Detailed Description

Embodiments of the present invention are described below with reference to the drawings.

It should be noted that the drawings are drawings showing only main structures for easy understanding of the present invention, and there are cases where a structure or a specific shape thereof which does not affect the understanding of the technical solution of the present invention is omitted, and these omitted parts (for example, specific shapes of members, connecting means, and the like) can adopt a known design or possible structures. In different embodiments, the same reference signs are used for the same or similar elements to facilitate comparison and understanding. In the following description, the up, down, left, right, front, and rear are based on the direction viewed by an occupant seated in a driver's seat, where the left-right direction is also referred to as the vehicle width direction.

Further, in the following description, various components of the vehicle body may be made of a metal material such as a steel plate, unless otherwise specified. The connections, joins, adhesives and attachments as used in the following disclosure may include various means of connection such as welding, stir welding, fastening (rivets, screws, clips, etc.) and adhesive bonding, and may be used interchangeably as desired. Further, since the vehicle body is substantially symmetrical about a center axis extending in the front-rear direction, the present embodiment is explained taking a rear side door structure on the left side of the vehicle as an example to avoid redundancy. In fact, the rear side door structure on the right side of the vehicle may have the same and symmetrical structure. Although the present embodiment is exemplified by a rear side door structure, those skilled in the art can apply the relevant design to door structures at other positions (e.g., front side doors) with reference to the following description.

In the following, fig. 1 is a schematic view of a vehicle according to an embodiment of the invention; fig. 2 is a side view of a vehicle body side structure according to an embodiment of the present invention; FIG. 3 is a partially enlarged view of the vehicle body side portion structure of FIG. 2; FIG. 4 is a partially enlarged view of a side structure of the vehicle body after the door is opened;

FIG. 5 is a partially enlarged view of the vehicle body side portion structure from another view; fig. 6 is a sectional view taken along line a-a' of fig. 2.

Specifically, the vehicle body side portion structure 100 of the present embodiment includes: a side sill (side sill) 110 extending in the vehicle body longitudinal direction 14 below the side portion of the vehicle body, a center pillar 120 rising upward and connecting the side sill 110, and a roof side rail 130 provided above the side portion of the vehicle body at an upper end of the center pillar 120, and together support a side door opening, such as a rear door opening 140, of the side portion of the vehicle body. The rear side door 200 is supported openably and closably by the corresponding vehicle body center pillar 120 via a hinge (not shown), for example. A door beam 210 made of a welded steel pipe or a stamped steel plate member is provided in the rear door 200 to improve the mechanical strength and rigidity of the rear door 200. In the present embodiment, the door beam 210 is inclined toward the rear lower side of the vehicle (i.e., the direction from the upper left to the lower right in fig. 2), and the inclined door beam 210 can increase the supporting area for the rear side door 200.

Further, the side sill 110 is composed of an inner side sill 112 and an outer side sill 114. Above the outer side sill 114, a reinforcement 300 corresponding to the rear side door 200 and the door beam 210 thereof is provided, which forms a hollow 301 having a closed cross section as shown in fig. 6 together with the outer side sill 114. The reinforcing member 300 has a bulkhead 310 supported between the reinforcing member 300 and the outer side sill 114 within the hollow portion 301 to reinforce the structure of the reinforcing member 300. It should be noted that the present embodiment provides the bulkhead 310 at a position overlapping the door beam 210 of the rear side door 200 in the vehicle width direction 12, and provides the bulkhead 310 obliquely in the longitudinal direction 16 of the door beam 210. In this way, when the vehicle is laterally impacted, the load input to the door beam 210 can be transmitted to the side sill 110 and other portions of the vehicle body through the reinforcement 300 and the bulkhead 310 inside thereof, so that the amount of deformation of the vehicle interior due to the lateral impact can be suppressed, and the safety during traveling can be improved.

It should be noted that the present embodiment may further have the front wall 310a or the rear wall 310b of the bulkhead 310 disposed along the door beam 210. For example, as shown in fig. 3, in a state where the rear door 200 is closed, the rear wall 310b of the bulkhead 310 is flush with the rear side 210b of the door beam 210. Alternatively, in other embodiments, not shown, the position of the bulkhead 310 may be moved forward such that the front wall 310a of the bulkhead 310 is flush with the front side 210a of the door beam 210. In this way, the angle of inclination of the bulkhead 310 is the same as the angle of inclination of the door beam 210, ensuring that the load of a side impact input to the door beam 210 can be transmitted to the reinforcement 300, and preventing the door beam 210 from being broken.

On the other hand, the vehicle body side portion structure 100 of the present embodiment further includes a reinforcement patch 400 that is located above the inner rocker 112 and is juxtaposed with the reinforcement 300 in the vehicle width direction 12. In other words, in the present embodiment, the reinforcing member 300 and the reinforcing patch 400 are respectively provided at the corresponding positions of the outer side and the inner side of the side sill 110, and when the vehicle is laterally impacted, the reinforcing patch 400 located at the inner side can reinforce the structure of the reinforcing member 300, thereby playing a role of assisting in absorbing and transferring the load, so that the load inputted to the door beam 210 is more completely transferred to the vehicle body through the reinforcing member 300 and the reinforcing patch 400.

In this embodiment, the reinforcement 300 and the reinforcement patch 400 may be fixed to the outer sill 114 and the inner sill 112 by various possible methods such as welding, riveting, or bonding. In particular, as shown in fig. 6, the inboard end 302 of the reinforcement 300 and the outboard end 402 of the reinforcement patch 400 are joined to the respective flanges 113 of the side sills 112 that form the rear side door openings 140 in the vehicle width direction 12. Therefore, the reinforcing effect of the whole structure can be enhanced, and the load absorption capacity is improved.

As shown in fig. 2, in the present embodiment, the front end portion 212 of the door beam 210 may be further extended to a position overlapping the vehicle body center pillar 120 in the vehicle width direction 12. In this way, the load of the side impact input to the door beam 210 can be distributed to the reinforcement 300 and the vehicle center pillar 120, and the amount of deformation of the vehicle interior due to the load can be effectively suppressed, thereby ensuring the safety of the vehicle occupant.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the invention in its corresponding aspects.
