Abstract

The present invention discloses a hinge and a refrigeration device, including a cabinet hinge seat and a door hinge seat rotatably connected thereto, and also including a sliding part slidably connected to the cabinet hinge seat, a connecting member pivotally connected to the sliding part and the door hinge seat, a limiting part for limiting the linear motion of the sliding part, and a plurality of elastic supporting members, one end of each elastic supporting member is connected to the sliding part, and the other end abuts against the cabinet hinge seat. The sliding part prevents the elastic supporting member from swinging back and forth, and eliminates the arc groove provided on the cabinet hinge seat in the traditional hinge, thereby preventing the hinge from being limited by the size and pressure bearing strength of the arc groove. The plurality of elastic supporting members can reduce the strength requirements for each elastic supporting member, making the outer diameter of each elastic supporting member small, so that the hinge can be made very thin without affecting the strength of the hinge structure, increasing the packing volume during storage and transportation, and reducing the occupied space during use.

Description

Technical Field

[0001] The invention relates to a hinge, and in particular to a hinge and a refrigeration device having the hinge. Background Art

[0002] Refrigeration equipment such as refrigerators, freezers, wine cabinets, etc. usually use hinges to connect the door body and the cabinet body to open or close the door body, but after the door body is opened to a certain angle, the door body needs to be suspended so that users can store and retrieve items. The hinges of existing refrigeration equipment usually have an arc groove on the side wall of the cabinet hinge seat. During the process of flipping and opening the door body, the swing shaft of the door hinge seat reciprocates in the arc groove to open or close the door body, and the door body is suspended after opening through the end of the arc groove.

[0003] However, the arc groove itself needs to occupy a certain side wall thickness, and further, a certain thickness margin needs to be reserved between the two ends of the arc groove and the boundary of the side wall in the thickness direction of the side wall to ensure the strength of the side wall. Moreover, since the door body of the refrigeration equipment generally has a large gravity, it is necessary to ensure that the reserved thickness margin is large enough to bear the weight of the door body, resulting in the thickness of the hinge cannot be made thinner; in addition, the elastic support part used to support the door body in the hinge will swing back and forth with the axis in the arc groove during the up and down movement, and also needs to occupy the space of the hinge in the thickness direction, further limiting the thickness of the hinge from being made thinner; further, the hinge is generally protruding from the outside of the refrigeration equipment, which makes the overall thickness of the refrigeration equipment larger, the packaging volume is reduced during storage and transportation, and a large amount of space is occupied when in use.

[0033] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0034] An embodiment of the present invention provides a hinge and a refrigeration device having the hinge, wherein the structure of the hinge is redesigned so that the hinge is made thinner while maintaining normal working state, thereby reducing the size of the refrigeration device.

[0035] like Figure 1 or Figure 2 As shown, a refrigeration device provided in an embodiment of the present application includes a hinge 1, a cabinet 2 and a door 3. The cabinet 2 encloses a refrigeration space. The door 3 is assembled on the cabinet 2 and can rotate relative to the cabinet 2 to open or close the refrigeration space. The refrigeration device can be specifically configured as a refrigerator, a freezer, a wine cabinet, etc. The door 3 is connected to the cabinet 2 by a hinge 1. The hinge 1 supports the opening and closing of the door 3. The thin thickness of the hinge 1 can increase the packing volume during the transportation of the refrigeration device.

[0036] like Figure 3~Figure 7 As shown, the hinge 1 of this embodiment includes a cabinet hinge seat 11 and a door hinge seat 12 rotatably connected thereto, the door hinge seat 12 is fixedly connected to the door body 3, and the cabinet hinge seat 11 is fixedly connected to the cabinet body 2. The door body 3 of this embodiment is opened from the side of the cabinet body 2, and correspondingly, the hinge 1 is arranged on the side of the cabinet body 2 and the door body 3. In order to clearly illustrate the connection position relationship, in this embodiment, the direction of the hinge 1 toward the cabinet body 2 is defined as the front, and the opposite direction is defined as the rear, the direction of the door body 3 relative to the cabinet body 2 is defined as the top, and the opposite direction is defined as the bottom, and the two sides facing the hinge 1 from the front are defined as the left and the right respectively.

[0037] The hinge 1 in this embodiment also includes a sliding part slidably connected to the cabinet hinge seat 11, a connecting member 13 rotatably connected to the door hinge seat 12 and the sliding part, and a limiting part for limiting the linear motion of the sliding part. Figure 3 or Figure 4As shown, the limiting part can be set on the cabinet hinge seat 11, or on the packaging cover plate of the hinge 1, or at multiple places at the same time, and its function is to limit the movement of the sliding part so that it can only make linear motion under the traction of the connecting member 13. The cabinet hinge seat 11, the door hinge seat 12, the connecting member 13, the sliding part and the limiting part together constitute a crank slider mechanism, which converts the rotational motion of the door hinge seat 12 into the linear motion of the sliding part. In the process of the door body 3 flipping and opening around the hinge 1, the door hinge seat 12 fixed on the door body 3 is driven to rotate around the cabinet hinge seat 11, and the door hinge seat 12 pulls the connecting member 13 to drive the sliding part to move together, and the sliding part makes linear motion under the restriction of the limiting part.

[0038] The hinge 1 also includes a plurality of elastic support members 16, which are arranged side by side at intervals, one end of each elastic support member 16 is connected to the sliding portion, and the other end abuts against the cabinet hinge seat 11. The sliding portion drives the elastic support member 16 to move in a straight line, which distinguishes the hinge 1 of this embodiment from the swinging movement of the elastic support member in the traditional hinge. On the one hand, the sliding portion greatly reduces the movable space required for the elastic support member 16 inside the hinge 1, avoiding the problem of the elastic support member 16 swinging back and forth and occupying a large amount of space, and eliminates the arc groove provided on the cabinet hinge seat 11 in the traditional hinge, avoiding the hinge 1 being limited by the size and pressure-bearing strength of the arc groove, so that the hinge 1 can be made very thin without affecting the strength of the hinge 1 structure, increasing the packing volume during storage and transportation, and reducing Less space is occupied when in use; on the other hand, a plurality of elastic support members jointly share the supporting function of the door hinge seat 12 and the door body 3, which can reduce the strength requirement of each elastic support member, thereby making the outer diameter of each elastic support member smaller and further reducing the thickness of the hinge 1; in addition, by the movement of the limiting portion in the sliding portion, the sliding portion can be used to limit the opening angle of the door body 3 relative to the cabinet body 2, and when the limiting portion moves to one end of the sliding portion close to the door hinge seat 12, the door body 3 opens to the maximum opening angle and hovers under the restriction of the sliding portion.

[0039] The cabinet hinge seat 11 also includes a support seat 114, and multiple elastic support members 16 are all supported on the support seat 114 and the sliding part. The multiple elastic support members 16 have the same structure. After being evenly spaced, the forces applied to the support seat 114 and the sliding part are of the same magnitude and direction. The sliding part is supported by the multiple elastic support members 16 with forces of the same magnitude and direction. Under the support of the support seat 114, one end of the elastic support member 16 connected to the sliding part moves synchronously with the movement of the sliding part. Since the sliding part moves in a straight line, the multiple elastic support members 16 also move in a straight line, thereby reducing the required activity space inside the hinge 1 and making the thickness of the hinge 1 thinner.

[0040] like Figure 4 or Figure 5 As shown, specifically, in this embodiment, two elastic support members 16 are provided, and the two elastic support members 16 are provided on both sides of the connecting member 13. Preferably, the two elastic support members 16 are symmetrically provided on both sides of the connecting member 13, so that the two elastic support members 16 can evenly share the supporting effect on the door hinge seat 12 and the door body 3, so that the connecting member 13 is evenly stressed. In other embodiments, the number of elastic support members 16 can also be selected and set according to actual needs.

[0041] See also Figures 3 to 5 The cabinet hinge seat 11 includes a cabinet connecting plate 113 and a rotating shaft 111 . The door hinge seat 12 is rotatably connected to the rotating shaft 111 . The rotating shaft 111 is parallel to the cabinet connecting plate 113 .

[0042] Preferably, the sliding part moves in a direction parallel to the cabinet connecting plate 113 and perpendicular to the rotating shaft 111 under the restriction of the limiting part, further pulling the elastic support member 16 to move with the sliding part parallel to the cabinet connecting plate 113, limiting the movement of the elastic support member 16 to a plane parallel to the cabinet connecting plate 113, and the sliding part moves linearly in the up and down directions, and the elastic support member 16 is also compressed or stretched in the up and down directions, thereby avoiding the movement of the sliding part and the elastic support member 16 in a direction perpendicular to the cabinet connecting plate 113, reducing the space occupied by the hinge 1, and allowing the hinge 1 to be made thinner.

[0043] Among them, the sliding part includes a sliding shaft 14, and the limiting part includes a sliding groove 15. The sliding shaft 14 is equipped in the sliding groove 15 and moves along the sliding groove 15. The sliding groove 151 extends straight along the axial direction perpendicular to the rotating shaft 111. The sliding groove 15 includes a pair of limiting surfaces parallel to each other. The sliding shaft 14 is arranged between the pair of limiting surfaces. The sliding shaft 14 slides along the sliding groove 15. The sliding groove 15 can be a through hole or a blind hole. The longitudinal section of the sliding groove 15 can be waist-shaped. The width between the pair of limiting surfaces is equal to or slightly larger than the diameter of the sliding shaft 14, and the sliding shaft 14 slides between the pair of limiting surfaces.

[0044] In addition, the sliding shaft 14 can also be replaced with a block shape, and the sliding groove 15 is set to a shape matching the block shape to limit the movement of the sliding part of the block shape.

[0045] The cabinet hinge seat 11 also includes a pair of side walls 112 arranged opposite to each other, and the pair of side walls 112 are respectively provided with sliding grooves 15, that is, a pair of sliding grooves 15 are also provided, and the pair of sliding grooves 15 correspond to the pair of side walls 112 one by one, and the side walls 112 are respectively arranged at the opposite ends of the cabinet connecting plate 113, and the pair of side walls 112 are relatively parallel. Correspondingly, the sliding grooves 15 on each side wall 112 are also correspondingly parallel to each other, and the axial ends of the sliding shaft 14 are respectively connected to the pair of sliding grooves 15, so that the sliding shaft 14 moves on the sliding grooves 15 of the mutually parallel side walls 112, ensuring that the sliding shaft 14 is always parallel to the cabinet connecting plate 113 and the rotating shaft 111 during the movement.

[0046] Furthermore, the elastic support member 16 includes a support rod 161, and an end of the support rod 161 connected to the sliding shaft 14 is provided with an open groove 1611, and the sliding shaft 14 is supported in the groove 1611, and the opening faces the sliding shaft 14. During the movement of the sliding shaft 14, if a sudden change occurs, such as different changes in the forces between multiple elastic support members 16, or unequal sizes or directions, the sliding part on the side with greater force can have a tendency to move away from the support rod 161 from the opening at the end of the support rod 161, thereby avoiding interference between multiple elastic support members 16, making the degree of freedom less than 1, and facilitating assembly.

[0047] The elastic support member 16 further includes an elastic member 162 sleeved on the outside of the support rod 161 . A limiting protrusion is further provided at one end of the support rod 161 close to the connecting member 13 . The elastic member 162 is supported between the cabinet hinge seat 11 and the limiting protrusion.

[0048] In this embodiment, the elastic member 162 is configured as a spring, and the spring is always in a compressed state. Since the displacement of the movement of the sliding part is not large relative to the size of the hinge 1, by adjusting the elastic coefficient and size of the spring, the spring is always in a compressed state during the sliding of the sliding part along the limiting part. When any one of the multiple support rods 161 tends to move away from the sliding part, the spring restores its deformation, and the elastic force drives the support rod 161 to continue to resist the sliding part, and the support rod 161 will not completely separate from the sliding part, thereby ensuring that the hinge 1 will not fail or be damaged during movement. In addition, during the opening of the door body 3, the compressed spring gradually restores its deformation, providing support force for the opening of the door body 3, forming an auxiliary opening function for the door body 3, which can save effort in opening the door.

[0049] like Figure 4 or Figure 5As shown, the support seat 114 of this embodiment is horizontally arranged between a pair of side walls 112, and a plurality of openings corresponding to the number of elastic support members 16 are arranged on the support seat 114. Each support rod 161 passes through the opening corresponding to it and can move up and down relative to the support seat 114, but never escapes from the opening. Under the elastic action of the spring, the support rod 161 can move with the extension and contraction of the spring. Since one end of the support rod 161 moves linearly with the sliding part and the other end is inserted into the opening, the support rod 161 can only move in a straight line. Combined with the above description, the preferred scheme of this embodiment limits the movement of the sliding shaft 14 to linear up and down movement on a plane parallel to the cabinet connecting plate 113.

[0050] Furthermore, the door hinge seat 12 rotates around the rotating shaft 111, and the door hinge seat 12 includes a door connecting plate 122, a pair of side plates 123 arranged opposite to each other, and a swinging shaft 121 parallel to the rotating shaft 111. The door connecting plate 122 is connected to the door body 3, a pair of side plates 123 are connected to the left and right ends of the door connecting plate 122 and are located on the same side of the door connecting plate 122, a pair of side plates 123 are located between a pair of side walls 112 and correspond one to one with the pair of side walls 112, and the connecting member 13 is pivotally connected to the sliding shaft 14 and the swinging shaft 121 at the same time, and the sliding shaft 14 is also parallel to the swinging shaft 121, that is, the three shafts are parallel to each other. When the door hinge seat 12 flips around the rotating shaft 111, it drives the sliding shaft 14 to move and is always parallel to the rotating shaft 111 under the restrictions of various components.

[0051] The swing shaft 121 is connected to a pair of side plates 123, and the swing shaft 121 is located between a pair of side walls 112, that is, the swing shaft 121 is not connected to the cabinet hinge seat 11, and the arc groove provided on the cabinet hinge seat 11 in the prior art is eliminated, thereby avoiding the hinge 1 being limited by the size and pressure-bearing strength of the arc groove, and the thickness of the hinge 1 can be thinned, thereby increasing the packing volume during storage and transportation and reducing the occupied space during use.

[0052] Through holes are respectively provided at both ends of the connecting member 13, and the swing shaft 121 and the sliding shaft 14 pass through the through holes respectively, so that the connecting member 13 is always pivotally connected with the swing shaft 121 and the sliding shaft 14. When the swing shaft 121, the connecting member 13 and the sliding shaft 14 move, relative rotation can occur between the three.

[0053] Furthermore, the door hinge seat 12 has an opening position for opening the door body 3 and a closing position for closing the door body 3. When the door hinge seat 12 is in the opening position, the axis of the swing shaft 121 is located on the plane where the cabinet connecting plate 113 is located, or the swing shaft 121 is located on the side of the cabinet connecting plate 113 facing the cabinet 2.

[0054] like Figure 2 and Figure 3As shown, a cavity 100 is formed between the door body 3 and the cabinet body 2, and the door body 3 includes a closed state and an open state. When the door body 3 is switched from the closed state to the open state, the swing shaft 121 moves to the cavity 100. There is always a distance between the swing shaft 121 and the door body 3 and the cabinet body 2. Generally, a door seal 4 needs to be provided between the door body 3 and the cabinet body 2. There is a cavity 100 between the door body 3, the cabinet body 2 and the door seal 4. When the swing shaft 121 swings, it moves from the inside of the hinge 1 to the position of the cavity 100. By adjusting the height of the hinge 1 according to the position of the cavity 100, the swing shaft 121 will not interfere with other structures of the refrigerator. In this way, the swing of the swing shaft 121 will not swing excessively because the sliding groove 15 has limited the sliding shaft 14, and the arc groove of the traditional hinge 1 does not need to be provided. Moreover, the swing of the swing shaft 121 does not occupy the space inside the hinge 1, but utilizes the cavity 100 of the refrigerator itself, so that the thickness of the hinge 1 can be further made thinner.

[0055] See also Figure 7 Furthermore, during the movement of the door hinge seat 12 from the door closing position to the door opening position, the connecting member 13 and the cabinet connecting plate 113 do not interfere with each other. The door hinge seat 12 includes a bottom plate abutting against the door body 3. Specifically, this can be achieved by setting the distance between the bottom plate and the door connecting plate 122, so that the swing shaft 121 can be smoothly swung from the inside of the hinge 1 to the position of the cavity 100, so that the thickness of the hinge 1 can be further made thinner.

[0056] See also Figure 3 The portion of the connecting member 13 between the swing shaft 121 and the sliding shaft 14 is recessed in a direction away from the cabinet 2 to further prevent the connecting member 13 from interfering with the cabinet connecting plate 113 during the movement of the door hinge seat 12 from the closed position to the open position.

[0057] Further, see Figure 3 as well as Figures 5 to 7 The plane formed by the axis of the rotating shaft 111 and the sliding shaft 14 is parallel to the cabinet connecting plate 113 .

[0058] The hinge 1 includes a tightened state and a released state. When the hinge 1 is in the tightened state, the spring is in a state of maximum elastic force, and the door body 3 of the corresponding refrigeration device is closed; when the hinge 1 is in the released state, the spring recovers some deformation and is in a state of minimum elastic force, and the door body 3 of the corresponding refrigeration device is opened. In the process of the hinge 1 switching from the tightened state to the released state, the rotating shaft 111 and the sliding shaft 14 are always located in the same plane, the swing shaft 121 swings away from the plane, and the sliding shaft 14 slides along the sliding groove 15 toward the rotating shaft 111.

[0059] Further, see Figure 3 and Figure 6When the hinge 1 is in the tightened state and the door hinge seat 12 is in the closed position, the axis of the swing shaft 121 is located on the plane formed by the axes of the rotating shaft 111 and the sliding shaft 14. In this way, the thickness of the hinge 1 can be set to the thinnest, further increasing the packing volume of the refrigeration equipment during transportation.

[0060] Furthermore, in this embodiment, the hinge 1 further includes a sleeve 17 sleeved on the outside of the sliding shaft 14, the sleeve 17 is arranged between the support rod 161 and the sliding groove 15, the support rod 161 is arranged between the sleeve 17 and the connecting member 13, and the sleeve 17 limits the left and right movement of the support rod 161. Figure 4 As shown, the connecting member 13 can extend two legs, which are respectively arranged on both sides of the support rod 161, and a shaft sleeve 17 is respectively arranged on the left and right sides of the sliding shaft 14. The hinge 1 is a left-right symmetrical structure.

[0061] Furthermore, the hinge 1 also includes a cover plate, which encapsulates the hinge 1 and forms an outer surface of the hinge 1, thereby improving the aesthetics of the refrigeration device.

[0062] In other embodiments, the limiting portion may also be provided on the cover plate, and the sliding portion cooperates with the limiting portion and moves linearly along the limiting portion, thereby limiting the movement direction of the elastic support member 16 to be parallel to the cabinet connecting plate 113 and fixing the movement direction.

[0063] See also Figure 8 In a variant embodiment, the cabinet hinge seat 11 also has a pair of arc grooves 115 arranged opposite to each other, and the pair of arc grooves 115 are respectively arranged on a pair of side walls 112. The swing shaft 121 is matched in the pair of arc grooves 115 and swings back and forth along the arc grooves 115. The arc grooves 115 can limit the rotation angle of the door hinge seat 12 relative to the cabinet hinge seat 11, thereby limiting the opening angle of the door body 3 relative to the cabinet body 2 and making the door body 3 hover.

[0064] Likewise, a plurality of elastic supporting members 16 may be provided.

[0065] The arc groove 115 has a proximal end close to the sliding groove 15 and a distal end away from the sliding groove 15, and the sliding groove 15 has an extreme proximal end close to the arc groove 115 and an extreme distal end away from the arc groove; when the swing shaft 121 swings to the proximal end, the door body 3 is in a closed state, and when the swing shaft 121 swings to the distal end, the door body 3 is in an open state and hovers.

[0066] Furthermore, when the swing shaft 121 swings to the distal end, there is a gap between the sliding shaft 14 and the extreme proximal end, and the elastic support member 16 has a compression deformation. In this way, when an external force is applied to make the door hinge seat 12 rotate with the door body 3 to the door opening position, due to the existence of the gap between the sliding shaft 14 and the extreme proximal end, the elastic support member 16, under the action of its elastic restoring force, applies an upward thrust to the connecting member 13, which is transmitted to the swing shaft 121 to form a force that drives the swing shaft 121 to move toward the distal end, so that the door hinge seat 12 has a tendency to rotate outward around the rotating shaft 111. Even after the external force is removed, the thrust can be balanced with the gravity of the door body 3, so that the door body 3 is suspended at the set maximum door opening angle, solving the problem of the door body 3 rebounding after the external force is removed.

[0067] Compared with the prior art, the present embodiment has the following beneficial effects: the sliding portion drives the elastic support member 16 to move in a straight line, so that the hinge 1 of the present embodiment is different from the swinging movement of the elastic support member in the traditional hinge. On the one hand, the sliding portion greatly reduces the activity space required for the elastic support member 16 inside the hinge 1, avoiding the problem that the elastic support member 16 swings back and forth and occupies a large amount of space, and the arc groove provided on the cabinet hinge seat 11 in the traditional hinge is eliminated, avoiding the hinge 1 being limited by the size and pressure bearing strength of the arc groove, so that the hinge 1 can be made very thin without affecting the strength of the hinge 1 structure, thereby increasing the The packing volume during storage and transportation is increased, and the occupied space during use is reduced; on the other hand, a plurality of elastic support members jointly share the supporting function of the door hinge seat 12 and the door body 3, which can reduce the strength requirement of each elastic support member, thereby making the outer diameter of each elastic support member smaller and further reducing the thickness of the hinge 1; in addition, by the movement of the limiting portion in the sliding portion, the sliding portion can be used to limit the opening angle of the door body 3 relative to the cabinet body 2, and when the limiting portion moves to one end of the sliding portion close to the door hinge seat 12, the door body 3 opens to the maximum opening angle and hovers under the restriction of the sliding portion.
