However, in the case of full-load dehydration of the washing machine, the compression amount of the hanger springs is relatively large. During the dehydration movement, due to uneven placement of the load and different forces on the four hangers, the tub is prone to large inclination, large vibration, and poor shock absorption effect.

[0003] Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

[0031] The following will illustrate the embodiments of the present utility model with reference to the drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be understood that the preferred embodiments are only for explaining the present utility model, rather than for limiting the protection scope of the present utility model.

[0032] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present utility model. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0033] The present utility model provides a shock-absorbing structure, as Figure 1 shown. The shock-absorbing structure includes a suspension rod 1 and a flexible shock-absorbing body 2. Specifically, there is an upper fixed position on the washing machine body, and there is a lower fixed position at the bottom of the outer tub 100 of the washing machine. The lower fixed position is lower than the upper fixed position. One end of the suspension rod 1 is used for assembling and fixing with the upper fixed position, and the other end is used for assembling and fixing with the lower fixed position. The flexible shock-absorbing body 2 is sleeved on the suspension rod 1.

[0034] In this application, while adding the suspension rod 1 between the outer tub 100 and the body, the flexible shock-absorbing body 2 is provided on the suspension rod 1. The flexible shock-absorbing body 2 can play a role in shock absorption. When the washing machine is working, especially during high-speed dehydration, the vibration generated by the outer tub 100 can be partially absorbed and buffered by the flexible shock-absorbing body 2. And the flexible shock-absorbing body 2 can reduce the direct vibration transmission between the outer tub 100 and the body, thereby reducing the overall vibration feeling of the washing machine.

[0035] It should be noted that the flexible shock-absorbing body 2 has elasticity and can be made of rubber or a material with similar properties to rubber. Due to the elastic performance of the flexible shock-absorbing body 2 itself, it can buffer vibration, and the noise generated when the washing machine is working will be reduced, and the operation will be more stable and quiet. The flexible shock-absorbing body 2 can also adjust different elastic coefficients (rigidities) through different densities, thereby adjusting the shock-absorbing effect. A softer flexible shock-absorbing body 2 can absorb more vibration, but may also cause a larger displacement. While a harder flexible shock-absorbing body 2 can limit the displacement, but the shock-absorbing effect may be relatively poor.

[0036] Meanwhile, compared with the spring hanger rod 1 in the prior art, in the present application, the flexible shock absorber 2 is made of rubber material. Rubber material has higher rigidity and smaller compression amount compared with the spring. Under the action of the same external force, the deformation amount of rubber is relatively small, which helps to maintain the stability of the outer tub 100 and avoid excessive inclination during high-speed rotation. Rubber has higher internal damping and can effectively absorb and dissipate vibration energy. This high-damping characteristic enables the flexible shock absorber 2 to better suppress the vibration generated by the outer tub 100 during the dehydration process, thereby improving the overall stability and operation smoothness of the washing machine. The design of the flexible shock absorber 2 is usually optimized for the working load of the washing machine to provide better support and control. Due to the small compression amount and high stability of rubber, it can better control the position of the outer tub 100, enabling the outer tub 100 to remain balanced during dehydration and reducing the occurrence of inclination and irregular vibration. It can be seen that due to the large compression amount and low damping of the spring, it is easy to cause the outer tub 100 to incline and have poor vibration effect during high-speed dehydration. In contrast, the flexible shock absorber 2 has a small compression amount and high damping, and can better maintain the stability of the outer tub 100. Since an elastomer with a small deformation amount up and down is used, the up and down movement amount of the outer tub 100 during no-load and full-load is small, making the distance between the protective frame under the outer tub 100 and the ground greater than the minimum safety height when full-loaded. The extra part can be used to increase the height of the outer tub 100 and the dehydration tub, thereby increasing the washing and dehydration capacity of the whole machine, and thus realizing a large capacity in a small volume; or the extra part can be used to reduce the height of the whole machine, thereby reducing the material usage and achieving the purpose of reducing the material cost of the whole machine.

[0037] It should be noted that in order to maintain the stability of the outer tub 100, there are 4 hanger rods 1, which are evenly distributed along the periphery of the outer tub 100. Thus, under the vibration absorption effect of the flexible shock absorber 2, the sinking distance of the outer tub 100 is reduced, the difference in deformation of the four shock absorption structures is reduced, and the vibration is reduced.

[0038] As Figure 2 shown, the flexible shock absorber 2 includes a flexible support unit 21 and two anti-retreat pins 22. The flexible support unit 21 is sleeved on the hanger rod 1. The two anti-retreat pins 22 are arranged along the axial direction of the hanger rod 1 and are respectively close to both ends of the flexible support unit 21. Both of the two anti-retreat pins 22 vertically penetrate the hanger rod 1 and cooperate with the flexible support unit 21 to define the minimum elastic length of the flexible support unit 21.

[0039] Specifically, the flexible support unit 21 is made of rubber material; the anti-retreat pin 22 penetrates through the suspension rod 1 and is perpendicular to the suspension rod 1; the two anti-retreat pins 22 are respectively close to both ends of the flexible support unit 21 and cooperate with the flexible support unit 21, so that when the flexible support unit 21 retracts under the action of vibration, it can be limited by the anti-retreat pins 22. Then, the cooperation of the two anti-retreat pins 22 can define the minimum elastic length of the flexible support unit 21.

[0040] In an embodiment of the present application, as Figure 2 and Figure 3 shown, the flexible support unit 21 includes a flexible connection member 212 and two shock-absorbing support members 211; the two shock-absorbing support members 211 are arranged along the axial direction of the suspension rod 1 and correspond to the anti-retreat pins 22 one by one; the flexible connection member 212 is located between the two shock-absorbing support members 211 and is respectively assembled with the two shock-absorbing support members 211.

[0041] Specifically, the two anti-retreat pins 22 are located between the two shock-absorbing support members 211; the shock-absorbing support members 211 are sleeved on the suspension rod 1 and can slide along the suspension rod 1; the anti-retreat pin 22 vertically penetrates through the suspension rod 1, and both ends of the anti-retreat pin 22 extend outside the suspension rod 1. The part of the anti-retreat pin 22 extending outside the suspension rod 1 is located on the sliding path of the shock-absorbing support member 211, so that the minimum distance between the two shock-absorbing support members 211 (i.e., the minimum elastic length of the flexible support unit 21) is the distance between the two anti-retreat pins 22.

[0042] Installation holes are provided on the suspension rod 1 corresponding to the anti-retreat pins 22, and the anti-retreat pins 22 pass through the installation holes and are in interference fit with the installation holes to reduce the displacement of the anti-retreat pins 22 relative to the suspension rod 1 under the action of vibration.

[0043] As Figure 3 shown, a receiving groove 6 is provided on one side of the shock-absorbing support member 211 corresponding to the anti-retreat pin 22, and the part of the anti-retreat pin 22 extending outside the suspension rod 1 is located in the receiving groove 6. The cooperation between the receiving groove 6 and the anti-retreat pin 22 can increase the contact area between the anti-retreat pin 22 and the shock-absorbing support member 211, improve the assembly stability between the anti-retreat pin 22 and the shock-absorbing support member 211, reduce the displacement amount of the shock-absorbing support member 211 relative to the anti-retreat pin 22, and thus improve the shock-absorbing effect of the flexible shock-absorbing body 2.

[0044] In an embodiment of this embodiment, the flexible connection member 212 includes a sleeve, and the axial two ends of the sleeve are respectively connected to the two shock-absorbing support members 211; the two anti-retreat pins 22 are both located inside the sleeve.

[0045] In this embodiment, the two shock-absorbing supports 211 are positioned and connected by the sleeve. Then, the vibration between the two shock-absorbing supports 211 can be transmitted through the sleeve. The two shock-absorbing supports 211 can provide double buffering to further absorb and disperse the vibration generated by the outer tub 100; the connection through the sleeve can enable the two shock-absorbing supports 211 to work in coordination to provide more effective vibration mitigation.

[0046] The rubber material itself has good shock-absorbing characteristics, and the shock-absorbing support 211 is a rubber shock-absorbing support 211. The sleeve can play a role in isolating and dispersing vibration between the two shock-absorbing supports 211, reducing the vibration transmitted to the washing machine body through the suspension rod 1, thereby reducing the overall vibration and noise of the washing machine. Moreover, the sleeve can ensure that the two shock-absorbing supports 211 maintain the correct relative position on the suspension rod 1, preventing the shock-absorbing supports 211 from being displaced or deformed due to vibration, which can improve the stability of the entire shock-absorbing system and ensure the consistency of the shock-absorbing effect.

[0047] At the same time, through the connection of the sleeve, the relative position and cooperation of the two shock-absorbing supports 211 can be more flexible. Designers can adjust the length of the sleeve or the material and hardness of the shock-absorbing support 211 according to different shock-absorbing requirements to optimize the shock-absorbing effect; the two shock-absorbing supports 211 connected by the sleeve can absorb vibration in sequence to provide a progressive shock-absorbing effect. This design can enable the washing machine to have good shock-absorbing performance in different working states (such as washing and dehydration), and avoid sudden severe vibration when the dehydration tub rotates at high speed.

[0048] In one embodiment of this example, the sleeve and the two shock-absorbing supports 211 are of an integrally formed structure.

[0049] In another embodiment of this example, as Figure 3 shown, the flexible connecting member 212 is made of a flexible material such as rubber with equivalent characteristics; the flexible connecting member 212 includes a flexible shock-absorbing ring; the flexible shock-absorbing ring is arranged parallel to the suspension rod 1 and is respectively sleeved on the two shock-absorbing supports 211.

[0050] Compared with the sleeve, the flexible shock-absorbing ring has a simpler structure, is easy to install and disassemble, reduces the number of components, can simplify the production process, and thus reduces the manufacturing cost; the flexible shock-absorbing ring has good elasticity and stretchability, and can more flexibly adapt to the deformation and displacement of the shock-absorbing support member 211 during use. This flexibility can provide a smoother shock-absorbing effect when the washing machine is working; the flexible shock-absorbing ring can also automatically adjust its tension and shape when the shock-absorbing support member 211 is stressed, adapt to different vibration intensities and directions, and provide an adaptive shock-absorbing effect.

[0051] The flexible shock-absorbing ring can be one or more; for example, the flexible shock-absorbing ring is two, and the two flexible shock-absorbing rings are symmetrically arranged on both sides of the suspension rod 1. The two flexible shock-absorbing rings assemble and position between the two shock-absorbing support members 211, which is sufficient to ensure the assembly stability between the two shock-absorbing support members 211 while reducing the number of components, simplifying the production process, and reducing the production cost, and ensure that the sliding of the shock-absorbing support member 211 along the suspension rod 1 under the action of vibration is parallel sliding, thereby reducing the probability of the shock-absorbing support member 211 being skewed.

[0052] In an embodiment of the present application, as Figure 4 shown, grooves 3 are provided on the opposite sides of the two shock-absorbing support members 211, and the flexible shock-absorbing ring is partially located in the grooves 3.

[0053] The grooves 3 are used to accommodate the flexible shock-absorbing ring. After the two ends of the flexible shock-absorbing ring are respectively sleeved on the two shock-absorbing support members 211, they can be accommodated in the corresponding grooves 3. This not only increases the contact area between the flexible shock-absorbing ring and the shock-absorbing support member 211 through the grooves 3, but also can limit the flexible shock-absorbing ring through the grooves 3, thereby improving the assembly stability between the flexible shock-absorbing ring and the shock-absorbing support member 211.

[0054] The grooves 3 are arc-shaped grooves 3. There are two grooves 3 provided on the shock-absorbing support member 211. The two grooves 3 correspond to the two flexible shock-absorbing rings one by one, and the two grooves 3 are symmetrically arranged along the central axis of the suspension rod 1.

[0055] The flexible support unit 21 further includes a limiting member 4. The limiting member 4 is provided on the shock-absorbing support member 211 near the upper fixed position; a part of the limiting member 4 extends above the opening of the groove 3 to limit the flexible shock-absorbing ring.

[0056] Specifically, as Figure 4As shown, two limiting members 4 are provided on the shock-absorbing support member 211. The two limiting members 4 correspond to the two grooves 3 one by one, and the two limiting members 4 are arranged at intervals through the suspension rod 1. There is a gap between the limiting member 4 and the suspension rod 1, and the gap is used for the flexible shock-absorbing ring to pass through, so as to facilitate sleeving the flexible shock-absorbing ring on the shock-absorbing support member 211 and installing it into the corresponding groove 3.

[0057] The limiting member 4 is an L-shaped limiting member 4, and the limiting member 4 and the suspension rod 1 are distributed on both sides of the groove 3. One end of the limiting member 4 is connected to the shock-absorbing support member 211, and the other end is bent towards the groove 3 and extends above the opening of the groove 3, so as to limit the flexible shock-absorbing ring and prevent the flexible shock-absorbing ring from detaching from the shock-absorbing support member 211 when elastic deformation occurs along the axial direction of the suspension rod 1 under vibration.

[0058] In an embodiment of the present application, the distance between the flexible shock-absorbing body 2 and the lower fixed position is less than the distance between the flexible shock-absorbing body 2 and the upper fixed position.

[0059] Since the center of gravity of the washing machine is lower, in this embodiment, the flexible shock-absorbing body 2 is arranged lower, and the distance between the flexible shock-absorbing body 2 and the lower fixed position is less than the distance between the flexible shock-absorbing body 2 and the upper fixed position, that is, the flexible shock-absorbing body 2 is closer to the lower fixed position, thereby improving the shock-absorbing effect.

[0060] To facilitate the installation of the shock-absorbing structure, a mounting seat 200 is provided at the lower fixed position. In one implementation manner of this embodiment, the flexible shock-absorbing body 2 is located outside the mounting seat 200, and the manufacturing difficulty is relatively low, so the production cost can be reduced, the installation and later maintenance are more convenient, and the complexity of disassembly and assembly is reduced.

[0061] Based on this implementation manner, as Figure 2 and Figure 3 shown, the shock-absorbing structure further includes a base 5. The shock-absorbing support member 211 close to the mounting seat 200 among the two shock-absorbing support members 211 is connected to the base 5; a part of the base 5 is assembled in the mounting seat 200, so as to realize the assembly and positioning between the flexible shock-absorbing body 2 and the mounting seat 200 through the cooperation of the base 5 and the mounting seat 200.

[0062] Specifically, the base 5 includes a connecting member 51, a limiting cover 52 and a support plate 53; the connecting member 51 is sleeved on the suspension rod 1 and arranged coaxially with the suspension rod 1; one end of the connecting member 51 is integrally connected with the corresponding shock-absorbing support member 211, and the other end is integrally connected with the limiting cover 52; the limiting cover 52 is an arc-shaped limiting cover, and is arched upward along the axial direction of the suspension rod 1, and the support plate 53 is located on the side of the limiting cover 52 away from the connecting member 51; the outer circumferential surface of the support plate 53 is connected to the limiting cover 52. A part of the connecting member 51 is located outside the mounting seat 200, and the limiting cover 52 and the support plate 53 are both located inside the mounting seat 200.

[0063] The mounting seat 200 is provided with an arc-shaped assembly surface, and the arc-shaped assembly surface fits with the limit cover 52, thereby increasing the contact area between the mounting seat 200 and the base 5, helping to protect the shock absorbing system, evenly dispersing the force borne by the shock absorbing support 211, and avoiding component fatigue or damage caused by stress concentration.

[0064] In another implementation of this embodiment, the flexible shock absorbing body 2 is located in the mounting seat 200, and the mounting seat 200 can play a better positioning and guiding role; in this way, the shock absorbing structure can respond to the vibration of the outer drum more accurately, and effectively reduce the vibration and noise when the washing machine is working. At the same time, installing the flexible shock absorbing body 2 in the mounting seat 200 can reduce the occupation of the external space, making the internal structure of the washing machine more compact, and helping to design a more miniaturized washing machine. The upper fixed position can also be provided with an upper mounting seat, and the upper mounting seat is assembled and positioned with the suspension rod 1; the upper mounting seat and the mounting seat 200 can both adopt spherical seats.

[0065] The present application also provides a washing machine, comprising the shock absorbing structure as described in any one of the above items.

[0066] In summary, the present application provides a shock-absorbing structure and a washing machine, which includes: a suspension rod; an upper fixing position is provided on the cabinet of the washing machine, and a lower fixing position is provided at the bottom of the outer tub of the washing machine, and the lower fixing position is lower than the upper fixing position; one end of the suspension rod is used for assembling and fixing with the upper fixing position, and the other end is used for assembling and fixing with the lower fixing position; a flexible shock-absorbing body is sleeved on the suspension rod. In the present application, while adding the suspension rod between the outer tub and the cabinet, the flexible shock-absorbing body is provided on the suspension rod, and the flexible shock-absorbing body can play a shock-absorbing role; when the washing machine is working, especially when the dewatering tub is dehydrating at a high speed, the vibration generated by the outer tub can be partially absorbed and buffered by the flexible shock-absorbing body; and the flexible shock-absorbing body can reduce the direct vibration transmission between the outer tub and the cabinet, thereby reducing the overall vibration feeling of the washing machine. At the same time, in the present application, the flexible shock-absorbing body is made of rubber material, and the rubber material has higher rigidity and smaller compression amount compared with the spring. Under the action of the same external force, the deformation amount of the rubber is relatively small, which helps to maintain the stability of the outer tub and avoid excessive inclination when the dewatering tub rotates at a high speed; the rubber has higher internal damping and can effectively absorb and dissipate vibration energy, and this high damping characteristic enables the flexible shock-absorbing body to better suppress the vibration generated by the outer tub during dehydration, thereby improving the overall stability and running smoothness of the washing machine; the design of the flexible shock-absorbing body is usually optimized for the working load of the washing machine to provide better support and control. Due to the small compression amount and high stability of the rubber, it can better control the position of the outer tub, so that the outer tub remains balanced during dehydration and reduces the occurrence of inclination and irregular vibration.
