[0004] This application provides a door seal and a housing assembly to solve the problem that the existing door seal is too thick to be used in application scenarios where the distance between the door and the housing is small.

[0005] To address the aforementioned technical problems, this application provides a door seal applied to a cabinet assembly. When the door of the cabinet assembly is closed, the distance between the outer peripheral sidewall of the door near the cabinet and the cabinet is 6mm to 7mm. The door seal includes a supporting airbag and a fastener. The supporting airbag is positioned between the outer peripheral sidewall and the cabinet. The fastener is connected to the outer sidewall of the supporting airbag near the door and is configured to engage with the door. In the arrangement direction of the supporting airbag and the fastener, the supporting airbag has a supporting rib located away from the inside of the fastener. The supporting rib is configured to abut against the sidewall of the supporting airbag near the cabinet when the door is closed. The dimension of the supporting airbag in the arrangement direction is 8.5mm to 10mm.

[0006] In one embodiment, in the arrangement direction, a first airbag with an isolating arrangement is formed on the inner wall of the support airbag near the buckle member, and the support rib is located at the end of the first airbag away from the buckle member.

[0007] In one embodiment, the support rib includes two sub-support ribs. In the direction perpendicular to the arrangement direction, one end of the two sub-support ribs is spaced apart from the first airbag, wherein the distance between one end of the two sub-support ribs is less than the distance between the other ends of the two sub-support ribs.

[0008] In one embodiment, a second airbag is also formed inside the supporting airbag, which is disposed opposite to the first airbag. When the door is in the closed state, the two sub-support ribs and the second airbag form a sealed cavity.

[0009] In one embodiment, the door seal further includes a first wing and a second wing. The first wing is connected to the outer wall of the support airbag away from the buckle and is close to one end of the support airbag perpendicular to the arrangement direction. The first wing is configured to abut against the outer side of the housing. The second wing is connected to the other end of the support airbag perpendicular to the arrangement direction. The second wing is configured to abut against the inner side of the housing.

[0010] In one embodiment, the second wing edge is also provided with an auxiliary airbag.

[0011] In one embodiment, the door seal further includes a third wing, which is connected to the outer wall of the supporting airbag and is disposed on the same side as the buckle, and the third wing is configured to abut against the door body.

[0012] In one embodiment, the fastener includes a vertical airbag and a limiting inverted wing, the vertical airbag extending along the arrangement direction; the limiting inverted wing is located at the end of the vertical airbag opposite to the supporting airbag in the arrangement direction.

[0013] In one embodiment, the fastener further includes an abutting wing edge connected to the end of the limiting inverted wing that is away from the supporting airbag.

[0014] To address the aforementioned technical problems, this application provides a cabinet assembly, which includes a cabinet, a door, and a door seal. The cabinet has a storage cavity and an opening communicating with the storage cavity. The door is connected to the cabinet and configured to open and close the opening. In any of the above embodiments, the door seal is connected to the side of the door facing the opening. The distance between the outer peripheral sidewall of the door near the cabinet and the cabinet is 6mm to 7mm.

[0015] The beneficial effects of this application are as follows: This application provides a door seal for a cabinet assembly, wherein when the door of the cabinet assembly is closed, the distance between the outer peripheral sidewall of the door near the cabinet and the cabinet is 6mm to 7mm. The door seal includes a support airbag and a fastener. The support airbag is configured to be disposed between the outer peripheral sidewall and the cabinet. The fastener is connected to the outer side of the support airbag near the door and is configured to engage with the door. In the arrangement direction of the support airbag and the fastener, the support airbag has a support rib located away from the inside of the fastener. The support rib is configured to abut against the sidewall of the support airbag near the cabinet when the door is closed. The size of the support airbag in the arrangement direction is 8.5mm to 10mm. The supporting airbag of the door seal in this application has a dimension of 8.5mm to 10mm in the arrangement direction. It can be applied to cabinet components with a small distance between the outer peripheral sidewall of the door and the cabinet body, thereby increasing the storage capacity of the cabinet component or reducing the volume of the cabinet component without changing the capacity. In addition, when the door is closed, the supporting airbag is compressed, and the supporting ribs inside the supporting airbag abut against the sidewall of the supporting airbag near the cabinet body, or in other words, the supporting ribs abut against the cabinet body through the sidewall of the supporting airbag. Thus, the supporting ribs can support the supporting airbag, preventing severe deformation of the supporting airbag. This allows the supporting airbag to fit tightly against the cabinet body and the door body, thereby enhancing the sealing performance of the cabinet body and the door body. This reduces the leakage of cold or heat inside the cabinet, improves the thermal insulation quality of the cabinet component, and can also reduce energy consumption in applications that require energy-consuming thermal insulation.

[0021] This application provides a door seal for a cabinet assembly. The door seal is a sealing element disposed between the door and the cabinet assembly. Its main function is to seal the gap between the door and the cabinet when the door is closed, thereby slowing down the rate of heat loss from the interior of the cabinet and achieving long-term heat preservation of the cabinet assembly. (See reference) Figures 1 to 3The door seal 300 includes a supporting airbag 310 and a fastener 320. The supporting airbag 310 is configured between the outer peripheral side wall of the door body 100 and the housing 200. The fastener 320 is connected to the supporting airbag 310 near the outer side wall of the door body 100 and is configured to engage with the door body 100. In the arrangement direction X of the supporting airbag 310 and the fastener 320, the supporting airbag 310 has a supporting rib 311 inside, away from the fastener 320. The supporting rib 311 is configured to abut against the side wall of the supporting airbag 310 near the housing 200 when the door body 100 is closed. The dimension of the supporting airbag 310 in the arrangement direction X is 8.5mm to 10mm. For example, the dimension of the supporting airbag 310 in the arrangement direction X can be 8.5mm, 9mm, 9.5mm, 10mm, etc.

[0022] The outer peripheral sidewall of the door 100 refers to the portion of the sidewall of the door 100 facing the opening 210 of the housing 200 near the outer periphery of the door 100. The door seal 300 is disposed on the outer peripheral sidewall of the door 100 to enhance the sealing between the door 100 and the housing 200.

[0023] When the door seal 300 is connected to the door body 100, the arrangement direction X of the fastener 320 and the support airbag 310 is parallel to the direction from the door body 100 to the box body 200, or in other words, the arrangement direction X of the fastener 320 and the support airbag 310 is parallel to the setting direction of the door body 100 and the box body 200.

[0024] The door seal 300 can be made of ordinary polyvinyl chloride (PVC) material, or it can be made of materials with lower thermal conductivity, such as foamed PVC or foamed thermoplastic elastomer (TPE). There are no restrictions on this.

[0025] The supporting airbag 310 of the door seal 300 of this application has a dimension of 8.5mm to 10mm in the X-direction. It can be applied to a cabinet assembly 10 (not shown in the figure) where the distance between the outer peripheral sidewall of the door 100 and the cabinet 200 is small. This allows the storage cavity capacity to be increased without changing the volume of the cabinet assembly 10, or the volume of the cabinet assembly 10 to be reduced without changing the capacity. In addition, when the door 100 is in the closed state, the supporting airbag 310 is compressed, and the supporting rib 311 inside the supporting airbag 310 is close to the cabinet. The side wall of the body 200 abuts against, or in other words, the support rib 311 abuts against the side wall of the support airbag 310, thereby providing support for the support airbag 310. This prevents severe deformation of the support airbag 310, allowing it to fit tightly against the body 200 and the door 100, thus enhancing the sealing performance of the body 200 and the door 100. This reduces the leakage of cold or heat within the body 200, improves the insulation quality of the body assembly 10, and reduces energy consumption in applications requiring energy-intensive insulation. In other words, the door seal 300 of this application is small in size while maintaining a good sealing performance.

[0026] In one embodiment, in the arrangement direction X of the buckle 320 and the support airbag 310, a first airbag 312 is formed on the inner side wall of the support airbag 310 near the buckle 320, and a support rib 311 is provided at the end of the first airbag 312 away from the buckle 320.

[0027] Understandably, inside the supporting airbag 310, and on the inner sidewall of the supporting airbag 310 opposite to the fastener 320, the supporting airbag 310 also forms an isolating first airbag 312. The supporting rib 311 is located on the side of the first airbag 312 opposite to the fastener 320. In this embodiment, by forming the first airbag 312 inside the supporting airbag 310, the first airbag 312 can further provide support in the arrangement direction X, preventing severe deformation of the supporting airbag 310 and allowing it to fit tightly against the box 200 and the door 100, thereby enhancing the sealing performance of the box 200 and the door 100. Furthermore, the first airbag 312 can extend the heat conduction path, thereby reducing the leakage of cold or heat within the box 200, improving the insulation quality of the box assembly 10, and reducing energy consumption in applications requiring energy-intensive insulation.

[0028] In one embodiment, the support rib 311 includes two sub-support ribs 311, which are perpendicular to the arrangement direction X in the direction Y. One end of the two sub-support ribs 311 is spaced apart from the first airbag 312, wherein the distance between one end of the two sub-support ribs 311 is less than the distance between the other ends of the two sub-support ribs 311.

[0029] In this embodiment, the first distance between one end of the two sub-support ribs 311 is less than the distance between the other ends of the two sub-support ribs 311, which can be understood as the other ends of the two sub-support ribs 311 being arranged in a trumpet shape. When the door 100 is in the closed state, the support airbag 310 is compressed and deformed, and the other ends of the two sub-support ribs 311 abut against the box 200 through the inner sidewall of the support airbag 310, which can enhance the support effect and improve the sealing performance of the support airbag 310; in addition, the other ends of the two sub-support ribs 311 can form a sealed cavity with the inner sidewall of the support airbag 310, which can further extend the heat conduction path, reduce the leakage of cold or heat in the box 200, thereby improving the thermal insulation quality of the box assembly 10, and can also reduce energy consumption in application scenarios that require energy-consuming thermal insulation.

[0030] In one embodiment, the support rib 311 includes a first segment and a second segment. The first segment is connected to the middle of the first airbag 312, and the second segment is connected to the first segment and divided into two support legs, so that the first segment and the second end are arranged in a "human" shape or an inverted "Y" shape.

[0031] In one embodiment, a second airbag 313 is also formed inside the supporting airbag 310, which is isolated from the first airbag 312. When the door 100 is in the closed state, the two sub-support ribs 311 and the second airbag 313 form a sealed cavity.

[0032] Understandably, in the arrangement direction X, a second airbag 313 is formed on the inner wall of the side of the supporting airbag 310 that abuts against the housing 200, and the second airbag 313 is arranged opposite to the first airbag 312. When the door 100 is in the open state, the two sub-support ribs 311 are located between the first airbag 312 and the second airbag 313; when the door 100 is in the closed state, the other ends of the two sub-support ribs 311 and the side of the second airbag 313 near the first airbag 312 form a sealed cavity. In this embodiment, the door seal 300 further forms a second airbag 313, which is opposite to the first airbag 312, inside the support airbag 310. When the door 100 is in the closed state, the support airbag 310 can form three support cavities in the arrangement direction X, which can further enhance the support function of the support airbag 310, prevent the support airbag 310 from undergoing severe deformation, and enable the support airbag 310 to fit tightly against the box 200 and the door 100, thereby enhancing the sealing performance of the box 200 and the door 100. In addition, multiple support cavities can also extend the heat conduction path, thereby reducing the leakage of cold or heat in the box 200, improving the thermal insulation quality of the box assembly 10, and reducing energy consumption in application scenarios that require energy-consuming thermal insulation.

[0033] In one embodiment, the door seal 300 further includes a first wing 330 and a second wing 340. The first wing 330 is connected to the outer wall of the support airbag 310 away from the latching member 320 and is located near the end of the support airbag 310 perpendicular to the arrangement direction X, or in the vertical direction Y. The first wing 330 is configured to abut against the outer side of the housing 200. The second wing 340 is connected to the other end of the support airbag 310 in the vertical direction Y and is configured to abut against the inner side of the housing 200. The inner side of the housing 200 refers to the side closest to the interior of the housing 200, and the outer side of the housing 200 refers to the side closest to the edge of the housing 200.

[0034] The door seal 300 of this embodiment, by setting a first wing 330 and a second wing 340, when the door 100 is in the closed state, the first wing 330 abuts against the outer side of the box 200 and is pressed and bent, while the second wing 340 abuts against the inner side of the box 200. At this time, the first wing 330 can enhance the fit between the door seal 300 and the outer side of the box 200, and the second wing 340 can enhance the fit between the door seal 300 and the inner side of the box 200. That is, the first wing 330 and the second wing 340 can ensure the fit between the box 200 and the door seal 300. In addition, the first wing 330 and the second wing 340 also extend the heat conduction path, which can reduce the leakage of cold or heat inside the box 200, thereby improving the insulation quality of the box assembly 10 and reducing energy consumption in application scenarios that require energy-consuming insulation.

[0035] In one embodiment, the second wing 340 is further provided with an auxiliary airbag, or the second wing 340 can be replaced by an auxiliary airbag. The auxiliary airbag provides secondary sealing for the gap between the supporting airbag 310 and the housing 200 and the door 100, thereby improving the sealing performance of the door seal 300. In addition, the auxiliary airbag can increase the contact area between the door 100 and the door seal 300, thereby reducing the leakage of cold or heat inside the housing 200 and enhancing the insulation effect. Furthermore, it can prevent the supporting airbag 310 from becoming loose due to aging after long-term use, and prevent gas from convection with the inside of the housing 200 through the gap of the door seal 300, thus ensuring the sealing performance.

[0036] In one embodiment, the door seal 300 further includes a third wing 350. The third wing 350 is connected to the outer wall of the support airbag 310 and is disposed on the same side as the latch 320. The third wing 350 is configured to abut against the door body 100. Specifically, the third wing 350 is disposed at one end of the support airbag 310 near the outside of the door body 100 in the direction perpendicular to the arrangement direction X or in the direction perpendicular to the direction Y, and the third wing 350 extends toward the side away from the support airbag 310, thereby abutting against the door body 100.

[0037] In this embodiment, the door seal 300 abuts against the door 100 by setting a third wing 350, ensuring that when the door 100 is in the closed state, the outer peripheral sidewall of the door 100 can be covered by the third wing 350, thereby increasing the heat conduction path of the door seal 300, reducing the leakage of cold or heat inside the enclosure 200, and thus improving the thermal insulation quality of the enclosure assembly 10. In application scenarios that require energy-consuming thermal insulation, it can also reduce energy consumption. In addition, the outer peripheral sidewall of the door 100 can be covered by the third wing 350, which also achieves an aesthetic effect.

[0038] In one embodiment, the fastener 320 includes a vertical airbag 321 and limiting inverted wings 322. Specifically, the interior of the fastener 320 is hollow to form the vertical airbag 321, and limiting inverted wings 322 are symmetrically arranged on the outer wall of the end of the vertical airbag 321 opposite to the supporting airbag 310 in the X-direction. The vertical airbag 321 is configured to engage with the slot of the door body 100, realizing a detachable connection with the door body 100. The limiting inverted wings 322 are configured to abut against the inner wall of the slot of the door body 100, increasing the difficulty of the vertical airbag 321 detaching from the slot and enhancing the connection stability between the vertical airbag 321 and the door body 100.

[0039] In one embodiment, the fastener 320 further includes an engaging wing 323, which is connected to the end of the limiting wing 322 facing away from the supporting airbag 310. The engaging wing 323 is configured to abut against the bottom wall of the slot in the door 100. The engaging wing 323 does not affect the size of the slot or the assembly of the vertical airbag 321 with the slot, and can further prevent cold air leakage, effectively preventing cold air from leaking outward along the slot to the outside of the door 100.

[0040] In one embodiment, the vertical airbag 321 has ribs inside, with both ends of the ribs connected to the sidewalls of the vertical airbag 321 extending along the arrangement direction X. The middle portion of the rib has a corner facing the end of the vertical airbag 321. The fastener 320 of this embodiment, by providing ribs inside the vertical airbag 321, can control the vertical airbag 321 to quickly return to its original shape when compressed; and can control the deformation of the vertical airbag 321 and its rapid return to its original shape when stretched.

[0041] This application provides a cabinet assembly 10, which includes a door 100, a cabinet 200, and a door seal 300. The cabinet 200 has a storage cavity and an opening 210 communicating with the storage cavity. The door 100 is connected to the cabinet 200 and is configured to either close or open the opening 210. The door seal 300 is connected to the door 100, and when the door 100 is closed, the door seal 300 is located between the cabinet 200 and the door 100. When the door 100 is closed, the distance between the outer peripheral sidewall of the door 100 facing the cabinet 200 and the cabinet 200 is 6mm to 7mm, for example, the distance between the outer peripheral sidewall of the door 100 facing the cabinet 200 and the cabinet 200 is 6mm, 6.5mm, 6.8mm, 6.9mm, 7mm, etc. This design can increase the storage capacity of the enclosure 200 without changing the volume of the enclosure assembly, or reduce the volume of the enclosure assembly 10 without changing the storage capacity. The door seal 300 can be any one of the door seals 300 described in the above embodiments, and is not limited thereto.

[0042] The enclosure assembly 10 can be a device with heat preservation function, or can be applied to a device with heat preservation function. For example, the enclosure assembly 10 can be a portable insulated box, or the enclosure assembly 10 can be applied to a refrigerator, or the enclosure assembly 10 can be applied to a device with both heating and heat preservation functions. There are no restrictions on the type or application scenario of the enclosure assembly 10.
