[0038] like Figures 1 to 8 As shown, the present invention provides a housing assembly, including a panel 10 and a maintenance plate 11 disposed on the panel 10. The panel 10 has a maintenance opening 101, and the maintenance plate 11 is movably disposed in the maintenance opening 101. The maintenance plate 11 can rotate relative to the panel 10 to open or close the maintenance opening 101.

[0039] The panel 10 is provided with a first mounting hole 12 and a mounting groove 13 communicating with the first mounting hole 12;

[0040] The repair plate 11 is provided with a first connecting part 14, which has a first end 141 and a second end 142. The first end 141 passes through the first mounting hole 12 and extends into the mounting groove 13 and can rotate within the mounting groove 13. The second end 142 is connected to the repair plate 11 and is located outside the first mounting hole 12.

[0041] This housing assembly is used in an air conditioner, which includes an air conditioner body. Functional modules are located on the inner side of the air conditioner body or service panel 11. By rotating the service panel 11 to open the service port 101, the functional modules can be inspected and repaired, making it convenient to use. In some scenarios, the panel 10 is installed on the ceiling, requiring workers to operate the service panel 11 at a height. The rotating service panel 11 provided in this application facilitates this operation; workers only need to rotate the service panel 11 to a certain angle, eliminating the need to remove the entire service panel 11 and increase the difficulty of working at height, thus providing convenience for workers during maintenance. Figure 1 and Figure 4 As shown, the maintenance plate 11 has, for example, a connecting end 111 and a free end 112 opposite to the connecting end 111. The connecting end 111 is rotatably connected to the panel 10, and the free end 112 can be movably installed on the panel 10 by means of snap-fit, magnetic attraction, etc. When it is necessary to operate the maintenance plate 11, the free end 112 is disengaged from the panel 10 and then the maintenance plate 11 is rotated.

[0042] In some embodiments, the inner side of the maintenance plate 11 is provided with parts or modules that need maintenance. When the maintenance plate 11 is rotated to open the maintenance port 101, the inner side of the maintenance plate 11 is exposed, and the height of the maintenance plate 11 is lower than when it is not opened. This facilitates the maintenance of the structure on the maintenance plate 11 by the staff, reduces the difficulty of the operation, and improves work efficiency. The maintenance plate 11 is rotatably mounted on the panel 10 through the first connecting part 14. When installing the maintenance plate 11, the first end 141 of the first connecting part 14 can pass through the first mounting hole 12 and extend into the mounting groove 13. An interference fit can be used between the first connecting part 14 and the first mounting hole 12 so that after the first end 141 of the first connecting part 14 extends into the mounting groove 13 through the first mounting hole 12 in the natural state, the first end 141 of the first connecting part 14 will not come out of the mounting groove 13, thus ensuring the reliability of the installation of the maintenance plate 11. It is understandable that, in order to improve the installation effect, a limiting structure can be set between the first connecting part 14 and the mounting groove 13 to further prevent the first connecting part 14 from coming out of the mounting groove 13, and ensure that the connecting end 111 of the maintenance plate 11 is always connected to the panel 10 during the rotation of the maintenance plate 11 to ensure that the maintenance plate 11 will not fall off and avoid safety problems.

[0043] In a preferred embodiment of the present invention, a limiting part 15 is provided in the mounting groove 13, and the end of the first end 141 is at least partially located on the lower side of the limiting part 15; the limiting part 15 is configured such that when the maintenance plate 11 rotates, the end of the first end 141 at least partially engages with the limiting part 15 to stop.

[0044] By providing a limiting part 15, on the one hand, the limiting part 15 can prevent the first connecting part 14 from dislodging from the mounting groove 13, providing installation protection for the first connecting part 14; on the other hand, during the rotation of the repair plate 11, at least part of the end of the first end 141 engages with the stop of the limiting part 15, increasing friction through their contact, which limits the rotation speed of the repair plate 11, preventing it from rotating too fast and potentially hitting personnel, thus improving safety. Furthermore, it can limit the rotation angle of the repair plate 11, avoiding excessive rotation and increasing the probability of the first connecting part 14 dislodging from the mounting groove 13, ensuring installation reliability. Figure 1 and Figure 2 As shown, when the maintenance plate 11 is in the closed state, at least part of the end of the first end 141 is located on the lower side of the limiting part 15 and the two do not contact each other. As the maintenance plate 11 is rotated open, at least part of the position of the end of the first end 141 changes and can contact the lower surface of the limiting part 15 to achieve a stop engagement, thereby limiting the rotation speed and angle.

[0045] In some embodiments, the maintenance plate 11 is provided with the first connecting portion 14 at both ends along its length, and the panel 10 is provided with a plurality of first mounting holes 12 and mounting grooves 13, such as... Figure 4 and Figure 5 As shown, an example is provided where the repair plate 11 has two first connecting parts 14, which can ensure the installation firmness of the repair plate 11 and ensure that the repair plate 11 rotates smoothly and avoids jamming.

[0046] Furthermore, such as Figure 2 or Figure 6 As shown, the mounting groove 13 has a limiting part 15 on one side of the groove wall near the edge of the panel 10, that is, each mounting groove 13 has at least one limiting part 15 to simplify the structure and reduce structural complexity. When the mounting groove 13 has only one limiting part 15, the limiting part 15 is closer to the end of the repair plate 11 along the length direction, which can ensure that the two ends of the repair plate 11 along the length direction are subjected to the action of the limiting part 15, so that the repair plate 11 rotates smoothly as a whole, avoiding the situation where the two ends of the repair plate 11 are unbalanced and one side is high and the other side is low, which would affect the rotation effect of the repair plate 11.

[0047] Furthermore, the first end 141 is provided with two connecting arms 143 spaced apart, and the ends of the connecting arms 143 are provided with outwardly extending extension shafts 144. Figure 2 In the example, only one of the two extension shafts 144 of each first connecting part 14 engages with the limiting part 15. To ensure that the corresponding extension shaft 144 is always located below the limiting part 15, the two partially overlap in the vertical direction, that is, the distal end of the extension shaft 144 is located outside the inner side of the limiting part 15 (i.e., the side away from the groove wall), ensuring that the extension shaft 144 can contact the limiting part 15 when it floats upward without dislodging from the inner side of the limiting part 15 and exiting the mounting groove 13.

[0048] Based on the above embodiment, the limiting part 15 extends obliquely upward in the direction toward the first mounting hole 12. As a result, during the rotational opening of the maintenance plate 11, the relevant structure of the first end 141 can gradually contact the limiting part 15 upward and move along the extending direction of the limiting part 15, which can avoid rotational interference and prevent the maintenance plate 11 from only being able to rotate open to a small angle, thus affecting maintenance.

[0049] For example, such as Figure 6As shown, the limiting part 15 includes a first segment 152, a second segment 153, and a third segment 154 connected sequentially from bottom to top. The first segment 152 can extend horizontally or inclined upwards, and the first segment 152 is connected to the groove wall. The second segment 153 and the third segment 154 both extend inclined upwards. Preferably, along the direction from the first segment 152 to the third segment 154, the inclination angle of each segment gradually increases, which is conducive to the smooth rotation of the maintenance plate 11 and avoids excessively fast rotation that could easily injure people.

[0050] Furthermore, the end of the limiting part 15 away from the first mounting hole 12 is connected to the groove wall of the mounting groove 13, and a gap 151 is provided between the end of the limiting part 15 near the first mounting hole 12 and the groove wall.

[0051] By providing the gap 151, the limiting part 15 can undergo a certain degree of bending deformation. This prevents the limiting part 15 from generating excessive resistance to the extending shaft 144 during contact with the limiting part 15, thus affecting the rotation of the first connecting part 14 and consequently the rotation of the repair plate 11, ensuring smooth rotation of the repair plate 11. The limiting part 15 of this application can undergo a certain degree of deformation, improving the rotation effect of the first connecting part 14 while ensuring the limiting effect on the first end 141. In the three-section structure of the limiting part 15, the gap 151 is provided at the corresponding positions of the third section 154 and at least part of the second section 153 to ensure the rotation effect of the first connecting part 14.

[0052] In some embodiments, such as Figure 4 As shown, the first connecting portion 14 extends in an arc shape, and the second end 142 is connected to the maintenance plate 11. The first end 141 includes two arc-shaped, spaced-apart connecting arms 143, and the ends of the connecting arms 143 are provided with outwardly extending extension shafts 144. To facilitate the installation of the maintenance plate 11, the first mounting hole 12 has clearance openings 121 on both sides along the width direction of the first connecting portion 14 to avoid the extension shafts 144. The clearance openings 121 communicate with the first mounting hole 12. Figure 7 and Figure 8 As shown, the first mounting hole 12 is approximately rectangular, and the clearance opening 121 is formed by the corresponding side wall recess of the first mounting hole 12, providing conditions for the extension shaft 144 to pass through.

[0053] Preferably, the first connecting part 14 has a certain elasticity, and the width of the line connecting the two extension shafts 144 is slightly larger than the width of the line connecting the two clearance openings 121. During installation, the first connecting part 14 can be deformed by squeezing it slightly so that the two extension shafts 144 can pass through the two clearance openings 121 respectively. In this way, after the first end 141 passes through the first mounting hole 12, it can be stably held in the mounting groove 13, ensuring the reliability of installation.

[0054] Furthermore, the sidewall of the clearance opening 121 transitions with the sidewall of the first mounting hole 12 via a fillet 122, and the outer end of the extension shaft 144 is provided with a slope 145 that avoids the fillet 122. Figure 4 and Figure 8 As shown, when the extension shaft 144 passes through the clearance opening 121, the inclined surface 145 helps to avoid the fillet 122, which can reduce friction between parts, prevent wear of parts, and improve assembly efficiency.

[0055] Based on the above embodiments, as a preferred embodiment of the present invention, the repair plate 11 is provided with a second connecting part 16, one end of the second connecting part 16 is connected to the repair plate 11, and the other end of the second connecting part 16 protrudes outward with a boss 161; the panel 10 is provided with a second mounting hole 17, and the boss 161 passes through the second mounting hole 17 and overlaps the inner side surface of the panel 10.

[0056] like Figure 1 , Figures 3 to 5 As shown, the maintenance plate 11 has two first connecting portions 14 and one second connecting portion 16 spaced apart along its length. The second connecting portion 16 is located in the middle, and the two first connecting portions 14 are located at both ends. With the limiting portions 15 provided in the two mounting grooves 13 at both ends of the panel 10, the first connecting portions 14 at both ends are restricted by the limiting portions 15 during the rotation of the maintenance plate 11, ensuring that the maintenance plate 11 rotates evenly and smoothly along its length. Based on this, the structure of the second connecting portion 16 and the second mounting hole 17 located in the middle can be relatively simplified without affecting the rotation effect of the maintenance plate 11. The boss 161 overlaps with the inner side of the panel 10, and the contact area between the two is large, which can enhance the support effect of the panel 10 on the maintenance plate 11 when it is closed, improve the installation firmness, and the boss 161 rotates around the inner side of the panel 10 during the rotation of the maintenance plate 11, which can prevent rotation jamming.

[0057] To ensure that the connecting end 111 of the maintenance plate 11 remains connected to the panel 10 during rotation, preventing the maintenance plate 11 from falling and injuring people, the second connecting part 16 has a certain degree of elasticity. During installation, the second connecting part 16 can be squeezed slightly to make the boss 161 pass through the second mounting hole 17. The second connecting part 16 and the second mounting hole 17 are interference-fitted to ensure that the second connecting part 16 does not come out of the second mounting hole 17, thus ensuring the installation reliability of the maintenance plate 11.

[0058] It is understood that the number and distribution of the first connecting part 14 and the second connecting part 16 are not limited to the above-described manner. They can be adjusted according to the length of the repair plate 11 and the desired rotation effect, so as to simplify the structure of the repair plate 11 as much as possible while ensuring that the repair plate 11 can rotate stably and smoothly.

[0059] The housing assembly provided by this utility model, by rotatably connecting the maintenance plate 11 to the panel 10, allows for easy maintenance by simply rotating the maintenance plate 11 to open the maintenance port 101. This simple and efficient operation eliminates the need for workers to remove the entire maintenance plate 11, thus reducing their workload and effort. After maintenance, the maintenance plate 11 is rotated back to close the maintenance port 101. The entire maintenance process is quick, significantly improving work efficiency and saving labor costs. The maintenance plate 11 is installed and rotated via its first connecting part 14, resulting in a simple structure, reliable operation, and improved performance of the air conditioner.

[0060] This utility model also provides an air conditioner, including the housing assembly as described above. In some scenarios, the housing assembly is installed on the ceiling, and the operator needs to operate the maintenance panel 11 at a height. The rotating maintenance panel 11 provided in this application provides convenience for the operator. The operator only needs to rotate the maintenance panel 11 to a certain angle, without having to remove the entire maintenance panel 11, which would increase the difficulty of working at height, thus providing convenience for the operator's maintenance.

[0061] The air conditioner provided by this utility model has a maintenance plate 11 rotatably connected to the panel 10. When maintenance is needed, simply rotate the maintenance plate 11 to open the maintenance port 101. The operation is simple and efficient. The operator does not need to remove the entire maintenance plate 11 and therefore does not have to bear the weight of the maintenance plate 11, making the operation relatively easy and labor-saving. After the maintenance is completed, simply rotate the maintenance plate 11 to close the maintenance port 101. The entire maintenance process is short, which can greatly improve work efficiency and save labor costs. The maintenance plate 11 is installed on the panel 10 through the first connecting part 14 and can rotate. The structure is simple, the use is reliable, and it can improve the performance of the air conditioner.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
