 . The underlay-pads  14  have an anti-skidding function, so the laptop  1  can be placed stably on the table or other plane. However, the underlay-pad  14  of laptop  1  generally is fixed, that means the distance between the bottom of the laptop  1  and the table can not be adjusted at will. Moreover, the use sometimes uses the laptop  1  at a place without a table, so the user puts the laptop  1  on their legs. When the user sits down, the extension direction of the legs usually is not parallel to the horizontal plane. Therefore, the laptop  1  placed on the legs will tend to tilt and can not be placed stably, and it is not convenient for the user. 
         [0006]    Therefore, the invention provides a portable electronic device with an adjustable underlay-pad to solve the aforementioned problems. 
       SUMMARY OF THE INVENTION 
       [0007]    A scope of the invention is to provide a portable electronic device with an adjustable underlay-pad, so that when the user places the portable electronic device, the portable electronic device can be adjusted to a suitable position. 
         [0008]    According to an embodiment, the portable electronic device of the invention includes a casing, a first support, and a second support. The casing includes a bottom and a recess formed on the bottom. The recess includes a first side-portion, a second side-portion opposite to the first side-portion, a third side-portion adjacent to the first side-portion, and a fourth side-portion opposite to the third side-portion. The first support includes a first end and a second end, and the second support includes a third end and a fourth end. 
         [0009]    In this embodiment, the first end of the first support can be slidably connected to the first side-portion and the second side-portion, and the first side-portion is adjacent to the third side-portion. The third end of the second support is pivotally connected to the second end of the first support. The fourth end of the second support is pivotally connected to the first side-portion and the second side-portion, and the fourth end is near to the fourth side-portion. 
         [0010]    When the first end of the first support slides along the first side-portion and the second side-portion, the first support drives the second support to rotate relative to the casing. When the portable electronic device is placed on the legs of the user or other planes, the pivotal connection between the first support and the second support can support the portable electronic device at a suitable height, so that the user can easily operate the portable electronic device.

         [0026]    As shown in  FIG. 4  and  FIG. 5 , the casing  30  includes a bottom  300  and recesses  302   a  and  302   b  formed on the bottom  300 . The structure of the recess  302   a  is the same as the recess  302   b , so the following description only focuses on the recess  302   a.    
         [0027]    Please refer to  FIG. 6  and  FIG. 7 .  FIG. 6  is an exterior view of the casing  30  in  FIG. 5 .  FIG. 7  is an exterior view with another view angle of the casing  30  in  FIG. 6 . The recess  302   a  includes a first side-portion  3020 , a second side-portion  3022  opposite to the first side-portion  3 , a third side-portion  3024  adjacent to the first side-portion  3020 , and a fourth side-portion  3026  opposite to the third side-portion  3024 . Additionally, the first side-portion  3020  includes a first slide groove  30200  and a first pivot hole  30202 , and the second side-portion  3022  includes a second slide groove  30220  and a second pivot hole  30222 . 
         [0028]    Please refer to  FIG. 4  and  FIG. 5 . The portable electronic device  3  of the invention further includes two first supports  34   a  and  34   b , and two second supports  36   a  and  36   b . The structure of the first support  34   a  is the same as the first support  34   b , and the structure of the second support  36   a  is the same as the second support  36   b . To simplify the description, the following description focuses on the first support  34   a  and the second support  36   a.    
         [0029]    Please refer to  FIG. 8 .  FIG. 8  is an enlarged view of the first support  34   a  and the second support  36   a  in  FIG. 5 . The support  34   a  includes a first end E 1  and the second end E 2 , and the second support  36   a  includes a third end E 3  and a fourth end E 4 . The first end E 1  of the first support  34   a  includes a first slide shaft  340  and a second slide shaft  342 . The fourth end E 4  of the second support  36   a  includes a first pivot shaft  360  and a second pivot shaft  362 . Besides, the first support  34   a  includes an underlay-pad  344 . The underlay-pad  344  is disposed between the first end E 1  and the second end E 2 , for example, the underlay-pad  344  can be disposed near to the second end E 2 . The underlay-pad  344  has a function of anti-skidding, such that the portable electronic device  3  can be stably placed on the legs of the user or other plane. 
         [0030]    Please refer to  FIG. 6 ,  FIG. 7  and  FIG. 8 . When the first support  34   a , the second support  36   a , and the casing  30  are assembled together, the third end E 3  of the second support  36   a  is pivotally connected to the second end E 2  of the first support  34   a  first of all. Afterward, the first slide shaft  340  of the first support  34   a  is disposed on the first slide groove  30200  of the casing  30 , and the second slide shaft  342  of the first support  34   a  is disposed on the second slide groove  30220  of the casing  30 . Then, the first pivot shaft  360  of the second support  36   a  is pivotally connected to the first pivot hole  30202  of the casing  30 , and the second pivot shaft  362  of the second support  36   a  is pivotally connected to the second pivot hole  30222  of the casing  30 . After the assembling is completed, the first end E 1  of the first support  34   a  is near to the third side-portion  3024  of the recess  302   a , and the fourth end E 4  of the second support  36   a  is near to the fourth side-portion  3026  of the recess  302   a.    
         [0031]    Accordingly, the first end E 1  of the first support  34   a  can be operated by the user to slide along the first side-portion  3020  and the second side-portion  3022  of the recess  302   a , to drive the second support  36   a  to rotate relative to the casing  30 . In this embodiment, the first support  34   a  drives the second support  36   a  to rotate relative to the casing  30 , so the second end E 2  of the first support  34   a  and the third end E 3  of the second support  36   a  protrude from the plane  30   a  of the casing  30 . The portable electronic device can be adjusted by the aforesaid protrusion structure. 
         [0032]    It should be noticed that an operation part  36  is formed on a pivotal connection between the second end E 2  of the first support  34   a  and the third end E 3  of the second support  36   a , and the operation part  35  can be operated by the user. Please refer to  FIG. 9  and  FIG. 10 .  FIG. 9  is a schematic diagram illustrating the first support  34   a  and the second support  36   a  at a closed status.  FIG. 10  is a schematic diagram illustrating the first support  34   a  and the second support  36   a  at an opened status. In this embodiment, the user can operate the operation part  35  to switch the closed status (shown in  FIG. 9 ) of the first support  34   a  and the second support  36   a  to the opened status (shown in  FIG. 10 ). 
         [0033]    In other words, when the user puts the portable electronic device  3  on the plane, the first support  34   a  and the second support  36   a  are at a closed status. When the user puts the portable electronic device  3  on their legs or other inclined plane, the operation part  35  can be pulled by hand, so the first support  34   a  can slide along the first side-portion  3020  and the second side-portion  3022  of the recess  302   a . Furthermore, the second support  36   a  is driven to rotate relative to the casing  30 , and then the first support  34   a  and the second support  36   a  are at opened status shown in  FIG. 10 . Accordingly, the user can adjust the distance between the underlay-pad  344  and the bottom  300  of the casing  30  at will. 
         [0034]    Please refer to  FIG. 6 ,  FIG. 7 , and  FIG. 8 . The first slide groove  30200  has a fifth end E 5  and the sixth end E 6 . The fifth end E 5  has a first clip part N 1 , and the sixth end E 6  has a second clip part N 2 . The second slide groove  30220  has a seventh end E 7  and the eighth end E 8 . The seventh end E 7  has a third clip part N 3 , and the eighth end E 8  has a fourth clip part N 4 . When the first support  34   a  and the second support  36   a  are at a closed status (shown in  FIG. 9 ), the first clip part N 1  and the third clip part N 3  are respectively used for limiting the movement of the first slide shaft  340  and the second slide shaft  342  of the first support  34   a . Therefore, the first support  34   a  and the second support  36   a  will be accommodated in the recess  302   a.    
         [0035]    When the first support  34   a  and the second support  36   a  are at an opened status (shown in  FIG. 10 ), the second clip part N 2  and the fourth clip part N 4  are respectively used for limiting the movement of the first slide shaft  340  and the second slide shaft  342  of the first support  34   a . Therefore, the first support  34   a  and the second support  36   a  pivotally connected to the first support  34   a  both keep a support status, and furthermore the portable electronic device  3  can be placed stably on the legs of the user or other surface. In this embodiment, the first support  34   a  will drive the second support  36   a  to rotate an angle relative to the casing. For example, the angle is larger than or equal to 90 degrees, so the second support  36   a  leans again the fourth side-portion  3026  of the recess  302   a . The first slide shaft  340  and the second slide shaft  342  of the first support  34   a  are fixed in the recess  302   a  by the second clip part N 2  and the fourth clip part N 4 . Therefore, the first support  34   a  and the second support  36   a  constitute a support structure of the portable electronic device  3 , so the portable electronic device  3  can be placed stably on the legs of the user or other plane. 
         [0036]    Please refer to  FIG. 11  and  FIG. 12 .  FIG. 11  is an exterior view of a casing  50  according to another embodiment of the invention.  FIG. 12  is an exterior view of the first supports  34   a  and  34   b  and the second supports  36   a  and  36   b  respectively disposed on the casing  50  in  FIG. 11 . The main difference between the aforesaid casing  30  and the casing  50  is that the recess  302   a  has three block parts  3028  shown in  FIG. 11 , and the recess  302   b  also has three block parts  3029  shown in  FIG. 11 . When the first supports  34   a  and  34   b  slide respectively relative to the recesses  302   a  and  302   b , the block parts  3028  and  3029  are respectively used for limiting the movement of the first supports  34   a  and  34   b . In this embodiment, the user can adjust the distance between the underlay-pad and the bottom of the electronic device by the block parts  3028  and  3029 , and the opened status shown in  FIG. 12  is only one of all possible statuses possible. The amount and the positions of the block parts  3028  and  3029  should be noted that they can be designed at will. If the amount of the block parts  3028  and  3029  are larger, and the positions of the block parts  3028  and  3029  are arranged more tightly, the distance between the underlay-pad and the bottom of the electronic device can be more finely adjusted. 
         [0037]    When the user puts the portable electronic device on their legs or other plane, the user can utilize the movable support of the invention to adjust the difference between the underlay-pad and the bottom of the electronic device, that is, the height of the portable electronic device is adjustable. Therefore, the portable electronic device of the invention can be adjusted to be suitable for operation of the user. Additionally, the portable electronic device of the invention further includes block parts, so the height of the portable electronic device can be finely adjusted, and it is more convenient for the user. 
         [0038]    With the example and explanations above, the features and spirits of the invention will be hopefully well described. Those skilled in the art will readily observe that numerous modifications and alterations of the device may be made while retaining the teaching of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
