[0058] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0059] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0060] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0061] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0062] The utility model provides a shell component and an air conditioner, wherein the shell component is applied to the air conditioner.

[0063] It should be noted that the air conditioner provided by the utility model refers to a portable air conditioner suitable for use at home or in the office, or an air conditioner installed in a mobile house or a container house, or an RV air conditioner installed in a RV. It is understandable that the utility model does not limit the specific use of the air conditioner. For ease of understanding, the following description will take the installation of the air conditioner in a RV as an example.

[0064] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic structural diagram of the housing assembly of an embodiment of the utility model at a first viewing angle. Figure 2 The exploded view of the housing assembly of the embodiment of the utility model is as follows. The housing assembly 10 includes a housing cover 100 and an adapter box 200 .

[0065] The shell cover 100 is used to form a part of the air conditioner shell. The shell cover 100 is used to cooperate with other shell structures to seal the air conditioner's electronic control equipment, refrigeration components, functional devices, etc. inside the air conditioner. At the same time, the shell cover 100 can be used to position, support and connect the above devices inside the air conditioner. For example, the shell cover 100 can be used as an installation panel of the air conditioner. When the air conditioner is installed on the roof of a motorhome, the side of the shell cover 100 facing the inside of the motorhome is used as the main appearance surface of the air conditioner. The shell cover 100 can be provided with an air outlet structure and an air return structure.

[0066] Please refer to Figure 3 , Figure 3The housing cover 100 is provided with an air outlet channel 100d and an air outlet 100c connected to the air outlet channel 100d, and an air outlet grille is provided at the air outlet 100c to guide the airflow after heat exchange in the refrigeration component to flow in a certain direction.

[0067] The shell cover 100 is provided with a return air passage 100b and a return air port 100a connected to the return air passage 100b, and the return air port 100a is connected to the outside of the shell cover 100. It should be noted that the "outside of the shell" here needs to be determined according to the specific purpose of the air conditioner. For example, when the air conditioner is installed in a motorhome, the outside of the shell cover 100 refers to the air environment inside the motorhome, and the return air passage 100b is connected to the air environment inside the motorhome, so that the air in the motorhome enters the inside of the air conditioner through the return air passage 100b, and after heat exchange through the refrigeration component in the air conditioner, it is blown into the motorhome from the air outlet 100c to realize internal circulation.

[0068] It can be understood that the air conditioner can also be provided with an air inlet channel, which can be connected to the air environment outside the RV, so that the air outside the RV enters the air conditioner through the air inlet channel, and after heat exchange through the refrigeration components in the air conditioner, it is blown into the RV from the air outlet 100c to realize external circulation.

[0069] The adapter box 200 is used to electrically connect the electric control components in the air conditioner with an external power supply, and a circuit structure for connecting the electric control components may be provided in the adapter box 200. Specifically, when the air conditioner is installed in a motorhome, the adapter box 200 is used to electrically connect the electric control components of the air conditioner with a power module in the motorhome to convert the built-in power supply of the motorhome into the power supply required by the air conditioner.

[0070] like Figure 1 As shown, the shell assembly 10 also includes an electric control junction box 300, which is installed on the shell cover 100. The electric control junction box 300 is provided with electric control components such as a control main board for controlling the operation of the air conditioner. The adapter box 200 is used to electrically connect to the electric control components in the electric control junction box 300 through a wiring harness.

[0071] In the related art, the electric control adapter box of the RV air conditioner is usually installed inside the air conditioner, and the air conditioner cannot be fully installed in advance. After assembling the electric control adapter box, the shell needs to be assembled. However, the installation space in the RV is limited, which causes great inconvenience to the installation.

[0072] To solve the above problem, in the embodiment of the present invention, the adapter box 200 is connected to the housing cover 100 and is disposed in the return air passage 100b.

[0073] The embodiment of the utility model sets the adapter box 200 in the return air duct 100b. When installing the adapter box 200, the adapter box 200 can be directly sent into the return air duct 100b through the return air port 100a for installation. Then the whole air conditioner can be pre-assembled into a nearly complete structure, and only the return air port 100a needs to be kept in an exposed state, that is, when installing the adapter box 200, there is no need to install or disassemble the air conditioner shell, so that the adapter box can be easily assembled under the limited space conditions of the RV. Moreover, when the adapter box 200 needs to be maintained later, the hand can be directly inserted into the return air duct 100b to disassemble the adapter box 200 and take it out from the return air port 100a, without the need to disassemble the air conditioner shell on a large scale (for example, there is no need to disassemble the shell cover 100), which can facilitate maintenance.

[0074] At the same time, since the adapter box 200 is arranged in the return air channel 100b, that is, on the air flow path, during the operation of the air conditioner, the air entering from the return air channel 100b can take away the heat generated by the electronic control of the adapter box 200, and the adapter box 200 can be cooled and cooled. There is no need to additionally set up a cooling fan for the adapter box 200, which can reduce costs.

[0075] Please combine Figure 3 And refer to Figure 4 , Figure 4 The schematic diagram of the partial structure of the air conditioning assembly of the embodiment of the utility model is cut away. The housing cover 100 includes an air guide frame 110 surrounding the return air channel 100b.

[0076] The air guide frame 110 may include a plurality of walls around it, and the plurality of walls are connected and enclosed to form a specific shape of the return air channel 100b to guide the air entering from the return air port 100a to flow along the return air channel 100b. The air guide frame 110 may be integrally formed with the housing cover 100, or may be a separate connection structure with the housing cover 100.

[0077] In one embodiment, the housing cover 100 includes a first wall forming the return air channel 100 b , and the adapter box 200 includes a first buckle, which is engaged with the first wall. The first wall may be any wall on the air guide frame 110 .

[0078] Then, by setting the first buckle to be engaged with the first wall, that is, in this embodiment, the adapter box 200 is engaged with the shell cover 100, and the installation and disassembly process is simple. Compared with the traditional air conditioner in which the electric control box is connected and fixed by screws, the screw connection step is omitted, and the installation and disassembly process does not require the use of tools, which can improve the installation or disassembly efficiency. In particular, when the air conditioner is installed in a motorhome, the operator only needs to manually send the adapter box 200 from the return air port into the return air channel and engage the adapter box 200 with the first wall, without having to look up and screw upwards, which reduces the difficulty of the installation operation and further facilitates the assembly of the adapter box 200.

[0079] In one embodiment, if Figure 3 and Figure 4 As shown, the first wall 111 extends axially along the return air channel 100 b , and the first buckle 211 is engaged with the first wall 111 .

[0080] Please refer to Figure 5 , Figure 6 and Figure 7 , Figure 5 This is a cut-away cross-sectional view of a housing assembly according to an embodiment of the present utility model. Figure 6 This is a schematic diagram of the structure of the adapter box of the housing assembly of the embodiment of the utility model. Figure 7 for Figure 5 The first buckle 211 includes a first connecting portion 2111 and a first hook portion 2112 .

[0081] The adapter box 200 includes a first side wall 201 facing the first wall body 111, and a first connecting portion 2111 is connected to the first side wall 201 and extends in a direction away from the first side wall 201. A first hook portion 2112 is connected to an end of the first connecting portion 2111 away from the first side wall 201 and extends axially along the return air channel 100b. A first slot 211a for inserting the first wall body 111 is formed between the first hook portion 2112 and the first side wall 201, so that the adapter box 200 is connected to the first wall body 111 through the first slot 211a.

[0082] like Figure 7 As shown, the overall design of the first buckle 211 is hook-shaped (or hook-shaped), the adapter box 200 is hooked on the first wall 111 through the first buckle 211 (or the adapter box 200 is hung on the first wall 111 through the first buckle 211), the cooperation between the first connecting portion 2111 and the first wall 111 limits the movement of the adapter box 200 in the vertical direction, and the cooperation between the first hook portion 2112 and the first wall 111 limits the movement of the adapter box 200 in the horizontal direction.

[0083] Specifically, when snapping the adapter box 200 to the first wall body 111, first lift the adapter box 200 to a certain height so that the first buckle 211 moves to make the first slot 211a located above the first wall body 111, and then lower the adapter box 200 so that the first wall body 111 is inserted into the first slot 211a. In this way, the adapter box 200 can be snapped to the first wall body 111, and the installation is convenient and quick.

[0084] Moreover, the first wall body 111 is inserted into the first card slot 211a, that is, the first clip 211 is clamped at the free end of the first wall body 111. Therefore, when the adapter box 200 needs to be disassembled, the adapter box 200 is driven to move upward by applying an upward lifting force, so that the first wall body 111 is disengaged from the first card slot 211a, and the clamping fit between the adapter box 200 and the first wall body 111 can be released. There is no need to use brute force, which makes it more convenient for the user to disassemble the adapter box 200 in the return air duct 100b, making disassembly more convenient and quick.

[0085] In one embodiment, the housing cover 100 further includes a second wall, and an extension direction of the second wall is arranged to intersect with an extension direction of the first wall.

[0086] The extension direction of the second wall crosses the extension direction of the first wall, so the second wall is not parallel to the first wall. For example, the second wall and the first wall can be bent and connected, and an angle is formed between the second wall and the first wall.

[0087] Please refer to Figure 4 and Figure 7 In one embodiment, the air guide frame 110 includes a first wall 111 and a second wall 112. The first wall 111 extends axially along the return air channel 100b, and the second wall 112 is bent and connected to an end of the first wall 111 close to the return air port 100a. In this embodiment, the bending angles of the first wall 111 and the second wall 112 are not limited. Figure 4 As shown, the bending angle of the first wall 111 and the second wall 112 can be 90°, so that the first wall 111 and the second wall 112 are vertically connected to form an "L" shape.

[0088] The adapter box 200 may further include a second buckle, and the second buckle is buckled with the second wall.

[0089] That is to say, in this embodiment, based on the first buckle connecting the adapter box to the first wall, a second buckle is also provided to connect it to the second wall. By providing two buckles, the adapter box can be connected to different walls respectively, which can improve the firmness of the connection between the adapter box 200 and the shell cover 100.

[0090] The first buckle and the second buckle may be designed to adopt the same buckling structure or buckling method, or may be designed to adopt different buckling structures or buckling methods.

[0091] In one embodiment, please combine Figure 4 , Figure 6 And refer to Figure 8 , Figure 8 for Figure 4 The second buckle 212 includes a second hook portion 2122, which is located at one side of the second wall 112 and is provided with a second slot 212a. A post 1121 is convexly provided on the surface of the second wall 112, and the post 1121 is inserted into the second slot 212a to enable the second hook portion 2122 to be engaged with the second wall 112.

[0092] Then, by providing a clamping column 1121 on the second wall 112 and a second clamping groove 212a on the second hook portion 2122, and by inserting the clamping column 1121 into the second clamping groove 212a, the clamping column 1121 can block the second hook portion 2122. The cooperation between the clamping column 1121 and the second clamping groove 212a limits the freedom of the second hook portion 2122 to move along the surface of the second wall 112, preventing the second hook portion 2122 from moving along the second wall 112 due to slight vibration and causing the clamping effect between the two to be released, thereby enhancing the stability of the clamping between the adapter box 200 and the shell cover 100.

[0093] The second buckle 212 may be connected to the first side wall 201 of the adapter box 200 , or may be connected to the bottom wall of the adapter box 200 , which is not limited in this embodiment.

[0094] In one embodiment, the second buckle 212 is connected to the first side wall 201, so that the second hook portion 2122 can be located on one side of the second wall 112. Figure 6 and Figure 7 The second buckle 212 also includes a second connecting portion 2121, which is connected to the first side wall 201, the second connecting portion 2121 abuts against the first wall 111, and the second hook portion 2122 is connected to an end of the second connecting portion 2121 away from the first buckle 211, and extends in a direction away from the first side wall 201.

[0095] By providing the second connection portion 2121 and connecting the second hook portion 2122 to the end of the second connection portion 2121 , the second hook portion 2122 can be located on one side of the second wall 112 when the adapter box 200 is not high enough.

[0096] Moreover, the second connection portion 2121 abuts against the first wall 111. Figure 7As shown, the adapter box 200 has a larger contact area with the first wall 111 through the second connection portion 2121, which can further enhance the stability of the connection between the adapter box 200 and the shell cover 100.

[0097] Specifically, in the process of snapping the adapter box 200 and the shell cover 100, the adapter box 200 is first sent into the return air duct 100b in the vertical direction, and then the posture of the adapter box 200 is adjusted so that the adapter box 200 swings at a small angle relative to the first wall 111, so that the first buckle 211 is located above the first wall 111 and the second buckle 212 does not interfere with the first wall 111 (at this time, the second hook portion 2122 is located on one side of the first wall 111), and then the adapter box 200 is slowly lowered to insert the first wall 111 into the first slot 211a, so as to snap the first buckle 211 into the first wall 111. Then adjust the posture of the adapter box 200 again, and straighten the adapter box 200 to engage the second buckle 212 with the second wall 112. During the alignment process, the second hook portion 2122 moves to the lower side of the plane where the second wall 112 is located, and the clamping column 1121 exerts an extrusion force on the second hook portion 2122 toward the side of the second wall 112, causing the second hook portion 2122 to bend and deform. The clamping column 1121 gradually presses the second hook portion 2122 downward until the clamping column 1121 is inserted into the second slot 212a, thereby engaging the second buckle 212 with the second wall 112.

[0098] In order to facilitate the engagement of the second hook portion 2122 with the second wall 112, in one embodiment, Figure 8 As shown, a surface of the clamping column 1121 close to the first side wall 201 is designed as an inclined surface.

[0099] It can be understood that during the process of the second hook portion 2122 being engaged with the second wall 112, since the clamping column 1121 is protruding from the surface of the second wall 112, the clamping column 1121 will generate a certain resistance to the second hook portion 2122, thereby preventing the second hook portion 2122 from moving to the side of the second wall 112. In this embodiment, by setting a side of the clamping column 1121 close to the first side wall 201 as an inclined surface, the second hook portion 2122 will first contact the inclined surface of the clamping column 1121, thereby reducing the resistance of the second hook portion 2122, and the clamping column 1121 can guide the second hook portion 2122 to move downward through the inclined surface, thereby making it easier for the second hook portion 2122 to bend and deform, so that the user can insert the clamping column 1121 into the second clamping groove 212a of the second hook portion 2122 with a relatively small force, thereby making it easier to achieve the engagement of the second hook portion 2122 with the second wall 112.

[0100] Of course, in other optional implementations of the present invention, the surface of the clamping column 1121 facing the first side wall 201 may also be a curved surface.

[0101] In one embodiment, please refer to Figure 7 The second buckle 212 (second hook portion 2122) includes a first surface 212b facing the second wall 112, and the distance from the first surface 212b to the second wall 112 increases from an end of the first surface 212b close to the first side wall 201 to an end away from the first side wall 201.

[0102] That is to say, the distance from the first surface 212b to the second wall 112 increases from one end to the other end, and the first surface 212b can be a slope or a curved surface (only the slope is used as an example in the figure). Then, during the clamping process between the second hook portion 2122 and the second wall 112, since the distance from the end of the first surface 212b away from the first side wall 201 to the second wall 112 is large, the clamping column 1121 will initially contact the first surface 212b of the second hook portion 2122, the first hook portion 2112 has less resistance to the clamping column 1121, and the clamping column 1121 moves relatively along the first surface 212b (relatively speaking, it is actually stationary), which makes it easier for the second hook portion 2122 to bend and deform until the clamping column 1121 is inserted into the second slot 212a.

[0103] To further enhance the stability of the connection between the adapter box 200 and the housing cover 100, in one embodiment, please refer to Fig. 9 and Fig.10 , Fig. 9 This is a partial structural schematic diagram of the housing assembly of the utility model embodiment at a second viewing angle. Fig.10 for Fig. 9 A partial enlarged view of the middle C. Two limiting protrusions 1122 are further provided on the side of the second wall 112 away from the first wall 111 . The two limiting protrusions 1122 are relatively spaced apart, and the second hook portion 2122 of the second buckle (212) is located between the two limiting protrusions 1122 .

[0104] By providing two limiting protrusions 1122, the two limiting protrusions 1122 will block the second hook portion 2122, and the two limiting protrusions 1122 limit the freedom of the second hook portion 2122 to move left and right in the horizontal direction, that is, limit the freedom of the horizontal movement of the adapter box 200, which can prevent the adapter box 200 from moving horizontally due to vibration, and further ensure that the adapter box 200 is firmly connected to the shell cover 100. At the same time, the two limiting protrusions 1122 play a positioning role in the installation of the adapter box 200, so that the adapter box 200 can be installed in the required position of the design, so as to facilitate the wiring of the adapter box 200 and the electric control junction box 300.

[0105] Among them, the distance between the two limiting protrusions 1122 can be slightly larger than the width of the second hook portion 2122 along the horizontal direction, which can avoid the impact of manufacturing errors or assembly errors on the installation process, so that the adapter box 200 can be smoothly connected to the shell cover 100.

[0106] In another embodiment, two limiting protrusions (not shown) may also be provided on the first wall 111 of the shell cover 100 , the two limiting protrusions are relatively spaced apart, and the first buckle 211 is located between the two limiting protrusions.

[0107] Similarly, by setting two limiting protrusions, the first clip 211 is located between the two limiting protrusions. The two limiting protrusions limit the freedom of the first clip 211 to move left and right in the horizontal direction, that is, limit the freedom of horizontal movement of the adapter box 200, which can prevent the adapter box 200 from moving horizontally due to vibration, and further ensure the stability of the connection between the adapter box 200 and the shell cover 100.

[0108] Please refer to Figure 6 The adapter box 200 includes a base 210, a cover 220 and a circuit board 230. The base 210 is provided with a receiving groove 210a, the circuit board 230 is arranged in the receiving groove 210a, and the cover 220 is connected to the base 210 and covers the receiving groove 210a. The first buckle 211 and the second buckle 212 are connected to the base 210, and the base 210 is buckled with the shell cover 100 through the first buckle 211 and the second buckle 212.

[0109] The first buckle 211 and the second buckle 212 can be integrally injection-molded with the base 210 by an injection molding process.

[0110] To facilitate the electrical connection between the circuit board 230 of the adapter box 200 and the control main board in the electric control junction box 300, please continue to refer to Figure 6 The cover body 220 is also provided with a line-passing notch 220a, and the line-passing notch 220a is communicated with the receiving groove 210a.

[0111] By providing the wire-passing notch 220a, the wire harness connected to the control mainboard in the electric control junction box 300 can be directly passed through the wire-passing notch 220a to be connected to the circuit board 230 in the adapter box 200, and the wiring can be completed by directly inserting it, without removing the cover 220 from the base 210. Therefore, the adapter box 200 provided by the utility model is not only convenient to install, but also simple and convenient to wire after installation, which can improve the user experience.

[0112] Please refer to Figure 2 and Figure 5 The housing assembly 10 further includes a return air grille 500 , which is disposed at the return air port 100 a .

[0113] The return air grille 500 is used to guide air into the return air passage 100b. At the same time, a dustproof structure (such as a dustproof filter) can be integrated on the return air grille 500 to prevent dust, lint, wire scraps and other impurities in the air inside the RV from entering the air conditioner. In addition, the return air grille 500 is arranged at the return air inlet 100a, and the adapter box 200 can be sealed in the return air passage 100b to prevent passengers in the RV, such as children, from reaching their hands from the return air inlet 100a into the return air passage 100b and contacting the adapter box 200, thereby causing electric shock.

[0114] It is understandable that, in order to facilitate subsequent maintenance of the adapter box 200, the return air grille 500 can be connected to the shell cover 100 using a quick-release connection structure, for example, the return air grille 500 and the shell cover 100 can be connected by a magnetic attraction.

[0115] In order to ensure the firmness of the connection between the return air grille 500 and the housing cover 100 and to facilitate the removal of the return air grille 500, in one embodiment, the return air grille 500 is snap-connected with the housing cover 100.

[0116] In one embodiment, if Figure 2 As shown, the outer wall of the return air grille 500 is provided with a third buckle (not marked), and the side wall of the shell cover 100 forming the return air outlet 100a is provided with a third buckle (not shown in the figure), and the third buckle can be engaged with the third buckle, so that the return air grille 500 is engaged with the shell cover 100 through the third buckle and the third buckle.

[0117] It should be noted that the adapter box 200 is a high-voltage power supply to power the air conditioner. To comply with safety protection requirements, an isolation structure needs to be provided on one side of the adapter box 200 to prevent the user from getting an electric shock.

[0118] In one embodiment, please refer to Figure 5 and Figure 7 The adapter box 200 further includes a bottom wall 202, which is bent and connected to one end of the first side wall 201 near the return air port 100a. The housing assembly 10 further includes a protective net 400, which is disposed in the return air channel 100b and between the return air grille 500 and the bottom wall 202 of the adapter box 200.

[0119] like Figure 7 As shown, the protective net 400 is arranged between the return air grille 500 and the bottom wall 202 of the adapter box 200. The protective net 400 isolates the adapter box 200 and the wiring harness connected to the adapter box 200 to prevent the user from directly touching them. At the same time, the protective net 400 can prevent the junction box and the wiring harness from falling, which meets the safety protection requirements and can prevent the user from accidental electric shock.

[0120] The protective net 400 may be a metal net, a plastic net, or a wooden net made of wood material. The drawings of the embodiments of the present utility model take metal nets as examples, which cannot be regarded as a limitation of the present application.

[0121] Please refer to Fig.11 and Fig.12 , Fig.11 This is a schematic diagram of the assembly structure of the protective net of the housing assembly of the embodiment of the utility model. Fig.12 for Fig.11 The protective net 400 includes a net body 410, a frame body 420 and a plurality of connecting rods 430. The frame body 420 is arranged around the outer periphery of the net body 410 and is connected and fixed to the net body 410, and the plurality of connecting rods 430 are arranged at intervals along the length direction of the protective net 400 and are connected to the frame body 420.

[0122] It can be understood that the frame 420 and the plurality of connecting rods 430 together form the main skeleton of the protection net 400 , which can support the net body 410 and prevent the net body 410 from being deformed.

[0123] At the same time, the connecting rod 430 is also used for connection. The protective net 400 as a whole can be connected to the shell cover 100 through a plurality of connecting rods 430 .

[0124] Please refer to Fig.12 Each connecting rod 430 includes a first connecting end 431 and a second connecting end 432 opposite to each other. The first connecting end 431 extends out of the frame 420 in a direction away from the second connecting end 432, and the first connecting end 431 is in a columnar shape. The second connecting end 432 also extends in a direction away from the first connecting end 431 to be located outside the frame 420, and the second connecting end 432 is bent into a ring shape, so that the second connecting end 432 is formed with a positioning hole 432a.

[0125] like Fig.12 As shown, the air guide frame 110 also includes a third wall body 113, and the third wall body 113 is provided with a plurality of holes 113a for inserting the first connecting end 431, and the number of the holes 113a is the same as the number of the connecting rods 430, so that the first connecting end 431 of the plurality of connecting rods 430 can be inserted into the plurality of holes 113a one by one.

[0126] A plurality of positioning columns 1123 are protruding from the second wall 112, wherein the number of the positioning columns 1123 is less than the number of the connecting rods 430, and the plurality of positioning columns 1123 are used to be inserted into the positioning holes 432a of the second connecting ends 432 of some connecting rods 430. The protective net 400 can be positioned by the positioning cooperation between the positioning columns 1123 and the positioning holes 432a.

[0127] At least two threaded holes 112a are also provided on the second wall 112, and the second connecting end 432 of the remaining connecting rod 430 can be connected to the threaded hole 112a by a fastening screw passing through the positioning hole 432a, so as to connect and fix the protective net 400 to the shell cover 100. Fig.11 As shown, in the drawings of this embodiment, four connecting rods 430 are provided as an example, then two positioning columns 1123 can be provided, and two threaded holes 112a can be provided, wherein the second connecting end portions 432 of the two connecting rods 430 are respectively positioned and matched with the two positioning columns 1123 through their positioning holes 432a, and the second connecting end portions 432 of the other two connecting rods 430 are respectively connected to the two threaded holes 112a through two fastening screws.

[0128] Specifically, during the installation of the protective net 400 and the shell cover 100, the protective net 400 is first sent into the return air duct 100b in the vertical direction, and then the protective net 400 is moved in the horizontal direction so that the first connecting end 431 of each connecting rod 430 is inserted one-to-one into each socket 113a, and then the posture and position of the protective net 400 are adjusted so that a plurality of positioning columns 1123 are respectively inserted into the positioning holes 432a of the second connecting ends 432 of some of the connecting rods 430 to achieve positioning. At this time, the positioning holes 432a on the second connecting ends 432 of the remaining connecting rods 430 are aligned with the threaded holes 112a (coaxial), and finally a plurality of fastening screws are respectively passed through this part of the positioning holes 432a and threadedly connected with the threaded holes 112a to achieve the connection and fixation of the protective net 400 to the shell cover 100.

[0129] Since the protection net 400 and the shell cover 100 are fastened by screws, the protection net 400 can also be used to limit the adapter box 200, further ensuring that the adapter box 200 is firmly connected to the shell cover 100.

[0130] In one embodiment, please refer to Figure 7 The second buckle 212 (second connecting portion 2121) extends toward the bottom wall 202 until the second connecting portion 2121 exceeds the plane where the bottom wall 202 is located, so that part of the second buckle 212 (second connecting portion 2121) is located between the frame 420 and the first wall 111.

[0131] That is to say, the second connection part 2121 of the second buckle 212 is located between the frame body 420 and the first wall body 111, so that the frame body 420 and the second connection part 2121 can be adjacent to each other. Then, the frame body 420 of the protective net 400 can block the second connection part 2121, limit the freedom of horizontal movement of the second connection part 2121, and prevent the second connection part 2121 from being displaced due to severe vibration, thereby releasing the clamping effect between the second buckle 212 and the second wall body 112, thereby further enhancing the stability of the clamping between the adapter box 200 and the shell cover 100.

[0132] The utility model also provides a vehicle, the vehicle comprising an air conditioner based on any one of the above embodiments. The specific type of the vehicle is not limited, and can be a passenger car, a truck or a motor home.

[0133] Since the vehicle provided by the utility model adopts the air conditioner conceived based on the above-mentioned embodiment, the air conditioner sets the adapter box 200 in the return air duct 100b. When installing the adapter box 200, the adapter box 200 can be directly sent into the return air duct 100b through the return air port 100a for installation. Then the whole air conditioner can be pre-assembled into a nearly complete structure, and only the return air port 100a needs to be kept in an exposed state, that is, when installing the adapter box 200, there is no need to install or disassemble the shell of the air conditioner, so that the assembly of the adapter box can be facilitated under the limited space conditions of the RV. Moreover, when the adapter box 200 needs to be maintained later, the hand can also be directly inserted into the return air duct 100b to disassemble the adapter box 200 and take it out from the return air port 100a, without the need to disassemble the shell of the air conditioner on a large scale, which can facilitate maintenance. At the same time, since the adapter box 200 is arranged in the return air channel 100b, that is, on the air flow path, during the operation of the air conditioner, the air entering from the return air channel 100b can take away the heat generated by the electronic control of the adapter box 200, and the adapter box 200 can be cooled and cooled. There is no need to additionally set up a cooling fan for the adapter box 200, which can reduce costs.

[0134] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
