Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and in particular to a hinge reinforcement assembly for a refrigerator and a refrigerator. Background Art

[0002] At present, refrigerators use hinges to fix the relative position of the refrigerator door and the refrigerator body, so that the refrigerator door can rotate normally. The hinge positioning structure on the refrigerator door usually uses riveted positioning columns to position the hinge on the reinforcing iron on both sides of the refrigerator. However, this positioning method requires high positioning accuracy. If the size of the positioning column on the reinforcing iron is significantly different from the positioning hole on the hinge, the gap between the two will be too large, which may easily cause the hinge to shake.

[0003] In the related art, the positioning tongue on the hinge reinforcement iron is embedded in the positioning slot on the hinge plate to limit the front, back, left and right freedom of the upper hinge, providing a positioning function, and finally the upper hinge is fixed with screws to limit the up and down freedom, which is reliable.

[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 related technology only uses the positioning tongue and the positioning slot to replace the riveted positioning column positioning method to provide accurate positioning between the hinge and the reinforcing iron, but it cannot provide accurate positioning for the relative position between the two hinges. If the relative position of the reinforcing iron fixing holes on both sides of the refrigerator is inaccurate, the relative position of the two hinges will be inconsistent, which may cause the two doors of the refrigerator to be uneven and the gap to be large.

[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.

[0040] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0041] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0042] 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.

[0043] At present, refrigerators use hinges to fix the relative position of the refrigerator door and the refrigerator body, so that the refrigerator door can rotate normally. The hinge positioning structure on the refrigerator door usually uses riveted positioning columns to position the hinge on the reinforcing iron on both sides of the refrigerator. However, the process of riveting the positioning columns on the reinforcing iron is complicated and costly. Three screws are required to fix it, and a large number of screws are used, resulting in cost waste.

[0044] Moreover, this positioning method requires high positioning accuracy. The positioning of the positioning column has high requirements on the size and dimensions of the positioning hole on the hinge. If the size of the positioning column on the reinforcement iron is greatly different from that of the positioning hole, resulting in a large gap between the two, it is easy to cause the hinge to shake, and the requirements for screw fixation are high. In addition, the order of fixing the screws will also cause different degrees of deviation.

[0045] In the spatial rectangular coordinate system, the workpiece has six degrees of freedom, namely, three degrees of freedom to move along the three rectangular coordinate axes of x, y, and z and three degrees of freedom to rotate around these three coordinate axes. Therefore, to completely determine the position of the workpiece, these six degrees of freedom must be eliminated. Usually, six support points are used to limit the six degrees of freedom of the workpiece, and each support point limits a corresponding degree of freedom. If certain constraint measures are taken to eliminate the six degrees of freedom of the object, the object will be completely positioned.

[0046] The hinge cannot completely limit its freedom by a locating column, and the hinge can still rotate around the locating column.

[0047] Moreover, the reinforcement iron currently used is usually a split reinforcement iron that forms a left and right mirror image, or the left and right reinforcement irons are connected into a whole, and the reinforcement iron itself cannot be formed in one piece. The split reinforcement iron cannot control the relative position of the two doors, and the positioning structure on the left and right reinforcement irons has very high positioning requirements. The positioning column on the reinforcement iron and the positioning hole on the hinge are required to be very close in size, such as a 0.1mm gap, requiring the installation operator to align the hole and column to complete the installation. There is even a solution with two positioning columns, which requires higher installation accuracy. Once the through hole of the hinge and the through hole of the reinforcement iron are not accurately positioned, it will lead to a failure to install normally, and the stamping accuracy of both parts is required to be high.

[0048] In the related art, the positioning tongue on the hinge reinforcement iron is embedded in the positioning slot on the hinge plate to limit the front, back, left and right freedom of the upper hinge, providing a positioning function, and finally the upper hinge is fixed with screws to limit the up and down freedom, which is reliable.

[0049] The related technology only uses the positioning tongue and the positioning slot to replace the riveted positioning column positioning method to provide accurate positioning between the hinge and the reinforcing iron, but it cannot provide accurate positioning for the relative position between the two hinges. If the relative position of the reinforcing iron fixing holes on both sides of the refrigerator is inaccurate, the relative position of the two hinges will be inconsistent, which may cause the two doors of the refrigerator to be uneven and the gap to be large.

[0050] Therefore, the embodiment of the present disclosure positions and connects two hinges at relative positions at both ends of the same reinforcement plate to form an integrated hinge reinforcement plate, so that the relative positions of the two hinges are stable and consistent, thereby stabilizing the installation state of the two doors of the refrigerator.

[0051] Combination Figure 1-6 As shown, the embodiment of the present disclosure provides a hinge reinforcement assembly for a refrigerator, including: a reinforcement plate 10, a first hinge 20 and a second hinge 30, wherein a first positioning portion 11 and a second positioning portion 12 are respectively provided at both ends of the reinforcement plate 10 in the length direction; and the first positioning portion 11 and the second positioning portion 12 include at least symmetrical sub-positioning portions 13; the first hinge 20 is provided at one end of the reinforcement plate 10, and is suitable for being positioned at the first positioning portion 11; the second hinge 30 is provided at the other end of the reinforcement plate 10, and is suitable for being positioned at the second positioning portion 12.

[0052] By using the hinge reinforcement assembly for refrigerators provided by the embodiment of the present disclosure, the symmetrical sub-positioning parts 13 arranged at both ends of the same reinforcement plate 10 in the length direction can be formed by one-time molding, thereby improving the consistency of the positions of the symmetrical sub-positioning parts 13. The first positioning part 11 positions the first hinge 20 at one end of the reinforcement plate 10, and the second positioning part 12 positions the second hinge 30 at the other end of the reinforcement plate 10. The symmetrical sub-positioning parts 13 can more accurately limit the first hinge 20 and the second hinge 30 to the symmetrical positions at both ends of the reinforcement plate 10, thereby improving the consistency of the relative positions between the first hinge 20 and the second hinge 30 of the refrigerator.

[0053] Optionally, combined Figure 1-8 As shown, the first positioning portion 11 includes one or more first positioning structures 111, and the first hinge 20 is provided with one or more matching first positioning matching structures 21; the second positioning portion 12 includes one or more second positioning structures 121; the second hinge 30 is provided with one or more matching second positioning matching structures 31; wherein, at least one first positioning structure 111 of the first positioning portion 11 and at least one second positioning structure 121 of the second positioning portion 12 are symmetrically arranged to form a symmetrical sub-positioning portion 13.

[0054] By cooperating a first positioning structure 111 with a first positioning matching structure 21, the first hinge 20 can be positioned at the first positioning portion 11; or, by cooperating a plurality of first positioning structures 111 with a plurality of first positioning matching structures 21, the first hinge 20 can be positioned at the first positioning portion 11. By cooperating a second positioning structure 121 with a second positioning matching structure 31, the second hinge 30 can be positioned at the second positioning portion 12; or, by cooperating a plurality of second positioning structures 121 with a plurality of second positioning matching structures 31, the second hinge 30 can be positioned at the second positioning portion 12.

[0055] The number of the first positioning structures 111 and the number of the second positioning structures 121 may be the same or different. However, at least one first positioning structure 111 and at least one second positioning structure 121 are symmetrically arranged to form a symmetrical sub-positioning portion 13. By arranging symmetrical sub-positioning portions 13 at both ends of the reinforcing plate 10, the symmetrical first hinge 20 and the second hinge 30 are positioned respectively, so that the consistency of the relative position between the first hinge 20 and the second hinge 30 can be improved. The symmetric relationship here includes the symmetry of position, or includes the symmetry of position and the symmetry of structure.

[0056] Before fixing the first hinge 20 or the second hinge 30 on the plane of the reinforcing plate 10, it is necessary to place the first hinge 20 or the second hinge 30 on the surface of the reinforcing plate 10 for positioning. The first positioning portion 11 can accurately position the first hinge 20 by limiting the three degrees of freedom of the first hinge 20: translation along the width direction of the reinforcing plate 10, translation along the length direction of the reinforcing plate 10, and rotation along the direction perpendicular to the plane where the reinforcing plate 10 is located. Similarly, the second positioning portion 12 can also achieve accurate positioning of the second hinge 30 by limiting the above three degrees of freedom of the second hinge 30.

[0057] Optionally, combined Figure 4-8As shown, the symmetrical sub-positioning portion 13 includes a first sub-positioning portion 131 and a second sub-positioning portion 135 that are symmetrically arranged; the number of the first sub-positioning portions 131 is multiple, and the multiple first sub-positioning portions 131 include a first transverse sub-positioning portion 132 and a first longitudinal sub-positioning portion 133, the first transverse sub-positioning portion 132 is arranged at one or more first positioning structures 111, and the first longitudinal sub-positioning portion 133 is arranged at one or more first positioning structures 111; the first hinge 20 is provided with a plurality of first sub-positioning matching portions 22 that match, and the plurality of first sub-positioning matching portions 22 include a first transverse sub-positioning The matching portion 23 and the first longitudinal sub-positioning matching portion 24, the first transverse sub-positioning matching portion 23 and the first transverse sub-positioning matching portion 132 are correspondingly arranged, and the first longitudinal sub-positioning matching portion 24 and the first longitudinal sub-positioning matching portion 133 are correspondingly arranged; the first transverse sub-positioning portion 132 and the first transverse sub-positioning matching portion 23 cooperate with each other, which can limit the first hinge 20 from moving relative to the reinforcing plate 10 along the length direction of the reinforcing plate 10, and the first longitudinal sub-positioning portion 133 and the first longitudinal sub-positioning matching portion 24 cooperate with each other, which can limit the first hinge 20 from moving relative to the reinforcing plate 10 along the width direction of the reinforcing plate 10. Symmetrically, there are multiple second sub-positioning portions 135, and the multiple second sub-positioning portions 135 include a second transverse sub-positioning portion 136 and a second longitudinal sub-positioning portion 137. The second transverse sub-positioning portion 136 is arranged on one or more second positioning structures 121, and the second longitudinal sub-positioning portion 137 is arranged on one or more second positioning structures 121; the second hinge 30 is provided with a plurality of second sub-positioning matching portions 32, and the plurality of second sub-positioning matching portions 32 include a second transverse sub-positioning matching portion 33 and a second longitudinal sub-positioning matching portion 34. The second transverse sub-positioning matching portion 33 is arranged corresponding to the second transverse sub-positioning portion 136, and the second longitudinal sub-positioning matching portion 34 is arranged corresponding to the second longitudinal sub-positioning portion 137; the second transverse sub-positioning portion 136 and the second transverse sub-positioning matching portion 33 cooperate to limit the second hinge 30 from translating relative to the reinforcing plate 10 along the length direction of the reinforcing plate 10, and the second longitudinal sub-positioning portion 137 and the second longitudinal sub-positioning matching portion 34 cooperate to limit the second hinge 30 from translating relative to the reinforcing plate 10 along the width direction of the reinforcing plate 10. In this way, the two degrees of freedom of translation of the first hinge 20 and the second hinge 30 along the length direction and the width direction of the reinforcing plate 10 can be effectively restricted.

[0058] Optionally, combined Figure 4-8As shown, the multiple first sub-positioning parts 131 also include a first rotating sub-positioning part 134, and the first rotating sub-positioning part 134 is arranged in one or more first positioning structures 111; the multiple first sub-positioning matching parts 22 also include a matching first rotating sub-positioning matching part 25, and the first rotating sub-positioning matching part 25 is arranged in one or more first positioning matching structures 21; the first rotating sub-positioning part 134 and the first rotating sub-positioning matching part 25 cooperate with each other to limit the first hinge 20 from rotating relative to the reinforcing plate 10 in a direction perpendicular to the reinforcing plate 10; the multiple second sub-positioning parts 135 also include a second rotating sub-positioning part 138, and the second rotating sub-positioning part 138 is arranged in one or more second positioning structures 121; the multiple second sub-positioning matching parts 32 also include a matching second rotating sub-positioning matching part 35, and the second rotating sub-positioning matching part 35 is arranged in one or more second positioning matching structures 31; the second rotating sub-positioning part 138 and the second rotating sub-positioning matching part 35 cooperate with each other to limit the second hinge 30 from rotating relative to the reinforcing plate 10 in a direction perpendicular to the reinforcing plate 10. In this way, the degree of freedom of the first hinge 20 and the second hinge 30 to rotate in a direction perpendicular to the reinforcing plate 10 can be effectively restricted.

[0059] Taking the first sub-positioning portion 131 as an example, the first transverse sub-positioning portion 132 may be provided on only one first positioning structure 111, or may be provided on multiple first positioning structures 111. The first longitudinal sub-positioning portion 133 may be provided on only one first positioning structure 111, or may be provided on multiple first positioning structures 111. The first rotating sub-positioning portion 134 may be provided on only one first positioning structure 111, or may be provided on multiple first positioning structures 111. It is understood that the first transverse sub-positioning portion 132, the first longitudinal sub-positioning portion 133 and the first positioning structure 111 may also be provided on the same first positioning structure 111.

[0060] Optionally, combined Figure 1-2 and Figure 7 As shown, one of the first positioning structure 111 and the first positioning matching structure 21 is a first rectangular flange 14, and the other is a first rectangular hole 26, and the first rectangular flange 14 abuts against at least two opposite hole walls of the first rectangular hole 26. In this way, the first hinge 20 can be at least limited to move in the relative direction of the two opposite hole walls. When there are multiple first rectangular flanges 14, the length directions of at least two of the multiple first rectangular flanges 14 are perpendicular. In this way, the first rectangular flange 14 can be limited to move in the vertical direction relative to the first rectangular hole 26, thereby limiting the first hinge 20 from moving in any direction in the plane where the vertical direction is located.

[0061] Optionally, combined Figure 2 and Figure 7 As shown, the first positioning structure 111 is a first rectangular flange 14 , and the first positioning matching structure 21 is a first rectangular hole 26 .

[0062] Optionally, the first positioning portion 11 may also be a first rectangular hole, and the first positioning matching portion 21 may also be a first rectangular flange.

[0063] Understandable, combined Figure 2 As shown, when the first rectangular flange 14 also abuts against other hole walls of the first rectangular hole 26 , the moving space of the first rectangular flange 14 relative to the first rectangular hole 26 can be more comprehensively limited, thereby better limiting the position of the first hinge 20 on the surface of the reinforcing plate 10 .

[0064] Optionally, combined Figure 2 As shown, the first rectangular flange 14 extends along the length direction of the reinforcing plate 10, and the first rectangular hole 26 includes two hole walls arranged opposite to each other along the length direction of the reinforcing plate 10. The first rectangular flange 14 abuts against at least two opposite hole walls of the first rectangular hole 26 along the length direction of the reinforcing plate 10. In this way, at least the translation of the first rectangular flange 14 relative to the first rectangular hole 26 along the length direction of the reinforcing plate 10 can be restricted, thereby restricting the translation of the first hinge 20 along the length direction of the reinforcing plate 10.

[0065] Optionally, combined Figure 2 As shown, the first rectangular flange 14 extends along the width direction of the reinforcing plate 10, and the first rectangular hole 26 includes two hole walls arranged opposite to each other along the width direction of the reinforcing plate 10. The first rectangular flange 14 abuts against at least two opposite hole walls of the first rectangular hole 26 along the width direction of the reinforcing plate 10. In this way, at least the translation of the first rectangular flange 14 relative to the first rectangular hole 26 along the width direction of the reinforcing plate 10 can be restricted, thereby restricting the translation of the first hinge 20 along the width direction of the reinforcing plate 10.

[0066] At the same time, since the first rectangular flange 14 and the first rectangular hole 26 abut against each other to form a rectangular contact surface, the first rectangular flange 14 can be restricted from rotating in a direction perpendicular to the reinforcing plate 10, thereby restricting the first hinge 20 from rotating relative to the reinforcing plate 10 in a direction perpendicular to the reinforcing plate 10. At this time, the rectangular contact surface is the first rotating sub-positioning portion 134.

[0067] Optionally, combined Figure 1 , Figure 3 and Figure 8As shown, one of the second positioning structure 121 and the second positioning matching structure 31 is a second rectangular flange 15, and the other is a second rectangular hole 36, and the second rectangular flange 15 abuts against at least two opposite hole walls of the second rectangular hole 36. In this way, the second rectangular flange 15 can at least be restricted from translating relative to the second rectangular hole 36 along the relative directions of the two opposite hole walls. When there are multiple second rectangular flanges 15, the length directions of at least two of the multiple second rectangular flanges 15 are perpendicular. In this way, the second rectangular flange 15 can be restricted from translating relative to the second rectangular hole 36 in the vertical direction, thereby restricting the second hinge 30 from moving in any direction in the plane where the vertical direction is located.

[0068] Optionally, combined Figure 3 and Figure 8 As shown, the second positioning structure 121 is a second rectangular flange 15 , and the second positioning matching structure 31 is a second rectangular hole 36 .

[0069] Optionally, the second positioning portion 12 may also be a second rectangular hole 36 , and the second positioning matching portion may also be a second rectangular flange 15 .

[0070] Understandable, combined Figure 3 As shown, when the second rectangular flange 15 also abuts against other hole walls of the second rectangular hole 36 , the movement space of the second rectangular flange 15 relative to the second rectangular hole 36 can be more comprehensively limited, thereby better limiting the position of the second hinge 30 on the surface of the reinforcing plate 10 .

[0071] Optionally, combined Figure 3 As shown, the second rectangular flange 15 extends along the length direction of the reinforcing plate 10, and the second rectangular hole 36 includes two hole walls arranged opposite to each other along the length direction of the reinforcing plate 10. The second rectangular flange 15 abuts against at least two opposite hole walls of the second rectangular hole 36 along the length direction of the reinforcing plate 10. In this way, at least the translation of the second rectangular flange 15 relative to the second rectangular hole 36 along the length direction of the reinforcing plate 10 can be restricted, thereby restricting the translation of the second hinge 30 along the length direction of the reinforcing plate 10.

[0072] Optionally, combined Figure 3 As shown, the second rectangular flange 15 extends along the width direction of the reinforcing plate 10, and the second rectangular hole 36 includes two hole walls arranged opposite to each other along the width direction of the reinforcing plate 10. The second rectangular flange 15 abuts against at least two opposite hole walls of the second rectangular hole 36 along the width direction of the reinforcing plate 10. In this way, at least the translation of the first rectangular flange 14 along the width direction of the reinforcing plate 10 can be restricted, thereby restricting the translation of the second hinge 30 along the width direction of the reinforcing plate 10.

[0073] At the same time, since the second rectangular flange 15 and the second rectangular hole 36 abut against each other to form a rectangular contact surface, the second rectangular flange 15 can be restricted from rotating in a direction perpendicular to the reinforcing plate 10, thereby restricting the second hinge 30 from rotating relative to the reinforcing plate 10 in a direction perpendicular to the reinforcing plate 10. At this time, the rectangular contact surface is the second rotating sub-positioning portion 138.

[0074] The first positioning structure 111 and the first positioning matching structure 21 or the second positioning structure 121 and the second positioning matching structure 31 may also be positioning structures in which a block and a slot match.

[0075] Optionally, the plurality of first positioning structures 111 are arranged at intervals, and the plurality of second positioning structures 121 are arranged at intervals. In actual operation, the greater the distance between the plurality of first positioning structures 111 or the plurality of second positioning structures 121, the less the influence of the size factor, and the better the positioning effect.

[0076] Combination Figure 2 As shown, the number of the first rectangular flanges 14 is three as an example. The first rectangular flanges 14 include two first rectangular flanges 14 extending along the width direction of the reinforcing plate 10 and one first rectangular flange 14 extending along the length direction of the reinforcing plate 10. The length directions of one of the first rectangular flanges 14 extending along the width direction of the reinforcing plate 10 and one of the first rectangular flanges 14 extending along the length direction of the reinforcing plate 10 are perpendicular, which can limit the translation of the first rectangular flange 14 relative to the first rectangular hole 26. The positioning using three sets of positioning structures can effectively limit the degree of freedom of the first hinge 20, and the processing requirements and size requirements for the positioning holes are low, and the positioning is accurate. In this way, during actual manufacturing, when the size of one of the first positioning structures 111 and the first positioning matching structure 21 is different, the influence of the size factor can be effectively avoided, and the degree of freedom of the first hinge 20 can be better limited. At the same time, the three first rectangular flanges 14 are arranged at intervals, which can enhance the positioning effect. It can be understood that the second rectangular flange 15 is arranged in the above manner, which can also effectively limit the degree of freedom of the second hinge 30. More sets of positioning structures can also be used for positioning.

[0077] It can be understood that the first positioning structure 111 and the first positioning matching structure 21, or the second positioning structure 121 and the second positioning matching structure 31 involved in the embodiment of the present disclosure can be flange structures and through-hole structures of different shapes.

[0078] Optionally, the first rectangular flange 14 and the second rectangular flange 15 are formed by one-time stamping and flanging.

[0079] By using a stamping and flanging process, the first rectangular flange 14 and the second rectangular flange 15 are stamped and flanged at one time on the integrated reinforcing plate 10, so that the relative position of the first rectangular flange 14 and the second rectangular flange is accurate and the stability of the positioning dimension is improved. The first rectangular hole 26 or the second rectangular hole 36 is correspondingly made in the first hinge 20 or the second hinge 30 by a punching process. In this way, riveting is not required and punching and stamping are used to complete the process, which can reduce production costs.

[0080] Optionally, combined Figure 4-8 As shown, the reinforcing plate 10 is further provided with a first fixing portion 16 and a second fixing portion 17; the first hinge 20 is provided with a first fixing matching portion 27, and the first fixing portion 16 matches with the first fixing matching portion 27, so that the first hinge 20 is fixed to one end of the reinforcing plate 10; the second hinge 30 is provided with a second fixing matching portion 37, and the second fixing portion 17 matches with the second fixing matching portion 37, so that the second hinge 30 is fixed to the other end of the reinforcing plate 10. In this way, the first hinge 20 and the second hinge 30 can be accurately and stably fixed to the reinforcing plate 10.

[0081] Optionally, the first fixing portion 16 and the second fixing portion 17 are screw holes, and the first fixing fitting portion 27 and the second fixing fitting portion 37 are through holes. The screw passes through the through hole and is fixed in the screw hole, which can effectively fix the first hinge 20 and the second hinge 30 to the reinforcing plate 10. It can be understood that the first fixing portion 16 and the second fixing portion 17 can also be nuts, and the first fixing fitting portion 27 and the second fixing fitting portion 37 are fixing holes. The bolt passes through the fixing hole and is fixed in the nut, which can effectively fix the first hinge 20 and the second hinge 30 to the reinforcing plate 10.

[0082] The positioning method provided by the embodiment of the present disclosure will not cause the position of the first hinge 20 or the second hinge 30 to be offset due to the different order in which the installation operator screws. Fixing is performed after precise positioning, which can reduce the number of screws and reduce costs. Currently, three screws are usually used to fix the hinge. The number of screws used in the embodiment of the present disclosure can save at least one, from three to two. If it is a T-shaped four-door refrigerator, because the door body is small in size and relatively light in weight, you can consider fixing one hinge with one screw.

[0083] According to a second aspect of an embodiment of the utility model, an embodiment of the present disclosure provides a refrigerator, comprising a hinge reinforcement assembly for a refrigerator according to any one of the above embodiments.

[0084] The refrigerator provided by the embodiment of the present disclosure includes the hinge reinforcement assembly for a refrigerator described in any one of the above embodiments, and thus has all the beneficial effects of the hinge reinforcement assembly for a refrigerator described in any one of the above embodiments, which will not be repeated here.

[0085] Optionally, the refrigerator comprises an inner container and a door body, the reinforcing plate 10 is arranged on the inner container, and the first hinge 20 and the second hinge 30 are both movably connected to the door body. In this way, the problem of unevenness of the two doors of the refrigerator can be solved.

[0086] Optionally, the reinforcing plate 10 is a reinforcing iron. The provision of the reinforcing iron can enhance the load-bearing capacity of the inner container on the door body.
