Abstract
The utility model discloses a liquid level sensor for a cooling liquid, which comprises a liquid level sensor body and an induced magnet capable of floating on the cooling liquid, wherein the liquid level sensor body comprises a liquid level sensor casing and a dry reed pipe; the dry reed pipe is arranged in the liquid level sensor casing; a wiring harness slot connected with a warning lamp is formed on the liquid level sensor casing; the dry reed pipe is connected with the wiring harness slot; the liquid level sensor body is installed in an installation cavity which extends to an inner cavity of an expansion water tank and is not connected with the inner cavity; and the induced magnet is positioned in the expansion water tank, and moves upwards and downwards and is sleeved on the installation cavity. After the utility model is mounted in the expansion water tank, when the cooling liquid level reaches a warning surface, the utility model can be connected with the warning lamp and send the warning; and in addition, the utility model has the characteristics of low comprehensive cost, simple structure, convenient installation, and good popularization and application values.
Description
Technical field
The utility model relates to a kind of automobile engine cooling liquid liquid level warning sensor, belongs to motor car engine attachment technique field.
Background technology
Along with the continuous progress of auto industry, increasing new technology constantly is applied on the automobile, make driver and crew can be comfortable driving a car freely.But the cooling-liquid level height does not also have the relevant detection device in the automobile radiators expansion tank at present, still there is the driver to open deck lid and checks the cooling-liquid level height, if the driver forgets inspection and causes liquid coolant to lack, may cause serious consequences such as burning out engine, bring very large economy loss to the car owner.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of automobile liquid coolant liquid level sensor is provided, can sends warning when the liquid coolant liquid level arrives the warning liquid level.
In order to solve the problems of the technologies described above, the utility model comprises liquid level sensor body and can be on liquid coolant floating induced magnet, the liquid level sensor body comprises liquid level sensor housing and tongue tube, tongue tube is arranged in the liquid level sensor housing, the liquid level sensor housing is provided with the wire harness slot that connects alarm lamp, tongue tube is connected with the wire harness slot, the liquid level sensor body be installed in the inner chamber that extend into expansion tank and with installation cavity that inner chamber does not communicate in, induced magnet is in the expansion tank, and induced magnet is moving up and down to be enclosed within on the installation cavity.
Peg graft convenient and be convenient to measure the liquid coolant liquid level for wire harness, described wire harness slot is arranged on the top of liquid level sensor housing, and tongue tube is embedded in the bottom of liquid level sensor housing.
In order to make the liquid level sensor housing easy for installation, fixing reliable, described liquid level sensor housing top is provided with locating piece and flexible fastening catch.
The beneficial effects of the utility model are: expansion tank is after installing the utility model, when the liquid coolant liquid level reaches warning face, the novel warning lamp of being informed of a case of this reality, send warning, and the utlity model has characteristics such as integrated cost is lower, simple in structure, easy for installation, have good popularizing value.
Description of drawings
Fig. 1 is a user mode synoptic diagram of the present utility model; Fig. 2 is this real novel liquid level sensor body structural representation;
Wherein: 1, expansion tank, 2, installation cavity, 3, the liquid level sensor body, 4, induced magnet, 5, the flexible fastening catch, 6, locating piece, 7, tongue tube, 8, the wire harness slot, 9, the liquid level sensor housing.
Embodiment
A kind of liquid coolant liquid level sensor as shown in Figure 1, it comprises liquid level sensor body 3 and can be on liquid coolant floating induced magnet 4, as shown in Figure 2, liquid level sensor body 3 comprises liquid level sensor housing 9 and tongue tube 7, tongue tube 7 is arranged on liquid level sensor housing 9 bottoms, liquid level sensor housing 9 tops are provided with the wire harness slot 8 that connects alarm lamp in the pilothouse, tongue tube 7 is connected with wire harness slot 8, liquid level sensor body 3 be installed in the inner chamber that extend into expansion tank 1 and with installation cavity that inner chamber does not communicate in 2, induced magnet 4 is in the expansion tank 1, induced magnet 4 moving up and down being enclosed within on the installation cavity 2, expansion tank 1 is that the casing of two parts up and down by injection molding is welded, before expansion tank 1 welding, at first can be sleeved on welding then on the installation cavity 2 of sealing of expansion tank 1 inside at induced magnet floating on the liquid coolant 4.Liquid level sensor housing 9 tops are provided with locating piece 6 and flexible fastening catch 5.When liquid level sensor housing 9 inserted in the installation cavity 2 of the sealing on the expansion tanks 1, the locating piece 6 of both sides was packed in the pickup groove of expansion tank 1, and flexible fastening catch 5 is stuck in below expansion tank 1 spacing preiection, and this moment, the liquid level sensor housing 9 was in place.
Embodiment: liquid coolant is injected expansion tank 1, this moment, induced magnet 4 was along with cooling-liquid level floats along installation cavity 2 tube walls, along with the consumption of liquid coolant (evaporation or leak) cooling-liquid level begins to descend, induced magnet 4 also descends with liquid level, when induced magnet 4 drops to the warning liquid level, induced magnet 4 is near the tongue tube 7 on the liquid level sensor housing 9, under the effect of the magnetic field magnetic line that induced magnet 4 produces, tongue tube 7 inner two reeds are magnetized and the contact of attracting each other, make alarm lamp wire harness loop connection in the pilothouse that is connected with wire harness slot 8, alarm lamp will light, and reminds the driver in time to add inject cooling liquid.After the driver adds inject cooling liquid, induced magnet 4 floats along installation cavity 2 tube walls along with cooling-liquid level again, and tongue tube 7 outside magnetic force disappear, and two reeds of tongue tube 7 inside are owing to the elasticity of itself is separated, the alarm lamp loop also just disconnects, and the alarm lamp in the pilothouse extinguishes.
