The present invention relates to a cooling device of an automobile, and in particular, by detecting the amount of engine coolant in the automobile and lighting a warning light on the dashboard and generating a buzzer when the amount is below a certain amount, the driver accurately determines the replenishment time of the engine coolant to overheat the engine. The present invention relates to an engine coolant amount display device of a vehicle using a tide sensor.

Generally, a cooling system of a vehicle is a device for cooling a part of the heat generated by the combustion of a mixer to prevent overheating of an engine to facilitate operation, and its purpose is to prevent premature ignition, improve charging efficiency, and modify it. And crack prevention, smooth lubrication, and the like.

If the engine is overheated, the components will be deformed, the oil film breakdown of lubricant, lack of lubricating oil, engine output will be reduced, and if the engine is over-cooled, power will be reduced, fuel consumption will increase, oil dilution and bearing. Negative abrasion and the like occur, and the cause of the engine heating is caused by slipping of the fan belt, scaling on the water jacket (path), leakage of coolant, and poor thermostat.

The cooling methods include air cooling type and water cooling type, and the electronic air cooling type is a type that dissipates heat by directly contacting the engine with the atmosphere, and there is no replenishment of cooling water, freezing, leakage of cooling water, etc. There is an advantage, but there is a disadvantage that the engine temperature is easy to change and the cooling is uneven, so it is easy to overheat, there is a natural ventilation, forced ventilation.

In addition, the latter water-cooled type is provided with a cooling water passage in the cylinder block and the cylinder head to circulate the cooling water therein, and there are natural circulation type, forced circulation type, pressure circulation type, and sealing pressure type.

The radiator is a device for cooling the coolant absorbing heat in the coolant passages of the cylinder block and the cylinder head. The radiator cools the coolant heated in the engine by passing it through a heat sink to come into contact with air. This large and low flow resistance of air and coolant should be light and strong. Usually, it is installed in the front of the car to cool the heat by wind, and it has a gap on the metal plate with good thermal conductivity to overlap and install a tube through which water flows. The cooling effect is increased by the size ratio, and the water flowing through the tube is cooled by cooling the metal plate.

However, such a conventional cooling device does not have a warning display even if the engine coolant is insufficient, and thus, there is an inconvenience in that the driver needs to check the engine room directly, and the engine overheats when the amount of coolant is not inadvertently checked by the driver. There is a problem that is, the overheated engine is not cooled, there is a problem that the parts are deformed, thereby causing a safety accident.

Accordingly, the present invention was devised to solve the above-mentioned problems, and when the amount of engine coolant is sensed to detect an amount of the engine coolant of the vehicle, the driver lights up the warning lamp of the instrument panel and generates a buzzer, thereby supplementing the engine coolant. The purpose of the present invention is to provide an engine coolant level indicator of a vehicle using a tide gauge sensor that can accurately determine the timing to prevent the engine from overheating.

The present invention for achieving the object as described above, the coolant tank for storing the coolant of the engine, and the tide level sensor for detecting the elapsed time that the ultrasonic pulse is attached to the coolant tank and emitted from the surface of the coolant, the bath A distance calculator that calculates the time detected by the hierarchical sensor as a distance, a controller that outputs a control signal by comparing the distance signal calculated by the distance calculator with a preset value according to the capacity of the coolant tank, and outputs from the controller And a buzzer configured to generate a warning sound by receiving a control signal output from the controller and a warning light that is turned on in response to the control signal.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

An engine coolant amount display device for an automobile using a tide gauge sensor according to the present invention includes a coolant tank 1 in which coolant of an engine is stored, as shown in FIG. An tide gauge sensor (2) which detects an elapsed time when the ultrasonic pulse emitted and emitted from the coolant tank (1) is reflected from the coolant surface; A distance calculator (3) for calculating a time detected from the tide gauge sensor (2) as a distance; A controller (4) for outputting a control signal by comparing the distance signal calculated from the distance calculator (3) with a preset value according to the capacity of the cooling water tank (1); A warning light 5 which is turned on in response to a control signal output from the controller 4; It consists of a buzzer 6 for receiving a control signal output from the control unit 4 to generate a warning sound.

Referring to the operation and effect of the present invention configured as described above in detail.

First, when the tide gauge sensor 2 is attached to the coolant tank 1 of the engine room in order to detect the amount of engine coolant in the vehicle, the tide gauge sensor 2 is connected to the surface of the coolant stored in the coolant tank 1. It emits ultrasonic waves and detects the elapsed time of reflection.

The signal according to the elapsed time detected by the tide gauge sensor 2 is calculated as a distance through the distance calculator 3 and then output to the controller 4.

The control unit 4 compares the signal input from the distance calculator 3 with a preset value according to the capacity of the coolant tank 1, and when the signal input from the distance calculator 3 is equal to or less than a predetermined amount, When the amount of current coolant stored in the coolant tank 1 is insufficient, a control signal is output.

The control signal output from the controller 4 turns on the warning light 5 of the instrument panel according to the amount of coolant stored in the coolant tank 1, while the warning light 5 of the instrument panel that is turned on as described above is normal. If not, the controller 4 generates a buzzer 6 by outputting a control signal, thereby inducing the driver to replenish the amount of engine coolant.

Therefore, the driver can appropriately determine the replenishment timing of the engine coolant.

As described in detail above, the present invention, by detecting the amount of engine coolant in the car to turn on the warning light on the instrument panel when the predetermined amount or less, and by generating a buzzer to accurately determine the replenishment time of the engine coolant to prevent the engine overheating By preventing overheating of the engine, it is possible to prevent deformation of parts due to overheating of the engine, thereby preventing safety accidents that may occur, and to check the abnormal condition of the vehicle in advance. It has the effect of maximizing efficiency.
