[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 Magnified schematic of the upper-middle hinge 4 region.

[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.

[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 6.

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

[0051] See also Figure 3 and Figure 4 The 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 detachably clamping and installing the rear ends of the upper hinge 4 and the pressure rod assembly 5 respectively.

[0052] 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.

[0053] 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.

[0054] In some embodiments, corresponding fixing holes are provided on the top surface of the box body 1 and on the mounting base 3 , so that the mounting base 3 can be fixed to the inner top surface of the box body 1 by screws passing through the fixing holes.

[0055] It should be noted that, in some other embodiments, the mounting base 3 may also be directly fixed to the top surface of the box body 1 by screws, that is, fixed to the outside of the box body 1 .

[0056] Figure 5 yes Figure 3 Schematic diagram of the structure of the middle upper hinge 4.

[0057] 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.

[0058] 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 the hinge shaft 42 is used to rotate with the door body 2.

[0059] 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.

[0060] 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.

[0061] 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 may be provided, with one-to-one correspondence between the positioning posts 33 and the positioning holes 411.

[0062] See also Figure 2 、 Figure 4 and Figure 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.

[0063] 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.

[0064] See also Figure 2 、 Figure 4 and Figure 5The rear end of the hinge plate 41 is provided with a first tilted portion 413 extending rearward. A slot 311 is defined at the bottom of the engaging wall 31, near the top surface of the mounting base 3. The first tilted portion 413 of the hinge plate 41 is removably inserted and fixed into the slot 311, thereby enabling the rear end of the upper hinge 4 to be engaged and fixed to the mounting base 3, thereby limiting the rear end of the upper hinge 4 in the vertical direction.

[0065] In some embodiments, the first tilting portion 413 gradually extends upward in an inclined manner from front to back, gradually moving away from the bottom surface of the upper hinge 4, thereby enabling the first tilting portion 413 to bend upward and tilt relative to the hinge plate 41. When the first tilting portion 413 is inserted and fixed in the slot 311 of the engaging wall 31, the front end of the hinge plate 41 can tilt upward, thereby enabling the engaging slot 412 of the hinge plate 41 to face the mounting wall 32, thereby allowing the hinge plate 41 to be smoothly and detachably installed between the two mounting walls 32.

[0066] In some embodiments, a laterally extending retaining rib 312 is protruded from one side of the latching wall 31. A slot 311 is formed below the retaining rib 312, that is, between the retaining rib 312 and the top surface of the housing 1. The slot 311 is a laterally open structure. When the first raised portion 413 at the rear end of the hinge plate 41 is inserted into the slot 311, the rear end of the hinge plate 41 is relatively fixed to the top surface of the housing 1, thereby achieving vertical positional restraint of the rear end of the hinge plate 41.

[0067] See also Figure 4 and Figure 5 In some embodiments, the rear end of the engaging wall 31 is provided with a rearwardly extending second raised portion 414. The second raised portion 414 is spaced apart from the first raised portion 413, and a positioning groove 415 is formed between the second raised portion 414 and the first raised portion 413. When the raised portion at the rear end of the hinge plate 41 is inserted and fixed in the slot 311, the engaging wall 31 can be engaged in the positioning groove 415, thereby positioning the rear end of the hinge plate 41 on the engaging wall 31 and limiting the left and right position of the rear end of the hinge plate 41.

[0068] Figure 6 yes Figure 3 Schematic diagram of the structure of the intermediate pressure rod assembly 5. Figure 7 yes Figure 6 Exploded diagram in another state.

[0069] See also Figure 6 and Figure 7 , and combined with Figure 2 and Figure 3The pressure rod assembly 5 is provided 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, and the rear end of the pressure rod assembly 5 is detachably engaged with the engaging wall 31, and can clamp and fix the upper hinge 4 to the top of the box body 1, thereby stably mounting and fixing the upper hinge 4 to the box body 1.

[0070] See also Figure 6 and Figure 7 In some embodiments, the pressure rod assembly 5 includes a pressing member 51 and a locking rod 52 that are rotatably connected to each other. It should be noted that the pressing member 51 and the locking rod 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.

[0071] 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.

[0072] See also Figure 6 and Figure 7 In some embodiments, the pressing member 51 includes an integrally formed hinge arm 511 , a supporting portion 512 and an elastic arm 513 .

[0073] 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 circumferentially open and coaxially arranged. Therefore, the hinged portions 5111 at each end of the hinged arm 511 can be removably mounted to the mounting holes 321 on the two mounting walls 32, thereby allowing the ends of the hinged arm 511 to be removably hinged to the mounting holes 321.

[0074] 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 .

[0075] The abutting portion 512 extends backward from the rear end of the hinge arm 511 and bends downward. The abutting portion 512 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.

[0076] The elastic arm 513 is bent upward and extended backward from the rear end of the supporting portion 512. The rear end of the elastic arm 513 can be extended to one side of the clamping wall 31, thereby facilitating clamping with the clamping wall 31 to maintain the pressing force of the supporting portion 512 on the upper hinge 4.

[0077] See also Figure 6 and Figure 7 The locking lever 52 is rotatably connected to the elastic arm 513. When the abutting portion 512 of the pressing member 51 presses against the upper hinge 4, the locking lever 52 rotates approximately horizontally. As the locking lever 52 rotates, one end of the locking lever 52 engages the engaging wall 31, thereby locking the pressing member 51 above the upper hinge 4. Therefore, the locking lever 52 and the pressing member 51 cooperate to form a two-stage locking structure, effectively preventing the pressing member 51 from accidentally rotating and unlocking.

[0078] In some embodiments, a laterally extending retaining rib 313 is provided on the sidewall of the retaining wall 31 opposite the retaining rib 312. The end of the locking lever 52 rotates to engage the underside of the retaining rib 313, thereby securing the rear end of the pressing member 51 to the retaining wall 31.

[0079] In some embodiments, a rivet portion 514 is protruded from one side of the elastic arm 513 near the engaging wall 31, and the middle portion of the locking rod 52 is rotatably connected to the rivet portion 514 by means of riveting. At this time, the locking rod 52 rotates above the top surface of the elastic arm 513.

[0080] In some embodiments, the locking rod 52 has two ends protruding downwardly extending clips 521. During the rotation of the locking rod 52, the clips 521 can abut against the pressing member 51, thereby limiting the rotation range of the locking rod 52 and facilitating the disassembly and assembly operations.

[0081] See also Figure 1 and Figure 2 The hinge cover 6 is provided at the top of the box body 1 and is used to cover and close 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 in appearance.

Figure 12 yes Figure 11 Schematic diagram of the structure from another perspective.

[0083] See also Figures 8 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, as shown in FIG. Figure 3 Then the upper hinge 4 is mounted on the mounting base 3, as shown Figure 8 Then the pressure rod assembly 5 is mounted on top of the upper hinge 4, as shown Figure 9 and Figure 10 Finally, lock the pressure rod assembly 5 on the mounting seat 3, as shown Figure 11 and Figure 12 shown.

[0084] 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.

[0085] See also Figure 8 When installing the upper hinge 4, the front end of the upper hinge 4 tilts upward, allowing the first raised portion 413 at the rear end of the upper hinge 4 to be inserted and fixed into the slot 311 on the clamping wall 31. The clamping groove 412 of the upper hinge 4 is then aligned with the mounting wall 32, allowing the front end of the upper hinge 4 to be installed downward, so that the upper hinge 4 is clamped between the two mounting walls 32. At this time, the positioning hole 411 on the upper hinge 4 is aligned with the positioning post 33 on the mounting base 3, so that the positioning post 33 is inserted and fixed into 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.

[0086] 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 rod 52 backward and downward to make the supporting portion 512 press the upper hinge 4, as shown. Figure 10 Finally, rotate the locking rod 52 so that the end of the locking rod 52 is engaged with the lower side of the locking rib 313 of the engaging wall 31, as shown. Figure 11 and Figure 12 As shown, at this time, the retaining rib 313 can prevent the locking rod 52 and the pressing member 51 from rotating, thereby maintaining the locking state of the pressing rod assembly 5 and the upper hinge 4.

[0087] When unlocking, the locking rod 52 is rotated in the opposite direction to disengage the locking rod 52 from the retaining rib 313, and the pressing state of the pressing member 51 on the upper hinge 4 is released, 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.

[0088] In addition, in the process of locking or unlocking the pressure rod assembly 5 , the locking rod 52 can extend the operating force arm, thereby saving effort and facilitating disassembly and assembly operations for the operator.

[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 7, which is disposed on the inner top surface of the housing 1, directly below the mounting base 3. The reinforcement plate 7 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 7 is provided with a third fixing hole 71, 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 71, thereby securing the mounting base 3 and the reinforcement plate 7 to the housing 1.

[0094] During the refrigerator assembly process, the position of the reinforcing plate 7 is prone to offset due to processing techniques such as foaming, which can lead to inaccurate positioning of the third fixing hole 71 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 upper hinge mechanism 30 is used to connect the box body 1 and the door body 2. At the same time, in the upper hinge mechanism 30, the mounting base 3 is used to cooperate with the upper hinge 4. The mounting base 3 is arranged at the top of the box body 1, which is convenient for the installation of the upper hinge 4 and can improve the installation strength of the upper hinge 4. At the same time, the upper hinge 4 is detachably connected to the mounting base 3, which is convenient for the disassembly of the upper hinge 4 and the box body 1. There is no need to disassemble and fix it with screws, which is beneficial to 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. All changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
