With scientific and technological development, automobile enters daily life.When trip is to slightly remote destination, people are usual
Select self-driving trip.Automatic navigator can be positioned to vehicle by built-in gps system, and prompts people according to the map
Go to the best route of destination from departure place.When being warm, if car is parked in open parking ground by people, and
Get off go shopping or play when, automatic navigator is exposed to the sun by the sun, and temperature can quickly raise, and this generates one
Problem, the part electronic component being exposed to the sun within lower automatic navigator in the sun is easily damaged in hot environment, after a time
After people return on car, reopen be likely to be encountered during automatic navigator navigator cannot normally-open or after opening no
The situation of method normal work.
In order to solve the above problems, the invention provides a kind of vehicular navigator based on rotating mechanism.
This device is identical with traditional automatic navigator, also possess have housing, navigator and with navigator internal electron
The display screen that element is connected.Distinguish with traditional automatic navigator, first, the housing of this device is opened upwards for one
The housing of mouth, housing is cuboid or cube, and the inside of housing is cavity structure, is fixed with baffle plate on the bottom surface of housing,
The inner space of housing has been divided into two parts by baffle plate, i.e. the first Room and second Room, and inwall in the first chamber is provided with
Gripper shoe；Secondly, the upper surface of the top surface of gripper shoe, the top surface of baffle plate and housing is located at same level height, so arranges

The meaning joined is that size matches, i.e. rotating shaft can be freely rotatable in bearing groove, and shaft parallel in baffle plate, that is, defines two
The relative position of bearing groove, rotating shaft runs through rotor plate, i.e. rotor plate and rotating shaft is relatively fixed so that both can be simultaneously around axle
Hold groove to rotate.
By said structure, when people are in driving procedure, rotor plate are placed on baffle plate and gripper shoe, lead
Towards user, user can recognize routing information by display screen to display screen on boat instrument, under irradiating in burning sun,
In car or opened air-conditioning or opened vehicle window, even if so sun direct irradiation navigator, but the ambient temperature of in-car is not
Height, be also not result in navigator cannot normal work, meanwhile, automobile be motion, will not be all exposed to the sun by the sun at any time；But
It is that, when car is rested in open parking ground by people, automobile is static, being exposed to the sun of the sun can lead to the ambient temperature liter of in-car
Height, navigator is by directly roasting solarization simultaneously.In order to avoid navigator damages, rotary motion plate, at this time there are both situations, first,
Navigator cannot be put in the second Room of housing, and at this time navigator is contacted with the top surface of second Room, and rotor plate has overturn
Come, serve the effect blocking sunlight, decrease the sunlight being directly exposed to the sun on navigator；Second, navigator can put into
In the second Room of housing, at this moment navigator faces that face contact baffle plate of people when driving, and rotor plate blocks second Room
Opening, the effect of block sunlight is better.
In sum, this device passes through rotating mechanism so that when storing cycle is under burning sun, can rotary motion plate, make
Navigator can be contacted with baffle plate inside second Room with second Room upper surface or put into, meanwhile, rotor plate can hinder
Keep off the sunlight on navigator that is directly exposed to the sun, it is to avoid what navigator was rapidly heated and led in the case that sunlight is directly exposed to the sun leads
Boat instrument internal electronic element damages, people return to navigator when being again turned on navigator on car and occur cannot normally starting or opening
After dynamic cannot normal work situation.
When car is parked on open air parking place, rotor plate can reduce or avoid sunlight to be radiated on navigator completely,
The programming rate making navigator substantially slows down.But, because automobile integrally exposes under irradiation by sunlight and in-car is in and puts out
The state of fire, then in-car temperature can gradually rise with the time parked in the sun, even if navigator is not straight
Connect irradiation, after parking considerable time, in-car high temperature is it is also possible that lead to the electronic component within navigator to damage.
In order to solve the above problems, cooling fan is provided with the side wall of the first Room, the air outlet of described cooling fan is just to baffle plate, baffle plate
On be provided with some through holes parallel to horizontal plane, described through hole all connects the first Room and second Room.By said structure, work as car
When parking, adjustment swivel plate first so that navigator is contacted with second Room top surface or enters inside second Room, Ran Houkai
Open cooling fan, wind is blowed to second Room from the first Room by through hole by cooling fan, the wind entering second Room afterwards is contacted with navigator,
The air flow in accelerating navigation instrument face, can be effectively reduced the temperature of navigator, thus avoiding the high temperature of in-car to navigation
Instrument and its impact of internal electronic element.In sum, cooling fan allows air to circulate, and enters from the first outdoor first
Enter the first interior, then second Room is entered by through hole, finally discharge from the opening of second Room, enter back in the first Room.Above-mentioned
Circulation can speed up the air flow on navigator surface, and the air of quick flowing can be taken away partial heat on navigator, reach
Reduce the purpose of navigator temperature, be effectively protected the electronic component of navigator and its inside.
The direction that the diameter of through hole is set to along the first Room to second Room is gradually reduced.It has been arranged such three advantages,
First, because the through-hole diameter positioned at the first Room side is maximum, enables to more air and enter in through hole, air will not
In the first indoor formation vortex, pile up in the first chamber, the speed ultimately resulting in air circulation declines, and cooling effect is low；Second,
Through-hole diameter is gradually reduced, and the air flowing through through hole is extruded acceleration, and the air velocity entering in second Room increases, and air can
Flow through navigator surface at faster speed so that the heat of navigator scatters and disappears faster；3rd, the diameter of through hole is gradually reduced also
The air themperature flowing fast through through hole can be made to obtain a certain degree of reduction, principle is breathed out with mouth similar to people and told with mouth
Gas, after changing nozzle type, the air of exhalation is cold and hot differs.Further, since car is in flame-out state when stopping, so cooling
Fan needs to provide electric energy by battery.But, traditional battery is with certain risk and not ring under the high temperature conditions
Protect.In order to solve this problem, thin film solar cell is provided with the upper surface of gripper shoe, in-car much can now

It is arranged on the System of Rotating about Fixed Axis in the first ceiling face, after vehicle parking, when needing to put into navigator in second Room, rotary stopper
Plate, releases limit function.
Further, along the direction on baffle plate bottom to top, the distance between described through hole is first gradually reduced and gradually increases
Greatly.Will be close to baffle center via design more intensive, away from baffle center via design more loose.Because cold
But the wind speed on the cross section parallel with baffle plate of fan blowout is not identical everywhere, and is proximate to the speed at center faster,
Due to rubbing with the first chamber interior walls, its speed is relatively slow, by lead to the hole site on baffle plate for deep air
Improve, enable to air and more swimmingly flow to second Room from the first Room, accelerate the circulation rate of air, improve cooling effect
Really.
Further, a diameter of 1.2 centimetres of through hole minimum, through hole maximum gauge is the 1.5 ~ 2.5 of through hole minimum diameter
Times.When the diameter of through hole is less than 1.2 centimetres, the speed that air passes through baffle plate is slower, and air easily produces whirlpool in the first chamber
Stream, reduces the speed of air circulation flow, reduces cooling effect；Meanwhile, maximum gauge not should be greater than the 2.5 of minimum diameter
Times, otherwise because diameter change is too fast, the inwall of through hole can play, because angle problem, the effect hindering air circulation.
Further, the area of rotor plate largest face is more than the aperture area of second Room.By above-mentioned setting, in navigator
When being rotated into second Room, the upper surface of the upper surface of rotor plate and second Room and rotor plate covering second Room, this
Sample can further avoid sunlight to be irradiated on navigator.
Further, the area of navigator largest face is less than the aperture area of second Room.So setting makes rotary motion
