And control system is made of the speed-regulating control device of drive motor, power supply and motor.
The drive motor used on battery-operated motor cycle, also known as electric dynamo.Electric dynamo includes casing, stator, rotor
And controller, stator, rotor are mounted in casing.The power of usually electricity dynamo is larger, therefore is travelled in battery-operated motor cycle
During, the calorific value of electric dynamo is very big.Electric dynamo fever can influence its normal operation, therefore to ensure electric dynamo
Normal use, usually need to radiate to it when in use.Traditional radiator structure is to open up water-cooling groove in casing end face,
By the way that cooling water is added into water-cooling groove, the heat dissipation to electric dynamo is realized.
But there is also following technical problems for above-mentioned radiator structure：Electric dynamo heating position is typically determining for casing internal
Son, rotor, and water-cooling groove is opened in end face so that the water in water-cooling groove farther out, causes with electric dynamo heating position distance
Heat dissipation effect is bad.
Utility model content
The utility model is intended to provide a kind of electric dynamo water-cooling structure, is being held with solving the setting of prior art water-cooling groove
Face so that the water in water-cooling groove farther out, leads to the problem that heat dissipation effect is bad with electric dynamo heating position distance.
To achieve the above object, the utility model provides the following technical solutions, electric dynamo water-cooling structure, including machine barrel and
The both ends of the surface of end cap positioned at machine barrel both ends, machine barrel are equipped with annular groove, and end cap is equipped with the annular protrusion coordinated with annular groove；
Annular groove upper edge machine barrel is axially evenly arranged with several through-holes, and two annular grooves include several horizontal parts and recessed portion, and water
Flat portion and recessed portion are located at the both ends of through-hole, and the horizontal part of two annular grooves is staggered；Recessed portion connects adjacent through-holes
It is logical, and form undulatory cooling duct.
The technique effect of this programme technical characteristic：
Machine barrel avoids cooling water from entering in machine barrel for installing stator and rotor, end cap for sealing machine barrel, to
Stator and rotor is avoided to meet water short circuit.Annular protrusion cooperation on annular groove and end cap on machine barrel, for realizing the close of machine barrel
Envelope.
Through-hole is for realizing the circulation of coolant liquid, and adjacent through-holes for being connected to by the recessed portion in annular groove, and ripple
The cooling duct of shape is for realizing coolant flow so that when coolant flow and the heat generating components of inside machine barrel carries out hot friendship
It changes, to realize cooling.Horizontal part can stop coolant liquid, and coolant liquid is avoided to flow between horizontal part and end cap, from
And coolant liquid and rotor or stator contact are avoided, avoid short circuit or electric dynamo failure.
The technical principle of this programme is：
Coolant liquid enters through-hole, is stopped by horizontal part so that coolant liquid forms cold along through-hole and recessed portion
But channel is flowed, and during coolant flow, is carried out heat exchange with the heat generating components of inside machine barrel, is realized to electric dynamo
It is cooling.
What this programme can generate has the technical effect that：
1, the technical program is by being arranged cooling duct on the outer wall of machine barrel so that cooling duct and electric dynamo
Heat generating components distance is closer, and heat dissipation area increases, and when coolant flow, can carry out more heat exchanges, so that
Cooling effect more preferably, while making heat dissipation more balanced；
2, adjacent through-holes are connected to by the technical program by recessed portion, form undulatory cooling duct, are enabled to cold
But the dynamic path of liquid stream is elongated, so as to improve the utilization rate of coolant liquid；
3, by the way that annular groove is arranged on machine barrel, and matched annular protrusion is set on end cap, can realize ring
Shape slot closely coordinates with annular protrusion, and coolant liquid is avoided to reveal.
It is the preferred embodiment based on said program below：
Preferred embodiment one：Based on base case, the surface of the recessed portion is corrugated.When coolant liquid passes through recessed portion,
Mobile route can be increased, to increase residence time of the coolant liquid in cooling duct so that coolant liquid carries out electric dynamo
It is adequately cooling, improve cooling effect.
Preferred embodiment two：Based on base case, the both ends of the horizontal part are equipped with catch, and the annular protrusion is equipped with
With the mounting groove of catch cooperation.Catch can limit end cap so that end cap can closely coordinate with machine barrel, avoid end cap
The case where coolant liquid caused by misplacing with machine barrel is revealed occurs.Catch can stop coolant liquid simultaneously, avoid coolant liquid
Into between end cap and parallel portion, to avoid coolant liquid from revealing.
Preferred embodiment three：Based on preferred embodiment two, the thickness of the catch is 1-2mm.If the thickness of catch is too big, can lead
Cause the weight of entire electric dynamo to increase so that battery-operated motor cycle it is big from energy consumption.Therefore the thickness of catch is set to 1-
2mm had not only been avoided that the big from energy consumption of battery-operated motor cycle, but also was avoided that the too thin caused swing of catch, realized that limit effect is good.
Preferred embodiment four：Based on preferred embodiment three, the thickness of the height and protrusion of the catch is in the same size.Work as coolant liquid
When leakage, need to flow on horizontal part out of mounting hole, but the setting of the height of catch is larger so that coolant liquid is not easy from installation
It reveals in hole.
Preferred embodiment five：Based on preferred embodiment four, the lower surface of the end cap is equipped with sealing ring along the inner ring of annular protrusion.
Sealing ring can realize the sealing to machine barrel and end cap, and coolant liquid is avoided to reveal.
Preferred embodiment six：Based on preferred embodiment five, the thickness of the sealing ring is 0.5-1mm.Pass through the thickness to sealing ring
Degree is configured, and has not only been avoided that the too thin caused sealing effect of sealing ring is bad, but also can avoid the too thick caused end of sealing ring
There is gap with machine barrel outer rim in lid outer rim；So that sealing effect is more preferably.
Preferred embodiment seven：Based on preferred embodiment six, the recessed portion surface is with the distance between horizontal part surface length
3-5cm.It is avoided that when coolant liquid enters another through-hole from a through-hole by recessed portion and enters on horizontal part, to be avoided that
Coolant liquid is revealed.
Preferred embodiment eight：Based on preferred embodiment seven, the through-hole is arc-shaped.It can be so that distance one of the through-hole away from machine tube inner wall
It causes so that it is cooling uniform, avoid electric dynamo hot-spot.
Preferred embodiment nine：Based on preferred embodiment eight, 12 through-holes are equipped in the annular groove.Through-hole is set as 12
It is a, it can either ensure that machine barrel shell keeps enough wall thickness to support stator and rotor, and can ensure that cooling effect is good.
