Description

Technical Field

[0002] RV air conditioners are installed on the roof of the RV, so the bottom shell of the air conditioner is the main load-bearing component. In order to achieve lightweight RV air conditioners, related technologies use foam materials as the bottom shell of the air conditioner, and use screws to fix the fan, compressor and other refrigeration system components to the bottom shell. However, the foam material has low hardness. When the vehicle is violently bumpy, the refrigeration system components fixed on the bottom shell are easily damaged by the foam material, resulting in damage to the fixed structure, or the foam material is damaged at the screw fixing point, causing the compressor and other refrigeration system components to detach from the bottom shell.

[0069] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0070] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0071] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0072] It should be noted that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary and should not constitute any limitation to the present application.

[0073] RV air conditioners are installed on the roof of the RV, so the bottom shell of the air conditioner is the main load-bearing component. In order to achieve lightweight RV air conditioners, related technologies use foam materials as the bottom shell of the air conditioner, and use screws to fix the fan, compressor and other refrigeration system components to the bottom shell. However, the hardness of the foam material is low. When the vehicle is violently bumpy, the refrigeration system components fixed on the bottom shell are easily damaged, causing the local foam material to be damaged, resulting in the destruction of the fixed structure, or the foam material at the screw fixing point is damaged, causing the compressor and other refrigeration system components to detach from the bottom shell.

[0074] In view of this, an embodiment of the present application provides a bottom shell assembly, which is applied to a motorhome air conditioner. The motorhome air conditioner is configured to be installed on the roof, and the bottom shell assembly includes a shell, a foam piece and a fixing piece. The shell has a mounting groove, and the foam piece is arranged in the mounting groove and connected to the shell. The foam piece has a first surface and a second surface arranged opposite to each other, and the first surface faces the bottom of the mounting groove. The fixing piece includes a first fixing plate and a connecting piece, the first fixing plate is arranged on the first surface, the connecting piece is connected to the first fixing plate and passes through the foam piece, and the connecting piece is configured to be connected to a refrigeration system component inside the motorhome air conditioner, so that the first fixing plate cooperates with the refrigeration system component to clamp the foam piece.

[0075] The bottom shell assembly mentioned above, through the first fixing plate and the refrigeration system component to clamp the foamed part, improves the structural strength of the bottom shell assembly, so that the connection between the refrigeration system component and the bottom shell assembly is not easily damaged. At the same time, by arranging the foamed part in the installation groove of the shell and connecting it to the shell, the vibration generated by the refrigeration system component is evenly transmitted through the foamed part clamped by the fixing part and the external shell, which can fully absorb the vibration generated by the refrigeration system component, thereby reducing the impact force of the refrigeration system component on the bottom shell assembly, reducing the risk of damage to the structure of the RV air conditioner, and ensuring the working reliability of the RV air conditioner.

[0076] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0077] like Figures 1 to 3 As shown, the embodiment of the present application provides a bottom shell assembly 100 and a motorhome air conditioner 200, wherein the motorhome air conditioner 200 comprises a bottom shell assembly 100, an upper shell 201, refrigeration system components, and an indoor unit 202. The bottom shell assembly 100 is connected to the upper shell 201, and encloses an installation space 2011, in which the refrigeration system components of the motorhome air conditioner 200 are located.

[0078] See also Figure 3 In some embodiments, the bottom shell assembly 100, the upper shell 201, and the refrigeration system components constitute the external unit of the RV air conditioner 200, the external unit is arranged on the roof and is located outside the vehicle, and the internal unit 202 is arranged on the roof and is located inside the vehicle. The refrigeration system components inside the RV air conditioner 200 include but are not limited to the evaporator 203, the condenser 204, the electric control box 205, the front fan 206, the rear fan 207, the compressor 208 and other components.

[0079] See also Figure 4 , Figure 5 and Figure 6 In some embodiments, the bottom shell assembly 100 is mounted on the roof of the RV. The bottom shell assembly 100 includes a shell 10, a foam member 20 and a fixing member 30. The shell 10 has a mounting groove 11, and the foam member 20 is disposed in the mounting groove 11 and connected to the shell 10. The foam member 20 has a first surface 21 and a second surface 22 disposed opposite to each other, and the first surface 21 faces the bottom of the mounting groove 11. The fixing member 30 is disposed on the foam member 20 and is used to fix the refrigeration system components.

[0080] The refrigeration system components are fixed by the fixing member 30, and then installed on the roof by the bottom shell assembly 100, so that the RV air conditioner 200 is installed and fixed on the roof. The foam member 20 has low hardness and light weight. By setting the foam member 20 in the installation groove 11 of the shell 10 and connecting it to the shell 10, on the one hand, the overall weight of the bottom shell assembly 100 can be reduced, and on the other hand, the vibration generated by the refrigeration system components is evenly transmitted through the fixing member 30, the foam member 20 and the external shell 10, which can fully absorb the vibration generated by the refrigeration system components, thereby reducing the impact force of the refrigeration system components on the bottom shell assembly 100, reducing the risk of damage to the structure of the RV air conditioner 200, and ensuring the working reliability of the RV air conditioner 200.

[0081] In some embodiments, the mounting groove 11 is located on the side of the housing 10 facing the mounting space 2011, and the inner surface of the mounting groove 11 is connected to the outer surface of the foam part 20 by bonding. Specifically, the housing 10 and the foam part 20 are connected by high-strength glue. The high-strength glue can not only make the housing 10 and the foam part 20 firmly connected, but also reduce the gap between the housing 10 and the foam part 20, improve the integrity of the housing 10 and the foam part 20, and make the housing 10 and the foam part 20 not easy to shake relative to each other. After the bottom shell assembly 100 is subjected to force, the overall deformation is small, and the probability of damage by external force impact is reduced. After the bottom shell assembly 100 is installed on the roof, the roof and the housing 10 cooperate to wrap the foam part 20, and the foam part 20 has no directly exposed part, which reduces the risk of long-term erosion by the external environment.

[0082] See also Figures 5 to 7 In some embodiments, the housing 10 includes a bottom plate 12 and a side plate 13. The side plate 13 is disposed around the bottom plate 12 and together with the bottom plate 12, forms a mounting groove 11. The bottom plate 12 forms the bottom of the mounting groove 11. The side of the bottom plate 12 facing away from the mounting groove 11 is configured to be mounted on the roof. The bottom plate 12 has a hollow portion 121. A portion of the foaming member 20 is exposed through the hollow portion 121, so that the portion of the foaming member 20 exposed in the hollow portion 121 contacts the roof.

[0083] The hollow portion 121 reduces the weight of the housing 10, thereby helping to reduce the overall weight of the bottom housing assembly 100. Part of the foam member 20 can contact the roof through the hollow portion 121, so that the foam member 20 and the housing 10 can jointly bear the weight of the refrigeration system components and transfer the carried weight to the roof.

[0084] In some embodiments, the housing 10 is a plastic housing. The structural strength of the plastic housing is higher than that of the foam part 20, and the weight is relatively light. The plastic housing 10 is disposed outside the foam part 20, which can reduce the weight of the bottom housing assembly 100 to a certain extent, provide protection for the foam part 20, and reduce the damage of the foam part 20 caused by external impact. It can also improve the overall toughness of the bottom housing assembly 100 while ensuring the structural strength of the bottom housing assembly 100, and can cooperate with the foam part 20 to improve the structural strength and shock absorption performance of the bottom housing assembly 100 while reducing the weight of the whole machine.

[0085] See also Figure 4 In some embodiments, a protrusion 23 is formed on the second surface 22 of the foam member 20. The protrusion 23 is configured to fit with a refrigeration system component to limit the movement of the refrigeration system component.

[0086] When the refrigeration system components inside the RV air conditioner 200 are mounted on the second surface 22 through the fixing member 30, they can also be contacted and fitted with the raised portion 23 to limit their own movement, thereby further improving the stability of the installation of the refrigeration system components. In addition, the raised portion 23 can absorb the vibration of the refrigeration system components and reduce the impact of the refrigeration system components.

[0087] For example, in some embodiments, the protrusion 23 is used to fix the front fan 206, and the outer wall of the front fan 206 is an outwardly convex arc surface. The protrusion 23 has a contour surface 231, and the anti-contact surface is an inwardly concave arc surface, so as to fit the outer wall of the front fan 206. The front fan 206 is fixed by the fixing member 30 and the protrusion 23, which improves the installation stability of the front fan 206 and can reduce the vibration and noise generated when the front fan 206 is running.

[0088] See also Figure 4 In some embodiments, the second surface 22 of the foam member 20 is provided with a drainage groove 24, which is in communication with the external environment. The drainage groove 24 can collect condensed water formed on the outer wall of the refrigeration system components and discharge the condensed water to the outside of the RV air conditioner 200. For example, the drainage groove 24 is provided below the evaporator 203 and the condenser 204 to collect the condensed water dripping from the outer surface of the evaporator 203 and the condenser 204, and discharge it to the outside of the RV air conditioner 200.

[0089] It is understandable that the drainage groove 24 may be provided by directly cutting excess foaming part 20 on the second surface 22 .

[0090] In some embodiments, the foaming member 20 is a foamed polypropylene board or a foamed polystyrene board. Both the foamed polypropylene board and the foamed polystyrene board have the advantages of light weight, buffering, insulation, corrosion resistance, low price, etc., which are conducive to improving the shock absorption performance, light weight, corrosion resistance and other reliability of the RV air conditioner 200.

[0091] See also Figure 5 and Figure 7 In some embodiments, the foaming member 20 has an air outlet 25 and an air inlet 26, which are exposed through the hollow portion 121 and are connected to the indoor unit 202. The air outlet 25 allows the hot air in the RV to flow into the indoor unit 202 after passing through the indoor unit 202, and then flows into the vehicle after being cooled by the evaporator 203 to form cold air through the air inlet 26 into the indoor unit 202.

[0092] See also Figure 4 , Figure 5 and Figure 7 In some embodiments, the fixing member 30 includes a first fixing plate 31 and a connecting member 32. The first fixing plate 31 is disposed on the first surface 21. The connecting member 32 connects the first fixing plate 31 and passes through the foaming member 20. The connecting member 32 is configured to be connected to a refrigeration system component so that the first fixing plate 31 cooperates with the refrigeration system component to clamp the foaming member 20.

[0093] The first fixing plate 31 cooperates with the refrigeration system components inside the RV air conditioner 200 to clamp the foam part 20, so that the vibration generated by the refrigeration system components can be evenly transmitted to the entire foam part 20, thereby improving the structural strength of the bottom shell assembly 100 and preventing the connection between the refrigeration system components in the RV air conditioner 200 and the bottom shell assembly 100 from being easily damaged.

[0094] In some embodiments, the first fixing plate 31 is a sheet metal component or other component having a structural strength greater than the foam component 20 , so as to cooperate with the foam component 20 to improve the overall structural strength of the bottom shell assembly 100 .

[0095] Continue reading Figure 4 , Figure 5 and Figure 7 In some embodiments, the first fixing plate 31 is exposed outside the housing 10 through the hollow portion 121. The hollow portion 121 reduces the shielding of the second surface 22 by the housing 10, so that the first fixing plate 31 can be installed on the second surface 22 of the foam member 20 through the hollow portion 121, so that after the foam member 20 is installed on the housing 10, the first fixing plate 31 can also be installed on the foam member 20.

[0096] In some embodiments, the connector 32 is a screw rod, and the refrigeration system component is threadedly connected to the screw rod. In other embodiments, the connector 32 may also include a connecting rod and a nut, and the refrigeration system component is fixed to the connecting rod by the nut.

[0097] See also Figure 4 and Figure 5In some embodiments, the fixing member 30 further includes a second fixing plate 33, the second fixing plate 33 is disposed on the second surface 22, the connecting member 32 connects the first fixing plate 31 and the second fixing plate 33, and the second fixing plate 33 is configured to install refrigeration system components.

[0098] The connecting member 32 is connected to the refrigeration system components through the second fixing plate 33, so that the side where the first surface 21 of the foam member 20 is located is clamped by the first fixing plate 31, and the side where the second surface 22 of the foam member 20 is located is clamped with the refrigeration system components inside the RV air conditioner 200 through the second fixing plate 33. That is, the foam member 20 is clamped by the first fixing plate 31 and the second fixing plate 33, and the clamping area is not limited by the outer contour of the refrigeration system components, thereby further improving the structural strength of the foam member 20, so that the position where the foam member 20 is installed with the refrigeration system components inside the RV air conditioner 200 is not easily damaged.

[0099] In some embodiments, the second fixing plate 33 is a sheet metal component or other component having a structural strength greater than the foam component 20 , so as to cooperate with the foam component 20 to improve the overall structural strength of the bottom shell assembly 100 .

[0100] Continue reading Figure 4 , Figure 5 and Figure 8 In some embodiments, the second fixing plate 33 includes a first connecting section 331 and a second connecting section 332 connected to each other, wherein the first connecting section 331 is connected to the connecting member 32 and is disposed on the second surface 22. The second connecting section 332 is perpendicular to the first connecting section 331 and extends in a direction away from the second surface 22, and is used to install refrigeration system components.

[0101] The connecting member 32 connects the first fixing plate 31 and the first connecting section 331, so that the first connecting section 331 cooperates with the first fixing plate 31 to clamp the foam member 20, thereby improving the structural strength of the foam member 20. The second connecting section 332 extends away from the second surface 22, thereby providing a space for installing the refrigeration system components, and facilitating the installation of the refrigeration system components on the second connecting section 332.

[0102] Further, the first connecting section 331 can be selected to be substantially parallel to the second surface 22 and to be attached to the second surface 22. The connecting member 32 connects the first fixing plate 31, the foaming member 20 and the first connecting section 331 in a direction substantially perpendicular to the second surface 22. The refrigeration system component installed on the second connecting section 332 is located on a side of the second connecting section 332 away from the connecting member 32, and the second connecting section 332 is connected to the refrigeration system component by bolts, and the bolts connect the second connecting section 332 and the refrigeration system component in a direction substantially parallel to the second surface 22. This arrangement makes it difficult to be interfered by the connecting member 32 when installing the refrigeration system component.

[0103] In some embodiments, the second connection section 332 is provided with a avoidance groove 3321, and the avoidance groove 3321 is used to avoid the refrigeration system components installed on the second connection section 332. For example, the second connection section 332 is used to install the rear fan 207, and the rear fan 207 is generally cylindrical. When the rear fan 207 is installed on the second connection section 332, the avoidance groove 3321 is generally semicircular, so as to facilitate avoiding the vent of the rear fan 207.

[0104] See also Figure 3 and Figure 4 In some embodiments, the fixing member 30 also includes a third fixing plate 34 and a connecting column (not shown) connected to each other, the third fixing plate 34 is connected to the second surface 22, the connecting column is configured to pass through the first surface 21 from the second surface 22, and is used to connect the indoor unit 202 of the RV air conditioner 200.

[0105] The third fixing plate 34 is disposed on the second surface 22 , and by cooperating with the connecting member 32 , the bottom shell assembly 100 can be connected to the internal unit 202 disposed inside the RV. The third fixing plate 34 can evenly transmit the force to the foam part 20 , thereby reducing the risk of damage to the foam part 20 .

[0106] In some embodiments, the third fixing plate 34 is a sheet metal component or other component having a structural strength greater than the foam component 20 , so as to cooperate with the foam component 20 to improve the overall structural strength of the bottom shell assembly 100 .

[0107] See also Figure 3 and Fig. 9 In some embodiments, the fixing member 30 further includes an elastic member 35, one end of the connecting member 32 extends out of the second surface 22, the elastic member 35 is sleeved on the portion of the connecting member 32 extending out of the second surface 22, the elastic member 35 is located between the second surface 22 and the refrigeration system component, and the elastic member 35 is configured to support the refrigeration system component.

[0108] The elastic member 35 can generate compression deformation under the gravity of the refrigeration system components. When the RV air conditioner 200 vibrates, the elastic member 35 can absorb the vibration of the refrigeration system components through its own elastic deformation, thereby playing a shock-absorbing role.

[0109] For example, the elastic member 35 is a metal spring, or a rubber elastic sleeve or other component with elastic deformation function.

[0110] In some embodiments, the compressor 208 is mounted on the foaming member 20 through the elastic member 35. The compressor 208 includes a mounting plate 2081, which is sleeved on one end of the connecting member 32 away from the second surface 22, and the elastic member 35 is mounted on the connecting member 32 through a nut, so that the elastic member 35 is located between the second surface 22 and the mounting plate 2081. The compressor 208 transmits its own gravity to the elastic member 35 through the mounting plate 2081, so that the elastic member 35 is compressed and deformed to absorb the vibration of the compressor 208.

[0111] In some embodiments, a plurality of fixing members 30 are provided, and each refrigeration system component is mounted on the foam member 20 via at least one fixing member 30 .

[0112] The RV air conditioner 200 in the present application can transfer its own weight to the roof through the bottom shell assembly 100. The bottom shell assembly 100 can improve the overall structural strength of the RV air conditioner 200 and help reduce the weight of the RV air conditioner 200. After the upper shell 201 is connected to the bottom shell assembly 100, they can jointly provide protection for the refrigeration system components disposed inside the RV air conditioner 200.

[0113] In addition, those skilled in the art may also make other changes in the present application. Of course, these changes made based on the present application should be included in the scope disclosed in the present application.
