Embodiment 1

[0030] As shown in the figure, a new energy vehicle bumper is produced, including a bumper body, the bumper body includes an inner bumper 1 and an outer bumper 2, and the inner bumper 1 and the outer bumper 2 are made of light metal materials or polypropylene plastics The inner bar 1 and the outer bar 2 are connected by a spring screw 3; the inner bar 1 is fixed with a mounting seat 4, which is used to rivet the mounting seat 4 on the frame longitudinal beam; the inner bar 1 There are several through holes corresponding to each other on the bar 1 and the outer bar 2.

[0031] Described spring screw rod 3 comprises two screw rods 5 and a spring 6, and these two screw rods 5 are respectively fixedly connected on the seat ring 7 at two ends of spring 6, and the outer diameter of described screw rod 5 matches with through hole, makes screw rod 5 Can just pass through the through hole, the outer diameter of the seat ring 7 is greater than the inner diameter of the through hole, so ...

Embodiment 2

[0034] On the basis of embodiment 2, each nut 8 is also equipped with a washer, and the washer is a lock washer 9, and the double sides of the lock washer 9 are provided with radial tooth marks 10, so that when the nut 8 is tightened It is not easy to unscrew in reverse.

[0035] The outer end surface of the screw rod 6 is also provided with a fixing mechanism. In this embodiment, a cross-shaped groove is dug on the outer end surface of the screw rod. When the nut is about to be tightened, the screw rod will rotate with the rotation of the nut. The screwdriver is embedded in the screw rod so that the screw rod cannot be rotated, and then the nut is tightened with a wrench, and the nut can be tightened smoothly.

[0036] In addition, a decorative cover 11 is made, the decorative cover 11 is made of rubber material, and the inner bar 1 and the outer bar 2 of the bumper are all covered with the decorative cover 11, which can play a decorative role on the bumper, and cover and sea...

Embodiment 3

[0038] The installation method of described new energy vehicle bumper comprises the steps:

[0039] First make the spring screw rod 3, get a spring 6 and two screw rods 5, the outer diameter of the screw rod 5 is equal to the inner diameter of the spring 6, one end of a screw rod 5 is fixedly welded on the one end seat ring 7 of the spring 6, the screw rod 5 is called the front-end screw rod 12; one end of the other screw rod 5 is fixedly welded on the other end race 7 of the spring 6 to make a spring screw rod 3, and the other screw rod 5 is called the rear-end screw rod 13; thus making several springs Screw rod 3; Be equipped with nut in addition.

[0040] The inner bar 1 and the outer bar 2 of the bumper are injection-molded with polypropylene plastic, and through holes are preset at the design positions on the inner bar 1 and the outer bar 2 . Make decorative cover 11 according to the molding of inner bar 1 and outer bar 2 with elastic rubber material, make decorative cov...

Abstract

A new energy vehicle bumper belongs to the technical field of automobile safety and comprises an inner bumper and an outer bumper, and the inner bumper and the outer bumper are provided with a plurality of through holes in one-to-one correspondence and connected through spring screws. Each spring screw is formed by fixedly connecting two screws to the seat rings at the two ends of the corresponding spring, the two ends of the multiple spring screws penetrate through the through holes in the inner bumper body and the through holes in the outer bumper body respectively and are fixed through nuts, and the new energy vehicle bumper is formed. In addition, a lock washer is arranged, and a cross-shaped groove is formed in the outer end face of the screw in a digging mode. The new energy vehicle bumper has the beneficial effects that the bumper is elastic by adopting the spring screw rod, the bumper can play an elastic buffering role when being impacted, and the bumper can play a double-layer buffering role in combination with the hard buffering of the bumper; according to the automobile bumper, the inner bumper, the outer bumper and the elastic rubber decorative sleeve, a safety device with a multi-stage elastic buffering effect is formed, so that the safety of an automobile when the automobile is impacted is greatly improved, and meanwhile, the injury to pedestrians can be reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, in particular to a new energy automobile bumper. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. [0003] The front and rear bumpers are important parts of new energy vehicles. The current bumper structure is generally processed as a whole, and it also functions as a casing. There are two key problems in such a bumper structure. One is that when the car is hit by a collision, the cushioning effect is achieved by damaging the bumper. It is a hard cushion and the cushioning effect is not good enough; the other is that when the bumper is partially damaged , the entire car bumper must be replaced, causing great inconvenience to vehicle maintenance and increa...
