As shown in fig. 1, the embodiment of the present invention provides a vibration damping assembly 1, which can be used for vibration isolation of a device (such as a motor or a water pump) that can generate vibration during operation, so as to reduce noise generated by vibration, and the device can be a washing machine, a washing and drying machine, a dishwasher, or the like. In the present embodiment, the vibration damping module 1 is used for vibration damping of a drain pump in a laundry machine, but the application range of the vibration damping module 1 is not limited.

As shown in fig. 1 and 2, the damping assembly 1 includes a damping member 11, a fastening member 12, and a limiting member 13; the damping member 11 is provided between the supported member and the mounting base. In the embodiment of the present invention, the vibration damping assembly 1 is mainly used for vibration isolation of a drainage pump on a clothes treatment device, and thus, the supported member is the drainage pump, and the mounting base is the mounting frame 21 or the base for fixedly supporting the drainage pump. The vibration damping member 11 is made of a material that can be elastically deformed, such as rubber or silicone, so that vibration generated from the drain pump can be absorbed during the elastic deformation of the vibration damping member 11. The vibration damping member 11 is provided with a connecting structure 112 connected with the supported member, and the connection of the drain pump and the vibration damping assembly 1 is realized through the connecting structure 112. The fastening member 12 is used to fix the damping member 11 to the mounting base, and one end of the limiting member 13 is connected to the damping member 11, and the other end is connected to the fastening member 12. The limiting member 13 is preferably made of a rigid material, and is connected to the damping member 11, so that the supporting strength of the damping member 11 can be enhanced, and the supported member can be reliably supported. With this arrangement, the damping member 11 is disposed between the supported member and the mounting base and fixed by the fastening member 12, so that the damping member 11 can be reliably fixed to the mounting base. Accordingly, vibration isolation is achieved by elastic deformation of the vibration damping member 11, and transmission of vibration generated by the supported member to the mounting base is reduced, thereby reducing noise generated by the vibration.

In practical arrangement, one end of the damping member 11 is pressed against the mounting base, the fastening member 12 is connected to the limiting member 13, and the limiting member 13 is connected to the damping member 11. Thus, the fastener 12 can continuously compress the damper 11 while being connected to the stopper 13. When the deformation amount of the damping piece 11 is too small, the supported piece can be installed unstably; when the amount of deformation of the damping member 11 is too large, the elastic deformation effect of the damping member 11 is reduced, and the vibration cannot be absorbed effectively, so that the damping performance cannot meet the use requirement. Therefore, in the embodiment of the present invention, as shown in fig. 1 and 2, in order to reliably realize the vibration damping effect of the vibration damper 11, a limiting gap 14 for limiting the deformation amount of the vibration damper 11 is formed between the limiting member 13 and the mounting base. That is, the limit clearance 14 is used to limit the amount of deformation of the damper 11 that needs to occur when the damper is fixedly connected by the fastener 12. Specifically, the height of the limiting gap 14 satisfies that the deformation amount of the vibration damping piece 11 can satisfy stable assembly during fixed installation, and the reduction of the vibration damping effect caused by excessive deformation of the vibration damping piece 11 can be avoided. During specific connection, under the connection fixing action of the fastening piece 12, the limit gap 14 is gradually reduced, and meanwhile, the damping piece 11 is compressed, so that the connection stability between the damping piece and a supported piece can be continuously improved. When one end of the limiting member 13 abuts against the mounting base, the damping member 11 is fixedly mounted, and the height of the limiting gap 14 is reduced to be approximately zero. Due to the limitation of the limiting piece 13, the damping piece 11 can be ensured not to be compressed continuously, and the deformation quantity of the damping piece 11 in the state can not reduce the damping performance, so that the reliable fixation of the supported piece can be met, a good damping state can be achieved, and the design ingeniousness is good.

Specifically, the connection between the limiting member 13 and the vibration damping member 11 may be formed as an integral structure by embedding the limiting member 13 inside the vibration damping member 11, and at the same time, the effect point of the limiting member 13 capable of applying a pressing force to the vibration damping member 11 is higher than the position of the connection structure 112 arranged on the vibration damping member 11 during fastening, so as to ensure that the connection structure 112 can be pressed above the connection structure 112 during fastening, so that the connection structure 112 is deformed, and the supported member can be clamped and fixed. The limiting part 13 and the damping part 11 are both arranged at one end facing the mounting base such that the limiting part 13 is recessed in the damping part 11, so that the damping part 11 can directly press against the mounting base, and the limiting part 13 is not in contact with the mounting base, so that a certain spacing distance exists, which is the height of the limiting gap 14.

As shown in fig. 1, the limiting member 13 includes a limiting body 131 and a connecting plate 132. A connecting hole 133 for inserting and connecting the fastener 12 is formed inside the limiting body 131; the connecting plate 132 is used for connecting with the damping member 11, and the connecting plate 132 is fixedly connected to one end of the limiting body 131. And a spacing gap 14 is formed between the other end of the spacing body 131 and the mounting base. Specifically, in the embodiment of the present invention, the fastening member 12 is preferably configured as a screw, and thus, the connecting hole 133 is a threaded hole. Meanwhile, it is preferable to set the horizontal sectional area of the connection plate 132 to be larger than the horizontal sectional area of the limiting body 131 and smaller than the horizontal sectional area of the damping member 11, so that not only the connection area with the damping member 11 can be increased, but also a large action area for compressing the damping member 11 downward can be generated at the time of fastening, to improve the reliability of fastening.

As shown in fig. 1 and 2, in the embodiment of the present invention, the damping member 11 includes a damping body 111, and the connecting plate 132 is used to connect with the damping body 111. The damping body 111 has a mounting hole 113 formed therein for inserting the limiting body 131, and the depth of the mounting hole 113 is greater than the length of the limiting body 131 by a value equal to the height of the limiting gap 14. In a practical setting, it is preferable to set the value of greater than 1 mm. The connecting structure 112 is disposed on the outer side wall of the vibration damping body 111, and the connecting structure 112 is preferably disposed in the middle of the vibration damping body 111 in the length direction, and the distances from the upper and lower ends of the vibration damping body 111 are substantially equal, and the length of the distance is not less than 4 mm. Through the arrangement, the damping member 11 and the limiting member 13 are two independent parts, when the damping member is installed, the limiting body 131 is inserted from one end of the damping body 111, the limiting body 131 is located in the installation hole 113, the connecting plate 132 is pressed against the end of the damping body 111, and then the connecting plate 132 is connected with the limiting body 131 through the fastener 12, so that the connecting plate 132 generates pressing force on the damping body 111 to fix the damping body 111 on the installation base. The damping piece 11 and the limiting piece 13 are arranged into two independent parts, so that the production and the manufacture are convenient, and the installation is also convenient.

In the specific arrangement, the fixing groove 114 and the connecting plate 132 are preferably set to be multi-variable shapes with the same shape, so that after the connecting plate 132 is arranged in the fixing groove 114, not only can the mounting position of the connecting plate 132 be limited, but also the connecting plate 132 can be prevented from rotating in the fixing groove 114 when the fastener 12 is screwed down, and the fastening operation is facilitated.

In a practical arrangement, it is preferable to set the depth of the fixing groove 114 to be greater than the thickness of the connecting plate 132. Thus, when the connection plate 132 is mounted in the fixing groove 114, the top end of the connection plate 132 does not protrude above the fixing groove 114. Thus, after the connection with the supported member is completed, the connecting plate 132 will not directly contact with the supported member, so as to avoid the vibration generated by the supported member from being directly transmitted to the mounting base by the limiting member 13, and ensure the reliability of the vibration damping effect.

As shown in fig. 1, in the embodiment of the present invention, the connection structure 112 is preferably configured as a mounting groove, and the mounting groove is disposed around the outer sidewall of the damping body 111, and the opening width of the mounting groove is slightly smaller than the thickness of the supported member for being inserted into the mounting groove.
