[0057] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0058] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0059] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0060] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0061] like Figures 1 to 8 As shown, according to an embodiment of this application, an outdoor unit 100 for HVAC equipment is proposed, wherein the outdoor unit 100 includes fasteners, functional components 10 and base plate assembly 20.

[0062] A mounting position 23 is provided on the base plate assembly 20. This mounting position 23 is a preset position for installing functional components 10 (such as gas-liquid separators, oil separators, compressors, or heat exchangers). The mounting position 23 is located on the base plate assembly 20. The specific position of the mounting position 23 needs to be set in conjunction with other functional components of the outdoor unit 100. That is, by reasonably arranging the position of the mounting position 23, it is possible to accommodate the installation of other functional components, so as to achieve the goal of compact structure and high space utilization of the outdoor unit 100.

[0063] Mounting position 23 is set on base plate assembly 20. It can be set in the middle of base plate assembly 20 or in other positions of base plate assembly 20, such as corners or edges of base plate assembly 20.

[0064] The mounting position 23 is provided with a snap-fit ​​structure 221. The snap-fit ​​structure 221 is located on the side of the mounting position 23 facing other functional components or having other structures. The connection position between the base plate assembly 20 and the fastener is located on the side that avoids other functional components or other structures (such as the assembly operation side or the edge side of the base plate assembly 20).

[0065] In addition, the base plate assembly 20 is provided with a fixing structure (the number of fixing structures can be one or more (two or more)). The fixing structure is set on the side of the base plate assembly 20 away from the mounting position 23. The fixing structure is used to fix the base plate assembly 20 to the mounting position 23 of the outdoor unit 100. The fixing structure can be a support foot. The support foot is fixed to the mounting position 23 of the outdoor unit 100 by expansion screws, etc. In this way, the outdoor unit 100 can be fixedly installed.

[0066] Functional component 10 is a component that provides corresponding functions for the operation of outdoor unit 100 (it can be a compressor, gas-liquid separator, oil separator, or heat exchanger, etc.). Functional component 10 includes a functional body 11 and bases 12, wherein the bases 12 are connected to the functional body 11, and there are multiple bases 12, which are spaced apart along the circumferential direction of the functional body 11. For example, if the component is a high-efficiency tank, the functional body 11 is the tank body of the high-efficiency tank, and the bases 12 are arranged along the circumference of the tank body and are respectively connected and fixed to the tank body.

[0067] The main body 11 is fixed to the base plate assembly 20 by the feet 12, that is, the feet 12 support the main body 11, thus realizing the installation of the main body 11. At the same time, the feet 12 space the main body 11 from the base plate assembly 20, and the feet 12 can isolate the vibration generated by the main body 11. In this way, the vibration transmitted from the main body 11 to the base plate assembly 20 can be reduced, thereby realizing vibration reduction and noise reduction of the outdoor unit 100, and thus improving the comfort of users during use.

[0068] Multiple feet 12 are spaced apart along the circumference of the functional body 11. The spacing can be equal or unequal. For example, if multiple feet 12 are spaced apart along the circumference of the functional body 11, the stability of the feet 12 supporting the functional body 11 can be improved, and the occurrence of swaying or even tipping of the functional body 11 due to uneven force can be reduced.

[0069] In this application, the number of the base 12 of the functional component 10 is multiple, specifically two, three, four, five, six, seven or eight, etc.

[0070] When the functional component 10 is assembled with the base plate body 21, a first number of the multiple feet 12 of the functional component 10 (the number is less than the total number of feet 12, and can be one, two, three, four, five, six or seven, etc.) of feet 12 are engaged with the snap-fit ​​structure 221 on the base plate assembly 20 by snap-fit, and a second number of feet 12 (the sum of the second number and the first number is equal to the total number of feet 12) of feet 12 are connected and fixed to the base plate assembly 20 by fasteners.

[0071] In the outdoor unit 100 of this application, a snap-fit ​​structure 221 is provided on the base plate assembly 20. The snap-fit ​​structure 221 can be installed in a confined space on the base plate assembly 20. During the assembly of the functional component 10, a number of the feet 12 of the functional component 10 are snapped into the snap-fit ​​structure 221, and the remaining feet 12 are connected to the base plate assembly 20 by fasteners. This reduces the limitations of confined space on assembly, thereby improving the convenience of assembly and increasing production efficiency.

[0072] It should be understood that in this application, the snap-fit ​​structure 221 and the base 12 can be snap-fitted together. Specifically, the snap-fit ​​structure 221 can be a slot 2211, a hole, or a buckle.

[0073] It should be noted that the base plate assembly 20 has a certain structural strength. The base plate assembly 20 is the carrier for mounting the functional component 10. The base plate assembly 20 can be a metal component or a non-metal component.

[0074] For example, the base plate assembly 20 is a metal component, which provides sufficient structural strength and reduces the possibility of damage to the functional component 10 due to deformation. The base plate assembly 20 can be an integral structure or a split structure. When the base plate assembly 20 is a metal component, it can be manufactured by stamping or other methods, thereby improving the ease of processing.

[0075] In this application, the outdoor unit 100 includes a housing, the base plate assembly 20 is a part of the housing structure, the housing also includes an outer cover, the outer cover is connected to the base plate assembly 20 and encloses an accommodating space, the functional components 10 and pipelines are arranged in the accommodating space, by utilizing the accommodating space to reduce the adverse effects of external factors on the functional components 10 and pipelines, thereby reducing the failure rate of the outdoor unit 100.

[0076] In some embodiments of this application, such as Figures 1 to 3 As shown, the base plate assembly 20 includes a connecting plate 22 and a base plate body 21. The connecting plate 22 is fixed on the base plate body 21. The base plate body 21 is used to be installed at a fixed position of the outdoor unit 100 and is used to be fixedly connected to the fixed position. The functional component 10 is fixed on the connecting plate 22. When the functional component 10 is fixed to the connecting plate 22, a portion of the bottom feet 12 of the functional component 10 are snapped and fixed to the connecting plate 22. The other portion of the bottom feet 12 of the functional component 10 are connected and fixed to the connecting plate 22 by fasteners.

[0077] The connecting plate 22 and the base plate body 21 are stacked along the height direction of the outdoor unit 100. The connecting plate 22 has a projection on the base plate body 21. The projection is within the area of ​​the base plate body 21, that is, the volume of the connecting plate 22 is smaller than the volume of the base plate body 21.

[0078] It is important to understand that the outdoor unit 100 can be cylindrical or polygonal. The axial direction of the cylinder or polygonal prism is the height direction of the outdoor unit 100. This can also be understood as the direction in which the outdoor unit 100 is aligned with the vertical direction after installation.

[0079] The base plate assembly 20 is configured as a two-part structure consisting of a connecting plate 22 and a base plate body 21, which makes the processing more convenient and improves the ease of processing, thereby increasing processing efficiency. At the same time, the layered structure formed by multiple plates in the base plate assembly 20 can improve the overall structural strength of the base assembly, thereby further enhancing the deformation resistance of the base assembly.

[0080] It should be noted that the connection method between the connecting plate 22 and the base plate body 21 includes, but is not limited to, at least one of the following connection methods: snap-fit, welding, and connector connection.

[0081] For example, the connecting plate 22 and the base plate body 21 are connected by a connector. After the two are processed independently, the connecting plate 22 is set in a preset position on the base plate body 21, and fasteners (such as screws or rivets) are connected to the connecting plate 22 and the base plate body 21 respectively, thus realizing the connection and fixation between the connecting plate 22 and the base plate body 21. By setting the connecting plate 22 and the base plate body 21 to be connected by a connector, the connecting plate 22 and the base plate body 21 can be separated by disengaging the connector from the connection between the connecting plate 22 and the base plate body 21. This facilitates the individual maintenance or replacement of the connecting plate 22 and the base plate body 21, thereby reducing the maintenance cost of the outdoor unit 100.

[0082] For example, the connecting plate 22 and the base plate body 21 are connected by welding. After the two are processed independently, the connecting plate 22 is set in a preset position on the base plate body 21. The connection and fixation between the connecting plate 22 and the base plate body 21 are achieved by using welding equipment. By setting the connecting plate 22 and the base plate body 21 as a welded connection, the structural strength of the connection position can be improved, and the structural strength and stability of the base plate assembly 20 can be effectively improved.

[0083] In addition, both the base plate body 21 and the connecting plate 22 are plate-shaped parts. The plate-shaped parts are formed into an assembly structure by stamping. During the stamping process, concave and convex shapes are formed on the surface of the plate, which can improve the structural strength of the plate and reduce the deformation of the base plate assembly 20 caused by the shaking of the functional parts 10.

[0084] In this application, the installation direction of the functional component 10 can be either vertical or horizontal.

[0085] Vertical installation means that the functional component 10 is positioned close to the base assembly in the height direction of the outdoor unit 100, so that the feet 12 of the functional component 10 are in contact with the base plate assembly 20, and a number of the feet 12 are snapped and fixed to the base assembly, while a number of the feet 12 are connected and fixed to the base assembly by fasteners.

[0086] Horizontal installation means that when the base assembly of the outdoor unit 100 is placed on the assembly table, the functional component 10 is moved in a direction parallel to the assembly table so that the functional component 10 reaches the installation position, and a number of the feet 12 are snapped and fixed to the base assembly, and a number of the feet 12 are connected and fixed to the base assembly by fasteners.

[0087] In some embodiments of this application, such as Figure 2 and Figure 8 As shown, the snap-fit ​​structure 221 is disposed on the connecting plate 22 of the base plate assembly 20. The snap-fit ​​structure 221 includes a slot 2211, and there is at least one slot 2211. The slot 2211 includes an opening, and the opening direction is parallel to the connecting plate 22. Wherein, the opening direction is parallel to the connecting plate 22, which means that the direction of entering or leaving the slot 2211 through the opening is parallel to the connecting plate 22.

[0088] When assembling the functional component 10, the foot 12 that mates with the snap-fit ​​structure 221 is positioned toward the opening of the slot 2211. By translating the functional component 10, the foot 12 is brought closer to the opening of the slot 2211 and snaps into the slot 2211 through the opening. After the foot 12 is snapped into place in the slot 2211, the slot 2211 limits the foot 12 in a direction perpendicular to the connecting plate 22, and the bottom of the slot 2211 limits the foot 12 in a direction parallel to the connecting plate 22. Then, the remaining feet 12 (foot 12 fixed by fasteners) are connected and fixed to the connecting plate 22 using fasteners.

[0089] By setting the snap-fit ​​structure 221, the functional component 10 can be assembled in a direction parallel to the connecting plate 22, reducing the need to lift the functional component 10 in a direction perpendicular to the connecting plate 22 during the assembly process, thereby improving the convenience of assembly and effectively improving the efficiency of assembly.

[0090] It should be understood that the card slot 2211 can be a C-shaped slot, that is, the opening of the card slot 2211 is set to face the horizontal direction.

[0091] It should be noted that the number of slots 2211 can be one, two, three, four, five, or six. When there are multiple slots 2211 (two or more), the snapping direction of the multiple slots 2211 is consistent. This facilitates the simultaneous engagement of the base 12 with the multiple slots 2211 during the assembly of the functional component 10, enabling the assembly to be carried out smoothly.

[0092] In some embodiments of this application, such as Figure 2 and Figure 8 As shown, a protruding structure is formed on the connecting plate 22. The protruding structure is formed on the side of the connecting plate 22 facing the functional body 11 of the functional component 10. The protruding structure has a side wall, which is the outer peripheral wall of the protruding structure. A notch is provided on the outer peripheral wall, which constitutes the snap-fit ​​structure 221 of the slot 2211.

[0093] Specifically, the notch is made on the side wall of the raised structure, and the depth direction of the notch is parallel to the connecting plate 22 of the base plate assembly 20.

[0094] It should be understood that, along the circumferential direction of the protruding structure, the notch covers at least part of the circumferential area of ​​the protruding structure. In this way, the opening of the slot 2211 can have a larger coverage area, thereby improving the ease with which the base 12 can be inserted into the slot 2211 during the assembly process, further reducing the difficulty of assembly, and improving the efficiency of assembly.

[0095] When assembling the functional component 10, the foot 12 that mates with the snap-fit ​​structure 221 is positioned toward the opening of the slot 2211. By translating the functional component 10, the foot 12 is brought closer to the opening of the slot 2211 and snaps into the slot 2211 through the opening. After the foot 12 is snapped into place in the slot 2211, the slot 2211 limits the foot 12 in a direction perpendicular to the connecting plate 22, and the bottom of the slot 2211 limits the foot 12 in a direction parallel to the connecting plate 22. Then, the remaining feet 12 (foot 12 fixed by fasteners) are connected and fixed to the connecting plate 22 using fasteners.

[0096] The simple structure formed by the card slot 2211 can effectively reduce the manufacturing cost of the base plate assembly 20, thereby effectively reducing the manufacturing cost of the outdoor unit 100.

[0097] The connecting plate 22 has a protruding structure on the side facing the functional body 11. Along the circumferential direction of the protruding structure, a notch is provided on the side wall of the mounting position 23, and the notch forms a slot 2211.

[0098] It should be noted that the notch is set on the side wall of the protruding structure. The notch can be processed and manufactured simultaneously with the protruding structure, or it can be formed by post-processing on the protruding structure after the protruding structure has been processed and manufactured.

[0099] In addition, the protruding structure can be integrally formed with the connecting plate 22, or it can be processed separately and fixed on the connecting plate 22.

[0100] In some embodiments of this application, such as Figure 8 As shown, the protruding structure is integrally formed with the connecting plate 22. The connecting plate 22 is set on a stamping machine and stamped by the stamping machine, so that one side of the connecting plate 22 is concave and the other side is convex, thereby forming a protruding structure. This setting can improve the convenience of processing and reduce the processing cost.

[0101] In addition, the protruding structure is integrally formed with the connecting plate 22, and the overall structural strength is stable, which can improve the strength and stability of the overall structure of the connecting plate 22.

[0102] It should be noted that the protruding structure is formed on the connecting plate 22 by stamping. During the stamping process, the mold of the stamping equipment stamps the connecting plate 22, causing one side of the connecting plate 22 to be concave and the other side to be convex. The protruding side breaks off from part of the edge of the connecting plate 22, while the other part remains connected. The break point forms a notch in the protruding structure, thus forming the slot 2211. In this way, the processing and manufacturing of the snap-fit ​​structure 221 can be effectively realized.

[0103] In some embodiments of this application, such as Figure 8 As shown, the snap-fit ​​structure 221 is disposed on the connecting plate 22 of the base plate assembly 20. The snap-fit ​​structure 221 is configured as a slot 2211. The number of slots 2211 can be one or more.

[0104] When there are multiple slots 2211, multiple slots 2211 are spaced apart along the circumferential direction of the mounting position 23 (i.e., the location of the connecting plate 22), and multiple slots 2211 are spaced apart in the first circumferential region of the mounting position 23 (the length of the first circumferential region is less than the entire circumferential length of the mounting position 23).

[0105] It should be understood that the first circumferential area is a portion of the circumferential area of ​​the mounting position 23, and multiple slots 2211 are spaced apart within the first circumferential area. When installing the functional component 10, the functional component 10 can be positioned on the side of the mounting position 23 opposite to the first circumferential area, and the base 12 can be engaged and fixed with the slot 2211. This allows the base 12 to be smoothly inserted into the slot 2211, improving the ease of assembly.

[0106] The functional component 10 has multiple feet 12. When the functional component 10 is installed, all the slots 2211 can engage with the feet 12 (each slot 2211 corresponds to one foot 12), or only a portion of the slots 2211 can engage with the feet 12 (i.e., some feet 12 are unused). By setting the number and arrangement of the feet 12, the connecting plate 22 with slots 2211 can adapt to the installation requirements of different functional components 10 (the number of feet 12 in the functional component 10 may vary), thereby improving the versatility of the connecting plate 22.

[0107] It should be understood that the number of card slots 2211 can be less than, equal to, or greater than the number of base pins 12 of the functional component 10. Specifically, the number of card slots 2211 can be two, three, four, five, six, seven, eight, nine, ten, etc.

[0108] In some embodiments of this application, a connecting structure 222 is provided on the connecting plate 22. The connecting structure 222 is used to connect and cooperate with fasteners so that the foot 12 is connected to the connecting structure 222 through the fasteners, thereby realizing the connection and fixation of the foot 12 and the base plate assembly 20.

[0109] The connecting structure 222 can be a connecting hole or a connecting post, etc.

[0110] For example, the connecting structure 222 is a connecting hole, and the number of connecting holes is at least one. When the functional component 10 is assembled, the foot 12 that mates with the snap-fit ​​structure 221 is positioned towards the opening of the snap-fit ​​groove 2211 of the snap-fit ​​structure 221. By translating the functional component 10, the foot 12 is brought close to the opening of the snap-fit ​​groove 2211 and snaps into the snap-fit ​​groove 2211 through the opening of the snap-fit ​​groove 2211. After the foot 12 is snapped into place in the snap-fit ​​groove 2211, the snap-fit ​​groove 2211 limits the foot 12 in a direction perpendicular to the connecting plate 22, and the bottom of the snap-fit ​​groove 2211 limits the foot 12 in a direction parallel to the connecting plate 22. Then, a fastener passes through the foot 12 (the foot 12 fixed by the fastener) and connects it to the connecting hole on the connecting plate 22.

[0111] The fastener can be a screw or a rivet. When the fastener is a rivet, after the rivet passes through the connecting hole, the rivet is deformed by the riveting setting to connect and fix the connecting plate 22 to the connecting plate 22.

[0112] It should be noted that the number of connection holes can be one, two, three, four, five, six, seven, eight, nine, ten, etc.

[0113] In some embodiments of this application, such as Figure 8 As shown, there are multiple connection holes on the connection plate 22 of the base plate assembly 20.

[0114] When there are multiple connecting holes, the multiple connecting holes are spaced apart along the circumferential direction of the mounting position 23 (i.e., the position where the connecting plate 22 is located), and the multiple connecting holes are spaced apart in the second circumferential region of the mounting position 23 (the length of the second circumferential region is less than the entire circumferential length of the mounting position 23, and the second circumferential regions are arranged sequentially).

[0115] It should be understood that the second circumferential region is a portion of the circumferential area of ​​the mounting position 23, and multiple connecting holes are spaced apart within the second circumferential region. When installing the functional component 10, the functional component 10 can be positioned onto the mounting position 23 from one side of the second circumferential region, and the base 12 can be engaged and fixed with the slot 2211. This allows the base 12 to be smoothly inserted into the slot 2211, thereby improving the ease of assembly.

[0116] It should be understood that the number of connecting holes is less than the number of feet 12 of the functional component 10. The specific number of connecting holes can be two, three, four, five, six, seven, eight, nine, ten, etc.

[0117] In some embodiments of this application, the connecting hole is a threaded hole, the fastener is a screw, and the threaded section of the screw passes through the base 12 and is threadedly connected to the threaded hole.

[0118] Specifically, when the fastener is a screw, the connecting hole is threadedly connected to the screw, thus facilitating the disassembly of the fastener. When the fastener is a rivet, after the rivet passes through the connecting hole, the rivet is deformed by the riveting mechanism to connect and fix the connecting plate 22 to the connecting plate 22.

[0119] In some embodiments of this application, such as Figure 2 , Figure 5 and Figure 6 As shown, the base 12 includes a main body 121 and a support plate 122, and the number of support plates 122 is at least two.

[0120] Specifically, all support plates 122 are arranged on the same side of the main body 121, with adjacent support plates 122 spaced apart. The main body 121 is used to cooperate with the snap-fit ​​structure 221 or to be connected to the base plate via fasteners. Each support plate 122 is provided with a support surface 1221, and the functional body 11 of the functional component 10 abuts against the support surface 1221, with the functional body 11 connected to the support surface 1221.

[0121] Multiple support plates 122 simultaneously support the functional body 11, thereby increasing the strength of the support, reducing the possibility of insufficient support strength of the base 12, and thus improving the stability of the functional body 11 structure.

[0122] It should be understood that the support plate 122 is perpendicular to the main body 121, and the supporting surface 1221 is formed on the top of the support plate 122. The support structure formed by the main body 121 and multiple support plates 122 has high structural strength and can provide better support for the functional component 10.

[0123] In addition, two adjacent support plates 122 can be set in parallel or not.

[0124] It should be noted that the number of support plates 122 can be two, three, four, five, six, seven, eight, nine, ten, etc.

[0125] In addition, a through hole 1211 is provided on the main body 121 for fasteners to pass through. The through hole 1211 can be a circular hole, an elliptical hole or a polygonal hole.

[0126] For example, the through hole 1211 is an oblong hole. This design makes it easy to adjust the position of the foot 12, thereby meeting the installation requirements of functional components 10 of different specifications.

[0127] In addition, the support plate 122 and the main body 121 can be an integral structure or a separate structure connected together.

[0128] For example, the support plate 122 and the main body 121 are an integral structure. The integral structure is manufactured by stamping or casting. On the one hand, it can reduce the number of processing steps and improve the processing efficiency. On the other hand, the overall structural strength of the integral structure can further improve the strength of supporting the main body 11, thereby improving the structural stability of the entire functional component 10.

[0129] Furthermore, the connection between the supporting surface 1221 and the functional body 11 is by welding. Welding has high structural strength and can improve the structural stability between the base 12 and the functional body 11.

[0130] In some embodiments of this application, such as Figure 2 , Figure 5 and Figure 6 As shown, the support plate 122 also includes an abutment surface 1222 connected to the support surface 1221. The abutment surface 1222 and the support surface 1221 form an L-shaped structure. The outer peripheral wall of the functional body 11 abuts against the abutment surface 1222 and is connected to the abutment surface 1222.

[0131] The abutment surface 1222 can limit the functional body 11 on the outer periphery of the functional body 11. The abutment surface 1222 and the support surface 1221 are respectively connected to the functional body 11, and can limit and connect the functional body 11 from different directions. In this way, the structural strength of the connection position is improved, and the overall structural stability of the functional component 10 is improved.

[0132] In some embodiments of this application, the edge of the connecting plate 22 is provided with a flange structure. When the connecting plate 22 is connected to the base plate body 21, the flange structure abuts against the base plate body 21, so that the connecting plate 22 and the base plate body 21 are spaced apart.

[0133] Specifically, such as Figure 2 As shown, a through hole 223 is provided on the connecting plate 22, and the area between the connecting plate 22 and the base plate body 21 can be connected to the outside through the through hole 223.

[0134] To improve the corrosion resistance of the base plate assembly 20, anti-corrosion materials (such as anti-corrosion paint) are sprayed onto the base plate body 21 and the connecting plate 22. The anti-corrosion material forms an anti-corrosion layer on the surface of the base plate body 21 and the connecting plate 22, thereby improving the corrosion resistance of the base plate body 21 and the connecting plate 22 and extending their service life.

[0135] The base plate body 21 and the connecting plate 22 can be coated with anti-corrosion materials before assembly, that is, the base plate body 21 and the connecting plate 22 are coated with anti-corrosion materials before assembly.

[0136] The base plate body 21 and the connecting plate 22 can also be coated with anti-corrosion materials after assembly. That is, the base plate body 21 and the connecting plate 22 are assembled first, and then the assembled structure is coated with anti-corrosion materials.

[0137] In this application, the base plate body 21 and the connecting plate 22 are also coated with anti-corrosion material after assembly. A through hole 223 is provided on the connecting plate 22, which communicates with the area between the connecting plate 22 and the base plate body 21. When anti-corrosion material is to be applied, it can enter the area between the connecting plate 22 and the base plate body 21 through the through hole 223, thereby improving the coating effect and reducing rust and corrosion on the base plate body 21 and the connecting plate 22, thus extending the service life of the base plate assembly 20.

[0138] In some embodiments of this application, such as Figure 2 As shown, the functional body 11 has a first projection 24 on the connecting plate 22, and the through hole 223 is opened in the area where the first projection 24 is located.

[0139] It should be understood that the base 12 of the functional component 10 has a connection position with the connecting plate 22. The greater the distance between the through hole 223 and the connection position, the better the structural stability of the functional component 10. Conversely, the greater the distance between the through hole 223 and the connection position, the worse the structural stability of the functional component 10.

[0140] In this application, a through hole 223 is provided between the functional body 11 and the base plate body 21 along a direction perpendicular to the base plate body 21. By placing the through hole 223 within the range of the first projection 24 of the functional body 11 on the connecting plate 22, the through hole 223 avoids the position of the bottom foot 12 of the functional component 10, thereby reducing the impact of the through hole 223 on the overall structural strength of the connecting plate 22, and thus enabling the connecting plate 22 to provide better support performance for the functional component 10.

[0141] It should be noted that the shape of the through hole 223 can be the same as or different from the shape of the first projection 24.

[0142] In some embodiments of this application, such as Figure 2 , Figure 3 and Figure 8 As shown, the first projection 24 is a circular projection, and the through hole 223 is a circular hole. The first projection 24 and the through hole 223 are concentrically arranged.

[0143] Specifically, by setting the shapes of the first projection 24 and the through hole 223, the structural distribution of the functional body 11 on the radial outer side of the through hole 223 can be uniform, so that the structural strength of the connecting plate 22 can effectively support the functional component 10, thereby further improving the structural stability of the functional component 10.

[0144] In some embodiments of this application, the ratio of the area of ​​the through hole 223 to the area of ​​the first projection 24 is in the range of 0.3 to 0.8.

[0145] Specifically, by setting the ratio of the area of ​​the through hole 223 to the area of ​​the first projection 24, the connecting plate 22 can, while providing better support for the functional component 10, control the opening area of ​​the through hole 223 to the optimal level, so that the anti-corrosion material can better enter the area between the connecting plate 22 and the base plate body 21 through the through hole 223, thereby improving the anti-corrosion performance of the base plate body 21 and the connecting plate 22.

[0146] It should be noted that the ratio of the area of ​​the through hole 223 to the area of ​​the first projection 24 can specifically be 0.3, 0.4, 0.5, 0.6, 0.7, or 0.8.

[0147] like Figures 1 to 8 As shown, the second aspect of this application proposes a heating, ventilation and air conditioning (HVAC) device, which includes an outdoor unit 100 and an indoor unit. The outdoor unit 100 is an outdoor unit 100 as described above, and the indoor unit is connected to the outdoor unit 100 to form a refrigerant circulation path.

[0148] In the outdoor unit 100 of the HVAC equipment of this application, a snap-fit ​​structure 221 is provided on the base plate assembly 20. The snap-fit ​​structure 221 can be installed in confined spaces within the base plate assembly 20. During the assembly of the functional component 10, a portion of the base feet 12 of the functional component 10 are snapped into place with the snap-fit ​​structure 221, while the remaining base feet 12 are connected to the base plate assembly 20 by fasteners. This reduces the limitations of confined spaces on assembly, thereby improving assembly convenience and increasing production efficiency.

[0149] In this application, the aforementioned HVAC equipment can be a household air conditioner, etc. The structure of other parts of this HVAC equipment can be found in existing technology and will not be described in detail here. The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
