Abstract

PURPOSE: A chassis frame mounting structure has a reinforcing member copping with external impact. CONSTITUTION: A "U"-shaped reinforcing member(64) is fixed by a bolt between a center floor side member(58) and a reinforce installed right under a center floor(50) to transmit external impact to the center floor side member(58), the "U"-shaped reinforcing member(64) and the reinforce simultaneously to disperse force. A "U"-shaped pipe is installed inside the "U"-shaped reinforcing member(64) to reinforce the "U"-shaped reinforcing member(64). The center floor(50), the side part of the center floor side member(58), the side part of the reinforce and the "U"-shaped reinforcing member(64) are layered in order.

Description

Chassis frame mounting structure of a vehicle

The present invention relates to a chassis frame mounting structure of a vehicle, and more particularly, to a chassis frame mounting structure of a vehicle provided with a reinforcing member configured to counter the impact (F) transmitted from the outside of the chassis frame mounting structure of the vehicle. It is about.

In general, the chassis frame mounting structure of the vehicle uses a reinforcing member to counter the force (F) transmitted from the outside of the vehicle. However, since the impact transmitted to the vehicle is different according to the chassis frame mounting structure, research is being conducted in each automobile company to make a safe driving by investing much in the chassis frame mounting structure.

FIG. 1A is a modification of the vehicle body in a conventional 40% offset collision, and FIG. 1B is a sectional view taken along the line A-A of FIG.

As can be seen in FIG. 1A, the chassis frame structure of the vehicle is provided with a subframe 12 adjacent to the front side member 10 and against external shock, and the front side member ( 10, a center floor 14, a tunnel part 16, a center floor side member 18 and a side seal 20 are installed at one side. do.

In particular, the external shock is transmitted along the arrow (→) shown in FIG.

As can be seen in FIG. 1B, the center floor 14 is provided with a center floor side member 18 and a rain force 22 at regular intervals below the center floor 14.

The chassis frame mounting structure of a conventional vehicle has not only severe deformation of the vehicle at the time of an accident because all external shocks (F) transmitted through the subframe are carried out along the center floor side member, and mounting structure of the chassis frame at the time of the vehicle accident. Due to the problem that the injury of the driver's pelvis and knee below is greatly generated.

In order to solve the above problems, the present invention adopts a structure in which the chassis frame mounting structure is provided with a U-shaped reinforcement member connecting the center floor side member and the rain force so as to improve driver safety, and in particular, An object of the present invention is to provide a chassis frame mounting structure of a vehicle having a structure capable of protecting the driver in the event of a vehicle accident.

In order to achieve the above object, the present invention, in the chassis frame mounting structure of the vehicle installed so as to sequentially absorb the external shock to the sub-frame, the front side member, the center floor and the center floor side member, The U floor reinforcement member is bolted between the center floor side member formed in the lower part and the rain force, and external shock is simultaneously transmitted to the center floor side member, U type reinforcement member and the rain force to distribute the force. It provides a chassis frame mounting structure of the vehicle, characterized in that formed as.

Hereinafter, the configuration and operation of the present invention with reference to the accompanying drawings.

FIG. 2 is a skeleton view showing the application area of the present invention, in which the vehicle body installed in front of the vehicle 30 has the engine 34 installed in the engine room when the hood is opened, and the engine 34 installed thereon. The engine support 38 is installed at the bottom. The overall structure for supporting the engine room is composed of a subframe 40, a front side member 44, and an internal partition 48. The subframe 40 serves to reinforce the vehicle body, and the inner partition 48 distinguishes the engine room from the interior of the vehicle and installs an instrument panel on the indoor side.

3A is a modified view of the vehicle body at 40% offset collision of the present invention, FIG. 3B is a sectional view taken along the line A-A of FIG. 3A, and FIG. 3C is a sectional view taken along the line B-B of FIG. 3A.

As can be seen in Figure 3a, the impact (F) transmitted from the outside of the vehicle body proceeds along the arrow, the front side member 44 is installed on the side of the sub frame 40 and the front side member 44 An inner partition 48 is connected and the center floor 50 is coupled to the rear of the inner partition 48. A tunnel portion 54 and a center floor side member 58 are coupled to the center floor 50, and a side seal 60 is formed at a side surface of the center floor 50. The sub frame 40 is provided with a U-shaped reinforcing member 64 immediately thereafter to transmit external shocks to the center floor side member 58. The U-shaped reinforcement member 64 is provided with a U-shaped pipe 68 configured in a U-shaped shape on the inner side so as to counter the external impact.

As can be seen in FIG. 3B, the center floor 50 has a center floor side member 58 and a rain force 70 coupled directly below the center floor 50, between the center floor side member 58 and the rain force 70. The U-shaped reinforcement member 64 is installed to be coupled to both sides by a bolt.

The center floor 50, the center floor side member 58 side, the rain force 70 side, and the U-shaped reinforcement member 64 are coupled in a structure stacked sequentially from the top to the bottom.

As can be seen in Figure 3c, the U-shaped reinforcement member 64 is formed in a structure that reinforces against the impact by installing a U-shaped pipe 68 inside.

As described above, the U-shaped reinforcing member 64 of the present invention is strongly resistant to external impacts between the center floor side member 58 and the rain force 70 formed below the center floor 50. Since it is formed in a structure that can counter, it solves the problem of being deeply deformed inside by a collision even if an accident occurs during the operation of the vehicle.

Referring to the effects on the configuration and operation of the present invention described above are as follows.

The U-shaped reinforcing member of the present invention is installed at a portion remaining as a weak point between the center floor side member and the rain force, which are formed directly below the center floor, so that the U-shaped reinforcing member can be appropriately opposed to the impact transmitted from the outside of the vehicle Even if an accident occurs while driving, it is possible to obtain an effect that can prevent injuries caused to the driver.

In addition, since the U-shaped reinforcement member is used, the front side member rear portion does not need to be installed, thereby reducing the overall weight, and thus, the vehicle body may be applied to an optimized design.
