Self-propelled apparatus with an anti-drop system
First Claim
1. A self-propelled apparatus with an anti-drop system, comprising:
- a main body, including an aperture and at least one driving wheel located at a bottom portion of the main body, the aperture being located also to the bottom portion and communicative with an interior of the main body; and
an anti-drop system, located inside the main body at a place respective to the aperture, further including an infrared detection module and an angle-limiting unit electrically coupled with the infrared detection module, the infrared detection module being to detect a distance between the bottom portion of the main body and a first detection surface, the infrared detection module further including an infrared emitting unit and an infrared receiving unit, the infrared emitting unit being to emit an infrared signal to the first detection surface, the infrared signal producing a first boundary signal and a second boundary signal after the infrared signal passes through the angle-limiting unit, an angle being formed by the first boundary signal and the second boundary signal, the infrared receiving unit being to receive an infrared receiving signal that is the reflected signal of the first boundary signal by the first detection surface.

Abstract
A self-propelled apparatus includes a main body and an anti-drop system. The main body includes an aperture located at a bottom portion thereof and communicative with an interior thereof. The anti-drop system located inside the main body respective to the aperture includes an infrared detection module and an angle-limiting unit electrically coupled with the infrared detection module. The infrared detection module detects a distance between the bottom portion and a first detection surface. The infrared detection module includes an infrared emitting unit and an infrared receiving unit. The infrared emitting unit emits an infrared signal to the first detection surface. The infrared signal produces a first boundary signal and a second boundary signal after the infrared signal passes through the angle-limiting unit. The infrared receiving unit receives a reflected signal of the first boundary signal with respect to the first detection surface.
