Abstract:
A load-reducing backpack, comprising a body (1), a moving board (2), straps (3), first elastic bands (4) and a limiting band (5), wherein a horizontal fixing strip (11) is arranged on one side of the body (1); the moving board (2) is located on the side of the body (1) where the horizontal fixing strip (11) is arranged; one end of each strap (3) is connected to the moving board (2), and the other end thereof is connected to the body (1); one end of each first elastic band (4) is connected to the moving board (2), and the other end thereof is located below the moving board (2) and is connected to the body (1); the limiting band (5) is arranged between the horizontal fixing strip (11) and the body (1) and passes through the space therebetween; and one end of the limiting band (5) is connected to the moving board (2), and the other end thereof is connected to the body (1). The body (1) of the backpack can move relative to the moving board (2), and the first elastic bands (4) can achieve damping and shock-absorbing effects on the body (1), such that the vibration frequency of the body (1) of the backpack is changed, and the amplitude thereof is also reduced, thereby reducing the pressure and impact of the backpack on the shoulders in a downward moving process to achieve the aim of load reduction.
