Abstract

The invention provides a novel electric automobile trunk cover driving mechanism. The novel electric automobile trunk cover driving mechanism comprises a driving box and a connecting rod assembly connected with the driving box, the connecting rod assembly comprises a connecting rod and a connecting rod support, a screw assembly, a reversing speed reducer and a motor assembly are arranged in the driving box, the screw assembly comprises a transmission screw, a nut sliding block and a sliding block guide rod, the transmission screw is in threaded connection with the nut sliding block, and the nut sliding block is in sliding fit with the sliding block guide rod. The reversing speed reducer comprises an output shaft gear, an intermediate shaft gear and an input shaft gear. According to the driving box of the mechanism, different electric automobile types do not need to be changed, only the length of the connecting rod needs to be adjusted, the mechanism can adapt to various electric automobile types, the sliding block mechanism is adopted, a driving assembly is completely fixed, only the sliding block does linear motion within a limited range, the motion enveloping surface is small, and the whole mechanism is convenient to install and arrange and small in occupied space.

Description

technical field [0001] The invention relates to the technical field of driving the trunk lid of an electric vehicle, in particular to a novel driving mechanism for the trunk lid of an electric vehicle. Background technique [0002] With people's attention to environmental protection and the development and maturity of related technologies, more and more electric vehicles are used by people. Electric vehicles are zero-emission during use, making people attach great importance to them, and are considered to be an important choice for future transportation. Like traditional cars, there is a trunk with storage space on the rear side. At present, the trunk of an electric car mainly uses two driving mechanisms to realize the opening and closing of the trunk lid, that is, a guide rod mechanism and a four-bar linkage mechanism. In the guide rod mechanism, the guide rod has a built-in motor, one end is fixed and hinged to the body sheet metal, and the other end is hinged to the hing...
