[0021] The present utility model will be further described in detail below in conjunction with the accompanying drawings.
[0022] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.
[0023] As shown in the figure, a high-strength and lightweight automotive tent reclining board includes a reclining board body 1. The reclining board body 1 includes a honeycomb board layer 101. On both side surfaces of the honeycomb board layer 101, first reinforcing fiber layers 102 are respectively provided. A second reinforcing fiber layer 103 is provided to cover its peripheral side. On the outer surfaces of the first reinforcing fiber layer 102 and the second reinforcing fiber layer 103, a shell 104 is formed by spraying low-density polyurethane and hot pressing (the forming process of rigid polyurethane foam is an existing technology and will not be elaborated in this embodiment). On both sides of the lower surface of the reclining board body 1, two parallel installation beams 2 are further provided. The installation beams 2 are specifically made of aluminum for fixing and installing it on the vehicle roof.
[0024] The honeycomb board layer 101 can adopt an aluminum honeycomb board or a paper honeycomb board. By providing a shell 104 formed by polyurethane on both of its side surfaces, the overall weight of the reclining board body 1 is greatly reduced. Through the first reinforcing fiber layer 102, the structural strength of the reclining board body 1 is effectively improved, ensuring its service performance. By covering and providing the second reinforcing fiber layer 103 on the peripheral side of the honeycomb board layer 101, the structural strength at its edge is further improved, preventing the edge from cracking during use, and enhancing its service life. It has the advantages of being lightweight, high in strength, and good in heat insulation and heat preservation.
[0025] The first reinforcing fiber layer 102 and the second reinforcing fiber layer 103 include continuous glass fibers and glass fiber surface mats provided on the surfaces of the continuous glass fibers. During hot pressing, by spraying low-density polyurethane on the surface of the first reinforcing fiber layer 102, the first reinforcing fiber layer 102, the second reinforcing fiber layer 103 and the polyurethane are fully contacted and adhered, and the shell 104 is formed by hot pressing, thereby ensuring the overall structural strength after hot pressing.
[0026] The second reinforcing fiber layer 103 is adhesively bonded to the side edges and the edges of the upper and lower surfaces of the honeycomb board layer 101. During production and processing, after selecting a honeycomb board of corresponding material, the second reinforcing fiber layer 103 is covered and adhesively bonded to its peripheral side, thereby being able to ensure the structural strength of the periphery of the reclining board and effectively preventing edge cracking.
[0027] The surface of the honeycomb panel layer 101 is provided with a limiting groove 1011 for the installation beam 2 to be embedded. The two side surfaces of the installation beam 2 are provided with abutting strips 201, and the abutting strips 201 abut against the surfaces of the reinforcing fiber layers located on both sides of the limiting groove. A plurality of through holes 2011 penetrating through the upper and lower surfaces thereof are uniformly formed in the abutting strip 201 along its length direction.
[0028] After the first reinforcing fiber layers 102 are laid on both side surfaces of the honeycomb panel layer 101, the two installation beams 2 are placed into the limiting grooves 1011, so that the installation beams 2 abut against the surfaces of the first reinforcing fiber layers 102, and the abutting strips 201 are located inside the shell formed by the polyurethane, and part of the polyurethane flows into the through holes 2011, thereby ensuring the stability of the installation beam 2 after installation.
[0029] A plurality of metal embedded parts 3 are further arranged in the shell 104. During processing, the metal embedded parts 3 are placed on the surface of the first reinforcing fiber layer 102 at the required positions, so that they are located inside the shell 104 formed by the polyurethane. The metal embedded parts 3 are provided with screw holes, so that it is not necessary to drill holes in the lying board, which is convenient for the later assembly of the tent.
[0030] The specific embodiments are only explanations of the present invention, and they are not limitations on the present invention. Those skilled in the art can make modifications without creative contributions to the embodiments according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
