Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation.
As shown in Figures 1 to 6, the Non-contact vehicle liquid level sensor, including float 2, guide rod 1, resistor disc 7, one
Group contact 5, mounting base 3 and connector 4；2 sets of float can move up and down on guide rod 1, and guide rod 1 is hollow structure, resistance
Piece 7 and one group of contact are each provided in guide rod relatively, and resistor disc position is corresponded on float equipped with permanent magnet 6.
The material of float 2 and guide rod 1 is insulating materials, and permanent magnet is embedded in float, energized components and conductive oil
Liquid is non-contact, avoids electric quantity loss.
Resistor disc 7 and contact 5 are connected with the conducting wire 8 for extraction respectively, and guide rod is located in mounting base, mounting base and patch
It is connected between part by conducting wire.
One group of contact is to gather along the short transverse of guide rod contact arranged side by side.Contact is the elasticity of elastically deformable
Contact, contact are equipped with elastic slice, and permanent magnet attracts elastic slice, and the free end of elastic slice is contacted with resistor disc；Resistor disc is bar resistor
Piece, along guide rod short transverse be located at guide rod inner wall on.
Mounting base 3 is equipped with installation screw thread, is easily installed fixation；The top of guide rod 1 is equipped with for limiting to float
Limit plate limits the extreme position of float；Preferred limit plate is rubber slab, avoids generating abnormal sound and float damage
It is bad.
The height of float 2 is greater than 2 times of a contact height, it is ensured that at least one contact can connect with resistor disc
Touching.
Preferred embodiment are as follows:
Using insulating materials, isolation energized components and oil liquid connect the float and guide rod that sensor contact with conductive oil liquid
Touching；Guide rod boring structure is provided with a resistor disc, a good conductor contact set；Set of contacts is closed as needed
Contact in varying numbers is set, have between contact and conducting wire elastic slice connection, contact and resistor disc is non-contact, contact can be by permanent magnet
Attract.Contact set belongs to good conductor, and set of contacts unifies end connecting wire.
Resistor disc resistance value distribution is uniform, and resistance value is directly proportional to resistance leaf length, resistor disc one end connecting wire；Float pair
Resistor disc side is answered to inlay permanent magnet, resistor disc and set of contacts unification end conducting wire are connected on connector, are used for and overall wire sheaves
Docking.
Liquid level sensor vertical direction is installed in fluid reservoir, and float is floated downward as height of liquid level changes along guide rod
It is dynamic.Permanent magnet is inlaid with inside float, after the guide rod inner contact of float position is attracted by permanent magnet, corresponding position
Contact and resistor disc are attracted, two conducting wires are connected, and export corresponding voltage signal.
Since the contact of different location inside guide rod corresponds to the different location of resistor disc, each contact is corresponding not
Same resistance value, different resistance values can cause the difference of voltage again.So after liquid level variation causes float position to change, level sensing
Device can export the voltage signal of corresponding liquid level in the case where electrode does not contact conductive oil liquid.To efficiently solve conduction
