Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning equipment, and in particular to a ceiling-mounted unit panel assembly structure. Background Technology
[0002] Ceiling-mounted air conditioners are a widely used type of light commercial air conditioner. They typically have a panel for air intake and exhaust. Currently, there are two main structural forms for ceiling-mounted unit panels. The first consists of an integrated panel frame and a central air intake grille. The second involves first forming a panel frame with an upper and lower panel, and then installing the air intake grille in the center of the upper panel. Considering the convenience of installation and maintenance of the exhaust components, the second method is currently the primary choice. In the second method, the upper and lower panels also have two structural forms: one is a snap-fit connection, such as the ceiling-mounted unit panel exhaust structure disclosed in patent document CN221279645U. However, a simple snap-fit connection lacks stability, is prone to noise due to vibration during air conditioner operation, and also carries the risk of detachment; the other is a connection using multiple screws. A simple screw connection is more cumbersome during production assembly and subsequent disassembly and maintenance, and sometimes requires a separate cover to prevent screw exposure. Utility Model Content
[0003] To overcome the aforementioned shortcomings of existing ceiling panel mounting systems, the technical problem to be solved by this utility model is to provide a ceiling panel mounting structure that is easy to assemble and stable and reliable.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A ceiling-mounted air conditioning panel assembly structure includes a lower panel and an upper panel, both of which are frame-shaped, and a suction grille installed in the central cavity of the upper panel. The upper panel has outwardly protruding portions at its four corners, with first buckles on the inner side of the protrusions. The inner side of the upper panel, along the edge of its central cavity, has a positioning frame that can extend into and match the central cavity of the lower panel. Multiple second buckles are spaced apart on the outer wall of the positioning frame. Multiple screw posts are spaced apart on the upper plate outside the positioning frame. The lower panel has first locking blocks at its four corners that match the first buckles. The side wall of the central cavity of the lower panel has second locking blocks that match the second buckles. The edge of the central cavity of the lower panel has screw holes that match the screw posts.
[0006] Furthermore, the protrusion has a 90° fan-shaped structure, and each protrusion is provided with two first buckles, located at both ends of the fan-shaped structure. The four corners of the lower panel are provided with fan-shaped grooves that match the protrusion.
[0007] Furthermore, the two first buckles on the protrusion are inclined outward at both ends of the protrusion, and the first locking block is set on the sidewalls of both ends of the fan-shaped groove of the bottom plate. The outer surface of the first locking block is provided with multiple triangular ribs for guiding the first buckles.
[0008] Furthermore, the second buckle is provided with three on each of the left and right sides of the positioning frame, one on each of the front sides near the two ends, and one in the middle of the rear side. The screw post includes three, one of which is located in the middle of the front side of the positioning frame, and the other two are located in the rear side of the positioning frame near the two ends.
[0009] Furthermore, the second latch on the lower plate that matches the second latches on the left and right sides and the front side of the positioning frame is an elastic latch, with a reinforcing rib between its inner bottom and the lower panel. The second latch on the lower plate that matches the second latch on the rear side of the positioning frame is a fixed latch.
[0010] Furthermore, an angled groove is provided on the lower plate on one side of the elastic block.
[0011] The beneficial effects of this utility model are: the structure of using a snap-fit structure and screw connection can ensure both the convenience of assembly and the reliability of the connection between the upper panel and the lower panel. In addition, by reasonably arranging the position and snap-fit form of the snap-fit, only a few screws are needed to achieve the stability of the structure. Moreover, the screws are installed on the inside of the upper panel and between the lower panel, so there will be no exposed screws, which will not affect the appearance quality of the ceiling machine.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] It should be noted that if this utility model contains directional indicators such as up, down, left, right, front, and back, these are used to describe the relative positional relationships between components and are not specific references to the absolute positions of related components or the positional relationships between components. They are only used to explain the relative positional relationships and movement of components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. If this utility model contains terms related to quantity, such as "many," "multiple," or "several," these specifically refer to two or more.
[0023] like Figure 1-7 As shown, the ceiling panel assembly structure provided by this utility model includes a lower panel 1 and an upper panel 2, both of which are frame-shaped structures, and a suction grille 3 installed in the central cavity of the upper panel 2. The upper panel 2 has outwardly protruding parts 21 at its four corners, and a first buckle 22 is provided on the inner side of the protruding parts 21. The inner side of the upper panel 2 is provided with a positioning frame 23 along the edge of its central cavity, which can extend into and match the central cavity of the lower panel 1. A plurality of second buckles 24 are spaced apart on the outer side wall of the positioning frame 23. A plurality of screw posts 25 are spaced apart on the upper panel 2 outside the positioning frame 23. The lower panel 1 has a first locking block 11 at its four corners that matches the first buckle 22. The side wall of the central cavity of the lower panel 1 has a second locking block 12 that matches the second buckle 24. The edge of the central cavity of the lower panel 1 has screw holes 13 that match the screw posts 25.
[0024] The upper panel 2 is connected to the lower panel 1 via a first latch 22 on the protrusion 21 engaging with a first latch 11, and the middle of the upper panel 2 is connected to the lower panel 1 via a second latch 24 engaging with a second latch 12, thus ensuring uniform engagement between the lower panel 1 and the upper panel 2. The positioning frame 23 provides positioning and elasticity, ensuring that the second latch 24 and the second latch 12 are aligned and tightly engaged. Furthermore, the screw post 25 is positioned inside the upper panel 2. During assembly, the worker inserts their hand into the cavity in the middle of the upper panel 2, then inserts the screw from the inside out through the screw hole 13, and connects it to the screw post 25, preventing the screw from being exposed.
[0025] like Figure 2 As shown, the protrusion 21 has a 90° fan-shaped structure. Each protrusion 21 is provided with two first buckles 22, located at both ends of the fan-shaped structure. The four corners of the lower panel 1 are provided with fan-shaped grooves 14 that match the protrusions 21. The two ends of the fan-shaped structure of the protrusion 21 correspond to the two ends of the ceiling air outlet. The first buckles 22 at this location can enhance the structural strength of the two ends of the air outlet and prevent the edge of the upper panel 2 from loosening with the lower panel due to excessive wind force.
[0026] like Figure 6 , Figure 4 As shown, to facilitate engagement, the two first latches 22 on the protruding part 21 are inclined outwards at both ends of the protruding part 21. The first locking block 11 is disposed on the sidewalls at both ends of the fan-shaped groove 14 of the bottom plate 1. The outer surface of the first locking block 11 is provided with multiple triangular ribs 15 for guiding the first latches 22. The outward inclination of the first latches 22 can improve the elastic force. At the same time, by providing triangular ribs 15 on the lower outer side of the first locking block 11, the first locking block 11 can be strengthened and the assembly guide can be provided. During the engagement process, the triangular ribs 15 press the first latches 22 inwards through the inclined surface, so that they can smoothly engage with the first locking block 11, ensuring the convenience and stability of the engagement.
[0027] Specifically, when arranging the second clip 24 and screw post 25, they can be set up as follows: Figure 2 As shown, three second latches 24 can be provided on each of the left and right sides of the positioning frame 23, one on each side near the two ends of the front side, and one in the middle of the rear side. Three screw posts 25 are included, one located in the middle of the front side of the positioning frame 23, and the other two located on the rear side of the positioning frame 23 near the two ends. The corresponding arrangement of the second latch 12 and screw holes 13 is as follows... Figure 3 As shown, these correspond to the second clip 24 and the screw post 25, respectively. Thus, each side of the upper panel 2 has three connection points, ensuring strong connection with the lower panel 1. Furthermore, only three screws are needed, making assembly and disassembly convenient.
[0028] A more preferred embodiment is that the second latching block 12 on the lower panel 1, which matches the second latches 24 on the left, right, and front sides of the positioning frame 23, is an elastic latching block, with a reinforcing rib 16 between its inner bottom and the lower panel 1. The second latching block 12 on the lower panel 1, which matches the second latches 24 on the rear side of the positioning frame 23, is a fixed latching block. An elastic latching block refers to... Figure 7 As shown, it is connected to the lower panel 1 only through the bottom and reinforcing rib 16, and can generate elastic deformation around the bottom within a certain range; the fixing block is a fixed structure, such as Figure 8 As shown, the elastic deformation that can be generated is relatively small. By setting elastic blocks on three sides of the lower panel 1 and a fixed block on one side, it can accommodate errors and slight deformations during production and assembly, ensuring a stable and secure connection between the upper panel 2 and the lower panel 1. In addition, an angled guide can be provided on the inner top of the elastic block to facilitate sliding assembly. At the same time, for easy disassembly, an angled groove 17 is provided on the lower panel 1 on one side of the elastic block. During disassembly, a tool such as a flathead screwdriver can be inserted into the angled groove 17 and then the second latch 24 can be pried outward to disengage it from the second latch 12.
[0029] In summary, this utility model achieves a stable connection between the upper panel 2 and the lower panel 1 with only a few screws by reasonably arranging the position and snap-fit method of the buckles. Furthermore, it is easy to assemble and disassemble, and has good practicality and application value.
