Description

Technical Field

[0001] The utility model relates to the technical field of building block vehicles, in particular to a steering mechanism of an articulated building block vehicle. Background Art

[0002] At present, the steering mechanism used in articulated building block vehicles mostly uses multiple gears to transmit power to a small push rod to steer the articulated building block vehicle. This steering mechanism mainly includes a motor connected to a steering power input shaft, and the power is transmitted to the small push rod through multiple gears. The internal spiral structure of the small push rod produces a distance difference in the same distance and opposite direction to achieve articulated steering. The disadvantages of the existing steering mechanism are complex structure, poor stability, poor maneuverability and flexibility, low efficiency, lack of interest of teenagers when playing, and high cost. Summary of the invention

[0003] The purpose of the utility model is to overcome the shortcomings of the existing steering mechanism, such as complex structure, poor stability, poor maneuverability and flexibility, and low efficiency, and to invent an articulated building block vehicle steering mechanism which adopts a method of interconnecting hole arms and bolts to achieve a simple structure, stable building block vehicle steering, good flexibility, and high efficiency.

[0004] The purpose of the utility model is achieved in the following manner: the steering mechanism of the articulated building block vehicle includes: a 1X2 cross shaft, a 1x3 thin hole arm interconnected with the 1X2 cross shaft, the 1x3 thin hole arm and the 1x7 thin belt hole arm are connected by a 1×2 cross shaft with bolts, the 1x7 thin belt hole arm and the 1x3 shaft bolt are connected by a 3 / 4 smooth bolt to achieve articulated steering, the 1X7 thick hole arm is fixed on the 1x7 thin belt hole arm, the 1x3 shaft bolt connection and the 3x5 H-shaped hole frame are fixed to each other to increase stability, and it is characterized in that: the 1x3 thin hole arm and the 1x7 thin belt hole arm are connected by a 1×2 cross shaft with bolts to improve steering efficiency and flexibility, the 1X7 thick hole arm is fixed on the 1x7 thin belt hole arm, the 1x3 shaft bolt connection and the 3x5 H-shaped hole frame are fixed to each other to enhance the stability of the steering mechanism.

[0005] Compared with the current technology, the beneficial effects of the utility model are as follows: the utility model adopts a 1X2 cross shaft connected with a 1x3 thin hole arm and then connected with a 1x7 thin belt hole arm to realize articulated steering. This steering mechanism has a small turning radius and high flexibility; it improves steering efficiency and reduces costs; the 1X7 thick hole arm is fixed on the 1x7 thin belt hole arm, and the 1x3 axle bolt connection is fixed to the 3x5 H-shaped belt hole frame to enhance the stability of the steering mechanism; it increases the interest of young people in articulated building block vehicles.
