Referring to fig. 3 and 4, in the present embodiment, a buffering structure 30 is disposed in the installation space 141, and is used for buffering the impact kinetic energy of the passengers when the flying device 200 crashes, so as to protect the passengers. The buffer structure 30 includes a first honeycomb core 31. The first honeycomb core 31 is a low-density honeycomb structure, and mainly receives an axial impact force in the cushion structure 30, so that the cushion structure 30 can provide a stable crushing reaction force. First honeycomb core 31 can take place to crumple when receiving external load as an energy-absorbing structure to the realization slows down the impact, is applicable to the protection passenger under the crash operating mode. In other embodiments, the cushioning structure 30 may be disposed on the side of the backrest portion 12 facing away from the seat space 13 (as shown in fig. 2), or the covering portion 14 may be convex toward the cushion portion 11 to form an installation space on the side facing away from the cushion portion 11, in which the cushioning structure 30 may be installed.

Referring to fig. 3 and 5, the first honeycomb core 31 is disposed between the covering portion 14 and the seat portion 11, the first honeycomb core 31 has a first side 311 and a second side 312 opposite to each other, the first side 311 is a side of the first honeycomb core 31 facing the seat portion 11, and the second side 312 is a side of the first honeycomb core 31 facing away from the seat portion 11. The first honeycomb core 31 has a plurality of first honeycomb holes 313, the first honeycomb holes 313 extend in the direction of the own hole axis and penetrate the first side 311 and the second side 312, and the direction of the hole axis of the first honeycomb holes 313 intersects with the seat cushion portion 11. The hole axis direction of the first cell hole 313 is a direction from the first side 311 to the second side 312 or a direction from the second side 312 to the first side 311. It should be understood that in the embodiments provided in the present application, the "honeycomb cell" should not be limited to the honeycomb shape in nature, and it should be essentially understood that the honeycomb core is formed by arranging a plurality of through-hole structures (for example, a porous honeycomb structure formed by densely arranging a plurality of holes), and the shape and size of the plurality of through-hole structures should not be limited by the present specification or the drawings in the specification, for example, some of the through-holes are hexagonal holes, another part of the through-holes are rectangular holes, and the sizes of the plurality of through-holes may also be different; or, the plurality of honeycomb holes in the honeycomb core may include one or a combination of a plurality of holes in the shapes of circular holes, triangular holes, rectangular holes, other polygonal holes, irregular holes, and the like, and the plurality of honeycomb holes are arranged according to a predetermined period to form a generalized honeycomb shape, that is, a honeycomb core in a large dense and arrayed shape, where the predetermined period may be a row and column array, a concentric radiation array, a staggered row and column arrangement, or only a dense arrangement (in sequence, an irregular arrangement or a regular arrangement) on one plane. In the present embodiment, the plurality of first honeycomb holes 313 are all hexagonal shaped holes (e.g., regular hexagons), and the plurality of first honeycomb holes 313 are closely arranged to form the first honeycomb core 31. The first honeycomb holes 313 may have the same or different diameters.

When the first honeycomb core 31 is compressed by the normal force F (in the direction from the first side 311 to the second side 312 or in the direction from the second side 312 to the first side 311), the first honeycomb core 31 has three stages: elastic stage, plateau yield stage, densification stage. Wherein, in the stage of platform yield, the compressive strength of first honeycomb core 31 is basically at the steady value, and this mechanical properties accords with the demand of seat 100 anti-falling performance under the crash condition. In the present embodiment, after the first honeycomb core 31 is formed, the first side 311 thereof is collapsed by the preliminary compression treatment to form the compression portion 316. Specifically, as shown in fig. 6, the first honeycomb core 31 includes a honeycomb core body 315 and a compression portion 316, and the compression portion 316 is integrally formed on the honeycomb core body 315 and located on a side of the honeycomb core body 315 facing the cushion portion 11. After the first honeycomb core 31 has been pre-compressed, it has entered a platform yielding phase from the elastic phase, where the compressive strength of the first honeycomb core 31 is at a substantially steady value. The crushing peak value can appear in the impact that conventional honeycomb core received when elasticity stage, and the first honeycomb core 31 of this application embodiment is owing to through the precompression, can not appear the crushing peak value in the use, and compressive strength stability is high, has improved seat 100's security.

In the present embodiment, the first honeycomb core 31 is further provided with occupying holes 314, and the occupying holes 314 penetrate at least one of the first side 311 and the second side 312 and are located between the plurality of first honeycomb holes 313. The trap hole 314 is used for pressure relief of the first honeycomb core 31. When the first honeycomb core 31 is compressed in the normal direction (the direction from the first side 311 to the second side 312) in the crash condition, a part of the first honeycomb holes 313 at one end of the first side 311 collapses under the impact force, and the cell wall is broken, so that the air which is not exhausted before in the first honeycomb holes 313 enters the occupation hole 314 along the collapsed port of the first honeycomb holes 313, and the pressure in the first honeycomb holes 313 is relieved.

The number of the occupation holes 314 is provided in plural, and the plural occupation holes 314 are distributed among the plural first honeycomb holes 313 at intervals. The specification does not limit the specific shape of the placeholder hole 314, and in this embodiment, the placeholder hole 314 is a circular hole. If the pore diameters of the first honeycomb holes 313 are equal, the plurality of occupying holes 314 may be distributed among the first honeycomb holes 313 at intervals, and the distance between two adjacent occupying holes 314 is greater than or equal to one time the pore diameter of the first honeycomb hole 313. The occupying hole 314 has a larger pore diameter (the inner diameter of the aforementioned regular hexagon) than the largest pore diameter of the plurality of first honeycomb holes 313, wherein the pore diameter of the first honeycomb holes 313 is the inner diameter of the regular hexagon if the first honeycomb holes 313 are regular hexagonal holes, and the pore diameter of the first honeycomb holes 313 is the width of the rectangle if the first honeycomb holes 313 are rectangular holes.

In the case where the plurality of occupied spaces 314 are formed, the pore diameter of the first honeycomb holes 313 of the first honeycomb core 31 may be set smaller, and the first honeycomb core 31 may have more and densely arranged first honeycomb holes 313, so that the structural strength of the first honeycomb core 31 is enhanced.

The first honeycomb core 31 may have a difference in compressive strength at different compression rates, and typically has a dynamic compressive strength greater than the static compressive strength, which is approximately 1.5 to 2.0 times (inclusive) the static compressive strength. When the dynamic compression strength has been determined, the static compression strength is too small, and the dynamic-static ratio is large, which may cause the first honeycomb core 31 to be crushed when a passenger is seated. In the present embodiment, the first honeycomb core 31 is further decompressed by the occupying holes 314, and the structural strength is enhanced by the plurality of dense and small first honeycomb holes 313 while the dynamic-static ratio is reduced, thereby reducing the possibility that the first honeycomb core 31 is damaged when a passenger sits due to too small static compressive strength.

Referring to fig. 7, in the present embodiment, the buffer structure 30 may further include a dispersion member 32, the dispersion member 32 is disposed between the first honeycomb core 31 and the cushion portion 11 and covers one end of the first honeycomb holes 313 on the first side 311, and the dispersion member 32 is used for dispersing the impact load applied to the buffer structure 30 to various positions of the first honeycomb core 31. The dispersion member 32 has a substantially square plate shape, and the dispersion member 32 is connected to the first honeycomb core 31 by means of gluing. The specific material of the dispersion member 32 is not limited in this specification, and for example, the dispersion member 32 may be an aluminum plate or a glass fiber plate. Under the crash working condition, the dispersion member 32 can disperse the larger pressure transmitted by the cushion part 11 from one place to a plurality of places, so that the first honeycomb core 31 can absorb the impact load in a wider range, and the safety of passengers is improved. The dispersion member 32 can also increase the structural strength of the first honeycomb core 31, thereby reducing the possibility that the first honeycomb core 31 collapses to cause secondary damage to a human body when falling into an airplane, and also reducing the possibility that the first honeycomb core 31 is locally compressed and damaged when a passenger normally sits.

The specification does not limit the specific structure of the dispersion member 32, and the dispersion member 32 may be perforated or may not be perforated. In some embodiments, the hole axis direction of the placeholder holes 314 and the hole axis direction of the first honeycomb holes 313 are substantially the same, i.e., the hole axis directions of the two coincide, e.g., the hole axis directions of the two are parallel (theoretically, parallel) to each other. The occupation hole 314 penetrates through the first side 311 and the second side 312, the dispersion member 32 can be provided with a through hole communicating the occupation hole 314, and the through hole can be matched with the occupation hole 314 to complete the pressure relief of the first honeycomb core 31. In this case, the dispersion member 32 may be made of an aluminum plate to ensure rigidity. The cushion part 11 can be made of a porous material to match the through holes of the dispersion member 32 and the occupying holes 314 for pressure relief.

Referring to fig. 7 to 9, the buffering structure 30 may further include a supporting member 33, and the supporting member 33 is disposed on the second side 312 of the first honeycomb core 31. The support 33 is substantially in the form of a square plate, which is connected to the end face of the second side 312 by means of gluing. The supporting piece 33 increases the structural strength of the first honeycomb core 31, and further reduces the possibility that the first honeycomb core 31 collapses to cause secondary damage to a human body when the aircraft is crashed. The specific material of the support member 33 is not limited in this specification, and for example, the support member 33 may be an aluminum plate or a glass fiber plate. In this embodiment, the support member 33 is an aluminum plate. If the occupation hole 314 penetrates the second side 312, the supporting member 33 may be provided with a first through hole 331. The first through holes 331 communicate with the occupation hole 314 and/or the first honeycomb holes 313 (shown in fig. 6). The number of the first through holes 331 is plural, and the plural first through holes 331 are substantially equally spaced apart from each other in the supporting member 33. The aperture of the first through hole 331 is smaller than that of the seating hole 314, or the aperture of the first through hole 331 is smaller than or equal to the largest aperture of the plurality of first honeycomb holes 313. If the first through holes 331 are different in size, the largest aperture of the first through holes 331 is smaller than or equal to the largest aperture of the first honeycomb holes 313. The first through holes 331 have a smaller or equal diameter than the placeholder holes 314 and the first honeycomb holes 313, thereby facilitating the exhaust while ensuring the strength of the support 33.

Further, in order to facilitate the exhaust of the gas in the first honeycomb core 31, a plurality of second through holes 142 are opened at one side of the covering portion 14 close to the supporting member 33, and the second through holes 142 communicate the first through holes 331 and the outside of the installation space 141. The hole diameter of the occupation hole 314 is larger than that of the first through hole 331, and the hole diameter of the first through hole 331 is larger than that of the second through hole 142. The second through hole 142 is provided with a small hole diameter, which facilitates air discharge while ensuring the strength of the covering part 14. In some embodiments, the second through-hole 142 may also include one or two holes with larger hole diameters to ensure the structural strength of the cladding 14.

When the first honeycomb core 31 is pressed, one end of the first honeycomb core at the first side 311 is collapsed, and a part of air in the first cell holes 313 directly enters the installation space 141 through the first through holes 331 and then enters the outside through the second through holes 142. Part of air in the first honeycomb holes 313 enters the occupying holes 314 through the collapsed parts, and then enters the outside from the occupying holes 314 through the first through holes 331 and the second through holes 142, so that the pressure relief of the first honeycomb core 31 is completed.

The present specification does not limit whether the dispersion member 32 and the support member 33 are opened to cooperate with the occupation hole 314 for pressure relief, for example, if the occupation hole 314 penetrates through the first side 311, the dispersion member 32 may be opened, and the support member 33 does not need to be opened; if the capture holes 314 extend through the second side 312, the support member 33 may be perforated without the dispersion member 32 being perforated; if the occupation hole 314 penetrates the first side 311 and the second side 312, at least one of the dispersion member 32 and the support member 33 is opened. In this embodiment, the occupying hole 314 passes through the first side 311 and the second side 312, the supporting member 33 has a first through hole 331, and the dispersing member 32 does not have an opening.

Referring to fig. 10, in some embodiments, the cushioning structure 30 may further include a second honeycomb core 35, the second honeycomb core 35 overlying the second side 312 of the first honeycomb core 31. The structure of the second honeycomb core 35 may be substantially the same as the structure of the first honeycomb core 31, for example, the second honeycomb core 35 may be provided with a plurality of honeycomb holes which are also arranged in the same manner as the first honeycomb holes 313. The second honeycomb core 35 may be provided with a plurality of exhaust holes between the plurality of honeycomb holes, and the second honeycomb core 35 may further include a compressed portion or the like. The features of the second honeycomb core 35 corresponding to those of the first honeycomb core 31 can be referred to the above description of the first honeycomb core 31, and the description is incorporated into the present embodiment and will not be described herein again.

Specifically, in the present embodiment, the second honeycomb core 35 is provided with a plurality of second honeycomb holes having the hole axis directions substantially in the same direction as the hole axis directions of the first honeycomb holes 313, that is, the hole axis directions of the two are coincident with each other, for example, the hole axis directions of the two are parallel to each other (theoretically, parallel). The second honeycomb holes have a smaller pore diameter than the first honeycomb holes 313, and the second honeycomb core 35 has a greater strength than the first honeycomb core 31. If the first cell holes 313 are regular hexagonal holes, the above-mentioned "the second cell holes have a smaller pore size than the first cell holes 313" may be understood as the second cell holes having a smaller side length than the first cell holes 313.

Here, "smaller" may be understood as a portion of the second honeycomb holes having a smaller pore size than a portion of the first honeycomb holes 313. For example, if the pore diameters of the second honeycomb holes are different in size and the pore diameters of the first honeycomb holes 313 are the same, smaller means that the largest pore diameter of the second honeycomb holes is smaller than the pore diameter of each of the first honeycomb holes 313. If the pore sizes of the second honeycomb holes are different and the pore sizes of the first honeycomb holes 313 are different, the "smaller" indicates that the largest pore size of the second honeycomb holes is smaller than the smallest pore size of the first honeycomb holes 313. If the pore diameters of the plurality of second honeycomb holes are the same and the pore diameters of the plurality of first honeycomb holes 313 are different, the "smaller" indicates that the pore diameter of each of the second honeycomb holes is smaller than the smallest pore diameter of the plurality of first honeycomb holes 313.

The strength of the first honeycomb core 31 to the second honeycomb core 35 is increased, so that the buffer structure 30 realizes variable load energy absorption, can be suitable for passengers in a larger weight range, and improves the applicability of the seat 100.

In some embodiments, the cushioning structure 30 may further include a third honeycomb core 36, the third honeycomb core 36 overlying a side of the second honeycomb core 35 facing away from the first honeycomb core 31. The structure of the third honeycomb core 36 may be substantially the same as that of the first honeycomb core 31, for example, the third honeycomb core 36 may be provided with a plurality of honeycomb holes which are also arranged in the same manner as the first honeycomb holes 313. The third honeycomb core 36 may also be provided with a plurality of exhaust holes, the plurality of exhaust holes are located between the plurality of honeycomb holes, the third honeycomb core 36 may further include a compression portion, and the like, and the features of the third honeycomb core 36 corresponding to the features of the first honeycomb core 31 may refer to the description of the first honeycomb core 31, and the description is incorporated into this embodiment, and will not be repeated here.

Specifically, in the present embodiment, the third honeycomb core 36 is provided with a plurality of third honeycomb holes, and the hole axis directions of the third honeycomb holes are substantially the same as the hole axis directions of the first honeycomb holes 313, that is, the hole axis directions of the third honeycomb holes coincide with the hole axis directions of the first honeycomb holes 313, for example, the hole axis directions of the third honeycomb holes are parallel to each other (theoretically, parallel). The third honeycomb holes have a smaller diameter than the second honeycomb holes, and the third honeycomb core 36 has a greater strength than the second honeycomb core 35. If the honeycomb holes are regular hexagonal holes, the above-mentioned "the diameter of the third honeycomb holes is smaller than that of the second honeycomb holes" can be understood as that the side length of the third honeycomb holes is smaller than that of the second honeycomb holes.

Wherein "less than" is to be understood as a portion of the third honeycomb cells having a smaller pore size than a portion of the second honeycomb cells. For example, if the pore diameters of the third honeycomb holes are different in size and the pore diameters of the second honeycomb holes are the same, the "smaller" indicates that the largest pore diameter of the third honeycomb holes is smaller than the pore diameter of each of the second honeycomb holes. If the pore diameters of the third honeycomb holes are different in size and the pore diameters of the second honeycomb holes are different in size, the value smaller than the maximum pore diameter in the third honeycomb holes is smaller than the minimum pore diameter in the second honeycomb holes. If the pore diameters of the third honeycomb holes are the same and the pore diameters of the second honeycomb holes are different, the "smaller" indicates that the pore diameter of each third honeycomb hole is smaller than the smallest pore diameter of the second honeycomb holes.

The strength of the first honeycomb core 31, the second honeycomb core 35 and the third honeycomb core 36 is increased progressively, so that the buffer structure 30 has a wider range of variable load energy absorption, is suitable for passengers in a larger weight range, and further improves the applicability of the seat 100.

The thicknesses of the first honeycomb core 31, the second honeycomb core 35 and the third honeycomb core 36 are not limited in the present specification, and for example, the thicknesses of the first honeycomb core 31, the second honeycomb core 35 and the third honeycomb core 36 are decreased, or the thicknesses of the first honeycomb core 31 and the second honeycomb core 35 are decreased, and the thicknesses of the second honeycomb core 35 and the third honeycomb core 36 are the same. Here, the "thickness" refers to a dimension of the first honeycomb core 31, the second honeycomb core 35, and the third honeycomb core 36 in a direction from the first side 311 to the second side 312, that is, in a cell axis direction of the first cell holes 313.

In other embodiments, as shown in fig. 11, a projection of the third honeycomb core 36 along the direction from the first side 311 (shown in fig. 5) to the second side 312 (i.e., the hole axis direction) is overlapped with a projection of the second honeycomb core 35 along the direction from the first side 311 to the second side 312, and the projection area of the third honeycomb core 36 is larger than the projection area of the second honeycomb core 35. The projection of the second honeycomb core 35 along the hole axis direction covers the projection of the first honeycomb core 31 along the hole axis direction, the projection area of the second honeycomb core 35 is larger than the projection area of the first honeycomb core 31, and the strength of the first honeycomb core 31, the second honeycomb core 35 and the third honeycomb core 36 is increased progressively. The first honeycomb core 31 and the second honeycomb core 35 have a substantially rectangular block shape, and the above-mentioned "projection of the second honeycomb core 35 in the hole axis direction is overlaid on projection of the first honeycomb core 31 in the hole axis direction" can be understood as meaning that the surface area of the second honeycomb core 35 on the side facing the first honeycomb core 31 is larger than the surface area of the first honeycomb core 31 on the side facing the second honeycomb core 35. The same principle is that the projection of the third honeycomb core 36 along the direction from the first side 311 to the second side 312 is overlapped with the projection of the second honeycomb core 35 along the direction from the first side 311 to the second side 312. The incremental arrangement of the end areas of the first honeycomb core 31, the second honeycomb core 35 and the third honeycomb core 36 can also realize variable load absorption of the buffer structure 30, and improve the applicability of the seat 100.

Referring again to fig. 3, in the present embodiment, the seat 100 further includes a dive prevention structure 70. During a crash condition, the passengers in the flying device 200 have a tendency to slide forward and downward (forward and downward with respect to the passengers) due to inertia, and the safety belts are restrained, so that the waist safety belts slide into the soft tissues of the abdomen, which is called "dive". In the present embodiment, the passenger sits on the seat cushion portion 11, and the above-mentioned "lower front" position is in the installation space 141 (shown in fig. 4) and is located on the side of the cushion structure 30 away from the backrest portion 12. The present specification does not limit the specific structure and material of the anti-dive structure 70, for example, the anti-dive structure 70 may be made of a metal pipe, or may be made of EPP (expanded polypropylene) material. The EPP material is a high-crystallinity polymer/gas composite material with excellent performance, and has good compression-resistant buffering heat-insulating performance. If the dive prevention structure 70 is made of EPP material, the dive prevention structure 70 may be fixed between the cushion part 11 and the covering part 14 by means of adhesion. The anti-dive structure 70 serves to support the passenger on the one hand and to slow down the tendency of the passenger to dive forward on the other hand, thereby reducing the injury of the passenger from the seat belt.

In the seat 100 that this application embodiment provided, buffer structure 30 sets up in cushion portion 11 below, and when the crash operating mode, buffer structure 30 slows down the impact force when the passenger bears the impact, slows down the acceleration of passenger's downward motion to protect the passenger. The first honeycomb core 31 is pre-compressed after being formed, the elastic stage enters the platform yielding stage, the first honeycomb core 31 cannot generate a crushing peak value in the using process, the compression strength stability is high, and the safety of the seat 100 is improved. The first honeycomb core 31 is further decompressed by the occupying holes 314, and the structural strength is enhanced by the plurality of dense and small first honeycomb holes 313 while the dynamic-static ratio is reduced, thereby reducing the possibility that the first honeycomb core 31 is damaged when a passenger sits due to an excessively small static compressive strength. The dispersion member 32 can disperse a large pressure transmitted from the cushion part 11 from one place to many places, thereby facilitating the first honeycomb core 31 to absorb the impact load in a wider range, improving the safety of the passenger.

The strength of the first honeycomb core 31, the second honeycomb core 35 and the third honeycomb core 36 is increased gradually, so that the range of variable load energy absorption of the buffer structure 30 is wider, the buffer structure is suitable for passengers in a larger weight range, and the applicability of the seat 100 is further improved. The carbon fiber body 10 contributes to weight reduction of the seat 100 while ensuring structural strength of the seat 100. The various structures of the seat 100 are connected by gluing, which further promotes the light weight of the seat 100.
