[0065] The present application is further described in detail below in conjunction with the accompanying drawings.

[0066] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of this application. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items. Embodiment 1

[0068] Figure 1 A multi-layer three-dimensional fabric suspended core structure is shown, including multiple truss units superimposed and connected to each other. It is defined that a truss is a structure similar to an arch in the design of a bridge in the field of architecture. In this embodiment, each truss unit includes a truss layer 10, and the truss layer 10 includes a plurality of adjacently arranged support parts 11. The cross section of the support part 11 can be arch-like, or it can be a trapezoid, a triangle, or multiple deformations. There is a peak 111 at the highest point and a trough 112 at the lowest point between two adjacent support parts 11. The peak 111 structure here can be a point-like cross section or a plurality of line cross sections connected to the same highest point. Similarly, the definition of the trough 112 is the same as that of the peak 111. In this embodiment, the support part 11 takes an arch-like cross section as an example, and the peak 111 and the trough 112 are both point-like cross sections. There is a spacing between the two adjacent peaks 111 and the two troughs 112 to form a truss space 12. The truss space 12 provides the support part 11 with a certain elastic deformation ability when subjected to external forces, and at the same time has a certain elastic recovery ability.

[0069] Combination Figure 2 The truss layer 10 is a woven structure formed by weaving a plurality of warps and wefts, and a plurality of air holes are provided between the warps and wefts to provide better air permeability. In addition, the warps and / or wefts are made of germanium fiber wires, which are made by mixing germanium elements into traditional fiber materials.

[0070] Shared Reference Figure 3 and Figure 4, multiple truss layers 10 are superimposed and connected to each other. In this embodiment, the support parts 11 of two upper and lower adjacent truss layers 10 are symmetrically connected to each other. Of course, two upper and lower adjacent truss layers 10 can also be parallel and overlapped with each other. In the former combined connection structure of truss units, the upper and lower support parts 11 symmetrically conflict with each other, so that the entire suspension core structure has a higher elastic deformation capacity; while in the latter combined connection structure of truss units, the elastic stiffness of the entire suspension core structure is increased and has a higher weighing capacity.

[0071] In this embodiment, the entire suspended core structure also includes a plurality of flexible members 30, and the flexible members 30 further fix each truss unit. After the two supporting parts 11 of the upper and lower truss layers 10 are connected by hot-melt process, the two ends of the flexible member 30 penetrate each truss layer 10 to achieve further fixation. In this embodiment, the flexible member 30 includes a fixed end 31 and two free ends 32, and the two free ends 32 penetrate each truss layer 10 to achieve connection. The fixed end 31 is fixed to the truss unit of one outer layer, and the two free ends 32 are connected and fixed to the truss unit of the other outer layer. The flexible member 30 is a flexible rope, and the entire flexible member 30 is penetrated and connected with each truss layer 10 by sewing equipment or manually. Embodiment 2

[0072] Figure 5 The structure of another truss unit is shown, which is different from the first embodiment in that it further includes a supporting layer 20 , and the truss layer 10 is connected to the supporting layer 20 .

[0073] Combination Figure 6 The truss layer 10 and / or the support layer 20 are a woven structure formed by weaving a plurality of warp threads and weft threads. In the present embodiment, the truss layer 10 is a woven structure in which the warp and weft threads are interwoven, and the support layer 20 is formed by arranging a plurality of warp threads. The plurality of support portions 11 of the truss layer 10 are connected to the support layer 20 by a hot melt process, and a hot melt woven connection portion 13 is formed at the connection between the two.

[0074] See also Figure 7 In another embodiment, the support layer 20 adopts a woven structure of warp and weft that is the same as the truss layer 10. The warp and / or weft of the support layer 20 are germanium fiber lines.

[0075] In this embodiment, when the upper and lower truss units are superimposed and connected, the truss layer 10 and the support layer 20 are arranged and connected in sequence, and at the same time, the two adjacent truss layers 10 can be arranged in parallel or staggered in the length direction. In the parallel arrangement state, the crests 111 and troughs 112 of the two supports are in the same vertical plane. In the staggered arrangement state, the crests 111 and troughs 112 of the two supports are not in the same vertical plane. The two states can select structures with different elastic stiffness according to user needs. Embodiment 3

[0076] Figure 8 Another structure of a truss unit is shown, which differs from the second embodiment in that a truss layer 10 is added, and the two truss layers 10 are symmetrical and connected.

[0077] In this embodiment, the upper and lower truss units are superimposed and connected in the same manner as in the second embodiment, the truss layer 10 is connected to the support layer 20, and the truss layer 10 between the two truss units also has two forms: parallel arrangement and staggered arrangement. Fig. 9 The structure in which the truss layers 10 in the two truss units are arranged in parallel is shown. Embodiment 4

[0078] Fig.10 Another structure of a truss unit is shown, which differs from the third embodiment in that two truss layers 10 are distributed and connected on both sides of the supporting layer 20 .

[0079] See also Fig.11 The two truss layers 10 are staggered in the length direction, and the two truss layers 10 can also be symmetrically arranged. In a single truss unit, the staggered arrangement makes the hot-melt woven connection part 13 on the support layer 20 denser, and the distance between two adjacent support parts 11 is defined as L. The elastic stiffness of the truss unit can be achieved by adjusting the distance L.

[0080] Fig.12 and Fig.13 The connection forms between the two truss units when the two truss layers 10 are staggered and symmetrically arranged in a single truss unit are shown respectively. The staggered arrangement of the two truss layers 10 in a single truss unit corresponds to two superposition states, namely, the two truss layers 10 in the upper and lower truss units are arranged in parallel or staggered. Embodiment 5

[0081] Fig.14 Another truss unit structure is shown, which differs from the fourth embodiment in that an additional truss layer 10 and a support layer 20 are added, and three truss layers 10 are sequentially connected with two support layers 20. In each truss unit, the upper and lower truss layers 10 have the same staggered arrangement and symmetrical arrangement as the fourth embodiment.

[0082] Fig.15 The diagram shows the upper and lower truss layers 10 in a staggered arrangement state.

[0083] Fig.16 and Fig.17 The upper and lower truss layers 10 in a single truss unit are shown to be connected in a parallel arrangement and in a stacked arrangement in a symmetrical arrangement. Embodiment 6
