Novel trolley capable of moving forwards in desert

Abstract

The invention discloses a novel trolley capable of moving forwards in a desert. The novel trolley comprises a trolley body, wherein a connecting rod is arranged on the trolley body; a supporting seat is arranged at the middle point of the connecting rod; the connecting rod is hinged with the supporting seat; the left end and the right end of the trolley body are symmetrically provided with a motor and a spiral shaft; the spiral shafts are connected with output shafts of the motors by transmission devices; connecting seats are arranged at the two ends of the spiral shafts; the top ends of the connecting seats, close to the motors, are provided with first supporting rods; the connecting seats are hinged with the first supporting rods; the top ends of the connecting seats, far away from the motors, are provided with second supporting rods; the trolley body is provided with a first sliding groove; two fixed seats are symmetrically arranged at the front end of the trolley body; a movable rod is arranged between the two fixed seats; a steering engine is arranged on the trolley body and is provided with a gear; and a rack is arranged on the movable rod. The novel trolley disclosed by the invention has the beneficial effects that the spiral shafts are used for replacing tires, so that the friction with the ground is increased, the ground gripping force is stronger, and the trolley is not easy to trap in looser sandy soil.

Description

technical field [0001] The invention mainly relates to a desert walking tool, in particular to a new type of desert walking trolley. Background technique [0002] The desert is dry and barren, there are a lot of high or low sand dunes and soft sand, and the road surface is soft, causing the vehicle to not grip the ground firmly, making it difficult to walk, and it is often difficult to move an inch, and the wheels are easily trapped by the soft sand during driving. Especially when the wheels are slipping, if the horsepower is forcibly increased, the wheels will sink further, and in severe cases, the vehicle will not be able to drive; and, due to the soft road surface, the car will have understeer, oversteer, brake skid, and poor climbing ability in the desert. Disadvantages, when crossing obstacles, the wheels are prone to skidding, and in severe cases, it will cause rollover, and even cause casualties. In addition, there are sandstorms and quicksands in the desert that may ...

Problems solved by technology

[0002] The desert is dry and barren, there are a lot of high or low sand dunes and soft sand, and the road surface is soft, which makes the vehicle not grip the ground firmly, and it is difficult to walk, and it is often difficult to move an inch , and the wheels are easily trapped by the soft sand during driving, especially when the wheels slip, if the horsepower is forcibly increased, the wheels will sink further, and in severe cases, the vehicle cannot be driven; and, due to the soft road surface, the car in the desert There are shortcomings such as understeer, oversteer, brake slippage, and poor climbing ability. When crossing obstacles, the wheels are prone to skidding, which may cause rollover and even casualties in severe cases. In addition, there are sandstorms and quicksands in the desert. Vehicles may be buried, so ordinary vehicles cannot drive normally in the desert
