Description

Technical Field

[0001] Some embodiments of this application relate to household appliance technology. In particular, they relate to a refrigerator. Background Technology

[0002] In the refrigerator manufacturing industry, the refrigerator door is one of the core components, and its structural design directly affects the product's sealing performance, heat insulation effect, and appearance quality. Traditional refrigerator doors are usually composed of a door shell made of metal or plastic, end caps, an inner liner, and a polyurethane foam filling layer. Among these, the assembly process of the door shell and end caps is a key step in ensuring the structural integrity of the door and the quality of the foaming.

[0003] Currently, the industry commonly uses temporary fixation with tape to pre-assemble the door shell and end cap. Although this technology has the advantages of being easy to operate and low in cost, the tape has low bonding strength. Therefore, the lateral stress generated by the expansion of polyurethane during the foaming process far exceeds the tape's bearing capacity, which will cause the tape bonding interface to detach, thereby increasing the risk of foam leakage in the door. Summary of the Invention

[0004] Some embodiments of this application provide a refrigerator to reduce the risk of door leakage.

[0005] To achieve the above objectives, some embodiments of this application provide a refrigerator comprising:

[0006] The box body has a storage room inside, and the box body has an opening communicating with the storage room;

[0007] A door body, rotatably connected to the housing to close or open the opening, the door body comprising:

[0008] A door shell, the door shell having a top end and a bottom end, the door shell comprising:

[0009] A front panel, the front panel having opposing first and second side edges along the width direction of the door body;

[0010] A first sidewall, the first sidewall being connected to the first side edge;

[0011] The second sidewall is opposite to the first sidewall and is connected to the second side edge;

[0012] The inner liner is connected to the door shell;

[0013] A first end cap, the first end cap comprising:

[0014] A first cover portion, which covers the top of the door shell;

[0015] A first extension extends toward the bottom end and fits against the inner surfaces of the first sidewall and the second sidewall;

[0016] The second end cap is disposed at the bottom end of the door shell. The second end cap, the first end cap, the door shell, and the inner liner form a foaming cavity, which is filled with a foaming layer.

[0017] The door shell also includes:

[0018] A first bending limiting structure is disposed at the edge of the first sidewall and / or the second sidewall away from the front panel. The first bending limiting structure bends toward the foaming cavity and abuts against the edge of the first extension, so that the first extension is engaged between the first sidewall and the first bending limiting structure, and / or the first extension is engaged between the second sidewall and the first bending limiting structure, thereby preventing the first sidewall and / or the second sidewall from loosening relative to the first extension in a direction away from the foaming cavity.

[0019] The first bending limiting structure bends towards the foaming cavity and abuts against the edge of the first extension. The first extension is engaged between the first sidewall and the first bending limiting structure. The first bending limiting structure can restrict the freedom of the first sidewall to detach from the first extension in the direction away from the foaming cavity, thereby fixing the first sidewall relative to the first extension. In other words, the first bending limiting structure can prevent the first sidewall from turning outward relative to the first extension, thereby ensuring the fit between the first sidewall and the first extension. This avoids leakage of the door body when foaming in the foaming cavity and improves the aesthetics of the door body.

[0020] Similarly, when the first bending limiting structure is set on the second side wall, it can prevent the second side wall from loosening relative to the first extension in the direction away from the foaming cavity, thereby fixing the second side wall relative to the first extension. In other words, the first bending limiting structure can prevent the second side wall from turning outward relative to the first extension, thereby ensuring the fit between the second side wall and the first extension, further avoiding the occurrence of door leakage, and improving the aesthetics of the door.

[0021] Some embodiments of this application also provide a refrigerator, which includes:

[0022] The box body has a storage room inside, and the box body has an opening communicating with the storage room;

[0023] A door body, rotatably connected to the housing to close or open the opening, the door body comprising:

[0024] A door shell, the door shell having a top end and a bottom end, the door shell comprising:

[0025] A front panel, the front panel having opposing first and second side edges along the width direction of the door body;

[0026] A first sidewall, the first sidewall being connected to the first side edge;

[0027] The second sidewall is opposite to the first sidewall and is connected to the second side edge;

[0028] The inner liner is connected to the door shell;

[0029] A first end cap is disposed at the top of the door housing;

[0030] A second end cap, the second end cap, the first end cap, the door shell, and the inner liner form a foaming cavity, the foaming cavity being filled with a foaming layer, the second end cap comprising:

[0031] The second cover portion is fitted onto the bottom end of the door shell;

[0032] The second extension extends toward the foaming cavity and fits against the inner surface of the first sidewall and / or the second sidewall;

[0033] The door shell also includes:

[0034] A second bending limiting structure is disposed on the edge of the first sidewall and / or the second sidewall away from the front panel. The second bending limiting structure bends toward the foaming cavity and abuts against the edge of the second extension, so that the second extension is engaged between the first sidewall and the second bending limiting structure, and / or the second extension is engaged between the second sidewall and the second bending limiting structure, thereby preventing the first sidewall and / or the second sidewall from loosening relative to the second extension in a direction away from the foaming cavity.

[0035] Therefore, by bending the second bending limiting structure towards the foaming cavity and abutting the edge of the second extension, and with the second extension being engaged between the first sidewall and the second bending limiting structure, the second bending limiting structure can restrict the degree of freedom of the first sidewall to detach from the second extension in the direction away from the foaming cavity, thereby fixing the first sidewall relative to the second extension. In other words, the second bending limiting structure can prevent the first sidewall from turning outward relative to the second extension, thus ensuring the fit between the first sidewall and the second extension, thereby avoiding the leakage of the door body when foaming in the foaming cavity, and improving the aesthetics of the door body.

[0036] Similarly, when the second bending limiting structure is installed on the second side wall, it can prevent the second side wall from loosening relative to the second extension in the direction away from the foaming cavity, thereby fixing the second side wall relative to the second extension. In other words, the second bending limiting structure can prevent the second side wall from turning outward relative to the second extension, thereby ensuring the fit between the second side wall and the second extension, further avoiding the occurrence of door leakage, and improving the aesthetics of the door.

[0037] In some possible embodiments, the door housing further includes:

[0038] The first bent sidewall is opposite to the front panel and connected to the edge of the first sidewall away from the front panel. The first bent sidewall is also connected to the inner liner.

[0039] The second bent sidewall is opposite to the front panel and connected to the edge of the second sidewall away from the front panel. The second bent sidewall is also connected to the inner liner.

[0040] The first bending limiting structure is connected to the edge of the first bending sidewall away from the first sidewall, and / or the first bending limiting structure is connected to the edge of the second bending sidewall away from the first sidewall.

[0041] By setting the first bent sidewall and the second bent sidewall, the contact area between the sidewall of the door shell and the first extension is increased, thereby improving the stability and reliability of the connection between the first end cover and the door shell.

[0042] In addition, by making the first bent sidewall face the front panel and also connecting the first bent sidewall to the inner liner, the contact area between the door shell and the inner liner can be increased, thereby improving the reliability of the connection between the door shell and the inner liner.

[0043] Similarly, by making the second bent sidewall face the front panel and also connecting the second bent sidewall to the inner liner, the contact area between the door shell and the inner liner can be increased, thereby improving the reliability of the connection between the door shell and the inner liner.

[0044] In some possible embodiments, the first bending limiting structure includes:

[0045] The first sub-limiting structure is connected to the edge of the first bent sidewall away from the first sidewall, and the first sub-limiting structure bends toward the foaming cavity and abuts against one side edge of the first extension.

[0046] The second sub-limiting structure is connected to the edge of the second bent sidewall away from the first sidewall, and the second sub-limiting structure bends toward the foaming cavity and abuts against the other edge of the first extension.

[0047] Therefore, by bending the first sub-limiting structure toward the foaming cavity and abutting against one side edge of the first extension, the first sidewall can be limited along its thickness direction, thereby preventing the first sidewall from springing away from the foaming cavity relative to the first extension. Similarly, by bending the second sub-limiting structure toward the foaming cavity and abutting against the other side edge of the first extension, the second sidewall can be limited along its thickness direction, thereby preventing the second sidewall from springing away from the foaming cavity relative to the first extension. This ensures the fit between the first and second sidewalls and the first extension, avoiding bubble leakage between the first sidewall and the first extension, as well as between the second sidewall and the first extension.

[0048] In addition, since both the first sub-limiting structure and the second sub-limiting structure abut against the first extension after bending, the first limiting structure and the second sub-limiting structure can limit the first sidewall and the second sidewall near the first end cap.

[0049] In some possible embodiments, the distance between the first bending limiting structure and the top of the door shell is a, where 6mm ≤ a ≤ 15mm.

[0050] The distance between the first bending limiting structure and the top of the door shell is between 6mm and 15mm. This avoids interference between the first bending limiting structure and the first end cap when the first bending limiting structure bends toward the foaming cavity, and also ensures the stability of the connection between the first bending limiting structure and the first extension, thereby ensuring the reliability of the first bending limiting structure in limiting the first side wall.

[0051] In some possible embodiments, the first bending limiting structure includes:

[0052] A limiting part, one end of which is connected to the first bent sidewall and / or the second bent sidewall, the limiting part bends toward the foaming cavity and abuts against the edge of the first extension;

[0053] The pressing part is connected to the other end of the limiting part, and the area of ​​the pressing part is larger than the area of ​​the limiting part.

[0054] Since the area of ​​the pressing part is larger than the area of ​​the limiting part, when the first end cap is assembled onto the door shell, it is easy for the worker to press it so that the limiting part bends toward the foaming cavity.

[0055] In some possible embodiments, both the limiting part and the pressing part are elongated structures, with an angle between the length direction of the limiting part and the length direction of the pressing part, and the length of the limiting part is less than the length of the pressing part.

[0056] Since the length of the limiting part is less than the length of the pressing part, the contact area between the operator and the first bending limiting structure can be increased when the first bending limiting structure is pressed, thereby facilitating the bending of the limiting part toward the foaming cavity.

[0057] In some possible embodiments, the limiting portion is connected to the end of the pressing portion, or the limiting portion is connected to the middle portion of the pressing portion.

[0058] This simplifies the design of the first bending limiting structure.

[0059] In some possible embodiments, when the limiting part is connected to the first bent sidewall, the distance between the pressing part and the first bent sidewall is b, 2mm≤b≤8mm, and / or the width of the limiting part is d, 3mm≤d≤12mm.

[0060] This ensures that the distance between the pressing part and the first bent sidewall is between 2mm and 8mm, which can reduce material waste while ensuring the limiting of the first sidewall and / or the second sidewall.

[0061] The width of the limiting part is made to be between 3mm and 12mm. In this way, the operation difficulty of bending and limiting can be reduced, while ensuring the reliability of the limiting part in limiting the first side wall and / or the second side wall after bending.

[0062] In some possible embodiments, the first sub-limiting structure is integrally formed with the first bent sidewall, and the second sub-limiting structure is integrally formed with the second bent sidewall.

[0063] By integrally forming the first sub-limiting structure with the first bent sidewall and the second sub-limiting structure with the second bent sidewall, the number of door components can be reduced, thereby simplifying the door assembly process.

[0064] Compared with the prior art, the beneficial effects of this application are as follows:

[0065] The first bending limiting structure bends towards the foaming cavity and abuts against the edge of the first extension. The first extension is engaged between the first sidewall and the first bending limiting structure. The first bending limiting structure can restrict the freedom of the first sidewall to detach from the first extension in the direction away from the foaming cavity, thereby fixing the first sidewall relative to the first extension. In other words, the first bending limiting structure can prevent the first sidewall from turning outward relative to the first extension, thereby ensuring the fit between the first sidewall and the first extension. This avoids leakage of the door body when foaming in the foaming cavity and improves the aesthetics of the door body.

[0066] Similarly, when the first bending limiting structure is set on the second side wall, it can prevent the second side wall from loosening relative to the first extension in the direction away from the foaming cavity, thereby fixing the second side wall relative to the first extension. In other words, the first bending limiting structure can prevent the second side wall from turning outward relative to the first extension, thereby ensuring the fit between the second side wall and the first extension, further avoiding the occurrence of door leakage, and improving the aesthetics of the door.

Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0087] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0088] As described in the background section, in the refrigerator manufacturing industry, the refrigerator door is one of the core components, and its structural design directly affects the product's sealing performance, heat insulation effect, and appearance quality. Traditional refrigerator doors are usually composed of a door shell made of metal or plastic, end caps, an inner liner, and a polyurethane foam filling layer. Among these, the assembly process of the door shell and end caps is a key step in ensuring the structural integrity of the door and the quality of the foaming.

[0089] Currently, the industry commonly uses temporary fixation with tape to pre-assemble the door shell and end cap. Although this technology has the advantages of being easy to operate and low in cost, the tape has low bonding strength. Therefore, the lateral stress generated by the expansion of polyurethane during the foaming process far exceeds the tape's bearing capacity, which will cause the tape bonding interface to detach, thereby increasing the risk of foam leakage in the door shell.

[0090] In related technologies, a snap-fit ​​structure (i.e., snap-fit ​​hole and snap-fit) is set at the connection between the door shell and the end cap. Specifically, a snap-fit ​​is set on the surface of the end cap that fits against the side wall of the door shell, and a snap-fit ​​hole is set on the side wall of the door shell. However, when foaming occurs in the foaming cavity, the lateral stress generated by the expansion of polyurethane can push the side wall of the door shell to tend to fold outward, thereby causing the snap-fit ​​to detach from the snap-fit ​​hole, resulting in leakage holes and foam leakage.

[0091] The researchers in this application conducted a detailed study on the end cap and the door shell, and sorted out the necessity of sealing the assembly of the door shell and the end cap. They found that setting a limiting structure between the door shell and the end cap would easily affect the sealing performance of the assembly between the door shell and the end cap. Therefore, it is not possible to set a limiting structure between the door shell and the end cap to restrict the outward folding of the side wall of the door shell. Based on this, considering that the door shell, the end cap and the inner liner of the door body form a foam cavity, a limiting structure can be set in the foam cavity. So, should it be set on the end cap or the door shell?

[0092] Typically, the side of the end cap is inserted into the door shell. Considering the assembly and sealing between the door shell and the door liner, the structure that restricts the door shell from turning outward can only be set on the door shell. This prevents the side wall of the door shell from turning outward, thereby reducing the risk of leakage in the door.

[0093] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0094] The refrigerator 100 provided in this application can have various implementation forms, such as a double-door refrigerator 100, a single-door refrigerator 100, etc. Figure 1 This is a specific implementation of a refrigerator according to an embodiment of this application.

[0095] Figure 2 An exploded view of the door 120 provided in an embodiment of this application. Figure 3 An assembly drawing of the door 120 provided in an embodiment of this application.

[0096] In one possible embodiment, see Figure 1 The refrigerator 100 includes a cabinet 110, a storage compartment is formed inside the cabinet 110, and an opening communicating with the storage compartment is formed on the cabinet 110.

[0097] The storage room includes a refrigerator compartment and a freezer compartment, which are independent of each other. The temperature in the refrigerator compartment is higher than the temperature in the freezer compartment. For example, the freezer compartment is located below the refrigerator compartment. The refrigerator compartment is provided with at least one refrigerator partition to divide the refrigerator compartment into multiple refrigerator storage spaces. A refrigerator drawer is provided in at least one refrigerator storage space to facilitate the user's access to refrigerated items. Similarly, the freezer compartment is provided with at least one freezer partition to divide the freezer compartment into multiple freezer storage spaces. A freezer drawer is provided in at least one freezer storage space to store frozen items for the user's access.

[0098] Furthermore, the openings connected to the storage room include a freezer opening and a refrigerator opening. The freezer opening is connected to the freezer compartment, and the refrigerator opening is connected to the refrigerator compartment. However, the freezer opening and the refrigerator opening are not connected to each other, so as to avoid the temperature inside the freezer compartment affecting the temperature inside the refrigerator compartment, thereby ensuring the freezing effect of the freezer compartment and the refrigeration effect of the refrigerator compartment.

[0099] In addition, there are no restrictions on the shape and size of the box 110. As shown in the figure, the box 110 is a cuboid box 110.

[0100] In addition, the refrigeration modes of the refrigerator 100 include, but are not limited to, direct cooling, air cooling, and hybrid cooling (direct cooling and air cooling). This embodiment mainly uses air cooling as an example for illustration. Optionally, the refrigerator 100 is equipped with a refrigeration system and an air duct system. The refrigeration system is used to generate cold air, and the air duct system can transport the cold air generated by the refrigeration system to the refrigerator compartment and the freezer compartment of the refrigerator 100 to achieve the purpose of refrigeration in the refrigerator compartment and freezing in the freezer compartment.

[0101] A refrigeration system typically refers to a closed system consisting of components such as a compressor, evaporator, condenser, dryer filter, return gas pipe, and throttling device, as well as refrigerant. Each component is distributed in different locations within the refrigerator 100 according to its structural characteristics to meet the requirements of its corresponding function.

[0102] The working process of a refrigeration system mainly includes compression, condensation, throttling, and evaporation.

[0103] The compression process is as follows: After plugging in the power cord of the refrigerator 100, the compressor starts to work when the contacts of the thermostat are closed. The low-temperature and low-pressure refrigerant from the evaporator is drawn into the compressor and compressed into a high-temperature and high-pressure refrigerant gas by the compressor before being discharged into the condenser.

[0104] The condensation process is as follows: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and it is gradually cooled into room-temperature and high-pressure refrigerant saturated vapor, and then cooled into refrigerant saturated liquid.

[0105] The throttling process is as follows: the condensed saturated liquid refrigerant is filtered through a dryer to remove moisture and impurities before flowing into the throttling device. The throttling device reduces the pressure and turns the refrigerant into a low-pressure, room-temperature wet vapor.

[0106] Evaporation process: Room temperature and low pressure wet vapor enters the evaporator, begins to absorb heat and vaporize, lowers the temperature of the evaporator and its surroundings, achieves refrigeration, and also turns the refrigerant into a low temperature and low pressure gas.

[0107] The refrigerant that comes out of the evaporator returns to the compressor and repeats the above process. Energy is converted through the change in the state of the refrigerant, and the heat inside the refrigerator 100 is transferred to the outside air, thereby realizing the refrigeration cycle of the refrigerator 100.

[0108] The air duct system is installed inside the refrigerator 100 to provide power for the flow of cold air. The air duct system generally includes a fan and air ducts.

[0109] In some possible embodiments, see Figure 1 , Figure 2 and Figure 3 The refrigerator 100 also includes a door 120, which is rotatably connected to the cabinet 110 to open or close the opening.

[0110] The door 120 includes a refrigerator door and a freezer door. The refrigerator door is used to open or close the refrigerator opening, and the freezer door is used to open or close the freezer opening.

[0111] When a user needs to take out or put in refrigerated items, the refrigerator door should first be rotated away from the refrigerator opening to open it. After taking out or putting in the refrigerated items, the door should be rotated towards the refrigerator opening to close it.

[0112] The opening and closing of the freezer opening is the same as that of the refrigerator opening, and will not be repeated here.

[0113] In some possible embodiments, see Figure 2 and Figure 3 The door body 120 includes a door shell 121, an inner liner 122, a first end cap 123, and a second end cap 124. The door shell 121 has a top end and a bottom end. The first end cap 123 is disposed at the top end of the door shell 121. The inner liner 122 is connected to the door shell 121. The second end cap 124 is disposed at the bottom end of the door shell 121. The second end cap 124, the first end cap 123, the door shell 121, and the inner liner 122 form a foaming cavity, which is used to fill a foaming layer.

[0114] The structures of the first end cap 123 and the second end cap 124 can be the same or different. Those skilled in the art can design according to the actual situation. For example, if the door 120 is the door of the freezer compartment, a concealed pull handle is usually provided on the first end cap 123 of the door 120. In this way, the structures of the first end cap 123 and the second end cap 124 are different.

[0115] The inner liner 122 is equipped with a mounting section for mounting shelves, which are used to store items.

[0116] The function of the foam layer is to insulate against heat exchange, that is, to prevent the cold air inside the refrigerator 100 from being transferred to the outside of the refrigerator 100, and similarly to prevent the heat outside from being transferred to the inside of the refrigerator 100. This ensures the freezing effect of the refrigerator 100 and reduces the risk of condensation on the door 120.

[0117] In some possible embodiments, see Figure 2 The door shell 121 includes a front panel 1211, a first side wall 1212 and a second side wall 1213. The front panel 1211 has a first side edge and a second side edge opposite to each other along the width direction of the door body 120. The first side wall 1212 is connected to the first side edge. The second side wall 1213 is opposite to the first side wall 1212 and is connected to the second side edge.

[0118] Wherein, the width direction of the door body 120 refers to the direction perpendicular to the height of the door body 120 (i.e., Figure 2 The direction indicated by the Z-arrow in the middle) and the direction of the thickness direction (i.e. Figure 2 (The direction indicated by the Y-arrow in the middle), that is... Figure 2 The direction indicated by the X arrow.

[0119] The aforementioned front panel 1211 refers to the surface of the door shell 121 that faces the opening.

[0120] The first sidewall 1212 is perpendicular to or approximately perpendicular to the front panel 1211, the second sidewall 1213 is perpendicular to or approximately perpendicular to the front panel 1211, and the first sidewall 1212 and the second sidewall 1213 are parallel to or approximately parallel to each other.

[0121] The thickness of the door body 120 and the foaming cavity can be determined by connecting the first side wall 1212 to the first side edge and the second side wall 1213 to the second side edge.

[0122] See some possible embodiments. Figure 2 , Figure 4 The first end cap 123 includes a first cover portion 1231 and a first extension portion 1232. The first cover portion 1231 covers the top of the door shell 121; the first extension portion 1232 extends toward the bottom and fits against the inner surfaces of the first side wall 1212 and the second side wall 1213.

[0123] Since the first extension 1232 extends toward the bottom and fits against the inner surfaces of the first sidewall 1212 and the second sidewall 1213, the contact area between the first end cover 123 and the door shell 121 can be increased, thereby improving the stability of the connection between the first end cover 123 and the door shell 121.

[0124] In some possible embodiments, see Figure 4 and Figure 5The door shell 121 also includes a first bending limiting structure 125, which is disposed at the edge of the first side wall 1212 and / or the second side wall 1213 away from the front panel 1211. The first bending limiting structure 125 bends toward the foaming cavity and abuts against the edge of the first extension 1232, so that the first extension 1232 is engaged between the first side wall 1212 and the first bending limiting structure 125, and / or the first extension 1232 is engaged between the second side wall 1213 and the first bending limiting structure 125, thereby preventing the first side wall 1212 and / or the second side wall 1213 from loosening relative to the first extension 1232 in the direction away from the foaming cavity.

[0125] The first bending limiting structure 125 is disposed at the edge of the first sidewall 1212 and / or the second sidewall 1213 away from the front panel 1211. It should be understood that the first bending limiting structure 125 is disposed at the edge of the first sidewall 1212 away from the front panel 1211, or the first bending limiting structure 125 is disposed at the edge of the second sidewall 1213 away from the front panel 1211, or the first bending limiting structure 125 is disposed at the edges of the first sidewall 1212 and the second sidewall 1213 away from the front panel 1211.

[0126] When the first bending limiting structure 125 is disposed at the edge of the first sidewall 1212 away from the front panel 1211, the first extension 1232 of the end cap first extends into the door shell 121 and fits against the first sidewall 1212 and the second sidewall 1213. Then, the first bending limiting structure 125 is manually bent so that it bends towards the foaming cavity and abuts against the edge of the first extension 1232. Figure 5 As shown, the first extension 1232 will be engaged between the first sidewall 1212 and the first bending limiting structure 125. The first sidewall 1212 and the first bending limiting structure 125 can limit the first extension 1232 along their thickness direction. Similarly, since the first bending limiting structure 125 abuts against the edge of the first extension 1232, the first extension 1232 can limit the first sidewall 1212 along the thickness direction of the first sidewall 1212 to prevent the first sidewall 1212 from loosening relative to the first extension 1232 in a direction away from the foaming cavity.

[0127] Therefore, by bending the first bending limiting structure 125 toward the foaming cavity and abutting the edge of the first extension 1232, and with the first extension 1232 being engaged between the first sidewall 1212 and the first bending limiting structure 125, the first bending limiting structure 125 can restrict the degree of freedom of the first sidewall 1212 to detach from the first extension 1232 in a direction away from the foaming cavity, thereby fixing the first sidewall 1212 relative to the first extension 1232. In other words, the first bending limiting structure 125 can prevent the first sidewall 1212 from turning outward relative to the first extension 1232, thereby ensuring the fit between the first sidewall 1212 and the first extension 1232, thus avoiding the leakage of the door body 120 when foaming in the foaming cavity, and improving the aesthetics of the door body 120.

[0128] Similarly, when the first bending limiting structure 125 is disposed on the second side wall 1213, it can prevent the second side wall 1213 from loosening relative to the first extension 1232 in the direction away from the foaming cavity, thereby fixing the second side wall 1213 relative to the first extension 1232. In other words, the first bending limiting structure 125 can prevent the second side wall 1213 from turning outward relative to the first extension 1232, thereby ensuring the fit between the second side wall 1213 and the first extension 1232, further avoiding the occurrence of foam leakage in the door body 120, and improving the aesthetics of the door body 120.

[0129] In some other possible embodiments, see Figure 2 and Figure 4 The second end cap 124 includes a second cover portion 1241 and a second extension portion 1242. The second cover portion 1241 covers the bottom end of the door shell 121. The second extension portion 1242 extends toward the foaming cavity and fits against the inner surface of the first sidewall 1212 and / or the second sidewall 1213.

[0130] Since the second extension 1242 extends toward the foaming cavity and fits against the inner surfaces of the first sidewall 1212 and the second sidewall 1213, the contact area between the second end cap 124 and the door shell 121 can be increased, thereby improving the stability of the connection between the second end cap 124 and the door shell 121.

[0131] In some other possible embodiments, see Figure 2 and Figure 4The door shell 121 also includes a second bending limiting structure 126, which is disposed at the edge of the first side wall 1212 and / or the second side wall 1213 away from the front panel 1211. The second bending limiting structure 126 bends toward the foaming cavity and abuts against the edge of the second extension 1242, so that the second extension 1242 is engaged between the first side wall 1212 and the second bending limiting structure 126, and / or the second extension 1242 is engaged between the second side wall 1213 and the second bending limiting structure 126, thereby preventing the first side wall 1212 and / or the second side wall 1213 from loosening relative to the second extension 1242 in the direction away from the foaming cavity.

[0132] The second bending limiting structure 126 is disposed at the edge of the first sidewall 1212 and / or the second sidewall 1213 away from the front panel 1211. It should be understood that the second bending limiting structure 126 is disposed at the edge of the first sidewall 1212 away from the front panel 1211, or the second bending limiting structure 126 is disposed at the edge of the second sidewall 1213 away from the front panel 1211, or the second bending limiting structure 126 is disposed at the edges of the first sidewall 1212 and the second sidewall 1213 away from the front panel 1211.

[0133] When the second bending limiting structure 126 is disposed at the edge of the first sidewall 1212 away from the front panel 1211, the second extension 1242 of the end cap first extends into the door shell 121 and fits against the first sidewall 1212 and the second sidewall 1213. Then, the second bending limiting structure 126 is manually bent so that it bends towards the foaming cavity and abuts against the edge of the second extension 1242. In this way, the second extension 1242 will be locked onto the first sidewall 121. 2. Between the first sidewall 1212 and the second bending limiting structure 126, the first sidewall 1212 and the second bending limiting structure 126 can limit the second extension 1242 along their thickness direction. Similarly, since the second bending limiting structure 126 abuts against the edge of the second extension 1242, the second extension 1242 can limit the first sidewall 1212 along the thickness direction of the first sidewall 1212 to prevent the first sidewall 1212 from loosening relative to the second extension 1242 in a direction away from the foaming cavity.

[0134] Therefore, by bending the second bending limiting structure 126 toward the foaming cavity and abutting the edge of the second extension 1242, and with the second extension 1242 being engaged between the first sidewall 1212 and the second bending limiting structure 126, the second bending limiting structure 126 can restrict the degree of freedom of the first sidewall 1212 to detach from the second extension 1242 in a direction away from the foaming cavity, thereby fixing the first sidewall 1212 relative to the second extension 1242. In other words, the second bending limiting structure 126 can prevent the first sidewall 1212 from turning outward relative to the second extension 1242, thereby ensuring the fit between the first sidewall 1212 and the second extension 1242, thus avoiding the leakage of the door body 120 when foaming in the foaming cavity, and improving the aesthetics of the door body 120.

[0135] Similarly, when the second bending limiting structure 126 is disposed on the second side wall 1213, it can prevent the second side wall 1213 from loosening relative to the second extension 1242 in the direction away from the foaming cavity, thereby fixing the second side wall 1213 relative to the second extension 1242. In other words, the second bending limiting structure 126 can prevent the second side wall 1213 from turning outward relative to the second extension 1242, thereby ensuring the fit between the second side wall 1213 and the second extension 1242, further avoiding the occurrence of foam leakage in the door body 120, and improving the aesthetics of the door body 120.

[0136] In some possible embodiments, see Figure 5 and Figure 6 The door shell 121 also includes a first bent sidewall 1214 and a second bent sidewall 1215. The first bent sidewall 1214 is opposite to the front panel 1211 and connected to the edge of the first sidewall 1212 away from the front panel 1211. The first bent sidewall 1214 is also connected to the inner liner 122. The second bent sidewall 1215 is opposite to the front panel 1211 and connected to the edge of the second sidewall 1213 away from the front panel 1211. The first bent sidewall 1214 is also connected to the inner liner 122. A first bending limiting structure 125 is connected to the edge of the first bent sidewall 1214 away from the first sidewall 1212, and / or, the first bending limiting structure 125 is connected to the edge of the second bent sidewall 1215 away from the first sidewall 1212.

[0137] By setting the first bent sidewall 1214 and the second bent sidewall 1215, the contact area between the sidewall of the door shell 121 and the first extension 1232 is increased, thereby improving the stability and reliability of the connection between the first end cover 123 and the door shell 121.

[0138] In addition, by making the first bent sidewall 1214 face the front panel 1211 and the first bent sidewall 1214 is also connected to the inner liner 122, the contact area between the door shell 121 and the inner liner 122 can be increased, thereby improving the reliability of the connection between the door shell 121 and the inner liner 122.

[0139] Similarly, by making the second bent sidewall 1215 opposite to the front panel 1211, and by connecting the second bent sidewall 1215 to the inner liner 122, the contact area between the door shell 121 and the inner liner 122 can be increased, thereby improving the reliability of the connection between the door shell 121 and the inner liner 122.

[0140] Furthermore, by connecting the first bending limiting structure 125 to the edge of the first bending sidewall 1214 away from the first sidewall 1212, and / or by connecting the first bending limiting structure 125 to the edge of the second bending sidewall 1215 away from the first sidewall 1212, the first bending limiting structure 125 can be connected to the first sidewall 1212 through the first bending sidewall 1214, and the second bending limiting structure 126 can be connected to the second sidewall 1213 through the second bending sidewall 1215, thereby improving the reliability of the first bending limiting structure 125.

[0141] In some possible embodiments, see Figure 4 and Figure 6 The first bending limiting structure 125 includes a first sub-limiting structure 1251 and a second sub-limiting structure 1252. The first sub-limiting structure 1251 is connected to the edge of the first bending sidewall 1214 away from the first sidewall 1212. The first sub-limiting structure 1251 bends toward the foaming cavity and abuts against one side edge of the first extension 1232. The second sub-limiting structure 1252 is connected to the edge of the second bending sidewall 1215 away from the first sidewall 1212. The second sub-limiting structure 1252 bends toward the foaming cavity and abuts against the other side edge of the first extension 1232.

[0142] Therefore, by bending the first sub-limiting structure 1251 toward the foaming cavity and abutting against one side edge of the first extension 1232, the first sidewall 1212 can be limited along its thickness direction, thereby preventing the first sidewall 1212 from springing away from the foaming cavity relative to the first extension 1232. Similarly, by bending the second sub-limiting structure 1252 toward the foaming cavity and abutting against the other side edge of the first extension 1232, the second sidewall 1213 can be limited along its thickness direction, thereby preventing the second sidewall 1213 from springing away from the foaming cavity relative to the first extension 1232. This ensures the fit between the first sidewall 1212 and the second sidewall 1213 and the first extension 1232, avoiding bubble leakage between the first sidewall 1212 and the first extension 1232, as well as between the second sidewall 1213 and the first extension 1232.

[0143] In addition, since the first sub-limiting structure 1251 and the second sub-limiting structure 1252 both abut against the first extension 1232 after bending, the first limiting structure and the second sub-limiting structure 1252 can limit the first sidewall 1212 and the second sidewall 1213 near the first end cap 123.

[0144] Similarly, the second bending limiting structure 126 includes a third sub-limiting structure 1261 and a fourth sub-limiting structure 1262. The third sub-limiting structure 1261 is connected to the edge of the first bending sidewall 1214 away from the first sidewall 1212. The third sub-limiting structure 1261 bends toward the foaming cavity and abuts against one side edge of the second extension 1242. The fourth sub-limiting structure 1262 is connected to the edge of the second bending sidewall 1215 away from the first sidewall 1212. The fourth sub-limiting structure 1262 bends toward the foaming cavity and abuts against the other side edge of the second extension 1242. This ensures the fit between the first sidewall 1212 and the second sidewall 1213 and the second extension 1242, respectively, and avoids leakage between the first sidewall 1212 and the second extension 1242, as well as between the second sidewall 1213 and the second extension 1242.

[0145] Furthermore, since the third sub-limiting structure 1261 and the fourth sub-limiting structure 1262 both abut against the second extension 1242 after bending, the third limiting structure and the fourth sub-limiting structure 1262 can limit the first sidewall 1212 and the second sidewall 1213 near the second end cap 124.

[0146] In some possible embodiments, see Figure 7 The distance between the first bending limiting structure 125 and the top of the door shell 121 is a, 6mm≤a≤15mm.

[0147] If the distance between the first bending limiting structure 125 and the top of the door shell 121 is less than 6mm, when the first bending limiting structure 125 bends towards the foaming cavity, it is very easy for interference to occur between the first bending limiting structure 125 and the first end cap 123, thereby affecting the limiting effect of the first bending limiting structure 125 on the first side wall 1212. If the distance between the first bending limiting structure 125 and the top of the door shell 121 is greater than 15mm, then after the first bending limiting structure 125 bends towards the foaming cavity, it is very likely that it will not be able to abut against the first extension 1232, or the first bending limiting structure 125 and the first extension 1212 will not be able to abut against each other. The edge 32 faces the bottom, thus affecting the reliability of the connection between the first bending limiting structure 125 and the first extension 1232, and consequently affecting the reliability of limiting the first sidewall 1212. Based on this, the distance between the first bending limiting structure 125 and the top of the door shell 121 is between 6mm and 15mm. In this way, interference between the first bending limiting structure 125 and the first end cap 123 can be avoided when the first bending limiting structure 125 bends towards the foaming cavity, and the stability of the connection between the first bending limiting structure 125 and the first extension 1232 can be guaranteed, thereby ensuring the reliability of the first bending limiting structure 125 in limiting the first sidewall 1212.

[0148] The distance between the first bending limiting structure 125 and the top of the door shell 121 includes, but is not limited to, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc.

[0149] In some possible embodiments, see Figure 6 , Figure 7 and Figure 8 The first bending limiting structure 125 includes a limiting part 125A and a pressing part 125B. One end of the limiting part 125A is connected to the first bending sidewall 1214 and / or the second bending sidewall 1215. The limiting part 125A bends toward the foaming cavity and abuts against the edge of the first extension 1232. The pressing part 125B is connected to the other end of the limiting part 125A. The area of ​​the pressing part 125B is larger than the area of ​​the limiting part 125A.

[0150] Optionally, the limiting part 125A in the first sub-limiting structure 1251 is connected to the first bent sidewall 1214, and the limiting part 125A in the second sub-limiting structure 1252 is connected to the second bent sidewall 1215.

[0151] Since the area of ​​the pressing part 125B is larger than the area of ​​the limiting part 125A, when the first end cap is assembled on the door shell 121, it is convenient for the worker to press it so that the limiting part 125A bends toward the foaming cavity.

[0152] Similarly, the structure of the second bending limiting structure 126 is the same as that of the first bending limiting structure 125, that is, it includes a limiting part 125A and a pressing part 125B. One end of the limiting part 125A of the second bending limiting structure 126 is connected to the first bending side wall 1214 and / or the second bending side wall 1215. The limiting part 125A of the second bending limiting structure 126 bends toward the foaming cavity and abuts against the edge of the second extension 1242.

[0153] In some possible embodiments, see Figure 7 Both the limiting part 125A and the pressing part 125B are elongated structures. There is an angle between the length direction of the limiting part 125A and the length direction of the pressing part 125B. The length of the limiting part 125A is less than the length of the pressing part 125B.

[0154] The length direction of the limiting part 125A and the length direction of the pressing part 125B are at an angle. It should be understood that the angle can be an obtuse angle, an acute angle, a right angle, etc. For example, the length direction of the limiting part 125A and the length direction of the pressing part 125B are perpendicular to each other.

[0155] Since the length of the limiting part 125A is less than the length of the pressing part 125B, the contact area between the operator and the first bending limiting structure 125 can be increased when the first bending limiting structure 125 is pressed, thereby facilitating the bending of the limiting part 125A toward the foaming cavity.

[0156] Furthermore, the width of the limiting part 125A and the width of the pressing part 125B can be the same or different. For example, the width of the pressing part 125B is greater than the width of the limiting part 125A. The specific widths of the limiting part 125A and the pressing part 125B are not limited, as long as the limiting effect on the first side wall 1212 is reliable after the limiting part 125A is bent.

[0157] Furthermore, the specific lengths of the limiting part 125A and the pressing part 125B are not limited. Those skilled in the art can reasonably design the specific lengths of the limiting part 125A and the pressing part 125B based on the reliability of the limiting part 125A in limiting the first side wall 1212 and the contact area between the pressing part 125B and the operator.

[0158] In some possible embodiments, see Figure 7 and Figure 9 The limiting part 125A is connected to the end of the pressing part 125B, or the limiting part 125A is connected to the middle of the pressing part 125B. This simplifies the design of the first bending limiting structure 125.

[0159] When the limiting part 125A is connected to the end of the pressing part 125B, the first bending limiting structure 125 is an L-shaped structure; when the limiting part 125A is connected to the middle part of the pressing part 125B, the first bending limiting structure 125 is a T-shaped structure.

[0160] In some possible embodiments, see Figure 10 When the limiting part 125A is connected to the first bent side wall 1214, the distance between the pressing part 125B and the first bent side wall 1214 is b, 2mm≤b≤8mm, and / or the width of the limiting part 125A is d, 3mm≤d≤12mm.

[0161] If the distance between the pressing part 125B and the first bent sidewall 1214 is less than 2mm, after the limiting part 125A is bent, part of the pressing part 125B may abut against the edge of the first extension 1232, or the limiting part 125A may only abut against the edge of part of the first extension 1232, thus affecting the limiting effect of the limiting part 125A on the first sidewall 1212 and / or the second sidewall 1213. When the distance between 4 is greater than 8mm, the length of the limiting part 125A along its length direction will be too long. When the limiting part 125A bends toward the foaming cavity, the length of the limiting part 125A extending into the foaming cavity is too long, resulting in material waste. Based on this, the distance between the pressing part 125B and the first bent side wall 1214 is between 2mm and 8mm, which can reduce material waste while ensuring the limiting of the first side wall 1212 and / or the second side wall 1213.

[0162] If the width of the limiting part 125A is less than 3mm, then the limiting part 125A is too narrow, which will affect the strength of the limiting part 125A, and consequently affect the reliability of the limiting part 125A in limiting the first side wall 1212 and / or the second side wall 1213. If the width of the limiting part 125A is greater than 12mm, then the limiting part 125A is too wide, which is not conducive to the bending operation, thereby increasing the difficulty of the bending limiting operation. Based on this, the width of the limiting part 125A is made to be between 3mm and 12mm. In this way, the reliability of the limiting part 125A in limiting the first side wall 1212 and / or the second side wall 1213 after bending can be guaranteed while reducing the difficulty of the bending limiting operation.

[0163] For example, the distance between the pressing part 125B and the first bent sidewall 1214 can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc. The width of the limiting part 125A can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, etc. Those skilled in the art should understand that the above data are only illustrative examples and should not be construed as specific limitations on the distance between the pressing part 125B and the first bent sidewall 1214 or the width of the limiting part 125A.

[0164] In some possible embodiments, the first sub-limiting structure 1251 is integrally formed with the first bent sidewall 1214, and the second sub-limiting structure 1252 is integrally formed with the second bent sidewall 1215.

[0165] By integrally forming the first sub-limiting structure 1251 with the first bent sidewall 1214 and the second sub-limiting structure 1252 with the second bent sidewall 1215, the number of parts of the door body 120 can be reduced, thereby simplifying the assembly process of the door body 120.
