Description
[ technical field ]
The utility model belongs to the technical field of the automobile parts technique and specifically relates to a built-in unrestrained plate structure of fuel tank.
[ background art ]
At present, with the technological innovation of vehicle energy structure, power transmission and other aspects, such as the popularization of hybrid electric vehicles, the noise intensity of traditional noise sources such as engines and exhaust systems is continuously reduced, the shaking noise of fuel tanks is more and more obvious, and the shaking noise of fuel tanks is also one of important indexes for measuring the comfort level of vehicles. The design of the built-in anti-surge plate of the fuel tank is an effective means for reducing the shaking noise of the fuel tank.
[ contents of utility model ]
The utility model aims at solving foretell not enough and providing a built-in unrestrained plate structure of fuel tank, can reduce the fuel and rock the noise, and under the prerequisite of realizing equal noise reduction effect, its volume is littleer, and structural strength is higher, installs more reliable and more stable.
Design a built-in wave plate structure of fuel tank for realizing above-mentioned purpose, including breakwater body 1, wave bar 2, welding muscle 3, breakwater body 1 is the S type, adopt the arc transition between 1 left part of breakwater body and the right part, it has wave bar 2 to distribute in the breakwater body 1, wave bar 2 is the rhombus latticed wave bar, the rhombus latticed wave bar is cut apart into rhombus subregion with the surge in the fuel tank, be provided with welding muscle 3 on the breakwater body 1, welding muscle 3 is used for and fuel tank welded fastening, welding muscle 3 is sharp array by trapezoidal flat board and distributes and form.
Further, the trapezoidal flat plate of welding muscle 3 is right trapezoid flat plate, trapezoidal flat plate is provided with at least three and parallel array and arranges, the right-angle side welding of trapezoidal flat plate is on breakwater body 1.
further, welding rib 3 contains and transversely is cascaded distribution, the downside all is provided with welding rib 3 on the breakwater body 1.
Further, the periphery of the breakwater body 1 is in a smooth transition type.
Compared with the prior art, the utility model, can reduce the fuel and rock the noise, and under the prerequisite that realizes equal noise reduction effect, the utility model discloses the volume is littleer (less than 20% of plate breakwater); and simultaneously, the utility model discloses welded structure is reasonable, the oil tank welding of being convenient for, and structural strength is higher, installs more reliable and more stable, is worth popularizing and applying.
[ description of the drawings ]
Fig. 1 is a schematic structural diagram of the present invention;
Fig. 2 is a functional structure detail schematic diagram of the present invention;
In the figure: 1. the corrugated board comprises a corrugated board body 2, a corrugated rib 3, a welding rib a, a rhombic grid type corrugated rib b, a linear array type trapezoidal flat plate welding rib c, a stepped welding rib distribution mode d and a trapezoidal welding rib distribution mode.
[ detailed description of the invention ]
The invention is further described below with reference to the accompanying drawings:
as shown in the attached drawing 1, the utility model discloses a wave breaker body 1, wave breaker 2, welding muscle 3, wave breaker body 1 is the S type, the rounding off type is adopted to wave breaker body 1 periphery, adopt the arc transition between 1 left part of wave breaker body and the right part, it has wave breaker 2 to distribute in the wave breaker body 1, wave breaker 2 is the net unrestrained muscle of rhombus, the rhombus subregion is cut apart into with the surge in the fuel tank to the net unrestrained muscle of rhombus, be provided with welding muscle 3 on the wave breaker body 1, welding muscle 3 is used for and fuel tank welded fastening, welding muscle 3 is sharp array by trapezoidal flat board and distributes and form. The trapezoidal flat plate of the welding rib 3 is a right-angle trapezoidal flat plate, at least three trapezoidal flat plates are arranged in parallel in an array mode, and right-angle edges of the trapezoidal flat plates are welded on the surfboard body 1; the welding rib 3 transversely contains and is cascaded distribution, and the downside all is provided with welding rib 3 on the breakwater body 1. The distribution mode of the wave-proof ribs is a key factor for blocking, differentiating and offsetting surge kinetic energy, and the arrangement of the welding ribs is related to the bearing capacity of surge impact energy, the stability of products and the service life.
As shown in fig. 2, the rhombic grid type wave-proof rib a can divide the surge into rhombic small areas, and four strands of liquid flows which are offset to the center are formed on the small inclined planes of the rhombic grid side lines through reflection, so that the impact on the wave-proof plate is reduced while the kinetic energy of the surge is reduced; the linear array type trapezoidal flat plate welding ribs b have excellent welding strength and supporting structure strength, and can ensure the reliability of welding and the connection strength with the wave-proof plate; the step-shaped welding rib distribution mode c and smooth transition enable the shock resistance of the breakwater to be improved by 50% compared with that of a linear type breakwater; trapezoidal formula welding muscle distribution mode d deals with the surge impact force of co-altitude not and is the distribution of inverted triangle proportion, and the distribution of welding muscle accords with the distribution law of impact force, and the structure is retrencied and can satisfy the user demand again.
The present invention is not limited by the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and are all included in the protection scope of the present invention.
