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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: the utility model provides an automobile muffler lifting hook that crashworthiness is high, including chassis support 1, screw 3 has been seted up to chassis support 1's the lower surface left and right sides, the inside spiro union of screw 3 has bolt 4, buffer 5 has been cup jointed to bolt 4's surface, buffer 5 includes the supporting seat 51 with the 1 lower surface of chassis support closely laminating, supporting seat 51 has muffler 2 with the inboard of chassis support 1 closely laminating, supporting seat 51's lower surface closely laminates and has blotter 54, the lower extreme of blotter 54 closely laminates corrugated metal sheet 55, the lower extreme of corrugated metal sheet 55 closely laminates and has shell 53, bolt 4 spiro union is passed through at chassis support 1's lower surface left and right sides at both ends about shell 53, block rubber 52 has been cup jointed to bolt 4's surface, block rubber 52 is located between supporting seat 51 lower surface and the shell 53 upper surface.

The shell 53, the rubber block 52 and the supporting seat 51 are screwed under the chassis support 1 through the matching of the bolts 4 and the screw holes 3, the internal cushion pad 54, the corrugated metal plate 55 and the rubber block 52 have different buffering and absorbing capabilities, the impact on the shell 53 is absorbed in a graded manner, the buffering capability is strong, and the protection effect on the sound absorber is better.

The supporting seat 51 is of a U-shaped structure, and circular through holes 6 are uniformly formed in the lower surface of the supporting seat 51. The heat of the internal silencer can be dissipated.

The shell 53 is of a U-shaped structure, the shell 53 is slidably mounted on the outer side of the supporting seat 51, the shell 53 moves upwards to press the rubber block 52 when being impacted, the impact force is absorbed through the rubber block 52 firstly, the left side and the right side of the shell 53 are uniformly provided with special-shaped through holes 7 matched with the corrugated metal plate 55, the special-shaped through holes 7 are communicated with the upper side of the corrugated metal plate 55, and heat entering the circular through holes 6 can be absorbed and dissipated outwards.

The bolt 4 comprises nuts 43 tightly attached to the left side and the right side of the lower surface of the shell 53, a polished rod 42 is fixedly mounted at the upper end of each nut 43, the length of each polished rod 42 is equal to the length between the upper surface of the supporting seat 51 and the lower surface of the shell 53, a rubber block 52 is sleeved on the outer surface of each polished rod 42, a threaded rod 41 is fixedly mounted at the upper end of each polished rod 42, and the length of each threaded rod 41 is smaller than the depth of each screw hole.

The polished rod 42 on the upper end of the nut 43 facilitates the movement and recovery of the stress deformation of the rubber block 52, reduces the friction force, and the threaded rod 41 and the screw hole 3 can be tightly screwed and matched without interfering the relative movement of external parts, thereby avoiding the loss of the parts.

The number of the screw holes 3, the bolts 4 and the rubber blocks 52 is four respectively, and two bolts are arranged on each side of the left side and the right side of the chassis support 1. The screw holes 3, the bolts 4 and the rubber blocks 52 which are uniformly distributed on the two sides can move relatively more stably, and the stress is uniform.

The working principle is as follows: when the road jolts, when there is external force to strike shell 53, shell 53 upwards removes oppression rubber block 52, blotter 54 along the direction of polished rod 42 and carries out preliminary buffering and absorption, if external force is too big, corrugated metal plate 55 can warp between shell 53 and supporting seat 51, absorbs stronger impact force, avoids damaging the inside muffler of supporting seat 51, and buffer capacity and protection effect are better.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
