Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for a bumper apron used to shield a space between a bumper provided at the front or rear of a vehicle and the vehicle body.

More specifically, the mounting piece of the panba apron is forcefully inserted into a recess provided on the vehicle body mounting surface, and the forceful insertion of the mounting piece into the recess creates a locking action between the fulcrum of the base of the mounting piece and the upper wall of the recess. A part of the cover of the apron is pressed against the top surface of the bumper while applying a preload load, which simplifies the installation work of the bumper apron, ensures installation, guarantees the sliding movement of the bumper apron, and prevents its deformation. This invention relates to a vehicle apron mounting structure.

2. Description of the Related Art As a bumper for a vehicle, an energy absorbing bumper is known in which a bumper beam is provided so as to protrude outward from a mounting surface of a vehicle body.

In this type of bumper, since the bumper beam projects outward, a space is created between the inner end surface of the bumper beam and the vehicle body mounting surface.

For this reason, a Pamba apron is used to shield this space from above.

This bumper apron is molded from a flexible elastic body or synthetic resin so as not to inhibit the movement of the bumper beam during a collision, and generally both front and rear ends of the apron are fixed to the bumper beam and the vehicle body mounting surface.

For this reason, it is not possible to follow the expansion and contraction of the apron that occurs due to temperature changes in winter and summer, and the apron becomes wavy due to changes in temperature, which may remain as distortion and impair its appearance.

In addition, in terms of installation work, identifying the front end of the apron individually with screws or the like increases the number of installation points, making the installation work troublesome and complicated, and it is desirable to improve this in terms of mass production of vehicles.

Therefore, it is possible to support the apron at one end so that it can slide freely against expansion and contraction or bumper movement in the event of a collision, but if the apron is provided on the front side, it may be lifted by wind pressure, or this may cause the upper surface of the bumper to This is not desirable as there is a risk of hitting the vehicle body.

The inventors of the present invention have devised the present invention in order to effectively solve the above-mentioned problems in attaching a Pamba apron.

The purpose of the present invention is to firmly insert the mounting piece of the panba apron into a recess provided on the vehicle body mounting surface, and to press fit the mounting piece into the recess to secure the connection between the fulcrum of the base of the mounting piece and the upper wall of the recess. To provide a bumper apron mounting structure for a vehicle in which a part of the cover of the apron is brought into pressure contact with the upper surface of the bumper while applying a preload load.

Therefore, the present invention has advantages such as easy installation, reliable support even though it is supported on a cantilever, and since it is supported on a cantilever, the apron can absorb expansion and contraction of the apron and movement of the bumper beam. Provide mounting structure.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 shows a front perspective view of the vehicle, this embodiment will be explained as an example applied to a front bumper, Fig. 2 shows a vertical side view of the apron alone, Fig. 3 shows a plan view, and Fig. 4 1 is a cross-sectional view taken along the line 4-4 in FIG. 1 showing the installed state, and FIG. 5 is an enlarged view of the main parts.

A front bumper 3 is provided at the lower front of a vehicle body 2 of a vehicle 1, and the front bumper 3 includes a front bumper beam 4, left and right bumper corners 5, 5, and a pane apron 6.

A rear bumper (not shown) at the rear of the vehicle body is similarly configured.

The bumper beam 4 is attached so as to protrude forward from the front lower mounting surface 2a of the vehicle body 2, as shown in FIG. 4b, and has a box-like cross section.

The bumper beam 4 is mounted so as to protrude forward from a mounting surface 2a at the lower front of the vehicle body via a bracket (not shown), and a space S is formed between the inner end of the bumper beam 4 and the mounting surface 2a, and the bumper beam 4 is attached to the vehicle as shown in FIG. A predetermined length is provided in the width direction of the space S, and thus a space S is also formed in the left-right direction.

The breadboard apron 6 has a cross section shown in FIG. 2, and includes a horizontal cover portion 6a that shields the space S from above, a front end portion 6b that is curved downward and projects slightly downwardly, and a portion of the cover. 6
It has a fulcrum part 6C that is located at the rear end of a and projects upward, and a mounting piece 6d that extends obliquely backward and downward from this part,
These are entirely molded from synthetic resin.

In this embodiment, two mounting pieces 6d are newly provided, spaced apart from each other on the left and right, as shown in the plan view of FIG.

On the other hand, the beam 4 on the mounting surface 2a of the bumper beam 4 of the vehicle body
A mounting recess 7 is provided at a position corresponding to the upper part, which extends to the rear when it is located on the inside, that is, on the front side. The width of the mounting piece 6d is larger than that of the mounting piece 6d described above, and two new pieces are provided in this embodiment to correspond to the mounting piece 6d.

The depth of the recess 7, that is, the depth dimension is larger than the mounting piece 6d, and the height, that is, the distance H between the upper wall 7b and the lower wall 7C, is from the aforementioned protrusion 6C of the apron 6 to the lower end of the mounting piece 6d. Set smaller than the height Hl of.

In the above, a seat 8 made of rubber or the like is pasted in the length direction on a portion of the upper surface 4C of the main body 4a of the bumper beam 4 near the space S, and an apron 6 is placed over this so as to shield the space S.

The mounting piece 6d of the apron 6 is fitted into the recess 7 from the open front side.

The lower end of the mounting piece 6d touches the lower wall 7C of the recess 7, and the fulcrum part 6C of the base of the mounting piece 6d touches the upper wall 7b.
As described above, since <Hl is greater than the height H of the recess 7, the lower end of the mounting piece 6d is bent upward as shown in FIG. 5, and therefore the mounting piece 6d is forcefully inserted into the recess 7C. That will happen.

By forcefully inserting the mounting piece 6d, a downward preload is applied to the cover portion 6a using the fulcrum portion 6C as a fulcrum so that the cover portion 6a is pressed against the upper surface 4C of the beam main body 4a, and is pressed downward against the seat 8 and fixed.

Therefore, the apron 6 is located on the space S and shields it, while a downward pressing force is constantly applied to it and is pressed onto the beam body.
The seat 8 is hidden from the front by the bent front end 6b.

The bumper apron 6 is attached to this side so as to cover the space between the bumper beam 4 and the vehicle body mounting surface 2a.

Next, to describe its function and effect, the apron 6 applies a downward preload load to the cover part 6a that shields the space as described above, so that the shielding is ensured, and the fixation to the bumper beam 4 is fixed to the bumper beam 4 without being cantilevered. However, it is certain.

Since it is attached by crimping, the apron does not lift up due to wind pressure while driving, even though it is supported on a cantilever.

In addition, since it is supported by a cantilever and is supported by the support piece 7 and not by fixed support such as screws, it is possible to slide in the length direction, and therefore thermal expansion and contraction can be tolerated, which is different from the conventional As a result, the apron 6 does not undergo corrugated deformation, which is good in terms of appearance, and since it is supported on a cantilever, the movement of the bumper beam 4 in the front and back direction is not inhibited.

Furthermore, there is no need to provide screw holes or the like on the vehicle body side, and therefore there are no through holes between the vehicle body and the interior of the engine room, and water leakage does not occur.

Furthermore, there is no need for screws, and the apron end can be securely installed just by inserting it into the recess, as described above, and the assembly work is extremely easy, making it suitable for mass production, simplifying the work, and saving labor. can be achieved.

As mentioned above, the improved apron can be applied to each of the front and rear bumpers, and it is needless to say that it is not limited to the front side as in this embodiment.
