[0045] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] With the continuous improvement of living standards, refrigerators and freezers have become essential household appliances for most families, and people have increasingly demanding requirements for their use. Refrigeration equipment such as refrigerators and freezers has a door that separates the interior of the refrigeration unit from the outside world through a magnetic strip inside the sealing strip that engages with a metal plate outside the enclosure.

[0047] At present, some types of refrigerators have relatively large door areas and are relatively heavy. Moreover, since the door is in a closed state for a long time, the door seal magnetic strip and the center beam will generate adsorption force, and the force required to open the door for the first time is relatively large. In addition, the air pressure inside the refrigerator body will be lower than the external air pressure during the opening and closing process of the refrigerator door. When opening the door, it is necessary to overcome the pressure difference between the inside and outside of the refrigerator and the magnetic force of the door seal, which is quite strenuous.

[0048] refer to Figure 1 According to one aspect of the present application, a moving device is provided, including a mounting base 10 and a rotating assembly 20, one end of the mounting base 10 is connected to the box body 30, and is provided with a first push member 11, and is provided with a slide groove 12 extending along the first direction 100, and the slide groove 12 has a locking position 121; the rotating assembly 20 includes a second push member 21 and a driving rod 22, the second push member 21 is arranged on the driving rod 22, and the driving rod 22 is rotatably assembled in the slide groove 12, the door body 40 is connected to the driving rod 22, and the driving rod 22 drives the second push member 21 to rotate. At the locking position 121, the second push member 21 and the first push member 11 are subjected to force contact to generate a first push force away from the box body 30, so that the driving rod 22 slides to the locking position 121. This can conveniently achieve the purpose of spacing the box body 30 a certain distance from the door body 40 , avoiding interference caused by the sealing structure between the door body 40 and the box body 30 , and reducing the force required to rotate and open the door body 40 .

[0049] like Figure 1-Figure 5 As shown, the mechanism for the translation of the experimental refrigerator door 40 is a cam mechanism, which uses the cam radius difference to achieve the translation of the door 40 relative to the box body 30. This cam mechanism is driven by a motor to overcome the negative pressure and the suction of the magnetic strip. After rotating half a circle, the hinge of the refrigerator itself rotates to realize the rotation of the door 40.

[0050] refer to Figure 1As shown, under the action of the first thrust, the door body 40 can first be moved away from the box body 30 along the first direction 100, so that the box body 30 can be changed from a sealed negative pressure state to a leaking state, so that the pressure outside the door body 40 is the same as the pressure inside the box body 30, and thus the door body 40 can be opened without consuming much effort when controlling the rotation of the door body 40.

[0051] refer to Figure 2 As shown, according to one embodiment of the present application, the slide groove 12 has an unlocking position 122. In the first direction 100, the unlocking position 122 is close to the box body 30, and the locking position is away from the box body 30. In the unlocking position 122, the second push member 21 is forced to abut against the first push member to generate a second push force away from the door body 40, so that the driving rod 22 can slide away from the locking position to the unlocking position 122 through the second push force.

[0052] The second resisting force causes the door body 40 to slide along the slide groove 12 toward the side of the box body 30, thereby reducing the spacing distance between the door body 40 and the box body 30 in the first direction 100, so that the seal between the door body 40 and the box body 30 can be compressed and deformed, and the door body 40 and the box body 30 are in a closed state.

[0053] refer to Figure 3-Figure 4 As shown, according to an embodiment of the present application, the first push member 11 includes a first push portion 111, a second push portion 112 and a guide slide 113, the guide slide 113 is arranged between the first push portion 111 and the second push portion 112, the first push portion 111 is close to the door body 40, and the second push portion 112 is away from the door body 40;

[0054] In which, in the locked position, there is a first pushing force between the first pushing portion 111 and the second pushing member 21, and in the unlocked position 122, there is a second pushing force between the second pushing portion 112 and the second pushing member 21, and the driving rod 22 drives the second pushing member 21 to slide along the guide slide 113, so that the second pushing member 21 abuts against the first pushing portion 111 or the second pushing portion 112.

[0055] The second push member 21 slides along the outer periphery of the guide slide plate 113 while sliding. In the unlocking position 122, when the second push member 21 pushes and passes through the first push portion 111, the door body 40 approaches the box body 30, and there is a second push force between the second push portion 112 and the second push member 21. In the locking position, when the second push member 21 pushes and passes through the second push portion 112, the door body 40 moves away from the box body 30. The difference in distance between the first abutting portion in the first push member 11 and the second push portion 112 and the door body 40 is utilized to control the moving position of the driving rod 22 relative to the slide groove 12, thereby controlling the switching state of the door body 40, so as to further improve the convenience of use.

[0056] According to one embodiment of the present application, the guide slide 113 is an arc-shaped plate member that gradually approaches the door body 40 from the box body 30, and the first push portion 111 is located on the guide slide 113. Therefore, during the relative sliding process between the guide slide 113 and the second push member 21, friction loss can be further reduced, thereby increasing the service life. At the same time, the distance between the first push portion 111 and the second push portion 112 can be gradually changed, further reducing the driving force of the driving rod 22.

In the locked position, the cam surface 210 has a first diameter R1, and in the unlocked position 122, the cam surface 210 has a second diameter R2, wherein R1>R2. Figure 5 As shown, in the locked position, refer to Figure 1 and Figures 8-10 As shown, the first diameter R1 of the cam surface 210 in the cam portion 211 pushes against the second pushing portion 112, controlling the door body 40 to slide into the slide groove 12 away from the box body 30, and at the unlocking position 122, referring to Figure 2 and Figure 6 and Figure 7 As shown, the second diameter R2 of the cam surface 210 in the cam portion 211 is pushed against the second pushing portion 112 to control the door body 40 to slide into the slide groove 12 on the side close to the box body 30, and then, the radius difference of the cam surface 210 is utilized to realize the opening and closing state of the door body 40 relative to the box body 30 in the first direction 100.

[0058] According to one embodiment of the present application, the second push member 21 includes an extension portion 212, and the two ends of the extension portion 212 are respectively connected to the cam portion 211 and the driving rod 22. The extension portion 212 controls the diameter difference between the first diameter R1 and the second diameter R2 of the cam surface 210. The driving rod 22 is located at the center of the cam portion 211 and is used to drive the cam portion 211 to rotate, so that the cam portion 211 switches between the cam surface 210 with the first diameter R1 and the second diameter R2, thereby conveniently controlling the relative displacement of the door body 40 and the box body 30 in the first direction 100.

[0059] According to one embodiment of the present application, the mounting seat 10 includes a first assembly portion 13 and a second assembly portion 14, the first assembly portion 13 is connected to the box body 30, the first assembly portion 13 is provided with the first push member 11, the second assembly portion 14 is provided with the slide groove 12, and the first assembly portion 13 and the second assembly portion 14 are integrally formed and connected.

[0060] According to one embodiment of the present application, the first assembly portion 13 includes a support wall, the support wall 131 has a support surface 1311 facing the second resisting member, the first resisting member is disposed at one end of the support surface 1311, and the drive rod 22 drives the second resisting member to rotate on the support surface 1311. The support wall improves the stability of the cam portion 211 and the second resisting member during the rotation process.

[0061] According to one embodiment of the present application, the second assembly part 14 includes a first wall body 141 and a second wall body 142, the first wall body 141 forms a first limiting groove 1411 extending along the first direction 100, and the second wall body 142 forms a second limiting groove 1421, the first limiting groove 1411 is connected to the second limiting groove 1421, the locking position is located in the second limiting groove 1421, and the unlocking position 122 is located in the first limiting groove 1411, the second wall body 142 is an arc-shaped wall, and in the locking position, the second wall body 142 abuts against the outer periphery of the driving rod 22.

The driving mechanism can be set as a motor of the refrigerator, and the motor is used to drive the driving rod 22 to rotate, thereby driving the cam portion 211 to rotate, so that the cam portion 211 switches between the cam surface 210 of the first diameter R1 and the second diameter R2, so as to conveniently control the relative displacement of the door body 40 and the cabinet body 30 in the first direction 100.

[0063] According to another aspect of the present application, a refrigerator is provided, comprising the moving device.

[0064] According to one embodiment of the present application, it also includes a box body 30, a door body 40 and a driving assembly. The door body 40 is rotatably assembled on the door body 40. The moving device is arranged between the box body 30 and the door body 40. The driving rod 22 is assembled on the driving assembly to drive the driving rod 22 to move to the locking position through the driving assembly.

[0065] The innovation of this application is:

[0066] A refrigerator door opening and closing system is provided for use in refrigerators and freezers. During the door opening process, the door body 40 of the refrigerator and freezer first translates relative to the cabinet 30 and then rotates. During the door closing process, the door first rotates and then translates to close. This solves the following industry pain points of refrigerators and freezers:

[0067] 1. Solve the problem of strong door opening force and difficulty in opening the door due to negative pressure of refrigeration and freezing appliances;

[0068] 2. Solve the noise problem caused by the magnetic strip adsorption process when closing the door of refrigeration and freezing appliances;

[0069] 3. Solve the problem of hinged door sealing caused by deformation of the door body 40 and deformation and hardening of the door seal due to temperature changes;

[0070] 4. Solve the condensation problem caused by the door seal not being closed tightly;

[0071] In order to solve the above problems, the present application provides a moving device and a refrigerator, which first moves the door body 40 forward a certain distance through a translation device, and then rotates the door body 40, thereby reducing the effort required when the door body 40 is directly opened.

[0072] In a specific usage scenario:

[0073] The present application provides a door body 40 closing buffer system and a power-assisted door opening system for use in a refrigeration appliance. The refrigeration appliance door body 40 first translates relative to the cabinet 30 and then rotates during the door opening process. During the door closing process, the door body first rotates and then translates to close the door. In order to more clearly illustrate the implementation scheme of the present invention, the following will provide a detailed description of the drawings and installation steps required for this embodiment:

[0074] The refrigeration appliance provided in the above embodiment includes a door body 40 and a box body 30, wherein the box body 30 is provided with a compartment, and the door body 40 is connected to the box body 30 through a translation mechanism module, so that the door body 40 can move and rotate relative to the box body 30. Figure 7-10 As shown, in the process of opening the door 40, the door 40 needs to be translated outward (i.e., translated forward) for a distance relative to the box body 30. Figure 8 and Figure 9As shown, the sealing strip 50 on the door body 40 is separated from the box body 30, and then refer to Figure 10 As shown, the door body 40 is then rotated relative to the box body 30 to open the compartment. Since the door body 40 moves outward relative to the box body 30 during the opening process, there is a certain distance between the sealing strip 50 on the door body 40 and the box body 30. When the door body 40 drives the sealing strip 50 to rotate relative to the box body 30, the sealing strip 50 will not interfere with the box body 30.

[0075] In the process of closing the door 40, the door 40 must first be rotated relative to the box body 30. Figure 8 Then transformed to Figure 7 state, and then translate the door body 40 toward the box body 30 (i.e., translate backward) for a distance, so that the door body 40 closes the compartment. At this time, the door body 40 and the box body 30 are tightly matched through the sealing strip 50 to seal the compartment. Similarly, when the door body 40 closes the compartment and rotates relative to the box body 30, since there is a certain distance between the sealing strip 50 and the compartment at this time, the sealing strip 50 will not interfere with the box body 30.

[0076] like Figure 5 As shown, the mechanism for the translation of the experimental refrigerator door 40 is a cam mechanism, which uses the cam radius difference to achieve the translation of the door 40 relative to the box body 30. This cam mechanism is driven by a motor to overcome the negative pressure and the suction of the magnetic strip. After rotating half a circle, the hinge of the refrigerator itself rotates to realize the rotation of the door 40.

[0077] To sum up, the refrigerator provided by the above embodiment of the present invention, by setting a translation mechanism module, realizes that the door body 40 can rotate relative to the box body 30 and can move forward and backward relative to the box body 30. The door body 40 moves forward relative to the box body 30, so that there is a certain distance between the sealing strip 50 of the door body 40 and the box body 30, avoiding the occurrence of interference between the sealing strip 50 and the box body 30 when the door body 40 rotates relative to the box body 30, that is, the door seal is twisted, causing the sealing strip 50 to deform, resulting in poor sealing and cold leakage, leading to temperature fluctuations in the refrigerator, increased energy consumption and other problems.
