Electric truck facilitating loading and unloading

Abstract

The invention discloses an electric truck facilitating loading and unloading. The electric truck comprises a front frame, a rear frame and a connecting frame, wherein the front frame and the rear frame are fixedly connected through the connecting frame; rear wheels are installed on the bottom of the rear frame, lifting devices are fixedly arranged in the rear frame, at least two longitudinal grooves are formed in the upper surface of the rear frame, rolling belts are arranged in the grooves in a vertically-rolling mode, the bottoms of the rolling belts are connected with the lifting devices, ball grooves are formed in the upper surfaces of the rolling belts, rolling balls are restrained in the ball grooves, and the distance between the center of each rolling ball and the upper surface of the corresponding ball groove is smaller than the radius of the rolling ball, so that when cargoes are loaded, the lifting devices drive the rolling belts up, the upper surfaces of the ball grooves coincide with the upper surface of the rear frame, and the cargoes can roll on the rolling balls, so that friction force is greatly reduced, and during transportation, the lifting devices make the rolling belts down, and the cargoes are in contact with the upper surface of the rear frame again, so that friction force is increased, and then the cargoes do not slide during transportation. Therefore, loading and unloading of the cargoes are conveniently achieved.

Description

The battery is used as the power source, the motor is used as the power, and the vehicle is driven through gear transmission. It has the advantages of labor saving, high efficiency, stable cargo operation, simple operation, safety and reliability, low noise, green environmental protection, energy saving, and convenient parking. Moreover, the convenience of carrying goods and people is more and more popular among people. Electric pallet trucks are widely used in various fields of daily life. For example, electric pallet trucks have been widely used by major express companies as special tools for delivery and transportation. Electric trucks are also widely used in greenhouses to carry fruit and vegetable boxes. The existing electric trucks are time-consuming and laborious when loading and unloading some heavy items, and the operation is inconvenient.
