Hinge and refrigerator comprising the same

Abstract

This utility model provides a hinge and a refrigerator including the same. The hinge includes: a first fixed base; a second fixed base; a transmission assembly; and a buffer assembly, which is mounted on the first fixed base or the second connecting member and extends toward the fifth connecting member. A buffer mating part is provided on the side of the fifth connecting member facing the buffer assembly. The buffer assembly is configured to switch from a non-active state to an active state when the buffer mating part abuts against the buffer end face of the buffer assembly during the closing process of the door. The fifth connecting member is the rod used to cooperate with the buffer assembly to achieve the buffering effect. During opening and closing, the fifth connecting member bears a smaller weight of the door, which helps to ensure the overall strength of the hinge. Mounting the buffer assembly on the first fixed base or the second connecting member increases the buffer stroke of the buffer assembly, enabling it to maintain a better buffering effect even when the door speed changes abruptly, thereby reducing or preventing damage to the refrigerator door and cabinet.

Description

Technical Field

[0001] This utility model relates to the field of refrigerators, and in particular to a hinge and a refrigerator including the hinge. Background Technology

[0002] Refrigerator hinges are currently the most commonly used connecting parts for opening and closing refrigerator doors. To ensure good closure performance between the refrigerator door and the refrigerator body after opening or closing, existing refrigerator hinges typically employ a six-bar linkage mechanism. Inside the six-bar linkage hinge, there is often an additional spring module. Its function is to assist the door in automatically closing when the opening angle of the refrigerator door is less than a certain level, and also to provide a certain sealing force. However, if the hinge only contains a spring structure, the impact when the door closes due to the spring's self-resetting mechanism is relatively large, which can generate noise and, in severe cases, damage the door. Therefore, a buffer module is generally needed to ensure that the door closes slowly and evenly when forcefully closed by the user or when the spring automatically closes.

[0003] In existing technologies, a six-bar linkage typically includes a first link member, a second link member, a third link member, a fourth link member, a fifth link member, and a sixth link member. The first link member is fixed to the refrigerator body, and the sixth link member is installed on the refrigerator door. The second, third, fourth, and fifth link members are drive-connected between the first and sixth link members, forming a transmission assembly that is drive-connected between the first and sixth link members. The first link member is hinged to the second link member through the first hinge hole, and to the third link member through the second hinge hole. The second link member is also hinged to the fourth link member through the third hinge hole. The third link member is also hinged to the fourth link member through the fourth hinge hole, and to the fifth link member through the fifth hinge hole. The fourth link member is also hinged to the sixth link member through the seventh hinge hole, and the fifth link member is also hinged to the sixth link member through the sixth hinge hole. The first link member can also be referred to as the first fixed seat, and its position relative to the housing is fixed. The sixth link member can also be referred to as the second fixed seat, and its position relative to the door is fixed. The transmission assembly is configured to, during the closing process of the door, drive the second fixed seat (i.e., the sixth transmission rod) to fold towards the first fixed seat (i.e., the first transmission rod) and embed it into the first fixed seat.

[0004] Chinese patent CN202120208627.1 (authorization announcement number CN214943413U) describes a damping hinge with a buffer function, but the structure has certain shortcomings.

[0005] The main drawbacks of existing technologies are as follows:

[0006] Disadvantage 1: In this patent, the damping buffer is mounted on a fixed base (corresponding to the first linkage member mentioned above). Its function mainly relies on the rod that bears the greatest weight of the door during opening and closing (corresponding to the third linkage member mentioned above). When the hinge is about to close, this rod pushes against the damping buffer placed in the upper left corner to achieve the buffering function. However, in this hinge structure, this rod has a significant weak point. If the damping function is still achieved by the collision between this rod and the damping buffer, the strength of this rod is questionable.

[0007] Disadvantage 2: Due to space constraints, the damping size used in this structure is small and the stroke is short. During use, there are sudden changes in the door speed, which cannot achieve a linear or near-linear buffering effect during the closing process. The buffering effect is poor and it is easy to damage the refrigerator door and cabinet. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the defect that the refrigerator door is easily damaged when the speed changes suddenly during closing, and to provide a hinge and a refrigerator including the hinge.

[0009] The present invention solves the above-mentioned technical problems through the following technical solution:

[0010] A hinge for opening and closing a refrigerator door, the hinge being a six-bar linkage and comprising:

[0011] A first fixing bracket is used for mounting on the refrigerator body;

[0012] The second fixing seat is used for installation on the door body;

[0013] A transmission assembly is tractively connected between the first fixed seat and the second fixed seat, and the transmission assembly includes a second link member, a third link member, a fourth link member, and a fifth link member;

[0014] The hinge also includes a buffer assembly, which is mounted on the first fixed base or the second link member and extends toward the fifth link member;

[0015] The fifth link member has a buffer mating part on the side facing the buffer assembly. The buffer assembly has an active state where the buffering function is activated and an inactive state where the buffering function is not activated. The buffer assembly is configured to switch from the inactive state to the active state when the buffer mating part abuts against the buffer end face of the buffer assembly during the closing process of the door.

[0016] In this solution, the aforementioned structural configuration, compared to existing technologies, improves the linkage used to achieve the buffering effect from the third linkage member to the fifth linkage member. During opening and closing, the weight of the door body borne by the fifth linkage member is significantly less than that borne by the third linkage member, which helps ensure the overall strength of the hinge. Furthermore, mounting the buffer assembly on the first fixed base or the second linkage member increases the buffer stroke of the buffer assembly, ensuring a better buffering effect even when the door speed changes abruptly, thereby reducing or preventing damage to the refrigerator door and cabinet.

[0017] Preferably, the first end of the fifth link member is hinged to the second fixed seat, the second end of the fifth link member is hinged to the third link member, and the buffer mating part is disposed at the second end of the fifth link member and extends from the second end of the fifth link member toward the buffer assembly.

[0018] In this design, the buffer engagement is located at the end of the fifth link member that hinges to the third link member. This allows for timely contact with the buffer assembly during door closing, minimizing interference with other hinge structures and ensuring proper hinge operation. Furthermore, by positioning the buffer engagement as an extension of the second end of the fifth link member towards the buffer assembly, the strength of the fifth link member is not compromised, and earlier contact with the buffer assembly facilitates a larger buffer stroke, further enhancing the buffering effect.

[0019] Preferably, the shape of the mating surface of the buffer mating part that mates with the buffer end face is adapted to the shape of the buffer end face, so that when the buffer mating part abuts against the buffer end face, the mating surface can fit snugly against the buffer end face.

[0020] In this solution, the above-mentioned structural configuration is adopted, and the shape of the mating surface is adapted to the shape of the buffer end face. The mating surface and the buffer end face fit together, so that the mating surface and the buffer end face have a large contact area. After the mating surface and the buffer end face come into contact, they are not easy to separate, which helps to further ensure the buffering effect.

[0021] Preferably, the mating surface is an inclined surface.

[0022] In this solution, the above-mentioned structural design can achieve a larger contact area within an effective space, which is conducive to further ensuring the buffering effect.

[0023] Preferably, the buffer assembly has a first end and a second end along the buffering direction, the first end of the buffer assembly is mounted on the first fixed base, the second end of the buffer assembly is a free end, and the buffer end face is the end face of the second end of the buffer assembly;

[0024] The second connecting rod member has a receiving groove on the side near the first fixed seat, and the second end of the buffer assembly can extend into the receiving groove and at least the buffer end face can extend out of the receiving groove.

[0025] In this design, the second link member has a receiving groove on the side near the first fixed seat. This groove accommodates and avoids the buffer assembly, allowing it to abut against the buffer mating part on the fifth link member. This arrangement improves space utilization, makes the hinge more compact and stable, and allows the buffer assembly to have a larger buffer stroke within a limited space. Furthermore, the receiving groove helps prevent the buffer member from tilting or wobbling, thus preventing it from affecting the buffering function and further ensuring the buffering effect.

[0026] Preferably, the buffer assembly has a buffer rod and a buffer sleeved on the second end of the buffer rod, the first fixing seat has a mounting hole, and the first end of the buffer rod passes through the mounting hole and is fixed to the first fixing seat;

[0027] The end face of the buffer is the buffer end face.

[0028] In this design, the method of fixing the first end of the buffer rod through the mounting hole and to the first fixed base is relatively stable, making it difficult for the buffer assembly to fall off the first fixed base. Furthermore, the buffer rod is typically lightweight, so it does not place a significant load on the first fixed base. Additionally, the buffer rod's placement through the mounting hole prevents the buffer component from swaying, thus preventing any impact on the buffering effect of the buffer assembly.

[0029] Preferably, the buffer assembly further includes a limiting member, and the mounting hole includes a first mounting hole and a second mounting hole in sequence along the buffer direction. The radius of the second mounting hole is larger than the radius of the first mounting hole. The first mounting hole and the second mounting hole are connected and have a stepped portion at the connection point.

[0030] The limiting member is disposed on the stepped portion and sleeved on the first end of the buffer rod to restrict the movement of the first end of the buffer rod along the buffering direction.

[0031] In this design, the stepped portion ensures the limiting member is securely placed on the first fixed base, preventing it from easily detaching. Furthermore, the limiting member further cushions the buffer rod, preventing a rigid connection between the buffer rod and the first fixed base. This enhances the cushioning effect on the refrigerator door while avoiding direct collisions that could damage both the buffer rod and the first fixed base. The radius of the second mounting hole is larger than that of the first mounting hole, ensuring the limiting member is securely placed on the first fixed base while minimizing the buffer rod's radial space within the first mounting hole. This prevents the buffer member from swaying and maintains the cushioning effect of the buffer assembly.

[0032] Preferably, the number of buffer components and buffer mating parts are both multiple and spaced apart, with each of the multiple buffer components and multiple buffer mating parts corresponding to one another.

[0033] In this design, multiple buffer components and multiple buffer mating parts are set up, with multiple buffering positions, which further improves the buffering effect. In addition, the multiple buffer components are set at intervals, and the buffering positions are relatively dispersed. Therefore, when the buffer components buffer the refrigerator door, the force on the buffer components is also relatively dispersed, which helps to prevent the impact force of the refrigerator door on the refrigerator body from being too concentrated, and helps to protect the refrigerator body and door.

[0034] Preferably, the plurality of said buffer components are spaced apart in the horizontal direction.

[0035] In this scheme, the above-mentioned structural arrangement is adopted, with multiple buffer components spaced apart in the horizontal direction. This arrangement makes more effective use of the space below the first fixed seat and is more compatible with the movement process of the fifth link component, which is conducive to achieving linear buffering.

[0036] This utility model also provides a refrigerator, which includes a cabinet and a door, and the refrigerator also includes the aforementioned hinge.

[0037] In this design, since the fifth link member is used in the hinge to cooperate with the buffer assembly to achieve the buffering effect, the weight of the door body carried by the fifth link member during opening and closing is relatively small, which helps to ensure the overall strength of the hinge. In addition, installing the buffer assembly on the first fixed base or the second link member helps to increase the buffering stroke of the buffer assembly, which can still have a better buffering effect when the door speed changes suddenly, thereby reducing or avoiding damage to the refrigerator door and cabinet.

[0038] The positive and progressive effects of this utility model are as follows:

[0039] In this application, compared to the prior art, the rod used to cooperate with the buffer assembly to achieve the buffering effect is improved from the third link member to the fifth link member. During the opening and closing process, the weight of the door body borne by the fifth link member is much less than that borne by the third link member, which helps to ensure the overall strength of the hinge. In addition, the buffer assembly is installed on the first fixed base or the second link member, which helps to increase the buffering stroke of the buffer assembly, so that it can still have a better buffering effect when the speed of the door changes suddenly, thereby reducing or avoiding damage to the refrigerator door and cabinet.

[0071] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments, but the present invention is not limited to the scope of the embodiments thereon.

[0072] like Figures 1 to 12As shown, this embodiment provides a hinge and a refrigerator including the hinge. Besides the hinge, the refrigerator also includes a cabinet (not shown) and a door (not shown). The hinge is used to open and close the refrigerator door. Specifically, the hinge is a six-bar linkage and includes a first fixed base 10, a second fixed base 20, a transmission assembly, and a buffer assembly 70. The first fixed base 10 is used to mount on the refrigerator cabinet, the second fixed base 20 is used to mount on the door, and the transmission assembly is drivingly connected between the first fixed base 10 and the second fixed base 20. The transmission assembly includes a second link member 30, a third link member 40, a fourth link member 50, and a fifth link member 60. The buffer assembly 70 is mounted on the first fixed base 10 or the second link member 30 and extends toward the fifth link member 60. Among them, the fifth link member 60 is provided with a buffer mating part 601 on the side facing the buffer assembly 70. The buffer assembly 70 has an active state in which the buffering function is activated and an inactive state in which the buffering function is not activated. The buffer assembly 70 is configured to switch from the inactive state to the active state when the buffer mating part 601 abuts against the buffer end face 701 of the buffer assembly 70 during the closing process of the door.

[0073] In this embodiment, using the above-described structural configuration, compared to the prior art, the rod used to cooperate with the buffer assembly 70 to achieve the buffering effect is improved from the third link member 40 to the fifth link member 60. During the opening and closing process, the weight of the door body carried by the fifth link member 60 is much less than the weight of the door body carried by the third link member 40, which helps to ensure the overall strength of the hinge. In addition, the buffer assembly 70 is installed on the first fixed base 10 or the second link member 30, which helps to increase the buffering stroke of the buffer assembly 70, so that it can still have a better buffering effect when the speed of the door changes suddenly, thereby reducing or avoiding damage to the refrigerator door and cabinet.

[0074] When the door is open, the buffer mating part 601 and the buffer end face 701 of the buffer assembly 70 are separated and far apart, so the buffer assembly 70 does not function. During the closing process, the fifth link member 60 moves. During this movement, the distance between the buffer mating part 601 and the buffer end face 701 of the buffer assembly 70 changes. When the buffer mating part 601 and the buffer end face 701 of the buffer assembly 70 come into contact, the buffer assembly 70 performs its buffering function until the door is closed.

[0075] like Figures 2 to 4 , Figures 8 to 10 As shown, the first end of the fifth link member 60 is hinged to the second fixed seat 20, the second end of the fifth link member 60 is hinged to the third link member 40, and the buffer mating part 601 is provided at the second end of the fifth link member 60 and extends from the second end of the fifth link member 60 toward the buffer assembly 70.

[0076] The buffer engagement part 601 is located at the end of the fifth link member 60 that is hinged to the third link member 40. During the door closing process, it can promptly contact the buffer assembly 70 without easily interfering with other structures of the hinge, thus ensuring the normal operation of the hinge. Furthermore, setting the buffer engagement so that the second end of the fifth link member 60 extends towards the buffer assembly 70 avoids affecting the strength of the fifth link member 60 itself and allows for earlier contact with the buffer assembly 70, facilitating a larger buffer stroke and further ensuring a better buffering effect.

[0077] In this embodiment, as a preferred configuration, the buffer mating part 601 is integrally formed with the fifth link member 60. In other alternative embodiments, the buffer mating part 601 may also be separately connected to the fifth link member 60.

[0078] It should be noted that the specific shape and specifications of the buffer mating part 601 are not limited here, as long as they can meet the corresponding setting requirements and achieve the corresponding buffering effect.

[0079] As a preferred configuration, the shape of the mating surface of the buffer mating part 601 that mates with the buffer end face 701 is adapted to the shape of the buffer end face 701, so that when the buffer mating part 601 abuts against the buffer end face 701, the mating surface can fit snugly against the buffer end face 701.

[0080] With this configuration, the shape of the mating surface matches the shape of the buffer end face 701, and the mating surface fits snugly against the buffer end face 701, resulting in a large contact area between the mating surface and the buffer end face 701. After the mating surface and the buffer end face 701 come into contact, they are not easily separated, which helps to further ensure the buffering effect.

[0081] like Figures 2 to 4 , Figures 7 to 10 As shown, the mating surface is inclined, and correspondingly, the buffer end face 701 is also inclined. This design allows for a larger contact area within the available space, thus further ensuring the buffering effect.

[0082] like Figures 1 to 7 , Figures 9 to 12 As shown, the buffer assembly 70 has a first end and a second end along the buffering direction. The first end of the buffer assembly 70 is mounted on the first fixed base 10, and the second end of the buffer assembly 70 is a free end. The buffer end face 701 is the end face of the second end of the buffer assembly 70. The second connecting rod member 30 has a receiving groove 301 on the side near the first fixed base 10. The second end of the buffer assembly 70 can extend into the receiving groove 301, and at least the buffer end face 701 can extend out of the receiving groove 301.

[0083] Here, the second link member 30 is provided with a receiving groove 301 on the side near the first fixed seat 10. The receiving groove 301 is used to receive and avoid the buffer assembly 70, so that the buffer assembly 70 can abut against the buffer mating part 601 on the fifth link member 60. The above arrangement is conducive to improving space utilization, making the hinge more compact and stable, and enabling the buffer assembly 70 to have a large buffer stroke within a limited space. In addition, the receiving groove 301 helps to prevent the buffer member from tilting or shaking and affecting the buffering function of the buffer assembly 70, thereby further ensuring the buffering effect.

[0084] It should be noted that the specific structure of the buffer component 70 is not limited; it can adopt a structure known in the prior art, as long as it can be used in the hinge to play a buffering role, at least as... Figure 7 , Figures 9 to 12 As shown, the buffer assembly 70 has a buffer rod 702 and a buffer 703 sleeved on the second end of the buffer rod 702. The first fixing base 10 has a mounting hole 101. The first end of the buffer rod 702 passes through the mounting hole 101 and is fixed to the first fixing base 10. The end face of the buffer 703 is the buffer end face 701.

[0085] The method of fixing the first end of the buffer rod 702 through the mounting hole 101 and to the first fixed base 10 is relatively stable, making it difficult for the buffer assembly 70 to fall off the first fixed base 10. The buffer rod 702 is typically lightweight and will not place a significant load on the first fixed base 10. Furthermore, the buffer rod 702 passing through the mounting hole 101 prevents the buffer component from swaying and thus avoids affecting the buffering effect of the buffer assembly 70.

[0086] During the closing process of the door, when the fifth link member 60 moves to the point where the buffer mating part 601 abuts against the end face of the buffer 703, the fifth link member 60 pushes the buffer 703 to move relative to the buffer rod 702 to achieve buffering.

[0087] Furthermore, at least as Figure 6 and Figure 7 As shown, the buffer assembly 70 also includes a limiting member 704. The mounting hole 101 includes a first mounting hole 1011 and a second mounting hole 1012 along the buffering direction. The radius of the second mounting hole 1012 is larger than the radius of the first mounting hole 1011. The first mounting hole 1011 and the second mounting hole 1012 are connected and have a stepped portion at the connection. The limiting member 704 is disposed on the stepped portion and is sleeved on the first end of the buffer rod 702 to restrict the movement of the first end of the buffer rod 702 along the buffering direction.

[0088] In this embodiment, the step portion allows the limiting member 704 to be securely placed on the first fixed base 10, preventing it from easily detaching. Furthermore, the limiting member 704 further cushions the buffer rod 702, preventing a rigid connection between the buffer rod 702 and the first fixed base 10. This improves the cushioning effect on the refrigerator door while avoiding direct collision between the buffer rod 702 and the first fixed base 10, which could damage both. The radius of the second mounting hole 1012 is larger than the radius of the first mounting hole 1011, ensuring the limiting member 704 is securely placed on the first fixed base 10. It also limits the free space of the buffer rod 702 in the radial direction of the first mounting hole 1011, preventing the buffer member from swaying and affecting the cushioning effect of the buffer assembly 70.

[0089] At least as Figures 1 to 7 As shown, a spring module 80 is provided inside the second link member 30. The spring module 80 is used to cooperate with the mating structure 90 on the fourth link member 50 to assist the door in automatically closing when the opening angle of the refrigerator door is less than a certain degree.

[0090] In a preferred configuration, to further improve the buffering effect, the number of buffer components 70 and buffer mating parts 601 can be set to multiple, spaced apart, with multiple buffer components 70 and multiple buffer mating parts 601 arranged in a one-to-one correspondence.

[0091] The refrigerator features multiple buffer components 70 and multiple buffer mating parts 601, providing multiple buffering positions to further enhance the buffering effect. Furthermore, the multiple buffer components 70 are spaced apart, resulting in a more dispersed buffering position. Therefore, when the buffer components 70 buffer the refrigerator door, the force on each component is also more dispersed, which helps prevent the impact force from the refrigerator door on the refrigerator body from being too concentrated, thus protecting both the refrigerator body and the door.

[0092] Furthermore, the multiple buffer components 70 can be arranged at intervals along the horizontal direction. This arrangement of multiple buffer components 70 at intervals along the horizontal direction makes more efficient use of the space below the first fixed base 10 and is better suited to the movement of the fifth link member 60, thus facilitating linear buffering.

[0093] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
