Referring to fig. 4 in conjunction with fig. 2 and 3, fig. 2 and 4 are views illustrating an embodiment of a damping assembly provided in the present application, wherein fig. 4 is an enlarged structural view of a portion a of the damping assembly shown in fig. 2.
In one embodiment provided herein, the vibration damping assembly 100 comprises a housing 110, a piston rod 120 and a damping unit 130, wherein the housing 110 is provided with a chamber 106, the housing 110 further has a top wall 103 and a bottom wall 104 arranged oppositely, the top wall 103 and the bottom wall 104 forming the chamber; the piston rod 120 is arranged through the top wall 103 and the bottom wall 104; the damping unit 130 is disposed between the top wall 103 and the bottom wall 104 and disposed to cover the piston rod 120, and the damping unit 130 has a moving space between the top wall 103 and the bottom wall 104, and the damping unit 130 is movable between the top wall 103 and the bottom wall 104.
Illustratively, the housing 110 further has a side wall 105, the side wall 105 is connected to the top wall 103 and the bottom wall 104, and a gap 107 is formed between the damping unit 130 and the side wall 105.
Specifically, in an embodiment provided in the present application, the piston rod 120 is inserted into the housing 110, the top wall 103, the bottom wall 104 and the side wall 105 are disposed in the chamber 106, and the annular damping unit 130 tightly fitted on the piston rod 120 is further disposed in the chamber 106.
The length of the damping unit 130 is smaller than the distance between the top wall 103 and the bottom wall 104, so that when the piston rod 120 is subjected to smaller vibration, the damping unit 130 tightly attached to the piston rod 120 can move up and down between the top wall 103 and the bottom wall 104 under the driving of the piston rod 120; meanwhile, the width of the damping unit 130 in the first embodiment of the present application is smaller than the distance between the side wall 105 and the piston rod 120, so that the damping unit 130 does not contact with the side wall 105 when the piston rod 120 drives the damping unit 130 to move up and down between the top wall 103 and the bottom wall 104.
The specific working principle is as follows: when the washing machine 300 rotates at a low speed and the vibration amplitude is large, the piston rod 120 drives the damping unit 130 to reciprocate between the top wall 103 and the bottom wall 104 under the influence of vibration, because the vibration amplitude is large, the damping unit 130 sleeved on the piston rod 120 contacts the top wall 103 and the bottom wall 104 during reciprocating motion, when the damping unit 130 contacts the top wall 103 or the bottom wall 104, if the washing machine 300 is still in a low-speed rotation stage and the vibration amplitude is still too large, the damping unit 130 will abut against the top wall 103 or the bottom wall 104, but the piston rod 120 still moves up and down under the influence of the vibration of the washing machine 300, and at this time, the damping unit 130 and the piston rod 120 generate friction force (namely, a damping state) to suppress the vibration of the washing machine 300; when the washing machine 300 is in a high-speed rotation state from a low-speed rotation state, the vibration amplitude of the washing machine 300 is small, and if the vibration damping assembly 100 is still in a damping state, the normal high-speed rotation of the washing machine 300 is affected, at this time, the damping unit 130 provided in the first embodiment of the present application still reciprocates between the top wall 103 and the bottom wall 104 under the driving of the piston rod 120, but does not contact the top wall 103 and the bottom wall 104, and since the width of the damping unit 130 is smaller than the distance between the side wall 105 and the piston rod 120, the damping unit 130 does not contact the side wall 105 (i.e., in a non-damping state) when reciprocating between the top wall 103 and the bottom wall 104, so that the problem that the working state of the washing machine 300 is affected by providing friction when the washing machine 300 is in a high-speed rotation state can be avoided.
For example, please refer to fig. 5 and fig. 6, wherein fig. 5 isbase:Sub>A second cross-sectional view of the damping assembly shown in fig. 1 alongbase:Sub>A directionbase:Sub>A-base:Sub>A, and fig. 6 is an enlarged structural view ofbase:Sub>A part B of the damping assembly shown in fig. 5.
Specifically, in another embodiment provided in the present application, the housing 110 further has a side wall 105, the side wall 105 connects the top wall 103 and the bottom wall 104, and the damping unit 130 abuts against the side wall 105. The length of the damping unit 130 is still smaller than the distance between the top wall 103 and the bottom wall 104, so that when the piston rod 120 is subjected to smaller vibration, the damping unit 130 tightly attached to the piston rod 120 can move up and down between the top wall 103 and the bottom wall 104 under the driving of the piston rod 120; however, in another embodiment of the present application, the width of the damping unit 130 is larger than the distance between the side wall 105 and the piston rod 120, so that the damping unit 130 can abut against the side wall 105, further causing the damping unit 130 to contact the side wall 105 and generate frictional damping with the side wall 105 when the piston rod 120 drives the damping unit 130 to move up and down between the top wall 103 and the bottom wall 104.
The specific working principle is as follows: when the washing machine 300 rotates at a low speed and the vibration amplitude is large, the piston rod 120 drives the damping unit 130 to reciprocate between the top wall 103 and the bottom wall 104 and rub against the side wall 105 under the influence of vibration, because the vibration amplitude is large, the damping unit 130 sleeved on the piston rod 120 can also contact with the top wall 103 and the bottom wall 104 during the reciprocating motion, when the damping unit 130 contacts with the top wall 103 or the bottom wall 104, if the washing machine 300 is still in a low-speed rotation stage and the vibration amplitude is still too large, the damping unit 130 can abut against the top wall 103 or the bottom wall 104, but the piston rod 120 still moves up and down under the influence of the vibration of the washing machine 300, and at the moment, the damping unit 130 can generate a strong frictional force (namely a large damping state) with the piston rod 120 to suppress the vibration of the washing machine 300; when the washing machine 300 is raised from the low-speed rotation state to the high-speed rotation state, the damping unit 130 provided in another embodiment of the present invention still reciprocates between the top wall 103 and the bottom wall 104 under the driving of the piston rod 120, but does not contact the top wall 103 and the bottom wall 104, and since the width of the damping unit 130 is greater than the distance between the side wall 105 and the piston rod 120, the damping unit 130 contacts the side wall 105 and generates a small friction force (i.e., a small damping state) when reciprocating between the top wall 103 and the bottom wall 104.
It should be noted that, both one embodiment (with damping state and without damping state) and another embodiment (with large damping state and small damping state) of the present application can be used in the vibration damping assembly 100 of the washing machine 300, and the corresponding embodiment may be selected according to the model and vibration mode of the washing machine 300.
Illustratively, the damping assembly 100 further includes a spring 140 and a spring mount 150, the spring mount 150 is disposed on the piston rod 120 and opposite the second housing 102, and the spring 140 is disposed between the second housing 102 and the spring mount 140.
Illustratively, the spring 140 supports the second housing 102 such that the damping unit 130 is spaced apart from both the top wall 103 and the bottom wall 104 by a gap.
Specifically, when the damping assembly 100 is not in the working state, the spring 140 is in the initial state and is disposed between the second housing 102 and the spring seat 150 and supports the housing 110; when the vibration damping assembly 100 is in an operating state, the spring 140 may be compressed downward to provide a damping force to the vibration damping assembly 100, further improving the vibration damping effect; the spring 140 may also be extended upward to limit the housing 110, so as to prevent the housing 110 from shaking too much upward and downward under the influence of vibration when the vibration damping assembly 100 is in operation.
Before the vibration damping assembly 100 is operated, the spring 140 is in an initial state and can support the second housing 102 such that the second housing 102 is in an initial position. At this time, the damping unit 130 is disposed between the top wall 103 and the bottom wall 104 and is provided with a gap having an equal distance from both the top wall 103 and the bottom wall 104, i.e., the first moving space 106A and the second moving space 106B. The existence of the first moving space 106A and the second moving space 106B can make the damping unit 130 have a space for moving up and down in the housing 110 when the vibration damping assembly 100 is in the initial working state, so as to avoid that when the vibration amplitude is small, the damping unit 130 abuts against the top wall 103 or the bottom wall 104 and provides a large damping force to affect the working state of the washing machine 300.
It should be noted that, in the embodiment of the present application, it is not limited whether the distances between the first moving space 106A and the second moving space 106B and the top wall 103 or the bottom wall 104 are equal, for example, the distances between the first moving space 106A and the second moving space 106B and the top wall 103 or the bottom wall 104 may not be equal, and only a space for the damping unit 130 to move up and down needs to be provided in the housing 110.
Specifically, in the embodiment of the present application, the damping unit 130 is an annular damping friction ring sleeved on the piston rod 120, wherein the damping friction ring is connected with the piston rod 120 in an interference fit manner, and the connection between the damping friction ring and the piston rod 120 is more secure by using the interference fit connection manner.
In the embodiment of the present application, there is also provided a friction suspension rod 200, which includes a first connecting portion 210, a damping assembly 100 and a second connecting portion 220, wherein the first connecting portion 210 is used for connecting to a washing machine cabinet 320, the damping assembly 100 is the damping assembly 100 mentioned above, and the second connecting portion 220 is used for connecting to a washing machine tub 310.
Also provided in the embodiments of the present application is a washing machine 300 comprising a washing machine tub 310, a washing machine cabinet 320, and the above-mentioned plurality of friction booms 200.
