The existing personal bulletproof equipment has the disadvantages such as a simple structure, insufficient folding and lack of an automatic opening function, and is thus not suitable for one-handed operations in a narrow and small space inside a vehicle. A foldable bulletproof shield disclosed in the present invention comprises a shield plate, a handle, an unfolding power device and an unfolding control device. The folding of the shield plate is realized by means of its own deformation. The unfolding power device is an elastic force device or an elastic structure provided in the foldable shield plate. The unfolding control device is composed of a button, a buckle, a strap, etc. and is integrated with the handle, such that a user enables the bulletproof shield to rapidly switch from a folded state to an unfolded state with one-handed operations.
