Description
Technical field
A kind of power-off protector is the utility model is related to, it is particularly a kind of to be used to prevent vehicle from being caused damage by water logging
Power-off protector, belong to technical field of automobile accessories.
Background technology
With the continuous improvement of people's living standards, automobile be increasingly becoming people life in, necessary article it
One.But automobile quantity it is swift and violent it is increased instantly, use knowledge of the people for vehicle but scarcity all the more, this results in vapour
Car in use, once running into emergency case, if correct solution method can not be taken, can be caused to automobile equipment
Damage, scrapping for vehicle can be directly contributed if serious.For example, when automobile causes engine misses running into because of water logging situation
When, it should at once cut off the electricity supply, ignition operation must not be carried out to engine again；Otherwise once because of maloperation, and beat
Firer makees, and just easily engine interior is intake, so as to cause engine failure or scrap.So in order to avoid because of maloperation
And vehicle is caused to damage, professional needs to be designed the safeguard function of vehicle.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of simple in construction, install convenient and energy
Enough water logging situations for accurately detecting vehicle, and the automobile-used power-off protector of power down process is carried out to vehicle in time.
Problem described in the utility model solves by the following technical programs：
A kind of automobile-used power-off protector, including detection piece, control circuit and gas Corrent breaker；The detector is arranged on car
Air inlet pipe at；The negative pole connection of the gas Corrent breaker and vehicle battery；The detection piece by detection signal transmit to
The signal receiving end of control circuit, then the break-make by control circuit control gas Corrent breaker；The detection piece is level sensor.
Above-mentioned automobile-used power-off protector, the control circuit include comparator and adjustable potentiometer；The detection piece with than
Positive terminal compared with device connects；First pin of the adjustable potentiometer is connected with power end, second pin and comparator it is anti-phase
End connection；The output end of the comparator is connected with gas Corrent breaker.
Above-mentioned automobile-used power-off protector, the model IC65N of the gas Corrent breaker.
The utility model is detected by level sensor to the water flooding degree of vehicle, and waterflooding water level can be entered in real time
Row monitoring, after waterflooding water level exceeds set height of water level, control circuit can be timely transmitted a signal to, make control electric
Road control gas Corrent breaker disconnects, and so as to complete to cut off the work of vehicle power supply, vehicle is effectively prevented after water logging, because grasping by mistake
Make and cause vehicle damage or the accident such as scrap.The utility model is simple in construction, install convenient, and is not limited by vehicle, is applicable
In on any vehicle.
Brief description of the drawings
Fig. 1 is the utility model electrical schematic diagram；
Fig. 2 is level sensor and air inlet pipe scheme of installation.
Each list of reference numerals is in figure：1. air inlet pipe, SC. level sensors, B. comparators, QD. gas Corrent breakers, RP. are electric
Position device.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model includes detection piece, control circuit and gas Corrent breaker QD；The detector is set
Put the entrance (can be arranged at air inlet inside pipe wall or outer wall) in the air inlet pipe 1 of vehicle；The gas Corrent breaker QD is (described
Gas Corrent breaker QD principle is to discharge the principle of a large amount of gases after being powered using gas generator rapidly, promotes pre-cut
The copper coin contact point opened, so that metallic plate disconnects, realize the purpose of power-off) it is connected with the negative pole of vehicle battery；The inspection
Survey part to transmit detection signal to the signal receiving end of control circuit, then gas Corrent breaker QD break-make is controlled by control circuit；
The detection piece is level sensor SC.
Control circuit described in the utility model includes comparator B and adjustable potentiometer RP；The detection piece is compared with
Device B positive terminal connection；The first pin of the adjustable potentiometer RP is connected with power end, and second pin is anti-with comparator B's
Phase end connects；The output end of the comparator B is connected with gas Corrent breaker QD.Institute comparator model LM393, the comparator are defeated
Go out, signal is clean, and waveform is good, and driving force is strong, more than 15mA, to ensure the drive actions of driving gas dynamic circuit breaker electrical equipment.The gas
Body circuit breaker QD model IC65N.
Workflow of the present utility model is, when level sensor is detected as anhydrous state, D0 outputs are high level, gas
Body circuit breaker is failure to actuate；When level sensor detects water signal, that is, automobile is in waterflooding state, D0 exports low electricity
It is flat, voltage is produced between A0, so as to control gas Corrent breaker to work.
