Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.

The invention provides a suspender, which comprises a rod body 1, a lower suspension ball 4 arranged on the rod body 1 and a damping structure, wherein the damping structure is arranged on the rod body 1, an accommodating cavity is formed inside the damping structure, a non-Newtonian fluid 5 is arranged in the accommodating cavity, and when the lower suspension ball 4 moves downwards, the non-Newtonian fluid 5 can be extruded to generate a damping effect. Referring to fig. 1 to 3, the stability of the washing machine is increased by adding one or two damping structures to the conventional suspension rod, and the damping structure uses non-newtonian fluid, and utilizes the shear thickening characteristic of the non-newtonian fluid to further improve the damping effect of the suspension rod, and the damping structure and the damping spring 2 of the suspension rod act simultaneously, so that the suspension rod has a stronger damping effect.

The non-Newtonian fluid is specifically described as follows: colloidal particles of non-newtonian fluids tend to be densely packed, with water present as a dispersion medium in the interstices of the densely arranged particles. When the sudden external force is transmitted to the non-Newtonian fluid, the particles in the dense arrangement are suddenly disturbed to form a porous loose arrangement structure. At the moment, because the gaps in loose arrangement cannot be filled with water among the particles, the sliding effect of the water layer is lost among the particles, so that the viscosity is greatly increased, the particles have viscoelasticity, the energy caused by collision can be absorbed to the maximum extent, the buffering effect is achieved, and the buffering effect is more obvious under the condition that the sudden change external force is larger.

Regarding the position of the damping structure, the damping structure is arranged between the damping spring 2 of the boom and the lower suspension ball 4 and/or on the side of the damping spring 2 remote from the lower suspension ball 4. Referring to fig. 2, a damping structure is arranged on one side of the damping spring 2 far away from the lower suspension ball 4; referring to fig. 3, a shock absorbing structure is arranged between the shock absorbing spring 2 and the lower suspension ball 4; shock absorption structures can also be arranged between the shock absorption spring 2 and the lower suspension ball 4 and on one side of the shock absorption spring 2 far away from the lower suspension ball 4.

Specifically, the connecting plate 8 is provided with an orifice 801, and when the cavity housing 6 moves downwards, the non-Newtonian fluid 5 above the connecting plate 8 can flow to the lower part of the connecting plate 8 through the orifice 801; or/and the circumferential direction of the connecting plate 8 has a clearance with the inner wall of the cavity shell 6.

Referring to fig. 2, it is shown that the connecting plate 8 is located at the bottom end of the rod body 1, the cavity housing 6 is connected with the lower end of the damping spring 2, and the cavity housing 6 is in sealing fit with the rod body 1. When the jib receives external force, can feed back the lower part very first time and hang on ball 4, lower part hangs ball 4 and receives external force, can compress damping spring 2, damping spring 2 can exert a pressure to cavity shell 6 because deformation, cavity shell 6 can take place decurrent removal for the body of rod 1, connecting plate 8 is fixed relatively with the body of rod 1, then cavity shell 6 can take place relative motion with connecting plate 8, non-Newton's fluid 5 in the cavity can receive the compression and takes place to flow through orifice 801, produce the damping effect, because the characteristic of non-Newton's fluid shear thickening, non-Newton's fluid is under the big circumstances of sudden change external force, the cushioning effect is then more obvious. Meanwhile, the resetting device 7 is compressed and can play a certain buffering role. When the external force is reduced, the reset spring 5 can expand the cavity shell 6 and the connecting plate 8, so that the two can continuously have a relative movement space.

In addition, it should be noted that, for the damping structure illustrated in fig. 2, the damping structure may also be disposed between the damping spring 2 and the lower suspension ball 4, at this time, the rod body 1 penetrates through the cavity housing 6, when the suspension rod receives an external force, the external force is fed back to the lower suspension ball 4 at the first time, the lower suspension ball 4 receives the external force and drives the cavity housing 6 to move downward, the connecting plate 8 and the rod body 1 are relatively fixed, the cavity housing 6 and the connecting plate 8 generate relative movement, and the non-newtonian fluid 5 in the cavity is compressed and flows through the orifice 801 to generate a damping effect; the cavity housing 6 moves downwards to compress the damping spring 2 (the bottom of the damping spring 2 is provided with a fixed limiting plate).
