Detailed implementation manners

[0042] It should be noted that, without conflict, the embodiments in the present application and the technical features in the embodiments can be combined with each other. The detailed description in the detailed implementation manners should be understood as an explanatory illustration of the purpose of the present application and should not be regarded as an improper limitation to the present application.

[0043] An embodiment of the present application provides a clothes processing device, which includes a drum and a door cover assembly provided in an embodiment of the present application.

[0044] The clothing processing device in the embodiment of the present application can be a washing machine, a washing machine, or a washer-dryer. Exemplarily, the clothing processing device is a pulsator washing machine.

[0045] The drum is provided with a clothes processing chamber, that is, the clothes are washed in the clothes processing chamber.

[0046] The door cover assembly is provided on the drum body and is used to open or close the laundry processing chamber. The laundry placement opening 300a is connected to the laundry processing chamber. Laundry is placed in or taken out of the laundry processing chamber through the laundry placement opening 300a.

[0047] In the related art, taking a pulsator washing machine as an example, the door cover of the pulsator washing machine usually closes too quickly and makes a lot of noise during the process of opening and closing due to the lack of damping at the rotating shaft.

[0048] The embodiment of the present application also provides a door cover assembly, see Figure 1 , comprising a workbench 300, a door cover 200, and a damping device 100 provided in an embodiment of the present application. The workbench 300 is provided with a clothing placement opening 300a. The door cover 200 is mounted on the workbench 300 and is rotatably connected to the workbench 300 for opening and closing the clothing placement opening 300a. The damping device 100 is mounted on the workbench 300 and / or the door cover 200, and the door cover 200 is fixedly connected to the rotating member 20 of the damping device 100.

[0049] Here, during the closing process of the door cover 200 , the gravity of the door cover 200 itself is balanced by the damping force inside the damping device 100 , so that the door cover 200 falls slowly, avoiding noise when contacting the workbench 300 .

[0050] The door cover 200 is mounted on the workbench 300 and is rotatably connected to the workbench 300 to open or close the clothing placement opening 300a. In other words, the door cover 200 is rotated to open or close the clothing placement opening 300a.

[0051] The damping device 100 is arranged on the workbench 300 and / or the door cover 200, which means that the damping device 100 can be arranged on the workbench 300, or on the door cover 200, or on both the workbench 300 and the door cover 200.

[0052] The door cover 200 is fixedly connected to the rotating member 20 of the damping device 100 , so that when the door cover 200 rotates to open or close, the rotating member 20 is driven to rotate.

[0053] See also Figures 1 to 10, embodiments of the present application provide a damping device 100. The damping device 100 includes a housing 10, a rotating member 20, a transmission member 30, and a damping unit 40. The housing 10 is provided with a receiving cavity 10a having an opening 10b. The rotating member 20 includes a connecting portion 22 and a rotating shaft 21 connected to the connecting portion 22. The connecting portion 22 is disposed in the receiving cavity 10a, and the rotating shaft 21 extends out through the opening 10b for connecting to a door cover 200 so that the rotating member 20 can rotate relative to the housing 10 during the opening and closing rotation of the door cover 200. The transmission member 30 is disposed in the receiving cavity 10a, and the rotating member 20 can drive the transmission member 30 to slide between a first position and a second position during rotation. The damping unit 40 is disposed in the receiving cavity 10a. During the process of the transmission member 30 sliding from the first position to the second position, the damping force generated by the damping unit 40 on the transmission member 30 increases.

[0054] The damping device 100 can be disposed on the workbench 300 and / or the door cover 200 through the housing 10. That is to say, the housing 10 can be used to connect to other components of the door cover assembly, such as connecting to the workbench 300 and / or the door cover 200, and can also be used to provide an installation space for other components of the damping device 100 and protect other components of the damping device 100.

[0055] Please refer to Figures 2 to 10 , the rotating member 20 includes a connecting portion 22 and a rotating shaft 21 connected to the connecting portion 22. The rotating shaft 21 extends out through the opening 10b for connecting to the door cover 200 so that the rotating member 20 can rotate relative to the housing 10 during the opening and closing rotation of the door cover 200. The connecting portion 22 is disposed in the receiving cavity 10a for cooperating with the transmission member 30 so that the rotating member 20 can drive the transmission member 30 to slide between a first position and a second position during rotation.

[0056] During the process of the transmission member 30 sliding from the first position to the second position, the damping force generated by the damping unit 40 on the transmission member 30 increases. That is to say, the damping unit 40 is used to provide a damping force for the rotating member 20 and the transmission member 30, and thus can be used to provide a damping force during the closing process of the door cover 200 to slow down the rotation speed of the door cover 200 and achieve a damping effect.

[0057] Exemplarily, when the transmission member 30 is in the first position, the door cover 200 is in the state of opening the clothing placement port 300a. When the transmission member 30 is in the second position, the door cover 200 is in the closed state of closing the clothing placement port 300a. During the process of the door cover 200 switching from the open state of opening the clothing placement port 300a to the closed state of closing the clothing placement port 300a, the door cover 200 drives the rotating member 20 to rotate through the rotating shaft 21. The rotating member 20 drives the transmission member 30 to slide from the first position to the second position, and the damping force generated by the damping unit 40 on the transmission member 30 gradually increases, thereby slowing down the rotation speed and closing speed of the door cover 200.

[0058] Here, during the closing process of the door cover 200, the gravity of the door cover 200 itself is balanced by the damping force inside the damping device 100, so that the door cover 200 slowly falls to avoid generating noise when contacting the workbench 300.

[0059] The damping device 100 provided by the embodiment of the present application, the rotating member 20 of the damping device 100 includes a connecting portion 22 and a rotating shaft 21 connected to the connecting portion 22. The connecting portion 22 is disposed in the accommodating cavity 10a, and the rotating shaft 21 extends out through the opening 10b for connecting with the door cover 200 so that the rotating member 20 can rotate relative to the housing 10 during the rotation and opening / closing process of the door cover 200. The rotating member 20 can drive the transmission member 30 to slide between the first position and the second position during the rotation process. In this way, the door cover 200 drives the rotating member 20 to rotate during the rotation and opening / closing process, and the rotating member 20 drives the transmission member 30 to slide between the first position and the second position by rotation. By setting the damping unit 40, during the process of the transmission member 30 sliding from the first position to the second position, the damping force generated by the damping unit 40 on the transmission member 30 increases. Therefore, the door cover 200 needs to overcome the damping force generated by the damping unit 40 on the transmission member 30 during the descending process, so that the descending speed of the door cover 200 is slow, which is beneficial to reducing the closing sound of the door cover 200 and improving the user experience. [[ID=](7)

[0060] It should be noted that the specific structure of the damping unit 40 is not limited here.

[0061] In some embodiments, please refer to Figures 3 to 10 , the damping unit 40 includes an elastic member. During the process of the transmission member 30 sliding from the first position to the second position, the elastic member undergoes elastic deformation, and during the process of the transmission member 30 sliding from the second position to the first position, the elastic member recovers its elastic deformation.

[0062] The specific type of the elastic member is not limited here. For example, it can be a spring 41 such as a tension spring, a torsion spring, a compression spring, etc., or other structural members that can undergo elastic deformation.

[0063] During the process of the transmission member 30 sliding from the first position to the second position, the elastic deformation amount of the elastic member gradually increases, and the damping force generated on the transmission member 30 also gradually increases. Therefore, elastic potential energy is stored during this process. During the process of the transmission member 30 sliding from the second position to the first position, the elastic potential energy is released, and the elastic deformation amount gradually decreases. At this time, the door cover 200 just opens to the preset fully open position, and during the opening process of the door cover 200, the restoring elastic force of the elastic member applies a driving force to the transmission member 30, driving the transmission member 30 to slide towards the first position, which is beneficial for the user to open the door cover 200 and improves the user experience.

[0064] In some embodiments, please refer to Figures 3 to 10 , the damping unit 40 includes a linear damper 42. The linear damper 42 is used to provide a damping force along the axis direction of the linear damper 42. The elastic member is a spring 41, and the spring 41 is sleeved on the outer periphery of the linear damper 42.

[0065] The spring 41 is, for example, a coil spring 41.

[0066] That is to say, by simultaneously setting the linear damper 42 and the spring 41 in the damping unit 40, it is beneficial to increase the damping force generated on the transmission member 30 while improving the structural compactness of the damping unit 40. When the transmission member 30 is in the first position, when the door cover 200 switches from the open state of opening the clothing placement opening 300a to the closed state of closing the clothing placement opening 300a, the door cover 200 drives the rotating member 20 to rotate through the rotating shaft 21, and the rotating member 20 drives the transmission member 30 to slide from the first position to the second position. The linear damper 42 and the spring 41 are arranged at one end of the transmission member 30 far away from the rotating member 20. The linear damper 42 can provide a damping force along the axis direction of the linear damper 42, and the damping force generated by the damping unit 40 on the transmission member 30 gradually increases. At the same time, the transmission member 30 compresses the spring 41 to store elastic potential energy in the spring 41, further slowing down the rotation speed and closing speed of the door cover 200.

[0067] It should be noted that there are various ways to set the linear damper 42, which are not limited here.

[0068] Exemplarily, please refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 , in some embodiments, one end of the linear damper 42 close to the opening 10b contacts the transmission member 30, and the end far away from the opening 10b contacts the cavity wall of the accommodation cavity 10a. One end of the spring 41 close to the opening 10b contacts the transmission member 30, and the end far away from the opening 10b contacts the linear damper 42 or the bottom wall 10d of the housing opposite to the opening 10b.

[0069] One end of the linear damper 42 close to the opening 10 b contacts the transmission member 30 to provide a damping force for the transmission member 30 .

[0070] Illustratively, a receiving groove is provided on a side of the transmission member 30 facing the linear damper 42 , and the linear damper 42 extends into the receiving groove. The receiving groove can limit the linear damper 42 , thereby improving the reliability of the damping device 100 .

[0071] One end of the linear damper 42 away from the opening 10 b contacts the bottom wall 10 d of the housing opposite to the opening 10 b , that is, the linear damper 42 is clamped between the transmission member 30 and the bottom wall 10 d of the housing to provide damping force for the transmission member 30 .

[0072] The spring 41 is sleeved on the outer circumference of the linear damper 42. The end of the spring 41 close to the opening 10b contacts the end face of the transmission member 30, and the end away from the opening 10b contacts the bottom wall 10d of the shell. That is, the spring 41 is clamped between the transmission member 30 and the bottom wall 10d of the shell to provide damping force for the transmission member 30.

[0073] The end of the spring 41 away from the opening 10b contacts the linear damper 42 or the bottom wall 10d of the housing opposite to the opening 10b. This means that the end of the spring 41 away from the opening 10b may contact the linear damper 42 (see Figure 3 and Figure 7 ), or it may be in contact with the bottom wall 10d of the housing (see Figure 4 and Figure 8 ).

[0074] In other embodiments, see Figure 5 、 Figure 6 、 Figure 9 as well as Figure 10 The end of the spring 41 near the opening 10b contacts the transmission member 30, and the end away from the opening 10b contacts the bottom wall 10d of the housing. The end of the linear damper 42 near the opening 10b contacts the transmission member 30, and the end away from the opening 10b contacts the end of the spring 41 away from the opening 10b.

[0075] In this embodiment, the spring 41 is clamped between the transmission member 30 and the bottom wall 10 d of the housing to provide a damping force for the transmission member 30 .

[0076] One end of the linear damper 42 close to the opening 10b contacts the transmission member 30 , and the other end away from the opening 10b contacts the other end of the spring 41 away from the opening 10b . For example, the linear damper 42 is arranged inside the spring 41 and contacts the spring 41 .

[0077] It should be noted that there are many ways for the linear damper 42 to contact the spring 41 .

[0078] Exemplarily, please refer to Figure 6 and Figure 10 , the tail of one end of the spring 41 far from the opening 10b is bent and extended towards the inner ring of the spring 41 to form a limiting portion 41a, and one end of the linear damper 42 far from the opening 10b contacts the limiting portion 41a.

[0079] By providing the limiting portion 41a, the spring 41 is used to limit the linear damper 42 in the middle of the inner ring of the spring 41. One end of the linear damper 42 far from the opening 10b contacts one end of the spring 41 far from the opening 10b through the limiting portion 41a.

[0080] That is to say, in this embodiment, the linear damper 42 is arranged in the middle of the inner ring of the spring 41. One end of the linear damper 42 close to the opening 10b and the spring 41 both contact the transmission member 30. One end of the spring 41 far from the opening 10b contacts the bottom wall 10d of the housing, while one end of the linear damper 42 far from the opening 10b contacts one end of the spring 41 far from the opening 10b through the limiting portion 41a.

[0081] Here, the tail of one end of the spring 41 far from the opening 10b is bent and extended towards the inner ring of the spring 41 to form a limiting portion 41a. The linear damper 42 is arranged inside the spring 41, and one end far from the opening 10b contacts one end of the spring 41 far from the opening 10b through the limiting portion 41a. In this way, the linear damper 42 can be pre-assembled inside the spring 41 first, and then the pre-assembled parts of the linear damper 42 and the spring 41 are assembled into the housing, which improves the assembly efficiency, is conducive to realizing automatic assembly, and further improves the production efficiency and reduces the labor cost.

[0082] Exemplarily, please refer to Figure 5 and Figure 9 , one end of the spring 41 far from the opening 10b shrinks to form a necking portion 41b, and one end of the linear damper 42 far from the opening 10b contacts the necking.

[0083] By providing the necking portion 41b at one end of the spring 41 far from the opening 10b, the linear damper 42 is limited in the middle of the inner ring of the spring 41, and the linear damper 42 can contact the wall of the accommodating cavity 10a through the necking portion 41b.

[0084] That is to say, in this embodiment, the linear damper 42 is arranged in the middle of the inner ring of the spring 41. One end of the linear damper 42 close to the opening 10b and the spring 41 both contact the transmission member 30. One end of the spring 41 far from the opening 10b contacts the bottom wall 10d of the housing, while one end of the linear damper 42 far from the opening 10b contacts one end of the spring 41 far from the opening 10b through the necking portion 41b.

[0085] Here, one end of the spring 41 far from the opening 10b is provided with a reduced diameter portion 41b for restricting the linear damper 42 within the inner circle of the spring 41. The linear damper 42 is disposed within the spring 41, and one end far from the opening 10b contacts one end of the spring 41 far from the opening 10b through the reduced diameter portion 41b. Thus, the linear damper 42 can be pre-assembled within the spring 41 first, and then the pre-assembled components of the linear damper 42 and the spring 41 are assembled into the housing, which improves the assembly efficiency, is conducive to achieving automated assembly, thereby improving the production efficiency and reducing the labor cost.

[0086] In some embodiments, please refer to Figure 3 and Figure 7 , one end of the linear damper 42 close to the opening 10b contacts the transmission member 30, and one end far from the opening 10b is connected to the housing 10. One end of the spring 41 close to the opening 10b contacts the transmission member 30, and one end far from the opening 10b contacts the linear damper 42.

[0087] In this embodiment, one end of the linear damper 42 close to the opening 10b contacts the transmission member 30, and one end far from the opening 10b is connected to the housing 10. That is to say, the linear damper 42 is directly fixed to the housing 10, thereby improving the reliability and stability of the linear damper 42.

[0088] The spring 41 is sleeved on the outer periphery of the linear damper 42. One end close to the opening 10b contacts the transmission member 30, and one end far from the opening 10b contacts the linear damper 42. For example, it contacts one end of the linear damper 42 far from the opening 10b. That is to say, the spring 41 is clamped between the transmission member 30 and one end of the linear damper 42 far from the opening 10b.

[0089] It should be noted that the manner in which the linear damper 42 is fixed to the housing 10 is not limited herein.

[0090] In some embodiments, please refer to Figure 3 and Figure 7 , the damping device 100 further includes a fixing pin 50. A plug 13 is integrally formed at one end of the linear damper 42 far from the opening 10b. The fixing pin 50 is inserted into the plug 13 and the housing 10 to connect the linear damper 42 to the housing 10.

[0091] By forming corresponding insertion holes on the plug 13 and the housing 10, and inserting the fixing pin 50 into the insertion holes on the plug 13 and the housing 10, the fixing between the linear damper 42 and the housing 10 is achieved.

[0092] Exemplarily, the fixing pin 50 is provided with knurling, thereby improving the reliability of the connection structure between the fixing pin 50 and the plug 13 and the housing 10.

[0093] It should be noted that the specific structure of the housing 10 is not limited herein.

[0094] In some embodiments, please refer to Figure 4 and Figure 8 , the housing 10 includes a body 11 and a cover 12. The body 11 has a receiving cavity 10a and an installation opening 10c communicating with the receiving cavity 10a. The cover 12 has an opening 10b penetrating through the cover 12. The cover 12 is provided at the installation opening 10c, and the opening 10b communicates with the receiving cavity 10a.

[0095] Here, by providing the body 11 and the cover 12 with the opening 10b, the body 11 is provided with the receiving cavity 10a and the installation opening 10c communicating with the receiving cavity 10a. Thus, during assembly, first remove the cover 12 from the body 11, then insert the linear damper 42 and the spring 41 into the receiving cavity 10a of the body 11 through the installation opening 10c, and then insert the transmission member 30 and the rotating member 20 into the receiving cavity 10a, so that the transmission member 30 and the bottom wall 10d of the housing opposite to the opening 10b clamp the linear damper 42 and the spring 41 therebetween. Finally, install the cover 12 at the installation opening 10c, and the rotating shaft 21 of the rotating member 20 extends out through the opening 10b of the cover 12, thus completing the assembly of the damping device 100, improving the assembly efficiency, facilitating automated assembly, and further improving the production efficiency and reducing the labor cost.

[0096] That is to say, by setting the housing 10 to include the body 11 and the cover 12, the cover 12 can be removed to assemble the damping device 100, which is beneficial to improving the assembly efficiency of the damping device 100.

[0097] It should be noted that the connection manner between the body 11 and the cover 12 is not limited herein.

[0098] Exemplarily, the body 11 and the cover 12 can be connected by snap connection, plug connection or fastening connection. In the embodiments of the present application, the body 11 and the cover 12 are snap-connected, which is beneficial to realizing automated assembly.

[0099] In some other embodiments, please refer to Figure 5 , Figure 6 , Figure 9 and Figure 10 , the housing 10 includes a body 11 and a plug 13. The body 11 is provided with a receiving cavity 10a having an opening 10b. One end of the body 11 far from the opening 10b is provided with an installation opening 10c, and the plug 13 is provided at the installation opening 10c.

[0100] Here, openings 10b and mounting ports 10c are respectively formed at opposite ends of the main body 11. Among them, the rotating shaft 21 extends out through the opening 10b for connecting to the door cover 200, and other components of the damping device 100 can be assembled into the accommodation cavity 10a through the mounting port 10c.

[0101] It should be noted that the bottom wall of the plug 13 facing the opening 10b is equivalent to the bottom wall 10d of the housing.

[0102] Here, by providing the main body 11 and the plug 13, the main body 11 is provided with an accommodation cavity 10a and openings 10b and mounting ports 10c at opposite ends of the accommodation cavity 10a. Thus, during assembly, first remove the plug 13 from the main body 11, then insert the rotating member 20 and the transmission member 30 into the accommodation cavity 10a. The rotating shaft 21 of the rotating member 20 extends out through the opening 10b of the cover body 12. Then, insert the linear damper 42 and the spring 41 into the accommodation cavity 10a of the main body 11 through the mounting port 10c. Finally, install the plug 13 at the mounting port 10c so that the transmission member 30 and the bottom wall 10d of the housing clamp the linear damper 42 and the spring 41 between them, thus completing the assembly of the damping device 100.

[0103] That is to say, by setting the housing 10 to include the main body 11 and the plug 13, the damping device 100 can be assembled by removing the plug 13, which is beneficial to improving the assembly efficiency of the damping device 100.

[0104] It should be noted that the connection method between the main body 11 and the plug 13 is not limited here.

[0105] Exemplarily, please refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 8 , the cover body 12 is inserted into the mounting port 10c, and by forming corresponding insertion holes on the main body 11 and the plug 13, the main body 11 and the plug 13 are fixed by inserting the fixing pin 50 into the insertion holes on the main body 11 and the plug 13.

[0106] It should be noted that the plug 13 and the linear damper 42 can be an integrally formed structure. For example, an integrally formed plastic part or an integrally formed metal part, etc. The integrated plug 13 and linear damper 42 can reduce the number of components, reduce the assembly time, and improve the assembly efficiency.

[0107] Of course, the plug 13 and the linear damper 42 can also be a split structure.

[0108] In some embodiments, please refer to Figures 3 to 6A first guide slope 20a is provided on the side of the rotating member 20 facing the transmission member 30, and a second guide slope 30a adapted to the first guide slope 20a is provided on the side of the transmission member 30 facing the rotating member 20, so that the transmission member 30 can rotate and slide relative to the rotating member 20 during the process of opening or closing the door cover 200 to approach or move away from the rotating member 20.

[0109] Here, the specific type and specific number of the first guide slope 20a and the second guide slope 30a are not limited, as long as they can cooperate with each other to enable the transmission member 30 to rotate and slide relative to the rotating member 20 during the opening or closing process of the door cover 200.

[0110] Exemplarily, the rotating member 20 can be provided with a wedge-shaped groove, and the transmission member 30 can be provided with a wedge-shaped protrusion 30b, at least a portion of the groove wall of the wedge-shaped groove is defined as a first guide bevel 20a, and at least a portion of the side wall of the wedge-shaped protrusion 30b is defined as a second guide bevel 30a, and the wedge-shaped protrusion 30b is inserted into the wedge-shaped groove so that the first guide bevel 20a is in contact with the second guide bevel 30a.

[0111] Here, the rotating member 20 is provided with a first guide bevel 20a, and the transmission member 30 is provided with a second guide bevel 30a, so that during the rotation of the rotating member 20, the first guide bevel 20a cooperates with the second guide bevel 30a to drive the transmission member 30 to slide relative to the rotating member 20. During the sliding process, the transmission member 30 squeezes the damping unit 40 so that the damping unit 40 generates a damping force on the transmission member 30.

[0112] In some embodiments, a groove is provided on the wall of the accommodating cavity 10a, and a protrusion 30b is provided on the peripheral side of the transmission member 30. The protrusion 30b cooperates with the groove to enable the transmission member 30 to slide between the first position and the second position and cooperate with the shell 10 to prevent rotation.

[0113] Here, the cavity wall of the accommodating cavity 10a is provided with a groove, which extends, for example, along the axial direction of the damping device 100. This facilitates the transmission member 30 to slide along the extension direction of the groove through the protrusion 30b, thereby enabling the transmission member 30 to slide between the first position and the second position.

[0114] In addition, the groove can also limit the transmission member 30 in the circumferential direction, preventing the transmission member 30 from rotating relative to the housing 10 along with the rotating member 20, thereby hindering the transmission member 30 from sliding between the first position and the second position.

[0115] Furthermore, the cavity wall of the accommodating cavity 10 a is provided with a groove, which will not affect the assembly of other components of the damping device 100 .

[0116] In some embodiments, one of the rotating member 20 and the transmission member 30 can be provided with a connecting shaft, and the other can be provided with a connecting channel. The rotating member 20 and the transmission member 30 are plugged into the connecting channel through the connecting shaft to achieve reliability and stability of the connection and movement between the two.

[0117] Specifically, a connecting shaft is provided at the center of the rotating member 20 , and a connecting channel is provided at the center of the transmission member 30 .

[0118] In some embodiments, see Figures 3 to 7 The damping device 100 also includes a gasket 60, which is sleeved on the rotating shaft 21 of the rotating member 20 and clamped between the rotating member 20 and the housing 10, thereby reducing the friction between the rotating member 20 and the housing 10 and reducing damage to the housing 10 caused by the rotation of the rotating member 20.

[0119] In some embodiments, see Figures 5 to 6 The direction in which the opening 10b enters the accommodating cavity 10a is defined as a first direction. In a cross section perpendicular to the first direction, the cross-sectional shape of the housing 10 is an arch shape composed of arc segments and straight line segments.

[0120] Exemplarily, the first direction is, for example, the axial direction of the housing 10 , that is, the opening 10 b is provided at one end of the housing 10 in the axial direction.

[0121] Specifically, the arc segment is, for example, a semicircle, and the straight line segment is, for example, three straight line segments perpendicularly connected to each other, and the straight line segments at both ends are tangently connected to the two ends of the semicircle respectively.

[0122] Here, by configuring the cross-section of the housing 10 to be an arched shape composed of arc segments and straight segments, the housing 10 can contact the door cover 200 via the straight segments, thereby improving the reliability and stability of the connection between the housing 10 and the door cover 200. In addition, by configuring the side of the housing 10 facing away from the straight segments as an arc segment, the space occupied by the housing 10 can be minimized while maintaining the same dimensions of the accommodating cavity 10a, thereby improving the structural compactness of the damping device 100.
