Description
Technical field
A kind of oil pump the utility model is related to Explosion suppression oil tank protects structure, belongs to vehicle feed system technical field.
Background technology
The top red flag car HQE series V501 vehicles of one vapour independent development, because of starting using 4.0L/6.0L discharge capacities
Machine, volume of fuel tank reach more than 100L, lead to it in the case where Fuel Oil Remaining is less, fuel vapor in fuel tank content mistake
Height, when ambient temperature steeply rises, fuel tank increases aluminium alloy web-like there are the risk that high temperature explodes in fuel tank
Explosion-suppressing material.
For explosion-suppressing material in fuel tank is avoided to influence the movement of oil pump and float, while ensure explosion-suppressing material and its production in fuel tank
Raw impurity will not have an impact the use of oil pump, need to design a kind of oil pump protection structure of Explosion suppression oil tank.
Utility model content
The utility model aim is to provide a kind of oil pump protection structure of Explosion suppression oil tank, can ensure datonation-inhibition material in fuel tank
Material and its impurity generated, will not have an impact the use of oil pump.
The utility model solves technical problem and adopts the following technical scheme that：A kind of oil pump protection structure of Explosion suppression oil tank,
Including shield upper shell, shield lower housing and support plate；
The shield upper shell is fixed on fuel tank upper shell, and Open Side Down for the shield upper shell, the shield
The lower end of cover upper shell turns down outward, forms the first folding portion；
Shield lower housing is fixed on fuel tank lower housing, the opening upwards of the shield lower housing, and is inserted into the shield
In the opening of upper shell；
The lower end of the support plate is fixed on the shield lower housing, and upper end turns down outward, forms the second folding portion；
Gap is formed between the shield upper shell and shield lower housing, is had between the first folding portion and the second folding portion
There is gap.
Optionally, the gap between the shield upper shell and shield lower housing is the 5%-10% of explosion-suppressing material diameter.
Optionally, the gap between the first folding portion and the second folding portion is the 5%-10% of explosion-suppressing material diameter.
Optionally, the upper edge of shield lower housing is higher 15mm-20mm than shield upper shell lower edge.
Optionally, first folding portion is parallel with the second folding portion.
Optionally, the shield upper shell and shield lower housing on be formed with multiple through-holes, the diameter of the through-hole is big
Small is 7 ± 1mm.
The utility model has the advantages that：The Explosion suppression oil tank of the utility model oil pump protection structure effectively, fill
It protects the working performance of oil pump with dividing, under the premise of fuel tank datonation-inhibition function is fully ensured that, solves Explosion suppression oil tank filling material
Interference relationship between material and oil pump, while effectively prevent in the space where the impurity that explosion-suppressing material generates enters oil pump,
Achieve the purpose that oil pump is protected.
Description of the drawings
Fig. 1 is that the oil pump of the Explosion suppression oil tank of the utility model protects the structure diagram of structure；
Fig. 2 is the structure diagram in A portions in Fig. 1；
The mark in the figure shows：1- shield upper shells；2- shield lower housings；3- support plates；4- fuel tank upper shells；5- fuel tanks
Lower housing；6- explosion-suppressing materials.
Specific embodiment
The technical solution of the utility model is further elaborated with reference to embodiment and attached drawing.
Embodiment 1
A kind of oil pump protection structure of Explosion suppression oil tank is present embodiments provided, including shield upper shell 1, shield lower housing 2
And support plate 3.
The shield upper shell 1 is welded on fuel tank upper shell 4, and Open Side Down for the shield upper shell；Shield
Lower housing 2 is welded as a whole with support plate 3, and by integral solder on fuel tank lower housing 5, and oil pump is located on the shield at this time
In the space that housing 1 and shield lower housing 2 are enclosed, explosion-suppressing material 6 is located at 2 institute of the shield upper shell 1 and shield lower housing
The outside of enclosing.
The lower end of the shield upper shell 1 turns down outward, the first folding portion of formation, under the shield upper shell 1 and shield
Gap delta is formed between housing 2, moreover, the lower openings of the shield upper shell 1 are inserted into the upper end of the shield lower housing 2,
And so that the upper edge of shield lower housing 2 is higher 15mm-20mm than 1 lower edge of shield upper shell.
By being fixedly welded on the shield lower housing, upper end turns down outward for the lower end of the support plate 3, forms second
Folding portion, first folding portion is parallel with the second folding portion, and has gap between the first folding portion and the second folding portion
δ。
It is further preferred that the gap delta for explosion-suppressing material 6 diameter 5%-10% so that explosion-suppressing material and its
The disintegrating slag of generation can not almost enter the inside in space that shield upper shell 1 is enclosed with shield lower housing 2, therefore this practicality
The novel working performance for effectively, fully protecting oil pump, under the premise of fuel tank datonation-inhibition function is fully ensured that, solves datonation-inhibition
Interference relationship between fuel tank packing material and oil pump, while the impurity for effectively preventing explosion-suppressing material generation enters where oil pump
Space in, achieved the purpose that oil pump protect.
In the present embodiment, be formed with multiple through-holes on the shield upper shell and shield lower housing, the through-hole it is straight
Diameter size is 7 ± 1mm, reaches the 5%-10% of the diameter of explosion-suppressing material 6, so that fuel oil can be entered by the through-hole
Space between the shield upper shell and shield lower housing, and disintegrating slag caused by explosion-suppressing material 6 can not be by described logical
Hole enters the space between the shield upper shell and shield lower housing.
The sequencing of above example is not only for ease of description, represent the quality of embodiment.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It still can modify to the technical solution recorded in foregoing embodiments or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
