Problems solved by technology

The transmission methods are both the liquid cavity and the motor rotor cavity, which are in the same cavity, so that both methods affect the smooth rotation of the motor rotor, consume the moment of inertia of the motor and the output power of the motor, and at the same time, the magnetic drive relationship of the motor cannot be obtained. Reasonable size gap affects the efficiency of the motor, but the existing electronic water pumps for vehicles have not been able to realize the universal management of the motor structure, which has caused trouble for mass production

Embodiment Construction

[0017] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0018] Such as figure 1 Shown, a kind of vehicle electronic water pump, it comprises:

[0019] A casing, the casing is provided with a partition 1, and the partition 1 divides the cavity in the casing into an upper cavity and a lower cavity that are independent of each other;

[0020] a motor assembly, the motor assembly is arranged in the lower cavity;

[0021] The pump body assembly is arranged in the upper cavity.

[0022] Such as figure 1 As shown, the housing includes an upper housing 21 and a lower housing 22 that are engaged with each other.

[0023] Such as figure 1 As shown, the motor assembly includes a first permanent magnet structure 4, a rotor 5 and a stator 6, a shaft passing through the upper cavity and the lower cavity is arran...

Abstract

The invention discloses a vehicle electronic water pump comprising a shell, a motor assembly and a pump body assembly. A partition plate is arranged in the shell, a cavity in the shell is divided by the partition plate into an upper cavity and a lower cavity which are mutually independent, the motor assembly is arranged in the lower cavity, and the pump body assembly is arranged in the upper cavity. According to the vehicle electronic water pump, the motor assembly and the pump body assembly are located in the two completely-independent cavities, mutual interference is avoided, thus a rotor ofthe motor assembly rotates stably, and the efficiency of the motor assembly is also improved.

Description

technical field [0001] The invention relates to an electronic water pump for vehicles. Background technique [0002] At present, most of the existing vehicle water pumps are electronic water pumps in which the permanent magnet non-contact motor drives the rotor of the motor to rotate through the magnetic field and drives the blades of the pump body to work. Existing electronic water pumps for vehicles are generally divided into two types: 1. Outer rotor type permanent magnet non-contact motor, electronically controlled. 2. Inner rotor type permanent magnet non-contact motor, programmed control. The transmission methods are both the liquid cavity and the motor rotor cavity, which are in the same cavity, so that both methods affect the smooth rotation of the motor rotor, consume the moment of inertia of the motor and the output power of the motor, and at the same time, the magnetic drive relationship of the motor cannot be obtained. The reasonable size gap affects the effici...
