[0031] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0032] The refrigerator flip beam is widely used in multi-door and French-style refrigerators. The refrigerator flip beam is fixed on the single door of the refrigerator and can be freely flipped along the rotating axis between perpendicular to the door and parallel to the door. It can be simply understood as a vertical beam that can rotate 90° in the vertical direction. Generally, when the door is opened, the refrigerator flip beam moves along the guide groove on the refrigerator body to become perpendicular to the door; when the door is closed, the refrigerator flip beam moves along the guide groove on the refrigerator body to become parallel to the door, so that it can be precisely matched with the seals on the left and right door bodies, so that a relatively closed space is formed between the box and the door body to achieve the purpose of preserving cold air.

[0033] Among them, when the door is opened, the refrigerator flip beam moves along the guide groove on the refrigerator body to become perpendicular to the door body, and the inner side of the flip beam contacts the side of the door body, which will produce impact noise. Some refrigerators will add rubber blocks on the inner side of the flip beam, using the elastic deformation of the rubber blocks to reduce shock. Although it can play a certain buffering role, there is still a one-time direct collision between the door body and the rubber block pad surface. The obvious noise brings a harsh and unpleasant experience to the user, and cannot effectively solve the technical problem of the impact noise generated by the flip beam when the door is opened.

[0034] Therefore, the present disclosure provides a shock-absorbing pad, a flip beam shock-absorbing and noise-reducing structure, and a refrigerator, which can reduce the impact noise generated when the flip beam opens the door.

[0035] Next, the embodiments of the present disclosure are described in detail.

[0036] like Figure 1A and Figure 1B As shown, Figure 1A is a schematic structural diagram of a shock-absorbing pad according to an exemplary embodiment. Figure 1B is another structural schematic diagram of a shock-absorbing pad according to an exemplary embodiment.

[0037] Figure 1A and Figure 1B The shock-absorbing pad includes a head portion 11 , a mounting portion 12 , and an air groove 13 , wherein the air groove 13 includes a first type of air groove 131 and a second type of air groove 132 .

[0038] The shock-absorbing pad includes a mounting portion 12 and a head portion 11 . The shock-absorbing pad is mounted on a flip beam of the refrigerator via the mounting portion 12 . The head portion 11 is provided with at least one first type air groove 131 and / or at least one second type air groove 132 .

[0039] When the flip beam flips due to the opening of the door body, the first type of air groove 131 cooperates with the surface of the flip beam shell to form a closed air cavity, and the second type of air groove 132 cooperates with the surface formed on the side of the refrigerator door to form a closed air cavity.

[0040] Specifically, in an embodiment of the present disclosure, a shock-absorbing pad including a head portion 11 and a mounting portion 12 is provided on the flip beam of the refrigerator, and the shock-absorbing pad is installed on the flip beam of the refrigerator through the mounting portion 12. The head portion 11 of the shock-absorbing pad is provided with an air groove 13, and the air groove 13 includes at least one first-type air groove 131 and at least one second-type air groove 132. In some other embodiments, only at least one first-type air groove 131 or only at least one second-type air groove 132 may be included. The shock-absorbing pad shown in FIG. 1 in the embodiment of the present disclosure includes one first-type air groove 131 and two second-type air grooves 132.

[0041] When the flip beam flips due to the door opening, the first type of air grooves 131 and the second type of air grooves 132 respectively contact different surfaces of the refrigerator, thereby forming a closed air cavity.

[0042] like Figure 2 As shown, Figure 2 FIG. 1 is a schematic cross-sectional view of a shock-absorbing pad according to an exemplary embodiment. Figure 2 It can be seen that the first type of air groove 131 and the second type of air groove 132 are respectively located at the upper and lower sides of the shock absorbing pad head 11, the first type of air groove 131 is located at the lower side of the shock absorbing pad head 11, and the second type of air groove 132 is located at the upper side of the shock absorbing pad head 11, and the opening directions of the two are opposite. Among them, the lower side of the head 11 of the shock absorbing pad is the side connected to the mounting portion 12, and the other opposite side is the upper side of the shock absorbing pad head 11.

[0043] In an exemplary embodiment, the head 11 of the shock absorbing pad includes at least one first type air groove 131 and at least one second type air groove 132 . In some other embodiments, it may include only multiple first type air grooves 131 or only multiple second type air grooves 132 .

[0044] By providing a plurality of air grooves 13, when the inner side of the flip beam collides with the side of the refrigerator door, the two types of air grooves 13 can cooperate with the surface of the flip beam shell and / or the surface formed by the side of the refrigerator door to form multiple air cavities, thereby increasing the shock-absorbing structure of the shock-absorbing pad and further improving the noise reduction and shock-absorbing effect of the shock-absorbing pad.

[0045] In some other embodiments, those skilled in the art may adjust the number of the air slots 13 as required, and the present disclosure does not limit the number of the air slots 13 .

[0046] In an exemplary embodiment, the first type of air grooves 131 and the second type of air grooves 132 are annular air grooves.

[0047] Specifically, as shown in FIG1 , the first type of gas groove 131 and the second type of gas groove 132 in FIG1 are both annular gas grooves, which are evenly distributed on the upper and lower sides of the cylindrical head 11. Compared with gas grooves of other shapes, the gas grooves 13 are set as annular gas grooves, which can evenly distribute the pressure of the gas, and when the two types of gas grooves 13 cooperate with the surface formed by the flip beam shell surface or the side of the refrigerator door to form a sealed cavity, the gas in the sealed cavity can be more stable, and the sealing performance can be better guaranteed, thereby improving the shock absorption and noise reduction effect of the shock absorbing pad 10.

[0048] In some other embodiments, the shape of the air groove 13 may also be adjusted, for example, changed to a square air groove or an irregularly shaped air groove, etc. Those skilled in the art may modify and adjust the specific shape of the air groove 13 as needed, and the present disclosure does not limit this.

[0049] In an exemplary embodiment, when the head 11 is provided with a plurality of air grooves 13 , the plurality of air grooves 13 are nested.

[0050] When the number of air grooves 13 provided on the head 11 of the shock absorbing pad exceeds one, the plurality of air grooves 13 are arranged in a nested structure. As shown in FIG. 1 , the head 11 of the shock absorbing pad is provided with two second-type air grooves 132 and one first-type air groove 131, wherein one second-type air groove 132 is arranged around another second-type air groove 132, and the two form a nested structure. Figure 2 It can be seen that the first type of air grooves 131 of the shock-absorbing pad are arranged around the two second type of air grooves 132 mentioned above, and the three air grooves 13 are in a concentric circle nested structure.

[0051] Through the nested arrangement structure between the plurality of air grooves 13 , the air grooves at the head can be arranged compactly, thereby improving the utilization rate of the space at the head 11 of the shock-absorbing pad.

[0052] In some other embodiments, the depth of the multiple air grooves 13 can be adjusted according to structural requirements, and the multiple air grooves may not be nested with the same point as the center. Those skilled in the art can change the relative position between the first type of air grooves 131 and the second type of air grooves 132 as needed. The present disclosure does not limit the arrangement structure between the multiple air grooves 13.

[0053] In addition, when the multiple air slots 13 are in a shape that cannot be nested, those skilled in the art may use other arrangement structures according to needs, such as horizontal arrangement or scattered arrangement, etc., and the present disclosure does not limit this.

[0054] like Figure 3 As shown, Figure 3 is a schematic diagram of placement of shock-absorbing pads according to an exemplary embodiment. Figure 3 The invention comprises a shock absorbing pad 10 , a flip beam 31 and a shock absorbing matching plate 32 .

[0055] In an exemplary embodiment, the surface formed by the side of the refrigerator door includes: the side of the refrigerator door, or the shock-absorbing matching plate 32 installed on the side of the refrigerator door.

[0056] Specifically, if Figure 3As shown, in the embodiment of the present disclosure, when the flip beam 31 flips due to the door opening, the second type of air groove 132 cooperates with the surface of the shock-absorbing matching plate 32 installed on the side of the refrigerator door to form a closed air cavity. The position of the shock-absorbing matching plate 32 on the side of the door corresponds to the position of the shock-absorbing pad 10 on the flip beam 31.

[0057] By setting the shock-absorbing matching plate 32 and the shock-absorbing pad 10 to form a shock-absorbing and noise-reducing structure, the impact noise generated when the flip beam 31 opens the door is reduced. At the same time, the shock-absorbing pad 10 does not directly contact and collide with the side of the door body 50, thereby protecting the side of the door body and avoiding damage caused by frequent impacts.

[0058] In some other embodiments, the second type of air groove 132 may also be directly matched with the side surface of the refrigerator door to form a closed air cavity, which is not limited in the present disclosure.

[0059] At least a portion of the head 11 of the shock-absorbing pad 10 exceeds the surface of the shell of the flip beam 31. When the flip beam 31 of the refrigerator flips due to the door opening, the shock-absorbing pad 10 contacts and collides with the corresponding position of the shock-absorbing matching plate 32. When the shock-absorbing pad 10 contacts the shock-absorbing matching plate 32, the first type of air groove 131 cooperates with the surface of the shell of the flip beam 31 to form a closed air cavity, and the second type of air groove 132 cooperates with the surface of the shock-absorbing matching plate 32 located on the side of the refrigerator door to form a closed air cavity.

[0060] In an exemplary embodiment, the first type of air groove 131 is an air groove opening toward one side of the shell surface of the flip beam 31, and the second type of air groove 132 is an air groove opening toward one side of the surface formed by the side of the refrigerator door.

[0061] Depend on Figure 3 It can be seen that when the shock-absorbing pad 10 is assembled to the flip beam 31 through the mounting portion 12, the first type of air groove 131 located on the lower side of the head 11 of the shock-absorbing pad 10 opens toward the side of the shell surface of the flip beam 31, while the second type of air groove 132 located on the upper side of the head 11 of the shock-absorbing pad 10 opens toward the side of the surface of the shock-absorbing matching plate 32.

[0062] In some other embodiments, the opening directions of the first type of air grooves 131 and the second type of air grooves 132 can be adjusted according to the actual positions of the flip beam 31 and the shock-absorbing matching plate 32. Under the premise that the air grooves 13 ultimately need to form closed cavities with the two surfaces respectively, those skilled in the art may also modify and adjust the specific opening directions.

[0063] like Figure 4 As shown, Figure 4 is a schematic diagram of a cross section of a flip beam when a shock-absorbing pad is placed according to an exemplary embodiment. Figure 4The flip beam 31 includes a mounting portion 12 of the shock-absorbing pad 10 , a first type of air groove 131 , the first type of air groove 131 , and an assembly hole 40 located on the flip beam 31 .

[0064] In an exemplary embodiment, an assembly hole 40 is provided on the flip beam 31 , and the mounting portion 12 of the shock-absorbing pad is adapted to fit into the assembly hole 40 provided on the flip beam 31 .

[0065] Specifically, in order to set the shock-absorbing pad 10 on the inner side of the flip beam 31, an assembly hole 40 for installing the shock-absorbing pad 10 is provided on the flip beam 31. The assembly hole 40 is a hole groove extending from the surface of the flip beam 31 to the inside of the flip beam 31. It should be pointed out that the internal structure of the assembly hole 40 is adapted to the shape of the mounting portion 12 of the shock-absorbing pad 10, and is used to lock the mounting portion 12 in the assembly hole 40 to prevent it from falling off easily.

[0066] In an exemplary embodiment, the cross section of the shock-absorbing pad mounting portion 12 is cross-shaped, the assembly hole 40 includes a receiving groove and a limiting protrusion, and the mounting portion 12 is engaged with the assembly hole 40 .

[0067] like Figure 4 As shown, in the embodiment of the present disclosure, the shock-absorbing pad mounting portion 12 is a slender rod, specifically, its cross-section is cross-shaped, that is, the diameter of the portion where the mounting portion 12 contacts the head 11 is smaller than the maximum diameter of the mounting portion 12 as a whole, and a protruding portion in the shape of an inverted cone is provided in the middle section of the mounting portion 12, which makes the cross-section of the shock-absorbing pad mounting portion 12 cross-shaped.

[0068] In order to adapt to the shape of the mounting portion 12, the assembly hole 40 shown includes two parts: a receiving groove and a limiting protrusion. The receiving groove is used to accommodate the raised portion of the mounting portion and the structure below it, and the limiting protrusion is clamped in the structure between the raised structure and the head in the mounting portion to prevent the mounting portion from slipping out of the assembly hole 40, thereby playing a reinforcing role.

[0069] In some other embodiments, the shape of the raised structure on the shock-absorbing pad mounting portion 12 may be other shapes such as a cylinder, and the number of raised structures may be multiple, while the assembly hole 40 may be changed accordingly to adapt to the shape of the mounting portion 12. Those skilled in the art may make corresponding adjustments to the structures of the mounting portion 12 and the assembly hole 40 as required, and the present disclosure does not impose any restrictions on this.

[0070] In the embodiment of the present disclosure, a shock-absorbing pad 10 having a head 11 with at least one first-type air groove 131 and / or at least one second-type air groove 132 is arranged on the flip beam 31 of the refrigerator, so that when the flip beam 31 flips due to the opening of the door body 50, the first-type air groove 131 cooperates with the shell surface of the flip beam 31 to form a closed air cavity, and the second-type air groove 132 cooperates with the surface formed on the side of the refrigerator door body to form a closed air cavity. The closed air cavity is compressed to generate air pressure, which reduces the contact vibration between the flip beam 31 and the door body 50, thereby reducing the impact noise generated when the flip beam 31 opens the door.

[0071] The embodiments of the present disclosure further provide a flip beam shock-absorbing and noise-reducing structure, comprising: a shock-absorbing pad as described in the above embodiments.

[0072] Specifically, when the door body 50 is opened, the shock-absorbing pad head 11 on the inner side of the flip beam 31 will contact and collide with the surface formed by the side of the refrigerator door body corresponding to the position of the shock-absorbing pad 10 on the side of the refrigerator door body, and the second type of air groove 132 on the shock-absorbing pad head 11 cooperates with the surface formed by the side of the refrigerator door body to form a closed air cavity, and the first type of air groove 131 on the shock-absorbing pad head 11 cooperates with the surface of the flip beam 31 to form a closed air cavity, generating air pressure, thereby reducing the contact vibration between the flip beam 31 and the door body 50, thereby reducing the impact noise generated when the flip beam opens the door.

[0073] Among them, it should be pointed out that the air grooves 13 on the shock-absorbing pad 10 are all air grooves 13 adapted to the surface of the flip beam 31 or the surface formed by the side of the refrigerator door body, that is, when the door body 50 is opened and the flip beam 31 flips and hits the door body, the air grooves on the shock-absorbing pad 10 can just form a closed air cavity with the surface of the flip beam 31 or the surface formed by the side of the refrigerator door body.

[0074] In an exemplary embodiment, the first type of air groove 131 abuts against the surface of the flip beam shell before and after flipping to form a closed air cavity; or, there is a gap between the first type of air groove 131 and the surface of the flip beam shell 31 before flipping, and when the flip beam is flipped due to the opening of the door body, the shock-absorbing pad is squeezed to abut against the surface of the flip beam shell and form a closed air cavity.

[0075] In the embodiments of the present disclosure, Figure 4 As shown, the first type of air groove 131 and the surface of the flip beam 31 are already in contact with each other before the flip beam 31 flips, forming a closed air cavity. When the door body 50 is opened and the flip beam 31 flips, the first type of air groove 131 and the closed air cavity on the surface of the flip beam 31 are squeezed to generate air pressure. By setting the closed air cavity before the flip beam 31 flips, the air cavity is directly compressed when the flip beam 31 flips and collides, and the airtightness is better, further improving the shock-absorbing and noise-reducing capabilities of the shock-absorbing pad 10.

[0076] In another embodiment, there is a gap between the first type of air groove 131 and the shell surface of the flip beam 31 before flipping. When the flip beam 31 flips due to the opening of the door body 50, the shock-absorbing pad 10 is squeezed after colliding with the surface formed by the side of the refrigerator door body. The first type of air groove 131 moves to one side of the flip beam 31 surface and abuts against the shell surface of the flip beam 31, forming a closed air cavity between the two, and the closed air cavity is squeezed to generate air pressure.

[0077] Through the above two embodiments, when the flip beam 31 flips due to the opening of the door body 50, the first type of air groove 131 and the surface of the flip beam 31 form a closed air cavity, which reduces the contact vibration between the flip beam 31 and the door body 50, thereby reducing the impact noise generated by the flip beam 31 when the door is opened. The present disclosure does not limit which of the above methods is used to form the closed air cavity.

[0078] In an exemplary embodiment, the flip beam shock-absorbing and noise-reducing structure further includes the shock-absorbing matching plate 32 , wherein the shock-absorbing matching plate 32 is an integral structure with any rotating shaft between the flip beam 31 and the door body 50 .

[0079] like Figure 3 As shown, at least one rotating shaft is provided between the flip beam 31 and the door body 50 for connecting the two, and the shock-absorbing matching plate 32 is connected to the rotating shaft and is an integrated structure with the rotating shaft. By integrating the shock-absorbing matching plate 32 with the rotating shaft, the assembly efficiency and structural strength are improved. At the same time, since the rotating shaft is the vibration source, the shock-absorbing and noise-reducing structure of the flip beam close to the rotating shaft can directly reduce the impact of the vibration of the flip beam on the surrounding structure compared to that set at other positions, and the anti-seismic and noise-reducing effect is more obvious.

[0080] In some other embodiments, the shock-absorbing matching plate 32 and the rotating shaft can also be installed in two parts, and the shock-absorbing matching plate 32 can be independently set at a position corresponding to the shock-absorbing pad 10 on the side of the refrigerator door, and the present disclosure does not limit this.

[0081] At the same time, those skilled in the art can change the position of the flip beam shock-absorbing and noise-reducing structure on the flip beam 31 and the door body 50 as needed, and the present disclosure does not limit this.

[0082] An embodiment of the present disclosure further provides a refrigerator, comprising at least one flip beam shock-absorbing and noise-reducing structure as described in the above embodiment.

[0083] In the embodiments of the present disclosure, a plurality of flip beam shock-absorbing and noise-reducing structures may be provided on the flip beam, and the present disclosure does not impose any limitation on this.

[0084] Next, an overall description is given of the process in which the refrigerator's flipping beam 31 flips over due to the opening of the door and contacts the side of the refrigerator door, wherein it is assumed that the first type of air groove 131 abuts against the surface of the flipping beam 31 before flipping, and the surface formed by the side of the refrigerator door is the shock-absorbing matching plate 32.

[0085] like Figure 5A As shown, Figure 5A 1 is a schematic diagram of the flip beam before flipping when the door is opened according to an exemplary embodiment. When the flip beam 31 is not flipped, the refrigerator door body 50 is closed. At this time, the refrigerator flip beam 31 is parallel to the door body 50, and the second type of air groove 132 of the shock-absorbing pad 10 does not contact the surface of the shock-absorbing matching plate 32, and does not form a closed air cavity with the surface of the shock-absorbing matching plate 32; the first type of air groove 131 abuts against the surface of the flip beam 31 before flipping, and forms a closed air cavity with the shell surface of the flip beam 31.

[0086] like Figure 5B As shown, Figure 5B The diagram is a schematic diagram of the flipping of the flip beam when the door is opened according to an exemplary embodiment. During the flipping process of the flip beam 31, the refrigerator door body 50 is opened, and the refrigerator flip beam 31 slowly changes from horizontal to inclined relative to the door body 50. The shock-absorbing pad 10 approaches the shock-absorbing matching plate but does not contact the surface of the shock-absorbing matching plate 32, and does not form a closed air cavity with the surface of the shock-absorbing matching plate 32; the first type of air groove 131 abuts against the surface of the flip beam 31, and forms a closed air cavity with the shell surface of the flip beam 31.

[0087] like Figure 5C As shown, Figure 5C This is a schematic diagram of the flip beam after flipping when the door is opened according to an exemplary embodiment. After the flip beam 31 is flipped, the refrigerator door 50 is opened, and the refrigerator flip beam 31 is perpendicular to the door 50. The second type of air groove 132 of the shock-absorbing pad 10 contacts the surface of the shock-absorbing matching plate 32, and forms a closed air cavity with the surface of the shock-absorbing matching plate 32, and compresses the gas in the air cavity to generate air pressure; the first type of air groove 131 abuts against the surface of the flip beam 31, and forms a closed air cavity with the shell surface of the flip beam 31, and the closed air cavity is directly squeezed to generate air pressure. The air pressure is generated by squeezing the closed air cavity, and the shock and noise reduction of the flip beam 31 when it hits is completed.

[0088] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the disclosure disclosed herein. The present disclosure is intended to cover any variations, uses or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art that are not disclosed in the present disclosure. The description and examples are intended to be exemplary only, and the true scope and spirit of the present disclosure are indicated by the claims.

[0089] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
