Description

Tailstock skirt section assembly

Technical field

The utility model belongs to field of automobile, is related to a kind of tailstock skirt section assembly.

Background technique

Traditional tailstock skirt section assembly, since tailstock skirt section assembly cavity is Y-direction (width of the carbody direction) opening, and with Need intermediate connector to splice between left and right side wall, structure is relative complex, installation left and right side wall rear car tail skirt section assembly without Method normal mounting in assembly first will must carry out again left and right side after tailstock skirt section assembly and Frame Welding and enclose to spell, then exist Top cap rear cross beam assembly is overlapped at the top of left and right side wall；This structure makes tailgate frame tailstock skirt section assembly, top cap rear cross beam assembly two The piece uploading of a components is distributed in two in-process, and process distance is remote, and process deviation accumulation is big, and leading to tailgate frame Z-direction, (car body is high Spend direction) size is unstable, and the adjustment of tailgate assembly clearance face difference is difficult；And the tailstock skirt section assembly of assembling process design, only Can be designed as extending limited with side wall mating interface form, cavity, effective reinforcement can not be formed, on vehicle twisting property influence compared with Greatly；In addition, rear skirt section outside plate stock utilization is lower, the welding of D column assembly and tailstock skirt section assembly need to increase intermediate connector It is attached, increases die cost and welding sequence.

It therefore, it is necessary to improve tailstock skirt section assembly structure, makes it easier to install, reduces assembly process, reduce work Sequence deviation accumulation promotes vehicle body torsional strength.

Utility model content

In view of this, the present invention provides a kind of tailstock skirt section assemblies, make it easier to install, and reduce assembly process, drop Low process deviation accumulation promotes vehicle body torsional strength.

The tailstock skirt section assembly of the utility model, including with hull back match in metal plate shape rear skirt section outside plate and It is integrated in the rear skirtboard connecting plate on rear skirt section outside plate for splicing with left and right side wall.

Further, Mosaic face smooth transition on the inside of the rear skirtboard connecting plate.

Further, the installation bracket for protecting after installing is integrated on the rear skirt section outside plate.

Further, there are the first domes extended along its length on the rear skirt section outside plate.

Further, the tailstock skirt section inside panel of metal plate shape is fitted on the inside of the rear skirt section outside plate.

Further, there are the second domes extended along its length on the inside panel of the tailstock skirt section.

Further, half chamber that the opposite face of the rear skirt section outside plate and tailstock skirt section inside panel has domes to be formed, two A half chamber is encircled into closed cavity.

Further, the closed cavity extends total for placing D column with left and right side along rear skirt section outside plate length direction At connecting.

The utility model has the beneficial effects that

The utility model tailstock group portion assembly is integrated with rear skirtboard connecting plate, can directly splice with left and right side wall, reduce Intermediate connector improves splicing efficiency, avoids deviation accumulation when intermediate connector connection, improves tailgate frame assembly essence Degree, reduces the components of assembly through this structure, has saved mould development expense, greatly improve the material of rear group portion outside plate Utilization rate；

Mosaic face smooth transition is not provided with complicated connection structure, this structure on the inside of skirtboard connecting plate after the utility model It ensure that after the installation of left and right side wall, tailstock group portion assembly can effectively be spliced in car body front-rear direction and left and right side wall, In assembly, this structure may make assembled sequence becomes first enclosing left and right side to spell on vehicle frame, then by tailstock skirt section assembly, top Cover and rear frame member assembly is assembled in left and right side and places, and tailstock skirt section assembly and top cap rear cross beam can be completed in one group of assembling procedure The assembly of assembly improves main line and spells technique, and tailgate frame becomes two assembling procedures from three assembling procedures, simplifies group Process is filled, assembling procedure is reduced in the process deviation accumulation of the upper and lower components of tailgate frame, the gap of tailgate assembly is effectively ensured Face is poor；

The utility model is oppositely arranged on rear skirt section outside plate and tailstock skirt section inside panel that there are two be mutually matched to use Domes, this structure are mutually matched by two and half chambers, between two domes have closed cavity, this cavity is the The stress deformation of one domes provides deformation space, makes its inside crumple energy-absorbing, it is made to have had both good support strength And energy-absorbing effect；Wherein the first domes are located on the outside of the second domes, and the first domes can be reduced with crumple energy-absorbing It conducts to the impact force of the second domes, the second domes of effective protection, its deformation is avoided to cross macrolesion vehicle frame, the second arch Shape structure is located on the inside of the first domes, provides effective support for the first domes, improves the first domes Intensity, the first domes and the second domes complement each other improves integral strength and the torsion of tail skirt section assembly jointly Rigidity.
