Abstract

The utility model provides a tail bumper (1), tail bumper has recess (2), and this recess sets up the lower part of tail bumper's left and right sides end to be close to vehicle rear wheel (4) the side of recess (2) is the opening down. According to the utility model discloses, can restrain the production of the vortex with the rear guide to the vehicle of the vortex that is located the rear wheel rear to reduce the running resistance.

Description

Rear bumper

Technical field

The utility model relates to the rear bumper of vehicle.

Background technology

Usually, rolled-up in the driving process of the air flow through at the rear of the trailing wheel of vehicle at vehicle, because fitfull diffusion causes forming eddy current, like this, air is deteriorated in the flowing of rear view of vehicle.If air is deteriorated in the flowing of rear view of vehicle, then the negative pressure acting on the vehicle back side increases, and the resistance to motion of entire vehicle increases, and causes the reductions such as the fuel economy of vehicle.

Utility model content

The utility model proposes to solve the problem, and its object is to provide a kind of eddy current that can reduce the air that flows through at the rear of the trailing wheel of vehicle and cause, reduces the rear bumper of resistance to motion.

To achieve these goals, according to rear bumper of the present utility model, described rear bumper has groove, and this groove is arranged on the bottom of the left and right sides end of described rear bumper, and a side downwardly facing opening of the described groove of close vehicle rear wheel.

Preferably, a side of described groove extends along the outside of rear bumper with angle obliquely inside overall width direction.

Preferably, another side of described groove extends along the outside of rear bumper with angle obliquely or in the mode of level inside overall width direction.

Preferably, another side being positioned at the described groove of the left and right sides of described rear bumper is formed in the outside centre of described bumper/spoiler and connects.

According to the utility model, by arranging groove on rear bumper, the rear of the eddy current being positioned at trailing wheel rear to vehicle can be guided, suppressing the generation of eddy current, thus reduce resistance to motion.

Nomenclature:

1 is rear bumper, and 2 is groove, and 3 is the rear portion of vehicle, and 4 is trailing wheel, and x is that trailing wheel rolls air-flow, and y is that vehicle rear rolls air-flow.

Detailed description of the invention

Below, embodiment of the present utility model is described in detail with reference to accompanying drawing.

Fig. 1 is the partial schematic diagram seen from proceeds posterolateral of the rear bumper according to the utility model embodiment.The side of vehicle is illustrate only in figure.

As shown in Figure 1, rear bumper 1 has groove 2, groove 2 is arranged on the bottom of the left and right sides end of rear bumper 1, and a side downwardly facing opening of the described groove 2 of close vehicle rear wheel 4.

Aperture position is selected be in the object of the position near trailing wheel, rolled-up in the driving process of the air flow through at the rear of the trailing wheel of vehicle at vehicle, according to the setting of opening of the present utility model, as shown in Figure 2, trailing wheel is rolled air-flow x and is entered groove 2 and guided by the rear to vehicle, compared with the situation of the groove being with opening is not set, avoids the rear that the fitfull rolling air-flow x due to trailing wheel is diffused in the trailing wheel of vehicle and form eddy current.

Like this, directed trailing wheel is rolled air-flow x and is peeled off gradually, and rolls air-flow y collaborate at the position of rule relatively and vehicle rear as shown in Figure 3, air-flow is flow through swimmingly from the rear of vehicle, reduces resistance to motion thus.

In addition, as shown in Figure 1, a side of groove 2 extends along the outside of rear bumper 1 with angle obliquely inside overall width direction.Another side of groove 2 extends along the outside of rear bumper 1 with angle obliquely or in the mode of level inside overall width direction.Another side being positioned at the groove 2 of the left and right sides of rear bumper 1 is formed in the outside centre of bumper/spoiler 1 and connects.By making groove 2 be formed in the above described manner, the circulation of air-flow can be promoted further.

The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
