Description
Technical field
The utility model relates to auto parts and components, refers to the plastic fuel tank structure that a kind of hybrid power gasoline car uses particularly.
Background technology
Conventional gasoline vehicle in use driving engine can operate always, the gasoline vapors be stored in charcoal tank can be made like this can to enter manifold at any time and participate in burning and make charcoal tank clean by desorption.According to correlative study; the requirement of conventional plastic tank design is withstand voltage is about about 8kPa; and the maximum high pressure that fuel tank can be caused to produce about 20kPa of variation of ambient temperature, so the multifunction valve meeting disengaged vapor oil vapour that fuel tank is arranged is to reduce tank internal pressure thus to play the object protecting fuel tank.And this part gasoline vapors can be absorbed by the charcoal tank that desorption is clean again, thus reach the object of protection of the environment.And motor vehicle driven by mixed power there will be pure motor driving at operational process and does not use the situation of driving engine, charcoal tank desorption probability can be caused like this to decline and make the less able of charcoal tank adsorbed gasoline steam, cannot be absorbed completely by charcoal tank from the gasoline vapors of fuel tank when variation of ambient temperature and be discharged in air, causing atmospheric contamination.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology; a kind of high pressure resistant plastic fuel tank structure is provided; this structure can the pressure of resistance to more than 20kPa, thus reduce the amount that in fuel tank, gasoline vapors is got rid of from multifunction valve, reaches the object of protection of the environment.
The technical solution of the utility model is: a kind of high pressure resistant plastic fuel tank structure, comprise plastic fuel tank housing, it is characterized in that, also comprise the upper bracket and lower bracket that are connected to form respectively by many upper connecting rods and lower connecting rod, the upper connecting rod of described upper bracket is positioned at plastic fuel tank case top and along plastic fuel tank housing sidewall axially to downward-extension, the lower connecting rod of described lower bracket is positioned at plastic fuel tank housing bottom and axially upwards extends along plastic fuel tank housing sidewall, described upper connecting rod lower end and lower connecting rod upper end connect one to one, described plastic fuel tank housing indent is formed and upper connecting rod, the mounting groove that lower connecting rod is corresponding.
Preferably, described upper connecting rod lower end is provided with outside upper engaging lug, and described lower connecting rod upper end is provided with outside lower engaging lug, and described upper engaging lug, lower engaging lug are connected by bolt correspondence.
Preferably, described upper bracket is included in first support that plastic fuel tank housing bilateral symmetry is arranged.
Further, the upper stirrup by being positioned at plastic fuel tank case top between first support described connects.
Preferably, described lower bracket is included in second support that plastic fuel tank housing bilateral symmetry is arranged.
Further, the lower stirrup by being positioned at plastic fuel tank housing bottom between second support described connects.
Preferably, described plastic fuel tank housing bottom is provided with the reinforced rib caved inward.
Preferably, described plastic fuel tank housing is provided with Multifunctional high pressure valve.What Multifunctional high pressure valve adopted is high-pressure electric control electromagnetic valve; this valve integrated pressure detects and valve body is opened and closing function, i.e. the valve closing when tank internal pressure is no more than design pressure, when pressure oversteps the extreme limit pressure; valve open is vented, to protect the safety of fuel tank.
Preferably, described plastic fuel tank housing is provided with the overall reinforced rib of the bottom that caves inward, extends to vertically from top.
The beneficial effects of the utility model are:
Structure is simple, easy for installation, considerably increase the intensity of plastic fuel tank housing, actv. minimizing is discharged to the gasoline vapors amount outside fuel tank because of the change of ambient temperature, solve the sordid problem of charcoal tank desorption caused because hybrid electric vehicle crosses little use driving engine in journey, solve further because gasoline vapors too much causes charcoal tank adsorption power not enough and be discharged into the problem of environmental pollution caused in air.
