Referring to fig. 1 to 9, an embodiment of the present application provides a refrigerator including: the case 100, the door 200, and the automatic door opening and closing device.

Illustratively, the cabinet 100 defines a storage compartment of the refrigerator therein for storing articles. The storage compartment in the cabinet 100 may be divided into a refrigerating compartment and a freezing compartment. In order to facilitate taking and placing of the articles, the front side opening of the storage compartment is arranged.

Wherein the door 200 is rotatably connected with the case 100. Specifically, a door 200 is provided to the front side of the case 100 to close and open the storage compartment, and to take and put articles in the storage compartment. It should be noted that the number of the door bodies 200 may be one or two.

The automatic door opening and closing device is used for driving the door body 200 to rotate relative to the box body 100, so that the door body 200 can be automatically opened and closed. By providing the automatic door opening and closing device at the top of the cabinet 100, it is not necessary to occupy the storage space of the refrigerator. Moreover, the automatic door opening and closing device is positioned outside, so that the installation and maintenance of the automatic door opening and closing device are facilitated.

It can be appreciated that the number of the automatic door opening and closing devices may be identical to the number of the door bodies 200 near the top of the refrigerator, and the automatic door opening and closing devices are disposed in one-to-one correspondence with the door bodies 200, thereby realizing automatic opening and closing of the respective door bodies 200.

For example, the refrigerator may be provided with a voice recognition assembly, and when a user holds a heavy object with his/her hand to open and close the door, the user may control the door opening and closing device to open and close the door 200 through voice, or the user may control the angle of the door opening and closing device to open and close the door through voice.

In the present embodiment, the automatic door opening and closing apparatus includes a driving cylinder body 300, a first piston rod 400, a second piston rod 500, and a linkage 600.

Wherein the driving cylinder body 300 is located at the top of the case 100.

Specifically, the driving cylinder body 300 may be fixed to the top of the case 100 by a fixing clip.

It should be noted that the driving cylinder body 300 may be one of a cylinder body, a hydraulic cylinder body, or an electric cylinder body. The specific structure of the driving cylinder body 300 may be the same as that of the cylinder body, the hydraulic cylinder body or the electric cylinder body in the related art, and the structure and the working principle of the driving cylinder body 300 are not described in detail herein.

The first piston rod 400 is slidably connected with the driving cylinder body 300, the first piston rod 400 is inserted into the driving cylinder body 300, and the first piston rod 400 can slide along the axial direction of the first piston rod 400 relative to the driving cylinder body 300 so as to approach or separate from the driving cylinder body 300. The axial direction of the first piston rod 400 is collinear with the axis of the drive cylinder body 300.

Wherein the second piston rod 500 is rotatably connected to an end of the first piston rod 400 facing away from the driving cylinder body 300. It can be appreciated that when the door body 200 is opened, the motion track of the door body 200 is in an arc shape, and the track of the end of the second piston rod 500, which is away from the first piston rod 400, is in an arc shape by rotationally connecting the end of the second piston rod 500 with the end of the first piston rod 400, which is away from the driving cylinder body 300, so that the door body 200 can be effectively prevented from being blocked.

Wherein, the middle area of the linkage member 600 is rotatably connected with the case 100, one end of the linkage member 600 close to the second piston rod 500 is rotatably connected with the second piston rod 500, and one end of the linkage member 600 close to the door body 200 is slidably connected with the door body 200 along the width direction of the door body 200.

It should be noted that, the position between the two ends of the linkage member 600 is the middle area. That is, the connection position of the coupling member 600 and the case 100 is located between the connection position of the coupling member 600 and the second piston rod 500 and the connection position of the coupling member 600 and the door 200.

The driving cylinder body 300 is used for driving the linkage member 600 to rotate relative to the case 100 through the first piston rod 400 and the second piston rod 500, and slides in the width direction relative to the door body 200 to open or close the door body 200. The width direction of the refrigerator is the direction shown by the X axis in the figure.

For example, as shown in fig. 4 to 9, when the door is opened, the driving cylinder body 300 drives the first piston rod 400 and the second piston rod 500 to move toward the driving cylinder body 300, and the second piston rod 500 drives the interlocking piece 600 to rotate clockwise and drives the interlocking piece 600 to slide toward the connection position of the door body 200 and the case 100 in the width direction of the refrigerator, thereby opening the door body 200.

When the door is closed, the driving cylinder body 300 drives the first piston rod 400 and the second piston rod 500 to move away from the driving cylinder body 300, the second piston rod 500 drives the linkage 600 to rotate anticlockwise, and drives the linkage 600 to slide along the width direction of the refrigerator away from the connection position of the door body 200 and the box body 100, so that the door body 200 is opened.

It should be noted that, in other embodiments, the setting positions of the driving cylinder body 300, the first piston rod 400, the second piston rod 500 and the linkage member 600 are different, and the specific action process when the refrigerator is opened or closed is different, which is not described herein.

In some embodiments of the present application, the length of the driving cylinder body 300 along the extending direction is greater than the length of the first piston rod 400 along the extending direction, and the driving cylinder body 300 drives the first piston rod 400 and the second piston rod 500 to move toward the driving cylinder body 300, so that the first piston rod 400 and a part of the second piston rod 500 are located in the driving cylinder body 300.

Referring to fig. 9, the first piston rod 400 and a part of the second piston rod 500 are located in the driving cylinder body 300, so that the driving cylinder body 300 can play a limiting role, and the door body 200 has better stability of the door opening angle and is not easy to shake. Moreover, the structure provided by the present embodiment is advantageous in that the overall size of the first piston rod 400, the second piston rod 500 and the driving cylinder body 300 can be reduced, compared to the case where a conventional piston cylinder is employed, in which the second piston rod 500 is hinged to the piston rod of the piston cylinder, so that the space occupation can be reduced.

The extending direction of the cylinder body 300 is an axial direction. The first piston rod 400 is axially directed in the extension direction.

Referring to fig. 3 and 10, in some embodiments of the present application, the refrigerator further includes a fixing member 700, and the sliding connection of the interlocking member 600 with the door body 200 is achieved by the fixing member 700.

Specifically, the fixing member 700 is connected to the door body 200, the fixing member 700 has a sliding track 710, an extending direction of the sliding track 710 is consistent with a width direction, and one end of the linking member 600, which is close to the door body 200, is located in the sliding track 710 and slidably connected to the fixing member 700.

For example, the fixing member 700 may be adhered to the door body 200, or the fixing member 700 may be coupled to the door body 200 by a screw.

In this embodiment, the fixing member 700 includes a first connecting portion 720 and a second connecting portion 730 that are connected to each other, the first connecting portion 720 is located at a position near the top of one side of the door body 200 facing the box body 100, the first connecting portion 720 is connected to the door body 200, and a hollow-out slideway 710 is formed on the second connecting portion 730.

It can be appreciated that by providing the fixing member 700, the sliding way 710 is not required to be provided on the door body 200, so that the influence on the door body 200 can be reduced, and the installation and the disassembly of the linkage member 600 are facilitated.

In some embodiments, the second connecting portion 730 is further provided with a weight-reducing groove 731, the slideway 710 and the weight-reducing groove 731 are spaced apart, and the extending directions of the slideway 710 and the weight-reducing groove 731 are consistent. In this way, the weight of the fixing member 700 can be reduced, thereby reducing the influence of the fixing member 700 on the door body 200.

Referring to fig. 3 and 11, in some embodiments of the present application, a first mounting portion 610 and a second mounting portion 620 are disposed at intervals along a length direction of the door body 200 at one end of the linking member 600 near the door body 200. Wherein the first mounting portion 610 and the second mounting portion 620 are adapted to slidably couple with the fixture 700.

Specifically, a first mounting hole matched with the slideway 710 is formed in the first mounting portion 610, a second mounting hole matched with the slideway 710 is formed in the second mounting portion 620, the fixing member 700 is located between the first mounting portion 610 and the second mounting portion 620, and the first connecting member penetrates through the first mounting hole and the slideway 710 in sequence. Part of the first connecting piece is located in the slideway 710 and can slide along the extending direction of the slideway 710. Thus, the connecting structure of the linkage member 600 and the fixing member 700 is simple, and the reliability of connection is high.

Wherein, first mounting hole and second mounting hole can be the unthreaded hole, and are the through-hole. The first connector may be a bolt assembly including a screw and a nut. Alternatively, the first mounting hole and the second mounting hole may be light holes, wherein the first mounting hole is a through hole, the second mounting hole is a blind hole, and the first connecting piece may be a pin shaft. Or, the first mounting hole is a unthreaded hole and is connected with the through hole, the second mounting hole is a threaded hole, and the first connecting piece is a screw. The present embodiment is not particularly limited herein.

Referring to fig. 3, in some embodiments of the present application, in order to facilitate the rotational connection of the linkage 600 and the case 100, the refrigerator further includes a fixing base 800, and the fixing base 800 is connected to the case 100. For example, the fixing may be performed by screw connection or by bonding.

The second connector may be a pin, for example.

It will be appreciated that this connection is relatively simple and efficient to manufacture and install. By providing the fixing base 800, there is no need to provide a fourth mounting hole in the case 100, and the influence on the overall structure of the case 100 can be reduced.

In some embodiments of the present application, a fourth mounting portion 640 is disposed at an end of the third mounting portion 630 facing away from the second mounting portion 620, and the fourth mounting portion 640 is configured to be rotatably connected to the second piston rod 500.

Wherein the fourth mounting portion 640 is rotatably connected to an end of the second piston rod 500 facing away from the first piston rod 400.

Wherein the axial distance from the axis of the fourth mounting portion 640 to the axis of the third mounting portion 630 is smaller than the axial distance from the axis of the second mounting portion 620 to the axis of the third mounting portion 630. It can be appreciated that, in this way, on the premise that the interlocking member 600 is ensured to be capable of fully opening the door body 200, that is, on the condition that the distance from the axis of the second mounting portion 620 to the axis of the third mounting portion 630 is fixed, the length of the interlocking member 600 can be effectively reduced, so that the space occupation can be reduced and the cost can be reduced.

It should be noted that the structure of the fourth mounting portion 640 may include the same structure as the first mounting portion 610 and the second mounting portion 620, and the structure and the principle are the same, which is not described herein.
