One uncontrollable space of rotor can be formed on bottom, and this space has the aggregation of coolant.
Engine vibration is in itself lacked in new energy car, on vehicle and noise, the NVH performance requirements of parts is also more next
Higher, electronic water pump especially can not be ignored as a part to work always, noise effect, caused by rotor imbalance
Noise effect accounts for very big ratio in the vibration of electronic water pump assembly and noise.
Due to inevitably containing partial impurities in automobile cooling, the larger impurity of proportion can be with the time in electronic water
The rotor bottom aggregation of pump, if things go on like this, the impurity of aggregation not only can produce noise with friction rotor, and more part can be caused to grind
Damage, causes part failure, so needing a kind of special structure to exist to improve rotor rotation imbalance and coolant impurity
The situation of rotor bottom aggregation.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of balance block structure of automotive electronics cooling water pump motor, adopt
With balance block structure, it is not necessary to which traditional plus-minus Material Balance mode, process operations are simpler, counterbalance effect is more preferable.
The technical solution adopted for the present invention to solve the technical problems is：A kind of automotive electronics cooling water pump motor is provided
Balance block structure, including rotor and armature spindle, the both ends of described armature spindle are disposed with annular slot, described annular snap
Insertion is provided with balance weight at groove, and described balance weight includes semi-circular body, and the both ends of the semi-circular body are along radial direction cloth
Fixture block is equipped with, the middle part of described semi-circular body is radially projecting to be disposed with raised fixture block, the end of described raised fixture block
Snapped onto with the medial extremity of two pieces of fixture blocks in annular slot, described semi-circular body, fixture block and raised fixture block are integrated into
Type structure.
Preferably, described fixture block is rectangular, the end of described semi-circular body is connected with a middle side part of fixture block.
Further, the medial extremity of described fixture block is disposed with the jut being made up of inner concave arc surface and inclined-plane, described
Inner concave arc surface is arranged and is embedded into annular slot close to raised fixture block.
Further, the end of described raised fixture block is also disposed with inner concave arc surface and is embedded into annular slot.
Further, the outer ledge of described semi-circular body is centrally arranged arc notch.
Beneficial effect：The present invention relates to a kind of balance block structure of automotive electronics cooling water pump motor, using balance weight come
The balance of regulation motor rotor, i.e., by adjusting the angle of one group of balance weight, that is, loss of weight is not needed also without weightening can
Reach the purpose of regulation motor rotor balancing, balance weight has the shape of particular design, and this shape is advantageous to pass through adjustment
Angle reaches the purpose of adjustment balance, is advantageous to stir water body again, while this shape also helps reduction in high-speed cruising
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 present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As Figure 1-4, embodiments of the present invention are related to a kind of balance block structure of automotive electronics cooling water pump motor,
Including rotor 2 and armature spindle 1, the both ends of described armature spindle 1 are disposed with annular slot 4, embedding at described annular slot 4
Enter to be provided with balance weight 3, described balance weight 3 includes semi-circular body 33, and the both ends of the semi-circular body 33 are along radial direction cloth
Fixture block 32 is equipped with, the middle part of described semi-circular body 33 is radially projecting to be disposed with raised fixture block 34, described raised fixture block
The medial extremity of 34 end and two pieces of fixture blocks 32 is snapped onto in annular slot 4, described semi-circular body 33, fixture block 32 and convex
Fixture block 34 is played to be formed in one structure.
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 reference plane 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, the inner circle of balance weight 3 and the annular slot 4 on armature spindle 1
The machining accuracy of interference fits, the inner circle of balance weight 3 and annular slot 4 need to meet to require.
For preferably adjustment, 3 overall semicircular in shape of balance weight, it is easy to two balance weights 3 around 4 turns of annular slot
Move and carry out angular adjustment；Balance weight 3 is with annular slot 4 by three point contact, and this 3 points on the circumference of same circle.
The global shape particular design of the design balance weight 3, that is, ensure to play the work of stirring impurity in coolant transfer kinetic energy
With due to preponderance overall load will not being caused to increase again, balance weight center section hollow out loss of weight, configuration design is into middle circle
Arc, both ends are rectangular-shaped, circular sliding slopes between circular arc and rectangle, it is ensured that when rotating speed is higher, resistance will not be very big, reduces work(
Consumption.
By the rotation of lower section balance weight, flowing of the coolant in separation sleeve bottom can be effectively facilitated.This mode
The possibility of accumulation of impurities can be reduced.
Described fixture block 32 is rectangular, and the end of described semi-circular body 33 is connected with a middle side part of fixture block 32, this
The structure of sample can ensure that resistance will not be very big when rotating speed is higher, reduces power consumption.
The medial extremity of described fixture block 32 is disposed with the jut being made up of inner concave arc surface 36 and inclined-plane 31, described indent
Cambered surface 36 is arranged and is embedded into annular slot 4 close to raised fixture block 34, by setting inner concave arc surface 36 to ensure and annular
The madial wall fitting of neck 4, improve the stability of balance weight 3.
The end of described raised fixture block 34 is also disposed with inner concave arc surface 36 and is embedded into annular slot 4.
The outer ledge of described semi-circular body 33 is centrally arranged arc notch 35, facilitate balance weight 3 dismantle when
Semi-circular body 33 is waited to deform in the position of arc notch 35.
The present invention uses balance block structure, it is not necessary to which traditional plus-minus Material Balance mode, process operations are simpler, balance
Effect is more preferable.
