Abstract

PURPOSE: A side step device of a vehicle is provided to reduce the number of parts and secure passenger's safety by reducing entry into the room of a side sill and minimizing impact load transmitted to a passenger, in a side collision. CONSTITUTION: In a side step device of a vehicle, a side step plate is disposed inside a slide door(20), and a guide rail(27) guiding movement of an upper side step sill and the slide door are installed to the lower end of the side plate. A lower side step sill is disposed to the lower end of the guide rail. The lower end portion of the slide door contacts the side sill formed by mutually melting and compressing a side outer panel(22), a side lower sill(23), and a side inner sill(24). The guide rail where a roller(25) is inserted in vertical flanges(23a,24a) is melted and compressed to the side lower sill and the side inner sill. A rear floor(26) is melted and compressed to a side of the side inner sill. Thus, number of parts is reduced and passenger's safety is improved.

Description

Side step device for vans {SIDE STEP DEVICE FOR BUS}

According to the present invention, the lower side of the slide door is closely adhered to the side seal formed by fusion of the side outer panel and the side lower and side inner seals, and the guide rail having the roller inserted into the vertical flange extended to the side lower seal and the side inner seal is fused. As the rear floor is fused to one side of the inner side of the inner chamber, the number of parts can be reduced, and the impact load applied to the human body in the event of a side collision can be reduced, and the deformation amount can be minimized.

The present invention relates to a side step device of a van, and more particularly, by forming the step structure of the van in an integrated manner without distinguishing it from a floor in the room, further reducing the number of parts due to separation. The present invention relates to a side step device of a van, which reduces the impact load on the human body in the event of a side collision and minimizes the amount of deformation.

In general, as shown in Figure 1, the vans have a slide door on the side, and a step lower than the floor surface of the room is provided to facilitate getting on and off when the door is opened.

Conventional vans include a slide door 11 provided on the side of the van, a side step plate 12 inside the slide door 11, and the side of the slide door 11. An upper side stem chamber (StepSill Side Uper) 13 is installed at the bottom of the step plate 12 and a guide rail 14 for guiding movement of the slide door 11 at the lower side of the upper side step chamber 13 is installed. A lower side step seal (15) at the lower end of the guide rail (14), a center reinforcement part (16) located at an upper part of which the side step plate (12) is bent upward by a predetermined height; The floor board and the floor mat 17 are installed at the same height as the center reinforcement 16, and the rear floor 19 is installed at the lower part of the rear frame 18 to be fused.

However, the side step device configured as described above has a problem in that the structure is complicated and the number of parts is increased since the floor and the step part are separated, and in particular, the rigidity is weak during side impact.

The present invention is to solve the above problems, the present invention is the lower end of the slide door is in close contact with the side seal configured side fusion of the side outer panel and the side lower and side inner seal and extending to the side lower seal and side inner seal The guide rail in which the roller is inserted into the vertical flange is fused and the side inner chamber is formed of a rear floor fused to one surface of the side inner chamber.

Best Mode for Carrying Out the Invention A preferred embodiment of a side step apparatus for a van according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a view showing a side step device according to the present invention, the side seal 21, the lower end of the slide door 20 is in close contact with the side outer panel 22, the side lower chamber 23 and the side inner seal 24 The mutual fusion is configured, the vertical flanges 23a and 24a extend integrally with the side lower seal 23 and the side inner seal 24, and with the rollers with the vertical flange 24a of the side inner seal 24. The guide rail 26 into which the 25 was inserted is fused.

In addition, the rear floor 27 is fused to one surface of the side inner seal 24, and the floor plate 28 is fused to the upper portion of the rear floor 27.

In the side step apparatus of the van according to the present invention configured as described above, the side seal 21 has a side outer panel 22 and side lower and inner seals 23 and 24 so that the lower end of the slide door 20 is in close contact. After the welding, the slide door 20 is opened and closed while the guide rails 26 are welded to the vertical flanges 23a and 24a extending to the side lower and inner seals 23 and 24. It is opened and closed in a sliding manner by a roller 25 inserted into the guide rail 26.

In addition, the rigidity is increased as the rear floor 27 supports the side inner chamber 24 when the other vehicle collides in the vehicle side.

As described above, according to the side step device of the van according to the present invention, the lower end of the slide door is in close contact with the side seal formed by fusion of the side outer panel, the side lower and the side inner seal, and the side lower seal and the side inner seal Guide rails with rollers inserted on the extended vertical flanges are fused, and the rear floor is fused on one side of the inner side of the inner seal, thereby reducing the number of parts and reducing the impact load on the human body during side impacts, while minimizing the amount of deformation. The safety of passengers can be improved.
