AGV with obstacle crossing function

Abstract

The invention discloses an AGV with an obstacle crossing function. The AGV comprises a vehicle body base, a driving assembly and at least two universal wheels. The driving assembly comprises a driving motor and a driving wheel. The driving motor drives the driving wheel to rotate. The driving wheel and the driving motor are installed on the vehicle body base. The vehicle body base is provided with two hinge fulcrums. Any one hinge fulcrum is movably connected with the driving wheel through a rocker arm. The other end of the rocker arm and the other hinge fulcrum are connected through a tension spring. The at least two universal wheels are installed on the front portion and the rear portion of the vehicle body base correspondingly. The driving wheel and the universal wheels support the whole vehicle body. The AGV is simple in structure and low in cost and has the very good obstacle crossing function.

Description

technical field [0001] The invention relates to the technical field of transportation equipment, in particular to an AGV trolley with the function of overcoming obstacles. Background technique [0002] In recent years, with the rapid development of the logistics industry, the demand for AGV cars has also increased. There are AGV cars with various navigation methods, AGV forklifts, etc., and there are common one-way AGV cars and two-way AGV cars in the form of movement. And omnidirectional AGV trolley. At present, most of the fields of application of AGV trolleys are in industrial environments. [0003] Omni-directional wheels are in line with the design requirements of AGV trolleys, and can meet all-round wheel movement and rotation. However, the structure of omni-directional wheels determines that it cannot be used in general environments, such as hair, glue, dust, sand, etc. are easy to get stuck If the peripheral wheel is stuck, the direction of the force vector will ch...

AI Technical Summary

Problems solved by technology

[0004] Four-wheel drive fixed wheels: Since the direction of movement of the wheels is fixed, when the chassis of the trolley rotates, the wheel set will produce a large side slip, the accuracy will be reduced, and the rotation efficiency will be low

However, the disadvantage of this structure is that it cannot cross hurdles, go uphill, or cross obstacles: the car is supported by 4 wheels. When the car goes over obstacles, the front driven wheel and the rear driven wheel will separate the middle driving wheel from the ground, and the car will lose power. , unable to overcome obstacles
