Blow molded roof box manufacturing method and blow molded roof box

Abstract

The invention relates to a blow molded roof box manufacturing method and a blow molded roof box. The blow molded roof box manufacturing method comprises: providing a blow molding mold; carrying out material injecting and gas blowing; forming a roof box; and forming a taking-placing port. The blow molded roof box comprises the blow molded roof box and at least a roof box door. According to the present invention, the blow molded roof box does not have the windward surface binding part, such that the structure force is strong, and the water resistance can be ensured; the buckling member for the upper cover and the lower cover is not required, such that the risk of separation or loose buckling does not exist, and the material of the roof box and the manufacturing cost can be saved; the structure force can be ensured by using the lightweight material, such that the single person can easily use and operate; and the problem that the separation between the upper cover and the lower cover during the vehicle driving causes the danger can be avoided.

Description

technical field [0001] The invention relates to a manufacturing method of a roof box and a roof box, in particular to a manufacturing method of a blow molding roof box and a blow molding roof box. Background technique [0002] As the demand for recreational use of cars increases, the demand for roof boxes continues to increase significantly. However, although the roof boxes used today are of a great variety, they are still only limited in the cool and varied appearance or the decorative changes of the shapes, and the essence of combining the upper and lower covers is still not improved. [0003] That is to say, the known roof boxes are all upper and lower covers, which are combined with multiple fasteners. There is a need to increase the thickness to ensure structural strength, and the upper and lower covers cannot be tightly combined and are easily blown apart by wind. The cover can't really combine tightly and can't really waterproof and other shortcomings. [0004] What...

Problems solved by technology

However, although the roof boxes used today are of a great variety, they are only limited to the cool and varied appearance or the decoration change of the shape. It needs the essence of combining the upper and lower covers, and there is still no improvement.

[0003] That is to say, the known roof boxes are all upper and lower covers, which are combined with multiple fasteners. There is a need to increase the thickness to ensure structural strength, the upper and lower covers cannot be tightly combined and are easily blown apart by wind, and the upper and lower The cover cannot be tightly combined and cannot be waterproof and other shortcomings

[0004] What's more, the known roof boxes are very heavy and difficult to operate by a single person. Most users or a woman can't lift them at all, let alone set them up or operate them.
