Description

Technical Field

[0001] The embodiments of the present application relate to household appliance technology, and more particularly to a refrigerator. Background Art

[0002] During the manufacturing process of refrigeration equipment products such as refrigerators and freezers, embedded parts are pre-installed or embedded. Embedded parts have multiple functions in the function and structure of the refrigerator, such as fixing lamps, electrical connection terminals, installing control panel accessories, etc.

[0003] In the related art, the embedded parts are usually embedded in the heat preservation layer of the refrigerator. During the processing, the processing personnel seal the embedded parts on the box or fixed parts of the refrigerator by sticking tape, and then foam the heat preservation layer.

[0004] However, the sealing reliability between the embedded parts and the box is poor. During the foaming process, the foaming material easily overflows into the embedded parts, blocking the functional components inside the embedded parts and affecting the product yield. Utility Model Content

[0005] The embodiments of the present application provide a technical field of household appliances to solve the technical problem of poor sealing reliability of embedded parts and box liner in the related art.

[0006] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0007] The box body comprises a box shell and a box liner, wherein the box liner is structured to form a storage compartment with an opening at the front side, the box shell is connected to the outer side of the box liner, and an insulation layer formed of a foaming material is formed between the box shell and the box liner;

[0008] The part of the box liner is recessed toward the box shell to form a mounting portion; the mounting portion includes a mounting bottom wall and a mounting side wall located at the front edge of the mounting bottom wall, and a mounting opening is formed on the mounting bottom wall;

[0009] A door body is rotatably mounted on the box shell to open or close the storage compartment;

[0010] The embedded box is fixed on the mounting portion; the embedded box comprises:

[0011] The box body is structured to form a housing cavity for accommodating functional components;

[0012] The connecting bottom wall is annular and encloses an opening communicating with the accommodating cavity, and the edge of the opening is connected to the box body; the connecting bottom wall is connected to the edge of the box body; the connecting bottom wall and the mounting bottom wall are opposite to each other along the direction from the box liner to the box shell, and the connecting bottom wall and the mounting bottom wall are attached and fixedly connected; the connecting bottom wall has an inner end close to the center of the box body, and an outer end away from the center of the box body;

[0013] An inner peripheral side wall is connected to the inner end of the connecting bottom wall, and the inner peripheral side wall is located at the front side of the connecting bottom wall; the inner peripheral side wall extends into the box liner through the installation opening;

[0014] The peripheral side wall is connected to the outer end of the connecting bottom wall and is located on the front side of the connecting bottom wall; the peripheral side wall is located on the side of the mounting portion away from the storage compartment, and at least part of the peripheral side wall is opposite to and in contact with the mounting side wall.

[0015] The refrigerator of the embodiment of the present application is provided with an installation portion on the box body for installing an embedded box, the installation portion includes an installation bottom wall and an installation side wall located at the front edge of the installation bottom wall, and an installation opening is formed on the installation bottom wall; the embedded box includes a box body, a connecting bottom wall, an inner peripheral side wall and an outer peripheral side wall, the outer peripheral side wall is in contact with the installation side wall to form a first layer of barrier to the foam material; the connecting bottom wall and the installation bottom wall are attached and fixedly connected to form a second layer of barrier to the foam material, and the first layer of barrier and the second layer of barrier intersect, thereby increasing the flow resistance of the foam material, slowing down the flow of the foam material, and improving the barrier effect on the foam material; the inner peripheral side wall extends to the inner side of the installation portion through the installation opening, which can block the foam material from flowing toward the inside of the embedded box; moreover, the inner peripheral side wall intersects with the connecting bottom wall to form a bending structure, which further increases the flow resistance of the foam material and helps to slow down the flow of the foam material.

[0016] In some embodiments of the present application, the embedded box further includes an adhesive member, and the adhesive member is respectively bonded to the connecting bottom wall and the installation bottom wall.

[0017] The embodiment of the present application realizes a fixed connection between the connecting bottom wall and the mounting bottom wall by setting an adhesive to bond the connecting bottom wall and the mounting bottom wall, and can also ensure that the connecting bottom wall and the mounting bottom wall are in contact with each other. Not only is the structure simple, but it is also conducive to forming a sealing structure between the connecting bottom wall and the mounting bottom wall, thereby improving the barrier effect on the foaming material.

[0018] In some embodiments of the present application, the adhesive member is an elastic adhesive member.

[0019] The adhesive component of the embodiment of the present application is elastic and can adapt to different gaps between the connecting bottom wall and the mounting bottom wall, thereby ensuring the stability and sealing performance of the connection between the connecting bottom wall and the mounting bottom wall and improving the barrier effect on the foaming material.

[0020] In some embodiments of the present application, the adhesive component covers the connecting bottom wall.

[0021] This can ensure that the annular connecting bottom wall fits the mounting bottom wall at all locations, which is beneficial to improving the barrier effect on the foaming material and also beneficial to improving the stability and reliability of the connection between the connecting bottom wall and the mounting bottom wall.

[0022] In some embodiments of the present application, the peripheral sidewall includes a first sidewall, a second sidewall, and two third sidewalls. The first sidewall and the second sidewall are spaced apart and opposite to each other in a first direction. The two third sidewalls are spaced apart and opposite to each other in a second direction, and both ends of the two third sidewalls are respectively connected to the first sidewall and the second sidewall. The dimension of the second sidewall in a third direction is smaller than the dimension of the first sidewall in the first direction. Wherein, the first direction, the second direction, and the third direction are perpendicular to each other pairwise. The first sidewall and the two third sidewalls are opposite to and in contact with the installation sidewall. The second sidewall is in contact with the installation bottom wall.

[0023] Through the above arrangement, the peripheral sidewall is opposite to and in contact with the installation sidewall through the first sidewall and the two third sidewalls, forming a relatively large contact area, which increases the flow resistance of the foaming material. And through the contact between the second sidewall and the installation bottom wall, bending structures are formed on all four sides of the connecting bottom wall, which increases the flow resistance of the foaming material.

[0024] In some embodiments of the present application, a resistance portion is provided on one side of the first sidewall and the two third sidewalls facing the inner peripheral sidewall for increasing the flow resistance of the foaming material.

[0025] The embodiments of the present application can form an uneven structure between the first sidewall and the fourth sidewall, and an uneven structure between the third sidewall and the fifth sidewall, thereby increasing the flow resistance of the foaming material and slowing down the fluidity of the foaming material.

[0026] In some embodiments of the present application, the resistance portion includes a plurality of strip portions, and the plurality of strip portions are arranged at intervals in the third direction. The strip portions on the first sidewall extend in the second direction, and the strip portions on the two third sidewalls extend in the first direction.

[0027] By providing a plurality of strip portions in the resistance portion, the contact surfaces between the first sidewall and the fourth sidewall and between the third sidewall and the fifth sidewall are non-planar, increasing the flow resistance.

[0028] In some embodiments of the present application, the installation bottom wall has a first side and a second side that are spaced apart and opposite to each other in the first direction, and the installation bottom wall has a third side and a fourth side that are spaced apart and opposite to each other in the second direction. The installation sidewall includes a fourth sidewall and two fifth sidewalls. The fourth sidewall is connected to the first side of the installation bottom wall and is in contact with the first sidewall. The two fifth sidewalls are respectively connected to the third side and the fourth side of the installation bottom wall. Along the direction from the first side to the second side of the installation bottom wall, the heights of the two fifth sidewalls gradually decrease. Wherein, the dimension of the two fifth sidewalls in the direction perpendicular to the installation bottom wall is the height.

[0029] Since the box liner is relatively large in size, when installing the embedded box, the force on the installation part is likely to deform the box liner. In the embodiments of the present application, by providing an inclined fifth side wall, the structural strength of the installation part is improved, thereby increasing the force-bearing strength of the installation part and reducing the possibility of the box liner deforming under force. Moreover, such a setting can also reserve sufficient space between the installation part and the box shell, providing sufficient space for the layout of the embedded box and functional components.

[0030] In some embodiments of the present application, the third side wall includes a first wall portion and a second wall portion. The height of the first wall portion is the same as the height of the first side wall. One end of the first wall portion is connected to the first side wall, and the other end of the second wall portion is connected to the second wall portion; the end of the second wall portion facing away from the first wall portion is connected to the second side wall; the second wall portion is inclined, and along the direction from the first side wall to the second side wall, the height of the second wall portion gradually decreases.

[0031] In some embodiments of the present application, by providing the first wall portion on the third side wall, the height of the first wall portion is the same as the height of the first side wall, which is beneficial to ensuring a large contact area between the first side wall and the bent portions on both sides thereof, thereby improving the blocking effect on the foaming material.

[0032] In some embodiments of the present application, the third side wall further includes an arc-shaped intermediate wall portion. One end of the intermediate wall portion is tangentially connected to the first wall portion, and the other end of the intermediate wall portion is connected to the second wall portion.

[0033] In the embodiments of the present application, by providing the intermediate wall portion, the first wall portion and the second wall portion are transitioned through the intermediate wall portion, which is beneficial to improving the structural strength of the third side wall.

[0034] In a second aspect, embodiments of the present application provide a refrigerator, which includes:

[0035] A box body, including a box shell and a box liner. The box liner is configured to form a storage compartment with an opening at the front side. The box shell is connected to the outside of the box liner, and a heat insulation layer is formed between the box shell and the box liner;

[0036] A door body, rotatably installed on the box shell to open or close the storage compartment;

[0037] An installation part, provided on the box liner or the door body; an installation opening is formed on the installation part;

[0038] The embedded box is fixed on the installation part; the embedded box is configured to form a connecting part, and the connecting part is annular; a part of the structure of the connecting part is located outside the installation part, and a bent contact surface is formed between the connecting part and the outside of the installation part; a part of the structure of the connecting part extends to the inside of the installation part through the installation opening.

[0039] In the refrigerator according to the embodiment of the present application, an installation part is provided to install the embedded box. The installation part can be arranged on the box body or the door body. The embedded box is configured to form an annular connecting part. A part of the structure of the connecting part is located outside the installation part, and a bent contact surface is formed between the connecting part and the outside of the installation part, which increases the flow resistance of the foaming material, thereby enhancing the blocking effect of the connecting part on the foaming material and reducing the possibility of the foaming material of the thermal insulation layer entering the embedded box; moreover, a part of the structure of the connecting part extends to the inside of the installation part through the installation opening, further improving the blocking effect on the foaming material. Even if the foaming material enters the inner box through the gap, due to the blocking effect of the connecting part, the possibility of the foaming material entering the embedded box is reduced.

[0055] To make the objectives, implementation manners and advantages of the present application clearer, the following will clearly and completely describe the exemplary implementation manners of the present application with reference to the accompanying drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0056] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the subsequent described implementation manners, rather than intending to limit the implementation manners of the present application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0057] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion. For example, a product or device including a series of components does not necessarily have to be limited to those components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0058] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0059] The terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0060] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected" and "coupled" shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0061] In the related art, the embedded parts are usually embedded in the insulation layer of the refrigerator. During the processing, the processing personnel seal the embedded parts on the refrigerator liner or the fixing parts by pasting tapes, and then carry out the foaming of the insulation layer.

[0062] The R & D personnel of the present application found that during the foaming process, the foaming material is likely to overflow into the embedded parts and block the functional devices inside the embedded parts. For example, when foaming after the terminal box is embedded, the foaming material enters the terminal box and blocks the electrical connection terminals inside the terminal box, which is difficult to clean. Moreover, the foaming material on the connection terminals cannot be cleaned thoroughly, which is likely to cause poor contact of the connection terminals and affect the normal operation of the refrigerator function.

[0063] The R & D personnel of the present application studied the installation method of the embedded parts. The embedded parts are usually bonded to the refrigerator liner or the fixing parts by tapes. Due to the bonding reliability and the differences in the skills of the operators, etc., the sealing reliability between the embedded parts and the refrigerator liner is poor, and the problem of material overflow is likely to occur during the foaming process, affecting the product yield and production efficiency.

[0064] To this end, an embodiment of the present application provides a pre-embedded box structure, a multi-layer barrier structure between the pre-embedded box and the installation part on the box liner, so as to improve the sealing reliability between the pre-embedded box and the installation part, and reduce the possibility of overflowing materials towards the inside of the box during the foaming process.

[0065] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0066] First of all, it should be noted that in the embodiments of the present application, the width direction of the refrigerator corresponds to the X-axis direction in the accompanying drawings; the thickness direction of the refrigerator corresponds to the Y-axis direction in the accompanying drawings; the height direction of the refrigerator, that is, the up and down direction, corresponds to the Z-axis direction in the accompanying drawings.

[0067] Combined Figure 1 , an embodiment of the present application provides a refrigerator, including a box body 100 and a door body. The box body 100 can be configured with a storage compartment 121. The door body can be rotatably connected to the box body 100 for opening or closing the storage compartment 121.

[0068] In some embodiments, the box body 100 may include a box shell 110. The box shell 110 serves as the outer shell of the refrigerator and is configured to form a chamber with an opening at the front side.

[0069] The box body 100 further includes a box liner 120. The box liner 120 is configured to form a storage compartment 121 with an opening at the front side, and the box liner 120 is connected inside the box shell 110.

[0070] The box body 100 further includes a heat insulation layer disposed between the box shell 110 and the box liner 120 to insulate the storage compartment 121, minimize the heat exchange between the storage compartment 121 and the outside of the refrigerator, and help ensure the refrigeration effect of the refrigerator.

[0071] Exemplarily, the heat insulation layer is formed by foaming a foaming material, which can fill the irregular space between the box shell 110 and the box liner 120 as much as possible and ensure the heat insulation performance of the box liner 120.

[0072] In some embodiments, a plurality of box liners 120 may be provided, so that the number of storage compartments 121 is multiple. The multiple storage compartments 121 can be divided into a refrigerating compartment, a freezing compartment, a variable temperature compartment, etc. according to different storage temperatures.

[0073] Exemplarily, Figure 1The number of the storage compartments 121 is one. Exemplarily, the number of the storage compartments 121 is two, and the two storage compartments 121 are arranged at intervals along the height direction or the width direction of the refrigerator, one of which is a refrigerating compartment and the other is a freezing compartment.

[0074] The door body may include a door inner liner and a door housing. The door inner liner may face the refrigerating compartment when the door body is in the closed state. The door housing may be connected to the outer side of the door inner liner to form the appearance of the refrigerator. The door housing may be rotatably connected to the box body.

[0075] The door body may further include a door heat insulation layer, and the door heat insulation layer may be disposed between the door inner liner and the door housing. The door heat insulation layer can keep the refrigerating compartment warm to minimize the heat exchange between the refrigerating compartment and the outside of the refrigerator, which is beneficial to ensuring the refrigeration effect of the refrigerator.

[0076] Exemplarily, the door heat insulation layer may be formed by foaming a foaming material, and has a good heat insulation effect.

[0077] The number of the door bodies may be correspondingly set according to the number of the storage compartments 121, and one door body is correspondingly set for each storage compartment 121.

[0078] The refrigerator according to the embodiment of the present application may further include a refrigeration system, and the refrigeration system may be disposed in the box body 100 to supply cold to the storage compartments.

[0079] Exemplarily, the refrigeration system may include a compressor, a condenser, a capillary tube and an evaporator that are connected in a cycle. When the refrigeration system operates, the compressor compresses the refrigerant vapor to generate high-temperature and high-pressure refrigerant vapor, and transports the refrigerant vapor into the condenser. The condenser liquefies the high-temperature and high-pressure refrigerant vapor to generate high-temperature and low-pressure refrigerant liquid, and transports it to the capillary tube. After the capillary tube reduces the pressure of the refrigerant liquid, the high-pressure and low-temperature refrigerant liquid is changed into low-pressure and low-temperature refrigerant liquid, and is transported to the evaporator. After receiving the low-pressure and low-temperature refrigerant liquid, the evaporator makes it boil under the isobaric condition, absorbs heat and vaporizes to form refrigerant vapor, so as to reduce the temperature in the storage compartment 121.

[0080] The refrigerator according to the embodiment of the present application further includes a buried box 200, and various functional components such as connection terminals, lighting lamps, panel control devices, etc. may be installed in the buried box 200.

[0081] The buried box 200 may be installed on the box body 100, and the buried box 200 may also be installed on the door body.

[0082] In some embodiments, in combination with Figure 2 , the refrigerator further includes a mounting portion 130, and the buried box 200 is fixed on the mounting portion 130.

[0083] When the installation part 130 is arranged on the door body, the embedded box 200 is arranged on the door body; when the installation part 130 is arranged on the box body 100, the embedded box 200 is arranged on the box body 100. In the embodiment of the present application, the case where the embedded box 200 is installed on the box body 100 is taken as an example for description.

[0084] Among them, in combination with Figure 3 and Figure 4 , a part of the box liner 120 is recessed towards the box shell 110 to form the installation part 130. On the inner surface of the box liner 120, the installation part 130 is in the shape of a groove; on the outer surface of the box liner 120, that is, the surface of the box liner 120 facing the box shell 110, the installation part 130 is in a convex shape.

[0085] The box liner 120 has a rear side wall, a top wall, a bottom wall, a left side wall and a right side wall, and together they enclose a storage compartment 121 with an opening at the front side. Among them, the installation part 130 can be arranged on any side wall of the box liner 120. For example, the installation part 130 is arranged on the rear side wall of the box liner 120; for another example, the installation part 130 is arranged on the top wall of the box liner 120. Since items need to be placed on the bottom wall of the box liner 120, the embedded box is usually not installed.

[0086] An installation opening 133 is formed on the installation part 130 so that at least a part of the embedded box 200 extends into the box liner 120 through the installation opening 133.

[0087] Among them, the shape of the installation opening 133 matches the cross-sectional shape of the part of the embedded box 200 passing through the installation opening 133, reducing the possibility of material overflowing into the box liner 120 through the edge of the installation opening 133. For example, the installation opening 133 is a rectangular opening, and the cross-sectional shape of the part of the embedded box 200 passing through the installation opening 133 is rectangular. Of course, this is not a limitation on the shape of the installation opening 133.

[0088] The embedded box 200 is fixed on the installation part 130. For example, the embedded box 200 is snap-connected to the installation part 130, or for another example, the embedded box 200 is adhesively connected to the installation part 130, etc.

[0089] Referring to Figure 4 , the embedded box 200 is constructed to form a connection part 220. The connection part 220 is in a ring shape, and the space enclosed by the connection part 220 is used to accommodate the functional component 300 or the structure connected to the functional component 300. Exemplarily, the functional component 300 is an electrical connection terminal.

[0090] In some embodiments, the embedded box 200 further includes a box body portion 210. The box body portion 210 is configured to form a receiving cavity 211. The space formed by the enclosure of the receiving cavity 211 and the connecting portion 220 is in communication, and is used to accommodate the functional component 300. At least a part of the functional component 300 is located within the receiving cavity 211, and a part of the structure of the functional component 300 may be located within the space between the inner liner 120 and the outer shell 110.

[0091] The shape of the connecting portion 220 matches the shape of the mounting opening 133 to enhance the blocking effect of the connecting portion 220 on the foaming material.

[0092] Wherein, a part of the structure of the connecting portion 220 is located outside the mounting portion 130. A bent contact surface is formed between the connecting portion 220 and the outside of the mounting portion 130 to increase the flow resistance of the foaming material, thereby enhancing the blocking effect of the connecting portion 220 on the foaming material. The outside of the mounting portion 130 is the side of the mounting portion 130 facing the outer shell 110.

[0093] A part of the structure of the connecting portion 220 extends through the mounting opening 133 to the inside of the mounting portion 130 to further block the foaming material and reduce the possibility of the foaming material entering the inside of the annular connecting portion 220. The inside of the mounting portion 130 is the side of the mounting portion 130 facing the storage compartment 121. Even if the foaming material enters the inner liner 120 through the gap, compared with the narrow space inside the embedded box 200, it is relatively easy to clean and will not affect the realization of the functions of the functional components 300 inside the embedded box 200.

[0094] In this way, by providing the connecting portion 220 in the embedded box 200 of the embodiment of the present application, a part of the structure is located outside the mounting portion 130, and a bent contact surface is formed between the connecting portion 220 and the outside of the mounting portion 130 to increase the flow resistance of the foaming material, thereby enhancing the blocking effect of the connecting portion 220 on the foaming material and reducing the possibility of the heat-insulating layer foaming material entering the embedded box 200; moreover, a part of the structure of the connecting portion 220 extends through the mounting opening 133 to the inside of the mounting portion 130 to further enhance the blocking effect on the foaming material. Even if the foaming material enters the inner liner 120 through the gap, due to the blocking effect of the connecting portion 220, the possibility of the foaming material entering the embedded box 200 is reduced.

[0095] In some embodiments, the connecting portion 220 forms a groove structure, and the opening of the groove structure faces the inside of the inner liner 120; the mounting portion 130 is embedded in the groove structure, so that a part of the structure of the connecting portion 220 extends through the mounting opening 133 to the inside of the mounting portion 130, and a part of the structure of the connecting portion 220 is located outside the mounting portion 130, and a bent contact surface is formed. The specific structures and functions of the connecting portion 220 and the mounting portion 130 of the embedded box 200 are described in detail below with reference to the accompanying drawings.

[0096] Combined with Figure 4, the installation part 130 includes an installation bottom wall 131 and an installation side wall 132, and the installation side wall 132 is located at the edge of the front side of the installation bottom wall 131.

[0097] An installation opening 133 is formed on the installation bottom wall 131. In some embodiments, the installation bottom wall 131 extends towards the inside of the installation opening 133 to form an anti-misalignment part 1310, and a mating part that mates with the anti-misalignment part 1310 is provided on the embedded box 200. Through the mating of the mating part and the anti-misalignment part 1310, the reverse installation of the embedded box 200 is avoided, and the assembly accuracy is improved.

[0098] Among them, the installation bottom wall 131 faces the box shell 110. The installation bottom wall 131 can be parallel to a part of the opposite box shell 110. For example, when the installation part 130 is arranged on the rear side wall of the box liner 120, the installation bottom wall 131 can be parallel to the rear side wall of the box shell 110. Or, an included angle can be formed between the installation bottom wall 131 and the rear side wall of the box shell 110, so that the installation bottom wall 131 is inclined relative to the rear side wall of the box shell 110. In this way, the functional components 300 in the embedded box 200 can be inclined components, providing sufficient space for the layout of the functional components 300. For example, the top end of the installation bottom wall 131 is inclined towards the interior of the storage room.

[0099] The installation side wall 132 is arranged at the edge of the installation bottom wall 131, and the installation side wall 132 can be perpendicular to the installation bottom wall 131. Among them, the installation side wall 132 can be annular, surrounding the edge of the installation bottom wall 131; the installation side wall 132 can be semi-annular, semi-surrounding the edge of the installation bottom wall 131.

[0100] In some embodiments, combined Figure 5 , the installation bottom wall 131 has a first outer peripheral side edge 1311 and a second outer peripheral side edge 1312 that are spaced apart and opposite in the first direction (corresponding to the D1 direction in the drawing), and the installation bottom wall 131 has a third outer peripheral side edge 1313 and a fourth outer peripheral side edge 1314 that are spaced apart and opposite in the second direction (corresponding to the D2 direction in the drawing). The first direction is perpendicular to the second direction.

[0101] The installation side wall 132 includes a fourth side wall 1321 and two fifth side walls 1322, and the fourth side wall 1321 is connected to the first outer peripheral side edge 1311 of the installation bottom wall 131.

[0102] Two fifth side walls 1322 are respectively connected to the third peripheral side 1313 and the fourth peripheral side 1314 of the mounting bottom wall 131; along the direction from the first peripheral side 1311 to the second peripheral side 1312 of the mounting bottom wall 131, the heights of the two fifth side walls 1322 gradually decrease; wherein, the dimension of the two fifth side walls 1322 in the direction perpendicular to the mounting bottom wall 131 is the height, that is, the dimension of the fifth side wall 1322 in the third direction D3 is its height. Thus, the two fifth side walls 1322 are inclined side walls.

[0103] Exemplarily, the height of the fifth side wall 1322 at the end close to the first peripheral side 1311 is the same as the height of the fourth side wall 1321, and the height of the fifth side wall 1322 gradually decreases to zero along the direction from the first peripheral side 1311 to the second peripheral side 1312 of the mounting bottom wall 131, so that the mounting part 130 is substantially in the shape of a dustpan. Thus, the fourth side wall 1321, the two fifth side walls 1322 and the second peripheral side 1312 of the mounting bottom wall 131 are connected to the box liner 120.

[0104] Since the size of the box liner 120 is large, when installing the embedded box 200, the force on the mounting part 130 is likely to deform the box liner 120. In the embodiment of the present application, by providing the inclined fifth side walls 1322, the structural strength of the mounting part 130 is improved, and then the force-bearing strength of the mounting part 130 is improved, reducing the possibility of the box liner 120 being deformed by force.

[0105] Moreover, such a setting can also reserve sufficient space between the mounting part 130 and the box shell 110, providing sufficient space for the layout of the embedded box 200 and the functional components 300.

[0106] Continue to refer to Figure 4 and Figure 5 , the connecting part 220 of the embedded box 200 includes a connecting bottom wall 230, the connecting bottom wall 230 is annular and encloses an opening communicating with the accommodating cavity 211, and the edge of the opening is connected to the box body part 210. Thus, the functional components 300 in the box liner 120 can be electrically connected to other electrical components through cables or the like passing through the opening.

[0107] The connecting bottom wall 230 is connected to the edge of the box body part 210. The connecting bottom wall 230 and the mounting bottom wall 131 are opposite in the direction from the box liner 120 to the box shell 110. The connecting bottom wall 230 and the mounting bottom wall 131 are attached and fixedly connected. Thus, the connecting bottom wall 230 and the mounting bottom wall 131 are parallel, and the connecting bottom wall 230 and the mounting bottom wall 131 are attached to each other, ensuring a surface fixed connection between the connecting bottom wall 230 and the mounting bottom wall 131, playing a role in blocking the foaming material.

[0108] In some embodiments, the surface contact when the connecting bottom wall 230 and the mounting bottom wall 131 are fitted together is utilized, as well as the fixed connection between the two. The fixed connection methods include but are not limited to snap connection, bonding, etc. In this way, the reliability of the contact between the connecting bottom wall 230 and the mounting bottom wall 131 can be ensured, and the possibility of the foaming material overflowing through the gap between the embedded box 200 and the mounting portion 130 can be reduced.

[0109] In some embodiments, the embedded box 200 further includes an adhesive member 260, and the adhesive member 260 is bonded to the connecting bottom wall 230 and the mounting bottom wall 131 respectively. With such a setting, not only can the fixed connection between the connecting bottom wall 230 and the mounting bottom wall 131 be achieved by using the adhesive member 260, but also the surface fitting between the connecting bottom wall 230 and the mounting bottom wall 131 can be ensured. It is not only simple in structure, but also conducive to forming a sealing structure between the connecting bottom wall 230 and the mounting bottom wall 131, improving the barrier effect on the foaming material.

[0110] The adhesive member 260 is a part of the embedded box 200. Thus, when assembling the embedded box 200 to the box liner 120 on-site, the operator does not need to perform on-site sealing treatment on the embedded box 200, which is not only conducive to improving efficiency, but also can avoid the overflow problem caused by the operator's improper bonding of the tape on-site, improving the processing quality.

[0111] Of course, in some implementation manners, the adhesive member 260 can be bonded to the connecting bottom wall 230, and the adhesive member 260 abuts against the mounting bottom wall 131; or, the adhesive member 260 can be bonded to the mounting bottom wall 131, and the adhesive member 260 abuts against the connecting bottom wall 230. In this way, the adhesive member 260 plays a sealing role. At this time, the connecting bottom wall 230 and the mounting bottom wall 131 can be fixedly connected by other means such as snap connection.

[0112] Due to processing errors, installation errors, etc., the gaps between the connecting bottom wall 230 and the mounting bottom wall 131 are different. In some embodiments, the adhesive member 260 is an elastic adhesive member. Thus, the elasticity of the adhesive member 260 can adapt to the different gaps between the connecting bottom wall 230 and the mounting bottom wall 131, ensuring the stability and sealing performance of the connection between the connecting bottom wall 230 and the mounting bottom wall 131, and improving the barrier effect on the foaming material.

[0113] Exemplarily, the adhesive member 260 is a double-sided adhesive sponge, a double-sided adhesive foam, etc.

[0114] In some embodiments, the adhesive member 260 covers the connecting bottom wall 230. In this way, it can be ensured that all parts of the annular connecting bottom wall 230 are fitted with the mounting bottom wall 131, which is conducive to improving the barrier effect on the foaming material, and also conducive to improving the stability and reliability of the connection between the connecting bottom wall 230 and the mounting bottom wall 131.

[0115] Exemplarily, the connecting bottom wall 230 is in a rectangular ring shape, and the bonding member 260 is in a rectangular ring shape, ensuring a large fitting area between the connecting bottom wall 230 and the mounting bottom wall 131, thereby facilitating the improvement of the connection stability between the connecting bottom wall 230 and the mounting bottom wall 131, facilitating the improvement of the sealing performance between the connecting bottom wall 230 and the mounting bottom wall 131, and thus improving the barrier effect on the foaming material.

[0116] In some embodiments, the bonding member 260 can partially cover the mounting bottom wall 131, that is, the part of the mounting bottom wall 131 opposite to the connecting bottom wall 230 is bonded to the bonding member 260, and a part of the mounting bottom wall 131 abuts against a part of the side wall of the connecting portion 220.

[0117] In some embodiments, the bonding member 260 can completely cover the mounting bottom wall 131. In this way, not only can the mounting bottom wall 131 and the connecting bottom wall 230 be bonded, but also a part of the side wall of the connecting portion 220 can be bonded to the mounting bottom wall 131, which is beneficial to improving the connection possibility and sealing performance between the connecting portion 220 and the mounting portion 130.

[0118] Continue to refer to Figure 6 and Figure 7 , the connecting bottom wall 230 has opposite inner and outer ends. The inner end of the connecting bottom wall 230 is close to the inner end of the center of the box body portion 210, and the outer end of the connecting bottom wall 230 faces away from the center of the box body portion 210.

[0119] The connecting portion 220 of the embedded box 200 further includes an inner peripheral side wall 240, and the inner peripheral side wall 240 is connected to the inner end of the connecting bottom wall 230. The inner peripheral side wall 240 is located on the front side of the connecting bottom wall 230, and the inner peripheral side wall 240 extends into the box liner 120 through the mounting opening 133.

[0120] The inner peripheral side wall 240 intersects with the connecting bottom wall 230. For example, the inner peripheral side wall 240 is perpendicular to the connecting bottom wall 230. In this way, by setting the inner peripheral side wall 240 to pass through the mounting opening 133, the direction of the contact surface between the connecting bottom wall 230 and the mounting bottom wall 131 is changed, which is beneficial to slowing down the flow of the foaming material; moreover, the inner peripheral side wall 240 extends into the recessed mounting portion 130 through the mounting opening 133, and can block the foaming material from flowing towards the inside of the embedded box 200.

[0121] Even if the foaming material overflows into the box liner 120 through the gap between the connecting bottom wall 230 and the mounting bottom wall 131, due to the blocking effect of the inner peripheral side wall 240, the foaming material overflows towards the box liner 120, reducing the possibility of overflowing into the embedded box 200. Compared with cleaning the overflow material in the embedded box 200, cleaning the overflow material in the box liner 120 is relatively simple and has less impact on the functional components 300 of the embedded box 200.

[0122] When the connecting bottom wall 230 is in a rectangular ring shape, the inner peripheral side wall 240 is formed into a rectangular ring shape by four side walls.

[0123] In some embodiments, in combination Figure 8 Along the second direction, a matching notch 241 is provided at the top corner of the top of the inner peripheral side wall 240. Figure 5 A protruding anti-mistake portion 1310 is provided on the installation bottom wall 131. The anti-mistake portion 1310 cooperates with the matching notch 241 to prevent the possibility of the embedded box 200 being installed upside down.

[0124] In some embodiments, along the second direction, a wire-passing notch 242 is provided on the side wall at the bottom side of the inner peripheral side wall 240 to allow a cable connected to the functional component 300 to pass through.

[0125] The connecting portion 220 of the embedded box 200 further includes: an outer side wall 250, which is connected to the outer end of the connecting bottom wall 230, and the outer side wall 250 is located at the front side of the connecting bottom wall 230. In this way, the outer side wall 250 is opposite to the inner side wall 240 and has a gap, and the outer side wall 250 is sleeved on the outer side of the inner side wall 240.

[0126] The peripheral side wall 250 is located on the side of the mounting portion 130 away from the storage compartment, that is, the peripheral side wall 250 is located outside the mounting portion 130, and at least a portion of the peripheral side wall 250 is opposite to and in contact with the mounting side wall 132, thereby further blocking the foaming material.

[0127] The peripheral side wall 250 intersects with the connecting bottom wall 230, for example, the peripheral side wall 250 is perpendicular to the connecting bottom wall 230. In this way, the contact surface between the peripheral side wall 250 and the installation side wall 132 intersects with the fitting surface between the connecting bottom wall 230 and the installation side wall 132, so that the contact surface between the embedded box 200 and the installation portion 130 forms a bent shape, increasing the flow resistance of the foaming material and strengthening the barrier effect on the foaming material.

[0128] The outer side wall 250 , the connecting bottom wall 230 and the inner side wall 240 are combined to form an annular groove structure. The opening of the groove structure faces the interior of the box 120 , and the mounting portion 130 is embedded in the groove structure.

[0129] With the above settings, the outer peripheral side wall 250 contacts the mounting side wall 132 to form the first layer of barrier to the foaming material; the connecting bottom wall 230 and the mounting bottom wall 131 are attached and fixedly connected to form the second layer of barrier to the foaming material, and the first layer of barrier and the second layer of barrier intersect, increasing the flow resistance of the foaming material, slowing down the flow of the foaming material, and improving the barrier effect on the foaming material; the inner peripheral side wall 240 extends to the inside of the mounting portion 130 through the mounting opening 133, which can prevent the foaming material from flowing towards the inside of the embedded box 200; moreover, the inner peripheral side wall 240 intersects with the connecting bottom wall 230 to form a bending structure, further increasing the flow resistance of the foaming material and facilitating the slowing down of the flow of the foaming material.

[0130] Combined with Figure 7 and Figure 8 , in some embodiments, the outer peripheral side wall 250 includes a first side wall 251, a second side wall 252, and two third side walls 253.

[0131] The first side wall 251 and the second side wall 252 are spaced opposite to each other in the first direction (corresponding to the D1 direction in the drawing), the two third side walls 253 are spaced opposite to each other in the second direction (corresponding to the D2 direction in the drawing), and the two ends of the two third side walls 253 are respectively connected to the first side wall 251 and the second side wall 252. In this way, the first side wall 251, one third side wall 253, the second side wall 252, and the other third side wall 253 are connected end to end in sequence to enclose a rectangular ring-shaped outer peripheral side wall 250.

[0132] The first side wall 251 and the two third side walls 253 are opposite to and in contact with the mounting side wall 132. Among them, the first side wall 251 is opposite to and in contact with the fourth side wall 1321 in the first direction, and the two third side walls 253 are opposite to and in contact with the two fifth side walls 1322 in the second direction.

[0133] The dimensions of the first side wall 251, the second side wall 252, and the third side wall 253 in the third direction (corresponding to the D3 direction in the drawing) are the height. The third direction, the second direction, and the first direction are perpendicular to each other in pairs. The height of the second side wall 252 is less than the height of the first side wall 251. The second side wall 252 contacts the mounting bottom wall 131, and the bonding member 260 is enclosed in the space between the connecting portion 220 and the mounting portion 130.

[0134] With the above settings, the outer peripheral side wall 250 is opposite to and in contact with the mounting side wall 132 through the first side wall 251 and the two third side walls 253, forming a large contact area, increasing the flow resistance of the foaming material; and through the contact between the second side wall 252 and the mounting bottom wall 131, bending structures are formed on the four sides of the connecting bottom wall 230, increasing the flow resistance of the foaming material.

[0135] In some embodiments, combined with Figure 7 andFigure 8 At least one of the first side wall 251 and the fourth side wall 1321 is provided with a resistance portion 270 to increase the flow resistance of the foaming material between the first side wall 251 and the fourth side wall 1321 and slow down the fluidity of the foaming material.

[0136] In some embodiments, at least one of the two third side walls 253 and the two fifth side walls 1322 is provided with a resistance portion 270 to increase the flow resistance of the foaming material between the third side wall 253 and the fifth side wall 1322 and slow down the fluidity of the foaming material.

[0137] In some possible implementation manners, the resistance portion 270 is provided on one side of the first side wall 251 and the two third side walls 253 facing the inner peripheral side wall 240 for increasing the flow resistance of the foaming material. In this way, without changing the forming mold of the box liner 120, only the embedded box 200 needs to be improved, and the structure is simple and easy to implement.

[0138] Among them, the resistance portion 270 may be an uneven structure, for example, a wavy structure formed with convex and concave structures, to increase the contact bendability between the two side walls, thereby increasing the flow resistance of the foaming material.

[0139] In some embodiments, the resistance portion 270 includes a plurality of strip portions 271, and the plurality of strip portions 271 are arranged at intervals along the third direction (corresponding to the D3 direction in the drawings).

[0140] Among them, the strip portions 271 on the first side wall 251 extend along the second direction. The strip portions 271 on the two third side walls 253 extend along the first direction.

[0141] The strip portion 271 may be a long strip-shaped protrusion provided on the side wall, or the strip portion 271 may be a long strip-shaped groove provided on the side wall. In this way, a corrugated surface is formed on the first side wall 251 and the two third side walls 253, increasing the flow resistance of the foaming material.

[0142] By providing a plurality of strip portions 271, the resistance portion 270 makes the contact surface between the first side wall 251 and the fourth side wall 1321 a non-planar surface, and the contact surface between the third side wall 253 and the fifth side wall 1322 a non-planar surface, increasing the flow resistance.

[0143] Combined Figure 7 and Figure 9 In order to adapt to the inclined fifth side wall 1322, the third side wall 253 is an inclined side wall.

[0144] Among them, the third side wall 253 includes a first wall portion 2531 and a second wall portion 2532. The height of the first wall portion 2531 is the same as that of the first side wall 251. The height of the first wall portion 2531 is the dimension of the first wall portion 2531 along the third direction, and the height of the first side wall 251 is the dimension of the first side wall 251 along the third direction.

[0145] Among them, one end of the first wall portion 2531 is connected to the first side wall 251, and the other end of the first wall portion 2531 is connected to the second wall portion 2532. One end of the second wall portion 2532 facing away from the first wall portion 2531 is connected to the second side wall 252.

[0146] The second wall portion 2532 is inclined, and along the direction from the first side wall 251 to the second side wall 252, the height of the second wall portion 2532 gradually decreases.

[0147] The height of the second side wall 252 is less than that of the first side wall 251. One end of the second wall portion 2532 connected to the first wall portion 2531 has a larger height, and one end of the second wall portion 2532 connected to the second side wall 252 has a smaller height. In this way, the second wall portion 2532 is inclined.

[0148] In some embodiments of the present application, by providing the first wall portion 2531 on the third side wall 253, and the height of the first wall portion 2531 being the same as that of the first side wall 251, it is beneficial to ensure that the first side wall 251 and the bent portions on both sides thereof have a larger contact area, thereby improving the blocking effect on the foaming material.

[0149] If the second wall portion 2532 protrudes from the fifth side wall 1322, it will additionally increase the gap, resulting in an increased risk of foaming material overflow. By providing the inclined second wall portion 2532 on the third side wall 253, it is adapted to the inclined fifth side wall 1322, reducing the risk of foaming material overflow.

[0150] In some embodiments, the third side wall 253 further includes an arc-shaped intermediate wall portion 2533. One end of the intermediate wall portion 2533 is tangentially connected to the first wall portion 2531, and the other end of the intermediate wall portion 2533 is connected to the second wall portion 2532. Of course, the other end of the intermediate wall portion 2533 can be tangentially connected to the second wall portion 2532, so that the first wall portion 2531 and the second wall portion 2532 are transitioned through the intermediate wall portion 2533, which is beneficial to improving the structural strength of the third side wall 253.

[0151] Among them, the intermediate wall portion 2533 can be a section of arc-shaped wall portion, and the intermediate wall portion 2533 can include multiple sections of arc-shaped wall portions connected tangentially.

[0152] The inner end of the connecting bottom wall 230 is annular. The annular inner end of the connecting bottom wall 230 has a first side and a second side that are opposite to each other in the first direction. The annular inner end of the connecting bottom wall 230 also has a third side and a fourth side that are opposite to each other in the second direction.

[0153] Combine Figure 10 , in some embodiments, the box body portion 210 includes a first box wall 212 and a second box wall 213. One end of the first box wall 212 is connected to the first side of the annular inner end, the other end of the first box wall 212 is connected to the second box wall 213, and the end of the second box wall 213 facing away from the first box wall 212 is connected to the first side of the annular inner end.

[0154] In this way, the plane where the first box wall 212, the second box wall 213, and the connecting bottom wall 230 are located encloses a triangular structure.

[0155] The box body portion 210 further includes two third box walls 214, and the third box walls 214 are triangular. The two third box walls 214 are respectively connected to the third side and the fourth side of the annular inner end, and the two third box walls 214 are respectively connected to the two sides of the first box wall 212 and the second box wall 213 in the second direction. In this way, the first box wall 212, the second box wall 213, and the two third box walls 214 together enclose the accommodation cavity 211 of the box body portion 210.

[0156] In some embodiments, a hollow portion 216 is provided on the second box wall 213 for installing functional components, such as connection terminals. At least part of the functional component is accommodated in the accommodation cavity 211 through the hollow portion 216.

[0157] In some embodiments, protrusions 215 are provided on the two third box walls 214, and the protrusions 215 protrude away from the accommodation cavity 211. In this way, not only can the structural strength of the box body portion 210 be improved, but also it is beneficial to increase the outer surface area of the third box walls 214, so as to provide more adhesion positions for the foaming material, thereby improving the strength of the foaming material adhering to the third box walls 214.

[0158] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
