[0036] To solve the above technical problems in the prior art, that is, to solve the problems such as abnormal noise generated after the assembly or durable operation of the shock absorber 100 in the existing laundry treatment equipment, this embodiment provides a shock absorber 100 for a laundry treatment equipment and a laundry treatment equipment.
[0037] First, this embodiment provides a shock absorber 100 for a laundry treatment equipment, as Figures 1-5 shown. The shock absorber 100 includes a shock absorber assembly 10 and a connecting pin 16. First connecting holes perpendicular to the length direction of the shock absorber assembly 10 are provided at both ends of the shock absorber assembly 10, and vibration isolation pads 14 are provided in the first connecting holes; the connecting pin 16 is inserted into the first connecting holes, and the connecting pin 16 is further used for being inserted into the second connecting holes of the double-ear mounting bracket 21 to mount the shock absorber assembly 10 into the double-ear mounting bracket 21; wherein, the vibration isolation pads 14 are in interference fit with the connecting pin 16 and deform to separate the double-ear mounting bracket 21 and the wear-resistant bushing 15.
[0038] The shock absorber assembly 10 is a friction damping shock absorber 100, which is connected between the outer tub and the housing of the laundry treatment equipment and consumes the vibration energy generated by the outer tub through its own structure, so as to slow down the movement of the outer tub relative to the cabinet, and thus achieve the purpose of shock absorption.
[0039] To achieve the connection between the shock absorber 100 and the outer shell and the outer cylinder, first connection holes are provided at both ends of the shock absorber assembly 10, and vibration isolation pads 14 are accommodated in the first connection holes. Among them, the first connection holes are through holes with a circular cross-section, the vibration isolation pads 14 are all cylindrical, and annular grooves are provided on the outer peripheral surface of the vibration isolation pads 14. The vibration isolation pads 14 are inserted into the first connection holes and are limited and fixed to the shock absorber assembly 10 through the annular grooves. The connection pin 16 can pass through the central hole of the vibration isolation pad 14 and be tightly fitted with the vibration isolation pad 14 to achieve the connection between the connection pin 16 and the shock absorber assembly 10. At the same time, a double-ear mounting bracket 21 is provided on the outer cylinder or the box body of the laundry treatment device. The double-ear mounting bracket 21 includes two connection ears arranged at intervals, and each connection ear is provided with a second connection hole. The two second connection holes of the same double-ear mounting bracket 21 are coaxially arranged. The connection pin 16 can pass through the second connection hole of the connection ear to achieve the connection between the connection pin 16 and the double-ear mounting seat, and further achieve the connection with the outer cylinder or the box body provided with the double-ear mounting seat.
[0040] During use, the connection pin 16 first passes through one connection ear, and then passes through the vibration isolation pad 14 of the shock absorber assembly 10 and the other connection ear, so as to achieve the connection between the shock absorber assembly 10 and the outer shell and the outer cylinder. During assembly, the vibration isolation pad 14 and the connection pin 16 are in interference fit, so that the connection strength between the shock absorber assembly and the laundry treatment device can be improved. Furthermore, not only can the sliding friction between the vibration isolation pad 14 and the connection pin 16 be reduced, and the friction abnormal noise be reduced, but also the bearing capacity for torque, axial force or the combined load of the two can be improved, and it can work more reliably under impact vibration loads. In addition, during interference fit, when restricted in the radial direction, the axial direction of the vibration isolation pad 14 deforms and extends, and thus can be adapted to the connection ear of the double-ear mounting seat, so as to further improve the constraint on the shock absorber assembly 10 and prevent the connection position from having an increased vibration problem.
[0041] In the shock absorber 100 for the laundry treatment device provided in this embodiment, by arranging the vibration isolation pads 14 in the first connection holes at both ends of the shock absorber assembly 10, and connecting the connection pin 16 inserted into the vibration isolation pads 14 with the double-ear mounting bracket 21 in the outer cylinder or the box body, the connection between the shock absorber assembly and the laundry treatment device is achieved. At the same time, since the vibration isolation pad 14 and the connection pin 16 are in interference fit, when the shock absorber assembly 10 is connected to the double-ear mounting bracket 21 on the box body or the outer cylinder of the laundry treatment device through the connection pin 16, the connection strength between the shock absorber assembly 10 and the laundry treatment device can be improved, and thus the anti-impact vibration ability at the connection position can be improved, and the friction abnormal noise between the connection structures can be reduced, etc. During interference fit, when restricted in the radial direction, the axial direction of the vibration isolation pad 14 deforms and extends, and thus can be adapted to the connection ear of the double-ear mounting seat 21, so as to further improve the constraint on the shock absorber assembly 10 and prevent the connection position from having an increased vibration problem.
[0042] In one embodiment, the width of the vibration isolation pad 14 along its axial direction is H1. The double-ear mounting bracket 21 includes two connecting ears which are spaced apart and have second connecting holes. The distance between the two connecting ears is H2. The interference amount between the connecting pin 16 and the vibration isolation pad 14 is G, and G≤H2 - H1≤1.6G.
[0043] Specifically, the deformation range of the vibration isolation pad 14 affects the connection state between the vibration isolation pad 14 and the double-ear mounting seat. If the deformation is too small, the vibration isolation pad 14 cannot be abutted against the connecting ear, and thus the axial constraint of the double-ear mounting seat on the vibrator assembly cannot be achieved. If the deformation is too large, it will impact the double-ear mounting seat, thereby affecting the service life of the connection structure. Therefore, it is necessary to limit the deformation range of the vibration isolation pad 14. The deformation of the vibration isolation pad 14 is affected by the interference amount G between the connecting pin 16 and the vibration isolation pad 14. The larger the interference amount G is, the greater the change amount of the axial width H1 of the vibration isolation pad 14 after installation is, and the greater the installation difficulty between the connecting pin 16 and the vibration isolation pad 14 is. Therefore, considering the above factors and through actual test verification, the value range of G is set as G≤H2 - H1≤1.6G. For example, H2 - H1 = G, H2 - H1 = 1.1G, H2 - H1 = 1.2G, H2 - H1 = 1.3G, H2 - H1 = 1.4G or H2 - H1 = 1.5G, etc. In this way, the double-ear mounting seat 21 can play a role in constraining the shock absorber assembly 10, and the impact force between the vibration isolation pad 14 and the connecting ear can also be reduced.
[0044] By limiting the relationship between the interference amount and the axial length of the vibration isolation pad 14 and the width between the two connecting ears, the axial deformation of the vibration isolation pad 14 can be abutted against the side surface of the connecting ear, and further, the double-ear mounting bracket 21 can play a role in constraining the shock absorber assembly 10 in the front and rear directions, and further reduce the vibration of the shock absorber assembly 10 in the axial direction of the connecting pin 16.
[0045] In one embodiment, the shock absorber assembly 10 further includes a wear-resistant bushing 15, and the wear-resistant bushing 15 is arranged between the vibration isolation pad 14 and the connecting pin 16.
[0046] Specifically, the wear-resistant bushing 15 is in a cylindrical shape. It is inserted into the vibration isolation pad 14 and is in close fit with the vibration isolation pad 14 and the connecting pin 16. In this way, the wear of the vibration isolation pad 14 can be reduced, thereby increasing the service life of the vibration isolation pad 14.
[0047] In one embodiment, the central hole of the vibration isolation pad 14 is a counterbore, the end of the wear-resistant bushing 15 is provided with a flange, the flange is located in the large hole of the counterbore, and a gap is formed between the end face of the flange and the end face of the vibration isolation pad 14. On the one hand, this can make the axial length of the wear-resistant bushing 15 less than that of the vibration isolation pad 14, so that the deformed vibration isolation pad 14 can wrap the end of the wear-resistant bushing 15 to separate the wear-resistant bushing 15 from the connecting ear of the double-ear mounting bracket 21. Furthermore, it can avoid the friction between the wear-resistant bushing 15 and the double-ear mounting bracket 21 after installation and during long-term use, thereby reducing abnormal noises in the laundry treatment device and further improving the user experience. On the other hand, the wear-resistant bushing 15 can be limited by the cooperation of the counterbore and the flange, thus preventing the wear-resistant bushing 15 from axially moving during assembly and abutting against the connecting ear, which further ensures the accuracy of the wear-resistant bushing 15 and the vibration isolation pad 14 during assembly and ensures the separation of the wear-resistant bushing 15 from the double-ear mounting bracket 21.
[0048] Specifically, counterbores are formed at both ends of the central hole of the vibration isolation pad 14, and both can be adapted to the flange. During assembly, the end of the connecting pin 16 is inserted into the wear-resistant bushing 15 from one end of the flange.
[0049] In one embodiment, the shock absorber assembly 10 includes a friction rod 12, a damping cylinder 11 and a bracket 13. One end of the friction rod 12 extends into the damping cylinder 11 from one end of the damping cylinder 11 and is slidably connected to the damping cylinder 11. The other end of the friction rod 12 is elastically connected to one end of the bracket 13. The other ends of the damping cylinder 11 and the bracket 13 are provided with first connection holes.
[0050] Specifically, one end of the friction rod 12 is inserted into the damping cylinder 11 and is slidably connected to the damping cylinder 11. In this way, the shock absorber assembly 10 can consume a part of the vibration energy generated by the outer cylinder through the relative movement of the friction rod 12 and the damping cylinder 11. At the same time, the other end of the friction rod 12 is elastically connected to the bracket 13, so that a part of the vibration energy generated by the outer cylinder can be further consumed by elastic deformation.
[0051] In one embodiment, a third connection hole is provided at the other end of the friction rod 12 relative to the damping cylinder 11, and an elastic sleeve 17 is provided in the third connection hole; the bracket 13 includes a first splicing member 131 and a second splicing member 132. Plug-in portions 133 that are in interference fit with the elastic sleeve 17 are provided on both the first splicing member 131 and the second splicing member 132, and the two plug-in portions 133 are inserted into and locked from both sides of the elastic sleeve 17.
[0052] Specifically, the elastic sleeve 17 has the same shape and material as the vibration isolation pad 14, and the installation method of the elastic sleeve 17 and the third connection hole is also the same as that of the vibration isolation pad 14 and the first connection hole. The insertion part 133 is columnar and has a diameter slightly larger than the inner diameter of the elastic sleeve 17. Along the axial direction of the insertion part 133, mounting holes are provided on each insertion part 133. During assembly, the insertion parts 133 of the first splicing member 131 and the second splicing member 132 are inserted into the elastic sleeve 17 from both ends of the third connection hole and are locked and fixed by threaded connectors. In this way, not only the connection of the first splicing member 131 and the second splicing member 132 is realized, but also the elastic connection between the bracket 13 and the friction rod 12 is realized.
[0053] In one embodiment, through holes are also provided on the first splicing member 131 and the second splicing member 132, and the two through holes are combined to form the first connection hole.
[0054] Specifically, the central axis of the through hole is arranged parallel to the central axis of the insertion part 133, and the two through holes are combined towards each other along the direction of their central axes to form the first connection hole.
[0055] In one embodiment, a limiting cap 161 is formed at one end of the connecting pin 16, and a groove is provided on the side wall of the other end. A spring buckle 162 is provided on the inner wall of the groove, and the spring buckle 162 is arranged to protrude outside the groove in the natural state and retract inside the groove under pressure.
[0056] In this way, during the process of connecting the first connection hole at the end of the shock absorber 100 to the double-ear mounting bracket 21 through the connecting pin 16, when the connecting pin 16 passes through the wear-resistant bushing 15 and the second connection hole of the double-ear mounting bracket 21, the elastic buckle retracts inside the groove. After the connecting pin 16 passes through the wear-resistant bushing 15 and the second connection hole of the double-ear mounting bracket 21, the limiting cap 161 and the elastic buckle are respectively stuck at the outer ends of the two connecting ears to prevent the connecting pin 16 from falling off.
[0057] In one embodiment, a tip 163 with a gradually decreasing diameter facing outwards along the length direction is formed at the end of the connecting pin 16 where the elastic buckle is provided. This tip 163 can play a good guiding role during the installation of the shock absorber 100, and thus it is easier for the connecting pin 16 to pass through the wear-resistant bushing 15 and the second connection hole.
[0058] The present utility model also provides a laundry treatment device, which includes a cabinet, an outer tub provided in the cabinet, and the shock absorber 100 according to any one of the above; a double-ear mounting bracket 21 with a second connection hole is provided on the cabinet;
[0059] One end of the shock absorber 100 is connected to the double-ear mounting bracket 21 through a connecting pin 16 inserted into the first connection hole, and the other end of the shock absorber 100 is connected to the outer tub through a connecting pin 16 inserted into the first connection hole.
[0060] The laundry treatment device provided in this embodiment uses the above shock absorber 100. Thus, when the connecting pin 16 passes through the first connection hole and the second connection hole to connect the shock absorber 100 to the outer cylinder or the cabinet of the laundry treatment device, it can effectively improve the abnormal noise problem caused by assembly or durability deformation, thereby improving the user experience.
[0061] The number of shock absorbers 100 is an even number, and all the shock absorbers 100 are symmetrically arranged in pairs with respect to the vertical plane where the axis of the outer cylinder is located. In this way, by the symmetrical arrangement in pairs, the force on the shock absorbers 100 is more balanced, so as to more effectively achieve the shock absorption purpose of the laundry treatment device. Optionally, the number of shock absorbers 100 is 4, and they are evenly arranged on both sides of the axis of the outer cylinder.
[0062] In one embodiment, the cabinet is further provided with a mounting seat 20. The mounting seat 20 is provided with two double-ear mounting brackets 21 spaced along its length direction, and the third connection holes of the two double-ear mounting brackets 21 are coaxially arranged.
[0063] Specifically, the mounting seat 20 is strip-shaped and is connected to the cabinet by bolts, or the mounting seat 20 is welded to the cabinet. Along the length direction of the mounting seat 20, the two double-ear mounting seats 20 are spaced on the mounting seat 20 in a manner that the third connection holes are coaxially arranged. In this way, the two shock absorbers 100 on the same side of the axis of the outer cylinder can be spaced and connected to the same mounting seat 20.
[0064] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
