[0043] As shown in Figures 1 to 6 A washing machine disc seat structure according to the present application comprises a disc seat body 1, and a damper 3 is arranged on the disc seat body 1.

[0044] An upper cover 2 is arranged on the disc seat body 1, and a connecting arm 21 is arranged on the rear side of the upper cover 2. A hinge seat 4 is arranged in the connecting arm 21.

[0045] The pin shaft of the damper 3 is inserted into the hinge seat 4, so that the upper cover 2 is rotatably connected to the disc seat body 1 around the axis of the pin shaft of the damper 3.

[0046] Preferably, the connecting arm 21 extends outwardly in a direction perpendicular to the rear side of the upper cover 2. A protruding portion 10 protruding from the upper surface of the disc seat body 1 is arranged on the disc seat body 1. The connecting arm 21 is at least partially arranged opposite to the protruding portion 10 in the extending direction. The damper 3 and the hinge seat 4 are arranged on the opposite side walls, respectively.

[0047] In the present application, the protruding portion 10 protruding upwardly is arranged on the disc seat body 1. The protruding portion 10 is a hollow structure, and various electrical components can be arranged inside the protruding portion 10. The disc seat body 1 has a clothes feeding opening, which is closed by the upper cover 2. In order to ensure that the upper cover 2 is connected to the disc seat body 1 perfectly, the structure of the upper cover 2 needs to be designed to avoid the protruding portion 10 on the disc seat body 1.

[0048] The upper cover 2 is provided with two connecting arms 21 on the side wall of the protruding part 10, the connecting arms 21 extend away from the rear side wall of the upper cover 2 and are opposite to the side wall of the protruding part 10, that is, the protruding part 10 has a coincident part in the vertical direction of the extension direction of the connecting arms 21. In the coincident part, the connecting arms 21 are provided with a hinge seat 4, and the disc seat body 1 is provided with a damper 3, and the pin shaft in the damper 3 is connected with the hinge seat 4, so that the upper cover 2 can be rotatably connected with the disc seat body 1 under the premise of avoiding the protruding part 10 of the disc seat body 1.

[0049] However, the connecting arms 21 are provided on the upper cover 2 to form a long-arm type upper cover structure, and the existing connecting mode of the upper cover 2 and the disc seat body 1 is basically to provide the damper 3 on the connecting arm 21 and provide the hinge seat 4 connected with the damper 3 on the side wall of the disc seat body 1. Since the connecting arm 21 is in a long strip shape and connects the whole upper cover 2 to rotate, the strength and space of the connecting arm 21 are limited, and after a larger cavity or mounting groove for mounting the damper 3 is provided, the structural strength of the whole connecting arm 21 is smaller and cannot bear the pressure of opening the upper cover 2. However, the damper 3 and the hinge seat 4 are newly installed on the disc seat body 1 and the upper cover 2, so that the damper connection structure between the long-arm type upper cover 2 and the disc seat body 1 can guarantee the pressure to be borne by the upper cover 2 when normally opened and guarantee the service life of the upper cover 2. Specifically, the material of the hinge seat in the upper cover 2 can be nylon + glass fiber or a zinc alloy metal material, so as to further improve the structural strength of the hinge seat.

[0050] Specifically, the longitudinal section of the side wall of the protruding part 10 is in a triangular shape, or the upper surface of the protruding part 10 is gradually inclined from the side close to the upper cover to the side away from the upper cover. The two connecting arms 21 and the upper cover 2 form an avoiding opening, which can at least partially wrap the side wall of the protruding part 10, so as to facilitate the installation of the damper 3 and the hinge seat 4. In addition, due to the inclined arrangement of the upper surface of the protruding part 10, the display and other components arranged on the upper surface are convenient for users to observe, and the display and other components are convenient for avoiding during the rotation of the upper cover 2.

[0051] Specifically, the protruding part 10 is provided with protruding blocks 10a on both sides, the protruding blocks 10a are located on the front side of the connecting arms 21 and are used for limiting the extension length of the connecting arms 21, so as to prevent the connecting arms 21 from directly extending to the rear side of the whole disc seat body 1, so that the extension end of the connecting arms 21 will touch the wall surface when the upper cover 2 is opened. The protruding blocks 10a and the upper side of the disc seat 1 form a space for accommodating the upper cover 2 with the connecting arms 21, so that the disc seat 1 and the upper cover 2 have high connection and cooperation degree and are more beautiful.

[0052] Further, the hinge seat 4 comprises a hinge plate 42 and a hinge sleeve 41.

[0053] The hinge plate 42 is fixedly arranged in the upper cover 2, and extends outward along a direction perpendicular to the axial direction of the pin shaft of the damper 3.

[0054] The hinge sleeve 41 is arranged on the hinge plate 42, and the pin shaft of the damper 3 is at least partially arranged in the hinge sleeve 41.

[0055] In the present application, the hinge plate 42 is a plate-shaped structure and is arranged on the upper cover 2 in a fit manner. The hinge plate 42 has a certain extension length, and the extension direction is perpendicular to the axial direction of the pin shaft of the damper 3. The hinge plate 42 can extend to both sides perpendicular to the direction of the pin shaft of the damper 3, or at least the hinge plate 42 extends from the position of the pin shaft of the damper 3 to the rear side of the hinge plate 42. The hinge sleeve 41 is arranged at the middle or corner of the hinge plate 42, and the two can be integrally injection molded. The hinge sleeve 41 is provided with a shaft hole 41a, and the opening section of the shaft hole 41a is square, and the pin shaft of the damper 3 matches the shaft hole 41a. Thus, during the rotation of the upper cover 2, the pin shaft in the damper 3 can rotate with it, and the related components in the damper 3 are activated.

[0056] Further, the upper cover 2 is provided with an annular surrounding edge 22, and the upper cover 2 is provided with a convex plate 23 inside the annular surrounding edge 22, and an annular groove 24 is formed between the outer peripheral wall of the convex plate 23 and the inner peripheral wall of the annular surrounding edge 22.

[0057] The opposite plate surface of the hinge plate 42 and the upper cover 2 is provided with a recess 42a, forming a limiting surrounding edge 42b matched with the annular groove 24.

[0058] In the present application, the upper side of the upper cover 2 is provided with an annular surrounding edge 22 with a height, and the upper cover 2 inside the annular surrounding edge 22 is provided with a convex plate 23 protruding upward, and the protruding height of the convex plate 23 is less than or equal to the protruding height of the annular surrounding edge 22. The outer peripheral wall of the convex plate 23 and the inner peripheral wall of the annular surrounding edge 22 jointly form the annular groove 24.

[0059] The side opposite to the upper cover 2 of the hinge plate 42 is provided with a recess 42a, so that a limiting surrounding edge 42b is formed at the edge of the hinge plate 42, when the hinge plate 42 is installed in the upper cover, the limiting surrounding edge 42b is inserted into the annular groove 24. The inner and outer circumferential walls of the limiting surrounding edge 42b are respectively matched with the two annular groove walls of the annular groove 24, so that the hinge plate 42 in the horizontal direction of the upper cover 2 can be effectively limited. Thus, the upper cover 2 is prevented from shaking during rotation. At the same time, the limiting surrounding edge 42b can be matched with the annular groove 24 to position the hinge plate 42 before assembly.

[0060] Further, the inner wall of the annular surrounding edge 22 opposite to the corresponding damper 3 is provided with a plurality of supporting ribs 22a, the outer wall of the limiting surrounding edge 42b is matched with the supporting ribs 22a, and there is a gap between the inner wall of the limiting surrounding edge 42b and the protruding plate 23.

[0061] In the assembly relationship between the hinge plate 42 and the upper cover 2, the inner wall of the annular surrounding edge 22 opposite to the corresponding damper 3 is provided with a supporting rib 22a protruding towards the damper 3. Figure 4 At this time, the supporting rib 22a is arranged on the inner wall of the left side of the annular surrounding edge 22. When the hinge plate 42 is installed into the annular surrounding edge 22, the limiting surrounding edge 42b on the hinge plate 42 is extruded and matched with the supporting rib 22a, so that the entire hinge plate 42 has a tendency to be extruded towards the damper 3. Since the upper cover 2 is provided with the connecting arm 21 and the hinge plate 42 symmetrically, the upper cover 2 is effectively limited, so that the left and right movement of the upper cover 2 is prevented.

[0062] Further, the protruding plate 23 is provided with at least one transverse and / or vertical strip-shaped opening 25, and the strip-shaped opening 25 is communicated with the annular groove 24.

[0063] The plate surface of the hinge plate 42 opposite to the upper cover 2 is provided with at least one first limiting strip 43 matched with the strip-shaped opening 25.

[0064] In the present application, the protruding plate 23 is provided with at least one transverse or vertical strip-shaped opening 25, or both transverse and vertical strip-shaped openings 25, wherein the two ends of the strip-shaped opening 25 arranged on the protruding plate 23 extend to be communicated with the annular groove 24. The depth of the strip-shaped opening 25 towards the plate surface of the upper cover 2 can be flush with the groove bottom of the annular groove 24.

[0065] A first limiting strip 43 is arranged in the limiting surrounding edge 42b of the hinge plate 42 and matches the strip-shaped opening 25, when the first limiting strip 43 is completely inserted into the strip-shaped opening 25, the recess 42a in the hinge plate 42 just matches the surface of the convex plate 23, and the double limiting of the annular recess 24 and the limiting surrounding edge 42b further guarantees the assembly precision of the hinge plate 42 on the upper cover 2, and guarantees that the hinge plate 42 does not shake due to the torsion during the rotation of the upper cover 2.

[0066] Further, the upper cover 2 is internally provided with a shaft sleeve mounting groove 28, one side of the shaft sleeve mounting groove 28 extends to and penetrates through the opposite side wall of the annular surrounding edge 22, and the groove bottom of the shaft sleeve mounting groove 28 is provided with a transverse and / or vertical first limiting groove 29.

[0067] The side wall of the hinge shaft sleeve 41 is provided with a second limiting strip 41b matching the first limiting groove 29.

Alternatively, the annular surrounding edge 22 is directly profiled into a notch from top to bottom by the profiling process, and then the operation is continued downward, so that the convex plate 23 even acts on the side wall of the upper cover 2, thereby forming the shaft sleeve mounting groove 28.

[0069] Specifically, the groove bottom of the shaft sleeve mounting groove 28 is further provided with a transverse or vertical or both first limiting groove 29. The side wall opposite to the shaft sleeve mounting groove 28 of the hinge shaft sleeve 41 is provided with a second limiting strip 41b corresponding to the first limiting groove 29, so that after the hinge plate 42 is installed, the hinge shaft sleeve 41 and the shaft sleeve mounting groove 28 and the second limiting strip 41b and the first limiting groove 29 are further positioned and limited, thereby further ensuring the precise assembly of the hinge plate 42 on the upper cover 2.

[0070] Further, a plurality of first screw holes 44, 26 are respectively and intermittently arranged on the hinge plate 42 and the convex plate 23, and the plurality of first screw holes 44, 26 are arrayed on the plate surface of the hinge plate 42 and the convex plate 23.
