Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.

An automotive expansion kettle (water tank) is a component of a cooling system and is a container for filling and compensating liquid for the cooling system. When the automobile engine is running, the cooling liquid can circulate in the cooling water channel continuously, and the cooling liquid can flow through the expansion kettle in the middle. If the pressure is too high or the cooling liquid is excessive, the redundant gas and the cooling liquid flow out from a bypass water channel of the expansion kettle, so that the adverse effects of the too high pressure and the sudden tube are avoided.

The expansion kettle is an important part of a whole vehicle thermal management system, and particularly in a pure electric vehicle, a plurality of waterway cycles are needed, and two or even three expansion kettles are possibly arranged on a single vehicle. At present, most of the mounting modes of the expansion kettles adopt a bolt connection mode, a plurality of bolts are adopted to be mounted on a mounting bracket of the expansion kettles, and the time spent in the whole vehicle assembly is long; by adopting a plurality of bolts, the overall weight of the vehicle is large, the disassembly, assembly and maintenance are inconvenient, and there is room for improvement.

The side of the clamping side ear 220 facing the first comb structure 22 includes a first inclined surface 221 and a second inclined surface 222, and the first inclined surface 221 and the second inclined surface 222 form a protrusion facing the first comb structure 22. Through the clamping side ear 220 comprising the first inclined surface 221 and the second inclined surface 222, after the first mounting hole 31 of the first mounting plate 32 is sleeved into the comb tooth body of the first comb tooth structure 22 from bottom to top and moves upwards continuously, the first mounting plate 32 can be enabled to move upwards along the first inclined surface 221 and be clamped between the upper surface of the first elastic member 21 and the comb tooth base of the first comb tooth structure 22 conveniently by pushing the first elastic member 21 towards one side of the expansion kettle 10 after contacting the first inclined surface 221 of the clamping side ear 220. Thus, the expansion kettle 10 is conveniently mounted to the mounting bracket.

As shown in fig. 3-5, in some embodiments of the present disclosure, the resilient body 210 of the first resilient member 21 includes a back side 401 facing the sidewall of the expansion kettle 10, and a first end face 402 and a second end face 403 connecting the back side 401.
