Embodiment Construction

[0034] One embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Here, the in-vehicle camera 50 will be described as an example of the vehicle-outside information acquisition means. Therefore, the information acquisition path of the information acquisition means outside the vehicle becomes the field of view 5 of the on-vehicle camera 50 .

[0035] figure 1 is a schematic perspective view showing the heating device 100 according to one embodiment of the present invention. in addition, figure 2 is shown to have figure 1 A schematic cross-sectional view of the vehicle-mounted camera device 1 of the heating device 100 is shown in a state of being attached to the window glass W inside the vehicle.

[0036] The heating device 100 according to the present embodiment is a constituent part of the vehicle-mounted camera device 1, such as figure 1 As shown, there is a shield 10 and a heating element 20. The shield 10 has ...

Abstract

An aim of the invention is to provide a heating device that is for an outside-vehicle information acquisition means, has high heating efficiency, can be made thin, and has a high degree of freedom inthe layout of a heater. [Solution] A heating device 100 heats a window glass portion Wa located on an information acquisition path of an outside-vehicle information acquisition means 50 that is disposed inside the vehicle and that acquires information from outside the vehicle, the heating device comprising: a hood 10 provided inside the vehicle, below the information acquisition path 5 of the outside-vehicle information acquisition means 50; and a heating element 20 provided on the surface or inside of the hood 10 and having a PTC heater layer 21.

Description

technical field [0001] The present invention relates to a heating device for heating a window glass portion located on an information acquisition path of an exterior information acquisition means arranged inside a vehicle to acquire information on the outside of the vehicle. Background technique [0002] An on-vehicle camera device is an example of an outside-vehicle information acquisition device that is arranged inside a vehicle and acquires information outside the vehicle. As such an on-vehicle camera device, there is known a type that includes a heating device that heats a window glass portion in the field of view of the on-vehicle camera to prevent the window glass portion from being blurred by dew condensation or the like (see Patent Document 1). This heating device is, for example, a device that includes a shield ("shield" in Patent Document 1) and a heating element attached to the shield, and heats the window glass portion using thermal energy released from the heati...
