[0002] Currently, most refrigerator doors on the market do not have an automatic hovering function. The locking function after the door is closed is mainly achieved by the force generated by the interference fit between the door hinge and the door closer. After the door is opened, the door hinge is separated from the door closer and is in a free state and cannot hover freely. The user experience is poor and it is inconvenient for users to take food from the refrigerator compartment.

Although this structure is simple and easy to implement, the door closer is a plastic part, and the convex and pit are interference fit during the relative rotation process.

[0049] The door body hovering function proposed in the prior art solution is mainly to add a pit design on one side and a convex design on the other side on the mating surface between the door body and the hinge, so that the door body can hover by the cooperation between the pit and the convex during the opening and closing process of the door body. Although this structure is simple and easy to implement, the door closer is a plastic part, and the convex and pit are interference fit during the relative rotation process. The multiple interference frictions during the rotation process cause great wear on the door closer, resulting in poor reliability of the door closer, which seriously affects the user experience. To this end, the present application provides a method such as Figures 1 to 9The hovering assembly shown includes: a first abutting member 1, which is arranged on a first preset structure 10; a second abutting member 2, which is arranged on a second preset structure 20, and the second preset structure 20 is rotatably arranged on the first preset structure 10; a plurality of abutting positions 21 are arranged on the second abutting member 2, and the first abutting member 1 has a first state of abutting and matching with any of the abutting positions 21, and the first abutting member 1 also has a second state of disengaging from the second abutting member 2. The first abutting member 1 is matched with different abutting positions 21, so that the second preset structure 20 can be hovered in different states, and the first abutting member 1 can switch between the first state and the second state, so that when hovering is required, the first abutting member 1 abuts with the second abutting member 2, and when hovering is not required, the first abutting member 1 switches to the second state for avoidance, effectively avoiding the problem of wear and tear in the prior art that movement can only be achieved through friction, improving the reliability of the hovering assembly, and also improving the user experience.

[0050] Specifically, the hovering assembly further includes a driving structure, which is connected to the first abutment 1, and the driving structure can switch the first abutment 1 between the second state and the first state. The driving structure is used to move the first abutment 1, thereby ensuring that the first abutment 1 can move in a controllable manner, that is, the first abutment 1 can be driven to switch to the first state to ensure the reliable hovering of the second preset structure 20, and the first abutment 1 can be driven to switch to the second state to avoid the problem of requiring a large force when the second preset structure 20 needs to move, thereby effectively improving the user experience.

[0051] The driving structure includes a reset mechanism 3, and the reset mechanism 3 is connected to the first preset structure 10 and the first abutment 1, and the reset mechanism 3 can switch the first abutment 1 from the second state to the first state. The reset mechanism 3 is used to drive the first abutment 1 to switch to the first state, thereby ensuring that when the second preset structure 20 is opened to any position, the first abutment 1 can be driven by the reset mechanism 3 to have the ability to cooperate with the corresponding abutment position 21, thereby ensuring that the abutment cooperation between the first abutment 1 and the second abutment 2 is reliable. After the second preset structure 20 reaches the set position, the first abutment 1 can be driven by the reset mechanism 3 to quickly abut with the second abutment 2, thereby ensuring that the second preset structure 20 can stay at the set position, and the second preset structure 20 can be suspended. When the user operates the second preset structure 20 to open, the second abutment 2 moves with the second preset structure 20, and the abutment position 21 on the second abutment 2 also changes. At this time, the reset mechanism 3 always controls the first abutment 1 to switch to the first state. At this time, the first abutment 1 will be squeezed by the second abutment 2 at the abutment position 21 and cannot enter the abutment position 21. Only when the user releases the second preset structure 20 can the first abutment 1 enter the abutment position 21 and realize the abutment between the first abutment 1 and the second abutment 2, thereby realizing the hovering of the second preset structure 20.

[0052] As an embodiment, the reset mechanism 3 includes an elastic member, a first end of the elastic member abuts against the first preset structure 10, and a second end of the elastic member abuts against the first abutting member 1. The elastic member accumulates elastic force to drive the first abutting member 1 to move. Figure 1 As shown, when the first abutment 1 switches from the second state to the first state, the elastic member can be squeezed and continue to exert elastic force, and when the external force on the first abutment 1 disappears, the elastic member can release the elastic force and drive the first abutment 1 to switch to the first state, thereby maintaining abutment cooperation with the second abutment 2, thereby ensuring the working reliability of the hovering assembly.

[0053] The driving structure also includes a driving mechanism, which is arranged on the first preset structure 10, and the driving mechanism can drive the first abutment 1 to switch from the first state to the second state. The first abutment 1 is driven by the driving mechanism to switch to the second state, so that the first abutment 1 and the second abutment 2 can be disengaged. At this time, the movement of the second preset structure 20 will not be affected by the cooperation between the first abutment 1 and the second abutment 2, thereby reducing the force applied by the user when moving the second preset structure 20, effectively improving the user experience, and the driving mechanism can be controlled by electrical signals, thereby improving the automation level of the hovering component and further improving the user experience.

[0054] Specifically, the driving mechanism includes a first electromagnetic component and a second electromagnetic component, the first electromagnetic component is arranged on the first preset structure 10, and the second electromagnetic component is arranged on the first abutment 1, and the first electromagnetic component and the second electromagnetic component cooperate with each other magnetically. When the first abutment 1 needs to move, the first electromagnetic component and the second electromagnetic component are both energized to generate magnetic force, and the first electromagnetic component and the second electromagnetic component can attract or repel each other, so that the first abutment 1 can switch to the second state under the action of the magnetic force, so that the first abutment 1 and the second abutment 2 are disengaged from each other, and the second preset structure 20 can move without being limited by the first abutment 1 and the second abutment 2, thereby reducing the user's need to exert greater force to operate the second preset structure 20 to move, thereby improving the user experience. At the same time, when the first abutment 1 moves under the action of magnetic force, the elastic member is squeezed or stretched to accumulate elastic force; and when the first electromagnetic member and the second electromagnetic member lose power, the elastic member can release the elastic force to drive the first abutment 1 to move, that is, the first abutment 1 can switch to the first state. During the whole process, it is only necessary to control whether the first electromagnetic member and the second electromagnetic member are powered on to achieve the control of the entire hovering assembly, which effectively reduces the control difficulty of the hovering assembly and further improves the user experience.

[0055] As another embodiment, the driving mechanism includes a second electromagnetic member and a magnetic member, wherein the magnetic member is arranged on the first preset structure 10, and the second electromagnetic member is arranged on the first abutment member 1, and the magnetic member and the second electromagnetic member cooperate with each other magnetically. When the first abutment member 1 needs to move, the second electromagnetic member is energized to generate magnetic force, and the magnetic member and the second electromagnetic member can attract or repel each other, so that the first abutment member 1 can switch to the second state under the action of the magnetic force, so that the first abutment member 1 and the second abutment member 2 are disengaged from each other, and the second preset structure 20 can move without being limited by the first abutment member 1 and the second abutment member 2, thereby reducing the user's need for greater force to operate the second preset structure 20 to move, thereby improving the user experience. At the same time, when the first abutment 1 moves under the action of magnetic force, the elastic member is squeezed or stretched to accumulate elastic force; and when the second electromagnetic member loses power, the elastic member can release the elastic force to drive the first abutment 1 to move, that is, the first abutment 1 can switch to the first state. During the whole process, it is only necessary to control whether the second electromagnetic member is energized to achieve the control of the entire hovering assembly, which effectively reduces the control difficulty of the hovering assembly and further improves the user experience.

[0056] As another embodiment, since the first abutment 1 needs to be moved and it is inconvenient to set an electromagnetic part on the first abutment 1, the driving mechanism includes a first electromagnetic part and a magnetic part. The first electromagnetic part is set on the first preset structure 10, and the magnetic part is set on the first abutment 1. The first electromagnetic part and the magnetic part cooperate magnetically. When the first abutment 1 needs to move, the first electromagnetic part is energized to generate magnetic force, and the first electromagnetic part and the magnetic part can attract or repel each other, so that the first abutment 1 can switch to the second state under the action of magnetic force, so that the first abutment 1 and the second abutment 2 are disengaged from each other, and the second preset structure 20 can move without being limited by the first abutment 1 and the second abutment 2, thereby reducing the user's need to exert greater force to move the second preset structure 20 and improving the user experience. At the same time, when the first abutment 1 moves under the action of magnetic force, the elastic member is squeezed or stretched to accumulate elastic force; and when the first electromagnetic member loses power, the elastic member can release the elastic force to drive the first abutment 1 to move, that is, the first abutment 1 can switch to the first state. During the whole process, it is only necessary to control whether the first electromagnetic member is energized to achieve the control of the entire hovering assembly, which effectively reduces the control difficulty of the hovering assembly and further improves the user experience.

[0057] The driving structure further includes a control mechanism, which is electrically connected to the first electromagnetic member and / or the second electromagnetic member. The control mechanism can be used to control the power on and off of the first electromagnetic member and / or the second electromagnetic member, thereby controlling the operation of the hovering component and improving the user experience.

[0058] Specifically, the hovering assembly further includes a first pressure detection mechanism 4, which is disposed on the first abutment 1 or the second abutment 2, and is located at the abutment fit position of the first abutment 1 and the second abutment 2, and the first pressure detection mechanism 4 is electrically connected to the control mechanism. The first pressure detection mechanism 4 can obtain the squeezing force between the first abutment 1 and the second abutment 2. When the second preset structure 20 hovers at the preset position, the first abutment 1 and the second abutment 2 abut against each other without any mutual squeezing force, that is, at this time, the first abutment 1 and the second abutment 2 are in a state of being in contact with each other but not under force. At this time, the pressure value obtained by the first pressure detection mechanism 4 is basically 0. When the user needs to close the second preset structure 20, the user will operate the second preset structure 20 by hand, and the force of the hand can be transmitted to the abutment position 21 of the second abutment 2 and the first abutment 1 through the second preset structure 20 and the second abutment 2. At this time, the detection result of the first pressure detection mechanism 4 will be greater than 0. Therefore, by judging the detection result of the first pressure detection mechanism 4, if the detection result of the first pressure detection mechanism 4 is greater than the first preset value (for example, 0), it is determined that the user needs to close the second preset structure 20. At this time, the first pressure detection mechanism 4 sends a signal to the control mechanism, and the control mechanism can control the first electromagnetic component and / or the second electromagnetic component to be energized according to this signal, and the first abutment member 1 switches to the second state to release the second preset structure 20. The user continues to apply force to the second preset structure 20 to drive the second preset structure 20 to move and realize the closure of the second preset structure 20.

[0059] Optionally, the suspension assembly further includes a second pressure detection mechanism, an operating portion is provided on the second preset structure 20, the second pressure detection mechanism is provided at the operating portion, and the second pressure detection is electrically connected to the control mechanism. When the second preset structure 20 is suspended at the preset position, the user's hand will leave the operating part. At this time, the pressure value obtained by the second pressure detection mechanism is basically 0. When the user needs to close the second preset structure 20, the user will operate the second preset structure 20 with his hand, and the force of the hand will squeeze the operating part. At this time, the detection result of the first pressure detection mechanism 4 will be greater than 0. When the user moves the second preset structure 20, the user will squeeze the operating part with his hand. At this time, the second pressure detection mechanism can obtain the squeezing force at the second operating part to determine whether the user needs to close the second preset structure 20. Therefore, by judging the detection result of the second pressure detection mechanism, if the detection result of the second pressure detection mechanism is greater than the second preset value (for example, 0), it is determined that the user needs to close the second preset structure 20. At this time, the second pressure detection mechanism sends a signal to the control mechanism, and the control mechanism can control the first electromagnetic member and / or the second electromagnetic member to be energized according to this signal, and the first abutment member 1 switches to the second state and releases the second preset structure 20. The user continues to apply force to the second preset structure 20 to drive the second preset structure 20 to move and realize the closing of the second preset structure 20.

[0060] Optionally, in order to avoid the influence of non-user operation on the working state of the hovering component, the hovering component may include a first pressure detection mechanism 4 and a second pressure detection mechanism at the same time. Only when the detection result of the first pressure detection mechanism 4 is greater than the first preset value (for example, 0) and the detection result of the second pressure detection mechanism is greater than the second preset value (for example, 0), can it be determined that the user needs to close the second preset structure 20. That is, the control mechanism needs to receive signals from the first pressure detection mechanism 4 and the second pressure detection mechanism at the same time to control the first electromagnetic member and / or the second electromagnetic member to be energized according to the signal, and the first abutment member 1 switches to the second state to release the second preset structure 20. The user continues to apply force to the second preset structure 20 to drive the second preset structure 20 to move and realize the closure of the second preset structure 20.

[0061] In order to further improve the reliability of judging whether the user needs to close the second preset structure 20, the hovering assembly also includes a temperature detection mechanism. An operating portion is provided on the second preset structure 20. The temperature detection mechanism is provided at the operating portion, and the temperature detection mechanism is electrically connected to the control mechanism. When the second preset structure 20 is suspended at the preset position, the user's hand will leave the operating part. At this time, the temperature value obtained by the temperature detection mechanism is the temperature value in the space. When the user needs to close the second preset structure 20, the user will operate the second preset structure 20 with his hand, and the temperature of the hand will be obtained by the temperature detection mechanism. At this time, the temperature detection mechanism can detect the body temperature of the human body. At this time, the temperature detection mechanism can judge whether the user needs to close the second preset structure 20 according to the temperature difference. Therefore, by judging the detection result of the temperature detection mechanism, if the detection result of the temperature detection mechanism is within the body temperature range of the human body (for example, 34°C to 40°C), it is determined that the user needs to close the second preset structure 20. At this time, the temperature detection mechanism sends a signal to the control mechanism, and the control mechanism can control the first electromagnetic component and / or the second electromagnetic component to be energized according to this signal, and the first abutment member 1 switches to the second state and releases the second preset structure 20. The user continues to apply force to the second preset structure 20 to drive the second preset structure 20 to move and realize the closure of the second preset structure 20.

[0062] Optionally, in order to avoid the influence of non-user operations (such as the ambient temperature being within the preset temperature range, the second preset structure being affected by wind force, etc.) on the working state of the hovering component, the hovering component can simultaneously include at least two of the first pressure detection mechanism 4, the second pressure detection mechanism and the temperature detection mechanism. Only when at least two of the three conditions that the detection result of the first pressure detection mechanism 4 is greater than the first preset value (such as 0), the detection result of the second pressure detection mechanism is greater than the second preset value (such as 0), and the detection result of the temperature detection mechanism is within the human body temperature range (such as 34°C to 40°C) are met, can it be determined that the user needs to close the second preset structure 20, that is, the control mechanism needs to receive signals from at least two of the first pressure detection mechanism 4, the second pressure detection mechanism, and the temperature detection mechanism at the same time, so that it can control the first electromagnetic member and / or the second electromagnetic member to be energized according to the signal, and the first abutment member 1 switches to the second state to release the second preset structure 20. The user continues to apply force to the second preset structure 20 to drive the second preset structure 20 to move and realize the closure of the second preset structure 20.

[0063] As an embodiment, all the abutment positions 21 are distributed in a ring shape with the rotation axis of the second preset structure 20 as the axis. The second preset structure 20 rotates around the rotation axis to open or close the first preset structure 10, and the second abutment member 2 can rotate with the rotation of the second preset structure 20. The first abutment member 1 is arranged on one side of the second abutment member 2. At this time, all the abutment positions 21 are distributed in a ring shape, so that the first abutment member 1 can reliably abut with any abutment position 21, thereby ensuring the working reliability of the hovering assembly.

[0064] like Figure 1 As shown, a rotating disk 22 is provided on the second abutting member 2, the central axis of the rotating disk 22 is colinear with the rotation axis of the second preset structure 20, and grooves are formed on the side walls of the rotating disk 22, each of which constitutes an abutting position 21, and the groove has a first side surface and an opposite second side surface along the rotation direction during the opening process of the second preset structure 20, and when the first abutting member 1 abuts against the groove, the first abutting member 1 abuts against the second side surface, and when the second preset structure 20 is opened, the edge of the first side surface can prevent the first abutting member 1 from sliding into the groove, thereby ensuring reliable opening of the second preset structure 20. Preferably, the rotating disk 22 is a ratchet structure.

[0065] The first end of the first abutting member 1 is hinged on the first preset structure 10 , the second end of the first abutting member 1 can abut against the abutting position 21 , and the first pressure detection mechanism 4 is arranged at the second end.

[0066] A door assembly includes the above-mentioned suspension assembly. The door assembly includes a door body and a door frame or a box body rotatably arranged on the door body, the door body forms a second preset structure 20, and the door frame or the box body forms a first preset structure 10.

[0067] A refrigerator comprises the above-mentioned suspension assembly or the above-mentioned door assembly.

[0068] A control method of the above-mentioned hovering component includes:

[0069] Determine whether the second preset structure 20 needs to be closed according to preset conditions;

[0070] If yes, the first abutting member 1 is controlled to switch to the second state, at which time the first abutting member 1 is separated from the second abutting member 2, and the second preset structure 20 can be closed freely;

[0071] If not, the first abutting member 1 is controlled to remain in the first state, at which time the first abutting member 1 maintains abutment with the second abutting member 2, and the second preset structure 20 can only continue to open but cannot be closed.

[0072] In the step of judging whether the second preset structure 20 needs to be closed according to the preset condition, the following step is also included:

[0073] Acquire a first real-time pressure value between the first abutting member 1 and the second abutting member 2 and a real-time temperature value of the operating portion of the second preset structure 20;
