Embodiment 1

[0021] In this embodiment, in order to improve the anti-collision performance of the overall structure, preferably, open-shaped connecting pipes 111 are respectively provided at both ends of the sleeve 105, so that the connecting pipes 111 are sleeved on the Outside the beam 104, the inner diameter of the connecting pipe 111 near the end of the sleeve 105 is larger than the inner diameter of the other end, so that the connecting pipe is welded or connected to the two ends of the sleeve through a flange, or connected by other means , a torsion spring is arranged inside the connecting pipe 111, so that one end of the torsion spring is fixedly connected to the connecting pipe, and the other end is fixedly connected to the beam. When the sleeve 105 drives the connecting pipe 111 to rotate, it can Make described torsion spring torsion. By adopting the connecting pipe structure, the inner side of the connecting pipe is equipped with a torsion spring structure. When the casing is rel...

Embodiment 2

[0023] Since some bumpers are made of brittle materials, they are easily broken when they are impacted. When the buffer spring group inside the sleeve produces elastic force on the sleeve, the sleeve may be under the action of the buffer spring group. Reciprocating movement is generated, so that the front cover is easily broken under the reciprocating force. In this embodiment, in order to avoid the reciprocating movement of the sleeve when the buffer spring group exerts force on the sleeve, preferably, the front A buffer plate 112 is arranged on the end surface of the cover body 101 facing the rear cover body 102, so that the buffer plate is fixedly connected to the front cover body, and the buffer plate points to the rear cover body, and is arranged on the rear cover body 102. There is a sinking groove 113 corresponding to the position of the buffer plate 112, so that the buffer plate 112 can be inserted into the inside of the sinking groove 113, and a retaining edge 114 is p...

Embodiment 3

[0025] In this embodiment, in order to facilitate the mutual connection between the front cover and the rear cover, preferably, slide grooves are respectively provided on the end faces of the two ends of the front cover 101 facing the rear cover 102 117, make the length direction of the chute parallel to the length direction of the front cover, and the end of the connecting rod 109 away from the rear cover 102 is provided with a slider 118 capable of sliding along the chute 117, The slider 118 is rotatably connected to the connecting rod 109 .

Abstract

The invention discloses a new energy electric car. A bumper of the new energy electric car comprises a front cover body and a rear cover body, two supports are arranged on the sides, facing the front cover body, of the two ends of the rear cover body, a beam is arranged between the two supports and sleeved with a sleeve pipe, and bosses are arranged outside the sleeve pipe; a pressing plate is arranged on the side, facing the rear cover body, of the front cover body, one end of the pressing plate is rotatably connected to the front cover body, and the other end of the pressing plate is rotatably connected to the bosses; and at least three buffering spring sets are arranged on the beam and each composed of high-strength springs distributed at equal intervals in the circumferential direction of the outer wall of the beam. According to the new energy electric car, by means of the structure that the buffering spring sets are connected with the sleeve pipe, when the front cover body is under the external impacting effect, the effect of buffering acting force can be achieved through the pressing plate connected with the sleeve pipe.

Description

technical field [0001] The invention relates to a new energy electric vehicle and belongs to the technical field of automobiles. Background technique [0002] Automobile bumpers can protect the body, absorb and buffer the impact caused by external collisions. The car bumper is generally fixed on the anti-collision beam. Existing brakes generally can only absorb extremely limited impact, and are limited to safety protection for low-speed operation, and the safety is not high enough. Contents of the invention [0003] The purpose of the present invention is to provide a new energy electric vehicle, the bumper of which is connected to the sleeve structure by using a buffer spring group, when the front cover is subjected to external impact, the pressure plate connected to the sleeve can play a buffering force effect. [0004] The present invention is realized through the following technical solutions: [0005] A new energy electric vehicle, including a bumper, the bumper in...
