Shielding structure for camera and mower
A shielding structure is disposed around a camera of a mower, in a front of a forward direction of the mower. The shielding structure includes a first shielding plate, a second shielding plate, and a third shielding plate. The shielding plates from a lens surface of the camera. The first shielding plate is disposed above the camera to shield sunlight from a top of the camera. The second and third shielding plates are disposed on two sides of the camera to shield sunlight from the two sides of the camera. The shielding plates may be formed unitarily or separately, and they may be removably and/or retractably attached to the mower. The shielding plates may be arranged so that the shielding structure flares outwardly in the downward direction.
1 . A lawn mowing device comprising:
a mower having a front and a back, the mower being a robotic mower drivable in a forward direction extending from the back toward the front;
a camera located at the front of the mower pointing in the forward direction;
a shielding structure disposed around the camera, the shielding structure including a first shielding plate, a second shielding plate, and a third shielding plate, the first shielding plate being located between the second shielding plate and the third shielding plate, the second shielding plate and the third shielding plate each extending distally from the first shielding plate outwardly inclined such that a distance between the second shielding plate and the third shielding plate closer to the first shielding plate is shorter than a distance between the second shielding plate and the third shielding plate further away from the first shielding plate;
the first shielding plate, the second shielding plate, and the third shielding plate each being configured as separate components, each being detachably connected to the mower by a clamping or sliding connection, and each protruding relative to a lens surface of the camera so as to define a shielding area to shield the lens surface;
the first shielding plate being disposed above the camera to shield sunlight from a top of the camera;
the second shielding plate and the third shielding plate being respectively disposed on opposite sides of the camera to shield sunlight from the opposite sides of the camera; and
the first shielding plate, the second shielding plate, and the third shielding plate being are retractable relative to the mower to adjust the shielding area.
2 . The device according to claim 1 , wherein a first angle is formed between the second shielding plate and the first shielding plate, the first angle being between 90° and 180°; and
a second angle is formed between the third shielding plate and the first shielding plate, the second angle being between 90° and 180°.
3 . The device according to claim 1 , wherein the second shielding plate and the third shielding plate include anti-slip strips.
