[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] The washing machine of the present invention includes a washing machine frame 1, a tub body 2 positioned within the washing machine frame 1, and a tub cover 6 mounted on the tub body 2. The washing machine's flexible shock-absorbing assembly includes a support plate 3, a shock-absorbing device 4, and a support frame 5. The support frame 5 includes a front support frame 50 and a rear support frame 51 connected to the washing machine frame 1 and arranged in a front-to-back arrangement. As another embodiment of the present invention, multiple support frames 5 can also be arranged on the washing machine frame 1 in a left-right arrangement.

[0021] The shock-absorbing device 4 includes shock-absorbing rubber blocks 40 and shock-absorbing sheet metal 41 mounted on the shock-absorbing rubber blocks. The number of shock-absorbing rubber blocks 40 corresponds to the number of shock-absorbing sheet metal 41. The shock-absorbing rubber blocks 40 include two groups mounted on the front support frame 50 and two groups mounted on the rear support frame 51. Each group of shock-absorbing rubber blocks 40 contains a plurality of shock-absorbing rubber blocks. In one embodiment of the present invention, each group of shock-absorbing rubber blocks 40 contains two shock-absorbing rubber blocks. The two groups of shock-absorbing rubber blocks 40 mounted on the front support frame 50 are the left front shock-absorbing rubber block group and the right front shock-absorbing rubber block group, and the two groups of shock-absorbing rubber blocks 40 mounted on the rear support frame 51 are the left rear shock-absorbing rubber block group and the right rear shock-absorbing rubber block group. The shock-absorbing sheet metal 41 includes a left front shock-absorbing sheet metal group installed on the left front shock-absorbing rubber block group, a right front shock-absorbing sheet metal group installed on the right front shock-absorbing rubber block group, a left rear shock-absorbing sheet metal group installed on the left rear shock-absorbing rubber block group, and a right rear shock-absorbing sheet metal group installed on the right rear shock-absorbing rubber block group.

[0022] The support plate 3 includes a left front support plate 30 installed on the left front shock-absorbing sheet metal group, a right front support plate 31 installed on the right front shock-absorbing sheet metal group, a left rear support plate 32 installed on the left rear shock-absorbing sheet metal group, and a right rear support plate 33 installed on the right rear shock-absorbing sheet metal group.

[0023] The barrel body 2 includes a left barrel body 20 and a right barrel body 21 spaced apart from each other, and the barrel cover 6 includes a left barrel cover 60 installed together with the left barrel body 20 and a right barrel cover 61 installed together with the right barrel body 21.

[0024] The left front support plate 30 and the left rear support plate 32 are respectively installed on the lower surfaces of the left barrel cover 60 and the left barrel body 20 by screws, and the right front support plate 31 and the right rear support plate 33 are respectively installed on the lower surfaces of the right barrel cover 61 and the right barrel body 21 by screws.

[0025] In the flexible vibration-damping assembly of the washing machine disclosed herein, because both ends of the support plate are connected to the tub lid and the vibration-damping device, or to the tub body and the vibration-damping device, when vibration energy is transmitted to the support plate, the central region undergoes significant elastic deformation. This design utilizes the support plate's inherent elastic properties to actively absorb and dissipate some of the vibration energy while transmitting vibration. Therefore, the support plate not only transmits vibration, but its elastic deformation itself also constitutes a crucial factor in resisting vibration of the tub body and lid, thereby improving the stability of the entire machine.

[0026] The shock-absorbing sheet metal 41 is machined from high-density metal and screwed to the shock-absorbing rubber block 40. Its core function is to significantly increase the overall mass of the shock-absorbing system. As the core shock-absorbing component, the shock-absorbing rubber block 40 is made of an elastic material with excellent damping properties. Bolted to the support plate 3, it performs the dual tasks of supporting static loads and converting dynamic energy. The elastic properties of the shock-absorbing rubber block 40 provide the necessary support stiffness, while its high internal damping effectively converts and dissipates the incoming mechanical vibration energy into heat. Together, the shock-absorbing sheet metal 41 and the shock-absorbing rubber block 40 form a complete shock-absorbing device.

[0027] The support plate 3 is a long sheet metal part formed by high-strength metal stamping. Its two ends are rigidly fixed to the washing machine frame 1 by screws, forming a beam structure with fixed supports at both ends and a suspended middle part. This design not only fulfills the basic support function (providing a mounting base for the shock-absorbing rubber block 40 and the shock-absorbing sheet metal 41 and transmitting loads), but also has the value of active shock absorption. After the shock-absorbing rubber block 40 dissipates the main vibration energy, when the residual high-frequency vibration is transmitted to the support plate 3, the suspended section in the middle achieves three-level attenuation through controllable elastic bending deformation: ① converting the residual mechanical energy into stress dissipation in the plate, ② using deformation displacement to buffer the instantaneous impact force peak, and ③ decoupling from the main shock absorption system through its own natural frequency to avoid energy superposition.

[0028] The flexible shock-absorbing assembly of the washing machine of the present invention can achieve high-efficiency suppression of multi-dimensional vibration and space utilization without requiring a suspension spring assembly.

[0029] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
