In the present invention, a thermoelectric element (4) is disposed between an on-board camera (1) and a windshield (2). The on-board camera (1) incorporates a temperature sensor (8). When the temperature of the on-board camera (1) is at least a threshold value, heat is caused to move from the on-board camera (1) to the windshield (2). When the temperature of the on-board camera (1) is less than the threshold value, a space formed by the on-board camera (1) and the windshield (2) is warmed using the self-generated heat of the thermoelectric element (4), and as a result, the formation of condensation on the windshield (2) is prevented.
本发明的车载摄像头装置中,将热电元件(4)设置在车载摄像头(1)和挡风玻璃(2)之间。车载摄像头(1)内置有温度传感器(8),当车载摄像头(1)的温度为阈值以上时,使热量从车载摄像头(1)传递到挡风玻璃(2),当车载摄像头(1)的温度小于上述阈值时,通过热电元件(4)的自行发热来加热由车载摄像头(1)和挡风玻璃(2)形成的空间,从而抑制挡风玻璃(2)的结露。
