The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0070] Please refer to Figure 1 , the embodiment of the present application provides a box assembly 100, which is applied to an outdoor unit of an air conditioner. The outdoor unit of the air conditioner is a very important component in the air conditioning system and is mainly responsible for cooling and dissipating heat the high-pressure and high-temperature gas discharged from the indoor unit through a fan, and then sending the condensed refrigerant liquid back to the indoor unit for circulation. Its main components include a condenser, a temperature sensor, a compressor, a four-way valve, and a control board, etc. The box assembly 100 includes a box 10 and a motor bracket 20. The box 10, as the main structure of the box assembly 100, provides protection and support for the internal structure. An installation cavity 10a is provided in the box 10. The motor bracket 20 is arranged in the installation cavity 10a. The motor bracket 20 is at least used for installing and fixing the motor 200 of the outdoor unit of the air conditioner to ensure the stable operation of the motor 200. The motor bracket 20 is also used to provide support for the installation of part of the box 10.

[0071] Exemplarily, as Figure 3As shown, the shape of the box body 10 is generally a rectangular body. The box body 10 includes a front panel 11 and a rear side panel 15 that are oppositely arranged along the front-rear direction AA, a left side panel 13 and a right side panel 14 that are oppositely arranged along the left-right direction BB, and a top shell 12 and a base 16 that are oppositely arranged along the up-down direction DD. The front panel 11, the rear side panel 15, the left side panel 13, the right side panel 14, the top shell 12, and the base 16 enclose and define the above-mentioned installation cavity 10a. The shape of the installation cavity 10a is also relatively square, which is convenient for the installation of other components, such as the motor bracket 20. The box body 10 can be a sheet metal box body. Sheet metal materials (such as steel plates, aluminum plates, etc.) have high strength and rigidity, which can provide good mechanical support to ensure the stability of the box body 10. And the outer surface of the sheet metal box body 10 has a spray coating, which can provide a layer of anti-corrosion protective film for the sheet metal box body 10 to prevent the metal surface from rusting or corroding due to exposure to the outdoor environment.

[0072] As Figure 2 and Figure 4 As shown, the motor bracket 20 is also used to connect with the front panel 11. One of the front panel 11 and the motor bracket 20 is provided with a hook 1121, and the other of the front panel 11 and the motor bracket 20 is provided with a hanging hole 21. The hook 1121 and the hanging hole 21 are hung and connected. Through the design of the hook 1121 and the hanging hole 21, the connection between the front panel 11 and the motor bracket 20 is made more stable, enhancing the overall structural stability of the outdoor unit of the air conditioner. The front panel 11 can be pre-positioned and fixed with the motor bracket 20, reducing the need for manual assistance during the installation process, thereby improving the installation efficiency of the front panel 11. And when the operator installs the front panel 11, there is no need to perform the support and fixation work at the same time, reducing the labor intensity. It makes the operation of the front panel 11 of the installation cavity 10a simpler, reduces the operation steps, and improves the installation convenience.

[0073] Furthermore, the pre-fixing mechanism of the hook 1121 and the hanging hole 21 can also reduce the risk of accidental detachment of the front panel 11 during the installation process, improving the safety of the operation.

[0074] As Figure 4 As shown, exemplarily, the front panel 11 is provided with a hook 1121, and the side of the motor bracket 20 close to the front panel 11 is provided with a hanging hole 21. During installation, the front panel 11 can first be hung on the motor bracket 20 through the hook 1121. During operation, the fixing parts can be installed without manual support, reducing the labor intensity of the operator. Or, the motor bracket 20 is provided with a hook 1121, and the front panel 11 is provided with a hanging hole 21 adapted to the hook 1121. During installation, the front panel 11 is hung on the motor bracket 20 through the hanging hole 21, and the same effect can also be achieved.

[0075] As Figure 3 and Figure 4As shown, in some embodiments, the front panel 11 is provided with a plurality of hooks 1121, and the motor bracket 20 is correspondingly provided with a plurality of hanging holes 21. The plurality of hooks 1121 are respectively hung on the corresponding plurality of hanging holes 21, which can make the pressure on the front panel 11 more evenly distributed on the motor bracket 20, reduce the burden on a single hook 1121 or hanging hole 21, improve the stability when the front panel 11 is pre-fixed on the motor bracket 20, and reduce the loosening or displacement that may occur to the front panel 11 during the installation process. Moreover, even if a certain hook 1121 or hanging hole 21 is damaged, the other hooks 1121 and hanging holes 21 can still maintain the fixation of the front panel 11, reduce the risk of the front panel 11 falling off, and improve the safety of use. Exemplarily, the plurality of hooks 1121 can be evenly spaced along the left-right direction BB of the cabinet 10 on the front panel 11 to ensure that the front panel 11 is evenly stressed in the left-right direction BB and avoid deformation or distortion of the front panel 11 caused by uneven stress.

[0076] Please continue to refer to Figure 4 , further, after providing a preliminary pre-fixation through the hanging connection of the hooks 1121 and the hanging holes 21, in order to firmly install the front panel 11 and the motor bracket 20 together, the cabinet assembly 100 further includes a screwing member 30. The front panel 11 has a first mounting hole 11a, and the motor bracket 20 has a second mounting hole 20a. The first mounting hole 11a is aligned with the second mounting hole 20a. The screwing member 30 can pass through the first mounting hole 11a and the second mounting hole 20a. The screwing member 30 is used to provide a fastening force to screw the front panel 11 and the motor bracket 20, forming a dual fixation mechanism and enhancing the stability of the connection between the front panel 11 and the motor bracket 20. Setting the screwing member 30 can ensure that the front panel 11 will not loosen or fall off during long-term use, improving the safety of the air conditioner outdoor unit. Moreover, the method of opening the first mounting hole 11a and the second mounting hole 20a to install the screwing member 30 can adapt to front panels 11 of different sizes and shapes, and only need to adjust the positions of the first mounting hole 11a and the second mounting hole 20a and the size of the screwing member 30, improving the flexibility of the design.

[0077] Exemplarily, the screwing member 30 can be a screw, and both the first mounting hole 11a and the second mounting hole 20a are threaded holes, and can be directly screwed into the threaded holes to connect the front panel 11 and the motor bracket 20. Or, the screwing member 30 is a bolt and a nut, and both the first mounting hole 11a and the second mounting hole 20a are through holes. After passing the bolt through the two through holes, the front panel 11 and the motor bracket 20 are fastened with a nut.

[0078] In actual installation operations, the second mounting hole 20a is formed on the motor bracket 20, and the motor bracket 20 is located within the installation cavity 10a. The first mounting hole 11a is formed on the front panel 11. It is more convenient for the operator to pass the screw member 30 through the first mounting hole 11a and the second mounting hole 20a in sequence, that is, to install the screw member 30 facing the front panel 11.

[0079] As Figure 3 shown, in some embodiments, after the front panel 11 and the motor bracket 20 are fixed, the front panel 11, the rear side panel 15, the left side panel 13, the right side panel 14, and the base 16 form an upwardly open frame. It is necessary to connect the top shell 12 to the front panel 11, that is, the top shell 12 is covered and connected to the frame to form a complete box 10. Since the screw member 30 protrudes from the front panel 11, when the top shell 12 is covered, during installation, the top shell 12 needs to be forcibly inserted after being interference-fitted with the screw member 30 installed on the front panel 11. The assembly difficulty is high. It is not easy to install the top shell 12 and it is also easy to scratch and damage the outer spray coating of the top shell 12 due to the screw member 30, which may lead to corrosion and rust in the damaged area of the spray coating.

[0080] As Figures 5 - 7 shown, to solve the above problems, the front panel 11 includes a main board 111 and a bracket connecting plate 112. The main board 111 is the main part of the front panel 11, and an air outlet 11b is formed on the main board 111 to provide a heat dissipation channel for air outlet. The bracket connecting plate 112 extends along the left-right direction BB of the box 10, and the bracket connecting plate 112 is connected to the top end of the main board 111. Among them, the first mounting hole 11a and the hook 1121 are both provided on the bracket connecting plate 112. The bracket connecting plate 112 is used for cooperative assembly with the screw member 30 and the hanging hole 21 on the motor bracket 20 to fix the front panel 11. And along the front-rear direction AA of the box 10, the bracket connecting plate 112 is closer to the rear side panel 15 than the main board 111, so as to form a clearance space between the bracket connecting plate 112 and the top shell 12. The clearance space between the bracket connecting plate 112 and the top shell 12 ensures that a part of the screw member 30 is located within this space, that is, the screw member 30 is spaced from the inner wall of the top shell 12, avoiding scratching of the inner wall of the top shell 12 by the screw member 30. This not only simplifies the installation process of the top shell 12, prevents corrosion and rust caused by damage to the spray coating, protects the spray coating on the outer surface of the top shell 12, but also improves the durability and appearance integrity of the box 10.

[0081] Furthermore, the main board 111 and the bracket connecting plate 112 are of an integrally formed structure. The bracket connecting plate 112 can be bent by processes such as stamping. The integrally formed structure can reduce the connection points between the main board 111 and the bracket connecting plate 112, thereby reducing stress concentration and potential fracture points, making the overall structure of the front panel 11 more robust.

[0082] As Figure 3 , Figure 10 and Figure 11 shown, in some embodiments, the front panel 11 further includes a left connecting plate 114 and a right connecting plate 115. The left connecting plate 114 is connected to the left edge of the main board 111, and the right connecting plate 115 is connected to the right edge of the main board 111. Among them, the top end of the left connecting plate 114 has a left hook 1141, and the left hook 1141 is hooked to the top end of the left plate 13. A first hanging hole 21 adapted thereto is provided at the top end of the left plate 13; the top end of the right connecting plate 115 has a right hook, and the right hook is hooked to the top end of the right plate 14. A second hanging hole 21 adapted thereto is provided at the top end of the right plate 14; on the one hand, both the left hook 1141 and the right hook can provide pre - fixation for the installation of the front panel 11, reducing the alignment adjustment of the front panel 11 during the installation process and improving the installation efficiency.

[0083] On the other hand, through the cooperation of the left hook 1141 and the first hanging hole 21, and / or the cooperation of the right hook and the second hanging hole 21, the upper end of the front panel 11 can be flipped relative to the left plate 13 and / or the right plate 14. Through the flipping action, the hook 1121 can directly penetrate into the hanging hole 21, making it easier for the hook 1121 and the hanging hole 21 of the motor bracket 20 to be aligned, and simplifying the installation process.

[0084] As Figure 3 and Figure 7 shown, in some embodiments, the top shell 12 includes a main shell 121 and a front apron 122. The main shell 121 covers the upper part of the motor bracket 20, and the main shell 121 is used to protect the internal structure from the external environment. The front apron 122 is a front extension part of the top shell 12 and is connected to the front side edge of the main shell 121 at an angle. The front apron 122 is used to connect to the frame body to provide additional structural support. Among them, the screw member 30 includes a screw head 31. The screw head 31 is located between the front apron 122 and the bracket connecting plate 112 and is spaced from the front apron 122, which can prevent the end of the screw head 31 from rubbing against the front apron 122, avoid direct contact between the screw head 31 and the front apron 122, and reduce the damage or wear of the front apron 122 caused by the protrusion of the screw head 31, thereby extending the service life of the front apron 122.

[0085] As Figure 8 and Figure 9As shown, in some embodiments, the front panel 11 further includes a top shell connecting plate 113. The top shell connecting plate 113 is connected to the top end of the main board 111 and extends along the left-right direction BB of the box body 10. Among them, the top shell connecting plate 113 is used to connect the front panel 11 and the top shell 12 to ensure their correct alignment during installation. And along the left-right direction BB of the box body 10, the top shell connecting plate 113 is located on the left side or the right side of the bracket connecting plate 112, or on both the left and right sides, according to specific design and installation requirements. And along the front-back direction AA, the top shell connecting plate 113 is located between the bracket connecting plate 112 and the main board 111, so that after the top shell 12 covers the front panel 11, the front enclosure panel 122 and the main board 111 are substantially in the same plane in the vertical direction, which helps to keep the appearance of the front enclosure panel 122 and the main board 111 flat and consistent, improves the aesthetics of the product, and enhances the stability of the entire box body 10, reducing stress concentration and deformation caused by uneven transition of the outer surface of the structure. Among them, the top shell connecting plate 113 is screwed to the front enclosure panel 122, ensuring a firm connection between the top shell 12 and the front panel 11 and improving the stability of the box body 10.

[0086] As Figure 3 and Figure 4 As shown, in some embodiments, the top shell connecting plate 113 includes a vertical section 1132 and an arc-shaped guiding section 1133. The vertical section 1132 is connected to the top end of the main board 111, playing a role in fixing and supporting the top shell 12 and the front panel 11. The arc-shaped guiding section 1133 is connected to the end of the vertical section 1132 far from the main board 111, and the arc-shaped guiding section 1133 extends in an arc from the vertical section 1132 towards the rear side panel 15, and will not form an opposing top with the front enclosure panel 122, making the installation process of the top shell 12 smoother and reducing the resistance during the installation process. The arc-shaped guiding section 1133 is used to guide the correct alignment of the top shell 12 during the installation of the top shell 12, so that the top shell 12 can be more naturally aligned and fixed during installation, reducing the adjustment and alignment time during the installation process.

[0087] As Figure 8 and Figure 9 As shown, in some embodiments, the hook 1121 includes a connecting portion 1121a and a hook portion 1121b. The connecting portion 1121a is connected to the bracket connecting plate 112 and passes through the hanging hole 21 and abuts against the inner wall of the hanging hole 21. The connecting portion 1121a is used to bear the weight of the front panel 11. The hook portion 1121b is connected to the end of the connecting portion 1121a far from the bracket connecting plate 112 and is arranged at an angle α with the vertical plane. The hook portion 1121b is bent towards the direction of the base 16. The hook portion 1121b can limit the displacement of the front panel 11 in the front-back direction AA of the box body 10. Among them, α is not less than 5° and not greater than 10°, so that the hook 1121 can be better inserted into the hanging hole 21 during hanging, improving the convenience of installation.

[0088] like Figure 8 and Figure 9 As shown, in some embodiments, a first reinforcing rib 1122 is provided on the bracket connecting plate 112, and a second reinforcing rib 1131 is provided on the top shell connecting plate 113. The first reinforcing rib 1122 and the second reinforcing rib 1131 are both extended along the left-right direction BB of the box body 10. The first reinforcing rib 1122 is used to enhance the local strength and rigidity of the bracket connecting plate 112, so that the bracket connecting plate 112 can better withstand the force generated when the front panel 11 is connected to the motor bracket 20. Since the first reinforcing rib 1122 improves the rigidity of the bracket connecting plate 112, it can effectively prevent the front panel 11 and the motor bracket 20 from loosening due to insufficient strength, ensure the stability of the connection, reduce the potential safety hazards caused by loose connection, and improve the overall safety performance of the air conditioner outdoor unit. The second reinforcing rib 1131 is used to enhance the local strength and rigidity of the top shell connecting plate 113. The reinforcing rib helps prevent the top shell connecting plate 113 from bending or twisting when subjected to force, and maintains the integrity of its shape and structure, especially when subjected to lateral or longitudinal forces. By increasing the strength of the top shell connecting plate 113 , the service life of the top shell connecting plate 113 can be extended and damage caused by material fatigue can be reduced.

[0089] In some embodiments, the second reinforcing rib 1131 is at least partially arched toward the front panel 122 to form an arc-shaped surface. Before the top shell 12 is screwed to the front panel 11, the second reinforcing rib 1131 can provide preliminary fixation and support to limit the movement and shaking of the top shell 12; it can also reduce the adjustment and alignment time during installation, making the installation process smoother, thereby improving installation efficiency.

[0090] like Figure 8 As shown, in some embodiments, multiple first reinforcing ribs 1122 and multiple second reinforcing ribs 1131 can be provided, and along the left-right direction BB of the box body 10, multiple first reinforcing ribs 1122 are arranged in sequence on the bracket connecting plate 112, and multiple second reinforcing ribs 1131 are arranged in sequence on the top shell connecting plate 113, so as to further enhance the local strength of the bracket connecting plate 112 and the top shell connecting plate 113.

[0091] In some embodiments, two hooks 1121 are respectively arranged on the left and right sides of the first reinforcing rib 1122, ensuring uniform distribution of the force when the bracket connecting plate 112 installs the front panel 11, avoiding local stress concentration caused by uneven force. Due to the uniform force, the connection points between the front panel 11 and the motor bracket 20 are not prone to fatigue damage, thereby increasing the service life of the cabinet assembly 100. And two first mounting holes 11a are respectively arranged on the left and right sides of the whole formed by the two hooks 1121, making the installation of the front panel 11 simpler. The operator installs the hooks 1121 and the screw connectors 30 according to the preset hole positions, reducing the operation difficulty and installation time.

[0092] As Figure 6 and Figure 7 shown, in some embodiments, the front apron 122 includes an outer plate 1221 and an inward flange 1222. The outer plate 1221 is connected to the front edge of the main housing 121 at an angle. The inward flange 1222 is connected to one end of the outer plate 1221 away from the main housing 121 and is stacked on the side of the outer plate 1221 facing the top housing connecting plate 113. The stacking of the inward flange 1222 and part of the outer plate 1221 can provide additional structural strength. The inward flange 1222 can eliminate the tolerances generated during the manufacturing and assembly of the top housing 12. On the other hand, it can make the transition between the front apron 122 and the main board 111 smoother, improving the fit between the front apron 122 and the main board 111.

[0093] Among them, in the up-down direction DD of the cabinet 10, that is, in the height direction, the inward flange 1222 is located below the second reinforcing rib 1131, and the projection of the inward flange 1222 overlaps with part of the second reinforcing rib 1131. That is, in the vertical direction, the top housing 12 and the front panel 11 form a certain interference, which helps to enhance the connection strength between the front apron 122 and the top housing connecting plate 113 after the top housing 12 is installed, reducing the risk of the top housing 12 falling off due to vibration or impact during transportation.

[0094] Please refer to Figure 1 、 Figure 3 and Figure 6 ., in some embodiments, an outdoor unit 1 is further provided. The outdoor unit 1 includes a motor 200, an impeller 300, and the cabinet assembly 100 in any of the above embodiments. Among them, the motor 200 is arranged on the motor bracket 20, the impeller 300 is connected to the output shaft of the motor 200, and the motor 200 is used to drive the impeller 300 to rotate to generate air flow. And the front panel 11 has an air outlet 11b corresponding to the impeller 300. When the impeller 300 rotates, the hot air inside the outdoor unit 1 is sucked into the impeller 300. After being accelerated by the impeller 300, the hot air is accelerated and discharged outdoors, thereby helping the condenser dissipate heat and improving the refrigeration or heating efficiency. Ensuring the air circulation inside the outdoor unit 1 helps to keep the indoor and outdoor air fresh and comfortable.
