Abstract
The utility model relates to a liquefied petroleum gas level sensor for a dual-fuel vehicle, which is a sensor to convert the lifting change of liquid surface in a pressure container into an electrical signal. The problems of few segments of the liquid level display, rudeness, and complicated manufacture of the existing sensor. The utility model is characterized in that a columnar pointer body which is on the end of a float driving device, and is movable mated with a cake-shaped combination valve is provided with a magnet, a pointer and a fan-shaped shielding sheet which is extended into an arc-shaped groove of a plastic frame which is fixed and is provided with an infrared pair pipe. The shielding sheet is rotated in the arc-shaped groove of the plastic frame, and shields the infrared light to provide signals to associated circuits for controlling the orderly lightning and extinguishing of a light emitting diode.
Description
The liquid level that the utility model relates to a kind of dual-fuel automobile liquefied petroleum gas (LPG) shows.
The utility model belongs to the sensor that liquid surface lifting variation in the pressurized container is converted to electrical signal.
Original sensing mode adopts dry reed-pipe or Hall element to realize showing that its segmentation is few more, shows very roughly, makes pretty troublesome.
The utility model is in order to provide a kind of dual-fuel automobile liquefied petroleum gas (LPG) liquid level to show sensing device, with a float with on the liquid level or down, motion with a cover mechanism and pair of magnet transmission float, become and rotatablely move, drive a pointer body motion that has pointer and shielding plate, shielding plate retaining infrared light, pointer indicating graduation dish, thereby what of the liquefied petroleum gas (LPG) in the expression pressurized tank play the effect of sensing.
The utility model is a float driving mechanism end on combination brake switch and proporting, on the rotating column pointer body of this end, magnet, pointer and fan-shaped shielding plate are arranged, shielding plate stretches in the plastic frame curve bath that the post that is fixed is equipped with infrared tube, shielding plate rotates in curve bath with the pointer body rotation and blocks infrared light, and pointer body and plastic frame are installed in the exterior edge face of pie combinaing valve body.The combinaing valve body interior edge face is provided with a magnet corresponding to exterior edge face magnet place, and magnet is installed on the supporting frame that may rotate, and the supporting frame the other end is hinged by connecting rod and float, and float moves up and down, and will have the pointer body driven rotary of pointer and fan-shaped shielding plate.Pointer indicating graduation dish, fanning strip is used for blocking infrared ray, and when pointer was indicated " 1 " under the effect of magnet, fanning strip also produced outside the frame of rectifying, and several infrared tubes are all worked.Make interlock circuit work through the lead transmission, several light emitting diodes are bright entirely, show that the liquefied petroleum gas (LPG) in the pressurized tank is full of this moment, along with automobile uses this gas, liquid in jar also slowly reduces, pointer returns and shows, fanning strip blocks infrared tube one to one, and light emitting diode extinguishes immediately one by one, when pointer indication " 0 ", fanning strip has kept off the light that all infrared emission tubes send, receiving tube is not worked, and lead is transmission of electric signals not, and Light-Emitting Diode (LED) goes out entirely, show that the liquefied petroleum gas (LPG) in the jar uses up this moment, thereby played the effect of sensing.
The utility model utilizes infrared tube under fanning strip blocks effect, changes optical signal into electrical signal.Liquefied petroleum gas (LPG) in the sensed pressure jar, so as to know what, succinct, directly perceived, come into plain view, the more important thing is that no-spark produces, Security is good, system is reliable.
The utility model is provided by figure below, and Fig. 1 is provided with combination brake switch and proporting plan view of the present utility model, and Fig. 2 is provided with the utility model combination brake switch and proporting plan view.
Below in conjunction with details and the working principle of pattern explanation according to specific implementation sensing of the present utility model.
This device is installed on the combinaing valve body (11), combination brake switch and proporting is fastened on the pressurized tank, and become 30 ° of angles to put, float (1) is in the jar, float (1) is with on the liquid level, down, by connecting rod under the effect of supporting frame (2), make magnet (3) rotation, because magnet attracts each other, so magnet (4) also rotates, because magnet (4) is fixed in the pointer body (5), so pointer body (5) rotates, pointer (7) is an one with fanning strip (6) and pointer body, so pointer (7), fanning strip (6) also rotates simultaneously, fanning strip rotates in plastics are rectified frame (9) medial arc groove, and the top of curve bath is equipped with many to infrared light emission tube (12), and the bottom is equipped with many to the infrared light receiving tube.After connecting power supply, the electric current of storage battery is lighted all infrared light emission tubes (12) through current-limiting resistance.Because the deflection angle of pointer (7) only is limited to 80 ° of scopes from the initial point to the terminal point, so infrared light emission, reception can only be evenly distributed by liquefied petroleum gas (LPG) segmentation demonstration in 80 ° to pipe, give definitely to indicate 1-3/4,3/4-1/2,1/2-1/4, the demonstration of 1/4-0 section, be engraved in respectively on the dial (8), and the fanning strip on the pointer body blocks in curve bath one by one and relieving one by one, the infrared light that the infrared light emission tube emits, make the infrared light receiving tube receive the optical signal of coming and be transformed into electrical signal, the electrical signal of reception being come with one group of lead (10) is transferred to interlock circuit one by one, makes many light emitting diodes only only light or only extinguish.
