As shown in
As an optional mode of execution, the lengths of segments, intercepted by every two adjacent vertical folding lines 11, of straight lines parallel to the transverse center line of the shading board body 1 are equal. Through the design, after the shading board body 1 is completely folded along the vertical folding lines 11, all the folding units are overlapped together in the width direction, so that the completely folded shading board body 1 is regular and attractive in appearance.
As an optional mode of execution, the folding directions of every two adjacent vertical folding lines 11 are opposite. If the folding directions of every two adjacent vertical folding lines 11 are the same, the widths of the folding units located on the outer layers need to be wider and wider to guarantee that the folded shading board body 1 is regular and smooth, thus the width of each folding unit needs to be calculated in addition, but when the folding directions of every two adjacent vertical folding lines 11 are set to be opposite, the distances between every two adjacent vertical folding lines 11 can be set to be equal, and the operation is simple and easy.
As an optional mode of execution, along the direction from the first end of the transverse direction of the shading board body 1 to the second end of the transverse direction of the shading board body 1, in every two adjacent folding units, the distance between two transverse folding lines 12 of the folding unit closer to the second end is greater than that between two transverse folding lines 12 of the folding unit closer to the first end. When the shading board body 1 is folded completely, the folding units mostly close to the first end is located at the innermost position, thus the distance between the two transverse folding lines 12 in the folding unit mostly close to the first end is set to be minimum, however, the distance between the two transverse folding lines 12 inside the folding unit mostly close to the second end is larger, so that in order to take the thickness of the shading board body 1 after multilayer folding into account, the folding unit mostly close to the second end is located at the outermost position when the shading board body 1 is completely folded, and the distance between the two transverse folding lines 12 inside the folding unit is the maximum.
As an optional mode of execution, the distance between the two transverse folding lines 12 of the folding unit mostly close to the first end is equal to the thickness of the shading board body 1. When the shading board body 1 is folded completely, the folding unit mostly close to the first end is located at the innermost position, thus the distance between the two transverse folding lines 12 of the folding unit mostly close to the first end is the minimum, the folded shading board body 1 can be compressed and deformed appropriately, and in order to accommodate deformation generated by two shading board bodies 1 after folding, the distance between the two transverse folding lines 12 is set to be the thickness of the shading board body 1.
As an optional mode of execution, along the direction from the first end to the second end, the distance between two transverse folding lines 12 of the folding unit is increased in an arithmetic progression manner. Along the direction from the first end to the second end, the thickness of two shading board bodies 1 can be increased when one transversely folded folding unit is added, thus the distance between the two transverse folding lines 12 of the folding unit is increased by a certain interval when one folding unit is added so that the thickness of the added two shading board bodies 1 is accommodated, so that the distance between two transverse folding lines 12 of the folding unit is increased in the arithmetic progression manner along the direction from the first end to the second end.
As an optional mode of execution, the tolerance of the arithmetic progression is the thickness of the shading board body 1. The thickness of two shading board bodies 1 is increased when one transversely folded folding unit is added, in consideration of that the material of the shading board body 1 can be partially compressed, thus, the thickness of one shading board body 1 is increased at the interval between two transverse folding lines 12 of the folding unit when one folding unit is added.
As an optional mode of execution, the fixed part is a fastener 2, the fastener 2 is detachably connected with the shading board body 1, the fastener 2 comprises a fastener 2 body, inserters 22 connected with the upper edge of the fastener body 21 and a snap closure 23 connected with the upper surface of the fastener body 21, inserter holes 13 and a snap closure 23 hole 14 corresponding to the inserters 22 and the snap closure 23 are formed in the shading board body 1, and the fastener 2 is connected with the shading board body 1 through the inserter holes 13 and the snap closure 23 hole 14. The fixed part can be a rubber band, an elastic cord or a magic tape, in the embodiment, the detachable fastener 21 is used as the fixed part, so that the fastener 2 can be detached when the foldable sunshade is used, the placement of the shading board body 1 on the windshield of an automobile is not influenced, after the shading board is used completely, the shading board body 1 needs to be folded and stored, and the fastener 2 is connected with the shading board body 1 again for use. After the inserters 22 connected to the upper edge of the fastener body 21 are inserted into the inserter holes 13 in the shading board body 1, protrusions on the inserters 22 can prevent the inserters 22 from being taken off from the inserter holes 13, so that the connection between the fastener 2 and the shading board body is firmer.
As an optional mode of execution, the fastener 2 is mounted at one end of the folding unit close to the second end, and the fastener 2 is located on the outer surface of the folding body after the shading board body 1 is completely folded. The fastener 2 is mounted at one end of the folding unit of which the distance between two transverse folding lines 2 is the maximum, and the fastener 2 is located on the outer surface of the folding body, so that, after the shading board body 1 is completely folded, the fastener 2 can be buckled with the folding body of the shading board body 1, and the folding body of the shading board body 1 is unlikely to scatter.
As shown in
As an optional mode of execution, the shading board body 1 is in the shape of a rounded rectangle. The shading board body 1 can be preferably adhered to the front windshield and the rear windshield of the automobile through the appearance of the rounded rectangle.
