Leading load acting-saving exoskeleton foot device

The invention discloses a leading load acting-saving exoskeleton foot device which is composed of an arc-shaped leading shank exoskeleton shield (1), a front sole portion foot sleeve (2) and a flexible middle rear portion foot sleeve (4). A rigid connecting piece (3) is welded to the lateral side of the front sole portion foot sleeve (2). The arc-shaped leading shank exoskeleton shield (1) is hinged to the rigid connecting piece (3) and used for protecting the shank exoskeleton. The rear end of the front sole portion foot sleeve (2) is connected with the flexible middle rear portion foot sleeve (4), and the front sole portion foot sleeve (2) and the flexible middle rear portion foot sleeve (4) are combined and used for covering a sole. The leading load of the exoskeleton is achieved by changing the connecting position of the arc-shaped leading shank exoskeleton shield (1) and the front sole portion foot sleeve (2), a front sole containing position is connected with the ground, and the acting-saving and load reduction functions of the exoskeleton foot device are further improved.
