Description

Technical Field

[0001] This utility model relates to the technical field of accordion storage boxes, and in particular to an anti-collision storage box for accordions. Background Technology

[0002] As a sophisticated and valuable musical instrument, the organ has a complex internal structure, containing numerous reeds, keyboards, bellows, and delicate mechanical transmission components. These components are extremely sensitive to impacts, vibrations, and changes in temperature and humidity. Therefore, a storage case with excellent protective properties is crucial during transportation and storage.

[0003] Reference publication number: CN218259842U. This utility model discloses an anti-collision storage box for an accordion, comprising an upper box and a lower box. The inner walls of the upper and lower boxes are respectively embedded with a plurality of first longitudinal elastic strips and a plurality of second longitudinal elastic strips. Both the first and second longitudinal elastic strips are U-shaped structures. Connecting components are embedded at both ends of the second longitudinal elastic strips to fix the first and second longitudinal elastic strips. A first transverse elastic strip is fixedly connected to the middle portion of each of the first longitudinal elastic strips, and a second transverse elastic strip is fixedly connected to the middle portion of each of the second longitudinal elastic strips. A hinge mechanism is fixedly connected between one end of each of the first and second transverse elastic strips. The upper and lower boxes are detachably connected by a plurality of snap-fit ​​fasteners. A plurality of airbags are provided in both the inner cavities of the upper and lower boxes. The accordion is fixedly mounted in the inner cavities of the upper and lower boxes by the airbags. This utility model can resist external impacts and has a large deformation redundancy, enhancing the protection of the accordion.

[0004] Although the aforementioned storage box is equipped with multiple ribs to achieve impact resistance, each rib can only provide localized reinforcement, resulting in localized and discontinuous impact resistance. When the storage box is impacted, the stress cannot be effectively transferred and dispersed between the ribs, and stress concentration is likely to occur in the weak areas between the ribs, leading to the breakage of the storage box. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model embodiment is to provide an accordion-type anti-collision storage box, which can solve the technical problem that the storage box ribs are designed in a dispersed manner, the impact resistance provided to the storage box body is relatively local and discontinuous, and the stress cannot be effectively transferred and dispersed between the ribs.

[0006] This utility model embodiment proposes an accordion anti-collision storage box, including: a storage box body and a box lid hinged to the top of it by a hinge; An impact-resistant component is disposed in the interlayer of the storage box body; The impact-resistant components include a reinforcing plate, a wave groove, and an elastic plate. The reinforcing plate has an overall U-shaped design and its side ends are fixed to the inner wall of the storage box body. The wave groove is opened on the surface of the reinforcing plate, making the reinforcing plate have a wave-like design. The elastic plate is located in the wave groove to enhance the impact resistance of the reinforcing plate.

[0007] Preferably, the reinforcing plate is hollow in design and its interior is filled with a filling material.

[0008] Preferably, the filling material is a closed-cell foam material.

[0009] Preferably, the cross-section of the reinforcing plate is continuously wavy, and its amplitude gradually increases from the center to the edge.

[0010] Preferably, the waveform density and plate thickness of the reinforcing plate gradually increase from the center to the edge.

[0011] Preferably, the elastic plate is an arched preload plate, with both ends fixed to the inner wall of the corrugated trough, and a gap between its middle part and the bottom of the corrugated trough.

[0012] Preferably, there are gaps between the front and rear sides of the reinforcing plate and the inner wall of the interlayer of the storage box body.

[0013] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: In this embodiment of the invention, the traditionally dispersed ribs are integrated into a single, wave-shaped anti-reinforcing plate and placed inside the interlayer of the storage box body. This not only effectively distributes the pressure evenly and reduces local damage when the storage box body is impacted, but also maximizes the protective performance by gradually increasing the waveform amplitude, waveform density, and plate thickness of the reinforcing plate from the center to the edge, precisely deploying the strongest structural strength and energy absorption capacity at the corners of the storage box body where collisions are most likely to occur.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0021] Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts disclosed in this utility model.

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention.

[0023] Reference manual attached Figures 1 to 4 The present invention provides a structure for an accordion-style shockproof storage box, comprising: a storage box body 100 and a box lid 110 hinged to the top thereof.

[0024] Impact-resistant component 200 is disposed in the interlayer of the storage box body 100.

[0025] The impact-resistant component 200 includes a reinforcing plate 210, a wave groove 211, and an elastic plate 212. The reinforcing plate 210 has an overall U-shaped design and its side ends are fixed to the inner wall of the storage box body 100. The wave groove 211 is opened on the surface of the reinforcing plate 210, making the reinforcing plate 210 a wave-like design. The elastic plate 212 is located in the wave groove 211 to enhance the impact resistance of the reinforcing plate 210.

[0026] In this embodiment of the utility model, compared with the isolated and discrete ribs in the prior art, the U-shaped design and integral reinforcing plate 210 has a continuous wave structure that can absorb energy through overall elastic deformation when impacted, and the force flow can be smoothly transmitted along the wave groove 211, effectively avoiding stress concentration in local areas, thereby significantly improving the overall impact resistance of the storage box body 100.

[0027] In one possible implementation, the cross-section of the reinforcing plate 210 is continuously wavy, and its amplitude gradually increases from the center to the edge.

[0028] In this embodiment of the utility model, considering that when the storage box body 100 is dropped or collided, the probability and intensity of the impact on its corners are much greater than that on the center, by increasing the wave amplitude of the edge area, it is equivalent to providing a larger material deformation space and better structural flexibility in these key areas, thereby absorbing more impact energy and achieving a gradient protection effect of key areas and key protection.

[0029] In one possible implementation, the waveform density and plate thickness of the reinforcing plate 210 gradually increase from the center to the edge.

[0030] In this embodiment of the utility model, in order to further enhance the effect of the above-mentioned gradient protection, this embodiment further strengthens the corrugation density and plate thickness of the reinforcing plate 210 on the basis of the above-mentioned wave amplitude. Together, the edge area of ​​the reinforcing plate 210 can be constructed into an anti-collision structure. When facing the most severe corner impact, it can provide a gradually enhanced and huge energy absorption capacity, and prevent structural damage to the storage box body 100 to the greatest extent and protect the internal musical instruments.

[0031] In one possible implementation, the reinforcing plate 210 is hollow, and its interior is filled with a filler material 213. The filler material 213 is a closed-cell foam material.

[0032] In this embodiment of the invention, closed-cell foam is lightweight and low in cost, and effectively absorbs energy through recoverable deformation when its cell structure is compressed. It also provides heat insulation and sound insulation, creating a more stable microenvironment for the accordion.

[0033] In one possible implementation, the elastic plate 212 is an arched preload plate, with both ends fixed to the inner wall of the corrugated groove 211, and a gap between its middle part and the bottom of the corrugated groove 211.

[0034] In this embodiment of the utility model, the prestressed plate itself is in a prestressed state. When subjected to a small impact, it can provide excellent initial support stiffness. When the impact force is too large, the prestressed plate will quickly deform or be further flattened. This instantaneous dynamic process will absorb and dissipate huge impact energy, thereby achieving efficient overload protection and improving the ultimate protection capability of the impact-resistant component 200.

[0035] In one possible implementation, gaps exist between the front and rear sides of the reinforcing plate 210 and the inner wall of the interlayer of the storage box body 100.

[0036] In this embodiment of the utility model, the above design provides the necessary space for the reinforcing plate 210 to deform when it is impacted, avoiding rigid blockage and further improving the shock absorption performance of the storage box.

[0037] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and not to limit it. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
