[0058] like Figure 1-6As shown, the handle assembly includes a handle 1 and a driving member 2. The driving member 2 is drivingly connected to the handle 1; wherein the handle 1 is provided with a first driving portion 121, and the driving member 2 is provided with a second driving portion 221, and the first driving portion 121 can move between a driving position and a separation position relative to the second driving portion 221, and in the driving position, the first driving portion 121 cooperates with the second driving portion 221, and the second driving portion 221 can drive the first driving portion 121 to move along a preset direction, so that the driving member 2 drives the handle 1 to move from the closed position toward the hovering position; from the driving position to the separation position, the first driving portion 121 moves relative to the second driving portion 221 along a preset direction to separate from the second driving portion 221, so that the handle 1 moves from the hovering position toward the open position, wherein the hovering position is between the closed position and the open position.

[0059] The handle assembly for the refrigerator provided by the embodiment of the present disclosure is used, the handle 1 is provided with a first driving part 121, and the driving member 2 is provided with a second driving part 221. When in the driving position, the first driving part 121 cooperates with the second driving part 221, and the second driving part 221 can drive the first driving part 121 to move in a preset direction, so that the driving member 2 drives the handle 1 to move from the closed position to the hovering position, and the handle 1 is hovered by the driving action of the driving member 2, which effectively improves the automation degree of the handle assembly; the first driving part 121 can be relative to the second driving part 221 in the driving position and the separation position. The first driving part 121 moves between the positions, from the driving position to the separation position, and the first driving part 121 moves 221 relative to the second driving part along the preset direction to separate from the second driving part 221. In this way, the handle 1 can be moved from the hovering position to the open position without affecting the driving member 2, which can avoid unnecessary wear on the driving member 2 during the opening process of the power-assisted handle 1, and extend the service life of the driving member 2; at the same time, the handle 1 is in the closed position when not in use, so it can be hidden in the refrigerator door 7, which can avoid safety hazards such as bumps that may occur during the use of the refrigerator, and save shipping space.

[0060] Optionally, one of the first driving portion 121 and the second driving portion 221 is a protrusion 2211, and the other is a groove 1211. Figure 2 As shown, the groove 1211 extends along a preset direction, and the protrusion 2211 is located in the groove 1211 and can move relative to the groove 1211 along the preset direction.

[0061] The first driving portion 121 is a protrusion, and the second driving portion 221 is a groove, or the first driving portion 121 is a groove, and the second driving portion 221 is a protrusion.

[0062] The groove wall of the groove 1211 includes a first groove wall 1212 and a second groove wall 1213 which are arranged opposite to each other, and the second groove wall 1213 and the first groove wall 1212 are arranged in sequence along a preset direction. When the first driving part 121 and the second driving part 221 cooperate, that is, in the driving position, the protrusion 2211 abuts against the first groove wall of the groove 1211, and the second driving part 221 can drive the first driving part 121; when the groove 1211 moves along the preset direction relative to the protrusion 2211, the protrusion 2211 separates from the first groove wall of the groove 1211, so that the handle 1 can move freely relative to the driving member 2, and the handle 1 can move from the hovering position to the open position.

[0063] The first driving part 121 and the second driving part 221 can be respectively configured as a groove 1211 and a protrusion 2211. The configuration of the matching structure of the groove 1211 and the protrusion 2211 enables the groove 1211 and the protrusion 2211 to move relative to each other in a preset direction without affecting each other within a certain distance range, that is, along the length range of the groove 1211. This can effectively realize the movement of the handle 1 from the hovering position toward the open position.

[0064] Optionally, the groove wall of the groove 1211 further includes a third groove wall 1214 and a fourth groove wall 1215, wherein the third groove wall 1214 is connected to one end of the first groove wall 1212 and the second groove wall 1213, and the fourth groove wall 1215 is connected to the other end of the first groove wall 1212 and the second groove wall 1213. The third groove wall 1214 or the fourth groove wall 1215 is provided with an installation notch 1212 for the protrusion 2211 to be inserted into the groove 1211, and the protrusion 2211 is inserted into the groove 1211 from the installation notch 1212 to achieve the matching between the protrusion 2211 and the groove 1211.

[0065] Optionally, the distance between the installation notch 1212 and the first groove wall 1213 is greater than the distance between the installation notch 1212 and the second groove wall 1213 , so as to prevent the protrusion 2211 from escaping from the groove 1211 through the installation notch 1212 in the separation position.

[0066] Optionally, the driving member 2 includes a driving shaft 22 and a driving body 21, the driving shaft 22 is drivingly connected to the handle 1, and the second driving part 221 is arranged on the driving shaft 22; the driving body 21 is drivingly connected to the driving shaft 22, and is used to drive the driving shaft 22 to rotate, so as to drive the handle 1 to rotate, wherein the preset direction is the rotation direction of the driving shaft 22.

[0067] The driving member 2 specifically includes a driving shaft 22 and a driving body 21. The driving body 21 generates a driving force to drive the driving shaft 22 to rotate. The direction of rotation of the driving shaft 22 is a preset direction, that is, the direction in which the handle 1 reaches the open position from the closed position via the hovering position. Through the rotation of the driving shaft 22, the handle 1 can be driven to rotate in the preset direction to open the handle.

[0068] Optionally, the handle 1 includes a handle body 11 and a rotating shaft 12, the rotating shaft 12 is sleeved on the outside of the driving shaft 22, or the driving shaft 22 is sleeved on the outside of the rotating shaft 12, the first driving part 121 is arranged on the side wall of the rotating shaft 12, and the second driving part 221 is arranged on the side wall of the driving shaft 22. Figure 2 As shown, the first driving portion 121 is a groove 1211 disposed on the side wall of the rotating shaft 12 , and the second driving portion 221 is a protrusion 2211 disposed on the side wall of the driving shaft 22 .

[0069] The handle 1 specifically includes a handle body 11 and a rotating shaft 12. A first driving portion 121 is arranged on the side wall of the rotating shaft 12, and a second driving portion 221 is arranged on the side wall of the driving shaft 22. The rotating shaft 12 and the driving shaft 22 are sleeved together by the sleeve arrangement of the first driving portion 121 and the second driving portion 221, so that transmission can be performed.

[0070] Optionally, the handle assembly also includes a handle box 3 and a reset member (not shown in the figure), the handle 1 is arranged in the handle box 3 and can move relative to the handle box 3, wherein the handle 1 is located in the handle box 3 in the closed position, and the handle 1 protrudes out of the handle box 3 in the open position; the reset member is arranged between the handle 1 and the handle box 3, when the handle 1 moves toward the open position, the reset member is deformed to drive the handle 1 to reset.

[0071] The handle assembly is provided with a handle box 3, and the handle 1 is arranged in the handle box 3, which can better isolate and protect the handle assembly structure.

[0072] The rotating shaft 12 is arranged on the handle box 3, which can enable the handle 1 to move more stably between a closed position located inside the handle box 3 and an open position protruding from the handle box 3. Specifically, a hole can be opened in the side wall of the handle box 3, and the rotating shaft 12 can be inserted into the hole to realize the connection between the rotating shaft 12 and the handle body.

[0073] An elastic reset member is provided between the handle 1 and the handle box 3. When the handle 1 moves from the closed position to the open position, the reset member is deformed. After the handle 1 is opened, the handle 1 can automatically reset from the open position to the hovering position under the action of the reset member.

[0074] Optionally, the reset member is a torsion spring, which is sleeved on the rotating shaft 12 .

[0075] The handle 1 is opened and closed by rotating, and a torsion spring is used as a reset element of the handle 1 to better achieve rotational reset.

[0076] Optionally, the handle assembly further comprises a push rod assembly 4, such as Figure 7-9As shown, the top rod assembly 4 cooperates with the handle 1, and when the handle 1 is in the closed position, the distance between the handle 1 and the top rod assembly 4 is not zero, and when the handle 1 is opened to the hovering position, the handle 1 abuts against the top rod assembly 4, so that when the handle 1 moves from the hovering position toward the open position, the handle 1 drives the top rod assembly 4 to move toward the cabinet body of the refrigerator.

[0077] The handle assembly is provided with a push rod assembly 4, one end of which can extend out of the refrigerator door 7 and contact the refrigerator body. When the user pulls one end of the handle 1, the handle 1 pushes the push rod assembly 4 to move toward the cabinet body and abut against the cabinet body. The push rod assembly 4 applies a force to the refrigerator body, and the door can be opened with power through the lever transmission.

[0078] like Figure 7 As shown, when the handle 1 is in the closed position, the distance between the handle 1 and the push rod assembly 4 is not zero, and the handle 1 and the push rod assembly 4 are not in contact at this time. When moving from the closed position to the suspended position, the handle 1 and the push rod assembly 4 are not in contact, the push rod assembly 4 does not move, and the cabinet door is in a closed state. Figure 8 As shown, when the handle 1 is opened to the hovering position, the handle 1 abuts against the push rod assembly 4; when the handle 1 moves from the hovering position to the open position, the handle 1 drives the push rod assembly 4 to move toward the cabinet body. Under the drive of the handle 1, the push rod assembly 4 applies pressure to the refrigerator body, and the lever transmission assists the refrigerator door 7 to open. Thus, the handle 1 is opened and closed by a combination of driving and assisting.

[0079] Optionally, the push rod assembly 4 includes a slider 41 and a push rod 42, one end of the slider 41 cooperates with the handle 1, and the other end is connected to the push rod 42; the handle box 3 is provided with a through hole, such as Fig.16 As shown, one end of the push rod 42 extends out of the through hole, and when the handle 1 is in the closed position, the position of the push rod 42 is the initial position, and when the handle 1 is in the open position, the position of the push rod 42 is the extended position. The push rod 42 can move between the initial position and the extended position through the through hole, and from the initial position to the extended position, the push rod moves toward the cabinet.

[0080] The slider 41 and the push rod 42 of the push rod assembly 4 may be fixedly connected to form a whole, or may be connected by a simple abutment connection or other means.

[0081] Optionally, the refrigerator further includes a reset component (not shown in the figure), which is located between the top rod assembly and the handle box. When the handle 1 moves toward the open position, the reset component is deformed to drive the top rod assembly 4 to reset.

[0082] The reset component is arranged between the push rod assembly 4 and the handle box 3. When the handle 1 moves from the closed position to the suspended position, the handle 1 does not contact the push rod assembly 4, the push rod 42 is in the initial position, the cabinet door 7 is not opened, and the reset component does not deform. When the handle 1 moves from the suspended position to the open position, the push rod assembly 4 is driven to move toward the cabinet body, that is, the push rod 42 moves toward the extended position, the cabinet door 7 is opened, and the movement of the push rod assembly 4 drives the reset component to deform. After the handle 1 is opened, the push rod assembly 4 is reset to the initial position under the action of the reset component.

[0083] When the push rod 42 and the slider 41 are integrated, the refrigerator door 7 is closed, and the push rod assembly 4 can be directly reset by contacting the refrigerator body, or it can be reset with the assistance of a reset component; when the push rod 42 and the slider 41 are in an independent state, the refrigerator door 7 is closed, and the push rod 42 is reset by contacting the refrigerator body, and the slider 41 is reset driven by the reset component.

[0084] Optionally, the reset component is a compression spring.

[0085] Combination Figure 10-15 As shown, the embodiment of the present disclosure provides another handle assembly for a refrigerator.

[0086] Optionally, the driving member 2 includes a driving body 21, a driving shaft 22 and a transition shaft 23, and the second driving part 221 is arranged on the driving shaft 22; the transition shaft 23 is located between the driving body 21 and the driving shaft 22, and the driving body 21 is used to drive the transition shaft 23 to move along a preset direction, and the transition shaft 23 is used to drive the driving shaft 22 to move along a preset direction; the handle assembly also includes an elastic member 5, which is connected between the driving shaft 22 and the transition shaft 23 and can be deformed along a preset direction.

[0087] The handle 1 includes a handle body 11 and a rotating shaft 12 . The rotating shaft 12 is connected to a driving shaft 22 . The handle 1 can be rotated driven by the driving shaft 22 .

[0088] The elastic member is made of a material with a large elastic coefficient. When there is no obstruction 6 outside the handle 1, the driving body 21 can be driven normally. The driving body 21 drives the transition shaft 23 to rotate. At this time, the rotation of the transition shaft 23 can be transmitted to the driving shaft 22. The elastic member 5 basically does not deform. The rotation of the driving shaft 22 drives the rotating shaft 12 to rotate. The handle 1 moves under the action of the rotating shaft 12, so that the handle 1 moves from the closed position to the hovering position, thereby realizing the pop-up of the handle 1.

[0089] When there is an obstruction 6 outside the handle 1, the handle 1 cannot be opened normally, the driving body 21 is always in a driving state, and the driving transition shaft 23 is driven to rotate. However, since the handle 1 cannot move, the driving shaft 22 cannot rotate either. Therefore, the rotation of the transition shaft 23 cannot be transmitted to the driving shaft 22 normally. At this time, the elastic member 5 is deformed under the rotation of the transition shaft 23, which is equivalent to the driving force of the driving body 21 being converted into the deformation amount of the elastic member 5, thereby preventing the driving body 21 from idling, and avoiding damage caused by the idling of the driving body 21.

[0090] Alternatively, if Fig.11 As shown, the drive shaft 22 is provided with a third drive part 222, and the transition shaft 23 is provided with a fourth drive part 231. The fourth drive part 231 can move between a matching position with the third drive part 222 and an anti-blocking position relative to the third drive part 222 in a preset direction to be separated from the third drive part 222, wherein the elastic member 5 is deformed in the anti-blocking position.

[0091] When there is no obstruction 6 outside the handle 1, the driving body 21 can be driven normally, and the elastic member 5 basically does not deform. The driving force of the driving body 21 can be transmitted to the handle 1 through the rotation of the transition shaft 23 and the driving shaft 22, driving the handle 1 to rotate from the closed position to the suspended position; when there is an obstruction 6 outside the handle 1, the handle 1 cannot be opened normally, and the driving body 21 is always in motion. The driving force of the driving body 21 drives the deformation of the elastic member 5, thereby avoiding damage caused by idling of the driving body 21, increasing the service life of the driving body 21, and realizing the anti-blocking function of the handle assembly.

[0092] After completing the door opening action, the driving body 21 reverses, and the handle 1 is reset from the open position to the hovering position under the action of the reset member. At this time, the first driving portion 121 of the rotating shaft 12 contacts the second driving portion 221 of the driving shaft 22, and under the joint action of the reset member and the driving body 21, it is reset from the hovering position to the closed position; the elastic member 5, the driving shaft 22 and the transition shaft 23 are reversed under the action of the driving body 21 to complete the reset.

[0093] The driving body 21 may be an electric motor, a motor or other components capable of providing rotation.

[0094] Taking the driving body 21 as a motor as an example, the motor shaft is connected to the transition shaft to drive the transition shaft to rotate along a preset direction.

[0095] Optionally, one of the third driving portion 222 and the fourth driving portion 231 is a protruding portion, and the other is a notch portion, the notch portion extends along a preset direction, and the protruding portion is located in the notch portion and can move relative to the notch portion along the preset direction.

[0096] The third driving portion 222 is a protruding portion, and the fourth driving portion 231 is a notched portion, or Fig.15 As shown, the third driving portion 222 is a notch portion 222 , and the fourth driving portion 231 is a protrusion portion 231 .

[0097] The third driving part 222 cooperates with the fourth driving part 231 to realize the rotation transmission between the transition shaft 23 and the driving shaft 22 .

[0098] Optionally, the elastic member 5 is a tension spring, one end of which is connected to the transition shaft 23 , and the other end of which is circumferentially connected to the drive shaft 22 .

[0099] The elastic member 5 is made of a tension spring material with a large elastic coefficient, which can effectively prevent the driving body 21 from idling.

[0100] The groove wall of the notch portion 2221 includes a fifth groove wall 2222 and a sixth groove wall 2223, which are arranged opposite to each other and arranged in sequence along a preset direction. When the handle 1 is not blocked and can be opened normally, that is, in the non-blocking position, the fifth side wall 2222 abuts against the protruding portion 2311, or the gap between the two is small, the elastic member is almost not deformed, and the driving force of the driving body 21 is almost entirely used to drive the transition shaft to rotate.

[0101] When the handle is blocked and cannot be opened normally, that is, the anti-blocking position, the driving force of the driving body drives the transition shaft to rotate. Since the driving shaft cannot rotate, the driving force of the transition shaft is mainly used to drive the elastic part to deform. The driving force of the transition shaft cannot be 100% converted into the deformation of the elastic part. Therefore, the transition shaft will be displaced a small amount relative to the driving shaft, and the protrusion moves a small amount toward the sixth side wall.

[0102] Optionally, the handle assembly further includes an elastic member 5, which is connected between the driving member 2 and the handle 1 and can be deformed along a preset direction.

[0103] The handle 1 includes a handle body 11 and a rotating shaft 12 , the driving member 2 includes a driving body 21 and a driving shaft 22 , one end of the elastic member 5 is connected to the driving shaft 22 , and the other end is connected to the rotating shaft 12 along the circumferential direction.

[0104] When there is no obstruction 6 outside the handle 1, the driving body 21 can normally drive the driving shaft 22 to rotate, and transmit the rotation of the driving shaft 22 to the rotating shaft 12. The handle 1 rotates under the action of the rotating shaft 12, and the elastic member 5 basically does not deform; when there is an obstruction 6 outside the handle 1, the handle 1 cannot be opened normally, the rotating shaft 12 cannot rotate, the driving body 21 is always in motion, and the driving body 21 drives the driving shaft 22 to rotate. At this time, the elastic member 5 is stretched under the rotation of the driving shaft 22, thereby avoiding damage caused by idling of the driving body 21 and improving the service life of the driving body 21.

[0108] The sensor may be a pressure sensor, which is disposed on the handle 1 and is used to detect the pressure information on the handle 1. When the user opens the door, by pressing one end of the handle 1, the sensor detects a certain pressure value and transmits a signal to the controller, which controls the driving member to drive the handle 1 to move out of the cabinet door 7 to a hovering position, and the user can complete the opening movement of the cabinet door 7 by pulling the handle 1 to the open position; the sensor detects that the pressure disappears and transmits a signal to the controller, which controls the driving member to drive the handle 1 to move and reset to the closed position, and the handle 1 can be hidden in the cabinet door 7.

[0109] The sensor can also be a human proximity sensor, which is arranged on the handle assembly or the cabinet door 7 and is used to detect the user's body and the distance between the user and the refrigerator. When the sensor detects that the user is approaching, it transmits a signal to the controller, and the controller controls the driving member to drive the handle 1 to move out of the cabinet door 7 to a hovering position. The user can complete the opening movement of the cabinet door 7 by pulling the handle 1 to the open position; when the sensor detects that the user is away, it transmits a signal to the controller, and the controller controls the driving member 2 to drive the handle 1 to move and reset to the closed position, and the handle 1 can be hidden in the cabinet door 7.
