PROBLEM TO BE SOLVED: To provide an on-vehicle camera rain drop removal device which can realize an on-vehicle camera rain drop removal device with a simple configuration and at an inexpensive price by reducing development cost.SOLUTION: An imaging lens 2b installed on a front face of an on-vehicle camera 2a is covered by a cover 3. A water absorbing material 4 which is held between the imaging lens 2b and the back face of the cover 3 is installed on the back face of the cover 3 facing the front face of the on-vehicle camera 2a. An on-vehicle camera rain drop removal device 1 removes rain drops attached to the imaging lens 2b of the on-vehicle camera 2a by absorbing them by the water absorbing material 4. A top plate 5 is installed on the top face of the on-vehicle camera 2a, with the top plate 5 being rotatably connected to the cover 3 by a hinge 6. The other end of the top plate 5 is connected to an arm 7b of an extensible unit 7a. The arm 7b extends and contracts in a direction along the top face of the on-vehicle camera 2a. When gear change operation to a back gear of the vehicle is detected by a sensor, the extensible unit 7a contracts the arm 7b until the top plate 5 and the cover 3 form a predetermined angle.SELECTED DRAWING: Figure 1
【課題】 簡単な構成で車載カメラ雨滴除去装置を実現でき、開発コストを抑制して安価に車載カメラ雨滴除去装置を提供する。【解決手段】 車載カメラ2aの前面に設けられた撮影レンズ2bはカバー3によって覆われる。車載カメラ2aの前面に対向するカバー3の裏面には、撮影レンズ2bとカバー3の裏面との間に挟まれる吸水材4が設けられる。車載カメラ雨滴除去装置1は、車載カメラ2aの撮影レンズ2bに付着した雨滴を吸水材4で吸い取って除去する。車載カメラ2aの天面には天板5が設けられ、天板5は蝶番6によってカバー3と回動自在に連結される。天板5の他端は伸縮器7aの腕7bに連結される。腕7bは車載カメラ2aの天面に沿った方向に伸縮する。車両のバックギヤへのギヤチェンジ操作がセンサによって検知されると、伸縮器7aは、天板5とカバー3とが所定角度を成すまで腕7bを縮める。【選択図】 図1
