Detailed Description

The following detailed description of the embodiments of the utility model, given by way of example only, is presented in the accompanying drawings to aid in a more complete, accurate, and thorough understanding of the concepts and aspects of the utility model by those skilled in the art.

As shown in fig. 1 to 8, the present utility model provides a subframe body mounting sleeve structure, characterized in that: the bending arm comprises a bending arm outer plate 1, a bending arm sleeve 3 and a grooving sleeve 4, wherein the front side of the bending arm outer plate 1 is provided with a bending arm inner plate 2, a plurality of positioning holes 21 are formed in the bending arm inner plate 2, the bending arm sleeve 3 is arranged at the upper end of the front side of the bending arm outer plate 1, the bending arm sleeve 3 is of a cylindrical structure formed in a punching and splicing mode, a plurality of positioning convex blocks 31 are arranged on one side of the bending arm sleeve 3, positioning grooves 32 matched with the positioning convex blocks 31 one by one are formed on the other side of the bending arm sleeve 3, side notches 33 are respectively formed at the upper end and the lower end of the bending arm sleeve 3, the grooving sleeve 4 is arranged at the top of the bending arm sleeve 3, a U-shaped notch 41 corresponding to the side notch 33 at the upper end of the bending arm sleeve 3 is formed in the side of the grooving sleeve 4, and a top notch 42 communicated with the U-shaped notch 41 is formed at the top of the grooving sleeve 4.

It should be noted that the bottom of the bent arm outer plate 1 is provided with a flanging edge 11, the rear side of the bent arm outer plate 1 is provided with a plurality of side mounting holes 12, and the bent arm outer plate 1 is mounted through the side mounting holes 12.

Specific embodiments and principles:

in practical application, the U-shaped notch 41 is reserved on the slotted sleeve 4, so that a bolt of a vehicle body can conveniently and smoothly fall off through the notch in collision, meanwhile, the bent arm sleeve 3 is also changed into a cylindrical structure formed by splicing stamping parts from the original seamless sleeve structure, and when a vehicle performs a collision test, the bolt can fall off through the spliced part of the bent arm sleeve 3, and the auxiliary frame is bent to drive the engine to sink, so that the engine is prevented from invading a passenger cabin, and the safety performance of the vehicle is improved.

While the utility model has been described above with reference to the accompanying drawings, it will be apparent that the utility model is not limited to the above embodiments, but is capable of being modified or applied to other applications without modification, as long as the inventive concept and technical scheme are adopted.
