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.

[0020] 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.

It should also be understood that additional or alternative steps may be used.

[0021] 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.

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.

[0022] 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.

Therefore, the example term "below" can include both upper and lower orientations.

[0023] like Figures 1 to 6As shown, according to an embodiment of this utility model, a top cover reinforcement structure is proposed, including a cover body 1 and a first reinforcement part 2. The cover body 1 includes a main body 11 and two first side wall parts 12. The two first side wall parts 12 are respectively connected to opposite ends of the main body 11 along the first direction X and extend towards the lower side of the main body 11. The first direction X is perpendicular to the vertical direction Y. The main body 11 is usually a flat or near-flat frame structure, mainly used to cover the top space of a cabinet air conditioner and directly bear external impacts, vibrations, or the weight transmission of internal equipment. The left and right sides of the edge of the main body 11 extend downward to form vertical / inclined wall structures, and the two are arranged opposite each other, that is, symmetrically distributed from left to right. The main body 11 and the two first side wall parts 12 are usually integrally formed, such as by stamping metal sheets or injection molding. The first reinforcement part 2 is connected to the inner side of the main body 11, that is, the side surface close to the interior of the unit, so that it fits tightly with the main body 11 and forms direct support for the main body 11 under stress.

[0024] The first reinforcing part 2 is connected to the main body 11 and extends along the first direction X. The first reinforcing part 2 is connected to two first sidewall parts 12 at opposite ends along the first direction X. In this embodiment, the first reinforcing part 2 and the cover 1 are integrally molded using injection molding. Through this connection, the first reinforcing part 2 and the first sidewall parts 12 on both sides form a stable structure. That is, the main body 11 serves as the intermediate bearing surface, the first sidewall parts 12 on both sides serve as vertical supports, and the first reinforcing part 2 serves as a pressure transmission component. The three work together to resist bending, torsional, or impact loads that the top cover may be subjected to. The first reinforcing part 2 can also be connected to the cover 1 by welding, bolting, or snap-fitting.

[0025] The top cover reinforcement structure of this utility model adopts an integrated structure to replace the traditional separate foam and sheet metal reinforcement plates. This not only eliminates the use of two separate materials but also simplifies the manual assembly process. While ensuring the strength of the top cover structure, it reduces material costs and assembly complexity. At the same time, the integrated top cover structure is more compatible with automated equipment for grasping and positioning, creating feasible conditions for the implementation of automated assembly in the top cover final assembly stage and reducing the difficulty of automation in the final assembly stage.

[0026] In some embodiments of this utility model, the first reinforcing part 2 includes a first crossbeam 21, a second crossbeam 22 and a connecting plate 23. The first crossbeam 21 and the second crossbeam 22 extend along the first direction X and are spaced apart along the vertical direction Y. The connecting plate 23 is connected to the first crossbeam 21 and the second crossbeam 22.

[0027] like Figure 1 and Figure 2As shown, both the first crossbeam 21 and the second crossbeam 22 are long strip beams extending along the first direction X. The opposite ends of the first crossbeam 21 are connected to the two first sidewall portions 12, and the opposite ends of the second crossbeam 22 are also connected to the two first sidewall portions 12. The two crossbeams are arranged in layers in a direction perpendicular to the plane of the main body 11. The second crossbeam 22 is positioned closer to the main body 11 than the first crossbeam 21. The first and second crossbeams 21 and 22 provide lateral support and load-bearing capacity. A connecting plate 23, perpendicular to the first and second crossbeams 21 and 22, connects one side of the two crossbeams along the vertical direction Y, forming a single integrated structure. When the structure is subjected to external forces, the connecting plate 23 effectively transmits and disperses the force between the first and second crossbeams 21 and 22, preventing relative displacement or deformation of the two crossbeams in the vertical direction Y, thereby enhancing the stability of the entire first reinforcing part 2 in both directions.

[0028] In other embodiments, the number of crossbeams in the first reinforcing part 2 can be adjusted to one, three, four or more, depending on the actual structural strength requirements and load distribution requirements of the roof. At the same time, the extension direction of the crossbeams can also be adjusted to other directions according to the main stress characteristics of the roof. Under the premise of ensuring structural strength, stability and load transfer efficiency, a balance between performance optimization and cost control can be achieved to meet the needs of diverse engineering scenarios.

[0029] In some embodiments of this utility model, the first reinforcing part 2 further includes a plurality of anti-shrinkage ribs 24, which are spaced apart along the first direction X. Each anti-shrinkage rib 24 is connected to the first crossbeam 21 and the second crossbeam 22 respectively. Along the vertical direction Y, the end of the anti-shrinkage rib 24 away from the first crossbeam 21 is connected to the main body part 11.

[0030] like Figure 2 As shown, multiple anti-shrinkage ribs 24 are arranged at intervals along the first direction X, and the two ends of the anti-shrinkage ribs 24 along the vertical direction Y are respectively connected to the first crossbeam 21 and the main body 11. The multiple anti-shrinkage ribs 24 divide the space between the first crossbeam 21 and the second crossbeam 22 into multiple independent first anti-shrinkage grooves 25. The first anti-shrinkage grooves 25 have openings on the side away from the connecting plate 23. The multiple anti-shrinkage ribs 24 can suppress the shrinkage deformation of the first crossbeam 21 and the second crossbeam 22 under stress or temperature changes, thereby enhancing the structural stability. The first anti-shrinkage grooves 25 can provide a certain deformation buffer space for the structure under thermal expansion and contraction, reducing the risk of cracking caused by internal stress concentration. The connecting plate 23 connects the first crossbeam 21 and the second crossbeam 22 on the side, making them form a more stable whole to jointly bear external forces. At the same time, the connection between the anti-shrinkage ribs 24 and the main body 11 also allows the first reinforcing part 2 to work in coordination with the main body 11, improving the load-bearing capacity and overall performance of the entire structure.

[0031] like Figure 2 As shown, in some embodiments of this utility model, the thickness of the anti-shrinkage rib 24 gradually decreases in the first direction X from the first crossbeam 21 toward the main body 11. When performing molding processes such as injection molding, the anti-shrinkage rib 24 near the first crossbeam 21 has a relatively large thickness, which can provide more stable support for the flow, pressure holding and cooling of the melt, so that the melt is less likely to produce shrinkage marks due to stress concentration or poor flow when it cools and shrinks in this area; as it extends toward the main body 11, the thickness of the anti-shrinkage rib 24 gradually decreases, so that the excessively thick anti-shrinkage rib 24 in some areas will not generate excessive shrinkage tension during cooling, thus avoiding the pulling deformation of the adjacent main body 11 surface, so that the surface will not have shrinkage such as dents or wrinkles.

[0032] like Figure 2 As shown, in some embodiments of this utility model, the width of the anti-shrinkage rib 24 gradually increases from the first crossbeam 21 towards the main body 11. The anti-shrinkage rib 24 gradually increases in width from the first crossbeam 21 towards the main body 11, meaning its cross-section is a trapezoidal shape, narrower at the top and wider at the bottom. This allows the narrow top near the first crossbeam 21 to form a small-area connection with the first crossbeam 21, controlling the shrinkage in this area to avoid stress concentration and deformation of the crossbeam surface. The wide bottom end makes large-area contact with the large volume of material in the main body 11, evenly distributing the stress generated by the anti-shrinkage rib 24 and the main body 11 during cooling and shrinkage, preventing localized stretching of the surface. Furthermore, the wide bottom increases the contact area with the main body 11, allowing for more thorough heat exchange between the anti-shrinkage rib 24 and the large volume of material in the main body 11 during cooling. This ensures the cooling speed matches the overall rhythm of the main body 11, compensating for minor deformations caused by cooling and shrinkage in the main body 11, thus ensuring a smooth and flat surface and improving the reliability and appearance quality of the top cover reinforcement structure.

[0033] In other embodiments, the cross-sectional shape of the anti-shrinkage rib 24 can also be adjusted to a circle, triangle, ellipse or polygon, etc. Different cross-sectional shapes can not only adapt to diverse structural reinforcement needs, but also control material costs while ensuring anti-shrinkage effect.

[0034] like Figure 1As shown, in some embodiments of this utility model, there are two first reinforcing parts 2, which are symmetrically arranged about the center line of the main body 11 along its length. The two first reinforcing parts 2 have identical structures, located on the left and right sides of the main body 11 along its length, and are symmetrically distributed about the center line of the main body 11, with a certain interval between them. The symmetrical spacing of the two first reinforcing parts 2 along the length of the main body 11 allows the first reinforcing parts 2 on both sides to be simultaneously stressed and work together when the top cover is subjected to external loads, evenly distributing the load to the main body 11 and avoiding deformation or damage caused by localized stress concentration. Simultaneously, by setting the symmetrically distributed double-reinforcing structure, the overall bending and torsional stiffness and stability of the main body 11 in the length direction can be improved.

[0035] In other embodiments, the number of the first reinforcing part 2 can be flexibly adjusted according to the actual structural size of the top cover, load-bearing requirements and stress distribution characteristics. For example, one can be set in the key area of ​​the main body 11, or three, four or more can be evenly set along the length of the main body 11. By increasing or decreasing the number and optimizing the arrangement, the manufacturing cost and weight can be reduced while ensuring structural strength and stability.

[0036] In some embodiments of the present invention, the top cover reinforcing structure further includes a second reinforcing part, which includes a plurality of reinforcing units with the same structure and arranged in an array, and the plurality of reinforcing units are connected to the side of the main body 11 facing the first sidewall 12.

[0037] like Figure 4 As shown, the second reinforcing part includes a first reinforcing unit 31, a second reinforcing unit 32, and a third reinforcing unit 33. The first reinforcing unit 31 is disposed in the middle region between the two first reinforcing parts 2. The first reinforcing unit 31 can further distribute the load transmitted by the first reinforcing parts 2 on both sides to the central region of the main body 11 evenly, while enhancing the local deformation resistance of the middle part, making the stiffness of the top cover in the length direction more uniform and stable when subjected to external loads. The second reinforcing unit 32 and the third reinforcing unit 33 are symmetrically distributed on both sides of the two first reinforcing parts 2. For example, the second reinforcing unit 32 is located on the outer side of the left first reinforcing part 2, and the second reinforcing unit 32 is spaced apart from the left first reinforcing part 2. The third reinforcing unit 33 is located on the outer side of the right first reinforcing part 2, and the third reinforcing unit 33 is spaced apart from the right first reinforcing part 2. The second reinforcing unit 32 and the third reinforcing unit 33 can support and reinforce the edge region of the main body 11, improving the stiffness uniformity and overall stability of the top cover edge region.

[0038] Each reinforcing unit includes multiple first reinforcing ribs 311 with the same structure and arranged periodically. The first reinforcing ribs 311 are regular hexagons. Regular hexagonal structures are subjected to uniform stress and have high structural stability, which can form a stable mechanical load-bearing unit. Multiple such units are spliced ​​together in a periodic pattern, which not only ensures the local reinforcement effect, but also realizes the lightweight and continuity of the overall structure.

[0039] In some embodiments of this utility model, the cover 1 further includes two second sidewall portions 13, which are respectively connected to opposite ends of the main body 11 along a direction perpendicular to the first direction X. The second sidewall portions 13 are connected to the first sidewall portions 12, and a third reinforcing portion is provided on the second sidewall portions 13. The two second sidewall portions 13 are respectively provided on both sides of the length direction of the main body 11. The second sidewall portions 13 and the first sidewall portions 12 together form a multi-directional vertically extending frame structure around the outer periphery of the main body 11, which transmits the top load and external impact force of the main body 11 to the edge of the main body 11 through the first sidewall portions 12 and the second sidewall portions 13 and further disperses them into the overall structure. The third reinforcing portion can strengthen the local stiffness of the second sidewall portions 13, improve the overall bending, torsional and deformation resistance of the cover in three-dimensional space (height, length and width directions), and make the structure more stable and reliable.

[0040] In some embodiments of this utility model, the second sidewall portion 13 extends toward the center of the cover 1 and is provided with a side edge portion 14, and the third reinforcing portion includes a plurality of second anti-shrinkage grooves 41, which are spaced apart along the first direction X on the side edge portion 14 away from the main body portion 11.

[0041] like Figure 3 and Figure 6 As shown, the side edge 14 is an extension of the second side wall 13 protruding towards the main body 11. It is located on the side of the second side wall 13 closest to the main body 11, i.e., the inner area of ​​the top cover side. By providing the side edge 14, the contact area and connection anchor points between the second side wall 13 and the main body 11 are increased, making the connection between the two tighter and stronger. Along the first direction X, a plurality of second anti-shrinkage grooves 41 are provided on the side of the side edge 14 away from the main body 11. The cross-section of the second anti-shrinkage groove 41 is trapezoidal, that is, from the side of the side edge 14 away from the main body 11 to the side of the side edge 14 closer to the main body 11, the width of the second anti-shrinkage groove 41 gradually decreases, forming an overall trapezoidal structure that is wider at the top and narrower at the bottom. This effectively suppresses shrinkage in the non-appearance area on the outer side of the top cover side while improving the deformation resistance and stress coordination performance of this area.

[0042] In some embodiments of the present invention, the third reinforcing part further includes at least one second reinforcing rib 42, and the at least one second reinforcing rib 42 is connected to the side edge part 14 and the second side wall part 13 respectively.

[0043] like Figure 3 and Figure 5 As shown, in this embodiment, there are multiple second reinforcing ribs 42, which are spaced apart along the first direction X on the side edge 14 away from the second anti-shrinkage groove 41, and are located at the connection between the side edge 14 and the second side wall 13. The cross-section of the second reinforcing rib 42 is triangular, with the first side of the triangle connected to the side edge 14 and the second side wall 13 connected to the second side wall 13. The second reinforcing rib 42 is connected to the side edge 14 and the second side wall 13 through an integral injection molding process. When the top cover is subjected to lateral impact or vertical pressure, the second reinforcing rib 42 evenly transmits the stress to the side edge 14 and the second side wall 13, respectively, to avoid stress concentration at the connection point, which could lead to deformation or separation. The integral molding process ensures a seamless connection between the second reinforcing rib 42 and the second side wall 13 and the side edge 14, improving the overall structural integrity and load transfer efficiency, while achieving maximum strength improvement with minimal material usage, thus ensuring the overall strength and stability of the top cover.

[0044] like Figure 5 As shown, in some embodiments of this utility model, a slope 141 is provided on the side of the side edge 14 away from the anti-shrinkage groove. The slope 141 extends downward at an angle from away from the second side wall 13 to close to the second side wall 13. By providing a slope 141 extending downward at an angle close to the second side wall 13 on the side of the side edge 14 away from the anti-shrinkage groove, the mold core can smoothly slide along the slope 141 and gradually detach from the inner surface of the side edge 14 when the top cover is demolded after injection molding or die casting. This avoids excessive frictional resistance or jamming caused by demolding on a vertical surface, thereby reducing the external force required for demolding and preventing the top cover from deforming or being damaged due to demolding stress concentration. At the same time, the inclination direction of the slope 141 is consistent with the conventional demolding movement direction, so efficient demolding can be achieved without adding a complex demolding mechanism, thus improving production efficiency.

[0045] The second aspect of this utility model provides an air conditioner, including a body and the aforementioned top cover reinforcement structure, wherein the top cover reinforcement structure is disposed on the top of the body. When the top cover reinforcement structure is installed on the top of the body, it can provide stable top support for the entire air conditioner, effectively resisting structural deformation caused by installation stress, transportation vibration, top load, and changes in ambient temperature. At the same time, it ensures the smoothness of the top cover surface and the smooth and efficient demolding process, thereby improving the overall structural reliability, durability, and manufacturing quality of the air conditioner.

[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
