Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned vehicles, and particularly relates to a side deck structure of an unmanned vehicle. Background Art

[0002] With the development of unmanned platforms, the variety of thin-walled armored steel hulls is increasing, but the strength and lightweight requirements for their side decks are becoming increasingly stringent. However, strength and lightweight are contradictory. Currently, most side decks are reinforced by increasing thickness to address strength issues, resulting in increased weight. While using titanium alloys to increase strength can achieve lightweighting requirements, it also increases production costs. Summary of the Invention

[0003] In order to solve the above technical problems, the utility model provides an unmanned vehicle side deck structure with high rigidity, strength and anti-ballistic performance, light weight and low production cost.

[0004] The technical solution adopted in this utility model is:

[0005] A side deck structure for an unmanned vehicle comprises an upper side deck, a lower side deck and a horizontal deck. The lower end of the upper side deck is welded to one end of the horizontal deck, and the other end of the horizontal deck is welded to the upper end of the lower side deck. The upper side deck and the lower side deck are arranged in parallel, and the middle part of the horizontal deck is perpendicular to the upper side deck.

[0006] Furthermore, the upper and lower side decks are armored steel plates, and the horizontal decks are ordinary steel plates.

[0007] Furthermore, the thickness of the upper side deck, the lower side deck and the horizontal deck is 1~4mm.

[0008] Furthermore, both ends of the horizontal deck are bent, and the bending radius is R2~R5mm; the bent parts at both ends of the horizontal deck are lap-welded to the side upper deck and the side lower deck respectively.

[0009] Furthermore, the overlap distance is 10-40 mm; and the weld leg height is 2-5 mm.

[0010] Furthermore, the middle portion of the horizontal deck is perpendicular to the bent portion.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model uses armored steel plates + ordinary steel plates to overlap and weld the side deck to form a "Z"-shaped structure. Compared with conventional side decks, it not only ensures the strength, rigidity and anti-bullet performance of the unmanned vehicle side deck, but also reduces the weight of the unmanned vehicle side deck. At the same time, the horizontal deck uses ordinary steel plates, which reduces the economic cost of the unmanned vehicle side deck. BRIEF DESCRIPTION OF THE DRAWINGS
