Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a brainless water pump. Background Art

[0002] Based on the relatively complex control part of the whole vehicle, the prior art is applicable to the integrated module one-piece type and the whole vehicle U control. There is no need for single water pump control. The water pump is controlled by the whole vehicle controller, which simplifies the water pump structure and reduces the overall weight of the product by 30%.

[0003] However, when the coolant of the water pump is insufficient, the temperature rise of the water pump rises rapidly, and there is a risk of decomposition of the stator shaft plastic coating, and the product is not easy to be injection molded. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a brainless water pump.

[0005] A brainless water pump includes a pump housing, a wear-resistant gasket, an impeller rotor assembly, and a motor assembly. It also includes a stator shaft, a motor plastic coating welding rib arranged on the motor assembly, and a gasket arranged at the intersection of the stator shaft and the motor assembly. The connection control with the whole vehicle is realized through a motor plug designed by the motor assembly.

[0006] As a further improvement of the utility model, the gasket is arranged at the bottom of the motor assembly.

[0007] As a further improvement of the utility model, the gasket is plastically coated and matched with the motor assembly.

[0008] As a further improvement of the utility model, the gasket is made of stainless steel material.

[0009] As a further improvement of the utility model, the motor plastic coating welding rib is injection molded.

[0010] As a further improvement of the utility model, the motor assembly includes a stator, and a positioning groove for positioning the mold position is arranged on the outer side of the stator.

[0011] The beneficial effects of the utility model are as follows:

[0012] The utility model controls the water pump by using the whole vehicle controller, making the product lightweight and simple, reducing the overall weight by 30%. The connection control with the whole vehicle is realized through the motor plug, and the gasket plastic coating is added to prevent flash, with wear resistance and not easy to deform.

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model is further described below.

[0021] As Figures 1 to 5 shown, a brainless water pump includes a pump housing 1, a wear - resistant gasket 2, an impeller rotor assembly 3, a motor assembly 4, and also includes a stator shaft, a motor plastic - coated welding rib 5 arranged on the motor assembly 4, and a gasket 6 arranged at the intersection of the stator shaft and the motor assembly 4. The connection control with the whole vehicle is realized through a motor plug designed on the motor assembly 4.

[0022] The said gasket 6 is arranged at the bottom of the motor assembly 4.

[0023] The present utility model controls the water pump through a vehicle controller, making the product lightweight and simple. The overall weight is reduced by 30%. The connection control with the whole vehicle is realized through a motor plug, and the gasket is plastic - coated to prevent flying edges, being wear - resistant and not easy to deform.

[0024] As Figure 4 and Figure 5 shown, the said gasket 6 is plastically - coated and matched with the motor assembly 4, and the plastic - coated pps material can prevent flying edges.

[0025] The said gasket 6 is made of stainless steel material. When the hole of the impeller rotor assembly 3 is dry - ground with the motor assembly 4, it is not easy to deform and has a high wear - resistance. When the pps reaches the melting point of 250 degrees, it begins to decompose and plasticize.

[0026] The plastic-coated welding rib 5 of the motor is injection-molded. In the original structural design, the rib was inside the fluid domain. The R-angle was too small to be easily molded, resulting in pinholes and causing a leakage risk for the water pump. If the R-angle was too large, it would interfere with the impeller rotor assembly 3. In this structure, the rib is designed to be guided from the mixed cavity of the medium chamber to the outside, solving the problem of poor injection molding in the wet cavity of the medium chamber, which may cause the water pump to fail. At the same time, the strength of the rib can also meet the requirements.

[0027] As Figure 1 shown, the motor assembly 4 includes a stator, and a positioning groove 7 for positioning the mold position is provided on the outer side of the stator. The advantage of this design is to facilitate the product positioning before the injection molding process of the mold.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
