[0060] [Washing Machine Drive Installation Structure]

[0061] This embodiment discloses a washing machine drive installation structure. The washing machine includes a reducer and a drain motor. The reducer is connected to a brake arm 200, and the drain motor is connected to a connecting arm 100.

[0062] Refer to the structural schematic diagram of connecting arm 100 Figure 6The connecting arm 100 has four peripheral walls 140 connected in sequence, which form a through cavity 130, and the two ends of the through cavity 130 are connected.

[0063] The specific driver installation structure is as follows, refer to... Figures 3 to 5 ,in Figure 4 This is a schematic diagram of the structure after the brake arm 200 and the connecting arm 100 are assembled. Figure 5 This is a structural diagram illustrating the assembly process of the brake arm 200 and the connecting arm 100. The connecting arm has a first positioning part 110 and a second positioning part 120 on its peripheral wall 140, and the brake arm 200 has a third positioning part 210 and a fourth positioning part 220. The brake arm 200 is inserted into the through cavity 130 of the connecting arm 100.

[0064] The first positioning part 110 and the third positioning part 210 are inserted and engaged to limit the displacement of the brake arm 200 along the axial direction P1 of the penetrating inner cavity 130.

[0065] The second positioning part 120 and the fourth positioning part 220 abut against each other to limit the displacement of the brake arm 200 in the direction P2 perpendicular to the through cavity 130.

[0066] This application achieves a fixed connection between the brake arm 200 and the connecting arm 100 through one insertion and one abutment, without the need for auxiliary tools such as screws or fixing pins. During installation, simply insert the brake arm 200 into the connecting arm 100 in the specified direction to complete the insertion between the first positioning part 110 and the third positioning part 210, and the abutment between the second positioning part 120 and the fourth positioning part 220. This makes installation convenient and greatly improves installation efficiency.

[0067] Furthermore, the increased interaction points between the brake arm 200 and the connecting arm 100 improve the fixation reliability between them.

[0068] By inserting the first positioning part 110 and the third positioning part 210, and by abutting the second positioning part 120 and the fourth positioning part 220, the connection between the connecting arm 100 and the brake arm 200 can be fully limited, and the two cannot undergo relative lateral displacement, longitudinal displacement or rotation, making the connection structure more stable and reliable.

[0069] During the installation of the drive structure, the connecting arm 100 and the brake arm 200 first undergo relative lateral movement (specifically along the axial direction of the brake arm 200). After the lateral movement is completed, they then undergo relative longitudinal movement (specifically along a direction perpendicular to the brake arm 200). With the continuous relative longitudinal movement between them, the insertion between the first positioning part 110 and the third positioning part 210, and the abutment between the second positioning part 120 and the fourth positioning part 220 are simultaneously achieved, thus completing the installation. The entire process is seamless and the operation is simple and convenient.

[0070] Regarding the specific insertion structure between the brake arm 200 and the connecting arm 100, in some embodiments of this application, the first positioning part 110 is a post 111 provided on the peripheral wall 140 of the connecting arm, and the outer peripheral contour of the post 111 has at least one planar segment. The third positioning part 210 is a socket 211 provided on the brake arm 200.

[0071] The insertion post 111 is fitted into the insertion port 211 to limit the displacement of the brake arm 200 along the axial direction P1 through the inner cavity 130.

[0072] The outer periphery of the insertion post 111 has at least one planar segment, which can restrict the rotational movement of the insertion post 111 after it is inserted into the socket 211.

[0073] In some embodiments of this application, the insert 111 is a square post and the socket 211 is a square opening, which facilitates processing and insertion.

[0074] In some embodiments of this application, the insertion post 111 has a tapered structure from its root to its free end, which plays a motion guiding role in the insertion process between the insertion post 111 and the socket 211, making the insertion process smoother.

[0075] In other embodiments (not shown), the first positioning part 110 can be an insertion port provided on the peripheral wall 140 of the connecting arm, and the third positioning part 210 can be a post provided on the brake arm 200, which can also realize the insertion and fixing between the brake arm 200 and the connecting arm 100.

[0076] Regarding the specific abutment structure between the brake arm 200 and the connecting arm 100, in some embodiments of this application, the second positioning part 120 consists of two elastic claws 121 disposed on the peripheral wall 130 of the connecting arm. The two elastic claws 121 are arranged opposite to each other, and the peripheral wall where the two elastic claws 121 are located is directly opposite to the peripheral wall where the first positioning part 110 (specifically the insert post 111) is located.

[0077] During installation, refer to Figure 7 and Figure 8 First, insert the brake arm 200 into the through cavity 130 through the gap between the two elastic claws 121.

[0078] Then, refer to Figure 5 and Figure 9 During the process of the brake arm 200 moving toward the first positioning part 110 so that the first positioning part 110 and the third positioning part 210 are engaged, the elastic claw 121 is deformed by the pressure of the brake arm 200 and opens toward the two side peripheral walls 140.

[0079] Finally, refer to Figure 4 and Figure 10After the first positioning part 110 and the third positioning part 210 are inserted into place, the brake arm 200 moves out from the gap between the two elastic claws 121. The elastic claws 121 are no longer squeezed by the brake arm 200. The elastic claws 121 are reset and abut against the side wall of the brake arm 200, pressing the brake arm 200 against the peripheral wall where the first positioning part 110 is located, so as to limit the displacement of the brake arm 200 in the direction P2 perpendicular to the through cavity 130.

[0080] The elastic claw 121 is designed so that, on the one hand, it does not interfere with the insertion action between the brake arm 200 and the connecting arm 100. On the other hand, when the elastic claw 121 abuts against the brake arm 200, the brake arm 200 is difficult to disengage in reverse due to the structural restriction of the elastic claw 121, which greatly improves the reliability of the connection between the two.

[0081] In some embodiments of this application, the brake arm 200 includes a first sidewall 230 connected in sequence and a second sidewall 240 disposed on the left and right sides of the first sidewall 230, wherein the first sidewall 230 and the two second sidewalls 240 form a U-shaped structure.

[0082] The first sidewall 230 is provided with a third positioning part 210, that is, the first sidewall 230 is provided with an insertion port 211.

[0083] The second sidewall 240 forms the fourth positioning part 220, and the free end of the elastic claw 121 abuts against the second sidewall 240.

[0084] The fourth positioning part 220 does not need to be set up separately. By using the existing side wall of the brake arm 200, the elastic claw 121 can be pressed against the side wall of the brake arm 200 to achieve the abutment structure between the two.

[0085] Furthermore, through the abutting action of the elastic claw 121 against the two second side walls 240 on the left and right, the brake arm 200 can be tightly pressed against the peripheral wall of the connecting arm 100, further ensuring the reliability of the connection between the two.

[0086] In some embodiments of this application, the root of the elastic claw 121 is located at the corner intersection of two adjacent peripheral walls 140 of the connecting arm 100, maximizing the gap between the two elastic claws 121 to facilitate the insertion of the brake arm 200.

[0087] In some embodiments of this application, the free end of the elastic claw 121 has an arc-shaped structure, which facilitates the free end of the elastic claw 121 to spring open along the upper surface of the second sidewall 240, thereby improving the smoothness of the entire installation process.

[0088] In actual processing, the existing structure of the connecting arm 100 can be fully utilized, and the first positioning part 110 and the second positioning part 120 can be integrally formed on the inner wall of the connecting arm 100. This is easy to process, low in cost, and has a reliable structure.

[0089] In actual processing, the existing structure of the brake arm 200 can be fully utilized, and the third positioning part 210 can be integrally machined on the inner wall of the brake arm 200. The fourth positioning part 220 can be directly machined from the existing side wall of the brake arm 200, which is convenient to process, low in cost, and reliable in structure.

[0090] In other embodiments (not shown), the second positioning part 120 can be a snap-fit ​​structure provided on the peripheral wall 140 of the connecting arm, and the fourth positioning part 220 can be a bayonet structure provided on the side wall of the brake arm 200. When the brake arm 200 and the connecting arm 100 are inserted into place, the snap-fit ​​structure and the bayonet structure cooperate to achieve the same limiting effect on the brake arm 200.
