The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of simple in structure, simplifies the vehicle-mounted audio host of production and assembly operation.
The purpose of this utility model is achieved through the following technical solutions:
a kind of vehicle-mounted audio host, described vehicle-mounted audio host comprises that top cover reaches and the basic vertical center that is connected of this top cover, it is characterized in that: described vehicle-mounted audio host also comprises heat radiator, four angular zones of described heat radiator are provided with the installation base of projection, be formed with the boss mounting hole on described installation base, described center is formed with the heat radiator fixed orifice relative with described boss mounting hole, the installation base of four angular zones of described heat radiator is fitted by web member on the heat radiator fixed orifice that is mounted on center, form between heat radiator and center a hollow separated region is arranged.Heat radiator and center adopt four angular zones to fit fixing and the middle hollow that forms is separated, can effectively reduce the heat conduction or be radiated in main frame by the hollow isolating construction, its radiating effect can satisfy the power requirement of DVD, make whole vehicle-mounted audio host can save radiator fan, reduced cost.
Preferably, described center is three one-tenth fence shapes and integrated " U " type structure.By the main framework of integrated " U " type structure center as main frame, the main frame component parts reduces, and during the main frame assembling, assembling procedure reduces relatively, makes the main frame assembling simpler, has improved production efficiency.
Concrete, be provided with a vehicle carried stereo inner works in described vehicle-mounted audio host, be formed with mounting hole on described movement, be formed with the movement fixed orifice relative with described mounting hole on described top cover.The movement of said structure need not movement fore-stock, movement after-poppet fixedly the time, and only needs by mounting hole, the movement fixed orifice of screw and setting, it directly to be fixed on top cover.Movement fore-stock and movement after-poppet had both been saved, fixing movement fore-stock, the movement after-poppet assembling procedure to the movement of twice when reduce producing again.
Described top cover is provided with the semi open model boss, and described movement fixed orifice arranges on described semi open model boss.
As another improvement of the present utility model, described center comprises integrated left side board, right side board and rear side board, and described rear side board is provided with a perforate platform that stretches out along the vertical bending to the inside of rear side board.Along the rear side board perforate platform of vertical bending to the inside, be easy to the components and parts that on perforate platform fixed placement need to increase expanded function one of the rear side board of center processing.
The utility model has the following advantages and beneficial effect compared to existing technology:
By the main framework of " U " type center as main frame, heat radiator and " U " type center adopt four angular zones to fit fixing and the middle hollow that forms is separated, and make whole vehicle-mounted audio host can save radiator fan, have reduced cost; Simultaneously, movement need not movement fore-stock, movement after-poppet fixedly the time, and only needs directly to be fixed on it on top cover by mounting hole, the movement fixed orifice of screw and setting, simplified assembling procedure, make the main frame assembling simpler, improved production efficiency, reduced the holistic cost of vehicle audio.
