At present, rear guarantor's crossbeam electrophoretic type is divided into following two kinds substantially: one is the independent electrophoresis excessively of rear guarantor's crossbeam, is arranged on vehicle body after making pitch-dark; Protect after another kind of crossbeam first with auto-body assembly after, with car electrophoresis.Protect crossbeam electrophoresis after first kind of way abundant, basic non-corroding problem after installing, but need to make frock electrophoresis separately, transhipment is more complicated, also easily causes part to collide with in transport process, electrophoretic paint such as to drop at the defect, and cost is higher; Crossbeam is protected without the need to independent electrophoresis after the second way, electrophoresis process is easier, logistics mode is easy, cost is lower, but rear guarantor's crossbeam and vehicle body install the laminating of coupling surface large area, and electrophoresis liquid cannot be infiltrated and be caused electrophoresis bad, and later stage easy-to-rust affects complete vehicle quality and outward appearance.
For the problem that the second way produces, the processing mode of current employing increases pad between rear guarantor's crossbeam and the attachment face of vehicle body, first carry out electrophoresis by after rear guarantor's crossbeam and vehicle body directly reserved certain electrophoresis gap, electrophoresis is complete again pad is taken off after, rear guarantor's crossbeam and vehicle body assemble again; Or be coated with the methods such as PVC glue at installation edge, coupling face and reach corrosion-proof requirement.But above method cost is higher, and technique is more complicated.
For the problems referred to above, providing a kind of novel anti-rust structure for protecting crossbeam after car, after making rear guarantor's crossbeam and auto-body assembly, making electrophoresis area reach maximum, and install without the need to repeating.
Utility model content
Technical problem to be solved in the utility model is, protects the anti-rust structure of crossbeam after providing a kind of automobile, the installation of rear guarantor's crossbeam and vehicle body is fitted little as much as possible, reduces the region that electrophoresis is bad, to reach corrosion-proof object.
For achieving the above object, the technical solution of the utility model is, the anti-rust structure of crossbeam is protected after a kind of automobile, it is characterized in that: described anti-rust structure is included on rear guarantor's crossbeam adapter plate and arranges antirust boss, protruding in the middle part of antirust boss, and center is provided with installation via hole, the bossing of antirust boss withstands Metal Sheets for Body-manufacturing and installs.
The magnitude setting of described antirust boss on rear guarantor's crossbeam adapter plate is three, distribution triangular in shape.
Described antirust convex edge of table is chamfering structure.
Protect an anti-rust structure for crossbeam after automobile, owing to adopting above-mentioned structure, the utility model greatly reduces the region of rear guarantor's crossbeam with electrophoresis non-after car electrophoresis, reduces corrosion.It is more that other face of rear guarantor's crossbeam adapter plate all exceeds boss face, can cover in corrosion region, ensure appearance looks elegant, and cost there is no increase.Rear guarantor's crossbeam and vehicle body cover are fitted from large face and are become several little and fit, and the tolerance of rear guarantor's crossbeam reduces, the difficulty that the part of reduction is produced.

Fig. 2 is the A-A section-drawing protecting the anti-rust structure of crossbeam after a kind of automobile of the utility model;
In Fig. 1-2,1, adapter plate; 2, antirust boss; 3, Metal Sheets for Body-manufacturing.
Detailed description of the invention
The utility model is included on rear guarantor's crossbeam adapter plate 1 and arranges antirust boss 2, protruding in the middle part of antirust boss 2, and center is provided with installation via hole, and the bossing of antirust boss 2 withstands Metal Sheets for Body-manufacturing 3 and installs.The magnitude setting of antirust boss 2 on rear guarantor's crossbeam adapter plate is three, distribution triangular in shape.The edge of antirust boss 2 is chamfering structure.
Specifically as shown in Figure 1, the utility model provides a kind of rear guarantor's crossbeam installation base structure, antirust boss 2 shapes are circular, also according to the concrete structure of adapter plate 1 and position, antirust boss 2 can be set to other shape, minimum boss area is advisable to protect transom bolt after energy normal mounting, too small then protect that crossbeam hold-down bolt and boss interfere afterwards can not normal mounting, the excessive then area that guarantor's crossbeam mates binding face with vehicle body afterwards increases, the increase of corrosion risk.The minimum constructive height of antirust boss 2 can be as the criterion by rear guarantor's crossbeam adapter plate other face except boss binding face smoothly with electrophoresis liquid, the material that maximum height specifically need be selected according to rear guarantor's crossbeam adapter plate and determining, and need meet the punching formation property of material.Edge chamfer process, this highly ensure that rear guarantor's crossbeam and vehicle body are installed and had enough electrophoresis gaps, and only installation base face place small part binding face cannot electrophoresis, its lap all can electrophoresis abundant.Antirust boss 2 center perforate, provides rear guarantor's crossbeam to install via hole.
This antirust boss 2 arranges three distributions triangular in shape on rear guarantor's crossbeam adapter plate, and its distribution form ensure that rear guarantor's crossbeam is firmly installed, and decreases coupling face the tolerance of rear guarantor's crossbeam adapter plate is tailed off, and part is easy-formation more.
