utility model content:
The purpose of this utility model is exactly the deficiency that exists for prior art and provides a kind of and improve circuit board universal, reduces the vehicle-carrying DVD of manufacturing cost.
To achieve these goals, the technical solution adopted in the utility model is: vehicle-carrying DVD, it includes main frame, be arranged on the main circuit board in main frame, be arranged on the control panel of main frame front end, display screen is provided with in the middle part of control panel, the position that control panel is positioned at display screen both sides is respectively equipped with control button, control panel inside is provided with the display drive circuit plate being positioned at display screen rear, be separately positioned on two button circuit boards of the display drive circuit plate left and right sides, be split-type structural between two button circuit boards and display drive circuit plate, display drive circuit plate respectively with display screen, main circuit board signal connects, two button circuit boards are electrically connected with the control button of corresponding side respectively, two button circuit boards are electrically connected with display drive circuit plate respectively.
Described two button circuit boards are weldingly fixed on display drive circuit plate respectively by tin cream.
The position that each button circuit board is connected with display drive circuit plate is respectively equipped with the many stitch stretched out backward, stitch to be plugged on display drive circuit plate and to be welded and fixed by tin cream and display drive circuit plate, and button circuit board is electrically connected with display drive circuit plate by stitch.
Described display screen is touch LCD screen.
The utility model beneficial effect is: the vehicle-carrying DVD that the utility model provides, include main frame, be arranged on the main circuit board in main frame, be arranged on the control panel of main frame front end, display screen is provided with in the middle part of control panel, the position that control panel is positioned at display screen both sides is respectively equipped with control button, control panel inside is provided with the display drive circuit plate being positioned at display screen rear, be separately positioned on two button circuit boards of the display drive circuit plate left and right sides, be split-type structural between two button circuit boards and display drive circuit plate, display drive circuit plate respectively with display screen, main circuit board signal connects, two button circuit boards are electrically connected with the control button of corresponding side respectively, two button circuit boards are electrically connected with display drive circuit plate respectively, traditional control circuit board is divided into display drive circuit plate and two button circuit boards by the utility model, button circuit board has versatility, the control panel of different size specification all uses identical button circuit board, only be required to be the display drive circuit plate that the design of LED of different size specification is different, the control panel producing different size specification only need be equipped with corresponding display drive circuit plate, do not need to redesign whole control circuit board, reduce Control panel design cost and manufacturing cost.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is the syndeton schematic diagram between each circuit board of the utility model.
embodiment:
Below in conjunction with accompanying drawing, the utility model is further described, see shown in Fig. 1 ~ 3, the utility model includes main frame 1, be arranged on the main circuit board 2 in main frame 1, be arranged on the control panel 3 of main frame 1 front end, display screen 4 is provided with in the middle part of control panel 3, the position that control panel 3 is positioned at display screen 4 both sides is respectively equipped with control button 5, control panel 3 inside is provided with the display drive circuit plate 6 being positioned at display screen 4 rear, be separately positioned on two button circuit boards 7 of display drive circuit plate 6 left and right sides, be split-type structural between two button circuit boards 7 and display drive circuit plate 6, display drive circuit plate 6 respectively with display screen 4, main circuit board 2 signal connects, two button circuit boards 7 are electrically connected with the control button 5 of corresponding side respectively, two button circuit boards 7 are electrically connected with display drive circuit plate 6 respectively.
