Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and more specifically, to a refrigerator-assisted hinge. Background Technology

[0002] Currently, refrigeration equipment such as freezers and refrigerators typically use hinges to connect the lid and the body. The hinge components include a hinge head and a hinge base. The hinge base is mounted on the body, and the hinge head is mounted on the lid. The lid opens or closes relative to the body by rotating the hinge head relative to the hinge base. For example... Figure 7 As shown, when the freezer lid is flipped upwards to open, the lid moves towards the wall as a whole. This causes the hinge head to extend beyond the thickness of the hinge base, requiring sufficient clearance between the back of the freezer and the wall to open the lid. This wastes space and makes the freezer look unsightly when placed alongside other furniture. Furthermore, when the lid is too heavy, users need to exert considerable force to open it, resulting in a poor user experience.

[0003] Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a refrigerator-assist hinge, aiming to solve at least one of the technical problems existing in the prior art. To achieve the above objective, the technical solution adopted is as follows:

[0005] A refrigerator-assisted hinge includes a hinge base and a hinge head;

[0006] The hinge base includes a base plate and a pair of first side walls located on the front side of the base plate. A first connecting shaft is provided between the pair of first side walls near the top. Limiting posts are symmetrically installed on the inner sides of the pair of first side walls. The limiting posts are located in front of the first connecting shaft and are spaced apart from the first connecting shaft.

[0007] The hinge head includes a connecting plate and a pair of second sidewalls on the front side of the connecting plate. The outer edge of each second sidewall is an outwardly convex arc. The pair of second sidewalls are symmetrically provided with sliding grooves. The trajectory shape of the sliding grooves is consistent with the outer edge shape of the second sidewalls. The hinge head is located between a pair of first sidewalls. The first connecting shaft passes through the two sliding grooves in sequence. The outer edge of each second sidewall slides in contact with its corresponding limiting post.

[0008] When the hinge head is rotated about the first connecting shaft, the first connecting shaft can slide along the slide groove because the limiting post limits the second side wall.

[0009] Preferably, the top of the base plate has a notch to facilitate the rotation of the hinge head.

[0010] Preferably, the connecting plate is fixedly connected to the side wall of the freezer lid, and the bottom plate is fixedly installed on the top rear side of the freezer body.

[0011] Preferably, it also includes a lever-assisted structure, which includes a second connecting shaft, a bushing, a third connecting shaft, a connector, a first connecting rod, a support base, a second connecting rod, a fourth connecting shaft, a support rod, a spring, and a spring holder;

[0012] The second connecting shaft is fixedly connected between a pair of second sidewalls, and the second connecting shaft is located below the slide groove;

[0013] The bushing is rotatably fitted onto the second connecting shaft;

[0014] The third connecting shaft is fixedly connected between a pair of first sidewalls, and the third connecting shaft is located below the first connecting shaft;

[0015] The connector has a first through hole in the middle, and the connector is rotatably fitted onto the third connecting shaft through the first through hole. The first end of the connector is hinged to the first end of the first connecting rod, and the second end of the first connecting rod is perpendicularly fixed to the outer wall of the bushing.

[0016] The support base has a second through hole in the middle, the support base is located below the third connecting shaft, and the two ends of the support base are respectively fixedly connected to the corresponding first side wall through the second connecting rod.

[0017] Vertical grooves are symmetrically provided on a pair of first sidewalls;

[0018] The spring holder is located below the support base, and the two ends of the spring holder are symmetrically connected to the fourth connecting shaft. Each fourth connecting shaft passes through the corresponding vertical slide groove and can slide along the vertical slide groove.

[0019] The support rod passes through the second through hole, the top end of the support rod is hinged to the second end of the connector, and the bottom end of the support rod is fixedly and vertically connected to the spring seat.

[0020] The spring is mounted on the support rod, with the top end of the spring fixedly connected to the support base and the bottom end of the spring fixedly connected to the spring holder.

[0021] Preferably, the first through hole is an oblong hole.

[0022] Preferably, the first end of the connector is provided with a first U-shaped groove, the first end of the first connecting rod is vertically fixed with a first rotating shaft, the first end of the first connecting rod is located in the first U-shaped groove, and the first rotating shaft is rotatably connected to the two end faces of the first U-shaped groove.

[0023] Preferably, the second end of the connector is provided with a second U-shaped groove, the top end of the support rod is vertically fixed with a second rotating shaft, the top end of the support rod is located in the second U-shaped groove, and the second rotating shaft is rotatably connected to the two end faces of the second U-shaped groove.

[0024] Preferably, the spring is in a compressed state.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The refrigerator equipped with the present invention has a hinge that allows the hinge head to move backward when the operator flips the refrigerator lid upward, so that the refrigerator lid moves backward as a whole. During the entire process of opening the refrigerator lid, the hinge head will not move forward beyond the thickness of the hinge seat. Compared with the prior art, the hinge seat on the back of the refrigerator can be completely fitted to the wall, which can further reduce the distance between the refrigerator and the wall, improve space utilization and overall aesthetics.

[0027] In addition, when the operator flips the freezer lid upwards, the connector forms a lever structure with the third connecting shaft as the fulcrum. The effort arm of the lever is greater than the resistance arm, driving the hinge head to rotate, thus assisting in opening the freezer lid and improving the user experience. When closing the freezer lid, the operator flips it downwards. At this time, the connector forms a lever structure with the third connecting shaft as the fulcrum. Under the action of the freezer lid's own weight, the lever structure compresses the spring, providing a buffer for closing the freezer lid and simultaneously storing force for the next opening of the freezer lid.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] Furthermore, in the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] like Figure 1 As shown, a preferred embodiment of the present invention provides a refrigerator-assisted hinge, which includes: a hinge base 1, a hinge head 2, and a lever-assisted structure.

[0040] like Figure 3 and Figure 6 As shown, the hinge base 1 includes a base plate 3 and a pair of first sidewalls 4 located on the front side of the base plate 3. Specifically, the left and right sides of the base plate 3 are formed into a pair of first sidewalls 4 by a bending process. The hinge base 1 is assembled to the freezer body 5, that is, the base plate 3 is fixedly installed on the top rear side of the freezer body 5 by bolts.

[0041] A first connecting shaft 6 is provided near the top between a pair of first sidewalls 4, wherein the two ends of the first connecting shaft 6 are respectively vertically and fixedly connected to the corresponding first sidewalls 4. Limiting posts 7 are symmetrically installed on the inner side of the pair of first sidewalls 4. Specifically, the limiting posts 7 are located in front of the first connecting shaft 6, and the limiting posts 7 are spaced apart from the first connecting shaft 6. The limiting posts 7 are vertically and fixedly connected to the first sidewalls 4.

[0042] like Figure 4 and Figure 6 As shown, the hinge head 2 includes a connecting plate 8 and a pair of second sidewalls 9 located on the front side of the connecting plate 8. Specifically, the left and right sides of the connecting plate 8 are formed into a pair of second sidewalls 9 by a bending process. The hinge head 2 is assembled to the freezer lid 10, that is, the connecting plate 8 and the sidewalls of the freezer lid 10 are fixedly connected by bolts.

[0043] Each second sidewall 9 has an outwardly convex arc-shaped outer edge, and symmetrical grooves 11 are provided on a pair of second sidewalls 9. Specifically, the trajectory shape of the grooves 11 is consistent with the shape of the outer edge of the second sidewall 9. The hinge head 2 is located between a pair of first sidewalls 4, and the first connecting shaft 6 passes through the two grooves 11 in sequence. The outer edge of each second sidewall 9 is in sliding contact with its corresponding limiting post 7.

[0044] When the freezer lid 10 is opened, it is immediately... Figures 1 to 2 During the process, the operator flips the freezer lid 10 upwards and drives the hinge head 2 to rotate around the first connecting shaft 6. Since the limiting post 7 limits the second side wall 9, the first connecting shaft 6 can slide along the slide groove 11 while the hinge head 2 rotates. In addition, since the first connecting shaft 6 is stationary, the hinge head 2 will move backwards, that is, the freezer lid 10 moves backwards as a whole. During the entire process of opening the freezer lid 10, the hinge head 2 will not move forward beyond the thickness of the hinge seat 1.

[0045] When the freezer lid is fully opened, as follows: Figure 6 As shown, compared with the prior art, the freezer equipped with the hinge of the present invention can completely fit the hinge seat 1 on the back of the freezer to the wall, which can further reduce the distance between the freezer and the wall, improve space utilization and overall aesthetics.

[0046] When the freezer lid 10 is closed, it is immediately... Figures 2 to 1 The process is the reverse of the above-described process of opening the freezer lid 10, and will not be repeated here.

[0047] Furthermore, a notch 12 is provided at the top of the base plate 3 of the hinge seat 1 to facilitate the rotation of the hinge head 2 and prevent the base plate 3 from restricting the rotation of the hinge head 2.

[0048] like Figure 5 As shown, the lever-assisted structure includes: a second connecting shaft 13, a bushing 14, a third connecting shaft 15, a connector 16, a first connecting rod 17, a support seat 18, a second connecting rod 19, a fourth connecting shaft 20, a support rod 21, a spring 22, and a spring holder 23.

[0049] The second connecting shaft 13 is fixedly connected between a pair of second sidewalls 9. Specifically, the second connecting shaft 13 is located below the slide groove 11, and the two ends of the second connecting shaft 13 are respectively fixedly connected to the corresponding second sidewalls 9 perpendicularly.

[0050] The bushing 14 is rotatably mounted on the second connecting shaft 13.

[0051] The third connecting shaft 15 is fixedly connected between a pair of first sidewalls 4. Specifically, the third connecting shaft 15 is located below the first connecting shaft 6, and the two ends of the third connecting shaft 15 are respectively fixedly connected to the corresponding first sidewalls 4 perpendicularly.

[0052] A first through hole 24 is provided in the middle of the connector 16, through which the connector 16 is rotatably fitted onto the third connecting shaft 15. The first end of the connector 16 is hinged to the first end of the first connecting rod 17. Specifically, the first end of the connector 16 is provided with a first U-shaped groove, and the first end of the first connecting rod 17 is vertically fixed with a first rotating shaft. The first end of the first connecting rod 17 is located in the first U-shaped groove, and the first rotating shaft is rotatably connected to the two end faces of the first U-shaped groove. The second end of the first connecting rod 17 is vertically fixed to the outer wall of the bushing 14.

[0053] Furthermore, the first through hole 24 is an elongated hole, and when the connector 16 rotates about the third connecting shaft 15, the third connecting shaft 15 can slide along the length direction of the first through hole 24.

[0054] The support base 18 has a second through hole 25 in the middle position. The support base is located below the third connecting shaft 15, and both ends of the support base 18 are fixedly connected to the corresponding first side wall 4 through a second connecting rod 19.

[0055] Vertical grooves 26 are symmetrically provided on a pair of first sidewalls 4.

[0056] The spring holder 23 is located below the support base 18. A fourth connecting shaft 20 is symmetrically connected to both ends of the spring holder 23. Each fourth connecting shaft 20 passes through the corresponding vertical slide groove 26 and can slide along the vertical slide groove 26.

[0057] The support rod 21 passes through the second through hole 25 on the support base 18. The top end of the support rod 21 is hinged to the second end of the connector 16. Specifically, the second end of the connector 16 is provided with a second U-shaped groove. The top end of the support rod 21 is vertically fixed with a second rotating shaft, which is located in the second U-shaped groove. The second rotating shaft is rotatably connected to both ends of the second U-shaped groove. The bottom end of the support rod 21 is fixedly and vertically connected to the spring seat 23.

[0058] Spring 22 is mounted on support rod 21. Specifically, spring 22 is in a compressed state, with the top end of spring 22 fixedly connected to support base 18 and the bottom end of spring 22 fixedly connected to spring holder 23.

[0059] When the freezer lid 10 is opened, it is immediately... Figures 1 to 2During the process, the operator flips the freezer lid 10 upwards. Spring 22, under its own elastic force, drives spring holder 23 downwards, simultaneously driving support rod 21 downwards. At this time, connector 16 forms a lever structure with the third connecting shaft 15 as the fulcrum, and the effort arm of the lever is greater than the resistance arm. The elastic force of spring 22 is amplified by the effort-saving lever and then transmitted to hinge head 2 via first connecting rod 17, driving hinge head 2 to rotate, thus assisting in opening the freezer lid 10 and improving the user experience. When the freezer lid 10 is fully opened, spring 22 is in a slightly compressed state.

[0060] When the freezer lid 10 is closed, it is immediately... Figures 2 to 1 During the process, the operator flips the freezer lid 10 downwards and simultaneously drives the hinge head 2 to rotate. At this time, the connector 16 forms a lever structure with the third connecting shaft 15 as the fulcrum. Under the action of the freezer lid 10's own weight, the lever structure can drive the support rod 21 to move upwards and compress the spring 22, which plays a buffering role in closing the freezer lid and at the same time stores force for the next opening of the freezer lid 10.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
