The technical solution is as follows:

the utility model provides a connection structure of backplate assembly and adjacent part on auto radiator which characterized in that, the front end of backplate assembly on the auto radiator adopts checkpost and preceding insurance assembly joint, the rear end of backplate assembly on the auto radiator passes through the screw and is connected with the water tank entablature.

The front end of the upper guard plate assembly of the automobile radiator and the matching surface of the front safety assembly are provided with 6 clamping parts, the clamp is arranged on the upper guard plate assembly of the automobile radiator, and the clamp is correspondingly matched with the mounting hole on the front safety assembly and used for limiting the displacement in the front-back direction; the front end of the automobile radiator upper guard plate assembly and the matching surface of the front bumper assembly are provided with 4 limiting structures, and the limiting blocks are arranged on the automobile radiator upper guard plate assembly, correspondingly matched with the mounting holes in the front bumper and used for limiting left-right displacement;

the clips and the limiting blocks are arranged on the front portion of the back face of the upper protective plate of the radiator in the same row at intervals and integrally injection-molded with the upper protective plate of the radiator, wherein the heights of the two clips in the middle of the row are larger than the heights of the other clips.

And a proper amount of interference is arranged at the lap joint of the front end of the upper guard plate assembly of the automobile radiator and the front bumper.

The utility model has the advantages that:

because the front end of the upper guard plate assembly and the front bumper assembly adopt a clamping structure, the traditional threaded connecting piece is not used, and a certain interference amount exists at the lap joint part, so that the gap between the assembled upper guard plate assembly and the front bumper assembly is ensured to be uniform, the appearance of the upper guard plate can be kept smooth and attractive, the installation and the disassembly are convenient, and convenience is provided for users.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Fig. 3 shows the positional relationship among the upper guard plate assembly 5, the front safety assembly 7 and the upper member assembly 6 of the radiator of the vehicle, in the prior art, the front end of the upper guard plate assembly 5 is lapped on the front safety assembly 7 and is fixed by a row of cross-shaped screw push nails, and the rear end of the upper guard plate assembly 5 is lapped on the upper member assembly 6 and is also fixed by a row of cross-shaped screw push nails.

Fig. 4 is a sectional view of the overlapping portion of the upper fender assembly 5 and the front bumper assembly 7.

The utility model discloses mainly have following two points to prior art's improvement.

Firstly, the connection of the front end of the upper guard plate assembly 5 and the screw thread push nail of the front safety assembly 7 is changed into clamping connection.

Referring to fig. 7, correspond in advance at 5 backs of upper protective plate assembly 7 lapped positions with preceding insurance assembly and designed one row of checkposts 8 and stopper 9, checkpost 8 and stopper 9 and the integrative injection moulding of upper protective plate assembly 5, the material is modified PP class material, in this example, checkpost 8 is 6, stopper 9 is 4, they alternate arrangement, and bilateral symmetry, wherein, the height that is located two checkposts 8 in the middle of is greater than the height of other 4 checkposts, plays the guide effect when the assembly.
