Description

Rear member with reinforcement structure in case of rear collision

The present invention relates to a rear member having a corresponding reinforcing structure in the event of a rear collision, and in particular, the rear bumper is formed to be combined without a separate rear bumper mounting bracket, thereby reducing assembly costs and reducing production costs, and at the same time deforming the rear body during a rear collision. Of the rear member with a corresponding reinforcement structure in the event of a rear collision that can reduce the fatal injury rate and improve safety because the reduced energy is efficiently transmitted to the passengers. will be.

Today's automobiles are recognized as a representative civilization in the industrial world because of their advanced technology and the addition of more comfortable and highly precise devices, which improve their maneuverability and usability. Nevertheless, a number of dangers follow because cars operate at high speeds and are driven on roads rather than tracks by people with different habits and functions. In particular, when a collision accident of a vehicle occurs, since the collision (kinetic) energy applied to the driver is large, there is a risk of a human accident that causes a fatal injury or death to the driver.

On the other hand, in order to prevent a fatal accident of the driver in the event of a crash, the front of the car so that the body is easily distorted to protect the passenger when the car crashes, and absorbs the kinetic energy according to the deformation to reduce the shock transmitted to the passenger. It consists of a crushable boby with a crush zone on its rear surface, and most automobiles now have such a body structure.

In addition, the secondary safety device of the vehicle is equipped with an energy absorber bumper equipped with a shock absorber (energy absorber) at the front and rear, respectively, and the airbag (airbag) to the front or side of the driver's seat and to the side seat (passenger seat). bag), and in case of a passenger car, a reinforcement is installed between the entire slope of the vehicle body or between the inner and outer panels of a specific part (loop panel, door, etc.), and when the vehicle accident occurs, The collision energy transmitted to the driver (passenger) is reduced to reduce the energy transmitted to the driver.

The conventional rear member to which the rear bumper as described above is mounted will be briefly described with reference to FIG. 1.

In Fig. 1, reference numeral 1 denotes a rear member, 2 denotes a bumper fixing bracket, and 3 denotes a rear bumper.

The rear members 1 are each bent in multiple stages in a predetermined shape, and both ends are bent again to form upper and lower flange portions 1a, respectively, and the inner and outer panels 1A and 1B. The upper / lower end portions are positioned between the upper / lower flange portions 1a of the < RTI ID = 0.0 >) < / RTI >

The bumper fixing bracket 2 is bent at a right angle and a coupling hole 2a is formed at one end thereof so that the other end is attached and fixed to an outer surface of the upper end of the outer panel 1B of the rear member 1.

In addition, the rear bumper 3 is protected to the rear body, and a fastening hole 3a is formed through the upper end at a predetermined interval, and the fastening hole 3a is connected to the coupling hole 2a of the bumper fixing bracket 2. Are positioned to be coupled to each other by fastening elements.

However, such a conventional rear member is manufactured by mounting the bumper fixing bracket separately, thereby increasing the number of assembly operations, reducing productivity and cost, and making the work cumbersome and inconvenient. As it was transmitted, the rate of fatal injury increased and the safety decreased, and the product quality and reliability of the product and the customer satisfaction were deteriorated due to the weakness in complying with the safety regulations of the performance test.

Therefore, the present invention has been devised to solve the fundamental problems of the prior art, the purpose of which is that the rear bumper is combined without a separate rear bumper mounting bracket to reduce the assembly labor and production cost and at the same time the rear part in the rear collision Rear with a reinforcing reinforcement structure in the event of a rear collision that reduces the amount of deformation of the vehicle body and efficiently reduces the impact energy applied uniformly so that the reduced energy is weakly transmitted to the passengers, thereby reducing the fatal injury rate and improving safety. To provide a member.

In order to achieve the above object, the present invention is a rear member formed so that the inner / outer panel and the reinforcing member are coupled to each other and the rear bumper is mounted on the outer panel, the upper portion of the outer panel of the rear member is bent and predetermined A fixed protrusion having a plurality of coupling holes penetrated at a predetermined length and extending rearwardly is formed, and a sub reinforcing member is formed in which one end is attached to the reinforcing member and the other end is attached to and fixed to the inner side of the fixed protrusion. To provide a rear member having a corresponding reinforcement structure in the event of a rear collision.

In the present invention as described above, the rear bumper is formed without a separate rear bumper mounting bracket to reduce the assembly labor and production cost, and at the same time reduce the amount of deformation of the rear body during the rear collision and uniformly deformed impact energy As the reduced energy is transmitted to the passengers weakly, the fatal injury rate is reduced and the safety is increased. In addition, the safety and reliability of the product can be improved and the customer satisfaction can be improved by complying with safety regulations of the performance test. .

(Actual example)

Hereinafter, a preferred embodiment of the present invention as described above with reference to the accompanying drawings in more detail as follows.

2 is a perspective cross-sectional view of a rear bumper coupled to a rear member having a corresponding reinforcing structure in the rear collision according to a preferred embodiment of the present invention.

As can be seen from this, the rear member 10 of the present invention is bent in multiple stages, the inner / outer panels (11, 12) formed of a predetermined shape are formed, respectively, between the reinforcing members are coupled to each other ( 13 is formed and the rear bumper 20 is mounted to the outer panel 12 by a fastening element.

An upper portion of the outer panel 12 of the rear member 10 is bent to extend rearward a predetermined length and a fixed protrusion 12A through which a plurality of coupling holes 12a penetrate at a predetermined interval is formed and the reinforcing member 13 The sub reinforcing member 14 is formed so that one end is attached and the other end is fixed to the inner surface of the fixed protrusion 12A.

Rear member having a corresponding reinforcing structure in the rear collision of the present invention having the configuration as described above is assembled and reinforced as follows.

First, one end of the sub reinforcing member 14 is fixed to the inner side of the fixed protrusion 12A of the outer panel 12 so that the sub reinforcing member 14 is positioned in the upper space between the outer panel 12 and the reinforcing member 13. The other end is attached and fixed to the upper side of the reinforcing member 13, and the upper and lower ends of the reinforcing member 13 are fixed to the upper and lower ends of the outer panel 12, respectively.
