The invention relates to the technical field of automobile collision prevention, and discloses a collision protection device for a front bumper and a rear bumper of a new energy automobile. The device comprises an air bag buffering device, the air bag buffer device comprises a fixed air bag; upper rotating rods are rotationally mounted at the left and right ends of the fixed airbag; a lower rotating rod is rotationally mounted below the upper rotating rod; a pushing block is fixedly installed at the left end of the lower rotating rod, a lower connecting block is slidably installed in the middle of the pushing block, and a multi-connecting-rod buffering device is fixedly installed below the lower connecting block. According to the collision protection device for the front and rear bumpers of the new energy automobile, the fixed air bag is pressed through the connecting plate, so that the fixed air bag is compressed to absorb energy; meanwhile, the fixed air bag drives the lower rotating rod to rotate through the upper rotating rod, so that the lower rotating rod drives the pushing block to move, and the pressed plate is driven to move under the combined action of the pushing block and the fixed connecting body; therefore, the effect of secondary energy absorption through the fixed air bag is achieved.
本发明涉及汽车防撞击技术领域,且公开了一种用于新能源汽车前后保险杠撞击保护装置,包括气囊缓冲装置,气囊缓冲装置包括有固定气囊,固定气囊的左右两端转动安装有上转动杆,上转动杆的下方转动安装有下转动杆,下转动杆的左端固定安装有推动块,推动块的中间滑动安装有下连接块,下连接块的下方固定安装有多连杆缓冲装置。该用于新能源汽车前后保险杠撞击保护装置,通过连接板压动固定气囊,使固定气囊压缩吸能,同时固定气囊通过上转动杆带动下转动杆转动,使下转动杆带动推动块运动,在推动块与固定连接体的共同作用下带动受压板运动,从而达到了通过固定气囊进行二次吸能的效果。
