Description

Deformation-preventing vehicle guard plate bolt mounting structure

Technical Field

The utility model belongs to the technical field of the production installation of automobile parts and specifically relates to a guard plate bolt mounting structure for automobile of preapring for an unfavorable turn of events shape.

Background

Traditional backplate majority direct mount is in the car surface, utilizes its firm surface to protect the car, but current backplate does not have shock-absorbing function, and the huge impact after receiving the striking can directly transmit to the car surface through backplate to lead to the automobile structure impaired.

The automobile chassis backplate is the engine protector according to various different motorcycle types design of stereotyping, and its design at first prevents earth parcel engine, leads to the engine heat dissipation bad, secondly prevents because unevenness's road causes the striking or scrapes the damage that causes the engine to the engine in order to go the in-process, reaches extension engine life through a series of designs, avoids going out the in-process because external factor leads to the car of engine damage to break down. In addition, the automobile chassis guard plate can keep the engine bin clean, prevents that surface gathered water dust from getting into the engine bin to can prevent that the grit hard thing that the tire rolled up after rolling in the automobile driving process from knocking the engine, in the long run, cause the engine damage trouble easily.

The prior fixing methods of the automobile guard plate and the frame are two, one of which is to use a screwing method to drill a plurality of screw holes on the combination position of the automobile guard plate and the frame by an electric drill and then screw and fix the screw holes by screws. However, the screw fastening method used in the aforesaid sunday is a safe method for firmly combining the spoiler with the vehicle body, but it damages the structure of the vehicle body, so that the drilled portion is rusted due to the leakage of rain water, and it is not favorable for the aerodynamic structure, so it is not very suitable for the vehicle owner. Moreover, at least parts of the frame and the automobile guard plate are made of hard materials (metal materials such as aluminum alloy, cast iron and the like or hard plastics), so if the frame and the automobile guard plate are directly fixed by bolts, the situation that the extrusion force is too large in the installation process can be caused, the frame or the guard plate is deformed, and the normal use performance of the frame or the guard plate is further influenced. In addition, ordinary screw structure is single, and its locking force is general, and the vehicle running environment is all comparatively jolted, consequently the condition that the screw pine takes off appears easily, and then leads to the backplate to drop from the frame.

The two bonding methods are to bond and fix them by glue and double-sided adhesive tape. The double-sided adhesive tape is used by many people, and the adhesive strength is limited without destroying the structure of the car body, so that the car cannot endure the pulling of strong airflow force for a long time, and the car is easy to fall off to cause accidents, which is a potential defect.
