A steering control coupling structure used in a children's wagon having a wheel assembly and a towing bar is disclosed to include a linking bracket affixed to the wheel axle of the wheel assembly, a first adapter affixed to a carriage and pivoted with the carriage to the linking bracket by a pivot device, the first adapter having a circular coupling hole and two 135° sector guide holes at two sides of the circular coupling hole, and a second adapter, which is affixed to the linking bracket around the pivot device and has a circular coupling block coupled to the circular hole of the first adapter and two 45° sector guide blocks respectively inserted into the 135° sector guide holes for forcing the second adapter to bias against the first adapter when the towing bar is biased to force the wheel assembly to change the steering direction.

An active steering transmission device of an active steering system of an automotive front wheel is mounted between a steering wheel and a steering gear and comprises a driving disk (1), a driven disk (2) and an angular transmission ratio regulating device which are disposed in a transmission device housing (8), wherein the driving disk (1) is connected with the steering wheel, the driven disk (2) is connected with an input shaft of the steering gear, and the angular transmission ratio regulating device comprises an alternating current motor (4), a lead screw (5), a nut (6), a connecting rod (9) and an idler gear (3). An output shaft of the alternating current motor (4) is connected with the lead screw (5) which is disposed in the transmission device housing (8), the idler gear (3) is connected with the nut (6) via a bearing, the nut (6) is mounted on the lead screw (5), the connecting rod (9) is arranged on the nut (6), one end of the connecting rod (9) is connected with the nut, and the other end of the connecting rod (9) is disposed in a groove (10) on the transmission device housing (8) corresponding to the lead screw (5). The active steering transmission device is simple in structure, small in mechanism size, convenient to process and low in production cost.

The invention discloses a flapping-wing air vehicle capable of hovering as well as a flight control method thereof. The flapping-wing air vehicle capable of hovering comprises a vehicle body and four single-flapping-wing mechanisms, wherein the four single-flapping-wing mechanisms are mounted on two sides of the vehicle body in a left-and right and front-and-back symmetrical manner, each single-flapping-wing mechanism comprises a swinging support, a flapping wing, an actuator, an eccentric bent rod and limit rods, the swinging supports are connected with the vehicle body through hinges, the included angle formed by each hinge shaft and the vertical direction of the plane where the vehicle body is located is a small acute angle, the flapping wings are fixedly connected with the swinging supports, the actuators are fixedly mounted on the vehicle body, every two limit rods are fixedly mounted on each swinging support, one end of each eccentric bent rod is fixedly connected with an output end of each actuator, the other end of each eccentric bent rod is bent, each bent section is inserted between every two limit rods, and rotation of output shafts of the actuators is converted into swinging of the swinging supports by the aid of eccentric rotation. The air vehicle is small in size, light in weight and capable of hovering stably during flight, the flapping wings can produce the larger lifting force and provide the enough lateral force, various maneuvering actions can be realized conveniently, flapping-wing swinging mechanisms are simple and reliable, and the actuating efficiency is high.
