Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of Invention 
         [0002]    The present invention relates to a pad of an electronic device. More particularly, the present invention relates to an electronic device with pad height adjustable, wherein the height of the foot protruding from the electronic device is changed to adjust different tilt angles of the electronic device. 
         [0003]    2. Related Art 
         [0004]    Along with the development and popularization of science and technology, each family has many electronic products, such as personal computer, notebook, city phone or internet protocol phone (IP phone), which make the life of the people more convenient. In order to put the electronic products stably on a table or on the ground, a plurality of feet is installed on the bottom of the electronic products to increase the friction against the table or the ground, so as to balance and stably support the electronic devices, thus preventing the electronic products from directly contacting the disposing plane or being damaged due to swing or collision. 
         [0005]    As for an IP phone, usually the conventional foot installed on the phone is simply formed by a plastic pad and a bolt, and a plurality of bolt holes is disposed in the bottom of the electronic device, so as to lock a corresponding number of bolt and plastic pad into the bolt holes, thus making the IP phone blocked up by a height. Alternatively, a supporting foot rest is installed on the bottom of the phone, so as to make the phone depart from the disposing plane for a fixed height. 
         [0006]    As the users dispose the IP phone at different positions, they have to adjust the height of the IP phone on practical demands. The method of adjusting the height of each foot is to rotate each plastic pad to the same height, such that the IP phone can lie stably, so it takes too much time to adjust each pad to the same height, which does not deviate from the efficiency requirement of the current society, but also causes unnecessary troubles to the user. Moreover, the manner of adopting a supporting foot rest may result in the increase of the fabricating cost and taking too much disposing space while the height thereof can not be adjusted, which causes many limits when the user selects the disposing position and is quite inconvenient. 
         [0007]    For the foot of the conventional art, the height thereof can not be quickly and precisely adjusted, so the user has to spend plenty of time adjusting the height and the tilt angle of the phone; for the supporting foot rest of the conventional art, the height thereof can not be changed and the disposing space is too large, which depart from the practical demands. 
       SUMMARY OF THE INVENTION 
       [0008]    In view of the above, the present invention provides an electronic device with pad height adjustable, so as to improve the disadvantages in the prior art that it takes too much time to adjust the height of the foot and a lot of disposing space is occupied. 
         [0009]    The electronic device with pad height adjustable disclosed by the present invention comprises a housing and a foot. The housing has an accommodating hole, and the foot has a body and at least one pad formed in the body. The body is disposed in the accommodating hole, and presses against the housing with the pad of the body, such that the body protrudes from the surface of the housing. 
         [0010]    The function of the present invention is that based on different occasions and requirements from the users, the users may find it convenient to quickly and precisely adjust the electronic device to have the required height and tilt angle, and greatly reduce the volume of the electronic device, so as to meet the market requirement of a light and thin electronic device. Moreover, in the electronic device with pad height adjustable, an elastomer is disposed and bonded to the foot, and an elastic force is provided to make the body of the foot press against the housing, so as to avoid the foot dropping to lose.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0026]    To acquire further understandings to the objectives, structure, features and functions of the present invention, they are illustrated in detail below with reference to the related embodiments. 
         [0027]    According to the electronic device with pad height adjustable disclosed by the present invention, the electronic device may be a notebook, telephone, projector or other portable electronic devices. In the following detailed description of the present invention, IP phone is adopted as an optimal embodiment of the present invention. However, the appended drawings are provided for reference and illustration, and are not used to limit the present invention. 
         [0028]      FIG. 1  is a schematic exploded view of the first embodiment of the present invention. As shown in the figure, an electronic device with pad height adjustable  100  comprises a housing  110 , a foot  120  and an elastomer  130 . The foot  120  has a body  121  and a plurality of pads  122  formed in the body  121 . An accommodating hole  111  is formed in the back of the housing  110  of the electronic device  100 , and a plurality of notches  112  is formed in the radial direction along the edge of the accommodating hole  111 . The body  121  is disposed in the accommodating hole  111 . When the body  121  is accommodated in the accommodating hole  111 , at least one of the pads  122  selectively presses against the housing  110 , and the rest of the pads  122  are respectively nested in each of the notches  112 , so as to make a part of the body  121  protrude from the surface of the housing  110 . Further, the thickness of each pad  122  is not equal to the thickness of the rest of the pads  122 , so when different pads  122  press against the housing  110 , the height of the body  121  protruding from the surface of the housing  110  is changed. 
         [0029]    As shown in  FIG. 2 , the elastomer  130  is disposed in the housing  110 , and bonded to one side of the housing  110  and the body  121 , for providing an elastic force to make the body  121  constantly press against the housing  110 , and to make the foot  120  fastened in the accommodating hole  111 , so as to avoid the dropping and losing of the foot  120 . The elastomer  130  of the present invention is a tension spring, for stably providing an elastic force for the foot  120 . Further, a side of the main body  121  facing the exterior of the housing  110  is a flat end face, for contacting a plane, such that when the electronic device  110  is disposed on the plane, the housing  110  is supported by the foot  120  to make the electronic device  100  form an included angle with the plane. The included angle is determined by the height of the body  121  of the foot  120  protruding from the housing  110 , and the height of the body  121  protruding from the surface of the housing  110  is determined by the thickness of the pad  122  pressing against the housing  110 . Therefore, through different pads  122  pressing against the housing  110 , the included angle formed between the electronic device  100  and the plane is determined by the pad  122  as the thickness of each pad  122  is different from the rest of the pads  122 . 
         [0030]    As shown in  FIG. 1  and  FIG. 3 , wherein the foot  120  has three groups of pads  122 , which are respectively disposed on one side of the body  121  facing the housing  110  with a fixed distance. Each group of the pads  122  are correspondingly disposed along the radial direction of the body  121 , so as to have a first position A 1 , a second position A 2  and a third position A 3 . The edge of the accommodating hole  111  has three groups of notches  112  corresponding to the positions A 1 , A 2  and A 3  of the three groups of pads  122  on the body  121 . It should be noted that the foot  120  of the first embodiment disclosed in the present invention is formed by three pads  122  of different thicknesses, and the number of the notches  112  along the edge of the accommodating hole  111  corresponds to that of the pads  122 . However, those skilled in the art may also change the design into more than three or less than three pads  122  of different thicknesses and a corresponding number of the notches  112 , such that the electronic device  100  may accordingly have different heights, and is not limited to the present embodiment. 
         [0031]    As shown in  FIGS. 4A ,  4 B and  4 C, the three pads  122  of the present invention are disposed at the positions A 1 , A 2  and A 3  of the body  121 , and the heights blocked up thereby are corresponding to a first height H 1 , a second height H 2  and a third height H 3 . 
         [0032]    Therefore, according to different requirements, the user adopts the pad  122  of the required height to press against the housing  110 , such that the electronic device  100  meets the practical demand of the user on height. In the present embodiment, the relation of the H 1 , H 2  and H 3  is H 3 &gt;H 2 &gt;H 1 , so when the pad  122  at the third position A 3  presses against the housing  110 , the rest of the pads  122  at A 1  and A 2  may be blocked up and depart from the surface of the housing  110 . However, when the pad  122  at the first position A 1  presses against the housing  110 , in order to avoid the heights H 1  and H 2  corresponding to A 2  and A 3  interfering with A 1 , the positions A 2  and A 3  can be nested in the notches  112 , so as to make the pads  122  at A 2  and A 3  embedded into the accommodating hole  111 , such that A 1  is not interfered due to the height difference. Of course, all the pads  122  can be nested in the notches  112 , such that the body  121  is completely embedded into the accommodating hole  111  instead of protruding from the housing  110 . 
         [0033]      FIG. 5  is a schematic exploded view of the second embodiment of the present invention. It is shown in the figure that the electronic device with pad height adjustable  100  comprises a housing  110 , a foot  120  and an elastomer  130 . The foot  120  has a body  121  and a pad  122  formed in the body  121 . An accommodating hole  111  is formed in the back of the housing  110  of the electronic device  100 , and a plurality of notches  112  is formed in the radial direction along the edge of the accommodating hole  111 . The body  121  is disposed in the accommodating hole  111 . When the body  121  is accommodated in the accommodating hole  111 , the pad  122  selectively presses against a notch  112  of the accommodating hole  111 , so as to make a part of the body  121  protrude from the surface of the housing  110 . Further, the thickness of each notch  112  is not equal to the thickness of the rest of the notches  112 . Therefore, when the pad  122  presses against different notches  112 , the height of the body  121  protruding from the surface of the housing  110  is changed. 
         [0034]    As shown in  FIG. 6 , the elastomer  130  is disposed in the housing  110 , and bonded to one side of the housing  110  and the body  121 , for providing an elastic force to make the body  121  constantly press against the housing  110 , and to make the foot  120  fastened in the accommodating hole  111 , so as to avoid the dropping and losing of the foot  120 . The elastomer  130  of the present invention is a tension spring, for stably providing an elastic force for the foot  120 . Further, one side of the main body  121  facing the exterior of the housing  110  is a flat end face, for contacting a plane, such that when the electronic device  110  is disposed on the plane, the housing  110  is supported by the foot  120  to make the electronic device  100  form an included angle with the plane. The included angle is determined by the height of the body  121  of the foot  120  protruding from the housing  110 , and the height of the body  121  protruding from the surface of the housing  110  is determined by the thickness of the notch  112  of the accommodating hole  111 . Therefore, through the pad  122  pressing against the notches  112  of different thicknesses, the included angle of the electronic device  100  with the plane is determined by the notches  112  as the thickness of each notch  112  is different from the rest of the notches  112 . 
         [0035]    As shown in  FIG. 5  and  FIG. 7 , the accommodating hole  111  has three groups of notches  112  respectively disposed along the edge of the accommodating hole  111  by a fixed distance. Each group of the notches  112  is correspondingly disposed in the radial direction of the accommodating hole  111 , thus obtaining a first position A 1 , a second position A 2  and a third position A 3 . It should be noted that the accommodating hole  111  of the second embodiment disclosed in the present invention has three notches  112  of different thicknesses. However, those skilled in the art can also change the design to more than three or less than three notches  112  of different thicknesses, such that the electronic device  100  accordingly has different heights, and is not limited to the present embodiment. 
         [0036]    As shown in  FIGS. 8A ,  8 B and  8 C, the pad  122  of the present invention presses against the positions A 1 , A 2  and A 3  of the three groups of notches  112 , and the heights blocked up thereby are corresponding to a first height H 1 , a second height H 2  and a third height H 3 . Therefore, according to different requirements, the user makes the pad  122  press against the notches  112  of the required height, such that the electronic device  100  meets the practical demand of the user on height. In the present embodiment, the relation of the H 1 , H 2  and H 3  is H 3 &gt;H 2 &gt;H 1 , so when the pad  122  presses against the notch  112  at the third position A 3 , the rest of the notches  112  at A 1  and A 2  are in a state of open. 
         [0037]    Compared with the conventional art, the electronic device with pad height adjustable disclosed by the present invention can quickly and precisely adjusts the electronic device to the height and the tilt angle required by the user, and greatly reduces the volume of the electronic device. 
         [0038]    The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
