Abstract
An engine oil level sensor of a gasoline engine comprises a tank body of the gasoline engine, wherein a sensor shell is arranged in the tank body; a through hole is arranged at the upper end of the sensor shell; a floater is arranged in the sensor shell; a metal guide rod is fixed in the floater; and the two ends of the metal guide rod are exposed at the upper and lower ends of the floater respectively. The engine oil level sensor is characterized in that a shaft stopping ring is arranged at the two ends of the metal guide rod respectively; a metal guide piece is arranged at the upper end of the sensor shell; the metal guide piece is externally connected with a conducing wire; a perforating hole is arranged in the through hole of the metal guide piece on the sensor shell; the floater drives the metal guide rod to axially move in the perforating hole of the metal guide piece; the lower end of the metal guide rod is conical; and the lower end of the conical metal guide rod is in contact with the tank bottom. The engine oil level sensor disclosed by the utility model has the advantages of simple structure, easiness for manufacture and low cost; and the engine oil level sensing response is sensitive, and the normal use of the sensor is ensured.
Description
Technical field
The utility model relates to petrol engine machine oil position perceptron.
Background technique
At present, the oil level perceptron that general gasoline engines adopts is a contact contact formula fuel level sensor, and the lower end of float is fixed with a cylindrical metal contact in its shell; On shell, be fixed with the metal contact and be positioned at the lower end of float, when the hard contact that is displaced downwardly to the float lower end with the decline of oil level when float contacted with the metal contact, the flame-out sheet of petrol engine igniter was connected with ground; The petrol engine igniter can not be lighted a fire; Petrol engine quits work, and reaches the purpose of protection petrol engine, but the shortcoming of its existence is: when the iron in the machine oil is cut or impurity when too much; Iron is cut with impurity and is contacted with hard contact or metal contact; Cause that easily hard contact does not contact just conducting with the metal contact, error cut-off machine occurs, influenced the proper functioning of petrol engine.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming that prior art exists, to provide the position perception of a kind of machine oil to be quick on the draw, do not receive the influence of machine oil impurity, makes simply, and cost is low, petrol engine machine oil position perceptron easy to use.
The technological scheme of the utility model petrol engine machine oil position perceptron is: comprise the casing of petrol engine, in casing, be equipped with the perceptron shell, open the hole in the upper end of perceptron shell; In the perceptron shell float is arranged; Fixing metal guide rod in the float, the upper and lower end of float is exposed at the two ends of metal guide rod respectively, it is characterized in that shaft block ring is installed at the two ends of said metal guide rod; Metallic laminas is installed in upper end at the perceptron shell; The through hole that metallic laminas external wire, metallic laminas are positioned at the perceptron shell has perforation, and float drives metal guide rod and in the perforation of metallic laminas, axially moves; Said metal guide rod lower end is taper, and the metal guide rod lower end of taper contacts with at the bottom of the case.
The utility model discloses a kind of petrol engine machine oil position perceptron,, shaft block ring is installed in the perceptron shell at the two ends of metal guide rod through float and metal guide rod are installed; Metallic laminas is installed in the upper end of perceptron shell, and the metallic laminas external wire during use is fixed on this perceptron the bottom of diesel engine crankshaft; Float fluctuates according to the height of machine oil oil level, and when in the casing of petrol engine during inorganic oil, float then sinks to the bottom of casing; This moment, the lower end of metal guide rod contacted with at the bottom of the case, and the shaft block ring of metal guide rod upper end contacts closing of circuit with metallic laminas; Transmit thereby machine oil warning oil level signal is produced, send the signal of warning, if when in the casing enough machine oil being arranged; Machine oil floats float, has avoided metal guide rod lower end and contacting at the bottom of the case, and shaft block ring contacts with metallic laminas; The metal guide rod lower end is designed to taper, machine oil position perceptron is quick on the draw, do not receive the influence of machine oil impurity.This product structure is simple, and is easy to manufacture, and cost is low, and the perception of machine oil position is quick on the draw, and guarantees the normal use of perceptron.
The utility model petrol engine machine oil position perceptron, said metal guide rod lower end and float bottom surface be 2mm apart from S, the distance L that the float bottom surface is in bottom with the perceptron outer casing bottom is 2mm.Can guarantee promptly and accurately to react machine oil position height.
Description of drawings
Fig. 1 is the structural representation of the utility model petrol engine machine oil position perceptron.
Embodiment
The utility model relates to a kind of petrol engine machine oil position perceptron, and is as shown in Figure 1, comprises the casing of petrol engine; In casing, be equipped with perceptron shell 1, open hole 11, float 2 is arranged in the perceptron shell in the upper end of perceptron shell; Fixing metal guide rod 3 in the float, the upper and lower end of float is exposed at the two ends of metal guide rod respectively, it is characterized in that shaft block ring 31 is installed at the two ends of said metal guide rod; Metallic laminas 12 is installed in upper end at perceptron shell 1; The through hole that metallic laminas external wire 4, metallic laminas are positioned at the perceptron shell has perforation 13, and float 2 drives metal guide rod 3 and in the perforation 13 of metallic laminas 12, axially moves; Said metal guide rod lower end 32 is taper, the metal guide rod lower end of taper with 5 contact at the bottom of the case.Through float 2 and metal guide rod 3 are installed in perceptron shell 1, at the two ends of metal guide rod shaft block ring 31 is installed, in the upper end of perceptron shell metallic laminas 12 is installed; Metallic laminas external wire 4 during use is fixed on this perceptron the bottom of diesel engine crankshaft, and float 2 fluctuates according to the height of machine oil oil level; When in the casing of petrol engine during inorganic oil, float then sinks to the bottom of casing, this moment metal guide rod 3 lower end 32 with 5 contact at the bottom of the case; The shaft block ring 31 of metal guide rod upper end contacts with metallic laminas 12, and closing of circuit transmits thereby machine oil warning oil level signal is produced; Send the signal of warning, if in the casing when enough machine oil is arranged, machine oil floats float 2; Avoided metal guide rod 3 lower ends 32 and 5 contact at the bottom of the case, shaft block ring 31 contacts with metallic laminas 12, and the metal guide rod lower end is designed to taper; Machine oil position perceptron is quick on the draw, does not receive the influence of machine oil impurity.This product structure is simple, and is easy to manufacture, and cost is low, and the perception of machine oil position is quick on the draw, and guarantees the normal use of perceptron.Said metal guide rod lower end 32 is 2mm with float 2 bottom surfaces 21 apart from S, and the distance L that float 2 bottom surfaces 21 are in bottom with perceptron shell 1 bottom 14 is 2mm.Can guarantee promptly and accurately to react machine oil position height.
