[0038] Currently, refrigerator doors are usually connected to the refrigerator body through hinges. The hinges include a hinge plate and a hinge shaft connected to the hinge plate. The hinge plate is generally fixed to the refrigerator body by screws. Delivery personnel need to spend a long time to remove and install the screws, which is time-consuming and labor-intensive to install and deliver, and has low delivery efficiency.

[0039] For ease of description, unless otherwise specified, the directions of up, down, left, right, front, and back in this article are all based on the state of the refrigerator when it is in use. The refrigerator door is the front, the opposite direction is the back, and the vertical direction is the up and down direction.

[0040] Figure 1 It is a structural schematic diagram of a refrigerator according to an embodiment of the present invention. Figure 2 yes Figure 1 An enlarged schematic diagram of the middle and upper hinge mechanism 30 area.

[0041] See also Figure 1 and Figure 2 The refrigerator provided by the embodiment of the present invention mainly includes a cabinet 1, a door 2 and a hinge mechanism.

[0042] The box body 1 adopts a rectangular hollow structure. It is understandable that the box body 1 can also adopt a hollow shell structure of other shapes.

[0043] The cabinet 1 can be provided with multiple, mutually separated refrigeration compartments (not shown in the figure). Each of the separated refrigeration compartments can be used as an independent storage space, such as a freezer, refrigerator, and temperature-changing chamber, to meet different refrigeration requirements such as freezing, refrigeration, and temperature-changing according to different food types, and to store them. The multiple refrigeration compartments can be arranged vertically or horizontally.

[0044] A box liner (not shown) is provided in the box body 1, and a refrigeration compartment is formed in the box liner. It is understandable that a plurality of box liner can be provided in the box body 1, and each box liner can form one or more refrigeration compartments.

[0045] See also Figure 1 The door 2 is provided at the front side of the refrigerator body 1 for opening and closing the refrigeration compartment. The door 2 and the refrigerator body 1 may be connected by two or more hinge mechanisms, the hinge axes of which are arranged along the same axis, so that the door 2 of the refrigerator can rotate about the axis to open and close the refrigerator door 2 and open and close the corresponding refrigeration compartment.

[0046] See also Figure 1 In some embodiments, the hinge mechanism includes an upper hinge mechanism 30 and a lower hinge mechanism 40. The upper hinge mechanism 30 is provided at one end of the top of the door body 2, and the top end of the door body 2 is detachably hinged to the hinge shaft of the upper hinge mechanism 30. The lower hinge mechanism 40 is provided at one end of the bottom of the door body 2 and corresponds to the upper hinge mechanism 30. The hinge shafts of the upper hinge mechanism 30 and the lower hinge mechanism 40 are arranged along the same axis, and the corresponding end portion of the bottom of the door body 2 is detachably hinged to the hinge shaft of the lower hinge mechanism 40, so that the door body 2 can rotate around the axis to realize the opening and closing of the refrigerator door body 2.

[0047] Figure 3 yes Figure 2 Schematic diagram of the decomposition structure. Figure 4 yes Figure 3 Schematic diagram of the structure of the middle mounting seat 3.

[0048] See also Figure 2 and Figure 3 In some embodiments, the upper hinge mechanism 30 includes a mounting base 3, an upper hinge 4, a pressure rod assembly 5 and a hinge cover (not shown in the figure).

[0049] The mounting seat 3 is fixed to the corner of the top of the box body 1 to provide an installation position and installation space for the upper hinge 4 and the pressure rod assembly 5.

[0050] See also Figure 3 and Figure 4The rear end of the mounting seat 3 is provided with an upwardly extending clamping wall 31, which protrudes from the top surface of the box body 1 and is used for the rear end of the pressure rod assembly 5 to be detachably clamped and installed.

[0051] Mounting base 3 has upwardly extending mounting walls 32 on its left and right sides, both protruding from the top surface of housing 1. The two mounting walls 32 are arranged opposite each other on the left and right sides. The two mounting walls 32 are used to limit the left and right positions of upper hinge 4 and to provide hinged mounting for the front end of pressure rod assembly 5.

[0052] See also Figure 2 and Figure 3 In some embodiments, the mounting base 3 is fixed on the inner top surface of the box body 1, such as by screw fixation, and is fixed to the inner top surface of the box body 1 as a whole. The mounting base 3 is buried in the foam layer, that is, the mounting base 3 can be buried inside the box body 1. At the same time, the top surface of the box body 1 is provided with through-holes 11 arranged respectively opposite to the clamping wall 31 and the mounting wall 32. The clamping wall 31 and the mounting base 3 can respectively pass through the corresponding through-holes 11 and extend upward out of the top surface of the box body 1. This solution can hide the mounting base 3 inside the box body 1, making the appearance of the refrigerator neat and beautiful, and can also improve the installation strength of the upper hinge 4.

[0053] In some embodiments, a first fixing hole 12 is provided on the top surface of the box body 1, and a second fixing hole 34 is provided on the mounting base 3, which is arranged corresponding to the first fixing hole 12. The mounting base 3 is fixed to the inner top surface of the box body 1 by screws inserted through the first fixing hole 12 and the second fixing hole 34.

[0054] It should be noted that, in some other embodiments, the mounting base 3 can also be fixed directly to the top surface of the box body 1 by screws, that is, fixed to the outside of the box body 1. For example, the mounting base 3 is fixed above the top surface of the box body 1 by screws inserted into the fixing holes.

[0055] Figure 5 yes Figure 3 Schematic diagram of the structure of the middle upper hinge 4.

[0056] See also Figure 5 The upper hinge 4 is located above the top surface of the box body 1, that is, the upper hinge 4 is located on the outside of the box body 1. The rear end of the upper hinge 4 is fixed to the top of the box body 1, and the front end of the upper hinge 4 is hinged to one end of the top of the door body 2, thereby realizing the opening and closing of the door body 2. At the same time, the rear end of the upper hinge 4 is detachably mounted on the mounting base 3, allowing the upper hinge 4 to be directly removed from the top of the box body 1 without the need for screw removal, saving operation steps and time.

[0057] In some embodiments, the upper hinge 4 includes a hinge plate 41 and a hinge shaft 42 protruding from the front end of the hinge plate 41. The hinge plate 41 is detachably fixed to the mounting base 3 and the top of the box body 1, and is detachably clamped between the two mounting walls 32. The hinge shaft 42 is used for rotational connection with the door body 2.

[0058] In some embodiments, the hinge shaft 42 is detachably connected to the door body 2, allowing the upper hinge 4 to be completely removed from the housing 1 and the door body 2 for easy assembly and disassembly and separate transportation. For example, a shaft cavity is recessed at the corresponding end of the top of the door body 2, and the hinge shaft 42 is detachably inserted into the shaft cavity and can rotate relative to the shaft cavity, thereby achieving a rotational and detachable connection between the hinge shaft 42 and the door body 2.

[0059] See also Figures 2 to 5 In some embodiments, the top surface of the mounting base 3 is provided with an upwardly extending positioning post 33. The positioning post 33 passes through the top of the housing 1 and is exposed on the top surface of the housing 1. In other words, the positioning post 33 protrudes from the top surface of the housing 1 and extends upward. The hinge plate 41 is provided with a positioning hole 411 that is arranged opposite the positioning post 33 on the mounting base 3. The positioning hole 411 allows the hinge plate 41 of the upper hinge 4 to be accurately and quickly positioned and installed on the mounting base 3.

[0060] In some embodiments, two positioning posts 33 and two positioning holes 411 are provided, spaced apart from each other. It is understood that multiple groups of positioning posts 33 and positioning holes 411 can be provided, with one-to-one correspondence between the positioning posts 33 and the positioning holes 411.

[0061] See also Figures 2 to 5 The hinge plate 41 is detachably mounted between the two mounting walls 32 of the mounting base 3. The two mounting walls 32 can be used to limit the left and right positions of the upper hinge 4, preventing the hinge plate 41 from moving left and right on the top of the box body 1. At the same time, the hinge plate 41 can be easily removed from between the two mounting walls 32.

[0062] In some embodiments, the left and right sides of the upper hinge 4 are each provided with a recessed slot 412 that is arranged opposite the mounting wall 32. When the hinge plate 41 of the upper hinge 4 is clamped between the two mounting walls 32, the two mounting walls 32 engage with a respective recessed slot 412, thereby preventing the hinge plate 41 from moving forward and backward in the housing 1, thereby limiting the front-to-back position of the upper hinge 4. The two mounting walls 32 cooperate with each other to limit the left and right position of the hinge plate 41, allowing the hinge plate 41 to be installed and removed only from the top and bottom relative to the mounting walls 32.

[0063] Figure 6 yes Figure 3 Schematic diagram of the structure of the intermediate pressure rod assembly 5. Figure 7 yes Figure 6 Schematic diagram of the decomposition from another perspective. Figure 8 yes Figure 6 Schematic diagram of the structure in another state.

[0064] See also Figures 6 to 8 , and combined with Figure 2 and Figure 3 The pressure rod assembly 5 is disposed on the mounting base 3 and is located above the upper hinge 4. The two sides of the front end of the pressure rod assembly 5 are respectively hinged to a mounting wall 32, thereby clamping and fixing the upper hinge 4 between the mounting base 3 and the pressure rod assembly 5, that is, between the top surface of the box body 1 and the pressure rod assembly 5. The rear end of the pressure rod assembly 5 is detachably engaged with the engaging wall 31, thereby forming a secondary locking state, maintaining the pressure rod assembly 5 clamped to the upper hinge 4, so that the upper hinge 4 is stably mounted and fixed to the box body 1.

[0065] See also Figures 6 to 8 In some embodiments, the pressure rod assembly 5 includes a pressing member 51 and a locking member 52 that are slidably connected to each other. It should be noted that the pressing member 51 and the locking member 52 are an integral connection structure and are assembled as a whole at the factory. They do not need to be disassembled during transportation and disassembly.

[0066] See also Figure 2 and Figure 3 The pressing member 51 is located above the upper hinge 4. The front end of the pressing member 51 is detachably hinged to a mounting wall 32 on either side. The hinge axes on both sides of the pressing member 51 are coaxial and extend laterally, allowing the rear end of the pressing member 51 to rotate up and down. When the pressing member 51 rotates downward, it compresses and clamps the upper hinge 4 between the mounting base 3 and the pressing member 51, thereby firmly securing the upper hinge 4 to the top surface of the box body 1.

[0067] See also Figures 6 to 8 In some embodiments, the pressing member 51 includes an integrally formed hinge arm 511 and a supporting arm 512 .

[0068] The hinged arm 511 extends laterally and is positioned between the two mounting walls 32. A hinged portion 5111 protrudes from each end of the hinged arm 511. Furthermore, a mounting hole 321 is defined in each mounting wall 32. The mounting holes 321 are open circumferentially, forming a circumferentially open hole structure. The two mounting holes 321 are coaxially arranged relative to each other. Therefore, the hinged portions 5111 at each end of the hinged arm 511 can be removably mounted in the mounting holes 321 on the two mounting walls 32 through the openings of the mounting holes 321, thereby allowing the ends of the hinged arm 511 to be removably hinged to the mounting holes 321.

[0069] It should be noted that the opening direction of the mounting hole 321 can be set at the front side of the mounting wall 32 , and can also be set at the rear side of the mounting wall 32 .

[0070] The abutting arm 512 extends rearward from the rear end of the hinge arm 511 and is used to abut against the upper hinge 4, thereby pressing the upper hinge 4 against the top surface of the box body 1 or the top surface of the mounting base 3. The rear end of the abutting arm 512 can extend to one side of the clamping wall 31, thereby facilitating clamping with the clamping wall 31 to maintain the pressing force of the abutting arm 512 on the upper hinge 4.

[0071] See also Figures 6 to 8 The locking member 52 is slidably connected to the rear end of the supporting arm 512. The supporting arm 512 is provided with an elongated hole 5121, through which the locking member 52 is slidably connected to the pressing member 51.

[0072] In some embodiments, the elongated hole 5121 extends along the front-to-back direction, the rear end of the elongated hole 5121 is close to the engaging wall 31 , and the front end of the elongated hole 5121 is close to the engaging wall 31 .

[0073] When the locking member 52 slides backward along the elongated hole 5121, it approaches the engaging wall 31, thereby engaging the locking member 52 with the engaging wall 31, preventing the locking member 52 from moving up and down. This locks the pressing member 51 and the pressure rod assembly 5 to the mounting seat 3, maintaining the pressing member 51's pressing state against the upper hinge 4. The locking member 52 and the pressing member 51 cooperate to form a two-stage locking structure, which effectively prevents the pressing member 51 from accidentally rotating and causing unlocking.

[0074] When the locking member 52 slides forward along the elongated hole 5121 , it can face away from and away from the engaging wall 31 , thereby disengaging the locking member 52 from the engaging wall 31 , thereby releasing the pressing state of the pressing member 51 on the upper hinge 4 .

[0075] It can be understood that in some other embodiments, the elongated hole 5121 can also extend in other directions, such as left and right directions or diagonal directions. It only requires that one end of the elongated hole 5121 is close to the clamping wall 31 and the other end is away from the clamping wall 31, so that the locking member 52 and the clamping wall 31 can be moved closer to each other or away from each other, thereby achieving mutual clamping or mutual disengagement between the locking member 52 and the clamping wall 31.

[0076] See also Figure 7 In some embodiments, the compression rod assembly 5 further includes a sliding member 53. The locking member 52 is disposed above the compression member 51. The upper end of the sliding member 53 is connected to the locking member 52, and the lower end of the sliding member 53 is slidably inserted into the elongated hole 5121. The locking member 52 is slidably connected to the compression member 51 via the sliding member 53, and the locking member 52 is slidably connected to the compression member 51 as a whole. When assembling and disassembling the upper hinge 4 and the door body 2, there is no need to disassemble the locking member 52 and the compression member 51.

[0077] In some embodiments, the sliding member 53 is a rivet, that is, the locking member 52 is riveted to the elongated hole 5121 via a rivet, and the rivet can slide relative to the elongated hole 5121. The elongated hole 5121 can be an oblong hole structure. In other embodiments, the sliding member 53 can also be integrally formed with the locking member 52, forming a sliding portion of the locking member 52.

[0078] See also Figures 2 to 8 In some embodiments, a recess 521 is formed on the side of the locking member 52 facing the engaging wall 31. When the locking member 52 slides toward the engaging wall 31, it engages the engaging wall 31 via the recess 521, locking the pressing member 51 and the pressure rod assembly 5 to the mounting seat 3 and maintaining the pressing state of the pressing member 51 on the upper hinge 4. When the locking member 52 slides away from the engaging wall 31, the recess 521 disengages from the engaging wall 31, thereby disengaging the locking member 52 from the engaging wall 31 and releasing the pressing state of the pressing member 51 on the upper hinge 4.

[0079] See also Figure 2 、 Figure 4 and Figure 7 In some embodiments, the top of the engaging wall 31 is provided with an upwardly extending engaging portion 311, and laterally protruding limiting portions 312 are provided on both sides of the top of the engaging portion 311. The engaging portion 311 and limiting portions 312 form a T-shaped or I-shaped structure as a whole. When the locking member 52 slides toward the engaging wall 31, the engaging portion 311 engages with the bayonet 521, and the limiting portions 312 engage with the top surface of the locking member 52 near the bayonet 521, thereby enabling the locking member 52 to be detachably engaged with the engaging wall 31.

[0080] It should be noted that, in some other embodiments, the limiting portion 312 may also be protruded only on one side of the top of the clamping portion 311 , which can also clamp and fix the locking member 52 on the clamping wall 31 .

[0081] See also Figures 6 to 8 In some embodiments, downwardly extending retaining ribs 522 are provided at the front and rear ends of the locking member 52. As the locking member 52 slides, the retaining ribs 522 abut against the sidewalls of the pressing member 51, thereby limiting the position of the locking member 52 and preventing it from rotating relative to the pressing member 51, making it easier for personnel to disassemble and assemble the compression rod assembly 5.

[0082] See also Figure 1 and Figure 2 The hinge cover is arranged on the top of the box body 1 and is used to cover the hinge 4, the mounting base 3 and the pressure rod assembly 5, thereby making the top of the box body 1 neat and beautiful.

[0084] See also Figures 9 to 12 The assembly process of the upper hinge mechanism 30 is as follows: first, fix the mounting base 3 on the box body 1, and then snap-fit ​​the upper hinge 4 onto the mounting base 3. Figure 9 Then the pressure rod assembly 5 is mounted on top of the upper hinge 4 and mounted on the mounting wall 32, as shown Figure 9 Rotate the lever assembly 5 so that the rear end of the locking member 52 and the pressing member 51 is close to the clamping wall 31, as shown Figure 10 Finally, the locking member 52 is slid close to the clamping wall 31, so that the locking member 52 is clamped on the clamping wall 31 of the mounting base 3, as shown Figure 11 and Figure 12 shown.

[0085] See also Figure 3 , the mounting base 3 needs to be pre-installed and fixed on the box body 1. Specifically, before the box body 1 is foamed, the mounting base 3 can be fixed to the inside of the box body 1 with screws, and the clamping wall 31, the mounting wall 32 and the positioning column 33 of the mounting base 3 are protruded from the top surface of the box body 1. Then, when the box body 1 is foamed, the mounting base 3 can be buried inside the box body 1.

[0086] See also Figure 9 When installing the upper hinge 4, the slot 412 of the upper hinge 4 faces the mounting wall 32, allowing the upper hinge 4 to be installed downward and clamped between the two mounting walls 32. At this time, the positioning hole 411 on the upper hinge 4 faces the positioning post 33 on the mounting base 3, so that the positioning post 33 is inserted and fixed in the positioning hole 411, thereby limiting the two degrees of freedom of the upper hinge 4 in the horizontal direction, namely the front-back limit and the left-right limit.

[0087] See also Figure 9 and Figure 10 When installing the pressure rod assembly 5, first put the hinge parts 5111 at both ends of the hinge arm 511 into the mounting hole 321 from the opening of the mounting hole 321, and then make the pressing member 51 hinged on the mounting wall 32, as shown in FIG. Figure 9 Then rotate the rear end of the pressing member 51 and the locking member 52 downward and backward so that the pressing member 51 presses the upper hinge 4, as shown. Figure 10 Finally, slide the locking member 52 to engage with the engaging wall 31, as shown. Figure 11 and Figure 12 At this time, the engaging wall 31 can prevent the locking member 52 and the pressing member 51 from rotating, thereby maintaining the locking state of the pressure rod assembly 5 and the upper hinge 4.

[0088] When unlocking, the locking member 52 is slid in the reverse direction to disengage the locking member 52 from the engaging wall 31 and release the pressing state of the pressing member 51 on the upper hinge 4, so that the entire pressure rod assembly 5 can be directly removed from the mounting wall 32 of the fixing base; after removing the upper hinge 4, the upper hinge 4 can be separated from the box body 1, so that the door body 2 and the box body 1 can be transported separately. During the disassembly process, when the door body 2 needs to be disassembled and assembled, it is only necessary to disassemble the pressure rod assembly 5 and the upper hinge 4 in sequence, without removing the mounting base 3 or removing and assembling screws. This can reduce the difficulty of disassembly and assembly, save disassembly and assembly time, and improve disassembly and assembly efficiency and delivery efficiency.

[0089] Figure 13 yes Figure 3 Another assembly diagram of the middle mounting seat. Figure 14 is Figure 13 Schematic diagram of the assembly of the hinge and pressure rod assembly 5 installed on the basis. Figure 15 yes Figure 14 Schematic diagram of the structure after assembly.

[0090] See also Figures 13 to 15 , the refrigerator of this embodiment and Figures 2 to 12 The structure of the refrigerator in FIG is similar, except that the installation position of the mounting base 3 is different.

[0091] In this embodiment, mounting base 3 is fixed to the top surface of housing 1, that is, it is fixed to the outside of housing 1. For example, mounting base 3 is fixed to the top surface of housing 1 using screws inserted through fixing holes. In this case, the engaging wall 31, mounting wall 32, and positioning post 33 of mounting base 3 all protrude from the top surface of housing 1 and extend upward.

[0092] In some embodiments, the housing 1 is provided with a first fixing hole 12, and the mounting base 3 is provided with a second fixing hole 34, which is arranged opposite the first fixing hole 12. The second fixing hole 34 is configured as a waist hole structure. Due to the waist hole structure, when the mounting base 3 is fixed to the housing 1 via screws, the position of the mounting base 3 can be adjusted, such as left and right or front and back, to more precisely position the mounting base 3 and its positioning post 33, thereby enabling more accurate installation and connection of the hinge 4.

[0093] In some embodiments, the upper hinge mechanism 30 further includes a reinforcement plate 6, which is disposed on the inner top surface of the housing 1, directly below the mounting base 3. The reinforcement plate 6 serves to increase the structural strength of the top surface of the housing 1 and cooperates with the mounting base 3 to secure the mounting base 3 to the top surface of the housing 1. Specifically, the reinforcement plate 6 includes a third fixing hole 61, which is arranged opposite the first fixing hole 12 and the second fixing hole 34. Screws can be sequentially inserted through the first fixing hole 12, the second fixing hole 34, and the third fixing hole 61, thereby securing the mounting base 3 and the reinforcement plate 6 to the housing 1.

[0094] During the refrigerator assembly process, the position of the reinforcing plate 6 is prone to offset due to processing techniques such as foaming, which can lead to inaccurate positioning of the third fixing hole 61 and ultimately inaccurate installation of the upper hinge 4. The second fixing hole 34 of the waist-hole structure allows the position of the mounting base 3 to be adjusted, thereby ensuring a more accurate installation position for the upper hinge 4 and, consequently, for the door body 2, effectively preventing defects such as skewed door body 2 or improper closing.

[0095] It should be noted that in this embodiment, the mounting base 3 can be adjusted and fixed by a professional before shipment. When the door body 2 needs to be disassembled or assembled, the operator or user only needs to unlock or lock the upper hinge 4 using the pressure rod assembly 5, without having to remove or assemble the screws of the mounting base 3. This facilitates operation and improves assembly and disassembly efficiency. Furthermore, the upper hinge 4 can be accurately positioned at all times, allowing even non-professionals to ensure that the door body 2 is properly installed.

[0096] Based on the above technical solution, the embodiments of the present invention have at least the following advantages and positive effects:

[0097] In the refrigerator of the embodiment of the present invention, the cabinet 1 and the door 2 are connected by an upper hinge mechanism 30. At the same time, in the upper hinge mechanism 30, the mounting base 3, the upper hinge 4 and the pressure rod assembly 5 are coordinated. The mounting base 3 is arranged at the top of the cabinet 1, which facilitates the installation of the upper hinge 4 and can improve the installation strength of the upper hinge 4. The upper hinge 4 is detachably arranged just above the mounting base 3, and the pressure rod assembly 5 is detachably clamped on the mounting base 3. The upper hinge 4 is clamped and fixed between the mounting base 3 and the pressure rod assembly 5, which facilitates the disassembly of the upper hinge 4 from the cabinet 1. When disassembling the door 2, it is only necessary to disassemble the pressure rod assembly 5 and the upper hinge 4 in sequence. There is no need to disassemble the mounting base 3 or to perform screw disassembly and fixing. This is beneficial for saving disassembly and assembly time during transportation and improving disassembly and assembly efficiency and delivery efficiency.

[0098] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are intended to be illustrative and exemplary rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims.
