Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning equipment, in particular to a side plate structure and an air conditioner thereof. Background Art

[0002] The side plate is an important component of the air-conditioning unit. It is located in the evaporator and condenser components and is installed at both ends of the two components. Its function is to set a circular hole inside to pass through and install the copper tube, support the copper tube and transfer heat with the copper tube and its internal materials. The copper tube further exchanges heat with the surrounding environment to achieve the purpose of cooling.

[0003] The side panels are mostly rectangular in structure, with multiple rows of flanged holes inside, and some also have grounding screw holes. Wrapped around the two ends of the two components, the inside is a copper tube and fins. The grounding screw holes often interfere with the fins during the screwing process, causing damage to the fins and affecting the quality. Although the clearance distance has been taken into account in the design of the structure of the two components, the actual assembly process may cause interference due to the deviation of the part size, resulting in the actual gap being smaller than the designed gap. Since the side panels and fins fit tightly, the grounding screws often hit the fins and break them, which is difficult to detect from the outside, posing a hidden danger for the later use of the air conditioner. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a side panel structure and an air conditioner thereof, which can solve the problems of damage to the internal fins during the process of driving the grounding screws on the existing side panels and difficulty in quality inspection.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a side plate structure, the side plate structure includes a side plate main body and a grounding screw hole, the side plate main body is provided with a grounding screw hole, the bottom edge of the grounding screw hole is provided with a boss, the middle part of the boss is provided with a through hole, the through hole is connected to the grounding screw hole, the head of the grounding screw is located on the outside of the boss, and the tip of the screw passes through the inside of the grounding screw hole. The height of the boss can be flexibly adjusted to control the length of the tip of the screw passing through the inside of the grounding screw hole.

[0006] As a further improvement to the present invention, an annular boss is provided on the outer edge of the grounding screw hole, and a through-hole is formed in the middle of the boss, communicating with the grounding screw hole. This annular boss increases the distance between the grounding screw driven into the grounding screw hole and the copper tube and fins, effectively preventing damage to the copper tube and fins.

[0007] As a further improvement of the present invention: the diameter of the inner circle of the boss is smaller than the diameter of the grounding screw head.

[0008] As a further improvement of the present invention: the outer edge of the grounding screw hole is concave around to form an arc-shaped concession portion, and a gap is formed between the arc-shaped concession portion and the thread portion of the grounding screw.

[0009] As a further improvement of the present invention: the diameter of the inner circle of the boss is larger than the diameter of the arc-shaped relief portion.

[0010] As a further improvement of the present invention: the inner edge of the grounding screw hole extends in the axial direction to form a limiting step, a flanging hole is opened in the middle of the limiting step, and the flanging hole is connected to the grounding screw hole.

[0011] As a further improvement of the present invention: the limiting step is provided with a connecting part and a limiting part, a first arc-shaped transition part is provided at the connection between the outer side of the connecting part and the side plate body, an arc-shaped yielding part is provided on the inner side of the connecting part, and a second arc-shaped transition part is provided between the outer side of the connecting part and the limiting part.

The head of the grounding screw is located on the outside of the boss, and the inside of the grounding screw hole is provided with an internal structure such as a fin. The additional boss can flexibly adjust the length of the tip of the screw passing through the inside of the grounding screw hole, thereby increasing the distance between the screw and the internal structure and preventing the screw from being driven too deep and interfering with the internal structure.

[0017] 2. There is no need to change the size of the standard screw parts.

[0025] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0027] In order to solve the technical problems in the prior art of damaging the internal fins during the process of driving the grounding screws into the side plates and the difficulty in manually inspecting whether the fins are damaged by the tips of the grounding screws, the present invention is further described in conjunction with the accompanying drawings and embodiments:

[0028] like Figures 1 to 5As shown, an embodiment of the utility model discloses a side plate structure, which includes a side plate body 10 and a grounding screw hole 20. The side plate body 10 is provided with a grounding screw hole 20, and the bottom edge of the grounding screw hole 20 is provided with a boss 30. A through hole is opened in the middle of the boss 30, and the through hole is connected to the grounding screw hole 20. The head of the grounding screw is located on the outside of the boss 30, and the tip of the screw passes through the inner side of the grounding screw hole 20.

[0029] The height of the boss 30 protruding from the outer edge of the grounding screw hole 20 can be flexibly adjusted to control the length of the tip of the screw passing through the inner side of the grounding screw hole 20 .

[0030] The grounding screw hole 20, the boss 30 and the side plate body 10 are integrally injection molded. The grounding screw hole 20 is punched on the side plate body 10 by cold stamping using a mold, and then the boss 30 is punched on the bottom surface of the grounding screw hole 20. The diameter of the boss 30 is determined according to the head of the grounding screw, and the inner diameter of the boss 30 is smaller than the diameter of the head of the grounding screw.

[0031] The height of the boss 30 is adjusted according to user needs. The height of the boss 30 determines the height of the ground screw. The mold boss 30 can be made into an insert type and can be flexibly replaced according to the user's needs for the height of the boss 30.

[0032] The depth of the screw depends on the length of the screw itself. The disadvantage of using the existing grounding screw hole 20 is that the tip of the grounding screw may interfere with the internal structure on the inside of the side plate, causing damage to the internal structure. Even if a gap is reserved to prevent interference when the two components are designed, it is still possible that the gap is too small after assembly due to part size deviation, and the tip of the screw may break the copper pipe or power cord, etc., and the screw is a national standard part and it is not easy to customize the size.

[0033] The air-conditioning side panel structure provided in this embodiment changes the structure of the existing grounding screw hole 20, specifically by adding a boss 30 on the outer edge of the grounding screw hole 20. The head of the grounding screw is located on the outside of the boss 30, and there is no need to consider changing the size of the grounding screw. In this way, during the screwing process, the head of the grounding screw is raised by the boss 30 structure, and the tip of the grounding screw passes through the grounding screw hole 20 through the through hole of the boss 30, so the distance from the internal structure of the side panel body 10 is increased. From a structural point of view, the quality risk of the grounding screw breaking the internal structure such as the fin is effectively avoided, and the structural foolproofing is effectively avoided.

[0034] Furthermore, the improved side plate structure of the embodiment adds a boss 30 on the bottom surface of the grounding screw hole 20, reducing the overall quality issues caused by component size issues in the two components, relaxing the requirements for component dimensional accuracy, and improving the pass rate of the components and the two components. It also reduces the difficulty of quality inspection of the two components and structurally prevents screws from breaking the fins, thus eliminating this inspection requirement.

[0035] The shape of the boss 30 can be square, convex, conical, truncated cone, etc., and can also be a boss 30 formed by a plurality of fixed blocks arranged around at intervals. It is only necessary to ensure that the boss 30 is formed by the protrusion at the bottom edge of the grounding screw hole 20, and a through hole is provided in the middle of the boss 30 to connect to the grounding screw hole 20, so that the grounding screw is driven into the grounding screw hole 20 through the boss 30. At the same time, the boss 30 formed by the protrusion and extension at the bottom edge of the grounding screw hole 20 can form a gap layer between the head of the grounding screw and the side plate body 10, that is, the head of the grounding screw does not contact the side plate body 10, and the length of the grounding screw driven into the side plate body 10 is changed without customizing the size of the grounding screw.

[0036] In some embodiments, an annular boss 30 is provided on the outer edge of the grounding screw hole 20. A through-hole is defined in the middle of the boss 30, communicating with the grounding screw hole 20. The boss 30 is disposed on the outer periphery of the bottom surface of the grounding screw hole 20. After the grounding screw is driven into the grounding screw hole 20, the head of the grounding screw rests on the boss 30 rather than on the bottom surface of the grounding screw hole 20. The boss 30 increases the distance between the grounding screw driven into the grounding screw hole 20 and the copper tube or fin, effectively preventing damage to the copper tube or fin.

[0037] In some embodiments, an outer edge of the grounding screw hole 20 is concavely formed to form an arc-shaped relief portion 40 , and a gap is formed between the arc-shaped relief portion 40 and the thread portion of the grounding screw.

[0038] In some embodiments, the inner diameter of the boss 30 is larger than the diameter of the arc-shaped relief portion 40 .

[0039] Specifically, the arc-shaped relief portion 40 extends from the bottom surface depression of the grounding screw hole 20 to the inner side of the hole. Furthermore, the upper end of the arc-shaped relief portion 40 extends to the lower edge of the annular boss 30 .

[0040] In some embodiments, the inner edge of the grounding screw hole 20 extends axially to form a limiting step 50. A flanged hole 60 is formed in the middle of the limiting step 50 and communicates with the grounding screw hole 20. The flanged hole 60 effectively prevents the grounding screw from being driven crookedly, ensuring that the screw is driven correctly.

[0041] After the die is cold-stamped to form a pre-hole for the flanging hole on the side plate body 10, the pre-hole is flanging to form a flanging hole 60 of the required diameter and flanging height. An annular boss 30 is punched on the bottom surface of the flanging hole 60. The inner diameter of the boss 30 is larger than the transition range between the flanging hole and the bottom surface to ensure the integrity of the flanging hole.

[0042] In a specific example, Figure 2 and Figure 3The figure shows a comparison between the improved air conditioner side panel structure of this embodiment and that of existing air conditioner side panels. In this embodiment, an annular boss 30 is added to the outer edge of the bottom surface of the side panel grounding screw hole 20. When the screw is driven, the boss 30 contacts the head of the screw, creating a certain distance h between the head of the screw and the bottom of the side panel. This boss 30 effectively raises the screw, increasing the distance h between the screw and the internal structure, preventing the screw from being driven too deep and interfering with the internal structure.

[0043] like Figure 3 As shown, the addition of the boss 30 to the grounding screw hole 20 of this embodiment creates a gap h between the head of the driven screw and the bottom surface of the flanged hole, compared to conventional grounding screw holes 20. This shortens the distance the screw tip extends inwards by h compared to conventional flanged holes, increasing the gap h between the screw tip and the internal structure. This increased distance reduces the likelihood of interference and protects the internal structure. Furthermore, the height h of the boss 30 can be flexibly adjusted by replacing the mold insert to offset dimensional deformation of the side plate.

[0044] like Figure 2 As shown, an annular boss 30 is added where the side plate connects to the screw hole. The inner diameter c of the boss 30 is smaller than the diameter e of the screw head. The flange height f of the flanged hole / flange hole 60 is consistent with that of an ordinary screw hole and is not affected by the boss 30. There is no mandatory requirement for the outer diameter d of the boss 30; it only needs to meet the structural requirements.

[0045] In some embodiments, the limiting step 50 is provided with a connecting portion 501 and a limiting portion 502, a first arc-shaped transition portion 5011 is provided at the connection between the outer side of the connecting portion 501 and the side panel body 10, an arc-shaped yielding portion 40 is provided on the inner side of the connecting portion 501, and a second arc-shaped transition portion 5021 is provided between the outer side of the connecting portion 501 and the limiting portion 502.

[0046] The limiting step 50 is composed of a connecting part 501 and a limiting part 502. The first arc-shaped transition part 5011 is arranged back to back to the arc-shaped giving part 40. The limiting part 502 constitutes the outer wall of the vertical hole. The reliability of screwing is improved through the second arc-shaped transition part 5021 and the first arc-shaped transition part 5011, and the strength of the flanging hole 60 is enhanced.

[0047] In some embodiments, the side plate body 10 has a notch 70 near the outer side of the connecting portion 501, and the notch 70 is connected to the first arc-shaped transition portion 5011. The notch 70 relieves stress at the connection between the ground screw hole 20 and the side plate body 10.

[0048] The embodiment of the utility model further discloses an air conditioner, which comprises the above-mentioned side plate structure.

[0049] The main functions of this utility model are:

[0050] 1. Add a boss at the bottom edge of the grounding screw hole of the side plate body. The boss is provided with a through hole connected to the grounding screw hole. The head of the grounding screw is located on the outside of the boss. The boss structure is used to raise the grounding screw to prevent the tip of the grounding screw from being driven too deep, thereby preventing the tip of the grounding screw from damaging the internal structure.

[0051] 2. By adding a boss, there is no need to customize the size of the grounding screw, so that the tip of the grounding screw is shortened compared to the length of the tip extending inward after the screw is drilled in the existing grounding screw hole, so that the gap between the tip of the grounding screw and the internal structure is increased. The increased distance effectively reduces the probability of interference between the tip of the grounding screw and the internal structure, thereby protecting the internal structure.

[0052] In the description of the present invention, it should be understood that the terms "upper end face", "lower end face", "top", "bottom", "left", "right", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention. Therefore, they cannot be understood as restrictions on the actual use direction of the present invention.

[0053] In summary, after reading the document of this utility model, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of this utility model without creative mental work, which all fall within the scope of protection of this utility model.
