[0043] The utility model discloses a kind of elastic pad devices 100.

[0044] The continuous fiber reinforced thermoplastic composite pre-impregnated narrow band used in the present utility model is referred to as narrow band.

[0045] The continuous fiber reinforced thermoplastic composite tape has high strength and high elasticity, can meet the requirements of various application scenarios, and is lightweight itself (compared with traditional metal materials), which is particularly important in applications requiring weight reduction. In addition, the continuous fiber composite tape also has corrosion resistance and can be used for a long time in harsh environments, showing great application potential in many fields.

[0046] The thickness of the continuous fiber reinforced thermoplastic composite tape is usually around 0.15-0.4mm, for example, it can be a 0.26mm thick continuous glass fiber reinforced polypropylene resin tape.

[0047] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings.

[0048] As shown in Figure 1 , Figure 2 The elastic pad device 100 includes at least one pad plate and a plurality of elastic units 103.

[0049] The pad plate in the figure is a first pad plate 101, which can be elastically deformed and can maintain the shape of the elastic pad device 100. The entire elastic pad device 100 can be set to a regular shape such as a cube or a cuboid, and the first pad plate 101 is correspondingly set to a square or a rectangle.

[0050] A plurality of elastic units 103 are arranged above the first pad plate 101 to form an array of elastic units 103. The elastic units 103 are cylindrical in shape, with the outer circumferential surface in contact with the first pad plate 101. The axial directions of the plurality of elastic units 103 are parallel to each other, and the elastic units 103 mainly elastically deform along the radial direction when compressed.

[0051] By setting the elastic unit 103 to be cylindrical and elastically deformed in the radial direction, the elastic unit 103 has excellent elasticity, a large internal space, light weight, and excellent air permeability.

[0052] The elastic cushion device of the embodiment can be used as an industrial cushion board or a household mattress, and has lighter weight than a steel spring cushion, and better air permeability than a latex mattress, a sponge mattress, a coconut palm mattress, and the like.

[0053] In one embodiment, as shown in Figure 1 , Figure 2 , the elastic unit 103 is wound into a cylindrical shape by a continuous fiber reinforced thermoplastic resin prepreg tape, the continuous fiber reinforced thermoplastic resin prepreg tape is wound one turn, and the turns are connected by fusion bonding at the joint, or the continuous fiber reinforced thermoplastic resin prepreg tape is wound multiple turns, which can be an integer multiple or a non-integer multiple, and the tail end of the outermost turn is connected to the adjacent turn by fusion bonding.

[0054] The elastic unit 103 can be divided into a narrow tape portion 131 and a fusion bonding portion 132, the narrow tape portion 131 is a continuous fiber reinforced thermoplastic resin prepreg tape, and the fusion bonding portion 132 is a portion of the narrow tape portion 131 that is connected by resin fusion bonding and has high connection strength and does not break. The narrow tape portion 131 can include one turn of continuous fiber reinforced thermoplastic resin prepreg tape, the two ends are butted and then connected by fusion bonding, or the narrow tape portion 131 can include multiple turns of continuous fiber reinforced thermoplastic resin prepreg tape, and the tail end of the outermost turn is connected to the adjacent turn by fusion bonding. The multiple turns of continuous fiber reinforced thermoplastic resin prepreg tape can also be glued and bonded to prevent separation and maintain the structure of the elastic unit 103.

[0055] In one embodiment, as shown in Figure 1 , Figure 3 , Figure 4 , multiple elastic units 103 are stacked one on top of another, and at least two layers are stacked, and more than two layers can be stacked according to actual needs, and the elastic units 103 of adjacent layers are arranged in a staggered manner, and the staggered distance is the radius of the elastic unit 103, and a stacking structure with the maximum density can be formed.

[0056] Because the elastic unit 103 is cylindrical, one elastic unit 103 in the upper layer is arranged between two elastic units 103 in the lower layer, thereby forming a relatively stable staggered stacking structure, and the staggered distance is the radius of the elastic unit 103.

[0057] In one embodiment, as shown in Figure 1 , Figure 3 , Figure 4As shown, the elastic units 103 in the same layer are arranged staggered between two adjacent columns of elastic units 103 along the axial direction, and the staggered distance is the radius of the elastic unit 103. Through this arrangement, the two adjacent columns of elastic units 103 in the same layer can support each other by the solid part, that is, support each other by the narrow band 131, thereby forming a relatively stable support structure to avoid quality defects such as cracking and collapse of the elastic pad device 100. Although staggered arrangement is adopted, the elastic units 103 in the same layer can still be connected in a circle to form a breathable cavity, which has excellent breathability.

[0058] In one embodiment, the elastic pad device 100 further comprises:

[0059] The plurality of elastic units 103 whose outer circumferential surfaces are in contact are bound by the binding rope, and the binding rope can cross the inner circle of the elastic unit 103 in a method similar to braiding. By binding the plurality of elastic units 103, the relative structural relationship of the array of elastic units 103 can be ensured not to change, and quality defects such as cracking and collapse of the elastic pad device 100 caused by the disengagement of a certain elastic unit 103 from the predetermined position can be avoided.

[0060] In one embodiment, as shown, Figure 5 The elastic pad device 100 comprises:

[0061] The first pad plate 101 is located below the array of elastic units 103;

[0062] The second pad plate 102 is located above the array of elastic units 103, and the plurality of elastic units 103 are arranged between the first pad plate 101 and the second pad plate 102.

[0063] The area of the second pad plate 102 can be less than or equal to the first pad plate 101, and the second pad plate 102 can be elastically deformed. By arranging the first pad plate 101 and the second pad plate 102, the shape of the elastic pad device 100 can be better maintained, and the overall elasticity and strength of the elastic pad device 100 can be improved.

[0064] In one embodiment, the uppermost elastic unit 103 is fused and bonded to the second pad plate 102, and the lowermost elastic unit 103 is fused and bonded to the first pad plate 101, that is, hot melting connection is adopted. Through this arrangement, the relative structural relationship of the array of elastic units 103 and the first pad plate 101 and the second pad plate 102 can be ensured not to change, and the array of elastic units 103 and the first pad plate 101 and the second pad plate 102 can be prevented from disengaging from the predetermined position. The shape of the elastic pad device 100 can be better maintained, the overall elasticity and strength of the elastic pad device 100 can be improved, and quality defects can be avoided.

[0065] In one embodiment, the first pad plate 101 and the second pad plate 102 are made of a plurality of layers of continuous fiber reinforced thermoplastic resin pre-impregnated sheets, which are hot-melt connected or glued together, and have the same material and elasticity as the elastic unit 103, and have excellent elasticity and light weight.

[0066] In one embodiment, as shown in Figure 6 , the elastic pad device 100 further comprises:

[0067] a cover 105, which wraps at least one pad plate and a plurality of elastic units 103, if the elastic pad device 100 only has the first pad plate 101 and the plurality of elastic units 103, the cover 105 wraps the first pad plate 101 and the plurality of elastic units 103, if the elastic pad device 100 has the first pad plate 101, the second pad plate 102 and the plurality of elastic units 103, the cover 105 wraps the first pad plate 101, the second pad plate 102 and the plurality of elastic units 103.

[0068] The cover 105 isolates the pad plate and the plurality of elastic units 103 from the outside world, which can prevent foreign matter from entering the array of elastic units 103, and can also prevent external objects from damaging the pad plate and the plurality of elastic units 103, thereby ensuring the quality of the elastic pad device 100. The cover 105 can be made of fabric material, such as fabric material suitable for industrial use or fabric material suitable for home use.

[0069] In one embodiment, as shown in Figure 1 , Figure 6 , the elastic pad device 100 further comprises:

[0070] a pull rope 104, which connects the upper surface and the lower surface of the cover 105, and passes through the gap between the two rows of elastic units 103 adjacent along the axial direction and the pad plate, and the pad plate is provided with a threading hole corresponding to the pull rope 104. By connecting the upper surface and the lower surface of the cover 105 through the pull rope 104, the surface of the cover 105 can be attached to the pad plate and the array of elastic units 103, thereby avoiding quality defects such as bulging and skewing of the cover 105.

[0071] The elastic pad device according to the present application has the following advantages:

[0072] It can be used as an industrial cushion pad or a household mattress. Compared with a steel spring pad, the present application has lighter weight, and compared with a latex mattress, a sponge mattress and a coconut palm mattress, the present application has better air permeability.
