Fig. 1 shows a schematic structural view of an electric machine in an embodiment of the invention; FIG. 2 shows an exploded view of the motor shown in FIG. 1; for the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.
Referring to fig. 1 and 2, an embodiment of the present invention provides a motor 100, which includes a motor cover 10, a motor body 20, and a plurality of elastic vibration damping members 30.
The motor body 20 is installed in the motor cover 10, and the elastic vibration damping members 30 are circumferentially spaced along the motor body 20 and clamped between the motor cover 10 and the motor body 20.
The motor 100 is used as a power source of the dust collector and can drive the impeller to rotate at a high speed so as to instantaneously generate negative pressure in the dust collector and further realize the suction of dust and dirt. Specifically, the motor 100 may be fixedly coupled to the housing of the cleaner through the motor cover 10.
In this way, when the motor 100 operates, the motor body 20 vibrates due to high-speed rotation, the vibration of the motor body 20 presses the elastic vibration damping members 30 interposed between the motor body 20 and the motor cover 10, the elastic vibration damping members 30 deform due to the pressing, and the elastic vibration damping members 30 absorb the vibration energy after being deformed, thereby achieving a vibration damping effect. According to the motor 100 disclosed by the invention, the vibration directly transmitted to the motor cover 10 from the motor body 20 can be weakened through the plurality of elastic vibration reduction parts 30, so that the effects of noise reduction and comfortable holding are achieved, and the user experience is good.
In some embodiments, the motor 100 further includes an annular vibration damping mounting member 40, the annular vibration damping mounting member 40 being sandwiched between the motor cover 10 and the motor body 20, an outer circumferential wall of the annular vibration damping mounting member 40 being provided with a plurality of elastic vibration damping members 30. The plurality of elastic vibration damping members 30 are disposed on the annular vibration damping mounting member 40 to be clamped between the motor cover 10 and the motor body 20, and the contact surface between the elastic vibration damping members 30 and the motor body 20 is increased, so that the elastic vibration damping members 30 can be clamped more stably and reliably, and on the other hand, the structure of the motor body 20 can be prevented from being changed when the elastic vibration damping members 30 are disposed on the motor body 20, for example, grooves are formed on the outer wall of the motor body 20 or protrusions are formed to fix the elastic vibration damping members 30 in advance.
In some embodiments, the annular vibration damping mount 40 is a resilient annular vibration damping mount 40. In this way, the vibration of the motor body 20 can be absorbed by the co-extrusion deformation of the elastic ring-shaped vibration damping mounting member 40 and the plurality of elastic vibration damping members 30, so that the vibration damping effect of the motor 100 is improved.
Specifically, the annular vibration damping mount 40 is integrally formed with the plurality of elastomeric vibration damping members 30. In this way, the annular damper mounting member 40 and the plurality of elastic damper members 30 can be more easily mounted on the motor body 20 and the motor cover 10, and the annular damper mounting member 40 and the plurality of elastic damper members 30 can be easily manufactured.
In some embodiments, the annular vibration dampening mount 40 is an interference fit with the motor body 20. So for the vibration of motor body 20 is absorbed by annular damping installed part 40 completely, avoids producing the installation clearance and leading to the damping effect poor between annular damping installed part 40 and the motor body 20.
In some embodiments, the inner peripheral wall of the annular damper mount 40 is provided with a first mating member 41, the outer peripheral wall of the motor body 20 is provided with a second mating member 21, and the first and second mating members 41, 21 cooperate to axially fix the annular damper mount 40 relative to the motor body 20. In this way, the annular vibration reduction member 40 is prevented from being influenced by vibration to generate axial play during vibration of the motor 100, thereby preventing vibration reduction failure.
Specifically, the first fitting member 41 includes a groove, and the second fitting member 21 includes a projection that matches the groove. The structure is simple and the matching is convenient. In other embodiments, the first fitting 41 may include a protrusion, and the second fitting 21 may include a groove for engaging the protrusion.
In some embodiments, in order to further secure the annular vibration damping mounting member 40 in the axial direction, the outer circumferential wall of the motor body 20 is provided with a step portion 22, the motor cover 10 includes a cover body 11 and a rear cover 12, and two ends of the annular vibration damping mounting member 40 in the axial direction respectively abut against the step portion 22 and the rear cover 12.
In some embodiments, the output end of the motor body 20 abuts against the cover 11, and further, the output end of the motor body 20 abuts against the cover through the elastic sealing element 50, and one end of the motor body 20, which is axially away from the output end, is fixed to the rear cover 12.
In some embodiments, a hollow portion is disposed inside the elastic damping member 30, and the hollow portion is disposed to allow the elastic damping member 30 to be easily deformed when the elastic damping member 30 is subjected to vibration of the motor body 20, and in addition, to facilitate installation of the elastic damping member 30 and the annular damping mounting member 40 between the motor body 20 and the motor cover 10.
As shown in fig. 3, further, the hollow portion includes a through hole 31, and the through hole 31 extends along the longitudinal direction of the elastic damping member 30. The through hole 31 penetrating the elastic damping member 30 is formed to facilitate and uniform deformation of the elastic damping member 30 when the elastic damping member is subjected to vibration of the motor body 20. Specifically, the through hole 31 is circular in shape, and the through hole 31 is disposed offset to the motor cover 10 with respect to the motor body 20.
In some embodiments, the thickness of the elastic vibration damping member 30 tends to decrease in a direction from the motor body 20 to the motor cover 10.
It should be understood that the tendency of the thickness of the elastic vibration damping member 30 to decrease in the direction from the motor body 20 to the motor cover 10 means that the thickness of the elastic vibration damping member 30 has a tendency to decrease as a whole from the motor body 20 to the motor cover 10, but is not necessarily a linear decrease or a gradual decrease. For example, the sectional shape of the elastic vibration damping member 30 is trapezoidal, semicircular arc, or the like.
In some embodiments, the elastomeric vibration damping member 30 extends in a direction parallel to the axial direction of the motor body 20. Thus, the vibration of the motor body 20 can be uniformly reduced by the elastic damping member 30, and the damping effect is improved. Specifically, the elastomeric damping member 30 extends in a first direction, the first square being axially coplanar with the motor body 20.
Based on the same inventive concept, the invention also provides a dust collector, which comprises a shell and the motor 100, wherein the motor 100 is arranged on the shell 100.
Specifically, the motor 100 is mounted inside the housing 100, and the motor cover 10 of the motor 100 is fixed inside the housing 100.
The motor 100 and the dust collector provided by the embodiment of the invention have the following beneficial effects:
when the motor 100 operates, the motor body 20 rotates at a high speed to generate vibration, the vibration of the motor body 20 extrudes the elastic vibration damping members 30 clamped between the motor body 20 and the motor cover 10, the elastic vibration damping members 30 are extruded and deformed, and the elastic vibration damping members 30 can absorb vibration energy after being deformed, so that a vibration damping effect is achieved. According to the motor 100 and the dust collector, the vibration directly transmitted to the motor cover 10 from the motor body 20 can be weakened through the elastic vibration reduction parts 30, so that the effects of noise reduction and comfortable holding are achieved, and the user experience is good.
