Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing 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 this utility model.

[0018] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] To facilitate manufacturing and assembly, the casing of an air conditioner indoor unit typically employs a modular assembly structure. This casing generally includes a front frame and a pair of end caps mounted on the left and right sides of the front frame. To achieve a simple and streamlined overall design, the outer surfaces of the two end caps are usually required to be precisely aligned and smoothly transitioned with the front face of the front frame, thus forming a complete and smooth decorative surface.

[0021] Because the end cap, especially its lower edge near the bottom of the frame, lacks a secure fixation, this lower edge is highly susceptible to deformation when the indoor unit is subjected to vibration or accidental impact. This can cause warping or misalignment relative to the bottom of the frame. This not only reduces the sealing and structural stability of the indoor unit but also severely compromises its overall aesthetic design and flatness, diminishing the user's visual experience. Furthermore, the front edge of the end cap is prone to mutual compression or collision with the frame, increasing the risk of casing damage, shortening its lifespan, and potentially causing abnormal noises during operation.

[0022] To address the aforementioned problems, some embodiments of this utility model propose a faceplate assembly 1000, suitable for an air conditioner indoor unit 2000. This assembly enhances the deformation resistance of the bottom wall edge of the end cover, preventing deformation of the bottom wall edge. See details below. Figures 1 to 7 The diagram illustrates the front frame component 1000.

[0023] For ease of description, the following description will use the application of the faceplate assembly 1000 to the indoor unit 2000 of an air conditioner as an example. (Refer to...) Figure 1 As shown in the present invention, in this embodiment, the face frame assembly 1000 is disposed on the bottom side of the air conditioner indoor unit 2000. It serves as part of the internal frame of the air conditioner indoor unit 2000 and is used to define the accommodating space together with the other structures of the internal frame. The heat exchange module, fan, filter, power module and other components of the indoor unit are all disposed in the accommodating space.

[0024] Reference Figure 2 and Figure 3 As shown in this embodiment of the invention, the face frame assembly 1000 includes a face frame 100 and end caps. The face frame 100 is located on the bottom side of the internal frame of the indoor air conditioner unit 2000, and its bottom wall is the bottom wall of the indoor air conditioner unit 2000. End caps are provided on the left and / or right sides of the face frame 100, and the end caps are used to define the lateral dimension of the internal space within the internal frame of the indoor air conditioner unit 2000. In one example, two end caps are provided, and the two end caps are correspondingly installed on the left and right sides of the face frame 100.

[0025] Reference Figure 3 and Figure 4As shown in this embodiment of the invention, the bottom edge of the end cap and the bottom wall of the face frame 100 are fixedly connected by a first connecting component 300. It should be noted that the first connecting component 300 can be implemented using a locking mechanism with a snap-fit ​​and a latch, or a locking mechanism with a blind hole and a fastener; this embodiment does not limit this. Specifically, the connection between the end cap and the face frame 100 is mainly concentrated in its main body, and its bottom edge is often in a cantilevered state. Therefore, configuring the first connecting component 300 can firmly fix the bottom edge of the end cap and the bottom wall of the face frame 100 together, thereby constraining the bottom edge of the end cap and reducing deformation such as outward expansion and warping of the bottom edge of the end cap.

[0026] In this embodiment of the invention, the first connecting component 300 is configured to be located inside the bottom wall of the face frame 100 or inside the bottom wall of the end cover when the end cover is connected to the face frame 100. It is understood that when the bottom wall of the end cover is fixed to the bottom wall of the face frame 100 via the first connecting component 300, the first connecting component 300 is hidden within the inner space, thereby preventing the first connecting component 300 from being exposed outside the outer casing of the air conditioner indoor unit 2000 and affecting its appearance.

[0027] The face frame assembly 1000 of this utility model provides a first connecting component 300 between the face frame 100 and the end cap. This first connecting component 300 fixes the bottom edge of the end cap to the bottom wall of the face frame 100, thereby adding a support point to the bottom edge of the end cap that can constrain its deformation or displacement. This improves the structural rigidity and deformation resistance of the bottom edge of the end cap, preventing deformation and thus enhancing the connection stability and sealing between the bottom wall of the end cap and the bottom wall of the face frame 100. It also avoids gaps between the face frame 100 and the end cap, improving the assembly accuracy and appearance quality of the face frame assembly 1000. Furthermore, by limiting the deformation of the bottom wall of the end cap, the risk of compression or collision between the bottom wall of the end cap and the bottom wall of the face frame 100 is reduced, thereby minimizing abnormal noise.

[0028] Reference Figure 2 and Figure 3 As shown in this embodiment of the invention, the faceplate 100 includes a main body plate 110 and end plates 120. The main body plate 110 includes the bottom wall structure of the indoor unit 2000 of the air conditioner, and its lower end surface forms a flat appearance surface to fit the overall shape of the air conditioner. The end plates 120 are connected to the ends of the main body plate 110 in the left-right direction. In this embodiment, the end plates 120 located on both sides are integrally injection molded with the main body plate 110, wherein the end plates 120 protrude upward from the main body plate 110.

[0029] Continue to refer to Figure 2 and Figure 3As shown in the embodiment of this utility model, the end cap includes a first cover plate 210 and a second cover plate 220, wherein the first cover plate 210 and the second cover plate 220 are arranged at an included angle. Specifically, the first cover plate 210 is arranged along the vertical direction, and the second cover plate 220 is arranged along the horizontal direction. In one example, the first cover plate 210 and the second cover plate 220 are connected by a bent portion 230. Specifically, one end of the bent portion 230 is connected to the bottom end of the first cover plate 210, and the other end extends downwards towards the side wall of the main body plate 110 and connects with the second cover plate 220.

[0030] Reference Figure 3 As shown, in this embodiment of the present invention, the first cover plate 210 is connected to the side of the end plate 120 facing away from the main body plate 110. The first cover plate 210 is connected to the end plate 120 via a second connecting assembly 400. In one example, the second connecting assembly 400 includes a second snap fastener 410 and a second latching position 420. The second snap fastener 410 protrudes from the side of the first cover plate 210 facing the end plate 120, and the second latching position 420 is formed on the end plate 120. The second snap fastener 410 and the second latching position 420 engage with each other, thereby achieving a detachable connection between the first cover plate 210 and the end plate 120. Figure 5 It is understandable that the first cover plate 210 covers the outside of the end plate 120. Based on this, the outer wall of the first cover plate 210 is the outer surface of the left and right sides of the air conditioner indoor unit 2000.

[0031] Reference Figure 2 As shown in this embodiment of the invention, the second cover plate 220 serves as the bottom wall of the end cap. One end of the second cover plate 220 is connected to the bottom end of the first cover plate 210, and the other end extends toward the main body plate 110 and is connected to the main body plate 110 via the first connecting assembly 300. Specifically, the first cover plate 210 and the second cover plate 220 are integrally formed. To prevent the end of the second cover plate 220 away from the first cover plate 210 from forming a cantilever structure, the first connecting assembly 300 is connected to the main body plate 110 and the second cover plate 220 respectively, limiting the deformation and displacement of the second cover plate 220 and improving the stability of the second cover plate 220.

[0032] Reference Figure 2As shown, in this embodiment of the present invention, the lower end surface of the main body plate 110 is constructed as the bottom surface of the air conditioner indoor unit 2000. In other words, the lower end surface of the main body plate 110 is the lower exterior surface of the air conditioner indoor unit 2000. In this embodiment, the lower end surface of the second cover plate 220 is flush with or smoothly transitions to the lower end surface of the main body plate 110. It should be noted that the flushness or smooth transition between the lower end surface of the second cover plate 220 and the lower end surface of the main body plate 110 means that the lower end surface of the second cover plate 220 and the lower end surface of the main body plate 110 are approximately one piece in appearance, without obvious protrusions or depressions, so that the exterior surfaces on the left and right sides of the air conditioner indoor unit 2000 are smoothly connected to the exterior surface on the bottom side, resulting in a neat and aesthetically pleasing appearance.

[0033] Specifically, continue to refer to Figure 2 As shown, during the assembly of the end cover and the face frame 100, the second cover plate 220 is connected to the main body plate 110 via the first connecting component 300, thereby limiting the deformation of the second cover plate 220 or its displacement relative to the main body plate 110. Based on this, after assembly is completed, due to the fixing effect of the first connecting component 300, the lower end surface of the second cover plate 220 and the lower end surface of the main body plate 110 can remain flush or smoothly transition, and the end cover and the bottom of the face frame 100 can maintain a smooth connection, improving the flatness of the air conditioner's appearance.

[0034] Reference Figure 4 and Figure 6 As shown in this embodiment of the present invention, the first connecting component 300 includes a first latch 320 and a first buckle 310. The first latch 320 is provided on the inner side of the main body plate 110, which provides a positioning and fixing point for the first buckle 310, thereby constraining the displacement of the second cover plate 220. The first buckle 310 protrudes from the side wall of the second cover plate 220 facing the main body plate 110. The first buckle 310 and the first latch 320 are engaged to form a mechanical lock between the second cover plate 220 and the main body plate 110, preventing the second cover plate 220 from separating from the main body plate 110. Specifically, continue to refer to Figure 4 and Figure 6 As shown, in this embodiment of the invention, a lug 111 protrudes from the inner side of the main body plate 110. The lug 111 is an upwardly extending protruding structure. The first latch 320 is configured to have a through hole 112 extending through the lug 111 along the direction of the second cover plate 220 toward the main body plate 110. The through hole 112 can be a rectangular or circular hole. In one example, along the direction of the second cover plate 220 toward the main body plate 110 (i.e., the insertion direction of the second latch 410), the cross-sectional area of ​​the through hole 112 gradually decreases to guide the insertion of the first latch 310.

[0035] Combination Figure 4 and Figure 6It is understood that in this embodiment of the present invention, the upper end face of the main body plate 110 is recessed away from the through hole 112 to form a clearance space 113 for accommodating the first buckle 310. In other words, the clearance space 113 is formed by slightly thinning the local thickness of the main body plate 110. When the first buckle 310 is inserted into the through hole 112, the clearance space 113 can accommodate the end portion of the first buckle 310, thus avoiding interference between the main body plate 110 and the first buckle 310.

[0036] Reference Figure 4 and Figure 7 As shown, in this embodiment of the present invention, the faceplate 100 further includes a baffle 130, which is disposed on the inner side of the main body plate 110 and has a gap between it and the main body plate 110 in the vertical direction. Specifically, a lug 111 is disposed between the baffle 130 and the main body plate 110, and the baffle 130 is connected to the end of the lug 111 away from the main body plate 110. In one example, the main body plate 110, the lug 111, and the baffle 130 are integrally formed. In this embodiment, the baffle 130 protrudes from the main body plate 110 toward the second cover plate 220 to guide the first buckle 310 into the through hole 112. Specifically, refer to Figure 7 As shown, in this embodiment of the invention, the baffle 130 protrudes from the main body plate 110 in the left-right direction, and its protrusion direction corresponds to the installation path of the second cover plate 220. Since the through hole 112 is located between the baffle 130 and the main body plate 110, during the assembly process, the baffle 130 protruding from the main body plate 110 constrains the movement trajectory of the first buckle 310, and the first buckle 310 can slide along the surface of the baffle 130 until it enters the through hole 112 to complete the fastening.

[0037] Reference Figure 4 and Figure 7 As shown, in this embodiment of the present invention, the baffle 130 extends parallel to the main body plate 110 and maintains a distance from the main body plate 110, thus the two cooperate to define a slot 131 with its opening facing the second cover plate 220. Specifically, the main body plate 110 is arranged in the front-rear direction, and based on this, the through hole 112 and the slot 131 are arranged sequentially from back to front, and the two are separated by a partition. The side wall of the second cover plate 220 facing the main body plate 110 is provided with an insert 221 spaced apart from the first buckle 310. The insert 221 protrudes from the side wall of the second cover plate 220, and the shape and size of the insert 221 match those of the slot 131, thus making it suitable for insertion into the slot 131. It can be understood that during the assembly of the end cap, the cooperation between the slot 131 and the insert 221 can guide the end cap to close onto the face frame 100, ensuring that the first buckle 310 will not shift during insertion into the through hole 112.

[0038] Furthermore, referring to Figure 7As shown in this embodiment of the invention, the inner wall of the baffle 130 facing the main body plate 110 is provided with a raised rib 132. The raised rib 132 can be a strip-shaped raised structure, used to contact the insert 221 and generate frictional resistance. When the insert 221 is inserted into the slot 131, the raised rib 132 abuts against the insert 221, and the frictional resistance between the two can limit the insert 221 from dislodging from the slot 131, thereby further improving the connection stability between the second cover plate 220 and the main body plate 110. Reference Figure 7 As shown, in this embodiment of the present invention, the baffle 130 includes a first plate 133 and a second plate 134, which are integrally formed. The first plate 133 mates with the main body plate 110 of the face frame 100, with a portion forming a through hole 112 and the other portion protruding from the main body plate 110 to guide the first buckle 310 into the first latch 320. The second plate 134 mates with the main body plate 110 of the face frame 100, with a portion forming a slot 131 and the other portion protruding from the main body plate 110 to guide the insert block 221 into the slot 131.

[0039] Continue to refer to Figure 7 As shown, in this embodiment of the invention, the minimum distance between the first plate 133 and the main body plate 110 is greater than the minimum distance between the second plate 134 and the main body plate 110. In other words, the width of the through hole 112 is greater than the width of the slot 131. It is understood that when assembling the end cap, the operator does not need to perform very precise alignment; simply aligning the first snap-fit ​​310, which serves as the main connector, roughly with the entrance of this large through hole 112 allows for easy insertion. This large entrance space has a high tolerance for error, avoiding repeated attempts or jamming due to alignment difficulties.

[0040] Combination Figure 7 It is understood that in this embodiment of the invention, part of the space in the through hole 112 is formed by reducing the thickness of the first plate 133. Compared to the second plate 134, the first plate 133 is thinner, therefore it is farther from the main plate 110, and the resulting through hole 112 is naturally wider. The end face of the first plate 133 facing the main plate 110 and the end face of the second plate 134 facing the main plate 110 are connected by a stepped structure 135. It should be noted that the stepped structure 135 may include multiple steps, and the wall surface of the steps can play a guiding and limiting role, reducing the possibility of the first buckle 310 being mistakenly inserted into the slot 131. (Refer to...) Figure 6As shown, in this embodiment of the present invention, the lower end faces of the first buckle 310 and the second cover plate 220 are spaced apart in the vertical direction. In other words, the mounting position of the first buckle 310 on the second cover plate 220 maintains a vertical distance from its lower end face. Specifically, in this embodiment, the first buckle 310 is formed on the upper half of the side wall of the second cover plate 220 facing the main body plate 110, while the lower half of the side wall of the second cover plate 220 facing the main body plate 110 can abut against the side wall of the main body plate 110 when the first buckle 310 and the first fastening position 320 are fastened together. It can be understood that maintaining surface contact between the end face of the second cover plate 220 facing the main body plate 110 and the side wall of the main body plate 110 can reduce the shaking of the second cover plate 220 and further improve the assembly stability. Continue to refer to Figure 6 As shown, in this embodiment of the invention, a reinforcing rib 222 is provided between the end faces of the first buckle 310 and the second cover plate 220 facing the main body plate 110. The reinforcing rib 222 protrudes from the lower side of the first buckle 310, with one end connected to the first buckle 310 and the other end connected to the end face of the second cover plate 220 facing the main body plate 110, thereby improving the bending resistance of the connection area between the first buckle 310 and the second cover plate 220. In this embodiment, an inclined surface 114 is provided on the upper end face of the main body plate 110 near the second cover plate 220. The inclined surface 114 is inclined inward along the direction of the second cover plate 220 towards the main body plate 110. It should be noted that the clearance space 113 can be formed by the inclined surface 114.

[0041] Continue to refer to Figure 6 As shown in this embodiment of the invention, a portion of the inclined surface 114 is configured as part of the inner wall of the through hole 112, and the inclined surface 114 slides in fit with the reinforcing rib 222. Specifically, when the second cover plate 220 moves toward the main body plate 110, the reinforcing rib 222 on the second cover plate 220 first contacts the inclined surface 114 of the main body plate 110. Since the inclined surface 114 is an inwardly inclined guide surface, during the sliding process of the reinforcing rib 222 along the inclined surface 114, the second cover plate 220 is forcibly guided to a preset assembly position, thereby ensuring that the first buckle 310 is accurately inserted into the through hole 112. During this process, the contact surfaces of the inclined surface 114 and the reinforcing rib 222 form a sliding fit relationship, preventing the first buckle 310 from being misaligned due to displacement.
