As shown in Fig. 2 the water pump 1 that the utility model is proposed includes pump case 2, motor casing 3, end cap 4.Wherein, motor casing 3
Pump case 2 is installed at one end, end cap 4 is installed at the other end.
The pump case 2 limits the pump chamber for accommodating water pump vane, the drive backspin of the impeller of the water pump 1 in motor shaft
Turn, to be pumped to the liquid in pump chamber.The liquid of pumping can according to the application scenario of water pump 1 different, Ke Yiwei
Water, coolant, lubricating fluid, and other various liquid.It is applied in water pump 1 in the situation of the cooling system of vehicle, water pump 1 can
With for pumping the coolant of vehicle.
Together with motor casing 3 can be bolted on pump case 2.Can on counterface between motor casing 3 and pump case 2
Sealing ring 12, such as O-ring seal are provided with, to ensure the sealing between motor casing 3 and pump case 2.
Water pump 1 has rotor chamber 5, bore of stator 6, control chamber 7.Rotor 9 is rotatably installed in rotor chamber 5, electricity
Machine stator 10 is fixedly installed in bore of stator 6, and motor control panel 8 is installed in control chamber 7.Bore of stator 6 can be with that with control chamber 7
This connection, and motor control panel 8 can be arranged on stator 10.In radial directions, rotor 9 is located at the outer of motor stator 10
Side.
As shown in Fig. 2 motor casing 3 may include lateral wall and internal insulation wall.Lateral wall can be axially extend it is big
Cause cylinder-like structure so that motor casing 3 has generally cylindrical exterior contour, and is opened wide respectively two ends.Motor
The internal insulation wall of shell 3 separates the cylindrical space that lateral wall limits, so that described in internally the side of dividing wall is formed
Rotor chamber 5, opposite side form the bore of stator 6.Wherein, the bore of stator 6 is connected with the control chamber 7, and the two is by motor
Shell 3 and end cap 4 are limited jointly, and bore of stator 6 is kept apart with both control chambers 7 and rotor chamber 5.
As shown in Fig. 2 in the water pump 1 that the utility model is proposed, it is preferably so that bore of stator 6 and control chamber 7 are filled
There is casting glue 11.The casting glue 11 can be epoxy resin, polyurethane or silica gel etc..But the species of casting glue 11 is not limited to
This.
Preferably so that the bore of stator 6 and the control chamber 7 are by 11 complete embedding of casting glue, i.e. casting glue 11 exists
It is completely filled with bore of stator 6 and control chamber 7.Meanwhile the part in bore of stator 6 and control chamber 7 can be coated by casting glue 11 completely,
Specifically, the part such as the stator module in bore of stator 6, motor control panel 8 in control chamber 7 is coated by casting glue 11 completely.
By the embedding of casting glue 11, following technique effect can be brought.
First, good sealing function can be realized.By by bore of stator 6, control chamber 7 and its internal part completely by embedding
Glue 11 coats, even if water enter in bore of stator 6 and control chamber 7 stator winding that can not also touch intracavitary, motor control panel 8 or
Miscellaneous part, reach and be fully sealed.
Secondly, the radiating of stator module and motor control panel 8 is advantageous to.In the running of water pump 1, stator module and electricity
Machine control panel 8 is easy to produce heat, and wherein larger parts of caloric value, as mos manages (metal-oxide-semiconductcor field effect
Answer transistor), stator coil etc. it is straight with the intracavity liquid of water pump 1 because layout requirement can not be accomplished to be close to the inwall of motor casing 3
Connect conduction heat.By the cladding of casting glue 11 in this programme, can effectively solve the parts heating of the remote inwall of motor casing 3
The larger and problem that can not shed in time.
As shown in Figures 2 and 4, embedding through hole 14 can be set on end cap 4, it is described fixed for casting glue 11 is incorporated into
In sub- chamber 6 and the control chamber 7.So, end cap 4 can be mounted together with motor casing 3 and then leading to casting glue 11
The embedding through hole 14 set is crossed on end cap 4 to pour into inside bore of stator 6 and control chamber 7.Alternatively, the embedding through hole 14 is arranged on
The center position of end cap 4, or near center location, in order to fill.
Preferably, the end cap 4, which is provided with, is projected into control chamber 7 and around the projective structure 13 of embedding through hole 14.End
The shape of the projective structure 13 of lid 4 is not limited to the shape shown in accompanying drawing, and it can be the substantially tubular around embedding through hole 14
Structure, the shape of cross section of tubular structure can be circular, square, rectangle, triangle, polygon etc..It is described convex
Going out structure 13 can be integrally formed with the end cap 4.
After casting glue 11 injects bore of stator 6 and control chamber 7, the projective structure 13 of end cap 4 is embedded to casting glue 11
It is interior.So, casting glue 11 is securely engaged and wrapped the projective structure 13 of end cap 4 so that end cap 4 is fixed to one with casting glue 11
Rise.
Preferably, as shown in figure 4, the projective structure 13 sets the prominent projection 16 in the oriented inside of embedding through hole 14.Example
Such as, the projective structure 13 may be provided with to one or more annular projections prominent inside embedding through hole 14.For with more
The situation of individual annular projection, multiple annular projections can be along projective structures 13 equidistantly or not equidistantly distributed.
By the projection 16, the bonding area of projective structure 13 and casting glue 11 can be caused to increase, so as to protrude knot
Structure 13 more firmly catches casting glue 11, and then causes end cap 4 to be difficult to disengage with casting glue 11.
When casting glue 11 is liquid, there is good flow behavior, (can be mixed again as needed by embedding through hole 14
Professional equipment vacuumize process means), liquid casting glue 11 can be full of whole bore of stator 6 and control chamber 7, wrap up well
The parts such as stator core, stator coil, motor control panel 8, and wrap up the projective structure 13 on end cap 4.When casting glue 11 solidifies
Afterwards, above-mentioned part and/structure form one by casting glue 11.Due to the integrative-structure that projective structure 13 is end cap 4, then end cap
4 are connected together securely by casting glue 11 and motor casing 3 and its part so that end cap 4 is difficult for drop-off.So, according to this reality
Ultrasonic bonding need not be carried out between motor casing 3 and end cap 4 as current conventional water pump with the water pump of new proposition.
As shown in Fig. 1,3,4, end cap 4 is also provided with least one detection through hole 15, is filled for being detected during embedding
The height of sealing 11, such as detected by infrared ray level detector.Preferably, as illustrated, the end cap 4 sets two
Individual detection through hole 15, described two detection through holes 15 can be positioned equidistantly in the both sides of embedding through hole 14.However, it is also possible to
Other quantity, the detection through hole 15 positioned at other positions are set.
Alternatively, after encapsulating process terminates, by the special equipment vacuumized, the bubble in casting glue 11 is taken out.
Generally, it is provided with the end cap 4 of water pump for establishing the contact pin electrically connected with the motor control panel 8.For
The scheme with contact pin with end cap 4, it is preferable that at least one be preferably provided at the contact pin in the detection through hole 15
Near, in order to during manufacture drain the air near contact pin only, avoid contact pin from nearby producing bubble.
Above-mentioned water pump 1 can be used for the cooling system of vehicle.Such as automobile engine is installed on near turbocharger, using
In the cooling of turbocharger.
The exemplary implementation side for the water pump that the utility model is proposed is described in detail above in reference to preferred embodiment
Formula, but it will be appreciated by those skilled in the art that on the premise of without departing substantially from the utility model theory, can be to above-mentioned specific
Embodiment makes a variety of modifications and remodeling, and can to the utility model proposes various technical characteristics, structure carry out a variety of groups
Close, and determined without departing from the scope of protection of the utility model, the scope of protection of the utility model by appended claim.
