[0037] The present utility model provides a housing assembly 10.

[0038] Please refer to Figure 1 、 Figure 2 and Figure 5 In an embodiment of the present utility model, the housing assembly 10 is applied to an air conditioner. The housing assembly 10 includes a panel 100 and an end cover 200. The panel 100 is provided with a first mounting hole 121 and a first limiting member 110. The end cover 200 is disposed at one end of the panel 100. The end cover 200 is provided with a second mounting hole 221 and a second limiting member 210. The first limiting member 110 can be in limiting cooperation with the second limiting member 210 so that the first mounting hole 121 is aligned with the second mounting hole 221.

[0039] Specifically, the end cover 200 can be a top cover or a bottom cover. The panel 100 includes one of a front panel, a rear panel, and a side panel; or, the panel 100 includes a connected front panel and side panel; or, the panel 100 includes a connected rear panel and side panel. Among them, the front panel is the main part for the air conditioner to interact with the user. Without loss of generality, the outer surface of the front panel is provided with control buttons, a display screen, or other interaction interfaces.

[0040] The second mounting hole 221 of the end cover 200 is correspondingly arranged with the first mounting hole 121 of the panel 100 for installing screws, rivets, or other fasteners to connect the panel 100 and the end cover 200. When the panel 100 and the end cover 200 are assembled, the panel 100 moves along the edge of the end cover 200. After the panel 100 is in place, the first limiting member 110 on the panel 100 and the second limiting member 210 on the end cover 200 are in mutual limiting cooperation to realize the pre-assembly between the panel 100 and the end cover 200, so that the panel 100 and the end cover 200 can remain relatively fixed, and thus the first mounting hole 121 is aligned with the second mounting hole 221, facilitating fasteners such as bolts to pass through the first mounting hole 121 and the second mounting hole 221 to firmly fix the panel 100 and the end cover 200 together. The limiting cooperation between the first limiting member 110 and the second limiting member 210 ensures the rapid and accurate alignment of the first mounting hole 121 and the second mounting hole 221, reducing the assembly time and errors of the panel 100 and the end cover 200, thereby improving the assembly efficiency. At the same time, by precisely aligning the first mounting hole 121 and the second mounting hole 221 and using fasteners for connection, the connection strength and stability between the panel 100 and the end cover 200 are enhanced.

[0041] The first limiting member 110 and the second limiting member 210 can be configured as a clamping protrusion 150 and a clamping groove, a hook and a snap ring, a hook and a groove, magnetic members for magnetic connection, etc.

[0042] The technical solution of the utility model is to set a first limit member 110 on the panel 100, and set a second limit member 210 on the end cover 200 that can cooperate with the first limit member 110. Before the first mounting hole 121 and the second mounting hole 221 are fixed by fasteners, the panel 100 and the end cover 200 can be pre-fixed so that the first mounting hole 121 and the second mounting hole 221 can be aligned, so that the fasteners can accurately and quickly connect the first mounting hole 121 and the second mounting hole 221, thereby improving the assembly efficiency of the shell assembly 10.

[0043] At the same time, the double limiting mechanism of the first limiting member 110 and the second limiting member 210, and the first mounting hole 121 and the second mounting hole 221 being locked by fasteners improves the stability of the connection between the panel 100 and the end cover 200, and can effectively reduce the risk of loosening or misalignment of the panel 100 and the end cover 200 due to vibration or external force during use, thereby ensuring the reliability and durability of the shell assembly 10 during long-term use.

[0044] In one embodiment, see Figure 3 and Figure 6 The first limiting member 110 includes a first limiting portion 111 and a second limiting portion 112 that are bent and connected, the second limiting member 210 includes a third limiting portion 211, the third limiting portion 211 forms a limiting groove 212, the first limiting portion 111 is connected to the panel 100 and is limited in the limiting groove 212, and the second limiting portion 112 is buckled on the edge of the limiting groove 212.

[0045] The first stopper 110 is disposed on the inner side wall of the panel 100 and on one side close to the end cover 200. The first stopper 111 protrudes from the inner side wall of the panel 100 and can be inserted into the stopper groove 212 of the second stopper 210. The second stopper 112 is disposed at one end of the first stopper 111 away from the panel 100 and is connected to the first stopper 111 by bending. After the first stopper 111 is inserted into the stopper groove 212, the second stopper 112 is used to buckle to the edge of the stopper groove 212 to provide additional fixation and prevent slipping.

[0046] The second stopper 210 can be arranged on the inner side wall of the end cover 200, or on the outer side wall of the end cover 200. In order to prevent the first stopper 110 and the second stopper 210 from being exposed and improve the appearance of the housing assembly 10, the second stopper 210 is arranged on the inner side wall of the end cover 200, and is arranged on a side edge of the end cover 200 close to the panel 100 corresponding to the first stopper 110. The third stopper 211 is provided with a stopper groove 212, and the stopper groove 212 can be smoothly inserted into the first stopper 111, so that the stopper groove 212 and the first stopper 111 can be matched in a stopper manner.

[0047] When the panel 100 and the end cover 200 start to be assembled, the first limiting portion 111 of the first limiting member 110 will be inserted into the limiting groove 212 of the second limiting member 210. The bottom and side walls of the limiting groove 212 limit the first limiting portion 111. At the same time, the second limiting portion 112 will be buckled to the edge of the limiting groove 212, forming a "locking" effect, thereby realizing the pre-assembly of the panel 100 and the end cover 200, enabling the first mounting hole 121 and the second mounting hole 221 to be aligned, so that the fastener can accurately and quickly connect the first mounting hole 121 and the second mounting hole 221, thus improving the assembly efficiency of the housing assembly 10.

[0048] In addition, the limiting cooperation between the first limiting portion 111 and the second limiting portion 112 and the limiting groove 212 is not a completely fixed dead buckle. When disassembly and repair are required, the disassembly is very convenient, thus facilitating the disassembly and re-assembly of the panel 100 and the end cover 200, which is beneficial to the maintenance of the housing assembly 10 and the replacement of components.

[0049] In one embodiment, please refer to Figure 4 , the third limiting portion 211 includes a limiting main board 217 and a limiting baffle 218. The limiting main board 217 forms the limiting groove 212. The limiting baffle 218 is erected on the limiting main board 217 and extends along the edge of the limiting groove 212. Among them, the first limiting portion 111 abuts against the limiting baffle 218, and the second limiting portion 112 is buckled to the limiting main board 217.

[0050] The limiting main board 217 is the main part constituting the limiting groove 212. As a flat plate, the limiting main board 217 is used to form the bottom and side walls of the limiting groove 212. A part of the first limiting portion 111 contacts the limiting main board 217, and the second limiting portion 112 is directly buckled to the limiting main board 217. The limiting baffle 218 is a plate-like structure perpendicular to the limiting main board 217 and extends along the edge of the limiting groove 212. The function of the limiting baffle 218 is to increase the contact area between the first limiting portion 111 and the bottom and side walls of the limiting groove 212, improving the limiting effect of the limiting groove 212 on the first limiting portion 111. At the same time, the limiting baffle 218 provides support for the first limiting portion 111 to ensure it is in the correct position. It can be understood that during the assembly process, the first limiting portion 111 is inserted into the limiting groove 212 and continues to move along the installation direction until the first limiting portion 111 contacts the limiting baffle 218. The limiting baffle 218 prevents the further movement of the first limiting portion 111, ensuring that the first limiting portion 111 stops in the correct position. Subsequently, the second limiting portion 112 is buckled to the limiting main board 217. By providing two flat plate structures of the limiting main board 217 and the limiting baffle 218, not only the limiting cooperation with the first limiting member 110 is realized, but also the material used for the second limiting member 210 is reduced, and its weight is lowered.

[0051] In one embodiment, please refer to Figure 4 , the third limiting portion 211 further includes a reinforcing plate 219 which is erected on the limiting main board 217 and extends along the edge of the limiting main board 217.

[0052] The reinforcing plate 219 and the limiting baffle 218 are erected on the same side surface of the limiting main board 217, and the second limiting portion 112 is buckled on the opposite side surface of the limiting main board 217. The reinforcing plate 219 extends along the edge of the limiting main board 217. One end in the extending direction of the reinforcing plate 219 is connected to the end cover 200, and the other end is connected to the limiting baffle 218. In this way, the reinforcing plate 219 will not affect the normal cooperation of the first limiting portion 111, the second limiting portion 112 and the third limiting portion 211, so the complexity of the limiting cooperation will not be increased. By providing the reinforcing plate 219, the overall rigidity of the limiting main board 217 can be significantly improved, preventing deformation or damage during long-term use or under external force, and playing a role in strengthening the third limiting portion 211.

[0053] In one embodiment, please refer to Figure 3 , the second limiting member 210 further includes a guiding portion 213 which is connected to a side wall of the limiting groove 212 away from the end cover 200 and forms a guiding groove communicating with the limiting groove 212 with the end cover 200, so that the first limiting portion 111 can move from the guiding groove to the limiting groove 212 along the extending direction of the guiding portion 213, and the guiding portion 213 inclines towards the end cover 200 in the direction close to the third limiting portion 211.

[0054] The guiding groove communicates with the limiting groove 212, and the first limiting portion 111 can easily move into the limiting groove 212 along the extending direction of the guiding portion 213. The guiding portion 213 inclines towards the end cover 200 in the direction close to the third limiting portion 211, and the guiding groove is tapered in the direction close to the third limiting portion 211. The opening at one end of the guiding groove away from the limiting groove 212 is larger, which is more convenient for the first limiting member 110 to enter the guiding groove. At the same time, the inclined design of the guiding groove provides a sufficient guiding angle to ensure that the first limiting portion 111 can smoothly transition into the limiting groove 212.

[0055] During the assembly process, the first limiting portion 111 first contacts the guiding portion 213 and starts to move along the guiding direction of the guiding groove. As the first limiting portion 111 moves along the inclined surface of the guiding portion 213, the first limiting portion 111 is gradually guided to the entrance of the limiting groove 212. Then, the first limiting portion 111 smoothly enters the limiting groove 212 and is in limiting cooperation with the limiting groove 212 of the third limiting portion 211; at the same time, the second limiting portion 112 is buckled onto the limiting main board 217 to complete the pre-assembly of the panel 100 and the end cover 200.

[0056] In one embodiment, the second limiting member 210 further includes a guiding plate. The guiding plate is connected to a side wall of the limiting groove 212 close to the end cover 200 and is connected to the end cover 200. The guiding plate is inclined away from the end cover 200 in the direction close to the third limiting portion 211. That is, the guiding portion 213 and the guiding plate are arranged in a necking shape in the direction close to the third limiting portion 211. The guiding portion 213 and the guiding plate jointly guide the first limiting portion 111, so that the first limiting portion 111 can move into the limiting groove 212 more smoothly.

[0057] In one embodiment, please refer to Figure 3 and Figure 4 , one end of the guiding portion 213 away from the limiting groove 212 is bent first in the direction close to the panel 100 and then in the direction away from the panel 100 in the direction away from the limiting groove 212.

[0058] The guiding portion 213 is bent in the direction away from the panel 100 (i.e., inwards), so that an opening for yielding is formed at the bending position of the guiding portion 213, and the first limiting portion 111 can enter the guiding groove more conveniently, so as to reduce the requirements for the assembly skills of the assemblers. The guiding portion 213 is bent in the direction towards the panel 100 (i.e., outwards), so that the guiding portion 213 protrudes outwards at the bending position, and the first limiting portion 111 is more likely to come into contact with the guiding portion 213, thereby facilitating the first limiting portion 111 to enter the limiting groove 212 along the extending direction of the guiding portion 213.

[0059] By precisely controlling the two bends of the guiding portion 213, the difficulty for the first limiting portion 111 to enter the guiding groove can be reduced, and the reliability of the guiding fit between the guiding portion 213 and the first limiting portion 111 can be improved, so that the first limiting portion 111 can enter the limiting groove 212 more smoothly, and the errors that may occur during the assembly process can be reduced, thereby shortening the overall assembly time and improving the production efficiency.

[0060] In one embodiment, please refer to Figure 4 , the second limiting member 210 further includes limiting ribs. The limiting ribs include a first limiting rib 214 and a second limiting rib 215. The first limiting rib 214 is arranged on a side wall of the limiting groove 212 away from the end cover 200, and the second limiting rib 215 is arranged on the guiding portion 213. The outer surfaces of the second limiting rib 215 are smoothly connected to the first limiting rib 214 and the guiding portion 213 respectively.

[0061] The first limiting rib 214 is arranged on a side wall of the limiting groove 212 away from the end cover 200. Its function is to reduce the distance between the two opposite groove side walls of the limiting groove 212, so that the first limiting portion 111 can be in abutting cooperation with the two opposite groove side walls, which helps to ensure that the position of the first limiting portion 111 between the two groove side walls is relatively fixed, reduce unnecessary shaking, and thus achieve a better limiting effect. In addition, the first limiting rib 214 also plays a role in increasing the structural strength of the limiting groove 212, preventing the groove side walls of the limiting groove 212 from deforming under long-term use or force.

[0062] In order to enable the first limiting portion 111 to smoothly move from the guiding portion 213 to the surface of the first limiting rib 214, the second limiting member 210 is further provided with a second limiting rib 215. The outer surfaces of the second limiting rib 215 are smoothly connected to the first limiting rib 214 and the guiding portion 213 respectively, providing a guide for the movement of the first limiting portion 111 from the guiding portion 213 to the first limiting rib 214, ensuring a smooth transition of the first limiting portion 111 during the movement from the guiding portion 213 to the first limiting rib 214, avoiding the step block formed by the end of the first limiting rib 214 and the upper surface of the guiding portion 213, and enabling the first limiting portion 111 to move along the second limiting rib 215 from the guiding portion 213 to the limiting groove 212 and abut against the upper surface of the first limiting rib 214. In addition, the second limiting rib 215 also enhances the rigidity and strength of the structure of the guiding portion 213.

[0063] In one embodiment, please refer to Figure 3 , the second limiting member 210 further includes a connecting portion 216. The connecting portion 216 is arranged at one end of the guiding portion 213 away from the third limiting portion 211 and is connected to the end cover 200.

[0064] The connecting portion 216 is arranged at one end of the guiding portion 213 away from the third limiting portion 211, ensuring that the entire length of the guiding portion 213 can effectively play its role. The connecting portion 216 firmly connects the guiding portion 213 and the end cover 200 together, enhancing the overall structural strength of the second limiting member 210 and ensuring the stability of the limiting structure when bearing external forces.

[0065] During the assembly process, the connecting portion 216 ensures that the guiding portion 213 and the end cover 200 form a stable structure. When the first limiting portion 111 moves along the guiding portion 213, the connecting portion 216 provides additional support, preventing the guiding portion 213 from shifting or deforming under the action of force, and ensuring that the first limiting portion 111 can smoothly transition from the guiding groove to the limiting groove 212 and complete the precise limiting cooperation with the third limiting portion 211.

[0066] Please refer to Figure 4, the guiding portion 213 includes a first main board 2131 and two first side boards 2132. One end of the first main board 2131 is connected to a side of the limiting groove 212 away from the end cover 200 and is smoothly connected to the corresponding limiting baffle 218. The two first side boards 2132 are respectively arranged on opposite sides of the first main board 2131 and extend along the extending direction of the first main board 2131. The first main board 2131 and the two first side boards 2132 together form a hollow structure of the guiding portion 213, which not only improves the structural strength of the guiding portion 213 but also realizes the light weight of the guiding portion 213. At the same time, the guiding portion 213 is also easy to demold and form.

[0067] Please refer to Figure 4 , the connecting portion 216 includes a second main board 2161 and two second side boards 2162. The second main board 2161 is erected at one end of the first main board 2131 away from the limiting groove 212 and is connected to the end cover 200. The two second side boards 2162 are respectively arranged on opposite sides of the second main board 2161 and extend along the extending direction of the second main board 2161. One ends of the two second side boards 2162 are respectively connected to the corresponding first side boards 2132, and the other ends are connected to the end cover 200. The second main board 2161 and the two second side boards 2162 together form a hollow structure of the connecting portion 216, which not only improves the structural strength of the connecting portion 216 but also realizes the light weight of the connecting portion 216. At the same time, the connecting portion 216 is also easy to demold and form.

[0068] In an embodiment, please refer to Figure 6 , the width of the first limiting portion 111 gradually increases in the direction close to the panel 100.

[0069] The first limiting portion 111 is narrower at one end away from the panel 100 and gradually wider at the other end close to the panel 100.

[0070] As the width of the first limiting portion 111 increases in the direction towards the panel 100, the actual contact area between the first limiting portion 111 and the panel 100 will also increase accordingly, so that the load can be dispersed, the stress can be effectively dispersed, the degree of stress concentration can be reduced, the ability of the first limiting portion 111 to resist bending and torsion can be improved, and thus the strength, rigidity and stability of the connection between the first limiting portion 111 and the panel 100 can be improved.

[0071] In an embodiment, please refer to Figure 6 , the first limiting portion 111 further includes a reinforcing rib 113, and the reinforcing rib 113 connects the first limiting portion 111 and the panel 100.

[0072] The reinforcing rib 113 connects the first limiting portion 111 and the panel 100, which can significantly improve the bonding strength between the two and reduce the deformation or fracture that may occur when bearing external loads or vibrations. It can disperse the stress at the connection between the first limiting portion 111 and the panel 100, avoid excessive stress concentration, thereby reducing material fatigue and potential failure points. Therefore, during the assembly process of the end cover 200 and the panel 100, it is ensured that the first limiting portion 111 can remain stable during the limiting process and will not break or deform due to external forces, thus improving the accuracy and reliability of the limiting fit.

[0073] In one embodiment, please refer to Figure 6 , a chamfer 114 is provided at one end of the second limiting portion 112 away from the first limiting portion 111, and the chamfer 114 is provided on the side of the second limiting portion 112 close to the panel 100.

[0074] When the second limiting portion 112 needs to be buckled to the edge of the limiting groove 212, its end with the chamfer 114 first contacts the edge of the limiting groove 212. Due to the existence of the chamfer 114, the risk of interference between the second limiting portion 112 and the bottom of the limiting groove 212 can be reduced, enabling the second limiting portion 112 to be smoothly buckled to the edge of the limiting groove 212. The setting of the chamfer 114 can also reduce the resistance during the assembly process, making the second limiting portion 112 more smooth when buckled to the edge of the limiting groove 212, reducing the assembly difficulty and improving the assembly efficiency. At the same time, during the assembly or disassembly process, the chamfer 114 can prevent the sharp edge from scratching the first limiting member 110 or the operator's finger, improving safety.

[0075] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 5 , the panel 100 includes a first plate portion 130 and two second plate portions 140.

The second plate portion 140 is provided with a first limiting member 110, the first plate portion 130 is provided with a clamping protrusion 150, and a buckle 230 adapted to be clamped with the clamping protrusion 150 is provided on the side edge of the end cover 200 opposite to the first plate portion 130.

[0076] The first plate portion 130 can be the front panel for carrying the display interface or operation interface of the air conditioner. The first plate portion 130 can also be the rear panel. The second plate portion 140 serves as the side panel and is disposed on opposite sides of the first plate portion 130 to form a frame structure. The first limiting member 110 on the second plate portion 140 is used to cooperate with the second limiting member 210 on the end cover 200 to ensure the precise alignment and fixation between the panel 100 and the end cover 200. The clamping protrusion 150 is disposed on the first plate portion 130, and the clamping buckle 230 is disposed on the side of the end cover 200 opposite to the first plate portion 130 and is adapted to the clamping protrusion 150. When the panel 100 and the end cover 200 are assembled, the clamping protrusion 150 will snap into the clamping buckle 230 to form a firm clamping connection.

[0077] During the assembly process, the second plate portion 140 moves along the edge of the end cover 200 so that the first limiting member 110 on the second plate portion 140 is in limiting cooperation with the second limiting member 210 on the end cover 200 to achieve the pre-assembly of the panel 100 and the end cover 200, enabling the first mounting hole 121 and the second mounting hole 221 to be aligned. While the first limiting member 110 and the second limiting member 210 complete the limiting cooperation, the clamping protrusion 150 on the first plate portion 130 is clamped with the clamping buckle 230 on the end cover 200 to form a more stable connection, ensuring that the pre-assembly connection between the panel 100 and the end cover 200 is more stable, and the panel 100 and the end cover 200 will not move relative to each other in the direction opposite to the installation direction, further ensuring that the first mounting hole 121 and the second mounting hole 221 always remain aligned during the locking process.

[0078] In one embodiment, please refer to Figure 3 and Figure 7 , the outer surface of the second plate portion 140 is recessed inward to form a protruding portion 120. The first mounting hole 121 is opened in the protruding portion 120, and the inner side wall of the end cover 200 is provided with a mounting post 220 corresponding to the protruding portion 120. The mounting post 220 is provided with a second mounting hole 221.

[0079] The outer surface of the second plate portion 140 is recessed inward to form a protruding portion 120, and the first mounting hole 121 is opened in the protruding portion 120. On the one hand, the area where the first mounting hole 121 is located can bear a greater load to ensure the reliable connection of the fastener; on the other hand, the fastener can be accommodated in the recessed area on the outer surface of the second plate portion 140 to prevent the fastener from protruding from the outer surface of the second plate portion 140 and scratching the skin. In addition, a screw cover can be provided in the recessed area to cover the fastener to prevent the fastener from being exposed outside, so as to improve the overall aesthetics of the housing assembly 10.

[0080] On the inner side wall of the end cap 200, mounting posts 220 are provided corresponding to the positions of the protruding portions 120. Second mounting holes 221 are formed in the mounting posts 220. The second mounting holes 221 are aligned with the first mounting holes 121 for fasteners to pass through, so as to tightly connect the panel 100 and the end cap 200 together. The settings of the protruding portions 120 and the mounting posts 220 increase the structural strength of the connection area, making the connection between the panel 100 and the end cap 200 more stable and capable of withstanding greater external loads.

[0081] In one embodiment, please refer to Figure 3 , on the inner side wall of the end cap 200, a connecting plate 240 is further provided. The mounting posts 220 are connected to the second limiting member 210 through the connecting plate 240.

[0082] As a bridge between the mounting posts 220 and the second limiting member 210, the connecting plate 240 can enhance the connection stability between the mounting posts 220 and the second limiting member 210; it can significantly enhance the structural strength inside the end cap 200; when an external force acts on the end cap 200, the force can be evenly distributed to the entire structure instead of concentrating on a certain point, thus avoiding structural damage caused by excessive local stress.

[0083] The present utility model also proposes an air conditioner, which includes a housing assembly 10. The specific structure of the housing assembly 10 refers to the above embodiments.
