The invention relates to the technical field of schoolbags, and discloses a portable schoolbag for study travel, which comprises a schoolbag, the back of the schoolbag is fixedly provided with an interlayer, the outer wall of the interlayer is provided with an interlayer, and the outer wall of the interlayer is provided with a cushion layer; and fixing cylinders are arranged on the two sides of the interior of the interlayer, pistons are movably arranged on the inner walls of the fixing cylinders, springs are fixedly connected between the bottoms of the pistons and the inner bottom walls of the fixing cylinders, and straps are fixedly installed on the tops of the pistons. When a human body walks, the schoolbag has a transient suspension state in foot alternation, when the schoolbag is in the suspension state, the springs recover deformation and pull the pistons to move downwards, the pistons move downwards to enable air below the pistons to be inflated into the main air bags through the air pipes, and the main air bags are inflated to swell and softly attached to the back of the human body, therefore, the function of massaging the back can be achieved, meanwhile, when the main air bag makes contact with the back, the contact area is smaller, and the back is not prone to sweating.
