[0034] See also Figure 1 A refrigeration device 100 provided in an embodiment of the present invention comprises a hinge 1, a cabinet 2 and a door 3. The cabinet 2 has a refrigeration compartment for storing and refrigerating items. The door 3 is assembled to the cabinet 2 and can be rotated relative to the cabinet 2 through the hinge 1 to open or close the refrigeration compartment. The refrigeration device 100 can be specifically configured as a refrigerator, a freezer, a wine cabinet, etc.

[0035] Combination Figures 2 to 8 The hinge 1 includes a fixed hinge seat 11 and a movable hinge seat 12 rotatably connected to the fixed hinge seat 11, the fixed hinge seat 11 includes a pivot shaft 113, the movable hinge seat 12 is rotatably connected to the pivot shaft 113 so that the movable hinge seat 12 rotates relative to the fixed hinge seat 11, wherein the fixed hinge seat 11 is assembled on the cabinet 2, and the movable hinge seat 12 is assembled on the door body 3, and the movable hinge seat 12 rotates relative to the fixed hinge seat 11 to drive the door body 3 to rotate relative to the cabinet body 2 to open or close the refrigeration compartment.

[0036] The fixed hinge seat 11 includes a bottom plate 111 abutting against the outer wall of the cabinet 2 and a pair of side plates 112 arranged opposite to each other, the bottom plate 111 has a first end 1111 and a second end 1112 arranged opposite to the first end 1111 along a first direction, the pair of side plates 112 are respectively connected to the opposite ends of the bottom plate 111 along a second direction perpendicular to the first direction, the pair of side plates 112 are arranged on the same side of the bottom plate 111, and an assembly space is formed between the pair of side plates 112 and the bottom plate 111. Preferably, the pair of side plates 112 extend perpendicularly to the base plate 121 in a direction away from the bottom plate 111.

[0037] Both ends of the pivot shaft 113 are fixedly connected to a pair of side plates 112 , respectively, and the axis of the pivot shaft 113 extends along the second direction.

[0038] The movable hinge seat 12 includes a base plate 121 abutting against the door body 3 and a pair of side edges 122 arranged oppositely along the second direction, the pair of side edges 122 are respectively connected to the opposite ends of the base plate 121 along the second direction, the pair of side edges 122 are relatively arranged on the same side of the base plate 121, the pair of side edges 122 are arranged between the pair of side plates 112 and correspond one-to-one with the pair of side plates 112, the pair of side edges 122 are respectively pivotally connected to the pivot shaft 113 and can enable the movable hinge seat 12 to rotate around the pivot shaft 113 relative to the bottom plate 111.

[0039] Further, the side edge 122 is parallel to the side plate 112. Preferably, the side edge 122 extends perpendicularly to the base plate 121 in a direction away from the door body 3, and the side plate 112 extends perpendicularly to the bottom plate 111 in a direction away from the side wall of the cabinet body 2.

[0040] For ease of description, in this embodiment, the refrigeration equipment 100 is placed horizontally on the ground as an example for description. When the door body 3 is closed, the direction from the door body 3 to the cabinet body 2 is defined as the top-to-bottom direction. Correspondingly, the movable hinge seat 12 is located above the fixed hinge seat 11. The side of the hinge 1 facing the refrigeration equipment 100 is defined as the inside, and the side of the hinge 1 away from the refrigeration equipment 100 is defined as the outside. When the user faces the hinge 1 from the outside, the two sides of the hinge 1 are respectively defined as left and right.

[0041] In this embodiment, the first direction is the up and down direction, and the second direction is the left and right direction. The fixed hinge seat 11 includes a bottom plate 111 extending up and down and a pair of side plates 112 arranged opposite to each other on the left and right. The pair of side plates 112 are respectively connected to the left and right ends of the bottom plate 111 and extend outward perpendicular to the bottom plate 111; the pivot shaft 113 extends along the left and right directions; the movable hinge seat 12 includes a base plate 121 abutting against the door body 3 and a pair of side edges 122 arranged opposite to each other on the left and right directions. The base plate 121 can rotate relative to the base plate 111 in the left and right directions. The pair of side edges 122 are respectively connected to the left and right ends of the base plate 121 and extend outward perpendicular to the base plate 121.

[0042] The movable hinge seat 12 has an open position for opening the door body 3 and an initial position for closing the door body 3 . In the initial position, the base plate 121 also extends in the up-down direction, that is, the base plate 121 is parallel or coplanar with the bottom plate 111 . Figure 4 The movable hinge seat 12 is shown in the initial position. Fig. 9 The state of the movable hinge seat 12 in the door opening position is shown. The door opening position here is defined as the position of the movable hinge seat 12 relative to the fixed hinge seat 11 when the door body 3 is opened to a set maximum angle, and the maximum angle is usually set to 81° to 88° when the door body 3 is flipped open.

[0043] Furthermore, the movable hinge seat 12 includes a swing shaft 123, which is parallel to the pivot shaft 113. The fixed hinge seat 11 has a pair of arc grooves 13 arranged opposite to each other. The two ends of the swing shaft 123 pass through a pair of side edges 122 respectively and are connected to the pair of arc grooves 13. The swing shaft 123 swings along the arc groove 13, and the end of the arc groove 13 limits the rotation angle of the movable hinge seat 12 relative to the fixed hinge seat 11, thereby limiting the maximum opening angle of the door body 3 relative to the cabinet body 2 and causing the door body 3 to hover.

[0044] Furthermore, the hinge 1 also includes a connecting member 14, a sliding mechanism 15 and an elastic member 17. The connecting member 14 is pivotally connected to the swing shaft 123 to achieve a pivotal connection between the connecting member 14 and the movable hinge seat 12. The fixed hinge seat 11 is provided with a limiting groove 124. The sliding mechanism 15 includes a matching portion 152. The matching portion 152 is matched in the limiting groove 124 and can make a linear motion along the limiting groove 124, so that the sliding mechanism 15 makes a linear motion along the limiting groove 124. The upper end of the connecting member 14 is pivotally connected to the swing shaft 123, and the lower end of the connecting member 14 is pivotally connected to the sliding mechanism 15, so that the connecting member 14 is pivotally connected to the swing shaft 123 and the sliding mechanism 15 and drives the sliding mechanism 15 to make a linear motion along the limiting groove 124. The elastic member 17 is located in the assembly space, one end of the elastic member 17 is connected to the sliding mechanism 15 and moves synchronously with the sliding mechanism 15, and the other end of the elastic member 17 abuts against the hinge seat 11. When the movable hinge seat 12 moves between the door opening position and the initial position, the elastic member 17 is always in a compressed state.

[0045] In this way, when the movable hinge seat 12 rotates around the pivot axis 113 relative to the fixed hinge seat 11, the swing axis 123 swings accordingly and pulls the connecting member 14 to drive the sliding mechanism 15 to move together, and during the movement process, under the mutual restriction of various components, the swing axis 123 and the pivot axis 113 are always in a parallel state, and the movable hinge seat 12, the pivot axis 113, the swing axis 123, the connecting member 14, the sliding mechanism 15, the elastic member 17 and the fixed hinge seat 11 together constitute a crank slider mechanism, which converts the pivoting movement of the movable hinge seat 12 into a linear movement of the sliding mechanism 15 and the elastic member 17. Compared with the arc movement of the sliding mechanism 15 and the elastic member 17, the activity space required for the movement of the elastic member 17 is greatly reduced, and when the movable hinge seat 12 is in the initial position, the elastic restoring force of the elastic member 17 provides support force for the connecting member 14 and the swing axis 123, and the support force is applied to the swing axis 123 along the tangential component of the arc groove 13, so as to achieve the effect of saving effort in opening the door.

[0046] The sliding mechanism 15 also includes a movable shaft 151, which is parallel to the pivot shaft 113. The limiting groove 124 extends along the first direction, that is, extends up and down. The matching portion 152 can move up and down along the limiting groove 124, so that the sliding mechanism 15 moves up and down along the extension direction of the limiting groove 124. The upper end of the connecting member 14 is pivotally connected to the swing shaft 123, and the lower end of the connecting member 14 is pivotally connected to the movable shaft 151, so that the connecting member 14 is pivotally connected to the swing shaft 123 and the sliding mechanism 15 and drives the matching portion 152 to move up and down along the limiting groove 124.

[0047] Further, the arc groove 13 has a proximal end close to the elastic member 17 and a distal end away from the elastic member 17. When the swing shaft 123 swings to the proximal end, the movable hinge seat 12 is in the initial position and the door body 3 is in a closed state; when the swing shaft 123 swings to the distal end, the movable hinge seat 12 is in the door opening position and the door body 3 is in an open state. The limit groove 124 has a limit proximal end 1241 close to the arc groove 13 and a limit distal end 1242 away from the arc groove 13; when the swing shaft 123 swings to the proximal end, the matching portion 152 moves to the limit distal end 1242; when the swing shaft 123 swings to the distal end, there is a gap between the matching portion 152 and the limit proximal end 1241, and the elastic member 17 has a compression deformation amount.

[0048] In actual application, when the door body 3 is opened until the swing shaft 123 swings to the far end under the action of external force, the door body 3 is opened to the set maximum door opening angle. When the external force is removed, under the action of the door body 3's own gravity, due to the inevitable matching gaps between the pivot shaft 113, the swing shaft 123 and the various components rotatably connected thereto, the door body 3 will have a certain angle of rebound to maintain balance and hover. In other words, it is difficult for the door body 3 to hover at the set maximum door opening angle.

[0049] When the swing shaft 123 is swung to the distal end, there is a gap between the matching portion 152 and the extreme proximal end 1241, and the elastic member 17 has a compression deformation. In this way, when an external force is applied to cause the movable hinge seat 12 to rotate with the door body 3 to the door opening position, due to the existence of the gap between the matching portion 152 and the extreme proximal end 1241, the elastic member 17, under the action of its elastic restoring force, applies an upward thrust to the connecting member 14, which is transmitted to the swing shaft 123 to form a force in which the connecting member 14 drives the swing shaft 123 to move toward the distal end, thereby making the movable hinge seat 12 tend to rotate outward around the pivot axis 113. Even after the external force is removed, the thrust can be balanced with the gravity of the door body 3, thereby making the door body 3 hover at the set maximum door opening angle, solving the problem of the door body 3 rebounding after the external force is removed.

[0050] Specifically, a pair of arc-shaped grooves 13 are respectively provided on a pair of side plates 112 .

[0051] See also Figures 2 to 5 In this embodiment, the limiting groove 124 is arranged on the side plate 112. Preferably, a pair of limiting grooves 124 are arranged, and the pair of limiting grooves 124 are respectively arranged on a pair of side plates 112 on the left and right sides, and the matching parts 152 are the axial ends of the movable shaft 151, that is, the axial ends of the movable shaft 151 are respectively matched in a pair of limiting grooves 124.

[0052] See also Figure 6 to Figure 7 In other embodiments, the limiting groove 124 may also be disposed on the bottom plate 111 , and the matching portion 152 is connected to the movable shaft 151 and protrudes toward the bottom plate 111 .

[0053] See also Figure 3 and Figure 5 Furthermore, the elastic member 17 includes a connecting rod 171 and a spring 172 sleeved on the outer circumference of the connecting rod 171, one end of the connecting rod 171 is connected to the sliding mechanism 15, and the end of the connecting rod 171 away from the sliding mechanism 15 is inserted into the fixed hinge seat 11 and loosely connected to the fixed hinge seat 11, that is, the connecting rod 171 can move up and down relative to the fixed hinge seat 11, and the other end of the spring 172 away from the sliding mechanism 15 presses against the fixed hinge seat 11.

[0054] Furthermore, the elastic member 17 further includes a limiting portion 1711 disposed on the connecting rod 171 , one end of the spring 172 close to the sliding mechanism 15 abuts against the limiting portion 1711 , and one end of the spring 172 away from the sliding mechanism 15 abuts against the hinge seat 11 .

[0055] Furthermore, the limiting portion 1711 is a gasket coaxially arranged with the spring 172 , and the diameter of the gasket is larger than the outer diameter of the spring 172 , so that the gasket can effectively resist the spring 172 to prevent the spring 172 from failing.

[0056] Furthermore, the fixed hinge seat 11 also includes a baffle 114 arranged at one end thereof away from the movable hinge seat 12, and the two ends of the baffle 114 are respectively connected to a pair of side plates 112, and the baffle 114 has a slot, and the end of the connecting rod 171 away from the sliding mechanism 15 is inserted into the slot, thereby limiting the elastic member 17 to only move parallel to the bottom plate 111, that is, move up and down, and avoid increasing the thickness of the hinge 1; in this embodiment, the lower end of the spring 172 abuts against the baffle 114, the connecting rod 171 is loosely connected to the baffle 114, and when the elastic member 17 moves up and down synchronously with the movable shaft 151, the lower end of the connecting rod 171 always protrudes out of the baffle 114, which can prevent the elastic member 17 from escaping from the baffle 114 and causing the elastic member 17 to fail.

[0057] See also Figures 2 to 3 Furthermore, in this embodiment, the hinge 1 further comprises a limit block 16, which can be detachably assembled in the limit slot 124, and has an assembled state in which the limit block 16 is assembled in the limit slot 124, and a free state in which the limit block 16 is separated from the limit slot 124. When the limit block 16 is in the assembled state, the movable hinge seat 12 is in the initial position, one end of the limit block 16 abuts against the extreme proximal end 1241, and the other end of the limit block 16 abuts against the matching portion 152 and makes the matching portion 152 abut against the extreme distal end 1242; when the limit block 16 is in the free state, the connecting member 14 can drive the sliding mechanism 15 to perform linear motion along the limit slot 124.

[0058] In this way, during the transportation of the hinge 1 or when the hinge 1 is assembled to the refrigeration equipment 100, the limit block 16 can be assembled in the limit groove 124, so as to prevent the fixed hinge seat 11 from flipping back and forth relative to the movable hinge seat 12 and causing damage to the hinge 1; in addition, when installing, the on-site workers can prevent the movable hinge seat 12 from flipping back and forth by assembling the limit block 16 in the limit groove 124, and can fix the movable hinge seat 12 to the door body 3 for installation without holding the movable hinge seat 12 by hand, which greatly improves the installation efficiency and reduces the labor cost. When the installation is completed, the limit block 16 can be removed from the limit groove 124, so that the limit block 16 is separated from the limit groove 124, and the sliding mechanism 15 and the elastic member 17 can move along the limit groove 124, so that the movable hinge seat 12 can rotate relative to the fixed hinge seat 11.

[0059] See also Figures 4 to 6In other embodiments, the above effect can also be achieved by setting a locking member 19 that can be detachably assembled on the sliding mechanism 15 or the elastic member 17 and fixed to the fixed hinge seat 11. Specifically, the hinge 1 also includes a locking member 19 for fixing the sliding mechanism 15 or the elastic member 17 to the fixed hinge seat 11, that is, when the locking member 19 is assembled on the fixed hinge seat 11, the locking member 19 can limit the movement of the sliding mechanism 15 and the elastic member 17 relative to the fixed hinge seat 11. Among them, the locking member 19 can be set as a rod-shaped member, and the connecting rod 171 or the sliding mechanism 15 is provided with a through hole. The locking member 19 passes through the through hole and a pair of side plates 112, or the locking member 19 passes through the through hole and the bottom plate 111, or the locking member 19 passes through the through hole and abuts against one end of the baffle 114 away from the spring 172 to limit the movement of the sliding mechanism 15 and the elastic member 17 relative to the fixed hinge seat 11. The through hole may be disposed between the limiting portion 1711 and the connecting member 14 , or may be disposed on the side of the connecting rod 171 that is located on the baffle 114 away from the spring 172 .

[0060] In this embodiment, one elastic member 17 is provided; in other embodiments, multiple elastic members 17 may be provided according to actual needs. Figure 8 As shown, a pair of elastic members 17 are arranged at intervals, and the pair of elastic members 17 are respectively arranged on the left and right sides of the connecting member 14. Multiple elastic members 17 can share the force, so that the size of the elastic member 17 can be reduced. If the elastic member 17 includes a spring 172, the outer diameter and wire diameter of the spring 172 can be reduced, so that the thickness of the hinge 1 can be further reduced.

[0061] See also Figure 3 and Figure 5 Furthermore, the hinge 1 also includes a sleeve 18, which is sleeved on the outer periphery of at least one of the swing shaft 123, the movable shaft 151, and the pivot shaft 113. The sleeve 18 includes a sleeve 181 and an oil storage rib 182 arranged on the inner wall of the sleeve 181. In this way, lubricating oil can be added between the oil storage ribs 182, and the lubricating oil can slowly seep out from the sleeve 18 to the swing shaft 123, the movable shaft 151, and the pivot shaft 113, thereby playing a lubricating and protective role on the swing shaft 123, the movable shaft 151, and the pivot shaft 113, so that the hinge 1 rotates smoothly, reduces wear and noise during use, and extends the service life of the hinge 1 and the refrigeration equipment 100.

[0062] The sleeve 181 may be provided in a cylindrical shape. Figures 9 and 10Preferably, the cross section of the sleeve 181 is arc-shaped, and the central angle thereof is 270-280°. Thus, by setting the sleeve 181 in a semi-enclosed opening structure, the sleeve 18 can be directly clamped to the swing shaft 123 and the movable shaft 151 in the radial direction, which not only improves the assembly efficiency, but also is not restricted by the assembly sequence, thus avoiding the trouble of disassembling and reassembling all the components when the assembly sequence is wrong.

[0063] Furthermore, the oil storage ribs 182 extend axially along the sleeve 181, and at least two oil storage ribs 182 are provided, and at least two oil storage ribs 182 are evenly arranged along the circumference of the sleeve 181, both of which can slow down the rate of lubricating oil seeping from the sleeve 18, avoiding excessive overflow of lubricating oil causing the hinge 1 to become dirty and requiring frequent addition of lubricating oil.

[0064] Furthermore, the connecting member 14 includes a pair of first connecting ends 141 connected to the movable shaft 151, and the outer periphery of the movable shaft 151 is provided with a sleeve 18, the sleeve 18 is located between the pair of first connecting ends 141, and the axial ends of the sleeve 18 respectively abut against the pair of first connecting ends 141, thereby limiting the axial movement of the connecting member 14 along the movable shaft 151.

[0065] The elastic member 17 includes a connecting end 173 connected to the movable shaft 151. Here, the sleeve 18 sleeved on the outer periphery of the movable shaft 151 can be divided into two sub-sleeves. The connecting end 173 is located between the two sub-sleeves and respectively abuts against the two sub-sleeves, thereby limiting the axial movement of the elastic member 17 along the movable shaft 151.

[0066] Similarly, the outer periphery of the swing shaft 123 may also be sleeved with a sleeve 18. The connecting member 14 includes a pair of second connecting ends 142 connected to the swing shaft 123. Specifically, the sleeve 18 may be disposed between the pair of second connecting ends 142, and the axial ends of the sleeve 18 respectively abut against the pair of second connecting ends 142 to limit the axial movement of the connecting member 14 along the swing shaft 123; or, the sleeve 18 may be disposed between the second connecting end 142 and the side edge 122 corresponding to the second connecting end 142, and the two abut against the axial ends of the sleeve 18 respectively, to limit the axial movement of the connecting member 14 along the swing shaft 123.

[0067] In this embodiment, the swing shaft 123 is provided with one; see Figure 8 In other embodiments, the number of swing shafts 123 may also be two, the two swing shafts 123 are respectively connected to a pair of second connecting ends 142 , and the two swing shafts 123 are coaxially arranged.

[0068] See also Figures 2 to 5Furthermore, when the movable hinge seat 12 is in the initial position, the swing shaft 123 is located at the proximal end of the arc groove 13, and in the third direction perpendicular to the first direction and the second direction, that is, the inside-outside direction, the axis of the swing shaft 123 is located between the axis of the pivot shaft 113 and the axis of the movable shaft 151, so that a pre-opening force can be provided to the door body when opening the door, making the door opening effortless.

[0069] See also Figure 5 Furthermore, the elastic member 17 has a connecting end 173 connected to the movable shaft 151, and a groove 1731 is formed at one end of the connecting end 173 facing the movable shaft 151. The movable shaft 151 is clamped in the groove 1731, and the elastic member 17 resists the movable shaft 151 to limit the movable shaft 151 from escaping from the groove 1731.

[0070] Preferably, the shaft sleeve 18 is provided with a mounting groove 183 , and the connecting end 173 is snap-fitted into the mounting groove 183 to limit the axial movement of the elastic member 17 along the movable shaft 151 .

[0071] See also Fig.11 Furthermore, in other embodiments, the movable shaft 151 also includes a pair of fixing portions 1511 spaced apart along its axial direction, and an assembly groove 1512 is formed between the pair of fixing portions 1511. The elastic member 17 has a connecting end 173 connected to the movable shaft 151, and the connecting end 173 is matched with the assembly groove 1512. The connecting end 173 at opposite ends along the axial direction of the movable shaft 151 respectively abuts against the pair of fixing portions 1511 to limit the axial movement of the elastic member 17 along the movable shaft 151.

[0072] Compared with the prior art, the hinge 1 provided by the present invention and the refrigeration equipment 100 having the same have the following beneficial effects: the arc groove 13 is provided to limit the rotation angle of the movable hinge seat 12 relative to the fixed hinge seat 11, thereby limiting the door opening angle of the door body 3 and making the door body 3 hover after opening the door opening angle; the limit block 16 is detachably assembled in the limit groove 124 or the locking member 19 is detachably assembled on the sliding mechanism 15 or the elastic member 17 and fixed to the fixed hinge seat 11, so that the hinge 1 can be prevented from being transported or assembled in the refrigeration equipment 100. The fixed hinge seat 11 flips back and forth relative to the movable hinge seat 12 and causes damage to the hinge 1. During installation, the on-site workers do not need to hold the movable hinge seat 12 with their hands to fix the movable hinge seat 12 to the door body 3 for easy installation, which greatly improves the installation efficiency and reduces the labor cost. When the movable hinge seat 12 rotates relative to the fixed hinge seat 11 around the swing shaft 123, the swing shaft 123 swings accordingly and pulls the connecting member 14 to drive the movable shaft 151 to move together. In addition, during the movement, under the mutual restriction of various components, the swing shaft 123, the movable shaft 151 and the pivot shaft 1 13 are always in a parallel state, and the movable hinge seat 12, the pivot shaft 113, the swing shaft 123, the connecting member 14, the movable shaft 151, the elastic member 17 and the fixed hinge seat 11 together constitute a crank slider mechanism, which converts the pivoting motion of the movable hinge seat 12 into the linear motion of the elastic member 17. When the movable hinge seat 12 is in the initial position, the elastic restoring force of the elastic member 17 provides a supporting force for the connecting member 14 and the swing shaft 123, and the supporting force is applied to the swing shaft 123 along the tangential component of the arc groove 13, so as to achieve the effect of saving effort in opening the door; through the shaft The sleeve 18 is sleeved on the outer periphery of at least one of the swing shaft 123, the pivot shaft 113 and the movable shaft 151, and the oil storage ribs 182 are arranged on the inner wall of the sleeve 181. Lubricating oil can be added between the oil storage ribs 182. The lubricating oil can slowly seep out from the sleeve 18 to the swing shaft 123, the movable shaft 151 and the pivot shaft 113, thereby playing a role in lubricating and protecting the swing shaft 123, the movable shaft 151 and the pivot shaft 113, making the hinge 1 rotate smoothly, reducing wear and noise during use, and extending the service life of the hinge 1 and the refrigeration equipment 100.
