[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] The following is combined with Figures 1-6 This utility model describes a connection structure between a cover and a decorative panel, used to connect a cover 100 and a decorative panel 200. The cover 100 is provided with a recessed structure, and the recessed structure is adapted to the decorative panel 200. The connection structure between the cover and the decorative panel includes an elastic support protrusion 1, multiple claws 2 and multiple slots 3.

[0040] The elastic support protrusion 1 is provided on the sunken structure, and the elastic support protrusion 1 is located on both sides of the sunken structure. The elastic support protrusion 1 is used to overlap the decorative panel 200. The claw 2 and the slot 3 are provided correspondingly, and one of the claw 2 and the slot 3 is provided on the cover 100, and the other is provided on the slot 3.

[0041] The connection structure between the cover and the decorative panel provided by this utility model achieves the snap-fit ​​fixation of the decorative panel 200 and the cover 100 through the connection of multiple claws 2 and multiple slots 3. The decorative panel 200 overlaps the elastic support protrusion 1 set on the sunken structure. Even if the air conditioner vibrates during operation, it can be absorbed by the elastic deformation of the elastic support protrusion 1, avoiding stress concentration caused by rigid connection and preventing the decorative panel 200 from loosening with the cover 100. The elastic support protrusion 1 applies a uniform upward support force to the decorative panel 200, which is balanced with the clamping force of the claws 2, ensuring that the gap width deviation between the cover 100 and the decorative panel 200 is controlled within a certain range, so that the gap between the decorative panel 200 and the cover 100 is uniform.

[0042] Furthermore, through the adaptation design of the sunken structure and the trim panel 200, combined with the overlapping of the elastic support protrusion 1, precise control of the flatness of the cover 100 and the trim panel 200 is achieved. The elastic support protrusion 1 provides uniform support force, preventing local deformation of the trim panel 200 due to gravity or vibration, ensuring a seamless connection between the two surfaces, eliminating step differences, and improving the product's appearance quality. Here, step difference refers to the height difference or step-like drop between two adjacent components after assembly in the field of industrial design and manufacturing.

[0043] It can be understood that there are multiple claws 2 and multiple slots 3. When the claws 2 are set on the cover 100, the slots 3 are correspondingly set on the trim panel 200. Alternatively, when the claws 2 are set on the trim panel 100, the slots 3 are correspondingly set on the cover 100. Or, both the trim panel 100 and the cover 200 are provided with claws 2 and slots 3, with the claws 2 on the trim panel 100 corresponding to the slots 3 on the cover 200, and the slots 3 on the trim panel 100 corresponding to the claws 2 on the cover 200. As long as the engagement of the claws 2 and slots 3 allows for a detachable connection between the trim panel 100 and the cover 200, it is acceptable.

[0044] like Figures 1-3As shown, in a feasible embodiment of this utility model, the recessed structure is rectangular, including a first long side and a second long side arranged opposite to each other. One of the first and second long sides has an anti-loosening groove 4 extending along its extension direction, and an anti-loosening block 5 is disposed within the anti-loosening groove 4. A protruding strip 6 is provided on the decorative panel 200 facing the recessed structure, and the protruding strip 6 is engaged within the anti-loosening groove 4 and secured to the anti-loosening block 5. The combination of the anti-loosening groove 4 and the anti-loosening block 5 forms a double constraint, both laterally and longitudinally. The protruding strip 6 engages with the anti-loosening groove 4, restricting the horizontal displacement of the decorative panel 200 (e.g., the X direction), while the anti-loosening block 5 secures to the protruding strip 6, preventing the decorative panel 200 from moving in the vertical direction (e.g., the Y direction). The anti-loosening block 5 can be made of an elastic material, generating a continuous pre-tightening force when securing the protruding strip 6. Furthermore, the cooperation between the anti-loosening groove 4 and the convex strip 6 forms a damping structure. The elastic deformation of the anti-loosening block 5 absorbs vibration energy, reducing the stress transmitted to the claw 2. The contact surface between the convex strip 6 and the anti-loosening groove 4 dissipates vibration through friction. The clamping force of the anti-loosening block 5 on the convex strip 6 ensures the fit between the trim panel 200 and the recessed structure, ensuring that the gap deviation is controlled within a certain range.

[0045] In one feasible embodiment of this utility model, a guide structure is also included, which is used to guide the trim panel. The guide structure guides the trim panel 200 to accurately engage with the cover 100 via a preset trajectory, allowing the user to easily replace the trim panel 200.

[0046] like Figure 2 and Figure 4 As shown, in a feasible embodiment of this utility model, the guide structure includes a guide groove 7 and a guide post 8. One of the guide groove 7 and the guide post 8 is disposed on the recessed structure, and the other is disposed on the decorative panel 200. The guide post 8 is located on the side of the decorative panel 200 opposite to the recessed structure. Specifically, the guide post 8 is tapered. The tapered head of the guide post 8 forms a self-centering guide with the chamfered entrance of the guide groove 7. When the decorative panel 200 is offset, the guide post 8 can automatically slide into the groove along the tapered surface.

[0047] In addition, the cylindrical surface of the guide post 8 and the inner wall of the guide groove 7 are fitted with a clearance to restrict horizontal displacement. The ground of the guide groove 7 and the end face of the guide post 8 form an axial positioning, ensuring that the fitting gap between the trim panel 200 and the recessed structure is small. When the guide post 8 and the guide groove 7 are installed in place, the positioning between the trim panel 200 and the cover 100 is further realized.

[0048] In one feasible embodiment of this utility model, there are at least two guide structures, and the appropriate number can be set according to the length of the sinking structure, which can be two or three.

[0049] like Figures 4-6As shown, in a feasible embodiment of this utility model, a fastener is also included. A first fastening hole 9 is provided on the housing, and a second fastening hole 10 is provided on the decorative panel. The first fastening hole 9 and the second fastening hole 10 are correspondingly arranged, and the fastener passes through both the first fastening hole 9 and the second fastening hole 10. The fastener can be a bolt or screw, passing through the first fastening hole 9 and the second fastening hole 10, forming a three-dimensional fixation with structures such as the claw 2, the slot 3, and the elastic support protrusion 1. The claw 2 and the slot 3 achieve initial positioning and pre-tightening, while the fastener provides continuous and high-strength axial tensile force, enabling the connection structure to withstand greater external forces and vibration loads.

[0050] In a feasible embodiment of this utility model, the top of the anti-loosening block 5 has an inclined transition surface, which can serve as an assembly guide structure. When the protrusion 6 of the decorative panel 200 is inserted into the anti-loosening groove 4, it automatically aligns with the slot position due to the guiding effect of the inclined transition surface. Under vibration, the inclined transition surface shell converts the impact force into a tangential force along the inclined surface, avoiding stress concentration at the edge of the top of the anti-loosening block.

[0051] The second aspect of this utility model is to provide an indoor air conditioning unit, including a cover 100, a decorative panel 200, and a connection structure between the cover and the decorative panel as described above.

[0052] The air conditioner indoor unit provided by this utility model has the above-mentioned advantages due to the connection structure of the cover and the decorative panel as described above.
