Shake pad 100, and the end face of the first flange 30 in motor cushion blocking 100 is provided with annular convex platform 31, in electric machine assembly 202
In installation process, the mounting hole 11 of the motor cushion blocking 100 passed through by fastener 203 (such as screw) locks electric machine assembly 202
It is close to and is connected to electric machine support 201, wherein fastener 203 is pressed in annular convex platform 31 and is formed by installation tooth 313, so that convex annular
Platform generates compressive deformation, since annular convex platform 31 forms multiple installation teeth 313, so that motor cushion blocking 100 is in its axial direction more
Flexible compression deformation easy to form, so in the operational process of electric machine assembly 202, the vibration that electric machine assembly 202 generates more is held
It easily is weakened counteracting in the compressive deformation process of motor cushion blocking 100, then the vibration that electric machine assembly 202 generates is easily detected by electricity

The lower noise of vibration and generation.
As a preferred embodiment, the annular convex platform 31 surround the opening periphery of the mounting hole 11, and convex annular
Outer diameter of the outer diameter of platform 31 less than the first flange 30.By the way that annular convex platform 31 to be surrounded on to the opening periphery of mounting hole 11, tight
During firmware locking, annular convex platform 31 can abut to the component (stud of screw in such as fastener 203 across mounting hole 11
Part), annular convex platform 31 can be so supported across the component of mounting hole 11, annular convex platform 31 with pass through mounting hole 11
Gap between component is smaller, then in extrusion process, annular convex platform 31 can be promoted to generate the shape in 100 axial direction of motor cushion blocking
Become, and because electric machine assembly 202 is installed on electric machine support 201 using hang, then the vibration quilt in 202 axial direction of electric machine assembly
Deformation process in 100 axial direction of motor cushion blocking is weakened, and effect of vibration and noise reduction is promoted.
Further, multiple 311 uniform intervals of through slot settings.Be thusly-formed multiple installation teeth 313 be also it is of uniform size,
The deformation of so each installation generation of tooth 313 is more uniform, then effect is more preferable during vibration damping.
In order to further promote effectiveness in vibration suppression, the range of the wall thickness d1 of this programme annular convex platform 31 is 2mm~4mm, when
When the wall thickness d1 of annular convex platform 31 is less than 2mm, although annular convex platform 31 is easy to produce deformation, its structural strength is weaker, in ring
Damaged damage is easy in the long-term use process of shape boss 31.When the wall thickness d1 of annular convex platform 31 is greater than 4mm, then annular convex platform
31 are not likely to produce axial deformation, and effectiveness in vibration suppression reduces.The range of the wall thickness d1 of annular convex platform 31 is set as 2mm~4mm by this programme,
So that annular convex platform 31 takes into account deformability and structural strength, effectiveness in vibration suppression is so promoted.
In the case where annular convex platform 31 is that above-mentioned wall thickness is arranged, this programme subtracts in order to further enhance annular convex platform 31
Vibration effect, the size that this programme defines axial direction extension of the through slot 311 along cylindrical body 10 is the depth h1, h1 of through slot 311
Range be 2mm~4mm.This programme is by setting 2mm~4mm for the depth dimensions of through slot 311, so that 31 institute of annular convex platform
The multiple installation teeth 313 formed take into account structural strength and deformability, can reach better effect of vibration and noise reduction.
This programme has also done structure improvement in the first flange 30, extremely referring once again to Fig. 1 to promote effect of vibration and noise reduction
Fig. 4, the first flange of this programme 30 are also formed with multiple grooves 33 away from the end face of the second flange 50, multiple 33 spacer rings of groove around
The annular convex platform 31.
This programme is by forming multiple grooves 33 the first flange 30 is recessed, so that the axial direction of motor cushion blocking 100
Deformability is further promoted, and is cooperated with above-mentioned annular convex platform 31, and effect of vibration and noise reduction greatly promotes.
Further, the arc-shaped setting of each groove 33, multiple grooves 33 are evenly spaced on.In this way, the first flange 30
Deformation process in various pieces deformation quantity more evenly, the structural strength of the first flange 30 is also higher.
This programme is in order to further ensure that the first flange 30 takes into account deformability and stabilized structure double effects.One
In preferable scheme, the size for defining axial direction extension of the groove 33 along cylindrical body 10 is the depth h2 of groove 33, h2's
Range is 1mm~3mm；And/or defining the groove 33 along the size that the radial direction of the cylindrical body 10 extends is groove
The range of 33 width d2, d2 are 1mm~3mm.
When the depth h2 of groove 33 is too deep or the width d2 of groove 33 is oversized, the structural strength of the first flange 30
Poor, when the width d2 of the depth h2 of groove 33 or groove 33 are undersized, then deformability is insufficient.
In order to further promote the effectiveness in vibration suppression of motor cushion blocking 100, motor cushion blocking 100 is with wall thickness range
The cylindrical body 10 and 3 range of thickness d of 0.25mm~0.5mm is the first flange 30 of 3mm~6mm, in electric machine assembly 202

Be close to and be connected to electric machine support 201, in the process, due to the present invention by the first flange 30 with a thickness of 3mm~6mm so that motor
Cushion blocking 100 axially has suitable decrement, the spacing and electric machine assembly 202 of motor cushion blocking 100 and fastener 203
It is in OK range with the spacing of electric machine support 201, the vibration in 202 operational process of electric machine assembly passes through motor cushion blocking
100 barrier weakens, it is difficult to be transferred to electric machine support 201, so reach vibration and noise reducing purpose.When the of motor cushion blocking 100
When the thickness of one flange 30 is less than 3mm, during fastener 203 is locked, since motor cushion blocking 100 generates compression, motor
Cushion blocking 100 and the spacing and electric machine assembly 202 and the spacing of electric machine support 201 of fastener 203 are too small, then electric machine assembly
The vibration generated in 202 operational process is easy to be transferred to electric machine support 201 by motor cushion blocking 100, so that cooking machine 500
Body vibration noise is larger, when the thickness of the first flange 30 of motor cushion blocking 100 is greater than 6mm, locks in fastener 203
Cheng Zhong, after generating compression due to motor cushion blocking 100, the spacing and electric machine assembly 202 of motor cushion blocking 100 and fastener 203
It is slightly larger with the spacing of electric machine support 201, then hold between electric machine assembly 202 and electric machine support 201 in 202 operational process of electric machine assembly
It is also easy to produce swing, causes cooking machine 500 to vibrate excessive, noise is larger, while also increasing cost.
In addition, the wall thickness range of cylindrical body 10 is set as between 0.25mm~0.5mm, by cylindrical body 10 by motor
Component 202 and fastener 203 carry out elastic barrier, can so reduce in 202 operational process of electric machine assembly due to waving with it is tight
Firmware 203 or electric machine support 201 generate collision, and further achieve the purpose that buffering, vibration damping, noise reduction.When cylindrical body 10
Wall thickness be less than 0.25mm, electric machine assembly 202 be easy electric machine support 201 is transmitted these vibrations to because of swing in the process of running,
So that 500 overall noise of cooking machine is higher, when the wall thickness of cylindrical body 10 is greater than 0.5 millimeter, then need to open up biggish hole
Cylindrical body 10 is accommodated, and will also result in the cost increase of cooking machine 500.
Further, the end wall of the end wall of the first flange 30, the outer wall of cylindrical body 10 and the second flange 50 surrounds peace
Tankage (does not indicate).The present embodiment mounting groove (not indicating) in width (i.e. the first flange 30 in 100 axial direction of motor cushion blocking
The distance between second flange 50) it is suitable with the length in the axial direction of the pilot hole 2021 on electric machine assembly 202, and install
Gap is equipped between the bottom wall (i.e. the outer wall of cylindrical body 10) and the inner wall of pilot hole 2021 of slot (not indicating), specifically,
Cylindrical body 10 be located between the outer wall of the part in pilot hole 2021 and the inner wall of pilot hole 2021 spacing range be 0.5mm~
1.5mm.Then in 202 operational process of electric machine assembly, in vibration processes electric machine assembly 202 because gap presence so that motor group
Part 202 has certain swing cushion space to be not easy rigid collision due to swing with fastener 203, such electric machine assembly
202 vibration can be as few as possible be transmitted to electric machine support 201, then further promoted effect of vibration and noise reduction.
Further, this programme can also be provided with connecting column 2011 in electric machine support 201, and connecting hole 2012 is formed in described
Connecting column 2011, connecting column 2011 is inserted in pilot hole 2021 in assembling process, i.e. cylindrical body 10 is located at pilot hole 2021
Interior part is located between the inner wall of pilot hole 2021 and the outer wall of connecting column 2011, setting in this way, so that connection knot
