[0027] One embodiment of the present application provides a refrigerator, comprising a cabinet, a door body and a hinge assembly 100 connecting the cabinet and the door body. Specifically, one end of the hinge assembly 100 is arranged at the bottom of the cabinet, and the other end is arranged at the door body trim 300, thereby connecting the cabinet and the door body. It can be understood that the cooperation between the hinge assembly 100 and the door body is actually the cooperation between the hinge assembly 100 and the door body trim 300. In other embodiments, the hinge assembly 100 can directly cooperate with the door body or other parts of the door body, as long as it can drive the door body to move. Figures 1-4 As shown, it is a schematic view of the cooperation between the door body trim 300 and the hinge assembly 100 in one embodiment of the present application.

[0028] In a preferred embodiment, the hinge assembly 100 comprises a hinge bracket 10, a hinge shaft 30 and a cooperation part 50. The hinge bracket 10 is fixed to the cabinet, the hinge shaft 30 is rotationally matched with the hinge bracket 10 and is fixedly arranged in the vertical direction relative to the hinge bracket 10, and the cooperation part 50 is arranged on the door body and cooperates with the hinge shaft 30. One end of the hinge shaft 30 away from the door body is formed as an operation part 31, and the other end of the hinge shaft extends into the door body and is formed with a height adjustment part 33 which is threadedly matched with the cooperation part 50.

[0029] Rotating the operation part 31, since the hinge shaft 30 is fixed in the vertical direction relative to the hinge bracket 10, the hinge shaft 30 can only rotate in the hinge bracket 10, and the height adjustment part 33 is threadedly matched with the cooperation part 50, so that the rotational movement of the height adjustment part 33 is converted into the linear movement of the cooperation part 50, and the cooperation part 50 drives the door body trim 300 to move upward, thereby realizing the adjustment of the height of the door body. The hinge shaft 30 drives the cooperation part 50 to move through the height adjustment part 33 arranged at the upper end of the hinge shaft 30. During the adjustment process, the hinge shaft 30 does not move downward, does not occupy the space below the hinge bracket 10, and prevents scratching the floor.

[0030] In the preferred embodiment, the length of the height adjustment portion 33 in the vertical direction is greater than the length of the fitting portion 50, and during the height adjustment of the door body, the fitting portion 50 is located within the range of the height adjustment portion 33 in the vertical direction. As shown in Figs. 5-8, specifically, the height adjustment portion 33 has external threads arranged on the outer circumferential surface, and the fitting portion 50 has an internal thread structure. During the height adjustment, the internal threads of the fitting portion 50 are completely within the range of the external threads, and the number of engaged threads between the two is the total number of internal threads and remains unchanged, which helps the fitting portion 50 to maintain the maximum support force. It can be understood that the more the number of engaged threads between the two, the better the load-bearing capacity of the fitting portion 50. Therefore, by increasing the thickness of the fitting portion 50 in the vertical direction, i.e., increasing the number of engaged threads between the hinge shaft 30 and the fitting portion 50, the load-bearing capacity of the fitting portion 50 can be increased, and at the same time, the amount of shaking of the hinge shaft 30 can be controlled, and the risk of generating noise can be reduced.

[0031] In the preferred embodiment, the door body is provided with a sleeve portion 301 that at least partially accommodates the hinge shaft 30, and the fitting portion 50 is a thread structure formed on the inner wall surface of the sleeve portion 301, and the hinge shaft 30 is screwed into the fitting portion 50 from bottom to top. Specifically, the door body trim 301 is integrally formed with the sleeve portion 301, and the inner wall surface of the sleeve portion 301 is arranged as an internal thread structure at the corresponding height adjustment portion 33. In this way, there is no need to separately form the fitting portion 50, and the process flow is simplified.

[0032] In the preferred embodiment, the fitting portion 50 can also be a nut, which is embedded and formed in the sleeve portion 301, or installed in the sleeve portion 301 and fixed to the sleeve portion 301 by foaming. The fitting portion 50 and the sleeve portion 301 are fixed by assembly, which can reduce the process cost. The opening of the sleeve portion 301 is in a micro-flared structure, which facilitates the installation of the nut. The inner wall surface of the sleeve portion 301 at the position matched with the nut is arranged as a hexagonal shape, which can limit the rotation of the nut inside.

[0033] Specifically, the inner wall surface of the sleeve portion 301 is inwardly convexly provided with a convex wall 302, and the hinge shaft 30 is further provided with a blocking platform 32 located below the height adjustment portion 33 and protruding outwardly in the radial direction. When the door body is in the lowest position, the blocking platform 32 supports the convex wall 302, which can be used to support the weight of the door body, so that the weight of the door body is not only supported by the force of the threads, thereby prolonging the service life of the threads. In the specific embodiment, the fitting portion 50 is a nut and is installed into the sleeve portion 301 from top to bottom, and is installed above the convex wall 302.

[0034] The upper end of the hinge shaft 30 is formed as a height adjusting portion 33, the height adjusting portion 33 is screwed into the fitting portion 50 from bottom to top, and the resisting platform 32 can abut against the protruding wall 302. The resisting platform 32 protrudes outward to the inner wall surface of the sleeve portion 301, and supports the weight of the door body in a larger area. The resisting platform 32 is a circular platform adapted to the inner wall surface of the sleeve portion 301. The operation portion 31 is formed at the bottom end of the hinge shaft 30 and extends downward beyond the hinge frame 10, facilitating the operation of the customer. The operation portion 31 is in the shape of an outer hexagon, and the customer can rotate the operation portion 31 at the bottom by using a wrench to adjust the height of the door body.

[0035] In the preferred embodiment, the hinge assembly 100 comprises a first shaft sleeve 70 arranged in cooperation with the door body. The door body trim 300 is provided with a sleeve portion 301 for accommodating the hinge assembly. The inner wall surface of the sleeve portion 301 is provided with a vertical long groove 303. The outer peripheral surface of the first shaft sleeve 70 is provided with a vertical protruding rib 71, and the protruding rib 71 is located in the long groove 303. During the opening and closing of the door body of the refrigerator, the protruding rib 71 cooperates with the long groove 303, and the sleeve portion 301 rotates and drives the first shaft sleeve 70 to rotate relative to the hinge frame 10. The protruding rib 71 is clamped in the long groove 303 in the rotating direction, so as to ensure that the first shaft sleeve 70 does not rotate in the sleeve portion 301 during the opening and closing of the door body, but the first shaft sleeve 70 and the door body trim 300 rotate together relative to the hinge frame 10.

[0036] The cooperation of the protruding rib 71 and the long groove 303 also has a guiding effect. Specifically, when the first shaft sleeve 70 is installed in the sleeve portion 301 from bottom to top, the protruding rib 71 moves upward along the long groove 303 until the upper surface of the first shaft sleeve 70 abuts against the resisting platform 32 of the hinge shaft 30. During the upward movement of the door body, the long groove 303 moves upward along the protruding rib 71. Specifically, the long grooves 303 are uniformly and circumferentially arranged along the inner wall surface of the sleeve portion 301, and the protruding ribs 71 are uniformly and circumferentially arranged along the outer peripheral surface of the first shaft sleeve 70. The protruding rib 71 and the long groove 303 correspond to each other, and the length of the long groove 303 is slightly greater than the length of the protruding rib 71. The protruding rib 71 extends from the bottom to the middle position of the first shaft sleeve 70, so as to ensure that the long groove 303 does not move away from the protruding rib 71 during the upward movement of the door body, and to increase the clamping force of the protruding rib 71 and the long groove 303 in the rotating direction. The bottom of the first shaft sleeve 70 is provided with a bottom wall 72 protruding outward in the radial direction, the bottom wall 72 does not exceed the outer peripheral surface of the sleeve portion 301 in the radial direction, and the bottom of the sleeve portion 301 is located above the bottom wall 72.

[0037] In the preferred embodiment, the first shaft sleeve 70 abuts against the hinge bracket 10 downwardly, and the stop platform 32 abuts against the first shaft sleeve 70 downwardly. Specifically, the lower surface of the bottom wall 72 abuts against the hinge bracket 10, and the stop platform 32 abuts against the upper surface of the first shaft sleeve 70 downwardly. In this way, the stop platform 32 transmits the weight of the door body to the hinge bracket 10 by abutting against the first shaft sleeve 70.

[0038] In the preferred embodiment, the first shaft sleeve 70 can be mounted in the sleeve portion 301 from bottom to top first, and then the hinge bracket 10 is mounted into the first shaft sleeve 70 from bottom to top; or, the first shaft sleeve 70 is movably sleeved on the hinge bracket 10, and then the first shaft sleeve 70 and the hinge bracket 10 are mounted in the sleeve portion 301 from bottom to top together.

[0039] In the preferred embodiment, the hinge bracket 10 comprises a base 11 connected to the cabinet and a second shaft sleeve 13 fixed to the base 11. The second shaft sleeve 13 is arranged in alignment with the first shaft sleeve 70 in the vertical direction. The first shaft sleeve 70 is provided with a first cam surface 721 facing the second shaft sleeve 13. The second shaft sleeve 13 is provided with a second cam surface 131 facing the first shaft sleeve 70. The first cam surface 721 and the second cam surface 131 are in contact with each other. The first cam surface 721 is the lower surface of the bottom wall 72, and the second cam surface is part of the upper surface of the second shaft sleeve 13. The first cam surface 721 and the second cam surface 131 are arranged unevenly. The high part of the first cam surface 721 corresponds to the low part of the second cam surface 131, and the low part of the first cam surface 721 corresponds to the high part of the second cam surface 131. The two are in contact with each other to control the opening and closing angle of the door body.

[0040] In the preferred embodiment, the hinge bracket 10 further comprises a sleeve 15 arranged on the base 11. The hinge shaft 30 passes through the sleeve 15 and is in rotational cooperation with the sleeve 15. The second shaft sleeve 13 is arranged on the outer periphery of the sleeve. Specifically, the hinge shaft 30 passes through the sleeve 15 at the lower part of the height adjustment portion 33 and is exposed below the base 11 to form the operation portion 31. The stop platform 32 abuts against the upper surface of the first shaft sleeve 70 downwardly. The sleeve 15 extends upwardly to the upper surface of the first shaft sleeve 70. The sleeve 15 is fixed to the base 11 downwardly. The second shaft sleeve 13 is a sheet-shaped body provided with a circular hole 130. The second shaft sleeve 13 is sleeved on the sleeve 15 and is attached to the upper surface of the base 11. The second shaft sleeve 13 is provided with the second cam surface 131 at the position corresponding to the circular hole 130.

[0041] More specifically, the sleeve 15 and the base 11 are generally iron pieces, the sleeve 15 is assembled with the base 11 by welding or riveting process; if the sleeve 15 is a high-strength plastic piece, the sleeve 15 and the base 11 are fixed together by screwing or other methods. The second shaft sleeve 13 is a high-strength plastic piece, which is fixed on the outer diameter of the sleeve 15, and the second shaft sleeve 13 is fixed on the base 11 by screwing, and the second shaft sleeve 13 does not move during the rotation of the door body. If the sleeve 15 and the second shaft sleeve 13 are plastic pieces, they can be integrally formed as one piece.

[0042] In summary, the sleeve 15 is assembled and fixed on the base 11, and the second shaft sleeve 13 is sleeved on the sleeve 15 and assembled and fixed on the base 11; or the sleeve 15 and the base 11 are integrally formed, and the second shaft sleeve 13 is assembled and fixed on the base 11; or the sleeve 15 and the second shaft sleeve 13 are integrally formed and then assembled and fixed on the base 11; the hinge bracket 10 can be formed by any of the above methods.

[0043] The assembly process and the adjustment process of the present application are briefly described below. The door body trim 300 can directly form a threaded matching part 50, or the matching part 50 is fixed in the door body trim 300 by a nut, and then the hinge shaft 30 is installed into the sleeve part 301 from bottom to top and is screwed with the matching part 50; next, the first shaft sleeve 70 can be assembled into the sleeve part 301 first, and then installed into the hinge bracket 10, or the first shaft sleeve 70 can be sleeved on the hinge bracket 10 first, and then installed together in the sleeve part 301.

[0044] During adjustment, the operating part 31 at the bottom of the hinge assembly 100 is rotated by a wrench, the resisting platform 32 of the hinge shaft 30 downwardly abuts against the first shaft sleeve 70 so as to be unable to move downwardly, and the height adjustment part 33 at the upper end of the hinge shaft 30 is screwed with the matching part 50, so that the matching part 50 moves upwardly, the door body trim 300 moves upwardly, and the purpose of adjusting the height of the door body is achieved. Figures 7-8 It can be seen that after adjustment, the protruding wall 302 of the door body will be displaced upwardly to form a gap with the resisting platform 32, and the resisting platform 32 will still downwardly abut against the first shaft sleeve 70, so as to transmit the weight of the door body to the hinge bracket 10. Before adjustment, the distance between the door body trim 300 and the base 11 is a, and after adjustment, the door body trim 300 moves upwardly by a distance, the distance between the door body trim 300 and the base 11 becomes b, and the hinge shaft 30 and the hinge bracket 10 do not change in displacement along the vertical direction, so that no matter what height the door body is adjusted to, the size of the hinge shaft 30 from the ground does not change, and the problem of scratching the floor does not occur.

[0045] The beneficial effects of the present application are that the hinge shaft 30 drives the matching part 50 to move through the height adjusting part 33 arranged at the upper end of the hinge shaft 30, and during the adjusting process, the hinge shaft 30 does not move downward, does not occupy the space below the hinge frame 10, and prevents scratching the floor; when the door body is at the lowest position, the resisting platform 32 abuts against the protruding wall 302, which can support the weight of the door body; the resisting platform 32 can transmit the weight of the door body to the hinge frame 10 through the first shaft sleeve 70; the protruding ribs 71 and the long groove 303 not only can limit the rotation but also have a guiding effect.

[0046] It should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
