Embodiment approach 1

[0023] Figure 1 ~ Figure 4 It is a drawing for explaining the vehicle-mounted camera of Embodiment 1, figure 1 It is a plan view showing the arrangement of main components such as the lens barrel and heat generating components on the circuit board constituting the vehicle-mounted camera ( figure 1 A) and a perspective view of the overall vehicle camera viewed from the upper left front ( figure 1 B), figure 2 It is a schematic cross-sectional view showing the state after the vehicle-mounted camera is mounted on the vehicle, including the optical axis and the vertical line.

[0024] also, image 3 It is an exploded view showing the state before the camera module and circuit board of the vehicle-mounted camera are installed in the case, Figure 4 It is a perspective view of the inner surface side of the upper case viewed from the lower side ( Figure 4 A) and using figure 1 B Partially cutaway perspective view showing the internal structure when the camera module and ...

Embodiment approach 2

[0065] In the first embodiment described above, there is no particular mention of the surface of the circuit board opposite to the mounting surface of the heat generating component. In this Embodiment 2, the example which provided the heat storage body in the area|region corresponding to the arrangement|positioning area|region of a heat generating component of the surface on the opposite side to the mounting surface of a heat generating component is demonstrated. Figure 7 It is a drawing for explaining the vehicle-mounted camera of the second embodiment, and shows the arrangement of components on the circuit board and is the same as that of the first embodiment. figure 1 The top view corresponding to A ( Figure 7 A) and a partially cutaway perspective view showing the internal structure of the state in which the circuit board is mounted in the upper casing seen from the lower side. In addition, in Figure 7 In B, for the sake of simplification, drawing of some ventilation...

Abstract

Comprising a lens barrel (1), a circuit board (5) on which an image processing circuit (41) for performing image processing for identifying a subject on the basis of an image signal is mounted, and a housing (7) having an air suction port (7vi) and an air discharge port (7vx) and housing the circuit board (5) so as to separate the image processing circuit (41) from the lens barrel (1) in the left-right direction. Between the inner surface (71fi) on the mounting surface side of the housing (7) and the circuit board (5), a ventilation path connecting the air suction port (7vi) and the air discharge port (7vx) is formed in a path that is separated from the lens barrel (1) and passes through a region in which the image processing circuit (41) is disposed.

Description

technical field [0001] This application relates to a vehicle camera. Background technique [0002] In recent years, in order to reduce the burden on drivers, Advanced Driver-Assistance Systems (ADAS: Advanced Driver-Assistance Systems) have been widely used, which can realize collision prevention, vehicle tracking control, lane keeping control, and the like. In ADAS, for example, using an on-board camera installed on the upper part of the windshield in front of the vehicle, objects such as vehicles in front, oncoming vehicles, people in crosswalks, lanes (lane information), traffic signs, road surface signs, traffic Traffic facilities information such as signal lights are identified. [0003] In order to accurately identify objects, traffic facility information, etc., it is necessary to align the phases of the signals aggregated for each of the multiple transmission lines output from the imaging element located behind the lens barrel and transmit them to the substrate mount...
