Abstract:
1. A combination structure of a cart and a bicycle, comprising: a bicycle formed by a first backbone, a handle, a front wheel and a rear wheel; the first backbone serving to secured other components of the bicycle; the handle, the front wheel and the rear wheel being combined to respective positions of the bicycle; a cart formed by a second backbone, at least one front wheel, at least one rear wheels and at least one pushing rod; the cart being extended with at least one pushing rod; wherein a user can hold the pushing rods to rotate the at least one front wheel and the rear wheel so as to drive the cart to move forwards; and a hooking member extending from the cart for hooking the handle of the bicycle; a linking shaft installed to an upper side of the rear wheel of the wheelchair; a front end of the linking shaft being movably installed to the rear end of the second backbone of the wheelchair; a rear end of the linking shaft having a locking unit; in an assembling state, the locking unit at the rear end of the linking shaft is locked to a front shaft of the bicycle so that the wheelchair can be fixed to the front shaft of the bicycle; wherein a diameter of the front wheel of the bicycle is smaller than that of the rear wheel of the bicycle; and a diameter of each rear wheel of the cart is smaller than that of the front wheel; a length of the linking shaft is designed such that when the linking shaft of the wheelchair is fixed to the front wheel of the bicycle, the front wheel of the bicycle and the rear wheel of the wheelchair are not grounded so as to reduce the friction force on the ground.
