Abstract:
1. A distance detecting sensor, comprising: a housing; a focusing lens; a circuit board; a transmitter device for transmitting infrared rays; a receiver device for sensing the reflected light rays; and a shielding case for a shielding function wherein the housing comprises a main body and two circular apertures located on a top surface of the main body; wherein the lens is installed in the main body of the housing and comprises transmitting lens and receiving lens installed at positions of the apertures of the housing; wherein the circuit board is installed in the main body of the housing and provided with several electronic elements for signal processing; wherein the transmitter device is installed on the circuit board and transmits the infrared light rays to the transmitting lens; wherein the receiver device is a distance detecting sensing module, which is installed on the circuit board and receives and senses the reflected light rays focused by the receiving lens; wherein the shielding case is installed around the transmitter device and the receiver device, for preventing electromagnetic interference; wherein the transmitter device and the receiver device are installed on the same side of the circuit board; wherein the circuit board is provided, in positions where the transmitter device and the receiver device are installed, with first and second via holes, such that the transmitted light rays from the transmitter device can travel through the first via hole to the transmitting lens and the reflected light rays received by the receiving lens can travel through the second via hole to the receiver device.
