Description

Side door with reinforced bracket of impact-bar for vehicles}

The present invention relates to a side door of a vehicle having an impact bar reinforcement bracket, and in particular, to improve the internal structure of the side door of the vehicle having an impact bar to reinforce the bracket supporting the impact bar, so that the bracket is separated from the outer panel during side impact. As a device to prevent the impact bar from being pushed into the cabin, the reinforcement bracket additionally provided in the side door of the vehicle reinforces the bracket supporting the impact bar, so that the impact bar is separated when the side of the vehicle collides. The present invention relates to a device that can prevent various types of crash safety standards by preventing the rushing inside and improve the safety and the merchandise of the vehicle by protecting the occupants.

In general, the side door of a car is mainly composed of an outer panel and an inner panel, and the interior of the vehicle is equipped with electrical equipment such as a power window regulator and a door actuator, and a window glass is installed to be able to lift up and down. Of course, it is designed and built to protect passengers from side collisions.

The general structure of the door is made by pressing steel plate to make outer panel and inner panel, and folding and welding their edges and joining them integrally. Is vulnerable.

In particular, since the rigidity of the outer panel and the inner panel against external force applied through the side of the vehicle is greatly reduced, in order to solve this problem, the side door of the side door is pushed into the inside of the vehicle by an accident. A high rigidity impact bar is provided horizontally or inclined in the longitudinal direction to prevent the vehicle from being prevented.

1 is a perspective view illustrating a side door of a vehicle having a conventional impact bar, and FIG. 2 is a cross-sectional view taken along the line A-A of FIG.

As shown in FIGS. 1 and 2, a side door of a vehicle having a conventional impact bar is disposed in a longitudinal direction so as to contact the outer panel 11 and the inner panel 12 and the inner surface of the outer panel 11. The impact bar 13 is positioned, and the bracket 14 fixing both ends of the impact bar 13 to the outer panel 11.

As shown in FIGS. 1 and 2, a side door of a vehicle having a conventional impact bar configured as described above has an impact bar 13 having an outer panel 11 and an inner panel 12 of the vehicle side door 10. Located between, both ends of the impact bar 13 are welded to the outer panel 11 by a bracket 14.

When the side impact is transmitted to the side door of the vehicle having the conventional impact bar as described above, the impact is first transmitted to the outer panel 11, and then the impact bar 13 fastened inside the outer panel 11. ) Is to prevent the side door 10 is pushed inward to protect the passengers.

At this time, the initial rolling of the impact bar 13 is greatly influenced by the bonding strength of the bracket 14 for fixing both ends of the impact bar 13 to the outer panel 11.

However, when the side door of a vehicle having a conventional impact bar has a side impact applied to the side door, the rigidity of the impact bar is so great that the weld joints of the brackets supporting both ends of the impact bar are separated, rather than the impact bar being bent. There was a technical problem that the impact bars of the side doors were pushed into the inside of the body, resulting in higher passenger injury.

The present invention is to solve the above problems, the reinforcement brackets additionally provided in the side door of the vehicle to reinforce the bracket for supporting the impact bar, the bracket is separated during the side impact of the vehicle to push the impact bar into the interior of the cabin The present invention provides a side door of a vehicle having an impact bar reinforcement bracket that prevents a phenomenon and satisfies various crash safety standards and protects occupants to improve safety and productability of the vehicle.

The present invention is an outer panel and an inner panel, an impact bar positioned in the longitudinal direction to contact the inner surface of the outer panel, and a side door made of a bracket for fixing both ends of the impact bar to the outer panel, one side of the The reinforcing bracket is fastened to the inner side of the bracket and the other side is fastened to the inner side of the inner panel to prevent the bracket from being separated from the outer panel.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a perspective view illustrating a side door of a vehicle provided with an impact bar reinforcement bracket according to the present invention, and FIG. 4 is a cross-sectional view taken along line B-B of FIG.

As shown in FIGS. 3 and 4, the side door of the vehicle having the impact bar reinforcement bracket of the present invention contacts the outer panel 110 and the inner panel 120 and the inner surface of the outer panel 110. In the side door (100) consisting of an impact bar (130) located in the longitudinal direction so as to be fixed to both ends of the impact bar (130) to the outer panel (110), one side of the bracket (140) The inner side of the) and the other side is fastened to the inner side of the inner panel 120, the reinforcement bracket 150 for preventing the bracket 140 from being separated from the outer panel 110 in the technical configuration that The basic features of the.

In this case, the reinforcing bracket 150 may be formed to be bent in a substantially '' 'shape.

Hereinafter, the operation of the present invention will be described with reference to FIGS. 3 and 4.

Side door of the vehicle having the impact bar reinforcement bracket of the present invention configured as described above is shown in Figures 3 and 4, the impact bar 130 and the outer panel 110 and the inner panel of the vehicle side door 100 Located between the panels 120, both ends of the impact bar 130 is welded to the inner surface of the outer panel 110 by a bracket 140.

At this time, the bracket 140 is bent in a substantially 'c' shape so that one side of the reinforcing bracket 150 welded to the inner surface of the inner panel 120 is fastened.

Therefore, when the side impact is transmitted to the side door 100 of the vehicle having the impact bar reinforcement bracket of the present invention as described above, the impact is first transmitted to the outer panel 110, and then, the outer panel 110 The impact bar 130 fastened to the inside of the side door 100 is to prevent the passenger to be pushed inward.

At this time, the initial rolling of the impact bar 130 is primarily prevented by the bracket 140 for fixing both ends of the impact bar 130 to the outer panel 110, and secondly to the bracket 140 By being prevented by the reinforcing bracket 150 supported on the inner panel 120, it is also possible to prevent separation of the outer panel 110 and the inner panel 120.

Thus, by additionally fastening the reinforcing bracket 150 coupled to the inner panel 120 on one side of the bracket 140 supporting the impact bar 130 of the side door 100, the side collision of the vehicle As the welding fastening part of the bracket 140 supporting both ends of the impact bar 130 is separated, the impact bar 130 of the side door 100 can be prevented from being pushed into the inside of the vehicle body. Not only are they satisfied, they can effectively protect the occupants.

As described above, the present invention provides a reinforcement bracket additionally provided to the side door of the vehicle to reinforce the bracket supporting the impact bar, thereby preventing the impact bar from being pushed into the interior of the vehicle during the side collision of the vehicle, thereby preventing various collisions. Not only satisfies the safety standards, it is an invention that can improve the safety and merchandise of the vehicle by protecting the occupants.
