Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to an anti-collision structure of an obstacle-avoiding lithium-ion electric vehicle. Background Art

[0002] Obstacle-avoiding lithium-ion electric vehicles refer to electric vehicles that use lithium-ion batteries as energy and have obstacle avoidance functions. During operation, lithium-ion electric vehicles can perceive the surrounding environment in real time through various sensors, such as cameras, radars, lidars, etc. These devices can detect obstacles, pedestrians, vehicles, etc. on the road, and transmit data to the control system. The control system makes decisions quickly based on this data and combined with preset algorithms to adjust the vehicle's driving direction and speed to avoid obstacles and ensure driving safety.

[0003] At present, the lightweight electric vehicles on the electric vehicle market blindly pursue small size and light weight, and ignore the establishment of protective devices of electric vehicles, which makes the parts easy to be damaged when an accident occurs, reducing the service life of the electric vehicle. Based on these problems, Chinese patent CN211642434U discloses a lightweight lithium battery mini car with a protective structure. The pedal is wider than the other parts of the frame, which can ensure that the pedal and the seat touch the ground when the electric vehicle falls, and other parts will not be bumped. Protective steel is arranged around the pedal and the seat, and a hard sponge layer is wrapped on the protective steel. The outer side of the hard sponge layer is wrapped with an elastic shell. The material of the elastic shell can be an elastic material with strong impact resistance and wear resistance such as micro-elastic plastic. The hard sponge layer and the elastic shell play a buffering role. The protective steel protects the pedal and the inside of the seat from being damaged. A storage box is arranged inside the pedal. The storage box is used to place batteries, controllers, etc. A plurality of springs are arranged between the outer side of the storage box and the inner wall of the pedal. The springs play a buffering role to protect the batteries and the controller.

[0004] The storage box structure inside the pedal of the lithium-ion battery vehicle is relatively simple and cannot provide good anti-collision protection for the lithium battery. At the same time, the shaking of the spring can easily cause the spring to deform, thereby affecting the shockproof effect inside the pedal. Summary of the invention
