Abstract
The invention discloses an intelligent fuel tank with adjustable volume. A fuel tank exhaust pipe (2) is composed of a fixed pipe (5) and a sliding pipe (6). The fixed pipe (5) is fixedly connected with a tank body (4). The lower end of the sliding pipe (6) extends into the tank body (4); and the upper end of the sliding pipe (6) extends into the fixed pipe (5) and is connected with an output shaft of a motor (7). The motor (7) is controlled by a vehicular computer ECU (10). The vehicular computer ECU (10) is connected with an environment temperature sensor (12) through a signal processing circuit (11). The invention can adjust the position of the lower port of the sliding pipe in the fuel tank according to external temperature condition so as to automatically adjust the maximal injection amount of the fuel tank, therefore, the fuel tank can adapt with kinds of temperature environments in different seasons and areas; and the fuel oil overflow caused by high-temperature expansion can be avoided when more fuel oil is injected once by volume of the fuel tank at the maximal limit.
Description
Technical field
The present invention relates to a kind of automobile component, particularly the adjustable intelligent fuel tank of capacity.
Background technology
At present, the manned vehicle fuel tank generally leans on the height of pore in fuel tank of freeing pipe to control the fuel filling amount.During fuel filling, fuel tank air extractor vent valve is closed, and the air in the fuel tank is discharged through freeing pipe; Behind fuel oil contact freeing pipe lower end; The lower port of freeing pipe is in the below of fluid horizontal surface, and the air in the fuel tank can't normally be discharged, so just in fuel tank above form the aeroseal space; And produce pressure and make fuel tank can not continue fuel up, the fuel filling amount of this moment has just reached design-calculated maximum fuel adding amount.Why will control the fuel filling amount, be in order to ensure can from fuel tank, not overflowing behind the fuel oil expanded by heating.This highly can not change traditional fuel tank behind design typification; Then the capacity of this fuel tank is unique confirms; The general value of the capacity of fuel tank is the safety value under the normal temperature; The oil spilling phenomenon still possibly take place in the vehicle that uses at high-temperature area like this, but does not make full use of the abundant fuel oil of volume storage of fuel tank again at low-temperature region.Therefore, traditional fuel tank can not adapt to all temps environment.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of intelligent fuel tank that can change the maximum fuel adding amount according to the variation of ambient temperature.
Technical scheme of the present invention is following: the intelligent fuel tank that a kind of capacity is adjustable; Have casing (4), on casing (4), be provided with fuel tank filler opening (1), fuel tank freeing pipe (2) and fuel tank air extractor vent (3), said fuel tank freeing pipe (2) is made up of stationary pipes (5) and sliding tube (6); Wherein, Stationary pipes (5) is captiveed joint with casing (4), and the lower end of said sliding tube (6) is lower than the lower surface of stationary pipes (5), and the lower end of sliding tube (6) is stretched in the casing (4); The upper end of said sliding tube (6) is stretched in the stationary pipes (5); And be connected with the output shaft of motor (7), said motor (7) is by vehicle-mounted computer ECU (10) control, and this vehicle-mounted computer ECU (10) is connected with environment temperature sensor (12) through signal processing circuit (11).
The present invention adopts intelligence control system, the environment temperature sensor in car detect external temperature higher in, information is sent to vehicle-mounted computer ECU through signal processing circuit; ECU sends instruction according to Temperature numerical to motor again; Sliding tube is moved down, and the lower port of sliding tube is reduced to a lower position, can form bigger seal cavity in the casing during fuel filling like this; The actual capacity of fuel tank reduces, and under high temperature expands, can not overflow casing to guarantee fuel oil; Environment temperature sensor detect external temperature lower in; ECU sends instruction according to Temperature numerical to motor; The control motor rotation makes on the sliding tube and moves, and the lower port of sliding tube is elevated to a higher position; Only form in the casing when making fuel filling and less can guarantee the seal cavity that fuel oil does not overflow, thereby utilize the volume of the fuel tank more fuel oil of once annotating to greatest extent.
The lower port of said stationary pipes (5) has in-flanges, and the outer wall of the inside edge of this in-flanges and sliding tube (6) fits, and the upper end of said sliding tube (6) has flanging, and the inwall of the outer edge of this flanging and stationary pipes (5) fits.Above structure can guarantee that on the one hand sliding tube only moves at above-below direction; And the friction between sliding tube and the stationary pipes is less; Can strengthen smoothness and reliability that sliding tube relative fixed pipe moves up and down, on the other hand, the in-flanges of stationary pipes lower end combines with the flanging of sliding tube upper end; Play a part spacingly, from stationary pipes, come off to prevent abnormal condition lower slider pipe.
The upper end of said sliding tube (6) is connected with motor (7) through drag-line (8), and this motor (7) is arranged on the top of stationary pipes (5), and said drag-line (8) is on the axial line of stationary pipes (5).Above structure is not only simple, compact, assembling easily, and draw materials conveniently, cost is low.
Retracing spring (9) is housed in said stationary pipes (5), the step surface butt in upper end of this retracing spring (9) and the stationary pipes (5), the upper surface of the lower end of retracing spring (9) and sliding tube (6) connects.Retracing spring is in compressive state all the time, and when motor unclamps drag-line, when sliding tube moved down, retracing spring provided power-assisted, sliding tube is moved down not only reliably but also quick.
Beneficial effect: the present invention adjusts the position of sliding tube lower port in fuel tank according to the temperature conditions in the external world; Thereby realized automatically regulating to the maximum adding amount of fuel tank; Make fuel tank can both adapt to all temps environment in Various Seasonal, different regions; When the volume that utilizes fuel tank is to greatest extent once annotated more multiple fuel, can avoid fuel oil and overflow because high temperature expands.
