Description

A kind of split type boot-lid panel of automobile using

Technical field

Automobile component field is the utility model is related to, more particularly to a kind of split type boot-lid panel of automobile using.

Background technology

Luggage-boot lid is one of important feature of car body, and it mainly includes luggage-boot lid assembly and its other general assemblies are attached Part forms.Luggage-boot lid is connected through the hinge in car body on the whole, its mainly include luggage-boot lid outside plate, boot-lid inner panel with And lock reinforcer, hinge reinforcement composition, the taillight and decorative element of some automobiles are also connected on luggage-boot lid.In order to reasonable All parts, beautification vehicle are laid out, its moulding is complex, can not be made up of one piece of sheet material entirety punching press, typically more by two Block pressing sheet material is welded；But existing automobile-used split type boot-lid panel, because the structure of upper and lower cover plate combination and use The reason such as welding manner existing defects so that it is poor molding sense to be integrally present in row automobile Lee case, unsightly, and spillage of material With a variety of drawbacks such as process costs are higher.

Such as：1st, patent authorization number CN104228970A patent names are the technology of a kind of automobile and its luggage-boot lid outside plate Scheme, the combining structure of use is complex, and pad layout has been exposed on the outside of luggage-boot lid outside plate, need to be entered again using technique Row is covered, complex process, and cost of manufacture is of a relatively high.

2nd, the skill of a kind of luggage-boot lid welding structure of patent authorization number CN103817476A patent names and its welding method Art scheme, using pressure welding technology, so inevitably bring the plastic deformation at solder joint, it is impossible to obtain good outward appearance matter Amount.

3rd, the technical scheme of patent authorization number CN201737060U patent names vehicle trunk lid outer board, point of use welder Skill is connected, but spot welding impression can be so brought to outside plate, you must use additional materials and technique is used to block spot welding impression, The increase of overall cost of parts is brought, while exists on outside plate and is welded to connect parting line, presentation quality does not have associative perception.

The content of the invention

The utility model is completed to solve deficiency of the prior art, and the purpose of this utility model is to provide one Kind simple in construction, overall appearance, welding trace is not stayed and can reduce integrated artistic difficulty, makes production more efficient and a kind of economic automobile With split type boot-lid panel

The split type boot-lid panel of a kind of automobile using of the present utility model, including upper cover plate 1 and lower cover 2, wherein upper cover The bottom of plate 1 is to inner side bending, the top bending laterally of lower cover 2, the lower distal of upper cover plate 1 and the folding of lower cover 2 Crook is welded and fixed, and the lower distal of the upper cover plate 1 is provided with angle welding 3 with the bending weld of lower cover 2.

Preferably, in the angle welding 3 of weld described above, the angle welding 3 is closed provided with fluid sealant 4.

Preferably, the lower distal of upper cover plate 1 described above welds with the bending part of lower cover 2 for Laser Deep Penetration Welding It is fixed.

The split type boot-lid panel of a kind of automobile using of the present utility model, employs new connection and is welded and fixed structure, Reduce monoblock type luggage-boot lid sheet metal forming difficulty；Avoid occurring on the split type boot-lid panel of vehicle body be evident that weld seam, The impression of spot welding welding trace, Sheet Metal Forming Technology, avoid covering solder joint using the 3rd part, realize the associative perception and outward appearance in moulding The lifting of quality, simplifies production process steps, reduces cost.

Embodiment

Fig. 1 below in conjunction with the accompanying drawings to Fig. 3 is done into one to a kind of split type boot-lid panel of automobile using of the present utility model Step describes in detail.

The split type boot-lid panel of a kind of automobile using of the present utility model, it refer to Fig. 1 related each figures into Fig. 3.Such as Fig. 1 Shown in 3, including：Upper cover plate 1 and lower cover 2, the wherein bottom of upper cover plate 1 are to inner side bending, and the top of lower cover 2 is laterally Bending, the bending part of the lower distal and lower cover 2 of upper cover plate 1 are welded and fixed, and the lower distal of the upper cover plate 1 is with The bending weld of cover plate 2 is provided with angle welding 3, and in the angle welding 3 of weld, the angle welding 3 is closed provided with fluid sealant 4. Above-mentioned new connection and structure is welded and fixed, can avoid what is occurred on the split type boot-lid panel of vehicle body from being evident that weldering Seam, spot welding welding trace, the impression of Sheet Metal Forming Technology, avoid covering solder joint using the 3rd part, realize associative perception in moulding and The lifting of presentation quality, simplifies production process steps, reduces cost.

Preferably, the lower distal of upper cover plate 1 described above welds with the bending part of lower cover 2 for Laser Deep Penetration Welding It is fixed.As shown in figure 3, taking which to weld, its even weld, the welding droplet transfer is bridged using angle welding upper plate, is obtained Fine and close weld seam, laser downhand welding overlap joint is effectively avoided because carrying out surface irregularity matter apart from stomatal band caused by space between metal plate Measure defect.It can make it that welding effect is more preferable, realize the lifting of the associative perception and presentation quality in moulding, and avoid using laser Soldering processes use more expensive solder raw materials for production, avoid introducing the manufactured parts cost for being covered solder joint using the 3rd part and being brought Increase.Simultaneously Laser Deep Penetration Welding equipment investment compare conventional laser brazing equipment input can also be greatly reduced；And its is soft Property manufacturing capacity more meets the demand of flexible production line.

Finally, shown in Fig. 2, the weld seam of the structure of angle welding 3 is narrow, scrap (bridge) is narrow, laser welding heat input is small, may finally Obtain the joint for deforming small, even weld, intensity satisfaction requires.Just it is good to be reached outward appearance for joint covering to apply fluid sealant Vehicle effect.The weld of angle welding is sealed using fluid sealant, it is expensive with gluing generation to reduce solder filling work procedure Copper solder, material cost decreases, and simplifies production process steps, improve production efficiency.

It is above-mentioned that only several specific embodiments in the utility model are illustrated, but can not be used as of the present utility model Protection domain, equivalent change or modification or equal proportion amplification or contracting made by every design spirit according in the utility model It is small etc., it is deemed to fall the scope of protection of the utility model.
