DETAILED DESCRIPTION

[0050] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0051] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the embodiments of the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0052] In order to better understand the hinge 3 provided in the present application, the refrigeration device 100 is first described.

[0053] The present application provides a refrigeration device 100. Figure 1 and Figure 3 The refrigeration device 100 includes a cabinet 1, a door 2 and a hinge 3. The hinge 3 is connected between the cabinet 1 and the door 2.

[0054] For example, in one embodiment, please refer to Figure 3 The box body 1 is formed with a storage cavity 1a and a taking port 1b connected to the storage cavity 1a. The door body 2 is connected to the box body 1 through a hinge 3, and is used to selectively open or close the taking port 1b. When it is necessary to take out or place items in the storage cavity 1a, the door body 2 can be pulled or pushed. In this way, under the action of the hinge 3, the door body 2 can rotate relative to the box body 1 to open or close the taking port 1b.

[0055] Another aspect of the present application embodiment provides a hinge 3, see Figures 1 to 13 The hinge 3 includes a fixed seat 31, a movable seat 32 and an adjusting device 33. An adjusting hole 31a is formed in the fixed seat 31. The movable seat 32 is rotatably connected to the fixed seat 31.

[0056] One end of the adjusting device 33 is connected to the movable seat 32, and the other end of the adjusting device 33 can be movably located in the adjusting hole 31a. The connection point of the adjusting device 33 has an open position a and a closed position b in the rotation direction of the movable seat 32. The adjusting device 33 has a protrusion 33a. When the connection point of the adjusting device 33 is in the open position a and / or the closed position b, the protrusion 33a contacts the adjusting hole 31a.

[0057] Exemplarily, the fixed seat 31 can be disposed on the box body 1 , and the movable seat 32 can be disposed on the door body 2 .

[0058] Exemplarily, when the connection point of the adjusting device 33 is in the open position a, the door body 2 can be opened accordingly, and when the connection point of the adjusting device 33 is in the closed position b, the door body 2 can be closed accordingly.

[0059] Exemplarily, when the door body 2 is opened to form a first angle with the box body 1, the connection point of the adjustment device 33 is in the open position a, that is, when the door body 2 is opened to form a first angle with the box body 1, the protrusion 33a contacts the adjustment hole 31a. When the door body 2 is closed to form a second angle with the box body 1, the connection point of the adjustment device 33 is in the closed position b, that is, when the door body 2 is closed to form a second angle with the box body 1, the protrusion 33a contacts the adjustment hole 31a.

[0060] It should be noted that the first angle and the second angle may be the projection angles of the door body 2 and the box body 1 along the width direction, for example Figure 3 , at this time, the angle between the door body 2 and the box body 1 is the first angle; for example Figure 1 At this time, the angle between the door body 2 and the box body 1 is the second angle.

[0061] The hinge 3 provided by the embodiment of the present application is connected by a movable seat 32 and a fixed seat 31, so that the door body 2 connected with the movable seat 32 can rotate relative to the box body 1 connected with the fixed seat 31 to open or close the door body 2. By connecting one end of the adjusting device 33 to the movable seat 32, the other end of the adjusting device 33 can be movably located in the adjusting hole 31a, so that when the movable seat 32 rotates, it will drive the adjusting device 33 to move. For example, when the connection point of the adjusting device 33 moves to the open position a and / or the closed position b, at this time, the other end of the adjusting device 33 will contact the adjusting hole 31a to increase the friction between the adjusting device 33 and the adjusting hole 31a, and then increase the damping of the rotation of the movable seat 32, so that the rotation speed of the movable seat 32 decreases. In this way, on the one hand, the shaking of the movable seat 32 can be reduced, that is, the shaking of the door body 2 can be reduced, and the stability is good; on the other hand, the impact on the box body 1 caused by the door body 2 rotating too fast can be reduced.

[0062] For example, in one embodiment, the shape of the box body 1 is not limited, for example, it can be a cuboid or a cube, etc. The shape of the door body 2 is also not limited, for example, it can be a rectangle or a square, etc.

[0063] Illustratively, in one embodiment, the refrigeration device 100 may be a refrigerator or a freezer.

[0064] In one embodiment, please refer to Figure 2 as well as Figures 4 to 13 The hinge 3 includes a rotating shaft 34, a third rotating hole is formed on the fixed seat 31, and a fourth rotating hole is formed on the movable seat 32, and the rotating shaft 34 is inserted into the third rotating hole and the fourth rotating hole. In this way, the movable seat 32 is connected to the fixed seat 31 through the rotating shaft 34. On the one hand, it is convenient to connect the fixed seat 31 with the movable seat 32 without complicated fixing or welding operations, saving a lot of time and manpower; on the other hand, the connection through the rotating shaft 34 allows a certain relative rotation between the movable seat 32 and the fixed seat 31, that is, the door body 2 and the box body 1, so that it can be adjusted as needed to achieve a suitable opening angle of the door body 2, and the design flexibility is strong; on the other hand, the rotating shaft 34 has good sealing performance, which can effectively prevent the cold air from leaking from the gap between the box body 1 and the door body 2, and maintain the temperature and humidity of the storage cavity 1a; on the other hand, the connection through the rotating shaft 34 has a longer service life and a lower failure rate.

[0065] In one embodiment, please refer to Figure 4 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 and Fig.12, the number of protrusions 33a is two, and the two protrusions 33a are arranged in the up-down direction. When the connection point of the adjusting device 33 is in the open position a, one of the two protrusions 33a contacts the adjusting hole 31a. When the connection point of the adjusting device 33 is in the closed position b, the other of the two protrusions 33a contacts the adjusting hole 31a. Exemplarily, the two protrusions 33a are respectively a first protrusion 33a1 and a second protrusion 33a2. When the connection point of the adjusting device 33 is in the open position a, the first protrusion 33a1 contacts the inner wall of the adjusting hole 31a. That is to say, when the door body 2 is opened to the point where the connection point of the adjusting device 33 is in the open position a, the first protrusion 33a1 contacts the inner wall of the adjusting hole 31a to increase the friction between the first protrusion 33a1 and the adjusting hole 31a, thereby increasing the damping of the rotation of the movable seat 32, so that the rotation speed of the movable seat 32 decreases to reduce the friction between the first protrusion 33a1 and the adjusting hole 31a. The movable seat 32 has little shaking and good stability; when the connection point of the adjusting device 33 is in the closed position b, the second protrusion 33a2 abuts against the inner wall of the adjusting hole 31a, that is, when the door body 2 is closed to the connection point of the adjusting device 33 is in the closed position b, the second protrusion 33a2 contacts the inner wall of the adjusting hole 31a to increase the friction between the second protrusion 33a2 and the adjusting hole 31a, so that the door body 2 can slowly descend until the door body 2 closes the object taking port 1b. In this way, excessive impact force of the door body 2 and excessive closing sound can be avoided.

[0066] In one embodiment, the two protrusions 33a are arranged at intervals in the vertical direction. In this way, when the door body 2 is closed or opened to a position where the adjustment device 33 is located between the open position a and the closed position b, the portion of the adjustment device 33 located between the first protrusion 33a1 and the second protrusion 33a2 can be movably located in the adjustment hole 31a. At this time, the friction between the adjustment device 33 and the adjustment hole 31a is small, so that the resistance of the door body 2 is also small, and the door body 2 can be quickly opened to the first angle or closed to the second angle to dynamically adjust the friction between the adjustment device 33 and the adjustment hole 31a.

[0067] In one embodiment, please refer to Figure 10 to Figure 11 The two protrusions 33a are connected in the up-down direction. In this way, the connection strength between the first protrusion 33a1 and the second protrusion 33a2 is increased to increase the stability when opening and closing the door.

[0068] In one embodiment, please refer to Figure 2 as well as Figures 4 to 13The adjusting device 33 includes a supporting guide rod 331 and an elastic member 332. One end of the supporting guide rod 331 is rotatably connected to the movable seat 32, and the supporting guide rod 331 has a protrusion 33a. The elastic member 332 is sleeved on the supporting guide rod 331 and abuts against the adjusting hole 31a. When the connection point of the adjusting device 33 is in the closed position b, the elastic member 332 is compressed. When the connection point of the adjusting device 33 is in the open position a, the elastic member 332 recovers its deformation.

[0069] As an example, taking a freezer as an example, when the door body 2 is pulled downward to close the access port 1b, as the door body 2 is closed, the door body 2 begins to rotate around the rotating shaft 34 to drive the support guide rod 331 to move, and the elastic member 332 is compressed under the movement of the support guide rod 331, which can play a certain impact buffering role in closing the door; the door body 2 continues to rotate, and at this time the gravity of the door body 2 will be greater than the elastic force provided by the elastic member 332, so that the downward pressure of the door body 2 is accelerated, and when the connection point of the adjustment device 33 moves to the closed position b, the second protrusion 33a2 on the support guide rod 331 will contact the inner wall of the adjustment hole 31a, and at this time, the door body 2 will be affected by the elastic member 332. The elastic force and the friction between the support guide rod 331 and the adjustment hole 31a work together to prevent the door body 2 from moving downward, slow down the rotation speed of the door body 2, and finally make the door body 2 slowly drop until the door body 2 closes the object taking port 1b. In this way, on the one hand, during the door closing process, the elastic member 332 and the support guide rod 331 and the adjustment hole 31a can provide a larger supporting force to avoid the situation where the impact force of closing the door causes damage to the door body 2 and the box body 1, thereby extending the service life of the box body 1, the door body 2 and the hinge 3; on the other hand, providing a larger supporting force during the door closing process makes the door body 2 drop slowly, which can reduce the closing sound and provide a good user experience.

[0070] When the door body 2 is pulled upward to open the picking port 1b, as the door body 2 opens, the door body 2 begins to rotate around the rotating shaft 34. At this time, the elastic member 332 will restore its deformation to push the support guide rod 331 to move, and then push the door body 2 to rotate, thereby accelerating the opening of the door body 2; when the connection point of the adjusting device 33 moves to the opening position a, the first protrusion 33a1 on the support guide rod 331 will contact the inner wall of the adjusting hole 31a, so that the friction between the support guide rod 331 and the adjusting hole 31a increases, so as to begin to prevent the door body 2 from opening, and the speed of opening the door body 2 begins to decrease. In this way, the shaking of the door body 2 can be reduced.

[0071] Exemplarily, in one embodiment, the elastic member 332 may be a spring. On the one hand, the spring can store elastic potential energy through compression or tension deformation, and release energy when needed, thereby completing the functions of door closing shock reduction and door opening assistance. On the other hand, the spring has good load stability and can maintain a constant load value for a long time.

[0072] In one embodiment, please refer to Figure 4 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 and Fig.12 , the height of the upper protrusion of the two protrusions increases upward, and the height of the lower protrusion of the two protrusions increases downward. Exemplarily, the height of the first protrusion 33a1 increases downward, and the height of the second protrusion 33a2 increases upward. Exemplarily, the first protrusion 33a1 and the second protrusion 33a2 can both be arranged on a side surface of the support guide rod 331 away from the movable seat 32. Taking the freezer as an example, when the door body 2 is pulled upward to open the access port 1b, as the door body 2 opens, the door body 2 begins to rotate around the rotating shaft 34, so as to drive the supporting guide rod 331 to start moving upward; when the connection point of the adjusting device 33 moves to the opening position a, the inner wall of the adjusting hole 31a will first contact the part with the smaller height of the first protrusion 33a1. At this time, the gap between the first protrusion 33a1 and the inner wall of the adjusting hole 31a is smaller, and the friction force is also smaller. When the door body 2 continues to be opened, due to the downward increase in the height of the first protrusion 33a1, the gap between the inner wall of the adjusting hole 31a and the second protrusion 33a2 becomes smaller than before, and the friction force becomes larger than before. The rotation speed of the door body 2 begins to decrease until the inner wall of the adjusting hole 31a contacts and abuts the part with the largest height of the second protrusion 33a2, thus completing the operation of opening the door body 2. In this way, by increasing the height of the first protrusion 33a1 downward, the friction between the first protrusion 33a1 and the adjustment hole 31a can be dynamically adjusted, which not only improves the smoothness of opening the door body 2 but also reduces the shaking of the door body 2, thereby providing good stability.

[0073] When the door body 2 is pulled downward to close the access opening 1b, as the door body 2 is closed, the door body 2 begins to rotate around the rotating shaft 34 to drive the support guide rod 331 to start moving downward. When the connection point of the adjustment device 33 moves to the closed position b, the inner wall of the adjustment hole 31a will first contact the part with the smaller height of the second protrusion 33a2. At this time, the gap between the second protrusion 33a2 and the inner wall of the adjustment hole 31a is smaller, and the friction force is also smaller; when the door body 2 continues to rotate, the height of the second protrusion 33a2 increases upward, so that the gap between the inner wall of the adjustment hole 31a and the second protrusion 33a2 becomes smaller than before, and the friction force becomes larger than before. The rotation speed of the door body 2 starts to decrease until the door body 2 completely closes the access opening 1b. In this way, by increasing the height of the second protrusion 33a2 upward, the closing of the door body 2 can be buffered to reduce the impact force and closing sound of the door body 2.

[0074] In one embodiment, the shape of the protrusion 33a may be wedge-shaped, for example, the first protrusion 33a1 and the second protrusion 33a2 may both be wedge-shaped.

[0075] In one embodiment, please refer to Figures 10 to 13 , the side of the protrusion 33a away from the adjusting device 33 is set as an arc. Exemplarily, the side of the protrusion 33a away from the supporting guide rod 331 can be set as an arc, so that the first protrusion 33a1 and the second protrusion 33a2 are narrow in the middle and wide at both ends along the up-down direction.

[0076] In one embodiment, the protrusion 33a is formed by punching one side of the adjusting device 33. Exemplarily, the protrusion 33a can be formed by punching one side of the supporting guide rod 331.

[0077] In one embodiment, the height of the protrusion 33a is between 0.1 mm and 3.5 mm. For example, the height of the protrusion 33a can be 0.1 mm, 0.5 mm, 1 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm or 3.5 mm, etc. In this way, by setting the protrusion 33a of a suitable height, not only the shaking of the door body 2 and the impact force of closing the door can be reduced, but also the situation that the protrusion 33a is too high and the door cannot be closed or opened can be avoided.

[0078] It should be noted that the height of the protrusion 33a mentioned here refers to the dimension of the protrusion 33a along the width direction.

[0079] In one embodiment, please refer to Fig.12 and Fig.13 , two protrusions 33a adjacent in the up-down direction form a protrusion group, the number of the protrusion groups is multiple, and the multiple protrusion groups are arranged along the circumference of the outer circumferential surface of the adjustment device 33. Exemplarily, the first protrusion 33a1 and the second protrusion 33a2 can be multiple, and one first protrusion 33a1 and one second protrusion 33a2 adjacent in the up-down direction form a protrusion group, and multiple protrusion groups are arranged at intervals along the circumferential direction of the outer circumferential surface of the support guide rod 331 to further improve the friction between the protrusion 33a and the adjustment hole 31a.

[0080] In one embodiment, please refer to Figure 2 as well as Figures 4 to 13 The hinge 3 includes a support shaft 35, a support guide rod 331 is formed with a first rotation hole, and a movable seat 32 is formed with a second rotation hole, and the support shaft 35 is inserted into the first rotation hole and the second rotation hole. In this way, the support guide rod 331 is connected to the movable seat 32 through the support shaft 35. On the one hand, the support guide rod 331 and the movable seat 32 can be conveniently connected together without complicated fixing or welding operations, saving a lot of time and manpower; on the other hand, the connection through the support shaft 35 has a longer service life and a lower failure rate.

[0081] In one embodiment, please refer to Figure 2 as well as Figures 4 to 13 The support guide rod 331 includes a support portion 3311 and a connection portion 3312, wherein the connection portion 3312 is connected to the support portion 3311, and a first rotation hole is formed in the connection portion 3312. Exemplarily, the shape of the support portion 3311 is not limited, for example, it can be a long strip, and the cross section of the support portion 3311 in the vertical direction can be circular or square. The connection portion 3312 can be connected to the end of the support portion 3311 away from the protrusion 33a, so that the support guide rod 331 is roughly "T"-shaped, and the connection portion 3312 has a first rotation hole that runs through the width direction, and the support shaft 35 is inserted into the first rotation hole and the second rotation hole of the movable seat 32.
