[0028] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0029] In combination Figures 1 to 12 As shown in the drawings, the handle assembly is used for a refrigeration device, the refrigeration device comprises a cabinet and a door body, the handle assembly comprises a handle 10 and a lock nose 30, the handle 10 comprises a handle body 11, the handle body 11 is adapted to be rotatably arranged on the door body 60, the handle body 11 is provided with a door opening protrusion 111, the handle body 11 defines a rotation space 13, and the handle body 11 can rotate relative to the door body 60 between an open door position for opening the door body 60 and a closed door position for closing the door body 60; the lock nose 30 is adapted to be arranged on the cabinet 50; wherein when the handle body 11 moves from the closed door position to the open door position, the door opening protrusion 111 can be in contact with the lock nose 30, and the lock nose 30 applies a force to the door opening protrusion 111 away from the cabinet 50 to assist in opening the door body 60; when the handle body 11 moves from the open door position to the closed door position, the wall surface of the rotation space 13 can be in contact with the lock nose 30, and the lock nose 30 applies a force to the handle body 11 to move toward the cabinet 50 to lock the door body 60.

[0030] In the embodiments of the present disclosure, the handle assembly is used to open or close the door body 60, and the handle body 11 is used to be rotatably connected with the door body 60, so that the handle 10 can be rotated for the user to operate and control. When the handle body 11 rotates to open the door, the door opening protrusion 111 of the handle 10 can apply a force to the lock nose 30, and since the lock nose 30 is fixed on the cabinet 50, the lock nose 30 will apply a reverse force to the handle 10, thereby making the door opening protrusion 111 move away from the cabinet 50, and the handle 10 drives the door body 60 to move away from the cabinet 50, thereby greatly reducing the force required by the user to open the door, improving the convenience of opening the door, and achieving power-assisted opening. When the door needs to be closed, the handle 10 is reversely rotated, and the rotation space 13 of the handle body 11 can be in contact with the lock nose 30, and since the lock nose 30 is fixed on the cabinet 50, the lock nose 30 will apply a force to the handle 10 to move toward the cabinet 50, so that the door body 60 is more closely attached to the cabinet 50, which can ensure that the door is closed in place, and when a sealing strip is arranged between the cabinet 50 and the door body 60, the sealing strip can also be compressed, thereby ensuring the sealing effect of the cabinet 50 and the door body 50.

[0031] In addition, the handle assembly in the present application has the effects of power-assisted opening and power-assisted closing, and the door opening protrusion 111 and the rotation space 13 are integrated on the handle 10, without the need to arrange additional power-assisted parts or locking mechanisms, thereby reducing the cost and improving the convenience of use.

[0032] Optionally, as Figure 4 , Figure 6 and Figure 7As shown, the door opening protrusion 111 includes a first wall surface 112, when the handle body 11 is in the door closing position, the first wall surface 112 is located on the side of the door opening protrusion 111 facing the lock nose 30, and the first wall surface 112 includes a power assisting starting position 1121, when the handle body 11 moves from the door closing position to the door opening position, the lock nose 30 starts to contact the first wall surface 112 from the power assisting starting position 1121, and exerts a force on the door opening protrusion 111 away from the cabinet 50; wherein, when the handle body 11 is in the door closing position, the distance between the power assisting starting position 1121 and the cabinet 50 is smaller than the distance between other positions of the first wall surface 112 and the cabinet 50.

[0033] In the embodiment of the present disclosure, when the handle body 11 is in the door closing position, the distance between the power assisting starting position 1121 of the door opening protrusion 111 and the cabinet 50 is the smallest, so that when the door opening protrusion 111 moves with the handle 10, the power assisting starting position 1121 of the door opening protrusion 111 first contacts the lock nose 30, and can stably transmit the force, ensuring the stability of the door opening. The other positions of the first wall surface 112 provide a buffer space between the handle 10 and the lock nose 30, ensuring the smoothness of the movement, and can also improve the flexibility of the movement of the handle 10.

[0034] Optionally, the first wall surface 112 further includes a power assisting surface 1122, which is connected to one side of the power assisting starting position 1121, and when the handle body 11 moves from the door closing position to the door opening position, the lock nose 30 contacts the power assisting starting position 1121, and then the lock nose 30 moves along the power assisting surface 1122 beyond the power assisting starting position 1121.

[0035] In the embodiment of the present disclosure, the power assisting surface 1122 is connected to the power assisting starting position 1121, and after the lock nose 30 moves beyond the power assisting starting position 1121 along the power assisting surface 1122, the power assisting effect of the lock nose 30 on the door opening protrusion 111 continues to exist throughout the opening process, avoiding the situation that there is power assisting only in the initial stage and no power assisting thereafter, and further reducing the opening operation force.

[0036] Optionally, when the handle body 11 is in the door closing position, the power assisting surface 1122 is inclined away from the cabinet 50.

[0037] In the embodiment of the present disclosure, the power assisting surface 1122 is inclined away from the cabinet 50, so that the lock nose 30 can move along the power assisting surface 1122, and the inclination of the power assisting surface 1122 facilitates the rotation of the handle 10, avoids the interference between the door opening protrusion 111 and the lock nose 30, and improves the smoothness of the rotation of the handle 10.

[0038] Optionally, when the handle body moves from the door closing position to the door opening position, the movement distance of the door body is 5mm to 10mm.

[0039] In the embodiments of the present disclosure, when the handle body moves from the door closing position to the door opening position, the movement distance of the door body is 5mm to 10mm. The movement distance is limited to 5mm to 10mm, which can ensure sufficient contact length to achieve continuous assistance, and avoid the problem of excessive volume of the handle body 11 caused by the too long assistance surface 112.

[0040] Optionally, when the handle body moves from the door closing position to the door opening position, the movement distance of the door body is 7mm to 8mm.

[0041] In the embodiments of the present disclosure, when the handle body moves from the door closing position to the door opening position, the movement distance of the door body is 7mm to 8mm, which can further ensure the interference fit distance between the handle body 11 and the lock nose 30, and will not increase the volume of the handle body 11.

[0042] Optionally, as shown in Figure 8 and Figure 9 The handle assembly further includes a first limiting piece 23, and the first wall surface 112 further includes a limiting protrusion 1123. The limiting protrusion 1123 is located on the side of the assistance starting position 1121 away from the assistance surface 1122. The first limiting piece 23 is movably located on the side of the limiting protrusion 1123. When the handle body 11 moves to the door opening position, the first limiting piece 23 abuts against the limiting protrusion 1123 to limit the handle body 11 from continuing to rotate in the door opening direction.

[0043] In the embodiments of the present disclosure, the first limiting piece 23 and the limiting protrusion 1123 can avoid the handle 10 from rotating out of position and avoid the problem of the loose handle 10 affecting other components or other users.

[0044] Optionally, as shown in Figure 4 The handle body 11 is provided with a rotating part 12. The rotating part 12 is provided with a rotating hole 121. The handle assembly includes a rotating shaft 21. The rotating shaft 21 is arranged on the door body 60. The rotating hole 121 is rotatably arranged on the outer side of the rotating shaft 21. The door opening protrusion 111 is connected to one side of the rotating part 12. The rotating part 12 includes a second wall surface 122. When the handle body is located at the door closing position, the second wall surface 122 is located on the side of the rotating part 12 facing the lock nose 30. The connection between the first wall surface 112 and the second wall surface 122 forms a first rotating groove 1124. When the first limiting piece 23 abuts against the limiting protrusion 1123, the first limiting piece 23 is located in the first rotating groove 1124.

[0045] In the embodiments of the present disclosure, the rotating hole 121 is located outside the rotating shaft 21, so that the rotating connection between the handle body 11 and the door body 60 can be achieved, so as to facilitate the movement of the handle 10 between the open door position and the closed door position. The open door protrusion 111 is connected with the rotating part 12, so that when the rotating part 12 moves around the rotating shaft 21, the open door protrusion 111 can also rotate with the rotating part 12. The first wall surface 112 forms the power assisting surface 1122 and the power assisting starting position 1121 to cooperate with the lock nose 30 to assist the opening of the door. When the first limiting part 23 is limited by the limiting protrusion 1123, the first limiting part 23 is located in the first rotating groove 1124, so that the rotating column can be stably arranged in the first rotating groove 1124 and can cooperate with the limiting protrusion 1123.

[0046] Optionally, as shown in Figure 4 , one end of the second wall surface 122 away from the first wall surface 112 is provided with a second rotating groove 123. When the handle body 11 is located at the closed door position, the first limiting part 23 is located in the second rotating groove 123. When the handle body 11 is located at the open door position, the first limiting part 23 is located in the first rotating groove 1124. When the handle body 11 moves from the closed door position to the open door position, the first limiting part 23 moves from the second rotating groove 123 along the second wall surface 122 to the first rotating groove 1124.

[0047] In one specific embodiment, when the handle body 11 is located at the closed door position, the first wall surface 112 partially protrudes towards the direction of the cabinet 50 to form the power assisting starting position 1121. The limiting protrusion 1123 and the power assisting surface 1122 are respectively located on both sides of the power assisting starting position 1121. The connecting part of the limiting protrusion 1123 and the second wall surface 122 forms the first rotating groove 1124.

[0048] Optionally, as shown in Figure 4 , Figure 10 and Figure 11 , the rotating space 13 includes a third wall surface 131. When the handle body 11 is located at the closed door position, the third wall surface 131 is located on the side of the lock nose 30 away from the door body 60. The third wall surface 131 includes a closed door urgent position 132 and a closed door end position 133. When the handle body 11 moves from the open door position to the closed door position, the lock nose 30 starts to contact the third wall surface 131 from the closed door urgent position 132 and applies a force to the handle body 11 towards the cabinet 50. When the handle body 11 is located at the closed door position, the lock nose 30 is located at the closed door end position 133. When the handle body 11 is located at the closed door position, the distance between the closed door urgent position 132 and the door body 60 is less than the distance between the closed door end position 133 and the door body 60.

[0049] In the embodiments of the present disclosure, the third wall surface 131 is provided with a door closing urgent position 132 and a door closing end position 133, and the handle body 11 is located at the door closing position, and the door closing urgent position 132 is closer to the door body 60. When the handle 10 rotates from the door opening position to the door closing position, the lock nose 30 first contacts the door closing urgent position 132, at this time, the force applied by the lock nose 30 to the cabinet 50 has a high initial strength, which can quickly pull the door body 60 to adhere to the cabinet 50. With the continuous rotation of the handle 10, the lock nose 30 moves to the door closing end position 133, and because the door closing end position 133 is farther away from the door body 60, the direction and size of the force can adapt to the position change of the door body 60 during the closing process, forming a gradual locking process, avoiding the problem that the door body 60 rebounds or does not adhere tightly due to the sudden change of force during traditional closing, and significantly improving the locking firmness of the door body 60 and the cabinet 50.

[0050] Optionally, a guide surface 134 is formed between the door closing urgent position 132 and the door closing end position 133, and the lock nose 30 moves along the guide surface 134 towards the door closing end position 133 after contacting the door closing urgent position 132.

[0051] Optionally, the guide surface 134 is an arc surface, so that the movement of the door body 60 during closing is more gentle, avoiding the problem that the door body 60 rebounds or does not adhere tightly due to the sudden change of force during closing.

[0052] Optionally, when the handle body rotates from the door closing position in a first rotation direction (away from the cabinet) by a first set angle, the lock nose contacts the force assisting starting position; and when the handle body rotates from the door closing position in a second rotation direction (towards the cabinet) by a second set angle, the lock nose contacts the door closing urgent position 132.

[0053] Optionally, the first set angle is 20° to 50°.

[0054] Optionally, the first set angle is 20°, 30°, 40°, 50°, etc.

[0055] Optionally, the second set angle is less than or equal to the first set angle.

[0056] Optionally, the handle assembly comprises a second limiting piece 24, the second limiting piece 24 is movably located in the rotation space 13, and when the handle body 11 moves to the door closing position, the second limiting piece 24 can abut against the inner wall of the rotation space 13 to limit the handle body 11 from continuing to move towards the door closing direction.
