One of.Under any circumstance, by with enough stiffness differences, to for installing electric assembly and may also realize various
The high rigidity of sealing effectiveness needs to decouple from the needs to vibrating the Low rigidity transmitted for reducing, just as wherein pacifying
The various pieces for filling body can be independently optimised the same.
As that will explain now, in the case where applying the present invention to vacuum cleaner, when passing through erecting device
When fixing body is to reduce the level of vibration transmission, additional advantageous effects are obtained.Under the particular case being previously mentioned, actually exist
During the work of utensil, electric motor assembly is under the influence of air inlet at installation body side surface, and electric motor assembly is in the direction of fixing body
On be pulled.Specifically, shell is provided with the hole for allowing air inlet, and the diameter in the hole is selected to be less than the outer straight of fixing body
Footpath and the interior diameter for being more than fixing body.It means that when electric motor assembly is applying pressure on fixing body, outside fixing body
Portion part is in electric motor assembly and limits and is extruded between the casing part in hole, and the interior section of fixing body is not in any form
Supported by shell.Therefore, in the case where fixing body has the regular situation of more or less constant mean rigidity in radial directions, peace
Dress body needs to have a certain degree of rigidity so that fixing body will not be excessively deformed under the influence of pressure, and cause peace
One or more parts of dress body will collapse and/or sealing function will be lost.As it was previously stated, this requirement is with wishing to pass through
The vibration transmission that fixing body reduces from electric motor assembly to shell contradicts.When applying the invention, it is preferred that not by shell
The interior section of the fixing body of covering includes connecting portion and the first motor contact site.With connecting portion have it is of a relatively high firm
Spend and the first motor contact site has relatively low rigidity, because the connecting portion and other parts of fixing body can have
For that can bear due to the displacement of electric motor assembly and the enough rigidity of caused negative pressure and pressure, therefore negative pressure allows to make
With on the core of electric motor assembly, the core is limited by the contact with the first motor contact site.On the contrary,
Under regular situation, whole fixing body is all deformed, and wherein negative pressure allows the larger core for acting on electric motor assembly, i.e., electric
The whole part not covered by shell of motivation component.Therefore, in the present case, the effect of negative pressure is restricted such that
Obtain the movement of electric motor assembly under the influence of negative pressure to be restricted, and be to offset by motor unit compared with conventional situation
Part is applied to pressure on fixing body and so that other parts of the fixing body in addition to the first motor contact site needs to have
The demand for having high rigidity is restricted, and this allows the more freedom of the structure of fixing body, will not damage the installation of fixing body
There is the local more possible scheme for reducing rigidity in the case of function and sealing function.
In the practical embodiments of the erecting device according to the present invention, the first motor contact site is more located at fixing body
Inside edge, wherein the second motor contact site have more than the first motor contact site diameter.In addition, the second motor
Contact site can be motor/shell contact site of combination for contacting shell on first axle direction and with first
Axis direction contacts electric motor assembly on opposite second axis direction.
In the case where the second motor contact site is the motor/shell contact site combined as described above, fixing body
It is preferably configured such that radial position of the axial motors support member on fixing body corresponds to the motor of combination/outer
Position of the radial centre lines in the region of shell contact site on fixing body, for contacting shell on the first axial direction.Such as
The region of motor/shell contact site of upper described combination can include a for example, at least flank.For example, wrapped in the region
In the case of including two flanks mutually extending side by side, radial centre lines as described above are the centers of the combination of two flanks
Line, and therefore the radial centre lines extend (assuming that flank is similar) between flank.
As that will explain now, in the case that the present invention is applied to vacuum cleaner, axially electricity as described above
The radial position of motivation support member and the radial position for being used to contact the region of shell of the motor/shell contact site combined
Matching is related to additional advantageous effects.In normal conditions, occurred by the axial direction support of the electric motor assembly of fixing body right
Among the region that the position in the hole of air inlet should be allowed in shell.Therefore, the responsive to axial force of electric motor assembly is in this region
Fixing body on, but on the axial reaction force of shell effect fixing body in another area, i.e. fixing body and shell
Limit the region that the part in hole is in contact.Therefore so that fixing body tilts, and which increase the deformation of fixing body, the fixing body needs
To be compensated by selecting the specified level of rigidity.In the preferred embodiment of fixing body, axial motors support member tool
Have and be in contact as the similar radial position of regional center line for the part in the restriction hole with shell, to cause motor unit
The axial force of part and the reaction force acts of shell are similarly radially on position, and avoid the inclined tendency of fixing body.With
Conventional situation is compared, and this is to provide another factor for the possibility for reducing rigidity.
Nevertheless, axial motors support member as described above and the part for the restriction hole with shell connect
The center line in tactile region is mutually located what is be not required in the framework of the present invention.In view of with the possibility for reducing rigidity
Property, it is beneficial to be specifically mutually located, it is also possible to select another positioning for example to compensate pressure differential.
In the practical embodiments of the erecting device according to the present invention, the second motor contact site includes pressing along its circumference
According to the region of the different radial rigidities of pattern, wherein the region of of a relatively high radial rigidity and the region of relatively low radial rigidity
Alternately, wherein axial motors support member is disposed in the region of the relatively low radial rigidity of the second motor contact site
In.In this case, it is assumed that according to the erecting device of the present invention it is anticipated that to apply, on electronic in electric device
The vibration of thermomechanical components is coupled to the improvement of the degree in fixing body, and two opening positions of electric motor assembly are touched in fixing body
Realize, i.e., second on the first contact position and the second motor contact site on foregoing first motor contact site connects
Position is touched, the position of the axial rigidity of the installation of electric motor assembly is realized especially by being contacted with axial motors support member
Put.It is disposed in based on axial motors support member in the region of the relatively low radial rigidity of the second motor contact site
The fact, relative to the region of no relatively low radial rigidity to cause ledge only from the area with average radial rigidity
For the situation of domain extension, the transmission from the second contact position to the vibration of the electric motor assembly of shell is reduced.In view of axial direction
The fact that motor support part extends from the region with relatively low radial rigidity, obtains axially at the second contact position
The situation that rigidity and radial rigidity are decoupled, this allow that to the both types rigidity in the erecting device according to the present invention
Optimization.Even if axial motors support member extends from the region of relatively low radial rigidity, due to relatively low radial rigidity
The fact that replace with of a relatively high radial rigidity, thus avoid part be diametrically movable to it is undesirable largely
Situation.

And/or the shape of selection flank controls rigidity.Selected on latter, it is noted that flank can be caused with straight line
Or extended with curve.It is in any case possible to optimize the flank to realize appropriate radial rigidity in a given case,
It is applied to certain types of electric motor assembly and certain types of electric device, the electric device includes shell, motor unit
Part will be installed in the shell by the erecting device according to the present invention.
Assuming that the second motor contact site is provided with foregoing flank, flank and axial motors support member are present
It is feasible in the same side of fixing body, wherein axial motors support member can be disposed in from along the second of fixing body
The periphery of motor contact site sees, between flank without contacting the position of flank.This is that axial rigidity is decoupled in fixing body
With an example of the mode of radial rigidity.In fixing body, the decoupling by flank and axial motors support member it
Between realize enough spaces and realize, this can be by selecting suitable path length between flank and part control.
For example, in order to increase path length, the end for the material that can be connected to fixing body in part sets groove.
Preferably, the axial rigidity of the first motor contact site is less than connecting portion and the axial direction of axial motors support member
Rigidity.In this case, the vibration for further reducing the electric motor assembly at the first contact position is passed to fixing body
Degree.Fixing body can be configured to have enough axial rigidities at the second contact position to be used for by rights
Electric motor assembly is installed.On axial rigidity, it is to be noted however that if the second motor contact site is firm including different radial directions
