The utility model provides a technical scheme that its technical problem adopted as follows:

Strenghthened type car surrounds, including the bounding wall, the cross section of bounding wall is L type structure, and the outer end of bounding wall highly is higher than the inner, and bounding wall outer end upper portion is equipped with inside sunken connecting portion, and the inner upper portion of bounding wall is equipped with ascending connection arch, the bounding wall be bilayer structure, the bounding wall includes planking, the inboard inner panel of planking, the connection of the gusset through the planking inner wall between planking, inner panel, the gusset is crisscross each other and is enclosed into a plurality of gusset chambeies, the gusset intracavity is filled and is shaken the bubble cotton, the planking that connecting portion department corresponds, the plate body of inner panel directly meet, the planking that the joint arch corresponds, the plate body of inner panel.

Furthermore, the connecting bulge is provided with a connecting buckle.

Furthermore, the outer wall of the outer plate is provided with a woven reinforcing layer.

Furthermore, the connecting part is connected with the vehicle body through a connecting screw.

Furthermore, both ends of the enclosing plate are provided with side plates, and the side plates are provided with a plurality of connecting holes.

The utility model has the advantages that: by adopting the scheme, the enclosing plate is of a double-layer structure consisting of the outer plate and the inner plate, the structural strength is high, the compression resistance and the shock resistance are good, the deformation and the damage are not easy, the service life is greatly prolonged, the shock absorption foam between the double-layer plates absorbs shock energy, the enclosing shock is eliminated, the enclosing weather resistance is improved, and the service life is further prolonged.

Drawings

The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

Fig. 1 is a schematic cross-sectional structure diagram of an embodiment of the present invention.

Fig. 2 is a schematic structural diagram of an embodiment of the present invention.

Wherein: the damping structure comprises an outer plate 1, a rib plate 11, a side plate 13, an inner plate 2, a connecting part 3, a connecting bulge 4, a connecting buckle 41 and damping foam 5.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1 and 2, the reinforced automobile surround comprises a surround plate, the cross section of the surround plate is of an L-shaped structure, the outer end of the surround plate is higher than the inner end, two ends of the surround plate are provided with side plates 13, the side plates 13 are provided with a plurality of connecting holes, the connecting holes are connected with corresponding positions of an automobile body, the side plates close the ends, the turbulence effect is improved, the inner end and the outer end are connected, the rigidity and the structural strength of the surround structure are improved, the upper part of the outer end of the surround plate is provided with a plurality of inward-concave connecting parts 3, the connecting parts 3 are uniformly arranged along the length direction, the connecting parts 3 are provided with screw holes and connected with the automobile body through connecting screws, the inner end of the surround plate is provided with upward connecting bulges 4, the connecting bulges 4 are uniformly distributed along the length direction, the connecting buckles 41 are arranged on the connecting bulges 4, the convenient installation operation, the connection protrusion 4 is arranged on the inner end inner side wall, the outer side of the connection protrusion 4 is connected with the inner end inner part, the bottom end of the connection protrusion 4 is connected with the bottom, the connection protrusion 4 is arranged at the position to play the role of a reinforcing rib, the structural strength at the position is improved, the cladding plate is effectively fixed, the cladding plate is of a double-layer structure, the cladding plate comprises an outer plate 1 and an inner plate 2 at the inner side of the outer plate 1, the outer plate 1 and the inner plate 2 are connected through a rib plate 11 on the inner wall of the outer plate 1, the rib plates 11 are mutually staggered to define a plurality of rib plate cavities, damping foam 5 is filled in the rib plate cavities, the outer plate 1 and the inner plate 2 are bonded or welded, the rib plates are mutually connected and play a mutual support, the outer plate and the inner plate are spaced, firstly, the double-layer structure has stronger structural strength, avoid the deformation of the surrounding stress, even under the condition of being impacted by external force, the effect of the force can be evenly dispersed between the two layers through the rib plates, the damage caused by overlarge local stress is avoided, the structure is high, the service life is prolonged, secondly, the inherent frequencies of the outer plate and the inner plate are different, the inherent frequency of the surrounding can be adjusted by connecting the outer plate and the inner plate into a whole, the vibration frequency of the surrounding is different from the vibration frequency of the vehicle body, the resonance with the vehicle body is avoided, the influence of the vehicle body vibration on the surrounding is reduced, the vibration absorption foam 5 filled in the cavity of the rib plate not only absorbs the vibration energy, the vibration is eliminated, the inherent frequency can be adjusted, the influence of the vibration on the surrounding is reduced, the influence of the vibration on the strength of the plate body is reduced, the weather resistance is improved, the service life is greatly prolonged, the connecting part 3 is formed by the inward, the plate body of planking, the inner panel that the protruding 3 department of connection corresponds directly meets, makes planking, inner panel all be connected with the automobile body, guarantees the structural strength of junction, improves the reliability of surrounding connection, and the outer wall of planking 1 is equipped with weaves the enhancement layer, weaves the enhancement layer and weaves by the cellosilk and form, improves the intensity of planking, and shock resistance makes the atress balanced the dispersing when the atress, increase of service life.
