Abstract:
1. A distance detection determination device comprising: a housing, a condensing lens, a circuit board, an infrared light emitting means, a light receiving means for receiving and sensing the infrared light which is emitted by said infrared light emitting means and reflected by target, and a shielding cover for shielding; wherein said housing comprises a main body and two round openings on the top of said main body; wherein said condensing lens comprises an emitting lens and a receiving lens respectively located at said two round openings of said housing; said circuit board bearing multiple electronic components is used for processing signal, and wherein said circuit board is mounted inside said main body of said housing; said infrared light emitting means is an infrared light-emitting diode mounted on said circuit board, and emits the infrared light to said emitting lens; said light receiving means is a distance detecting sensing module mounted on said circuit board to sense the reflected light focused by said receiving lens; said shielding cover is mounted around said infrared light emitting means and light receiving means to shield them from electromagnetic interference; wherein the distance detection induction device further comprises positioning brackets that match with said housing and are fixed to said housing; wherein said positioning brackets include an emitting positioning bracket and a receiving positioning bracket that respectively hold and accurately position said infrared light emitting means and light receiving means; wherein said emitting positioning bracket includes two protruding parts respectively at the two sides of said emitting positioning bracket, and positioning grooves inside said housing match with said two protruding parts.
