Detailed description of the invention
The situation of back mirror reflection automobile rear, side and the below of vehicle, makes driver can indirectly see the situation of these positions clearly.The invention provides a kind of vehicle mirrors and vehicle, by heater circuit being set in the housing of vehicle mirrors, when ambient temperature is during lower than default temperature threshold, thermal control switch conducting, be arranged at the heating plate of backsight glass back to backsight glass heats, can avoid backsight generation fog on glass, in the time that Vehicle Driving Cycle is in the low temperature environment such as night or winter, avoid driver to cause traffic accident because not seeing rear situation, improved drive safety.Utilize heating plate to heat vehicle mirrors, simple in structure, be convenient to install.
Below in conjunction with accompanying drawing, the detailed description of the invention of vehicle mirrors and vehicle is elaborated.
A kind of vehicle mirrors, vehicle can be car, lorry, bus etc., vehicle mirrors can be outside rear-view mirror or inside rear-view mirror.As shown in Figure 1, vehicle mirrors comprises housing 110, backsight glass 120 and heater circuit, and backsight glass 120 is arranged on housing 110, and heater circuit is arranged at housing 120 inside.Heater circuit comprises heating plate 130 and thermal control switch, heating plate 130 is connected with thermal control switch afterwards and electric power generating composition C/LOOP, heating plate 130 is arranged at backsight glass 120 back sides, thermal control switch is in ambient temperature conducting during lower than default temperature threshold, and temperature threshold can be adjusted according to actual conditions.
Heating plate 130 can be silica gel heating sheet, ceramic heating flake etc., and in the present embodiment, heating plate 130 is ceramic heating flake, simple in structure, heat up rapidly, temperature compensating is fast, also has advantages of long service life, can reduce productive costs.The quantity of heating plate 130 can be one, also can be multiple, therein in an embodiment, heating plate 130 comprises the first heating plate and the second heating plate that are arranged at respectively backsight glass 120 relative both sides, the back side, by backsight glass 120 is heated in backsight glass 120 relative both sides, the back side simultaneously, can make that backsight glass 120 heats more evenly, firing rate is faster.
Above-mentioned vehicle mirrors, heater circuit is set in housing, when ambient temperature is during lower than default temperature threshold, thermal control switch conducting, be arranged at the heating plate of backsight glass back to backsight glass heats, can avoid backsight generation fog on glass, in the time that Vehicle Driving Cycle is in the low temperature environment such as night or winter, avoid driver to cause traffic accident because not seeing rear situation, improved drive safety.Utilize heating plate to heat vehicle mirrors, simple in structure, be convenient to install.
Therein in an embodiment, backsight glass 120 can with housing 110 engagement connections, in the time that vehicle rocks or jolt, can prevent that backsight glass 120 from coming off from housing 110.In addition, housing 110 also can comprise the first housing and the second housing that are connected by screw, is convenient to take apart housing 110 and changes power supply BAT.
In an embodiment, thermal control switch can comprise switching valve and thermally dependent resistor therein, and the input end of switching valve connects positive source, and the mouth of switching valve is connected with power cathode by heating plate 130, is appreciated that heating plate 130 also can be connected to positive source.Thermally dependent resistor is connected between the control end and input end of switching valve, and the resistance of thermally dependent resistor reduces and increases with ambient temperature, and switching valve can be positive-negative-positive aerotron or P channel MOS tube.Also can directly replace switching valve and thermally dependent resistor with temperature-sensitive aerotron in other embodiments.
