Abstract

The utility model provides a structure used for improving the mounting clearance between a front bumper and a headlamp of a vehicle, which comprises a limit seat positioned on the front bumper and a positioning seat arranged on the headlamp, wherein the limit seat is at least two groove structures which are formed where the headlamp of the front bumper is turnup, and sunk from the inside to the outside; the limit seat is actually formed by converting a reinforcing rib, thus still playing roles in reinforcing and preventing the flanging of the headlamp of the front bumper form sinking and deforming; the positioning seat is an injection molding part; the upper end of the positioning seat is fixedly arranged at the lower edge of the headlamp by a screw and corresponds to the limit seat on the front bumper in position, and the lower end thereof is positioned in the limit seat, contacted but not connected with the bottom of the limit seat and freely arranged; and the limit seat is used for limiting the position of the positioning seat, thus achieving the positioning of the two. The structure improves the matched consistency and stability of the headlamp and the front bumper, has simple structure, is not easy to deform, is not influenced by proficiency level of assembling workers, and simultaneously also reduces the developing cost of new products.

Description

A kind of structure that car front bumper and headlight tolerance clearance are controlled

[technical field]

The utility model relates to the structure that car front bumper and headlight tolerance clearance are controlled.

[background technology]

The front bumper of car, head light all are that each personal screw of back is produced in injection moulding or clamp is directly installed on the vehicle body all the time, and be separate, very difficult for the tolerance clearance of controlling between them.Be contained on the vehicle body respectively for front bumper and headlight, and then lean on the state of nature after both assemblings to guarantee its gap between the two, this technology is simple, and is easy to process, but because bumper/spoiler is originally as big part, be difficult to control aspect distortion, add the two assembly error separately in addition, the assembly clearance between them just is difficult to guarantee stable and uniform, headlight is locked on the panel beating by three to four screws simultaneously, form a cantilever beam structure, and the weight of headlight own is heavier, stays easily.

[summary of the invention]

The purpose of this utility model is the deficiency at the prior art existence, a kind of structure that car front bumper and headlight tolerance clearance are controlled is proposed, improve the tolerance clearance of front bumper and headlight, and play the location and prevent the product distortion, to reduce batch process control, enhance productivity.

The technical solution adopted in the utility model is as follows:

A kind of structure that car front bumper and headlight tolerance clearance are controlled, it comprises the limit base that is positioned on the front bumper and is installed in positioning seat on the headlight.

Described limit base is at least two groove structures that caved in laterally by the inboard that form at the headlight flange place of front bumper, this limit base is actually by the reinforced rib conversion and forms, and still plays simultaneously and strengthens preventing that bumper/spoiler headlight flange place from staying the effect of distortion.

Described positioning seat is a moulding, the upper end is screwed and is installed in the headlight lower edge, and it is corresponding with the limit base position on the front bumper, the lower end of positioning seat is dropped in the limit base, with limit base bottom contact but be not connected, freely install, reach between the two location by limit base restriction positioning seat position.

As seen this structure has just been improved the tolerance clearance of front bumper and headlight by easy positioning seat of design, makes tolerance clearance between the two good, not influenced by workman's skill level, assembling is simple, stability is high, has improved quality, also improved simultaneously production efficiency, reduced and improved cost.

[specific embodiment]

Describe this structure in detail below in conjunction with accompanying drawing:

What Fig. 1 and Figure 1A were shown is a kind of front bumper 3 of car, in the Position Design of the installation headlight of front bumper 3 two limit bases 1 is arranged, and limit base 1 is the groove structure that is caved in laterally by the inboard that forms at the headlight flange place of front bumper.

Shown in Figure 2 is the positioning seat 2 that is used to be installed on the headlight, this positioning seat 2 is mouldings, is z shape, and there is screw hole the upper surface, be used for being installed in two screw posts of headlight 4 lower edges by screw retention, see Fig. 4, and corresponding with limit base 1 position on the front bumper 3, and the lower end of positioning seat 2 is dropped in the limit base 1, with limit base 1 bottom contact but be not connected, free state need not fixed, and sees Fig. 3.

The groove structure of limit base 1 plays the effect of reinforced rib again, and its degree of depth only needs the product wall thickness greater than positioning seat 2 lower ends and limit base contact portion, and the height of positioning seat 2 is freely to adjust design-calculated according to the position of the design gaps of safety lever and headlight and limit base.

The utility model utilizes bumper/spoiler, and this need design reinforced rib in headlight flange place, change reinforcing rib structure dexterously and made a limit base, be contained in the limit base with a positioning seat, positioning seat just can support headlight and prevent to stay influence assembly clearance between the two in limit base like this, make it keep stable and uniform, assemble simple and convenient.
