Embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
In conjunction with referring to Fig. 1 to Fig. 3, as we know from the figure, the damping device of the motor of the present embodiment comprises the first beam 10 of the first side that is arranged on motor 100, the first axially extending bore 11 that offers the motor shaft of dodging motor 100 on the first beam 10, has the first hole group in the circumferential arranged outside of the first axially extending bore 11.
The first hole group on the first beam 10 comprises multiple the first shock relieve vents 31, and multiple the first shock relieve vents 31 being circumferentially uniformly distributed along the first axially extending bore 11.The first shock relieve vent 31 can be for being opened in the lip-deep blind hole that two of the first beams are oppositely arranged, phase his-and-hers watches are also oppositely arranged the lip-deep blind hole arranging, and the total depth of two blind holes that are oppositely arranged is at least the half of the thickness of the first beam 10, in the time that two blind holes are communicated with, the first shock relieve vent 31 forms through hole, can make the effect of the first shock relieve vent 31 reach best.
In a kind of preferred embodiment, the first shock relieve vent 31 is the mounting hole along the circumferential direction extending, the optimal number of the first shock relieve vent 31 is 2 to 6, for improving damping effect, the setting of mounting hole is taking the angle number of degrees between the adjacent edge of two adjacent mounting holes as 10 ° to 35 ° as good, and the distance between two camber lines of mounting hole is 1/4 to 1/2 being advisable of thickness of the first beam 10, taking 1/3 as best.
There are two the second hole groups that are oppositely arranged in the circumferential arranged outside of the first hole group, and two the second hole groups are corresponding one by one with the two ends of the first beam 10, second hole group is arranged on the first end of the first beam, and another the second hole group is arranged on the second end being oppositely arranged with first end.The second hole group comprises two the second shock relieve vents 32 that are oppositely arranged and the 3rd shock relieve vent 33 arranging between two the second shock relieve vents 32, the second shock relieve vent 32 and the 3rd shock relieve vent 33 are respectively and are arranged on two lip-deep blind holes that are oppositely arranged, and two the second hole groups are symmetrical arranged along the first axially extending bore 11.The second shock relieve vent 32 is connected and surrounds successively by three curved surfaces, wherein, the concave surface of first surface towards the concave surface of the first axially extending bore 11, the second curved surfaces towards the 3rd shock relieve vent 33, the concave surface of the 3rd curved surface is towards two other curved surface, and connection between three curved surfaces adopts round and smooth excessive mode.The blind hole of the second shock relieve vent 32 for being oppositely arranged, and the degree of depth of the second shock relieve vent 32 at least accounts for the more than 70% of thickness of the first shock absorber part, and the second shock relieve vent 32 damping effect the best when becoming through hole.The 3rd shock relieve vent 33 preferably be circular hole, the form that arranges of the 3rd shock relieve vent 33 is to be opened in the lip-deep blind hole that two of the first beams are oppositely arranged, and the total depth of two blind holes account for whole the first beam thickness 3/10 to 6/10 for good.
For convenience of the first beam 10 installation in use, it is coordinated with the connection bump being arranged on housing, the first beam 10 is fixed on housing, two ends of the first beam 10 are respectively arranged with installing hole 40.And, each installing hole 40 on the thickness direction of the first beam between two the 3rd shock relieve vents 33 of homonymy.
The damping device of the present embodiment also includes the second beam 20 of the second side that is arranged on motor 100, as shown in Figures 4 to 6, the second beam 20 is substantially identical with the structure of the first beam 10, difference is only, on the first surface of the second beam 20, be provided with join with motor 100 and be connected protuberance 50, in this connection protuberance 50, offer identical with effect with the structure of the second axially extending bore 21(and the first axially extending bore 11) dead in line and the 3rd axially extending bore 51 being communicated with the second axis through bore 21, the second beam 30 coordinates with motor 100 by the 3rd axially extending bore 51.Be arranged on the 3rd hole group on the second beam 20 the 4th shock relieve vent 34 structure and effect identical with the first shock relieve vent 31 of the first hole group, do not repeat them here.It should be noted that, owing to connecting the setting of protuberance 50, the 4th shock relieve vent 34 can only be for being arranged on the blind hole on the second surface of the second beam 20, and, the degree of depth of the 4th shock relieve vent 34 be the second beam thickness 7/10 to 9/10, such arranging can obtain best damping effect.The 5th shock relieve vent 35 of the 4th hole group on the second beam 20 and the setting of the 6th shock relieve vent 36 have identical structure and effect with the second shock relieve vent 32 of the second hole group on the first beam 10 and the setting of the 3rd shock relieve vent 33, are not repeating at this.For ease of the second beam 20 is fixed on housing, two ends of the second beam 20 are respectively arranged with installing hole 40.
The present invention also provides a kind of household electrical appliance, comprises housing 200, motor 100 and damping device according to the embodiment of household electrical appliance of the present invention, and motor 100 is arranged in housing 200 vacantly by damping device, and damping device is above-mentioned damping device.As shown in Figure 7, the housing 200 of the household electrical appliance of the present embodiment is respectively arranged with two connection bumps 210 on two inner surfaces that are relatively set with, and connection bump 210 on two inner surfaces is oppositely arranged.This connection bump 210 coordinates with the installing hole 40 on the first beam 10 and the second beam 20, the first beam 10 and the second beam 20 are fixed on to housing 200 inside, and in the first axially extending bore 11 of the first beam 10, be equipped with the first end of motor shaft, in the second axially extending bore 21 of the second beam 20 and the 3rd axially extending bore 51, be equipped with the second end of motor shaft, when the second beam 20 and the second beam 20 common cooperation, be arranged on unsettled being arranged in housing 200 of motor 100 between the first beam 10 and the second beam 20, and make between motor 100 and housing 200 as flexibly connecting.
The unsettled setting of motor 100, while making motor 100 that vibration occur directly and housing 200 come in contact, direct Vibration propagation between motor 100 and the housing 200 having cut off, only transmits the vibration of motor 100 to connection bump 210 by the first beam 10 and the second beam 20.The vibration of motor 100 is mainly manifested in axially and both direction radially, and wherein, the vibration of axial direction is out of shape and is consumed in the lower alternating bending of vibration by the basis of the first beam 10 and the second beam 20; The vibration of radial direction consumes and sponges by being arranged on the continuous distortion of the shock relieve vent on the first beam 10 and the second beam 20, and the setting of connection bump 210 also can be laid down the outside transmission of part twisting vibration.Under the cooperation of the first beam 10 and the second beam 20, the vibration of all directions that motor 100 can be produced in the time working is effectively consumed and isolates out by damping device, the vibration insulation and noise reduction of the complete machine of realization.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
