1-4, in some embodiments, a refrigerator hinge assembly includes: an upper cover plate 100, a lower cover plate 200, and a link member 300. The upper cover plate 100 is covered on the upper side wall of the refrigerator body 400, and the front side wall of the upper cover plate 100 is provided with a mounting opening 110; the lower cover plate 200 is disposed on the upper sidewall of the case 400, and the lower cover plate 200 is partially disposed in the mounting port 110; the link member 300 is partially disposed inside the upper cover plate 100, one end of the link member 300 is rotatably connected to the upper sidewall of the case 400, and the other end extends along the mounting port 110 to be connected to the door 500 of the refrigerator.

By adopting the refrigerator hinge assembly provided by the embodiment of the disclosure, the upper cover plate 100 is matched with the lower cover plate 200, the lower cover plate 200 is partially arranged in the mounting port 110 on the front side wall of the upper cover plate 100, and the lower cover plate 200 is utilized to further limit the area of the ash inlet region of the mounting port 110, so that the ash inlet region on the lower side of the connecting rod piece 300 is reduced. Thereby reducing the dust inlet area of the mounting port 110 of the front side wall of the upper cover plate 100, reducing the risk of dust and other impurities entering along the mounting port 110 without affecting the movement of the link member 300, preventing the link member 300 from being polluted by dust and other impurities, and prolonging the service life of the hinge assembly of the refrigerator.

Optionally, the upper cover plate 100 has a shell-shaped structure, an installation space 120 is defined between the inner wall of the upper cover plate 100 and the upper side wall of the box 400, a part of the link member 300 is disposed in the installation space 120, and the rest extends out along the installation opening 110 to be connected with the door 500. In this way, the link member 300 is partially disposed in the installation space 120, and the link member 300 disposed in the installation space 120 is protected by the upper cover plate 100 having a cover-like structure, so that foreign matters such as dust above are prevented from entering the installation space 120 to contaminate the link member 300.

Specifically, the lower cover plate 200 is partially located in the installation space 120, and the remaining portion extends into the installation opening 110. Thus, since the link member 300 is mounted, the distance between the lower side of the link member 300 and the upper side wall of the case 400 is constant. In order to avoid interference between the link member 300 and the upper side wall of the case 400, the distance between the lower side surface of the link member 300 and the upper side wall of the case 400 is generally large, and the distance between the lower side surface of the link member 300 at the mounting port 110 and the lower side edge of the mounting port 110 is also relatively large, so that impurities such as dust easily enter the mounting space 120 through the region between the lower side surface of the link member 300 and the lower side edge of the mounting port 110. Therefore, the lower cover plate 200 is provided, the rest of the lower cover plate 200 is extended into the mounting port 110, the region between the lower side surface of the link member 300 and the lower side edge of the mounting port 110 through the lower cover plate 200 is blocked, and the ash inlet region of the mounting port 110 is reduced.

Optionally, a hinge plate is provided on an upper sidewall of the case 400, and one end of the link member 300 is rotatably connected to the hinge plate. In this way, by providing the hinge plate at the upper sidewall of the case 400, one end of the link member 300 is rotatably connected with the hinge plate, thereby realizing the rotational connection between the door 500 and the case 400, and improving the stability of the rotation of the door 500.

Optionally, the upper side wall of the case 400 is provided with a through hole, and the hinge plate is installed in the through hole. In this way, the installation stability of the hinge plate is improved, thereby more stably supporting the link member 300, and thus the support stability of the door body 500 is improved.

Specifically, the hinge plate is disposed in the installation space 120.

Optionally, the front end of the upper cover plate 100 is provided with a routing convex shell 130, and the routing convex shell 130 protrudes from a plane where the front side wall of the box 400 is located in a direction where the door 500 is located. In this way, the wiring convex shell 130 extends to the upper side of the door body 500, so that wires in the box body 400 can be conveniently paved into the door body 500 along the wiring convex shell 130, the wires are protected through the wiring convex shell 130, the paved wires are tidier, and the abrasion of the wires is reduced.

Optionally, a wiring port is provided on the upper sidewall of the case 400. Thus, the wires in the case 400 enter the inside of the upper cover plate 100 through the routing ports, and then enter the door 500 along the routing convex case 130.

Specifically, the routing ports and the routing convex case 130 are both in communication with the installation space 120.

Alternatively, the link 300 includes: a first link 310 and a second link 320. The first connecting rod 310 is disposed inside the upper cover plate 100, and one end of the first connecting rod 310 is rotatably connected with the upper sidewall of the case 400; one end of the second link 320 is rotatably connected to the other end of the first link 310, and the other end extends out of the door body 500 along the mounting port 110. In this way, the link member 300 is divided into the first link 310 and the second link 320, one end of the first link 310 is rotatably connected to the upper sidewall of the case 400, the other end is rotatably connected to the second link 320, and one end of the second link 320 extends out of the door 500 along the mounting port 110 to be connected thereto, so that the rotation range of the link member 300 can be increased, thereby increasing the opening width of the door 500.

Specifically, one end of the first link 310 is rotatably coupled to a hinge plate of the upper sidewall of the case 400. Thus, since the first link 310 is disposed inside the upper cover plate 100, one end of the first link 310 is rotatably coupled to the upper sidewall of the case 400, and thus one end of the first link 310 is rotatably coupled to the hinge plate provided to the upper sidewall of the case 400.

Specifically, the first link 310 and the second link 320 are rotatably connected through a rotation shaft 330. In this way, the rotational stability of the first link 310 and the second link 320 can be improved, the second link 320 can be rotated with respect to the first link 310, and the rotational range of the second link 320 is increased, thereby increasing the opening width of the door 500.

Alternatively, the position where the first link 310 is rotatably connected with the second link 320 is located at the mounting port 110. In this way, the first link 310 can rotate in a larger range relative to the second link 320, so that the risk of interference with the side edge of the mounting port 110 when the first link 310 rotates is reduced, and the opening width of the door body 500 is increased.

Alternatively, the first link 310 is a straight bar structure, and the second link 320 is a curved bar structure. In this way, the first connecting rod 310 is arranged to be a straight rod structure, and a relatively firm support is formed by using the first connecting rod 310. Since the second connecting rod 320 extends out along the mounting port 110 and is connected with the door body 500, the second connecting rod 320 is located at the outside to rotate when the door body 500 rotates, so that the second connecting rod 320 is set to be in a curved bar structure, an external structure can be avoided, and the risk of interference between the second connecting rod 320 and the external structure is reduced.

Specifically, the second link 320 is a curved bar structure that is curved away from the routing convex case 130. In this way, the second connecting rod 320 can avoid the routing convex shell 130 of the upper cover plate 100 when rotating, and the risk of interference between the second connecting rod 320 and the routing convex shell 130 is reduced.

Alternatively, the thickness of the link member 300 is smaller than the height difference between the upper side of the mounting port 110 and the upper side wall of the lower cover plate 200 in the vertical direction. In this way, since one end of the link member 300 protrudes along the mounting port 110 to be connected to the door body 500, in order to avoid interference between the link member 300 and the upper and lower sides of the mounting port 110, the thickness of the link member 300 is set to be smaller than the height difference between the upper side of the mounting port 110 and the upper side wall of the lower cover plate 200, so that the link member 300 can smoothly rotate along the mounting port 110, thereby improving the rotational stability of the door body 500.

Specifically, the first link 310 is located below the second link 320, shaft holes are formed at opposite ends of the first link 310 and the second link 320, the rotating shaft 330 sequentially penetrates into the shaft holes of the second link 320 and the first link 310 from above the second link 320 to rotatably connect the second link 320 and the first link 310, an upper end of the rotating shaft 330 protrudes out of an upper side surface of the second link 320, and a lower end of the rotating shaft 330 is flush with a lower side surface of the first link 310.

It is understood that the thickness of the link 300 in the vertical direction refers to the height of the rotation shaft 330 connecting the first link 310 and the second link 320.

Alternatively, the distance between the upper end of the link member 300 and the upper side of the mounting port 110 in the vertical direction is one-fourth of the thickness of the link member 300. In this way, since the link member 300 connects the case 400 and the door 500, the link member 300 has a tendency to move downward without a tendency to move upward under the weight of the door 500. Therefore, the distance between the upper end of the link member 300 and the upper side of the mounting port 110 is set to be one-fourth of the thickness of the link member 300, which can not only ensure that the upper end of the link member 300 does not interfere with the upper side of the mounting port 110, but also reduce the dust inlet area of the mounting port 110.

L1 as shown in fig. 4 is a distance between the upper end of the link 300 and the upper side of the mounting port 110.

It will be appreciated that the upper end of the link 300 refers to the upper end of the rotation shaft 330.

Specifically, the distance between the upper end of the rotation shaft 330 and the upper side of the mounting opening 110 is one-fourth of the height of the rotation shaft 330.

Alternatively, a distance between the lower end of the link member 300 and the upper sidewall of the lower cover plate 200 in the vertical direction is equal to the thickness of the link member 300. Thus, since the link member 300 connects the case 400 and the door 500, the link member 300 has a tendency to move downward under the gravity of the door 500. The distance between the lower end of the link member 300 and the upper sidewall of the lower cover plate 200 is thus set to be equal to the thickness of the link member 300 such that the distance between the lower end of the link member 300 and the upper sidewall of the lower cover plate 200 is greater than the distance between the upper end of the link member 300 and the upper side of the mounting port 110, reducing the risk of the link member 300 interfering with the lower cover plate 200 under the weight of the door body 500.

L2 as shown in fig. 4 is a distance between the lower end of the link member 300 and the upper sidewall of the lower cover plate 200.

Specifically, the distance between the lower side of the first link 310 and the upper sidewall of the lower cover plate 200 is equal to the height of the rotation shaft 330. Thus, since the first link 310 is positioned below the second link 320 and the lower end surface of the rotation shaft 330 connecting the first link 310 and the second link 320 is flush with the lower side surface of the first link 310, the lower end of the link member 300 is the lower side surface of the first link 310. Since the thickness of the link member 300 in the vertical direction is the height of the rotation shaft 330, the distance between the lower end of the link member 300 and the upper sidewall of the lower cover plate 200 is equal to the thickness of the link member 300, i.e., the distance between the lower side of the first link 310 and the upper sidewall of the lower cover plate 200 is equal to the height of the rotation shaft 330.

Optionally, a portion of the lower cover plate 200 located in the mounting port 110 is provided with a baffle 210, and the baffle 210 protrudes upward along an upper sidewall of the lower cover plate 200. In this way, since the distance between the lower side of the link member 300 and the lower side of the mounting port 110 in the vertical direction is relatively large, the baffle 210 protruding upward along the upper side wall thereof is provided at the portion of the lower cover plate 200 located in the mounting port 110, further shielding the lower region of the mounting port 110, thereby further reducing the dust inlet region of the mounting port 110 and reducing the risk of entry of impurities such as dust along the mounting port 110.

Optionally, both the upper cover plate 100 and the lower cover plate 200 are detachably connected to the upper sidewall of the case 400. In this way, the upper and lower cover plates 100 and 200 are easily installed and removed, and when the upper and lower cover plates 100 and 200 fail, the removal and maintenance can be efficiently performed.

For example, when the refrigerator hinge assembly is installed, the lower cover plate 200 is firstly installed on the upper side wall of the refrigerator body 400, the lower cover plate 200 is installed through structures such as screws and pins, then the connecting rod piece 300 is installed, the installed connecting rod piece 300 is partially located above the lower cover plate 200, finally the upper cover plate 100 is covered and installed on the upper side wall of the refrigerator body 400, the installation opening 110 of the front side wall of the upper cover plate 100 is clamped and installed at the front end of the lower cover plate 200, the lower cover plate 200 plays a role in positioning, and the upper cover plate 100 is installed through structures such as buckles and screws.

Alternatively, the link 300 is rotatably coupled to the door body 500 along an end of the mounting port 110. In this way, the end of the link member 300 extending along the mounting port 110 is rotatably coupled to the door body 500, so that the door body 500 can be rotated with respect to the link member 300, further increasing the opening width of the door body 500.

Specifically, the end of the second link 320 extending along the mounting port 110 is rotatably connected to the door body 500. Thus, since the first link 310 is positioned in the installation space 120, the end of the second link 320 opposite to the first link 310 is rotatably connected, and one end of the second link 320 protrudes along the installation opening 110, one end of the second link 320 is rotatably connected to the door body 500. Through the rotational connection of the first link 310 and the second link 320, the rotational connection of the second link 320 and the door body 500 enables the door body 500 to relatively rotate with the second link 320 while rotating with the second link 320, thereby further improving the opening width of the door body 500.

Illustratively, one end of the second link 320 is rotatably coupled to the door body 500 by a rotational coupling structure such as a hinge shaft.

Other embodiments may include structural and other modifications. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in, or substituted for, those of others.
