[0031] A mobile air conditioner is one that can be moved around and placed freely in different houses, making it more convenient to use.

[0032] To facilitate the movement of air conditioners, universal wheels are generally installed on the chassis of the indoor unit of the air conditioner. Currently, the chassis is generally equipped with four universal wheels, and each universal wheel is mounted to the chassis using four screws. In this way, the installation of the universal wheel requires multiple screws to lock, which is inefficient.

[0033] The utility model provides a chassis assembly.

[0034] See also Figures 1 to 3 In one embodiment of the present invention, the chassis assembly includes a chassis body 100 and a roller 200 , and the roller 200 is installed on the chassis body 100 through a fixing structure and a limiting structure.

[0035] Specifically, the chassis body 100 is mounted on the indoor unit of the air conditioner, and the roller 200 can be a universal wheel, a fixed wheel, or the like. The fixing structure can be a bolted connection structure, a riveted structure, or the like, and the limiting structure can be a snap-on structure, a sleeve structure, a plug-in structure, or the like. It is understandable that the assembly of a fixing structure often requires a longer time, while the assembly of a limiting structure can be completed in a shorter time. The connection between the roller 200 and the chassis body 100 often requires multiple fixing structures. The provision of a limiting structure can reduce the number of fixing structures used, thereby reducing assembly and disassembly time and improving the efficiency of chassis assembly.

[0036] The technical solution of the present invention comprises a chassis body 100 and a roller 200 provided within the chassis assembly. The roller 200 is mounted to the chassis body 100 via a fixing structure and a retaining structure. The use of the retaining structure reduces the number of fixing structures used, thereby reducing the time required for assembly and disassembly of the fixing structures, thereby reducing the time required for assembly and disassembly of the chassis assembly and improving the efficiency of assembly and disassembly of the chassis assembly.

[0037] See also Figures 1 to 3 In an embodiment of the present invention, the roller 200 includes a connected wheel body 220 and a mounting plate 210. The fixing structure includes a first fixing hole 110 provided in the chassis body 100 and a second fixing hole 211 provided in the mounting plate 210. Screws are sequentially inserted through the first fixing hole 110 and the second fixing hole 211. Thus, by sequentially inserting the screws through the first fixing hole 110 and the second fixing hole 211, the roller 200 is mounted on the chassis body 100, thereby achieving the installation and fixation of the roller 200 and ensuring the installation stability and reliability of the roller 200. However, the present design is not limited to this. In other embodiments, the fixing structure may also be a first rivet hole provided in the chassis body 100 and a second rivet hole provided in the mounting plate 210. Rivets are sequentially inserted through the first rivet hole and the second rivet hole to mount the roller 200 on the chassis body 100.

[0038] See also Figures 1 to 3 In an embodiment of the present invention, the limiting structure includes a limiting post 120 provided on the chassis body 100 and a limiting hole 212 provided on the mounting plate 210, and the limiting post 120 extends into the limiting hole 212. In this way, through the cooperation between the limiting post 120 and the limiting hole 212, the roller 200 and the chassis body 100 are limited, thereby reducing the use of the fixing structure, thereby reducing the assembly time required for the fixing structure, and improving the efficiency of the disassembly and assembly of the chassis assembly. However, the present design is not limited to this. In other embodiments, the limiting structure can also be a limiting groove provided on the chassis body 100 and a limiting protrusion provided on the mounting plate 210, and the limiting protrusion can be snapped into the limiting groove to achieve the limiting of the roller 200 and the chassis body 100.

[0039] See also Figure 3 In an embodiment of the present utility model, the limiting structure also includes a stop groove 130 provided on the chassis body 100, the first fixing hole 110 and the limiting column 120 are arranged side by side on the notch side of the stop groove 130, and the mounting plate 210 is partially inserted into the stop groove 130.

[0040] Specifically, in one embodiment, the roller 200 is positioned by the cooperation between a portion of the mounting plate 210 and the stop groove 130, and between the stop post 120 and the stop hole 212, and is secured by screws passing through the first fixing hole 110 and the second fixing hole 211. Thus, when installing the roller 200, the mounting plate 210 is first inserted into the stop groove 130, and then the stop hole 212 is aligned with the stop post 120. The mounting plate 210 is then placed over the stop post 120, with the first fixing hole 110 and the second fixing hole 211 aligned. The screw is then passed through the first fixing hole 110 and the second fixing hole 211 and tightened, thereby completing the installation of the roller 200. The provision of the stop groove 130 allows for stable installation of the chassis assembly using only one screw, minimizing the use of screws, thereby saving screw tightening time and improving the efficiency of assembly and disassembly of the chassis assembly.

[0041] In the embodiment of the present invention, guide ribs (not shown) are provided within the stop groove 130. The provision of the guide ribs provides guidance for the insertion of the mounting plate 210, allowing the mounting plate 210 to be quickly inserted into place. Along the depth direction of the stop groove 130, the guide ribs are arranged at an angle toward the chassis body 100. This ensures that once the mounting plate 210 is inserted into place, it fits snugly against the chassis body 100, facilitating the stable connection between the mounting plate 210 and the chassis body 100, and also facilitating the stable connection between the roller 200 and the chassis body 100.

[0042] See also Figure 3 In an embodiment of the present invention, reinforcing ribs 131 are provided on the outer wall of the stop groove 130. The provision of the reinforcing ribs 131 helps to improve the structural strength of the stop groove 130, thereby enhancing the connection strength and reliability between the chassis body 100 and the roller 200. In one embodiment, a plurality of reinforcing ribs 131 are provided, and the plurality of reinforcing ribs 131 are evenly spaced along the length of the stop groove 130.

[0043] See also Figure 3 In an embodiment of the present invention, a side of the limiting column 120 facing the stopping groove 130 is provided with an avoidance notch 121 .

[0044] In this embodiment, the roller 200 is installed on the chassis body 100 through the cooperation between the limiting column 120 and the limiting hole 212, the cooperation between the partial mounting plate 210 and the stop groove 130, and the screw locking. It can be understood that in order to simultaneously realize the insertion of the partial mounting plate 210 and the stop groove 130, and the socketing of the limiting column 120 and the limiting hole 212, the partial mounting plate 210 needs to have a certain movable stroke in the stop groove 130 along the thickness direction of the chassis body 100.

[0045] When removing the roller 200, first remove the screws, then lift one side of the mounting plate 210 to allow the limiting post 120 to disengage from the limiting hole 212, and then remove the mounting plate 210 from the stop groove 130. To facilitate the removal of the mounting plate 210 from the stop groove 130, an escape notch 121 is provided on the side of the limiting post 120 facing the stop groove 130. This also reduces the movable stroke, thereby improving the connection stability between the mounting plate 210 and the chassis body 100.

[0046] See also Figure 4 In an embodiment of the present invention, a second fixing hole 211 is provided at each end of one diagonal of the mounting plate 210, and a limiting hole 212 is provided at each end of the other diagonal. Thus, in this embodiment, the roller 200 and the chassis body 100 are mounted via two screws, two sets of limiting posts 120, and the limiting holes 212. This ensures both the stability of the mounting of the roller 200 and the efficiency of assembly and disassembly of the chassis assembly. Of course, in other embodiments, the two second fixing holes 211 on the mounting plate 210 are arranged side by side, and the two limiting holes 212 are also arranged side by side and opposite the two second fixing holes 211. This approach can also achieve mounting of the roller 200 and the chassis body 100.

[0047] The present utility model also proposes an air conditioner, which includes a chassis assembly. The specific structure of the chassis assembly refers to the above-mentioned embodiment. Since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0048] In an embodiment of the present invention, the air conditioner includes an indoor air conditioner unit (not shown) and an outdoor air conditioner unit (not shown); the chassis assembly is arranged on the indoor air conditioner unit; and / or, the compressor assembly of the air conditioner (not shown) is arranged on the indoor air conditioner unit; and / or, the indoor air conditioner unit and the outdoor air conditioner unit are connected by a flexible refrigerant pipe (not shown), and the flexible refrigerant pipe is pre-filled with refrigerant.

[0049] The air conditioner of the present invention can be a split-type air conditioner that is easy for users to install individually. The chassis assembly is arranged on the indoor unit of the air conditioner, thereby facilitating the movement of the indoor unit of the air conditioner and improving the convenience of use of the air conditioner.

[0050] Placing the compressor assembly in the indoor unit of the air conditioner can reduce the weight of the outdoor unit, making it easier to install. Conversely, placing the compressor assembly in the indoor unit requires a noise reduction structure to ensure comfortable use and low noise interference.

[0051] The air conditioner uses a flexible refrigerant pipe to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit. Refrigerant is injected into the refrigerant circuit before the unit leaves the factory. This allows users to install the unit themselves by simply securing the indoor and outdoor units separately, eliminating the need to assemble refrigerant pipes or add refrigerant. This simplifies installation and facilitates individual installation. However, the present design is not limited to this. In other embodiments, the air conditioner of the present invention can also be a conventional split-type air conditioner.

[0052] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
