Description

Technical Field

[0001] This utility model relates to the field of aviation case technology, and in particular to an aviation case with a cushioning structure. Background Technology

[0002] In the transportation and warehousing of professional equipment such as LED displays, audio equipment, and lighting equipment, flight cases are the core packaging tools to ensure the integrity of the equipment. They must simultaneously meet three core requirements: structural stability (protecting internal equipment), ease of operation (facilitating loading and unloading), and low noise (reducing operational and transportation interference). Existing flight cases typically consist of only an upper cover and a lower body, with no cushioning design between the two. When the cover and body are closed, their edges directly contact and collide, generating a noticeable noise of 65-75dB. Frequent opening and closing operations over a long period not only easily lead to operator fatigue but also accelerate the wear of metal edges, shortening the lifespan of the flight case. Furthermore, relative shaking during transportation can cause internal equipment (such as precision components of LED displays) to be damaged by vibration, reducing the stability of the equipment during storage. Therefore, this utility model proposes a flight case with a cushioning structure. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a flight case with a buffer structure. By adding a buffer structure between the lid and the case body, the problems of collision noise, operator fatigue, and shaking are solved at the source, thereby improving the overall performance and market competitiveness of the flight case.

[0004] To address the problems mentioned in the background section and achieve the aforementioned technical objectives, this utility model provides the following technical solution:

[0005] A flight case with a cushioning structure includes a case body and a lid, the lid being closed to the case body; a cushioning structure is provided between the lid and the case body, the cushioning structure including a raised strip, a recessed strip, and a buffer strip, the raised strip and the recessed strip being interlocked, the buffer strip being disposed on the raised strip or the recessed strip; one of the raised strip and the recessed strip is disposed around the opening of the case body, and the other is disposed around the opening of the lid body; when the lid is closed to the case body, the raised strip is interlocked in the recessed strip, and the buffer strip simultaneously contacts the raised strip and the recessed strip.

[0006] Furthermore, the convex strip is provided around the opening of the box body, and the concave strip is provided around the opening of the cover body.

[0007] Furthermore, the concave strip is provided with a groove and a limiting groove. The limiting groove is located on the bottom side of the groove, and the opening of the limiting groove is connected to the bottom of the groove. The buffer strip is located in the limiting groove. When the cover is closed with the box body, the convex strip is inserted into the groove, and the convex strip is in contact with the buffer strip.

[0008] Furthermore, the top of the buffer strip is provided with a concave portion that matches the shape of the convex strip.

[0009] Furthermore, the buffer strip is made of rubber.

[0010] Furthermore, both the convex strip and the concave strip are made of aluminum.

[0011] The beneficial effects of this utility model are as follows: This utility model restricts the relative displacement between the cover and the box by precisely interlocking the convex and concave strips, enhances the structural sealing, suppresses the relative shaking of the cover and the box during transportation, and improves the protection effect on the internal equipment; the convex and concave strips also form an elastic fit through the buffer strip, which absorbs the impact force when closing, avoids direct collision between the box and the cover, and reduces the noise of closing.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] like Figures 1 to 6As shown, a flight case with a cushioning structure includes a case body 1 and a lid 2. The lid 2 and the case body 1 are a mating structure that can be closed. The lid 2 can rotate around a hinged axis or other opening and closing structure on one side of the case body 1 to realize the opening and closing of the flight case, which is used to accommodate and protect internal items, such as LED displays, stage lights, etc. A cushioning structure is provided between the lid 2 and the case body 1, which includes a raised strip 3, a recessed strip 4, and a cushioning strip 5.

[0020] Both the raised strip 3 and the recessed strip 4 are made of aluminum and processed into a preset shape through extrusion molding and precision cutting. The raised strip 3 is a long strip with an arc-shaped top, and the recessed strip 4 is a long strip with a concave portion. The high strength of the aluminum material ensures that the raised strip 3 and the recessed strip 4 will not deform during long-term use, guaranteeing structural stability and precise interlocking, and avoiding buffer failure due to structural deformation. The raised strip 3 and the recessed strip 4 are a matching interlocking structure. The length and direction of the raised strip 3 and the recessed strip 4 are perfectly matched, and they are continuously arranged around the perimeter of the box opening / lid opening to form a ring structure, ensuring precise interlocking when the lid is closed. In this embodiment, the raised strip 3 is fastened to the perimeter of the box opening of the box body 1 by screws, that is, the edge of the top opening of the box body 1; the recessed strip 4 is fastened to the perimeter of the lid opening of the lid body 2 by screws, that is, the edge where the bottom of the lid body 2 meets the box body 1. In other embodiments, the installation positions of the raised strip 3 and the recessed strip 4 can also be interchanged, that is, the recessed strip 4 is fixed around the perimeter of the box opening of the box body 1, and the raised strip 3 is fixed around the perimeter of the lid opening of the lid body 2.

[0021] The buffer strip 5 is made of rubber, preferably nitrile rubber (NBR) or ethylene propylene diene monomer (EPDM). Nitrile rubber has excellent oil resistance and is suitable for audio equipment; EPDM has outstanding weather resistance and waterproof performance, making it suitable for outdoor or humid environments, such as the transportation of outdoor performance equipment. The buffer strip 5 can be fixed to the surface of the convex strip 3 or the interior of the concave strip 4 by adhesive, snap-fit, or embedding, and its length is consistent with that of the convex strip 3 / concave strip 4. In this embodiment, the buffer strip 5 is located in the recessed part of the concave strip 4. When the cover 2 is closed with the cabinet 1, the convex strip 3 is inserted into the concave strip 4 and squeezes the buffer strip 5, so that the buffer strip 5 contacts both the convex strip 3 and the concave strip 4 at the same time. The convex strip 3 and the concave strip 4 form an elastic fit through the buffer strip 5, realizing the buffering effect between the cabinet 1 and the cover 2. In other embodiments, the buffer strip 5 can also be provided on the surface of the convex strip 3. When the cover 2 is closed with the box 1, the recessed part of the concave strip 4 presses the buffer strip 5, which can also achieve the buffering effect; or the buffer strip 5 can be provided on both the convex strip 3 and the concave strip 4 to further enhance the buffering effect.

[0022] When the flight case of this embodiment is opened, the cover 2 rotates upward around the hinge axis, the protruding strip 3 gradually disengages from the concave strip 4, the contact relationship between the buffer strip 5 and the protruding strip 3 / concave strip 4 is released, and the cover 2 rotates to a preset stable angle, then the internal equipment can be taken out and put in. When closing the cover 2, the cover 2 is rotated downward, so that the protruding strip 3 is aligned with the opening direction of the concave strip 4 and gradually inserted; as the closing action progresses, the insertion depth of the protruding strip 3 and the concave strip 4 gradually increases until it is fully closed. The precise insertion and cooperation of the protruding strip 3 and the concave strip 4 restricts the relative displacement between the cover 2 and the case 1, and also enhances the structural sealing, reduces the gaps in which external dust and moisture enter the flight case, and improves the moisture and dust protection of the internal equipment. The protruding strip 3 and the concave strip 4 are also elastically engaged by the buffer strip 5. The buffer strip 5 absorbs the impact force when closing, avoids direct collision between the case 1 and the cover 2, and reduces closing noise; the elastic deformation of the buffer strip 5 can also suppress slight vibrations during transportation and limit the relative swaying of the cover 2 and the case 1.

[0023] In this implementation plan, see Figure 5 and Figure 6 The concave strip 4 is formed by aluminum extrusion molding, and has a groove 41 and a limiting groove 42 integrally formed. The groove 41 is located on the side of the concave strip 4 facing the convex strip 3, and the width of the groove opening is adapted to the cross-sectional width of the convex strip 3. The limiting groove 42 is located inside the concave strip 4 and is located on the bottom side of the groove 41. The opening of the limiting groove 42 is connected to the bottom of the groove 41, forming a vertically connected structure between the groove 41 and the limiting groove 42. The buffer strip 5 is embedded in the limiting groove 42 by an interference fit. When the cover 2 and the box 1 are closed, the convex strip 3 is inserted into the groove 41, and the convex strip 3 is in contact with the buffer strip 5.

[0024] During the closing process of the cover 2 and the box 1, the protruding strip 3 is inserted along the opening of the groove 41 of the concave strip 4, and first contacts the top surface of the buffer strip 5 in the limiting groove 42; as the closing force increases, the protruding strip 3 continues to press down on the buffer strip 5, and the buffer strip 5 undergoes elastic deformation in the limiting groove 42 and absorbs the impact force between the protruding strip 3 and the concave strip 4; when the cover is in place, the bottom of the protruding strip 3 is fully in contact with the buffer strip 5, the buffer strip 5 is kept in a slightly compressed state, and at the same time forms a double contact with the protruding strip 3 and the concave strip 4. The elastic deformation of the buffer strip 5 can offset the relative vibration of the protruding strip 3 and the concave strip 4 in real time, avoiding hard collision.

[0025] In this implementation plan, see Figure 6 The top of the buffer strip 5 is integrally formed with a concave portion 51 that matches the shape of the protruding strip 3. When the cover 2 is closed with the box 1, the protruding strip 3 is embedded in and squeezes the bottom and side wall of the concave portion 51 to form a conformal fit. The side wall of the concave portion 51 restricts the lateral displacement of the protruding strip 3, and the bottom absorbs the longitudinal impact force, making the impact force transmission more uniform and the buffering effect more stable.

[0026] In other implementations, the convex strip 3 and / or concave strip 4 may also be made of elastic material, so that they have the dual functions of "structural support" and "buffer strip 5", and achieve the buffering effect through their own deformation, without the need for additional setting and installation of a separate buffer strip 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
