A device for precisely adjusting the starting direction of a walking trolley driven by gravitational potential energy

Abstract

The invention provides a device for accurately regulating the running and starting directions of a gravitational-potential-energy-driven walking trolley. The device is mounted at the front end of a bottom board of the trolley, and comprises a steering wheel, a steering wheel axle, a steering gear, a middle duplex gear, a middle wheel axle, an adjusting gear, a pointer and an angle scale, wherein the steering gear is fixed to the steering wheel axle, the adjusting gear is rotatably connected with an adjusting gear axle, the steering gear is meshed with a pinion of the middle duplex gear, a rack wheel of the middle duplex gear is meshed with the adjusting gear, the steering wheel is fixed to the steering wheel axle, the axis of the steering wheel is vertical to the axis of the steering wheel axle, the pointer is fixed to the adjusting gear along the radial direction of the adjusting gear, the angle scale is fixed to the adjusting gear axle, and the angle scale and the adjusting gear axle are concentric. The regulation precision of the device is only relevant to the transmission ratio of a gear set, when the running direction of the trolley is adjusted, only the adjusting gear needs to be stirred, the adjusting angle is directly read from the angle scale, and the operation is simple, convenient and rapid.

Description

technical field [0001] The invention relates to an adjusting device, in particular to a device for accurately adjusting the starting direction of a traveling trolley driven by gravitational potential energy. Background technique [0002] The gravitational potential energy driven walking trolley is a device that converts the gravitational potential energy into mechanical energy to drive the trolley to walk. The trolley has a three-wheel structure, one of which is a steering wheel, and the other two are traveling wheels. The energy required for the trolley to travel comes from the given gravitational potential energy. According to the rules, the score is evaluated by the distance traveled by the car and the number of obstacles bypassed. [0003] Due to the limitation of the track settings, the closer the actual orientation of the steering wheels of the car to the ideal orientation when starting, the better; otherwise, the car will quickly go out of bounds or hit obstacles.

Problems solved by technology

However, since the car needs to be disassembled and assembled once within the specified time during the competition, the steering wheel that has been calibrated before the game will deviate from the axis of the car itself due to various reasons, and the race track cannot guarantee the level. Guarantee the starting direction of the car. At present, in addition to using various starting blocks to initially determine the starting direction of the car at all levels of competition, most of them use artificial visual inspection methods to predict the starting direction of the car, which brings many accidents and uncertainties. Even if a small car with high precision in the design and manufacture of all parts, its running performance is often very unstable due to the influence of secondary disassembly and assembly and the track is not level.
