  • Patent number: 11237029
    Abstract: A sensor hood (21) includes a bottom surface-forming section (26) that forms a flat bottom surface (26a) facing a detection space (K1). When seen from a height direction (Z1) perpendicular to a surface width direction (X1) and a surface forward/rearward direction (Y1) of the bottom surface (26a), a split section (P1) between a fixed body (30) and a split body (40) divides the bottom surface (26a) into a first range (H1) including an optical axis (CL3) in the surface width direction (X1) and a second range (H2) that avoids the optical axis (CL3). The first range (H1) is disposed at the same height as the second range (H2) in the height direction (Z1) and disposed closer to the optical axis (CL3) than the second range (H2).

  • Patent number: 10800343
    Abstract: Provided is an onboard electronic device mounting structure that prevents rattling of the electronic device, and does not unduly limit the mounting space for other components. The mounting structure (1) secures a camera (2) to a window (W) of a vehicle via a mounting device (3). An engagement portion (14) provided in a front end side of the camera abuts against a base (8) of the mounting device, and a biased portion including a columnar member provided on a lateral side of the camera is supported by the base. A biasing member (18) of the base biases the biased portion against a supporting portion (17) of the base. The supporting portion is provided with two supporting surfaces (17a and 17b) which support the biased portion with two reaction forces each at an angle to the direction of the biasing force of the biasing member.
