Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a hinge and a refrigeration device having the same. Background Technology

[0002] Refrigeration equipment such as refrigerators, freezers, and wine cabinets typically use hinges to connect the door and the cabinet to open or close the door. However, once the door is opened to a certain angle, it needs to be stopped so that users can access items.

[0003] When hinges are installed on refrigeration equipment, the entire hinge protrudes outside the casing. In the prior art, hinges usually have a large thickness in the direction perpendicular to the hinge mounting surface of the refrigeration equipment. The large thickness of the hinge will increase the size of the refrigeration equipment, thereby increasing the space occupied during packaging and use, resulting in a smaller packing volume during storage and transportation, and thus increasing transportation and storage costs. Summary of the Invention

[0004] To address the aforementioned technical problems, the purpose of this utility model is to provide a hinge and a refrigeration device having the same, thereby solving the problems of existing hinges having large thickness and occupying a large amount of space during storage, transportation, and use.

[0012] As a further improvement of one embodiment of the present utility model, the limiting plates are provided in pairs at intervals, and each pair of the limiting plates is provided with the limiting groove. The sliding mechanism includes a sliding shaft, and the two ends of the sliding shaft are respectively connected to the pair of the limiting grooves.

[0013] As a further improvement of one embodiment of the present invention, each of the limiting plates has a gap between it and the adjacent sidewall.

[0015] As a further improvement of one embodiment of the present invention, the end face of the side wall away from the bottom wall is located on the side of the limiting mechanism away from the bottom wall.

[0016] As a further improvement of one embodiment of the present utility model, the hinge further includes a stop mechanism, the stop mechanism including a first stop portion disposed on the housing connecting seat and a second stop portion disposed on the door connecting seat; the housing connecting seat further includes a rotating shaft, the door connecting seat being rotatably connected to the rotating shaft; the door connecting seat includes a swing shaft parallel to the rotating shaft, the sliding mechanism includes a sliding shaft, the connecting member being pivotally connected to both the sliding shaft and the swing shaft; when the sliding mechanism is located at one end of the limiting groove away from the door connecting seat, the axis of the swing shaft is located on the side of the plane formed by the axis of the rotating shaft and the axis of the sliding shaft away from the bottom wall, the first stop portion abuts against the second stop portion to restrict the door connecting seat from rotating about the housing connecting seat toward the side of the bottom wall away from the limiting mechanism.

[0017] As a further improvement of one embodiment of the present invention, the limiting mechanism is connected to at least one of the pair of sidewalls.

[0018] As a further improvement of an embodiment of the present utility model, the elastic support includes an elastic element and a support rod connected to the sliding mechanism. The elastic element is sleeved on the outer periphery of the support rod. The end of the elastic element away from the sliding mechanism abuts against the box connecting seat. During the rotation of the door connecting seat around the box connecting seat, the elastic element always has a compressive deformation and provides support force to the support rod.

[0019] As a further improvement of an embodiment of the present utility model, the box connecting seat further includes a support seat transversely disposed between the pair of side walls. The support seat is disposed at the end of the box connecting seat away from the door connecting seat. The support seat is provided with an opening for the support rod to pass through.

[0021] Compared with the prior art, the present invention has the following beneficial effects: The hinge of the present invention and the refrigeration equipment having it can not only reduce the thickness of the hinge in the direction perpendicular to the hinge mounting surface of the refrigeration equipment, thus reducing the space occupied by the hinge in the box and reducing transportation and storage costs, but also ensure that the sliding mechanism always moves in a straight line during the opening or closing of the door relative to the box, avoiding movement of the sliding mechanism in the direction perpendicular to the hinge mounting surface of the box, thereby reducing the space occupied by the hinge during use and improving space utilization; in addition, the limiting plate is set between a pair of side walls, which also avoids the loss of strength of the side walls. Under the premise of meeting the hinge strength, the thickness of the side walls in the direction perpendicular to the hinge mounting surface of the refrigeration equipment can be minimized.

[0027] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0028] One embodiment of this utility model provides a hinge 100 and a refrigeration device having the hinge 100. The hinge 100 not only makes it easier for users to open the door, but also greatly reduces the thickness of the hinge 100 in the direction perpendicular to the hinge mounting surface of the refrigeration device, thereby reducing the overall size of the refrigeration device.

[0029] like Figures 1 to 3 As shown, a refrigeration device provided in one embodiment of the present invention includes a cabinet, a door, and a hinge 100. A refrigeration space is provided inside the cabinet. The door is assembled to the cabinet via the hinge 100 and can rotate relative to the cabinet to open or close the refrigeration space. The refrigeration device can be specifically configured as a refrigerator, freezer, wine cabinet, etc.

[0030] The hinge 100 in this embodiment includes a housing connecting seat 1 and a door connecting seat 2 rotatably connected thereto. The door connecting seat 2 is fixedly connected to the door, and the housing connecting seat 1 is fixedly connected to the housing.

[0031] To clearly illustrate the connection position relationship, in this embodiment, the direction of the hinge 100 toward the box is defined as front, and the opposite direction is defined as back; the direction of the door relative to the box is defined as up, and the opposite direction is defined as down; and the directions from the front directly opposite to both sides of the hinge 100 are defined as left and right, respectively.

[0032] The door connecting seat 2 has an open position for opening the door and a closed position for closing the door. In this embodiment, the door is in the closed position when it is located on the plane defined by the front-back direction and the left-right direction. From the closed position, the door flips upwards and backwards around the housing to open the cooling space; from the open position, the door flips downwards and forwards around the housing to close the cooling space. Here, the hinge mounting surface is the rear surface of both the housing and the door.

[0033] Combination Figure 2 The hinge 100 also includes a sliding mechanism 3, a connector 4, an elastic support 5, and a limiting mechanism 6. The connector 4 pivotally connects the door body connecting seat 2 and the sliding mechanism 3; one end of the elastic support 5 is connected to the sliding mechanism 3, and the other end abuts against the box body connecting seat 1; the limiting mechanism 6 includes a limiting plate 61 and a limiting groove 62 provided in the limiting plate 61.

[0034] The sliding mechanism 3 is slidably engaged in the limiting groove 62 and can drive the elastic support 5 to move linearly along the limiting groove 62. Moreover, the end of the limiting groove 62 can be within the range of motion of the sliding mechanism 3, thereby limiting the range of rotation of the door connecting seat 2 relative to the box connecting seat 1, and thus limiting the range of opening angle of the door relative to the box. When the sliding mechanism 3 moves to one end of the limiting groove 62 near the door connecting seat 2, the door opens to the maximum opening angle and is suspended under the limitation of the limiting groove 62.

[0035] In this embodiment, the sliding mechanism 3 moves up and down along the limiting groove 62, thereby reducing the space occupied by the hinge 100 in the direction perpendicular to the hinge mounting surface of the refrigeration equipment, i.e., the front-to-back direction, during use. In other embodiments, the sliding mechanism 3 can also move along the limiting groove 62 in other directions within the plane defined by the up-down and left-to-right directions, which can also reduce the space occupied by the hinge 100 in the direction perpendicular to the hinge mounting surface of the refrigeration equipment, i.e., the front-to-back direction, during use.

[0036] See Figures 1 to 3 The housing connecting seat 1 includes a pair of side walls 11 that are spaced apart and opposite to each other. In this embodiment, the pair of side walls 11 are spaced apart and opposite to each other. The limiting plate 61 is provided on the housing connecting seat 1 and is located between the pair of side walls 11.

[0037] Through the above design, not only can the thickness of the hinge 100 in the direction perpendicular to the hinge mounting surface of the refrigeration equipment be reduced, thus reducing its space occupation during packaging and lowering transportation and storage costs, but also the sliding mechanism 3 always moves in a straight line during the opening or closing of the door relative to the box, avoiding movement of the sliding mechanism 3 in the direction perpendicular to the hinge mounting surface of the box. This further reduces the space occupied by the hinge 100 during use and improves space utilization. In addition, the limiting plate 61 is set between a pair of side walls 11, which also avoids the loss of strength of the side walls 11. Under the premise of meeting the strength requirements of the hinge 100, the thickness of the side walls 11 in the direction perpendicular to the hinge mounting surface of the refrigeration equipment can be minimized.

[0038] The housing connecting seat 1 also includes a rotating shaft 12, and the door connecting seat 2 is rotatably connected to the rotating shaft 12. The limiting groove 62 extends linearly along the axis perpendicular to the rotating shaft 12. In this embodiment, the rotating shaft 12 extends left and right, and the limiting groove 62 extends up and down.

[0039] The door connecting seat 2 includes a base plate 21, a pair of oppositely arranged side plates 22, and a swing shaft 23 parallel to the rotating shaft 12. The pair of side plates 22 are respectively connected to the left and right ends of the base plate 21 and are located on the same side of the base plate 21. The pair of side plates 22 are located between a pair of side walls 11 and correspond one-to-one with the pair of side walls 11. The swing shaft 23 connects to the pair of side plates 22. The connecting piece 4 is pivotally connected to the sliding shaft 31 and the swing shaft 23. The swing shaft 23 is located between a pair of side walls 11, that is, the swing shaft 23 is not connected to the box connecting seat 1. The arc groove provided on the side wall 11 of the box connecting seat 1 in the prior art is eliminated, avoiding the limitation of the size and bearing strength of the arc groove on the hinge 100. The thickness of the hinge 100 can be reduced, increasing the packing capacity during storage and transportation and reducing the space occupied during use.

[0040] The housing connecting seat 1, door connecting seat 2, connecting piece 4, and sliding mechanism 3 together constitute a crank-slider mechanism, which converts the pivotal motion of the door connecting seat 2 into the linear motion of the sliding mechanism 3. During the process of the door rotating and opening relative to the housing, the door connecting seat 2, which is fixedly connected to the door, rotates around the housing connecting seat 1. The door connecting seat 2 pulls the connecting piece 4, causing the sliding mechanism 3 to move together. The sliding mechanism 3 performs linear motion under the constraint of the limiting mechanism 6.

[0041] Preferably, a pair of limiting plates 61 are spaced apart, and each pair of limiting plates 61 is provided with the limiting groove 62. The sliding mechanism 3 includes a sliding shaft 31, and the two ends of the sliding shaft 31 are respectively matched in the pair of limiting grooves 62. Thus, the sliding shaft 31 can move linearly along the limiting groove 62, which can not only reduce the thickness of the hinge 100 in the direction perpendicular to the hinge mounting surface of the box, but also improve the assembly strength of the sliding shaft 31 and the limiting plate 61, thereby improving the stability of the movement of the sliding mechanism 3.

[0042] Specifically, the distance between a pair of limiting plates 61 is less than the axial length of the sliding shaft 31, thereby ensuring the stability of the connection between the sliding shaft 31 and the pair of limiting grooves 62.

[0043] Preferably, a pair of limiting plates 61 are arranged in parallel, and correspondingly, a pair of limiting grooves 62 are also arranged in parallel. The sliding mechanism 3 also includes a pair of anti-detachment parts 32 disposed at both ends of the sliding shaft 31. The pair of anti-detachment parts 32 are respectively located on the side of the pair of limiting plates 61 away from each other, so as to prevent the sliding shaft 31 from moving left and right during the movement and improve the movement stability of the sliding shaft 31.

[0044] Furthermore, there is a gap between each of the limiting plates 61 and the adjacent side wall 11. This prevents mechanical interference between the sliding shaft 31 and the side wall 11 during the rotation of the door connecting seat 2 around the box connecting seat 1.

[0045] The housing connecting seat 1 also includes a bottom wall 13 that connects the pair of side walls 11, and the housing connecting seat 1 is fixedly connected to the housing through the bottom wall 13.

[0046] In this embodiment, the limiting mechanism 6 is connected to the bottom wall 13, and the limiting mechanism 6 and the pair of side walls 11 are located on the same side of the bottom wall 13. That is, the pair of side walls 11 and the limiting mechanism 6 are both located on the side of the bottom wall 13 away from the housing. The bottom wall 13 and the pair of side walls 11 together enclose the movement space of the sliding mechanism 3.

[0047] Specifically, a pair of limiting plates 61 are connected to the bottom wall 13 respectively, which can not only improve the strength of the limiting mechanism 6, but also avoid reducing the strength of the box connecting seat 1.

[0048] Preferably, the end face of the side wall 11 away from the bottom wall 13 is located on the side of the limiting mechanism 6 away from the bottom wall 13. Specifically, in this embodiment, the end face of the side wall 11 away from the bottom wall 13 is located on the side of the limiting plate 61 away from the bottom wall 13. That is, the height of the limiting plate 61 in the direction perpendicular to the bottom wall 13 is less than the height of the side wall 11 in the direction perpendicular to the bottom wall 13, thereby avoiding an increase in the thickness of the hinge 100 in the direction perpendicular to the mounting surface of the hinge 100 of the housing.

[0049] In a variation of the implementation, the limiting mechanism 6 may also be connected to at least one of a pair of sidewalls 11.

[0050] Specifically, the limiting mechanism 6 may be connected to only one of the side walls 11. The specific connection method may be configured such that the limiting mechanism 6 is connected to one of the side walls 11 through a connecting part; or, the limiting mechanism 6 may be connected to both of the side walls 11. For example, the pair of limiting plates 61 of the limiting mechanism 6 may be connected to the pair of side walls 11 respectively.

[0051] Combination Figure 4 Furthermore, the elastic support 5 includes an elastic element 51 and a support rod 52 connected to the sliding mechanism 3. Specifically, the support rod 52 is connected to the sliding shaft 31, and the elastic element 51 is sleeved on the outer periphery of the support rod 52. The end of the elastic element 51 away from the sliding mechanism 3 abuts against the box connecting seat 1. During the rotation of the door connecting seat 2 around the box connecting seat 1, the elastic element 51 always has a compressive deformation and provides support force to the support rod 52. In this way, the elastic restoring force of the elastic element 51 provides support force to the support rod 52, thereby making it easier to open the door.

[0052] Furthermore, the housing connecting seat 1 also includes a support seat 14 horizontally disposed between a pair of side walls 11. The support seat 14 is located at the end of the housing connecting seat 1 away from the door connecting seat 2, and the support seat 14 is provided with an opening for the support rod 52 to pass through.

[0053] In this embodiment, the support rod 52 extends toward the support base 14 and passes through the opening. During the process of the door opening or closing relative to the box, the support rod 52 can move up and down relative to the support base 14, and the support rod 52 is always placed in the opening without coming out of the opening.

[0054] Furthermore, a limiting protrusion 521 is provided at one end of the support rod 52 near the sliding mechanism 3. The two ends of the elastic member 51 abut against the support seat 14 and the limiting protrusion 521 respectively, so as to support the support rod 52 to move linearly along the limiting groove 62 synchronously with the sliding mechanism 3, thereby avoiding the increase in the space occupied by the hinge 100 due to the movement of the sliding mechanism 3 in the direction perpendicular to the hinge mounting surface of the box.

[0055] Under the combined action of the sliding mechanism 3 and the elastic element 51, the support rod 52 can move relative to the support seat 14 along the extension direction of the limiting groove 62. That is, the movement mode of the sliding shaft 31 and the elastic support element 5 is limited to vertical linear movement, which greatly reduces the activity space required inside the hinge 100. This avoids the problem of traditional hinge 100 occupying a lot of space due to the back-and-forth swing of the elastic support element 5. Thus, the hinge 100 can be made very thin without affecting the strength of the hinge 100 structure.

[0056] Preferably, the elastic element 51 is a spring. During the rotation of the door connecting seat 2 around the box connecting seat 1, the spring is always in a compressed state. In this way, when the door connecting seat 2 rotates around the box connecting seat 1 during the opening process, the compressed spring gradually recovers its deformation, providing support for the opening of the door and playing an auxiliary role in opening the door, making it easier to open the door.

[0057] In this embodiment, when the door connecting seat 2 is in the closed position, that is, when the sliding mechanism 3 is located at the end of the limiting groove 62 away from the door connecting seat 2, the axis of the swing shaft 23 is located on the side of the plane formed by the axis of the rotating shaft 12 and the axis of the sliding shaft 31 away from the bottom wall 13. In this way, during the transportation process, under the action of the elastic restoring force of the elastic element 51, the door connecting seat 2 tends to rotate around the box connecting seat 1 toward the side of the bottom wall 13 away from the limiting mechanism 6, so that when the door is closed, the door can press against the box to prevent the refrigeration equipment from leaking cold.

[0058] Combination Figure 5 Furthermore, the hinge 100 also includes a stop mechanism, which includes a first stop portion 71 disposed on the housing connecting seat 1 and a second stop portion 72 disposed on the door connecting seat 2. When the sliding mechanism 3 is located at the end of the limiting groove 62 away from the door connecting seat 2, that is, when the door connecting seat 2 is in the closed position, the first stop portion 71 abuts against the second stop portion 72 to restrict the door connecting seat 2 from rotating around the housing connecting seat 1 toward the bottom wall 13 away from the limiting mechanism 6. This can prevent the door connecting seat 2 from reciprocating around the housing connecting seat 1 during transportation, which would cause wear or even damage and thus affect its service life.

[0059] Furthermore, the first stop 71 is provided at one end of the housing connecting seat 1 away from the support seat 14, specifically on the side wall 11; the second stop 72 is provided on the side plate 22 of the door connecting seat 2 and extends from the side plate 22 toward the adjacent side wall 11.

[0060] Preferably, the first stop 71 and the second stop 72 are provided in a pair corresponding to each other. The pair of first stop 71 are respectively provided on a pair of side walls 11, and the pair of second stop 72 are respectively provided on a pair of side plates 22 and extend away from each other, thereby improving the stability of the cooperation between the first stop 71 and the second stop 72.

[0061] Compared with the prior art, this embodiment has the following beneficial effects: The hinge 100 of this utility model and the refrigeration equipment having it can not only reduce the thickness of the hinge 100 in the direction perpendicular to the hinge mounting surface of the refrigeration equipment, reduce the space occupied by it in the box, and reduce transportation and storage costs, but also ensure that the sliding mechanism 3 always moves in a straight line during the opening or closing of the door relative to the box, avoiding the sliding mechanism 3 from moving in the direction perpendicular to the hinge mounting surface of the box, thereby reducing the space occupied by the hinge 100 during use and improving space utilization; in addition, the limiting plate 61 is set between a pair of side walls 11, which also avoids the strength loss of the side walls 11. Under the premise of satisfying the strength of the hinge 100, the thickness of the side walls 11 in the direction perpendicular to the hinge mounting surface of the refrigeration equipment can be minimized.

[0062] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementation methods or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
