Description

Technical Field

[0001] The present application relates to the technical field of cooling liquid jugs, and in particular to a cavity structure of a cooling liquid jug. Background Art

[0002] Coolant pots are usually used in vehicle cooling systems, including fuel vehicle engine cooling, new energy vehicle motor and electronic control cooling, air conditioning cooling, and battery cooling systems. The functions of the coolant pot are water holding and pressure maintaining.

[0003] Most of the current coolant pots are of a cubic structure, with fixing ears fixed around the cube-shaped coolant pot, and a mounting space corresponding to the shape of the coolant pot is reserved in the car body. When the coolant pot needs to be installed, the coolant pot is first placed in the mounting space, and then the fixing ears are threadedly connected to the reserved mounting holes in the car body by bolts, and the coolant pot is fixedly installed in the mounting space.

[0004] However, with the development of the automobile industry, the functions of automobiles are becoming more and more complete, and the number of electronic components matching them is increasing. Therefore, when the body space remains unchanged, some electronic components or body structures will occupy the installation space of the coolant pot, making it impossible to install the coolant pot with the original cube structure in the irregular installation space. Utility Model Content

[0005] In order to improve the convenience of installing a coolant pot, the present application provides a cavity structure of a coolant pot.

[0006] The present application provides a cavity structure of a coolant pot, which adopts the following technical solution:

[0008] By adopting the above technical solution, the upper pot body and the lower pot body are combined to form a coolant pot, wherein the lower pot body includes a flat pot part, a connecting part and a wide pot part, and the three form a stepped shape so as to be suitable for the installation space of the coolant pot in an irregular vehicle body, thereby facilitating the installation of the coolant pot.

[0009] Optionally, the connecting portion includes a first sub-portion and a second sub-portion, the first sub-portion is fixedly connected to the top surface of the second sub-portion, one side of the first sub-portion is fixedly connected to the flat pot portion, and the other side of the first sub-portion and the same side of the second sub-portion are both fixedly connected to the wide pot portion.

[0017] Optionally, the interior of the flat pot portion is transversely divided into five flat pot cavities, the five flat pot cavities are connected in sequence, and outer walls of two of the flat pot cavities are provided with overlapping inner concave surfaces.

[0018] By adopting the above technical solution, compared with the connecting part, there is one more cavity, which is beneficial to increase the volume of the flat pot part.

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] Example:

[0031] See also Figure 1 , a cavity structure of a coolant pot, comprising an upper pot body 1 and a lower pot body 2. The upper pot body 1 and the lower pot body 2 are combined to form a coolant pot, the upper pot body 1 is fixed to the top surface of the lower pot body 2, and the upper pot body 1 and the lower pot body 2 are fixedly connected. Among them, the lower pot body 2 comprises a flat pot part 3, a connecting part 4 and a wide pot part 5, the height of the flat pot part 3 is half of the height of the wide pot part 5, the connecting part 4 is located between the flat pot part 3 and the wide pot part 5, and the flat pot part 3, the connecting part 4 and the wide pot part 5 are fixedly connected in sequence.

[0032] The flat pot portion 3, the connecting portion 4 and the wide pot portion 5 form a step shape, and adapt to the irregular installation space of the vehicle body by changing their own shapes.

[0033] For details, see Figure 1The connecting portion 4 includes a first sub-portion 6 and a second sub-portion 7. The first sub-portion 6 is fixedly connected to the top surface of the second sub-portion 7. The height of the first sub-portion 6 is the same as that of the flat pot portion 3. The first sub-portion 6 serves as a connecting medium between the flat pot portion 3 and the flat pot portion of the wide pot portion 5. The first sub-portion 6 is fixedly connected to the flat pot portion 3 and the wide pot portion 5 respectively. The second sub-portion 7 serves as a connecting medium between the flat pot portion 3 and the wide pot portion of the wide pot portion 5. The height of the combination of the first sub-portion 6 and the second sub-portion 7 is the same as that of the wide pot portion 5, and the second sub-portion 7 is fixedly connected to the wide pot portion 5.

[0034] Under the connection medium of the first sub-section 6 and the second sub-section 7, the flat pot section 3 and the wide pot section 5 are combined to form a continuous step, thereby maintaining the overall structure of the coolant pot.

[0035] It is worth mentioning that see Figure 1 and Figure 2 A first cambered surface 8 is fixed to the outer wall of the second sub-portion 7. Under the action of the first cambered surface 8, the shape of the connecting portion 4 is changed, so that the coolant pot is more suitable for the installation space of the vehicle body.

[0036] In addition, the inner wall of the second sub-section 7 is laterally divided into four connecting cavities 9, the four connecting cavities 9 are connected in sequence, and the outer wall of the connecting cavity 9 close to the side is concave.

[0037] The cavity of the coolant tank has three main functions. The first is to separate the liquid in the tank and "hold" the liquid to avoid excessive displacement of the liquid level under extreme working conditions. The second is NVH. Reasonable compartments can effectively reduce the impact sound of water flow. The third is to improve the strength of the coolant tank shell. When the water tank is used as DV, there are requirements for bursting pressure and static pressure. At the same time, according to the shape of the actual vehicle body installation space, the outer wall of the side connection cavity 9 is set to be concave.

[0038] For details, see Figure 1 and Figure 3 The flat pot portion 3 is laterally divided into five flat pot cavities 10, which are closely arranged in a straight line, connected in sequence, and arranged in two rows. Compared with the four connecting cavities 9 of the connecting portion 4, the five flat pot cavities 10 are arranged to increase the volume of the flat pot portion 3 in the horizontal direction. The outer walls of two adjacent flat pot cavities 10 are provided with overlapping inner concave surfaces 11. The overlapping inner concave surfaces 11 are mainly installed and made room according to the actual internal structure of the vehicle body, so as to improve the convenience of installing the coolant pot.

[0039] Moreover, a second cambered surface 12 is fixed to the outer wall of the flat pot portion 3 , and the first cambered surface 8 is connected to the second cambered surface 12 , thereby ensuring the structural continuity of the flat pot portion 3 and the connecting portion 4 being fixedly connected.

[0040] For details, see Figure 1 and Figure 3The wide pot portion 5 is internally divided into four wide pot cavities 13, which are connected in sequence, and the wide pot cavities 13 are arranged in two rows. The two wide pot cavities 13 at both ends are respectively fixedly connected with circulating liquid pipes 14.

[0041] The number of the wide pot cavities 13 corresponds to the number of the connecting cavities 9, so as to maintain the continuity of the overall structure of the coolant pot. The circulating liquid pipe 14 is used to circulate the coolant in the coolant pot to the vehicle body cooling system.

[0042] It is worth noting that see Figure 1-Figure 3 The flat pot portion 3 is away from the side of the wide pot portion 5 and the two sides of the wide pot portion 5 are all fixed with fixed points 15. Under the effect of the fixed points 15, it is convenient for the coolant pot to be fixedly installed in the vehicle body.

[0043] The working principle of the cavity structure of a coolant pot:

[0044] The upper kettle body 1 and the lower kettle body 2 are combined to form a coolant kettle, wherein the lower kettle body 2 includes a flat kettle portion 3, a connecting portion 4 and a wide kettle portion 5. At the same time, under the action of the first arc surface and the second arc surface, the three form a structurally coherent stepped shape.

[0045] In summary, changing the structural shape according to the actual irregular installation space of the vehicle body is beneficial to improving the convenience of installing the coolant pot in the vehicle body.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
