Abstract
一种重力势能驱动自动避障小车，属于自动避障小车转向系统的设计领域，其主要特征在于转向机构的两个凸轮呈180°对称分布，并始终与侧轮保持接触，传动轮固定在凸轮轴上，由后轮轴驱动；还包括能量转换装置，重块的重力势能为整车提供能量。本实用新型的优点在于提供一种转向平稳、结构简单、能量利用率高、成本低、节能环保的重力势能驱动自动避障小车。
An automatic obstacle avoidance car driven by gravity potential energy, which belongs to the design field of steering system of automatic obstacle avoidance car. Its main feature is that the two cams of the steering mechanism are symmetrically distributed at 180° and always keep in contact with the side wheels, and the transmission wheel is fixed on the cam. On the shaft, it is driven by the rear wheel shaft; it also includes an energy conversion device, and the gravitational potential energy of the weight provides energy for the whole vehicle. The utility model has the advantages of providing a gravitational potential energy-driven automatic obstacle avoidance car with stable steering, simple structure, high energy utilization rate, low cost, energy saving and environmental protection.
Description
Technical field
The utility model is mainly concerned with automatic obstacle-avoiding dolly steering system design field, specifically is a kind of dolly of turning to automatically realized by cam.
Background technology
The automatic carriage with direction control function that a kind of gravitional force drives is consistent with nationwide competition, for the carbon-free dolly of three-wheel that gravitional force drives is kept away the barrier walking.Require a given gravitional force, dolly can be converted into mechanical energy, as the driving force that moves ahead.The barrier that this automatic carriage can be avoided being provided with on the racing track when moving ahead automatically (the elastic barrier pole of diameter 20mm, a high 200mm is placed at 1 meter at every interval).
Summary of the invention
The utility model be to provide a kind of turn to steady, simple in structure, capacity usage ratio is high, cost is low, the gravitional force of energy-conserving and environment-protective drives the automatic obstacle-avoiding dolly.Realize by following content:
A kind of gravitional force drives the automatic obstacle-avoiding dolly, comprise front-wheel, trailing wheel, vehicle frame, gearing and steering mechanism, steering mechanism is 180 ° of symmetrical distributions by two cams, two side wheels that radius is identical are equipped with by front axle in the front-wheel both sides, and cam keeps in touch with side wheel all the time, and power wheel is fixed on the camshaft, link to each other with hind axle by belt, hind axle rotates, and drives camshaft and rotates, thereby realize that dolly turns to automatically; Also comprise energy conversion device, the gravitional force of pouring weight provides energy for car load.Pouring weight links to each other with hind axle by line, and pouring weight falls to driving hind axle and rotates, and moves ahead thereby drive dolly.
Compare with other scheme, major advantage of the present utility model is:
1, adopt pouring weight to fall and directly drive the mode that hind axle rotates, structures such as the mechanical drive system in the middle of having saved, speed change system, thus make capacity usage ratio improve;
2, adopt cam to realize the mode that turns to, relatively alternate manner has saved devices such as neutral gear transmission, makes that system's control is simple and reliable;
3, adopt cam to realize the mode that turns to, the core component cam can obtain by the line cutting with organic glass, makes integral vehicle cost reduce;
4, adopt cam to realize the mode that turns to,, make dolly turn to steadily because two cams are 180 ° of symmetrical distributions.
Description of drawings
Fig. 1 is that gravitional force drives automatic obstacle-avoiding dolly steering primary structure synoptic diagram;
Fig. 2 is that gravitional force drives automatic obstacle-avoiding dolly steering upward view.
Embodiment
Fig. 1: 1, cam; 2, front-wheel; 3, side wheel.
Fig. 2: 1, cam; 2, camshaft; 3, front axle; 4, side wheel; 5, front-wheel; 6, side wheel; 7, power wheel; 8, cam.
With reference to Fig. 1 is a kind of embodiment that a kind of gravitional force described in the utility model drives automatic obstacle-avoiding dolly steering, and the position distribution of cam 1 and side wheel 3 makes a cam then be 180 ° of symmetrical distributions with cam 1 when being the dolly straight-line travelling among the figure;
With reference to Fig. 2 is that a kind of gravitional force described in the utility model is when driving automatic obstacle-avoiding dolly straight-line travelling, the upward view of steering embodiment, cam 1, cam 8 and power wheel 7 are fixed on the camshaft 2, and side wheel 4, side wheel 6 and front-wheel 5 are fixed on the front axle 3.When power wheel 7 rotates, driving camshaft 2 rotates, cam 1 contacts with side wheel 6 with side wheel 4 with different radiuses respectively with cam 8, when the contact radius of cam 1 during greater than the contact radius of cam 8, dolly is turned right, when the contact radius of cam 8 during greater than the contact radius of cam 1, dolly turns left, left-hand rotation, the right-hand rotation in dolly cycle in moving ahead, thus realize turning to avoiding obstacles automatically.
Claims (2)
1. a gravitional force drives the automatic obstacle-avoiding dolly, comprises front-wheel, trailing wheel, vehicle frame, gearing and steering mechanism, and it is characterized in that: steering mechanism is 180 ° of symmetrical distributions by two cams, and cam keeps in touch with side wheel all the time; Also comprise energy conversion device, the gravitional force of pouring weight provides energy for car load.
2. a kind of gravitional force according to claim 1 drives the automatic obstacle-avoiding dolly, and it is characterized in that: the front-wheel both sides have increased by two side wheels.
