Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a front bumper for an automobile, and in detail, 3
By dividing into two parts, the repair cost can be reduced and the cooling capacity can be improved.

<Prior art and its problems> A front bumper made of steel plate press-molded products or urethane resin injection-molded products is provided at the front end of the car body to reduce damage to the car body and protect pedestrians in the event of a collision. Has been.

As shown in FIG. 3, the front bumper 1 is usually made by integral molding, and is located below the grill 3 which is an air introduction hole to the radiator 2 and forms the forefront portion of the vehicle body 4.

On the other hand, the radiator 2 is located behind the grill 3,
The traveling wind that has passed through the grill 3 is guided to the radiator 2 as cooling wind.

By the way, since many conventional bumpers are integrally molded, repairing (replacement) when the front bumper 1 is damaged at the time of a collision involves a great deal of cost and becomes a problem. There is also a front bumper 1 divided into a center bumper and a side bumper, but in that case as well, since each is connected, if either side bumper is greatly deformed, the center bumper is also deformed. However, the repair cost was often high.

On the other hand, of the traveling air that hit the front of the vehicle body, the main air that is introduced into the radiator 2 as cooling air has passed through the grill 3, and the portion that hit the front bumper 1 was wasted. Therefore, in order to secure the cooling capacity of the radiator 2, it is necessary to take measures such as increasing the diameter of the cooling fan, resulting in increased noise and loss of horsepower.

The present invention has been made in view of the above situation, and an object thereof is to reduce the repair cost and improve the cooling performance by changing the configuration of the front bumper.

<Means for Solving the Problem> Therefore, in order to solve this problem, the present invention provides a front bumper which is provided in front of a radiator of an automobile and serves as a buffer in the event of a collision. The center bumper is divided into three parts, each of which is independently attached to the vehicle body, and the end portion of the side bumper on the vehicle body center side is provided with an air guide plate for guiding the traveling wind to the radiator. The present invention proposes a front bumper characterized by being formed.

<Function> Since the bumper is divided into three parts and the bumpers are not connected to each other,
Even if one of the side bumper and the center bumper is damaged due to a collision, the damage is unlikely to reach the adjacent bumpers, and the detaching work at the time of replacement can be performed individually. Further, since the end portion of the side bumper on the center side of the vehicle body serves as a wind guide plate, the amount of traveling wind introduced into the radiator increases.

<Embodiment> An embodiment in which the present invention is applied to a two-seater passenger car will be specifically described below with reference to the drawings.

FIG. 1 shows a perspective view of this passenger car, and FIG. 2 shows a cross section of the front part. In the description of the embodiments, the same members as those in the above-described conventional example are designated by the same reference numerals, and duplicated description will be omitted.

In FIG. 1, a center bumper 5 made of a steel plate is provided at the center of the front end of the vehicle body 4, and side bumpers 6 made of urethane resin are provided on the left and right sides.
7 are attached respectively. The center bumper 5 is
The front surface of the side bumpers 6 and 7 is protruded as compared with the side bumpers 6, while a gap 9 is provided between the upper end and the deck 8. The gap 9 serves as an air intake port to the radiator 2.

Further, the side bumpers 6 and 7 are bent at the ends on the vehicle body center side to form a baffle plate portion 10 to the radiator 2. The lower part of the center bumper 5 goes under the vehicle body,
The underguard portion 5a is formed.

The operation of this embodiment will be described below.

In this embodiment, the center bumper 5 and the side bumpers 6 and 7 are mounted independently and offset in the front-rear direction. Therefore, even if one of them is deformed due to a collision with a vehicle or the like, it is deformed like the conventional one. It does not extend to adjacent objects, and can be individually attached and detached during repair or maintenance.

Further, the end portions of the side bumpers 6 and 7 on the vehicle center side are located at the baffle plate portion 10.
Therefore, most of the traveling wind hitting the front surface of the vehicle body can be used as cooling air, and the cooling capacity is improved. Further, the amount of introduced air can be set in a wide range by appropriately setting the inclination (frontage) of the baffle plate portion 10, so that the degree of freedom in designing the cooling system is improved.

Further, in this embodiment, since the lower part of the center bumper 5 is the underguard portion 5a, when approaching a hill of earth and sand, the portion acts as a sled, and the crossing ability is improved.

Although the present invention is applied to the front bumper of a two-seater passenger car in this embodiment, it may be applied to a front bumper of a freight car or a four-seater passenger car of a monocoque body. Further, the materials of the center bumper and the side bumper are not limited to those in the embodiment, and may be FRP or the like.

<Effect of the Invention> In the present invention, the front bumper is divided into a side bumper and a center bumper that also serves as an underguard, and each of them is independently attached to the vehicle body. This has the effect of facilitating the work for replacement and reducing the cost for repair.

[Brief description of drawings]

FIG. 1 is a perspective view of a passenger car equipped with a front bumper according to the present invention, and FIG. 2 is a transverse sectional view of a front portion. Further, FIG. 3 is a perspective view of a front portion of a passenger vehicle to which a conventional front bumper is attached. In the figure, 1 is a front bumper, 2 is a radiator, 4 is a vehicle body, 5 is a center bumper, 6 and 7 are side bumpers, and 10 is a baffle plate portion.

Claims (1)

[Scope of utility model registration request] 1. A front bumper which is provided in front of a radiator of a vehicle and serves as a buffer in the event of a collision, and is divided into three side bumpers, a left and right side bumper and a center center bumper, each of which is independently mounted on a vehicle body. A front bumper, which is attached and in which a vehicle body center side end portion of the side bumper forms a baffle plate to the radiator so as to guide traveling wind to the radiator.
