Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to an electronic device with a deflection device; more particularly, the present invention relates to an electronic device with a deflection device, wherein the deflection device is used for coordinating with interface cards of different sizes. 
         [0003]    2. Description of the Related Art 
         [0004]    As technology develops, computer systems are also increasingly powerful, but at the same time, the heat generated by a computer system also increases. In a computer system, in addition to the central processor, the memory or the hard disk drive, the interface card installed on the motherboard can also generate heat during high-speed operation. In order to smoothly dissipate the heat generated by the interface card, a wind scoop is provided in the prior art to directly guide the airflow generated by the fan device to the interface card. But different interface cards are of different heights; therefore, a wind scoop with a rigid shape cannot meet the requirements of interface cards of different heights. If the manufacturer redesigns the size of the wind scoop according to different interface cards, the design and production costs will be prohibitively high. 
         [0005]    Therefore, there is a need to provide a deflection device to solve the disadvantage of the prior art. 
       SUMMARY OF THE INVENTION 
       [0006]    It is an object of the present invention to provide a deflection device for coordinating with the interface cards of different sizes. 
         [0007]    It is another object of the present invention to provide an electronic device with the abovementioned deflection device. 
         [0008]    To achieve the abovementioned object, the deflection device of the present invention is located in the electronic device for guiding an airflow generated by a fan device to at least one electronic component of the electronic device. The deflection device includes a first fixed part and a plurality of strip structures. The first fixed part is used for fixing the deflection device in a suitable position within the electronic device. One end of each strip structure is connected to the first fixed part, and at least one part of any two adjacent strip structures is not connected to each other, allowing each strip structure to undergo compression deformation independently such that it forms a first shape when not pressed or a second shape when pressed; when the deflection device is fixed in a suitable position of the electronic device and close to the electronic component, the shape of the at least one strip structure is changed from the first shape to the second shape due to contacting the electronic component for guiding the airflow to the electronic component. 
         [0009]    The electronic device of the present invention includes a fan device, at least one electronic component, and a deflection device. The fan device is used for generating the airflow. The deflection device is used for guiding the airflow of the fan device to the at least one electronic component. The deflection device includes a first fixed part and a plurality of strip structures. The first fixed part is used for fastening the deflection device in a suitable position within the electronic device. One end of each strip structure is connected to the first fixed part, and at least one part of any two adjacent strip structures is not connected to each other, allowing each strip structure to undergo compression deformation independently such that it forms a first shape when not compressed or a second shape when compressed. When the deflection device is fixed in a suitable position of the electronic device and close to the electronic component, the shape of the at least one strip structure is changed from the first shape to the second shape due to contacting the electronic component for guiding the airflow to the electronic component.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0017]    These and other objects and advantages of the present invention will become apparent from the following description of the accompanying drawings, which disclose several embodiments of the present invention. It is to be understood that the drawings are to be used for purposes of illustration only, and not as a definition of the invention. 
         [0018]    Please refer to  FIG. 1 , which illustrates a schematic drawing of the deflection device in the first embodiment of the present invention. The deflection device of the present invention is applied to an electronic device, such as a desktop computer, but the present invention is not limited to that application. 
         [0019]    In the first embodiment of the present invention, the deflection device  10   a  includes a first fixed part  21 , a second fixed part  22 , and a plurality of strip structures  30   a.  The first fixed part  21  and the second fixed part  22  are fastened to the internal structure in the electronic device  1 , such as fastened to the wall of the case  2  (as shown in  FIG. 2 ) or to the wind scoop  70  (as shown in  FIG. 4A ). The plurality of strip structures  30   a  can be made of deformable and elastically restored sheet-like material with softness and toughness, such as a polycarbonate film, but the present invention is not limited to that design. The two ends of each strip structure  30   a  are respectively connected to the first fixed part  21  and the second fixed part  22 , and any two adjacent strip structures  30   a  are not connected to each other, allowing each strip structure  30   a  to undergo compression deformation independently In the first embodiment, the plurality of strip structures  30   a  can be divided into a first section  31 , a second section  32 , and a third section  33  according to the shape. One end of the first section  31  is connected to the first fixed part  21 . One end of the second section  32  is connected to the second fixed part  22 . The two ends of the third section  33  are respectively connected to an end of the first section  31  and an end of the second section  32 . The third section  33  is located between the first section  31  and the second section  32 . 
         [0020]    The first section  31  faces an incoming direction of the airflow F, and a wind angle θ is formed between the first section  31  and the first fixed part  21  along a direction which faces the incoming direction of the airflow F. In the present embodiment, the wind angle θ is larger than 90°, allowing the first section  31  to be a tilted backwards shape relative to the first fixed part  31 . In addition, if the strip structure  30   a  is made of a soft material, such as a polycarbonate film, then a metal spring structure  40  can be additionally fixed on the first section  31  and the first fixed part  21  along the direction which faces the incoming direction of the airflow F to increase the support force and the resilience of the first section  31  and the first fixed part  21 . However, in another embodiment, if the strip structure  30   a  is made of another material with great flexibility and strong support force, the metal spring structure  40  may not be additionally added in the present invention. In addition, in the present embodiment, the second section  31  is substantially parallel to the first section, and the first fixed part  21  and the second fixed part  22  are located on a same virtual plane, allowing the first fixed part  21 , the second fixed part  22 , the first section  31 , the second section  32 , and the third section  33  together to form a structure similar to a parallelogram. 
         [0021]    Please refer to  FIG. 2 , which illustrates a schematic drawing of the deflection device applied to the computer device in the first embodiment of the present invention. 
         [0022]    The deflection device  10   a  of the present invention is applied to the electronic device  1 . The electronic device  1  can be a computer system, such as a desktop computer, but the present invention is not limited to that application. The electronic device  1  includes a case  2 , a fan device  50 , an electronic component, and other circuit elements (not shown in the figure). In the first embodiment of the present invention, the electronic component is an interface card  60 , but the present invention is not limited to the interface card  60 . The deflection device  10   a , the fan device  50 , and the interface card  60  are all located in the case  2 , and the first fixed part  21  and the second fixed part  22  of the deflection device  10   a  are fastened to the top of the case  2 . Therefore, the first section  31 , the second section  32 , the third section  33 , and the case  2  together form a parallelogram. The fan device  50  is used for generating airflow to dissipate the heat generated by the interface card  60 . Via the shape formed by the deflection device  10   a  and the case  2  of the electronic device  1 , the incoming direction of the airflow (Inter Flow) F generated by the fan device  50  will be changed to form a guided flow F′ that is guided to the at least one interface card  60 , such that the heat from the interface card  60  can be dissipated efficiently 
         [0023]    Please refer to  FIG. 3 , which illustrates a schematic drawing of the deflection device applied to a different interface card in the first embodiment of the present invention. 
         [0024]    In the plurality of strip structures  30   a,  the width of each strip structure  30   a  corresponds to the width of the interface card  60 . Since each strip structure  30   a  can undergo compression deformation independently, the shape of each strip structure  30   a  can be flexibly changed according to the assembly height of the coordinating interface card  60 . As shown in  FIG. 3 , when the specific interface card  61  is installed in the electronic device  1 , the third section  33  of the corresponding strip structure  301  of the plurality of strip structures  30   a  will be contacted and pushed upward by the specific interface card  61  such that the shape of the strip structure  301  will be changed based on the height of the specific interface card  61  when installed to form the second shape; i.e., the height of the third section  33  of the corresponding strip structure  301  will be changed, but the change will not affect the shape or height of other strip structures  30   a.  The specific interface card  61  can be an interface card with a large size, but if the specific interface card  61  is an interface card with a small size, the shape of the corresponding strip structure  301  can also be adjusted. Therefore, the shape of the strip structure  30   a  can be changed automatically when the strip structure  30   a  is in contact with interface cards  60  of different specifications. In addition, when the specific interface card  61  is removed from the electronic device  1 , the corresponding strip structure  301  can return to its original first shape due to the structure of the strip structure  301  or the elasticity of the metal spring structure  40 . 
         [0025]    According to the abovementioned description, each strip structure  30   a  of the deflection device  10   a  can coordinate with the height of the corresponding electronic component installed under the strip structure  30   a  to correspondingly and elastically change in shape; also, the strip structure  30   a  may lie flat against the top of the case  2  so as not to occupy the internal space of the case  2 . It is to be known that the second fixed part  22  of the deflection device  10   a  does not need to be fastened to the case  2 , nor does the deflection device  10   a  need to have the second fixed part  22 ; due to the feature of the material of the strip structure  30   a,  the desired deformation and elastic restoring force can be achieved. 
         [0026]    Please refer to  FIG. 4A-4B , which illustrate schematic drawings of the deflection device applied to a computer device in the second embodiment of the present invention. 
         [0027]    The deflection device  10   a  of the present invention is not limited to being fastened to the case  2  of the electronic device  1 . In the second embodiment of the present invention, the electronic device  1  may have a wind scoop  70 . The wind scoop  70  is located on the inlet of the fan device  50  so that the airflow generated by the fan device  50  can be more efficiently guided to the interface card  60 . The deflection device  10   a  is connected to the inside of the wind scoop  70  and located on the interface card  60 . The shape of the strip structure  30   a  of the deflection device  10   a  can also be changed according to different configurations of the interface cards  60 . Since the shape of the deflection device  10   a  in the second embodiment is the same as the shape in the first embodiment, and the working method is the same, there is no need for further description. 
         [0028]    Please refer to  FIG. 5 , which illustrates a lateral view of the deflection device in the third embodiment of the present invention. 
         [0029]    In the third embodiment of the present invention, the deflection device  10   b  also includes the first fixed part  21 , the second fixed part  22 , and the plurality of strip structures  30   b.  The plurality of strip structures  30   b  also include a first section  31 , a second section  32 , and a third section  33 , but the first section  31 , the second section  32 , the third section  33 , and a virtual plane where the first fixed part  21  and the second fixed part  22  are located form only a quadrilateral (such as a keystone) and do not form a parallelogram as in the first embodiment. Due to the shape, the deflection device  10   b  can still guide the airflow to different interface cards  60 . 
         [0030]    Please refer to  FIG. 6 , which illustrates a lateral view of the deflection device in the fourth embodiment of the present invention. 
         [0031]    In the fourth embodiment of the present invention, the length of the third section  33  of each strip structure  30   c  of the deflection device  10   c,  for contacting the corresponding interface card  60 , is reduced to form a transition structure that connects to the first section  31  and the second section  32 , allowing a specific angle between the first section  31  and the second section  32  to be less than 180°. Thus, the first section  31 , the second section  32 , the third section  33 , and the virtual plane where the first fixed part  21  and the second fixed part  22  are located together form a triangle. Due to the shape, the deflection device  10   c  still can guide the airflow to different interface cards  60 , and the area of contact between the strip structure  30   c  and the interface card  60  is reduced. 
         [0032]    Please refer to  FIG. 7 , which illustrates a lateral view of the deflection device in the fifth embodiment of the present invention. 
         [0033]    The difference between the fifth embodiment and the abovementioned embodiment is that the third section  33  is an arc-shaped structure. Via the deflection device  10   d,  the airflow still can be guided to different interface cards  60 . However, it will be obvious to people who have general knowledge of the art of the present invention that the third section  33  can also be other shapes, as long as the shape can achieve the object of the present invention: to contact to the interface card  60  and to connect to the first section  31  and the second section  32 . 
         [0034]    With the application of the abovementioned devices from deflection device  10   a  to  10   d,  the airflow generated by the fan device  50  can be guided to an interface card  60  of any size. 
         [0035]    It is noted that the above-mentioned embodiments are only for illustration. It is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents. Therefore, it will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention.
