The opening and closing and locking device of the tailgate of the van electric sweeper

Abstract

The invention discloses a van-type electric sweeping vehicle stern door opening, closing and locking device which comprises a stern door rotating mechanism mounted on a trash can stern door door plate (1), a driving mechanism mounted on a pressing claw shaft (29) and a stern door (26), a stern door opening and closing mechanism mounted at the top of the stern door (26), and a stern door locking mechanism mounted at the bottom of the stern door (26), wherein the driving mechanism is connected with each of the stern door opening and closing mechanism and the stern door locking mechanism through a connecting rod mechanism. According to the van-type electric sweeping vehicle stern door opening, closing and locking device, a pressing claw additionally arranged at the top of the stern door can tightly press the top of the stern door when a bottom claw locks the bottom of the stern door to prevent the situation that the top of the stern door rotate towards the direction far away from a vehicle body caused by excessive tight locking of the bottom of the stern door; air leakage and water leakage can be avoided through effective locking of the stern door of a trash can to prevent secondary pollution caused by release of trash in the sweeping vehicle trash can and to improve the sweeping effect.

Description

technical field [0001] The invention relates to an opening and closing and locking mechanism, in particular to an opening and closing and locking mechanism for a tailgate of a van electric sweeper. Background technique [0002] With the continuous improvement of people's living standards and the increasing awareness of urban environmental protection, it has become a consensus to prevent and control atmospheric smog and air pollution. Accelerating the promotion and application of new energy vehicles in the field of sanitation is conducive to solving the contradiction between economic development and the environment. As an important part of urban sanitation work, road sweepers have also ushered in a good opportunity for development. The appearance of road sweeper is an important symbol of urban civilization. It has multiple functions such as road cleaning and spray dust reduction. It can be widely used in urban roads, airports, and other road cleaning. Many benefits, improve ...

Problems solved by technology

Traditional sweeping vehicles are usually driven by internal combustion engines, which not only generate huge noise and affect the surrounding environment, but also are limited to low-speed driving conditions, resulting in low engine efficiency and insufficient fuel combustion to produce a large amount of harmful gases, which does not conform to the concept of energy conservation and environmental protection
