Abstract
The utility model discloses an improved magnetoelectric liquid level sensor for liquefied petroleum gas, which utilizes short distance magnetic action and long distance electric action principles to realize magnetic and electric liquid level conversion directive functions of the same sensor. The utility model is characterized in that: with retaining the float transmission structure in original liquefied petroleum gas steel bottle; the original magnet-pointer-integrated sensing action structure is changed into a dial structure that can rotate around a fixed slewing axis; that is, two cylindrical magnets are embedded around the dial; under the magnetic function of the float transmission structure, the dial derives the pointer to rotate thus indicating liquid level. At the same time, the dial drives a rocker made of elastic metal sheet to rotate, thus changing the resistance value of the printed circuit board contacted with the rocker; the changing resistance value and the outgoing line participate in the operating circuit of the fuel meter on the flight instrument panel, thus the function of indicating liquid level through the fuel meter is realized.
Description
Technical field
The utility model provides a kind of improved Vehicular liquefied petroleum gas liquid level sensor.
Background technology
At present, the liquefied petroleum gas (LPG) liquid level sensor that uses on the automobile that acts as a fuel with liquefied petroleum gas (LPG), the contactless magnetic transducing measuring principle of general employing is made, promptly pass through the change of float height on the liquid level in the liquefied petroleum gas steel cylinder, do corresponding moving through the drive of float connecting rod at the magnet of liquefied gas one side of liquefied petroleum gas steel cylinder output combination of valve body, because being brass, makes by the output combination valve, can not shield the magnetic line of force, thereby the magnetic line of force of the mobile generation of above-mentioned magnet distribution change, effect is positioned at output combination of valve body appearance and the magnet generation motion of a side.And this motion magnet and pointer are made of one, thereby can how much indicate interior liquid level height of liquefied petroleum gas steel cylinder or storage according to the position change of pointer.The liquid level sensor that above-mentioned magnetic principles is made, the installation site is limited in closely during use, on the copper liquefied petroleum gas (LPG) output combination valve, can't realize being positioned at remote pilot dash board oil scale also indicate synchronously liquid level height or storage what, thereby the driver also just can't grasp the operating position of understanding liquefied petroleum gas (LPG) at any time.
Summary of the invention
The purpose of this utility model is to provide a kind of novel magneto-electric Vehicular liquefied petroleum gas liquid level sensor, utilize closely magnetic action principle and remote electro ultrafiltration principle to realize what export on the combination valve and the dual synchronous indication on the control instruments leaf fat scale at steel cylinder for liquefied petroleum gas (LPG) liquid level height or storage, realized the deixis of fuel level gauge, saved the expensive import magnetoelectricity conversion display device of additionally setting up, for enterprise has reduced cost, created benefit.
The utility model is to realize like this, keep the float gear train in the former liquefied petroleum gas (LPG) steel cylinder, magnet and pointer with output combination of valve body outside surface one being made of one of side structure on the former steel cylinder, change the turntable structure spare that rotates around stationary shaft into, promptly be embedded in the periphery of rotating disk with two cylindrical magnetic irons, pointer and index dial are installed in the central authorities of rotating disk, and when pointer rotated with rotating disk, the upper surface that coils at fixed quarter just can carry out the liquid level indication.And the rocking arm that this moment, respective fixation was made by elastic sheet metal on rotating disk under the effect of elastic force, closely contacts with the P.e.c. of index dial lower surface, forms the variable circuit of resistance value.Do corresponding when mobile when liquefied petroleum gas (LPG) level change in the steel cylinder causes with the magnet of float interlock, change because of magnetic line of force distribution, the magneticaction that produces makes rotating disk rotate around stationary shaft in rotating disk periphery cylindrical magnetic iron, then pointer will indicate corresponding liquid level height or storage what.Simultaneously, the rocking arm that elastic sheet metal is made contacts the resistance value adjusted circuit that forms with index dial lower surface P.e.c., participate in fuel level gauge operating circuit on driver's instrument panel by extension line, on fuel level gauge, just can realize just or what synchronous indication of storage liquid level.

Beneficial effect:
The utility model magnetoelectric liquefied petroleum level sensor for vehicle shows through performance test and entrucking are on probation, Have stable and reliable working performance, the characteristics of indicating correct, that has realized same sensor finishes magnetic and electricity Two kinds of conversion deixises, saved the expensive import magnetoelectricity conversion display unit of additionally setting up, For having reduced cost, enterprise created benefit.
Embodiment
Be described in further detail below in conjunction with the structure of accompanying drawing the utility model magneto-electric Vehicular liquefied petroleum gas liquid level sensor.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4,1 is loam cake, and 9 is lower cover, and index dial 3 is fixed on down and covers, and 14 for being arranged on down the stationary shaft that covers.Rotating disk 7 can freely rotate around stationary shaft 14, is provided with steel ball 13 between rotating disk 7 and the stationary shaft 14, its objective is in order to allow rotating disk 7 rotate around stationary shaft 14 more leggiero.Pointer 2 is bonded in rotating disk 7 central upper and passes on the bead in hole, index dial 3 garden, does to rotate synchronously with rotating disk 7.6,8 for symmetry is embedded in the cylindrical magnetic iron of rotating disk 7 peripheries, for making magneto motive homogeneity, the cylindrical magnetic iron more than a pair of can be set also at the periphery of rotating disk 7.12 is the metal pressure ring, and the rocking arm that 10,11 elastic sheet metals are made is fixed on the rotating disk, utilizes the resilient force of rocking arm 10,11, closely contact with index dial 3 lower surface P.e.c., but the circuit of formation resistance value real-time change.Participate in the oil operating circuit of scale of pilot dash boards by extension line 5,6.When in the steel cylinder during liquefied petroleum gas (LPG) liquid level change, be positioned at liquefied gas one side of steel cylinder output combination of valve body, the magnet that is connected with the float connecting rod produces motion, so under the effect of variable magnetic force line, rotating disk 7 is rotated because of its peripheral cylindrical magnetic iron 6,8 stressed backs produce around stationary shaft 14, follow pointers 2 that rotating disk 7 rotates synchronously can indicate corresponding liquid level height or storage what.Meanwhile, the rotation of rotating disk 7, make rocking arm 10,11 that elastic sheet metal makes and index dial 2 lower surface P.e.c. closely contact the resistance-variable circuit of composition, participate in fuel level gauge operating circuit on the pilot dash boards by extension line 5,6, thereby on fuel level gauge, realize what coincident indicator of liquid level height or storage.
