The invention discloses an intelligent windproof bicycle trailer which comprises a compartment, a trailer seat, a backrest, wheels, a trunk and a connection rod. The connecting rod is fixed with a bicycle through a movable connecting part, an arc-shaped storing slot is arranged between the midpoint of the top end of the backrest and the midpoint of the upper end of the front wall of the compartment, the two sides of the arc-shaped storing slot are each provided with an arc-shaped support rod, windproof cloth corresponding to the arc-shaped support rods is arranged in the arc-shaped storing slot, the top end of the backrest is provided with a first guide rail, the top end of the front wall of the compartment is provided with a second guide rail, the two ends of each arc-shaped support rod are located in the first guide rail and the second guide rail respectively, and a wind velocity transducer is arranged on the compartment or the backrest. When the wind velocity detected by the wind velocity transducer is larger than a preset threshold value, the arc-shaped support rods at the two sides of the arc-shaped storing slot are moved to the two sides along the first guide rail and the second guide rail and stop at the two sides of the compartment, and then the windproof cloth covers on the compartment. The intelligent windproof bicycle trailer can be conveniently used at seaside or in seasons with strong wind, and the intelligent windproof bicycle trailer is more intelligent and humanized.
