Electric automobile chassis system

Abstract

The invention discloses an electric automobile chassis system which comprises an automobile frame, an automobile frame widening device, a walking steering device, a turnover trunk and a turnover trunk driving mechanism. The vehicle frame widening device comprises two widening plates slidably mounted on the two sides of the automobile frame correspondingly, a linear moving mechanism used for driving the two widening plates to stretch out and draw back, and a first driving mechanism connected with the linear moving mechanism. The walking steering device comprises a plurality of walking wheels installed on the widening plate, a steering transmission mechanism used for driving the walking wheels to steer synchronously and a second driving mechanism connected with the steering transmission mechanism, and the steering transmission mechanism comprises a first transmission assembly, a linkage rod and a second transmission assembly. The structure is simple, the purpose of widening the automobile frame can be achieved, the synchronous steering precision of the walking wheels can be improved, the walking stability of the electric automobile after the automobile frame is widened can be guaranteed, manual control over the turnover trunk can be achieved, and the safety of movement of the turnover trunk can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an electric vehicle chassis system. Background technique [0002] At present, the types of electric vehicles include pure electric vehicles (BEV), hybrid electric vehicles (HEV), and fuel cell vehicles (FCEV). The function of the automobile chassis system is to support and install the electric drive and its components, form the overall shape of the electric vehicle, and accept the power of the electric drive to make the electric vehicle move and ensure the normal driving of the electric vehicle. However, the existing electric vehicle chassis system has the following defects: first, the steering accuracy is poor, which is mainly manifested in: the steering radius is relatively large, which is not suitable for use in a narrow space; the steering is not flexible enough, and the overall steering of the car body must be turned to change the walking direction ; C...

Problems solved by technology

However, the existing electric vehicle chassis system has the following defects: first, the steering accuracy is poor, which is mainly manifested in: the steering radius is relatively large, which is not suitable for use in a narrow space; the steering is not flexible enough, and the overall steering of the car body must be turned to change the walking direction ; Can not move parallel to other directions arbitrarily, nor can it turn in situ, so the flexibility of movement is relatively poor, and parking is inconvenient; the space required for parking is relatively large, resulting in low parking density in the parking area, which makes parking in urban areas difficult; 1. The chassis cannot be widened, and the trunk cannot be turned over, resulting in limited compartment capacity; in order to solve the above defects, therefore, an electric vehicle chassis system should be provided
