Description

TECHNICAL FIELD

[0001] The utility model relates to air conditioner assembly technical field especially relates to air conditioner panel assembly structure and air conditioner. BACKGROUND

[0002] In the assembly design of modern household electrical appliances (such as air conditioner, TV set, refrigerator, etc.), buckle connection is a widely used fixing mode, which realizes the quick assembly and fixing of parts through the interaction of the clasp and the matching structure (usually the card hole).

[0003] According to the material characteristics and structural design of the clasp, the buckle connection is mainly divided into two types of rigid clasp and elastic clasp, and the two have advantages and disadvantages in functional characteristics, application scenarios and design challenges.

[0004] The rigid clasp is a rigid buckle structure, which is usually made of high-strength plastic (such as ABS, PC, POM, etc.), and has high rigidity and strong bearing capacity. The rigid clasp is usually designed as a one-way hook structure, including a fixed arm and a protrusion extending perpendicular to the fixed arm, and is fixed by the interference fit between the protrusion and the matching surface. Although it has the advantage of high strength, it is difficult to assemble.

[0005] The elastic clasp is a flexible buckle structure, which is usually made of elastic material (such as TPE, TPU, silicone rubber, etc.), and is usually designed as a cantilever beam structure, which realizes assembly and fixing through the bending deformation of the elastic arm. The panel and the face frame are tightly matched by the elastic clasp, and the elastic arm is easily deformed due to the weak strength of the elastic clasp, which causes the assembly structure to have gaps and affects the appearance.

[0006] At present, the panel and the face frame are usually assembled by using multiple independent elastic clasps and multiple independent rigid clasps in combination, which is undoubtedly increased the number of clasps, increased the production cost, and increased the installation difficulty. UTILITY MODEL CONTENTS

[0007] In order to solve the technical problems that the existing assembly structure uses multiple independent elastic clasps and multiple independent rigid clasps in combination, which causes too many clasps, low assembly efficiency and increased production cost, the utility model provides an air conditioner panel assembly structure and air conditioner which improves the assembly efficiency and reduces the number of clasps.

[0008] The technical scheme adopted by the utility model to solve its technical problems is:

[0009] An air conditioner panel assembly structure includes a panel and a frame. The panel has at least one part that abuts against the frame. The panel is provided with a rigid clip, which includes a fixing arm and a locking part extending perpendicularly to the fixing arm. The frame is provided with a corresponding locking hole. One end of the rigid clip with the locking part is inserted into the locking hole. The locking part engages with the inner surface of the frame. There is a gap between the locking part and the inner surface of the frame. The locking part is provided with an elastic protrusion. When the rigid clip engages with the locking hole, the elastic protrusion is in a compressed state and undergoes elastic deformation. The elastic protrusion contacts the inner surface of the frame.

[0010] Furthermore, the panel is equipped with multiple rigid clips.

[0011] Furthermore, when the panel is placed horizontally, there are three rigid clips arranged in a straight line at intervals on the left side of the panel, and three rigid clips arranged in a straight line at intervals on the right side of the panel.

[0012] Furthermore, the elastic protrusion is made of silicone rubber and is fixedly connected to the locking part.

[0013] Furthermore, the elastic protrusion has a convex hull shape.

[0014] Furthermore, multiple elastic protrusions are provided.

[0015] This utility model also provides an air conditioner, including the air conditioner panel assembly structure described in any of the above embodiments.

[0016] The beneficial effects of this utility model are:

[0017] By designing an elastic protrusion on the locking part of the rigid clip, the functions of rigid and elastic clips are integrated, combining the advantages of both. It possesses the high strength of the fixing arm of a rigid clip and the ease of fixation through elastic deformation of an elastic clip. This avoids the low installation efficiency and high installation difficulty caused by interference fits in traditional rigid clips, and also avoids the easy deformation of the elastic arm in traditional elastic clips, which can lead to insecure fixing of the panel and frame, resulting in installation gaps and affecting the appearance. This structure not only reduces the number of clips and lowers mold costs, but also improves assembly efficiency and appearance quality, demonstrating significant technical advantages and application value.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the present invention will be further described below with reference to the accompanying drawings.

[0025] First, it should be stated that the technical solutions of the embodiments of this application are clearly and completely described. The described embodiments are only some of the embodiments of this application, and not a limitation of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this utility model.

[0027] It should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "connection" and "fixation," etc., should be interpreted broadly. For example, "fixation" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Reference Figures 1 to 5 This utility model provides an air conditioner panel assembly structure and an air conditioner.

[0029] like Figures 1 to 4As shown in the embodiment of this solution, the air conditioner panel assembly structure includes a panel 1 and a frame 2. The panel 1 has at least one part that abuts against the frame 2. The panel 1 is provided with a rigid clip 3. The rigid clip 3 includes a fixing arm 31 and a locking part 32 extending perpendicularly to the fixing arm 31. The frame 2 is provided with a locking hole 4 corresponding to the rigid clip 3. One end of the rigid clip 3 with the locking part 32 is inserted into the locking hole 4. The locking part 32 engages with the inner surface of the frame 2. There is a gap between the locking part 32 and the inner surface of the frame 2. The locking part 32 is provided with an elastic protrusion 5. When the rigid clip 3 engages with the locking hole 4, the elastic protrusion 5 is in a compressed state and generates elastic deformation. The elastic protrusion 5 contacts the inner surface of the frame 2.

[0030] This design, based on the traditional rigid clip 3's fixing arm 31 and locking part 32, adds an elastic protrusion 5. It combines the high strength of the rigid clip 3's fixing arm 31 with the easy-to-fix feature of the elastic clip's elastic deformation. This avoids the low installation efficiency and high installation difficulty of the traditional rigid clip 3 relying on interference fit, and also avoids the easy deformation of the elastic arm of the traditional elastic clip, which can lead to insecure fixing of the panel 1 and frame 2, resulting in installation gaps and affecting the appearance.

[0031] For panel 1, at least one part abuts against frame 2, such as Figure 1 As shown, the panel 1 may have a limiting plate on its side, which abuts against the face frame 2 and then is engaged with the inner surface of the face frame 2 by the locking part 32, thereby fixing the panel 1 and the face frame 2 together. Alternatively, it may be set in other parts of the panel 1. There are no special limitations here, as long as the limiting purpose can be achieved.

[0032] like Figure 3 As shown, one or more rigid clips 3 can be provided, preferably six. When the panel 1 is placed horizontally, there are three rigid clips 3 arranged in a straight line at intervals on the left side of the panel 1, and three rigid clips 3 arranged in a straight line at intervals on the right side of the panel 1. This ensures even pressure distribution and a more stable connection between the panel 1 and the frame 2.

[0033] Furthermore, the elastic protrusion 5 is made of silicone rubber and is fixedly connected to the locking part 32. In addition to silicone rubber, natural rubber, thermoplastic elastomers, or other materials with a certain degree of elasticity can also be used.

[0034] like Figure 2 As shown, the elastic protrusion 5 has a convex shape. When the elastic protrusion 5 is designed as a convex shape, it offers several advantages. First, the smooth curved surface of the convex shape reduces wear and extends service life; it possesses good compression recovery performance, ensuring long-term reliability; and it adapts to uneven surfaces, reducing installation difficulties. Furthermore, the convex shape design is not only aesthetically pleasing but also simple to manufacture, helping to reduce costs.

[0035] Furthermore, multiple elastic protrusions 5 are provided. Three or more elastic protrusions 5 can be provided to improve elasticity and prevent the elasticity from decreasing due to wear.

[0036] For the elastic protrusion 5, grooves or cuts can be made around the elastic protrusion 5 to give the elastic protrusion 5 a larger deformation space or deformation amount, thereby improving the elasticity of the elastic protrusion 5.

[0037] like Figure 5 As shown, this utility model also provides an air conditioner, including the air conditioner panel assembly structure described in any of the above embodiments. The specific structure of this air conditioner panel assembly structure is the same as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0038] This solution is compared with traditional rigid clips and traditional flexible clips:

[0039] The elastic modulus of a traditional rigid clip 3 (ABS material) is approximately 2-3 GPa, while that of a traditional elastic clip (TPE material) is approximately 0.1-0.5 GPa. This patent reduces the equivalent elastic modulus of the elastic portion to 0.8-1.2 GPa by providing a local elastic zone, i.e., an elastic protrusion 5, on the locking part 32, thereby maintaining 60% of the stiffness of a traditional rigid clip 3 while achieving 30% of the deformation capacity of a traditional elastic clip.

[0040] When the size fluctuates by ±0.5mm, the local elastic zone can absorb a displacement deviation of 0.3-0.4mm (measured by a laser displacement sensor), and the residual deviation is borne by the rigid body.

[0041] Traditional designs require 6-8 clips per side (spaced approximately 80mm apart). This application increases the clip load-bearing capacity by 40% (three-point bending test) through a composite structure, allowing the number of clips to be reduced to 3-5 (spaced 120mm apart). Under the same load, the maximum stress distribution of the clips in this design is more uniform, and the stress concentration factor is reduced from 2.8 to 1.5, allowing for a reduction in the number of clips without affecting structural strength.

[0042] Measurements using a white light interferometer showed that the clearance pass rate of the traditional rigid clamp 3 was 78% with a tolerance of ±0.3mm; the clearance pass rate of the traditional elastic clamp was 92% with a tolerance of ±0.5mm, but the maximum deformation exceeded the standard; the clearance pass rate of this solution was 89% with a tolerance of ±0.5mm, and the deformation was controlled within 0.15mm.

[0043] By measuring the assembly insertion force, the traditional rigid clip 3 requires an insertion force of 12-15N, while this solution requires an insertion force of 8-10N (a reduction of about 33%), making assembly insertion easier.

[0044] By measuring the holding force, the traditional rigid clip 3 has a holding force of 50N, the traditional elastic clip has a holding force of 30N, and the holding force of this solution is 45N, which is 90% of that of the traditional rigid clip 3.

[0045] After 1000 insertion and removal tests, the retention force attenuation rate is less than 5% (better than the 15% attenuation of traditional elastic clips).

[0046] Mold complexity: Compared with traditional rigid clips and traditional elastic clip structures, the mold cost of this solution is reduced by about 40%.

[0047] Injection molding cycle: Injection molding cycle time reduced by approximately 30%.
