Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to a multifunction digital versatile disk (DVD) expansion playback device and, more particularly, to a device, which combines a portable DVD player and a fixing base having the functions of a peripheral together.  
       BACKGROUND OF THE INVENTION  
       [0002]     A common portable DVD player can perform read, playback or access of audio/video data. A car ceiling DVD player has the same functions and is fixed in a car, but can&#39;t be taken out for use.  
         [0003]     If a consumer wants to simultaneously have the functions of a portable DVD player and a car ceiling DVD player, he has to pay more money.  
         [0004]     Accordingly, if the functions of a portable DVD player and a car ceiling DVD player can be integrated together, the expense can be greatly reduced.  
       SUMMARY OF THE INVENTION  
       [0005]     One object of the present invention is to provide a multifunction DVD expansion playback device connected with the car electric power and a peripheral, whereby a portable DVD player can be combined in a car.  
         [0006]     Another object of the present invention is to provide a multifunction DVD expansion playback device, which is applicable indoors and outdoors.  
         [0007]     Yet another object of the present invention is to provide a multifunction DVD expansion playback device capable of lowering the cost.  
         [0008]     To achieve the above objects, the present invention provides a multifunction DVD expansion playback device, which combines a fixing base having the functions of a peripheral and a portable DVD player together.  
         [0009]     When the DVD player and the fixing base are combined together, signals of the peripheral are received from the DVD player. The DVD player can also be taken out from the fixing base.  
         [0010]     The above peripheral can be an assembly of amplitude modulator (AM), frequency modulation (FM) or car audio loudspeakers.  
         [0011]     The power of the above DVD player comes from the car electric power or an external direct current (DC) power.  
         [0012]     The above DVD player can be combined with the fixing base by means of embedding, slide grooves, rollers or slide tracks.  
         [0013]     The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0022]     As shown in  FIGS. 1, 2  and  6 , a multifunction DVD expansion playback device of the present invention comprises a fixing base  1  having functions of a peripheral and a portable DVD player  2 .  
         [0023]     The fixing base  1  is slightly L-shaped, and is disposed in a car. Several (three) barbs  11  and a power connection portion  13  of the car electric power  3  are disposed on the bottom face of the fixing base  1 . A cavity  12  is formed between the barbs  11 . A connection component  14  connected with the peripheral is disposed on a side face adjacent to the bottom face of the fixing base  1 . In this embodiment, the peripheral can be an assembly of car audio loudspeakers  4 , AM  5  and FM  6 .  
         [0024]     The DVD player  2  has a cover body  21  and a dock  22 , which are pivotally connected together. The cover body  21  has a display  211  and loudspeakers  212 . A connection port  23  connected with the connection component  14  of the fixing base  1  is disposed on a side face of the dock  22 . Three embedding grooves  24  and a set of connectors  25  are disposed on the dock  22 . A catch component  26  is disposed between the embedding grooves  24 . A control component  27  is disposed in front of the catch component  26 . The embedding grooves  24  correspond to the barbs  11  when the DVD player  2  and the fixing base  1  are engaged. The catch component  26  corresponds to the cavity  12 . The connectors  25  contact the power connection portion  13 . The connection port  23  connects the connection component  14 .  
         [0025]     When the DVD player  2  uses the embedding grooves  24  and the catch component  26  thereon to engage the barbs  11  and the cavity  12  of the fixing base  1 , the connection port  23  of the DVD player  2  is connected with the connection component  14  of the fixing base  1 , and the connectors  25  will contact the power connection portion  13  to let the power of the DVD player come from the car electric power  3 . Signals of the peripheral are received from the DVD player  2 .  
         [0026]     The DVD player  2  can be taken out from the fixing base  1  through manipulation of the control component  27  (moved rightwards). Afterwards, the DVD player  2  can be used separately through the power from a battery base (not shown).  
         [0027]     As shown in  FIG. 3 , the working power of the DVD player  2  of the present invention can also be acquired in another way. A connection point  28  is formed on a side face of the DVD player  2 . A power connection pole  15  is projectively disposed on a side face of the fixing base  1 . When the DVD player  2  uses the embedding grooves  24  and the catch component  26  thereon to engage the barbs  11  and the cavity  12  of the fixing base  1 , the connection port  23  of the DVD player  2  can be connected with the connection component  14  corresponding to the fixing base  1 , and the connection point  28  will contact the power connection pole  15  to let the power of the DVD player come from the car electric power  3 .  
         [0028]     The DVD player  2  can be taken out from the fixing base  1  through manipulation of the control component  27  (moved rightwards). Afterwards, the DVD player  2  can be used separately through the power from a battery base (not shown).  
         [0029]     As shown in  FIG. 4 , an accommodation room  16  is disposed in the bottom face of the fixing base  1 ′. Guide grooves  17  are formed at two sides of the fixing base  1  for insertion of a DVD player  2 ′. A catch component  18  is disposed at one side at front edge of each of the guide grooves  17 . A connection component  14 ′ connected with a peripheral and a power connection pole  15 ′ of the car electric power  3  are disposed on a side face adjacent to the guide grooves  17 ′ of the fixing base  1 ′. In this embodiment, the peripheral can be an assembly of loudspeakers  4 , AM  5  and FM  6 , as shown in  FIG. 7 .  
         [0030]     The DVD player  2 ′ has a cover body  21 ′ and a dock  22 ′, which are pivotally connected together. The cover body  21 ′ has a display  211 ′ and loudspeakers  212 ′. A connection port  23 ′ and a connection point  28 ′ are disposed on a side face of the dock  22 ′. Sliding projective portions  29  are formed at two sides adjacent to the connection port  23 ′. A locking hole  30  is disposed in front of each of the sliding projective portions  29 .  
         [0031]     When the DVD player  2 ′ uses the sliding projective portions  29 ′ and the locking holes  30  thereon to engage the guide grooves  17  and the catch components  18  of the fixing base  1 ′, the connection port  23 ′ can be connected with the connection component  14 ′ corresponding to the fixing base  1 ′. The connection point  28 ′ contacts the power connection pole  15 ′ to let the power of the DVD player  2 ′ come from the car electric power  3 . Signals of the peripheral are received from the DVD player  2 ′.  
         [0032]     The DVD player  2 ′ can be taken out from the fixing base  1 ′ through manipulation of the catch components  18 . Afterwards, the DVD player  2 ′ can be used separately through the power from a battery base (not shown).  
         [0033]     As shown in  FIG. 5 , the fixing base  1  is horizontally assembled (or hung) in a car. The power connection portion  13  (or the power connection pole  15 ,  15 ′) and the connection component  14  ( 14 ′) of the fixing base  1  ( 1 ′) are connected with the car electric power  3  and the peripheral, respectively. When the DVD player  2  and the fixing base  1  are assembled together, a user can select contents to be played through manipulation of the DVD player  2 .  
         [0034]     Moreover, a volume adjust component  201  and an earphone socket  202  are disposed on a side face of the dock  22  (or  22 ′) of the DVD player  2  (or  2 ′).  
         [0035]     As shown in  FIG. 8 , when the present invention is applied indoors (e.g., in an apartment), the power of the fixing base  1 ′ having the functions of a peripheral directly comes from a DC power outputted by an adaptor  7 . When the DVD player  2 ′ and the fixing base  1 ′ are assembled together, a user can select contents to be played through manipulation of the DVD player  2 ′.  
         [0036]     Besides, in addition to embedding and slots, the DVD player  2  (or  2 ′) of the present invention can also be combined with the fixing base  1  (or  1 ′) by means of rollers, slide tracks or in a hydraulic way.  
         [0037]     To sum up, the present invention has the following characteristics: 
        1. A portable DVD player and a fixing base having the functions of a peripheral can be combined together by means of slots or embedding mechanism to form a multifunction DVD player.     2. For consumers, there is another choice, and the purchase cost can be lowered.     3. The present invention can be applied indoors and outdoors.
