Description:
FIELD OF THE INVENTION 
       [0001]    The present invention generally relates to a device holder apparatus for vehicle, and more specifically to an attachment apparatus with antenna, applicable to various device holders for vehicles. 
       BACKGROUND OF THE INVENTION 
       [0002]    A wide range of portable electronic devices are becoming a part of the modern daily life for most people, such as mobile phones, audiovisual player, PDA, GPS, digital TV, and so on. These electronic devices are also used in vehicles. However, as most of the electronic devices are not standard options to the majority of the vehicles, the driver usually needs an additional holder to hold the electronic devices in place so that the use of these electronic devices will not interfere with the driving. One popular design of the holder uses a supportive rod and a clipping holding part. Based on the attachment method, the bottom of the supportive rod can further divided into two categories, suction disc and glue. The supportive rod uses the internal joint structure for position adjustment. The clipping holding part is for clipping and holding the electronic device. The engagement between the supportive rod and the clipping holding part uses a detachable buckle mechanism that can be easily disengaged and re-engaged. So that when different electronic devices are used, only different clipping holding parts are removed and replaced, instead of changing the entire device holder. 
         [0003]    Many of the electronic devices used in the vehicle come with an antenna set for providing better reception for wireless communication devices, such as GPS, DTV, and so on. However, the design of the convention holder with sucker usually does not provide additional holder to the antenna set of these wireless communication devices. Therefore, some antenna set is attached to the ceiling by a magnet. Alternatively, additional conductive wire is used to connect the antenna set placed on the dash board close to the windshield. With the limited space in the vehicle, the additional wires for antenna set is not only in convenient, but also dangerous to interfere with the driving. In addition, when different electronic devices are held by the holder, different antenna sets must be used. The removal and replacement of the antenna set is an additional inconvenience. 
         [0004]    Therefore, it is important to devise an attachment apparatus with an antenna that is applicable to various device holders for vehicles so that the user can easily install the attachment apparatus to the device holder to hold the devices that uses antenna. 
       SUMMARY OF THE INVENTION 
       [0005]    The primary object of the present invention is to provide a replaceable attachment apparatus with antenna, for using with the device holders for vehicle. When the driver uses the holder to hold the wireless communication device, the present invention can be used to accommodate the wireless communication device, and the antenna of the present invention can be used for signal reception to eliminate the scattered additional wires. As the attachment apparatus with antenna of the present invention is not of any specific standard, it is applicable to a wide range of device holders. 
         [0006]    Another object of the present invention is to provide an attachment apparatus that is visually esthetic and inexpensive to replace. The attachment apparatus is to be attached to the device holder so that when a wireless communication device is held in the holder, the wireless communication device is also connected to the attachment apparatus without conventional problem of scattered wires. In addition, the antenna of the present invention is also behind the device holder so that the antenna will not interfere the driving. As the attachment apparatus can be used with existing device holder, it is not necessary to replace the existing device holder. 
         [0007]    To achieve the above objects, the present invention provides an attachment apparatus with antenna, including a connection unit, a support unit and an antenna unit. The connection unit includes at least a first attachment part. The first attachment part can be attached to the device holder for vehicle. The support unit partially extends to the inside of the connection unit and is fastened there. The support unit is bendable. The antenna unit is connected to the other end of the support unit. The antenna unit includes a connection wire for connecting the electronic device. The attachment apparatus with antenna is applicable to a wide range of device holders for vehicle. 
         [0008]    When the support unit of the present invention is retractable, the connection unit further includes an accommodating trench and a locking buckle unit. The accommodating trench is formed inside the connection unit, and the support unit is partially placed inside the accommodating trench. The locking buckle unit is located in the connection unit so that the locking buckle can lock the support unit in place inside the accommodating trench.

         [0018]    Although support unit  2  is connected and fastened to connection unit  1 , support unit  2  can be divided into two types, retractable and non-retractable. The non-retractable support unit  2  is a support unit that can only adjust the antenna position by bending. A retractable support unit  2  is a support unit that can retract or extend for a small distance to change the position of the antenna. The embodiment of the present invention shows the retractable support unit, but the present invention is not limited to this embodiment. 
         [0019]    As shown in  FIGS. 1&amp;2 , connection unit  1  includes a first attachment part  11 , a second attachment part  12 , an accommodating trench  13 , and a locking buckle  14 . The shape of connection unit  1  is rectangle, with a large first area  111  and a large second area  121  facing each other. First attachment part  11  and second attachment part  12  are on first area  111  and second area  121  respectively. The shapes of first attachment part  11  and second attachment part  12  are designed to match the object to be attached to. In this embodiment, first attachment part  11  is a concave locking trench, and second attachment part  12  is a protruding T-shape locking block. As shown in  FIG. 3 , The interior of connection unit  1  further includes a long accommodating trench  13 . Accommodating trench  13  penetrates through connection unit  1  entirely, and is for accommodating support unit  2  when retracted. The cross-section of accommodating trench is not circular, but a square, so as to prevent support unit  2  from rotating. Support unit  2  can move along the axis of accommodating trench  13  to change the length of support unit  2  extending outside of connection unit  1 . A locking buckle unit  14  is included inside connection unit  1  at the location near to the middle point of accommodating trench  13  for locking support unit  2  in place. Locking buckle unit  14  further includes a button  141  and a resilient element  142 . One end of button  141  is a block  143  with the middle coupled to the inner wall of connection unit  1 . Resilient element  142  is a button spring and is engaged to the coupling location of button  141  to provide button  141  the automatic recovery resilience after pressed. Block  143  has a shape matching the shape of support unit  2  to prevent support unit  2  from accidental retraction or extension. 
         [0020]    Support unit  2  is bendable long column, and can be made of material such as metal coated with a plastic layer. Support unit  2  includes a plurality of non-circular ribs  21  arranged in a ring on the outside. In the present embodiment, ribs  21  are square-shaped to match the shape of accommodating trench  13 . A small concave ring trench  22  is between two neighboring ribs  21  for block  143  of locking buckle unit  14  to block and lock. 
         [0021]    Antenna unit  3  is connected to the other end of support unit  2 . Antenna unit  3  includes a hidden antenna loop or circuit, designed to match the wireless communication device. Antenna unit  3  further includes a connection wire  31  for connecting the wireless communication device. In the present embodiment, the front end of connection wire  31  is inside antenna unit  3 , the middle segment is buried inside support unit  2 , and the rear end extends from the bottom of support unit  2  for connecting to wireless communication device. 
         [0022]    As shown in  FIG. 4 , to adjust the position of antenna unit  3 , the user must first pull support unit  2  to the desired length, and then bend the support unit  2  to desired angle so that antenna unit  3  is adjusted to the best position for reception of signals. When used with device holder for vehicle, the antenna of the present invention can be adjusted by adjusting support unit  2 . 
         [0023]      FIG. 5  shows a schematic view of the present invention in actual application. As shown in  FIG. 5 , the present invention is used with a device holder  4  with a suction disc. The top of suction holder  4  is an attachment plate  41  to connect a clipping holding part  5 . When in use of the present invention, the user must first remove clipping holding part  5 . Because connection unit  1  of the present invention includes a first attachment part  11  and second attachment part  12 , the shape of first attachment part  11  of the present embodiment matches the shape of the back of clipping holding part  5 , and the shape of second attachment  12  of the present embodiment matches the shape of block  411  of attachment plate  41 , connection unit  1  uses first attachment part  11  to engage attachment plate  41  of suction holder  4 , and uses second attachment part  12  to engage clipping holding part  5 . Therefore, when a wireless communication device, such as GPS, is held by clipping holding part  5 , connection wire  31  of antenna unit  3  of the present invention can be connected to GPS. Finally, suction holder  4  can be attached to windshield, and support unit  2  is adjusted to allow the best reception of signal for antenna unit  3 . 
         [0024]      FIG. 6  shows a second embodiment of the present invention. In the second embodiment, the structure of antenna unit  3  is different. As shown in  FIG. 6 , antenna unit  3  is connected to one end of support unit  2 . Retractable antenna  32  is pulled out and rotated for adjustment. Therefore, antenna unit  3  of the present invention is not limited to specific planar antenna. 
         [0025]    In summary, the attachment apparatus with antenna of the present invention uses the shape of connection unit to match conventional device holder for vehicle to widen the application of the present invention. The adjustability of the support unit and antenna unit allows the user to find the best reception of the signals without the disadvantages of the conventional device holder.
