[0040] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0042] Combination Figures 1 to 6 , the embodiment of the present disclosure provides a hinge device 100 for hingedly connecting the cabinet and door of a refrigerator. The hinge device 100 includes a first mounting portion 110, a second mounting portion 120, a hinge assembly and a stopper 140. The first mounting portion 110 is used to be fixedly connected to the cabinet of the refrigerator, and the first mounting portion 110 is provided with a first sliding groove 111. The second mounting portion 120 is used to be fixedly connected to the door of the refrigerator. The hinge assembly is used to hinge the first mounting portion 110 and the second mounting portion 120. The hinge assembly includes a first connecting rod 131, and the first end of the first connecting rod 131 is slidably disposed in the first sliding groove 111. The stopper 140 is detachably disposed in the first sliding groove 111 and is located on a side close to the door body rotation axis, and is used to prevent the first end of the first connecting rod 131 from continuing to move toward the door body rotation axis side, so that the door body stops after opening the first set angle.

[0043] In the disclosed embodiment, the first set angle is the maximum angle at which the door of the refrigerator will not collide with the wall of the deep and narrow space when it is opened.

[0044] Specifically, the first mounting portion 110 has a first accommodating cavity. One side of the first accommodating cavity is an open structure, and a plurality of mounting holes are provided on the side wall opposite to the open side. The first mounting portion 110 is fixedly mounted to the refrigerator body through the plurality of mounting holes.

[0045] Specifically, the hinge assembly is composed of a plurality of connecting rods, and is used to hinge the first mounting portion 110 and the second mounting portion 120. Specifically, the hinge assembly 130 includes a first connecting rod 131, and a first end of the first connecting rod 131 is slidably disposed in the first sliding groove 111.

[0046] Alternatively, if Figure 1 As shown, the first sliding groove 111 is in the shape of an inclined long strip hole and is symmetrically arranged on the upper and lower side walls of the first accommodating cavity.

[0047] Specifically, the first end of the first connecting rod 131 extends into the first accommodating cavity through the open side of the first accommodating cavity, and the first end of the first connecting rod 131 is slidably disposed in the first sliding groove 111. Specifically, a through hole is disposed at the first end of the first connecting rod 131, and a rotating shaft is disposed in the through hole, and both ends of the rotating shaft are matched with the first sliding groove 111, so that the first end of the first connecting rod 131 can slide relative to the first sliding groove 111.

[0048] Specifically, the second mounting portion 120 includes a second accommodating cavity, one side of the second accommodating cavity is an open structure, and a plurality of mounting holes are arranged on the side wall opposite to the open side. The second mounting portion 120 is fixedly mounted to the door of the refrigerator through the plurality of mounting holes.

[0049] Specifically, the stopper 140 is detachably disposed in the first sliding groove 111. When the first end of the first connecting rod 131 contacts the stopper 140, the first end of the first connecting rod 131 can be prevented from continuing to move toward the door body axis side, so that the door body stops after opening to the first set angle, thereby preventing the door body from colliding with the wall of the deep and narrow space.

[0050] In the embodiment of the present disclosure, a stopper 140 is detachably provided on one side of the first sliding groove 111 close to the door body rotation axis, so that the first end of the first connecting rod 131 can no longer continue to move along the first sliding groove 111 toward the side of the door body rotation axis after contacting the stopper 140. In this way, the maximum opening angle of the door body can be limited to the first set angle. Since in the embodiment of the present disclosure, the first set angle is the maximum angle at which the door body of the refrigerator will not collide with the wall of the deep and narrow space when it is opened. Therefore, the embodiment of the present disclosure can reduce the risk of the door body of the refrigerator colliding with the wall of the deep and narrow space when it is opened, and reduce the risk of damage to the refrigerator door.

[0051] Alternatively, if Figure 2 As shown, the stopper 140 includes a stopper portion 141 and a connecting portion. The stopper portion 141 is located in the first sliding groove 111. The connecting portion is connected to the stopper portion 141 and is detachably mounted on the first mounting portion 110.

[0052] Specifically, the stopper 141 is located in the first sliding groove 111, and can prevent the first end of the first connecting rod 131 from continuing to slide in the first sliding groove 111. The connecting portion is connected to the stopper 141, and the stopper 140 is installed on the first installation portion 110 through the connecting portion.

[0053] Optionally, the connecting portion and the stopping portion 141 are integrally formed.

[0054] Specifically, the connecting portion and the stopper portion 141 are integrally formed, which can simplify the steps of manufacturing the stopper 140. In this way, the manufacturing cost of the stopper 140 can be reduced.

[0055] Optionally, the connecting portion and the stopping portion 141 are detachably connected.

[0056] Specifically, since the opening angle of the limited door body (i.e., the first set angle) corresponds to the length of the stopper 141, the stopper 141 is detachably connected to the connecting portion, and only the stopper 141 of the stopper 140 can be replaced according to the first set angle, thereby avoiding the need to replace the entire stopper 140.

[0057] Optionally, the length of the stopper 141 corresponds to the first set angle.

[0058] Specifically, since the stopper 141 is located in the first sliding groove 111, and the stopper 141 is used to block the first end of the first connecting rod 131 of the hinge assembly 130, the maximum opening angle of the door body can be limited by adjusting the length of the stopper 141. Therefore, the length of the stopper 141 corresponds to the first set angle.

[0059] For example, the length of the first sliding groove 111 is 47.5 mm. When the first setting angle is 90 degrees, the length of the stopper 141 needs to be set to 8.7 mm. When the first setting angle is 100 degrees, the length of the stopper 141 needs to be set to 4.7 mm. When the first setting angle is 110 degrees, the length of the stopper 141 needs to be set to 2 mm.

[0060] Alternatively, if Figure 1 As shown, the second end of the first connecting rod 131 is rotatably connected to the second mounting portion 120; the hinge assembly 130 also includes a second connecting rod 132 and a third connecting rod 133. The first end of the second connecting rod 132 is rotatably connected to the second mounting portion 120. The first end of the third connecting rod 133 is connected to the second end of the second connecting rod 132, the second end of the third connecting rod 133 is rotatably connected to the first mounting portion 110, and the middle portion of the third connecting rod 133 is rotatably connected to the middle portion of the first connecting rod 131.

[0061] Specifically, through the above connection relationship, when the refrigerator door is closed, the hinge assembly 130 hinged between the first mounting portion 110 and the second mounting portion 120 shrinks. Specifically, the second mounting portion 120, the first connecting rod 131, the second connecting rod 132 and the third connecting rod 133 can be fixed at the hinge point between the third connecting rod 133 and the first mounting portion 110, so that the first end of the first connecting rod 131 slides along the first sliding groove 111 toward the door body axis side, so that the second mounting portion 120 rotates and folds relative to the first mounting portion 110, thereby achieving the closing of the refrigerator door.

[0062] Specifically, through the above connection relationship, when the refrigerator door is opened, the hinge assembly 130 hinged between the first mounting portion 110 and the second mounting portion 120 is extended. Specifically, the second mounting portion 120, the first connecting rod 131, the second connecting rod 132 and the third connecting rod 133 can be fixed at the hinge point between the third connecting rod 133 and the first mounting portion 110, so that the first end of the first connecting rod 131 slides along the first sliding groove 111 away from the door body axis, so that the second mounting portion 120 rotates relative to the first mounting portion 110 and unfolds, thereby realizing the opening of the refrigerator door.

[0063] Specifically, since the first mounting portion 110 has a first accommodating cavity, the first end of the first connecting rod 131 is slidably disposed in the first sliding groove 111, and the second end of the third connecting rod 133 is rotatably connected to the first mounting portion 110. When the door is closed, the first connecting rod 131, the second connecting rod 132 and the third connecting rod 133 can be folded into the first accommodating cavity. In this way, the space occupied by the hinge device 100 is reduced when the refrigerator door is closed, and the sealing performance of the door to the box body is improved.

[0064] In the embodiment of the present disclosure, since the lever arm formed by the hinge assembly 130 through the first connecting rod 131, the second connecting rod 132 and the third connecting rod 133 is relatively long, a wider rotation space can be formed between the refrigerator body and the door body. When the refrigerator door body is opened, a greater distance is formed between the refrigerator body and the door body. Therefore, when the refrigerator adopts the hinge device 100 provided in the embodiment of the present disclosure, the refrigerator door body can be separated from the deep and narrow space, reducing the interference between the door body and the deep and narrow space or other objects when the refrigerator door body is opened, and avoiding the influence on the opening range of the refrigerator door body.

[0065] Optionally, the first link 131, the second link 132, the third link 133, the first mounting portion 110 and the second mounting portion 120 constitute a five-link hinge; or, the first link 131, the second link 132, the third link 133 and the second mounting portion 120 constitute a double rocker mechanism.

[0066] Alternatively, if Figure 1 and Figure 3 As shown, the first mounting portion 110 is further provided with a second sliding groove 112, and the hinge device 100 further includes a rebound assembly 150. The first end of the rebound assembly 150 is fixedly provided on the first mounting portion 110, and the second end of the rebound assembly 150 is slidably provided in the second sliding groove 112, and after the door body is opened to a second set angle, the second end of the rebound assembly 150 abuts against the second end of the third connecting rod 133; wherein the second set angle is smaller than the first set angle.

[0067] Specifically, the second setting angle is smaller than the first setting angle.

[0068] Specifically, the rebound component 150 is an elastic device, and the first mounting portion 110 includes a first accommodating cavity. The first end of the rebound component 150 is fixedly mounted on the first mounting portion 110, and the other end is slidably disposed in a second sliding groove 112 on the side wall of the first accommodating cavity. The second end of the rebound component 150 can slide along the second sliding groove 112 when compressed.

[0069] Specifically, after the door of the refrigerator is opened to the second set angle, the second end of the rebound assembly 150 abuts against the second end of the third connecting rod 133. When the door continues to open, the second end of the rebound assembly 150 is compressed and moved away from the door axis. After the user takes out food from the refrigerator, the door can be automatically closed under the action of the rebound assembly 150.

[0070] In the disclosed embodiment, a rebound assembly 150 is further provided in the first mounting portion 110, so that the door of the refrigerator can be automatically closed under the action of the rebound assembly 150 after the opening angle is greater than the second set angle. This avoids the situation where the user forgets to close the door after taking out food from the refrigerator, resulting in waste of cold energy in the box.

[0071] Alternatively, if Figure 3 As shown, the rebound assembly 150 includes an assembly body 151, an elastic member 152 and an abutment portion 153. The elastic member 152 is sleeved on the assembly body 151. One end of the abutment portion 153 is connected to the elastic member 152, and the other end is used to abut against the second end of the third connecting rod 133, and under the action of the third connecting rod 133, the elastic member 152 is compressed.

[0072] Specifically, the rebound assembly 150 includes an assembly body 151, an elastic member 152, and an abutment portion 153. The first end of the assembly body 151 is fixedly disposed on the first mounting portion 110, and the other end of the assembly body 151 is a telescopic rod 1511 that can be telescoped, and the telescopic end of the telescopic rod 1511 is connected to the first end of the abutment portion 153. The elastic member 152 is sleeved on the telescopic rod 1511 of the assembly body 151, the first end of the elastic member 152 is connected to the assembly body 151, and the second end of the elastic member 152 is connected to the abutment portion 153.

[0073] Specifically, when the opening angle of the refrigerator door is greater than the second set angle, the second end of the third connecting rod 133 will abut against the abutment portion 153, so that the telescopic rod 1511 is retracted inwardly, and the elastic member 152 is compressed inwardly. In this way, after the user takes out items from the refrigerator, the refrigerator door can be automatically closed under the action of the elastic member 152 rebounding.

[0074] Optionally, the elastic member 152 is a spring or a rubber member.

[0075] In the disclosed embodiment, the elastic member 152 is sleeved with the component body 151151, that is, one end of the elastic member 152 is connected to the abutment portion 153, so that after the door of the refrigerator is opened at an angle greater than the second set angle, it can be automatically closed due to the rebound of the elastic member 152. This avoids the situation where the user forgets to close the door after taking out food from the refrigerator, resulting in a waste of cold energy in the box.

[0076] Alternatively, if Figure 4 As shown, the hinge device 100 further includes: a damper 160, which is disposed in the first sliding groove 111 and is located on a side away from the door body rotation axis.

[0077] Specifically, when the door of the refrigerator is closed, a large impact force may be generated on the refrigerator body, causing damage to the refrigerator body or the door.

[0078] Therefore, the present application provides a damper 160 in the first sliding groove 111 of the first mounting portion 110, on a side away from the door body rotation axis. In this way, when the door body of the refrigerator is closed, the impact force on the cabinet can be reduced under the action of the damper 160, thereby reducing the risk of damage to the door body or cabinet of the refrigerator.

[0079] Alternatively, if Figure 5 As shown, the damper 160 includes a damper body 161 and a plurality of protrusions 162. The plurality of protrusions 162 are evenly arranged on the damper body 161, and the plurality of protrusions 162 are elastic.

[0080] Specifically, a plurality of elastic protrusions 162 are evenly arranged on the damper body 161, so that when the door is closed, the damper 160 can contact the first end of the first connecting rod 131 from multiple directions, dispersing the impact force of the first end into forces in multiple directions. In this way, the impact force of the door of the refrigerator on the refrigerator body is further reduced.

[0081] Optionally, the damper body 161 and the plurality of protrusions 162 are made of rubber material.

[0082] Alternatively, if Figure 6 As shown, the hinge device 100 further includes a slide slot cover 170 . The slide slot cover 170 is disposed on the upper portion of the first slide slot 111 .

[0083] Specifically, since the refrigerator is usually arranged in the kitchen, debris or dust can easily enter the first sliding groove 111. When there are debris or dust in the first sliding groove 111, the first end of the first connecting rod 131 will be affected from sliding in the first sliding groove 111.

[0084] Therefore, in the embodiment of the present disclosure, a slide slot cover 170 is disposed on the upper portion of the first slide slot 111 , thereby reducing debris or dust from falling into the first slide slot 111 and reducing the influence on the sliding of the first end of the first connecting rod 131 in the first slide slot 111 .

[0085] In some embodiments, the present disclosure provides a refrigerator such as Figure 7 The refrigerator 200 comprises a box body 210, a door body 220 and the above-mentioned hinge device (not shown in the figure). The hinge device is used to hinge the box body 210 and the door body 200.

[0086] In the implementation of the present disclosure, the cabinet 210 and the door 220 of the refrigerator 200 are hinged by the hinge device, so that the refrigerator 200 can limit the maximum opening angle of the door 220 to the first set angle, reducing the risk of the door 220 colliding with the wall of the deep and narrow space, and reducing the risk of damage to the door 220. And because the lever arm formed by the hinge device is relatively long, a wider rotation space can be formed between the cabinet 210 and the door 220 of the refrigerator 200. When the door 220 is opened, a greater distance is formed between the cabinet 210 and the door 220. Therefore, when the door 220 of the refrigerator 200 is opened, the door 220 can be separated from the deep and narrow space, reducing the risk of the door 220 interfering with the deep and narrow space or other objects when the door 220 is opened.
