In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] This embodiment provides a urea tank for use in a vehicle, wherein the vehicle includes a vehicle body, and the urea tank is disposed in the vehicle body. The existing urea tank has a problem of high noise caused by internal water flow, which seriously affects the quietness of the vehicle.

[0036] To this end, the structure of the urea tank is improved in this embodiment. Specifically, Figure 1 As shown, the urea tank includes a tank body 1, which is used to contain fluid (such as urea solution). The tank body 1 includes an upper tank body 11 and a lower tank body 12 that are interlocked, and the upper tank body 11 and the lower tank body 12 can be connected by multiple bolts.

[0037] Furthermore, if Figure 2 and Figure 3 As shown, the urea tank further includes a plurality of baffle assemblies 2, which are arranged inside the tank body 1. The plurality of baffle assemblies 2 divide the internal space of the tank body 1 into at least two sub-spaces. The baffle assemblies 2 include at least two spaced baffles 21, on which flow guide holes 211 are respectively arranged, and the flow guide holes 211 on adjacent baffles 21 are staggered so that the fluid forms a tortuous flow path between the sub-spaces and each baffle 21. Specifically, baffle assemblies 2 are arranged inside the upper box body 11 and the lower box body 12, and the baffle assemblies 2 in the upper box body 11 and the baffle assemblies 2 in the lower box body 12 are connected one by one to form a continuous baffle structure.

[0038] By arranging a baffle assembly 2 in the box body 1 to divide the internal space of the box body 1, and by arranging mutually staggered guide holes 211 on the partition 21, the water flow in the divided space is depressurized and the direction of the water flow is changed, thereby weakening the water flow power, achieving the purpose of reducing the water flow noise, thereby improving the quietness in the car.

[0039] like Figure 1-Figure 3As shown, the urea tank in this embodiment is irregular in shape, roughly T-shaped. A first sub-space 101 and a plurality of second sub-spaces 102 are provided in the tank body 1, and the plurality of second sub-spaces 102 are arranged around the first sub-space 101. Compared with urea tanks of regular shapes such as a cuboid and a cylinder, the water flow noise in the tank is greater. To this end, a baffle assembly 2 is provided between the first sub-space 101 and each second sub-space 102, and the space in the tank body 1 is divided into a relatively regular first sub-space 101 and a plurality of second sub-spaces 102 by the baffle assembly 2, so as to achieve a good effect of reducing noise.

[0040] In this embodiment, three second sub-spaces 102 are provided, and three baffle assemblies 2 are provided correspondingly to divide the space in the tank body 1. For other irregularly shaped urea tanks, the space in the tank body 1 can also be divided into multiple spaces of a certain shape by providing baffle assemblies 2 at appropriate positions. Of course, the baffle assemblies 2 proposed in this embodiment can also be applied to urea tanks of regular shapes such as cuboids or cylinders, and the baffle assemblies 2 can be used to divide the tank body 1 into sub-spaces of appropriate sizes.

[0041] like Figure 3 As shown, a urea pump is arranged on the lower box body 12 facing the first sub-space 101, and a plurality of protective plates 4 arranged at intervals are arranged around the urea pump in the upper box body 11 and the lower box body 12. The plurality of protective plates 4 surround the urea pump. After the upper box body 11 and the lower box body 12 are buckled together, the protective plates 4 on the upper box body 11 and the lower box body 12 are connected to each other, which plays a spoiler protection role, prevents the urea pump from forming a vortex in the entire box body 1 during operation, and is beneficial to reducing the noise in the urea tank.

[0042] The following focuses on the structure of the barrier assembly 2.

[0043] like Figure 4 and Figure 5 As shown, a plurality of guide holes 211 are provided on the partition 21, and the plurality of guide holes 211 on adjacent partitions 21 are staggered. In this embodiment, two partitions 21 are provided, and the fluid in one sub-space flows into between the two partitions 21 through the guide holes 211 on one partition 21, and then enters another sub-space through the guide holes 211 on the other partition 21 after changing the flow direction. In other embodiments, the baffle assembly 2 may also include three or more baffles 21, and the fluid will make multiple turns when passing through the baffle assembly 2, which can achieve better pressure relief and noise reduction effects.

[0044] Alternatively, if Figure 4As shown, the baffle assembly 2 further includes a connecting plate 22, which connects at least two baffles 21, and the connecting plate 22 and two adjacent baffles 21 form a pressure relief space 20. By providing the connecting plate 22 to connect at least two baffles 21 to form an integrated structure, it is more convenient to install in the box body 1.

[0045] Optionally, the plurality of guide holes 211 on each partition 21 are arranged in a matrix, such as Figure 5 As shown, two rows and nine columns of guide holes 211 are provided on the partition 21. It can be understood that the number of the guide holes 211 can be reasonably set according to the size of the box body 1, and no limitation is made here.

[0046] like Figure 5 As shown, the solid-line holes are the guide holes 211 on the front baffle 21, and the dotted-line holes are the guide holes 211 on the back baffle 21 that is blocked, and the guide holes 211 on adjacent baffles 21 are completely staggered, that is, the projection of the guide holes 211 on one baffle 21 on the adjacent baffle 21 falls on the entity of the baffle 21, and does not overlap with the guide holes 211 on the adjacent baffle 21, so that the guide holes 211 on adjacent baffles 21 are staggered by a larger size, thereby changing the water flow direction to a greater extent.

[0047] In this embodiment, Figure 5 As shown, the guide hole 211 is set as a circular hole. Of course, the guide hole 211 can also be set as an elliptical hole, a square hole or a shutter-shaped opening, as long as it can allow fluid to pass through, and the specific shape of the guide hole 211 is not limited here.

[0048] In order to improve the flexibility of the application of the baffle assembly 2, the baffle assembly 2 can be detachably connected to the box body 1. Specifically, the baffle assembly 2 can be connected and fixed in the box body 1 by snap fastening, screw fastening, glue fastening, ultrasonic welding fastening, etc.

[0049] In this embodiment, the baffle assembly 2 is snap-fitted into the box body 1. Specifically, Figure 6 As shown, a plug-in assembly 13 is provided on the inner wall of the box body 1. The plug-in assembly 13 includes two enclosure plates 131 and abutment plates 132. The two enclosure plates 131 surround an insertion slot 130. The end of the barrier assembly 2 is inserted into the insertion slot 130. The barrier assembly 2 also includes an elastic buckle 23. The abutment plates 132 are provided between the two enclosure plates 131. When the barrier assembly 2 is inserted into the insertion slot 130, the abutment plates 132 abut against the elastic buckle 23. A plug-in assembly 13 is provided at each end of the barrier assembly 2. During installation, the two ends of the barrier assembly 2 are respectively inserted into the insertion slot 130. The barrier assembly 2 is limited by the two enclosure plates 131. After the barrier assembly 2 is fully inserted into the insertion slot 130, the elastic buckle 23 will abut against the abutment plates 132 to prevent the barrier assembly 2 from falling out of the insertion slot 130.

[0050] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
