The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

As shown in fig. 2 and 4, the utility model provides a light sleeper of car, including a cystosepiment 2 that adopts EPP foam foaming molding and a plurality of pre-buried fossil fragments 10 of pre-buried in cystosepiment 2. All pre-buried fossil fragments 10 all parallel arrangement each other, all pre-buried fossil fragments 10 both ends are equally divided and are provided with shrinkage cavity 7 respectively. The shrinkage cavity 7 is the through-hole that sets up at pre-buried fossil fragments 10 tip and run through 2 two surfaces of cystosepiments. The cross section of the shrinkage hole 7 is larger than the end size of the embedded keel 10, the shrinkage hole 7 is wrapped outside the end of the embedded keel 10, and allowance is provided for the molding deformation of the end position of the embedded keel 10 in the foam board 2.

In the technical scheme, the EPP is adopted to prepare the high-strength foam board as the sleeping berth board of the automobile sleeping berth, and the structure that the wood board is adopted as the sleeping berth board in the prior art is replaced. EPP cystosepiment's simple structure, light in weight, intensity is high, simple to operate is swift, and the bradyseism is effectual, can not send the noise because of human activity during the use, and use comfort is high.

In the technical scheme, the EPP and the embedded keel 10 embedded in the foam board are integrally foamed and molded, so that the molding is quick and the process steps are few. The tip of pre-buried fossil fragments 10 sets up shrinkage cavity 7, provides the surplus at the internal deformation that pre-buried fossil fragments 10 tip took place during for cystosepiment 2 foaming, and the shrinkage deformation leads to taking place the extrusion with pre-buried fossil fragments 10 tip when avoiding the cystosepiment shaping, avoids pre-buried fossil fragments 10 to cause the destruction and reduce the bulk strength of cystosepiment to the inside integrality of cystosepiment.

Among the above-mentioned technical scheme, set up pre-buried fossil fragments in cystosepiment 2, ensure the roughness and the straightness of fashioned sleeping berth originally on the one hand, on the other hand increases the intensity and the bearing capacity of sleeping berth board.

In the technical scheme, the foam 2 is made of EPP, and the EPP foam density of the foam board 2 is selected from the range of 60-90 kg per cubic meter through foam molding. The EPP foam board has the advantages of excellent shock resistance and energy absorption performance, high recovery rate after plastic deformation, good heat resistance, corrosion resistance, oil resistance and heat insulation performance, light weight and wide application in various fields. And the EPP foam board can be recycled, has low cost and can not generate white pollution.

In the technical scheme, the size of the aperture D of the shrinkage hole 7 is the product of the distance L from the center of the shrinkage hole to the geometric center of the foam board 2 and the shrinkage rate psi of the raw materials for preparing the foam board. The size of the shrinkage hole 7 is calculated according to the above-mentioned manner, the EPP shrinkage ratio thereof is a range value, generally 1.0% to 2.0%, that is, the calculated diameter D of the shrinkage hole is also a range value, the shrinkage hole is preferably selected within the range value, and is not too large or too small, which may affect the overall strength of the sleeper, and too small may not provide enough margin for the foam board forming deformation.

As shown in fig. 3 and 4, the embedded keels 10 are arranged parallel to the length direction of the foam board 2, and the side surfaces of all the embedded keels 10 close to the lying surface (the surface facing the upper part after installation, that is, the surface on which the cushion is laid) of the foam board are all in the same horizontal position. Ensure that all pre-buried fossil fragments are equal apart from the cystosepiment lying face distance, the cystosepiment thickness on 2 upper portions of pre-buried fossil fragments is equal for pre-buried fossil fragments 2 atress is even, and it is high to improve the cystosepiment intensity that EPP made, and bearing capacity is good. The laying width of the embedded keels 10 is matched with the width of the foam board 2, and the two embedded keels at the outermost sides are respectively located at the two outer edges of the foam board. The embedded keel and the foam board are integrally formed in a foaming mode. General sleeping berth width is about 80 centimetres, and length is about 2 meters, and the pre-buried fossil fragments 10 quantity of predetermineeing in cystosepiment 2 is suitable in order to adapt to cystosepiment 2 width, and the equipartition sets up a plurality of pre-buried fossil fragments on cystosepiment 2 width direction promptly, and the distance is suitable with 20-30 centimetres between two pre-buried fossil fragments, and the whole weight of increase sleeping berth board, and the interval is too big can reduce sleeping berth board intensity, and the pre-buried fossil fragments of this technical scheme's embodiment adoption has three. The length of the embedded keel is suitable for being matched with the length of the foam board, or 5-10 cm of foam board allowance is reserved at the end part of the embedded keel, the allowance is too small, the embedded keel is exposed due to molding shrinkage of the foam board, and the strength of the end part of the foam board is reduced due to too large allowance.

As shown in fig. 3, the embedded keel 10 is made of square steel or U-shaped steel, an assembling hole is preset on the embedded keel 10, and mounting holes penetrating through two surfaces of the foam board are arranged at two ends of the assembling hole.
