Description
Technical field
The present invention relates to automatic navigator, particularly relate to the better automatic navigator of a kind of thermal diffusivity.
Background technology
Automatic navigator, that one can help user vehicle accurately to locate current line truck position, and calculate stroke according to set destination, the driving auxiliary equipment of destination is walked to by the multimedia mode such as map denotation, voice message steer motor user, along with the progress of science, the favor of the accurate navigator that rolls into one of location, navigation, the amusement function extremely people of collection, becomes the basic equipment on car gradually.
Existing vehicle mounted guidance is formed primarily of the Navigation Control circuit board in panel, cabinet and cabinet, and described panel comprises face frame, display screen and multimedia control circuit board; In traditional assembling process, panel and cabinet are all be connected together by the panel rack of platy structure.Due to the small volume of automatic navigator, thus, the radiating effect of current automatic navigator is all poor, especially in navigation and the process that simultaneously works of radio reception, the heat that navigator produces is larger, the heat that Navigation Control circuit board and multimedia control circuit board are sent is formed and superposes, and easily affects the stability of navigator work.Although what have dispelling the heat to cabinet by arranging fin, greatly can increase again volume and the cost of navigator like this, and affecting the applicability of navigator.
Summary of the invention
For prior art above shortcomings, the object of the invention is to the problem how solving existing automatic navigator radiating effect difference, there is provided a kind of thermal diffusivity better automatic navigator, can effective improving radiating effect, thus make the job stability of navigator better.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is such: the better automatic navigator of a kind of thermal diffusivity, comprise panel, cabinet and be located at the Navigation Control circuit board in cabinet, described panel comprises face frame, display screen and multimedia control circuit board, and this cabinet comprises top board, base plate, backboard and biside plate; It is characterized in that: described backboard is heating panel, backboard is vertically provided with some thermal troughs, and described thermal trough is recessed to form by backboard Inside To Outside, and forms the heat radiation fin of protuberance in the outside of backboard; Between Navigation Control circuit board and panel, be vertically provided with a thermal insulation board, the top board of described thermal insulation board and cabinet, base plate and biside plate are fixedly connected with; Top board between thermal insulation board and panel and base plate are equipped with some louvres, and described louvre is bar shaped, and is uniformly distributed along the Width of cabinet.
Further, the surrounding of described dividing plate has flanging, and described flanging is fixedly connected with cabinet by screw.
Further, described backboard is aluminium sheet, copper coin or aluminium alloy plate.
Compared with prior art, tool of the present invention has the following advantages:
1, structure is simple, by arranging thermal trough on backboard, thus effectively can increase the area of dissipation of backboard, thus improves radiating effect, and can effectively reduce costs.
2, between Navigation Control circuit board and panel, thermal insulation board is set, thus the heat that Navigation Control circuit board and multimedia control circuit board can be avoided to produce superposes mutually, and the heat that multimedia control circuit board produces can be dispelled the heat by louvre, thus better can ensure the stability of the work of navigator, and excessively can not increase the volume of navigator, to ensure the applicability of navigator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is rearview of the present invention.
In figure: 1-panel, 2-cabinet, 3-heat radiation fin, 4-thermal insulation board, 5-louvre.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment: see Fig. 1, Fig. 2, the better automatic navigator of a kind of thermal diffusivity, the Navigation Control circuit board comprising panel 1, cabinet 2 and be located in cabinet 2, described panel 1 comprises face frame, display screen and multimedia control circuit board, and this cabinet 2 comprises top board, base plate, backboard and biside plate.
Described backboard is heating panel, and during making, described backboard is aluminium sheet, copper coin or aluminium alloy plate, and radiating effect is better.Backboard is vertically provided with some thermal troughs, and described thermal trough is recessed to form by backboard Inside To Outside, and forms the heat radiation fin 3 of protuberance in the outside of backboard.By arranging thermal trough on backboard, thus effectively can increase the area of dissipation of backboard, thus improve radiating effect, and can effectively reduce costs.
Between Navigation Control circuit board and panel 1, be vertically provided with a thermal insulation board 4, the top board of described thermal insulation board 4 and cabinet 2, base plate and biside plate are fixedly connected with; The surrounding of described dividing plate has flanging, and described flanging is fixedly connected with cabinet 2 by screw.Thermal insulation board 4 is set between Navigation Control circuit board and panel 1, thus the heat that Navigation Control circuit board and multimedia control circuit board can be avoided to produce superposes mutually.Top board between thermal insulation board 4 and panel 1 and base plate are equipped with some louvres 5, and described louvre 5 in bar shaped, and is uniformly distributed along the Width of cabinet 2.Like this, the heat that multimedia control circuit board produces can be dispelled the heat by louvre 5, thus better can ensure the stability of the work of navigator, and excessively can not increase the volume of navigator, to ensure the applicability of navigator.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
