A distance detection induction device comprises a housing, a condensing lens, a circuit board bearing multiple electronic components, an infrared light emitting means for emitting the infrared light, and a light receiving means for receiving and sensing the reflected infrared light. The housing comprises a main body and two round openings on the top of the main body. The condensing lens has an emitting lens and a receiving lens respectively located inside two round openings. The circuit board bearing the multiple electronic components is used for processing signal, and is mounted inside the main body of the housing. The infrared light emitting means is infrared light-emitting diode, and emits the infrared light to the emitting lens. The light receiving means is the distance detecting sensing module, and senses the reflected light focused by the receiving lens. Said distance detection induction device further comprises positioning brackets that match with the housing, and is fixed to the housing. The positioning brackets includes the emitting positioning bracket and the receiving positioning bracket that respectively hold and accurately position the infrared light emitting means and light receiving means. The distance detection induction device of the present invention has higher positioning precision so as to enhance the induction performance of the whole device. |
