Furthermore, the term such as “comprising”, “having” or any variation thereof is intended to encompass non-exclusive inclusion. For example, a process, method, system, product, or device including a series of steps or units is not limited to the listed steps or units, but may further include steps or units not listed, or Preferably further includes other steps or units inherent to such a process, method, product, or device.
References to “embodiment” herein mean that a particular feature, result, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. This term existing at various positions in the specification does not necessarily refer to the same embodiment, and is not an independent or alternative embodiment that is mutually exclusive from other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.
Referring to FIG. 1, FIG. 1 is a schematic diagram illustrating the structure of a bulletproof backpack. As shown in FIG. 1, the bulletproof backpack comprises: a backpack body 10, a double-shoulder strap 11, a horizontal warning strip 13, a vertical warning strip 14, and a sandwich structure 12;
wherein the horizontal warning strip 13 is horizontally provided on the front side of the backpack body 10, the vertical warning strip 14 is arranged on a side of the backpack body 10, the sandwich structure 12 is provided on the rear side of the backpack body 10, and a plurality of layers of bulletproof fiber cloths are fixedly provided in the sandwich structure 12.
The horizontal warning strip and the vertical warning strip described above may specifically be a fluorescent strip separately.
According to the embodiment of the present application, a sandwich structure is provided at the bottom of the backpack, and a plurality of layers of bulletproof fiber cloths are provided in the sandwich structure so as to have the function of bulletproof. Moreover, the horizontal warning strip and the vertical warning strip are provided so as to prompt other people at 360° at night, such as a vehicle prompt so that it has the advantage of high security.
Preferably, the above bulletproof fiber cloth comprises, but is not limited to, a graphene fiber cloth or an aramid fiber fabric. Of course, in practical applications, the bulletproof fiber cloth provided by the present application may also be of other materials, and the present application does not limit the above bulletproof fiber cloth.
Preferably, the above bulletproof backpack may further comprise: a warning light 21.
Preferably, the above bulletproof backpack may further comprise: a GPS positioning device 22.
Preferably, each layer of the plurality of layers of bulletproof fiber cloths consists of a plurality of diamond-shaped reinforcing units 30, wherein an included angle is formed between two neighboring diamond-shaped reinforcing units of the adjacent bulletproof fiber cloths.
The plurality of diamond-shaped reinforcing units are provided to improve the bulletproof performance of the bulletproof fiber cloth. As shown in FIG. 2, the bulletproof fiber cloth may comprise a plurality of diamond-shaped reinforcing units. The diamond-shaped reinforcing units are provided to effectively relieve the impact of the bullet, especially to better relieve the rotary impact of the bullet, but the disadvantage is: for the edge position (i.e., four sides) of the diamond-shaped reinforcing unit 30, the structure is relatively weak. In order to solve this problem, the inventor has shifted the plurality of layers of bulletproof fibers by an angle, accordingly no matter what position the bullet hits, there are more diamond-shaped reinforcing units to weaken the impact of the bullet so that the entire bulletproof fiber cloth relieves the impact of the bullet and the bulletproof effect is improved.
Preferably, referring to FIG. 3, the above diamond-shaped reinforcing unit has an angle of a diamond shape of 60°, 120°, 60°, 120°, and an angle of 30° is formed between the diamond-shaped reinforcing units between the adjacent layers.
With this configuration, each diamond-shaped side line may be located in the center of the diamond-shaped reinforcing block of the adjacent layers. The center position can effectively improve the bulletproof ability of the diamond-shaped reinforcing block, which can achieve the level of a bulletproof for 9 mm gun. That is, the bulletproof level can be Level I, Level II A, or Level II, which is effectively bulletproof.
In the above embodiments, the various embodiments are described in different focuses, and the parts that are not detailed in a certain embodiment may refer to the related descriptions of other embodiments.
