Description

Buffer structure of electric vehicle bumper Technical Field The utility model relates to the technical field of electric vehicles, in particular to an electric vehicle bumper buffer structure. Background At present, the common electric vehicle bumpers on the market are simpler in structure and mostly only play a basic role in protection. The conventional bumper is generally made of a rigid material, and when the bumper is impacted, the rigid bumper can block external force to a certain extent, but most impact force is directly transmitted to the main body of the electric vehicle due to lack of an effective buffer mechanism, so that the problems of deformation of the vehicle body, damage of parts and the like are easily caused, and the maintenance cost is increased. Moreover, the larger impact force may cause injury to the rider, and particularly, when a serious collision occurs, the rigid bumper cannot effectively reduce the impact of the impact force on the rider. Disclosure of utility model In view of the above-mentioned technical shortcomings, the present utility model aims to provide an electric vehicle bumper buffer structure, which can make the bumper play a role in buffering and fully absorb impact force when an electric vehicle collides. In order to solve the technical problems, the utility model adopts the following technical scheme that the utility model provides an electric vehicle bumper buffer structure, which comprises: a guard board and a connecting frame; The buffer parts comprise a first connecting plate, a second connecting plate and an elastic telescopic part, wherein two ends of the elastic telescopic part are respectively connected with the first connecting plate and the second connecting plate, the outer side of the elastic telescopic part is provided with a tight propping mechanism, and when the first connecting plate and the second connecting plate are gradually close to each other, the tight propping mechanism is propped against the middle part of the elastic telescopic part; Wherein, the backplate is connected with the electric motor car through the link. Preferably, the elastic expansion member includes: an outer cylinder fixed on the first connection plate; the inner cylinder is fixed on the second connecting plate, and one end of the inner cylinder far away from the second connecting plate is inserted into the outer cylinder; The spring is arranged in the inner cylinder, and two ends of the spring respectively prop against the first connecting plate and the second connecting plate.
