[0001] The utility model relates to the technical field of vehicles, in particular to a urea storage and supply device and a vehicle. Background Art

[0002] In recent years, as the requirements for automobile emissions have become increasingly stringent, more and more cars have been purifying their exhaust emissions, and the use of urea is one of the ways. Therefore, it is necessary to add corresponding space and brackets on the commercial vehicle frame to install the urea tank, which increases the difficulty of assembly design.

[0003] In the related art, many ways are used to save design space, such as designing the urea tank into an oval shape, which increases the volume while saving layout space. However, since the manufacturing process of the high-pressure resistant oval structure is relatively complicated, the cost is relatively high. In order to enhance the pressure resistance of the tank body, a partition needs to be set inside the tank, and the structure is relatively complicated. Moreover, no matter how the design is made, it is necessary to separately design complex hoops and brackets to fix the urea tank on the vehicle, which not only leads to further increase in costs, but also still occupies a large amount of chassis space, which is not conducive to the overall design of the chassis layout space.
