Description

An automobile fuel tank furnished with an auxiliary tank

The present invention relates to a fuel tank used in an automobile, and more particularly, an emergency fuel tank is formed in the main fuel tank to enable the fuel to run to a place where refueling is possible through the minimum stored emergency fuel while the fuel is exhausted. The present invention relates to a fuel tank for an automobile having an emergency fuel container having a condensed structure in which fuel is filled or discharged.

In general, automobiles are designed and manufactured with the proper volume so that a certain volume of fuel can be put in a fuel tank so that a certain distance can be operated without refueling.

The volume of the fuel tank is made in various ways depending on the type of vehicle, fuel economy, and the like.

However, the conventional fuel tank is composed of a single tank, and when the fuel filled in the single tank is exhausted, the operation becomes impossible.

Increasing the capacity of fuel tanks or installing more than one of these fuel tanks may be an alternative to exhausting fuel, but it is not necessary for fuel consumption due to the excessive load weight for virtually any automobile except for some special vehicles or heavy trucks. Problems such as worsening can occur.

Of course, it is possible to prevent fuel exhaustion if the fuel is replenished habitually, but this problem occurs suddenly because the fuel gauge generally refuels when the fuel reaches the lower limit of the fuel.

In order to solve the above problems, there have been various proposals.

According to the prior arts previously applied, the fuel tank and the auxiliary fuel tank were separately installed and connected to the fuel line, and the auxiliary fuel tank was installed inside the fuel tank, which will be described in detail.

The auxiliary fuel tank for automobiles of Korean Patent Laid-Open Publication No. 1999-40119 has a discharge pipe which branches the auxiliary pipe in the middle of the fuel injection pipe, forms an auxiliary fuel tank in the branched auxiliary pipe, and is connected to the fuel injection pipe on the lower surface of the auxiliary fuel tank. Forming a but is made by forming an open-close valve in the middle of the discharge pipe.

When fuel is injected into the main fuel tank, the auxiliary fuel tank is filled with fuel, and if necessary, the fuel of the auxiliary fuel tank is used. There is a problem that is not easy, because the fuel flows in accordance with the inclination of the fuel injection pipe has a very large disadvantage of the installation site.

On the other hand, the emergency auxiliary fuel tank of the Republic of Korea Utility Model No. 1998-12517 vehicle is connected to the auxiliary fuel tank between the fuel tube assembly and the delivery pipe of the main fuel tank and the amount of fuel exceeded from the delivery pipe by the control of the ECU auxiliary fuel tank It is configured to be used for emergency refueling after recovery and storage.

The proposal is to recover the excess fuel on the fuel supply line from the fuel tank to the injector of the engine to the auxiliary fuel tank and to drain the fuel over the auxiliary fuel tank to the main tank when the fuel is insufficient. It is intended to be used.

This is because the auxiliary fuel tank is located in the fuel line supplied from the fuel tank to the injector, which is also not easy to install and there is a problem that fuel leakage may occur when an accident occurs because fuel remains in the line.

On the other hand, in the case of the Republic of Korea Patent Publication No. 97-65067, Korean Utility Model No. 95-11253, the main fuel tank and the auxiliary fuel tank are separately installed and installed, and the flow path connecting the two fuel tanks, and the blocking to open and close the flow path There is a thing formed by forming a valve.

Since substantially two fuel tanks are separated, a problem arises in that the mounting space is required to be larger than the same capacity depending on the vehicle, thereby reducing the space usage efficiency.

On the other hand, there has been a proposal to install an auxiliary tank by dividing the space inside the fuel tank. Most of the cars are located on an inclined surface, so that the fuel supply is stopped when the fuel tank does not have much fuel remaining due to the slope. will be.

Among them, the chamber structure of the automobile fuel tank of Korean Patent Application Laid-Open No. 1998-76627 is made for the stability of fuel supply on the ramp, and the fuel supply of the auxiliary chamber is allowed to flow into the chamber in the fuel tank on the inclined surface to stop the fuel supply. An opening and closing device is formed between the auxiliary chamber and the chamber by a mouth (knit) to prevent it. According to this technique, the supply of fuel at the slope is prevented, but it is far from securing emergency fuel due to the exhaustion of the fuel tank.

The present invention has been made to solve all the problems of the prior art as described above has the same purpose.

The present invention is to provide an automotive fuel tank having an emergency fuel tank to form an emergency fuel container inside the fuel tank of the vehicle, to store a predetermined fuel for emergency by oiling, and to open and use the emergency fuel container when necessary. .

The present invention is to provide a fuel tank for an automobile having an emergency fuel container with excellent installation space efficiency and no worry of leakage because it does not occupy a separate installation space because the position to form the emergency fuel container in parallel in the fuel tank.

The present invention is to provide a fuel tank for a vehicle having an emergency fuel container is excellent in safety and easy to use and non-powered by forming a configuration for opening and closing the fuel of the emergency fuel container in the fuel inlet port.

The present invention to achieve the above object is formed by partitioning the emergency fuel tank of a constant capacity inside the main fuel tank, to form a valve assembly that can be opened and closed on one side of the fuel tank, the opening and closing device for opening and closing the valve assembly inside the fuel inlet It is formed in the connection to the filling port plate by connecting with a cable.

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

The present invention partitions the emergency fuel container 20 to store a certain amount of fuel in the inner portion of the main fuel tank 10.

The upper portion of the emergency fuel tank 20 is formed by puncturing the inlet 21 of the appropriate size so that the fuel can enter, and the opening and closing valve 23 is formed in the lower portion.

The opening and closing valve is preferably made to be opened and closed operation by a non-powered opening and closing device. This is to use the existing structure rather than processing the outside of the existing fuel tank to reduce the durability.

Therefore, the on-off valve 23 is closed with the fuel outflow by the spring force, and when the external force exceeding the spring force is applied, the valve 25 is coupled to the switch 30 coupled with the cable 25 to open the valve.

The opening and closing device 30 is installed by using a normal oil filling port 50 diaphragm 53 and an oil filling plate 51.

The oil hole 50 is formed by drilling a hole 31 in one end of the perforated plate 53 and a hole 32 in communication with the hole, and is provided to be supported on the hole and the hole 31 and 32. The cable 25 is fixed to the lower portion of the lever 33 is formed, and the other end of the cable is coupled to the on-off valve 23 by a valve operating force.

On the other hand, the filling hole plate 51 is formed by coupling to contact the cable 23 by providing a rotating end 51b bent and extended from the hinge 51a of the filling hole plate 51 to open and close the filling hole 50. It is made so that the cable 23 can be pushed outward when the filling plate 51 rotates.

In addition, the on-off valve 23 is a valve body 231 capable of introducing fuel and a valve 233 which is supported by a spring 232 inside the body and closes the discharge hole and fixes the body to the emergency fuel container 20. It consists of a fixing nut 234 and the end of the cable 25 is fixed to the valve 233.

Of course, the fuel container 20 is formed in the inclined surface to form a bottom surface to be discharged without any residue in consideration of the minimum oil for refueling in the emergency and the on-off valve also flows down the foreign matter flows smoothly valve operation It would be desirable to configure it to be made.

Unexplained reference numeral 59 denotes an oil filling cap and 60 denotes an oil filling machine.

The cable 25 of the opening and closing device 30 of the present invention is embedded along the fuel inlet line formed in the existing main fuel tank 10.

When the fuel is injected into the main fuel tank 10, the present invention fills the fuel through the inlet hole 21 while the oil surface exceeds the upper surface of the emergency fuel container 20 as illustrated in FIG. 2.

Even when the fuel is consumed by the use of a vehicle and the fuel oil level of the main fuel tank 10 is lowered, the fuel inside the emergency fuel tank 20 is maintained as it is.

When unexpected fuel exhaustion occurs in such a state, when the user opens the fuel filling port and pulls the lever 33 formed in the filling hole diaphragm 53 over the long hole 32, the valve 233 of the opening / closing valve 23 opens. The fuel is discharged into the main fuel tank in the emergency fuel container 20 and the driving of the vehicle is continuously guaranteed.

As described above, the emergency fuel tank 20 is enough to emergencyly hold approximately 2 to 3 liters of fuel in consideration of the distance between the gas station of the highway and it is obvious that the capacity can be increased or decreased according to the situation.

When operating with the emergency fuel, the user will find a gas station at the shortest distance and refuel.

At this time, the open on-off valve 23 can be stored in the fuel for the next use only when moved to the closed position, but if the reverse operation is performed manually, the reverse operation may be lost by the user's mistake, and In conjunction with each other, the valve is closed.

Therefore, when the lubricator 60 is inserted into the oil inlet 50, the oil inlet plate 51 is pushed and rotated while the pivoting end 51b of the oil inlet plate 51 pushes the cable 23 and is positioned at the long hole 32. Since the cable 33 is pushed out and placed in the opening 31, the cable 23 is displaced and the valve 233 is automatically closed as the cable is pulled by the action of the spring 232 of the on-off valve 23.

Thus, the valve of the emergency fuel tank opened by the oiling process is reversed and closed.

After that, refueling and replenishment of the emergency fuel container are made and the above operation is repeated.

Next look at another embodiment of the opening and closing device of the present invention.

Reference is made to FIGS. 6 to 8.

Opening and closing device (30a) is provided with a ring-shaped cable insertion hole 311 for fitting the cable 25, the lower portion is wide open to form a hinge installation hole 315 and the hinge surface 316 coupled to the hinge 317 The link plate 310 is formed by providing an opening 313 through which the lower plate is cut.

The rotating surface 51b of the oil filling plate 51 is coupled to the contact surface 316 of the link plate 310.

The link plate 310 is rotatably fastened to the fixing bracket 320 formed in the diaphragm 53 through the hinge installation hole 315.

According to another embodiment described above it may be easier to push the cable to move the position.

That is, the cable is inserted into the cable insertion hole 311 of the link plate 310 is coupled to the lever 33.

As described above, when the fuel is exhausted in the main fuel tank 10 and the opening and closing valve 23 of the emergency fuel tank 20 is opened, pull the lever 33 to open the valve 25 and the lever to the long hole 32. Position is made as shown in FIG.

Then, when fueling is performed, as shown in FIG. 8, as the oil inlet plate 51 rotates, the pivoting end 51b of the oil inlet plate rotates around the hinge 51a to contact the contact surface 316 of the link plate 310. At this time, the link plate is rotated around the hinge 315a and rotated at the link 317 so that the cable insertion hole 311 formed in the upper portion pushes the cable 25 to open the lever 33 located in the long hole 32. It is to position 31 to close the on-off valve 23.

The opening 313 is incised to eliminate operational interference with the cable 25.

This modified embodiment is to induce a smooth operation because the mechanical friction in the reverse operation of the lever 33 is minimized.

The mechanical operation of the reverse operation of the cable is one example that can be most preferably selected in consideration of the reliability of the electric device, the trouble of installation, and the relationship with the combustible fuel. The degree of changing to a mechanical structure of one or other type is only very easy by the claims described in the present invention.

According to the present invention as described in detail above, by forming an emergency fuel tank inside the fuel tank of the vehicle, the fuel tank is formed by storing a certain fuel for emergency use by refueling and opening the emergency fuel tank when necessary. There is no hassle to separate more than one, and a fuel tank of essential capacity is formed in one fuel tank, so it is easy to install and maintain while having the effect of emergency operation when the fuel is exhausted.

In addition, since the location of forming the emergency fuel container is parallel to the inside of the fuel tank, it does not occupy a separate installation space, so the installation space efficiency is excellent, there is no fear of leakage, and a structure for opening and closing the fuel of the emergency fuel container is formed at the fuel inlet. Since it is made to interlock with the fuel injection is a very practical design with the effect that it is easy to use and the safety can be guaranteed in a non-powered manner.
