Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, for example, to a hinge assembly and a refrigerator. Background Art

[0002] At present, the door of a refrigerator is connected to the refrigerator body through a hinge or hinge assembly, so that the door and the body can be rotated to open or close. In the process of opening the door, after the user opens the door and releases the grip on the door, the door will continue to rotate for a distance under the action of inertia, making it easy for the door to collide with external objects such as walls and cabinets, resulting in a high risk of bumping the door.

[0003] In the related art, there is a hinge for a refrigerator and a refrigerator. The refrigerator includes a box body, a main door, a sub-door and a hinge plate. The hinge plate is arranged on the box body. The hinge plate includes a rotational matching portion. The main door is rotationally connected to the box body. The hinge includes: a hinge body, one end of which is configured with a rotational portion. The rotational portion is suitable for rotationally connecting with the rotational matching portion so that the hinge rotates around the rotational matching portion. The other end of the hinge body is suitable for connecting with the sub-door so that the sub-door rotates around the rotational matching portion with the hinge; a stopper, which is arranged on one side of the hinge body. The hinge body and the stopper are arranged in sequence along the direction of opening of the sub-door. When the sub-door is opened to a preset angle, the stopper can abut against the hinge plate to limit the rotation of the hinge. The stopper cooperates with the hinge plate to limit the maximum angle of inertial rotation of the door body, thereby reducing the risk of damage to the door body due to collision.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] The maximum opening angle of the door is fixed and difficult to adjust.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0008] The disclosed embodiments provide a hinge assembly and a refrigerator to adjust the maximum opening angle of a door.

The shaft sleeve is provided with an insertion hole and a limiting groove, the hinge shaft can be limited to rotate in the insertion hole, and the limiting groove includes an initial surface and a limiting surface; the adjustment assembly is sleeved on the hinge shaft and has a damping force relative to the rotation between the hinge shafts, and a part of the adjustment assembly extends into the limiting groove and is limited to move between the initial surface and the limiting surface of the limiting groove; wherein, the angle of the part of the adjustment assembly extending into the limiting groove from abutting against the initial surface to abutting against the limiting surface is the maximum opening angle of the door body.

[0010] Optionally, the adjustment assembly includes: an adjustment block and a connecting ring. The adjustment block is sleeved on the hinge shaft and has a damping force relative to the rotation between the hinge shafts; the connecting ring is movably sleeved on the hinge shaft and fixedly connected to the adjustment block, and a limiting protrusion is provided on the connecting ring, which is limited to move between the initial surface and the limiting surface of the limiting groove.

[0011] Optionally, the limiting groove includes: a fixed groove and a fan-shaped groove. The fixed groove is coaxially arranged with the plug hole, and the connecting ring can be adapted to be arranged to rotate in the fixed groove; the fan-shaped groove extends outward from the inner side wall of the fixed groove, and an initial surface and a limiting surface are provided on the fan-shaped groove, and the limiting protrusion is limited to move between the initial surface and the limiting surface of the limiting groove.

[0012] Optionally, the fixing groove and the fan-shaped groove are arranged cocentrically.

[0013] Optionally, the shaft sleeve includes: a sleeve and a limiting ring. The limiting ring is arranged at one end of the sleeve and is coaxial with the sleeve; wherein the plug hole passes through the limiting ring and extends to the inside of the sleeve, and the limiting groove is arranged on the limiting ring.

[0014] Optionally, the diameter of the limiting ring is greater than the diameter of the sleeve.

[0015] Optionally, the diameter of one end of the hinge shaft inserted into the plug hole gradually decreases, and the diameter of the plug hole also gradually decreases adaptively.

[0016] Optionally, part of the adjustment component is connected to the hinge shaft via a thread, so that the rotation of the adjustment component relative to the hinge shaft has a damping force.

In the process of opening the door body, since the rotation between the hinge shaft and the adjustment component has a damping force, the rotation of the hinge shaft drives the adjustment component to rotate, and the part of the adjustment component extending into the limit groove rotates from the initial surface to the limit surface. In the case where the adjustment component turns to the limit surface and abuts against the limit surface, the damping force and the limit surface cooperate to provide a reaction force for the adjustment component to continue to rotate, thereby limiting the adjustment component, the hinge shaft and the door body from continuing to rotate. In the case where the door body is covered on the box body, the adjustment component is rotated on the hinge shaft to adjust the relative angle between the adjustment component and the hinge shaft, and the rotatable angle between the part of the adjustment component extending into the limit groove and the limit surface, thereby adjusting the maximum door opening angle of the door body. The user can adjust the maximum door opening angle of the door body at any time according to the placement position of the refrigerator, thereby reducing the risk of collision between the door body and external objects.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0040] Combination Figure 1-2 As shown, the embodiment of the present disclosure provides a hinge assembly, including: a hinge shaft 100, a sleeve 200 and an adjustment assembly 300. The sleeve 200 is provided with an insertion hole 210 and a limiting groove 220, and the hinge shaft 100 can be limited to rotate in the insertion hole 210, and the limiting groove 220 includes an initial surface 221 and a limiting surface 222; the adjustment assembly 300 is sleeved on the hinge shaft 100, and has a damping force relative to the rotation between the hinge shaft 100, and a part of the adjustment assembly 300 extends into the limiting groove 220, and is limited to move between the initial surface 221 and the limiting surface 222 of the limiting groove 220; wherein, the angle of the part of the adjustment assembly 300 extending into the limiting groove 220 from abutting against the initial surface 221 to abutting against the limiting surface 222 is the maximum opening angle of the door body.

[0041] With the hinge assembly provided in the embodiment of the present disclosure, the refrigerator body and the refrigerator door body are connected through the hinge shaft 100 and the shaft sleeve 200, and the shaft sleeve 200 is provided with a plug hole 210, and the hinge shaft 100 can be limited to rotate in the plug hole 210, so that the door body can be rotated and opened on the box body. In the process of opening the door body, since the rotation between the hinge shaft 100 and the adjustment assembly 300 has a damping force, the rotation of the hinge shaft 100 drives the adjustment assembly 300 to rotate, and the part of the adjustment assembly 300 extending into the limiting groove 220 rotates from the initial surface 221 to the limiting surface 222. When the adjustment assembly 300 turns to the limiting surface 222 and abuts against the limiting surface 222, the damping force and the limiting surface 222 cooperate to provide a reaction force for the adjustment assembly 300 to continue to rotate, thereby limiting the adjustment assembly 300, the hinge shaft 100 and the door body from continuing to rotate. When the door is covered on the box body, the adjustment component 300 is rotated on the hinge shaft 100 to adjust the relative angle between the adjustment component 300 and the hinge shaft 100, as well as the rotatable angle between the part of the adjustment component 300 extending into the limiting groove 220 and the limiting surface 222, thereby adjusting the maximum opening angle of the door. The user can adjust the maximum opening angle of the door at any time according to the placement of the refrigerator to reduce the risk of collision between the door and external objects.

[0042] It can be understood that the damping force of the rotation of the adjustment component 300 relative to the hinge shaft 100 means that the rotation between the adjustment component 300 and the hinge shaft 100 needs to overcome a certain resistance.

[0043] Optionally, the angle between the initial surface 221 and the limiting surface 222 is less than or equal to 270 degrees, and greater than or equal to 60 degrees. In this way, when the angle between the initial surface 221 and the limiting surface 222 is greater than 270 degrees, the angle at which the door body and the box body are opened is too large, and the risk of collision and interference between the door body and the box body after the door body is fully opened is relatively large. When the angle between the initial surface 221 and the limiting surface 222 is less than 60 degrees, the angle at which the door body is opened is too small, and the risk of interference between the door body and the items in the box body is relatively large, which reduces the user experience. It can be seen that the angle between the initial surface 221 and the limiting surface 222 is less than or equal to 270 degrees, and greater than or equal to 60 degrees is more reasonable, the risk of collision and interference between the door body and the box body after the door body is fully opened is relatively small, and the angle at which the door body is opened is relatively large, which reduces the risk of interference between the door body and the items in the box body, and improves the user experience.

[0044] Specifically, the angle between the initial surface 221 and the limiting surface 222 is equal to 180 degrees. In this way, the risk of the door body colliding and interfering with the box body after being fully opened is relatively small, and the angle at which the door body is opened is relatively large, which reduces the risk of the door body interfering with the user's access to the items in the box body and improves the user experience.

[0045] The hinge shaft 100 is coaxial with the insertion hole 210. When the door is opened or closed on the box body, since the hinge shaft 100 rotates coaxially with the insertion hole 210, the risk of the door body deviating during the rotation process is low.

[0046] Optionally, the hinge shaft 100, the shaft sleeve 200 and the adjusting assembly 300 are all made of stainless steel. In this way, the hinge shaft 100, the shaft sleeve 200 and the adjusting assembly 300 made of stainless steel have good oxidation resistance and high durability.

[0047] Combination Figure 3 As shown, optionally, the hinge shaft 100 includes: a rotating shaft 110 and a limiting plate 120. The limiting plate 120 is provided at one end of the rotating shaft 110, and the rotating shaft 110 and the limiting plate 120 are arranged coaxially, and the rotating shaft 110 can be limited to rotate in the plug hole 210, and the adjustment component 300 is sleeved on the rotating shaft 110. In this way, when the rotating shaft 110 is plugged into the plug hole 210, the limiting plate 120 limits the adjustment component 300, thereby reducing the risk of the adjustment component 300 falling off the rotating shaft 110.

[0048] Optionally, the adjustment component 300 is located between the limiting plate 120 and the sleeve 200. In this way, when the rotating shaft 110 is inserted into the insertion hole 210, the limiting plate 120 and the sleeve 200 jointly limit the adjustment component 300, reducing the risk of the adjustment component 300 falling off the rotating shaft 110.

[0049] Optionally, the diameter of the rotating shaft 110 is smaller than the diameter of the limiting plate 120. In this way, the diameter of the limiting plate 120 is larger than the diameter of the rotating shaft 110, and the side wall of the limiting plate 120 along the horizontal direction protrudes from the side wall of the rotating shaft 110 along the horizontal direction, thereby increasing the area of ​​the limiting plate 120 to limit and block the adjustment component 300, and reducing the risk of the adjustment component 300 falling off the rotating shaft 110.

[0050] Combination Figure 4 As shown, optionally, the adjustment assembly 300 includes: an adjustment block 310 and a connecting ring 320. The adjustment block 310 is sleeved on the hinge shaft 100 and has a damping force relative to the rotation between the hinge shaft 100; the connecting ring 320 is movably sleeved on the hinge shaft 100 and fixedly connected to the adjustment block 310, and a limiting protrusion 330 is provided on the connecting ring 320, which is limited to move between the initial surface 221 and the limiting surface 222 of the limiting groove 220. In this way, the adjustment block 310 is rotated on the hinge shaft 100, thereby changing the angle of the adjustment block 310, the connecting ring 320 and the limiting protrusion 330 relative to the hinge shaft 100, and changing the angle of the limiting protrusion 330 relative to the limiting surface 222, thereby adjusting the maximum opening angle of the door body. The user can adjust the maximum opening angle of the door body at any time according to the placement position of the refrigerator, thereby reducing the risk of collision between the door body and external objects.

[0051] Optionally, the diameter of the adjustment block 310 is larger than the diameter of the connecting ring 320. In this way, the diameter of the adjustment block 310 is relatively large, and when the user operates the adjustment block 310 to rotate on the hinge shaft 100, the adjustment block 310 is easier to be clamped, which is convenient for operation.

[0052] Optionally, the limiting protrusion 330 is fixedly connected to the adjustment block 310. In this way, the limiting protrusion 330 is connected to both the connecting ring 320 and the adjustment block 310, and the connection strength is relatively high, reducing the risk of deformation or breakage of the limiting protrusion 330 during the collision with the limiting surface 222 or the initial surface 221.

[0053] Specifically, the limiting protrusion 330 protrudes outward from the outer side wall of the connecting ring 320 along a direction perpendicular to the axis of the connecting ring 320 .

[0054] Optionally, the length of the limiting protrusion 330 in the vertical direction is equal to the length of the connecting ring 320 in the vertical direction. In this way, the area where the limiting protrusion 330 is connected to the connecting ring 320 is relatively large, reducing the risk of deformation or breakage of the limiting protrusion 330 during the collision with the limiting surface 222 or the initial surface 221.

[0055] Optionally, the connecting ring 320 is a circular ring structure. In this way, the outer wall of the connecting ring 320 is relatively smooth, reducing the friction resistance of the connecting ring 320 rotating in the limiting groove 220, so that the force required for the door body to open or close the door is small, thereby improving the user experience.

[0056] Combination Figure 5 As shown, optionally, an adjustment handle 311 is provided on the adjustment block 310. In this way, the user can directly rotate the adjustment block 310 through the adjustment handle 311, which is more convenient and labor-saving to adjust.

[0057] Combination Figure 6 As shown, optionally, the limiting groove 220 includes: a fixing groove 223 and a fan-shaped groove 224. The fixing groove 223 is coaxially arranged with the plug hole 210, and the connecting ring 320 can be adapted to be arranged in the fixing groove 223 for rotation; the fan-shaped groove 224 extends outward from the inner side wall of the fixing groove 223, and the fan-shaped groove 224 is provided with an initial surface 221 and a limiting surface 222, and the limiting protrusion 330 is limited to move between the initial surface 221 and the limiting surface 222 of the limiting groove 220. In this way, during the process of opening or closing the door body, the limiting protrusion 330 rotates with the connecting ring 320 and moves in the fan-shaped groove 224, and the maximum opening angle of the door body is controlled by the cooperation between the limiting protrusion 330 and the initial surface 221 and the limiting surface 222 on the fan-shaped groove 224; the connecting ring 320 rotates in the fixed groove 223, and the fixed groove 223 provides a rotation limit for the connecting ring 320, thereby improving the rotation stability of the connecting ring 320 and the limiting protrusion 330.

[0058] Optionally, the fixing groove 223 is arranged at the edge of the plug hole 210, and an inclined guide surface 230 is arranged at the intersection of the fixing groove 223 and the plug hole 210. In this way, the inclined guide surface 230 provides guidance for the hinge shaft 100 to be inserted into the plug hole 210, thereby reducing the difficulty of installation and improving the assembly efficiency between the hinge shaft 100 and the plug hole 210.

[0059] Optionally, the fixing groove 223 is a circular groove structure. In this way, the shape of the fixing groove 223 corresponds to the shape of the connecting ring 320, so that the fixing groove 223 is better adapted to the connecting ring 320.

[0060] Optionally, the length of the connecting ring 320 in the vertical direction is greater than or equal to twice the depth of the fixing groove 223, and less than or equal to five times the depth of the fixing groove 223. In this way, when the length of the connecting ring 320 in the vertical direction is less than twice the depth of the fixing groove 223, the length of the connecting ring 320 in the vertical direction is short, and the diameter of the adjustment block 310 is greater than the diameter of the connecting ring 320. When the user adjusts the maximum door opening angle, the risk of the adjustment block 310 blocking the user's line of sight is greater, which reduces the efficiency of adjustment. When the length of the connecting ring 320 in the vertical direction is greater than five times the depth of the fixing groove 223, the length of the connecting ring 320 in the vertical direction is too long, which will cause the overall length of the hinge assembly to be too long, and too much space will be occupied on the refrigerator. It can be seen that the range in which the length of the connecting ring 320 in the vertical direction is greater than or equal to twice the depth of the fixing groove 223 and less than or equal to five times the depth of the fixing groove 223 is more reasonable, which reduces the risk of the adjustment block 310 blocking the user's line of sight and does not occupy too much space on the refrigerator.

[0061] Specifically, the length of the connecting ring 320 in the vertical direction is equal to three times the depth of the fixing groove 223. In this way, the risk of the adjusting block 310 blocking the user's sight can be reduced, and too much space on the refrigerator will not be occupied.

[0062] Optionally, the fixing groove 223 is cocentrically arranged with the fan-shaped groove 224. In this way, when the hinge shaft 100 rotates in the plug hole 210, the area of ​​the limiting protrusion 330 in contact with the limiting surface 222 or the initial surface 221 is increased.

[0063] Optionally, the sleeve 200 includes: a sleeve 240 and a limiting ring 250. The limiting ring 250 is arranged at one end of the sleeve 240 and is coaxial with the sleeve 240; wherein the plug hole 210 passes through the limiting ring 250 and extends to the inside of the sleeve 240, and the limiting groove 220 is arranged on the limiting ring 250. In this way, the hinge shaft 100 is inserted into the plug hole 210, and the adjustment component moves in the limiting groove 220. Since the limiting ring 250 is coaxially arranged with the sleeve 240, the stability of the hinge shaft 100 rotating in the plug hole 210 and the adjustment component moving in the limiting groove 220 is relatively high.

[0064] Optionally, the sleeve 240 can be inserted into the installation tube, and the installation tube is used to be fixed at its installation position. The outer wall of the sleeve 240 is provided with a convex strip 241, and the inner wall of the installation tube is correspondingly provided with a groove. In this way, the sleeve 240 can be pulled out of the installation tube, and the sleeve 240 can be quickly disassembled for replacement or maintenance, and the convex strip 241 cooperates with the groove to prevent the sleeve 240 and the installation tube from rotating relative to each other. For example, when the sleeve 240 is installed on the door body, the convex strip 241 increases the rotation resistance between the sleeve 240 and the refrigerator, and reduces the risk of the sleeve 240 rotating relative to the door body during the process of opening or closing the door.

[0065] Specifically, the convex strip 241 is arranged in the vertical direction. In this way, the rotation resistance provided by the convex strip 241 is relatively large, further reducing the risk of the sleeve 240 rotating relative to the refrigerator.

[0066] Optionally, the diameter of the limiting ring 250 is larger than the diameter of the sleeve 240. In this way, the diameter of the limiting ring 250 is relatively large, which can provide a larger support area, thereby increasing the contact area between the limiting ring 250 and the adjustment component 300, and improving the stability of the adjustment component 300 rotating on the limiting ring 250.

[0067] Optionally, the diameter of the adjustment block 310 is larger than the diameter of the limiting ring 250. In this way, the diameter of the adjustment block 310 is relatively large, and it is relatively convenient for the user to clamp and rotate the adjustment block 310 when adjusting the maximum door opening angle, thereby reducing the risk of the limiting ring 250 interfering with the clamping adjustment block 310.

[0068] Optionally, the diameter of one end of the hinge shaft 100 inserted into the insertion hole 210 is gradually reduced, and the diameter of the insertion hole 210 is also adaptively gradually reduced. In this way, the difficulty of inserting the hinge shaft 100 into the insertion hole 210 is reduced, the assembly efficiency is improved, and the diameter of the insertion hole 210 is also adaptively gradually reduced, so that the hinge shaft 100 has higher stability in rotating in the insertion hole 210.

[0069] Optionally, part of the adjustment component 300 is connected to the hinge shaft 100 through a thread, so that the rotation of the adjustment component 300 relative to the hinge shaft 100 has a damping force. In this way, the adjustment component 300 rotates on the hinge shaft 100 through the thread, thereby adjusting the angle of the adjustment component 300 relative to the hinge shaft 100, and then adjusting the maximum door opening angle.

[0070] Optionally, when the hinge shaft 100 is inserted into the insertion hole 210, there is a gap between the adjustment component 300 and the limiting groove 220 in the vertical direction. In this way, part of the adjustment component 300 is connected to the hinge shaft 100 through a thread, and there is a gap between the adjustment component 300 and the limiting groove 220 in the vertical direction. The adjustment component 300 rotates relative to the hinge shaft 100, and the gap facilitates the adjustment component 300 to move upward along the axis of the hinge shaft 100. In addition, due to the existence of the gap, the hinge shaft 100 no longer provides support force for the adjustment component 300 along its axis.

[0071] Exemplarily, part of the adjustment component 300 can also be connected to the hinge shaft 100 via a damping bearing, so that the rotation of the adjustment component 300 relative to the hinge shaft 100 has a damping force.

[0072] Combination Figure 7 As shown, specifically, the adjustment block 310 includes a nut 312. The nut 312 is connected to the hinge shaft 100 through a thread, so that the rotation between the nut 312 and the hinge shaft 100 has a damping force.

[0073] Combination Figure 8 As shown, optionally, the hinge assembly further includes: a hinge plate 400. One end of the hinge plate 400 is fixedly connected to the end of the hinge shaft 100. In this way, the hinge plate 400 is fixedly connected to the end of the hinge shaft 100, and then installed on the refrigerator through the hinge plate 400. The area of ​​the hinge plate 400 is relatively large, and the contact area with the refrigerator is large, which improves the stability of the installation.

[0074] Specifically, the hinge plate 400 is fixedly connected to the limiting plate 120. In this way, the hinge plate 400 is fixedly connected to the limiting plate 120, and then installed on the refrigerator through the hinge plate 400. The area of ​​the hinge plate 400 is relatively large, and the contact area with the refrigerator is large, which improves the stability of the installation.

[0075] Optionally, a reinforcing protrusion 410 is provided on the hinge plate 400. Thus, the rigidity of the hinge plate 400 is increased by reinforcing the protrusion 410, and the connection stability of the hinge plate 400 is improved.

[0076] Combination Fig. 9 As shown, in some embodiments, a refrigerator includes a hinge assembly as described in any one of the above embodiments.

[0077] The refrigerator is provided by adopting this embodiment. Since the refrigerator includes a hinge assembly as in any of the above embodiments, the refrigerator body and the refrigerator door body are connected through the hinge shaft 100 and the shaft sleeve 200. The shaft sleeve 200 is provided with a plug hole 210. The hinge shaft 100 can be limited to rotate in the plug hole 210, so that the door body can be rotated and opened on the box body. In the process of opening the door body, since the rotation between the hinge shaft 100 and the adjustment assembly 300 has a damping force, the rotation of the hinge shaft 100 drives the adjustment assembly 300 to rotate, and the part of the adjustment assembly 300 extending into the limiting groove 220 rotates from the initial surface 221 to the limiting surface 222. In the case where the adjustment assembly 300 turns to the limiting surface 222 and abuts against the limiting surface 222, the damping force and the limiting surface 222 cooperate to provide a reaction force for the adjustment assembly 300 to continue to rotate, thereby limiting the adjustment assembly 300, the hinge shaft 100 and the door body from continuing to rotate. When the door is covered on the box body, the adjustment component 300 is rotated on the hinge shaft 100 to adjust the relative angle between the adjustment component 300 and the hinge shaft 100, as well as the rotatable angle between the part of the adjustment component 300 extending into the limiting groove 220 and the limiting surface 222, thereby adjusting the maximum opening angle of the door. The user can adjust the maximum opening angle of the door at any time according to the placement of the refrigerator to reduce the risk of collision between the door and external objects.

[0078] Optionally, the refrigerator includes: a door body and a box body. One of the hinge plate 400 and the shaft sleeve 200 is connected to the door body, and the other is connected to the box body. In this way, the door body is rotated on the box body to open through the hinge assembly, and the maximum opening angle of the door body can be adjusted at any time according to the position of the box body.

[0079] Specifically, the shaft sleeve 200 is connected to the door body, and the hinge plate 400 is connected to the box body.

[0080] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations may vary.
