Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, specifically to an air conditioning box body and an automotive air conditioning box. Background Technology

[0002] Currently, automotive HVAC recirculation vents commonly use parallel ribbed grilles. This structure is injection molded as a single unit, with the grille area serving both airflow guidance and protection functions. The perimeter overlaps with the housing frame and is secured with screws or clips. Due to the thinness of the ribs, the overall rigidity of the part is relatively low, often resulting in a "soft" appearance after assembly. Under conditions such as transportation, vehicle vibration, or temperature changes, the grille is prone to warping and causing housing deformation. Housing deformation reduces the damper's movement clearance, leading to scraping between the damper edge and the inner wall, producing harsh noise, and accelerating the wear of the sealing sponge. Long-term operation may result in problems such as incomplete closure and airflow leakage. Utility Model Content

[0003] The purpose of this utility model is to provide an air conditioning box body and an automotive air conditioning box, which can improve the overall rigidity, avoid the situation of being too soft after assembly, effectively suppress warping caused by transportation and vehicle vibration, thereby avoiding the shell being stretched and deformed. Thus, it can avoid the edge of the damper scraping against the inner wall and producing a harsh noise, and at the same time, it can avoid the sealing structure from failing to close properly and causing air leakage due to excessive wear.

[0004] The embodiments of this utility model can be implemented as follows: In the first aspect, this utility model provides an air conditioning box body, the air conditioning box body including the main body having multiple grille holes distributed at the internal circulation air outlet, each grille hole being formed by multiple slats connected to each other or connected to the main body; Each slat is reinforced with ribs along its extension direction.

[0005] In an optional embodiment, the reinforcing ribs on each slat are disposed on the outer surface of the slat.

[0008] In an optional embodiment, multiple slats corresponding to the same grid hole are arranged at an angle, and some of the reinforcing ribs converge at the corner of the grid hole.

[0009] In an optional implementation, the reinforcing ribs on each slat are provided on the side of the slat.

[0010] In an optional implementation, multiple slats corresponding to the same grid opening are located inside the grid opening.

[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] Please refer to Figures 1-5 This embodiment provides an air conditioning unit body 100. The air conditioning unit body 100 includes a main body with multiple grille holes 111 distributed at the internal circulation air outlet 110. Each grille hole 111 is formed by multiple slats 112 connected to each other or connected to the main body. Each of the slats 112 is provided with a reinforcing rib 120 along its extension direction.

[0025] Please refer to Figures 1-5 The working principle of the air conditioning unit body 100 is as follows: The air conditioning unit 100 includes a main body with multiple grille holes 111 distributed at the internal circulation air outlet 110. Each grille hole 111 is formed by multiple slats 112 connected to each other or to the main body. Each slat 112 is provided with a reinforcing rib 120 along its extension direction. It should be noted that the reinforcing ribs 120 are arranged according to the position of the slats 112, so that each slat 112 is correspondingly provided with a reinforcing rib 120 to enhance its structural strength. In this way, the structural strength of the internal circulation air outlet 110 of the air conditioning unit 100 is improved.

[0026] Please refer to Figures 1-5 In this embodiment, when configuring the reinforcing rib 120, a continuous flange is added to the original grille bars 112, while the thickness of the rib is reduced. This structural arrangement allows the flange and bars 112 to be injection molded in one piece, forming a closed "U"-shaped reinforcing frame, thus increasing the in-plane bending moment of the grille. It should also be noted that this arrangement, by adding the reinforcing rib 120 and reducing the thickness of the original bars 112, significantly enhances the overall structural rigidity while maintaining a relatively constant part weight. After assembly, the "softness" phenomenon is eliminated, effectively suppressing warping caused by transportation and vehicle vibration, thereby preventing the shell from being stretched and deformed.

[0027] It should be noted that, in this embodiment, taking the original slat 112 thickness of 2mm as an example, when adding the reinforcing rib 120, a 1mm continuous flange can be set on the original slat 112 to form the 1mm reinforcing rib 120. Furthermore, when configuring the reinforcing rib 120, the thickness of the slat 112 can be reduced to 1.5mm. In this way, the reinforcing rib 120 can be added while reducing the original thickness of the slat 112, thereby significantly enhancing the overall structural rigidity while maintaining the basic weight of the part. Moreover, taking the above structural configuration as an example, after thinning the slat 112 by 0.5mm, the material consumption per part is reduced by approximately 8%, thereby reducing raw material costs; simultaneously, the injection molding cycle is shortened by 5%, improving production efficiency. Furthermore, through the structural arrangement of the aforementioned reinforcing ribs 120, the overall structural rigidity of the internal circulation air outlet 110 can be significantly enhanced, thereby enabling control over its deformation during use. Taking the setting of the aforementioned reinforcing ribs 120 to control the shell deformation to within 0.3mm as an example, this arrangement ensures that the gap between the damper and the inner wall is always greater than 1mm, thus completely eliminating the risk of scratching during operation.

[0028] In summary, the air conditioning unit 100 is applied to the automotive air conditioning unit 200, which can improve the overall rigidity and prevent the unit from becoming too soft after assembly. It can effectively suppress warping caused by transportation and vehicle vibration, thereby preventing the housing from being stretched and deformed. As a result, it can prevent the edge of the damper from scraping against the inner wall and producing a harsh noise. At the same time, it can prevent the sealing structure from failing due to excessive wear, resulting in the damper not closing properly and air leakage.

[0029] Further, please refer to Figures 1-5 In this embodiment, the position of the reinforcing ribs 120 on the slats 112 can be adjusted according to usage requirements. In this embodiment, the reinforcing ribs 120 on each slat 112 are all located on the outer surface of the slat 112. This arrangement aims to reduce the overall manufacturing difficulty, lower manufacturing costs, and improve manufacturing efficiency. Furthermore, based on the above, with the reinforcing ribs 120 present, the slats 112 can be reduced in size relative to their original dimensions to maintain overall structural quality. In this embodiment, the thickness is reduced. Based on this, while satisfying the above-mentioned increase in structural strength, the width of the reinforcing rib 120 on each slat 112 can be smaller than the width of the slat 112, and the thickness of the reinforcing rib 120 on each slat 112 can be less than or equal to the thickness of the slat 112. Through this arrangement, the structure of the reinforcing rib 120 can be simplified, and the structure of the reinforcing rib 120 and the slat 112 can be optimized, improving their integrity and integration. Thus, while meeting the above-mentioned structural requirements, the manufacturing difficulty and cost can be reduced.

[0030] Further, please refer to Figures 1-5 In this embodiment, the grid holes 111 at the internal circulation air vent 110 are hexagonal holes. Therefore, the multiple slats 112 corresponding to the same grid hole 111 are set at an angle, and some of the reinforcing ribs 120 converge at the corner of the grid hole 111. In this way, the multiple grid holes 111 at the internal circulation air vent 110 are combined into a honeycomb structure, which can cooperate with the aforementioned reinforcing ribs 120 to improve the structural strength of the internal circulation air vent 110.

[0031] Unlike the method described above where the reinforcing ribs 120 are disposed on the outer surface of each grille 112, in other embodiments of this invention, when configuring the reinforcing ribs 120, they can also be disposed on the side of each grille 112 as needed. Based on this, multiple grilles 112 corresponding to the same grille hole 111 are located inside the grille hole 111. This arrangement satisfies the aforementioned requirement to increase the structural strength of the internal circulation air vent 110.

[0032] Based on the above, please refer to Figures 1-5 In this embodiment, the air conditioning unit body 100 is manufactured by integrating the main body, multiple slats 112 and multiple reinforcing ribs 120 into one piece. The purpose is to reduce the manufacturing difficulty, improve production efficiency and reduce the cost of manufacturing and use.

[0033] Based on the above structure, in order to improve the structural strength of the internal circulation air outlet 110 when configuring the main body, this embodiment can also make the main body equipped with a reinforcing rib 130, which is set along the edge of the internal circulation air outlet 110.

[0034] Based on the above, please refer to Figures 1-5 This embodiment also provides an automotive air conditioning unit 200, which includes the aforementioned air conditioning unit body 100. The automotive air conditioning unit 200 uses the aforementioned air conditioning unit body 100 and assembles it with other unit components; therefore, it possesses all the advantages of the aforementioned air conditioning unit body 100, which will not be elaborated further here.

[0035] The above are merely specific embodiments 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.
