The limiting member limits the distance between the chassis and the wall, thus replacing the cumbersome operation of installing multiple independent curtain brackets one by one in traditional installation. During installation, only the limiting member needs to be installed on the sidewall of the chassis, and the necessary gap between the air inlet and the curtain is ensured by keeping the limiting member close to the wall. This simplifies the installation process, improves installation efficiency, reduces labor costs, and saves the material cost of multiple independent brackets.

The two elastic arms extend into the limiting hole and are limited by the limiting part and the limiting groove.

[0008] In some embodiments of this utility model, a guide surface is provided at the end of the limiting part that is away from the elastic part. The guide surface is an inclined surface, and the distance between the side of the guide surface away from the sidewall and the elastic part is less than the distance between the side of the guide surface facing the sidewall and the elastic part.

[0017] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0018] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0019] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0020] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0021] like Figures 1 to 10As shown, according to an embodiment of the present invention, a chassis assembly is proposed, including a chassis 1 and a limiting member 2. The chassis 1 includes a main body 11 and a side wall 12 extending upward from the outer periphery of the main body 11. The main body 11 is a horizontally arranged plate-like or near-plate-like structure, and the shape of the main body 11 matches the bottom contour of the air conditioner body, such as rectangular, near-rectangular, or circular. The side wall 12 is a vertically arranged plate-like structure, surrounding the periphery of the main body 11 and extending vertically upward from the edge of the main body 11.

[0022] The limiting member 2 is connected to the side wall portion 12 by means of snap-fit, screw fixing, welding, or integral molding. The limiting member 2 is located on the side of the side wall portion 12 facing the wall. The opposite sides of the limiting member 2 have a connecting part 210 and a supporting part 211, respectively. The connecting part 210 is connected to the side of the side wall portion 12 facing the wall, and the supporting part 211 is located on the side of the limiting member 2 away from the chassis 1 and is used to abut against the wall. When the chassis 1 is installed close to the wall, the limiting member 2 is located in the gap between the side wall portion 12 and the wall. The connecting part 210 securely connects the limiting member 2 to the side wall portion 12 of the chassis 1, and the supporting part 211 directly contacts the wall to form a rigid support. The limiting member 2 restricts the movement of the chassis 1 towards the wall, thereby ensuring that the chassis 1 and the wall always maintain a certain distance, such as 10-15cm, to prevent the curtains from covering the rear air intake of the air conditioner during opening, closing, or natural descent, and to ensure unobstructed air intake.

[0023] The chassis assembly of this utility model has an upwardly extending side wall portion 12 on the outer periphery of the chassis 1, and a limiting member 2 is connected between the side wall portion 12 and the wall. The limiting member 2 limits the distance between the chassis 1 and the wall, thereby replacing the cumbersome operation of installing multiple independent curtain brackets one by one in the traditional installation. During installation, the limiting member 2 only needs to be installed on the side wall portion 12 of the chassis 1, and the necessary gap between the air inlet and the curtain can be ensured by the limiting member 2 being close to the wall. This simplifies the installation process, improves installation efficiency, reduces labor costs, and saves the material cost of multiple independent brackets.

[0024] In some embodiments of this utility model, the connecting part 210 is provided with a guide connector 22, and the side wall part 12 is provided with a limiting hole 121, and the guide connector 22 is connected to the limiting hole 121.

[0025] like Figures 1 to 4As shown, the limiting member 2 includes a box body 21, which is a rectangular box made of plastic. A guide connector 22 is provided on one outer side of the box body 21. The box body 21 can be detachably installed on the outer side of the side wall portion 12, i.e., the side close to the wall, through the guide connector 22. The opposite sides of the box body 21 have a connecting part 210 and a supporting part 211, respectively. When the chassis 1 is installed close to the wall, the connecting part 210 securely connects the limiting member 2 to the side wall portion 12, and the supporting part 211 directly contacts the wall to form a rigid support. A limiting hole 121 corresponding to the guide connector 22 is provided on the side wall portion 12. The limiting hole 121 is a through hole that penetrates the thickness of the side wall portion 12.

[0026] The guide connector 22 can switch between two states: locked and unlocked. By switching the engagement state of the guide connector 22 with the upper limit hole 121 of the side wall portion 12, a reversible connection between the limit member 2 and the side wall portion 12 is achieved. When it is necessary to fix the distance between the chassis 1 and the wall, the installer will place the housing 21 of the limit member 2 against the outside of the side wall portion 12. The end of the guide connector 22 away from the housing 21 passes through the upper limit hole 121 and achieves a stable engagement with the upper limit hole 121. The housing 21 abuts against the wall surface and forcibly restricts the movement of the chassis 1 towards the wall, ensuring that the chassis 1 and the wall always maintain a preset safe distance. When it is necessary to disassemble the box 21, apply a pulling force opposite to the extension direction of the guide connector 22 to drive the guide connector 22 to move in the opposite direction along its movement trajectory. The end of the guide connector 22 completely exits the limiting hole 121. In the unlocked state, the mechanical constraint between the limiting member 2 and the side wall 12 is released, and the box 21 can be removed from the side wall 12, thereby releasing the distance lock between the chassis 1 and the wall.

[0027] In some embodiments of this utility model, the guide connector 22 includes an elastic part 221 and a limiting part 222. The elastic part 221 includes at least two elastic arms 2211 arranged at intervals on the connecting part 210. Each of the two elastic arms 2211 is provided with a limiting part 222. The periphery of the limiting hole 121 is provided with a limiting groove 122 that cooperates with the limiting part 222. When connecting, the two elastic arms 2211 extend into the limiting hole 121 and are limited by the limiting part 222 and the limiting groove 122. When disassembling, the two elastic arms 2211 undergo elastic deformation under the action of external force, causing the limiting part 222 to disengage from the limiting groove 122 and come out of the limiting hole 121.

[0028] like Figures 1 to 6As shown, two elastic arms 2211 are spaced apart along a first direction, which is the length direction of the box body 21. Each elastic arm 2211 can be elastically bent, deforming inwards or outwards under external force, and automatically returning to its original shape after the external force disappears. The limiting part 222 is a limiting post 2221. One limiting post 2221 is provided on the surface of each elastic arm 2211. The two limiting posts 2221 are located on opposite sides of the two elastic arms 2211. The limiting post 2221 is a cylindrical, prismatic, or irregularly shaped columnar protrusion. One end of the limiting post 2221 is fixedly connected to the elastic arm 2211, and the other end extends away from the elastic arm 2211. Two limiting grooves 122 are provided around the limiting hole 121 to mate with the limiting post 2221. At least a portion of the limiting post 2221 is embedded in the limiting groove 122.

[0029] During the connection process, when the guide connector 22 approaches the limiting hole 121, the end of the limiting post 2221 first contacts the edge of the hole wall of the limiting hole 121, and continues to apply force to push the guide connector 22. The interference between the limiting post 2221 and the hole wall will compress the two elastic arms 2211 to undergo elastic bending deformation inward. At this time, the two elastic arms 2211 retract inward as a whole. As the elastic arms 2211 continue to deform inward, the limiting posts 2221 on both sides pass through the limiting hole 121. When the guide connector 22 is fully inserted into the limiting hole 121, the elastic arms 2221... As 211 gradually detaches from the pressure of the wall of the limiting hole 121, the elastic restoring force inside drives the elastic arm 2211 to reset outward. At this time, the limiting posts 2221 on both sides of the elastic arm 2211 are inserted into the limiting groove 122. The outer wall of the limiting post 2221 is tightly fitted with the groove wall of the limiting groove 122, thereby fixing the limiting post 2221 in the limiting groove 122. At this time, the two elastic arms 2211 are locked in the limiting hole 121 through the cooperation of their respective limiting posts 2221 and the limiting groove 122, and the box body 21 is firmly fixed on the side wall 12.

[0030] When disassembly is required, the installer pinches the ends of the two elastic arms 2211 and squeezes them inward, causing the two elastic arms 2211 to bend and deform inward again. The deformation of the two elastic arms 2211 drives their respective limiting posts 2221 to move inward synchronously. The two limiting posts 2221 will move towards the middle synchronously, making it easier to disengage from the limiting groove 122. After the limiting posts 2221 are completely disengaged from the limiting groove 122, if force is continued to be applied, such as pulling the box 21 outward or pushing the guide connector 22 in the opposite direction, the entire guide connector 22 can be moved outward along the central axis of the limiting hole 121, and finally completely disengaged from the limiting hole 121.

[0031] like Figure 6As shown, in some embodiments of this utility model, a guide surface 2222 is provided at the end of the limiting part 222 that is away from the elastic part 221. The guide surface 2222 is an inclined surface, and the distance between the side of the guide surface 2222 away from the sidewall part 12 and the elastic part 221 is less than the distance between the side of the guide surface 2222 facing the sidewall part 12 and the elastic part 221. By providing a guide surface 2222 at the free end of the limiting part 222, the limiting post 2221 can slide more smoothly into the limiting hole 121 and accurately embed into the limiting groove 122, reducing insertion resistance and simplifying alignment operations; during disassembly, the friction between the limiting post 2221 and the hole wall of the limiting hole 121 is reduced, assisting the limiting post 2221 to quickly detach from the limiting groove 122 and slide out of the limiting hole 121, avoiding jamming, thereby improving the smoothness and ease of operation of the guide connector 22 during installation and disassembly, and reducing the difficulty of installation and maintenance.

[0032] like Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the side wall portion 12 extends with a flange portion 123 in the direction toward the center of the chassis 1, and the limiting hole 121 penetrates the flange portion 123. The flange portion 123 is a plate-like structure protruding from the inner edge of the side wall portion 12 toward the inner cavity, which is used to provide an installation carrier for the limiting hole 121 and enhance the local structural strength. The limiting hole 121 is opened on the flange portion 123, which provides a more stable operating space for the cooperation between the limiting post 2221 and the limiting groove 122, and at the same time improves the reliability of the connection between the limiting member 2 and the side wall portion 12.

[0033] In some embodiments of this utility model, at least one reinforcing rib 124 is provided on the outer periphery of the flange portion 123, and the at least one reinforcing rib 124 is respectively connected to the flange portion 123 and the side wall portion 12.

[0034] like Figure 2 and Figure 4 As shown, in this embodiment, there are multiple reinforcing ribs 124, which are spaced apart circumferentially along the flange 123. Each reinforcing rib 124 is a triangular unit structure, with its two sides integrally injection molded with the outer peripheral surface of the flange 123 and the inner surface of the side wall 12. The multiple reinforcing ribs 124 form a multi-point rigid support structure, which not only disperses the stress concentration around the limiting hole 121 and prevents the flange 123 from deforming and cracking due to the insertion and removal of the limiting post 2221 or the force of the spacing lock, but also enhances the connection between the flange 123 and the side wall 12, preventing the flange 123 from falling off or loosening. This improves the overall strength and durability of the limiting hole 121 area and ensures the stability and reliability of the connection between the limiting member 2 and the chassis 1.

[0035] In some embodiments of this utility model, there are multiple guide connectors 22 and multiple limiting holes 121. Multiple guide connectors 22 are spaced apart along the length direction of the connecting portion 210, and multiple limiting holes 121 are spaced apart along the length direction of the side wall portion 12 and correspond one-to-one with the multiple guide connectors 22. The length direction of the connecting portion 210 is consistent with the length direction of the side wall portion 12. Multiple guide connectors 22 and limiting holes 121 are spaced apart along the length of the box body 21 and the side wall 12 to form a multi-point evenly distributed limiting and locking structure. This disperses the force between the chassis 1 and the wall to multiple locking points, avoiding deformation or loosening caused by local stress concentration, and improving the stability and vibration resistance of the connection. In addition, the arrangement of guide connectors 22 and limiting holes 121 forms a regular arrangement of positioning points. During installation, it is only necessary to first align one guide connector 22 with the limiting hole 121 and complete the snap-fit. The remaining guide connectors 22 can be quickly and manually pushed into the corresponding limiting holes 121 based on the already positioned reference point, eliminating the tedious step of precise alignment one by one and improving installation efficiency.

[0036] like Figure 9 and Figure 10 As shown, in another example, the housing 21 can also be connected to the side wall 12 by bolts or other means. This is achieved by fasteners 3, such as bolts or screws, passing through the mounting holes on the housing 21 and corresponding screw holes or pre-embedded nuts on the side wall 12, and tightening them securely. The housing 21 is provided with a clearance groove 24, and the mounting holes are located within the clearance groove 24. The depth of the clearance groove 24 provides space for the bolt head or nut to sink, shortening the effective working distance of the bolt from the mounting hole on the housing 21 to the screw hole on the side wall 12. This allows for a stable connection between the housing 21 and the side wall 12 without the need for excessively long bolts. The rigid connection between the housing 21 and the side wall 12 is achieved directly through mechanical tightening force, resulting in a more stable structure suitable for installation scenarios requiring higher connection strength, such as high-power air conditioners or environments with frequent vibrations, meeting the installation needs of different working conditions.

[0037] In some embodiments of this utility model, the limiting member 2 is provided with a positioning part 23, and the side wall part 12 is provided with a positioning mating part, and the positioning part 23 is positioned and connected with the positioning mating part. By setting the positioning part 23 and the positioning mating part, the correct installation position of the limiting member 2 can be quickly determined during installation, so that the guide connecting member 22 is precisely aligned with the limiting hole 121, further improving the installation efficiency.

[0038] In some embodiments of this utility model, the positioning part 23 includes one of a positioning rib 231 and a positioning groove 125, and the positioning mating part includes the other of a positioning rib 231 and a positioning groove 125, wherein the positioning rib 231 mates with the positioning groove 125. For example... Figures 6 to 8As shown, in this embodiment, the box body 21 is provided with multiple positioning ribs 231, which are spaced apart along the length of the box body 21 and integrally injection molded with the box body 21. The outer surface of the side wall portion 12 is provided with positioning grooves 125 corresponding to the positioning ribs 231. The two are guided by complementary shapes, such as rectangular protrusions and rectangular grooves, and trapezoidal bevels, to achieve sliding engagement, thereby limiting the lateral displacement of the box body 21 and the side wall portion 12. Through the precise alignment and engagement of the positioning ribs 231 and the positioning grooves 125, the relative position of the box body 21 and the side wall portion 12 is quickly fixed, ensuring that the guide connector 22 and the limiting hole 121 are automatically aligned, improving installation efficiency; at the same time, it limits the horizontal displacement and rotation of the box body 21, enhancing the stability and reliability of the connection.

[0039] The second aspect of this utility model provides an air conditioner, including a cabinet and a chassis assembly as described above, the chassis assembly being disposed at the bottom of the cabinet. During installation, the positioning ribs 231 of the housing 21 and the positioning grooves 125 of the side wall portion 12 are quickly pre-positioned, ensuring precise alignment of the guide connector 22 with the limiting hole 121. Then, the limiting post 2221 of the elastic arm 2211 is embedded into the limiting groove 122 around the limiting hole 121 to achieve rapid connection. Simply pushing the housing 21 to complete the pre-positioning and elastic engagement allows for quick locking, maintaining a stable and safe distance between the chassis assembly and the cabinet and the wall, improving assembly efficiency while reducing material and labor costs.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
