Abstract
The utility model relates to a water board for a plastic fuel tank and belongs to the technical field of the fuel tank. The water board for the plastic fuel tank comprises two substrates and a connection plate, wherein the two substrates are horizontally arranged; the connection plate is positioned between the two substrates; the two substrates are connected into one whole body by the connection plate; both upper and lower surfaces of the substrates are respectively provided with a plurality of crossed longitudinal fins and transverse fins; both the longitudinal fins and the transverse fins extend along the direction vertical to the substrates; the upper end faces of the substrates are provided with a plurality of upper rivets; the top ends of the upper rivets are welded on the top wall of the fuel tank; the lower end faces of the substrates are provided with a plurality of lower rivets; the lower ends of the lower rivets are welded on the bottom wall of the fuel tank; and the substrates are provided with a plurality of strip longitudinal grooves and transverse grooves. The water board has a firm structure. The dropping phenomenon cannot be generated. Both the upper and lower surfaces of the substrates are respectively provided with the longitudinal fins and the transverse fins, which extend along the height direction, so that a plurality of obstacles are generated to fuel in both longitudinal and transverse directions. The water board has a good effect of reducing noise.
Description
Technical field
The utility model relates to the washboard that a kind of plastic fuel tank is used, and belongs to the fuel tank technical field.
Background technology
Along with the lifting day by day that people require the entire car noise, the noise that the inner fuel oil of car fuel tank when starting or brake rocks generation has been subjected to increasing concern.The reason that the fuel tank noise produces be vehicle start suddenly or during brake inner fuel oil because due to the inertial impaction fuel tank upper wall surface.
A lot of vehicles have increased the washboard of different modes for the noise that reduces fuel tank.The effect of washboard is to increase together in the direction that fuel oil rocks to hinder, and cuts down fuel oil and rocks the energy of generation, thereby play the effect that reduces noise.
The design of washboard in the market mainly is to increase the choked flow structure at fuel tank internal, roughly is divided into following two kinds:
(1) common blowing washboard structure increases muscle or recessed thorax structure and rocks the noise of generation to reduce fuel oil on the fuel tank housing, it is more general to reduce noise result.
(2) built-in build-up type washboard, the height of the height of washboard and width and fuel tank and width are suitable and be provided with spring, before assembling, from the oil pump mouth washboard is put length of spring compressed into fuel tank internal, open spring after locating, the washboard top and the bottom position by inner structure, washboard is generally flats, is hung vertically in box house.This scheme is very high to matching requirements and consistency of product requirement, and because of area is bigger, the impulsive force that is subjected to is also bigger, is dropping easily after repeatedly impacting, and stability is poor.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, the washboard that provides a kind of plastic fuel tank to use, Stability Analysis of Structures and excellent noise reduction effect.
For solving above technical matters, the washboard that a kind of plastic fuel tank provided by the utility model is used, comprise two horizontally disposed substrates and the connecting panel that between two substrates, two substrates is connected as a single entity, the upper and lower surface of described substrate is respectively equipped with cross one another longitudinal rib of multiple tracks and transversal rib, and described longitudinal rib and transversal rib all extend along the direction perpendicular to described substrate; Be distributed with a plurality of rivets of going up on the upper surface of described substrate, described top of going up rivet is welded on the roof of fuel tank; Be distributed with a plurality of rivets down on the lower surface of described substrate, the described lower end of rivet down is welded on the diapire of fuel tank.
With respect to prior art, the utility model has been obtained following beneficial effect: substrate is horizontally disposed with, and its upper and lower surface is welded on the box body wall by last rivet and following rivet respectively, makes that whole washboard structure is very firm, obscission can not occur; And the upper and lower surface of substrate is respectively equipped with longitudinal rib and the transversal rib that extends along short transverse, all fuel oil is produced multiple tracks at vertical and horizontal and hinders excellent noise reduction effect.
As preferred version of the present utility model, described substrate is provided with the longitudinal fluting and the transverse concave groove of multiple tracks strip.Longitudinal fluting and transverse concave groove can improve the intensity of substrate, and the motion of fuel oil is also had certain shock damping action.
Description of drawings
Fig. 1 is the front view of the utility model washboard.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the block diagram of Fig. 1.
Among the figure: 1 substrate; 2 connecting panels; Rivet on 3; 4 times rivets; 5 longitudinal ribs; 6 transversal ribs; 7 longitudinal flutings; 8 transverse concave grooves.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the washboard that the utility model plastic fuel tank is used comprises that substrate 1 and 2, two substrates 1 of connecting panel are horizontally disposed with, and connecting panel 2 is connected as a single entity two substrates between two substrates.Substrate 1 is provided with the longitudinal fluting 7 and the transverse concave groove 8 of multiple tracks strip, and connecting panel 2 is set to arch according to the shape of fuel tank.The upper and lower surface of substrate 1 is respectively equipped with cross one another longitudinal rib 5 of multiple tracks and transversal rib 6, and longitudinal rib 5 and transversal rib 6 all extend along the direction perpendicular to substrate 1; Be distributed with a plurality of rivets 3 of going up on the upper surface of substrate 1, the top of last rivet 3 is welded on the roof of fuel tank; Be distributed with a plurality of rivets 4 down on the lower surface of substrate 1, the lower end of following rivet 4 is welded on the diapire of fuel tank.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
Claims (2)
1. washboard that plastic fuel tank is used, it is characterized in that: comprise two horizontally disposed substrates and the connecting panel that between two substrates, two substrates is connected as a single entity, the upper and lower surface of described substrate is respectively equipped with cross one another longitudinal rib of multiple tracks and transversal rib, and described longitudinal rib and transversal rib all extend along the direction perpendicular to described substrate; Be distributed with a plurality of rivets of going up on the upper surface of described substrate, described top of going up rivet is welded on the roof of fuel tank; Be distributed with a plurality of rivets down on the lower surface of described substrate, the described lower end of rivet down is welded on the diapire of fuel tank.
