Description

Technical Field

[0001] The utility model relates to an infrared transmitter. Background Art

[0002] At present, infrared transmitters can be used in the field of track leveling detection. For example, a track detection vehicle is disclosed in the Chinese patent with announcement number CN204736863U, which uses an infrared transmitter to emit infrared light, which is reflected by the track and then fed back to the central processor to detect the flatness of the track. There are many types of existing infrared transmitters. For example, a wireless infrared transmitter is disclosed in the Chinese patent with announcement number CN202034968U. However, the infrared light emitted by some existing infrared transmitters is weak and cannot meet the use requirements of track leveling detection. Utility Model Content

[0005] The housing is provided with mounting holes corresponding one to one with the light emitting components;

[0006] The light emitting assembly is installed in the corresponding mounting hole and is used to emit infrared light outward;

[0007] Wherein, the light emitting assembly comprises a light-transmitting plate, a reflective cup, a light source plate and a pressing ring which are sequentially arranged in the corresponding mounting holes from front to back;

[0008] A boss portion protruding radially inward is provided in the front end portion of the mounting hole, a through hole is provided on the inner side of the boss portion, and the boss portion is located in front of the light-transmitting plate;

[0010] The light source board is provided with an infrared LED;

[0011] The reflective cup cover is located outside the infrared LED and is used to reflect the infrared light emitted by the infrared LED.

[0012] Furthermore, a first sealing ring is provided between the light-transmitting plate and the boss portion.

[0013] Furthermore, the infrared transmitter also includes a driving board and a power supply component;

[0014] The driving board is installed in the housing, and the driving board is connected to the light source board and is used to drive the infrared LED on the light source board to emit infrared light;

[0015] The power supply component is installed in the housing, and the power supply component is connected to the driving board and is used to supply power to the driving board.

[0016] Further providing a specific structure of the power supply component, the power supply component comprises a power supply battery, a positive electrode conductive sheet, a negative electrode conductive sheet, a conductive spring and a screw cap;

[0017] The housing is provided with a battery compartment for accommodating the power supply battery;

[0018] The positive electrode conductive sheet is arranged in the housing and is used to abut against the positive electrode of the power supply battery in the battery compartment;

[0019] The negative electrode conductive sheet is connected to the rotary cover, the conductive spring is connected to the negative electrode conductive sheet, and the rotary cover is detachably connected to the outer shell so that the conductive spring is against the negative electrode of the power supply battery in the battery compartment.

[0028] Furthermore, two light-emitting components are arranged in parallel.

[0029] After adopting the above technical solution, the infrared light emitted by the infrared LED will diverge in all directions. The reflective cup cover on the outside of the infrared LED can therefore reflect the infrared light diverging in all directions and converge it in one direction, so that the converged infrared light passes through the light-transmitting plate and then through the through hole to be emitted outward. The reflection and convergence effect of the reflective cup increases the intensity of the infrared light emitted outward, so as to meet the use requirements of track leveling detection.
