Description

Technical Field

[0001] The present application relates to the technical field of electrical appliance manufacturing, and in particular to a hinge assembly and a clothing processing device. Background Art

[0002] Among modern household appliances, drum washing machines have become the mainstream washing equipment due to their efficient washing effect and low clothing wear rate. Drum washing machines usually include a drum, a box that accommodates the drum, and a door that covers the front opening of the box. The box and door of the drum washing machine are usually connected by a hinge assembly to achieve rotation.

[0003] However, existing hinge assemblies usually lack a damping and buffering design, resulting in a lack of damping during the opening and closing process of the door body, which in turn leads to a poor user feel. When the user opens the door, the pushed-open door body may over-open under the action of inertia due to the lack of damping, and hit the side of the box or adjacent objects (such as walls), causing damage to the edge of the door body. When the user closes the door, the door body accelerates to close under the action of the thrust, and the lack of damping and buffering will directly hit the door frame, generating obvious noise (such as a "bang" sound) and a stiff feel (similar to the feeling of "hitting the wall"). Summary of the Invention

[0004] Based on this, an embodiment of the present application provides a hinge assembly and a clothing processing device.

[0005] In a first aspect, an embodiment of the present application provides a hinge assembly, comprising:

[0007] A hinge blade, the hinge blade comprising a blade body, the blade body being rotatably connected to the hinge seat, the blade body having a third end face and a fourth end face arranged opposite to each other, the third end face being provided with a first protrusion;

[0008] a first elastic piece disposed in the first guide groove, forming a first channel between the first elastic piece and the first side wall, the first elastic piece including alternating first protruding structures and first recessed structures, the first protruding structures protruding toward the first side wall, and the first recessed structures recessed away from the first side wall;

[0009] When the blade body rotates relative to the hinge seat, the first protrusion moves in the first channel.

[0010] In some embodiments, the first side wall and the second side wall are both arc-shaped, and the center of the circle where the first side wall is located coincides with the center of the circle where the second side wall is located.

[0011] In some embodiments, the first side wall is located outside the second side wall, and the first elastic sheet is sleeved on the second side wall.

[0012] In some embodiments, in the first elastic piece, there are a plurality of first protruding structures and a plurality of first concave structures.

[0013] In some embodiments, the hinge assembly also includes a rotating shaft; a first through hole is provided on the blade body, a first recess is provided on the first end face of the hinge seat, and the first guide groove is arranged around the first recess; the rotating shaft passes through the first through hole, and one end of the rotating shaft enters the first recess.

[0014] In some embodiments, the hinge assembly further includes a first limiting cover, which is disposed between the blade body and the first end surface of the hinge seat and is used to limit the up and down movement of the first elastic piece;

[0015] The first limiting cover is provided with a first guide hole, and the first guide hole is arranged corresponding to the first guide groove.

[0016] In some embodiments, a second guide groove is provided on the second end surface of the hinge seat, and the second guide groove has a third side wall and a fourth side wall that are oppositely arranged;

[0017] A second protrusion is provided on the fourth end surface of the blade body;

[0018] The hinge assembly further includes a second elastic piece disposed in the second guide groove, forming a second channel between the second elastic piece and the third side wall, the second elastic piece including a second protruding structure and a second concave structure alternately arranged, the second protruding structure protruding toward the third side wall, and the second concave structure concave toward the direction away from the third side wall;

[0019] When the blade body rotates relative to the hinge seat, the second protrusion moves in the second channel.

[0020] In some embodiments, the hinge assembly further includes a second limiting cover, which is disposed between the blade body and the second end surface of the hinge seat and is used to limit the up and down movement of the second elastic piece;

[0021] The second limiting cover is provided with a second guide hole, and the second guide hole is arranged corresponding to the second guide groove.

[0022] In some embodiments, the third side wall and the fourth side wall are both arc-shaped, and the center of the circle where the third side wall is located coincides with the center of the circle where the fourth side wall is located; and / or,

Since the first spring plate includes alternating first protrusions and first recesses, when the first protrusion on the hinge blade moves between the first protrusion and the first sidewall, the first protrusion experiences greater resistance during movement due to the smaller distance between the first protrusion and the first sidewall, thereby generating a damping effect on the rotation of the hinge blade. When the first protrusion on the hinge blade moves between the first recess and the first sidewall, the first protrusion becomes lodged within the first recess, i.e., the first recess serves as a hovering position during the rotation of the hinge blade. Since the hinge assembly can generate a damping effect during use, when the hinge assembly is used to connect a cabinet and a door in a clothing processing device, it can enhance the user's door opening and closing feel and prevent the door from being knocked due to excessive opening or accelerated closing due to inertia.

[0047] See also Figure 1 、 Figure 2 and Figure 3 , an embodiment of the present application provides a hinge assembly 100 , including a hinge seat 10 , a hinge blade 20 and a first elastic piece 30 .

[0048] See also Figure 3 and Figure 4 The hinge seat 10 is provided with a mounting opening 11, the mounting opening 11 having a first end surface 111 and a second end surface 112 arranged opposite to each other, the first end surface 111 is provided with a first guide groove 101, see Figure 4 and Figure 10 The first guide groove 101 has a first side wall 71 and a second side wall 72 that are oppositely arranged.

[0049] See also Figure 5 The hinge blade 20 includes a blade body 21, which is rotatably connected to the hinge seat 10. The blade body 21 has a third end face 213 and a fourth end face 214 that are oppositely arranged, and a first protrusion 201 is provided on the third end face 213.

[0050] See also Figure 8 、 Figure 9 and Figure 10 The first elastic piece 30 is disposed in the first guide groove 101 , and a first channel 105 is formed between the first elastic piece 30 and the first side wall 71 , see Figure 6 and Figure 10 The first elastic piece 30 includes a first protruding structure 31 and a first concave structure 32 that are alternately arranged. The first protruding structure 31 protrudes toward the direction close to the first side wall 71, and the first concave structure 32 is concave toward the direction away from the first side wall 71.

[0051] When the blade body 21 rotates relative to the hinge seat 10 , the first protrusion 201 moves in the first channel 105 .

[0052] It is understandable that when the blade body 21 rotates relative to the hinge seat 10 , the first protrusion 201 rotates accordingly. When the position of the rotation axis remains unchanged, the rotation trajectory of the first protrusion 201 is in an arc shape.

[0053] Exemplarily, the first protruding structure 31 and the first concave structure 32 are both arc-shaped.

[0054] The hinge assembly 100 provided in the embodiment of the present application is provided with a first guide groove 101 on the first end surface 111 of the hinge seat 10, and a first spring piece 30 is provided in the first guide groove 101, so that a first channel 105 is formed between the first spring piece 30 and the first side wall 71 of the first guide groove 101. Since the first spring piece 30 includes the first protruding structure 31 and the first concave structure 32 arranged alternately, when the first protruding portion 201 on the hinge blade 20 moves to the first protruding structure 31, the first channel 105 is formed between the first spring piece 30 and the first side wall 71 of the first guide groove 101. 1 and the first side wall 71, due to the small distance between the first protrusion structure 31 and the first side wall 71, the first protrusion 201 experiences greater resistance during movement, resulting in a damped feeling in the rotation of the hinge blade 20. When the first protrusion 201 on the hinge blade 20 moves between the first recessed structure 32 and the first side wall 71, the first protrusion 201 becomes lodged within the first recessed structure 32. In other words, the first recessed structure 32 represents the hovering position during the rotation of the hinge blade 20. Because the hinge assembly 100 can generate a damped feeling during use, when the hinge assembly 100 is used to connect the cabinet and door body of a clothing processing device 200, it can enhance the user's feel when opening and closing the door, and avoid the occurrence of impact caused by excessive opening or accelerated closing of the door body due to inertia.

[0055] See also Figure 4 and Figure 10 The first side wall 71 and the second side wall 72 are both arc-shaped, and the center of the circle where the first side wall 71 is located coincides with the center of the circle where the second side wall 72 is located.

[0056] It can be understood that when the first side wall 71 and the second side wall 72 are both arc-shaped, that is, the first guide groove 101 is arc-shaped, since when the blade body 21 rotates relative to the hinge seat 10, the first protrusion 201 rotates accordingly, and when the position of the rotation axis remains unchanged, the rotation trajectory of the first protrusion 201 is arc-shaped. Therefore, by designing the first guide groove 101 to be arc-shaped, the smooth rotation of the first protrusion 201 can be achieved.

[0057] See also Figure 4 and Figure 10 The first side wall 71 is located at the periphery of the second side wall 72, and the first elastic piece 30 is sleeved on the second side wall 72. Exemplarily, the first elastic piece 30 abuts against the second side wall 72.

[0058] It can be understood that when the first side wall 71 is located outside the second side wall 72, it means that the first side wall 71 is the outer wall of the first guide groove 101, and the second side wall 72 is the inner wall of the first guide groove 101, that is, the first spring piece 30 abuts against the inner wall of the first guide groove 101, thereby forming a first channel 105 between the first spring piece 30 and the outer wall of the first guide groove 101 to allow the first protrusion 201 to move.

[0059] It is understandable that, since the first elastic piece 30 is elastic, the elasticity of the first elastic piece 30 can be utilized to tightly clamp the first elastic piece 30 on the second side wall 72 .

[0060] In some other embodiments, the first elastic piece 30 may also abut against the outer wall of the first guide groove 101 , thereby forming a second channel between the first elastic piece 30 and the inner wall of the first guide groove 101 to allow the first protrusion 201 to move.

[0061] See also Figure 6 In the first elastic piece 30, the number of the first protrusion structures 31 is multiple, and the number of the first recessed structures 32 is multiple.

[0062] In the embodiments of the present application, a plurality refers to two or more, for example, three, four, five, six, seven, eight, etc.

[0063] It can be understood that when the number of the first recessed structures 32 is multiple, it means that the hinge blade 20 has multiple hovering positions during the rotation process. When the hinge assembly 100 is applied to a clothing processing device (such as a washing machine), it means that the door body has multiple hovering positions during the rotation process, so that the clothing processing device can achieve multiple gears of door opening angle limit hovering after opening the door, so that users can conveniently choose different door opening angles for hovering, thereby improving user experience.

[0064] See also Figure 6 In some embodiments, in the first spring piece 30, the number of the first protruding structures 31 is four, the number of the first recessed structures 32 is three, and the three first recessed structures 32 are respectively a door-closing hovering position, a middle hovering position, and a door-opening hovering position.

[0065] See also Figure 8 、 Figure 9 and Figure 10 , Figure 10Three hovering positions of the first protrusion 201 in the first channel 105 are shown, wherein when the first protrusion 201 is in the first position 2A, the door body of the clothing processing device 200 is in a closed state; when the first protrusion 201 is in the second position 2B, the door body of the clothing processing device 200 is in an open state and is located in an intermediate hovering position between the maximum door opening angle and the door closing; when the first protrusion 201 is in the third position 2C, the door body of the clothing processing device 200 is in an open state and is located at the maximum door opening angle.

[0066] See also Figure 3 The hinge assembly 100 further includes a rotating shaft 40; see Figure 5 The blade body 21 is provided with a first through hole 203, see Figure 4 A first recessed portion 102 is provided on the first end surface 111 of the hinge seat 10 , and the first guide groove 101 is arranged around the first recessed portion 102 ; the rotating shaft 40 passes through the first through hole 203 , and one end of the rotating shaft 40 enters the first recessed portion 102 .

[0067] It is understood that by providing a rotating shaft 40, the rotating shaft 40 passes through the first through hole 203 on the blade body 21, and one end of the rotating shaft 40 enters the first recessed portion 102 on the hinge seat 10, so that the blade body 21 can rotate around the rotating shaft 40, thereby realizing the rotational connection between the blade body 21 and the hinge seat 10. Exemplarily, the first recessed portion 102 can be a groove or a through hole.

[0068] See also Figure 3 and Figure 7 The hinge assembly 100 also includes a first limit cover 50, which is arranged between the blade body 21 and the first end surface 111 of the hinge seat 10, and is used to limit the up and down movement of the first elastic piece 30; the first limit cover 50 is provided with a first guide hole 51, and the first guide hole 51 is arranged corresponding to the first guide groove 101.

[0069] It is understandable that by providing the first limiting cover 50 , the first limiting cover 50 and the bottom surface of the first guide groove 101 can be used to limit the first elastic piece 30 from upper and lower positions respectively, thereby preventing the first elastic piece 30 from moving up and down.

[0070] It is understandable that by providing the first guide hole 51 on the first limiting cover 50 and making the first guide hole 51 correspond to the first guide groove 101 , the first protrusion 201 can be allowed to pass through the first guide hole 51 and enter the first guide groove 101 .

[0071] See also Figure 7For example, the first limiting cover 50 is further provided with a second through hole 52 corresponding to the first recessed portion 102 , the first guide hole 51 is arranged around the second through hole 52 , and the rotating shaft 40 passes through the second through hole 52 .

[0072] Exemplarily, a second guide groove is provided on the second end face 112 of the hinge seat 10, and the second guide groove has a third side wall and a fourth side wall arranged opposite to each other; a second protrusion 202 is provided on the fourth end face 214 of the blade body 21; the hinge assembly 100 also includes a second elastic piece 61, which is arranged in the second guide groove, and a second channel is formed between the second elastic piece 61 and the third side wall, and the second elastic piece 61 includes a second protrusion structure and a second recessed structure arranged alternately, the second protrusion structure protrudes in a direction close to the third side wall, and the second recessed structure is recessed in a direction away from the third side wall; when the blade body 21 rotates relative to the hinge seat 10, the second protrusion 202 moves in the second channel.

[0073] Exemplarily, the second protruding structure and the second concave structure are both arc-shaped.

[0074] Exemplarily, a second recessed portion is provided on the second end surface 112 of the hinge seat 10 , and the second guide groove is arranged around the second recessed portion; the other end of the rotating shaft 40 enters the second recessed portion.

[0075] Illustratively, the second recessed portion may be a groove or a through hole.

[0076] Exemplarily, the hinge assembly 100 also includes a second limit cover 62, which is arranged between the blade body 21 and the second end face 112 of the hinge seat 10, and is used to limit the up and down movement of the second spring piece 61; the second limit cover 62 is provided with a second guide hole, and the second guide hole is arranged corresponding to the second guide groove.

[0077] Illustratively, the second limiting cover 62 is further provided with a third through hole corresponding to the second recessed portion, the second guide hole is arranged around the third through hole, and the rotating shaft 40 passes through the third through hole.

[0078] It can be seen that the present application connects the hinge seat 10 , the hinge blade 20 , the first limiting cover 50 and the second limiting cover 62 together by using the rotating shaft 40 , thereby enabling the hinge assembly 100 to achieve screw-free connection.

[0079] Exemplarily, the third side wall and the fourth side wall are both arc-shaped, and the center of the circle where the third side wall is located coincides with the center of the circle where the fourth side wall is located.

[0080] Exemplarily, the third side wall is located at the periphery of the fourth side wall.

[0081] Exemplarily, the second elastic piece 61 is sleeved on the fourth side wall.

[0083] Illustratively, in the second elastic piece 61 , the number of the second protruding structures is plural, and the number of the second concave structures is plural.

[0084] In some embodiments, the first end face 111 and the second end face 112 on the hinge seat 10 have the same structure, the first guide groove 101 and the second guide groove have the same structure, the first spring clip 30 and the second spring clip 61 have the same structure, and the first protrusion 201 on the third end face 213 of the blade body 21 and the second protrusion 202 on the fourth end face 214 have the same structure.

[0085] Exemplarily, the first end face 111 and the second end face 112 of the hinge seat 10 are respectively the lower end face and the upper end face of the mounting opening 11 , and the third end face 213 and the fourth end face 214 of the blade body 21 are respectively the lower end face and the upper end face of the blade body 21 .

[0086] Exemplarily, the first elastic piece 30 and the second elastic piece 61 are both made of metal.

[0087] Exemplarily, the first protrusion 201 and the second protrusion 202 are both cylindrical.

[0088] See also Figure 11 and Figure 12 , an embodiment of the present application further provides a clothing processing device 200, including a box body and a door body assembly 210, wherein the box body and the door body assembly 210 are rotatably connected through the hinge assembly 100, and the hinge assembly 100 is the hinge assembly 100 described above.
