Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the application is described in further detail.Implement below
Example is not limited to scope of the present application for illustrating the application.
Fig. 1 to Fig. 4 is the structural schematic diagram for the electronic water pump for automobile that the application one embodiment provides, as shown in Figure 1, should
Electronic water pump for automobile includes at least: electric machine casing 1；The motor stator 2 and rotor 3 being installed in electric machine casing 1, motor is fixed
Son 2 is tooth slot structure；The impeller 4 being connect with the front end of rotor 3；It covers on 1 front end of electric machine casing and is provided with and accommodate impeller 4
Impeller cavity spiral case 5, there is on spiral case 5 cut water 51 (referring to Fig. 2).Tooth slot structure includes multiple tooth sockets 21 (with reference to Fig. 3).
Wherein, impeller 4 and rotor 3 are fixed in axis and bearing system 6, with the rotation of identical speed.Spiral case 5 and motor are fixed
Son 2 is static relative to electric machine casing 1.
In said structure, as can be seen from FIG. 2, when the blade of impeller 4 passes through the cut water 51 on spiral case 5, due to fluid
Effect, the blade of impeller 4 will generate a driving frequency.This frequency and wheel speed, the factors such as blade quantity are related.
As can be seen from FIG. 3, due to slot effect, the magnetic field of permanent magnet of rotor 3 is mutual with the tooth socket 21 of motor stator 2
Effect, in the torque that circumferencial direction generates.In variable speed drives, when torque frequency is consistent with the driving frequency of blade, tooth socket
The vibration and noise that 21 torques generate will be amplified.
Based on above-mentioned noise producing cause, in the present embodiment, cut water 51 is not overlapped with any tooth socket 21 on tooth slot structure.
At this point, the driving frequency of blade will not be caused altogether with motor part due to the torque frequency phase mutual excitation that slot effect generates
Vibration.
With reference to Fig. 5, the angle between any tooth socket 21 in 51 vertex of cut water and tooth slot structure is predetermined angle a；It is default
Angle a is overlapped cut water 51 not with tooth socket 21.Wherein, the angle between 51 vertex of cut water and tooth socket 21 refers to: cut water 51 pushes up
The second line that the first line 510 that point is constituted with 2 center of motor stator is constituted with 21 center of tooth socket and 2 center of motor stator
Angle between 520.
Optionally, guarantee that the tooth socket 21 of motor stator 2 and the mode that cut water 51 is not overlapped are including but not limited to following several:
The first: referring to Fig. 6, and the first contraposition mark (not shown) is provided on electric machine casing 1, is arranged on motor stator 2
There is the second contraposition to identify 61；First contraposition mark and the sensible clock synchronization of the second register guide make the tooth socket 21 and cut water of motor stator 2
51 are not overlapped.
Second: the first limiting slot is provided on electric machine casing 1, the first limiting slot limits motor stator 2 in electric machine casing 1
In installation site so that the tooth socket 21 of motor stator 2 is not overlapped with cut water 51.
The third: the fixing bolt angle between spiral case 5 and electric machine casing 1 is overlapped cut water 51 not with tooth socket 21.This
When, when using fixing bolt connection spiral case 5 and electric machine casing 1, it can control the fixing bolt angle and make cut water 51 and tooth
Slot 21 is not overlapped.
4th kind: the second limiting slot is provided on electric machine casing 1, the second limiting slot limits the company of spiral case 5 and electric machine casing 1
Position is connect, so that the tooth socket 21 of motor stator 2 is not overlapped with cut water 51.
Certainly, the tooth socket 21 of guarantee motor stator 2 can also be other modes, this implementation with the mode that cut water 51 is not overlapped
Example will not enumerate herein.
Certainly, electronic water pump for automobile can also include other assemblies, such as: rear end cap, graphite bushing, magnetic shoe, graphite pads,
Pump shaft etc., this is no longer going to repeat them for the present embodiment.
In conclusion electronic water pump for automobile provided in this embodiment, by the way that electric machine casing is arranged；It is installed in electric machine casing
Motor stator and rotor, the motor stator be tooth slot structure；The impeller being connect with the front end of rotor；Cover on motor
Housing forward end is simultaneously provided with the spiral case for accommodating the impeller cavity of impeller, has cut water on the spiral case；Wherein, cut water and tooth slot structure
On any tooth socket be not overlapped；It can solve the larger problem of existing electronic water pump for automobile noise；Due to cut water and tooth socket knot
Structure is no longer opposite, and the driving frequency of blade will not mutually be swashed with motor part due to the torque frequency that slot effect generates at this time
It encourages and causes to resonate, therefore the noise for causing resonance to generate with torque frequency phase mutual excitation due to driving frequency can be eliminated, thus
Reduce the noise of electronic water pump for automobile.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
