Abstract

The utility model discloses a support structure at the lower part of a front bumper assembly, which comprises two bent L-shaped mounting brackets and two support foam blocks. The support structure is characterized in that the two support foam blocks are respectively provided with a positioning mounting hole, and the front surfaces of the two support foam blocks are adhered to the inside surface of the front bumper assembly so as to enhance the support stiffness of the lower part of the front bumper assembly; the positioning mounting holes on the two support foam blocks are respectively correspondingly matched with mounting buckles on the inside surfaces of the two end parts of the front bumper assembly; the two mounting brackets are respectively pressed against the rear surfaces of the two support foam blocks, so that the support foam blocks are blocked so as to limit the backward moving of the support foam blocks; and the vertical parts of the two mounting brackets are respectively connected and fastened with external radiator-bracket-connector plates which are positioned and connected to a car body. The support structure disclosed by the utility model is not only simple and practical in structure, but also has no requirement on the shape and space of the bumper, therefore, the support structure is high in feasibility; and the support structure is low in development cost, and is extremely convenient to install and remove.

Description

The supporting construction of a kind of front bumper assembly bottom

Technical field

The utility model belongs to automobile component, is specifically related to the supporting construction of a kind of front bumper assembly bottom.

Background technology

For satisfying protection pedestrian's requirement, the bottom of bumper/spoiler needs certain support stiffness, overturns in collision process to prevent shank.Therefore, a lot of automobiles can increase supporting construction in the bumper/spoiler bottom, and present supporting construction mainly contains following dual mode:

1, increase a beams of metal a in front bumper assembly d bottom, this beams of metal is connected with front anti-collision beam c through three support b, and this mode is to bumper/spoiler moulding and the bottom installing space (see figure 1) that has higher requirements.

2, increase the plastic supporting pieces I in the bumper/spoiler bottom, this plastic supporting pieces is anterior to be connected with the bumper/spoiler II, and the rear portion is connected with radiator bracket attaching parts (III), and this mode can increase more cost (see figure 2).

Increase the requirement of supporting construction to bumper/spoiler moulding and space here in order to be reduced in, cost-cutting satisfies the requirement of pedestrian protecting, need carry out certain improvement and optimization to said structure.

Summary of the invention

The purpose of the utility model provides the supporting construction of a kind of front bumper assembly bottom, and it is simple and practical, and is low to bumper/spoiler moulding and space requirement; Easy accessibility; Cost of development is low, and ability actv. assurance thick stick lower support rigidity satisfies the pedestrian protecting requirement.

The supporting construction of the described a kind of front bumper assembly of the utility model bottom; Comprise two mounting bracket, two support foam blocks that bending is L-shaped; It is characterized in that: be respectively equipped with a location mounting hole on said two support foam blocks; Two are supported the front of foam block and the inside face applying of front bumper assembly, are used for strengthening the support stiffness of front bumper assembly bottom; Two support on the foam block the location and installation hole respectively with the installation buckle corresponding matching that is located on the inside face of front bumper assembly both ends; Said two mounting brackets respectively with two back of supporting foam blocks near, block the support foam block, support foam block with restriction and move backward; The vertical part of two mounting brackets respectively be located by connecting on car body on radiator bracket attaching parts outside plate be connected fixing.

The supporting construction of described a kind of front bumper assembly bottom, the left and right sides of its said each support foam block is close to two spacing buckles that are located on the inside face of front bumper assembly both ends respectively, supports the foam block sway with restriction.

The shape of said support foam block is according to the styling design of bumper/spoiler, and the inside face of front end face and bumper/spoiler is fitted, and does not receive bumper/spoiler moulding and space constraint; Compared with prior art design freedom and flexibility; And volume is little, and is lower than plastic supporting pieces cost, can be used on the various vehicles.Only need on front bumper assembly, increase by one is that buckle and two spacing buckles are installed, and just can be installed on the front bumper assembly supporting foam block.

The material of described support foam block is the EPP foamed materials, and described mounting bracket is a metal piece, and described installation buckle is a Plastic Parts.

The utility model is compared with prior art and is had the following advantages: not only simple and practical because the structure that supports foam block and mounting bracket all can be according to bumper/spoiler moulding and spatial design, and bumper/spoiler moulding and space do not required the feasibility height; Can not change other structures of car body owing to increase support foam block and mounting bracket, therefore, cost of development is low; Because support the both sides that foam block and mounting bracket only need be installed in bumper/spoiler, therefore, Assembly &Disassembly is all very convenient.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to describe.

Referring to the supporting construction of a kind of front bumper assembly bottom shown in Figure 3, comprise that two L-shaped mounting brackets of bending 3, two support foam block 2; Said two fronts of supporting to be respectively equipped with 5, two supports of location mounting hole foam block on the foam block 2 and the inside face of front bumper assembly 1 are fitted, and are used for strengthening the support stiffness of front bumper assembly bottom; Two support on the foam block location and installation hole 5 respectively with installation buckle 6 corresponding matching that are located on the front bumper assembly 1 both ends inside face; Said two mounting brackets 3 respectively with two back of supporting foam blocks 2 near, block the support foam block, support foam block with restriction and move backward; The vertical part of two mounting brackets 3 respectively be located by connecting on car body on radiator bracket attaching parts outside plate 4 be connected fixing; The left and right sides of said each support foam block 2 is close to two spacing buckles 7,8 that are located on the front bumper assembly 1 both ends inside face respectively, supports the foam block sway with restriction.

Said bumper/spoiler bottom section mounting means is: pass through to install buckle 6 clampings between front bumper assembly 1 and the support foam block 2; Support directly face applying between foam block 2 and the mounting bracket 3; Need not increase type of attachment; The vertical part of mounting bracket 3 is welded on the radiator bracket attaching parts outside plate 4, and radiator bracket attaching parts outside plate 4 is fastened on the car body.

One side referring to Fig. 4, Fig. 5 and support foam block 2 shown in Figure 6 is consistent with the inner surface configuration of bumper/spoiler 1, and fits with bumper/spoiler 1, supports the another side and mounting bracket 3 applyings of foam 2.
