In the process of leaving the factory, selling, and installing the air conditioner, it needs to go through multiple logistics transfers; each logistics transfer process will increase the risk of damage to the air conditioner. Among them, the shell of the air conditioner's external unit includes a casing and a top cover plate. The casing includes a front panel, a left side panel, a rear panel, and a right side panel that are connected in sequence. The top cover plate is connected and covered on the top of the casing.

[0003] The top cover plate provided by the related technology usually adopts a large-area flat sheet metal structure, and reinforcing ribs are also provided on the top cover plate to improve the structural strength of the top cover plate; however, the top cover plate provided by the related technology still has the problem of insufficient rigidity, and it is difficult to cope with illegal external forces during loading and unloading, transportation, installation, maintenance, and use.

[0081] Two first reinforcing ribs 110 are arranged at intervals in the length extension direction of the cover plate body 100, and the first rib portion 111 of the first reinforcing rib 110 is extended along the width extension direction of the cover plate body 100, and the second rib portion 112 of the first reinforcing rib 110 is extended along the length extension direction of the cover plate body 100. The first reinforcing ribs 110 can be used to improve the strength and rigidity of the top cover plate 010, so as to improve the problem that the top cover plate 010 is easily deformed under the action of illegal external forces such as stepping, thereby ensuring the reliability of the appearance and structural strength of the top cover plate 010.

[0082] Furthermore, the two first reinforcing ribs 110 are symmetrically distributed; the second rib 112 is connected to the middle of the length extension direction of the first rib 111, that is, along the width extension direction of the cover body 100, the second rib 112 is connected to the middle of the first rib 111.

[0090] Of course, in other embodiments, the end of the first rib 111 away from the second rib 112 may also be spaced apart from the end of the cover body 100 , which is not specifically limited here.

[0091] Please refer to Figure 1 and Figure 2 , the size of the first reinforcing rib 110 can be set as needed; wherein, the width of the cover body 100 is D, and the length of the cover body 100 is L; along the width extension direction of the cover body 100, the length of the first rib 111 is D1, and the length of the first rib 111 satisfies: 3 / 4D<D1<D; along the width extension direction of the cover body 100, the width of the second rib 112 is D2, and the width of the second rib 112 satisfies: 1 / 5D≤D2≤1 / 3D; along In the length extension direction of the cover body 100, the sum of the width of the first rib 111 and the length of the second rib 112 is L1, and the sum of the width of the first rib 111 and the length of the second rib 112 satisfies: 1 / 3L<L1<1 / 2L; along the length extension direction of the cover body 100, the width of the first rib 111 is L2, specifically, the length of the fourth side 116 is L2, and the width L2 of the first rib 111 satisfies: 1 / 5L1≤L2≤1 / 3L1.

This can effectively improve the strength and rigidity of the top cover 010, so as to reliably improve the problem that the top cover 010 is easily dented, deformed, or damaged due to illegal external forces such as trampling.

[0092] Optionally, along the width extension direction of the cover body 100, both ends of the first rib 111 are spaced apart from the long side 101 of the cover body 100, that is, the two fourth side edges 116 are respectively spaced apart from the corresponding long sides 101 of the cover body 100; in this way, the first rib 111 can be utilized to reliably improve the strength and rigidity of the top cover 010.

[0093] In this embodiment, each vertex of the first rib 111 and the second rib 112 is set to a rounded transition, and the connection between the first rib 111 and the second rib 112 is an arc transition; specifically, the connection between the third side 115 and the fourth side 116, the connection between the fourth side 116 and the first side 113, and the connection between the second side 114 and the fifth side 117 are all set to a rounded transition, and the connection between the first side 113 and the second side 114 is an arc transition. By setting the rounded (arc) transition, stress concentration can be effectively reduced, thereby improving the problem that the top cover plate 010 is easily dented, deformed, and damaged due to external forces such as stepping.

[0094] Of course, in other embodiments, only the vertices of one of the first rib 111 and the second rib 112 may be set as a rounded transition, for example: only the connection between the third side 115 and the fourth side 116, and the connection between the fourth side 116 and the first side 113 are set as a rounded transition, or, only the connection between the second side 114 and the fifth side 117 is set as a rounded transition; or, in other embodiments, part of the vertices of the first rib 111 and the vertices of the second rib 112 are set as rounded transitions, for example: the connection between the fourth side 116 of the first rib 111 and the first side 113, and the connection between the second side 114 and the fifth side 117 are set as rounded transitions.

[0095] In other embodiments, the connection between the first side edge 113 and the second side edge 114 may not be provided with an arc chamfer.

[0096] Please refer to Figure 1 In this embodiment, a containing space is formed between the first rib 111 and the second rib 112, specifically, a containing space is formed between the first side 113 and the second side 114 connected to the first side 113; the top cover 010 also includes a second reinforcing rib 120, which is connected to the cover body 100 and is located in the containing space. The second reinforcing rib 120 can further improve the rigidity and strength of the top cover 010, and improve the problem that the top cover 010 is easily sunken, deformed, and damaged due to external forces such as stepping on.

[0097] Furthermore, the top cover plate 010 includes four second reinforcing ribs 120; along the width extension direction of the cover plate body 100, both sides of the second rib portion 112 have accommodation spaces, and each accommodation space is provided with a second reinforcing rib 120, and the second reinforcing rib 120 is also spaced apart from the corresponding second rib portion 112 and the first rib portion 111, that is, the second reinforcing rib 120 is spaced apart from the corresponding first side edge 113 and the second side edge 114. Providing a second reinforcing rib 120 in each accommodation space can also make the force of the top cover plate 010 more balanced and uniform, thereby improving the force strength of the top cover plate 010, thereby improving the problem that the top cover plate 010 is easily dented, deformed, and damaged due to external forces such as stepping. Moreover, the second reinforcing rib 120 is configured to be spaced apart from the corresponding second rib portion 112 and the first rib portion 111, so that a drainage channel can be formed between the first reinforcing rib 110 and the second reinforcing rib 120 to guide the accumulated water on the top cover plate 010 to flow out of the top cover plate 010, thereby improving the rust problem caused by the accumulated water on the top cover plate 010.

[0098] It should be understood that in other embodiments, the second reinforcing rib 120 may be spaced apart from only one of the corresponding second rib portion 112 and the first rib portion 111, and spliced ​​with the other, that is, the second reinforcing rib 120 may be spaced apart from only one of the corresponding first side edge 113 and the second side edge 114, and spliced ​​with the other side.

[0099] Please refer to Figure 1 Optionally, two of the second reinforcing ribs 120 are symmetrically distributed with the other two second reinforcing ribs 120 with the first set axis a as the axis of symmetry, and the extension direction of the first set axis a is the same as the width extension direction of the cover body 100; at the same time, two of the second reinforcing ribs 120 are symmetrically distributed with the other two second reinforcing ribs 120 with the second set axis b as the axis of symmetry, and the extension direction of the second set axis b is the same as the length extension direction of the cover body 100, and the four second reinforcing ribs 120 have the same structural shape and size. Such a setting can not only make the top cover 010 more regular and beautiful in appearance, but also further ensure the force balance of the top cover 010, so as to improve the force strength of the top cover 010 and improve the problem that the top cover 010 is easily sunken, deformed, and damaged due to external forces such as trampling.

[0100] It should be understood that in other embodiments, the four second reinforcing ribs 120 may be arranged in groups of two and symmetrically distributed about the first set axis a or the second set axis b.

[0101] Alternatively, in other embodiments, the top cover plate 010 includes two second reinforcing ribs 120, one second reinforcing rib 120 is disposed in the accommodating space corresponding to one of the first reinforcing ribs 110, and the other second reinforcing rib 120 is disposed in the accommodating space corresponding to the other first reinforcing rib 110, and the two second reinforcing ribs 120 are distributed in a centrally symmetrical manner.

[0102] Alternatively, in other embodiments, four second reinforcing ribs 120 are disposed on the cover body 100 and are symmetrically distributed about the first set axis a and the second set axis b, but the structural shapes and sizes of the four second reinforcing ribs 120 are different.

[0103] Please refer to Figure 1 In this embodiment, the second reinforcing rib 120 includes a first side 121, a second side 122, a third side 123 and a fourth side 124 which are connected end to end in sequence; wherein the first side 121 and the third side 123 both extend along the length extension direction of the cover body 100, the second side 122 is distributed between the first rib portion 111 and the fourth side 124, and the second side 122 is spaced apart from the corresponding first side edge 113, the second side 122 is connected to the first side 121 at an acute angle, and the second side 122 is connected to the third side 123 at an obtuse angle, the fourth side 124 is connected to the first side 121 at an obtuse angle, the fourth side 124 is connected to the third side 123 at an acute angle, and the third side 123 is spaced apart from the corresponding second side edge 114. Such arrangement makes the second reinforcing rib 120 roughly trapezoidal, which can improve the strength and rigidity of the top cover plate 010 and improve the problem that the top cover plate 010 is easily dented, deformed, and damaged due to external forces such as stepping on; and the gap between the second side 122 and the corresponding first side 113, and the gap between the third side 123 and the corresponding second side 114 can be used to guide the accumulated water to flow out of the top cover plate 010, thereby improving the rust problem caused by the accumulation of water in the top cover plate 010.

[0104] Furthermore, the first side 121 of the second reinforcing rib 120 is spaced apart from the long side 101 of the cover plate body 100 to ensure the strength and rigidity of the top cover plate 010 .

[0105] Please refer to Figure 1 and Figure 3The specific shape of the second reinforcing rib 120 can be selected as needed. For example, the angle θ2 between the second side 122 and the width extension direction of the cover body 100 satisfies: 10°≤θ2≤30°; the angle θ3 between the fourth side 124 and the width extension direction of the cover body 100 satisfies: 10°≤θ3≤30°. Optimizing the angles between the second side 122 and the fourth side 124 of the second reinforcing rib 120 and the width extension direction of the cover body 100 can, on the one hand, improve the problem of stress concentration, ensure the strength and rigidity of the top cover 010, and further improve the problem that the top cover 010 is easily sunken, deformed, and damaged due to illegal external forces such as trampling. On the other hand, it is convenient to use the second side 122 and the fourth side 124 to guide the accumulated water on the top cover 010 to flow out of the top cover 010, so as to improve the rust problem caused by the accumulated water on the top cover 010.

[0106] In this embodiment, an angle θ2 between the second side 122 and the width extension direction of the cover body 100 is 10°, and an angle θ3 between the fourth side 124 and the width extension direction of the cover body 100 is 30°.

[0107] It should be understood that in other embodiments, the angle θ2 between the second side 122 and the width extension direction of the cover body 100 can also be 12°, 15°, 18°, 20°, 22°, 25°, 27°, 30°, etc., and the angle θ3 between the fourth side 124 and the width extension direction of the cover body 100 can also be 10°, 12°, 15°, 17°, 20°, 23°, 24°, 27°, 29°, etc., which is not specifically limited here.

[0108] Please refer to Figure 1 and Figure 3 , the size of the second reinforcing rib 120 can be selected as needed, wherein the width of the cover plate body 100 is D, and the length of the cover plate body 100 is L; along the length extension direction of the cover plate body 100, the length of the first side 121 is L3, and the length of the first side 121 satisfies: 1 / 4L≤L3≤1 / 3L; along the width extension direction of the cover plate body 100, the spacing between the first side 121 and the third side 123 is D3, and the spacing between the first side 121 and the third side 123 satisfies: 1 / 4D≤D3≤1 / 3D. Optimizing the length dimension of the first side 121 of the second reinforcing rib 120 and the spacing between the first side 121 and the third side 123 can effectively improve the strength and rigidity of the top cover plate 010, so as to improve the problem that the top cover plate 010 is easily dented, deformed, and damaged due to illegal external forces such as trampling.

[0109] In this embodiment, all vertices of the second reinforcing rib 120 are configured as rounded transitions, specifically, the connection between the first side 121 and the second side 122, the connection between the second side 122 and the third side 123, the connection between the third side 123 and the fourth side 124, and the connection between the fourth side 124 and the first side 121 are all configured as rounded transitions. By configuring the rounded transition, stress concentration can be effectively reduced, thereby improving the problem that the top cover plate 010 is easily dented, deformed, or damaged due to external forces such as stepping on it.

[0110] Of course, in other embodiments, some vertices of the second reinforcement rib 120 are set to be rounded transitions, that is, one, two or three of the connection between the first side 121 and the second side 122, the connection between the second side 122 and the third side 123, the connection between the third side 123 and the fourth side 124, and the connection between the fourth side 124 and the first side 121 are set to be rounded transitions.

[0111] Please refer to Figure 1 The top cover plate 010 of this embodiment also includes a third reinforcing rib 130, which is connected to the cover plate body 100 and is located between the second rib portions 112 of the two first reinforcing ribs 110; two of the four second reinforcing ribs 120 are distributed on one side of the third reinforcing rib 130 in the length extension direction of the cover plate body 100, and the other two of the four second reinforcing ribs 120 are distributed on the other side of the third reinforcing rib 130 in the length extension direction of the cover plate body 100.

[0112] By providing the first reinforcing rib 110, the second reinforcing rib 120, and the third reinforcing rib 130 distributed between the first reinforcing rib 110 and the second reinforcing rib 120, the strength and rigidity of the top cover plate 010 can be greatly improved, so as to fully improve the problem that the top cover plate 010 is easily dented, deformed, and damaged due to external forces such as stepping. Moreover, by providing the first reinforcing rib 110, the second reinforcing rib 120, and the third reinforcing rib 130, the thickness of the cover plate body 100 can be appropriately reduced, so as to ensure the rigidity and strength of the top cover plate 010, and save the input of raw materials used to prepare the top cover plate 010, so as to save costs.

[0113] The shape of the third reinforcing rib 130 can be set as needed. For example, in this embodiment, the third reinforcing rib 130 includes a first arc concave edge 131, a second arc concave edge 132, a third arc concave edge 133 and a fourth arc concave edge 134 connected end to end in sequence, the second arc concave edge 132 faces one of the first reinforcing ribs 110, and is spaced apart from the second rib portion 112 of the corresponding first reinforcing rib 110 and the corresponding two second reinforcing ribs 120. Specifically, the second arc concave edge 132 is spaced apart from the fifth side 117 of one of the first reinforcing ribs 110, and the second arc concave edge 132 is spaced apart from the fourth side 124 of the two second reinforcing ribs 120 on the corresponding side, and the fourth arc concave edge 134 faces the fifth side 117 of the first reinforcing ribs 110. Another first reinforcing rib 110 is arranged at intervals with the second rib 112 of the corresponding first reinforcing rib 110 and the corresponding two second reinforcing ribs 120. Specifically, the fourth arc concave edge 134 is arranged at intervals with the fifth side 117 of another first reinforcing rib 110, and the fourth arc concave edge 134 is arranged at intervals with the fourth side 124 of the two second reinforcing ribs 120 on the corresponding side. The first arc concave edge 131 faces one of the long sides 101 of the cover body 100, and the third arc concave edge 133 faces another of the long sides 101 of the cover body 100. The figure of the third reinforcing rib 130 projected on the cover body 100 is symmetrically distributed with the first set axis a and symmetrically distributed with the second set axis b. Such a setting can improve the overall appearance of the top cover 010 on the one hand, and ensure the strength and rigidity of the top cover 010 on the other hand, and improve the problem that the top cover 010 is easily sunken, deformed, and damaged due to illegal external forces such as trampling. Moreover, the second arc concave edge 132 and the fourth arc concave edge 134 are respectively set to be spaced apart from the corresponding second rib 112 and the second reinforcing rib 120, so as to form a drainage channel to guide the accumulated water on the top cover plate 010 to flow out of the top cover plate 010, so as to improve the rust problem caused by the accumulated water on the top cover plate 010.

[0114] Furthermore, the first arc concave edge 131 is spaced apart from one of the long sides 101 of the cover body 100, and the third arc concave edge 133 is spaced apart from another of the long sides 101 of the cover body 100. Such an arrangement can further ensure the strength and rigidity of the top cover 010.

[0115] Please refer to Figure 1 and Figure 4Optionally, the angle θ4 between the first tangent line tangent to the first arc concave edge 131 and the length extension direction of the cover plate body 100 satisfies: 10°≤θ4≤30°, and the first tangent line is tangent to the end of the first arc concave edge 131 connecting to the second arc concave edge 132; the angle θ5 between the second tangent line tangent to the second arc concave edge 132 and the width extension direction of the cover plate body 100 satisfies: 10°≤θ5≤30°, and the second tangent line is tangent to the end of the second arc concave edge 132 connecting to the first arc concave edge 131. Optimizing the shape structure of the side of the third reinforcing rib 130 can improve the stress concentration problem of the top cover plate 010, thereby improving the strength and rigidity of the top cover plate 010, and improving the problem that the top cover plate 010 is easily sunken, deformed, and damaged due to illegal external forces such as trampling.

[0116] In this embodiment, the angle θ4 between the first tangent line tangent to the first arc concave edge 131 and the length extension direction of the cover body 100 is 10°; the angle θ5 between the second tangent line tangent to the second arc concave edge 132 and the width extension direction of the cover body 100 is 10°.

[0117] Of course, in other embodiments, the angle θ4 between the first tangent line tangent to the first arc concave edge 131 and the length extension direction of the cover body 100 can also be 12°, 15°, 17°, 20°, 23°, 25°, 28°, 30°, etc.; the angle θ5 between the second tangent line tangent to the second arc concave edge 132 and the width extension direction of the cover body 100 can also be 12°, 15°, 17°, 20°, 23°, 25°, 28°, 30°, etc., which is not specifically limited here.

[0118] Please refer to Figure 1 and Figure 4 The size of the third reinforcing rib 130 can be set as needed, wherein the width of the cover body 100 is D, and the length of the cover body 100 is L; the length of the first arc concave edge 131 projected on the long side 101 of the cover body 100 is L4, and L4 satisfies: 1 / 5L≤L4≤1 / 3L; the length of the fourth arc concave edge 134 projected on the short side 102 of the cover body 100 is D4, and D4 satisfies: 4 / 5D≤D4<D. Optimizing the length and width of the third reinforcing rib 130 can improve the strength and rigidity of the top cover 010, and improve the problem that the top cover 010 is easily sunken, deformed, and damaged due to illegal external forces such as trampling.

[0119] In this embodiment, each top end of the third reinforcing rib 130 is configured with a rounded transition, specifically, the connection between the first arc concave edge 131 and the second arc concave edge 132, the connection between the second arc concave edge 132 and the third arc concave edge 133, the connection between the third arc concave edge 133 and the fourth arc concave edge 134, and the connection between the fourth arc concave edge 134 and the first arc concave edge 131 are all rounded transitions. By configuring the rounded transition, stress concentration can be effectively reduced, thereby improving the problem that the top cover plate 010 is easily sunken, deformed, or damaged due to external forces such as stepping on it.

[0120] It should be noted that it can be understood that the first arc concave edge 131 and the second arc concave edge 132 are connected by a rounded transition portion, and the first tangent is specifically tangent to the position where the first arc concave edge 131 is connected to the corresponding rounded transition portion. Similarly, the second tangent is specifically tangent to the position where the second arc concave edge 132 is connected to the corresponding rounded transition portion.

[0121] Of course, in other embodiments, one, two or three of the connection between the first arc concave edge 131 and the second arc concave edge 132, the connection between the second arc concave edge 132 and the third arc concave edge 133, the connection between the third arc concave edge 133 and the fourth arc concave edge 134, and the connection between the fourth arc concave edge 134 and the first arc concave edge 131 are rounded transitions.

[0122] The starting angles of the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 can be selected as needed. For example, the starting angle of at least one of the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 is 45°-60°. By optimizing the starting angle of the reinforcing rib, when the reinforcing rib is subjected to external force, the external force can be effectively diffused, the local pressure can be reduced, and the overall structural strength of the top cover plate 010 can be improved, so as to improve the problem that the top cover plate 010 is easily dented, deformed, and damaged due to external forces such as trampling.

[0123] Please refer to Figure 5 In this embodiment, the starting angles of the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 are 45°. Figure 5 Only the rib angle θ6 of the second reinforcing rib 120 is shown.

[0124] Of course, in other embodiments, the starting angles of the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 can also be 46°, 48°, 50°, 53°, 55°, 57°, 60°, etc., which are not specifically limited here.

[0125] It should be understood that in the present embodiment, the rib starting angles of the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 are the same in size. In other embodiments, the rib starting angles of the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 may also be different in size, which is not specifically limited herein.

[0126] It should be noted that the rib angle refers to the angle formed between the hypotenuse connecting any one of the first reinforcing rib 110 , the second reinforcing rib 120 and the third reinforcing rib 130 to the cover body 100 and the horizontal plane of the cover body 100 .

[0127] The thickness of the cover plate body 100, the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 can be selected as needed. For example, the thickness of the cover plate body 100 is greater than or equal to 0.5 mm, and the thickness of at least one of the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 satisfies: 5 mm ≤ H ≤ 8 mm. Optimizing the thickness of the reinforcing rib and the cover plate body 100 can ensure the strength and rigidity of the top cover plate 010 on the one hand, improve the problem that the top cover plate 010 is easily dented, deformed, and damaged by impacts such as being stepped on, and on the other hand, effectively control the input amount of raw materials for producing the top cover plate 010, thereby achieving the purpose of controlling and reducing the production cost of the top cover plate 010.

[0128] Please refer to Figure 5 and Figure 6 In this embodiment, the thickness of the cover body 100 is 0.6 mm, and the thickness H of the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 are all 7 mm.

[0129] Of course, in other embodiments, the thickness of the cover body 100 can also be 0.5 mm, 0.7 mm, 0.8 mm, etc., and the thickness H of at least one of the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 is 5 mm, 6 mm, 8 mm, etc., which is not specifically limited here.

[0130] It should be noted that the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 of the top cover plate 010 of this embodiment can be directly stamped on the cover plate body 100, so that the top cover plate 010 is an integral part, thereby ensuring the strength and rigidity of the structure of the top cover plate 010. Of course, in other embodiments, the first reinforcing rib 110, the second reinforcing rib 120 and the third reinforcing rib 130 can also be cast and formed synchronously with the cover plate body 100, which is not specifically limited here.

[0131] It should also be noted that the drainage channel formed by the second side 122 of the second reinforcement rib 120 and the first side 113 of the first reinforcement rib 110, the drainage channel formed by the second arc concave edge 132 and the corresponding first reinforcement rib 110 and second reinforcement rib 120, and the drainage channel formed by the fourth arc concave edge 134 and the corresponding first reinforcement rib 110 and second reinforcement rib 120 extend as a whole along the width extension direction of the cover body 100, shortening the path for the top cover plate 010 to discharge accumulated water, which is conducive to more efficient discharge of accumulated water and improving the problem of rust on the top cover plate 010 caused by accumulated water.

[0132] The middle part of the top cover plate 010 of the present embodiment has a roughly star-shaped third reinforcing rib 130, and is provided with four roughly trapezoidal second reinforcing ribs 120, and two symmetrically distributed roughly T-shaped first reinforcing ribs 110, which greatly improves the strength and rigidity of the top cover plate 010. CAE simulation verification shows that under the same material thickness conditions, its rigidity is significantly improved. After jumping and stepping tests, it is verified that the top cover plate 010 has no obvious deformation.

[0133] In summary, the top cover plate 010 of the utility model can be used for air conditioners, and the top cover plate 010 greatly improves strength and rigidity, ensuring that there will be no obvious deformation under conditions of being stepped on and dropped during transportation; the thickness can be appropriately reduced while ensuring the strength and rigidity of the top cover plate 010, thereby saving material costs. The top cover plate 010 can also efficiently and reliably drain accumulated water, effectively improving the problem of accumulated water rust.

[0134] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
