Abstract
The utility model discloses a car fuel tank, the housing comprises an upper housing and a lower housin, down the casing hangs assembly relatively fixed after with, the upper portion of going up the casing is equipped with the breather pipe, breather pipe UNICOM go up casing and atmosphere, the right -hand member of going up casing upper portion is equipped with into oil pipe, enter oil pipe UNICOM go up casing and nozzle, the breather pipe stretches into the position of the internal tip of epitheca is higher than it stretches into to advance oil pipe the position of the internal tip of epitheca. The safe distance that oil pipe hung after with has been guaranteed to advance to solved and advanced oil pipe and arrange the problem of regurgitating of refueling when last casing.
Description
Technical field
The utility model relates to automotive field, particularly a kind of fuel tank of vehicle.
Background technology
At present, after meeting manned vehicle, touch legislative control on safety requirement, fuel tank is arranged in rear-mounted front.When fuel filler pipe assembly is connected to fuel tank from oil filling port, rear-mounted can be crossed over.And oil inlet is when being arranged in the upper shell of fuel tank, oil inlet position, higher than breather pipe, is caused liquid level first to flood breather pipe end but is not flooded oil inlet end.Like this, fuel tank internal pressure rises, and have portion gas, under fuel tank internal high pressure, the fuel oil in oil inlet is pressed out to oil filling port, nozzle jumps rifle after sensing this part fuel oil automatically, but this part fuel oil can overflow oil filling port causes oiling to regurgitate phenomenon.
Summary of the invention
The utility model is to solve deficiency of the prior art, provides one and ensure that oil inlet and rear-mounted safety distance, and the fuel tank of vehicle of problem is regurgitated in the oiling solved when oil inlet is arranged in upper shell.
The technical scheme of a kind of fuel tank of vehicle of the utility model is:
A kind of fuel tank of vehicle, comprise upper shell and lower house, formed between described upper shell and described lower house and hold oil pocket, described lower house is relative with rear suspension assembly fixing, the top of described upper shell is provided with the breather pipe stretched in described upper shell, oil pocket and air is held described in described breather pipe UNICOM, the right-hand member on described upper shell top is provided with the oil inlet stretched in described upper shell, oil pocket and nozzle is held described in described oil inlet UNICOM, the position that described breather pipe extend into the end in described upper shell extend into the position of the end in described upper shell higher than described oil inlet.
The technical scheme of a kind of fuel tank of vehicle of the utility model can also be:
Described breather pipe is arranged in described appearance oil pocket with extending into parts transversely in described upper shell.
The partial arc that described oil inlet extend in described upper shell bends and arranges downward vertically.
A kind of fuel tank of vehicle of the utility model, comprise upper shell and lower house, formed between described upper shell and described lower house and hold oil pocket, described lower house is relative with rear suspension assembly fixing, the top of described upper shell is provided with the breather pipe stretched in described upper shell, oil pocket and air is held described in described breather pipe UNICOM, the right-hand member on described upper shell top is provided with the oil inlet stretched in described upper shell, oil pocket and nozzle is held described in described oil inlet UNICOM, the position that described breather pipe extend into the end in described upper shell extend into the position of the end in described upper shell higher than described oil inlet.Like this, lower house is relative with rear suspension assembly fixing, and oil inlet is arranged on upper shell, ensure that the safety distance of oil inlet and rear suspension assembly.And the end position being arranged on the breather pipe of upper shell inside is higher than the end position of oil inlet being arranged on upper shell inside, like this, in the refueling process of nozzle, fluid enters in the appearance oil pocket of fuel tank, the gas held in oil pocket is discharged by breather pipe, first fluid flood the end of oil inlet in upper shell, at this moment, fluid is had in fuel filler pipe, and continue to fuel tank fuel feeding, when fluid floods the end of breather pipe in upper shell, owing to holding the effect of oil pocket internal gas pressure, fluid can not enter into again and hold in oil pocket, the fluid that retains in oil inlet is increased, after being increased to the inductive switch having touched nozzle, refuel and stop.Like this, avoid breather pipe and be first submerged and hold air pressure in oil pocket and promote the phenomenon that fluid flows back to oil inlet, problem is regurgitated in the oiling solved when oil inlet is arranged in upper shell.

Detailed description of the invention
Below in conjunction with specific embodiment, a kind of fuel tank of vehicle of the present utility model is further described.
As shown in Figure 1, a kind of fuel tank of vehicle, comprise upper shell 1 and lower house 2, described lower house 2 is relative with rear suspension assembly fixing, the top of described upper shell 1 is provided with breather pipe 3, upper shell 1 and air described in described breather pipe 3 UNICOM, and the right-hand member on described upper shell 1 top is provided with oil inlet 4, upper shell 1 and nozzle described in described oil inlet 4 UNICOM, the position that described breather pipe 3 extend into the end in described upper shell 1 extend into the position of the end in described upper shell 1 higher than described oil inlet 4.Like this, lower house 2 is relative with rear suspension assembly fixing, and oil inlet 4 is arranged on upper shell 1, ensure that the safety distance of oil inlet 4 and rear suspension assembly.And the end position being arranged on the breather pipe 3 of upper shell 1 inside is higher than the end position of oil inlet 4 being arranged on upper shell 1 inside, like this, in the refueling process of nozzle, fluid enters in the appearance oil pocket of fuel tank, the gas held in oil pocket is discharged by breather pipe 3, first fluid flood the end of oil inlet 4 in upper shell 1, at this moment, fluid is had in fuel filler pipe, and continue to fuel tank fuel feeding, when fluid floods the end of breather pipe 3 in upper shell 1, owing to holding the effect of oil pocket internal gas pressure, fluid can not enter into again and hold in oil pocket, the fluid that retains in oil inlet 4 is increased, after being increased to the inductive switch having touched nozzle, refuel and stop.Like this, avoid breather pipe 3 and be first submerged and hold air pressure in oil pocket and promote the phenomenon that fluid flows back to oil inlet 4, problem is regurgitated in the oiling solved when oil inlet 4 is arranged in upper shell 1.
See accompanying drawing 1, a kind of fuel tank of vehicle of the present utility model on the basis of technique scheme, Ke Yishi: described breather pipe 3 is arranged in described appearance oil pocket with extending into parts transversely in described upper shell 1.Like this, for the gas in fuel tank arranges the horizontal discharge path of stream, gas uniform speed can be controlled and discharge.Preferred technical scheme can be further: the partial arc that described oil inlet 4 extend in described upper shell 1 bends and arranges downward vertically.Like this, the setting that circular arc is bending is convenient to fluid and is entered into oil inlet 4 smoothly, and setting is downward vertically adapted to the fluid flowed out downwards, avoids fluid when flowing in fuel tank and the bottom splashing of directly clashing into and causing and the large sound.
Above-mentionedly only a kind of specific embodiment in the utility model to be illustrated; but can not as protection domain of the present utility model; every according to the change of the equivalence done by design spirit in the utility model or modification, all should think and fall into protection domain of the present utility model.
