FIG. 1 , an embodiment of this application provides a washing machine. The washing machine includes a suspension spring mounting structure according to the embodiment of this application. The suspension spring mounting structure includes a suspension spring gasket 1 and asuspension spring bracket 2, which will be described in detail below. The washing machine further includes asuspension spring 3 and atub assembly 4, where two ends of thesuspension spring 3 are connected to the suspension spring mounting structure and thetub assembly 4 respectively. - As shown in
FIG. 2 to FIG. 10 , an embodiment of this application further provides a suspension spring mounting structure. The suspension spring mounting structure includes a suspension spring gasket 1 and asuspension spring bracket 2. The suspension spring gasket 1 includes an abuttingportion 11 and ananti-tilting portion 12. Thesuspension spring bracket 2 is configured to mount the suspension spring gasket 1, and includes amating portion 21 and a buttingportion 22. One of the abuttingportion 11 and themating portion 12 is an arc-shaped protrusion, and the other one is an arc-shaped recess. When the suspension spring gasket 1 is mounted on thesuspension spring bracket 2, the arc-shaped protrusion abuts against the arc-shaped recess, and theanti-tilting portion 12 abuts against the buttingportion 22 to act together to fix the suspension spring gasket 1 to thesuspension spring bracket 2. - In a using process, when the
suspension spring 3 is hooked on the suspension spring gasket 1, the suspension spring gasket 1 transmits the force ofsuspension spring 3 to thesuspension spring bracket 2. Because the arc-shaped protrusion and the matching arc-shaped recess are provided, the mounting abutting area between the suspension spring gasket 1 and thesuspension spring bracket 2 can be increased, and the force may be better dispersed to avoid stress concentration. Theanti-tilting portion 12 may further prevent a relative tilt between the arc-shaped protrusion and the arc-shaped recess, and may better fix the suspension spring gasket 1 on thesuspension spring bracket 2 to prevent the suspension spring gasket 1 from falling off from thesuspension spring bracket 2 in a using process. - In an optional solution of this embodiment, the suspension spring gasket 1 further includes a
hook portion 13 for hooking thesuspension spring 3, and thehook portion 13 includes an arc-shaped protruding surface. - Specifically, as shown in
FIG. 4 andFIG. 9 , thehook portion 13 is provided with an arc-shaped protruding shape. When thesuspension spring 3 is hooked on the arc-shaped protruding surface, an abutting contact area between thesuspension spring 3 and the suspension spring gasket 1 may be increased, so that the force of thesuspension spring 3 acting on the suspension spring gasket 1 may be more stable and more evenly distributed on the suspension spring gasket 1, to prevent stress on the suspension spring gasket 1 from being excessively concentrated when thesuspension spring 3 is hooked on the arc-shaped protruding surface, and also improve the mounting stability of the suspension spring gasket 1 to thesuspension spring 3. - In an optional solution of this embodiment, the
hook portion 13 includes afirst segment 131, anarc segment 132 and asecond segment 133 sequentially connected, and two ends of theanti-tilting portion 12 are connected to thefirst segment 131 and thesecond segment 133 respectively.

FIG. 5 , theanti-tilting portion 12 may be lath-shaped. Thefirst segment 131, thearc segment 132 and thesecond segment 133 are sequentially connected to form a near-semicircular structure and define, with theanti-tilting portion 12, an accommodating space for accommodating the suspension spring. Thesuspension spring 3 is hooked on thearc segment 132. Because vibration of atub assembly 4 in the washing machine is not completely periodic during laundry, in this case, thesuspension spring 3 may adaptively slide on thearc segment 132 according to a magnitude of the vibration, so that thesuspension spring 3 better relieves the vibration. - In an optional solution of this embodiment, the
suspension spring bracket 2 is a hollow structure, and is provided with abayonet 23 for mounting the suspension spring gasket 1. A circumferential wall on a side of thesuspension spring bracket 2 defining thebayonet 23 is bent to form the arc-shaped protrusion. When the suspension spring gasket 1 is mounted on thesuspension spring bracket 2, the arc-shaped protrusion abuts against the arc-shaped recess, and theanti-tilting portion 12 is located inside thesuspension spring bracket 2 and abuts against the buttingportion 22 of thesuspension spring bracket 2 to prevent the suspension spring gasket 1 from rotating around the arc-shaped protrusion. Specifically, as shown inFIG. 2, FIG. 3 andFIG. 4 , the buttingportion 22 is disposed inside thesuspension spring bracket 2. During mounting of the suspension spring gasket 1, theanti-tilting portion 12 may be first inserted through thebayonet 23 into the hollow structure inside thesuspension spring bracket 2 to abut against the buttingportion 22, and then the arc-shaped protrusion and the arc-shaped recess are abut together to mount the suspension spring gasket 1 on thesuspension spring bracket 2. The operation is simple and the mounting is stable and reliable. - In an optional solution of this embodiment, a circumferential wall on an other side of the
suspension spring bracket 2 defining thebayonet 23 is bent to form the buttingportion 22, and the buttingportion 22 and the arc-shaped protrusion are located on two opposite sides of thebayonet 23 respectively. A surface of the buttingportion 22 towards the interior of thesuspension spring bracket 2 forms a butting space for butting theanti-tilting portion 12. - Specifically, as shown in
FIG. 4 , the buttingportion 22 and themating portion 21 are disposed on two opposite sides of thebayonet 23 respectively. In this case, the force arm between the buttingportion 22 and themating portion 21 is the largest, and anti-tilting force moment of the buttingportion 22 acting on theanti-tilting portion 12 may be maximized, to achieve a better anti-tilting effect. - In addition, this embodiment further provides another structure of the suspension spring gasket 1. The suspension spring gasket 1 further includes an
insertion portion 14, and theinsertion portion 14 is disposed below thehook portion 13 along a height direction H of the suspension spring gasket 1; and theanti-tilting portion 12 is connected to thehook portion 13. - Specifically, as shown in
FIG. 10 , theanti-tilting portion 12 may be lath-shaped, and may be connected to thehook portion 13 through an indirect panel. Thehook portion 13 may be semicircular, which may also realize the functions of adaptive sliding and cushioning of thesuspension spring 3 on thehook portion 13 in response to different vibration of thetub assembly 4; moreover, theinsertion portion 14 may be inserted into theinsertion hole 24 of thesuspension spring bracket 2 to improve the mounting stability. - In an optional solution of this embodiment, the

The circumferential wall on a side of thesuspension spring bracket 2 defining theinsertion hole 24 is bent to form the arc-shaped protrusion that is ring-like. When the suspension spring gasket 1 is mounted on thesuspension spring bracket 2, the arc-shaped protrusion abuts against the arc-shaped recess, theinsertion portion 14 is inserted into theinsertion hole 24, and theanti-tilting portion 12 is located inside thesuspension spring bracket 2 and abuts against the buttingportion 22 of thesuspension spring bracket 2 to prevent the suspension spring gasket 1 from rotating around the arc-shaped protrusion. - Specifically, as shown in
FIG. 7, FIG. 8 andFIG. 9 , in this case, theinsertion portion 14, the abuttingportion 11 and theanti-tilting portion 12 in three potions act together to press and mount the suspension spring gasket 1 on thesuspension spring bracket 2. Theanti-tilting portion 12 abuts against the outside of thesuspension spring bracket 2 to play an anti-tilting function, to achieve the function of firmly mounting the suspension spring gasket 1 on thesuspension spring bracket 2. - In an optional solution of this embodiment, an outer wall of the
suspension spring bracket 2 forms the buttingportion 22, and the outer wall and the circumferential wall of thesuspension spring bracket 2 provided with theinsertion hole 24 are two opposite wall surfaces. - Similarly, the anti-tilting force arm between the butting
portion 22 and themating portion 21 is the largest, and the force moment of the buttingportion 22 acting on theanti-tilting portion 12 may be maximized, to achieve a better anti-tilting effect. - In an optional solution of this embodiment, an end of the
insertion portion 14 away from thehook portion 13 is further provided with a retainingedge 141. - Specifically, as shown in
FIG. 9 andFIG. 10 , the retainingedge 141 is preferably made of an elastic material. The retainingedge 141 may better fix theinsertion portion 14 to theinsertion hole 24 when theinsertion portion 14 is inserted into the insertion hole, thereby improving the mounting stability. - The foregoing descriptions are merely preferred embodiments of this application but are not intended to limit this application. This application may include various modifications and changes for a person skilled in the art. Any modification, equivalent replacement, or improvement made without departing from the spirit and principle of this application shall fall within the protection scope of this application.
