[0052] In this application, "multiple" means two or more (including two).

[0053] The following is for reference. Figures 1-9 The present application describes a chassis 100 and an air conditioner 1000 according to embodiments thereof.

[0054] like Figure 3 , Figure 4 as well as Figure 9 As shown, according to the first aspect embodiment of this application, the chassis 100 includes: a body 10, a first positioning part 20, and a first mating part 30.

[0055] The body 10 has a first surface 10a and a second surface 10b that are disposed opposite to each other; a first positioning part 20 is formed on the first surface 10a; a first mating part 30 is formed on the second surface 10b, and the first mating part 30 is used to position and engage with the first positioning part 20; multiple chassis 100 are suitable for stacking and storage, and among adjacent chassis 100, the first positioning part 20 of one chassis 100 is suitable for insertion and engagement with the first mating part 30 of another chassis 100, so as to achieve the limiting of adjacent chassis 100 when multiple chassis 100 are stacked and stored.

[0056] Specifically, the chassis 100 includes a body 10, which may have two surfaces arranged opposite each other in the height direction, namely a first surface 10a and a second surface 10b. A first positioning part 20 is provided on the first surface 10a, and a first mating part 30 is provided on the second surface 10b. Thus, the first positioning part 20 and the first mating part 30 are respectively provided on both sides of the body 10 in the height direction. For example, the first positioning part 20 may be provided at the top of the body 10, and the first mating part 30 may be provided at the bottom of the body 10. The first mating part 30 is used to position and engage with the first positioning part 20. When multiple chassis 100 are stacked, the first mating part 30 located at the bottom of one chassis 100 may be inserted and engaged with the first positioning part 20 located at the top of another chassis 100. Through the insertion and engagement of the first mating part 30 and the first positioning part 20, the relative movement between the chassis 100 in the horizontal direction and the relative position between the chassis 100 in the height direction can be restricted. This allows multiple chassis 100 to be stacked in the height direction, while forming a mutually supporting and limiting relationship between the chassis 100, ensuring the stability and safety of adjacent chassis 100 during the stacking process.

[0057] It should be noted that the above-mentioned plug-in connection is a detachable connection form, so that multiple chassis 100 can be disassembled and re-stacked. In this way, when it is necessary to disassemble the chassis 100, the first positioning part 20 and the first mating part 30 can be easily separated along the assembly direction without damaging the chassis 100 itself.

[0058] According to the chassis 100 of this application, the stacking stability of multiple chassis 100 can be improved by the insertion and engagement of the first positioning part 20 and the first mating part 30, realizing the self-positioning of the stacked chassis 100, preventing the chassis 100 from collapsing or sliding and causing damage. It can effectively solve the problems of easy collapse and defective incoming materials of the chassis 100, reduce the material scrap rate, optimize production costs, and create prerequisites for the automated modification of the chassis 100 assembly of subsequent production lines. Through the insertion and engagement of the first positioning part 20 and the first mating part 30, multiple chassis 100 can be automatically aligned and inserted together, thereby facilitating automated assembly and saving labor and time costs.

[0059] like Figure 4 , Figure 6 , Figure 7 as well as Figure 9 As shown, according to some embodiments of this application, the first positioning part 20 is configured as a first positioning post, the first mating part 30 is configured as a second positioning post, and the first positioning post is formed with a countersunk groove 32 for the second positioning post to be inserted, or the second positioning post is formed with a countersunk groove 32 for the first positioning post to be inserted.

[0060] Specifically, the first positioning part 20 can be constructed as a first positioning post protruding from the first surface 10a, and the first mating part 30 can be constructed as a second positioning post protruding from the second surface 10b. At least one of the first positioning post and the second positioning post has a countersunk groove 32. The countersunk groove 32 can be formed in such a way that only the first positioning post has a countersunk groove 32, while the second positioning post does not have a countersunk groove 32, in which case the second positioning post is suitable to be inserted into the countersunk groove 32 of the first positioning post to achieve a plug-in fit. Alternatively, the countersunk groove 32 can be formed in such a way that only the second positioning post has a countersunk groove 32, while the first positioning post does not have a countersunk groove 32, in which case the first positioning post is suitable to be inserted into the countersunk groove 32 of the second positioning post to achieve a plug-in fit. Furthermore, the countersunk groove 32 can be formed in such a way that both the first positioning post and the second positioning post have countersunk grooves 32, and the one with a relatively smaller diameter is suitable to be inserted into the countersunk groove 32 of the other to achieve a plug-in fit.

[0061] By using a countersunk groove 32 to accommodate the first or second positioning post for insertion, on the one hand, the first and second positioning posts have mating surfaces in both the circumferential and axial directions, which increases the connection range and area between the first and second positioning posts, thus enhancing connection stability and providing stronger support for the chassis 100 stacked in the height direction, thereby improving stacking stability and safety. On the other hand, using a countersunk groove 32 to accommodate the first or second positioning post for insertion also improves the self-positioning accuracy and convenience of the stacked chassis 100, which is beneficial for improving assembly accuracy and efficiency.

[0062] like Figure 6 As shown, according to some embodiments of this application, the countersunk groove 32 includes a first groove segment 32a and a second groove segment 32b arranged sequentially in the insertion direction. The inner diameter of the first groove segment 32a is larger than the inner diameter of the second groove segment 32b to define a positioning step portion 32c.

[0063] Specifically, the countersunk groove 32 includes a first groove segment 32a and a second groove segment 32b. The first groove segment 32a is located at the end of the second groove segment 32b away from the body 10. The end of the first groove segment 32a away from the second groove segment 32b in the insertion direction participates in defining the open end of the countersunk groove 32. The inner diameter of the first groove segment 32a is larger than the inner diameter of the second groove segment 32b to define the positioning step portion 32c. When two chassis 100s are stacked, a first positioning post on the first surface 10a of one chassis 100 and a second positioning post on the second surface 10b of the other chassis 100 are engaged through a countersunk groove 32. For ease of explanation, the example is that the second positioning post is inserted into the countersunk groove 32 of the first positioning post. During the engagement of the second positioning post and the countersunk groove 32 of the first positioning post, the free end of the second positioning post (i.e., the end of the second positioning post away from the body 10 of the chassis 100) will abut against the positioning step 32c in the countersunk groove 32 of the first positioning post, thereby limiting the second positioning post and the first positioning post in the height direction (i.e., the opposite direction of the first surface 10a and the second surface 10b). This ensures that the self-positioning of the stacked chassis 100s is accurately limited in the height direction, thus ensuring good stacking stability between the chassis 100s.

[0064] It should be noted that the height of the positioning step 32c inside the countersunk groove 32 can be adjusted according to the stacking requirements of the chassis 100 of different models and specifications of air conditioners, thereby enhancing the adaptability and versatility of the first and second positioning posts. Furthermore, by adjusting the relative lengths of the first groove segment 32a and the second groove segment 32b in the insertion direction to adjust the height of the positioning step 32c inside the countersunk groove 32, the chassis 100 can be adapted to the stacking requirements of different models and specifications. Whether stacked with chassis 100 of the same model or with chassis 100 of different models, a stable and accurate stacking effect can be achieved, thus enhancing the versatility and applicability of the chassis 100.

[0065] like Figure 9 As shown, according to some embodiments of this application, the ends of the first positioning post and / or the second positioning post facing each other are provided with a first guide portion 34 whose cross-sectional area gradually increases in the direction away from each other.

[0066] Specifically, at least one of the first positioning post and the second positioning post is provided with a first guide portion 34. The first guide portion 34 can be configured such that only the first positioning post is provided with the first guide portion 34, while the second positioning post is not provided with the first guide portion 34. The first guide portion 34 is located at the end of the first positioning post facing the second positioning post, and its cross-sectional area gradually increases in the direction away from the second positioning post. Alternatively, the first guide portion 34 can be configured such that only the second positioning post is provided with the first guide portion 34, while the first positioning post is not provided with the first guide portion 34. The first guide portion 34 is located at the end of the second positioning post facing the first positioning post, and its cross-sectional area gradually increases in the direction away from the first positioning post. Another possible configuration is such that both the first and second positioning posts are provided with the first guide portion 34, and the cross-sectional areas of the first guide portion 34 on the first positioning post and the first guide portion 34 on the second positioning post gradually increase in the direction away from each other. The first guide part 34 can play a good guiding and positioning role, which helps to make the first positioning post of one chassis 100 and the second positioning post of another chassis 100 more easily and smoothly aligned and engaged during the stacking and assembly process of chassis 100, thereby improving stacking efficiency and accuracy, and further creating more favorable conditions for the automated assembly of chassis 100.

[0067] like Figure 3 , Figure 4 as well as Figure 7As shown, according to some embodiments of this application, a mounting boss 40 is formed on the first surface 10a, the mounting boss 40 is used to mount the housing 200, and a mounting part 50 is formed on the mounting boss 40. A support column 60 is provided on the second surface 10b, the support column 60 is located on the side of the mounting part 50 away from the first surface 10a, and in adjacent chassis 100, the support column 60 of one chassis 100 is adapted to be inserted and cooperate with the mounting part 50 of another chassis 100, so as to realize the limiting between adjacent chassis 100 when multiple chassis 100 are stacked and stored.

[0068] Specifically, a mounting boss 40 is provided on the first surface 10a. The mounting boss 40 is used to install the housing 200 portion of the air conditioner 1000. A mounting part 50 can be formed on the mounting boss 40. The mounting part 50 can be used to assemble important support components with pin features, such as the housing 200. On the side of the mounting part 50 away from the first surface 10a, a support column 60 corresponding to the mounting part 50 is provided. It can be understood that the support column 60 and the mounting part 50 are respectively provided on both sides of the body 10 in the height direction, and the projections of the support column 60 and the mounting part 50 in the height direction correspond. For example, the support column 60 can be provided at the bottom end of the body 10, and the mounting part 50 can be provided at the top end of the body 10. The support column 60 can be used to support the overall weight of the air conditioner 1000. When multiple chassis 100 are stacked, the support column 60 at the bottom of one chassis 100 can interlock with the mounting part 50 at the top of another chassis 100. This can be understood as the upper chassis 100 inserting its support column 60 into the mounting part 50 of the lower chassis 100. This interlocking of the support column 60 and mounting part 50 restricts relative movement between the chassis 100 in the horizontal direction and enhances the stacking constraint effect in the vertical direction. Thus, while enabling multiple chassis 100 to be stacked vertically, a mutually supporting and constraining relationship is formed between the chassis 100, ensuring the stability and constraint effect of adjacent chassis 100 during the stacking process.

[0069] It should be noted that the mounting part 50 and the support column 60 can be configured as multiple one-to-one correspondences, and are distributed at intervals around the mounting boss 40 or at specific positions to enhance the connection and limiting strength between the chassis 100; similarly, the plug-in engagement between the mounting part 50 and the support column 60 is a detachable connection form, so that multiple chassis 100 can be disassembled and re-stacked. When it is necessary to disassemble the chassis 100, the support column 60 can be easily pulled out from the mounting part 50 along the assembly direction without damaging the chassis 100 itself.

[0070] Furthermore, in some specific embodiments of this application, such as Figure 4As shown, the mounting parts 50 and support columns 60 are configured in a one-to-one correspondence, and at least a portion of the mounting parts 50 and corresponding support columns 60 are spaced apart around the mounting boss 40. The body 10 has a plurality of fixing screw holes 13 arranged circumferentially. The plurality of fixing screw holes 13 are adapted to cooperate with fasteners to connect the chassis 100 to some other components of the air conditioner 1000. Among them, a mounting part 50 and a corresponding support column 60 are arranged between two adjacent fixing screw holes 13. The arrangement of a mounting part 50 and a corresponding support column 60 between two adjacent fixing screw holes 13 is beneficial to enhancing the structural stability and stress uniformity of the chassis 100, improving the durability and stacking stability of the chassis 100.

[0071] like Figure 3 As shown, according to some embodiments of this application, the mounting boss 40 is disposed around the body 10, and the first positioning part 20 is disposed on the middle area of ​​the body 10.

[0072] Specifically, the mounting boss 40 surrounds the body 10, the first positioning part 20 is disposed on the middle area of ​​the body 10, and the first mating part 30 is disposed on the middle area of ​​the body 10 at a position corresponding to the first positioning part 20. Thus, when the chassis 100 are stacked, the middle area between the chassis 100 can form a good connection and limit through the first positioning part 20 and the first mating part 30. The first positioning part 20 and the first mating part 30 can provide good support for the chassis 100 in the middle area between adjacent chassis 100, which can prevent the stacked chassis 100 from tilting and collapsing, effectively improve the stability of the chassis 100 stacking, so as to enable self-positioning and realize automated assembly.

[0073] like Figures 4-9 As shown, according to some embodiments of this application, the mounting portion 50 is formed as a mounting countersunk hole, and the projected profile of the mounting countersunk hole in the stacking direction is larger than the projected profile of the support column 60 in the stacking direction, so that the support column 60 and the mounting countersunk hole are in clearance fit.

[0074] Specifically, the mounting part 50 can be formed as a recessed mounting countersunk hole facing the second surface 10b of the main body 10. When multiple chassis 100 are stacked, the support column 60 at the bottom of one chassis 100 can be inserted into the corresponding mounting countersunk hole at the top of another chassis 100 and abut against the bottom wall of the mounting countersunk hole, thus forming a stable connection between the chassis 100. At the same time, the insertion and engagement of the support column 60 with the mounting countersunk hole also restricts the relative movement of the chassis 100 in the horizontal direction, thereby preventing shaking or tipping during stacking. The projected profile of the mounting countersunk hole in the stacking direction is larger than the projected profile of the support column 60 in the stacking direction. The outer peripheral surface of the support column 60 is spaced a certain distance from the inner peripheral wall of the mounting countersunk hole, so that the support column 60 and the mounting countersunk hole can be in a clearance fit state during stacking and assembly, so as to pre-position the chassis 100. This can improve the accuracy and efficiency of chassis 100 stacking and assembly.

[0075] Furthermore, the clearance fit between the support column 60 and the mounting countersunk hole allows the support column 60 to be easily inserted into the mounting countersunk hole, and the positioning column can be easily pulled out when the stacked chassis 100 needs to be disassembled, thus effectively improving the convenience and efficiency of assembly and disassembly operations between chassis 100. Moreover, due to the existence of the clearance, even if a certain impact or vibration occurs during stacking, it can effectively reduce wear and damage between components. Therefore, the clearance fit between the support column 60 and the mounting countersunk hole also provides good protection for the chassis 100.

[0076] like Figure 5 As shown, according to some embodiments of this application, a second guide portion 51 is provided on the open side edge of the mounting hole.

[0077] Specifically, the mounting countersunk hole is recessed towards the second surface 10b, and has a certain depth in the direction opposite to the first surface 10a and the second surface 10b. The end of the mounting countersunk hole near the second surface 10b forms a bottom wall, and the end away from the second surface 10b is an open side, suitable for the insertion of the support column 60. A second guide portion 51 is provided on the open side edge of the mounting countersunk hole. By providing the second guide portion 51, on the one hand, the second guide portion 51 can play a good guiding and positioning role, so that during the stacking of multiple chassis 100, the support column 60 of the previous chassis 100 can easily and quickly enter the mounting countersunk hole of the next chassis 100 to achieve pre-positioning, thereby improving stacking efficiency and accuracy, and ensuring that the chassis 100 maintain the correct positional relationship during the stacking process. This can avoid the occurrence of chassis 100 misalignment or tilting and other problems that could cause damage to the chassis 100, improve the stacking stability of the chassis 100, and improve the overall quality and reliability of the product.

[0078] Furthermore, in some specific embodiments of this application, the second guide portion 51 is configured such that its projected area gradually decreases in the direction from the first surface 10a to the second surface 10b, and the second guide portion 51 is defined as an inclined surface to ensure good guidance and positioning.

[0079] like Figure 7 As shown, according to some embodiments of this application, the body 10 also includes a skirt portion 11 surrounding the mounting boss 40. The skirt portion 11 and the support column 60 define a support surface 10c located below the second surface 10b, and the support column 60 and the first mating part 30 are both located inside the skirt portion 11.

[0080] Specifically, the skirt portion 11 surrounds the mounting boss 40. The side surface of the skirt portion 11 facing away from the first surface 10a in the direction opposite to the second surface 10b and the side surface of the support column 60 facing away from the second surface define a support surface 10c, and the support surface 10c is located below the second surface 10b. The addition of the skirt portion 11 increases the area of ​​the support surface 10c, providing a wider and more stable support base for the chassis 100, which helps to further improve the stability of the chassis 100 during stacking and placement, and enhances the support of the chassis 100 for the housing 200, etc. The support column 60 and the first mating part 30 are both located inside the skirt part 11 to protect the mating between the support column 60 and the mounting part 50 and the mating between the first mating part 30 and the first positioning part 20 from interfering with the skirt part 11. At the same time, under the protection of the skirt part 11, the support column 60 and the first mating part 30 will not interfere with other components, thereby preventing damage caused by mutual interference during stacking and effectively protecting the integrity of the support column 60 and the first mating part 30.

[0081] Furthermore, in some specific embodiments of this application, such as Figure 8 and Figure 9 As shown, the body 10 also includes a plurality of first reinforcing ribs 12 spaced apart around the support column 60, and at least a portion of the first reinforcing ribs 12 is separated from the support column 60; a plurality of second reinforcing ribs 14 are provided around the first mating part 30. The second reinforcing ribs 14 can enhance the structural strength of the first mating part 30 and improve its durability. The first reinforcing ribs 12 can effectively strengthen and reinforce the support column 60, improving its durability and reliability. The fact that at least a portion of the first reinforcing ribs 12 is spaced apart from the support column 60 allows for sufficient space to be reserved for the mating of the support column 60 and the mounting part 50, protecting the support column 60 and the mounting part 50 from interference with the first reinforcing ribs 12.

[0082] Furthermore, in some other specific embodiments of this application, such as Figure 8As shown, the first reinforcing rib 12 includes a first segment 12a and a second segment 12b. One end of the first segment 12a is connected to the support column 60, and the other end is connected to the second segment 12b. The first segment 12a and the second segment 12b are connected to the mounting boss 40 on the same side in the direction opposite to the first surface 10a and the second surface 10b. In the direction from the first surface 10a to the second surface 10b, the length of the first segment 12a is less than the length of the second segment 12b, thus defining a clearance space between it and the support column 60, so as to play a good clearance and protection role for the support column 60.

[0083] Furthermore, in some embodiments, the contour of the side of the first segment 12a facing away from the first surface 10a is constructed as an arc. The surface of the side of the first segment 12a facing away from the first surface 10a is the surface close to the mating surface between the support column 60 and the mounting part 50. By constructing the contour of the side of the first segment 12a facing away from the first surface 10a as an arc, the surface of the first segment 12a facing away from the first surface 10a is smooth, which can further enhance the protection of the support column 60 and the mounting part 50, etc.

[0084] like Figure 8 As shown, according to some embodiments of this application, the cross-sectional area of ​​the support column 60 gradually decreases in the direction away from the second surface 10b.

[0085] Specifically, the cross-sectional area of ​​the support column 60 gradually decreases in the direction away from the second surface 10b, that is, the cross-sectional area of ​​the support column 60 gradually decreases in the direction from the first surface 10a to the second surface 10b. In this way, on the one hand, it can play a good guiding role in the process of inserting the support column 60 into the mounting part 50, which can improve the accuracy and efficiency of the insertion fit; on the other hand, by adopting the form of gradually decreasing cross-sectional area of ​​the support column 60, the support column 60 can gradually adapt to the shape and size of the mounting part 50 during the insertion process, thereby improving the fit stability between the support column 60 and the mounting hole.

[0086] Furthermore, in some specific embodiments of this application, the support column 60 is constructed as a frustum shape with a gradually decreasing cross-sectional area in the direction away from the mounting portion 50, and the projected outline of the mounting portion 50 in the height direction is constructed as a square. The side of the support column 60 away from the second surface 10b is formed as a flat surface to ensure a stable fit between the support column 60 of one chassis 100 and the mounting portion 50 of the other chassis 100.

[0087] like Figure 1-Figure 3 As shown, according to some embodiments of this application, the housing 200 includes a rear box 201 and a panel 202. The mounting boss 40 includes a first boss 41 for mounting the rear box 201 and a second boss 42 for mounting the panel 202. The first boss 41 is higher than the second boss 42, and mounting portions 50 are formed on both the first boss 41 and the second boss 42.

[0088] Specifically, the panel 202 and the rear box 201 can be arranged opposite each other, and the panel 202 and the rear box 201 can serve to decorate, beautify, and protect the internal components of the air conditioner 1000. The mounting boss 40 is divided into a first boss 41 for mounting the rear box 201 and a second boss 42 for mounting the panel 202. The height of the first boss 41 is higher than that of the second boss 42 to accommodate the different height requirements of the rear box 201 and the panel 202, so as to ensure that the rear box 201 and the panel 202 can be stably and accurately installed on the chassis 100. Furthermore, mounting portions 50 are formed on both the first protrusion 41 and the second protrusion 42. During the stacking of multiple chassis 100, the support column 60 on the second surface 10b of the area corresponding to the first protrusion 41 of the previous chassis 100 cooperates with the mounting portion 50 on the first protrusion 41 of the next chassis 100, and the support column 60 on the second surface 10b of the area corresponding to the second protrusion 42 of the previous chassis 100 cooperates with the mounting portion 50 on the second protrusion 42 of the next chassis 100. Thus, the mounting portions 50 and support columns 60 on the second protrusion 42 and the first protrusion 41 form a good insertion fit, which can ensure the limiting coverage range of the stacking of two chassis 100 and effectively ensure good stacking stability between chassis 100.

[0089] Furthermore, in some specific embodiments of this application, such as Figure 3 As shown, a first mounting portion 50a is provided on the first boss 41, and a first support column corresponding to the first mounting portion 50a is provided on the second surface 10b. Multiple first mounting portions 50a and first support columns are constructed, with the multiple first mounting portions 50a evenly and spaced apart around the first boss 41, and the multiple first support columns corresponding one-to-one with the multiple first mounting portions 50a. A second mounting portion 50b is provided on the second boss 42, and a second support column corresponding to the second mounting portion 50b is provided on the second surface 10b. Multiple second mounting portions 50b and second support columns are constructed, with the multiple second mounting portions 50b evenly and spaced apart around the second boss 42, and the multiple second support columns corresponding one-to-one with the multiple second mounting portions 50b. This ensures the stacking stability of the chassis 100.

[0090] Furthermore, in some other specific embodiments of this application, the number of first mounting portions 50a on the first boss 41 is configured to be four to six, and the number of first support columns corresponds to the number of first mounting portions 50a to be four to six. The number of second mounting portions 50b on the second boss 42 is configured to be four to six, and the number of second support columns corresponds to the number of second mounting portions 50b to be four to six, so as to ensure that the chassis 100 has good stacking stability.

[0091] like Figure 1 and Figure 2As shown, according to the second aspect embodiment of the present application, the air conditioner 1000 includes: a housing 200 and a chassis 100 as described in any of the above embodiments. The bottom end of the housing 200 is connected to the chassis 100, so that the housing 200 and the chassis 100 can jointly define a receiving cavity for housing the internal components of the air conditioner 1000. The housing 200 and the chassis 100 can provide support, fixation and protection for the internal components of the air conditioner 1000.

[0092] In addition, in some specific embodiments of this utility model, the air conditioner 1000 also includes an air outlet frame assembly 300, a fan wheel 301, an air duct volute assembly 302, an evaporator assembly 303, a sealing plate 304, an evaporator 305, an electric auxiliary heater 306, a motor 307, an electrical control box assembly 308, and a top cover 400.

The air outlet frame assembly 300 is responsible for evenly blowing the treated air into the room to achieve the air outlet function of the air conditioner 1000. The impeller 301, driven by the motor 307, generates airflow to draw air into the air conditioner 1000. After being processed by components such as the evaporator assembly 303, evaporator 305, and electric auxiliary heater 306, the air is then delivered out by the air outlet frame assembly 300, thus achieving the air outlet function of the air conditioner 1000. The air conditioner 1000 has functions such as air outlet; the air duct volute assembly 302 can guide airflow to ensure the correct airflow direction; the sealing plate 304 can improve the sealing of the internal structure of the air conditioner 1000 to improve the working efficiency of the air conditioner 1000; the electrical control box assembly 308 is used to control the power distribution and logic operation of the entire air conditioner 1000 system to ensure the normal functioning of the air conditioner 1000; the top cover 400 is set at the top of the housing 200, opposite to the chassis 100, and the top cover 400 closes the receiving cavity. The top cover 400 can fix and protect the internal components of the air conditioner 1000 and can increase the aesthetics of the exterior of the air conditioner 1000.
