Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more specifically, to a mounting base and an outdoor air conditioning unit. Background Technology

[0002] The support components of an air conditioner outdoor unit typically include a chassis and three feet spaced apart at the bottom of the chassis. However, because the chassis needs to be stamped with mounting parts to support various components, its sheet metal structure is complex. Therefore, the three feet located in different installation areas need to be press-formed according to the sheet metal structure of the base plate in their respective installation areas to ensure a tight fit and stable connection. This results in each area of ​​the base plate requiring a foot being manufactured separately to match it, increasing mold costs and causing poor parts interchangeability, which is inconvenient for management. Utility Model Content

[0003] This application provides a mounting base and an outdoor air conditioning unit to solve at least one of the aforementioned technical problems.

[0004] The foot in this embodiment is used for an outdoor air conditioner unit. The outdoor air conditioner unit includes a chassis for mounting a refrigeration component. The bottom surface of the chassis has multiple mounting areas. A mounting portion for mounting the refrigeration component is stamped on the surface of the chassis near the refrigeration component. Multiple first positioning portions are formed in each of the multiple mounting areas. The foot includes:

[0005] The main body is provided with a second positioning part, which is configured such that when the main body is installed in any of the installation areas of the chassis, the second positioning part cooperates with the corresponding first positioning part.

[0006] The foot provided in this application, by setting a second positioning part on the main body that can cooperate with various first positioning parts, enables a single type of foot to adapt to the installation requirements of different molding areas of the chassis, improves the versatility of the foot, helps to reduce management costs and mold opening costs, and reduces management difficulty.

[0007] In some embodiments, the first positioning part is a positioning boss, and the second positioning part is a positioning groove that mates with the positioning boss.

[0008] In this way, the boss can be integrally formed with the chassis through processes such as stamping and casting, and the groove can also be directly formed by sheet metal stamping or molds, without the need for additional drilling or tapping processes, thus reducing manufacturing costs.

[0009] In some embodiments, the positioning groove is a groove that at least partially surrounds the positioning boss, so that when the positioning groove mates with the positioning boss, at least a portion of the inner sidewall of the positioning groove fits against the outer sidewall of the positioning boss.

[0010] This helps to achieve precise positioning and avoids the risk of displacement between the feet and the chassis due to loose bolts or assembly gaps.

[0011] In some embodiments, the edge of the positioning groove is provided with a guide portion.

[0012] In this way, the guide section facilitates the engagement of the positioning boss and the positioning groove.

[0013] In some embodiments, the foot further includes a fixing part for connecting to a mounting plane, the fixing part being disposed at the end of the body and extending from the bottom of the chassis when the body is mounted on the chassis.

[0014] In this way, the fixing part extends from the bottom of the chassis, making it easy to fix the outdoor unit of the air conditioner.

[0015] In some embodiments, the foot is further provided with reinforcing ribs, which are disposed at the connection between the main body and the fixing part.

[0016] Therefore, adding reinforcing ribs helps to improve the structural strength of the base.

[0017] In some embodiments, the installation area is provided with bolt holes for fixing other components of the outdoor unit of the air conditioner, and the surface of the main body near the chassis is recessed to form a clearance portion that mates with the bolt holes.

[0018] Therefore, setting up a clearance part can avoid interference with the bolts during installation, ensuring a smooth installation process.

[0019] In some embodiments, a first drainage hole is provided in the installation area, and a second drainage hole corresponding to the first drainage hole is provided on the main body.

[0020] Therefore, by setting a second drain hole corresponding to the first drain hole, the water accumulated in the chassis can be drained in time, preventing the water from damaging the outdoor unit of the air conditioner.

[0021] In some embodiments, the main body is further provided with a first welding positioning hole, and the mounting area is provided with a second welding positioning hole that cooperates with the first welding positioning hole.

[0022] Thus, the first and second welding positioning holes can be used for welding positioning, allowing the foot and base plate to be connected by welding to further enhance the stability of the connection.

[0023] Another embodiment of the air conditioner outdoor unit of this application includes the foot as described in any of the above claims.

[0036] The support components of an air conditioner outdoor unit typically include a chassis and three feet spaced apart at the bottom of the chassis. However, because the chassis needs to be stamped with mounting parts to support various components, its sheet metal structure is complex. Therefore, the three feet located in different installation areas need to be press-formed according to the sheet metal structure of the base plate in their respective installation areas to ensure a tight fit and stable connection. This results in each area of ​​the base plate requiring a foot being manufactured separately to match it, increasing mold costs and causing poor parts interchangeability, which is inconvenient for management.

[0037] Please see Figures 1 to 3 This application provides a foot 10 for an outdoor air conditioner unit. The outdoor air conditioner unit includes a chassis 20 for mounting a refrigeration component. The bottom surface of the chassis 20 is provided with a plurality of mounting areas 21. Mounting portions 22 for mounting the refrigeration component are stamped on the surface of the chassis 20 near the refrigeration component. A plurality of first positioning portions 23 are formed in the plurality of mounting areas 21 respectively. The outdoor air conditioner unit also includes a foot 10. The foot 10 includes a main body 11. The main body 11 is provided with a second positioning portion 111. The second positioning portion 111 is configured such that when the main body 11 is installed in any mounting area 21 of the chassis 20, the second positioning portion 111 cooperates with the corresponding first positioning portion 23.

[0038] In some embodiments, an outdoor air conditioning unit is also provided, which includes a chassis 20 and the aforementioned foot 10.

[0039] The foot 10 provided in this application, by providing a second positioning part 111 on the main body 11 that can cooperate with various first positioning parts 23, enables a single type of foot 10 to adapt to the installation requirements of different molding areas of the chassis 20, thereby improving the versatility of the foot 10, reducing management costs and mold opening costs, and reducing management difficulty.

[0040] Please see Figure 2 and Figure 5Specifically, the base plate is a crucial supporting structure for the outdoor unit of the air conditioner, primarily responsible for bearing the weight of the equipment, protecting the internal refrigeration components, and providing stability. In this embodiment, the base plate includes a main chassis 24 and an extension chassis 25, both of which are integrally formed structures. The chassis 20 is typically made of rust-resistant galvanized steel, stainless steel, or lightweight aluminum alloy. Depending on the model, metal sheets of 1.2–2.0 mm thickness are usually selected. The metal sheets are stamped into specific shapes using molds. Complex structures require bending before welding, ensuring smooth and strong welds to avoid stress concentration. This not only ensures high efficiency and good structural consistency but also guarantees load-bearing capacity and resistance to deformation.

[0041] Furthermore, the main chassis 24 has a first through hole on its main side wall, and the extension chassis 25 has a corresponding second through hole on its side wall. When the extension chassis 25 is connected to the main chassis 24, the first and second through holes are aligned and then secured with fasteners. This increases the strength of the connection and prevents loosening or separation due to vibration during long-term use. Simultaneously, the fasteners provide more reliable fixation, suitable for use in harsh environments or under high load conditions. In addition, it may improve the overall structural stability and reduce noise and vibration.

[0042] It is important to note that when the extension chassis 25 is installed, the first and second through holes must be aligned. Inaccurate hole alignment will cause installation difficulties. The structural strength around the first and second through holes must be sufficient to prevent cracking during installation. Rust prevention treatment is also necessary, especially on fasteners and the area around the first and second through holes, to prevent corrosion that could hinder disassembly.

[0043] In this embodiment, rivets are selected as the fasteners; that is, rivets are used to pass through the first through hole and the second through hole to rivet the main chassis 24 and the extension chassis 25 together. Since this method requires destroying the rivets during disassembly, this connection method is suitable for situations where the main chassis 24 and the extension chassis 25 need to be connected for a long time and there are few opportunities for disassembly.

[0044] In other embodiments, the fasteners may also be mating bolts and nuts. It should be noted that the bolts must be long enough to pass through both holes and have sufficient thread engagement length.

[0045] In this embodiment of the application, three installation areas 21 are provided on the bottom surface of the chassis 20. Two installation areas 21 are located on both sides of the bottom surface of the chassis 20, and the last installation area 21 is located at the connection between the main chassis 24 and the extended chassis 25, so as to prevent the main chassis 24 and the extended chassis 25 from separating due to the gravity of other components in the outdoor unit of the air conditioner.

[0046] The three mounting areas 21 on the bottom surface of the chassis 20 can also be arranged in other ways. For example, the three mounting areas 21 can be set under the heaviest component inside the outdoor unit of the air conditioner.

[0047] In this embodiment, the chassis 20 is provided with multiple mounting portions 22 to support the refrigeration components inside the outdoor unit of the air conditioner. Furthermore, since the chassis 20 is a one-piece stamped sheet metal part, the mounting portions 22 are usually also formed by one stamping process for ease of processing. Optionally, the mounting portions 22 are formed by protruding from the surface of the chassis 20 near the refrigeration components toward the refrigeration components, or the mounting portions 22 are formed by recessing from the surface of the chassis 20 near the refrigeration components toward the direction away from the refrigeration components. Alternatively, the mounting portions 22 may be hole-shaped or groove-shaped structures penetrating the chassis 20.

[0048] Please see Figure 1 and Figure 2 Correspondingly, when the surface of the chassis 20 near the refrigeration component protrudes in the direction of the refrigeration component to form the mounting part 22, a first positioning part 23 recessed towards the inside of the outdoor unit of the air conditioner is formed in the mounting area 21; when the surface of the chassis 20 near the refrigeration component is recessed in the direction away from the refrigeration component to form the mounting part 22, a first positioning part 23 protruding towards the outside of the outdoor unit of the air conditioner is formed in the mounting area 21.

[0049] Since the cooling components on the top surface of the chassis 20 are not entirely the same in the three mounting areas 21, the structures of the mounting parts 22 in the three mounting areas 21 are also not entirely the same, which makes the first positioning parts 23 in the three mounting areas 21 also not entirely the same. The second positioning part 111 should simultaneously satisfy the requirement of being able to cooperate with the first positioning parts 23 in the three mounting areas 21.

[0050] In this embodiment, the foot 10 is also a sheet metal part formed by one-piece stamping.

[0051] Please see Figure 1 and Figure 2 In some embodiments, the first positioning part 23 is a positioning boss, and the second positioning part 111 is a positioning groove that cooperates with the positioning boss.

[0052] In this way, the boss can be integrally formed with the chassis 20 through processes such as stamping and casting, and the groove can also be directly formed by sheet metal stamping or mold, without the need for additional drilling or tapping processes, thus reducing manufacturing costs.

[0053] Specifically, in this embodiment, the surface of the chassis 20 near the refrigeration component is recessed in the direction away from the refrigeration component to form a mounting portion 22, and a positioning boss protruding outward toward the outdoor unit of the air conditioner is formed in the mounting area 21; further, the second positioning portion 111 is a positioning groove provided on the main body 11 and capable of simultaneously accommodating all the positioning bosses in the three mounting areas 21. Specifically, when the foot 10 is installed on any one of the mounting areas 21 of the chassis 20, the orthographic projection of all the positioning bosses in the mounting area 21 toward the positioning groove is located in the positioning groove.

[0054] In this embodiment of the application, preferably, the shape of the overlapping orthographic projections of all the positioning bosses in the three mounting areas 21 is the same as the shape of the positioning groove.

[0055] In other embodiments, the first positioning part 23 can be a positioning groove, and the second positioning part 111 can be a positioning boss on the main body 11 that can be simultaneously embedded in all the positioning grooves in the three mounting areas 21. That is, when the foot 10 is installed on any one of the mounting areas 21 of the chassis 20, the orthographic projection of the positioning boss toward the positioning groove is located in the positioning groove of the corresponding mounting area 21.

[0056] In other embodiments, the mounting portion 22 and the first positioning portion 23 may be configured with other suitable structures.

[0057] Please see Figures 1 to 5 In some embodiments, the positioning groove is a groove that at least partially surrounds the positioning boss, so that when the positioning groove mates with the positioning boss, at least a portion of the inner sidewall of the positioning groove fits against the outer sidewall of the positioning boss.

[0058] This helps to achieve precise positioning and avoids the risk of displacement between the foot 10 and the chassis 20 due to loose bolts or assembly gaps.

[0059] Specifically, in this embodiment, at least part of the inner wall of the positioning groove fits against the outer wall of the positioning boss, which can form a certain constraint between the foot 10 and the chassis 20, thereby limiting the relative displacement between the foot 10 and the chassis 20 and preventing the outdoor unit of the air conditioner from tilting due to the displacement of the foot 10.

[0060] In the embodiments of this application, please refer to Figure 1 and Figure 5The three installation areas 21 are designated as the first installation area 211, the second installation area 212, and the third installation area 213. The first installation area 211 contains a first positioning boss 231, a second positioning boss 232, and a third positioning boss 233. The second installation area 212 contains a fourth positioning boss 234, and the third installation area 213 contains a fifth positioning boss 235. The main body 11 has a first positioning groove 1111, a second positioning groove 1112, and a third positioning groove 1113. The first positioning groove 1111 is the same size and shape as the first positioning boss 231, the second positioning groove 1112 is the same size as the second positioning boss 232, and the third positioning groove 1113 is the same size and shape as the third positioning boss 233. The fourth positioning boss 234 and the fifth positioning boss 235 can mate with the third positioning groove 1113. That is, when the foot 10 is installed in the first installation area 211, the fourth positioning boss 231 and the fifth positioning boss 235 mate with the third positioning groove 2113. A positioning boss 231 is embedded in a first positioning groove 1111, and the outer side wall of the first positioning boss 231 is in contact with the inner side wall of the first positioning groove 1111. A second positioning boss 232 is embedded in a second positioning groove 1112, and the outer side wall of the second positioning boss 232 is in contact with the inner side wall of the second positioning groove 1112. A third positioning boss 233 is embedded in a third positioning groove 1113, and the outer side wall of the third positioning boss 233 is in contact with the inner side wall of the third positioning groove 1113. When the foot 10 is installed in the second mounting area 212, a fourth positioning boss 234 is embedded in the third positioning groove 1113, and part of the outer side wall of the fourth positioning boss 234 is in contact with the inner side wall of the third positioning groove 1113. When the foot 10 is installed in the third mounting area 213, a fifth positioning boss 235 is embedded in the third positioning groove 1113, and part of the outer side wall of the fifth positioning boss 235 is in contact with the inner side wall of the third positioning groove 1113.

[0061] In some embodiments, when the orthographic projections of all the positioning bosses in the three mounting areas 21 overlap, and the orthographic projection of any positioning boss in one mounting area 21 is completely within the orthographic projection of the positioning boss in another mounting area 21 without overlapping edges, for example, when the orthographic projection of the fourth positioning boss 234 in the second mounting area 212 is completely within the orthographic projections of the three positioning bosses in the first mounting area 211, in order to ensure the versatility of the foot 10, when the foot 10 is installed in the second mounting area 212, the inner sidewall of the positioning groove may not be in contact with the outer sidewall of the fourth positioning boss 234.

[0062] Please see Figure 4 In some embodiments, the edge of the positioning groove is provided with a guide portion 1114.

[0063] Thus, the guide part 1114 facilitates the engagement of the positioning boss and the positioning groove.

[0064] Specifically, in this embodiment, the guide portion 1114 at the edge of the positioning groove is a rounded corner. During the connection between the foot 10 and the chassis 20, when the positioning boss is inserted into the positioning groove, the rounded corner can play a guiding role, facilitating the installation between the foot 10 and the chassis 20. In addition, the rounded corner can also facilitate the demolding of the foot 10.

[0065] Furthermore, a guide portion 1114 may also be provided at the corner of the positioning boss, and the guide portion 1114 may also be provided as a transition fillet.

[0066] In some embodiments, the guide portion 1114 may also be configured as a chamfer or other structure with a guiding function, which can be selected according to actual needs, and will not be described in detail here.

[0067] In some embodiments, the foot 10 further includes a fixing part 12 for connecting to the mounting plane. The fixing part 12 is disposed at the end of the body 11 and extends from the bottom of the chassis 20 when the body 11 is mounted on the chassis 20.

[0068] Thus, the fixing part 12 extends from the bottom of the chassis 20, making it easy to fix the outdoor unit of the air conditioner.

[0069] Specifically, in this embodiment, the fixing part 12 includes a fixing plate 121 and a fixing groove 122 disposed on the fixing plate 121. The fixing part 12 can be fixed to the mounting surface by fasteners passing through the fixing groove 122. The semi-open fixing groove 122 allows the fasteners to move freely within the groove, allowing installation to be completed without precise alignment of the holes. In this way, it can adapt to different installation environments (such as uneven walls or differences in bracket dimensions), and the position can be quickly adjusted by sliding the fasteners, avoiding rework or structural deformation caused by mismatched holes. In addition, some nuts are designed to be directly inserted into the screw through a semi-circular slot, eliminating the need for gradual tightening and improving installation efficiency by more than 30%. At the same time, the groove design facilitates the deep access of disassembly tools (such as wrenches), shortening maintenance time.

[0070] Furthermore, the fixing plate 121 is also provided with a receiving groove, which surrounds the fixing groove 122. Thus, when the fastener is a rivet, bolt or screw, the receiving groove can be used to receive the end of the rivet or the nut of the bolt or screw.

[0071] In some embodiments, the fixing part 12 includes a fixing plate 121 and a fixing hole penetrating the fixing plate 121. In this case, the receiving groove can be arranged around the fixing hole. It should be noted that although the positioning of the fixing hole is more precise, setting it as a fixing hole may lead to more processing steps and increased costs. When choosing, the priority between precise positioning and cost and installation difficulty should be considered.

[0072] In some embodiments, the foot 10 is also provided with a reinforcing rib 13, which is located at the connection between the main body 11 and the fixing part 12.

[0073] Thus, the addition of reinforcing ribs 13 helps to improve the structural strength of the base 10.

[0074] Specifically, in this embodiment, there are two reinforcing ribs 13, both of which are located at the connection between the main body 11 and the fixing part 12, and are respectively located on both sides of the main body 11. Thus, the reinforcing ribs 13 form a "U"-shaped cross-section on the foot 10, which significantly improves the bending stiffness of the plate-like component. Furthermore, the formation of the reinforcing ribs 13 can enhance the bending strength of the chassis 20, while also reducing operating noise and adapting to complex installation environments.

[0075] In this embodiment, reinforcing ribs 13 located on both sides of the main body 11 are formed by stamping a groove in the middle of the connection between the main body 11 and the fixing part 12. In this way, the reinforcing ribs 13 can be stamped together with other structures during the processing of the foot 10, which helps to reduce processing difficulty and improve production efficiency.

[0076] Please see Figure 4 and Figure 5 In some embodiments, the mounting area 21 is provided with bolt holes 26 for fixing other components of the outdoor unit of the air conditioner, and the surface of the main body 11 near the chassis 20 is recessed to form a relief portion 14 that mates with the bolt holes 26.

[0077] Thus, the avoidance part 14 can prevent interference with the bolts during installation, ensuring smooth installation.

[0078] Specifically, in this embodiment, a gas-liquid separator and a compressor are mounted on the base plate. Both the gas-liquid separator and the compressor are detachably mounted on the base plate via bolts passing through bolt holes 26. Correspondingly, the clearance portion 14 includes a gas separator bolt clearance hole 141 for clearance of bolts fixing the gas-liquid separator and a compressor bolt clearance groove 142 for clearance of bolts fixing the compressor. When the foot 10 is mounted on the chassis 20, all bolts in the safety zone are located in the corresponding clearance portion 14.

[0079] In some embodiments, the installation area 21 is provided with a first drainage hole 214, and the main body 11 is provided with a second drainage hole 15 corresponding to the first drainage hole 214.

[0080] Thus, by setting a second drain hole 15 corresponding to the first drain hole 214, the water accumulated in the chassis 20 can be drained in time, preventing the water from damaging the outdoor unit of the air conditioner.

[0081] Specifically, in this embodiment, since the bottom of the mounting area 21 is supported by the foot 10, compared to setting the first drainage hole 214 in other locations, the first drainage hole 214 is set in the mounting area 21, and a second drainage hole 15 corresponding to the first drainage hole 214 is opened on the main body 11 of the foot 10, which has a smaller impact on the structural strength of the chassis 20.

[0082] It is important to note that the base plate 10 should be made of materials such as aluminum alloy or stainless steel, which can effectively prevent oxidation and corrosion. This will prevent the condensate drained from the second drain hole 15 of the base plate 10 from corroding the base plate 10, causing it to deform or even be damaged, which could result in the outdoor unit of the air conditioner tilting or falling off.

[0083] In this embodiment, both the first drainage hole 214 and the second drainage hole 15 are round holes. Round holes have less impact on the structural strength of the base plate and the foot 10 compared to other shapes such as square holes.

[0084] In this embodiment, the centers of the first drain hole 214 and the second drain hole 15 are aligned, and the diameter of the second drain hole 15 should be greater than or equal to the diameter of the first drain hole 214. This arrangement allows condensate to drain directly from the first drain hole 214 through the second drain hole 15 without obstruction, preventing condensate from remaining between the base plate and the footplate 10, thereby preventing long-term moisture retention that could cause corrosion and odor.

[0085] In some embodiments, the first drain hole 214 and the second drain hole 15 do not need to be perfectly aligned, and the shapes and sizes of the first drain hole 214 and the second drain hole 15 may also be different.

[0086] In some embodiments, the main body 11 is further provided with a first welding positioning hole 16, and the mounting area 21 is provided with a second welding positioning hole 215 that cooperates with the first welding positioning hole 16.

[0087] Thus, the first welding positioning hole 16 and the second welding positioning hole 215 can be used for welding positioning, so that the foot 10 and the base plate can be connected by welding to further enhance the stability of the connection.

[0088] Specifically, in this embodiment, the foot 10 and the chassis 20 are connected by welding. The first welding positioning hole 16 and the second welding positioning hole 215 provide a precise positioning reference for welding the body 11 of the foot 10 to the mounting area 21 of the chassis 20. During the welding process, by aligning the first welding positioning hole 16 and the second welding positioning hole 215, it can be ensured that the body 11 of the foot 10 is accurately installed in the designated position of the chassis 20, ensuring the relative positional accuracy between the foot 10 and the chassis 20, thereby improving the installation quality of the entire outdoor unit of the air conditioner. Precise positioning helps to improve the welding quality, making the weld between the body 11 of the foot 10 and the mounting area 21 of the chassis 20 more secure. Furthermore, the first welding positioning hole 16 and the second welding positioning hole 215 can increase the contact area of ​​the welded part, improve the welding strength, thereby enhancing the connection stability between the foot 10 and the chassis 20, enabling the outdoor unit of the air conditioner to withstand greater vibration and load during operation, and reducing failures caused by loose connections.

[0089] Furthermore, the arrangement of the first welding positioning hole 16 and the second welding positioning hole 215 facilitates automated welding.
