The first folded board 122 is connected to the second folded board 124, and the first folded board 122 is connected to the first side 112 or the third side 116 of the top supporting board 110, and the second folded board 124 is connected between the first folded board 122 and the bottom supporting board 130.

[0041] In some embodiments, please refer to FIG. 3. FIG. 3 is a side view of the resilient cardboard cushion according to one embodiment of the present invention. As shown in the figure, the top supporting board 110, the first folded board 122, the second folded board 124, and the bottom supporting board 130 form an M-shaped elastic structure that provides an elastic force to the top supporting board 110 relative to the bottom supporting board 130, supporting the electronic product placed above the top supporting board 110. The M-shaped elastic structure thus improves the impact resistance of the electronic product when stored in the packaging carton. The height 301 is an original height of the resilient cardboard cushion 100 in its uncompressed state when not under stress.

[0042] Please further refer to FIG. 1 and FIG. 2 again. In some embodiments, the resilient cardboard cushion 100 further includes a slidable protrusion bottom board 150 connected to the slidable supporting foot 140. The width 151 of the slidable protrusion bottom board 150 is greater than the width 141 at the connection position between the slidable supporting foot 140 and the slidable protrusion bottom board 150.

[0043] Furthermore, in some embodiments, the bottom supporting board 130 further includes a U-shaped opening 132, and the slidable supporting foot 140 and the slidable protrusion bottom board 150 are slidable in the U-shaped opening 132. In addition, the U-shaped opening 132 includes a width 131, and the slidable supporting foot 140 and the slidable protrusion bottom board 150 are folded to clamp the edges of the of the U-shaped opening 132 and slides along the width 131 of the U-shaped opening 132.

[0044] Please refer to FIG. 4. FIG. 4 is a side view from another view angle. The height 301 is the original height of the resilient cardboard cushion 100 in its uncompressed state when not under pressure. In addition, two slidable protrusion bottom boards 150 are spaced apart by a gap 402. The slidable supporting foot 140 forms an inclined support structure and the slidable protrusion bottom board 150 may slide at the bottom of the resilient cardboard cushion 100.

[0045] Please refer to FIG. 2, FIG. 4, and FIG. 5, with FIG. 5 showing a side view of the resilient cardboard cushion in a compressed state. In FIG. 2, the slidable supporting foot 140 includes a first interference edge 172, and a second included angle 202 forms between the first interference edge 172 and the second side 114 of the top supporting board 110. In addition, the first folded board 122 includes a second interference edge 174, and a third included angle 203 forms between the second interference edge 174 and the first side 112 of the top supporting board 110. Further, the second folded board 124 includes a third interference edge 176, and a fourth included angle 204 forms between the third interference edge 176 and the bottom supporting board 130. In some embodiments, the third interference edge 176 and the second interference edge 174 are symmetrically formed, and the fourth included angle 204 is approximately equal to the third included angle 203, but not limited thereto. In some embodiments, the fourth included angle 204 is equal to the third included angle 203.

[0046] In FIG. 4, when the resilient cardboard cushion 100 is not stressed, the height 301 of the resilient cardboard cushion 100 is the original height thereof, and the first interference edge 172 and the second interference edge 174 separate from each other without interfering with each other.

[0047] As shown in FIG. 5, in some embodiments, when the height of the resilient cardboard cushion 100 is compressed to the height 501, approximately half of the original height of the resilient cardboard cushion 100, the first interference edge 172 and the second interference edge 174 touch each other to slow down further compression of the resilient cardboard cushion 100. Meanwhile, the two slidable protrusion bottom boards 150 move closer to each other, with a gap 502 formed therebetween.

[0048] When the height of the resilient cardboard cushion 100 is compressed to approximately half of the original height, the first interference edge 172 may touch the third interference edge 176 to slow down further compression of the resilient cardboard cushion 100.

[0049] Please refer to FIG. 2. In some embodiments, the first included angle 201 is about 90 degrees, and the sum of the second included angle 202 and the third included angle 203 is greater than 90 degrees.

[0050] In some embodiments, the second included angle 202 is 40.7 degrees to 50 degrees, preferably 40.7 degrees to 45 degrees, and more preferably 40.7 degrees to 43 degrees.

[0051] In some embodiments, the third included angle 203 is 52 degrees to 62 degrees, preferably 57 degrees to 62 degrees, and more preferably 59 degrees to 62 degrees.

[0052] In some embodiments, the first included angle 201 is about 90 degrees, the second included angle 202 is about 40.82 degrees, and the third included angle 203 is about 61.82 degrees, but not limited thereto.

[0053] Please refer to FIG. 6. FIG. 6 is a side view of the resilient cardboard cushion in a further compressed state. As shown in the figure, when the height of the resilient cardboard cushion 100 is compressed to the height 601, approximately one-third of the original height of the resilient cardboard cushion 100, e.g. from 45 mm to 15 mm, the two slidable protrusion bottom boards 150 touch each other at a contact point 602 to prevent the resilient cardboard cushion 100 from being further compressed. Therefore, full collapse to the bottom of the resilient cardboard cushion 100 can be effectively avoided, thereby providing greater support and elasticity for electronic products and preventing damage from impact.

[0054] In some embodiments, the resilient cardboard cushion 100 further includes an opening 160, which is located at the connection area of the top supporting board 110 and the first folded board 122. In some embodiments, the opening 160 may also accommodate a protruding part of an electronic product, without departing from the spirit and scope of the disclosure.

[0055] In some embodiments, the resilient cardboard cushion 100 further includes at least one circular opening 111, which is formed in the top supporting board 110 and positioned adjacent to the fourth side 118, the second side 114, or both.

[0056] In some embodiments, the resilient cardboard cushion 100 is made of any recycled cardboard or virgin cardboard, such as corrugated cardboard, cut with a die and then folded into shape, without departing from the spirit and protection of the present invention.

[0057] Accordingly, the resilient cardboard cushion according to the present invention can effectively support electronic products stored in a packaging carton. Especially when the electronic products are transported or subjected to a drop test or an impact test, the resilient cardboard cushion can provide the required cushioning support force so as to prevent the electronic products from being damaged, thereby improving the safety of the electronic products during transportation and storage.
