To fixture block is disposed with, the middle part of the semi-circular body is radially projecting to be disposed with raised fixture block, the raised fixture block
The medial extremity of end and two pieces of fixture blocks is snapped onto in annular slot, and the semi-circular body, fixture block and raised fixture block are one
Forming structure.
Preferably, the fixture block is rectangular, the end of the semi-circular body is connected with a middle side part of fixture block.
Further, the medial extremity of the fixture block is disposed with the protrusion being made of inner concave arc surface and inclined-plane, described
Inner concave arc surface is close to raised fixture block arrangement and is embedded into annular slot.
Further, the end of the raised fixture block is also disposed with inner concave arc surface and is embedded into annular slot.
Further, the outer ledge of the semi-circular body is centrally arranged arc notch.
Beneficial effect：A kind of balance block structure of automotive electronics cooling water pump motor is the utility model is related to, using balance
Block carrys out the balance of regulation motor rotor, as soon as that is, by adjusting the angle of group balance weight, that is, loss of weight is not required also without weightening
It can achieve the purpose that regulation motor rotor balancing, balance weight has the shape of special designing, and this shape is conducive to pass through
Adjustment angle achievees the purpose that adjustment balance, and is conducive to stir water body, while this shape also helps in high-speed cruising
Reduce resistance, balance weight can also stir the water body of electronic water pump bottom, prevent impurity from assembling in coolant.

Embodiment
With reference to specific embodiment, the utility model is expanded on further.It is to be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
Please the appended claims limited range.
As shown in Figs 1-4, the embodiment of the utility model is related to a kind of balance weight of automotive electronics cooling water pump motor
Structure, including rotor 2 and armature spindle 1, the both ends of the armature spindle 1 are disposed with annular slot 4, the annular slot
Insertion is provided with balance weight 3 at 4, and the balance weight 3 includes semi-circular body 33, and the both ends of the semi-circular body 33 are along footpath
To fixture block 32 is disposed with, the middle part of the semi-circular body 33 is radially projecting to be disposed with raised fixture block 34, the protrusion
The medial extremity of the end of fixture block 34 and two pieces of fixture blocks 32 is snapped onto in annular slot 4, the semi-circular body 33, fixture block 32
It is an integral molding structure with raised fixture block 34.
As the principle of the design of present patent application, the face on the basis of horizontal plane where rotor barycenter, by rotor point
For upper and lower two parts.Annular slot 4 is set apart from datum level place as far on armature spindle and places balance weight 3, rotor two
The annular slot 4 that the balance weight 3 at end disposes needs relative datum face symmetrical, 3 inner circle of balance weight and the annular slot 4 on armature spindle 1
Transition coordinates, and 3 inner circle of balance weight and the machining accuracy of annular slot 4 need to be met the requirements.
For preferably adjustment, the overall semicircular in shape of balance weight 3, easy to two balance weights 3 around 4 turns of annular slot
