Description
Technical field
The invention belongs to the design fields of washing machine damping, and in particular to a kind of buffer of washing machine sunpender
Structure.
Background technology
When washing machine works, outer barrel motor, clothing, washings active force under, outer barrel can be generated and rocked, to one side
It tilts, if the centrifugal force that washing machine operating generates is larger, angle of inclination is also larger, so that the outer barrel of washing machine is likely to
There is the situation with babinet collision, noise increase when causing the washing machine to work, and it is susceptible to the shock between babinet and outer barrel
Damage problem influences the service life of each component of washing machine.
In order to which outer barrel rocks magnitude of inclination when reducing washing machine operating, generally select and shock-absorbing suspension rod is set to play buffering
Effect, as shown in Figure 1, sunpender generally comprises the body of rod 1 ', upper suspension ball 2 ' and lower suspension ball positioned at body of rod upper and lower side
3 ', spring 4 ' is fixedly connected with below lower suspension ball, and when washing machine rocks generation inclination, the spring of inclined side can be forced
Contracting, and the spring of its symmetrical side meeting stress stretches, generating elastic acting force by symmetrical spring carries out the angle of inclination
/V prevents that inclined external drum angle is excessive, avoids colliding between outer barrel and casing of washing machine, causes larger noise, influences
The service life of body.
But the spring of the shock-absorbing suspension rod lower part of traditional structure forms is outside, and after long-time use, spring is susceptible to
It gets rusty damage, and therefore the friction plate connected between spring and lower suspension ball can also come off, then influence the damping effect of sunpender.
And hanging rod structure of the prior art is relative complex, and parts are more, it is necessary to pay attention to being installed in place, inconvenient, work effect
Rate is relatively low.
In view of problem above, it is necessary to propose a kind of new hanging rod structure, while sunpender cushioning effect is met, keep away
Exempt from the damage of elastomeric element and come off, meet the needs of washing machine long-time service, reduce use cost, effectively optimize sunpender knot

Buffer gear in the present embodiment is the tubular structure that outer diameter gradually increases from top to bottom, internal to be hollow, and
And the buffer gear is in integrally curved configuration from top to bottom, simulates the structural form of spring, and in specific processing, it is desirable that it is soft
The structural form of property supporting layer is consistent with rigid support skeleton, therefore after the completion of injection, the inside and outside wall of buffer gear is song
Linear structure.Wherein buffer gear outer diameter can unanimous between the higher and lower levels or part it is consistent etc., and the overall structure form of buffer gear
Also it is determined on a case-by-case basis, is not limited herein.
When outer barrel of washing machine shakes trend one side and tilts, the buffer gear forced compression of the side, the buffering with its symmetrical side
Then stress is elongated for mechanism, realizes damping effect.
Preferably, rigid support skeleton 41 is multiple single stents (such as Fig. 3) for being uniformly arranged for one week around sunpender, each stent
Between be arranged at intervals, flexible support layers 42 are coated on each bracket outer.It can only be set in specific shaping in stent periphery flexible
Supporting layer is still spaced form between each stent, is equivalent to one layer of antioxidation coating of external cladding in stent.
In order to further improve the structural strength of buffer gear in the present embodiment, therefore it is soft to be selected in interval filling between stent
Property supporting layer, i.e., be also molded with flexible support layers between adjacent two stands, such flexible support layers be connected with multiple stents to be formed around
The overall structure that sunpender is set.
In practical operation, can not also select integrally formed mode, can be one step ahead mold with certain planform
Flexible support layers, after rigid support skeleton interted in flexible support layers realize, concrete mode is not limited.
In addition, connecting portion 43 is extended with upwards at the top of buffer gear, in the lower suspension ball 3 of the connecting portion 43 insertion sunpender
Fixed, connecting portion is the integrally formed part of flexible support layers, when mechanism is delayed in injection molding can integrated injection molding go out the connection
Portion, the connecting portion substitute conventional friction piece function, and in laundry machine dehydration, resonance stage reduces complete machine oscillation.Effectively optimization simultaneously
Hanging rod structure, reduces the amount of parts on sunpender, and simplified assembling process is conveniently installed in place.
Preferably, the outer rim of connecting portion can be in cone columnar structures, facilitate and be quickly assembled between connecting portion and lower suspension ball
Position, corresponding, 3 bottom of lower suspension ball forms the groove (not shown) being embedded in for connecting portion 43, when outer barrel of washing machine rocks,
Lower suspension ball can be moved up and down with rotation connection；Buffer gear further includes support base 44, and buffer gear bottom passes through branch
Support pedestal is fixed on the end of sunpender, with moving up and down so that buffer gear is realized compression or is stretched into for connecting portion
Row damping.
The invention also discloses a kind of washing machine sunpender, including the body of rod 1 and positioned at body of rod both ends upper suspension ball 2 with
Lower suspension ball 3, sunpender upper end are connected by upper suspension ball 2 with casing of washing machine, downrod lower end by lower suspension ball 3 with
Outer barrel of washing machine connects, and the buffer gear, sunpender end insertion buffering are provided with below the lower suspension ball of an at least sunpender
It is in-house, when washing machine generation is rocked, by the elastic acting force damping of buffer gear.
Under normal conditions, the sunpender in washing machine uses four, and currently preferred four boom foots are respectively provided with buffering
Mechanism effectively improves damping effect.It also optionally sets and buffers in symmetrically arranged two boom foots in specifically used
Mechanism, specifically used form are not limited.
The operation principle of the present invention is as follows：
Buffer gear is fixed on by support base 44 on the end of sunpender, the connecting portion 43 at the top of buffer gear is inserted into
Fixed in the bottom groove of lower suspension ball 3, upper suspension ball is fixed with casing of washing machine, lower suspension ball and washing machine outside
Bucket is fixed, generates and rocks when washing machine is run so that lower suspension ball can move up and down stretching with rotation connection or compression is soft
Property supporting layer and rigid support skeleton, when outer barrel of washing machine shakes trend one side and tilts, the buffer gear forced compression of the side, with
The buffer gear of its symmetrical side then elongate by stress, realizes damping effect.
Embodiment 2
Remaining is same as Example 1, the difference is that, rigid support skeleton is the whole knot set for one week around sunpender
Structure, flexible support layers are separately formed on the integrally-built interior outside.It is specific that monoblock steel plate bending shaping can be used just
Rubber material, is being taken shape in the outside of rigid support skeleton by property support frame by way of in-mould injection.For rigid branch
The structure type of support bone frame can be a variety of, not be limited herein.
The invention discloses a kind of buffer gear of washing machine sunpender, by using integrally formed rigid support skeleton with
