Description
Technical field
The present invention relates to electric automobile, more particularly to a kind of electric automobile of power supply cassette installation.
Background technology
Electric automobile is to pass through power supply（Battery）It is powered.Existing power supply is bolted on automobile
On vehicle frame, therefore convenience during installation is poor.
The content of the invention
The invention provides a kind of electric automobile of power supply cassette installation, solve bolt connection and come present in fixed power source
Installation inconvenience the problem of.
Above technical problem is that solved by following technical proposal：A kind of electric automobile of power supply cassette installation, including
Power supply, it is characterised in that be also supported on the electricity provided with some including power supply supporting case and connecting pin detaching structure, the power supply
Support feet on the supporting case of source, the support feet are provided through the connecting pin of the roof of the power supply supporting case, the connecting pin
The inner be provided with some resilient barbs for preventing connecting pin from deviating from the power supply supporting case, the connecting pin detaching structure includes setting
The motor that the stripper plate, screw mandrel and drive screw for having some extruded holes rotate, the extruded hole are set in described correspondingly
On the inner of connecting pin, the resilient barb is between the stripper plate and the roof of power supply supporting case, the same institute of screw mandrel
It is parallel and be threaded on the stripper plate to state connecting pin.The technical program, power supply are to be supported on outside power supply mounting box
The open installation of row, good heat dissipation effect.Connecting pin is set to be alignd correspondingly then with the hole on power supply supporting case during installation
Pass through, resilient barb through power supply supporting case roof after flick and clasp joint in power supply supporting case and cause power supply from
It is enough to remove.When needing to remove power supply, rotated by motor drive screw, screw mandrel driving roof of the stripper plate towards power supply supporting case
One end, the extruded hole extruding resilient barb of stripper plate cause barb to shrink, and power supply supporting case can be passed through when barb is retracted to
Draw power supply that connecting line is separated with power supply supporting case behind hole on roof outside.The technical scheme, which presses, i.e. can
In connection, than existing bolt connection for, it is quick and convenient.
Preferably, moved outwardly provided with drive connection pin between the inner of the connecting pin and the bottom wall of power supply supporting case
And resilient barb is caused to hold out against the support spring on the inner surface of the roof of the power supply supporting case.It can either make it that barb is same
Power supply supporting case roof holds out against and improves fixed effect, while when resilient barb can take off from power supply supporting case in unloading process
Convenience when support spring can play a part of synchronously ejecting, removing power supply so as to improve connecting pin when going out.
Preferably, the motor includes motor casing, external stator, internal rotor and motor shaft, the both ends of motor casing are provided with end
Lid, by ball bearings on the end cap, the internal rotor is provided with motor shaft connecting hole, institute at the both ends of the motor shaft
The both ends for stating internal rotor refer to connecting hole provided with some connections, and the connection refers to circumferentially distributed axle of the connecting hole along motor shaft connecting hole
To extension, the motor shaft is made up of two segmentations, and one end of the segmentation is by the ball bearings in the end cap
The upper, other end is located in the motor shaft connecting hole in a manner of gap coordinates, the segmentation be provided with it is some correspondingly
The connection that the connection refers in connecting hole is located in refer to.
Its basic structure of motor includes motor casing, external stator, internal rotor and motor shaft, and the both ends of motor casing are provided with lid
Plate, by ball bearings on the cover board, internal rotor is provided with motor shaft connecting hole at the both ends of motor shaft, and motor shaft is designed as comparing
Big more and then by large-tonnage the press of motor shaft connecting hole extrudes by force and motor shaft is inserted into motor shaft connecting hole
Interior, the two in extrusion process is deformed and is snapped together realization and transmits moment of torsion.Internal rotor and motor shaft by it is existing with
When upper usual mode is attached, separates internal rotor and motor shaft is inconvenient.
The technical program by design along rotating shaft axially distribution connection refer to connecting hole be connected refer to realize internal rotor and
The connection of motor shaft, change the existing usual fixed form being pressed together by tight fit so that assembling internal rotor and
Extruded during motor shaft without press, it is easily laborsaving during assembling and also laborsaving when separating, because now rotating shaft and motor shaft
Not relying on friction caused by deformation, engagement realizes transmission in other words, between connection refers to connecting hole and connection refers to
Frictional force is without too big.
Preferably, the connection refers to forms pad to link together with internal rotor iron core by soldering, the electricity
It is provided with arbor connecting hole and drives described two cut springs segmented apart.The mode of soldering, during dismounting during fusion welding contact
The temperature needed is low.Cut spring is designed, will can be segmented apart after pad fusing so that connection refers to connecting hole and connection
Separating between finger so that extract more convenient when connection refers to.
Present invention additionally comprises pad fatigue to delay unit, and the both ends of the cut spring respectively pass through a pad
Fatigue delays unit to be linked together with the segmentation, and the pad fatigue delays unit to include being arranged in internal rotor iron core
The annular cylinder circumferentially extended along motor shaft connecting hole, one end of the annular cylinder is provided with the piston of annular, the other end is set
Have it is some circumferentially distributed slide opening is radially extended along motor shaft connecting hole, the slide opening is located at the madial wall of the annular cylinder
On, the slide opening interior sealing slidably connects crushing block, forms liquid storage cylinder between the crushing block and piston, in the liquid storage cylinder

On the end face of the segmentation, the hole wall of the motor shaft connecting hole is provided with along the axially extending strip of motor shaft connecting hole for support
The avoid holes of shape, the pin stretch out through the avoid holes.When motor works namely when internal rotor rotates, crushing block produces centrifugation
Power and towards moving in liquid storage cylinder, and pressure is produced to the liquid in liquid storage cylinder, the pressure passes to piston and drives piston to move
Dynamic, piston produces squeezing action to cut spring and offsets a part of cut spring degree and act on by pushing away post push and block bar, pin
The elastic force of segmentation, is segmented that the elastic force for the cut spring being subject to is small, and the power for passing to pad and tearing pad also reduces, from
And play the effect for delaying pad fatigue.The longer rotating speed of accounting of the technical scheme then motor working time is more fast, delays to weld
The effect of joint fatigue is better.
Preferably, the pad fatigue delays unit also to include the support block in the motor shaft connecting hole,
The cut spring is supported on the pin by the support block.Cut spring can be conveniently realized with all pins
All abut together.
Preferably, between the internal rotor and cover plate by plane bearing support together.Interior turn of existing motor
The axial float of son is completed by supporting the ball bearing of motor shaft, easily causes ball bearing damage or ball bearing
Come off from cover plate.The technical program can effectively prevent internal rotor from producing axial float.
Preferably, the plane bearing be supported on it is described connection refer on.It is convenient during layout.
