Description
Technical field
The present invention relates to a kind of electric drive unit with pole shell and electronic device case.
Background technology
From a kind of motor known to the A1 of DE 10 2,012 222 683, it is for example with the pole cover being made of metal.In the pole
The socket component being made of plastics axially is disposed with cover, is disposed with the material shape by being capable of conduction again on the socket component
Into cap.Here, cap is tensioned as pole cover is pressed from both sides by multiple steel springs, so as to which three components are fixed to one another.When shell is prevented
When closing, in such embodiment, each potted component is needed between different components water.Such three
Mingzhi arranges（Metal-plastic-metal）Interconnection technique it is comparatively laborious and especially enabled in extreme vibrational loading
Such connecting portion is untied, so as to which the shell can not seal.
The content of the invention
Shell is included according to the electric drive unit of the present invention, wherein, it is adjacent each other to be configured with three axial directions being made of metal
The case member connect.Here, pole shell（The stator and rotor of electro-motor are disposed with the pole shell）Directly with electronic installation shell phase
Even, the electronic device case is configured with metallic walls completely except grafting port.In order to which electronic installation is assembled described more easily
In electronic device case, the electronic device case is constructed in two style, wherein, the first case member is attached to using axially open sidepiece
Same the second axially open case member.After three shell elements being made of metal are connected, the electric drive unit is in reality
Encapsulated completely by metal cage on border, on the one hand the metal cage forms electromagnetic shielding well, and on the other hand can be excellently
In the shell caused heat export to surrounding enviroment.In addition, such metal-back mechanically stably constructs very much, so as to
Electric drive unit can bear big vibrations, and the shell will not blow-by.
By the measure enumerated in preferred embodiment and other embodiments, the feature that provides in the present invention has been drawn
Favourable modification and improvement project.It has been achieved in that especially high stability：That is, material connects between single shell element
Construct connecting portion with closing.Preferably, shell element melting welding or soldering each other, wherein, the connecting sewing is not when interrupting
Very simply can completely sealed it construct.It is especially suitable in terms of manufacturing technology, perform two using identical method
Connection procedure.So as to which, the shell is extremely stable and sealing, when not only pole shell and the first case member of electronic device case but also first
The melting welding or during soldering each other of case member and the second case member of electronic device case.
Here, at least one case member of two axial directions of the electronic device case can be very in cost advantageously by steel
Plate is made.Such steel plate can suitably be moulded in technology by deep-draw or bending ram.If use herein
Special steel, or to galvanized steel, then thus, it is possible to which the shell is effectively protected for corrosion.
Preferably, at least one described two axial case members are made of aluminum, so that the thermal conductivity for ensureing especially good goes out.This
Aluminium-case member of sample can be manufactured very simply by pressure casting method or spray to cast, wherein, while can construct with big
The cooling element on surface.In a preferred embodiment, departing from the pole shell second electronic device-case member by aluminium
Construction.First case member（It is arranged between pole shell and second electronic device-case member）Preferably as by steel plate shape
Into the deep-draw part of peviform manufacture.
, being capable of structured approach in its unlimited edge if described two case members construct to shell shape in principle
Orchid, described two case members are enabled to be connected with each other in the flange.Here, two case members or only one case member energy
Enough there is flange.By the structural scheme of the shell shape of the case member, these case members have circular around rotor axis
Perisporium, the stretching, extension of its axial direction can be selected correspondingly according to for the volume needed for electronic unit respectively.It is if described two
Case member melting welding or soldering each other, then two flanges directly axially against each other are on the one hand enabled to carry out material engagement ground
Be connected with each other, optionally, the perisporium that the axial direction of one of case member stretches can cover be attached to it is therein another
It is connected with each other on the flange of case member and by means of circular soldered or solder joint.
, also can be very cosily larger by the way that separating plane is constructed in electronic device case transverse to rotor axis
Circuit board is embedded into the described first or second case member, and next the hermetically locking each other of described two case members.
