The present invention relates to a shock absorbing door beam mounting bracket structure, and more particularly, a bracket installed to fix a door impact beam and a door impact beam for minimizing a human injury in a vehicle side collision. It relates to a shock-absorbing door beam mounting bracket structure that can absorb the impact when the impact is applied.

In general, the door of the vehicle serves as a collision load absorbing section for minimizing the injury value of the occupant during the side collision of the vehicle, in addition to the means for opening and closing as the driver and passenger enter the room.

As shown in Figures 1 to 3, the door of the vehicle forms a closed cross-section by the outer panel 10 and the mermaid panel 20 to the inside, the upper door frame is configured, the glass inside the glass The glass guide and the glass channel are configured at the bottom to move the glass up and down.

In addition, a door impact beam 30 is installed at the rear of the door outer panel, and mounting brackets 40a and 40 are installed at the front 40 and the rear 50 to be fixed to the mermaid panel 20 before and after the door impact beam 30. 50a) and a number of posterior support reinforcements 40b and 50b are combined. In order to minimize the pelvic injury value of the driver and passengers in the event of a side collision, the mermaid panel 20 should minimize the amount of indoor sliding while maximizing the energy absorption rate in the door impact beam 30, but the door impact beam of the prior art (30) is composed of a simple hollow beam is pushed into the room in the state of the initial deformation is insufficient in the event of a surface collision with the mounting brackets (40a, 50a) attached to the door mermaid panel 20 directly hit the pelvis of the driver There is a problem of being excessive.

Therefore, in order to reduce the head, ribs, and pelvic injury of the driver and passenger during side impact of the car, the optimal design of the door structure is being studied, and the door impact beam of the prior art has a simple hollow cross section Energy absorption rate is small The driver's door is too much The problem is that the pelvic injury value increases. In addition, the cost increase factors are caused by the increase in the number of parts and the number of assembly operations by the front and rear beam bracket and rain force for fixing the impact beam.

The present invention has been proposed to solve the above problems, by changing the shape of the mounting bracket for fixing the door impact beam shock-absorbing door beam mounting bracket that can absorb the impact when the impact on the door impact beam The purpose is to provide a structure.

The impact-absorbing door beam mounting bracket structure according to the present invention for achieving the above object includes a seating plate on which both ends of the door impact beam are installed, an extension plate extending to be bent at the end of the seating plate, and an end of the extension plate. The shock absorbing plate is formed to be bent to extend, the gap holding plate extending perpendicular to the end of the shock absorbing plate and the coupling plate extending to be bent at the end of the gap holding plate.

Hereinafter, the configuration of the shock-absorbing door beam mounting bracket structure and its embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

Figure 4 is a perspective view of the structure of the shock absorbing door beam mounting bracket according to the present invention, Figure 5 is a cross-sectional view of the structure of the shock absorbing door beam mounting bracket according to the present invention, Figure 6 is a shock absorbing door according to the present invention A combined perspective view of the beam mounting bracket structure.

The technical content of the present invention is to provide a shock-absorbing door beam mounting bracket for reducing the pelvic injury of the driver by maximizing the energy absorption rate in the side impact, the configuration is as follows.

The door impact beam 300 is installed along the longitudinal direction of the door in order to minimize the side impact when installed inside the door of the vehicle when the side impact.

Mounting brackets 400 are respectively installed at the front and rear of the inner panel 200 so that the door impact beam 300 installed along the longitudinal direction of the door can be fixed and installed.

The mounting bracket 400 is formed by a plurality of bendings two or more times. The shape of the mounting bracket 400 is applied to the bracket 400 that fixes the door impact beam 300 by applying an impact to the door impact beam 300 during a side collision of the vehicle. When an impact is applied, the impact is formed to be absorbed in multiple stages along the bent surface, and its configuration is as follows.

A seating plate 410 is provided so that both ends of the door impact beam 300 provided on the door inner panel 200 may be installed in order to reduce the impact amount when the side collision of the vehicle to prevent the injury of the occupant. A mounting groove 411 is further formed at the center of the mounting plate 410 so that both ends of the door impact beam 200 may be seated and fitted.

An extension plate 420 is bent to extend at an end portion of the seating plate 410.

The end of the extension plate 420 is provided with the shock absorbing plate 430 is formed to be extended. The shock absorbing plate 430 is configured to absorb the shock as it moves to the inside of the door when the impact is applied to the door impact beam 200.

An end portion of the impact absorbing plate 430 is provided with a vertically spaced gap retaining plate 440. An end portion of the gap retaining plate 440 is provided with a bent coupling plate 450. The reason why the space maintaining plate 440 is configured is that a certain space must be formed between the shock absorbing plate 430 and the coupling part 450 to provide a space in which an elastic force can be applied when an impact is applied to the door impact beam 300. This is because the shock is absorbed.

In addition, the coupling portion 450 is bent twice so as to be coupled to the shape of the door inner panel 200 is coupled to the frame shape of the door is a strong coupling force.

In addition, the coupling part 450 is spot welded on the door inner panel 20, and the seating plate 410 is Co 2 welded to the door impact beam 30.

Therefore, in the process of absorbing the impact during the side impact of the vehicle, when the impact is applied to the door primarily, the impact on the door impact beam 300 installed between the inner panel 200 and the outer panel 100 of the door When the impact is applied to the bracket 400 which fixes and supports the door impact beam 300 by the impact received by the door impact beam 300, the shock absorbing portion formed by bending the bracket 400 ( 420 is bent to absorb the impact in multiple stages. Accordingly, the present invention can prevent the bracket from being pushed in the direction of the passenger and hitting the pelvis of the passenger directly.

As described above, according to the shock-absorbing door beam mounting bracket structure according to the present invention, when the impact is applied by bending the bracket two or more times, the multi-stage shock is absorbed along the bent portion, thereby reducing the amount of impact and absorbing the impact. Existing door impact beam is pushed into the interior of the door mermaid panel with the mounting bracket mounted directly on the driver's pelvis to solve the problem that the injury is excessive. In addition, it is possible to reduce the cost by deleting the rain force supporting the conventional bracket.
