Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to 3, the utility model relates to a enclose skeleton behind car, including protecting crust 2, automobile body 1, square frame 3 and buffer board 4, square frame 3 and protecting crust 2 fixed connection, buffer board 4 is connected with square frame 3 joints through a plurality of buffer spring 5, a plurality of slide bar 6 of 3 fixedly connected with of square frame, be equipped with a plurality of sliding sleeves 7 on every slide bar 6, every sliding sleeve 7 is connected with square frame 3 lateral wall joints through expanding spring 8, buffer board 4 is close to square frame 3's lateral wall and rotates and be connected with a plurality of support frames 15, a plurality of support frames 15 respectively with a plurality of sliding sleeve 7 fixed connection, protecting crust 2 is connected with automobile body 1 joint, protecting crust 2 is close to a plurality of fixed frames 9 of lateral wall fixedly connected with of automobile body 1.

The side wall of the protective shell 2, which is close to the space between the fixed frames 9, is provided with a plurality of first threaded holes, the side wall of the vehicle body 1, which is close to the first threaded holes, is provided with a plurality of second threaded holes matched with the first threaded holes, each first threaded hole and each second threaded hole are connected with a threaded strip 10 through threaded rotation, the side wall of each threaded strip 10 is fixedly connected with a plurality of second gears 11, the side wall of the protective shell 2 is rotatably connected with a plurality of rotating rods 12, each rotating rod 12 is fixedly connected with a plurality of first gears 13, the plurality of first gears 13 are connected with the plurality of second gears 11 through rack chain transmission, one end of each rotating rod 12, which is far away from the protective shell 2, is fixedly connected with a rotating disk 14, and the fixed frames 9 can protect the structures such as the threaded strips 10, the rotating rods 12 and the rotating disk 14, thereby protect structures such as screw thread strip 10 can not damaged by the distortion in the accident, guarantee that protective housing 2 can break away from automobile body smoothly behind the accident.
