Front protection structure of electric tricycle

Abstract

Provided is a front protection structure of an electric tricycle. The front protection structure includes an inner cross beam, inner bevel edge beams which are symmetrically and fixedly connected ontothe left and right ends of the inner cross beam, an outer cross beam and two outer bevel edge beams; the outer end of the inner bevel edge beam is close to the direction of a tricycle body in the rear, the inner cross beam and the inner bevel edge beams are all fixedly connected with the front part of the tricycle body, the outer cross beam is arranged at the front part of the inner cross beam, and is parallel to the inner cross beam, and the outer cross beam is fixedly connected with the inner cross beam through two connecting beams perpendicular to the inner cross beam; the inner end of each outer bevel edge beam is hinged with the left and right ends of the outer cross beam separately; the two outer bevel edge beams are connected with the two inner bevel edge beams through buffer mechanisms; each buffer mechanism is composed of a first spring base fixedly connected onto the middle part of the corresponding inner bevel edge beam, a second spring base fixedly connected onto the middle part of the corresponding outer bevel edge beam, and a compression spring fixedly connected between the first spring base and the second spring base. The protection structure has deformation resilience capacity after deformation, has the function of energy absorption in the process of collision, and can better protect the safety of the electric tricycle and users.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a front protection structure of an electric tricycle. Background technique [0002] With the popularization and promotion of electric vehicles, people put forward higher and higher requirements for the safety of electric vehicles. Generally all can install protective bumper at the front portion of electric tricycle. The performance of the front bumper directly affects the safety performance of the electric vehicle. [0003] The front bumper in the existing technology mainly has the following disadvantages: after the impact, it will deform, and then can not better protect the front wheel and the user; after the deformation, it needs to be repaired; However, the buffer performance is not ideal. Contents of the invention [0004] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a front protection structure of...
