[0036] Referring to Figures 1-4 , an embodiment of the washing machine door body connecting structure of the present application. The washing machine door body connecting structure is used to rotatably connect the washing machine door body 200 to the washing machine outer drum 100. The core improvement of the structure is the connection mode of the front end of the outer drum 100, which discards the traditional screw connection and adopts the injection-molded stud structure 111.

[0037] The washing machine door body connecting structure comprises an outer drum 100, a door body 200, a hinge assembly 300 and a fastener 400.

[0038] At least two stud structures 111 are arranged on the front end face of the outer tub 100. Each stud structure 111 includes a stud body and a threaded portion. The stud body is the base of the connection, one end of which is firmly connected to the front end face of the outer tub 100, and the other end extends out of the front end face of the outer tub 100 to form a support structure for connecting the hinge seat 310. The threaded portion is arranged at the outer end of the stud body for threaded connection with the fastener 400 (such as a nut).

[0039] The stud structure 111 is not a separate component that is fixed to the outer tub 100 by threaded connection or other means at a later stage, but is an integrally formed structure with the outer tub 100. The integrally formed design significantly improves the strength and stability of the connection, avoiding the problem of loose connection due to long-term use or vibration.

[0040] The door body 200 is rotatably connected to the front side of the outer tub 100 by the hinge assembly 300.

[0041] The hinge assembly 300 consists of two parts, the hinge seat 310 and the hinge 320.

[0042] The hinge seat 310 is provided with at least two mounting holes 3111, the position and size of which match the stud structure 111 at the front end of the outer tub 100, so that the hinge seat 310 can be stably mounted on the outer tub 100. One end of the hinge 320 is rotatably connected to the door body 200 by a rotating shaft or other means, and the other end is fixedly connected to the hinge seat 310 by screws, rivets or other means.

[0043] Finally, the fastener 400 is threaded with the threaded portion of the stud structure 111 to firmly fix the hinge seat 310 on the outer tub 100.

[0044] The above-described washing machine door body connection structure fixes the hinge through the integrally formed stud structure 111 at the front end of the outer tub 100. The weight of the door body 200 is no longer directly applied to the screw connection, but is evenly transmitted to the outer tub 100 through the stud structure 111, thereby effectively reducing the risk of sagging of the door body 200 and avoiding the collision problem of the locking hook and the locking hole when closing the door, improving the service life and reliability of the washing machine.

[0045] In order to further improve the stability of the connection between the hinge seat 310 and the outer tub 100 and prevent the hinge seat 310 from rotating or shifting, a positioning structure is arranged between the outer tub 100 and the hinge seat 310. The positioning structure can be realized in various forms, such as the cooperation of protrusions and grooves, the cooperation of positioning columns and positioning holes, etc. The positioning structure can provide additional support and constraint to ensure that the hinge seat 310 maintains a stable position during long-term use, thereby ensuring the normal opening and closing and sealing performance of the door body 200.

[0046] In the present embodiment, the positioning structure includes at least one positioning post 112 provided on the outer cylinder 100, and at least one positioning hole 3112 provided on the hinge base 310 and cooperating with the positioning post 112. The positioning post 112 is a protruding structure fixed on the outer cylinder 100, which can be cylindrical, square or other suitable shape. The positioning hole 3112 is a hole provided on the hinge base 310, which is matched in shape and size with the positioning post 112, so that the positioning post 112 can be accurately inserted into the positioning hole 3112. When the hinge base 310 is installed on the outer cylinder 100, the positioning post 112 is inserted into the positioning hole 3112, and through the cooperation between the two, the movement of the hinge base 310 in the horizontal and vertical directions, as well as the rotation around the axis of the stud, is effectively limited. The number, shape and position of the positioning post 112 and the positioning hole 3112 can be adjusted according to the specific structure and needs. For example, two or more positioning posts 112 and positioning holes 3112 can be provided to further improve the stability and reliability of the positioning. The material of the positioning post 112 can be the same as that of the outer cylinder 100, for example, it can be integrally formed with the outer cylinder 100 by injection molding.

[0047] In another embodiment, positioning posts can also be provided on the hinge base 310, and corresponding positioning holes can be provided on the outer cylinder 100.

[0048] In the present embodiment, the hinge base 310 includes two hinge base halves 310a / 310b. The split design of the hinge base 310 facilitates manufacturing and assembly, and the size and shape of the hinge base 310 can be adjusted as needed.

[0049] In the present embodiment, the hinge base 310 includes two hinge base halves 310a / 310b. The split design of the hinge base 310 facilitates manufacturing and assembly, and the size and shape of the hinge base 310 can be adjusted as needed.

[0050] Two mounting holes 3111 and at least one positioning hole 3112 are arranged on each hinge seat half 310a / 310b. The two mounting holes 3111 are arranged along the diagonal direction of the base portion 311, which can make the hinge seat half 310a / 310b more stably fixed on the outer cylinder 100, effectively disperse the stress, and improve the strength and stability of the connection. Through the arrangement along the diagonal direction, the space of the base portion 311 can be maximally utilized, and the strength of the base portion 311 caused by too concentrated mounting holes 3111 can be avoided. The positioning hole 3112 is arranged to cooperate with the positioning column on the outer cylinder 100, so as to further improve the positioning accuracy and stability of the hinge seat half. In the embodiment, two positioning holes 3112 are arranged, and the two positioning holes 3112 are also arranged along the diagonal direction of the base portion 311.

[0051] In the embodiment, the front end surface of the outer cylinder 100 is provided with a mounting portion 110, which is a region specially used for mounting the hinge seat 310. The mounting portion 110 is provided with the stud structure 111. In order to further improve the positioning accuracy and stability of the hinge seat 310, at least one positioning rib 120 is arranged around the mounting portion 110. The positioning rib 120 is a protruding strip structure on the front end surface of the outer cylinder 100, which is matched with the side wall of the hinge seat 310 in shape and position. When the hinge seat 310 is mounted on the outer cylinder 100, the side wall thereof abuts against the positioning rib 120, so as to limit the position of the hinge seat 310 and prevent the hinge seat 310 from rotating or shifting. The positioning rib 120 can be arranged at different positions of the mounting portion 110, such as the top, bottom or side.

[0052] In the embodiment, the stud structure 111 is a metal insert, which is fixed on the front end surface of the outer cylinder 100 by injection molding. The metal insert has high strength and rigidity, and can bear the weight of the door body 200 and various forces in the use process. Through injection molding, the metal insert can be firmly combined with the outer cylinder 100 to form an integral structure, which improves the reliability and stability of the connection. In addition, the metal insert can be used to conveniently control the size and accuracy of the stud structure 111, so as to ensure the mounting accuracy of the hinge seat 310. The material of the metal insert can be selected from steel, copper or other suitable metal materials.

[0053] In the embodiment, the fastener 400 is a nut, which is threadedly connected with the threaded portion of the stud structure 111 to firmly fix the hinge seat 310 on the outer cylinder 100. The shape and size of the nut can be selected according to the specific structure and needs.

[0054] In order to prevent the nut from loosening due to the vibration when the washing machine is running, the nut is preferably a locking nut, such as a nylon ring locking nut, a metal insert locking nut, a tooth-shaped locking nut, etc.

[0055] In another embodiment, a lock washer (not shown) can also be provided between the normal nut and the outer drum 100. The lock washer is a washer with a special structure that can increase the friction between the nut and the outer drum 100, or prevent the nut from loosening by mechanical locking.
