[0036] According to a first aspect of the utility model, there is provided an oil tank having a noise reduction function, such as Figures 1 to 7 As shown, the oil tank with noise reduction function can be used in hybrid new energy vehicles. The oil tank with noise reduction function includes a shell 1, a peripheral wave-breaking plate group and a middle wave-breaking plate group.

[0037] In the following description, reference will be made to Figures 1 to 7 The detailed structures of the shell 1, the peripheral wave-breaking plate group and the middle wave-breaking plate group of the oil tank with noise reduction function are described in detail. Figure 1 and Figure 2The shell 1 in the figure is half of the entire oil tank shell, and the wave-breaking plates are installed on the part of the shell 1 shown in the figure, and the other half of the shell 1 is not installed with the wave-breaking plate assembly. When the oil tank is assembled as a whole, the other half of the shell 1 without the wave-breaking plates installed can be directly buckled and fixed to the shell 1 shown in the figure, and the fixing method can be, for example, using fastening bolts.

[0038] like Figure 1 and Figure 2 As shown, in the embodiment, the circumferential wave-breaking plate group is arranged on the inner wall of the shell 1, and the middle wave-breaking plate group is arranged inside the circumferential wave-breaking plate group. The circumferential wave-breaking plate group can effectively reduce the noise generated by the oil in the tank hitting the side wall of the tank, and the middle wave-breaking plate group can effectively reduce the noise generated by the oil hitting the upper and lower side walls of the tank due to shaking. At the same time, the setting positions of the circumferential wave-breaking plate group and the middle wave-breaking plate group are arranged according to the actual liquid shaking points. The cooperation between the two can minimize noise, improve NVH performance, and enhance user experience.

[0039] Specifically, the peripheral wave-breaking plate group includes a first wave-breaking plate portion 2, a second wave-breaking plate portion 3 and a third wave-breaking plate portion 4. The first wave-breaking plate portion 2 is arranged at the first end of the shell 1, and the second wave-breaking plate portion 3 and the third wave-breaking plate portion 4 are arranged on both sides of the interior of the shell 1. The first end of the shell 1 is Figure 2 At the left end of the middle shell 1, the second wave-breaking plate portion 3 and the third wave-breaking plate portion 4 are arranged opposite to each other. Figure 2 The upper and lower sides of the middle shell 1, the first end of the shell 1 is Figure 2 The right end of the middle shell 1. The first wave-breaking plate portion 2, the second wave-breaking plate portion 3 and the third wave-breaking plate portion 4 can effectively reduce the noise generated by the oil hitting the side wall of the shell 1. The middle wave-breaking plate group includes a vertical plate portion 5 and a connecting plate portion 6, the vertical plate portion 5 extends from the first end of the shell 1 toward the center of the shell 1, and the connecting plate portion 6 extends from the center of the shell 1 toward the second end of the shell 1. The vertical plate portion 5 and the connecting plate portion 6 can effectively reduce the oil sloshing at the center of the shell 1.

[0040] The fuel tank with noise reduction function can be used in new energy vehicles such as hybrid electric vehicles. Since users use the pure electric mode more often, the liquid in the fuel tank will shake and hit the inner wall of the fuel tank during driving, thereby generating noise. In this way, the specially designed wave-breaking plate structure can break up the shaking liquid and reduce the shaking, and can also effectively divert the liquid, thereby achieving all-round wave protection inside the shell 1, thereby reducing noise and improving NVH.

[0041] Preferably, if Figures 1 to 3 , Figure 6 and Figure 7As shown, in the embodiment, the combined plate portion 6 may include a cover plate 601, a first vertical plate 602 and a toothed plate 603. The first vertical plate 602 and the toothed plate 603 are both arranged on the side of the cover plate 601 facing the shell 1, and the cover plate 601 is arranged between the second anti-wave plate portion 3 and the third anti-wave plate portion 4. Specifically, the first vertical plate 602 may be formed as a long strip-shaped structural plate with a plurality of openings, a first end of the first vertical plate 602 is fixedly connected to the cover plate 601, and the other end is close to the shell 1 of the oil tank, and the first vertical plate 602 can effectively break up the oil, thereby reducing the sloshing of the liquid. The toothed plate 603 can be formed as a long strip-shaped structural plate with serrations. The toothed plate 603 is arranged on the side of the first vertical plate 602. The toothed plate 603 can first break up the oil with large waves, and then the first vertical plate 602 can further break up the oil waves. The cover plate 601 can cooperate with the first vertical plate 602 to break up the horizontal and vertical oil waves in all directions. At the same time, due to the large coverage area of ​​the cover plate 601, the diversion efficiency can be further improved. In this way, the combination plate part 6 can realize effective wave protection in the middle part of the shell 1 and the second end of the shell 1, thereby reducing noise.

[0042] Preferably, if Figures 1 to 3 , Figure 6 and Figure 7 As shown, in the embodiment, the number of toothed plates 603 is multiple, and the multiple toothed plates 603 are arranged at intervals on the cover plate 601, and the length of the toothed plates 603 is less than the length of the first vertical plate 602. The number of toothed plates 603 in the embodiment is two, and the two toothed plates 603 are arranged at intervals. Since the number of toothed plates 603 is large and the length is shorter than that of the first vertical plate 602, the oil with large waves can be dispersed first. However, it is not limited to this, and more number of toothed plates 603 can also be set as needed, for example, three, four, five or more.

Figure 6 In the figure, the second vertical plate 501 and the third vertical plate 502 have different heights in the horizontal direction, and the two are connected by a connecting bend 503. The vertical plates arranged at different positions can break up the oil at different positions, thereby reducing the noise at the center. The second vertical plate 501, the third vertical plate 502 and the connecting bend 503 can be an integrally formed structure.

[0044] Preferably, if Figures 1 to 3 and Figure 6 As shown, in the embodiment, the first wave-breaking plate portion 2 includes a first bending plate 201 and a second bending plate 202, and the first bending plate 201 and the second bending plate 202 are relatively arranged on both sides of the first end of the shell 1, and the end of the second vertical plate 501 close to the first end of the shell 1 is arranged between the first bending plate 201 and the second bending plate 202. The shell 1 can be regarded as a structure that is approximately a rectangular parallelepiped, and chamfers are provided at the four corners of the rectangular parallelepiped. In order to cooperate with the inner wall of the shell 1, the first bending plate 201 and the second bending plate 202 need to be provided with bending positions to facilitate installation and breaking up of the oil. The end of the second vertical plate 501 is provided between the ends of the first bending plate 201 and the second bending plate 202 facing each other, so that the oil can be broken up continuously. In addition, the first bending plate 201 and the second bending plate 202 can be regarded as horizontal plates, and the second vertical plate 501 is a vertical plate. Therefore, the first bending plate 201, the second bending plate 202 and the second vertical plate 501 can break up the oil from both horizontal and vertical directions to achieve the function of wave protection and noise reduction.

[0045] Preferably, if Figures 1 to 3 and Figure 6 As shown, in the embodiment, the second wave-breaking plate portion 3 includes a first wave-breaking plate 301, and the third wave-breaking plate portion 4 includes a second wave-breaking plate 401.

The dispersion columns 7 can disperse the oil, and the first dispersion holes 8 are used for the passage of the dispersed oil. The dispersion columns 7 can be formed into a cylindrical structure, and the setting direction of the cylindrical structure is the same as the setting direction of the first vertical plate 602, which can effectively disperse the oil from the vertical direction.
