Description
Technical field
The utility model belongs to the auto navigation technical field, more specifically relates to a kind of automatic heat radiation automobile navigation instrument.
Background technology
Current along with scientific-technical progress and economic development, more People more and more is pursued the friendship ability instrument that freely makes things convenient for trip, and automobile is one of the most frequently used vehicles of people, and flourishing day by day highway network makes various automobile navigation instruments more and more universal.But automobile navigation instrument is installed in the windshield place of vehicle front usually, possibly receive solar light irradiation for a long time; Temperature is very high, and the orthodox car navigating instrument does not have radiator structure mostly, like this; Be in the navigating instrument unstable properties under the high temperature for a long time, and reduce serviceable life, even there is the part automobile navigation instrument to be provided with simple electric fan; Because the electric fan continuous running produces heat, cause navigating instrument and electric fan temperature to raise, the performance of navigating instrument and the life-span of life-span and electric fan are produced harmful effect; And the electric fan continuous running also can reduce the serviceable life of electric fan, wastes energy.
The utility model content
In order to address the above problem, the purpose of the utility model is to provide a kind of automatic heat radiation automobile navigation instrument, through to temperature auto control, intermittently dispels the heat, and prolongs the serviceable life of battery and fan, and energy-conservation.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of automatic heat radiation automobile navigation instrument; Comprise the navigating instrument housing, be arranged at the anterior display screen of navigating instrument circuit board, navigating instrument housing in the navigating instrument housing and be arranged at the fan in the navigating instrument housing; Also comprise an automatic heat radiation structure, said automatic heat radiation structure is connected with fan.
More excellent, said automatic heat radiation structure comprises single-chip microcomputer, the temperature sensor that is connected with the signal input part of single-chip microcomputer, the signal output part of said single-chip microcomputer is connected with fan with relay respectively through the conversion contact pin.
More excellent, said temperature sensor adopts the high value thermistor.
After adopting technique scheme, its beneficial effect is: through the automatic heat radiation structure, the intermittent running of control fan realizes automatic heat radiation, and prolong the serviceable life of battery and fan, and energy-conservation.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
To shown in Figure 4, the utility model is provided with by protecgulum 11 and bonnet 12 like Fig. 1, and bonnet and protecgulum are formed the navigating instrument housing; Also have navigating instrument circuit board, the anterior display screen 6 of navigating instrument housing in the navigating instrument housing; Display screen 6 is the LED charactron and is arranged at fan in the navigating instrument housing and the automatic heat radiation structure that is built in the navigating instrument housing that the automatic heat radiation structure comprises single-chip microcomputer 1; Single-chip microcomputer 1 can adopt the P89LPC931 chip; The signal input part 101 of single-chip microcomputer 1 is connected with the temperature sensor 4 of high value thermistor, and the parameter input end of single-chip microcomputer 1 103 connects sets conversion contact pins 7, makes the single-chip microcomputer 1 can be in the mutual conversion between the ceiling temperature value of setting, lower-limit temperature value, the measurement state; Can setup parameter at the parameter setting input end 102 of single-chip microcomputer 1; Carry out parameter adjustment through increase key 3, minimizing key 2, contact pin 7 is connected with relay 9 respectively the signal output part 101 of single-chip microcomputer 1 through changing, fan 8 is electrically connected, and fan 8 is a small-sized fans.
At single-chip microcomputer parameter setting input end 102 capping temperature values, lower-limit temperature value and/or measurement state, temperature sensor 4 can be measured temperature automatically, and the temperature information of measuring is input to signal output part 104 from signal input part 101; Output terminal comprises signal output part 104, control signal output ends 105, shows signal output terminal 106, control indication end 107, and signal output part 106 can show and control signal output ends 104 and control indication end 107; Temperature value through lower limit indication end 108, the 110 pairs of settings in upper limit indication end 109 and power supply indication end is adjusted; When certain temperature of setting that temperature reaches setting of working as, temperature can show that on display screen 6 pilot lamp 5 is glittering; The switch 10 of relay 9 will be opened or close automatically simultaneously; 8 runnings of control fan perhaps stop, thereby reach the purpose of automatic control fan heat radiation, and fan is not worked when reaching set temperature value owing to temperature; Saved the loss of battery electric quantity like this; Prolonged the service time and the life-span of battery, fan is not because need continuous running and the minimizing of wearing and tearing yet, and prolong serviceable life.
Above-described only is the preferred implementation of a kind of automatic heat radiation automobile navigation instrument of the utility model; Should be understood that; For the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
