Abstract
A cliff sensor and a self-moving device. The cliff sensor comprises an optical emitter and an optical receiver, an emission light path of the optical emitter being provided with a first convex lens, a partition plate being arranged between the optical emitter and the optical receiver, a portion on the first convex lens close to the partition plate being provided with a first total-reflection structure, the first total-reflection structure being used for totally reflecting first light rays, and the first light rays being part of light rays emitted by the optical emitter and, in the first convex lens, emitted to the partition plate.
Claims20
A cliff sensor, comprising:
- a light emitter and a light receiver, wherein
- a first convex lens is provided on a light emitting path of the light emitter, and a partition is provided between the light emitter and the light receiver;
- and
- a first total reflection structure is provided on a portion of the first convex lens close to the partition, and the first total reflection structure is configured to totally reflect first light, wherein the first light is a part of light emitted by the light emitter and directed to the partition in the first convex lens.
A self-moving device, comprising a body and a cliff sensor, wherein the cliff sensor is arranged at a bottom of the body;
- wherein the cliff sensor comprises:
- a light emitter and a light receiver, wherein
- a first convex lens is provided on a light emitting path of the light emitter, and a partition is provided between the light emitter and the light receiver;
- and
- a first total reflection structure is provided on a portion of the first convex lens close to the partition, and the first total reflection structure is configured to totally reflect first light, wherein the first light is a part of light emitted by the light emitter and directed to the partition in the first convex lens.
