[0022] The structure, features and advantages of the pump housing, pump device and vehicle according to the present application will be described below by way of example, however, it should be understood that all the descriptions should not be used to limit the present application. For the purpose of simplifying the drawings, the same or similar parts and features can be marked only at one or several places in the same drawing.

[0023] Firstly, in Figure 1 the general configuration of the pump housing, base and sealing ring in an embodiment of the pump device according to the present application is shown. As Figure 1 shown, the pump housing 10, base 20 and sealing ring 30 in the pump device 100 are shown in the drawing, it should be understood that the pump device 100 can include other parts not shown in the drawing, such as impeller, etc.

[0024] For the pump housing 10 and base 20, they can be configured to have any suitable structural shape according to the application requirements, for example, in Figure 1 exemplarily shown in Figure 4 the connecting portion 14 on the pump housing 10 can be used to be assembled with the base 20, for example, the connecting portion 14 and the base 20 can be fixed together by welding connection or the like.

[0025] The sealing ring 30 can be made of suitable material and configured to have suitable configuration and size according to the requirements, for example, O-ring made of nitrile rubber or polytetrafluoroethylene or the like can be used, the sealing ring 30 can be fitted on the base 20, after the assembly of the pump housing 10 and the base 20 is completed, the sealing ring 30 is abutted between the inner wall 11 of the pump housing 10 and the base 20 to play a sealing role, in Figure 4 the above assembly arrangement of the sealing ring 30 has been exemplarily shown in

[0026] With reference to Figure 2 and Figure 3 , according to the present disclosure, a plurality of protrusions 15 can be provided on the inner wall 11 of the pump housing 10, the protrusions 15 are arranged along the circumference of the inner wall 11, the specific configuration number thereof can be designed according to the actual requirements, for example, 2-50 can be optionally provided, such as 3, 4, 8 or 10, etc., inFigure 2 The illustration shows a demonstration scenario with six protrusions simultaneously. The protrusions 15 can be evenly arranged along the circumference of the inner wall 11 of the pump housing 10; in one or more embodiments, these protrusions 15 can also be arranged non-uniformly on the inner wall 11 to fully adapt to different application needs.

[0027] In the prior art described above, the sealing ring is compressed during the installation of the pump housing and base to achieve a sealing effect. This compression creates a contact force between the sealing ring and the pump housing, causing the pump housing to deviate from its intended installation position. This leads to problems and risks in subsequent assembly work, potentially requiring multiple repetitions to correctly position the pump housing, thus affecting installation efficiency and product quality. In contrast, the present invention, by providing a protruding structure on the inner wall of the pump housing, can reliably and stably fix the pump housing in the correct installation position, forming a strong contact between the pump housing and the base. Specifically, it eliminates the radial gap commonly present between the pump housing and base in existing products, effectively solving or mitigating the aforementioned adverse effects of the sealing ring on the pump housing. This not only allows for a more accurate installation position of the pump housing and makes installation more convenient and efficient, but also ensures the smooth progress of subsequent assembly work.

[0028] In practical applications, pump housings with the aforementioned protrusions can be manufactured using any one or more feasible processes, such as casting or machining. Figure 2 and Figure 3 As shown, the protrusion 15 can be configured to have an extension 16, the extension 16 having a length extending in a direction parallel to the axis L of the pump housing 10, and the extension 16 being spaced apart from the corresponding contact portion of the sealing ring 30 on the inner wall 11 to avoid interference between them. For example, as an example, in Figure 4 The diagram shows that the protrusion 15 can be disposed on the first annular section 12 of the pump housing 10, which has a relatively larger inner diameter compared to the adjacent second annular section 13; after the pump housing 10, base 20 and sealing ring 30 are assembled, the sealing ring 30 will abut against the second annular section 13, so that no interference is formed between the sealing ring 30 and the protrusion 15.

[0029] Generally, all extensions 16 of the protrusions 15 are made to be perfectly parallel to the axis L. In one or more embodiments, it is also permissible for one or more extensions 16 of the protrusions 15 to maintain an angle of inclination with the axis L, provided that after the pump housing 10 and the base 20 are installed and connected, the gap between them can be eliminated by the abutting between the extensions 16 of the protrusions 15 and the base 20. Figure 4The above mounting arrangement of the protrusion 15 is schematically shown.

[0030] In the pump housing 10, the extension 16 of the protrusion 15 can be configured in any desired structure, shape, size, etc. according to the application requirements. By way of illustration, the extension 16 can be configured to have any suitable cross section, such as an arc shape or a polygonal shape, for example a semicircular shape, a semi-elliptical shape, a parabolic shape, a triangular shape, a rectangular shape, etc., and the extension 16 can form a line contact between the outer profile of the extension 16 and the base 20 when the base 20 is in abutting contact with the extension 16. By way of further illustration, the thickness of the extension 16 can be optionally set at 0.6-1.2mm, for example at 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, etc.

[0031] By configuring the extension 16 of the protrusion 15 in a suitable size and shape, etc. as required, the actual requirements in different application environments can be met, in particular, on one hand, the gap between the pump housing and the base in the existing pump device during installation can be eliminated, and on the other hand, it is also beneficial to avoid excessive contact force between the pump housing and the base, so as to not only effectively reduce the assembly difficulty of the pump housing, but also better meet the assembly requirements.

[0032] Further, the application also provides a vehicle, and one or more pump devices according to the application can be configured on the vehicle according to actual requirements, so as to bring the above-mentioned obvious technical effects superior to the prior art. It should be noted that the pump device according to the application can include but is not limited to an electric pump, etc., and the vehicle according to the application has a wide range of types, such as a pure electric vehicle, a hybrid vehicle, a fuel vehicle, etc.

[0033] The pump housing, the pump device and the vehicle according to the application are only illustrated in detail by way of example, and these examples are only used to illustrate the principles and implementation modes of the application, and do not limit the application, and various modifications and improvements can be made by those skilled in the art without departing from the scope of the application. Therefore, all equivalent technical solutions shall belong to the scope of the application and be limited by the claims of the application.
