Description

Technical Field

[0001] This utility model relates to automotive parts, and in particular to an automotive electronic water pump impeller assembly. Background Technology

[0002] Most automotive electronic water pump impeller assemblies on the market use neodymium iron boron magnetic ring structures, which are prone to high temperature problems and cracks after rotation. Summary of the Invention

[0003] To solve the aforementioned technical problem of cracks, this utility model provides an automotive electronic water pump impeller assembly.

[0004] The technical solution of this utility model is as follows:

[0005] An automotive electronic water pump impeller assembly includes an upper impeller body, which is connected to a lower impeller body via a graphite bearing. The upper impeller body has a graphite bearing in the middle, and wheel blades are arranged from the inside to the outside of the graphite bearing. The wheel blades are obliquely arranged and have an arc shape. The lower impeller body is wrapped with ferrite.

[0006] The number of wheel pieces is five, and they are evenly distributed.

[0007] The impeller is covered with a 0.5 MPPS plastic shell.

[0008] The lower part of the impeller has a graphite bearing in the middle, and ferrite is injection molded through the outer plastic part of the impeller. The bottom of the lower part of the impeller is hollow.

[0009] There is a gap between the upper impeller body and the lower impeller body.

[0010] The diameter of the upper impeller body is larger than the diameter of the lower impeller body.

[0011] Using the technical solution of this utility model, the middle part is a graphite bearing, and the outer part of the graphite bearing is the upper body of the lower wheel and the lower body of the impeller. Through injection molding, the strength is stronger and the pressure resistance is better. The wheel pieces are arranged from the inside to the outside and the wheel pieces are set at an angle, which makes it easy to release pressure, reduce impact force, and is not prone to cracks. The injection-molded ferrite and the outer plastic part of the impeller are used to avoid a series of problems caused by the magnetic ring coming into contact with the liquid.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example

[0017] like Figure 1 , 2 As shown in Figure 3, an automotive electronic water pump impeller assembly includes an upper impeller body 2, which is connected to a lower impeller body via a graphite bearing 1. The upper impeller body 2 has a graphite bearing 1 in the middle, and the graphite bearing 1 has wheel plates from the inside to the outside. The wheel plates are arc-shaped, and the lower impeller body is wrapped with ferrite 3.

[0018] The number of wheel pieces is five, and they are evenly distributed.

[0019] The impeller outer plastic part 4 is a 0.5 MPPS shell.

[0020] The lower part of the impeller has a graphite bearing 1 in the middle, and ferrite 3 is injection molded through the outer plastic part 4 of the impeller. The bottom of the lower part of the impeller is hollow.

[0021] There is a gap between the upper impeller body 2 and the lower impeller body.

[0022] The diameter of the upper impeller body 2 is larger than the diameter of the lower impeller body.

[0023] In use, the graphite bearing 1, the upper impeller body 2, and the lower impeller body are first injection molded, and the injection-molded ferrite 3 is simultaneously injection molded. Finally, the outer plastic part 4 of the impeller is injection molded to form the impeller assembly. The injection-molded layer is thick and reinforced. Combined with the characteristics of the impeller blade, it is easy to resist pressure and is not prone to cracking. In addition, the ferrite 3 injection molding also makes it less susceptible to high temperatures.

[0024] It should be understood that the above description is only a preferred embodiment of the present utility model and is not sufficient to limit the technical solution of the present utility model. For those skilled in the art, within the spirit and principles of the present utility model, additions, subtractions, substitutions, transformations or improvements can be made based on the above description, and all such additions, subtractions, substitutions or improvements should fall within the protection scope of the appended claims of the present invention.
