Description

Technical Field

[0001] This disclosure relates to the field of refrigeration equipment technology, and specifically to a refrigeration equipment. Background Technology

[0002] Most household appliances use hinges to achieve the rotational connection between the door and the cabinet. For example, an increasing number of high-end refrigerators use multi-axis hinges to achieve zero-distance embedding, allowing the door to open and close normally while ensuring that the gap between the refrigerator and the built-in cabinet is less than 4 millimeters.

[0003] Most refrigeration appliances on the market today typically have multiple doors, such as French door refrigerators and cross-door refrigerators. During the manufacturing process, each door is hinged to the cabinet before the appliance is shipped as a whole. However, during transportation, the doors may sag or tilt, and the amount of displacement may vary between the doors. This can lead to misalignment of the doors when the appliance is delivered and installed in the customer's home, affecting the overall aesthetics of the appliance. Utility Model Content

[0004] One object of the embodiments of this disclosure is to provide an improved refrigeration appliance.

[0005] Therefore, this disclosure provides a refrigeration appliance including a housing and a door. The housing defines at least one storage compartment. The door is movably connected to the front of the housing via a hinge to open or close at least a portion of the storage compartment. The hinge includes a first end connected to the door and a second end connected to the housing. The appliance also includes a first adjustment mechanism and / or a second adjustment mechanism. The first adjustment mechanism includes a first adjustment plate and a first eccentric adjustment member. The first adjustment plate is fixed to the door and has a first oblique hole. The first eccentric adjustment member includes a first pivot portion rotatably connected to the first end and a first eccentric portion located in the first oblique hole. The first pivot portion rotates... When the first eccentric part acts on the inner wall of the first waist hole, the first end and the first adjusting plate will have a relative displacement in the first direction; the second adjusting mechanism includes a second adjusting plate and a second eccentric adjusting member. The second adjusting plate is fixed to the box body and has a second waist hole. The second eccentric adjusting member includes a second rotating shaft part rotatably connected to the second end and a second eccentric part located in the second waist hole. When the second rotating shaft part rotates, the second eccentric part acts on the inner wall of the second waist hole, so that the second end and the second adjusting plate will have a relative displacement in the second direction; wherein, one of the first direction and the second direction is a horizontal direction, and the other is a vertical direction.

[0006] This implementation scheme allows for the adjustment of the door's position relative to the hinge and / or the hinge's position relative to the cabinet, thereby achieving door position adjustment. Taking a refrigeration appliance with a cross door as an example, the door's position can be finely adjusted through the first and / or second adjustment mechanisms to ensure that the vertical and / or horizontal gaps between adjacent doors of the cross door remain consistent, improving the visual appearance of the refrigeration appliance.

[0007] The second eccentric part and the second waist hole cooperate at the second adjusting plate to achieve vertical or horizontal adjustment. Since the second adjusting plate with the second waist hole is fixed to the cabinet, the second end of the hinge only needs to have a through hole for the second eccentric part to pass through. Thus, the through hole in the hinge can play a positioning role. The second eccentric adjusting part passes through the second waist hole and the through hole in sequence to position the relative position of the hinge and the cabinet, avoiding positioning deviations of the hinge relative to the cabinet during installation, which would affect the overall appearance of the refrigeration appliance when it leaves the factory.

[0008] Furthermore, the first and second adjustment mechanisms are located at both ends of the hinge, resulting in a simple structure that does not interfere with each other.

[0009] Optionally, the first eccentric adjustment member is riveted to the first end. Thus, the first eccentric adjustment member is riveted to the hinge to achieve connection and positioning, preventing the first eccentric adjustment member from unexpectedly falling off during transportation and daily use of the refrigeration appliance. Furthermore, the adjustment portion of the first eccentric adjustment member, i.e., the first eccentric part, rotates within the first oblique hole of the first adjustment plate for adjustment. Therefore, the first eccentric adjustment member and different components cooperate to perform connection positioning and relative position adjustment respectively, which helps to distribute the force and prevents the connection positioning and adjustment functions from failing simultaneously due to damage to a single component.

[0010] Optionally, the second eccentric adjustment member is riveted to the second end. Thus, the second eccentric adjustment member is riveted to the hinge to achieve connection positioning, preventing the second eccentric adjustment member from unexpectedly falling off during transportation and daily use of the refrigeration appliance. Furthermore, the adjusting portion of the second eccentric adjustment member, i.e., the second eccentric part, rotates within the second oblique hole of the second adjusting plate for adjustment. Therefore, the second eccentric adjustment member and different components cooperate to perform connection positioning and relative position adjustment respectively, which helps to distribute the force and prevents the connection positioning and adjustment functions from failing simultaneously due to damage to a single component.

[0011] Optionally, the first adjustment mechanism further includes a first shim, sandwiched between the head and the first end of the first eccentric adjustment member. This ensures a reliable connection between the hinge and the first eccentric adjustment member while allowing the first eccentric adjustment member to rotate relatively smoothly relative to the hinge.

[0012] Optionally, the second adjustment mechanism further includes a second shim, sandwiched between the head and the second end of the second eccentric adjustment member. This ensures a reliable connection between the hinge and the second eccentric adjustment member while allowing the second eccentric adjustment member to rotate relatively smoothly relative to the hinge.

[0013] Optionally, the first waist hole extends along the second direction, the first adjusting plate is provided with a first guide portion extending along the first direction, and the first end is provided with a first adapter portion extending along the first direction. During the period when the first eccentric portion acts on different positions of the inner wall of the first waist hole as the first rotating shaft portion rotates, the first guide portion and the first adapter portion cooperate to guide the first adjusting plate to move relative to the first end along the first direction. The cooperation of the guide rib and guide groove guides and restricts the movement of the hinge and the first adjusting plate along the first direction, ensuring precise adjustment of the door along the first direction.

[0014] Optionally, the first end and the first adjusting plate are connected by a first fastener. The first end has a first fixing hole, and the first adjusting plate has a first adapter hole. The first fastener passes through the first fixing hole and the first adapter hole in sequence and is riveted to the first end. The hinge and the first adjusting plate are connected together by the first fastener, ensuring the reliability of the connection between the hinge and the first adjusting plate.

[0015] Optionally, the first fixing hole is an elongated hole, and the first adapter hole is a circular hole. As the first rotating shaft of the first eccentric adjusting member rotates within the first circular hole, the eccentric position of the first eccentric part acts on the inner wall of the first oblong hole, achieving relative displacement between the hinge and the first adjusting plate. During the relative displacement, the first fixing member moves within the first fixing hole along with the movement of the first adjusting plate. Thus, the first fixing hole can also serve as a guide, ensuring the overall stability of the relative displacement between the hinge and the first adjusting plate.

[0016] Optionally, the first adjusting plate is fixed to the door by a second fixing member. The first end of the first fixing plate has a second fixing hole through which the second fixing member passes. This second fixing hole is an elongated hole. Thus, the second fixing member passes sequentially through the second fixing hole, the first adjusting plate, and the door to fix the first adjusting plate and the door. During the relative displacement between the hinge and the first adjusting plate, the second fixing member moves within the second fixing hole along with the movement of the first adjusting plate. Therefore, the second fixing hole also serves as a guide, ensuring the overall stability of the relative displacement between the hinge and the first adjusting plate.

[0017] Optionally, the second waist hole extends along the first direction, and a guide mechanism is provided at the second end. The guide mechanism is used to guide the second end to move relative to the second adjusting plate along the second direction during different positions of the second eccentric portion acting on the inner wall of the second waist hole as the second rotating shaft portion rotates. This ensures that the door is precisely adjusted along the second direction.

[0018] Optionally, the second end and the housing are fixed together by a third fastener. The second end has a third fixing hole through which the third fastener passes. The third fixing hole is an elongated hole extending along the second direction to form the guide mechanism. Thus, the guide mechanism is formed by reusing the fixing structure of the hinge and the housing, reducing the structural complexity of the hinge and without increasing the hinge thickness.

[0019] Optionally, the second adjusting plate has a third adapter hole for receiving the third fixing member, the third adapter hole being a threaded hole. Thus, the hinge, the second adjusting plate, and the housing are connected together via the third fixing member.

[0020] Optionally, the housing includes a crossbeam forming at least a portion of the front surface of the housing, along the depth direction of the refrigeration appliance. The second adjusting plate and the hinge are located on opposite sides of the crossbeam, and the crossbeam has a third waist hole corresponding to the second waist hole. Thus, without increasing the hinge thickness, the refrigeration appliance of this embodiment can use a thinner door.

[0021] Optionally, the door includes a first door and a second door arranged side-by-side along the width direction of the refrigeration appliance. The second adjusting plate has two second oblique holes arranged side-by-side along the second direction. One of the two second oblique holes is used for the first door, and the other of the two second oblique holes is used for the second door. Thus, the same second adjusting plate can be compatiblely installed on the left or right side of the cabinet, reducing the number of molds required.

[0022] Optionally, the doors include a first door and a third door arranged side-by-side along the height direction of the refrigeration appliance. The second adjusting plate has two second oblique holes arranged side-by-side along the first direction, one of which is used for the first door, and the other for the third door. Thus, a single second adjusting plate can be reused to support the relative position adjustment of multiple doors and the cabinet, reducing the number of parts.

[0023] Optionally, the head of the first eccentric adjustment member is flush with the surface of the first end facing away from the first adjustment plate. This allows for a larger internal space in the hinge to accommodate the hinge's own structure and also facilitates the miniaturization of the hinge design.

[0024] Optionally, the distance by which the head of the first eccentric adjustment member extends beyond the surface of the first end opposite to the first adjustment plate is less than or equal to 2 mm. Therefore, the first eccentric adjustment member does not occupy excessive internal space of the hinge, which is beneficial for the miniaturization of the hinge design.

[0025] Optionally, the length of the straight segment of the first waist hole is taken from [1.5, 3] mm.

[0026] Optionally, the length of the straight segment of the second waist hole is taken from [1.5, 3] mm.

[0027] Optionally, the first end has a first circular hole for accommodating the first rotating shaft. As the first rotating shaft rotates around its fixed axis within the first circular hole, the first eccentric part rotates within the first waist hole so that the eccentric position acts on different positions on the inner wall of the first waist hole, thereby realizing the relative displacement of the hinge and the first adjusting plate.

[0028] Optionally, the second end is provided with a second circular hole for accommodating the second rotating shaft. As the second rotating shaft rotates around its fixed axis within the second circular hole, the second eccentric part rotates within the second waist hole so that the eccentric position acts on different positions on the inner wall of the second waist hole, thereby realizing the relative displacement of the hinge and the second adjusting plate.

[0029] Optionally, the first direction is a vertical direction, and the second direction is a horizontal direction. Thus, the door can be adjusted vertically at the first end and horizontally at the second end. Attached Figure Description

Detailed Implementation

[0043] To make the above-mentioned objects, features and advantages of this disclosure more apparent and understandable, specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0044] Figure 1 This is a schematic diagram of a refrigeration appliance 1 according to an embodiment of the present disclosure. Figure 2 yes Figure 1 A magnified view of a portion of region A in the middle.

[0045] The refrigeration appliance 1 can be, for example, a refrigerator, a freezer, a wine cabinet, etc. For ease of description, in this embodiment, the width direction of the refrigeration appliance 1 is denoted as the x-direction, the depth direction as the y-direction, and the height direction as the z-direction. In this embodiment, the front-back direction refers to the y-direction and its opposite direction. Specifically, "front" or "front side" refers to the direction in which the refrigeration appliance 1 faces the user when in use, and "rear" or "rear side" refers to the direction in which the refrigeration appliance 1 is away from the user when in use.

[0046] Specifically, refer to Figure 1 and Figure 2 The refrigeration appliance 1 may include a housing 10 and a door 11, the housing 10 defining at least one storage compartment 101, and the door 11 being movably connected to the front of the housing 10 via a hinge 2 to open or close at least a portion of the storage compartment 101. Figure 1 Taking a cross-door refrigerator as an example, the refrigerator includes four doors 11 arranged side-by-side along the x and z directions. For ease of description, the four doors 11 are referred to as the first door 115, the second door 116, the third door 117, and the fourth door 118. The first door 115 and the second door 116 are arranged side-by-side along the x direction, the third door 117 and the fourth door 118 are arranged side-by-side along the x direction, the first door 115 and the third door 117 are arranged side-by-side along the z direction, and the second door 116 and the fourth door 118 are arranged side-by-side along the z direction. Each door 11 is connected to the cabinet body 10 by two hinges 2 spaced apart along the z direction. Figure 2 An illustrative example shows the connection between the first door 115 and the housing 10 via the upper hinge. Figure 10 An exemplary illustration shows the connection between the first door 115 and the housing 10 via a lower hinge and the third door 117 via an upper hinge. Both the upper and lower hinges can be hinges 2 with the same structure.

[0047] Furthermore, the hinge 2 may include a first end 2a connected to the door 11 and a second end 2b connected to the cabinet 10. In the scenario where the refrigeration appliance 1 is embedded, the hinge 2 can be a multi-axis hinge. During the opening process, in addition to rotating relative to the cabinet 10 around the hinge 2, the door 11 also moves as a whole in the x direction to reduce the extent to which the outer edge of the door 11 extends beyond the side wall of the cabinet 10 when the door 11 is in the open position, thus preventing the door 11 from hitting the side wall of the embedded cabinet when opening and closing. For example, the hinge 2 can be a six-link connection structure, including a first link 21, a second link, a third link, a fourth link, a fifth link, and a sixth link 22. The first link 21 is adapted to form the second end 2b and connect to the cabinet 10, and the sixth link 22 is adapted to form the first end 2a and connect to the door 11. The second to fifth links are interconnected to form a link body 23. The two ends of the link body 23 are respectively hinged to the first link 21 and the sixth link 22, and the opening and closing of the door 11 is driven by the movement of each link. For example, refer to Figures 2 to 4 The sixth link 22 may have a second mounting hole 225 for the second connector 226 to pass through in order to rotatably connect the sixth link 22 and the link body 23 together.

[0048] Further reference Figures 1 to 8 The refrigeration appliance 1 may further include a first adjusting mechanism 3 and / or a second adjusting mechanism 4, wherein the first adjusting mechanism 3 is used to adjust the relative position of the door 11 and the cabinet 10 along a first direction u, and the second adjusting mechanism 4 is used to adjust the relative position of the door 11 and the cabinet 10 along a second direction v. For example, the refrigeration appliance 1 may be equipped with both the first adjusting mechanism 3 and the second adjusting mechanism 4 to achieve position adjustment of the door 11 in two dimensions. Alternatively, the refrigeration appliance 1 may be equipped with only the first adjusting mechanism 3 or only the second adjusting mechanism 4 to achieve position adjustment of the door 11 in a single dimension.

[0049] One of the first direction u and the second direction v is the transverse direction (also called the horizontal direction), and the other is the vertical direction. The vertical direction can be parallel to the z-direction. The transverse direction can be perpendicular to the z-direction. For example, in door 11... Figure 1 When the closed position is shown, the lateral direction is parallel to the x-direction. Next, this implementation scheme will be described in detail using the first direction u as the vertical direction and the second direction v as the lateral direction as an example.

[0050] Still with Figure 1Taking the cross-door refrigerator shown as an example, there is a vertical gap between the first door 115 and the second door 116 (denoted as the first gap 111), a vertical gap between the third door 117 and the fourth door 118 (denoted as the second gap 112), a horizontal gap between the first door 115 and the third door 117 (denoted as the third gap 113), and a horizontal gap between the second door 116 and the fourth door 118 (denoted as the fourth gap 114). Before the refrigerator 1 leaves the factory, the four doors 11 are pre-installed on the cabinet 10. At the time of manufacture, the first gap 111 and the second gap 112 are aligned, and the third gap 113 and the fourth gap 114 are aligned. However, due to factors such as transportation bumps and accidental collisions, after the refrigerator 1 is delivered to the user, the first gap 111 and the second gap 112 may be misaligned, the third gap 113 and the fourth gap 114 may be misaligned, and the gap width may be uneven, which will greatly reduce the appearance of the refrigerator 1. This implementation scheme achieves position adjustment of the door 11 by setting a first adjustment mechanism 3 and / or a second adjustment mechanism 4 at the hinge 2, so that the refrigeration appliance 1 can correct the aforementioned misalignment after being transported to the user, and can keep the first gap 111 and the second gap 112 aligned, and the third gap 113 and the fourth gap 114 aligned during daily use of the refrigeration appliance 1.

[0051] For example, Figure 1 In the four doors 11 of the shown cross-door refrigerator, each door 11 can be equipped with a first adjustment mechanism 3 and a second adjustment mechanism 4 on its upper and lower hinges. Assuming that the first gap 111 and the second gap 112 are misaligned, or that the width of a single gap varies significantly at different positions along the z-direction, the second adjustment mechanism 4 of one or more doors 11 can be operated to adjust the size and relative position of the first gap 111 and / or the second gap 112 until the two gaps are substantially aligned along the z-direction and the width of each gap along the z-direction is substantially consistent. Similarly, assuming that the width of the third gap 113 and the fourth gap 114, or a single gap, varies significantly at different positions along the x-direction, the first adjustment mechanism 3 of one or more doors 11 can be operated to adjust the size and relative position of the third gap 113 and / or the fourth gap 114 until the two gaps are substantially aligned along the x-direction and the width of each gap along the x-direction is substantially consistent.

[0052] Therefore, by adopting this embodiment, the position of door 11 relative to hinge 2 and / or the position of hinge 2 relative to housing 10 can be adjusted as needed, thereby achieving the adjustment of the position of door 11. Taking the refrigeration appliance 1 as a cross door as an example, the position of door 11 can be finely adjusted by the first adjustment mechanism 3 and / or the second adjustment mechanism 4 to ensure that the vertical gap and / or horizontal gap between two adjacent doors 11 of the cross door are consistent, thereby improving the visual appearance of the refrigeration appliance 1.

[0053] In a specific implementation, refer to Figures 1 to 4 , Figure 7 The first adjustment mechanism 3 may include a first adjustment plate 31, which is fixed to the door 11. For example, the first adjustment plate 31 may have multiple first mounting holes 15, and the first connecting member 151 fixes the first adjustment plate 31 to the end cover of the door 11 through the first mounting holes 15. In other words, the first adjustment plate 31 and the door 11 are fixedly connected and move synchronously.

[0054] Furthermore, the first adjusting plate 31 may have a first waist hole 311. The first waist hole 311 may include a connected straight line segment and an arc segment located at at least one end of the straight line segment. The extension direction of the straight line segment may be determined according to a first direction u.

[0055] Furthermore, the first adjusting mechanism 3 may also include a first eccentric adjusting member 32, specifically comprising a first rotating shaft portion 321 rotatably connected to the first end 2a and a first eccentric portion 322 located in the first waist hole 311. For example, along the axial direction of the first rotating shaft portion 321, the first eccentric adjusting member 32 sequentially includes a head 323, the first rotating shaft portion 321, and the first eccentric portion 322. The first eccentric portion 322 is eccentric relative to the first rotating shaft portion 321; for example, both the first eccentric portion 322 and the first rotating shaft portion 321 are cylinders and their axes are not collinear. (Reference) Figure 3 , Figure 7 and Figure 9 After assembly, the first eccentric part 322 is located in the first waist hole 311, the first rotating shaft part 321 is accommodated in the first round hole 224 opened in the first end 2a (e.g., the sixth link 22), and the head 323 of the first eccentric adjusting member 32 is located on the side of the sixth link 22 away from the first adjusting plate 31.

[0056] When the first rotating shaft 321 rotates, the first eccentric part 322 acts on the inner wall of the first waist hole 311, causing the first end 2a and the first adjusting plate 31 to have a relative displacement in the first direction u. For example, the head 323 of the first eccentric adjusting member 32 can be provided with a mating groove. After the installer uses a suitable tool to insert into the mating groove, the tool can be rotated synchronously to rotate the first eccentric adjusting member 32. As the first rotating shaft 321 rotates on a fixed axis in the first circular hole 224, the first eccentric part 322 rotates in the first waist hole 311 so that the eccentric position acts on different positions of the inner wall of the first waist hole 311, realizing the relative displacement between the hinge 2 and the first adjusting plate 31. In the scenario where the first direction u is vertical, the door 11 can be adjusted up and down at the first end 2a, that is, the door 11 can move up and down relative to the sixth link 22 along the z direction with the first adjusting plate 31.

[0057] In some embodiments, the length of the straight segment of the first waist hole 311 can be taken from [1.5, 3] mm. For example, the length of the straight segment of the first waist hole 311 can be 2 mm, and correspondingly, the maximum distance that the door 11 can be adjusted along the first direction u is 2 mm.

[0058] In one specific implementation, the first eccentric adjustment member 32 can be riveted to the first end 2a. Specifically, after the first eccentric adjustment member 32 is installed onto the sixth link 22 and the first adjusting plate 31, the head 323 of the first eccentric adjustment member 32 can be pressed tightly with a tool. The pressed head 323 of the first eccentric adjustment member 32 can form a flange around the first circular hole 224, thereby riveting the first eccentric adjustment member 32 to the sixth link 22.

[0059] Furthermore, the flange can cover the surface 22a of the first end 2a that is away from the first adjusting plate 31.

[0060] Furthermore, the riveting between the first eccentric adjusting member 32 and the sixth connecting rod 22 can be a rotary riveting.

[0061] Therefore, the first eccentric adjustment member 32 is riveted to the hinge 2 to achieve connection and positioning, preventing the first eccentric adjustment member 32 from unexpectedly falling off during transportation and daily use of the refrigeration appliance 1. Furthermore, the adjustment part of the first eccentric adjustment member 32, namely the first eccentric part 322, rotates within the first waist hole 311 of the first adjustment plate 31 for adjustment. Thus, the first eccentric adjustment member 32 cooperates with different components to perform connection positioning and relative position adjustment respectively, which helps to distribute the force and avoid the failure of connection positioning and adjustment functions due to damage to a single component.

[0062] In a specific implementation, refer to Figures 2 to 4 The first adjustment mechanism 3 may further include a first shim 33, which is sandwiched between the head 323 and the first end 2a of the first eccentric adjustment member 32. For example, the first shim 33 may be sandwiched between the head 323 and the surface 22a of the first end 2a that is away from the first adjustment plate 31.

[0063] The first gasket 33 can be made of a material with a low coefficient of friction. For example, the first gasket 33 can be made of a metal.

[0064] Therefore, while ensuring a reliable connection between the hinge 2 and the first eccentric adjustment member 32, it is also ensured that the first eccentric adjustment member 32 can rotate relatively smoothly relative to the hinge 2.

[0065] In a specific implementation, continue to refer to Figure 4 The first waist hole 311 can extend along the second direction v, that is, the straight segment of the first waist hole 311 can extend along a direction perpendicular to the first direction u.

[0066] Furthermore, the first adjusting plate 31 may be provided with a first guide portion 312 extending along the first direction u, and the first end 2a may be provided with a first adapter portion 221 extending along the first direction u. During the period when the first eccentric portion 322 acts on the inner wall of the first waist hole 311 as the first rotating shaft portion 321 rotates, the first guide portion 312 and the first adapter portion 221 cooperate to guide the first adjusting plate 31 to move relative to the first end 2a along the first direction u.

[0067] For example, if the first direction u is vertical, then the first waist hole 311 on the first adjusting plate 31 is a horizontal waist hole, and the through hole on the sixth connecting rod 22 is a round hole (i.e., the first round hole 224). The first eccentric adjusting member 32 is riveted to the sixth connecting rod 22, and the first eccentric part 322 is inserted into the horizontal waist hole of the first adjusting plate 31. Two vertically extending guide ribs are provided on the first adjusting plate 31 as the first guide part 312, which cooperate with the two guide grooves (i.e., the first adapter part 221) on the sixth connecting rod 22 to guide the sixth connecting rod 22 and the first adjusting plate 31 to only have relative movement in the vertical direction. The two guide ribs can be provided on both sides of the first waist hole 311 along the extending direction, and correspondingly, the two guide grooves can also be located on both sides of the first round hole 224.

[0068] During operation of the first eccentric adjustment member 32, the sixth link 22 remains stationary, while the first adjustment plate 31, under the action of the first eccentric part 322 and guided by the cooperation of the first adapter part 221 and the first guide part 312, moves up and down relative to the sixth link 22 along the first direction u. Thus, by guiding and restricting the movement of the hinge 2 and the first adjustment plate 31 along the first direction u through the cooperation of the guide rib and guide groove, the door 11 is ensured to be precisely adjusted along the first direction u.

[0069] In a specific implementation, continue to refer to Figures 2 to 4 , Figure 7 and Figure 9 The first end 2a and the first adjusting plate 31 can be connected by the first fastener 12. For example, the first fastener 12 can be a rivet.

[0070] Specifically, the first end 2a (e.g., the sixth link 22) may have a first fixing hole 222, and the first adjusting plate 31 may have a first adapter hole 313. For example, along the extension direction of the first waist hole 311, the first adapter hole 313 may be provided at both ends of the first adjusting plate 31, and correspondingly, the first fixing hole 222 may be provided at both ends of the sixth link 22, and the number of the first fixing members 12 is also two.

[0071] Furthermore, the first fixing member 12 passes through the first fixing hole 222 and the first adapter hole 313 in sequence and is riveted to the first end 2a. The first fixing member 12 can be riveted to the side of the sixth link 22 opposite to the first adjusting plate 31.

[0072] Thus, the hinge 2 and the first adjusting plate 31 are connected together by the first fixing member 12, ensuring the reliability of the connection between the hinge 2 and the first adjusting plate 31.

[0073] In some embodiments, the first fixing hole 222 can be an elongated hole. For example, the length direction of the elongated hole is parallel to the first direction u. For example, the first fixing hole 222 can be a long slotted hole extending vertically. The relative positions of the first fixing member 12 and the sixth connecting rod 22 along the first direction u are variable.

[0074] The first adapter hole 313 is a circular hole. The diameter of the circular hole can be approximately equal to the diameter of the shaft portion of the first fixing member 12. The relative positions of the first fixing member 12 and the first adjusting plate 31 are fixed.

[0075] As the first eccentric adjusting member 32 rotates within the first circular hole 224, the eccentric position of the first eccentric part 322 acts on the inner wall of the first waist hole 311, thereby achieving relative displacement between the hinge 2 and the first adjusting plate 31. During the relative displacement, the first fixing member 12 moves within the first fixing hole 222 along with the movement of the first adjusting plate 31. Thus, the first fixing hole 222 can also serve as a guide, ensuring the overall stability of the relative displacement between the hinge 2 and the first adjusting plate 31.

[0076] In some embodiments, when the refrigeration appliance 1 is manufactured, the first fixing member 12 can be positioned at the middle position of the first fixing hole 222. Accordingly, when the first eccentric adjustment member 32 is rotated, the door 11 and the hinge 2 have two relative displacement degrees of freedom in the first direction u. For example, if the first direction u is the vertical direction, then as the first eccentric adjustment member 32 rotates clockwise or counterclockwise, the door 11 can move up and down relative to the hinge 2.

[0077] In one variation, when the refrigeration appliance 1 is manufactured, the first fixing member 12 can be positioned at one end of the first fixing hole 222. Accordingly, when the first eccentric adjustment member 32 is rotated, the door 11 and the hinge 2 have a single degree of relative displacement freedom in the first direction u. For example, if the first direction u is vertical, and the first fixing member 12 is positioned at the upper (or lower) end of the first fixing hole 222 along its length when the refrigeration appliance 1 is manufactured, the door 11 is in the adjustable highest (or lowest) position. As the first eccentric adjustment member 32 rotates clockwise (or counterclockwise), the door 11 can move downward (or upward) relative to the hinge 2.

[0078] In a specific implementation, continue to refer to Figures 2 to 4 The first adjusting plate 31 and the door 11 can be fixed together by the second fixing member 13. For example, the second fixing member 13 can be a screw, and the first adjusting plate 31 and the door 11 are connected by threads through the second fixing member 13.

[0079] Specifically, the first adjusting plate 31 may have a second adapter hole 314 for the second fixing member 13 to pass through. The second adapter hole 314 may be a circular hole. The diameter of the circular hole may be approximately equal to the diameter of the screw. The relative positions of the second fixing member 13 and the first adjusting plate 31 are fixed.

[0080] Furthermore, the first end 2a (e.g., the sixth link 22) may have a second fixing hole 223 through which the second fixing member 13 passes. The second fixing hole 223 may be an elongated hole. For example, the length direction of the elongated hole is parallel to the first direction u, that is, the second fixing hole 223 may be a vertically oriented elongated hole. The relative positions of the second fixing member 13 and the sixth link 22 along the first direction u are variable.

[0081] The second fixing member 13 passes sequentially through the second fixing hole 223, the second adapter hole 314 opened in the first adjusting plate 31, and the door 11 to fix the first adjusting plate 31 and the door 11. Furthermore, during the relative displacement of the hinge 2 and the first adjusting plate 31, the second fixing member 13 moves within the second fixing hole 223 as the first adjusting plate 31 moves. Thus, the second fixing hole 223 can also play a guiding role, ensuring the overall stability of the relative displacement of the hinge 2 and the first adjusting plate 31.

[0082] In some embodiments, when the refrigeration appliance 1 leaves the factory, the second fixing member 13 can be tightened to reliably connect the door 11, the first adjusting plate 31, and the sixth link 22 together. When it is necessary to operate the first eccentric adjusting member 32 to adjust the position of the door 11, the second fixing member 13 is loosened to facilitate the movement of the first adjusting plate 31 relative to the sixth link 22. After the position adjustment of the door 11 along the first direction u is completed, the second fixing member 13 is tightened again to secure the door 11 and the first adjusting plate 31.

[0083] Regarding the positioning position of the second fixing member 13 in the second fixing hole 223 when the refrigeration appliance 1 leaves the factory, please refer to the aforementioned description of the positioning position of the first fixing member 12 in the first fixing hole 222.

[0084] In some embodiments, a first waist hole 311 may be provided at the middle of the first adjusting plate 31 along its length direction (e.g., horizontal direction). On both sides of the first waist hole 311 along its length direction, a second adapter hole 314 and a first adapter hole 313 are sequentially provided from the middle to both ends. Correspondingly, a first circular hole 224 is located at the middle of the sixth connecting rod 22 along its length direction, with a second fixing hole 223 and a first fixing hole 222 sequentially provided on both sides. Thus, reliable positioning and connection of the first adjusting member 31 and the sixth connecting rod 22 are achieved throughout the entire length direction.

[0085] In some embodiments, after the connecting rod body 23 is installed onto the sixth connecting rod 22, the second fixing hole 223 closer to the connecting rod body 23 is covered by the connecting rod body 23, which may hinder the installation of the second fixing member 13. In this example, the sixth connecting rod 22 may further have a first hole 16, which directly or indirectly connects to the second fixing hole 223 and has a larger diameter. Similarly, the first adjusting plate 31 may also have a first hole 16 with a larger diameter and directly or indirectly connect to the second adapter hole 314. The second fixing member 13 can be tightened after entering the second fixing hole 223 and the second adapter hole 314 through the first hole 16 to complete the connection between the door 11 and the first adjusting plate 31.

[0086] In some embodiments, continue to refer to Figures 2 to 4 The sixth link 22 may include a base plate and a pair of wing plates extending laterally from both sides of the base plate in the vertical direction. The base plate and the pair of wing plates together form a receiving space that opens to one side to receive at least a portion of the link body 23.

[0087] The first fixing hole 222, the second fixing hole 223, the first adapter part 221, and the first circular hole 224 are all provided on the base plate. The surface of the base plate opposite to the first adjusting plate 31 (i.e., the surface 22a of the first end 2a opposite to the first adjusting plate 31) is adapted to form at least a portion of the boundary of the accommodating space.

[0088] The second mounting hole 225 is provided on a pair of wing plates.

[0089] By controlling the degree to which the component on the surface 22a of the first end 2a, which is away from the first adjusting plate 31, protrudes towards the receiving space, excessive use of the receiving space can be avoided. As a result, more receiving space is freed up for the connecting rod body 23.

[0090] In some embodiments, the head 323 of the first eccentric adjustment member 32 may be flush with the surface 22a of the first end 2a that is away from the first adjustment plate 31. For example, the head 323 of the first eccentric adjustment member 32 may be accommodated together with the first rotating shaft portion 321 in the first circular hole 224.

[0091] In some embodiments, reference Figure 9The head 323 of the first eccentric adjustment member 32 can extend beyond the first end 2a and face away from the surface 22a of the first adjustment plate 31, and the distance of the extension can be less than or equal to 2 mm. For example, along the axial direction of the first circular hole 224, the head 323 of the first eccentric adjustment member 32 can protrude slightly beyond the first circular hole 224, but not higher than or flush with the first adapter portion 221 located on both sides of the first circular hole 224.

[0092] This allows for a larger internal space for the hinge 2 to integrate its own structure. Furthermore, the space utilization is high, and the structural layout of the hinge 2 is more compact, which is beneficial for the miniaturization design of the hinge 2.

[0093] In some embodiments, the first adjusting plate 31 may be generally L-shaped, with both arms of the L-shape being plate-shaped, referred to as the first panel and the second panel. The first panel may be opposite to the base plate, and the first adapter hole 313, the second adapter hole 314, the first guide portion 312, and the first waist hole 311 are all formed on the first panel. The second panel may be opposite to the wing plate, and the first mounting hole 15 may be formed on the second panel.

[0094] Furthermore, after the first adjusting plate 31 and hinge 2 are assembled onto the door 11, both the first panel and the bottom plate extend parallel to the z-direction and are connected to the door 11 via the second fastener 13. The two sides of the first panel are in contact with the door 11 and the bottom plate, respectively. The second panel extends horizontally and is connected to the door 11 via a connector.

[0095] There can be a non-zero gap between the second panel and the lower of the pair of wing plates. The size of the gap changes accordingly as the first adjusting plate 31 and the first end 2a undergo relative displacement along the first direction u.

[0096] In a specific implementation, refer to Figure 2 , Figure 5 , Figure 6 and Figure 8 The second adjustment mechanism 4 may include a second adjustment plate 41, fixed to the housing 10. Further, the second adjustment plate 41 may have a second oblique hole 411. The second oblique hole 411 may include a connected straight segment and an arc segment located at at least one end of the straight segment. The extension direction of the straight segment can be determined according to a second direction v.

[0097] Furthermore, the second adjusting mechanism 4 may also include a second eccentric adjusting member 42, specifically including a second rotating shaft portion 421 rotatably connected to the second end 2b and a second eccentric portion 422 located in the second waist hole 411. For example, along the axial direction of the second rotating shaft portion 421, the second eccentric adjusting member 42 sequentially includes a head 423, the second rotating shaft portion 421, and the second eccentric portion 422, wherein the second eccentric portion 422 is eccentric relative to the second rotating shaft portion 421. For example, both the second rotating shaft portion 421 and the second eccentric portion 422 are cylindrical, and their axes are not parallel. (Reference) Figure 8 and Figure 9 In the assembled state, the second eccentric part 422 is located in the second waist hole 411, the second rotating part 421 is accommodated in the second round hole 213 opened in the second end 2b (e.g., the first connecting rod 21), and the head 423 of the second eccentric adjustment member 42 is located on the side of the first connecting rod 21 away from the housing 10.

[0098] When the second rotating shaft 421 rotates, the second eccentric part 422 acts on the inner wall of the second waist hole 411, causing the second end 2b and the second adjusting plate 41 to have a relative displacement in the second direction v. For example, the head 423 of the second eccentric adjusting member 42 can be provided with a mating groove. After the installer uses a suitable tool to insert into the mating groove, the tool can be rotated synchronously to rotate the second eccentric adjusting member 42. As the second rotating shaft 421 rotates on a fixed axis in the second circular hole 213, the second eccentric part 422 rotates in the second waist hole 411 so that the eccentric position acts on different positions of the inner wall of the second waist hole 411, realizing the relative displacement of the hinge 2 and the second adjusting plate 41. In the scenario where the second direction v is the lateral direction, the door 11 can be adjusted left and right at the second end 2b, that is, the door 11 can move left and right relative to the box 10 along the x direction with the first connecting rod 21.

[0099] The second eccentric part 422 and the second waist hole 411 cooperate at the second adjusting plate 41 to achieve adjustment in a second direction (e.g., vertical or horizontal). Since the second adjusting plate 41 with the second waist hole 411 is fixed to the housing 10, the second end 2b of the hinge 2 only needs to have a through hole (e.g., the second round hole 213) for the second eccentric part 422 (or the head 423 of the second eccentric adjusting member 42) to pass through. Thus, the through hole (e.g., the second round hole 213) in the hinge 2 can play a positioning role. The second eccentric adjusting member 42 passes through the second waist hole 411 and the second round hole 213 in sequence to position the relative position of the hinge 2 and the housing 10, avoiding positioning deviation of the hinge 2 relative to the housing 10 during installation, which would affect the overall appearance of the refrigeration appliance 1 when it leaves the factory.

[0100] Furthermore, in a scenario where the refrigeration appliance 1 is equipped with both a first adjustment mechanism 3 and a second adjustment mechanism 4, the first adjustment mechanism 3 and the second adjustment mechanism 4 are distributed at both ends of the hinge 2, resulting in a simple structure that does not interfere with each other.

[0101] In one specific implementation, the second eccentric adjustment member 42 can be riveted to the second end 2b. Specifically, after the second eccentric adjustment member 42 is installed to the first connecting rod 21 and the second adjusting plate 41, the head 423 of the second eccentric adjustment member 42 can be pressed with a tool. The pressed head 423 of the second eccentric adjustment member 42 can form a flange around the second circular hole 213, thereby riveting the second eccentric adjustment member 42 to the first connecting rod 21.

[0102] Furthermore, the flange can cover the side of the second end 2b that faces away from the housing 10.

[0103] Furthermore, the riveting between the second eccentric adjusting member 42 and the first connecting rod 21 can be a rotatable riveting.

[0104] Therefore, the second eccentric adjustment member 42 is riveted to the hinge 2 to achieve connection and positioning, preventing the second eccentric adjustment member 42 from unexpectedly falling off during transportation and daily use of the refrigeration appliance 1. Furthermore, the adjustment part of the second eccentric adjustment member 42, namely the second eccentric part 422, rotates within the second waist hole 411 of the second adjustment plate 41 for adjustment. Thus, the second eccentric adjustment member 42 cooperates with different components to perform connection positioning and relative position adjustment respectively, which helps to distribute the force and avoid the failure of connection positioning and adjustment functions due to damage to a single component.

[0105] In one embodiment, the second adjustment mechanism 4 may further include a second shim (not shown) sandwiched between the head 423 and the second end 2b of the second eccentric adjustment member 42. For example, the second shim may be sandwiched between the head 423 of the second eccentric adjustment member 42 and the side of the first connecting rod 21 facing away from the housing 10.

[0106] The second gasket can be made of a material with a low coefficient of friction. For example, the second gasket can be made of metal.

[0107] Therefore, while ensuring a reliable connection between the hinge 2 and the second eccentric adjustment member 42, it is also ensured that the second eccentric adjustment member 42 can rotate relatively smoothly relative to the hinge 2.

[0108] In a specific implementation, continue to refer to Figure 5 and Figure 8 The second waist hole 411 can extend along the first direction u. That is, the straight segment of the second waist hole 411 can extend along a direction perpendicular to the first direction v.

[0109] Furthermore, combined with Figure 6The second end 2b may be provided with a guide mechanism 211. For example, the first connecting rod 21 may have a second circular hole 213 to accommodate the second rotating shaft portion 421, and guide mechanisms 211 are respectively provided on both sides of the second rotating shaft portion 421 along the second direction u. The guide mechanism 211 is used to guide the second end 2b to move relative to the second adjusting plate 41 along the second direction v during the period when the second eccentric portion 422 acts on the inner wall of the second waist hole 411 at different positions as the second rotating shaft portion 421 rotates.

[0110] For example, if the second direction v is a transverse direction (i.e., a horizontal direction), then the second waist hole 411 on the second adjusting plate 41 is a vertical waist hole, and the first connecting rod 21 has a second round hole 213. The second eccentric adjusting member 42 is riveted to the first connecting rod 21, and the second eccentric part 422 is inserted into the vertical waist hole of the second adjusting plate 41. Two horizontal elongated holes are formed on the first connecting rod 21 to form a guide mechanism 211. A connector can be used to movably connect the first connecting rod 21 to the housing 10 through the elongated holes, so that the first connecting rod 21 can only move horizontally. The connector can be the third fixing member 14 described below.

[0111] This ensures that door 11 is precisely adjusted along the second direction v.

[0112] In one specific implementation, the second end 2b and the housing 10 can be fixed together by a third fastener 14. For example, the third fastener 14 can be a screw, and the first connecting rod 21 and the housing 10 are connected by screw threads.

[0113] Specifically, the second end 2b may have a third fixing hole 212 through which the third fixing member 14 passes. Further, the third fixing hole 212 may be an elongated hole extending along the second direction v to form a guide mechanism 211. In other words, the third fixing member 14 passes through the elongated third fixing hole 212 to fix the first connecting rod 21 to the housing 10. Simultaneously, under the constraint of the cooperation between the third fixing member 14 and the elongated hole, the first connecting rod 21 can only move along the second direction v.

[0114] Therefore, the guide mechanism 211 is formed by reusing the hinge 2 and the fixed structure of the housing 10, which reduces the structural complexity of the hinge 2 and does not increase the thickness of the hinge 2.

[0115] As the second eccentric adjusting member 42 rotates within the second circular hole 213, the eccentric position of the second eccentric part 422 acts on different positions of the inner wall of the second waist hole 411, thereby achieving relative displacement between the hinge 2 and the second adjusting plate 41. During the relative displacement, the third fixing member 14 is connected to the housing 10 and thus remains stationary. The elongated third fixing hole 212 and the third fixing member 14 passing through it cooperate to provide guidance and restriction, ensuring that the first connecting rod 21 can only move relative to the housing 10 along the second direction v.

[0116] In some embodiments, when the refrigeration appliance 1 is manufactured, the third fixing member 14 can be positioned at the middle position of the third fixing hole 212. Accordingly, when the second eccentric adjustment member 42 is rotated, the door 11 and the hinge 2 have two relative displacement degrees of freedom in the second direction v. For example, if the second direction v is the lateral direction, then as the second eccentric adjustment member 42 rotates clockwise or counterclockwise, the door 11 can move left or right relative to the hinge 2.

[0117] In one variation, when the refrigeration appliance 1 is manufactured, the third fixing member 14 can be positioned at one end of the third fixing hole 212. Accordingly, when the second eccentric adjustment member 42 is rotated, the door 11 and the hinge 2 have a single degree of relative displacement freedom in the second direction v. For example, if the second direction v is the lateral direction, and the third fixing member 14 is positioned at the left (or right) end of the third fixing hole 212 along its length when the refrigeration appliance 1 is manufactured, the door 11 is in the adjustable rightmost (or leftmost) position. As the second eccentric adjustment member 42 rotates clockwise (or counterclockwise), the door 11 can move to the left (or right) relative to the hinge 2.

[0118] In a specific implementation, continue to refer to Figure 5 and Figure 8 The second adjusting plate 41 may have a third adapter hole 412 for receiving the third fixing member 14, and the third adapter hole 412 may be a threaded hole. The relative positions of the third fixing member 14 and the second adjusting plate 41 are fixed. Thus, the hinge 2, the housing 10 and the second adjusting plate 41 are connected together by the third fixing member 14.

[0119] In some embodiments, on the same side of the second waist hole 411 along the second direction v, the second adjusting plate 41 may have two third adapter holes 412 arranged side by side along the second direction v. One of the two third adapter holes 412 located on the same side of the second waist hole 411 along the second direction v is applied to the first door 115, and the other is applied to the second door 116.

[0120] In some embodiments, when the refrigeration appliance 1 leaves the factory, the third fixing member 14 can be tightened to reliably connect the housing 10, the second adjusting plate 41, and the first connecting rod 21 together. When it is necessary to operate the second eccentric adjusting member 42 to adjust the position of the door 11, the third fixing member 14 is loosened to facilitate the relative movement of the second adjusting plate 41 and the first connecting rod 21. After the position adjustment of the door 11 along the second direction v is completed, the third fixing member 14 is tightened again to re-secure the connection between the first connecting rod 21 and the housing 10.

[0121] In a specific implementation, continue to refer to Figure 5The housing 10 may include a crossbeam 102 forming at least a portion of the front surface of the housing 10. Along the depth direction (e.g., the y-direction) of the refrigeration appliance 1, a second adjusting plate 41 and a hinge 2 may be located on opposite sides of the crossbeam 102. That is, a first connecting rod 21 is connected to the front of the crossbeam 102, while the second adjusting plate 41 is located behind the crossbeam 102 and is not visible to the outside.

[0122] Furthermore, the crossbeam 102 may have a third waist hole 103 corresponding to the second waist hole 411. The second eccentric portion 422 may be partially located in the third waist hole 103, with the remaining portion located in the second waist hole 411. The extending direction of the third waist hole 103 may be consistent with the extending direction of the second waist hole 411. The dimensions of the third waist hole 103 and the second waist hole 411 may also be consistent.

[0123] Furthermore, the second adjusting plate 41 can be located within the insulation layer of the housing 10. During foaming, adhesive tape can be applied to the side of the second adjusting plate 41 facing away from the crossbeam 102 to prevent the foaming material from directly contacting the second adjusting plate 41.

[0124] By placing the second adjustment plate 41 inside the housing 10, the thickness of the hinge 2 can be increased without adding extra thickness, allowing the refrigeration appliance 1 of this embodiment to use a thinner door.

[0125] As the second pivot 421 rotates about its fixed axis within the second circular hole 213, a portion of the second eccentric portion 422 rotates within the second waist hole 411, and the remaining portion of the second eccentric portion 422 rotates within the third waist hole 103. This causes the eccentric position to act on different positions of the inner walls of the second waist hole 411 and the third waist hole 103, thereby achieving relative displacement between the hinge 2 and the housing 10. As a result, the thickness of the second adjusting plate 41 can be reduced, ensuring sufficient space for the insulation layer behind the crossbeam 102 and preventing cold leakage at the hinge 2.

[0126] In a specific implementation, continue to refer to Figure 5 The second adjusting plate 41 can have two second waist holes 411 arranged side by side along the second direction v. One of the two second waist holes 411 is used for the first door 115, and the other of the two second waist holes 411 is used for the second door 116. That is to say, as the installation position of the second adjusting plate 41 on the housing 10 changes, one of the two second waist holes 411 is aligned with the third waist hole 103.

[0127] For example, refer to Figure 8 The second adjusting plate 41 is applied to the first door 115 and installed on it. Figure 1When viewed from the upper left corner of the housing 10, the rightmost third adapter 412 of the two third adapter holes 412 located on the same side as the second waist hole 411 aligns with the fourth adapter hole 104 on the crossbeam 102. The third fixing member 14 passes through the third fixing hole 212, the fourth adapter hole 104, and the third adapter hole 412 in sequence, so that the first connecting rod 21, the crossbeam 102, and the second adjusting plate 41 are threadedly connected. Furthermore, the rightmost second waist hole 411 of the two second waist holes 411 aligns with the third waist hole 103 on the crossbeam 102, and the second eccentric adjusting member 42 passes through the second round hole 213, the third waist hole 103, and the rightmost second waist hole 411 in sequence.

[0128] For example, the second adjusting plate 41 is applied to the second door 116 and installed on... Figure 1 When viewed from the upper right corner of the housing 10, the leftmost of the two third adapter holes 412 located on the same side as the second waist hole 411 is aligned with the fourth adapter hole 104 on the crossbeam 102. The third fixing member 14 passes through the third fixing hole 212, the fourth adapter hole 104, and the third adapter hole 412 in sequence, so that the first connecting rod 21, the crossbeam 102, and the second adjusting plate 41 are threadedly connected. Furthermore, the leftmost of the two second waist holes 411 is aligned with the third waist hole 103 on the crossbeam 102, and the second eccentric adjusting member 42 passes through the second round hole 213, the third waist hole 103, and the leftmost second waist hole 411 in sequence.

[0129] Similarly, one of the two second waist holes 411 can be used in the third door 117, and the other can be used in the fourth door 118. For example, the connection between the lower hinge of the third door 117 and the housing 10 can refer to the connection between the upper hinge of the first door 115 and the housing 10, and the connection between the lower hinge of the fourth door 118 and the housing 10 can refer to the connection between the upper hinge of the second door 116 and the housing 10.

[0130] Therefore, the same second adjustment plate 41 can be compatiblely installed on the left or right side of the housing 10, reducing the number of molds.

[0131] In some embodiments, continue to refer to Figure 5 and Figure 6After the connecting rod body 23 is connected to the first connecting rod 21, the third fixing hole 212 closer to the connecting rod body 23 is covered by the connecting rod body 23, which may hinder the installation of the third fixing member 14. In this example, the first connecting rod 21 may have a second hole 17, which directly or indirectly connects to the third fixing hole 212 and has a larger diameter. During installation, the third fixing member 14 is first inserted into the third fixing hole 212 through the second hole 17. Then, the first connecting rod 21 with the third fixing member 14 connected is placed in front of the crossbeam 102, the second adjusting plate 41 is placed behind the crossbeam 102, and the third fixing member 14 is passed through the fourth adapter hole 104 and the third adapter hole 412 in sequence. Finally, the third fixing member 14 is tightened to connect the first connecting rod 21, the crossbeam 102, and the second adjusting plate 41 together.

[0132] In some embodiments, the end of the third fixing hole 212 further away from the link body 23 may be open. This allows for a reduction in the length of the first link 21.

[0133] During installation, the third fixing hole 212, which serves as the guide mechanism 211, can be used to fix the third fixing member 14 at any position, resulting in the door 11 and the cabinet 10 having inconsistent lateral relative positions at the factory. In this embodiment, both the second waist hole 411 and the third waist hole 103 are vertical waist holes, thus ensuring that the relative positions of the second round hole 213 and the second waist hole 411 in the lateral direction are unique and fixed. Therefore, the second eccentric adjustment member 42 can play a positioning role, ensuring that the hinge 2 has a more precise fixed position on the cabinet 10, and that the lateral relative positions of the door 11 and the cabinet 10 at the factory meet a uniform standard.

[0134] In some embodiments, the length of the straight segment of the second waist hole 411 can be taken from [1.5, 3] mm. For example, the lengths of the straight segments of both the second waist hole 411 and the third waist hole 103 can be 3 mm. Accordingly, the maximum distance that the door 11 can be adjusted along the second direction v is 3 mm.

[0135] In some embodiments, continue to refer to Figure 5 The second adjusting plate 41 may be provided with multiple reinforcing ribs 413 to increase the structural strength of the second adjusting plate 41.

[0136] In a specific implementation, refer to Figure 1 , Figure 10 and Figure 11 The second adjusting plate 41 can have two second waist holes 411 arranged side by side along the first direction u. One of the two second waist holes 411 is used for the first door 115, and the other is used for the third door 117. That is to say, the first door 115 and the third door 117 are displaced in the second direction v through the same second adjusting plate 41.

[0137] Furthermore, each of the second waist holes 411 has a third adapter hole 412 on both sides along the second direction v. The crossbeam 102 located in front of the second adjusting plate 41 also has two rows of holes arranged side by side along the first direction u (e.g., the z direction), wherein each row of holes along the second direction v is successively a fourth adapter hole 104, a third waist hole 103 and a fourth adapter hole 104.

[0138] For example, the lower hinge of the first door 115 passes sequentially through the fourth adapter hole 104 and the third adapter hole 412 located upward along the z-direction via the third fixing member 14, thereby fixing the lower hinge of the first door 115 together with the housing 10 and the second adjusting plate 41. Furthermore, the lower hinge of the first door 115 achieves displacement in the second direction v by acting within the second waist hole 411 located upward along the second eccentric adjusting member 42. The lower hinge of the second door 116 can also be connected to the housing 10 using a similar connection method.

[0139] For example, the upper hinge of the third door 117 passes sequentially through the fourth adapter hole 104 and the third adapter hole 412 located downwards in the z-direction via the third fixing member 14, thereby fixing the upper hinge of the third door 117 to the housing 10 and the second adjusting plate 41 together. Furthermore, the upper hinge of the third door 117 achieves displacement in the second direction v by acting within the second waist hole 411 located downwards in the second adjusting plate 41 via the second eccentric adjusting member 42. The upper hinge of the fourth door 118 can also be connected to the housing 10 using a similar connection method.

[0140] Therefore, a single second adjustment plate 41 can be reused to support the relative position adjustment of multiple doors 11 and the housing 10, reducing the number of parts.

[0141] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of this disclosure, even when only a single embodiment is described with respect to a particular feature. The examples of features provided in this disclosure are intended to be illustrative and not limiting, unless otherwise stated. In practice, one or more technical features of the dependent claims may be combined with technical features of the independent claims, and technical features from the respective independent claims may be combined in any suitable manner rather than solely by the specific combinations listed in the claims.

[0142] While the above disclosure is provided, it is not limited thereto. Any person skilled in the art may make various alterations and modifications without departing from the spirit and scope of this disclosure; therefore, the scope of protection of this disclosure shall be determined by the scope defined in the claims.
