Fig. 1 is the blast of the sealing structure of the integrated driving device used for electric vehicle of one embodiment of the invention
Figure.Fig. 2 is the front view of the integrated driving device used for electric vehicle of one embodiment of the invention.Such as Fig. 1-2
Shown, the sealing structure that the present invention is provided is applied to the integrated driving device of electric automobile, the integrated drive
Dynamic device can include：The motor driven using electric current and the inverter changed to AC-to-DC electricity.
Procapsid 4, extruding housing 3 and back casing 1 to be constituted match somebody with somebody to merge to constitute successively successively with merging and closed
Motor housing.The housing can be as the shell of integrated driving device.The electronic vapour that the present invention is provided
The sealing structure of automobile-used integrated driving device, can integrate motor and inverter, save dress
With space, weight of equipment is reduced, the support for supporting inverter is saved, so as to manufacture is greatly reduced
Cost.
Inverter (not shown) is arranged in back casing 1, and it can include capacitance module and power mould
Block, capacitance module has the DC connecting end electrically connected with dc source；Power model its there is multiple
On-off circuit, DC input terminal and AC output terminal, direct-flow input end are electrically connected to dc source
(for example, Vehicular accumulator cell), AC output terminal is electrically connected to electric motor.On-off circuit will be from straight
The direct current that stream input is obtained is converted to alternating current, and is exported by ac output end.Inverter shell
Body (that is, back casing 1) encapsulates in the chamber formed by it power model and capacitance module.
The stator module of motor is provided with three AC input terminals at it towards one end of inverter, exchange
Input terminal sets the end downside of stator module.Correspondingly, inverter power model one end
Downside be provided with three AC output terminals, three AC output terminals are arranged so that inversion
After the completion of device and group of motors turn, three AC output terminals are direct with corresponding three AC input terminals
Contact, for example, be connected through a screw thread, welding, solder, solder brazing, riveting and Elastic Contact are connected
Together, and without using extra connecting line, this reduces manufacturing cost.
Because the drive device of integrated motor and inverter needs to cool down motor and inverter, because
This can design composition coolant channel 4-6 on procapsid 4, extruding housing 3 and back casing 1
Minor structure so that in procapsid 4, extruding housing 3 and after back casing 1 coordinates successively, in shell
Body is internally formed the coolant flow channel (that is, coolant channel 4-6) of closing.
As a kind of embodiment, as shown in figure 1, procapsid 4 can include：Protecgulum 4-1；With it is preceding
Cover integrally formed cylinder 4-2 and back seat 4-3；Wherein：The radial direction maximum radius value of protecgulum 4-1>Afterwards
The radial direction maximum radius value of seat 4-3>The radial direction maximum radius value of cylinder 4-2, the i.e. radial direction of protecgulum 4-1
Maximum radius value more than back seat 4-3 radial direction maximum radius value, and back seat 4-3 radial direction maximum half
Footpath radial direction maximum radius value of the value more than cylinder 4-2.For example, the radial direction of the extruding housing 3 is maximum
Radius value>The radial direction maximum radius value of back seat 4-3；Also, it is described extruding housing 3 radial direction maximum half
Footpath is worth<The radial direction maximum radius value of protecgulum 4-1.So, procapsid 4 can be linked in extruding housing
In 3, and cause back seat 4-3 through extruding housing 3 to carry out subsequent cooperation with back casing 1.
Based on this structure, the invention provides a kind of sealing structure of integrated driving device used for electric vehicle, can

In embodiments of the present invention, O-ring seal is employed, and uniqueness is formd on seal groove
Mechanism, as shown in fig. 4-5, in procapsid 4, extruding housing 3 and the respective outer side edges shape of back casing 1
Into seal groove, it is relatively reliable that this sealing belongs to the such sealing of delta seal (axially and radially).O
Type sealing ring is a kind of extrusion pressing type sealing, and the basic functional principle of extrusion pressing type sealing is sent out by seal
Raw elastic deformation, causes contact on sealing contact surface, and contact is more than sealed medium
Internal pressure, then do not leak, otherwise then leaks.
As shown in figures 1 and 3, procapsid has a shunting muscle in the coolant channel 4-6 at middle part
4-5, when coolant is flowed into from inverter, coolant flows for one week counterclockwise, then to delivery port position,
So form a cooling on a large scale.For example, the S-type edges of shunting muscle 4-5 are parallel to cylinder 4-2
Axial direction be arranged on the cylinder 4-2 between protecgulum 4-1 and back seat 4-3, so as to cooling agent be led to
Road 4-6 is separated so that cooling agent can enter along coolant channel 4-6 along a predetermined direction
Row circulation.
Further, since using design structure of the invention, the procapsid 4 and back casing of present invention design
1 can use extrusion process, and extruding housing 3 can use extrusion process.With in the prior art,
Generally entirely different by the way of sand casting housing forms coolant flow channel, prior art is complete by all runners
Portion is concentrated in a housing, and so as to increase manufacture difficulty, and the present invention uses this 3 parts
The scheme for constituting housing is many with respect to being simplified in technique for a housing completely casting, so as to improve
Yield rate.The problem that the sand casting process of prior art is present is easily to produce stomata during sand casting,
Coolant flow channel is caused to leak, yield rate is low.
The sealing structure of the integrated driving device a kind of used for electric vehicle of present invention design, can be to motor
Effectively sealed with the cooling body that inverter is integrated, and with relatively low manufacturing cost.
The above is only some embodiments of the invention, it is noted that for the art
For those of ordinary skill, under the premise without departing from the principles of the invention, some improvement can also be made
And retouching, these improvements and modifications also should be regarded as protection scope of the present invention.
